Definitions
- the present invention relates to gas cylinders and, more specifically, to liquefied petroleum gas cylinders, according to the preamble of claim 1.
- a bottle of liquefied petroleum gas has a body in one pressure-resistant material, in particular metal or material composite.
- a valve which, when it is closed, prevents gas from leaving the body.
- the action on the tap of the regulator causes a piston to move, allowing gas to flow out of the body.
- the invention provides a remedy with a bottle according to claim 1.
- Other improvements are defined in claims 2 to 6.
- the capsule in particular in plastic material, is not suitable for withstand the very high pressures prevailing, for example in a bottle liquefied petroleum gas, but may contain a gas leak occurring on the valve, as long as the leakage gas pressure does not exceed not a certain value, notably 14 bar, lower than the gas pressure prevailing in the body and however it can be easily removed from the valve by the user by moving the part which does not delimit the chamber.
- the valve includes a tubular metal chimney and the capsule includes an upper wall from which comes a tubular part open towards the bottom, the external lateral face of the tubular part coming into contact with interposition of a seal with the inner side face of the fireplace.
- the pressure it applies to the tubular part allows, by through the seal, to ensure a good seal between the inner side face of the chimney and the outer side face of the tubular part, so that gas cannot escape from the chamber.
- the chimney has an outer wall provided a shoulder and the capsule includes a skirt, a projection on the face inside of the skirt snapping under the shoulder.
- the projection may for example be a rib.
- This rib which can also be replaced by protrusions, preferably distributed evenly around the inside of the skirt, comes behind an outer rim of the valve and thus ensures that even if gas leaks and tends to repel the capsule, it is retained. Leaking gas comes to the inside of the tubular part, since the latter is open downwards and pushes the lateral surface of the tubular part towards the adjacent wall of the valve, which ensures tightness.
- the skirt flares down, which allows more easily snap on the protrusion.
- the skirt is extended downward, on the one hand, over part of the lower edge of the skirt by a tongue which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, larger than the first part, by a band connected to the lower edge of the skirt by a first line of lesser resistance to tearing.
- This band serves as a tamper-evident band. Onne can disengage the capsule only after having torn off this strip.
- the tongue connects the skirt to a ring. Even when the strip is removed, the cap remains held on the valve in a position where it tends to come back automatically due to the elasticity of the tongue, the entire capsule is preferably made of flexible plastic. The capsule still protects the valve from dust, snow, water, heat, sun, sand and other deposits of solid matter, but also valve leaks even after the tamper-evident strip has been removed.
- the lower edge of the band is connected to the ring by a second line of least resistance to tearing. This second line of least tear resistance constitutes an additional fixation of the strip and prevents it from coming off when inadvertently or by accident, the first line of least resistance to tearing is torn.
- the plastic capsule is formed of a cap, which comprises an extended circular upper wall 1 down by a skirt 2 which flares down.
- a rib 4 going all around the skirt 2 is provided on the inner face thereof.
- the skirt 2 is extended downward, on the one hand, over part of the edge lower of the skirt by a tongue 5 which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, which is larger than the first part, by a band 6 connected to the lower edge of the skirt 2 by a first line 7 of lower tear resistance, formed under the form of a series of equidistant studs.
- the tongue 5 connects the skirt 2 to a ring 8 of larger diameter than that of the lower edge of the skirt.
- the lower edge of the strip 6 is connected to the ring 8 by a second line 9 of least resistance to tearing.
- Figure 3 is a sectional view from the top of a next bottle the invention.
- This bottle has a body 10 surmounted by a neck 11 in which is screwed a valve, generally designated by 12.
- This valve includes a valve body forming an upper tubular chimney 13 the outer face of which has a shoulder 14 intended to cooperate with the projection 4.
- a ring 15 In the inner face of the body 10 is held by a ring 15 to stop a ball 16 forming a flow limiter.
- the ring carries a press spring 17 inside which is threaded a crew 18 with piston 19 pushed back upwards by a spring 20, one end of which rests on the face top of the spring press 17 and the other end of which rests on a rim 21 of the crew.
- a seal seal 22 which comes into contact with a seat 23 from the body 13 of valve.
- a seal 24 the inside diameter of which substantially corresponds to the outside diameter of the tubular part 3, in so that when it is threaded into the chimney 13, it applies there tightly through this seal 24 and defines a chamber C waterproof. If the valve leaks, gas comes into chamber C, but there is kept locked up without being able to get out of it and without any more than the force due at the pressure applied to the capsule is sufficient to lift it from the valve 12 and to set it aside due to the cooperation of the projection 4 and the shoulder 14.
- the capsule snaps on the rib 4 on the shoulder 14 of the valve 12 of the gas cylinder. In this position, it seals, even if valve 12 is leaking.
- the user detaches the tamper-evident band 6, then disengages the rib 2.
- the opening of the valve 12 can then be released, by tilting the cover relative to the tongue 5 serving as a hinge.
