DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) Referring now to the annexed drawings, reference numeral 1 designates as a whole a container for waste collection, in particular for differentiated waste collection, according to the present invention.

(7) The container 1 according to the present invention comprises a containment body 10, within which there is at least one collection compartment 20, said containment body 10 being provided with at least one top opening 30 for delivering waste into said collection compartment 20.

(8) The container 1 comprises also a door 40 movably connected to the containment body 10 for selectively opening or closing said opening 30 and allowing or inhibiting access to the collection compartment 20.

(9) The container 1 according to the present invention is of the type intended to be emptied from below, i.e., of the type comprising at least one load opening 30, for depositing the waste into the collection compartment 20, in the upper part of the containment body 10, while the waste can be removed from the collection compartment 20 of the container 1 through another opening (not shown in the annexed drawings, since it is of a known type) provided in the bottom part of the containment body 10.

(10) Generally, containers of this type (to be emptied from below) are bell-shaped or have a quadrangular and/or rectangular cross-section. In the case of the container 1 according to the present invention, the containment body 10 has a quadrangular cross-section with rounded angles, wherein the area of said quadrangular cross-section decreases starting from the bottom part or base of the containment body 10 towards a top wall 10S of said containment body 10; as a consequence, the shape of the containment body 10 resembles a truncated cone with rounded or smoothed angles.

(11) Furthermore, the body 10 of the container 1 according to the present invention consists of a shell that may be made as one suitably shaped element or, alternatively, as a given number of shaped (e.g., by moulding) components joined together through the use of various methods known in the art (e.g., screws, rivets, welding, spot welding, etc.).

(12) The container 1 comprises coupling means 2 that permit coupling said container 1 to a hooking device, which is usually carried by a motor vehicle and is adapted to hook and lift the container 1 in order to empty the collection compartment by causing the waste to fall through the additional opening provided in the bottom part of the containment body 10; it should be noted that the motor vehicle and its hooking device are not shown in the annexed drawings.

(13) In a preferred embodiment, said coupling means 2 comprise a cylindrical bushing with one end firmly fixed to a top wall 10S of the containment body 10 of the container 1; as is particularly visible in FIGS. 3 and 4, the container 1 also comprises actuation means (designated as a whole by reference numeral 3 in such figures) associated with the cylindrical bushing 2, which are preferably positioned inside the containment body 10 of said container 1, said actuation means 3 being adapted to allow opening and/or closing at least one door associated with an opening in the bottom part of the container 1. Preferably, said actuation means 3 are substantially correspondent to those disclosed in European patent No. EP1172308B1 in the name of the present Applicant, the contents of which shall be deemed to have been fully incorporated in the present description.

(14) The container 1 according to the present invention further comprises a mask 50 (visible in FIGS. 2, 3 and 4) interposed between the collection compartment 20 and the door 40 when said door 40 is in a first operating condition in which it closes the opening 30 (as shown in FIGS. 1 and 3), said mask 50 comprising at least one mouth 51 for delivering waste into the collection compartment 20. Said at least one mouth 51 may have a rectangular, square or circular section, or may be shaped according to the dimensions and shapes of the waste to be delivered through it; moreover, the dimensions of said at least one mouth 51 are such as to allow the introduction of specific waste into the collection compartment 20.

(15) The mask 50 extends along the entire surface extension of the opening 30.

(16) It must be pointed out that the mask 50 may be so realized as to comprise a plurality a mouths 51; in such a case, the mouths 51 may all be substantially equal (such a configuration being particularly appropriate when the container 1 is intended for one type of waste only), or each mouth 51 may differ from the other ones (such a configuration being particularly appropriate when the container 1 is intended for different types of waste and/or when the collection compartment 20 is divided into different sections intended to receive different types of waste).

(17) The provision of a mask 50 provided with a plurality of mouths 51 makes it possible, therefore, to condition the waste delivery according to the types of waste indicated by the mask 50, and also to optimize the distribution of the waste inside the collection compartment 20, since the provision of multiple mouths 51 prevents the waste from being deposited by the user always in the same areas of the collection compartment 20, which would create an undesired accumulation of waste in a same area of the collection compartment 20.

(18) In accordance with the present invention, said mask 50 is permanently fixed to the containment body 10 in such a way that it defines a slit 50F between an upper edge 50S of said mask 50 and the containment body 10, said slit 50F being adapted to permit the passage of the door 40.

(19) In substance, the mask 50 is fixed to the containment body 10 in such a way that it cannot move relative to said containment body 10, since it is provided with side edges and/or a bottom edge firmly secured to the containment body 10, while the top edge 50S of the mask 50 is spaced apart from the containment body 10 and is not constrained to said containment body 10, so as to define said slit 50F that permits the passage of the door 40.

(20) Finally, in accordance with the present invention the door 40 is constrained to the containment body 10 by actuation means (designated as a whole by reference numeral 60 in the annexed drawings) that comprise at least one pin 61 adapted to rotate about a substantially horizontal axis relative to the containment body 10, so as to allow said door 40 to alternately switch: from a first operating condition in which it closes said at least one load opening 30, wherein the door 40 is positioned externally relative to the mask 50 (as shown in FIGS. 1 and 3); to a second operating condition in which it opens said at least one load opening 30, wherein the door 40 is positioned internally to the collection compartment 20 (as shown in FIGS. 2 and 4), in particular in said second operating condition said door 40 being positioned under a top wall 10S of the containment body 10.

(21) As can be seen in the sectional side view of FIGS. 3 and 4, the actuation means 60 comprise a connection element 62 having a first portion 62A constrained to the door 40 and a second portion 62B constrained to the pin 61, so that the rotation of said pin 61 about said substantially horizontal axis is such as to allow said door 40 to follow a trajectory shaped as an arc of circumference both when switching from the first operating condition to the second operating condition and when switching from the second operating condition to the first operating condition. For example, said connection element 62 may consist of a bracket or a similar element.

