Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The present invention relates to socks and related items and specifically, socks that are breathable but guard against penetration of dirt from the outside inward. The sock also allows for the use of an emollient and prevents its absorption into the sock, thereby keeping it close to the skin in the area where the emollient has been applied. BACKGROUND OF THE INVENTION [0002] Various types of socks that provide protection are known in the prior art. One group of socks includes socks made to be worn with a shoe. These socks are typically made of cotton, wool or synthetic fibers, and/or blends thereof. Another group of known socks includes socks made to worn without a shoe. These socks typically have a coating that resists moisture penetration, and protects the foot from injury by sharp objects, permitting the sock to be worn outside of the house. [0003] Socks made to be worn with shoes are typically manufactured such that they provide comfort and protection to the foot of the wearer by providing a barrier between the skin of the foot and the shoe. These socks may also provide additional functions such as absorbing foot moisture, as with cotton socks, or conversely wicking moisture away from the foot, as with polypropylene socks etc. [0004] These comfort socks are disadvantageous and useless, however, for people who work or recreate in situations where dirt and debris may migrate into their shoes. In this situation, conventional socks tend to permit the movement of dirt and debris into and through the sock. When this penetration occurs, dirt can adhere to the surface of the foot and increase the possibility of cracking and scaling of the skin. Further, if the heel or sole of the foot is already dry and cracked, the dirt can penetrate into the skin, and becomes impossible to remove with normal cleansing practices. This problem is routinely faced by professionals such as landscapers and forestry workers and by non-professionals such as hikers and home-gardeners. [0005] There are numerous socks and sock-like items that can protect the foot from dirt, but are described in the prior art as having a hard and durable exterior coating and are presented as a substitute for a shoe. Examples include U.S. Pat. No. 5,617,585, issued to Fons et al, for a rubber-soled slipper sock, U.S. Pat. No. 4,276,671 issued to Florence Melton, U.S. Pat. No. 3,383,782 issued to James McGinnity and U.S. Pat. No. 266,614, issued to Catherine Douglass. The expressed intent of all these items it to protect the foot. The most common means being the coating of the sock with a thick substance, typically resin, rubber or a rubber-like derivative such as latex. In all these presentations, the expressed intent is that the sock or slipper sock, be worn without shoes. The materials used to provide protection tend to create an item that is too bulky or stiff to be worn inside a shoe or to comfortably stretch to accommodate different size feet, as would a sock. Furthermore, by virtue of the chemical properties of the substances used as the coating agents, they are not air permeable and can interrupt the normal respiration/transpiration of the epidermal cells of the foot. None of the products address the feasibility of washing the item. [0006] There are sock-like items listed in the prior art that have to do with addressing the problem of drying and cracking of the skin of the foot. These items allow for the use of an emollient while a sock-like item is being worn. There is no recommendation that they be worn with shoes or worn with shoes out of doors. None address as their goal, the preventing of penetration of dirt. [0007] A need thus exists for a sock that provides comfort, protection, tensile strength, and the durability to withstand washing, yet resists dirt and other debris from penetrating into and/or through the sock material. A need also exists that addresses the problem of the cracking of skin that can be associated with the drying effect of contact with dirt. None of the above inventions or patents is seen to suggest or claim the properties as the invention claimed herein. SUMMARY OF THE INVENTION [0008] Accordingly, it is the object of the present invention to provide a sock that resists movement of dirt or other debris from the outside inward. [0009] It is another object of the present invention to provide a sock that is sufficiently thin, pliable and comfortable to be used within a shoe. [0010] It is yet another object of the present invention to provide a sock that is a least in part coated with nitrile or a like substance. [0011] It is also the object of the present invention to provide a sock that has an interior area coated with nitrile or a like substance. [0012] It is an object of the present invention to provide a sock that has the properties that allow it to be laundered. [0013] These and related objects of the present invention are achieved by use of a nitrile coated sock as described herein. [0014] The attainment of the foregoing and related advantages and features of the invention should be more readily apparent to those skilled in the art, after review of the following more detailed description of the invention taken together with the drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0015] FIG. 1 is a side elevational view of the invention [0016] FIG. 2 is a back elevational view of the invention. [0017] FIG. 3 is an interior view of the heel area of the invention. [0018] FIG. 4 is a bottom exterior view of the invention. DETAILED DESCRIPTION [0019] Referring to FIG. 1, a sectional view of a sock 1 in accordance with the present invention is shown. Sock 1 includes a sock substrate that may be formed in whole or part of any suitable sock material, many of which are known in the art including cotton, nylon, silk, polypropylene, and others. In one preferred embodiment, substrate 1 is a blend of approximately 50% cotton-50% nylon,(though other ranges do not depart from the present invention). Continue reading about Nitrile coated sock...
