CONTAINER FOR SURPRISES, PARTICULARLY FOR CHOCOLATE EGGS

Description

[0001] The present invention relates to a container for surprises, particularly for chocolate eggs.

[0002] It is well known that containers for surprises for chocolate eggs comprise two half-shells hinged together operatively between a closed configuration and an open configuration of the container.

[0003] As such products are intended for children, it is indispensable to ensure that they can be handled in total safety without any risk of accidental swallowing.

[0004] For this reason the two half-shells are as a rule reciprocally constrained so that one cannot come detached from the other when they are handled.

[0005] The constraint between the two half-shells must however be able to permit the container to be gripped by the processing machine during the packing of the egg and the container to settle inside the egg without the latter being damaged.

[0006] One of the most widespread solutions on the market today envisages that the cylindrical lateral delimiting walls of the half-shells have, at least in the area of reciprocal hinging, weakened lines that undergo breakage once the container is opened. The break lines delimit a portion of lateral delimiting wall which, on being detached from the rest of the lateral delimiting wall, defines a longitudinal strip which keeps the two half-shells connected together even in the open configuration of the container. Document WO2007/074355 discloses a container for surprises in accordance with the preamble of claim 1. The longitudinal strip resists well to stresses of a tractional and torsional nature and thus makes it possible to have a container that is safe for the child. Safety is in fact governed by strict laws and regulations which impose compliance with minimum values of mechanical resistance to traction and/or torsion.

[0007] The drawback consists in the fact that the safety of the container is tied to its capacity to be torn and consequently, after opening, the container can no longer be correctly reused for its containing function, as its structure is irreversibly deteriorated.

[0008] The technical task the present invention has set itself is therefore to realize a container for surprises, particularly for chocolate eggs, which allows the aforementioned technical drawbacks of the prior art to be overcome.

[0009] Within the scope of this technical task, one object of the invention is to realize a container for surprises, particularly for chocolate eggs, which can be handled in total safety without any risk of accidental swallowing.

[0010] Another object of the invention is to realize a container for surprises, particularly for chocolate eggs, which can be conveniently used in a processing machine.

[0011] A last but not least object of the invention is to realize a container for surprises, particularly for chocolate eggs, which is completely recyclable and reusable.

[0012] The technical task, as well as these and other objects, according to the present invention are achieved by realizing a container for surprises, particularly for chocolate eggs, comprising two half-shells and at least one strip by means of which said half-shells are operatively connected together between a closed configuration and an open configuration of the container, characterized in that both half-shells feature a respective lateral delimiting wall having a first exterior surface portion which extends along generatrices of a cylinder and a second exterior surface portion that extends on the inside of said cylindrical generatrices, and that in the closed configuration of the container said at least one strip is superimposed on said lateral delimiting wall of both half-shells, being mainly or completely positioned within a recess present in said second exterior surface portion of said lateral delimiting wall of both half-shells.

[0013] Preferably, with reference to any section of said lateral delimiting wall orthogonal to the cylindrical generatrices of said first exterior surface portion, the thickness of the part of said delimiting wall to which said second exterior surface portion belongs is not smaller than the thickness of the part of said delimiting wall to which said first exterior surface portion belongs.

[0014] Preferably, both in the closed configuration and in the open configuration of the container, said strip is connected exclusively at the two longitudinal ends thereof to said half-shells.

[0015] Preferably, said recess extends longitudinally parallel to said cylindrical generatrices and has a constant depth.

[0016] Preferably, in the closed configuration of the container said strip extends longitudinally along said longitudinal recess.

[0017] Preferably, said strip has a flattened conformation; in an intermediate portion thereof it has a widthwise narrowing and in the closed configuration of the container it exhibits a concavity turned toward the bottom of said recess. Preferably, said strip has at least one foot for connecting to the bottom of said recess, said connecting foot being configured in such a way as to position said strip at a distance from the bottom of said recess.

