Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a compact container for storing cosmetics, etc., and in particular, the unlocking operation part for opening the lid is located on the hinge part on the rear edge of the container. This invention relates to an improvement in a so-called bucket-type compact container.

[Prior Art] Basically, a compact container has a container main body and a lid connected to each other by a hinge part on the rear edge side so as to be openable and closable, and the lid body is locked in the closed state by a locking part on the front edge side. It is structured so that it can be stopped.

There are various structures for the locking part, but many compact containers have an operation piece for releasing the lock directly on the locking part, so there is no part that you operate with your finger when opening the lid. is usually located at the front edge of the container.

If the unlocking operation part is on the front edge side of the container,
The degree of freedom in designing the front part, which is most important for aesthetics, is greatly restricted. Furthermore, as shown in Fig. 5, considering the normal usage condition in which the compact container is placed on the palm with the front edge side F facing you and the rear edge side B (hinge side) facing your fingertips, it is assumed that the rear edge side B It is easier to operate if the lid opens as shown by arrow b when the operating part is pushed in the direction of arrow a. From this point of view, a so-called bucket-type compact container was developed.

A typical conventional bucket-type compact container has a structure disclosed in Japanese Utility Model Application Publication No. 59-90710.

A push button for releasing the lock is provided on the rear edge of the container, and a slide plate is attached to the container body to release the lock of the lid by transmitting the operating force applied to the push button to the locking part on the front edge side. It is installed inside.

<<Problems to be Solved by the Invention>> However, the above-mentioned conventional bucket-type compact container has a large number of parts, making the structure and assembly complicated, resulting in high costs. Furthermore, since a sliding plate extending from the front to the rear is provided within the container body, the degree of freedom in the internal structure of the container is significantly restricted, which tends to lead to an increase in the thickness of the container. If the slide plate is made extremely thin in order to minimize the increase in the thickness of the container, malfunctions are likely to occur due to bending or bending of the slide plate.

This idea was devised in view of the conventional problems mentioned above, and its purpose was to have a structure that was as simple and robust as possible, and which had less impact on other parts of the design to ensure smooth operation. An object of the present invention is to provide a bucket-type compact container which is adapted to be used as a container.

《Means for solving the problem》 Therefore, in this invention, the hinge piece that supports the lid so that it can be opened and closed is made into a separate part from the container body, and this hinge piece is placed in a position parallel to and below the hinge axis of the lid. It is coupled to the container body via a second hinge shaft. The lid body is configured to move in the front-rear direction by swinging the hinge piece about the second hinge axis. Further, a spring member is built in to always bias the lid body backward. on the other hand,
The locking portion has a structure that allows the lid to move back and forth, and is configured to unlock the lid when moved forward and to lock the lid when moved rearward.

《Operation》 Press the rear edge of the lid forward with your fingertips.
The hinge piece swings forward about the second hinge axis, and the lid moves forward. When the lid slides forward, the locking state at the locking portion is released and the lid can be opened. When you release your finger from the rear edge of the lid, the hinge piece swings backward by the spring member and returns to its original position. When you close the lid in this state, the locking portion closes the lid. held in state.

<<Example>> Figs. 1 to 4 show the structure of a compact container according to an embodiment of the present invention, and Fig. 5 shows its usage mode.

In the figure, 10 is the container body, 12 is the inner plate, 1
4 indicates a lid body. A groove 16 is formed on the side surface of the inner plate 12, and a protrusion 18 is formed on the inner surface of the container body 10 in correspondence with the groove 16.
8, the inner plate 12 is integrally assembled with the container body 10. The inner plate 12 combined with the container body 10 is considered to be a part of the container body, and in the following description, both the container body 10 and the inner plate 12 may be referred to as the container body 10. As will be explained below, the container body 10 and the lid 14 are connected to each other at a hinge portion on the rear edge side B so as to be freely openable and closable.
The lid body 14 is fixed to the container body 10 in a closed state by the locking portion.

A notch 20 is formed in the rear wall of the container body 10,
Correspondingly, a notch 22 is formed at the rear of the inner plate 12, and a hinge space 26 for accommodating a hinge piece 24 is formed between the notches 20 and 22. The hinge piece 24 has a pair of bearing parts 2
It is a roughly U-shaped component with 8 and 28 erected, and hinge shafts 30 and 30 are integrally formed to protrude from both sides of the lower part. This hinge shaft 30 is the aforementioned second hinge shaft.

