Description

Technical Field

[0001] This invention belongs to the field of daily necessities technology, specifically relating to a straw structure, and more particularly to a snap-on straw structure with anti-slip function. Background Technology

[0002] A straw is a common drinking tool, widely used in various containers such as water cups, beverage cups, milk tea cups, and boxed beverages, allowing users to directly drink the liquid from the container.

[0003] During use, straws are typically inserted through a hole in the lid or the container opening, and then the beverage is drawn through the straw. However, existing straws generally have a problem: once inserted into the container, the straw's surface is usually quite smooth, and the only way to hold it in place is through friction between the straw and the lid hole or container opening, which is not very effective. During use, when the user tilts or moves the container, or when children pull on the straw, it easily slips into the container or even falls out completely. If the straw slips out, the user has to open the lid to remove it or replace it, which is extremely inconvenient. If the straw completely falls into the beverage, it needs to be retrieved by hand, which is not only inconvenient but also poses a hygiene risk.

[0004] To address the aforementioned issues, several existing technologies have proposed improvements. For example, a "non-detachable straw structure" adds a connector and clamping assembly between the straw and the cup lid, using a flared clip or spring to hold the straw in place, thus improving the connection's strength. Another example is an "anti-detachment straw" with a flared elastic block on the upper half of the straw body, utilizing the principle that the maximum outer diameter of the block's opening is larger than the inner diameter of the beverage container's straw insertion opening to prevent detachment. Yet another example is a "straw clip" that secures the straw by clamping it to the cup wall with an independent container holder and holding the straw tightly.

[0005] However, the aforementioned existing technologies still have the following shortcomings: First, the above solutions generally require the addition of independent clamping accessories in addition to the straw or special modifications to the cup lid, resulting in a relatively complex structure with many parts, which is not convenient for manufacturing and is also not conducive to cost control.

[0006] Secondly, in the existing technology, solutions such as horn-shaped locking blocks usually rely on a locking structure in one direction. Although this can prevent the straw from sliding down into the container, it is not enough to limit the straw from coming out of the container. The straw may still be accidentally pulled out of the container.

[0007] Third, the independent clamping accessories have poor compatibility with small-diameter straws, and the clamping force is difficult to control accurately: if the clamping force is too small, the anti-slip effect is insufficient, and if the clamping force is too large, the straw is easily jammed, making it impossible to adjust the straw up and down or even damaging the straw.

[0008] Fourth, existing technologies lack a simple design scheme that clearly defines the functions of the upper and lower contact parts—the lower contact part is responsible for elastically passing through the insertion hole, and the upper contact part is responsible for direct contact and limiting. Summary of the Invention

[0009] The purpose of this invention is to provide a snap-on straw structure to prevent slippage, which aims to solve the technical problem that existing straws easily slip into the container or accidentally come out of the container after being inserted, while taking into account the requirements of simple structure, low manufacturing cost, convenient use and bidirectional limiting.

[0010] To achieve the above objectives, the present invention provides the following technical solution: A snap-on straw structure to prevent slippage includes a straw body and a snap-on unit. The snap-on unit is disposed on the outer wall of the straw body and includes an upper abutment portion and a lower abutment portion. The lower abutment portion is elastically compressible to pass through a lid insertion hole in a container, and elastically returns to its original position after passing through the lid insertion hole. The upper abutment portion abuts against the upper side of the lid insertion hole after the lower abutment portion passes through it, thereby providing bidirectional axial restraint on the straw body and preventing axial slippage of the straw body.

[0011] The core of the above technical solution lies in the clear division of labor between the upper and lower abutment parts, each performing its specific function. The lower abutment part possesses elastic compression and recovery capabilities, its function being to "pass through" the cup lid's insertion hole; the upper abutment part, however, does not need the ability to elastically compress and pass through the insertion hole, its function being to "abut" against the upper side of the insertion hole after the lower abutment part has passed through. When the straw is subjected to a downward pushing force, the lower abutment part abuts against the lower side of the cup lid's insertion hole, preventing the straw from sliding further down into the container; when the straw is subjected to an upward pulling force, the upper abutment part abuts against the upper side of the cup lid's insertion hole, preventing the straw from detaching upward from the container. This forms a bidirectional axial limiting mechanism.

