Definitions

  • the invention relates to a two-chamber compressed gas pack, essentially consisting of a can body and a bellows with a bottom and a flexible collar that is turned inside the can body during movement, and a method for its production (WO 82/01176).
  • a two-chamber pressurized gas pack is a container for holding and dispensing liquid and pasty products under pressure and consists of a rigid, mostly metallic outer container, the can body, in which a bellows with a rigid bottom and an invertible collar is attached in such a way that two chambers are formed, one being filled with the removal product and the other being filled with a propellant gas or a pressure-generating liquid under increased pressure.
  • the propellant gas is relieved of pressure via a valve on the product side, which allows product to flow out of the pack when actuated.
  • Such containers have the advantage over the known spray cans that the propellant which expels the product remains in the container and, moreover, does not come into contact with the product. The latter circumstance is of particular importance if the product is a food, cosmetic or medicinal product.
  • WO 82/01176 describes a two-chamber pressurized gas pack consisting of a can body, a bellows in the bottom and an invertible collar. For the intended handling of this pack, the floor must be flexible.
  • the two-chamber pressurized gas packs according to the prior art presented have the major disadvantages that multipart can bodies are absolutely necessary and / or that the inserted support ring builds up a very large frictional force which hinders the application of the product due to a lack of differential pressure between the chambers. In addition, the material expenditure of the bellows and possibly the support ring is considerable.
  • the inventors have therefore set themselves the task of designing a two-chamber compressed gas pack which does not have such disadvantages and of developing processes for its production.
  • the first part of the object is achieved by the features specified in claim 1 for the subject matter of the invention and by their advantageous developments according to claim 2.
  • the object is achieved according to the invention with the features of claim 3.
  • the two-chamber compressed gas pack according to the invention is thus characterized in that not only the collar end is used to seal the chambers, with the effect that the collar can collapse radially. Furthermore the sealing surface is large, at least during the period in which the compressed gas pack still contains large amounts of product and the propellant pressure is still very high - at least larger than in the case of the seal according to the prior art presented - so that small deformations of the cylindrical Body of the pressurized gas pack without affecting the tightness of the collapsed during movement during handling of the pack remains.
  • the can body can be produced in a manner known per se from the materials usually used for this purpose.
  • plastics and ductile metallic materials and / or their composites are used - e.g. an injection-molded plastic blank, the wall of which is thinned out by thermoforming, thermoformed plastic composite, deep-drawn and / or stretch-drawn aluminum-plastic composite, or in particular an extruded, soft-annealed and internally varnished sleeve with a base that may have a secondary molding element, with the last two options using the open, product-facing element At the end, an outward doubling of the collar can be provided - for use.
  • the two-chamber compressed gas pack consists of a can body 10 with a base 6 containing a valve 5 and a valve plate 9 fastened by a rolled edge 7 and containing a product removal valve 8.
  • a bellows 20 with a rigid base 23, to which an annular or otherwise shaped secondary molded element 2 is molded can be, and contain collar 21.
  • the collar 21, which is made of flexible material, is fastened with its entire lateral surface to the inner wall 11 of the can body 10. The attachment can take place, for example, by friction and / or positive locking or with the aid of an adhesive 30.
  • Fig. 2 shows a possibility of attachment.
  • the bellows 20 with an outer diameter that is slightly smaller than the inside diameter of the can body is inserted into the can body 10 and then the can body 10 is reduced in diameter at least in the jacket region of the collar 21 by a pull-in ring 60 with a conical inlet 61 and thereby shrunk onto the bellows 10.
  • This particularly suitable method is preferably used when both the can body 10 and the bellows 20 consist of metal, in particular an aluminum material.
  • a further possibility is that the collar 21 is connected to the inner wall 11 of the can body 10 in that, by applying pressure via corresponding feeds 47 to the wall 46 facing the inside of the collar 21, an expansion mandrel 45 inserted into the can body 10 before the valve disk 9 is assembled the collar 21 is pressed onto the inner wall 11 of the can body 10.
  • the collar 21 and the inner wall 11 of the can body 10 are attached by plugging the bellows 20 onto a mandrel 40 in the region of the collar 21 which is slightly smaller than the inner diameter of the bellows, when using a Contact adhesive is at room temperature, when using a hot melt it is preheated - insert this part arrangement before installing the Valve plates 9 in the can body 10 and subsequent rolling of a roller 50 rotatably arranged on a shaft 51 on the outer wall 13 of the can body 10 in the peripheral region of the collar 21 connected.
