Description

The present invention relates to a wide-mouthed container that can contain liquid or powdery contents and take them out little by little for use.

As a wide-mouthed container that stores powder-like contents and takes them out little by little for use, for example, a mesh frame that elastically moves up and down via elastic legs is provided in the opening of the container body, and the container body is used. There is known a powder container in which a puff is pressed against the mesh frame to gradually take out the inner cosmetic powder from above the opening (see Patent Document 1).

However, as described above, when the puff is pressed against the mesh frame to take out the cosmetic powder inside, an excessive force is applied to the mesh frame at the time of pressing, and the mesh frame tilts or the mesh comes off from the frame and breaks. There is a risk of

Therefore, as a method of elastically and stably supporting the mesh frame, a tubular body made of an elastic body such as a sponge is fitted into the container body, and the mesh frame is supported by the tubular elastic body. Some of these have been proposed (see Patent Documents 2 and 3).

For example, as shown in FIG. 4A, the cosmetic container of Patent Document 2 includes a container body 1 for accommodating the gel-like cosmetics 10, an elastic member 2 provided along the inner wall of the container body 1. It includes a mesh frame 4 to which a mesh 3 is attached, which is placed on the elastic member 2. Reference numeral 5 denotes an inner lid that covers the opening of the container body 1, and reference numeral 6 denotes a lid that covers the upper surface thereof.

According to this cosmetic container, the elastic member 2 that supports the mesh frame 4 has a cylindrical shape along the inner wall of the container body 1 as shown in FIG. 4B, and is placed on the elastic member 2. In order to elastically support the mesh frame 4, when the puff 7 is pressed downward from above the mesh 3 as shown in FIG. 4 (c), the container body 1 does not place much burden on the mesh 3. The gel-like cosmetic 10 inside can be impregnated into the puff 7 side.

As described above, the one in which the load on the mesh 3 is reduced by using the cylindrical elastic member 2 has an advantage that the mesh 3 is not easily damaged, but the mesh 3 is elastic depending on the pushing operation of the puff 7. The gel-like cosmetics are deeply immersed in the gel-like cosmetics 10 together with the member 2, and the gel-like cosmetics overflow on the eyes of the mesh 3, and the gel-like cosmetics more than necessary may stick to the pushed puff 7. In this case, the puff 7 must be applied to the opening edge of the container body 1 to drain the liquid, which is not easy to use. In addition, the opening edge of the container body 1 and its surroundings are easily soiled with gel-like cosmetics. Further, there is a problem that the puff 7 is easily caught or caught in the mesh 3 and is easily damaged over time. These problems are the same even when the content is in the form of powder or the like.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an excellent wide-mouthed container that can take out the contents little by little and evenly and is easy to use.

In order to achieve the above object, the present invention has a tubular body having a recess for accommodating the contents and a tubular shape fitted in the recess of the container body and having an outer peripheral surface along the inner wall surface of the recess. A wide-mouthed container including a closed-cell porous elastic body, an inner lid placed on the upper surface of the tubular porous elastic body, and a lid covering the upper surface of the container body, and has the tubular shape. The closed-cell porous elastic body is made ^{of a dry urethane sponge having an apparent density of 15 to 90 kg / m 3} , an elongation rate of 70% or more, and a cell number of 10 to 70 cells / 25 mm. an annular guide having, is composed of a substantially plate-like open-cell porous elastic body integrally attached to the upper surface of the annular guide, the lower surface of the annular guide is in contact with the upper surface of the closed cell porous elastic body The lower surface of the annular guide has an uneven surface due to a streak pattern or small protrusions, and the substantially plate-shaped open-cell porous elastic body has an apparent density of 20 to 50 kg / m ³ and an elongation rate. It is made of a dry urethane sponge with 80% or more and 10 to 70 cells / 25 mm, and the contents are taken out from the recess via the open cells of the substantially plate-shaped open cell porous elastic body. The first gist is the wide-mouthed container.

Further, in the present invention, in particular, in the inner lid, the outer peripheral shape of the substantially plate-shaped open-cell porous elastic body is set to be larger than the inner peripheral shape of the concave portion of the container body. the shall be the second aspect.

In the present invention, the term "substantially plate-like" means a strict plate-like shape, a plate-like shape having a portion having a partially different thickness, or a curved plate shape even if the thickness is the same. The purpose is to include things.

