This application claims the benefit of Korean Application No. 20-2013-0010347, filed on Dec. 12, 2013 with the Korean intellectual Property Office, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a foundation container including a discharge pump having a short working stroke, and more particularly, to a foundation container including a discharge pump having a short working stroke, the discharge pump being configured such that a pump upper body, which has a content discharge port formed therein, is fitted into an upper portion of a pump main body, which has a content intake port formed therein, a pump inner body, which has an intake valve plate formed thereon, is fitted into the pump main body and the pump upper body, and a discharge valve wing of a discharge valve is coupled to a sealing protruding ring on the upper portion of the pump upper body, thereby vertically moving the pump upper body with respect to the pump main body, such that the volume of a temporary content storage part of the pump inner body is changed, thereby discharging the contents, the foundation container including a content diffusion plate formed integrally with an upper body upper plate of the pump upper body such that the contents are discharged by a predetermined amount, diffused by the diffusion plate, evenly applied on a puff, and then used.

BACKGROUND ART

Conventionally, powder-phase contents are received in a compact container, and a user the powder-phase contents using a puff. However, when the user uses the powder-phase contents, the contents may be scattered in use. When the user applies the contents to the face, the adhesion of the contents to the face may be degraded. In order to solve the problem, foundation having the gel-phase contents has been developed, and the use frequency of the foundation has been gradually increased due to the convenience of use.

In general, the gel-phase contents are produced by mixing mutually different materials, and include emulsified cosmetic materials of water-in-oil (W/O) and oil-in-water (O/W) emulsion cosmetic materials obtained by mixing water-based material and oil-based material using an emulsifying agent including a surface active agent.

The water-in-oil emulsion 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 cosmetic material is heavy, the persistence is longer than that of the oil-in-water cosmetic material. The oil-in-water emulsion 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 cosmetic material is flash and light, the persistence is low. Therefore, the cosmetics requiring persistence are produced by using the W/O emulsion cosmetic material to increase water resistance against sweat and water.

Although, the touch feeling of the W/O emulsion 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 must shake a container to mix the separated aqueous and oil materials with each other for use, which causes the inconvenience of use.

In order to solve the problem, as shown inFIG. 1, there has been developed and suggested a product including an immersing member immersed with a W/O contents having low viscosity and contained in an airless pump container, which is disclosed in Korean Unexamined Patent No. 10-2013-0001688.

As shown inFIG. 1, an immersing member2000immersed with gel-phase foundation is contained in a container main body1000. In order to use the gel-phase foundation immersed in the immersing member2000, a user presses a pressing button5000so that vacuum pressure is generated in the container main body1000through the pumping operation of an airless pump4000. A pushing plate3000placed at a lower portion of the container main body1000is moved up by the vacuum pressure. Accordingly, the immersing member2000immersed with the gel-phase foundation is squeezed and compressed up by the pushing plate3000, so that the gel-phase foundation is discharged and used.

However, since the immersing member2000has a large volume, the pushing plate3000may not completely push up the immersing member2000only through the pumping operation of the airless pump4000. Accordingly, the gel-phase foundation immersed in the immersing member2000is not used up, so that the contents may be wasted.

Accordingly, in order to prevent the gel-phase foundation from remaining, there has suggested a compact container having an airless pump which is disclosed in Korean Utility Model Registration No. 20-0461424 as shown inFIG. 2.

Since the compact container having the airless pump employs the airless pump4000, the foundation can be prevented from remaining in the container main body1000. However, since the airless pump of the conventional compact container must employ an operating piston4200and an enclosed piston4300due to the structure, a long working stroke is formed. Accordingly, when the airless pump is installed in a flat container such as a compact, the working stroke must be short. In this case, since a small amount of contents are discharged at once, the user must inconveniently pumping the airless pump several times, which complicates the structure of the airless pump4000and increases the production costs.

For reference, the structure of the airless pump will be described below. Regarding the structure of the airless pump, as shown inFIGS. 3 and 4, an open/close member4120to open/close a content introduction hole4100, and the operating piston4200are installed to receive the elasticity of an elastic member4400. A cylinder4600, which is configured to discharge contents from a content storage chamber4500through a pressing button5000when pressure is applied into the content storage chamber4500by the operating piston4200, is installed in a pump main body4800.

