Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic container,
In particular, the present invention relates to a structure in which a lid body can be opened and closed with respect to the container body by a pivoting operation around a hinge pin vertically penetrating one side portion of the container body and the lid body.

[0002]

2. Description of the Related Art Some cosmetic containers have a structure in which an upper lid horizontally pivots with respect to the container body to open and close the container body.
This is a structural type in which the inside of the container body is opened and closed by turning the lid body around a vertical axis that vertically extends through the container body and one side portion of the lid body. This structure type is required to have so-called free-stop property, in which when the lid is closed, it closely adheres to the container body to prevent scattering of cosmetics inside, and when the lid is opened, the lid stops at an arbitrary position. It

As an example for satisfying such a demand, as shown in Japanese Utility Model Publication No. 5-35792, there is one in which an inner lid is rotatably mounted on an upper portion of a container body around a longitudinal axis. . In such a cosmetics container, in addition to the inner lid, a lid is rotatably attached to one side of the container body, and the inner lid is pressed against the upper surface of the container body with the lid closed, and the container is closely attached to the container body. This prevents the cosmetics contained in the main body from splashing, while the inner lid floats from the container body when the lid is open, and a spring is placed around the shaft to facilitate turning. However, this spring force always urges the inner lid in the direction of separating from the container body. Further, the free stop property is achieved by the pressing force of the spring.

[0004]

However, in such a structure, the lid is double, and the structure becomes complicated. Further, in this structure, a force is applied in the direction to always separate the inner lid, so that it is a small-sized cosmetics container, and the purpose is to configure the lid as a single body and bring it into close contact with the container body with the lid closed. Cannot fit.

The present invention has been made to solve the above-mentioned problems, and its object is to make it possible to improve the airtightness of the inside by adhering to the container body when the lid is closed by the turning operation, due to the simple structure. The object of the present invention is to provide a free-stop property when opened, and to provide a cosmetic container that can obtain a cushion property when an external force other than the opening and closing of the lid such as a twist is applied.

[0006]

In order to achieve the above-mentioned object, according to the present invention, a pin vertically provided on the lower surface of one side of a lid is inserted into a pin hole formed on one side of the container body, In a cosmetic container that opens and closes the lid body by sliding the lid body around the pin, an enlarged diameter portion is formed at the lower portion of the pin hole, and an outer circumference of the pin protruding to the enlarged diameter portion. A locking portion formed in a tapered shape in a large diameter is integrally formed on the portion, and an elastic tube is press-fitted from the lower portion of the expanded diameter portion to the outer periphery of the pin, and the locking portion and the end surface of the expanded diameter portion are formed. The elastic tube is held in a vertically compressed state between the two.

Therefore, according to the above structure, the structure is extremely simple. Then, due to the repulsive elasticity due to the compression of the elastic tube, in the closed state, the lid body is attracted to the container body side and adheres so as to enhance the airtightness, preventing deterioration of the cosmetics, while in the opened lid state. A free stop property can be obtained by the elastic force in the retracting direction.

Further, according to the present invention, a positioning projection higher than a fitting surface with the lid is circumferentially formed around the recess for storing cosmetics formed on the upper surface of the container body, and the lid is provided. Since the positioning concave portion that engages with the protrusion is formed at the center of the grinding surface, the lid positioning can be achieved with a simple structure, and the sealing performance at the time of closing the lid can be improved.

[0009]

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Figure 1,
2 (a) and 2 (b) show a small compact container as a cosmetic container according to the present invention. The size of this compact container is small enough to fit in the palm, and the container body 10
And a lid 20 that horizontally swivels the upper surface of the container body 10 so as to open and close. The container body 10 is a flat and substantially square container having rounded corners, which is made of a colored synthetic resin injection-molded article, and has a recess 11 for storing cosmetics having a similar shape to the center of the upper surface thereof. There is.

