Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lid engagement structure that allows the upper lid to be easily and stylishly attached to the lower lid in a resin compact container.

Prior Art Most conventional compact containers have a structure in which the top lid is mounted on a pivot that passes through the bottom lid from one end to the other, which makes installing the top lid complicated and laborious. Both ends of the pivot shaft are visible from the outside, which is not aesthetically pleasing.

Problems to be solved by the invention This invention makes it possible to easily assemble the upper cover into the lower cover by skillfully utilizing the slight flexibility of the resin, and also improves the appearance by preventing the support shaft of the upper cover from being exposed to the outside. The present invention aims to provide a lid engagement structure that allows a product with good appearance to be obtained.

Means for solving the problem The present proposal was devised based on the above objectives.
In the structure in which the upper cover is attached to the lower cover so as to be freely openable and closable, a concave-shaped notch is provided at the center of one side edge of the lower cover, and a downward projecting edge corresponding to the notch recess is provided at the center of one side edge of the upper cover. and inserting the projecting edge into the notch recess, inserting pins projecting from both sides of the projecting edge into recesses formed in both side walls of the notch recess, and inserting the projecting edge into the recess. A slight gap is interposed around the outer periphery of the pin in the hole, an engagement recess having an arbitrary width is cut out on the surface of the pin, and a stopper is provided in the engagement recess, which protrudes from the inner wall surface of the engagement recess. The gist of this is a configuration that allows them to be engaged with each other.

Embodiment The details of the present invention will be explained below with reference to the embodiment shown in the drawings. 1 is a lower lid, 2 is an upper lid, 3 is a concave notch formed in the center of one side edge of the lower lid 1, and 4 is the upper lid 2. A projecting edge portion having approximately the same width as the notch recess 3 bored in the center of one side edge;
is inserted into the notch recess 3 of the lower lid 1.

A cylindrical recess 9 is formed in both side walls 3' of the notch recess 3, and a stopper 1 is installed at one end of the recess 9.
0 is bored, and cylindrical pins 11 corresponding to the recessed holes 9 are protruded from both ends of the projecting edge 4 of the upper lid 2, and the pins 11 are rotatably engaged with the recessed holes 9. The stopper 10 is then engaged with an engagement recess 12 cut out over approximately 1/4 of the circumferential surface of the pin 11. The diameter of the pin 11 is slightly smaller than that of the recessed hole 9, and the pin 11 is set so that a slight gap 13 exists around the outer periphery of the pin 11 within the recessed hole 9.

Function In the embodiment, the engagement recess 12 is cut out over approximately 1/4 of the circumferential surface of the cylindrical pin 11, and the stopper 10 is engaged with this recess 12, so that the space of the engagement recess 12 is Within the width, the top cover 2 can only be in a half-open state, and when the top cover 2 is rotated more forcefully in the opening direction from this half-open state, the stopper 10 overcomes the engagement recess 12 and comes into contact with the surface of the pin 11, and the top cover opens. When the stopper 10 is on the surface of the pin 11, the upper lid 2 can be rotated firmly and the upper lid 2 can be opened at a free opening angle, and the upper lid 2 can be kept in the open upright state.

Effects of the invention As described above, the present invention forms a square-shaped notch recess at the center of one side edge of the lower lid, and a projecting edge corresponding to the notch recess at the center of one side edge of the upper lid. The edge is inserted into the notched recess, and pins bored on both sides of the protruding edge are rotatably inserted into the holes bored in both side walls of the notched recess, and the pins are exposed outside the container. A container with good appearance is obtained without the risk of
Also, when assembling the top cover, one pin is first engaged with the recessed hole, and then the protrusion of the other side is inserted into the other recessed hole by forcefully inserting the protrusion into the notched recess, and the notched recess is filled with resin. Depending on the flexibility of the characteristics, the opening will be slightly adjusted, and as the protrusion fits in, the protrusion will completely engage the recessed hole, making assembly much easier than conventional products, and furthermore, the top cover 2 will be opened in the opening direction. When the top cover 2 is rotated, the stopper 10 passes over the engagement recess 12 and comes into strong contact with the outer periphery of the pin 11, and the rotation of the top cover 2 becomes rigid, and the top cover 2 is maintained in the open and upright state at a free opening angle. It has the following effects.
