BACKGROUND
[00021 This disclosure relates to shieldable containment devices and systems,
and more particularly to reusable shieldable bags for containing items that
may be
carried by an individual, including a system and devices capable of blocking
RF,
infrared and scan technology.
000031 There are more frequent uses of embedded storage media, such as chips,
magnetic and other memory storing media in use today. For example, credit and
debit cards, as well as identification cards for healthcare and insurance
memberships, commonly utilize a magnetic strip that may be encoded with
information. The coded stored information may be read when passed through a
,
scanner so that a merchant or other service provider may read the information
and/or import the information into a computer, such as a database or billing
system.
Other items, such as passports, used to identify individuals, contain
digitally stored
1

CA 02787634 2012-08-22
information which may read by placing the passport in the vicinity of a
scanner.
Also, the same scanning technology may be used to track a cell phone.
[0004] However, not only may intended decoders and readers, such as card
scanners, or passport scanners read the information, but also scans may be
carried
out even without the individual intending or knowing that scanning is
occurring.
There is a great risk that information may be retrieved without authorization
from a
stored source, such as the aforementioned types or others, and used for
unethical
or unlawful purposes. in the era of increased security concerns, it is
important to
protect against identity thefts and espionage activities.
[0005] A need exists to avoid such scanning and tracking via an easy and
economical device or system that may be used to store items which a person may
generally carry on them, such as cell phones, credit and identification cards,
and
passports, and shield the stored contents from electromagnetic interference,
such
as, for example, electromagnetic radiation, including, for example, infrared,
radio
frequency and magnetic card decoders.
SUMMARY
[0006] One embodiment of the present disclosure provides a shielding apparatus
including a double-lined container having an outer pocket and an inner pocket
mounted within the outer pocket The inner and outer pockets each form an
enclosure having a continuous dosed edge interrupted by an opening. The
continuous closed edge of the outer pocket is adjacent the continuous closed
edge =
of the inner pocket, and the opening of the outer pocket is adjacent the
opening of
the inner pocket The adjacent openings are interconnected and include a device
for

plurality of stitches and folds are included in the continuous and dosed edge
of the
inner pocket and a second plurality of stitches and folds are included in the
continuous closed edge of the outer pocket. The first plurality of stitches
and folds
are positioned on the inner pocket so as to avoid both alignment and overlap
with
the second plurality of stitches and folds on the outer pocket

DETAILED DESCRIPTION
[0017] A shieldable containment device is formed of a fabric which comprises a
fabric Faraday cage. Because stitching is preferably used to assemble the
fabric to
a desired configuration, and because the stitching penetrates and compromises
the
shielding capabilities of such a fabric, a novel sack configuration is
required.
[0018] In Fig. 1 and Fig. 2 an embodiment of a shielding device includes an
outer
pocket 10 formed of a suitable material 12. Pocket 10 includes a fold line 14.
Outer
pocket 10 includes, as viewed in Fig. 1 and Fig. 2, a top edge 16, an opposite
bottom edge 18, a first side edge 20 and an opposite side edge 22. Folding the
material 12 at fold line 14, in the direction indicated by an arrow designated
Fl,
forms a first panel 12a and a second panel 12b of material 12, and aligns top
edge
16, adjacent bottom edge 18. Also, portions 20a and 20b of side edge 20 are
adjacently aligned as are portions 22a and 22b of side edge 22. The side
portions =
20a and 20b are stitched together by stitches 24 and the side portions 22a and
22b
are stitched together by stitches 26, Fig. 2. The resultant outer pocket 10
thus
includes a continuous closed edge comprising in sequence, a stitched edge 20a,
4

CA 02787634 2012-08-22
,
20b, a folded edge along fold line 14, and a stitched edge 22a, 22b. Top edge
16 is
adjacent bottom edge 18 forming an open end 28.
100193 In Fig. 3 and Fig. 4, another portion of the shielding device comprises
an
inner pocket 30,,also formed of the material 12. Pocket 30 includes two fold
lines 32
and 34. Inner pocket 30 includes, as viewed in Fig. 3, a top edge 36, an
opposite
bottom edge 38, a first side edge 40 and an opposite side edge 42. Folding the
material 12 at fold fines 32 and 34, Fig. 4, in the direction indicated by a
pair of
respective arrows designated F2 and F3 forms a first panel 12c and a second
panel
12d of material 12, aligns side edges 40,42. aligns portions 36a, 36b of top
edge 36
adjacent a portion 36c of top edge 36, and aligns portions 38a, 38b of bottom
edge
38 adjacent a portion 38c of bottom edge 38. The adjacent edges 40,42 are
stitched together by stitches 44 and portions 38a, 38b are stitched to portion
38c by
stitches 46. The resultant inner pocket 30 thus includes a continuous closed
edge
comprising in sequence, a folded edge along fold line 32, a stitched edge 38
formed ,
by portions 38a, 38b, 38c, and another folded edge along fold line 34. Top
edge
portion 36c is adjacent top edge portions 36a, 36b forming an open end 48.
100293 The outer pocket 10 and the similar sized inner pocket 30 being
constructed as described above, may be joined to form an effective shielding
device. The inner pocket 30 may be mounted within the outer pocket 10 by
inserting
the inner pocket 30 in the outer pocket 10 in the manner described below.
[00211 As mentioned above, stitching of the fabric compromises the shielding
capabilities of the fabric. This stitching used in the inner and outer pockets
may
permit leakage of signals into or out of the shielding device when stitches
used in :
the outer pocket 10 are aligned with or immediately adjacent to stitches used
in the
inner pocket 30. However, as will be seen, the stitches used in the inner
pocket 30

