The present invention is generally related to container forming machines. More particularly, embodiments of the present invention pertain to systems, apparatuses, and methods for forming and erecting Bliss-style containers from pre-cut material blanks.
2. Background and Description of Related Art
There is an ever increasing need for better containers to hold commodities having various sizes, shapes and dimensions such as fresh fruits and vegetables, canned and bottled goods, and a wide variety of other products. As new products are developed, new requirements for packing, shipping and storing various quantities of such products arise. Every time such requirements arise, or a new product is developed, there is a need for a new container design, as well as a machine to manufacture it.
In the packaging industry, numerous fiberboard containers and designs have been developed over the years. Such containers are typically constructed of a corrugated material. These materials may be single face corrugated, single wall (double-faced) corrugated, double wall corrugated, triple wall corrugated, etc. Containers may also be made of other paperboard products including, without limitation, container board, boxboard, linerboard, and cardboard.
Many different container box styles and types have also been developed over the years, each being optimally suited for one or more particular products or industries. Slotted box styles include such types as regular slotted containers (RSC), overlapped slotted containers (OSC), full-overlapped slotted containers (FOL), center special slotted containers (CSSC), bag-in-box containers, center special overlapped slotted containers (CSO or CSOSC), center special full-overlapped slotted containers (SFF), and snap-bottom boxes, among others. Telescoping boxes include such types as full-telescope design-style boxes (FTD), full-telescope half-slotted boxes (FTHS), partial-telescope design-style boxes (PTD), partial-telescope half-slotted boxes (PTHS), design-style boxes with cover (SDC), half-slotted boxes with cover (HSC), double-covered boxes (DC), interlocking-covered boxes (IC), bulk bins, and double-thickness score-line boxes, among others. Folder style boxes include such types as one-piece folders (1PF), two-piece folders (2PF), three-piece folders (3PF), four-piece folders (4PF), wrap-around blanks, self-locking trays, tuck folders, and one-piece telescopes (1PT) among others. Slide-type boxes include such types as double-side boxes (DS), and triple-side boxes (TS), among others. Rigid boxes include Bliss boxes and recessed-end boxes, among others. There are also self-erecting boxes, and numerous interior forms for boxes.
In the industry, the terms “case” and “box” are often used interchangeably. These terms each refer to a large, usually rectangular container made out of paperboard which is designed to hold a given number (e.g. 12 or 24) of smaller units such as cartons, bottles, cans, or produce pieces.
Bliss-type boxes have special characteristics which make them highly desirable for use in bulk packing industries such as meats, explosives, fresh fruits and vegetables, and other areas where strong construction and stacking strength are important. Bliss boxes were first developed in the 1920s, and were the subject of a number of early U.S. patents (e.g. U.S. Pat. Nos. 1,697,709 and 1,974,527). Generally speaking, a Bliss box is made of three distinct pieces of paperboard material. The first is an elongated piece of material, sometimes called a body matt (or main blank or main part), which is folded around itself in the shape of a rectangular tube forming the bottom, sides and top of the final box. In some Bliss-type boxes, separate end panels, usually mirror-images of each other, are attached to the open end of the larger piece to form the completed Bliss box. The corners of the side panels typically fold over the corners of the front and back panels of the body matt on the outside, giving the Bliss style of box good corner and stacking strength. The bottom of the Bliss box is generally solid which avoids the need for bottom sealing.
Because of its three-part construction, Bliss style boxes offer a wide range of variations in both construction and materials. For example, the end panels may or may not include upper flaps for closing the top of the box. The body matt may include two large flaps (one on either side) to form the top of the box so that these flaps either meet or overlap; or, there may be only one large top flap (with or without a tuck-in lip) provided to form the top of the Bliss box. Top flaps from the side panels may or may not be provided, or some other suitable combination of large or small flaps from the side panels and body matt may be employed.
