The present invention is directed to a carton having a sensual feel. More particularly, the invention is directed to a carton in which at least part of the outer surface of the carton is covered with a coating that provides the covered portion with a sensual feel.
Cartons are widely used in various industries, including the consumer goods industry, for packaging various types of products. Cartons are used for primary packaging as well as secondary packaging (i.e. packaging which holds numerous packaged products are then bundled in secondary packaging for purposes of, for example, delivery or the selling of numerous packages together as one sale item). Such cartons are normally made of paper based materials such as paperboard. The outer surfaces are commonly printed with sales and product information. The printed carton may have a hard, clear varnish over the printing inks. While the printed information provides information to the consumer, it only conveys information based upon the design of the printing (e.g. product logo) or the data contained in the printing (e.g. marketing message, directions).
An object of the present invention is to provide a carton with printing that conveys a sensual feel to the consumer as the carton is handled.
Other objects of the present invention will become apparent to those skilled in the art by reference to the specification.
In a first aspect, the present invention is directed to a carton having multiple panels wherein at least a portion of the outer surface of at least one panel is printed with a soft feel material. This portion may be embossed, or may include the brand name and/or product logo.
In a second aspect, the present invention is directed to a carton having multiple panels wherein the complete outer surface of each panel is printed with a soft feel material.
In a third aspect, the present invention is directed to a carton having multiple panels wherein at least one panel has an embossed motif which is printed with a soft feel material.
In a fourth aspect, the present invention is directed to a carton having multiple panels wherein at least one panel has a tab that is printed with a soft feel material.
The carton of the present invention has a sensual feel and gives a sensory appeal to the packaging. The carton provides the ability to promote the perception of a soft silky feel for products which provide such a feeling such as fabric softeners, skin care products, soaps as well as other personal care products. Such a perception may also be desired in other types of products such as food products or home decoration and home care products.
By soft feel material it is meant the property of the outermost layer of the material has a Shore A or Shore D hardness (ASTM D 2240) of from about 35 to about 80, more preferably from about 35 to about 70, and even more preferably from about 35 to about 60, and including all ranges subsumed therein.

The soft feel material can be applied by conventional coating techniques. For example, in a preferred embodiment, a lacquer such as Silk Touch Lacquer 43829 commercially available from SIPCA North America is applied using gravure printing. Silk touch top varnish is applied by the offset printing process. The soft feel materials may be applied by other conventional coating techniques including, without limitation, screen printing, Thermage printing, and offset flexography.
In accordance with the invention, a soft feel material is printed on at least a portion of one panel of the carton. In another embodiment, the soft feel material may be printed on a tab of one of the panels.
The soft feel material on the carton may cover a portion of the outer surface of the carton or the entire outer surface of the carton. Preferably the soft feel material covers at least 30% of the outer surface of the carton. More preferably, the soft feel material covers at least 50% of the surface of the carton, more preferably at least 65%, and even more preferably at least 80%, and most preferably 100% of the surface of the carton, and including all ranges subsumed therein.
