Description
TECHNICAL FIELD
[0001] The present invention relates to coffee mugs in general.
More specifically to a mug with interchangeable accessories for
personalizing its appearance and tactile qualities.
BACKGROUND ART
[0002] Previously, many styles and types of coffee mugs have been
developed in endeavoring to achieve a pleasing appearance and
handling qualities. Prior art has attempted to accomplish this
quality by making a large number of individual mugs each having
different characteristics however none have made these features
interchangeable.
[0003] A search of the prior art did not disclose any patents that
possess any of the novelty of the instant invention, however the
following U.S. patents are considered related:

[0004] Letsch et al. in U.S. Pat. No. 4,754,888 discloses a carafe
with an inner container surrounded by a casing. The inner container
and the casing have an opening at the top which may be closed by a
separate plug. The plug and opening in the container and casing are
shaped such that it is possible to fill or empty the inner
container while the plug is still in the opening. The plug and
container both have mating grooves that provide opposed flow paths
into and out of the container. The container also includes a basin
around the top for receiving coffee from a coffee maker and the
plug has openings to provide a flow path from the basin into the
container interior.
[0005] Karp in U.S. Pat. No. 5,249,703 teaches a travel mug that
includes a container and a lid in combination. The container has a
handle and an annular lip that has an annulus capable of forming a
seal with the top side of the annular lip. A cylindrical well in
the lid has a vertical dividing wall such that the lid may be
readily rotated by hand. The retaining arms extend from the
underside of the lid and engage the underside of the annular lip to
pull it into tight abutment. Diametrically opposed gaps in the lip
act as passageway for the retaining arms. Similarly diametrically
opposed notches in the lid align with the gaps to allow liquid to
be poured from the container.
[0006] U.S. Pat. No. 5,918,761 issued to Wissinger is for an
insulated container and cover combination that has an outer
container shell terminating at an opening with a surrounding edge.
An inner container shell is nested within the outer container shell
and has an opening surrounded by a continuous edges in abutment
with the surrounding edge. The inner container shell is spaced
inwardly and is out of contact with the outer shell. A cover
mounting assembly is attached to the outer shell adjacent to the
opening. A single seal, made of elastomeric material, has a sealing
surface disposed at the interface of the shells. Locating rings
define the removable cover-mounting assembly and locate the single
sealing ring on the inner and outer shells.
[0007] For background purposes and as indicative of the art to
which the invention is related reference may be made to the
remaining cited design patents.
DISCLOSURE OF THE INVENTION
[0008] Coffee mugs are frequently used by many people and they are
carried from place to place throughout the entire day becoming a
rather personal item. Fairly recently stainless steel vacuum
insulated or double wall coffee mugs have been introduced that have
a very attractive appearance and they are popular in this country
as well as throughout the world. Since these mugs have an advantage
in there insulating qualities and are shaped pleasing to the eye,
they can become a source of pride to the user. In an attempt to
fill the needs of the public, many different shapes and styles of
mugs have been developed and marketed. The problem of taste still
remains, however, since what is attractive to one person may not
look good to another.
[0009] Therefore a primary object of the invention is to have a mug
with interchangeable accessories permitting the indivedual to
select the combination of components that appears to be the best in
their personal judgment. By marketing the accessory components
separately individuals may not only select the combination that is
pleasing in appearance to their taste but may choose a handle that
has a good feel and is easy for the person to grip, therefore both
the attractiveness and comfort may be simultaneously satisfied.
[0010] Another object of the invention is that the lid, handle and
docking station may all be selected individually. The lid may have
different color, surface finish and features such as a simple
opening for pouring, a stopper for positive leak tight sealing or a
convenient sliding cover. The handle includes a replaceable bracket
that fits into a groove in the mug body which may have a number of
shapes and colors with the handle itself varying in shape and size.
The handle is attached to the bracket with a clip that blends into
the shape of the handle and yet is removable per se. To assure a
constant tight fit between the bracket and the mug body optionally
a bracket may be selected, containing a number of radial grooves
that are spaced around its periphery. The radial grooves retain
small o-rings that compress and hold the bracket securely in place
in applications where its use requires structural integrity.
