Description

Technical Field

[0001] This utility model relates to a water bottle, specifically a splash-proof drinking cup. Background Technology

[0002] Existing drinking bottle designs, especially those for infant feeding, commonly suffer from a critical technical flaw. When filled with hot liquid, the liquid expands upon heating, generating a large amount of gas and causing a rapid increase in internal pressure. Due to deficiencies in the connection between the vent valve and the nipple in traditional designs, high-pressure gas pushes the liquid backflow through the vent channel into the nipple cavity. As the nipple cavity gradually fills with liquid, the sustained high pressure causes the liquid to violently spray out of the nipple hole when external pressure changes, such as when the dust cap is opened, resulting in the typical milk spraying phenomenon. This spray not only easily causes serious safety accidents such as facial burns and choking on the infant's airway, but also increases the difficulty of care due to the sudden liquid ejection. Furthermore, during daily use, such as shaking the bottle to mix the contents or moving it, the liquid inside may fluctuate violently due to vibration, potentially triggering accidental spraying, resulting in staining of the user's clothing, environmental contamination, and a degraded user experience. These problems stem from the lack of effective pressure buffering mechanisms and sealing controls in existing drinking bottles, preventing the safe release or prevention of internal high pressure, which negatively impacts the long-term safety and reliability of the product.

[0003] CN217793835U discloses a splash-proof duckbill water bottle, comprising a duckbill-shaped nipple and a water bottle, which are detachably connected. Two arc-shaped diaphragms are symmetrically arranged inside the mouth of the duckbill-shaped nipple, and the cross-section of the two arc-shaped diaphragms in the height direction forms a V-shape to close the mouth. Each arc-shaped diaphragm includes an arc-shaped edge and a straight edge. The arc-shaped edge is connected to half of the annular inner wall of the mouth, and the lower ends of the two straight edges are provided with reinforcing ribs, with slits for liquid guidance on the reinforcing ribs. This invention utilizes two combined V-shaped arc-shaped diaphragms to close the mouth of the duckbill-shaped nipple. Furthermore, the reinforcing ribs exert a certain gravitational pressure on the slits, allowing backflow, so that the liquid is drawn out under suction, avoiding fluid waste and hot water spray causing scalding or wetting of the user, thus ensuring the user's safety. However, this splash-proof water bottle has a relatively complex structure and high production cost. Therefore, we propose a splash-proof water bottle with a simpler structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a splash-proof drinking cup.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A spill-proof sippy cup includes a bottle body and a cap mounted on the bottle body. A dust cover is hinged to the cap. The cap has a drinking spout with a drinking spout that communicates with the interior of the bottle body. The drinking spout has a push button and at least one one-way valve. The push button is located on one side of the one-way valve. When the drinking spout is not subjected to external pressure, the one-way valve is closed. When force is applied to the push button, the one-way valve opens. The dust cover has a through hole into which the push button extends. When the dust cover is closed, there is a gap between it and the cap.

[0007] As a further improvement, the push button, one-way valve and drinking spout are integrally molded.

[0008] As a further improvement, the pressing button protrudes from the surface of the drinking spout, and after the pressing button extends into the through hole of the dust cover, the upper surface of the pressing button is flush with the opening of the through hole, or the pressing button protrudes from the through hole.

[0009] As a further improvement, the one-way valve is V-shaped.

[0010] As a further improvement, the bottle is equipped with a straw, which is connected to a drinking spout.

[0011] As a further improvement, the bottle cap is provided with a handle that bends toward one side of the bottle.

[0012] As a further improvement, the drinking spout and bottle cap are either threaded or snap-fit.

[0013] As a further improvement, the bottle cap has a notch and a recessed groove. When the dust cap is closed, one side is locked in the notch position, and a gap is formed between the dust cap and the recessed groove.

[0014] This utility model has the following beneficial technical effects:

[0015] The drinking spout can be opened and closed in a controlled manner by using a one-way valve and a push button. The gap design between the dust cover and the bottle cap prevents liquid spraying caused by sudden changes in external pressure, effectively solving the milk spraying phenomenon mentioned in the background technology. The bottle can be depressurized and vented without opening the cap, which has the advantages of significantly improving safety and preventing scalding or choking caused by accidental spraying of high-temperature liquid.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] like Figure 1-2 As shown, a spill-proof sippy cup includes a bottle body 1 and a cap 2 mounted on the bottle body 1. A dust cover 3 is hinged to the cap 2. The cap 2 has a drinking spout 4 with a drinking nozzle 5, which communicates with the interior of the bottle body 1. The drinking spout 4 has at least one-way valve 6 and a push button 7. The push button 7 is located on one side of the one-way valve 6. When the push button 7 is not subjected to external pressure, the one-way valve 6 is closed. When force is applied to the push button 7, the one-way valve 6 opens. The dust cover 2 has a through hole into which the push button 7 extends. When the dust cover is closed, there is a gap between it and the cap, allowing hot steam inside the bottle to escape through the gap. This allows for depressurization of the bottle without opening the cap, improving safety. After depressurization and steam release, opening the dust cover ensures that the pressure inside and outside the bottle is consistent, preventing milk spraying and further enhancing safety.