Before assembling the inner plate 12 to the container body 10, insert the hinge piece 24 into the hinge space 26 of the container body 10.
The hinge shafts 30, 30 are connected to the container body 1.
0 half-split shaft holes 50, 50. After that, when the inner plate 12 is assembled with the container body 10, the inner plate 12
The half shaft holes 52, 52 press the upper half of the hinge shafts 30, 30. As a result, the hinge piece 24 is capable of swinging movement in the front-rear direction by a predetermined angle about the second hinge shaft 30.

Further, the lower end of a leaf spring 32, which acts as described later, is inserted into a gap between a spring receiver 54 erected on the rear inner surface of the container body 10 and the rear wall of the inner plate 12.

A mirror 36 is attached to the inner surface of the lid 14, and a bearing 38 is integrally formed in the center of the lower surface of the rear end of the lid 14, and a bearing part 38 is integrally formed in the center of the lower surface of the front end. A hook piece 40 is integrally formed. The bearing portion 38 of the lid body 14 is fitted between the pair of bearing portions 28, 28 of the hinge piece 24, and the hinge shaft 42 is attached passing through these bearing portions 28 and 38. The lid body 14 is now hinged to the hinge piece 24,
The lid body 14 can be opened and closed about the hinge shaft 42. The hinge shaft 42 of the lid body 14 is parallel to and located above the hinge shaft 30 of the hinge piece 24, and when the hinge piece 24 swings back and forth around the hinge shaft 30, the lid body 14 is designed to move forward and backward.

Further, the upper end side of the leaf spring 32, which is curved into a roughly C-shape, acts on the root corner of the bearing portion 38 of the lid body 14, and always urges the lid body 14 backward. The lid body 14 is attached to the hinge shaft 4
2 is also biased in the opening direction.

A locking hole 44 corresponding to the hook piece 40 of the lid body 14 is formed in the center of the front horizontal surface of the inner plate 12. The hook piece 40 has a hook part 46 that bends inward, and when the lid body 14 is closed, the hook piece 40 penetrates into the locking hole 44, and the hook part 46 fits into the inner edge of the locking hole 44. It hooks and locks the lid body 14 in this state. The lower surface side of the hook portion 46 is a chamfered slope, and the corresponding upper surface edge of the locking hole 44 is also chamfered to facilitate entry of the hook piece 40.

FIG. 2 shows a state in which the lid 14 is locked with the container body 10 closed. In this state,
The lid body 14 is pulled rearward by the force of the leaf spring 32, and as a result, the hook piece 40 is caught on the inner edge of the locking hole 44.

From the above state, when the rear edge or back surface of the lid body 14 is pressed forward (arrow a) with a finger as shown in FIG. The lid body 1 swings forward.
4 moves forward. Then, the hook piece 40 is displaced forward within the locking hole 44, and the hook portion 46 is inserted into the locking hole 4.
4, and the locked state is released.
At this time, the spring force of the leaf spring 32 becomes more strongly biased toward the opening direction of the lid 14, and as shown in FIG. 4, the lid 14 rotates in the direction of arrow b and opens.

Further, when the opened lid 14 is pressed and closed, the lid 14 is pulled forward somewhat by the action of the slope of the hook portion 46 of the hook piece 40 and the slope of the locking piece 44, and the hook piece 40 is engaged. It enters the stop hole 44 and becomes the locked state shown in FIG.

In this embodiment, one leaf spring 32 has both the function of biasing the lid body 14 backward and the function of biasing the lid body 14 in the opening direction, which reduces the number of parts and simplifies the configuration. It has the effect of making
However, the present invention is not limited to this, and each biasing action may be performed by a separate spring member, or the lid body 14
There is no need to provide a means for biasing in the opening direction.

<<Effects of the invention>> As explained in detail above, in the bucket-type compact container according to this invention, there is no sliding plate extending from the front to the rear inside the container body, and the hinge part on the rear edge side of the container is not provided. Only the structure for releasing the lock is small, and the locking portion on the front edge side does not require any large movable part for releasing the lock.Therefore, the structure is very simple and assembly is easy. In addition, there is little influence on the design of other parts, and in particular, the degree of freedom in the structure within the container body is not impaired. Furthermore, since the lock is released by moving the robust lid itself back and forth, there are fewer failures and stable operation is achieved.
