Description
This invention relates to a carded package and particularly to a
novel and highly versatile type of package.
There are, in general, three basic types of packages. The first
type of package involves a thermo-formed plastic cup which is
either heat sealed onto a card or held between layers of a
multi-layer card, usually in an opening. This is commonly referred
to as a blister pack.
The second type is called "Skin Pack." In this method the product
is used as a mold or die. The extruded thermoplastic shrink film is
flowed on the card in a vacuum and immobilizes the product.
A third type is called "Stretch Pack" and uses a die-cut card with
a plastic window. The card is put over an open mold and a vacuum
applied, whereupon the film takes the contour of the mold. The card
is then folded over the product which is encased between two layers
of film. Hot air then shrinks the film around the product to hold
it tightly.
The present invention offers the following advantages over these
above methods:
1. Due to use of a smaller board, it requires less shelf space.
2. The product can often be either spindled or self-standing.
3. A tear tab with perforations can be readily added to facilitate
removal of the product from the card which is often difficult with
the other methods.
4. It is useful for large containers which are often difficult to
package with other methods.
Accordingly, it is an object of the present invention to provide a
carded package which can be produced at high speed and low cost
since less card material can be used.
Yet another object of the present invention is to provide a carded
package which is extremely attractive.
Still another object of the present invention is to provide a
carded package which will readily accept printing or descriptive
matter on the film material and/or the card.
Still another object of the present invention is to provide a
carded package which is highly versatile and which minimizes the
need of special components for each package.
Still another object of the present invention is to provide a
package which can be suspended from a hook or spindle.
The foregoing as well as other objects of the invention are
achieved by providing an improved package that comprises a
container, a band of thermoplastic heat shrinkable tubing in
contact with one or both of the container and card in order to make
a package. The card may specifically engage the container cap or
the container may be simply physically held to the card by the heat
shrinkable band. The card may essentially embrace the container or
the heat shrinkable band can hold more than one container to the
card. Tabs may extend from the card in order to hold the container
or, alternatively, to hold the heat shrinkable tubing. The card may
be formed with slots or notches in order to hold the heat
shrinkable tubing or the heat shrinkable tubing can be adhesively
adhered to the card by either a line of adhesive or a spot of
adhesive.
In all cases, the package is completed by elevating the temperature
such that the heat shrinkable band will shrink so that the
container, card and band will be brought together to produce a
stable package.
The card may be ornamented or may carry printed matter, such that
the card can function as a label. The tubing can be either seamless
or made from film with a seam and is readily available on the
market. The tubing may be plain or it may be attractively
colored.
In certain instances, the interior surface of the tubing may be
provided with a heat reactive coating in order to enhance the bond
between the tubing and the container or bottle.
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 detailed description when

Referring now to the various figures of the drawings wherein like
reference characters refer to like parts, there is shown in FIGS. 1
to 13 various embodiments of the present invention. There are three
elements in each embodiment. First, there is the merchandise, such
as a bottle, box, tube, vial, can or other container. Second, there
is a card having a particular configuration or slot. Third, there
is a heat shrinkable tube in the form of a seamless or seamed band
cut to size.
The heat shrinkable tube may be transparent to permit visibility of
the carded merchandise, but may also be translucent or opaque and
of varying colors. Also, the heat shrinkable tube may contain
printing.
It will be seen that in the first seven embodiments of the
invention, the merchandise is initially placed in contact with or
adjacent to the card and then the heat shrinkable tube is applied.
In the latter embodiments of the invention, the heat shrinkable
tube is initially placed in contact with the card, and then the
merchandise is inserted.
The final step in all cases is to shrink the tube in place. The
heat shrinking step can be carried out in various ways known to the
art including the use of a heat gun or a conventional heat
tunnel.
Where the term "card" is used, it is intended that such a term may
be broadly construed to include not only conventional cardboard,
but also plastics, metal and other materials used singly or in
combination, well known to those skilled in the art.
Reference is now made to FIG. 1 which shows a card secured to a cap
and resting upon the neck of a bottle.
