[0003] The present disclosure provides a straw and a straw cup, which can increase the service life of the straw through a separation structure formed by a second petal body and an inner side wall.

[0004] A first aspect of the present disclosure provides a straw, comprising a tube body and a valve, wherein the valve is arranged inside the straw.

[0005] The valve comprises two valve flaps arranged relatively tilted;

[0006] The same valve flap comprises a first flap body and a second flap body, wherein a first edge of the first flap body is fixedly connected to a first end of the second flap body, and the other edges of the first flap body are fixedly connected to the inner wall of the tube body, and the second ends of the two second flap bodies are pressed against each other to form a one-way valve for unidirectionally conducting liquid; along the length direction of the two second flap bodies, when the second flap bodies are squeezed, a channel is formed between the two second flap bodies;

[0007] The two second petals are separated from the inner wall of the tube body.

[0008] In one embodiment, the included angle between the second flap body and the first flap body of the same valve flap is not equal to 180 degrees.

[0009] In one embodiment, the inclination angle of the second flap body of the same valve flap relative to the reference line is smaller than the inclination angle of the first flap body relative to the reference line, and the reference line is the central axis of the tube body.

[0010] In one embodiment, the valve flap is inclined from the inner side wall of the tube body toward a direction away from the liquid outlet end of the straw for outflowing liquid.

[0011] In one embodiment, the maximum thickness of the second petal body is less than or equal to the minimum thickness of the first petal body.

[0012] In one embodiment, along the direction from the inner wall of the tube body to the central axis of the tube body, the thickness of the first petal body gradually decreases; and / or the thickness of the second petal body gradually decreases.

[0031] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0032] The valve of the straw in the related art is directly connected to the side wall of the straw, which causes the straw to be damaged by the biting force generated when the straw is bitten, and the service life of the straw is short.

[0033] In order to solve the above technical problems, an embodiment of the present disclosure provides a straw. The straw includes a tube body and a valve, and the valve is arranged inside the straw. The valve includes two valve flaps arranged relatively obliquely; wherein the same valve flap includes a first flap body and a second flap body, the first edge of the first flap body is fixedly connected to the first end of the second flap body, the other edges of the first flap body are fixedly connected to the inner wall of the tube body, and the second ends of the two second flap bodies are pressed against each other to form a one-way valve for unidirectionally conducting liquid; along the length direction of the two second flap bodies, when the second flap bodies are squeezed, a channel is formed between the two second flap bodies, and the two second flap bodies are separated from the inner wall of the tube body. According to the scheme of the present disclosure, the service life of the straw can be improved by the separation structure formed by the second flap body and the inner wall.

[0034] The present disclosure provides a straw, such as Figures 1 to 4 As shown, the straw comprises a tube body 1 and a valve 2, and the valve 2 is arranged inside the straw.

[0035] The valve 2 includes two valve flaps arranged at a relative angle; wherein the same valve flap includes a first flap body 3 and a second flap body 4, the first edge of the first flap body 3 is fixedly connected to the first end of the second flap body 4, and the other edges of the first flap body 3 are fixedly connected to the inner wall of the tube body 1; and the second ends of the two second flap bodies 4 are pressed against each other to form a one-way valve for unidirectionally conducting liquid; along the length direction of the two second flap bodies 4, when the second flap bodies 4 are squeezed, a channel is formed between the two second flap bodies 4; the two second flap bodies 4 are separated from the inner wall of the tube body 1.

[0036] The position of valve 2 relative to tube body 1 is Figure 2For example, the valve 2 can be located in the upper half of the tube body 1 (including the liquid outlet end of the straw). Optionally, the position of the valve 2 can be adaptively adjusted with reference to ergonomic principles or according to the user population. For example, if the user population is infants and young children, the oral cavity of the infants and young children is relatively small and the teeth have not yet fully grown, the valve 2 can be set at a distance of 0.5 to 1.5 cm from the liquid outlet end of the tube body 1; if the user population is children, the valve 2 can be set at a distance of 1.5 to 2.5 cm from the liquid outlet end of the tube body 1. It should be noted that in the present disclosure, the distance between the valve 2 and the liquid outlet end of the tube body 1 is not specifically limited.

