SECTION I - CLASS DEFINITION

This is the residual class for receptacles comprised of a peripheral wall made of flaccid or flexible material, with at least one closed end, and having an access opening, which may be an open end of the receptacle or which may be provided in the peripheral wall or closed end of the receptacle. Receptacles of this class type must function, by disclosure, to hold contents which in turn are to be eventually removed from the receptacle.

(1) Note. The peripheral wall is the surrounding external boundary of the bag which, together with a closed end, forms a structure intended to confine or hold contents.
(2) Note. An access opening must be intended to permit insertion of removal of bag content, and may be closed or closable.
(3) Note. A blank intended to be made into a bag of this class type is classified with the bag. A blank is defined as a piece of stock material cut into final shape prior to being folded and secured in usable bag form.
(4) Note. The flaccid or flexible bag material may be strengthened or reinforced to prevent tearing, or to aid in maintaining the bag in a given configuration.
(5) Note. Patents issued before 1900 have been placed hereunder by total disclosure. SCOPE OF THE CLASS This class admits all bags not provided for elsewhere which satisfy the general statement in the Class Definition above.

RELATION TO RECEPTACLE CLASSES

See References to Other Classes, below, for related receptacle classes.

RELATION TO SUPPORT CLASSES:

In general, as between the receptacle classes and the support classes, the receptacle classes provide for the combination of a receptacle plus support; except, the support classes will accept a claim to a support combined with a receptacle, wherein the claim (1) nominally recites the receptacles, or (2) recites only so much of the receptacle structure as is needed to cooperate with the support, or (3) recites only those receptacle features which have been modified specifically to cooperate with the support. See related support classes in the References to Other Classes, below.

RELATION TO HEAT TRANSFER CLASSES:

(A) Related Classes. See References to Other Classes, for related heat transfer classes

(B) Bag Feature Summary "Common" hot water or ice bag, whose contents are intended to be removed before the bag is reused. Class 383, Flexible Bags. See References to Other Classes, for related heat transfer classes with bag feature.
