tops which are so closed cannot readily be opened With
out tearing the bag walls. When this occurs, it may be
come di?icult to so close the bag as to assure complete
protection to the contents remaining in the bag body.
The present invention is directed to a bag top closure
which is so constructed that the bag top may readily be
alternately opened and closed a number of times without
danger of the bag top becoming leaky with a possible de- c
ten'oration of the contents of the bag.
A further object is to provide a device of this kind
which is extremely simple and inexpensive to fabricate,
and which may readily be manipulated to open or close
the ‘bag top with a minimum of effort.
A further and more speci?c object of the invention is
to provide a combined carrying device and bag top closure
comprising an elongated rigid member formed from a
blank of sheet material folded upon itself to provide a
pair of longitudinally extending parallel bag top receiv

closed, there is illustrated in FIGURE 1, for purposes of
disclosure7 a container or bag body, generally designated
by the numeral 2. The upper end portions of the walls
of the bag body which cooperate to de?ne the bag mouth,
are ?exible to permit them to be pressed into ?atwise
relation and transversely folded in the initial step of
closing and sealing the bag top.
An important feature of the present invention resides
in the provision of an elongated rigid-like member
adapted to be ?tted over the transversely folded upper

marginal edge portions of the bag top walls to retain
said channels.
A further object of the invention is to provide a carry 40 them in seal-tight relation, when the open bag top is
