The present invention relates to a foundation container having a discharge pump having a short stroke distance and a content diffusion member, and more particularly, to a foundation container having a discharge pump having a short stroke distance and a content diffusion member, in which a pump upper body, to which a discharge valve is installed, is vertically reciprocated in a pump main body to change the volume of a content temporary storage space so that the contents are pumped, and a content diffusion member is provided on a top end of the pump upper body such that contents are uniformly diffused in an impregnation member.
A compact container keeps powdered contents therein and the powdered contents are used by using a puff. However, when the powdered contents are used, the contents may be scattered. In addition, when the powdered contents are applied on a face, the adhesion is deteriorated. Thus, there has been developed gel-type foundation in order to overcome such defects. Due to the convenience, the gel-type foundation has been increasingly used.
In general, cosmetics are manufactured by mixing mutually different materials having mutually different specific gravity, and the cosmetic materials may be classified into water-in-oil (W/O) emulsion type cosmetic material and oil-in-water (O/W) emulsion type cosmetic material obtained by mixing water-based material and oil-based material such as an emulsifying agent including a surface active agent.
The water-in-oil emulsion type cosmetic material has a larger quantity of oil than that of water and is oily so that the absorption of skin is slow. Although the touch feeling of the water-in-oil emulsion type cosmetic material is heavy, the persistence is longer than that of the oil-in-water emulsion type cosmetic material. The oil-in-water emulsion type cosmetic material has a larger quantity of water than that of oil and is little oily so that the absorption of skin is fast. Although the touch feeling of the water-in-oil emulsion type cosmetic material is flash and light, the persistence is low. Therefore, the cosmetics requiring persistence are manufactured by using the W/O emulsion type cosmetic material to increase water resistance against sweat and water.
Although the touch feeling of the W/O emulsion type cosmetic material is heavy and sticky, the defects may be compensated by reducing the viscosity of content. However, when the water-in-oil product having low viscosity remains for a long time in circulation, the aqueous material of internal phase and the oil materials of external phase may be separated from each other. In this case, a user shakes a container to mix the separated aqueous and oil materials with each other for use, but it is inconvenient to shake the container for use.
To solve the problems, as shown in
As shown in
However, since the volume of the impregnation member 2000 is great, it is difficult for the push plate 3000 to fully lift up the impregnation member 2000 only by the pumping operation of the airless pump 4000. Therefore, it is difficult to fully use the gel-type foundation impregnated into the impregnation member 2000, so that the contents are wasted.
Thus, as shown in
Although the compact container having an airless pump prevents contents from being residual in a container main body 1000 by using the airless pump 4000, since the airless pump of the compact container according to the related art must use an operating piston 4200 and a sealing piston 4300 due to its structure, the stroke distance is long and, when the airless pump is installed in a flat container such as a compact, the airless pump must be manufactured to have a short stroke distance, so that the discharge amount at a time is small, so pumping must be performed several times to obtain a desired amount. In addition the structure of the airless pump 4000 is complex so that the manufacturing cost is increased.
For reference, the structure of the airless pump will be described as follows. As shown in
The sealing piston 4300 is additionally installed to the operating piston 4200 and a push button 5000 is installed to an operating tube 47000 coupled to the operating piston 4200 of the cylinder 4600.
According to the content discharge pump of the related art having the above described configuration, when the push button 500 is pushed, after a pore is first created between the sealing piston 4300 and the operating piston 4200, the sealing piston 4300 and the operating piston 4200 move down together to generate pressure in a content storage room 4500, so that the contents are discharged through a content transfer path 4220 of the operating piston 4200 by the pressure.
In this case, an opening/closing part 4120 is tightly closed to a content introduction hole 4100 by a compressed elastic member 4400 to shut off the content introduction hole 4100.
After the push button 5000 is pushed to discharge the contents as described above, when the pressure on the push button 5000 is removed, as shown in
At the initial raising stage of the operating piston 4200 and the sealing piston 4300 described above, while the sealing piston 4300 is stopped due to the friction of the sealing piston 4300 and the inside of the cylinder 4600, the operating piston 4200 first moves up, so that the pore created between the operating piston 4200 and the sealing piston 4300 is closed, so that the content transfer path 4220 is shut off and the elastic force accumulated in the elastic member 4400 is weakened.
As described above, in the state that the content transfer path 4220 is shut off, as the operating piston 4200 and the sealing piston 4300 continuously move up by the elastic member 4400, vacuum pressure is generated in the content storage room 4500 and the opening/closing part 4120 is spaced apart from the content introduction hole 4100 by the vacuum pressure generated in the content storage room 4500, so that the contents in the container are introduced into the content storage room 4500.
The content discharge pump according to the related art repeats the above-described operation so that the contents are discharged.
However, the structure of the content discharge pump according to the related art is very complex so that the productivity is deteriorated and the product price is increased. In addition, since the stroke distance of the discharge pump is long due to its structure, when the discharge pump is applied to a product such as a compact, the height of which is less than the width thereof, the space in which the discharge pump is installed is small, so that it is difficult to install the discharge pump. When the discharge pump is manufactured in a small size to solve the problem, the discharge amount of contents is too small so that the pumping must be performed several times to obtain a desired amount of contents.
In addition, although the foundation container having an airless pump according to the related art prevents gel-type foundation from being residual therein, the foundation container does not have any foundations of suitably mixing the separated aqueous and oil materials of the gel-type foundation with each other. Thus, it is inconvenient in use because a consumer must shake the foundation container to mix the aqueous and oil materials with each other.
The present invention has been suggested to solve the problems described above, and an object of the present invention is to provide a foundation container easily operated in a short stroke distance pump, which includes a discharge pump having a short stroke distance such that a pump upper body, to which a discharge valve is installed, is vertically reciprocated in a pump main body to change the volume of a content temporary storage space to pump the contents.
