Definitions

  • CONTAINER FOR STORING GAS UNDER PRESSURE AND HANDLING CAP FOR SUCH A CONTAINER
  • the invention relates to an assembly of a container for storing liquefied, compressed or dissolved gas, under pressure, which assembly includes a flange, particularly for the mounting a valve and a handling cap fitted with means for fixing to the flange of the container.
  • the invention relates more particularly, but not exclusively, to containers consisting of portable bottles for storing liquefied petroleum gas.
  • containers consisting of portable bottles for storing liquefied petroleum gas.
  • the words "container” and “bottle” will be used indifferently.
  • Such an assembly demands a certain number of operations on the part of the users for bringing the containers into service and replacing them. This is especially the case where bottles for liquefied petroleum gas, butane or propane are used domestically in combination with a cooking apparatus.
  • Fixing the handling cap on the bottle is conventionally achieved by screwing the handling cap onto the flange of the bottle, which flange is thereto threaded.
  • the conventional arrangement has a certain number of drawbacks: the engaging of the handling cap on the flange is not very convenient and is difficult to automate; there is a risk of seizure at the end of screwing-in and, in the other direction, a difficulty in unscrewing the handling cap which creates a need for lubrication to make rotation easier, and a contact which soils the hands of the user; progressive wearing of the screw thread leads to an increasing amount of play which may, in time, compromise the secureness of the fixing.
  • the assembly of a container for storing liquefied, compressed or dissolved gas, under pressure, including a flange, particularly for the mounting a valve and a handling cap fitted with means for fixing to the flange of the container according to the present invention is characterized in that the flange on its external perimeter includes at least one slot directed radially inwards, and in that the means for fixing the handling cap comprise, on the one hand, at least one locking element which can move radially in order to interact with the slot in the flange and, on the other hand, a means for controlling the radial position of this (these) locking element (s) to make it possible quickly either to fix the handling cap on the container or to release the handling cap therefrom.
  • the slot in the flange consists of an annular groove running right around the flange so that the fixing of the handling cap to the container is achieved with the possibility of rotating the handling cap about the central longitudinal axis of the flange.
  • the locking element or elements advantageously consist (s) of (a) ball(s) .
  • the handling cap includes a cylindrical base capable of surrounding the flange of the container and this cylindrical base includes holes passing radially through it to take the locking elements with the possibility of a radial displacement of these elements .
  • the diameter of the holes, at the interior surface of the cylindrical base is preferably smaller than the diameter of the balls, particularly via a restriction made at the exit orifice of the hole, to ensure that the ball is retained in the hole, while allowing this ball to project inwards over a distance sufficient to interact with the groove and provide fixing.
  • the groove of the flange may have a square cross section, open radially towards the outside.
  • the means for controlling the radial position of the locking elements is advantageously mounted so that it can rotate about the cylindrical base of the handling cap.
  • control means comprises a ring with a central opening in which the cylindrical base of the handling cap is engaged, the internal wall of this central opening including notches which can be placed in line with the holes of the cylindrical base to allow the locking elements to retract and to come out of the groove with release of the handling cap, while the regions of the internal wall of this ring other than the notches are capable of retaining the locking elements and keeping them projecting into the groove.
  • the ring is held in translation in the axial direction of the cylindrical base of the handling cap, particularly by snap-fastening.
  • Reciprocal stops are provided on the ring and on the handling cap in order to define a first angular position corresponding to engagement of the locking elements in the housing of the flange, and a second angular position corresponding to the release of the bonnet and the notches of the ring coming in line with the holes in the base of the handling cap.
  • the ring includes four corresponding notches, substantially in the form of obtuse-angled recesses.
  • an elastic means particularly a torsion spring, is provided for returning the ring to the first angular position against the handling cap, corresponding to the fixing of the handling cap on the container.
  • the operator may bring the ring into the second limit stop position, for releasing the handling cap, the ring returning to its first position as soon as the user lets go of it.
