Abstract
ABSTRACT
The invention provides a package having a transparent blister defining a main cavity and a peripheral flange lying in a plane about the cavity. A substrate is attached to the blister so as to close the cavity with the product lying between the blister and the substrate. The cavity is divided by at least one fold in the blister into a primary pocket containing the product and at least one secondary pocket which is empty to form a shock absorbing structure. Damage to the blister in the area where the product rests against the blister caused by impacts of the product on the blister walls are minimized by the resilience of the shock-absorbing structure which effectively provides a minimum of three layers of blister material to be penetrated before the product can protrude from the package.

REINFORCED BLISTER PACKAGE
This invention relates to packaging for displaying products in retail stores and more particularly to blister packages containing a transparent blister attached to a substrate and defining a cavity containing a product.
It has become common to package products for sale at the retail level ~etween a transparent blister and a substrate attached to the blister and capable of receiving printed graphics. The substrate also combines with the blister to define an opening for suspending the package from a wall hanger so that the packages are available for visual inspection by potential purchasers.
The blister is vacuum formed from a transparent plastic sheet and then the product is laid in a cavity formed in the blister before the substrate is added to seal the blister and retain the product in the package. There is commonly no means provided for inspecting the actual product other than by a visual inspection through the blister. The user purchases the product in the package and then separates the pro~duct from the package after purchase. This separation is made possible by providing a laminated substrate which can be destroyed to provide access to the product.
The material of the blister must be kept to a minimum to reduce costs and it is therefore essential to design the blister in such a way that it will retain its shape and provide an attractive appearance yet use a minimum of material. The walls consequently have to be designed in such a way that -~$
- ~L2~36~:6~
although thin, they withstand deformation from minor impacts and do not collapse or, if deflected, rebound to their original shape.
Another consideration is that the overall package must retain a desirable appearance for its shelf life. This appearance can be affected by such things as rupture and puncture of the package caused by impact of the product on the blister walls. Such impacts are particularly damaging where the portion of the product which rests against the blister has sharp edges. Characteristically, such damaging impacts occur when a product on dis lay is accidentally dropped by a consumer or falls from the display wall. Also similar damage can result from careless handling of the cartons transporting the packaged products prior to delivery.
Such damaging deformation sullies the overall appearance of the package which then looks like an old product that has been on the shelf for a long time. A consequence of this is often that the product is left on the shelf because the purchaser prefers to select other products in undamaged packages. The retailer is then left with a product which has to be sold at a discount.
The object of this invention is to provide a blister package which is less prone to the damage caused by impacts of the aforementioned type so as to maximize the appearance of the displayed package.
Accordingly, in one of its aspects, the invention provides a blister package for displaying a product. The package has a transparent blister defining a cavity and a 6Z6~
substrate attached to the blister so as to close the cavity with the product lying between the blister and the substrate. The blister includes a shock absorbing structure having at least one fold in a portion of the blister so as to divide the cavity into a primary pocket containing the product and at least one secondary pocket which is empty.
An exemplary package incorporating a preferred embodiment of the invention will be described in detail with reference to the drawings, in which:
Fig. 1 is a perspective view of a plurality of blister packages made according to the invention and suspended from a conventional wall rack to display the packages;
Fig. 2 is an exploded perspective view of one of the packages drawn to a larger scale and showing an exemplary product to be contained in a blister forming part of the package;
Fig. 3 (drawn adjacent Fig. 1) is a view looking at the blister side of the package, this view being to a larger scale than that used in Fig. 2 and showing the bottom end of the package; and Fig. 4 (also drawn adjacent Fig. 1) is a sectional view on line 4-4 of Fig. 3.
Reference is made firstly to Fig. 1 which illustrates generally the conventional use of the exemplary blister package. As seen in Fig. 1, a plurality of blister packages 20 are suspended from a hanger 22 supported from pegboard 24 of a display wall 26. Different packages 28, also made according to the invention, are suspended from a second hanger 30 attached to the pegboard 24. In the example shown, the packages 20 contain -~` 1286~
a first size of wiper blade and the packages 28 a longer wiper blade. These exemplary packages are of course examples of packages which can be of a great variety of shapes and size depending upon the product to be contained. Also, it is preferred in marketing wiper blades to arrange the packaging so that the transparent blister faces the wall 24 and the flat side formed by the substrate is printed and facing potential purchasers. Anyone interested in ]purchasing the product can lift the package off the hanger and inspect the product visually through the bliste~ This arrangement is considered to provide enhanced point-of-sale appearance and, although not essential, it is preferred in this example.
