Abstract

A method of warming food dispensable from an aerosol dispenser. The aerosol dispenser is made from materials which can go into a single recycling stream having a single class of materials, as defined by the Society of the Plastics Industry, and particularly may exclusively comprise Class 1 materials suitable for eating in a microwave oven. Consumer products, such as food, contained in the aerosol dispenser may be heated in a microwave oven prior to dispensing. Upon dispensing, food retains residual heat, and is suitable for eating or further cooking. Other heated products in the aerosol dispenser may be comfortably applied to the skin, used as air freshener, used for cleaning, etc. The aerosol dispenser may have indicia indicating the aerosol dispenser is suitable for microwave heating. The aerosol dispenser can have indicia indicating the aerosol dispenser is suitable for heating in a microwave oven. The indicia may be thermochromic, indicating when a desired temperature has been reached. The aerosol dispenser can have a safety valve, to safely relieve product and/or propellant pressure upon overpressurization in a microwave oven. The safety valve may be single use or reusable.

First claim

What is claimed is:

1. A microwavable aerosol dispenser comprising:
an outer container having a closed end bottom at a first end and an open neck at a second end and defining an outer container volume therein;
a product disposed in said outer container;
a product delivery device for providing a flow path to ambient for the product disposed in the outer container, wherein the product delivery device is selected from the group consisting of: a collapsible bag, a dip tube, a piston, and combinations thereof;
a dispensing valve assembly for selectively dispensing the product from the aerosol dispenser;
propellant disposed within the outer container and pressurizing the product to a gage pressure greater than ambient, to provide for selective delivery of the product from the aerosol dispenser,
wherein the outer container, the product delivery device, and the dispensing valve assembly are polymeric;
differential temperature indicia associated with the aerosol dispenser, one or more indicia indicating the aerosol dispenser is suitable for heating in a microwave oven, wherein the one or more indicia comprises thermochromic indicia, wherein the thermochromic indicia is disposed in a band that circumscribes the aerosol dispenser, and wherein the thermochromic indicia is displayed on an internet where the thermochromic indicia is viewed on a phone or tablet or computer and is configured to indicate when to stop heating the aerosol dispenser in the microwave.

2. The microwavable aerosol dispenser according to claim 1 wherein the one or more indicia comprises instructions for heating the aerosol dispenser in the microwave oven.

3. The microwavable aerosol dispenser according to claim 2 wherein the thermochromic indicia is disposed on the outer container.

4. The microwavable aerosol dispenser according to claim 1 wherein the product is disposed in the bag, the propellant is disposed between the bag and the outer container.

5. The microwavable aerosol dispenser according to claim 1 wherein the product is disposed in the bag, the propellant is disposed between the bag and the outer container and wherein the thermochromic indicia is disposed on the bag.

6. The microwavable aerosol dispenser according to claim 1 wherein the product and the propellant are intermixed.

7. The microwavable aerosol dispenser according to claim 1 , the outer container having a diameter less than or equal to 7.62 cm and a volume ranging from 118 cc to 1000 cc and the gage pressure is less than 965 kPA @ 50 C.

8. The microwavable aerosol dispenser according to claim 1 , further comprising a second indicia, the second indicia indicating the aerosol dispenser is entirely class 1 recyclable as defined by the Society of the Plastics Industry.

9. The microwavable aerosol dispenser according to claim 1 , wherein each of the outer container, dispensing valve assembly, and product delivery device is selected from the group consisting essentially of class 1 recyclable materials as defined by the Society of the Plastics Industry.

10. The microwavable aerosol dispenser according to claim 1 further comprising a disposable cap, and wherein the thermochromic indicia is disposed on the disposable cap.
