Description

TECHNICAL FIELD The present invention relates to a wide-mouth container capable of containing a liquid or powdery content and taking out the content little by little for use.

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

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

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

For example, as shown in FIG. 4( a ), the cosmetic container of Patent Document 2 includes a container body 1 for containing the gel cosmetic 10, and an elastic member 2 provided along the inner wall of the container body 1. A mesh frame 4 having a mesh 3 mounted thereon is mounted on the elastic member 2. 5 is an inner lid that covers the opening of the container body 1, and 6 is 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. In order to elastically support the mesh frame 4, as shown in FIG. 4(c), if the puff 7 is pressed downward from above the mesh 3, the mesh 3 is not overloaded and the container body 1 The gel cosmetic 10 inside can be impregnated into the puff 7 side.

Japanese Utility Model Publication No. 62-14973 JP, 2005-188573, A Japanese Patent No. 5188801

As described above, although the cylindrical elastic member 2 reduces the load on the mesh 3, it has an advantage that the mesh 3 is less likely to be damaged. On the other hand, depending on the pushing operation of the puff 7, the mesh 3 is elastic. The gel cosmetic 10 may be deeply soaked together with the member 2, the gel cosmetic may overflow on the eyes of the mesh 3, and the puff 7 pushed in may stick more gel cosmetic than necessary. In this case, the puff 7 must be applied to the opening edge of the container body 1 to drain the liquid, which is inconvenient. In addition, the opening edge of the container body 1 and its periphery are easily soiled with gel 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 powdery 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-mouth container that allows the contents to be taken out little by little and is easy to use.

In order to achieve the above object, the present invention is a container main body having a recess for accommodating contents, and a cylindrical shape having an outer peripheral surface that is fitted into the recess of the container main body and extends along the inner wall surface of the recess. A wide-mouth container having a porous elastic body, an inner lid placed on the upper surface of the cylindrical porous elastic body, and a lid body for covering the upper surface of the container body, wherein the inner lid is An annular guide having rigidity and a substantially plate-shaped open-cell porous elastic body integrally attached to one surface of the annular guide, and the outer peripheral shape of the substantially plate-shaped continuous-cell porous elastic body is A wide-mouthed container which is set to be larger than the inner peripheral shape of the concave portion of the container body and whose contents can be taken out from the concave portion via the continuous cells of the substantially plate-shaped open-cell porous elastic body. This is the first summary.

The present invention, among them, in particular, the upper Symbol cylindrical porous elastic body, a wide mouth container which is closed cell porous elastic body and the second aspect.

Further, the present invention has a wide mouth container, in which the substantially plate-shaped open-cell porous elastic body is any one of a dry urethane sponge, a wet urethane sponge, and a latex sponge, among them, as a third gist, Among them, in particular, the substantially plate-shaped open-cell porous elastic body is a dry urethane sponge, which has an apparent density of 20 to 50 kg/m ³ , an elongation of 80% or more, and a cell number of 10 to 70 cells/ The fourth gist is a wide-mouth container having a size of 25 mm.

In the present invention, the term “substantially plate-shaped” means that the plate is substantially a plate-shaped one, a plate-shaped member having a partially different thickness, or a curved member having the same thickness. It is meant to include things.

That is, the wide-mouthed container of the present invention, in the concave portion of the container body, the cylindrical porous elastic body along the inner wall surface of the concave portion is fitted, the inner lid arranged in the opening of the concave portion, It has a feature that it is composed of an annular guide having rigidity and a substantially plate-shaped open-cell porous elastic body integrally attached to one surface of the annular guide. Then, the content is taken out from the inside of the concave portion via the open cells of the substantially plate-like open cell porous elastic body.

According to this configuration, the substantially plate-shaped open-cell porous elastic body is an elastic body having a shape-retaining property itself, and a large number of open cells distributed therein are a liquid or powder having fluidity. Since it serves as a passageway for the contents of (1), it is convenient to take out the contents little by little through the continuous bubbles.

Moreover, since the substantially plate-shaped continuous cell porous elastic body is integrally attached to one surface of the annular guide having rigidity, even if the continuous cell porous elastic body is pushed deeply, the annular guide is circumferentially moved. Evenly, the position of the cylindrical porous elastic member is lowered while being pressed. Therefore, the open-cell porous elastic body does not tilt and fall into the concave portion, and it can be repeatedly used favorably. Since the open cells of the open-cell porous elastic body can contain a large amount of content, even if the content is pushed deeply, the contents are not formed on the surface side of the open-cell porous elastic body like a conventional mesh. It does not overflow and accumulate, and the puffs will not be overloaded with the contents.