(22) In particular, the first portion 62A of the connection element 62 is constrained to the door 40 in proximity to an upper end 40S of said door 40; in this regard, it should be noted that said upper end 40S is that end of the door 40 which is closest to the top wall 10S of the containment body 10 when the door 40 is in the first operating condition in which it closes said at least one load opening 30 (i.e., in the position shown in FIG. 3).

(23) The connection element 62 is preferably associated with balancing means 63 that allow balancing the assembly consisting of the door 40 and the actuation means 60 during the movement of said door 40 from the first closed operating condition to the second open operating condition, and vice versa.

(24) In the embodiment shown in FIGS. 3 and 4, said balancing means 63 comprise a counterweight constrained to an extension 62C of the connection element 62, in particular said extension 62C developing from the second portion 62B in a direction opposite to the position of the first portion 62A of the connection element 62.

(25) It is however clear that the balancing means 63 may also be realized in a different manner; by way of example, said balancing means 63 may comprise an elastic element (not shown in the annexed drawings, which may consist of a coil spring) having a first end constrained to the connection element 62 and/or to the pin 61 and a second end constrained, whether directly or indirectly (e.g., through linking elements), to the containment body 10.

(26) In a preferred embodiment, the door 40 has an arched shape in a lateral cross-section, i.e., when viewed as in the sectional view of FIGS. 3 and 4.

(27) Preferably, said at least one opening 30 comprises at least one lateral edge provided with a guide 31 (visible in FIG. 4) adapted to receive the lateral portions of the door 40 and guide the movement thereof from the first closed operating condition to the second open operating condition, and vice versa.

(28) Said guide 31 has a shape substantially matching the shape of the lateral section of the door 40 and of the lateral portions thereof; as a consequence, in the preferred embodiment in which the door 40 has an arched shape in a lateral cross-section, also the guide 31 has an arched shape.

(29) The container 1 according to the present invention may then comprise at least one damping element (not shown in the drawings) connected to the door 40 and/or to the actuation means 60 to slow down, in at least one tract, the movement of the door 40 from the second open operating condition to the first closed operating condition and/or the movement of the door 40 from the first closed operating condition to the second open operating condition. Said damping element may consist of a piston, an actuator or a similar element.

(30) It should also be noted that the container 1 may comprise a handle 41 constrained to the door 40 and/or a pedal bar 11 connected to the door 40 and/or to the actuation means 60, wherein by actuating said handle 41 and/or said pedal bar 11 it is possible to move the door 40 from the first closed operating condition to the second open operating condition, and vice versa.

(31) The container 1 according to the present invention may then comprise locking means (not shown in the drawings) adapted to hold the door 40 firmly locked with respect to the containment body 10 in said first closed operating condition.

(32) For example, said locking means may comprise a lock (preferably of the mechatronic type) associated with a control unit to allow unlocking the door 40 upon recognition, by said control unit, of an identification code of a user authorized to deliver waste into said container 1.

(33) The features of the present invention, as well as the advantages thereof, are apparent from the above description.

(34) In particular, an important advantage of the container 1 according to the present invention lies in the fact that the provisions concerning the door 40 allow providing a container 1 for waste collection which is so realized as to minimize the user's discomfort, effort and involvement during the operations necessary for depositing the waste and during the operations necessary for positioning such waste inside a suitable container 1.

(35) In fact, the particular provisions concerning the door 40 permit the user to deliver waste only by moving said door 40 from the first operating condition in which it closes said at least one opening 30 to the second operating condition in which it opens said at least one opening 30, and vice versa, such movement of the door 40 being accomplished by activating actuation means 60 which constrain the door 40 to the containment body 10, and which comprise a pin 61 adapted to rotate about a substantially horizontal axis relative to the containment body 10.

(36) A further advantage of the present invention lies in the fact that the particular provisions concerning the door 40 and the actuation thereof make it possible to ensure a high level of hygiene, especially near the waste load opening 30; in fact, the peculiar provisions concerning the door 40 and its actuation means 60 make it possible to position the door 40 internally to the collection compartment 20 and under a top wall 10S of the containment body 10 when it is moved into the second operating condition in which it opens said at least one load opening 30, i.e., when waste needs to be introduced. It is apparent that such provisions prevent the door 40 from coming in contact with and being eventually soiled by the waste, thus ensuring decency of both the container 1 according to the present invention and the area where it has been positioned. Furthermore, such provisions provide access to the collection compartment 20 for depositing waste therein without the door 40 requiring much space in order to be opened and closed, unlike prior-art devices wherein the door 40 must be turned about a hinge in order to be opened and closed.

(37) A further advantage deriving from the peculiar provisions concerning the door 40 and the actuation thereof lies in the fact that, in the second operating condition in which it opens said at least one load opening 30, the door 40 is positioned internally to the collection compartment 20 and under a top wall 10S of the containment body 10, and therefore is not in a position in which it can limit or reduce the available waste collection volume inside the collection compartment 20.

(38) Yet another advantage of the present invention lies in the fact that the container 1 is so designed as to improve the quality of differentiated waste collection, since the features of the mask 50 allow every user to carry out a high-level separation of the different types of waste to be delivered.

(39) The container for waste collection described herein by way of example may be subject to many possible variations without departing from the novelty spirit of the inventive idea; it is also clear that in the practical implementation of the invention the illustrated details may have different shapes or be replaced with other technically equivalent elements.

(40) It can therefore be easily understood that the present invention is not limited to the above-described container for waste collection, but may be subject to many modifications, improvements or replacements of equivalent parts and elements without departing from the inventive idea, as clearly specified in the following claims.
