Abstract: Provided is a process for forming a sheet of thermoplastic material into a three-dimensional shape, the process comprising the steps of (i) forming the sheet at a temperature below its glass transition temperature to produce a first formed shape in the sheet, followed by (ii) raising the temperature of the first formed shape (20) to above its glass transition temperature whilst a male former (12), having at least a portion of its profile being substantially the same as that of the first formed shape (20), is positioned to substantially align at least a portion of its profile with that of the first formed shape (20), thereby restricting the first formed shape from shrinking back towards its original sheet form, followed by (iii) further forming the first formed shape (20) at a temperature below that of the glass transition temperature, to form a second formed shape (24), followed by (iv) raising the temperature of the second formed shape (24) to above its glass transition temperature whilst a male former (16),

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.

Abstract: The present invention relates to an infusion packet comprising a single sealed compartment (16), the compartment having a top (8) and a bottom (9) defined by two transverse seals (7) that are separated by a distance D, the distance D being in the range of 40 to 70 mm, wherein the compartment comprises at least one side gusset (15), the side gusset (15) consisting of two gusset panels (12) and three gusset creases (13, 14).
