Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight cosmetic container for easily storing cosmetics.

[0002]

2. Description of the Related Art Generally, a cosmetic container is used for carrying cosmetics, and the cosmetic container accommodates the cosmetic in the container body and is hinged to the rear end of the container body so as to be openable and closable. The lid body covers the upper side of the container body. The hook mechanism provided between the front end portions of the container body and the lid body holds the locked state of the lid body, and the operation portion for releasing the hook mechanism is provided at the front end portion of the container body. Has a general structure.

By the way, in this type of cosmetics container, a packing material is attached to the back surface of the lid, and when the lid is closed, the interior of the decorative plate filled with the cosmetic is sealed. For example, as shown in FIG. 12, the packing material 2 attached to the back surface of the lid 1 is provided with an annular projection 2a having a diameter slightly larger than the inner diameter of the decorative plate 4 fitted to the container body 3, and the lid 1 This annular projection 2a is closed by closing the
By being configured to be press-fitted to the inner peripheral surface,
The interior of this decorative plate 4 is kept airtight.

[0004]

However, in such a conventional airtight cosmetic container, as described above, the annular projection 2a protruding from the packing material 2 is pressed into the inner peripheral surface of the decorative plate 4. The airtightness of the interior of the decorative plate 4 is ensured. At this time, by setting the outer diameter of the annular protrusion 2a to be slightly larger than the inner diameter of the decorative plate 4, the inner peripheral surface of the decorative plate 4 is press-fitted. It is configured to secure. Therefore, each time the lid 1 is opened and closed, the annular protrusion 2a rubs against the inner peripheral surface of the decorative plate 4, and in particular, it is close to a hinge (not shown) in which the lid 1 is attached to the container body 3 in an openable and closable manner. The annular projection 2a in the portion is largely worn, and thus the packing material 2 is heavily worn, so that there is a possibility that the airtightness may be deteriorated in a short-term use.

Since the annular projection 2a is press-fitted to the inner peripheral surface of the decorative plate 4, a large closing force is required to close the lid 1, and the lid 1 is closed. When opening from the state, the annular projection 2a is placed on the decorative plate 4
Since the packing material 2 is pulled up in a state of being pressed against the inner peripheral surface, the inside of the decorative plate 4 becomes a negative pressure, and a great force is required to open the lid 1 against this negative pressure. In short, from these things, there is also a problem that it is difficult to smoothly open and close the lid 1.

In view of such conventional problems, the present invention can open and close the lid body with light operability, prevent the packing material from being worn out due to the opening and closing operation, and guarantee excellent airtightness. An object is to provide an airtight cosmetic container that can be used.

[0007]

In order to achieve the above object, the present invention provides a container body, a lid body which is openably and closably provided on the container body, and a lid body attached to the back surface of the lid body. A packing material which covers the cosmetics storage portion of the container body in a locked state and seals the inside thereof, the packing material having an outer peripheral portion inside the cosmetics storage portion as the lid is closed. Forming a tubular annular projection to be inserted into the inner peripheral surface of the packing material, and forming a movable joint portion that moves the outer peripheral portion of the packing material inward from the position where the annular projection is formed, and the outer peripheral portion of the packing material. Between the container body and the container body, a tilting mechanism for tilting the outer peripheral portion of the packing material by locking the lid body to the container body is provided, and the outer peripheral portion of the packing material is locked by locking the lid body. With the tilt, the ring-shaped protrusion causes the cosmetic storage And configured to be pressed against the peripheral surface.

Therefore, in the airtight cosmetics container of the present invention, when the lid is closed in the operation process of closing the lid with respect to the container body and then locking the lid, the tubular ring-shaped packing material is used. The protrusion is only inserted into the cosmetics storage part, and when the lid is locked with respect to the container body after that, the tilting mechanism tilts the outer peripheral part of the packing material through the movable joint part by this locking operation. Then, only by this tilting, the annular projection comes into pressure contact with the peripheral surface of the cosmetics storage portion. That is, only by closing the lid, the annular protrusion of the packing material does not exhibit the airtight action with the cosmetics storage portion, and the airtight action is exhibited only when the lid is locked to the container body. It is like this.

More specifically, when the lid is closed, the annular protrusion of the packing material is inserted into the cosmetic material storage portion. In this state, when the lid body is locked to the container body, the lid body and the container body are further tightly packed, whereby the tilting mechanism tilts the outer peripheral portion of the packing material from the movable joint portion. Due to the tilting of the outer peripheral portion, the annular projection comes close to the cosmetics storage portion side and comes into pressure contact with the peripheral surface thereof. In this way, the annular projection is pressed against the peripheral surface of the cosmetics storage portion only when the lid body is locked with respect to the container body, so when opening / closing the lid body that is not in the locked state. , The ring-shaped protrusion is far from the cosmetics storage,
It is possible to prevent wear of the packing material due to the opening / closing operation without rubbing against it. Further, when the opening / closing operation is performed, the peripheral surface of the cosmetics storage portion does not rub against the annular protrusion, so that the lid can be opened / closed with light operability.

On the other hand, when the lid is opened, the outer peripheral portion of the packing material that has been tilted together with the restoration of the tilting mechanism along with the release of the locking mechanism is restored through the movable joint portion, thereby forming an annular protrusion. Is applied with a force in a direction away from the peripheral surface of the cosmetics storage portion, so that the pressed state of the two is relieved or disappears. Due to such an action, the airtight state in the cosmetics storage section is released so that the cosmetics storage section can communicate with the outside air, and the negative pressure inside the cosmetics storage section when the lid is opened is prevented. Can be opened with a light touch.

While realizing the excellent opening / closing operability as described above, the outer peripheral portion of the packing material is tilted from the movable joint portion by the tilting mechanism by locking the lid with respect to the container main body, whereby an annular shape is obtained. It is possible to secure the excellent airtight performance by pressing the projection close to the cosmetics accommodating portion side and pressing it against the peripheral surface thereof.
