Definitions

  • the invention relates to a closure with automatically opening closure flap, wherein the automatic opening of the closure flap is effected by an elastic, product-carrying tube.
  • EP1427647B1 discloses a closure formed, in particular for dispensing beverages, with an elastic, product-carrying tube, one end of the tube being fixed in the closure.
  • the closure furthermore has a closure cap which is hinged to the closure body and, in the closed position, engages the tube against. Sealing element squeezes, so that a product delivery is prevented by the corresponding cross-sectional constriction of the hose.
  • the cap To open the closure, the cap must be unlocked and folded so that the tube is upright in its product dispensing position. This must be the Locking container to be fixed in one hand of the user, while the shutter is opened as described above with the other hand.
  • EP1427647B1 known closure unsuitable to seal a surfactant-containing product, such as something a detergent or cleaner for textiles, household goods, household surfaces, for human skin or hair from accidental leakage, especially in an over-head position.
  • a surfactant-containing product such as something a detergent or cleaner for textiles, household goods, household surfaces, for human skin or hair from accidental leakage, especially in an over-head position.
  • the object of the invention is therefore to overcome the disadvantages known from the prior art and to provide a cost-producible closure, which makes it possible to open the closure with one hand in a simple and convenient way.
  • the object is achieved by a closure having the features of claim 1 and a packaging having the features of claim 19.
  • closure according to the invention is that no separate spring element is required for the formation of the self-opening mechanism, since the product-carrying, elastic hose acts both for product delivery from the container and as a spring element. This allows the self-opening function of the closure to be realized in a very cost-efficient manner.
  • a closure flap in the sense of this application is a closure means arranged on the closure which serves alone or in conjunction with the closure for closing a product discharge opening.
  • closure flap can be designed as an outer flap, inner flap or closing flap, flap lid, cam cover, bayonet closure lid, hinge lid, sliding lid, snap lid, clamping lid, screw cap, slip lid, overcap lid or the like.
  • closure flap fixedly but movably on the closure so that the closure flap does not unintentionally detach from the closure when the closure is opened.
  • closure flap in one piece on the closure wherein it is particularly advantageous that the closure flap in this embodiment can be articulated on the closure.
  • material fatigue can occur in the vicinity of the hinge line, which can lead to crack formation and complete detachment or to a changing coupling behavior, depending on the structural design.
  • the shutter is movably connected to the shutter via a hinge. Due to the storage, the movement of the closure flap does not lead to any wear that is relevant for the life of the closure.
  • the means for fixing the hose to the closure flap comprise all material, force, and / or form-fitting fixing means which appear suitable for the person skilled in the art.
  • the hose may be glued to the closure flap.
  • the fixation means can also be formed as a sleeve arranged on the closure flap, through which the tube can be passed and which at least partially surrounds the tube.
  • the closure flap may include means for narrowing the tube cross-section.
  • an adaptation or adjustment of the metering can be done by adjusting the respective tube cross-sections.
  • the product delivery as well as the force necessary for the automatic opening of the closure is realized in the closure according to the invention by a product-carrying, elastic tube.
  • the deformation of the elastic tube as the closure closes creates a force against the deformation by the elastic tube and causes the tube to spring back to its original position when the force inducing the deformation is removed from the tube.
  • the tube has a certain elastic bias in the dispensing position. This can be effected by forming an angle ⁇ greater than 5 ° between the longitudinal axis of the tube in the product delivery position of the closure flap and the longitudinal axis of the tube in the untensioned state of the tube.
  • the hose is preferably made of an elastic plastic material.
  • the tube is made of a silicone material.
  • the closure comprises an opening aid for releasing the latching connection between the closure flap and closure, so that upon actuation of the opening aid, the closure is automatically moved out of the closure position into the product dispensing position by the spring effect of the tube.
  • the opening aid may be formed as a finger recess on the closure, wherein the finger recess represents a recess below the locking element, in which a finger is inserted in such that it can be moved under or behind the shutter to release the latching connection.
  • a stabilizing element in the sense of this application is a component which is movably designed on and opposite a closure and can be moved from a first position, in which the closure can not be stably positioned on a substantially horizontal surface, into a second position in such a way that in this second position of the stabilizing element, the closure can be positioned so as to be stably over head on a substantially horizontal surface such that in the over-head position of the container at least a part of the closure, in particular the closure head, and at least a part of the closure in the second Position stabilizing element form the base of the closure.
  • the stabilizing element is designed as a bracket.
  • the bow shape has the advantage of providing a comparatively elongated, linear support edge, which serves to support the closure in the overhead position.
  • the stabilizing element can be movable relative to the closure by means of a rotary movement, a linear movement or a combination thereof.
  • the stabilizing element may be pivotable, extendable, hinged, extendable, etc.
  • the stabilizing element may be formed as a flap, strap, stamp, cylinder or the like.
  • the stabilizing element biases a traverse, which encloses the footing of the closure on a horizontal flat surface in the overhead position.
  • the support points of the shutter on the horizontal plane in this case form the support points of the polygon, when the support point is substantially punctiform or the sides of the polygon, when the support point is substantially linear.
  • the polygon can be designed in particular as Dreieich, truncated cone, square, rectangle, trapezoid, parallelogram.
  • the projection of the center of gravity of the container arranged on the closure is perpendicular to the horizontal plane within the standing surface of the closure spanned by the traverse.
  • the center of gravity of the container relative to the center of gravity of the support surface is slightly displaced in the direction of the support line formed by the bracket, whereby the stability of the closure with the container can be further increased.
  • the closure flap is fixed in the closed position by the stabilizing element shaped as a pivotable bracket in the closed position.
  • the bracket and the flap are firmly connected. This has the advantage that the bracket is moved during the transfer of the flap from the delivery position to the closed position and is positioned in the closed position of the flap of the bracket in its overhead standing position. The shutter is thus automatically prepared with the shutter closed for positioning in the overhead position.
  • the stabilizing element and / or the support region of the closure may be provided with a non-slip material.
  • the stabilizing element can be coupled with spring elements, which automatically transfer the stabilizing element into the second position when releasing the stabilizing element from the first position by means of the spring action.

For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note”, “middle note” or “body note” ) and “base note” (end note or dry out).

  • the colorants When choosing the colorant, it must be remembered that the colorants have a high storage stability and insensitivity to light as well as not too strong affinity to glass, ceramic or plastic dishes. At the same time, it should also be taken into account when choosing suitable colorants that colorants have different stabilities to the oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the detergents or cleaners varies. In the case of readily water-soluble colorants, colorant concentrations in the range of a few 10 -2 to 10 -3 % by weight are typically selected.
