ASH TRAY
Abstract
An ash tray comprising an inner cup-shaped receptacle surrounded
by an outer cup-shaped receptacle. Both receptacles have an upper
smooth edge so that a cigarette can rest on the two edges; the
upper edge of the inner receptacle is lower than that of the outer
receptacle, so that a line tangent to the two edges is inclined to
the horizontal at an angle lying between 10.degree. and 40.degree..
The distance from the upper edge of the inner receptacle to the
opposite wall of the inner receptacle (as measured along an
extension of the line tangent to both edges) is between one-eight
and one-half the length of a cigarette, and the distance between
the two edges on the same line of tangency is between one-half and
full length of a cigarette minus the distance from the upper edge
of the inner receptacle to the opposite wall of the inner
receptacle. The inner receptacle may be circular with a downwardly
and inwardly sloping inner surface and a downwardly and outwardly
inclined outer surface. The outer receptacle has a downwardly and
inwardly sloping wall.

Claims
I claim:
1. An ash tray comprising two concentric cup-shaped portions, an
inner cup and an outer cup, both cups having an upper edge, the
upper edge of said inner cup being lower than that of the outer cup
so that a line tangent to all segments of the contours of the two
edges, on which a cigarette would rest, is inclined to the
horizontal at an angle lying between 10.degree. and 40.degree.,
both said edges being smoothly rounded, so that a cigarette can
slide downwardly and inwardly into said inner cup as it shrinks by
burning, said outer cup having a downwardly and inwardly sloping
wall, and said inner cup having a downwardly and inwardly sloping
inner surface and a downwardly and outwardly sloping outer wall
that meets said wall of said outer cup at a vertex that lies along
a horizontal plane, a cone in said inner cup projecting up from the
bottom thereof to a point, the top of said cone lying below the
line tangent to said two upper edges.
2. The ash tray of claim 1 wherein the said cone meets said
downwardly and inwardly sloping inner surface at a circular vertex.
Description
This invention relates to an improved ash tray, and, especially
though not exclusively, to an ash tray of the disposable type.
Traditional designs for ash trays provide a dish having one or more
notches or smooth arcuate recesses around the periphery, in which
the cigarettes are to be rested. Since such ash receptacles become
very dirty and provide a distasteful task in cleaning, one object
of the present invention is to provide an ash tray which, instead
of requiring cleaning, can be easily disposed of at low total
expense.
One of the problems with providing a proper ash receptacle for
cigarettes has been that a cigarette burning in a predominately
vertical position builds up tars within it and this action causes
it to smell. The present invention overcomes this by holding the
cigarette in a predominately horizontal position.
An even more important object of the invention is to provide a
disposable ash tray having a novel protective feature that makes it
substantially impossible for a cigarette placed in the receptacle
to fall out of the receptacle even though it may burn completely to
an end. A major purpose of this structure is to reduce the
likelihood of fires. For example, when a smoker leaves a cigarette
burning in an ash tray, and falls asleep, conventional ash trays
may not provide any really certain means of preventing the
cigarette from becoming unbalanced and falling out of the tray.
Even though the smoker may have appropriately placed his cigarette
in a conventional ash tray, lighted end in, and has rested it in a
peripheral notch or recess, it tends to burn until its length has
been so shortened that the cigarette becomes unbalanced, with a
major portion of the cigarette outside the ash tray. When so
unbalanced, the cigarette falls out of the ash tray, unless someone
picks it up and snuffs it out beforehand; and, of course, if a lone
user has fallen asleep in the meantime, there is no one to do
this.
There is currently on the market a type of ash tray, sometimes made
of an injection-molded plastic and sometimes made of ceramic,
having sharp V-grooves or narrow U-grooves in the edge of the bowl.
These grooves are purposely made to be slightly smaller than
cigarette diameter. For proper operation the smoker presses his
cigarette into the grooves, thereby compressing the tobacco and
helping to exclude oxygen from the cigarette in areas where it is
in contact with the inside wall of the groove. When the cigarette
is properly pushed into such a groove, it will burn only so far as
that groove, and will there become extinguished because of
insufficient oxygen exposure. The trouble with this structure has
been the human element, for smokers have sometimes carelessly
placed the cigarette improperly into the groove--or failed to press
it down far enough--so that it can still fall out when it is burned
a while and the lengths on each side of the groove have become
unbalanced. Unfortunately, improper use of such ash trays has often
resulted in considerable fire damage.
