Abstract: The present invention relates to a method for manufacturing a battery comprising a casing provided with a cup and a closure part for said cup, the method comprising the successive steps consisting in: providing at least three parts with a first part defining one pole, and a second part and a third part defining the other pole and intended to form together the cup, the first and second parts respectively comprising a first surface and a second surface (6a) of matching shape, at least one adhesive portion of each of said surfaces extending in a geometric surface non-parallel to the general axis of the battery; bonding the aforementioned first and second surfaces to provide a structure with an adhesive joint between the first and second parts; welding the third part to the second part; the adhesive joint being arranged against an inner face of the cup, the aforementioned adhesive portion of the second part forming a stop, along the general axis, for the first part, which is located inside the cup.

Abstract: A closing/opening system for a case of a timepiece is defined particularly in first and second parts of the case. The system includes a device for producing a mechanical connection, particularly a bayonet connection between these first and second parts and a device for creating a friction torque between these first and second parts. The device for creating a friction torque includes tightening faces to cooperate with one another when closing/opening the case and which are defined in the first and second parts. The system further includes a tightening element in one of these two tightening faces. The tightening element generates a constant friction torque during a course of travel of one of the two parts relative to the other when closing/opening the case of the timepiece.
