Description

Technical Field

[0001] The present application relates to the field of straws, and in particular to a straw head with multi-directional opening seams. Background Art

[0002] Straws are used to absorb liquids in containers and are widely used in daily life. Existing anti-choking straws seal the water outlet of the straw and then open a slit on the side wall of the straw to absorb liquids by biting the slit opening. However, the absorption capacity of existing straws is relatively small, and the biting range of the straws is small. If the user bites at other positions, the slit opening will be smaller or the slit will not open, making it difficult to absorb liquids in the container. In addition, excessive biting will easily make the inner wall of the tube stick closer or close, making the absorption capacity smaller or no liquid can be absorbed, affecting the use effect. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present application provides a multi-directional open-slit straw head.

[0004] The present application provides a multi-directional open-slit straw tip, which adopts the following technical solution:

[0005] A multi-directional open-slit straw head comprises a flexible pipe body with a water inlet at the bottom, and a valve arranged at the end of the flexible pipe body away from the water inlet. A water outlet is opened on the pipe wall of the flexible pipe body, and a control valve located at the water outlet is arranged on the flexible pipe body.

[0006] By adopting the above technical solution, the flexible tube body is convenient for the user to bite the tube body. When the user bites the flexible tube body, the valve and the control valve are squeezed and deformed. At this time, the valve and the control valve open the outlet for liquid flow. The valve and the control valve effectively increase the bite range on the flexible tube body, and biting and sucking water is easier. The user of this application can open the valve and the control valve at the same time by biting the flexible tube body, thereby increasing the water output of the flexible tube body and facilitating the user to suck.

[0007] Preferably, the control valve comprises a control portion 1 and a control portion 2 which are recessed toward the inner side of the flexible tube body, and a gap 1 for liquid circulation is formed between the control portion 1 and the control portion 2.

[0008] By adopting the above technical solution, control part one and control part two are used to control the opening and closing of gap one, which is convenient for synchronous opening and closing according to the bite state of the flexible pipe body. The control valve is arranged on the side, and the bite is opened to play an anti-choking role.

[0009] Preferably, the valve includes a control piece 1 and a control piece 2 arranged along the inner wall of the flexible tube body, the control piece 1 is arranged to be inclined downward toward the water inlet, the inclination direction of the control piece 2 is opposite to the inclination direction of the control piece 1, the distance between the control piece 1 and the control piece 2 gradually decreases near the water inlet, and the side of the control piece 1 close to the control piece 2 is tightly attached to the control piece 2 to form a gap 2.

[0010] By adopting the above technical solution, gap two is used for liquid circulation, control piece one and control piece two are convenient for users to control the opening and closing of the valve, and control piece one and control piece two are arranged relatively inclined. On the one hand, it is convenient for control piece one and control piece two to open and close along with the deformation state of the flexible tube body, while reducing the possibility of liquid leakage in the container. The valve bites open, which has an anti-choking effect; the valve is hollow, which is convenient for bite deformation, thereby driving the control valve to open.

[0011] Preferably, the valve comprises a control piece three and a control piece four arranged along the inner wall of the flexible tube body, and a side of the control piece three close to the control piece four is in close contact with the control piece four to form a gap three.

[0012] The present application provides a multi-directional open-slit straw tip, which adopts the following technical solution:

[0013] A multi-directional open-slit straw head comprises a flexible tube body with a water inlet at the bottom, and also comprises a valve arranged at the end of the flexible tube body away from the water inlet, a water outlet is opened on the tube wall of the flexible tube body, a control valve is arranged on the flexible tube body at the water outlet, and a fitting part is arranged on the flexible tube body within the bite range of the flexible tube body; after the flexible tube body is bitten and bitten to the fitting part, a gap for liquid circulation is left in the flexible tube body.

[0014] By adopting the above technical solution, the valve and the control valve increase the bite range, and the fitting portion is used to prevent excessive bite and reduce the possibility of fitting the inner wall of the pipe body.

[0015] Preferably, the control valve comprises a control part 1 and a control part 2 which are recessed toward the inner side of the flexible tube body, and a gap 1 for liquid circulation is formed between the control part 1 and the control part 2.

