[0001] Cosmetics container equiped airless-pump [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cosmetic container which enables an amount of contents stored in a container to be discharged by using an airless pump, and more particularly to a cosmetic container which is capable of pushing up the contents close to the contents inlet side of an airless pump The present invention relates to an improved invention replacing a content container filled with a glass material so that the piston can be smoothly operated.

In general, an airless pump is used as a means for discharging the contents contained in a container in an appropriate amount.

The airless pump is designed to discharge a small amount of the contents stored in the container, and thus the airless pump is widely applied to containers containing functional cosmetics and the like.

When the above-mentioned airless pump is operated to discharge the contents, the piston mounted inside the container moves upwards so that the water level of the contents contained in the container can be kept close to the contents inlet of the airless pump.

As described above, the piston which pushes up the contents in the container is required to have a smooth inner surface of the container in which the piston is actuated and a uniform inner diameter with respect to the outer diameter of the piston, due to the characteristics of the piston. However, And has limitations in meeting the characteristics.

The reason for this is that the synthetic resin material is used as a raw material for a content container equipped with a piston which allows the content to always come close to the contents inlet of the airless pump. When the synthetic resin material is left at a high room temperature In addition to the difficulty in using cosmetics without alteration due to the chemical reaction, the chemical reaction causes the inner surface of the container to corrode, which may interfere with the smooth movement of the piston to push up the contents, And the malfunction of the piston may result in lower reliability of the whole product.

When the cosmetic container is made of PP (polypropylene), the contents contained in the container are excellent in chemical resistance to the above-mentioned cosmetic container, , It is opaque due to the nature of polypropylene and has the disadvantage that it can not be confirmed through visual observation of the contents contained therein.

Therefore, it is unsuitable as a material for manufacturing cosmetic containers, which can have a delicate but visual effect and design that can change the product value of the product.

There is not yet a synthetic resin material which can solve the disadvantages of the synthetic resin material and the polypropylene which are exemplified in the above, and the material which can be used as an alternative is glass. However, The piston can not be attached to the container of the cylinder.

A cosmetic container which can solve the disadvantages of the above synthetic resin material and a cosmetic container made mainly of a polypropylene as a raw material and which can be used with a piston made of glass as a raw material is disclosed in the Utility Model Registration No. 20-416530 entitled &Quot; cosmetic container "

In the cosmetic container of the above-mentioned line registration design, the glass tube is cut to a length suitable for the production of a cosmetic container, the piston is mounted in the glass tube, the impact is relieved by the rubber packing mounted on the inner bottom surface of the transparent outer container, The contents can be discharged through an airless pump which is filled with the contents in the contents container whose upper end is blocked and shocked by the rubber packing mounted on the opening member and which is mounted as an opening of the opening member, As the charged content is replaced by a glass tube, not only the deterioration of the contents caused by the chemical reaction caused by the cosmetic container made of synthetic resin is solved, but also the inner surface of the glass tube constituting the content container is smooth, In addition to being able to operate the piston Thereby preventing the occurrence of defective products.

The cosmetic container designed to have the above advantages has a disadvantage in that the number of parts constituting the content container is large as well as the cosmetic container is replaced with a content container. It is difficult to improve assembly productivity because it takes a long time and the rubber packing used to maintain airtightness is in contact with the contents so that the cosmetic container is exposed to direct sunlight or used in an area having high temperature such as the Middle East The rubber packing for airtightness is deformed to a high temperature to cause leakage, and the content of the rubber packing is in contact with the rubber packing to cause the deterioration of the contents in the cosmetic container made of synthetic resin as a raw material The product has not been realized.

Conventionally, a cosmetic container having an airless pump has an air inlet hole formed at the bottom of the outer container so that the piston, which is lifted due to the discharge of contents, can be raised smoothly without vacuum pressure. It has a disadvantage that the hole is clogged, and when the air inflow hole is clogged, there is a problem that the piston can not be stably raised due to a rise in the defective portion.

The object of the present invention is to provide a cosmetic container having a conventional airless pump, which is manufactured by using glass as a raw material for filling the contents and filling the contents with a piston And the thread of the opening formed in a narrowed shape from the shoulder formed on the upper portion of the body is screwed into the container-base engaging thread formed on the inner surface of the container assembly cap constituting the outer container, It is possible to use the cosmetics in a high temperature region because the content is made of pure glass and the chemical reaction that can be caused by exposure to high temperature is fundamentally resolved. Even if cosmetics are used at room temperature, The reliability of the product is ensured and the leakage phenomenon caused by structural defects of the conventional content container formed by assembling a plurality of parts in the conventional glass tube with the content container being composed of a single component is fundamentally And to provide a cosmetic container having an airless pump capable of remarkably lowering the production cost as well as improving the productivity due to assembly and production.

In addition, in order to allow the air to be introduced into the outer container so that the upwardly moved piston can be lifted up without vacuum development, the air inlet hole can be operated without clogging so that the air can be introduced into the undercut screw And the air introduced through the air inlet holes is introduced along the air inlet path formed in the container assembly cap so that the inflow of air necessary for the piston upward can be stably performed, And an airless pump which eliminates the defective discharge of contents.

In order to achieve the above object, the cosmetic container with an airless pump according to the present invention is characterized in that an upper portion is opened so as to allow the contents to be seated, and an undercut screw is inserted into the upper fastening portion of the body, And an inner air introducing passage is formed in a fixing frame constituting the inner container assembling cap, and the inner container is compressed by pressing the fixing frame so that the inner container mounting cap An outer container in which an air inlet hole communicating with the air inlet passage is formed in the undercut screw for fixing the outer container to the outer container,

A lower portion is opened so as to be able to mount a piston for pushing up the contents to the upper portion, and a thread to be threadably fastened to the container base engaging thread formed by extending from the upper shoulder, A container made of a glass material having openings formed therein;

And an airless pump in which the cylinder tube is inserted into the opening portion of the inner container and the thread of the support is tightened and assembled to the pump assembly thread formed on the outer peripheral surface of the inner container assembly cap.

 The inner container assembly cap is formed on an upper portion of a pressure-reducing plate for pressing an upper edge of the opening of the container, and is mounted on a lower outer circumferential surface of the outer container on an upper surface of the outer container, Wherein a screw thread is formed on the inner and outer peripheral surfaces of the pressing ring and the fixing frame, and an inner base screw thread is formed on the inner side to compose the inner tube, and on the outer side, And a pump engagement thread is formed in which the threads of the support are assembled.
