Abstract
A self-cooling, portable liquid container is disclosed in the form of a bottle with an indent on any surface, preferably the bottom, into which a cooling mechanism can be inserted.
The cooling mechanism consists of an encapsulated area containing two or more reactants separated by a non-permeable membrane, and one or more appendages which will serve to puncture the non-permeable membrane, allowing the reactants to mix and the endothermic reaction to occur. The reactant capsule is sealed at one end by a flexible material (A) that surrounds the joint of the capsule. Another flexible material (B) joins flexible material (A) and provides additional pressure such that the non-permeable membrane can be pushed up to the appendages for puncture. Flexible material (B) also provides friction to hold the cooling mechanism in the indent in the container. A
moldable material provides the base upon which the cooling mechanism rests and may be turned and pushed up to rupture the non-permeable membrane, resulting in mixing of the reactants.

Description
Field of Invention The present invention generally involves instant cooling of portable drinking liquid. More particularly, the invention involves a cooling mechanism that can be inserted by vaxious 30 means into a water bottle or other liquid container and be activated to undergo an endothermic reaction that will instantly cool any liquid inside the container.
The resulting container and cooling mechanism combination allows for a portable liquid container that can be made cold without the addition of ice or the use of a refrigerator.
35 Background Art This new version of a liquid container combines previous inventions such as a typical liquid bottle and the concept of the disposable cold compress (CA 2426516). A
bottle cap with push-pull closure (CA 2037728) may be used as the drinking spout, but any lid mechanism will suffice. The concept of the cold compress patent (CA 2426516) is 40 applied to the cooling mechanism, but modified in terms of structure and contained reactants. Other modifications may be added such as using a moldable material for the bottle that provides insulation to maintain the cold temperature of the liquid after the cooling mechanism has been activated.
45 Conventional drinking bottles sold in stores are rarely insulated resulting in warming of the liquid after it has been purchased and removed from the refrigerator.
Furthermore, athletes attending sporting events must bring their liquid to games in big coolers with lots of ice to keep them cool until the desired drinking time, which can be an inconvenience.
Our invention combines the aforementioned patents along with novel ideas to create a 50 liquid bottle or container that can be activated any time after purchase to instantly cool the liquid inside.
An object of the invention is to provide the public with a way of having a cold drink without adding ice or using a refrigerator.
SS
It is a fiuther object of the invention to provide a liquid container into which a cooling device can be inserted or removed, if cooling the liquid is not desired.
Summyrv of the Invention 60 The invented cooling mechanism is designed for use with the invented liquid container, which contains one or more indentations (preferably on the bottom of the liquid container) into which the invented cooling mechanism can be inserted. The two components should be sold as a unit, appearing as a regular liquid bottle with the exception of the base, which can be turned and pushed up slightly towards the top of the 65 liquid bottle in order to activate the cooling mechanism. The liquid container is in turn designed to incorporate the cooling mechanism, whether it is at the bottom of the liquid container, through the spout, or on any other surface.
The liquid container is formed from any moldable material, preferably with insulating 70 capacity that should be thinner around the indentation into which the cooling device is to be inserted, allowing for the liquid to be cooled faster. This indent is continuous with the exterior of the liquid container so as to prevent any contamination of the drinking liquid by the cooling reactants. The indent may be any width and length although it should be long enough to draw heat evenly from all areas of the liquid container, and not too wide 75 so as to maximize the amount of liquid the container can hold.
The cooling mechanism may be activated by a twist and push on the base, made of any moldable material. The dual twist and push actions of the activating mechanism are a safety precaution that will ensure the liquid bottle will not accidentally be activated to 80 cool.
The area encapsulating the two reactants is a thin envelope wherein the two reactants of predetermined amounts are separated by a non-permeable membrane. When the non-permeable membrane is punctured, an endothermic reaction draws heat from the liquid in 85 the container, cooling it to a favorable temperature. A dye may be placed in either or both reactant vessels in such a way that the consumer can see when the reaction has taken place.
Description of Fires Figure 1: Shows complete liquid cooling apparatus Figure 2(a): Displays modified container for liquid Figure 2(b): Illustrates cooling device Detailed desgriotion and M~~ mode of carrying ont ~hedi gvention 95 Referring to Fig. 1, the cooling device (Fig. 1, B) is shown in combination with a container (Fig. 1, A). The container is usually a conventional plastic water bottle with a small opening for capping and a closed base (Fig. 2b, I~ with one invagination (Fig. 2a, B) into which the cooling device can be inserted, and through which contact between the encapsulated liquid and the cooling device is possible.
The cooling device and the container are presented separately in Figs. 2a and 2b. The cooling device is composed of a plastic capsule (Fig. 2b, C) containing reactants A and B
separated by a non-permeable membrane, which can result in an endothermic reaction upon mixing. A flexible material surrounding the joint of the capsule, so, seals the 105 capsule such that leakage of contained reactants (Fig. Zb, E) is prevented. The flexible material to which the capsule is sealed to is mounted on a base, such that the base's radius is larger than the radius of the bottom of the container and enables the insertion of the capsule into the invagination of the container.
110 For optimal cooling of the liquid in the container, the endothermic reaction involves the addition of purified urea powder to water in the ratio of 3g-15g of urea (reactant A) to l0ml of water (reactant B) for every 100 ml of contained liquid.
A colorant/dye can be added to one or more reactam such as the urea powder so that the 115 colors of the two reactants are distinct. Upon mixing, the colorant will also stain: the other reactants in the capsule, thus acting as an indicator to allow the detection of any mixing occurring by accident.
The insertion and capping of the cooling device to the container will induce enough 120 pressure on the flexible material such that compression of the flexible material will push the membrane bag containing urea towards the appendages, at the same time, the turning mechanism for capping the cooling device onto the container will assist the rupturing of the membrane by the appendages, thus release the content in the membrane bag.
125 The radius of the invagination on the container should be slightly larger than the radium of the capsule but still allow close contact between the two layers of plastic, thus enable the fast conduction. The length of the invagination should be slightly shorter than the capsule such that the limitation of physical space due to capsule insertion will aid the compression of the flexible material.
The flexible material should be adaptable so that significant compression and twisting of this material allows for the rupture of the membrane bag by the appendages.
