Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a packaging case used for packaging articles such as nail files.

[Prior Art] Conventionally, nail files and the like have been packaged by placing a lid on a rectangular box.

Furthermore, a packaging case consisting of an outer case and a push-out inner case is also known.

[Problems that the invention aims to solve] A rectangular box with a lid on top could only be made into a deep packaging case.

In a packaging case consisting of an outer case and a push-out inner case, when the case is carried around, looseness tends to occur between the outer case and the inner case. Further, there was a drawback that the inner case was difficult to fit into the outer case and easy to come off.

[Means for solving problems] This will be explained with reference to the drawings.

The packaging case according to this invention forms a parallelogram-shaped outer box 1 in the shape of an acutely crushed outer case of a pine box, and has right triangular spaces 2 on the left and right sides of the inside of the outer box 1.
Extend one side of the two opposing sides of the bottom plate 5 of the inner box-like inner box 4 of the matte box into the same plane along one of the triangular spaces 2, leaving 3. A wing piece 6 is formed in linear contact with the acute angle corner of the side, and the other side of the two opposing sides of the bottom plate 5 is bent and pressed against the slope 7 of the other triangular space 3 while being tilted. A wing piece 10 is provided which extends upward and has a central portion 8 linearly contacting an upper acute corner, and has tapered portions 9 on both sides of the central portion.

[Function] The inner box is pulled out from the outer box to take out and put the articles in and out, and once that is finished, the inner box is inserted into the outer box again.

Due to the elasticity of the wing pieces 10 when inserted, the inner box 4
never escapes. In particular, the force with which the edge of the tapered portion 9 pushes the slope 7 (the edge of the central portion 8 presses the slope 7
(compared to the force applied to the slope), it becomes wedged into the slope 7, making it extremely difficult to get out.

[Example] A parallelogram-shaped outer box 1 is formed by crushing the outer case of a pine box at an acute angle.

A right triangular space 2 on the left and right inside the outer box 1,
An inner box 4 in the shape of an inner box of a matchbox is provided, except for 3. Then, one side of the two opposing sides of the bottom plate 5 of the inner box 4 is extended in the same plane along one of the triangular spaces 2 to form a wing side 6 that linearly contacts the lower acute corner. is forming.

The other side of the two opposing sides of the bottom plate 5 is bent as shown by the dotted line in FIG.
Its central portion 8 is in linear contact with the upper acute corner. Large arc-shaped tapered portions 9, 9 are formed on both sides of the central portion.

11, 11 are notches provided on the bottom side of the outer box 1,
This is to make it easier to push out the inner box 4.

[Effects of the invention] In the invention, wing pieces are provided on both sides of the bottom plate of the inner box. This makes it easy to insert the inner box. At this time, the tapered portion 9 of the wing piece 10 facilitates insertion.

In addition, since the force exerted by the edge of the tapered portion 9 on the slope 7 is large (compared to the force exerted by the edge of the central portion 8 on the slope 7), it becomes a state in which it bites into the middle of the slope 7. Very difficult to get out of.

Furthermore, the play between the outer box and the inner box comes into contact with the upper edge of the inner box and the lower surface of the ceiling of the outer box due to the restoring force of the wings 10, so that the upper edge of the inner box contacts the lower surface of the ceiling of the outer box. Since it is in contact with the upper edge of the inner box, an appropriate pressing force is applied to the upper edge of the inner box, and it is possible to prevent the inner box from being pulled out.

Claims (1)

[Scope of Claim for Utility Model Registration] A parallelogram-shaped outer box 1 is formed by crushing the outer case of a pine box at an acute angle, and a right triangular space 2 on the left and right inside of the outer box 1,
Extend one side of the two opposite sides of the bottom plate 5 of the inner box-like inner box 4 of the matte box into which it will fit, leaving the inner box 4, leaving 3, to extend in the same plane along one of the triangular spaces 2. A wing piece 6 is formed in linear contact with the acute corner of the side, and the other side of the two opposing sides of the bottom plate 5 is bent to press against the slope 7 of the other triangular space 3 while tilting. A package characterized in that it is provided with a wing piece 10 extending upward, the center part 8 of which touches the upper acute corner in a straight line, and the wings 10 having tapered parts 9 on both sides of the center part.
