Description

[Technical Field]

[0001] The present invention relates to a tube-type liquid content dispensing container, and more particularly to a tube-type liquid content dispensing container that has a double housing structure to ensure a passage for the contents to move, and has opening and closing structures formed on the tube body and shoulder, respectively, to enable smooth dispensing operation, stable sealing, and hygienic use. [Background technology]

[0002] In today's modern society, people of all ages and genders use cosmetics as needed due to the rapid diversification of the times. In particular, women use a wide variety of cosmetics and cosmetic products and tools in a wide range of colors, and various high-quality cosmetic products and tools are sold on the market every day thanks to research and development by cosmetic-related companies.

[0003] The above cosmetics can be classified according to their intended use into cleansing cosmetics used to remove sebum, waste products, and pollutants from the surface of the skin, skin care cosmetics used to properly supply moisture and oil to the skin, color cosmetics used to create beautiful colors, hair cosmetics used to remove foreign substances from the hair or scalp while protecting and nourishing the hair, and perfumes used to dissolve fragrances in alcohol or other liquids to give others a scent.

[0004] Meanwhile, as interest in the stability of cosmetic compositions and skin care increases with the improvement of living standards, cosmetics are increasingly being produced from natural ingredients. These cosmetics do not contain preservatives to minimize skin irritation, and therefore have the disadvantage of being more susceptible to deterioration than cosmetics produced from chemical ingredients. For example, the cosmetics may be contaminated or deteriorated due to the penetration of bacteria or oxidation of the composition upon contact with air during use.

[0005] Furthermore, among the above cosmetics, containers with a simple opening and closing function have been used to store and use cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, and rinses. However, this has been inconvenient as users must take the cosmetics out of the container with a spatula or fingers and apply them to the skin or hair.

[0006] Therefore, tube-type cosmetic containers are used, which discharge cosmetics to the outside by changing the internal pressure when the container is pressed.

[0007] The tube container has a structure in which a user presses the soft container inward to change the internal pressure of the container, thereby discharging the cosmetic product contained inside the container to the outside through a nozzle outlet. The tube container includes a tube body made of a soft material that stores a highly viscous gel-like substance inside, a shoulder connected to the top of the tube body and having an outlet formed therein, and a tube cover that opens and closes the outlet.

[0008] However, the conventional tube container has a problem that the discharge port is open when the tube lid is opened, and external air or foreign matter flows into the discharge port, which can contaminate or deteriorate the contents stored inside the tube container. Also, even if the external force pressing the tube container is removed, the contents continue to be discharged due to the internal pressure of the tube container, making it difficult to control the discharge amount, which can result in waste of the contents and unhygienic problems.

[0009] To solve these problems, a valve device for a tube-type cosmetic container was disclosed in Korean Utility Model No. 20-0400310. In this prior art, a support is attached to and installed in the center of the valve body to form a discharge hole and a discharge gap on the circumference, and an insertion groove is formed in the center of the upper part of the support to insert a spring and a piston whose elasticity is provided by the spring. The piston is elastically pressed together with the pressure pressing the tube container body, opening and closing the valve hole of the valve body.

[0010] However, in the conventional technology, when the tube container body is pressed, the contents stored in the body directly expand the gap between the piston and the valve body while maintaining a high flow rate without passing through the housing, which causes the contents to suddenly jump out of the valve hole, making the dispensing operation difficult and inconvenient to use.

[0011] In addition, in the conventional technology, the tube container body is pressed to discharge the contents into the valve hole, and then the discharged contents are used. Therefore, the moment the user releases the body, the discharged contents flow back into the body through the discharge port, causing contamination or deterioration of the entire contents inside the body.

[0012] Therefore, there is a need to develop a tube-type liquid content dispensing container that allows for smooth dispensing operation, stable sealing, and hygienic use. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] Korean Registered Utility Model No. 20-0400310 (Announced on November 3, 2005) Summary of the Invention [Problem to be solved by the invention]

[0014] In order to solve the above problems, the present invention aims to provide a tube-type liquid content dispensing container that has a double housing structure consisting of an inner housing and an outer housing surrounding the inner housing, which ensures a passage for the contents to move, so that the contents can be smoothly discharged to the outside by opening and closing the discharge port through the passage between the inner and outer housings due to the discharge pressure.

