Definitions

  • the invention relates to a spray can for dispensing a good from a spray nozzle.
  • the material can be released in the form of a fine mist, but also in the form of an atomized jet with larger drops.
  • such spray cans comprise a filling material container which holds the filling material, furthermore a valve unit connected to the filling material container and having a spray head which in turn has a spray nozzle.
  • the spray nozzle should generally be oriented in a certain direction; when pressure is applied by hand, there is often a deviation from this direction.
  • Another known type uses a container made of an elastomeric material as the filling material container. This material is stretchable. The filling container is stretched when the filling material is introduced ("loading"). Due to the inherent elastic force, it exerts pressure on the contents. When the valve is opened by applying slight pressure to the spray head, the product container itself drives one due to the elastic force mentioned
  • the invention has for its object to design a spray can with a product container made of elastic material such that the elastic force of the product container remains at least approximately constant over most of the life of the spray can, and in particular in the last phase, that is, when only a small amount of product is left in the product container, is sufficient to drive out the last remainder or at least most of it from the product container.
  • the residual amount in the product container should be as small as possible and the temperature dependence of the spray system should be minimal.
  • the product container Before the assembly of these two components, the product container has a smaller internal width than the outer diameter of the expansion body. The expansion body thus widens the product container during insertion. The product container thus encloses the expansion body tightly and under a certain tension.
  • the inventors have recognized that the stress-strain curve of the elastic material of the product container - when an optimal one is selected elastic material - runs at least approximately constant, so that the resilient force inherent in the product container remains the same regardless of its state of expansion, namely over a larger expansion range.
  • This has two advantages: The quality of the spray jet in terms of pressure and throughput is largely preserved over the life of the spray can. Furthermore, even towards the end of the life of the spray can, that is, if only a small quantity of filling material is still contained in the filling material container, contain a sufficiently large force in the material of the filling material container, so that a remaining quantity is largely or completely expelled from the filling material container ,
  • the expansion body can have the shape of a projectile and thus have a cylindrical shape on a large part of its outer surface.
  • the contour of the expansion body can have the shape of a projectile and thus have a cylindrical shape on a large part of its outer surface.
  • the inner wall of the product container can have the same shape.
  • the expansion body can be pushed forcibly into the product container, with the product container widening. This is a covering of the product container over the expansion body.
  • Another possibility is to widen the contents container with other means than with the aid of the expansion body.
  • Expansion body can then be easily inserted in the expanded state of the product container.
  • Any type of spray nozzle must of course have an opening for introducing the filling material, but also an opening for dispensing.
  • the valve mentioned is located in the opening for dispensing. This is opened by pressing the spray head - generally with the index finger.
  • the construction can be designed such that there is only a single valve. This serves both for filling the filling material container and for discharging filling material for the purpose of spraying.
  • the valve is a non-return valve which, during filling - without exerting pressure on the spray head - only allows the filling material to pass through in one direction, namely in the filling direction.
  • a particularly interesting embodiment consists in providing the expansion body with a channel which runs through the expansion body.
  • the channel can be passed in the axial direction through the expansion body over the entire length. If one imagines the shape of the filling container as sack-shaped, the channel would open into the expansion body in the area of the sack bottom. But it is also conceivable to provide the channel with side outlets, so that several sub-channels open on the inner wall of the product container. It is also advantageous for
  • the product container is made up of two or more layers.
  • the outer layer consists of chemically cross-linked elastomer or
  • the inner layer can consist of an inert material that does not form a connection with the contents and does not impair its quality.
  • silicone or silicone rubber can be used here.
  • One or more layers can also consist of thermoplastic elastomer (TPE).
  • a barrier layer can also be provided between an inner and an outer layer, which prevents the contents or components of the contents from diffusing through the contents container.
  • the outer layer need only partially enclose the inner layer or the inner layers.
  • the partially closed layer can take the form of a cage
  • expansion bodies can be provided. These can add up to a single expansion body, for example the shape of a
  • the expansion body can have ribs that run in the circumferential direction and that hinder a flat contact against the inner surface of the product container.
  • the expansion body can have extensions at one or both ends, for example in the form of a spider, with which the expansion body is held in the product container.
  • expansion body by other measures, for example by heating or foaming or - when using a hollow expansion body - by inflating with a liquid or gaseous medium.
  • Another possibility is to insert the expansion body in the product container without oversize and then by the

  • the spray can shown in FIG. 1 has a product container 1.

  • the outer container 1.2 consists of an elastic material that forms the energy store. The two containers lie with their corresponding ones Surfaces directly next to each other. You keep this contact in any operating condition.
  • the inner container thus follows the movement of the outer container when it expands or contracts.
  • the outer container 1.2 is thickened in its upper region to form a flange 1.2.1.
  • the flange is cylindrical.
  • a pot-like receptacle body 2 can also be seen. This tightly encloses the flange 1.2.1.
  • the receiving body 2 has a cylindrical peripheral wall 2.1, a circular plate 2.2 and a collar 2.3.
  • the receiving body 2 is in turn enclosed by a receiving hollow body 3, namely by its neck 3.1.
  • the receiving body 2 is secured against axial displacement.
  • the flange 1.2.1 of the outer container 1.2 encloses a valve 4.
  • a filling and emptying nozzle 5 is connected to this. Filling material is introduced through the filling and emptying nozzle 5 and through the valve 4 for the purpose of filling, and is also let out again when the spray can is used in the opposite direction.

  • the longitudinal channels 6.1 extend practically over the entire length of the expansion body 6. This creates a conductive connection between the valve 4 and the lower region of the product container 1.
  • the outside diameter of the product container 1 has an oversize compared to the inside width of the product container 1 in the non-assembled state. This means that the product container 1 during assembly - opening - on the Expansion body 6 is expanded and thus encloses it under tension.
  • filling is through the filling and emptying nozzle 5 and further through the valve 4 under pressure in the upper region of the
  • Product container 1 initiated. It then flows down through the channels 6.1 of the expansion body 6. Since the introduction takes place under pressure, the product container 1 is expanded so that it is lifted off the expansion body 6. An annular space is thus created over the entire length of the product container and is filled with product. With this expansion the works
