BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to straws and, more particularly, to a straw effective
in transferring solids in a beverage from its container to a user's mouth and preventing
the solids in the beverage from clogging the straw.
2. Description of the Prior Art
[0002] FIG. 1 shows a conventional straw. The conventional straw is a plastic tube 20 provided
centrally with a channel 21. The conventional straw is for transferring a beverage
from its container to a user's mouth and taking in bone marrow of cooked long bones
of animals. In general, the conventional straw has a diameter of 0.5cm approximately,
but has a larger diameter, i.e., 1.5cm, for use in taking in yogurt, bubble tea, etc.
[0003] The straw is capable of transferring a beverage and food from its container to a
user's mouth by the principle that "the gas pressure inside the straw is lower than
the atmospheric pressure outside the straw". The user sucking the straw removes some
air therefrom and thus reduces the pressure inside the straw; hence, the atmospheric
pressure outside the straw is higher than the gas pressure inside the straw. The pressure
difference causes the liquid inside the straw to rise. Gaseous communication between
the inside of the straw and the outside occurs as soon as the user's mouth separates
from the straw, and in consequence the gas pressure inside the straw equals the atmospheric
pressure; hence, the pressure difference is reduced to zero, thereby causing the liquid
inside the straw to descend. Likewise, a crack in the wall of the straw will enable
gaseous communication between the inside of the straw and the outside, even if the
user sucks the straw with the other end thereof placed in a beverage, and in consequence
the gas pressure inside the straw equals the atmospheric pressure; hence, the straw
with the crack is not capable of transferring the beverage from its container to the
user's mouth.
[0004] In the 19
th century, Americans were fascinated by icy, mildly-flavored alcohol, and they prevented
heat in their mouths from lessening the iciness of the alcohol with a hollow-cored
wheat straw inserted into the alcohol in a container rather than drinking the alcohol
directly from the container. However, wheat straws not only break easily, but their
flavor also permeates the alcohol. Dissatisfied with wheat straws and inspired by
paper cigarette holders, Marvin Chester Stone, an American manufacturer of paper cigarette
holders, invented a paper straw which does not break down and leave a gritty residue
in the beverage. From then on, paper straws are used in drinking mildly-flavored alcohol
and icy beverage alike.
[0005] The birth of modem plastics was followed by the replacement of paper straws with
plastic straws which human beings are using nowadays, as plastic straws are easier
to manufacture, more flexible and attractive than paper straws.
[0006] There is an increasingly strong, ongoing demand for beverage. Furthermore, beverage
nowadays often contains tapioca pearls, konjac, chopped fruit, etc. The conventional
straw is designed to have its bottom end rested on the bottom of the container; as
a result, not only are the tapioca pearls, konjac, and chopped fruit in beverage denied
entry into the straw, but they also cluster around the bottom end of the straw and
thus ultimately clog the straw.
[0007] Fruit tea, inclusive of chopped fruit, is often introduced into beverage nowadays.
However, it is only after consumers have drunk the beverage that the consumers take
the chopped fruit out of the empty container and eat the chopped fruit, because it
is difficult to take the chopped fruit out of the beverage with the conventional straw.
As a result, the conventional straw is useless for the chopped fruit.
SUMMARY OF THE INVENTION
[0008] The objective of the present invention is to provide a straw effective in transferring
bulky solids, such as chopped fruit, in a beverage from its container to a user's
mouth and preventing solids in the beverage from clogging the straw.
[0009] The straw of the present invention comprises a straw body. The straw body is hollow-cored,
cylindrical and made of a plastic material. The straw body has one end provided with
a plurality of branch portions and a plurality of openings disposed between the branch
portions, wherein the branch portions each have a body segment and a top segment.
The body segment has one end connected to the straw body and the other end connected
to the top segment. The body segment is entirely of substantially equal width. The
top segment has an arcuate outer end.
[0010] In a preferred embodiment, a plurality of tooth portions is disposed on the edge
of each said branch portion.