It will be seen from FIG. 1 that the package 10 includes bottle 12
having upper portion 14 that terminates in a neck that receives a
cap 16. Cap 16 includes lips 17 and 19. The card 18 includes a cut
away portion in which cap 16 is positioned, and the cut away
portion includes ridges and valleys corresponding to the contours
of the cap 16. The card 18 also includes side portions 20 that slip
about the cap 16, with the lower edges 22 of the side portions 20
resting upon the upper portion of the bottle 12. The heat
shrinkable tubing is simply slipped about the portion of the card
18 and cap 16 and then shrunk in place. Where desired, a series of
perforations 24 may be formed in the card 18 in order to enhance
the adhesion of the heat shrinkable tubing to the card 18.
As further shown in FIG. 1, the card 18 also includes an upper
extension 22 which may be removed by severance along line 28. The
upper portion 26 is optional for the purpose of receiving printed
information, and can include a hole for hanging on a hook or
spindle.
In some instances, the side extensions 22 of the card 18 may be
extended completely or partially down the sides of the bottle
12.
Reference is now made to package 30 of FIG. 2-B wherein the bottle
or the cap has a pronounced lip.
The card 32 is shown in FIG. 2-A as possessing a head portion 34,
from which extends the cap engaging portion 36 having slots 38 and
40 to receive the lips of the container or cap. Clearly, where the
cap or container has only one lip, then only one of the slots 38
and 40 need be supplied.
In use, the card 32 is brought in contact with container 42 so that
the lips 44 and 46 are received respectively in slots 38 and 40. As
shown in FIG. 2-B, the card may be curved as allowed by the contour
of the upper portion of the bottle. A heat shrink band 48 is then
simply applied in the same manner as heat shrink band 23 of FIG. 1.
It is to be noted that the lower edge 50 of the card 32 rests on
the shoulder 52 of the bottle 42. Also, the card may be preformed
to be a three dimensional curve or straight sided figure. The card
may also contain a hole in the upper portion suitable for
suspending the package from a hook or spindle.
FIG. 3-A and FIG. 3-B shows a package that is created where the
bottle or cap do not have a pronounced lip. Here, the package 60
includes a card 62 having two cut away areas 64 that define a
tongue 66 in which is formed a hole 68. The tongue may optionally
include flap 70. The cap 72 of bottle 74 is seated in the hole 68,
with the tongue 66 being wrapped about the cap 72 as shown in FIG.
3-B. The card may also contain a hole suitable for suspending the
package from a hook or spindle.
Reference is now made to FIGS. 4-A, 4-B and 4-C which show another
embodiment 100 of the invention to create a package where there is
inadequate lip area to hold a bottle to the card. In this
embodiment of the invention, the card 102 includes a narrow
depending tongue 104 that in some cases will have fluted sides 106
and/or openings 108 to enhance the securement of the card 102 to
the bottle 110 having cap 112.
After the bottle 110 and the card 102 are brought together, the
heat shrink band 114 is positioned about the bottle 110 and the
tongue 104 and heat is applied in the normal way. In some cases,
the fluted sides 106 may be dispensed with and replaced by straight
edges.
In other cases, the card 102 may include a depending section 116
having straight edges which terminate in a somewhat wider bottom
portion 118. The heat shrink band 120 is placed about only
essentially the middle portion of the package, with the wider
portion 118 preventing the heat shrink band 120 from working its
way off the package. In FIGS. 4-A, 4-B and 4-C, the upper portion
of the card 102 may receive printing.
Where the bottle has a lip, a suitable slot may be provided in the
card 102, and also the wider bottom section 118 may, in some cases,
be bent under the bottle.
Another embodiment of the invention is shown at 130 in FIG. 5-A
wherein two containers are secured together and to a card. In the
embodiment of FIG. 5-A, a can 132 and a bottle 134 are each held
against the card 136, and then a heat shrink band 139 having a
width essentially the same as the height of the bottle 134 is
slipped in place about the card 136. Heat is then applied in the
usual manner.
It will be seen that the card 136 may include a wider bottom and/or
top section 138 that essentially forms a notch to facilitate
securement of the card to the container.
It should also be noted that the devices of FIG. 5-B may also
include a card that can be bent to the contour of the bottle or
container. To that end, the card 136 may be bent along its
longitudinal edges (which are parallel to can 132) as shown in FIG.
