Description

Technical Field

[0001] This utility model relates to the technical field of Mason jar lids, specifically a Mason jar lid that facilitates vacuuming. Background Technology

[0002] Mason jars were invented in the 19th century, a time when refrigerators were not yet widespread and preservatives were not commonly used. Food storage and pickling were problems that plagued housewives. Due to their excellent airtightness, Mason jars could be used to store dry or pickled foods, extending their freshness and meeting the food storage needs of the time, thus gaining widespread popularity.

[0003] Existing Mason jars achieve a seal by rotating a threaded cap, which provides some sealing but makes it difficult to expel air from inside. For foods requiring long-term storage or those demanding a vacuum environment, this sealing method is insufficient. Therefore, a lid capable of effectively creating a vacuum is needed to improve sealing performance. Utility Model Content

[0004] The purpose of this invention is to provide a Mason jar lid that facilitates vacuum sealing, solving the problem that existing Mason jars achieve sealing through rotating threaded caps, which, while providing a certain sealing effect, are inconvenient for venting air from the jar. For foods requiring long-term storage or demanding vacuum conditions, this sealing method is insufficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Mason jar lid that facilitates vacuuming, comprising a lid body, an installation groove formed in the center of the top of the lid body, a sealing groove formed in the installation groove, a through hole formed in the center of the lid body, a sealing silicone sealant provided in the installation groove, a plastic sealing plate fixedly connected to the top of the installation groove, and the plastic sealing plate fixedly connected to the lid body, and an air extraction hole formed in the center of the plastic sealing plate.

[0006] By adopting the above technical solution, during vacuuming, the sealing silicone is driven upward by suction, creating a gap with the through hole in the middle of the lid, allowing the air inside the Mason jar to be drawn away. When the vacuuming ends and the Mason jar is in a negative pressure state, the sealing silicone is pressed tightly onto the through hole in the lid by atmospheric pressure, which can more effectively maintain the seal inside the Mason jar.

[0007] As a further description of the above technical solution: an exhaust assembly can also be provided in the mounting groove. The exhaust assembly includes a silicone umbrella pin, which is disposed in the mounting groove. A second exhaust column is fixedly connected to the top of the silicone umbrella pin, a sealing element is fixedly connected to the bottom of the silicone umbrella pin, and a connecting column is fixedly connected to the middle of the bottom of the silicone umbrella pin. The connecting column passes through and is disposed in the through hole of the cover body, and a limit sleeve is fixedly connected to the bottom of the connecting column.

[0008] By adopting the above technical solution, during vacuuming, the silicone umbrella pin is driven upward by suction, creating a gap with the through hole in the middle of the lid, allowing the air inside the Mason jar to be drawn away. When the vacuuming ends and the Mason jar is under negative pressure, the silicone umbrella pin is pressed tightly against the through hole in the lid by atmospheric pressure, and the bottom of the silicone umbrella pin fits into the sealing groove in the mounting groove of the sealing element, so as to more effectively maintain the seal inside the Mason jar.

[0009] As a further description of the above technical solution: the through hole of the cover body communicates with the mounting groove.

[0010] By adopting the above technical solution, it is convenient for the air inside the can to be discharged outside the lid.

[0011] As a further description of the above technical solution: the bottom of the sealing silicone fits into the sealing groove.

[0012] By adopting the above technical solution, in order to facilitate the end of vacuuming, when the Mason jar is in a negative pressure state, the sealing silicone is pressed tightly onto the through hole of the lid by atmospheric pressure, ensuring the sealing effect of the sealing silicone.

[0013] As a further description of the above technical solution: a first exhaust column is provided in the air extraction hole, and the bottom of the first exhaust column is fixedly connected to the sealing silicone.

[0014] By adopting the above technical solution, the first vent column exposed outside the cover by the sealing silicone is pulled upward, causing the sealing silicone to detach from the through hole of the cover, allowing air to enter the tank for depressurization.

[0015] As a further description of the above technical solution: a sealing ring is fixedly connected to the bottom of the cover, and the sealing ring is used to seal the Mason jar by negative pressure during vacuuming.

[0016] By adopting the above technical solution, the lid is installed on the Mason jar, and the sealing ring inside the lid will contact the mouth of the Mason jar to form a seal.

[0017] As a further description of the above technical solution: the sealing element fits into the sealing groove.

