Abstract

A general shape folding shopping bag (10) with a bottom that can be folded inward is formed with a fold line that can be shaped to extend the bottom in a general plane. A side surface (11) that is a rectangular shape of the bag when recessed and is recessed outwardly and a side surface (11) that is recessed inward when folded are formed. The bottom or closed end is formed from a plurality of overlapping connecting portions (12) extending between the opposing end (13) of the side surface (11) and the overlapping connecting portion (12) so that the side surfaces (11) can be folded together. In addition, the bag (10) can be folded inward with respect to the fold lines (14, 16). The overlapping connection (12) has a tab (17) that is glued or adhered to the opposite bottom. The bag is made of a slightly stiff material such as cardboard or plastic and has a handle (22).

Description

  The present invention preferably relates to a packaging material formed from a somewhat rigid material, and more particularly to a container, a bag, a large container, and the like.

  Although the present invention will be described with respect to shopping bags, it will be understood that it has broad applicability to many other applications.

  A typical shopping bag is made of cardboard, plastic or plasticized material, etc., which is open at the top and is formed as a foldable columnar article. Often, these bags are provided with a handle near the open top to carry the bag during use.

  Throughout the following specification and claims, the word “comprise” and “comprises” or “comprising” unless the context before and after requires another meaning. The term “includes the stated integers or steps, or integers or steps, but is not understood to exclude other integers or steps, or integers or steps.

  Reference to any prior art in this specification does not recognize or suggest that the prior art forms part of common sense in Australia.

  The space in the rectangular bag is not fully utilized, except for containing items, substances or objects that conform to the rectangular shape and are configured to form a container shape. When a container is used to accommodate a product that does not have a shape that can completely use the space, the material from which the container is made, the rectangular columnar bag, or the unnecessary unused space in the container is wasted.

  A known shape of a foldable bag that is typically used to contain soft or supple items is a pillow pack. The pillowcase packet has two bent rectangular sides with at least one openable end for packing into the packet. If the individual ends are formed by a pair of flaps, the flaps extend from the bent hinge lines along the opposing ends of the individual sides. The flaps are folded with respect to their individual hinge lines and are held in overlapping shapes by over-centre action resulting from the curvature of the hinge lines. Pillowcase-like wraps can be easily opened by rotating the outermost closed flap around a bent hinge line that folds inwardly at the end of each side. Thereafter, the underlying flap can be similarly rotated to fully open the end of the pillowcase-like packet.

  When the flap is closed, there is no flat end surface on which the wrapping material can be placed on the closed end without covering the lid, and the pillowcase-like wrap is a closed, bent end.

  Prior art relevant to the present invention includes not only the disclosure of JP2003312683 but also U.S. Pat. Nos. 3,437,258, 5,048,749, 6,152,359, 5,911,358, and 6,513,704.

  The present invention is a wrap, bag or container with at least one closed end, which is assembled and at least one set of interconnected and substantially rectangular shapes when folded when folded. The outwardly convex side panel or wall and the closed end formed from one part or a plurality of parts connecting the adjacent ends of the individual side panels. Or a plurality of parts, wherein the side panels are folded or crushed toward the inside of the container on opposite sides of a plane having a set of opposing ends of the side panels when the side panels are collapsed together; The purpose is to provide a bag or container.

  Preferably. The one or more parts are a single part when the packet is formed, and a fold line that facilitates folding of the parts inside the side panels when the side panels are folded together. It is preferable to have. In a further preferred form, the fold line has perforations along at least a plurality of fold lines.

  In other embodiments, adjacent components are arranged and flattened substantially flat when assembling the wrap, bag or container to withstand outward displacement of the part from the wrap, bag or container. The parts forming the connection have an overlapping relationship.

  In another form, the fold line is folded substantially perpendicular to the plane when the container is assembled.

  In yet another form, when the container is assembled, the fold lines are folded at different and decreasing angles with respect to a plane from an intermediate point between the opposite side edges to one opposite side edge. It has been.

  Preferably, the closed end of the container is provided with its base and the opposite end of the closed end of the container is open for inserting an item into the container.

  In a further embodiment, the bottom plate is placed inside the side wall and is detachably pasted. The bottom plate preferably has a shape complementary to the shape of the bottom. When the packet is assembled in the open configuration, the bottom plate is removed from the side and the components are placed back on the closed end of the packet.

  In yet another embodiment, the overlapping portions are bonded together when the packet is assembled.

  In another embodiment, the open end of the container according to the present invention comprises a handle.

  In a particularly preferred form, the packet or container according to the invention is formed from a single-part workpiece, cut, folded, glued and crushed container that can be spread out in an assembled state. I will provide a.

  The present invention will now be described by way of example with reference to the accompanying drawings.

  The bag 10 shown in FIGS. 1A and 1B includes two outwardly projecting rectangular side surfaces 11 and a bottom formed from a plurality of overlapping connecting portions 12 extending between opposing ends 13 of the side surface 11. . The individual overlapping connections 12 fold into the bag or container 10 with respect to the fold line 14 when the side surfaces 11 are collapsed together.

  A bottom plate (not shown) removably applied to the inner surface of the side surface 11 is manually removed when the bag 10 is unrolled or assembled from a collapsed or flat state. The bottom plate having the same planar shape as the stretched bottom part is pushed against the inner surface of the overlapping connecting portion 12 to ensure rigidity and form the bottom, and the overlapping connecting portion 12 is moved into the bag 10. Prevents it from being folded.

  In FIG. 1A, a hole 15 is shown in the side 11 for attaching a handle (not shown) to the adjacent open end 16 of the bag 10.

  2-6, common elements or components have the same reference numbers as used in FIGS. 1A and 1B.

  In the semi-processed product (blank) in FIG. 2-4, the fold line is indicated by a wavy line, while the cutting line is indicated by a solid line.

  In FIG. 2, the overlapping overlap 12 at the bottom is formed from two halves, and the two halves 12 can be folded inward and moved outward to form a flat bottom in the bag 10. For this purpose, it has a fold line 16. The tab 17 is configured to adhere to the overlapping connecting portion 12 at the opposite bottom during assembly of the workpiece, such as by gluing. The hinge tab 18 is configured to be adhered to the inside of the end 19 when the side surface 11 is joined after the side surface 11 is folded with respect to the fold line 20 during assembly.

  In the embodiment of FIGS. 3 and 4, instead of the single folded overlap connection 12 in the embodiment of FIG. 2, it has a plurality of separate overlap connections 12.

  The workpiece of the embodiment shown in the drawings is typically formed by die cut, folded and bonded in a manner similar to that employed in known shopping bag configurations.

  Finally, the inventive concepts within any of these aspects can be incorporated in a variety of structures, and it is understood that the general concepts described above are not replaced by the details of the accompanying drawings. Should do. Various alternatives, modifications, and / or additions may be incorporated into various structures and member arrangements without departing from the spirit or scope of the present invention.
