FOAM GENERATOR FOR INVERTED COMPRESSION RECEPTACLES

Abstract

The foam generator for inverted compression receptacles according to the present invention is configured such that liquid contents pumped by an internal pressure as a result of directly compressing an inverted compression receptacle (100), having the liquid contents stored therein, are mixed with air in a gas-liquid mixing chamber (S) and, at the same time, directly discharged in the form of foam. That is, direct compression of the inverted compression receptacle (100) allows the liquid contents to be instantly discharged in the form of foam, thereby further improving product responsiveness. In particular, the present invention is capable of further improving the convenience of use thereof, since the contents can be discharged in the form of foam by directly compressing the inverted compression receptacle (100) merely with one hand. In addition, the foam generator for inverted compression receptacles according to the present invention allows the discharged foam to be applied to or cleanse skin by means of a message member (900) having massage bristles (930) attached thereto. In particular, the present invention is capable of producing a messaging effect while allowing the discharged foam (contents) to be directly and evenly applied to the skin by means of the message member (900) even without the use of palms.

BEST MODE

[0042] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Briefly describing the accompanying drawings, FIGS. 2 to 6 show the structure of a foam generator for inverted compression receptacles according to the present invention, and FIGS. 7 to 9 show the state in which the foam generator for inverted compression receptacles according to the present invention is used.

Description of Structure of Foam Generator for Inverted Compression Receptacles according to the Present Invention

[0043] The foam generator for inverted compression receptacles according to the present invention is mounted to a neck of an inverted compression receptacle having contents stored therein such that liquid contents are discharged out of the inverted compression receptacle in the form of foam while the liquid contents are mixed with air using the pressure generated in the inverted compression receptacle when the inverted compression receptacle is directly compressed. As shown in FIGS. 2 and 3, the foam generator for inverted compression receptacles includes an inverted compression receptacle 100 having liquid contents stored therein, the inverted compression receptacle 100 being configured to be restored to the original state thereof due to the elastic force thereof, a cap main body 200 coupled to a neck 110 of the inverted compression receptacle 100, a content discharge guide 300 received and disposed in the cap main body 200 for guiding the discharge of the liquid contents and air when the inverted compression receptacle 100 is compressed, a valve housing 400 coupled to the upper part of the content discharge guide 300, a content check valve 430 for controlling the discharge of the liquid contents being mounted in the valve housing 400, an air check valve unit 600 for controlling the suction and discharge of air according to the compression and restoration operation of the inverted compression receptacle 100, a filtration member 700 received and disposed in the cap main body 200 for homogenizing foam formed as the result of the liquid contents being mixed with air, an upward and downward movement cap 800 assembled to the lower part of the cap main body 200 so as to be movable upward and downward for ejecting the foam to the outside, and a massage member 900 mounted to the lower part of the upward and downward movement cap 800. The detailed structures of the respective components constituting the foam generator for inverted compression receptacles according to the present invention are as follows.

[0044] First, the inverted compression receptacle 100 has liquid contents stored therein. As shown in FIG. 2, the inverted compression receptacle 100 is made of soft synthetic resin, which can be compressed by a user using his/her hand and which can be restored to the original state thereof when the compression force is removed. Screw threads are formed in the outer wall of the neck 110 of the inverted compression receptacle 100, which is used in the inverted state. The neck 110 is formed at the lower part of the inverted compression receptacle 100 based on the state in which the inverted compression receptacle 100 is used.

[0045] The cap main body 200 is made of hard synthetic resin. As shown in FIGS. 3 to 5, the cap main body 200 includes a large cap part 210 fastened to the neck 110 of the inverted compression receptacle 100 in a screw coupling manner and a foam discharge part 240 protruding from the lower part of the large cap part 210 in the shape of a pipe having a reduced diameter while a step 230 is formed at the upper end thereof, the lower part of the foam discharge part 240 being open. In addition, an air hole 250 for allowing external air to be introduced therethrough is formed in the step 230 of the cap main body 200. The air hole 250 is configured to allow the external air to be introduced into the inverted compression receptacle 100 therethrough when the inverted compression receptacle 100 is elastically restored to the original state thereof. In addition, an upward and downward movement guide wall 220, which is formed in the shape of a cylinder, is integrally formed at the outside of the large cap part 210. The upward and downward movement guide wall 220 is configured to guide the upward and downward movement of the upward and downward movement cap 800. Support shafts 260 are formed inside the upward and downward movement guide wall 220 in a protruding manner such that the support shafts 260 are opposite each other.

