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 solid cosmetics, such as foundations, towels, and eye shadows, contain volatile components. However, conventional compact containers have poor airtightness and thus lose their volatile components. However, there is a problem that the material is liable to dry or shrink and crack. As countermeasures against this, conventionally, Japanese Utility Model Application Laid-Open No. 63-129512 (hereinafter referred to as Prior Art 1), Japanese Utility Model Application Laid-Open No. 3-119315 (hereinafter referred to as Prior Art 2), and Japanese Utility Model Application Laid-Open No. 4-31631 (hereinafter referred to as airtight compact container). Prior art 3) is known. Prior Art 1 pivotally attaches an outer lid that covers the entire surface of a body having a cosmetic storage section, and pivotally attaches an inner lid that can cover the cosmetic storage section to the outer lid. Attach a movable lid that is movably supported in the vertical direction via an elastic body, fix an elastic packing that can contact the outer edge of the cosmetic storage unit on the movable lid, and press the inner lid when closing the outer lid. The compression of the elastic body causes the movable lid to be pressed, and seals with elastic packing. Prior art 2 has a configuration in which a male screw-shaped ridge is provided on the outer periphery of an annular wall in which a cosmetic accommodating drum is fitted to a main body, while an annular wall is formed on an inner surface of a lid, and the male screw-shaped ridge is formed on the annular wall. A female screw ring internally provided with a female screw-shaped protrusion that can be screwed is rotatably held, and a ring packing that is in contact with a flange is attached to the cosmetic accommodating drum inside the lid on the inner diameter side of the short cylinder. The peripheral wall of the lid is not provided to expose a part of the female screw ring, and the female screw ring is screwed with the female screw-shaped ridge to achieve sealing. Prior Art 3 discloses a push-type lid opening / closing button having an engaging portion between a front portion of the inner frame and a front portion of the main body, wherein an inner frame having a fitting portion for a cosmetic drum is attached to a main body to which a lid is pivotally attached. On the other hand, on the inner surface of the lid, a packing that can come into contact with the flange of the cosmetic drum and a hook that engages with and disengages from the engaging portion are provided on the inner surface of the lid, and a window that allows the passage of the hook is provided in the middle frame. By providing a hole and closing the lid, the latch 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 against the cosmetic is released. Therefore, when the lid is opened at the time of use and the lid is left as it is, the cosmetic is removed. However, there is a problem that volatile components evaporate. Further, prior art 1 has a complicated structure using an inner lid, a movable lid, and an elastic body, which is expensive, and furthermore, the sealing force is affected 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 dimensional errors between the projections and the inner surface of the lid and aging of the elastic body. Furthermore, in this prior art 1, the mirror area cannot be made large, and when the mirror is made large, it comes into contact with the pressure receiving pedestal portion of the inner lid every time the mirror is opened and closed. There was a problem that the attached cosmetic was transferred to the mirror and the mirror was soiled.

Prior art 2 also has a special and very complicated structure, in which half of the female screw ring is exposed to the outside, which impairs the simplicity and smartness of the external appearance which is important as a cosmetic container, or causes a screw connection. There is a problem that a considerably large operation force is required to open and close the lid due to the method. Further, since the female screw ring occupies a half area of the inner surface of the lid, the area where the mirror can be provided is reduced, and there is a problem that it is difficult to visually recognize the makeup state.

The prior art 3 has a problem that the packing is fixed on the inner surface of the lid, so that the appearance is poor, and that if cosmetics or foreign matter adheres to the packing, a gap is formed to deteriorate the sealing property. As in the technology 2, since the packing occupies half the area 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 has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a simple structure which is simple in appearance while maintaining a simple appearance. Airtightness can be realized,
Another object of the present invention is to provide an airtight compact container capable of providing a large mirror surface easily visible on the inner surface of the lid.

[0007]

In order to achieve the above object, the present invention provides a main body having a lid pivotally mounted on a rear portion thereof, a middle frame having a hole for fitting a cosmetic drum and being attached to the main body. In a compact container of a type having an inner lid having a rear portion attached to a middle frame so as to be able to undulate and a packing attached to a lower portion capable of contacting a flange of the cosmetic drum, a horizontal protrusion is provided on the inner lid. A lower portion of the lever is provided, and a notch and a long hole are provided in the middle frame so as to allow the lever to be attached and detached.On the lower surface side of the middle frame, an operating portion projecting from the long hole and the An inner lid locking slider having a stopper that can be extended onto the horizontal protrusion of the lever is provided. The operating portion may have a length reaching above a lid locking portion at the front of the main body when the lock is released.
Further, the horizontal protrusion may have a ridge or a groove on the upper surface, and may have a groove or a ridge which can be engaged / disengaged on the upper surface of the stopper.

When the inner lid is turned down, the lever enters the inner frame through the notch in the inner frame, and when the moving operation section is operated in this state, the slider for locking the inner lid including this slides, and the stopper section is moved. Advances over the horizontal projection below the lever. For this reason, 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. The lid is not involved in the sealing and unsealing of the inner lid, and a gap can be set between the inner lid and the upper surface of the inner lid. And even if cosmetics adhere to the surface of the inner lid, the mirror will not be stained by this. Furthermore, since the inner lid lock mechanism uses a part of the inner lid and the slider for locking the inner lid that cooperates with the inner lid is arranged using the space below the inner frame, the compact and external appearance with the conventional inner lid It can be a simple and smart form whose shape does not change, and can have a simple structure and a low cost.

