BACKGROUND ART

In general, when a person drinks milk, beverage or water in a glass or a can, he or she drinks directly from the glass or the can, but frequently drinks milk, beverage or water contained in the glass or the can using a straw.

Such a straw has an inner hollow portion. So, when a user sucks milk, beverage or water through the straw using a suction force after putting an upper portion of the straw into his or her mouth, the milk, beverage or water is sucked through a lower portion of the straw, such that the user can drink the milk, beverage or water.

Moreover, there are two kinds of straws: one being a straight straw; and the other being a bellows straw of which the upper part is bendable due to a bellows tube formed at the upper part.

In order to drink beverage using such a straw, first, the user puts the long lower portion of the straw into a beverage container, in which the beverage is contained, and then, sucks the beverage through the straw while holding the straw in his or her mouth, such that the user can drink the beverage contained in the beverage container by sucking the beverage through the straw.

In the meantime, such a conventional straw has an outer body sealed by an elongated main body and the hollow inner portion, and is made of synthetic resin.

Therefore, the conventional straw has several disadvantages in that it is disposed as garbage once it is used because it is impossible to be washed, in that it contaminates environment because it is not recovered and recycled and is thrown on a mountain, a hill or a pleasure garden as it is, and in that it causes a considerable economic loss due to waste and import of raw materials.

MODE FOR INVENTION

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

In the following description, the same elements will be designated by the same reference numerals although they are shown in different drawings.

Further, in the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Moreover, in the entire specification of the present disclosure, when any portion “includes” or “comprises” any component, this does not exclude other components but means that any other component can be further included, unless stated otherwise.

Hereinafter, in the drawings, for better understanding of the present invention, a horizontal to vertical ratio of the straw is ignored and a horizontality is expressed exaggeratedly.

FIGS. 1A and 1B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a first preferred embodiment of the present invention.

As shown in FIGS. 1A and 1B, the washable straw 100 according to the first preferred embodiment of the present invention includes a side body 110, connective joints 120, and detachment means 130.

The side body 110 has a predetermined thickness and is elongated vertically, and includes a plurality of side bodies 110a, 110b and 110c.

The connective joints 120 are made of a flexible material and connect the plural side bodies 110a, 110b and 110c with one another, such that air or beverage does not leak between the side bodies 110a, 110b and 110c and the plural side bodies 110a, 110b and 110c can be rolled circularly.

In this instance, the side body 110 and the connective joint 120 may be formed integrally, that is, the side body 110 made of a thick synthetic resin material extends to the connective joint 120 made of a think synthetic resin material.

Moreover, the plural side bodies 110a, 110b and 110c of the side body 110 may be made of a stainless steel material and the connective joints 120 made of a flexible material are connected between the plural side bodies 110a, 110b and 110c, such that the side bodies can be rolled circularly.

The detachment means 130 is disposed at both of the outermost side bodies 110a and 110b among the plural side bodies connected by the connective joints 120, namely, both side bodies 110a and 110b, which are not connected by the connective joints 120 and are separated, such that the separated side bodies 110a and 110b are detachable. Therefore, when the side bodies 110a, 110b and 110c are rolled circularly till the both side bodies 110a and 110b overlap each other, the detachment means 130 maintains a close contact state between the side bodies 110a and 110b so as to prevent a leak of air or beverage. According to the first preferred embodiment of the present invention, the detachment means 130 is a snap button type detachment means 130, and includes a fastening protrusion 131a and a fastening groove 131b.

That is, one side body 110a of both side bodies 110a and 110b has the fastening protrusion 131a, and the other one 110b has the fastening groove 131b formed at the position corresponding to the fastening protrusion 131a, such that both side bodies 110a and 110b overlap each other and come into close contact with each other when the fastening protrusion 131a is fit into the fastening groove 131b.

On the contrary to the above, one side body 110b of both side bodies 110a and 110b has the fastening protrusion 131a, and the other one 110a has the fastening groove 131b formed at the position corresponding to the fastening protrusion 131a, such that both side bodies 110a and 110b overlap each other and come into close contact with each other when the fastening protrusion 131a is fit into the fastening groove 131b.

In this instance, the inner diameter of the fastening groove 131b is equal to or a bit smaller than the thickness of the fastening protrusion 131a, such that the fastening protrusion 131a is forcedly fit into the fastening groove 131b and the fitting state is not released.