[0037] The same valve flap includes a first flap body 3 and a second flap body 4. Figure 2 and Figure 4 For example, the first edge of the first petal body 3 is fixedly connected to the first end of the second petal body 4, and the other edges of the first petal body 3 are fixedly connected to the inner wall of the tube body 1. The first petal body 3 is fixedly connected to the inner wall of the tube body 1 along the circumference of the inner wall of the tube body 1, the edge located in the hollow part of the tube body 1 is the first edge, and the part fixedly connected to the inner wall of the tube body 1 is the other edge.

[0038] The two second flaps 4 are separated from the inner wall of the tube body 1, and the second ends of the second flaps 4 of the two valve flaps are pressed against each other to form a one-way valve for one-way conduction of liquid, wherein the first end and the second end of the same second flap 4 are opposite ends. During use, when the user squeezes the second flap 4 along the length direction of the two second flaps 4, a channel is formed between the two second flaps 4. At this time, the second ends of the second flaps 4 of the two valve flaps are pressed against each other to form a one-way circulation valve in an open state. When the straw is not in use, the one-way circulation valve is in a closed state. It should be noted that the first end and the second end of the same first flap 3 are opposite ends, and the first end and the second end of the same second flap 4 are opposite ends.

[0039] As an implementation method, Figure 2 As shown, in the two second petals 4 , the ends other than the first end and the second end are fixedly connected, so that a channel for liquid to enter and exit is formed only between the second ends of the two second petals 4 .

[0040] The sizes of the first petal body 3 and the second petal body 4 may be adapted to the size of the tube body 1 , or to the size of a straw cup including a straw.

[0041] It can be understood that the two second petals 4 are separated from the inner wall of the tube body 1, that is, the two second petals 4 are not connected to the inner wall of the tube body 1, and there is a certain distance between the two second petals 4 and the inner wall of the tube body 1. This separated structure can reduce the conduction of force, help reduce the impact of the bite force on the valve 2, and make the valve 2 not easily bitten, thereby greatly improving the service life of the straw. At the same time, the separated structure can also reduce the supporting force between the valve 2 and the inner wall of the tube body 1, so that the user can use the straw to absorb liquid more easily.

[0042] According to the embodiment of the present disclosure, the two second petals 4 are separated from the inner wall of the tube body 1, so that there is a certain buffer area between the second petals 4 and the inner wall of the tube body 1. The second petals 4 do not need to directly bear all the force, but disperse and reduce the bite force through this buffer area, so that the valve 2 is not easily bitten, thereby improving the durability of the straw.

[0043] like Figure 2 As shown, the valve 2 can be understood as adding a "V-shaped" folding surface to a "V-shaped" structure, and the "V-shaped" structure is formed by two first valve bodies 3 fixedly connected to the inner wall of the tube body 1; the "V-shaped" folding surface is formed with two second valve bodies 4. The first valve body 3 is fixedly connected to the inner wall of the tube body 1, the second valve body 4 is fixedly connected to the first valve body 3, and the second valve body 4 is separated from the inner wall of the tube body 1, so that the second valve body 4 is connected to the inner wall of the tube body 1 to form a separated structure. When the valve 2 in the tube body 1 is subjected to an external bite force, the transmission of the bite force is reduced, so that the valve 2 is not easily bitten, thereby greatly improving the service life of the straw.

[0044] It should be noted that the inner side wall of the tube body 1 and the other edges of the first petal body 3 can be connected in various ways, for example, by an integrated connection, or by an adaptive connection structure. For example, in one embodiment, the inner side wall of the tube body 1 and the other edges of the first petal body 3 are fixedly connected by an adhesive. It should be noted that the adhesive must at least meet the following conditions:

[0045] 1. Environmental protection and food safety;

[0046] 2. Temperature resistance;

[0047] 3. Chemical stability.

[0048] Here, the type of adhesive is not specifically limited, and the adhesive used in the embodiment of this solution only needs to meet the above conditions.

[0049] In addition, the fixed connection method of the first end of the second petal body 4 and the first edge of the first petal body 3 may also adopt the above-mentioned connection form.

[0050] When applying the eyedropper, the eyedropper can include the following states:

[0051] Initial (one-way valve closed) state: the two second flaps 4 are in a state of no force, and the valve 2 forms a tight sealing structure through the mutual pressure of the two second flaps 4. This sealing structure can effectively prevent water or other liquids from flowing out of the liquid outlet end of the straw.

