Description

  The present invention relates to a handbag for packaging for storing various commodities for take-out, and more particularly to a handbag made from a sheet-like material such as paper.

  When handing over the sold products at the storefront, it is possible to store the products directly instead of the wrapping paper, or to install the packaged products, with the side plate standing on the bottom plate and with a hand above the side plate Handbags with open tops that are made with a sheet-like material are widely used, especially those made of paper.

Japanese Patent Laid-Open No. 11-301699

  The above-mentioned handbags are useful as packaging materials used when handing over goods to the buyer at the store because packaging is completed simply by dropping the goods into the bag, and they can be easily carried using the hand. Some types were difficult to use.

  For example, when storing items that may damage the product if it is shocked, turned upside down, or tilted, such as a box packed with cake, the product cannot be dropped and stored in a bag. It was. In this case, it was necessary to hold the product and the box filled with it with both hands so that it stays level and gently house it in the bag, but since the bag is deep, insert both hands from the opening down to the bottom. It was difficult, and it took time for packaging when selling products at the store, which caused sales efficiency to deteriorate.

  Also, when a buyer takes out a product or a box filled with it from a handbag, it cannot be released by turning the bag sideways or upside down. In this case as well, it was necessary to hold the product and the box packed with it with both hands and gently pull it up from the inside of the bag. However, because the bag is deep, it is still necessary to insert both hands from the opening to the bottom. It was difficult and difficult to use.

  The present invention has been created for the purpose of providing a handbag for packaging that solves the above-mentioned problems, and comprises a sheet-like material in which a side plate is erected with respect to a bottom plate and a hand is provided above the side plate. In a bag body with an open top surface, by providing a plurality of crease lines acting as valley fold lines and mountain crease lines alternately in the vertical direction on the peripheral side of the side plate, the bag body has a bellows shape in the vertical direction. It is characterized by being extendable.

  Further, in the above invention, the rigidity of the bottom plate is increased with respect to the side plate, and a plurality of standing pieces that undulate in a flap shape are provided on the bottom plate, and the box to be accommodated with the interval between the standing pieces is provided between the standing pieces. A packaging handbag arranged so as to be located at the position is disclosed as the second invention.

  According to the packaging handbag of the present invention, a plurality of crease lines that act as valley fold lines and crease lines that act as mountain fold lines are provided alternately in the vertical direction on the peripheral side of the side plate constituting the bag body. When a pressing force in the downward direction is applied to the bag body from above, the sheets constituting the side plate are alternately folded inward (valley direction) and outward (peak direction) by folding lines, and a large number of bellows continuous in a bellows shape Will be expanded and contracted to an arbitrary height depending on the pressing condition (see FIGS. 5 to 8). Therefore, if the height of the bag body is reduced when storing or taking out the product, it is possible to easily hold the product from the side without inserting both hands from the opening to the bottom as in the prior art. The effect which becomes.

  As described above, according to the present invention, since it is not necessary to insert both hands from the opening to the bottom of the bottom when putting in and out of the contents, it has been abandoned as a packaging for cakes and the like from the viewpoint of ease of use. It is possible to realize a packaging bag that is long in the vertical direction and has a small planar dimension and a large vertical dimension. As a result, instead of storing a large number of cakes together in a box expanded in the plane direction when storing cakes, for example, preparing a plurality of elongated boxes that store a plurality of cakes in a row in the front-rear direction and in a width direction, It is also possible to sell in such a manner that these are stored in small portions, and these boxes are stacked up and down and stored in a bag. Further, it is possible to realize a packaging bag aiming at a unique design effect by making use of the vertically elongated shape having a small planar dimension and a large vertical dimension.

  According to the second invention, the rigidity of the bottom plate with respect to the side plate is enhanced, and a plurality of upright pieces that undulate in a flap shape are provided on the bottom plate, and the box that should accommodate the interval between the upright pieces is provided between the upright pieces. Since the standing piece of the bottom plate is raised (see FIG. 9) and the box containing the product is placed between them (see FIG. 10 to FIG. 12), the standing piece is placed. As a result, the movement of the box body is restricted, and the box body is prevented from dancing in the bag due to vibration or inclination during transportation. In addition, even if the above-mentioned standing piece is provided in the bag of the prior art, in the present situation where both hands are inserted from the opening to the bottom and the box is housed in the bag, the box is raised. It is extremely difficult to place them accurately in between, and the second invention can realize its functions and effects for the first time on the premise of the present invention.

  Hereinafter, specific examples of the packaging handbag of the present invention will be described with reference to the accompanying drawings. 1-5 is a figure which shows the expansion | extension state of a handbag. The handbag of the present invention has a structure in which the side plates 3, 3 and 4, 4 are erected with respect to the bottom plate 2 to form a bag body having an open upper surface, and the hand handles 7, 7 are provided above the side plates 3, 3, It is configured by pasting together the shaped materials. Further, here, a rectangular bag body is formed by standing front and rear side plates 3, 3 and left and right side plates 4, 4 with respect to the four sides of the rectangular bottom plate 2, but the number of side plates is Of course, it is not limited.

  By providing a plurality of crease lines acting as valley fold lines and crease lines acting as mountain fold lines alternately in the vertical direction on the peripheral sides of the side plates 3, 3 and 4, 4 of the bag body configured as described above, When a downward pressing force is applied to the bag body from above, a large number of wrinkles that are folded inwardly (in the valley direction) and outwardly (in the peak direction) and are continuous in a bellows shape are formed on the side plate. (See FIGS. 5 to 8). In this case, in this embodiment, the left and right side plates 4 and 4 have the folding line L4 acting as a valley fold line as the folding line continuous to the folding line L1 acting as the mountain fold line provided on the front and rear side plates 3 and 3, respectively. The left and right side plates 4, 4 are arranged as the crease lines L2 that act as mountain fold lines as the crease lines that are continuous with the crease lines L 2 that act as the valley crease lines provided on the front and rear side plates 3, 3. 3 and the side plates 4 and 4 on the left and right sides are folded at the corners (see FIG. 9).

  In addition, the thickness of the bottom plate 2 is increased with respect to the side plates 3, 3, 4, and 4 to increase its rigidity, and a plurality of upstanding pieces 5 that undulate in a flap shape are provided on the bottom plate. This upright piece 5 is formed by making a cut in a tongue shape leaving the non-cut portion 6 in the bottom plate, and when it is pushed up by a fingertip, it rises and falls in a flap shape using the non-cut portion 6 as a hinge ( (See FIG. 9). And the movement of a box is blocked | prevented by the standing upright piece by arrange | positioning so that the box B which should be accommodated in a carrying bag may be located between standing pieces by the space | interval of standing pieces 5 (FIGS. 10-10). 12).

  Here, paper is assumed as the sheet-like material constituting the bag, but it is limited to paper as long as it has flexibility to bend along the folding line and rigidity to stop when folded or folded. Of course, this is not possible.
