[0001] The present invention regards a waste container of the type comprising a containment
body and a lid hinged thereto.
[0002] Various types of waste containers of different dimensions which are particularly
used for the sorted collection of dry and wet waste, are known.
[0003] Regarding the aforementioned containers, the problem related to acoustic pollution
that occurs upon closing the lid on the containment body of the container is well
known.
[0004] The certification of a product according to the UNI EN 840-1 standard includes -
among others - an acoustic test (according to the 2000/14/CE directive).
[0005] One of the situations in which the noise emitted by the product - measured in decibels
- is carried out is the lid closing step during the final impact of the lid on the
containment body.
[0006] The emission of a targeted report on the acoustic tests or the awarding of the UNI
EN 840-1 certificate by any certifying body entails the obligation by the manufacturer
to indicate the value of the noise emitted by the product by engraving the special
symbol referring to the data in decibels, with the aim of revealing the level of emitted
acoustic pollution to the owner or users.
[0007] Regarding this, the patent document
EP 1 584 576 A1 describes a device that absorbs the noise in the waste container lids.
[0008] Such device is arranged on the lid of the aforementioned containers and consists
in a strip of material moulded together with the lid. The strip is obtained arc-shaped
and it has the convexity thereof oriented towards the body of the container.
[0009] The drawback of this solution lies in that the complete moulding of the lid is complex
to perform and - furthermore - when the lid of the container is closed, the arc-shaped
strip tends to bend on the perimeter edge of the containment body upon the impact
of the lid on the latter.
[0010] Another solution to the noise problem is described in patent document
EP 0 774 424 A1. Such patent application describes a waste container comprising a containment body
and a lid hinged to the latter.
[0011] Patent document
DE 20204062 U1 describes a waste container in which the edge of the container which receives the
lid has a rubber damper provided with a threading.
[0012] The hinges exert a mechanical friction action when the lid is closed on the containment
body.
[0013] Furthermore, the upper perimeter edge of the containment body is provided with a
plurality of rubber elements, spaced from each other and projecting from the aforementioned
perimeter edge. Such rubber elements serve as elements for damping the impact of the
lid on the containment body.
[0014] However, this solution reveals the drawback according to which the aforementioned
damping elements, given that they project from the upper perimeter edge of the containment
body, do not collapse completely upon closing the lid and thus do not perform their
function of damping the impact of the lid fully.
[0015] The present invention has the object of overcoming these drawbacks.
[0016] In particular, an object of the present invention is to provide a waste container
that is capable of lowering the intensity of the noise caused by the closure of the
lid to actively contribute towards reducing acoustic pollution.
[0017] A further object of the present invention is to provide a waste container that is
provided with one or more elements for damping noise when closing the lid, which allow
closing the lid with or without locking devices in any case.
[0018] The aforementioned objects are attained by the present invention regarding a waste
container according to the main claim.
[0019] Further detailed characteristics of the present invention are outlined in the dependent
claims.
[0020] Advantageously, the waste container according to the invention provides for that
in the perimeter edge surrounding the loading mouth of the containment body there
is obtained, integrally or by adding elements, at least one window traversed by a
bridge element that is elastically deformable and preferably made of the same material
as the containment body or by different materials co-injected into the product. Such
bridge element elastically absorbs the impact of the lid during the closing step on
the containment body.
[0021] According to a preferred embodiment, in the perimeter edge there are obtained two
mutually symmetrical windows, each of which is traversed by a bridge element.
[0022] Still advantageously, the bridge element belonging to the waste container according
to the invention, is compressed, it deforms and tends to collapse completely into
the window it belongs to upon impact, so that the lid reaches the ideal closing height
generating the least noise possible.
