In food processing, various types of continuous sterilization apparatuses have been used for sterilizing canned foods and beverages. While cans are still very popular for containing and processing foods, pouches and other types of containers are also becoming more widely used for food processing. For some food products, pouches are preferred because they are easier to open and easier to dispose of than cans. However, continuous processes, such as continuous rotary sterilization processes, are designed for use with cylindrical containers such as cans and not for pouches.
Carriers designed for use with continuous sterilization apparatuses that are capable of holding irregularly shaped and/or fragile containers, such as bottles, flat pouches, and other containers have been developed in the past. See, for example, U.S. Pat. Nos. 3,314,560, 4,385,035, and 5,245,916. Although effective, these carriers require assembly of multiple parts, adding complexity to the overall process. Because these carriers have not been optimized for ease of use, there exists a need for optimized carriers for processing irregularly shaped and/or fragile containers, including, but not limited to, pouches, thin-walled cans, bottles, tubs, and other containers.
It has been common to sterilize canned foods and beverages in a rotary sterilizer, for example, using a sterilizer of the type shown in
The rotary valve 1204 itself has a feeder wheel 1212 that receives the cans 1206 from an in-feed conveyor 1214. The feeder wheel has circumferential pockets 1216 defined by outwardly extending fins 1218 that receive the cans 1206 between two adjacent fins and move the cans through the valve 1204 into registry with the cells or pockets 1211 of the reel 1202 formed by the angle members 1210. In this manner, the cans are loaded into the rotary sterilizer at a very high rate of speed.
When the cans 1206 are at the upper portion of the reel 1202, they are supported by the reel itself, but when the cans are traveling along the bottom portion of the reel 1202, the cans are supported by the outer shell 1208, and are pushed along the outer shell by the angle members 1210 located behind the cans, as shown in
Historically, cans, such as cans 1206, have been of substantially sturdy construction, with the rims or chines at the upper or lower edges of the cans extending beyond the outer surface of the can so as not to dent or otherwise damage the can outer surface during the agitating process as the cans roll along the outer shell, or at other times when the cans are in contact with other components of the sterilizer 1200, for example, during transfer of the cans from the conveyor 1214 to the rotary valve 1204, transfer from the rotary valve 1204 to the reel 1202, movement of the cans along the sterilizer and transfer of the cans from the sterilizer to an output mechanism for further processing. Typically after the sterilization has been completed, a paper label is applied to the exterior of the can.
Food processors desire to now manufacture cans with thinner or lighter gauge material. However, the use of such lighter gauge material causes the cans to be more easily damaged during processing in the rotary sterilizer. Also, it is desirable to be able to use cans with a lithographically applied label and/or design to the can exterior prior to the sterilization of the can contents. However, such lithographic finishes can easily be scratched or otherwise damaged during the rotary sterilization process.
Moreover, it is desirable to be able to sterilize cans with necked-in tops and bottoms, for example, cans of the type used for soft drinks, in a rotary sterilizer rather than in a batch-type retort. Rotary sterilizers have much higher throughput than do batch retorts. However, necked-in cans do not have chines that extend outwardly of the exterior body of the can that serve to help protect the can exterior during the rotary sterilization process. Thus, if such cans were utilized in conjunction with the rotary sterilizer, the lithographed exterior of such cans would be scratched or otherwise damaged during the rotary sterilization process.
In addition, it is now common to package numerous types of beverages and liquid foods in plastic or other types of bottles. To date, sterilization of such bottles has been limited to using a batch retort. It would be advantageous to be able to sterilize the contents of such bottles using a rotary sterilizer for increased throughput. However, many bottles do not have the structural integrity to withstand the relatively rough handling, high acceleration and deceleration speeds that would be experienced in a rotary sterilizer. Also, some bottles are not cylindrical, and thus would not roll correctly on the rotary shell 1208.
The present disclosure seeks to address the above shortcomings with respect to the use of a rotary sterilizer with, for example, thin gauge metallic cans, necked-in cans, cans with a lithographic exterior, as well as plastic or other bottles.

The pouch carrier 20 is preferably a one-piece assembly for easily receiving a pouch P without requiring assembly or disassembly. For example, the pouch carrier 20 does not have a clam shell structure, a tray assembly, or a capsule assembly, for enclosing a container on all sides after the container has been received by the carrier, as described in respective U.S. Pat. Nos. 5,245,916, 4,385,035, and 3,314,560 for previously developed technologies, the disclosures of which are hereby expressly incorporated by reference herein.

Referring to the cross-sectional view of the body portion 112 in
After pouches P have been received in the sleeves 110, the sleeves 110 may include a retention system to further retain the pouches P within the sleeves 110 and/or to more evenly distribute the pouch contents within the pouch P for more even pouch thickness distribution within the sleeve. Suitable retention systems are used to minimize pouch movement when the pouch carrier 100 moves to minimize scuffing or wrinkling of the pouches P. Minimizing pouch scuffing and wrinkling not only preserves pouch aesthetics, but also pouch integrity. Moreover, retention systems that provide more even pouch thickness distribution within the sleeve 110 will provide for more consistent heat transfer to the contents in the pouches P. As a one-piece assembly, suitable retention systems are designed so that they do not separate from the body portion 112 of the carrier 100.
With reference to
In the illustrated embodiment of
Of note, the opening 208 in the first end 202 of the body portion 212 is larger than the normally biased closed position to allow for loading of the pouch when the outer pouch wall 220 is in the opened position. Referring to

The carrier 300 may further include an adjustable stop (not shown) to limit the travel distance of the first sleeve wall 330 to the closed position. As a non-limiting example, the adjustable stop may be a bolt or threaded stud attached to the first sleeve wall 330 and passing through a hole 338 in the stationary wall 340. The adjustable stop may, for example, includes adjustable nuts which rest against the stationary wall 340 or at least one of the stationary brackets 334 to limit the travel distance of the second sleeve relative to the stationary wall 340 or at least one of the stationary brackets 334.

In the illustrated embodiment of
It should be appreciated that the position limiting device 442 may be made from a flat spring material, such that it is capable of bending or flexing when in either of the first and second sleeve positions (e.g., compare positioning of right side sleeve 410 with left side sleeve 410 in
Now looking to the left side sleeve 410, the second contact surface 448 of the position limiting device 442 engages with a lower outer surface of the substantially vertical wall 450 of the stationary surface 412. The transition from the first position (see right side sleeve 410) to the second position (see left side sleeve 410) is achieved by pulling the outer sleeve wall 420 outwardly (for example, using pulling device D to hook downwardly extending flange 426) from the first position to the second position. As the position limiting device 442 moves outwardly through hole 452, the second contact surface 448 engages with the lower outer surface of the substantially vertical wall 450 of the stationary surface 412. In the second position, the sleeve 410 will remain open for loading or unloading.
The second contact surface 448 in the illustrated embodiment, is shown as a catch or tab with a cam ramp surface that is configured to engage with a lower edge of slot 452. The cam ramp surface allows for the transition from the first position to the second position while minimizing the risk of the position limiting device 442 catching en route. To transition from the second position back to the first position, the position limiting device 442 is lifted upwards to disengage the second contact surface 448 from the lower outer surface of the substantially vertical wall 450 of the stationary surface 412.
In the illustrated embodiment, the second sleeve wall 420 is normally biased in the closed position, with the wall being biased to a tapered position, having a smaller nominal sleeve width Wt at the top of the sleeve than at the bottom of the sleeve Wb. The inventors have found that a sleeve having a tapering width (as shown narrower at the top Wt and wider at the bottom Wb) helps to maintain the pouch (not shown) in the sleeve. It should further be appreciated that the sleeve closed position can be designed and dimensioned (depending on the size and shape of the specific pouch to be received) to substantially evenly distribute the contents in the pouch by bearing against a substantial surface area of the pouch. Such substantially even distribution can provide for more even heat transfer to the contents in the pouch for predictable and repeatable thermal processing.

