This invention relates to disposable covers placed on handheld remote control devices serving as barriers to microbes and other environmental contaminants. The flexible and transparent pouch-like covers are comprised of biodegradable materials and are inexpensive to manufacture.
It is well known that door knobs, keyboards, pens, television remote controls and any object used by the hotel guest may contain millions of germs. Pathogens thrive on smooth or moist surfaces and viruses may survive more than four days. Upon entering the hotel room a client may contact the doorknob once or twice, while handling the television remote control offers repeated opportunities for transmission of germs during the hotel stay. As global travel increases, new strains of viruses and pathogens may be imported or exported from one country to another via humans.
In hospital rooms, pathogens on objects contacted by the patient may become agents of infection. If a patient in a weakened condition due to illness or postsurgical recovery, exposure to additional microbes may introduce a secondary infection with significant implications. Pathogens present more serious consequences and may result in the premature death of a patient. A patient may enter a hospital for a routine or elective surgery, but end up gravely ill due to contact with a pathogen contacted in the hospital room.
Surfaces having a higher population of pathogens include remote or handheld controls for television, bed adjustment, patient controlled analgesia, and sleep apnea controls. By using a disposable cover, contamination risk may be reduced or eliminated. Historically, cleansers or spray cleaners were used to kill bacteria on handheld remote controls. They consist of sprays in a canister as shown in the patent by Veltman et al, U.S. Pat. No. 6,969,698, or cloths with solution on them. Spraying a remote control daily will compromise electronic function as cleaning agents seep into controls through the gaps around the control buttons. The hospitality or hotel cleaning crew easily overlooks the task of daily cleaning the remote control. Furthermore, there is no way to prove the controls have been sanitized.
Early prior art in this field reveals the patenting of remote control and handset covers for the purpose of protecting the electronic components from shock damage, liquids or other environmental contaminants Examples of patents associated with physical protective enclosures for an electronic device or handset are numerous. U.S. Pat. Nos. 4,836,256; 4,762,227; 5,388,691; 5,316,141; 6,471,056; 5,092,459 and 5,499,713 represent prior art in which protective qualities of the cover are described, including case-like features and foam-lined structures.
Prior art also emphasizes the “barrier” or “shield” like qualities of the cover. Contaminants comprising human biological waste, pathogens in the environment, or other infectious agents are prevented from crossing the bather provided by the cover from the control device to the hand holding the control device. Since the primary scope of the present invention is to prevent human exposure from contaminants, a closer look at the attributes of the present invention will reveal improvements and qualities not previously described in the art including a unique means of delivery and materials which are ecologically compatible.
While reviewing prior art which teach the protective qualities of the covers, the Hodges U.S. Pat. No. 7,290,654 presents a seamless molded unitary barrier which is impregnated with an anti-bacterial compound. In comparing the present invention with that of Hodges, the present invention does not require molds to be fabricated or the use of injection molding equipment, which results in lower start-up manufacturing costs.
The Clark et al U.S. Pat. No. 7,011,213 relates a “protective shield for a patient control device” which is a disposable shield to sheath a patient control device, in which there is a sealing clamp placed around the shield and cable to the nurse call device. The paper backing is used to stabilize the shield during the insertion of the nurse call device. The present invention employs a simple manufacturing process and likely less cost in materials when compared to the protective shield and clamp described by Clark et al. in U.S. Pat. No. 7,011,213. There is also less waste in the present invention as the covers do not require individual packaging.
Similarly, the Gammons U.S. Pat. No. 7,147,105 describes a sheath with a scalloped shoulder area which permits expansibility to accommodate controls with rotary dials, and is fabricated on a paper carrier, with one sheath mounted on each carrier within a storage package. Compared to the present invention, it is likely to be more expensive in the manufacturing process and is designed for a specific shape of remote control. The carrier papers are required for the Gammons patent but not in the present invention.
The Trujillo U.S. Pat. No. 6,050,407 exhibits a protective “sheath” which wraps snugly around the remote control, and is self-adhered. The additional open end does not provide as much coverage when compared to the present invention.