[0016] Preferably, the valve includes a control piece 1 and a control piece 2 arranged along the inner wall of the flexible tube body, the control piece 1 is arranged to be inclined downward toward the water inlet, the inclination direction of the control piece 2 is opposite to the inclination direction of the control piece 1, the distance between the control piece 1 and the control piece 2 gradually decreases near the water inlet, and the side of the control piece 1 close to the control piece 2 is tightly attached to the control piece 2 to form a gap 2.

[0017] Preferably, the valve comprises a control piece three and a control piece four arranged along the inner wall of the flexible tube body, and a side of the control piece three close to the control piece four is in close contact with the control piece four to form a gap three.

[0018] Preferably, the fitting portion comprises a fitting block 1 which is arranged on the inner wall of the flexible tube body and is located within the occlusal range of the flexible tube body, and a flow space 1 is formed between the fitting block 1 and the valve.

[0019] By adopting the above technical solution, the fitting block 1 is located on the inner wall of the flexible tube body. When the flexible tube body is bitten, the inner wall of the flexible tube body fits the fitting block 1. Empty channels for liquid flow are left on both sides of the fitting block 1. The flow space between the fitting block 1 and the valve is the same, which facilitates the liquid to flow out of the valve and avoids the fitting block 1 affecting the use of the valve.

[0021] By adopting the above technical solution, the second fitting block is located on the inner wall of the flexible tube body. When the user bites the straw, the tube wall of the flexible tube body contacts the second fitting block. The side wall of the flexible tube body is blocked by the second fitting block and cannot fit, leaving a channel for liquid flow. The second flow space is used for liquid to flow toward the valve.

[0022] Preferably, the fitting portion comprises a fitting block three arranged on the outer wall of the flexible pipe body, and a flow space three is left between the fitting block three and the control valve.

[0025] By adopting the above technical scheme, the fitting block four is arranged on the outer wall of the flexible tube body to prevent the user from over-biting the flexible tube body. The fitting block five contacts the inner wall of the flexible tube body when the flexible tube body is bitten, thereby preventing the inner wall of the flexible tube body from fitting together. A channel for liquid flow is left in the inner wall of the flexible tube body. The flow space four provides a flow channel for the liquid flowing out of the control valve, thereby reducing the influence of deformation on the control valve. The flow space five provides a liquid flow space to facilitate the flow of liquid.

[0026] Preferably, the fitting block five is provided with a groove two along the length direction of the flexible tube body.

[0027] By adopting the above technical solution, the groove 2 is used to expand the space between the fitting block 5 and the flexible tube body, thereby increasing the liquid flow rate.

[0028] Preferably, the fitting block five comprises a protrusion arranged on the inner wall of the flexible tube body and a fitting seat arranged on the inner wall of the flexible tube body and opposite to the protrusion, and the fitting seat is provided with a groove three along the length direction of the flexible tube body.

[0029] By adopting the above technical solution, the protrusion and the fitting seat are affected by the deformation of the flexible tube body, the protrusion will be inserted into the groove three, and a channel for liquid flow is left between the protrusion and the fitting seat on both sides and the flexible tube body, which is convenient for the flexible tube body to absorb liquid.

[0030] In summary, the valve and the control valve effectively increase the bite range of the flexible tube body, making it easier for the user to bite and absorb water; the fitting portion is used to prevent the user from over-biting the flexible tube body, effectively hindering the fitting of the inner wall of the flexible tube body.

DETAILED DESCRIPTION

[0064] The following is combined with Figure 1-Figure 32 This application is described in further detail.

[0065] Embodiment 1:

[0066] The present application embodiment discloses a multi-directional open seam straw head. Figure 1 and Figure 2 , comprising a flexible tube body 1 with a water inlet at the bottom, a valve 2 at the end of the flexible tube body 1 away from the water inlet, the valve 2 and the flexible tube body 1 are integrally formed, and the valve 2 is controlled to open and close by biting the flexible tube body 1. A water outlet 3 is opened on the side wall of the flexible tube body 1, and a control valve 4 is provided on the flexible tube body 1 at the water outlet 3, and the control valve 4 is integrally formed with the flexible tube body 1. When the user bites the flexible tube body 1, the valve 2 and the control valve 4 are opened to form multiple outlets, and the water output of the flexible tube body 1 is increased, which is convenient for the user to use the flexible tube body 1 to suck the liquid in the container.

