Description

[Correction according to Rule 26, 31.08.2018] Cosmetic container with pump

The present invention relates to a cosmetic container having a pump.

The cosmetic container having the pump can be used in a form in which the contents are discharged to the outside by pushing the pump head exposed to one side of the body in which the contents are accommodated. Such a cosmetic container may include an overcap serving as a lid to prevent contamination of the pump head and the cosmetic dispenser.

Generally, the overcap is provided so that it can be selectively fixed to the one end of the main body to which the pump head is provided by hook engagement or fitting. In this case, the joint portion between the overcap and the main body may be deformed or damaged by frequent use, and if the joint portion is deformed or damaged, the coupling strength between the overcap and the main body may weaken, .

In addition, since the conventional pump head is composed of only one body, it is very difficult to manufacture a high-quality container using a release material in which a plastic material and a metal material are combined with each other.

Embodiments of the present invention have been proposed in order to solve the above problems and provide a cosmetic container having a pump capable of maintaining a long coupling force between the overcap and the main body by fixing the overcap to the main body using magnetic force .

Further, even if a magnetic force is used to fix the overcap, the pump head itself of the release material can be prevented from being disassembled and the pump head can be prevented from being separated from the main body in the situation where the magnetic force acts, And to provide a cosmetic container having a pump capable of easily installing a permanent magnet in an overcap.

According to an aspect of the present invention, there is provided a pump head comprising: an inner pump head portion enclosing an outer pump head portion; A pump for supplying the contents to the discharge passage structure of the inner pump head portion; A body coupled to the pump; An overcap detachably attached to the body by a magnetic force; And a plurality of permanent magnets coupled to the pump head and the overcap.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view of a cosmetic container having a pump according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line A-A shown in FIG. 3 is an enlarged cross-sectional view of the circle B shown in Fig. 2, and Fig. 4 is an exploded perspective view of the overcap and pump head of the cosmetic container having the pump shown in Fig.

1 to 4, the cosmetic container 10 having the pump according to the present embodiment is an airless pump capable of simultaneously solving the environmental problems due to the harmfulness of the gas affecting the human body and the discharge of the carbon dioxide. As shown in Fig. Here, the airless pump may be abbreviated as a pump 240 described later.

The cosmetic container or container product according to the present embodiment includes a main body 200 containing the contents C and coupled with the pump 240 and an overcap which is magnetically detachably attached to the main body 200 to completely shield the upper portion thereof 100).

The overcap 100 is made of one of an opaque material, a translucent material, and a transparent material using plastic or a metal material.

When the pump head 250 is pressed downward, the pump 240 can generate a pressure capable of discharging the contents to the outside of the main body 200 by the pump 240.

The pump head 250 may be formed of a release material, and may be manufactured in a separated form and then assembled by assembling. For example, the pump head 250 may include an inner pump head portion 252 and an outer pump head portion 258. Here, the inner pump head portion 252 may be formed of a plastic material. On the other hand, the outer pump head portion 258 may be formed of a thin metal plate material.

The outer pump head portion 258 covers the outer and upper surfaces of the inner pump head portion 252 except for the sliding projection portion 251 of the inner pump head portion 252.

When the outer pump head portion 258 is formed of a thin metal plate material, it is more durable than a simple metal coating, is very strong against scratches, and can exhibit a product characteristic that the outer surface of the pump head 250 is very beautiful .

In this way, the pump head 250 of the release material is made of a plastic material and most of the outer surface of the inner pump head portion 252, which is easy to be injection-molded, is closed by the outer pump head portion 258, The effect can be demonstrated.

According to the present embodiment, the inner pump head portion 252 is surrounded by the outer pump head portion 258, and

permanent magnets

120 and 257 are provided to the main body 200 and the overcap 100.

The

permanent magnets

120 and 257 may be paired or plurally arranged so as to face each other to mutually interact with magnetic force. The

permanent magnets

120 and 257 are coupled to the pump head 250 and the overcap 100.

The

permanent magnets

120 and 257 include a first permanent magnet 257 interposed between the inner pump head portion 252 and the outer pump head portion 258 and a first permanent magnet 257 interposed therebetween And includes a second permanent magnet 120 installed on the overcap 100 so as to face each other.

