Description

Dropper container without residue

Technical Field

An aspect of the present disclosure relates to a residue-free dropper container, and more particularly, to a residue-free dropper container that: when the dropper part and the container body are separated from each other, the dropper connector is elastically deformed such that the end of the dropper is brought into close contact with the inner bottom surface of the container body, thereby enabling a user to use up the contents of the container body without remaining.

Background

Cosmetics refer to articles for human bodies, which make human bodies neat and beautiful to make people fascinating and attractive in appearance, or to maintain or promote health of skin or hair.

These cosmetics are mainly classified into basic cosmetics, functional cosmetics, and color cosmetics according to their use purposes.

The functional cosmetics refer to cosmetics for whitening skin or removing wrinkles and protecting skin from ultraviolet rays.

However, since most of the above-mentioned functional cosmetics are very expensive, it is economical to provide a precise amount of cosmetics to the site to be treated. Conventionally, when cosmetics are used, the cosmetics are taken out to the palm of the hand, and the palm absorbs a large amount of the cosmetics, so that the expensive cosmetics are wasted.

In addition, since the functional cosmetics do not use preservatives, they are very susceptible to contamination. Therefore, if a user holds a general cream-like cosmetic by hand when using the cosmetic, or pours an emulsion-like cosmetic on the palm of the hand while the opening of the cosmetic container is in contact with the palm, contaminants on the hand may enter the main body of the cosmetic container to deteriorate the cosmetic.

Therefore, when a functional cosmetic is used, it is preferable to use a fixed amount of the cosmetic. If the amount of cosmetic is too much or too little, there is a side effect or no effect on the skin, and thus a container capable of extracting a precise amount of cosmetic is required.

In order to solve the above problems, a dropper type cosmetic container has been developed and used, in which a user can inhale cosmetics with a dropper and then drop the cosmetics to the skin to which the cosmetics are to be applied.

However, the conventional dropper type cosmetic container has inconvenience in that when a user uses cosmetics, the cap of the container needs to be opened to take out the cosmetics by pressing the button. In addition, since the amount of cosmetic introduced through the dropper varies according to the pressure applied to the button by the user, there is a problem in that it is difficult to discharge an accurate amount of cosmetic at the time of use.

In order to solve the above problems, the present applicant has filed and registered korean utility model registration No.20-0480441 entitled "automatic drip tube container". A conventional automatic pipette container includes: a container body for containing contents; a cap connected to the opening of the container body and having an inner cap and an outer cap; a pressing bag, one part of which is inserted into the cover and the other part of which protrudes from the top of the cover; a push tube connected to the press bag such that the push tube can move up and down in the cover and the press bag; the elastic piece is arranged outside the push pipe; and a dropping tube connected to the push tube to suck and discharge the contents contained in the container body.

However, according to the above-described conventional art, since the tip of the dropper is separated from the inner bottom surface of the container body, the contents may remain on the bottom surface of the container body after most of the contents in the container body are used. In order to use the remaining contents, a user needs to take out the contents using a dropper while tilting the container body to one side, which is inconvenient. Moreover, there is still a problem that some contents remain in the container main body, though.

In order to solve the above problems, korean patent registration No.10-1890816 discloses a "dropper type container", wherein the dropper type container includes: a container body accommodating contents and having an open upper portion; a cover connected to the inlet portion of the container body and having an inner cover and an outer cover; a pressing part, a portion of which is inserted into the cap and another portion of which protrudes from the top of the cap; a bellows bag, an upper portion of which is pressed by the pressing portion, and which is supported by the inner lid; and a dropper connected to a lower portion of the bellows bag to suck or discharge the contents contained in the container body, wherein the dropper extends from an entrance portion to a bottom of the container body.

However, according to the above-described conventional art, the corrugated bag is completely brought into close contact with the contents discharge prevention member when the container body is coupled with the cover, so that the contents remaining on the inner circumference of the contents discharge prevention member or the contents passing through the contents discharge prevention member may be brought into contact with the surface of the corrugated bag. Therefore, the contents on the surface of the corrugated bag flow down to soil the periphery or be contaminated by external foreign materials during use, which may cause a sanitary problem.

In addition, according to the above conventional art, since the dropper is attached to the end of the bellows bag made of the elastic material, there is a problem in that: when the dropper is inserted into or removed from the container body or when the dropper is in contact with the skin, the dropper is bent from the inner cap to one side due to an external force, which is inconvenient to use.

