Thus, for example, any aspect may be combined with an aforementioned feature in accordance with the present invention without requiring any other aspect or feature.
One or more preferred embodiments of the present invention now will be described in detail with reference to the accompanying drawings, wherein like elements are referred to with like reference numerals.
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Additionally, as used herein, a “score line” is intended to mean an elongated area along which a fold is predisposed to form upon application of force. Within this broader context, a score line may be a generally linear area of weakness formed in a corrugated or non-corrugated panel along which the panel is predisposed to fold upon application of a force on the panel. A score line may be formed by way of example, and not limitation, by notching, scratching, incision, compression, perforation, physical deformation, or otherwise.
Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.
Turning now to the figures,
Each of the side panels 16,18 includes two attachment panels 17 extending therefrom that are each separated therefrom by a respective score line 15. In at least some implementations, each set of two score lines 15 and one score line 11 are segments of, and collective form, a single score line running the width of box cutout 10, just as score line 13 does.
Each of score lines 11,13,15 facilitates folding of the box cutout 10 along that score line. The box cutout 10 is configured such that the scores lines 11,15 facilitate transitioning of the box cutout 10 into a box configuration, and the score line 13 facilitates transitioning of the box configuration between different box configurations, namely, an expanded box configuration and a collapsed box configuration, as described in detail below.
Each of the attachment panels 17 can be folded upward and inward about a respective score line 15, as illustrated by the fold arrows in
The box cutout 10 is configured to allow the box cutout 10 to be transitioned to a collapsed box configuration as well, even after securing the front and back panels 12,14 to the attachment panels 17. This collapsing is enabled by both the score lines 13 bisecting the side panels 16,18, and by “major” score lines 19 of the bottom panel 20, which can perhaps best be seen in
The score lines 13 bisecting the side panels 16,18 allow the side panels to collapse inwards during collapsing of the box cutout 10, as illustrated by the arrows in
During collapsing, minor score lines 21 in the bottom panel 20, which are illustrated in the drawings and called out at least in part in
The box cutout 110 is similar to the box cutout 10, but is configured such that attachment panels 118 extend from the front and back panels 112,114 instead of from side panels 116. In this regard, side panels 116 are secured to attachment panels 118 to collectively form sides of a box when the box cutout 110 is transitioned to a box configuration.
Similar to the box cutout 10, the box cutout 110 also includes a score line 113 which bisects the bottom panel 120, and each of the side panels 116 extending therefrom. The box cutout 110 further similarly includes major score lines 119 and minor score lines 121 in the bottom panel 120.
The score line 113 which bisects the bottom panel 120 and each of the side panels 116, together with the major score lines 119, enable the bottom panel 120 and the side panels 116 to be collapsed via folding in a manner similar to that described above with respect to the box cutout 10.
It will be appreciated that each of the box cutout 10 and box cutout 110 can be transitioned to a fully formed but folded and collapsed configuration from an initial, flat, unfolded configuration without first being transitioned to a box configuration. For example, with regard to box cutout 110, top and bottom halves of the box cutout 110 can be folded together about the score line 113 which bisects the bottom panel 120 and each of the side panels 116 while the bottom panel 120 is collapsed downward as enabled by one or more of the major score lines 119. As the bottom panel 120 is folded about the score line 113 which bisects it and one or more of the major score lines 119, the center of each side panel 116 is preferably transitioned upward and inward as the side panel folds along the score line 113 which bisects it, as illustrated in
Previously or concurrently, the attachment panels 118 can be folded inward about the score lines 117. Consequently, as the box cutout 110 is folded in half about the score line 113 which bisects the bottom panel and the side panels 116, and about one or more of the bottom score lines 119, an outer face 128 of each of the attachment panels 118 extending from the top or bottom panel 112,114 comes into abutment with an inner face 126 of one of the side panels 116 extending from the bottom panel 120, as perhaps best seen with reference to
It will be appreciated that a similar—but not identical—process can be utilized with box cutout 10.
