[0004] 2. Description of the Related Art
[0005] A conventional blister pack for product packaging and
display typically has a clear plastic container with a flat
insertion portion held between two flat sheets of materials and a
chamber portion protruding from a cut in one of the flat sheets for
holding the product being sold or displayed. The flat sheets may be
made of corrugated cardboard, SBS board or other suitable
materials, and at least one sheet provides structural support for
the display pack. The flat sheets are of a size that makes the
package suitable for store display. The product may be removed by
separating the two flat sheets or by cutting open the flat sheet or
the plastic container. This type of blister pack is typically not
re-closable once the product is removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Embodiments of the present invention are described with
references to the drawings. FIGS. 1a-1c illustrate a first
embodiment, FIGS. 2a-2c illustrate a second embodiment, FIGS. 3a-3c
illustrate a third embodiment, and FIG. 4 illustrates a fourth
embodiment.
[0022] As shown in FIGS. 1a and 1b, a display pack 10 according to
the first embodiment includes a bottom flat sheet 12, a top flat
sheet 14, and a container 16. The top and bottom flat sheets 14 and
12 are shown in FIGS. 1a and 1b as being made of one sheet folded
over (at a fold 14b), but they may also be two separate sheets. The
flat sheets 12, 14 are preferably both made of a corrugated
cardboard due to its low cost, but may also be made of other
materials such as SBS board, plastic, etc. The two sheets may be
made of the same or different materials. In the assembled pack, the
top and bottom flat sheets 12 and 14 are joined together by
appropriate means depending on the materials used for the sheets.
When both flat sheets are cardboard, an adhesive 18a applied at one
or more edges of the sheets is preferred to join the two
sheets.
[0023] The container 16 is preferably made of a transparent
material such as clear plastic, and preferably PET. As shown in
FIGS. 1b (cross-sectional view of an assembled display pack) and 1c
(top plan view of the container), the container 16 has a chamber
portion 16b where the product is housed and a flat portion 16a
around the chamber portion. In the assembled pack, a part of the
flat portion 16c (the shaded area in FIG. 1c) is inserted between
the top and bottom flat sheets 14 and 12, and the rest of container
16 is exposed by a cutout area 14a on the top flat sheet 14 and
protrudes from the cutout area. The inserted portion 16c may be
attached to the top sheet 14 and/or bottom sheet 12 by appropriate
means so that it does not fall out when the container is open. In
the example shown in FIG. 1b and 1c, the inserted portion 16c
defines a cutout area 16g, and an adhesive 18b is applied between
the top and bottom flat sheets 14 and 12 in the area corresponding
to the cutout 16g to adhere the two flat sheets together and to
retain the inserted portion 16c between the flat sheets. Other
methods may also be used, such as applying an adhesive directly to
the inserted portion 16c to adhere it to the top and/or bottom flat
sheet. Alternatively, the inserted portion 16c may be unattached to
the top and bottom sheets 14, 12 so that it can be removed and
reinserted into the space between the two sheets. A design where
the plastic inserted portions is not adhered to the flat sheets may
be more preferred as being more environmentally friendly as it
allows the plastic and cardboard pieces to be readily separated and
recycled. A crease 16d may be pre-formed along the boundary line
between the inserted portion 16c and the exposed portion of the
container 16, so that the exposed portion can pivot around the
crease while the inserted portion 16c is held by the flat sheets 12
and 14. This opens the container and provides access to the product
housed in the chamber portion 16b. Alternatively (although less
preferred), the crease may be formed in the exposed portion of the
container 16 along a line 16e spaced apart from the boundary line
16d between the inserted portion and the exposed portion.
Alternatively, a crease is not pre-formed in a new package, but may
be formed by the opening of the package.
[0024] Note that although in FIGS. 1a and 1b an end of the chamber
portion 16b abuts an edge of the cutout 14a, which makes the crease
coincide with the end of the chamber portion 16b and the edge of
the cutout 14a, this arrangement is not essential and the chamber
portion 16b may be located away from the edge of the cutout 14a (as
shown in FIG. 1c). More than one chamber portion may be formed on
the container 16. In addition, the bottom sheet 12 may also have a
cut and another container may be inserted between the two flat
sheets and protrudes from the cut on the bottom sheet.