[0012] As a first specific structure of the lower abutment, the lower abutment includes a plurality of elastic protrusions, the elastic protrusions having a predetermined extension length along the axial direction of the straw body, and the plurality of elastic protrusions being spaced apart along the outer periphery of the straw body.

[0013] Furthermore, the elastic protrusion is an elongated strip extending along the axial direction of the straw body, with its radial dimension at the middle being larger than that at both ends. This shape allows the elastic protrusion to pass smoothly through the cup lid's insertion hole under uniform compression from the edge of the hole, and after passing through, it relies on elastic restoring force to form an effective axial limit.

[0014] As a second specific structure of the lower abutment, the lower abutment is an annular elastic retainer ring, which is arranged around the outer wall of the straw body, and the outer diameter of the annular elastic retainer ring is larger than the outer diameter of the straw body.

[0015] Furthermore, the radial dimension of the central part of the annular elastic retaining ring is larger than the radial dimensions of its upper and lower ends, giving it an overall drum-shaped profile. This drum-shaped profile further optimizes the smoothness of its passage through the socket and the limiting effect after recovery.

[0016] As a preferred structure of the upper abutment, the upper abutment includes a sheet nested outside the straw body. The inner side of the sheet is connected to the straw body, and the outer dimension of the sheet is larger than the size of the cup lid insertion hole. This sheet can be a ring-shaped structure, a polygonal structure, or other shapes, as long as its outer dimension is larger than the size of the cup lid insertion hole, it can reliably abut against the upper side of the cup lid insertion hole after the lower abutment passes through it. The sheet itself does not need to have the function of elastically deforming through the insertion hole, therefore it can be made of rigid or semi-rigid materials.

[0017] Furthermore, the upper abutment portion also includes an annular sealing rib, which is connected to the lower part of the sheet body and is used to form an interference fit with the cup lid insertion hole. The annular sealing rib enhances the sealing effect between the upper abutment portion and the cup lid insertion hole, preventing liquid from splashing out of the insertion hole; on the other hand, it increases the radial stability of the straw and reduces the shaking of the straw during use.

[0018] As a further optimization, the lower end of the straw body is provided with an anti-detachment end, the outer diameter of which is larger than the outer diameter of the straw body. The function of the anti-detachment end is that when the straw body moves upward, the anti-detachment end can be blocked by the lower abutment part or the edge of the cup lid insertion hole, serving as a last line of defense to prevent the straw body from completely detaching from the container under accidental strong pulling.

[0019] In terms of manufacturing methods, this invention provides two solutions: In one implementation, the snap-fit ​​unit and the straw body are integrally molded. This integral molding can be achieved through single injection molding, two-color injection molding, or two-stage injection molding, resulting in a simple manufacturing process suitable for mass production and good overall structural integrity.

[0020] In another embodiment, the snap-fit ​​unit and the straw body are separate assembly structures. The straw body includes upper and lower sections, and the snap-fit ​​unit has a socket hole through which it is fitted and fixed to the outer wall of the straw body. Specifically, the upper and lower straw sections are inserted into the socket holes from the upper and lower sides of the snap-fit ​​unit, respectively, or the snap-fit ​​unit is pre-fitted onto the lower straw section and then connected to the upper straw section. This separate structure is particularly suitable for upgrading existing straws to prevent slipping and also facilitates user disassembly and cleaning.

[0021] Both the buckle unit and the straw body are made of food-grade materials, such as food-grade polypropylene (PP), food-grade polyethylene (PE), biodegradable PHA material, and food-grade silicone.

