Abstract
A protective covering for a hand-held device includes a resilient water-impermeable bag which is of one piece. The bag has a single opening through which the device can be inserted in the bag, and a layer of adhesive runs around the opening on the inside of the bag. The adhesive layer is covered by a nonadhesive strip which can be peeled off to expose the adhesive layer. When the bag is closed following removal of the nonadhesive strip, the adhesive layer forms a water-impermeable seal for the opening of the bag.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to a protective covering for a hand-held device and, in particular, for a communications device.




2. Description of the Prior Art




Portable cell phones, pagers and similar hand-held devices currently enjoy tremendous popularity. These communications devices are carried along virtually everywhere and, as such, are inevitably exposed to the elements and are also liable to be dropped in puddles or snow.




Since water can affect the operation of, and even ruin, a cell phone, pager, or other electronic device, protective coverings have been developed for such communications devices. However, none of these coverings forms an entirely satisfactory barrier to water.




SUMMARY OF THE INVENTION




It is an object of the invention to shield hand-held devices in general, and electronic communications devices in particular, from water more effectively.




The preceding object, as well as others which will become apparent as the description proceeds, are achieved by the invention.




One aspect of the invention resides in a one-shot, i.e., single-use or disposable, protective covering for a hand-held communications device or similar device. The covering comprises a one-piece elastically deformable resilient bag with a single opening. The bag has an undeformed condition and an expanded condition, and the bag is designed to fully enclose the hand-held device when the bag is in the expanded condition. The bag is further designed so that the device is insertable in the bag only upon expansion of the bag from the undeformed condition, and the bag conforms to the shape of the device after its introduction in the bag's expanded condition. The covering additionally comprises a layer of adhesive on the bag arranged to permit substantially complete sealing of the opening in the expanded condition of the bag, and both the adhesive and bag are substantially water-impermeable.




In accordance with the invention, a protective covering for a hand-held device includes a bag for reception of the device. The bag is of one piece and has a single opening which can be substantially completely sealed by an adhesive. The bag, as well as the adhesive for sealing the opening, are substantially water-impermeable. By virtue of these features, the covering enables the hand-held device to be well-protected from water.




Inasmuch as the bag is elastic and designed so that the hand-held device can be inserted therein only when the bag is expanded, the bag can shrink onto the communications device and conform to the contour thereof. This makes it possible for individual elements of the device, e.g., operating keys and the like, to be recognizable from the outside.




Another aspect of the invention resides in a hand-held article, such as a communications article. The article comprises a protective covering free of openings, and the covering includes a water-impermeable elastically deformable bag as well as water-impermeable bonding material sealing the bag against water. The article also comprises a device inside the bag, and the bag elastically grips the device.




An additional aspect of the invention resides in a method of protecting a device. The method comprises the steps of elastically expanding a substantially water-impermeable bag, and inserting the device in the bag while performing the expanding step. The method further comprises the steps of elastically gripping the device with the bag when the device is in the bag, and sealing the bag with substantially water-impermeable bonding material while performing the gripping step.




Other features and advantages of the invention will be forthcoming from the following detailed description of preferred embodiments when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, the numeral


10


identifies a typical communications device. The device


10


is exemplified by a cell phone but could also be a pager or any other device which can receive signals from a remote sender and/or transmit signals to a remote receiver, or an electronic or other device that could similarly be protected from moisture. Such articles could include, without limitation, GPS units, Walkman®-type radios and players, cameras, electronic day-timers, hand-held computers, flash lights, portable televisions, and medicine containers.




The cell phone


10


has an earpiece


12


, a mouthpiece


14


, a display screen


16


, a keypad


18


, an antenna


20


and a jack recess


22


. The cell phone


10


is in the process of being inserted in a protective covering


24


. The covering


24


includes an elastic or resilient bag or pouch


26


which is of one piece. The bag


26


can be elastically expanded or stretched from an undeformed condition, and the bag


26


tends to return to this condition when elastically expanded.




The bag


26


has an opening


28


which serves for insertion of the cell phone


10


in the bag


26


, and the opening


28


constitutes the sole opening of the bag


26


. The opening


28


adjoins a margin


30


of the bag


26


, and the margin


30


extends circumferentially of the bag


26


and circumscribes the opening


28


. Considering

FIG. 2

in conjunction with

FIG. 1

, the inner surface of the margin


30


, that is, the surface of the margin


30


facing the opening


28


, is provided with a layer


32


of adhesive or bonding material. The adhesive layer


32


here runs the length of the margin


30


although this may not be necessary. The main design consideration for the adhesive layer


32


is that the latter be able to completely seal the opening


28


when the bag


26


is closed.




