Definitions
- the invention relates to a reverse rotation lock for a rotary closure system having a first closure element which is rotatably arranged opposite a second closure element and halterbar in at least one oriented position, comprising at least one latching element that is fixed to one of the closure elements and thus corresponds to at least one associated latching cam, in that the first closure element is detachably held in the at least one oriented position relative to the second closure element.
- screw caps for containers or volumes of various kinds are used in order to close these against the contents largely or completely tight.
- screw caps are formed as a rotary closure systems consisting of a flange and a screw cap and are designed as resealable systems.
- the closure or screw caps are often designed to be removable after opening the closure system.
- the flange usually has a shoulder portion which is intended to be fixed to the actual container.
- a container may be integrally formed with the flange.
- the container material and the flange material are the same and the flange is an integral part of the container.
- an area adjoining the shoulder of the flange is designed as a pouring opening for the container interior and provided with a thread which corresponds with the screw cap such that the pouring opening can be closed by the screw cap by rotational movements of the screw cap.
- the screw cap is a first closure element in this system. Due to the fact that threads can not usually assume a sealing function, an axial force generated in the thread and by a rotational movement is used to press the end of the screw cap against the front end of the pouring opening of the flange and thereby to achieve a seal.
- the thread can be designed as external thread either on the flange or on the screw cap.
- the screw cap it is almost always desirable for the screw cap to reliably close the container under all storage, transport and handling conditions. In general, it is required that the closure function is hermetically sealed. This also applies to situations in which the substance accommodates different substances with free-flowing or pourable properties, or at least does not preclude an internal pressure of the container which is above the atmospheric pressure.
- the materials of the closure system are coordinated so that a sufficiently high static friction and there is a breakaway torque of the screw closure elements consisting of the thread at the pouring opening and the thread on the closure cap.
- the thread design is realized in such a way that both self-locking and sufficient closure forces are achieved.
- the thread pitch is a primary influencing factor for this.
- a further situation which opposes the reliable closure function can be present if the closure cap is rotated in the opening direction by torques acting from outside and this is not the result of a deliberate or purposeful handling process. Likewise, reverse rotation may be undesirable to prevent unlawful product removal.
- anti-rotation locks are used in rotary closure systems in order to maintain the rotational closure position of the closure cap and the shutter forces generated thereby also in situations in which external acting torques in the opening direction, which are not the result of a conscious or targeted handling operation.
- Known pollutantsréen are often formed by locking elements and locking cams, which are defined in a corresponding manner in each case on a closure system element. It is customary to arrange these anti-rotation locks adjacent to the thread and directly on the usually cylindrical pour opening or the cap as an integral part. This one-piece design supports injection molding, especially when using plastic materials. Locks equipped with such a reverse lock are only limited in terms of machine operation or do not sufficiently prevent unintentional unscrewing.
- the contact points or fixing areas of the integral latching elements on the respective closure element are, for example, trapezoidal geometric Design, which leads to a certain inelasticity.
- the latching element has to be partially elastically-plastically deformed relative to the latching cam in order to realize the opening or closing movement.
- the required opening and closing torques, which must act on the cap are very high and difficult to adjust.
- this object is achieved by at least one locking element, the contact point or fixing region is configured on the respective closure element such that an elastic fixing is supported and that the locking element is swingable due to the elastic fixing.
- the teaching of the invention recognizes that due to an elastic fixing of the at least one locking element by a suitable geometric or material engineering design of the contact point or the Festlegungs Kunststoffes on the respective closure element, the locking element is swingable.
- the partially elastic-plastic deformation of the locking element and thus also the wear can be reduced.
- the force required for the opening and closing movements can be influenced by influencing the Setting the degree of elasticity, on the other hand, a reduction of the required opening and closing forces is counteracted by the wear-reduced interaction of locking element and locking cams.
- the determination of the locking element can be made such that in addition in the end position, i. in the closed position of the first closure element, the swingable locking element snaps behind the locking cam.
- the snap-in process can be designed such that an acoustic and / or haptic feedback is sent to the user.
- the acoustic feedback can be realized by a click sound.
- the haptic feedback can be realized by an increased closure force along a part of the rotational movement.
- the elastic fixing of the at least one latching element on the respective closure element by a suitable geometric design of the contact point or the Festlegungs Kunststoffes is alternatively or cumulatively realized in various embodiments that the Festlegungs Kunststoff or the contact point is formed by a radially extending to the closure element web.
- the web can be formed with a relative to the locking element reduced cross-section, which supports an elastic component behavior.
- the outer contour of the web between the respective closure element and the locking element can be configured radii similar, so that the local elasticity of the web is supported by a targeted inner stress concentration due to notch effect.
- the elastic fixing of the at least one latching element on the respective closure element by a suitable choice of material or a material combination of the contact point or the Festlegungs Kunststoffes is alternatively or cumulatively realized in various embodiments that the Festlegungs Kunststoff or the contact point at least partially by an elastic material such as plastic, For example, PE, PP, PET, PLA, PEF, rubber or a spring steel is formed.
- an elastic material such as plastic, For example, PE, PP, PET, PLA, PEF, rubber or a spring steel is formed.
- the locking element is made of a different material than the closure element is formed.
- At least one of the geometric configurations as well as at least one of the proposed material specification or even a combination of these properties can be used.
- the invention recognizes that due to an asymmetrical design or an asymmetrical fixing of the at least one latching element on the respective closure element, different high forces for opening or closing the screw closure are both realizable and adjustable. Can be adjusted, the respective forces for opening and closing and by bevels on the locking element in the respective direction of movement.
- Figure 1 is a plan view of a section of the at least one locking element (1 1) on the screw cap (10) according to a known prior art, wherein the locking element is arranged directly on the threaded cylinder and
- Figure 2 is a perspective view, a plan view and a detail A of the closure system (1) according to the present invention, wherein the base member of the thread-carrying cylinder is arranged separately.
- Figure 1 shows a plan view of a section of the at least one locking element (1 1) on the screw cap (10).
