Abstract: A plastic bottle, in particular a toilet cleanser bottle, has a bottle container, preferably formed by blow-molding, with a bottle neck and an angled attachment. The attachment is snapped onto the bottle neck in a direction of placement. The bottle neck has a first snap connection element and the attachment has a second snap connection element. In order to ensure a defined angular orientation between the angled attachment and the bottle container, an anti-rotation lock is formed between the attachment and the bottle neck, in particular between the two snap connection elements. To this end, preferably the snap connection elements engage positively with one another by way of toothings. Alternatively, an elevation having recesses is formed on a bottle shoulder for ensuring the anti-rotation lock.

Abstract: A dosing cap is configured for fitting on a dosing bottle and has a dosing channel which extends in a longitudinal direction and which has, at one end, an outlet opening for a liquid that is to be dosed. The dosing channel contains a first dosing portion, which tapers in the longitudinal direction to a dosing diameter, wherein the dosing diameter is in the range from 0.2 mm to 1.2 mm. Moreover, the dosing channel contains a second dosing portion, which adjoins the first dosing portion in the longitudinal direction to form a first step and which has a diameter greater than the dosing diameter.

Abstract: A closure element contains a cap element for closing a bottle. The cap element has a first bottleneck section that is configured for attachment to a bottleneck of the bottle. In addition, at least one adapter is provided for placement between the cap element and the bottle. The adapter has a second bottleneck connection, which is similar to the first bottleneck connection, and a bottleneck piece onto which the cap element can be placed with its first bottleneck connection. The bottleneck connections are preferably configured as snap closures. Due to the two-part construction of the closure element with the cap element and the adapter a multitude of variants is made possible for the closure element in an inexpensive manner.
