Definitions
- a high pressure gas cartridge may move or fly in reaction to escape of gas from within when the cartridge is in distribution or in use, and this is very dangerous.
- causes of moving or flying of such a cartridge include the following. A first is the case when the cartridge has been thrown into a fire and the sealing plate has exploded due to excessive inner pressure.
- a second is when the sealing plate has been pierced by a boy's mischief with a nail.
- a third is when a cartridge is removed from a piercing device with seme gas remaining in it.
- the present invention relates to high pressure gas cartridges which are safe in such conditions.
- JP-B-57(1982)-54679 discloses a high pressure gas cartridge with a safety device.
- the device is provided with a small chamber having an orifice under the sealing plate, and is so planned as not to produce a rocketing or jetting gas stream, as the gas is throttled by the orifice when its temperature becomes high and the sealing plate is broken.
- the orifice has an object to allow the gas to flow gradually when its pressure becomes high at high temperature.
- the device is impractical as the cross-sectional area of the orifice is very small and the gas flow induced by the inner pressure at the normal temperature is very small.
- Both the sealing plate and the small chamber with the orifice must be pierced, if this type of device is to be used effectively at normal temperatures, and that needs strong force and a piercing pin with a long stroke. This is also impractical.
- JP-B-58(1983)-27439 discloses a gas cartridge having an orifice in an opening. Interest is directed only to controlling quantity of flow of gas. insufficient consideration has been given to the task of charging the cartridge with gas, and that takes a long time. Accordingly, the rate of production of such cartridges is limited, so that the cost of production has to be high.
- JP-A-5586995 discloses a gas cartridge in which an orifice in a regulating chamber is used to reduce the pressure of gas to prevent the cartridge moving by reaction when the pressure in the cartridge rises due to an increase in temperature or when the sealing plate of the cartridge is broken.
- the cross-sectional area of the orifice must therefore be very small so that gas flow therethrough is limited during normal use.
- An object of the present invention is to provide high pressure gas cartridges with a double safety device, which can be charged speedily with gas, which can be saved from rupture of the cartridge body when the inner pressure is increased excessively, which do not move or fly in reaction even if the sealing plate has been pierced manually and the inner gas can flow out freely into atmosphere, and which in general use can allow gas to be discharged at a useful flow rate, by piercing the sealing plate.
- Another object of the present invention is to minimize the force to be exerted on, and the stroke of a piercing pin for piercing the sealing plate.
- a further object of the present invention is to allot the safety function to the safety device of the sealing plate when the inner pressure has increased excessively and to a gas regulator when the inner gas flows freely after the sealing plate has been broken.

- sealing plates 2 are all put on the end face 13 of the opening 11 of the body 1. Gas is charged into the body 1 through a clearance formed between the body 1 and the sealing plate. The clearance is formed either by means of radial protrusions 23 of the sealing plate 2 or of radial grooves 14 in the end face 13 of the body 1. After the body 1 has been charged with gas, the sealing plate 2 is joined onto the body 1, as before, such as by welding or by calking.

- Fig. 12 is a plan with that part of the sealing plate below the centre line removed, and
- Fig. 13 is a sectioned side view similar to Fig. 1 of a further embodiment in which the regulator is composed of a portion with an orifice and a filter portion.
- 1 is a body of capacity less than 100 cc and into the body 1 a high pressure gas, such as C02 or O2, is charged. There are two types of the body 1, one of which has a
shoulder 12 on the inner wall around an opening 11 (see Figs. 1, 3, 5 and 9) and the other has no such shoulder (see Figs. 6, 7, 8, 11 and 13). - 2 is a sealing plate, which is a usual safety type having a
recess 21 operable to vent the inner pressure through a hair crack when the inner pressure rises excessively. There are two types ofsealing plate 2, one of which has acircular leg 22 on its underside (see Figs. 1, 3, 5, 6, 8, 9, 11 and 13) and the other has no such circular leg (see Fig. 7). - These
sealing plates 2 are all put on theend face 13 of the opening 11 of the body 1. Gas is charged into the body 1 through a clearance formed between the body 1 and the sealing plate. The clearance is formed either by means ofradial protrusions 23 of thesealing plate 2 or ofradial grooves 14 in theend face 13 of the body 1. After the body 1 has been charged with gas, the sealingplate 2 is joined onto the body 1, as before, such as by welding or by calking. - 3 is a regulator for regulating gas flow through it. The body 1 is provided with the
regulator 3 at the inner side of thesealing plate 2 and in a gas flow path. Theregulator 3 has anorifice 31 which is operable to throttle gas flow at the normal temperature within the body 1 so as not to move or cause the cartridge to fly due to reaction to gas emission, and also forms aclearance 32 for flow of charging gas around itself within the body 1. Theregulator 3 may be a plate, but, in the examples shown in the drawings, theregulator 3 takes the form of a cylinder having abottom wall 33 and aside wall 34. - The
