Definitions

  • the present invention relates to an easy-open valve closure for bottles, comprising a stationary and bottleneck-mounted valve inner part having a Ventilstop- fen and means for sealed fixing on the bottle neck, and with an axially movable valve outer part, in which a valve opening for the Engaging the valve plug and having a screw cap connected to the valve port having an internal thread with a nominal radius r and engaged with the external thread of a threaded nozzle, which is fixedly connected to the valve plug.

  • valve outer part is formed by a screw cap, but which has a larger diameter
  • screw cap valve whose screw cap has a relatively large diameter (eg greater than 25 mm) has found, inter alia, use in bottles with liquid detergents, the existing generally plastic bottles can be compressed so as to be able to easily dose the exiting amount of liquid with the valve open.

As cycling, running or the like, to be used. The athlete should (and wants to) so while exercising his sport can drink from the bottle by axially pulling the valve outer part slightly, thereby opening the valve and into the mouth, then by sucking or pressure on the outside of the bottle the drink in the Mouth without the risk of spilling or splashing the beverage on the body or clothing of the athlete.
  • the valve outer part is secured to the inner part so that it can not be completely withdrawn from the inner part, but essentially only between a closed and an open position is axially movable back and forth.
  • valve plugs and also the outer parts of the push-pull closures are relatively firmly in their closed position, so that they do not accidentally come loose during vibrations, and it requires some force to pull the valve outer part out of the valve plug or conversely a valve plug out of the valve plug Pull out valve opening. For this you generally need both hands. Opening such a closure by means of the teeth, by gripping the valve outer with the teeth and pulling on the bottle, is relatively risky and can lead to damage or loss of teeth, so that it is practiced by only a few users.
  • the screw cap has approximately the shape and size of the valve outer parts of the known push-pull closures and should have an outer diameter which is not greater than 25 mm, preferably not greater than 20 mm. Accordingly, the nominal diameter 2r of the internal thread of the screw cap (and correspondingly also the nominal diameter of the external thread of the threaded nozzle) is relatively small and is typically of the order of 8 to 15, preferably in the range of 10 to 12 mm.
  • this screw cap does not need a radially protruding upper edge, which possibly serves as a grip aid in push-pull closures, in order to be able to exert a corresponding axial pull for opening the valve on the closure.
  • the axial movement is generated by a rotation of the screw cap.
  • an actuating lever which extends radially outward from the screw cap, so that the radius of curvature R defined by the radially outer end of the lever is at a distance from the axis of the screw cap which is at least 20 % is greater than the nominal radius r of the internal thread.

  • the screw cap has an actuating lever in the form of a radial extension whose radially outer end of the axis of the screw cap has a greater distance than the outer shell of the screw cap, which is typically cylindrical or slightly conical or cylindrical stepped and also mostly relatively smooth.
  • This operating lever can rest for example on the top of a radial extension of the valve inner part.
  • a bottleneck on which such a closure is seated has a much larger diameter than the axially movable valve outer part of a push-pull closure and the associated inner neck of the valve inner part.
  • the valve inner part typically has, below this valve stub, a radially significantly widened section with a closure foot which forms the transition to the further bottleneck, is placed on the neck of the bottle and produces a tight connection between the edge of the bottle neck and the valve inner part.

Abstract

L'invention concerne une fermeture à valve (10) facile à ouvrir destinée à des bouteilles, comprenant un élément intérieur de valve (1) fixe qui peut être placé sur le col de la bouteille et qui comporte un bouchon de valve (2) et des dispositifs (22, 23) permettant la fixation étanche sur le col de la bouteille. Ladite fermeture à valve comprend également un élément extérieur de valve (11) mobile axialement qui comporte une plaque supérieure (14) munie d'une ouverture de valve (12) pour la mise en prise avec le bouchon de valve (2) et un capuchon à vis (13) relié à la plaque supérieure (14), lequel est doté d'un filetage intérieur (18) présentant un rayon nominal (r) et est en prise avec le filetage extérieur (8) d'un raccord fileté (4) qui est relié de manière fixe au bouchon de valve (2). L'invention vise à proposer une fermeture à valve de ce type qui d'une part peut être utilisée de manière habituelle comme une fermeture push-pull et prend appui de manière fixe et étanche sur l'élément de valve intérieur même en cas de secousses normales, et qui d'autre part peut être ouverte facilement et rapidement d'une seule main. A cet effet, selon l'invention, le capuchon à vis (13) est relié de manière fixe à un levier d'actionnement (16, 15 ; 16') qui s'étend radialement vers l'extérieur à partir du capuchon à vis (13), de sorte que le rayon de levier (R) défini par l'extrémité extérieure radiale (15, 16b) du levier d'actionnement (16, 15 ; 16') présente par rapport à l'axe du capuchon à vis un écartement qui est supérieur d'au moins 20 % au rayon nominal (r) du filetage intérieur (14).
