Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
A coaster for use with a container such as drinking glass
comprising a base having a stepped shelf formed therein to receive
a removable insert.
2. Description of the Prior Art
Moisture tends to form on the exterior surface of drinking glasses
and the like when used to serve iced drinks. This condensation, as
well as spillage, usually rolls off the glass and onto the
supporting surface. As a result, many tables and the like
supporting surfaces susceptible to condensation marks are
permanently damaged. Numerous attempts have been made to construct
various means of protecting such surfaces from condensation
damage.
The most common and widely known means of protecting these surfaces
from condensation from cold beverages is the use of coasters upon
which the drinking glass is placed. The coaster catches and retains
the liquid, thus preventing marring of the supporting surface.
Despite the numerous structures and configurations available, many
have various objectionable features.
A commonly used coaster comprises a cup-like structure which
permits a pool of liquid to accumulate therein. Since the glass
rests in this pool, drippings therefrom generally fall onto the
supporting surface and on the user's person.
Many coasters include a moisture absorbent material in direct
contact with the bottom of the drinking glass. Unfortunately, the
coaster tends to stick to the glass. Since the coaster often
dislodges after the glass is lifted, the user must either
physically separate the two or hold the two together while
drinking.
Another type of coaster comprises a one-piece tray formed with a
central recess therein to catch the liquid. A support stand may be
disposed within the recess to afford an elevated support for the
drinking glass. Many of these coasters are elaborate and costly to
mold and manufacture due to their structural features.
For the reasons discussed above, these and other devices have been
ineffective and not widely accepted. Thus, the need exists for an
effective, attractive and inexpensive coaster.
SUMMARY OF THE INVENTION
This invention relates to a coaster for use with a container such
as drinking glass. More specifically, the coaster comprises a base
configured to detachably retain a removable insert in cooperative
engagement therewith.
The base comprises an outer circular wall having a substantially
horizontal stepped shelf formed about the inner periphery thereof.
The stepped shelf includes an upper support surface having a
plurality of retaining nubs formed about its inner periphery and a
support ledge which cooperatively engages the removable insert as
more fully described hereinafter. The lower portion of the stepped
shelf comprises a cup shaped recess.
The removable insert includes an inclined outer periphery which
operatively engages the support ledge and retaining nubs when
operatively assembled. The insert further includes a plurality of
apertures formed therein to permit liquid and condensation to drain
therethrough and into the recess. In addition, the apertures
prevent a vacuum from forming between the insert and the recess to
facilitate removal of the insert from the base.
Since the insert is formed separately from the base, raised
printing may be imprinted on the upper surface thereof with
relative ease. Thus, the coaster may be personalized with initials
or used as a calling card or advertising device. In this manner, an
attractive, inexpensive, durable coaster capable of displaying
various information is provided.
The invention accordingly comprises the features of construction,
combination of elements, and arrangement of parts which will be
exemplified in the construction hereinafter set forth, and the
scope of the invention will be indicated in the claims.
BRIEF DESCRIPTION OF THE DRAWINGS
For a fuller understanding of the nature and objects of the
invention, reference should be had to the following detailed
description taken in connection with accompanying drawings in
which:
FIG. 1 is a top view of the present invention.
FIG. 2 is a side view of the present invention.
FIG. 3 is a cross-sectional side view of the present invention
taken along line 3--3 of FIG. 1.
FIG. 4 is an exploded cross-sectional side view of the present
invention.
Similar reference characters refer to similar parts throughout the
several views of the drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As best shown in FIGS. 1 and 4, the present invention comprises a
coaster generally indicated as 10 including a hollow, substantially
annular base 12 and a removable insert 14.
As best shown in FIGS. 3 and 4, the base 12 comprises a hollow
outer circular wall 16 having a substantially horizontal stepped
shelf 18 formed about the inner periphery thereof. The stepped
shelf comprises an upper support surface 20 having a plurality of
alternating grooves 22 and ridges 24, an annular Z-shaped inner
wall 25 and a recess bottom 28. These alternating grooves 22 and
ridges 24 prevent the glass (not shown) and coaster 10 from
sticking together when the support surface 20 is moist. Extending
inwardly about the inner periphery 30 of support surface 20 are a
plurality of retaining nubs 32. The retaining nubs 32 are
positioned relative to the supporting shelf 26 formed by the upper
portion of wall 25 to cooperatively form a retaining means. The
insert 14 is detachably secured to the base 12 by this retaining
means as more fully described hereinafter. The upper support
surface 20 and wall 16 cooperatively form retainer lip 34.
As best shown in FIGS. 1 and 4, the removable insert comprises a
flat substantially circular insert 14 including a plurality of
apertures 36 formed therein. The periphery of insert 14 is
dimensioned relative to the inner periphery 30 of support surface
20 and retaining nubs 32 such that inclined side wall 38 snap fits
therebetween to detachably secure the insert 14 to the base 12.
Thus assembled the insert 14, annular side wall 40 of inner wall 25
and recess bottom 28 cooperatively form reservoir 42. The apertures
36 permit liquid and condensation to drain therethrough and into
the reservoir 42. In addition, the apertures 36 prevent a vacuum
from forming between the insert 14 and recess bottom 28 to
facilitate separation of the insert 14 and the base 12.
As best shown in FIGS. 1 and 3, raised embossing generally
indicated as 44 may be formed on the upper surface 46 of the insert
14. Thus, the coaster 10 may be personalized with initials or used
as a calling card or advertising device. Since the insert 14 is
removable, a supply of bases 12 and blank inserts 14 may be made in
advance. The blank inserts 14 may then be embossed or otherwise
imprinted with the desired information. In this manner, an
attractive, inexpensive, durable coaster 10 is provided.
It will thus be seen that the objects set forth above, among those
made apparent from the preceeding description, are efficiently
attained, and since certain changes may be made in carrying out the
above methods and article without departing from the scope of the
invention, it is intended that all matter contained in the above
description shall be interpreted as illustrative and not in a
limiting sense.
It is also to be understood that the following claims are intended
to cover all of the generic and specific features of the invention
herein described, and all statements of the scope of the invention,
which, as a matter of language, might be said to fall
therebetween.
Now that the invention has been described,
