Description

Double walled liquid container

The innovation concerns a double ^- walled liquid container, especially an Eeizcltank, with an inner shell made of fiberglass-reinforced synthetic resin, which with an outer shell forms an intermediate space that accommodates a foam layer.

Double-walled container, especially for receiving. grunavasser-. Contaminants liquids, such as heating oil, are used, 'offer a relatively high security against leakage and enable determine the timely by arranging a probe before. leakage liquid, v / which through the inserts into the Leaked space.

It was common practice to separate double-walled containers by assembling g * "To produce inner and outer skis. This creates difficulties, however, especially with regard to the seal and the spacing between the two shells.

A double-sided container is already known, the In.iensc: ...- Ie made of glass fiber reinforced. Made of plastic. The inner shell will by spraying the plastic onto the inner wall of a finished Outside container manufactured. By shrinking the plastic a gap is created in which a filling compound, e.g. plastic foam, is introduced. The manufacture of this container continues. however, the presence of an already finished outer shell precedes it.

The present invention aims at a double-walled container which offers greater security . Leak fluid, and what the previously existing disadvantages related !. the sealing and the spacing between the two shells avoids.

For this purpose there is the one with the inner shell and the one in between Foam layer in one;:; Operation of pressed external screws of the container made of glass fiber reinforced synthetic resin. Since both the

The inner and outer shell are made of fiberglass-reinforced synthetic resin exist, the possibility is offered to produce each of the two vial cups in one operation, so that the two The seam connecting the shells is absolutely tight and the distance remaining between the two shells can be precisely maintained.

The foam layer located in the gap is made according to an essential further development of the furnace from open-pored, porous space. In contrast to the previously known fillers, such as closed-cell foam, this achieves that any leakage fluid that may seep through can certainly spread through the foam layer.

Its probe, which responds to leakage fluid, is arranged in such a way that that it protrudes into the foam layer. Leakage fluid, Polythene spreads through the foam layer, becomes üit Safety reported by the probe.

In the drawing, an embodiment of the iieuerung is shown, show it:

The outer shell β and the inner shell 7 are grounded on the same side as that between these two shells Foam layer in one operation according to the already known Sandwich method made. The lower double-sided half-shell 3 is manufactured in a corresponding manner.

Ita present embodiment is a probe 10 respectively. 10 ', which responds to leakage fluid, arranged in the "wall of the upper half-shell 2 and the lower half-shell 3 in such a way that that it protrudes into the foam layer 9. Ba possibly occurring Leak fluid can flow through the open-pored Foam layer of the two halves 2 and 3 can spread out, leakage phenomena are foreseen with certainty. Furthermore is the upper half-shell 2 is provided with a filler neck 11. The present statement avoids the possibility of a possible leak at the junction of the outer shell 6 with the inner shell 7 reduced and relocated to the connecting f! See 4 and 5, where they are easily controllable.

In the present case, the two half-shells are in front. the openings for the probes 10 and 10 ', as well as for the filler neck 11! seen, formed identically, which simplifies their manufacture will. However, it is within the range of the present firing, to move the connecting flanges 4 and 5 to a higher point such that the upper half-shell 2 has only a small height and as a cover for the actual container in this case forming lower half-shell 3 is formed.
