Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Overview)
FIG. 1 shows a storage body 31 according to the first embodiment. The storage body 31 is a bag body in which two sheets of flexible sheets, a front side sheet 32 and a back side sheet 33, are bonded together by heat welding or the like. As the front side sheet 32 and the back side sheet 33, a sheet mainly composed of a synthetic resin provided with a single layer or a plurality of layers can be preferably used, and a composite material including a metal layer and a paper layer as necessary. The sheet | seat made from may be sufficient. The shape of the storage body 31 can be variously changed and implemented, and may have a collar part, may have a bottom sheet, and a part thereof is a molded product having high rigidity. It may be configured. The front side sheet 32 may be constituted by a separate sheet body from the back side sheet 33, and may be a sheet in which a continuous sheet is folded and arranged on the front and back sides.

An opening 34 is formed on at least one of the front side sheet 32 and the back side sheet 33 (in this example, the front side sheet 32) among the same side sheets constituting one surface of the storage body 31. ing. The fixing portion 14 of the first fastener half 11 and the fixing portion 24 of the second fastener half 21 are bonded to the front side sheet 32 by thermal welding or the like on both the upper and lower sides with the opening 34 interposed therebetween. Yes. The first fastener half 11 and the second fastener half 21 constitute a fastener 10 that can be opened and closed by detachably fitting a male and female fitting portion 13 and a male and female fitting portion 23.

Hereinafter, the longitudinal direction of the 1st fastener half part 11 and the 2nd fastener half part 21 which comprise the fastener 10 is called the left-right direction (or horizontal direction), and the width direction of the 1st fastener half part 11 and the 2nd fastener half part 21 is shown. Are referred to as the vertical direction (or vertical direction), but these only indicate a relative positional relationship and do not specify an absolute position.

(About the second fastener half 21)
First, the second fastener half 21 will be described. The second fastener half 21 is the same as that used for an ordinary synthetic resin fastener, and includes a base 22 and a male / female fitting 23 provided on the back side of the base 22. The entire front surface side or a part in the width direction of the male / female fitting portion 23 constitutes a fixing portion 24, and the fixing portion 24 and the back side of the front side sheet 32 are fixed by adhesion such as heat welding.
In this example, the second fastener half 21 is disposed below the opening 34, but may be disposed above.

(About the first fastener half 11)
Next, the first fastener half 11 is a synthetic resin fastener half that fits into the second fastener half 21, and includes a base 12 and a male-female fitting 13 provided on the front side of the base 12. Is provided. The male / female fitting part 13 is detachably fitted to the male / female fitting part 23 of the second fastener half 21 and is substantially at the same position in the vertical direction as the male / female fitting part 23 of the second fastener half 21. Provided at the bottom of the opening 34. In addition, when the 2nd fastener half part 21 is arrange | positioned above the opening part 34, the male-female fitting part 13 of the 1st fastener half part 11 is also arrange | positioned above. In the example of FIG. 1, the male and female fitting portion 23 of the second fastener half 21 is implemented as a male fitting portion of a ridge, and the male and female fitting portion 13 of the first fastener half 11 is implemented as a female fitting portion. As shown in FIG. 2 (A), the male and female can be reversed, and the male and female fitting portions of the fastener can be changed variously, such as a shape in which a plurality of ridges and grooves are fitted together. Can be implemented.

The base portion 12 of the first fastener half 11 is formed over the opening portion 34 in the vertical direction, and the fixing portion 24 is formed above the opening portion 34. The fixing portion 14 of the first fastener half 11 is formed on the front end surface of the convex portion 15 protruding to the front side, and is fixed to the back side of the front side sheet 32 by adhesion such as heat welding. . In this example, in a state where the male / female fitting portion 13 of the first fastener half 11 and the male / female fitting portion 23 of the second fastener half 21 are fitted, the fixing portion 14 of the first fastener half 11 and the second The convex part 15 protrudes in the front side so that the fixing part 24 of the fastener half part 21 becomes substantially the same height. As a result, as will be described later, the opening operation can be performed very smoothly, and thermal welding to the front side sheet 32 can also be reliably performed.