The box cutout 110 can be transitioned from the folded and collapsed configuration illustrated in
Unlike exemplary box cutout 10, exemplary box cutout 110 is further configured to be closed via a cover formed from integral cover portions 140 of the box cutout 110. The box cutout 110 includes cover score lines 142 that are configured to allow hinge portions 144,146 to be folded inward about the cover score lines 142 so as to allow the cover portions 140 of the box cutout 110 to fold down to form a cover for the box cutout 110 when it is in a box configuration, as illustrated in
Notably, the box cutout 10 and the box cutout 110 can both be transitioned from a flat or collapsed box configuration to an expanded box configuration and be used for storage without utilizing tape to secure either cutout in a box configuration. Further, the configuration of both box cutout 10 and box cutout 110 results in the box cutout, when in a box configuration, having reinforced double wall sides that are believed to be superior in stacking strength as compared to a conventional box with a single wall side.
In a preferred method of manufacturing a box, a box cutout, such as box cutout 110, is automatically transitioned from an initial, flat, unfolded configuration (such as that illustrated in
The machine 210 is configured to repeatedly drop down the bottom most box cutout 110 in the cutout receiving area 211 and push it forward so that it travels atop guide rails 215 (shown in FIG. 19) and engages drive wheels 212, as illustrated in
Preferably, a freely rotating wheel 213, i.e. a free wheel, is disposed above each drive wheel 212. Such free wheels 213 serve to, inter alia, minimize or preclude lifting of a box cutout 202 that is engaged and propelled by the drive wheels 212.
The machine 210 includes a first sensor or detector 214, preferably in the form of a laser detector, and one or more glue applicators 216. In operation, the first laser detector 214 detects the presence of a box cutout 202, and triggers application of glue to the box cutout 110 via the one or more glue applicators 216. The glue is preferably fast drying glue; however, it will be appreciated that the process need not pause in order for the glue to set, as the glued portions are properly disposed in abutting engagement when the cutout 110 is in the collapsed box configuration, thereby enabling the glue to set, if necessary or desired, in the collection area or pen the machine 210.
After glue application, the box cutout 110 continues to be driven forward by a second drive wheel 212 so as to position the box cutout 110 under a plunger 220, as illustrated in
The machine 210 includes a backstop 224, which is positioned relative to the plunger based on the dimensions of box cutouts 110 such that, when an end of a box cutout 110 encounters the backstop 224, a central portion of that box cutout 110 generally stops directly below the plunger 220, as illustrated in
In preferred implementations, the backstop 224 and/or one or more of the drive wheels 212 are adjustable to allow for adjustment for various sized and shaped box cutouts.
The machine 210 includes a second laser detector 224, which is utilized to trigger the beginning of a plunging routine. In some preferred implementations, the machine 210 includes one or more “flippers” or rotational fingers 227, which are configured to effect the flipping up or folding of a portion of a box cutout 202 once it is in position. Preferably, the activation of such rotational fingers 227 represents a step of a plunging routine triggered by the second laser detector 224.
In some preferred implementations, one or more clamps 226 are utilized to clamp down on a box cutout 202 to ensure proper positioning or folding of portions of a box cutout 202, e.g. during manipulation by rotational fingers 227.
Following any such folding, the plunger 220 is utilized to effect collapsing of a box cutout 110 via collapsing of the bottom panel 120 of the box cutout 110 downward. The plunger 220 effects such collapsing by thrusting downward against a middle portion of the score line 113 bisecting the bottom panel 120 of the box cutout 110.
The plunger 220 is preferably driven by a plunging mechanism for effecting movement of the plunging instrument. The plunging mechanism may comprise, for example, an elongate rod or bar that is mechanically, electrically, and/or pneumatically driven. In at least some implementations, some or all components of such a plunging mechanism may be integrated with, or considered part of, plunger 220.
The plunger 220 preferably comprises a plunging head. The plunging head is preferably sized and dimensioned based on the box cutout it is to apply pressure to. For example, for the box cutout 110, the plunging head preferably has a length generally corresponding to the length of the score line 113 that lies between left and right sets of the innermost lines formed in the bottom panel 120 of the box cutout 110, i.e., which preferably are the major score lines 119 in the box cutout 110.
