[0006] A drinking nozzle, on which a liquid outlet hole is provided;

[0007] A bottle body, on which a through hole for connecting the internal environment of the bottle body with the external atmospheric environment of the bottle body is provided, and the drinking nozzle can be installed on the bottle body through the bottle mouth of the bottle body;

[0008] A bladder, which is used to hold liquid, is arranged in the bottle body, and the top of the bladder is provided with an opening that cooperates with the bottle mouth of the bottle body. In the assembled state of the bottle body and the drinking nozzle, a sealed inner cavity for holding liquid is formed between the bladder and the drinking nozzle;

[0009] A one-way valve, which is installed in the liquid outlet hole, and the flow direction of the one-way valve is from the inside of the bladder to the outside of the bladder.

[0010] In some embodiments of this application, a ring-shaped support portion is provided along the opening at the top of the bladder. In the assembled state of the drinking nozzle and the bottle body, the ring-shaped support portion is pressed between the drinking nozzle and the bottle body to form the sealed inner cavity.

[0011] In some embodiments of this application, the bladder is made of a thin-film elastic material, and the ring-shaped support portion and the bladder are of an integral structure.

[0012] In some embodiments of this application, an installation cover for fixing the outer periphery of the drinking nozzle is provided on the outer periphery of the drinking nozzle, and the installation cover is detachably connected to the opening of the bottle body.

[0013] In some embodiments of the present application, the mounting cap is provided with an internal thread, and the mouth of the bottle body is provided with an external thread, and the mounting cap is threadedly connected to the bottle body.

[0014] In some embodiments of the present application, it includes a bottle cap, the bottle cap is detachably connected to the mounting cap, and in the closed state of the bottle cap, the drinking nozzle is located inside the bottle cap.

[0015] In some embodiments of the present application, a plurality of raised ribs are provided on the inner circumference of the drinking nozzle, the top end of the raised rib is connected to the inner wall of the drinking nozzle, and the bottom end of the raised rib extends into the interior of the bladder for supporting the bladder.

[0016] In some embodiments of the present application, the top end of the raised rib extends into the liquid outlet hole along the inner wall of the drinking nozzle, and the bottom of the raised rib extends away from the liquid outlet hole towards the outer circumference of the drinking nozzle.

[0017] In some embodiments of the present application, the liquid outlet hole is located at the central position of the drinking nozzle, and a plurality of the raised ribs are uniformly arranged along the inner circumference of the drinking nozzle with the liquid outlet hole as the center.

[0018] In some embodiments of the present application, a plurality of the through holes are arranged at intervals along the circumferential direction of the bottle body at the bottom of the bottle body.

[0019] One of the technical solutions in the above technical solutions has at least one of the following advantages or beneficial effects: The bladder of the drinking utensil is soft and easy to clean and replace. The bottle body can protect the bladder inside it from being punctured or scratched. The through holes on the bottle body enable the inside and outside of the bottle body to remain in a conductive state, allowing air to flow freely in and out of the bottle body. The one-way valve has a one-way conduction function. Liquid can only flow from the inside of the bladder to the outside of the bladder through the one-way valve. When sucking on the drinking nozzle, the liquid inside the bladder can flow out through the drinking nozzle, but external air cannot flow into the bladder through the drinking nozzle. When in use, install the drinking nozzle, bottle body, and bladder. A sealed inner cavity for holding liquid is formed between the bladder and the drinking nozzle. When filling with liquid, the liquid can fill the bladder. When sucking on the drinking nozzle, a negative pressure is formed at the drinking nozzle. At this time, atmospheric pressure can enter the bottle body through the gaps on the bottle body and exert an atmospheric pressure on the bladder. Under the action of atmospheric pressure, the liquid in the bladder is squeezed by the atmosphere and flows out through the liquid outlet hole of the drinking nozzle via the one-way valve, thus realizing the function of drinking the liquid in the bladder. When stopping sucking, at this time, both the drinking nozzle and the inside of the bottle body are in an atmospheric pressure state, and the pressures of the two are balanced. The one-way valve automatically closes under the action of the elasticity of its own material, and air cannot flow into the bladder through the drinking nozzle, thereby preventing air from entering the bladder and ensuring that the inside of the bladder is all in a liquid state (at this time, it can maintain the state that the inside of the bladder is all liquid without air), enabling the liquid in the bladder to be immediately sucked when sucking again next time. This bladder-shaped container can be used to drink water, beverages, milk, and other liquids. When in use, there is no need to clean the bottle body, and only the bladder needs to be replaced or cleaned, which is convenient for carrying out. It effectively reduces the risk of inhaling excessive air during multiple suckings.

