The present invention relates to a tube container having a vacuum pump, and more particularly, in the outer container made of a synthetic resin material having excellent outer shape resilience, but having a double inner aluminum tube having excellent airtightness and at the same time an inlet of the tube container. By forming a vacuum pump that prevents the inflow of external air and allows the contents to be discharged smoothly in a quantitative manner, the contents can be safely preserved without being influenced by air or light, and the tube container can be maintained in its original shape. In addition, the present invention relates to a tube container having a vacuum pump that enables to discharge the contents in the tube container more effectively.

In general, the tube container is widely used as a container for effectively sealing and storing various contents formed in a gel state such as cosmetics, medicines, toothpaste, and detergents. It is a structure discharged to the exterior.

The most widely known conventional tube container is a tube container formed of an aluminum material, and a tube container made of a laminated tube container and a synthetic resin material has been proposed.

The container made of aluminum has excellent characteristics of preservation of the contents by the airtightness of the tube itself and the non-permeable safety that blocks light and air, whereas the tube is crushed when the tube is pressed for dispensing the contents. Not only does not have a good appearance because it maintains the problem that the contents of the container is not completely discharged.

In addition, in the case of the laminated tube, a laminate made of a laminate of an external polyethylene resin layer and an internal aluminum layer is manufactured by forming a tube. Also, when the tube container is crimped, the tube is left in a distorted state, which not only has a poor appearance but also has a disadvantage of poor manufacturing.

In addition, since the synthetic tube container is mainly manufactured using polyethylene resin, due to the characteristics of the material, it has an advantage in that the appearance is restored to a circular shape when the tube is crimped, and the touch is also good, but the compressed tube is circular When restoring the air from the outside and at the same time the light is transmitted through the surface of the tube, so that the contents easily damaged, there was a problem of poor storage.

The present invention has been made in consideration of the above-mentioned various problems, and its object is to construct a double-tube tube container combining the advantages of each of the aluminum tube and the synthetic tube, while improving its appearance restoration, airtightness, and preservation. A cosmetic container is formed at the discharge port of the tube container to prevent the inflow of air from the outside by forming a vacuum pump that pumps the contents in a fixed quantity to the outside to improve the preservation of the contents as well as the convenience of use and structure. To provide a tube container having a vacuum pump of.

In order to achieve the above object, the present invention forms an outer container made of a synthetic resin having excellent outer shape and at the same time, an inner tube of aluminum material having excellent airtightness and preservation is formed in a double structure to easily store the contents. And a vacuum pump to prevent the outside air from flowing into the inside while discharging the contents to the outside by the pumping force at the inlet of the tube container safely without the influence of air or light. In addition, the contents can be stored at a constant rate as a pumping method rather than a crimping method, so as to reduce the waste caused by excessive discharge of the contents and to facilitate the use, and the appearance of the tube container is always kept in a circular shape. It is characterized by improving the appearance.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

In Figures 1 to 3 of the accompanying drawings showing the overall appearance of the present invention, the reference numeral 100 in the drawing indicates the cosmetic container body of the present invention.

The main body 100 is composed of a tube container 10 made of a tubular shape, and a vacuum pump 20 to be detachably formed on the outlet of the tube container 10 to discharge the contents to the outside in a fixed quantity.

The tube container 10 is formed in a double structure of the inner container 12 made of aluminum inside the outer container 11 formed of a synthetic resin.

The outer container 11 is formed of a polyethylene resin having excellent circular restoring force, and an upper spout 14 having a screw 13 on the outer surface and a hard shoulder surface 15 are integrally formed on the upper surface and the lower portion is heat-sealed. The seal 16 to be sealed is provided.

Therefore, the outer container 11 is flexible and has a characteristic of excellent circular restoration, and on one side, an air distribution hole 17 through which air can be distributed is perforated.

In addition, the inner container 12 provided in the outer container 11 is formed of an aluminum material through which light does not penetrate, and the lower end of the outer container 11 is adhered to the inner surface of the shoulder surface 15 of the outer container 11. Adhesion is formed by heat fusion together with the seal 16.

At this time, the inner container 12 of the aluminum material is heat-sealed as the inner and outer surfaces are coated with polyethylene resin.

Therefore, as the inner container 12 has a dual structure in which the inner container 12 is formed, a certain space 18 is formed between them due to the diameter difference thereof, so that the contents in the inner container 12 are external. Even if it is discharged to the contraction, the outer container 11 is to maintain the atmospheric pressure state through the air distribution hole 17 is to maintain the original shape as it is.

On the other hand, the tube container 10 as another embodiment of the present invention may be applied to a general multi-layer tube (Multi layer tube).

Multi-layer tube is a container for storing functional cosmetics, such as retinol, that is easy to deteriorate.The structure is almost the same as general laminate tube used as toothpaste tube, but general laminate tube is bonded to the outer side. The tube is bonded to the inner surface has the advantage that the adhesive surface is not exposed in appearance.

Although the structure of such a multi-layer tube is not shown in the drawings, the outer shape is the same as the tube container 10 described above, the present invention can be applied, the cross-section structure from the outside to the inside PE 0.2mm, ADMER 0.03mm, AL 0.03 mm, adhesive 0.045mm, PET 0.02mm, adhesive 0.045mm LLDP 0.08mm are stacked in order to have a total thickness of 0.45mm.

In addition, the vacuum pump 20 screwed to the spout 14 of the tube container 10 is to discharge the contents to the outside by a fixed amount through the nozzle by pressing the operation button, the contents to the outside While discharging, the outside air is prevented from entering the inside.