To close the open sleeve 610 on the left side of the drawing, the position limiter assembly 640 is pushed to the right until the contact surface 648 (shown as a pierced tab) disengages the lower inner surface of the substantially vertical wall 650 of the stationary surface 612 (for example, similar to the position shown on the rights side of the drawing, but in mirror image). Referring now to the closed sleeve 610 on the right side of the drawing, the contact surface 648 engages the lower inner surface of the substantially vertical wall 650 of the stationary surface 612, and the sleeve 610 is maintained in a closed position. To open the closed sleeve 610 on the right side of the drawing, the position limiter assembly 640 is pushed up to release the engagement of the contact surface 648 and the lower inner surface of the substantially vertical wall 650 of the stationary surface 612. The second sleeve wall 620 then moves outwardly toward the substantially vertical wall 650 to rest in an open position (for example, similar to the position shown on the left side of the drawing, but in mirror image).
It should be appreciated that the carriers described herein are designed with robust position limiting devices, such that the carriers will remain in either of their designated open or closed positions as they travel through handling and processing shocks. Moreover, it should be appreciated that the carriers may be designed to have one or more position limiting assemblies that are capable of stopping in more than two (e.g., open and closed) positions. For example, the carriers may have different open positions designed for different sized pouches. Although the embodiments described herein generally include biasing members (such as compression springs or leaf springs), it should be appreciated that carriers without biasing members are also within the scope of the present disclosure.

During pouch loading, the pouch carrier 1100 is opened to receive first and second pouches P. The pockets 1154 and 1156 are shaped to constrain pouch motion, and in that regard, may be specifically designed for certain kinds of pouches or generally designed to constrain the motion of most pouches. After the pouches P have been loaded, the doors 1162 and 1164 are closed to snugly fit over the pouches P and constrain pouch motion. After the pouches have been loaded, at least one of the first and second portions 1150 and 1152 is rotated around hinge 1160 to latch together with latch 1166 and form a cylinder.
In addition to sleeve retention systems, as described above, sleeve cross-sectional shape may also assist with pouch retention to minimize movement of the pouch P within the sleeve and to more evenly distribute the contents of the pouch P throughout the entire pouch P. Referring to

It should be appreciated that the rotary systems may have an agitating reel (see
Referring now to
With canned food, agitation may be desirable for certain food types, for example, milk and other low-viscosity foods. With other fragile foods, for example, lima beans, agitation may not be desired because it may cause the beans to become broken or damaged. The advantage of using a non-agitating rotary sterilizer with the many embodiments of pouch carriers described herein is that agitation is minimized, which in turn minimizes scuffing and wrinkling of the carried pouches P. Therefore, in accordance with methods of the present disclosure for processing pouches in rotary sterilizers, pouches may be placed in cylindrical carriers and received in either agitating or non-agitating rotary systems, such as rotary sterilizers.

In addition to conveyors 1352 for support, the systems 1340 and 1350 may also include an optional alignment feature. Using an alignment feature, the carrier must be rotated or otherwise indexed to a correct position for loading or unloading pouches. For example, using the geometry of the carrier, if the central box containing the sleeves is rectangular in shape, a carrier can thus be guided along conveyors such that the long side of the box is parallel to travel. The orientation of the pocket openings is thus known. In the illustrated embodiment of
At the appropriate time, the carriers 600 are acted upon to allow the pouches P contained in the sleeves to drop downwardly from the sleeves (largely by gravity). Referring to
The pouches P will travel between the two supporting conveyors 1352 downwards onto appropriate chutes 1356 or take-away conveyors (see, e.g.,
Referring to
As another non-limiting example, the carriers may include “sleeves up” feature for determining if the carrier is correctly oriented for loading or unloading: sleeves upward, or downward, as required. For example, the pocket openings can be sensed using eddy current proximity sensors, magnetic sensors, or other appropriate sensors, and appropriate action can be taken to remove incorrectly oriented carriers.
It should be appreciated that the carrier unloading processes of
In accordance with these processes, carriers (as described above) can be unloaded after processing by rotating or otherwise orienting the carriers with the openings of the sleeves directed downwards, and aligning the carrier so that the long side of the sleeve is, for example, parallel to the path of travel along a conveyor. Likewise, carriers can be loaded by orienting the carriers with the sleeves upwards, aligning the carrier so that the long side of the sleeve is, for example, parallel to the path of travel along a conveyor.

The design generally includes a shaped area 1910 in the bottom of the carrier 1900 for mating with the contoured bottom end of a typical two-piece can, and plastic tabs 1920 at the upper end for mating with the seam chines or other geometry on the top end of a typical can. The points of contact are therefore on the top and bottom ends of the can, to prevent rubbing, denting, or other damage to the seam chines and the outer cylindrical wall of the can. This carrier 1900 can also be used with a two-piece can, can loaded top-end first; with three-piece cans having either end being captured by plastic tabs; or with plastic bottles having tabs designed to capture an appropriate feature on the bottle.

