TECHNICAL FIELD OF THE INVENTION
[0001] This invention relates to vessels that are to be held in a hand to contain a substance
such as a liquid, a paste, a gel, a cream, a granulated substance, or any combinations
thereof.
BACKGROUND ART
[0002] The current art describes a large number of devices and vessels that typically employ
a handle, a sling or a strap to assist in holding a vessel of paint.
[0003] US Pat No. 4,927,046 and
US pat No. 6,138,963 describe containers that are to be gripped in the hand with a handle formed vertically.
However the action of gripping such a container has a potential to cause fatigue and
discomfort. In fact the grasping is made by the strength of fingers only. In other
words, the user is obliged to actively hold the vessel.
[0004] Taking a different approach, the device described in
US Pat No. 6,006,966 seeks to attach a can of paint to a belt worn by the painter such that hand fatigue
can be avoided. While this may be useful to avoid fatigue, other shortcomings relating
to the ease of movement and use while on a ladder or elsewhere.
[0005] An analogous approach is described in US Design Pat
No. D 499,553 which uses a body harness to suspend a paint container as a means of avoiding hand
fatigue.
[0006] The approach in
US Pat No. 6,708,838 and
US Pat No. 6,991,829 seeks to use an adjustable strap to urge the hand onto the vessel as a means to reduce
the active holding action of the hand that holds the vessel in order to reduce fatigue
and discomfort.
[0007] The current art therefore seeks either to provide a means of holding the vessel or
to suspend the vessel containing a liquid or other material. The existing devices
that are to be held in the hand either oblige the user to actively hold a device in
the hand or to use a strap to attach the vessel to the hand to reduce the effort required
to hold the vessel.
[0008] The present invention improves on the current art by overcoming the need to actively
hold a vessel. The present invention proposes to use the form of the hand as naturally
held when the forearm is extended and exploits that natural position to permit the
vessel to be held passively in the hand with the thumb in its natural position.
SUMMARY OF THE INVENTION
[0009] It is a an object of the invention to provide a hand-held vessel that is ergonomically
designed to contain a liquid, paste, gel or a granular material or other substance,
or more specifically paint or another liquid to be applied to a surface, and which
can be held with one hand while the other hand is free and can be used to hold an
instrument or an implement for applying the substance contained in the vessel.
[0010] According to the invention, there is provided a hand-held vessel comprising:
- a bottom wall ;
- upstanding walls projecting upwardly from the bottom wall and defining a cavity with
the bottom wall;

of the user. The upstanding walls comprise a concave surface adjacent to the curved
portion to fit the hand and the wrist of the user. The lip curves down such that it
provides an ergonomic shape against which the weight of the container may urge against
the index finger. The lip extends at an angle in relation to the upstanding walls.
The lip extends in a plane substantially parallel to the bottom wall.
[0012] The edges of the hole are coplanar with edges of the cavity.
[0013] According to one embodiment, the edges of the hole are open in a direction parallel
to the nearest edge portion of the cavity in such a manner that the hole forms a hook.
[0014] According to an alternative and preferred embodiment, the hole is oval.
[0015] According to one embodiment, the upstanding walls include a front wall portion angled
to protrude outwardly with a flat surface.

to hold a paint roller, a paint brush, a trowel, a spatula, a spoon, or other implement.
[0017] According to one embodiment, the lip can be provided with upwardly protruding pins
to attach implements such as a bracket provided with a clip 17 for holding a tool
such as a paint brush, paint roller, a trowel, a spatula, a spoon, or other implement.
[0018] According to another embodiment, the lip can be provided with holes to receive pins
of a bracket provided with a clip 17 for holding a tool such as a paint brush or paint
roller.
[0019] Advantageously, the shape of the vessel allows the stacking of one vessel inside
another vessel.
[0020] Advantageously, in another embodiment, the vessel can receive in the cavity a removable
lightweight insert made of thermoformed plastic.
[0021] According to another embodiment, a cover of flexible plastic can be positioned over
the open part of the device.
[0022] Various sizes of the vessel can be made ranging from one half a litre to more than
three litres. Preferably, the cavity has a volume of approximately one litre.
[0023] According to one embodiment, a second through hole is formed in the lip so that each
hole is located on each rounded corners of the lip where the back wall meets each
of the side walls.
[0024] According to one embodiment, two strap eyelets are formed on the lip and wherein
two other eyelets are formed on the junction between the bottom wall and the back
wall.
[0025] Preferably, the vessel has a geometrical plane of symmetry, so that it can be equally
used by right-handed and left-handed persons.
[0026] In this embodiment with two holes located on each rounded corner, the preferred volume
of the vessel is more than one litre.