The enclosed piston4300is additionally installed in the operating piston4200, and the pressing button5000is installed in an operating tube4700coupled to the operating piston4200of the cylinder4600.

According to the convention content discharge pump having the above configuration, if the pressing button5000is pressed, after the air gap is first formed between the enclosed piston4300and the operating piston4200, the enclosed piston4300and the operating piston4200are moved down together, so that pressure is generated in the content storage chamber4500. The contents of the operating piston4200are discharged through a content transfer path4220by the pressure.

In this case, the open/close member4120makes close contact with the content introduction hole4100due to the compressed elastic member4400to block the content introduction hole4100.

If the pressure applied to the pressing button5000is released after discharging the contents by pressing the pressing button5000as described above, the operating piston4200and the enclosed piston4300are moved up together by rebound elasticity accumulated in an elastic member4400as shown inFIG. 4.

The operating piston4200and the enclosed piston4300moved up as described above are stopped since the enclosed piston4300makes friction with the inside of the cylinder4600in the initial moving-up stage. In this state, the operating piston4200is first moved up to close the air gap formed between the operating piston4200and the enclosed piston4300so that the content transfer path4220is blocked, and the elasticity accumulated in the elastic member4400is weakened.

In the state that the content transfer path4220is blocked as described above, as the operating piston4200and the sealing piston4300are continuously moved up by the elastic member4400, the vacuum pressure is generated in the content storage chamber4500. The open/close member4120is separated from the content Introduction hole4100by the vacuum pressure generated in the content storage chamber4500, so that the contents in the container are introduced into the content storage chamber4500.

The conventional content discharge pump continuously repeats the above operations to discharge the contents.

However, the structure of the conventional content discharge pump is very complicated, so that the productivity may be degraded, and the price of a product may be increased. In addition, since the discharge pump has a long stroke in terms of a structure, when the discharge pump is applied to a product, such as a compact, having a height lower than a width thereof, the mounting space for the discharge pump is narrow, so that the discharge pump may not be mounted. If the size of the conventional discharge pump is reduced in order to overcome the above problem, an amount of discharged contents is excessively reduced, so that the user must pump the discharge pump several times.

Further, according to the conventional foundation container having the airless pump, although the gel-phase foundation can be prevented from remaining, the foundation container has no function of properly mixing the gel-phase foundation divided into W/O and G/W materials. Accordingly, a consumer must inconveniently use the foundation by shaking the foundation container and mixing W/O and O/W materials, which are divided into each other.

Therefore, applicant of the present invention has suggested a foundation container including a discharge pump having a short stroke and a content diffusing member, which is disclosed in Korean Utility Model Application 20-2013-585S as shown inFIG. 5.

In the foundation container, an outer container cap150is hinged with an outer container body100, an inner container body300coupled to an inner container cap400is mounted in the outer container body100, an inner container interruption plate350is coupled to an inner upper portion of the inner container body300, a discharge pump600is coupled to the center of the inner container interruption plate350, a content diffusing member700is coupled to the upper portion of the discharge pump600, and the discharge pump600is coupled to the inner container interruption plate350.

The discharge pump600used in the foundation container includes a valve body610, a valve late640, a pressing button650, a deformation-press member660, and an elastic member670as shown inFIG. 6.

The valve body610includes a valve upper body620and a valve lower body630. The valve upper body620is formed at an upper surface thereof with a mounting step622, at an inner central portion thereof with a valve plate supporting step624, which protrudes, and formed with a valve lower body coupling part626integrally extending downward. The valve lower body630is formed at the center thereof with a content discharge port632. After the valve plate640is placed on the valve lower body630, the valve lower body630is inserted into the valve lower body coupling part626.

The pressing button650is coupled to an outer circumferential portion of the valve upper body620and formed at the center thereof with a discharge port651to discharge contents. A content open/close member653is coupled to an inner portion of the discharge port651by a rib652.

