Description

[Detailed Description of the Invention] [Industrial Field of Application] 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-layer structure.

[Prior art and its problems]

Conventionally, the above-mentioned containers include a lid, an upper container,
A container is known in which the lower container is hinged and provided with locking means such as engagement protrusions on the periphery of each to maintain the closed state. The opening operation is not easy.

Therefore, it has been proposed to provide an operating member on the front side of the upper container that slides in the inner and outer directions of the container, and to open the lid and the lower container vertically using slopes formed at the top and bottom of the tip of this operating member. (See Figure 6).

However, when opening this container,
By grasping the entire container with your fingers, holding your fingers in contact with the hinge portion provided on the back side of the container, and pressing the operating member toward the back side with your thumb, the lid body and lower container are centered around the hinge pin. attempt to rotate backwards. At this time, a force is exerted that presses the rear ends of the lid and the lower container forward, making it difficult to open the lid and the lower container smoothly.

Further, as a locking means for maintaining the closed state of the upper container, the lid body, and the lower container in a container equipped with an operating member that is slidable in the inward and outward directions on the front side of the upper container, particularly, As shown in FIG. 6, engaging protrusions 2a and 2b are provided on the upper and lower front surfaces of the upper container 1, and a locking protrusion 4a is formed on the inner surface of a hanging portion provided at the front end of the lid 3, A locking protrusion 4b is formed on the inner surface of the upright portion of the container 5, and these locking protrusions 4a, 4b are connected to the engagement protrusion 2, respectively.
A and 2b are often used, but when the operating member 6 is pressed inward to open the lid 3 and the lower container 5, the engagement The locking protrusions 4a and 4b are pushed up in the direction of arrow A, and these locking protrusions 4
When a, 4b climbs over the engagement protrusions 2a, 2b, strong stress is generated in these locking means 2a, 2b, 4a, 4b, and the locking means are likely to be damaged.

Furthermore, when using these containers, it may be desirable to open either the lid or the lower container. For this reason, for example, as shown in Figure 6,
The slope 7a provided at the top of the operation member 6 is formed to have a gentler inclination angle than the slope 7b provided at the bottom of the operation member 6, so that when the operation member 6 is pressed, the lower container 5 opens first. However, in this case, the lid 3 does not open until the lower container 5 is opened, and it is impossible to open only the lid 3. Furthermore, even when opening only the lower container 5, it is necessary to stop the pushing operation of the operating member 6 midway through, and the pushing operation is not easy. is inconvenient. Moreover, in a case where the lid 3 is configured to open first, contrary to the above-mentioned case, there is an inconvenience similar to the above-mentioned case.

[Means for solving problems]

In order to solve the above problems, the present invention provides at least two operating members that can reciprocate in a substantially horizontal direction along the circumferential surface of the upper container, and one of these operating members has an upwardly directed Set up a slope,
The other side is provided with a downward slope, and a downward slope is formed at a position corresponding to the upward slope of the operating member on the peripheral edge of the lid, and the downward slope corresponds to the downward slope of the operating member on the peripheral edge of the lower container. It is formed by forming an upward slope at the position where the

[Effect]

In the present invention, by pressing at least two operating members disposed on the upper container in a substantially horizontal direction along the circumferential surface of the upper container, the upward slope provided on one operating member is pressed against the peripheral edge of the lid body. It comes into contact with the provided downward slope and pushes it up, thereby displacing the lid upward to release the engagement between the upper container and the lid, release the lid from the upper container, and operate the other side. The downward slope provided on the member comes into contact with the upward slope provided on the peripheral edge of the lower container and pushes it down, thereby displacing the lower container downward and releasing the engagement between the upper container and the lower container. The lower container is opened from the upper container, and the lid and the lower container can be opened simultaneously or separately from the upper container.

[Effect of idea]

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, the lid and the lower container can be easily and reliably operated at the same time, or either one, by pressing the operating member disposed on the upper container with one movement. can be opened to

2. When opening the lid and the lower container, the operating member is pressed in the horizontal direction of the container, and there is no need to hold the container by touching the hinge part on the back side of the container. Therefore, the lid and the lower container can be opened smoothly.

3. During the opening operation of the container, since the operating member is not pressed inward of the container, no strong stress is applied to the locking means such as the engagement protrusion, and damage to the locking means can be prevented.
