KR100786962B1 - Drip-less carbonated beverage container flow control element with suction spout - Google Patents

Abstract

The invention related to a "flow control element" with suction spout for carbonated beverage cans. The fluid remains under pressure while access is possible when suction is applied to the spout. The spout is attached to a housing enclosure that holds a spring, a centrally perforated membrane, a valve stem and a valve. This housing enclosure extends into the inside of the container, which extended part functions as a guide for the valve stem and that incorporates the valve seat. The valve stem is attached to the perforated membrane on one side and to the valve on the other side. When suction is applied the membrane moves the valve and opens a flow path, thereby allowing fluid to flow through the valve stem and the perforated membrane to the mouth. When the suction stops, a spring closes the valve against the gas pressure in the can or container.

Field of invention

The present invention relates to a fully enclosed carbonated beverage can, bottle or closed beverage cup, which is used to prevent the outflow of fluid therein when the fluid is removed from the can, beverage cup or hand held container while in motion. US classification 220/706; 220/85; 222/214; 220/713; 220/714 and the like (International Patent Classification A47G 19/22; BD65d 1/00; BD65D 25/48, etc.).

Purpose of the Invention

Carbonated beverages are filled in aluminum cans, bottles or other containers for consumption. As soon as the can or bottle is opened, the fluid inside begins to deteriorate and shortly afterwards the steam depletes. If it is in a bottle, pour it into a cup for immediate drinking and the rest is closed with a screw cap for later use to maintain pressure inside the bottle. However, aluminum cans are generally opened by removing a portion of the upper closure and cannot be closed afterwards. This means that you should drink within a short time after opening. Also, when pouring into a cup with a bottle, the amount may be too high to drink right away, so some people want to use it over a long period of time.
It is also clear from the prior art that it is not possible to maintain pressure in the so-called spill-proof cup or hand held container and prevent the outflow of the fluid while moving with carbonic acid or hot fluid.

Accordingly, it is an object of the present invention to maintain a beverage in a container in a carbonated state during use, to facilitate access to the fluid and to prevent spills during movement. The present invention also applies to hot beverages, so that the fluid can be contained in a cup or container even if the air pressure rises due to the expansion of the air contained therein.

Drinking cups and hand held containers with a leak-free top cover in combination with spill-proof pipes and air outlets have been provided in many shapes and forms over the years to prevent leakage of fluid contained therein during temporary storage. The tube and air outlet have valves that allow fluid to flow out of the container or cup when drawn into the containment tube. The decrease in the fluid content in the vessel is replaced by air flowing through the secondary opening of the lid. This air outlet has a control valve which opens the air outlet when the pressure drops below the external air pressure due to the suction action in the pipe. As an example, an anti-spill feed / positive vessel having such characteristics can be found in US patent 5,079,013 by Bellanger; US Patent 5,542,670 by Morano; US Patent No. 5,186,347 to Freeman and the like. All of these inventions have been made primarily for the purpose of eliminating the outflow of fluids when babies or toddlers are throwing cups or containers or drinking on the move. In this patent specification, other references are made by other inventors but have the same or similar purpose in terms of eliminating the outflow of the fluid.

The applications here are only suitable for non-acidic fluids and cold beverages. If applied to a carbonated fluid, the pressure in the vessel rises and is unable to prevent leakage and spillage by pushing to open the valve. The same applies to hot beverages, i.e., the air above the fluid will heat up and expand and will push out of the fluid if the pressure in the container rises and cannot hold in an upright position. However, in US Pat. No. 5,542,670 of Morano, the outflow can be prevented by using a very strong resilient valve material, and in the case of Belinger US 5,079,013 using a very strong spring. However, there is a drawback that inhalation into the tube must be increased considerably, even if there is a degree of inhalation beyond the ability of a person, so opening the valve is impossible or at least cumbersome.

