## Background
BACKGROUND
1. Technical Field
The disclosure relates to water bottles, and, in particular, to a water bottle having a push button structure and a straw structure that can bounce up and be reset.
2. Description of Related Art
A traditional water bottle mainly comprises a bottle body and a cover. The bottle body has a container and an opening disposed on the top of the bottle body and being in communication with the container. The container is used for containing liquid, such as water or beverage. The bottle body has an external thread disposed on a periphery of the opening. The cover is used to cover the opening. The cover has an internal thread disposed on an inner side thereof that corresponds to the external thread, and can be engaged with the bottle body, such that the liquid contained in the container of the bottle body is prevented from leakage.
In order to facilitate the use of the water bottle, the cover generally will be further divided into two portions, including an upper cover and a lower cover. The lower cover is provided with the internal thread, and has a convex tube that is outward protruded and in communication with the container of the bottle body. The convex tube allows a user to suck the liquid in the bottle body or pour the liquid from the bottle body. The upper cover is used to cover the convex tube. The convex tube is generally designed to be a convex nozzle in the shape of a volcano. The lower cover, while in use, is normally fixed to the bottle body, and will be taken off only when more liquid needs to be filled in the bottle body. The upper cover has one end hinged on the lower cover, and the other end buckled on the lower cover through a buckle structure. A user may press the buckle structure and release the upper cover from the lower cover, so as to expose the convex tube. However, the buckle structure is likely loosened due to the vibration of the water bottle or the false touching by the user, and the liquid contained in container of the bottle body will leak therefrom, without being aware by the user.
Besides, the traditional water bottle generally has a straw additional installed. The straw has a bottom end at the bottom of the bottle body, and a head end extending out from the convex tube of the lower cover, for a user to suck the liquid in the water bottle. However, the straw is unlikely to be reset as a user opens the upper cover, and the head end of the straw cannot protrude from the convex tube smoothly. Accordingly, the user may need to make the straw out with his fingers, or adjust the position of the straw by unscrewing the lower cover, which may cause inconvenience to user.
In view of the above mentioned drawbacks, the traditional water bottle needs to be further improved.

The push button structure 113 comprises a body 140, a first buckle member 141, a second buckle member 142, and an elastic member 143. The body 140 has a top portion 151 and a bottom portion 152 opposing the top portion 151, an inner lateral portion 153, and an outer lateral portion 154 opposing the inner lateral portion 153. The inner lateral portion 153 and the outer lateral portion 154 are disposed between the top portion 151 and the bottom portion 152. The first buckle member 141 is located at the top portion 151. The second buckle member 142 is at the bottom portion 152. The elastic member 143 is located on the inner lateral portion 153. The first buckle member 141 is used to buckle the first cover 111. The second buckle member 142 is used to buckle the second cover 112. the elastic member 143 is used to bear against the second cover 112.
The first buckle member 141 includes an elastic arm 155, a cap 156, and a chamfer 157. The elastic arm 155 has one end connected to the top portion 151, and the other end connected to the cap 156. The cap 156 may be assembled with the elastic arm 155 to form a barbed structure. The chamfer 157 is formed between the top portion 151 and the elastic arm 155, and can increase the intensity of the structure. The cap 156 includes an enlarged round 158. The round 158 is formed on the side of the cap 156 back to the elastic arm 155. The second buckle member 142 includes two opposing and symmetric feet 159. The two feet 159 may each include an oblique hook 160. The two oblique hooks 160 are disposed at the ends of the two feet 159 that are distal to the bottom portion 152. The two oblique hooks 160 each have a slope 161 of increasing inclination on the outside surface of the oblique hook 160.
In an embodiment, as shown in FIG. 4A, the slopes 161 of the two oblique hooks 160 slightly protrude out of the two feet 159 to form a hook shape. In another embodiment, as be seen in FIG. 4B, the slopes 161 of the two oblique hooks 160 significantly protrude out of the two feet 159, and the second buckle member 142′ buckled with the second cover 122 as shown in FIG. 4B is more stable than the second buckle member 142 as shown in FIG. 4A. Therefore, the structure formed with the slopes 161 of the two oblique hooks 160′ is more prominent, and the more stable force can be provided by the second buckle member 142′ buckled with the second cover 112.
