Description

Paste discharge control mechanism

[0001] The present invention relates to a paste discharge control device, and more specifically, to a paste discharge control device capable of evenly applying paste by controlling the discharge amount.

[0002] This patent application claims priority to Republic of Korea Patent Application No. 10-2024-0054567, filed with the Korean Intellectual Property Office on April 24, 2024, the disclosure of which is incorporated herein by reference.

[0003] Typically, liquid compositions applied to the skin or hair, or paste-type compositions including gels, creams, and waxes, are distributed in containers such as bottles or tubes. Containers such as bottles dispense the composition through a pump or automatic discharge device. Flexible containers such as tubes dispense the composition through a discharge port when the container body is pressurized. Users can dispense the dispensed composition onto their hands and apply it directly to the skin, or use various tools such as puffs and sticks to apply it to the skin. Additionally, various application devices that can be attached to containers have been used to improve user convenience.

[0004] However, conventional application devices had problems in that the composition could not be discharged consistently depending on changes in internal pressure applied to the container, and it was difficult to apply it evenly to the skin.

[0033]

[0034] Hereinafter, preferred embodiments of the present invention designed to solve the above problems will be described in detail with reference to the attached drawings.

[0035] Figure 1 is a perspective view showing the configuration of a paste discharge control mechanism according to one embodiment of the present invention.

[0036] Referring to FIG. 1, a paste discharge control mechanism according to one embodiment of the present invention may include a mechanism body (1100), a slide plate (1200), a filter unit (1300), and a container (1400).

[0037] The container (1400) can accommodate a paste type composition.

[0038] The paste-type composition may be a viscous fluid. In one embodiment, the paste-type composition may include any one of an aqueous solution, an emulsion, or an oil. In another embodiment, the paste-type composition may include any one of a gel, a cream, a wax, or a mousse.

[0039] In one embodiment, the container (1400) may be a flexible container, such as a tube. The flexible container is easily deformed by external pressure and can discharge the composition contained therein by the pressure. The flexible container may be a tube made of rubber, plastic, or metal.

[0040] In another embodiment, the container (1400) may be a rigid container, such as a bottle. Since the rigid container is rigid and has a fixed shape, the composition contained therein can be discharged using a pump or an automatic discharge device. The rigid container may be a bottle made of plastic or metal.

[0041] The container (1400) may have a discharge port for discharging the composition it contains. The discharge port may have a thread that can be coupled to the device body (1100).

[0042] The outlet of the container (1400) may vary in size from container to container.

[0043] The filter unit (1300) can be screw-connected to the outlet of the container (1400) on one side. The outlet of the container (1400) can be inserted into and connected to the filter unit.

[0044] The filter unit (1300) can be screw-connected to the other side of the device body (1100). The filter unit (1300) can be inserted into and connected to the device body (1100).

[0045] The container (1400) and the device body (1100) can be combined except for the filter unit (1300). The user can appropriately select whether to combine the container (1400) and the device body (1100) including the filter unit (1300).

[0046] The device body (1100) can be combined with a filter unit (1300) or a container (1400). The composition discharged from the container (1400) can be discharged through a discharge port (1130) formed in the device body.

[0047] The slide plate (1200) is coupled to the device body (1100) and can slide up and down. The slide plate (1200) can control the discharge of the composition by opening or closing the discharge port (1130) depending on the slid position.

[0048] Fig. 2 is a perspective view showing a filter unit according to one embodiment of the present invention.

[0049] Figure 3 is a bottom plan view showing a state in which the device body and the filter unit are combined according to one embodiment of the present invention.

[0050] Referring to FIGS. 2 and 3, a filter unit (1300) according to one embodiment of the present invention may include a mesh filter (1310) inside a cylindrical space connected to a flow path (1120).

[0051] Even when a strong pressure is suddenly applied inside the container (1400), the mesh filter (1310) can discharge the composition consistently. The amount of pressure that the mesh filter (1310) can withstand may vary depending on the mesh size. The smaller the mesh size, the more consistently the composition can be discharged even under strong pressure.

[0052] The mesh filter (1310) can uniformly disperse particles of the composition contained in the container (1400). The composition contained in the container may solidify and form lumps within the container. The lumps of the solidified composition impede the movement of the composition and prevent the composition from being discharged uniformly. The lumps of the solidified composition may be pulverized into small particles as they pass through the mesh filter (1310).

