Abstract: A beverage capsule (101), a method of lidding a beverage capsule (101) and a sealing head (115) are disclosed. A capsule body and a lid (110) of the beverage capsule (101) together define an internal volume for containing beverage ingredients. A peripheral flange (105) of the capsule body comprises or consists of a thermoplastic polymer, the peripheral flange prior to sealing with the lid having a flat receiving surface (106). The lid (110) also comprises a thermoplastic polymer. The lid (110) is sealed to the peripheral flange (105) to form a first peripheral seal able to withstand pressurisation of the internal volume during use. The first peripheral seal comprises a weld between the thermoplastic polymer of the capsule body and the thermoplastic polymer of the lid (110). A face of the peripheral flange (105) in contact with the lid (110) comprises a recess formed into the flat receiving surface (106) and the lid (110) is sealed to the peripheral flange (105) within the recess.

Abstract: Disclosed is a resistance welding device (1), especially for welding thermoplastics, which comprises an actuator (2) of elongated shape with a distal end (3) and a proximal end (4), a heating system with a transformer (7), a cooling system and an electronic power supply and control system (6). The actuator (2) has a power supply at its distal end (3) and at its proximal end (4) it has an electrode system (81, 82) terminated by a heating element (9) at the outlet (52) of the cooling system. The heating system with a transformer (7), the cooling system and the electronic power supply and control system (6) are located inside the actuator (2). Additionally, the transformer (7) is connected to the heating element (9).