In the drawings, for instance, there are five side bodies 110 and two fastening protrusions 131a and two fastening grooves 131b, but of course, the present invention is not limited to the number of the components.

Due to such a configuration of the washable straw 100, the washable straw 100 can be used as a straw for drinking beverage by being put into a container like a glass in a state where a lateral side of a hollow portion 140 is sealed as shown in FIG. 1B, and after being used, is opened as shown in FIG. 1A, such that the inside of the straw 100 can be washed cleanly.

FIGS. 2A and 2B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a second preferred embodiment of the present invention.

As shown in FIGS. 2A and 2B, the washable straw 100 according to the first preferred embodiment of the present invention includes a side body 110, connective joints 120, and detachment means 130.

The side body 110 has a predetermined thickness and is elongated vertically, and includes a plurality of side bodies 110a, 110b and 110c.

The connective joints 120 are made of a flexible material and connect the plural side bodies 110a, 110b and 110c with one another, such that air or beverage does not leak between the side bodies 110a, 110b and 110c and the plural side bodies 110a, 110b and 110c can be rolled circularly.

In this instance, the side body 110 and the connective joint 120 may be formed integrally, that is, the side body 110 made of a thick synthetic resin material extends to the connective joint 120 made of a think synthetic resin material.

Moreover, the plural side bodies 110a, 110b and 110c of the side body 110 may be made of a stainless steel material and the connective joints 120 made of a flexible material are connected between the plural side bodies 110a, 110b and 110c, such that the side bodies can be rolled circularly.

The detachment means 130 is disposed at both of the outermost side bodies 110a and 110b among the plural side bodies connected by the connective joints 120, namely, both side bodies 110a and 110b, which are not connected by the connective joints 120 and are separated, such that the separated side bodies 110a and 110b are detachable. Therefore, when the side bodies 110a, 110b and 110c are rolled circularly till the both side bodies 110a and 110b overlap each other, the detachment means 130 maintains a close contact state between the side bodies 110a and 110b so as to prevent a leak of air or beverage. According to the first preferred embodiment of the present invention, the detachment means 130 is a Velcro type detachment means 130, and includes Velcro tapes 132a and 132b.

That is, one side body 110a of both side bodies 110a and 110b has the Velcro tape 131a formed on the inner surface thereof, and the other one 110b has the Velcro tape 131b formed on the outer surface thereof, such that both side bodies 110a and 110b overlap each other and come into close contact with each other when both Velcro tapes 132a and 132b are adhered to each other.

On the contrary to the above, one side body 110a of both side bodies 110a and 110b has the Velcro tape 131a formed on the outer surface thereof, and the other one 110b has the Velcro tape 131b formed on the inner surface thereof, such that both side bodies 110a and 110b overlap each other and come into close contact with each other when both Velcro tapes 132a and 132b are adhered to each other.

In the drawings, for instance, there are five side bodies 110 and the Velcro tapes 132a and 132b are respectively formed on the entire outer surface and the entire inner surface of the side bodies 110a and 110b, but of course, the present invention is not limited to the above.

Due to such a configuration of the washable straw 100, the washable straw 100 can be used as a straw for drinking beverage by being put into a container like a glass in a state where a lateral side of a hollow portion 140 is sealed as shown in FIG. 2B, and after being used, is opened as shown in FIG. 2A, such that the inside of the straw 100 can be washed cleanly.

FIGS. 3A and 3B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a third preferred embodiment of the present invention.

In the third preferred embodiment of the present invention, only the detachment means 130 will be described because the third embodiment is different only in the detachment means 130 from the second embodiment.

In the third embodiment, the detachment means 130 is a magnet type detachment means 130, and includes thin magnets 133a and 133b.

That is, like the Velcro tapes 132a and 132b of the second preferred embodiment, one side body 110a of both side bodies 110a and 110b has the magnet 133a formed on the inner surface thereof, and the other one 110b has the magnet 133b formed on the outer surface thereof, such that both side bodies 110a and 110b come into close contact with each other when both magnets 133a and 133b are adhered to each other by a magnetic force.

On the contrary to the above, one side body 110a of both side bodies 110a and 110b has the magnet 133a formed on the outer surface thereof, and the other one 110b has the magnet 133b formed on the inner surface thereof, such that both side bodies 110a and 110b come into close contact with each other when both magnets 133a and 133b are adhered to each other by a magnetic force.

