Definitions

• the invention relates to a self-closing closure for installation in a dispensing opening in a container, cap part or the like.
• a known generic closure (DE-A-42 14 153) comprises a rigid upper part which is connected via a membrane-like flexible connecting wall to a rigid inner part, which on the one hand can be screwed onto a container neck and on the other hand from which a stationary sealing pin protrudes.
• the sealing pin can engage in a passage opening in the upper part if there is no external force acting on it.
• a lifting force on the upper part causes the sealing pin to be brought out of the sealing engagement with the passage opening.
• the known closure has a comparatively complicated, manufacturing-unfavorable structure.
• a particular disadvantage is that it is not suitable for being able to be adapted to a given configuration, for example the rounding of a container, without significantly impairing its appearance.
• a self-closing closure with a similar structure is also known from DE-A-23 40 319.
• the appearance of this closure is significantly impaired by an exposed connection wall.
• the invention has for its object to provide a self-closing closure of the type mentioned, which with a simplified, inexpensive and user-friendly structure offers the possibility for the greatest possible integration and adaptation to the configuration of the part whose donation opening is to be closed.
• a self-closing closure for installation in a dispensing opening in a container, cap part or the like, with an upper wall part containing a passage opening and a sealing pin which engages in the passage opening from the underside of the upper wall part and protrudes from an inner closure part and under the action a force exerted on the top wall part against a prestressing force can be brought from the sealing engagement with the passage opening
• the top wall part according to the invention at least on the top side having a configuration which can be adapted flush to the surface contour of the container and being designed to be elastically flexible at least in one actuation area, so that the actuation area below a hand force exerted thereon is elastically concavely deformable, and means are provided to convert the concave deformation of the actuation area into a relative movement between the di chaps and the passage opening.
• the closure is characterized by an upper wall part, which can be designed to be completely or partially flexible, so that a force exerted on it by an operator's finger or thumb can cause a concave indentation. Without such a carpet, on the other hand, the top wall part creates an essentially smooth outer surface, which is a continuation of the adjacent surface of a container or other Can represent component on which the closure is mounted. The closure therefore practically does not affect the external configuration of the component.
• the movement created by the indentation of the upper wall part under the said force is used with simple means in order to generate a relative movement between a through opening in the upper wall part and a sealing pin interacting therewith, so that the sealing pin can be disengaged from the through opening.
• a particularly preferred embodiment of the invention which is favorable in terms of production technology provides for this purpose that the sealing pin is pivotally held on the inner part of the closure and the bulge of the upper wall part can be transferred to the sealing pin via a simple transmission member.
• the inner closure part with the sealing pin could also be an integral part of the component, so that only the top wall part would have to be added.
• the upper wall part and the inner part of the closure can, however, also represent separate parts which are subsequently inserted into a dispensing opening of the component in question.
• an aesthetically pleasing smooth outer surface is obtained in the area of the dispensing opening, which is largely adapted to the configuration of the component and can be printed, for example, with advertising information such as the adjacent wall areas of the component, without the print image being impaired.
• FIGS. 1 and 1A Views a self-closing closure according to a first embodiment of the invention in the closing (Fig. 1) and release position (Fig. 1A), 2, 2A in views similar to FIGS. 1 and 1A a self-closing closure according to a second embodiment of the invention, and
• the self-closing closure according to the invention is arranged in a dispensing opening (not designated) in the wall 3 of a container 2.
• the closure comprises an upper wall part 6 which, as shown, can align flush with the container wall 3 on the upper side and is supported on supports 7, 8 formed on the container 2.
• the top wall part 6 can have any circumferential configuration adapted to the outline configuration of the dispensing opening in order to create a flush continuation of the curved container wall 3.
• a passage opening 9 is provided in the upper wall part 6 at a location near a radially offset circumferential area, into which a sealing pin 11 can engage in a sealing manner.
• the sealing pin 11 is on a closure inner part 10 integrally formed, and in particular on a resilient connecting member 12 in the form of, for example, a U-shaped cutout from the inner closure part 10, so that the connecting member 12, which carries the sealing pin 11 at one end, is connected to the inner closure part 10 at its other end.
• the link 12 can therefore be pivoted together with the sealing pin 11 out of the plane of the inner closure part 10, whereby it springs back into the starting position shown in FIG. 1 in the plane of the inner closure part 10 due to the natural elasticity of the material if there is no outer surface on the link 12 Acts force.
• the external force can be exerted by an operator's thumb or finger, as shown in Fig. 1A.
• the top wall part 6 is structurally elastic at least in some areas and / or consists of an elastic material, for example an elastomeric material, which yields under the action of an external force with the formation of a dent, as shown in FIG. 1A at 6 ', in the following also the actuating area called, is shown.
• a path transmission member 13 is also formed in the form of a tongue, which abuts with its free end on the underside of the upper wall part 6 or is in other suitable engagement, so that a movement of the upper wall part 6 at its actuating region 6 'to a rectified Movement of the link 12 can lead.
• both parts will spring back into the starting position shown in FIG. 1 as soon as the force exerted on the upper wall part 1 is removed.
• the grip When the parts are returned to the starting position, the grips Sealing pin 11 into the passage opening 9 in the upper wall part 6 in order to close it.
• the sealing pin 11 disengages from the passage opening 9, so that a medium in the container can flow outwards along the sealing pin 11 and through the passage opening 9, as indicated by the arrow in FIG. 1A.
• the top wall part 6 can be elastic in its entirety or only at its actuation area 6 '. Furthermore, for the assembly of the inner closure part 10 on the container wall 3, a continuous or subdivided locking sleeve 4 can be formed with a locking collar 5 at the free end, which can engage under the inner closure part 10.
• FIGS. 2 and 2A show a second embodiment of the invention, in which the same or similar parts as in the first embodiment have the same reference numerals and need not be described again.
• the second embodiment has an inner closure part 100 which carries the sealing pin 11 and is essentially rigid, so that the sealing pin 11 is held stationary.
• the top wall part 6 undergoes deformation not only at the actuation area 6 ′ but also in the area of the passage opening 9 under a force exerted thereon, in order to lift it out of engagement with the sealing pin 11.