An unshown adhesive or double-sided adhesive tape may be further provided on the upper edge of the first permanent magnet 257 and the upper edge of the first magnet seating groove 253 to allow the outer pump head portion 258 to communicate with the inner pump It may be completely fixed to the head portion 252.

The outer side surface of the inner pump head portion 252 is formed as a tapered surface having a larger diameter of the inner pump head portion 252 as it goes downward, without using an adhesive or a double-sided adhesive tape. On the other hand, the outer pump head portion 258 may have the same diameter as the closed top portion and the open bottom portion, respectively.

Accordingly, the outer pump head portion 258 can be coupled to the inner pump head portion 252 in a forced fit manner, and even if there is no separate fixing means such as an adhesive, And the outer surfaces of the protrusions 252 can be closely contacted and fixed.

In addition, a gap G may be provided between the first permanent magnet 257 and the second permanent magnet 120. Here, the gap G refers to a space between the ceiling surface inside the overcap 100 and the upper surface of the pump head 250.

Therefore, even if the overcap 100 is engaged or covered as if covering the upper part of the main body 200, the ceiling surface inside the overcap 100 is not in contact with the upper surface of the pump head 250 by the gap G can do.

The interval between the gaps G can be determined within a range in which the overcap 100 can be brought into close contact with the main body 200 by a magnetic force (e.g., attractive force) pulling each other between the

permanent magnets

120 and 257 , And may not be limited to a specific value.

The inner pump head portion 252 of the pump head 250 includes a first magnet seating groove 253 formed on the upper portion of the inner pump head portion 252. At this time, the first permanent magnet 257 which is seated in the first magnet mounting groove 253 can be shielded by being enclosed by the outer pump head portion 258.

Particularly, in the skirt portion of the inner pump head portion 252, one hole 254a of the discharge passage structure 254 is opened.

A through hole 259 is formed in the outer pump head portion 258 with reference to a position corresponding to the one hole 254a.

The outer pump head portion 258 is a metal cap type structure having a lower end opened and an upper end closed and a through hole 259 formed in the wall between the lower end and the upper end.

The outer pump head portion 258 is coupled to the inner pump head portion 252 in a downward direction at the upper portion of the inner pump head portion 252. At this time, the bottom surface of the outer pump head portion 258 can be brought into close contact with the upper surface of the first permanent magnet 257. The through hole 259 of the outer pump head portion 258 and the one hole 254a of the outer pump head portion 258 can be matched with each other.

The nozzle unit 290 is formed in a tubular shape capable of performing a nozzle function. The nozzle unit 290 may be a pump discharge port. The nozzle portions 290 can be inserted into the through holes 259 and the one-side holes 254a which are mutually coincident and overlap each other in an interference fit manner.

At this time, the nozzle unit 290 may serve as a fixing pin for preventing the outer pump head unit 258 and the inner pump head unit 252 from being separated or disassembled. Therefore, even if the magnetic force or the external force of the first permanent magnet 257 acts on the pump head 250, the outer pump head portion 258 is not disassembled from the inner pump head portion 252 by the nozzle portion 290 .

Since the

permanent magnets

120 and 257 are mounted on the overcap 100 and the pump head 250 while maintaining the gap G, the user can open the overcap 100 and remove the overcap 100 from the main body 200 The interference between the top surface of the pump head 250 and the ceiling surface of the inside of the overcap 100 is not generated even when the overcap 100 is pulled in the oblique direction other than the vertical direction, It is possible to prevent the pump 240 from malfunctioning.

If the overcap 100 and the pump head 250 are brought into close contact with each other only for the purpose of magnetic force operation, the user can grasp the overcap 100 and peel it off obliquely, The inner ceiling of the pump head 250 may be slightly depressed downwardly on the pump head 250. This may cause the disadvantage that the contents C can be discharged when the pump 240 is operated.

However, in the present embodiment, due to the gap G, it is possible to prevent the pump 240 from malfunctioning when the overcap 100 is opened and to prevent the user from easily moving the overcap 100 from the main body 200 It is possible to exhibit the advantage of being separated.

As described above, the body 200 and the overcap 100 can reliably realize the overcap assembly structure of the magnetic specification that can be mutually detachable by the magnetic force of the

permanent magnets

120 and 257.

