Description

BACKGROUND OF THE INVENTION

Field of the Invention The invention relates to a pressure device for a liquid food container, in particular a pressure device used to provide a metered quantity of liquid for a diet.

Description of the prior art

People often use a pressure device to remove a variety of liquids from containers. Because a pressure device has the advantages of easy operation and fixed flow rate, etc., such a pressure device is widely used for pumping liquid into containers. A liquid container and its pressure device cover a wide range of applications.

However, it is particularly described here a pressure device used in the food field. In the food industry, it is not necessary that cooking, seasoning (as in the case of syrup or wine, etc.), adding different types of ingredients (as in the case of juices concentrated fruit, etc.) or condiments are precise, since in just under a minute it can be prepared a delicious food. Therefore, a pressure device for a food container implies a more rigorous control. For example, a food pump, disclosed in US Pat. No. 5,375,746, comprises two ball valves arranged mainly in the valve body. In the pressing process, the two ball valves respectively correspond to the opening or closing of an outlet and an inlet under pressure to form a pressing pump structure. However, since the balls roll freely in the ball chambers, it is not certain that the outlet and the inlet can be completely blocked. If the balls are not really spherical, it is difficult to completely close the exit and entry. For this reason, it can easily be that the interior is not airtight, so that the liquid leaks out of the delivery ducts and is thus expelled with splash or even expelled back into the nozzle. This is annoying for the user. Because the pressure device is widely used, a pressure device having improved operating characteristics and preventing liquid from remaining on the nozzle is an important desire for those involved in the industry.

DETAILED DESCRIPTION

Referring first to Figures 1 and 4 to 5, it appears that a pressure device is installed on a lid B of a container A. The pressure device comprises a press head 1, a compression member 2 , a chancre 3 for storing liquid, a first leakage valve 4, a second leakage valve 5, and a liquid outlet 6.

The pressing head 1 is movably disposed on the lid B and intended to be pressed by a user, so that the pressing head 1 is moved relative to the lid B to activate the liquid outlet.

The compression member 2 is correspondingly assembled at one end of the pressing head 1, to a piston 21 and a main elastic piece 22. The compression piece 2 is thus able to be driven by the press head 1 to allow the main elastic piece 22 to exert a compressed release action and drive the piston 21 so as to move the latter.

The liquid storage chamber 3 is disposed inside the pressure device and has a liquid suction port 31 and a liquid conduction port 32 at both ends thereof. The first leakage valve 4 is correspondingly mounted on the liquid suction port 31, the first leakage valve 4 comprising a first attachment seat 41. A first valve stem 42, which can be moved, is integrated to the first attachment seat 41. A first resilient member 43 is engaged on the first valve stem 42 and is located between the first attachment base 41 and a first valve head 421. The first valve head 421 is correspondingly , able to seal the liquid suction port 31 or to be separated from the liquid suction port 31. The second leakage valve 5 is correspondingly mounted on the liquid-conducting port 32 and has a second attachment seat 51. A second valve stem 52 is movably integrated with the second attachment seat 51. The end of the second valve stem 52 forms a second valve head 521. A second elastic member 53 is engaged on the second valve stem 52 and is located between the second attachment seat 51 and the second valve head 521. The second head of Valve 521 is correspondingly capable of sealing the liquid conducting orifice 32 or of being separated from the liquid conducting orifice 32.

The liquid outlet 6 is connected to the second leakage valve 5 and communicates with the liquid conduction port 32. The liquid outlet 6 is used to conduct the liquid inside the container A until it flows out of the container. When actually used, the pressure device for a liquid food container according to the present invention is mainly used for various fields of use, such as adding a sugar solution to beverages, concentrates, adjusting a wine dosage for a cocktail, etc., by extracting the liquid from the container, and the liquid is adapted to be contained in different types of containers. Some examples are described below.

Example 1

With reference to FIGS. 1 to 7, it appears that the pressing head 1 is provided with a portion 11 forming a rod penetrating into the cover B. An end of the rod portion 11 is correspondingly integrated with an outer tube 7, and one end of the outer tube 7 is locked to the lid B. The compression member 2 is correspondingly mounted inside the outer tube 7. The piston 21 of the compression member 2 is provided with an actuating rod 23. One end of the actuating rod 23 is securely connected to the pressing head 1 and the actuating rod 23 is provided with an upper positioning member 24 and a lower positioning member. A main elastic member 22 is engaged outside the actuating rod 23 and is located between the upper positioning member 24 and the lower positioning member. The other end of the outer tube 7 is lockedly connected to a connecting seat. 8. The liquid storage chamber 3 is disposed in the connecting seat 8. The connecting seat 8 has a first opening 81 corresponding to the first attachment seat 41 of the first leakage valve 4. A first passage 44 between the first seat 41 and the first opening 81 communicates with the chamber 3 for storing liquid. The liquid suction port 31 is disposed at the other end of the connecting seat 8 opposite to the first opening 81. The connecting seat 8 has a second opening 82 corresponding to a locking seat 9. The orifice 32 liquid conduction is disposed on the locking seat 9 and communicates correspondingly with the liquid storage chamber 3. The locking seat 9 is correspondingly assembled to the second attachment seat 51 of the second leakage valve 5, and the second valve head 521 corresponds to the liquid conducting port 32 on the locking seat 9. A second pass 54 located between the second attachment seat 51 and the second opening 82 communicates with the outlet 6 of liquid. The liquid outlet 6 is disposed on one side of the cover B, and a pipe 10 is engaged on the outside of the locking seat 9. The pipe 10 is connected to the outlet 6 of liquid and leads thereto.

