DESCRIPTION

Pressure device for liquid food container

Background

Field of the Invention

The invention relates to a pressure device of a liquid food container, in particular a pressure device used as a liquid dosed for dietary food.

Description of the related technique

A pressure device is often used to extract a variety of liquids in containers. Since the pressure device has the advantages of simple operation and a fixed output flow, etc., the pressure device is widely used in the pumping of liquid containers. Liquid containers and their pressure devices cover a wide variety of applications.

However, a pressure device used in the feed category is especially described herein. In the dietary industry, regardless of the preparation, it is necessary to be prices in the dressing (such as syrup or wine, etc.), in the addition of various kinds of ingredients (such as concentrated fruit juice, etc.) or in condiments , since less than a minute will lose its delicious character. Therefore, the pressure device of a vessel is a stricter control. For example, in a feed pump, disclosed in US 5375746, two ball valves are arranged primarily in the valve body. In the pressure procedure, the two valve balls correspond respectively to the opening or closing of an outlet and an inlet under a pressure to form a structure of a pressure pump. However, since the balls roll freely in the ball spaces, it cannot be ensured that the exit and the entrance can be completely blocked. If the balls are not a true sphere, it is difficult for the exit and the entrance to be completely sealed. Because of this, it is easy not to empty inside, so that the liquid leaks from the pipes and therefore splashes around or even splashes back to the nozzle. This is a headache for the user. Since the pressure device is widely used, a pressure device with improved operability characteristics and preventing liquid from remaining in the nozzle is an important issue for those involved in the industry

When cover B initially covers the container A filled with the liquid, the internal space, such as the liquid storage chamber 3, in a vacuum state that can be filled with liquid by repeatedly pressing the pressure head 1. After the head is pressed down of pressure 1, the rod part 11 drives the drive rod 23 and the piston 21 to move in the outer tube 7. When the lower positioning element 25 abuts against a decrease section 71 of the outer tube 7, it squeezes the main elastic element 22 of the compression part 2. The piston 21 pushes the gas in the outer tube 7 through the first conduit 44 and pushes the liquid in the liquid storage chamber 3 towards the second leakage valve 5. Simultaneously at the gas thrust of the liquid, the first valve head 421 of the first valve stem 42 of the first leakage valve 4 can also hermetically seal the hole. or liquid suction 31 so that the liquid in the container A does not go against the flow of the liquid suction hole 31.

Under vacuum suction conditions, the first rod of valve 42 of the first leakage valve 4 is operated to move on the first fixing seat 41 through the first conduit 44. The first element The elastic 43 is compressed to disengage the first valve head 421 from the liquid suction hole 31. At the time this action is performed, the attractive attraction force attracts the second valve stem 52 of the second leakage valve 5 to move back and allow the second valve head 521 to tightly seal the liquid conduction hole 32. At the same time, the liquid in the container A is sucked into the liquid storage chamber 3 from the suction hole of liquid 31 by vacuum suction.

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. Please refer to figures 8-10. An inner thread part a is arranged in an inner diameter of an opening of the base 92, and the first fixing seat 41 is a base having a flattened surface on both sides, and an outer thread part b is arranged in the outside of the first fixing seat 41.

The design of the shape of the valve head is as in Example 1.

For actual operation in Example 2, see Figures 8-10. When the cover B initially covers the container A filled with the liquid, the internal space, such as the chamber of liquid storage 3, in a vacuum state that can be filled with liquid by repeatedly pressing the pressure head 1. After pressing the pressure head 1 down, the hollow tube 12 drives the plunger 21 to move in the outer tube 7. When the positioning element 251 abuts against the decrease section 71 of the outer tube 7, the main elastic element 22 of the compression part 2 is pressed. The piston 21 pushes down the liquid in the storage chamber. liquid storage 3 of the outer tube 7 to allow the first valve head 421 of the first leakage valve 4 to seal the liquid suction hole 31 tightly, so that the liquid in the container A does not flow into the orifice of liquid suction 31 and flow back to the liquid storage chamber 3. At the same time, the liquid in the liquid storage chamber 3 is pressed upwardly by the first mere leakage valve 4 in the lower part of the outer tube 7 to pass through the upper perforation 241 in the upper positioning element 24 and move the second valve head 521 upwards to compress the second elastic element 53. Liquid passes to through the second conduit 54 from the hollow tube 12 through the liquid outlet 6 to be driven outward. On the contrary, after the release of the pressure head 1, the piston 21 is restored by the elastic recovery force of the main elastic element 22 of the compression part 2. Under vacuum suction, the first valve stem 42 of the first anti-leakage valve 4 is actuated by the first conduit 44 to move on the first fixing seat 41 and the first elastic element 43 is compressed to disengage the first valve head 421 from the liquid suction hole 31. At the time this action is performed , the recovery severity attracts the second valve stem 52 of the second leakage valve 5 to move back and allow the second valve head 521 to seal the liquid conduction hole 32 tightly.

The first valve stem 42 of the first anti-leakage valve 4 is operated to move on the first fixing seat 41 through the first conduit 44. The first elastic element 43 is compressed to disengage the first valve head 421 from the orifice. liquid suction 31. At the time this action is performed, the restoring attraction force attracts the second valve stem 52 of the second anti-leakage valve 5 to travel back and allow the second valve head 521 to seal tightly the liquid conduction hole 32. At the same time, the liquid in the container A is sucked into the liquid storage chamber 3 from the liquid suction hole 31 by the vacuum suction. Simultaneously, the liquid in the container A is introduced into the liquid storage chamber 3 from the suction hole of liquid 31 by means of the first conduit 44 and the lower perforation 251 by vacuum suction.

The invention has the following advantages:

1. The present invention uses the design of the valve heads of the first and second anti-leakage valves to completely seal the liquid suction orifice and the liquid conduction orifice to prevent the liquid from flowing back. So in the process of pressure and release, the internal pipes form a vacuum state without fading. This improves the problem that the traditional ball cannot seal the outlet where the dripping phenomenon is sealed, to effectively achieve the anti-drip effect.

2. As indicated above, when the pipes form a state of complete vacuum, subjected to a non-pressure action, vacuum suction can be used to completely absorb the liquid in the pipes. Even if the container is shaken, there will be no dripping or spilling of liquid to prevent the splashing effect.

3. The main elastic element of the present invention can be adjusted by adjusting the thickness and length of the adjustable pressure device.