[0018] By adopting the above technical solution, the sealing element is convex and the sealing groove is concave, ensuring the sealing effect of the silicone umbrella pin.

[0019] As a further description of the above technical solution: four evenly distributed limiting blocks are fixedly connected to the top of the limiting sleeve, and the limiting blocks are set on the outside of the connecting column.

[0020] By adopting the above technical solution, the four limiting blocks can prevent the bottom limiting sleeve from blocking the through hole of the cover when the silicone umbrella rises.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a Mason jar lid that facilitates vacuuming. During vacuuming, the sealing silicone or silicone umbrella pin is pulled upward by suction, creating a gap with the through hole in the middle of the lid body, allowing air inside the Mason jar to be drawn out. When the vacuuming ends and the Mason jar is under negative pressure, the sealing silicone or silicone umbrella pin is pressed tightly onto the through hole of the lid body by atmospheric pressure. Furthermore, the sealing silicone fits into the sealing groove, and the bottom of the silicone umbrella pin fits into the sealing groove in the installation groove, thus more effectively maintaining the seal inside the Mason jar.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0026] Example 1: Reference Figure 1 , Figure 2 and Figure 4This utility model discloses a Mason jar lid for easy vacuuming, comprising a lid body 1. A mounting groove 2 is formed in the center of the top of the lid body 1, facilitating the installation of a sealing silicone 5. A sealing groove 3 is formed within the mounting groove 2. A through-hole 4 is formed in the center of the lid body 1, allowing air to enter or exit. The sealing silicone 5 is placed within the mounting groove 2, effectively sealing the through-hole 4. A plastic sealing plate 7 is fixedly connected to the top of the mounting groove 2. Four top blocks (not shown in the figure) are installed on the inner side of the plastic sealing plate 7 to prevent the sealing silicone 5 from blocking the vent hole 8 when it moves upward. The plastic sealing plate 7 is fixedly connected to the lid body 1, and the vent hole 8 is formed in the center of the plastic sealing plate 7, facilitating air exit. A threaded groove 9 is formed on the inner wall of the lid body 1, facilitating threaded connection with the outside of the Mason jar opening. The through-hole 4 communicates with the mounting groove 2, allowing air inside the jar to exit the lid body 1. The bottom of the sealing silicone 5 fits into the sealing groove 3. To facilitate the completion of vacuuming, when the Mason jar is under negative pressure, the sealing silicone 5 is pressed tightly against the through hole 4 of the lid by atmospheric pressure, ensuring the sealing effect of the sealing silicone 5. A first exhaust column 6 is provided in the vent hole 8, and the bottom of the first exhaust column 6 is fixedly connected to the sealing silicone 5. By pulling the first exhaust column 6, which is exposed outside the lid 1, upward, the sealing silicone 5 is disengaged from the through hole 4 of the lid, allowing air to enter the jar for depressurization. The diameter of the first exhaust column 6 is smaller than the diameter of the vent hole 8, facilitating the expulsion of air. A sealing ring 10 is fixedly connected to the upper part of the inner wall of the lid 1, and the sealing ring 10 is located outside the through hole 4 of the lid. When the lid 1 is installed on the Mason jar, the sealing ring 10 inside the lid 1 will contact the mouth of the Mason jar to form a seal. The lid 1 is threaded to the mouth of the Mason jar through the threaded groove 9 on the inner wall. During the tightening process, the sealing ring 10 on the upper part of the inner wall of the lid 1 will fit tightly against the mouth of the jar, thereby forming a double-protection sealing effect to prevent external air from easily entering the jar.