The outer lateral portion 154 of the body 140 has multiple convex bars 162. The convex bars 162 can increase the friction to enhance the feel. As shown in FIGS. 5, 6A and 6B, the elastic member 143 includes a slant plate 163. The slant plate 163 includes a fixed end and a free end. The fixed end is connected to the inner lateral portion 153. The slant plate 163 extends obliquely relative to the body 140 from the fixed end to the free end. In an embodiment, as seen in FIG. 6A, the slant plate 163 further includes a separation slot 164. The separation slot 164 extends from the free end to the fixed end and extends to the position between the free end and the fixed end. The slant plate 163 is divided into two separate branch plates 165 by the separation slot 164, and the width of the separation slot 164 is gradually decreased from the free end to the fixed end. In other words, the width of the two branch plates 165 is respectively gradually increased from the free end to the fixed end. The elastic member 143 further includes a fillet 166 that is formed between the slant plate 163 and the body 140.
The push button structure 113 is normally assembled to the second cover 112. During assembling, the body 140 is clamped by the two limiting walls 133, and the two feet 159 of the second buckle member 142 are inserted into the second buckle groove 134. When the two feet 159 are inserted into the second buckle groove, it will help to smooth the insertion because of the large angle of inclination of the slope 161, to facilitate assembly. As seen in FIG. 3, when the two feet 159 are inserted into the bottom of the second buckle groove 134, the two oblique hooks 160 will be stuck in the mismatches 135 of the two side walls in the second buckle groove 134, and the push button structure 113 can be fixed on the second cover 112. The elastic member 143 is used to bear against the second cover 112, and the first buckle member 141 of the push button structure 113 and the first buckle joint 122 of the first cover 111 can be buckled together or separated. A user can buckle the first cover 111 to the second cover 112 by covering the convex tube 125 by the first cover 111, such that the buckle plate 131 will be in contact with the first buckle member 141 of the first buckle groove 132, and the cap 156 will penetrate the first buckle groove 132 by exerting a force under pressure. After the cap 156 penetrates the first buckle groove 132, the elastic restoring force of the slant plate 163 and the branch plates 165 will push the body 140 outward. The barbed structure formed by the cap 156 and the elastic arm 155 is used to be buckled outwardly to the buckle plate 131 on the edge of the first buckle groove 132. The round 158 of the cap 156 will make the cap 156 penetrate through the first buckle groove 132 more smoothly.
A user can open the first cover 111 by pressing the outer lateral portion 154, such that the body 140 will move inwardly and be closer to the second cover 112. At the same time, the cap 156 will also move inwardly, the barbed structure formed by the cap 156 and the elastic arm 155 will be unbuckled to the buckle plate 131, and the cap 156 can be separated from the first buckle groove 132 by pulling the first cover 111 upward. The first cover 111 can be pivoted freely relative to the second cover 112. When the first buckle member 141 and the first buckle joint 122 are buckled together, the slant plate 163 and the branch plates 165 bear against the second cover 112 constantly. Accordingly, the elastic restoring force of the slant plate 163 and the branch plates 165 will push the body 140 outward constantly, such that the cap 156 will not be separated from the first buckle groove 132 even in the case of vibration of the bottle or the false touching on the outer lateral portion 154 by a user. It is ensured that the first buckle member 141 and the first buckle joint 122 will not be separated from each other in an unexpected situation. In an embodiment of the present disclosure, the slant plate 163 is further divided into two branch plates 165, so as to reduce the elastic restoring force, and allow a user to press the outer lateral portion 154 more easily. In another embodiment, the elastic member does not include the separation slot and the branch plates. Instead of providing a whole piece of slant plate directly bear against the second cover, such the elastic member can provide a greater elastic restoring force, and the cap can thus buckle with the first buckle groove more stably, the slant plate 163 as shown in FIG. 6B.
Please refer to FIGS. 7 and 8, the straw structure 21 is arranged in the bottle body 30 of the water bottle 1. The straw structure 21 includes an elongate tube 210, an elastic tube 220, and a nozzle tube 230. The elongate tube 210 includes a head end 211 and a tail end 212 opposing the head end 211 (referring to FIG. 8). The elastic tube 220 includes a sleeve joint 221 and a bottom portion 222 opposing the sleeve joint 221, and a neck portion 223.
