<First embodiment>

2 and 3 , the cosmetic container assembly according to the first embodiment of the present invention includes a container unit 10 in which a discharge liquid (liquid content) is stored, and a discharge liquid (content liquid) to be discharged. It includes a member 30 , a cap connecting part 20 for connecting the discharging member 30 to the container unit 10 , and a cap 40 accommodating the discharging member 30 for storage.

Referring to FIG. 4 , the container part 10 has a relatively narrow inner diameter, and has a container inlet 11 having a thread formed on the outer circumferential surface. Here, the container unit 10 may be manufactured by injection molding with synthetic resin, glass material, or metal material.

The cap connection part 20 is provided with a screw thread 25 (refer to FIG. 7) on the inner circumferential surface and is coupled to the container inlet 11 of the container part 10 through screw fastening. Also, as shown in FIG. 6 , a plurality of anti-slip ribs 26 are formed on the outer peripheral surface of the body 20a of the cap connection part 20 to prevent slipping during fastening.

In addition, on the upper surface of the cap connection part 20, the inner circumferential upright wall 22 and the outer circumferential upright wall 21 are arranged at regular intervals on a concentric circle. Here, the cap connection part 20 is made of a single recyclable synthetic material and may be manufactured through injection molding. For example, a general-purpose resin such as polyethylene (PE) resin, low density polyethylene (LDPE) resin, high density polyethylene (HDPE) resin, polypropylene (PP) resin, or polystyrene (PS) may be applied.

The discharge member 30 is made of a soft material such as silicone and is installed in a state of being inserted into the inner circumferential surface of the cap connection part 20 . In addition, the discharge member 30 has a discharge hole (H ₁ ) is formed at its tip as shown in FIG. 6 (b). The discharge liquid stored in the container unit 10 may be discharged to the skin through the discharge hole (H ₁ ). Also, a nipple-shaped gripping area 31a is formed on the discharge member 30 . Here, the gripping area 31a may be formed to have a concave shape in the middle so as to precisely control the discharge amount.

In addition, the upper support end 31 and the lower support end 32 are formed to protrude from the outer peripheral surface of the lower portion of the gripping area 31a at regular intervals (see FIG. 6(b)).

Referring to FIG. 5 , the upper support end 31 of the discharge member 30 is fixed in close contact with the upper end of the inner wall 22 of the cap connection part 20 , and the lower support end 32 is the cap connection part (20) is fixed in a state in close contact with the upper end of the inside. In this state, the container inlet 11 of the container part 10 screwed to the cap connection part 20 is fixed to the lower surface of the lower support end 32 in a close contact state. That is, the lower support end 32 of the discharge member 30 has a longer protruding shape toward the outer diameter than the upper support end 31 . Accordingly, since the lower support end 32 is in close contact with the inner circumferential surface of the cap connection part 20 , it is possible to prevent easily leakage to the coupling surface of the discharge member 30 by the pressure gas generated inside the container. Here, the pressure gas is usually easily generated during storage or movement in a state in which liquid contents such as vitamin C solution are accommodated in a cosmetic container.

That is, the lower support end 32 is formed to have an area that is sufficiently in close contact with the inner circumferential surface of the cap connection part 20, so that when the internal pressure gas is generated inside the container part 10 as shown in FIG. Sufficient confidentiality can be ensured.

Referring to FIGS. 4 and 5 , a cap part 40 mounted in a state in which the discharge member 30 is accommodated is installed on the upper part of the cap connection part 20 . Specifically, the cap part 40 has an outer peripheral wall 44 (FIG. 7) into which the outer peripheral wall 21 of the cap connection part 20 is inserted and an inner peripheral wall 43 inserted into the inner peripheral wall 22 of the cap connection part 20. is formed That is, the cap part 40 can secure the airtightness of the discharge member 30 through the double walls 43 and 44 .

In addition, on the lower surface of the upper end side of the cap part 40, the upper end support end 41 and the oil leakage preventing protrusion 42 protruding downward by a predetermined length are formed. Here, the leakage preventing protrusion 42 forms a state inserted into the discharge hole (H ₁ ) of the discharge member 30 .

Referring to Figure 7, the upper support end 41 is formed to match the curvature around the discharge hole (H ₁ ) of the discharge member 30, the leakage preventing protrusion 42 is inserted into the discharge hole (H ₁ ) It can prevent the pressure gas generated inside the container from being easily released to the outside.

That is, cosmetic containers, especially cosmetic liquids such as vitamin C, generate high-pressure gas during movement or storage, which leaks through the sealing surface and may cause minute oil leakage. In addition, there is a risk that external air may be introduced into the container during the pressure gas leaking process, thereby oxidizing or altering the contents of the liquid phase.

Therefore, in order to solve this problem, the present invention provides a structure for improving separation and recyclability by simply separating the discharge member after use while providing an airtight reinforcement structure in the container.

<Second embodiment>

The cosmetic container assembly according to the second embodiment of the present invention provides a structure in which the user can more easily separate the discharging member 30 when discharging separately.

Meanwhile, an inclined end 22a is formed on the inner circumferential surface of the inner peripheral wall 22 of the cap connection part 20 to correspond to the departure guide end 35 of the discharge member 30 .

According to this configuration, the cosmetic container assembly of the present invention can ensure airtightness against pressure gas by forming the lower support end 32 and the inner peripheral surface of the cap connection part 20 and the contact surface C ₁ during use.

In addition, after use, the cap part 40 is separated and the discharge member 30 is easily separated below the cap connection part 20 (in the direction of the arrow in FIG. 8 ), so that the cap connection part 20 made of synthetic resin material and the silicone material are discharged. It is possible to separate and discharge the member 30 and to recycle the cap connection part 20 .

That is, the user (consumer) can easily separate the heterogeneous members through the configuration in which the upper support end 31 of the discharge member 30 is easily separated downward (the inclined end of the cap connection part and the separation guide plate of the discharge member). In addition, it is possible to secure the airtightness to the pressure gas through the close contact surface (C ₁ ) of the lower support end 32 forming structure.
