Definitions

  • the invention relates to a packaging which consists of a bottle-like container with a round mouth part and a screw cap which fits onto the mouth part, the mouth part having a bead ring, an external screw thread and an annular pouring rim.
  • the lower edge of the closure cap is connected via a plurality of shear webs to an outwardly projecting annular collar which has resiliently formed locking teeth which engage with locking teeth which are arranged on the neck of the container when screwed on.
  • the screwed-on cap can only be removed from the container neck by shearing off the shear webs.
  • the cap is preferably made of a thermoplastic, e.g. Polyethylene, and can be produced in one piece by the injection molding process.
  • the object of the invention is to provide a packaging consisting of a container and a closure cap, the closure of which is structurally simplified and prevents manipulation.
  • An essential feature of the packaging material according to the invention is the design of the vessel mouth part, which has an externally arranged screw thread, a bead ring arranged below the screw thread and an annular pouring rim arranged above the screw thread.
  • the screw thread is single-thread to four-thread, preferably single-thread; the pitch of the thread is 2.5 to 6.0 mm, preferably 3.0 to 5.0 mm.
  • the screw thread is preferably designed as a saw thread or as a trapezoidal thread.
  • the bead ring is flared downwards, the angle of inclination being 135 to 150, preferably 140 to 145 degrees.
  • the pouring rim is tapered downwards, the angle of inclination being 130 to 145, preferably 135 to 140 degrees.
  • the angle of inclination is the angle between the outer edge of the conical part and the vertical axis of the mouth part.
  • Another essential feature of the packaging according to the invention is the design, the screw cap, which can be screwed to the mouth part.
  • the lower edge of this cap is designed as a bell-shaped extension, which extends over the bead ring of the mouth part.
  • This design of the cap ensures easy handling of the packaging material without the risk of destroying the double ring described below.
  • a base ring consisting of segments is arranged in the upper part, which preferably has 6 to 50 segments, and there is an undercut in the lower part.
  • a ring (retaining ring) is held between the base ring and the undercut, which is connected to another ring (locking ring) via elastic webs; the latter has a V-shaped profile and is preferably arranged in the same plane as the first-mentioned retaining ring.
  • the number of elastic webs is expediently 3 to 24, preferably 6 to 12.
  • a seal is arranged in the upper part of the screw cap, which closes the mouth part of the bottle-like vessel when it is screwed on.
  • the seal is preferably designed as a flat seal, cone seal or cup seal; it can also be designed in the form of a metering device or a measuring device.
  • the bottle-like vessel preferably consists of glass, in particular a glass with medium hydrolytic resistance (glass type III according to the European Pharmacopoeia Volume II, 1975).
  • the bottle-like vessel conveniently has a volume of 5 ml to 10 1, preferably 100 ml to 2.5 1, the mouth portion of the vessel has an inner diameter of 10 to 70 mm, preferably 18 to 2 8 mm.
  • the outer diameter of the mouth part is 15 to 80 mm, preferably 32 to 45 mm.
  • a special design of the glass vessel consists in that it is coated with a protective layer made of a transparent plastic, for example polyvinyl chloride. The thickness of the protective layer is in the range of 0.4 to 0.6 mm.
  • the screw cap preferably consists of a thermoplastic, in particular a polyolefin such as polyethylene or polypropylene.
  • the double ring composed of the retaining ring, connecting webs and locking ring is made of the same material.
  • the material of the screw cap and that of the double ring preferably have different colors; the materials preferably also differ in their hardness and elasticity.
  • Figure 1 shows a partially sectioned overall view of the screw cap and Figure 2 shows an overall view of the mouth part of the bottle-like vessel.
  • Figure 3 is a detail from Figure 1, and Figure 4 shows a top view of the isolated double ring.
  • the screw cap has a bell-shaped extension 4 in the lower part, on the inside of which there is a base ring consisting of segments 8 in the upper part and a rear in the lower part intersection 9 is located. Between the segments 8 and undercut 9, a double ring is held, which consists of a retaining ring 5 and a ring 7, which are connected to one another via elastic webs 6. In the upper part of the screw cap, a seal 10 is arranged.
  • the mouth part of the bottle-like vessel has a screw thread 1, under which a bead ring 2 is arranged and above which there is a pouring rim 3.
  • the screw thread is designed as a trapezoidal thread.
  • the bead ring 2 is flared downwards, and its outer edge forms the angle a with the vertical axis.
  • the pouring rim 3 is tapered downwards, and its outer edge forms the angle ⁇ with the vertical axis.
  • FIG. 3 shows the cross section of the double ring, which is composed of a retaining ring 5, a locking ring 7 and connecting webs 6.
  • the double ring is fastened between the segments 8 and undercut 9.
  • the double ring consists of a retaining ring 5 and a locking ring 7 and the rings mentioned are connected to one another by means of webs 6. Retaining ring 5 and locking ring 7 are arranged in the same plane.
