[Problem that the invention attempts to solve]

However, in such a conventional structure, the push buttons 39, 53, and 54 for opening the lid are provided at predetermined positions;
Since the pressing area of 3 and 54 is extremely small compared to the area of the entire container, a specific way of holding the container is required when opening the lid, resulting in a problem of lack of operability.

This invention was made in view of the above matters,
To provide a container structure that does not require a specific style for opening the lid and allows the lid to be easily opened from any direction.

[Means for solving problems]

In order to solve this technical problem, this invention
A container 1 and a circular mouth portion 2 provided on this container 1,
Lid base 3 that can be attached rotatably in the circumferential direction
and a lid body 4 pivoted to one side edge of the lid base 3 so as to be openable and closable. An engaging portion 9 is provided in a protruding manner.

The lid base 3 has a circular opening 10 corresponding to the mouth 2 of the container 1, and is formed with a concave or convex shape on the bottom surface so as to correspond to the concavities and convexities of the guide part 5. 5, and a through hole 12 was formed at a position corresponding to the engaging portion 9 of the container 1.

The lid body 4 has an opening side edge 4a.

The contact surfaces between the engaging portion 9 and the pressed portion 14b are tapered so that they separate from each other when a relative positional shift occurs between the two.

As a result, when the lid base 3 is rotated in either direction with respect to the container 1, the pressed portion 14b that is in a fitted state with the engaging portion 9 rides up from the engaging portion 9 and is pushed up, and the lid 4 It was designed so that the lid could be opened.

[Effect]

The lid base 3 has a fitting part 11 provided on its bottom surface.
is rotatably fitted into the guide portion 5. This prevents the lid base 3 from coming off.

When the lid is closed, the locking portion 14a on the lid body 4 side
is locked in the through hole 12, and the pressed part 14a
comes into contact with the engaging portion 9, and the lid body 4 is locked.

On the other hand, when the lid base 3 is rotated in either direction relative to the container 1, the engaging portion 9 and the pressed portion 14
Since the contact surface with b is provided with a taper that separates from each other when a relative positional shift occurs between the two, the pressed part 14b is pushed up to overcome the engaging part 9 and separated. However, along with this, the locking between the locking portion 14a and the through hole 12 is released, and the lid is opened.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 6.

First, as an overview, a lid base 3 is attached to the mouth 2 of a container 1 so as to be rotatable in the circumferential direction, and a lid 4 is pivoted to one side edge of the lid base 3 so as to be freely openable and closable. It is configured as a cosmetic compact.

A guide portion 5 is provided protruding along the circumferential edge of the circular mouth portion 2 formed in the container 1, and an engaging protrusion 5a is provided on the outer circumferential edge of the guide portion 5.
is formed. A groove 6 having protrusions 6a, 6a protruding from the bottom surface is formed inside the guide portion 5, and a partition wall 8 of the accommodating portion 7 is erected inside the groove 6.

On the upper edge of the guide portion 5, an engaging portion 9 formed in a substantially rectangular shape projects in the lateral direction, and a recess 9a is carved in the upper edge of the engaging portion 9.

This recess 9a has a tapered surface that slopes upward on both sides of the center point.

A lid base 3 attached to the mouth 2 of the container 1
is provided with an opening 10 corresponding to the mouth 2, and has a fitting portion 11 on its bottom surface that rotatably fits into the engaging protrusion 5a. This fitting part 11 is formed with a groove 11a into which the engaging protrusion 5a is slidably fitted, and by pressing this into the guide part 5, the lid base 3 and the container 1 can be freely rotated. will be integrated into. A leaf spring 11b is provided vertically at the edge of the opening 10, and by positioning the leaf spring 11b between the protrusions 6a, 6a, the lid base 3 is always held in a neutral position. ing. Furthermore, a long through hole 12 is provided in the lid base 3 at a position corresponding to the groove 6, and an engagement recess 12a is carved in the through hole 12.

Hinge holes 13, 1 are provided at the rear edge of the lid base 3.
3 is provided, and this hinge hole 13,
A gouged portion 13a is formed so as to be inscribed in a virtual cylinder having axis 13.

The lid body 4 that is pivoted to the lid base 3 is attached to the lid base 3.
It is formed to cover the upper surface, and an engaging tongue piece 14 corresponding to the through hole 12 is vertically provided on the opening side edge 4a. A locking portion 14a is formed on the side surface of the locking tongue piece 14 and locks into the locking recess 12a in the through hole 12 formed in the lid base 3. Furthermore, a pressed portion 14b that engages with the engaging portion 9 through the through hole 12 is formed at the lower end of the engaging tongue piece 14.

The pressed portion 14b is a convex portion opposite to the recessed portion 9a, and has a tapered surface that slopes downward from the center point.

Therefore, if a relative displacement is caused in the contact surfaces of the engaging portion 9 and the pressed portion 14b,
The engaging portion 9 and the pressed portion 14b are separated from each other by passing over the tapered surfaces.

A hinge portion 15 formed in a substantially cylindrical shape is provided on the shaft side edge 4b of the lid body 4, and is rotatably fitted into the hinge holes 13, 13 on both sides of the hinge portion 15. Pins 16, 16 are formed in a protruding manner.

Note that in the above configuration example, the guide portion 5 and the corresponding fitting portion 11, and the partition wall 8 and the corresponding opening portion 10 were provided independently, but this is not limited to this example. As shown in FIG. A, by using the partition wall 8 also as the guide part 5 and the opening part 10 as the fitting part 11, the shape can be simplified.

An example of the operation of the above configuration will be explained based on FIG. 4.

First, when closing the lid, by pressing the top surface of the lid 4, the locking part 14a locks into the engagement recess 12a, and the pressed part 14b fits into the recess 9a, so that the lid 4 is locked. (Figure 4A).

On the other hand, when the lid base 3 is rotated relative to the container 1 when the lid is opened, the lid 4 and the container 1 are rotated relative to each other. At this time, a relative positional shift occurs between the abutting surfaces of the engaging part 9 and the pressed part 14b, so the tapered surfaces mentioned above cross over each other, and the engaging part 9 and the pressed part 14b are moved over each other. It is separated from the portion 14b.

Therefore, the pressed portion 14b is pushed up and removed from the recess 9a (FIG. 4B). This results in
The engagement between the locking portion 14a and the engagement recess 12a is released, and the lid is opened.

When the user releases the lid base 3, the lid base 3 is returned to the neutral position by the elastic force of the leaf spring 11b.

In this way, the lock can be released simply by rotating the lid base 3 in some way,
Good operability.

Note that the pressed portion 14b and the tapered surface formed in the recessed portion 9a may be formed in a shape that separates as a result of a change in their relative positions. Specifically, as shown in FIG. The tapered surfaces can have a mountain shape and a valley shape, respectively.

Further, the guide portion 5 does not necessarily have to be formed in an annular shape, but may be formed independently in three directions as shown in FIG. You can also do it.

Further, in the above-mentioned embodiment, the container 1 is made thin so that it can be used as a compact device, but this is not limited to this example. , the scope of use can be expanded.

[Effect of idea]

According to the present invention, the locking state of the lid body can be released by simply rotating the lid base in either direction, so there is no need to operate the small-area push button like in conventional systems. The lid can be opened from any direction.

Furthermore, since it can be configured with a total of three parts, the number of parts does not increase and it can be easily implemented.
