JP2507719Y2 - Handbag for board - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handbag for a board.

In general, sushi, bento, Japanese confectionery, Western confectionery, decoration cake, and other plate-like folds or boxes need to be carried while being held horizontally.

The present invention relates to a carrying bag for holding a board-shaped product horizontally and carrying it, and more particularly to a carrying bag for a thick board-shaped product such as a decoration cake.

[Prior Art] An ordinary handbag has a vertically long bag body portion for storing items, and is not suitable for carrying a box of fragile contents as described above.

In such a case, it is common to use a furoshiki or hook a box or the like and hang it with a string from the center to carry it around. However, it is not appropriate to use these methods for selling goods because of the troublesome operation of stringing or the cost of furoshiki. Moreover, since the box is suspended only at the center of the upper surface of the box, the box is inclined when the weight of the contents is uneven.

The present inventors do not have the drawback of tilting when carrying, and
We have already proposed a handbag for a board that has a simple manufacturing process (Japanese Utility Model Publication No. 59-60916).

However, the bag proposed here has a drawback in that in the case of a thick plate-like object, it is difficult to put the product in the bag even if the corner bottom of the gusset is folded. Therefore, a bag of a size larger than that of the bag must be used, and when the bag is lowered, not only the appearance is bad, but also the original function of holding the bag horizontally may be lost.

[Problems to be Solved by the Invention] An object of the present invention is to provide a carrying bag suitable for horizontally carrying a thick plate-like object such as a decoration cake.

[Means for Solving the Problems] The present inventor has usually tried to extend the opening provided on the upper surface or the upper portion to the bottom film, which is convenient because the opening greatly opens when the item is stored. Even when a cut line is provided in the cut end, a fastening hole is provided at the tip of the cut line to find that the cut line is strong and strong, and the present invention has been made.

That is, the present invention is a plastic film carrying bag comprising a board-shaped bag body formed of a rectangular top film and a bottom film, and a carrying part capable of holding the bag body horizontally. An opening that opens to the left and right is provided along the center line of the upper surface of the section, and two handbags are formed along one of the left and right edges of the opening from one periphery of the bag portion to the other periphery that faces the bag portion. A tape-shaped film is hung, and both ends of each tape-shaped film are fixed to the peripheral part of the bag body, and one side edge of the two left-right tape-shaped films and the edge of the opening are separately fixed on the left and right sides. In what I did,
The present invention provides a handbag bag for a plate-like object in which cut lines extending from the opening of the top film are formed at both ends on the center line of the bottom film, and stop holes are provided at the ends of the cuts.

As the film used for the bag for carrying a board-like product of the present invention, a thermoplastic film or the like can be preferably used because a fusion step can be applied in manufacturing.

The present invention will be described in more detail by way of examples. 1 and 2 show the most typical embodiment of the present invention. The handbag bag for a board of this embodiment is made of a thermoplastic resin film, and includes a bottom film 1, a top film 2 and a handbag film 3. These films are made by simply folding one film as a raw material.

That is, as shown in FIG. 2, the bottom film 1 is bent at the left and right side peripheral portions 4 of the bag body so as to be continuous with the top film 2, and the top film 2 is further provided at the left and right opening edges 5. Folded handbag film 3
Are continuously and integrally fixed.

In the bag for bag of the present embodiment, the thus folded film is fused with the bottom film 1, the top film 2 and the bag film 3 at the upper and lower vertical peripheral portions 6 in FIG. Near the center of the edge 5,
Each has a finger hole 7.

A handbag reinforcing portion 10 is provided between the portion of the vertical peripheral portion 6 where the handbag film 3 is fixed and the central portion of the handbag film 3. The four handbag reinforcing portions 10 are formed by heat-sealing the handbag film 3 and the upper surface film 2.

The handbag reinforcing portion 10 is formed on a curved arc-shaped curve that is convex with respect to the side peripheral portion 4.

The curved handbag reinforcing portion 10 has a handbag film curved and fusion-bonded to the bag opening, so that the force applied to the end of the fusion-bonding fixing line is evenly distributed over the entire fusion-bonding curve. The strength of the handbag reinforcement portion 10 is improved.

Further, a cut line 11 and a stop hole 12 at the tip thereof are provided, which is a feature of the present invention.

This cut line is 5 to 20% of the vertical length of the bottom film, preferably 10 from the vertical peripheral portion on the center line of the bottom film 1.
It has a length of .about.15% and a stop hole 12 having a diameter of 5 to 20 mm is provided at the tip thereof.

These cuts 11 and the fastening holes 12 are made by first manufacturing the bag as described above, and then stacking dozens of these bags, and first, the fastening holes 12
It can be easily constructed by punching with a punch and then making cuts 11 by cutting.

In this case, even if the punched holes hang on the upper surface film or the handhold film, there is no influence on the strength.

Without this stop hole 12, the bottom film is torn from the tip of the cut 11 and the bottom is broken due to the weight of the stored items.

