Description

  The present invention relates to a sealed bag that can form an opening in a step when the sealed bag enclosing food is opened.

  Conventionally, as a sealed bag for storing supplements of health supplements, various seasonings, cocoa, and other foods, there is a bag that has an occlusal chuck near the cut opening and has its end sealed. When used, there is provided a sealed bag for food that can be opened and closed repeatedly by opening from the cut end provided between the chuck and the end portion, opening the chuck, taking out the contents, and closing the chuck again. ing.

Further, in the bag with an occlusion tool that can be opened and closed inside the bag by two base film, the inner side of one base film located between the occlusion tool and the opening side seal is parallel to the occlusion tool. Along with forming the cutting guide part, the end part of the belt-like member continuous with the two cutting guide parts outside the one side end side seal part of the bag with the bite is cut together with the one base film There is a technique of a bag with a bite that can be opened. (See Patent Document 1)
Japanese Patent Publication No. 6-33092 (page 2-3), (FIG. 1)

  There are hermetically sealed food bags and techniques as described above, all of which are bags that can be stored again after opening. However, all have the following inconveniences and disadvantages. First of all, conventionally provided sealing bags are torn in a straight line from the cuts provided on either the left or right side of the end provided with a chuck that engages two males and females inside the opening, or are opened by scissoring. Since it is a bag, an opening formed by two films is cut out in a straight line. As a result, when trying to open the bag again, the cut end is cut in a straight line and the two films are in close contact with each other. There were drawbacks.

  Furthermore, the technology disclosed in Japanese Patent Publication No. 6-33092 discloses that one base film located between the bite and the opening-side seal in a bag with a bite that can be opened and closed inside the bag of two base films. Forming a cutting guide part parallel to the occlusal device provided on the inside, and the end of the belt-like member continuous with the two cutting guide parts on the outer side of one side end side seal part of the bag with the occlusal tool, It is a bag with a bite that can be cut and opened together with one base film, and when opened, the end of the band-shaped member that is continuous with the two cutting guide portions outside the one side end side seal portion described above It is a bag which cut | disconnects a part together with a base film, and opens it. However, with this opening method, the seal part at the end of the base film remains even after opening, so if you just tilt the bag when taking out the contents, it will be caught by the remaining seal part and you can not take it out smoothly. It is a technique of a bag with an occlusion tool that has the inconvenience and disadvantages such as having to fold it back and take out the contents or picking out the contents from the cut opening.

  The present invention has been made in order to eliminate the inconveniences and disadvantages described above. In claim 1, a chuck that is openable and closable inside a bag formed of a front film and a back film. The front film has an open edge near the chuck and the back film forms an extension of a certain length, and a cut is formed at the side of the folded portion in the middle of the extension. A food product that forms a cut-out opening in a stepped shape by folding and sealing with a peel-off adhesive part that can be peeled off and folded off with a sealing piece whose corner part is the non-adhesive part with the upper part as the sealing piece Use a sealed bag.

  According to the second aspect of the present invention, a step opening is formed in the same manner by providing perforations extending to the left and right instead of the cut provided in the folded portion of the extension.

  The sealed bag for food in this invention forms a sealing piece having a non-adhesive part on the upper part provided with a cut or perforation at the folded part in the middle of extending the back film on the opening side provided with the chuck, Since the sealing piece is configured to be sealed with a peelable adhesive part that can be peeled off by hand, when opening the pin, the corners of the sealing piece are pinched and peeled off, and the sealing piece is cut off from the cut or perforation. The opening can be formed in steps. Therefore, even when the opening is in close contact when the contents are taken out, it can be easily opened. Furthermore, since the back file side is slightly extended to form a dish shape, it is possible to provide a functionally easy-to-handle sealed bag that is not seen in the past, such as being able to take out while checking the number of foods when taking out.

  In a sealed bag that can be opened and closed many times, a food-sealed bag that can be formed in steps so that the cut-out opening can be easily opened.