The plunging head preferably tapers to a blunt end, e.g. a narrow curved or planar face, although in at least some implementations the plunging head may simply be thin and may not taper at all. Preferably, the plunging head does not taper to a sharp edge, although in at least some implementations it may taper to an edge.
In one or more preferred implementations, a plunger is configured such that plunging heads are removable and interchangeable.
As the box cutout 110 descends, it is guided by opposed freely rotating guide wheels 228, as illustrated in
Thereafter, the collapsed box cutout 110 is deposited into a collection area where a collector 242 pushes the collapsed box cutout 110 into a collection pen 240, as illustrated in
Preferably, the machine 210 includes a third laser detector 234 disposed proximate a portion of a plunging mechanism for driving the plunger 220. The third laser detector 234 is configured to detect each plunge of the plunger 220, and thus keep track of a number of box cutouts 202 processed by the machine 210. The collection area and/or the collector 242 preferably includes an indexing mechanism 240 which functions to elevate certain ones of the box cutouts 110 collected in the collection pen 240. For example, the indexing mechanism 240 might be configured to, based on detection of plunges by the laser detector 234, elevate one out of every five collected box cutouts 110, as illustrated in
Indexing of box cutouts 110 facilitates easy removal of a precise number of box cutouts 110 from the collection pen 240 in a precise manner. For example, a certain number of box cutouts 110 can be removed and themselves packed in an non-collapsed box cutout 110 itself disposed in an expanded box configuration for use.
Although described hereinabove with respect to box cutout 110, it will be appreciated that machine 210, or other similar machines, may equally be configured for different sized and shaped box cutouts.
In one or more preferred implementations, one or more of the drive wheels 212 are adjustable so as to allow the machine 210 to be configured for different sized box cutouts.
In a preferred implementation, a machine is configured for box cutouts intended to function as disposable coolers, such as those disclosed in the provisional patent application 61/452,640, incorporated herein by reference.
In at least some implementations, rotational fingers are not utilized to effect folding of a box cutout prior to plunging. For instance, in an alternative the use of fixed fingers or other fixed physical objects are positioned so as to be engaged by the box cutout during plunging, thereby resulting in manipulation of the box in certain predefined manners. In yet another alternative, both rotational fingers and fixed fingers are utilized.
In some preferred implementations, fixed fingers are positioned at a forty-five degree angle relative to a vertical plane. Additionally, or alternatively, fixed fingers may be disposed at a forty-five degree angle relative to a horizontal plane. In at least some implementations, although described as “fixed”, fixed fingers are adjustable through one or more planes but, during operations of the machine following any such setup of the machine, the fixed fingers remain stationary.
It is believed that the use of such fixed fingers or other fixed structures to enable folding during plunging results in increased product rates because any momentary pause, however, short, that is required for flippers to actuate is obviated.
In some implementations, a machine includes glue applicators configured to apply glue to both top and bottom (inner and outer) sides of a box cutout. For example, with respect to a cutout 3101, a machine is preferably configured to apply glue to the inner side of the panels 322 and/or the panels 313 to secure such panels together when plunged; to the outer side of the panels 312 and/or the panels 313 to secure such panels together when plunged; and to the outer side of the panels 322,323 to secure such panels together when plunged.
The Appendix, which is incorporated herein by reference, includes photographs of an exemplary machine in accordance with one or more preferred embodiments of the present invention. In use, the machine has been observed to make box cutouts in the collapsed configuration as represented in
Although described hereinabove in the context of a machine configured for transitioning of a single box cutout at a time, e.g. machines having a single plunger for plunging of a single box cutout at a time, in one or more preferred implementations a machine is configured with two or more plungers for simultaneous plunging of two or more box cutouts. In some implementations, collapsed box cutouts may then be collected in different collection areas, while in other implementations, all such box cutouts may be collected in a single collection area.
Although description herein largely focuses on box cutouts, systems, methods, and apparatus described herein could equally be utilized in other contexts, including other packaging contexts. For example, innovations described herein could equally be utilized in the context of cartons having non-corrugated walls.
