Abstract: A flame producing assembly includes a pocket lighter, an extended wand, a rigid support, and a helical spring. The pocket lighter extends along a longitudinal axis and defines a length. The pocket lighter includes a piezoelectric ignition device operable to produce an electric charge. The extended wand is electrically coupled to the piezoelectric ignition device. The rigid support is disposed inside the extended wand and includes a longitudinal inner opening. The helical spring extends along the longitudinal inner opening and protrudes beyond a free end of the rigid support. The free end is opposite a connecting end that is proximate to the pocket lighter.

Abstract: The invention relates to razors and razor blade cartridges and methods of manufacture therefore including at least one razor blade housing made from polymer material and at least one skin contacting surface, the at least one skin contacting surface being made of a superhydrophillic polymer material. The polymer material has surface properties modified by functionalisation. Preferably the polymer material is a TPU or TPE, with a Rockwell hardness D scale between 30 D and 85 D, a tensile strength between 35 and 80 MPA and a flexural modulas between 40 and 2350 MPA The invention also relates to a method of manufacture of a razor blade cartridge including the steps of moulding a cartridge housing including skin contacting surfaces of polymeric material; subsequently activating the skin engaging surfaces of the polymer using either physical or chemical means to make the surface receptive to the covalent grafting of a monomer, and grafting a functional group onto the surface such as an N-vinyl lactam.

Abstract: A manual device extends in an axial direction and includes a housing having a first housing portion and a second housing portion. First and second heads are each axially movable between a use position and a stowed position. The first head is in the stowed position when the second head is in the use position, whereas the second head is in the stowed position when the first head is in the use position. The first head and the second head both are carried by a single carriage movable in the axial direction and arranged inside a barrel. A groove forming a cam track is formed by a first shoulder of the first housing portion and by a second shoulder of the barrel. A lug of the carriage cooperates with the groove.

Abstract: A hand-held device includes a first portion and a second portion. The first portion is engaged at least in part with the second portion while being movable in translation in an axial direction relative to the second portion. The first portion presents a first distal end while the second portion presents a second distal end opposite from the first distal end in the axial direction. A blocking device is configured to prevent the first portion from moving in translation in the axial direction relative to the second portion only when, considered in the gravity direction, the first distal end is arranged above the second distal end. The blocking device includes a chamber and a ball or the equivalent housed in the chamber.
