Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight compact container.

[0002]

2. Description of the Related Art Many of the solid cosmetics represented by foundations, powders, eye shadows, etc. contain volatile components, but conventional compact containers have poor airtightness, so volatile components disappear and However, there is a problem that they tend to dry or shrink and crack. As measures against this, conventionally, Japanese Utility Model Laid-Open No. 63-129512 (hereinafter referred to as Prior Art 1), Japanese Utility Model Laid-Open No. 3-119315 (hereinafter referred to as Prior Art 2), and Japanese Utility Model Laid-Open No. 4-airtight compact container 41316 (hereinafter Prior art 3) is known. In the prior art 1, an outer lid that covers the entire surface of a main body having a cosmetic storage portion is pivotally attached, and an inner lid that can cover the cosmetic storage portion is pivotally attached to the outer lid. A movable lid, which is movably supported in the vertical direction via an elastic body, is attached, an elastic packing that can contact the outer edge of the cosmetics storage section is fixed to the movable lid, and the inner lid is pressed when closing the outer lid. Thus, the elastic body is compressed to press the movable lid, and the elastic packing is used for sealing. In prior art 2, a male screw-shaped ridge is arranged on the outer periphery of an annular wall on which a cosmetic material containing drum is fitted on the main body, while an annular wall is formed on the inner surface of the lid, and the male screw-shaped ridge is formed on the inner wall. A female screw ring having a female screw-shaped ridge capable of being screwed therein is rotatably held, and a ring packing for contacting the flange with the cosmetic material containing drum is attached inside the lid body on the inner diameter side of the short cylinder. The peripheral wall of the lid is absent to expose a part of the female threaded ring, and the female threaded ring is screwed onto the female threaded ridge to achieve sealing. Prior art 3 attaches an inner frame having a fitting portion for a cosmetic drum to a main body to which a lid is pivotally attached, and a push-type lid opening / closing button having an engaging portion between the front portion of the inner frame and the front portion of the main body. On the other hand, the inner surface of the lid body is provided with a packing capable of contacting the flange of the cosmetic drum, and a latching piece engaging and disengaging with the engaging portion, and the middle frame is a window allowing the passage of the latching piece. By providing a hole and closing the lid, the latching piece is engaged with the engaging portion and the packing is brought into close contact with the flange of the cosmetic drum.

[0003]

However, in any of the prior arts, when the lid is opened, the seal for the cosmetics is released. Therefore, when the lid is opened during use and left as it is, the cosmetics are left untouched. There was a problem that the volatile component of the was evaporated. Further, the prior art 1 is expensive due to the complicated structure using the inner lid, the movable lid and the elastic body, and the sealing performance is influenced by the pressing force of the inner surface of the outer lid. There has been a problem that the airtightness is likely to be incomplete due to a dimensional error between the projecting pedestal part and the inner surface of the lid and a secular change of the elastic body. Further, in the prior art 1, since the area of the mirror cannot be made large, and when the mirror is made large, the mirror comes into contact with the pressure receiving projection of the inner lid every time it is opened and closed, and thus the mirror has an indentation or the inner lid. There was a problem that the attached cosmetic was transferred to the mirror and the mirror became dirty.

Prior art 2 also has a special and very complicated structure, and since half of the female thread ring is exposed to the outside, the simplicity and smartness of the appearance, which is important as a cosmetic container, is impaired, and screwing is performed. Since this method is used, there is a problem that a considerably large operating force is required to open and close the lid. Further, since the female screw ring occupies a half area of the inner surface of the lid, there is a problem that the area where the mirror can be provided becomes small and it becomes difficult to visually check the makeup condition.

The prior art 3 has a problem that the packing is fixed to the inner surface of the lid, so that the appearance is not good and that a gap is generated when cosmetics or a foreign substance adheres to the packing to deteriorate the sealing property. Similar to the technique 2, since the packing occupies the half of the inner surface of the lid, there is a problem that the mirror can be provided only in a small area of about half of the lid.

The present invention was devised to solve the above-mentioned problems, and its purpose is to have a simple structure while keeping the external shape as simple as an ordinary one. Airtightness can be achieved,
Another object of the present invention is to provide an airtight compact container that can be provided with a large mirror surface that is easily visible on the inside of the lid.