clearance 32 may take various forms. One form ofclearance 32 is between the periphery of theregulator 3 and the inner wall of the body1 (see Figs. 6 to 8, 11 to 13). Another is betweenradial ribs 35 and the inner wall of the body 1 (see Figs. 1 to 5, 9, 10). Theclearance 32 may be formed by radial grooves. At all events it is desirable for theclearance 32 to be formed when theregulator 3 is placed in the body 1. - There are various possible dispositions of the regulator, such as to put the regulator on the
shoulder 12 of the body 1 (see Figs. 1, 3, 5, 9), to carry it by calking the lower end of thecircular leg 22 of the sealing plate 2 (see Fig. 6), to unite theregulator 3 and thesealing plate 2 as one body by a solderedportion 41 by which theregulator 3 is soldered directly to the sealing plate (Fig. 7), to spigot the upper portion of the regulator into the aperture formed by thecircular leg 22 of the sealing plate 2 (see Figs. 8 and 13), to fix the regulator to the sealing plate in a body (Fig. 11), etc. - Fig. 8 shows a
filter 51 supported against the underside of theorifice 31 so that theorifice 31 may not be clogged with residual swarf in the body. Thefilter 51 does not have a regulating function corresponding to that described for theorifice 31. Though such a filter is not shown in Figs. 1 to 7, the same effect can be obtained by providing such a filter at the underside of the orifice in each of those embodiments. - A filter, which is essentially different from the
filter 51 of the embodiment of Fig. 8, is used as a gas flow regulator in the embodiments of Figs. 9 to 13. The filter is of the continuous foam type, and the interstices are selected for a certain pressure of gas. The filter regulates gas flow, either alone or in combination with theorifice 31, such that the regulated gas flow is sufficient to actuate a device which uses the gas (for example an oxygen inhaler) but is not enough to move the cartridge by reaction even if the cartridge is in a state where the sealing plate has been broken and the gas can flow out freely. - Fig. 13 shows a
regulator 3 which consists of acylinder portion 3b with theorifice 31 and a filter portion 3a. Of course the regulated gas flow through both portions is determined as stated above. In this case the filter portion 3a can be thinner than in the embodiments of Figs. 9 and 11. When the body has been charged with gas and thesealing plate 2 has been joined to the body 1, it is necessary in several embodiments to bar direct access from the interior of the body 1 to thelimited recess 21 of the sealing plate through theclearance 32, in order to ensure that theregulator 3 functions as it should. - Therefore, in the embodiment of Fig. 1, the top of the
regulator 3 is pressed onto the underside of thesealing plate 2. In the embodiment of Fig. 3, the upper inner portion of the regulator is closely fitted onto the outer periphery of theciruclar leg 22, and in the embodiments of Figs. 5 and 9, the lower portion of thecircular leg 22 is pressed into theregulator 3. - When using the cartridges shown in the drawings, after the cartridge has been attached to a piercing device, it will be sufficient to pierce the sealing
plate 2 only. Also, by employing a material for the regulator which a needle N can pierce readily, as in the embodiment of Fig. 11, the force that has to be applied to the needle and the stroke of the needle can be minimized. A required quantity of gas is taken out from within the body, through the regulator, by piercing. - When the cartridge is overheated, say by throwing into fire in error or by a fire, the gas within the body 1 expands and the pressure increases. At a certain pressure, the sealing
plate 2 begins to bend outwardly and a hair crack through the bottom of thelimited recess 12 forms. The gas in the boy begins to flow out gradually through the crack and an explosion of the body 1 is avoided. Also when, at the normal temperature, the sealingplate 2 is pierced by mischief or the cartridge is removed from the piercing device with some gas remaining in it the rate of escape of gas is kept fixed by theregulator 3 so that the cartridge does not fly and damage is not caused to men and beasts or structures. - The diameter of the
orifice 31 required to avoid the cartridge taking off is, in the case of C02 gas calculated as follows. - Subject works:
- Capacities of cartridges 10 cc, 50 cc, 95 cc.
- Values of propellant force:
- (criterion is total weight) 10 cc-30 g, 50 cc-150 g, 95 cc-270 g.
- Working temperatures: 20°C, 100°C, 150°C.
- Subject gas:
- Carbonic acid gas (C02) (charging ratio) 1.34 Calculation (provided that P: pressure Kg/cm2,
- d: diameter mm,
- f: initial quantity of flow I/s and charging ratio 1.34)
- d: diameter mm,
- f: initial quantity of flow 1/s and charging ratio
- 1.34)From the above calculation, the diameter of the
orifice 31 is deduced as follows. - It will be understood that the diameter of the
orifice 31 required to avoid the cartridge taking off, even if the sealing plate is broken by a rise in temperature, varies in accordance with the weight of the cartridge though it is not limited to the conclusions of the foregoing calculation if the gas and the charging ratio are charged. - As regulation of gas flow when the inner pressure rises excessively is left to a crack through the
recess 21, the diameter of theorifice 31 of theregulator 3 and the size of the interstices of the filter can be selected so that they can secure effective quantity of gas flow at the usual temperature. - Having regard to a charging time, the diameter is about 0.6 mm in the case of 0.3 mm2 as an example among sectional areas of the orifice from 0.03-0.3 mm2, which are cited by the inventor. According to experiments by the inventor, the time spent for charging approximately 60 g of C02 gas in a cartridge having a capacity of 95 cc was about 3.4 seconds, where the diameter of the orifice was 0.6 mm, and was 1.4 seconds in the case of a cartridge which embodied the present invention in which the gas is charged through the
clearance 32 between theregulator 3 and the body 1. Indeed the gas has been charged more quickly by the order of 2.4 times or more.
