Description

Liquid content dispensing container with applicator

[0001] The present invention relates to a liquid content dispensing container, and more particularly, to a liquid content dispensing container equipped with an applicator through which liquid content is discharged to the outside by discharge pressure.

[0002] In today's modern society, people of all ages and genders are using cosmetics according to their needs in accordance with the rapidly diversifying trend of the times. In particular, women are using various types of cosmetics and cosmetics and tools with various colors, and through research and development by cosmetics companies, a variety of high-quality cosmetics and tools are being released to the market every day.

[0003] If we classify the above cosmetics by their purpose of use, they are classified into facial cleansing cosmetics used to remove sebum, waste products, and pollutants from the skin surface, basic cosmetics used to provide the skin with an appropriate amount of moisture and oil, color cosmetics used to express 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 and other substances to give off a scent to others.

[0004] Meanwhile, as living standards improve and interest in the safety of cosmetic compositions and skin beauty increases, many cosmetics are manufactured using natural ingredients. However, these cosmetics do not contain preservatives or other additives to minimize skin irritation, which makes them more susceptible to spoilage than cosmetics manufactured using chemical ingredients. For example, the cosmetics may become contaminated or spoiled when exposed to external air during use, resulting in bacterial infiltration or oxidation of the composition.

[0005] In addition, 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, but there has been an inconvenience in that the cosmetics must be taken out of the container with a spatula or fingers and applied to the skin or hair for use.

[0006] Accordingly, a tube container is being used that discharges cosmetics to the outside through changes in internal pressure due to pressurization of the container.

[0007] The above tube container is structured so that cosmetics contained inside the container are discharged to the outside through the discharge port of the nozzle as the user presses the soft container inward to change the internal pressure of the container. The tube container contains and stores a highly viscous gel-like substance inside and is composed of a tube body made of a soft material, a shoulder connected to the upper part of the tube body and having a discharge port formed therein, and a tube cap that opens and closes the discharge port.

[0008] However, the conventional tube container has a problem in that when the tube lid is opened, the outlet is open, allowing outside air or foreign substances to enter through the outlet, which contaminates or spoils the contents contained inside the tube container, and the contents discharged through the outlet must be rubbed with the user's hand to spread it widely on the skin, and then the cosmetics on the hand must be washed off, which is inconvenient to use and causes waste of the contents of the cosmetics.

[0009] To solve such a problem, a cosmetic application tip applied to a liquid cosmetic container was disclosed in Republic of Korea Utility Model Registration No. 20-0383301. The prior art comprises a rubber nozzle tip having at least one nozzle hole penetrating an inclined contact surface, a fixing tube that fixes the rubber nozzle tip and is assembled to the liquid cosmetic container, and a guide tube that is inserted and assembled inside the fixing tube and passes through a discharge passage for guiding liquid cosmetics to the rubber nozzle tip, and a structure in which a coupling ring groove and a coupling ring protrusion are formed on the rubber nozzle tip and the fixing tube, respectively, and are coupled by being fastened to each other.

[0010] However, since the above-mentioned conventional technology has a structure in which a rubber nozzle tip formed of a soft material wraps around a fixed pipe and is forcibly fastened, a work process of spreading the rubber nozzle tip and fastening it to the outside of the fixed pipe is added, which increases the manufacturing cost, and since it is not easy to perform such work, there is a problem in that the work speed decreases, and assembly defects occur, thereby lowering productivity.

[0011] In addition, the above-mentioned prior art had limitations in maintaining the adhesive force between the rubber nozzle tip and the fixed pipe due to the above-mentioned assembly structure. That is, when the soft rubber nozzle tip was deformed by an external force, the joint between the rubber nozzle tip and the fixed pipe was opened or misaligned, resulting in the inconvenience of use in which the rubber nozzle tip was easily separated from the fixed pipe.

[0012] Therefore, there is a need to develop a liquid content dispensing container that improves productivity and enhances the adhesion between the soft nozzle tip and the fixed tube.

[0015] Utility Model Registration No. 20-0383301 (announced on May 3, 2005)

[0016] In order to solve the above problems, the present invention aims to provide a liquid content dispensing container equipped with an applicator in which a soft applicator is double or insert injection-molded into a head integrally injection-molded with a tube, thereby simplifying the manufacturing process and increasing productivity, and in which the head and the applicator are stably attached to each other, thereby improving durability.

[0017] In order to achieve the above object, the present invention provides a liquid content dispensing container having an applicator including a tube in which a head is integrally injection-molded and a content is accommodated therein; a soft applicator formed by double injection or insert injection molding on the head and having a discharge port; and an overcap for opening and closing the applicator.

[0018] In addition, the head may have an inlet formed in the center, an inner wall formed on the outside of the inlet, and an outer wall formed on the outside of the inner wall of the head at a certain distance.

