Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention deals with a pastry brush and more specifically, a pastry brush of uniform composition and unitary construction wherein the uniform composition includes silicone. BACKGROUND OF THE INVENTION [0002] A pastry brush is a small brush used for applying liquid substances used in the cooking and preparing of food. Some liquid subs,.ances that may be use include glazes, egg wash, oils, melted butter and lard. These substances may be applied directly to food either before or after baking. When applied to food, baked goods are usually involved, such as breads, pastries, cookies, etc. The brush can also be used for greasing cookware surfaces. For example, to apply a thin, even layer of a lubricating agent to a cookie sheet, cake, pan, or muffin tin. [0003] Normally, the best all-purpose size has a width of 1 to 11/2 inches. Pastry brushes are usually made of nylon bristles, sterilized natural bristles or goose feathers. The harder nylon bristles will last longer but may melt if accidentally touched to a hot surface. [0004] The bristles are usually clamped or glued onto a handle. With such a construction, the bristles detach easily and often end up on the food being prepared with the brush. As a result, an alternative pastry brush construction is desireable. Specifically, a unitary construction where the pastry brush is a single piece so that bristles will not become detached in use, would be best suited to fulfill this need. [0005] In addition, ordinary bristle-tipped pastry brushes are difficult to clean. It is virtually impossible to clean each and every bristle, and therefore, impossible to remove all the build up and resin that accumulates in the brush from each use. [0006] To date, no attempts have been made to provide a pastry brush of unitary construction and uniform composition. Further, no attempts have been made to provide a pastry brush that is easy to clean and resistant to the sticking and clinging nature of food and other substances. SUMMARY OF THE INVENTION [0007] A silicone pastry brush of unitary construction and uniform composition is provided. The pastry brush comprises a handle having a handle base and a back end, a brush head with a brush base and a bristle end, and a plurality of bristles. The handle base is connected to the brush base, and the plurality of bristles is disposed along the bristle end. [0008] In accordance with further aspects of a preferred embodiment of the present invention, the pastry brush is made of silicone and further comprises a hanging hole. BRIEF DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 shows a silicone pastry brush in accordance with an embodiment of the present invention. [0010] FIG. 2 shows the pastry brush of FIG. 1 from the side with the attendant forces that act upon the brush in use. [0011] FIG. 3 shows the brush head of the pastry brush in FIGS. 1 and 2. DETAILED DESCRIPTION [0012] Silicone is a term much like "plastic"--it covers a rather wide range of materials and properties. The chemistry of a particular polymer determines its characteristics, from hard and brittle varnishes, to soft and flexible rubbers. [0013] Silicones are extremely versatile and have many uses. Technically speaking, silicones are any of a group of semi-inorganic polymers based on the structural unit R2SiO, where R is an organic group, characterized by wide-range thermal stability, high lubricity, extreme water repellence, and physiological inertness and used in adhesives, lubricants, protective coatings, paints, electrical insulation, synthetic rubber, and prosthetic replacements for body parts. [0014] FIG. 1 shows a pastry brush in accordance with an embodiment of the present invention, generally indicated by reference numeral 10, for applying various liquid substances such as egg wash, melted butter or glazes to the exterior of pastry products. The brush 10 may also be used to grease cookware such as cake pans, cookie sheets or muffin tins when dipped in oil or melted shortening and applied to the surface of the cookware that will contact cooking foods. The brush 10 is preferably of unitary (single piece) construction and uniform composition consisting of silicone. That is, the brush 10 is one silicone piece having a uniform composition and construction throughout. [0015] A handle 12 has a base end 14 and a back end 16. In use, the handle 12 provides a gripping surface to hold the brush 10. A bore 18 in the back end 16 provides a means to hang the brush 10 on a hook mounted to a wall, the inside of a cabinet, pantry or closet door, or on any surface that can suitably withstand the mounting of a hook. The handle is defined along an axis 100. [0016] At the base end 14 of the handle 12, a brush head 22 is provided. The head 22 has a base end 26 and a bristle end 25. The brush head base end 26 attaches to the handle base end 14. The bristle end 25 has a number of bristles 24 extending therefrom, along the width of the end 25 and outwardly, lengthwise from the brush 10. The bristles 24, brush head 22, and handle 12 are all of a uniform composition. The center line of the brush head 22 is aligned with the axis 100. [0017] A reinforcing, or strengthening rib 20 runs along the length of the handle 12 and provides substantially rigid resistance in the handle to prevent bending of the brush during brushing operation as force is applied to the bristles 24 and brush head 22. The rib 20 preferably runs virtually the entire length of the handle 12 from the hanging hole, or bore 18, to the base end 14. [0018] The brush 10 has an overall length L, approximately 9-13% of which includes the brush head 22, with the remainder being the handle. In preferred embodiments, the handle 12 and brush head 22 are both made of the same material. [0019] FIG. 2 shows a side view of the brush 10 and the forces applied to the brush 10 when used. In use, the brush 10 is held around the handle 12 and pulled horizontally in the direction indicated by arrow 200 along a surface to be greased, glazed, oiled, etc. of a pastry product or piece of cookware (not shown). At the same time, the brush 10 is pushed downwardly to ensure even and constant contact between the bristles 24 and the pastry product. This downward application of force pushes the bristles upwardly, in the direction of arrow 202. Continue reading about Silicone pastry brush...