The base portion 12 of the first fastener half 11 includes an intermediate portion 16 between the male and female fitting portion 13 and the fixing portion 14. The intermediate portion 16 is a concave portion recessed on the back side as compared with the male-female fitting portion 13 and the fixing portion 14 (convex portion 15). As a result, a pushing space 39 is formed between the male and female fitting portion 13 and the fixing portion 14 (convex portion 15) between the intermediate portion 16 and the front side sheet 32. An unsealed portion 34 is formed on the front side sheet 32 that is located on the front side of the intermediate portion 16 and the pushing space 39.

(About the opening part 34)
The unsealing part 34 is formed on the front sheet 32 and is sandwiched between the fixing part 14 of the first fastener half 11 and the fixing part 24 of the second fastener half 21 in the vertical direction. Is formed. The opening part 34 includes a longitudinal opening part 35 extending in the left-right direction and an opening start part 36 formed at an appropriate position (in this example, the center). In this example, the longitudinal opening portion 35 is a perforation formed in the front side sheet 32, and the opening start portion 36 is a cut portion formed in the front side sheet 32. It is appropriate to implement the cut portion as having a right and left length of about 10 to 40 mm with a size that allows a fingertip to enter. The cut portion only needs to be cut in a linear shape, and its vertical width is 0 mm. However, it can be implemented as a vertical width of about several mm to 10 mm.

(About opening operation)
When opening, first, the finger f is pushed in from the opening start portion 36 and inserted into the space 39. In this example, the opening start portion 36 is a cut portion that has been cut in advance, and the intermediate portion 16 is a concave portion as described above, so that the finger f can be pushed into the back side without difficulty. Then, by moving the inserted finger f to the left and right, the longitudinal opening 35 of the perforation can be easily broken. Of course, the longitudinal unsealing part 35 may be broken in the manner of pulling up and down by picking the front side sheet 32 with a finger inserted into the unsealing start part 36. In any case, by opening the opening start part 36 into the pressing space 39, the opening from the opening start part 36 can be performed very easily.

(About manufacturing method)
The housing 31 can be manufactured very easily. Conventionally, this type of fastener 10 includes a first fastener half 11 and a second fastener half 21 fitted to a front side sheet 32 continuously fed in a web shape. The fixing part 14 of the half part 11 and the fixing part 24 of the second fastener half part 21 are bonded and fixed by heat welding or the like. In the embodiment of the present invention, it is only necessary to form the opening part 34 (longitudinal opening part 35 and opening start part 36) on the front side sheet 32 with a push-off device or the like prior to this adhesive fixing. In this way, bonding is performed such that the fixing portion 14 of the first fastener half 11 and the fixing portion 24 of the second fastener half 21 are positioned on both the upper and lower sides of the opening portion 34 formed in advance. Therefore, it is possible to manufacture at low cost without increasing the number of manufacturing steps.

(Second Embodiment)
FIG. 3A shows a second embodiment. In the previous embodiment, the longitudinal opening 35 of the opening 34 was perforated, but in this example, the longitudinal opening 35 has a straight cut property utilizing the properties of the sheet. In other respects, the description of the previous embodiment can be applied to other points.

In this embodiment, among the sheets constituting the storage body 31, at least the front side sheet 32 includes a stretched film having directionality. In this type of sheet, it exhibits a straight cut property in one direction which is the longitudinal direction of stretching, and the easy cut direction 40 showing this straight cut property is a direction along the longitudinal direction of the fastener (left-right direction). ), The longitudinal opening portion 35 is formed by arranging the front side sheet 32. Therefore, unlike the previous example, in this embodiment, the longitudinal opening portion 35 has a configuration that cannot be distinguished from other portions of the front sheet 32, but the opening start portion 36 is formed by a cut portion or the like, By pushing the finger f from the opening start portion 36 into the insertion space 39 and moving the inserted finger f left and right as described above, the longitudinal opening portion 35 is easily broken in the easy-cut direction 40 indicating straight cut performance. Can do.

