One aspect of the present disclosure relates to a tube-type liquid discharging container, and more particularly, to a tube-type liquid discharging container in which a flow channel for contents is ensured through a double housing structure, and an opening and closing structure is formed on each of a tube body and a shoulder, so that a smooth discharge operation, stable sealing, and hygienic use are enabled.

BACKGROUND ART

Today, in modern society, according to the current of rapidly diversifying times, people of all ages and genders are using cosmetics according to their needs. In particular, women use various types of cosmetics, cosmetic products with various colors, tools, and the like, and various high-quality cosmetic products and tools are being released into the market every day through research and development of cosmetics-related companies.

When the cosmetics are classified according to their purpose of use, the cosmetics may be classified into facial cleansing cosmetics used to remove sebum, waste, and pollutants from a skin surface, basic cosmetics used to properly supply moisture and oil to the skin, color cosmetics used to express beautiful colors, hair cosmetics used to remove foreign substances from hair or scalp while protecting the hair and supplying nutrition to the hair, perfumes obtained by dissolving fragrances in alcohol and used to exude a scent to others, and the like.

Meanwhile, the cosmetics are frequently manufactured from natural raw materials as interest in safety of compositions of the cosmetics and skin beauty are increased due to the improvement of living standards. However, since preservatives and the like are not added to such cosmetics in order to minimize irritation to the skin, the cosmetics have a relatively high risk of deterioration as compared with cosmetics manufactured from chemical raw materials. For example, upon use, the cosmetics may be infiltrated by bacteria due to contact with external air, or the compositions of the cosmetics may be oxidized due to the contact with the air, so that contamination or deterioration of the cosmetics may be caused.

In addition, containers having a simple opening and closing function have been used to store and use cosmetics in liquid or gel forms, such as lotions, creams, gels, shampoos, and rinses, among the cosmetics. However, there was an inconvenience that the cosmetics have to be taken out from the container with a spatula or a finger and applied to the skin or hair for use.

Accordingly, tube containers that discharge cosmetics to an outside through a change in an internal pressure, which is caused by pressing of the containers, are being used.

The tube container has a structure in which the cosmetics accommodated in the container are discharged to the outside through a discharge port of a nozzle as a user presses a soft container inward to change the internal pressure of the container, and includes a tube body configured to contain and store a gel material having highly viscosity in the tube body and formed of a soft material, a shoulder coupled to an upper portion of the tube body and having a discharge port, and a tube lid configured to open and close the discharge port.

However, according to the tube container of the related art, the discharge port is opened when the tube lid is opened, so that external air or foreign substances may be introduced through the discharge port, which causes contamination or deterioration of contents accommodated in the tube container. In addition, even when an external force that pressed the tube container is removed, the contents may be continuously discharged by the internal pressure of the tube container, so that it may be difficult to control a discharge amount, which results in waste of the contents and insanitariness.

To solve such problems, Korean Utility Model Registration No. 20-0400310 has disclosed a valve device for a tube-type cosmetic container. According to the related art, a support body is coupled and installed to circumferentially form a discharge hole and a discharge gap at an inner center of a valve body, an insertion groove is formed at an upper center of the support body, and an elastic spring and a piston configured to receive elasticity by the elastic spring are inserted into the insertion groove, so that the piston is elastically pressed along with a pressure that presses a main body of a tube container to open and close a valve hole of the valve body.

However, the related art has a structure in which contents stored in the main body directly spread a gap between the piston and the valve body without passing through a housing while maintaining a high flow rate when the main body of the tube container is pressed, so that the contents may be suddenly popped out of the valve hole, which disables a smooth discharge operation and causes an inconvenience in use.

In addition, according to the relate art, after the main body of the tube container is pressed to discharge the contents through the valve hole, when a hand is removed from the main body to use the discharged contents, the discharged contents may be introduced back into the main body through the discharge port, so that contamination or deterioration of the entire contents inside the main body may be caused.

