Tension ring closures ior packing containers
are known in many forms as regards a closure

closures with tension screwv ?xing, eccentricle

These kinds of closure devices are sometimes
' too involved in manipulation ‘but mostly are too
complicated andtherei'ore are very expensive in

Figures 6, 7, and 3 show in elevation, plan and
cross-section a constructional form of the tension
20 ring closure which completely meets all require

openings coincide with the boring 213 provided

has at the projecting end a boring for receiving

The end of one closure member carrying the

ring are so constructed that in the closed posi
tion they take up a shape which makes it pos
sible to ?t on a known securing cap.
The con
struction of the closure members is thereby con
siderably simpli?ed because it becomes unneces
15
sary to provide bushings for apin. This fact,
together with the absence of the sealing parts
or’ the sealing device, causes the cost of manufac
ture to be considerably reduced. While with the
sealing arrangement it is possible that, for exam 20
pic, on account of the damage which may easily
occur or on account of skilful manipulation that
the closure can be opened by unauthorized per_
sons, this danger is completely avoided by a se
curing cap constructed in a known manner. The 25
cap secures the closure parts not only against
undesired and unauthorized opening, but also on
account of the complete enclosing of the engaging
closure means, against accidental damage ‘and
against other undesired external in?uences. The u
closure has a pleasing appearance. The surface
of the cap offers the possibility of applying a
suitable advertisement.
'
In the constructional form according to Figures
14-17 the engagement members I and h are made
semicircular in the upper part so that in the
closed position they form a complete circle. In
order to obtain a suitable abutment for the secur
ing cap m, the closure members (1 and d1 are
o?set in the form It, whereby the semi-circular 60
closing parts f and h are formed. In addition,
the closure parts J‘ and h have an edge 2' at the
height of the parts 2 and h which engage one
over the other in order topbtain a uniformly
thick abutment for the cap m. The edge 2' is in 4:5

A further advantage consists in this, that the

can therefore be detected.

It is obvious that in addition to the construc
tional examples described, further modi?cations
oi the closure members are possible without de
parting from the essence of the invention, which
consists in this, that the closure means have a
suitable shape for receiving a seal cap. In Figure
10 13 for example, it is shown in broken lines that
the closure members I and h can have a polygonal
shape instead of a circular shape. Even with a
