Description

Technical Field

[0001] This disclosure relates to the field of daily necessities technology, and in particular to a straw assembly and a drinking bottle. Background Technology

[0002] As infants and toddlers grow, sippy cups or bottles with straws become important tools to help them transition from bottle feeding to independent drinking. To improve ease of use and accommodate the active nature of infants and toddlers, straw designs in the feeding product market are constantly evolving.

[0003] As an important accessory for drinking bottles, straws are especially suitable for helping infants and toddlers in the transitional stage learn to drink independently. Early straws had a relatively simple structure, usually consisting of a tube of uniform diameter.

[0004] During feeding, the temperature of the liquid inside the bottle (such as warm milk) is usually higher than the temperature of the air inside the bottle and the outside environment. This temperature difference may cause the air inside the bottle to expand due to heat, thereby putting pressure on the liquid surface and causing the liquid inside the bottle to spray out.

[0055] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are to be considered exemplary in nature and not restrictive.

[0056] Example 1

[0057] This embodiment provides a straw assembly designed to solve the problem that existing straws are prone to splashing and choking users when the liquid inside the bottle is at a high temperature.

[0058] Figure 1 A cross-sectional schematic diagram of a straw assembly according to an embodiment of the present disclosure is shown. Figure 1 As shown, the straw assembly includes:

[0059] Hollow tube 100 includes a first section 110 and a second section 120. The inner cavity 111 formed by the first section 110 is connected to the tube cavity 121 formed by the second section 120. The top of the first section 110 has a connecting part 130 for connecting with a suction assembly.

[0060] The diameter of the inner cavity 111 is larger than the diameter of the tube 121; the first section 110 and the second section 120 are integrally formed.

[0061] In this embodiment, the hollow tube 100 can be made of silicone material and includes a first section 110 and a second section 120. Specifically, if the first section 110 and the second section 120 are made of the same material and have the same hardness, they are formed into an integral structure through a single injection molding process. This process eliminates any physical seams between the two sections, fundamentally eliminating the possibility of dirt accumulation, making it easy to clean, and ensuring hygiene during use.

[0062] The first section 110 is located at the upper part of the hollow tube 100, and the top of the first section 110 has a connecting part 130 for connecting to a sucking component (such as a nipple). The second section 120 is located at the lower part of the hollow tube 100, and the bottom of the second section 120 is provided with a gravity ball 200 to ensure that the end of the second section 120 can be immersed in liquid at any holding angle.

[0063] The first section 110 forms an inner cavity 111, and the second section 120 forms a tube 121, with the inner cavity 111 and the tube 121 communicating with each other. The diameter of the inner cavity 111 is larger than the diameter of the tube 121 (for example, the diameter of the inner cavity 111 is 6 mm, and the diameter of the tube 121 is 3 mm).

[0064] According to the embodiment of this disclosure, when the liquid inside the bottle is heated and the air expands, propelling the liquid upwards along the straw, the liquid first enters the smaller diameter cavity 121, and then enters the larger inner cavity 111. The spacious inner cavity 111 acts as a buffer chamber, effectively accommodating and slowing down the speed and pressure of the upward-flowing liquid, greatly reducing the risk of liquid spraying out from the end of the suction component (such as the liquid outlet for the user to suck), thereby achieving excellent anti-splash and anti-choking effects.

[0065] In this embodiment, the bottom of the first segment 110 has a transition segment 140 that communicates with the second segment 120. The transition segment 140 can be understood as a part of the first segment 110, and the transition segment 140 has a smooth arc-shaped inner wall, that is, the bottom of the inner cavity 111 gradually narrows, so that the inner wall of the inner cavity 111 smoothly transitions to the lumen 121. In one possible implementation, the transition segment 140 has a smooth conical inner wall. The connection from the opening at the top of the connecting portion 130 through the inner cavity 111, the transition segment 140, the lumen 121 to the opening at the bottom of the gravity ball 200 is continuous and smooth.