Alternatively, as shown in FIGS. 3A and 3B, the thin magnets 133a and 133b may be respectively embedded in the side bodies 110a and 110b instead of being adhered on both side bodies 110a and 100b.

FIGS. 4A and 4B are plan views of detachment means of a washable straw according to a fourth preferred embodiment of the present invention.

In the fourth embodiment, the detachment means 130 is a hanger type detachment means 130, and includes holding members 134a and 134b and hook members 135a and 135b.

In the case of the straw having hanger type detachment means 130, the straw does not include the connective joints 120 but includes an integrated side body 110.

The integrated side body 110 is made of a synthetic resin material or a stainless steel material, which is capable of maintaining the basic form of a nearly circular shape due to its good elasticity.

In FIG. 4A, the holding members 134a and 134b are formed at both ends of the integrated side body 110 to correspond to each other. Therefore, when a user presses the integrated side body 110 of an elastic body at the left and right of the drawings, while both ends of the integrated side body 110 are retracted inwardly, the holding members 134a and 134b intercross each other and are caught together to retaining jaws of the holding members 134a and 134b so as to seal the lateral side.

FIGS. 5A and 5B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a fifth preferred embodiment of the present invention.

In the fifth preferred embodiment of the present invention, only the detachment means 130 will be described because the fifth preferred embodiment is different in the detachment means 130 and the number of the side bodies from the second preferred embodiment. In the fifth preferred embodiment, the washable straw has four side bodies.

Due to the difference in the number of the side bodies 110, the outermost side bodies 110a and 110b do not overlap each other but lateral end portions of the side bodies 110a and 110b get in contact with each other.

In the fifth preferred embodiment, the detachment means 130 is a zipper type detachment means, and includes teeth parts 136a and 136b and a slider 136c.

That is, the outermost side bodies 110a and 110b among the four side bodies 110a, 110b and 110c connected by the connective joints 120, namely, the side bodies 110a and 110b, which are not connected by the connective joints 120 and are separated, respectively have the teeth parts 136a and 136b mounted vertically, and the slider 136c is combined to one 136c of the teeth parts.

The teeth parts 136a and 136b are combined to each other or separated from each other according to movement of the slider 136c, such that the lateral end portions of the side bodies 110a and 110b are sealed by coming into contact with each other or are opened.

FIGS. 6A and 6B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a sixth preferred embodiment of the present invention.

In the sixth preferred embodiment of the present invention, only the detachment means 130 will be described because the fifth preferred embodiment is different in the detachment means 130 and the number of the side bodies from the second preferred embodiment.

In the sixth preferred embodiment, the detachment means 130 is a connection type detachment means, and includes connection protrusions 137a and connection slots 137b.

That is, one 110a of the outermost side bodies 110a and 110b among the four side bodies 110a, 110b and 110c connected by the connective joints 120 has the connection protrusions 137a protruding outwardly, and the other one 110b, which is formed to extend outwardly longer than the width of the side body 110a, has the connection slots 137b formed at the extended part, such that the connection protrusions 137a can be forcedly fit into the connection slots 137b.

Thereby, in the state where the end portions of the side bodies 110a and 110b get in contact with each other, the connection protrusions 137a are forcedly fit into the connection slots 137b to seal the lateral side.

In this instance, because the size of the connection protrusion 137a is larger than or equal to the size of the connection slots 137b, the connection protrusions 137a are not separated from the connection slots 137b well once they are forcedly fit into the connection slots 137b.

FIG. 7 is a plan view of a washable straw according to a seventh preferred embodiment of the present invention.

As shown in FIG. 7, the washable straw 100 according to the seventh preferred embodiment of the present invention includes a side body 110, connective joints 120, and detachment means 130.

The side body 110 has a predetermined thickness, is elongated vertically, and includes a plurality of side bodies 110a, 110b and 110c.

The connective joints 120 are made of a flexible material and connect the plural side bodies 110a, 110b and 110c with one another, such that air or beverage does not leak between the side bodies 110a, 110b and 110c and the plural side bodies 110a, 110b and 110c can be rolled circularly.

In this instance, the side body 110 and the connective joint 120 may be formed integrally, that is, the side body 110 made of a thick synthetic resin material extends to the connective joint 120 made of a think synthetic resin material.

Moreover, the plural side bodies 110a, 110b and 110c of the side body 110 may be made of a stainless steel material and the connective joints 120 made of a flexible material are connected between the plural side bodies 110a, 110b and 110c, such that the side bodies can be rolled circularly.