[0052] Extrusion process: When external pressure is applied along the length direction of the two second petals 4, the second petals 4 will deform. The two second petals 4 will form a channel due to the deformation, so that the originally sealed one-way valve is opened, forming a channel that allows liquid to pass through. The width and length of this channel depend on the size of the external pressure (bite force) and the material properties of the second petals 4. Optionally, the second petals 4 are made of silicone. Of course, the material of the second petals 4 is not limited here, and it can also be other elastic and deformable materials.

[0053] Liquid outflow: Once the channel is formed, the liquid can flow out through the channel by the suction force applied by the user to the straw. This process may be continuous or intermittent, depending on the stability of the external pressure and the recovery of the second valve body 4.

[0054] In a specific implementation, the straw provided in the embodiment of the present disclosure is made of an elastic material such as silicone.

[0055] In one embodiment, the included angle between the second flap body 4 and the first flap body 3 of the same valve flap is not equal to 180 degrees.

[0056] According to the embodiments of the present disclosure, it should be noted that:

[0057] The included angle between the second flap body 4 and the first flap body 3 of the same valve flap can be understood as Figure 2 The angle formed at the connection between the second flap 4 and the first flap 3. In the application straw, the angle between the second flap 4 and the first flap 3 of the same valve flap is not equal to 180 degrees, which can make the second flap 4 thinner and reduce the supporting force, and can also ensure the sealing effect of the one-way valve, preventing the liquid from flowing out of the liquid outlet of the straw through the valve when the user does not apply force.

[0058] In one embodiment, Figure 2 As shown, the inclination angle of the second flap body 4 of the same valve flap relative to the reference line is smaller than the inclination angle of the first flap body 3 relative to the reference line, and the reference line is the central axis of the tube body 1.

[0059] According to the embodiments of the present disclosure, it should be noted that:

[0060] The baseline can be understood as Figure 2The central axis of the tube body 1 is also the tube axis of the straw. In the tube body 1 of the straw, the tube axis extends along the long axis direction of the straw. The first petal 3 has an inclination angle θ relative to the reference line (tube axis). 1 The second petal 4 also has an inclination angle θ relative to the reference line (tube axis) 2 , but the inclination angle θ of the second petal body 4 2 Smaller than the inclination angle θ of the first petal 3 1 The size of the inclination angle will affect the sealing performance of the one-way valve. The inclination angle of the second flap body 4 is smaller than that of the first flap body 3, so that the second ends of the two second flap bodies 4 can have a better pressing effect, thereby making the formed one-way valve more sealed and preventing liquid from flowing out of the liquid outlet end of the straw when no external force is applied to the second flap body 4.

[0061] According to an embodiment of the present disclosure, by designing the inclination angle of the second flap body 4 of the same valve flap relative to the baseline to be smaller than the inclination angle of the first flap body 3 relative to the baseline, the sealing performance of the straw in an unstressed state can be improved; and the smoothness of the liquid flow in the straw in a stressed state can be improved.

[0062] It is understandable that Figure 2 As shown, if the two first petals 3 are regarded as forming an inclined "funnel" structure, and the second petal 4 is regarded as forming a "V-shaped" folded surface, then the "V-shaped" folded surface and the inner wall of the tube body 1 are a separate structure. This separate structure can make the second petal 4 thinner and lighter, reduce the support force of the straw side wall on the second petal 4, and make it easier and less laborious for the user to use the straw to suck liquid; in addition, due to the increase in the folded surface, the sealing effect of the one-way valve can be guaranteed, preventing the liquid from flowing out of the liquid outlet of the straw through the valve when the user does not apply force.

[0063] In one embodiment, the valve flap is inclined from the inner side wall of the tube body 1 toward the direction away from the liquid outlet end of the straw for liquid to flow out. Figure 4 The directions shown are subject to Figure 4 The upper part of the middle tube body 1 is the liquid outlet.

[0064] In one embodiment, the maximum thickness of the second petal body 4 is less than or equal to the minimum thickness of the first petal body 3 .

[0065] According to the embodiments of the present disclosure, it should be noted that:

[0066] The first flap 3 and the second flap 4 respectively assume different functions. For example, the first flap 3 may focus more on flow control, while the second flap 4 may focus more on preventing backflow or acting as a one-way valve. Among them, the thickness design of the flap is usually based on its required strength, durability and flexibility. For the first flap 3 that needs to withstand greater pressure or requires higher strength, its minimum thickness will be greater than the maximum thickness of the second flap 4 that requires more flexibility and less pressure bearing capacity. However, by designing the maximum thickness of the second flap 4 to be less than or equal to the minimum thickness of the first flap 3, the second flap 4 can have better elasticity than the first flap 3, so that when the bite force is low, the liquid in the cup can be easily sucked out; at the same time, the water sealing effect can be guaranteed to avoid the safety hazards caused by the gushing out of special liquids. Exemplarily, the situation where the bite force is low may include: the user is an infant or a patient. The special liquid may include: a liquid with a higher temperature or a liquid that can be dyed.

