Embodiment 1

[0068] Next, the process of forming the liquid injection hole 6c in the above-mentioned eye infusion container using the container manufacturing apparatus of the present invention will be described (see FIG. 3 ).

[0069] The thermoplastic material used as the constituent material of the container main body A includes polyethylene, polyethylene-polypropylene, polypropylene, polyethylene terephthalate, polycarbonate, and the like. In this example, the container main body A formed of polyethylene is shown.

[0070] In the container body manufacturing section described above, the container body A is manufactured by blow molding or vacuum molding. Blow molding or vacuum forming can be performed by common methods. In addition, the molded container body A is transported to the molding unit by the transport supply unit.

[0071] In the molding section, the liquid injection port 6a is molded on the container main body A using a liquid injection port forming mechanism (refer to figu...

Abstract

A container manufacturing device capable of manufacturing a container body of a thermoplastic material having a liquid storage part storing chemical liquid and a liquid filling hole for controlling the dropping amount of the outflow chemical liquid to a set amount, comprising a drilling means (X) forming the liquid filling hole through the container body. The drilling means (X) further comprises a needle-like part (10) forming the liquid filling hole through the container body and a PTC heater (11) heating the needle-like part (10).

Description

technical field [0001] The present invention relates to a container manufacturing apparatus provided with a piercing mechanism for penetrating and forming the liquid injection hole when manufacturing a container body made of thermoplastic material having a liquid storage portion and a liquid injection hole for storing liquid, so that The liquid injection hole is used to control the droplet volume of the outflowing liquid to a set volume. Background technique [0002] In medical eye drops, it is necessary to control the instillation amount to a certain amount. In order to achieve this control, an eye drop container equipped with an inner plug member formed with a liquid injection hole is widely used. [0003] In addition, an integral type eye infusion container in which a container main body and a liquid injection cylinder part are integrally formed without using such an inner plug member is also known. [0004] In this one-piece eye drop container, a thermoplastic material ...
