Definitions
- Container with at least one chamber primarily defined by a tubular structure, tubular structure and method and arrangement for its production
- the present invention relates to a container with at least one chamber defined primarily by a tubular structure made of rubber-elastic material, which communicates at an output opening with at least one output valve for a filling material kept under pressure in the chamber due to the structure's own elasticity, and a tubular structure made of rubber-elastic material , to define a chamber which can be connected at an outlet opening to an outlet valve for a filling material kept under pressure in the chamber due to the inherent elasticity of the structure.
- the present invention relates to a method for producing such
- Propellant gas either in the product itself or, in the case of two-chamber cans, must be introduced into a chamber between a can housing and the inner chamber receiving the product.
- the structure has at least one section which extends over a substantial part of it Axial expansion extends, is designed to converge and / or that the wall thickness of the structure changes in the axial direction.
- the structure has at least one radially protruding collar in the area of the dispensing opening, and that this collar acts as a sealing member between the Lots is pressed.
- the section extends over, at least almost the entire axial extent of the structure.
- the entire axial length of the structure is used to achieve, with the conical design, a controlled, axially symmetrical expansion when filling or a controlled contraction to a largely known residual volume during emptying.
- the structure is preferably designed for itself or in the container such that the section is designed to converge in the direction pointing away from the dispensing opening. Then the wall thickness of the structure is preferably designed to decrease in this direction.
- this design also has the advantage that such a structure can be easily produced by the taper direction ensuring that the structure can be easily stripped off by a manufacturing tool.
- the structure can also be designed to be open at its end facing away from the dispensing opening, namely if, for example, a film bag is arranged within the structure to hold the filling material, it is preferably proposed that the structure be closed at its end facing away from the dispensing opening is, with which the structure itself forms the chamber and, inter alia, in the production of relatively complicated operations, by means of which the aforementioned film bag has to be inserted into the structure, are avoided.
- the wall thickness mentioned together with the selected material of the structure, determine the expansion / pressure properties of the structure and therefore, to ensure sufficient output pressure until the structure is practically completely empty, it must be made relatively thick, that the wall thickness of the above-mentioned sealing collar is made smaller compared to the wall thickness of the rest of the structure.
- the structure of the structure must be selected, for example for foods to be filled, in such a way that there is no influence on the taste, or in the case of aggressive contents such that the structure of the structure is not impaired, such as dissolution.
- the material costs for the wall material mentioned, and also the production costs for such a structure can be very different depending on the material to be used.
- the structure be internally coated or internally treated 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 account of the different filling goods with the inner coating or treatment of the structure mentioned.
- the term "coating" of the rubber-elastic material is used when an additional material is permanently applied to the rubber-elastic material.
- treatment is used here when the properties of the rubber-elastic material on the inner surface are changed in a way that is appropriate for the purpose. These two terms can flow smoothly into one another, since a treatment of the rubber-elastic material on its surface can also lead to the formation of a layer.
- a method for producing a tubular or stocking-shaped structure, such as the above-mentioned structure, in such a way that different properties of filling goods can be taken into account even when using a uniform rubber-elastic material is characterized according to the invention in that the rubber-elastic material is brought into a flowable state via one Applied mandrel and a coating medium before or after, detachable, applied over the mandrel or before or afterwards a treatment medium for targeted modification of the surface of the rubber-elastic material on the mandrel side.
- the rubber-elastic material is brought into a flowable state, applied via a mandrel, and then the applied material is expanded by applying pressure and introduces coating or treatment medium.
- the material is inflated, as in the case of use, detaches from the mandrel and the coating or treatment medium can be applied or used in the inflated state, that is to say, for example, on the largest internal area of the structure that occurs during use.
- a simple way to inflate the structure made of rubber-elastic material over the mandrel is to bring in the coating or treatment medium itself, driven by compressed gas, as dust or mist, with which the compressed gas inflates the structure, or by coating or Introduces the treatment medium under positive pressure in liquid form and retrieves it under negative pressure.
- a coating medium is first applied to the mandrel by immersion before the rubber-elastic material is introduced and then the coating medium and rubber-elastic material are treated, for example vulcanized, at the same time.
- 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 structural wall material, in the region of the mandrel, preferably at least at the end, at least one dispensing opening for a coating - or treatment medium is provided.
- the feed is designed for flowable, rubber-elastic material and that at least one pressure medium discharge opening opens out in the area of the dome, the opening communicating with a pressure source that is independent of a coating medium or treatment medium supply, or with a pressure source to promote the coating medium or the treatment medium.
- the dispensing opening for the coating or treatment medium comprises a spray nozzle.
- a simple embodiment results from the fact that the discharge opening for the medium communicates with a pressure source in order to press on the structure with the pressurized medium and at the same time to coat or treat it.
- a conveying medium such as compressed air
- the coating medium for example in the form of fog or dust
- the pressure medium for spreading the structure.
- at least one return opening for unapplied medium is provided in the area of the mandrel , so that medium can first be applied under pressure, whereby the structure is expanded and coated or treated at the same time and then the medium can be retrieved and at the same time the structure collapses again over the mandrel.
- the discharge and return opening are preferably formed together as an opening, and the pressure source can be controlled to deliver an excess pressure in a coating or treatment and possibly a dry phase, and then a reduced pressure with respect to the excess pressure, so that it is not applied Retrieve medium and let the structure collapse over the mandrel.

- the discharge and return opening communicate with a tank for liquid coating or treatment medium, and that the mandrel is arranged to hang vertically downward, that at least one vent opening is further preferably provided in the attachment area of the mandrel.
- 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 for fastening to 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 for fastening a chamber, such as a chamber formed by the above-described structure with a valve, to a carrier, such as to a can or bottle, is characterized in that it is detachable.
