Definitions

  • the present invention relates to a package for a food product and a method for obtaining the package.
  • a package for food product is known on the market, in particular for a cheese which is packaged in the molten state and then used by the consumer in solid condition, wherein the package comprises a stick for supporting the solid product to be consumed and wherein the package for containing the product comprises two opposite shells, made of material that can be peeled to favour the release of the contained product, which are joined to each other along the perimeter of mutual contact fully encompassing in their interior both said food product and the support stick.
  • the aforesaid package is obtained through a procedure wherein said package is realised in such a way that it comprises an ample chamber for housing the food product and a blind recess, in communication with said chamber, defining a seat within which said support stick is inserted, before pouring the food product inside said container.
  • a drawback present in this known package relates to the fact that, during the pouring of the product in molten or liquid condition, part of the material can reach the stick inside its seat defined by the blind recess, fouling and encrusting the stick itself. The result is a very disagreeable situation for the consumer who upon eating the cheese itself sustains the product by holding it from the stick and hence unpleasantly dirties the hand with which he/she holds the package.
  • the invention provides a package having the characteristics of claim 1 , in particular a package for a food product, the package comprising a container defining an inner chamber, a food product housed in said inner chamber of said container; the package being characterised in that said container presents a through opening which opens outwards and into said housing chamber, in that it comprises a longitudinally hollow tubular element associated to the package in such a manner as to present a longitudinal portion, terminating an free extremity, which extends from said container, and in that said tubular element is associated to the package in correspondence with said through opening of said container.
  • the tubular element realising on each occasion either a support element or a suction straw, presents, extending to the outside of the container, the grip portion for the consumer's hand or mouth which is clean and not fouled with the packaged material as took place instead with the products of the prior art.
  • the present package it is possible to use a single procedure and thus a single machine, implementing said procedure, to obtain the packaging of consumable products both in the solid condition, such as cheese, chocolate, jam and ice cream, and in the liquid condition, such as yoghurt and beverages in general.
  • the invention further relates to a method to realise said package according to claim 33.
  • a method for realising a package of a food product providing for readying a container having a housing chamber for said product, and to introduce the product, in substantially liquid condition, inside said housing chamber of the product, the method being characterised in that it provides said container with a through opening which opens towards the exterior of the container and into said housing chamber; and in that, before said product introduction phase, a longitudinally hollow tubular element is associated in correspondence with said opening, and in that the introduction of the product, in substantially liquid condition, inside said housing chamber is effected by letting the product pass through said longitudinally hollow tubular element.

  • the container is maintained vertical and the product in liquid or viscous condition enters by injection within the respective chamber of the package.
  • the product in liquid condition is made to pass through the cavity 29 of the tubular element 24, accumulates starting from the bottom of the housing chamber 14 and rising therein it progressively expels the air contained inside said chamber 14.
  • the ascent of the food product in liquid condition into said tubular element can be favoured through the use of a tubular element 24 that provides for a certain capillarity effect which attracts upwards the viscous product 16.
  • a sealing closure phase of said container is provided, with the product inserted into said chamber of the container by means of closure of the axial passage of said tubular element.
  • Said closure is effected, as shown in Figure 16 relating to a cross section view of the blister, closing said tubular element 24, in correspondence with the free extremity of said projecting portion 26 of said tubular element, by means of a mutual sealing 30 of the opposite edges of said tubular element 24. Said seal being obtained thanks to the sealing elements 252 which mutually compress the part to be sealed of the tubular element.
  • the method described herein is applicable in a wholly similar manner also to obtain the second embodiment shown, with the variation of not providing a seal between shells that presents detached contact parts to define the aforementioned gripping and pulling portions which serve to separate the shells, that are expressly provided for the package of the solid product, and the additional variation of feeding longer tubular elements, presenting a pre-formed weakening line for opening the package and for using the tubular element as a straw for the intake of the packaged liquid product.
  • a single apparatus realising the present method allows to obtain, with modest modifications, both packages for a product, to be consumed solid, provided with an appropriate handle or support stick, and packages for liquid or semi-liquid products to be consumed through suction by means of an appropriate straw.
  • a further advantage is given by an elongated tubular element extending into and outside of the container, possibly even only inside and outside the container itself, which also allows to introduce the material in liquid condition into the inner chamber of the container with controlled flow and lesser turbulence, thereby obtaining, among other advantages, a reduced formation of bubbles or enclosure of air in the product.
  • the fact that the package is filled through a tubular element destined to constitute a support stick or a suction straw further allows to provide a single hole in the package, thereby attaining advantageous work process economies.

Abstract

La présente invention concerne un emballage pour produit alimentaire. Cet emballage (10) est constitué d'un contenant (12) définissant une chambre interne (14) recevant un produit alimentaire retenu dans cette chambre (14). L'emballage comporte un élément tubulaire creux (24) associé à l'emballage (10) et dont un segment (26) se termine par une extrémité libre dépassant du contenant (12) et servant de poignée ou de chalumeau. Pour réaliser l'emballage on commence par réaliser un contenant (12) définissant une chambre (14) destinée à recevoir le produit (16). Puis on réalise un canal traversant (22) mettant en communication l'extérieur et l'intérieur de la chambre (14). Le procédé consiste ensuite à introduire le produit à l'état sensiblement liquide à l'intérieur de la chambre après avoir équipé d'un élément tubulaire creux (24) le canal traversant (22). Il ne reste plus, dès lors qu'à introduire le produit (16) à l'état sensiblement liquide à l'intérieur de la chambre (14) en le faisant fait passer par l'élément tubulaire creux (24).
