摘要:
The present invention relates to improvements in the design and construction of apparatus for dispensing microwaveable hot melt adhesives and other heat sensitive materials. The apparatus comprises a dispenser which is heated by microwaves and then used to dispense a material therefrom. The dispenser is specifically designed to convert microwave energy into heat and to transfer the heat to the material to be dispensed in a more efficient and/or safe manner.
摘要:
An apparatus for dispensing hot melt adhesive or other materials. The apparatus includes a container and an outlet. The container has a first material (the material to be dispensed) disposed therein, which changes from a solid state or a state of high viscosity to a state of low viscosity when heated above a predetermined temperature. The container also has a second material disposed therein, which is adapted to be heated above a predetermined temperature when subjected to microwaves for at least a predetermined period of time. The second material can be an inner layer of the container, can be applied to a microwave transparent sheet surrounding the first material, or can be embedded in a silicone tube surrounding the first material. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material. The first material then changes to a state of low viscosity and can be dispensed from the container through the outlet.
摘要:
A structure and a technique for heating hot melt adhesive by means of microwaves, to place the hot melt adhesive in a tacky state in which it adheres to an object. A preferred structure according to the invention comprises an article of manufacture (e.g., a wall hook) having a mass of the hot melt adhesive and a susceptor thereon. The article, with the adhesive and susceptor thereon, can be subjected to microwaves for a predetermined period of time, to place the mass of adhesive in a tacky state which enables the article to be attached to an object (e.g., a wall). A special container for the article is placed with the article into a microwave oven as a unit, and removed as a unit from the oven. The container enables the article to be safely and efficiently attached to the object.

摘要:
A shielded cover for a microwave container having upper and lower layers and a diamond-shaped metallic ring therebetween. The ring surrounds an upwardly extending multi-step truncated pyramid formed out of the center section of the upper and lower layers of the cover. The top surface of the truncated pyramid includes a series of openings to vent steam produced within the container. Microwave radiation produced by the microwave oven is reflected by the metallic ring and therefore only penetrates the cover to enter or exit the container at the corners and the center section of the cover. Microwaves are concentrated at the center section of the container and retained within the container, heating the center of the food therein proportionally more than the outer portion of the food, resulting food having a uniform and consistent temperature throughout.

A polymeric cereal container includes a first wall, a cereal chamber at least partially formed by the first wall, and a container opening at least partially defined by the first wall. A first quantity of dry cereal can be received within the cereal chamber, and a second quantity of dry cereal can be provided separately. A method can include providing and filling a polymeric cereal container with a quantity of dry cereal. A system can operate to fill a polymeric cereal container with a quantity of dry cereal.

A pizza storage container is reconfigurable to form at least one smaller pizza container, such as by folding along prefabricated fold lines. A lid support device, which may be used in combination with the reconfigurable pizza storage container or with a different storage container, serves as a cutting implement for separating pizza stored in the container.

A finishing composition for restoring the appearance of the aged, painted surface of an automobile comprises an isobutyl methacrylate resin polymer dissolved in a solvent system comprising a low boiling organic solvent and a high boiling organic solvent.
摘要:
A double-walled cooking utensil provides inner and outer metal layers which are nested together and permanently connected along peripheral flanges. Each layer provides a planar bottom portion which cooperate with each other to define a thin chamber therebetween. A sheet of reflective aluminum is positioned in such chamber and resists the transfer of radiant heat from the bottom surface of the outer layer to the bottom surface of the inner layer which constitutes the cooking surface of the utensil. The reflective sheet is embossed with a grid of ribs which extend toward the outer layer and maintain a small spacing between the portions of the reflective layer between the ribs. The utensil promotes quality baking without requiring increased baking time, and produces bakery having more uniform texture and better color.