Further, even when the amount of the content is reduced and the bottom of the recess is only slightly, the open-cell porous elastic body supported by the cylindrical porous elastic body is largely elastically deformed to Since the substance can be taken into the continuous bubbles, the contents can be used up to the end without waste.

Further, even if such elastic deformation is repeated, the open-cell porous elastic body itself does not easily lose its shape and does not break, and the upper surface of the cylindrical porous elastic body having cushioning property. Combined with the fact that it is placed in, it can be used satisfactorily for a long time. Also in terms of cost, it has an advantage that it is more economical than conventional meshes and has high versatility.

Particularly , in the wide-mouthed container of the present invention, 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, and the substantially plate-shaped container the continuous peripheral edge of the bubble porous elastic body, for abutting on the inner wall surface pressed into the shape of a recess of the container body, the posture of the open-cell porous elastic body in the recess, Do and that more stable Ttei It

Further, among the wide-mouthed containers of the present invention, in particular, when the cylindrical porous elastic body is a closed-cell porous elastic body, the contents enter the inside of the cylindrical porous elastic body. Since it is not present, the space between the cylindrical porous elastic body and the inner wall surface of the recess is unlikely to be contaminated with the contents, and the appearance is better.

Further, among the wide-mouthed containers of the present invention, in particular, the open-cell porous elastic body is any one of a dry urethane sponge, a wet urethane sponge, and a latex sponge, and among them, in particular, the open-cell porous body. If the elastic material is a dry urethane sponge, the apparent density of which is 20 to 50 kg/m ³ , the elongation rate is 80% or more, and the number of cells is 10 to 70 cells/25 mm, the content is especially insufficient or insufficient. It can be taken out evenly without any problems, making it easy to use.

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 material 11 (see FIG. 2) such as a liquid foundation, and is a relatively short jar type container. The container body 13 having a recess 12 for accommodating the liquid cosmetic 11 and a cylindrical porous elastic body (hereinafter referred to as “cylindrical elastic body”) 14 fitted in the recess 12 are provided. There is. A substantially disk-shaped inner lid 15 is arranged on the upper surface of the cylindrical elastic body 14 in the opening of the recess 12.

More specifically, the container body 13 is an injection-molded product having a substantially bottomed cylindrical shape, and the inside thereof is a recess 12 that accommodates the liquid cosmetic 11. As shown in FIG. 2, the peripheral wall 18 of the container body 13 is formed at its upper portion with a male screw portion 17 for screw engagement with the lid body 16. In addition, an outer cylinder wall 19 is provided below the male screw portion 17 in order to reinforce the container body 13 and to provide a good appearance, thereby forming a double wall.

The tubular elastic body 14 is fitted along the inner wall surface of the container body 13. The tubular elastic body 14 has a tubular shape with a tubular wall thickness of 5 mm, and is made of polyurethane foam in which closed cells are dispersed. As shown in FIG. 2, the height of the cylindrical elastic body 14 is set to be higher than the liquid surface of the liquid cosmetic material 11 when the liquid cosmetic material 11 is full. Therefore, the liquid cosmetic material 11 accommodated in the recess 12 is substantially accommodated in the hollow portion inside the cylindrical elastic body 14.

The inner lid 15 arranged on the upper surface of the cylindrical 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. , A disc-shaped open-cell porous elastic body (hereinafter referred to as "disc-shaped elastic body") 15b integrally attached to the upper surface thereof.

The annular guide 15a is a punched product of a polypropylene sheet having a thickness of 1 mm, and the lower surface thereof, that is, the surface in contact with the upper surface of the cylindrical elastic body 14, is provided with a very shallow uneven pattern S. This is to prevent the annular guide 15a, that is, the inner lid 15, from moving easily on the upper surface of the tubular elastic body 14.

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

As shown in FIG. 2, a packing body 20 for preventing liquid leakage is attached to the inner ceiling surface of the lid body 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, and when the lid body 16 is screwed into the container body 13 and tightened, the packing 20 comes into close contact with the upper end surface of the container body 13. , Liquid tightness is improved.

