Definitions

  • the invention relates to a valve for a squeeze container, from which a liquid or creamy substance can be squeezed out by reducing the interior of the squeeze container when its flexible walls are pressed in and air can penetrate into the interior when the walls of the squeeze container are reset.
  • Such squeeze containers are used in particular as plastic bottles with flexible walls for numerous applications. They are suitable for dispensing pasty substances such as toothpaste viscous substances such as body milk and shower products / as well as for low-viscosity substances such as washing-up liquid, petrol or the like.
  • Such squeeze bottles are regularly provided with an insert inserted into their bottle neck, the cross section of which is adapted to the outlet opening of the usually desired dosage of the substance in question.
  • the squeeze bottles usually in use have the disadvantage that substance can escape from them if the squeeze bottle is not standing upright, but is lying or even turned upside down. For heavily liquid substances, it is advisable to empty the bottle completely before using it, so that the substance is in the bottle before use Area of the bottle neck flows.
  • an upright position of the bottle can often not be avoided, for example when accommodating in a travel or sports bag.
  • the substance can run out if the lid does not close completely, for example because it has not been carefully brought into its complete closed position. This can result in serious inconveniences.
  • valve into the outlet opening of such a squeeze container, which valve only opens when a certain pressure of the substance contained in the container acts on the valve, which is created by the walls being compressed. If the container simply falls over or is brought to a position with the outlet opening pointing downwards, the valve remains closed.
  • a further valve must be provided that allows air to penetrate into the interior of the container so that the flexible walls of the squeeze container can be reset.
  • the air openings must be closed if the substance could flow out, for example, due to an unfavorable position of the container.
  • valves in the outlet opening for example in the bottle neck of a squeeze bottle
  • the invention is therefore based on the object of creating a valve of the type mentioned at the outset using simple and inexpensive elements in a cost-effective and space-saving manner.
  • This object is achieved according to the invention in a valve of the type mentioned at the beginning by a valve plate with at least one first through opening for the substance and at least one second through opening for air,
  • an elastic first valve disc which bears on a side of the valve plate facing away from the interior of the squeeze container, with a closure for the at least one first through opening and with recesses which are aligned with the second through openings and
  • a second valve disc lying on the other side of the valve plate with a closure which closes the at least one second through opening when the interior of the squeeze container is reduced, and a recess which is aligned with the at least one first through opening.
  • the valve according to the invention has three simple parts with which the desired functions can be reliably achieved.
  • the two valve disks one of which exits the substance and the other controls the air inlet, cooperate with a common valve plate and are arranged on the two sides of this plate. Since the valve disks - just like the valve plate - only require a small height, the entire arrangement can be constructed in an extremely space-saving manner and, for example, mounted in a bottle neck, the valve hardly requiring more space than a conventional metering insert which does not perform any valve functions.
  • the desired function for the outlet of the substance is achieved in that the first valve disc pointing the closure for the substance bears against the valve plate under prestress and thus closes the passage opening for the substance in this state.
  • the escape of the substance is therefore only possible when the substance on the closure of the first valve disk Pressure is exerted such that the pretension, which is preferably generated by mounting the first valve disk while deforming this valve disk, is overcome by the pressure generated in the interior of the squeeze container.
  • the valve disk controlling the substance outlet is therefore arranged on the outside of the valve plate, while the valve disk controlling the air inlet is positioned on the inside. This has a through opening aligned with the first through opening provided for the substance and, in the idle state, closes the second through openings provided for the air inlet in the valve plate. If a negative pressure is generated in the interior of the squeeze container by the restoring force of the elastic walls, the second valve disk detaches from the valve plate and releases the through openings for the air, while the first valve disk closes the first through opening for the substance.
  • the valve plate has a centrally arranged first through opening and second through openings arranged concentrically around the first through opening. This arrangement makes it possible to design the valve disks in a rotationally symmetrical manner, as a result of which a reliable function is ensured since there are no torques or tilting moments of the valve disks relative to the valve plate which impair the closing effect.
  • the valve disks each have an outer ring, from which elastic webs hold the respective radially inner closure.
  • the closure in the first valve disk can preferably have a spherical closure surface and can be provided for the closure of a central opening of the valve plate.
  • the spherical closure surface can ensure that the valve disk is centered again and again relative to the valve plate, so that the valve disk does not have to be completely fixed.
