Definitions

  • the invention relates to a drip cap for dosing out liquid in drop form from a container whose contents are to be dosed out is pressurizable, with a cap body in which a Outlet channel and a throttle device is arranged, in Flow direction before the inlet opening of the outlet channel fixed is arranged.
  • the invention also relates to a container A drip cap according to claims 9 and 10.
  • Drugs that are used in liquid form are used in Tubes or vials provided from which they are in drop form be dosed. Since the medication is linked to the number of drops It is crucial that the drop volume during Dosing is always constant and not by the user can be influenced.
  • the drip insert has, in addition to the outlet channel, an air channel, through the air during dosing into the vial interior can.
  • Drop cap only one outlet channel, through which the liquid through Pressure is dosed on the container wall. This is what matters on that the outlet channel exactly defines the drop size.
  • Such a dropper tip for eye drops for example, in the EP 0 431 885 A1.
  • the outlet channel has a Inlet opening whose cross-section is smaller than that of the Outlet opening, wherein substantially the size of the outlet opening the drop size determines.
  • EP 0 956 904 A1 describes a dropper insert which is inserted in a Container can be used. This dropper should be independent always provide constant drop sizes from the pressure on the liquid. Starting from an outlet channel with an inlet opening, the smaller than the outlet opening, are next to conical Outlet channels including those with cylindrical sections proposed.
  • EP 0 956 904 A1 states that the drop shape is independent of the pressure exerted on the liquid pointed out that this does not always succeed. It has been shown that especially at higher pressures in connection with the production larger drops from a certain pressure value Outlet jet forms or the drops an uncontrolled shape and thus assume an undefined volume. The dosing safety is not guaranteed.
  • Throttle device opens depends essentially on the elastic Properties of the container material from, so that at different Materials also different pressures have to be applied, each time the operator has to readjust. It is therefore desirable that a metering with constant Drop size is made possible by the chosen container material is independent.
  • DE-AS 10 63 755 describes a plastic dropper bottle, especially for drugs whose drip opening is a dazzling Insert is upstream, which is a hole with a small diameter having.
  • the liquid to be dosed enters directly into the Outlet channel, wherein in particular at high pressures a Beam can form, which continues in the outlet channel and there a targeted dosage and dripping prevents.
  • the task is with a drip cap for dosing Liquids dissolved in the form of drops, in which the throttle device spaced apart from the inlet opening, and at between the inlet opening and the throttle device an intermediate chamber is arranged, by the bottom wall of the cap body and a Chamber wall is limited.
  • Throttling device can be the maximum pressure on the liquid to be dispensed acts before or in the outlet channel, be set.
  • the throttle device also ensures at high pressure exerted on the liquid, that in the outlet channel always constant pressure conditions are maintained.
  • the liquid through the throttle device with high flow velocity
  • the liquid could pass directly into the jet as a jet Penetrate the inlet opening, wherein the jet in the outlet channel which prevents the formation of constant droplet sizes could.
  • the intermediate chamber has the advantage of being First, you can collect the liquid here before putting it in the Ingress opening of the outlet channel penetrates.
  • the volume of the intermediate chamber is greater than or equal to Volume of the outlet channel. This will ensure that that entire volume necessary for a drop in the Intermediate chamber is provided under suitable pressure.
  • the intermediate chamber of the cap body and limited to a chamber wall.
  • the throttle device is preferably in the chamber wall arranged.
  • the throttle device may have at least one passage opening in the Chamber wall, whose cross-section is smaller than that Cross section of the inlet opening of the outlet channel.
  • Other Throttling devices such as valve flaps or the like can also be used.
  • the passage opening may be opposite to the inlet opening. It is but advantageous if the passage opening offset from the Inlet opening is arranged, because thereby by the Passage opening formed liquid jet first a diversion and thus undergoes a further pressure reduction.
  • the chamber wall preferably consists of an annular wall and a Partition wall.
  • the ring wall can be adapted to the dimensions of the Be adapted cap body.
  • the throttle device is preferably arranged in the partition wall.
  • the chamber wall is integrally formed on the cap body.
  • the drip cap and container can be combined in different ways become.
  • the drip cap according to the invention can be an integral part of the Be container.
  • a first Variant is the drop cap according to the invention as an insert for Made available in the container neck any conventional Container is used.
  • a conventional drip cap with outlet channel wherein the Drip cap has a bottom wall with an inlet for the Has outlet channel.
  • the throttle device is in this embodiment arranged in a partition of the container, said partition spaced apart from the bottom wall in the interior of the container is and where between the partition and the bottom wall a Intermediate chamber is located.
  • the partition wall is preferably arranged in the container neck.
  • the partition is perpendicular to the container axis arranged.
  • the partition can be used in the container or be an integral part of the container.
  • the throttle device is preferably in this partition arranged.
  • the throttle device comprises at least one passage opening in the partition whose cross section is smaller than the cross section of Inlet opening of the outlet channel.
  • This opening can be the maximum pressure on the outlet channel acts, be adjusted. It ensures that the to be dispensed liquid under the same pressure in the Outlet channel occurs, so that no influence on the of User applied pressure on the drop shape can take place.
  • the passage opening is preferably located at the inlet opening across from. In this case it is important that the distance between the throttle opening and the inlet opening is as large as possible, so that the incoming liquid is not directly into the outlet channel which in turn leads to a radiation hazard at the end of the Outlet opening of the outlet channel could result.
  • the passage opening preferably offset from the inlet opening arranged.
  • the volume of the space between the Drip cap and the partition greater than or equal to the volume of Outlet channel.
  • the conventional or inventive Container a flexible container wall, for example made of plastic can exist.
  • the container can be a tube, a vial or a be another suitable container.
  • Through the flexible container wall is it is possible, for example, by hand, the contents of the container below To put pressure and so make the dosing.
  • a printing device on or in the container be provided or the container may be to a printing device be connectable.
  • a printing device would be e.g. one Pumping mechanism with the example air into the container interior is pressed, so that thereby the liquid through the Throttle device is pressed.
  • the drip cap can be liquid or pressure tight in the container neck be usable. There is a possibility, for example, by Welding the drip cap a tight connection with the container manufacture.
