BACKGROUND

1. Technical Field

The invention relates to a cosmetic container capable of adjusting the amount of content dispensed.

2. Description of the Related Art

A container for a liquid or gel type content (such as a cosmetic, shampoo, detergent, etc.) is generally used with a pump, corresponding to a discharging device, coupled to an upper part of the container. When a user presses down on an upper portion of the pump, the change in pressure and the opening of a valve within the pump allows the content to be dispensed through the pump to the outside. A pump such as described above provides the advantage of greater hygiene, as the content is not exposed to the outside and is thus prevented from spoiling.

The conventional pump, however, entails the problem that the amount of content dispensed is not consistent, as the amount varies according to the extent to which the pump is pressed down. That is, a greater downward force applied on the pump would cause the valve, etc., to move a greater distance and result in a larger amount of dispensing, whereas a smaller downward force applied on the pump would cause the valve, etc., to move a shorter distance and result in a smaller amount of dispensing. Thus, with the conventional pump, the user is unable to accurately adjust the amount of content dispensed.

Also known is a container that stores two types of contents separately within a single container and mixes the contents together at the time of use. This form of mixing container is mainly used in cases where a mixture of the two different types of contents provides a synergetic effect but where a premature mixing of the two different contents before the time of use causes the contents to spoil or exhibit a lowered performance after a prolonged period of distribution.

With this type of mixing container also, providing a constant mixing ratio between the two types of contents can maximize the effect of the mixing. Thus, with this type of mixing container also, there is a need for a function of adjusting the amounts of contents dispensed.

SUMMARY OF THE INVENTION

An aspect of the invention, which was conceived to resolve the problems described above, is to provide a cosmetic container capable of adjusting the amount of content dispensed.

Other objectives of the invention will be more clearly understood from the embodiments set forth below.

A shoulder can be coupled to an upper portion of the outer container, the handle can be rotatably coupled to an upper portion of the shoulder, a nozzle can be coupled to an upper portion of the adjustment member, and the nozzle can be connected with the pump to provide a channel for dispensing the content.

The pump can be provided with a pressing flange and a valve flange, the valve flange can be configured to be downwardly pressed by the pressure protrusion, and the valve flange can be configured to be caught on a guide top surface of the adjustment member.

Shoulder detent indentations can be formed in an outer perimeter of the shoulder, an indicator protrusion can be formed on an inner perimeter of the handle and configured to be insertable into the shoulder detent indentations, and the shoulder detent indentations can be formed in a multiple number to indicate the discharging amount of the pump.

The cosmetic container can include an inner container separably coupled within the outer container, where the content can be filled in the inside of the inner container, and an opening of the inner container can be connected to the pump when the inner container is coupled to the outer container.

A deep tube holder can be coupled to the inner container, and the pump can be inserted into the deep tube holder.

A partition wall can be formed within the outer container, and a multiple number of inner containers can be coupled within interior spaces divided by the partition wall.

Two pumps can be coupled to the outer container, and rotating the adjustment member can increase the dispensing amount of one pump while decreasing the dispensing amount of the other pump.

FIG.1is a perspective view of a cosmetic container100according to an embodiment of the invention, andFIG.2is a perspective view of the cosmetic container100inFIG.1with the nozzle140removed.FIG.3is a cross-sectional view of the cosmetic container100inFIG.1across line AA, andFIG.4is a cross-sectional view of an upper part of the cosmetic container100inFIG.3.

Referring toFIGS.1to4, a cosmetic container100based on this embodiment may include two pumps250,270for pumping and discharging two different types of contents and may be configured such that turning a handle160provided at an upper part of the container allows a relative adjustment of the discharging amounts of the pumps250,270. Incidentally,FIG.2illustrates a configuration that allows the two pumps250,270to discharge equal amounts.

A cosmetic container100based on this embodiment may be used with replacements of the inner container110filled with a content. A cosmetic container100based on this embodiment is illustrated using an example that includes two inner containers110, where each inner container110can be filled with a different type of content. When the content filled in an inner container110is used up, the user can remove the existing inner container110and easily couple a new inner container (filled with a content) for use.

