摘要： Biaxially oriented tubular articles which are destined to provide bodies for processable food containers are made from an elongate tube of thermoplastics material as it emerges from an extruder. The manufacturing process comprises repeatedly performing a cycle of operations each including the following steps:engaging the tube by a first clamping means (11,12) over a first region at a leading end of the tube (10) and by a second clamping means (13,14) over a second region at a spacing from the first region, so as to define between the clamping regions a portion of the tube to be longitudinally stretched and radially expanded;moving the clamping means apart to stretch the tube portion longitudinally and admitting pressure fluid to the tube portion to expand it radially, such stretching and expansion forming a bubble (100) of biaxially oriented thermoplastics material adjacent the leading end of the tube; andsevering (at 22) at least a substantial part of the bubble from the tube to form the tube with a new end as the said leading end of the tube for the succeeding cycle of operations.

摘要： A process of forming biaxially oriented tubular articles by repeatedly performing a cycle of operations which includes engaging a thermoplastic tube by a first clamping member over a first region at a trailing end of the tube and engaging the tube by a second clamping mechanism over a second region at a spacing from the first region so as to define between the clamping mechanisms a portion of the tube to be longitudinally stretched and radially expanded; moving the clamping mechanisms apart to stretch the tube portion therebetween longitudinally; admitting pressure fluid into the tube portion to expand it radially and form a biaxially oriented bubble adjacent the leading end of the tube, and severing a substantial part, but not all, of the bubble from the tube to form the tube with a radially outwardly flared end as the leading end of the tube for the succeeding cycle of operations.

摘要： A baby feeding pack comprises a pouch-like bag for containing a liquid infant food or drink having walls of flexible sheet plastics material and a gusset, also of a flexible plastics sheet material, sealed to the walls and carrying a teat with a removable closure. The gusset defines part of a sealed auxiliary compartment in which the teat is disposed and protected from contamination and which is closed by a top seal between the walls or between the upper margins of a sheet which also forms the gusset. On opening the auxiliary compartment along a severance line, the gusset can be inverted to form a frustoconical projection by which the teat is presented for access for feeding.