That is, in the wide-mouthed container of the present invention, a tubular closed-cell porous elastic body along the inner wall surface of the recess is fitted in the recess of the container body, and an inner lid is arranged in the opening of the recess. but has an annular guide having rigidity, a feature that is composed of a substantially plate-like open-cell porous elastic body integrally attached to the upper surface of the annular guide. Then, the contents are taken out from the recesses via the open cells of the substantially plate-shaped open-cell porous elastic body.

According to this configuration, the substantially plate-shaped open-cell porous elastic body itself is an elastic body having shape-retaining properties, and a large number of open-cells distributed inside the elastic body is a fluid liquid, powder, or the like. Since it serves as a path for the contents of the above, it is convenient to take out the contents little by little and evenly through the open cells.
Further, since the contents do not enter the inside of the tubular closed-cell porous elastic body, the contents between the cylindrical closed-cell porous elastic body and the inner wall surface of the recess are less likely to be contaminated, and the appearance is improved. It will be good.
Moreover, since the lower surface of the annular guide is an uneven surface due to a streak pattern or small protrusions, this surface is less likely to deviate from the tubular porous elastic body.

In particular, since the open-cell porous elastic body is made ^{of a dry urethane sponge having an apparent density of 20 to 50 kg / m 3} , an elongation rate of 80% or more, and a cell number of 10 to 70 cells / 25 mm. In particular, the contents can be taken out uniformly without excess or deficiency, which makes it easy to use.

Moreover, since the substantially plate-shaped open-cell porous elastic body is integrally attached to one side of the rigid annular guide, even if the open-cell porous elastic body is pushed deeply, the annular guide stays in the circumferential direction. The position of the tubular porous elastic body is lowered evenly while being pressed. Therefore, the open-cell porous elastic body does not tilt and falls into the recess, and can be used repeatedly and satisfactorily. Since a large amount of the contents can be contained in the open cells of the open-cell porous elastic body, even if the contents are pushed deeply, the contents are on the surface side of the open-cell porous elastic body like a conventional mesh. Does not overflow and accumulate, and more content than necessary does not stick to puffs or the like.

Further, even when the amount of the contents is reduced to a small amount at the bottom of the recess, the open-cell porous elastic body supported by the cylindrical porous elastic body is greatly elastically deformed to provide the contents. Since the object can be taken into the open cell, the content can be used up to the end without waste.

Even if such elastic deformation is repeated, the open-cell porous elastic body itself does not easily lose its shape and does not tear, and the upper surface of the cylindrical porous elastic body having cushioning properties. Combined with the fact that it is placed in, it can be used well for a long period of time. In terms of cost, it is more economical than the conventionally used mesh and has the advantages of high versatility.

Among the wide-mouthed containers of the present invention, in particular, in the inner lid, the outer peripheral shape of the substantially plate-shaped open-cell porous elastic body is set to be larger than the inner peripheral shape of the concave portion of the container body. Is that the peripheral edge of the substantially plate-shaped open-cell porous elastic body comes into contact with the inner wall surface of the concave portion of the container body in a pressed form, so that the posture of the open-cell porous elastic body in the concave portion is more stable. It will be the one that was done.

Next, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments.

FIG. 1 is an exploded perspective view showing an embodiment of the wide-mouthed container of the present invention. This wide-mouthed container is for storing a viscous liquid cosmetic 11 (see FIG. 2) such as a liquid foundation, and is a relatively short jar type container. A container body 13 having a recess 12 for accommodating the liquid cosmetics 11 and a tubular porous elastic body (hereinafter referred to as “cylindrical elastic body”) 14 fitted in the recess 12 are provided. There is. Further, a substantially disk-shaped inner lid 15 is arranged on the upper surface of the tubular elastic body 14 in the opening of the recess 12.

More specifically, the container body 13 is made of a substantially bottomed cylindrical injection-molded product, and the inside thereof is a recess 12 for accommodating the liquid cosmetics 11. Then, as shown in FIG. 2, on the peripheral wall 18 of the container body 13, a male screw portion 17 for screw engagement with the lid 16 is formed on the upper portion thereof. Further, in the lower portion of the male screw portion 17, an outer cylinder wall 19 is provided from the viewpoint of reinforcement and appearance of the container main body 13 to form a double wall.