[0025] The container 16 further includes a protrusion 16f, which
fits within a corresponding cutout 12a in the bottom flat sheet 12
to function as a re-closable locking structure for keeping the
container chamber 16b closed. The protrusion 16f and the cutout 12a
are appropriately shaped and sized so that they can be engaged to
close the chamber 16b and can be disengaged by pulling the plastic
piece 16 (the flat portion 16a) or by pushing the protrusion 16f
from the bottom. A plurality of protrusions and corresponding
cutouts may be provided at various locations. The re-closable
locking structure can be used to re-close the clamshell display
pack.
[0026] As shown in FIGS. 2a and 2b, a display pack 20 according to
the second embodiment includes a bottom flat sheet 22, a top flat
sheet 24, a container 26, and a locking insert 28. The top and
bottom flat sheets 24 and 22 are shown in FIGS. 2a and 2b as being
made of one sheet folded over (at a fold 24c), but they may also be
two separate sheets. The flat sheets 22, 24 are preferably both
made of a corrugated cardboard due to its low cost, but may also be
made of other materials such as SBS board, plastic, etc. The two
sheets may be made of the same or different materials. In the
assembled pack, the top and bottom flat sheets are joined together
by appropriate means depending on the materials used for the
sheets. When both flat sheets are cardboard, an adhesive 28 applied
at one or more edges of the sheets is preferred to seal the two
sheets.
[0027] The container 26 is preferably made of a transparent
material such as clear plastic, and preferably PET. As shown in
FIGS. 2b (cross-sectional view of an assembled display pack) and 2c
(top plan view of the container), the container 26 has a chamber
portion 26b where the product is housed and a flat portion 26a
around the chamber portion. In the assembled pack, a part of the
flat portion 26c (the shaded are in FIG. 2c) is inserted through a
slit 24a on the top flat sheet 24 into the space between the top
and bottom flat sheets 24 and 22, and the rest of container 26 is
exposed above the top flat sheet 24. The inserted portion 26c may
be attached to the top sheet 24 and/or bottom sheet 22 by
appropriate means so that it does not fall out when the container
is open. One way to retain the inserted portion (not shown in FIGS.
2b and 2c) is by using a cutout area in the inserted portion 26c,
similar to the structure shown in FIGS. 1b and 1c. Alternatively,
the inserted portion 26c may be unattached to the top and bottom
sheets 24, 22 so that it can be removed and reinserted into the
space between the two sheets. A crease 26d may be pre-formed along
the boundary line between the inserted portion 26c and the exposed
portion of the container 26 so that the exposed portion can pivot
around the crease while the inserted portion 26c is held by the
flat sheets 22 and 24. This opens the container and provides access
to the product housed in the chamber portion 26b. Alternatively
(although less preferred), the crease may be formed in the exposed
portion of the container 26 along a line 26e spaced apart from the
boundary line 26d between the inserted portion and the exposed
portion. Alternatively, a crease is not pre-formed in a new
package, but may be formed by the opening of the package.
[0028] Note that although in FIGS. 2a and 2b an end of the chamber
portion 26b abuts the slit 24a on the top sheet 24, which makes the
crease coincide with the end of the chamber portion 26b and the
slit 24a, this arrangement is not essential and the chamber portion
26b may be located away from the slit 24a (as shown in FIG. 2c).
More than one chamber portion may be formed on the container 26. In
addition, the bottom sheet 22 may also have a cut and another
container may be inserted between the two flat sheets and protrudes
from the cut on the bottom sheet.
[0029] The container 26 further includes a female locking member
26f, which receives a male locking member 28b of the locking insert
28 to function as a re-closable locking structure for keeping the
container chamber 26b closed. The locking insert 28, which is
preferably made of plastic, has a flat part 28a held between the
top and bottom flat sheets 24, 22 and a protrusion (the male
locking member) 28b protruding from a cutout 24b on the top flat
sheet 24 toward the container 26. The female locking member 26f and
the male locking member 28b are appropriately shaped and sized so
that they can be engaged to close the chamber 26b and can be
disengaged by pulling the plastic piece 26 (the flat portion 26a).