[0019] Additionally, the inner wall of the head is formed to be relatively longer than the outer wall of the head so that it can be inserted into the inside of the applicator.

[0020] Additionally, an insertion attachment groove may be formed between the head inner wall and the head outer wall, into which at least a portion of the applicator is inserted and attached.

[0021] In addition, the applicator may have an application surface provided on one side, and an outlet may be formed on the application surface.

[0022] In addition, the applicator may include a protrusion formed into the head, wherein the protrusion includes first to third sections that are bent to each other and come into contact with one surface of the head.

[0023] Additionally, the applicator may have an insertion space formed into which at least a portion of the head is inserted and which is connected to the inner space of the tube and the outlet of the applicator.

[0024] Additionally, the overcap may include a double sealing structure linked to the head and the applicator.

[0025] In addition, a sealing projection is formed on the above overcap to fit into the discharge port of the applicator, and a sealing side wall is formed on the outside of the sealing projection to wrap around the outer surface of the applicator and can be brought into close contact with the horizontal surface of the outer wall of the head and the horizontal surface of the outer surface of the applicator.

[0026] According to an embodiment of the present invention, the manufacturing process is simplified by omitting the separate assembly process of the head and the applicator, thereby reducing the production cost and increasing productivity as the production speed is increased.

[0027] According to an embodiment of the present invention, even if the soft applicator is elastically deformed by an external force, the attachment between the head and the applicator is stably maintained without being separated from the head, thereby improving durability.

[0028] According to an embodiment of the present invention, a double sealing structure is formed between the overcap, the applicator, and the head so that they are connected to each other, thereby more stably sealing the interior of the liquid content dispensing container.

[0040] Hereinafter, with reference to the attached drawings, a liquid content dispensing container equipped with an applicator according to an embodiment of the present invention will be described in detail.

[0041] 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 from above of a liquid content dispensing container according to an embodiment of the present invention, FIG. 3 is an exploded perspective view from below of a liquid content dispensing container according to an embodiment of the present invention, FIG. 4 is a cross-sectional view of a liquid content dispensing container according to an embodiment of the present invention, FIG. 5 is a cut-away perspective view showing a head of a liquid content dispensing container according to an embodiment of the present invention, FIG. 6 is a cut-away perspective view showing an applicator of a liquid content dispensing container according to an embodiment of the present invention, and FIG. 7 is a cut-away perspective view showing an overcap of a liquid content dispensing container according to an embodiment of the present invention.

[0042] As illustrated, a liquid content dispensing container equipped with an applicator according to an embodiment of the present invention may be configured to include a tube (10), an applicator (20), and an overcap (30).

[0043]

[0044] The liquid content dispensing container equipped with an applicator according to an embodiment of the present invention is described by dividing it into each component as follows.

[0045]

[0046] A storage space of a certain size is formed inside the above tube (10), and a liquid or gel-like content is stored in the storage space. The tube (10) is a storage body that discharges the content stored inside to the outside by changing its shape as the user applies pressure. The tube (10) is formed of a soft material so that its shape can be easily changed by the user's pressure, and may be formed of a thin synthetic resin material.

[0047] As shown in FIGS. 2 and 3, the tube (10) is preferably a streamlined shape with a width that gradually narrows from top to bottom, with the lower portion being sealed and the upper portion being open. Of course, the shape and material of the tube (10) are not limited to the above, and may be formed in various shapes or materials, taking into account the type of contents stored therein, usability, design elements, etc.

[0048] The above tube (10) is divided into a pressurizing portion (12) that is pressed by a user and a head (14) formed at one end of the pressurizing portion (12). The pressurizing portion (12) and the head (14) can have different degrees of deformation due to external force through differences in material or thickness. For example, the pressurizing portion (12) can be formed of a softer material or formed relatively thinly so that the pressurizing portion (12) can be easily deformed by external force, and the head (14) can be formed of a harder material or formed relatively thick so that the head (14) is not easily deformed by external force and maintains its shape. At this time, it is preferable that the pressurizing portion (12) and the head (14) are integrally injection-molded.

[0049] An applicator (20) is attached to one side of the head (14), and threads are formed on the outer periphery so that it can be detachably screw-connected to an overcap (30). As shown in Fig. 5, the head (14) has an inlet (14a) formed in the center, a head inner wall (14b) formed on the outside of the inlet (14a), and a head outer wall (14c) formed at a certain distance outside the head inner wall (14b). The inlet (22) is an inlet into which contents are filled during the manufacturing process of a liquid contents discharge container, and becomes a passage through which contents are moved by discharge pressure during the use process. The head inner wall (14b) and the head outer wall (14c) are ring-shaped protrusions extending from the head (14) in the direction of attachment of the applicator (20). The head inner wall (14b) is formed to be relatively longer than the head outer wall (14c) and is inserted into the inside of the applicator (20), thereby allowing the applicator (20) to be stably fixed to the head (14). At this time, it is preferable that the outer periphery of the head inner wall (14b) be formed to be inclined at a certain angle inward or outward as it goes toward the end.

