DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members.
Fig.1 is an exploded cross-sectional view illustrating a configuration of a foam jetting tube container according to an exemplary embodiment of the present invention, and Fig. 2 is a cross-sectional view illustrating a configuration of a foam jetting tube container according to an exemplary embodiment of the present invention;
Referring to Figs.1 and 2, a foam jetting tube container according to an exemplary embodiment of the present invention includes a container body 100, a housing 200, a foam mesh 300, and an over cap 400.
The container body 100, where liquid-type contents are stored, comprises a discharge hole at an upper portion thereof such that the contents can be discharged by a user's pressurizing.
The container body 100 can be composed of a tube container or a blow container which is able to be modified by a user's pressurizing and discharges the contents stored in the container body.
The housing is combined to the discharge hole 110 at an upper portion of the container body 100 and closes an upper end of the discharge hole 110, the housing in the present invention is characterized in that at the center portion of the housing 200 is equipped a mixing part 210 where the contents and the air stored in the container body 100 are mixed and foam is primarily formed.
The mixing part 210, so as to make the contents and the air mixed, is equipped with a content inflow hole 211 at a lower end thereof, which the contents stored in the container body 100 flows in, and at a side surface thereof is equipped with an air inflow hole 212 where the air stored in the interior of the container body 100 enters, and at a lower end of the mixing part 210 is equipped a content moving tube 230 such that the contents stored in the container body 100 moves to direction of the mixing part 210 and flows into the mixing part 210 through the content inflow hole 211.
Meanwhile, the housing 200 is featured to include an air inlet 220 thereof such that outside air enters the container body 100, wherein at the air inlet 220 is installed a valve member 221 which regulates entering of outside air according to whether the container body 100 is pressurized or not.
The valve member 221 ascends or descends inside the air inlet 220 according to the operation of pressurizing the container body 100 or releasing the pressure, thereby closing an upper portion or a lower portion of the air inlet 220. When pressure of the container body 100 is released and thereby the valve member 221 moves from an upper portion to a lower portion of the air inlet 220, air enters an interior of the container body 100 through a space separated between an inner wall of the air inlet 220 and the valve member 221.
The foam mesh 300 is combined to an upper portion of the mixing part 210 and generates foam, wherein the content and air stored in the container body 100, in a process of moving upward, go through the mixing part 210, primarily forming foam, and then pass through the foam mesh, secondly forming foam. When enough foam is formed, the foam is discharged to the outside through the foam getting hole 411.
The over cap 400 encases the housing 200 and the foam mesh and is combined to the discharge hole 110, comprising a cap body 410 which has a screw thread at an inner circumferential surface and is combined in screw coupling to the discharge hole 110, comprising a foam jetting hole 411 at the center of a cap body 410 such that discharging foam is possible, and a cover 420 which is combined in a hinge combination with one side of the cap body 410 and opens/closes the foam jetting hole 411. It is preferable that at an inner side of the cover 420 is equipped a closing protrusion 421 which opens/closes the foam jetting hole 411 and thereby prevents contents from being leaked.
Meanwhile, at an upper end of the housing 200 is combined a fixing cap 500 which supports the foam mesh 300, wherein a hollow 510 is formed at the fixing cap 500 such that foam, formed while going through the foam mesh 300, can move.
Hereinafter, the foam jetting process of a foam jetting tube container according to an exemplary embodiment of the present invention will be described with reference to Fig. 3 and 4. Fig.3 and 4 are constitutional views illustrating an operational state of a foam jetting tube container according to an exemplary embodiment of the present invention.
First, referring to Fig. 3, a foam jetting tube container according to an exemplary embodiment of the present invention, when a user pressurizes a container body 100 with the container body 100 in an upright position, the contents stored in the container body 100 moves to an upper portion thereof through a content moving tube 230 and flows into a mixing part 210 through a content inflow hole 211, and at the same time, the air contained in an upper portion of the container body 100 flows into the mixing part 210 through an air inflow hole 212, such that the contents and the air are mixed in the mixing part 210, primarily forming foam, and then secondly forms foam as going through a foam mesh 300 positioned at an upper portion of the mixing part 210, then being discharged to the outside through a foam jetting hole 411. At this time, a valve member 221 moves to an upper portion of the air inlet 220 by internal pressure of the container body 100, thereby closing the air inlet 220.
As above, when pressurization of the container body 100 is released in a state of foam jetting completed, the internal pressure of the container body 100 is released, and thereby, shown in Fig.5, the valve member 221 which moved up to an upper portion of the container 220 comes to descend. During this process when the valve member is descending, air from the outside enters into the interior of the container body 100 through a separated space formed between an inner wall of the air inlet 220 and the valve member 221, and thereby the air is stored in an inner upper space of the container body 100, and when the user pressurizes the container body 100 again, the air contained in the inner upper space of the container body 100 flows in through the air inflow hole 212 and mixes with contents in the mixing part 210, then jetting foam.
Meanwhile, shown in Fig. 4, when the container body 100 is pressurized in a state of the container body 100 being upside down, the air inflow hole 212 functions as a passage where the contents stored in the container body 100 moves whereas a content moving tube 230 functions as a passage where air stored in the container body 100 moves. Therefore, contents flow in through the air inflow hole 212 while air flows in through the content moving hole 230, and then contents and air are mixed in the mixing part 210, such that it is possible for foam to be jetted easily even in a state of the container body 100 being upside down.
The process that contents and air are mixed through the mixing part 210 and a foam mesh and then foam is jetted is the same as the above; therefore, detailed descriptions are omitted.
As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe the present invention and are not intended to limit the meanings of the terms or to restrict the scope of the present invention as disclosed in the accompanying claims. Therefore, those skilled in the art will appreciate that various modifications and other equivalent embodiments are possible from the above embodiments. Therefore, the scope of the present invention should be defined by the technical spirit of the accompanying claims.
