Definitions

  • the present invention relates to a container closure in which a closure bottom is moved toward a closure top by means of a screwing movement of a rotary body, thereby pushing a sealing element outwardly, and a container having such a closure.
  • Such closures are particularly suitable for the closure of storage containers that are used for storage of food.
  • plastic containers are widely used, which are closed by a plastic lid, which has along its edge region a groove for receiving the upper container edge.
  • Container contents can be stored and removed in a simple manner, whereby such containers are well stackable even when closed and therefore easy and space-saving stowed.
  • screw caps which are well suited for small container openings, such as bottles, but which are unsuitable for larger and non-round openings.
  • EP 0 582 028 describes a closure for the hermetic closure of containers, wherein the closure has an inner and an outer element, between which an elastic seal is arranged.
  • the inner element can be screwed into the outer element.
  • the seal between the two elements is pressed together and pushed outwards, thereby sealing the passage between the container and the inner element, thus closing the container opening.
  • a disadvantage of this closure is in particular the fact that the inner element and / or the outer element rub against the seal during closure and opening of the closure, which thereby wears off.
  • the closure is also only suitable for round container openings.
  • the lower closure element has a screw which extends through the upper closure element upwards.
  • Closure is closed by screwing a sleeve-shaped body onto this screw.
  • the two closure elements are thereby attracted to each other, wherein the intermediate sealing element is pressed together and pressed to the outside.
  • the container opening is thereby sealed.
  • the closure should also be suitable for differently shaped container openings and not limited exclusively to, for example, round or rectangular openings.
  • the closure should allow certain manufacturing tolerances with respect to the dimensions of the container opening.
  • the present invention thus provides a closure for a container with the following features:
  • a rotary body on which a first engagement structure is formed.
  • the closure lower part has a second engagement structure, in which the rotary body engages with its first engagement structure, so that it can be rotated between an opening and a closing position.
  • the upper closure part, the lower closure part and the rotary body are arranged such that the rotary body moves the upper closure part and the lower closure part towards one another during a movement from the opening into the closing position.
  • the sealing element is also such arranged so that it is pressed towards each other during a movement of the closure base and the closure top to each other outwards.
  • the rotary body protrudes at least in its closing position into the passage opening of the closure upper part.
  • An advantage of such a closure is that it is not only suitable for closing containers with a round container opening, but can be designed for any shape of container openings.
  • the container may also have production-related tolerances, in particular with respect to the dimensions of its opening to be closed, and is nevertheless still easily closable by such a closure according to the invention.
  • the first and the second engagement structure may be, for example, interlocking threads or a bayonet closure.
  • first and the second engagement structure are configured such that the rotary body can be brought from the opening into the closing position by means of a combined rotational and translational movement.
  • the second engagement structure is attached to the closure bottom, and the rotation body is preferably insertable through the passage opening of the closure top into the second engagement structure of the closure base.
  • first engagement structure to the outside and the second engagement structure inward.
  • the rotary body can thus be used in the second engagement structure.
  • the rotary body can be screwed into the closure base and has a handle which can be gripped through the passage opening.
  • the rotary body is thereby optimally integrated in the remaining closure, which improves the stackability of the closed container with the closure.
  • the thus configured rotary body also preferably has a circumferential side wall having a cylindrical shape which is closed on one side by a surface, wherein the handle is disposed radially within the side wall.
  • the rotary body is actuated by the user via a handle arranged in its interior. This is particularly advantageous because the handle thereby the remaining rotary body not surmounted, whereby the stackability of a closed container with such a closure is in turn improved.
  • the rotary body has a first bearing surface
  • the closure upper part has a second bearing surface.
  • the rotary body strikes against the second bearing surface with this first bearing surface, in order thereby to take along the closure upper part.
  • the movement of the closure bottom and the closure top towards each other due to movement of the rotating body from the opening to the closing position is thereby accomplished in a particularly simple and effective manner.
  • mutually complementary latching elements are mounted on the first and the second bearing surface, which engage in each other at least in the closing position, but preferably also in the opening position, to the user reaching the respective position of the rotary body noticeable.
  • first and the second engagement structures are mutually complementary threads.
  • This may be an external thread formed on the rotary body and an internal thread formed, for example, on the closure base.
  • the rotary body at least in its closing position, projects beyond the closure top at no point. It is thereby made possible for a container closed with such a closure to have a substantially flat upper side.
  • a container closed with such a closure has no significant upwardly projecting parts, a stacking of several, closed with such a closure containers one above the other is much easier. It can also be stored on the sealed container in an optimal way other items.
  • Such a sealed container claimed accordingly much less space during storage.
  • the sealing element is preferably attached to the closure bottom and thereby advantageously formed as a sealing lip.
  • the sealing element which is preferably designed to be flexible, but could also be attached to the closure top or loose, for example, as a sealing ring, be arranged between the lower closure part and the upper closure part.
  • the sealing member is attached to the closure lower part
  • an embodiment is particularly preferred in which the sealing element is formed as a sealing lip, which is inclined in the opening position of the rotary body to the closure top, and is arranged such that it during a movement the closure base and the closure top each other in its inclination is variable.
  • the closure top can then, for example, have a downwardly facing surface, which presses the sealing element toward one another during a movement of the closure bottom part and the closure top part downwards and thus outwards.
  • closure upper part, the closure base and the rotary body are each formed in one piece. They can be made for example by injection molding.
  • the closure bottom part and the sealing element are jointly formed in one piece and produced, for example, in a two-component injection molding process.
  • the closure upper part and the closure lower part may each have complementary snap elements, which are designed such that they limit a movement of the closure lower part relative to the closure upper part in the vertical direction in the latched-in state.

Abstract

L'invention concerne un système de fermeture pour un contenant (1). Ce système de fermeture comporte une partie supérieure (2) présentant une ouverture traversante (23), une partie inférieure (3), un élément d'étanchéité (5) et un corps rotatif (4). Le corps rotatif (4) qui présente une position d'ouverture et une position de fermeture comporte une première structure de mise en prise (45) conçue pour être mise en prise avec une seconde structure de mise en prise (34) située sur la partie supérieure (2) ou sur la partie inférieure (3). La partie supérieure (2), la partie inférieure (3) et le corps rotatif (4) sont agencés de telle sorte que, lors d'un mouvement s'effectuant de la position d'ouverture à la position de fermeture, le corps rotatif (4) déplace la partie supérieure (2) et la partie inférieure (3) l'une vers l'autre, ce qui comprime l'élément d'étanchéité vers l'extérieur.
