[0028] 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.

[0029] like Figures 1-8 As shown, this utility model discloses a reusable silicone food storage bag, including a bag body 1 extending vertically along its length. The bag body 1 has a receiving cavity 11 inside. The bag body 1 is made of silicone and includes an opening 12 above the receiving cavity 11, and front connecting sections 2 and rear connecting sections 3 located on the front and rear sides of the opening 12. The front connecting sections 2 and rear connecting sections 3 are detachably connected by magnetic attraction, fastening, or other means. An exhaust column 4 and a matching cover 5 are installed on the front side of the bag body 1. The exhaust column 4 has an exhaust hole 41 communicating with the receiving cavity 11. The matching cover 5 and the exhaust column 4 are connected by screws. The bag can be detachably connected by means of a plug, etc. The projection of the vent 41 facing forward falls on the vent column 4. 1. Since the bag body 1 is made of silicone, silicone material has good flexibility and elasticity, is not easily damaged or torn, and has a long service life. This means that silicone food storage bags can withstand more usage cycles and are suitable for long-term repeated use. Repeated use can reduce the demand for disposable plastic products and help reduce plastic waste. At the same time, silicone is considered a very safe material, non-toxic and odorless, and will not release harmful chemical substances into food. Silicone can maintain its physical properties over a wide temperature range, and is resistant to both high and low temperatures. Even at high temperatures, it will not react with food, ensuring food safety and original flavor. This makes silicone food storage bags safe to use not only in refrigerators but also in microwave ovens and dishwashers, increasing their convenience and versatility. 2. Because the front connecting section 2 and the rear connecting section 3 are detachably connected, separating them allows opening the top of the bag body 1 through the opening 12 for taking items in and out. Connecting the front connecting section 2 and the rear connecting section 3 ensures that the items are stably positioned within the receiving cavity 11 of the bag body 1, thus facilitating the movement of the bag body 1. 3. Due to the presence of the fitting cover 5 and the exhaust column 4 on the front side of the bag body 1, after the items to be placed in the containing cavity 11 are put into the bag body 1, the fitting cover 5 can be removed from the exhaust column 4, and the gas in the containing cavity 11 can be squeezed through the exhaust column 4 to enter the outside. Then the fitting cover 5 is put back in, so that most of the gas in the bag body 1 is discharged, reducing the chance of food coming into contact with oxygen, and reducing the occurrence of food dehydration and drying or becoming damp and soft due to moisture absorption. In addition, expelling the air in the preservation bag can make the bag more compact and easier to store.

[0030] The front connecting section 2 is provided with a sealing plug 21 protruding rearward, and the rear connecting section 3 is provided with a sealing slot 31 corresponding to the sealing plug 21. After food is placed into the accommodating cavity 11, the sealing plug 21 enters the sealing slot 31 when the front connecting section 2 and the rear connecting section 3 are connected together. Therefore, in addition to the gas in the accommodating cavity 11 being exhausted through the exhaust column 4, the gas from outside is blocked by the sealing plug 21 when entering the accommodating cavity 11 after the food is placed into the accommodating cavity 11. If the gas in the accommodating cavity 11 moves upward, it cannot pass the sealing plug 21, thereby improving the sealing performance of the accommodating cavity 11 of the bag body 1.

[0031] Preferably, the rear connecting section 3 is provided with a plurality of connecting plugs 32 protruding forward, and the front connecting section 2 is provided with a connecting slot 22 corresponding to each connecting plug 32. Each connecting plug 32 is provided with an engaging slot 321 recessed inward, and each engaging slot 321 is annular. The front connecting section 2 is provided with an engaging plug 23 in each connecting slot 22. When the front connecting section 2 and the rear connecting section 3 are connected together, i.e., the top of the bag body 1 is sealed, the part of each engaging plug 421 in front of the engaging slot 321 enters the corresponding connecting slot 22 first. This part of the engaging plug 421 forcibly passes the corresponding engaging plug 23, thereby completing the installation of each engaging plug 23 and the engaging slot 321, so that each connecting plug 32 is stably positioned in the corresponding connecting slot 22, and the front connecting section 2 and the rear connecting section 3 are stably connected together. When the bag body 1 needs to be opened, i.e., the front connecting section 2 and the rear connecting section 3 are separated, and the object in the accommodating cavity 11 is taken out, the rear connecting section 3 is subjected to a rearward force, thereby driving each connecting plug 32 rearward. The part of each connecting plug 32 in front of the corresponding engaging slot 321 forcibly passes the corresponding engaging plug 23, thereby separating each connecting plug 32 and the corresponding connecting slot 22, and separating the front connecting section 2 and the rear connecting section 3. Therefore, the top of the bag body 1 is opened, and the object in the accommodating cavity 11 can be taken out.

[0032] Preferably, the exhaust hole 41 penetrates the exhaust column 4, and the exhaust column 4 comprises, from front to back, the mounting section 42, the loading section 43 and the limiting section 44, the bag body 1 is provided with a loading groove 13 corresponding to the insertion section, the limiting section 44 is located in the containing cavity 11 and has a diameter larger than the loading groove 13, the limiting section 44 is threadedly connected with the loading section 43. Since the exhaust column 4 comprises the limiting section 44 with a diameter larger than the loading groove 13, during the process of loading the exhaust column 4 into the bag body 1, after the mounting section 42 is inserted into the loading groove 13, the limiting section 44 is then loaded through the containing cavity 11 to be located behind the mounting section 42 and fixed with the bag body 1, and then the loading section 43 is rotated to complete the connection with the limiting section 44, so that the relative position of the exhaust column 4 and the bag body 1 is determined.

[0033] Preferably, the bag body 1 protrudes a plurality of limiting columns 14 in the containing cavity 11, each limiting column 14 is spaced apart along the circumference of the limiting disc, and each limiting column 14 is inserted into the bag body 1. Since each limiting column 14 exists, after the limiting section 44 is located in the containing cavity 11, each limiting column 14 is inserted into the limiting section 44, so that the relative position of the bag body 1 and the limiting section 44 is determined without external force. At this time, the limiting section 44 cannot be rotated compared to the loading section 43. When it is necessary to remove the exhaust column 4 from the bag body 1, the loading section 43 is rotated to separate the loading section 43 from the limiting section 44 by moving the limiting section 44 rearward to separate the limiting columns 14 from the limiting section 44, so that the limiting section 44 is removed.

[0034] Preferably, the mounting section 42 is circumferentially fixedly mounted with a plurality of mounting plugs 421, and the matching cover 5 is made of a material that is easy to deform, such as rubber, and is provided with a mounting slot 51 corresponding to each mounting plug 421. Therefore, after the gas in the bag body 1 is exhausted, the matching cover 5 is loaded onto the mounting section 42, that is, each mounting plug 421 is inserted into the corresponding mounting slot 51, and then the matching cover 5 is stably positioned on the mounting section 42 to block the front side of the exhaust hole 41, so that the gas exchange between the containing cavity 11 and the outside cannot be achieved through the exhaust hole 41.

[0035] Preferably, each mounting plug 421 is provided in a ladder shape with a narrow outer side and a wide inner side. Since each mounting plug 421 is provided in a ladder shape with a wide inner end surface and a narrow outer end surface, during the process of loading the limiting disc into the mounting section 42, the outer side of each mounting plug 421, that is, the part with a smaller width than the inner side, will first enter the corresponding mounting slot 51 to facilitate the cooperation between each mounting plug 421 and the corresponding mounting slot 51, and the matching cover 5 can be stably positioned on the mounting section 42 without external force.

[0036] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
