Definitions

  • the present invention relates to a container, destined in particular for the packaging of solid ice confectionary products, such as waterice or the like.
  • a known packaging for the above mentioned products includes an envelope of paper-like material wherein the waterice or the like is contained, provided with a stick to be grasped extending integrally from its base. At the moment of consumption, the product; completely freed from its envelope, is carried to the mouth by grasping said stick.
  • Another more recent kind of packaging includes a tubular envelope made with a suitable relatively rigid material, having a closed bottom and an upper delivery mouth which is closed after the filling of said envelope with the product in question, for the consumption of which it will be necessary to open said delivery mouth through which the product is gradually pushed out of the envelope by exerting a compression action on the latter.
  • FIG. 1 Another further kind of packaging is also known (US-A-4657142), which comprises an envelope having a closed bottom, an upper aperture which is closed after filling of said envelope with the product to be eaten, as well as removing means for removing by tearing an upper part of the container from the remaining part of the container.
  • US-A-4657142 comprises an envelope having a closed bottom, an upper aperture which is closed after filling of said envelope with the product to be eaten, as well as removing means for removing by tearing an upper part of the container from the remaining part of the container.
  • Even such packaging shows limitations and drawbacks: in particular the panels of its blank only allow a container having a final shape of a very flattened cone to be obtained, thus strictly limiting kinds and forms of products to be inserted within the envelope, on one hand, and rendering it difficult gradually to push the product out of the envelope through a compression action on the latter, on the other hand; moreover this packaging is rather complicate as to its starting material and its assembling.
  • the object of the present invention is to provide a container, in particular for waterice or the like, having a very simple structure, obtained in a three-dimensional form starting from a single-piece flat blank or punched member which, in the completely sealed condition is extremely effective for a hygenic packaging and-protection of the above mentioned product and is such as to allow, in the open condition, a trouble-free gradual consumption of the product itself without danger of soiling or other.
  • Another object of the present invention is to provide a container of the above mentioned kind provided with tear-open means from the completely sealed condition.
  • the punched member generally shown in 1, made of paper-like material, substantially rigid and substantially flexible, and treated for impermeabilization, for instance polyethylene coated so as to impart to it characteristics of heat welding, includes in a central position a panel 2 having the shape of a trapezium having each of the non parallel sides united through a crease line to a side of a respective panel 3 and 4 constituting the side wall and having the shape of an isosceles triangle, the opposite side of each of which is connected by means of a crease line to one of the non-parallel sides of a respective half-panel 5, 6 of the front wall, having the shape of a trapezium.
  • the greatest base of the trapezium shaped panel 2, the bases of the triangular panels 3 and 4 and the greatest bases of the trapezium shaped panels 5, 6, which constitute the contour of the upper opening of the container in question following its assembly into a threedimensional form, are connected by means of crease lines to long sides corresponding to the respective substantially rectangular flaps 7, 8, 9, 10 and 11 which limit said upper opening of the container.
  • the punched member formed in this way has, in a position lying between the top and bottom ends of said panels, two reduced strengh lines 12 and 13 spaced from one another, constituted by a double sequence of segments obtained on each of said panels, in a relationship which is parallel to each other and to the respective bases of said panels.
  • a tear tab 14 having a width equal to the distance existing between the two reduced strength lines 12 and 13 and positioned as a continuation of these, extends integrally from the side of the panel 5 opposed to that of connection to panel 3.
  • the assembly of the container according to the present invention in its three-dimensional form is performed as follows: the half-panels 5 and 6 are folded at right angles with respect to the panels 3 and 4 along the respective connection crease lines so as to overlap a portion of the longitudinal free edge of the panel 5 over the corresponding portion of longitudinal free edge of the panel 6, said overlapping entailing moreover the overlapping of the corresponding portions of the flaps 10, 11; said overlapped edge portions of the panels 5, 6 and of the flaps 10, 11 are sealed in watertight manner, for instance by thermal welding if this is allowed by the starting material, without, obviously, involving in said sealing the tear tab 14; then the closed bottom is formed, indicated in 19 in the figures 2-6, by a watertight sealing one with the other of the lower terminal portions of the panel 2 and of the whole constituted by the two half-panels 5 and 6 made integral as previously disclosed.
  • the container according to the present invention assembled in its three-dimensional form, is shown in its open condition in figures 2, 3 and 4, where it is generally shown in front elevation, side elevation and rear perspective, respectively.
  • the tight closing of said opening is performed by exerting a pressure on the portions of the panels 3 and 4 included between the crease lines 15, 16 and 17, 18, respectively, with the consequent folding inwards along said pairs of crease lines of the first, second, third and fourth triangular portions 19, 20, 21 and 22 until bringing the first two into contact with the correspondign portions of the half-panel 5 and of the half-panel 5, respectively, as well as into contact with each other and the second two into contact with the corresponding portions of the panel 2 and of the half-panel 6, respectively, as well as also these into contact with one another, the above entailing the foldover of the flaps 8 and 9 and the adhesion of the respective halves, as well as the adhesion of the flap 7 to the flaps 10 and 11, the latter having been fastened to one another as previously said.
  • the sealing is effected, for instance by thermal welding if the material is such as to allow such procedure, of the abutting half of each of the flaps 8 and 9, as well as of the flap 7 with the integral whole of the flaps 10 and 11, obtaining in this way the container of the present invention which is completely watertightly closed and which appears as shown in front perspective in figure 5.
  • the container is held grasped in one hand, grasping it under the second reduced strength line 13, and with the other hand one grasps the tab 14, then exerting on it a tear away action in such a way as to take away, with relative ease because of the presence of the reduced strength lines 12 and 13, the peripheral strip included between said reduced strength lines, thus separating the upper part, extending above the reduced strength line 12, from the lower part, extending below the reduced strength line 13, and, while the former will be eliminated, the latter will perform the function of support of the contained product which will conveniently protrude out of its upper opening, defined by the reduced strength line 13, to be easily consumed, as shown in figure 6 in which said product is an ice cream 24, partially consumed.