The re-closable locking structure can be used to re-close the
clamshell display pack. Alternatively, the female and male locking
members 26f and 28b may be reversed, i.e., the container 26 may
have a male locking member and the locking insert 28 may have a
female locking member which protrudes downwardly from a cutout on
the bottom flat sheet 22. A plurality of pairs of locking members
may be provided at various locations.
[0030] As shown in FIGS. 3a-3c, a display pack 30 according to the
third embodiment includes a bottom flat sheet 32, a top flat sheet
34, and a container 36. The top and bottom flat sheets 34 and 32
are shown in FIG. 3a as being made of one sheet folded over, but
they may also be two separate sheets. The flat sheets 32, 34 are
preferably both made of a corrugated cardboard due to its low cost,
but may also be made of other materials such as SBS board, plastic,
etc. The two sheets may be made of the same or different materials.
In the assembled pack, the top and bottom flat sheets are joined
together by appropriate means depending on the materials used for
the sheets. When both flat sheets are cardboard, an adhesive
applied at one or more edges of the sheets is preferred to seal the
two sheets. The top sheet 34 has a cutout area 34a for exposing a
portion of the container 36 as described later.
[0031] The container 36 is preferably made of a transparent
material such as clear plastic, and preferably PET. As shown in
FIGS. 3b and 3c, the container 36 has a flat insertion portion 36c,
a low wall 36a joined to the flat insertion portion 36c and
protruding from the cutout 34a, and a chamber portion 36b. The area
enclosed by the wall 36a may be open, or it may have a cover sheet
on the same plane as the flat insertion portion 36c. The chamber
portion 36b has a bottom opening that corresponds in size and shape
to the wall 36a so that the chamber portion 36b fits securely
around the wall when the container 36 is closed (see FIG. 3c). When
the container 36 is closed, the chamber portion 36b may be locked
to the wall 36a by means of the tight fit between the contact
surfaces of the two pieces. Alternatively (not shown), re-closable
locking structures such as protrusions and corresponding
indentations, grooves, etc. may be provided on the chamber portion
36b and the wall 36a to lock the two together. Those skilled in the
relevant art will readily appreciate that many such locking
structures may be used to lock two plastic pieces together. The
chamber portion 36b is joined to the wall 36a by a hinge portion
36d and can pivot about the hinge portion to open and close the
container 36 (see FIGS. 3b and FIG. 3c). The product being packaged
is housed in the closed container.
[0032] In the assembled pack, a part or all of the flat insertion
portion 36c is inserted into the space between the top and bottom
flat sheets 32 and 34, and the rest of container 36 is exposed
through the cutout area 34a of the top flat sheet 34. The inserted
portion 36c may be attached to the top sheet 32 and/or bottom sheet
34 by an adhesive, or unattached to them. As shown in FIG. 4, a
display pack 40 according to the fourth embodiment is similar to
the third embodiment show in FIG. 3a. It t includes a bottom flat
sheet 42, a top flat sheet 44, and a container 46. The bottom and
top flat sheets 42 and 44 are similar to the bottom and top flat
sheets 32 and 34 shown in FIG. 3 and their descriptions are not
repeated here.
[0033] The container 46 is preferably made of a transparent
material such as clear plastic, and preferably PET. Similar to the
container 36 in FIG. 3a, the container 46 has a flat insertion
portion (not visible in FIG. 4) which is disposed between the top
and bottom flat sheets 44 and 42 in the assembled pack. A raised
base portion 46a is joined to the flat insertion portion and
protrudes from a cutout area 44a of the top sheet 44. The container
46 further includes a chamber portion 46b connected to the raised
base portion 46a by a hinge portion 46d to open and close the
container. A peripheral portion 46e of the chamber portion has a
size and shape corresponding to the size and shape of the raised
base portion 46a so that the chamber portion fits securely around
the raised base portion 46a when the container 46 is closed. A
central portion 46f of the chamber portion forms a chamber to house
the product being packaged. When the container 46 is closed, the
chamber portion 46b may be locked to the raised base portion 46a by
means of the tight fit between the contact surfaces of the two
pieces. Alternatively (not shown), re-closable locking structures
such as protrusions and corresponding indentations, grooves, etc.
may be provided on the chamber portion 46b and the raised base
portion 46a to lock the two together. Those skilled in the relevant
art will readily appreciate that many such locking structures may
be used to lock two plastic pieces together.
