DEFINITION

Classification: 493/93

Liner:

(under subclass 84) Method or apparatus wherein one of the workpieces comprises a member intended to extend about the inside of the receptacle to restrict engagement of the contents of the receptacle from the inner surface of the receptacle.

(1) Note. The inner member of this subclass may cover the entire or less surface of the receptacle; however, it is not self-sufficient to hold the contents without the receptacle.

(2) Note. Included herein is assembling a preformed container and a preformed liner, even without additional "container making".

(3) Note. Manipulation of a container having a liner, e.g., closing the flaps, is not considered to be assembling of the liner and the container for this and the indented subclasses.

309+, for opening the end of a liner for assembly with the end of a rigid container without placing the liner inside the container.
