INDICIA FOR CONTAINERS

Abstract: A container (10) having an outer removable overlying label (32) which covers an underlying permanently affixed label (34). The outer label (32) is at least partially translucent, or preferably transparent. Use of a removable outer label (32) permits the consumer to remove some or all of the verbiage which is important for the label, but which need not be present on the container (10) in use in the consumer's home. In an alternative embodiment, the outer label (32) is removably affixed to a wall of the container (10).

Description: INDICIA FOR CONTAINERS The present invention relates to containers having an outer removable overlying label which covers an underlying permanently affixed label. More particularly, the present invention relates to containers wherein the outer label is at least partially translucent, or preferably transparent. In the intensely competitive markets for consumer goods, manufacturers attempt to capture the long term attention of consumers with their improved products. However, initially the consumer' s attention must be attracted through advertising and/or product labelling. Often there is a need to communicate to the consumer several messages concerning the product. Therefore, the labels can become somewhat "busy." A goal which is sometimes in conflict with the need to impart extensive information through labelling is to provide the consumer with an attractive product, particularly an attractive container for use in the home. Much effort has been expended in recent years in designing containers having a pleasing appearance. However, labels brimming with verbiage can diminish the favorable aesthetic effect of the container . It is known to permanently adhere one ply to another. One of the plies may be a label. This is generally done for protection purposes. It is also known to adhere removably an opaque pressure sensitive label to a bottom ply. This has been done primarily to permit the consumer to remove the top label as a coupon, thereby leaving the bottom label intact. A product sold under the name "Herbal Essence" by Clairol in a 24 oz. container used a two-ply structure wherein both plies were clear, but wherein the plies were adhered using a varnish. It has now been discovered that the conflict between providing informative label graphics, and providing the consumer with an attractive container for use in the home, may be resolved by the use of a container having a removable label, preferably one which is at least partially transparent. Much or all of the indicia for attracting the attention of the consumer to the product can be displayed on the label, which may be removed after purchase. Underneath the label may be either a container wall or a second ply having label information, an attractive design, or nothing. In a particularly preferred feature of the invention, the underlying container wall or underlying second ply contains indicia, which may be seen through the first ply, thereby complementing the indicia on the top label. One and/or both plies may be made of polypropylene. Preferably the top label is adhered to the second ply or to the container wall with a reworkable pressure-sensitive adhesive such as an acrylic adhesive. In accordance with the invention, the top (or only) ply may be readily removed by the consumer with application of only modest force. The container of the invention may be used for various household products, including personal washing products such as liquid and semi-liquid washing products, soap bars and non-soap surfactant bars, laundry products such as detergents and fabric softeners and foods such as liquid and plastic margarines and other spreads. The container is preferably in the form of a thermoplastic bottle but may also be a carton or other container. For a more complete understanding of the above and other features and advantages of the invention, reference should be made to the detailed description of preferred embodiments and to the accompanying drawings. Fig. 1 is a front elevational view of a bottle according to the invention. Fig. 2 is a side elevational view of the bottle of Fig. 1. Fig. 3 is a top plan view of a label according to the invention. Fig. 4 is a cross section along the lines of 4-4 of Fig 3. Fig. 5 is a view similar to Fig. 4 but showing an alternate embodiment . Figure 1 shows a bottle 10 which includes a base 12, front wall 14, and a shoulder 18 leading to finish 20 having external threads 24 for mating with internal threads on a closure (not shown) . Bottle 10 further includes an opening 26 at its top for dispensing product and a labelling composite 30. Additional features may optionally be present such as a drainback fitment or a pumping mechanism. Figure 2 shows a side wall 16 of the bottle 10. Figure 4 shows that the labelling composite 30 includes two plies, a first or front ply 32 and second ply 34. Ply 32 is removably adhered to ply 34 by a reworkable pressure sensitive adhesive 36, which may be acrylic. It is especially preferred that a portion of at least the outer ply 32 is translucent, and more preferably transparent. It is, thus, desirable that at least a portion of underlying label 34 can be seen through upper label 32. For instance, in Fig. 3, it is possible to see the illustration 40 of a tree disposed on lower label 34 through transparent portions of upper label 32. This provides an interesting multi-dimensional effect for the consumer. Moreover, the consumer may remove the word-intensive upper label 32 easily by grasping label 32 at corner 42 and peeling it away from underlying ply 34. As a result, the container, which the consumer leaves in his or her bathroom, kitchen or other room, may include only a pleasant graphic design instead of the extensive verbiage which may be required on the outer label. Underlying ply 34 is preferably adhered to bottle wall 14 with a permanent acrylic adhesive. The following tables set forth the preferred and most preferred amounts of force needed to remove the removable and permanent labels using protocol PSTC 1 modified for 72 hour dwell time. Removable label adhered to: Most Preferred Preferred Stainless Steel: 19 oz/in avg. Range: 8-35 oz/in. Acrylic: 17 oz/in avg. Range: 8-35 oz/in. Glass: 15 oz/in avg. Range: 8-35 oz/in. Permanent label adhered to: Most Preferred Preferred Stainless Steel: 62 oz/in avg. Range: 50-75 oz/in. Acrylic: 74 oz/in avg. Range: 60-85 oz/in. Glass: 61 oz/in avg. Range: 50-75 oz/in. Polypropylene 46 oz/in avg. Range: 35-60 oz/in. In a preferred embodiment, the graphics on the front label and the graphics on the top label and on the underlying label complement each other. For instance, graphics on the upper label may form one part of the scene and graphics on the lower label may form a second part of the scene. However removal of the upper label will still leave the lower label with sufficient graphics to contribute to the attractive appearance of the container. While it is desirable that upper ply 32 is at least partially translucent, preferably transparent, it may also be desirable that underlying ply 34 be partially translucent or transparent to provide a desirable appearance for the container. As seen in Fig. 5, in accordance with an alternate embodiment of the invention, label structure 30' comprises label 32' removably adhered by acrylic adhesive 36' to bottle wall 34'. Bottle wall 34' may, for instance, have indicia for making the container more attractive or may lack any indicia whatsoever. In this embodiment it is preferred that label 32' is at least partially translucent, preferably transparent, although it may be opaque. Container 10 may be manufactured by any of the many well known manufacturing techniques including extrusion blow moulding, injection blow moulding and injection stretch blow moulding 1 or 2 stage. The container may be made from a number of materials, preferably thermoplastic materials such as polyethylene (HDPE, MDPE, LDPE, LLDPE) , polypropylene (PP, OPP) , polyvinyl chloride (PVC), polyethylene terephthalate (EPET, PETG, OPET) and polystyrene (PS, HIPS) . Other materials from which the plies may be made include polyethylene (HDPE, MDPE, LDPE, LLDPE), polypropylene (PP, OPP) , polyvinyl chloride (PVC) , polyethylene terephthalate (EPET, PETG, OPET) and polystyrene (PS, HIPS) . Other potentially suitable adhesive materials include acrylic based adhesives and rubber based adhesives. It should be understood, of course, that the specific forms of the invention herein illustrated and described are intended to be representative only as certain changes may be made therein without departing from the clear teachings of the disclosure. Accordingly, reference should be made to the appended claims in determining the full scope of the invention.
