Description

Technical Field

[0001] The present invention relates to a paste discharge adjusting device, and more particularly, to a paste discharge adjusting device capable of adjusting the discharge amount to uniformly apply the paste.

[0002] The present invention claims priority from Korean Patent Application No. 10-2024-0054567, filed with the Korean Intellectual Property Office on April 24, 2024, and the matters disclosed in the above patent application are incorporated herein by reference.

Background Art

[0003] Generally, liquid-type compositions applied to the skin or hair, or paste-type compositions including gels, creams, waxes, etc. are distributed in containers such as bottles and tubes. Compositions in containers such as bottles are discharged through pumps or automatic discharge devices. In the case of flexible containers such as tubes, when the main body of the container is pressurized, the composition is discharged through the discharge part. Users either directly apply the discharged composition to the skin by hand or use various tools such as puffs and sticks to apply it to the skin. In addition, various application mechanisms that can be coupled to the container have been used for the purpose of improving user convenience.

[0004] However, conventional application mechanisms have a problem in that the composition cannot be discharged constantly according to changes in the internal pressure applied to the container, and it is difficult to uniformly apply it to the skin.

[0005] As a related prior art, there is Korean Patent Publication No. 10-2013-0105830 (Title of Invention: Applicator for Dispensing Adhesive or Sealant Substances, Publication Date: September 26, 2013).

Modes for Carrying Out the Invention

[0024] In this specification, when assigning reference numbers to components in each drawing, it should be noted that, to the extent possible, the same component will have the same number, even if it appears in other drawings. In this specification, singular types include plural types unless otherwise specified. The terms "comprises" and / or "comprising" used in this specification do not preclude the existence or addition of one or more other components in addition to the components mentioned.

[0025] The above-described objectives, other objectives, features, and advantages of the present invention will be readily apparent through the following preferred embodiments relating to the attached drawings. However, the present invention is not limited to the embodiments described herein and can be embodied in other forms. Rather, the embodiments presented herein are provided to ensure that the disclosed content is thorough and complete, and that the idea of ​​the present invention is fully conveyed to the ordinary person in the art.

[0026] The following describes in detail a preferred embodiment of the present invention, which was devised to solve the aforementioned problems, with reference to the attached drawings.

[0027] Figure 1 is a coupled perspective view showing the configuration of a paste dispensing adjustment mechanism according to one embodiment of the present invention.

[0028] Referring to Figure 1, the paste dispensing adjustment mechanism according to one embodiment of the present invention may include a mechanism body 1100, a slide plate 1200, a filter section 1300, and a container 1400.

[0029] Container 1400 can contain a paste-type composition.

[0030] A paste-type composition can be a viscous fluid. In one embodiment, the paste-type composition may include any one of an aqueous solution, an oily liquid, or an oil. In another embodiment, the paste-type composition may include any one of a gel, a cream, a wax, or a mousse.

[0031] According to one embodiment, the container 1400 can be a flexible container such as a tube. The flexible container is easily deformed by external pressure and can discharge the composition contained inside by pressure. The flexible container may be a tube made of rubber, plastic, or metal material.

[0032] In other embodiments, the container 1400 can be a rigid container such as a bottle. Because the rigid container is hard and its shape is fixed, the composition contained inside can be discharged using a pump or an automatic discharge device. The rigid container may be a bottle made of plastic or metal.

[0033] The container 1400 may be equipped with a discharge port for discharging the composition it contains. The discharge port may be equipped with a screw thread that can be connected to the body 1100 of the mechanism.

[0034] The outlets of container 1400 can be of different sizes from one container to another.

[0035] The filter section 1300 can be connected to the outlet of the container 1400 by a screw on one side. The outlet of the container 1400 can be inserted into and connected to the filter section.

[0036] The other end of the filter section 1300 can be connected to the body 1100 of the mechanism by a screw. The filter section 1300 can be inserted into and connected to the body 1100 of the mechanism.

[0037] The container 1400 and the mechanism body 1100 can be joined together, excluding the filter section 1300. The user can appropriately choose whether or not to join the container 1400 and the mechanism body 1100, including the filter section 1300.

[0038] The body 1100 of the mechanism can be connected to a filter section 1300 or a container 1400. The composition discharged from the container 1400 can be discharged to a discharge port 1130 formed in the body of the mechanism.

[0039] The slide plate 1200 is coupled to the body 1100 of the mechanism and can slide vertically. The slide plate 1200 can adjust the discharge of the composition by opening or closing the discharge port 1130 depending on the slid position.

[0040] Figure 2 is a perspective view showing a filter section according to one embodiment of the present invention.

[0041] Figure 3 is a lower plan view showing the body and filter section of the mechanism according to one embodiment of the present invention in a connected state.

[0042] Referring to Figures 2 and 3, the filter section 1300 according to one embodiment of the present invention may include a mesh-type filter 1310 inside a cylindrical space connected to the flow path 1120.

