Abstract

A device for compartmentalizing liquids. More particularly, the present disclosure relates to an overspill-protection compartmentalizing device to be used in conjunction with a liquid container. The container may be a glass, a beaker, a cup or any other device for containing a liquid of any kind. The compartmentalizing device uncoils so as to take up the width of the container in order to divide the liquid present inside the container and to avoid spillages and splashing in the event of shaking caused by a person or an environment. It notably allows persons suffering from tremors to avoid being stigmatized by having a discreet device.

Description

FIELD OF THE INVENTION

The present invention relates to the field of liquid compartments. More particularly, the present invention relates to an anti-overflow compartmentalization device to be used in conjunction with a liquid container.

STATE OF THE ART

Liquid containers are devices well known to the public which allows them to transport their drinks with them, whether at work or at home or in various means of transport.
However, a container filled with a liquid, such as a glass of water or a cup of coffee, represents a danger for its user, especially if he has tremors or if he is in a moving vehicle, boat, car, plane, bicycle in particular. There is a risk of burns and user discomfort as well as possible cleaning costs.
There exist already-known anti-spill and anti-splash systems which make it possible to overcome the problems presented above. They are of two types: liquid compartmenting devices of the insert type, used inside containers intended to receive liquid and in direct contact with the liquid, and anti-spill and anti-splash systems external to containers intended for receive liquid, which are not in direct contact with the liquid.
Liquid compartmenting devices, which generally have an anti-spill and anti-splash function, are generally rigid in nature, not adaptable to containers of different shapes and sizes, and their cleaning is generally complex. External anti-spill and anti-splash devices are devices which act outside the container, without contact with the liquid, either by the fact that they are mechanically fixed to said container or by the fact that they are integral of the container.
These external devices have the disadvantage of having often a strong visual impact on the user, in particular in that they hide the contents of the container (lids, for example) and which could prove to be stigmatizing for an impaired user (lid beak, straw, pliers for example).
The present invention overcomes the difficulties presented above by presenting a highly effective anti-spill and anti-splash insert, adaptable to any type of container intended to receive a liquid, which has a self-deploying function, and which is aesthetically neutral with a transparent texture which is non-stigmatizing for the user.
