Abstract

Childproof safety cap having two opposite bead-like threads on its inner wall. Each thread has a widened end region, a stop surface thus being formed. The associated bottle has two opposite groove-like threads on a connecting piece of said bottle, each of which threads has a widened region in the end region, an undercut thus being formed in the groove by the widened region. When the safety cap is screwed on, the stop surfaces on the two bead-like threads hook in behind the undercuts on the groove-like threads. The stop surfaces can be released from each other only if the safety cap is pressed down toward the bottle onto the connecting-piece neck. Connecting-piece neck forms a slipping surface that conically expands downwards. The safety cap can then be unscrewed while simultaneously being rotated.

Claims

1. A child-resistant protective cap having an associated container or bottle for liquid or pasty media, equipped with a closure or an application system for said media, characterized in that the protective cap (1) and the bottle (9) are each equipped with at least one thread (6, 15), which engage each other by one thread (6) being outwardly protrudingly shaped and the other thread (15) being recessed in a groove-like manner, and wherein at the lower end of the thread (6) on the protective cap (1) or bottle (9) there is configured on the protruding thread (6) a widened region (7) which is screwable in the groove-like thread (15) along the same and at its back end forms a stop face (8), and wherein said widened region (7), in the end position of screwing on the protective cap (1), engages a wider region (17) in the groove-shaped thread (15) on the bottle (5) or protective cap (1), which wider region (17) forms an undercut (18), so that the stop face (8) on the protruding thread catches behind the undercut (18), and the stop face (8) is squeezable under the undercut (18) only by pressing the protective cap (1) toward the container or the bottle (9) with slight elastic deformation of its walling in the mouth region, and the protective cap is hereinafter unscrewable upon simultaneous rotation.

2. The child-resistant protective cap having an associated container or bottle for liquid or pasty media according to claim 1, characterized in that the protective cap (1) has two mutually opposing bead-like threads (6) on its inner wall, each with a widened end region (7), so that a stop face (8) is formed there in each case, and the associated bottle (9) has two groove-like, mutually opposing threads (15) on its spout (12), and each has a widened region (17) in the end region, so that an undercut (18) is formed by the latter, so that upon screwing the protective cap (1) on, the stop faces (8) on the two bead-like threads (6) catch behind the undercuts (18) on the groove-like threads (15), and the stop faces (8) are squeezable under the undercuts (18) only by pressing the protective cap (1) toward the container or the bottle (9) with elastic deformation of the walling of the protective cap mouth at the spout neck (11), which for this purpose forms a downwardly flaring slide-off surface, and hereinafter the protective cap (1) is unscrewable upon simultaneous rotation.

3. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of the preceding claims, characterized in that the protective cap (1) forms on the underside of its end face a sleeve (15) which is fittable over the mouth (22) of the application system so that an evaporation protection is formed and, upon unscrewing, the protective cap (1) is screwable around said mouth (22), which in so doing acts as an axis.

4. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of the preceding claims, characterized in that at the lower edge of the protective cap (1) a tamper-evident band (2) is molded over one or more thin places or over one or more predetermined breaking points, and at one place in the circumferential direction said tamper-evident band (2) is interrupted and has a pull-off flap (3).

5. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of the preceding claims, characterized in that the neck (11) of the bottle spout (12) flares downwardly, and that it is of pentagonal shape as seen from above so that its faces lying between the corners form elastically yielding slide-off surfaces for the lower edge of the screwed-on protective cap (1).

6. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of the preceding claims, characterized in that the protective cap (1) is equipped with indentations (4) or bulges on its outer side for guaranteeing better haptics for screwing the protective cap (1).

7. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of the preceding claims, characterized in that the protective cap (1) covers and encloses the entire application system (19) in the form of a spray pump mounted onto the bottle.

8. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout having an application system in the form of a pump, a dropper or a closure according to any of claims 1 to 6, characterized in that the protective cap (1) covers and encloses the entire application system (19) in the form of a dropper mounted onto the bottle.

9. The child-resistant protective cap having an associated container or bottle for liquid or pasty media, for mounting onto an associated bottle spout with application system in the form of a pump, a dropper or a closure according to any of claims 1 to 6, characterized in that the protective cap (1) covers and encloses the entire application system (19) in the form of a closure.
