[0049] Refer to the attached drawings of the specification of this utility model Figures 1 to 10In the following description, a double-layer container with a detachable liner according to a preferred embodiment of the utility model will be disclosed and explained, wherein the double-layer container includes an outer shell 10, an inner shell 20 and a cover body 30, the inner shell 20 is detachably embedded in the outer shell 10 from top to bottom, and the cover body 30 is detachably installed on the outer shell 10. For example, the cover body 30 can be provided with an internal thread structure, and the top of the outer shell 10 is provided with an external thread structure. The internal thread structure of the cover body 30 and the external thread structure of the outer shell 10 cooperate with each other, so that the cover body 30 can be detachably installed on the outer shell 10.

[0050] When the cover 30 is mounted on the outer shell 10, the cover 30 closes the opening of the inner liner 20, so that the user can carry the double-layer container. When the cover 30 is removed from the outer shell 10, the opening of the inner liner 20 is exposed, and the user is allowed to take out the substance contained in the inner liner 20, such as cream. In addition, after the cover 30 is removed from the outer shell 10, the inner liner 20 is allowed to be separated from the outer shell 10 to be replaced with a new one. For example, when the cream contained in the inner liner 20 is used up, the user can replace the new one. In this way, the outer shell 10 and the cover 30 can be reused to reduce the user's use cost and reduce waste.

[0051] In order to facilitate the separation of the inner liner 20 from the outer shell 10, the double-layer container of the present invention further includes a repulsion unit 40, which is configured to push the inner liner 20 upward so that the inner liner 20 moves upward relative to the outer shell 10. Specifically, after the cover 30 is separated from the outer shell 10, the outer shell 10 and the cover 30 no longer clamp the inner liner 20. At this time, the repulsion unit 40 can push the inner liner 20 upward so that the top of the inner liner 20 is away from the top of the outer shell 10, that is, the top of the inner liner 220 can be exposed to the outside of the outer shell 10, so that the user can pinch the opposite sides of the top of the inner liner 20 with fingers to conveniently take out the inner liner 20.

[0052] Specifically, refer to the attached Figures 2 to 5The repulsion unit 40 includes at least one first magnet 41 and at least one second magnet 42, wherein the first magnet 41 is arranged on the outer shell 10, and the second magnet 42 is arranged on the inner liner 20, wherein after the inner liner 20 is embedded in the outer shell 10 from top to bottom, the position of the first magnet 41 and the position of the second magnet 42 correspond to each other in the height direction, and the magnetic pole of the first magnet 41 facing the second magnet 42 and the magnetic pole of the second magnet 42 facing the first magnet 41 are the same. For example, if the top of the first magnet 41 is the N pole, the bottom of the second magnet 42 is the N pole, and if the top of the first magnet 41 is the S pole, the bottom of the second magnet 42 is the S pole. In this way, based on the principle that like poles repel each other and opposite poles attract each other, after the cover body 30 is separated from the outer shell 10, the repulsive force generated between the first magnet 41 and the second magnet 42 can push the inner liner 20 upward and make the top of the inner liner 20 away from the top of the outer shell 10.

[0053] In the attached Figures 1 to 10 In this specific example of the double-layer container of the utility model shown, the first magnet 41 is arranged at the bottom of the outer shell 10, and the second magnet 42 is arranged at the top of the inner liner 20, so that after the inner liner 20 is embedded in the outer shell 10 from top to bottom, the top of the first magnet 41 and the bottom of the second magnet 42 are adjacent, that is, the top of the first magnet 41 and the bottom of the second magnet 42 have a small distance, so that the first magnet 41 and the second magnet 42 generate a repulsive force sufficient to push the inner liner 20 upward.

[0054] It is worth mentioning that the specific manner of arranging the first magnet 41 at the bottom of the shell 10 and the second magnet 42 at the bottom of the liner 20 is not limited in the double-layer container of the present invention. Figures 1 to 10 In the specific example of the double-layer container of the present invention shown, the bottom of the outer shell 10 has an outer shell embedding groove 11, and the first magnet 41 is embedded in the outer shell embedding groove 11 of the outer shell 10, so that the first magnet 41 is arranged on the outer shell 10, and the bottom of the inner liner 20 has an inner liner embedding groove 21, and the second magnet 42 is embedded in the inner liner embedding groove 21 of the inner liner 20, so that the second magnet 42 is arranged on the inner liner 20. Optionally, in other examples of the double-layer container of the present invention, the first magnet 41 can be glued to the bottom of the outer shell 10 using glue, and the second magnet 42 can be glued to the bottom of the inner liner 20 using glue.

