Abstract: A container for foodstuffs and beverages comprising a vessel having a mouth surrounded by a rim presenting an upper surface of plastics material, and a lid, comprising a diaphragm secured by an endless weld to the upper surface and covering the mouth. The diaphragm has a perforation consisting of at least one through hole and a peel strip sealingly but peelably secured over the perforation. The peel strip has a pull tab formed by a portion of the peel strip folded back on itself and situated outside the perforation. Further, the peel strip has a transverse cut across part of its width at the junction of the pull tab with the remainder of the peel strip on the side of the pull tab remote from the perforation.

Abstract: A method of making a succession of food or beverage containers each comprising a vessel having a mouth surrounded by a rim presenting an upper surface of plastics material. The method comprises filling each vessel in turn and feeding over the vessel a continuous composite web of lidding material produced by forming spaced apart perforations, each comprising at least one through hole, in a continuous first web of diaphragm material having a plastics surface weldable to the vessel rim. The method also comprises forming spaced apart pull tabs in a continuous second web of peel strip material by folding each of a succession of portions of the second web against itself to form each pull tab and subsequently applying and peelably securing the second web which is narrower than the first web to the first web so as to obturate the perforations such that one pull tab is situated adjacent each perforation and remains secured to the second web only at a junction on its one end.

Abstract: A cargo lock for aircraft cargo loading such as a pallet, designed for optional tension release, in which a detent and toggle detent are mounted for independent pivotal movement relative to a fixed mount and are connected together by a sheer pin for movement of the detent to cargo release position while the toggle detent remains in locked position. When locked, an over-center toggle device prevents releasing movement of the pivoted toggle detent, and a positive locking cam retains the toggle device in locking position. Step-by-step release is provided for a series of lock units upon incremental movement of an elongated control rod.
