Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) This invention relates to an adhesive fastener composed of a male type and a female type, one having an adhesive layer and the other being adhered to the adhesive layer. .

(Prior Art) At the opening of a plastic bag or the like, a fastener composed of a male mold having a fixed-length ridge and a female mold having a fixed-length fitting groove into which the ridge can be fitted. There is,
This has a drawback that the fitting force is weak in spite of requiring force because the ridge is merely press-fitted into the fitting groove. Therefore, an adhesive layer coated with an adhesive is provided at the opening of one sheet, release paper is stuck to this adhesive layer, and at the time of use, the release paper is peeled off, and the opening of the other sheet is overlaid and adhered. There is something to do.

(Problem to be Solved by the Invention) This adhesive layer type has a drawback that the release paper must be peeled off each time it is used, which is troublesome. Further, once the release paper is peeled off, the adhesive layer is easily stained by hand marks, dust or oil, and if it is soiled, the adhesive strength or fixing force of the adhesive layer is impaired. Therefore, this fastener is difficult to use repeatedly.

Therefore, the present invention solves the above-described problem by eliminating the need for release paper and providing a fastener that guards the adhesive layer so as not to be stained and that strongly adheres the attached sheet without being shifted. .

(Means for Solving the Problems) In this invention, one type is a female type fastener having an adhesive layer, and the other type is a male type fastener attached to the adhesive layer. Provided,
A female fastener which is provided adjacent to one side of the adhesive layer and provided with a ridge along the adhesive layer, and a ridge which is substantially the same height as the ridge and which is attached to the adhesive layer, has a predetermined length. And a male fastener provided.

Also, a ridge of the female fastener is provided adjacent to each side of the adhesive layer and along the adhesive layer, and the ridge of the male fastener to be attached to the adhesive layer is inserted between the two ridges. Sometimes it is a ridge.

(Function) Before use, the female fastener has an adhesive layer exposed on the outer surface. However, since the female fastener has a ridge adjacent to the side of the adhesive layer, when the female fastener is touched by hand, the ridge is formed. , And does not touch the adhesive layer. The same applies to the case where there is a ridge on one side of the adhesive layer and the case where there are ridges on both sides of the adhesive layer.

In addition, in order to fix the male fastener to the female fastener having a ridge on one side of the adhesive layer, one side of the ridge is applied to one side of the ridge of the female fastener, and the lower surface of the ridge is attached. When pressed against the adhesive layer, the ridges of the male fastener are stuck to the ridges of the female fastener and are attached to the adhesive layer. In order to fix the male fastener to the female fastener having ridges on both sides of the adhesive layer, insert the ridge between the two ridges of the female fastener and press the same to press the lower surface of the ridge. Is attached with a female fastener. In this case, as a result, the ridge of the male fastener is fitted between the two ridges of the female fastener, but these male and female fasteners are fixed to the female fastener. This is because the lower surface of the protrusion of the male fastener is attached to the adhesive layer of the mold fastener.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the present invention, in which a male fastener 3 provided with a ridge 2 having a rectangular cross section is provided along one side of a plastics sheet 1, and a plastics sheet is provided. 4, a narrow adhesive layer 5 formed by applying an adhesive is provided along one side, and the same as the above-mentioned ridge 2 on one side adjacent to and along the adhesive layer 5. A female fastener 7 having a ridge 6 of the same shape is provided.

In the case of the first embodiment, as shown in FIG. 2, the ridge 2 of the male fastener 3 is hooked on the ridge 6 of the female fastener 7, and the ridge 2 is pressed against the adhesive layer 5. As a result, the ridge 2 is attached to the adhesive layer 5 with one side locked to the ridge 6. Before the attachment, the adhesive layer 5 is exposed at the side of the ridge 6 of the female fastener 7. It does not directly hit the adhesive layer 5. Therefore, even before use, the adhesive layer 5 is not easily stained. When connecting the female fastener 7 and the male fastener 3, the ridge 6 serves as a guide, and the adhesive layer 5 is held while the ridge 2 is hooked on one side of the ridge 6.
, The ridges 2 can be securely attached without removing the ridges 2 from the adhesive layer 5, and the sheets 1 and 4 do not shift. In order to peel off the male fastener 3 from the female fastener 7, the outer ends of the sheets 1 and 4 of the ridges 2 and 6 can be easily peeled off by holding them by hand.