Although illustration is omitted, the longitudinal opening 35 may be a half cut that is a concave groove formed from the surface of the front sheet 32 to the middle in the thickness direction. Further, when the front side sheet 32 is a sheet obtained by laminating a plurality of films, as a sheet provided with a weak line in which a film on the surface or inside thereof is cut in advance or a perforation is formed on the film. It is also possible to form the longitudinal opening 35 by the weak line.
Thus, the longitudinal opening part 35 can be implemented by changing to various means that can be easily cut in the direction along the longitudinal direction of the fastener 10.

(Modification of opening start unit 36) FIG. 3B shows a modification of the opening start unit 36. In the previous two embodiments, the opening start portion 36 is a cut portion, but in this example, the opening start portion 36 is configured by a perforation. The description regarding any of the previous embodiments can be applied. In the example of FIG. 3B, the longitudinal opening portion 35 is also perforated. However, the perforation of the opening start portion 36 can be opened with a smaller force than the perforation of the longitudinal opening portion 35. It is desirable to increase the number of eyes or increase the width. In this way, the opening start portion 36 can be opened with a force smaller than that of the longitudinal opening portion 35, or can be implemented as a pre-opened cut, so that it becomes the weakest pushing portion. It is preferable in terms of ease of opening and preventing unnecessary opening of the front side sheet 32. However, it is also possible to configure the longitudinal opening portion 35 and the opening start portion 36 with the same perforation on the condition that they can be broken with the finger f (see FIG. 3C). In that case, there is no distinction between the longitudinal opening part 35 and the opening start part 36, and the opening can be opened from any part of the opening part 34, but the opening position is indicated by an arrow or the like so that the user does not get lost. It can also be shown. It is desirable to provide such an indication of the opening position even in other examples.

FIG. 3D employs an example of the second embodiment in which a perforation is adopted for the opening start portion 36, and the easy-cut direction 40 showing the straight cut property for the longitudinal opening portion 35 is the longitudinal direction of the fastener 10. It is a thing. FIG. 3 (E) is an example in which the opening start portion 36 is arranged not at the center of the storage body 31 but at the left and right ends of the front side sheet 32. FIG. 3 (F) shows a plurality of opening start portions 36. This is an example of arrangement. Although illustration is omitted, the longitudinal unsealing portion 35 can be implemented with various modifications such as providing a plurality of the longitudinal opening portions 35 in parallel.

Thus, about the structure of the opening part 34 (longitudinal opening part 35, opening start part 36), it can change and implement variously, such as the structure, number, and magnitude | size, It can implement in various combinations. .

(Modification Example of First Fastener Half 11) As described above, the convex portion 15 of the first fastener half 11 is substantially equal to the thickness of the male and female fitting portion 13 and the male and female fitting portion 23 in the fitted state. Although it is most desirable to project the height so that the fixing portion 14 at the tip thereof and the fixing portion 24 of the second fastener half 21 are substantially the same height, as shown in FIG. In addition, it is also possible to carry out with a slight difference between the heights of the two. In the example of FIG. 2 (B), the height of the convex portion 15 is set to about one half of the thickness of the male and female fitting portion 13 and the male and female fitting portion 23 in the fitted state. The degree is acceptable. Moreover, it is not impossible to carry out the fixing portion 14 and the intermediate portion 16 at the same height without providing the convex portion 15 at all. However, it is possible to improve the pushing of the opening portion 34, and to the front side sheet 32. From the viewpoint of achieving good adhesion such as heat welding, it is desirable to provide the convex portion 15 for implementation.

