Description
FIELD OF THE INVENTION
[0001] The present invention relates to a cup cover structure
device, and particularly to such device where a cup body may be
further reinforced by using a cup rim having a flat shape, a cup
cover may also be provided with a stable closure with the flat cup
rim by enabling a screw magzine to stop against an extension
portion of the flat cup rim so that the screw magzine may reach a
closure fixation with the flat cup rim and the extension portion
through a rotational or swagging fashion, so as to fix the cup
cover and the cup body as a single body to maintain the single body
to firmly stand as possible as it can and increase a structural
strength of the paper cup, whereby the paper cup is provided with a
flater, solid, safe and enduring structure, and achieves a less
leakage and an efficacy of an easier fixation of the paper cup.
DESCRIPTION OF THE RELATED ART
[0002] A conventional paper cup, as shown in FIG. 7, has a
protruding rim 31 disposed circumferentially at an upper end
thereof, which is embeded into an indented groove 41 of a cup cover
4. Presently, all paper cups have their protruding rim 31
presenting a circular side and rolled axis shape, and which has a
weak structural strength. When the cup cover 4 and the cup body 3
are embeded together, the protruding rim 31 of the cup body 3 is
apt to have a deformity, i.e. become flattened and small.
[0003] At this time, between the indented gap 41 of the cup cover 4
and the protruding rim 31 of the cup body 3 has a larger gap,
resulting in that the porotruding rim 31 may not firmly be embeded
into the indented groove 31. Hence, the cup cover 4 is apt to get
loosened, or may not tightly or may only slightly cover the cup
body 3, forming a non-closed state. Out of the closed tate, the
liquid within the cup may overflow, resulting in a convenient use
of the cup and a unsanitary state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Referring to FIG. 1 and FIG. 2, an exploded schematic
diagram according to a first embodiment the present invention, and
a schematic diagram of a use state according to the first
embodiment of the present invention are shown therein,
respectively. As shown, the paper cup cover structure device
comprises a cup 1 and a cup cover 2. The cup 1 is made of paper,
and comprises a cup body 11, a cup opening 12 disposed at a top of
the cup body 11, a cup bottom 13 disposed at a bottom of the cup
body 13. The cup opening 12 has an outer rim disposed at an outer
circumference thereof, and on the outer rim a flat cup rim 14 may
be disposed circumferentially by using frame molding or paper
molding.
[0021] The cup rim 14 is made of plastic or paper which may be
bio-dissolved and has a flat face 141 and an extension portion 142
cirucum-ferentially disposed downwards with respect to the outer
rim. The outer rim 14 and the extension portion 142 are formed as a
double-layered structure by folding up a pressed fit curling (not
shown) formed circumferentially at the cup opening 12.
[0022] The cup cover 2 is placed at an inner wall face 21
corresponding to the cup rim 14, and has a screw magzine 22
circumferentially disposed with respect thereto. The screw magzine
22 has a push-stop portion 23 extending from a bottom thereof. The
push-stop portion 23 takes a shape of an inverse hook and runs
slightly outwards, and has a protruding rib 231 disposed
circumferentially at an inner side thereof, so that the cup rim 14
and the screw magzine 22 form a rotational closure with each other.
Further, the protruding rib 231 stops against a lower rim of the
cup rim 14, and thus the cup cover 2 is combined on the cup cover
2. As such, the novel paper cup cover structure device is
formed.
[0023] In fabrication, the cup rim 14 is formed with plastic or
paper by using frame molding or paper molding. In operation, the
cup cover 2 may be combined on the cup body 1 as a closure. The cup
body 1 may be further reinforced by using a cup rim 14 having a
flat shape, the cup cover 2 may also be provided with a stable
closure with the flat cup rim 14 by enabling the screw magzine 22
to stop against the extension portion 142 of the cup rim 14, so
that the screw magzine 22 may reach a closure fixation with the
flat cup rim 14 and the extension portion 142 through a rotational
or swagging fashion when the cup body 1 and the cup cover 2 are
combined together. In this manner, the cup cover and the cup body
are fixed as a single body to maintain the single body to firmly
stand as possible as it can and increase a structural strength of
the paper cup, whereby the paper cup is provided with a flater,
solid, safe and enduring structure, and achieves a less leakage and
an efficacy of an easier fixation of the paper cup.

schematic diagram of a use state according to the third embodiment
of the present invention are shown therein, respectively.
[0025] As shown, the present invention may not only provide the
structure presentation as what the first embodiment shows, but also
the structure presentations as what the second and third
embodiments. The difference dwells in that the push-stop portion
23a is inclined and runs outwards. The push-stop portion 23a has a
protruding rib 231a (shown in FIG. 3 and FIG. 4) circumferentially
disposed at an inner side thereof, or a plurality of ribs spacedly
and circumferentially arranged at the inner side, so as to stop
against a lower rim of the cup rim (shown in FIG. 5 and FIG.
6).
[0026] In this manner, the paper cup may not only achieve in the
efficacy what the first embodiment possesses, but also meet the
requirement in different use states by the cup body 1 and the cup
cover 2.
[0027] In summary, the paper cup cover structure device of the
present invention has the essential features that the cup body may
be further reinforced by using a cup rim having a flat shape, the
cup cover may also be provided with a stable closure with the flat
cup rim by enabling a screw magzine to stop against an extension
portion of the flat cup rim so that the screw magzine may reach a
closure fixation with the flat cup rim and the extension portion
through a rotational or swagging fashion, so as to fix the cup
cover and the cup body as a single body to maintain the single body
to firmly stand as possible as it can and increase a structural
strength of the paper cup, whereby the paper cup is provided with a
flater, solid, safe and enduring structure, and achieves a less
leakage and an efficacy of an easier fixation of the paper cup.
