Disclosed is a foundation container having a discharge pump therein, in which a contents container of stretchable material for storing cosmetic contents is coupled inside a container main body, and is fixed by a middle cap, and the contents container is provided with a rounded curved portion (42) at a lower edge thereof, an annular bent portion (43) at a lower center portion thereof, and spaced protrusions (44) protruding radially on an upper bottom surface, such that the contents container is evenly pressed from the rounded curved portion during the pumping operation of the pump, and even when the contents container is compressed, the gap is secured to discharge minimal contents, whereby the contents are smoothly discharged, and by the branch structure of the distribution plate and the discharge plate, it is possible to minimize the residual contents and improve use efficiency while discharging the cosmetic contents evenly.

TECHNICAL FIELD

The present invention relates generally to a foundation container having a discharge pump therein, in which a discharge plate above a container main body is pressed to discharge contents in the container main body by a pumping operation of a pump. More particularly, the present invention relates to a foundation container having a discharge pump therein, in which contents are contained in a contents container of stretchable material inside the container main body, and the contents container is gradually compressed from an outer lower side to a center thereof by pumping operation of a pump to evenly distribute and discharge the contents, thereby minimizing the remaining amount of the contents compared to the conventional container.

BACKGROUND ART

In general, foundations are used for a base makeup and are used to make skin colors uniform and to cover defects. Foundations are classified into solid, liquid or gel types.

The solid foundation has a good covering power, but it has a disadvantage that it is cakey during makeup correction. The liquid foundation has a good adhesion, but it has a weak sustainability. Thus, in recent years, there has been an increase in the number of consumers who prefer the gel foundation having a considerable sustainability and good adhesion properties for skin application.

The gel foundation is conventionally contained in a glass container or a tube container, and is taken out to the user's hand or squeezed and applied to the skin with puff or by hand. However, it is disadvantageous in that since the cosmetic is used by taking it out to the hand, a user should wash hands every time it is used.

To solve the above problem, as in Korean Utility Model Registration No. 20-0470757 (Patent Document 1), there has been disclosed a compact container having an airless pump, which is configured such that between an outer container and a lid, a container main body, a pump, a discharge plate are coupled to each other, and the discharge plate is elastically pressed such that cosmetic contents in the container main body are pumped out and discharged to the discharge plate, and are used with a puff or the like, whereby there is no need to take out the contents by hand, and it is possible to easily carry the compact container.

However, the conventional compact container having an airless pump is disadvantageous in that since, in order to effectively discharge the contents inside the container main body during the pumping operation of the pump, the container main body is provided with a piston at the inner bottom thereof, so that the piston is raised while discharging the contents during the pumping operation of the pump, in the case of the above piston type, the airtightness is deteriorated due to the horizontal disparity thereof, and it is difficult to discharge all the final residual contents, which lowers the user satisfaction considerably.

The conventional compact container is further disadvantageous in that since a contents container of rubber material having elasticity is mounted in the container main body, the contents are discharged while the contents container is pressed during the pumping operation of the pump, the contents container has good airtightness but is not pressed evenly by the pumping force of the pump, and in particular, the contents container is pressed firstly around contents discharge holes, which interferes with the discharge of the contents, so that the discharge of the contents is not smooth, and it is difficult to discharge all the final residual contents, which lowers the user satisfaction considerably.

Therefore, the applicant of the present invention has sought to develop an improved product, which facilitates the discharge of contents, whereby a contents container is evenly compressed by the pumping operation of the pump to minimize the final residual contents, while using a contents container of rubber material having elasticity.

MODE FOR INVENTION

Hereinbelow, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A foundation container having a discharge pump therein of the present invention, as shown inFIGS. 1 to 15, includes: an outer container10; a lid20hinged to the outer container10to be opened and closed vertically; a container main body30mounted in the outer container10; a pump50coupled to an upper center portion of the container main body30; and a discharge plate60coupled to an upper portion of the pump50and formed with contents discharge holes63.

In particular, the container main body30is provided with a ventilation hole31formed through a lower portion thereof, a contents container40of stretchable material (for example, rubber materials such as urethane to prevent deterioration of cosmetic contents) having a space portion41for storing contents is inserted in the container main body, and an upper end of the contents container40is seated on an upper portion of the container main body to be fixedly coupled by a middle cap35coupled to the upper portion of the container main body, such that the contents container40is gradually pressed by pumping operation of the pump50by elastic pressing action of the discharge plate60, so as to discharge the contents to the contents discharge holes63of the discharge plate.

Here, the contents container40is configured such that a lower edge thereof is provided with a rounded curved portion42, and a bottom thereof is provided with at least one annular bent portion43formed to be bent upward and downward at a position outside a pump accommodating portion36of a lower center portion of the middle cap35, so as to induce the contents container to be gradually pressed from the rounded curved portion of the contents container.

