[0001] The present invention refers to a container made of plastic material for funeral
use, and in particular to a counter-coffin made of plastic material per funerary coffin
or to an internal container made of plastic material of a cinerary urn.
[0002] The art proposes a great number of containers for funerary use for containing mortal
remains and ashes of dead people, mainly made, depending on their specific use, as
counter-coffins for coffins or internal containers of cinerary urns.
[0003] As known, a funerary coffin adapted to contain therein a corpse is generally composed
of a coffin made of wooden material and of a counter-coffin made of zinc. The wooden
coffin can indifferently be internal or external to the metallic coffin even if, due
to aesthetic reasons, it is commonplace to arrange it externally: in this latter case,
the corpse is obviously arranged inside the zinc coffin, generally called counter-coffin.
[0004] The metallic coffin must then be airtight closed through a welding (cold welding
is also used, in addition to fire welding) that is continuous and extended on the
whole periphery of the contact area of the elements to be welded.
[0005] In general, anyway, the materials to be used for building containers suitable for
transporting corpses must ensure the mechanical resistance for the necessary support
of the body and the tightness of the coffin, in order to prevent odours or organic
liquids from going out of the coffin. For such purpose, the obvious needs of sturdiness
of the coffin capable of offering more guarantees about the bier tightness and that
would require the use of certain types and thickness of used materials, go against
the further needs that require opposite characteristics: in fact, for example, the
coffins aimed to inhumation or cremation should, on the contrary, be made with minimum
thickness and soft wooden essences, that can be easily biodegraded and/or burnt. In
particular, the same use of zinc for making the metallic counter-coffin creates numerous
inconveniences. In fact, it requires, in case of cremation, the use of high temperatures
inside the oven and generates, following the combustion, ashes e residuals that can
be managed with difficulty, since they can ruin the refractory material of the oven
itself.
[0006] Moreover, in case of inhumation, the zinc coffin is a cemetery waste that can be
disposed of with difficulty.
[0007] Moreover, the welding operation of the cover of the zinc counter-coffin is cumbersome,
generating vapours that are inhaled by the responsible operator. Moreover, since such
operation is performed manually, sometimes the welding bead is not performed skilfully
and has discontinuities that can make passageways for odours and organic liquids,
strongly impairing the necessary airtight seals required for the coffin.
[0008] The art has also proposed containers made of plastic material for transporting corpses,
like those disclosed in
EP1702602,
US5301398,
DE102004020543,

US5301398.
[0009] Such known containers however are generally aimed for an emergency use in the field,
for example in case of severe natural disasters or war conflicts that cause a high
number of victims, in order to allow the removal of great numbers of corpses in a
short time, using such temporary containers that are cheaper and more easily adapted
to be transported with respect to traditional coffins. In such context, therefore,
the realisation of known plastic containers does not solve the specific problems of
which plastic material is more suitable to make a container whose use is not only
temporary, but that must comply with the strict law requirements imposed by various
national standards pertaining to the construction characteristics for coffins and
to the cautions for funereal transports.
[0010] The art further proposes caissons made of plastic reinforced by fibre glass or other
material that can be easily disinfected, in which a coffin only made of wood can be
laid during its handling, in order to guarantee a perfect seal during transports,
due to hermetic gaskets with which such caissons are equipped.
[0011] A cinerary urn, typically made of the most various materials such as granite, marble,
etc., is instead adapted to house therein a zinc container, equipped with a cover
made of the same material, containing the ashes obtained from the cremation of a corpse.
[0012] The zinc container must then be airtightly sealed by welding the cover (the cold
welding is also used, in addition to the fire welding) continuously and extensively
along the whole periphery of the contact area of the elements to be welded.
[0013] In time it has been detected how the zinc container of the cinerary urns is a cemetery
waste that is difficult to dispose of. As answer to such problem, the art has proposed
cinerary urns made of biodegradable material, like those disclosed in
HU3463,
KR100858332,
EP1588684,
CN2500294,
JP2000000277,
DE19744331,
JP10165463,
DE4204404: the realisation of such known containers however does not solve the specific problems
of which plastic material is most suitable for making a container whose use is not
only for environmental protection purposes, but that has adequate features of sturdiness,
stiffness and airtight seal.
