The first wing 520 is configured to be disposed as closing the air outflow hole 310 at a normal state, and then to be separated from the air outflow hole 310 and to open the air outflow hole 310 by the pressure of the air flowing into through the air movement tube 220 when pressurizing the container body 100 in a state of the container body 100 being upside down. Meanwhile, the second wing 530 is configured to be disposed as closing the air outflow hole 310 at a normal state, and then to be separated from the air outflow hole 310 by the pressure of the air flowing into through the air inflow hole 612 of the finish cap 600 when pressurizing the container body 100 in a state of the container body 100 being upside down and to open the second air movement hole 430.
The finish cap 600, encasing the housing 400 and coupled to the discharge hole 110, includes a cap body 610 and a cover 620.
The cap body 610 has a screw thread formed at the inner circumferential surface thereof for being screw-coupled to the discharge hole 110, wherein a foam-jetting hole 611 is formed at the center portion of the upper end thereof such that the foam generated through the first mixing part 410 and the second fixing part 420 can be jetted.
Meanwhile, at the upper end of the cap body 610 is formed more than one air inflow holes 612 which surround the foam-jetting hole 611. The outside air flowing into through the air inflow hole 612 passes through a first air movement hole 320, and then moves into the interior of the container body 100 through the air movement tube 220.
The cover 620, which is hinge-coupled to one side of the cap body 610 and opens/closes the foam-jetting hole 611, is preferably provided, at the inner side thereof, with a closing protrusion 621 which closes the foam-jetting hole 611 and thereby prevents the contents from being leaked.
Hereafter, with a reference of Figs. 4 and Fig. 5, a foam-jetting process of a foam-jetting tube container according to exemplary embodiments will be described. Figs. 4 and Fig. 5 are views illustrating an operational state of a foam-jetting tube container according to an exemplary embodiment.
First, referring to Fig. 3, a foam-jetting tube container according to an exemplary embodiment, when a user pressurizes a container body 100 while holding the container body 100 in an upside-down position, the contents stored in the container body 100 flow into the first mixing part 410 through the contents outflow hole 210, and the air existing in the container body 100 simultaneously flows into the first mixing part 410 through the air movement tube 220. Due to this, the contents and air are mixed in the first mixing part 410 and are firstly generated into foam.
The air moving through the air movement tube 220 passes through the air outflow hole 310 and further passes through the air movement groove 332 and the communication groove 411, and then flows into the first mixing part 410. The first wing 520 is disposed as closing the air outflow hole 310 at a normal state, and then, is separated from the air outflow hole 310 and opens the air outflow hole 310 to make the air existing in the container body 100 move to the first mixing part 410 by the pressure of the air moving through the air movement tube 220 when the container body 100 is pressurized in a state of being upside down.
Next, the foam firstly generated in the interior of the first mixing part 410 moves to the second mixing part 420 through the communication hole 412. At this time, foam is secondly generated as passing through the foam mesh 421 provided at the inner side of the second mixing part 420, and then is jetted to the outside through the foam-jetting hole 611.
As in the above, if the container body 100 is depressurized in a state of foam-jetting being completed, the inner pressure of the container body 100 is released as illustrated in Fig. 5, and the second wing 520 is separated from the second air movement hole 430 by the pressure of air flowing into through the air inflow hole 612 and then opens the second air movement hole 430. Therefore, the air flowing into through the air inflow hole 612 passes through the second air movement hole 430, passing through the first air movement hole 320, and moves to the air movement tube 220, such that the air can be stored in the interior of the container body 100.
The present invention is composed of an air inflowing structure such that air can flow into without being contacted with contents in a process of flowing into the container body 100. Therefore, it is possible to fundamentally solve the problem wherein air is generated in the interior of the container body 100 by the contact with contents in a process of the air flowing into through an traditional ball valve or a check valve.
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 certain embodiments and are not intended to limit the meanings of the terms or to restrict the scope of 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 claims should be defined by the technical spirit of the description above.
