- liquids and / or free-flowing and pourable substances are liquids and / or free-flowing and pourable substances.
- the liquid product should be issued as characterized by its fluidity and as such. Examples are drinks of all kinds such as water, fruit juice, tea, wine or household products such as dishwashing detergent, liquid detergent, flowable creams, showering, etc.
- containers are provided for storage, depending on the requirement, for example cardboard packagings, glass containers, plastic bottles, tubular bags or other containers which provide volume.
- reclosable closures, plugs or pouring aids are often used, which must meet a variety of requirements.
- suitability for cost-effective mass production and perfect tightness in the closed state further criteria can be met.
- the one-handed operation of a closure may be required.
- the closure is often designed to aid in product removal by attaching it to the mouth of a user or athlete.
- opening and closing of the container can be done only with the help of a hand and the mouth.
- screw caps are known, which are usually formed from a fixable on the container flange with a nozzle. This usually one-piece executed first component of a pouring aid is based on a plastic.
- the flange shoulder often has effective surfaces for connection and attachment to the container.
- the nozzle is often formed as a short piece of pipe or central body and has an internal or external thread, which corresponds to the second spouting aid in the form of a closure cap.
- screw caps are often sealed via the frontal, concentric annular surface of the nozzle in connection with the bottom of the closure cap.
- the tightening torque of the thread pairing must be in a corresponding range.
- the pouring aid which is designed as a screw cap with a nozzle, closure cap and threads corresponding between these components, requires a complicated introduction of a rotational movement in order to move this closure type between the open position and the closed position.
- the kinematics of motion consist of an axial and preferably linear movement involving a first movable movement.
- closing part against a second closure part performs to be able to be moved between the open position and the closed position can.
- Structurally provided for this purpose is usually at least one axially aligned groove in one of the closure parts, while the other closure part a spring or a projection comparable to a sliding block guided in the at least one groove provides.
- an axial mobility of a closure member is limited by stops, so although there is mobility between the open position and the closed position, but not beyond that, one can be separated from the other closure part.
- the object is to provide a closure assembly in which the closure is axially movable between a closed position and an open dispensing position without the need for any particular angular alignment between the mutually displaceable parts and which provides an internal seal in the container neck which in both Closure positions is effective.

- the assembly and separation of the closure parts to each other is supported by the at least substantial absence of undercuts in preferential axial closure direction on at least one of the closure parts or its active surfaces or on both surface pairings.

- the inventive construction of the closure makes it possible in particular to realize an opening of the valve by rotating the upper closure part relative to the lower closure part.
- a lifting movement takes place, as is achieved, for example, in push-pull closures by pulling on the upper closure part.
- a closing of the valve can then take place in accordance with a known from push-pull closure operation sequence by pushing back of the upper valve member in a longitudinal direction without additionally required rotational movement.
- the inventive and largely undercut-free active surface pairings of the closure parts are arranged and designed such that