[0011] In a preferred embodiment, the openings are in the number of two and oppose each
other radially across the straw body, whereas the branch portions are in number of
two and oppose each other radially across the straw body.
[0012] In a preferred embodiment, the branch portions are in the number of four, with two
paired said branch portions opposing two other paired said branch portions radially
across the straw body, whereas the openings includes two first openings and two second
openings, with the two first openings opposing each other radially across the straw
body and being between two non-paired said branch portions, and the two second openings
opposing each other radially across the straw body and being between two paired said
branch portions.
[0013] In a preferred embodiment, the two first openings are larger than the two second
openings.
[0014] In a preferred embodiment, the openings each have an arcuate bottom end.
[0015] In a preferred embodiment, the openings each have a maximum depth equal to one to
two times the inner diameter of the straw body.
[0016] With the aforesaid structure and components, the straw of the present invention is
effective in transferring bulky solids, such as chopped fruit, in a beverage from
its container to a user's mouth and preventing solids in the beverage from clogging
the straw.

DETAILED DESCRIPTION OF THE EMBODIMENT OF THE INVENTION
[0018] Referring to FIG. 2 and FIG. 3, the present invention provides a straw comprising
a straw body 10. The straw body 10 is hollow-cored, cylindrical and made of a plastic
material. One end of the straw body 10 has two branch portions 11 and two openings
12 disposed between the two branch portions 11. The two openings 12 oppose each other
radially across the straw body 10. Likewise, the two branch portions 11 oppose each
other radially across the straw body 10. The branch portions 11 each have a body segment
111 and a top segment 112. The body segment 111 has one end connected to the straw
body 10 and the other end connected to the top segment 112. The body segment 111 is
entirely of substantially equal width. The top segment 112 has an arcuate outer end.
The openings 12 each have a maximum depth equal to one to two times the inner diameter
of the straw body 10. The openings 12 each have an arcuate bottom end.
[0019] Referring to FIG. 4, to use the straw of the present invention, a user places the
straw body 10 directly in a container which holds a beverage. The beverage contains
edible solids, including tapioca pearls, chopped fruit, konjac, etc. The beverage
may be replaced with a mixture of beverages. Afterward, the user eats the chopped
fruit and konjac in the beverage with the branch portions 11. To take in the tapioca
pearls, the user sucks the straw body 10 so that the tapioca pearls enter the straw
body 10 through the openings 12. Referring to FIG. 5, if the beverage is running out,
the user may press down the straw body 10 to bend the branch portions 11 so as for
the straw body 10 to get closer to the bottom of the container, thereby allowing the
user to use up the beverage.
[0020] Referring to FIG. 6, the straw body 10 in the second preferred embodiment of the
present invention is distinguished from the straw body 10 in the first preferred embodiment
of the present invention as follows: in the second preferred embodiment, the branch
portions 11 are in the number of four; two paired said branch portions 11 oppose two
other paired said branch portions 11 radially across the straw body 10; the openings
12 includes two first openings 121 and two second openings 122; the two first openings
121 oppose each other radially across the straw body 10 and are between two non-paired
said branch portions 11; and the two second openings 122 oppose each other radially
across the straw body 10 and are between two paired said branch portions 11.
[0021] Referring to FIG. 7, in the third preferred embodiment of the present invention,
the straw comprises the straw body 10. One end of the straw body 10 has four branch
portions 11 and four openings 12 each disposed between two corresponding ones of the
branch portions 11. The branch portions 11 are equal in shape and size. The openings
12 are equal in shape and size. Referring to FIG. 8, the straw body 10 in the fourth
preferred embodiment of the present invention is distinguished from the straw body
10 in the third preferred embodiment of the present invention as follows: in the fourth
preferred embodiment, a plurality of tooth portions 113 is disposed on the edge of
each branch portion 11 to increase the friction between the branch portion 11 and
food being transferred by the straw.
[0022] Therefore, the straw of the present invention is effective in transferring solids
in a beverage from its container to a user's mouth and preventing the solids in the
beverage from clogging the straw.