[0066] According to the embodiments of this disclosure, this smooth transition design avoids right angles or stepped structures, which can effectively reduce turbulence during liquid flow, prevent air bubble accumulation, and guide the liquid to flow back more smoothly in the non-sucking state, thereby reducing liquid residue in the straw and avoiding waste.

[0067] To achieve connection with the suction component, in this embodiment, the hollow tube 100 and the connecting portion 130 are integrally formed, and the first section 110 and the connecting portion 130 are made of the same material. Figure 2As shown, the specific connection structure is as follows: the upper and lower parts of the connecting portion 130 respectively have a first annular protrusion 131 and a second annular protrusion 133 extending radially outward. An annular groove 132 is naturally formed between the first annular protrusion 131 and the second annular protrusion 133. Correspondingly, the connection structure at the bottom of the suction assembly can be precisely embedded in the annular groove 132 to form a tight and detachable connection.

[0068] According to the embodiments of this disclosure, this connection method is simple and reliable, ensuring the sealing of the connection to prevent leakage, and facilitating user disassembly and installation, as well as cleaning the straw assembly and the suction assembly.

[0069] In a specific scenario disclosed herein, integral molding refers to the process by which the first segment 110 (including the transition segment 140) and the second segment 120 are manufactured into a single, seamless component through a single injection molding process. The injection molding process can use materials of the same grade and hardness, such as liquid silicone. Alternatively, the first segment 110 and the second segment 120 can also be manufactured using the same material with different hardnesses through an integral molding process, thereby obtaining an integrally molded hollow tube 100.

[0070] Example 2

[0071] This embodiment provides a straw assembly that optimizes the specific size, structure, and connection method based on Embodiment 1 to achieve stronger performance.

[0072] The overall structure of the straw assembly is similar to that of Embodiment 1, also including a hollow tube 100 integrally formed from a first section 110 and a second section 120, and a gravity ball 200.

[0073] In this embodiment, the dimensions of each part are given as examples. For example, the overall length of the hollow tube 100 is 160mm, the length of the first section 110 is 40mm, and the length of the first section 110 accounts for 25% of the overall length of the hollow tube 100.

[0074] In one possible implementation, the length of the first section 110 is not less than 20% of the overall length of the hollow tube 100. This ensures that the first section 110 has sufficient length to form a buffer chamber with a considerable volume, thereby more reliably dealing with liquid surges caused by drastic temperature changes or shaking, and providing better anti-splashing effect.

[0075] For example, the diameter of the lumen 121 in the second section 120 is 3 mm, while the diameter of the inner lumen 111 in the first section 110 is 7 mm. The diameter of the inner lumen 111 is approximately 233% of the diameter of the lumen 121.

[0076] In one possible implementation, the diameter of the inner cavity 111 is not less than 200% of the diameter of the tube 121. Such a large difference in diameter ratio makes the buffering effect extremely significant. When liquid enters the wide inner cavity 111 from the narrow tube 121, its flow velocity is greatly reduced, kinetic energy is effectively dissipated, and the possibility of splashing is almost completely eliminated.

[0077] Based on the example of the dimensions above, the volume of the inner cavity 111 can be calculated to be approximately π × (7 / 2). 2 ×40≈1539, meaning the volume of the inner cavity 111 is approximately 1.54 ml.

[0078] To further ensure the effectiveness of the inner cavity 111 in reducing flow velocity, the volume of the inner cavity 111 can be configured to be no less than 300% of the volume of the tube 121. The volume of the inner cavity 111 can be the volume of the region bounded by the top edge of the connecting portion 130, the inner wall of the connecting portion 130, the inner wall of the first section 110, the inner wall of the transition section 140, and the bottom edge of the transition section 140. The volume of the tube 121 can be the volume of the region between the connection point of the inner wall of the second section 120 and the transition section 140 and the bottom opening of the gravity sphere 200; that is, the length of the second section 120 is the distance from the connection point with the transition section 140 to the bottom of the gravity sphere 200.