A variation is an “envelope” utilizing “gripper pads” which are of durable and reliable construction as described by the Huffer U.S. Pat. No. 5,499,713. The present invention has a simpler construction and does not utilize gripper pads.
The Goldberg U.S. Pat. No. 6,817,470 relates a flexible envelope with an application portion, a living hinge and an adhesive on the inner periphery of the sleeve. The present invention discloses a simpler construction, without the need for a flexible sleeve or sealing the cover.
Besides providing a barrier to inhibit the transfer of microorganisms, a second feature of the present invention includes a method of dispensing which uses minimal space on the hospital or hotel cleaning carts and at the same time facilitates hygienic delivery for each cover. Because the sanitary covers are dispensed by the housekeeping personnel, having a dispensing system attached to or placed on the cart ensures that each housekeeper will have convenient access to the sanitary covers, without needing to remove a backing or packaging or disposing of additional waste.
There is a need in the art to provide a simple disposable cover which is a secure protective barrier that adequately protects humans against contaminants and at the same time, uses a minimal percentage of synthetic composition in the covering structure. There is also a need for a method of use which utilizes a refillable container with a dispensing apparatus comprised of biodegradable materials, and provides hygienic delivery for each cover in an efficient and cost-effective manner.
The present invention utilizes a simple manufacturing process which joins rectangular top and bottom panels on the outer edges of three sides. As there is no requirement for individual packaging, storing in a reusable container and dispensing from a reusable dispensing apparatus is the preferred method of use. The preferred embodiment for this invention and its dispensing apparatus comprises biodegradable material. With our landfills overflowing with non-degrading materials, another object of the present invention is to provide a flexible, durable and transparent cover manufactured from biodegradable material.
A biodegradable material is one which decomposes in a relatively short time to nontoxic water soluble materials. Light, air, microorganisms and moisture determine the rate of degradation. Using natural raw materials such as starch, cellulose or polylactic acid in the manufacturing of the flexible transparent cover is the preferred embodiment of the present invention, including the dispensing apparatus and container. Although a material containing synthetic polymer is extremely durable, providing durability beyond a single use is not a requirement of the present invention. Therefore, it is desirable and an object of the present invention to incorporate a degradable or compostable material with minimal synthetic component. The biodegradable component may range from 1% to 100% of the whole, with or without the use of additives including, but not limited to mineral fillers, plasticizers, and pigments to improve the thermoplastic properties of the material. Because durability is not the primary attribute of the present invention, the biodegradable component could be increased to maximum limits. Biodegradable compositions such as starch may be modified chemically by the process of cross linking, substitution, or combining with polymers to modify properties of the material. These properties include flexibility, elasticity, durability and moisture-resistance. Other materials, which may be used for the present invention in addition to the preferred embodiment which teaches biodegradable materials, are thermoplastics and paper.
Another object of the present invention is to provide a flexible, durable, moisture-resistant and transparent cover which is housed within a refillable container in which one panel contains a reusable dispensing apparatus, thereby minimizing materials. Although numerous remote control covers have been described in the art, there is a need to provide a cover which may be dispensed hygienically without the need for additional carrier papers and other costly materials. The method described in this innovative art addresses this issue in a way to maximize efficiency, space, and materials while minimizing material waste and the need to dispose of packaging on a daily basis.
Perhaps one of the most important features of the sanitary cover is that it provides users empowerment to avoid potentially contaminating agents. Another object of the present invention is to economically produce a disposable cover used extensively throughout the hotel and hospital supply industry as well as the general population.
It is also the object of this invention to provide a simple sanitary cover which relates in general to the size of the device it is covering. As a result, the variation in sizes of the remote control is accommodated while using fewer basic patterns.
For personal use, the remote control covers may be fastened at one end, and packaged in booklets. Each remote control cover may be removed from the booklet by tearing the perforation. For commercial use, primarily in the hospitality industry and hospitals, single remote control covers manufactured are connected end-to-end in a roll and placed within the dispensing unit. A perforation between single covers enables them to be dispensed one at a time, as they are unrolled and pass through the dispensing apparatus. In an alternative embodiment, covers may be manufactured individually without the need for a perforation.
