Description

Needle assembly for container mounting

The present disclosure relates to needle assemblies mounted to containers, such as vials.

In general, various functional solutions are used for skin care such as skin aging prevention or treatment. By forming micropores in the skin, the functional solution can penetrate the skin more effectively. Needles have been developed and used to form micropores on the skin. When a device equipped with a needle is rubbed against the skin, micropores are formed in the skin. However, these devices can only form micropores on the skin, so the user has to apply the solution to the skin separately after the micropores are formed.

Accordingly, the present applicant has developed a device capable of easily applying a solution such as a drug or lotion while forming micropores on the skin. Korea Patent Registration No. 1647009 discloses a device developed and patented by the present applicant, which is inserted into standardized vial-shaped containers and discharges a solution using beads. In addition, Korean Patent Registration No. 1658229 discloses a device developed and patented by the present applicant, and a structure in which a connector is mounted on the outer diameter of a vial and combined with a roller. In addition, Korean Patent Registration No. 1686226 discloses a structure that is mounted on the inner diameter of a container and discharges a solution through a roller on the principle of free fall by gravity.

However, although these devices are easy to use with low-viscosity materials, they are almost impossible to use in the case of a viscous solution, and there is a problem in that the discharge of the solution cannot be properly controlled even in the case of a drug or lotion with little viscosity. Accordingly, even with a slight impact, the solution continues to flow out during use, resulting in heavy waste and inconvenient to use.

In addition, in the case of the prior art, it is unsanitary because it is not possible to prevent the reverse flow of blood, silver, various contaminants, and bacteria from the skin into the container while using the needle.

In addition, since the needle is integrally formed, it is difficult to replace other types of needles having different shapes, sizes, and structures.

An object of the present invention is to provide a needle assembly for mounting a container that can be used by discharging the solution in the container more effectively regardless of the viscosity of the solution.

The container 100 is a small bottle structure made of glass or plastic having an accommodation space therein, and may be, for example, a vial. An inlet 110 for discharging a solution may be formed at the upper end of the container 100 .

The needle assembly of this embodiment may be selectively mounted on the inlet 110 of the open container 100 to receive the solution contained in the container 100 .

As shown in Figure 1, the needle assembly of this embodiment, the head portion 10 having at least one or more needles, supports the head portion 10, and an outlet ( 21) is formed in the holder portion 20, one end of the holder portion 20 is installed, the other end is detachably coupled to the inlet 110 of the container 100, the holder portion 20 and the container 100 inlet The body part 30 communicating between the 110 and accommodating the solution discharged from the inlet 110 of the container 100, is formed in the body part 30 and holds the solution accommodated by applying pressure inside the body part 30 It may include a pumping unit 40 for discharging to the unit 20 .

The body portion 30 of this embodiment is formed at one end of the fitting groove portion 32 to fit the fitting portion 24 formed at the front end of the holder portion 20, and is formed at the other end of the container 100 inlet ( It may include a mounting portion 34 that is fitted and coupled to the 110).

The fitting groove portion 32 and the mounting portion 34 may be integrally formed to form one body portion 30 .

The body part 30 has a hollow structure in which the fitting groove part 32 and the mounting part 34 which are both ends are open and the inside is empty. Accordingly, the solution supplied from the inlet 110 of the container 100 may be discharged to the outlet 21 of the holder 20 mounted on the body 30 through the inside of the hollow body 30 .

The fitting groove portion 32 is formed in a shape corresponding to the fitting portion 24 of the holder portion 20 so that the fitting portion 24 may be fitted and coupled thereto. Accordingly, when the body portion 30 is mounted on the container 100, only the holder portion 20 can be separated from the fitting groove portion 32 to be easily replaced.

In the present embodiment, the mounting portion 34 may be coupled to the inlet 110 of the container 100 in a cylindrical shape so as to be fitted to the outer diameter of the inlet 110 in an interference fit manner.

At least one rib 35 in close contact with the outer circumferential surface of the inlet 110 of the container 100 may be formed along the inner circumferential surface of the mounting portion 34 . Accordingly, airtightness between the inlet 110 of the container 100 and the mounting part 34 may be improved.

In another embodiment, as shown in FIG. 1 , the mounting portion 34 may be formed of a tube 36 fitted to the inner diameter of the inlet 110 of the container 100 . The tube 36 communicates with the inside of the body 30 in a cylindrical shape. The tube 36 may be coupled to the inner diameter of the inlet 110 of the container 100 by interference fitting. The tube 36 also has at least one rib 35 in close contact with the inner circumferential surface of the inlet 110 of the container 100 may be formed along the outer circumferential surface on the inner circumferential surface for close coupling with the inlet 110 of the container 100 .

Hereinafter, the present embodiment will be described as an example of a structure in which the mounting portion 34 is installed by covering the outer diameter of the inlet 110 of the container 100 .

