Abstract

The utility model relates to a cap of a transfusion bottle, which is composed of a plastic inner cap, a butyl rubber pad and a plastic outer cap. The utility model is characterized in that a locating ring of the lower end of the plastic inner cap is welded with the bottle opening of a plastic transfusion bottle after being tightly clamped in the inner position of the bottle opening; the quality of the liquid in the bottle is ensured; the upper end of the plastic outer cap adopts an ultrathin body plane design. The utility model has the advantages of reasonable structure, convenient use, no use of modification stuff, low cost, adoption of modern high-efficiency appliances for production, simple manufacture and high productive efficiency.

Description

Infusion bottle lid

This utility model relates to a kind of Infusion bottle lid, especially can mate the Infusion bottle lid of sealing with plastic infusion bottle.

Affiliated technical field: Infusion bottle lid is to adopt nonpoisonous and tasteless plastic raw materials to make, and is used for the sealing of medical infusion plastic bottle coupling.The enclosing cover of existing pharmaceutical infusion plastic bottle coupling, there is a draw ring upper end, and plastics inner cap lower end does not have centring ring, is to make with modified materials, and cost height, production efficiency are low.

Background technology: prior art disposable infusion plastic bottle closure, plastic outer cover upper end have a draw ring, and plastics inner cap lower end does not have centring ring, because of the structural design of plastic outer cover, can only make and with traditional device fabrication, efficient is low, cost is high with the modifying plastics material.

The purpose of utility model: the purpose of this utility model provides a kind of Infusion bottle lid, is made up of plastics inner cap, butyl rubber pad, plastic outer cover.Chucking back welding in the centring ring of plastics inner cap lower end and the infusion plastic bottle bottleneck, the quality of liquid in the assurance bottle.The ultra-thin body planar design is adopted in plastic outer cover upper end, and is rational in infrastructure, easy to use, do not use modified materials, and cost is low, can adopt modern high-efficiency appliance production, make easy, production efficiency is high.

Technical scheme: a kind of Infusion bottle lid, form by plastics inner cap, butyl rubber pad, plastic outer cover.It is characterized in that: plastic outer cover centre (1) is the planar ultra-thin body, and plastics inner cap lower end is provided with centring ring (15) and plastics spout chucking (23), and plastics inner cap (13), plastics inner cap (9) exchange combination with plastic outer cover (2).

Beneficial effect: this utility model adopts nonpoisonous and tasteless plastic raw materials to make, and can mate with the infusion plastic bottle of carrying liquid, and plastics inner cap lower end is provided with chucking back welding in a centring ring and the infusion plastic bottle bottleneck, the quality of liquid in the assurance bottle.The plastic outer cover centre is that ultra-thin body adopts planar design, and whether rational in infrastructure, the convenient use or not modified materials, and cost is low, can adopt modern high-efficiency appliance production, make easy, production efficiency is high.