5. In some cases, it may be desired to prebend the card into a
three dimensional form, depending upon assembly techniques that are
available. In other cases, the shrink energy of the band is
sufficient to bend the card to fit the contour of the container
without prebending or forming.
Reference is now made to FIGS. 6-A and 6-B which show embodiment
160 that is comprised of two or more panels or, in the case of FIG.
6-A, three panels. It will be seen that the card 162 includes three
panels 164, 166 and 168 that are defined by fold lines 170. Each
panel includes a large cut away section 172 and depending flaps 174
that can be folded under along lines 176.
As shown in FIG. 6-B, the card 162 is folded so that it embraces
the bottle 178 which has cap 180. The flaps 174 are folded
underneath the bottle and act as a retainer. A heat shrinkable band
is simply telescoped about at least the middle portion of the
panels 164, 166 and 168, and then heat is applied in order to make
a compact package wherein the bottle 178 can be seen through the
cut away areas 172. This construction eliminates the need for
gluing the sides together and the shrink band can cover the top
and/or bottom of the package.
Another embodiment wherein the container and the card are first
assembled is shown in FIGS. 7-A and 7-B as embodiment 200 wherein
card 202 has cut away ears 204 and 206. The upper ear 204 has an
opening 208 which receives the neck portion of bottle 210 having
cap 212.
The lower ear 206 serves to support the bottle 210. A heat
shrinkable band 214 is simply applied about the card 202 and the
bottle 210 in order to produce an economical package when heat is
applied. A variation of this is illustrated also in FIG. 7-A where
the lower ear is eliminated and the lower portion of the card cut
off as illustrated, for example, by the line A-A. This makes the
package capable of standing by itself and not needing a spindle or
hook for display.
Reference is now made to FIGS. 8-A, 8-B and 8-C wherein card 232
has at least one and preferably two cut out flaps 234 that serve to
hold heat shrinkable tubing 236 in a manner as best seen in FIG.
8-B. It will be seen that the heat shrinkable tube 236 is slipped
between one or both of the flaps 234 and the card 232.
Once the heat shrinkable tubing 236 is in place, a bottle 238 is
slipped into the heat shrinkable tube 236 and then heat applied in
order to shrink the tubing 236 and complete the package. It will be
seen from FIG. 8-A that a series of indentations assist in breaking
the card 232 away and separating it from the heat shrinkable tubing
236 and the bottle 238. A variation of this is illustrated in FIG.
8-A where the lower ear is eliminated and the lower portion of the
card cut off as illustrated, for example, by the line A-A. This
makes the package capable of standing by itself and not needing a
spindle or hook for display.
Another embodiment 250 of the invention is shown in FIG. 9-A and
FIG. 9-B wherein the card 252 has cut lines 254 adjacent to the
bottom 255. The cut lines 254 connect with open areas 256 that
communicate with elongated slots 258. The heat shrinkable tubing
260 is seated in the slots 258 by virtue of the access allowed by
cut lines 254 so that the heat shrinkable tubing can be threaded
through the cut lines 254, into openings 256 and then led into the
slots 258. As in FIG. 8-C, the bottle is then slipped into the heat
shrinkable tubing and heat applied to complete the package.
Reference is now made to FIG. 10-A which shows yet another
embodiment 280 of the invention wherein the card 282 has applied to
one face a thin line 284 of adhesive. The heat shrinkable tubing
286 is simply adhered to the card 282 along the adhesive line 284.
As shown in FIG. 10-B, a bottle 288 is then inserted within the
heat shrinkable tubing 286 and heat is applied to complete the
package.
In embodiment 300 of FIG. 11, the card 302 has an area of adhesive
304 located within the confines of a perforated area on the tubing,
by which heat shrinkable tubing 306 is attached to the card 302.
This embodiment has the advantage of easier removal of the card
from the heat shrinkable tubing 306 and its container product
allowing the printed tubing to remain on the container to serve as
the permanent label of the container as it would be used normally.
Therefore:
a. one card serves as a label and means for mechanically holding
the tube to the card.
b. after removal from card, the tube serves as the standard label
of the container.
Reference is now made to FIGS. 12-A and 12-B which show embodiment
320 that includes a one or two-ply card 322 having a cut away
tongue 324 adjacent the lower portion thereof. A heat shrinkable
band 326 is slipped between the tongue 324 and the card 322, and
then the container or product is placed in the heat shrinkable
band, followed by the application of heat.