Hereinafter, a residue-free dropper container according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of a dropper container according to an embodiment of the present disclosure, fig. 2 is an exploded perspective view of a dropper container according to an embodiment of the present disclosure, and fig. 3 is an exploded sectional view of a dropper container according to an embodiment of the present disclosure.

As shown, the residue-free dropper container according to the embodiment of the present disclosure may include a container body 10 and a dropper part 30, wherein the dropper part 30 may include an inner cap 40, an outer cap 50, a dropper connector 60, a dropper 70, and a button 80.

The container body 10 may have a rigid cylindrical shape and may constitute the appearance of a dropper container. The container body 10 may not be limited to a rigid cylindrical shape, and may be formed in various shapes using various materials according to the type, usability, or design factor of the stored material therein. However, since it is necessary to insert a dropper 70 of a predetermined length into the container body 10, it is preferable that the container body 10 be narrow in width and relatively long in length.

The liquid or gel cosmetic may be contained in the container body 10, and as shown in fig. 2, an inlet portion 12 may be formed at one side of the container body 10 such that the contents can be filled and the dropper 70 of the dropper part 30 can be inserted through the inlet portion 12. A screw thread may be formed on the outer circumference of the inlet portion 12 of the container body 10 to fasten with the dropping pipe portion 30.

Meanwhile, a hollow blade 20 having opened upper and lower portions may be connected to the inside of the inlet portion 12 of the container body 10. The wiper blade 20 may be in close contact with the outer surface of the dropper 70 of the dropper part 30, and when the dropper 70 is separated from the container body 10, the wiper blade 20 may wipe off the cosmetic material from the outer circumference of the dropper 70, so that the dropper 70 may be sanitarily used. As shown in fig. 3, the wiper 20 may include a mounting jaw 22 mounted on the inlet portion 12 of the container body 10, a close contact portion 24 closely contacting the outer circumference of the dropping pipe 70, and a sidewall 26 connecting the mounting jaw 22 and the close contact portion 24. The mounting jaw 22 may be mounted at the upper end of the entrance portion 12 of the container body 10, the close contact portion 24 may be inclined inward from the sidewall 26 to scrape off the contents from the outer surface of the dropping pipe 70, and the sidewall 26 may be fitted into the inner circumferential surface of the entrance portion 12 of the container body 10.

A portion of the drip tube part 30 may be inserted into the container body 10, and the remaining portion may be fastened to the upper portion of the container body 10, so that the contents contained in the container body 10 may be sucked or discharged according to the user's manipulation. In this case, the fastening or releasing between the container body 10 and the dropping pipe portion 30 may be performed simultaneously with the automatic suction or discharge process of the contents by the dropping pipe portion 30.

As shown in fig. 2, the dropper portion 30 may include an inner cap 40, an outer cap 50, a dropper connector 60, a dropper 70, and a button 80. Hereinafter, a specific structure of the dropper part 30 will be specifically described with reference to the drawings.

An inner cap 40 according to embodiments of the present disclosure may be secured to the container body 10 and secure the drip tube connector 60 and the button 80 in association with the outer cap 50. In this case, it is preferable that the inner lid 40 has a hollow cylindrical shape so that the dropping tube 70 can pass through.

As shown in fig. 3, the inner lid 40 may include a fastening portion 42, a mounting portion 44 extending inwardly from the fastening portion 42, and an insertion portion 46, the insertion portion 46 extending downwardly from the mounting portion 44 and being inserted into the inlet portion 12 of the container body 10.

The fastening portion 42 of the inner lid 40 may be a portion detachably connected to the entrance portion 12 of the container body 10, and a screw thread may be formed at an inner circumference of the fastening portion 42 to be screw-fastened with the screw thread formed in the entrance portion 12 of the container body 10. The container body 10 and the inner cap 40 may be coupled to each other by various coupling methods other than the screw coupling method, as long as the container body 10 and the inner cap 40 can be stably and firmly coupled to each other and can be easily separated from each other. In addition, the outer wall 48 may extend vertically at an upper portion of the fastening portion 42 (i.e., an opposite side of the fastening portion 42 with respect to the mounting portion 44), and at least a portion of the drip tube connector 60 and the button 80 may be inserted and received in the outer wall 48.

The mounting portion 44 of the inner lid 40 may be configured to horizontally extend to be connected between the fastening portion 42 and the insertion portion 46, one side of the mounting portion 44 may be mounted on the upper end of the inlet portion 12 of the container body 10 or the upper end of the mounting jaw 22 of the wiper blade 20, and the dropper connector 60 may be mounted on the other side of the mounting portion 44. In this case, it is preferable that the connection portion between the mounting portion 44 and the insertion portion 46 is configured as a smooth curved surface.

