BACKGROUND ART
[0002] Generally, a straw has a passage formed therein to pass a
beverage therethrough, and if the front end of the straw pulls by a
user's lips in the state where the rear end of the straw is
inserted into the beverage stored in a container, the beverage is
sucked in the user's mouth through the passage of the straw.
[0003] If the user's lips are free from the straw during the
beverage is sucked through the straw, however, the beverage sucking
in his or her mouth moves back to the container, together with his
or her saliva, thus deforming the beverage or making the beverage
unsanitary.
[0004] If the beverage in one container is sucked through a
plurality of straws used by different users, their saliva are mixed
in the container. For example, if one beverage container is used
together with the person who is infected with pathogens, the
beverage accommodated in the container becomes infected with the
pathogens, thus making the beverage unsanitary to cause even
persons who are healthy to be infected seconarily with the
pathogens.

to the outside.
[0046] At this time, the discharging outlet 340 of the case 300 is
open and closed by means of a cap selected from well known caps,
and therefore, an explanation on the opening and closing of the
discharging outlet 340 will be avoided for the brevity of the
description.
[0047] Further, the case 300 has circumferential grooves 360 spaced
apart from each other along the outer peripheral surface thereof in

contaminant discharging portion 40 therein. Furthermore, the case
300 has the discharging outlet 340 formed at the underside thereof
to discharge the beverage containing the contaminants accommodated
in the storage space 320 to the outside.
[0051] At this time, the discharging outlet 340 of the case 300 is
open and closed by means of a cap selected from well known caps,
and therefore, an explanation on the opening and closing of the
discharging outlet 340 will be avoided for the brevity of the
description.
[0052] Further, the contaminant backflow prevention device includes
space adjusting means 400 mounted on the incised portion 350 to

prevention straw 10 may be of course different from the
above-mentioned assembling process.
[0061] Next, an explanation on the process of drinking the beverage
using the contaminant backflow prevention device 100 having the
contaminant backflow prevention straw 10 will be given.
[0062] If the discharging portion 30 of the contaminant back flow
prevention straw 10 is inserted into a user's mouth and then pulls,
the beverage accommodated in the container 200 is sucked to the
user s mouth through the sucking portion 20 and the discharging
portion 30.
[0063] At this time, the guide blocking shield 60 blocks the
passage of the sucking portion 20 before the user's sucking
operation, but if the discharging portion 30 pulls to allow the
beverage accommodated in the container 200 to be sucked to the
user's mouth, the guide blocking shield 60 blocks the passage of
the contaminant discharging portion 40 to allow the sucking portion
20 and the discharging portion 30 to communicate with each other by
means of the sucking force applied from the discharging portion 30,
the flow of air circulating the extension portion 70, and the
sucking force pulling from the contaminant discharging portion
40.
[0064] If the discharging portion 30 free from his or her lips, the
beverage contained in has or her mouth or the discharging portion
30 is stored in the storage space 320 of the case 300 through the
discharging portion 30 and the contaminant discharging portion
40.
[0065] At this time, the guide blocking shield 60 blocks the
passage of the sucking portion 20 to allow the discharging portion
30 and the contaminant discharging portion 40 to communicate with
each other by means of sucking force applied from the interior of
the container 200, the sucking force of air circulating the
extension portion 70, and the pressure applied from the discharging
portion 30.
[0066] Under the above-mentioned operation, the beverage
accommodated in the container can be easily drunk through the
contaminant backflow prevention device having the contaminant
backflow prevention straw, while the beverage in which the
contaminants are contained due to the backflow thereof is being
discharged to the outside.
[0067] While the present invention has been described with
reference to the particular illustrative embodiments, it is not to
be restricted by the embodiment but only by the appended claims. It
is to be appreciated that those skilled in the art can change or
modify the embodiments without departing from the scope and spirit
of the present invention.