As shown in
It will be appreciated that by constructing the carrier 2200 with appropriate material, exhibiting sufficient flexibility, the staves 2228 of the body 2224 are capable of pressing against the can's exterior surface to hold the can securely in place within the carrier. To this end, the nominal interior diameter of the body section 2224 carrier is preferably smaller than the outer diameter of the container C to be held. In this regard, the carrier can be constructed from materials such as PEEK and PVDF.
It also will be appreciated that the overall size of the carrier, including the diameter of the rims 2222, is selected so as to be compatible with the rotary sterilizer to be utilized, and also to accommodate cans and bottles of a desired diameter and length. By utilizing the carrier 2200, containers C are held securely in place while being processed in a rotary sterilizer. During the processing, the containers do not contact the surfaces of the rotary sterilizer, and thus the containers are protected from scraping, scratches, or otherwise being damaged.
The carrier 2200 can be designed to apply a substantially uniform load or force on the container C along substantially the entire length of the staves 2228. This can be accomplished in various manners. For example, the thickness of the stave can be varied along its length. Specifically, the staves can be of thicker construction along the cylindrical portion of the carrier than at the location 2225 that the staves intersect the rims. This increases the rigidity of the staves in the thickened sections so as to enable the staves to apply a substantially uniform load against a can along the thickened portion of the staves. In this regard, see for example,
Alternatively, ridges can be formed along the interior of the staves to press against the can body. Such ridges can stand out from the interior of the staves a greater distance toward the longitudinal center of the carrier body 2224. As such, a substantially uniform pressure is imposed on the can substantially the entire length of the staves. Also, the ridges allow more access of the thermal process fluid to the can surface. In this regard, see
While the amount of the load applied to the cans can vary, it is desirable that the force applied to the can by the body be sufficient to substantially prevent the can from becoming unloaded from any staves during the sterilization process, including during the rolling of the carrier along the exterior shell of the rotary sterilizer and during transfer of the cans onto and out of the sterilizer. Thus, the required load applied to the can will vary with respect to the size of the can, including the diameter and length of the can.
For ease of loading and unloading, it is desirable that the carriers 2200 be symmetrical end-to-end. However, it is possible to construct a carrier so as to prevent a can from disengaging from at least one end of the carrier. In this regard, see for example
As discussed above, container C can be inserted into and removed from carrier 2200 by simply pressing the cans into the carriers, it is also possible to design the carriers so that an axial load may be applied against the underside of the rims 2222, thereby to pull the rims away from each other, longitudinally of the carrier 2200, which in turn will cause the staves 2228 to straighten relative to their attachment locations to the rims, and thus increase the internal diameter of the carrier so that the container can be easily slid into or out of the carrier. This method of loading and unloading the carrier may be needed if the sliding of the can into the carrier would cause the staves to scratch or otherwise damage the finish, including lithography, applied to the can exterior.
A further embodiment to the present disclosure is illustrated in
In carrier 2500 the staves 2528 are thickened in their exterior along sections 2532, thereby adding rigidity to the staves. The thickened portions 2532 of the staves extend along the cylindrical portion of the carrier body 2524. The added thickness causes each of the staves in cross-section to be generally rectangular in shape with the apex of the cross-section extending radially outwardly relative to the longitudinal center of the carrier 2500. The added material or thickness to the staves 2528 along exterior sections 2532 causes these portions of the staves to be more rigid than without such increased thickness. As a consequence, a relatively large and relatively uniform load can be applied to the exterior of a container being held.
Moreover, projections or bumps 2530 extend inwardly from the end portions of selected staves 2528. As noted above, such projections can serve to keep the container from sliding out of the carrier during processing. In addition, the carrier 2500 includes tabs 2534 that extend radially inwardly from the ends of the staves 2528 opposite to the location of the projections 2530. The tabs 2534 extend diagonally from the staves and then curve or otherwise extend transversely inwardly relative to the length of the staves so as to form shoulders or abutments to bear against the end portions of cans carried by the carrier 2200.
A further embodiment of the present disclosure is illustrated in
Also in carriers 3400 and 3500, the staves 3428 and 3528 are thickened in the inward side of the staves, thereby to define inwardly created ribs 3433 and 3533, respectively.
In each of the carriers 3400, 3500, 3600, and 3700, circular enlargements 3437, 3537, 3637, and 3737 are formed at the ends of the respective slots 3426, 3526, 3626, and 3726. In carriers 3400 and 3500, the ends of slots 3426 and 3526 flare out to tangentially intersect with the enlargements 3437 and 3537. Further, in carriers 3600 and 3700, additional slots 3640 and 3740 are formed at the intersections 3625 and 3725 of the staves 3628 and 3728 with corresponding rim portions 3622 and 3722. These slots 3640 and 3740 result in the ends of the staves 3628 and 3728 intersecting the rim portions 3622 and 3722 via relatively narrow strips 3644 and 3744. The purpose of such slots is to control the stresses introduced into strips 3644, 3744, and thus also the stress in the connector sections 3625 and 3725 during loading and unloading of container C. In carrier 3600, the slots 3640 are generally in the shape of an elongated triangle, with the apex of the triangle adjacent the rim 3622 and the base of the triangle located toward the stave 3628. The slots 3740 of carrier 3700 are similar in shape to the slots 3640 but extend a further distance along the stave 3728 than in the carrier 3600.
The carrier 3500 further differs from carriers 3400, 3600 and 3700 in that pairs of projections 3530 are formed at the ends of the interiors of the staves 3528. In addition, shallow longitudinal grooves 3542 extend along the interior of the staves 3528. These grooves can assist in reducing a potential “hydroplaning” type effect between the interior surface of the sleeves and the exterior of container C, causing container C to slip out of the carrier 3500.