As such a vacuum pump 20 has been proposed so far, even if a vacuum pump having any structure prevents external air from flowing into the container and easily discharges the contents, the vacuum pump having any structure may be applied. It will be alright.

In the accompanying drawings, the vacuum pump 20 is shown in detail by way of example.

It is equipped with a nozzle cap 21 is screwed to the spout 14 of the tube container 10, the operation button 22 for the user to press the hand by pressing on the top of the nozzle cap 21 is returned While being elastically installed by the spring 23, the cylinder 24 is assembled to the lower portion.

The fluid passage tube 25 is integrally formed at the lower portion of the operation button 22 to guide the discharged contents to the outside through the nozzle 26, and a piston 28 having a valve 27 at a lower end thereof therein. ) Is fastened, and a piston valve 29 is formed between the lower end of the piston 28 and the fluid passage pipe 25.

In addition, the piston valve 29 is moved up and down along the inner diameter of the cylinder 24 to compress the inside, the contents are discharged and guided to the outside through the space between the piston valve 29 and the piston 28 during compression. .

In addition, the center of the piston 28 is inserted into the shaft valve 30 for opening and closing the lower inlet 31 of the cylinder 24, the ball valve 32 is fastened to the inlet 31 The opening and closing operation will be performed in duplicate.

Therefore, the present invention constituted as described above uses the vacuum pump 20 in the tube container 10 having a dual structure, and the tube container 10 is a synthetic resin as proposed in the Utility Model Registration No. 164779, which was previously filed by the applicant. An inner container 12 made of aluminum is formed in the outer container 11 made of material.

That is, the upper end of the inner container 12 is integrally bonded to the upper shoulder surface 15 in the outer container 11, and the lower end is sealed by heat adhesion while having a predetermined space 18 therebetween. Gel content is filled in the inside of (12).

Cosmetic container 100 according to the present invention can not only safely protect the contents from the external air because the external air is not introduced into the container by the vacuum pump 20 as usually shown in the accompanying drawings. In addition, the inner container 12 of the dual structure can be safely protected from light.

That is, as the operation button 22 is raised by the return spring 23 of the vacuum pump 20, the piston 28, the piston valve 29, the axial valve 30, and the like are lifted to their original positions, so that the cylinder 24 is moved into the cylinder 24. The discharge is waiting to discharge the contents in the tube container 10 is filled.

When the contents are to be extracted in such a state, when the operation button 22 of the vacuum pump 20 is pressed without compressing the tube container 10, the operation button 22 is lowered while compressing the return spring 25. By the lowering operation button 22, the fluid passage tube 25 and the piston 28 are first lowered by the interval (L) of the preliminary section as shown in FIG.

Accordingly, the end surface of the fluid passage tube 25 is brought into contact with the upper working groove of the piston valve 29, and at the same time, the lower valve 27 of the piston 28 is spaced apart from the lower surface of the piston valve 29. A fluid passage is formed between the contents.

At this time, as the piston 28 descends, the axial valve 30 coupled to the center of the piston is also lowered by the frictional force, thereby blocking the inlet hole 31 in the cylinder 24, and at the same time, the ball valve 32 is also lowered to block the inlet hole 31 in a double.

Subsequently, the fluid passage pipe 25 continuously lowers the piston valve 29 as shown in FIG. 6 by the continuously descending operation button 22, so that the piston valve 29 compresses the compression chamber in the cylinder 24. .

Accordingly, the contents in the compression chamber are connected between the center hole of the piston valve 29, the inner diameter of the fluid passage tube 25, and the piston 28 through the fluid passage opened between the piston 28 and the piston valve 29. As it rises through it, it is discharged to the outside through the nozzle 26.

On the contrary, when the operation button 22 held down is released, the operation button 22 is moved up to the original position by the elastic force of the return spring 23. At this time, the lowered piston 28 and the fluid passage as shown in FIG. The pipe 25 first blocks the fluid passage in the state of being raised by the interval L.

That is, when the piston 28 and the fluid passage pipe 25 is raised by the distance (L), the piston 28 and the piston valve 29 are coupled to each other to block the fluid passage therebetween.

Subsequently, the piston valve 29 is lifted up by the lifting operation to generate a vacuum pressure in the cylinder 24. As a result, the axial valve 30 and the ball valve 32 are raised to open the inlet hole 31. By doing so, the contents in the tube container 10 are introduced into the cylinder 24 through the inlet hole 31.

Therefore, the above operation is performed by one push operation of the operation button 22 to discharge the contents in the tube container 10 through the nozzle 26 one by one.

When the contents in the tube container 20 are discharged by the operation of the vacuum pump 20 as described above, the inner container 12 of the tube container 20 is reduced in volume by the amount of the contents being discharged due to the characteristics of the aluminum material. While maintaining the compressed state as it is, on the other hand, the outer container 11 maintains the circular shape as it is due to the characteristics of the synthetic resin material.

That is, the inner container 12 of the aluminum material is to maintain the compressed state while the contents are discharged and reduced by volume due to the characteristics of the material itself, and the outer container 11 is air flow hole punched in a predetermined position At 17, external air is circulated and at the same time, it maintains a circular shape due to the characteristics of synthetic resin material.

As described in detail above, the present invention forms the tube container in a double structure having different materials from each other, that is, the inner container is formed of an aluminum material having excellent airtightness and preservation, while the outer container is formed of a synthetic resin material having excellent external shape resilience, In addition, by forming a vacuum pump in the inlet of the tube container has the advantage of effectively preserving the contents from air or light, as well as the appearance of the tube container is always maintained as it is to improve the appearance and productability Will have
