Definitions

  • the invention relates to a dosing for placing on a dosing with a extending in a longitudinal direction dosing with end-side outlet for a liquid to be dosed.
  • Such a dosing is for example from the DE 41 17 220 C1 refer to.
  • Dosing bottles for dosing liquids of different viscosities are used in a wide variety of areas, such as in hygiene articles, in the food sector or in the medical-pharmaceutical sector. Sometimes the most accurate possible, even dropwise metering or even the most dense closing is desired.
  • caps are used, which are usually formed from a base body, which has an outlet opening, for example, for a personal care product.
  • the main body can be closed by means of a lid, for which purpose a closure sleeve or a closure pin is regularly introduced into the outlet opening.
  • the entire cap is often designed as a one-piece plastic injection molded part, in which therefore the lid during injection molding, for example is integrally formed on the base body via a film hinge.
  • the lid can also be designed as a separate part, for example as a screw cap.
  • Such caps are often formed as so-called bounce seals, which are aufprellt on a corresponding bottleneck.
  • the outlet opening is regularly formed by a cylindrical outlet, which usually has a diameter of, for example, three or more millimeters.
  • a conical extension which usually has a comparatively large cone angle of for example 45 °.
  • the object of the invention is to provide a dosing cap which is inexpensive to produce, by means of which dropwise dosing is also possible.
  • the dosing cap serves for placing on a dosing bottle and has a dosing channel extending in the longitudinal direction as far as an end-side outlet opening.
  • the metering channel has a first and a second metering section, which adjoin one another in the longitudinal direction.
  • the first metering section is reduced to a metering diameter which is in the range of 0.2 mm to 1.2 mm.
  • the metering diameter forms the smallest diameter of the entire metering channel.
  • the second metering section connects to the first metering section to form a step.
  • the choice of the small metering diameter basically allows the possibility of only dropwise metering. Of particular importance is the adjoining the metering diameter second metering with the enlarged Diameter. By this namely, an unwanted escape of liquid residues from the outlet opening, for example. After a dosing avoided, even if the metering bottle provided with such a dosing is stored upside down. Essential for this is in addition to the small dosing diameter and the widespread second dosing. Investigations have shown that any drops unintentionally emerging from the first metering section through the metering opening are collected and retained in the second metering section.
  • the step-like transition defines a tool parting plane between two punches forming the two metering sections.
  • This embodiment is based on the consideration that for a simple cost-effective production of the dosing with the dosing an injection molding process is suitable.
  • metering orifices can only be realized by means of corresponding punches in the injection molding tool.
  • these punches usually have a minimum diameter of 1.5 mm, which is too large for the desired metering opening.
  • first metering section In order to enable the fine structure of the first metering section is provided for producing the metering cap in the context of an injection molding process, that tooling initially for the formation of the metering further initially first punch with sufficient diameter is used for the second metering section.
  • first punch In addition, to form the first metering section with the end-side metering opening with the small metering diameter, a second punch with only a small diameter is used, which defines the diameter of the metering opening.
  • the second stamp which has only a low stability, is supported on the first stamp. The two punches are therefore introduced from opposite sides and define a dividing plane between them.
  • the metering can be formed with a sufficiently small metering diameter. Overall, this creates a possibility to produce a dosing cost, which also reflected in the special design of the dosing.
  • a Dosierkappe is provided with the embodiment described here, with which without problems even in aqueous liquids, a dropwise dosage or - when using elastic, squeeze ble bottles - when pressure on the bottle and a Dosierstrahl set.
  • the entire dosing is formed as a one-piece plastic injection molded part. It is therefore not necessary to connect several parts.
  • the metering diameter is in a range between 0.2 and 1.2 mm, in particular it is limited to a maximum of 0.8 mm. The choice of the specific metering diameter depends on the field of application, in particular of the liquid to be metered.
  • the dosing diameter is limited to a maximum of 0.4 mm and in particular to 0.25 mm. With these small metering diameters, a passage of the liquid is reliably avoided. In terms of manufacturing technology, however, such small diameters are very sensitive, since correspondingly required punches are very fine. In order to ensure reliable production, it is therefore provided, in particular with these small metering diameters, that the first metering section tapers, starting from a first inlet diameter, in particular conically under a cone angle, the first entry diameter being at least 1.4 mm and preferably at least 1.8 mm. The ratio of the first inlet diameter to the metering diameter is preferably above 5, in particular above 8.
  • the cone angle is preferably above the value for typical Entformungsschrägen and is in particular above 8 ° and for example in the range of 10-15 °. In this way, a frusto-conical first metering section is created, which has at its base a sufficient width, which corresponds to a sufficiently stable punch width. Overall, the dosing is formed elongated.
  • the first metering section has at its end a first cylindrical intermediate section. Due to the elongated, conical region of the first metering section, which tapers to the metering diameter, a strong slowing down of the flow of the liquid is initially achieved. Investigations have now shown that the adjoining cylindrical intermediate section, which thus has only the metering diameter, has a favorable effect on an unwanted escape of liquid.