In a manner similar to carrier 3500, the carrier 3900 includes a plurality of projections 3930 formed at the ends of the staves 3928 at the inside surfaces thereof. Also in a manner similar to holder carrier 3500, shallow grooves 3942 extend longitudinally along the inside surface of the staves 3928. Also similarly to carrier 3500, the exterior of the staves 3928 in carrier 3900 are thickened relatively uniformly in the outward direction of the staves, thereby adding rigidity to the longitudinal sections of the staves.
Features such as curved protrusions or ramps 4130 can be formed at the end portions of the body 4124 to hold the container C within the carrier 4100, see
Although not shown, slots can be formed in the body 4024 to facilitate heat transfer between the medium in the rotary sterilizer and the contents of the container C. Such slots can take many different forms. For example, the slots may extend along the length of the body in a manner similar to, for example, slots 2226, shown in
With respect to end plug 4356, such end plug also is snugly receivable within the body 4324 opposite to the location of the end plug 4357. The end plug 4356 includes a cylindrical section that closely fits within the inside diameter of the body 4324. A plurality of formed tabs 4330 project from the cylindrical section into the body 4324. The tabs are curved or rounded to present a generally convex protrusion or detent toward the interior of the body 4324. The tabs 4330 are configured to flex outwardly when a container, such as container C, is either inserted into the carrier by simply pressing the container into the sleeve 4324 or when removing the container C by pushing the container outwardly past the interior of the plug 4356. In this manner, the tabs 4330 operate in a manner similar to other tabs described above, including tabs 4230, 4130, and 1920 described above to retain the container C within the carrier 4300. As will be appreciated, the center of the plug 4356 is substantially open to allow circulation of heating fluid through the carrier 4300.
It also will be appreciated that, as with end plug 4357, the end plug 4356 can be replaced with an end plug of a different configuration so as to accommodate containers C of different sizes and shapes, including different lengths and different diameters, while utilizing the same exterior sleeve 4324, thereby resulting in economies of manufacture and also reducing the number of container sleeves needed while still being able to process containers of different shapes and sizes.
Openings or holes can be formed in the body portion 4324 to facilitate heat transfer with the contents of the container C. The body 4324 can be formed from a durable material, such as a high strength plastic or metal. The end plugs 4356 and 4357 can be constructed from a softer, more flexible, material such as a high strength plastic or metal. Also, to retain the end plugs 4356 and 4357 within the body 4324, indentations 4358 can be formed in the exterior of the body 4324 and corresponding protrusions, bumps, or similar features 4360 can be formed to project outwardly from the cylindrical sections of the end plugs to mate with the indentations 4358. Of course, numerous systems can be used to retain the plugs 4356 and 4357 within the body 4324. For example, a shallow groove may be formed around the interior of the end plugs 4356 and 4357, and corresponding ridges, series of bumps, or other protrusions may be formed on the exterior of the body 4324 to engage with the groove formed in the plugs 4356 and 4357.
As with carriers 4100 and 4200, slots can be formed in the body 4324 to facilitate heat transfer with the contents of the container C. Also, rather than utilizing slots, holes, perforations, or other through openings can be formed in the body 4324 to facilitate heat transfer with the contents of the container C.
As can be appreciated, the load placed on the container C by the bristles 4590 can be a function of the density or number of bristles as well as the length of the bristles, the stiffness of the bristles, etc. Moreover, the physical characteristics of the bristles can differ along the length of the interior of the liner 4464. For example, the bristles 4590 located near the ends of the inner liner 4564 can be of stiffer construction, of longer length and/or of greater density than in the remainder of the inner liner 4564. In this manner, the bristles 4590 at the ends of the inner liner 4564 can serve to help prevent longitudinal movement of a container C when disposed within the carrier 4500.
Also, as in carrier 4400, the outer cylindrical portion 4562 can include chines 4522 at its ends to facilitate the rolling of the carrier 4500 within the rotary sterilizer as described above. Also, as in the other carriers described above, slots or other openings can be formed in the body portion 4524 for facilitating the heat transfer to or from the contents of the container C held by the carrier 4500.
As shown in
Next,
The end cap assemblies 4880 are formed from an outer housing, shell or skin 4882 of substantially high strength rugged material, such as metal or a high strength plastic. Each housing 4882 includes a cylindrical section 4882A and an end wall 4282B disposed across one end of the cylindrical section.
A circular end insert 4883 and a cylindrical liner insert 4884 are snugly disposed within the housing 4882 to securely receive the container C therein. The end insert 4883 and liner 4884 can be formed from a material that may be compressible, deformable, elastic, etc., so as to receive the container C, and then securely hold the container C in place. As with the other carriers disclosed above, such as in
Next,
One difference between carrier 5000 and carriers 4800 and 4900 is that the interior of the insert 5084 of the end cap assemblies 5080 includes a plurality of inwardly extending fingers or bristles 5090. The bristles 5090 can be similar to bristles 4590, described above, or can be of a different construction consisting of a relatively fewer number of individual deformable fingers. Other than with the utilization of the bristles or fingers 5090, the construction of the end cap assemblies 5080 can be very similar to the construction of end cap assemblies 4880 and 4980, described above.
A further embodiment of the present disclosure is illustrated in
From the rim portion 5322, the end caps 5380 taper inwardly to define a bevel. This reduced diameter thickness of the end caps 5380 enables the end caps to be expandable to engage over the outside diameter of container C, while still applying sufficient compressive force on the container to securely retain the container in engagement with the end caps 5280.
A further embodiment of the present disclosure is illustrated in
Referring to
Although the carrier 5500 is illustrated as composed of eight separate segments, the carrier 5500 can be composed of a different number of segments, from a minimum of two to a number greater than shown in
As shown in
While several embodiments of the disclosure have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the present invention. In this regard, carriers, such as those described and depicted above, can be adapted to hold containers, such as cans and bottles, that are other than of a cylindrical shape, for example, cans and bottles that may be square, hexagonal or octagonal or elliptical in cross-section, and/or smaller in diameter at one end, for example if the container includes a necked-down end portion. In this regard, the body or sleeve portion of the carrier can be shaped to match the cross-sectional shape of the cans or bottles. Also, if the carrier includes circular rims, the end sections of the body or sleeve can be configured to transition the body to the circular rims. In this manner, the carrier is capable of easily rolling along the outer shell of the rotary sterilizer, or along other components of the sterilizer during the sterilization process.
Also, the number of staves, and thus, a corresponding number of slots, may be varied. Further, although the slots and staves are shown as equally spaced around the carrier body, that is not required. Rather, the spacing of the slots and staves can be other than uniformly about the carrier body. Also, the shape of the staves and slots illustrated and described above are only illustrative. The staves and slots can be of other various shapes.
Referring to
The interior of the body 6002 is shown as being cylindrical in shape and sized to receive the container C with clearance between the exterior of the container and the interior of the body. Of course, the interior of the body can be other than cylindrical in shape, especially if the body is molded from plastic or other moldable or formable material. However, if the body is fabricated from cylindrical material stock, then the interior of the body can simply match the exterior. Regardless, the body 6002 can be formed from a durable material, such as a high strength plastic or metal.
As can be seen in
In addition to body 6002, carrier 6000 also includes a retention system 6004 disposed within the body 6002. In the depicted embodiment, the retention system 6004 includes an insert 6008 that is secured within a first open end of the body 6002 for retaining a first end of the container C, and a plurality of flexible fingers 6006 extending from the insert 6008 along a length of the body 6002 for retaining a second opposite end of the container C.
Referring to
The insert 6008 may be at least temporarily secured within the body 6002 in any suitable manner. For instance, the insert 6008 may be spot or plug welded to the body 6002. In the alternative, the insert 6008 may be secured within the body 6002 through a shrink fit process. As an example, with the body 6002 heated (expanded) and the insert 6008 cooled (shrunk), the body 6002 and the insert 6008 are mated together and the temperature is equalized to define an interference fit therebetween. As yet another alternative, the insert 6008 may be snugly received within the body 6002 to define a friction fit therebetween. In such an alternative embodiment, the insert 6008 can be constructed from a softer, more flexible, material such as a high strength plastic or metal. Also, to help retain the insert 6008 within the body 6002, indentations, grooves, etc., may be formed on one of the exterior surface of the insert 6008 and the interior surface of the body 6002, and correspondingly-shaped features such as protrusions, bumps, etc., can be formed on the other of the exterior surface of the insert 6008 and the interior surface of the body 6002. Of course, numerous systems can be used to retain the insert 6008 within the body 6002. Moreover, it should be appreciated that the insert 6008 may instead be molded into or otherwise formed with the body itself.
As can be best seen by referring to
As noted above, the insert 6008 is configured to retain a first end of the container C within the body 6002 when the insert 6008 is secured within a first open end of the body 6002. In that regard, an annular shoulder 6018 is defined on the interior of the insert 6008 for receiving and retaining the first end of the container C. The annular shoulder 6018 surrounds the central opening 6014 and is defined between the inwardly sloped interior of the wall section 6010 and the transverse end section 6012. The annular shoulder 6018 is shaped to substantially correspond to and receive the first end of the container C.
In the illustrated embodiment, the container C is a 2-piece can, such as an aluminum can having a generally cylindrical body B and an upper annular rim R defined by a cover O secured to the body B through double seaming technology or the like. The annular shoulder 6018 is configured to capture and retain the upper annular rim R of the container. More specifically, the inner diameter of the annular shoulder 6018 is substantially the same size as the outer diameter of the upper annular rim R. In other words, there is a close tolerance between the insert 6008 and the upper annular rim R. The close tolerance between the inner diameter of the annular shoulder 6018 and the outer diameter of the upper annular rim R helps to distribute impact stresses on the carrier 6000.
Moreover, with the insert 6008 engaging the entire upper annular rim R with the smooth, continuous interior annular shoulder 6018, any damage to the rim R during processing is minimized. In other words, the insert 6008 does not damage (and protects) the upper annular rim R of the container C when engaged therewith. As can be appreciated by one of ordinary skill, a 2-piece can or similar container having a scratched or damaged upper rim is not desired because it is aesthetically unpleasant to a consumer. Accordingly, the insert 6008 helps prevent any damage to the upper end of the container during processing.
It should be appreciated that the interior of the insert 6008 may instead be any suitable shape to correspond to a first end of any suitable container. For instance, the insert 6008 may instead be shaped on its interior to correspond to a 3-piece can, a bottle-necked container, etc.
The insert 6008 is made from a suitable material to help distribute impact stresses on the carrier 6000 and minimize damage to the upper annular rim R during processing. For instance, the insert 6008 may be made from stainless steel or another high strength and heat tolerant metal or plastic.
The flexible fingers 6006 of the retention system 6004 configured to retain a second end of the container C within the body 6002 will now be described in detail. As can best be seen by referring to
The elongated section 6020 tapers in width or otherwise becomes more deformable near its distal end for passing over or removably retaining a container C between the plurality of fingers 6006. However, it should be appreciated that the elongated section 6020 may instead decrease in thickness or otherwise change in material gauge to define a sufficient amount of deformability or flexibility in the distal portions of the elongated section 6020. As such, the elongated section 6020 may be deformed outwardly away from the central axis 6024 and a container C may be passed upwardly between the plurality of fingers 6006 toward the insert 6008 for disposing the container C within the carrier 6000.
More specifically, the fingers 6006 may be moved between a first position, wherein the fingers 6006 are spaced from the container C to receive the container into the body 6002, and a second position, wherein the fingers 6006 hold the container within the body. The elastic properties of the fingers 6006 bias the fingers 6006 toward the second position such that the fingers 6006 impose a force on the container C to retain the container within the body 6002.
Each finger 6006 includes at its distal end a tab portion 6028 that is configured to bear against a bottom portion of the container C when the container C is received between the fingers 6006 and within the upper interior portion of the insert 6008. The tab portion 6028 may be any suitable shape and configuration for appropriately bearing against a bottom portion of the container C for retaining the container C within the body 6002 without damaging the container C during processing.
In the depicted embodiment, the lower end of the container C (opposite the annular rim R) is enclosed and includes an inwardly and downwardly annular sloped end surface E terminating in an annular protrusion P, with both the annular sloped end surface E and the annular protrusion P substantially concentric about central axis 6024. The tab portion 6028 is substantially V-shaped in cross-section with the apex of the V extending toward the central axis 6024. In this manner, at least a portion of the annular sloped end surface E may bear against or rest against an upper portion 6030 of the V-shaped tab portion 6028 when disposed within the carrier 6000.
It should be appreciated that the tab portion 6028 may instead be any other suitable shape or configuration for bearing against another bottom portion of the container C or against the bottom portions of other various-shaped containers C. Moreover, it should be appreciated that the tab portion 6028 may be made from a different material than the elongated section 6006, such as a deformable or pliable material that will not scratch or damage the container C. In the alternative, the tab portion 6028 may be coated with or otherwise covered with a non-abrasive material, such as rubber.
The tab portions 6028 of the fingers 2006 are collectively configured to center the container C within the body 6002, as well as to substantially prevent any longitudinal or axial movement of the container C when positioned against the insert 6008. Moreover, the tab portions 6028 are positioned intermediate the end of the body 6002, such that the container C does not protrude from the body 6002 when retained therein by the fingers 6006.
The fingers 6006 can be constructed from spring steel or other material which allows the fingers 6006 to be flexible. In this manner, the fingers 6006 are retractable to allow the container C to be loaded into and out of the carrier 6000 without bearing against the container C during the loading and unloading process so as not to damage container C. Also, the spring steel construction causes the fingers 6006 to be resilient and bear against the container C once the retracting force is removed from the fingers 6006 and they are allowed to bear against the container C (when moving from the first to second position). It should be appreciated that the fingers 6006 can instead be constructed of other materials that provide other characteristics similar to spring steel, for example, a flexible plastic-based material. Moreover, as noted above with respect to the tab portions 6028, some or all portions of the fingers 6006 can be coated with a non-abrasive material, such as rubber. In this manner, any contact that the fingers 6006 have with the container C during the loading or unloading process minimizes any scratching or other damage to the container C.
The proximal end of the fingers 6006 is secured to the insert 6008 for defining the retention system 6004 that is disposable within the body 6002. The plurality of fingers 6006 are attached at their proximal ends to the insert 6008 through hardware members, such as screws, bolts, rivets, etc., which can extend through clearance holes form in the body 6002 (not labeled). It should be appreciated that the fingers 6006 may be secured to the insert 6008 in any other suitable manner, such as with adhesive, weldments, etc.
The fingers 6006 may be received within finger receiving cavities or recesses 6032 defined along the exterior surface of the insert 6008. In this manner, the overall shape of the combined finger 6006 and insert 6008 assembly is cylindrical for fitting within the body 6002. Each recess 6032 extends longitudinally along the cylindrical wall section 6010 and has a predetermined depth for receiving a finger 6006 in a manner so that the finger 6006 does not obstruct the insertion of the retention system 6004 within the body 6002.
The recesses 6032 are spaced equidistant around the circumference of the insert 6008 to space the fingers 6006 substantially equally around the insert 6008 and around the body 6002 when received therein. In the depicted embodiment, the insert 6008 includes three recesses 6032 for receiving three fingers 6006. However, it should be appreciated that any other suitable number of recesses 6032 and fingers 6006 may instead be used, such as two, four, five, etc. For instance, less than or more than three fingers 6006 may be used if the container C is of a shape other than cylindrical. For example, if the container is generally square-shaped, four fingers 6006 may be utilized. Also, if the fingers 6006 including the tab portion 6028 are constructed differently from that described above, it is possible that even a singular finger or tab structure may be utilized with the carrier 6000.
As can be seen in
With the insert 6008 received within the body 6002, the fingers 6006 extend longitudinally along the length of the body 6002 and slightly inwardly toward the central axis 6024. As shown in
With the retention system 6004 (defined by the insert 6008 and the fingers 6006) disposed within the body 6002, the fingers 6006 may be retracted away from the central axis 6024 into the first position to load or unload a container C from within the retention system 6004. In that regard, the body 6002 includes a plurality of openings 6036 that correspond in position to a majority of the length of the fingers 6006. Specifically in the embodiment depicted, the body 6002 includes three openings corresponding to the three fingers 6006. The openings 6036 extend along a portion of the length of the body 6002 to provide access to the corresponding fingers 6006. Through the openings 6036, the fingers 6006 may be retracted away from the central axis 6024 into the first position to load or unload the container C therefrom. A retractor or other device may be used to retract the fingers 6006 away from the central axis 6024 for the loading and unloading process.
Referring to
The cylindrical portion 7006 has a generally cylindrical exterior and interior, and an inside diameter larger than the container C′. More specifically, the interior of the body 7002 is shown as being cylindrical in shape and sized to receive the container C′ with clearance between the exterior of the container and the interior of the body. Of course, the interior of the body can be other than cylindrical in shape, especially if the body is molded from plastic or other moldable or formable material. However, if the body is fabricated from cylindrical material stock, then the interior of the body can simply match the exterior. Regardless, the body 7002 can be formed from a durable material, such as a high strength plastic or metal. Moreover, as with other carriers (such as, for example, carriers 4100 and 4200), slots, holes, or other types of openings can be formed in the body 7002 to facilitate heat transfer with the contents of the container C′.
Although not shown, the body 7002 can include rims or chines, for example, at the ends of the body, to add strength to the body as well as provide contact surfaces about which the body may roll. Also, if the exterior of the body is not cylindrical in shape, circular rims or chines provide a surface about which the body can roll.
Referring to
The first end portion 7010 of the body 7002 is generally configured to capture and retain the upper annular rim R′ of the 2-piece can C′. In that regard, an interior annular shoulder 7018 is defined between the cylindrical portion 7006 and the first end portion 7010. The interior annular shoulder 7018 is configured to engage and the upper corner of the annular rim R′ defined by the outer surface OS' of the upper annular rim R′ and the upper surface US' of the upper annular rim R′. In this manner, the upper and outer surfaces US' and OS' of the upper annular rim R′ are substantially prevented from any damage during processing.
As can be appreciated and as noted above with respect to carrier 6000, a 2-piece can or a similar container having a scratched or damaged upper rim is not desired because it is aesthetically unpleasant to a consumer. Moreover, the upper and outer surfaces US' and OS' of the upper annular rim R′ are highly visible to the consumer when consuming the contents of the container C′. Accordingly, by instead engaging the upper corner of the upper annular rim R′, damage to the upper end of the container is minimized during processing.
The first end portion 7010 of the body 7002 is also generally configured to provide support for the carrier 7000 as it is processed in the sterilizer. As noted above, chines or rims may be provided on the body 7002 to provide additional support for the body as it travels through the sterilizer. In that same regard, the first end portion 7010 includes a folded-over edge 7020 that helps provide stability and support to the body 7002 as it is processed. More specifically, the folded-over edge 7020 helps provide axial and radial impact resistance to the first end of the carrier 7000 as it travels through the sterilizer.
The second end portion 7014 of the body 7002 will now be described in detail. The second end portion 7014 of the body 7002 is configured to receive a retention system for engaging the second end of the container C′ and retaining the container C′ within the body 7002. In the depicted embodiment, the second end portion 7014 is generally configured to removably receive a retaining member, such as a clip 7030 that is engageable with and bears against the bottom of the container C′ when received within the carrier 7000. In that regard, an interior annular groove 7034 is defined in the second end portion 7014 that is configured to removably receive the clip 7030. The annular groove 7034 is substantially concentric with a center longitudinal axis 7024 of the body 7002 and positioned is axially along the body 7002 (on the second end portion 7014) such that the clip 7030 may engage the annular protrusion P′ on the bottom of the container C′. The annular groove 7034 may be any suitable cross-sectional shape and size to help ease the clip 7030 into and out of the groove 7034.
The clip 7030, which can best be seen in
The clip 7030 is made from an elastic material having a suitable yield strength such that it may be deformed (decreased in diameter) for moving into and out of the annular groove 7034 and released back toward its original state for being retained within the annular groove 7034. Any suitable material may be used, such as spring steel. It should be appreciated that the clip 7030 can instead be constructed of other materials that provide other characteristics similar to spring steel, for example, a flexible plastic-based material. Moreover, some or all portions of the clip 7030 can be coated with a non-abrasive material, such as rubber, to help prevent any scratching or other damage to the container C′ when engaged by the clip 7030.
The clip 7030 also includes a plurality of radial projections 7044 extending from the clip body 7038 toward the center of the clip. The radial projections 7044 are co-planar with the clip body 7038 and are of a suitable length such that they engage the annular protrusion P′ of the container C′ when the container C′ is disposed within the carrier body 7002 and the clip 7030 is disposed within the annular groove 7034. Moreover, the radial projections 7044 are somewhat pointed or taper in width as they extend radially inwardly so as to minimize the contact area with the annular protrusion P′. It should be appreciated, however, that the radial projections 7044 may instead extend from the clip body 7038 at an angle and may be any suitable shape and size to appropriately engage a bottom portion of a container. For instance, if the container is a bottle or another type of container different from a 2-piece can, the shape, size, location, etc., of the radial projections 7044 may be adjusted accordingly.
In the depicted embodiment, the clip 7030 includes five radial projections 7044 spaced substantially evenly around the circumference of the clip body 7038. However, any suitable number of radial projections 7044 and any suitable spacing between projections may be used.
It can be appreciated that by using radial projections 7044 to engage the annular protrusion P′, rather than by extending the clip body 7038 radially inwardly to engage the annular protrusion P′, the clip 7030 remains sufficiently flexible to be deformed into engagement with the annular groove 7034. Moreover, the radial projections 7044 provide less contact with the annular protrusion P′ that would otherwise occur if the entire clip body 7038 engaged the annular protrusion P′. Accordingly, any scratching or damage caused by the contact is minimized.
In use, the clip 7030 is secured within the annular groove 7034 after the container C′ is disposed within the body 7002 such that the top of the container, and specifically, the annular rim R′ is engaged with the interior of the first end portion 7010. With the container C′ secured within the carrier 7000 in this manner, the more visible annular rim R′ is not scratched or damaged, even minimally, by the clip 7030. Rather, the container C′ can be positioned within the carrier 7000 such that the more significant contact occurs on the bottom of the container C′. Moreover, as with other carriers, the body 7002 is sufficiently large in diameter, and the container C′ is positioned within the carrier such that the sides of the container C′ are not touched by the body 7002. Accordingly, the carrier 7000 is suitable for transporting a container through a sterilizer while minimizing any scratching or other damage to the container during processing.

