Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a bag suitable for packaging granular foods such as hailstones and bean sweets.

0002

[Conventional technology]

Hail, when granular food A such as bean sweets is stored in bag B, as shown in Figure 6, it will fall downward. If placed in a store, the display effect will be poor, and as shown in Figure 7, the plastic Store granular food A in tray C, wrap it in transparent bag B, seal it, and sell it. It was common for there to be.

0003 By packaging granular food A in bag B using tray C in this way, bag B Even when it was propped up, granular food A did not shift to one side and had an excellent display effect. However, using Tray C in this way increases the number of parts that need to be discarded after use, leading to pollution. Since this could be a contributing factor, improvement was desired. In addition, as shown in FIG. 8, by using a partition film D in the middle, It can achieve the same effect as the bag shown, but the number of materials used increases and the same improvement is not possible. It was wanted.

0004

[Problem that the idea aims to solve]

By using trays and partition films as shown in Figures 7 and 8, The display effect was excellent when used, and it was common, but the number of materials used increased and the Since the amount of waste increases, this invention eliminates the use of trays and We solved the desire for a bag that can be automatically filled and has an excellent display effect without using cut film. The purpose is to decide.

[0005]

[Means to solve the problem]

This invention has seals on three sides, excluding the upper opening, and a lower opening in the center. 1/3 to 1/2 of the length in the vertical direction from the seal part on both sides. The center seal part is formed by integrating the front and back sides of the bag with a gap of 2 to 4 times the width of the bag. This is a packaging bag for granular food characterized by the following.

[0006] In addition, the shape of the central seal part is dot-like, 1/3 to 1/3 of the length in the vertical direction from the bottom. It may have any shape with the upper end at position 2 and extending to the lower seal portion. Furthermore, the shape of the seals on both sides is such that the width of the storage area at the bottom is 1/2 to 2 of the width of the bag. This is a packaging bag for granular food that has a weight ratio of 0.3 to 3.

[0007]

[Effect]

Place the center seal part at a position of 1/3 to 1/2 of the vertical length from the bottom, and place the seals on both sides. Since it is formed at a position 2 to 4 times the size of the granular food from the mold part, the granular Food can be automatically filled from the opening of the bag. Even when the bag is propped up when it is filled, the granular food does not shift downward. It can be displayed as is.

[0008] In addition, the shape of the seals on both sides is such that the width of the storage area at the bottom is 1/2 to 2/2 of the width of the bag. By setting the range of 3, it can be used not only for automatic filling of granular foods but also for vertical filling. After filling, the granular food does not shift downward and can be displayed as is.

[0009]

【Example】

The material used in this invention has an outer layer of stretched polyester film and stretched nylon film. films with excellent mechanical strength and gloss, such as polypropylene films and stretched polypropylene films. , the inner layer is made of unstretched polypropylene, polyethylene, etc. and has heat sealability. It consists of a thick laminated film.

0010 FIG. 1 is an explanatory diagram showing one embodiment of the present invention. A bag with side seal parts 2 and 3 and a bottom seal part 4 at the bottom, with a bottom seal part in the center. 4, a dotted central seal is placed between 1/3 and 1/2 of the length of the bag in the vertical direction. This is a packaging bag for granular food provided with a section 5. This center seal part 5 is made by integrally sealing the front and back films of the bag. The distance from the side seal parts 2 and 3 is 2 to 4 times the size of the granular food, respectively. Provided as follows.

[0011] If the center seal part 5 is dotted as shown in Fig. 1, from the bottom seal part 4 Granular foods can be separated by providing spacing that is at least twice the size of the granular foods. When filled, it can be reliably stored all the way to the bottom as shown in Figure 2. At this time, it is possible to display the granular food product by standing it up without being pushed to the bottom.

0012 In addition to the dotted shape shown in FIG. 1, the central seal portion 5 has an upper end shaped like The position may be the same as in the figure, and it may be in a straight line that reaches the bottom seal part 4. 4, it may be in a discontinuous state instead of in a straight line as shown in FIG.

[0013] The center seal part 5 is not provided as shown in FIGS. 1, 3, and 4, and the side seal part 5 is not provided as shown in FIG. The shape of the side seals 2, 3 allows the same objective to be achieved. In this case, as the side seal parts 2 and 3 get closer to the bottom seal part 4, the cutting width increases. The width of the storage area at the bottom is 1/2 to 2/3 of the width of the bag. Ru. At this time, the starting point where the width of the seals of the side seal parts 2 and 3 widens is from the bottom to the vertical direction of the bag. A range of 1/3 to 1/2 of the length in the direction is suitable for automatic filling of granular foods. preferable.

[0014]

[Effect of the idea]

As described above, the present invention allows the bag to be placed at a specific position from the bottom or at the upper end of the bag. Since a central seal is provided, automatic filling of granular foods such as hail and bean sweets is possible. This allows for proper filling to the bottom. In addition, by providing a central seal, it is possible to stand up a bag filled with granular food. Also, the granular food did not shift downward and the display effect was excellent.

[0015] On the other hand, as shown in claim 5, the shape of the side seal portion is changed as it approaches the bottom seal portion. Therefore, make it wide, and the width of the bottom seal part should be in the range of 1/2 to 2/3 of the width of the bag. This makes it possible to automatically fill granular foods and ensure that they are filled all the way to the bottom. Wear. In addition, by making the seal width wider as it goes downwards, the bag can be placed upright. This prevented the bag from bulging at the bottom, resulting in an excellent display effect.

[0016] In this way, the sealing part of the bag can be improved without using separate parts such as trays or partition films. By doing so, it is possible to create a bag that can be displayed standing upright, which saves resources on materials. This makes it possible to reduce waste after use.