Please refer to FIGS. 9 and 10. The elastic tube 220 is a silicone tube which is mainly made of silicone. The whole body is flexible. The elastic tube 220 is not limited to be made of silicone. The neck portion 223 is adjacent to the sleeve joint 221. The inner wall of the neck portion 223 is provided with at least one annular convex rib 224. In an embodiment, the inner wall of the neck portion 223 is provided with two annular convex ribs 224 which are spaced apart from each other, but not limited thereto. The size of the caliber of the sleeve joint 221 is gradually enlarged in the direction away from the neck portion 223. The shape of the sleeve joint 221 is similar to a horn. In an embodiment of the present disclosure, the opening of the bottom portion of the elastic tube 222 is surrounded by for grooves 225. In another embodiment, the opening is surrounded by more than three grooves, and not limited to four. The four grooves 225 are arranged in a cross structure, and penetrate radially through the tube wall of the bottom of the elastic tube 222. Therefore, the bottom portion of the elastic tube 222 is divided into four arc-shaped columns by the grooves 225, an inner wall of the arc-shaped column becomes thinner outwardly in the radial direction, and a mismatch 227 is formed between the inner wall of the arc-shaped column 226 and the inner wall of the elastic tube 220.
The tail end of the elongate tube 212 can be separately inserted into the sleeve joint 221 and the neck portion 223. The sleeve joint 221 has a horn shape. The size of the caliber near the opening of the sleeve joint 221 is larger than the caliber near the inside of the neck portion 223, for the tail end of the elongate tube 212 to be inserted into the sleeve joint 221 more easily. In an embodiment, the annular convex ribs 224 of the inner wall of the neck portion 223 can be pressed against the tail end of the elongate tube 212 to increase the friction force between the elastic tube 220 and the elongate tube 210, which effectively reduces the possibility of the tail end of the elongate tube 212 separated from the neck portion 223 and the sleeve joint 221.
Please refer to FIG. 11. The nozzle tube 230 includes a head end 231 and a tail end 232 opposing the head end 231. The size of the caliber of the nozzle tube 230 is gradually reduced from the tail end 232 to the head end 231. An annular flange 233 extends outwardly and radially from the tail end 232. The inner wall of the nozzle tube 230 includes an annular step structure 234. The head end of the elongate tube 211 is inserted into the tail end of the straw 232. The annular step structure is helpful to the position and fastening of the head end of the elongate tube 211.
In use, the straw structure 21 can be assembled in the water bottle, the elastic tube 220 is at the bottom of the bottle body 30, the bottom of the elastic tube 222 is pressed in the bottom the bottle body 30, and the nozzle tube 230 penetrates the convex tube 125 of the second cover 112. The straw structure 21 is longer than the water bottle 1, that is, the length from the opening of the convex tube 125 to the bottom of the bottle body 30. Therefore, the head end 231 of the nozzle tube 230 will push out the opening of the convex tube 125 spontaneously, and the annular flange 233 will be pushed around the convex tube 125 under the second cover 112, such that the head end of the straw 231 can be disposed a fixed length for sucking from the bottle body 30 through the head end of the straw 231. When the convex tube 125 is covered with the first cover 111, the down force of the head end of the straw 231 causes the overall structure of the straw 21 moves down, and the elastic tube 220 will bend limited by the bottom the bottle body 30. When the first cover is opened, the elastic restoring force of the flexible elastic tube 220 causes the over structure of the straw 21 moves up, and the head end of the straw 231 will pop up to the outside of the opening of the convex tube 125 automatically, which facilitates the present disclosure very convenient to use. The cross shaped grooves and the arc-column at the bottom of the elastic tube 222 cause the arc-shaped column 226 to be easily spread out by exerting a slightly downward pressure by user, for a user to suck the liquid at the bottom of the bottle body 30 easily.
Therefore, the straw structure according to the present disclosure can be used in a portable water bottle. When a user opens the cover, the straw structure will automatically bounce up and be reset by the elastic restoring force of the elastic tube. Besides, the horn-shaped opening of the sleeve joint is helpful for inserting the elongate tube into the sleeve joint and the neck portion of the elastic tube. The annular convex rib of the neck portion of the elastic tube helps to fix the elongate tube. The cross-shaped grooves and the arc-shaped column at the bottom of the elastic tube can help to suck the liquid remaining at the bottom of the bottle.
In summary, with the first cover, the second cover, the push button structure and the straw structure according to the present disclosure, when the first buckle member is buckled with the first buckle joint, even if the vibration of the bottle or the outer lateral portion of the bottle being mistakenly contacted, the first buckle member and the first buckle joint are not likely to be separated from each other in an unexpected situation because of the design of the elastic restoring force of the elastic member. Besides, the elastic restoring force is provided by the elastic tube of the straw structure of the water bottle, causes the overall structure of the straw would move up after the first cover is opened, and the head end of the straw would pop up out of the opening of the convex tube spontaneously. The water bottle according to the present disclosure has the effects of convenient to use.