Similarly, the corner-area overlaps provided by the side panels may vary widely depending upon the degree of strength required. In some Bliss box variations, flaps are provided along the sides of the body matt so that, when the body matt is folded over itself, these flaps create a frame on either end to which the side panels may be attached (on the inside of the body matt). This way, instead of side-panel flaps overlapping the outside of the body matt corners for attachment and strength, body matt flaps in these corners overlap the side panels. Such frames may be made with panels along both sides as well as the bottom end of the body matt. In many cases, the side panels and the body matt may be made of different paperboard materials (e.g., corrugated body matt and linerboard side panels). The overlapping areas of Bliss boxes are generally glued together, but may also be adhered using staples, rivets, or other similar attachment devices.
The process of manufacturing Bliss boxes first requires the creation of the three pieces of the box. The size and shape of the final box is determined by the dimensions of these pieces which are, in turn, determined by the ultimate product to be placed therein. Once these dimensions are determined, the appropriate method and amount of top flap overlap is determined, as well as the manner and amount of attachment of the side panels to the body matt.
Special Bliss box forming machines have been developed over the years to assemble these three paperboard pieces into the completed Bliss box. Different styles of such container-forming machines have been in existence for many years; however, such machines are generally limited to forming only the most basic of the many possible variations of Bliss boxes.
The need has now arisen for a container in which the main blank has flaps, extending from the side panels, for folding and completing the ends of a box. In contrast to conventional Bliss boxes where end panels are used to attach to and wrap around edges of the side panels, side support parts are provided inside the formed body matt such that the side panel flaps overlap the side support parts. The side support parts provide increased structural integrity as opposed to that offered by end panels, while at the same time eliminating the possibility that the end panels will detach from the side panels resulting to carton failure. Further structural stability can be provided by bottom flaps, extending from the bottom panel, for folding over the side flaps.
Unfortunately, conventional forming machines are incapable of forming such a special reinforced container, in part because of the order in which the various portions of the box are formed; mainly, the bottom flaps are folded over the side flaps which are folded over the support parts.
Therefore, there is a need for systems, apparatuses, and methods that can form a Bliss style container having side flaps extending from side panels, bottom flaps extending from a bottom panel, and side support parts.
Embodiments of the present invention provide apparatuses, systems and methods for forming a container. In general, one or more retractable folding members can be configured to fold side flaps of the main part of the container over the support part so as not to interfere with yet unfolded bottom flaps as the container is moving on a mandrel.
In some embodiments of the present invention, a system for forming a container can include a mandrel movable between a hopper for supplying a support blank of the container to be formed and a compression plate, a feeder located between the hopper and the compression plate for supplying a main blank of the container to be formed, the main blank comprising side panels and a bottom panel, and a folding assembly located between the feeder and the compression plate.

Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, and referring particularly to
In some examples, and without limitation, main blank 10 can have a bottom panel 110, a first side panel 120, a second side panel 130. In some examples, main blank 10 may also have a first top panel 140 and a second top panel 150. When formed, bottom panel 110, side panels 120 and 130, and top panels 140 and 150 correspond to the bottom, side, and top portions of the container, respectively. In some examples, and without limitation, the individual panels of main blank 10 may have a rectangular shape, however it is to be appreciated that other shapes are contemplated in accordance with some embodiments of the present invention. Further, while the individual panels of main blank 10 as illustrated in
In some embodiments, main blank 10 can further have flaps extending from one or more panels to form the ends of the container. In some examples, and without limitation, bottom panel 110 may have bottom flaps 113A and 113B on opposite ends. In some examples, and as illustrated by exemplary bottom flaps 113A and 113B, the flaps may comprise a single portion with a width about equal to a width of bottom panel 110. However, it is to be appreciated that the flaps of main blank 10 may comprise multiple portions and/or differing widths in accordance with some embodiments of the present invention.
