exothermic composition capable of generating heat in the
presence of air wherein the air-permeable bag is formed with a
non-slip layer in at least a portion thereof, the non-slip
layer being an outermost layer of the air-permeable bag; and
an airtight bag sealingly enveloping the air-permeable bag.
Kiyohara discloses a disposable foot warmer. As shown in
Figures 1-2, the foot warmer includes an air-permeable bag 10
accommodating an exothermic composition 16 capable of
generating heat in the presence of air and an airtight bag 20
sealingly enveloping the air-permeable bag. The air-permeable
bag 10 is coated with an acrylic resin tackifier in at least a
portion thereof for securing the air-permeable bag 10 in place
during use after the air-permeable bag 10 has been removed
from the airtight bag 20. The tackifier coating layer 14 is
covered with a piece of peelable paper 15 which is removed to
expose the tackifier coating layer 14 after the air-permeable
bag 10 has been removed from the airtight bag 20.
The appellant argues (brief, pp. 3-4; reply brief, p. 1)
that claims 10 to 16 are not anticipated by Kiyohara.