[0015] In addition, the present invention aims to provide a tube-type liquid content dispensing container that can be used hygienically, by providing a valve in the outer housing that selectively opens and closes the content outlet, and forming an opening and closing rod in the inner housing that opens and closes the discharge port by elastically moving back and forth, and by such a double opening and closing structure, not only can the seal inside the tube body be stably maintained, but also. [Means for solving the problem]

[0016] In order to achieve the above-mentioned object, the present invention provides a tube-type liquid content dispensing container comprising: a tube body in which contents are stored and which has an inlet; a shoulder connected to the inlet of the tube body and which has a discharge port; an inner housing formed inside the shoulder and which has a contents inlet hole on one side; an opening / closing rod formed in the inner housing and which moves back and forth to open and close the discharge port; an elastic member which elastically supports the opening / closing rod; an outer housing connected to the inner housing while surrounding the outside of the inner housing and which has a contents outlet; and a valve provided at the contents outlet of the outer housing and which opens and closes the contents outlet, wherein the inner housing and the outer housing are spaced apart from each other by a predetermined distance to form a passageway for the contents to move between them.

[0017] A sealing member is formed inside the tube body to maintain airtightness inside the tube body, and is pierced by the outer housing.

[0018] The tube body may have a first unidirectional rotation protrusion, and the shoulder may have a second unidirectional rotation protrusion to restrict the rotation direction of the shoulder relative to the tube body.

[0020] In addition, a shoulder cap may be further attached to the outside of the shoulder, and the shoulder cap may be made of a metal material.

[0021] A stopper for restricting a lower movement of the shoulder is removably coupled to the shoulder.

[0022] In addition, a seating step is protruded from the outer side of the inner housing and seated on the upper end of the outer housing, so that the outer periphery of the inner housing and the inner periphery of the outer housing are spaced apart from each other.

[0023] In addition, the inner housing and the outer housing are inserted into the inside of the tube body by a certain distance as the shoulder moves when the tube body and the shoulder are coupled together.

[0024] The outer housing may have a lower portion formed with a perforation having a cross section in the shape of a diagonal line.

[0025] The passage may be connected to the content inlet of the inner housing and the content outlet of the outer housing.

[0026] In addition, the passage for the contents to move is secured through a double housing structure consisting of the inner housing and the outer housing surrounding the inner housing.

[0027] The discharge port of the shoulder and the content outlet of the outer housing are opened and closed by the opening and closing rod and the valve, respectively, thereby forming a double opening and closing structure before and after the moving passage. [Effects of the Invention]

[0028] According to an embodiment of the present invention, a passage for the contents is secured through a double housing structure consisting of an inner housing and an outer housing surrounding the inner housing, and thereby the contents are smoothly discharged to the outside by opening and closing the discharge port through the passage between the inner and outer housings according to the discharge pressure.

[0029] According to an embodiment of the present invention, a valve that selectively opens and closes the content outlet is provided in the outer housing, and an opening and closing rod that opens and closes the discharge port by elastically moving back and forth is formed in the inner housing.

Therefore, the terms used in the present invention should not be simply defined by their names, but should be defined based on the meanings of the terms and the overall content of the present invention.

[0034] In the present invention, when a part "comprises" a certain component, this does not mean that other components are excluded, and means that other components may also be included, unless otherwise specified.

[0035] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a tube-type liquid content dispensing container according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0036] FIG. 1 is a perspective view of a liquid content dispensing container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a liquid content dispensing container according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view of a liquid content dispensing container according to an embodiment of the present invention.

[0037] As shown in the figure, the tube-type liquid content dispensing container according to an embodiment of the present invention may be configured to include a tube body 10, a shoulder 20, an inner housing 30, an opening and closing rod 40, an elastic member 50, an outer housing 60, and a valve 70.

[0038] The tube-type liquid content dispensing container according to the embodiment of the present invention will be described below in terms of each component.

[0039] The tube body 10 has a storage space of a certain size formed therein, and liquid or gel content is stored in the storage space. The tube body 10 is a tube-type storage body that is deformed by being pressed by a user to discharge the stored content to the outside, and is formed of a soft material so that its shape can be easily deformed by being pressed by a user. It may be formed of a thin synthetic resin material, particularly a PE (Polyethyl Ene) material. As shown in FIG. 1, the tube body 10 preferably has a streamlined shape that gradually narrows from top to bottom, and is sealed at the bottom and open at the top. Of course, the shape and material of the tube body 10 are not limited to those described above, and may be formed of various shapes and materials depending on the type of content stored therein, usability, design elements, etc.

