[0025] See also Figures 1 to 5The self-sealing straw plastic bottle of one embodiment of the present invention comprises a bottle body 10, a bottle cap 20, a straw 30, and a gravity ball 40. In this embodiment, the gravity ball 40 is made of metal. The bottle body 10 and the bottle cap 20 are connected by a rotating shaft at one end and interlocked at the other end. The straw 30 is disposed within the bottle body 10 and comprises a flexible section 31 proximal to the bottle cap 20, a water-absorbing section 33 distal to the bottle cap 20, and an intermediate section 32 connecting the flexible section 31 and the water-absorbing section 33. The intermediate section 32 is connected to the bottle body 10 on the side proximal to the bottle cap 20. A liquid inlet 41 is provided within the gravity ball 40. The free end of the water-absorbing section 33 is connected to the gravity ball 40, and the water-absorbing section 33 is in communication with the liquid inlet 41. A receiving cavity 21 is provided on the sealing surface of the bottle cap 20 and the bottle body 10. The flexible section 31 is bent and accommodated within the receiving cavity 21 when the bottle cap 20 is closed.
[0026] The self-closing straw plastic bottle of the present invention operates as follows: the bottle cap 20 is connected to the bottle body 10 via a hinge at one end and interlocked at the other end, closing the bottle cap. In this state, the flexible section 31 of the straw 30 is bent and accommodated within the accommodating cavity 21 after the cap 20 and the bottle body 10 are closed. The intermediate section 32 is connected to the bottle body 10 near the cap 20. The water-absorbing section 33 is connected to a gravity ball 40. Since the gravity ball 40 is made of metal, it rests at the bottom of the bottle body 10 due to its own weight. When the user opens the cap 20, i.e., undoes the interlocking portion and flips the cap 20 open via the hinge, the flexible section 31 gradually expands as the cap 20 opens. Due to the connection between the intermediate section 32 and the bottle body 10, the flexible section 31 and the intermediate section 32 maintain a certain shape, allowing the straw 30 to be ready for water-absorbing. When the user is finished using the bottle, the cap 20 is replaced on the bottle body 10. At this time, the flexible section 31 will be bent again during the closing process and accommodated in the accommodating cavity 21 after the bottle cap 20 and the bottle body 10 are closed.
[0027] Compared with the prior art, the self-sealing straw plastic bottle of the present invention can store the straw 30 in the accommodating cavity 21 of the bottle cap 20 when not in use, which is in a relatively closed space, avoiding direct contact with the external environment, reducing the possibility of dust, bacteria and other pollutants adhering to the straw 30, and ensuring the cleanliness and hygiene of the straw 30; avoiding the problem of bacterial growth caused by liquid residue; the straw 30 with the gravity ball 40 can ensure that the liquid can be sucked up regardless of the angle of the bottle, without the need to deliberately adjust the posture of the bottle, allowing users to easily drink water in various situations; when the straw 30 is not in use, the straw 30 is in a closed state, and even if the bottle is accidentally knocked over or squeezed, the liquid in the bottle will not leak out of the straw 30.
[0028] Please refer to Figures 3 to 5The bottle body 10 includes a closing section 11 that closes with the bottle cap 20 and a receiving section 12 that is sleeved in the closing section 11; the closing section 11 is connected to the bottle cap 20 at one end and is buckled at the other end; a fixed shaft 13 is provided on the side where the closing section 11 is connected to the bottle cap 20 rotation axis, and a sleeve 22 that cooperates with the fixed shaft 13 is provided on the side where the bottle cap 20 is connected to the closing section 11 rotation axis. When the bottle cap 20 needs to be opened, the user applies an external force to rotate the bottle cap 20 around the fixed shaft 13; the sleeve 22 on one side of the bottle cap 20 rotates on the fixed shaft 13; due to the cooperation between the fixed shaft 13 and the sleeve 22, the bottle cap 20 can be flipped open from the closing section 11 in a stable manner; the opening action of the bottle cap 20 is relatively smooth and the opening angle of the bottle cap 20 can be controlled, which is convenient for the user to operate; when closing the bottle cap 20, the user rotates the bottle cap 20 back around the fixed shaft 13; the sleeve 22 slides along the fixed shaft 13 until the bottle cap 20 is opened. The closing surface of the cap 20 is completely fitted with the closing section 11 of the bottle body 10; the buckling part firmly fixes the bottle cap 20 on the bottle body 10 to keep the bottle in a closed state; the closing section 11 is mainly used to cooperate with the bottle cap 20, and realizes the opening and closing function of the bottle cap 20 by means of a rotating shaft connection and a buckling connection; the fixed shaft 13 provided therein is the center of rotation of the bottle cap 20, providing support for the rotation of the bottle cap 20; at the same time, the structural design of the closing section 11 also takes into account the sealing performance with the bottle cap 20, ensuring that the bottle can effectively prevent liquid leakage when in a closed state.