For example, and without limitation, side panel 120 can have a flap formed of first portion 125A and second portion 123A on one end and first portion 125B and second portion 123B on an opposite end. Similarly, side panel 130 can have a flap formed of first portion 135A and second portion 133A on one end and first portion 135B and second portion 133B on an opposite end. As discussed more fully below, flaps having multiple portions may be used to form containers having non-right angled corners. And while the first and second flap portions of the example of
In some embodiments, the side support blank 20 can also include flaps extending from a main side support panel. For example, and without limitation, side support blank 20 can have a main panel 221, a first flap having a first portion 223A and a second portion 225A, and a second flap having a first portion 223B and a second portion 223B. As discussed more fully below, in some examples, and without limitation, a length of main panel 221 of side support blank 221 may be about equal to a width of the bottom panel 110 of main panel 10. It is to be appreciated that, while the exemplary side support blank 20 of
In some embodiments, one or more flaps of the main blank and/or side support blank may be bent by between 30 and 90 degrees. For example, and without limitation, flaps 125A and 125B may be bent 30 degrees with respect to side panel 120 and flaps 123A and 123B may be bent 60 degrees with respect to flaps 125A and 125B. In other examples, and without limitation, bottom flaps 113A and 113B may be bent 90 degrees with respect to bottom panel 110. In other examples, and without limitation, flaps 225A and 225B may be bent 45 degrees with respect to main side support panel 221 and flaps 223A and 223B may be bent 45 degrees with respect to flaps 223A and 223B. It is to be appreciated that other angles of bends are contemplated in accordance with some embodiments of the present invention.
As illustrated in the exemplary illustrations of
In some examples, and without limitation, the container may be formed by positioning one or more side support blanks 20, 30 perpendicularly against main blank 10. In some examples, and without limitation, the side support panels can be positioned such that an edge of main panel 221 of side support blank 20 is provided at the intersection of bottom panel 110 and bottom flap 113A. In some examples, and without limitation, the side support of the carton may be formed by bending the flaps of side support blank 20 (including, for example, and without limitation, portions 223A, 223B, 225A, and 225B) into a “C” shape. In some examples, one or more panels of main blank 10 (including, for example, and without limitation, side panels 120 and 130 and top panels 140 and 150) may be bent in a “C” shape around the formed side support. As such, it can be appreciated that the geometry and configuration of the side support blanks 20, 30 are to be selected such that, once formed, they may be tightly disposed between opposing side panels 120 and 130 of main blank 10.
In some examples, and without limitation, after side supports 20, 30 are formed and disposed within the partially bent main blank 10, side flap portions 123A and 125A of side panel 120 and side flap portions 133A and 135A of side panel 130 may be folded over main panel 221 of side support blank 20. Similarly, side flap portions 123B and 125B of side panel 120 and side flap portions 133B and 135B of side panel 130 may be folded over support blank 30.
In some embodiments of the present invention, and as discussed more fully below, and without limitation, the side flaps of the main blank 10 may be folded over, and held against, the formed side supports by folding members 311A, 311B, 311C, and 311D until bottom flaps 113A and 113B can be folded over the side flaps. Once folded, the bottom flaps and the side flaps of the main part can be compressed against the formed side support part to produce the formed container.
Referring now to the exemplary illustrations of
In some embodiments, mandrel 510 can be configured with cyclical or oscillating movement between a beginning and a end of a path. In some examples, and without limitation, mandrel 510 can be attached to one end of a movable lever by means of pivotally attached rod. The opposite end of the lever can be pivotally attached through a set of linkages to a pivot. The cam can cause the linkages to impart a back and forth motion to the lever as it rotates around the pivot. It can be appreciated that in such examples, the rod can pull the mandrel back and forth along a track. It is within the abilities of those in the art to implement other means for imparting oscillating motion to the mandrel in accordance with some embodiments of the present invention.
In some embodiments, devices can include one or more hoppers 530 for providing side support blanks 20, 30 of the container to be formed on sides 513, 514 of mandrel 510. In some examples, and without limitation, the hoppers may include generally L-shaped flanges of varying lengths in order to hold large or small quantities of side support blanks. In some examples, and without limitation, hoppers 530 can be configured with a position such that in operation, main panel 221 of side support part 20 can be aligned with side 514 of mandrel. In some embodiments, the flaps of side support blank 20 may be bent around one or more adjacent sides of the mandrel by one or more plows. For example, and without limitation, plow 540 may be provided between hoppers 530 and feeder 520 for bending a top flap of side support blank 30 around side 517. A second plow (not shown) may be provided for bending a bottom flap of side support blank 30. As such, it can be appreciated that by providing two plows, a support blank such as support blank 20 can be formed into a “C” shape wherein main portion 221 is adjacent to side 514 of mandrel 510, the top flap (which may include flaps 223A, 225A) is adjacent to side 517 of mandrel 510, and bottom flap (which may include flaps 223B, 225B) is adjacent to side 518 of mandrel 510.