[0040] 2, an inlet 12 is formed at the top of the tube body 10, i.e., on the opposite side of the sealed portion, to discharge the contents stored inside the tube body 10. The inlet 12 may have a thread formed on its outer periphery to be threadedly coupled to a shoulder 20. Here, the inlet 12 and the remaining portions may have different degrees of deformation due to differences in relative thickness. That is, the inlet 12 may be formed relatively thick to prevent the inlet 12 from being easily deformed by external force while maintaining its shape, and the remaining portions may be formed relatively thin to allow it to be easily deformed by external force from the user.

[0041] Meanwhile, a first unidirectional protrusion 14 may be formed on the outer circumferential edge of the inlet portion 12 of the tube body 10. The first unidirectional protrusion 14 may be configured to limit the rotation direction of the shoulder 20 relative to the tube body 10 and may include a first inclined surface 14a formed on the outer circumferential edge of the inlet portion 12 and inclined in one direction, and a first limiting step 14b protruding perpendicularly from the outer circumferential edge of the inlet portion 12, and may be formed continuously along the periphery of the inlet portion 12.

[0042] As shown in FIG. 3, a sealing member 16 may be formed inside the tube body 10. The sealing member 16 is formed adjacent to the inlet 12 to prevent oxygen or light from entering the tube body 10 and may be pierced by the outer housing 60 when the tube container is in use. The sealing member 16 has one closed side and the other open side, covering and sealing the inside of the inlet 12 of the tube body 10. That is, the sealing member 16 has a cylindrical hat shape with a protruding center and a diameter that gradually increases from the closed portion to the open portion. When the closed portion of the sealing member 16 is inserted toward the inlet 12 of the tube body 10, its rim is tightly attached to the inner periphery of the tube body 10, maintaining the interior of the tube body 10 airtight. The sealing member 16 is preferably made of a thin metal material such as aluminum.

[0043] Meanwhile, the sealing member 16 may be attached to the inside of the tube body 10 by an insert injection or double injection method, or by a heat sealing method by melting the inner periphery adjacent to the inlet 12. That is, the metal sealing member 16 is inserted into the mold cavity of the mold for the tube body 10, and then molten synthetic resin is injected into the mold cavity to attach the tube body 10 and the sealing member 16. Alternatively, an adhesive layer may be formed on the surface of the sealing member 16 to react with the injection temperature during injection molding of the tube body 10, or an etching method (etching the surface of metals, ceramics, semiconductors, etc. using chemicals) may be applied to the surface of the sealing member 16 to facilitate attachment of the metal sealing member 16 and the synthetic resin tube body 10 to each other.

[0044] The shoulder 20 is connected to the inlet 12 of the tube body 10 and has a discharge port 22 formed on one side thereof to discharge the contents stored in the tube body 10 to the outside. In consideration of usability and design, the shoulder 20 is preferably formed in a pointed shape with an outer diameter that gradually decreases toward the end.

[0045] The shoulder 20 is coupled to the inlet 12 of the tube body 10 while surrounding it, and an inner housing 30 and an outer housing 60 may be formed in its inner space as a discharge cap for discharging the contents stored in the tube body 10 to the outside. A coupling extension ring 23 is formed on the inside of the shoulder 20 and extends downward to surround and securely couple to the upper outer periphery of the inner housing 30, and a screw thread may be formed on the inner periphery to be screwed into the screw thread formed on the outer periphery of the inlet 12 of the tube body 10.

[0046] 2, a second unidirectional protrusion 24 is formed on the inner peripheral edge of the shoulder 20 to protrude inward and, together with the first unidirectional protrusion 14 formed on the tube body 10, limit the rotation direction of the shoulder 20 relative to the tube body 10. Similar to the first unidirectional protrusion 14 described above, the second unidirectional protrusion 24 may be formed continuously around the inner peripheral edge of the shoulder 20, including a second inclined surface 24a formed on the inner peripheral edge of the shoulder 20 inclined in one direction and a second limiting step 24b protruding perpendicularly from the outer peripheral edge. That is, when the shoulder 20 is rotated in one direction, the first inclined surface 14a of the first unidirectional protrusion 14 rides over the second inclined surface 24a of the second unidirectional protrusion 24, thereby rotating the shoulder 20. However, when the shoulder 20 is rotated in the opposite direction, the first limiting step 14b of the first unidirectional protrusion 14 engages with the second limiting step 24b of the second unidirectional protrusion 24, preventing the shoulder 20 from rotating. Therefore, once the shoulder 20 is screwed to the tube body 10 while being rotated in one direction, it cannot be rotated in the opposite direction due to the first unidirectional protrusion 14 and the second unidirectional protrusion 24, and the tube body 10 and the shoulder 20 cannot be released again.

