Packaging head for opening part of barreled water barrel

Abstract

The invention relates to a packaging head for an opening part of a barreled water barrel. The packaging head for the opening part of the barreled water barrel comprises a hard shell part and a hard water leakage core part. Multiple self-locking clamping mechanisms are arranged on the inner wall of the hard shell part. Drive ends of the self-locking clamping mechanisms extend into inner holes. An internal thread is arranged on the inner wall of an inner enclosure part. The hard water leakage core part is connected in the hard shell part in a threaded manner and comprises a water outlet hole for a communicating vessel ejecting and pressing column to penetrate therein, a plug limited above the water outlet hole and longitudinally moving, and a pressure exertion mechanism used for elastically sealing the plug above the water outlet hole. The parts, fixedly connected with the opening part of the barrel, of the packaging head can be made of hard and healthy materials, the packaging head is assembled through matching between the parts, disassembly and assembly are convenient, installation is rapid and convenient, and self-locking can be achieved. The packaging head is automatically blocked through elastic force and is instantly opened after being placed in, the situation that a blocking plastic piece can hardly be ejected to be broken does not happen to the product, and the packaging head can be detached and repeatedly recycled.

Description

technical field [0001] The invention relates to a drinking water device, in particular to a packaging head for the mouth of a bottled water bucket. Background technique [0002] Bottled water refers to the drinking water installed on the water dispenser. The structure of the packaging head on the bottled water has been very simple for a long time. During production, the water is filled and then sealed with a soft plastic head before it can be sold. . When we buy drinking water, we only need to put the mouth of the drinking water bucket on the smart seat of the water dispenser, the top pressure column of the smart seat will break the blocked plastic sheet, and the bottled water can leak into the water dispenser normally . But at present, the packaging head on this drinking water bucket has the following deficiencies, which are difficult to overcome: 1. It is troublesome to install the packaging head into the mouth of the drinking water bucket and seal it. It needs injection...

Problems solved by technology

But at present, the packaging head on this drinking water bucket has the following deficiencies, which are difficult to overcome: 1. It is troublesome to install the packaging head into the mouth of the drinking water bucket and seal it. It needs injection molding, so that the plastic can be integrally formed and inserted; If the plastic material selection of the plastic head is not strict enough, many plastics soaked in hot water will easily release toxic substances when the water dispenser is heated. Now there are many brand bottled water on the market, it is difficult to control the quality standard of the plastic head, so there is Potential safety hazards of drinking water; 3. Due to quality control problems, the sealing piece in many soft plastic heads and its connecting periphery are too firm, and the top pressure column cannot break through the sealing plastic piece at one time, causing the water dispenser to bear Repeated top pressure sometimes causes the smart seat to break; 4. After the soft plastic head is used once, it cannot be reused, and the cost is high and the material is wasted. It is a one-time consumable; When the bottled water is used, the water will leak straight away, so it is troublesome to change the water when it is not finished