[0022] Compared with the prior art, the beneficial effects of the present invention are: 1. Significant bidirectional limiting effect: This invention utilizes a clearly defined upper and lower abutment part—the lower abutment part is responsible for elastically passing through the insertion hole and abutting against the lower side, while the upper abutment part directly abuts against the upper side of the insertion hole—to form an axial bidirectional limiting effect on the straw. Whether the straw is subjected to a downward pushing force (sliding into the container) or an upward pulling force (coming out of the container), it can be effectively limited, completely solving the problems of straw slippage and accidental pullout.

[0023] 2. Simple structure and easy to manufacture: The upper abutment part of this invention adopts a sheet structure nested outside the straw body, eliminating the need for complex elastic mechanisms; the lower abutment part can use an elastic protrusion or an annular elastic retaining ring. The overall structure is simple, and mass production can be achieved through one-piece molding, resulting in low manufacturing costs and facilitating large-scale promotion.

[0024] 3. Rational division of functions and high reliability: The upper contact part does not need to pass through the insertion hole, so it does not rely on elastic deformation and can adopt a more robust structural design, making it less prone to damage over long-term use; the lower contact part is specifically responsible for elastic insertion and can use highly elastic materials to optimize the insertion experience. Each part performs its own function, resulting in higher overall reliability than solutions where a single structure performs both functions.

[0025] 4. Good compatibility and easy to use: The lower abutment is designed with a certain degree of flexibility to adapt to cup lid holes of different diameters; the upper abutment only needs to ensure that the outer dimension of the plate is larger than the hole size. Users only need to insert the straw normally into the container for automatic anti-slip fixation, without any additional operation; when removing the straw, the lower abutment is compressed again to remove it, and the upper abutment does not affect the insertion and removal action under normal use.

[0026] 5. Enhanced sealing performance: By setting an annular sealing rib on the lower part of the upper contact section, an interference fit can be formed with the cup lid insertion hole, which not only enhances the leak-proof effect but also improves the stability of the straw.

[0027] 6. Flexible modular design: The modular assembly structure allows the snap-fit ​​unit to be disassembled, making it easy to clean and also facilitating the anti-slip upgrade of existing ordinary straws. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1 like Figure 1 and Figure 2 As shown, a snap-on straw structure to prevent slippage includes a straw body 1 and a snap-on unit 2. The snap-on unit 2 is disposed on the outer wall of the straw body 1 and includes an upper abutment portion 21 and a lower abutment portion 22.

[0039] The upper contact portion 21 includes a sheet 211 nested outside the straw body 1. The sheet 211 is annular, and its inner side is fixedly connected to the outer wall of the straw body 1. It can be formed by integral molding, gluing, or interference fit. The outer diameter of the sheet 211 is larger than the inner diameter of the cup lid insertion hole 31. The sheet 211 is made of food-grade PP material with a certain degree of rigidity and does not require elastic deformation.

[0040] The lower abutment portion 22 includes four elastic protrusions 221, the specific number of which can be set from 2 to 8 as needed. The four elastic protrusions 221 are evenly spaced along the outer periphery of the straw body 1. Each elastic protrusion 221 is an elongated strip structure extending along the axial direction of the straw body 1. In the extending direction, the radial dimension of the elastic protrusion 221 is the largest in the middle, and the radial dimension gradually decreases at the upper and lower ends, forming an arc-shaped or spindle-shaped profile. The elastic protrusions 221 are made of elastic materials such as food-grade silicone or TPE, and are integrally molded with the straw body 1 through secondary injection molding.

[0041] In this embodiment, the upper abutment portion 21 and the lower abutment portion 22 are spaced apart along the axial direction of the straw body 1, with a predetermined distance between them, which is slightly larger than the thickness of the cup lid insertion hole 31.