DETAILED DESCRIPTION
[0028] Referring to figure 1, a vessel 1 according to a first embodiment of the invention
is made of moulded plastic having a useful volume that could vary of approximately
one half to more than three litres. The vessel comprises a bottom wall 2 that is connected
to a back wall 3. The back wall 3 has curved portions 4 where it is attached on each
or its two side edges to two side walls 5 and which are also attached to the bottom
wall 2. Each of the distal edges of the side walls are attached to a front wall 6
that is also attached to the bottom wall 2. The ensemble of the front wall 6 and the
two side walls 5 and the back wall 3 and the bottom wall 2 forms a container that
can be placed on a horizontal surface such that it is open at the top.
[0029] Further, the back wall 3 has a lip 7 that protrudes outwardly and at an angle from
the edge of the back wall such that the lip is in a plane parallel to the bottom wall
of the vessel, for approximately the posterior third of each of the side walls 5.
The back wall 3 and the lip 7 form a continuum. The lip 7 extends backwards from the
back wall 3 and is provided with an oval shaped hole 8 that is positioned in the centre
of the lip 7 where the major axis of the oval hole 8 is at a right angle to the back-to-front
axis of the vessel 1.
[0030] Advantageously, the lip 7 extends around corners where the back wall 3 joins each
of the side walls 5. The lip 7 demonstrates a slight curving down 13 such that it
provides a comfortable shape against which the weight of the vessel may urge against
the index finger.
[0031] The vessel 1 so formed permits a thumb to pass through the oval shaped hole 8 from
below the lip 7 of the back wall 3 and allows the palm and wrist to naturally rest
on the back wall which is provided with an ergonomic concave curvature 10 while the
fingers rest on a convex part of the outer surface of the back wall where the back
wall meets a side wall 5.
[0032] Advantageously, the form of the front wall 6 extends outwards at an acute angle from
the vertical plane such that it provides a flat surface which may have indentations
of different forms against which different implements such as a paint brush, a paint
roller, a trowel, a spatula, a spoon, or other implement can be urged to enhance the
loading of the liquid, paste, gel, or granulate or other substance contained in the
vessel onto such an implement.
[0033] As shown in figure 1, the front wall 6 is provided with a notch 14 to hold a paint
roller. The upper corner edges of the vessel are provided with one or two or more
sets of pins 15 for securing a bracket 16 provided with a clip 17 for holding a tool
such as a paint brush, paint roller a trowel, a spatula, a spoon, or other implement
or accessory.
[0034] In a further embodiment (not shown), the upper surface of the corner edges of the
lip provide for one, two or more sets of holes into which pins can be inserted such
that a clip 17 for holding implements or tools such as paint brush, paint roller a
trowel, a spatula, a spoon, or other implement or accessory.
[0035] Referring to figures 2 and 3, a vessel according to a second embodiment of the invention
is made of moulded plastic having a useful volume of approximately three litres that
is comprised of a bottom wall 2 connected to a back wall 3. The back wall 3 has curved
portions where it is attached on each or its two side edges to two side walls 5 which
are also attached to the bottom wall 2. Each of the distal edges of the side walls
5 are attached to the front wall 6 that is also attached to the bottom wall 2. The
front wall 6, the two side walls 5, the back wall 3 and the bottom wall form a container
that can be placed on a horizontal surface such that it is open at the top. The back
wall has a lip 7 including a portion that protrudes outwardly and perpendicularly
from the back wall 3 and portions that extend outwardly from each of the side walls
5 for approximately the posterior third of each of the side walls 5.
[0036] In this embodiment, the lip 7 has two oval shaped holes 8 that are positioned in
an area where the curvature of the junction of the back wall 3 with the side wall
5 takes place. The major axis of each oval hole 8 follows the curvature of the junction
between the back wall 3 and the corresponding side wall 5. Two strap eyelets 11A,
11B are formed on the lip 7 and positioned on each side of the through holes 8. Two
other eyelets 12A, 12B are formed on the junction between the bottom wall 2 and the
back wall 3, so that a strap can be attached to the vessel.
[0037] Advantageously, the lip is positioned around that curvature and demonstrates a slight
downward curving 13 that provides a comfortable form against which the index finger
may be urged. That curving down 13 is also comfortable for the forearm against which
the lip 7 will be urged to take the weight of the vessel 1.
[0038] In both embodiments, the vessel has a geometrical plane of symmetry, which means
that it can be equally used by right-handed and left-handed persons. The walls of
the vessel are so shaped that one vessel can be stacked inside another vessel. An
insert can be sat exactly inside the vessel 1 and can be placed inside the vessel
1 and removed with the liquid or other material contained in that insert. A cover
comprised of a plastic film with elastic can be sewed or otherwise located on the
circumference that can permit the cover to be stretched over the open portion of the
insert or the vessel.