[0047] 3, a lower extension ring 25 may be formed extending downward at a predetermined distance from the outer periphery of the shoulder 20. Here, the lower extension ring 25 is preferably formed extending further than the lower end of the shoulder 20 and having the same diameter as the tube body 10 for design continuity.

[0048] A shoulder cover 80 may be further coupled to the shoulder 20 to cover at least a portion of the shoulder 20 and protect it from the outside. The shoulder cover 80 may have a thread formed on its inner periphery for threaded engagement with the thread formed on the outer periphery of the shoulder 20, and an end of the shoulder cover 80 may be seated on the upper end of the lower extension ring 25 of the shoulder 20. An airtight ring 82 is formed on the inside of the shoulder cover 80. The airtight ring 82 is formed in a ring shape and is tightly fitted to the outer end of the outlet 22 of the shoulder 20. Therefore, when the shoulder 20 and the shoulder cover 80 are fastened together, the outlet 22 of the shoulder 20 can be more stably maintained airtight by the airtight ring 82. In the drawings of the liquid content dispensing container according to the embodiment of the present invention, the shoulder 20 and the shoulder cover 80 are illustrated as being threadedly coupled together, but the present invention is not limited thereto and various coupling structures may be used, such as an undercut coupling, a protrusion and groove coupling, or a magnetic coupling.

[0049] Meanwhile, a stopper 90 for restricting downward movement of the shoulder 20 may be removably attached to the outer lower end of the shoulder 20. The stopper 90 is a strip-shaped stopper that surrounds the outside of the inlet 12 of the tube body 10 and is formed between the tube body 10 and the shoulder 20 to prevent the shoulder 20 from moving downward unintentionally during distribution or storage. The stopper 90 is detachably attached to the lower end of the shoulder 20 and is made of a soft material so that the user can easily remove it from the shoulder 20. Preferably, a tab 92 is formed protruding outward from one side of the stopper 90 so that the user can easily pull and remove the stopper 90.

[0050] A shoulder cap 26 may be further attached to the outside of the shoulder 20. At this time, the shoulder cap 26 is attached while surrounding at least a portion of the shoulder 20, and is preferably made of a thin metal material such as aluminum for visual effect or cooling sensation.

[0051] The inner housing 30 is fixedly coupled to the inner space of the shoulder 20. That is, the upper part of the inner housing 30 may be undercut or forcedly fitted into the inner space of the coupling extension ring 23 of the shoulder 20.

[0052] The inner housing 30 serves as a temporary storage space for the contents, and has a cylindrical shape with one side open and the other closed, forming an installation space 32 inside thereof, in which an elastic member 50 and an open-close rod 40 may be installed along the direction of discharging the contents. That is, the elastic member 50 is inserted into the open part of the inner housing 30, and at least a portion of the open-close rod 40 is inserted and seated on an end of the elastic member 50, so that the open-close rod 40 can elastically reciprocate within a certain range along the longitudinal direction of the inner housing 30.

[0053] 3, one side of the inner housing 30 may be formed with a content inlet hole 34 for allowing the content stored in the tube body 10 to flow into the inner space of the inner housing 30. In this case, it is preferable that a pair of content inlet holes 34 are formed on the outer side of the inner housing 30 to ensure smooth inflow of the content.

[0054] Meanwhile, a seating step 36 may be protruded from the outside of the inner housing 30. The seating step 36 is seated on the upper end of the outer housing 60 to limit the insertion distance of the inner housing 30 into the outer housing 60. In other words, the seating step 36 may prevent the inner housing 30 from being completely inserted into the outer housing 60, and may cause a certain gap between the outer housing 60 and the inner housing 30, allowing the contents to move into the gap.