[0050] Meanwhile, an insertion attachment groove (14d) may be formed between the head inner wall (14b) and the head outer wall (14c). The insertion attachment groove (14d) is a portion into which at least a portion of the applicator (20) is inserted and attached, and is formed to extend along the outer circumference of the head inner wall (14b) with a constant depth and width, thereby further expanding the contact area between the head (14) and the applicator (20).

[0051]

[0052] The above applicator (20) is formed on one side of the head (14) of the tube (10), and the contents contained inside the tube (10) are discharged, and the contents discharged in this way are used to apply them to the skin.

[0053] As shown in Fig. 6, an application surface (22) that directly contacts the user's skin is provided on one side of the applicator (20). The application surface (22) may be formed as a flat surface that is inclined at a certain angle from one end of the applicator (20) across the center to the opposite end, as shown in Fig. 6(a), or may be formed as a curved surface that becomes convex or concave as it goes toward the center of the applicator (20), or may be formed together with a flat inclined surface and a smooth curved surface each occupying a certain area. Of course, the application surface (22) is not limited to the above shape, and may be variously changed depending on the method of applying the liquid content and the convenience of use.

[0054] The above application surface (22) may be formed with a discharge port (22a) for discharging the contents contained in the tube (10) to the outside. The discharge port (22a) penetrates the applicator (20) and is connected to the internal space of the tube (10), and has an appropriate diameter considering the amount of contents to be discharged. In addition, at least one discharge port (22a) is formed, and may be formed in the center of the application surface (22) or may be formed offset to one side.

[0055] As shown in Fig. 4, the applicator (20) may be formed with a protrusion (24). The protrusion (24) is a part of the applicator (20) that is inserted into the insertion attachment groove (14d) of the head (14), and is formed to have a relatively larger diameter than other parts of the applicator (20) and protrudes outward, and the upper surface of the protrusion (24) is positioned on the same line as the upper end of the head outer wall (14c) of the head (14) and is naturally connected horizontally.

[0056] The above protrusion (24) may include a first section (24a) to a third section (24c) that are bent to each other and come into contact with one surface of the head (14). The first section (24a) comes into contact with the outer wall of the insertion groove (14d) formed in the head (14), the second section (24b) is bent from the first section (24a) and extends toward the center of the head (14) while coming into contact with the bottom surface of the insertion groove (14d) formed in the head (14), and the third section (24c) is bent from the second section (24b) and extends toward the end of the head (14) while coming into contact with the inner wall of the insertion groove (14d) formed in the head (14). As described above, the first section (24a) to the third section (24c) are in close contact with each other while surrounding the entire surface of the insertion attachment groove (14d) formed in the head (14), thereby expanding the contact area between the head (14) and the applicator (20), and accordingly, the adhesive force between the head (14) and the applicator (20) is increased, and the applicator (20) can be maintained in a state of being stably attached to the head (14).

[0057] An insertion space (26) may be formed in the above applicator (20). The insertion space (26) is a space provided on one side of the applicator (20), and connects the internal space of the tube (10) and the discharge port (22a) of the applicator (20), and the head inner wall (14b) of the head (14) is inserted into the insertion space (26).

[0058] The above applicator (20) is formed of an elastic material for a soft feel and ease of use, and is preferably formed of one or more materials of urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber), silicone, polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene) having elasticity, or TPE (Thermo Plastic Elastomer), which is a material between rubber and plastic and is soft and durable.

[0059] Meanwhile, the applicator (20) is formed integrally with the tube (10), and is double or insert injection-molded with the head (14) of the tube (10), so that productivity can be improved compared to conventional tube containers. Looking at the manufacturing process of the tube container, conventionally, a tube is extruded into a pipe type through an extruder, cut to a desired length, and then post-processing such as offset printing, silk printing, and coating is performed on the outer surface of the tube cut in this way, and then the post-processed tube is inserted and the head is injected, and then the applicator is separately injected and assembled to the head of the tube, etc., and several processes must be performed. However, the present invention can simplify the manufacturing process by injection-molding the tube (10) including the head (14), double injection-molding the applicator (20) on the head (14) of the tube (10), and then post-processing such as printing and coating is performed on the outer surface of the tube (10).

