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.
- DE-OS-101 60 362 which discloses a closure cap for a glass bottle
- the closure cap has a collar which engages over the mouthpiece of the glass bottle.
- the shell inner surface of the collar has inwardly projecting latching projections, which can interact positively with undercuts provided on the outside of the neck of the bottle.
- 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.
- 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 an articulation position and returns from this deflection substantially independently in its rest position
- the latching protrusion may thus function substantially like a leaf spring
- the at least one latching protrusion may be formed on the closure base However, especially if more than one latching protrusion is used, the latching protrusions may abut
- the wreath with the latching projections can be permanently connected to the closure bottom part, for example by projections formed on the rim, which are in the lower part of the closure l engage recesses formed complementary to the projections, or vice versa.
- the closure bottom may be made of a different plastic than the wreath with the locking projections.
- the locking projections may be made of a viscoelastic plastic material
- 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 used for the repeatable closing of storage containers.
- the reservoirs can hold liquids, which may also be tough, pastes or pourable material.
- 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 covered by a blanket! lockable.
- the lid may be connected captively to the closure bottom and form the container closure.
- the undercut and / or a latching with the undercut portion of the locking projection in the circumferential direction have a bevel, which allows separation of the latching by a relative radial movement of Be hold rte 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 adjoins the collar and whose outside diameter can be larger than the collar, rests against an edge bounding the mouth in the pouring direction.
- a radial movement that is to say a rotation of the container closure about the central axis, can cause the latching projection to engage one another the undercut can 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 Intersection 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 with the undercut to produce a reliable and axially non-detachable connection.
- the insoluble in the axial direction connection is achieved essentially by positive engagement and orsprungs only to a negligible part by the biasing force of the catch.
- 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 can be displaced through the at least one opening.
- the at least one latching projection can be arranged on an outer wall of the collar facing away from the central axis or on an inner wall facing the central 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 ats 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 of a reversibly 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 each other.
- the collar of the container closure has a base.
- the base is located opposite a collar which, when the closure base is inserted into the mouth, projects beyond the mouth.
- the at least one latching projection is integrally formed on the base and extends in the direction of the collar.
- the locking projection could also be non-detachably connected to a base opposite side or to a side adjacent to the base. It has been found, however, that the extraction forces acting on the container closure mounted in the mouth are highest when the locking projection is connected to the base.
- the collar is integrally formed on a fürrnessergrösseren covenant, wherein between the collar and collar an annular shoulder is formed.
- annular shoulder may be formed, for example, as a cone, which tapers from the collar in the direction of the collar. The cone can acting sealingly 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 designed as an annular surface extending essentially 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. According to a further embodiment of the invention, the at least one latching projection is substantially L-shaped.
- the at least one L-shaped locking projection has a first axial leg whose first end is inextricably connected 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 can be the reversibly elastic section, which acts similarly to a leaf spring.
- the second leg which is generally shorter than the first leg, interacts with the undercut in the mouth such that the container closure, when in the muzzle locked, in the axial direction of the mouth is not destructively removable.
- the predetermined angle is usually about 90 °. However, the predetermined angle may vary depending on the design of the mouth.
- the second leg is formed as a wedge.
- the thicker part of the wedge may face the first leg and the thinner part of the wedge may face away from the first leg.
- This embodiment of the wedge may have the advantage that the container closure as such is easy to demold, since there are no undercuts.
- the wedge preferably has a first wedge surface facing away from the first limb and a second wedge surface facing the first limb.
- the first wedge surface and the first leg may include an angle of between 75 ° and 90 °, preferably between 80 ° and 89 °, and more preferably between 82 ° and 88 ° Further, the wedge shape of the second leg may prevent the second leg evades when pulling on the container closure, as could happen if the second leg would have only the wall thickness of the first leg.
- 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 the ring heel. 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 first sealing surface formed on the collar can be prevented at a portion of the orifice not belonging to the second sealing surface of the orifice. A damaged sealing surface can lead to leaking of the container and container closure combination.
- a sealing surface is formed on the first collar portion.
- a bottom is formed circumferentially on an inner wall of the collar. The soil begins above the at least one breakthrough.
- the term "above” means that when the container is standing on its bottom and the container closure is inserted into the mouth opposite the bottom, the bottom between the aperture and collar is rooted on the inside wall of the collar.
- the bottom can be flat, domed or stepped
- the bottom can also be funnel-shaped, so that the small opening of the funnel is the inlet opening of the pouring spout, and by designing the bottom in this way, a residual emptying of the stored contents can be aided in.
- the bottom according to this embodiment can, if the container closure
- the container closure can be tamper-proof with respect to the at least one latching projection in connection with the base 16.
- the first collar portion may be formed entirely as a sealing surface or even only one preferably circumferential portion of the first collar portion.
