Description

Technical Field

[0001] This application relates to the field of packaging, and more particularly to a bottle nozzle and bottle with an automatic closing valve core. Background Technology

[0002] Beverages, jellies, and other food products are usually packaged in bags or bottles. Specifically, the bottle opening and cap are made of plastic. The threads on the cap and the threads on the bottle opening work together to seal the bag or bottle and prevent the food from leaking out.

[0003] When beverages or jelly are not finished, the bottle cap should be sealed to the bottle opening in a timely manner to prevent external contaminants from entering the packaging bag or bottle through the bottle opening, thereby reducing food contamination. After the bottle opening is opened, the bottle cap separates from the bottle opening, which can easily lead to the bottle cap being lost and unable to be found in time to seal the bottle opening.

[0004] Therefore, how to design a bottle nozzle that can seal the bottle opening in a timely manner has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0006] A bottle nozzle with an automatic sealing valve core is provided, including a bottle mouth, a thrust-resistant part and a first sealing surface on the inner wall of the bottle mouth cavity; The valve body is installed between the thrust portion and the first sealing surface. The valve body includes a valve seat, a valve core, and an elastic element. The elastic element is installed between the valve seat and the valve core, and its two ends are respectively connected to the valve seat and the valve core. The valve seat abuts against the thrust part, and the elastic element pushes the valve core to fit against the first sealing surface, thereby sealing the bottle opening.

[0007] In one embodiment, the valve core peripheral wall is provided with a plurality of support portions extending radially outward along the valve core, the peripheral wall of the support portion abutting against the inner wall of the bottle mouth cavity, and two adjacent support portions forming a flow guiding channel.

[0008] In one embodiment, the bottle mouth end wall is provided with a sealing part extending radially toward one side of the bottle mouth axis. The sealing part has an opening, and a first sealing surface is provided on the side wall of the opening. When the valve body is installed in the inner cavity of the bottle mouth, the elastic element pushes the valve core into the opening, and the second sealing surface on the valve core abuts against the first sealing surface to achieve the sealing of the opening.

[0009] In one embodiment, a bottle cap is included, and the bottle cap is threadedly connected to the threads on the outer wall of the bottle opening.

[0010] In one embodiment, the end wall of the sealing part is provided with a sealing ring groove that is recessed inward along the axial direction of the bottle mouth, and the inner wall of the bottle cap is provided with a first sealing retaining ring that is arranged along the axial direction of the bottle mouth. When the bottle cap is installed on the bottle mouth, the first sealing retaining ring is inserted into the sealing ring groove, and the side wall of the first sealing retaining ring abuts against the inner wall of the sealing ring groove.

[0011] In one embodiment, the top wall of the valve core is provided with a sealing platform, and the inner wall of the bottle cap is provided with a second sealing ring arranged along the axial direction of the bottle mouth. When the bottle cap is installed on the bottle mouth, the end wall of the second sealing ring abuts against the sealing platform.

[0012] In one embodiment, the thrust relief part includes a plurality of thrust blocks, which are evenly distributed circumferentially along the axis of the bottle mouth and fixedly connected to the inner wall of the bottle mouth cavity. The thrust blocks are provided with a first guide surface and a first thrust surface.

[0013] In one embodiment, the valve seat is annular, and the valve seat is provided with a second guide surface and a second thrust surface. The second guide surface is inclined and close to the elastic element, and the second thrust surface is horizontal and away from the elastic element. When the valve body is installed in the inner cavity of the bottle mouth, the second thrust surface abuts against the first thrust surface.

[0014] In one embodiment, the valve body is made of plastic, and the elastic element includes a plurality of elastic threads that are evenly distributed around the axis of the valve seat. The elastic element also includes a reinforcing ring that is fixedly connected to the plurality of elastic threads.

[0015] A bottle includes a bottle body and a spout mounted on the bottle body, the spout being the aforementioned type.

