Definitions

  • the invention relates to a discharge head for a tube for discharging medium from the tube with a flat outer housing with a receiving shaft for inserting and securing an outlet of the tube on the rear facing the tube and an outlet opening for discharging the medium on an opposite end face, with an interior space surrounded by walls of the outer housing, an annular wall section of the outer housing separating the receiving shaft from an annular region of the interior of the outer housing surrounding the annular wall section on the outside, with an outlet valve provided in the interior with a valve body and a valve seat and with a pressure chamber designed in such a way that pressurization of the medium contained therein, the valve body and the valve seat from a closed position to an opening position can be spaced from each other to a leakage of the medium from the pressure chamber through to allow the discharge opening, and with a medium path inside the housing, through which an inlet opening on the receiving shaft is connected to the pressure chamber.
  • the invention further relates to a tube with a discharge head, wherein the tube has an outlet with a reduced
  • Tubes and very simple discharge heads for this purpose are generally known in particular for receiving and delivering toothpaste.
  • the tubes used for this purpose have a usually provided with an external thread outlet, which has a substantially reduced diameter compared to the outer diameter of the tube.
  • the discharge head is therefore usually screwed on toothpaste tubes on this outlet.
  • pivotable protective cap is provided, which is locked when not in use in a the outlet opening of the discharge head closing position.
  • a discharge head for tubes is also known in which a pressure-controlled outlet valve is provided which automatically opens when the medium in the tube is pressurized and automatically closes when this pressurization ceases.
  • a protection against contamination of the medium can be achieved, which allows to use a tube with such a discharge head for receiving and dispensing preservative-free media.
  • the object of the invention is to develop a generic discharge head for a tube such that the disadvantages of the prior art are overcome.
  • this is achieved by a generic discharge head in which the medium path extends from the inlet opening through the annular region of the interior of the outer housing to the pressure chamber, so that the medium on the way from the inlet opening to the pressure chamber in sections in one direction flows, which has at least one directional component, which is directed against a plug-in direction of the outlet in the receiving recess.
  • the discharge head according to the invention has on opposite sides, on the one hand, the receiving shaft for the outlet of the tube and on the other the discharge opening.
  • the already mentioned insertion direction of the tube is defined.
  • This insertion direction refers to the positional displacement of the tube relative to the discharge head in the course of attachment of the tube.
  • the rotational position of the tube does not play for this Roller, so that even with a fastening of the tube by means of a thread, the insertion direction by definition runs in the direction of the threaded axis.
  • the outlet opening of the discharge head is provided on the opposite side of the rear side of the tube head and preferably such that it is suitable for a Med iu maustrag in the direction of insertion.
  • the attachment of the outlet nozzle of the tube takes place in the receiving shaft of the discharge head preferably via a form-fitting clamping connection, in which on the inside of the receiving shaft and on the outside of the outlet nozzle of the tube corresponding profilings are provided.
  • the aforementioned design with a thread is considered advantageous.
  • the core of the first aspect of the invention is that the medium path, which connects the at least one inlet opening with the pressure chamber and thus also the outlet opening, extends at least in sections through that annular area of the interior, which is bounded on the inside by the annular wall section of the receiving shaft. Consequently, the medium path is such that the medium flowing into the discharge head at the inlet opening is deflected and thus flows in phases opposite to the insertion direction or flows in a direction which has at least one direction component opposite to the insertion direction.
  • the Ringwandungsabterrorism the receiving shaft must not necessarily come into contact with the medium. Instead, external walls of the annular wall section can also be provided which delimit the flow path of the medium.
  • the construction mentioned leads to a considerable gain in space.
  • the medium Since the medium is deflected in the annular space surrounding the receiving shaft, it can be conveyed from here to the outside and then in the insertion direction to reach the pressure chamber. As a result, a large proportion of the interior of the outer housing for the medium path is not required, so that this space can be used elsewhere, in particular for receiving relevant parts of the exhaust valve. This makes it possible to design the discharge head in the desired flat design and still have sufficient space to accommodate the exhaust valve available.
