the portion of the film above the blister portion, by peeling back or breaking
such portion of
the film, which may or may not be perforated or pre-cut, to expose the
article, or by other
similar means. In one embodiment, the rupturable film sheet 50 is desirably
made of
recyclable material.
In one embodiment, rupturable film sheet 50 is affixed to unitary blister pack
40 by
use of heat sealing, adhesive seals (such as with heat-activated or solvent
adhesive such as
glues), RF or sonic seals, or any other suitable means. The materials of the
rupturable film
sheet 50 and the unitary blister pack 40may be pre-treated to facilitate
sealing of such
materials together.
As shown in Fig. 2, the unitary blister pack 40 is mounted between the front
inner
face 20 of front sheet 10 and the rear inner face 35 of rear sheet 25. As
shown in Fig. 1, rear
sheet 25 contains blister openings 55 that allow the plurality of blister
portions 45 to protrude
through rear outer face 15 of rear sheet 25. In one embodiment, as shown in
Fig. 2, there is a
blister opening for each blister portion. Such arrangement also assists
maintaining the blister
pack 40 mounted between front sheet 10 and rear sheet 25 In another embodiment
(not
shown), multiple blister portions protrude through a single blister opening.
As shown in Fig. 3, front sheet 10 contains an operable flap 60 that allows
access to
the portion of the rupturable film sheet 50 covering the plurality of blister
portions 45. Fig. 3
depicts operable flap 60 in a closed position, covering the portion of the
rupturable film sheet
50 covering the plurality of blister portions 45. Flap 60 may initially be
opened by breaking
flap perforations 61 and folding operable flap 60 along flap crease 62. Fig 4.
depicts operable
flap 60 in an open position, exposing the portion of the rupturable film sheet
50 covering the
plurality of blister portions 45 (such portions depicted within areas 51 in
Fig. 4). By
exposing the rupturable film sheet 50, the user of the package is able to beak
the portion of
the rupturable film sheet 50 covering a blister portion 45 and remove the
article contained
within. The operable flap 60 may then be returned to the closed position
covering the portion
of the rupturable film sheet 50 covering the remainder of blister portions 45
still containing
articles.
The operable flap 60 also provides visibility to a portion of front inner face
20 of the
front sheet 10 when the operable flap 60 is in the open position. In one
embodiment, both the
outer face of the operable flap 60 and the inner face of the operable flap 60
contain writing.
In one embodiment, front sheet 10 contains a single operable flap 60 that
allows

operable flaps 60 each of which allows access to only a portion of the
rupturable film sheet
50 covering only a portion of the plurality of blister portions 45.
In one embodiment, operable flap 60 contains a tab 70 that is operative to
releasably
maintain the operable flap 60 over the portion of the rupturable film sheet 50
covering the
plurality of blister portions 45. In one embodiment, when operable flap 60 is
in the closed
position, tab 70 can come into frictional contact with edges 41 and 42 of rear
sheet 25,
thereby maintaining operable flap 60 in the closed position.
In one embodiment, card 5 comprises one or more sets of perforations 75
between a
removable portion of card that is not in contact with the unitary blister
package and the
portion of the card that is in contact with the unitary blister package. Such
an embodiment
allows for the user once they have purchased the blister card display package
1 to remove a
portion of card 5, thereby reducing the size of the blister card display
package.
In one embodiment, the unitary blister package contains an opening 80 for
hanging
the blister card display package from a support device, such as an extended
peg of a pegboard
display. In one embodiment, a removable portion of the card contains such
opening for
hanging the package from a support device.
