For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0023] Please refer to Figures 1 to 3 For the plastic bottle for preventing overflow of an embodiment of the utility model, including bottle body 10, bottle cap 20, spout 30, kettle cover 40 and kettle plug 50, bottle body 10 sets up first inner thread 11, bottle cap 20 is provided with connecting column 21, connecting column 21 is provided with the first outer thread 210 matched with the first inner thread 11, connecting column 21 is provided with vertical through hole 22, the bottle cap 20 on the side of bottle body 10 is provided with mounting groove 23, spout 30 includes the water outlet pipe 31 provided in through hole 22 and the limiting boss 32 installed on the mounting groove 23 and matched with the water outlet pipe 31 outside, kettle cover 40 includes the first flexible section 41 provided on one side of bottle cap 20 and the cover section 42 connected with the free end of first flexible section 41, cover section 42 is matched with the upper surface of bottle cap 20, kettle plug 50 includes the second flexible section 51 provided on the upper surface of bottle cap 20 and the water stop plug 52 connected with the free end of second flexible section 51 and matched with water outlet pipe 31. In the embodiment, bottle body 10 is plastic material.
[0024] The working principle of the plastic bottle for preventing spilling and leaking is as follows: the first inner thread 11 and the first outer thread 210 are matched to realize the close connection of the bottle cap 20 and the bottle body 10; the first flexible section 41 is connected to one side of the bottle cap 20, so that the closing section 42 can move relatively flexibly; the closing section 42 is matched with the upper surface of the bottle cap 20, when the kettle cover 40 is in the closing state, the closing section 42 can be closely attached to the bottle cap 20, further preventing liquid from spilling; when the kettle spout 30 is not used to pour liquid or the bottle body is shaken, etc., the closing section 42 of the kettle cover 40 can effectively block the liquid from spilling out of the kettle spout 30; when the liquid is not needed to be poured out, the water stop plug 52 can be inserted into the water outlet pipe 31 of the kettle spout 30; the second flexible section 51 can provide a certain elastic deformation, so that the water stop plug 52 can tightly block the water outlet pipe 31; preventing the liquid from flowing out of the kettle spout 30 when the bottle body is inclined or shaken.
[0025] Compared with the prior art, the plastic bottle for preventing spilling and leaking, the water stop plug 52 of the kettle plug 50 is closely matched with the kettle spout 30, when the bottle body 10 is shaken or inclined, the water stop plug 52 blocks the water outlet pipe 31 under the elastic action of the second flexible section 51, avoiding the liquid from flowing out; because the closing section 42 is matched with the upper surface of the bottle cap 20, when the closing section 42 needs to be closed with the bottle cap 20, the first flexible section 41 is bent to make the closing section 42 close to the bottle cap 20, further preventing the liquid from spilling; when the liquid needs to be poured out, the liquid flows to the water outlet pipe 31 of the kettle spout 30 from the inside of the bottle body 10 through the through hole 22 of the bottle cap 20 connecting column 21 under the action of gravity; the design of the kettle spout 30 makes the liquid flow out in a predetermined direction, which is convenient for the user to control the flow amount and flow direction of the liquid.
[0026] Please refer to Figure 1 and Figure 3 The plastic bottle for preventing spilling and leaking also comprises a heat insulation sleeve 60 sleeved outside the bottle body 10. When cold drinks are contained in the bottle, the heat outside wants to enter the bottle to warm the drinks, and the heat insulation sleeve 60 can prevent the rapid transmission of heat; if the outside temperature is high, the heat will gather on the outer layer of the heat insulation sleeve 60, and then only a small amount of heat can slowly enter the bottle through the heat insulation sleeve 60; similarly, when hot drinks are contained in the bottle, the heat insulation sleeve 60 can also prevent the heat in the bottle from being rapidly lost to the outside.
[0027] The plastic bottle for preventing spilling also comprises a slide rail 61 arranged around the circumference of the heat insulation sleeve 60 and a mounting rack 70 slidably arranged on the slide rail 61. The slide rail 61 is arranged along the circumference of the heat insulation sleeve 60 to provide a sliding track for the mounting rack 70. The mounting rack 70 is slidably arranged on the slide rail 61 and can smoothly move along the circumference. The slide rail 61 plays a guiding and limiting role for the mounting rack 70. Since the mounting rack 70 can slide along the circumference, the user can slide the accessory to a suitable position for use after the accessory is installed. For example, the cup can be slid to the back of the bottle when not in use, without affecting the normal holding and use of the bottle. When the cup is needed, it can be slid to a position for conveniently pouring liquid.
[0028] The mounting rack 70 is hollow in the direction of the bottle body 10. The mounting rack 70 can be highly adapted to the shape of the bottle body 10 and tightly attached to the outside of the bottle body 10, which helps to improve the stability of the mounting rack 70 on the bottle body 10 and enables the mounting rack 70 to firmly adhere to the bottle body 10 without shaking or moving when the bottle is moved, held or placed in different positions.
