Description
WO 99/35039 PCT/US98/23919 OVERWRAP TRAYPACK 5 Background of the Invention 1. Field of the Invention 10 This invention relates to overwraps which are utilized to surround and hold a plurality of packages for shipment and also, if desired, for retail display while minimizing the amount of waste packaging material. 15 2. Description of Related Art For many years efforts have been ongoing to optimize wrapping and display materials for packages, such as small boxes, cassettes, etc., which are grouped together 20 for shipping and display but intended to be sold separately through retail outlets. The efforts have been focused on both the shipping aspect, where durability and strength are important, and the display aspect, where visibility and stability are important. The common resulting situation is that separate materials are often used for wrapping the items during shipping and for displaying the items at a retail level. For example, a plastic 25 film overwrap may be utilized to wrap the items during shipping and then removed in favor of a separate cardboard or other hard display tray which is used to display the items. The result of this common situation is that an excessive amount of material is utilized and retailers who do not wish to use the provided display are faced with the necessity of disposal of the bulky display tray, as well as the overwrap material, without receiving any 30 benefit from the tray. Not only is this an inconvenience for the retailer and a waste of material, but it also raises environmental concerns; as the world's landfills are becoming WO 99/35039 PCT/US98/23919 ever more full the public is becoming ever more conscious of attempting to reduce waste materials. Generally, existing package overwraps are not sufficient, by themselves, 5 for use in retail product displays. Among the problems with the use of overwraps for display are that once overwraps are opened they do not provide the support, stability and/or visibility required for display purposes. Further, one of the most common methods of overwrapping, heat-shrinking, does not address the shipping/display issue. For example, U.S. Patent No. 5,048,687, issued to Suzuki et al. discloses a unit 10 containing a number of packages wherein the packages are wrapped in a tubular outer wrap. The outer wrap consists of a flexible plastic film having top and bottom portions which are heat-shrinkable such that the inner packages are tightly bound together when the film is heat shrunk. Likewise, U.S. Patent No. 5,097,955, issued to Kluter et al. and U.S. Patent No. 5,067,612, issued to Tsuchiya et al. both also disclose units wherein the 15 packages are ultimately bound together via shrink wrapping. The shrink wrapping process of these references produces a tight, strong package for shipping, however the shrink wrap material is not capable of being utilized for display purposes and consequently a separate display must be provided. 20 It would be advantageous to provide a combination display tray and overwrap which would provide the properties sufficient to allow shipping of the package as well as proper retail display. It would be further advantageous if the overwrap and tray reduced or eliminated the need to discard bulky unwanted or depleted trays. 2 WO 99/35039 PCT/US98/23919 Summary of the Invention The present invention is directed to a combination overwrap and display tray for holding a plurality of packages for shipping and display. The present invention employs a polypropylene overwrap having a tear off means which encircles the overwrap. The 5 overwrap is utilized to group the plurality of packages during shipping and for display purposes and the tear off means is used to remove a designated portion of the overwrap, thus exposing the individual packages at the retail location. The remaining portion of the overwrap may be utilized as a tray for retail sale and no separate tray is required. 10 Brief Description of the Drawings Figure 1 is a perspective view of a plurality of packages entirely enclosed by the overwrap of the present invention. 15 Figure 2 is a perspective view of a plurality of packages entirely enclosed by the overwrap of the present invention with the tear strip removed. Figure 3 is a perspective view of a plurality of packages partially enclosed by the overwrap of the present invention. 20 Figure 4 is a perspective view of a plurality of packages with the top portion of the overwrap being removed. 3 WO 99/35039 PCT/US98/23919 Figure 5 is a perspective view of the present invention as on retail display with two of the plurality of packages removed. Detailed Description of the Present Invention 5 Reference will now be made to the presently preferred embodiments of the present invention. As illustrated in Figures 1 and 2, the present invention discloses a plurality of inner packages 11 which are held together via an outer overwrap 10. The overwrap completely encloses the plurality of packages and holds them all tightly together such that 10 the packages may be shipped or otherwise handled as a single unit. Preferred materials for theoverwrap are non-heat shrinkable materials including polypropylene, oriented polypropylene and foamed polypropylene. These materials are preferred due to their inherent stiffness and propensity to tear as desired. A means for separating one or more portions of the overwrap, and preferably the top portion of the overwrap from the bottom 15 portion of the overwrap, is also provided. Preferably the means is in the form of tear strip 15 which encircles the wrapper and is heat-bonded to the wrapper, however the polypropylene is preferably also be scored, perforated or otherwise adapted to facilitate straight, clean tearing. Most preferably, the tear strip is placed over perforations 16 in the overwrap. Any desired number of tear strips may be employed. The tear strip is 20 preferably located in a position such that when it is removed it pulls and removes the top portion of the overwrap, thus exposing the tops of the individual packages. At the same time, the bottom portion of the overwrap remains in place and holds the plurality of inner packages in place. The most preferable location for the tear strip is approximately at the midpoint of the sides of the packages. The width of the tear strip may be variable and, in 4 WO 99/35039 PCT/US98/23919 addition, pre-printed opening instructions, such as "pull up and around to open" may be printed on the strip. As shown in Figures 3 and 4, the removal of the tear strip will result in the removal 5 of the top portion 10 OC of the overwrap resulting in open area 10 OA which exposes the tops of the individual packages. The bottom portion of the overwrap remains in place over the bottom portions of the plurality of packages and acts as a tray 10OB for holding the packages in place. In this position, the packages may be neatly and securely displayed in a manner such that the retail customer may easily remove one or more of the packages for purchase. 10 The consistency of tray 10 OB is such that one or more packages may be easily removed from the tray. As illustrated in Figure 5, opening 11 A created by the removal of one or more packages does not damage the integrity of tray 10B. The tray portion 10B of the overwrap retains sufficient strength to hold any number of remaining packages in place upon the removal of one or more packages. In the event that the retailer does not desire to 15 utilize the bottom portion of the overwrap as a tray, then only the small amount of polypropylene material which constitutes the bottom of the overwrap must be discarded. In any event, following the depletion of the packages only a small amount of waste material must be discarded. This is in stark contrast to currently available overwrap systems which require a separate, bulky tray portion which creates a large amount of waste 20 when discarded. The overwrap itself comprises a six-sided wrap such that all six sides of the plurality of packages are covered. The wrapping is formed around the plurality of inner packages and then sealed on both its top and the bottom ends so that the sealing portion 5 WO 99/35039 PCT/US98/23919 does not interfere with the tear off strip or strips. The wrapping process may take place on virtually any standard wrapping machine. Preferably, the wrapping is done with the grain of the polypropylene, i.e., the grain is in the same direction as the tear strip, in order to enhance the tearing of the wrapping. Following the wrapping process, the 5 polypropylene is heat sealed to itself on both the top and bottom of the package to produce a tightly wrapped package. The wrapping is not amenable to or subjected to a heat-shrinking step. In a preferred embodiment, the wrapping contains pre-printed graphics, most preferably on the bottom portion of the overwrap, in the form of instructions which instruct the shelf stocker to remove the top portion of the overwrap 10 and to leave the bottom portion of the overwrap on the packages for use as a tray. The final step is the addition of a tear-off strip and preferably perforations or other means to allow the top portion of the package to be neatly separated from the bottom portion. The tear-off strip may be heat sealed or otherwise affixed to the package. 15 While there have been described what are presently believed to be the preferred embodiments of the present invention, those skilled in the art will realize that various changes and modifications may be made to the invention without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within the scope of the invention. 6