[0016]

Next, the operation of the embodiment and the state of use will be described. First, the assembly of the airtight compact container according to the present invention will be described.
The inner lid 4 is pivotally attached to the inner frame 3. And the base 1 of the main body 1
e, a slider 5 for locking the inner lid is arranged, and a guide lever 5b is provided.
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 part following the flange is fitted. At this time, the operation unit 5c projects upward from the long hole 30 of the middle frame 3. At the time of assembling the middle frame 3, the space between the divided surrounding walls 33, 33 is positioned by fitting into the protruding pieces 1a, 1a rising from the bottom of the main body 1, and the protruding pieces 1a, 1a and each of the divided An annular holding portion is defined by the surrounding walls 33, 33.
Therefore, by fitting the cosmetic drum A 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. The cosmetic drum A is stably held because the undercut portions 1a, 1a are engaged.

With this, the cosmetic container is completed. In this state, in order to hermetically seal the cosmetic filled in the cosmetic drum A, the inner cover 4 is closed and the operating portion 5c projecting from the inner frame 3 is locked. May be pressed to the side where is displayed. First, as the inner lid 4 is turned down, the front end lever 4c passes through the notch 31 of the inner frame 3, and the packing 7 on the lower surface of the inner lid 4 is
And the horizontal protrusion 40 at the lower part of the lever is located in the recessed seat 11 of the main body 1. This state is shown in FIG.
3A, the lower surface of the horizontal projection 40 is not in contact with the bottom of the recessed seat 11, and the upper surface is appropriately floating above the upper surface level of the recessed seat 11. When the operating portion 5c is pressed in this state, the guide lever 5b moves along the slot 10, so that the stopper portion 5a is formed on the upper surface of the base 1e and the concave groove 3 of the middle frame 3.
5 is stably moved while being in sliding contact with 5. As a result, the stopper 5a reaches the horizontal protrusion 40 of the lever 4c and presses it downward. As a result, the inner lid 4 is pulled downward through the lever 4c, so that the packing 7 is compressed and comes into close contact with the flange a of the cosmetic drum A.
A reliable sealing state is formed as shown in FIG. 5B and FIG. 5B. In this state, even if an attempt is made to lift the handle 4b of the inner lid 4, the inner lid 4 cannot be opened because the stopper 5a is located on the horizontal projection 40 of the lever 4c. Moreover, since the locked state of the inner lid 4 is separated from the opening and closing of the lid 2, even if the lid 2 is inadvertently left open, the interior of the cosmetic drum A is kept airtight, so that the The volatiles of the feed do not evaporate. Therefore, stable quality can be maintained for a long time.

When using the cosmetic, the operation section 5c may be moved again to the OPEN display position. In this case, the stopper 5a and the guide lever 5b are retracted, the engagement between the stopper 5a and the horizontal protrusion 40 of the lever 4c is released, and the lock is released.
By pinching and lifting b, the inner lid 4 is unfolded, and the exposed cosmetic can be applied using the applicator B to perform makeup. According to the present invention, the mirror 2b can have a large area (the inner lid 4 is not pressed by the pressing of the lid 2 or the packing is not provided on the inner surface of the lid). The desired clean makeup can be applied by fully using 2b. Also, when removing the cosmetics drum A from the holding part to replace it, the notch 31
This can be easily performed because the flange a can be lifted by inserting a fingertip into the flange. That is, the notch 31 can be shared as a replacement operation section for the cosmetic drum A, and it is not necessary to provide a separate dent or notch as in the related art.

In the second embodiment, the operation unit 5c is
When moving to the display position of EN, the end of the operation unit 5c extends beyond the end of the middle frame 3 as shown in FIGS.
Is located above the hook 101. In this state, the lid 2
The hook 201 comes into contact with the operation unit 5c even if the user tries to close the hook, so that the engagement between the hook 201 and the hook 101 is prevented. Therefore, forgetting to lock the inner lid 4 can be reliably avoided, and the lid 2 is always kept airtight and in a safe state.
Can be closed.

In the case where a protrusion or a groove 41 is provided on the upper surface of the horizontal protrusion 40 and a groove or a protrusion 51 is provided on the upper surface of the stopper 5a as shown in FIG.
a during movement of the ridge or groove 41 and the groove or ridge 51
Is engaged with the snap, the feeling is transmitted to the hand, and it is possible to reliably determine that the lock state has been attained. Further, at the time of locking, the horizontal protrusion 40 and the stopper 5a come into close contact with each other due to the reaction force of the elasticity of the packing 7, and the protrusion 5 or the groove 41 engages with the groove 5 or the protrusion 51 to form the stopper 5a. It doesn't move randomly. Therefore,
Even when the operator touches the operation part 5c or violently shakes the entire container, the horizontal protruding part 40 and the stopper part 5a are not displaced, and the sealed and locked state can be reliably maintained.

[0021]

According to the first aspect of the present invention described above, the cosmetic drum A is sealed as long as the inner lid locking slider 5 is not moved even if the lid 2 is kept open.
Therefore, reliable airtightness can be realized. In addition, an excellent effect is obtained in that the structure is simple, the external shape can be made simple, which is not different from a normal one, and a large mirror surface which can be easily recognized can be provided on the inner surface of the lid. According to the second aspect, since the operating portion 5a has a length reaching the lid locking portion 101 at the front of the main body at the time of unlocking, the lid 2 can be closed unless the inner lid 4 is locked. Therefore, it is possible to instantly confirm whether or not the airtight state is maintained, and to obtain an excellent effect that it is possible to avoid forgetting to lock. According to the third aspect, it is possible to obtain an excellent effect that the seal / lock state of the inner lid 4 can be surely maintained, and the completion of the lock and the unlock can be felt by the touch of the hand.
