Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slider of a bag body formed so as to lock or disengage a fastener portion formed in an opening of a bag body such as a case formed of a material such as polypropylene or vinyl chloride. .

[0002]

[Prior art]

 As shown in FIG. 7, a conventional case which is the background of the present invention is formed by continuously forming a first main body and a second main body which form a case main body 1 through a bottom portion, and a first main body and a second main body which are opposite to the bottom portion. A pair of rail-shaped fasteners 1a and 1b are provided on the upper end edges of the first main body and the second main body on the opening side, and the pair of fasteners 1a and 1b is opened and closed by a slider 5.

[0003]

[Problems to be solved by the device]

 However, in the case of such a set of fasteners 1a and 1b, the hermeticity is poor. Therefore, in order to improve the confidentiality, it is conceivable to form two sets of fasteners in the opening of the case body as disclosed in, for example, Japanese Utility Model Publication No. 47-3452, but simply provide two sets of fasteners. However, since there are two fasteners in one opening, it takes time to open and close, and the user may dislike it, and if the fastener is forgotten to be closed, the confidentiality is not expected. I cannot achieve my purpose.

Therefore, the main object of the present invention is to provide a bag slider that can completely close two sets of fasteners in one operation.

[0005]

[Means for Solving the Problems]

 This invention is formed so as to engage or disengage the fastener portion across the fastener portion formed in the opening portion of the bag body, and the opening portion having a pair of fastener portions formed therein. A horizontal bridge is formed so as to extend over the horizontal cross section, and a pair of first lateral pressure sections are formed to project from the horizontal bridge at appropriate intervals. The second lateral pressure portion is formed so as to project from the end opposite to the portion, and the second lateral pressure portion projects from the lateral bridge portion so as to be located between the fastener portions at least between the first lateral pressure portions. Is formed, the first lateral pressure portion is located outside the first fastener portion formed closer to the opening of the bag body, and the second lateral pressure portion is closer to the bag body than the first fastener portion. Formed so as to be located outside the second fastener portion formed at a position farther from the opening, Body which is a slider.

[0006]

[Action]

 A second lateral pressure portion is continuously formed from an end of the first lateral pressure portion opposite to the lateral bridge portion, and the first lateral pressure portion is formed at a position closer to the opening of the bag body. And the second lateral pressure portion is formed outside the second fastener portion formed at a position farther from the opening of the bag body than the first fastener portion. The first lateral pressure portion is pressed and locked to close the first fastener portion, and the second lateral pressure portion is pressed and locked to close the second fastener portion.

[0007]

[Effect of device]

 A second lateral pressure portion projecting continuously is formed at an end of the first lateral pressure portion opposite to the lateral bridge portion, and the first lateral pressure portion is formed at a position closer to the opening of the bag body. It is located outside the first fastener part, and the second lateral pressure part is located outside the second fastener part formed at a position farther from the opening part of the bag body than the first fastener part. Since it is formed in one, both the first fastener part and the second fastener part can be closed by one operation. Further, between the first lateral pressure portions, since the protrusions are formed so as to be located between the fastener portions so as to protrude from the lateral bridge portion, the first fastener portion can be disengaged and opened.

Therefore, the person using the bag never forgets to close both the first fastener part and the second fastener part, and both the fasteners can be opened and closed very easily. You can keep it even more.

The above objects, other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.

The case 10, which is a bag body, has the same structure as the case body shown in FIG. 7, and includes a case body 12 having a front rectangular shape formed of a relatively soft plastic such as polypropylene or transparent vinyl chloride. . The case main body 12 has a front main body 14 having a rectangular shape and a first main body 14 forming a bottom portion of the case main body 12, and a first main body 14 having substantially the same shape as the first main body 14 via a longitudinal lower edge of the first main body 14. Two main bodies 16 are continuously formed. That is, the bottom of the case body 12 is formed with the boundary portion between the first main body 14 and the second main body 16.

The first main body 14 and the second main body 16 have a pair of fasteners made of a relatively soft material such as vinyl chloride at the end edges of the first main body 14 and the second main body 16 on the side of the opening 18 similar to those forming the case main body 12. The base materials 20a and 20b are continuously welded, and the first fastener portion 22 is formed on the fastener base material 20a that is continuously formed on the first main body 14, and the case is larger than the first fastener portion 22. A second fastener portion 24 is formed on the fastener base material 20 a at a position farther from the opening 18 of the fastener 10.

