Improvement with the elements of dry cells and their manufactoring process.
AS AFRICAN AND MALAGASY INDUSTRIAL PROPERTY P. 887 Yaounde (Cameroon) Patent International Patent Classification: 01 no. 00435 hr the O. 00 the m ^ P.I.. THE V * Requested to 16 hr 30 October 1964 01 Mn to the O.A.M.P.I. (G.P. no. 50,518) by the financial anonymous said: Company the stacks Waving, residing in France. Delivered 15 May 1966, published at The present invention is an improvement to elements of dry cells of the type comprising an elec - trode dissolvable or anode, usually cup-shaped cylindrical optionally lined with an envelope of apart - ment metallic or plastic, and containing, with the inter - position of a support electrolyte, a mixture dépola - risant or cathode electrode into which a centrally - copart, usually formed by a pencil of coal surmounted by a metal capsule for pole into a partnership - tif antibodies, the assembly being closed by a cover through which the center electrode and crimped or otherwise joined to the cup or to the outer casing. For obvious reasons, it is often appeared very a demand on such elements means for warranty and need be removed until during the use. Most often, this member warranty consists a simple strip of paper on the bottom of the bowl anode. In its Patent no. 1.103.391,demandé 2 July 1954, for " improvement to cylindrical cells called flare stacks ", the applicant has described a member plastic warranty disposed either on the pole positive, either on the negative pole of the element. In one embodiment according to this Patent no. 1.103.391, the upper part of the element is closed by a plastic lid, with a capsule brass for positive pole and which is embedded during molding in the plastic. The face top of the capsule is covered with a disk very thin plastic forming band - warra eIT, disk joined to the upper face of the cover by fine fasteners are easy to break. The cover and the DIS - that guarantee the central capsule are molded in at the same time. The elements of this construction are particularly advantageous usage and have undergone major contri - ventilated. The very thin disk joined to the lid acts indeed perfectly its role of guaranteed and as an insulator, and it can be removed very easily owing to its fine fasteners are easy to break. However, these elements are not being protected critical because of the complication of their manufacture. As they are in effect, they must absolutely have a brass cap molding embedded in the cover, and is known as a molding operation with an embedded element is always more delicate and more expensive than the same operation without embedded element. The present invention seeks improvements to such elements of dry cells which are essentially characterized in that the cover is integral with fine fasteners which extend along the center electrode projecting from the cover plate for the wheel retaining warranty, which covers the metal capsule independent of the lid. The invention also concerns the method for obtaining the elements thus defined, method which is essentially characterized in that, the element having been assembled in a conventional manner until final closure, it is provided by threading on the center electrode already capped its capsule the cover flexible plastic molded integrally with braces and the disk, after which, when the latter is carried by the capsule, crimp the cover or otherwise joining the bucket or the outer shell. By designing immediately that this method, which avoids the insert molding of the capsule, is particularly simple and economical benefits some, and furthermore, give it an edge of the foregoing, it can be used in both elements down to ordinary dry cells sealed with plastic or metal outer shell. According to the invention, the implementation of the process is even more conveniently by providing at molding slightly flared at the bottom of the hole to be penetrated by the central electrode. Since it is known that this orifice should instead be on the larger part of a diameter slightly 1° improvement to elements of dry cells of the type comprising a soluble electrode or anode, usually cup-shaped cylindrical optionally an outer shell lined with metal or plastic, and containing, with interposition of a support electrolyte, a depolarizing mixture or cathode into which a center electrode, usually formed by a pencil coal surmounted by a cap metal serving as a positive pole, the assembly being closed by a cover through which the central electrode and crimped or otherwise joined to the outer shell or cup, said improvement is essentially characterized in that the cover is integral with fine fasteners which extend along the center electrode projecting from the cover plate for the wheel retaining warranty, which covers the metal capsule independent of the lid. 2° method for obtaining the elements thus defined, method which is essentially characterized in that, the element having been assembled in a conventional manner until final closure, it is provided by threading on the center electrode already capped its capsule the cover flexible plastic molded integrally with braces and the disk, after which, when the latter is carried by the cap, the cap is crimped or otherwise joining the bucket or the outer shell, the lower portion of the hole of the lid having been preferably provided at molding slightly flared.