Since beverage cans containing carbonated beverages are commonly available to consumers today, adapters that clip onto the top of the cans after opening to make it easier to drink than to cover or drink directly into the cans. Are provided. Such properties are provided in the following specification. That is, U.S. Patent 4,796,774 by Nabinger, U.S. Patent 4,852,776 by Patton, U.S. Patent 4,883,192 by Krugman, U.S. Patent 5,071,042 by Esposito Palinchak) in US Pat. No. 5,947,324, European Patent 0870 685 to Igor and the like. The applications have the disadvantage that after opening the pressure is immediately released from the can and the carbon dioxide escapes from the fluid in a very short time and becomes less steaming and less inclined to drink. This means that all previously described applications are not suitable for carbonated drinks or hot drinks.

The present invention, in combination with many advantages over the prior art, can overcome all of the problems described above with respect to hermetically sealed cups and beverage cans. That is, it is possible to maintain the gas pressure to keep the fluid in a carbonated state, to facilitate the transport of the partially filled container and to prevent the fluid from flowing out during drinking or use while moving. In the case of beverage cans, the present invention provides additional hygiene advantages over the use of closed beverage cans and / or beverage adapters, such as, for example, provided by Krugman, US Pat. No. 4,883,192 and then other inventions. Has

Figure 7 shows a cross-sectional view of a third embodiment of the present invention by pushing and opening the valve rather than withdrawing the valve from the valve seat as in the first two embodiments when the suction pressure is applied to the tube.

8 shows a cross-sectional view of a fourth embodiment of the present invention which is identical to the third embodiment of FIG. 7 except for the protrusion of the membrane surrounding the tube.

One embodiment of the present invention includes a flow control element having a tube for sucking fluid from a cup, a metal beverage can, a bottle or a hand-held container that maintains a constant air pressure, wherein the fluid Is a carbonated beverage or a hot beverage such as coffee or tea. The flow control member is activated and promoted by suction on the tube, where the membranous member lifts a valve from the outside to the inside of the vessel. The inside of the container is expanded in the housing of the beverage cup by the air heated by the hot beverage or the gas pressure generated by the carbonated beverage is higher than the outside atmospheric pressure. The flow control member is a centrally penetrating membrane-type member connected to an essentially hollow valve stem that allows fluid to flow from the vessel into the tube through an opening in the tube, spring, and membrane filled with gas connected to the housing. It is composed of a valve stem guide having a valve seat and a valve made of a soft and resilient material. The valve is firmly fixed in the closed position by a spring pressing on the membrane and the valve stem in the valve seat direction. Since the valve is connected to the membrane through the valve stem, the movement of the membrane in the axial direction is represented by the same movement of the valve. As the suction in the tube reduces the pressure on one side of the membrane, the membrane displaces the valve, thereby opening the interior of the container, allowing fluid to flow. Fluid flows out of the vessel through a thin, flexible tube in the form of a straw on the inner surface of the vessel. The fluid thus reaches the valve opening from the bottom of the vessel through the valve stem and into the mouth through the membrane under the tube. The valve sealing area is substantially smaller than the effective surface area of the membrane. The small suction pressure difference on the top of the membrane typically results in a relatively large force opening the valve as compared to the pressure of the spring which keeps the valve closed. Therefore, the combination of the valve, the spring and the membrane is an essential part of the present invention that can operate the flow control member. The housing of the flow control member is either a gas tight portion that fits in a hole in the lid of an aluminum beverage can or an integrated portion of the gas tight lid of a beverage cup. The lower surface of the membrane is maintained at atmospheric pressure by an opening in the housing of the flow control member. When the pressure in the can or cup drops below atmospheric pressure by reducing the fluid height, the air inlet provided in the valve guide is only open in this case to replace the reduced total fluid volume with air. As mentioned above, the fluid member is closed from the outside into the interior of the hand-held container when not in use for a beverage under all surroundings and locations of the container.

Referring to the drawings, the present invention is generally described as being applied to a container such as a carbonated beverage can (water bottle) used for consumption, but the top cover is changed or adjusted to install the flow control member of the present invention.