The deformation-press member660is coupled to the inner portion of the pressing button650. The deformation-press member660is formed at an outer circumferential portion thereof with a coupling step664, which protrudes, to be mounted on the mounting step622of the valve upper body620. The deformation-press member660is formed at the center thereof with a valve protruding ring. The deformation-press member660is mounted on the valve upper body620to form the internal space between the deformation-press member660and the valve body610. The internal space serves as a temporary storage part TR where contents stay before being discharged through the discharge port651of the pressing button650after moving through the content discharge port632of the valve lower body630from the container. In addition, the elastic member670is placed on the coupling step664formed at the edge of the deformation-press member660to press the coupling step664of the deformation-press member660with respect to the mounting step of the valve upper body620, so that airtightness is increased and the pressing button650is elastically supported.

However, according to the foundation container of the related art, the content discharge pump mounted in the foundation container has a significantly complex structure, and a large number of components are provided, so that the product price is increased. In addition, the components have small sizes and the assembling of the components is difficult, so that the production cost may be increased and product competitiveness may be degraded.

The discharge-valve coupling member59is formed at a lower portion thereof with first and second coupling protruding rings591and592to form a coupling groove593, which is coupled to the auxiliary coupling protruding ring572of the discharge valve57, between the first and second coupling protruding rings591and592. The coupling protruding ring591is formed in a lateral side thereof with a coupling groove594coupled to a coupling step545of the discharge valve coupling space542of the pump upper body54, and formed at an upper portion thereof with a second content discharge port595to discharge the contents.

Hereinafter, an assembling method of the foundation container including the discharge pump having the short working stroke, which has the above configuration according to the present invention, will be described.

The outer container main body10is hinged with the outer container cap20. In addition, the container main body30, the container cap40, and the puff cap42are hinged with each other.

Further, the container main body30coupled to the container cap40is inserted into the outer container main body10in the state that the container cap40is open, and coupled to the outer container main body10. The subsequent assembling process is performed in the state that the container cap40is open from the container main body30.

After coupling the thin auxiliary container32or the pushing plate3000to the inner portion of the container main body30, the container interruption plate34, the discharge pump50, and the content diffusing plate60are coupled to the upper portion of the container main body30. Hereinafter, the details will be described.

After coupling the thin auxiliary container32or the pushing plate3000to the inner portion of the container body30, the container interruption plate34is coupled to the upper portion of the container main body30.

In addition, the pump inner body56is mounted in the pump main body52formed integrally with the container Interruption plate34. In detail, the lower coupling extension piece568of the pump inner body56is inserted into the inner body coupling groove525, and the lower side surface extension piece567is undercut-coupled to the inner body locking step524, and the intake-port annular protrusion523is inserted into the close contact groove569-1of the intake valve plate563, and coupled to the close contact groove569-1of the intake valve plate563.

Next, after the elastic member58is fitted around the pump inner body56, the lower end of the elastic member58is mounted on the lower side surface extension piece567of the pump inner body56, and the upper end of the elastic member58is located to elastically support the lower portion of the upper side surface extension piece566of the pump inner body56.

In addition, the pump upper body54is coupled to the upper portion of the pump inner body56, and the pump upper body54is formed integrally with the content diffusing plate60.

The upper side surface extension piece566of the pump inner body56is inserted and coupled between the first coupling-extension member546and the second coupling-extension member547of the pump upper body54, and the lower end of the first coupling-extension member546is coupled in contact with the horizontal connection piece564of the pump inner body56. A coupling protrusion61of the content diffusing plate60formed integrally with the pump upper body54is fitted into a coupling groove341of the container interruption plate34.

Thereafter, the discharge valve57is inserted into the discharge valve coupling space542of the pump upper body54so that the discharge valve wing571makes close contact with the outer circumference of the sealing protruding ring544. The discharge valve57is forcibly inserted into or undercut-coupled to the discharge valve coupling space542of the pump upper body54. Alternatively, the discharge valve57may be coupled to the discharge valve coupling space542by further using the discharge-valve coupling member59.