[0027] Example 2: Reference Figure 3This utility model discloses a Mason jar lid for easy vacuuming, comprising a lid body 1, an installation groove 2 formed in the center of the top of the lid body 1, a sealing groove 3 formed within the installation groove 2, a through hole 4 extending through the center of the lid body 1, and a threaded groove 9 on the inner wall of the lid body 1. An exhaust assembly can also be disposed within the installation groove 2. The exhaust assembly includes a silicone umbrella pin 11 disposed within the installation groove 2, a second exhaust column 12 fixedly connected to the top of the silicone umbrella pin 11, a sealing element 13 fixedly connected to the bottom of the silicone umbrella pin 11, and a connecting column 14 fixedly connected to the center of the bottom of the silicone umbrella pin 11. The connecting column 14 extends through and is disposed within the through hole 4 of the lid body, and the diameter of the connecting column 14 is smaller than the diameter of the through hole 4 of the lid body to facilitate air exhaust. A limiting sleeve 15 is fixedly connected to the bottom of the connecting column 14, the sealing element 13 fits into the sealing groove 3, and four evenly distributed limiting blocks 16 are fixedly connected to the top of the limiting sleeve 15, with the limiting blocks 16 positioned outside the connecting column 14. If the mounting groove 2 is equipped with a silicone umbrella pin 11, during vacuuming, the silicone umbrella pin 11 is driven upward by suction. At the same time, the silicone umbrella pin 11 drives the bottom connecting post 14 and the limiting sleeve 15 to move upward until the limiting block 16 at the top of the limiting sleeve 15 contacts the inner wall of the cover 1. At this time, a gap is formed between the silicone umbrella pin 11 and the cover through hole 4 in the middle of the cover 1, so that the air inside the Mason jar can be drawn away. When the vacuuming ends and the Mason jar is in a negative pressure state, the silicone umbrella pin 11 is pressed tightly onto the cover through hole 4 by atmospheric pressure. Furthermore, the bottom of the silicone umbrella pin 11 fits with the sealing groove 3 in the mounting groove 2 through the sealing element 13, so as to more effectively maintain the seal inside the Mason jar.

[0028] Example 3: Reference Figure 5 The sealing state of the Mason jar lid that facilitates vacuuming according to this utility model can also be in the following form: a sealing ring 10 is fixedly connected to the upper part of the inner wall of the lid body 1, and the sealing ring 10 is set outside the through hole 4 of the lid body. When the lid body 1 is installed on the Mason jar, the sealing ring 10 inside the lid body 1 will contact the mouth of the Mason jar. When the vacuuming is finished and the Mason jar is in a negative pressure state, a seal is formed under compression.

[0029] Example 4: Reference Figure 6 The sealing state of the Mason jar lid that facilitates vacuuming according to this utility model can also be in the following form: the inner wall of the lid body 1 is provided with a threaded groove 9. The threaded groove 9 on the inner periphery of the lid body 1 matches the thread on the mouth of the Mason jar. Therefore, the lid body 1 can be screwed onto the jar by the thread, so that the mouth of the Mason jar and the inside of the lid body 1 are tightly fitted, thereby forming an overall seal.

[0030] Working Principle: In use, the inner circumference of the lid 1 has a threaded groove 9 that matches the thread on the mouth of the Mason jar. Therefore, the lid 1 can be screwed onto the jar, creating a tight fit between the jar mouth and the inside of the lid 1, forming a complete seal. Alternatively, a sealing ring 10 is attached to the inside of the lid 1. Placing the lid 1 on the mouth of the Mason jar allows the sealing ring 10 inside the lid 1 to contact the jar mouth, thus forming a preliminary seal between the jar and the lid. Another option is to connect the lid 1 to the mouth of the Mason jar via the threaded groove 9 on its inner wall. During tightening, the sealing ring 10 on the upper part of the inner wall of the lid 1 will tightly adhere to the jar mouth, creating a double-layered seal to prevent external air from easily entering the jar, laying the foundation for subsequent vacuuming operations. When vacuuming is required, align and connect the interface of the vacuum equipment to the top of the lid 1. After the vacuum equipment is started, the sealing silicone 5 or silicone umbrella pin 11 is pulled upward by suction, creating a gap between it and the through hole 4 in the middle of the lid 1. Air inside the can is then extracted sequentially through the through hole 4, the gap between the sealing silicone 5 or silicone umbrella pin 11 and the mounting groove 2, and the vent 8. When the vacuuming ends and the Mason jar is under negative pressure, the sealing silicone 5 or silicone umbrella pin 11 is pressed tightly against the through hole 4 by atmospheric pressure, and its bottom fits tightly against the sealing groove 3. This effectively maintains the seal inside the Mason jar. When it is necessary to depressurize the Mason jar and open the lid, the first venting column 6 at the top of the sealing silicone 5 or the second venting column 12 at the top of the silicone umbrella pin 11 can be pulled upwards, causing the sealing silicone 5 or silicone umbrella pin 11 to disengage from the through hole 4, allowing air to enter the can for depressurization, thus facilitating the unscrewing of the lid from the can.