The overcap 100 includes a cap body 110, a second magnet seating groove 111, a finishing plate seating portion 112, a magnet fixing protrusion 113, and a finishing plate 130.

The cap body 110 has a lower end closed to cover the upper part of the main body 200 and a closed upper end.

A second magnet seating groove 111 for receiving the second permanent magnet 120 is formed at the closed top of the cap body 110.

The magnet fixing protrusion 113 is formed on the inner surface of the second magnet mounting groove 111 to fix the second permanent magnet 120 to the second magnet mounting groove 111.

The second permanent magnet 120 can be firmly fixed to the bottom surface of the second magnet mounting groove 111 by an unmarked adhesive or double-sided adhesive tape.

The finish plate seating portion 112 is disposed on the upper portion of the second magnet seating groove 111 so as to form a step by a relatively larger diameter than the second magnet seating groove 111. [

The finishing plate 130 can be coupled to the finishing plate seating portion 112 in a forced or double ejection manner and shields the open upper portion of the second magnet seating groove 111 and the finishing plate seating portion 112 .

At this time, a space 114 may be provided between the bottom surface of the finishing plate 130 and the upper surface of the second permanent magnet 120.

The space portion 114 of the cap body 110 permits deformation of the finishing plate 130 within an elastic range so that the finishing plate 130 can exhibit the shock absorbing function.

The space 114 may be used as a space in which an additional permanent magnet may be installed, or may be used as a space in which a permanent magnet (not shown) having a different thickness is provided to adjust the magnitude of the magnetic force.

The pump head structure includes a nozzle unit 290 serving as a fixed pin and a member for discharging the contents to prevent disassembly of the pump head 250 or separation of the pump head from the pump 240, An outer pump head portion 258 and an inner pump head portion 252, which can be mutually fixed by means of an inner pump head portion 258, are provided.

The cosmetic container 10 of the present embodiment is a device capable of storing the contents C filled in the inner space of the inner container 230 such as cosmetics and being able to dispense or dispense in a fixed quantity. And the present embodiment can be applied even in the case of other contents such as liquid or mucilage.

The present embodiment can provide an outer container 210, an intermediate container 220 and an inner container 230 made of any one of opaque material, translucent material and transparent material. For example, the outer container 210, the intermediate container 220, and the inner container 230 are made of any one of materials such as metal, plastic, synthetic resin, and glass.

When the outer container 210, the intermediate container 220, and the inner container 230 are all made of a transparent material or a translucent material, the kind of the content C, the charged amount, the remaining amount, and the like can be confirmed through the user's time . Alternatively, if only the outer container 210 is made of a transparent material (such as glass, crystal, transparent plastic, etc.) and the intermediate container 220 or the inner container 230 is made of an opaque material, . &Lt; / RTI >

The present embodiment is also similar to the design of the

base portions

221 and 211 and the wave-like bottom portion 212 of the ampoule design through the coupling between the outer container 210, the intermediate container 220 and the inner container 230 It is possible to provide a user with a high-quality container product having an element.

A hollow extension portion 223 is formed at the lower portion of the base portion 221 of the intermediate container 220 so as to be connected to the wavy bottom portion 212 naturally.

Since the hollow extension portion 223 is formed with the vent hole 222, the outside air can be introduced into the intermediate container 220 through the vent hole 222 and the operation of the pump 240 can be smoothly performed .

Particularly, a bead portion 233 is formed to protrude upward from the upper surface of the inlet 232 of the inner container 230.

A sealing portion 280 is provided between the upper portion of the bead portion 233 and the bottom surface of the fastening and fixing protrusion 243 of the pump 240. The sealing portion 280 serves to prevent the contents C from flowing out to the outside of the inner container 230.

The sealing part 280 is formed in an O-ring shape and can serve as a gasket formed of fluoro elastomers. For example, the sealing portion 280 may be made of any one material selected from the group consisting of epichlorohydrin polymer, ethylene propylene monomer (EPM), ethylene propylene diene monomer (EPDM), and hydrogenated nitrile butadiene rubber (HNBR) .

When the pump 240 is assembled to the inner container 230, the bead portion 233 can press the bottom surface of the sealing portion 280 to increase the contact area therebetween. Further, the sealing portion 280 can be hermetically sealed By the contact, the sealing performance can be maximized.

