Container lid with a sound dampener

Description

OBJECT OF THE INVENTION

[0001] The present invention relates to a container lid which comprises a sound dampener according to the preamble of claim 1, especially for containers used in the field of the urban waste collection, provided with a container body to which the container lid is suitably hinged.

[0002] The object of the invention is to achieve that, when the lid closes abruptly, the noise pollution effect caused by the impact between both elements is substantially dampened or minimised.

BACKGROUND OF THE INVENTION

[0003] In the aforementioned type of containers, both when the waste is deposited therein, and when they are subsequently emptied into the refuse collection vehicles, the lid normally abruptly hits against the opening of the body, being a very noisy manoeuvre, with considerable noise pollution, whose effects are increased when the manoeuvre is performed in the silence of the night.

[0004] To try to get round this problem, providing the lids of this type of containers with a dampening device is known, in some cases metal springs and in others rubber blocks, solutions which are largely unsatisfactory, due to the greater or lesser structural complexity of the dampening device, with the consequent negative impact on costs, or the little durability of said elements. Document DE-A-43 15 554 discloses a container lid according to the preamble of claim 1 for a container of waste products or materials, provided on its lower edge with a rim, inside which are established reinforcements or thickenings which also determine a lower base or flat surface towards which blind and vertical holes open designed to receive respective dampening pivots, which may be of rubber, plastic or soft polyethylene, and which, in any case, have a rod whereby they are inserted and fixed in the corresponding blind orifice of the lid. This solution is relatively complex, not only because said pivots constitute physically independent parts of the lid, and of a material different thereto, which should be produced in independent manufacturing processes, but the subsequent mounting of said pivots on the lid is also required, to which it is necessary to further add the risk of loss thereof throughout the time of use of the container.

DESCRIPTION OF THE INVENTION

[0005] The container lid proposed by the invention resolves in a fully satisfactorily manner the aforementioned problem, being a solution of maximum structural simplicity and minimum cost, which offers optimal functional features, which are maintained with time. According to the invention, the sound dampener of the container lid consists of a type of strip by way of an arc, forming a single piece with the container lid protruding with respect to the lower support edge of the container lid, said strip comprising a window or groove allowing the elastic deformation of the strip upon impact. The sound dampener may be repeated and distributed on suitably distributed points to boost the dampening effect and is included in the plane corresponding to the lower support edge of the lid, or positioned immediately outside or inside said plane.

[0006] In any case, during the lid-closing maneuver, it hits against the opening of the container body via the midpoint of each one of said arcs or strips, causing an elastic deformation therein which dampens the impact and which, consequently, also dampens the noise pollution.

DESCRIPTION OF THE DRAWINGS

[0007] To complement the description being provided and with the aim of helping towards a better understanding of the characteristics of the invention, in accordance with a preferred example of practical embodiments thereof, a set of drawings is attached, being an integral part of said description, wherein the following is represented with an illustrative, non-limiting character.

Figure 1. It shows, according to a perspective view, a container lid, provided with a sound dampener in accordance with a first variant of the embodiment thereof, wherein the lid incorporates a pair of dampeners, and they are positioned outside the imaginary plane corresponding to the support edge thereof.

Figure 2. It shows an enlargement, also in perspective, of the above figure, at the level of said dampener.

Figure 3. It shows a perspective close-up of a container lid in accordance with a second variant thereof, wherein the dampeners are positioned on the plane corresponding to the edge of the lid.

Figure 4. It shows, finally, another perspective close-up of a container lid, in this case on its inner side and corresponding to the third variant of the embodiment, i.e. to that wherein the dampener is positioned inside the plane corresponding to the edge of the lid.

PREFERRED EMBODIMENT OF THE INVENTION

[0008] In view of said figures, it can be observed how the sound dampener can be repeated as many times as desired throughout the contour of the lid (1), but logically opposite its hinging means (2) to the body, not represented in the drawings, is materialized in a strip (3), produced as a single piece with the lid (1), i.e. from the material of the latter and integrated therein.

[0009] Said strip (3) consists of a type of arc of reduced section, with convexity oriented towards the container body, for which purpose, a window (4) is formed immediately thereabove, which permits elastic deformation, said strip (3) being connected to a bent external side projection (5) of the lid (1), as in the example of embodiment shown in figures 1 and 2, and can be integrated in the lid edge (6) plane, as in the case of figure 3, wherein the window (4) is boosted by a small curve concave notch (7) of the edge (6), or can be positioned within said edge (6) of the lid, as in the case of figure 4, wherein it is established on an internal reinforcement or thickness (8), rigidized by means of a rib (9), in this case the window (4) consisting of a groove parallel to the strip or arc (3).

[0010] Evidently, the solutions shown in the figures are only some of the possibilities existing to that effect, obvious for someone skilled in the art, all of them having the common denominator of the existence of said strip (3) in the form of an arc, forming a single piece with the lid (1) and able to deform elastically, absorbing the impact, when this occurs.

Claims
