Automatic filling dropper-type cosmetic container

Abstract

The present invention relates to an automatically filling dropper-type cosmetic container, and when the cap (300) is turned in the opposite direction and gradually opened, the bracket (400) and the piston support member (500) rise from the container body (100), and the piston (600) rises a certain distance until it comes into contact with the bushing member (800) while being in close contact with the wall surface of the cylinder portion (710), generating suction pressure inside the cylinder portion (710) of the dropper tube (700). The generated suction pressure causes a portion of the content (cosmetic liquid) in the container body (100) to be sucked into the suction member (720) of the dropper tube (700) through the communication hole (730), automatically filling the container.

Description

【Technical Field】 【0001】 The present invention relates to an automatic filling type spatula-shaped cosmetic container, and more particularly to an "automatic filling type spatula-shaped cosmetic container" that can automatically fill the spatula tube with the content (cosmetic liquid) during the process of turning and opening the cap with respect to the container body, thereby further improving the convenience of use. 【Background Art】 【0002】 In recent years, the demand for functional cosmetics for maintaining youth, preventing aging due to environmental pollution, improving wrinkles, and blocking ultraviolet rays has been increasing rapidly. Since functional cosmetics are very vulnerable to external contamination, when applying the content by hand like general cream-type cosmetics, or when discharging the content after approaching the opening of the container to the palm like lotion-type cosmetics, there is a risk that contaminants from the hand will penetrate into the inside of the cosmetic container and deteriorate the content. Therefore, some functional cosmetics use spatula-shaped cosmetic containers. A spatula-shaped cosmetic container can prevent deterioration during the process of dispensing the content (cosmetic liquid), and can take out a fixed amount of the content and accurately supply it to the target site, thus preventing waste of cosmetics. 【0003】 FIG. 1 is a cross-sectional view showing a conventional spatula-shaped cosmetic container. Referring to FIG. 1, a conventional spatula-shaped cosmetic container includes a container body 11 that houses the content (cosmetic liquid) inside, a cap portion 12 that can open and close the opening of the container body 11, a pressing portion 13 made of an elastic material provided on the upper part of the cap portion 12 that causes a pressure change, and a spatula tube 14 formed to extend downward from the pressing portion 13 and suck and discharge the content housed in the container body 11. Such a conventional spatula-shaped cosmetic container has to be used by immersing the spatula tube 14 in the content in the container body 11, pressing the pressing portion 13, and then separating the cap portion 12 from the container body 11. Thus, the conventional spatula-shaped cosmetic container has a problem in that its use is troublesome because the content has to be sucked in by manually pressing the pressing portion 13 every time it is used. 【Summary of the Invention】 [Problems that the invention aims to solve] 【0004】 The present invention aims to solve these problems, and its objective is to provide an "automatic filling dropper-type cosmetic container" that can further improve the convenience of use by automatically filling a portion of the contents (cosmetic liquid) into the dropper tube during the process of opening the cap by turning it in the opposite direction on the container body containing the contents. [Means for solving the problem] 【0005】 To achieve the above objectives, the present invention provides a container body that contains contents and has a screw-type neck at the top; a wiper that is inserted and connected to the neck of the container body in an interference fit manner and has a through hole drilled at the bottom; a cap that is connected to the neck of the container body so as to be able to open and close by rotating in forward and reverse directions and has an elastic material pusher at the top that can generate air pressure by pressing operation; and a coupling that is inserted and connected coaxially inside the cap in an interference fit manner, and has a central part that communicates with the inside of the pusher and extends downward. A bracket with a fitting formed on it, a piston support member whose upper end is inserted into and connected to the fitting of the bracket in an interference fit manner and communicates with the pusher, whose lower end extends downward and has an air hole perforated on its side, a piston positioned at the lower end of the piston support member and positioned higher than the air hole and surrounding the outer casing of the piston support member, and a component which houses and connects the piston support member and the piston so as to be vertically movable inside the wiper and positions the cap in the forward