Furthermore, in the seventh preferred embodiment, a connective joint 120′, which has nearly the same thickness as the side bodies 110b and 110c, may be connected between the side bodies 110b and 110c.

The connection type detachment means 130 is disposed at the outermost side body 110a among the plural side bodies, which are connected by the connective joints 120 and 120′, and at the connective joint 120′. Therefore, in the state where the side bodies 110a and 110b overlap each other when the plural side bodies 110a, 110b and 110c are rolled, the connection type detachment means 130 maintains a close contact state between the side bodies 110a and 110b so as to prevent a leak of air or beverage. According to the seventh preferred embodiment of the present invention, the connection type detachment means 130 includes a circular protrusion 138a and a circular recess 138b.

In other words, the circular protrusion 138a is formed at a lateral end portion of one side body 110a, and the circular recess 138b, whose entrance is narrow but inside is wide, is inwardly formed at the connective joint 120′, such that the side bodies 110a and 110b overlap each other and are tightly mated with each other when the circular protrusion 138a is fit into the circular recess 138b from the outside.

On the contrary, the circular protrusion 138a may be formed at the connective joint 120′ and the circular recess 138b may be formed at the side body 110a.

FIGS. 8A and 8B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to an eighth preferred embodiment of the present invention.

As shown in FIGS. 8A and 8B, the washable straw 100 according to the eighth preferred embodiment of the present invention includes a side body 110, a connective joint 120, and detachment means 130.

The side body 110 has a predetermined thickness, is formed in a semicircular shape, and is formed to be elongated vertically. The side body 110 includes two semicircular side bodies 110d and 110e.

The connective joint 120 is made of a flexible material, and connects between the two semicircular side bodies 110d and 110e to prevent a leak of air or beverage between the semicircular side bodies 110d and 110e and freely move between the two semicircular side bodies 110d and 110e.

Additionally, in the eighth preferred embodiment, the connection type detachment means 130 disposed between the two semicircular side bodies 110d and 110e prevents a leak of air or beverage by maintaining the close contact state between the lateral end portions of the two semicircular side bodies 110d and 110e when the lateral end portions of the two semicircular side bodies 110d and 110e come into contact with each other. In the eighth preferred embodiment, the detachment means 130 includes a circular protrusion 138a and a circular recess 138b.

In other words, the circular protrusion 138a is formed at the lateral end portion of one semicircular side body 110d, and the circular recess 138b, whose entrance is narrow but inside is wide, is inwardly formed at the lateral end portion of the other semicircular side body 110e, such that the lateral end portions of the semicircular side bodies 110d and 110e come in contact with each other and merge into each other when the circular protrusion 138a is fit into the circular recess 138b from the outside.

On the contrary, the circular protrusion 138a may be formed at the lateral end portion of the semicircular side body 110e and the circular recess 138b may be formed at the lateral end portion of the semicircular side body 110d.

FIGS. 9A and 9B are respectively a plan view of a washable straw and a perspective view of a spread state of the washable straw according to a ninth preferred embodiment of the present invention.

As shown in FIGS. 9A and 9B, the washable straw 100 according to the ninth preferred embodiment of the present invention includes an integrated side body 110 and detachment means 130.

The integrated side body 110 is made of a synthetic resin material, which is capable of maintaining the basic form of a nearly circular shape due to its good elasticity, or a soft material to be rolled circularly.

When the lateral portions of the integrated side body overlap each other, the connection type detachment means 130 disposed at the integrated side body 110 maintains a contact state of the overlap portion so as to prevent a leak of air or beverage. In the ninth preferred embodiment, the connection type detachment means 130 includes a plurality of circular protrusions 138a and a plurality of circular recesses 138b.

In other words, the circular protrusions 138a are vertically arranged on the inner surface near to one end side of the integrated side body 110, and the circular recesses 138b, each of which entrance is narrow but inside is wide, are inwardly formed on the outer surface near to the other end side of the integrated side body to correspond to the circular protrusions 138a. Therefore, both sides of the integrated side body, which is formed in a circular shape when the circular protrusions 138a are fit into the circular recesses 138b one to one from the outside, are tightly mated with each other while partially overlapping each other.

FIGS. 10A and 10B are respectively a perspective view of a spread state and a perspective view of an assembled state of a washable straw according to a tenth preferred embodiment of the present invention.