The lid 20 is a flat transparent plate having a substantially square shape similar to the outer shape of the container body 10 made of a synthetic resin injection molded body, and a pin 21 serving as a turning center is provided at a lower portion of one corner portion thereof. It is projected integrally. A small diameter portion 21a is formed in the middle portion of the pin 21, and a lower portion of the small diameter portion 21a is
A locking portion 22 having a larger diameter than this and formed in a tapered shape toward the lower side is integrally provided.

On the other hand, a pin hole 12 is opened at one corner of the container body 10 and penetrates to the lower part. The pin hole 12 has three stages, and the uppermost portion has a shaft hole 1 having a size comparable to the diameter of the root portion of the pin 21 and the diameter of the locking portion 22.
It functions as 2a, the middle part is a first expanded diameter part 12b having a larger diameter than this, and the lowermost part is a second expanded diameter part 12c having a larger diameter than this. And the first expanded portion 12
b functions as a supporting hole for the elastic tube 23 mounted on the outer periphery of the pin 12, and the second expanded diameter portion 12c functions as an insertion hole for the jig 30 for press fitting.

3 (a), 3 (b) and 4 (a),
FIG. 3B shows a procedure for inserting the pin 21 into the pin hole 12 and attaching the elastic tube 23 to the outer periphery of the pin 21. First, as shown in FIG.
The container body 10 and the lid 20 are fixed in a closed state in this state. On the other hand, when the press-fitting jig 30 holding the elastic tube 23 is inserted from the lower side to the tip, as shown in FIG.
As shown in FIG.
2 is inserted into the outer circumference of the small diameter portion 21a along the tapered surface,
As shown in FIG. 4A, the diameter of the locking portion 22 is reduced by climbing over the locking portion 22, and the diameter is settled within the first enlarged diameter portion 12b.

Then, when the jig 30 is removed, as shown in FIG.
As shown in FIG.
It is held in a compressed state between the end surface of 2 and the end surface of the first expanded diameter portion 12b, and due to its repulsive elasticity, an elastic force for always pulling the pin 21 toward the container body 10 side is exerted, and as a result, the lid 20 Always adheres to the upper surface of the container body 10 in an airtight manner.

Further, a positioning convex portion 14 is formed at the periphery of the cosmetics accommodating concave portion 11 so as to rise obliquely from the periphery thereof, while the convex portion 14 is engaged with the central portion of the lapping surface of the lid body 20. The matching recess 24 is formed in an inclined state (see FIGS. 3 and 4). As described above, in particular, as shown in FIG. 2A, the closing position of the lid 20 is positioned, and when the two squares are made to coincide with each other, the creeping distance is increased due to the slanting of the inclined surfaces to close the lid. Improves the internal airtightness in the lid state.

Further, when the lid 20 is opened laterally from the closed state, the lid is opened as shown in FIG. 2B with a slight resistance when the concave portion 24 is pulled out from the convex portion 14. It On the contrary, when closing the lid, the concave portion 24 is pulled into the convex portion 14 and is closed in a stable state with a slight shock or a click sound, so that it is felt that the lid is closed at the normal position. You can check it.

Although the fully opened state is shown in FIG. 2 (b), the lid 20 can be stopped at any position when the lid is opened, and so-called free stop property can be obtained.
This is because the elasticity of the elastic tube 22 always causes the lid 20 to
This is because the force of pulling the
It is also possible to prevent inconvenience in use due to unexpected movement when tilted. Further, even if an external force other than the turning operation, such as a twisting force, is applied, the pin 21 can be prevented from being broken due to the cushioning property of the elastic tube 23.

[0017]

As is apparent from the above description, the cosmetic container according to the present invention has a simple structure, and when the lid is closed by the turning operation, the cosmetic container is airtightly adhered to the container body to scatter the cosmetics. It is possible to prevent the deterioration thereof and its deterioration, to obtain a free-stop property at the time of opening, and a cushion property when an external force other than the opening and closing of the lid such as a twist is applied.
