Multi-Layered Pillow Cover

Abstract

A semiconductor device includes a first layer, first and second active areas disposed on the first layer; a trench disposed between the first and second active areas, an insulating oxide that fills the trench to a level below a surface of the first and second active layers, and a nitride cap disposed on top of the insulating oxide so that the first and second active areas can be cleaned without damaging the insulating oxide. A top surface of the nitride cap in regions adjacent to the first and second active areas is aligned with a top surface of the first and second active areas, a top surface of the nitride cap in a center region of the nitride cap is stepped below the top surface of the adjacent regions, and a void is formed between the top surface regions adjacent to the first and second active areas.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a pillow sheet and more specifically to an assembly of multi-layered pillow sheets.

2. Description of Related Art

Pillow cases are used by every household for covering pillows to prevent pillows from being soiled so that pillows do not need to be cleaned frequently. But even pillow cases get soiled from sweat, drool, and oils secreted from the face or hair. Most of the time, a household won't change and wash pillow cases every day because the pillow cases need to be removed from the pillows for washing and put back on after washing. Therefore, pillow cases are used for a while until the household has time for laundry, normally during the weekend. The soiled pillow cases are not healthy to skin. Sometimes, the soiled pillowcases have an unpleasant smell. It is not pleasant to sleep on a pillow case that has hair left on it either. But to replace pillow cases and clean them every day is troublesome and tedious. Therefore, it is necessary to have a product that can conveniently provide fresh smell, clean, smooth pillow sheet everyday without causing inconvenience and trouble.

SUMMARY OF THE INVENTION

One object of the present invention is to prevent acne. The idea is to have a fresh sheet each night which is good for skin care and will help prevent the development of face pimples.

Another object of the all satin pillow cover invention is to have no wrinkles on the face from sleeping on a crumpled sheet and to prevent bed hair.

The present invention is a multi-layered pillow cover assembly which includes an attachment that wraps around the pillow. The pillow cover assembly has a plurality of fresh sheets that can be turned like the pages of a book in the morning so as to allow a fresh new sheet to be exposed for the next night's sleep experience. The sheets for oily and combination skin are made of a layer of cotton on top stitched into a polyester sheet underneath. The cotton is able to absorb oils from ones skin and the polyester prevents oils from the skin from seeping through to the next sheet. The pillow sheets for dry skin and T-zone combination skin are made of satin polyester. The new sheet every day prevents pimples and the satin helps prevent wrinkles and bed hair.

The more important features of the invention have thus been outlined in order that the more detailed description that follows may be better understood and in order that the present contribution to the art may better be appreciated. Additional features of the invention will be described hereinafter and will form the subject matter of the claims that follow.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, there is disclosed a pillow cover assembly according to one embodiment of the present invention. FIG. 1 shows the back of the pillow cover assembly 10 around a pillow 20 and it is attached to the pillow 20 using a pair of straps 12 which have fabric hook and loop fasteners 13 such as Velcro at their ends.

FIG. 2 is a front view of the pillow cover assembly 10 of the present invention. As shown in FIG. 2, the pillow cover assembly 10 has a plurality of layers of pillow sheets 11. Said layers of pillow sheets are rectangular in shape and have two short edges and two long edges. Said layers of pillow sheets are held together on one of the short edges 14 and thus said layers of pillow sheets can be flipped around the short edge 14 like a book. The layers of pillow sheets may be bound together by sewing, or by other suitable fastening means. The pillow cover assembly 10 further comprises an attachment system 12 used to attach the pillow sheets 11 to a pillow 20 or a pillow case configured to house the pillow. Preferably, there are five to seven sheets 11 that can be turned each morning so that the user has a fresh pillow sheet for his or her head each night of the week. Once the five or seven sheets have been flipped the pillow cover assembly is removed from the pillow, washed and reused. The attachment system may include a pair of straps 12 and any suitable fastening means 13 at one end of each of straps. The fastening means may include not limited to fabric hook and loop fasteners such as Velcro hook and loop.

Each layer of sheets 11 is approximately 18 inches wide and 24-31 inches long. In one embodiment, each sheet is one inch longer than the one below so there is a space that a user can have for ease of turning each used sheet 11 over to expose the new fresh pillow sheet. The sheets 11 are made of soft and smooth materials, such as polyester satin or silk satin or mulberry silk satin—a very high end silk material, so that they are good for skin care and will help prevent the development of face wrinkles or pimples. Each sheet for oily skin is made of a layer of soft cotton on the top and polyester is attached on the bottom.

FIG. 3 illustrates how the sheets 11 can be flipped upon lifting up from the pillow. The used and soiled layer of sheet 11 is lifted up and flipped over around the bound end 14 so as to expose a new and fresh layer of pillow sheet.

FIG. 4 is a stand-alone pillow covering 30 that has a bit of a frill 31 on the edge of it for decoration. Satin pillow covering 30 is used on top of the pillow sheets 10.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiments, it will be understood that the foregoing is considered as illustrative only of the principles of the invention and not intended to be exhaustive or to limit the invention to the precise forms disclosed.

Obvious modifications or variations are possible in light of the above teachings. The embodiments discussed were chosen and described to provide the best illustration of the principles of the invention and its practical application to enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are entitled.
