The present invention relates to a straw and a manufacturing method thereof.

A straw is a tool that is inserted into liquid beverages such as water and beverages to suck it in the mouth.

A generally used straw is formed into a hollow cylindrical shape. In the case of such a conventional straw, there is a problem that the warm beverage is cooled in the course of passing through the straw, or the temperature rises in the process of passing the cold beverage through the straw, thereby losing a cooling sensation.

An object of the present invention is to provide a straw capable of adjusting the temperature of a beverage to be sucked according to the user's taste.

Another object of the present invention is to provide a straw capable of maintaining a refreshing sensation of a beverage in the process of sucking the beverage.

A straw according to the present invention includes: an outer body formed in an empty space in an interior and extending in a predetermined direction; And an inner body which is provided inside the outer body and extends in the same direction as the outer body, and a spiral-shaped flow path is provided between the outer body and the inner body so that a fluid can flow.

A method of manufacturing a straw according to the present invention includes the steps of: producing an outer body having a hollow space formed therein; Producing an inner body of a predetermined cross-sectional area; Forming a depression extending spirally on an outer circumferential surface of the inner body; Injecting an inner material capable of heat exchange with the beverage into the inner body; Cooling or heating the inner body into which the inner material is injected; And inserting the inner body having the depression into the inner body.

According to the present invention, when the cold beverage is sucked, the beverage is cooled while passing through the straw, thereby enhancing the cooling sensation of the user.

According to the present invention, the temperature of the beverage sucked by the straw can be adjusted to a user-desired temperature by a simple method.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. It should be understood, however, that the spirit of the present invention is not limited to such embodiments, and that the spirit of the present invention may be proposed differently from addition, modification and deletion of elements constituting the embodiments, .

FIG. 1 is a perspective view of a straw according to a first embodiment of the present invention, FIG. 2 is an exploded perspective view of a straw according to a first embodiment of the present invention, FIG. 3 is a perspective view of a straw according to the first embodiment of the present invention, Fig. 4 is a plan view of a straw according to the first embodiment of the present invention. Fig.

1 to 4, a straw 1 according to an embodiment of the present invention includes an outer body 20 and an inner body 10 disposed inside the outer body 20.

The outer body 20 is a part forming the external shape of the straw 1. The outer body 20 may be formed in a cylindrical shape having a hollow interior and an elongated shape. The length and diameter of the outer body 20 can be variously selected depending on the application in which the straw 1 is used.

For example, when the container containing the beverage sucked by the straw 1 is deep, the length of the outer body 20 may be long, and the beverage sucked by the straw 1 may be viscous, The diameter of the outer body 20 can be increased when the floating body is floating in the beverage.

A space slightly larger than at least the inner body 10 may be formed in the outer body 20 so that the inner body 10 can be received.

The outer body 20 is preferably made of a light material so that a person who sucks the drink can easily drink it. For example, the outer body 20 may be formed of a plastic material.

In addition, the outer body 20 may be made of a transparent material so that the inner drink can be seen from the outside.

The inner body 10 is inserted into an empty space inside the outer body 20. The inner body 10 may be formed in a cylindrical shape having a depression 11 on the outer circumferential surface thereof. The inner body 10 may be extended in a direction parallel to the direction in which the outer body 20 extends in a state where the inner body 10 is inserted into the outer body 20.

The length of the inner body 10 may be the same as the length of the outer body 20 or slightly shorter than the length of the outer body 20. However, it is not preferable that the length of the inner body 10 is longer than that of the outer body 20 and protrudes outside the outer body 20.

The diameter of the inner body 10 is formed to be slightly smaller than the diameter of the inner circumferential surface of the outer body 20 so that the inner body 10 can be fitted into the outer body 20 in an interference fit manner.

Therefore, when the inner body 10 is inserted into the outer body 20, the outer circumferential surface of the inner body 10 can be brought into close contact with the inner circumferential surface of the outer body 20.

The depressed portion 11 formed on the outer peripheral surface of the inner body 10 is recessed by a predetermined depth on the outer peripheral surface of the inner body 10.

The depressed portion 11 may be formed in a spiral shape along the longitudinal direction of the inner body 10. That is, the depressed portion 11 can be extended while being wound along the longitudinal direction in which the inner body 10 extends.

A plurality of depressions 11 may be formed on the outer circumferential surface of the inner body 10. In this embodiment, the depressions 11 are formed on the outer circumferential surface of the inner body 10 at intervals of 120 degrees . The dimples 11 may be formed at regular intervals around the inner body 10 because the beverage can be heat-exchanged in a balanced manner if the dimples 11 are formed at regular intervals.

A portion of the outer circumferential surface of the inner body 10 excluding the portion where the depressed portion 11 is formed may protrude relative to the depressed portion 11. The portion of the outer peripheral surface of the inner body 10 protruding relative to the depressed portion 11 may be referred to as the protruding portion 12.

The protruding portion 12 is a portion which is brought into close contact with the inner circumferential surface of the outer body 20 when the inner body 10 is inserted into the outer body 20.

The inner surface of the protrusion 12 and the inner surface of the outer body 20 may be joined by an adhesive. However, as described above, the inner body 10 may be coupled to the inner surface of the outer body 20 have.

When the inner body 10 is coupled to the outer body 20, the depression 11 serves as a channel through which the beverage flows.

When a person using the straw 1 sucks the beverage after the straw 1 is inserted into the beverage, the beverage flows through the depression 11. That is, the beverage being sucked flows through a spiral flow path formed between the inner body 10 and the outer body 20, and more specifically, the outer peripheral surface of the inner body 10 spirally rotates upward Flows.