Therefore, there is a need to develop a tube-type liquid discharging container that enables a smooth discharge operation, stable sealing, and hygienic use.

Hereinafter, a tube-type liquid discharging container according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG.1is a perspective view showing a liquid discharging container according to an embodiment of the present disclosure,FIG.2is an exploded perspective view showing the liquid discharging container according to the embodiment of the present disclosure, andFIG.3is a sectional view showing the liquid discharging container according to the embodiment of the present disclosure.

As shown in the drawings, the tube-type liquid discharging container according to the embodiment of the present disclosure may include a tube body10, a shoulder20, an inner housing30, an opening and closing rod40, an elastic member50, an outer housing60, and a valve70.

The tube-type liquid discharging container according to the embodiment of the present disclosure will be described separately for each component as follows.

A storage space having a predetermined size may be formed inside the tube body10, and liquid or gel contents may be accommodated in the storage space. The tube body10may be a tube-type storage body having a shape that is deformed as a user presses the tube body10so that the contents accommodated in the tube body10may be discharged to an outside. The tube body10may be formed of a soft material so that the shape of the tube body10may be easily deformed by the pressing of the user, and formed of a synthetic resin material having a thin thickness, especially a polyethylene (PE) material. As shown inFIG.1, the tube body10may have a streamlined shape having a width that gradually narrows from a top to a bottom, and may preferably have a lower portion that is sealed and an upper portion that is opened. However, the shape and the material of the tube body10are not limited as described above, and the tube body10may be formed in various shapes or materials in consideration of a type of the contents stored in the tube body10, usability, design factors, or the like.

As shown inFIG.2, an inlet part12may be formed on an upper portion of the tube body10, that is, on an opposite side of the sealed portion, to discharge the contents stored in the tube body10, and a screw thread may be formed on an outer periphery of the inlet part12so as to be screw-coupled to the shoulder20. In this case, deformation degrees of the inlet part12and the remaining portion may become different from each other through relative thickness differences. In other words, the inlet part12may be formed relatively thick so that the inlet part12may maintain a shape of the inlet part12without being easily deformed by an external force, and the remaining portion may be formed relatively thin so that the remaining portion may be easily deformed by the external force of the user.

Meanwhile, a first one-way protrusion14may be formed on the outer periphery of the inlet part12of the tube body10. The first one-way protrusion14may be a component configured to restrict a rotation direction of the shoulder20with respect to the tube body10, the first one-way protrusion14may include a first inclined surface14aformed on the outer periphery of the inlet part12so as to be inclined in one direction and a first restriction sill14bprotruding perpendicularly from the outer periphery of the inlet part12, and first one-way protrusions14may be formed consecutively along a circumference of the inlet part12.

As shown inFIG.3, a sealing member16may be formed on an inner side of the tube body10. The sealing member16may be formed adjacent to the inlet part12to block oxygen or light from being introduced into the tube body10, and the sealing member16may be perforated by the outer housing60upon use of a tube container. The sealing member16may have one side that is closed and an opposite side that is opened so as to cover and block an inner side of the inlet part12of the tube body10. In other words, the sealing member16may have a cylindrical hat shape having a diameter that gradually increases from the closed portion to the opened portion and having a center that rises upward, and while the closed portion of the sealing member16is inserted toward the inlet part12of the tube body10, an edge portion of the sealing member16may make close contact with an inner periphery of the tube body10, so that airtightness of the inside of the tube body10may be maintained. In this case, the sealing member16may be preferably formed of a thin metal material such as aluminium.

