Inverse blow-fill-seal packaging
A method for blow-fill-seal (BFS) packaging of a product and a BFS package. The method forms a BFS package with a twist-off top, container body and information panel in a main mold. The container is filled via a fill opening located distal to the twist-off top and the fill opening is sealed with a base portion. This provides a container having a twist-off top that is more reliably secured to the container body. A plurality of containers may be attached to a single information panel. The BFS packaging system may employ a quick change insert to reduce lost production time when changing products or lots. The package includes an information panel integrally formed with a plurality of twist-off tops, each of which is removably attached to a container body whereby each container body can be removed from the package without removing the remaining container bodies from the information panel.
1. A method of forming and filling a blow-fill-seal package comprising the steps of:
(a) molding a single information panel, a plurality of container bodies and a plurality of twist-off tops of a blow-fill-seal package in a manner whereby each twist-off top is integrally formed with the information panel and each twist-off top is attached to one said container body in a manner whereby the container body can be removed from the integrally formed twist-off and information panel top by twisting the container body relative to the twist-off top;
(b) filling each container body from step (a) via an opening in the container body; and
(c) after step (b), sealing the opening in the container body with a base portion,
wherein the blow-fill-seal package is molded such that the twist-off top remains connected to the information panel upon removal of the container body from the blow-fill-seal package.
2. The method of claim 1 , wherein the opening in the container body is distal to a location of the twist-off top.
3. The method of claim 1 , wherein information is molded into the information panel in said molding step using a mold insert.
4. The method of claim 1 , wherein in the molding step at least one of a name, dosage, administration instructions and expiration date for product located in said container bodies are provided to the information panel.
5. The method of claim 1 , wherein molding the information panel, container body and the twist-off top is carried out in a main mold.
6. The method of claim 5 , further comprising the step of forming the base portion in a sealing mold.
7. The method of claim 1 , wherein the information panel comprises lot and expiration data for product located in said container bodies.
8. The method of claim 7 , wherein the information panel further comprises dosage data for product located in said container bodies.
