Definitions

  • the invention relates to a container closure according to the preamble of claim 1.
  • Plastic closures for containers are usually screwed or plugged onto a spout section, wherein a collar of the closure engages over the spout section.
  • a collar of the closure engages over the spout section.
  • Exemplary of a variety of such closures is the DE-OS-101 60 362 mentioned, which discloses a cap for a glass bottle.
  • the cap has a collar that engages over the mouthpiece of the glass bottle.
  • the shell inner surface of the collar has inwardly projecting latching projections, which can cooperate positively with the outside on the bottleneck provided undercuts.
  • a hinged lid is arranged, which is separated via a predetermined breaking point of the collar when the bottle is opened and the contents of the bottle to be made accessible.
  • Such closures can also be designed as a flip-top closure or as a rotary closure which can be screwed onto a spout section of a bottle.
  • the EP-A-1 086 903 discloses a dispenser package for a flowable product comprising a plastic container having an axially extending cylindrical neck with a radially inner throat surface, an adapter of an integrally molded plastic structure having a dispensing opening and a cylindrical wall received within the neck, an outer wall surface is opposite to the radially inner neck surface.
  • the inner throat surface has a radially opening peripheral channel and the outer wall surface has a radially protruding peripheral bead received in the channel to secure the adapter to the neck.
  • the neck inner surface has at least one circumferentially extending axial channel
  • the outer wall surface of the adapter is at least one axial lug or lug extending from the bead in the axial direction Channel extends to align the adapter circumferentially with respect to the neck.
  • a container closure made of plastic is proposed with a closure lower part, which can be fastened to an orifice of a container.
  • the closure lower part has a collar which can be inserted into the mouth of the container.
  • the at least one latching projection is reversibly elastically displaceable relative to the collar in the direction of a central axis of the closure lower part.
  • the at least one latching projection is designed in such a way that the at least one latching projection and an undercut formed in the muzzle, when they engage with one another, form a connection which is unsolvable in the direction of the central axis.
  • the proposed container closure can be made of the usual thermoplastically deformable plastics, such as PET, PP, PE and their blends by injection molding.
  • the collar of the closure base is usually formed as a circular hollow cylinder.
  • the term "reversibly elastic" is to be understood that the latching projection is displaced from its rest position under the action of a predetermined radially acting force by a predetermined amount in the direction of the central axis in a deflection position and from this deflection substantially returns to its rest position independently or springs back when the radially acting force is eliminated.
  • the locking projection can thus essentially function as a leaf spring.
  • the at least one latching projection may be formed on the closure base.
  • the latching projections may be arranged on a ring, wherein the ring may be an independent component, in particular a plastic injection-molded part.
  • the wreath with the latching projections may be permanently connected to the closure lower part, for example by projections formed on the rim, which engage with recesses formed in the closure lower part complementary to the projections, or vice versa.
  • the locking projections may be made of a viscoelastic plastic material, whereas the closure base may be made of a brittle hard plastic material.
  • the closure lower part with the at least one Locking projection can be in one piece.
  • the container closure may be designed to be inserted several times in the mouth of the container, which may be made of any material such as plastic, glass or metal, and removed from the mouth.

