The configuration includes a second engagement means for

Effect With the above structure, when the packaging fastener of the present invention inserts the key body into the base body, the base body and the key body are first temporarily fastened by the first engaging means, and then the main packaging fastener is temporarily fastened to the key body by the first engaging means. The work when attaching the tool to a cardboard or the like can be facilitated.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

FIG. 1 is a perspective view of a packaging fastener according to an embodiment of the present invention. In the figure, reference numeral 14 is a base body, and a flange 16 is provided at one end of the cylindrical portion 15. An L-shaped hook member 18 is provided on the facing inner surface via a hinge portion 17. Further, 19 is a cylindrical portion 15 of the base body 14.
It has a push-open body 20 which is a key body that can be inserted into the cylindrical part 15 and has a width that is approximately the same as the width inside the cylindrical part 15. The base body 14 and the key body 19 are connected to a connecting piece 22 via a hinge part 21.
are connected by Further, an intermediate locking protrusion 23 is provided on the inner wall of the cylindrical portion 14, and a fitting protrusion 24 is provided on the outer wall of the push-opening body 20. The flange 16 is provided with a recess 26 in which the flange 25 of the key body and the connecting piece 22 are accommodated when the key body 19 is inserted into the base body 14.

The key body 19 has an opening 27 into which a finger can be inserted, and at the back of this opening there is an inclined plate 2 that guides the inserted finger.
8 is provided. Further, as shown in FIG. 3, the distance between the hinge portion 17 provided on the inner wall of the cylindrical portion 91S15 and the flange portion 16 decreases from the side where the connecting piece 22 is formed toward the opposite side. Further, the outer wall of the cylindrical part 15 is provided with ribs to prevent it from falling off easily when the cylindrical part 15 is inserted into a hole bored in a cardboard or the like. A plurality of 29 are provided.

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

As shown in FIGS. 3(a) to 3(c), the key body 19 is folded back and rotated from the hinge part 21 to the base body 14 side, and the cylindrical part 1
5, the fitting protrusion 24 provided on the opening body 20 is pushed onto the intermediate locking protrusion 23 provided on the inner wall of the cylindrical portion 15.
comes into contact. In this state, when the key body 19 is pushed into the cylindrical portion 15 more forcefully, the periphery of the fitting protrusion 24 of the push-opening body 20 and the periphery of the intermediate locking protrusion 23 are elastically deformed, and the fitting protrusion 24 rides on the intermediate protrusion 23. Also, in this state, the rear end 20a of the push-opening body 20 contacts the hook member 18 provided on the inner wall of the cylindrical portion 14 via the hinge portion 17, so that the cylindrical portion 1 is temporarily closed.
The advancement of the key body 19 into the interior of the key body 5 is obstructed, and as shown in FIG.
), one key body is in a temporarily locked state inside the cylindrical portion 15, that is, an intermediate locked state. That is, in this state, the rear end 20a of the push-opening body 20 of the key body 19 is in contact with the hook member 18, and the fitting protrusion 24 is in a state where it has climbed over the intermediate locking protrusion 23. As shown in FIG. 3(b), unless a new load is applied to the key body 19, that is, a load pushing the key body 19 more forcefully into the cylindrical part 15, or a force pulling it out from the inside of the cylindrical part 15 in an outward direction. The locked state continues.

Next, in this state, when the key body 19 is pushed further into the cylindrical part 15, the hook member 18 is pushed by the push-open body 20, and therefore the hook member 18 is pushed into the hinge part 1.
7, the key body 19 completely enters inside the cylindrical portion 15 as shown in FIG. 3(c). On this occasion,
The fitting protrusion 24 advances while coming into contact with the hook member and causing elastic deformation around the fitting protrusion 24. After the hook member 18 has been completely rotated by the push-opening body 20, the fitting convex portion 24 engages with the lower end of the hook member 18, and the fixation of the key area 19 to the base body 14 is completed. At this time, since the flange 25 is provided around the upper surface of the key body, the flange 25 closes around the opening of the cylindrical part 15 of the base body 14 as soon as the insertion of one key body into the cylindrical part is completed. In doing so, it is possible to reliably prevent overcrowding.