[0016] Compared with the prior art, the bottle spout and bottle with an automatic sealing valve core disclosed in this application have the following advantages: This application installs a valve body inside the bottle opening cavity. By applying pressure to the valve core, the elastic element is compressed, causing the valve core to separate from the first sealing surface, thus opening the bottle opening. When the pressure on the valve core is released, the elastic element pushes the valve seat against the thrust stop, preventing the valve body from falling out of the bottle opening cavity. The elastic element pushes the valve core towards the first sealing surface, causing the valve core to fit against the first sealing surface, thereby sealing the bottle opening. Compared with the prior art, this solves the problem of bottle caps being easily lost and unable to seal the bottle opening in a timely manner, reduces the risk of food being contaminated by external sources, and the sealing between the valve core and the first sealing surface solves the problem of food leakage at the bottle opening.

[0021] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] A typical bottle nozzle consists of a bottle neck and a cap. The cap is threaded onto the bottle neck to create a seal, preventing food from leaking out of the bottle or bag. This also reduces the risk of food contamination.

[0023] Example 1: This embodiment provides a technical solution that mainly achieves rapid sealing of the bottle opening, reducing the risk of the bottle cap separating from the bottle opening, the bottle cap being lost, and the bottle opening not being able to be sealed in time.

[0024] like Figure 1 As shown, this application includes a bottle opening 1 and a valve body 2 installed in the inner cavity of the bottle opening 1, and the valve body 2 is used to achieve rapid sealing of the bottle opening 1.

[0025] Specifically, such as Figure 2 As shown, a thrust portion 11 and a first sealing surface 12 are provided in the inner wall of the inner cavity of the bottle mouth 1. The valve body 2 is installed between the thrust portion 11 and the first sealing surface 12. The valve body 2 is made of plastic material and can undergo elastic deformation after being subjected to external thrust.

[0026] Furthermore, the valve body 2 includes a valve seat 21, a valve core 22, and an elastic element 23. The elastic element 23 is installed between the valve seat 21 and the valve core 22. The two ends of the elastic element 23 are fixedly connected to the valve seat 21 and the valve core 22, respectively. When the valve body 2 is installed in the inner cavity of the bottle opening 1, the valve seat 21 abuts against the thrust portion 11 to prevent the valve body 2 from falling out of the inner cavity of the bottle opening 1. The elastic element 23 pushes the valve core 22 to abut against the first sealing surface 12 to seal the bottle opening 1, thereby preventing leakage at the bottle opening 1.

[0027] The usage process is as follows: When it is necessary to open the bottle mouth 1, an external force can be applied to the valve core 22 to press the valve core 22 into the inner cavity of the bottle mouth 1. Since the valve seat 21 abuts against the thrust part 11, the valve seat 21 and the bottle mouth 1 remain relatively stationary at this time. The elastic element 23 is compressed, and the valve core 22 disengages from the first sealing surface 12. At this time, the bottle mouth 1 is opened, and the food in the packaging bag or bottle can be poured out.

[0028] The food here can be liquid, a mixture of solid and liquid, or granular solid, such as seasonings like chicken essence, monosodium glutamate, and salt.

[0029] After the pressure on the valve core 22 is released, the elastic element 23 pushes the valve core 22 back to its original position. At this time, the valve core 22 fits against the first sealing surface 12, achieving a quick seal at the bottle opening 1 and reducing the risk of food contamination.

[0030] Example 2: This embodiment is an improvement based on Embodiment 1.

[0031] Specifically, such as Figure 3 As shown, a sealing part 10 is provided at the end wall of the bottle mouth 1, extending radially towards one side of the axis of the bottle mouth 1. The sealing part 10 has an opening 101 that extends vertically through it, allowing food to be poured out from the opening 101. A first sealing surface 12 is provided on the side wall of the opening 101. The first sealing surface 12 is arc-shaped. When the valve body 2 is installed in the inner cavity of the bottle mouth 1, the peripheral wall of the valve core 22 abuts against the first sealing surface 12, thereby sealing the opening 101.