The cylindrical portion 7106 has a generally cylindrical exterior and interior, and an inside diameter larger than the container C″. More specifically, the interior of the body 7102 is shown as being cylindrical in shape and sized to receive the container C″ with clearance between the exterior of the container and the interior of the body. Of course, the interior of the body can be other than cylindrical in shape, especially if the body is molded from plastic or other moldable or formable material. However, if the body is fabricated from cylindrical material stock, then the interior of the body can simply match the exterior. Regardless, the body 7102 can be formed from a durable material, such as a high strength plastic or metal. Moreover, as with other carriers (such as, for example, carriers 4100 and 4200), slots, holes, or other types of openings can be formed in the body 7102 to facilitate heat transfer with the contents of the container C″.
Although not shown, the body 7102 can include rims or chines, for example, at the ends of the body, to add strength to the body as well as provide contact surfaces about which the body may roll. Also, if the exterior of the body is not cylindrical in shape, circular rims or chines provide surface about which the body can roll.
Referring to
The second end portion 7114 of the body 7102 is generally configured to capture and retain the container C″ in a centrally located position (related to a central axis 7124) within the body. More specifically, the second end portion 7114 of the body 7102 is shaped to receive the bottom of the container C″ defined by the inwardly and downwardly annular sloped end surface E″ and the annular protrusion P″. In that regard, the second end portion 7114 is generally shaped to match the shape of the bottom of the container C″. In this manner, the second end portion 7114 secures and retains the container C″ in the centrally located position. A central bottom opening 7128 may also be defined in the second end portion 7114 to help facilitate heat transfer with the contents of the container C″.
The first end portion 7110 of the body 7102 will now be described in detail. The first end portion 7110 is generally configured to removably receive a retaining member, such as a clip 7130, for bearing against the first end of the container C″ when received within the carrier 7100. In that regard, the first end portion 7110 includes a tapered annular end 7034 that is configured to position the clip 7130 against the first end of the container C″. More specifically, the tapered annular end 7134 decreases the diameter of the body 7102 at its first or upper end, such that when a clip 7130 having an outer diameter larger than the tapered annular end 7134 is disposed in the first end of the body, the clip 7130 is retained in is axial position within the body 7102. In other words, the clip 7130 is secured in its position between the first end of the container C″ and the tapered annular end 7134 of the body. The tapered annular end 7134 surrounds a top central opening 7136 to help facilitate heat transfer with the contents of the container C″.
The clip 7130 has a clip body 7138 that is generally C-shaped and has a circular outer diameter that is somewhat larger than the interior diameter of the body 7102 (and the tapered annular end 7134) in an undeformed state. With the clip body 7138 being C-shaped, the body includes a gap 7140 that may be decreased or increased in size to decrease or increase the size of the outer diameter of the clip body 7138. In other words, the clip 7130 may be squeezed to decrease the gap 7140 (decreasing the clip outer diameter) for moving the clip 7130 into and out of the body 7102. When received within the body 7102, the clip 7130 may be released back toward its original shape and size. With the interior diameter of the body 7102 (and the tapered annular end 7134) being smaller than the outer diameter of the clip body 7138 in an undeformed state, the clip 7130 is retained within the body 7102 when released. Moreover, when positioned against the container C″, the clip 7130 is retained in its axial position between the container C″ and the tapered annular end 7134.
The clip 7130 is made from an elastic material having a suitable yield strength such that it may be deformed (decreased in diameter) for moving into and out of the body 7102 and released back toward its original state for being retained within the body 7102. Any suitable material may be used, such as spring steel. It should be appreciated that the clip 7130 can instead be constructed of other materials that provide other characteristics similar to spring steel, for example, a flexible plastic-based material. Moreover, some or all portions of the clip 7130 can be coated with a non-abrasive material, such as rubber, to help prevent any scratching or other damage to the container C″ when engaged by the clip 7130.
Unlike clip 7030 shown in
In the depicted embodiment, the clip body 7138 extends toward the central axis 7124 a predetermined distance until it engages the upper surface US″ of the upper annular rim R″ of the container C″. The clip body 7138 terminates in a substantially transverse annular flange 7144 extending upwardly from the clip body 7138. The annular flange 7144 is graspable by the user (or by an automated or semi-automated tool or equipment) to deform the clip 7130 for moving it into and out of the body 7102. In that regard, the clip 7130 may instead include any other mechanism for grasping and deforming the clip.
In use, the clip 7130 is secured within the first end portion 7110 of the body 7102 after the container C″ is disposed within the body 7102 such that the bottom of the container, and specifically, the annular sloped end surface E″ and the annular protrusion P″ are engaged with the interior of the second end portion 7114. With the container C″ secured within the carrier 7100 in this manner, the clip 7130 may be disposed within the body 7102 such that it is positioned axially between the upper annular rim R″ of the container and the tapered annular end 7134. The clip 7130 therefore secures the container C″ within the body 7102 of the carrier 7100 and prevents the container from moving within the carrier during processing.
Moreover, as with other carriers, the body 7102 is sufficiently large in diameter, and the container C″ is positioned within the carrier such that the sides of the container C″ are not touched by the body 7102. Accordingly, the carrier 7100 is suitable for transporting a container through a sterilizer while minimizing any scratching or other damage to the sides of the container during processing.

