Description

AUTOMATIC SPUIT TYPE CAP AND AUTOMATIC SPUIT TYPE VESSEL INCLUDING THE SAME

The present invention relates to an automatic spuit type cap and an automatic spuit type vessel including the same.

In general, cosmetics including liquid-phase contents are stored in vessels, and spuit type caps are used to extract the contents from the vessels.

However, in the case of the spuit type cap in the related art, an operation of opening the cap to open the vessel and a suction operation of the cap for extracting the contents are individually carried out, such that convenience for use deteriorates. In addition, in the case of a cap having a typical spuit structure, the amount of contents, which are sucked and extracted, varies depending on a degree to which a user pushes a pressing portion made of rubber, and a result, it is difficult to extract a constant amount of contents each time the user uses the cap.

An object of the present invention is to provide an automatic spuit type cap and an automatic spuit type vessel including the same, in which a suction operation for extracting contents in a vessel main body is automatically carried out based on an operation of opening a cap (e.g., a rotation of the cap) to open the vessel main body.

To achieve the aforementioned object, an exemplary embodiment of the present invention provides an automatic spuit type cap including: an outer cap; an inner cap which is disposed in the outer cap so as to be rotated integrally with the outer cap, and has a first spiral guide slot; a lifting cap which is disposed in the inner cap, and configured to be moved along the first guide slot by a rotation of the inner cap; a fixing cap which is disposed in the lifting cap, engaged with the lifting cap so as to guide upward and downward movements of the lifting cap, and detachably coupled to a vessel main body; a pipe which is mounted on the fixing cap, and has a flow path; and an elastic member which is provided with a space portion that communicates with the flow path of the pipe, and configured such that a volume of the space portion is decreased when the lifting cap is moved downward, and a volume of the space portion is increased when the lifting cap is moved upward.

Another exemplary embodiment of the present invention provides an automatic spuit type vessel including: a vessel main body which has an opening; and an automatic spuit type cap which is configured to selectively open and close the opening of the vessel main body, and suck contents in the vessel main body when the opening is opened.

Here, the automatic spuit type cap may include: an outer cap; an inner cap which is disposed in the outer cap so as to be rotated integrally with the outer cap, and has a first spiral guide slot; a lifting cap which is disposed in the inner cap, and configured to be moved along the first guide slot by a rotation of the inner cap; a fixing cap which is disposed in the lifting cap, engaged with the lifting cap so as to guide upward and downward movements of the lifting cap, and detachably coupled to the opening of the vessel main body; a pipe which is mounted on the fixing cap, extends into the vessel main body, and has a flow path; and an elastic member which is provided with a space portion that communicates with the flow path of the pipe, and configured such that a volume of the space portion is decreased when the lifting cap is moved downward, and a volume of the space portion is increased when the lifting cap is moved upward.

As described above, the automatic spuit type cap and the automatic spuit type vessel having the same according to the exemplary embodiment of the present invention have the following effects.

The automatic spuit type cap has a structure in which the elastic member having the space portion with a predetermined volume is connected to the pipe for sucking contents in the vessel main body. In this case, the automatic spuit type cap is configured such that a volume of the space portion of the elastic member is changed by a rotation of the automatic spuit type cap, and force is applied to the flow path of the pipe in a suction direction in accordance with the change in volume.

Therefore, a suction operation for extracting contents in the vessel main body is automatically carried out in accordance with an operation of opening the cap (e.g., a rotation of the cap) to open the vessel main body, thereby improving convenience for use.

FIG. 1 is a perspective view illustrating an automatic spuit type cap 100 according to an exemplary embodiment of the present invention, FIG. 2 is an exploded perspective view of the automatic spuit type cap 100 illustrated in FIG. 1, and FIGS. 3 and 4 are perspective views illustrating states in which some constituent elements are removed from the automatic spuit type cap 100 illustrated in FIG. 1.

In addition, FIGS. 5 to 7 are cross-sectional views for explaining one operational state of an automatic spuit type vessel 1 according to the exemplary embodiment of the present invention.

Here, FIG. 5 illustrates a state in which the automatic spuit type vessel 1 is closed by the automatic spuit type cap 100. In addition, FIG. 6 illustrates a state in which contents M in the automatic spuit type vessel 1 are sucked into the automatic spuit type cap 100 by a rotation of the automatic spuit type cap 100. In addition, FIG. 7 illustrates a state in which the contents, which have been sucked into the automatic spuit type cap 100, are being discharged to the outside.

The automatic spuit type vessel 1 includes a vessel main body 10 which has an opening 11, and the automatic spuit type cap 100 which is configured to selectively open and close the opening 11 of the vessel main body 10 and suck the contents M in the vessel main body 10 when the opening 11 is opened. Here, the vessel main body 10 is opened by the automatic spuit type cap 100 by rotating the automatic spuit type cap 100. In addition, the respective constituent elements, which constitute the automatic spuit type vessel 1, may be made of resin, glass, or a metallic material which is typically used for a cosmetic vessel or the like.