[0023] In actual use of the drinking bottle, when the bottle body generates high pressure due to the expansion of the liquid at high temperature or vibration, the one-way valve on the drinking spout is kept closed without external pressure. With the dust cover closed, the drinking spout on the drinking spout is sealed, thus effectively blocking the path of the liquid inside the bottle from being sprayed out through the drinking spout.

[0024] Furthermore, the push button 7 on the drinking spout 4 is located on the side of the one-way valve 6. When an external force is applied to the push button, the one-way valve is opened, forming a controllable venting channel. In the non-use state, the automatic closing mechanism of the one-way valve forms a reliable seal, which can also prevent external dust from entering the bottle through the one-way valve 6 when the dust cover is open.

[0025] The bottle body 1 can be made of glass or food-grade silicone, and the cap is made of polypropylene. The dust cover is hinged to the cap via a plastic hinge. The drinking spout is made entirely of food-grade silicone, with a one-way valve being a silicone elastic diaphragm structure. The push button is a raised part on the surface of the drinking spout. The dust cover has a circular through hole into which the push button extends. When the dust cover is closed, there is an operating gap between it and the cap. This gap ensures that a finger can apply force to the push button through the through hole without affecting the dustproof function.

[0026] In practical applications, some embodiments of this application propose a structure of a push button 7, a one-way valve 6, and a drinking spout 4. However, in the implementation process, since the components are assembled separately, there are small gaps at the interfaces. When the liquid inside the bottle is hot or under high pressure due to shaking, the liquid can easily seep out through the gaps, causing the one-way valve to fail to seal and resulting in milk spraying, which poses a safety hazard of scalding or choking on the user.

[0027] Specifically, the solution of this application integrates the push button, one-way valve, and drinking spout into a single molded structure, creating a continuous, gapless sealing path inside the drinking spout. When the liquid inside the bottle expands due to high temperature or generates high pressure due to violent shaking, the liquid cannot leak out from the component connection, thus effectively maintaining the closed state of the one-way valve. At the same time, this structure enhances the overall rigidity and stability of the drinking spout. Under external pressing pressure, the push button can reliably drive the one-way valve to open and close, avoiding sealing failure caused by local deformation. Furthermore, in conjunction with the V-shaped design of the bottle cap, dust cap, and one-way valve, it ensures that when the dust cap is closed, the one-way valve only opens during the pressing operation, allowing the air pressure inside the bottle to be quickly discharged outside, thereby achieving uniform air pressure inside and outside the bottle and significantly reducing the risk of unexpected liquid spraying.

[0028] In addition, the push button 7 protrudes from the surface of the drinking spout 4 for easy pressing. The push button protruding from the drinking spout surface means that the push button portion extends beyond the outer surface of the drinking spout; this can be achieved through a slightly raised or noticeably raised design, with the aim of making it easy for the user to identify and apply pressure.

[0029] The push button can be designed as a hemispherical protrusion, and the dust cover's through-hole is a circular opening. When the dust cover is closed, the push button extends into the through-hole of the dust cover, allowing the push button to be pressed down to release steam and pressure without opening the dust cover.

[0030] The one-way valve 6 is V-shaped and can be integrally formed inside the drinking spout through injection molding, which aims to ensure structural stability and simplify the assembly process.

[0031] The bottle body 1 is equipped with a straw 8, which is connected to the drinking spout 4, making it suitable for use by different infants and young children.

[0032] In addition, the bottle cap 2 is equipped with a handle 9, which is bent toward the side of the bottle body 1 to fit the usage habits of infants and young children.

[0033] The drinking spout and bottle cap are either threaded or snap-fit.

[0034] Among them, the threaded installation structure refers to the structure that achieves connection through a helical pair, which can be achieved by using external threads and internal threads. Its purpose is to provide adjustable fastening force and self-locking characteristics to ensure a stable connection. The snap-fit ​​installation structure refers to the structure that achieves quick locking through elastic deformation, which can be achieved by using protrusions and grooves. Its purpose is to provide convenient installation and disassembly while maintaining the reliability of the connection.

[0035] The drinking spout can be flexibly replaced according to usage habits.

[0036] In addition, the bottle cap 2 is provided with a notch 10 and a recessed groove 11. When the dust cover 3 is closed, one side is stuck in the notch 10 position, and a gap is formed between the dust cover and the recessed groove. Without opening the dust cover, after pressing the button, the hot steam discharged from the one-way valve can be discharged outward through the recessed groove 11 and the notch 10.

[0037] It should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
