[0001] In connection with the surrounding protection has particular importance the disposal
of some kinds of waste and among these the used oils. The invention refers to a high
density polythene tank particular for mineral and vegetable oils finalized to the
collecting of home used oils and to the subsequent disposal of said oils used in cooking,
in the refectories or similar. Said tank, to be provided in different dimensions and
shapes, 100% recyclable and with almost unlimited duration, has a big importance such
as it permits, after to have actuated any kind of frying, to collect and then to transport
the cooking used oils to the disposal point. For this aim a lot of tanks with particular
shapes are known, as for instance the tank described in the Italian Patent BO2003A
000623. Said tank solves the problem but it has some drawbacks that limit its use
both in case of home use than in case of no private use such as refectories, restaurants,
public locals or manifestations where is provided the distribution of foods. Infact,
the tank described in the Italian Patent BO2003A 000623, has a removable funnel only
to be placed into the oil inlet hole so creating problems during the transport and
the storage and particularly inside the home where the funnel, after the different
uses, must be separately put as to the tank body. Moreover the particular shape of
said tank body generates high production costs which are not compatible with the market
requests for example in case of public bodies that have the necessity of a low cost
product. The above cited drawbacks are solved to the production of the invented tank
that determines: a) a tank body of different dimensions and shapes but always in "cheap"
version; b) a tank body in the upper part of which, in position under the handle,
a funnel blocking system is provided that permits to the funnel to be placed and blocked
onto the tank body; and c) a tank body with a sole hole for inlet/outlet to be closed
with an anti-unscrewing plug. In particular the blocking system of the funnel onto
the tank body facilitates for the manufacturer and for the seller the storage and
transport phases such as a body more compact is created. From the point of view of
the users, instead, very important is the fact to can place quickly and steady the
funnel onto the tank so avoiding its breaking or its loss. Other characteristic is
given to the presence of the safety plug that, in particular in home situation, avoids
risks for the children. The improvements above cited are obtained with the system
and the obtained tank object of the present invention consists only of three high
density polythene components: a tank body 1, a funnel 2 and a plug 3. Said tank body
1, with an ideally rectangular shape with rounded angles, has in material continuity
an upper handle 1 A that permits the gripping of the tank and it forms a bridge structure
that is over the upper wall 1B of the tank onto which is to be placed and blocked,
in transport and no use phases, the funnel 2 upside-down. Said funnel 2, consisting
of a cylindrical body of insertion 2A and of a conical part 2B, is blocked, through
undercuts provided on the handle 1A, or relief parts provided onto the upper wall
1B, or other suitable means, to the tank body 1. This integrated blocking tank/funnel
permits to have the funnel 2 connected to the tank 1 so creating a compact unit 1,
2 advantaging to the transport point of view and in particular during the use such
as the tank 1 is full, in the major number of cases, in subsequent phases so with
the necessity to put the tank onto a shelf or inside a furniture, such as a sink.
The fundamental characteristic to have created the upper wall 1B onto which to block
the funnel 2 avoid, in relation, that the same funnel created a oneself body to must
be placed in separated position in comparison with the tank 1. The tank body then
provides, always in its upper part, a protruding cylindrical body 1C with inlet/outlet
hole for the oil to be closed with anti-screwing plug 3. Moreover the tank 1 provides,
on one or both the lateral faces, areas 1D onto which in the known ways writings of
other referring elements are reported. The blocking system, during the no use phase,
forms a compact unit 1, 2 consisting of the tank body and of the funnel whereas, in
using phase, unblocked the funnel 2 for simply manual action, possible thanks to the
elasticity proper of the plastic material, the same funnel is inserted or screwed
by means of its cylindrical body 2A into the protruding cylindrical body 1C from which
previously the plug 3 was unscrewed. Ending the pouring phase of the used oil, the
funnel 2 is cleaned and blocked again, always for manual pressure, onto the upper
wall 1B with seal given to the handle 1A. In an embodiment the funnel 2 provides,
to protect the inlet oil hole, a small sieve plate 4 that prevents to the different
impurities to go on inside the tank with the used oil. Said sieve plate 4 to be provided
in a sole body with the funnel 2 or also like an accessory to be placed into the hole
of the funnel 2. The tank 1 is to be provided in different dimensions and shapes on
the base of the different use necessities so as different are to be the blocking systems
of the funnel 2 between the handle 1A and the upper wall 1B. A preferred embodiment
of the tank to be obtained with the invented system is illustrated in a merely indicative
way in the drawing of sheets 1, 2 and 3. In sheet 1 is illustrated the tank during
the no use phase. In detail figure 1 is top view to show the funnel 2 in blocking
position onto the wall 1B. Figure 2 is lateral view of the tank/funnel unit. Figure
3 is perspective view. In sheet 2 is illustrated the tank in use phase. Figure 4 is
lateral view with the funnel in position. Figure 5 is view to the other side. Figure
6 is perspective view. In sheet 3 is illustrated the embodiment with the funnel 2
equipped with the sieve plate 4. In details figure 7 is view of the funnel with the
sieve plate in blocking position. Figure 8 is view of the funnel with the sieve plate
in use position.
