Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is capable of pushing and opening a hook member connected to the cylindrical part via a hinge part by inserting a push-opening body of a key body into a cylindrical part of a base body. The present invention relates to a fastener for packaging.

Conventional structures and their problems Some packaging boxes for packaging heavy items are divided into upper and lower halves, such as a lower box and an upper box, to facilitate packaging and unpacking.

By the way, there are packaging fasteners shown in FIGS. 6 to 8 that connect the packaging boxes divided into two in this way.

In FIGS. 6 to 8, reference numeral 1 denotes a base body, which includes a cylindrical portion 2, a flange 3 provided at one end thereof, and a hinge portion 4 provided on the opposing inner wall of the cylindrical portion 2. A pair of L-shaped hook members 5 are provided. Reference numeral 6 denotes a key body that can be inserted into the cylindrical part 2 of the base body 1, and when the key body 6 is inserted into the cylindrical part 2 of the base body 1, the L-shaped hook member 5 is inserted into the hinge part 4. The device is equipped with a push-opening body 7 that is rotated at a . The base body 1 and the key body 6 are connected by a connecting piece 8.

Next, the operation and problems of the conventional packaging fastener constructed as described above will be explained.

By inserting the key body 6 into the cylindrical part 2 of the base body 1, the push-open body 7 of the key body 6 first comes into contact with the hook member 5 in the cylindrical part 2, and when the key body 6 is pushed further, the hook member 5 rotates at the hinge part 4, and as shown in FIG. 8, the hook member 5 and the collar part 3 rotate,
An upper plate 9 and a lower plate 10 made of cardboard or the like are clamped and fixed.

By the way, when inserting the key body 6 into the cylindrical portion 2, the rear end 7a of the push-open body 7 first comes into contact with the hook member 5, as shown in FIG. Then, by continuing to press the key body 6, the push-open body 7 is opened.
gradually comes into contact with the hook member 5 toward the tip. However, since the hook member 5 rotates while rubbing against the end face of a hole formed in a cardboard or the like, contact resistance occurs. In order to push the key body 6 against this resistance, a load corresponding to the pushing force of the key body 6 is applied to the connecting piece 8, centering on the rear end 7a of the push-open body 7, so that it is applied many times. There was a problem in that the connecting portion 8 deteriorated quickly after being used for many years, and sometimes the connecting portion 8 would break.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and provides a packaging material that reduces the load on the connecting parts and reduces the deterioration of the connecting parts even after multiple uses. The purpose is to provide a stop.

Structure of the Invention In order to achieve the above object, the packaging fastener of the present invention has the following features:
When inserting the key body into the cylindrical part of the base body, in order to increase the contact area between the lower part of the push-open body provided on the key body and the hook member, the lower end of the push-open body, the hook member, and the cylindrical part are At least one of the connecting hinge portions is configured to be inclined and parallel to each other.

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

FIG. 1 is a perspective view showing a packaging fastener according to an embodiment of the present invention.

In the figure, reference numeral 11 denotes a base body, in which a flange portion 13 is provided at one end of the cylindrical portion 12, and an L-shaped hook member 15 is provided on the opposing inner surfaces of the cylindrical portion 12 via a hinge portion 14. ing. 15a is a root portion formed on the hinge portion 14 side of the hook member 15. Reference numeral 16 denotes a key body that can be inserted into the cylindrical portion 12 of the base body 11, and has a push-open body 17 having approximately the same width as the cylindrical portion 12. The base body 11 and the key body 16 are connected by a connecting piece 18
are connected by.

The hinge portion 14 on the inner wall of the cylindrical portion 12 is arranged such that the distance from the flange portion 13 decreases from the connecting piece 18 side toward the opposite side, as shown in FIG.
It is installed at an angle.

Further, when the lower end 17a of the push-open body 17 of the key body 16 comes into contact with the hook member 15 when inserted into the cylindrical part 12 of the base body 11, as shown in FIG. They are tilted so that they are parallel to each other. Further, 19 is a finger rest provided on the upper surface 16a of the key body, and 20 and 21 are locking parts for fixing the key body and the base body.

The operation of the packaging stopper of this embodiment configured as described above will be explained.

When the key body 16 is inserted into the cylindrical part, the push-open body 1 of the key body 16 is opened as shown in FIGS. 3 and 4 a.
The lower end portion 17a of 7 abuts against the hook member 15 over a wide range. When further inserted, the hook member 15 rotates from the hinge portion 14, and the locking portions 21 and 20 provided on the base body 11 and the key body 16 are engaged, and the hook member 15 and the collar portion 13 allow the cardboard etc. Clamp and fix the upper plate 22 and lower plate 23 (4th
(see figure b). By the way, since the push-opening body 18 and the hook member 15 are in contact with each other over a wide range during insertion as described above, the reaction force on the connecting portion 18 caused by pushing the key body 16 is greater than that of the conventional one. Therefore, the connecting portion 18 is less likely to deteriorate and can withstand long-term use.

In the embodiment, the hinge part 14 and the push-open body 1
7, the lower end portions 17a of the hinge portions 14 and 7 are both inclined, but only the hinge portion 14 is inclined as shown in FIG.
If it is not necessary, the lower end 17a of the push-open body 17
It is not necessary to tilt the

Effects of the Invention As has become clear from the above explanation, the packaging fastener of the present invention has a cylindrical portion, a flange provided at one end of the cylindrical portion, and a hinge portion on the opposing inner wall of the cylindrical portion. A base body has a pair of hook members connected through a key body, and a key body has a push-open body that can be inserted into a cylindrical part of the base body. When the push-open body and the hook member come into contact with each other during insertion of the push-open body into the cylindrical portion, the lower end of the push-open body and the hinge portion are substantially parallel to each other. Therefore, when the key body is inserted into the cylindrical part of the base body, the lower end of the push-open body comes into contact with the hook member over a wide range, so that the key body is It is possible to reduce the load that the pushing force exerts on the connecting piece that connects the key body and the base body, and as a result, there is little deterioration of the connecting piece, and it is possible to use it many times over a long period of time, making it extremely effective in practice. be.
