Technical Field
[0001] This utility model relates to the technical field of liquid holding containers, specifically a bottle body. Background Technology
[0002] In the packaging of food and pharmaceuticals, the gaseous environment inside the container is crucial, including dryness, oxygen content, and carbon dioxide content, which determine the shelf life of food and pharmaceuticals. For solid food or pharmaceuticals, a bagged gas absorbent can be placed directly inside the container. However, for liquid food or pharmaceuticals, it is not possible to place a gas absorbent directly inside the container.
[0003] Most pharmaceutical solvents have high requirements for the content of carbon dioxide, oxygen, or other gases in the gas, requiring that it not exceed a preset value. However, some special pharmaceutical solvents themselves emit carbon dioxide or oxygen, causing the content of a certain gas in the bottle to continuously increase, affecting the quality of the pharmaceutical solvent. Utility Model Content
[0004] This utility model addresses the aforementioned problems. Its purpose is to provide a bottle that can absorb specific gases within the bottle, reducing the content of those specific gases, while also preventing the gas absorbent from directly contacting the liquid and thus avoiding damage to the liquid's quality.
[0005] To achieve the above objectives, this utility model provides a bottle body, including a bottle body and an inner plug. The bottle body is provided with a first receiving cavity, and the inner plug is detachably installed at the opening of the bottle body to seal the first receiving cavity. The inner plug includes an inner plug body and a water-resistant and breathable membrane disposed at the bottom of the inner plug body. The inner plug body has a second receiving cavity with an opening facing the first receiving cavity. The water-resistant and breathable membrane is disposed at the opening of the second receiving cavity. The second receiving cavity contains a gas absorbent.
[0006] According to the bottle body described above, the water-blocking and breathable membrane is provided with a plurality of first vent holes, the first vent holes penetrating the upper and lower end faces of the water-blocking and breathable membrane, and the diameter of the first vent holes is between 0.1-10μm.
[0007] According to the bottle body described above, the water-resistant and breathable membrane is made of polyurethane material.
[0008] According to the bottle body described above, a positioning groove is provided on the side of the second receiving cavity, and a positioning ring is provided on the outer side of the gas absorbent, the positioning ring being able to extend into the positioning groove.
[0009] According to the bottle body described above, the water-resistant and breathable membrane is installed onto the inner plug body by ultrasonic welding.
[0010] According to the bottle body described above, the inner plug body is provided with an air inlet channel, and a plurality of the air inlets are arranged at intervals along the circumference of the inner plug body. The air inlets are used to connect the first receiving cavity and the second receiving cavity to allow gas in the first receiving cavity to enter the second receiving cavity.
[0011] According to the bottle body described above, the inner plug body is provided with a first sealing part and a second sealing part located at its lower part. The first sealing part is located above the second sealing part. A plurality of air inlets are located on the first sealing part. A gap is provided between the second sealing part and the opening of the bottle body. The air inlets communicate with the first receiving cavity through the gap.
[0012] According to the bottle body described above, the minimum diameter of the gap is between 0.1 and 10 μm.
[0013] According to the bottle body described above, the diameter of the first sealing part is equal to the diameter of the bottle body opening, and an air guide groove is provided at the connection between the first sealing part and the second sealing part. One end of the air inlet is located in the air guide groove, and the air guide groove is used to connect the air inlet and the gap.
[0014] The bottle body described above also includes a cap, which is fastened to the inner plug and together with the inner plug body to form a third receiving cavity. The top of the inner plug body is provided with a plurality of second vent holes, which connect the third receiving cavity and the second receiving cavity. The air inlet is connected to the third receiving cavity.
[0015] This utility model has the following beneficial effects: 1. A gas absorbent is provided in the first accommodating cavity of the inner plug body, and a water-resistant and breathable membrane is used to separate the first accommodating cavity from the second accommodating cavity. That is, gas can enter the first accommodating cavity through the water-resistant and breathable membrane, while liquid is blocked and cannot enter the first accommodating cavity. This can achieve the adsorption of specific gases and avoid the gas absorbent from contaminating the liquid. 2. An air inlet is also provided on the inner stopper body. The gas inside the bottle can be transferred to the second receiving cavity through the air inlet, which can effectively avoid the disadvantage of gas not being able to be transferred due to the blockage of the pores in the water-resistant and breathable membrane. 3. The gap between the second sealing part and the bottle opening is maintained between 0.1-10μm, which is much smaller than the diameter of a water droplet. This allows gas to pass through while blocking liquid from passing through, preventing liquid from entering the second receiving cavity through this gap. Attached Figure Description

Detailed Implementation
[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0019] like Figure 1-5 As shown, a bottle includes a bottle body 100, an inner plug 200, and a cap. The bottle body 100 has a first receiving cavity 110 for holding liquid food or medicine. The inner plug 200 is detachably installed at the opening of the bottle body 100 to seal the first receiving cavity 110 and prevent liquid from flowing out. The cap is used for secondary sealing and also serves as an anti-tampering device. By breaking the cap, it can be determined whether the bottle has been opened, preventing unauthorized entry of other items.