  • the handling cap preferably comprises two substantially diametrically opposed uprights stretching upwards from the cylindrical base, these uprights being joined at the top by a type of frame with a substantially rectangular closed contour, off-centred with respect to the central longitudinal axis of the cylindrical base of the handling cap; the short side of this contour furthest from the central longitudinal axis of the handling cap forms the main handle, while the opposite short side forms an auxiliary handle; there are apertures between these handles and the cylindrical base of the handling cap, the aperture available between the auxiliary handle and the base of the handling cap being sufficient to allow access to the valve of the container for filling this container or fitting a pressure-reducing valve without it being necessary to remove the handling cap from the container.
  • the control ring preferably comprises a radial extension to make it easier to rotate it; advantageously, this radial extension is situated on the same side as the main handle with respect to the cylindrical base of the handling cap.
  • the invention also relates to a container for storing compressed or dissolved liquefied gas, under pressure, particularly a portable bottle of liquefied petroleum gas, including a flange for the mounting of a valve, this container being characterized in that the flange on its external perimeter includes at least one slot directed radially inwards.
  • the slot of the flange consists of an annular groove stretching around the entire perimeter of the flange.
  • the invention also relates to a handling cap for handling a container for storing liquefied, compressed or dissolved gas, under pressure, this handling cap being fitted with means for fixing on the flange of the container and being characterized in that these fixing means comprise, on the one hand, at least one locking element which can move radially relative to the base of the handling cap and, on the other hand, a means for controlling the radial position of this (these) locking element (s) to allow quick fixing the handling cap onto the container or releasing it from the container.
  • the locking elements consist of balls.
  • the handling cap in general includes a cylindrical base capable of surrounding the flange of the container, and this cylindrical base includes holes passing through it, oriented radially, to take the locking elements with the possibility of radial displacement.
  • Figure 1 of these drawings is a view in vertical section of the assembly of a bottle for liquefied petroleum gas, only the upper part of which has been represented, and a handling cap being arranged on the bottle, the handling cap being sectioned on two angularly offset planes.
  • Figure 2 is a horizontal section on the line II-II of Figure 1.
  • Figure 3 is a vertical section through the cap body on the line III-III of Figure 1, the ring and the balls not being represented in this figure.
  • Figure 4 is a perspective view, on a smaller scale, of the ring of the handling cap.
  • Figure 5 is a section, on a larger scale, of the ring on the line V-V of Figure 6.
  • Figure 6 is a view from above of the control ring.
  • Figure 7 is a view from below, with parts cut away, of the handling cap equipped with the balls and with the ring, in the locked position.
  • Figure 8 in a similar way to Figure 7, with parts cut away, shows the handling cap with the ring in the unlocked position.
  • Figure 9 is a diagram illustrating the carrying of a bottle equipped with a handling cap according to the invention.
  • FIG. 1 of the drawings it is possible to see the assembly of a container for storing liquefied gas, consisting of a portable bottle 1 of liquefied petroleum gas and a handling cap 2 for handling this bottle 1.
  • the upper part of the bottle 1, the only part represented, has the conventional shape of a convex dome and at its top includes a flange 3 fitted with a tapped hole 4 for the mounting a valve, not shown.
  • the bottle 1, as shown in Figure 1, is assumed to be empty. It should simply be noted that the valve mounted in the tapped hole 4 has a maximum diameter which is smaller than the outside diameter of the flange 3 so that a handling cap arranged over the flange 3 can also be arranged over the valve mounted in the tapped hole 4.
  • the flange 3 is welded to the wall of the bottle 1.
  • the handling cap 2 can be mounted on that part of the flange 3 which projects outwards, relative to the wall of the bottle 1. To this end that part of the flange 3 includes a slot directed radially inwards in the form of an annular groove 5 stretching around the entire periphery of the flange 3.
  • This groove 5 preferably has a square transverse section, open radially towards the outside. That part of the flange 3 which is situated above the groove 5 ends in a frustoconical chamfer 6.
  • the handling cap 2 comprises a cap body 2a fitted with fixing means F for fixing it to the flange 3.
  • These fixing means F comprise, on the one hand, at least one and preferably several locking elements consisting of balls 7 which can move radially relative to the cylindrical base 8 of the handling cap 2 and, on the other hand, a means C for controlling the radial position of the locking elements 7 to allow either the rapid fixing or the rapid release of the handling cap 2.