Reference is next made to Fig. 2 which illustrates one of the packages 20 before assembly to contain an exemplary wiper blade 31. The package consists essentially of a blister designated generally by the numeral 32 and substrate 34. The blister has a cavity 36 including a stepped side wall 38 which follows generally the contour of the wiper blade. The wall is interrupted by a flat portion 40 which, because it meets the step portion of the side wall 38, defines a rigid structure to strengthen the wall. Similarly, a pair of buttresses 42 are provided on the opposite side of the cavity 36 to strengthen the wall in this portion, and a further pair of buttresses 46, 48 are provided to reinforce the upper extremity of the cavity 36 and to strengthen the finished package in the portion used to suspend the package on the hanger 22 (Fig.l).
A peripheral flange 52 extends in a common plane about the cavity 36 and terminates at the top end of the blister 32 in ~2~2~
a header generally indicated by numeral 58. A cut-out 50 is formed in the flange 52 in the area of the header 58 and, in use, receives the hanger 22 (Fig. 2) for suspending the package 20.
At the bottom end of the blister 32, the flange 52 is interrupted to define a secondary ravity 54 used for parts which are supplied with the wiper blade 31 and which, for simplicity, are not shown in the drawings. The bottom end of the blister 32 has a shock-absorbing structure 69 including a fold 70 which 10 divides the cavity 36 into a primary pocket 71 (Fig.4) containing the wiper and a small empty secondary pocket 72.
This part of the blister 32 will be described more fully with reference to Figs. 3 and 4 where it is drawn to a larger scale.
The substrate 34 is made up of at least two layers which are readily delaminated. A first layer 59 forms an inner surface and the outer surface is formed by a second layer 60.
The substrate 34 is shaped to be essentially coextensive with the blister 32 but in fact deviates in some places to prevent premature delamination of the substrate. The surface of the first layer 59 is interrupted by a score line 62 about an area 63. The score line 62 follows generally the contour of the main cavity 36 and penetrates the first layer 59 of the substrate so as to preserve the integrity of the area 63 and any instructions printed on the substrate in this area. This first layer 59 is preferably heat sensitive so that it can be heat sealed to the blister 32 to contain the wiper blade 31. The substrate 34 also defines a cut-out 64 for registration generally with the cut-out 50 of the blister 32.
iL2l~36~
Further detail of the bottom end of the blister 32 will now be described with reference to Figs. 3 and 4. The fold 70 comprises a curved connecting portion 74 located between the primary pocket 71 of cavity 36 and the secondary pocket 72. The portion 74 connects an inclined end wall 76 of the primary pocket to a shorter first wall 78 of the secondary pocket 72 and lies adjacent to the substrate 34.
In this way, the aforementioned walls 76 and 78 diverge away from the substrate and are resiliently movable between a relatively unstable first position in which they are compressed towards each other and a relatively stable second position (as drawn) in which they are spaced from each other. Because of this resiliency, the fold 70 behaves like a shock absorber and cushions any impacts from the wiper 31.
Moreover, it will be appreciated that three layers of the material composing the blister 32 must be penetrated by the wiper 31 before rupture of the package 20 will result in the wiper protruding beyond the extremity of the substrate.
To further improve the strength and resilience of the bottom end of the blister 32, the wall 76 of the primary pocket 71 and a second wall 80 opposite to the first wall 78 of the secondary pocket 72 are each provided with a set of parallel, ribs 82 and 84 respectively which extend away from the substrate. The ribs 82, 84 also minimize the risk of the walls being deflected inwardly and the strength of the walls 76, 80 is such that they will tend to rebound back to their original shape.
In use the walls 76, 78 will be in the positions shown in the Figs, and particularly Fig. 4. Should the package be 9 2~6~6~
dropped on the bottom end (as drawn in Fig.l) the product will create an impact loading initially on the inside of wall 76.
Some resilient deformation will take place as the r~ibs 84 deform and further energy will be absorbed by this wall being pushed towards the end of the package. As this happens, the connecting portion 74 and wall 78 will be deformed and there will also be a tendency for the substrate to be pushed out of its planar shape. All of these movements absorb impact energy. If more energy is stored, the wall 76 may be broken and in very extreme conditions the wall 78 may also be broken. However, under normal conditions, no further breakage will occur resulting in the package remaining in acceptable condition for display.
It will be appreciated that the package can be modified in many ways within the principles described with reference to the example given. In particular the relative depths of the primary and secondary pockets can be changed as desired. In general, the more material used for form the walls 76, 78, the greater will be the shock-absorbing characteristics. Further, the blister can be shaped to take a variety of products and the fold arranged to divide the cavity into a number of auxiliary pockets of varying size.
The preferred material for the blister is 10 mil polyvinylchloride and the substrate is preferably bleached sulphite board (20 point) coated on the outer surface with a high heat seal varnish and on the inner surface with polyvinylchloride. The substrate is scored lightly to penetrate the polyvinylchloride coating without showing through on the other side of the substrate. Different materials could be used consistent with being able to attach one to the other either by heat sealing or adhesive.