The cylindrical portion 7206 has a generally cylindrical exterior and interior, and an inside diameter larger than the container Cm. More specifically, the interior of the body 7102 is shown as being cylindrical in shape and sized to receive the container C′″ with clearance between the exterior of the container and the interior of the body. Of course, the interior of the body can be other than cylindrical in shape, especially if the body is molded from plastic or other moldable or formable material. However, if the body is fabricated from cylindrical material stock, then the interior of the body can simply match the exterior. Regardless, the body 7102 can be formed from a durable material, such as a high strength plastic or metal. Moreover, as with other carriers (such as, for example, carriers 4100 and 4200), slots, holes, or other types of openings can be formed in the body 7202 to facilitate heat transfer with the contents of the container C′″.
Although not shown, the body 7202 can include rims or chines, for example, at the ends of the body, to add strength to the body as well as provide contact surfaces about which the body may roll. Also, if the exterior of the body is not cylindrical in shape, circular rims or chines provide surface about which the body can roll.
Referring to
The second end portion 7214 of the body 7202 is generally configured to capture and retain the container C′″ in a centrally located position (related to a central axis 7224) within the body. In that regard, the second end portion 7214 is substantially identical to the second end portion 7114 of carrier 7100. More specifically, the second end portion 7214 is shaped to receive the bottom of the container C′″ defined by the inwardly and downwardly annular sloped end surface E′″ and the annular protrusion P″. In that regard, the second end portion 7214 is generally shaped to match the shape of the bottom of the container C′″.
The first end portion 7210 of the body 7202 will now be described in detail. The first end portion 7210 is generally configured to removably receive a retaining member, such as a clip 7230, for bearing against the first end of the container C′″ when received within the carrier 7200. In that regard, the first end portion 7210 includes an interior annular groove 7234 that is concentric with the central axis 7224 and that is configured to position the clip 7230 against the first end of the container C′″. The annular groove 7234 may be any suitable cross-sectional shape and size to help ease the clip 7230 into and out of the groove 7234. The second end portion 7214 may have a substantially identical annular groove 7250 that defines an exterior rim to help facilitate rolling of the carrier 7200 on the exterior of the annular grooves 7234 and 7250.
The clip 7230, which can best be seen in
The clip 7230 also includes a plurality of radial projections 7248 extending from the clip body 7238 downwardly away from the center of the clip. The radial projections 7248 are configured to engage the interior annular groove 7234 of the first end portion 7210 to removably secure the clip 7230 therein. In that regard, the radial projections 7248 are deformable toward one another to temporarily decrease the overall diameter of the clip 7230 for easing the clip into and out of the interior annular groove 7234. In a non-deformed state, the overall diameter of the clip 7230 is larger than the diameter of the interior annular groove 7234 to secure the clip therein. Each radial projection 7248 may have a turned up or otherwise contoured distal edge to help ease the clip 7230 into and out of the annular groove 7234.
In the depicted embodiment, the clip 7230 includes twenty radial projections 7248 spaced substantially evenly around the circumference of the clip body 7238. However, any suitable number of radial projections 7248 and any suitable spacing between projections may be used.
The radial projections 7248, or optionally the entire clip 7230, is made from an elastic material having a suitable yield strength such that it may be deformed (decreased in diameter) for moving into and out of the annular groove 7234 and released back toward its original state for being retained within the annular groove 7234. Any suitable material may be used, such as spring steel. It should be appreciated that the clip 7230 can instead be constructed of other materials that provide other characteristics similar to spring steel, for example, a flexible plastic-based material. Moreover, some or all portions of the clip 7230 can be coated with a non-abrasive material, such as rubber, to help prevent any scratching or other damage to the container C′″ when engaged by the clip 7230.
In use, the clip 7230 is secured within the annular groove 7234 after the container C′″ is disposed within the body 7202 such that the bottom of the container, and specifically, the annular sloped end surface E′″ and the annular protrusion P″ are engaged with the interior of the second end portion 7214. With the container C′″ secured within the carrier 7200 in this manner, the clip 7230 may be disposed within the annular groove 7234 such that the clip body 7238 is positioned against the annular rim R′″. The clip 7230 therefore secures the container C′ within the body 7202 of the carrier 7200 and prevents the container from moving within the carrier during processing.
Moreover, as with other carriers, the body 7202 is sufficiently large in diameter, and the container C′″ is positioned within the carrier such that the sides of the container C′″ are not touched by the body 7202. Accordingly, the carrier 7200 is suitable for transporting a container through a sterilizer while minimizing any scratching or other damage to the sides of the container during processing.

