A temperature adjustment mold capable of performing local temperature adjustment in an axial direction from the inside of a preform while restricting shrinkage and deformation of the preform, for adjusting a temperature of an injection-molded bottomed resin-made preform includes a rod portion inserted into the preform and extending in the axial direction of the preform. The rod portion includes an annular projection portion that protrudes in a radial direction of the rod portion and contacts an inner peripheral surface of the preform. The rod portion contacts a bottom portion of the preform to restrict shrinkage in the axial direction of the preform. The projection portion restricts shrinkage in a radial direction of the preform, conducts heat between the rod portion and the preform, and adjusts a temperature at a predetermined part in an axial direction of the preform.

Temperature adjustment mold and apparatus and method for producing resin container

The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

Resin container manufacturing method

A resin container coating device of the present invention includes a plurality of chambers storing a plurality of resin containers respectively in independent states, a plurality of internal electrodes in which gas conductive parts for conducting a source gas are formed to inner peripheral parts thereof and which are respectively inserted inside the plurality of resin containers stored in the chambers, a gas supply unit for supplying the source gas to the plurality of chambers, a high frequency power source for supplying a high frequency electric power to the plurality of chambers, and an electric power switching part capable of switching a supply designation of the high frequency electric power, which is supplied from the high frequency power source, from first and second chambers forming a first unit to third and fourth chambers forming a second unit.

Resin container coating device

An object of the invention is to provide a coating apparatus for a resin container capable of improving mass-production efficiency of coating-treated resin containers. A plurality of container holding members, which are installed on a rotating table and can hold a resin container, are sequentially moved to a container supply position in which the resin container is supplied, a coating treatment position in which coating treatment of forming a thin film on an inner surface of the resin container is performed in a state of being combined with a chamber lid part, and a container detachment position in which the resin container to which the thin film is formed by the coating treatment can be detached according to the rotation of the rotating table, so that the treatments in the respective positions are performed in parallel.

Coating apparatus for resin container, and resin container manufacturing system

A gas barrier synthetic resin containerhas an opening portiondefined by a flangeA, a body portionhaving the opening portion, and a bottom portionfor closing the end of the body portion. The containeris a wide mouth container having the minimum inside diameter Dmin of the opening portionlarger than the maximum inside diameter Dmax of the body portion. Alternatively, the containermay be a wide mouth container having the minimum inside diameter Dmin of the opening portionsmaller than the maximum inside diameter Dmax of the body portion, the difference between the diameters being equal to or less than 20 mm. A diamond-like carbon filmis formed on an outer wall of the body portionand bottom portionof the container. After the containerhas been filled with contents, a metal coverand the flangeA are double-seamed onto the container to provide improved gas barrier properties to the entire container.
