Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a compact housing cosmetics such as foundations and eye shadows, and intends to improve the hermeticity of the compact.
[0002]
[Prior art]
Since volatilization of cosmetics such as foundations and eye shadows that contain volatile components is inevitable, compact materials that contain them are used with high airtightness.
[0003]
Conventionally, this type of compact has a compact airtightness by placing an elastic packing on a compact lid and allowing the packing to be sandwiched between the lid and the compact body when the lid is closed. I was trying to increase.
[0004]
By the way, in such a compact, since the lid body is normally held on the main body portion so as to be swingable via a pivot pin, there is a backlash between the lid body and the main body portion, and the packing is not closed when the lid body is closed. In some cases, the inside of the compact cannot be maintained in an airtight state because it may be sandwiched with the main body portion.
[0005]
In order to solve such problems, packing is slidably incorporated in the inner surface of the compact lid, and when the lid is closed, the packing is slid and fitted into the compact recess to maintain airtightness. A compact container has been proposed (see, for example, Patent Document 1).
[0006]
[Patent Document 1]
No. 7-10657.
[0007]
However, the compact disclosed in the above publication cannot cope with the positional displacement in the left-right direction between the recess and the packing because the packing slides only in the front-rear direction of the compact. There was also concern that the seal would be incomplete due to such reasons, and there was still room for improvement.
[0008]
[Problems to be solved by the invention]
The subject of this invention exists in the place which proposes the highly airtight compact which can prevent volatilization of the cosmetics accommodated compactly for a long period of time.
[0009]
[Means for Solving the Problems]
The present invention relates to a container main body provided with a drum filled with cosmetics, a lid that is swingably held by the container main body, and at least one of the container main body and the lid, and the inside of the drum is airtight. And a sealing member that holds the
An inner lid that holds the inside of the lid in an airtight state in cooperation with the seal member in the vertical or radial direction with respect to the drum on the rear surface of the lid, and the inner lid can be slid along the rear surface of the lid A plurality of positioning members that maintain the relative position with respect to the drum at all times by applying an elastic force toward the center of the inner lid and keeping the relative position with respect to the drum at all times.
The plurality of positioning member comprises a arcuate elastic body made in the arm-like elastic body or both ends supported to be cantilevered a hermetic compact, characterized in that.
[0011]
Rubber or elastomer can be applied to the seal member.
[0012]
Between the lid and the inner lid, the inner lid is pushed in a direction away from the lid, and the inner lid is cushioned against an external force toward the back surface of the lid and an external force along the back surface of the lid. It is desirable to dispose an elastic member that imparts properties.
[0013]
For the elastic member, rubber or elastomer can be used.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0015]
1 to 5 show the embodiment of the present invention as a parallel type compact in which cosmetics and puff recesses are arranged side by side, and FIG. 1 is a cross-sectional view of the front, FIG. FIG. 3 is a view showing the plane, and FIGS. 4 and 5 are views showing the side surface in cross section.
[0016]
1 to 5, 1 is a container body, 2 is a drum filled with cosmetics, 3 is an inner frame disposed in the container body 1, and the inner frame 3 is detachable from the container body 1. A recess 3b for storing an opening 3a and a puff or other applicator is formed.
[0017]
Reference numeral 4 denotes a lid body that is swingably held by the container body 1 via a pivot pin p, 5 is a slide hook that is provided on the container body 1 and locks the lid body 4 to the container body 1, and 6 is a lid. Mirror fixed to the back surface of the body 4, 7 is an inner lid disposed on the back surface of the lid body 4, and 8 is an integral unit provided on the lid body 4 to prevent the inner lid 7 from falling off the lid body 4. It is a piece.
[0018]
The inner lid 7 has a seal member 7a in contact with the edge 2a of the drum 2 on the lower surface thereof, and the drum 2 is adapted to be held in an airtight state by being fitted to the inner lid 7.
[0019]
Furthermore, 9 is a positioning member that elastically holds the inner lid 7 so as to be slidable in the entire circumferential direction on the back surface of the lid body 4, and maintains a relative position of the inner lid 7 with respect to the drum 2 at all times. Sometimes it is an elastic body for slightly lifting the lid 4.
[0020]
The positioning member 9 can be provided on the back surface of the inner lid 7. Here, three arm-shaped elastic bodies (springs) that are cantilevered with one end 9 a integrally connected to the inner lid 7 are provided. This is shown as an example.
[0021]
FIGS. 6A and 6B show the back surface and cross section of the inner lid 7.
[0022]
The other end 9 b of the positioning member 9 is in contact with the annular wall 4 a of the lid 4, and an elastic force directed toward the center O (see FIG. 3) acts on the inner lid 7 to tilt the lid 4. Regardless of the degree change, it is positioned at a certain place.
[0023]
As a result, the relative position of the inner lid 7 with respect to the drum 2 is always kept constant. When the lid 4 is closed, the seal member 7a uniformly contacts the entire area of the edge 2a of the drum 2 and the inside thereof is airtight. Maintained.
[0024]
FIGS. 7A and 7B show another example in which an arch-like elastic body integrated with the inner lid 7 is provided as the positioning member 9, and such a positioning member 9 is shown in FIG. Even if it is installed on the lid 4 as shown in (b), the same effects as those shown in FIGS. In the above-described two embodiments, the case where the positioning member 9 is provided integrally with the inner lid 7 is shown as an example. They may be connected to contact the inner wall of the inner lid 7.
[0025]
FIG. 9 shows a main part of still another embodiment of the present invention. In the figure, 11 is a seal member provided on the drum 2 by insert molding or adhesion instead of the seal member 7 a disposed on the lower surface of the inner lid 7, and 12 is an elastic member provided between the inner lid 7 and the lid body 4. It is. In this example, as the arrangement location of the seal member 11 is changed from the inner lid 7 to the drum 2, two ridges are provided around the contact portion of the seal member 11 of the inner lid 7.
[0026]
The elastic member 12 has a substantially 8-shaped shape with a narrowed central portion in the vertical direction, and a plurality of elastic members 12 are provided on the back surface of the inner lid 7 or at equal intervals around the circumference. Extruding in a direction away from the body 4 and imparting cushioning to the inner lid 7 against an external force directed to the back side of the lid body 4, thereby bringing the inner lid 7 into strong contact with the seal member 11 Thus, the airtight state can be further enhanced.
[0027]
Further, by fixing the end portions 12a and 12b of the elastic member 12 to the inner lid 7 and the lid body 4 by adhesion, fusion or engagement, respectively, the elastic member 12 keeps the inner lid 7 constant by its elastic force. The position of the inner lid 7 can be strengthened together with the positioning member 9.
[0028]
The seal members 7a and 11 and the elastic member 12 are made of rubber or elastomer, but the present invention is not limited to this, and the material thereof can be changed as appropriate. Furthermore, the location of the seal member is not limited to the case where the seal member is arranged on the lower surface of the inner lid 7 or one of the drums 2 but can be arranged on both of them.
[0029]
Moreover, although the parallel type compact was shown as an example in the above FIGS. 1 to 5 as an embodiment of the present invention, the present invention can also be applied to a series type compact as shown in FIGS. Needless to say.
[0030]
【The invention's effect】
According to the present invention, when the lid is closed, the airtight holding inner lid always moves to the center thereof, and the seal member is uniformly fitted around the drum, so that the inside thereof is always kept airtight.