direction relative to the neck of the container body A pipette tube equipped with a suction member that, when turned to close, causes the piston to descend together with the piston support member, and when the cap is turned to open in the opposite direction relative to the neck of the container body, causes the piston to rise together with the piston support member and generate suction force; a pipette tube equipped with a suction member that extends in a pipe shape from the lower center of the cylinder part, passes through the through hole of the wiper in a tight seal and is housed in the container body, and when suction force is generated in the cylinder part, sucks up and stores a portion of the contents in the container body, and when the pusher is pressed, generates air pressure and discharges the stored contents, with a flow hole perforated at the lower end; a bushing member that is joined to the uppermost end of the cylinder part of the pipette tube by interference fit, and prevents the piston support member and the piston from separating from the cylinder part of the pipette tube while allowing the upward movement of the piston support member and the piston for a certain distance during the process of turning the cap to open in the opposite direction relative to the neck of the container body; and provided between the wiper and the cylinder part of the pipette tube.The device is characterized by including a grooved interlocking member that, in the process of opening the cap by turning it in the opposite direction to the neck of the container body, maintains the cylinder portion of the dropper tube housed inside the wiper and connected until the piston support member and the piston rise and contact the bushing member. 【0006】 Furthermore, according to the present invention, the interlocking member is characterized by including an interlocking groove formed in a circumferential concave shape on the inner wall of the wiper, and an interlocking projection that protrudes in a strip shape along the outer wall of the cylinder portion of the dropper tube, and which interlocks with the interlocking groove in an interlocking manner when the cap is completely rotated to close the neck of the container body, thereby temporarily fixing the dropper tube in position on the wiper. [Effects of the Invention] 【0007】 According to the "automatic filling dropper-type cosmetic container" of the present invention, which has the above configuration, when the cap is turned in the reverse direction and gradually opened, the bracket and piston support member rise from the container body, and so the piston rises for a certain distance until it contacts the bushing member while in close contact with the wall surface of the cylinder part, thereby generating suction pressure inside the cylinder part of the dropper tube. Due to the suction pressure generated inside the cylinder part, a portion of the contents (cosmetic liquid) in the container body is drawn into the suction member of the dropper tube through the flow hole and automatically filled. In other words, suction pressure is generated in the cylinder part during the process of removing the dropper tube by turning the cap in the reverse direction relative to the container body, and so the contents (cosmetic liquid) are automatically filled (drawn in) into the suction member of the dropper tube, which has the advantage of being more convenient to use.

[Modes for carrying out the invention] 【0009】 A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. To briefly explain the attached drawings, Figures 2 to 4 show the configuration of the dropper-type cosmetic container according to the present invention, and Figures 5 to 10 show the state of use of the dropper-type cosmetic container according to the present invention. 【0010】 <Description of the configuration of the self-filling dropper-type cosmetic container according to the present invention> The self-filling dropper-type cosmetic container according to the present invention is designed so that a portion of the contents (cosmetic liquid) is automatically filled into the dropper tube when the cap is turned in the opposite direction to open the container body containing the contents. As shown in Figures 2 and 3, the container body 100 contains the contents (cosmetic liquid) A, a wiper 200 is connected to the neck 110 of the container body 100 and has a through hole 210 perforated at the bottom, a cap 300 is connected to the neck 110 of the container body 100 so as to be openable and closable and has a pusher 310 positioned on top, a bracket 400 is positioned coaxially inside the cap 300, a piston support member 500 is connected coaxially inside the bracket 400 and has a piston 600 positioned on its outer circumference, and a cylinder portion 710 and inner portion house the piston 600 together with the piston support member 500. The present invention includes a dropper tube 700 composed of a suction member 720 that can suck in and store contents by internal pressure or discharge contents to the outside; a bushing member 800 that is joined to the uppermost end of the cylinder portion 710 of