Description

[Detailed Description of the Invention] The present invention relates to a compact container whose lid is locked and unlocked by rotational movement.

In conventional general compact containers, the lid is pivotally attached to the container body so that it can be opened and closed, and the lid is locked and unlocked by a first protrusion formed on the front end claw of the lid. This is done by climbing over a second protrusion formed on the front end wall surface of the main body. Therefore, if the amount of protrusion of both protrusions is larger than a predetermined value, engagement will be difficult, and conversely, if the amount of protrusion is smaller than a predetermined value, engagement will be incomplete and the lid will open inadvertently. I will do it. Therefore, the amount of protrusion of both protrusions must be extremely accurate, and the utmost care is taken during molding. However, due to dimensional variations and deformations that inevitably occur during actual molding, the amount of protrusion of both protrusions also varies, resulting in a relatively large number of defective products.

The present invention was developed in view of the above-mentioned defects in the locking and unlocking structure of compact containers.The purpose of this invention is to lock and unlock the compact container by rotational movement, and to avoid the conventional strict process during molding. The purpose is to provide a compact container that does not require dimensional accuracy.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 indicates a container body, and a circular cosmetic storage recess 2 is formed in the center of the upper part of the container body 1. An annular wall 3 surrounding this recess 2 has a smaller diameter than a lower peripheral edge 4, and an annular frame 5 is disposed around the outer periphery of this annular wall 3.
An annular collar 6 projects downward from the bottom surface of the frame body 5, and a first annular projection 7 is formed on the annular collar 6. This annular projection 7 is formed on the inner peripheral surface of the lower peripheral edge 4 of the container body 1. The frame body 5 is engaged by passing over the second annular projection 8, and the frame body 5 is rotatable with respect to the container body 1. As shown in FIGS. 3a and 4a, on the front inner circumference of the frame 5, an arc-shaped space 9 is defined by its inner wall surface, and the front inner wall has a First and second engaging recesses 10 separated from each other
a and 10b are formed.

An annular wall portion 3 of the container body 1 facing this cavity 9
First and second engaging protrusions 11a and 11b protruding into the cavity 9 are provided on the outer periphery of the holder, and first and second stopper pieces 12a and 12b are provided on both sides of the engaging protrusions 11a and 11b.
is formed. The mutual positional relationship between them is such that in the first rotational position shown in FIG. Rotation after contact is regulated, and the first engagement protrusion 11a fits into the first engagement recess 10a, and conversely, the frame 5 is moved against the container body 1 by the other In the second rotational position shown in FIG. 4a in which the second stopper piece 12b is rotated in the
The rotation after contacting b is regulated, and
The second engagement protrusion 11b is adapted to fit into the second engagement recess 10b.

The lid 1 is attached to the rear end of the frame 5 by a horizontal pin 13.
4 is pivotally mounted, so that the lid body 14 can not only be opened and closed back and forth, but also rotate with the rotation of the frame body 5. A mirror 15 is bonded to the inner surface of the lid 14, and a hook-like protrusion 16 is formed to hang down from the front inner surface. As shown in FIGS. 3b and 4b, a notch hole 17 having a hook-like longitudinal section is formed at the edge of the annular wall 3 of the container body 1 in correspondence with this hook-like protrusion 16. There is.

Now, as shown in FIGS. 3a and 3b, when the frame 5 is rotated to the first rotational position with respect to the container body 1, the upper end opening of the hook-shaped notch hole 17 and the hook-shaped protrusion 16 are in contact with each other. The positions of the lower end hook portions 16a are aligned vertically, so that when the lid body 14 is closed, the hook-like protrusion 16 enters the hook-like notch hole 17.
From this state, move the frame 5 to the second position relative to the container body 1.
When the lid body 14 is rotated to the rotational position shown in FIGS. The lid body 14 is in a closed state. When the frame body 5 is rotated to the first rotational position again, the lock is released and the lid body 14 can be freely opened upward relative to the container body 1.

As is clear from the above description, in the compact container of the present invention, by rotating the frame 5 provided on the periphery of the container body 1, the hook-shaped protrusion 16 provided on the lid 14 and the container body 1 Since the locking and unlocking is performed with the hook-shaped notch hole 17 formed in Compared to conventional containers, strict dimensional accuracy is not required during molding, and compact containers can be easily molded and have an extremely low probability of producing defective products.
Further, since locking and unlocking are performed by the hook-shaped protrusion 16 and the hook-shaped notch hole 17, once the lock is locked, there is no risk of it being unlocked inadvertently, and locking is extremely reliable. Further, when unlocking, there is no need to pry open the lid as in the conventional case, and the lid can be opened extremely easily.

Additionally, as shown in the preferred embodiment of the present invention,
A circular arc-shaped cavity 9 is formed in the inner circumference of the frame 5, a pair of engagement recesses 10a and 10b are formed in the inner wall of the frame 5, and a pair of engagement protrusions is formed on the side surface of the container body 1 facing the cavity. parts 11a, 11b and a pair of stopper pieces 12
a, 12b, the frame 5
can be fixedly maintained in the locked position and the unlocked position, thereby making locking and unlocking even more reliable.