  • the second aspect of the invention which is preferably implemented together with the first aspect of the invention, provides that the pressure chamber extends between an inner side of an end wall of the outer housing and a in the interior of the outer housing substantially parallel thereto arranged counter surface and that the medium path extends outwardly from the inlet opening with respect to the insertion direction of the outlet nozzle into the receiving recess, so that the medium coming from the inlet opening can flow into the pressure chamber only in an outer edge region.
  • the medium does not flow axially and without significant change of direction from the inlet opening of the discharge head to the outlet opening, but is conveyed radially outwards from the inlet opening in such a way that it can flow in from outside into the pressure chamber on the counter surface.
  • the discharge head for applying force to the valve body in the direction of the valve seat has a spring, said spring being at least partially disposed in the annular space of the interior.
  • the space is used for this spring, which surrounds the receiving shaft of the discharge head. Since thus comparatively long spring lengths can be realized, the adjustment of the opening behavior of the exhaust valve is particularly well and precisely possible.
  • the spring is designed as a helical spring and surrounds the receiving shaft at least in sections.
  • the annular walls of the receiving shaft or corresponding annular walls of an inner housing to be explained below can also be used to achieve a positional fixing of the spring transversely to the insertion direction.
  • an inner housing is arranged within the interior of the outer housing, the media path extending between outer walls of the inner housing and inner walls of the outer housing, and furthermore an inner space of the inner housing being sealed in a liquid-tight manner with respect to the medium path.
  • This inner housing fulfills several purposes. On the one hand, it can accommodate in its interior functional elements of the exhaust valve, which are protected by a liquid-tight construction of the inner housing from the environment. On the other hand, it can define the one or more media paths from the inlet opening to the pressure chamber with its outer contour and in interaction with the inside of the walls of the outer housing. By adapted to the inner contour of the outer housing shaping can be prevented that arise too large dead volumes in the media path, ie spaces in which remains medium and from which this medium after emptying the tube is no longer to remove.
  • the inner housing has a recess into which projects the annular wall of the outer housing. This depression makes it possible to maximize the internal volume of the inner housing.
  • the recess into which the annular wall portion of the outer housing is inserted can be used in the manner already mentioned above for supporting a valve coil spring.
  • the inner housing forms a pressure chamber delimiting counter surface on which the valve body is provided.
  • the mating surface is at least partially movable relative to a base section of the inner housing provided stationary with respect to the outer housing. This can be achieved in that the mating surface is guided displaceably on the base portion of the inner housing.
  • the mating surface consists of two different materials of different deformability. This makes it possible to firmly and connect the counter surface with the base portion and still achieve a mobility of the valve body.
  • an annular portion made of a material of higher deformability between an outer outer ring and the valve body of the counter surface is arranged, which are formed of a material of lower deformability.
  • the medium path is formed at least in sections by channels which are formed by recesses in the outer housing and / or in the inner housing and which are circumferentially closed by the other housing, said latter Channels preferably in the region of their confluence with the pressure chamber have an increase in their free cross-section.
  • the enlargement of this cross section allows the dead volumes low and yet to ensure that the medium flows into the pressure chamber over the entire circumference or at least over almost the entire circumference (> 50%). The formation of air bubbles is thereby effectively prevented.
  • the invention further relates to a tube with a erfindunswashen discharge head.
  • the tube has an outlet with reduced compared to a maximum tube diameter outside diameter. This outlet is inserted inserted in the insertion in the receiving shaft of the discharge head.

  • the media supply into the pressure chamber 70 from the outside ensures that reliably any air is discharged from the pressure chamber 70 through the discharge opening 44a. It is therefore not to be feared at the beginning of a discharge process that air pockets remain in the pressure chamber 70, which are compressed in the course of pressurization and expand abruptly and unexpectedly again when the exhaust valve opens.
  • the arrangement of the media path in said annulus 49 also allows the inner housing 50 to occupy most of the interior space 48 of the outer housing 40. Thus, in particular, there is enough room to arrange the spring 58 here.
