Description

Technical Field

[0001] The present invention relates to a stamp-type fluid injection container equipped with microneedles that can inject a fluid for skin or scalp care and treatment during the process of tapping the skin or scalp. In particular, it relates to a stamp-type fluid injection container equipped with microneedles that adopts a simple structure without a separate nozzle opening and closing structure and can uniformly and smoothly supply the fluid using the microneedles. Background Art

[0002] Generally speaking, it is necessary to directly supply a fluid for skin or scalp care, treatment, etc. to the skin or scalp, but there is a problem that the substantial effect cannot be fully exerted because the fluid is coated on the epidermal layer of the skin or scalp.

[0003] To solve the above problems, various forms of fluid injection containers that penetrate into the dermis (endothelium) of the skin or scalp rather than the epidermal layer using microneedles have been previously disclosed.

[0004] For example, in Korean Registered Patent No. 10-1993706, a connection cover is coupled to the upper part of a housing member (container) for accommodating a fluid, and a needle cover into which microneedles are inserted into slit grooves formed in parallel is coupled to the connection cover. An opening and closing rod and a nozzle rod are inserted into a nozzle hole in the center of the connection cover in a manner that can be elastically moved up and down by a spring. Thus, when the skin or scalp is pressed using the nozzle rod, the nozzle hole is opened, and the medicinal solution or fluid is thereby permeated and supplied to the dermis (endothelium) of the skin or scalp through the microneedles combined with the slit grooves of the connection cover and the needle cover.

[0005] However, the fluid injection container as described above adopts a complex structure of forming a separate nozzle opening and closing structure and a connection cover, and the fluid supplied through the nozzle hole of the connection cover cannot be directly supplied to the slit grooves of the needle cover, but is supplied to the entire needle cover through the front space of the connection cover. Therefore, there is a problem that the fluid cannot be uniformly and smoothly supplied to the slit grooves of the needle cover.

[0006] In addition, in Korean Registered Patent No. 10-1776154, a support part is coupled to the upper part of a housing member (container) without adopting a nozzle structure, a cover part into which microneedles are inserted into slit grooves formed in parallel is coupled to the support part, and a sponge member is further coupled to the upper part of the cover part. Thus, the fluid is permeated and supplied to the dermis (endothelium) of the skin or scalp through the microneedles in a structure without a nozzle opening and closing structure.

[0007] However, although there is no nozzle opening / closing structure in the fluid injection container as described above, there is a problem that the structure tends to be complicated due to the combination of a separate support part component, and the fluid in the housing component is directly supplied to the slit groove of the lid part and a separate fluid passage hole. Therefore, although smooth supply of the fluid can be ensured, an appropriate amount of fluid cannot be supplied, but rather an excessive supply and discharge problem will occur.

[0008] Moreover, during the storage or handling of the fluid injection container, there may also be a problem that the fluid leaks to the outside due to the opening of the fluid passage hole of the lid part.

[0038] Next, the preferred embodiments applicable to the present invention will be described in detail with reference to the accompanying drawings.

[0039] The stamp-type fluid injection container of the present invention equipped with microneedles, as Figures 1 to 7 shown, is composed of a container body 10, a needle outer cover 20, a sealing cover 30, and an end cap 40.

[0040] The container body 10 houses the fluid in the internal space, forms a threaded engaging portion 11 on the outer side of the upper part, and forms an engaging groove portion 12 on the inner side of the upper part.

[0041] At this time, the engaging groove portion 12 is formed with a stepped structure up and down, and preferably has a quadrilateral shape when viewed in a plane.

[0042] The needle outer cover 20 forms a main body 21 with a quadrilateral shape corresponding to the engaging groove portion 12 of the container body 10, and is fixedly coupled by being forcibly inserted into the engaging groove portion 12, and a stepped structure corresponding to the upper and lower steps of the engaging groove portion 12 is formed on the outside up and down.

[0043] In addition, slotted grooves 22 that penetrate up and down are formed side by side left and right in the needle outer cover 20, and microneedles 25 in a plate-like shape are respectively inserted into the slotted grooves 22.

[0044] At this time, the fine needles 25a protruding from the upper part of the microneedles 25 will protrude above the needle outer cover 20, and the slotted grooves 22 of the needle outer cover 20 are formed in an inclined cone structure whose width gradually expands downward. By using the blocking ridges 25b formed on the lower parts of both sides of the microneedles 25 for blocking, not only can the microneedles 25 be prevented from disengaging upward from the slotted grooves 22, but also the fluid can be smoothly supplied into the slotted grooves 22.

[0045] The sealing cover 30 is made of a rubber material and is installed in such a way as to cover the entire upper part of the engaging portion 11 of the container body 10, thereby preventing the fluid flowing out through the slotted grooves 22 of the needle outer cover 20 from leaking to the outside. In addition, a needle receiving groove 32 into which the fine needle 25a at the upper end of the microneedle 25 can be inserted is formed at the center of the lower part of the sealing cover 30.

[0046] The end cap 40 is threadedly coupled to the engaging portion 11 of the container body 10, and can seal the sealing cover 30 while pressing the sealing cover 30.