[0023] The aforementioned objects and advantages shall be more apparent from the description
of a preferred embodiment of the invention, outlined hereinafter by way of non-limiting
example, with reference to the attached drawings, wherein:
- fig. 1 represents an axonometric view of a waste container according to the invention;
- fig. 1a represents an enlarged view of a detail of fig. 1;
- fig. 2 represents an axonometric view of a detail of fig. 1 with the lid lifted;
- fig. 3 represents an axonometric view of the detail of fig. 2 with the lid closed;
- fig. 4 represents a lateral view of a detail of the container of fig. 1 in closing
step;
- fig. 5 represents a lateral view of the detail of fig. 4 with the lid closed.
[0024] With reference to fig. 1, it shows a waste container, indicated in its entirety with
1, comprising a containment body
2 and a lid
3 hinged thereto.
[0025] In the containment body
2 there is obtained a containment compartment
4 for collecting waste.
[0026] The containment body
2 of the container
1 is delimited - at one end - by a surface
5 for resting against the ground. At the base of the container
1 there is a pedal
6 for the mechanical lifting of the lid
3.
[0027] Still with reference to fig. 1, at the opposite end of the resting surface
5 there is observed the presence of a loading mouth
7 which serves for loading waste into the container
1.
[0028] The containment body
2 of the container
1 is delimited, in proximity of the loading mouth
7, by a perimeter edge
8 which surrounds the loading mouth
7 entirely.
[0029] According to the present invention and with reference to figs. 1-3, in the perimeter
edge
8 there are obtained two windows
9 spaced from each other and symmetrical with respect to an axis
X of the perimeter edge
8.
[0030] Still according to the present invention and with reference to the detail of fig.
1a, each window
9 is substantially quadrangular-shaped and it is traversed by a bridge element
10 made of elastically deformable material and connected to two ends
11 of the edge
90 of the window
9, while the other two mutually opposite ends of the bridge element
10 are detached from the window
9.
[0031] With reference to figs. 3-4, each bridge element
10 is suitable to take a first configuration, in which it projects from a plane
P which contains the exposed surface
13 of the perimeter edge
8, and a second configuration in which the bridge element
10 is comprised in the perimeter edge
8.
[0032] According to a preferred and non-exclusive embodiment, such bridge element
10 is made, through localised variation of the thickness in some areas, using the same
material with which the containment body
2 is made.
[0033] As observable in figs. 1a-5, the bridge element
10 consists of a plurality of reliefs
100, lowered and of the same height, except for the central relief
100a which has a height slightly greater than the other reliefs; such reliefs are wave-shaped
starting from each of the ends
11. Basically, the profile of the bridge element
10 is symmetrical with respect to an axis
Y orthogonal to the plane identified by the window
9 (see fig. 1a).
[0034] The plane
P to which the perimeter edge
8 of the containment body
2 belongs is also the plane to which each window
9 belongs.
[0035] In the embodiment described herein there are present two windows; however, in a variant
embodiment not shown in the figures, the number of windows can also be different,
for example a single window at the front part of the perimeter edge or even three
or more windows spaced from each other.
[0036] In fig. 1a it should be observed that, between any two of the reliefs adjacent to
each other, there is present a groove
101; thus, the profile of the bridge element
10 provides for the presence of a plurality of reliefs
100 and a plurality of grooves
101 such that each relief
100 is preceded and followed by a groove
101 and vice versa.
[0037] The result of such conformation is that the bridge element
10 of the window
9 has a substantially sinusoidal-shaped profile with a relief
100a, having a greater height than that of the other reliefs
100, which is in a central position and which is symmetrical with respect to the aforementioned
axis
Y.
[0038] However, according to alternative embodiments not represented herein, the reliefs
could also have an increasing height starting from the ends towards the centre.
[0039] Advantageously, as observable in figs. 2-5, the substantially sinusoidal-shaped profile
of the bridge element
10 facilitates the collapsing thereof into the window
9 which receives it when the edge
12 (visible in fig. 1) of the lid
3 is at contact with the perimeter edge
8. Same case obviously applies also to the other window
9.