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

As described above, according to the wide-mouthed container, the disk-shaped elastic body 15b provided in the inner lid 15 is an elastic body having a shape-retaining property itself, and a large number of continuous bubbles distributed inside the elastic body are formed. Since it serves as a path for the liquid cosmetic 11, the liquid cosmetic 11 can be taken out little by little through the open cells.

Even if the amount of the liquid cosmetic 11 becomes small and the disk-shaped elastic body 15b pushed into the recess 12 does not reach the liquid cosmetic 11 in the recess 12 sufficiently, the pushing operation and the releasing operation can be performed. Due to the elastic deformation of the disk-shaped elastic body 15b that accompanies the liquid cosmetic 11, the liquid cosmetic 11 is sucked into the continuous air bubbles so that the liquid cosmetic 11 can be used up to the end without waste.

Even if such elastic deformation is repeated, the disk-shaped elastic body 15b is guided by the annular guide 15a and is stably placed on the cylindrical elastic body 14 having cushioning properties. It can be used satisfactorily repeatedly without losing its shape or tearing. Also in terms of cost, it has an advantage that it is more economical and versatile than a conventionally used mesh [see FIG. 4(a)].

In the present invention, the cylindrical elastic body 14 fitted in the container body 13 is a closed-cell porous elastic body as long as it has an outer peripheral surface along the inner wall surface of the recess 12 of the container body 13. Alternatively, it may be an open-cell porous elastic body. However, the closed-cell porous elastic body is more convenient because there is no possibility that the liquid cosmetic material 11 leaks around the recess 12 through the cylindrical elastic body 14 in the container body 13.

As a material of such a cylindrical elastic body 14, a material that does not deteriorate even if it comes into contact with contents such as the liquid cosmetic material 11 and does not lose elasticity even when repeatedly compressed is preferably used. Specifically, dry urethane sponge mainly made of polyurethane (polyester type), wet urethane sponge mainly made of polyurethane (polyester type, polyether type), acrylonitrile butadiene rubber (NBR) latex, natural rubber (NR) Examples thereof include latex, styrene-butadiene rubber (SBR) latex, isoprene rubber (IR) latex, and latex sponge containing latex such as chloroprene rubber (CR) latex as a main raw material. Of these, dry urethane sponge is preferable in terms of cell size selection, chemical resistance, and the like.

Among the dry urethane sponges, those having characteristics such as an apparent density of 15 to 90 kg/m ³ , an elongation of 70% or more, and a cell number of 10 to 70 cells/25 mm are particularly excellent cushions. It is suitable and suitable. Incidentally, examples of commercially available products having such characteristics include Color Foam EMM (manufactured by Inoac Corporation) and Moltoprene SF (manufactured by Inoac Corporation).

Further, in the present invention, the annular guide 15a of the inner lid 15 does not need to be a polypropylene punch-molded product 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 material 11 or the like as the content. Further, it is not limited to a resin molded product and is not particularly limited as long as it has a certain rigidity. For example, waterproof cardboard, stainless steel, glass, various ceramic molded products, etc. may be used. Good.

The rigidity of the annular guide 15a is set to an appropriate rigidity depending on the material of the disk-shaped elastic body 15b attached to the annular guide 15a, the material of the cylindrical elastic body 14 on which the inner lid 15 is mounted, and the like. .. That is, when the disk-shaped elastic body 15b is repeatedly pressed downward to expand and contract during use, the annular guide 15a has rigidity such that it does not bend or break, and retains the annular shape. Is desirable.

Further, in the above example, a streak pattern S [see FIG. 3(b)] having a very shallow unevenness is provided on the lower surface of the annular guide 15a, and friction between this surface and the upper surface of the cylindrical elastic body 14 is provided. The coefficient is increased to prevent the inner lid 15 from being displaced from the upper surface of the cylindrical elastic body 14, but for the same reason, a small protrusion may be provided on the lower surface of the annular guide 15a in an appropriate arrangement instead of a streak pattern. Good. However, depending on the material of the annular guide 15a, the material of the tubular elastic body 14, etc., the lower surface of the annular guide 15a does not necessarily need to have such an uneven surface.