A cosmetic container100based on this embodiment may include two inner containers110, a nozzle140, a handle160, a shoulder170, an adjustment member200, an outer container220, a base240, and two pumps250,270. A cosmetic container100based on an embodiment of the invention can further include an overcap (not shown) that covers an upper portion of the nozzle140.

FIG.5is a perspective view of the inner container110, andFIG.6is a cross-sectional view of the inner container110inFIG.5across line CC.

Referring toFIGS.3to6, a cosmetic container100based on this embodiment may include two inner containers110that can be filled with different types of contents. The contents filled in the inner containers110can be separately discharged by the pumps250,270and mixed together subsequently. The two inner containers110can have the same shape and can be arranged symmetrically to each other.

The inner container110may include a container body122that is filled with a content. The container body122may have a semicircular horizontal cross section such that a flat face128is formed on the exterior. The two inner containers110may be arranged such that the faces128are opposite each other. Also, a coupling thread124may be formed at a lower portion of the inner container110.

A label126can be adhered to the face128, where the label126can be a detachably attached film and can indicate the type or amount, etc., of the content filled in the inner container110. The label126can be provided with a downwardly protruding tag127, to allow the user to easily separate the inner container110from the outer container220by pulling on the tag127.

On the inside of the inner container110, there may be provided a deep tube holder114and a deep tube130.

The deep tube holder114may be coupled to the inside through an opening of the inner container110. The deep tube holder114may have a structure similar to that of the housing252of the pump250,270and may have the housing252inserted therein. The deep tube holder114may be provided with an outwardly protruding flange116at the upper end, and the flange116may be caught on the upper end of the inner container110.

The deep tube holder114may be provided with a downwardly protruding connector protrusion118. The deep tube130may be inserted into the connector protrusion118. As the connector protrusion118connects with the pump250,270and the deep tube130, a content that is drawn through the deep tube130can be made to enter the pump250,270.

The deep tube130may be a hollow tube and may correspond to a channel through which the content suctioned by the pump250,270may move. The deep tube130can be arranged such that the lower end is adjacent to the bottom surface of the inner container110.

A cap112can be coupled to the upper opening of the container body122. The cap112may serve to prevent the content from leaking out and prevent any outside substances from leaking in. The cap112can be removed before the coupling to the outer container220.

FIG.7is a bottom view of the nozzle140.

Referring toFIGS.1,4, and7, the nozzle140may be the part that is pressed down by the user and may include discharge holes142,144through which the two types of contents are discharged. The two types of contents can be discharged, without mixing, through the two discharge holes142,144provided in the nozzle140, to be mixed together for use by the user.

In the outer perimeter of the nozzle140, a first discharge hole142and a second discharge hole144, corresponding to channels for discharging the contents to the outside, may be provided adjacently to each other. The first discharge hole142and second discharge hole144may connect with a first channel146and a second channel148provided within the nozzle140. Also, the first channel146and second channel148may connect with a first protrusion150and second protrusion152that protrude downwards. The first protrusion150and second protrusion152may be inserted into the valves264of the pumps250,270by way of press fitting. As a result, the nozzle140and the valves264of the pumps250,270may move down and up together as an integrated body.

When the nozzle140is pressed down, the contents held in the inner containers110may be suctioned through the pumps250,270and subsequently discharged independently through the first and second protrusions150,152, the first and second channels146,148, and the first and second discharge holes142,144. When the external force is removed, the nozzle140may be moved back up to its original position by the elastic restoring forces of the springs266of the pumps250,270.

FIG.8andFIG.9are a perspective view and a cross-sectional view, respectively, of the handle160.

Referring toFIGS.1to4andFIGS.8and9, the handle160may be located at a lower portion of the nozzle140and may be exposed to the exterior, corresponding to the part that is gripped and rotated by the user. When the handle160is rotated, the adjustment member200may be rotated together, and the amounts of contents discharged from the two pumps250,270can be adjusted relatively.

