Selected and edited published applications from recent editions of the patents
journal. This month is Category B: ‘performing operations; transporting’
special inks or processes. In so doing,
the resolution of patterns changes or
the colours thereof change, or patterns
develop or a pattern shift occurs. In
addition, the present invention relates to a
method of recognising authenticity of the
manufactured anti-counterfeiting sheet with
a smartphone.
In order to achieve this goal, the anticounterfeiting
sheet includes a transparent
substrate having a rst pattern formed on
one surface and a second pattern formed
on the other surface. The rst pattern is
con gured to include a plurality of rst
elements and rst blanks, and the second
pattern is con gured to include a plurality
of second elements and second blanks;
and all or a part of the rst element is
hidden by the second element when the
second element is viewed directly from
above, and the rst pattern is visually
recognised at a predetermined viewing
angle through the second’s blanks.
The anti-counterfeiting sheet may
further include a third pattern formed on
the other surface opposite to the one
surface on which the rst pattern of the
rst substrate is formed, wherein the third
pattern is con gured to include a plurality
of third elements and third blanks, and
the rst pattern is visually recognised at a
predetermined viewing angle through the
third blanks.
To recognise the authenticity of the
anti -counterfeiting sheet involves a user
terminal having an App and a camera,
in which the rst pattern is designed to
include an identi cation pattern. Having
received an image of the anti-counterfeiting
sheet through the camera, the App,
which has pre-loaded information about
the identi cation pattern, determines its
authenticity by detecting the identi cation
pattern from the received image.
Anti-vacuum bin liner
GB2574053A
Karl William McAllister
A bin liner of plastic material used in
conjunction with a waste bin (receptacle)
for the collection of waste is stored
usually in the kitchen in the home. The
liner is inserted into the receptacle, then
opened with the top edges of the liner
wrapped over the edges of the receptacle
and held in place by the top of the bin lid
overlapping the main body’s edge, trapping
the liner in the process.
Once the liner is full, the waste
collected becomes compacted against
the walls of the body of the receptacle,
creating a vacuum between the liner and
receptacle wall. As the liner is pulled
upward, vacuum pulls the liner back,
making it harder to remove.
Bin liners with a drawstring built into
the hem of the opening to assist in closing
and securing the contents are liable to tear
when being lifted out of the receptacle by
the drawstring, because the pressure of
the vacuum holds the liner rmly, resulting
in the stretching and thinning of the
material and liable to tearing.
The invention concentrates on breaking
the vacuum between the liner and wall
of the receptacle by attaching a band/
drawstring to the bottom of the liner along
the outer side wall to the top opening, via
a hem along the side, or loose against the
outer wall of the liner.
When the band is pulled upwards,
the contents of the liner are compacted
slightly, pulling the side of the liner
away from the wall of the receptacle and
breaking the vacuum. That makes the liner
easier to remove.
When tied together at the top, the
drawstring/s or band/s will also help
Anti-counterfeiting sheet using

Anti-counterfeiting effects have a problem
in that the material cost is high or the
manufacturing process – such as using
expensive special inks of thermochromic,
photochromic, or time-varying inks, using
intricate processes such as intaglio
printing, using a special bre material,
or injecting a special effect in the sheet
manufacturing stage – is complicated.
The invention relates to an anticounterfeiting
sheet and a manufacturing
method for that, in which a colour shift,
a latent image, and a security window
can be implemented at low cost using
ordinary inks and printing rather than
