Definitions

  • the present invention relates generally to packaging for food products.
  • the present invention relates to wrapper blanks, sleeves, and related manufacturing methods that may be used to make packaging for food products.
  • the present invention is particularly useful in the packaging of conical food products including, but not limited to, ice cream cones. Nevertheless, the products of the present invention may also be used for packaging of various products other than food. In addition, the products of the present invention may also be used to contain products having shapes which are not conical. Accordingly, it is believed that the patentability of the present invention is not dependent on the type or shape of the product to be contained.
  • One approach for packaging an ice cream cone novelty is to enclose it in a conical-shaped package of approximately the same angle as the baked cone.
  • the package size may be sufficiently tall to contain the entire novelty.
  • the package may be made from a wrapper blank comprised of a paper layer, a laminate structure, or other types of packaging material.
  • the wrapper blank may also include various coating layers.
  • An example of a laminate structure includes an inner paper layer that is secured to an outer foil layer.
  • the side edge portions of the wrapper blank may be heat sealed together.
  • the top of the package may be closed either by applying a separate lid or by folding the package and applying heat to activate glue at the point of the seal.
  • the package is commonly called a sleeve or jacket.
  • a top portion of the sleeve is grasped and torn off.
  • the sleeve can delaminate or otherwise separate into layers during the tearing process due to the seam joining the side edge portions of the wrapper blank. Consequently, at least a portion of an inner surface of the sleeve often remains around the ice cream cone after the initial tear. Multiple tear attempts often must be made to remove the remainder of the top portion of the sleeve from around the ice cream cone. As a result, it is often difficult or tedious to open the package. Therefore, a need exists for an improved wrapper blank, sleeve, and method of manufacturing the sleeve that will simplify the opening of a sleeved cone.
  • the present invention includes an improved wrapper blank, sleeve, and other similar or related products.
  • the present invention also includes improved methods of manufacturing the wrapper blank and the sleeve and other similar or related processes.
  • a score mark e.g., a perforation, is made on a surface of the wrapper blank. When the wrapper blank is folded into a sleeve, the score mark may be substantially parallel to the overlap seam where the side edge portions of the wrapper blank are sealed together.
  • the score mark may interrupt the delamination of the sleeve that may be caused by the seam such that the torn portion may be removed in substantially one piece. As a result, the contents of the sleeve may be accessed more easily.
  • the score mark may intersect or otherwise be used in conjunction with at least one other score mark.
  • An example of the present invention is a composite wrapper blank that is adapted to be formed into a conical shape.
  • the exemplary composite wrapper blank comprises a first layer of a foil material and a second layer of a paper material connected to the foil material.
  • the composite wrapper blank may have three principal edges: (a) a first edge which is substantially straight; (b) a second edge which is substantially straight, the first and second edges defining an angle; and (c) a curvilinear edge.
  • the composite wrapper blank may have at least two perforations: (a) a first perforation extending substantially across the angle; and (b) a second perforation extending from the first perforation along the second edge.
  • the first layer may be an exterior layer when the composite wrapper blank is formed into the conical shape.
  • a coating layer may be formed on the second layer of the paper material. The coating layer may be selected from the group consisting of waxes, clays, barrier materials, and other similar, suitable, or conventional materials.
  • the first perforation may extend from the first edge to the second edge. Also, the first perforation may be substantially parallel to the curvilinear edge.
  • the second perforation may extend from the first perforation to the curvilinear edge. The second perforation may be substantially parallel to the second edge. Furthermore, the second perforation may be substantially perpendicular to the first perforation.
  • the first perforation and the second perforation may each be made in the first layer substantially without puncturing the second layer.
  • the first perforation and the second perforation may each be made in the second layer substantially without puncturing the first layer.
  • the perforations may puncture both the first and second layers, if desired.
  • Another embodiment of the present invention is a conical sleeve.
  • the conical sleeve may include any of the optional or preferred features of the above- described composite wrapper blank.
  • the conical sleeve comprises a tip and a top edge.
  • a lateral side extends between the tip and the top edge.

Abstract

L'invention concerne un manchon pour aliment conique. L'invention concerne également un papier d'emballage et plusieurs procédés de fabrication. Un procédé de fabrication consiste à faire un tracé, tel qu'une perforation, par exemple, sur la surface d'un papier d'emballage. Lorsque l'on plie le papier d'emballage pour former un manchon, ledit tracé peut être disposé parallèlement à la jonction de recouvrement au niveau de laquelle les bords latéraux du papier d'emballage sont collés ensemble. Ledit tracé permet d'éviter la délamination du manchon qui peut être due à la jonction, lorsque l'on déchire une partie du manchon pour accéder au contenu du manchon, tel qu'un cornet de glace, par exemple. La partie déchirée peut être ainsi enlevée en une seule pièce, ce qui permet d'accéder plus facilement au contenu du manchon. Pour faciliter davantage le processus d'ouverture, le tracé peut croiser au moins un autre tracé ou être utilisé conjointement avec au moins un autre tracé.
