Definitions

  • the invention is related to a pressure container of the type comprising an inner fluid-tight liner and a pressure sup- porting layer outside the liner, as well as an outer, protective casing.
  • the liner and said layer as known per se consist of transparent or translucent materials
  • the casing comprises a middle section having surface portions being cut-away so that parts of the actual container, being located inside the casing, are visible externally, and that the casing has shock-absorbent properties.
  • the liner or inner layer can be manufactured by methods known per se, in particular blow-moulding as one piece or injection moulding in two or more parts to be assembled.
  • the particular form of casing comprised by the invention can also be produced by injection moulding, possibly in two or three separate parts being then assembled into an integral structure.
  • the casing structure has shock-absorbent properties, provided for by a suitable choice of materials and/or the actual configu- ration of the casing.
  • the pressure container according to the invention having a casing as stated above, has substantial advantages, in particular in consideration of two important factors with respect to this type of pressure containers, where there is involved a filling of a fluid in liquid phase, such as propane, to be delivered to a consumer appliance or the like upon vaporization in the pressure container.
  • a fluid in liquid phase such as propane
  • it is of much interest to the users to be able to observe the liquid level in the container which is possible when this consists of transparent or translucent materials.
  • the cut-away portions of the casing makes it pos- sible to observe the liquid level. Besides these portions will involve a "Venetian blind" effect, that in strong sun radiation prevents a too intense heating of the actual pressure container.
  • the configuration of the casing with the cut-away portions enable an air flow from the outside and over the actual container surface, so that the required heat can be supplied thereto for the varorization mentioned above.
  • This latter and highly desir- able effect will be particularly enhanced when at least the preferably cylindrical middle section of the casing, according to a preferred embodiment of the invention, is designed with spacer elements so as to form air flow passages between the container surface and the casing in general .
  • the air flow passages are adapted to extend in a generally vertical direction when the pressure container has a normal, standing position resting on the bottom and with the axis of the cylindrical section oriented substantially vertically.
  • Fig. 1 in axial section shows a pressure container ac- cording to the invention, e.g. for use as a propane bottle
  • Fig. 2 shows the actual container in the example of Fig.
  • FIG. 3 in exploded perspective view shows three sections of the casing for the container in Fig. 1,
  • Fig. 4 shows a cylindrical middle section of a casing for a larger (higher) pressure container than the one found in Figs . 1 and 2
  • Fig. 5 shows another and preferred form of protective casing in elevation
  • Fig. 6 in partial view shows a further embodiment of the protective casing
  • Fig. 7 in partial cut-away elevation shows an advantageous design of a bottom section for the pressure container
  • Fig. 8 at a smaller scale shows the bottom section in
  • Fig. 7 shows a first alternative bottom section to the one in Fig. 8
  • Fig. 10 shows a second alternative bottom section
  • Fig. 11 shows a third alternative design of a bottom section for the pressure container
  • Fig. 12 in perspective view shows an advantageous design of a boss at the top of the pressure container.
  • the actual container, which is manufactured for a desired volume capacity, in Figs. 1 and 2 is indicated with reference numeral 3.
  • the container 3 comprises an inner layer or liner 1, in the first place adapted to be a fluid-tight layer so that the contents can not escape from the container, even when being under comparatively high pressure.
  • a reinforcing or pressure-supporting layer 2 being here provided by means of winding fibre reinforced elements, such as glas fibres to which there has been applied a suitable adhesive or the like, for subsequent curing in the form of a number of winding layers on the liner 1.
  • winding fibre reinforced elements such as glas fibres to which there has been applied a suitable adhesive or the like
  • the casing 5 shown comprises a middle section 7 being preferably of a generally cylindrical shape, a top section 8 and a bottom section 9. As indicated in Fig. 3 these three sections can be produced separately and then be assembled into a more or less integrated, total structure constituting the casing 5.
  • sections 7 and 9 can be manufactured integrally as one piece, e.g. by injection moulding, and subsequently be joined to the top section 8 when the actual container 3 has been put into the middle section 7.
  • Another alternative consists in producing sections 7 and 8 integrated as one piece, with subsequent joining to the bottom section 9. Taking into account, inter alia, a rational production, the casing can also as a whole in its basic shape deviate more or less from the basic shape of the container within it.
  • the middle section 7 is built up by a number of ribbonlike elements of which two are indicated at 7E and 7F, extending around the whole circumference of section 7 and having a spacing in axial direction, as indicated e.g. at 7A, 7B and 7C.
  • These spaces form the cut-away surface portions mentioned above, that make it possible to observe parts of the actual container 3 inside the casing, in particular for the purpose of seeing the liquid level in the container.
  • the cut-away portions or spaces 7A, 7B and 7C have a substantially larger dimension in the lateral direction than in the height direction.
  • This design is also favourable in view of the Venetian blind effect mentioned above, i.e. a shading effect against undesired solar heating.
  • the cut-away portions constitute a relatively significant proportion of the total surface. It has been found that the proportion of cut-away surface portions should be at least 20% of the total exterior surface of the casing.
  • middle section 7 On the inside of middle section 7 there is provided a number of projections, ribs or webs adapted to form relatively wide air gaps between the outer surface of container 3 and the main parts of the adjacent casing. Such ribs or webs are shown at 14 and 15 in Fig. 1, and an additional example is illustrated at 16 in Fig. 3. As will appear from this figure there is a relatively high number of such projecting ribs around the whole circumference interiorly of middle section 7. In this way there are formed air gaps that make possible air flows, in particular in vertical direction as indicated with arrow 20 in Fig. l.
  • Such a resilient structure can also be useful in the case of expansion of container 3, e.g. during filling to a certain overpressure, or in the case of different heat expansion of the container and the casing 7 during temperature changes. It is obvious Ul J to t H F»

  • top section 8 and supporting or engagement members around the bottom of bottom section 9 can be formed as hollow structures as known per se, with e.g. an open or foam-like core, so as to sustain mechanical stresses that will occur during practical use of such pressure containers .
  • a nut-like part 4A that can e.g. have a hexagonal shape, which by the strong anchoring of the boss structure at the top of the actual container 3 , implies that this and nut-part 4A are rotationally securely interconnected.
  • the nut-part 4A thus can be favourably utilized. Thereby the users of such pressure containers will not be dependent on a secure rotational anchoring of the casing structure described, outside the actual pressure container.