[0040] Being elastically deformable, the bridge element
10, as observable in fig. 5, when the lid
3 comes into contact with the perimeter edge
8 of the containment body
2, it takes a second configuration in which it is collapsed into the perimeter edge
8. All this will be illustrated further in detail hereinafter.
[0041] Operatively and with reference to all the figures, the waste container according
to the invention operates as follows.
[0042] When the user lifts the lid
3, manually or by means of a pedal
6, in order to fill the containment compartment
2 with waste, the bridge element
10 is in the first configuration, visible in figs. 2-3, where the bridge element
10 is projecting with respect to the exposed surface
13 which is contained in the plane
P. Basically, the bridge element
10 is in a first inoperative configuration.
[0043] Once through with filling the container
1 with waste, manually or using the pedal
6 the user lowers the lid
3, or lets it drop by gravity, until the edge
12 thereof comes to contact with the bridge element
10.
[0044] At this point, the bridge element
10 starts bending towards the central part at the level of the relief
100a having the greater height and deforming collapsing inwards so that the mass thereof
progressively recedes into the overall dimension of the window
9. It should be observed that only the relief
100a, having a greater height as compared to the other reliefs
100, deforms while the other reliefs
100 do not deform.
[0045] At the end, as observable in fig. 5, the edge
12 of the lid
3, with respect to the first inoperative configuration, is in a second operative configuration
in which it is in a very closed position with respect to the perimeter edge
8 without entirely reaching the plane
P and the bridge element
10 is collapsed into the window
9 except for the relief
100a which projects from the perimeter edge
8.
[0046] The relief
100a of the bridge element
10 basically supports the edge
12 of the lid
3 preventing it from abutting against the perimeter edge
8 and thus keeping it slightly lifted by the latter.
[0047] At the end, in the aforementioned second operative configuration, the bridge element
10 is collapsed into the respective window
9 except for the central part thereof, represented by the relief
100a arranged centrally in the bridge element
10 and which, actually due to the fact that it has a greater height than the other reliefs
thereof, serves as an element for supporting the lid
3.
[0048] The bridge element
10 advantageously serves as a damping element in that it absorbs the kinetic energy
with which the lid
3 drops on the perimeter edge
8 and thus reduces the impact energy with which the lid
3 impacts against the containment body
2.
[0049] Basically, the bridge element
10 serves as a damping element which, by absorbing the kinetic energy of the lid
3, also reduces the sound impact and thus the intensity of the noise which would be
generated by the impact of the lid
3 against the perimeter edge
8.
[0050] As a matter of fact, the contact between the lid
3 and the perimeter edge
8 of the containment body
2 only occurs on the relief
100a, when the kinetic energy of the lid
3 is almost null by then.
[0051] Still advantageously, each bridge element
10 forms a single body with the perimeter edge
8 of the container
1, and it is thus obtained by means of a single moulding alongside the entire container
1. According to other embodiments not illustrated herein, the windows
9 can be one or more than one, and they can be connected even to the perimeter edge
8 only at some points, so as to manage the bending of the bridge element
10 in a controlled manner.
[0052] According to further embodiments not illustrated in the figures, it is also possible
that the windows
9 can be arranged close to each other and that there be an interruption line between
them. For example, there can be a variant embodiment in which there are four windows
arranged close to each other two by two and in which there are two interruption lines,
each of which extends between two adjacent windows.
[0053] Still advantageously, it was observed that, using the container according to the
invention, the impact reduces at lower noise levels with respect to the models of
waste containers already available in the market and without the anti-noise system.
[0054] In the light of the above, it is clear that the waste container according to the
invention attains the pre-set objects.
[0055] Preferably but not necessarily, the waste container according to the invention is
used for 120-litre containers, but it also applies to containers of different sizes.
[0056] Furthermore, the waste container according to the invention is particularly indicated
for use in outdoor public spaces, like the streets.
[0057] In the execution step, the waste container according to the invention can be subjected
to modifications which, though not described herein, shall be all deemed protected
