Description

Technical Field

[0001] This invention relates to the field of water cup technology, and in particular to a spring-loaded spout cap and a water cup. Background Technology

[0002] Existing water bottles with spouts, such as children's water bottles and sports water bottles, generally suffer from the following technical problems:

[0003] First, the spouts are mostly exposed or require manual insertion and removal for storage, making them prone to dust and bacterial growth after use, and the manual operation is cumbersome. Second, they have poor leak-proof performance; when the lid is closed, the seal between the spout and the cup mouth relies on static structures such as soft rubber stoppers, and long-term opening and closing can easily lead to seal failure, resulting in a high risk of liquid leakage. In addition, the spout popping out / retracting requires additional manual operation, which does not meet the convenience requirement of "one-click use" and results in a poor user experience. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an elastic spout cap and a water cup that combines good sealing and leak prevention with convenient operation. The spout automatically pops out and retracts through the linkage of the flip cap and spring, solving the problems of cumbersome spout storage, insufficient leak prevention, and poor ease of use in existing water cups with spouts.

[0005] A spring-loaded spout cap, applied to a cup body, includes a drinking assembly, a flip-top, a cup rim sealing panel, a flip-top mounting base, a spout channel component, and a support bracket; wherein:

[0006] The drinking assembly includes a mouthpiece and a straw that are connected to each other; the mouthpiece has a first protrusion on its outer side, and a limiting member is sleeved around the straw, with a spring and a water-sealing ring sleeved on the limiting member;

[0007] The mouthpiece channel has an open inner cavity for accommodating the drinking assembly;

[0008] The cup-mouth sealing panel is provided with a first opening and a second opening; the first opening is used to expose the mouthpiece; a lever is provided on the inner side of the cup-mouth sealing panel, one end of the lever is connected to the cup-mouth sealing panel through a rotating shaft, and the other end serves as a movable end for abutting against the first protrusion and can rotate relative to the cup-mouth sealing panel.

[0009] One end of the flip cover is connected to the cup mouth sealing panel via a pivot, and the other end is a movable end that moves relative to the cup mouth sealing panel to form an open state and a closed state; the inner side of the flip cover is provided with a second protrusion that can pass through the second opening;

[0010] The flip-top assembly is a hollow structure with openings at the top and bottom. The cup rim sealing panel is located above it, and the support bracket is located below it. The support bracket has an opening that exposes the bottom of the drinking assembly or the bottom of the spout channel. The cup rim sealing panel, the flip-top assembly, and the support bracket are integrated to form an accommodating space for accommodating the spout channel. The flip-top assembly is detachably connected to the cup body.

[0011] When the flip cover is closed, the second protrusion passes through the second opening and presses the lever. The lever presses the first protrusion and compresses the spring, causing the mouthpiece and the straw to retract into the cup body below the cup mouth sealing panel, and causing the water sealing ring to block the gap between the mouthpiece channel and the straw.

[0012] When the flip cover is opened, the spring returns to its original position, driving the lever to release the pressure on the first protrusion, causing the straw and the mouthpiece to move outwards from the cup body until the mouthpiece is exposed above the sealing panel of the cup mouth, and the water sealing ring moves synchronously to form an exhaust channel between the mouthpiece channel and the straw.

[0013] A water cup includes a spring-loaded spout cap as described above, and a cup body that matches the spring-loaded spout cap.

[0014] The elastic spout cap and water cup provided by this invention have the following advantages compared with the prior art:

[0015] 1) Automated operation: Through the linkage design of flip-top opening and closing and spring force, the nozzle can be "popped out with one click and automatically stored", eliminating the need for manual insertion and removal, thus improving the user experience.

[0016] 2) Sealing and heat preservation: The integrated structure formed by the cup mouth sealing panel, flip-top mounting base, support bracket and suction channel can achieve both liquid sealing and heat preservation effects.

[0017] 3) Hygiene protection: The spout is normally stored under the sealing panel at the mouth of the cup to avoid exposure and contamination, reducing the risk of bacterial growth; at the same time, all components inside the lid are made of food-grade materials to ensure hygiene and safety.

[0018] 4) Structural reliability and replaceability: The cup-mouth sealing panel, flip-top assembly, suction nozzle channel and support bracket in the lid are ultrasonically integrated, ensuring the connection strength of the components; at the same time, the suction component and flip-top are detachable parts, which facilitates the replacement of the whole or part.

[0019] 5) Adaptability and flexibility: The detachable assembly structure supports modular combination of the cup body and the spout cap, making cleaning and maintenance convenient. Attached Figure Description

[0041] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0042] Provides a flexible spout cap and a water cup, such as Figures 1 to 10 As shown, the elastic spout cover includes: a drinking assembly 60, a flip-top 10, a cup-mouth sealing panel 20, a flip-top mounting base 30, a spout channel component 40, and a support bracket 50. Wherein:

[0043] The drinking assembly includes a mouthpiece 61 and a straw 62 that are interconnected; the straw is supported by a flexible material and can be slightly bent to extend into the cup body; a limiting member 63 is fitted around the straw, which covers the straw and is used to assemble a spring 64 and a sealing ring 66. The limiting member can be a separate structural component or it can be integrally formed with the mouthpiece or straw.

[0044] The outer side of the nozzle is provided with a first protrusion 611, which can be integrally formed with the nozzle or provided by a separate part fitted onto the nozzle.

[0045] The spout channel is used to provide an open cavity for accommodating the drinking assembly, and its specific shape can be flexibly set, for example, to match the size of the cup opening.