The structures of the first leakage valve 4 and the second leakage valve 5 are substantially the same, and the difference is that the assembly positions are different. Referring to Figures 2 and 3 and 6 and 7, it appears that an internal threaded portion a is arranged on an inner diameter of the first opening 81 of the connecting seat 8. The first attachment seat 41 is a seat body with a flattened surface on both sides thereof, and an external threaded portion b is provided on the outside of the first fastening seat 4L. When the first fastening seat 41 is locked at the inner diameter of the first opening 81, the first passage 44 located between the first attachment seat 41 and the first opening 81 is adapted to be connected to the liquid storage chamber 3. Similarly, an inner threaded portion a is disposed on an inside diameter of an opening 91 of the locking seat 9, and the second attachment seat 51 is a seat body having a flattened surface on both sides and an outer threaded portion. b is arranged on the outside of the second fixing seat 51. When the second fixing seat 51 is locked at the inner diameter of the second opening 82, the second passage 54 located between the second fixing seat 51 and the second opening 82 is adapted to be connected to the outlet 6 of liquid. In addition, the first valve head 421 and the second valve head 521 are each in the form of a tapered seat which is adapted to close tightly the liquid suction port 31 and the liquid conduction port 32 using a conical design. In addition, a washer C is disposed outside the first valve head 421 and the second valve head 521 respectively, to allow the first valve head 421 and the second valve head 521 to communicate with the valve. suction port 31 and the liquid conduction port 32 to obtain more sealing effect, so that this orifice does not leak.

The effective operation of Example 1 is illustrated in Figures 6 and 7. When the cover B initially covers the container A filled with liquid, the internal space, such as the liquid storage chamber 3, in a state of depression is capable of being filled with liquid by repeatedly pressing on the pressing head 1. After the pressing head has been pressed downwards, the rod portion 11 drives the actuating rod 23 and the piston 21 7. When the lower positioning member abuts against a narrowed portion 71 of the outer tube 7, the main elastic member 22 of the compression portion 2 is pressed. The piston 21 pushes the gas in the outer tube 7 through the first passage 44 and pushes the liquid in the liquid storage chamber 3 to the second leakage valve 5. Simultaneously with the thrust of the gas on the liquid, the first head of valve 421 of the first valve stem 42 of the first leakage valve 4 is also able to seal the liquid suction port 31 so that the liquid present in the container A will not counterbalance the suction port 31 of liquid. The liquid present in the liquid storage chamber 3 displaces the second valve stem 52 of the second leakage valve 5 so as to compress the second elastic member 53 to disengage the second valve head 521 from the orifice 32 of liquid conduction. The liquid is led out of the liquid outlet 6 through the second passage 54 and the pipe 10 from the liquid conduction port 32. On the contrary, after releasing the pressing head 1, the piston 21 is returned to the original position by the elastic force of restoration of the main elastic member 22 of the compression member 2. Under suction, the first valve stem 42 of the first leakage valve 4 is driven to move on the first attachment seat 41 by the first passage 44. The first resilient member 43 is compressed to disengage the first valve head 421 from the first port 31 for suction of liquid. Simultaneously with the implementation of this action, the original restoring attraction force attracts the second valve stem 52 of the second leakage valve 5 so that it moves backwards and the second valve head 521 comes sealingly close the liquid conduction port 32. Simultaneously, the liquid present in the container A is sucked into the liquid storage chamber 3 from the liquid suction port 31 by suction due to the vacuum.

Example 2

With reference to FIGS. 8 to 10, it appears that the pressing head 1 is assembled on a hollow tube 12, one end of the hollow tube 12 penetrates into the cover B and is housed correspondingly in an outer tube 7, and one end the outer tube 7 is locked on the cover B. A liquid storage chamber 3 is formed in the outer tube 7. The end of the hollow tube 12 at the outer tube 7 corresponds to the piston 21 which locks the compression part 2 The liquid conducting orifice 32 is arranged at the lower part of the piston 21. The second leakage valve 5 is installed inside the piston 21. The second fixing seat 51 is correspondingly arranged on an opening The base of the outer tube 7 is correspondingly provided with a base 92. The liquid suction port 31 is arranged at a lower part of the base 92 and communicates with inside the container A. The first leakage valve 4 is mounted inside the base 92, so that the first attachment seat 41 is correspondingly arranged on the base 92. The upper positioning member 24 and the lower positioning member 25 are arranged on the two respective ends of the main elastic member 22. The upper positioning member 24 is located under the piston 21 and has an upper perforation 241 corresponding to the orifice 32 of conduction of liquid. The lower positioning member 25 is located above the base 92 and has a lower through hole 251 corresponding to the liquid suction port 31. The liquid outlet 6 is disposed on the hollow tube 12 and communicates with the liquid conduction port 32.