1 shows a partially open external perspective view of a beverage can according to a first embodiment, having a flow control element located in the center of the top cover and extending inward from the outside of the can. However, the flow control member may be disposed off the center on the top cover.
The detailed configuration of this embodiment is shown in a partial cross-sectional view of FIG. 3, and an enlarged cross section of the flow control member is shown more clearly in FIG. 4.
The beverage can consisting of the cylindrical container 1, the bottom surface 2, the top cover 3 and the flow control member 4 receives the carbonated beverage 5 held at the gas pressure P3 6 by the carbonation process. It contains. This gas pressure is maintained in the carbonated state of the beverage for the pleasure of drinking the fluid (beverage) and is substantially higher than the external atmospheric pressure P2.
The flow control member 4 keeps gas pressure as long as necessary while allowing access to the fluid in the can. This is achieved by a housing 9 which is fixedly coupled to the top lid 3 of the beverage can and which has a barrier between the inside and the outside of the can.
On the other hand, the tube (7) is a gas seal coupled to the housing (9), holding the membrane (8) through the center in place.
The membrane 8 is tightly coupled to the housing 9 side in a gastight manner on the intake side, while on the other side it is maintained at atmospheric pressure. At the top and bottom of the membrane, a suitable space is provided to allow the membrane to move up and down several millimeters in the center, while the periphery is fixed. The membrane 8 is integrally coupled with the hollow valve stem 10 to allow fluid to pass therethrough. Specifically, the membrane 8 also has a center hole and is gas tightly coupled with the valve stem 10.
The housing 9 has a valve stem guide 14 which is an integrally extending tubular protrusion, which has an upper cylindrical portion 14b and a lower cylindrical portion 14a of two different diameters. It is penetrated into the container. The valve stem 10 is fixedly mounted to the lower cylindrical portion 14a of the valve stem guide 14, but has a sliding seal between the valve stem 10 and the lower cylindrical portion 14a of the valve stem guide 14. Clearances are provided that form. That is, the gap constitutes a slide fit that is sufficiently secured to allow movement of the valve stem 10 on one side but not to pass through the fluid or gas.
In addition, a valve seat 13 is formed below the lower cylindrical portion 14a of the valve stem guide 14. A valve 11 made of a resilient material is provided on the bottom of the valve stem 10 to close the nozzle 12 in the direction of the valve seat 13 with respect to the inside of the beverage can. A flexible tube (or straw) 15 is used to completely empty the can, which is secured to the nozzle 12 and descends to the bottom of the can.
The valve 11 is closed at the suction side of the flow control member by the spring 16. That is, the spring 16 pushes the membrane 8 and the valve 11 toward their seating position. The hollow valve stem 10 is lowered and narrowed at the bottom portion 17, while at least one hole 18 is formed in the narrowed slope to lift the valve 11 from the valve seat 13. Fluid passes through the aperture 18.
In addition, a small air passage 19 is provided in the housing 9 to ensure that the back pressure at the bottom of the membrane 8 is maintained at atmospheric pressure P1.
Accordingly, the flow control member 4 can be operated as follows.
First, suction into the tube 7 through the mouth causes the membrane 8 to move upwards. As a result, the valve 11 is lifted from the valve seat 13 against the pressure of the spring 16.
The magnitude of the force (opening force) for actuating and opening the valve 11 is multiplied by the pressure difference P1-P2 acting on the membrane 8 and the active surface area of the membrane 8, i.e. It is determined by adding the force by the pressure difference P3-P2 acting on the valve 11 to (P1-P2) x A, and removing the spring force F _spring .
F _open = (P1-P2) × A + (P3-P2) × a-F _spring
Where F _open is the opening force, "A" is 1 / 4.π.D ² of the effective surface area of the membrane, "a" is 1 / 4.π.d ² of the effective surface area of the valve, and "π" (pi) is 3.14, "D" is the active diameter of the membrane, "d" is the effective diameter of the valve, and "F _spring " is the spring force.
In order to keep the valve 11 closed, when not using the "flow control member", the spring force F _{spring needs} to be substantially larger than the force acting on the valve 11 by the internal pressure of the container. have.
However, the suction force generated by the membrane 8 to open the valve 11 needs to overcome the closing force of the spring 16 minus the force acting on the valve 11. This means that the effective surface area of the membrane 8 needs to be substantially larger than the flow area of the valve 11.
When the valve 11 is lifted from the valve seat 13, the fluid inside the can is forced outward by the pressure difference P3-P2. Where P3 is the gas pressure inside the can and P2 is the suction pressure inside the tube. When inhalation is made, fluid flows through the flexible tube 15 to the nozzle 12 and passes through the valve 11 and through the hole (s) 18 of the hollow valve stem 10 through the membrane inside the tube 7. It comes out of the upper surface of (8) and enters the mouth.
As soon as the suction operation is stopped, the pressure difference P1-P2 disappears and only the pressure of the spring 16 remains, so that the fluid passage is closed because the valve 11 is restored to the valve seat 13.
On the other hand, under some circumstances, by emptying the can, the internal pressure P3 can be greatly reduced and even smaller than the external atmospheric pressure P1. In this case, the suction pressure can open the valve but is insufficient to completely empty the beverage can.
In preparation for this situation, an air flow port 20 is provided which consists of one or more holes in the upper portion of the valve stem guide 14. These air outlets 20 are controlled by an elastic band 21 having a suitable width to generally completely cover the holes. That is, the elastic band 21 serves as a valve, and allows air to enter the area below the membrane 18 from the air passage 19 and then along the top of the valve stem guide 14. 20) through the inside of the can.
Due to this feature, substantially the internal pressure P3 of the can never falls below the external atmospheric pressure P1. Therefore, as shown in FIG. 4, the upper cylindrical portion 14b of the valve stem guide 14 is formed to be slightly expanded to allow air to pass therethrough.
In applying the flow control member as described above, the sanitary cover 29 is firmly fixed on the shoulder of the housing 9 in order to prevent the pipe 7 from being dirty when not in use and transported. do.