[0007]

In order to achieve the above object, the present invention provides a main body having a lid pivotally attached to a rear portion thereof, an inner frame having a fitting hole for a cosmetic drum and attached to the main body, and In a compact container of a type having an inner lid which is pivotably attached to a middle frame so as to be capable of undulating and a packing capable of contacting the flange of the cosmetic drum is attached to the lower portion, a horizontal protruding portion is formed on the inner lid at a lower portion. And a notch allowing the mounting and dismounting of the lever are provided in proximity to the middle frame, and an operating portion protruding from the long hole and the operation part protruding from the long hole are provided on the lower surface side of the middle frame. In this structure, a slider for locking the inner lid, which has a stopper portion that can advance to the horizontal protruding portion of the lever, is arranged. The operation portion may have a length reaching the lid locking portion on the front portion of the main body when the lock is released.
Further, the horizontal protruding portion may have a protrusion or a concave groove on the upper surface, and the concave groove or the protrusion that can be engaged with and disengaged from the horizontal protrusion may be provided on the upper surface of the stopper portion.

If the inner lid is turned down, the lever enters the inner frame through the notch of the inner frame, and if the movement operation section is operated in this state, the inner lid locking slider including this slides and the stopper section is opened. Extend onto the horizontal protrusion at the bottom of the lever. Therefore, the horizontal protrusion is pressed downward, the opening of the cosmetic drum is sealed by the packing, and the inner lid cannot be opened. That is, in the present invention, the inner lid is locked with the seal independently of the opening of the lid, and the inner lid does not automatically open even when the lid is opened. Therefore, good airtightness can be maintained even when the lid is left open. And since the lid does not participate in the sealing and unsealing of the inner lid, and the gap can be set between the lid and the upper surface of the inner lid, the mirror can be largely attached to the entire inner surface of the lid, making it easy to visually check the makeup state. Moreover, even if the cosmetic material adheres to the surface of the inner lid, the mirror is not soiled by this. Furthermore, since the inner lid locking mechanism uses a part of the inner lid and the inner lid locking slider that cooperates with this is arranged in the space below the inner frame, the compact structure with a conventional inner lid and external appearance The shape can be simple and smart, and the structure is simple and the cost can be low.

[0016]

Operation of the Embodiment Next, the operation of the embodiment and the use condition will be described. First, the assembly of the airtight compact container according to the present invention will be described. The lid 2 is pivotally attached to the main body 1 in advance,
The inner lid 4 is pivotally attached to the inner frame 3. And the base 1 of the main body 1
The slider 5 for locking the inner lid is placed on e, and the guide lever 5b
Is fitted into the slot 10. In this state, the middle frame 3 is arranged on the upper surface of the main body 1 and the main portion following the flange is fitted. At this time, the operating portion 5c projects upward from the elongated hole 30 of the middle frame 3. When the middle frame 3 is assembled, the space between the divided surrounding walls 33, 33 is positioned by fitting the protrusions 1a, 1a rising from the bottom of the main body 1, and the protrusions 1a, 1a and the respective divided portions. An annular holding portion is defined by the surrounding walls 33, 33.
Therefore, when the cosmetic drum A is fitted into the opening 3a of the middle frame 3, the flange a of the cosmetic drum A is supported by the annular recess 32 as shown in FIG. Since the undercut portions 100 of 1a and 1a are engaged, the cosmetic drum A is stably held.

With this, the cosmetic container is completed. In this state, in order to hermetically seal the cosmetic material filled in the cosmetic drum A, the inner lid 4 is closed and the operation portion 5c projecting from the inner frame 3 is locked. It should be pressed to the side where is displayed. First, the lever 4c at the front end passes through the cutout portion 31 of the middle frame 3 as the inner lid 4 is laid down, and the packing 7 on the lower surface of the inner lid 4 becomes the flange a of the cosmetic drum A.
And the horizontal protrusion 40 at the lower part of the lever is positioned inside the recessed receiving seat 11 of the main body 1. This state is shown in Figure 5.
In (a), the lower surface of the horizontal protrusion 40 is not in contact with the bottom of the recessed receiving seat 11, and the upper surface thereof is appropriately floated above the upper surface level of the recessed receiving seat 11. When the operating portion 5c is pressed in this state, the guide lever 5b moves along the groove hole 10, so that the stopper portion 5a is provided on the upper surface of the base portion 1e and the concave groove 3 of the middle frame 3.
It moves in a stable manner while in sliding contact with 5. As a result, the stopper portion 5a reaches the horizontal protrusion 40 of the lever 4c and presses it downward. As a result, the inner lid 4 is pulled downward via the lever 4c, so that the packing 7 is compressed and comes into close contact with the flange a of the cosmetic material drum A.
A reliable sealed state is formed as shown in (b) and FIG. 5 (b). In this state, even if an attempt is made to lift the handle portion 4b of the inner lid 4, the stopper portion 5a is located on the horizontal protrusion 40 of the lever 4c, so that the inner lid 4 cannot be opened. Moreover, since the locked state of the inner lid 4 is separated from the opening / closing of the lid body 2, even if the lid body 2 is inadvertently left open, the inside of the cosmetic drum A is kept airtight, so that the makeup is kept. The volatiles of the material do not evaporate. Therefore, stable quality can be maintained for a long period of time.

