Description

[Technical Field]

[Background Art]

Color cosmetics, which are used to beautifully adorn the skin of a user by making the appearance beautiful, are classified into a base makeup used for making a skin color uniform and covering a defect and a point makeup used for partially enhancing a three-dimensional effect of a lip, eyes, or nails. The base makeup includes a makeup base, a foundation and a powder, and the point makeup includes a lipstick, an eye liner, and mascara.
The foundation is classified into solid-type foundation, liquid-type foundation and gel-type foundation according to a type of cosmetic contents. In case of the solid-type foundation, although the solid-type foundation has a good cover effect, the makeup is united when the makeup is refreshed. In case of the liquid-type foundation, although the liquid-type foundation gives a good close contact feel, the persistency is weak. Thus, in recent years, the number of customers favoring the gel-type foundation having a considerable persistency and a good close contact feel has been increased.
Therefore, there is need to develop a container for gel-type foundation. Generally, the gel-type foundation, which is filled into a glass container or a tub-type container, is used in such a manner that a user takes some foundation on his hands for use or squeezes foundation from the container and then, coats the foundation on his skin by using a puff or his hands.
However, according to the related art, since a user gets cosmetics on his hands every time that it is used, it is inconvenient to wash hands every time after use. In addition, as the hands coated with cosmetics are washed, the cosmetics are wasted.
To solve the above problems, as shown in FIG. 1, a compact container having an airless pump is disclosed in Korean Registered Utility Model No. 20-0470757 issued to the applicant of the present application. According to the related art, as a mixing member is pressed, a distribution plate and a pump are pressed, so that the cosmetics filled in a container body are discharged onto the distribution plate. Then, a user uses the cosmetics impregnated to the mixing member by getting a puff the cosmetics for makeup, so that the cosmetic can be used without coating user's hands with the cosmetics.
However, in the pump according to the related art, although an up-down moving member and a bushing are tightly formed to induce the up-down moving member to vertically move only when the central axis of a piston and the central axis of a cylinder are on the same axis, if a user does not exactly push the center of the mixing member when the user operates the pump, as shown in FIG. 2, the up-down moving member is inclined so that the up-down moving member is trapped by the bushing, so the pump is not operated. Thus, when a user uses cosmetics, the user must press the central portion of the mixing member with a puff to pump the cosmetics. Therefore, the pressing position of the mixing member is limited so that the pump is inconvenient for use.
In addition, according to the related art, since the mixing member is exposed, when the cosmetics is used, the cosmetics impregnated to the mixing member is polluted and oil and moisture are evaporated to dry the cosmetics, so that the function of cosmetics is not fully exhibited.

A mounting wheel (422) protrudes from an upper side of the coupling protrusion (421), such that the mounting protrusion (422) is inserted between the second and third mounting protrusions (14) and (15) of the container body (10).
The pump (50) pumps the contents and like a pump according to the related art, includes the cylinder (51); a suction valve plate (52), a piston (54) and a piston ring (55). However, differently from the pump according to the related art, in order to maximize an area of a content receiving space (31) in the inner container (30), the pump (50) is installed to an upper part of the pump support plate (40) and has a piston-stroke distance in the range of 1.5 mm to 2.5 mm. In addition, the ratio between the piston-stroke distance and an inner diameter of the cylinder (51) is in the range of 1:5 to 1: 13, and the pump (50) has a very short piston-stroke distance and the cylinder (51) of a large inner diameter as compared with the pump according to the related art.

The ratio between a piston-stroke distance and an inner diameter of a cylinder of a pump according to the related art are shown in the following Table 1.

[Table 1]

Piston-stroke distance of pump (mm)	Inner diameter of cylinder (mm)	Ratio	Discharge (cc)
6.3	7.2	1:1.143	0.256
5.8	8.4	1:1.448	0.321
5.2	7.6	1:1.462	0.236
4	7.66	1:1.915	0.184
3.0	9.0	1:3	0.191
3.2	9.7	1:3.031	0.236

