The use of containers to transport and store items is well known. For example, an individual may desire to use a container to carry many small items that can be easily scattered or to store and transport food items, such as a workplace lunch. A disadvantage of typical containers is that the container occupies the same volume regardless of whether it is empty or whether it has contents therein. A collapsible container that can easily be transformed between a flat configuration and a deployed configuration is therefore desired.
According to at least one exemplary embodiment, a collapsible container is disclosed. The collapsible container can include a top section, a bottom section hingedly coupled to the top section along a first side edge of the bottom section. There may be a flap section disposed over the top section and hingedly coupled to the bottom section along a second side edge of the bottom section. The collapsible container may also include a pair of first endwalls, each first endwall hingedly coupled to an end edge of the top section, and a pair of second endwalls, each second endwall hingedly coupled to an end edge of the bottom section. The top section is further divided by crease lines into narrower subsections. The bottom section is further divided by crease lines into at least three narrower subsections.
According to another exemplary embodiment, a blank for a collapsible container is disclosed. The blank can include a sheet of material divided by a pair of hinge lines into a top-forming section, a bottom-forming section and a flap-forming section. The top-. forming section may be hingedly coupled to the bottom-forming section and the bottom-forming section may be hingedly coupled to the flap-forming section. A pair of first endwall-forming sections may be hingedly coupled to the top-forming section, and a pair of second endwall-forming sections may be hingedly coupled to the bottom-forming section, and an opening may be defined in the top-forming section.
According to another exemplary embodiment, a method for forming a collapsible container is disclosed. The method can include providing a sheet of material divided by a pair of hinge lines into a bottom-forming section, a top-forming section hingedly coupled to the bottom-forming section and a flap-forming section hingedly coupled to the bottom-forming section, a pair of first endwall-forming sections hingedly coupled to the top-forming section, and a pair of second endwall-forming sections hingedly coupled to the bottom-forming section. The top and bottom sections may further be subdivided by crease lines into at least three narrower subsections, thereby creating a flat central portion and two diagonal portions. The method can further include folding the sheet so as to place the top-forming section facing and adjacent the bottom-forming section, folding the sheet so as to place the flap-forming section facing and adjacent the top-forming section, and aligning the endwall-forming sections.

Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.
As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiment are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.
Referring to the figures generally, a collapsible container may be shown.
Each of the top and bottom sections may further be hingedly coupled to endwall sections 108, disposed at both longitudinal ends of each of the top and bottom sections. The endwall sections 108 can be disposed between hinge lines 114 and the proximate transverse edges 115 of top and bottom sections 102, 104. Each hinge line 114 may include a segment 114a extending substantially transversely between a pair of crease lines 118. Each hinge line 114 can further include a pair of segments 114b extending substantially diagonally between the transverse segment and a terminal end proximate the edge of the corresponding top section 102 or bottom section 104. Each transverse edge 115 may further include a segment 115a extending substantially transversely between a pair of crease lines 118 and a pair of segments 115b extending diagonally between the crease lines 118 and the terminal end proximate edge of the top section 102 and bottom section 104. Each endwall 108, may be divided by crease lines 118 into 108a, 108b, and 108c.