[0029] An embodiment of the present application provides a drinking utensil. Refer to Figure 1 、 Figure 2 and Figure 3 , which includes a drinking nozzle 100, and a liquid outlet hole 110 is provided on the drinking nozzle 100;

[0030] a bottle body 200, and a through hole 210 is provided on the bottle body 200 to connect the internal environment of the bottle body 200 with the external atmospheric environment. The drinking nozzle 100 can be installed on the bottle body 200 through the bottle mouth of the bottle body 200;

[0031] a bladder 300, which is used to hold liquid. The bladder 300 is arranged inside the bottle body 200. The top of the bladder 300 is provided with an opening that cooperates with the bottle mouth of the bottle body 200. In the assembled state of the bottle body 200 and the drinking nozzle 100, a sealed inner cavity for holding liquid is formed between the bladder 300 and the drinking nozzle 100;

[0032] The one-way valve 120 is installed in the liquid outlet hole 110, and the flow direction of the one-way valve 120 is from the inside of the bladder 300 to the outside of the bladder 300.

[0033] The bladder 300 of the drinking utensil is soft and easy to clean and replace. The bottle body 200 can protect the bladder 300 inside it from being punctured or scratched. The through hole 210 on the bottle body 200 enables the inside and outside of the bottle body 200 to be in a conductive state, and air can freely flow in and out of the bottle body 200. The one-way valve 120 has a one-way conduction function. Liquid can only flow through the one-way valve 120 from the inside of the bladder 300 to the outside of the bladder 300. When sucking the drinking nozzle 100, the liquid inside the bladder 300 can flow out through the drinking nozzle 100, but the outside air cannot flow into the bladder 300 through the drinking nozzle 100. When in use, install the drinking nozzle 100, the bottle body 200 and the bladder 300. A closed inner cavity for containing liquid is formed between the bladder 300 and the drinking nozzle 100. When filling with liquid, the liquid can fill the bladder 300. When sucking the drinking nozzle 100, a negative pressure is formed at the drinking nozzle 100. At this time, the atmospheric pressure can enter the bottle body 200 through the gap on the bottle body 200 and act on the bladder 300 with atmospheric pressure. Under the action of the atmospheric pressure, the liquid in the bladder 300 is squeezed by the atmosphere and flows out from the liquid outlet hole 110 of the drinking nozzle 100 through the one-way valve 120, thus realizing the function of drinking the liquid in the bladder 300; when stopping sucking, at this time, both the drinking nozzle 100 and the inside of the bottle body 200 are in the state of atmospheric pressure, and the pressures of the two are balanced. The one-way valve 120 automatically closes under the action of the elasticity of its own material, and air cannot flow into the bladder 300 through the drinking nozzle 100, thereby preventing air from entering the bladder 300 and ensuring that the inside of the bladder 300 is all in a liquid state (at this time, the state that the inside of the bladder 300 is all liquid without air can be maintained), so that the liquid in the bladder 300 can be immediately sucked when sucking next time. This bladder-shaped container can be used to drink water, beverages, milk and other liquids. When in use, it is not necessary to clean the bottle body 200, and only the bladder 300 needs to be replaced or cleaned, which is convenient for carrying out. It effectively reduces the risk of inhaling excessive air during multiple suckings and is more suitable for infants and young children.

[0034] See Figure 3 At the top of the bladder 300, a ring-shaped support portion 310 is provided along the opening. The ring-shaped support portion 310 can be installed at the opening of the bottle body 200. The bladder 300 is installed inside the bottle body 200 through 310 and will not fall off in the state of containing liquid. In the assembled state of the drinking nozzle 100 and the bottle body 200, the ring-shaped support portion 310 is pressed between the drinking nozzle 100 and the bottle body 200 to form a closed inner cavity, avoiding the liquid in the bladder 300 from spilling out.

[0035] In some embodiments, the bladder 300 is made of a thin-film elastic material and can deform as the liquid inside the bladder 300 changes. The annular support portion 310 and the bladder 300 are an integral structure made of the same material. Therefore, the annular support portion 310 has a certain elasticity. When the annular support portion 310 is pressed tightly between the drinking nozzle 100 and the bottle body 200, it acts like a sealing ring and plays a sealing role. At the same time, the annular support portion 310 can also facilitate the installation of the bladder 300 inside the bottle body 200. It can be stretched or contracted and deformed, and is used to hold drinking liquid. Specifically, in some embodiments, after the drinking utensil is installed, the annular support portion 310 is stuck at the top of the bottle mouth of the bottle body 200, and the top of the annular support portion 310 is tightly connected to the drinking nozzle 100. It can be understood that the thin-film elastic materials include but are not limited to the following: such as rubber (natural rubber, synthetic rubber, etc.), plastics (polyethylene (PE), polypropylene (PP), etc.), elastic fibers (spandex), polytetrafluoroethylene (PTFE), silicone rubber, etc. These thin-film elastic materials have a small thickness and weight, are flexible in use, have good portability, and can withstand deformations such as stretching, compression, and bending and return to their original state, having good elastic recovery ability. The production process is relatively simple, the cost is low, and the thin-film elastic material has good light transmittance, which can conveniently show the amount of liquid in the bladder 300 when using the drinking utensil, facilitating the user to intuitively understand the remaining amount of liquid in the bladder 300.