In addition, another object of the present invention is to provide a foundation container which includes an impregnation member provided on an upper end of a discharge pump such that the separated aqueous and oil materials are uniformly mixed with each other.
In addition, still another object of the present invention is to provide a foundation container which is capable of uniformly mixing gel-type contents when the gel-type contents are discharged by an impregnation member, so that the foundation container is not required to be shaken for use.
In addition, still another object of the present invention is to provide a foundation container which includes a content diffusion member provided on an upper end of the discharge pump upper body to uniformly diffuse the contents on an impregnation member so that the contents having a uniform concentration may be used.
In addition, still another object of the present invention is to provide a foundation container which is capable of discharging gel-type contents by using a discharge pump so that the contents are prevented from being residual therein and which is capable of fully using the gel-type contents so that the contents are prevented from being wasted.
In addition, still another object of the present invention is to provide a foundation container which includes a discharge pump having a simple structure to be easily manufactured, so that the productivity is improved and the product price is reduced.
The present invention provides a foundation container which includes a discharge pump having short stroke distance, a content diffusion member, an outer container main body (100), and an outer container lid (150) hinge-coupled to the outer container main body (100) to be opened or closed, which the foundation container includes:
an inner container main body formed in the outer container main body (100);
a supplementary container (370) formed in the inner container main body (300) to contain contents;
an inner container lid (400) for covering an upper part of the inner container main body (300);
an inner container blocking plate (350) coupled to an upper inside of the inner container main body (300);
the discharge pump (600) coupled to a center of the inner container blocking plate (350);
a content diffusion member (700) coupled to the discharge pump (600); and
an impregnation member (800) coupled to an upper part of the content diffusion member (700),
wherein the discharge pump (600) includes a pump main body (10), a pump upper body (20), a pump lower body (30), an absorption valve plate (40), a discharge valve (50) and an elastic member (60).
When a top surface of the pump upper body (20) or the discharge valve (50) of the discharge pump (600) is pressed to move down the pump upper body (20), a volume of a temporary storage space (TR) is reduced to generate pressure in the temporary storage space (TR) so that the absorption valve plate closes a content absorption hole (32). A valve protrusion wheel (52) tightly closed to a content outlet (22) of an extension protrusion wheel (26) is opened by the pressure so that the contents in the temporary storage space (TR) pass through a gap formed between the content outlet (22) of the extension protrusion wheel (26) and the valve protrusion wheel (52). After the contents pass through a flowing path (24) which is a gap between the pump upper body (20) and the discharge valve (50), a discharge pressure is applied to an upper periphery part of the discharge valve (50) so that a gap is formed between an upper surface of the pump upper body (20) and the upper periphery part of the discharge valve (50) and the contents are discharged through the gap.
When a pressure applied onto the top surface of the pump upper body (20) or the discharge pump (50) is removed, the pump upper body (20) moves up due to restoring force of the elastic member (60) and the temporary storage space (TR) in the pump main body (10) is enlarged so that vacuum pressure is generated to close a gap between the valve protrusion wheel of the discharge valve (50) and the content outlet (22) of the extension protrusion wheel (26). A boundary line of an opening/closing line (41) cracks while a central part of the absorption valve plate (40) is lifted up due to the vacuum pressure so that the contents in the supplementary container (370) are delivered into the temporary storage space (TR) while passing through a gap between the absorption valve plate (40) and the content absorption hole (32). The contents passing through the content absorption hole (32) are delivered into the temporary storage space (TR) through a gap of the opening/closing line (41) of the absorption valve plate (40). When the vacuum pressure in the temporary storage space (TR) is removed due to the moving of the contents, the cracked opening/closing line (41) is restored to an original state thereof and closed due to elastic force of the absorption valve plate (40) so that the absorption valve plate (40) closes the content absorption hole (32).
In addition, the inner container main body (300) may be integrated with the outer container main body (100).
In addition, a sealing ring (360) may be further coupled to an outer peripheral surface of the inner container blocking plate (350) to enhance sealing strength.
In addition, preferably, a fixing member (330) is coupled to an upper side of the inner container main body (300) to prevent the inner container blocking plate (350), the content diffusion member (700) and an impregnation member from being separated from each other.
In addition, the inner container lid (400) may be provided at an upper part thereof with a puff keeping space (410) on which a puff lid (420) is formed.
In addition, preferably, a puff (900) is kept in the puff keeping space (410) of the inner container lid (400).
According to the foundation container provided with a discharge pump having a short stroke distance and a content diffusion member of the present invention, the pump upper body, to which the discharge valve is installed, is vertically reciprocated in the pump main body to change the volume of the content temporary storage space so that the contents are pumped.
In addition, according to the foundation container of the present invention, the impregnation member is provided on an upper end of a discharge pump such that the separated aqueous and oil materials are uniformly mixed with each other.
In addition, according to the foundation container of the present invention, the gel-type contents may be uniformly mixed with each other when the gel-type contents are discharged by an impregnated member, so that the foundation container may be conveniently used because the foundation container is not required to be shaken for use.
In addition, according to the foundation container of the present invention, the content spreading member is provided on an upper end of the discharge pump to uniformly spread the contents over an impregnated member so that the contents having a uniform concentration may be used.
In addition, according to the foundation container of the present invention, since the discharging gel-type contents is discharged by the discharge pump, the contents may be prevented from being residual therein, so that the gel-type contents may be fully used, thereby preventing the contents from being wasted.
In addition, according to the foundation container of the present invention, since the discharge pump has a simple structure, the discharge pump may be easily manufactured, so that the productivity may be improved and the product price may be reduced.