the dropper tube 700 in an interference fit manner and, together with a piston support member 500, prevents the piston 600 from coming out of the cylinder portion 710 of the dropper tube 700; and a grooved interlocking member 900 provided between the wiper 200 and the cylinder portion 710 of the dropper tube 700, which maintains the cylinder portion 710 of the dropper tube 700 housed inside the wiper 200 and joined until the piston support member 500 and the piston 600 rise and come into contact with the bushing member 800 during the process of opening the cap 300 by turning it in the opposite direction to the neck 110 of the container body 100. Most of the components of the cosmetic container according to the present invention are injection molded from synthetic resin, and a specific description of the material is omitted. 【0011】 Referring to Figures 2 and 3, the container body 100 of the cosmetic container according to the present invention is formed in a cylindrical shape to house contents inside, and is equipped with a screw-type neck 110 at its upper part. 【0012】 The wiper 200 is then inserted and joined to the neck 110 of the container body 100 using an interference fit method, and a through hole 210 with an inner diameter matching the diameter of the suction member 720 of the dropper tube 700 is drilled at the bottom. The wiper 200 plays a role in thoroughly washing away the contents A attached to the outer wall of the suction member 720 of the dropper tube 700 as it exits the container body 100. 【0013】 Referring to Figures 3 and 4, the cap 300 is connected to the neck 110 of the container body 100 so that it can be opened and closed by rotating in forward and reverse directions, and is equipped with an elastic pusher 310 on its upper part that can generate air pressure by pressing. The pusher 310 is rigidly integrated with the upper part of the cap 300 via a shoulder member 320. 【0014】 The bracket 400 is formed in a cylindrical shape and is inserted into the cap 300 by an interference fit to connect them. A connector 410 is formed in the center of the bracket 400, which communicates with the inside of the pusher 310 and extends downward. 【0015】 The piston support member 500 has a hollow air passage 520 formed inside, and its upper end is inserted into and connected to the connector 410 of the bracket 400 in an interference fit manner, communicating with the pusher 310. The lower end of the piston support member 500 extends downward, and an air hole 510 is drilled in its side surface. The piston 600 is positioned at the lower end of the piston support member 500, and is positioned higher than the air hole 510, surrounding the outer casing of the piston support member 500. 【0016】 The dropper tube 700 is composed of a cylinder part 710 and a pipe-shaped suction member 720. The cylinder part 710 of the dropper tube 700 houses and is coupled with a piston 600 so that it can move up and down together with a piston support member 500 inside, and is arranged inside the wiper 200. When the cap 300 is rotated in the forward direction to close against the neck 110 of the container body 100, the piston 600 together with the piston support member 500 descends. When the cap 300 is rotated in the reverse direction to open against the neck 110 of the container body 100, the piston 600 together with the piston support member 500 can rise by a certain section S to generate a suction force. And the suction member 720 of the dropper tube 700 extends in a pipe shape from the lower center of the cylinder part 710, penetrates through the through hole 210 of the wiper 200 in a close contact state and is accommodated in the container body 100. When a suction force is generated in the cylinder part 710, a part of the content in the container body 100 is sucked and stored, and pneumatic pressure is generated by pressing the pusher 310 so that the stored content A can be discharged. A flow hole 730 is drilled at the lower end. 【0017】 The bushing member 800 is manufactured in a cylindrical shape and is coupled to the uppermost end of the cylinder part 710 of the dropper tube 700 by an interference fit method. In the process of opening the cap 300 by rotating it in the reverse direction against the neck 110 of the container body 100, while allowing the upward movement of the piston support member 500 and the piston 600 by a certain section S, it prevents the piston support member 500 and the piston 600 from being separated from the cylinder part 710 of the dropper tube 700. 【0018】 The concave-convex engagement member 900 is provided between the wiper 200 and the cylinder portion 710 of the dropper tube 700, and is for maintaining the cylinder portion 710 of the dropper tube 700 in a state of being accommodated inside the wiper 200 until the piston support member 500 and the piston 600 rise and contact the cushioning member 800 in the process of turning the cap 300 in the reverse direction with respect to the neck 110 of the container body 100 to open it. In an embodiment of the present invention, the concave-convex engagement member 900 includes an engagement groove 910 formed in a concave shape in the circumferential direction on the inner wall of the wiper 200, and an engagement protrusion 920 formed so as to protrude in a strip shape along the outer wall of the cylinder portion 710 of the dropper tube 700, and when the cap 300 is completely turned and closed with respect to the neck 110 of the container body 100, the engagement protrusion 920 can be engaged with the engagement groove 910 in a concave-convex manner to temporarily position-fix the dropper tube 700 inside the wiper 200. 