A tubular elastic body 14 is fitted along the inner wall surface of the container body 13. The tubular elastic body 14 has a cylindrical wall with a thickness of 5 mm and is formed of foamed polyurethane in which closed cells are dispersed and formed. As shown in FIG. 2, the height of the tubular elastic body 14 is set to be higher than the liquid level of the liquid cosmetic 11 in a fully-filled state. Therefore, the liquid cosmetic 11 contained in the recess 12 is substantially housed in the hollow portion inside the tubular elastic body 14.

The inner lid 15 arranged on the upper surface of the tubular elastic body 14 has a rigid annular guide 15a as shown in FIG. 3 (a) which is a front view thereof and FIG. 3 (b) which is a bottom view thereof. , It is composed of a disk-shaped open cell porous elastic body (hereinafter referred to as "disk-shaped elastic body") 15b integrally attached to the upper surface thereof.

The annular guide 15a is a punched-molded product of a polypropylene sheet having a thickness of 1 mm, and a streak pattern S having very shallow irregularities is provided on the lower surface thereof, that is, the surface in contact with the upper surface of the tubular elastic body 14. This is such that the annular guide 15a, that is, the inner lid 15 is difficult to move on the upper surface of the tubular elastic body 14.

The disc-shaped elastic body 15b integrally attached to the upper surface of the annular guide 15a is a disc-shaped foamed polyurethane sheet (open cell type) having a thickness of 5 mm. The method of integrating the disc-shaped elastic body 15b and the annular guide 15a is not particularly limited, but for example, in addition to bonding using an adhesive, ultrasonic welding, vibration welding, laser welding, or the like may be used. Can be done. Further, the inner lid 15 may be obtained by insert molding in which the disc-shaped elastic body 15b is formed while the annular guide 15a is arranged in the mold.

Then, as shown in FIG. 2, a packing 20 for preventing liquid leakage is attached to the inner ceiling surface of the lid 16 that covers the upper surface of the container body 13 from above the inner lid 15. The packing 20 is a punched-molded product of a foamed polyethylene sheet having a thickness of 1 mm. When the lid 16 is screw-engaged with the container body 13 and tightened, the packing 20 comes into close contact with the upper end surface of the container body 13. , The liquidtightness is improved.

The wide-mouthed container can be used, for example, as follows. That is, first, the lid 16 is opened to expose the inner lid 15 arranged in the upper part of the opening of the container body 13. Then, the central side of the disc-shaped elastic body 15b of the inner lid 15 is pushed downward with a puff or the like, and the liquid cosmetic 11 in the recess 12 is taken into the open cells of the disc-shaped elastic body 15b. Then, this time, the disc-shaped elastic body 15b can be lightly tapped with a puff or the like to hold a required amount of the liquid cosmetic 11 on the puff or the like and used for makeup.

As described above, according to the wide-mouthed container, the disc-shaped elastic body 15b provided on the inner lid 15 is an elastic body having shape retention itself, and a large number of open bubbles distributed inside the elastic body 15b are formed. Since it serves as a path for the liquid cosmetics 11, the liquid cosmetics 11 can be taken out little by little and uniformly via the open cells.

Further, even if the amount of the liquid cosmetic 11 is reduced and the disc-shaped elastic body 15b pushed into the recess 12 does not sufficiently reach the liquid cosmetic 11 in the recess 12, the pushing operation and the releasing operation are performed. Due to the elastic deformation of the disc-shaped elastic body 15b, the liquid cosmetics 11 are taken in as if they are sucked into the open cells, so that the liquid cosmetics 11 can be used up to the end without waste.

Even if such elastic deformation is repeated, the disc-shaped elastic body 15b is guided by the annular guide 15a and is placed on the cushioning tubular elastic body 14 in a stable state. , It does not lose its shape or tear, and can be used repeatedly and well. In terms of cost, it has the advantages of being more economical and more versatile than the conventionally used mesh [see FIG. 4 (a)].

In the present invention, the tubular elastic body 14 is fitted into the container body 13 has an outer peripheral surface along the inner wall surface of the recess 12 of the container body 13, Ru closed cell porous elastic body der. That is, since a closed cell porous elastic body, the container body 13, the liquid cosmetic 11 there is no fear that leak around the recess 12 through the cylindrical elastic body 14, Ru der having good freely have used.