[0034] In the embodiments shown in the drawings, the bottom flat
sheet (12, 22, 32, 42) is shown as being substantially a solid
sheet. Alternatively (not shown), the bottom sheet may have a
cutout area with a second plastic container protruding therefrom as
in a conventional blister package. In particular, in the first,
third and fourth embodiment, a cutout on the bottom sheet and a
second container may be provided that correspond in location to the
container on the top (16b, 36b and 46b), so that the top and bottom
sides of the product may be visible. The second container at the
bottom need not be re-closable.
[0035] More generally, a display pack according to embodiments of
the present invention includes a support base formed of a top and a
bottom flat sheet (14, 24, 34, 44 and 12, 22, 32, 42) joined
together, and a re-closable container (16, 26, 36, 46) that
includes a fixed portion (16c, 26c, 36c and 36a, 46a) retained by
the support base and a moveable portion (16a and 16b, 26a and 26b,
36b, 46b) joined to the fixed portion. The fixed portion includes a
flat insertion portion (16c, 26c, 36c) inserted into a space
between the top and bottom flat sheets. Alternatively, although
less preferred, the fixed portion may include a flat portion that
is attached to an outer surface of the top sheet by an adhesive or
other suitable means. The moveable portion can bend or pivot with
respect to the fixed portion to open and close the container. A
re-closeable locking structure is provided to lock the moveable
portion to either the support base (first and second embodiments
shown in FIGS. 1a-1c and 2a-2c) or to the fixed portion of the
container (third and fourth embodiments shown in FIGS. 3a-3c and
FIG. 4) when the container is closed. The support base or the fixed
portion of the container includes a first part of the re-closable
locking structure, and the moveable portion includes a second part
of the re-closable locking structure which engages with the first
part of the re-closable locking structure to lock the container. In
the third and fourth embodiments shown in FIGS. 3a-3c and FIG. 4,
the wall 36a or the raised base portion 46a is a protruding portion
that constitutes the first part of the re-closable locking
structure, and the bottom part of the chamber portion 36b
constitutes the second part thereof. Alternatively, if protrusions
and indentations are provided on the wall 36a or raised base
portion 46a and the bottom part of the chamber portion 36b or the
peripheral portion 46e that contacts each other, such protrusions
and indentations constitute the re-closable locking structure.
[0036] When corrugated cardboard is used as the top and/or bottom
flat sheet, a technique may be applied to press the cardboard in
the edge area to crush the corrugation in the board. This technique
is described in more detail in commonly owned provisional patent
application U.S. 60/717,024, filed Aug. 24, 2005 (priority from
this provisional application was claimed in U.S. patent application
Ser. No. 11/374,769, file Mar. 14, 2006 and PCT application No.
PCT/US 06/32274, filed Aug. 18, 2006). Crushing may be either used
in conjunction with a heat sensitive adhesive to seal the top and
bottom sheets, or used solely to crush the edge of the display pack
to improve its aesthetic appearance and make it less easy to tear
open.
[0037] An advantage of display packs according to embodiments of
the present invention over conventional re-closable clamshell packs
is that the top and bottom flat sheets can be made of non-plastic
materials, such as cardboard in particular. This significantly
reduces the amount of plastic used. Cardboard is less expensive and
more environmentally friendly as it uses more post-consumer
recycled material than some other board material.
[0038] It will be apparent to those skilled in the art that various
modification and variations can be made in the display packs of the
present invention without departing from the spirit or scope of the
invention. Thus, it is intended that the present invention cover
modifications and variations that come within the scope of the
appended claims and their equivalents.