[0053] The filter unit (1300) may include a filter upper portion (1320) coupled with a coupling portion (1110) of the device body (1100) and a filter lower portion (1330) coupled with a discharge port of a container (1400).

[0054] The filter upper portion (1320) has a cylindrical shape and may have an outer diameter identical to the inner diameter of the coupling portion (1110) so that it can be coupled with the coupling portion (1110) of the device body (1100). The filter upper portion (1320) may have a screw thread formed thereon that can be coupled with the screw thread (1111) of the coupling portion (1110).

[0055] The filter lower part (1330) can be formed in a cylindrical shape, and the discharge portion of the container (1400) can be inserted into and combined with the filter lower part (1330). A screw thread that can be combined with the discharge port of the container (1400) can be formed on the inner circumference of the filter lower part (1330).

[0056] The filter lower portion (1330) may have various sizes depending on the size of the outlet of the container (1400). Accordingly, the filter portion (1300) may be a plurality of filter portions (1300) having different sizes of the filter lower portions (1330). The user may select and use a filter portion (1300) that matches the size of the outlet of the container (1400) among the plurality of filter portions (1300).

[0057] The mesh material of the mesh filter (1310) may be fiber or metal.

[0058] Figure 4 is a cross-sectional view showing a cross-section of a device body according to one embodiment of the present invention.

[0059] Figure 5 is a perspective view showing a device body according to one embodiment of the present invention.

[0060] Referring to FIGS. 4 and 5, the device body (1100) according to one embodiment of the present invention may include a coupling portion (1110), a flow path (1120), and an outlet (1130).

[0061] The coupling part (1110) may be formed in a cylindrical shape at the lower part of the device body (1100). The coupling part (1110) may be screw-connected to the outlet of the container (1400) or screw-connected to the filter part (1300).

[0062] A screw thread (1111) may be formed on the inner cylindrical surface of the joint (1110).

[0063] A path (1120) through which the composition can move can be formed inside the device body (1100). One end of the path (1120) is connected to a connecting portion (1110) and the opposite end is connected to a discharge port (1130).

[0064] The euro (1120) may be formed to be inclined in the direction of the outlet of the container (1400) so that the composition can move smoothly.

[0065] The discharge port (1130) may be formed in a transversely long slit shape. The composition moving along the flow path (1120) is discharged through the slit-shaped discharge port (1130), thereby being applied to the skin in a transversely wide and thin manner.

[0066] The discharge port (1130) may be formed in the form of one or more slits spaced apart at regular intervals vertically. The composition passing through the flow path (1120) may be discharged through the long and thin slit-shaped discharge port, thereby being applied evenly and widely to the skin.

[0067] In one embodiment, one or more discharge ports (1130) may be formed. For example, there may be one discharge port or five discharge ports. When multiple discharge ports (1130) are formed, the amount of the composition discharged may also increase as the number of open discharge ports (1130) increases.

[0068] One embodiment of the present invention adopts a method of increasing the number of slit-shaped discharge ports (1130) rather than a method of widening the width of the discharge port as a means of increasing the amount of discharged composition. The method of increasing the number of slit-shaped discharge ports (1130) may be advantageous in maintaining a constant discharge amount of the composition compared to the method of widening the width of the discharge port.

[0069] Generally, pressure is applied inside the container to discharge the composition contained in the container, but it is difficult to maintain a constant discharge amount of the composition depending on the viscosity of the composition or the strength of the pressure. In particular, as the size of the discharge port increases, the discharge amount of the composition increases, making it even more difficult to maintain a constant discharge amount.

[0070] However, in one embodiment of the present invention, the discharge amount is controlled by increasing the number of discharge ports (1130) that are opened while maintaining the width of the discharge port (1130) constant, so it is easy to maintain the discharge amount constant.

[0071] In one embodiment of the present invention, the slit width of the discharge ports (1130) may increase in order from the upper discharge port to the lower discharge port. For example, if there are five discharge ports (1130), the slit width of the uppermost discharge port may be formed to be 1 mm, and the slit width may increase by 0.5 mm toward the lower discharge port. According to one embodiment of the present invention, as the number of open discharge ports (1130) increases, the discharge amount of the composition increases exponentially.

[0072] 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 one such embodiment, as the number of open discharge ports (1130) increases, the discharge amount of the composition increases consistently.

