Definitions

  • the invention relates to a closure cap according to the preamble of patent claim 1.
  • a closure cap of the type mentioned is known. It relates to a foam generating device in which a sealing washer seals a channel when the container is under pressure, while the liquid flows out through a dip tube, a valve housing channel, a section of the valve housing lying above the valve through slots of the valve housing approximately at a right angle in an area between an inner wall of the closure cap and a first half of the valve housing occurs.
  • the air is forced vertically upwards through openings and grooves in the area mentioned, so that it mixes with the liquid of the container after the valve and an overlying channel have opened due to the container pressure.
  • the invention is therefore based on the object of improving a closure cap of the type mentioned so that the ventilation of the container is excluded after the compression of its flexible wall through the dispensing opening, but nevertheless an economical mass production of the closure cap is possible by simple construction of the closure cap.
  • the invention solves this problem by the features contained in the characterizing part of patent claim 1.
  • the arrangement of the outlet valve upstream of the discharge opening, which is only opened when there is excess pressure in the container, reliably prevents the container from being re-ventilated and thus the risk of suction of substances contaminating the container contents through the discharge opening.
  • the maintenance of the quality of the spray material in the container is ensured by the ventilation opening, which is separate from the discharge opening, and the ventilation valve, which only opens when there is negative pressure in the container.
  • connection opening provided between the chamber connecting the riser pipe to the discharge opening and the upper, air-containing part of the container enables the active product to be mixed with the air forced out of the upper part of the container through the connection opening.
  • This mixing effect is naturally achieved in particular when the container contents consist of a liquid, so that the closure cap is particularly suitable for liquids as the active product.
  • closure cap which accordingly consists of only four individual parts, namely the actual closure cap, a riser pipe holder, a single flexible valve component, which at the same time is the valve parts for the outlet valve and for the ventilation valve poses, as well as from the riser.
  • the valve seat of the outlet valve 8 is formed by a cylindrical pin 13 which projects coaxially into the cylindrical chamber 11 from the underside 14 of a head wall 15.
  • the cylindrical pin 13 forms an annular space 16 with the chamber wall 17 of the chamber 11.
  • On the chamber wall 17 a flexible valve part 18 is fastened, which abuts with a circular central hole edge 19 on the peripheral surface of the pin 13.
  • the flexible valve part 18 of the outlet valve 8 extends from the chamber wall 17 to the edge of the hole 19 in the direction of the discharge opening 6 in the form of a round crest 20.
  • the discharge openings 6 are arranged in the top wall 15 of the chamber 11, which extends from a centrally projecting cap dome 21 is formed.
  • a foot 22 of the cap dome 21 is surrounded by an annular shoulder 23 which has the ventilation opening 9 in the foot area.
  • a cap jacket 24 extends from the outer edge of the annular shoulder 23 approximately coaxially to the central longitudinal axis of the closure cap 5 and is shaped so that it can be placed on the container neck with a press fit or snap fit. Alternatively, a screw connection can also be selected.
  • the underside 25 of the annular shoulder 23 forms the valve seat for a flexible valve part 26 of the ventilation valve 10 radially outside the ventilation opening 9.
  • the flexible valve part 26 is fastened to the chamber wall 17 and extends like an annular disk approximately parallel to the annular shoulder 23 and extends radially outwards the ventilation opening 9 and is provided on the outer edge with an upstanding sealing lip 27.
  • valve component 28 is preferably made of very soft polyethylene, rubber or silicone.
  • the valve component 28 consists of a cylindrical section 29 which extends along the chamber wall 17 and connects the upper round crest 20 of the outlet valve 8 to the annular disk-shaped valve part 26 of the ventilation valve 10. This enables the closure cap to be produced from a few individual parts with very simple assembly.
  • a cylindrical riser pipe holder 30 is inserted into the lower opening 31 of the chamber 11 and press-fits the two flexible valve parts 18 and 26 of the outlet valve 8 and the ventilation valve 10 formed by the one-piece valve component 28 on the chamber wall 17.
  • the riser pipe holder 34 is expanded at 32 compared to the diameter of the riser pipe 7 provided at its lower end. In this extension area 32, two diametrically opposite connection openings 12 are provided. When the container is pressed together, these connecting openings allow air to escape from the container into the chamber 11 and to mix with the spray material in the chamber before it is sprayed out of the discharge openings 6. It is understood that there may be only one or more than two connection openings.
  • the ventilation valve 10 is kept tightly closed by the overpressure that arises in the container, while on the other hand the overpressure counteracts the liquid container contents, for example, through the riser pipe 7 and the chamber 11 presses the hole edge 19 of the flexible valve part 18, which is lifted off the cylindrical peripheral surface of the pin 13, so that the liquid can flow out through the two dispensing openings 6 adjacent to the pin 13 in parallel.
  • the liquid flows out as a spray mist because air contained in the upper part of the container has been mixed with the spray liquid through the connection opening 12 in the chamber 11.
  • the outlet valve 8 closes when pressure is exited.
  • the container wall then moves due to its resilience back to their original position.
  • the valve part 26 is lifted from the ventilation opening 9 due to the low pressure in the container relative to the atmospheric pressure, so that the part of the container which is free of liquid is filled with air until pressure equalization. As soon as the pressure equalization is reached, the elastic valve part 26 of the ventilation valve 10 closes automatically.
  • a ventilation valve 37 is designed differently in this second embodiment.
  • a cylindrical sealing collar 33 protrudes from the underside 25 of the annular shoulder 23 coaxially to the chamber 11 and surrounds the ventilation opening 9.
  • the inner wall 34 of the sealing collar 29 forms the valve seat for the outer edge 35 of a flexible valve part 36 of the ventilation valve 37.
  • a riser pipe holder 34 is formed essentially as that in Fig. 1, but also has in the transition area 32 to the riser 7 outside an annular flange 38.
  • the radius of this annular flange 38 is smaller than the radial distance of the ventilation opening 9 from the central longitudinal axis of the cap 5.
  • the annular flange 38 is arranged at an axial distance from the underside 25 of the annular shoulder 23 such that the flexible valve part 36 of the ventilation valve 37 extends downward and outward against the inner wall 30 over the annular flange 38 through an annular gap 39 between the annular flange and the sealing collar 33 and lies tight against it in the closed position.
  • this embodiment has the advantage that the ventilation valve 37 reacts more sensitively or faster than in the case of the first embodiment. It is also more favorable in terms of flow.
  • the shape of the one-piece valve component 40 in FIG. 2 also enables easier manufacture in the injection molding process, since the diameter changes are flowing from the valve part 36 via the cylindrical section 29 to the upper hole edge 19.
  • the closure cap itself is preferably made of polyethylene, polypropylene or other thermoplastic materials.
  • the closure cap can be placed on a suitably designed container neck by means of a snap fit or a press fit, or it can be screwed onto a threaded container neck by means of a screw closure.
  • the riser pipe holder and the riser pipe can also be made from appropriate materials.
  • the riser pipe holder 30, on which the riser pipe 7 is mounted, and the flexible one-piece valve component 28 or 40 are held in the chamber 11 of the cap dome 21 of the closure cap by a press fit.
  • the active spray material preferably liquid
  • the active spray material is guided through the riser pipe 7 and the riser pipe holder 30 into the chamber 11 by pressure on the container.
  • air that is located above the active product inside the container also passes through the connection opening 9 of the riser pipe holder 30 into the chamber 11, where it mixes with the active product.
