Reusable Siphon Head for Standard Beverage Bottles

Abstract

A reusable Siphon Head which has a helical threaded opening that allows to install it on standard beverage bottles. The Siphon Head enables to dispense carbonated beverages multiple times from the same beverage bottle with minimal loss of gas pressure. The Siphon Head has a screw based valve which enables to achieve gradual and smooth control of beverage outflow and also to apply high blocking pressure with only small manual effort. The Siphon head has a simple structure with minimal number of parts which is suitable for inexpensive plastics mass production and assembly. The Siphon Head does not have any metallic parts. The high pressure blocking allows for long term beverage storage with minimal pressure loss.

DETAILED DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 depicts a 3D isometric drawing of an embodiment of our screw based siphon head 101A which is installed on a beverage bottle 106A. The siphon head's main structure 101A has a screw 108A pushing a plug 108B (shown in FIG. 2) which is used to block the flow in the siphon head's valve. The screw 108A has a rotating member 108C which is used as a handle which facilitates manual rotation of the screw 108A. The rotating member 108C which is depicted in FIGS. 1, 2, 3, 4 has the shape of a flat bar. However, the rotating member 108C could assume the shape of a disc or any other shape which facilitates manual turning of the screw 108A. The siphon head's main structure 101A has a dispensing nozzle 101B which conducts the outflow of the beverage when the siphon head's valve is open.

[0024] FIG. 2 illustrates a cross section side view an embodiment of our screw based siphon head which is installed on a beverage bottle 106A. The siphon head's main structure 101A includes a dispensing nozzle 101B, a conical control opening 101D, a helical screw threading 101G, which fits the threading of the screw 108A, a cylindrical opening with helical threading 101C, which fits helical threading of standard beverage bottle openings 106B and a flange 101E, which is used to attach the pipe 103A to the siphon head's main structure 101A using the annular groove 103C. The siphon head's main structure 101A has a chamber 101H and also has a screw 108A pushing a conical plug 108B which is used to block the outflow from the conical control opening 101D. The conical plug 108B and the conical control opening 101D form the siphon head's valve. The screw 108A has a rotating member 108C which facilitates manual turning of the screw 108A. The siphon head's main structure 101A has a dispensing nozzle 101B which conducts the outflow of the beverage diagonally down when the siphon head's valve is open. A helical threaded cylindrical opening 101C is designed for fastening the main structure of the siphon head 101A to the bottle 106A using fitting threaded bottle opening 106B. The helical threaded cylindrical opening 101C fits the helical threaded cylindrical opening 106B (a threaded pipe opening) of standard beverage bottles and allows fastening the main structure of the siphon head 101A to the helical threaded cylindrical openings of standard beverage bottles, thus sealing the bottle and blocking outflows of gas or beverage. Improved sealing of the siphon head 101A to the bottle 106A is facilitated by the washer 105 which is made of flexible and resilient material. The screw 108A can be turned by the user using a rotating member 108C, which is attached to the upper end of the screw 108A. The conical plug 108B which is made of resilient material, is rotatably connected to the lower end of the screw 108A by a flexible nail head 108D, thus enabling the screw to rotate further even when the conical plug 108B is already touching the conical control opening 101D. Further screw rotation increases the outflow blocking pressure of the conical plug 108B on the conical control opening 101D. The bottle has pressurized beverage fluid 102 under pressurized gas 107. The conical plug 108B which is fitted into a conical control opening 101D form a valve. At the closed position of the valve, the conical plug 108B is pressed against the conical control opening 101D and blocks the outflows of beverage 102 which is pushed by the pressurized gas 107 via the pipe 103A and the pipe's openings 103B and 103C. The conical plug 108B is held at a closed position by a helical threading screw 108A which is screwed through the helical threaded opening 101G in the siphon head's main structure 101A. The screw 108A is designed to push the conical plug 108B downwards and to block the conical control opening 101D when the valve is in closed position. When the user wants to pour some beverage, the user unscrews the screw 108A by turning the rotating member 108C this raises the conical plug 108B and releases the pressure on the conical control opening 101D and the beverage 102 which is pushed by the pressurized gas 107 flows outside via the pipe 103A and via the bottom opening 103C and through the conical control opening 101D into the chamber 101H which feeds the dispensing nozzle 101B. The pipe 103A is attached to the siphon head's main structure 101A by an annular groove 103D, which fits the round flange 101E. The pipe 103A descends from the bottom opening 103C all the way to the inner bottom of the beverage bottle 106A (except for a small gap) thus enabling to empty most of the beverage from the bottle since the pressurized gas 107 pushes the beverage 102 upwards through the pipe 103A openings 103B and 103C, through the conical control opening 101D and through the chamber 101H which feeds the dispensing nozzle 101B

[0025] The assembly of the siphon head is quite simple. First the conical plug 108B is installed at the bottom of the screw 108A by pushing the resilient nail head 108D into the fitting cavity at the bottom of the screw 108A. Next, the screw 108A is screwed into the siphon head's main structure 101A via the screw threading 101G. Notice that the plug 108B has narrower diameter than the inner diameter of the screw threading 101G to allow it to pass through the threading 101G. Finally, the pipe 103A is attached to the siphon head's main structure 101A by installing the pipe's annular groove 103C onto the round flange 101E.

FIG. 3 illustrates an alternative embodiment of siphon head with a plug 108B with planar bottom and control opening 101D with a shape of a planar ring. Except for the change in the plug 108B and the control opening 101D shapes, FIG. 3 describes the same siphon head as in FIG. 2.

[0027] FIG. 4 describes a cross section side view an embodiment of our screw based siphon head which is installed on a beverage bottle. FIG. 4 illustrates an alternative embodiment of siphon head with convex shape of the plug 108B and matching concave shape of the control opening 101D. Except for the change in the plug 108B and the control opening 101D shapes, FIG. 4 describes the same siphon head as in FIG. 2.