Referring to FIG. 1, the automatic spuit type cap 100 is configured to be rotated about a central axis C. In the present specification, up and down directions, an upper region, and a lower region may be defined based on a direction of the central axis C (y-axis direction).

Referring to FIG. 2, the automatic spuit type cap 100 includes an outer cap 110, and an inner cap 120 which is disposed in the outer cap 110 so as to be rotated integrally with the outer cap 110 and has a first spiral guide slot 121.

The outer cap 110 defines an external appearance of the automatic spuit type cap 100, and may have an approximately hollow cylindrical shape. A user may separate the automatic spuit type cap 110 from the vessel main body 10 by manipulating (rotating) the outer cap 110. In addition, a deco cap 180 for presenting an aesthetically attractive external appearance may be mounted on the outer cap 110.

In addition, the inner cap 120 is formed to have a smaller diameter than the outer cap, and may have an approximately hollow cylindrical shape. The first guide slot 121 is provided in the inner cap 120 in a circumferential direction based on the central axis C, and particularly, the first guide slot 121 is provided in a spiral manner in the central axis direction C.

Here, a plurality of first guide slots 121 may be provided in the inner cap 120, and for example, two first guide slots 121 may be provided in the inner cap 120 in the circumferential direction at a predetermined interval.

In addition, the inner cap 120 is disposed to be engaged with a partial region of the outer cap 110 so as to be rotated integrally with the outer cap 110. For example, a first engagement structure 122, which has concave-convex portions such as a gear or a latch, is provided on an outer circumferential surface of the inner cap 120. In addition, a second engagement structure, which is engaged with the first engagement structure 122 of the inner cap 120, is provided on the outer cap 110.

In addition, the outer cap 110 and the inner cap 120 may be configured to be integrally rotated only when the outer cap 110 is rotated in one direction (clockwise or counterclockwise).

In addition, the automatic spuit type cap 100 includes a lifting cap 130 which is disposed in the inner cap 120 and configured to move along the first guide slot 121 by the rotation of the inner cap 120, and a fixing cap 140 which is disposed in the lifting cap 130, engaged with the lifting cap 130 so as to guide the upward and downward movement of the lifting cap 130, and detachably coupled to the vessel main body 10.

Referring to FIGS. 3 and 4, a lifting protrusion 132, which is inserted into the first guide slot 121, may be provided on the lifting cap 130. The lifting cap 130 and the inner cap 120 are constructed to be engaged with each other as the lifting protrusion 132 is disposed in the first guide slot 121. In this case, the lifting cap 130 is configured to be moved upward and downward along the first guide slot 121 by the rotation of the inner cap 120. For example, the lifting cap 130 is configured to be moved upward along the first guide slot 121 by a rotation of the inner cap 120 in a first direction, and the lifting cap 130 is configured to be moved downward along the first guide slot 121 by a rotation of the inner cap 120 in a second direction. In this case, the first direction and the second direction are opposite to each other, and for example, when the first direction is a clockwise direction, the second direction may be a counterclockwise direction.

Here, the first guide slot 121 includes a first region 121a positioned at a lower side and a second region 121b positioned at an upper side, in the spiral direction based on the central axis C.

Referring to FIG. 5, in a state in which the automatic spuit type cap 100 is mounted at the opening 11 of the vessel main body 10 (a closed state), the lifting protrusion 132 of the lifting cap 130 is positioned in the first region 121a of the first guide slot 121.

Referring to FIGS. 3 and 6, when the automatic spuit type cap 100 is separated from the opening 11 of the vessel main body 10 by the rotation of the outer cap 110, the lifting protrusion 132 of the lifting cap 130 moves along the first guide slot 121, such that the lifting cap 130 is moved upward relative to the inner cap 110. When the lifting cap 130 is moved upward relative to the inner cap 110, the lifting protrusion 132 is positioned in the second region 121b of the first guide slot 121.

In addition, referring to FIGS. 3 and 4, a second guide slot 131, which is opened in an up and down direction, is provided in the lifting cap 130, and a guide protrusion 141, which is inserted into the second guide slot 131, is provided on the fixing cap 140. The second guide slot 131 is provided to be substantially parallel to the central axis C. With the engagement between the second guide slot 131 and the guide protrusion 141, rotational force of the outer cap 110 may be sequentially transmitted to the fixing cap 140. Meanwhile, when the outer cap 110 is rotated, the inner cap 120 and the fixing cap 140 are not moved upward, but only the lifting cap 130 is moved upward relative to the inner cap 120 and the fixing cap 140.

In addition, when the lifting cap 130 is completely moved upward relative to the inner cap 120, the lifting protrusion 132 is positioned in the second region 121b of the first guide slot 121, and the lifting protrusion 132 is positioned above the guide protrusion 141. On the contrary, when the lifting cap 130 is completely moved downward, the lifting protrusion 132 is positioned in the first region 121a of the first guide slot 121, and the lifting protrusion 132 is positioned below the guide protrusion 141.