As denoted in Table 1, the pump according to the related art has a piston-stroke distance in the range of 3.0 mm to 6.3 mm and the ratio between the piston-stroke distance of the pump and the inner diameter of the cylinder is in the range of 1:1 to 1:3. When the pump according to the related art is employed to a compact container having a short longitudinal length and a long transverse length, the pump is accommodated in the content receiving space while occupying too large area in the content receiving space.
According to the compact container having a pump having a short piston-stroke distance proposed to solve the above-described problem according to the present invention, the piston-stroke distance of the pump (50) is reduced to be in the range of 1.5 mm to 2.5 mm, the ratio between the piston-stroke distance and the cylinder (51) is changed to be in the range of 1:5 to 1;13 in order to enlarge the inner diameter of the cylinder (51), and the pump (50) is mounted on an upper part of the pump support plate (40), so that the content receiving space (31) may be utilized at the maximum.
The pump (50) includes a cylinder (51) formed at a central upper side of the pump support plate (40) and having a content suction hole (58) formed on a bottom surface thereof; a suction valve plate (52) mounted on the bottom surface of the cylinder (51) to selectively open or close the content suction hole (58); a bushing (53) coupled to an outside of the cylinder (51) to be placed on a top end of the cylinder (51); a piston (54) formed inside the cylinder (51); a piston ring (55) fitted with the piston (54) to make close contact with an inner side surface of the cylinder (51); an up-down moving member (56) coupled to an inner periphery surface to move up or down; and an elastic member (57) to elastically support the up-down moving member (56).
An inner extension wheel (561) coupled to the piston (54) extends toward a central lower side of the up-down moving member (56), and an outer extension wheel (562), which is spaced part from the piston ring (55) by a predetermined interval and fitted onto the outside of the piston ring (55), extends toward an outside of the inner extension wheel (561).
In addition, an upper extension wheel (563) coupled to the distribution plate (60) extends toward a central upper side of the up-down moving member (56).
A plurality of slits (564), through which the contents pumped pass, are formed along an outer periphery of the inner extension wheel (561) of the up-down moving member (56).
An upper part of the piston ring (55) is opened outwardly and a close contact wheel (551) protrudes from an upper outer periphery of the piston ring (55). In addition, a piston blade (552), which makes close contact with an inner side wall of the cylinder (51), is formed at a low side of the close contact wheel (551).
A through-hole (53), through which the outer extension wheel (562) of the up-down moving member (56) passes, is formed at the center of the bushing (53). An inner horizontal extension piece extends to an inside of the through-hole (531) and a plurality of elastic member receiving parts (533) are formed at an outside of the through-hole (531). An outer horizontal extension piece (534) fitted into the pump support plate (40) is formed at an outside of the elastic member receiving part (533).
Preferably, an inner side end of the inner horizontal extension piece (532) of the bushing (53) is formed in a round shape.
A gap 59 of 0.3 mm to 1.2 mm is formed between the inner side horizontal extension piece (532) of the bushing (53) and the outer extension wheel (562) such that the up-down moving member (56) may move fluidly in the bushing (53).
That is, the upper part of the piston ring (55) is in an outwardly opened state and the close contact wheel (551) is formed, so that the piston ring (55) is inserted closely into the inside of the outer extension wheel (562) of the up-down moving member (56). In addition, the piston blade (552) is formed at a low side of the close contact wheel (551) to make close contact with the inner side wall of the cylinder (51). For this reason, even though the up-down moving member (56) is pressed in a state that the up-down moving member (56) is inclined to one side, since the inner space of the cylinder (51) is sealed by the piston ring (55), the pump (50) is normally operated.
Thus, even when a user presses not the central portion of the discharge plate (80) vertically but an eccentric portion being out of the central portion so that the up-down moving member, the piston (55) is normally operated in the cylinder (51) so that the contents are easily pumped.
A pair of pressing protrusions (61) are formed on an outer edge of the distribution plate (60) and a content discharge path (62), through which contents moves, is formed on an upper surface of the distribution plate (60). In addition, a coupling hole (63), into which the upper extension wheel (563) of the up-down moving member (56) is inserted, is formed at the center of the distribution plate (60).
The pressing protrusions (61) of the distribution plate (60) are formed at places corresponding to the places of the pressing grooves (71) of the ring button member (70), so that the pressing protrusions (61) are inserted into the pressing grooves (71) of the ring button member (70).
The pressing protrusion (61) of the distribution plate (60) has a semicircular or circular shape so that the pressing protrusion (61) may be easily rotated in the pressing groove (71) of the ring button member (70).
The ring button member (70) is formed in a ring shape and a pressing unit (72) protrudes upwardly from one side of the ring button member (70). A hook (73) is formed at an outer side of the ring button member (70) in opposition to the pressing unit (72), so that the hook (73) is inserted into the hook coupling groove (16) of the container body (10). In addition, the pair of pressing grooves (71) are formed at the places perpendicular to the direction of connecting the pressing unit (72) to the hook (73), respectively.
The pressing grooves (71) of the ring button member (70) are formed in a semicircular or circular shape.
A diameter of the pressing protrusion (61) of the distribution plate (60) is less than an inner diameter of the pressing groove (71) of the ring button member (70).
That is, the pressing protrusion (61) of the distribution plate (60) is formed in a semicircular or circular shape, the pressing groove (71) of the ring button member (70) is formed in a semicircular shape, and the diameter of the pressing protrusion (61) is less than the inner diameter of the pressing groove (71), so that the pressing protrusion (61) may be inserted into the pressing groove (71). For this reason, when a user presses the pressing unit (72) of the ring button member (70) or the discharge plate (80) in order to discharge contents, even though the ring button member (70) or the discharge plate (80) is pressed at an inclined state, the pressing groove (71) of the ring button member (70) changes the pressing center thereof while spinning with no traction, so that the distribution plate (60) can vertically presses the up-down moving member (56) of the pump (50).
