THE CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS:

1. A tea bag and cover, the cover comprising two leaves
joined together about a fold line, said tea bag being
attached by attachment means to one leaf adjacent said
fold line whereby said fold line is above said attachment

5. means to enable the leaves to fold to one side of the
bag with no part of either leaf being on the cup side
of the bag when suspended in a cup by inserting the bag
inside the cup with one leaf passing down the outside
of the cup.

2. A tea bag and cover as defined in claim 1, characterized in that the attachment means is a staple, the rim of
the cup resting on the area of the bag and respectively
adjacent the staple so that the bag generally conforms
5. to the shape of the cup.

3. A tea bag and cover as defined in claim 2, characterized in that the cover is a single sheet, a fold line being
provided across the centre of the sheet, the staple being
applied just below the fold line through one leaf only
5. of the sheet.

4. A tea bag and cover as defined in claim 1, wherein
the cover is formed from a sheet of paper.

5. A method of manufacturing a tea bag and cover, the tea
bag having a crimped peripheral flange, the method comprising the steps of providing a sheet of paper to form the cover,
stapling the tea bag to the sheet of paper at a position

5. below the transverse centre line of the sheet and forming a
fold line on the transverse centre line of the sheet to form two leaves to overlie the tea bag.

6. An infusion package comprising a porous bag for
an infusible substance and a relatively stiff sheet secured, at a securement region, to only one side of the intended
top edge of the bag, thereby to enable the bag to be
5. suspended on a container edge with the sheet then being
located entirely outboard of the securement region in a
cantilever manner to balance the bag on the rim of the
container.

7. An infusion package comprising a porous bag for
an infusible substance and a relatively stiff sheet secured at a securement region to only one side of, and at only
a central region along the length of, the intended top
5. edge of the bag when suspended in a cup, thereby enabling
end regions of the top edge of the bag to move away from
the sheet and generally to conform to the curvature of
the cup .

8. An infusion package comprising a porous bag for
an infusible substance and a relatively stiff sheet of
material secured at a securement region to only one side,
and only at a central region along the length of, the
5. intended top edge of the bag when suspended in a cup,
thereby to enable the ends of the top edge to separate
from the top edge of the sheet and for the cup to support
the package by being wedged, on the one hand by a portion
of the sheet on the outside of the cup and below the
10. securement region, and, on the other hand, a portion
of the bag below the upper edge thereof which can curve
to conform to and rest against the inside of the cup
below its rim.

9. A method of infusing a substance into a liquid,
in which the substance is contained in a porous bag,
the bag being attached at its upper edge to a sheet of material just below a centre horizontal fold line across 5. the sheet of material to form two leaves extending down
one on each side of the bag, the method comprising the
steps of folding the unattached leaf back fully, placing
the bag over the rim of the cup with the attached leaf
extending down the outside of the cup, so that the edge

10. of the cup is wedged between the bag and the attached
leaf thus exposing the open area of the cup, adding water to the cup to cover the bag, to infuse the substance
into the water, and after infusion folding the unattached leaf down as the bag is removed, the bag being held above

15. the cup to squeeze the bag to remove excess infused liquid and disposing of the bag.

10. A tea bag and cover substantially as hereinbefore
described with reference to and as illustrated in the
accompanying drawings.