[0029] The self-sealing straw plastic bottle also includes a first torsion spring 14 arranged on the fixed shaft 13, one end of the first torsion spring 14 is against the bottle cap 20, and the other end is against the closing section 11. When the user applies external force to open the bottle cap 20, the bottle cap 20 rotates around the fixed shaft 13; at this time, the first torsion spring 14 will be twisted and elastically deformed; because one end of the torsion spring is against the bottle cap 20, and the other end is against the closing section 11, it will generate an elastic force that hinders the opening of the bottle cap 20; this can make the bottle cap 20 feel a certain resistance during the opening process, preventing the bottle cap 20 from being easily opened due to an accidental slight touch, thereby improving the stability and controllability of the opening of the bottle cap 20; when the user closes the bottle cap 20, as the bottle cap 20 gradually approaches the closing position, the degree of torsion of the first torsion spring 14 gradually decreases; due to the elastic recovery force of the torsion spring itself, it will generate a force to assist in closing the bottle cap 20; this force can make the bottle cap 20 fit more tightly against the closing section 11 of the bottle body 10 The first torsion spring 14 is in a state of elastic deformation, which continuously applies pressure to the bottle cap 20 and the closing section 11. This pressure helps to maintain a tight connection between the bottle cap 20 and the bottle body 10, preventing the bottle cap 20 from being accidentally opened due to external factors such as vibration and shaking. At the same time, the elastic force of the torsion spring can also play a certain sealing role on the tiny gaps that may exist between the bottle cap 20 and the bottle body 10, further preventing liquid from leaking from these gaps.
[0030] A fixed buckle 23 is provided on the bottle cap 20 on the side facing away from the shaft sleeve 22, and a movable fastener 15 is provided on the closing section 11 on the side facing away from the fixed shaft 13, which cooperates with the fixed buckle 23. The movable fastener 15 includes a connecting shaft 150 provided on the closing section 11, a movable buckle 151 sleeved on the connecting shaft 150 and cooperating with the fixed buckle 23, and a second torsion spring 152 sleeved on the connecting shaft 150 and abutting against the closing section 11. The movable buckle 151 at the top of the connecting shaft 150 is engaged with the fixed buckle 23, and the movable buckle 151 at the bottom of the connecting shaft 150 abuts against the free end of the second torsion spring 152. When the bottle cap 20 is closed onto the bottle body 10, the fixed buckle 23 gradually approaches the movable buckle 151 as the bottle cap 20 rotates; at this time, the movable buckle 151 is in the initial position under the elastic force of the second torsion spring 152; when the fixed buckle 23 contacts the movable buckle 151, the bottle cap 20 continues to press down, which will apply a force to the movable buckle 151; this force causes the movable buckle 151 to rotate around the connecting shaft 150, overcoming the elastic force of the second torsion spring 152. The second torsion spring 152 is provided to hold the movable buckle 151 in place and the second torsion spring 152 is provided to hold the movable buckle 151 in place. After being fastened, a certain pressure can be applied to the fixed buckle 23, thereby enhancing the fastening stability and preventing the fixed buckle 23 from accidentally loosening. When the bottle cap 20 needs to be opened, the user applies an outward pulling force to the bottle cap 20. This pulling force is transmitted to the movable buckle 151 through the fixed buckle 23. Since the direction of the pulling force is opposite to the fastening direction of the movable buckle 151, the movable buckle 151 is subjected to a torque causing it to rotate in the opposite direction around the connecting shaft 150. This torque causes the movable buckle 151 to overcome the elastic force of the second torsion spring 152, and the fastening part of the movable buckle 151 gradually loosens the fixed buckle 23. When the pulling force is large enough, the fixed buckle 23 is completely disengaged from the fastening of the movable buckle 151, and the bottle cap 20 can now be rotated open around the fixed axis 13. During this process, the second torsion spring 152 is further compressed. When the bottle cap 20 is opened, the elastic force of the second torsion spring 152 causes the movable buckle 151 to return to its initial position, waiting for the next fastening operation.