[0055] The opening / closing rod 40 is installed in the installation space 32 of the inner housing 30 and moves back and forth depending on the discharge pressure of the contents to temporarily open and close the discharge port 22 of the shoulder 20. At this time, the opening / closing rod 40 is preferably formed in a cylindrical shape with a long length and a small width (diameter).

[0056] The open-close rod 40 opens and closes the discharge port 22 by inserting one end into or removing it from the discharge port 22, and may have an open-close rod blade 42 formed on its outer periphery to be in close contact with the inner periphery of the inner housing 30, with an elastic member 50 inserted inside the open-close rod blade 42. Here, it is preferable that the open-close rod blade 42 reciprocates between the bottom surface of the inner housing 30 and the contents inlet hole 34 by an amount corresponding to the amount of movement while being pushed by the discharge pressure of the contents.

[0057] The elastic member 50 is installed in the installation space 32 of the inner housing 30 to elastically support the open / close bar 40. At this time, the elastic member 50 is preferably a compression spring (a spring that resists compressive force) made of a metal material such as SUS-304.

[0058] The elastic member 50 has one end closely contacted to the inner bottom surface of the inner housing 30 and the other end closely contacted to the end of the opening / closing bar 40 to provide elasticity to the opening / closing bar 40 .

[0059] The outer housing 60 is fixedly coupled to the inner housing 30 while surrounding at least a portion of the inner housing 30. In the drawings of the liquid content dispensing container according to the embodiment of the present invention, the inner housing 30 and the outer housing 60 are shown as being undercut coupled to each other, but the present invention is not limited thereto, and various coupling structures may be used as long as the outer housing 60 is stably and firmly coupled to the outer side of the inner housing 30.

[0060] The outer housing 60, together with the inner housing 30, serves as a temporary storage space for the contents, and a contents outlet 64 through which the contents stored in the tube body 10 pass may be formed at the bottom of the outer housing 60, and a valve 70 may be provided at the contents outlet 64 to selectively open and close the contents outlet 64.

[0061] An insertion space 62 into which the inner housing 30 is inserted may be formed inside the outer housing 60. At this time, the inner periphery of the outer housing 60 and the outer periphery of the inner housing 30 are spaced apart by a predetermined distance, forming a passageway 66 for the contents therebetween. In other words, as shown in the partially enlarged view of FIG. 3 , when the inner housing 30 is inserted and coupled into the outer housing 60, a predetermined space is formed between the outer periphery of the inner housing 30 and the inner periphery of the outer housing 60, and this formed space serves as the passageway 66 for the stable movement of the contents. At this time, the passageway 66 may be connected to the contents inlet 34 of the inner housing 30 and the contents outlet 64 of the outer housing 60.

[0062] Meanwhile, a perforation portion 68 having a diagonal cross section may be formed at the bottom of the outer housing 60, i.e., on the side opposite the open portion. The perforation portion 68 is a portion for opening the sealing member 16 formed on the tube body 10, and is preferably formed in a pair and arranged symmetrically with each other, as shown in Fig. 2. That is, to use the liquid contents dispensing container of the present invention, the stopper 90 is removed from the shoulder 20, and the shoulder 20 from which the stopper 90 has been removed is coupled to the tube body 10. As the shoulder 20 moves, the inner housing 30 and the outer housing 60 are inserted into the tube body 10 by a certain distance, and thus the perforation portion 68 of the outer housing 60 penetrates and opens the sealing member 16, thereby opening the inlet portion 12 of the tube body 10.

[0063] Here, the inner housing 30, the opening / closing bar 40, and the outer housing 60 are made of a thermosetting resin or a thermoplastic resin, and the thermosetting resin is preferably made of one or more of epoxy resin, amino resin, phenol resin, and polyester resin, and the thermoplastic resin is preferably made of one or more of polyethylene, acrylic resin, polypropylene, polystyrene, polyvinyl chloride, Teflon, nylon, and polyacetal resin, and most preferably made of polypropylene. Of course, the inner housing 30, the opening / closing bar 40, and the outer housing 60 are not limited to the above materials and may be made of various other materials.

[0064] Meanwhile, a gasket 65 is formed between the outer housing 60 and the tube body 10 to seal the inside of the tube body 10. The gasket 65 may be formed in a ring shape and be sandwiched on the outside of the outer housing 60. In this case, the gasket 65 is made of an elastic material to maintain airtightness between the outer housing 60 and the tube body 10, and is preferably made of one or more of urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber), silicone, polypropylene, or ABS (Acrylonitrile Butadiene Styrene), and most preferably made of an elastic polyethylene material.