[0067] According to the embodiment of the present disclosure, the maximum thickness of the second petal body 4 is less than or equal to the minimum thickness of the first petal body 3, which can improve the elasticity and thus enhance the comfort of use of the straw; at the same time, it can ensure the water sealing effect and thus enhance the safety of the straw.

[0068] In one embodiment, along the direction from the inner wall of the tube body 1 to the central axis of the tube body 1 , the thickness of the first petal body 3 gradually decreases; and / or the thickness of the second petal body 4 gradually decreases.

[0069] According to the embodiments of the present disclosure, it should be noted that:

[0070] The gradual decrease in the thickness of the first flap 3 of the straw means that starting from the connection with the inner wall of the tube body 1, the thickness of the first flap 3 gradually decreases, forming a gradually thinning design. This design can maintain the strength of the first flap at a specific position and the flexibility at other positions. Specifically, the thickness of the part where the first flap 3 is connected to the inner wall of the tube body 1 is the largest, and then the closer to the position where it is connected to the second flap 4, the thinner it is, which can ensure that the thickness of the valve 2 at the first position where the bite force is contacted and the position where the bite force is the largest is larger, thereby improving the durability of the valve 2; at the same time, the maximum thickness of the second flap 4 is less than or equal to the minimum thickness of the first flap 3, so that the connection between the first flap 3 and the second flap 4 can be adaptive and beautiful.

[0071] The thickness of the second petal 4 gradually decreases from the first end to the second end of the second petal 4 along the inner wall of the tube body 1 to the central axis of the tube body 1. The gradually thinning second petal 4 helps to control the flow of liquid at a specific position, and can also make the second petal 4 thinner and lighter, reducing the supporting force of the side wall of the straw on the second petal 4, so that the user can use the straw to suck liquid more easily and effortlessly.

[0072] In one embodiment, the length of the first petal body 3 is greater than the length of the second petal body 4 .

[0073] According to the embodiments of the present disclosure, it should be noted that:

[0074] The length of the first petal 3 is the first threshold, and the length of the second petal 4 is the second threshold. Here, the first threshold and the second threshold can be adaptively designed or adjusted according to the size of the straw, which is not limited here.

[0075] According to an embodiment of the present disclosure, the length of the first petal 3 is greater than that of the second petal 4, which can improve the stability of the fixed connection between the first petal 3 and the inner wall of the tube body 1, thereby improving the stability of the second petal 4, which in turn helps to improve the quality of the straw.

[0076] In one embodiment, the first petal body 3 and the second petal body 4 are integrally formed.

[0077] According to the embodiments of the present disclosure, it should be noted that:

[0078] During processing, the first flap body 3 and the second flap body 4 are combined to obtain a valve flap, and the two valve flaps constitute the valve 2. Specifically, if the first flap body 3 and the second flap body 4 are thermoplastic materials, a certain amount of thermoplastic material can be heated and softened, and then put into a mold to obtain an integrally formed valve 2 (including the first flap body 3 and the second flap body 4).

[0079] According to the embodiment of the present disclosure, the first petal body 3 and the second petal body 4 are integrally formed to avoid liquid leakage caused by a gap at the connection between the first petal body 3 and the second petal body 4, thereby improving the sealing and safety of the straw.

[0080] In one embodiment, the tube body 1 and the valve 2 are integrally formed.

[0081] According to the embodiments of the present disclosure, it should be noted that:

[0082] During processing, the tube body 1 and the valve 2 are combined to obtain a straw. Specifically, if the tube body 1 and the valve 2 are thermoplastic materials, a certain amount of thermoplastic material can be heated and softened, and then put into a mold to obtain an integrally formed straw (including the tube body 1 and the valve 2).

[0083] According to the embodiments of the present disclosure, the integrally formed design of the tube body 1 and the valve 2 can avoid the problem of liquid leakage caused by the gap at the connection between the tube body 1 and the valve 2, thereby improving the sealing and safety of the straw.
