Abstract

The disclosure relates to a disposable strainer for infusion of a beverage such as tea in a drinking vessel, the strainer being formed to seat in the vessel and having a closed lower end and an openable top to receive a particulate material and a liquid for infusion with the particulate material. The strainer is formed from a porous flexible sheet material (10) having lifting handles (16) at its upper end on either side of the strainer to enable the strainer to be removed with the residue particulate material after the infusion process leaving the infused liquid in the vessel for consumption.

Description

IMPROVEMENTS IN OR RELATING TO STRAINERS FOR INFUSION OF
BEVERAGES IN A DRINKING VESSEL
This invention relates to strainers for infusion of a beverage in a drinking vessel and is particularly although not exclusively applicable to the infusion of tea or similar herbal drinks.
Conventionally tea is either prepared in a teapot with either a supply of loose tea or a supply of teabags for infusion with boiling water in the pot. Where loose tea is provided, a strainer is normally used to remove the resulting tea leaves which pour with the tea from the pot to prevent the leaves reaching the teacup. The strainer is not required for teabags where the tea leaves are retained in the porous bags. On the other hand the tea normally used in teabags may not be of the same quality as loose tea and resulting in a less satisfactory drink.
A teapot is normally used for infusion of tea when several drinks are required to be provided. Where a single drink only is required, it is common to infuse a teabag with boiling water in a cup. However, as indicated above, the tea formed from teabags is generally of poorer quality as a result of the quality of the tea often used in teabags.
There is a need therefore for providing an arrangement which can be used for making one off high quality cups of tea without the need to use a teapot and loose leaf tea.
This invention provides a strainer for infusion of a beverage in a drinking vessel, the strainer being formed to seat in the vessel and having a closed lower end and an openable top to receive and a particulate material and/or liquid for infusion with the particulate material, the strainer being formed from a porous flexible sheet material having lifting handles at its upper end on either side of the strainer to enable the strainer to be removed with the residue of particulate material after the infusion process leaving the infused liquid in the vessel for consumption.
Preferably the upper end of the strainer has a pair of handles at spaced locations across the strainer formed integrally with the wall of the strainer for lifting the strainer from the vessel following the infusion process.
For example, the handles may be T-shaped, the leg of the T being formed integrally with the wall of the strainer and the cross piece of the T providing the handle to be grasped for lifting the strainer from the vessel.
In any of the above arrangements, the strainer may be tapered towards its bottom end to fit in a drinking vessel which reduces in cross section towards the bottom of the vessel.
Also in any of the above arrangements, the strainer may be formed from a folded sheet of flexible porous material, the blank providing two side walls, the side edges of which are bonded together to form an open topped receptacle for the particulate material and liquid for infusion with the particulate material.
In a specific arrangement according to the invention the strainer is generally frusto-conical in shape tapering towards its bottom end.
According to a further feature of the invention the wall of the strainer may have a multiplicity of spaced outlets having flap valves which close the outlets when the wall of the strainer is in contact with the wall of the vessel during the infusion process and which open automatically when the strainer is lifted out of the vessel to release the infused liquid from the strainer into the vessel.
In the latter arrangements the flap controlled outlets are formed by a multiplicity of U-shaped slits in the wall of the strainer to create the outlets and flaps controlling the outlets.
The following is a description of some specific
embodiments of the invention, reference being made to the accompanying drawings in which: Figure 1 is an elevation view of a strainer for infusion of a tea or other herbal drink or in a cup formed from a folded blank of a suitable porous paper of sufficient wet strength; Figure 2 is a view of a blank from which the strainer is formed prior to folding; Figure 3 is a perspective view of the strainer showing the upper end of the strainer being opened to receive a supply of tea for infusion; Figure 4 is a perspective view of a cup or mug with the strainer in situ for infusion of a drink; Figure 5 illustrates the withdrawal of the strainer and residual particular material from the cup or mug following infusion; Figure 6 is a similar view to Figure 1 showing the modified form of the strainer; and Figure 7 is a similar view to Figure 5 showing the withdrawal of the modified form of strainer from the cup.
Referring firstly to Figure 1 of the drawings, there is shown a strainer for infusion of a beverage in a drinking vessel. The strainer is formed from a porous sheet material and comprises a pair of walls 10 having upper ends 11, side edges 12 and a bottom edge 13.
The strainer is formed from a blank providing two side walls joined base to base by a fold line. The blank is formed from sheet material such as a thin paper of the type typically used for teabags and has sufficient wet strength to enable the strainer to be lifted from a cup or mug with the residual leaves in the strainer for disposal.
The side walls 10 are tapered towards the bottom fold line so that when the side walls are folded together and the side edges are adhered or bonded together a receptacle is formed for receiving tea or other herbal particulate material from which a drink can be infused.
The upper edges of the side walls are unattached and each side wall has an upstanding T-shaped handle 16. The handles can be grasped by the user to separate the side walls at the upper end of the strainer as illustrated in Figure 3 to receive a supply of tea or other herbal particulate material from which a drink is to be infused.
The strainer is dimensioned to fit inside the mug with the side walls of the strainer supported by the wall of the mug and the handles of the strainer draped over the rim of the mug. Boiling or hot water is poured into the strainer for infusion with the tea or other particulate material in the strainer. After a suitable period has lapsed, the handles are brought together and used to lift the strainer from the mug as illustrated in Figure 5 with the liquid in the strainer issuing through the pores of the strainer walls whilst the residue of the tea or other particulate material is retained in the strainer to leave a freshly infused drink for consumption.
As indicated above the strainer is formed from a porous paper similar to the paper used for conventional teabags and is intended to be disposable.
The handles of the strainer can be embossed or printed with decorative material and/or product information.
Figures 6 and 7 show an alternative construction in which the side walls of the strainer are formed with a multiplicity of slits 18 which may be Ushaped, S-shaped or of tear-drop shaped slits in the side walls through which the liquid can be released from the strainer when the strainer is lifted from the mug as shown in Figure 7.
