Description

  The present invention relates to a compact used for housing cosmetics, and is intended to securely hold a drum as a refill container filled with cosmetics in a compact main body portion and realize simple attachment / detachment. Is.

The compact generally has an internal space that can store cosmetics such as eye shadows, eyeliners, foundations, etc. together with applicators such as puffs, especially for cosmetics from the viewpoint of realizing continuous use of the container body. A detachable cosmetic filling drum adapted to the internal space is incorporated so that only new cosmetic can be replaced after it is used up (see, for example, Patent Document 1).
Utility Model Registration No. 2517071

  Normally, this type of cosmetic filling drum is fixedly held by undercut fitting with a plurality of legs provided so as to project directly or vertically on the main body of the compact container. It is normal to do so and it can be easily replaced.

  By the way, in a drum having a square planar shape having a corner portion formed by a constant R or a drum having a round planar shape, and having a structure in which the drum is supported by a corner portion or a curved surface, However, it is usual to adopt a cross-sectional shape with a radius or curvature equivalent to that of the corner or curved surface of the drum. However, the leg portion having such a shape itself is not easily elastically deformed (the width dimension is There is a problem that a large force is required to attach and detach the drum, and when the impact force is applied compactly due to inadvertent dropping, the impact is transmitted directly to the drum through the legs. As a result, the drum could easily fall out of the internal space.

  An object of the present invention is to propose a novel compact capable of solving the conventional problems as described above.

The present invention is a compact comprising a drum for filling and holding cosmetics, and a container body that has an openable / closable lid and detachably accommodates the drum directly or through an inner frame.
Provided with a plurality of elastic pieces connected to any one of the container main body and the inner frame and in contact with the side wall of the drum so as to hold and support the drum.
The elastic piece located at the corner portion or the curved portion of the drum has an R shape along the corner portion or the curved portion, and has a fitting rib or fitting groove portion that fits undercut into a groove portion or a protrusion provided on the drum. It is compact characterized by having.

  In the compact having the above configuration, it is preferable that at least one of the elastic pieces having the fitting rib or the fitting groove is provided with an operation lever for forcibly moving the elastic piece backward to release the undercut fitting. .

  The drum may have a substantially square planar shape or a round planar shape.

  The elastic piece that supports both ends is easy to bend, so even if the length is extended to ensure a stable holding posture of the drum, the drum can be attached and detached with a small force, and the drum is supported. The bending of the elastic piece at the end makes it possible to effectively absorb the impact force and the drum does not easily fall off.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) to 1 (c), 2 (a), 2 (b) and 3 show a compact embodiment according to the present invention, and FIG. 1 (a) shows a state in which a lid is removed. FIG. 1B is a diagram showing a cross section of the front surface with the lid attached, and FIG. 1C is a diagram showing a cross section of the side surface with the lid attached. 2 (a) and 2 (b) are an enlarged view (plan) and a cross-sectional view of the main part of FIG. 1 (a), and FIG. 3 is a cross-sectional view of the main part of FIG. 1 (b).

  1-3, reference numeral 1 is a container body, 2 is a lid body that is supported on the container body 1 through a pivot pin so as to be opened and closed, and 3 is an example having a substantially square planar shape for filling and holding cosmetics. It is the drum shown by.

  Reference numeral 4 denotes an elastic piece that is integrally connected to the inner frame of the container body 1 with both ends supported, and contacts the side wall portion of the drum 3. Of the elastic piece 4, the corner portion of the drum 3 (curved in the case of a round shape) Part) The elastic pieces (4a to 4d) located at 3a to 3d have an R shape along the corners 3a to 3d as shown in FIG. 4, and are under the groove 5 (see FIG. 2 (b)) of the drum 3. A fitting rib 6 for cutting and fitting is provided, and the elastic pieces (4e to 4h) located on the straight wall portion of the drum 3 can be supported by holding the drum 3 between the opposing elastic pieces. 5 has a flat surface that is in close contact with the wall, as shown in an external perspective view of FIG. 5, so that the drum 3 can be clamped and supported by sandwiching the drum 3 from the front and rear and the left and right. Reference numeral 7 denotes a packing disposed between the lower surface of the drum 3 and the upper surface of the container body 1, and the packing 7 has a function of absorbing an impact applied to the drum 3. The relationship between the elastic pieces (4a to 4d) and the corner portions 3a to 3d of the drum 3 is that the drum 3 can be held by contact only with the fitting rib 6 as shown in FIG. The drum 3 may be pressed and held between the fitting rib 6 and the inner wall surface of the elastic piece (4a to 4d).

  At least one of the elastic pieces 4 a to 4 d can be provided with an operation lever 8 that can be integrally formed with the elastic piece 4 as shown in FIG. 6, and an opening provided at the bottom of the container body 1. 2b, the undercut fitting can be released by moving the elastic piece 4 backward according to the arrow shown in FIG. 2 (b) (the drum 3 can be easily removed by releasing the undercut fitting in one place). it can).

  FIG. 7 is an external perspective view of a leg portion provided in a conventional compact, particularly when the leg portion has a cross-sectional shape along a corner portion or a curved portion of the drum. Therefore, deformation with the fixed end as a fulcrum is difficult, and this is particularly noticeable when the width w of the leg is increased in order to increase the support strength of the drum. There is a disadvantage that the impact force at that time is directly transmitted through the leg portion when it is applied, and there is a disadvantage that it easily falls off the leg portion.

  In the compact according to the present invention, the elastic piece (4a to 4d) is supported at both ends, but can be bent based on the connecting part (elastically connected part), so that the drum 3 can be reliably and stably provided. Even if the length L (see FIG. 4) of the elastic piece is increased so as to support it, the fitting strength at the time of undercut fitting does not change, and the drum can be easily attached and detached. Moreover, since the elastic pieces (4a to 4d) located at the corner portions 3a to 3d have an R shape along the corner portions 3a to 3d, even if the length of the fitting rib 6 is increased, elastic deformation is caused. It becomes possible to secure an allowable gap.

  Further, when an impact is applied with the undercut fit, the impact force is effectively absorbed by the bending of the elastic piece 4.

  In the embodiment of the present invention, the example in which the elastic ribs (4a to 4d) are provided with the fitting ribs 8 to perform the undercut fitting has been described. However, the corners 3a to 3d of the drum 3 are provided with rib-shaped protrusions. In this case, the elastic piece (4a to 4d) is provided with a fitting groove that fits the protrusion, and the fitting groove is undercut fitted to the rib-like protrusion to support the drum 3.

  In the above-described embodiment, the case where the elastic pieces (4a to 4d) are provided in the middle frame is shown. However, in the case where the container body 1 does not have the middle frame, it is directly provided on the container body 1. May be.

  The drum can be held in a stable posture, and a compact that does not easily fall off due to impact can be provided.
