Detailed Description

[0029] Generally, disclosed herein are various embodiments of a metal purse, which may be in the form of a clutch. For simplicity, we will refer to such a purse or clutch generically as a purse. As is common in the industry, the purse is made up of an outer portion and an inner lining. In this case, the outer portion is, in fact, a metal shell. The metal shell is generally in a bivalve construction, having a hinge connecting two halves which rotate about the hinge to expose the interior of the purse. In some embodiments, the exterior surface of the metal shell may be painted or otherwise coated for decorative and/or protective purposes. In some embodiments, at least one half of the bivalve, and in most instance both halves, are provided with an outer shell, which may be decorated. The outer shell may be of any suitable material, with plastics and polycarbonate being particularly well suited to the task.

[0030] The metal shell can take any shape or geometry and any type of construction. Particularly, a bivalve construction having two halves affixed to each other via one or more hinges provides a good balance of aesthetics and functionality. The metal shell may be made of any suitable metal or metal alloy. Without limitation, the metal shell may be made of steel, stainless steel, aluminum, copper, bronze, precious metals such as gold and silver, or combinations thereof. Each metal shell is substantially solid, although some embodiments may be provided with perforations and or one or more slot as described further below.

[0031] The lining may be any appropriate material, and is usually cloth or leather. A lining is not necessary to proper operation of the purse, and therefore may be omitted in some embodiments. The lining, when present, has aesthetic value and function in that it cushions items contained in the purse, may provide pockets or other details, and reduces the sound of items moving within the purse.

[0032] The purse may also be configured with a stop to prevent over rotation of the hinge, or to limit its travel to a predetermined angle, for example 90 degrees or 110 degrees. In some instances this is desirable to prevent the purse from inadvertently opening fully and releasing it contents.

[0033] The purse may further be provided with a latch to keep the purse closed when desired. Alternatively, the purse may contain spring-loaded hinged or similar mechanism to bias the purse into a closed position to secure its contents. As will be appreciated by those of skill in the art, the purse may also be adapted to hold open again via spring-loaded hinges or with support arms and the like. In some embodiments, a decorative latch may be used in conjunction with these other methods.

[0034] FIGs. 1-5 show a purse in accordance with some embodiments. FIG. 1 depicts a purse 100, having a metal shell 10A, 10B in a bivalve construction. A decorative latch 500 is also shown in FIG. 1. As shown, the purse is generally rounded and oblong in shape. The purse may be any desired shape and size. As depicted, the metal shell is smooth and rounded. Other shapes such as square, rectangular or other shapes may be employed without straying from the scope and spirit of this disclosure.

[0035] FIG. 6 shows a perspective view of the purse in an open position. This position reveals the interior of the purse, defined by the metal shell, and the hinge connecting the two halves of the bivalve metal shell. The hinge can be any conventional hinge used to connect two bodies for rotation with respect to one another, such as a piano hinge or the like.

Depending on the size and configuration, a single hinge or multiple hinges may be used. In some embodiments, the metal shell is provided with a recess to accommodate the hinges. Although the figures and this description focus on a bivalve construction, other constructions are possible.

[0036] In some embodiments, the outer surface of the metal shell can be covered with paint, powder coating, or other surface treatment. In some embodiments, the metal shell may be covered with an outer decorative shell. The outer shell can be of any suitable material, but is generally plastic or polycarbonate. In some embodiments, the outer shell is hard plastic or polycarbonate affixed to the outer surface of the metal shell. The outer shell may be affixed to the metal shell by friction, adhesive, or other suitable means. In some embodiments, the outer shell is permanently affixed to the metal shell, that is, it is not intended to be removed by the end user. In other embodiments, the outer shell may be designed to be removable, either to interchange one or more outer shell designs, or to allow the user to expose the underlying outer surface of the metal shell (finished or unfinished). Each outer shell may be adorned with a desired design element or color. The outer shell may be of any shape, but typically will take a complementary shape to the underlying metal shell, essentially providing a decorative skin to the metal shell. In some embodiments, the outer shell can be textured to provide another design element.