[0031] Please refer to Figure 1 and Figure 4The self-sealing straw plastic bottle also includes an insulating sleeve 50 that fits over the bottle body 10. When a hot drink is inside the bottle, heat transfers from the inside of the bottle body 10 to the outside. The insulating sleeve 50 acts as a barrier, significantly slowing down the heat transfer. Wrapped around the bottle body 10, the insulating sleeve 50 protects the bottle body 10 from physical damage, such as collisions and scratches. For example, during daily use, the bottle may collide with other objects. The insulating sleeve 50 acts as a cushion, absorbing the impact of the collision, protecting the integrity of the bottle body 10, and extending the bottle's service life.
[0032] The thermal insulation sleeve 50 is provided with gripping grooves 51 that fit the fingers. When a user grasps the thermal insulation sleeve 50 with gripping grooves 51, the fingers fit naturally into these grooves. The human hand structure does not form a flat surface when grasping an object, but rather has natural curves and arcs. The shape and position of the gripping grooves 51 are designed based on the shape and gripping habits of human fingers, ensuring a more snug fit between the fingers and the thermal insulation sleeve 50.
[0033] Please refer to Figures 2 to 4 The bottle body 10, opposite the accommodating cavity 21, is provided with an arc-shaped water outlet 60 that converges from all sides toward the center. This characteristic of the arc-shaped water outlet 60 converging from all sides toward the center allows the liquid to flow out in a relatively concentrated stream. When the user drinks, this stream can accurately enter the mouth. It's like an invisible guiding channel, along which the liquid converges and flows into the mouth, reducing the possibility of liquid splashing. For example, when drinking sports drinks or juice, the liquid can enter the mouth more accurately, making it easier for the user to swallow.
[0034] The containing section 12 includes an outer shell 120 disposed on the outside and an inner liner 121 disposed within the outer shell 120; an insulating layer 122 is disposed between the outer shell 120 and the inner liner 121. In this embodiment, the outer shell 120 is made of plastic. When the bottle contains a hot or cold drink, heat will naturally transfer from the high-temperature area to the low-temperature area; in the case of a hot drink, the heat is conducted from the liquid inside the inner liner 121 to the wall of the inner liner 121; in an ordinary bottle without an insulating layer 122, when the temperature of the liquid in the bottle changes, heat convection will occur; heat convection is a method of heat transfer caused by temperature differences within a liquid or gas; however, in this bottle with the inner liner 121 and the outer shell 120 forming the insulating layer 122, the insulating layer 122 between the inner liner 121 and the outer shell 120 can block heat convection.
[0035] The liquid inlet 41 is provided on one side of the gravity ball 40, with the bottom of the gravity ball 40 abutting against the bottom surface of the inner liner 121. When the user sucks on the straw 30, the air pressure inside the straw 30 decreases; at this point, the external atmospheric pressure pushes the liquid inside the bottle into the straw 30. Because the liquid inlet 41 is located on one side of the gravity ball 40, regardless of the tilt angle of the bottle body 10, the bottom of the gravity ball 40 always abuts against the bottom surface of the inner liner 121 under the action of its own gravity. This ensures that the liquid inlet 41 can contact the liquid inside the bottle. Even if there is less liquid in the bottle or the bottle body 10 is tilted, the liquid will gather around the gravity ball 40 under the action of gravity and enter the straw 30 through the liquid inlet 41. For example, when the bottle body 10 is almost flat, the liquid will spread out on the bottom of the bottle under the action of gravity, and the gravity ball 40 will "lie" on the liquid by its own weight, allowing the liquid inlet 41 to be immersed in the liquid, thereby achieving liquid inhalation.
[0036] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
