The well known screw cap for containers has
5 long been recognized as being objectionable be
described and is illustrated in the accompanying
drawing in which:

- cause of the fact that the cap is easily lost or " “ Fig-1 .is'a plan view partly broken away;
misplaced, and a good deal of trouble is involved
in removing and replacing the cap. ' A good many
efforts have been made to overcome these objec
10 tions, but most devices for that purpose have not
been practical because they have either not pro
vided an air tight seal or'because the cost has
been‘ prohibitive. Containers'are sold inlarge
'quantities at a small margin of profit, and the
15 , addition of a fraction of a cent to the cost of
manufacture is an important item.
,

~
The object. of my invention is to devise a closure
which‘may bemreadily opened and closed without
removing the cap and which will provide an air
tight closure without the useof washers, and
which maybe manufactured at a cost at or below
the cost of the ordinary screw cap. I attain this
object by forming the exterior of the discharge
and of the container with slots or recessesform
25 ing'shoulders in two opposite vsides adapted to be
engaged by the inturned edges of the ?ange of a
slide. The sides of the discharge end above the
shoulders may be tapered Fso that the slide may
be snapped over the topof the discharge end.
30 The top of the discharge end is preferably slightly
' convex to provide complete and full engagement
, between the cap and the top- or mouth of the
opening. A hole or opening is located in the slide
cap adjacent one end thereof and adapted to
35 register with the opening in the discharge end vof
the container. Other objects of my invention
and other details and modi?cations of my con
structicn will hereinafter appear.

The construction above described has'the fol

move and may cause contortion of the slide which
formed of two parts, I'and lb, the part II’ being
will prevent it from ?tting tightly against the
threaded at its upper end, and the part I‘ having
a circular central opening 5 and being internally 15
threaded at its lower end for threading on the
15 top of the discharge end at all points.
‘
Preferably the top of the discharge end I is
slightly convex in a vertical section taken at
right angles to the grooves 3 and straight in a
vertical section taken parallel to the grooves 3.
20 This slight rounding of the'top permits a more
effective engagement of the slide cap 4 with the
top of the discharge end I. With this construc
tion the height of the ?anges may be substan
tially the same as the distancebetween the shoul
cylindrical and secured to the container v2, and
upper end of the part I". The part IP‘ is other
wise formed in the same general way as the dis
charge end I as illustrated in Figures 1, 2, and 3;’
being substantially square’ in horizontal cross- 20'
section.
Instead of a slot 3 forming shoulders
for engagement by the inturned edges 41’ of the
slide cap 4, a recess, 3' is formed in opposite
sides of the part Ia, forming shoulders for en
25. ders and the top, the tension being caused by ‘ gagement by the said inturned edges 4“, 4b.v
.hiihe rounding or convexity of the top.
The opening 5 in the discharge end I is prefer
ably round in horizontal section, and at one
end of the slide cap 4 is an opening 6, which may,
80 be the same shape as the opening 5 in the dis
charge e?d I, and which is‘ adapted to register
with said opening 5‘ in one position of-the slide
cap-4. The opening 6 may be smaller and of
any desired shape, as illustrated in Fig. 10' or
Fig. 11, so that the contents may be expressed as
a ribbon of any desired shape, inthe case of
paste. The opening 6 may be merely in the form
of a recess, as illustrated‘inFig. 12.
At the ends of the-slide cap 4 are lugs ‘I, ‘I
which are'adapted to engage the discharge end
I to prevent the .slide from being removed. The
lugs. ‘I, ‘I may depend from the top of the‘slide 4
as illustrated in Fig. 2,, or may be turned in

Although theslide cap 4 will be pressed ?rmly
upon'the top of the discharge end I under com
pression by the ?anges 4“, _so that there will’ be -
a frictional engagement and the slide will not
move unless force is applied thereto, as an addi- 30
tional‘ precaution against movement of the slide
while the article is in transit before it is used,
the hole 6' may be only partly punched out as
illustrated in Figs. 7 and 8, leaving a‘disk of
metal 8 in the opening.- This is punched below '35
the lower surface of the slide 4" so that it wwill
engage the’ top of the discharge end I_ when .the
slide is moved, and at one edge of the disk 8 a
lip 8“ is raised slightly above‘the upper surface
of the slidev 4,” so that a-flnger nail, pin or other 40
pointed article may be inserted beneath the said
lip to remove the disk 8 when it is desired to
use the device.

discharge end I causes the ?anges 4‘; 4' of ‘the
slide cap *4 \to be pressed outwardly until the

distance between the upper 'edges or shoulders