On the other hand, the disk-shaped elastic body 15b attached to the annular guide 15a has open cells, does not deteriorate even when it comes into contact with contents such as the liquid cosmetic 11, and loses elasticity even when repeatedly compressed. Those without are preferably used. Specifically, dry urethane sponge mainly made of polyurethane (polyester type), wet urethane sponge mainly made of polyurethane (polyester type, polyether type), acrylonitrile butadiene rubber (NBR) latex, natural rubber (NR) Examples thereof include latex, styrene-butadiene rubber (SBR) latex, isoprene rubber (IR) latex, and latex sponge containing latex such as chloroprene rubber (CR) latex as a main raw material. Of these, dry urethane sponge is preferable in terms of cell size selection, chemical resistance, and the like.

Among the above dry urethane sponges, those having characteristics such as an apparent density of 20 to 50 kg/m ³ , an elongation of 80% or more, and a cell number of 10 to 70 cells/25 mm are especially preferable for liquid makeup. The material 11 and the like are preferable because they are excellent in the force of taking in the content and the action of adhering the taken-in content to the puff or the like at the time of decompression. By the way, 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. 3(a)] is appropriately set according to the size of the container, the material of the liquid cosmetic 11, and the like, but in general, the container body 13 Considering the easiness of the operation of taking out the liquid cosmetic material 11 from the inside of the concave portion 12, it is preferable to set it to 2 to 20 mm, especially 2 to 10 mm. That is, if the thickness of the disk-shaped elastic body 15b is too thin, elastic deformation of the disk-shaped elastic body 15b may be poor and the usability may be deteriorated. On the contrary, if it is too thick, it is difficult to take out the contents. In addition, the container becomes too bulky, which is not preferable.

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

Further, the outer peripheral shape of the disk-shaped elastic body 15b needs to be set to be slightly larger than the outer peripheral shape of the annular guide 15a to which the elastic body 15b is attached and further larger than the inner peripheral shape of the recess 12 of the container body 13. Is . That is, according to this configuration, the peripheral edge of the disk-shaped elastic body 15b protruding outward from the annular guide 15a is fitted into the recess 12 of the container body 13 with a slight pressure, so that the inner lid 15 of the recess 12 does not move. This is because it has the advantage of moving vertically along the inner wall surface in a stable state.

In the above example, the inner lid 15 has a structure in which the disk-shaped elastic body 15b is attached to the lower surface of the annular guide 15a, but conversely, the disk-shaped elastic body 15b is attached to the upper surface of the annular guide 15a. It may be configured. That is, even in this configuration, the disk-shaped elastic body 15b does not fall inside the cylindrical elastic body 14 and is stably supported by the annular guide 15a.

In addition, the wide-mouthed container of the present invention includes a container body 13 in which a cylindrical elastic body 14 is fitted in a recess 12, an inner lid 15 in which an annular guide 15a and a disk-shaped elastic body 15b are combined, and a container body 13 of the container body 13. Other configurations are not particularly limited as long as the lid body 16 for covering the upper surface is provided. 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 body 16 are configured to be opened and closed by screw engagement. It may be a so-called compact container type in which the body 16 is connected by a hinge. Alternatively, the container body 13 and the lid body 16 may be configured such that the container body 13 and the lid body 16 slide in the horizontal direction to open the upper surface of the container body 13.

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

Furthermore, the wide-mouth container of the present invention can 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 a molded product in which an uneven shape is provided 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 for storing various liquid substances and powders.

When the content is powder, the container is reversed and shaken up and down several times while pressing a puff or the like on the upper surface of the disk-shaped elastic body 15b, and the powder is discharged from the inside of the recess 12 to the continuous disk-shaped elastic body 15b. It can be thrown out to a puff or the like via air bubbles and used for makeup or the like using the puff.

Further, when the content is powder, even if the powder is agglomerated to make it difficult to take out from the recess 12, if the disc-shaped elastic body 15b is pushed into the recess 12 with a puff or the like, The plate-like elastic body 15b elastically deforms and comes into contact with the contents, and can be scraped directly. Even if the powdery content is scraped off in a lump state, the elastically deformed disc-shaped elastic body 15b returns to its original force, and the content passes through the open air bubbles while unraveling. When it comes in, it has the advantage that the contents are finely loosened and taken out in a uniform state. Therefore, the taken out contents can be satisfactorily used without unevenness.

INDUSTRIAL APPLICABILITY The present invention can be widely used as a wide-mouthed container that can store liquid or powder-like contents and take out the contents little by little for use.
