For environmental reasons - and for reasons of resource conservation in general - glass containers such as bottles and jars are increasingly being recycled.

For this purpose, glass containers are positioned in easily accessible places, i.e. in open spaces, near schools, department stores, etc. They are provided by licensed companies and emptied on a regular basis.

The glass containers are made of sheet steel or plastic. Their shape and size are such that the empty glass can be easily thrown in and that emptying at the site of subsequent processing can be carried out quickly. The containers have a volume of 1-5 m ³ . After being picked up using a vehicle crane, they are easy to transport.

This method of disposing of glass containers has proven itself and has become widespread. - However, there is still a major shortcoming: when the empty containers are thrown in, they create very disturbing noises due to the reverberant surfaces of the containers.

It is not uncommon for containers to be filled at night, on Sundays and public holidays, which then leads to complaints from the neighbours living close to the storage locations.

-This innovation provides a solution. It is a soundproof glass container, the use of which significantly reduces any noise that may be generated. The following descriptions and images serve as an explanation.

example 1

(^ The glass container (Figure 1) is internal, i.e. bottom (a), side walls (b), and

Cover walls (c) completely covered with a PVC-coated polyester fiber felt. The PVC layer (d) weighs 1500 g/m ² , the felt (e) weighs 1550 g/m ² , the total thickness is 10 mm (Figure 2).

Example 2

The floor (a) and the side walls (b) of the glass container (Figure 1) are completely covered with a mechanically and adhesively bonded fiber fleece in accordance with DIN 61210 (Figure 3). The top walls (c) are equipped with an absorption material. The fiber fleece is based on polypropylene fibers (f) and SBR binder (g) and has a weight of 1000 g/m ² and a thickness of 10 mm. The absorption material is made of shredded cotton (h) and phenolic resin (i), 1000 g/m ² ,10 mm. (Figure 4).

Example 3 ; ;;,;,,<;\,; , ·',,;< _f ^r

The floor (a) of the glass container (Figure t) is covered with a PVC-coated polyester fiber fleece, according to Example I _, the side walls (b) with a fiber fleece according to Example 2, the top walls (c) also correspond in terms of equipment with the absorption material of Example 2.

Sound measurements demonstrate the excellent effectiveness of the described equipment variants:

For the equipment variants described, the level reductions ranged from 10-20 dB (A) -

Of course, the new glass container is not limited to the equipment variants described; the use of other materials that meet the mechanical and acoustic requirements is also conceivable and possible.
