Abstract
An apparatus and method of delivering a predetermined volume of a liquid product, defined as the liquid end product, formed by addition of a first and second liquid product, into a thermoplastic container formed from a heated preform positioned in a mold and having an opening opposite an injection head. Prior to injecting the second liquid product into the preform causing expansion of the container, the preform is at least partially, filled with the first liquid product.
Claims18
A method of delivering a predetermined volume of a liquid end product into a thermoplastic container, the method comprising the steps of:
- forming the liquid end product by addition of a first liquid product and second liquid product;
- forming a thermoplastic container from a heated preform positioned in a mold and having an opening opposite an injection head;
- injecting the second liquid product into the preform and causing expansion of the container;
- and
- introducing the first liquid into the preform before injecting of the second liquid product, all of the first liquid being introduced into the preform before expanding of the preform in the mold cavity.
A method of delivering a predetermined volume of a liquid end product into a thermoplastic container, the method comprising the steps of:
- heating a preform;
- transferring the preform into a mold;
- at least partially filling the preform with a first liquid product, all of the first liquid product being filled into the preform without causing expansion of the preform;
- axially stretching the preform;
- injecting a second liquid product into the preform causing expansion of the preform and forming of the thermoplastic container;
- forming the liquid end product by addition of the first liquid product and the second liquid product;
- and
- wherein the step of at least partially filling the preform with the first liquid product is performed prior to the injecting of the second liquid product.
