Abstract
Ways for controlling a level of a product in a container are provided that include engaging an exterior surface of the container containing the product at a first product level. A force is applied to the exterior surface of the container to cause the container to change from a first volume to a second volume. Cessation of the force results in the container containing the product at a second product level. The second product level can provide an accurate and reproducible final product level in the container.
Claims18
A process for controlling a level of a product in a container, the process comprising:
- engaging an exterior surface of the container containing the product at a first product level;
- and
- applying a force to the exterior surface of the container to cause the container to change from a first volume to a second volume, wherein the first volume is less than the second volume;
- whereupon cessation of the force results in the container containing the product at a second product level, and wherein the container remains at the second volume following cessation of the force.
A process for controlling a level of a product in a container, the process comprising:
- engaging a projection on an exterior surface of the container containing the product at a first product level, the projection resulting from one of a sprue in forming the container or from extrusion blow molding of the container;
- and
- applying a force to the projection to cause the container to change from a first volume to a second volume, wherein the first volume is less than the second volume;
- whereupon cessation of the force results in the container containing the product at a second product level.