[0011] An important object of the invention is directed to the
ability of the mug to have a docking station attached to the
bottom. The removable docking station has threads in the center to
mate with mating threads in the coffee mug base. This permits the
best of both worlds in that when the coffee mug is used on a flat
surface the station permits it to be very stable since the base is
large enough to spread the weight evenly over a liberal area and
yet when the docking station is removed it fits easily into vehicle
cup holders. The stability is extremely important as it is common
to place a coffee mug in close proximity to keyboards, papers and
work surfaces where coffee spills could be catastrophic. Further
the configuration of mug is specifically sized to fit almost all
conventional cup holders in a wide number of motor vehicles.
[0012] Still another object of the invention is that a retailer may
stock a wide variety of accessories and replace only the well
accepted components as required, not leaving the unpopular items
overstocked as is the case with the complete individual mugs.
Furthermore replacement of components may be easily made at a later
date, if the user decides to update the mug or if breakage
occurs.
[0013] These and other objects and advantages of the present
invention will become apparent from the subsequent detailed
description of the preferred embodiment and the appended claims
taken in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION
[0067] The best mode for carrying out the invention is presented in
terms of a preferred embodiment. This preferred embodiment is shown
in FIGS. 1 thorough 53 and is comprised of a basic coffee mug 60
having a body 62 which has an open top 64, a bottom 66 and sides 68
with a circumferential groove 70 around an upper outside surface of
the sides 68. A base 72 is attached to the bottom 66 and includes
integral female threads 74 on its underside as illustrated in FIG.
2. The sides 68 are preferably constructed using stainless steel
dual walls, having either a dead air space or negative pressure
therebetween for thermal barrier insulation, and the bottom 66 is
insulated by the base 72 which is thermoplastic in its
construction.
[0068] The accessories for the coffee mug body 62 include a
removable lid 76 disposed onto the mug body open top 64 as
illustrated in FIG. 1. The lid 76 may be in a number of different
configurations as optionally shown in FIGS. 3 to 5 in which FIG. 3
illustrates a partial isometric view of the removable lid 76 in the
sliding cover configuration 78 for protecting liquids contained
within the mug. FIG. 4 depicts the removable lid in the stopper
configuration 80 and FIG. 5 shows the lid in the basic opening
configuration 82. While only three configurations are illustrated
it is not to be construed as limiting as a myriad of other styles
and shapes may also be used for the lid 76.
[0069] The next optional accessory is a replaceable handle bracket
84 configured to interface with the groove 70 in the mug body sides
68, as shown attached in FIG. 1. Again three basic configurations
are presented with FIGS. 6 and 7 illustrating a round ring
structure 86 to mate in a inversely proportional manner with the
groove 70 in the mug sides. FIGS. 8 and 10 depict an oval ring
structure 88 having a bead on inside surface with FIGS. 9 and 11
showing a rectangular structure 90 with radiused edges and a bead
on both the inside and the outside surface, again the similar bead
on the inside surface mates with the groove 70 in the mug sides. A
variation of the round ring structure 86 is shown in FIGS. 12 to 19
which has radial grooves 92 spaced at a predetermined distance
apart around the bracket circumference with an o-ring 94 disposed
within each groove 92 for maintaining a close and tight fit between
the bracket 84 and the mug body 62. In any event the handle bracket
84 includes a pair of parallel protruding ends 96 with each end
having a notch 98 therein for interfacing with a handle. The notch
98 may be on the inside surface as shown in FIGS. 12 to 15 or the
outside surface as illustrated in FIGS. 16 to 18. While the
preferred embodiment of the ends 96 are round as depicted in FIGS.
6 through 15 and 19 they may also be square as shown in FIGS. 16 to
18 either functioning in a similar manner.
[0070] A detachable handle 100, with a retaining clip 102, is
connected onto the handle bracket 84 and held in place securely
with the clip 102. There are two holes 104 within the upper portion
of the handle 100 for receiving the parallel protruding ends 96 of
the handle bracket 84 either round or square according the shape of
the ends 96. When assembling the handle 100 to the bracket 84 the
ends 96 are compressed together and the handle is slipped over
these extending ends such that the bracket 84 is held tightly
against the mug body 62 and retained within the groove 70. There
are an infinite number of configurations of handle shapes that
could be used however only a few are indicated in the drawings. As
an example FIG. 21 is a partial isometric view of the detachable
handle 100 with a tapered end. FIG. 22 illustrates the detachable
handle 100 with a rounded end and FIG. 23 a tapered shank. FIG. 24
shows a curved contour while FIG. 25 has a recessed upper section.