The insertion portion 46 of the inner lid 40 may be spaced apart by a predetermined interval toward the inside of the fastening portion 42 and extend downward, and an anti-shake portion 46a may be formed on the inside of the insertion portion 46. The anti-shake portion 46a may be configured to protrude from an inner circumference of an end portion of the inner lid 40 toward a center thereof and may be in close contact with an outer circumference of the drop tube 70. The anti-shake portion 46a may be formed along the outer circumference of the inner cover 40 facing the surface of the drop tube 70, and preferably, the anti-shake portion 46a is configured as an annular protrusion. Therefore, the dropper 70 can be stably fixed without being bent or shaken to one side when the dropper 70 is inserted into the container body 10 or separated from the container body 10, and when the dropper 70 is extracted from the container body 10 for use. That is, since the drip tube 70 is connected to the lower portion of the drip tube part 30 by the drip tube connector 60 made of an elastic material, there is a problem in that the drip tube 70 is easily bent or shaken by an external force. For this reason, the shaking prevention part 46a is provided at the end of the inner lid 40 to hold the outer surface of the drop tube 70, thereby solving the problems of durability and instability of the drop tube 70 that is bent or shaken by an external force when used.

Meanwhile, at least one straight hole may be formed in the insertion portion 46 in the longitudinal direction of the drop tube 70.

The outer cap 50 according to an embodiment of the present disclosure may be fixedly coupled to the outside of the inner cap 40 while completely surrounding the inner cap 40, and may be used as a handle for using or operating the drip tube part 30. A through hole 52 may be formed in the upper middle portion of the outer cover 50, and at least a portion of the button 80 may be exposed to the outside through the through hole 52.

The dropper connector 60 according to an embodiment of the present disclosure may be composed of an elastic material, and may be elastically deformed by the dropper 70 at the inside of the inner lid 40. The dropper connector 60 may be connected to a lower portion of the button 80 to block an open lower portion of the button 80, and, at the same time, connected to the dropper 70 and the button 80.

The dropper connector 60 may include an adaptation part 62 adapted to the button 80, an elastic deformation part 64 extending from the adaptation part 62 and elastically deformable in shape, and a connection part 66 extending downward from the elastic deformation part 64 and connected to the dropper 70. Since the dropper connector 60 has a structure that is deformable when pressed by the dropper 70, it is preferable that the dropper connector 60 is constructed in a funnel shape with a hole in the center of the lower portion, as shown in fig. 2. The shape of the dropper connector 60 is not limited to the above shape, and the shape may be variously changed according to the connection structure or deformation manner of the button 80 and the dropper 70.

The fitting portion 62 of the drip tube connector 60 may be connected to an outer lower portion of the button 80 and inserted into the outer wall 48 of the inner cover 40, and the elastic deformation portion 64 may be configured to have a smooth curved shape corresponding to a connection portion between the mounting portion 44 and the insertion portion 46 of the inner cover 40. In addition, a coupling groove 66a may be formed on an inner circumference of the coupling portion 66 such that a coupling protrusion 76 formed on an upper outer circumference of the drip tube 70 may be coupled in the coupling groove 66a, and an air flow hole 66b may be formed at a center of the coupling portion 66 such that air inside the drip tube portion 30 may flow through the air flow hole 66b.

In this case, the elastic deformation portion 64 of the dropper connector 60 may be maintained in contact with the inner circumference of the inner cap 40 and then elastically deformed when pressed by the dropper 70, so that the elastic deformation portion 64 may be spaced apart from the inner circumference of the inner cap 40. That is, the fitting portion 62 of the dropper connector 60 may be fixedly fitted between the inner cap 40 and the outer cap 50 in a state where the fitting portion 62 of the dropper connector 60 is connected to the button 80, and the connection portion 66 may be raised by pressing the dropper 70 against the inner bottom of the container body 10, and at the same time, the elastic deformation portion 64 may be raised into the inner space of the button 80 while being elastically folded.

A dropper 70 according to an embodiment of the present disclosure may be connected to one side of the dropper connector 60 to extend downward of the dropper part 30. The dropper 70 may be configured to suck or discharge the contents according to the change in the inner volume of the button 80 caused by the elastic deformation of the dropper connector 60 or the direct pressurization of the button 80. The dropping pipe 70 may extend through the centers of the inner cap 40 and the wiper blade 20 when being coupled to the container body, and the outer surface of the dropping pipe 70 may be in close contact with the anti-shaking portion 46a of the inner cap 40 and the close contact portion 24 of the wiper blade 20.

