Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a compact container for storing cosmetics, and particularly to an airtight compact container that requires airtightness.

[Prior art]

In the conventional airtight compact container inner dish 14, generally, as shown in the twelfth illustration, a flat flange portion 15 is provided on the periphery of the dish portion,
An endless ridge 17 of a packing 16 made of an elastic material was brought into contact with the flange 15 to maintain airtightness.

[Problems to be solved by the device]

However, with such a structure, it is technically difficult to process the flange portion 15 into a sufficiently flat shape. Therefore, if the outer peripheral edge of the flange portion 15 has a large flash, this flash hits the packing 16 and the ridge portion 17 In some cases, there was a portion that was not in contact with the portion 15. Further, if the degree of bending of the flange portion 15 is too large or too small or is deformed, there may be a case where the ridge portion 17 does not reach the flange portion 15. For this reason, the contact between the ridge 17 of the packing 16 and the flange 15 is intermittent, and sufficient airtightness cannot be obtained. In order to deal with such a situation, as shown in FIG. 13, there has been a case in which a second ridge portion 18 is provided along the bending line of the dish portion and the flange portion 15 to thereby ensure airtightness. However, even in such a conventional example, when the inner plate 14 has a shape other than a square or a circular shape, the distance from the center of the inner plate 14 to the outer peripheral edge of the flange portion 15 is larger than that in the case of a circular shape. The flatness error of 15 was large, and there was a drawback that defective contact was likely to occur due to flash and deformation. Since the consumer of the compact container is a woman, it is necessary to prepare the inner plates 14 of various shapes, so that such a drawback cannot be overlooked. However, since it is difficult to deal with the contact failure by aligning the packing 16, it has not been possible to obtain sufficient airtightness in the related art. In the container as shown in FIG. 12 and FIG. 13, in order to avoid the above-mentioned abutting failure, the ridge 17 of the packing 16 is attached to the flange 15.
When the second ridge portion 18 and the second ridge portion 18 are strongly brought into contact with each other, the packing 16 is elastically deformed, so that the ridge portion 17 and the second ridge portion 18 are formed as shown in FIGS.
As shown in the figure, since it slips off, a gap may be partially formed on the contact surface, and sufficient airtightness could not be obtained. Further, there is a drawback that the packing 16 itself is worn out quickly. As a result, conventionally, it has not been possible to deal with cosmetics having higher volatility. An object of the present invention is to solve the above-mentioned drawbacks and to provide an airtight compact container in which the packing is sufficiently brought into contact with the flange portion of the inner plate and the airtightness of the container is fully ensured. It is also an object to provide an airtight compact container whose ensuring of airtightness is not influenced by the shape of the inner plate.