Another object of the present invention is to provide ash
receptacles which are compactly stackable within each other, thus
enabling a large number to be handled in a small space. For
example, when they are used on a restaurant table, a stack of the
ash trays of this invention may be placed on the table, and when
the waiter changes tables, instead of dumping out the ash tray, he
may simply remove the top tray, leaving the remainder.
Briefly summarized, the ash tray of this invention comprises a
receptacle made from thin material which is not inflammable. A
receptacle of this invention is so contoured that the cigarette of
necessity rests in it and burns normally, and while burning, the
cigarette creeps into the dish, and if left unattended, falls
inside the dish. The ash tray is so contoured as to provide an
inner ring and an outer ring. The inner ring surrounds an inner or
central dish, and the outer ring surrounds an outer dish, or
circular channel between the inner dish and the outer channel. The
positioning of the rings with respect to each other is properly
dimensioned and proportioned, and there is also an important
angular relationship. These will be explained in the following
description of several preferred embodiments. Other objects and
advantages will also appear from this description.

25 but slightly modified.
The ash tray 30 shown in FIGS. 1 through 9, as well as the other
ash trays shown, may be made from noninflammable paper such as
metal-foil-backed paper or film-laminated paper. Any nonflammable
stiff paper may be used, including some of the clay-finish papers.
Also, plastic such as phenolic and melamines and ceramic materials
are appropriate, though ceramic ash trays will not stack quite as
compactly; nevertheless, as far as design is concerned, the ash
tray can be made in ceramic with good results. The ash tray may be
made from a flat paper blank or a flat plastic blank or may be made
by vacuum molding or injection molding, or can be made by stamping
and forming metal. It may have a vacuum metalized surface for heat
reflection or it may be otherwise coated.
The ash tray 30 of FIGS. 1 through 9, whether made from a
paper-metal foil laminate like the blank in FIG. 8 or of molded
plastic, or in any form, comprises a unitary receptacle providing
two concentric cups, a lower, inner cup 31 and a higher, outer cup
32. The outer cup 32 has a peripheral edge 33 higher than the
peripheral edge 34 of the inner cup 31 and its wall 35 meets the
inner cup 31 by means of a web 36 which extends up from a vertex 37
where the wall 35 of the outer cup terminates; the web 36 extends
up to the upper edge 33 of the inner cup 31. The vertex 37 forms a
circle.
The inner cup 31 has a sloping inner wall 38 that goes down to a
bottom vertex 39 forming a circle on the same plane as the vertex
37. From the vertex 39 a central cone 40 may arise, terminating in
a point 41. Preferably, the cone 40 is made so that it lies fully
below a line passing through or tangent to the edges 33 and 34 and
extended on down. Hence, the cigarette C never rests on the top 41
of the cone 40. When it burns short, the cigarette C may rest on
the slope of the cone 40, as will be explained later.
The outer periphery 33 is preferably provided with V notches 42
which are the preferred cigarette resting locations. As shown best
in FIGS. 2 and 3, the cigarette C, in at least its early stages of
burning, rests tangent to the edge 33 in a notch 42 of the outer
cup 32, on or tangent to the edge 34 of the inner cup 31, and on
the opposite slope 38 at a stop position.
In FIG. 6, the material of the ash tray is shown here as
foil-coated paper, comprising a lamination 43 of foil on the inside
surface and a lamination 44 of paper on the outside. At the notches
42, are downward folds 53 (see FIG. 8) which provide smooth tangent
resting points and eliminated the change of the cigarette's
catching on a sharp paper edge which might prevent it from sliding.
The tangent resting points are located about where the fold is
made. This tangency is best shown in FIG. 6.