[0046] The content discharge guide 300 is also made of hard synthetic resin. As shown in FIGS. 3 to 5, an edge 310 of the content discharge guide 300 is fitted, received, and disposed in the lower end of the large cap part 210 of the cap main body 200 so as to be spaced apart from the upper part of the step 230 of the cap main body 200 by a predetermined distance such that a space is defined therebetween. The content discharge guide 300 includes a discharge guide part 320 having a liquid discharge port 330 formed in the center thereof so as to be recessed concavely and a cylindrical discharge channel 340 protruding from the upper part of the center of the discharge guide part 320 for guiding the discharge of the liquid contents. In addition, the discharge guide part 320 is provided at the outside thereof with an air discharge port 350, through which the air in the inverted compression receptacle 100 can move to the lower side of the discharge guide part 320 when the inverted compression receptacle 100 is compressed, and with an air introduction port 360, through which external air that has been introduced through the air hole 250 can be introduced into the inverted compression receptacle 100 when the inverted compression receptacle 100 is restored to the original state thereof. In this embodiment of the present invention, six air introduction ports 360 are formed in the outside of the discharge guide part 320 such that the inverted compression receptacle 100 can be instantly restored to the original state thereof, and two air discharge ports 350 are formed so as to be opposite each other, i.e. to be offset at an angle of 180 degrees, such that air can rapidly move to an air and liquid mixing chamber S, a description of which will follow, when the inverted compression receptacle 100 is compressed. In addition, the liquid discharge port 330 of the discharge guide part 320 is formed so as to branch into a plurality of liquid discharge ports at the center of the discharge guide part 320 in the radial direction thereof such that the liquid contents discharged upward through the discharge tube 130 are distributed and smoothly mixed with air in the air and liquid mixing chamber S (in this embodiment of the present invention, the liquid discharge port 330 branches into two liquid discharge ports that are opposite each other, i.e. are offset at an angle of 180 degrees).

[0047] As shown in FIGS. 3 to 6, the valve housing 400 includes a cylindrical coupling part 440 fitted and coupled into the upper part of the content discharge guide 300 so as to cover the upper part of the content discharge guide 300 such that an air compartment 410, which communicates with the air discharge ports 350 and the air introduction ports 360, is defined in the cylindrical coupling part 440. The cylindrical coupling part 440 is provided in the central region thereof with a content suction port 420. The cylindrical coupling part 440 is coaxially fitted and coupled into the discharge channel 340 defined in the content discharge guide 300. The content check valve 430, which selectively opens and closes the content suction port 420 depending on whether the inverted compression receptacle 100 is compressed, is received and disposed in the coupling part 440 of the valve housing 400. The content check valve 430 includes a valve body 431 disposed in the coupling part 440 of the valve housing 400 so as to be slidable vertically for opening and closing the content suction port 420, the upper end of the valve body 431 being formed in a conical shape, and an elastic member 432 (a coil spring in the embodiment of the present invention) for elastically supporting the valve body 431 upward in the coupling part 440. When the inverted compression receptacle 100 is compressed, therefore, the pressure in the inverted compression receptacle 100 pushes the valve body 431 downward against the elastic supporting force of the elastic member 432. As a result, the liquid contents move to the discharge guide part 320 of the content discharge guide 300. In addition, a tube fitting port 450 protrudes from the upper surface of the valve housing 400 so as to communicate with the air compartment 410. An air tube 500 is fitted and coupled into the tube fitting port 450. That is, the lower end of the air tube 500 is fitted and coupled into the tube fitting port 450, and the upper end of the air tube 500 extends toward the upper part of the inverted compression receptacle 100. Consequently, the upper space in the inverted compression receptacle 100, in which air remains, and the air compartment 410 communicate with each other through the air tube 500.

[0048] The air check valve unit 600 is made of an elastic rubber material (silicone or NBR). As shown in FIGS. 3 to 5, the air check valve unit 600 includes a ring-shaped partition wall 610, having an upper end disposed in tight contact with the lower surface of the bottom of the content discharge guide 300 and a lower end disposed in tight contact with the upper part of the step 230 of the cap main body 200, for defining the air and liquid mixing chamber S in the foam discharge part 240, a first check valve part 620 disposed inside the partition wall 610 so as to extend upward toward the central part thereof, an end of the first check valve part 620 being disposed in elastically tight contact with the discharge guide part 320 of the content discharge guide 300, the first check valve part 620 being configured to allow the air discharged from the inverted compression receptacle 100 through the air discharge ports 350 to move to the air and liquid mixing chamber S when the inverted compression receptacle 100 is compressed, and a second check valve part 630 disposed outside the partition wall 610 so as to extend downward toward the outside, an end of the second check valve part 630 being disposed in elastically tight contact with the outside of the step 230 of the cap main body 200, the second check valve part 630 being configured to close the air hole 250 when the inverted compression receptacle 100 is compressed and to open the air hole 250 when the inverted compression receptacle 100 is restored to the original state thereof such that air can be introduced through the air hole 250.

