Most of the packaging methods are different manufacturers and places for producing containers and filling the solution in the packages, and the transportation and the storage cost of the packages are high. The production of different bottle and liquid manufacturers and the condition that the bottle production and filling are not the same production line can cause a plurality of production processes to be added in the middle, and a large amount of manpower and material resources are wasted.

Especially for some products (such as buffer solution of new coronavirus detection reagent, sample lysate and the like) with small capacity and large quantity, space transfer and warehouse cost are increased by filling and separating bottles and liquid, and processes of filling, bottle cap screwing and the like are complex and easy to leak liquid. Therefore, the invention tries to provide a production process which has the advantages of convenient production, low cost, large-scale production, simple production process and integrated formation of buffer bottle and filling.

Disclosure of Invention

In order to achieve the purpose, the invention adopts the technical scheme that:

a process for preparing and filling a buffer bottle comprises the steps of heating a transparent composite material, cutting by an easily-torn line, blow molding, filling, sealing the tail, cutting and the like.

The composite material is a PVC/PE composite material, PE is a heat sealing surface, and the thickness of the PVC/PE composite material is 0.25mm-0.35 mm.

The composite material is softened by heating so as to be convenient for blow molding, and the heating temperature range is 115 ℃ and 130 ℃.

The cutting depth of the easy-to-tear lines on the front and rear composite materials of the buffer bottle is 0.02mm-0.1mm, the easy-to-tear lines are positioned on the same horizontal line, and the easy-to-tear lines of the front and rear composite materials are overlapped after blow molding.

And in the blow molding, after the heated composite material is thermally sealed by a mold, the specific upper half body appearance of the buffer bottle is formed under the blow molding of compressed air: the bottle comprises a head seal, a bottle opening, an easy-to-tear line, a bottle body and a bottle tail.

During filling, the filling liquid is filled into the bottle body from the bottle tail.

And after the end sealing and filling are finished, the bottle end is heated and sealed, and the heat sealing temperature is 125-140 ℃.

The cutting is carried out by cutting into the required shape through a cutting knife with a specific shape.

The scheme is adopted: the buffer bottle of the invention has relatively simple production process, is integrated with production and filling, saves cost and can be produced in large scale.

The invention has the beneficial effects that:

1. the forming, filling and cutting of the buffer bottle are integrated, so that the expenses of warehouse and bottle transfer are saved, and the cost is saved.

2. The molding and filling are integrated, the production process is optimized, and the production efficiency is improved.

3. The design of easy-to-tear lines, when the product is used, the head seal position is easy to break, the bottle mouth is exposed, and the content is taken out.

4. The product is integrated into one piece, and the leakproofness is good, and the weeping rate is low.