The handle160can be a hollow tube of a particular length and can be structured such that the top and bottom are both open. The handle may have an outer perimeter162that is exposed to the exterior. An overcap, not shown, can be coupled onto the periphery of the outer perimeter162. An inwardly protruding upper curb163can be formed on the upper end of the outer perimeter162. The upper curb163may be the part where the lower end of the nozzle140is caught, whereby the nozzle140may not be separated from the handle160.

A handle detent indentation166may be provided in the inner perimeter of the handle160. Multiple handle detent indentations166can be provided in certain intervals. Adjustment protrusions210formed on the lower end of the adjustment member200may be inserted into the handle detent indentation166, whereby the handle160and the adjustment member200may rotate together as an integrated body. A handle160based on this embodiment can have three handle detent indentations166arranged in intervals of 120 degrees.

On the inner perimeter of the handle160, below the handle detent indentations166, there can be formed an indicator protrusion168. The indicator protrusion168may be caught on the shoulder detent indentations180formed on the outer perimeter of the shoulder170, allowing the user to perceive that the handle160was rotated by a particular angle. A shoulder170based on this embodiment can include three shoulder detent indentations180, where the shoulder detent indentations180can be arranged to correspond to three positions of the handle160(fully rotated in the clockwise direction, fully rotated in the counterclockwise direction, and middle position).

On the inner perimeter of the handle160, below the indicator protrusions168, there may be formed a rotary groove164. A detent protrusion176formed on the inside of an insertion groove174of the shoulder170may be inserted into the rotary groove164, whereby the handle160may be rotatably coupled to an upper portion of the shoulder170.

FIG.10is a perspective view of the shoulder10, andFIG.11is a cross-sectional view of the shoulder10inFIG.10across line BB.

Referring toFIGS.3to4andFIGS.10to11, the shoulder170may be coupled to an upper portion of the outer container220and may rotatably support the handle160coupled to an upper portion the shoulder170. The shoulder170may be shaped as a cap having a shoulder upper surface182and may include a lower periphery element172and an upper periphery element178. Two pump holes184, through which the pumps250,270may be inserted, may be formed in the shoulder upper surface182, and a center protrusion186may be formed in the center of the shoulder upper surface182.

The lower periphery element172may be the part that is inserted onto the periphery of a shoulder coupling element222formed on an upper portion of the outer container220and may have a diameter greater than that of the upper periphery element178. On the inner perimeter of the lower periphery element172, there may be formed a body coupler groove188. Shoulder coupler protrusions224formed on the outer perimeter on an upper portion of the outer container220may be inserted into the body coupler groove188, whereby the shoulder170may be coupled to the upper portion of the outer container220. On the inner perimeter of the lower periphery element172, anti-rotation protrusions190can be formed in a vertical direction. The anti-rotation protrusions190may be inserted into anti-rotation indentations226formed in the outer perimeter of the upper portion of the outer container220, whereby the shoulder170may be coupled to the upper portion of the outer container220in a nonrotatable manner.

An insertion groove174may be formed at the connecting portion between the lower periphery element172and the upper periphery element178. The detent protrusion176may be formed within the circularly shaped insertion groove174. The detent protrusion176may be inserted into the rotary groove164formed in the inner perimeter of the handle160, whereby the handle160may be rotatably coupled to the shoulder170.

The upper periphery element178may be the part that is rotatably coupled with the handle160. On the outer perimeter of the upper periphery element178, there can be formed a multiple number of (e.g., three) shoulder detent indentations180. The indicator protrusion168formed on the handle160can be inserted into the shoulder detent indentations180, allowing the user to perceive that the handle160is at a particular position or was rotated by a particular angle.

The shoulder170may be provided with a shoulder upper surface182formed on an upper portion of the upper periphery element178. The shoulder upper surface182may be a horizontal plate and may have a center protrusion186protruding upward from the center. The center protrusion186can be separably inserted into a coupling protrusion212protruding downward from the inside of the adjustment member200. The pump holes184may each be formed on either side of the center protrusion186in the shoulder upper surface182. The pump holes184may be formed to penetrate through the shoulder upper surface182and may have the same diameter. The pumps250,270may be inserted through the respective pump holes184.