  • the cylindrical base 8 of the handling cap 2 is so designed as to surround the flange 3 of the container 1.
  • This base 8 includes holes 9 (see Figure 3) passing through it, oriented radially, to take the balls 7 with the possibility of radial displacement.
  • four holes 9 uniformly spaced by 90° are provided in the base 8 and four balls 7 are housed in these holes 9.
  • the diameter of the holes 9 is equal, to within an operating clearance, to that of the balls 7.
  • the orifice 10 constituting the radially internal end of the holes 9, following a restriction has a diameter slightly smaller than that of the ball 7 which is thus prevented from coming completely out of the hole 9 towards the inside.
  • the ball 7 When the ball 7 is resting against the restriction formed by the orifice 10, it is projecting inwards, as shown in Figure 7, in the form of a spherical cup which is sufficiently large to interact with the walls of the groove 5.
  • the cap body 2a ( Figure 3) comprises two substantially diametrically opposed uprights 11, 12 stretching upwards from the cylindrical base 8. These uprights 11, 12 have substantially the shape of rectangular plates at the bottom part and their transverse dimension increases at the top. As visible in Figure 1, the edges of the upright 12, at the top, diverge until they connect with a frame 13 with substantially rectangular contour, the mid-plane of which is substantially orthogonal to the central longitudinal axis A. As visible in Figures 7 and 8, the contour of the frame 13 is off-centred with respect to the central longitudinal axis A and the short side of the frame 13 furthest from the central longitudinal axis A is arranged in the form of a main handle 14, while the opposite short side forms an auxiliary handle 15.
  • the transverse section of the main handle 14 (Figure 1) has a profile which is convex towards the inside making it easier to grasp hold of the handling cap and to handle the bottle. As visible in Figure 9, taking hold of the handling cap by the handle 14 causes an inclining of the carried bottle 1, the centre of gravity of which aligns itself vertically below the handle 14; this backwards inclination makes carrying easier. If need be, the auxiliary handle 15 may be used to help with the carrying of the bottle, either using two hands, or by two people.
  • the space inside the frame 13 is open. Furthermore, there are apertures 16, 17 between the handles 14, 15 and the cylindrical base 8. The aperture 17 provided between the auxiliary handle 15 closest to the central longitudinal axis A and the base 8 gives sufficient access to the valve (not represented, intended to be mounted in the tapped hole 4) to carry out the operations of filling the bottle 1 or of connecting a pressure- reducing valve, without it being necessary to remove the handling cap 2 from the bottle 1.
  • the means C for controlling the radial position of the balls 7 comprises a ring 18 mounted so that it can rotate about the cylindrical base 8 of the handling cap 2.
  • the ring 18 includes a central opening 19 (see Figures 4 to 6) bounded by a wall 20 snap-fastened into a groove 21 ( Figure 3) provided at the periphery of the cylindrical base 8. The ring 18 is thus held in terms of translation relative to the cap body 2a.
  • the exterior surface of the cylindrical base 8 of the cap body at its lower end, has a chamfer 22 on its internal perimeter to make engagement on the flange 3 easier and, on its external perimeter, has a step 23 with a frustoconical surface, the diameter of which increases from the bottom upwards.
  • This step 23 towards the bottom bounds the groove 21 via a retaining wall situated in a plane orthogonal to the central longitudinal axis A and having a relatively small radial dimension to allow the snap-fastening of the ring 18.
  • Another wall 24, situated in a plane orthogonal to the central longitudinal axis A and of a larger dimension in the radial direction bounds the groove 21 at the top.
  • a cutout 25 at right angles follows on from the wall 24 towards the top, as visible in Figure 3.
  • the dimension of the groove 21 in the direction of the axis A is equal to h ( Figure 3) while the dimension of the cutout 25 in this same direction is equal to m, m generally being smaller than h.
  • the wall 20 of the ring 18, bordering the opening 19, has a thickness e -(see Figure 5) which is equal, to within an operating clearance, to the dimension h of the groove 21.
  • the wall 20 is bounded on its external perimeter by a flange 26 with a reduced radial thickness, projecting in a direction parallel to the axis of the ring 18 over a distance p. This distance p is equal to the distance m to within the operating clearance.