[0014] Moreover, the welding operation of the cover of the internal zinc container is cumbersome,
generating vapours that are inhaled by the responsible operator.
[0015] Therefore, object of the present invention is solving the above prior art problems
by providing a container made of plastic material for funeral use, and in particular
a counter-coffin made of plastic material for funerary coffin or an internal container
made of plastic material of a cinerary urn, that is more practical, cheaper and lighter
than the similar containers for funerary use of the prior art.
[0016] Another object of the present invention is providing a container made of plastic
material for funeral use, and in particular a counter-coffin made of plastic material
for funerary coffin or an internal container made of plastic material of a cinerary
urn, that has the features of sturdiness, stiffness and airtight seal required by
the standards and the similar containers for funerary use of the prior art.
[0017] Moreover, an object of the present invention is providing a container made of plastic
material for funeral use, and in particular a counter-coffin made of plastic material
for funerary coffin or an internal container made of plastic material of a cinerary
urn, in which the welding of the cover is easier and quicker, guaranteeing a maximum
airtight seal.
[0018] Another object of the present invention is providing a container made of plastic
material for funeral use, and in particular a counter-coffin made of plastic material
for funerary coffin, that can be easily ignited in case of cremation, reducing the
required combustion heat and removing the production of ashes that can be managed
with difficulty.
[0019] The above and other objects and advantages of the invention, as will result from
the following description, are obtained with a container made of plastic material
for funeral use, and in particular a counter-coffin made of plastic material for funerary
coffin or an internal container made of plastic material of a cinerary urn as claimed
in claim 1. Preferred embodiments and non-trivial variations of the present invention
are the subject matter of the dependent claims.
[0020] It will be immediately obvious that numerous variations and modifications (for example
related to shape, sizes, arrangements and parts with equivalent functionality) can
be made to what is described, without departing from the scope of the invention as
results from the enclosed claims.
[0021] The present invention will be better described by some preferred embodiments thereof,
provided as a nonlimiting example, with reference to the enclosed drawings, in which:
- Figure 1 shows a side and exploded perspective view of a funerary coffin equipped
with a preferred embodiment of the counter-coffin made of plastic material according
to the present invention;
- Figure 2 shoes an enlarged view of the detail in box A of the counter-coffin made
of plastic material of Figure 1; and
- Figure 3 shows a side and exploded perspective view of a cinerary urn equipped with
a preferred embodiment of the internal container made of plastic material according
to the present invention.
[0022] With reference to the Figures, it is possible to note that a preferred embodiment
of the container for funeral use 1 according to the present invention is composed
of at least one lower container 3 and of at least one cover 5 that can be superimposed
to such lower container 3, such container 3 and such cover 5 being made of a plastic
material.
[0023] In a preferred embodiment thereof, as shown for example in Figures 1 and 2, the container
for funeral use 1 according to the present invention is a counter-coffin adapted to
be preferably arranged inside a funerary coffin according to the prior art composed
of a coffin 4 and of a related cover 6, such lower container 3 being then adapted
to contain therein a corpse.
[0024] In a preferred alternative, as shown for example in Figure 3, the container for funeral
use 1 according to the present invention is an internal container adapted to be preferably
arranged inside a cinerary urn according to the prior art composed of a vase 8 and
of a related cover 10, such lower container 3 being then adapted to contain therein
the ashes of a corpse.
[0025] Depending on resistance and stiffness tests made by the Applicant, it resulted that
the above plastic material is preferably a thermosetting material. Still more preferably,
such thermosetting material is polyethylene, and in particular a Low Density Poly-Ethylene
LDPE, and still more preferably reticulated polyethylene. Possibly, it is possible
to provide for an increase of the structural characteristics of the above material
by adding suitable charges or additives.
[0026] The above thermosetting material for making the container for funeral use 1 according
to the present invention in fact allows obtaining the following advantageous characteristics
with respect to other plastic materials:
- better shape stability;
- better stiffness;
- change of heat-welding;
- cremation temperature lower than the zinc one, lower ashes and residuals being produced
and lower fuel consumption in case of container for funeral use 1 used as counter-coffin.