FIG.12andFIG.13are a perspective view and a bottom view, respectively, of the adjustment member200.

Referring toFIGS.2to4andFIGS.12to13, the adjustment member200may be coupled to an upper portion of the handle160to rotate together with the handle160as an integrated body and may serve to adjust the amounts of contents discharged by the two pumps250,270. The adjustment member200may be shaped as a cap having an open bottom, may have two guide holes202formed in the upper surface, and may be provided with a periphery element206having a particular height.

The guide holes202may be formed symmetrically about the center in the upper surface of the adjustment member200and may have arc-like shapes. A pressure protrusion204having a varying length may protrude downward from certain portions of the inner perimeters of the guide holes202. Also, as shown inFIG.13, the pressure protrusion204may not be formed at other portions of the inner perimeters of the guide holes202.

The length of the pressure protrusion204can increase linearly at portions closer to the end of the guide hole202. Thus, inFIG.13, the pressure protrusion204is not formed at all at one end of the guide holes202(where the pump270(marked in dotted lines) is located) but is formed the longest at the other end of the guide holes202(where the pump250(marked in dotted lines) is located).

At the inner perimeters of the guide holes202, the pressure protrusion204at two points b and c that lie on a line a that passes through the center of rotation (i.e., the center of the upper surface) of the adjustment member200can have the same length. Thus, the valve guide262of a pump250,270that moves along the inner perimeter of a guide hole202can be downwardly pressed by the portions of the pressure protrusion204having the same length at the two points (i.e., b and c inFIG.13).

The pressure protrusion204may press down on the valve guides262of the pumps250,270. Therefore, depending on the position of the pumps250,270within the guide holes202, the distances by which the valve guides262are moved down by the pressure protrusion204can be different. For example, inFIG.13, the pump250is located at a portion where the pressure protrusion204is formed the longest, so that its valve guide262would be pressed by the pressure protrusion204and positioned at the lowest height. Conversely, the pump270is located at a portion where the pressure protrusion204is not formed, so that its valve guide262would not be pressed and would be positioned at the greatest height.

Thus, before the pumps250,270are pressed down by the nozzle140, the heights of the valve guides262of the pumps250,270may be adjusted beforehand by the rotation of the adjustment member200(i.e., the rotation of the handle160by the user), so that the amounts of the contents discharged by the two pumps250,270when pressed by the nozzle140may be adjusted. That is, the pump270of which the valve guide262is at the greatest height can discharge the greatest amount of content when pressed down by the nozzle140, and conversely, the pump250of which the valve guide262is at the lowest height can discharge the smallest amount of content when pressed down by the nozzle.

As a valve guide262is moved from one end of the guide hole202where the pressure protrusion204is not formed to the other end where the pressure protrusion204is formed the longest, the amount of downward movement by the valve guide262can be increased linearly. At the same time, the amount of upward movement by the valve guide262of the other pump can also be increased linearly. Thus, when the two pumps250,270are located at the centers of the guide holes202as inFIG.2, the heights of the valve guides262can be the same, whereby the amounts of contents discharged by the two pumps250,270can also be the same.

From the state shown inFIG.13, the positions of the pumps250,270can be reversed by rotating the adjustment member200in a counterclockwise direction, upon which the pump250can discharge the greatest amount of content, and the pump270can discharge the smallest amount of content.

The valve guides262can be positioned at the centers of the two guide holes202simultaneously (as shown inFIG.2), in which case the pumps250,270can both discharge the same amounts of contents.

Thus, with a cosmetic container100based on this embodiment, the user can readily determine the amounts of contents discharged by the pumps250,270by turning the handle160to adjust the positions of the valve guides262of the pumps250,270within the guide holes202.