When the discharge-valve coupling member59is used, the discharge-valve coupling member59is coupled to the upper portion of the discharge valve57. In this case, the discharge-valve coupling member59is inserted into the discharge valve coupling space542of the pump upper body54. In addition, the coupling groove594of the discharge-valve coupling member59is coupled to the coupling step545of the pump upper body54.

Next, the fixing member80is fitted between the outer wall35and the inner wall36of the container main body30. In this case, the top surface of the fixing ember80presses an outer upper portion of the container interruption plate34and the outer upper portion of the content diffusing plate60to prevent the deviation of the container interruption plate34and the content diffusing plate60.

If necessary, as shown inFIG. 17, the immersing member70may be securely mounted on the content diffusing plate60for the use thereof.

Hereinafter, the operation of the foundation container including the discharge pump having the short working stroke according to the present invention as described above will be described.

In order to use the contents of the foundation container including a discharge pump having short working-stroke as configured above, the upper portion of the pump upper body54or the immersing member70is pressed by the puff90.

If the pump upper body54is moved down by the pressing, the inner body barrel wall561of the pump inner body56is folded, so that the volume of a temporary content storage part TR is reduced. Accordingly, pressure is applied to the temporary content storage part TR, and contents are intended to be discharged to the outside from the temporary content storage part TR due to the pressure. Accordingly, the intake valve plate563closes the content intake port522due to the discharge pressure. Simultaneously, the contents are pushed out of the temporary content storage part TR through the content discharge port543, so that the discharge valve wing571of the discharge valve57in close contact with the sealing protruding ring544is spread, so that the contents are discharged to the outside.

When the discharge-valve coupling member59is coupled, the contents, which are discharged as the discharge valve wing571of the discharge valve57is open after passing through the content discharge port543, are discharged to the outside through the second content discharge port595of the discharge-valve coupling member59.

Thereafter, as shown inFIG. 12, if force applied to the pump upper body54is released, the pump upper body54is moved up due to the elasticity of the elastic member58while the inner body barrel wall561of the pump inner body56is returned to an original state thereof. Accordingly, the space of the temporary content storage part TR is increased, in the pump inner body56, so that the vacuum pressure is generated.

Accordingly, the discharge valve wing571of the discharge valve57makes close contact with the sealing protruding ring544to close the content discharge port543, and the central portion of the intake valve plate563is lifted up due to the vacuum pressure in the temporary content storage part TR, so that the gap between the intake-valve-plate annular protrusion569and the intake-port annular protrusion523is increased. Accordingly, the contents in the thin auxiliary container32are moved into the temporary content storage part TR.

As the contents in the thin auxiliary container32is moved into the temporary content storage part TR of the discharge pump50, the vacuum pressure is generated in the thin auxiliary container32. Accordingly, the thin auxiliary container32is separated from the container main body30and shrunken as shown inFIG. 12.

In addition, according to another embodiment, when the pushing plate3000is mounted in the container main body30instead of the thin auxiliary container32as shown inFIG. 1, the pushing plate3000pushes the contents toward the content intake port of the discharge pump50by the vacuum pressure generated as the contents are moved into the content temporary place TR of the discharge pump50from the container main body30.

The contents passing through the content intake port522are moved into the temporary content storage part TR of the pump inner body56. If the vacuum pressure of the temporary content storage part TR is disappeared as the contents are moved, the intake valve plate563is returned to the original state due to the elasticity of the elastic piece562, and the intake-valve-plate annular protrusion569makes close contact with the intake-port annular protrusion523to close the content intake port522.

The contents discharged through the pumping operation of the discharge pump50are moved to the content diffusing plate60. In this case, a user can apply the contents to the puff90for the use thereof.

When the immersing member70is mounted on the content diffusing plate60, the contents, which have been moved to the content diffusing plate60, are uniformly immersed into the entire portion of the immersing member70. Accordingly, the user applies the contents to the puff90for the use thereof.

As described above, although the foundation container including the discharge pump having the short working stroke has been described according to one embodiment of the present invention for illustrative purpose, the present invention is not limited thereto. Thus, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art within the spirit and scope of the present invention and they will fall within the scope of the present invention.