Meanwhile, the sealing member16may be attached to the inner side of the tube body10in an insert injection or double injection scheme, or may be attached in a heat sealing scheme by melting the inner periphery adjacent to the inlet part12. In other words, after the sealing member16formed of the metal material is inserted into a molding space of a mold of the tube body10, a molten synthetic resin may be injected into the mold space to attach the tube body10to the sealing member16. In addition, an adhesive layer coated with an adhesive may be formed on a surface of the sealing member16to react with an injection temperature during injection molding of the tube body10, or an etching scheme (using chemicals to corrode a surface of a metal, ceramic, a semiconductor, or the like) may be applied to the surface of the sealing member16, so that the sealing member16formed of the metal material and the tube body10formed of the synthetic resin material may be easily attached to each other.

The shoulder20may be coupled to the inlet part12of the tube body10, and may have a discharge port22formed on one side of the shoulder20to discharge the contents stored in the tube body10to the outside. The shoulder20may preferably have a shape having an outer diameter that gradually decreases toward an end so as to have a sharp end in consideration of usability and design factors.

The shoulder20may be a discharge cap coupled to the inlet part12of the tube body10while surrounding the inlet part12of the tube body10, and configured to discharge the contents stored in the tube body10to the outside, and the inner housing30and the outer housing60may be formed in an inner space of the shoulder20. A coupling extension protrusion wheel23may be formed on an inner side of the shoulder20to extend downward, and fixedly coupled to an upper outer periphery of the inner housing30while surrounding the upper outer periphery of the inner housing30, and a screw thread may be formed on an inner periphery of the shoulder20so as to be screw-coupled to the screw thread formed on the outer periphery of the inlet part12of the tube body10.

As shown inFIG.2, a second one-way protrusion24may be formed on the inner periphery of the shoulder20to protrude inward so as to restrict the rotation direction of the shoulder20with respect to the tube body10together with the first one-way protrusion14formed on the tube body10. Similar to the first one-way protrusion14described above, the second one-way protrusion24may include a second inclined surface24aformed on the inner periphery of the shoulder20so as to be inclined in one direction and a second restriction sill24bprotruding perpendicularly from an outer periphery of the shoulder20, and second one-way protrusions24may be formed consecutively along a circumference of the inner periphery of the shoulder20. In other words, when the shoulder20is rotated in one direction, the shoulder20may rotate as the first inclined surface14aof the first one-way protrusion14rides over the second inclined surface24aof the second one-way protrusion24. However, when the shoulder20is rotated in an opposite direction, the first restriction sill14bof the first one-way protrusion14may be caught by the second restriction sill24bof the second one-way protrusion24, so that the shoulder20may not be rotated. Therefore, once the shoulder20is screw-coupled to the tube body10as the shoulder20is rotated in one direction, the shoulder20may not be rotated in the opposite direction due to the first one-way protrusion14and the second one-way protrusion24, so that the tube body10and the shoulder20may not be released from each other.

As shown inFIG.3, a lower extension protrusion wheel25may extend downward while being spaced apart from the outer periphery of the shoulder20by a predetermined distance. In this case, the lower extension protrusion wheel25may preferably extend further than a lower end of the shoulder20, and have the same diameter as the tube body10for design continuity.

A shoulder lid80configured to cover at least a portion of the shoulder20to protect the portion of the shoulder20from the outside may be further coupled to the shoulder20. A screw thread may be formed on an inner periphery of the shoulder lid80so as to be screw-coupled to the screw thread formed on the outer periphery of the shoulder20, and an end of the shoulder lid80may be seated on an upper end of the lower extension protrusion wheel25of the shoulder20. An airtight ring82may be formed on an inner side of the shoulder lid80, and the airtight ring82may protrude in a ring shape to make close contact with an outer end of the discharge port22of the shoulder20, so that when the shoulder20and the shoulder lid80are fastened to each other, airtightness of the discharge port22of the shoulder20may be more stably maintained by the airtight ring82. Although the shoulder20and the shoulder lid80have been shown in the drawings of the liquid discharging container according to the embodiment of the present disclosure as being screw-coupled to each other, embodiments are not limited thereto, and various types of coupling structures, such as undercut coupling, coupling of protrusions and grooves, or coupling by a magnetic force may be provided.