[0042] Operating principle: When the user inserts the straw body 1 into the cup lid insertion hole 31 on the cup lid 3, the elastic protrusion 221 of the lower abutment part 22 first contacts the cup lid insertion hole 31. Because the upper radial dimension of the elastic protrusion 221 is small, it can easily enter; as insertion continues, the middle part of the elastic protrusion 221 is radially compressed by the edge of the cup lid insertion hole 31 and contracts inward, allowing the cup lid insertion hole 31 to pass through. After the elastic protrusion 221 has completely passed through the cup lid insertion hole 31, it returns to its normal shape under the action of elastic restoring force. At this time, the plate 211 of the upper abutment part 21 is exactly located on the upper side of the cup lid insertion hole 31 and abuts against the upper surface of the cup lid 3, while the elastic protrusion 221 of the lower abutment part 22 abuts against the lower side of the cup lid insertion hole 31. When the straw body 1 is subjected to a downward pushing force, the elastic protrusion 221 abuts against the lower edge of the cup lid insertion hole 31, preventing the straw from continuing to slide down; when the straw body 1 is subjected to an upward pulling force, the piece 211 abuts against the upper surface of the cup lid 3, preventing the straw from coming off upward. This forms a bidirectional axial limiting mechanism.

[0043] To remove the straw, simply pull upwards to compress the elastic protrusion 221 through the cup lid socket 31. At this time, the blade 211 moves upwards with the straw. Because its outer diameter is larger than the socket size, it cannot pass through the socket. Therefore, the blade 211 will remain above the cup lid 3. The user needs to misalign the blade 211 with the socket or continue to apply force. Only when the blade 211 is made of a flexible or deformable material can it be completely removed. This further enhances the safety against accidental drop.

[0044] Example 2 like Figure 3 As shown, the main difference between this embodiment and Embodiment 1 lies in the structure of the lower abutment portion 22. In this embodiment, the lower abutment portion 22 adopts an annular elastic retaining ring 222. The annular elastic retaining ring 222 is arranged around the outer wall of the straw body 1, and its outer diameter is larger than the outer diameter of the straw body 1. The radial dimension of the annular elastic retaining ring 222 is the largest in the middle, and the radial dimension gradually decreases at the upper and lower ends, forming an overall drum-shaped profile.

[0045] The annular elastic retainer 222 is made of food-grade silicone material and has good elasticity. During manufacturing, the straw body 1 is first injection molded, and then the silicone annular elastic retainer 222 is fixed to the outer wall of the straw body 1 through secondary injection molding or overmolding process.

[0046] The structure of the upper contact portion 21 is the same as that in Embodiment 1.

[0047] In this embodiment, the annular elastic retaining ring 222 provides smoother and more uniform compression deformation when passing through the cup lid insertion hole 31, resulting in less wear on the cup lid insertion hole 31. After recovery, it provides a more stable and uniform axial limiting force. Other working principles are basically the same as in Embodiment 1.

[0048] Example 3 like Figure 4 As shown, this embodiment further optimizes the upper abutment portion 21 based on Embodiment 1. In addition to the sheet body 211, the upper abutment portion 21 also includes an annular sealing rib 212. The annular sealing rib 212 is disposed on the lower surface of the sheet body 211, connected to the lower part of the sheet body 211, and surrounds it circumferentially.

[0049] The outer diameter of the annular sealing rib 212 is slightly larger than the inner diameter of the cup lid insertion hole 31. When the straw body 1 is inserted into place and the blade 211 abuts against the upper surface of the cup lid 3, the annular sealing rib 212 extends into the cup lid insertion hole 31 and forms an interference fit with the inner wall of the insertion hole.

[0050] The advantages of this design are as follows: on the one hand, the interference fit between the annular sealing rib 212 and the cup lid insertion hole 31 can prevent the liquid in the container from splashing out or leaking from the insertion hole, thus enhancing the sealing effect; on the other hand, the interference fit also increases the stability of the straw in the radial direction, reducing the shaking of the straw during use.

