Description

[Technical field]

[0001] The present invention relates to a bag having an opening, a bottom and a fastener around the opening, the bag having two compartments with different openings. [Background technology]

[0002] 2. Description of the Related Art Bags made of a film such as a resin film have an opening within which a product is enclosed and the opening is then sealed to enclose the product. These bags are used in a wide variety of business situations. In this case, the bag generally has an opening, a storage portion and a bottom. In this case, the most common method is to open the bag to store the items inside, and then close it again after storage.In this case, the most commonly used closing device is a bag with a fastening device that is easy to open and close.

[0003] This fastener has a convex portion along the opening on one side of the inner surface of the bag, and a concave portion along the opening on the other inner surface facing the first, and the fastener seals the bag by interlocking the convex portion with the concave portion. Bags having this type of fastener that can be opened and closed freely are widely used. For example, there are a bag body shown in JP-A-9-309546 (Patent Document 1) and a bag shown in JP-A-10-250746 (Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-309546 [Patent Document 2] Japanese Patent Publication No. 10-250746 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, the closing and sealing of the contents in the bag is often performed by a fastener, in which case only one stored item or one storage section is closed and sealed. In this case, if multiple types of items can be stored individually in one bag, products with different numbers of packages can be stored separately and further removed, which is extremely useful. In particular, when selling goods, if the bag can be displayed and sold with different types of purchased goods stored in it, a variety of desired goods can be purchased collectively in one bag, and the bag can be used all at once, making it extremely convenient to use.

[0006] In particular, when housewives go shopping, they can purchase prepared foods, seasonings, etc., wrapped in individual wrapping portions, and use extremely convenient bags. In this case, it is possible to use a plurality of bags as a single unit by, for example, connecting the bags together, drilling holes through which the bags communicate with each other, and tying the bags together with a string or the like. However, this requires the use of separate bags for each item, and the bags are simply joined together, which requires separate bags for storage, and further requires the extremely time-consuming task of joining the bags together.

[0007] Furthermore, from the consumer's point of view, it simply looks like a large number of bags are strung together in a haphazard manner, which not only creates a sense of clutter, but also leads to the generation of a large amount of unnecessary waste. Therefore, there is a demand for a bag that can store a variety of products in a visually appealing manner and can be used for display and sale.

[0008] For this reason, it would be desirable to provide a bag having two openings and two compartments, the bag having an opening and a bottom and a fastener around the opening. [Means for solving the problem]

[Brief description of the drawings]

[0014] [Figure 1] 1 is a diagram showing an example of a bag body according to the present invention. [Diagram 2] FIG. 2 is a diagram showing an example of a state in which an item is stored in the bag according to the present invention shown in FIG. [Diagram 3] 4 is a diagram showing another example of the state in which an item is stored in the bag according to the present invention shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] FIG. 1 is a diagram showing an example of a bag according to the present invention, which is made up of a bag body having front and back surfaces (1a, 1b). Therefore, both sides of the bag body consisting of the front and back surfaces (1a, 1b) form side seal portions (2) at the sides to form the bag body. Furthermore, the bag has an opening (4) at the top, and the bottom (3) has a folded bottom portion to allow it to stand on its own. Furthermore, the opening (4) has a bite portion (6) that can freely open and close the opening (4).

[0016] The bite portion (6) is formed parallel to the opening (4) and is constructed at least in the vicinity of the opening. The bag has a central seal portion formed by sealing the front and back surfaces (1a, 1b) from the opening (4) to the bottom at the center. The central seal portion is formed by sealing from the opening (4) past the bite portion to the bottom of the bag body.

[0017] Therefore, one bag is divided into two bags by a central seal, and both sides of each are formed by sealing, and the bottoms are also formed as part of each bag. As a result, a central seal portion (9) is formed at least in the center of the bag body, which is formed by sealing the front and back surfaces (1a, 1b) from the opening (4) to the bottom, and further, the central seal portion (9) seals the front and back surfaces (1a, 1b) and also seals the mating portion at the position where it contacts the central seal portion (9). Furthermore, in this figure, a folded portion is formed at the bottom to enable it to stand on its own, and to facilitate folding, inclined seal portions (5) are formed at both sides of the central seal portion (9) extending to the bottom of each side.