Meanwhile, a stopper90configured to restrict a downward movement of the shoulder20may be removably coupled to an outer lower end of the shoulder20. The stopper90may have a shape of a strip that surrounds an outer side of the inlet part12of the tube body10, and may be formed between the tube body10and the shoulder20to prevent the shoulder20from moving downward against intention of the user during distribution or storage. In this case, the stopper90may be detachably attached to the lower end of the shoulder20, and may be formed of a soft material so that the user may easily tear the stopper90off from the shoulder20. A handle92may be preferably formed on one side of the stopper90to protrude outward so that the user may easily pull and tear off the stopper90.

In addition, a shoulder cap26may be further coupled to an outer side of the shoulder20. In this case, the shoulder cap26may be preferably coupled to at least a portion of the shoulder20while surrounding the portion of the shoulder20, and formed of a thin metal material such as aluminium for visual effects or cooling sensations.

The inner housing30may be fixedly coupled to the inner space of the shoulder20. In other words, an upper portion of the inner housing30may be fitted into the coupling extension protrusion wheel23of the shoulder20so as to be undercut-coupled or forcibly fitted.

In other words, the elastic member50may be inserted into the opened portion of the inner housing30, and at least a portion of the opening and closing rod40may be inserted into the opened portion of the inner housing30so as to be seated on an end of the elastic member50, so that the opening and closing rod40may elastically perform a reciprocating movement in a predetermined region in a longitudinal direction of the inner housing30.

As shown in the partially enlarged view ofFIG.3, a contents inlet hole34configured to allow the contents stored in the tube body10to be introduced into an inner space of the inner housing30may be formed on one side of the inner housing30. In this case, a pair of contents inlet holes34may be preferably formed on the outer side of the inner housing30to ensure smooth introduction of the contents.

Meanwhile, a seating sill36may protrude from the outer side of the inner housing30, and the seating sill36may be seated on an upper end of the outer housing60to restrict an insertion region of the inner housing30into the outer housing60. In other words, the inner housing30may not be completely inserted into the outer housing60due to the seating sill36, and the outer housing60and the inner housing30may be spaced apart from each other by a predetermined distance, so that the contents may move through a gap between the outer housing60and the inner housing30.

The opening and closing rod40may be installed in the installation space32of the inner housing30, and may perform a reciprocating movement by a discharge pressure of the contents to temporarily open and close the discharge port22of the shoulder20. In this case, the opening and closing rod40may preferably have a cylindrical shape having a long length and a small width (diameter).

The opening and closing rod40may have one end inserted into or removed from the discharge port22to open and close the discharge port22, an opening and closing rod blade42may be formed on an outer periphery of the opening and closing rod40to make close contact with an inner periphery of the inner housing30, and the elastic member50may be inserted into the opening and closing rod blade42. In this case, it would be appropriate for the opening and closing rod blade42to perform a reciprocating movement between a bottom surface of the inner housing30and the contents inlet hole34by a distance at which the opening and closing rod blade42is pushed and moved by the discharge pressure of the contents.

The elastic member50may be installed in the installation space32of the inner housing30to elastically support the opening and closing rod40. In this case, the elastic member50may be preferably a compression spring (a spring that resists against a compressing force) formed of a metal material such as SUS-304.

The elastic member50may have one end making close contact with an inner bottom surface of the inner housing30and an opposite end making close contact with an end of the opening and closing rod40, and may provide elasticity to the opening and closing rod40.

The outer housing60may be fixedly coupled to at least a portion of the inner housing30while surrounding the portion of the inner housing30from outer side of the inner housing30. Although the inner housing30and the outer housing60have been shown in the drawings of the liquid discharging container according to the embodiment of the present disclosure as being undercut-coupled to each other, embodiments are not limited thereto, and various coupling structures that allow the outer housing60to be stably and fixedly coupled to the outer side of the inner housing30may be provided.