The fitting groove portion 32 or the mounting portion 34 of the body portion 30 may be formed of an elastic material including silicone, rubber, or soft resin. Accordingly, even when the outer diameter or inner diameter of the inlet 110 of the container 100 is not standardized and is different, the body portion 30 can be tightly mounted to the container 100 to be coupled.

The pumping part 40 may be integrally formed on one side of the body part 30 . The pumping part 40 is formed in the body part 30 and selectively applies pressure to the inside of the body part 30 to discharge the solution to the head part 10 through the outlet 21 .

As shown in FIG. 3 , the pumping unit 40 of this embodiment is formed on at least one surface of the body unit 30 , is formed in a hemispherical shape, is convexly curved outwardly, and is elastically pressed by an external force to form the body unit 30 . ) may be a structure that applies pressure to the inside.

The pumping part 40 may be formed to have a relatively thin thickness compared to the body part 30 so that the user can easily press it.

Accordingly, by applying pressure to the inside by pressing the pumping unit 40 if necessary in a state where the body 30 is mounted on the inlet 110 of the container 100, the solution can be discharged to the head 10 conveniently. have. In addition, in this embodiment, the pumping unit 40 is pressurized to discharge only the required amount of the solution when necessary.

In a state in which the pumping unit 40 is not driven, there is no pressure fluctuation in the body 30, and the outlet 21 of the holder 20 is blocked by a check valve 50 to be described later, so the solution is not discharged to the outside. .

Therefore, regardless of the viscosity of the solution, any solution can be properly discharged through the outlet 21 of the holder 20 connected to the body 30 using the pressure applied through the pumping unit 40 .

The pumping unit 40 may be formed on opposite sides of the body 30 , respectively. Accordingly, the user can apply pressure to the body portion 30 by easily pressing the pumping portion 40 disposed on both sides.

The pumping part 40 of this embodiment is formed like the body part 30 , and has a simple structure formed convex to the outside, making it easy to manufacture, and can effectively apply pressure to the inside of the body part 30 .

Accordingly, the user can discharge the solution only when necessary by pressing the pumping unit 40 formed on the body 30 .

That is, the solution accommodated in the container 100 is supplied to the body portion 30 mounted on the inlet 110, and through the outlet 21 of the holder portion 20 mounted on the tip of the body portion 30, the head portion ( 10) is supplied. In this process, when the pumping part 40 formed in the body part 30 is pressed, the pumping part 40 is elastically deformed and pressed inward, and pressure is applied to the inside of the body part 30 . Accordingly, the solution in the body 30 may be discharged through the outlet 21 of the holder 20 .

When the external force is removed from the pumping part 40 , the pumping part 40 is convexly restored to its original state by the elastic restoring force of the pumping part 40 itself.

In this way, by providing the pumping unit 40 in the body portion 30, it is possible to use the solution by properly discharging only the required amount when necessary.

The head unit 10 may be in contact with the skin of the human body while being supported by the holder unit 20 .

The head unit 10 may be provided with a needle in the form of a fine needle with a sharp tip, thereby forming fine pores in the skin.

The head portion 10 of the present embodiment may have various structures including a roller-type head portion or a stamp-type head portion.

In the case of the roller type, the needle is formed along the outer circumferential surface, and as it rotates along the skin, micropores can be formed in the skin.

As shown in Fig. 1, the roller-type head unit 10 has at least one circular disk needle 12 continuously formed at intervals along the outer tip, and a circular spacer installed between the disk needle 12. (14) has a structure in which they are alternately arranged on one axis. The installation number of the disk needle 12 and the spacer 14 can be variously modified according to the size of the head part 10 .

The spacer 14 may be formed to have an outer diameter that is relatively smaller than the outer diameter formed by the needles formed on the disk needle 12 . Accordingly, the needle formed on the disk needle 12 may protrude further outward from the spacer 14 and pressurized to the skin.

The disk needle 12 and the spacer 14 may be freely rotatably installed on the shaft. A rotating shaft 16 is formed to protrude from both ends of the head unit 10 and is rotatably installed in the holder unit 20 .

In another embodiment, the head unit 10 may be formed of a stamp-type head unit.

As shown in Figure 1, the head portion 10 of this embodiment supports the needle plate 13 and the needle plate 13 in which a plurality of needles are uniformly arranged at intervals on the front side, and the holder portion 20 on both sides. ) may include a needle body 11 having a rotating shaft 16 that is shaft-coupled to the support portion.

In the case of this embodiment, by rotating the needle body 11 in the holder part 20 to direct the needle plate 13 toward the outlet 21 of the holder part, the solution is discharged to the needle of the needle plate 13. can be buried And, by simply rotating the needle body 11 again and using the needle plate 13 to face the skin, it can be used conveniently.