  • the wall 20 has a snap-fastening lip 28, the inside diameter of which is equal to the diameter of the groove 21.
  • the upper face 29 of this lip 28 is frustoconical flaring out upwards.
  • the wall 20 of the ring 18 includes notches 30 which are intended to be placed in line with the balls 7 to allow their radial displacement outwards and to allow them to come out of the groove 5, releasing the bonnet 2 relative to the flange 3.
  • notches 30 uniformly distributed around the circumference and therefore offset by 90° are provided.
  • Each notch 30 has a transverse section in the form of an obtuse angle, the vertex of which faces outwards.
  • the notches 30 are provided over the entire height of the wall 20 and intersect the lip 28, making it easier for the ring 18 to be deformed in order to overcome the step 23 during snap-fastening.
  • the notches are arranged to allow the balls 7 to come completely out of the groove 5 towards the outside, as shown in Figure 8, when they are placed in line with these balls.
  • the ring 18, as visible in Figures 4 to 6, includes an outward radial extension 31 with a substantially dovetail-shaped contour allowing the ring to be manoeuvred to make it turn about the central longitudinal axis A.
  • This extension 31 has a dimension in the direction of the axis of the ring greater than that of the wall 20 and of the flange 26 and protrudes upwards above the upper edge of the flange 26 by a distance d (see Figure 5) .
  • the extension 31 is integral with the ring 18 via a portion of cylindrical surface 32 including two extreme edges 33, 34 which are parallel to the axis of the ring 18 and arranged to act as limit stops in the positioning of this ring 18.
  • the cap body 2a includes mating stops 33a, 34a provided respectively on the substantially vertical edge of the uprights 11, 12 situated on the same side as the handle 14.
  • the stops 33, 33a by their interaction determine a first angular position of the ring 18 for which the balls 7 are in contact with the internal surface of the wall 20, substantially half the angular distance between two notches 30; the balls 7 are thus kept projecting radially inwards into the groove 5.
  • the stops 34 and 34a by their interaction illustrated in Figure 8, determine a second angular position of the ring 18, relative to the cap body 2a and to the base 8.
  • the elastic means R is provided for returning the ring 18, relative to the base, to the first position illustrated in Figure 7 corresponding to the fixing of the handling cap 2 on the flange 3.
  • the elastic means R advantageously consists of a torsion spring 35 surrounding the base 8 of the handling cap and housed in the space 27 (see Figure 1) .
  • the mid-plane of the spring 35 is orthogonal to the central longitudinal axis A of the base 8.
  • One end of this spring 35 is bent upwards at right angles to be anchored in a hole 36 ( Figure 7) provided in the horizontal face of the cutout 25 of the cap body 2a.
  • the other end of the spring 35 is bent downwards at right angles to be engaged in a through-hole 37 provided in the ring 18.
  • the spring 35 is preloaded and permanently acts upon the ring 18 so as to keep the limit stops 33 and 33a resting against each other, this corresponding to the fixing position of the ring 18 of Figure 7.
  • the ring 18 is then snap-fastened into the groove 21, at the same time ensuring a preloading of the spring 35 and ensuring the engagement of the other end of this spring in the hole 37.
  • the handling cap 2 is thus put together and the ring 18 can rotate between the two limit stop positions illustrated in Figures 7 and 8.
  • the aperture 17 can be placed in the position most favourable to access to the valve (not shown) mounted on the tapped hole 4, which allows the bottle 1 to be filled, or the fitting of a pressure- reducing valve, without having to remove the handling cap 2.
  • the extension 31 is provided on the opposite side to the aperture 17, to leave the space of this aperture completely free.
  • the radial extension 31 could be dimensioned so that it protrudes upwards by a distance d sufficient to prevent the pressure-reducing valve from being introduced via the aperture 16 and force it to be introduced via the aperture 17, for example when the configuration of the pressure-reducing valve would present a problem of space after being introduced by the aperture 16. This dimensioning of the radial extension 31 thus gives a biasing effect.
  • the bottle 1 is made easier to carry, as already explained with regard to Figure 9.
