Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a powder container for storing white powder, sky pollen, and other powders.

<Prior art> Containers for white powder, sky pollen, and other powders include: (1) The powder is stored in a container body made of cardboard, the top opening of the container is sealed with paper or other film-like sealant, and a lid is fitted. (2) As shown in Fig. 3, the powder is stored in the lower half of the container body A, which is slightly deeper, the bottom hole is sealed with sealant C, and the remaining edge C' of the seal is cut off. There was a structure in which the lid B was fitted into the container body A, and the outer lid was fitted over it. Incidentally, B' is attached to the rim of the container by the rim. The structure is such that a puff or other applicator is supported on the inner lid B.

<Problems to be solved by the invention> In configuration (1) of the prior art described above, fine powder scatters from the wide opening when sealing, and the powder adheres to the outer periphery of the container, making it difficult to adhere the seal. The container requires waterproofing. In addition, in both configurations (1) and (2) above, positioning is required in order to reliably seal the opening of the container with the sealing material, regardless of whether the cross-sectional shape of the container is circular or non-circular, and means and devices for this are required. In addition, the process of cutting off the remaining end portion C' of the sealing material along the shape of the opening is increased, resulting in an increase in cost. Also, the user required tools to open the seal.

Also, since powdered cosmetics are enclosed, when opening the lid,
When the seal ruptured, powder was often scattered due to the pressure difference, contaminating the container and surrounding area.

<Means for Solving the Problems> The present invention provides a powder container having a sealing structure that eliminates the need for a sealant, which is the biggest problem in the above-mentioned conventional technology, and prevents powder from scattering when the lid is opened. The container body is comprised of a container body for storing powder and a bottomed inner lid screwed into the container body, and an operating rib is provided on the upper surface of the inner lid so that it can be removed without any tools when the inner lid is in use. Further, a flexible flange is provided around the upper end of the inner lid to protrude outward, and the side wall of the container body is made thinner so as to gradually expand upwardly.

<Function> Powder is stored in the container body, and a bottomed inner lid is screwed and fitted to the container body to seal and store the powder in the container body, and when used, the inner lid is removed by rotating in the opposite direction.

Moreover, the flexible flange of the inner lid comes into close contact with the inner circumferential surface of the container body when the inner lid is fitted, thereby making the sealing of the powder into the container body more reliable. Furthermore, the side wall of the container main body, which is formed in a shape that gradually widens its inner circumference toward the top, functions to guide the inner lid during attachment and detachment, and to smoothly allow air to escape.

<Example> Fig. 1 shows an inner lid 2 screwed into a bottomed cylindrical container body 1 containing a powder 7, an inner mesh 4, a puff 6
FIG. 2 is a vertical cross-sectional view showing a state in which the container body 1 is housed and an outer lid 5 is fitted, and FIG. 2 is an enlarged exploded perspective view of the container body 1 and the inner lid 2.

The main point of the present invention is that the container body 1 integrally molded from synthetic resin and the inner lid 2 are connected by inner threads 1c and outer threads 2c provided on the inner and outer periphery of each of the side walls 1b and 2b. The lid 2 is configured to be detachable from the container body 1.

As shown in the drawings, the container body 1 has a flange 1a protruding from the outer periphery of the lower end, and the side wall 1b has an inner circumferential surface gradually thinned upward and an internal thread 1c cut in the middle. Powder 7 is accommodated below the internal thread 1c.

The inner lid 2 has a highly elastic flexible collar edge 2a on the outer periphery of the upper end.
An external screw 2c is cut into the side wall 2b, and an operating rib 2e is provided vertically along the diameter line on the upper surface of the bottom plate 2d.

The powder container of the present invention having the above configuration stores the powder 7 in the container body 1, and holds the powder 7 inside the container body 1 by pinching the operating rib 2e of the inner lid 2.
When the inner lid 2 is screwed and fitted with the outer screws 1c and 2c, the inner lid 2 is fixed to the container body, and the flexible flange 2a at the upper end of the inner lid 2 is fixed to the container body.
absorbs molding and dimensional errors of the container body, and the inner lid 2 comes into close contact with the inner circumferential surface of the container body, whose wall thickness gradually increases downward, so that the powder is hermetically stored. Tightening and loosening the screws allows air to communicate between the inside and outside. When in use, the inner lid 2 is removed by reversing this procedure, and powder is applied with a puff through the inner mesh 4.

In addition, when attaching and detaching the inner lid 2, a slit 3 is provided as shown in the figure for air escape and suction communication within the container body.
An appropriate number of them may be installed vertically in a sealed state up to the upper surface of the flange 2a.

<Effects of the invention> The powder container of the invention having the above-mentioned structure and operation eliminates the need for the conventional method of positioning and adhering the sealing material to the inner lid and container body, and cutting off the remaining ends. , the number of processing steps is reduced, and powder can be used by simply removing the inner lid without requiring an incision tool, and there is no scattering of powder. In addition, it is a practical idea that can be easily filled with powder and sealed without any auxiliary means.