  • this cylindrical intermediate section defines a first collecting space for the liquid in order to prevent it from emerging from the outlet opening at the end.
  • the length of the cylindrical intermediate portion is preferably approximately in the range of Dosier micmessers.
  • the second dosing section has, in an expedient embodiment, an intermediate region with a reduced diameter.
  • This intermediate region is formed in particular in the manner of a constriction, in the region of the intermediate region is therefore, for example, a circumferential web formed, so that the second metering is constricted in total ringnutartig.
  • this Constriction reduces the diameter of the second Dosierabitess for example. By 10% to 20%.
  • a second, in particular cylindrical, intermediate section adjoins the intermediate region with a reduced diameter.
  • the intermediate region and the intermediate section of the second metering section are in this case formed on the end, in particular in the last quarter of the second metering section.
  • the intermediate area has a reduced diameter of max. 1.0 mm to 1.5 mm in particular of about 1.2 mm. However, the reduced diameter is above the metering diameter.
  • the second metering section itself is preferably likewise conical, like the first metering section, with the difference that it widens conically in the longitudinal direction, that is to say in the direction of the outlet opening.
  • Both the first and the second metering section are therefore preferably formed approximately in the shape of a truncated cone. They have a cone angle, which lies in the range between 1.5 ° to 5 °.
  • the term "cone angle” is understood to mean the angle at which-as viewed in a longitudinal section-a respective boundary of the respective metering section is inclined in relation to a central longitudinal axis and thus in relation to the longitudinal direction.
  • At least one, in particular the first metering section and preferably both metering sections are formed elongated. So they have a length which is a multiple, in particular more than three or four times the respective minimum diameter of the respective metering section. As a result, a comparatively large path length is created overall, which reliably prevents in particular unwanted leakage of liquid.
  • the outlet opening itself has an exit diameter, which is usually greater than or equal to 1.5 mm and in particular in the range of 1.5 mm to 2.5 mm.
  • the outlet opening is part of an outlet section of the metering channel, wherein the outlet section in turn has a larger diameter than the second metering section.
  • the outlet section adjoins the second dosing section to form a second step.
  • a respective section of the metering channel has a larger diameter than a preceding section, this means that an enlarged diameter is present in the transition region between the two sections.
  • the largest diameter, for example, of the first metering section is larger than the smallest diameter of the second metering section.
  • the dosing cap comprises a bottle neck collar designed in the manner of an apron, which surrounds an interior space.
  • a dosing which has the metering channel extends.
  • the metering pin is part of a metering element, which extends in total through a frontal lid base, so that the metering outside of the outside of the lid bottom forms a metering tip in the manner of a dome-like elevation.
  • the bottle neck collar is an inner apron which is usually additionally surrounded by an outer bottle neck collar and this in turn is surrounded by an outer wall.
  • the bottleneck collar is designed as an annular collar. About this is insofar also a dosing anteroom formed for the liquid to be dosed. If the dosing cap is placed on the dosing bottle, the bottleneck collar usually engages precisely in a bottleneck of the dosing bottle, so it is preferably in a flush and sealing manner against a cylindrical (inner) surface of the bottle neck. This ensures that the liquid to be dispensed exits exclusively via the metering opening.
  • the collar in this case preferably has a conical sealing slope on the end side.
  • the collar extends longitudinally over, for example, 8 mm to 20 mm, and typically over about 10 mm to 15 mm.
  • the dosing cap is formed in a preferred development as a bounce cap.
  • the dosing cap is therefore placed by simply bouncing on the neck of the bottle.
  • a screwing etc. is not required.
  • the principle of the embodiment described here for the dosing element can in principle also be transferred to screw closures of any type.
  • the dosing cap additionally has a closure lid, which sealingly seals the outlet opening in the closed state. This additionally ensures that, for example, during transport or even with a tilting of the dosing no liquid escapes from the bottle.
  • Dosing cap 2 shown comprises a base body 4 and a closure lid 6, which forms a common, monolithic injection molded part together with the base body 4.
  • the closure lid 6 is connected via a film hinge 8 pivotally connected to the base body 4.
  • the dosing cap 2 is further formed in the embodiment as a bounce cap, which is attached by a simple bouncing on a bottleneck on a dosing bottle not shown here.
  • the metering bottle is, for example, an elastic plastic metering bottle, which is provided, for example, for holding liquid foods, liquid hygiene articles, liquid pharmaceutical products or medicaments. About the dosing 2 while dosing the liquid contained in the bottle is possible. Liquid is understood to mean both an aqueous and a viscous mass.
  • the base body 4 has to be placed on the bottleneck of the dosing an inner annularphasenhalskragen 10 and an outer annularphasenhalskragen 12, between which in the mounted state of the bottle neck of the dosing is absorbed as possible sealing.
  • the main body 4 still has a peripheral outer jacket 14. This goes on the front side in a substantially horizontally extending forehead bottom 16.
