Definitions

  • the invention relates to a device for producing and spraying one of at least two components, for. B liquids, and a mixture of propellant according to the preamble of claim 1.
  • Such a device is known in principle from US-A-3 635 261 (Figs. 5 to 7), the outer container comprising two separate chambers, one of which is formed between the inner container and the bottom of the outer container .
  • This includes a pressurized gas filling.
  • a fluid connection between the compressed gas chamber and the inner container can be established with a break-up mandrel already introduced in the bottom of the outer container, the predetermined breaking point on the bottom side being opened with the break-up mandrel for this purpose.
  • the compressed gas then entering the inner container and the excess pressure building up there breaks up a relatively large-area membrane opposite the predetermined breaking point on the bottom, so that a fluid connection is established between the inner container and the second chamber of the outer container.
  • the present invention has for its object to provide a device of the type mentioned, in which a permanent seal between the interior of the outer container and the environment is guaranteed, and in which a sufficient fluid seal between the interior of the outer container and the environment also is maintained during use.
  • the axial guide bore associated with the hole in the bottom of the outer container is closed on the inside of the container by a closure membrane, a permanent fluid seal between the inside of the outer container and the environment is ensured before use.
  • This fluid seal is not interrupted in use, since according to the invention the axial extent of the fluid passage in the hole is smaller than the length of the axial guide bore in the bottom of the outer container.
  • the perforator designed in this way in combination with the membrane-sealed axial guide for the perforator in the bottom of the outer container, allows a fluid connection between the inner and outer container to be established without the risk of the components accidentally escaping into the environment.
  • the device or the two-chamber container according to FIG. 1 comprises an outer standard aerosol container 1 with an aerosol dispensing valve 3, which is held in a conventional manner in a lid 30 tightly attached to the opening edge 29 of the container 1 and an inner container 2 consists of an equally corrosion-resistant material as the outer container 1.
  • the outer container 1 contains a filling component A
  • the inner container 2 contains a filling component B and a suitable propellant T, which is generally an easily liquefiable gas, eg Butane-propane or the like.
  • the inner filling component B can e.g. Hydrogen peroxide and the filling component A can be a dye.
  • the dimensions of the containers 1 and 2 depend on the volume of the product to be dispensed and their ratio.
  • the maximum diameter of the inner container 2 can be just as large as that of the opening edge 29 of the outer container 1, so that the inner container 2 can still be inserted into the outer container 1 through this opening. These dimensions are standardized for common sizes.
  • the dispensing valve 3 fastened in the cover 30 consists of a valve body 31 and an actuating or dispensing tube 13 which is axially movable in this, through which the mixture can be removed from the interior of the outer container 1.
  • the dispensing tube 13 can be moved axially inward against the action of a helical spring 32, the helical spring 32 being supported on the valve body 31 on the one hand and on an annular shoulder 33 formed on the dispensing tube 13 on the other hand.
  • the valve body 31 is anchored in the cover 30 in a positive and non-positive manner, as can be seen very well in FIG. 1.
  • the inner container 2 is also choose via a support 4 in both the axial, radial and lateral directions supports.
  • the support 4 is preferably designed as a spring element acting in the axial direction, which presses the inner container 2 against a lower container support 5.
  • the inner container 2 is arranged with a bottle-neck-like opening 20 facing downward inside the outer container 1.
  • the bottle neck-like opening 20 is by means of a plug 7 made of plastic, rubber or the like. closed, the plug 7 being hat-shaped and fixed with its outer edge 34 between the edge 35 of the opening 20 of the inner container 2 and the container support 5 (see FIG. 2).
  • the closure plug 7 comprises a membrane 11 which closes the opening 20 and which is preferably of somewhat thinner wall than the remaining part of the closure plug 7 and which in the embodiment shown is delimited by a notch ring 21 for easier breaking open. As a result, a predetermined breaking point in the inner plug 7 is obtained.
  • the membrane 11 can be broken open from the outside by means of a breaking element which acts through the bottom 14 of the outer container 1 to produce a fluid connection between the inner and outer container, the breaking element in the embodiment according to FIGS. 1 to 5 being penetrated by a pin-like hole 9 is formed with an approximately circular cross section (see Fig. 3a and 3b).
  • the pin or bolt-like hole 9 is while maintaining a fluid seal between the interior of the outer container and the environment by a plug 8 arranged in the bottom 14 of the outer container 1 made of rubber, plastic or the like. corrosion-resistant material, can be pushed through, as can be seen very well in FIGS. 3 and 4.
  • the plug 8 also has a thin-walled membrane 22, optionally delimited by a notch ring, which can be pushed open through the hole 9 in the embodiment according to FIGS. 3 and 4.
  • the membrane 22 is located on the inside of the container of an axial guide for the hole 9, which is designed as a blind bore 23 with an inner diameter corresponding to the outer diameter of the hole 9. Furthermore, the membrane 22 of the outer plug 8 is aligned with the membrane 11 of the inner plug 7.
  • the hole 9 has a passage for the exit of the component B located in the inner container 2 together with the propellant gas T from it into the interior of the outer container 1, in the form of a longitudinal groove 12, the axial extent D of which is smaller than the length L of the Blind bore 23 in the outer plug 8.
  • the two-chamber container is preferably provided in the state shown in FIG. 2.
  • the punch 9 is thus inserted into the bore 23 up to the stop on the membrane 22.
  • an outer protective cap 10 is provided, which is placed or pushed onto the bottom end of the outer container 1.
  • the required spacing of the end wall 36 of the protective cap 10 from the bottom 14 of the outer container 1 is achieved by means of longitudinal ribs 37 arranged, preferably integrally formed, within the protective cap 10.
  • the inner container 2 is supported in the bottom region of the outer container 1 on the outer plug 8 both axially and laterally, namely via the support element 5, which has a cup-shaped receptacle 38 for the lower part of the inner container 2 and with the part projecting into the interior of the container of the closure plug 8 has cooperating centering ribs 6, at least three centering ribs 6 being provided distributed uniformly over the circumference.
  • a pressure plate 39 at its end protruding from the outer container 1 or the outer plug 8.
  • Fig. 4 the punch is shown in the fully pressed state. Both the membrane 22 of the outer plug 8 and the membrane 11 of the inner plug 7 are broken. Through the longitudinal groove 12, the filling component B can emerge from the interior of the inner container 2 into the interior of the outer container 1 (see arrows 40) and mix with the component A.
  • the plug 7 of the inner container is an integral part of the lower support 5, i.e. Sealing plug 7 and support 5 form a one-piece component. Furthermore, the end of the hole 9 inside the container can be made somewhat pointed to facilitate the breaking open of both the membrane 22 and the membrane 11.