[0049] As shown in FIGS. 3 to 5, the filtration member 700 includes a cylindrical body 710 fitted, received, and disposed in the foam discharge part 240 (the air and liquid mixing chamber S) of the cap main body 200, the upper and lower parts of the cylindrical body 710 being open, and mesh-shaped filtration nets 720 and 730 provided to cover the upper and lower surfaces of the body 710. Consequently, the filtration member 700 guides the downward discharge of foam formed as the result of the liquid contents being mixed with air in the air and liquid mixing chamber S while homogenizing the foam.

[0050] The upward and downward movement cap 800 is configured to guide the discharge of the foam in the foam generator for inverted compression receptacles according to the present invention to the outside and to lock the foam generator for inverted compression receptacles according to the present invention. As shown in FIGS. 3 to 5, the upward and downward movement cap 800 includes a cylindrical wall surface 810 having an upper end received in and coupled to the upward and downward movement guide wall 220 of the cap main body 200 so as to be movable upward and downward and a lower surface 820 configured to cover the lower part of the cap main body 200, the lower surface 820 being provided with a plurality of foam distribution holes 830, through which the foam that has passed through the filtration member 700 is discharged to the outside in a distributed manner. In addition, the upward and downward movement cap 800 is provided at the center of the lower surface 820 thereof with a cylindrical blocking wall 840 for selectively opening and closing the foam discharge part 240 according to the upward and downward manipulation thereof so as to allow or prevent the communication between the foam discharge part 240 and the foam distribution holes 830.

[0051] The upward and downward movement of the upward and downward movement cap 800 is achieved by rotating the upward and downward movement cap 800 in the forward direction and the reverse direction. That is, the upward and downward movement cap 800 is provided at the outside of the wall surface 810 thereof with spiral grooves 850 inclined upward from the lower part thereof for receiving the support shafts 260. The spiral grooves 850 are formed so as to be opposite each other in a predetermined region (a 90-degree region in the present invention). Consequently, the upward and downward movement cap 800 is moved downward or upward to the regular positions thereof by rotating the upward and downward movement cap 800 in the forward direction or the reverse direction. When the upward and downward movement cap 800 is moved maximally downward as the result of the rotation of the upward and downward movement cap 800 in the forward direction (in the direction indicated by the arrow A in FIG. 5), therefore, the cylindrical blocking wall 840 becomes spaced apart from the upper part of the foam discharge part 240. As a result, the foam discharge part 240 communicates with the foam distribution holes 830, whereby the foam can be discharged. On the other hand, when the upward and downward movement cap 800 is moved maximally upward as the result of the rotation of the upward and downward movement cap 800 in the reverse direction (in the direction indicated by the arrow B in FIG. 5), the cylindrical blocking wall 840 completely closes the lower part of the foam discharge part 240. As a result, the foam is prevented from being discharged (see FIG. 9).

[0052] Meanwhile, as shown in FIGS. 3 to 5, the massage member 900 includes a base 910 fitted and mounted in the lower part of the upward and downward movement cap 800 so as to cover the lower part of the upward and downward movement cap 800, the base 910 being provided therein with a plurality of communication ports 920, which communicate with the respective foam distribution holes 830, and massage bristles 930 implanted over the entire lower surface of the base 910. The massage bristles 930 are configured to uniformly apply the foam discharged through the communication ports 920 to the skin of a user in the state of being in elastic contact with the skin of the user.

Description of Operation and Effects of Foam Generator for Inverted Compression Receptacles According to the Present Invention

[0053] Next, the operation and effects of the foam generator for inverted compression receptacles according to the present invention will be described with reference to FIGS. 2 and 7 to 9.

[0054] First, as shown in FIG. 2, when the foam generator for inverted compression receptacles according to the present invention is in an initial state, the inverted compression receptacle 100 having the liquid contents and the air stored therein is maintained in the original state thereof, and the content check valve 430 keeps the content suction port 420 closed. In addition, the first check valve part 620 of the air check valve unit 600 is disposed in tight contact with the discharge guide part 320 of the content discharge guide 300 due to the elastic restoration force thereof, and the second check valve part 630 of the air check valve unit 600 is also disposed in tight contact with the outside of the step 230 of the cap main body 200 so as to keep the air hole 250 closed using the elastic restoration force thereof.

[0055] When a user presses the inverted compression receptacle 100 in order to compress the inverted compression receptacle 100 (see the direction indicated by the arrow in FIG. 7) in the state in which the upward and downward movement cap 800 has been moved downward, as shown in FIG. 7, pressure is generated in the inverted compression receptacle 100. As a result, the air and the liquid contents in the inverted compression receptacle 100 are compressed.