An insertion space62into which the inner housing30is inserted may be formed on an inner side of the outer housing60. In this case, an inner periphery of the outer housing60and the outer periphery of the inner housing30may be spaced apart from each other by a predetermined distance, and a flow channel66for the contents may be formed between the inner periphery of the outer housing60and the outer periphery of the inner housing30. In other words, as shown in the partially enlarged view ofFIG.3, when the inner housing30is inserted and coupled into the outer housing60, a predetermined space may be formed between an outer circumference of the inner housing30and an inner circumference of the outer housing60, and the formed space may become the flow channel66for stably moving the contents. In this case, the flow channel66may be connected to the contents inlet hole34of the inner housing30and the contents outlet64of the outer housing60.

Meanwhile, a perforation part68having a diagonal section may be formed in a lower portion of the outer housing60, that is, on an opposite side of the opened portion. The perforation part68may be a part for perforating the sealing member16formed in the tube body10, and a pair of perforation parts68may be preferably formed and arranged symmetrically to each other as shown inFIG.2. In other words, in order to use the liquid discharging container according to the present disclosure, when the stopper90is removed from the shoulder20, and the shoulder20from which the stopper90is removed is coupled to the tube body10, the inner housing30and the outer housing60may be inserted into the tube body10by a predetermined region as the shoulder20moves, so that the perforation part68of the outer housing60may pass through and perforate the sealing member16to open the inlet part12of the tube body10.

Meanwhile, a gasket65may be formed between the outer housing60and the tube body10to seal the inside of the tube body10. The gasket65may have a ring shape so as to be fitted around an outer side of the outer housing60. In this case, the gasket65may be formed of an elastic material to maintain airtightness between the outer housing60and the tube body10, the gasket65may be preferably formed of at least one material among urethane rubber, natural rubber, elastomer, nitrile-butadiene rubber (NBR), and silicone, polypropylene, or acrylonitrile butadiene styrene (ABS), and particularly, the gasket65may be most preferably formed of a polyethylene material having elasticity.

FIGS.4to8are views illustrating use of the tube-type liquid discharging container according to the embodiment of the present disclosure, and a method for using the tube-type liquid discharging container according to the embodiment of the present disclosure will be described with reference toFIGS.4to8.

FIG.4is a sectional view illustrating a state in which a stopper is removed from a shoulder according to the embodiment of the present disclosure,FIG.5is a sectional view illustrating a state in which the shoulder is rotated and coupled to a tube body according to the embodiment of the present disclosure,FIG.6is a sectional view illustrating a state in which a sealing is perforated as an outer housing is moved downward according to the embodiment of the present disclosure,FIG.7is a sectional view illustrating a state in which contents are discharged by pressing the tube body according to the embodiment of the present disclosure, andFIG.8is a sectional view illustrating a state in which the pressing of the tube body is released according to the embodiment of the present disclosure.

First, as shown inFIG.4, the shoulder lid80may be separated from the shoulder20, and the stopper90attached to an end of the shoulder20may be pulled and torn off from the shoulder20. In this case, the shoulder20and the tube body10may be spaced apart from each other by a height of the removed stopper90.

Next, as shown inFIG.5, when the shoulder20is rotated from the tube body10in one direction, the tube body10and the shoulder20may be coupled to each other so that the shoulder20may gradually move toward the tube body10, and simultaneously, the inner housing30and the outer housing60coupled to the inner side of the shoulder20may be gradually inserted into the inlet part12of the tube body10.

As shown inFIG.6, when the shoulder20is continuously rotated from the tube body10, the perforation part68of the outer housing60may pass through the sealing member16formed on the inner side of the tube body10to open the inlet part12of the tube body10. In this case, the contents outlet64of the outer housing60may be closed by the valve70, the discharge port22of the shoulder20may be closed by the opening and closing rod40, and airtightness of a gap between the tube body10and the outer housing60may be maintained by the gasket65.