The first fastener member 26 forming the first fastener portion 22 formed on the opening 18 side of the first main body 14 has a substantially L-shaped linear projection at the longitudinal edge of the fastener base material 20a. The first fastener member 30 that is formed by protruding one pair of parallel strips and that forms the first fastener portion 22 formed at the edge of the second main body 16 on the opening 18 side is the opening of the fastener base material 20b. Three projections 32a, 32b, and 32c are continuously formed so as to be located inside the end edge on the side of the portion 18 and project from the connecting member 34. That is, each of the ridge 32a and the substantially L-shaped ridges 32b and 32c is connected to the connecting member 34 at a constant interval, and the connecting member 34 is provided at the end of the second main body 16 on the opening 18 side. The base material 20b is bonded to and integrated with the opening side edge of the base material 20b. That is, the first fastener member 26 and the first fastener member 30 are locked by the protrusions 28 of the first fastener member 26 and the protrusions 32a, 32b, 32c of the first fastener member 30. 1 The fastener portion 22 is formed so that it can be closed.

On the other hand, the second fastener portion 24 is fitted to the second fastener member 36 provided with a rail body having a substantially T-shaped cross-section having a convex portion on one part and the protrusion of the second fastener member 36. A pair of second fastener members 38 each having a fitting U-shaped section and having a substantially U-shaped cross section are configured. That is, one second fastener member 38 is formed on the fastener base material 20 a on the opening 18 side of the first main body 14, and the other second fastener member 36 is formed on the second main body 16. The fastener base material 20b is formed on the opening 18 side.

Next, the first fastener part 22 and the second fastener part 24 are locked or disengaged across the first fastener part 22 and the second fastener part 24 formed in the opening 18 of the case 10. The slider 50 thus formed will be described. The slider 50 is integrally molded of synthetic resin, and as shown in FIGS. 3 to 6, an opening portion in which a pair of first fastener portions 22 and another pair of second fastener portions 24 are formed. A horizontal bridge portion 52 is formed so as to straddle over 18, and a pair of first lateral pressure portions 54a, 54b are formed to project from the horizontal bridge portion 52 at regular intervals. Second lateral pressure portions 56a, 56b are formed continuously from the ends of the pressure portions 54a, 54b on the side opposite to the lateral bridge portion 52 at a constant interval.

The distance between the pair of first lateral pressure portions 54a and 54b is wider than the distance between the pair of second lateral pressure portions 56a and 56b. The first fastener part 22 is larger than the second fastener part 24, and the ridges 28 and the ridges 32a, 32b, 32c that form the first fastener members 26, 30 are the second fastener parts 36, It is formed corresponding to the fact that it is formed higher than 38. Further, between the second lateral pressure portions 56a, 56b and the first lateral pressure portions 54a, 54b, the second lateral pressure portion 56a, the first lateral pressure portion 54a, the second lateral pressure portion 56b, and the first lateral pressure portion 56b. Connecting portions 58a and 58b are formed to connect the lateral pressure portion 54b, respectively. The connecting portions 58a and 58b are arranged so that the slider 50 does not come off from the first fastener portion 22 toward the opening 18 side. The step portions 60a and 60b are formed to be narrower than the space between the first lateral pressure portions 54a and 54b.

Between the first lateral pressure portion 54a and the first lateral pressure portion 54b, a protrusion having a head portion 62a whose width becomes narrower vertically inward from the inner surface of the lateral bridge portion 52. When the slider 62 is formed by projecting and the slider 50 is slid to open the opening 18, the head portion 62a locks the protrusion 28 of the first lateral pressure portion and the other protrusions 32a, 32b, 32c. Is formed to disengage. A grip portion 64 is formed on the outer surface of each of the first lateral pressure portions 54a and 54b so as to be caught in the sliding direction of the slider 50 so as not to slip when the slider 50 is picked by a finger. Therefore, in the slider 50, the first lateral pressure portions 54a, 54b are located outside the first fastener portion 22 formed closer to the opening 18 of the case 10, and the second lateral pressure portion 56a and 56b are fitted into the opening portion 18 so as to be located outside the second fastener portion 24 formed at a position farther from the opening portion 18 of the case 10 than the first fastener portion 22.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and various modifications can be made.
