Abstract
The invention relates to a closure system for two container parts to be connected to one another, for example for a lighting unit, which system can be mounted rapidly, is corrosion resistant, provides a tightness which can be monitored, and can be removed rapidly at any time and mounted again. According to the invention, the opening line (1) between the container parts is surrounded by a shrink sleeve (2) and may additionally be provided with a layer of sealing compound (4), preferably a hotmelt adhesive.
Claims13
A casing for an air field light comprising a rigid container consisting substantially of first and second parts, each said part having a flange portion, said flange portions being connected to one another so as to seal the container;
- and
- a shrink sleeve surrounding said flange portions and providing a water-tight seal of said first and second parts.
A method for closing a casing for an air field light comprising a rigid container consisting substantially of first and second parts, each said part having a flange portion, said flange portions being connected to one another so as to seal the container, and a shrink sleeve surrounding said flange portions and providing a water-tight seal of said first and second parts, wherein a gas pressure within said container is reduced relative to an external atmospheric pressure, comprising:
- placing said container parts together along the flanges, while leaving open an orifice being defined in one of said container parts for receiving a cable duct;
- heating the container to at least 50.degree. C.;
- surrounding the container in the region of an opening line defined between said flanges with a heat-shrinkable shrink sleeve;
- heating at least said heat shrinkable sleeve to its shrinking temperature;
- and
- closing said orifice.