The adjustment member200may be provided with a periphery element206having a certain height. Also, adjustment protrusions210may protrude outward from the lower end of the periphery element206. The adjustment protrusions210may be inserted into the handle detent indentations166formed in the inner perimeter of the handle160, whereby the handle160and the adjustment member200may rotate together as an integrated body.

In the center of the inner side of the adjustment member200, there may be a coupling protrusion212protruding downward. The coupling protrusion212may have the shape of a hollow cylinder and may receive the center protrusion186of the shoulder170when it is separably inserted therein.

FIG.14andFIG.15are a perspective view and a cross-sectional view, respectively, of the outer container220.

Referring toFIGS.2to3andFIGS.14to15, the outer container220may form the exterior of the cosmetic container100and may receive a multiple number of inner containers110, which may be separably coupled therein. The outer container220may have the shoulder170coupled to an upper portion thereof and the base240coupled to a lower portion thereof.

The outer container220may have the shape of a hollow cylinder with a placement surface228formed at the top and an open bottom. Two container holes230may be formed in the placement surface228. The upper portions of the inner containers110may pass through the container holes230to be positioned protruding above the outer container220, and the pumps250,270may be inserted into the protruding inner containers110. Thus, the container holes230formed in the placement surface228can be positioned on the same plane as the pump holes184formed in the shoulder upper surface182, to be connected with a particular gap in-between in the vertical direction.

From the center of the placement surface228, between the two container holes230, a coupling protrusion231may protrude upward. The coupling protrusion231can be inserted into a center indentation187formed on the inside of the shoulder170, whereby the shoulder170can be coupled to the upper portion of the outer container220.

On the outer perimeter of the upper portion of the outer container220, there may be formed a shoulder coupling element222. The shoulder coupling element222may be divided from the outer perimeter221of the outer container220by a step (no numeral assigned). The shoulder coupler protrusions224may be formed protruding outward from the shoulder coupling element222. Also, the anti-rotation indentations226may be formed in a vertical direction in the shoulder coupling element222. The anti-rotation indentations226may be positioned in-between the shoulder coupler protrusions224.

The shoulder coupler protrusions224may be inserted into the body coupler groove188formed in the inner perimeter of the shoulder170, whereby the shoulder170may be coupled to the upper portion of the outer container220. Also, the anti-rotation protrusions190formed in the inner perimeter of the shoulder170may be inserted into the anti-rotation indentations226, whereby the shoulder170coupled to the upper portion of the outer container220may be prevented from rotating.

On the inside of the outer container220, a partition wall232may be formed that divides the interior space in two. The inner containers110can be separably coupled to the respective interior spaces divided by the partition wall232.

On the outer perimeter of a lower portion of the outer container220, there may be formed a base coupling element234. The base coupling element234may be divided from the outer perimeter221of the outer container220by a step (no numeral assigned). Two base coupling elements234, each having an arced shape, can be arranged opposite each other with a particular gap in-between. Thus, the inner containers110inserted within the outer container220can have their lower ends exposed to the outside, allowing the user to easily grip the inner containers110. Threads236may be formed on the base coupling elements234, and the base240can be fastened to the lower portion of the outer container220by way of the threads236.

The base240may be a cap that covers the lower end of the outer container220and may serve to cover the inner containers110exposed to the outside and prevent the inner containers110from becoming detached.

FIG.16is a cross-sectional view of a pump250,270.

Referring toFIGS.2,3and16, a cosmetic container100based on this embodiment may be provided with two inner containers110and thus may be provided with two pumps250,270correspondingly. The two pumps250,270can have the same structure and can be coupled to the upper portions of the respective inner containers110to independently discharge different contents. The discharging amounts of the pumps250,270can be adjusted, as the upper portions of their valve guides262are pressed by the pressure protrusion204of the adjustment member200.

As the two pumps250,270may have the same composition, the following provides a description for just one pump250.