The individual components of the flow control member according to the first preferred embodiment as described above in Figs. 5A to 5E are shown. However, the present invention is not limited to the embodiment described above, but may be extended to an example to which the same principle is applied by using a through membrane for operating a valve.

2 and 6 is a second preferred embodiment showing that the flow control material is applied to the cup for preventing spillage beverage.
As shown, the top cover is firmly screwed into the cup or container. In this case, the housing 9 'of the flow control member 4' is an integral leak-proof member of the upper lid, whereby the carbonated beverage, the hot and cold beverage can be accommodated without the cup leaking after sealing. . In the case of hot beverages, the air above the fluid expands to increase the pressure in the cup or handle. For this embodiment, a perspective view of a partially open cup or container is shown in FIG. 2, while a partial cross-sectional view of that same embodiment is shown in FIG. 6. In the case of this embodiment, since the operating principle of the flow control member 4 is exactly the same as the description of the first preferred embodiment, this part is not repeated and only the changed part is described.

FIG. 6 shows a gas tight seal 24 made of an elastic material that prevents leakage of the container when filled with a beverage, hot or cold beverage, and with a top lid 23 that is screwed onto and detachable from the container 22. Or a container 22 made of plastic. In this second embodiment, the housing 9 'of the flow control member 4' is integrally molded with the top cover 23. As shown in FIG. Therefore, there is a slight difference from the flow control member of the beverage can. Tube 25 is removable to allow access to the flow control material inside for cleaning. The remaining parts are substantially the same as those used in the (aluminum) beverage cans of FIGS. 1, 3, 4 and 5.