[0027] In fact, differently from what has been proposed by the prior art, the Applicant
has dealt with a previously neglected problem, by experimentally selecting among the
numerous types of known plastic materials those that are better suited for producing
a container for funeral use 1, evaluating as suitable for the examined application
the following other families of plastic composites for the following reasons:
- PVC: it frees HCl in case of combustion;
- polystyrene: excessive stiffness and too high glass temperature, production of toxic
fumes during combustion;
- polypropylene: it does not reticulate or reticulates with difficulty apart from when
added with additives;
- High Density Poly-Ethylene HDPE: it reticulates with difficulty.
[0028] Obviously, the production methods for the container for funeral use 1 according to
the present invention are several and substantially belong to the known prior art.
In general, anyway, the container for funeral use 1 according to the present invention
advantageously allows the easy and cheap production of the related container 3 and
cover 5 made in a single piece in the above thermosetting material through simple
stamping workings.
[0029] Although it is clear that, even only for simplifying the production processes, the
container 3 and the cover 5 are made in the same above material, nothing prevents
that, where this is necessary or required by particular structural and/or legal needs,
they are, on the contrary, made differently with two different thermosetting materials,
without therefore departing from the scope of the present invention.
[0030] Obviously, welding of the cover 5 on the container 3 can occur according to any known
technique, for example through poly-fusion heat-welding plates or heat-welding pliers
and/or beads of adhesive or two-component material. In a preferred embodiment of the
container for funeral use 1 according to the present invention like the one shown
in particular, for example, in the Figures, the container 3 is however equipped with
at least one perimeter edge 7 corresponding to a similar perimeter edge 9 of the cover
5, such edge 9 being overlapped to the edge 7 of the container 3 upon placing the
related cover 5 onto the container 3 itself. Along such edge 7 and/or 9, then resistor
heat-welding means are arranged, suitable to at least partially melt the plastic material
of which such edges 7, 9 are made and to mutually weld them. In a first preferred
embodiment thereof, the resistor heat-welding means are integrated into the container
for funeral use 1 according to the present invention and are preferably made as at
least one electric resistance filament 11 suitably immersed into the plastic material
of the edge 7 and/or 9 or arranged on the surface along such edge 7 and/or 9, such
electric resistance filament 11 having its two electric terminals 13 going out of
such edge 7 and/or 9 adapted to be connected to a source of electric energy, such
as for example a generating set, an electric battery or, simply, suitably modulated
mains current, and supplied with current upon welding. In this case, in order to proceed
then with the heat-welding of the cover 5 onto the container 3 in a practical and
quick way, it is enough to place the cover 5 onto the container 3, by overlapping
the related edges 7, 9, and to supply with current the electric resistance filament
11 by connecting its own electric terminals 13 to the source of electric energy, for
example by means of normal electric terminals. Heating by dissipation of electric
power of the electric resistance filament 11 then generates the at least partial melting
of the plastic material of the edges 7 and 9 in contact, and the related heat-welding
between these latter ones. Obviously, the continuity with which the electric resistance
filament 11 is arranged along the edge 7 and/or 9, making for example a serpentine
to increase the heat exchange surface between filament 11 and plastic material of
the edges 7, 9, guarantees the actual continuity and homogeneity of the welding and
the necessary airtight seal of the container for funeral use 1 according to the present
invention.
[0031] In another preferred embodiment thereof (not shown), the resistor heat-welding means
are external to the container for funeral use 1 and are made as at least one electric
resistance filament coated with at least one layer of polyethylene, at least one of
such edges 7 and/or 9 being equipped on its perimeter with at least one groove suitable
to house therein such filament upon heat-welding the cover 5 onto the container 3.
Obviously, such coated electric resistance filament has electric terminals suitable
to allow the connection to the source of electric energy.
[0032] In this case, in order to proceed with heat-welding the cover 5 onto the container
3, it is enough to place the coated electric resistance filament inside the groove
of the edge 7 or 9 and to overlap the cover 5 to the container 3. By supplying with
current the coated electric resistance filament through its own electric terminals
connected to the source of electric energy, heating by dissipation of electric power
of the electric resistance filament generates the melting of its own coating made
of polyethylene and the related heat-welding between the edges 7 and 9. Obviously,
also in this case, there is a continuity with which the coated electric resistance
filament guarantees the actual continuity and homogeneity of the welding and the necessary
airtight seal of the container for funeral use 1 according to the present invention,
such continuity being determined by the shape and development of the groove.
