Description
BACKGROUND OF THE INVENTION
This invention relates to a labelling system, particularly, but not limited to, labels for information bearing media and also an applicator for applying labels to information bearing media.
An existing method for applying a label to a CD (which may be a music CD, a CD ROM or a re-writable CD) or a DVD or the like comprises removing an adhesive label which is die cut from a larger sheet secured to a backing sheet, and placing the label in position on the CD.
Disadvantages arise with this method because a user has difficulty in correctly locating the label relative to the CD. It is very difficult to place the label centrally on the CD by eye. Disadvantages arise because the appearance is incorrect. Also, if the label protruded over the edge of the CD, then the machine reading the CD may malfunction.
An attempt to overcome the above mentioned problem has made use of an applicator to apply a label to a CD or the like. The applicator is used by taking a label from its backing sheet as described above, placing the label in the applicator, then placing the CD in the applicator. The applicator is then activated to press the label onto the CD.
Disadvantages arise with the applicator described because it is very cumbersome and expensive.

DETAILED DESCRIPTION OF THE INVENTION
A label
10
for a shaped CD ROM (not shown) is located on a backing sheet
12
. The label
10
has a central opening
14
which is larger than the central opening in the shaped CD ROM with which the label is to be used.
FIG. 4
shows an applicator
16
which is used to apply the label
10
to the shaped CD ROM. The applicator
16
comprises a central projection
18
and peripheral locator pins
20
a
and
20
b
. The applicator also comprises a well
22
in which to receive the shaped CD ROM.
In more detail, the label
10
is held on a sheet
24
comprising a plurality of labels
10
. The central opening
14
has a diameter of 15.2 mm formed by removal of a die cut disc portion
15
. The label
10
is shaped to be slightly smaller than the shaped CD ROM. The shape is that of a disk with two sections removed from opposite edges. The curved edges of the label have a radius of 39.5 mm. The width of the label between the flat edges is 60 mm.
Each sheet
24
comprises a layer of adhesive backed paper with a backing sheet
12
. The labels
10
are die cut on the sheet
24
so that some of the material of the adhesive backed sheet remains after the labels
10
have been die cut and subsequently removed.
The adhesive backed sheet
24
is also die cut to form disc portions
26
a
and
26
b
at opposite sides of the central opening
14
. The position of the disc portions
26
is chosen to correspond to the position of the peripheral locator pins
20
a/b
when the label is located in the well
22
of the applicator
16
. The disc portions can be removed by pressing them out of the remaining material.
The feature of the backing sheet
12
being die cut is in contrast to existing methods of applying labels to data storage media in which only the label is die cut.
FIG. 2
shows the backing sheet
12
.
The backing sheet
12
is die cut to be 1.5 mm larger than the majority of the periphery of the labels
10
. The radius of the curved part of the backing sheet
12
or a particular label
10
is 41 mm. The width between the cutaway sections of the backing
12
for a particular label
10
is 63 mm.
The section of die cutting on the back sheet
12
for a particular label
10
also comprises tab portions
28
a
and
28
b
. The location of the tab portions
28
a/b
are chosen to extend over the peripheral locator pins
20
a/b
when the section of backing sheet
12
corresponding to a particular label
10
is placed in the applicator
16
. Each tab portion
28
a/b
has a disc shape
30
a/b
removed therefrom in a location corresponding to that of the disc portions
26
a
and
26
b
and the adhesive backed sheet
24
. The removal of the disc portions
30
a/b
creates openings which can be placed over the peripheral locator pins
20
a
/
20
b
to locate the label
10
.
The backing sheet
12
is also die cut to allow for removal of a disc
32
of the backing sheet
12
which corresponds in size and location to the central opening
14
in the label
10
.
In use, a section of the sheet
24
bearing a label
10
and its piece of backing sheet
12
is removed from the sheet
24
by pushing the section of backing sheet
12
to disengage that piece from the remainder of the sheet
24
. The section of backing sheet
12
bearing the label
10
is larger than the label
10
. The discs
26
a/b
and
30
a/b
are then pushed through to leave openings in the tab portions
28
a/b
. The disc
32
is also removed to form the central opening
14
.
The backing sheet
12
and label
10
combination is then placed over the applicator
16
so that the openings in the tab portions
28
a/b
are received on the peripheral locator pins
28
a/b
and so that the central opening
14
and the label
10
is received on the central projection
18
. The location of the tab portions allows for the label
10
to be orientated correctly, so that any matter printed on to the label
10
is correctly orientated with respect to the shaped CD ROM. When the backing sheet
12
and label
10
have been located correctly in the applicator
16
, the section of backing sheet
12
is removed to leave the label
10
located in the well
22
of the applicator
16
, with the adhesive face of the label
10
facing upwards. The CD ROM is then placed onto the label
10
and pushed down into the well
22
of the applicator
16
. The pressure on the CD ROM causes the label
10
to adhere to the CD ROM, which can then be removed from the applicator.
In the manner described above, the label
10
is correctly orientated on the CD. Also, it is not necessary for a user to touch the adhesive side of the label
10
, because the section of backing sheet
12
can simply be peeled from the label
10
whilst the label is held in the well
22
of the applicator
16
. Thus, the disadvantage with prior art methods of having to remove the label by hand from its backing sheet and placing that label in an applicator by hand is avoided. The primary reason for this benefit is the fact that the backing sheet
12
is also die cut, as well as the label
10
.
FIGS. 3 and 4
show an alternative embodiment of label
40
held on a backing sheet
42
(see
FIG. 4
) each label
40
has a central disc section
44
die cut therefrom, which disc section
44
can be removed to reveal a central opening in the label
40
. The label is circular having a diameter of 117.5 mm. The disc
44
has a diameter of 41.3 mm.
A section
46
of the backing sheet
42
is also die cut. The sections
46
a
is slightly larger than the label
40
and has a diameter of 120.5 mm. The section
46
of the backing sheet
42
may also have a central disc die cut, which disc has a diameter of 41.3 mm and corresponds to the location of the disc
44
die cut from the label
40
.
The section
46
of the backing sheet
42
also has tab sections
48
a/b
on the periphery thereof. The tab sections have a width of 15 mm and a generally curved outer shape. The tab sections
48
a/b
are provided to allow location of the label
40
and its section
46
of backing sheet
42
in an applicator
50
(see FIG.
7
).
The applicator comprises a well
52
which has the same size and shape as the section
46
of the backing sheet
42
mentioned above. The well has a central projection
54
which corresponds in size and shape to the disc
44
which is die cut from the label
40
. The well
52
also includes tab receiving sections
56
a/b
in which the tab sections
48
a/b
of the section
46
of the backing sheet
42
are arranged to be received. The provision of the tab sections
48
a/b
and the tab receiving sections
56
a/b
and the applicator
50
allows for the location of the label in the applicator in a unique position. The unique position is necessary so that label
40
can be correctly orientated when it has been printed in a previous operation. Rotation of the label is deterred by the tab portion.
As with the first embodiment described in relation to
FIGS. 1
,
2
,
5
and
6
the section
46
of the backing sheet
42
with the label
40
thereon is removed from the remainder of the backing sheet
42
. The section
46
is then placed in the well
52
of the applicator
50
, the section
46
of backing sheet
42
is then removed leaving the label
40
with its adhesive side up in the well
52
. A CD or the like can then be placed and pushed down on the label
40
so that the two are stuck together.
As before, the method and apparatus as described above makes good use of the advantageous die cutting of both the label
40
and the backing sheet
42
.