[0020] In this embodiment, the inner plug 200 includes an inner plug body 210 and a water-resistant and breathable membrane 220 disposed at the bottom of the inner plug body 210. The inner plug body 210 has a second receiving cavity 211 with an opening facing the first receiving cavity 110. The water-resistant and breathable membrane 220 is disposed at the opening of the second receiving cavity 211, that is, the water-resistant and breathable membrane 220 can separate the first receiving cavity 110 and the second receiving cavity 211. The characteristic of the water-resistant and breathable membrane 220 is that gas can pass through smoothly, but liquid cannot pass through the water-resistant and breathable membrane 220, so that the bottle body is free of liquid. Regardless of the orientation, the liquid in the first receiving cavity 110 cannot enter the second receiving cavity 211. The second receiving cavity 211 is equipped with a gas absorbent 212. When the liquid in the first receiving cavity 110 generates a specific gas, the gas pressure increases, causing the gas to rise. It can pass through the water-resistant and breathable membrane 220 and enter the second receiving cavity 211. The gas absorbent 212 can absorb the specific gas in the gas, thereby reducing the content of the specific gas in the gas and facilitating the retention of the liquid in the first receiving cavity 110.
[0021] In this embodiment, the liquid mainly refers to food liquids or pharmaceutical solvents that emit specific gases.
[0022] In this embodiment, the specific gas includes various gases such as carbon dioxide or oxygen to meet the storage conditions of different drugs. Carbon dioxide is used as an example below.
[0023] In a preferred embodiment, in order to achieve the dual functions of water blocking and air permeability of the water-blocking and air-permeable membrane 220, a plurality of first air vents are provided on the water-blocking and air-permeable membrane 220. The first air vents penetrate the upper and lower end faces of the water-blocking and air-permeable membrane 220, that is, to connect the first receiving cavity 110 and the second receiving cavity 211. Gas can enter the second receiving cavity 211 through the plurality of first air vents. The diameter of the first air vent is between 0.1-10μm, and the diameter of the liquid water droplet is about 100μm. Moreover, there is surface tension on the surface of the liquid water droplet. When it enters the first air vent, since the diameter of the first air vent is much smaller than the diameter of the liquid water droplet, its surface tension will prevent the liquid water droplet from entering the first air vent, thereby achieving "gas-liquid separation" and ensuring that the liquid does not enter the second receiving cavity 211.
[0024] In another preferred embodiment, in order to achieve the dual functions of water blocking and air permeability of the water-blocking and air-permeable membrane 220, the water-blocking and air-permeable membrane 220 is made of polyurethane material. There are a lot of hydrophilic groups in polyurethane, which can adsorb water vapor molecules, release them in the membrane and diffuse them to achieve the air permeability function.
[0025] Of the two methods mentioned above, the method with multiple primary vents has better breathability and waterproofing, but lower overall mechanical strength. The method using polyurethane has moderate breathability but higher mechanical strength. The choice can be made according to actual needs.
[0026] Furthermore, in order to achieve the installation and positioning of the gas absorbent 212, a positioning groove 211a is provided on the side of the second receiving cavity 211. In this embodiment, both the gas absorbent 212 and the second receiving cavity 211 are circular. The positioning groove 211a is arranged in a ring on the inner plug body 210, and a positioning ring 212a is provided on the outer side of the gas absorbent 212. The positioning ring 212a can extend into the positioning groove 211a to achieve the positioning of the gas absorbent 212.
[0027] Furthermore, in order to prevent liquid from entering the second receiving cavity 211 through the gap between the water-blocking and breathable membrane 220 and the inner plug body 210, the water-blocking and breathable membrane 220 is installed onto the inner plug body 210 by ultrasonic welding. Ultrasonic welding can fill the gap between the water-blocking and breathable membrane 220 and the inner plug body 210, ensuring the sealing between the water-blocking and breathable membrane 220 and the inner plug body 210, while also ensuring connection stability.
