The present invention relates to a fastener in which a socket having an insertion hole and an insertion head to be inserted through the above-described insertion hole and a socket which is inserted on one side and a filament having the insertion head which is inserted on the other side are integrally formed of a synthetic resin. will be.

Fasteners of this kind are widely used for attaching tags or labels to products, for tying slippers, sandals, etc. together, for sealing bags for bags or for machine covers.

1 and 2 are plan and side views of a conventional fastener of this kind. The fastener 1 consists of a filament 3 having a socket 2 formed as an insertion hole at one end and an insertion head 4 at the other end, and these constituent members are formed in a straight line as a synthetic resin.

In general, the filament 3 is stretched to form a long length and a small diameter after forming. The conventional paste of the above structure is used through the following process. As shown in FIG. 3, the fastener 1 is passed through the hole of the tag P so that the tag P is caught by the filament 3, and then the socket 2 and the insertion head 4 are held with both fingers. The insertion head 4 is inserted into the insertion hole of the socket 2 to form a closed curved ring while preventing the insertion head from being pulled out of the socket by the engagement piece 18 of the insertion head 4.

The manual work of connecting the socket and the insertion head of a conventional fastener takes a lot of time when attaching a price tag and a classification tag to a large amount of goods. In particular, in the fastener of the long length of the filament (3), it was not easy to find and pick up the socket and the insertion head, the coupling operation was inefficient. In order to improve the efficiency of the joining job, attempts were made to combine the socket and the insert using a machine, but it was difficult to develop such a joining device for the following reasons.

That is, because the socket and the insertion head are separated by a long filament, and the resilience of the filament tends to return them to the separated position easily when the socket and the insertion head are brought close to each other.

In addition, because fasteners are used to bind two or more articles together in addition to tagging, the filaments need to be formed longer in length and smaller in diameter than plastic to produce plasticity. However, there are some limits to the length and diameter of the filament. This is because the high tackiness of the molten resin picks up the molten resin into the mold and does not easily flow into the long mold. Therefore, conventionally, the filament is formed into a mold with a diameter larger than a predetermined size and short in length, and then pulled to form a long thin filament. However, there is a limit to the stretching of these filaments.

Therefore, to form fasteners with long filaments, the length of the mold must be inevitably long and the injection pressure of the molten resin must be increased. In order to overcome the above-mentioned drawbacks of the conventional fasteners, an object of the present invention is to provide a fastener capable of easily coupling an electric socket and an insertion head using a coupling device.

It is a second object of the present invention to provide a fastener composed of filaments formed to a sufficient length by molding without the need for stretching operations after molding. In particular, the second object is to provide a fastener composed of a filament that is at least twice as long as the filament length of a conventional fastener without tensioning.

A third object of the present invention is to provide a fastener that can reduce the length of the mold and reduce the injection pressure even when forming a fastener of approximately the same length as a conventional fastener, thereby reducing the size and energy consumption of the fastener forming apparatus. .

It is a fourth object of the present invention to provide a fastener capable of halving the travel distance or stroke of a stretching machine when stretching a filament.

A fifth object of the present invention is to provide a fastener set that can efficiently carry out the task of attaching a price tag and a classification tag to a commodity because they are not scattered and not intertwined when transported in a carton.

A sixth object of the present invention is to provide a fastener in which the tag is secured to a portion of the filament so that the tag does not slip along the filament so that the tag can be securely attached to the fastener before the fastener is supplied to the article. A seventh object of the present invention is to provide a fastener formed so that it is not manual when attaching the tag to the fastener and can attach a large amount of the tag to the fastener at one time.

The purpose of the first to the fourth is the filament is formed integrally with thermoplastic synthetic resin, the filament is inserted into the socket and the end is inserted into the socket and the other end is inserted into the socket is formed, the other end, the filament This is achieved by fasteners, which are bent at and formed with weak connecting members so that these parts can be easily separated between the outer end of the socket and the outer end of the insertion head or between the insertion head and the filament part near the socket. The above first to fifth objects are achieved by fasteners connected and engaged such that the filaments extending from the socket and the filament extending from the insertion head can be easily separated, either directly or by protrusions provided on these filament parts. .

A sixth object of the present invention is achieved by a tag length installed fastener located at the curved middle portion of the filament.

The seventh object of the present invention is to retain the tag length located in the bent middle part of the filament and to be attached to the connecting rod by the socket and the insertion head or the weakly connected tag length, and the spacing between adjacent tag hangers is between the holes of the tag. Achieved by fasteners set equal to the spacing. Hereinafter, the present invention will be described with reference to the accompanying drawings. 4 and 5 are a plan view and a side view of a first embodiment of a fastener according to the invention, wherein the fastener 1 comprises a socket 2 and a filament 3, a filament extending from one of the sockets 2; It consists of the insertion head 4 formed in the front-end part of (3).

These structural members are integrally formed of thermoplastic synthetic resin such as nylon, polypropylene, polyethylene, polyester, or the like. The socket 2 is formed in a cylindrical shape, and the cylindrical body 5 is formed with an insertion hole 7 surrounded by a round wall 6 and through which the insertion head 4 penetrates. The annular engagement teeth 8 are formed in the center of the insertion hole 7 of the socket 2 so that the insertion head 4 may not come out of the socket.