- the sealing surface can cooperate with a corresponding with the sealing surface portion of the mouth in such a way that leakage of stored in the container contents between the container closure and mouth is avoided.
- the at least one opening can be arranged with the relevant at least one latching projection in the second collar section.
- the first collar portion and thus the sealing surface may also be formed above the at least one opening.
- the second collar portion is formed as a sealing surface.
- a bottom is formed circumferentially on an inner wall of the collar. The bottom is arranged below the at least one opening.
- the term "below” means that when the container is standing on its bottom and the container closure is inserted into the mouth opposite the bottom, the bottom in the area of the base is rooted on the inner wall of the collar.
- the bottom can also be designed funnel-shaped, so that the small opening of the funnel is the inlet opening of the pouring spout be supported the pouring spout.
- the floor according to this embodiment can not prevent access to the at least one locking projection when the stopper is mounted in the mouth, but access to the floor may be difficult to access.
- the bottom may be step-shaped and have an outer, annular edge region and an inner floor surface which is raised in the direction towards the collar and which adjoins the edge region via a step.
- a height of the step in the direction of the collar will be about as large as the height of the locking projection or larger.
- the step will be formed in connection with the annular edge region such that at a confluence of maximum tolerances of the mouth and Be Strukturerversschtusses the locking projection is so far deflected that the locking projection during assembly of the container closure into the mouth until reaching its end position the stage not contacted. A contacting can hinder the radial deflection of the latching projection. As a result, the locking projection may possibly be damaged.
- the second collar portion may be formed entirely as a sealing surface or only a preferably peripheral portion of the second collar portion.
- the sealing surface can cooperate with a corresponding with the sealing surface portion of the mouth in such a way that an outlet of the stored in the container content between Benzotterver gleich and mouth is avoided.
- the at least one opening can be arranged with the relevant at least one latching projection in the second collar section. As a result, the sealing surface will generally be formed on the second collar section below the at least one opening.
- Such a configuration may be particularly suitable for pourable material better than the embodiment described in the previous paragraph, in particular, if the container closure is designed to be removable from the mouth.
- sealing surfaces on the collar sections are cone-shaped, with the diameter of the sealing surfaces increasing in the direction of the collar of the container closure.
- the collar sections could also be cylindrical. However, this would require fabrication of both the mouth and the occluder closure with close tolerances. However, tight tolerances make production more expensive.
- the conical configuration of the sealing surfaces can form the advantage that even larger production tolerances can be compensated thereby, without it being possible for contents to pass from the container between the sealing surfaces of the collar sections and the corresponding sealing surfaces of the mouth.
- the subject of the present invention is also a container for receiving a container closure described above, the container having an opening on which an undercut is formed such that the undercut and the at least one latching projection of the container closure, when engaged with each other, form a permanent in the direction of the central axis of the container closure catch.
- the mouth is madebil- det to sealingly cooperate with the sealing surface of the first collar portion or the sealing surface of the second collar portion of the collar of the container closure.
- the sealing surface arranged on the collar can be assigned a corresponding sealing surface in the mouth, so that an escape of the contents stored in the container between these sealing surfaces is effectively prevented by an interaction of these sealing surfaces.
- the container is a bottle or a tube, the mouths of which can be closed by the container closure described above.
- the mouth has a front ring section with a first inner diameter and a rear ring section with a second inner diameter, wherein the front ring section extends from an edge delimiting the mouth in the direction of a container bottom opposite the mouth, and the rear ring section connects to the front ring portion, wherein the second inner diameter is smaller than the first inner diameter.
- the inner diameter of the ring sections can be dimensioned so that they correspond to the outer diameters of the collar sections.
- the undercut is formed in the mouth as a depression or increase.
- the depression can be a groove or ut.
- the increase we will usually be formed as a bead, which is arranged as a material accumulation at the mouth.
- the bead can also be created that the mouth is constricted on its outside at the appropriate position.
- a combination of a container as described above and a container closure, also as described above, is proposed.
- a sealing ring is arranged between an end face of the mouth and the annular shoulder of the container closure.
- this end face will be flat.
- a predetermined acting in the direction of the central axis of the BenzoiterverBankes axial force may be applied. This axial force can be applied by the interaction of the at least one latching projection and the undercut.
- a distance between the end face of the mouth and the annular shoulder on the collar, when the at least one locking projection and the undercut are engaged be less than the thickness of the sealing ring.
- a seal between the mouth and the sealing surfaces formed on the collar may possibly be dispensed with.
- the sealing ring can also be integrated, for example captive to the closure bottom.
- the sealing ring can be replaced by a second component which is sprayed onto the closure bottom part, as is possible, for example, by means of a co-injection spraying method.
- the sealing ring can then be made of TPE, for example.