Finally FIG. 26 depicts the detachable handle 100 with a gradual
curved outline further this embodiment illustrates square holes 104
to mate with the optional square parallel protruding ends 96 shown
in FIGS. 16 to 18.
[0071] The handle 100 includes at least one cavity 106 for
receiving and positioning the retaining clip 102 which is in three
separate embodiments illustrated in FIGS. 27 through 44. The
preferred embodiment is shown in FIGS. 27 through 32 and
illustrates a retaining clip 102 that has a pair of integral
snap-in barbs 108 configured to interface with the cavity 106
within the detachable handle 100. It may be visualized that the
clip 102 is slightly smaller than the cavity 104 and that the
cavity has mating indentations that receive the snap-in barbs 108
holding the clip 102 in place and a downward projecting inverted
post 110 that interfaces with the notches 98 on the ends 96 of the
handle bracket 84. FIGS. 33 through 38 and illustrates the second
embodiment a retaining clip 102 that also has a pair of integral
snap-in barbs 108 however it is configured to encompass the entire
top and sides of the handle cavity 106. This so called encompassing
clip 112 includes an inverted post 110 that is positioned between
the protruding ends 96 and the clip 112 has a pair of v-shaped
projections 114 that slip into the notches 98 on the ends 96 of the
handle bracket 84 as the notches are located on the outside surface
of the ends 96 and are in an inverted v-shape. FIGS. 39 through 44
and illustrates the third embodiment of the clip 102 which also
encompasses the handle 100 except the notches 98 are wide enough to
receive the ends of the clip 102 and a inverted post 110 penetrates
the handle as above. It should be noted that only one embodiment
will be used in marketing the interchangeable accessories according
to the invention.
[0072] The final element of the interchangeable accessories is a
removable docking station 116 that is rotatably fastened to the
base 72 of the coffee mug 60 as illustrated in FIG. 1. The docking
station consists of a main docking station member 118 including, a
top and a bottom, with the bottom larger in surface area than the
coffee mug base 72. A recess 120 is formed in the top and includes
an elevated peripheral lip sized to fit over and enclose the coffee
mug base 72. A raised pedestal 122 is formed within the recess 120
of the docking station member 118, and a number of partial male
threads 124 depend outwardly from the body raised pedestal 122,
such that when the docking station member 118 is mated with the
coffee mug base 72 and rotated, the male threads 124 interface with
the base's female threads 74 bringing the pedestal 122 into
intimate contact with the base 72, thus fastening the docking
station 116 to the base 72 of the coffee mug 60 in a removable
manner. The docking station 116 may have an optional ornamental
design configuration as shown in FIGS. 45 through 53 in various
colors and textures. FIG. 45 illustrates in a partial isometric
view an unadorned shape of the removable docking station 116. FIG.
46 shows a scalloped shape of the ornamental design with FIG. 47
illustrating a radial cut-out shape, further FIG. 48 has a lip
shape and FIG. 49 a dimpled shape. FIG. 50 depicts an arched shape
ornamental design and is cut away to illustrate a resilient pad 128
that may optionally be attached to the bottom of any of the
stations 116 for increasing the stability of the coffee mug 60 on a
flat surface, such as a table or counter top and also to create a
non-slip substructure. FIG. 51 depicts a wavy shape, with FIG. 52
an indented shape and finally FIG. 53 is a partial isometric view
of a rippled shape of the removable docking station 116 in the
ornamental design configuration.
[0073] The lid 76, handle bracket 84, detachable handle 100,
retaining clip 102 and docking station 116 are all formed of a
thermoplastic material preferably selected from a group consisting
of polycarbonate, polyethylene, polyimide, polystyrene,
polypropylene, polysulfone, polyurethane, and
ethylene-vinyl-acetate and has an outside finish that is textured
in one manner or the other.
[0074] It should be noted that main novelty of the invention is to
individually select a combination of these accessories to
personalize the appearance and tactile qualities of the coffee
mug.
[0075] While the invention has been described in complete detail
and pictorially shown in the accompanying drawings, it is not to be
limited to such details, since many changes and modifications may
be made to the invention without departing from the spirit and
scope thereof. Hence, it is described to cover any and all
modifications and forms which may come within the language and
scope of the appended claims.
