A packaging structure on a drinking water bucket

Abstract

The invention relates to a sealing and packing structure on a drinking water barrel. The sealing and packing structure on the drinking water barrel comprises a hard shell part and a hard water leakage core part, wherein the hard shell part comprises an external enclosing part, an internal enclosing part and a connection ring part; the connection ring part and the inner side of the internal enclosing part jointly form an inner hole; the hard water leakage core part is detachably connected to the inner hole of the hard shell part; the hard water leakage core part comprises a blocking mechanism which is characterized in that water leakage can be realized after an ejection post of a smart base penetrates through a water outlet; the connection ring part is provided with multiple clamping mechanisms used for clamping the mouth part flange of the drinking water barrel; the input ends of the clamping mechanisms are located in the inner hole; and when the hard water leakage core part is arranged in the inner hole, the peripheral surface of the hard water leakage core part ejects the input ends of the clamping mechanisms so as to drive the multiple clamping mechanisms to clamp the flange. The component, which is fixedly connected with the mouth part of the drinking water barrel, of the sealing and packing structure can be manufactured by adopting a hard and healthy material; the structure is novel; disassembly and assembly are convenient; assembly is rapid and convenient; self-locking can be realized; and the sealing and packing structure can be repeatedly recycled.

Description

technical field [0001] The invention relates to a drinking water device, in particular to a packaging structure on a drinking water barrel. Background technique [0002] The drinking water barrels installed on the water dispenser have a very single structure for a long time. Generally, during production, the filling water is filled, and then the soft plastic head is sealed, and then it can be sold. When we buy drinking water, we only need to insert the mouth of the drinking water barrel into the smart seat of the water dispenser. The top pressure column of the smart seat will break the blocked plastic sheet, and the drinking water barrel 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. If the plastic material selection of the soft plastic head is not strict enough, many plastics will be easily released when the water dispenser is heated. Toxic s...

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. If the plastic material selection of the soft plastic head is not strict enough, many plastics will be easily released when the water dispenser is heated. Toxic substances, there are a lot of brand bottled water on the market now, it is difficult to control the quality standards of plastic heads, so there are potential drinking water safety hazards; 2. Due to quality control problems, the sealing pieces in many soft plastic heads and their connections The periphery of the wall is too firm, and the top pressure column cannot break through the blocked plastic sheet at one time, causing the water dispenser to withstand multiple top pressures, and sometimes the smart seat is broken; 3. After the soft plastic head is used once, it cannot Reuse, high cost and waste of materials, is a one-time consumable; 4. When the unfinished bottled water is pulled out, the water will leak straight, so it is troublesome to change the water when it is not finished