[0079] In one possible implementation, the volume of the inner cavity 111 is not less than 1.5 ml. A volume of not less than 1.5 ml means that the buffer cavity can hold a sufficient amount of rising liquid, providing stable and reliable splash protection for larger capacity bottles or hotter liquids.

[0080] In one possible implementation, the wall thickness of the first segment 110 is greater than 0.8 mm, for example, it is designed to be 1.0 mm, 1.1 mm, 1.5 mm, etc.

[0081] Because the inner cavity 111 of the first section 110 has a larger diameter and thicker walls, it can provide stronger structural support, effectively preventing deformation or collapse under negative pressure (i.e. when the user sucks), thus ensuring a constant buffer cavity volume and smooth sucking.

[0082] In this embodiment, the first section 110 and the second section 120 are made of the same material (e.g., silicone). The connecting part 130 is a separate component made of a material with higher hardness (e.g., PP material or silicone with higher hardness than the first and second sections).

[0083] In one possible implementation, the first segment 110 and the second segment 120 are made of the same material, for example, both the first segment 110 and the second segment 120 are made of silicone.

[0084] In one possible implementation, the material hardness of the second segment 120 is no greater than that of the material hardness of the first segment 110.

[0085] In one possible implementation, the material hardness of the first section 110 is not greater than the material hardness of the connecting part 130.

[0086] In one possible implementation, the first segment 110 and the connecting portion 130 are made of the same material; or, the first segment 110 and the second segment 120 are made of the same material; or, the connecting portion 130, the first segment 110 and the second segment 120 are all made of the same material, such as silicone.

[0087] Combination Figure 3 , Figure 4 As shown, its connection method adopts a three-section detachable structure:

[0088] Connection between the first section 110 and the connecting part 130: The top of the first section 110 has a radially outwardly extending expansion 112, and the top of the expansion 112 has a radially inwardly extending third annular protrusion 113, which together form a first groove 114. The independent connecting part 130 has two annular protrusions (a fourth annular protrusion 134 and a fifth annular protrusion 135), and its bottom fifth annular protrusion 135 is embedded into the first groove 114 to achieve a detachable connection with the hollow tube 100. The inner diameter of the connecting part 130 is the same as the diameter of the inner cavity 111.

[0089] Connection between the connecting part 130 and the suction component: A second groove 136 is formed between the fourth annular protrusion 134 and the fifth annular protrusion 135 on the upper part of the connecting part 130. The bottom of the suction component can be inserted into this second groove 136 to achieve a detachable connection with the connecting part 130.

[0090] This three-section, fully detachable design allows the hollow tube 100, connector 130, and suction component to be completely separated. Firstly, cleaning can reach every corner of every component, achieving true, thorough cleaning. Secondly, the use of a harder connector 130 makes the connection with the bottle cap and nipple more robust and durable, less prone to loosening due to repeated disassembly and reassembly.

[0091] In one possible implementation, the upper and lower portions of the connecting portion 130 have a first annular protrusion 131 and a second annular protrusion 133 extending radially outward, respectively, and an annular groove 132 is provided between the first annular protrusion 131 and the second annular protrusion 133; the bottom of the suction assembly is detachably embedded in the annular groove 132.

[0092] In one possible implementation, the top of the first segment 110 has a radially outwardly extending expansion 112, and the top of the expansion 112 has a radially inwardly extending third annular protrusion 113, the third annular protrusion 113 and the main body of the expansion 112 forming a first groove 114.

[0093] The upper and lower ends of the connecting portion 130 have a fourth annular protrusion 134 and a fifth annular protrusion 135 extending radially outward, respectively, and a second groove 136 is formed between the fourth annular protrusion 134 and the fifth annular protrusion 135.

[0094] The connecting part 130 is embedded in the first groove 114 through the fifth annular protrusion 135, so that the connecting part 130 and the hollow tube 100 form a detachable connection structure.

[0095] The bottom of the suction component is embedded in the second groove 136 so that the connecting part 130 and the suction component form a detachable connection structure.
