1 Claim. '(Cl. 215-70)
My present invention relates to that general
class of devices which are employed as closures
for receptacles of various types'and, more spe
ci?cally, to a quick-acting closure for tubes,
bottles, and the like.
‘There is an ever increasing demand for a
closure to be used on containers for cosmetics,
dentifrices and materials of general use, either in
the form of liquids, pastes, or powders which, be
10 cause of the frequent use of the same, requires a
closure which will fully seal the contents, prevent
spilling and which can be opened easily with full
assurance that the closing device will not become
lost. It is to supply a device to meetthese recog
nized needs that I have ‘created my quickmacting
My present inventionyfollow’s to a degree the
general design of my receptacle closure shown in
my United States Letters Patent Number 1,715,
452. In my present construction, however, I
have overcome certain de?ciencies of my former
closure. I have provided means that will assure
its more satisfactory operation; means which will
assure against any possible losing of the closure
25 device and which because of its present construc
tion will lend itself more readily to a wider ?eld
of use in that it can be very economically manué
factured in quantity.
Other and more speci?c objects will be appar
30 ent from the following description taken in con
nection with the accompanying drawings, where
Figure l is an elevationof my closure of a type
that might be used quite generally as a closure
35 for bottles, collapsible tubes, or any other similar
collapsible tube such as used for toothpaste, shav
, ing cream, cosmetic preparations and the like.
Figure 10 is a perspective View showing the
convenient manner in which my closure may be
used as on a powder can, or bottle containing

liquid, illustrating how the material can be
shaken, or poured, fromv the container without
in any way having the closure device interfere
with the operation.
- Figure 11 is a cross-sectional View through the
collar used with my device illustrating more com
pletelythe difference in depth of the securing
grooves which accomplish a very de?nite purpose
in my present design.
Referring to the drawings‘, throughout which '
like reference characters'indicate like parts, [4
designates the usual reduced, neck portion as is
common. with many types of containers such as
collapsible tubes, bottles and the like. Into this‘
neck I provide, preferably, two oppositely dis 20
posed threads, or grooves, as It and I1. These
threads as distinguished from those formerly
used as disclosed in my Patent 1,715,452 do not
extend to the end of the neck portion but stop
somewhat short of the end after. the ‘showing, -
particularly of Figures 5 and 8. These threads 25
are molded, or otherwise formed, as grooves hav
ing, ' preferably, uniform depth throughout.
Disposed between the ends of the threads or
grooves thus provided and the extreme end of
neck portion are cam guideways l9 and 20. 30
These have at the faceof neck I4, substantially
the same depth’ as threads‘ I6 and H, but as they
approach the end of the threads they taper to
ward the periphery of the neck and entirely run
out before they meet the end of the thread. 35

The outer surface of collar 22
may take any desired shape. It has, however,
been found most desirable to-provide it with two
opposite, parallel ‘sides as-24 and 25. These sides
are pierced with openings'26 and 21 whose axes
are'coaxially aligned. ‘ Disposed in a plane nor
mal toIthe longitudinal axis are securing grooves
29 and30. These are to accommodate bail mem
ber 32. In the same Vertical plane of openings 26
and Hand parallel-to the longitudinal axis of
collar 22, I provide ‘additional grooves 34 and 35.
'Ihese-grooves'run‘from openings 26 and 21, up

as in the case of grooves 29 and 30, they also are
made .to accommodate bail member 32. One
feature that greatly in?uences the operation of
my closure is the fact that grooves 34 and 35 are

As observedin Figures 2, 3 and 6 it will be no

cap 43 I provide a sealing gasket 42. This may structure shown in my Patent Number 1,715,452. 10
materials. Secured to cap 40 is bail member 32.
The exact manner of securing the two? together
will be largely indicated by the conditions under
15 which the device is to be used.
It is desirable.
particularly for closures wherein neck I4 is small,
to have bail 32 so secured to‘ cap 40 that the
entire cap, and hail, as a unit will pivot about the
inturned ends of bail 32 as 44 and 45. It will
20 be‘ understood itis believed that if large closures
are to be accommodated it might be desirable to»
have caps 43 pivot upon the straight bar 4''! of
bail 32 to the end that collar 22 would not have to
be moved so far up the neck in order to make it
25 possible-to swing the cap free of the same.
In Figure 6 I have indicated a modi?ed form of
my present device in which all the described
characteristics of cap 45 are'retained but collar
52 departs to a degree from the form of collar
22 in'that while openings'54 and 55 are col-axially
disposed they are not. in a plane normal to the
axis of neck 14. This arrangement might be'dee
sirable under certain conditions Wh?re it is con
sidered necessary to use a single thread 56 as .dise
35 tinguished from the other form-~ in which- two
threads or grooves are used.
' '
In Figure '7 I have illustrated my‘ closure means
as applied to a tire valve stem 5!). The construc-,
tion of the various-parts, is exactly as described
above and it functions in the identical manner.
40- It
does, however, provide a very convenient means
of closing such a device in a secure manner with
the showing of Figure 3, the whole device can'be
screwed very easily, either upwardly, to release
the cap,,or downwardly to effect a'secure seating.
For normaluse the pitch of thread l5 and I 'I
should be suf?cient so that a half turn of‘ the cap 20
will release it from. neck‘ I4 so that it'may be
swung over into the‘ position indicated in the Fig
ures {1; ‘5, 7 and 10, this position being assured by
having‘detents 4.4. and 45 abut a‘ shoulder at the
upper ends of the threads. When in this posiz 25
tion‘as illustrated speci?cally in Figure 4, the
of detents 4,4 and 45 are, in secure engage
ment with the bottom of the thread and, as illus
trated by the dotted line showing at 58 and 59.
there is’su?icient clearance between the bottom .30
of grooves 29 and 36 and the legs of bail member ‘
32 so that the full force of the inward pressure,
that can be exerted by bail 3.2, can'be applied to
the bottom of grooves. l6 and H, and thus lock
the device in its position of use. In this position 35
the container can be shaken as indicated in Ha
ure 10 or if the container is a tube as indicated
in Figure 9 it may be laid down, and, still the
car will not creep upon'the thread’ so that when
it is swung hack into! axial alignment thereiwill 4.0
be no interference between the cap and neck’ I4.‘

Method of operation ‘ ’
Assuming that the various parts of my device
have been constructed along the lines‘ indicated,
the ?rst operation in the use of the cap‘ will be
to assemble the closure as a unit} To do this the

The toregoine description‘and the accompany~~

preferred embodiment of my invention but it will
be understood that this disclosure is merely illus
trative and that such changes. in the invention
may be made as are fairly within the scope and
spirit Qi the-following claim.
