Definitions

  • the invention relates to a cap for containers, in particular in the blow molding process made of plastic and filled and closed in the mold, which has the features of the preamble of claim 1.
  • the thread pierced with the mandrel can occur Opening runs obliquely with respect to the longitudinal axis, or that after removal of a partial quantity and subsequent screwing on of the cap, a second opening is pierced, with the result that the liquid may escape at several points in a direction deviating from the longitudinal axis, which is annoying , it depends on the pressure exerted on the liquid whether the liquid is released in more or less large drops or in the form of a jet.
  • the size of the opening can change in the course of time if, after a portion of the bottle content has been removed, the neck is closed again with the cap and the mandrel is then reinserted into the opening. It is therefore difficult to dose the correct amount correctly.
  • a known cap of the type mentioned covers a dropper insert which engages with an annular, hollow cylindrical collar in the neck of the bottle.
  • the passage channel of which consists of a tapering conically in the outflow direction, a cylindrical second adjoining it Section, the diameter of which is approximately equal to its axial length and substantially smaller than that of the first section, a third section which widens conically in the outflow direction and a cylindrical fourth section adjoining the latter.
  • a transition section forming an end face adjoins the section receiving the neck, with which a spray nozzle is formed in one piece.
  • This cap defines a dosing device inserted into the bottle with a ball valve, which makes it possible to dispense the contents of the bottle in the form of a dosed jet.
  • the invention has for its object to enable easy removal of the liquid content of bottles in the form of individual drops of a defined size. This object is achieved by a cap having the features of claim 1.
  • the portion of the cap according to the invention designed as a dropper the dispensing of the liquid content of the bottle is not carried out by means of an opening formed by the bottle neck, but by means of the dropper of the cap.
  • This dropper can easily be designed so that it forms drops of reproducible size regardless of the prevailing pressure and then reliably excludes the discharge in the form of a jet.
  • the cap according to the invention can be used for bottles, for example ampoules, which have a closure part which is initially to be provided with a passage opening, an end face is provided at the transition of the cap from the portion receiving the neck to the portion designed as a dropper, against which a Bottle protruding mandrel is formed, in which the passage channel of the dropper begins.
  • the closure part can then be pierced by means of the mandrel as in the known caps with mandrel. Since the dropper is dosed, it is irrelevant in this case whether the opening in the closure part is formed exactly in the center and coaxially and whether its size deviates from the nominal value.
  • the passage channel of the dropper has at least two end sections opening into the lateral surface of the mandrel, which end portions lie within the bottle neck when the cap is completely placed on the neck.
  • a very good reproducibility of the droplet size and a reliable prevention of a jet-like delivery of the bottle contents can be achieved with a passage channel of the dropper which, following a cylindrical section, has a section which widens conically in the outflow direction. These sections are preferably calibrated during manufacture by means of a calibration mandrel.
  • the cap it is also possible to design the cap so that it can be arranged on the neck with the formation of a sliding seat. As a rule, however, the portion of the cap receiving the neck will be provided with an internal thread which is designed to correspond to an external thread of the neck.
  • a closure part is provided so that it can be removed from the section designed as a dropper, so that the passage channel of the dropper is protected.
  • This closure part is preferably designed as a cup-shaped hood with an internal thread which corresponds to an external thread of the section designed as a dropper.
  • a spigot can be formed centrally on the inner surface of the bottom of this hood, which can be inserted in a sealing manner into the passage channel of the dropper.
  • the invention is based on one in the drawing illustrated embodiment explained in detail.
  • the only embodiment shows, on an enlarged scale and partly in longitudinal section, the embodiment in the state placed on the neck of a bottle before the closure part of the neck is pierced.
  • a plastic cap designated as a whole as 1 has, as the figure shows, a first, hollow cylindrical section 2, which serves to accommodate the neck 3 of a bottle which, in the exemplary embodiment, was made from plastic in the blow molding process and was filled and closed in the blow mold is, the plate-shaped closure part 4 closing the neck 3 being formed in one piece with the neck 3.
  • the neck 3 of the bottle which can be an ampoule, is provided with an external thread 5.
  • the neck 3 has a cylindrical section 6, the external diameter of which is selected to be equal to that of the external thread 5.
  • annular bead 7 projecting slightly beyond this section. The diameter of this annular bead 7 is slightly larger than the inner diameter of the zone forming the free end of section 2.
  • the section 2 is provided with an internal thread which corresponds to the external thread 5 of the neck 3, but does not extend into the zone forming the free end section.
  • the section 2 is adjoined on the side facing away from the bottle body 3 ', coaxially and in one piece, by a section designed as a dropper 8, which is provided with an external thread 9 and whose free end is rounded off in a hemispherical manner.
  • a conical mandrel 10 is formed in the center of the inner end face 8 ′ of the dropper 8 present at the transition from the section 2 to the dropper 8, the tip of which points into the interior of the section 2.
  • the design of the passage channel and in particular its two sections 12 and 13 can also be chosen differently, since it depends on the properties of the liquid, for example its viscosity and surface tension, as well as on the drop size and whether it is delivered in drop form or in the form of a Beam is desired.
  • a cup-shaped protective hood 14 is provided which, like the cap 1, is made of plastic.
  • the protective hood 14 is provided with an internal thread corresponding to the external thread of the dropper 8 and extends almost up to the outer shoulder of the cap 1 formed at the transition from the section 2 to the dropper 8.
  • the protective hood 14 is in the center of the bottom the inside of which a pin 15 is integrally formed, which engages in the conical section 13 and closes it tightly when the protective hood 14 is screwed completely onto the dropper 8.
  • the cap 1 is screwed onto the neck 3 so far that the free end of the section 2 extends up to the annular bead 7 of the neck 3, as the figure shows. This position can be easily recognized from the fact that when the cap 1 is screwed even further onto the neck 3, the section 2 comes into contact with the annular bead 7 and thus an increased torque is applied must become.
  • the cap 1 is screwed onto the neck 3 up to the annular bead 7, the mandrel 10 is in contact or almost in contact with the closure part 4.
  • the cap 1 is completely on the neck 3 screwed on.
  • the protective hood 14 needs to be unscrewed in order to remove the contents of the bottle in the form of individual drops of a defined, reproducible size or, if the through-channel for dispensing liquid in Shape of a beam of a defined size is formed, can be removed in the form of a beam.