As shown in FIG. 12-B, the card 322 is preferably of two plies 328
and 330 so that the heat shrinkable band 326 will be held between
the plies 328 and 330. The upper portion of the card 322 is
reserved for printing. The card may be of a single ply rather than
two ply.
In another embodiment of the invention as shown in FIGS. 13A, 13B
and 13C, the adhesive is coated on one or both sides of the heat
shrinkable film and dried before the film 408 is seamed into a
tube. The two ends 404 of the film are then taken and bent around
the card 402 (FIG. 13B) and adhered or heat sealed to the back side
of the card forming a loop as illustrated in FIG. 13B to hold
bottle 406 against card 402.
As will be evident to those skilled in the art, the foregoing
examples illustrate some of the various ways, within the scope of
the invention, wherein heat shrinkable tubing may be utilized to
combine a card and a container.
The heat shrinkable band, in many cases, is easily removed from the
card without disturbing the contents. For instance, see the
embodiment of FIGS. 12-A and 12-B which also constitute a package
having a lower unit cost and wherein the film acts as a label or an
advertisement.
It has been found that the heat shrinkable tube avoids the handling
problems of the more familiar film. Furthermore, with heat
shrinkable tubing, there is no necessity to maintain an inventory
of premolded parts.
In many cases, a narrow heat shrinkable band can be used to secure
the card to the container either in the cap area of around the body
of the container. This will greatly reduce the amount of tubing
needed compared to other methods. This is particularly applicable
when the adhesive coated tube is used.
The heat shrinkable band may be furnished with a tear strip for
ease of opening as contrasted with other packages of the prior art
which require the use of a sharp instrument for opening.
Prior to use, the heat shrinkable tubing can be stored flat in the
collapsed condition in rolls and cut to size as needed, thereby
saving space and reducing inventory. This is also true of the
carded band. Furthermore, the card does not necessarily have to be
larger than the container as was the case with previous
packages.
The heat shrinkable tubing is preferably polyvinyl chloride and can
be either seamed or seamless of any desired thickness. It is
desirable, but not required, for the tubing to have a high degree
of shrinkage in the radial direction and a low shrinkage in the
longitudinal direction. An essentially monoaxially oriented film
seamed into a tube makes a highly desirable band material. Such a
material will make an attractive package after shrinking into place
particularly in the case where the band contains a printed message.
However, it should be understood that other materials, such as
polyethylene or a polyfluoride or Saran may be employed, and still
other materials will occur to those skilled in the art, the only
requisite being that the band or tubing will undergo adequate
shrinking either through the application of heat or other special
physical environment.
In some cases, it may be desirable to apply a heat reactive coating
to the interior surface of the tubing, for instance, in the
packages of FIGS. 13A, 13B and 13C. An example of such a heat
reactive coating is one that includes, as the active ingredient,
ethylene vinyl acetate. This coating becomes active under the
application of heat to create a good cohesive bond with a bottle or
other container that will be held by the heat shrinkable tubing or
band. In some cases, the entire interior surface will be coated and
in other cases, the coating will just be applied in a pattern or
series of bands. While the bottle or other container will be
tightly held, nevertheless, the band can still be easily zipped
away in a tearing action.
The band can be made from rolls of film, by machinery which will
cut an unseamed strip of film automatically and apply the same onto
the card and the container, then sealing the film into a band. The
term "band" or "tubing" as used herein also contemplates this form
of the invention.
In all cases, the package, whether held in a jig or fixture, or
simply assembled, is then subjected to an elevated temperature of
approximately 300.degree. F., but, of course, this temperature will
vary in accordance with the specific nature of the heat shrink band
or tubing as well as in view of the desired elapsed time of heat
application. The heating step may take place in a heat tunnel or
the heat may be applied in a jet or by way of a heat gun.
While the band or tubing has been shown and described as having a
circular form, in some cases the band or tubing may take on or be
given other forms, such as a square or rectangular
configuration.
Without further elaboration, the foregoing will so fully illustrate
our invention that others may, by applying current or future
knowledge, readily adapt the same for use under various conditions
of service.
