Abstract

(57) [Summary] [Structure] A zipper bag having a structure in which a male part and a female part are engaged with each other. The female part has protrusions on both sides, and the male-side protrusions correspond to the female parts. It is a bag with a zipper arranged so that it may be located between a part and a female part side projection part. [Effect] By inserting the male-side protruding portion between the female portion and the female-side protruding portion, accurate alignment can be achieved. Further, after the alignment, the male-side protruding portion acts as a guide for the female-side protruding portion, so that it is possible to prevent a deviation when sealing. Furthermore, since it is not necessary to make the forming locations of the male-side protruding portion and the female-side protruding portion so precise, there is an advantage that the manufacturing is easy.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the chuck structure of a bag with a chuck having a structure in which a male part and a female part are engaged with each other.

[0002]

[Prior art]

 A chuck having a structure in which the male part and the female part are engaged with each other is often attached to the opening of the bag as an inexpensive and easy resealing means. However, the conventional chuck structure consists of only a male part and a female part, so initial positioning was difficult, and even during the process, the engagement was likely to shift and accurate sealing was difficult. In addition, it was difficult to know if the meshing was good because the width of the chuck part was narrow.

In order to solve these problems, for example, JP-A-55-68056 proposes a bag with a zipper in which a male part and a female part have different colors. In this case, since the colors of the male part and the female part are different, there is an advantage that the engaged state can be easily confirmed visually. However, the structure of the male part and the female part is the same as the conventional structure, and the drawbacks such as easy misalignment were the same as before. In addition, there is a problem that it takes a lot of time and unnecessary operations to redo the operation of applying the feedback and sealing when they are not properly meshed.

On the other hand, JP-A-59-136160 proposes a chuck structure in which ribs are attached to both sides of a male part. In this case, as long as the female portion is inserted between the ribs, the male portion naturally engages with the female portion, which has an advantage that the sealing can be easily and accurately performed. However, if the distance between the rib and the male part is too large, the above effect cannot be expected, and if it is too close, the female part cannot be inserted between the ribs, so it is necessary to place the rib in an appropriate position accurately. There was a manufacturing problem. Moreover, in this case, the width of the entire chuck structure is not so wide, so that it was not sufficient to make the initial engagement and the correct positioning when sealing.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to provide a zipper bag having a structure capable of surely sealing when the male part and the female part of the chuck are engaged with each other to seal the bag.

[0006]

[Means for Solving the Problems]

 According to the present invention, in a zipper bag having a structure in which the male part 21 and the female part 22 are engaged with each other, the male part 21 and the female part 22 have protrusions on both sides thereof, and the male part-side protrusion 11 Is provided so that it is located between the corresponding female part 22 and female part side projection part 12, respectively.

The present invention will be described below with reference to the drawings. First, the male part 21 and the female part 22 that form the chuck may have the same structure as that conventionally proposed, and there is no particular limitation as long as they are intimately engaged with each other. Further, it has projections formed on both sides of the male part 21 and the female part 22, respectively. The male-side protruding portion 11 is arranged so as to be located between the female portion 22 and the female-side protruding portion 12. Therefore, the distance L between the male-side protrusion 11 and the male portion 21 needs to be slightly shorter than the distance M between the female-side protrusion 12 and the female portion 22.

[0008]

[Action and effect]

 Therefore, when the zipper bag of the present invention is sealed, it is difficult to mate the male part 21 and the female part 22 with each other, but the male part side projection part 11 is placed between the female part 22 and the female part side projection part 12. Can be easily inserted, and when the protrusion is included, the width of the entire chuck structure is considerably wide, so accurate alignment can be achieved. Further, after the alignment, the female-side protruding portion 12 acts as a guide for the male-side protruding portion 11, so that deviation when sealing can be prevented and accurate sealing can be performed. Furthermore, since it is not necessary to make the forming locations of the male-side projection 11 and the female-side projection 12 very precise, there is an advantage that the manufacturing is easy.