[0067] Reference Figure 1 and Figure 2 In the embodiment of the present application, the flexible pipe body 1 is symmetrically provided with two control valves 4. In actual use, one or more control valves 4 may be provided. The control valve 4 includes a control portion 1 41 and a control portion 2 42 which are recessed toward the inner side of the flexible pipe body 1. The side of the control portion 1 41 close to the control portion 2 42 is in close contact with the control portion 2 42 to form a gap 1 5 for liquid circulation. The valve 2 includes a control sheet 1 21 and a control sheet 2 22 which are provided on the inner wall of the flexible pipe body 1. The side of the control sheet 1 21 close to the control sheet 2 22 is in close contact with the control sheet 2 22 to form a gap 2 6. When the flexible pipe body 1 is engaged, as the flexible pipe body 1 is deformed, the gap 2 6 opens to facilitate the outflow of liquid.

[0068] Reference Figure 1 and Figure 2 , the control piece 1 21 is tilted downward toward the water inlet, the tilt direction of the control piece 22 is opposite to that of the control piece 1 21, and the distance between the control piece 1 21 and the control piece 2 22 gradually decreases near the water inlet. After the flexible tube body 1 is inserted into the container, when the control piece 1 21 and the control piece 2 22 are subjected to upward pressure, since the control piece 1 21 and the control piece 2 22 are relatively tilted, the upward pressure makes the contact ends of the control piece 1 21 and the control piece 2 22 fit more closely, effectively preventing the liquid from leaking out of the flexible tube body 1.

[0069] The implementation principle of the multi-directional open-slit straw head of the embodiment of the present application is as follows: when the user bites the flexible tube body 1, the valve 2 and the control valve 4 open, and the gaps 1 5 and 2 6 open, which facilitates the outflow of liquid. The valve 2 and the control valve 4 are respectively arranged at the end and the side wall of the flexible tube body 1 of the present application, which effectively increases the bite range and facilitates the user to bite and absorb water; the flexible tube body 1 of the present application is easy to bite, the end valve 2 is hollow, and the tube wall control valve 4 is hollow. When the user bites the tube wall, the flexible tube body 1 is more easily deformed, thereby opening the valve 2 and the control valve 4, which is convenient for sucking the liquid in the container. The valve will only open when bitten, which has an anti-choking effect.

[0070] Embodiment 2:

[0071] The difference between the embodiment of the present application and the embodiment 1 is that: Figure 3 The valve 2 includes a control piece 3 23 and a control piece 4 24 arranged on the inner wall of the flexible pipe body 1. The side of the control piece 3 23 close to the control piece 4 24 is closely attached to the control piece 4 24 to form a gap 3 7. The control piece 3 23 or the control piece 4 24 is arranged on one side of the inner wall of the flexible pipe body 1 and is surrounded along the inner wall of the flexible pipe body 1, and is integrally formed with the flexible pipe body 1. In the embodiment of the present application, the control piece 3 23 and the control piece 4 24 are arranged in a flat manner. The side of the control piece 3 23 close to the control piece 4 24 is provided with an arc-shaped protrusion 1 facing the water inlet, and the control piece 4 24 is provided with a protrusion 2 closely attached to the protrusion 1, so as to prevent the flexible pipe body 1 from leaking liquid when it is not in use.

[0072] Embodiment three:

[0073] The difference between the embodiment of the present application and the embodiment 1 or the embodiment 2 is that: Figure 4 and Figure 5 The control part 1 41 and the control part 2 42 are recessed toward the inside of the flexible tube body 1 to form a groove, and the groove wall is convex in the flexible tube body 1. When the user bites the flexible tube body 1, the convex shape can prevent the tube wall of the flexible tube body 1 from being excessively fitted, making it easier for the liquid to flow out of the valve 2 and the control valve 4.

[0074] Embodiment 4:

[0075] The present application embodiment discloses a multi-directional open seam straw head. Figure 6 and Figure 7 , comprising a flexible pipe body 1 with a water inlet at the bottom, a valve 2 arranged at the end of the flexible pipe body 1 away from the water inlet, the valve 2 and the flexible pipe body 1 being integrally formed, a water outlet 3 being arranged on the pipe wall of the flexible pipe body 1, a control valve 4 located at the water outlet 3 being arranged on the flexible pipe body 1, the control valve 4 being integrally formed with the flexible pipe body 1, a fitting portion 8 located in the bite range of the flexible pipe body 1 being arranged on the flexible pipe body 1, the fitting portion 8 being integrally formed with the flexible pipe body 1. When the user bites the flexible pipe body 1, the valve 2 and the control valve 4 are opened due to the deformation of the flexible pipe body 1, the pipe wall of the flexible pipe body 1 contacts the fitting portion 8, the fitting portion 8 is used to prevent the pipe wall of the flexible pipe body 1 from being excessively fitted, and after the flexible pipe body 1 is bitten and the inner wall of the flexible pipe body 1 is fitted to the fitting portion 8, a gap is left in the inner cavity of the flexible pipe body 1, providing a passage state for liquid to flow.

