Description

[0001]
[Industrial application fields]
The present invention relates to a finger sack used when a sanitary tampon is inserted into a vagina.
[0002]
[Prior art]
Conventionally, finger sacks used when inserting a sanitary tampon into the vagina are known. For example, in Japanese Utility Model Publication No. 2-102221 and Japanese Examined Patent Publication No. 4-39335, two resin films are superposed and heat-sealed at the front end portion and the left and right side portions, and along the heat-welded portion. A finger sack is disclosed in which a finger insertion opening is formed on the opposite side of the tip portion. A general sanitary tampon is a non-woven fabric made of water-absorbing fibers, which is compression-molded into a cylindrical shape, and has a drawer string at its rear end.
[0003]
[Problems to be solved by the invention]
The heat fusion part of the conventional finger sack has a problem that it is generally solidified and has a poor touch. In addition, burrs remain on the melted part, which not only contributes to the poor touch, but also tends to get tangled in the fiber tampon body and the drawer string extending from it, and quickly from the tampon after insertion There is a problem that it becomes an obstacle when releasing a finger. Therefore, it is desirable for this type of finger sack to have as few heat-fused portions and fused portions as possible.
[0004]
This invention makes it a subject to solve the problem of the said prior art by bend | folding a heat-fusible plastic film in two, and making the bending curve become the front-end | tip part of a finger suck.
[0005]
[Means for Solving the Problems]
In this invention, the heat-fusible plastic film is folded in two and overlapped, and the film overlapped by two parallel heat-sealing lines intersecting the folding line is fused, A finger sac in which a finger insertion part having an opening on the opposite side of the folding line is formed at a portion surrounded by the thermal fusion line, and the opposite side edge of the folding line is an extension of the thermal fusion line The opposite side edge is formed by a relatively free edge and a far free edge that are relatively close to the opening and the folding curve, by folding the film so that it is displaced in the direction of and has the heat Chakusen peelably bonded to the mount via a Rutotomoni, sanitary tampon insertion, characterized in that said even in some distant free edge are peelably bonded to the base sheet There is a finger sack.
[0006]
As a preferred embodiment, the present invention includes that the folding line is formed in an arc shape following a forming die finished in an arc shape .
[0007]
【Example】
The details of the sanitary tampon insertion finger sack according to the present invention will be described with reference to the accompanying drawings.
[0008]
1 and 2 are a perspective view of the finger sack 1 and a sectional view taken along line II-II. The finger sack 1 is made of a heat-fusible plastic film 10 such as a thin and flexible polyethylene film, and is detachably joined to the mount 2. The finger sack 1 has a plastic film 10 folded in two along a folding line 3, and the overlapped films are fused together at the joining lines 4 on the left and right side edges. The folding line 3 forms the front edge of the finger sack 1, and on the opposite side thereof, the free edges 6 and 7 of the folded film as the rear edge of the finger sack 1 are located, and the finger insertion opening 5 is located. Is forming. However, these free edges 6 and 7 are easily inserted into the opening 5 by shifting the positions of the free edges 6 and 7 in the front-rear direction so that one of them is close to the folding line 3 and the other is far away.
[0009]
FIG. 3 is a schematic view of a process for continuously manufacturing the finger sack 1. In (A), a polyethylene film 10 having a thickness of 30 microns, which is bent along folding lines 3a and 3b extending in the longitudinal direction on both the left and right sides, is continuously supplied onto the endless mount 2. Next, a fusion wire 4 having a width of 2 mm consisting of a pair of wires 4a and 4b extending in the width direction and parallel to each other is repeatedly applied in the longitudinal direction to the bent and overlapping portion of the film 10 so that the overlapping film 10 is melted. To wear. Thereafter, trimming along the chain line 11 is performed on the outer edge of the fusion line 4 and the central portion in the width direction of the film 10. (B) shows a state in which an unnecessary portion of the trimmed film 10 is removed from the mount 2 and only the finger sack 1 is left. The finger sack 1 is in a state where the fused wire 4 is detachably bonded to the mount 2. In FIG. 3, both side portions of the film 10 are bent so that the pair of left and right finger sacks 1 are opposed to each other on the mount 2, but the film 10 is formed by only one folding line 3 a, for example. You may make it bend. Also, if a small portion 25 of the free edge portion 7 of the finger sack 1 is melted and joined to the mount 2 so as to be peelable, insertion of the finger into the opening 5 becomes easier.
[0010]
FIG. 4 is a schematic diagram of a manufacturing process in a mode different from that in FIG. In (A) of this step, the film 10 is shaped using a plate-shaped mold 20. A finger-like part 22 having a tip end 21 resembling a human fingertip and finished in a circular arc is juxtaposed on the mold 20, and the tip 21 is pressed against the folding line 3 of the film 10 from the inside. At that time, at least the vicinity of the folding line 3 of the film 10 is heated and softened, and / or at least the tip portion 21 of the mold 20 is heated, and the folding line 3 repeats the arc following the mold 20. Mold as you draw. In order to facilitate the forming, an appropriate auxiliary mold for holding the film 10 together with the mold 20 is used if necessary. In the step (B), the released film 10 is supplied onto the mount 2, and the fusion wires 4a and 4b are applied to both sides of the arc-shaped portion, and then trimming of the required shape is performed. In the step (C), an unnecessary portion of the trimmed film 10 is removed and only the finger sack 1 is left on the mount 2. The finger sack 1 produced by this manufacturing process has an arcuate tip edge, so that it is more comfortable to wear than that of FIG. 1 and the tampon can be easily inserted.
[0011]
【The invention's effect】
Since the finger sack according to the present invention is formed by folding the film at the tip edge portion, the portion is smooth and does not irritate the skin. In addition, since the fibrous tampon body and its drawer string are not entangled, the tampon can be easily inserted.
[0012]
The finger sack is releasably joined to the mount via heat-bonding lines that form both side edges along its length, and the tip edge, i.e., the portion located on the folding line, is joined to the mount. Therefore, it becomes a guide for the user to hold the finger sack away from the mount, and the peeling operation becomes very easy.
[0013]
In a mode in which the finger sack is releasably joined to the mount even at the free edge forming the opening, the user can easily insert the finger into the opening.