As the material of such a tubular elastic body 14, a material that does not deteriorate even when it comes into contact with the contents such as liquid cosmetic 11 and does not lose its elasticity even when it is repeatedly compressed is preferably used. Specifically, dry urethane sponge (polyester type) using polyurethane as the main raw material, wet urethane sponge (polyester type, polyether type) also using polyurethane as the main raw material, acrylonitrile butadiene rubber (NBR) latex, natural rubber (NR). ) Latex, styrene-butadiene rubber (SBR) latex, isoprene rubber (IR) latex, chloroprene rubber (CR) latex and other latex-based latex sponges and the like can be mentioned. In the present invention, selectability of the cell size, in terms of chemical resistance, dry urethane sponge Ru is used.

Among the above-mentioned dry urethane sponges, ^{those having the characteristics of an apparent density of 15 to 90 kg / m 3} , an elongation rate of 70% or more, and a number of cells of 10 to 70/25 mm are particularly excellent cushions. includes sex, Ru used in the present invention. Incidentally, as commercially available products having such characteristics, color foam EMM (manufactured by Inoac Corporation), maltoprene SF (manufactured by Inoac Corporation), and the like can be mentioned.

Further, in the present invention, the annular guide 15a of the inner lid 15 does not have to be a stamped product of polypropylene as in the above example, and various resin molded products can be used. However, it is desirable that the resin material of the resin molded product does not deteriorate or deteriorate in contact with the liquid cosmetic 11 or the like which is the content. Further, the present invention is not limited to resin molded products, and is not particularly limited as long as it has a certain rigidity. For example, waterproof thick paper, stainless steel, glass, various ceramic molded products, etc. are used. May be good.

The rigidity of the annular guide 15a is set to an appropriate rigidity according to the material of the disc-shaped elastic body 15b attached to the annular guide 15a, the material of the tubular elastic body 14 on which the inner lid 15 is placed, and the like. .. That is, even if the disc-shaped elastic body 15b is repeatedly pressed downward to expand and contract during use, the annular guide 15a is rigid enough to maintain the annular shape without bending or breaking. Is desirable.

Further, in the above example, a streak pattern S [see FIG. 3B] having very shallow irregularities is provided on the lower surface of the annular guide 15a, and friction between this surface and the upper surface of the tubular elastic body 14 is provided. The coefficient was increased to prevent the inner lid 15 from slipping off the upper surface of the tubular elastic body 14, but for the same purpose, even if small protrusions are provided on the lower surface of the annular guide 15a in an appropriate arrangement instead of a streak pattern. not good.

On the other hand, the disc-shaped elastic body 15b attached to the annular guide 15a has open cells, does not deteriorate even if it comes into contact with the contents such as liquid cosmetics 11, and loses elasticity even if it is repeatedly compressed. Those without are preferably used. Specifically, dry urethane sponge (polyester type) using polyurethane as the main raw material, wet urethane sponge (polyester type, polyether type) also using polyurethane as the main raw material, acrylonitrile butadiene rubber (NBR) latex, natural rubber (NR). ) Latex, styrene-butadiene rubber (SBR) latex, isoprene rubber (IR) latex, chloroprene rubber (CR) latex and other latex-based latex sponges and the like can be mentioned. In the present invention, a dry urethane sponge is used from the viewpoint of cell size selectability, chemical resistance and the like.

Among the above-mentioned dry urethane sponges, ^{those having the characteristics of an apparent density of 20 to 50 kg / m 3} , an elongation rate of 80% or more, and a number of cells of 10 to 70 cells / 25 mm are particularly liquid makeup. It is used in the present invention because it is excellent in the ability to take in the contents such as the charge 11 and the action of adhering the taken-in contents to the puff or the like at the time of decompression. Incidentally, examples of commercially available dry urethane sponges having such characteristics include malt filter MF-20 (manufactured by Inoac Corporation) and malt filter CFH-30 (manufactured by Inoac Corporation).