The pump inner cap 260 is engaged with the first fastening portion 261 of the inner container 230 in a state in which the fastening fastening protrusion 243 of the pump 240 is covered. The first fastening part 261 couples the inner cap 260 and the inner container 230 with each other by an undercut projection and a groove method.

The

bottom portions

221 and 211 corresponding to the closed lower ends of the outer container 210 and the intermediate container 220 can be visually distinguishable as an upper light-tight shape or an ampoule-like design.

The combination of the shapes of the wavy bottom portion 212 and the

base portions

221 and 211 allows the intermediate container 220 to be provided in a luxurious wine glass shape inside the outer container 210.

The wavy bottom portion 212 facilitates the upright storage and management of the cosmetic container according to the present embodiment by realizing line contact rather than surface contact with the reference surface even if there is a foreign substance on the reference surface on which the cosmetic container is placed.

This has a functional characteristic far beyond simply expressing the container shape with a curved surface, and it can exhibit differentiating from existing products. The

bottom portions

221 and 211 corresponding to the closed lower end of the intermediate container 220 functionally move the lower end protrusion 231a of the piston 231 protruding downward from the opened bottom of the inner container 230 to the bottom portion The piston head portion 231c which hermetically contacts the inner circumferential surface of the inner container 230 when filling or storing the contents C is filled in the inner space 221a of the inner container 230, The lower end projecting portion 231a of the piston 231 can be stopped and supported so as not to escape out of the opened lower end portion of the inner container 230 by the pressure.

The piston 231 is moved downward relative to the center of the piston 231 in correspondence with the spacing distance between the open lower end of the inner container 230 and the inner surfaces of the

base portions

221 and 211 of the intermediate container 230 And a lower protrusion 231a protruded from the lower protrusion 231a.

The piston 231 is connected to an upper portion of the lower protruding portion 231a and includes a hollow receiving portion 231b for receiving the lower end portion of the pump 240. [

The piston 231 is connected to the hollow accommodating portion 231b and surrounds the hollow accommodating portion 231b so that the piston 231 can move in the vertical direction by the discharge amount of the contents C due to the pumping of the pump 230. [ And a piston head portion 231c that is in sliding contact with the inner circumferential surface of the piston 230 in a sliding manner.

The hollow accommodating portion 231b of the piston 231 includes a bottom portion at the same level as the lower end of the piston head portion 231c and the opposite side of the bottom portion thereof is opened, Can be accommodated.

In this way, the piston 231 can position the piston head 231c at the bottom dead center of the inner vessel 230 in accordance with the filling or storage of the contents C, 230 at the top dead center position. At this time, since the hollow accommodation portion 231b of the piston 231 relatively receives the lower end portion of the pump 240, as a result, the top dead center position of the piston 231 becomes the maximum position, The contents C of the contents C can be discharged to the maximum without any remaining amount and the filling amount of the contents C relative to the inner container 230 can be relatively increased.

The pump 240 serves to supply the contents C of the inner container 230 to the discharge passage structure 254. [ The discharge passage structure 254 is disposed on the ceiling side of the inside of the inner pump head portion 252.

The discharge passage structure 254 may be a rectangular pipe. For example, one hole 254a of the discharge passage structure 254 may extend in the horizontal direction and may be opened at the side of the pump head 250.

The other hole 254b of the discharge passage structure 254 extends vertically so as to penetrate through the one hole 254a and opens downwardly of the pump head 250.

The lower part of the discharge passage structure 254 in which the other hole 254b is formed is inserted into the inner pipe 241 of the pump 240 and is coupled to the inner pipe 241 through each other.

The other hole 254b of the discharge passage structure 254 can be connected to the inner diameter of the inner pipe 241 in a space so as to be a discharge path for the contents C. [ The contents C introduced into the other hole 254b can be discharged to the outside of the pump head 250 via the one hole 254a of the discharge passage structure 254 and the nozzle portion 290. [

The pump head 250 is first coupled to the inner pipe 241 and is secondarily coupled to the pump outer cap 270 so that the pump 240 can not be detached from the main body 200 only by the operation and the magnetic force of the pump 240. The pump outer cap 270 is coupled to the outside of the pump inner cap 260 by an undercut projection and a groove type second fastening portion 272 while the pump inner cap 260 is being wrapped.