The pump250may include a housing252. When an inner container110is coupled to the outer container220, the housing252may be inserted into the deep tube holder114coupled to an upper portion of the inner container110. The bottom surface of the housing252can be placed in tight contact with the bottom surface of the deep tube holder114such as to be capable of suctioning the content. Inside the housing252, a disk254, piston256, guide258, valve guide262, and valve264may be positioned such as to be moveable along the up-down direction.

On the outer perimeter on an upper portion of the housing252, an outwardly protruding housing flange253may be formed. The housing flange253may rest on the upper surface of the flange116of the deep tube holder114, whereby the pump250may be positioned on the upper portion of the deep tube holder114.

The disk254positioned inside the housing252may be positioned on the channel (no numeral assigned) through which the content is suctioned and to be opened or closed according to the pressure within the housing252. That is, when the nozzle140is pressed down so that the guide258, valve264, and valve guide262are moved down, the disk254may be closed (the inside of the housing252is at a higher pressure compared to the inner container110). When the external force on the nozzle140is removed so that the guide258, valve264, and valve guide262are moved up by the elastic restoring force of the spring266, the disk254may be opened (the inside of the housing252is at a lower pressure compared to the inner container110).

Since the disk254corresponds to known technology, as disclosed in Korean Registered Patent No. 1975847, the disk254will not be described here in further detail.

Also, since he composition and operation of the piston256, guide258, valve guide262, and valve264located inside the housing252are the same as or similar to those set forth in the prior art noted above, they will not be described here in further detail.

A housing cover260may be coupled to an upper portion of the housing252. Also, a spring266may be provided between the housing cover260and the pressing flange263of the valve guide262. The spring266may cause the valve guide262, valve264, and guide258to move upward when the external force on the nozzle140is removed.

The valve264can be located at the highest position in the pump250, and the first protrusion150of the nozzle140can be inserted into the open upper end of the valve264. Thus, the content suctioned through the pump250can be discharged to the outside through the first channel146connected with the first protrusion150.

On the outer perimeter of the upper end of the valve264, there may be formed a valve flange265that protrudes outward. The valve flange265may be separated by a particular gap from the pressing flange263, and the guide top surface201of the adjustment member200may be inserted in this gap. Thus, as illustrated inFIG.2, the valve flange265can be exposed above the guide top surface201, while the pressing flange263can be positioned below the guide top surface201so as to be pressed downward by the pressure protrusion204.

From the state shown inFIG.2, if the adjustment member200is rotated due to a rotation of the handle160, the valve264may not move down because of the valve flange265caught on the guide top surface201, and only the valve guide262may move down as the pressing flange263is pressed down by the pressure protrusion204. In this way, the downward movement of the valve guide262may cause a gap to be formed in the vertical direction between the valve264and the valve guide262, and the amount dispensed by the pump250when the nozzle140is pressed may be decreased in proportion to this gap. That is, since the valve guide262has been pressed and moved down by the adjustment member200(whereas the piston256has not moved down), the distance from the piston256has been decreased. In this state, when the pressing down on the nozzle140causes the valve guide262to be pressed further down, the valve guide262may press and move the piston256down sooner. As a result, the suction hole259formed in the guide258may be closed by the piston256sooner, and the amount of content suctioned may be decreased.

Although the above describes a cosmetic container100based on this embodiment as having two inner containers110coupled and correspondingly including two pumps250,270, the present invention is not limited by the number of inner containers110. Thus, a cosmetic container based on another embodiment of the invention can have one inner container100coupled or three or more inner containers100coupled.

Although the above describes a cosmetic container100based on this embodiment as having a circular outer container220and correspondingly having inner containers110with semicircular cross sections, the present invention is not limited by the cross-sectional shapes of the outer container and inner containers. Thus, in a cosmetic container based on another embodiment of the invention, the outer container and inner containers can have cross sections of various shapes such as rectangular or elliptical shapes.

While the foregoing provides a description with reference to an embodiment of the invention, it should be appreciated that a person having ordinary skill in the relevant field of art would be able to make various modifications and alterations to the invention without departing from the spirit and scope of the invention set forth in the scope of claims below.
