Definitions

  • the invention relates to a closure element according to the preamble of claim 1.
  • Such storage containers are regularly provided on their neck with an external thread onto which a capsule-like closure is to be screwed.
  • Tubes with a screw-on cap, but also bottles with a screw-on cap, each of which has an essentially pasty, sauce-like, ie highly viscous or liquid, low-viscosity content, require the capsule-like cap to be unscrewed each time it is removed.
  • the contents are then pushed out through the neck by exerting pressure. Toothpaste tubes are a typical example. Bottles have to be tipped after opening. A low-viscosity, i.e. highly liquid content can only be poured out in certain predetermined amounts, taking special precautionary measures into account.
  • US Pat. No. 4,051,984 discloses a container with a metering attachment, in which a portion of pasty container contents can be divided off by means of a slide and dispensed through a pouring opening which is closed by a flap in the idle state, the closure flap also causing the mass dispensed to be "cut off", this flap automatically returns to its rest position due to the action of gravity. Excess mass remains in an antechamber and can flow back into the supply from there. The "cutting off” under the effect of gravity is incomplete and leads to a run-on of the container contents and to smearing of the outside of the container. US Pat. No.
  • 4,057,177 relates to a tube or bottle closure, suitable for dosing viscous masses. Thereafter, a two-part closure is placed on the neck of the container, in which the outer closure part can be moved axially outward and the inner closure part is designed as an essentially rigid insert, a storage chamber being formed between the two closure parts and communicating with the mass via open channels.
  • Supply is connected and which has a valve which opens during the axial outward movement of the outer closure part and which allows the viscous mass to exit through an outlet pipe.
  • the valve can be a valve provided with overflow slots, but it can also be designed as a cone valve.
  • An aeration valve similar to a "flutter valve" prevents the formation of an inadmissible negative pressure in the container.
  • US Pat. No. 4,061,254 also describes a largely similar closure attachment for tube-like storage containers for pasty or viscous masses.
  • US-PS 4 408 702 This relates to a tubular or bottle-shaped container for pasty or viscous masses, with a closure part on the neck of the tube or is placed on the bottle, which, under pressure, also opens the container wall above the pressure of the mass contained in the container and releases an outlet opening.
  • the part closing the opening moves axially with a conical seat; in the axial movement, an elastic member is deformed so that it acts as a restoring element, the force caused by it being less than a force exerted by a squeezing pressure exerted on the contents of the container, and that and after the pressure is released, for a resetting of the closure part Care.
  • a design according to US-A 2 028 843 can only be carried out and is functional if the container neck has a square or rectangular cross section.
  • the spring is not a tension element but a pressure element and is also not arranged inside the container or container neck, surrounded by the container contents.
  • the flap is located inside the neck - so the neck appears to be optically open.
  • the flap is loaded by a compression spring, which acts on the flap from the outside and is not inside the container or its neck, surrounded by the contents of the container.
  • those known designs are significant, according to which the existing screw closure is replaced by a preferably also screwed-on cap, which is provided with a flap-like closure of the opening, this flap-like closure also being held in the closed position by means of an externally attached spring-like element and wherein this spring-like element yields at increased internal pressure and can open the flap-like closure for dispensing the contents of the container.
  • the known solutions have various disadvantages, which essentially consist in the fact that the container contents can not only remain in the seat of the flap-like closure and harden there, but also smeared the spring-like locking device and thus interferes with its function, especially when the contents of the container dry out, solidify or stick.
  • the lid is designed as a flap, articulated on the edge of the removal opening on the container neck and the tension element connecting the spring to the lid is fastened to the inside of the lid at a point which is expedient as far as possible from the articulation of the lid.
  • the arrangement of the closing device for the container closure in the interior of the container means that hardening, sticking or smearing of the contents of the container in the area and in the vicinity of the container opening do not have a disadvantageous effect on the functions of the closure or the spring action can. Rapid drying out, hardening or sticking of the contents of the container is impossible inside the container. This ensures a constant, uniform function and effect of the closing spring for the container closure, without significantly narrowing the lumen of the neck.
  • the spring forming the restoring element is advantageously designed as a leaf spring and is fastened at one end in the neck of the container below the lid level and bent under pretension projecting into the neck space at its other, free end via the pulling element with the outwardly movable region of the lid.
  • the design can be chosen such that the end face of the neck is partially rigid on a straight edge, which can be a chord of the surface, is connected to the cover by means of a hinge, the rigid end face being designed as a leaf spring and there with spring attached at one end protrudes approximately axially parallel into the neck space and is connected at its free end via the pulling element to the unfolding region of the cover.