Fig. 7 shows a third embodiment of the flow control member 4 ", and is applicable to containers such as beverage cans, bottles, beverage cups, etc. The most important difference from the other embodiments of the invention described above is the valve 11 Rather than withdrawing ") from valve seat 13", the valve 11 "is pushed open by suction pressure.
The third embodiment consists of the following parts.
First, an inverted membrane 8 "through the center is arranged opposite to the membrane of the above-described embodiment and moves in the opposite direction upon inhalation, which is installed to prevent the leakage of gas but is part of the tube 7". It has a protruding tube 26 "that can move in the axial direction within the cylinder 27" that constitutes the. The tube 7 "holds the inverted membrane 8" in place and forms a gas tight coupling structure with a valve holder 14 "having a seal 30" at its perimeter. The flow control member assembly is fixed to the upper portion of the container 1 "such as a beverage can, a bottle, a beverage cup, etc. by a spiral lid connection 31". The valve holder 14 "is formed with a valve seat 13", which, together with the valve 11 ", forms a sealing barrier between the inside and outside of the container 1" and does not allow fluid to pass through when not in use. The valve 11 "is connected with the inverted membrane 8" by the connecting piece 17 "through the valve stem 10". When there is no suction in the tube 7 ", the connecting piece 17" together with the inverted membrane 8 "retains the valve 11" on the valve seat 13 "so as not to leak gas, but the fluid during suction. The air outlet port 29 "forms a part of the tube 7, whereby the upper space of the inverted membrane 8" is reliably maintained at atmospheric pressure. If it is determined that the spring function of the inverted membrane 8 "is inadequate, a spring 32" may be additionally installed to help maintain the valve 11 "in the closed position. The operation of this embodiment of the present invention is as follows.
First, when inhalation is made to the tube 7 ", the pressure P2 in the space 28" will be reduced compared to the external pressure P1 above the inverted membrane 8 ". As a result, the inverted membrane 8 "moves downwards, eventually pushing valve 11" out of valve seat 13 "to open the fluid flow path from the interior of beverage container 1" to the mouth. If the pressure in the container 1 "drops below the outside atmospheric pressure by sucking the beverage from 1"), the valve 11 " Will be opened.
The above embodiment therefore requires a gas-tightly movable coupling of the cylinder 27 "and the protruding tube 26" of the inverted membrane in the tube 7 ". The control member 4 "may operate incorrectly. The solution to this is to put bellows, so-called O-rings, between the inverted membrane 8 "and the tube 7", but this has been found to be an obstacle.
Therefore, it is conceivable to considerably simplify this embodiment of the present invention by omitting all the tubes 7 "and leaving the protruding tube 26" of the inverted membrane as the tube. This fourth embodiment is shown in Fig. 8, which consists of the same components as shown in Fig. 7 except for the tube 7 ". The operation is also the same and need not be described any further.
Looking at the action of the force in the third and fourth embodiments as follows.
The magnitude of the force (opening force) for actuating and opening the valve 11 is determined by the pressure difference P1-P2 acting on the inverted membrane 8 "and the active surface area of the inverted membrane 8". ) Is determined by subtracting the force due to the pressure difference P3-P2 acting on the valve 11 "and subtracting the spring force F _spring .
F _open = (P1-P2) × A-(P3-P2) × a-F _spring
Where F _open is the opening force, "A" is the effective surface area of the inverted membrane, 1 / 4.π.D ² , and "a" is 1 / 4.π.d ² , the effective surface area of the valve. "π" (pi) is 3.14, "D" is the active diameter of the inverted membrane, "d" is the effective diameter of the valve, and "F _spring " is the spring force.
When the valve is pushed out of the seat by suction, the fluid in the container will be forced outward by the pressure difference P3-P2. Here, P3 and P2 are the pressure in the container and the suction pressure in the spout, respectively.
To overcome this pressure difference (P3-P2) (which means that F _open must have a positive value), the surface area (A) of the inverted membrane is substantially greater than the effective area (a) of the valve. Will be bigger.
The internal pressure P3 may reach a value substantially greater than the atmospheric pressure P1 (eg, eight times the atmospheric pressure).

According to the present invention of such a configuration, it is possible to keep the beverage in the container in a carbonated state for a long time, to prevent it from spilling while moving or falling, and is also applied to a beverage of high temperature, due to the expansion of the air contained therein, so that the air pressure Even if this rises, the fluid can be contained in a cup or a container.