The structures of the first leakage valve 4 and the second leakage valve 5 are substantially the same, and the difference between them is that the assembly locations are different. With reference to FIGS. 8 to 10, it appears that an internal threaded portion a is arranged on an internal diameter of an opening of the base 92, and that the first attachment seat 41 is a base having a flattened surface on two sides, and an outer threaded portion b is disposed on the outside of the first attachment seat 41. When the first attachment seat 41 is locked to the inside diameter of the opening, the first passage 44 located between the first attachment seat 41 and the opening is adapted to be connected to the liquid storage chamber 3. Also, an inner threaded portion a is provided on an inner diameter of the opening of the piston 21. The second attachment seat 51 is a seat body having a flattened surface on two sides, and an outer threaded portion b is disposed on the outside of the second fixing seat 51. When the second fixing seat 51 is locked to the inside diameter of the opening, the second passage 54 between the second fixing seat 51 and the second opening 82 is able to be connected to the outlet 6 of liquid. The design of the shape of the valve head is in accordance with Example 1.

The effective operation of Example 2 is illustrated in Figures 8 to 10. When the cover B initially covers the container A filled with liquid, the internal space, such as the liquid storage chamber 3, in a state of depression , is capable of being filled with liquid by repeatedly pressing on the pressing head 1. After pressing the pressing head 1, the hollow tube 12 causes the piston 21 to move in the outer tube 7. When the organ positioning 251 abuts against the narrowed portion 71 of the outer tube 7, the main elastic member 22 of the compression member 2 is compressed. The piston 21 pushes the liquid present in the liquid storage chamber 3 of the outer tube 7 to allow the first valve head 421 of the first leakage valve 4 to seal the liquid suction port 31, so that the liquid present in the container A will not flow towards the liquid suction port 31 and will return to the liquid storage chamber 3. At the same time, the liquid present in the liquid storage chamber 3 is pressed upwards by the first leakage valve 4 at the lower part of the outer tube 7 to pass through the upper perforation 241 in the upper positioning member 24 and moving the second valve head 521 upwardly to compress the second elastic member 53. The liquid passes through the second passage 54 from the hollow tube 12 and through the liquid outlet 6, so as to be directed outwards. . On the contrary, after releasing the pressing head 1, the piston 21 is returned to the original position by the elastic force of restoring the main elastic member 22 of the compression member 2. Under suction, the first valve stem 42 of the first leakage valve 4 is driven by the first passage 44 to move on the first attachment seat 41, and the first resilient member 43 is compressed to disengage the first valve head 421 from the suction port 31 liquid. At the same time that this action is performed, the gravity, which is found, attracts the second valve stem 52 of the second leakage valve 5 to go back and allow the second valve head 521 to close the orifice 32 hermetically. conduction of liquid.

The first valve stem 42 of the first leakage valve 4 is driven to move on the first attachment seat 41 through the first passage 44. The first resilient member 43 is compressed to disengage the first valve head 421 from the orifice 31 for suction of liquid. At the same time as this action is performed, the original reset pulling force attracts the second valve stem 52 of the second leakage valve 5 so that it comes back and allows the second valve head 521 to seal the liquid conduction port 32. At the same time, the liquid in the container A is sucked into the liquid storage chamber 3 from the liquid suction port 31 by suction under vacuum. Simultaneously, the liquid in the container A is sucked into the liquid storage chamber 3 from the liquid suction port 31, via the first passage 44 and the lower perforation 251, by suction under vacuum.

With reference to FIG. 11, it also appears that notches 242 and 252 are arranged in the upper positioning member 24 and the lower positioning member 25 corresponding to the main elastic member 22, and the notches 242 and 252 are used to position the main resilient member 22. The invention has the following advantages: 1. The present invention utilizes the design of the valve heads of the first and second leachate valves to completely seal the port liquid suction and the liquid conduction port to prevent the liquid from flowing back. Thus, in the process of pressing and releasing pressure, the internal ducts form a state of depression without discoloration. This improves the problem that the traditional ball is not able to seal the outlet, resulting in the phenomenon of drip, and effectively achieves an anti-drip effect. 2. As indicated above, when the ducts form a state of complete depression, in the absence of pressing action, the suction is able to be used to completely absorb the liquid present in the ducts. Even if the container is shaken, there will be no dripping or spilling, thus avoiding splashing. 3. The main elastic member according to the present invention is adapted to be adjusted by adjusting the thickness and length of the adjustable pressure device.