Also, if there is a handbag reinforcement part, the upper surface film is fixed to the handbag part, so that the opening edge does not spread,
This indirectly prevents the tip of the cut 11 of the bottom film from tearing. Further, even if the punching hole for the stop hole 12 is formed in the handbag portion, if the reinforcement portion is provided, the weight of the article is supported by the reinforcement portion, so that the strength of the handheld film is not affected.

In the present invention, it is preferable to make such a handbag reinforcing portion into a curved line because the strength of the handbag portion is improved.

The curved curvature and inclination of the handbag reinforcing portion 10 can be selected in an optimum manner depending on the shape of the bag and the type of stored items.

Therefore, even if a considerably heavy item is put in the bag-like bag of the present invention, it will not be damaged.

As shown in FIG. 1, it is preferable that the handbag reinforcement portion of the present invention is symmetrically provided at four positions in terms of balance.

When using the bag-like handbag of the present invention, the opening edge 5 is pushed to the left and right to store the board-like item in the bag body. At this time, since the cut 11 is provided, the product can be easily stored. The fingers are put into the left and right finger holes 7 from between the upper surface film 2 and the handbag film 3 and suspended. Since the handbag bag 3 for the board-like object of the present invention has the handbag film 3 and the upper surface film 2 continuously fixed, and the handbag reinforcing portion 10 is provided, the hanging force is applied to the left and right sides of the bag body. Even if the weight of the contents is uneven, the items are held horizontally because they are dispersed in the peripheral portion. In addition, the hand-curved reinforcing portion 10 having an arc curve with a convex center also has an effect of preventing breakage of the cut 11.

The hand-carrying film 3 of the hand-carrying bag for board-like objects of the present invention can be reinforced according to the weight of the product, such as widening the width or stacking two or three layers.

Finger holes 7 for hanging the carrying bag for the board of the present invention
Can be provided at the central portion of the upper surface of the bag portion and at or near the fold line of the opening edge 5. Especially, the opening edge 5
It is convenient to provide the fold line because the fold line can be punched from the top during manufacturing. Even if the bottom film 1 is punched at the same time during this punching, there is often no problem in use. The finger hole 7 can be formed by simply cutting open the fold line of the opening edge 5, but in this case, the force is concentrated at the end of the cut line, so that the finger hole 7 is easily torn. As described above, it is preferable from the standpoint of strength that the left and right finger holes 7 are formed into an elliptical shape by punching out the left and right folds.

Although the finger hole 7 is convenient in the carrying bag of the present invention,
Not necessarily. If the handbag film 3 has a certain width, the bags can be reliably hung by inserting fingers from both sides of the left and right handbag films 3.

The bag part of the present invention has a size according to the items to be stored,
The shape and thickness can be changed. Even if the peripheral shape is octagonal or circular, it can be easily manufactured only by changing the shape of the thermal blade that melts and cuts around the bag body used in the manufacturing process.

Further, when storing a thick product such as a decoration cake box, the bag body portion of the bag-like handbag of the present invention can be made by applying a known method for making a square bottom bag. That is, a gusset fold 8 having a cross section as shown in FIG. 3 is provided on the side peripheral portion 4, and as shown in FIG. It can be easily made by cutting with a fusion cutting process. FIG. 5 shows a perspective view of the bag-like handbag of the present invention manufactured in this manner. When putting an item in this, the opening is opened so as to tear to the bottom of the item below the vertical peripheral line 6 in FIG. 5, so even thick items can be easily stored in a bag that matches the size. be able to.

Next, it will be shown that the bag-like bag for carrying the present invention can be continuously manufactured extremely easily. In a typical manufacturing process of the bag for bag of the present invention, a tubular film sheet is gusseted in cross section as shown in FIG. 6 by a known method. Then, the central portion of the upper surface of the gusset fold is cut open to form a gusset fold as shown in FIG. Bottom film 1
Insert a metal plate between the top and the upper surface film 2 and press the arc-curved heat blade heated from above at a predetermined position to integrally fuse the handbag film 3 and the upper surface film 2 together. Then, the handbag reinforcement section 10 is made. Before or after this step, or simultaneously with this step, the finger holes 7 are punched out at a constant interval from above with a blade die to obtain a long film strip having the shape shown in the plan view of FIG. Finally, the portion indicated by the dotted line in FIG. 8 corresponding to the vertical peripheral portion 6 is fused with a hot blade to manufacture a handbag for a plate.

Then, a large number of bags cut in this way are stacked, punched out in the stop holes 12, and then the cuts 11 and positions are cut to manufacture the bag-like handbag of the present invention.

In this case, the punching of the finger hole 7 can be performed after the fusing of the vertical peripheral portion 6 and the punching of the stop hole 12. The bottom film 1 is also punched at the same time, but there is almost no problem in use.

[Advantage of Invention] The bag-like bag for carrying the present invention is easy to manufacture and can be put into a bag having a size corresponding to the size of the product, so that the product does not tilt when used and the product is stable. It has the advantages that it can be carried around, and that it can easily store even a thick plate-like object, and that its strength does not decrease.