[0047] In particular, in the present invention, a fluid discharge hole 13 in the form of a long hole is formed on the bottom surface of the engaging groove portion 12 of the container body 10 along a direction intersecting with the slit grooves 22 of the needle cover 20, and an air hole 14 for achieving air circulation while preventing the fluid in the container body 10 from flowing out is formed above the engaging portion 11, so that the fluid can be smoothly supplied to the microneedles 25 by means of a simple structure without a separate opening and closing nozzle structure.

[0048] At this time, the fluid discharge hole 13 is not formed in a manner that penetrates the entire bottom surface of the engaging groove portion 12 of the container body 10, but is formed in the form of a long hole. Therefore, excessive supply of fluid can be avoided, and by forming it along a direction intersecting with the slit grooves 22 of the needle cover 20, the fluid can be evenly supplied to each of the slit grooves 22 of the needle cover 20.

[0049] In addition, a lower cover 15 made of rubber that can be opened and closed and is used for backfilling the fluid is forcibly coupled to the lower part of the container body 10.

[0050] As an unillustrated reference numeral, 10a is the internal space portion of the container body 10, and 15a is a step groove formed for coupling the lower cover 15 to the lower part of the container body 10.

[0051] Next, the operation and function of the present invention configured as described above will be described in detail.

[0052] First, the assembly process of the fluid injection container of the present invention will be described. In a state where the plate-shaped microneedles 25 are respectively inserted into the lower parts of the slit grooves 22 formed side by side on the left and right in the needle cover 20, they are inserted and assembled into the engaging groove portion 12 formed on the inner side of the upper part of the container body 10.

[0053] At this time, a fluid discharge hole 13 in the form of a long hole is formed on the bottom surface of the engaging groove portion 12 of the container body 10, and thus the assembly is carried out in a direction where the slit grooves 22 of the needle cover 20 and the fluid discharge hole 13 intersect each other.

[0054] In the state as described above, the sealing cover 30 is installed on the upper part of the container body 10. Since a needle receiving groove 32 is formed in the center of the lower part of the sealing cover 30, interference with the fine needles 25a at the upper ends of the microneedles 25 can be avoided.

[0055] Next, the end cap 40 is coupled to the engaging portion 11 on the outer side of the upper part of the container body 10.

[0056] In the state as described above, the fluid inside the container body 10 can be filled by separating the lower cover 15 coupled to the lower part of the container body 10, backfilling the fluid into the container body 10, and then re-coupling it.

[0057] The present invention assembled in the manner described above can prevent internal fluid from leaking to the outside by combining the sealing cover 30 on the upper part of the container body 10.

[0058] When it is necessary to use the fluid injection container of the present invention described above, it can be used after separating the end cap 40 from the upper part of the container body 10 and separating the sealing cover 30 on the upper part of the container body 10.

[0059] In the state prepared as described above, by using the fine needle 25a of the microneedle 25 assembled on the upper part of the container body 10 to tap the scalp, skin, etc., the fluid inside the container body 10 will be supplied to the microneedle 25 and injected into the micropores formed by the fine needle 25a.

[0060] Next, the above process will be described in more detail. When the fluid inside the container body 10 is supplied through the fluid discharge hole 13 formed in the shape of a long hole on the bottom surface of the engaging groove portion 12, it will be simultaneously supplied to the slit grooves 22 of the needle outer cover 20 formed side by side in a direction intersecting the fluid discharge hole 13.

[0061] In particular, the fluid discharge hole 13 is not formed in a way that penetrates the entire bottom surface of the engaging groove portion 12 of the container body 10, but in the shape of a long hole. Therefore, excessive supply of fluid can be avoided, and by forming it in a direction intersecting the slit grooves 22 of the needle outer cover 20, the fluid can be evenly supplied to each slit groove 22 of the needle outer cover 20.

[0062] Moreover, since the air hole 14 is formed in the upper part of the container body 10, external air can flow into the container body 10 while preventing the fluid from flowing out, thereby ensuring that the fluid inside the container body 10 can smoothly flow out through the fluid discharge hole 13.

[0063] As described above, an appropriate amount of fluid can be evenly supplied to the slit grooves 22 of the needle outer cover 20 through the fluid discharge hole 13 of the container body 10 and injected through the microneedle 25 combined with the slit grooves 22.

[0064] Thereby, the present invention combines the needle outer cover 20 with the microneedle 25 to the engaging groove portion 12 on the upper part of the container body 10, forms a fluid discharge hole 13 in the shape of a long hole on the bottom surface of the engaging groove portion 12 in a direction intersecting the slit grooves 22 of the needle outer cover 20, and forms an air hole 14 in the upper part of the container body 10 that can achieve air circulation while preventing fluid from flowing out. Thereby, not only can fluid be supplied to the microneedle 25 in an appropriate amount, evenly, and smoothly without a separate nozzle opening and closing structure, but also fluid leakage can be prevented usually, thereby improving manufacturing productivity, use reliability, and economy.