Further, the contents container40is provided on an upper bottom surface thereof with spaced protrusions44protruding radially to form a gap t for discharging the contents from an outer wall surface of the pump accommodating portion36of the middle cap when the contents container is pressed.

The outer container10is coupled to a coupling ring body15to fix an inserted state of a button12for opening and closing the lid20in an assembly hole11formed at a front of the outer container.

Here, the button12is provided with right and left tension pieces12a, a locking protrusion12bprotruding from an upper portion thereof to perform locking operation by being engaged with a locking groove21of the lid.

Further, the coupling ring body15is integrally provided at a back thereof with a slit16cut in a circumferential direction, and a tension protrusion17protruding from a center of the slit to provide a tension force at an initial stage of opening the lid20, such that, compared to the conventional case where a tension protrusion is separately provided, it simplifies the structure and further improves tension operation by slit16space.

The pump50includes: a check valve51configured to open and close a through-hole36aformed through a bottom of the pump accommodating portion36at the lower center portion of the middle cap; a fixed piston52inside the pump accommodating portion; a piston rod53configured to open and close a discharge path of the cosmetic contents by vertically moving in the fixed piston; and a distribution plate55coupled to an upper portion of the piston rod to distribute the contents pumped out, wherein the distribution plate55is bonded to a coupling groove65formed in the lower portion of the discharge plate by ultrasonic bonding.

Herein, the distribution plate55is provided at an upper portion thereof with branch passages57formed radially at an equal angle interval from a contents supply hole56at a center of the distribution plate to discharge the contents evenly to the discharge plate, each of the branch passages having a first branch passage57afor guiding discharge of the contents, and at least two second branch passages57bconfigured such that the second branch passages are branched in different directions at an end of the first branch passage to guide discharge of the contents and the contents discharge holes63of the discharge plate60are disposed to be aligned with end portions of the second branch passages.

Meanwhile, the container of the present invention is integrally provided with a refill container100coupled with the container main body30, the middle cap35, the contents container40, the pump50, and the discharge plate60, for refill use by being inserted into the outer container10.

Here, the outer container10is formed at a bottom thereof with an annular assembly hole13, and a stop step14having an inclined portion14ainclined from an upper portion to a lower portion thereof at an upper edge of the assembly hole. The container main body30includes: a ring-shaped coupling protrusion32provided on an outer lower side thereof to be inserted into the assembly hole13of the outer container to prevent separation, with a lower edge thereof formed with a rounded portion32a; and a seat protrusion33provided at a position above the coupling protrusion to be seated in an inner bottom of the outer container.

Herein, the outer container10may be further provided with a knurling portion18on a circumferential surface of an upper bottom thereof, and the seat protrusion33of the container main body30may be further provided with a support protrusion34on a lower surface thereof to be engaged with the knurling portion18to prevent rotation.

It is possible to prevent the container main body30from loosening with respect to the outer container10during the unlocking operation of the discharge plate60through the configuration of the knurling portion18and the support protrusion34.

Further, the container of the present invention is configured such that, when initially provided, the pumping operation of the pump50by the discharge plate60is restricted by a locking structure to prevent malfunctions, wherein the locking structure is configured such that the discharge plate60is provided in an outer side thereof radially at an equal angle interval with stop portions61each having a stop protrusion61aat a lower portion of the outer side and a stop groove61bat a position above the stop protrusion, and the middle cap35is provided in an outer side thereof radially at an equal angle interval to correspond to the stop portion61with a support portion37having a lower support protrusion37afor supporting the stop protrusion61aof the discharge plate to restrict rotation toward lower and first sides thereof, an upper support protrusion37bfor supporting an upper portion of the discharge plate, and a side support protrusion37cfor engagement while being tensioned inward and outward by a slit37dformed on a second side thereof, whereby, at initial use, the stop portion61of the discharge plate is forcibly rotated to be separated from the side support protrusion37cof the support portion, such that the discharge plate is released from a locked state to enable the pump to be operated.

Herein, when the discharge plate60is forcibly rotated, the middle cap35, the contents container40, and the container main body30are prevented from being rotated by the knurling portion18of the outer container10and the support protrusion34of the container main body30being engaged with each other.

As the unexplained reference numerals, reference numerals71and72denote an elastic spring, and reference numeral80denotes a puff.

Hereinafter, the operation and effect of the present invention configured as described above will be described.

Firstly, the button12at the front of the outer container10is pressed to unlock the lid20.

The tension protrusion17of the coupling ring body15coupled to the inside of the outer container pushes the unlocked lid20, and a user rotates the partially opened lid20to fully open the lid20.

Here, the tension protrusion17of the coupling ring body15is operated by a simple structure integrally formed with the coupling ring body15instead of a conventional structure in which urethane rubber or the like is fitted separately, wherein the tension protrusion17is integrally protrudingly formed with the center of the slit16cut at the back of the coupling ring body in the circumferential direction to simplify the assembly structure, and also, the tension protrusion17is tensioned by the slit16to open the lid effectively at the initial stage of the opening.