When using the cosmetics, the operating portion 5c may be moved to the OPEN display position again. By doing this, the stopper portion 5a and the guide lever 5b are retracted, the stopper portion 5a and the horizontal protrusion 40 of the lever 4c are disengaged, and the lock is released.
The inner lid 4 is opened by pinching and lifting b, and the exposed cosmetic material can be applied using the applicator B to apply makeup. According to the present invention, since the mirror 2b can have a large area (the inner lid 4 is not pressed by the pressing of the lid body 2 and no packing is provided on the inner surface of the lid), it is easy to visually check the makeup state. 2b can be fully used to apply the desired clean makeup. Also, when the cosmetic drum A is taken out from the holding portion for replacement, the notch 31
Since it is possible to insert the fingertip into and lift the flange a, it can be easily performed. That is, the notch 31 can be shared as a replacement operation part of the cosmetic drum A, and it is not necessary to separately provide a replacement dent or notch as in the conventional case.

In the second embodiment, the operation section 5c is set to OP.
When it is moved to the display position of EN, the end of the operation portion 5c goes over the end of the middle frame 3 and the recessed portion 1c as shown in FIGS. 7 and 8B.
Is located above the hook 101 of the. In this state, the lid 2
Even if the hook 201 is closed, the hook 201 comes into contact with the operation portion 5c, so that the engagement between the hook 201 and the hook 101 is prevented. Therefore, forgetting to lock the inner lid 4 can be surely avoided, and the lid 2 can be kept in a safe state where airtightness is always maintained.
Can be closed.

Further, as shown in FIG. 9, when the protrusion or the groove 41 is provided on the upper surface of the horizontal protrusion 40 and the groove or the protrusion 51 is provided on the upper surface of the stopper portion 5a, the stopper portion 5 is formed.
When moving a, the ridge or groove 41 and the groove or ridge 51
Engages with the snap, the feel is transmitted to the hand, and it is possible to reliably determine that the locked state is achieved. Further, when locked, the horizontal protrusion 40 and the stopper 5a are brought into close contact with each other by the reaction force due to the elasticity of the packing 7, and the stopper 5a is engaged by the protrusion or the groove 41 and the groove or the protrusion 51. It doesn't move easily. Therefore,
Even if the operating portion 5c is touched by fingers or the entire container is violently shaken, the horizontal protruding portion 40 and the stopper portion 5a do not shift in position, and the sealed and locked state can be reliably maintained.

[0021]

According to claim 1 of the present invention described above, the cosmetic drum A is sealed even if the lid 2 is left open unless the slider 5 for locking the inner lid is moved.
Therefore, reliable airtightness can be realized. Moreover, it has an excellent effect that the structure is simple, the external shape can be a simple one which is not different from a normal one, and a large mirror surface which can be easily visually recognized can be provided on the inner surface of the lid. According to the second aspect, since the operation portion 5a has a length reaching the lid locking portion 101 at the front of the main body when the lock is released, the lid 2 can be closed unless the inner lid 4 is in the locked state. Therefore, it is possible to obtain an excellent effect that it is possible to instantly confirm whether or not the airtightness is maintained and avoid forgetting to lock. According to the third aspect, it is possible to reliably maintain the sealed / locked state of the inner lid 4, and it is possible to obtain an excellent effect that the completion of the locking and the release of the locking can be sensed by the feel of the hand.
