Abstract

An element (10) for holding and presenting confectionery products and the like, for insertion in the bottom of a box, is constituted by a sheet of card (12) defining a plurality of annular punched lines. Within each punched line, there are slits defining flaps (20, 22) which can be bent to hold the products.

Description

The present invention relates to an element for holding and presenting confectionery products, particularly chocolates and the like, which is adapted to define a plurality of seats for the products, comprising a flat sheet of card or similar material having a plurality of four-sided punchings each defined by punched lines and, within the punched lines being provided with slits, whereby said punched lines define a plurality of holes in the sheet when the flaps defined between the slits and the punched lines are bent, and comprising an auxiliary sheet arranged beneath the flat sheet and having a plurality of holes.
An element of the above type is disclosed by DE-U-89 07 594, in which the holes in the auxiliary sheet present the same dimension and form of the holes of the upper sheet in order to limit the bending of flaps. In this solution all the flaps are "floating", and in order to make the element or box more stiff it is necessary to connect the auxiliary sheet and the bottom of the box with an auxiliary bent flap glued to the bottom of the box.
The object of the present invention is to provide an element of the type specified above which is stiff and reliable without using glue or similar.
According to the invention, this object is achieved by virtue of the fact that the position of the holes on the auxiliary sheet coincide with the position of at least two opposite sides of the punchings and in which at least two corresponding opposite flaps obtained by bending said punched lines are inserted in order to keep them in an opened-out position.
By virtue of these characteristics, the card element can fulfil the same function as a thermoformed cellular element of known type, providing considerable advantages in terms of cost and environmental impact. Moreover the flaps can be snap-engaged in the holes of the auxiliary sheet, obtaining a dimensionally stable and stiff element.
Further advantages and characteristics of the holding and presentation element according to the invention will become clear from the detailed description which follows, with reference to the appended drawings, in which:

With reference to the drawings, an element for holding and presenting confectionery products is generally indicated 10 and comprises a flat punched sheet of card 12 with straight punched lines 12a and a plurality of annular punched lines 12b. These punched lines, which define lines of bending, are of the so-called half-cut type, that is, they are formed by cutting through half the thickness of the sheet 12.
With particular reference to the embodiment shown in Figures 1-4, the punched sheet 12 has a first rectangular portion A bounded by the straight punched lines 12a which are adapted to define lateral glueing flaps 14, and a second portion B which is joined to the first in correspondence with a straight punched line 15 broken by substantially U-shaped slits 16. The second portion B of the punched sheet 12 also has straight punched lines 12a adapted to define lateral glueing flaps 17 for cooperating with the lateral flaps 14 in known manner.
The annular punched lines 12b are substantially rectangular with rounded corners and are arranged in an ordered array in the first portion A of the punched sheet 12. Slits 18 are provided within each annular punched line 12b and comprise one I-shaped central portions 18a whose stems are parallel to and equidistant from the longer sides of the respective rectangular punched lines 12b, and four connecting portions 18b between the tips of the ends of the I-shaped central portions 18a and the rounded corners V of the punched lines 12b. The slits 18 and the annular punched line 12b thus define two resilient flaps 20 of card in the form of isosceles trapezia and two support flaps 22 having portions which are also in the form of isosceles trapezia and the shorter bases of which extend to form rectangular portions, indicated 22a in the drawings.
The second portion B of the punched card sheet 12 has a plurality of rectangular holes 24 arranged in positions such that, when the element 10 is assembled, they correspond to the longer sides of the rectangular punched lines 12b to which the support flaps 22 are articulated. Adjacent rectangular holes 24 are joined by shorter central portions so are generally to define substantially double-T-shaped holes 25.
When the element 10 is assembled, the second portion B of the punched sheet 12 is bent underneath the first portion A along the straight punched line 12a joining the first and second portions and along the punched line 15. During this bending, the slits 16 define support portions 27 which project downwardly so as to keep the first portion A of the sheet 12 at a constant distance from a support plane, for example, the bottom of a box. After the second portion B has been bent relative to the first portion A and the lateral flaps 14 and 17 have been glued together, the support flaps 22 and the resilient flaps 20 are bent so as to form a plurality of holes 28 in the first portion A of the punched sheet 12 defining, with the bent flaps 20 and 22, a plurality of seats S for substantially parallelepipedal products. When the support flaps 22 are bent, their rectangular ends 22a are fitted into respective retangular holes 24 so as to project below the plane of the second portion B of the punched sheet 12 (Figures 2 and 3) and have the function of forming a support on the bottom of the box. The rectangular end portions 22a of the support flaps 22 are therefore situated in the plane defined by the bent and glued flaps 14 and the support portions 27 so as to keep the frames C defined by the holes 28 in the punched sheet 12 at a predetermined distance from the lower support plane constituted, for example, by the bottom of a box.
The resilient flaps 20 "float" and, by virtue of the resilient force biassing them towards a configuration in which they are coplanar with the frames C, help to keep the products in position by eliminating the clearance between the products and the seats S. The support flaps 22, on the other hand, are kept apart by virtue of their engagement in the holes 24 in the punched sheet 12.
The embodiment shown in Figures 5-7, in which the same reference numerals are retained for similar elements, includes a third portion D of the punched sheet 12 which, in the assembled configuration, is adapted to constitute the bottom of the box. In this embodiment, therefore, the element 10 for holding and presenting the products can be used as the base of a box which can be completed by a suitable lid E, shown in broken outline in Figure 6.
Alternatively, a finished box can be produced by the superposition of two elements 10, in which one glued lateral flap 21 can be used as a hinge. In this variant, shown in Figures 8 and 9, both the base and the lid of the box have cells for the improved restraint and protection of the products.
For confectionery products of rounded shape, the variant shown in Figures 10-13 may be used to advantage. In this variant, the first portion A of the punched sheet 12 has annular punched lines 30 which are substantially square with curved sides 30a connected by rounded corners 30b. Within each punched line 30, two slits 32 arranged along the diagonals of the punched outline and a central square hole 33 define four, substantially-triangular support flaps 34 which, when the element 10 is assembled, are adapted to be inserted in corresponding holes 35 provided in the second portion B below the first portion A of the punched element 12 and arranged in correspondence with the curved sides 30a of the punched line 30. The curved lines of bending in correspondence with the punched sides 30a give the upper frame wall C of the element 10 a wavy appearance, as shown in Figure 10. Moreover, in their opened-out configuration, the flaps 34 form curved vertical walls which are adapted to fit the rounded products perfectly. The free appendages of the flaps 34 below the portion B of the punched sheet 12 act as feet and as supports for the upper frame wall C. To advantage, the element 10 of the variant of Figures 10-13 can be inserted in the bottom of a box or can be used as the base of a box if a third portion of the punched sheet is included, as described in connection with the variants shown in Figures 5-7 or 8-9.
The variant shown in Figures 14-18, although substantially similar to the solution shown in Figures 1-3, differs therefrom in that the punched element 12 does not have a second portion which can be bent but is assembled with an auxiliary sheet 40 which is glued or heat-sealed in correspondence with bent edges 42 and in correspondence with bent lateral flaps 43 of the punched sheet 12. The auxiliary sheet 40 also has a plurality of rectangular holes 44 for cooperating with support flaps 22 defined by the annular punched lines 12b and by the shaped slits 18.
The above description shows clearly the advantages of the holding and presentation element according to the invention which, by virtue of its particular characteristics, can be used not only as an accessory for a box but as an integral and structural part of the box itself.