[0076] Reference Figure 6 and Figure 7 The control valve 4 includes a control part 1 41 and a control part 2 42 arranged on the wall of the flexible pipe body 1. The control part 1 41 or the control part 2 42 is fixed on the wall of the flexible pipe body 1 and arranged along the wall of the flexible pipe body 1. The side of the control part 1 41 close to the control part 2 42 is tightly attached to the control part 2 42 to form a gap 5. When the flexible pipe body 1 is deformed by biting, the gap 5 opens.

[0077] Reference Figure 6 and Figure 7 The valve 2 includes a control piece 1 21 and a control piece 22 arranged on the inner wall of the flexible tube body 1. The control piece 1 21 or the control piece 22 is arranged on one side of the inner wall of the flexible tube body 1 and is arranged along the inner wall of the flexible tube body 1. The side of the control piece 1 21 close to the control piece 22 is closely attached to the control piece 22 to form a gap 26. When the flexible tube body 1 is engaged, the deformation of the flexible tube body 1 drives the gap 26 to open.

[0078] Reference Figure 6 and Figure 7 The control piece 1 21 is tilted downward toward the water inlet, the tilt direction of the control piece 22 is opposite to that of the control piece 1 21, and the distance between the control piece 1 21 and the control piece 2 22 gradually decreases near the water inlet. When the liquid is moved into the flexible tube body 1 under pressure, the liquid pushes the control piece 1 21 and the control piece 2 22, making the bottom ends of the control piece 1 21 and the control piece 2 22 more closely fitted, effectively preventing liquid leakage.

[0079] Reference Figure 6 and Figure 7The fitting part 8 is integrally formed with the flexible tube body 1, and the fitting part 8 includes a fitting block 81 disposed on the inner wall of the flexible tube body 1 and located within the occlusal range of the flexible tube body 1, and a flow space 811 is formed between the fitting block 81 and the valve 2. When the user bites the flexible tube body 1, the inner wall of the flexible tube body 1 contacts the fitting block 81, and the fitting block 81 prevents the inner wall of the flexible tube body 1 from being excessively fitted, and a channel for liquid circulation is left between the inner wall of the flexible tube body 1 and the fitting block 81.

[0080] Reference Figure 6 and Figure 7 In the embodiment of the present application, the bonding block 81 is arranged below the valve 2. In the specific implementation process, the bonding portion 8 can be arranged above the valve 2 or below the valve 2 according to the bite requirements, and also plays a role in preventing the inner wall of the flexible pipe body 1 from being overly bonded.

[0081] Embodiment five:

[0082] The difference between the present embodiment and the fourth embodiment is that: Figure 8 and Fig. 9 The valve 2 includes a control piece 3 23 and a control piece 4 24 arranged on the inner wall of the flexible tube body 1. The control piece 3 23 or the control piece 4 24 is fixed on one side of the inner wall of the flexible tube body 1 and arranged along the inner wall of the flexible tube body 1. The side of the control piece 3 23 close to the control piece 4 24 is tightly attached to the control piece 4 24 to form a gap 3 7. In the embodiment of the present application, the control piece 3 23 and the control piece 4 24 are arranged in a face-to-face manner. The end of the control piece 3 23 close to the control piece 4 24 is provided with a protrusion 1 located on the side of the control piece 3 23 facing the water inlet. The control piece 4 24 is fixed with a protrusion 2 that fits with the protrusion 1. The protrusion 1 and the protrusion 2 are in an arc shape. When the liquid enters the flexible tube body 1 from the water inlet under pressure, the liquid pushes the protrusion 1 and the protrusion 2 to fit more closely together, effectively preventing liquid leakage. The top of the fitting block 1 81 in the embodiment of the present application is horizontal, which facilitates the liquid to flow from the flow space 1 811 to the valve 2.