A suction port 72 may be formed at an end of the drop tube 70, and the contents may be sucked or discharged through the suction port 72. As shown in fig. 2, an air intake hole 74 for introducing the contents contained in the container body 10 may be formed in a side wall of the drop tube 70 adjacent to the suction port 72, so that the contents contained in the container body 10 can be easily sucked or discharged even when the end of the drop tube 70 is completely brought into close contact with the inner bottom surface of the container body 10. The dropper 70 may be made of a glass material such that the dropper 70 may have an externally visible tubular shape with both sides open and the inside empty, although the present disclosure is not limited thereto. The dropper 70 may be made of different materials according to the type, usability, durability and design factors of the cosmetic product sucked into the inside.

As shown in fig. 3, at least a portion of the dropper 70 may be inserted into the container body 10 by passing through the inlet portion 12 of the container body 10, and one end of the dropper 70, that is, an edge portion of the suction port 72 may be in contact with the bottom surface of the container body 10. The end of the dropper 70 may be maintained in close contact with the bottom surface of the container body 10 by the elastic deformation of the dropper connector 60 during the fastening or releasing of the connection between the dropper part 30 and the container body 10. Therefore, when the dropping pipe part 30 and the container body 10 are separated and the contents are automatically sucked at the same time, the dropping pipe 70 can easily suck the remaining contents at the bottom of the container body 10. More specifically, when the dropper 70 of the dropper part 30 is inserted into the container body 10, the end of the dropper 70 may be pressed against the inner bottom surface of the container body 10, and at the same time, the dropper connector 60 may be elastically deformed such that the inner volumes of the button 80 and the dropper connector 60 may be reduced to discharge the contents stored therein, and when the dropper 70 is removed from the container body 10, the compressed dropper connector 60 is restored, and the end of the dropper 70 may be held in close contact with the inner bottom surface of the container body 10 by the elastic force of the dropper connector 60, and at the same time, the inner volumes of the button 80 and the dropper connector 60 are increased such that the contents in the container body 10 may be introduced into the dropper 70.

The opposite side of the suction port 72 of the dropper 70 may be open and may be connected to the inner space of the button 80 through the air flow hole 66b of the dropper connector 60.

A button 80 according to embodiments of the present disclosure may be connected to the dropper connector 60 to draw in or expel the contents with pressure applied thereto.

The button 80 may include a pressing part 82 exposed to the outside through the through hole 52 of the outer cap 50 and pressed by a user, and a connecting part 84 extending from an end of the pressing part 82 and fixedly connected to the dropper connector 60. The connection portion 84 is preferably inserted into the inside of the outer cap 50 while being expanded outward from the end of the pressing portion 82 to stabilize the connection. In this case, the button 80 and the drip tube connector 60 may be fixedly fitted between the inner cap 40 and the outer cap 50 in a state of being connected to each other.

Meanwhile, the dropper connector 60 and the button 80 may be made of an elastic material so that the shape thereof can be easily deformed by compression and restoration. The dropper connector 60 and the button 80 may be made of a thermosetting resin, which may include at least one of epoxy resin, amino resin, phenolic resin, and polyester resin, or a thermoplastic resin, which may include at least one of polyethylene, acrylic resin, polypropylene, polystyrene, polyvinyl chloride, teflon, nylon, and polyoxymethylene resin. In particular, most preferably, the drip tube connector 60 and the button 80 are made of Elastomer based thermoplastic Elastomer (TPE). The materials of the dropper connector 60 and the button 80 may not be limited to the above materials, and may be made of various materials as long as they have predetermined elasticity.

Fig. 4 to 8 are diagrams illustrating use of a residue-free dropper container according to an embodiment of the present disclosure, and a method of using the residue-free dropper container according to the embodiment of the present disclosure will be described with reference to the drawings.

Fig. 4 is a sectional view illustrating an operation of releasing fastening of a container body and a dropper part according to an embodiment of the present disclosure, fig. 5 is a sectional view illustrating an operation of detaching the dropper part from the container body according to an embodiment of the present disclosure, fig. 6 is a sectional view illustrating an operation of using contents by discharging the contents from the dropper part according to an embodiment of the present disclosure, fig. 7 is a sectional view illustrating an operation of inserting the dropper of the dropper part into the container body according to an embodiment of the present disclosure, and fig. 8 is a sectional view illustrating an operation of fastening the container body and the dropper part according to an embodiment of the present disclosure.