As described above, after the lid20is opened, the discharge plate60is pressed by the puff80to enable the pump50to be operated. At the initial use, the discharge plate60is locked by the locking structure not to actuate pumping operation, whereby the discharge of the contents is prevented before the initial use.

As described above, the locking structure of the discharge plate should be released at the initial use. As shown inFIG. 15, since the stop protrusion61aof the discharge plate60is supported by being inserted into a space among the lower support protrusion37a, the upper support protrusion37b, and the side support protrusion37cof the middle cap35, the discharge plate is in the locked state where the downward movement and rotation of the discharge plate60are restricted, and in this state, the user forcibly rotates the discharge plate60in the direction of the side support protrusion37c.

Here, as the side support protrusion37cis tensioned inward and outward by the slit37d, the stop protrusion61aof the discharge plate is rotated to be separated from the supported state, wherein since the upper support protrusion37binserted in the stop groove61bof the discharge plate is rotated to the position where rotation is restricted, the lower portion of the stop protrusion61aof the discharge plate is completely separated from the lower support protrusion37a, so as to be in the unlocked state where elastic downward movement is possible.

Herein, when the discharge plate60is forcibly rotated, the middle cap35, the contents container40, and the container main body30are prevented from being rotated since the knurling portion18of the outer container and the support protrusion34of the container main body are engaged with each other.

As described above, in the unlocked state, the discharge plate60is elastically pressed along with the puff80to enable the pump50to be operated, and thus, the cosmetic contents contained in the contents container40inside the container main body is discharged to be used.

To be more specific, in the process of the discharge plate60being elastically moved downward and restored upward by the elastic springs71and72, by the pumping operation where the distribution plate55and the piston rod53are moved downward and then elastically moved upward, the check valve51opens the through-hole36aformed through the bottom of the pump accommodating portion36, and the contents container40inside the container main body is pressed to discharge the contents, whereby the contents are discharged to the distribution plate55and the discharge plate60through the through-hole36aand the discharge path of the pump.

Here, the contents container40inside the container main body is made of stretchable material to be compressed by the pumping force of the pump, wherein the bottom of the contents container40is provided with the annular bent portion43formed to be bent upward and downward at a position outside the pump accommodating portion36of the lower center portion of the middle cap35, and the lower edge thereof is provided with the rounded curved portion42, whereby the contents are discharged while gradually inducing to be pressed from the rounded curved portion42of the lower edge rather than the central position where the bent portion of the contents container is formed.

In other words, since the contents container40is gradually pressed from the lower edge and then the bent portion43of the central portion is stretched and pressed gradually, the cosmetic contents of the contents container are induced to be pressed evenly and the discharge is induced.

In particular, since the contents container40is provided on the upper bottom surface thereof with the spaced protrusions44protruding radially, even when the bottom surface is pressed to be brought into close contact with the outer wall surface of the pump accommodating portion36of the middle cap, the gap t is provided between the contents container and the outer wall of the pump accommodating portion by the spaced protrusions, so that the final residual contents are induced to be smoothly discharged.

Further, as described above, the contents discharged by the pumping operation of the pump are discharged to the first branch passage57aof the branch passage formed radially from the contents supply hole, and to the second branch passages57bconfigured such that the second branch passages are branched in different directions at the end of the first branch passage, through the contents supply hole56at the center of the distribution plate55of the pump, and then at the end of the second branch passage, the contents are distributed and discharged to the contents discharge holes63of the discharge plate, whereby the cosmetic contents are evenly distributed and smeared on the entire lower portion of the puff80to be used.

As described above, the cosmetic contents are evenly smeared on the entire lower portion of the puff80, so that the makeup application can be performed more efficiently.

Meanwhile, when all the cosmetic contents is used up through the above use method, instead of repurchase the entire container, the refill container100, to which the container main body30, the middle cap35, the contents container40, pump50, and the discharge plate60are integrally coupled, can be coupled to the inside of the outer container10for refill use.

In other words, in the state where the lid20above the outer container10is opened, the completely used container main body30, middle cap35, contents container40, pump50, and the discharge plate60are pushed to be forcibly separated from the assembly hole13of the bottom of the outer container, and a new refill container100is coupled thereto.

As shown inFIG. 13, the refill container100, to which the container main body30, the middle cap35, the contents container40, pump50, and the discharge plate60are integrally coupled, is inserted from the upper portion of the outer container10to the inside thereof.

Here, by forcibly inserting the ring-shaped coupling protrusion32formed on the outer lower side of the container main body30of the refill container100into the inclined portion14aof the stop step14at the bottom of the outer container10by the rounded portion32aof the lower edge, the seat protrusion33of the container main body is seated in the inner bottom of the outer container10, whereby the coupling protrusion32is inserted into the assembly hole13, and thus, the refill container is assembled to be prevented from separation by the stop step14and is reusable as described above.