For example, an undercut groove portion 256 is formed on the outer surface of the lower portion of the discharge passage structure 254 for primary bonding. An undercut protrusion 242 is formed on the inner circumferential surface of the inner pipe 241 to be engaged with the undercut groove 256.

Since the undercut trench 256 and the undercut protrusion 242 are mutually fastened together by a coupling, a fastened state is obtained which is difficult to separate in the vertical direction.

A sliding protrusion 251 protruding outwardly and extending in the circumferential direction is formed at the lower end of the skirt portion of the inner pump head portion 252 of the pump head 250 for the secondary coupling.

A stop protrusion 271 is formed on the inner circumferential surface of the pump outer cap 270 so as to be coupled to the sliding protrusion 251 and extending in the inward direction and extending in the circumferential direction.

When the pump head 250 is inserted into the open upper portion of the pump outer cap 270, the sliding protrusion 251 and the stop protrusion 271 are slidably coupled in a sliding pair relationship, The pump head 250 is allowed to move downward but restricts the pump head 250 from being separated from the pump outer cap 270 in the upward direction. I am responsible.

A guide groove 273 is formed at one side of the opened upper portion of the pump outer cap 270 so as to have a width and a vertical length that can move the nozzle unit 290 in the vertical direction when the pump 240 operates. The upper portion of the guide groove 273 is opened to allow the coupling ditch nozzle portion 290 of the pump head 250 and the pump outer cap 270 to pass therethrough.

A cutout 274 is formed on the other side of the open top of the pump outer cap 270 to receive a user's finger for manipulation of the pump 240.

According to the cosmetic container 10 having the pump of the present invention as described above, since the overcap 100 is formed by the magnetic force between the plurality of

permanent magnets

120 and 257 provided in the pump head 250 or the overcap 100, The main body 200 can be easily attached and detached.

In particular, the

permanent magnets

120 and 257 are characterized by being provided in the pump head 250 or the overcap 100 which is configured to be decomposable. This characteristic is compared with the method of mounting the magnetite by the double injection, and after the position of the magnetite is changed by the flow pressure of the double screw, it is fixed in the changed state according to the completion of the injection, It is possible to solve the problem that a difference occurs in each product.

Then, the user can separate the overcap 100 from the main body 200 to use the cosmetic container 10.

Since the overcap 100 is coupled to the main body 200 by the magnetic force, the coupling strength between the overcap 100 and the main body 200 is maintained at a certain level or more even when the overcap 100 is frequently detached or used for a long time It can be maintained for a long time. In addition, the user can easily separate the overcap 100 from the main body 200 simply by applying a force to the user.

Thereafter, when the pump head 250 is pushed by the user's finger and moves downward, the inner pipe 241 of the pump 240 also moves downward to pump the contents C.

The contents C can be discharged to the outside of the pump head 250 through the inner pipe 241, the discharge passage structure 254 and the nozzle portion 290 by the pressure change due to the pumping.

The magnetic force generated by the

permanent magnets

120 and 257 is transmitted to the pump head 250 including the inner pump head 252 and the outer pump head 258, Lt; / RTI > However, since the nozzle portion 290 fixes the inner pump head portion 252 and the outer pump head portion 258 to each other, the inner pump head portion 252 and the outer pump head portion 258 of the pump head 250 Can be prevented from being abnormally decomposed

The pump head 250 is rigidly mounted by primary engagement by the engagement of the undercut groove portion 256 and the undercut projection portion 242 and secondary engagement by the sliding projection portion 251 and the stop projection portion 271 , It can be prevented in advance from being separated from the pump 240 of the main body 200 abnormally.

In addition, the main body 200 is advantageous in that it can be a high-quality container product made of a rigid, ampule-type design or the like as a triple container structure by the outer container 210, the intermediate container 220 and the inner container 230 .

Although the cosmetic container having the pump according to the embodiment of the present invention has been described above as a specific embodiment, the present invention is not limited thereto, and the present invention is not limited thereto and may be applied to a cosmetic container having the widest range according to the basic idea disclosed in this specification Should be interpreted. Skilled artisans may implement the pattern of features that have not been explicitly described in combination, substitution of the disclosed embodiments, but which, too, do not depart from the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications may be readily made without departing from the spirit and scope of the invention as defined by the appended claims.
