Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a split-type salt storage tank with a bottom-mounted desiccant. Background Technology

[0002] Salt is prone to absorbing moisture during use. Although adding anti-caking agents can alleviate this problem, their effectiveness is only during the shelf life of the salt. After consumers open the canned salt, it still easily absorbs moisture and clumps, thus reducing the user experience. To address this moisture problem, those skilled in the art typically consider improving salt storage containers. For example, Chinese Utility Model Patent (Application No. 202120502766.5) discloses a salt desiccant container that facilitates desiccant replacement; Chinese Utility Model Patent (Application No. 202220103938.6) discloses a desiccant lid and a desiccant container with such a lid; and Chinese Utility Model Patent (Application No. CN202020040552.6) discloses a salt desiccant container. However, the above-mentioned technical solutions all involve setting up structural components on the lid or opening of the can for filling with desiccant. The applicant found that when using the above-mentioned salt storage can, the lid needs to be opened and closed frequently to take out salt, and the desiccant on the lid or opening will frequently come into contact with the air outside the can, which will greatly reduce the service life of the desiccant. As a result, consumers need to replace the desiccant frequently. Utility Model Content

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] This embodiment provides a bottom-mounted, split-type salt storage tank. Please refer to [link / reference]. Figures 1 to 4 It includes a tank body 1 and a can lid 2 that can be freely opened and closed and is disposed on the top of the tank body 1; the tank body 1 includes a tank body 3 with open top and bottom, a tank bottom 4, and an isolation component 5;

[0023] The can body 3 is a cylindrical barrel structure. An installation ring 301 is arranged around the inner wall of the lower open end of the can body 3. A limiting protrusion 302 is provided on the top of the installation ring 301 facing inwards. The isolation component 5 includes a breathable cardboard 501 and a grid plate 502. The grid plate 502 is screwed into the installation ring 301 from bottom to top via a threaded connection to hold and fix the breathable cardboard 501 between the grid plate 502 and the limiting protrusion 302. The breathable cardboard 501 has good air permeability, allowing air circulation but preventing salt particles from passing through. The grid plate 502 has densely distributed mesh holes to support the breathable cardboard 501 and prevent it from bending and breaking after carrying salt. The removable sealing cap of the can bottom 4 fits onto the lower open end of the can body 3 and cooperates with the isolation component 5 to form a cavity for containing the desiccant 6.

[0024] Based on the above structure, the method of using this utility model is as follows: First, detach the bottom 4 from the lower open end of the body 3. Then, place the desiccant 6 in the groove on the upper surface of the bottom 4. Since the isolation component 5 is fixedly installed in the ring of the mounting ring 301 through the grid plate 502, the salt will be supported on the breathable cardboard 501 and supported by the grid plate 502. Therefore, the salt stored in the salt storage tank will not spill from the lower end of the body 3. Then, seal the bottom 4 holding the desiccant to the lower open end of the body 3. At this time, the desiccant is sealed and contained in the cavity formed by the bottom 4, the lower open end of the body 3, and the isolation component 5. This can dehydrate and dry the salt stored in the salt storage tank to prevent the salt from absorbing moisture and clumping. Based on the above, since the desiccant is always placed at the bottom of the salt storage tank, the desiccant only comes into contact with the air inside the salt storage tank. When taking out the salt, the desiccant will not be spilled. Contact with the air outside the tank not only extends the shelf life of the desiccant but also ensures its dehydration and drying effect. Simultaneously, since the tank bottom 4 is detachably located at the lower open end of the tank body 3, and due to the function of the isolation component 5, the tank bottom 4 can be removed at any time during use to facilitate convenient and flexible replacement of the desiccant without affecting the storage of salt inside the tank. Furthermore, to ensure the permeability of the breathable cardboard 501, it can be easily replaced after prolonged use. Specifically, the tank containing salt can be inverted, or after the salt has been used up, the tank bottom 4, the grid plate 502, and the breathable cardboard 501 can be removed in sequence to replace the cardboard 501. This invention can be used directly as packaging for salt after it leaves the factory, or as a condiment container for storing salt and other seasonings.

[0025] To facilitate the rotation and removal of the grating plate 502, further, in a preferred embodiment, please refer to... Figure 1 , Figure 3 and Figure 4 The bottom of the grid plate 502 is provided with a pinch handle 503.

[0026] To improve the sealing effect between the bottom 4 and the body 3, further, in a preferred embodiment, please refer to... Figure 1 and Figure 2 A sealing strip 7 is affixed to the outer circumferential joint where the bottom 4 of the can and the body 3 are sealed together. When it is necessary to remove the bottom 4 of the can to fill or replace the desiccant, the sealing strip 7 can be torn off at any time and then replaced with a new sealing strip 7 for re-application.

[0027] To facilitate the installation and removal of the tank bottom 4, further, in a preferred embodiment, please refer to... Figure 1 , Figure 3 and Figure 4The bottom of the can 4 is provided with an external thread on its periphery, and the lower open end of the can body 3 is provided with an internal thread that mates with the external thread, so that the bottom of the can 4 is sealed and covered by the lower open end of the can body 3 through a threaded connection.

[0028] To improve the sealing effect between the bottom 4 and the body 3, further, in a preferred embodiment, please refer to... Figure 1 , Figure 3 and Figure 4 The tank body 1 also includes a sealing gasket 8. When the tank bottom 4 is sealed and closed at the lower open end of the tank body 3, the sealing gasket 8 is clamped and fixed between the bottom of the mounting ring 301 and the top of the tank bottom 4.

[0029] Furthermore, in a preferred embodiment, please refer to Figure 1 as well as Figures 3-5 The salt storage tank of this utility model also includes an airtight, elastic rubber cover 11, which is sealed to the upper port of the tank bottom 4 to form a spacer cavity 9. The bottom of the tank bottom 4 is provided with an inflation nozzle 10 that communicates with the spacer cavity 9. Based on this structure, gas can be injected into the spacer cavity 9 through the inflation nozzle 10 to expand the spacer cavity 9. This allows residual air in the cavity formed by the tank bottom 4, the lower opening of the tank body 3, and the isolation component 5 after the desiccant is placed to be discharged, thereby improving the service life of the desiccant. In order to facilitate the discharge of residual air, the above inflation operation should be carried out before the tank bottom 4 is completely tightened and sealed. After the inflation operation is completed, the tank bottom 4 can be tightened and sealed.

[0030] Furthermore, in a preferred embodiment, the salt storage tank is one of an aluminum tank, an iron tank, or a plastic tank.