FIGS. 3 and 4 show a second embodiment of the invention, in which a plastic zipper 10 having a rectangular ridge 9 is provided along one side of a plastics sheet 8 and a plastics sheet 11 is provided. A narrow adhesive layer 12 formed by applying an adhesive is provided along one side of the adhesive layer.
And a female fastener 14 having ridges 13, 13 of the same shape and size as the ridges 9 is provided along the adhesive layer 12.

In the case of the second embodiment, as shown in FIG. 4, the ridge 9 of the male fastener 10 is replaced with the two ridges 13 of the female fastener 14,
13 and press the ridge 9 against the adhesive layer 12 between them. As a result, the ridge 9 is attached to the adhesive layer 12 in a state of being fitted between the two ridges 13.

Before attaching, two ridges of female fastener 14 are used.
Since the adhesive layer 12 is located in the concave portion between 13 and 13, even if the hand touches the relevant portion, the hand hits each of the two ridges 13 and does not directly hit the adhesive layer 12.

Further, as in the first embodiment, when the ridges 9 of the male fastener 10 are attached to the adhesive layer 12 of the female fastener 14, they may be inserted between the two ridges 13, 13, and these ridges may be inserted.
13 and 13 can be used as guides for easy and reliable attachment.

FIG. 5 shows a third embodiment of the present invention. This third embodiment has substantially the same structure as that of the second embodiment, except that each ridge 13 'of the female fastener 14' is provided. The thin tongue pieces 15 and 15 are horizontally projected from the upper green surface facing each other, thereby covering the adhesive layer 12 'between these ridges 13' and 13 'to prevent dust and dust from adhering. Things. Since these tongue pieces 15, 15 are thin, respectively, they are easily broken when inserting the ridge 9 'of the male fastener 10' between the ridges 13 ', 13', so that they do not become an obstacle.

The adhesive fastener of the present invention can be used at the opening of a bag made of plastics or the like and other appropriate places, and as shown in FIG. A female fastener 18 is provided to connect the sheets 16 together, or as shown in FIG. 7, a male fastener 20 is provided on both sides of a large number of sheets 19, and a connecting band 22 having female fasteners 21 on both sides. By each of these sheets
19 can also be linked.

Although FIGS. 6 and 7 show the adhesive fastener of the second embodiment, the adhesive fastener of the first or third embodiment can be used.

Further, in each of the above-described embodiments, the ridge has a rectangular cross section, but the cross sectional shape is not limited to this. In each of the above embodiments, when the male fastener is peeled from the female fastener, peeling charging occurs, and these portions are charged, and dust and dust easily adhere to the adhesive layer due to static electricity. Therefore, if antistatic films are formed on the female fastener and the male fastener in each of the above embodiments, no peeling charging occurs when these are peeled off. Therefore, dust and dust are less likely to adhere to the adhesive layer.

(Effects of the Invention) This invention has the above configuration, and has a ridge adjacent to the adhesive layer and along the adhesive layer on the side of the adhesive layer of the female fastener. There is almost no direct contact with the object, so that hand marks, dust, dust, oil and the like are hardly attached. Therefore, it does not stain the adhesive layer. Therefore, no release paper is stuck, and it is not necessary to peel off the release paper each time to close the fastener. Moreover, since the adhesive layer is not stained, it can be used repeatedly. When closing this adhesive fastener, the male zipper ridge should be applied to the female zipper ridge and pressed against the adhesive layer on the side, and the ridge serves as a guide to secure the female fastener adhesive layer. And a male fastener can be stuck easily. In addition, since the ridges of the male fastener are locked to the ridges of the female fastener at the time of sticking, the adhesive surface is firmly fixed without sideways, and the fastener is not opened unnecessarily. Therefore, even if the pressure-sensitive adhesive layer is narrow, it has a fixing force.

In addition, the female fastener having the adhesive layer on both sides of the adhesive layer has the adhesive layer at the bottom of the concave portion formed between the two projections, so that hands or other objects may come into contact with the adhesive layer. Less and not dirty. Also, when this fastener is joined, it is more strongly joined than one having a ridge on one side.
