BOTTLE

1 . A bottle having a neck portion and a body portion for containing liquid contents therein, the body portion comprising:

a plurality of guides formed around at least partial area or an entire area of the body portion in a spiral pattern, the guides protruding inwards from an inner surface of the body portion to have convex shapes, so that the liquid contents are guided towards an opening of the neck portion while spirally revolving inside the body portion; and

at least one reinforcing wire provided in the plurality of guides to reinforce an upright strength of the body portion formed with the plurality of guides.

2 . The bottle as set forth in claim 1 , wherein when the guides are formed in the entire area of the body portion including an upper area and a lower area based on a midpoint of the body portion, an outer surface of the lower area of the body portion has an uneven surface formed by the guides, and an inner surface of the lower area thereof has a planar shape.

3 . The bottle as set forth in claim 1 , wherein the convex shape of each of the guides is streamlined or angled.

4 . The bottle as set forth in claim 3 , wherein

when the convex shape of each of the guides is streamlined,

a cross-section of the guide protruding inwards from the inner surface of the body portion has a shape of a letter “C” or a reversed letter “C”, wherein a curvature of the guide is uniform or changes in a manner such that a curvature of a leading portion thereof is smaller than a curvature of a tailing portion with respect to a direction in which the liquid contents are discharged, and the guide spirals in either of the clockwise or counterclockwise directions.

5 . The bottle as set forth in claim 3 , wherein

when the convex shape of each of the guides is angled,

a cross-section of the guide has an angled shape of “>” or “<”, and the guide spirals in either of the clockwise or counterclockwise directions.

6 . The bottle as set forth in claim 1 , wherein the reinforcing wire extends in direction parallel to a longitudinal axis of the body portion formed with the plurality of guides or in a direction inclined at a predetermined angle with respect to the longitudinal axis of the body portion.

7 . The bottle as set forth in claim 6 , wherein the reinforcing wire comprises a plurality of reinforcing wires each of which is shorter than the body portion formed with the plurality of guides, wherein the reinforcing wires are discontinuous.

8 . The bottle as set forth in claim 6 , wherein a cross-section of the reinforcing wire has a square shape, a rectangular shape, a semicircular shape or a triangular shape such that a width thereof is reduced from a side contacting the guides to a side protruding inwards from the guides.

9 . The bottle as set forth in claim 8 comprising a paper bottle, a PET bottle, a metal bottle or a glass bottle.

10 . The bottle as set forth in claim 9 , wherein each of the plurality of guides is configured such that a width thereof in the lower area of the body portion is greater than a width thereof in the upper area of the body portion, and

a depth of the guide in the upper area of the body portion is greater than a depth thereof in the lower area of the body portion.

11 . The bottle as set forth in claim 9 , wherein each of the plurality of guides has a uniform width in the upper area and the lower area of the body portion, and

a depth of the guide in the upper area of the body portion is greater than a depth thereof in the lower area of the body portion.

12 . The bottle as set forth in claim 2 , wherein the reinforcing wire extends in direction parallel to a longitudinal axis of the body portion formed with the plurality of guides or in a direction inclined at a predetermined angle with respect to the longitudinal axis of the body portion.

13 . The bottle as set forth in claim 3 , wherein the reinforcing wire extends in direction parallel to a longitudinal axis of the body portion formed with the plurality of guides or in a direction inclined at a predetermined angle with respect to the longitudinal axis of the body portion.

14 . The bottle as set forth in claim 4 , wherein the reinforcing wire extends in direction parallel to a longitudinal axis of the body portion formed with the plurality of guides or in a direction inclined at a predetermined angle with respect to the longitudinal axis of the body portion.

15 . The bottle as set forth in claim 5 , wherein the reinforcing wire extends in direction parallel to a longitudinal axis of the body portion formed with the plurality of guides or in a direction inclined at a predetermined angle with respect to the longitudinal axis of the body portion.
