The object of my- invention is to provide a
container and closure therefor of simple, durable
and inexpensive construction.
A further object is to provide in combination
5' with a container, a- closure cap which ‘can be
screwed onto or otherwise associated with the
terminal end of the neck of the container, but
when unscrewed will not become disassociated
from the container, this being accomplished
simply by means of a wire, formed u-shape, and
connected with the cap andassociated with the
neck in such manner as to permit rotation and
tipping of the cap; yet the wire is so associated
with the neck that it cannot be slid off the neck.
Still a further object is- to provide retaining
means for the cap of a container which accurate
ly alines the’cap with the container neck when
it is desired to screw the cap on the neck, yet
which permits the cap to fall back to an‘out-of
2 O the-way position without becoming disassociated
from the container after the cap has been re
moved from the threaded terminal end of the
Another object is to provide the wire so formed
25 that a slight swing of the container in the proper
direction will cause the cap to swing into proper
ly» alined position for thereafter screwing it onto
the neck.
Another object is to provide a modi?ed form of
construction in which a‘neck and cap are pro
vided, the neck being separable from a container
of standard construction.
With these andother objects in view, my in
vention consists in the construction, arrangement
35 and combination of the various parts of the de
vice, whereby the objects contemplatedv are at
tained, as hereinafter more fully set forth, point
ed out in my claims, and illustrated in the ac
companying. drawing, in which:
Figure 1 is a front elevation of a container
and closure therefor embodying my invention,
the container in this case being a collapsible tube
for tooth paste or the like, and the cap being
shown in disconnected and tipped-back position.
Figure 2 is a view similar to the upper portion
of Figure 1 showing the cap swung into position
alined with the threads of the neck, Figure 2a
being an enlargement of‘ a portion thereof.
Figure 3 is a similar view showing the cap
50 screwed into sealing position.
, ,
Figures 4- and 5 are sectional views on the lines
4-4 and 5—5 of Figures 1 and 2 respectively‘,
showing the parts on an enlarged scale.
Figure 6 is an enlarged perspective view of a
special shape of wire which I use as a means for
retaining the cap in associatedposition with the
Figure 7 is a view similar to Figure 1 showing
60 the closure applied to a bottle.
Figure '8 is a sectional view on the line 8-8 of
Figure 7; and
Figure 9 is a view similar to Figure 3 showing
the neck ‘of my closure structure separable from
the container.
On the accompanying drawing I have used the
reference numeral Hi to indicate a container
suchas a collapsible tube. It is provided with
an elongated neck l2’ having a threaded terminal
end‘ M, which is enlarged relative to the neck
and thereby provides a shoulder IS.
A cap is illustrated at l8 which may be of the
ordinary screw threaded type provided with. a
gasket or with a cone-like projection 20 to seat
against the inner edge 22 of the neck I! for seal
ing purposes, as shown in section in Figures 2a
and 3.
I provide a retainer A connected with the cap
18 in any'suitable manner. By way of illustra
tion I show the retainer as being provided with
a pair of terminal ends 24 curved to follow a cir
cle and the cap 18 as having an annular groove
26 to receive the terminal ends 24.
The ?ange below the groove 26 is notched as
at 28 for the arm portions 30 of the retainer A to 25
extend through. These portions at their lower
ends have ?nger-like return bends 32 extending
partially around one side of the neck l2, when
the cap is in the positions‘ of Figures 2 and 3.
The retainer wire A has additional portions 34
which are spaced closer together than the por
tions 30, and whichv terminate in a cross bar 36.
The cross bar 36 is curved around the opposite
side of the neck l2. . The portions 34 are substan
tially parallel to each other and spaced a distance
approximately‘ equal'to the diameter of the neck
I2 as shown in Figures 4 and 5. The portions 3|]
are also parallel to each other, but are spaced
apart substantially the diameter of the lower end
of‘ the cap 18.
The retainer A is preferably made of spring
wire so that its arms can be spread apart and
then, the terminal ends 24 permitted to spring
together into the annular groove 26 for thus con
necting the retainer A with the cap. Other 45
means of connection‘, of course, can be provided,
the main requisite being, that the retainer A be
permanently secured to'the cap 18 under normal
My retainer A made in the'form shown‘permits 50
the cap it to be unscrewed from the threads I 4
and then dropped back to the open position shown
in Figure 1. The cross bar 36 and the ?ngers
32 are spaced apart a distance equal to substan
tiallythe diameter of the neck l2, as will be evi
dent from an inspection of» Figure 1, so that‘ tip

I claim as my invention:
1.‘ ‘In adevice of the classdescribed, a container
having a neck, a cap for the terminal end of said

whereupon the cap can be screwed to the sealed

position of Figure 3. The neck ll, of course,‘ is piece of wire formed‘ U-shape, the cross bar there

therefore the wire A retains the cap l8 against .
disassociation from the neck l2.
The wire A may beinexpensively formed, yet
' serves the purpose of eifectively retaining the cap
20 l8 from disassociation from the neck l2, and pro
vides a quick means of alinement of the cap with
the threads on which it is, normally positioned,
which is a decided advantage as it eliminates the
necessity of having to .be particular about getting

the axis of the neck before screwing it into posi