[0036] See Figure 1 and Figure 2 An installation cover 400 for fixing the outer periphery of the drinking nozzle 100 is provided on the outer periphery of the drinking nozzle 100. The installation cover 400 is detachably connected to the opening of the bottle body 200. The installation cover 400 fixedly connects the drinking nozzle 100, the bladder 300, and the bottle body 200 together, making the overall structure of the drinking utensil stable and convenient for disassembly and assembly, and suitable for people of various ages.

[0037] In some embodiments, the installation cover 400 is provided with internal threads, and the bottle mouth of the bottle body 200 is provided with external threads. The installation cover 400 is threadedly connected to the bottle body 200. It can be understood that in another embodiment, the installation cover 400 and the bottle body 200 are connected by a buckle to achieve the purpose of facilitating installation.

[0038] The drinking utensil further includes a bottle cap 500. The bottle cap 500 is detachably connected to the installation cover 400. In the closed state of the bottle cap 500, the drinking nozzle 100 is located inside the bottle cap 500. When not drinking the liquid, the bottle cap 500 is covered to prevent the liquid from leaking out of the drinking nozzle 100, and at the same time, it can prevent dust from contaminating the drinking nozzle 100, making the drinking utensil convenient for carrying and storing.

[0039] See Figure 1 and Figure 2, there are multiple raised ribs 130 on the inner circumference of the drinking nozzle 100. The top of the raised rib 130 is connected to the inner wall of the drinking nozzle 100, and the bottom of the raised rib 130 extends into the interior of the bladder 300 to support the bladder 300. When the bladder 300 covers the drinking nozzle 100 and makes it impossible to suck, the liquid in the bladder 300 can smoothly flow out through the liquid outlet hole 110. It can be understood that the raised rib 130 is made of a relatively soft material and will not damage the bladder 300.

[0040] See Figure 1 and Figure 2 , the top of the raised rib 130 extends along the inner wall of the drinking nozzle 100 into the liquid outlet hole 110, and the bottom of the raised rib 130 extends away from the liquid outlet hole 110 towards the outer circumference of the drinking nozzle 100. That is, there are multiple raised ribs 130 designed around the liquid outlet hole 110 of the drinking nozzle 100. The function of these raised ribs 130 is that when the liquid in the bladder 300 is almost sucked out, the bladder 300 will be squeezed to the liquid outlet hole 110 under the action of the atmospheric pressure. At this time, the edge of the raised rib 130 can support the membranous bladder 300, so that a gap is formed between the bladder 300 and the inner wall of the drinking nozzle 100, preventing the bladder 300 from completely covering the liquid outlet hole 110 of the drinking nozzle 100 and causing the drinking nozzle 100 to be blocked and unable to suck out the liquid anymore.

[0041] In some embodiments, see Figure 1 and Figure 2 , the liquid outlet hole 110 is located at the central position of the drinking nozzle 100, and multiple raised ribs 130 are evenly arranged along the inner circumference of the drinking nozzle 100 with the liquid outlet hole 110 as the center. Such a structural setting is reasonable, which can fully support the bladder 300 and completely avoid the situation where the bladder 300 covers the drinking nozzle 100 and makes it impossible to suck.

[0042] It can be understood that the drinking nozzle 100 can be designed into different structures, which can be a nipple for infants to suck or a drinking mouthpiece for adults. The drinking nozzle 100 is installed above the port of the bladder 300, forming a sealed inner cavity with the bladder 300. That is, the drinking nozzle 100 and the bladder 300 form a closed container after installation.

[0043] In some embodiments, the drinking nozzle 100 is made of a soft material, and the liquid outlet hole 110 is designed in a straw shape and conducts with the lower part of the drinking nozzle 100, so that the drinking nozzle 100 can be held in the mouth for sucking. A one-way valve 120 is designed in the liquid outlet hole 110. The one-way valve 120 is an inverted V-shaped one-way valve. When sucking, a negative pressure state is formed at the drinking nozzle 100, and since there is a through hole 210 provided at the flat bottom of the bottle body 200 to conduct with the atmosphere, the bottle body 200 can maintain the state of atmospheric pressure. The atmospheric pressure is greater than the negative pressure at the drinking nozzle 100, so the liquid in the bladder will be squeezed by the atmospheric pressure and flow to the drinking nozzle through the one-way valve 120.

[0044] A plurality of through holes 210 are arranged at intervals in the circumferential direction of the bottle body 200 at the bottom of the bottle body 200, so that the atmospheric pressure can smoothly enter the inside of the bottle body 200 through the bottom of the bottle body 200, which is convenient for applying uniform pressure to the bladder 300 when sucking the drinking nozzle 100. It can be understood that the through holes 210 can be set in various shapes for the purpose of balancing the air pressure inside and outside the bottle body 200.