[0046] The cup mouth sealing panel is provided with a first opening 201 and a second opening 202; the first opening is used to expose the mouthpiece; the inner side of the cup mouth sealing panel is provided with a lever 70, one end of the lever is connected to the cup mouth sealing panel through a rotating shaft, and the other end is used as a movable end to abut against the first protrusion and can rotate relative to the cup mouth sealing panel.

[0047] One end of the flip cover is connected to the cup mouth sealing panel via a pivot, and the other end is a movable end that moves relative to the cup mouth sealing panel to form an open state and a closed state; the inside of the flip cover is provided with a second protrusion 101 that can pass through the second opening;

[0048] The flip-top assembly is a hollow structure with openings at the top and bottom. A cup-mouth sealing panel is set on the top, and a support bracket is set on the bottom. The support bracket has an opening 501 that exposes the bottom of the drinking component or the bottom of the mouthpiece channel. The cup-mouth sealing panel, the flip-top assembly, and the support bracket are connected as a whole to form an accommodating space for accommodating the mouthpiece channel. The flip-top assembly is assembled and fixed to the cup body by a detachable connection method such as thread 301 or thread 81.

[0049] When the flip cover is closed, the second protrusion passes through the second opening and squeezes the lever. The lever presses down on the first protrusion and compresses the spring, causing the mouthpiece and straw to retract into the cup body to below the cup mouth sealing panel, and causing the water sealing ring to block the gap between the mouthpiece channel and the straw.

[0050] When the flip cover is opened, the spring returns to its original position, and the drive lever releases the pressure on the first protrusion, causing the straw and mouthpiece to move outwards from the cup body until the mouthpiece is exposed above the sealing panel at the cup mouth. Simultaneously, the water sealing ring moves to create an exhaust channel between the mouthpiece channel and the straw.

[0051] The sealing ring is used to block the gap between the spout and the straw when the lid is closed, thus preventing leakage. At the same time, when the lid is opened, the sealing ring moves synchronously to form an exhaust channel, which can balance the air pressure inside and outside the cup, making it easier for the liquid inside the cup to be sucked out.

[0052] Furthermore, a latch 102 is provided on the movable end of the flip cover, and a slot 203 is provided on the cup mouth sealing panel to engage with the latch to achieve a closed state. The specific shape or position of the latch and the slot can be flexibly set, as long as it can achieve the flip cover closing relative to the cup mouth sealing panel.

[0053] Furthermore, a water-sealing adhesive fastener 103 is provided on the inner side of the flip cover. When the flip cover is closed, the water-sealing adhesive fastener is used to seal the upper end of the nozzle, blocking the outlet of the nozzle and preventing the liquid in the cup from flowing out of the nozzle.

[0054] Furthermore, an insulating filler 401, such as foam material, is provided between the spout channel and the accommodating space. The insulating filler can increase the heat insulation and heat preservation effect of the entire cup lid.

[0055] Furthermore, the suction nozzle channel is made of sealing and heat-insulating material to give the entire cover good sealing and heat-insulating performance.

[0056] Furthermore, the rotation direction of the lever is consistent with the rotation direction of the flip cover. That is, the rotation direction of the lever is consistent with the direction of rotation when the flip cover is opened or closed, so as to form a synchronous linkage between the two, so that when the flip cover is opened, the suction nozzle can extend synchronously, and when the flip cover is closed, the suction nozzle can retract synchronously.

[0057] Furthermore, it also includes a drinking component travel limiter 67 fitted over the straw, the diameter of which is larger than the diameter of the opening. During the opening of the lid, the mouthpiece and straw move outwards from the cup body until the drinking component travel limiter abuts against the opening of the support bracket. The drinking component travel limiter can control the range of motion of the mouthpiece and straw to prevent them from popping out excessively.

[0058] Furthermore, a limiting step 631 is provided on the limiting member; when the spring is sleeved on the limiting member, the upper end of the spring abuts against the suction nozzle, and the lower end of the spring abuts against the limiting step. Since the limiting member covers the suction tube, the limiting step on it helps ensure the stability of the suction nozzle relative to the suction tube during movement. It can be understood that the limiting step is not limited to being provided on the limiting member, but can also be provided within the suction nozzle channel.

[0059] Furthermore, it also includes a nozzle pressing bracket 65, which is an independent component relative to the nozzle for easy cleaning and disassembly. It is fitted onto the nozzle and forms an integral part with it. The nozzle pressing bracket is provided with a first protrusion 611. When the first protrusion is pressed against by the lever, the nozzle pressing bracket and the nozzle move down and retract together.

[0060] Furthermore, the cup-mouth sealing panel, flip-top mounting base, suction nozzle channel component, and support bracket are ultrasonically integrally molded, resulting in better structural tightness and facilitating overall replacement during disassembly and maintenance.

[0061] Furthermore, a third protrusion 701 is provided on the upper surface of the lever; when the flip cover rotates, the second protrusion passes through the second opening and abuts against the third protrusion, thereby squeezing the lever. The abutment of the second and third protrusions forms a lever fulcrum, making the rotation of the lever more advantageous.

[0062] Furthermore, when the flip-top mounting base is assembled and fixed to the cup body, a sealing ring 90 is placed between the support bracket and the inner side of the cup mouth to enhance the sealing and waterproof performance between the lid and the cup body.

[0063] A water cup is provided, comprising a spring-loaded spout cap as described above, and a cup body 80 that matches the spring-loaded spout cap. The specific shape of the cup body is not specifically limited.

[0064] The above is a description of the present invention to help understand it. However, the implementation of the present invention is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of the present invention should be considered equivalent substitutions and are included within the protection scope of the present invention.
