Closure Cap For A Detergent Bottle

Abstract

A closure cap for a detergent bottle, the closure cap including at least one cap wall having a plurality of surface elements spaced apart from one another. The surface elements each have a circumferential edge, starting from which the particular surface element extends from a datum plane of the cap wall, and which surrounds a base of the surface element located in the datum plane of the cap wall. In order to form a smooth transition from the datum plane that does not have a notch effect, a radius of curvature is provided at the circumferential edge that is larger than the largest longitudinal extent of the base of the surface element.

Description

FIELD OF THE INVENTION[0001]The invention relates to a closure cap for a detergent bottle, the closure cap comprising at least one cap wall having a plurality of surface elements spaced apart from one another.BACKGROUND OF THE INVENTION[0002]A closure cap of this kind is known, for example, from U.S. D597,844 S (U.S. patent Design). The surface elements are dots or protuberances, each of which has a circumferential edge in the form of a circle, starting from which the particular dot extends from a datum plane of the cap wall, and which surrounds a circular base located in the datum plane of the cap wall.[0003]It is known that the surface elements on the cap wall are used to pretreat stains on a laundry item to be cleaned. Several drops of the detergent from the detergent bottle are applied to the stain and then rubbed into the material of the laundry item by means of the closure cap having the surface elements or portions of which the surface is rough. It is known from EP 2 867 131 ...

AI Technical Summary

Benefits of technology

The invention is a closure cap for a detergent bottle that has improved strength and tightness compared to existing caps. It also has a rough surface that provides better grip and helps to disperse forces during impact. This design prevents a notch effect and allows the cap to withstand higher drop heights during the drop test. The closure cap can effectively pretreat stains and is easy to open and close even in adverse environments. The surface elements have a relatively small size and a smooth transition, which helps to disperse the impact forces and increase the surface roughness.

Problems solved by technology

When shipping a bottle via parcel services, it can no longer be guaranteed that the detergent bottle will stay upright at all times. Furthermore, it cannot be ruled out that there may be relatively great forces or impacts acting on the bottle and the closure cap, at different angles, when the bottle is being transported.

In the worst case, excessive forces or impacts on the closure cap can result in the closure cap breaking, or the closure cap no longer being able to reliably help seal the detergent bottle.
