Abstract

Sealing collar for gasoline lighters, characterized in that the sleeve made of elastic and gas-tight or largely gas-tight material, eg. As rubber exists.

Description

Gasoline lighters of conventional design have a wick, which is impregnated with gasoline and ignited by another device. This entails that the soaked wick must be protected by a suitable cover, the cover having to take over several functions in the closed state: it must suppress the air supply of the burning flame and thus extinguish it, they must also the gasoline-soaked Wick when transporting in bags or the like protect against contact with other objects and prevent evaporation or leakage of gasoline. The latter is not sufficiently achieved in conventional gasoline lighters, since the covers are not completely gas-tight and thus can not completely prevent evaporation or leakage. Therefore, in conventional gasoline lighters, the entire supply of gasoline is lost within a relatively short time. As a result, the lighter must be refilled frequently and may not be ready for use when needed.

There are already several constructive solutions to this problem. In the document with the number DE000000336524A and the title "pyrophoric lighter", the problem is solved in that the reservoir is closed by a spring-loaded valve. When the reservoir is squeezed, the valve opens and gives off only a small amount of gas. The rest of the stock remains protected in the storage tank from evaporation or leakage. In the document with the number DE000000331526A_1 and the title "Reibfunkenfeuerzeug" the solution is also prepared by the fact that the reservoir itself has a shutter mechanism.

However, these solutions have not prevailed because they are structurally very complex. Most gasoline lighters currently on the market have a simple and therefore robust and cost-effective design. You have a reservoir that does not adequately protect against the evaporation of its contents and a housing cap to reduce evaporation while protecting the wick and ignition mechanism and extinguishing the flame.

The invention presented here represents a cuff which solves the problem of evaporation of gasoline in gasoline lighters of this common type. The cuff is pulled over the lighter so that it spans the gap between the lid and the body. Since the cuff is made of elastic material, it fits closely to the body and lid of the lighter. The cuff seals the gap between the lid and body gas-tight or almost gas-tight, so that no gasoline or petrol vapor from the interior of the lighter can escape. An evaporation of the gas from the wick of the lighter is thereby prevented or slowed down, that the space around the wick is separated by the cuff almost or completely gas-tight from the ambient air. As a result, the partial pressure of the gasoline vapors in the space around the wick increases so much that hardly any evaporation takes place.

To open the lighter, the cuff is turned over so that the gap between the lid and body is free. The rewinding can be done downwards so that the cuff remains on the body, or upwards so that the cuff remains on the lid. The invention is suitable both for lighters in which the lid is fastened with a hinge on the lighter, as well as for those in which the lid is completely removed for opening when using the lighter.

An embodiment of the invention will be described with reference to 1 to 3 explained. Show it:

1 the closed lighter,

2 the lighter in the open state, with the cuff turned upside down to allow the lighter to open.

3 the lighter in the open state, with the rolled-up cuff remains on the lid.

In the figures, the lid ( 1 ) and the body ( 3 ) of the lighter and the sealing cuff ( 2 ). In the open state are in 2 and 3 the wick ( 4 ) and the friction wheel ( 5 ) of the lighter.