Upon closing the bag


26


, the adhesive layer


32


forms a permanent seal for the opening


28


so that the bag


26


cannot be opened without cutting or otherwise destroying the bag


26


. Accordingly, the protective covering


24


is a one-shot or disposable item, i.e., the protective covering


24


is used once and then discarded.




The bag


26


and the adhesive constituting the layer


32


are water-impermeable. Furthermore, the protective covering


24


is designed to enclose the cell phone


10


entirely when the bag


26


is sealed. Thus, since the bag


26


is a one-piece item and has only the one opening


28


which is completely sealed by the adhesive layer


32


when the bag


26


is closed, the protective covering


24


is capable of effectively shielding the cell phone


10


from water.




The adhesive layer


32


is covered with a nonadhesive strip or layer


34


which prevents the bag


26


from being sealed inadvertently. The strip


34


is provided with a tab


36


which can be grasped to peel the strip


34


from the adhesive layer


32


.




The protective covering


24


is designed so that it is not possible to insert the cell phone


10


therein without expanding the bag


26


from its undeformed condition. This insures that the bag


26


elastically grips the cell phone


10


and conforms to the contour thereof after the cell phone


10


has been placed in the bag


26


.

FIG. 1

shows the bag


26


being held in an expanded condition for insertion of the cell phone


10


in the bag


26


.





FIG. 3

illustrates the protective covering


24


once the cell phone


10


has been placed in the bag


26


and the latter has been sealed by the adhesive layer


32


. The bag


26


has shrunk somewhat from the condition of

FIG. 1

where the bag


26


was being forcefully expanded to a size sufficiently large to insert the cell phone


10


therein. However, the bag


26


is still in an expanded condition in

FIG. 3

since the cell phone


10


is too large to permit the bag


26


to return to its undeformed condition. Since the tendency of the bag


26


is to shrink to the undeformed condition thereof, the bag


26


elastically grips the cell phone


10


and conforms to the contour of the same. Accordingly, the outlines of the earpiece


12


, the mouthpiece


14


, the display screen


16


, the keypad


18


and the antenna


20


of the cell phone


10


are visible in the bag


26


.




To permit identification of the keys of the keypad


18


for dialing purposes, the bag


26


is preferably semitransparent or transparent. Furthermore, the bag


26


should be capable of transmitting the sounds coming from the earpiece


12


as well as the sounds spoken into the mouthpiece


14


. The bag


26


is advantageously designed to transmit sound with little or no distortion or attenuation. The bag


26


should also be capable of transmitting the electrical signals necessary for the operation of the cell phone


10


.




By way of example, the bag


26


can be made of latex. Latex is resilient, capable of transmitting sound and electrical signals, and at least semitransparent in the form of thin sheets,




Assuming that the bag


26


is in its undeformed condition, a method of protecting the cell phone


10


from water is as follows. The bag


26


is elastically expanded at least in the area of the opening


28


. While the bag


26


is elastically expanded, the cell phone


10


is inserted in the bag


26


via the opening


28


. It was previously mentioned that the bag


26


can accommodate the entire cell phone


10


. In fact, the cell phone


10


can fit inside the bag


26


without obstructing the rim


30


, and the cell phone


10


is positioned in the bag


26


in this manner. Since, as indicated earlier, the cell phone


10


is too large for the bag


26


when the latter is in its undeformed condition, the bag


26


elastically grips the cell phone


10


and conforms to the contour thereof.




Once the cell phone


10


has been placed in the bag


26


, the tab


36


of the nonadhesive strip


34


is grasped to peel the strip


34


from the adhesive layer


32


. The opening


28


of the bag


26


is then completely sealed by the adhesive layer


32


.




The protective covering


24


effectively shields the cell phone


10


from water. This is so because the bag


26


is of one piece, is water-impermeable and has only one opening


28


which is completely sealed by the water-impermeable adhesive layer


32


. Furthermore, since the bag


26


is resilient and must be elastically expanded to accommodate the cell phone


10


, the protective covering


24


conforms to the contour of the cell phone


10


. This allows individual elements of the cell phone


10


to be recognizable from the outside of the protective covering


24


.




While the invention has been described in terms of a protective bag for a cell phone, it is clear that it can be applied in equivalent fashion to any other hand-held article in need of protection, as listed above by way of examples. For instance,

FIGS. 4 and 5

illustrate the protective bag


26


of the invention stretched and sealed over a portable radio


40


and an electronic day-timer


50


.




Various modifications are possible within the meaning and range of equivalence of the appended claims. For instance, the seal formed by the adhesive layer


32


can be replaced by a heat seal, a Zip-Lock® closure, or any other equivalent sealing means capable of guaranteeing waterproof closure.
