Generally, cream type cosmetics, such as moisturized cream, massage cream, eye cream, foundation, has a lot of oil, and it is a common knowledge that it can easily be spoiled, compared to low viscosity cosmetics such as skin lotion and lotion. Since these cream-type cosmetics are stored in a container with a wide mouth so as to be taken out a little by a little by hand, it is likely to be oxidized by air contact, and also easily contaminated by foreign substances or moisture on the hand.
To make up for these drawbacks, vacuumed cosmetic containers are widely used to make a certain amount of contents discharged under airtight state. In particular, without being discharged by hand, instead with a plate-shaped button provided are useful, contents can be used after a certain amount of contents is filled.
A traditional vacuum container of these kinds with a plate-shaped button is shown in FIG. 1. Referring FIG. 1, a traditional vacuum container with a plate-shaped button comprises a container body (11) containing contents like cosmetics, a dispenser (12) pumping and discharging a certain amount of contents onto a top portion of the container body, and a button (13) having a plate-shape on an upper portion of the dispenser.
In this configuration, the dispenser (12) comprises a cylinder (14) combined to a top portion of the container body (11) and a piston (17) installed at an inner wall of a suction hole (15) formed on the cylinder (14) so as for the button to repeatedly pump by a spring (16). Furthermore, a check valve (18) is installed at a lower end of the suction hole (15), a piston rod (19) is communicated with the suction hole (15) at the piston (17) and forms an outflow tract for contents to flow out, and a penetrating hole (20) is installed on the button (13), wherein the piston rod (19) is inserted in the middle. In addition, an assisting cap (21), made of soft synthetic resin, is installed on the penetrating hole (20) so as to be elastically deformed by outer pressure and to form a gap.
A vacuum container for cosmetics with a plate-shaped button composed of as the above has a configuration wherein an upper end of a button (13) has a plate-shape which goes deeper as nearer to the center of a top portion, and is formed to use contents by absorbing the contents discharged into a top portion of the button (13) by hand or by an applying tool. By a pumping operation according to pressurization of the button (13), a certain amount of contents is discharged onto a top portion of the button (13); however, since every user needs a different amount of contents, amount of contents by a pumping operation may happen to be more than needed. At this time, the contents which are discharged more than needed may be discarded without being used or unintentionally applied on a skin, thereby leading to unnecessarily consumption of contents and users' excessive cost burdens.
