DEFINITION

Classification: 493/52

Rigid container, (e.g., box, carton, cup, cap, etc.):

(under subclass 51) Method or apparatus including making a receptacle that is intended to generally retain its shape during use.

(1) Note. A small container made of heavy paper may be a rigid container while a large container made of the same heavy paper is pliable. It is the intent of the construction that determines placement of a patent in this subclass.

(2) Note. In order to avoid unnecessary splitting of similar art, it has been determined to consider any envelope or folder as a "pliable container" even if the wall portions are rigid, e.g., a photograph record envelope.