CA 02787634 2012-08-22
are neither aligned with nor immediately adjacent the stitches used in the
outer
pocket 10.
[0022] More specifically, Figs. 5,6 and 7, inner pocket 30 including a
continuous
dosed edge of a first sequence comprising a folded edge along fold line 32, a
stitched edge 38 including portions 38a, 38b and 38c, (see also Fig. 3) and
another
folded edge along fold line 34, may be inserted in outer pocket 10 and
oriented so
that the outer pocket folded and stitched edges are of a second sequence,
different
from the -first sequence. That is, the continuous closed edge of the outer
pocket 10,
having a stitched edge 20 including portions 20a, 20b, (see also Fig. 1) a
folded
edge along fold line 14 and a stitched edge 22 including portions 22a, 22b,
(also in
Fig. 1) is in the second sequence, such that the folded edge along fold line
32 of
inner pocket 30 is immediately adjacent the stitched edge 20 of the outer
pocket 10,
the stitched edge 38 of inner pocket 30 is immediately adjacent the folded
edge
along fold line 14 of outer pocket 10, and the folded edge along fold line 34
of inner
pocket 30 is immediately adjacent the stitched edge 22 of outer pocket 10.
[0023] It should. also be Mentioned that edges 40,42, stitched together by
stitches 44 are not a part of the continuous dosed edge of inner pocket 30 and
thus,
stitches 44 are positioned adjacent panel 12a of outer pocket 10, and are not
adjacent any of the stitched edges of outer pocket 10. Furthermore, as can be
seen, when inner pocket 30 is fully inserted into outer pocket 10, in the
direction of
an arrow designated I, Figs. 5,6 and 7, the respective edges 16 and 18 of
outer
pocket 10 and inner edge 36 of pocket 30, are immediately adjacent one another
as
are their respective openings 28 and 48.
[0024] The adjacent open edges 16, 18 and 36, Fig. 8, are stitched together at
50, forming a double lined containment device 52 having a single opening 54.
Means 56a and 56b are provided for simultaneously opening and closing the now
6

CA 02787634 2012-08-22
single opening 54. Again, in Fig. 8, the means 56 for opening and closing may
comprise a commercially available Velcro brand hook 56a and loop 56b
fastening device suitably secured around the inner periphery of the single
opening
54.
[0025] Because stitching 50 of the fabric 12, described above, at the single
opening 54 may compromise the shielding capabilities of fabric 12, what is
required
is an appropriate closure of containment device 52 in addition to the hook 56a
and
loop 56b fastening means.
[0026] To accomplish this closure, a double fold system is provided so that
the
closure of containment device 52 may further seal against penetrating and/or
leaking signals. In Fig. 9, opening 54 is closed. Additional closure means may
include an additional hook member 58a and loop member 58h. For example, hook
fastener member 58a may be provided on a first side 52a of a containment
device
52 positioned below a fold line 60, see Fig. 9 and Fig. 10. Loop fastener
member
58b may be provided on a second side 52b, opposite side 52a adjacent another
fold
line 62.
[0027] The double fold system may be accomplished by folding a top end 52c of
containment device 52 at fold line 62 1800 toward a bottom end 52d in a first
rotating
motion as indicated by the arrow designated Rl_ The rotating motion positions
loop
member 58b adjacent first side 52a of containment device 52 and immediately
adjacent hook member 58a, see Fig. 10. Next, Fig. 11, the top end is folded
again
at fold line 60 another 1800 toward the bottom and 52d in a second rotating
motion
as indicated by the arrow designated R2. The second rotating motion engages
loop '
fastener member 58b with hook fastener member 58a in a superimposed manner
and hidden by the last mentioned fold.

CA 02787634 2012-08-22
[0028] According to the above, a personal device 100, Fig. 11, contained in
the
containment bag 52, is shielded by the fabric faraday cage described above so
that
all signals are blocked from entering or leaking from the bag 52. The multiple
thickness fabric bag 52 is usable with mobile devices including, but not
limited to
Smartphones, tablets and I Pads. When such a device is placed in the bag 52,
and
the bag is folded closed, the-device and its file contents become invisible.
Phones
will not ring. Items with ID chips cannot be scanned. Vital information is
secure and
tracking is impossible. This is important because the I Phone has a tracking
device
that cannot currently be turned off. Once placed inside the bag 52, personal
information is guarded and personal identity is protected from being read,
scanned,
or intercepted by skimming devices. A preferred material which may be used to
make the bag 52 is the product Silver Plated Nylon Rip Stop Fabric?' supplied
by the
Carolina Silver Co. of Maiden, N.C. The material used for stitching may be any
suitable thread which is commercially available.
, [0029] Although illustrative embodiments have been shown and described, a
wide
range of modification, change and substitution is contemplated in the
foregoing
disclosure and in some instances, some features of the embodiments may be
employed without a corresponding use of other features. Accordingly, it is
appropriate that the appended claims be construed broadly and in a manner
consistent with the scope of the embodiments disclosed herein.
