Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing mechanism for a container, and more particularly to an opening/closing mechanism for a container whose container has a double structure, upper and lower.

Conventionally, the above-mentioned containers include a lid, an upper container,
2. Description of the Related Art A compact cosmetic container is known in which the lower container is hinged at three parts and provided with locking means such as engaging protrusions on the respective peripheries. The purpose of this is to store the cosmetic in the upper container and to store the puff separately from the cosmetic in the lower container.

However, in this container, it is not easy to open the lid and the lower container.

Therefore, an operating member is slidably disposed in a slide hole provided in the upper container, and by pressing the operating member, the slope at the tip displaces the lid and the lower container up and down, and the lid and the lower container are moved up and down to engage with the upper container. A container was proposed that could release the lock. However, this container has a thick upper body due to the provision of the slide hole, and the structure of the slide hole and the operating member is complicated, leading to high costs.

The present invention aims to provide a container in which the lid and the lower container can be opened easily and reliably in one operation, the upper container can be formed thinly, and the container can be manufactured at low cost.

Next, embodiments of the present invention will be described based on the accompanying drawings.

The figure shows a compact container. This is made up of an upper container 10, a lid 12 and a lower container 14 arranged above and below the container, which are connected by a hinge 16 so as to be openable and closable. That is, a cutout 18 is provided on the back side of the upper container 10, and the support pieces 1 are inserted from the bottom of both sides of the cutout.
9, 19 are provided to protrude downward, and both support pieces 19, 1
The hanging piece 13 of the lid body 12 is fitted inside the lid body 9, and the notch 15 of the lower container is fitted on the outside thereof, and a hinge pin 17 passes through these three pieces.

The upper container 10 has a cosmetic storage recess 2 in the center.
It has 0. At a position corresponding to the hinge notch 18 in the peripheral edge 22 of the upper container 10, a notch recess 24 that is open in the vertical direction and outward is provided.

This notch recess 24 is made up of a back surface 26 and side surfaces 28, 28 that are orthogonal to this and face each other. Locking protrusions 30, 32 are formed on the upper and lower sides of the inner surface 26, and as described later, these locking protrusions 30, 3
2 are configured to be able to engage with the corresponding engagement protrusions 54 and 64 of the lid body 12 and the lower container 14. In addition, protrusions 34, 34 are provided on both side surfaces 28, 28 of the cutout recess 24, facing each other and protruding in the horizontal direction, and their tips are rounded off to form a forward-facing slope 36.

Reference numeral 38 denotes a bridge piece, which is formed into a generally U-shaped cross section by a slightly outwardly curved rectangular pressing piece 40 and protruding pieces 42, 42 extending from both ends thereof. Each projection 42 has a fitting hole 4.
4 are provided. The bridge piece 38 is given elasticity as a whole by such a shape, and in this case,
It is preferable if the bridge piece 38 is made of plastic, as this will provide greater elasticity.

Although the shape of the pressing piece 40 is not limited to the above-mentioned shape, it is preferable that the shape corresponds to the shape of the peripheral edge of the upper container 10. For example, the pressing piece 40 is formed into a slightly outwardly curved rectangular plate, and the notch recess 24
It is also possible to construct the structure on both sides 28, 28 of the structure.

The bridge piece 38 is disposed within the notch recess 24 of the upper container 10, and is connected to the pressing piece 40 and the notch recess 24.
A space is formed between the inner surface 26 and the inner surface 26 of the inner surface. At this time, the projection 34 of the upper container 10 is fitted into the fitting hole 44 of the bridge piece 38.

When assembling this container, the bridge piece 38
is press-fitted into the notch recess 24 from outside using the elasticity of the bridge piece itself. In this case, if the tip of the protrusion 34 is formed into the slope 36 as described above, the protrusion 34 can be smoothly fitted into the fitting hole 46.

The lid 12 has a peripheral edge 49 at a position corresponding to the notch recess 24 of the upper container 10, that is,
It has a hanging part 50 on the front side. The outer surface of the hanging portion 50 is curved inward to form an arcuate slope 52.
Further, an engaging protrusion 54 is provided on the inner surface of the hanging portion 50. 56 is a mirror provided on the lower surface of the lid body 12.

The lower container 14 has a puff storage recess 58 in the center, and a standing portion 60 is provided in a peripheral portion 59 at a position corresponding to the hanging portion 50.
The outer surface is formed as an arcuate slope 62, and an engaging protrusion 64 is provided on the inner surface.

In the closed state of the container, the hanging part 50 and the upright part 60 are located in the space between the pressing piece 40 and the inner surface 26, and the locking protrusion 30 is located at the engagement protrusion 5 of the lid.
4, and the locking protrusion 32 engages with the engagement protrusion 64 of the lower container. Further, both upper and lower ends 46 and 48 of the pressing piece 40 are in contact with slopes 52 and 62, respectively. However, the means for engaging the lid, upper container, and lower container in the present invention are not limited to those described above, and any appropriate means can be employed.

When opening the lid 12 and lower container 14 of this container, the following operations are performed.

When the pressing piece 40 of the bridge piece 38 is pressed, the pressing piece 40 is bent as shown by the two-dot chain line in FIG. 1 and advances inward to the position shown by the solid line in FIG. 3. At this time, the upper and lower ends 46 and 48 of the pressing piece 40 come into pressure contact with the slope 52 of the lid body 12 and the slope 62 of the lower container, and press these in the vertical direction, thereby separating the lid and the lower container. by displacing it up and down, and
As shown in the figure, the locking protrusions 30, 32 of the upper container
, an engagement protrusion 54 on the lid, and an engagement protrusion 6 on the lower container.
4 is released.

In this manner, in the container of the present invention, both the lid 12 and the lower container 14 can be easily opened by one action of pressing the pressing piece 40.

In addition, in FIGS. 2 and 3, 66 is a cosmetic, 67 is a storage tray thereof, and 68 is a puff.

The shapes of the slopes 52 and 62 are not limited to those described above. Also, depending on the shape of these slopes,
If both the upper and lower ends 46 and 48 of the pressing piece 40 are also formed in an inclined shape, the pressing piece can be pushed in and released easily.

Further, the container of the present invention is not limited to a compact container, and can be applied to other uses as well.

As is clear from the above description, the present invention has the following effects.

1. In a container having a double structure of an upper container and a lower container, both the lid and the lower container can be opened easily and reliably by pressing a bridge piece disposed on the upper container in one motion.

2 There is no need to provide a slide hole in the upper container,
The upper body can be made thin.

3. The structure of the bridge piece and upper container is simple and can be manufactured at low cost.