[0028] After prolonged use, the water-blocking and breathable membrane 220 is prone to blockage, preventing gas from passing through it properly and leading to excessive carbon dioxide accumulation inside the bottle 100. Therefore, in this embodiment, in addition to the gas channel provided by the water-blocking and breathable membrane 220, an air inlet 213 is also provided on the inner stopper body 210. This air inlet 213 connects the first receiving cavity 110 and the second receiving cavity 211, allowing gas from the first receiving cavity 110 to enter the second receiving cavity 211, thus creating an additional gas flow channel. This ensures that at least one channel remains unobstructed, thereby ensuring that carbon dioxide in the gas can be absorbed at all times, thus ensuring the quality of the liquid inside the bottle 100.
[0029] Of course, in this embodiment, in order to increase the gas flow efficiency, the air inlet 213 is set to multiple, specifically six. The six air inlets 213 are arranged at intervals along the circumference of the inner plug body 210. All six air inlets 213 can connect the first receiving cavity 110 and the second receiving cavity 211, which can improve the gas exchange efficiency and also avoid the inability of gas to flow due to blockage of a single air inlet 213.
[0030] Furthermore, the inner plug body 210 is provided with a first sealing part 214 and a second sealing part 215 located at its lower part. The first sealing part 214 is located above the second sealing part 215. The diameter of the first sealing part 214 is larger than the diameter of the second sealing part 215. Multiple air inlets 213 are located on the first sealing part 214. When the first sealing part and the second sealing part 215 are inserted into the opening of the bottle body 100, there is a gap between the second sealing part 215 and the opening of the bottle body 100. The existence of this gap allows the air inlets 213 to communicate with the first receiving cavity 110, thereby allowing the gas in the first receiving cavity 110 to enter the air inlets 213.
[0031] Furthermore, in order to prevent liquid from entering the air intake 213 through this gap, the minimum diameter of the gap should be between 0.1-10μm. Since in this embodiment, the second sealing part 215 is generally frustum-shaped, and the diameter of the bottom end of the second sealing part 215 is smaller than the diameter of its top end, the side of the second sealing part 215 is set as a slope, and the gap between it and the bottle body 100 gradually decreases from bottom to top, so there will be a minimum value for the gap.
[0032] Furthermore, in order to completely seal the bottle body 100, the diameter of the first sealing part 214 is equal to the diameter of the opening of the bottle body 100. When the first sealing part 214 is inserted into the bottle body 100, there is no gap between the outer wall of the first sealing part 214 and the bottle body 100 to avoid air leakage. However, it is also necessary to ensure that the air inlet 213 can communicate with the first receiving cavity 110. Therefore, an air guide groove 214a is provided at the connection between the first sealing part 214 and the second sealing part 215. One end of the air inlet 213 is located in the air guide groove 214a. The air guide groove 214a is used to connect the air inlet 213 with the gap. The presence of the air guide groove 214a allows for partial gas communication and also prevents external gas from entering the bottle body 100.
[0033] Furthermore, in order to achieve communication between the air intake duct 213 and the second receiving cavity 211, the cover is fastened to the inner plug and together with the inner plug body 210 to form a third receiving cavity 216. A plurality of second vent holes 217 are provided on the top of the inner plug body 210. The second vent holes 217 connect the third receiving cavity 216 and the second receiving cavity 211. The air intake duct 213 is connected to the third receiving cavity 216. That is, after the gas in the first receiving cavity 110 enters the air intake duct 213, it is transported by the air intake duct 213 to the third receiving cavity 216, and then transmitted to the second receiving cavity 211 through the second vent holes 217. The gas in the first receiving cavity 110 can smoothly enter the second receiving cavity 211.
[0034] In this embodiment, a bottle body is disclosed, including a bottle body 100 and an inner plug 200. The bottle body 100 has a first receiving cavity 110, and the inner plug is detachably installed at the opening of the bottle body 100. The inner plug 200 includes an inner plug body 210 and a water-resistant and breathable membrane 220 disposed at the bottom of the inner plug body 210. The inner plug body 210 has a second receiving cavity 211 with its opening facing the first receiving cavity 110. The water-resistant and breathable membrane 220 is disposed at the opening of the second receiving cavity 211, and the water-resistant and breathable membrane 220 can separate the first receiving cavity 110 and the second receiving cavity. 211 ensures that no matter which direction the bottle is placed, the liquid in the first receiving cavity 110 cannot enter the second receiving cavity 211. The second receiving cavity 211 is equipped with a gas absorbent 212. When the liquid placed in the first receiving cavity 110 generates carbon dioxide, the gas pressure increases, causing the gas to rise. It can pass through the water-resistant and breathable membrane 220 and enter the second receiving cavity 211. The gas absorbent 212 can absorb the carbon dioxide in the gas, which can reduce the carbon dioxide content in the gas and is beneficial to the retention of the liquid in the first receiving cavity 110.
