BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for a liquid container, and more particularly to a lid for a liquid container applicable to cosmetics and household goods containers.

Generally, the contents of cosmetics or daily necessities are divided into powder, solid and liquid products depending on their use, and liquid products are classified into products having high or low viscosity.

In recent years, a cosmetic and household product has a structure (pump) capable of discharging only a certain amount of contents for user's convenience. It is often applied and released.

Such a structure (pump) is designed so that, when the pressure is applied to the button in the vertical direction, the contents accommodated in the form of liquid using the pressure difference can be dispensed only in a predetermined amount from the inside of the container.

Although such a structure (pump) is very convenient in terms of constantly supplying a constant amount, it is composed of a large number of parts, which implies the complexity of its structure and assembly. This inevitably leads to an increase in the unit price, and due to the complicated assembling process and structure, there is a possibility that quality defects such as button restoration failure and ejection failure may occur. Also, due to its special structure, And it is disadvantageous in that it is not free from the aspect of design.

The discharge port may be opened or closed in accordance with a change in pressure inside the liquid container.

The discharge port may be formed of any one of elastomer, NBR, and silicone.

The discharge port may have a shape protruding in a direction toward the opening and closing member.

The discharge port may be deformed and protruded in the direction opposite to the opening / closing member when pressure is generated in the liquid container.

The discharge port may have a cross-shaped hole.

The housing may have a tubular shape whose upper portion is hemispherical and whose lower portion is fixed to the lid body portion.

In the housing, a plurality of holes may be formed on the upper and lower outer peripheries.

The opening and closing member may be positioned to abut the upper or lower inner surface of the housing.

The opening and closing member may have a density lower than that of the liquid.

The opening and closing member 300 is positioned in close contact with the upper portion of the housing 200 in a state where the lid body 100 and the housing 200 are engaged. This is because the opening and closing member 300 is less dense than the liquid inside the liquid container 200.

3 and 4, a description will be given of a process of dispensing a liquid in a liquid container using a lid for a liquid container according to an embodiment of the present invention.

First, when the liquid container lid 10 according to the embodiment of the present invention is coupled with the liquid container 20, the liquid in the liquid container 20 flows through the holes 220 formed in the outer periphery of the lower portion of the housing 200, As shown in FIG. At this time, since the opening and closing member 300 is denser than the liquid, the opening and closing member 300 is positioned closely to the upper portion of the housing 200.

For example, when the user wants to discharge the liquid in the liquid container 20 in a state in which the container lid 10 and the liquid container 20 are engaged, the liquid container 20 is squeezed by the operation of catching the liquid container 20, Thereby generating a pressure inside.

At this time, the liquid inside the housing 200 is discharged to the outside of the liquid container 20 through the discharge port 130 of the lid body portion 100. Here, the discharge port 130 is deformed and opened in a direction opposite to the opening / closing member 300, and the liquid can be discharged to the outside through the discharge port 130 which is opened.

The liquid in the liquid container 20 flows into the housing 200 through the hole 210 in the upper part of the housing 200. At this time, the opening / closing member 300, which blocks the upper part of the housing 200, . The opening and closing member 300 is brought into close contact with the discharge opening 130 of the lid body 100 and the discharge opening 130 in which a predetermined portion of the opening and closing member 300 is opened is closed to prevent the liquid from being discharged to the outside do.

Accordingly, a certain amount of liquid is discharged to the outside of the liquid container 20 until the discharge opening 130 is closed by the opening and closing member 300.

Thereafter, when the pressure in the liquid container 20 is reduced through the user's putting operation, the discharge port 130 is deformed and projected and closed again in the direction of the opening and closing member 300 by the pressure difference between the inside and the outside of the liquid container 20.

The gap member 300 moves toward the upper portion of the housing 200 due to the difference in density between the gap member 300 and the liquid 200. The inside of the housing 200 flows through the hole 220 formed in the outer periphery of the lower portion of the housing 200 It is filled with liquid.

Thereafter, the fixed amount of liquid can be repeatedly discharged through the repetition of the above-described operations.

Therefore, the lid 10 for a liquid container according to the embodiment of the present invention is capable of uniformly discharging the liquid in the liquid container, and unlike the lid provided with the conventional discharge pump, many parts are not complicated, And the manufacturing cost is reduced.

Also, the lid 10 for a liquid container according to the embodiment of the present invention does not protrude to the outside, unlike the lid provided with the conventional discharge pump, and the degree of design freedom increases.