【0019】 Next, the usage state of the automatic filling type dropper cosmetic container according to the present invention configured as described above will be described based on FIGS. 5 to 10. 【0020】 First, as shown in FIGS. 5 and 6, when the cap 300 in which the dropper tube 700 is disposed with respect to the neck 110 of the container body 100 is turned in the forward direction (the direction of arrow R1) and completely closed, the suction member 720 of the dropper tube 700 with an empty interior penetrates through the through-hole 210 of the wiper 200 and is immersed in the content A of the container body 100. Thus, when the cap 300 is completely turned and closed with respect to the neck 110 of the container body 100, the bracket 400 and the piston support member 500 also descend together with the cap 300, and the piston 600 is positioned at the lowermost part of the cylinder portion 710 of the dropper tube 700 (refer to the direction of the arrow in FIG. 6). Further, the cylinder portion 710 of the dropper tube 700 is also maintained in a state of being completely accommodated inside the wiper 200, and the concave-convex engagement member 900, that is, the engagement protrusion 920 is engaged with the engagement groove 910 in a concave-convex coupling manner, whereby the cylinder portion 710 of the dropper tube 700 is constrained inside the wiper 200. 【0021】 Then, as shown in Figures 7 and 8, when the cap 300 is turned in the opposite direction (in the direction of arrow R2) and gradually opened, the bracket 400 and the piston support member 500 rise from the container body 100 together with the cap 300, and the piston 600 rises for a certain distance until it comes into contact with the bushing member 800 while in close contact with the wall surface of the cylinder portion 710 (see the direction of the arrow in Figures 7 and 8). This upward movement of the piston 600 generates suction pressure inside the cylinder portion 710, and as a result, a portion of the contents (cosmetic liquid) A inside the container body 100 is drawn into the suction member 720 of the dropper tube 700 through the flow hole 730 and filled. 【0022】 Next, as shown in Figures 9 and 10, when the cap 300 is further rotated in the opposite direction (in the direction of arrow R2) to fully open it, the bracket 400 and piston support member 500 separate from the container body 100 along with the cap 300 as they rise, and the piston 600 pulls the cylinder portion 710 of the dropper tube 700 upward (see the direction of the arrow in Figure 9). As a result, the engagement projection 920 separates from the engagement groove 910, releasing the restraining force on the cylinder portion 710 of the dropper tube 700 from the inside of the wiper 200, and the suction member 720 of the dropper tube 700 comes out of the container body 100. At this point, the outer wall of the suction member 720 of the dropper tube 700 comes out in close contact with the through hole 210 of the wiper 200, and is thoroughly washed away. 【0023】 In this way, when the cap 300 is turned in the opposite direction relative to the container body 100 to remove the dropper tube 700, suction pressure is generated in the cylinder part 710, and the contents (cosmetic liquid) A are automatically filled (sucked) into the suction member 720 of the dropper tube 700, so that the contents can be used conveniently. That is, by pinching and pressing the pusher 310, the contents A that have filled the suction member 720 of the dropper tube 700 are ejected by air pressure, so that the contents can be used. 【0024】 Then, after completely discharging the contents A that have filled the suction member 720 of the dropper tube 700, when the cap 300 is turned to close the container body 100, as shown in Figures 5 and 6, the bracket 400 and the piston support member 500 descend, and the piston 600 also descends while in close contact with the cylinder portion 710 of the dropper tube 700 and is located at the lowest position. Furthermore, the cylinder portion 710 of the dropper tube 700 is also completely housed inside the wiper 200, and the interlocking projection 920 interlocks with the interlocking groove 910 in a concave-concave coupling manner, thereby restraining the cylinder portion 710 of the dropper tube 700 once again. [Industrial applicability] 【0025】 This invention can be widely applied to the field of "dropper-type cosmetic containers," which allow for more convenient use of the contents (cosmetic liquid) because the contents are automatically filled into the dropper tube when the cap is twisted open on the container body containing the contents.
