Description

[Detailed description of the invention] [Field of industrial application] The present invention is a packaging that can be opened and repackaged quickly and easily by easily fixing the main body wall of the packaging box and the lid plate in close contact with each other. Regarding the lid stopper.

[Prior art] Conventionally, this type of packaging lid stopper was developed in 1983.
There is a structure disclosed in Publication No. 11861.

Figure 3 shows the structure of the lid stopper. 8 is an inner tube, and 9 is an outer tube into which the inner tube 8 is inserted. The outer cylinder 9 has a collar 12 and an L-shaped holding piece 11,
The packaging box 13, in which the main body wall and the lid plate are in close contact with each other, is fixed by sandwiching it from both sides. Here, the outer cylinder 9
The L-shaped holding piece 11 can be bent inside the outer cylinder 9. For this reason, the inner tube 8 is placed inside the outer tube 9.
By inserting the L-shaped holding piece 11, the L-shaped holding piece 11 is pushed outward and is always held in the state shown in the figure so as to be locked to the packaging box 13 side.

Further, an L-shaped groove 10 is provided on the inside of the outer cylinder 9, in which a protrusion 8a on the outer circumference of the inner cylinder 8 is guided. It doesn't come off easily. When opening the packaging box 13, the inner cylinder 8 is pulled out from the outer cylinder 9 as shown in the figure, and the L-shaped clamping piece 11 is removed.

[Problems to be Solved] The above-mentioned conventional lid stopper has a structure in which the inner tube 8 and the outer tube 9 are separated, so the main body wall of the packaging box and the lid plate are tightly fixed before being opened for unpacking. If the inner tube is removed, the outer tube 9 will be left behind on the main body wall and the lid plate and will be separated, which will require time to unpack, and the inner tube and outer tube will not become a pair, resulting in the possibility of loss. The drawbacks were that it was easy to use and lacked reusability.

[Means for solving the problem] The packaging lid stopper of the present invention, which solves the above-mentioned conventional problems, has a bendable clamping piece on the outside that clamps the main body wall of the packaging box and the lid plate from both sides in close contact with each other. Two grooves, an L-shaped groove and a U-shaped groove extending continuously from the groove, are provided on the inner circumferential surface of the cylinder, and the outer circumferential surface of the inner cylinder inserted into the outer cylinder and held in a clamped state by the clamping pieces is provided. , a protrusion that fits into and is guided by the L-shaped groove, and a protrusion that passes through the L-shaped groove and is guided to the U-shaped groove, respectively, and when the inner cylinder is pulled out, either one of the protrusions is partially removed. is configured so that it is caught in the groove.

[Example] Hereinafter, the present invention will be described in detail using drawings showing a preferred example.

1A to 1D show a lid stopper according to an embodiment of the present invention, where 1 is an inner tube and 3 is an outer tube into which the inner tube 1 is inserted. The outer tube 3 generally has a collar portion 7.
and has a bendable L-shaped holding piece 6 at the other end. When the inner tube 1 is inserted into the outer tube 3 in the state shown in FIG. 1, the L-shaped clamping piece 6 is pushed outward and protrudes. , the packaging box 13 in which the main body wall and the lid plate are in close contact with each other is clamped and fixed from both sides.

Now, on the inner peripheral surface of the outer cylinder 3, there is an L-shaped groove 4,
A U-shaped groove 5 extending continuously from the L-shaped groove 4 is provided. Further, on the outer circumferential surface of the inner cylinder 1, a projection 2a guided by the L-shaped groove 4 and a U-shaped groove 5 are provided.
A protrusion 2b guided by is provided. The inner tube 1 is inserted into the outer tube 3 with the protrusion 2a fitted into the L-shaped groove 4 and the protrusion 2b fitted into the U-shaped groove 5, as shown in FIG.

With the above configuration, when the inner tube 1 is inserted into the outer tube 3, the protrusion 2a and the protrusion 2b are caught in the vertical parts of the L-shaped groove 4 and the U-shaped groove 5, respectively, and cannot be easily removed. There is. Next, when pulling out the inner tube 1 as shown in FIG. 2, even if you try to make the protrusion 2a pass through the L-shaped groove 4 as shown in FIG.
When the protrusion 2b is pulled out about half way, the protrusion 2b is in the U-shaped groove 5.
Since the inner cylinder 1 and the outer cylinder 3 are caught on the vertical part of the packaging box 13, they can be removed from the packaging box 13 at the same time without being separated.

[Effect of the invention] As explained above, the invention provides two protrusions on the outer peripheral surface of the inner cylinder, and provides an L-shaped groove and a U-shaped groove in which the two protrusions fit, respectively, on the inner peripheral surface of the outer cylinder. Therefore, when the inner cylinder is combined with the outer cylinder, they will not be separated from each other. Therefore, the inner tube and the outer tube can be removed from the packaging box at the same time, and since the inner tube and the outer tube do not come apart, there is no chance of losing them, making it convenient for reuse.