[0073] According to one embodiment of the present invention, the device body (1100) may have a groove (1140) formed longitudinally on the left and right sides of the discharge port (1130) to guide the up and down movement of the slide plate (1200) by bringing the slide plate (1200) into close contact with the discharge port (1130).

[0074] 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 therein.

[0075] Part of the left and right sides of the slide plate (1200) can be inserted into the recessed groove (1140) and moved up and down. The slide plate (1200) can only move longitudinally along the recessed groove (1140).

[0076] The width of the inlet 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).

[0077] The device body (1100) may have a plurality of rear fixing grooves (1150) formed in a row on the left and right of the discharge port (1130), to which rear fixing projections (1220) for fixing the slide plate (1200) that moves up and down are coupled.

[0078] The rear fixed groove (1150) can be formed to fit the position where the slide plate (1200) opens and closes each discharge port (1130).

[0079] In one embodiment, the rear fixing groove (1150) can engage all of the rear fixing projections of the slide plate (1200) when the slide plate (1200) has all of the outlets (1130) closed. The rear fixing groove (1150) can engage some of the rear fixing projections of the slide plate (1200) when the slide plate (1200) is in a position where some of the outlets (1130) are open.

[0080] The device body (1100) may have a plurality of front fixing grooves (1160) formed in a row on the inner surface of the recessed groove (1140) to which front fixing projections (1210) for fixing the slide plate (1200) that moves up and down are coupled.

[0081] The front fixing groove (1160) may be formed to match the position where the slide plate (1200) opens and closes each discharge port (1130). The front fixing groove (1160) may be formed on a surface facing the rear fixing groove (1150). The front fixing groove (1160) may be formed to have a height that is staggered from the rear fixing groove (1150).

[0082] The front fixing groove (1160) and the rear fixing groove (1150) may be hemispherical or have another concave shape to match the shape of the front fixing protrusion (1210) and the rear fixing protrusion (1220).

[0083] Figure 6 is a perspective view showing a state in which a mechanism body and a slide plate are combined according to one embodiment of the present invention.

[0084] Referring to FIG. 6, a slide plate (1200) according to one embodiment of the present invention can be inserted into the mechanism body (1100) and moved up and down.

[0085] The slide plate (1200) can sequentially open or close each slit-shaped discharge port (1130) by moving up and down along the inlet groove (1140).

[0086] The front fixing protrusion (1210) and the rear fixing protrusion (1220) formed on the front and rear sides of the slide plate (1200) are joined to the front fixing groove (1160) and the rear fixing groove (1150) formed on the mechanism body (1100), so that the slide plate (1200) can be fixed in the moved position.

[0087] Figure 7 is a side view showing a slide plate according to one embodiment of the present invention.

[0088] Figure 8 is a front view and a rear view showing a slide plate according to one embodiment of the present invention.

[0089] Referring to FIGS. 7 and 8, a 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) may have a transverse length formed to match the spacing between the left and right recessed grooves (1140) so that it can be inserted into the recessed grooves (1140).

[0090] The slide plate (1200) may have a handle (1230) that allows a user to grip the slide plate (1200). In one embodiment, the side of the slide plate (1200) having the handle (1230) may be L-shaped.

[0091] The slide plate (1200) may have a plurality of front fixing protrusions (1210) formed in a row on the left and right sides of the slide plate (1200) that can fix the position after moving up and down. As described above, the front fixing protrusions (1210) can be combined with the front fixing grooves (1160) of the mechanism body (1100) to fix the position of the slide plate (1200).

[0092] The slide plate (1200) may have a plurality of rear fixing protrusions (1220) formed in a row on the left and right sides of the slide plate (1200) that can fix the position after moving up and down. The rear fixing protrusions (1220) can be combined with the rear fixing grooves (1150) of the mechanism body (1100) to fix the position of the slide plate (1200).

[0093] A slide plate (1200) according to one embodiment of the present invention may be provided with a lubricating pad (1240) on the front surface to reduce friction with the skin. The lubricating pad (1240) may be a rectangular pad having a predetermined thickness.

[0094] The lubricating pad (1240) may be made of a material such as silicone, polymer, or Teflon. The lubricating pad (1240) may contain ingredients that can soothe and moisturize the skin, such as vitamins, oils, or shea butter.