In addition, although not shown, the needle body 11 may be further formed with a hole through which the solution is moved through the needle plate 13 . Accordingly, without rotating the needle body, the solution discharged from the outlet of the holder can be supplied to the needle of the needle plate through the hole.

In this way, the apparatus can be used by simply replacing the roller-type head part or the stamp-type head part on the holder part 20 as needed.

Hereinafter, the needle assembly of this embodiment will be described as an example in which the roller-type head unit 10 is mounted.

The holder portion 20 extends outwardly from one end of the support portion 22 for rotatably supporting the head portion 10, and a fitting portion 24 that forms the other end and is detachably coupled to the body portion 30. ) may be included. The support part 22 and the fitting part 24 may be integrally formed to form one body.

As shown in FIG. 4 , an outlet 21 through which the solution is transferred through communication between the support part 22 and the fitting part 24 is formed inside the holder part 20 .

The support part 22 is a pair of members extending in the form of a fork to pivotally support both ends of the rotation shaft 16 of the head part 10 . Accordingly, the head portion 10 is coupled to the support portion 22 and rotates freely.

In this embodiment, the fitting portion 24 of the holder portion 20 may be mounted on the body portion 30 to form a square shape.

Concave portions or convex portions that engage with each other may be formed on the outer surface of the fitting portion 24 and the inner surface of the fitting groove portion 32 of the body portion 30 into which the fitting portion 24 is inserted. Accordingly, when the fitting portion 24 of the holder portion 20 is inserted into the fitting groove portion 32 of the body portion 30, the recessed portion and the convex portion may be engaged with each other to be more closely and firmly coupled.

An outlet 21 is formed through the center of the tip of the holder 20 . Accordingly, the solution introduced into the body 30 from the container 100 may be finally discharged to the outside of the holder 20 through the outlet 21 and supplied to the head 10 .

The holder part 20 of this embodiment may include a check valve 50 installed at the outlet 21 to discharge the solution of the body part 30 only toward the head part 10 . It is possible to discharge the solution in one direction only toward the head 10 through the check valve 50 and block the reverse flow in the opposite direction. Accordingly, it is possible to block external foreign substances such as blood, filth, and bacteria from the skin from flowing back into the body 30 during the procedure. Therefore, it is possible to prevent the solution from being contaminated by foreign substances.

As shown in FIG. 4 , the check valve 50 is made of an elastic material and is closely installed at the outlet 21 of the holder 20 , and the elastic membrane 52 , and a cutout formed in the elastic membrane 52 . (54) may be included.

The elastic film 52 may be an elastic material that is elastically deformed by an external force and returns to its original state when the external force is removed. The elastic film 52 may be formed of, for example, a material such as silicon or rubber.

The cut-out 54 is a portion in which the elastic membrane 52 is cut, and is opened while being spread outward. The cutout 54 may be formed in a straight or cross shape.

As shown in FIG. 4 , the elastic membrane 52 may have a structure formed to be convexly curved toward the holder part 20 in the direction in which the solution is discharged. Accordingly, when an external force is applied from the inside to the outside, the elastic membrane 52 expands to the outside, that is, toward the holder part 20 , and the cut-out part 54 is easily opened to the outside to discharge the solution. Conversely, when an external force is applied from the outside to the inside, the convexly curved elastic membrane 52 is not easily deformed inward, so that the cutout 54 does not open inward. Therefore, the cut-out portion 54 is kept in a closed state, so that foreign substances cannot be introduced into the inside.

In addition, the check valve 50 of this embodiment has a structure that can minimize the residual amount of the solution remaining inside the holder portion 20.

To this end, the check valve 50 of this embodiment includes a pair of flanges 56 integrally formed at intervals on the outer periphery of the elastic membrane 52 , so that the flange 56 is the outlet of the holder part 20 . (21) installed inside and outside, the holder 20 is formed with a step 58 on the inner surface of the outlet 21 on which the flange 56 is placed, the flange 56 and the outlet of the holder 20 (21) may have a structure in which the inner surface is located on the same plane.

That is, the height of the step 58 and the thickness of the flange 56 are formed to be the same, so even if the check valve 50 is installed at the outlet 21 of the holder 20, there is no difference in height due to the flange 56 as a whole. The inner surface of (20) forms a flat surface.

Therefore, all of the solution can flow toward the cutout 54 of the elastic film 52 without being caught on the flange 56 . Accordingly, it is possible to discharge and use all of the solution from the inside of the holder unit 20, thereby preventing the expensive solution from being used and wasting.

The holder part 20 having the above structure is provided in various ways according to the type of the head part 10 , and may be selectively mounted on the body part 30 to be used.

Although exemplary embodiments of the present invention have been illustrated and described as described above, various modifications and other embodiments may be made by those skilled in the art. All such modifications and other embodiments are intended to be contemplated and included in the appended claims without departing from the true spirit and scope of the present invention.
