Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to an improvement of a sealing device applied to an opening/closing joint, and makes the sealing function safer and more reliable.

[Conventional technology]

For example, in a fiber container consisting of a main body and a lid, a partially cut-out band is applied around the outer periphery of the joint edge, and a fastening piece with a U-shaped cross section is attached to the band so as to be able to rise and fall. The frame is positioned between the upper and lower plates of the fastening piece by falling onto the frame protruding from a part of the band, and then the respective penetrations formed in the corresponding parts of the upper and lower plates and the frame are inserted. A sealing plug that is inserted into a hole to hold the notch of the band in a connected state is published in Utility Model Publication No. 52-128500 and other West German Utility Model Publications No.
Publication No. 7129724 is known.

By the way, as shown in FIG. 5, in the above-mentioned seal, the tips of the engaging claws a, b, c, and d, which are formed in the upper and lower parts of both sides of the lower part of the head in a left-right upwardly extending shape, are connected to the upper engaging claws a, d, respectively. b is located below the side of the lip C provided on the upper plate A of the fastening piece A, and the lower engaging claws c and d are similarly located below the side of the lip E of the lower plate D. Therefore, the lower engaging claws c and d of the seal are exposed to the outside of the lower plate 2 of the fastening piece A.

[Problem that the invention attempts to solve]

By exposing the lower claws c and d of the upper and lower engaging claws to the outside of the fastening piece, the overhanging width of the lower engaging claws can be easily condensed with the fingers. In this condensed state, by moving the plug from side to side and pushing it up,
If something were to happen, the upper engaging pawl would also come out of the through hole, and the sealing function would be inadvertently impaired.

Therefore, in the present invention, when sealing, the above-mentioned upper and lower two stages of engaging claws a to d are connected to the upper and lower side plates of fastening piece A,
The purpose of this is to ensure that the sealing function is ensured by locating the hooks between the two spaces so that the hooking claws are not touched from the outside after sealing.

[Means to solve the problem]

That is, the present invention forms elastic engaging claws whose tips diverge diagonally upward and outward at the upper and lower positions on both the left and right sides of a substantially V-shaped flat plate with a head at one end. Each of the hooking claws on the plug body is inserted into the respective through-holes in the frame metal interposed between the fastening piece having a U-shaped cross section and the upper and lower side plates of this fastening piece to connect these fastening pieces and the frame metal. The structure is characterized by a sealing device in which the tips of each of the engaging claws are located between the upper and lower plates of the fastening piece, and each is formed in a width that extends outside the width of the through hole located above.

[Effect]

The sealing device according to the present invention positions the frame metal between the upper and lower side plates of the fastening piece, and then inserts the frame metal with its head left in the upper and lower through-holes formed in a communicating manner at corresponding locations between the upper and lower side plates and the frame metal. When inserted, the upper, lower, left and right engaging claws condense in the width direction as they pass through the through holes, and after passing through each hole, the left and right claws expand due to their elastic restoring force, so that the upper and lower engaging claws respectively It is located between the upper plate and the lower plate of the fastening plate, and the fastening piece and the internal frame can be maintained in a connected state unless the stopper is damaged by breaking the head, etc. be. In addition, the upper engaging claw may have its tip widened to the left and right at the lower position of the frame, and the lower engaging claw may be widened so that both sides thereof are in contact with the mouth edge of the through hole. , it is possible to eliminate the wobbling of the stopper.

〔Example〕

Next, the present invention will be explained with reference to the embodiment shown in the figure.
In Figs. 1 to 3, reference numeral 1 denotes a stopper, and the stopper has a head 2 formed at the upper end of a flat plate 1' made of synthetic resin that is approximately V-shaped when viewed from the front, and has a head 2 on the upper and lower sides of both left and right sides. By providing notches 3, 3 facing diagonally downward and inward at each position of the second stage, it is inclined diagonally upward and outward, and the dimension l between the upper and lower tips 4' and 5' is defined as the dimension L described later. Engaging claws 4a, 44a', 4b, 4 are made smaller and can be bent inward, respectively.
b', 5a and 5b are formed. Of the above-mentioned engaging claws, the upper ones have 4a and 4 on the left and right respectively.
Although two lashes 4b and 4b' are shown for each lash a', it is also possible to have one each for the left and right lashes. Further, the tips of the upper and lower engaging claws may be bent in opposite directions when viewed from the side.

Reference numeral 11 denotes a partially cut-out fastening band that is wound around the outer circumference of the opening of the container 12, and has a U-shaped cross section at one end of the cutout, and has upper and lower side plates 13a, 13.
The base of a fastening piece 13 formed with an internal dimension L larger than the above-mentioned dimension l is pivotally attached, and the intermediate part of the fastening piece and the other end of the band are connected by a link piece 14. This fastening piece 13
When it is laid down so that it can be superimposed on the band 11 on the pivot side, the other end of the band is tightened via the link piece 14 in a direction that reduces the distance between the notches. 15 indicates the upper and lower side plates 1 of the fastening piece 13 when the fastening piece 13 is laid down.
3a and 13b, respectively, with a U-shaped frame in plan view, which is fixed to the outer surface of the band 11 so that it can be interposed with a slight space S, S' vertically. The frame is provided with vertically communicating lines when the fastening piece 13 is folded down, and the width is smaller than the width of the head 2, and the engaging claws 4a, 4b and 5a, 5b are condensed in the width direction. Through holes 13'a, 1 through which the state can pass through
5' and 13'b are formed, respectively.

In the above configuration, first the band 11 is applied to a predetermined location of the container 12 as shown in the third figure, and then the fastening piece 13 is folded down so as to fit along the side of the band 12, and the notched ends of the band are drawn together. At the same time, the upper and lower side plates 13a, 13 of the fastening piece 13
A frame metal 15 is interposed between b. Therefore, when the plug body 1 is inserted into the respective through holes 13'a, 15', and 13'b formed in the upper and lower side plates and the frame metal, the lower engaging claws 5a and 5b condense in the width direction and penetrate through the holes. By passing through the holes 13'a, 15' and passing through the through hole 13'a with the upper engaging claws 4a, 4b similarly condensed in the width direction, the tips 4', 5' of each claw are fastened. Upper and lower side plates 13 in piece 13
When located in the spaces S and S' between a and 13b and the frame metal 15, the elastic restoring force expands the width to the left and right to be larger than the respective widths of the through holes 13'a and 15' located at the top, respectively. That's what I do. Therefore, after the plug 1 is inserted, it cannot be removed from the insertion portion unless the plug is damaged, thereby achieving the purpose of sealing.

In the above, the frame metal 15 has a single through hole 15', but as shown in FIG. In this case, the upper engaging claws 4a, 4b are connected to the upper frame 2.
5a, and in any case, each tip 4' of each upper and lower engaging claw,
5' is located between the upper and lower side plates 13a and 13b of the fastening piece 13.

In addition, if at least the lower engaging claws 5a and 5b of the plug 1 are made so that they can come into contact with the mouth edge of the through hole 13'b when widening, the left and right wobbling of the plug 1 after insertion can be prevented. It can be eliminated.

〔effect〕

As described above, according to the present invention, when the plug is inserted into the required through hole, the tips of the upper and lower engaging claws on both sides are located between the upper and lower side plates of the fastening piece, so that the lower engaging Unlike the conventional method in which the nails are exposed outside the fastening piece, by pinching the left and right nails with your fingers and condensing their widths, you can eliminate the negative effects of being pulled out and make the seal safe and secure. It is played.