  • the tension element can be a thread or a rod, the rod being articulated to the leaf spring and / or the underside of the cover.
  • the arrangement can also be such that a rigid rod is present instead of the leaf spring, at the free end of which an elastic element, for example in the form of an elastic band or a small spiral spring, is arranged instead of the tension element is.
  • the arrangement can also be such that, in the case of a pivotable lid in a hinge, the pulling element or the elastic return element inserted on its side is mounted in the form of an elastic band, for example, in such a way that when opened wide by hand Lid a dead center is overcome, so that this, if desired, remains open in its wide-open position and closes again after only a small push and thus overcoming the dead center of the locking device.
  • This has the advantage that the removal or squeezing opening of the container can be opened completely and remains open, so that when the contents of the container are squeezed out, the closing force of the container closure can no longer be overcome.
  • the arrangement according to the innovation is advantageous such that the lid with its articulation and preferably also the spring are arranged in an insert which, with its outer boundary, is adapted to the inner shape of the container neck and can be inserted into it.
  • the stake can advantageously be provided with locking lugs that overlap the outer edge of the container neck and lock with the inner edge of the neck during the transition into the interior of the container.
  • the insert expediently consists of a ring which lies essentially against the inside of the container neck directly inside the opening and from which at least three rods with end claws protrude parallel to the axis, these end claws being designed such that they align with the inner edge of the neck during the transition into lock the interior of the container.
  • the upper part 1 of a container is shown broken off, which runs into the neck 2 of the container with the removal opening 3.
  • the container can be a tube or a bottle.
  • the bottle can be made of a resilient material, preferably plastic, and can preferably be compressed somewhat by forming flat, membrane-like side walls, so that pressure is exerted on the contents of the container.
  • the leaf spring 4 is fastened in the vicinity of the upper edge of the container neck 2, so that it projects downward approximately parallel to the axis.
  • This leaf spring 4 is attached at its free end lying towards the container 1 in a somewhat deflected position via a tension element 8 with the point 7 on the lid 5 which can be opened on the hinge 6. It can be seen that when the cover 5 is opened via the tension element 8, the leaf spring 4 which is stuck at the upper end of the container neck 2 is deflected less or more with its lower end depending on the opening of the cover 5 and thus also exerts a greater or lesser spring force.
  • the lid 5 When the contents of the container 1 are pressed, the lid 5 is opened against the force of the leaf spring 4, so that the contents can escape as long as the pressure on the contents of the container persists. After release of this pressure, the leaf spring 4 pulls the lid 5 back against its seat and thus closes the container.
  • the exemplary embodiments described so far can also be designed such that not a leaf spring 4, but instead a rigid rod is used, but on the other hand an elastic, preferably thread-like element is used instead of the tension element 8, such as a rubber thread ; it can also be a thin coil spring.
  • the opening 3 is partially covered with a fixed end face 9 and the lid or flap 5 is hinged to this end face with a hinge 6.
  • a rigid rod 11 is fastened at one end, which, approximately axially parallel in the direction of the container 1, is advantageously bent somewhat at its free end 11 a, in the opening direction of the lid or the flap 5 the pulling element is fastened at the free end in the form of a rubber thread 10, which is fastened at its other end to a flap 5 at an opposite hinge 6 of the cover 7, a point 7 distant there.
  • FIG. 3 it is shown how the container closure according to the invention is connected to the container, with the drawing of the leaf spring and the tension member connecting the leaf spring to the closure being omitted for simplification.
  • a half-shell resting on the inside of the container neck 7 or a half-ring 12 can be formed on the inside of the end face 9.
  • This half-shell or half-ring 12 can be designed with its free ends 13 projecting beyond the end face 9 in such a way that it is clamped in the neck 2 in a resilient manner.
  • three locking lugs 14, which are arranged at intervals from one another, can expediently also be arranged underneath the ring 12, which overlap the inner edge 15 of the neck 2 at their free ends during the transition into the interior of the container 1 with projections 16 projecting outwards.
  • the stake is now within the neck 2 of the container with the end face 9 resting on the free edge of the neck on the one hand and with the locking lugs 16 on the other hand firmly secured in the neck.
  • the insert can of course also be designed such that it forms a sleeve which extends from the outer edge of the end face and is fixedly connected to it and crosses the neck and which is provided with an internal thread, is screwed onto the external thread of the neck.