In some embodiments, devices can include feeder 520, in a forward location from hoppers 530, for providing the main blank 10 of the container to be formed on the forward side 511 of mandrel 510. In some examples, and without limitation, feeder 520 can be configured with a position such that in operation, bottom panel 110 of main blank 10 is aligned with the forward side 511 of mandrel 510. In some embodiments, additional plows may be provided for bending side panels 120 and 130 of main blank 10 around adjacent sides of the mandrel. For example, and without limitation, plow 550C (shown in
It is to be appreciated that the interaction between, and operation of, mandrel 510, feeder 520, hoppers 530, plows 540, and 550A-D is sufficient to (i) form support blanks 20, 30 around the mandrel, (ii) align forward edges of the formed support parts against bottom panel 110 of main blank 10, and (iii) partially form side panels 120, 130 of main blank 10 around the formed support parts. It is within the abilities of those in the art to implement devices having other types and configurations of hoppers, feeders, and plows in accordance with some embodiments of the present invention.
In advantageous embodiments, devices may further include one or more folding assemblies, members, plows, and/or plates for bending and/or folding the side and/or bottom flaps of the main blank. As shown in the exemplary illustration of
Referring back to the exemplary illustrations of
In some embodiments, referring to the example of
In some examples, and without limitation, the fingers can be formed of nylon, plastic, or metal. In preferred embodiments, the fingers have a rounded distal portion (for example, and without limitation, a curved surface or a freely rotating wheel) for contacting the side flaps. In some embodiments, the fingers may be easily removable and replaceable in order to effectively fold and accommodate different sized containers to be formed.
In some other embodiments, referring to the example of
Referring back to
In some embodiments, the folding elements may be retracted from their extended positions after the side flaps are partially folded over the side support parts. In these examples, other means may be provided to finish folding the side panels over the side support part. For example, and without limitation, the folding elements may fold the side flaps about 45 degrees towards the side support parts and a plow or other bending structure may complete the fold. In some other embodiments, the folding elements may be retracted from their extended positions after the side flaps are fully folded over the side support parts (which in some examples, and without limitation, corresponds to about 90 degrees). In these examples, no other plow or bending structure may be necessary to complete the fold.
In some embodiments, the folding elements may be retracted immediately after folding the side flaps. In some other embodiments, the folding elements may remain in extended positions until the bottom flaps 113A, 113B are partially or fully folded over the side flaps. In some examples, and without limitation, the folding elements can remain in the extended position for holding the bent side flaps until the bottom flaps of the bottom panel can be fully or partially bent thereon. In some examples, and without limitation, the bottom flaps may be bent over the side portions by a plurality of plows (not shown).
In some embodiments, devices for forming a container may also include one or more compression plates for sealing the bottom flaps and the side flaps to the side support parts. In some examples, and without limitation, one or more surfaces of the side support part, the side flanges, and the bottom flanges may be sprayed with an adhesive. The squeezing action of the compression plates against the mandrel causes the adhesive to bond the ends of the container. As illustrated in the example of
Thus, the present invention provides apparatuses, systems, and methods for constructing a container having a main part with side and bottom flaps, wherein the side flaps may be folded over one or more side support parts positioned inside the container, without impeding movement of the container on said mandrel caused by yet unfolded bottom flaps. It is to be understood that variations, permutations, and modifications of the present invention may be made without departing from the scope thereof. As such, one or more features of some exemplary embodiments as described above may be practiced in conjunction with some other exemplary embodiments. It is also to be understood that the present invention is not to be limited by the specific embodiments disclosed herein or as illustrated in the referenced drawings, but rather, is defined in accordance with the appended claims when read in light of the foregoing specification.