[0032] The thrust relief part 11 includes a plurality of thrust relief blocks 111. In this embodiment, four sets of thrust relief blocks 111 are provided and evenly distributed along the circumference of the bottle mouth 1. They are fixedly installed on the inner wall of the inner cavity of the bottle mouth 1. The thrust relief blocks 111 are located on the side away from the sealing part 10. The thrust relief blocks 111 are provided with a first guide surface 1111 and a first thrust surface 1112. The first guide surface 1111 is located on the side away from the sealing part 10, and the first thrust surface 1112 is located on the side close to the sealing part 10.

[0033] When the valve body 2 is installed in the inner cavity of the bottle mouth 1, the valve seat 21 of the valve body 2 abuts against the first thrust surface 1112, thereby preventing the valve body 2 from detaching from the bottle mouth 1.

[0034] like Figure 2 and Figure 4 As shown, the valve seat 21 of the valve body 2 is arranged in a ring shape. Food in the packaging bag or bottle can move to the opening 101 side through the hole in the middle of the valve seat 21, which facilitates the flow of food in the inner cavity of the bottle mouth 1.

[0035] Furthermore, the valve seat 21 is provided with a second guide surface 211 and a second thrust surface 212, such as... Figure 2 As shown, the second guide surface 211 is close to the valve core 22, and the second thrust surface 212 is away from the valve core 22. The second guide surface 211 forms an angle with the horizontal plane so as to cooperate with the first guide surface 1111 of the thrust block 111 to assist in the installation of the valve seat 21. The second thrust surface 212 is set parallel to the horizontal plane.

[0036] With the above settings, as Figure 5As shown, the valve body 2 is inserted into the inner cavity of the bottle mouth 1 from the end away from the opening 101. The valve core 22 and the elastic element 23 pass through the thrust block 11 and extend inward in sequence. Then, the second guide surface 211 of the valve seat 21 abuts against the first guide surface 1111 of the thrust block 111, thereby pushing the valve seat 21 to deform so that the valve seat 21 passes over the thrust block 111. The valve core 22 abuts against the first sealing surface 12, and the elastic element 23 is squeezed and deformed. Then, the second thrust surface 212 abuts against the first thrust surface 1112 to restrict the valve seat 21 from coming out of the inner cavity of the bottle mouth 1.

[0037] Specifically, in this embodiment, such as Figure 4 As shown, the peripheral wall of the valve core 22 is provided with a second sealing surface 222, wherein the second sealing surface 222 is arc-shaped and adapted to the first sealing surface 12. After the valve body 2 is installed in the inner cavity of the bottle mouth 1, the second sealing surface 222 of the valve core 22 fits against the first sealing surface 12 on the bottle mouth 1, as shown. Figure 6 As shown, this achieves a seal on opening 101.

[0038] It is worth noting that when the valve core 22 is compressed by an external force onto the elastic element 23, in order to allow the food to pour out from the opening 101 of the bottle mouth 1 and reduce the obstruction of the valve core 22 to the food, in this embodiment, as follows: Figure 2 and Figure 5 As shown, the peripheral wall of the valve core 22 is provided with a plurality of support portions 221 extending radially outward along the valve core 22. The end wall of the support portion 221 away from the axis of the valve core 22 abuts against the inner wall of the bottle mouth 1. When the valve core 22 moves along the axial direction of the bottle mouth 1, the end wall of the support portion 221 slides against the inner wall of the bottle mouth 1. By using the support portion 221 to abut against the inner wall of the bottle mouth 1, the stability of the movement of the valve core 22 can be improved.

[0039] In this embodiment, six support portions 221 are provided and are evenly distributed around the valve core 22, and a flow guide channel 24 is formed between two adjacent support portions 221.

[0040] With the above settings, when the valve core 22 is compressed by an external force on the elastic element 23, the opening 101 opens, such as... Figure 7 As shown, at this time, the food inside the packaging bag or bottle will flow out through the hole on the valve seat 21 and the flow channel 24 from the opening 101.

[0041] Furthermore, such as Figure 6 As shown, after the valve body 2 is installed in the inner cavity of the bottle mouth 1, the valve core 22 extends into the opening 101, thereby sealing the opening 101.

