Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an opening/closing mechanism for a container such as a compact in which a container main body and a lid body are connected by a hinge, and a hook engagement is not used as a means for closing the container body and lid body. This is the purpose.

BACKGROUND ART Conventionally, in containers such as compacts, hooks (engaging protrusions) are provided at the contact portions of the container main body and the lid, and both hooks are engaged to maintain the closed state of the container.

The above opening/closing mechanism has the following drawbacks.

(1) Strong force is required to disengage the hook when opening the lid, and the hook may be damaged in some cases.

(2) After long-term use, the hook wears out and the closed state becomes uncertain.

(3) Many defective products occur due to variations during container molding, and it is difficult to maintain a constant engagement strength.

(4) In order to obtain sufficient engagement, high dimensional accuracy is required, resulting in high cost.

The present invention eliminates the above-mentioned drawbacks by making it possible to easily open the container body and the lid in one motion without using hook engagement.

Then, the slope (13) of the suppressing piece (11) slides into pressure contact with the slope (37) of the projecting piece (36) of the lid (30),
By pushing the lid (30) upward, the lid (30) is opened (see FIGS. 4 and 6).

Next, a second embodiment of the present invention will be described based on FIGS. 9 to 11. In this embodiment, parts corresponding to those in the first embodiment are indicated by numbers obtained by adding 100 to the reference numbers of the first embodiment.

Each diameter (L) (MXX
)(Y) is the same as in the first embodiment. The feature of the second embodiment is that instead of the spring means (17) shown in the first embodiment, the slope (113) of the pressing piece (111) is
) and the slope (137) of the projection (136),
By pushing the engaging member (110) outward of the container body (101), the large diameter portion (
116) into the notches (1, 32) of the engagement piece (131). That is, when the lid (130) descends, the inclined surface (135) at the lower end of the engaging piece (131) rests on the inclined surface of the large diameter portion (116) of the engaging protrusion (114). (See FIG. 9), by further pushing down the engagement piece (131), the engagement protrusion (114) slides between the inclined surface (135) and the inclined surface of the large diameter portion (116). Large diameter part (116
) moves inward of the container body (101), the small diameter portion (115) moves to the position of the notch (132), and the small diameter portion (115) and the notch (132) fit together. At this time, the slope (137) of the protruding piece (136) and the slope (113) of the pressing piece (111) come into contact (see Fig. 10).
, by further pressing the slope (137) of the projection piece downward, the slope (113), that is, the pressing piece (1
11) is pulled out toward the outside of the container body (1, 01), and the notch (
132). As a result, the engaging piece (131
) and the engaging member (110) are completed, and the lid body (
130) is held in a closed state relative to the container body (101) (see FIG. 11).

The present invention has the above configuration, and the container body and the lid are connected to each other by the difference in diameter between the small diameter part and the large diameter part of the engaging protrusion and the notch formed in the retaining piece of the lid. It can be opened and closed freely.
Since hook engagement is not used, all drawbacks arising from this are eliminated. In other words, it does not require strong force to disengage, preventing damage to the engaging part, and does not require high dimensional accuracy during manufacturing, making it easy to manufacture, reducing the number of defective products, and increasing costs. It prevents it from happening.

Further, as in the above embodiments, the spring means is formed into a plate-shaped screw and the entire engaging member is integrally formed, thereby making manufacturing easier. Further, by providing a slope on the upper end of the suppressing piece and providing a slope on the projecting piece of the lid body opposite to this, the opening operation can be performed more easily.
