Abstract
A method and a preform for blow molding to form a plastic container are disclosed, the preform having a coating formed on an inner surface thereof. The coating reduces a loss of heat energy from the heated preform during expansion thereof to ensure the preform maintains a temperature at or above the phase change/solidification temperature of the material forming the preform.
Claims20
A preform for blow molding to form a plastic container comprising:
- a neck portion forming an opening providing fluid communication with an interior of the preform;
- a body portion having a closed end cap, the neck portion and the body portion forming an inner surface;
- and
- a coating formed on the inner surface of the body portion of the preform, the coating having a thermal conductivity less than a thermal conductivity of a material forming the preform.
1 more element
A method of simultaneously forming and filling a container comprising:
- disposing a heated preform having a coating on an inner surface thereof in a mold cavity, the coating having a thermal conductivity less than a thermal conductivity of a material forming the preform;
- delivering a liquid into the preform thereby expanding the preform and the coating toward an interior surface of the mold cavity to form a resulting container, wherein the coating reduces a loss of heat energy from the heated preform during the delivering step;
- and
- wherein the liquid remains within the container as an end product.
1 more element
A method of simultaneously forming and filling a container comprising:
- disposing a heated preform having a sacrificial coating on an inner surface thereof in a mold cavity, the coating having a thermal conductivity less than a thermal conductivity of a material forming the preform;
- delivering a liquid into the preform thereby expanding the preform and the coating toward an interior surface of the mold cavity to form a resulting container, wherein the coating dissolves into the liquid or evaporates to reduce a loss of heat energy from the heated preform during the delivering step to ensure the preform maintains a temperature at or above the phase change/solidification temperature of the material forming the preform;
- and
- wherein the liquid remains within the container as an end product.
