Abstract
Comprises exposing one portion of each of the batteries to a solution of denatonium benzoate, the solution having a concentration in the range of 0.25% to 2.5% weight by volume, and drying the batteries so as to form a dried coating of denatonium benzoate on the batteries. In a preferred embodiment one side of each of the batteries is exposed to the denatonium benzoate solution and the batteries are transferred to a drying chamber after exposure to the solution of denatonium benzoate with the air temperature in the drying chamber being elevated to a temperature in the range 100 to 150 DEG C.
Description
1 1 2254807 A METHOD FOR COATING BATTERIES WITH A BITTER TASTING SUBSTANCE
The present invention relates to a method for coating batteries, particularly but not exclusively zinc/air batteries, with a bitter tasting substance.
Denatonium benzoate is a known very bitter tasting substance sold under the trade mark BITREX. BITREX may be used to coat small non-metallic items. However, it has been generally accepted that BITREX could not be used in coating metal objects because the compound would not adhere directly onto metal.
It is an object of the invention to provide a method of coating metal objects such as batteries.
The present invention provides a method for coating one or more batteries with a bitter tasting substance comprising the steps of: exposing a portion of each of the one or more batteries to a solution of denatonium benzoate, the solution having a concentration in the range of 0.25% to 2. 5% weight by volume, and drying said batteries so as to form a dried coating of denatonium benzoate on the one or more batteries.
Thus, the present invention provides a method for coating batteries having a metal outer shell with a bitter tasting substance so as to deter the swallowing of the batteries by children and to prevent the ingestion of harmful chemicals contained in the batteries.
Preferably, the solution of denatonium benzoate has a concentration of 1. 2% weight by volume and only one surface of the batteries is exposed to the denatonium benzoate solution. The batteries may be dried at room temperature.
t In a further aspect, the present invention provides a battery having a coating on a portion of the battery of denatonium benzoate applied in the method described above.
Preferably, the denatonium benzoate coating has a concentration of 1Oppm and the battery is a zinc/air battery.
For a better understanding of the invention and to show how the same may be carried into effect reference is now made to the following specific example.
EXAMPLE 1
CLEANING Batteries having a metallic casing such as button cells (including silver oxide, mercuric oxide, alkaline and zinc/air batteries) are cleansed by wiping a portion of each battery such as an upper surface of each of the batteries with an absorbent cloth or pad which has been pre-soaked in a solution of deionised water and detergent.
The solution is as follows:
1 of deionised water 1 1 of detergent, for example the detergent sold under the trade mark MICRO CLEANSE ml of detergent, for example the detergent sold under the trade mark TEEPOL Solution temperature 60 0 C.
FIRST RINSE The batteries are then rinsed by wiping the same surface of each of the batteries with a second absorbent cloth or pad which has been pre-soaked in deionised water.
k TREATMENT WITH BITREX A third absorbent cloth or pad is pre-soaked in a solution of Bitrex which is made from a 2.5% Bitrex solution diluted using deionised water. The solution is at room temperature and has a concentration in the range of 0.25% to 2.5% weight by volume and preferably 1.2% weight by volume. The third absorbent cloth or pad is wiped over the same one surface of each of the batteries. Thereafter, the batteries are stored in a drying chamber. The air temperature in the drying chamber may be at room temperature or alternatively may be elevated to a temperature in the range 100 to 150 0 c and preferably 120 0 C. When an elevated air temperature is used the batteries remain in the drying chamber for between 1 and 20 seconds. The batteries may be placed on a conveyor to be continuously conveyed through the drying chamber or oven.
When dry, a coating of between 2.0 and 25 ppm of Bitrex is formed on the one surface of each of the batteries.
Instead of using an absorbent cloth or pad the one surface of each of the batteries may be exposed to the Bitrex solution by spraying the solution onto the batteries. Thereafter, the batteries may be transferred to the drying chamber and the dried coating formed as described above.
By applying the cleansing and Bitrex solution to only one side of the batteries zinc/air button cell batteries, which have a vent in the battery casing, can be coated with the Bitrex solution on the anode and crimp region of the cell without damage to the battery.
