[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is specifically described in the following embodiments in conjunction with the accompanying drawings.

[0026] Example

[0027] Figure 1 This is a schematic diagram of the structure of a screw-type storage tank. Figure 2 This is an exploded view of a screw-on storage tank. Figure 3 It is a schematic diagram of the structure of the tank body in the screw-type storage tank. Figure 4 It is a schematic diagram of the structure of the inner cover in a screw-type storage tank. Figure 5 It is a schematic diagram of the structure of the top cover in the screw-type storage tank. Figure 6 It is a schematic diagram of the structure of the outer cover in a screw-type storage tank.

[0028] like Figures 1 to 6 As shown, this embodiment provides a screw-on storage tank, comprising: a tank body 10 , an inner cover 20 , a top cover 30 and an outer cover 40 .

[0029] like Figure 1 , Figure 2 as well as Figure 3 As shown, the tank body 10 comprises a tank body section 11 and a tank mouth section 12. The tank body section 11 has an inner cavity 13 for storing articles, the diameter of the tank body section 11 is larger than the diameter of the tank mouth section 12, and an external thread locking portion 14 is provided on the outer wall of the tank mouth section 12.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, a clamping block 15 is provided on the top of the tank body section 11. Since the diameter of the tank body section 11 is larger than the diameter of the tank mouth section 12, a circular platform is formed on the top of the tank body section 11, and the clamping block 15 is located on the platform.

[0031] like Figure 2 and Figure 3As shown, in this embodiment, the clamping block 15 is a quasi-isosceles trapezoidal block. The upper base of the clamping block 15 faces the inner wall of the locking section 21, and the lower base of the clamping block 15 fits against the outer wall of the can mouth section 12. And, in this embodiment, the number of clamping blocks 15 is preferably set to two.

[0032] As Figure 1 , Figure 2 and Figure 4 shown, the inner lid 20 includes a locking section 21 and a clamping section 22. The outer diameter of the locking section 21 is equal to the diameter of the can body section 11, and the inner diameter is equal to the diameter of the can mouth section 12. An internal thread locking portion 23 that can be locked with the external thread locking portion 14 is provided on the inner wall of the locking section 21. A plurality of arc-shaped holes 24 are formed in the outer wall of the clamping section 22 and near the top. A plurality of connection openings 25 are further provided on the outer wall of the clamping section 22. The upper end of each connection opening 25 is located on the top surface of the clamping section 22, and the lower end is communicated with an arc-shaped hole 24. An annular protrusion 26 is provided on the outer wall of the clamping section 22 and near the bottom end.

[0033] As Figure 2 and Figure 4 shown, in this embodiment, each arc-shaped hole 24 is streamline-shaped, and each arc-shaped hole 24 is arranged circumferentially on the outer wall of the clamping section 22. Semi-circular protrusions 241 for clamping the sliding block 32 are respectively provided at both ends of the arc-shaped hole 24. Among them, because semi-circular protrusions 241 for limiting the sliding block 32 are provided at both the upper end and the lower end of the arc-shaped hole 24, the sliding block 32 will not automatically fall when sliding to the upper end of the arc-shaped hole 24, nor will the outer lid 40 be easily toggled, enabling the top lid 30 to rotate and rise, thus ensuring the stability of the present utility model during use.

[0034] As Figure 2 and Figure 4 shown, in this embodiment, the connection opening 25 is a notch starting from the top end of the clamping section 22 and opening downward through the circumferential wall of the clamping section 22.

[0035] In this embodiment, the number of arc-shaped holes 24 is preferably set to two, so the number of connection openings 25 is also preferably set to two.

[0036] As Figure 4 shown, in this embodiment, a limiting post 27 and an arched limiting block 28 for limiting the clamping block 15 are provided on the inner wall of the locking section 21 near the bottom end. Among them, the limiting block 28 is a limiting block 28 that can undergo elastic deformation.

[0037] As Figure 1 , Figure 2 , and Figure 5As shown, the top cover 30 is in the shape of a round cup. The outer diameter of the top cover 30 is equal to the inner diameter of the inner cover 20, and the opening of the top cover 30 faces the inner cover 20. A discharge port 31 is formed on the outer wall of the top cover 30. A plurality of sliders 32 are provided on the outer wall of the top cover 30, and each slider 32 can be slidably connected to an arc-shaped hole 24 through a connection opening 25.

[0038] In this embodiment, the number of sliders 32 provided on the outer wall of the top cover 30 is limited to two.

