Description

Injection blow molding material bottle

Technical Field

The utility model relates to a medicine container field especially relates to an injection blowing material bottle.

Background

New medicine is one of seven strategic emerging industries, and the development of high-quality and technically-advanced medical plastic bottles is an indispensable part of a new medicine development industry chain.

The current medical plastic bottles are various in types, and generally have the following defects:

firstly, the standards of various bottle mouths are not uniform, and the bottle mouths cannot be well matched with a pump;

secondly, the existing bottle mouth design part is difficult to achieve good sealing performance;

thirdly, the plastic bottle with good sealing performance needs great capping pressure when capping, and is not easy to assemble;

fourthly, the existing bottle has no specific requirements on the residual quantity of the liquid medicine.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides an injection blowing material bottle, can solve the problem that current medical plastic bottle leakproofness is poor, difficult assembly.

In order to solve the technical problem, the utility model discloses a technical scheme be: there is provided an injection blow molding material bottle comprising: the bottle comprises a bottle body, a bottleneck, a bottle opening and a bottle bottom, wherein the bottleneck is arranged at the top of the bottle body, the bottleneck is arranged between the bottle body and the bottle opening and is connected with the bottle body and the bottle opening, the bottle bottom is arranged at the bottom of the bottle body, the bottle body and the bottle bottom jointly form a cavity for containing liquid, a circle of sealing ribs are arranged on the upper end face of the bottle opening along the circumferential direction, a circle of inner boss protruding towards the inner side of the bottle opening is arranged on the inner side face of the top of the bottle opening along the circumferential direction, the upper end face of the inner boss is flushed with the upper end face of the bottle opening, and the outer side.

Preferably, the outer edge of the end face of the bottle mouth is provided with a chamfer.

Preferably, the chamfer is a round chamfer.

Preferably, a convex part protruding upwards is arranged in the middle of the bottle bottom.

Preferably, the ratio range between the height of the convex part and the wall thickness of the bottle body is as follows: 1:1 to 2: 1.

The utility model has the advantages that:

1. the sealing rib is added on the end face of the bottle mouth to enhance the sealing performance when the bottle mouth is matched with the gland;

2. a circle of inner bosses protruding towards the inner side of the bottle mouth is circumferentially arranged on the inner side face of the top of the bottle mouth, and the upper end faces of the inner bosses are flush with the upper end face of the bottle mouth, so that the contact area between the end face of the bottle mouth and the bottle cap is increased, and the sealing performance is further increased;

3. the outer side wall of the bottle opening is inclined outwards by 3-5 degrees relative to the axis of the bottle body, so that the pressure between the closed bottle cover and the side wall of the bottle opening is increased, and the sealing property is improved;

4. the outer edge of the end face of the bottle opening is provided with a chamfer, so that the bottle cover can be easily covered on the bottle.