In this example, the engagement value 8 is formed around the entire interior of the round wall 6, but may be formed only on a part of the inner circumference. In detail, the engagement value 8 is comprised by the annular projection 9 concentric with the socket 2, and the connection part 10 which connects the annular projection and the round wall 6 which were electrical.

The connecting portion 10 is formed of the mating surfaces 11a and 11b on each side so that the insertion head 4 can engage the one of the mating surfaces 11a and 11b in the socket 2. It becomes insertable.

Reference numeral 12 denotes a guide surface of the annular projection 9, and reference numeral 13 denotes a sliding surface that is inclined at about 10 degrees or more with respect to the axis of the socket 2. The slide surface 13 may be provided at an angle of 10 degrees or less or parallel to the axis of the socket 2.

The filament 37 forms a loop when the insertion head 4 at one end of the filament is inserted into the insertion hole 7 of the socket 2 at the other end to bind a pair of articles or to be hooked on the hook. The tag will be attached to the article. In the present invention, the filament 3 is bent in the middle and the filament portion 14 extending from the socket 2 and the filament 15 extending from the insertion head 14 are substantially parallel and their ends are intermediate expansion. It is coupled by the unit 16. In the first embodiment, the center line A of the filament portion 15 passes through the axis 0 of the socket 2 and the outer end of the insertion head 4 is connected to the outer end of the socket 2 so that the filament ( 3) will look like a J-shape.

The connection between the insertion head 4 and the socket 2 can be easily broken to separate them.

The filament portions 14 and 15 can be enhanced in strength and flexibility by stretching after casting.

This drawing may be done immediately after the filament is formed, or with the given drawing device. The insertion head 4 fitted into the insertion hole 7 holds the head 17 slightly smaller than the diameter of the annular projection 9 of the socket 2 at the front end of the insertion head 4, and the electric head 17 ) Makes it easy to fit into the insertion hole (7) by forming a bullet, and the front end of the head (17) is connected to one side of the socket (2) via the first connecting member (24), and the first The connection member 24 is a member for supporting the insertion head 4 attached to the socket 2, and the first connection member 24 is broken so that the insertion head 4 is inserted into the socket 2. The fasteners 1 form an endless loop until they are inserted into the two ends, and these two insertion heads 4 are twisted in the sockets 2 fixed so as to be immovable just before they are inserted into the insertion holes 7. It can be easily separated from 2).

As shown in Figs. 4 and 5, the first connecting member 24 is substantially conical, and the diameter of the connecting portion 24a integrally with the socket 2 is smaller than that of any part of the fastener 1. The fact that the fastener 1 forms an endless loop through the first connecting member 24 until the insertion head 4 is separated from the socket 2 is formed in a diameter. It is to make it easy.

In addition, the first connection member 24 may be formed in any form to attach and hold the insertion head 4 to the socket 2 until the fastener 1 is used. For example, the connecting members may have a cylindrical shape with slightly recessed portions of the connecting portion 24b to facilitate separation from the socket 2 to which the first connecting member 24 is fixed, as shown in FIGS. 6 and 7. have. The second, third and fourth connection members described later also function in the same manner as the first connection member 24.

Engage with (11) or (11b) to prevent the insertion head 4 from escaping from the socket 2.

From the side of FIG. 4, the junction part 24a is thinly bonded at the rear end of the head 17, and becomes thicker toward the opposite side, and is formed in the conical shape.

In addition, the pair of engaging pieces 18 having some elasticity is extended at an angle to the rear of the insertion head 4 when not engaged with the socket 2 (FIG. 4). Although the number of pieces 18 is not limited to two, using two engagement pieces 18 is because it is easy to remove the completed fastener 1 from a mold.

And the connecting member 18 of the pair of engaging pieces 18 can be located in the position other than the back of the head 17, the head 17.

On the rear of the rear end of the head 17, the first connecting rod 19 and the fuselage 20 are formed in order, and in fact, a ball stopper 21 is formed in order. The fuselage 20 is cylindrical and its diameter is Smaller than the annular projection 9, the stopper 21 restricts the movement distance that the insertion head 4 moves over the engagement value 8, and at the same time, performs a swing performed when the insertion head 4 is inserted into the insertion hole 7; It is preferable to minimize the diameter of the stopper 21 to be somewhat larger than the diameter of the head 17. However, if the insertion head 4 moving above the engagement value 8 cannot be restricted, the stopper 21 is not limited. There is no need to install), and it can be in any form.

A second connecting rod 22 is formed on the left side of the stopper 21 facing the filament 15, and a handle portion 23 is formed at an economic point between the second connecting rod 22 and the filament portion 15. In this handle part 23, it is possible to hold the fastener 1 by hand when inserting the insertion head 4, and it is not necessary to install the handle part 23 and can be installed in any form. It can also form smaller diameter than (21). Hereinafter, the socket 2 and the insertion head 4 shown in FIGS. 4 and 5 will be described.