[0051] In this embodiment, the annular sealing rib 212 can be integrally formed with the sheet 211, and the material can be the same as that of the sheet 211, such as PP, or different, such as silicone soft rib. Other structures and working principles are basically the same as in Embodiment 1.

[0052] Example 4 like Figure 5 As shown, in this embodiment, based on Embodiment 1, an anti-detachment end 4 is added to the lower end of the straw body 1. The outer diameter of the anti-detachment end 4 is larger than the outer diameter of the straw body 1, but smaller than the maximum outer diameter of the lower abutment portion 22, or is equivalent to the maximum outer diameter of the lower abutment portion 22.

[0053] The function of the anti-detachment tip 4 is as follows: In extreme cases, if the straw body 1 is unexpectedly pulled upwards with great force, causing the lower abutment portion 22 to be forcibly compressed and pass through the cup lid insertion hole 31, the straw body 1 may be about to completely detach from the container. The anti-detachment tip 4 will abut against the lower side of the cup lid insertion hole 31 or be blocked by the lower abutment portion 22, serving as a last line of defense to prevent the straw body 1 from completely detaching from the container. At the same time, the anti-detachment tip 4 can also prevent the straw from detaching from the bottom of the container when inserted too deeply.

[0054] The anti-detachment end 4 can be integrally formed with the straw body 1, or it can be fixed by separate assembly. Other structures and working principles are basically the same as in Embodiment 1.

[0055] Example 5 like Figure 7 As shown, the difference between this embodiment and the previous embodiment is that the snap-fit ​​unit 2 and the straw body 1 are separate assembly structures, and the straw body 1 includes an upper straw 11 and a lower straw 12. The snap-fit ​​unit 2 has a central sleeve hole 5.

[0056] The overall structure of the snap-fit ​​unit 2 is as follows: the upper abutment part 21 is a sheet 211 with an outer diameter larger than the inner diameter of the cup lid insertion hole 31; the lower abutment part 22 is a ring-shaped elastic retaining ring 222 with a drum-shaped profile; the two are integrally formed into a snap-fit ​​component, with a through socket 5 in the center. The inner diameter of the socket 5 is slightly smaller than the outer diameter of the straw body 1.

[0057] During assembly, first, the snap-fit ​​unit 2 is fitted onto the upper end of the lower straw 12 through the socket 5 and secured with an interference fit. Then, the lower end of the upper straw 11 is inserted into the upper part of the socket 5, aligning the upper straw 11 with the lower straw 12. The upper straw 11 and lower straw 12 can be further secured using methods such as insertion, threaded connection, or adhesive. Finally, the snap-fit ​​unit 2 is clamped and fixed between the upper straw 11 and the lower straw 12.

[0058] The advantages of this embodiment are: the buckle unit 2 can be manufactured separately and then assembled with any straw that meets the size requirements, which makes it easy to upgrade the existing straw to be non-slip; at the same time, the buckle unit 2 can be removed from the straw, making it easy to clean separately and avoiding hygiene dead corners.

[0059] Usage Status Overview like Figure 6 The diagram shows a cross-sectional view of the anti-slip snap-on straw structure of the present invention after it has been inserted into the cup lid 3. The straw body 1 passes through the cup lid insertion hole 31 of the cup lid 3 and extends into the container. The lower abutment part 22 has passed through the cup lid insertion hole 31 and elastically returned to its normal shape, abutting against the lower side of the cup lid insertion hole 31; the plate 211 of the upper abutment part 21 abuts against the upper surface of the cup lid 3, that is, the upper side of the cup lid insertion hole 31. In this state, the axial displacement of the straw body 1 relative to the cup lid 3 is completely restricted—it is blocked downward by the lower abutment part 22 and upward by the upper abutment part 21. No matter how the user moves the container or what direction the straw is subjected to force, the straw will not slip into the container or accidentally come out of the container, providing a good user experience.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
