Abstract

The present invention relates to an infusion packet (51) comprising a top (52), a bottom (53), a first side (54) and a second side (55); wherein the bottom (53) of the packet is defined by a gusset (61) and each side (54, 55) of the packet is defined by a seal that extends between the top (52) and bottom (53) of the packet; the packet (51) being characterised in that the seals defining the sides (54, 55) are arranged such that the packet has a compartment with a substantially trapezoidal cross-section.

Description

technical field [0001] The present invention relates to infusion packets, and methods of producing such packets. In particular, the present invention relates to infusion packages containing infusible material such as tea. Background technique [0002] In the past, conventional infusion packages (eg tea bags) were usually flat and comprised a single chamber filled with infusible material (eg leaf tea, herbal blends). Such packages often contain infusible material sandwiched between square or circular sheets of porous material. Such packaging limits the movement of infusible material within the packaging to essentially two dimensions. Therefore, the brewing performance of such packages is limited. [0003] Dual chamber infusion packages are also known, such as those described in US 2,593,608 (A.G.F. Rambold). In such an infusion pack, the infusible material is contained in two chambers, each connected to the other at the bottom and at the top. Such infusion packs are beli...