[0037] In modem society, you would be hard pressed to find a purse that did not contain a wireless device such as a cellular phone or a tablet. A fully closed metal purse effectively prevents wireless signals from entering or leaving the purse. Thus, a fully closed metal purse could be an effective solution if one desired to stop wireless communication, say in a theatre or at dinner. However, most people today are reluctant to be cut off from their wireless communications. Accordingly, a modem metal purse should account for this and allow for the passage of wireless signals into and out of the purse such that no loss of wireless communication occurs. Fashion, however, demands that this be accomplished in the most minimally invasive way possible. [0038] Accordingly, some embodiments are provided with an opening to allow for better signal strength within the purse. The opening can be provided in any number of ways, including providing a plurality of perforations in the metal shell, providing one or more slots in the metal shell, or providing a gap between the two metal shells, or a combination of these. The type of metal used also impacts the signal strength, but can be overcome by providing the right opening.

[0039] Stainless steel and aluminum purses were prepared with a plurality of

perforations, a slot, and a gap, respectively. Although signal strength improved with all three methodologies, the best improvement was found with a gap between the metal shell halves. The tables below illustrate some examples. Keeping in mind that signal strength closer to zero indicates a stronger signal. It can be seen that in steel and aluminum, purses with no gap have a weak signal strength of about -130dBM compared to -82 and -86 when the phone is sitting in an open half shell. As shown below, just a 0.027 inch gap in the steel purse improves signal strength considerable. The tables also show similar improvements with slots or perforations and a gap. It should be noted that in these tests, an iPhone 4 did not ring below about -1 lOdBM. Thus, in the closed purse at -130dBM, the phone signal strength was insufficient for reception, while with the gap achieving -102 or -lOldBm the signal strength was sufficient to receive a call.

Signal Strength dBm

Phone on table -71

Phone in steel shell half -82

Steel, no gap -130

Steel with 0.013" gap -102

Steel with 0.027" gap -101

Phone in Aluminum shell half -86

Aluminum, no gap -130

Aluminum, Perforated (7 x 0.125" diameter) -114

Aluminum, Slot with no gap (0.125 X 2.125") -112

Aluminum, Slot with 0.013" gap -103

Aluminum, Slot with 0.027" gap -106

Aluminum, Slot with 0.041 " gap -101

Aluminum, Slot with 0.055" gap -97

[0040] Accordingly, in some embodiments, a gap is provided sufficient to yield a signal strength of at least -1 lOdBm in the purse, when closed. In some embodiments, the gap is sufficient to provide a signal strength of at least -106dBm, at least -105 dBm, at least - 103dBm, at least -102dBm, at least -lOldBm, at least -lOOdBM, at least -97dBm, at least - 95dBm, at least -93dBm, at least -90dBM or any value or range of values therebetween, including endpoints.

[0041] In some embodiments, a gap distance of about 0.010 inch to about 0.010" is provided substantially around a peripheral edge. In most instances this will be at the location where the portions of the metal shell meet each other in a closed position. Rather than being completely closed, a gap of the desired distance is provided and maintained when the purse is closed. The gap may be about 0.010 inch, about 0.015 inch, about 0.020 inch, about 0.025 inch, about 0.027 inch, about 0.030 inch, about 0.035 inch, about 0.040 inch, about 0.041 inch, about 0.045 inch, about 0.050 inch, about 0.055 inch, about 0.060 inch, about 0.070 inch, about 0.080 inch, about 0.090 inch, about 0.010 inch or any value or range of values between any of these values, including endpoints. The desired gap may be made and maintained by any suitable means. In particular, one or more spacers can be employed along one or both edges of the metal shells, to maintain the desired gap distance. The spacers may be integrally formed with the metal shell, or may be provided separately by affixing metal, plastic, cloth, rubber, or other material to one or both edges of the metal shells. Alternatively or additionally, a latch mechanism may be employed that locks the metal shells when closed while maintaining the desired gap distance. Fig. 7C shows a spacer used for experimental purposes, it should be clear to those of skill in the art that the spacers employed in the purse will be relatively discrete and be limited in size based on the thickness of the metal shell so as to be as unobtrusive as possible. It is contemplated that, although the gap is relatively small and nearly imperceptible, one might want to completely close the purse to purposefully block reception. Thus, in some embodiments, the spacers may be removable or displaceable to a position where they do no create or maintain a gap. The effect can be enhanced through the use of a floating hinge, so that when spacers are present, the hinge floats or expands to accommodate an even gap around the substantially the entire periphery. When the spacers are removed or retracted, the hinge retracts, forming a completely closed seal.

[0042] Figs. 1 1 and 12 depict a purse according to one embodiment, and clearly show the gap between the two halves. In this embodiment, the gap is substantially uniform around substantially the entire perimeter. It should be noted, that certain structural elements, such as hinges, strap connectors, and other elements may occupy a portion of the gap without affecting its function in an appreciable way.