With the clip bodies 7338 and 7438 being C-shaped, the bodies each include a gap 7340 and 7440, respectively, that may be decreased or increased in size to decrease or increase the size of the outer diameter of the clip body. When received within an annular groove, body, etc., the clip may be released back toward its original shape and size.
The clips 7330 and 7430 are made from an elastic material having a suitable yield strength such that it may be deformed (decreased in diameter) for moving into and out of an annular groove, body, etc., and released back toward its original state for being retained therein. Any suitable material may be used, such as spring steel. It should be appreciated that the clips 7330 and 7430 can instead be constructed of other materials that provide other characteristics similar to spring steel, for example, a flexible plastic-based material. Moreover, some or all portions of the clips 7330 and 7430 can be coated with a non-abrasive material, such as rubber, to help prevent any scratching or other damage to the container when engaged by the clip.
Each clip 7330 and 7430 includes a plurality of radial projections 7344 and 7444, respectively, extending from the clip body 7338 and 7438, respectively, toward the center of the clip. The radial projections 7344 and 7444 extend upwardly and downwardly from the clip bodies 7338 and 7438, respectively, in an alternating fashion. The radial projections 7344 and 7444 are also of a suitable length and contour to appropriately engage a desired first or second end of a container. For instance, one set of the upwardly or downwardly extending radial projections 7344 and 7444 may be configured to hook around and engage the annular rim R of a container C or the annular protrusion P of a container C. In that regard, the radial projections 7344 and 7444 may be suitably contoured to engage the container without substantially scratching or damaging the container during processing. The other set of the upwardly or downwardly extending radial projections 7344 and 7444 may be configured to be grasped by a user (or with a suitable tool) to deform the clips 7330 and 7430, respectively, for moving into and out of engagement with the carrier.