[0029] Please refer to Figure 2 and Figure 3 The plastic bottle for preventing spilling also comprises a sealing ring 80 arranged on the joint surface of the bottle cap 20 and the bottle body 10. The sealing ring 80 can more tightly adhere to the joint surface of the bottle body 10 and the bottle cap 20 under the action of pressure, like a solid defense line, to firmly seal the liquid in the bottle. Even if the liquid in the bottle is in a dynamic state, such as shaking during transportation, the sealing ring 80 can adapt to the pressure change through its elasticity to continuously ensure the sealing effect. The sealing ring 80 can also effectively prevent the liquid from leaking from the joint between the bottle cap 20 and the bottle body 10.
[0030] A positioning rack is arranged on the inner wall of the connecting column 21, a limiting groove is arranged on the positioning rack, and a fixing boss matched with the limiting groove is arranged on the water outlet pipe 31 close to the bottle body 10. When the spout 30 is installed, the water outlet pipe 31 is inserted into the through hole 22 of the connecting column 21. During this process, the fixing boss close to the bottle body 10 moves along the positioning rack on the inner wall of the connecting column 21. When the fixing boss reaches the position of the limiting groove, the fixing boss is clamped into the limiting groove through a certain operation (such as rotating the water outlet pipe 31). The positioning rack provides a guiding path for the fixing boss to ensure that the fixing boss can accurately reach the position of the limiting groove. The cooperation of the limiting groove and the fixing boss enables the spout 30 to be accurately positioned in the connecting column 21 of the bottle cap 20, thereby ensuring that the position of the water outlet pipe 31 of the spout 30 is correct and facilitating the smooth flow of liquid from the bottle through the water outlet pipe 31. Once the fixing boss is clamped into the limiting groove, it can prevent the spout 30 from falling off the connecting column 21. The cooperation of the limiting groove and the fixing boss can withstand a certain external force to maintain the stability of the spout 30 in the connecting column 21.
[0031] Please refer to Figure 2 , including the positioning column 240 set on the inner wall of the connecting column 21 and the water distribution piece 241 set at the bottom of the positioning column 240, the water distribution piece 241 is opposite to the end of the water outlet pipe 31. When the liquid flows from the inside of the bottle body 10 to the spout 30, due to the existence of the positioning column 240, the flow path of the liquid inside the connecting column 21 will be guided to a certain extent; the positioning column 240 guides the liquid to the area where the water distribution piece 241 is located; the water distribution piece 241 is opposite to the end of the water outlet pipe 31, and its main function is to reasonably distribute the liquid; after the liquid is distributed by the water distribution piece 241, it enters the water outlet pipe 31 in a more moderate manner; if there is no water distribution piece 241, the liquid directly impacts the end of the water outlet pipe 31, which may generate a large impact force, especially in the case of fast pouring or high liquid pressure in the bottle; such impact force may cause the liquid to splash, and even may cause the liquid to flow back from the spout 30 to the connecting column 21; the structure improves the anti-overflow performance of the bottle as a whole by making the liquid flow uniformly and moderately into the water outlet pipe 31.
[0032] The second external thread is arranged on the water outlet pipe 31 at the bottom of the limiting boss 32, and the second internal thread is arranged on the through hole 22 of the connecting column 21 and matched with the second external thread; the water outlet pipe 31 is screwed with the through hole 22. When the spout 30 is installed, the second external thread at the bottom of the water outlet pipe 31 is matched with the second internal thread on the through hole 22 of the connecting column 21; by rotating the water outlet pipe 31, the second external thread gradually screws into the second internal thread, and the threaded connection not only plays a tightening role, but also enhances the sealing effect; when the second external thread and the second internal thread are tightly engaged, the small gap between them will be squeezed to be smaller.
[0033] Please refer to Figure 1 and Figure 3 , a plurality of convex strips 25 are arranged on the outer wall of the bottle cap 20. In the process of opening or tightening the bottle cap 20, the friction force can prevent the hand from slipping on the bottle cap 20; the convex strips 25 can make the hand better grasp the bottle cap 20, so that the user can more stably apply torque to open or close the bottle cap 20, especially in the case that the hand is wet or there is a small amount of liquid on the surface of the bottle cap 20, the anti-slip effect is more obvious.
[0034] Please refer to Figure 2 and Figure 3The water stop plug 52 comprises a limiting portion 520 connected with the second flexible section 51 and a sealing portion 521 connected with the free end of the limiting portion 520, the outer diameter of the sealing portion 521 is equal to the inner diameter of the water outlet pipe 31, and the outer diameter of the limiting portion 520 is larger than the outer diameter of the sealing portion 521. When the water stop plug 52 is inserted into the water outlet pipe 31, the sealing portion 521 plays a major role in preventing leakage; since the outer diameter of the sealing portion 521 is equal to the inner diameter of the water outlet pipe 31, it can be closely fitted on the inner wall of the water outlet pipe 31; when it is needed to pour out liquid by using the spout 30, the user can easily pull out the water stop plug 52 by holding the limiting portion 520; since the size of the limiting portion 520 is larger, it is convenient to hold by fingers, and its position is close to the port of the water outlet pipe 31, so it is easy to be touched; after use, it is also very simple to insert the water stop plug 52 back into the water outlet pipe 31, as long as the sealing portion 521 is aligned with the port of the water outlet pipe 31 and is inserted until the limiting portion 520 is clamped; this convenient operation mode enables the user to quickly realize the insertion and pulling out of the water stop plug 52, effectively controls the outflow of liquid and prevents leakage.
[0035] The above only expresses the preferred technical solutions of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the application patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
