Cosmetics are products used to beautify the human body's appearance, cover defects in appearance, make it look attractive, or maintain health such as skin and hair.

The cosmetics are classified into basic cosmetics, color cosmetics, and functional cosmetics depending on the purpose of use, and are manufactured in liquid or gel form, solid or powder form according to their characteristics, and are stored and used in various types of cosmetic containers.

Accordingly, it has become necessary to develop containers for various types of cosmetics. In general, liquid or gel cosmetics are filled in a tube container for usability and convenience, and when used, the user can put it on the hand or use a cosmetic tool. It was used in a way of applying to.

In general, a tube container is composed of a tube body made of a soft material, which contains a gel-like material with high viscosity inside, and a shoulder that is coupled to the upper portion of the tube body and has a discharge port, and a tube lid that opens and closes the discharge port. When the soft tube body is pressed, the contents are discharged to the outside through the discharge port of the shoulder.

The tube container as described above is a tube container made of aluminum, a laminated tube container, and a tube container made of synthetic resin, and the aluminum container is airtight and impermeable to block light and air. The safety of the contents is proven, and the contents are excellent in preservation.However, when the user presses the tube to extract the contents, the tube remains crushed, so the appearance is not good, and the contents in the container are not completely discharged. There is a problem with poor mass productivity.

Thus, in recent years, a tube container made of synthetic resin is mainly used, and the tube-type cosmetic container used to hold cosmetics is mainly made of high-density polyethylene (HDPE, High-Density Polyethylene) as a main material to separately mold the tube head and the tube body. One end of the body is thermally pressurized to seal it, and the tube head having a discharge port at the other end is bonded to each other through a method such as bonding or thermal pressurization to form a tube container.

However, in the conventional tube container, since the entire tube container or the tube head portion is made of synthetic resin, light or oxygen is introduced into the tube container, so that the contents contained in the tube container are easily deteriorated, resulting in poor quality. there was.

In order to solve this problem, a tubular cosmetic container has been disclosed with the Republic of Korea Utility Model No. 20-0375503, and the prior art is that a body whose one end is sealed is integrated with a shoulder having a discharge port through which the contents filled inside the body are discharged. In the tubular cosmetic container configured by being combined, a blocking member with a protruding fitting protrusion in the center is fitted to the inner side of the shoulder, and through this, it is possible to effectively block the transmission of oxygen from the shoulder portion, and inside the tubular cosmetic container. It is possible to extend the period of use by preventing deterioration of the filled contents.

However, in the prior art, the content flow path formed in the center of the blocking member is always open, and thus, light or oxygen flows into the body through the opened content flow path whenever the tubular cosmetic container is distributed and stored. Eventually, there was a structural limit in which the contents were deteriorated.

In addition, the prior art has a problem in that the operation for coupling the blocking member to the shoulder is inconvenient, resulting in an increase in manufacturing cost, resulting in a decrease in productivity. That is, in the prior art, after preparing a tubular cosmetic container, pushing the blocking member into the body of the tubular cosmetic container, the blocking member is continuously pushed so that the fitting protrusion of the blocking member inside the body is inhibited at the entrance of the discharge port. In addition, in order to securely fix the shoulder and the blocking member, there is an inconvenience of adding a process of fusion bonding the shoulder and the blocking member by applying an adhesive or applying heat to a portion that contacts each other.

A tube body in which the contents are accommodated, a tube head coupled to the tube body and formed with an inlet, and a blocking member containing a metal material by being inserted into the inlet of the tube head for a certain period to block the inflow of light or oxygen. A tubular cosmetic container with improved barrier properties of Example 1 was prepared to include.

Comparative example 1. Manufacture of aluminum tube

It was manufactured in the same size and shape as in Example 1, but an aluminum tube was manufactured by integrating the tube body and the tube head with an aluminum material. However, the blocking member was not included.

Comparative example 2. Poly foil Manufacture of tubes

It was manufactured in the same size and shape as in Example 1, but a polyfoil tube was manufactured by integrating the tube body and the tube head with a polyfoil (a sheet of PE material in which an aluminum foil fabric constitutes the center layer) material. However, the blocking member was not included.

Experimental example One. Barrier properties Experiment

A barrier property test was performed on the tubes of Example 1 and Comparative Examples 1 to 2. The experiment was conducted by injecting retinol contents into the tubes of Example 1 and Comparative Examples 1 to 2 and comparing the residual amount of the retinol active ingredient over time. Retinol is an ingredient sensitive to light, oxygen, temperature, etc., and the amount of active ingredient is greatly affected by the corresponding factors. The tube-type cosmetic container with improved barrier properties according to the present invention has a structure in which barrier properties to oxygen are improved, and in this experimental example, the effectiveness of the remaining amount of the active ingredient due to oxygen is verified. This experiment aims to preserve more than 90% of the initial active ingredient content.

First, the initial active ingredient content of the retinol content was measured and injected into the tube containers of Example 1 and Comparative Examples 1 to 2. Then, the tube containers of Example 1 and Comparative Examples 1 to 2 were placed in a thermostat at 40°C, and the change in the residual amount compared to the initial active ingredient was measured at intervals of 2 weeks. The results are shown in Table 1 and Fig. 9 by measuring the residual amount after 2 weeks, 4 weeks, and 8 weeks, based on the initial active ingredient content as 100%.

Initial retinol active ingredient content (%) Retinol active ingredient residual amount after 2 weeks (%) Retinol active ingredient residual amount after 4 weeks (%) Retinol active ingredient residual amount after 8 weeks (%) Example 1 100 98.8 95.7 91.8 Comparative Example 1 100 98.4 94.4 87.1 Comparative Example 2 100 95.3 90.3 78.8

As a result, it was confirmed that the tubular cosmetic container with improved barrier properties of Example 1 preserved 90% or more of the amount of the retinol active ingredient remaining after 2 weeks, 4 weeks, and 8 weeks. However, it was confirmed that the tube containers of Comparative Examples 1 and 2 maintained a residual amount of 90% until 2 weeks and 4 weeks, and showed a remarkably lower residual amount compared to the target value of 90% after 8 weeks elapsed. Through this, it was possible to confirm the high oxygen barrier properties of the tubular cosmetic container with improved barrier properties according to the present invention.

Accordingly, the tubular cosmetic container with improved barrier properties according to the present invention is a conventional aluminum tube and polyfoil through a coupling structure of a tube body, a tube head, and a blocking member attached to the inner side of the tube head by insert injection or double injection. The oxygen barrier property is increased compared to the tube.
