Definitions

  • the invention relates to a container according to the preamble of claim 1 (known from US.A.3 083 871) and a tubular structure according to the preamble of claim 2 (known from US.A.3 907 169). Furthermore, the present invention relates to an arrangement and a method for producing such a structure (claims 14, 25, 26).
  • a container is known with a chamber surrounded by rubber-elastic material, which is stretched over a squeezer or a shape stabilizer as a support element.
  • This chamber can be designed as a rotationally symmetrical tube which is closed at the bottom and hangs below the valve on that support element with a curved surface and is stretched in the longitudinal direction in the interior of the outer container.
  • US-A-3,083,871 and US-A-4,222,499 each show a spray device with a cylinder container made of expandable rubber material which is fixed in a rigid outer vessel.
  • EP-A-0 100 422 shows an arrangement and a method for producing a structure made of elastic material using a mandrel for determining the inner contour of the structure (corresponds to the preamble of claims 14, 25, 26).
  • the inner and / or the outer circumferential surface of the wall of the structure arranged in the container should or should be designed to be axially converging in a section which extends from the dispensing opening to the closed end of the structure at least over the larger part of its axial extent. Protection is sought independently for such a structure if its wall thickness changes in the axial direction, preferably along the converging section, in particular changes continuously.
  • the structure in the section mentioned expands regularly axially symmetrically when the filling material is filled under pressure, thus ensuring an axial contraction even when the structure is emptied up to a well-defined residual internal volume of the structure.
  • the latter can preferably comprise a snap ring. This creates a simple seal between the structure and the actual can housing.
  • At least two structures are provided coaxially or next to one another, advantageously a chamber between the structure or structures and a container wall is intended to communicate with a valve.
  • the pressure required for stretching the structure can be influenced by the fact that indentations of thinner or thicker wall thicknesses are provided along the surface of the structure - which results in parts of different wall thickness in cross sections of the structure, distributed around its circumference - the above-mentioned manageability becomes Filling and emptying in the conical shape given according to the invention is already thereby achieved that at least almost the entire structure has a constant wall thickness and / or a preferably constantly changing wall thickness.
  • the wall thickness mentioned together with the selected building material, determine the expansion / pressure properties of the building and therefore, in order to ensure a sufficient output pressure until the building is practically completely empty, it must be made relatively thick, it is proposed that the wall thickness of the above-mentioned sealing collar, compared to the wall thickness of the rest of the structure, is formed smaller.
  • the wall thickness of the structure should change in the axial direction - preferably along the converging section - in particular change continuously, and the section should extend over at least almost the entire axial extent of the structure.
  • the wall thickness of the structure is preferably also designed to decrease in this direction.
  • this training also entails that such a structure can be easily produced; the direction of taper allows the structure to be easily stripped from a production tool.
  • the structure can also be designed to be open at its end facing away from the dispensing opening if, for example, a film bag is arranged within the structure to hold the filling material, the structure should be at its end the end facing away from the dispensing opening should preferably be closed and itself form the chamber; in this way, relatively complicated operations are avoided during manufacture, by means of which the above-mentioned film bag has to be inserted into the structure.
  • the structure material must be selected, for example in the case of foods to be filled, in such a way that there is no influence on the taste. In the case of aggressive filling goods, there must be no impairment, such as dissolution, of the building material.
  • the material costs for the wall material mentioned can be just as different as the production costs for such a structure.
  • the structure is preferably internally coated or internally treated or provided with an inner layer in order to adapt the chamber wall to the characteristics of a filling material independently of the rubber-elastic material. This makes it possible to use the same rubber-elastic material and thus also the same manufacturing process for practically all applications and only to take the different filling materials into account with the inner layer or treatment of the structure mentioned.
  • coating of the rubber-elastic material is referred to when an additional material is permanently applied to the rubber-elastic material, and “treatment” when the properties of the rubber-elastic material on the inner surface are changed appropriately. These two terms can flow smoothly into one another, since treating the rubber-elastic material on its surface can also lead to layer formation.
  • rubber-elastic material is applied in a flowable state to a mandrel and a detachable coating medium in front of or after it over the mandrel applied or introduced to specifically change the mandrel-side surface of the rubber-elastic material.
  • the rubber-elastic material is applied according to the invention in a flowable state via the mandrel in the manufacture of a stocking-type structure, and then the applied material is expanded by applying pressure and coating - or introduced treatment medium.