[0043] Even when a sudden, strong pressure is applied inside the container 1400, the mesh filter 1310 can discharge the composition at a constant rate. Depending on the mesh size, the pressure range that the mesh filter 1310 can withstand can be changed. The smaller the mesh size, the more consistently the composition can be discharged even under strong pressure.

[0044] The mesh filter 1310 can homogenize the particles of the composition contained in the container 1400. The composition contained in the container may solidify inside the container and form clumps. These solidified clumps of composition hinder the movement of the composition and prevent it from being discharged uniformly. These solidified clumps of composition can be pulverized into smaller particles through the mesh filter 1310.

[0045] The filter section 1300 may include an upper filter section 1320 that connects to a coupling section 1110 of the mechanism body 1100, and a lower filter section 1330 that connects to the outlet of the container 1400.

[0046] The upper filter portion 1320 is cylindrical and can have an outer diameter similar to the inner diameter of the coupling portion 1110 of the body 1100 of the mechanism. The upper filter portion 1320 can have threads formed on it that allow it to connect with the threads 1111 of the coupling portion 1110.

[0047] The lower filter portion 1330 can be formed in a cylindrical shape, and the discharge portion of the container 1400 can be inserted into and connected to the lower filter portion 1330. Threads can be formed on the inner circumferential surface of the lower filter portion 1330 to connect to the discharge port of the container 1400.

[0048] The lower filter section 1330 can have various sizes depending on the size of the outlet of the container 1400. Therefore, the filter section 1300 may consist of multiple filter sections 1300, each with a different size for the lower filter section 1330. The user can select and use the filter section 1300 that best fits the size of the outlet of the container 1400 from among the multiple filter sections 1300.

[0049] The mesh material of the mesh-type filter 1310 can be fiber or metal.

[0050] Figure 4 is a cross-sectional view showing a cross-section of the body of a mechanism according to one embodiment of the present invention.

[0051] Figure 5 is a perspective view showing the body of a mechanism according to one embodiment of the present invention.

[0052] Referring to Figures 4 and 5, the body 1100 of the mechanism according to one embodiment of the present invention may include a coupling portion 1110, a flow path 1120, and a discharge port 1130.

[0053] The coupling portion 1110 can be formed in a cylindrical shape at the lower part of the body 1100 of the mechanism. The coupling portion 1110 can be connected to the outlet of the container 1400 by a screw or to the filter portion 1300 by a screw.

[0054] Screw threads 1111 can be formed on the inner circumferential surface of the cylinder of the joint portion 1110.

[0055] A flow channel 1120 can be formed inside the body 1100 of the mechanism, through which the composition can move. One end of the flow channel 1120 is connected to the coupling 1110, and the other end is connected to the discharge port 1130.

[0056] The flow path 1120 can be formed in a direction that is inclined from the outlet of the container 1400 so that the composition can move smoothly.

[0057] The discharge port 1130 can be formed in the shape of a slit that is elongated laterally. The composition that has moved along the flow path 1120 is discharged through the slit-shaped discharge port 1130, so that it is applied to the skin in a way that is wide laterally and thin in thickness.

[0058] The discharge port 1130 can be formed into one or more slit shapes spaced at regular intervals vertically. The composition, via the flow path 1120, can be applied to the skin in a uniform and wide manner by being discharged through the long, thin slit-shaped discharge ports.

[0059] In one embodiment, one or more discharge ports 1130 can be formed. For example, there can be one or five discharge ports. When multiple discharge ports 1130 are formed, the amount of composition discharged may increase as the number of open discharge ports 1130 increases.

[0060] One embodiment of the present invention employs a method of increasing the number of slit-shaped discharge ports 1130 as a means of increasing the amount of composition discharged, rather than widening the width of the discharge port. Increasing the number of slit-shaped discharge ports 1130 may be more advantageous than widening the width of the discharge port in maintaining a constant discharge rate of the composition.

[0061] Generally, pressure is applied inside a container to dispense a composition, because it is difficult to maintain a constant discharge rate depending on the viscosity of the composition and the pressure applied. In particular, as the size of the discharge port increases, the amount of composition dispensed increases, making it even more difficult to maintain a constant discharge rate.

[0062] However, in one embodiment of the present invention, the discharge volume is adjusted by increasing the number of open discharge ports 1130 while keeping the width of the discharge ports 1130 constant, so it is easy to maintain a constant discharge volume.

[0063] In one embodiment of the present invention, the discharge ports 1130 can be configured such that the slit width gradually widens from the upper discharge ports to the lower discharge ports. For example, if there are five discharge ports 1130, the slit width of the uppermost discharge port can be formed to be 1 mm, and the slit width can be formed to increase by 0.5 mm for each lower discharge port. According to this embodiment, the amount of composition discharged increases exponentially as the number of open discharge ports 1130 increases.

[0064] In another embodiment, the discharge ports 1130 may all have the same slit width. For example, five discharge ports 1130 may all have the same slit width of 1 mm. According to this embodiment, the amount of composition discharged increases at a constant rate as the number of open discharge ports 1130 increases.

