Blister pack panel for face powder compact display
Abstract
Blister pack panel for face powder compact display in which the
purchaser checks the color of the face powder to determine the
suitability of that color for the personal preferance of the
purchaser by opening the compact, the blister pack being of a
special novel construction to fit over the latching projection and
around the hinge opposite the latching projection so that the
blister retains the compact securely in tamper proof relation to
the solid supporting panel used to display the case. Heretofore a
pressure sensitive label which was dyed to match the color of the
powder in the compact was affixed to the panel next to the printed
description of the shade of the powder. These dyed pressure
sensitive lables become soiled during handling by the purchasers
and change color. Also the dyed labels may change color because of
exposure to strong lighting as for example in a high intensity spot
light which may be used for a cosmetic display case. This problem
facing the purchaser of finding that color on the card label does
not match the color when the purchase has been made and the
contents inspected is overcome by the present invention because the
transparent blister of special ovoid shape and construction which
is modified specifically for the clasp and hinge parts of the
compact provide a much more economical display of the face powder
compact than displays of the prior art which rely upon pressure
sensitive labels or cut out panel formations.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to special packages for article housing
attached to a panel container consisting of a plate backing member
to which an enclosing cover is affixed, the enclosing cover being
made of a relatively heavy gauge thermoplastic material such as
vinyl resin and being contoured to retain the article in tamper
proof relation to the solid panel.
2. Description of the Prior Art
Blister pack display packages have been described for the inclusion
of tamper proof features such as a folded hinge insert between
hinges of a transparent razor blade display case described in
Snape, U.S. Pat. No. 3,025,958.
Blister pack cosmetic displays have been suggested for the purpose
of permitting the purchaser to check the shade of the cosmetic as
in the lipstick display package of Warner, et al, U.S. Pat. No.
3,762,545. . This lipstick package uses a special container for the
lipstick which permits the lipstick to protrude when the package is
inverted.
Quick opening blister pack packages for cosmetics have been
suggested to facilitate opening the cosmetic package and examples
of quick opening packages are shown in FIGS. 9 through 11 of
Hellstrom, U.S. Pat. No. 3,942,640.
Finally, there are lipstick blister packs in which the package
itself is retained with the goods which are placed into the lady's
purse as in Acker, U.S. Pat. No. 4,326,546.
In none of the cosmetic packages except one which is sold by Noxell
Division under the Trademark COVER GIRL, is there provided a face
powder compact display blister package which is associated with a
backing panel which utilizes shrink wrapping of thin gauge
thermoplastic wrapping material for retaining the compact within
the panel in a cut out portion of the panel against a back
panel.
It is known that artists packages such as in Heberline, et al, U.S.
Pat. No. 571,521, are provided in which cavities are filled with
powders in different colors and these powders are wrapped with
their transparent plastic wrappings. The customer may check these
colors easily and in use may remove the wrapping to select the
color which is viewed directly. However, there is no suggestion in
the prior art that a heavy gauge transparent blister pre-form be
modified for a face powder compact display so that it will cover
the face powder contents only, retaining the compact in cradled
relation to the solid panel and permitting opening and closing of
the compact for purchasers who may wish to check the shade. The
COVER GIRL display is formed of a special cut out 2-ply folded
panel and the process for enrobing the compact is known as Shrink
Pack, a very flexible and thin sheet material being used for
wrapping the compact within the enclosure provided by the cut out
portions of the panel. There are no cut out portions in the "Shrink
Pack" of COVER GIRL.
The present invention distinguishes over the COVER GIRL compact in
utilizing an entirely different and novel pre-form of the blister
for attachment to a solid panel.
SUMMARY OF THE INVENTION
A face powder compact display unit comprises a solid panel, a
pre-formed blister consisting of relatively heavy gauge
thermoplastic material and a face powder compact held within the
blister on the panel by heat sealing the bottom edges of the
pre-formed blister blank to the panel. The invention is based upon
the novel features of the pre-formed blister which adapt it to be
inserted between the mirror of the compact in the top and over the
face powder contents in the bottom of the compact so that the
blister which secured the compact to the panel passes through the
compact between the top and bottom and yet permits the compact to
be opened and closed by its latch and clasp.
The pre-formed thermoplastic blister before sealing the face powder
compact to the panel is generally ovoid in shape and is cut in
critical portions of the blister to completely cover the face
powder chamber or well near the hinge, to completely cover the
indented sides adjacent the lapping projection of the locking clasp
and to center the compact within the blister pre-form prior to heat
sealing so that there is a secure and tight support for the compact
provided by the heat sealed blister.
