Packaging structure on barreled drinking water barrel

Abstract

The invention relates to a packaging structure on a barreled drinking water barrel. The packaging structure comprises a rigid installation part and a rigid water leaking core part which are fixedly embedded in an opening of the water barrel. A first sealing ring and a plurality of expansion mechanisms corresponding to the inward concave edge are arranged on the periphery of the rigid installation part. The first sealing ring is located on the inner side of the expansion mechanisms. An inner hole penetrating through the drinking water barrel is formed in the center of the rigid installation part. The rigid water leaking core part is detachably connected to the interior of the inner hole of the rigid installation part. The rigid water leaking core part comprises a water drainage hole allowing a base abutting-pressing column to penetrate into, a plug which is limited at the position above the water drainage hole and moves in the longitudinal direction, and a pressure applying mechanism used for making the plug elastically seal the position above the water drainage hole. The packaging structure performs plugging through elastic force, can be made of rigid healthy materials, is novel in structure and can be 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