[0042] In this embodiment, in order to further seal the bottle opening 1, such as... Figure 2 and Figure 5As shown, it also includes a bottle cap 3, wherein the bottle cap 3 is threadedly connected to the thread on the outer wall of the bottle mouth 1.

[0043] like Figure 2 and Figure 3 As shown, the end wall of the sealing part 10 is provided with a sealing ring groove 102 that is recessed along the axial direction of the bottle mouth 1. The inner wall of the bottle cap 3 is provided with a first sealing retaining ring 31. When the bottle cap 3 is installed on the bottle mouth 1, the first sealing retaining ring 31 is inserted into the sealing ring groove 102, and the end wall of the first sealing retaining ring 31 abuts against the inner wall of the sealing ring groove 102, thereby strengthening the seal of the bottle cap 3 on the bottle mouth 1.

[0044] Furthermore, such as Figure 2 and Figure 4 As shown, a sealing platform 223 is provided on the top wall of the valve core 22, wherein the sealing platform 223 extends into the opening 101, and a second sealing ring 32 extending into the opening 101 is provided on the inner wall of the bottle cap 3, wherein the end wall of the second sealing ring 32 abuts against the sealing platform 223.

[0045] In this embodiment, as Figure 2 and Figure 4 As shown, the elastic element 23 includes a plurality of elastic threads 231, wherein the plurality of elastic threads 231 are evenly distributed around the valve seat 21. In this embodiment, two elastic threads 231 are provided, and the two ends of the elastic threads 231 are fixedly connected to the valve core 22 and the valve seat 21 respectively. The elastic element 23 also includes a reinforcing ring 232, wherein the reinforcing ring 232 is horizontally arranged, and both elastic threads 231 are fixedly connected to the reinforcing ring 232, thereby maintaining the stability of the elastic threads 231.

[0046] Specifically, the valve seat 21, valve core 22, elastic thread 231 and reinforcing ring 232 are made by an integral molding process, and the elastic thread 231 can rebound on its own after being released from compression.

[0047] Example 3: This embodiment designs a bottle, such as Figure 8 As shown, it includes a bottle body 100 and a bottle spout installed on the bottle body 100. Specifically, the bottle spout in this embodiment is the bottle spout from the above embodiment two.

[0048] like Figure 6 and Figure 7As shown, the outer wall of the bottle mouth 1 is provided with a sealing part 14, wherein the sealing part 14 is located above the thrust block 111. The bottle mouth 1 is provided with a flow-increasing hole 13 that connects the inner cavity of the bottle mouth 1 and the outer wall of the bottle mouth 1. The flow-increasing hole 13 is located between the sealing part 14 and the thrust block 111. After the bottle mouth is installed on the packaging bottle or packaging bag, the sealing part 14 is fixedly connected to the bottle body 100 or the bag body so that the flow-increasing hole 13 is located in the inner cavity of the bottle body 100 or the inner cavity of the bag body. At this time, the food in the packaging bottle or packaging bag can flow into the inner cavity of the bottle mouth 1 through the flow-increasing hole 13, thereby accelerating the flow of the food.

[0049] In this embodiment, the valve core installed in the inner cavity of the bottle opening 1 can automatically seal the bottle opening 1 in a timely manner, reducing the risk of food leakage at the bottle opening 1.

[0050] This example uses bottles or bags containing liquid food, placed upside down. Figure 9 As shown, it includes a push rod 103, which abuts against the valve core 22, thereby pushing the valve core 22 to open the opening 101. At this time, the fluid in the packaging bag or packaging bottle will flow out from the opening 101.

[0051] A standard bottle spout is inverted and inserted into the push rod 103 to allow the fluid inside the packaging bag to flow out. When the spout detaches from the push rod 103, the spout opening 101 cannot close in time, easily causing the fluid to continue flowing out. This can be compared to the situation of a large bottled water container inverted on a water dispenser.

[0052] In this embodiment, after the bottle nozzle gradually disengages from the push rod 103, the valve core 22 will gradually close the opening 101 under the pushing action of the elastic element 23, reducing the risk of fluid leakage from the packaging bag or bottle.
