Description

The present invention relates to a straw for use when drinking hot drinks such as coffee and tea.

Conventionally, when drinking hot drinks, open a vent on the outer peripheral surface of an elongated cylindrical straw, adjust the opening and closing of the vent by expansion and contraction of the bent part, and introduce a variable amount of outside air to hot drink You can drink chilled.

JP-A-2002-253414 (P2002-253414A) (first page, FIG. 1)

The conventional techniques have the following problems.
Problem 1, the drink leaks out from the vents while drinking, resulting in disgust and a problem with hygiene. Problem 2, the air from the air vents vibrates the drink, makes a loud voice and disturbs others. Problem 3, when expanding / contracting the bent portion, the problem 1 is further deteriorated.

In order to solve the above problems, the present invention takes the following means.
Establish an air route next to the launch channel. Prepare a barrier that can be attached to the airway so that the airway itself can be attached.

According to the first aspect of the present invention, the airway is separated from the waterway, there is no leakage of the drink, and there is no vibration of the drink due to air, and no voice is produced when drinking.

According to the second aspect of the invention, in addition to having the configuration of the first aspect of the invention, a freely installable blocking object is installed to achieve the effect of the first aspect of the invention and The amount of heat can be adjusted, and the amount of heat that the drink cools down can be adjusted according to the amount of advancement.

According to the invention according to claim 3, after having the configuration of the invention according to claim 1, the amount of advance can be adjusted by another method so that the air passage itself can be freely mounted, The effect of the second aspect can be obtained.

Hereinafter, embodiments of the present invention will be described in detail based on examples.

(First Embodiment) FIG. 1 schematically illustrates a basic configuration according to a first embodiment of the present invention. Next to the launching channel 1, an airway 2 is provided. Launch channel 1 and air channel 2 are completely partitioned. Water does not enter into the airway 2 from the waterway 1. Air cannot enter airway 2 from airway 2. One or more vent holes 3 are provided on the outer peripheral surface of the air passage 2. When drinking a hot drink, the hot drink enters the mouth through the launch channel 1, air enters through the vent 3, enters the mouth through the advance channel 2, and cools the hot drink. The blocker 4 adjusts the amount of air that enters the airway 2 by partially or completely blocking the vent hole 3, thereby adjusting the amount of heat that is dropped by the hot drink. FIG. 2 is a perspective view showing the internal structure of the first embodiment of the present invention. FIG. 3 is a perspective view when the blocking object 4 according to the first embodiment of the present invention blocks all the air holes 3. FIG. 4 is a perspective view in the case where the blocking object according to the first embodiment of the present invention blocks a portion of the vent hole.

(Second Embodiment) FIG. 5 schematically illustrates a basic configuration according to a second embodiment of the present invention. An annular airway 5 is provided around the waterway 1. The launch channel 1 and the annular channel 5 are completely partitioned. Water cannot enter the circular airway 5 from the waterway 1. Air cannot enter the launching channel 1 from the annular airway 5. One or more vent holes 3 are provided on the outer peripheral surface of the annular air passage 5. When drinking a hot drink, the hot drink enters the mouth through the launch channel 1, air enters through the vent 3, enters the mouth through the annular channel 5, and cools the hot drink. The blocker 4 adjusts the amount of hot drink that falls by adjusting the amount of air entering the annular airway 5 by partially or completely blocking the vent hole 3. FIG. 6 is a perspective view showing the internal structure of the second embodiment of the present invention.

(Third Embodiment) FIG. 7 schematically illustrates a basic configuration according to a third embodiment of the present invention. A bowl-shaped airway 6 is provided around the waterway 1. The launch channel 1 and the saddle-like air channel 6 are completely partitioned. No water can enter the bowl-shaped airway 6 from the waterway 1. Air cannot enter the launch channel 1 from the saddle-like air channel 6. One or more vent holes 3 are provided on the outer peripheral surface of the bowl-shaped airway 6. When drinking a hot drink, the hot drink enters the mouth through the launch channel 1, air enters through the vent 3, enters the mouth through the bowl-like channel 6, and cools the hot drink. The blocker 4 adjusts the amount of air that enters the bowl-like airway 6 by partially or completely blocking the vent hole 3, thereby adjusting the amount of heat that is dropped by the hot drink. The bowl-shaped airway 6 can be freely mounted on the waterway 1. If the bowl-like airway 6 is not installed, air does not enter the mouth when drinking a hot drink, and the heat of the hot drink does not drop. FIG. 8 is a perspective view showing a saddle-shaped airway 6 according to a third embodiment of the present invention. FIG. 9 is a perspective view showing the internal structure of the third embodiment of the present invention.

(Fourth Embodiment) FIG. 10 schematically illustrates a basic configuration according to a fourth embodiment of the present invention. One or more side airways 7 are provided near the waterway 1. The launch channel 1 and the side airway 7 are completely separated. Water cannot enter the side airway 7 from the waterway 1. Air cannot enter airway 1 from side airway 7. One or more vent holes 3 are provided on the outer peripheral surface of the side air passage 7. When drinking a hot drink, the hot drink enters the mouth through the launch channel 1, air enters through the vent 3, enters the mouth through the side air passage 7, and cools the hot drink. The side airway 7 can be mounted on the side of the waterway 1. The amount of air entering the bypass air passage 7 is adjusted according to the number of the attached bypass air passages 7 to adjust the amount of hot drink that falls. When the side airway 7 is not attached, when drinking a hot drink, air does not enter the mouth, and the heat of the hot drink does not drop. FIG. 11 is a perspective view showing a side airway 7 according to the fourth embodiment of the present invention.