[0060] In addition, conventionally, a structure in which a soft applicator is undercut or forcibly connected to a head has been common. However, this type of connection structure has resulted in lower productivity during the manufacturing process and limitations in maintaining adhesive strength between the soft applicator and the head. In other words, conventionally, the assembly process of the head and the applicator has been added, which has increased manufacturing costs. In addition, since this assembly work, i.e., the work of undercutting or forcibly connecting a soft applicator to the head, has been difficult to perform, not only has the work speed decreased but also productivity has been reduced. In addition, when the soft applicator is deformed by an external force, the joint between the applicator and the head has become loose or misaligned, causing the applicator to easily separate from the head, which has resulted in usability inconvenience. Of course, these problems can be addressed by forming the applicator into a hard material, but the feel and usability have inevitably been inferior to those of a soft applicator.

[0061] To overcome such shortcomings, the liquid content dispensing container of the present invention is configured to simplify the manufacturing process by double or insert-molding a soft applicator (20) into a head (14) that is integrally injection-molded with a tube (10), thereby increasing productivity and stably attaching the head (14) and the applicator (20) to maintain durability.

[0062]

[0063] The above overcap (30) covers the applicator (20) to protect it from the outside, and has screw threads formed on the inner circumference so that it can be screw-connected with the screw threads formed on the head (14) of the tube (10). In the liquid content discharge container according to the embodiment of the present invention, the tube (10) and the overcap (30) are screw-connected to each other as an example, but it is not limited thereto, and various types of coupling structures such as undercut coupling, coupling of protrusions and grooves, or coupling by magnetic force can be used.

[0064] As shown in Fig. 4, the overcap (30) may include a double sealing structure connected to the head (14) and the applicator (20). A sealing projection (32) is formed on the overcap (30) to close the discharge port (22a) of the applicator (20), and at the same time, a sealing side wall (34) is formed to surround the applicator (20) and adhere to one surface of the head (14), and through this double sealing structure, the internal sealing of the tube (10) can be more stably maintained.

[0065] As shown in Fig. 7, the sealing projection (32) is formed to extend from the inner center of the overcap (30) toward the applicator (20) and is inserted into the discharge port (22a) of the applicator (20), and the sealing side wall (34) is formed to extend along the inner edge and is in close contact with the outer horizontal surface of the head (14) and the outer horizontal surface of the applicator (20). The sealing side wall (34) surrounds the outer side of the applicator (20) to protect the applicator (20), and it is preferable that the inner diameter of the sealing side wall (34) be formed to be equal to or relatively larger than the outer diameter of the applicator (20).

[0066] In addition, the sealing projection (32) and the sealing side wall (34) of the above overcap (30) can be closely connected to each other to perform a sealing function. When the sealing projection (32) is fitted into the discharge port (22a), the discharge port (22a) is forcibly opened, and the outward expansion of the soft applicator (20) is restricted by the sealing side wall (34), thereby minimizing the portion where the sealing function is reduced due to deformation of the applicator (20), and further strengthening the sealing force inside the tube (10).

[0067]

[0068] Hereinafter, with reference to the attached drawings, a method of using a liquid content dispensing container equipped with an applicator according to an embodiment of the present invention will be described.

[0069]

[0070] In order to use a liquid content dispensing container equipped with an applicator according to an embodiment of the present invention, the overcap (30) is separated from the tube (10) while releasing the fastening of the overcap (30). At this time, the double or insert injection-molded applicator (20) is opened in the head (14) of the tube (10), the sealing projection (32) of the overcap (30) comes out of the discharge port (22a) of the applicator (20), the discharge port (22a) is opened, and the sealing side wall (34) is separated from the head (14) and the applicator (20), so that the outer surface of the applicator (20) is exposed to the outside.

[0071] Thereafter, when the side of the tube (10) is pressed, discharge pressure is generated inside the tube (10), and the contents contained in the tube (10) pass through the inlet (14a) of the head (14) by the discharge pressure, and are then discharged to the application surface (22) through the discharge port (22a) of the applicator (20).

[0072] Thereafter, the contents discharged through the application surface (22) of the applicator (20) are applied to the skin by rubbing the application surface (22) on the skin. At this time, the applicator (20) is elastically deformed or bent to make soft contact with the skin, and is double or insert-molded with the head (14) to maintain a stable attachment state with the head (14).

[0073] After use, the applicator (20) is covered with the overcap (30) and combined with the head (14) of the tube (10) for storage or carrying. At this time, the sealing projection (32) of the overcap (30) is fitted into the discharge port (22a) of the applicator (20), and the sealing side wall (34) wraps around the applicator (20) and comes into close contact with the horizontal surface of the outer wall of the head (14) and the horizontal surface of the outer side of the applicator (20), so that the tube (10) is doubly sealed.

[0074]

[0075] As described above, although this description has been described with specific details such as specific components and limited embodiments and drawings, these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments, and those with ordinary skill in the art to which the present invention pertains can make various modifications and variations based on this description.