Further, the cylindrical portion 15 includes the flange portion 25 and the connecting piece 22.
Since the four portions 26 are stepped by the thickness of the key body 14, the upper surfaces of the key body 19 and the base body 14 are flush with each other when the key body 19 is fixed to the base body 14.

Next, changes in the state of the main parts when the present packaging stopper is attached to the corrugated poles 30, 31, etc. are described using FIGS. 4(a) to 4(c).

First, the base body 14 is inserted into the through hole bored in the cardboard 30.31, and the key body 19 is rotated and inserted into the cylindrical part 15 in the same manner as described above, as shown in FIG. 4(a). The fitting convex portion 24 comes into contact with the intermediate intervening convex strip 23 . In this state, when the key body 19 is further pushed into the cylindrical portion 15, the fitting convex portion 24 crosses over the intermediate locking convex strip 23, resulting in a state as shown in FIG. 4(b). In this state, when the key body 19 is pushed further, the hook member 1
8 rotates, the fitting convex portion 24 passes through contact with the hook member 18, and is latched to the lower end of the hook member 18, completing fixation. The cardboard 31.31 is then held between the collar 16 and the hook member 18.

By the way, as described above, the hinge portion 17 is shaped like the flange portion 16 as it goes from the side where the connecting piece 22 is formed to the opposite side.
Since the key body 19 is inclined so that the distance between the key body 19 and the key body 19 is small, the resistance when inserting the key body 19 into the base body 14 is alleviated, and the load on the connecting piece 22 can be reduced compared to the conventional type. Therefore, when the packaging stopper is used repeatedly, the load on the connecting piece 22 is reduced, and the occurrence of breakage, elongation, etc. at the rehinge portion is reduced.

Further, the unfitting operation between the base body 14 and the key body 19 is performed by inserting a finger into the opening 27 on the top surface of the key body 19, and hooking the finger onto the end portion 19a of the key body 19 while being guided by the inclined plate 28. This is done by pulling it upwards.

By the way, the effects of the packaging fastener of this example are as follows.

That is, as mentioned above, the packaging fastener of this embodiment is in a state (with the key body 19 inserted into the cylindrical part 15 of the base body 14 and the fitting convex part 24 riding over the intermediate protrusion 23). (See Figure 3(b)), so you can temporarily lock the main packaging fastener in advance, and by doing so, you can attach it to cardboard etc. with one hand. This can be done easily.

In addition, as described above, since a plurality of ribs 29 are formed on the outer periphery of the cylindrical portion 15, the main packaging stopper can be easily removed after being inserted into a through hole of a cardboard or the like. This makes the above-mentioned installation work even easier.

Furthermore, since the key body 19 and the base body 14 are connected by connecting pieces at their ends, the key body 19 is connected to the base body 1.
4, the final stopper is attached to the step pole etc. and the state shown in FIG. While transporting the cardboard with the key attached, move it along the narrow path and gradually trace the top surface of the key body 19 starting from the connecting piece.
It is also possible to automate subsequent processes such as pushing the push-open body into the cylindrical part.

Effects of the Invention As has become clear from the above explanation, the packaging fastener of the present invention includes 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 having a pair of hook members connected via a key body having a push-opening body that can be inserted into a cylindrical portion of the base body; and insertion of the push-opening body into the cylindrical portion. In this case, a first engaging means for fixing the key body and the base body in a first insertion process until the push-opening body and the hook member come into contact with each other, and the hook a second insertion assumption for defining the key body and the base body in a state in which the hook member has completed rotation after a second insertion assumption in which the member and the push-open body are in contact with each other; Since it is equipped with an engaging means, when inserting the key body into the base body, the base body and the key body are first temporarily fastened by the first engaging means, and the main packaging fastener is It has excellent effects such as being able to facilitate the work of attaching it to cardboard boxes, etc., and is practically effective.
