Laminate packaging for ice cream cones

Abstract

Of the type constituted by a laminar body, based on a paper-aluminium composition which shapes a cone (5) coincident in form and dimensions with the cone biscuit which it shall hold in its interior, having on its closing edge (6) a seam (8) of angular configuration, so that in the area immediately above this seam a tab for tearing (10) is configured which is recessed with respect to the closing edge (6). The vertex (11) of said angular seam (8) constitutes a guide which facilitates the tearing of the wrapping. Optionally, the laminar body which configures the cone (5) can come with a circumferential cutting line (15) located below the pulling flap (13), defining a tear line for the wrapping in the operation of opening the same, emerging from that circumferential cutting line (15) another cutting line (18) parallel and next to the adhesive strip (17), the purpose of this second cutting line (18) being to interrupt a possible de-layering between the paper and the aluminium, during the opening operation.

Description

OBJECT OF THE INVENTION [0001] The present invention concerns a laminar wrapping of the type of those usually employed for obtaining a cone based on a paper-aluminium composition or similar, which acts as a means of protection for the cone biscuit which in turn holds an edible ice cream. [0002] The object of the invention is to achieve a reduction in the quantity of material used in the production of the wrapping, and secondly to facilitate the subsequent opening and elimination of the same. BACKGROUND OF THE INVENTION [0003] It is well known that constituting an entirely widespread technique within the ice cream industry, specifically within the ambit of ice creams that are delivered to the customer directly packed from the maker, and more specifically within the ambit of the “cone” type ice cream in which the ice cream mass fills a cone biscuit, is the use of a wrapping based on a paper-aluminium composition, initially of triangular configuration, with one of its sides curved conv...

[0002] The object of the invention is to achieve a reduction in the quantity of material used in the production of the wrapping, and secondly to facilitate the subsequent opening and elimination of the same.

Problems solved by technology

To facilitate the subsequent operation of tearing or opening the wrapping, one of the straight edges thereof comes with a projecting tab, serving as a grip for said tearing action, which signifies a twofold problem, on one hand the presence of this tab supposes a considerable increment in the quantity of material required for the wrapping, since besides that corresponding to the tab itself, the material located at both sides of the same is lost in the stamping operation, and on the other hand the tearing of the wrapping by pulling on said tab is uncontrolled, occurring on many occasions in unwanted areas, which do not correspond to the ideal situation in which said tearing ought to take place on the periphery at a level immediately below said tab, in order to retain a small encircling cone in the area where the ice cream is held.

Moreover and as the tab mentioned projects and is physically independent of the base surface of the cone to which it is initially adapted, during the normal manipulation of the ice creams a separation frequently takes place of the same with respect to the actual cone, which on occasions can cause ripping of the actual tab or even a slight commencement in the opening of the container, affecting the sealing of the same.

Due likewise to the tight bond which the adhesive defines between the superimposed sectors of the laminar wrapping, when the detachment of the same takes place, it happens abruptly with an uncontrolled tear, which can run indistinctly toward the mouth of the wrapping or toward the vertex thereof depending on the angle of inclination with which the pulling force is applied on the tab, obtaining as a result, in either case, a completely deficient and undesirable opening.

In attempts to overcome this problem laminar wrappings are known of the type mentioned in which the closing of the laminar body is achieved by means of a continuous strip of adhesive below the tab and a discontinuous strip above it, for example based on an alignment of glued points, which does not resolve the mentioned situation in a satisfactory manner insofar as the de-layering problem remains, and it also produces a tendency to oblique tearing of the sheet toward the vertex of the cone.

Moreover, this discontinuous closure of the upper area of the wrapping signifies that the closure of the same is not totally sealed, with the consequent risk of penetration by bacteria, dirt, etc.