The dimensions and angles involved are important. The dimension A
shown in FIG. 4 is the distance from the edge 34 to the opposite
stop point on the wall 38, measured along the line which is an
extension of the line joining the tangents to the edges 33 and 34,
and the distance along that line between the edges 33 and 34 is the
dimension B shown in FIG. 4. The dimension A is ideally 0.3 times
the length of a new cigarette, which for current standard sizes is
1.3 inches or 33 mm. The maximum length for dimension A is about
one half the length of a new unlit cigarette or about 2 inches (50
mm.) and the minimum is about one-eighth the length of a new
cigarette or about one half inch (about 12 mm.). The dimension B is
ideally about 1.4 inches (35 mm.) or slightly larger than the ideal
length of the dimension A. The maximum practicable length of the
dimension B is the length of a new unlit cigarette, less the
dimension A, or about seven-eighths the length of a new cigarette
when A is at its minimum, i.e., about 31/2 inches (about 88 mm.).
The minimum length of dimension B is half of the length of a new
unlit cigarette, less the dimension A, or about one-eighth the
length of a new cigarette (about one-half inch or 12 mm.). The
cigarette slope angle in this invention lies between 10.degree. and
40.degree., ideally around 25.degree., and this being the
inclination to horizontal made by the line tangent to the edges 33
and 34, horizontal being the plane of the circles 37 and 39.
When these critical dimensions and angles are used, one very
important result is illustrated by FIGS. 3, 4, and 5. As shown in
FIGS. 1-3, a cigarette C has just been lit, and it is placed
somewhere along its length on the edges 33 and 34. The slope is
such that the cigarette C automatically slides until its lighted
end D engages the wall 38. At this time, the unlit end E is still
overhanging the outside of the ash tray 30, and if nothing else
happened, the cigarette C might burn up to a point near the edge 33
where the weight of the unlit overhanging portion F (see FIGS. 6
and 3) would outweigh the inside portion, and the butt could then
fall over out of the ash tray 30. However, this cannot happen,
because a cigarette shrinks as it burns, and because the angle of
inclination tends to cause it to slide further into the ash tray
30. It slides freely across the rounded edges 33 and 34. The
shrinkage pulls the unlit end E into a safe position as is shown in
FIG. 4, and upon further burning the ash G gives way and falls to
the bottom 39 of the inner cup 31 and the cigarette C then slides
down further to a position such as that shown in FIG. 5. It will do
this also if the smoker has taken some draughts on it and has
replaced it on the edges 33 and 34, because the lighted end will
again immediately slide against the wall 38. The proportioning on
the positions of the edges and the angle of rest of the cigarette
is such as to make it virtually impossible to misuse the ash tray
30, or to misuse cigarettes in relation to it. A cigarette always
falls or slides into a safe position.
As shown in FIGS. 6 and 7, another feature of the invention is that
the lip structure 33 is curved down between the notches 42 so that
there are no sharp edges to hook on to the cigarette C and impede
its proper sliding in. There is a smooth curve at the contact
points rather than anything confining, as is shown in FIGS. 6 and
7.
Note that when the cigarette burns in the way shown in FIG. 5, it
does not rest on the vertex 41 of the cone 40 but falls beside it
on to the sloping wall of the cone 40. The cone's function is to
hold the lighted end up somewhat so that the air can circulate
underneath it and keep the cigarette burning even when the
cigarette is short, so that it can still be smoked until it is
finally too short. As shown in FIGS. 5 and 9, a very short
cigarette stub will then rest on three points, on the inner rim 34
and on both of the two sloping surfaces 38 and 40.
A blank 50 shown in FIG. 8 may be used to manufacture the ash tray
30 of FIGS. 1 through 7. It will be seen that the blank comprises
an arcuate edge 51, having short cuts 52 to provide the notches 42
when flaps 53 are folded down. There are arcuate fold lines 54, 55,
and 56 to provide the vertices 37, 34, and 39, respectively. The
two radially inwardly extending edges 57 and 58 are brought
together during folding, and a marginal portion 59 along one of
these edges 58 may be previously provided with adhesive, or
adhesive may be applied just previous to the folding operation.
An outstanding feature of the invention when it is made of thin
material such as foil-coated paper, is its stackability. It can be
stacked just as compactly as thin paper plates or cups, and FIG. 9
shows a short stack of these ash trays 30a, 30b, and 30c, with
other reference numerals corresponding with the indicia a, b, and c
added for the thin trays. Since they stack so compactly, an entire
stack may be used as an ash tray, and the top one removed as it is
dirtied. There can be successive such removals until finally the
stack is consumed.