[0018] Further characteristics and advantages of the invention will be more apparent from the description of a preferred, but not exclusive embodiment of the container for surprises, particularly for chocolate eggs, according to the invention, illustrated by way of non-restrictive example in the appended drawings, in which:

figure 1 shows a side elevation view of the container for surprises for chocolate eggs, in the closed configuration;

figure 2 shows a side elevation view of the container of figure 1, in the closed configuration, rotated by 90° relative to the axis of the cylindrical portions of the two half-shells;

figure 3 shows a plan view of the container of figure 1, in the open configuration;

figure 4 shows a side elevation view of the container of figure 1, in the open configuration, cut along a plane containing the axis of the cylindrical portions of the two half-shells;

figure 5 shows a perspective view of a variant of the container in which the perimeter edge of the open base of one half-shell is configured with a downwardly slanting portion to facilitate the closure between the two half-shells.

[0019] With reference to the aforementioned figures, there is shown a container for surprises, particularly for chocolate eggs, indicated overall with the reference number 1.

[0020] The container 1 comprises a first half-shell 2, a second half-shell 3 and a strip 4 by means of which the half-shells 2 and 3 are operatively connected together between a closed configuration and an open configuration of the container 1.

[0021] The first half-shell 2 features a closed base 13, an open base 14 and a lateral delimiting wall 5 having a first exterior surface portion 6 that extends along generatrices of a cylinder having an axis 8 and a second exterior surface portion 7 that extends on the inside of said cylindrical generatrices.

[0022] The second half-shell 3 in turn features a closed base 15, an open base 16 coupled with the open base 14 of the first half-shell 2 in the closed configuration of the container 1, and a lateral delimiting wall 9 having a first exterior surface portion 10 that extends along generatrices of a cylinder having an axis 11 and a second exterior surface portion 12 that extends inside said cylindrical generatrices.

[0023] With reference to any section of the lateral delimiting wall 5 of the first half-shell 2 orthogonal to the axis 8, the thickness of the part 17 of the delimiting wall 5 to which the second exterior surface portion 7 belongs is not smaller than the thickness of the part 18 of the delimiting wall 5 to which the first exterior surface portion 6 belongs. More precisely, the thickness of the part 17 is constant and slightly larger than the thickness, likewise constant, of the part 18.

[0024] Analogously, with reference to any section of the lateral delimiting wall 9 of the second half-shell 3 orthogonal to the axis 11, the thickness of the part 19 of the delimiting wall 9 to which the second exterior surface portion 12 belongs is not smaller than the thickness of the part 20 of the delimiting wall 9 to which the first exterior surface portion 10 belongs. More precisely, the thickness of the part 19 is slightly larger than the thickness of the part 20.

[0025] The exterior surface of the lateral delimiting wall 9 of the second half-shell 3 exhibits, in proximity to the open base 16, a perimeter step 21 which delimits an apical perimeter area 22 of the lateral delimiting wall 9 with a reduced thickness suitable for accommodating an apical perimeter area 23 of the lateral delimiting wall 5 of the first half-shell 2.

[0026] In the closed configuration of the container 1 in particular, the perimeter edge of the open base 14 of the first half-shell 2 goes into contact against the perimeter step 21.

[0027] The degree of the reduction in thickness of the apical perimeter area 22 of the lateral delimiting wall 9 is substantially equal to the degree of thickness of the lateral delimiting wall 5, so that in the closed configuration of the container 1, in which the apical perimeter area 23 is fitted over the apical perimeter area 22, the exterior surface of the apical perimeter area 23 is disposed on the extension of the exterior surface of the area of the lateral delimiting wall 9 adjacent to the apical perimeter area 22.

[0028] A stable mechanical attachment between the half-shells 2 and 3 in the closed configuration of the container 1 is assured by the snap coupling between a rib 24 present on the exterior surface of the apical perimeter area 22 and a groove 25 which has a shape mating with the rib 24 and is present on the interior surface of the apical perimeter area 23.

[0029] According to a salient aspect of the invention, in the closed configuration of the container 1, the strip 4 is superimposed on the lateral delimiting walls 5 and 9, being positioned mainly or completely inside a recess 26 of the second exterior surface portion 7 and 12 of the lateral delimiting walls 5 and 9.