The inside of the inner body 10 can receive an inner material capable of heat exchange with the beverage flowing in the depression 11.

The inner material may lower the temperature of the beverage flowing through the depression 11 to cool the beverage or raise the temperature of the beverage flowing through the depression 11 to make the beverage more hot.

It is preferable to use a substance harmless to the human body such as water or saline solution.

Further, if the temperature of the internal material changes too fast, it is inconvenient to cool or heat the straw 1 again after use. Therefore, it is preferable to use a substance having a high specific heat.

In order to cool the beverage flowing through the depression 11, the inner body 10 may be cooled with the inner material included therein.

For this, the inner body 10 may be coupled to the outer body 20 after being accommodated in the refrigerator or the freezer room for a predetermined time while the inner material is received.

On the other hand, in order to heat the beverage flowing through the depression 11, the inner body 10 can be heated in a state including the inner material.

To this end, the inner body 10 may be coupled to the outer body 20 after being accommodated in the hot water for a predetermined time while the inner material is received.

Since the inner material and the beverage flowing through the depression 11 perform heat exchange through the inner body 10, the inner body 10 is preferably made of a material having a high heat transfer coefficient. For example, the inner body 10 may be formed of a light metal material having a high heat transfer coefficient. Of course, in this case, the inner body 10 is preferably made of a metal which is harmless to the human body.

When the beverage flows spirally around the inner body 10, the beverage is more likely to be in contact with the outer peripheral surface of the inner body 10 than when the beverage flows straightly around the inner body 10, And the contact time with the outer peripheral surface of the inner body 10 becomes longer.

The contact area between the inner body 10 and the beverage is about 14 to 20 mm, as compared with the case where the depression 11 is formed in a spiral shape, assuming that the length of the straw 1 is the same, 15% increase.

Therefore, compared with the case where the depressed portion 11, that is, the case where the flow path of the beverage flows spirally is formed in a straight line, the area and time that the beverage is heat-exchanged with the internal substance in the inner body 10 is larger Therefore, there is an advantage that the beverage can be cooled or heated more efficiently.

An injection hole for injecting the internal material may be formed in the inner body 10 to periodically replace the internal material. In this case, an opening / closing part capable of selectively opening and closing the injection hole may be provided.

 Alternatively, the inner body 10 may be sealed in a state accommodating the inner material.

The inner body 10 can form the depression 11 on the outer circumferential surface by an extrusion method. In order to manufacture the inner body 10, the cylindrical body is rotated, and a shape corresponding to the depressed portion 11 is pushed into a circular mold protruding into the inner portion. The depressed portion 11 is formed on the outer peripheral surface, The inner body 10 can be manufactured.

As the inner body 10 is manufactured by the extrusion method, the productivity of the straw 1 is improved.

Also, the depressed portion 11 of the inner body 10 may be formed by twisting a cylindrical object. That is, when one end of the cylindrical object is fixed and the other end of the cylindrical object is rotated, the cylindrical object is twisted to form the depression 11.

Hereinafter, a straw according to a second embodiment of the present invention will be described. Since the shape of the straw according to the second embodiment of the present invention differs from that of the straw according to the first embodiment of the present invention, except for the difference from the straw according to the first embodiment, The description of the embodiments will be used herein.

5 is a side view of a straw according to a second embodiment of the present invention.

5, the straw 2 according to the present embodiment includes an outer body 40 forming an outer shape of the straw 2 and an inner body 30 inserted into the outer body 40 .

The outer body 40 is divided into an inner body receiving portion 41 into which the inner body 30 is inserted and an inner body receiving portion 42 into which the inner body 30 is not inserted. For convenience, the inner body receiving portion 41 may be referred to as a first body, and the inner body unreceiving portion 42 may be referred to as a second body.

The depression 31 in which the beverage can flow and the protrusion 32 except the depression 31 are formed in the inner body 30 are the same as those in the first embodiment.

Since the inner body receiving portion 41 accommodates the inner body 30 therein, the inner body receiving portion 41 may be formed larger in diameter than the inner body receiving portion 42.

A step may be formed at the boundary between the inner body receiving portion 41 and the inner body receiving portion 42 due to the difference in diameter between the inner body receiving portion 41 and the inner body receiving portion 42 have.

The inner body non-receiving portion 42 may be formed in a cylindrical shape having a space through which drinks can flow. That is, the inner body non-receiving portion 42 may be formed in a tube shape.

When the upper end of the inner body receiving portion 41 is pulled in a state where the inner body receiving portion 42 is plugged into the drink, the beverage comes up through the inner space of the inner body receiving portion 42, Through the depression (31) of the inner body (30) received in the inner body receiving portion (42).

 When the beverage passes through the inner body receiving portion 41, the beverage may cause heat exchange with the inner material accommodated in the inner body 30.

The straw 2 is mainly used to prevent an initial burn when sucking hot drinks.

In detail, the inner body 30 is cooled and contains a low-temperature inner material. When the inner body receiving portion 42 is in contact with the high-temperature beverage, the inner- The high-temperature beverage is first raised through the inner body receiving portion 42 and then moved along the depressed portion 31 of the inner body 30 received in the inner body receiving portion 41 Coming up.

Since the beverage is cooled by the internal material contained in the inner body 30 while the beverage flows through the depression 31, the temperature is lowered, so that the person who sucks the beverage suddenly burns in the mouth due to the hot beverage .