The number of slots 52 which are on the periphery is not critical.
The amount shown in the drawing is chosen to give a satisfying look
and good performance, but more or fewer can be used.
A modified ash tray 60 of the invention is shown in FIG. 10, and
FIG. 11 shows a pattern 61 for it, generally circular with radial
cuts 62a somewhat resembling a flattened orange peel. There are
provided circular fold lines 62, 63, and 64 to make the inner and
outer cups 65 and 66. In a preferred form of the ash tray 60, there
is gluing at a tab 67 on the edge of each of the several segments
68. At the outer edge, flaps 69 are turned down with a wide curving
fold provided. The result, as shown in FIG. 10, is very similar to
what was shown in FIGS. 1 through 8.
In this instance, there is no central cone, and the inside of the
inner cup 65 is made with a flat bottom surface 70. The upper edges
72 and 71 of the outer and inner cups 66 and 65, respectively, are
smooth and the edge 71 is broadly rounded at the notches 73, which
are again provided with the downward folds 69 located so as to
provide smooth tangent resting points and to eliminate the chance
of a cigarette's catching on a sharp paper edge. The wall 74 of the
outer cup 66 and the walls 75 and 76 of the inner cup 65 slope
conically. The cigarette rests on tangent points inboard from a
curved-away sharp outer edge 77, when it is rested in one of the
notch areas, and again of course rests on the smooth folded edge 71
of the inner cup 65, which is lower than the edge 72 of the outer
cup 66. It may also rest substantially against the conical wall 76
of the inner cup 65. The same proportions are used as those
discussed above in connection with FIG. 4, for these proportions
and slope angles apply throughout the invention. Note that the edge
71 of the inner cup 65 is (as throughout this invention it must be)
lower than the edge 72 of the outer cup 66.
Another modified ash tray 80 of the invention is shown in FIGS. 12
through 14. Here the blank 81 (FIG. 14) comprises a full circle,
with an outer edge 82 having recessed arcs 83 therein alternating
with the normal edge 82 at regular intervals about half the width
of the full length portions 82. Each full length portion 82 has a
notch 84 enabling the folding of flaps 85 to give the needed smooth
edge here. There are no radial cuts as in FIGS. 10 and 11, but
there are radial fold lines 86 and 87 and also fold lines 88 and 89
to give overlaps, much as is done in some types of paper cups. The
result is quite attractive, as shown in FIGS. 12 and 13. There are
also two generally circular folds 90 and 91, which are made up of
short straight folds that lie at an angle to each other, fold lines
92 and 93 for the outer fold 90 and fold lines 94 and 95 for the
inner fold 91.
The relationship in this ash tray 80 between its inner cup 96 and
outer cup 97 is substantially the same, although in this instance
there is a zig-zag, star-like rim 98, 99 on each of the inner cup
96 and outer cup 97, which serves for holding the cigarette, again
without causing any catching at any of the edges, since they are
all folded edges.
Other forms along this line are obviously possible, and it is not
critical that the device be made from a flat blank, for it can be
molded or pressed as has been stated before.
For example, FIG. 15 shows a square ash tray 100 having a square
outer cup 101 with a vertical wall 102 connected by a flat bottom
wall 103 to a square inner cup 104 having a vertical wall 105
extending up from the flat bottom wall 103. The proportions, slope
angles, sizes, and rounding of edges 106 on the outer wall 102 and
107 on the inner wall 105 are basically as have been discussed. The
walls 105 and 103 or either of them may be made with a slope,
especially the inner wall 105. There may be a central pyramid like
the cone 40 if desired. Instead of being square or circular, the
ash tray may be rectangular or in the shape of a regular or
irregular polygon or an ellipse or irregular closed curve. The
irregular shapes are easier in ceramic or molded plastic.
The embodiment of the invention shown in FIGS. 16, 17 and 18
presents an ash tray 110 made much like the type of cups that are
used in many restaurants to serve cole slaw. This ash tray 110 may
be considered as a totally folded embodiment. It may be made from
metal, like the pie plates used in frozen foods. Once again, it has
an outer cup 111 and an inner cup 112, through in this case the
outer cup 111 is provided with a flange 113 around a conical wall
114, the two meeting at a point 115 where curvature changes, not in
a sharp edge but at a rounded vertex. The downward sloped wall 114
joins an upwardly sloped conical wall 116 of the inner cup 112 at a
vertex 117 which describes a circle around the bottom of the cup
112. The inner cup 112 also has a smooth upper edge 118 and an
inner sloping conical wall 119 leading down to a circular flat
portion 120.
