PROCESS FOR PRODUCING A CASE FOR RECEIVING A WATCHWORK

METHODE DE PRODUCTION D'UN BOITIER DESTINE A RECEVOIR LE MOUVEMENT D'UNE MONTRE

English Abstract

Abstract
A process for producing a case for receiving a
watchwork made from a disposable metallic container is
proposed. In this, the used container is deformed in its
longitudinal axis and, if appropriate, in the radial
direction. A recess for introducing the watchwork is
likewise provided by reshaping.
The case described is economical to produce since
it does without raw materials which have to be prepared
specially.

Patent Claims
1. A process for producing a case for receiving a
watchwork made from a disposable metal container, defined
by the following process steps:
- compressing the container along its longitudinal
axis and, if appropriate, in the radial direction to
a predetermined dimension,
- shaping out a cavity for receiving the watchwork,
- shaping out or forming on a fastening member for
connection to the watchwork.
2. The process as claimed in claim 1, wherein the
container is a can, especially a beverage can.
3. The process as claimed in claim 1, wherein the
metallic material is aluminum, tinplate or the like.
4. The process as claimed in claim 1, wherein the
cavity for receiving the watchwork is coated.
5. The process as claimed in claim 1, wherein the
fastening member is designed as a bayonet fastening.
6. The process as claimed in claim 1, wherein an
integrated mounting for securing the wrist strap is
formed.
7. The process as claimed in claims 1 to 6, wherein
the case formed is provided with a coating.
8. A case for a watchwork produced by the process as

P~oce,as ox ~rod~çlna ~ for receivinq ~ watchwork
~ he pre,~ent Lnvention relate,s to a proce~s for
p~oducing a caise fo~ receiving a watchwork. .
Various proce~ses for producing wat~h case~ from
mst~l, plaatic, wood, ~h~ll material, etc. are kn~wn.
Tho eet ob~e~t ef thc present in~ention i~ to 1: :
p~duce, by re~haping., a new article ready for u,~e from ' 'i
a spent commodity, ;ln parti~ r a used disposa~le
contBinor ~ade o~ me~llio ~at~rlal ~nd ~hus ~o reduce
Qnviromen~al pollution.
Thi~ obJect according to the invention
Açh~v-~ by means of the follo~ing process step~:
- compressing the container along i~s longitudinal
axls and, lf appr~priate, in the radial direc~ion to
a pre~et~rmined dlmension,
- ~haping out a cavity for recei~ing the wa~chwork,
~haping out or forming on a fastening member ~or
cennectlon to the watchwork.
Fu~ther adva~tageou~ ~mbodiments ~merge from ~he
depend~nt claLm~.

The case, made by th~ proce~ accordin~ to the
invention, for receiving a wa~chwork has an initial
material whlch i~ composed ~f basic me~allic materials
and which may, for exa~ple, be a bevera~e can.
The empty can i~ clamped in a tool. Under a
~peci~ic ~orc~ effect, the c~n i~ compre~sed alon~ its
1ongltudinal axLs to a prede~armined dimen~lon.
Slmultaneou~ly with or ~ub~oquently to the ~efvrmation
ta~ing place ~long ~he lon~Ltudinal axis of the can, the
shape may addltionslly also be ~e~uced radially.
~ he case core thu~ ~btdined is further ~haped by
forming a r~cess or a depression Io~ receivlng a
watch~ork. i`
At least one f~stening member is provided fo~ l
flxing the watchwork to the shaped ca~e part. It i~
po001ble to design a bayonet fastening. ~ut other
f~l~ten~ ng members or aat~nln51 element~ can ali30 b6l i
p~ovlded.
9etwe~n th~ watchwork and the case there can b~
a coat~ng. Thie can ~erve for ineulatLon between the
watchwork and case and/or for better adhesion between
these part~.
By means of ~ ~urther Yh~plng operati~n, an
integ~ated mounting for securing ~ wrl~t ~trap con be
made in the c~se-
The advantage o~ the proposed ~roduction of aca~e i~, in addition to the attr~ctive ~ppearance, the
reutili~ation of increaiaingly expen~ive ~aw ~a~erial.

Wa~ch ca~es made in the way according Qo t~e3
invention are economical to produce and do without raw
ma'cerials which have to b~a prepared 6pecially.