In order to use the residue-free dropper container according to an embodiment of the present disclosure, as shown in fig. 4, the fastening between the container body 10 and the dropper part 30 is released by rotating the outer cap 50 from the container body 10 in either direction.

In this way, when the fastening between the container body 10 and the dropper part 30 is released, the elastic deformation part 64 of the compressed dropper connector 60 is elastically restored and the internal volume between the button 80 and the dropper connector 60 is increased, so that the contents in the container body 10 are introduced through the suction port 72 of the dropper 70. In this case, the dropper connector 60 pushes the dropper 70 toward the bottom of the container body 10 by the elastic force such that the end of the dropper 70 is held in close contact with the inner bottom surface of the container body 10.

Thereafter, as shown in fig. 5, the dropper portion 30 is separated from the container body 10, and as shown in fig. 6, the content is discharged from the dropper 70 by pressing the button 80. In this case, since the anti-shaking portion 46a formed in the inner lid 40 of the drop tube portion 30 is in close contact with the outer circumference of the surface of the drop tube 70, the drop tube 70 can be stably fixed without being bent or shaken to one side.

After makeup is completed, as shown in fig. 7, the dropper 70 of the dropper part 30 is inserted into the inlet portion 12 of the container body 10, and as shown in fig. 8, the dropper part 30 is fastened to the container body 10 by rotating the outer cap 50 of the dropper part 30.

Thus, when the dropper portion 30 is inserted and fastened into the container body 10, the end of the dropper 70 is pressed against the inner bottom surface of the container body 10. In this case, the connection portion 66 of the dropper connector 60 is pushed up by the dropper 70, so that the elastic deformation of the elastic deformation portion 64 of the dropper connector 60, and at the same time, the inner volume of the button 80 and the dropper connector 60 is reduced, so that the contents stored therein are discharged to the inside of the container body 10.

Claims

1. A residue-free dropper container, comprising:

a container body having contents therein and formed with an inlet portion; and

a dropping-pipe part for sucking and discharging the contents contained in the container main body,

wherein the dropping pipe portion includes: an inner cap secured to the container body; an outer cap coupled to an exterior of the inner cap; an elastomeric drip tube connector fixedly connected between the inner cap and the outer cap; a dropper connected to one side of the dropper connector and having a suction port formed at an end thereof; and a button connected to the dropper connector to suck or discharge the contents with pressure applied thereto, and

when the container body and the dropper part are separated from each other, at least a portion of the dropper connector is elastically deformed such that the end of the dropper is in close contact with the inner bottom surface of the container body, and an anti-shaking part protrudes from the inside of the inner cap to prevent shaking of the dropper.

2. The residue-free dropper container of claim 1 wherein a wiper is formed at the entrance portion of the container body to clear contents from a periphery of the dropper.

3. The residue-free dropper container of claim 1 wherein the inner lid comprises a securing portion, a mounting portion extending inwardly from the securing portion, and an insertion portion extending downwardly from the mounting portion and inserted into the inlet portion of the container body.

4. The residue-free dropper container according to claim 1, wherein the anti-shaking portion is configured to protrude from an inner circumference of an end portion of the inner cap to a center of the inner cap to be in close contact with an outer circumference of the dropper.

5. The residue-free dropper container of claim 1, wherein a through hole is formed in the outer cap such that at least a portion of the button is exposed to the outside through the through hole.

6. The residue-free dropper container of claim 1, wherein the dropper connector comprises an adaptation portion adapted to the button, an elastically deformable portion extending from the adaptation portion and elastically deformable in shape, and a connection portion extending downward from the elastically deformable portion and connected to the dropper.

7. The residue-free dropper container of claim 6, wherein the elastically deformed portion of the dropper connector maintains contact with an inner circumference of the inner lid and is spaced apart from the inner circumference of the inner lid as the elastically deformed portion elastically deforms when pressed by the dropper.

8. The residue-free dropper container of claim 1, wherein an air intake hole is formed in an end side wall of the dropper, and the contents received in the container body are introduced using the air intake hole.

9. The residue-free dropper container of claim 1 wherein the button and the dropper connector are fixedly fitted between the inner cap and the outer cap in a state of being connected to each other.

10. The residue-free dropper container of claim 1, wherein when the dropper of the dropper part is inserted into the container body, an end of the dropper is pressed against a bottom surface of the container body, and at the same time, the dropper connector is elastically deformed such that an inner volume of the button and the dropper connector is reduced to discharge the contents stored therein, and when the dropper leaves the container body, the dropper connector compressed is restored such that an inner volume of the button and the dropper connector is increased to supply the contents in the container body into the dropper.