In addition, the automatic spuit type cap 100 includes a pipe 150 which is mounted on the fixing cap 140 and has a flow path 151. In addition, the automatic spuit type cap 100 includes an elastic member 160 which has a space portion 161 that communicates with the flow path 151 of the pipe 150. The elastic member 160 may be made of, for example, silicone.

The elastic member 160 is configured such that a volume of the space portion 161 is decreased when the lifting cap 130 is moved downward, and a volume of the space portion 161 is increased when the lifting cap 130 is moved upward. With the aforementioned structure, referring to FIG. 6, when a volume of the space portion 161 of the elastic member 160 is increased, suction force is applied to the flow path of the pipe 150 toward the space portion 161 of the elastic member 160.

In addition, the automatic spuit type cap 100 may further include a cover cap 170 which is connected with the lifting cap 130 and configured to be in contact with the elastic member 160. The cover cap 170 may be configured to be positioned above the lifting cap 130. In addition, the description that the cover cap 170 is connected with the lifting cap 130 means that the cover cap 170 is connected with the lifting cap 130 so that the cover cap 210 may be moved upward as the lifting cap 130 is moved upward. In addition, the cover cap 170 and the lifting cap 130 may be connected to be engaged with each other in a partial region in order to prevent the cover cap 170 from being withdrawn (separated) from the lifting cap 130.

Here, the elastic member 160 is configured such that the space portion 161 is positioned in a space between the fixing cap 140 and the cover cap 170.

Referring to FIG. 5, in a state in which the automatic spuit type cap 100 is mounted at the opening 11 of the vessel main body 10 (a closed state), the lifting protrusion 132 of the lifting cap 130 is positioned in the first region 121a of the first guide slot 121. In addition, the cover cap 170, which is engaged with the lifting cap 130, is positioned above the lifting cap 130 and becomes close to the fixing cap 140. Therefore, the space portion 161 of the elastic member 160, which is positioned between the fixing cap 140 and the cover cap 170, is kept relatively compressed.

Referring to FIG. 6, when the automatic spuit type cap 100 is separated from the opening 11 of the vessel main body 10 by the rotation of the outer cap 110, the lifting protrusion 132 of the lifting cap 130 moves along the first guide slot 121, such that the lifting cap 130 is moved upward relative to the inner cap 110.

Here, the compressed state of the space portion 161 of the elastic member 160 is relatively released by the upward movement of the lifting cap 130. In addition, as a volume of the space portion 161 of the elastic member 160 is increased, suction force is applied to the flow path 151 of the pipe 150 toward the space portion 161 of the elastic member 160. Therefore, the contents M in the vessel main body 10 are sucked into the flow path 151 of the pipe 150.

Specifically, when the fixing cap 140 is separated from the vessel main body 10 by the rotation of the outer cap 110, the lifting cap 130 is moved upward, and a volume of the space portion 161 of the elastic member 160 is increased. In addition, as a volume of the space portion 161 is increased, the expansion of the elastic member 160 may assist the upward movement of the lifting cap and the upward movement of the cover cap 170. In addition, the cover cap 170 may be configured such that a partial region of the cover cap 170 is exposed to the outside of the outer cap 110 when the cover cap 210 is moved upward.

Meanwhile, referring to FIGS. 3 and 7, when the cover cap 170 is pressed toward the fixing cap 140, a volume of the space portion 161 of the elastic member 160 is decreased, and the lifting cap 130 is moved downward along the first guide slot 210. In addition, when a volume of the space portion 161 of the elastic member 160 is decreased (the elastic member is compressed), the contents accommodated in the flow path 151 of the pipe 150 are discharged to the outside of the pipe 150. As described above, the cover cap 170 functions as a button for discharging the contents, which have been sucked into the automatic spuit type cap 100, to the outside. The user may discharge the contents in the pipe 150 to the outside of the pipe 150 by pressing the cover cap 170, which is exposed to the outside of the outer cap 110, toward the pipe 150.

Meanwhile, the fixing cap 140 may be separably thread-coupled to the opening 11 of the vessel main body 10. To this end, a threaded portion 142 may be provided on an inner circumferential surface of the fixing cap 140. In addition, a thread-coupling portion 12, which is thread-coupled to the threaded portion 142, may be provided on an outer circumferential surface of the opening 11 of the vessel main body 10.

It should be understood that the aforementioned exemplary embodiments of the present invention are described for illustration, and may be variously modified, changed, and added by those skilled in the art without departing from the spirit and scope of the present invention, and the modification, change, and addition belong to the appended claims.

A suction operation for extracting contents in the vessel main body is automatically carried out in accordance with an operation of opening the cap (e.g., a rotation of the cap) to open the vessel main body, thereby improving convenience for use.
