Description

The present invention relates to a cosmetic protection sheet provided between a cosmetic storage section and a lid section to protect cosmetics.

In cosmetic storage containers, a protective sheet is often used between the cosmetic storage section and the lid in order to protect the cosmetics during transportation and use (Patent Document 1). Particularly in the case of makeup cosmetics, in order to prevent the cosmetics from scattering or adhering to cosmetic tools, a protective sheet is used that can cover the cosmetics until the end of use. Regarding such protective sheets, various shapes have been studied to prevent them from being lost during use, and storage containers have also been studied (Patent Documents 2 and 3).

Generally, such protective sheets are in the form of a flat sheet, and the back side of the lid placed above the cosmetics is also formed in a flat plate shape. In some cases, they adhered to each other and were difficult to peel off. Particularly in the case of makeup cosmetic containers, there are many cases where a mirror is provided on the back of the lid, and if the protective sheet and mirror surface stick together and the air between them escapes, it becomes more difficult to remove the protective sheet. Become. Even if a gap is provided between the lid and the protective sheet, the protective sheet may come into close contact with the lid due to vibrations or static electricity during transportation.

Furthermore, if the back side of the lid is a mirror, if the protective sheet remains attached to the mirror, it will become difficult to see the mirror. In this regard, Patent Documents 2 and 3 disclose products having a knob for holding the protective sheet when peeling it off, but it is not desirable to provide such a knob from the viewpoint of product aesthetics. Therefore, conventionally, it was necessary to insert a thin plate-like object between the back of the lid and the protective sheet to peel it off.

Furthermore, if the protective sheet is stuck to the back of the lid when the lid is opened, the cosmetic will be exposed and you may accidentally touch the surface of the cosmetic. It has been desired that the protective sheet reliably cover the surface of the cosmetic.

EMBODIMENT OF THE INVENTION Hereinafter, embodiments of the protective sheet for cosmetics of the present invention will be specifically described based on the drawings. Note that the present invention is not limited to these embodiments in any way.

As shown in FIG. 4, the protective sheet 1 of the present invention is designed to cover the surface of the cosmetic in the storage section 4 in a cosmetic container equipped with a lid 3 that seals the upper opening of the container body 2. Placed. In the cosmetic container of this embodiment, an annular convex portion 42 that protrudes upward is formed on the opening edge 41 of the storage portion 4 . Moreover, although the lid part 3 of the cosmetic container of this embodiment is provided with a mirror 5 on the back side thereof, such a mirror 5 may not be provided.

As shown in FIG. 1, the protective sheet 1 of the present invention has a circular shape in a plan view, and has a flat portion 11 formed in a flat plate and a peripheral edge of the flat portion 11 that bulges upward from the flat portion 11. A rim portion 12 is provided. Although the shape is circular in this embodiment, the shape is not limited to a circle, and may be any other shape such as an oval, square, or rectangle. may be formed into a flat plate shape. Further, the method for forming the rim portion 12 is not particularly limited, but may be formed by vacuum molding, for example. Moreover, when the rim part 12 is not provided, it can be formed by a method such as punching.

The protective sheet 1 is placed in the cosmetic container so that the rim portion 12 covers the annular convex portion 42 of the storage portion 4. By covering the annular convex portion 42 with the rim portion 12 in this way, it is possible to prevent the protective sheet 1 from slipping sideways or falling when the lid portion 3 is opened.

When the lid part 3 is closed, a gap is created between the flat part 11 and the mirror 5, so that the two do not come into contact with each other, and the rim part 12 usually comes into contact with the mirror. By forming the rim part 12 in this way, it is possible to prevent the flat part 11 from coming into close contact with the mirror, but if for some reason the air in the closed space surrounded by the rim part 12 is forced out, Negative pressure may occur in the space, and a phenomenon may occur in which the rim portion 12 adheres closely to the mirror 5 and is difficult to peel off. Note that a gap may be provided in advance between the mirror 5 and the rim portion 12, but even in that case, the rim portion 12 may come into close contact with the mirror 5 due to vibrations during transportation, static electricity, etc. Confirmed.

In this regard, the rim portion 12 of this embodiment is further formed with a convex portion 13 that protrudes upward from its top surface. Therefore, as shown in FIG. 5, when the lid part 3 is closed, the top surface part 131 of the convex part 13 comes into contact with the mirror 5, and an additional gap is created between the mirror 5 and the mirror 5 by the height of the convex part 13. Air flows between the protective sheet 1 and the mirror 5 through the gap, and as a result, it is possible to effectively prevent the rim portion 12 from coming into close contact with the lid portion 3 and becoming difficult to remove. Note that the top surface portion 131 of the convex portion 13 does not always need to be in contact with the mirror 5, and the top surface portion 131 and the mirror 5 may be separated from each other when the lid portion 3 is closed.

