Definitions

  • a device for holding and discharging liquid and pastelike substances has a rigid outer container and a flexible inner container. The upper edge of the inner container is fastened to the outer container. The inner container is intended for holding the substance to be discharged, a discharge valve being in communication with the inner container. A propellant is introduced into the space between the containers for exerting pressure on the inner container. For assuring complete removal of the substance held in the inner container, and complete collapsing of the inner container, the peripheral wall of the latter is provided with longitudinal deformations in the form of recesses or depressions.
  • the invention relates to a device for holding and dispensing liquid and paste-like substances under pressure, comprising a rigid outer container and a flexible, preferably aluminum, inner container whose upper edge is fastened to the outer container, and having a discharge valve disposed in the top of the outer container and protruding into the'inner container and'a sealable opening in the base of the outer container for the introduction of a propellant.
  • the resilient inner container contains the useful goods while the annular space between theinner and the outer containers is filled with the propellant,- i.e. with pressurised gas.
  • the useful goods can be, for example, cosmetics, a perfume spray, an insecticide, lacquer or even a paste-like foodstuff such as liversausage or honey.
  • the discharge valve which may be fitted'with a spray nozzle, is opened, for example, by pressing or tilting. The pressure exerted by the propellant on the inner container takes effect and forces the useful goods out of the inner container through the discharge valve.
  • a previously proposed method of avoiding these difficulties is the use of distance bars which extend from top to bottom in the innercontainer and end above its base. These distance bars prevent the inner container from becoming completely constricted. However, there is the risk that, if the base of the inner container folds upwards, it may be pierced by the distance bar. This too immediately renders the entire device useless and the goods still contained in it are lost.
  • frame-like spreading rings have also been inserted into the inner container. These spreading rings cannot pierce the inner container. However, they do not prevent the inner container from becoming completely constricted at every point so that a pocket filled with the useful goods can still arise below the constriction. The goods contained in this pocket cannot pass the constriction and remain in the inner container. Such goods are lost. The useful life of the device is reduced accordingly.
  • the invention sets out to'provide a device such that the inner container does not become constricted to form a pocket which cannot be emptied or cracked along sharp bending or buckling lines, and does not become pierced by a distance bar, but is such that it can discharge its entire content of useful goods down to substantially the last drop through the discharge valve without there being any risk of the inner container folding sharply and as a result cracking.
  • longitudinal deformations are'provided equally distributed round theperipheral wall of-the inner container.
  • the deformation are formed by recesses.
  • these recesses preferably have the form of hollow depressions which look like gently sloping valleys.
  • the inner container does not apply the same resistence against the external pressure of the propellant on the surface of these depressions as it' does on the surface between these depressions, where as before it is circular shaped.'This means that the inner container is preformed and weakened in advance on the surface of its depressions so that the pressure of the propellant affects this part first of all.
  • the inner container is compressed uniformly over the surface area of these depressions which is large compared to the surface area of a "buckling line. The possibility of a buckle or fold along a' sharp edge which could lead to cracking is minimized. It is just as unlikely that the inner container will become constricted at any plane.
  • the large surface of the depressions is sufficient for the pressure of the propellant to act on. It is no longer possible, when the discharge valve is suddenly opened, for the resulting alteration in pressure to affect only a limited surface of the inner container and compress or constrict it there.
  • the depressions can end a short distance above the base and below the upper edge of the inner container.
  • FIG. 1 is a longitudinal section of a dispenser according to the invention; and I FIG. 2 is a cross section along the line 22 of FIG. 1.
  • the dispenser shown in FIG. 1 has a rigid outer container 12 with a base 14 and a filling valve 16 disposed -in an opening in the base for the introduction of the propellant.
  • a rigid outer container 12 Inside the rigid outer container 12 is a flexible inner container 18.
  • the upper edge of the inner container 18 is flanged round the upper edge of the outer container 12 and is held there by an outer container cap 20.
  • a discharge valve 22 is located in this outer container cap 20.
  • Four longitudinal depressions 24 are constructed in the wall of the inner container 18.
  • FIG. 1 shows that these depressions begin slightly above the base 26 of the inner container 18 and end shortly below the upper edge of the inner and outer containers. As can be seen particularly clearly in the transverse cross-section shown in FIG. 2, the depressions 24 look like gently sloping valleys.
  • the annular cavity between the outer container 12 and the inner container 18 and the space between the base 26 of the inner container 18 and the base 14 of the outer container 12 is filled with propellant through the filling valve 16.
  • the flexible inner container 18 is, therefore, under the pressure of this propellant. Its interior is filled with the useful goods.
  • the discharge valve 22 When the discharge valve 22 is actuated, the pressure of the propellant acts firstly on the surfaces of the depressions 24 as can be guessed from the section shown in FIG. 2. While the goods are being discharged through the discharge valve 22 the inner container gradually folds inwards on the surface of its four depressions 24. Finally, it assumes the approximate shape of a star. This star has the same section throughout the entire length of the inner container so that the contents too have left the inner container uniformly and smoothly.
  • a device for storing and discharging fluid and paste-like substances comprising a rigid outer container and a generally cylindrical, flexible metal inner container having inner and outer surfaces and positioned'within said outer container to define a space therebetween, pressure means in said space, and discharge valve means communicating with said metal inner container, said device being operative upon actuation of said discharge valve means to discharge contents of said metal inner container under the action of said pressure means thereon, said pressure means collapsing said metal inner container as the contents thereof are discharged, the improvement comprising: longitudinal weakening deformations of arcuate crosssection formed in said metal inner container to-cause said pressure means, upon actuation of said discharge valve means, to fold said metal inner container inward by said action of said pressure means on the outer surfaces of said longitudinal weakening deformations in preference to the remainder of said outer surface of said metal inner container.
  • a device as claimedin claim 1 in which four longitudinal weakening deformations are provided, offset at relative to one another.
  • said metal inner container comprises a base and an upper edge, and in which said longitudinal weakening deformations end slightly above said base and slightly below said upper edge of said metal inner container.