  • the material is inflated, as in the case of use, detaches from the mandrel, and the coating or treatment medium can be inflated, i.e. e.g. can be applied or used for the largest internal surface area of the building.
  • a simple way to inflate the structure made of rubber-elastic material over the mandrel results from the fact that the coating or treatment medium itself is driven by compressed gas as dust or mist, whereby the compressed gas inflates the structure. Or you bring the coating or treatment medium in liquid form under positive pressure and bring it back under negative pressure.
  • the coating medium can also be applied to the mandrel in a dipping process before the rubber-elastic material is introduced and then the coating medium and the rubber-elastic material are treated simultaneously, for example vulcanized.
  • An arrangement for producing a tubular or stocking-shaped structure for example for carrying out the above-mentioned method, has at least one mandrel in a chamber provided with at least one feed for wall material and in its area - preferably at least in the end - at least one dispensing opening for a coating - or treatment medium.
  • the feed is designed for fluidized rubber-elastic material and that at least one discharge opening for the pressure medium opens out in the region of the mandrel, which communicates with a pressure source that is independent of a feed for coating or treatment medium, or with one Pressure source to promote the coating or treatment medium.
  • a spray nozzle is proposed at the discharge opening for the coating or treatment medium.
  • the discharge opening for the medium communicates with a pressure source in order to press the structure onto the pressurized medium and simultaneously coat or treat it.
  • a conveying medium such as compressed air, by means of which the coating medium is conveyed, for example in the form of fog or dust, is simultaneously used as a pressure medium for spreading the structure.
  • At least one return opening for unapplied medium is provided in the region of the mandrel, so that medium is first applied under pressure - with which the structure is expanded and coated or treated at the same time - and then the medium can be retrieved , at the same time the structure collapses again over the mandrel.
  • the discharge and return opening are preferably designed together as an opening, and the pressure source is controllable for releasing an overpressure in a coating or treatment and possibly a drying phase, and then a pressure which is reduced with respect to the overpressure, in order to then retrieve unapplied medium and collapse the structure over the thorn.
  • sealing members for the structure are preferably provided in the base region of the mandrel.
  • the arrangement preferably has a rotary drive, at least for the mandrel, which thus acts either as a centrifuge to convey material applied to it outwards and, thanks to its conicity, to convey it upwards or downwards, or as a rotating spray head.
  • the discharge and return opening communicate with a tank for liquid coating or treatment medium, and that the mandrel is arranged so that it hangs vertically downward, that further preferably at least one vent opening is provided in the attachment area of the mandrel.
  • valve and structure must be attached to this shelf as a carrier on the one hand, and individually replaceable on the other. It may also be desirable to optionally provide containers with such a structure with a valve, which is conventionally not possible.
  • a structure of this type is now proposed, in which a releasable fastening arrangement is provided in the region of the dispensing opening in order to fasten the structure to a carrier, such as to an opening in a container.
  • the structure preferably has at least one annular collar in the region of the dispensing opening, which is clamped between a valve carrier part and an annular fastening arrangement.
  • the fastening arrangement is extremely simple in that it comprises a snap ring for fastening to an opening such as a bottle or can neck. Instead of a snap ring, a threaded lock or a bayonet lock or the like can also be provided.
  • An arrangement to attach a chamber formed by the above-described structure with a valve to a carrier such as a can or bottle should be designed to be detachable according to the invention, for example to attach to a container with an opening neck, preferably so that it has a snap ring for the neck closure.
  • At least two structures should be provided coaxially or next to one another in a container of the type mentioned at the beginning.
  • a chamber formed between the structures or between a structure and a wall of the container can now also communicate with a valve and thus for one of the contents be made usable by the pressure in the container being the same everywhere with a rigid outer wall of the container and elastic partition walls.
  • a sealing plastic film bag in the rubber-elastic stocking, which practically comes into direct contact with the filling material of the stocking instead of a coating and thus prevents any taste contamination of the goods by the material of the rubber-elastic stocking.
  • a stocking 1 according to the invention made of rubber-elastic material has a body 3 that is rotationally symmetrical with respect to an axis A and, inside, a receiving chamber 5 for a filling material.

  • a ventilation opening 31 is provided on the can 15 at any location - for example and as shown schematically on the floor - through which the air can escape from an intermediate chamber 17a between the housing 17 and the rubber-elastic stocking 1 when the stocking 1 is expanded. Thanks to the shape shown in FIG.