The blank 121 of FIG. 18 is circular and is provided with a
circular outer circumference 122, with circular fold lines 123,
124, 125 and 128, and with radial fold lines 126 and 127 in pairs.
There is no need to have the notches here because of the folds
along the double fold line 126, 127, so that a cigarette C rests on
the smooth edges 115 and 118 without any sharp cut paper edges. A
wedge-shaped space 128 (FIG. 17) minimizes the cigarette contact
along the flange 113, and there are smooth contact points providing
minimum obstruction to the cigarette's natural tendency to slide,
so that as it burns, the cigarette C does slide inwardly toward the
inner cup wall 119 opposite from the edge 118 on which it
rests.
As stated earlier, the cup may be molded instead of made by folding
or by forming a flat blank. A molded cup 150 is shown in FIGS. 19
through 23. It may be pressed instead of molded, if desired, so
that it may be made out of suitable sheet material, such as metal,
or it may be made from phenolic resin or from other types of
fire-resistant plastic. The ash tray 150 has an outer cup 151 and
an inner cup 152, and the outer cup 151 has a sloping outer wall
153 meeting a sloping flange 154 at a smoothly curved inner rim
155. The downwardly and inwardly extending conical wall 153 meets
an outer conical wall 156 of the inner cup 152 at a vertex circle
157. The inner cup 152 has a smooth contact edge 158 lower than the
flange 154 and rim 155, and it has an inner conical wall 159
leading to a well 160 with a flat bottom wall 161, which is
coplanar with the circular vertex 157. The edge 158 is smooth, so
that it does not make a sharp contact with the cigarette C. The
slope angle of the cigarette again is within the range of
15.degree. to 40.degree. and is preferably about 25.degree. so that
the cigarette C has a minimum sliding resistance and does not get
hooked on either edge 155 or 158. The cigarette C really rests on
three points: the outer rim 155, the inner rim 158, and the stop
position of the wall 159 of the inner cup 152.
FIGS. 20 through 22 show what happens to a cigarette C in the ash
tray 150. If the cigarette C of FIG. 20 is simply left in place, it
progressively burns as shown in FIG. 21 and then as shown in FIG.
22. When the ash 162 eventually breaks after sliding of the
cigarette C, the stub 163 falls harmlessly into the well 164
between the inner and outer cups.
FIG. 23 shows what happens with a cigarette C that is smoked
intermittently. When it is placed in the ash tray 150, it assumes
the position shown here, and if it is left alone awhile after being
smoked, it slides further and it is ready to fall into the inner
cup 152.
FIG. 24 shows how the inner cup 152 can also be used to provide
accommodation for a short cigarette 165. The inner cup 152 may
have, as shown here, small notches or valleys 166 in the edge 158
to prevent roll of the cigarette 165, if this should be deemed
desirable.
FIGS. 25 and 26 show one further modification, an ash tray 170
which generally resembles the ash tray 150 but which is wider and
has a cone 171 inside the inner cup 172 to serve as a stop. Unlike
the use of the cone 40 in FIG. 1, the cone 171 here is used as a
stop and the ash E is placed up against it. In other words, a wide
ash tray 170 can have a wide central inner cup 172, so that the
cigarette C, if properly inclined as shown in FIGS. 25 and 26,
tends to come in to a bottom wall 173 rather than reaching the
opposite wall 174 of the inner cup 172. In order to make it wide
this way, it is desirable to have the cone 171 to serve as a
stop.
Another modification which is feasible is to have, as is shown in
FIG. 26, a small conical ring 175 somewhat analogous to the central
cone 40 of FIG. 1, placed in between the central cone 170 and the
wall 174 of the inner cup 172. The function of the conical ring 175
is to accommodate short cigarettes by keeping them up in the air
and helping to keep them burning.
To those skilled in the art to which this invention relates, many
changes in construction and widely differing embodiments and