[0030] The strip 4 is connected, at a longitudinal end 27 thereof, to the half-shell 2 and, at a longitudinal end 28 thereof, to the half-shell 3. There are no other areas of connection of the strip 4 to the half-shells 2 and 3, neither in the closed configuration nor in the open configuration of the container 1.

[0031] In the specific case, the recess 26 has a part 26a which extends longitudinally parallel to the axis 8 and a part 26b which extends parallel to the axis 11. In the closed configuration of the container 1, in which the axes 8 and 11 are coaxial, the part 26a and the part 26b are mutually juxtaposed.

[0032] The recess 26 has a flat bottom 31 and a constant depth up to the longitudinal ends thereof, one of which ends at a tapered connecting portion 29 between the closed base 13 and the lateral delimiting wall 5 of the first half-shell 2, whereas the other ends at a tapered connecting portion 30 between the closed base 15 and the lateral delimiting wall 9 of the second half-shell 3.

[0033] The strip 4 has a flattened conformation and, in an intermediate portion thereof, it has a widthwise narrowing 32 which increases its capacity to resist torsion.

[0034] In the closed configuration of the container 1 the strip 4 is superimposed, with a main face thereof, on the bottom 31 of the recess 26 and is curved in a longitudinal direction in such a way that the concavity is facing toward the bottom 31 of the recess 26.

[0035] The strip 4 exhibits a first foot 33 by means of which the longitudinal end 27 thereof is attached to the bottom of the recess 26 and a second foot 34 by means of which the longitudinal end 28 thereof is attached to the bottom of the recess 26.

[0036] In the closed configuration of the container 1 the attaching feet 33 and 34 create a space between the strip 4 and the bottom 31 of the recess 26 and are positioned at the same distance from the step 21, so that for half a length the strip 4 is superimposed on the half-shell 2 and for half a length it is superimposed on the half-shell 3.

[0037] Finally, the attaching feet 33 and 34 are dimensioned so as to be completely contained within the recess 26.

[0038] The invention offers innumerable advantages.

[0039] The container preserves its structural integrity even after being opened. It may therefore be not only recycled, if the material it is composed of is recyclable, but also reused as such by the manufacturer.

[0040] As an incentive to return the container to the manufacturer a reward can be provided, consisting for example in the supply of a free chocolate egg for every minimum quantity of containers returned to the manufacturer.

[0041] In the closed configuration, the two half-shells 2 and 3 do not have a possibility of relative rotation about the coaxially disposed axes 8 and 11 since the open bases 14 and 16 which couple together do not have an entirely circular profile. This contributes to making the closed configuration of the container 1 extremely stable. The length of the strip can be chosen at will without any particular limitations according to the capacity of mechanical resistance to torsion it is desired to impart thereto at the design stage.

[0042] The providing of a recess 26 in which the strip 4 is disposed facilitates automation of the process of packing the chocolate egg by facilitating robotized pick-up of the egg and enabling the container to settle inside the egg without the latter being able to undergo damage.

[0043] With reference in particular to figure 5, the perimeter edge of the open base of at least one half-shell, for example the perimeter edge of the open base 16, is configured with a downwardly slanting portion 35 to facilitate the closure between the two half-shells 2 and 3.

[0044] The downwardly slanting portion 35 is in a position diametrically opposite to the area where the strip 4 is provided for connecting the half-shells 2 and 3 and is formed by a cut in the face of the open base 16.

[0045] In particular, externally to the cut the perimeter edge of the open base 16 extends in a plane orthogonal to axis 11, whereas at the site of the cut the perimeter edge of the open base 16 extends in a plane that is inclined relative to the axis 11.

[0046] The downwardly slanting portion 35 speeds up the operation of manually opening the capsule to insert the toy and then closing it again and consequently implies a lower cost of labour and ultimately a lower purchase cost of the capsule.

[0047] The container for surprises thus conceived is susceptible of numerous modifications and variants, all falling within the scope of the claims. In practice, the materials used, as well as the dimensions, can be any whatsoever according to need and the state of the art.