(About Figure 2 (C))
Further, in the above-described embodiments, the lengths of the bases 12 and 22 of the fastener halves 11 and 21 to the lower side of the lower end in the figure are substantially the same length. Good. In particular, as shown in FIG. 2C, it is also preferable that the base 12 of the first fastener half 11 extends longer than the base 22 of the second fastener half 21. In this way, in the width direction of the fastener 10 (vertical direction in FIG. 2), the extension portion 17 is provided at the end portion of the base portion 12 of the first fastener half portion 11, and this extension portion 17 is connected to the second fastener half portion 21. The base portion 22 protrudes in the width direction. Thus, when the base portions 12 and 22 of the fastener halves 11 and 21 are thermally welded to the front side sheet 32 at the fixing portions 14 and 12, the extension portion 17 is also lightly heat welded to the front side sheet 32. A temporary joint 18 is formed. In the figure, although the thickness of the temporary joining portion 18 is drawn large, actually, the front side sheet 32, the extension portion 17 and the like naturally bend in the thickness direction. It may be the same as the parts 14 and 24. However, the thickness of the extension portion 17 is different from that of the other fixed portions 14 and 24 (for example, the thickness is increased to ensure that the temporary joining is performed, or the thickness is reduced to adjust the strength of the temporary joining. As well).

In this way, by providing the temporary joining portion 18 by the extension portion 17, even if the male and female fitting portions 13, 23 may come off during storage or transfer of the storage body 31 storing the objects to be stored, There is a high possibility that communication between the inside and outside of the storage body 31 can be prevented by the joint portion 18.
On the other hand, when opening, when the male and female fitting portions 13, 23 are removed from the opening portion 34, the base 12 of the first fastener half 11, the extension portion 17, and the front side sheet 32 are Since it is pulled strongly to the left and right in the drawing so as to be separated from each other, the temporary joining portion 18 of the extension portion 17 is removed, and the inside and outside of the container 31 can be communicated.
Accordingly, it is desirable that the temporary joint portion 18 of the extension portion 17 has an appropriate area so as not to be inadvertently removed but to be removed when intentionally opened. Specifically, the extension portion 17 may have a length in the width direction (up and down direction in the drawing) of about 3 to 10 mm, but the present invention should not be understood to be limited to this value.

Further, the material may be devised so that the fixing strength to the front side sheet 32 is made stronger and the fixing portions 14 and 24 are made stronger and the extension portion 17 is made weaker. For example, the entire fastener halves 11 and 12 including the extension 17 are formed of a material having a high welding temperature such as polypropylene, and a material having a low welding temperature such as polyethylene is formed on the front surface of the both fixing portions 14 and 24. Arrange them by laminating films. Then, at least the back side of the front side sheet 32 may be made of a material having a low heat welding temperature, and may be weakly bonded by thermocompression bonding at a temperature that is a polyethylene welding temperature and lower than the polypropylene welding temperature.

(About Figure 4)
When the storage body 31 according to the present invention is industrially mass-produced, a continuous sheet 51 shown in FIG. Each housing 31 can be manufactured while housing or without housing. The continuous sheet 51 includes two front side sheets 32 that can form the storage body 31 (or two cylindrical sheets that are arranged on the back side of the front side sheet 32 with right and left side seals if necessary, and are formed into a cylindrical shape. A plurality of sheets may be continuously arranged in the longitudinal direction (vertical direction in FIG. 4). In this example, the storage body 31 shown in FIG. 1 can be continuously produced. However, the storage body 31 according to another embodiment may be used.
In the continuous sheet 51, the above-mentioned fasteners for opening and closing are arranged at equal intervals for each storage body 31, and are fixed by fixing portions 14 and 24. And the opening part 34 (the longitudinal opening part 35 and the opening start part 36) is formed in the front side sheet | seat 32 at equal intervals between the fixing | fixed parts 14 and 24. FIG. The continuous sheet 51 is usually wound and transferred in a roll shape, and in the process of completing the storage body 31, a seal on the top of the bag is placed at a boundary portion 52 between the storage body 31 and the storage body 31. The bottom seal is applied and cut to complete the storage bodies 31 one by one.
