Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This is a continuation of my provisional application No.
61/296,736 which was filed on 20 Jan. 2010, titled "Dome lids and
cups for hot beverages."
FIELD OF THE INVENTION
[0002] This invention relates to a lid and cup as one unit to
regulate hot drinks. The lid helps reduce temperature to enjoy hot
drinks and decreases burn incidents. More particularly, the present
invention directs the dome lid clipped on the mouth of the cup
described herein as a unit for hot beverage handling. The top
surface (planar) of the dome lid provides two drink openings on the
top rim portion, one with an ordinary opening and the other with a
narrow opening equipped with "cooling chambers" before the hot
drink reaches the mouth. The dome lids have an added future
recessed cup holder to securely hold a second cup placed on top of
the dome lid which will prevent falls and spills. In addition, the
cup is equipped with bellowed wall regions allow air to cool off
the fingertips from heat emanating from the cup walls while
resisting cups to slip off from the fingers. Further more, the cup
bottom is designed to fit on top of these recessed dome lids to
allow stacking.
BACKGROUND OF THE INVENTION
[0003] Disposable paper cups with lids for hot drinks are commonly
used. However, carrying a cup with hot liquids with bare hands is
dangerous and the hot liquids can burn a person internally if
liquids are consumed right away. Therefore, there is a need for
skills in this practice with advanced lid and cup designs to
channel hot drinks for safety by reducing the probability of
burning fingers, lips and tongues.
DESCRIPTION OF THE PRIOR ART
[0004] There is one United States patent which provides certain
basic knowledge of some features of the dome cup lids of the
present invention, but said cup lids are not otherwise suitable for
purposes of the present invention. This patent is, however,
referred to for purposes of establishing basic knowledge as to the
prior art.
Van Melle U.S. Pat. No. 4,460,103 provides dome lids without a
cooling chamber or bellowed cup walls, so it is disadvantageous to
handle hot beverages with the current invention.
SUMMARY OF THE INVENTION
[0005] The cup section of the current invention provides the cup
wall with horizontal bellowed stripes regions away from the edge of
wallpaper lapped member in symmetry on the lower region of the cup.
The valley sections of horizontal bellow regions limits fingertip
touching surface to the cup wall to reduce heat transfer and to
prevent the cup to slip off from the fingertips. Therefore, this
bellowed cup skill can eliminate commonly used cup rings to protect
fingers from hot cup walls. If a cup wall forms bellows all around,
then a cup wall becomes structurally weak from the pressure above.
In addition, the cup bottom is formed in accord with the cup
holding recess on top planar of dome lid to securely fit the second
cup bottom should you choose to stack them. The bellows section
formed on the cup wall is uneven.
In addition, the dome lid section of the current invention is
equipped with two drink openings in opposite sides of each other on
the planed top rim portion, one with a narrow opening hole and the
other with a regular opening. An internal plastic sheet equipped
with small puncture holes "cooling filter." shields on the narrow
opening hole to create "cooling chamber" along with the multiple
small external air intake holes. Both cooling filter and external
air intake holes create a "cooling chamber" to mix hot liquid came
through the cooling filer with external cold air. Hot drinks must
flow through each small puncture holes expose liquid more surface
to the external air in the cooling chamber to evaporate to cool off
temperature known as "the effect of vaporization." In addition, the
skill to mix hot beverages in the cooling chamber with air, allows
the inherent liquids natural aroma to disperse into the air and be
detected at nose sensory area as liquids are dispersed in the mouth
directly from the drink opening. The other advantage of the dome
lids equipped with cup holding recess is to hold the bottom section
of the 2.sup.nd cup securely which prevents a stacked 2.sup.nd cup
on skilled lid from falling off and spilling. Furthermore, the two
drink openings of the dome lids located well above the hot drink
surface help to prevent the hot beverage leaks through the
openings. These and other features and advantages of domed cup lids
combined with horizontal bellowed cup wall regions are described in
greater details hereafter.

cup 40, in keeping with this invention, are referred to hereafter
using the same reference numerals, for ease of understanding.
Typically, the disposable dome lid 10 is made out of a thin sheet
of polystyrene. Therefore the cooling filter 37 portion of the
present invention may be stamped internally on near narrow drink
opening 12 section separately as an integral part of the dome lid
and external air take small holes 33 on the inner circular wall 32
on both side of the opening 12 in symmetry to form the cooling
chamber 35. The space in between external air take holes 33 in
symmetry is created since the space is covered with upper lip when
liquids are consumed. The present invention of disposable dome lid
FIG. 1 is generally circular in configuration, and has a circular
planar top rim surface 18 formed by the inner circular wall 32 and
outer circular wall 24 equipped with the narrow drink opening 12
and the regular drink opening 22 in opposite sides. The outer
circular side wall 24 depends generally downwardly from the top rim
surface 18, and form circular cup rim gripper 26 and an outer
circular apron 28. Inner circular side wall 32 extends downwardly
from the top rim surface 18 to slightly above the cup rim gripping
section 26 to form a circular planar top surface 36. FIG. 2 shows
cooling filter 37 and external air take holes forming cooling
chamber 35 in relationship to the other part of lid 10. FIG. 3
shows narrow drink opening 12 equipped with smaller puncture hole
on the cooling filter 37 in order to expose large fluid surface
into the external air taken from the external air take holes 33 to
cool off before reaching to a mouth. On the other hand, regular
drink opening 22 is equipped with larger puncture hole on the top
rim surface 18 in order to enjoy a large portion of hot drinks when
the temperature come down. Also it shows a circular planar top
surface 36, cup bottom locking stubs 16 and the inner circular side
wall 32 forms cup holding recess 31 to secure a stacked up 2.sup.nd
cup on top of the first dome lid. In addition, it shows the outer
circular sidewall 24 depends generally downwardly from the top rim
surface 18, and form circular cup rim gripper 26 and an outer
circular apron 28. FIG. 4 shows a typical bellowed cup 40 of the
present invention and the positions of bellows 44 and flat cup wall
sections 46 in relationship to the edge of the cup wall lapped
member 42. FIG. 5 shows an elevated cross-section in the direction
of arrow 7-7 in FIG. 4 positioning the cup wall lapped member 42 in
the middle of the bellows 44. FIG. 6 shows the dome lid FIG. 3