  • the second closure of the second valve disk expediently has an annular closure surface which surrounds a central recess which is aligned with the first central through opening of the valve plate.
  • the required elastic training can only be achieved by the plastic material of the webs of the valve disks.
  • the length of the webs it is expedient to make the length of the webs as large as possible, which is preferably achieved in that the webs run on a spiral path from the outer ring to the inner closure.
  • the second through openings in the valve plate are designed as ring slot sections.
  • the parts of the valve according to the invention can be made of any sprayable plastic, that is, they can also be made resistant to chemically aggressive substances.
  • FIG. 1 shows a vertical section through the end of a bottle neck of a squeeze bottle with an inserted valve according to the invention
  • Figure 2 is a plan view of the first valve disc in a sectional view generated by the section line A.
  • FIG. 3 shows a view from below of the second valve disk with the valve plate behind it, generated by a sectional view corresponding to section line B in FIG. 1.
  • Figure 1 shows the end of an outlet opening 1 formed by a bottle neck, into which an insert 2 is pressed, which rests with a cylindrical portion 3 on the inner wall of the bottle neck and whose pushing-in movement is limited by a flange-like edge 4.
  • the insert 2 has a dome-like upper part 5 which has a central exit opening 6.
  • a valve arrangement is fastened in the insert 2, which consists of a valve plate 1, a first valve disk 8 fastened above and a second valve disk 9 fastened underneath.
  • the first valve disk 8, the valve plate 7 and the second valve disk 9 are inserted one after the other from below into the insert 2 and there they grip together behind an annular latching bead 10 which covers the outer edge of the second valve disk 9 and the Holds valve plate 7 in contact with an outer annular stop 11 of insert 2.
  • Another annular stop 12 with a smaller diameter is implemented in the top 5 of the insert 2 and holds the outer edge of the first valve disk 8.
  • Figure 2 shows the circular cross section of the bottle neck and thus the insert 2.
  • the first valve disk 8 adjoins the outer edge of the insert 2 and has an outer, closed ring 13, from which three webs 14 extend spirally to a central closure 15.
  • the central closure 15 has spherical segment surfaces which cooperate with a conically narrowing wall for a central first through opening 16 of the valve plate 7.
  • the contour of the closure 15 is selected so that in contact with the valve seat of the first through opening 16 of the valve plate 7, the approaches of the webs 14 on the closure 15 lie higher than the outer ring 13 of the first valve disk 8. With this arrangement, the closure 15 is also a pretension determined by the elasticity of the webs 14 is pressed against the valve seat of the first through opening 16 of the valve plate 7.
  • the valve plate 7 has three circular slot-shaped second through openings 17 which are separated from one another by narrow, radially extending webs 18.
  • the second through openings 17 of the valve plate 7 are arranged concentrically with the centrally arranged first through opening 16.
  • the second valve disk 9 arranged on the underside of the valve plate 7 also has, as can be seen in FIG. 3, an outer, closed ring 19, from which webs 20 extend spirally to a second closure 21.
  • the second closure 21 is designed as a ring with a greater thickness than the outer ring 19, so that due to the pressing of the outer ring 19 against the valve plate 7, the closure ring 21 of the second valve disk bears against the valve plate 7 with a certain pretension.
  • the locking ring 21 is dimensioned so that it securely closes the second through openings 17 of the valve plate 7 when it is on the underside of the Valve plate 7 is applied.
  • the locking ring 21 delimits a central through opening 22 in the second valve disk 9, which is aligned with the central first through opening 16 of the valve plate 7.
  • the annular second closure 21 lies against the underside of the valve plate 7 due to the pretension and closes the second through openings 17 of the valve plate 7, so that no substance unintentionally pours out of the interior through the second through openings 17 can.
  • the passage of substance through the second through openings 17 is reliably prevented even when the flexible walls of the squeeze container are pressed in, because the excess pressure which arises in the interior presses the closure 21 even more against the valve plate and thus for the secure closure of these second through openings 17 for the Substance cares.
  • valve arrangement according to the invention is constructed with a few parts which are extremely simple and inexpensive to produce and has only a small space requirement.
  • the valve arrangement is therefore suitable for use in mass articles both on account of the spatial conditions and in terms of its economy.
  • All parts of the valve arrangement according to the invention are designed in such a way that they can be mounted in both possible positions, since they are shaped in the same way on both sides. It is therefore not necessary to pay attention to a special position of the individual parts during assembly.