[0065] The valve 70 is provided at the content outlet 64 of the outer housing 60 to open and close the content outlet 64. Here, the valve 70 is preferably a disc valve formed in a disk shape that is lifted up and restored by the internal pressure of the tube body 10 to selectively open and close the content outlet 64.

[0066] As discussed above, the tube-type liquid content dispensing container according to the embodiment of the present invention secures a passageway 66 for the contents through a double housing structure consisting of the inner housing 30 and the outer housing 60 surrounding the inner housing 30, and forms a double opening and closing structure between the outer housing 60 and the discharge port 22. This not only allows the contents to be smoothly discharged to the outside through the passageway 66 by opening and closing the discharge port 22 due to the discharge pressure, but also prevents contamination of the contents stored in the tube body 10 and enables hygienic use of the tube container.

[0067] 4 to 8 are diagrams illustrating the use of a tube-type liquid content dispensing container according to an embodiment of the present invention, and a method of using the tube-type liquid content dispensing container according to an embodiment of the present invention will be described with reference to these figures.

[0068] FIG. 4 is a cross-sectional view illustrating an example of removing a stopper from a shoulder according to an embodiment of the present invention, FIG. 5 is a cross-sectional view illustrating an example of rotating a shoulder according to an embodiment of the present invention to couple with a tube body, FIG. 6 is a cross-sectional view illustrating an example of piercing a sealing member as an outer housing according to an embodiment of the present invention moves downward, FIG. 7 is a cross-sectional view illustrating an example of pressing a tube body according to an embodiment of the present invention to discharge the contents, and FIG. 8 is a cross-sectional view illustrating an example of releasing the pressure on a tube body according to an embodiment of the present invention.

[0069] First, as shown in Figure 4, the shoulder cover 80 is separated from the shoulder 20, and the stopper 90 attached to the end of the shoulder 20 is pulled to remove it from the shoulder 20. At this time, the shoulder 20 and the tube body 10 are spaced apart by the height of the removed stopper 90.

[0070] Then, as shown in FIG. 5, when the shoulder 20 is rotated in either direction from the tube body 10, the tube body 10 and the shoulder 20 are coupled together, and the shoulder 20 gradually moves toward the tube body 10. At the same time, the inner housing 30 and the outer housing 60 coupled to the inside of the shoulder 20 are gradually inserted into the inlet portion 12 of the tube body 10.

[0071] 6, as the shoulder 20 continues to rotate from the tube body 10, the perforated portion 68 of the outer housing 60 penetrates and opens the sealing member 16 formed inside the tube body 10, thereby opening the inlet portion 12 of the tube body 10. At this time, the content outlet 64 of the outer housing 60 is closed by the valve 70, the discharge port 22 of the shoulder 20 is closed by the opening / closing rod 40, and the gap between the tube body 10 and the outer housing 60 is maintained airtight by the gasket 65.

[0072] 7, when the side of the tube body 10 is pressed, pressure is generated inside the tube body 10, and the contents contained in the tube body 10 are discharged through the discharge port 22 of the shoulder 20 by the discharge pressure. More specifically, the discharge pressure of the contents pushes up the valve 70, opening the contents outlet 64 of the outer housing 60, and the contents passing through the contents outlet 64 flow into the inner space of the inner housing 30 through the contents inlet hole 34 of the inner housing 30 via the transfer passage 66 between the inner housing 30 and the outer housing 60. Subsequently, the discharge pressure of the contents pushes the opening / closing rod 40 backward, separating the end of the opening / closing rod 40 from the discharge port 22 of the shoulder 20, opening the discharge port 22, and simultaneously discharging the contents through the discharge port 22 to the outside.

[0073] Thereafter, as shown in FIG. 8, when the pressure on the side of the tube body 10 is released, the discharge pressure is released and the open / close rod 40 is restored to its original shape by the elastic restoring force of the elastic member 50, thereby closing the discharge port 22 of the shoulder 20, and at the same time, the valve 70 is restored to its original shape, thereby closing the contents outlet 64 of the outer housing 60.

[0074] After use, the shoulder lid 80 is attached to the shoulder 20 and stored or carried.
