Definitions
- the present invention relates to the sealing art and more particularly to a method and machine for sealing closure caps to glass containers.
- the invention is an improvement upon the machine and method described and claimed in United States Letters Patent No. 3,054,234 owned by the assignee of the present application.
- the preferred embodiment of the invention is primarily for the application of closures which are applied to containers by a rotary or twisting action. Certain features of the invention are also applicable to machines for the application of so-called press-on closures in which the closures are applied by downward pressure.
- screw caps is used generically herein and is intended to include the usual continuous thread caps, in which a full turn or more is required to seal, and the divided thread or lug caps which may be sealed by a quarter turn.

(Cl. 53-38) The present invention relates to the sealing art and more particularly to a method and machine for sealing closure caps to glass containers. The invention is an improvement upon the machine and method described and claimed in United States Letters Patent No. 3,054,234 owned by the assignee of the present application.
The preferred embodiment of the invention is primarily for the application of closures which are applied to containers by a rotary or twisting action. Certain features of the invention are also applicable to machines for the application of so-called press-on closures in which the closures are applied by downward pressure.
The term, screw caps, is used generically herein and is intended to include the usual continuous thread caps, in which a full turn or more is required to seal, and the divided thread or lug caps which may be sealed by a quarter turn. The latter are sometimes called lug caps, divided thread caps, and twist caps. As indicated above, screw cap, as used herein, is intended to include the group.
The present invention aims to provide an improved sealing mechanism in which screw caps are more evenly applied with a more uniform torque to provide removal without undue efiort on the part of the housewife and at the same time to securely seal the product for safekeeping until it is opened for use.