[0056] Consequently, some of the liquid contents stored in the inverted compression receptacle 100 move to the air and liquid mixing chamber S through the liquid discharge ports 330 as the result of opening of the content check valve 430 (see the direction indicated by the solid arrow in FIG. 7). In addition, some of the air in the inverted compression receptacle 100 is compressed, is introduced into the air compartment 410 of the valve housing 400 through the air tube 500, closes the second check valve part 630, opens the first check valve part 620, and then moves to the air and liquid mixing chamber S (see the direction indicated by the dashed arrow in FIG. 7).

[0057] In the air and liquid mixing chamber S, the compressed air and the liquid contents are mixed with each other to form foam. Since the liquid contents are discharged while being distributed through the liquid discharge ports 330, the liquid contents can be more smoothly mixed with the air to instantly form foam. The foam is homogenized while passing through the filtration member 700. The homogenized foam is discharged to the outside via the foam distribution holes 830 in the upward and downward movement cap 800 and the communication ports 920 in the massage member 900.

[0058] When the artificial force applied to the inverted compression receptacle 100 is removed, as shown in FIG. 8, the inverted compression receptacle 100 is restored to the original state thereof due to the elastic restoration force thereof, whereby negative pressure is generated in the inverted compression receptacle 100. That is, when negative pressure is generated in the inverted compression receptacle 100 as the result of restoration of the distorted compression receptacle 100 to the original state thereof, the second check valve part 630 of the air check valve unit 600 is instantaneously opened. As a result, external air is introduced into the air compartment 410 of the valve housing 400 through the air hole 250 and the air introduction ports 360. Subsequently, the air that has been introduced into the air compartment 410 is introduced into the inverted compression receptacle 100 through the air tube 500. That is, a volume of external air equal to that of the liquid contents that have been discharged from the inverted compression receptacle 100 is introduced into the inverted compression receptacle 100 through the air hole 250 and the air introduction ports 360, whereby the inverted compression receptacle 100 is maintained in the initial state thereof. During the restoration of the inverted compression receptacle 100, the first check valve part 620 of the air check valve unit 600 comes into tight contact with the discharge guide part 320 in order to close the air discharge ports 350.

[0059] This series of processes may be repeated in order to eject and use the liquid contents stored in the inverted compression receptacle 100 in the form of foam. That is, in the foam generator for inverted compression receptacles according to the present invention, the inverted compression receptacle 100 having the contents stored therein is directly compressed. As a result, the liquid contents are mixed with air due to the pressure in the inverted compression receptacle 100, and the mixture is directly discharged in the form of foam. In addition, even when the user directly compresses the inverted compression receptacle 100 using one hand, the contents are discharged to the outside in the form of foam, thereby improving user convenience. Furthermore, the user can uniformly apply the foam discharged to the outside to his/her skin or can cleanse his/her skin using the massage member 900 without using his/her hands. In particular, the user can uniformly apply the foam to his/her skin while pushing the massage bristles 930 of the massage member 900 onto his/her skin in the manner of massaging the skin of the user.

[0060] Meanwhile, when the upward and downward movement cap 800 is rotated by 90 degrees in the reverse direction (in the direction indicted by the arrow B in FIG. 9), as shown in FIG. 9, the upward and downward movement cap 800 is moved upward, whereby the cylindrical blocking wall 840 is received in the foam discharge part 240 while coming into tight contact with the foam discharge part 240 in order to close the foam discharge part 240. {Since the support shafts 260 are received in and coupled to the respective spiral grooves 850, as previously described, the upward and downward movement cap 800 is moved upward and downward only to the regular positions thereof by rotating the upward and downward movement cap 800 in the forward direction and the reverse direction.} In the state in which the upward and downward movement cap 800 has been moved upward to close the foam discharge part 240, as described above, foam (contents and air) can be completely prevented from being discharged even when the inverted compression receptacle 100 is pressed such that the inverted compression receptacle 100 is compressed, whereby the inverted compression receptacle 100 remains locked. That is, the discharge of foam is guided and the inverted compression receptacle 100 is locked through the upward and downward movement cap 800 fastened to the inverted compression receptacle 100 in a rotation and upward and downward movement manner, whereby it is possible to more stably use the product and to prevent the leakage of liquid from the product during the distribution of the product.

INDUSTRIAL APPLICABILITY

[0061] The present invention is widely applicable to the field of a foam generator for inverted compression receptacles that is capable of mixing contents with air and discharging the mixture in the form of foam when an inverted compression receptacle is directly compressed.