It is a feature of the blister material in distinction to shrink
wrap materials which have been used heretofore that the
thermoplastic sheet material which is pre-formed be relatively
thick and rigid in contrast to shrink wrap material which is thin,
pliable and flexible. For a 5-gauge vinyl resin blister material
which is conventionally used for blister pack the thickness of the
pre-formed blister varies from 3 to 4 mils. The thickness may be
heavier, e.g. from 5-7 mils. Shrink wrap material varies from 1/2
mil to 1 mil in thickness. The rigid characteristic of the sheet
material is likewise different, e.g. the blister pack is stiff and
can not be stretched or deformed while the shrink pack is thin and
stretches easily and thereby readily deformed. The special blister
pack pre-formed material of the invention has its maximum thickness
at the latching portion where repeated locking and unlocking
operations of the compact can occur. A very substantial thinning of
the blister pack can occur during its deformation while it is being
cut and pre-formed without in any manner detracting from its
intended purpose in contouring support for the contents being
displayed and in secure engagement of the article being displayed.
As can be seen from the drawings herein, the pre-form of the
invention has all of the advantages as the conventional pre-form
which is adapted to enclose the entire powder compact over the top
rather than through the compact itself.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIGS. 1 through 6, the assembled compact display unit
14 comprises panel 16, hang hole 18, face powder compact 20,
pre-formed blister 50 which passes through the compact between the
top 22 and bottom 24 over the face powder 38 which is contained in
the compact within the powder chamber 36.
The compact is of the conventional type, preferably made of plastic
material and is provided with mirror 34 in the top 22, mirror 34
being retained within the mirror well or chamber 32. The bottom of
the compact 24 is latched to the top by latch 26 and is opened from
the latch by the upward swinging movement of the top from hinge 44.
The compact is provided with the usual powder puff 42.
The details of the blister are best shown in FIGS. 7 and 8 but
these details can be more readily understood by reference to FIGS.
1 and 2 with respect to the compact, FIG. 1 showing the compact in
closed position and FIG. 2 the compact in opened position.
The pre-formed blister 50 which is generally ovoid in construction,
has a flange 60 which projects at the base, the width of the flange
being substantially uniform throughout except for the flat cuts at
the right and left sides as shown in FIG. 7, these being termed
flats to denote the straight edge adapting the heat seal to the
straight sides of the panel 16. At the very top and at the very
bottom of the blister 50 in the 12 o'clock position and in the 6
o'clock position there are provided the two critical cut-out
portions within the dome of the blister 52, the dome or top wall
being cut out along a straight line tangent to the chamber of the
powder, powder well 36 of the bottom of the compact. The two flange
portions at the base 62 which surround the lower portion of the
blister are designated as the terminators of the flange 60 at the
hinge end and these terminators are given reference numeral 62.
These terminators extend toward each other to be separated by a
distance just equal to the extent or width of the hinge 44. In the
particular preferred embodiment which is used commercially, this
width of the hinge is slightly smaller than the transverse
dimension of the slasp at the 6 o'clock position in FIGS. 1 and 2
and the blister portions for the clasp that correspond to the clasp
and latch elements 26, 28 and 30 are 66 and 68 in the blister
overlying the clasp.
In the embodiment of compact display unit 14 shown in FIGS. 1
through 6, the plate-like backing member to which the enclosing
blister 50 is attached by heat sealing is preferably formed of
cardboard which contains a sizing coating and constitutes panel 16.
The purpose of the sizing coating is to prevent the penetration of
printing ink. The display unit is printed and hung by the hang hole
18. High quality printing is not achieved unless the cardboard is
treated and this treatment is conventional.
The novel features of the generally oval shaped or ovoid pre-formed
blister consisting of a relatively heavy gauge and rigid synthetic
resin sheet material subjected to the pre-forming and cutting
process for manufacturing of the blister is shown in FIGS. 7 and 8.
The blister 50 which has been pre-formed and cut comprises a dome
or top 52, pre-formed and shaped side walls 54 and a flange 60.
The flange 60 is provided with diametrically opposed flat areas 70
which are aligned with the edges of the display card 16 during the
heat sealing procedure in order to center the compact 20 and
blister 50 thereon. Within the top or dome 52 there is an
indentation surrounding the entire dome constituting a depending
stiffening groove which fits into a recess just within the edge of
the bottom 24 of the compact 20. This depending stiffening groove
56 stiffens the dome or top wall 52 in much the same fashion as
corrugations stiffen a cardboard panel. A critical feature of the
special blister construction 50 of the present invention is the
triangular cut out portion 57 having a base 58 and sides 59 which
with relation to the sides 54 presents the appearance of a
triangular cut out section. The length of the straight line portion
of the base portion 58 is the length of an arc which lies parallel
to the hinge and is tangent to the edge of the powder chamber 36 of
the compact. Since the powder 38 which is held within the powder
chamber 36 has its own cover and since the dome portion or top of
the top wall 52 which extends rearwardly from the cut out 58 covers
the entire powder chamber 36 and its contents of powder 38, there
is no possibility for tampering with the package by the purchaser
to take place during which a cut can be made in the powder chamber
cover to thereby dissipate the contents. The flange 60 terminates
at a termination end 62 immediately behind the hinge. This permits
the flange termination sections to be heat sealed to the panel 16
or to alternate panels 76, 86 or 96 shown in FIGS. 9, 10 and 11,
respectively, to assure that the hinge is flanked on each side by
the termination 62 of the flange. In this manner a unique
characteristic of the mounting of the blister about the hinge is
provided based upon the termination portion 62 of each side of the
flange coming into registry at each side of the hinge 44 of the
compact 20.