[0018] In this case, a similar inclined seal portion (5) is formed along the other side of the bottom of the bag body, forming the bottom of the bag as a self-supporting bag. That is, an inclined seal portion (5) is formed between the side seal portion and the bottom portion. By forming an inclined seal portion (5) at the folded bottom of the bag body in this manner, a beautiful free-standing bag can be provided. The engaging portion (6) is shown as an example in which the concave engaging portion (6b) and the convex engaging portion (6a) are linearly engaged with each other to freely control the opening and closing of the bag.

[0019] In such a case, the central seal portion (9) seals the entire area of ​​the sealing portion, and the two are fused or welded together, so to speak, and are connected.

[0020] Therefore, the central seal portion (9) constitutes the side edges where the left and right bags are joined together. Incidentally, the bite portion (6) shown in this figure is merely an example, and any known member that allows the bag to be opened and closed may be used.

[0021] In this case, the mating portion (6) forms a central seal portion (9) by sealing, and is made of at least a sealable material. For example, thermoplastic resin. In addition, the engaging portions (6) on both sides of the bag body are also sealed in this figure to form double-sided seal portions on both sides of the bag body. Next, near the opening (4), there are handles (8) on both storage portions of the bag body.

[0022] In addition, in this figure, an example is shown in which the central seal portion (9) is formed in the center of the bag from the bag opening portion (4) toward the bottom portion (3). The present invention is not limited to this example, and may be formed at a position slightly shifted in the left-right direction, which is the forming direction of the opening (4) of the bag body. That is, the left and right bags may be formed to have different sizes. For example, the bag may be formed so that the storage capacity of the bag is large in one direction and the storage capacity of the bag is small in the other direction, so that the bag has different widths.

[0023] As described above, the bag of the present invention has both sides (1a, 1b) of the bag formed with side seal portions (2), has an opening (4) and a bottom (3), and further has a bite portion (6) parallel to the opening (4) near the opening. The bag has a central seal portion (9) in the center, which is formed by sealing the front and back surfaces (1a, 1b) from the opening (4) to the bottom (3). The front and back surfaces (1a, 1b) of the bag are sealed, and the bite portion (6) is sealed at the position where it contacts the central seal portion (9). Thus, the bag has two storage compartments.

[0024] Furthermore, this central seal portion (9) is not limited to this configuration, and the central seal portion (9) may be formed at a position offset from the center of the bag body in the left-right direction, which is the direction in which the interlocking portion (6) is formed parallel to the opening (4). That is, the central seal portion (9) may be formed by shifting it in the width direction of the bag body. Therefore, the left and right storage sections formed by the central seal portion (9) may have different sizes. Incidentally, the bag body according to the present invention is formed to be self-supporting by folding, but in this case, an inclined seal portion (5) connected to the bottom may be formed to enhance the self-supporting ability.

[0025] FIG. 2 is a diagram showing an example of a state in which a bag having two storage compartments according to the present invention is used. In this diagram, mushrooms and seasonings are stored in the storage compartment on the right, and half-cut cabbage is stored in the storage compartment on the left. Therefore, for example, when preparing a dinner menu, the necessary prepared foods can be stored in a bag having these two storage compartments and displayed for sale, allowing the necessary ingredients to be purchased all at once. In particular, it is possible to purchase the necessary ingredients and seasonings for cooking at home using a single bag, and it is possible to provide a convenient bag.

[0026] For example, the storage capacity of the storage section can be changed by shifting the central seal portion (9) in the width direction, and a bag with the desired storage capacity can be formed by appropriately adjusting the capacity depending on the purpose of the bag and the contents to be stored. Furthermore, the bag according to the present invention can maintain the openings (4) of each storage section openable and closable, making it possible to provide a bag that is extremely easy to use.

[0027] FIG. 3 is a diagram showing another example of a state in which the bag body having two storage compartments according to the present invention is used. In this diagram, grapes are stored in the compartment on the right and apples are stored in the compartment on the left. In this way, a plurality of kinds of fruits can be stored and displayed for sale, and only the necessary items can be stored and displayed for sale as required, and a bag body for this purpose can be provided. As described above, it is possible to provide a bag body that is extremely easy to use. [Explanation of symbols]