The discharge plate (80) is formed on the distribution plate (60). The discharge plate (80) is placed on an upper part of the ring button member (70) while adhering to an upper surface of the distribution plate (60), and is formed with a plurality of discharge holes (81).
Discharge wheels (82) safely placed on the content discharge path (62) of the distribution plate (60) are formed below each of the discharge holes (81), and each of the discharge wheels (81) has an outer periphery, one side of which is opened, such that contents may pass therethrough.
Preferably, the discharge plate (80) adheres to the upper surface of the distribution plate (60) with a dual adhering tape.
A scheme of assembling the compact container having a ring button member described above will be described as follows.
In order to assemble the compact container having a ring button member according to the present invention, as shown in FIGS. 4 and 5, the inner container (30) is installed in the container body (10), one side of which is hinge-coupled to the container lid (20).
Then, after the bottom plate (32) is placed in the inner container (30) and contents is input into the inner container (30), the pump support plate (40) is coupled to the upper part of the inner container (30). The mounting wheel (422) of the lower extension wheel (42) is interposed between the second and third mounting steps (14) and (15) of the container body (10) while the lower extension wheel (42) of the pump support plate (40) is interposed between the inner and outer walls (35) and (36) of the inner container (30).
Next, the pump (50) is mounted on the pump support plate (40) and the distribution plate (60) is coupled to the upper part of the up-down moving member (56) of the pump (50). The ring button member (70) is mounted on the distribution plate (60) while the pressing protrusion (61) of the distribution plate (60) is aligned with the pressing groove (71) of the ring button member (70), and the hook (73) of the ring button member (70) is inserted into the hook coupling groove (16) of the container body (10).
Last, the discharge plate (80) is attached onto the upper surface of the distribution plate (60) while the discharge plate (80) is safely placed at the upper side of the ring button member (70), so that the assembly of the compact container having a ring button member according to the present invention is completed.
The usage of the compact container having a ring button member according to the present invention assembled in such a scheme as described above is as follows.
In order to use the compact container having a ring button member according to the present invention, as shown in FIGS. 7 and 8, a top surface of the pressing unit (72) of the ring button member (70) or the discharge plate (80) is pressed.
When he pressing unit (72) is pressed, the ring button member (70) moves downwardly while being inclined together with the distribution plate (60) installed below the ring button member (70).
In this case, the pressing protrusion (61) of the distribution plate (60) is formed in a semicircular or circular shape, the pressing groove (71) of the ring button member (70) is formed in a semicircular shape, and the diameter of the pressing protrusion (61) is less than the inner diameter of the pressing groove (71), so that the pressing protrusion (61) may be inserted into the pressing groove (71). For this reason, even though the ring button member (70) is pressed at an inclined state, the pressing groove (71) of the ring button member (70) vertically presses the pressing protrusion (61) of the distribution plate (60), so that the distribution plate (60) can vertically presses the up-down moving member (56) of the pump (50).
In addition, when the discharge plate (80) is directly pressed, the distribution plate (60) coupled to the discharge plate (80) is pressed, so that they move downwardly together and the up-down moving member (56) of the pump (50) coupled to the distribution plate (60) moves downwardly.
As the up-down moving member (56) moves downwardly, the piston (54) coupled to the lower part of the up-down moving member (56) moves downwardly together. At this time, since the piston ring (55) is in close contact with the inner side surface of the cylinder (51), a gap is generated between the piston (54) and the piston ring (55) as the piston moves downwardly, so that the content discharge path is formed.
Thereafter, if the up-down moving member (56) is continuously pushed, the piston ring (55) reaches the up-down moving member (56), so that the piston ring (55) moves downwardly together with the piston (54), thereby reducing a volume of the inner space of the cylinder (51). Thus, the contents contained in the cylinder (51) are discharged from the space between the piston (54) and the piston ring (55) to an outside through the discharge hole (81) of the discharge plate 80 after sequentially passing through the slits (564) of the up-down moving member (56) and the content discharge path (62) of the distribution plate (60).
At the same time, the suction valve plate (52) shuts the content suction hole (58) formed on the bottom surface of the cylinder by the discharging pressure in the cylinder (51).
Thereafter, when the pressing on the pressing unit (72) of the ring button member (70) or the discharge plate (80) is released, as shown in FIG. 9, the up-down moving member (56) moves up by the elasticity of the elastic member (57) elastically supporting the up-down moving member (56) and the piston (54) coupled to the lower part of the up-down moving member (56) moves up. In this case, as the extension wheel (541) formed at an outside of the lower end of the piston (54) pulls up the piston ring (55), the piston (54) and the piston ring (55) move up together while the gap between the piston (54) and the piston ring (55) is closed, so that the volume of the inner space of the cylinder is increased, thereby generating a vacuum pressure.
While the suction valve blade (521) of the suction valve plate (52) is lifted up by the vacuum pressure generated from the inside of the cylinder (51), the content suction hole (58) formed on the bottom surface of the cylinder (51) is opened. For this reason, while the contents contained in the inner container (30) are introduced into the inside of the cylinder (51) through the content suction hole (58), the push plate (32) installed in the inner container (30) moves up.
The compact container having a ring button member described in this disclosure is an illustrative purpose only, and 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.
