CZ6857U1 - Screw-type tap-head - Google Patents

Description

Commonly supplied plastic bottles with carbon dioxide screw caps (soda water, bicycles and many other soft drinks) are usually 1.5 or 21 liters in volume. This family pack is convenient for only a few to be consumed at a time. If some of the contents remain in the bottle for several hours, it will be destroyed by the leakage of carbon dioxide because the original cap is not tight. In addition, spilling may occur during pouring, especially if the full bottle is handled by children.

For easier handling when pouring beverages from these bottles, a screw-on tap head has been proposed which can be placed on the bottle instead of the cap. In essence, it has a thrust actuator, upon opening of which the contents of the bottle are forced out by the pressure of the gas inside, the thrust actuator being a single-arm lever pivotable about a pin and abutting the plug of the shut-off valve.

Such a starter is somewhat complicated in design and especially in manufacturing, resulting in possibly higher production costs.

The essence of the technical solution

The aforementioned drawbacks of the dispensing heads with a lever push closure are eliminated by the screw dispensing head according to the present invention, which is based on the fact that its actuating trigger is designed as a piston sliding on the valve body and abutting the valve plug. a discharge hose is attached to the space below the valve plug and an extended outlet throat is connected to the space above the valve plug.

BRIEF DESCRIPTION OF THE DRAWINGS

The figure shows a schematic cross-sectional illustration of a tap head according to the invention.

Exemplary embodiment

The most important part of the tap head is its valve plug 2, the lower part of which is provided with a bearing surface with a seal 4, which is pressed against the working surface of the valve body by a compression spring 7. The upper part of the plug 2 is provided with a shoulder in which the sealing ring 2 is mounted and is located in the upper part of the valve body. From the space above the seating surface of the plug 2, there is a neck, on which a flexible hose is fitted. The entire valve and plug mechanism 3 is inserted into a threaded segment which coincides with the thread of standard beverage bottles and which is screwed onto the bottle provided with a sealing surface 5 on the bearing surface. facing the mouth of the warhead. A discharge hose is provided on the lower part 6 of the valve body, the length of which is sufficient to the bottom of the bottle.

After the screw head is screwed onto the beverage bottle immediately

The cylinder contents remain under the pressure of the carbon dioxide contained. Pressing the trigger 1 overcomes the pressure of the spring 7, the valve plug χ moves down and opens the flow to the top of the valve body. The carbon dioxide pressure will push the beverage through the top of the valve into the hose mouth as long as the push trigger 1 is pressed down. When it is released, the spring 7 returns the plug χ and the flow is closed again. Industrial applicability

The tap head according to this technical solution is particularly useful in households, where it increases the culture of dining, facilitates the handling of beverages for children and eliminates the spillage of the beverage on the table. Its further advantage is the possibility of re-sealing the beverage and its use even after a certain period of time, without deteriorating it by leaking carbon dioxide.

Claims (1)