[0065] In the mechanism according to one embodiment of the present invention, the body 1100 can be fitted in close contact with the discharge port 1130, and recessed grooves 1140 that guide the vertical movement of the slide plate 1200 can be formed to the left and right of the discharge port 1130, extending in the vertical direction.

[0066] The recessed groove 1140 may have a concave cross-section. The recessed groove 1140 may be formed to match the thickness and vertical length of the slide plate 1200 so that the slide plate 1200 can be inserted.

[0067] Parts of the left and right sides of the slide plate 1200 are inserted into the recessed groove 1140, allowing for vertical movement. The slide plate 1200 can only move vertically along the recessed groove 1140.

[0068] The width of the recessed groove 1140 can be formed to match the thickness of the slide plate 1200 so that the slide plate 1200 can be in close contact with the discharge port 1130.

[0069] The body 1100 of the mechanism can have multiple rear fixing grooves 1150 formed in a row on the left and right sides of the discharge port 1130, to which rear fixing projections 1220 that fix the vertically moved slide plate 1200 are connected.

[0070] The rear fixing groove 1150 can be formed to align with the position where the slide plate 1200 opens and closes each discharge port 1130.

[0071] According to one embodiment, the rear fixing groove 1150 can be coupled to the fixing projection on the rear surface of the slide plate 1200 when the slide plate 1200 closes all of the discharge ports 1130. The rear fixing groove 1150 can be partially coupled to the fixing projection on the rear surface of the slide plate 1200 when the slide plate 1200 is in a position that opens some of the discharge ports 1130.

[0072] The body 1100 of the mechanism can have multiple front fixing grooves 1160 formed in a row on the inner surface of the recessed groove 1140, to which front fixing protrusions 1210 that fix the vertically moved slide plate 1200 are connected.

[0073] The front fixing groove 1160 can be formed to match the position in which the slide plate 1200 opens and closes each discharge port 1130. The front fixing groove 1160 can be formed on the surface facing the rear fixing groove 1150. The front fixing groove 1160 can be formed to intersect with the rear fixing groove 1150 at a height.

[0074] The front fixing groove 1160 and the rear fixing groove 1150 may be hemispherical or other concave in shape to match the shape of the front fixing projection 1210 and the rear fixing projection 1220.

[0075] Figure 6 is a perspective view showing the body and slide plate of a mechanism according to one embodiment of the present invention in a connected state.

[0076] Referring to Figure 6, the slide plate 1200 according to one embodiment of the present invention is inserted into the body 1100 of the mechanism and can move up and down.

[0077] The slide plate 1200 can move up and down along the recessed groove 1140, sequentially opening or closing each of the slit-shaped discharge ports 1130.

[0078] The front fixing protrusions 1210 and rear fixing protrusions 1220 formed on the front and rear surfaces of the slide plate 1200 are connected to the front fixing grooves 1160 and rear fixing grooves 1150 formed on the body 1100 of the mechanism, thereby allowing the slide plate 1200 to be fixed in the moved position.

[0079] Figure 7 is a side view showing a slide plate according to one embodiment of the present invention.

[0080] Figure 8 shows a front view and a rear view of a slide plate according to one embodiment of the present invention.

[0081] Referring to Figures 7 and 8, the slide plate 1200 according to one embodiment of the present invention may be a T-shaped plate having a predetermined thickness. The slide plate 1200 can be formed to have a lateral length that matches the distance between the left and right recessed grooves 1140 so that it can be inserted into the recessed grooves 1140.

[0082] The slide plate 1200 may be equipped with a handle 1230 that allows the user to grip the slide plate 1200. According to one embodiment, the side of the slide plate 1200 equipped with the handle 1230 may be L-shaped.

[0083] The slide plate 1200 can have multiple front fixing protrusions 1210 formed in a row on the left and right sides of the slide plate 1200, which can fix its position after it has been moved up and down. As described above, the front fixing protrusions 1210 can be coupled with the fixing grooves 1160 on the front of the mechanism body 1100 to fix the position of the slide plate 1200.

[0084] The slide plate 1200 can have a plurality of rear fixing protrusions 1220 formed in a row on the left and right sides of the slide plate 1200, which can fix its position after it has been moved up and down. The rear fixing protrusions 1220 can be coupled with fixing grooves 1150 on the rear surface of the mechanism body 1100 to fix the position of the slide plate 1200.

[0085] A slide plate 1200 according to one embodiment of the present invention may be provided with a lubricating pad 1240 on its front surface that can reduce friction with the skin. The lubricating pad 1240 may be a rectangular pad having a predetermined thickness.

[0086] The lubricating pad 1240 may be made of materials such as silicone, polymer, or Teflon®. The lubricating pad 1240 may also contain ingredients that can soothe and moisturize the skin, such as vitamins, oils, or shea butter.

[0087] As described above, although embodiments are described by limited embodiments and drawings, various modifications and variations can be made from the above description by a person with ordinary skill in the art. For example, the described technology may be carried out in a procedure different from the described method, and / or the components of the described structure, apparatus, etc. may be combined or assembled in a manner different from the described method, or replaced or substituted with other components or equivalents, and the appropriate results may still be achieved.