1 is a partially peeled perspective view shown in FIG. 1, an enlarged vertical sectional view of an opening portion shown in FIG. 2, an enlarged development view showing an opening portion of FIG. 3, and the sealing of FIG. The reference figure which cut off the piece is shown.
The sealing bag 1 of Example 1 is a non-peeling material in which the left and right and lower portions where the back film 3 whose upper portion extends a certain length is positioned on the opposite side of the surface film 2 made of a synthetic resin material are firmly welded and cannot be peeled off. A bag body 5 is formed by the bonding portions 4, 4, 4, and a detachable chuck 7 as a male / female pair is provided inside the bag body 5 near the open edge 6, and the extended surface of the back film 3 The middle part between the end part and the chuck 7 part of the front film 2 is a folded part 8, and the upper part provided with triangular cuts 9 and 9 on the left and right sides of the folded part 8 is a sealing piece 10. Further, a sealing bag 1 is formed by folding back a sealing piece 10 having a non-adhesive portion 12 at its corner and adhesively sealing the open edge 6 with a peeling adhesive portion 12 that can be easily peeled off by hand. To do.

  The open edge 6 of the bag body 5 with the chuck 7 in the sealed bag 1 of Example 1 is folded and sealed with the sealing piece 10 with the back film 3 extended, and the bonding means contains pudding, tofu, etc. As it is used for lids of containers, it is easy to peel off by hand and has a peeling adhesive part 12 of the type that does not re-adhere, so that it is glued and sealed over the open edge 6 side. Since both corners of the stop piece 10 are non-adhesive portions 11 without an adhesive, when opening a bag containing food A, the corner portions of the non-adhesive portions 11 are pinched and peeled off as shown in FIG. Since the cut is made in a substantially straight line from the cut opening 9 of the folded portion 8 and the sealing piece 10 is cut off, as shown in FIG. 4, the opening of the front film 2 and the back film 3 is formed in a stepped shape. Therefore, the sealed bag 1 that can be easily opened even if the opening is in close contact is formed. In addition, although the cut 9 provided in the edge part of the folding | returning part 8 is provided in both sides, it does not interfere with only one side of one side.

The sealing bag of Example 2 is demonstrated with the expanded expanded view of the opening part shown in FIG.
The basic structure of the sealing bag 1 in the present embodiment is similar to the first embodiment, in which the chuck 7 is provided in the inside of the bag body 5 by the non-peeling adhesive portion 4 and the upper portion of the back file 3 is extended. In the middle folded portion 8, a perforation 13 extending to the left and right end portions is provided, and the sealing piece 10 having the corners with the upper portion of the perforation 13 as the sealing piece 10 and the non-adhesive portions 11, 11 is folded back. The sealing bag 1 that is adhesively sealed with the peeling adhesive portion 12 is configured.

  The sealing bag 1 in the second embodiment has the same basic configuration as that in the first embodiment, but the folded portion 8 of the sealing piece 10 is provided with perforations 13 extending to the left and right end portions. If the corner part of the sealing piece 10 is pinched and peeled off, the sealing piece 10 is linearly cut off from the perforation 13 part to form a stepped opening.

  In the sealed bag 1 for food according to the present invention, in both the first and second embodiments, the open edge 6 portion on the upper portion of the chuck 7 is folded back and the sealing piece 10 at the end of the back film 3 is folded back to the peeling adhesive portion 12. However, in the case of Example 1 type, there may be a method in which only the left and right and end portions of the sealing piece 10 excluding the cut portion 9 are sealed by the peeling adhesive portion 12. .

It is the perspective view which peeled partially which shows the sealing bag of Example 1 by this invention. 3 is an enlarged longitudinal sectional view showing a main part of opening of the sealing bag of Example 1. FIG. 3 is an enlarged development view showing an opening portion of the sealing bag of Example 1. FIG. It is a reference figure of the state where the sealing piece of Example 1 was cut off. 6 is an enlarged development view showing a main part of an opening part of the sealing bag of Example 2. FIG.