In the formation of the blister 50 the side walls 54 at the
triangular cut-out 57 are turned inwardly to accommodate the hinge
44 to form the flange 64 as best seen in FIG. 6.
As shown in FIGS. 7 and 8, the opposite side of the cut-out
straight edge 58 and its cooperating terminating flange ends 62
provides a locking dome assembly comprising the intermediate
projection at the side wall 54 to which there has been applied
reference numeral 68. This intermediate projection lies
intermediate to projections 66, whose relationship to 68 is similar
to those of the terminating ends 62. By the term "similar" it is
intended to point out that the right side projection of the
termination 62 which terminates from the flange lies generally
opposite to element 66 which is the right side projection away from
the clasp cover. In similar fashion the left flange termination end
62 lies generally opposite the left side projection from the side
wall 54. In short, the flange termination portions 62 at the left
and right respectively extend to the edge of the straight line cut
58 at the top of the blister and the corner at the left of straight
edge 58 is in line with the left intermediate projection 66 while
the right corner 58 is in line with the right projection 66. In
effect, the two projections 66 left and right register the bottom
clasp of the compact at the latch 26 to permit the latching element
of the compact 28 to fit over the intermediate projection 68 with
the left and right projections 66 holding the compact 20 in fixed
position so that the latch and latching elements 26 and 28,
respectively, are located at the 6 o'clock position. With this
particular location it will be seen from FIG. 8 that the depending
stiffening groove 56 anchors the top wall 52 of the blister 50 in a
flat and smooth position between the hinge of the compact 44 and
the clasp. The purchaser simply opens the latching element 28 by
manipulating manually element 28 in the upward direction. The latch
releases from the keeper 30 which holds the compact to the bottom
and the cover constituting the top 22 of the compact swings open in
the view shown in FIG. 2. A large mirror 34 extending substantially
the entire inner dimensions of the cover comprising the top 22 is
mounted within the mirror chamber 32. The purchaser, with the
mirror open, can in one glance check the complexion in the image
seen in the mirror for its shade against the shade of the cosmetic
powder and determine at a glance whether the shade is a match for
that which the purchase is wearing or represents an improvement or
represents a shade which is not as suitable and therefore would be
discarded. Without disturbing the compact display combination, the
cover is closed by swinging the top 22 to the closed position shown
in FIG. 1.
In FIGS. 9, 10 and 11 there are shown panels to which the blister
is heat sealed in much the same fashion as the heat seal 72 is
accomplished with the pre-formed blister in FIGS. 1 through 6. In
FIG. 9 the panel is identified by reference numeral 16 and consists
of a relatively rigid cardboard or similar cellulosic stock
material which is coated with a coating adapted for printing,
coating 78. Printing on uncoated cardboard can be accomplished but
the distinctness of the indicia will not be as good as where a base
coat is applied to the cardboard. Coated cardboard uses
conventional synthetic resin coating material.
In the embodiment shown in FIG. 11, the panel 96 is provided with a
coating of metallic aluminum 100 which overlies a primary coating
of plastic 98. Aluminum coating which can be applied in a very thin
layer of the order of 1/10 of a mil permits the heat to be
dissipated very quickly during heat sealing and permits good
adhesion. In the embodiment of FIG. 10 the panel 86 is provided
with a plastic coating which has a very substantial heat
conductivity and is adapted to the heat seal. Such coatings are
well known in the art. An example of a good heat sealing coating is
made of plastic material to supply the desired properties of
plastic coating 88 in FIG. 10 is furnished by coating with
cellulose esters such as cellulose acetate and cellulose
propionate. A wide selection of operating temperatures may be made
by proper selection of the synthetic plastic material which is used
for the coating. Vinyl resins which are co-polymers of vinyl
chloride and vinyl acetate may be used to coat the panel 86 in
providing plastic coating 88 in FIG. 10.
An important advantage of the special blister pack assembly in the
present novel display panel unit 14 which is shown in FIGS. 1 and 2
lies in the fact that the powder puff 42 can not be easily removed
from the package without destroying the blister. Destruction of the
blister 50, since it is formed of a rigid heavy gauge plastic
material, requires very great effort and would be readily
noticeable. Accordingly, a comparison with shrink pack panel
display units which have been described herein for the prior art
compact, the present blister pack construction is more resistant to
tampering and pilferage, more economical to construct, and sturdier
in its appearance and in its display function. The powder puff can
easily be retrieved from the prior art shrink pack but cannot be
retrieved from the special package display unit of the present
invention.
Although the above description has been set forth with relation to
a round compact 20 having curved sides, where a top and bottom are
hinged and are closed, it is within the scope of the invention to
utilize the oval shaped blister for a generally rectangular compact
having its hinge opposite its clasp with the same curved
relationship at the sides so that the top and bottom taper to a
fine edge in much the same manner as a watch tapers at the
edge.