[0039] As Figure 1 , Figure 2 , and Figure 6 As shown, the outer cover 40 is in the shape of a cylindrical ring. The outer diameter of the outer cover 40 is equal to the diameter of the locking section 21, and the inner diameter is equal to the diameter of the engaging section 22. An annular groove 41 that can be engaged with the annular protrusion 26 is provided on the inner wall of the outer cover 40. A plurality of limiting grooves 42 arranged axially are further provided on the inner wall of the outer cover 40. Each limiting groove 42 is located on the same generatrix as a connection opening 25, and each limiting groove 42 is slidably connected to a slider 32.

[0040] As Figure 2 and Figure 6 As shown, in this embodiment, a fitting portion 43 is provided at the top end of the outer cover 40, and the inner diameter of the fitting portion 43 is equal to the outer diameter of the top cover 30.

[0041] In this embodiment, since the annular groove 41 of the outer cover 40 can be rotationally engaged with the annular protrusion 26 on the inner cover 20, the outer cover 40 can be rotatably provided on the inner cover 20.

[0042] In this embodiment, two limiting grooves 42 are preferably provided on the inner wall of the outer cover 40.

[0043] In this embodiment, when the top cover 30 does not rotate and rise, the upper end surface of the outer cover 40 and the upper end surface of the top cover 30 are on the same horizontal plane, so that the discharge port 31 on the top cover 30 is blocked by the inner cover 20. After the top cover 30 rotates and rises, the discharge port 31 on the top cover 30 will be exposed.

[0044] The assembly and use process of a twist-type storage tank of the present utility model is as follows:

[0045] First, the inner cover 20 is installed on the tank body 10 by cooperating with the external thread locking portion 14 on the tank mouth section 12 and the internal thread locking portion 23 on the locking section 21. During this installation process, the block 15 on the top of the tank body section 11 will contact the stop block 28 on the inner wall of the locking section 21 as the inner cover 20 rotates and falls. At this time, because the stop block 28 is arched and elastically deformable, and the upper bottom of the block 15 faces the inner wall of the locking section 21, as the inner cover 20 continues to rotate and fall, the block 15 will gradually press the stop block 28 and finally pass over the stop block 28, so that the block 15 is located between the stop block 28 and the stop column 27, thereby achieving the effect of limiting.

[0046] Next, the top cover 30 enters the arc-shaped hole 24 from the connection opening 25 on the engaging section 22 through the slider 32 on the outer wall, so that the top cover 30 is installed inside the inner cover 20. Because the slider 32 on the outer wall of the top cover 30 is slidably connected with the arc-shaped hole 24 on the engaging section 22, the top cover 30 can rotate along the arc-shaped hole 24 inside the inner cover 20 and move upward at the same time.

[0047] Finally, the outer cover 40 is rotatably mounted on the inner cover 20 through the cooperation between the annular groove 41 on the outer cover 40 and the annular protrusion 26 on the locking section 21. At the same time, each limiting groove 42 on the inner wall of the outer cover 40 has a slider 32 on the outer wall of the top cover 30, and is slidably connected to the slider 32.

[0048] When taking out the items in the storage tank, the outer cover 40 only needs to be rotated in the positive direction. The limit groove 42 on the inner wall of the outer cover 40 will drive the slider 32 on the top cover 30 to rotate, and the arc hole 24 will also limit the slider 32, so that the slider 32 will move upward while rotating until the slider 32 moves to the upper end of the arc hole 24 and stops. At this time, the discharge port 31 on the top cover 30 is exposed after the top cover 30 rotates and rises, so that the items in the storage tank can be taken out from the discharge port 31 in an inverted or tilted manner. When the material is taken out, the outer cover 40 is rotated in the opposite direction again. At this time, the slider 32 will rotate and descend under the restriction of the limit groove 42 and the arc hole 24, so that the discharge port 31 on the top cover 30 is blocked by the inner cover 20.

[0049] Functions and Effects of the Embodiments

[0050] According to the screw-type storage tank involved in the present utility model, since the annular protrusion provided on the inner cover can be engaged with the annular groove on the outer cover, the outer cover can be rotatably arranged on the inner cover. And because the slider on the top cover is simultaneously slidably located in the arc-shaped hole on the outer wall of the inner cover and the limiting groove arranged axially on the inner wall of the outer cover, when the outer cover is rotated, the top cover will rise or fall. Therefore, the items in the storage tank can be taken out from the discharge port on the top cover, so that the items in the storage tank can be reduced from contacting with the air, and the situation of the items in the storage tank becoming stale or deteriorating can be largely prevented, avoiding waste.

[0051] The above embodiments are preferred cases of the present utility model and are not used to limit the protection scope of the present utility model.
