DISPLAY PACKAGES
Abstract
A pair of juxtaposed identically constructed transparent box
members are positioned at opposite sides of a display card which is
formed with an opening in register with the box members, so that
the latter coact to define a closed compartment. The box members
are provided with pairs of flanges which have the card sandwiched
between them, and detents passing through the card locking the
flanges together, thus holding the box members and the card in
assembled relation. The locked flanges are intended to be broken
off the box members so that the latter may be separated for gaining
access to contents of the compartment. The box members may be used
again to hold the contents.

Description
This invention relates to new and useful improvements in display
packages, and in particular the invention concerns itself with
improvements in so-called "bubble" or "blister" packages in which
merchandise is contained in a transparent plastic bubble or blister
mounted on a display card, the latter being capable of being
suspended, for example, from a hook on a display rack.
Conventional packages of this type require the card to be coated
with plastic in order that the plastic bubble or blister may be
heat-sealed thereto. This requires expensive coating and
heat-sealing equipment as well as skilled labor to operate the
same, and even at best, the rate of package production is limited
by the number of heat-sealing stations which are available on the
packaging line. Moreover, the conventional package itself has some
disadvantages, such as that merchandise in a bubble on one side of
the display card cannot be seen from the opposite side, and that
the bubble, once broken for removal of the merchandise, can serve
no further useful purpose.
It is, therefore, the principal object of the invention to provide
an improved display package which eliminates the above outlined
disadvantages of conventional bubble or blister type packages, and
lends itself to easy and rapid assembly without the use of
expensive equipment or skilled labor. As such, the invention
provides a package consisting of a pair of juxtaposed, transparent
box members which are positioned at opposite sides of a display
card in register with an opening formed in the card, so that the
two box members define a closed compartment in which merchandise is
contained for visibility from both sides of the card. The box
members are provided with frangible flanges which have the card
sandwiched between them and the flanges are locked together by
detents which pass through the card and serve to hold the box
members and the display card in assembled relation until such time
as the locked flanges are broken off the box members and the box
members are separated for removal of the merchandise. Although the
invention contemplates the positioning of the box members on a
display card, the box members may also be used themselves as a
merchandise container without a display card.
Other objects, features and advantages of the invention will become
apparent from the following description taken in conjunction with
the accompanying drawings, wherein like characters of reference are
used to designate like parts, and wherein:
FIG. 1 is an isometric view of a display package in accordance with
the invention;
FIG. 2 is an end elevational view thereof;
FIG. 3 is an enlarged isometric view of one of the box members;
FIG. 4 is an enlarged sectional detail taken substantially in the
plane of the line 4--4 in FIG. 1;
FIG. 5 is an enlarged sectional detail taken substantially in the
plane of the line 5--5 in FIG. 1; and
FIG. 6 is an enlarged, fragmentary sectional view showing the
alignment sustaining means of the box members.
Referring now to the accompanying drawings in detail, the display
package of the invention is designated generally by the reference
numeral 10 and, as shown in FIGS. 1 and 2, mainly consists of a
pair of complemental, juxtaposed box members 12 which are
positioned at the opposite sides of a display card 13. The card is
thus sandwiched between the two box members and a portion of the
card in register with the box members is cut out to form an opening
14 (see FIG. 5) so that the box members are in communication
through the card opening and define a closed compartment for
containing merchandise. The display card 13 may be printed with
suitable indicia and may have its upper portion provided with an
aperture 15 for suspension of the entire package from a hook, as
for example, on a display rack or peg board.
The two box members 12 are identical in construction and are formed
from transparent plastic material so that their contents may be
viewed from both sides of the display card 13. Although the box
members are shown as being rectangular, they obviously may have any
other suitable geometrical configuration. In any event, each box
member 12 is formed integrally at its opposite ends with outwardly
projecting flanges 16, 17, the flange 16 of each box member being
provided with laterally projecting, hook-shaped detents 18 for
locking engagement with apertures 19 formed in the flange 17 of the
other box member, as will be presently explained.
The display card 13 is provided adjacent the opening 14 with
apertures or passages 20 through which the detents 18 may extend
from one side of the card to the other. Although the two box
members 12 are of identical construction as aforesaid, they are
applied to the opposite sides of the card 13 in reverse
orientation, that is to say, so that the flange 16 of each box
member is juxtaposed to the flange 17 of the other box member and
the detents 18 on the flanges 16, after passing through the card
apertures 20, are received in the apertures 19 in the flanges 17.
As will be apparent from FIG. 4, the transverse spacing of the two
detents 18 on the flange 16 is such in relation to the spacing of
the apertures 19 in the flange 17 that the hook-shaped ends of the
detents 18 must be deflected in order to pass through the apertures
19, whereupon the hook-shaped ends of the detents spring out into
locking engagement with the flange 17 in the manner of a
snap-fitted assembly. When this has been accomplished the flanges
16, 17 are locked together and serve to sustain the two box members
12 and the card 13 in assembled relation. It is to be particularly
noted that this snap-fitted assembly can be effected without the
use of any special equipment or skilled labor, as is necessary with
conventional blister type packages utilizing a plastic coated
display card and a plastic blister heat-sealed thereto. Also, as
already stated, the transparent box members 12 permit viewing of
the merchandise from both sides of the display card, and this
affords a further advantage in that, assuming the card to be
printed with indicia on both sides, the package may be hung on a
rack with either side facing outwardly.
The flanges 16, 17 have a reduced or a weakened thickness along the
line where they are connected to the box members 12, as shown at
21, thus providing a frangible connection by virtue of which the
flanges, while still locked together by the means 18, 19, may be
broken off the box members 12 and remain attached to the card 13
while the box members 12 are separated from each other and from the
card for removal of the packaged merchandise. The card 13, which
may be of cardboard, is sufficiently flexible to permit breaking
off of the flanges by bending, and inasmuch as the locked together
flanges must be broken off before the package may be opened, the
invention safeguards against pilfering and makes it easy to detect
a package which has been tampered with.
It may be also noted that the detents 18 have cam-surfaced edges
18' for coaction with cam-surfaced edges 19' of the apertures 19,
whereby to assist in insertion of the detents through the
apertures, as will be apparent from FIG. 4.
As shown in FIG. 3, each of the box member 12 is provided at its
diagonally opposite corners with projecting guide elements 22 and
with recesses 23, the arrangement being such that when the two box
members are juxtaposed as already described, the guide elements 22
of each box member are received in the recesses 23 of the other box
member. This arrangement assists in maintaining the two box members
in alignment with each other while they are being applied to the
display card 13 ad is of even greater importance when, after the
flanges 16, 17 have been broken off and the box members are
separated for removal of the merchandise, the two box members may
be placed to further use, without the card 13, by juxtaposing them
as shown in FIG. 6 to provide a container of general utility to
hold the original contents for repeated usage. In such instance the
interfitting guide elements 22 and recesses 23 serve to hold the
box members together in proper alignment.
It may be also noted that although the invention primarily intends
to utilize the two box members 12 in conjunction with the display
card 13 in the environment of a display package of the character
described, it is possible to omit the card 13 and to use the box
members 12 with their associated flanges 16, 17, locking means 18,
19 and alignment means 22, 23, in the environment of a simple
container or package by simply snap-fitting the two parts together
without sandwiching the card 13 therebetween. Such a simple package
may be opened by breaking off the flanges 16, 17, whereupon the two
box members may be used to provide a container of general utility
as already mentioned in connection with FIG. 6.