The protrusions 13 in this embodiment are formed in three places at equal intervals with respect to the rim part 12, but the number of protrusions 13 is not limited to this and may be one, but it is preferable to have a plurality of protrusions. It is more preferable that the number of locations is greater than 1.

Although the convex portion 13 of this embodiment has a substantially rectangular cross-sectional shape and a planar view, the cross-sectional shape of the convex portion 13 is not limited to such a rectangle, and may be a square, a semicircle, a semiellipse, or a triangle. , trapezoid, or other polygons. Further, the shape in plan view is not limited to a substantially rectangular shape, but may be a square, circle, semicircle, ellipse, semiellipse, triangle, trapezoid, or other polygon. Furthermore, embossing may be performed by forming a large number of fine convex portions 13.

The height and width of the convex portion 13 are not particularly limited as long as they can prevent the lid portion 3 (mirror 5 in this embodiment) from coming into close contact with the rim portion 12; The width is preferably from 0.05 to 0.3 mm, preferably from 0.1 to 7 mm, and more preferably from 0.5 to 4 mm.

Further, instead of the convex portion 13, the concave portion 14 may be formed by recessing a part of the rim portion 12. The recess 14 is preferably formed so that the inner circumferential wall 121 and the outer circumferential wall 122 of the rim portion 12 communicate with each other, as shown in FIGS. 6 to 8. By forming the recess 14 in a part of the rim portion 12 in this way, the continuity of the annular rim portion 12 is interrupted by the recess 14 in the middle. That is, the rim portion 12 of this embodiment is divided by the recesses 14 and constitutes intermittently provided convex portions. With this configuration, air flows between the protective sheet 1 and the mirror 5 through the concave portion 14, thereby effectively preventing the protective sheet 1 from coming into close contact with the lid portion 3 and becoming difficult to peel off.

The number of recesses 14 is not particularly limited and may be one, but preferably a plurality of recesses, more preferably three or more. Further, the depth and width of the recess 14 are not particularly limited, but the depth is preferably 0.01 to 1 mm, more preferably 0.05 to 0.3 mm, and the width is 0.1 to 7 mm, more preferably 0.5 to 1 mm. A range of 4 mm is preferred.

Further, the convex portion is not limited to being formed on the rim portion 12 or formed by the rim portion 12 itself separated by the recess 14, but may be formed separately on the flat portion 11, for example. The convex portion formed on the flat portion 11 in this manner is formed so that its height protrudes higher than the height of the rim portion 12. In addition, when forming a convex part on the flat part 11, if the protective sheet 1 causes elastic deformation, the desired effect may not be obtained. Preferably, it is particularly preferably formed on the inner opening edge 41 of the annular convex portion 42 of the storage portion 4, which has no possibility of elastic deformation.

That is, the convex portion in the present invention prevents surface contact between the flat portion 11, which occupies most of the protective sheet 1, and the lid portion 3, and also ensures the inflow of air between the flat portion 11 and the lid portion 3. For this purpose, one convex portion may be sufficient, but it is preferable to provide multiple convex portions at predetermined intervals, and three or more convex portions may be provided at equal intervals along the periphery of the protective sheet 1. It is particularly preferable to arrange.

Furthermore, as shown in FIGS. 9 and 10, by providing a groove-shaped notch 15 on the top surface of the rim portion 12, air can flow into the flat portion 11. The cutout portion 15 is formed so as to communicate from the inner circumferential wall 121 side of the rim portion 12 to the outer circumferential wall 122 side. As shown in FIG. 10, the notch 15 in this embodiment has a V-shaped groove in cross-section, but it may also have a U-shape or a U-shape.

Although the cutout portion 15 in this embodiment is formed at only one location, it may be provided at a plurality of locations. The depth of the notch 15 is not particularly limited, but is preferably in the range of 0.01 to 1 mm, more preferably 0.05 to 0.3 mm, and the width is preferably in the range of 0.01 to 4 mm, more preferably 0.05 to 2 mm. A range is preferred.

Preferred materials for the protective sheet 1 of the present invention include polyethylene terephthalate, polypropylene, polystyrene, and the like.

The protective sheet 1 of the present invention is suitable for use not only in containers such as cosmetic compacts, but also as protective sheets that are discarded when opened, such as jar bottles for creams, solid eye shadows, etc., bottles for liquid substances, etc. I can do it.