Flap section 106 may have a shape substantially similar to the portion of top section 102 that is disposed between hinge lines 114. The flap section is divided into subsections 106a, 106b and 106c, by hingelines 130a and 130b. In some exemplary embodiments, flap section 106 may have a shape substantially similar to the portion of top section 102 that is disposed between hinge lines 114 plus a portion 104a of bottom section 104 that is adjacent top section 102c and disposed between hinge lines 114 and a crease line 118. In such embodiments, flap section 106 may be partitioned by a hinge line 112c. The extra portion 106d may be couplable to section 104a when the flap portion 106 is closed over top portion 102. In some exemplary embodiments the flap section consists of only section 106a, thereby creating a flap to couple to section 102a on top section 102 as shown in
In some exemplary embodiments, top section 102 may include an aperture 120 defined therein, as shown in
Focusing on
Subsequently, blank 100 may be folded along hinge line 112b such that flap section 106 is disposed adjacent and facing top section 102, and such that top section 102 is disposed between flap section 106 and bottom section 104. Top section 102a and flap section 106a may then be adhered or fastened to each other proximate hingeline 112b. This may be accomplished by the provision of an adhesive 110 substantially at adhesive areas 128 (shown in

In some exemplary embodiments, Top section 102 and bottom section 104 may then be adhered or fastened to each other at the endwalls 108 between the creaselines 116 and the terminal end of the blank. This may be accomplished by the provision of an adhesive 110 substantially at adhesive areas 128 (shown in
To place container 160 into a deployed configuration, the endwall sections 108 may be depressed inwardly and in the direction of bottom section 104, as shown by the dotted arrows in
Hinge lines 130a and 130b in the flap section, allow the flap 106, to fold into section 106a, 106b and 106c and follow the contour of the top section, forming a lid. Section 106b lies flat adjacent to top section 102b, as defined by the endwall 108b. In some exemplary embodiments the flap section may include an overlapping subsection 106d, defined by hinge line 112c. When in use, subsection 106d folds over hinge line 112a and overlaps a portion of section 104a on the bottom forming section, thereby further sealing the container. Rotating the flap open via hinge 130b enables partial opening of the container, in the rotated open position, the underside of section 106c is presented at an angle and provides a signage surface. Rotating the flap open via hinge 130a enables full opening of the container, in the rotated open position, the underside of section 106b is presented at an angle and provides a signage surface. In other exemplary embodiments there maybe a further crease line, longitudinally across the center of section 106b. This would allow the lid to fold thereby not obstructing the view of the user, when the container is in use. In further exemplary embodiments the flap portion consists of 106a alone. This is to provide coupling surface to the top forming portion 102 as shown in
a and 3e show rim 160 may be created between the aperture 120 and hinge line 112a and crease lines 114a on both longitudinal edges, thereby forming a rim around the aperture 120. The rim 160 secures end wall segments 115 in place and forms part of the said load bearing lock. Further rim 160 secures items within the cavity 200 and creates a gripping surface to hold the container. In some exemplary embodiments the rim 160 may include a thumb rest surface. In other exemplary embodiments rim 160 may include notches or scalloped sections, to secure the placement of tools or utensils within the container. The flap sections 106b and 106c interface with the rim 160, thereby sealing the aperture, 120, of the cavity.
The bottom forming section is deployed into two diagonal sections 104a and 104c and a flat portion 104b. The top forming section is deployed into two diagonal sections 102a and 102c and a flat section 102b. Flat sections 104b and 102b allow the container to be set flat on a surface or stacked, one atop the other.
In some exemplary embodiments, variations in the configuration of the container blank may be provided so as to include additional features in the collapsible container.
a shows another exemplary embodiment of a blank 500 for a collapsible container. Features similar to the embodiment of blank 100 are indicated by similar reference numerals, but with a hundreds digit of 5. In the exemplary embodiment of blank 500, tabs 532 may be provided at the edges of each endwall 508, and proximate hinge line 512a. Each tab 532 may be coupled to the corresponding endwall 508, and may be shaped so as to define a slit 534 between the tab 532 and the edge of the endwall 508. Additionally, latching tabs 536 may be provided proximate the longitudinal edge of flap section 506d and extending longitudinally past the proximate transverse edge of the flap section 506d. Consequently, when container 550 is formed from blank 500, as shown in
Turning to
In yet further exemplary embodiments, a latch 144 may be pivotably coupled to bottom section 102. When container 150 is in a deployed configuration, latch 144 may be received in a slot 145 defined in flap section 106. Latch 144 may then be pivoted in an orientation that precludes latch 144 from being withdrawn from slot 145, thereby maintaining flap section 106 in a closed configuration. In yet further exemplary embodiments, fasteners 146 may be provided on bottom section 104, and complementary fasteners 148 may be provided on flap section 106. When container 150 is in a deployed configuration, fasteners 146 may engage complementary fasteners 148 so as to maintain flap 106 in a closed configuration. The fastener and complementary fastener pairs may be any known fasteners, such as snaps, hook-and-loop fasteners, and so forth. In some exemplary embodiments, bendable extensions may be disposed from the container to secure the orientation of the container. For example, bendable wire 149 may be disposed from section 102 so that it may bend over section 106, locking the orientation of the container.
