  With the gusset bag described in Patent Document 1, it has become possible to provide a gusset bag with a sealing chuck that maintains high sealing performance. And since the position of a chuck | zipper is installed on a positioning seal, the opening part of a gusset bag will be formed through the positioning seal which welded the upper end part of the horizontal gusset part. Therefore, when the stored item is stored in the bag through the opening, the upper end portion of the horizontal gusset portion does not hinder at all.

  However, so far, no self-standing square bottom bag with a chuck suitable for display of goods using a gusset bag with a sealed chuck has been proposed. For example, bags made of fruit and bags made of synthetic resin that pack confectionery such as cookies could all be put together, but they could not be displayed efficiently. .

  Moreover, these conventional bags for displaying products may be closed with a string-like tightening member that closes the opening. In this case, a lot of time and effort is required for bagging the product. Moreover, although heat sealing may be carried out after goods storage, since it is necessary to introduce special machines, such as a heat sealer, it is not suitable for small-scale bagging.

A fixed end 3A is provided at one end of the sealing chuck 3, and the one end is fitted in advance. It is provided to be fixed in a state.

  In the second means, the lower edge of the sealing chuck 3 is configured to be close to the upper end edge of the horizontal gusset part 4, and the upper end edge of the horizontal gusset part 4 is the above-mentioned when the sealing chuck 3 is fitted. The sealing chuck 3 is configured to be covered with a lower edge.

  In the third means, one of the opening edge portions 7 is extended upward to form a header 6, and a product display surface 8 for displaying the stored product is provided on the header 6.

  As in claim 1 of the present invention, the height of the front film 1 and the rear film 2 is formed to be higher than the height of the horizontal gusset part 4, the upper part of the horizontal gusset part 4, and the front film 1 and the rear film 2. The sealing chuck 3 is welded inside to form an opening edge 7 that can be freely opened and closed, and one end of the sealing chuck 3 is fixed in a fitted state in advance, so that the sealing chuck 3 is opened with the opening edge 7. Then, one side of the opening is greatly opened. As a result, the stored items can be stored from the wide opening, and the bagging operation of the product becomes extremely easy.

  Moreover, since one end portion of the sealing chuck 3 is fixed in a fitted state in advance by the fixed end portion 3A, when the sealing chuck 3 having a wide opening is fitted to each other, one end that has been fitted in advance. Since the portions opened from the portion can be sequentially fitted, the fitting operation of the sealing chuck 3 becomes extremely easy. As described above, the bagging operation of the product and the fitting operation of the sealing chuck 3 are facilitated, so that a bag suitable for storing an extremely large number of types of products can be provided.

  As in claim 2, the lower edge of the sealing chuck 3 is configured to be close to the upper edge of the horizontal gusset 4, and the upper edge of the horizontal gusset 4 is fitted to the sealing chuck 3 when the sealing chuck 3 is fitted. By being configured to be covered at the lower edge, even when the sealing chuck 3 is not welded to the lateral gusset portion 4, the opening portion can be covered. As a result, it is a self-supporting square bottom bag with a chuck suitable for storing various products such as fruits and confectionery.

  Since the header 6 is formed by extending one of the opening edges 7 upward as in claim 3 and the product display surface 8 for displaying the stored product is formed on the header 6, the chuck of the present invention The contents of the products stored in the self-supporting square bottom bag are easy to understand, and it is possible to increase consumers' willingness to purchase.