  • the container closure can be designed to be dense relative to the media stored in the storage container.
  • the container closure may have a removal opening such as a nozzle, which is usually closed by a lid. The lid may be connected captively to the closure bottom and form the container closure.
  • the mouth can, for example, have an undercut only in at least one section, wherein the section adjacent to the undercut in the circumferential direction is designed without undercut, as a rule smooth.
  • the undercut and / or a latching with the undercut portion of the locking projection in the circumferential direction have a slope which allows separation of the latching by a relative radial movement of the container closure to the mouth of the container or at least facilitated.
  • the container closure can be introduced into the mouth until, for example, a collar of the container closure, which outer collar diameter can be larger than the collar, adjoins the collar, at a rim delimiting the mouth in the pouring direction.
  • latching of the latching projection and the undercut can be achieved by a radial movement, thus rotating the container closure about the central axis be obtained.
  • a removal of the container closure can be obtained by being brought by a rotational movement of the locking projection on the slope out of engagement with the undercut.
  • the undercut of the mouth may be formed as a circumferentially extending radial projection, such as a bead, or as a circumferentially extending radial recess, such as a groove or groove.
  • the undercut can also extend over the entire circumference of the mouth.
  • the container closure may possibly be designed to be rotatable, but after the locking of the latching projection and the undercut with each other are non-releasably connected to each other. Since the latching projection is elastically reversibly displaceable in the radial direction, the latching projection can compensate for manufacturing tolerances of the mouth and the container closure in such a way that the latching closure engages in a reliable and axially non-detachable connection in engagement with the undercut.
  • the non-detachable in the axial direction connection is achieved essentially by positive engagement and only to a negligible part by the biasing force of the locking projection.
  • a first fixing element for example, can be formed on the container closure, which engages in a second fixing element which corresponds to the first fixing element and is formed in the mouth.
  • the proposed container closure may have the advantage that it can be constructed very compact and that less material is required for its production than container closures that engage over the container mouth.
  • the collar has at least one opening, wherein the at least one latching projection is displaceable through the at least one opening.
  • the at least one latching projection may be arranged on an outer wall of the collar facing away from the center axis or on an inner wall facing the center axis and opposite the outer wall, or on a wall of the collar delimiting the aperture.
  • more than one catch projection can be arranged in a breakthrough.
  • the locking projection in its reversibly displaceable, respectively resilient portion have a different wall thickness than the collar. In most cases, the breakthrough will be formed as a rectangle.
  • the locking projections may be arranged diametrically opposite or substantially regularly distributed over the circumference. This may have the advantage that the closure bottom, once introduced into an orifice, is held reliably.
  • a geometric configuration of a side of the central axis facing one corresponds reversibly elastic portion of the at least one latching projection and a geometric configuration of the central axis facing inner wall of the collar substantially together.
  • the side of the section facing the central axis can therefore be substantially flush with the inner wall of the collar facing the central axis. This may mean that in the present embodiment the side of the section facing the central axis is flush with the inner wall of the collar both in the direction of extension of the central axis and transversely to the direction of extension of the central axis.
  • the inner wall of the collar is designed, for example, as a circular cylinder
  • said side can be designed as a circular cylinder section with the same radius as the inner side.
  • the geometric configuration of said side and the geometric configuration of the inner wall facing the central axis may include a predetermined angle with each other.
  • the reversibly elastic portion may project radially beyond the collar.
  • the geometric configuration of a side facing away from the central axis side of a reversible elastic portion of the at least one locking projection and a geometric configuration of an inner wall facing away from the central axis of the inner wall of the collar, namely the outer wall substantially correspond to one another.
  • the collar of the container closure has a base.
  • the base is located opposite a collar that, when the closure bottom is inserted into the mouth, surmounted the mouth.

The cone can act in a sealing effect in cooperation with the mouth so that leakage of a substance stored in the container between the mouth and the container closure can be prevented.
  • the annular shoulder is formed as an annular surface extending substantially transversely to the central axis. This annular surface can serve as a stop when mounting the container closure in the mouth. Also, the annular surface may be formed as a sealing surface for a between the mouth delimiting edge and the annular surface arranged flat gasket.
  • the at least one latching projection is substantially L-shaped.
  • the at least one L-shaped latching projection has a first axial leg whose first end is inextricably linked to the collar and a second leg, wherein the first leg and the second leg include a predetermined angle and the second Leg is non-detachably connected to a first end opposite the second end of the first leg.
  • the axial leg may be the reversible elastic portion which acts similar to a leaf spring.
  • the second leg which is usually shorter than the first leg, cooperates with the undercut in the mouth in such a way that the container closure, when locked in the mouth, in the axial direction of the mouth is not destructively removable.

  • a continuous bottom is formed circumferentially on an inner wall of the collar.
  • This floor can also be designed such that it limits the collar at its outer edge, which is opposite to the annular shoulder. If the bottom is formed standing back against the outer edge, it will usually have a pouring opening, which can be closed by a separate lid. Here, the outer edge can serve as a stop for the lid. Appropriate solutions are well known from the prior art.
  • the collar has a first collar section adjoining the annular shoulder and having a first outer diameter, and a second collar section adjoining the first collar section having a second outer diameter, the second outer diameter being smaller than the first outer diameter.
  • the collar can be designed so that when the first or second collar portion or a portion thereof is formed as a first sealing surface, this first sealing surface only comes into contact with the mouth when the second sealing surface of the mouth corresponding to this first sealing surface is reached , Thus, scraping and associated possible damage to the collar formed on the first sealing surface on a not belonging to the second sealing surface of the mouth portion of the mouth can be prevented.