The carrier 8000 is illustrated as composed of a body 8002 having a length longer than the container C″, which is supported and carried by the body 8002. In some embodiments, the carrier 8000 may be configured to carry more than one container. In such an alternative embodiment, the body 8002 may be longer than the total combined length of the plurality of containers. The carrier 8000 may instead be arranged to carry multiple containers in any other suitable manner.
The body 8002 includes a cylindrical portion 8006 extending along a majority of the length of the body 8002, a first end portion 8010 defined at a first end of the cylindrical portion 8006, and a second end portion 8014 defined at a second end of the cylindrical portion 8006 opposite the first end portion 8010. First and second, or upper and lower openings 8036 and 8028 are defined in the first and second ends of the cylindrical portion 8006 for facilitating heat transfer with the contents of the container C″.
In the embodiment depicted in
The interior of the body can be other than cylindrical in shape to match the shape of the container, especially if the body is molded from plastic or another moldable or formable material. However, if the body is fabricated from cylindrical material stock, then the interior of the body can simply match the exterior. Regardless, the body 8002 can be formed from a durable material, such as a high-strength plastic or metal. Moreover, as with other carriers (such as, for example, carriers 4100 and 4200), slots, holes, or other types of openings can be formed in the body 8002 to facilitate heat transfer with the contents of the container C″.
The first and second end portions 8010 and 8014 are substantially identical; and therefore, only the first end portion 8010 will be described in detail. The first end portion 8010 is generally defined by an annular folded over rim extending radially outwardly from the upper or first end of the cylindrical portion 8006 of the body 8002. The annular folded over rim is generally U-shaped in cross-section, with the bottom portion of the U-shaped annular rim substantially transverse to the side portions and with curved junctures therebetween. The annular folded over rim of the first end portion 8010 provides a supportive cylindrical structure on which the carrier 8000 may roll. More specifically, the folded-over rim of the first end portion 8010 helps provide axial and radial impact resistance to the first end of the carrier 8000 as it travels through the sterilizer.
The second end portion 8014 includes an annular folded over rim that is substantially the same shape and size as the annular folded over rim of the first end portion 8010. In this manner, the carrier 8000 may roll evenly on the first and second end portions 8010 and 8014 with the cylindrical portion 8006 of the body 8002 remaining out of contact with any rolling surface. Also, if the exterior of the body 8002 is not cylindrical in shape, the circular first and second end portions 8010 and 8014 provide surface about which the body can roll. It should be appreciated that the first and second end portions 8010 and 8014 may instead be any other suitable shape or configuration to provide a suitable rolling surface for the carrier 8000.
Referring to
The diametric clearance between the exterior of the container X and the interior of the body 8102 may be up to about 0.50 inches, or any other suitable amount. With a gap defined between the exterior of the container X and the interior of the body 8102, the container X will necessarily shift within the carrier 8100 during processing. Accordingly, such a carrier embodiment is well suited for a rotary processor that defines a suitable pocket for retaining the container X within the carrier 8100 during processing.

The shapes and constructions of the carriers described and illustrated herein are only representative examples of the shapes that the carriers may take, in accordance with the present disclosure.
Moreover, it should be appreciated that reference to a first end, second end, upper end, bottom end, etc., of the container and/or the carrier or carrier body is for illustrative purposes only, and should not be seen as limiting. For example, any of the foregoing carriers may be modified to receive and hold a container in a manner inverted from what is shown.
In addition, the embodiments of the present disclosure have been described for use with rotary processing systems. It is to be appreciated that the carriers of the present disclosure also can be used with other types of thermal processing systems, including retorts having drums that may or may not rotate during the processing of food products or other non-food-related rotary processes.
Moreover, numerous of the embodiments of the present disclosure have been described and illustrated for use in conjunction with a container C or the like, in the form of a cylindrical can. However, the carriers of the present disclosure can be used in conjunction with numerous other types of containers, including cans or bottles or boxes that are cylindrical, spherical or polygonal in cross-sectional shape or even with containers in the form of pouches or envelopes.
Furthermore, numerous of the embodiments of the present disclosure have been described and illustrated for use with a single container. However, it should be appreciated that the carriers of the present disclosure may be adapted for carrying two or more containers (for instance, with the containers stacked upon one another).