【Example】

Next, an airtight compact container according to the present invention will be described based on an embodiment shown in the drawings. The container body 1 includes an upper lid 2 and a lower lid 3. One end of the upper lid 2 is pivotally attached to the lower lid 3 by a pin 4, and the other end of the upper lid 2 is openably and closably fitted to the lower lid 3. An inner plate 5 made of a hard material such as aluminum, brass, or iron is placed on the lower lid 3. The inner plate 5 is composed of a plate portion 6 for storing cosmetics and a flange portion 7 continuous with the upper end of the plate portion 6. The flange portion 7 includes
An endless groove 8 is provided along a line surrounding the plate portion 6. Reference numeral 9 is an inner frame fixed to the lower lid 3. The plan view shape of the plate portion 6 and the flange portion 7 is arbitrary, such as a circle or a square. A packing 10 made of a soft material such as NBR rubber or silicone rubber is fixed to the upper lid 2, and a three-dimensional protrusion 12 that abuts the groove 8 is provided on a peripheral edge portion 11 of the packing 10. The degree of abutment includes the degree of abutment to the pressure contact, but it is preferable that the pressure contact be strong. If the cross-sectional shape of the groove 8 is three-dimensionally recessed, it is curved,
It may be bent or flat and is arbitrary. 1 shows the case of a semicircular cross section, FIG. 3 shows the case of a triangular cross section, and FIG. 4 shows the case of a square cross section. Although the recessed position of the recessed groove 8 is arbitrary, the center portion is more preferable than the outer peripheral edge and the bent edge of the flange portion 7 as illustrated. The number of the concave grooves 8 is arbitrary. 1 to 4 show a single case, and FIG. 5 shows a case where a plurality of concave grooves 8a are provided below the concave groove 8
The figure shows the case where a plurality of rows of concave grooves 8 are provided. The degree of depression of the groove 8 is appropriately designed depending on the material of the packing 10 and the like. Reference numeral 13 is a frame body for fixing the packing 10 to the upper lid 2. G is a gap between the flange portion 7 and the peripheral portion 11. The same function can be achieved by forming the entire flange portion 7 three-dimensionally instead of the groove 8.
FIG. 7 shows another embodiment in which the flange portion 7 has a concave arcuate section 7a, and FIG. 8 shows another embodiment in which the flange section 7 has a concave arcuate section 7b. In either case, as shown in FIG. 9, it is possible to further provide a groove 8b in the flange portion 7a formed by being recessed. The number of the recessed grooves 8b may be single or plural, and may be provided in a plurality of rows. The airtight compact container according to the present invention comprises an upper lid 2 and a lower lid 3.
It can also be applied to a container having an inner lid (not shown) between and. Further, it can be applied to a slide type container instead of the open / close type as shown in the drawing. Further, the plan view shape of the concave groove 8 is provided along the shape of the dish portion 6 such that the dish portion 6 has a circular shape when the dish portion 6 is circular, and a square shape when the dish portion 6 has a square shape. It is also possible to provide without. In the latter case, the design effect is further improved, which is advantageous for a compact container whose customer is a woman.

[Action]

When the lid of the airtight compact container according to the present invention is closed, the packing 10 is pressed by the upper lid 2, so that the projection 12 of the peripheral edge 11 of the packing 10 is three-dimensionally embedded in the groove 8 of the flange 7. Therefore, even if there is a flash 19 on the outer peripheral edge of the flange portion 7, this is absorbed, and the flange portion 7 is also absorbed.
This error amount is absorbed even when the degree of flexion is excessively large or small and is deformed (see FIGS. 10 and 11). Furthermore, since the ridges 12 bite into the groove 8 three-dimensionally,
Even if the flange portion 7 is formed in a rectangular shape in a plan view and the flatness thereof is rough, the error amount is absorbed without being affected by the error. Since the recessed groove 8 is three-dimensionally recessed, the protrusion 12 of the packing peripheral portion 11 always contacts at any part. Moreover, this contact is made by pressing the projection 12 of the packing peripheral edge portion 11 into the recessed groove 8 which is three-dimensionally recessed, so that it is always pressed at a constant pressure, and the stronger the contact, the stronger the contact. The packing is deformed to increase the contact area between the concave groove 8 and the protrusion 12, and the adhesion is improved. Therefore, in the airtight compact container according to the present invention, there is no room for contact failure between the packing 10 and the flange portion 7, and the airtightness of the container is sufficiently ensured. The above-mentioned reason is the same when the flange portion 7 is formed in a concave arc shape or a concave corner shape in place of the concave groove 8. In addition, in the airtight compact container according to the present invention,
Since the groove portion 8 is provided in the flange portion 7, when scraping off the cosmetic material with the puff, the excess portion of the scraped cosmetic material falls into the groove groove 8 and does not stain other parts of the container. Have a profit

[Effect of device]

As described above, according to the airtight compact container of the present invention, the inner plate is built in the container body including the upper lid and the lower lid,
In an airtight compact container having a sealed structure through a packing abutting on a flange portion of the inner plate, an endless groove is provided on the flange portion along a line surrounding the plate portion of the inner plate, Since the packing of the portion corresponding to the groove is formed on the protrusion and is detachably abutted on the groove, the airtightness of the container can be fully ensured. In addition, the airtightness of the container is ensured regardless of the shape of the inner plate. As a result, it is possible to deal with cosmetics having higher volatility.