The thickness of the disc-shaped elastic body 15b [indicated by T in FIG. 3A] is appropriately set according to the size of the container, the material of the liquid cosmetics 11, and the like, but is generally set to the container body 13. In consideration of the ease of operation of taking out the liquid cosmetic 11 from the recess 12 of the above, it is preferable to set it to about 2 to 20 mm, particularly about 2 to 10 mm. That is, if the thickness of the disc-shaped elastic body 15b is too thin, the elastic deformation of the disc-shaped elastic body 15b may be poor and the usability may be deteriorated. On the contrary, if the thickness is too thick, it is difficult to take out the contents. At the same time, the container becomes too bulky, which is not preferable.

Further, the disc-shaped elastic body 15b does not have to have a disc-shaped shape having a uniform thickness as a whole, and may have a bulging shape, for example, becoming thicker toward the center. Then, the bulging portion may be upward or downward in a state of being combined with the annular guide 15a, but the bulging portion is in a shape of bulging downward from the opening of the annular guide 15a. However, it is preferable in terms of usability.

It is desirable that the outer peripheral shape of the disk-shaped elastic body 15b is set to be one size larger than the outer peripheral shape of the annular guide 15a to which the disc-shaped elastic body 15b is attached, and moreover than the inner peripheral shape of the recess 12 of the container body 13. .. That is, according to this configuration, the peripheral edge portion of the disc-shaped elastic body 15b protruding outward from the annular guide 15a is slightly pressed into the recess 12 of the container body 13, so that the inner lid 15 is fitted in the recess 12. This is because it has the advantage of moving up and down in a stable state along the inner wall surface.

In the above example, the inner lid 15 has a configuration of attaching the disk-shaped elastic member 15b to the upper surface of the annular guide 15a. That is, according to this configuration, the disc-shaped elastic body 15b is supported by the annular guide 15a in a stable state without falling inside the tubular elastic body 14.

Further, the wide-mouthed container of the present invention includes a container body 13 in which a tubular elastic body 14 is fitted in a recess 12, an inner lid 15 in which an annular guide 15a and a disc-shaped elastic body 15b are combined, and a container body 13. Other configurations are not particularly limited as long as they include a lid 16 that covers the upper surface. For example, in the above example, each part such as the container body 13 is an injection molded product, and the container body 13 and the lid 16 are opened and closed by screw engagement, but the container body 13 and the lid are opened and closed. A so-called compact container type in which the body 16 is connected by a hinge may be used. Alternatively, the container body 13 and the lid 16 may slide horizontally with each other so that the upper surface of the container body 13 opens.

The wide-mouthed container of the present invention does not have to be a container having a circular plan view as in the above example, and may be a container having an elliptical or polygonal view in a plan view. In that case, the plan view shape of the tubular elastic body 14 and the inner lid 15 is also set to an appropriate shape according to the plan view shape of the container body 13.

Furthermore, the wide-mouthed container of the present invention can also be applied to a simple sample container for distributing a small amount of cosmetic sample or sending it by direct mail. In that case, each part may be formed into a molded product having a concavo-convex shape by vacuum forming. Further, the content is not limited to the liquid cosmetic 11 and may be a powder cosmetic such as loose powder. Further, it can be applied not only to cosmetics but also to wide-mouthed containers containing various liquid substances and powders.

When the content is powder, the container is turned upside down several times while pressing a puff or the like against the upper surface of the disc-shaped elastic body 15b, and the powder is sprinkled from inside the recess 12 continuously of the disc-shaped elastic body 15b. It can be sprinkled on a puff or the like via air bubbles, and the puff can be used for makeup or the like.

Further, when the content is powder, even if it is difficult to remove the powder from the recess 12 due to agglomeration of the powder, if the disc-shaped elastic body 15b is pushed into the recess 12 using a puff or the like, the circle The plate-shaped elastic body 15b is elastically deformed and comes into contact with the contents, which can be directly scraped off. Then, even if the powder-like contents are scraped off in a lump state, the elastically deformed disc-shaped elastic body 15b has the momentum to return to its original state, and the contents pass through the open bubbles while being loosened, so that the contents go out. When it comes, it has the advantage that the contents are loosened into small pieces and taken out in a uniform state. Therefore, the extracted contents can be used satisfactorily in an even state.

INDUSTRIAL APPLICABILITY The present invention can be widely used as a wide-mouthed container that can contain liquid or powdery contents and take them out little by little for use.
