ABSTRACT OF THE DISCLOSURE
A pad of plastic bag units comprising a plurality of
bag pockets overlying each other in layers, each pocket
having an open mouth and an extension of its rear wall, there
being a score line in the extension defining the edge of
the rear wall of the bag when the bag is severed from the
pad. The extensions of all the pockets being secured
together to form a base portion for the pad, and welds or
similar connections at the side of the base portion which
form side anchors to provide a counterforce when a forward
pull is exerted at the mouth of an individual pocket, whereby
the bag is completely opened simultaneously with its being
severed from the pad, and a handle constituted by a slit or
similar device in the base portion to permit entry of the
fingers of a hand or any other desired support means which
will act to support the pad while an individual has is
severed therefrom.

SPECIFICA'rION
~ his invention relates to plastic bags, and it
partlcularly relates to packs or pads comprising a plurality
of plastic bags connected to each other in such a manner
that the pad may be easily supported by hand or by any other
desired support means while individual bags are removed
as desired.
~ he pads of the present invention comprise layers of
individual plastic bags which are easily adaptable to be
held in the hand while severing individual bags, thereby
making it highly portable and available at any time. However,
these pads may also be used on any feasible type of fixed
support, if so desired.
It is, therefore, an object of the present invention to
provide self-contained pads of plastic bags which are adapted
to be used either while held in the hand or on a fixed
support~
It is another object of the present invention to provide
pads of bags of the aforesaid type which permit full opening
of the individual bags by the simple motion of tearing them
away from the pad.
Another object of the present invention is to provide
pads of bags of the aforesaid type which are simple in
construction and inexpensive to produce.
Other objects and many of the attendant advantages of
this invention will be readily appreciated as the same becomes
better understood by reference to the following description
when read in conjunction with the accompanying drawings
wherein:
Fig~ 1 is a front perspective view of a pad of bags em-
bodying the present invention.

~ D~
Fig. 2 is a front perspective view showing the pad of
bags of Fig. 1 held in one hand while pulling a bag away
with the fingers of the other hand.
Fig. 3 is a partial perspective view, partly broken
away, showing the pad of bags of Fig. 1 mounted on a fixed
support.
Referring now in greater detail to the various figures
of the drawing wherein similar reference characters refer
to similar parts, there is shown a pad, generally designated
10, comprising a series of plastic bag pockets 12. Each
pocket 12 has an open mouth 14 defined at its front by a
free edge 16 forming the upper edge of the front wall of
the pocket - which becomes a bag when separated from the pad.
The rear wall of the pocket extends beyond the edge 16 of
the front wall and has an upper edge 18. A score line 20
extends from edge to edge of the extending portion of the
rear wall and defines the upper edge of the rear wall of
the bag after it is torn away from the pad.
The portion of the rear walL extending beyond the score
line constitutes an extension or selvage portion 22. When
the individual bag pockets are placed in o~erlying layered
arrangement, as shown in Fig. 1 of the drawing, their over-
lying extensions are integrally connected, as, for example,
by one or more end welds 26 and by side welds 28. These
welds form a solid connection between the layered extensions,
which thereby form a base portion for the pad. Although
these welds are preferably used, it is possible to substitute
other integrating or connecting means such as clips, staples,
adhesive, or the like.
The base portion 24 is provided with an elongated slit 30,
which may be used as a handle or grasping means, the latter

'7aJ
term being used to include not only a handle which may be
grasped by the hand but also something which may be grasped
by a device forming part of a fixed support or any other
mechanical means, such as,for example, shown in Fig. 3.
~ he slit is shown in use in Fig. 2 where the pad is held
in the palm of the hand 32, with one or more fingers 3~
extending through the slit. While being held in this manner,
one or more fingers 36 of the other hand are inserted into
the mouth 14 and the front wall of the pocket is pulled
forwardly. The side welds 28 resist this forward pull,
thereby causing the front wall to pull completely away from
the rear wall; this causes the pocket to open completely at
the same time it is being se~ered ~rom the pad to form a bag.
Fig. 3 illustrates the pad 10 mounted on a fixed support,
generally designated 38, comprising a bed 40 having an
upstanding lug 42. The pad is mounted on the support 38 by
laying it flat on the bed ~0 and inserting the lug 42 through
the slit 30.
Although one particular type of support means is
illustrated in Fig. 3, this is merely for exemplification
and any other desirable support means may be substituted.
It is, Eurther, to be understood that although an elongated
slit 30 is illustrated as one form of grasping means, and
although such slit is preferable, any other feasible and
desirable means may be substituted. For example, a plurality
of smaller slits may be used, or the slit or slits may extend
only partially through the base portion rather than entirely
through it, or, instead of slits, one or more holes may be
bored through the base portion. Such holes could be of
dimensions that could accommodate the finger or fingers of a
person's hand or the pins, lugs, hooks, or the like, of a

55~
fixed support. Or upstanding pins, lugs, knobs, or the like
may be used instead of slits or holes.
In all instances, however, the slit or any of the other
grasping means would be positioned in the base portion formed
by the extensions 22 and would, therefore, have no effect on
the construction or use of the bags when they are separated
from the pad.
As indicated above, it is within the scope of the present
invention to substitute clips, staples, adhesives, etc. for
the preferable welds specifically shown at 26 and 28. When
welds are used, it is preferable to use edge-type welds such
as shown at 26 and 28, but other types of welds, such as
the plug-type, may be substituted or used in addition to the
edge-type welds if so desired.
The score line 20 is shown as consisting of a series of
linearly arranged slits and land portions or "nips". The
nips are the connecting means holding the pocket to the pad.
Although the score line 20 preferably consists of a plurality
of slits and nips, as shown, it is possible, within the
scope of the invention, to provide an elongated slit with
only one nip holding the parts together. The term "score line",
as used herein, is applicable to either type.
