Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handbag for a board, which is advantageous for continuous bagmaking.

In general, the present invention relates to a handbag bag used when carrying sushi, bento, Japanese confectionery, Western confectionery, decoration cake, and the like in a plate-like fold or carrying a box while holding it horizontally.

[Prior Art] A bag having a shape similar to that of the present invention has already been proposed as a bag for carrying a board-like object (Japanese Utility Model Publication No. 59-60916).

In the case of manufacturing the bag-like handbag proposed here, the tubular film sheet is gusset-folded in cross section by a known continuous folding method as shown in FIG. Then, the central portion of the upper surface of the gusset fold is cut open to form a gusset fold having a cross section as shown in FIG. Between the upper film 1 and the lower film 2 of this section, the metal plate 11
And insert the handbag film 3 against this plate.
A rectangular punching blade is struck from above to cut the finger hole portion from the handbag film 3 to form a finger hole.

Then, at the periphery 6, the whole is fused to fix the handbag portion and the bag body portion to manufacture a handbag bag for a plate-like object.

However, the biggest problem in the manufacturing process of this bag is the process of manufacturing the finger hole portion. That is, in the bag making process, it is difficult to hit the punching blade on the unstable metal plate inserted into the continuously moving tubular film, and in order to reliably drop the finger hole part. It takes a very strong force. As a result, the punching blades soon become less sharp and often have the drawback of having to stop the continuous operation and replace the blades. Also, in order to make sure punching, a receiving plate is placed under the lower film and punching to the bottom film at the same time, but the metal plate can be stably fixed, but there is a hole in the bottom of the product and it looks bad. Also, there is a drawback that the punching blade must be replaced.

[Problems to be Solved by the Invention] An object of the present invention is to provide a handbag for a plate-like object in which the manufacturing process of finger holes is simple.

[Means for Solving the Problems] In order to solve the above problems, the present inventor has conducted earnest research and, as a result, carried out an anti-fusing agent, such as ink, by hand with the finger hole portion, that is, the bag upper surface film 1. The invention was devised to be applied to the partial film 3 and punched out a finger hole with a high temperature blade heated from above, and the present invention was accomplished.

The present invention relates to a film handbag comprising a disc-shaped bag body and a handbag capable of holding the bag body horizontally, and an opening 5, which opens to the left and right along the center line of the upper surface of the bag body. 5, and a handbag portion composed of two tape-shaped films 3 and 3 formed by bending a film extending from both edges of the opening portion is provided with a handbag portion from one periphery 6 of the bag body portion to the other periphery 6 of the bag body portion. The tape-shaped films 3 and 3 are fixed to the peripheral portions 6 and 6 of the bag body, and the tape-shaped films 3 and 3 are attached to the inner edges of the center of the hand-carrying portion. Provided is a bag for carrying a plate-like object, characterized in that finger hole shapes 7 and 7 punched by a hot blade are formed at positions where the anti-fusing agent is applied in advance between the base tape film and the bag body film. To do.

Unlike the punching process, the fusing process adopted in the present invention is characterized in that it does not require force because it is cut by melting, and the cutting operation can be reliably performed even on an unstable plate in a tube. In this case, it is desirable to use a silicon plate instead of the metal plate.

In this case, the finger hole portion is once fused, but this fusion is easily removed by inserting the finger due to the effect of the anti-fusion agent.

A method of avoiding film fusion in the fusion cutting step by using such an anti-fusion agent has already been adopted in film processing. However, this conventional method uses a fusion inhibitor to selectively fuse only the portion to be fused when there are locations to be fused and locations to avoid fusion at the same time in the fusion cutting process. It had been. As in the case of the present invention, it is sufficient to simply punch through like a finger hole, and when there is no place to be fused, a fusion cutting process is purposely applied to prevent the fusion with an anti-fusing agent to facilitate punching. I have never had an idea to do so.

Therefore, the film used in the bag-like bag for carrying the present invention is limited to the plastic film which can be heat-fused.

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 for a board according to this embodiment comprises 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,
The bottom film 1 is bent at the left and right side peripheral portions 4 of the bag body and is continuous with the top film 2, and the top film 2 is bent at the left and right opening edges 5 and is continuous with the handbag film 3. ing.

The bag-like handbag for this embodiment is obtained by applying the anti-fusing agent at a position corresponding to at least the cutout portion of the finger hole between the upper film 2 and the handbag film 3 of the film thus folded. There is.

Since the finger hole fusing step is performed from above, the finger hole portion is lightly fused, but the finger can be easily inserted and the detachable bag can be lowered by hand when used.

The bottom film 1, the top film 2, and the handbag film 3 are fused at the upper and lower vertical peripheral portions 6 in FIG.

Further, in this embodiment, the handbag film and the upper film of the bag body are fixed to the outside of the finger hole of the handbag film by the four fusing lines 12 so that the handbag for the board can be easily carried.

When using the bag for bag of the present invention, the opening edge 5
Is pushed to the left and right to store the board-like product in the bag body, and the fingers are put into the left and right finger holes 7 from between the upper surface film 2 and the handbag film 3 to hang it.

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 which are continuously fixed, the hanging force is distributed to the left and right peripheral portions of the bag body. Even if there is unevenness, the product is held horizontally.

The handbag film 3 of the present invention can be reinforced according to the weight of the product such that the width of the handbag film 3 is wide, or two or three layers are stacked.

Of these, the two handbags are particularly preferable because they are easy to manufacture because of strength and easy gusset folding as shown in FIG.

When the method of the present invention is applied to the two handbags that are stacked on top of each other, the two handbags are fused at the edges of the fusing, so that the finger holes on which gravity is suspended can be reinforced during suspension.

[Effects of the Invention] The handbag bag for a board-like product of the present invention facilitates continuous production by improving the finger hole process, which was the biggest bottleneck in the manufacturing process of this type of bag. There is also an advantage that it is convenient for storage because the finger holes do not come apart and are lightly fused until you use.

In addition, when the present invention is applied to a two-ply handbag part that is the easiest to make as a handbag for a board, the two films have the advantage of being fused and strengthening the finger holes.