[0055] Continue to refer to the attached Figures 2 to 10The outer shell 10 has at least one slide groove 12, at least one guide groove 13 and at least one locking groove 14. The slide groove 12 extends downward from a top edge 15 of the outer shell 10. In the circumferential direction, the slide groove 12 and the locking groove 14 are adjacent, and the guide groove 13 is connected to the locking groove 14 at the bottom of the slide groove 12. The outer wall of the inner liner 20 has at least one locking protrusion 22. In the process of embedding the inner liner 20 in the outer shell 10, the locking protrusion 22 of the inner liner 20 is allowed to move downward along the slide groove 12 of the outer shell 10. When the locking protrusion 22 of the inner liner 20 slides along the slide groove 12 of the outer shell 10 to a position corresponding to the guide groove 13, by rotating the inner liner 20, the locking protrusion 22 of the inner liner 20 can slide to the locking groove 14 through the guide groove 13 of the outer shell 10, so that the inner liner 20 is locked by the outer shell 10 and the inner liner 20 is kept in the position embedded in the outer shell 10.

[0056] Preferably, in this specific example of the double-layer container of the present invention, the outer shell 10 has two slide grooves 12, two guide grooves 13 and two locking grooves 14, one slide groove 12, one guide groove 13 and one locking groove 14 are located on one side of the outer shell 10, and another slide groove 12, another guide groove 13 and another locking groove 14 are located on the other side of the outer shell 10. Correspondingly, the outer wall of the inner liner 20 has two locking protrusions 22, and the two locking protrusions 22 are located on opposite sides of the inner liner 20, wherein in the process of embedding the inner liner 20 in the outer shell 10, the two locking protrusions 22 of the inner liner 20 are allowed to move downward along the two slide grooves 12 of the outer shell 10 respectively, and the two locking protrusions 22 of the inner liner 20 are allowed to slide to the two locking grooves 14 of the outer shell 10 at the same time, so that the outer shell 10 can lock the inner liner 20 on opposite sides of the inner liner 20 to prevent the inner liner 20 from tilting in the outer shell 10.

[0057] It can be understood that after the locking protrusion 22 of the inner liner 20 slides to the locking groove 14 of the outer shell 10, the outer shell 10 can lock the inner liner 20 because: first, the locking groove 14 does not extend upward to the outer shell top edge 15 of the outer shell 10, so that the outer shell 10 can limit the inner liner 20 from moving up in the height direction and detaching from the outer shell 10; second, the repulsive force generated between the first magnet 41 and the second magnet 42 can push the inner liner 20 upward to ensure that the locking protrusion 22 of the inner liner 20 is located in the locking groove 14 of the outer shell 10, thereby preventing the inner liner 20 from automatically rotating in the circumferential direction and causing the locking protrusion 22 of the inner liner 20 to enter the slide groove 12 through the guide groove 13 of the outer shell 10.

[0058] When the inner liner 20 needs to be separated from the outer shell 10, the user can rotate the inner liner 20 in the opposite direction so that the locking protrusion 22 of the inner liner 20 disengages from the locking groove 14 of the outer shell 10 and enters the slide groove 12 through the guide groove 13 of the outer shell 10. At this time, the repulsive force generated between the first magnet 41 and the second magnet 42 can push the inner liner 20 upward, so that the inner liner 20 moves up and causes the top of the inner liner 20 to move away from the top of the outer shell 10, making it convenient for the user to pinch the opposite sides of the top of the inner liner 20 with his fingers to easily take out the inner liner 20.

[0059] Reference Figure 2 and Figure 3 The inner liner 20 has an inner liner top edge 23 and at least one ear 24, the inner liner top edge 23 protrudes from the outer wall of the inner liner 20, and the ear 24 extends downward from the inner liner top edge 23, so that there is a gap between the outer wall of the inner liner 20 and the ear 24. After the inner liner 20 is embedded in the outer shell 10, a part of the outer shell top edge 15 of the outer shell 10 can be located in the gap between the outer wall of the inner liner 20 and the ear 24, that is, the ear 24 of the inner liner 20 can be exposed to the outside of the outer shell 10, so as to allow the user to rotate the inner liner 20 through the ear 24. That is, by arranging the ear 24 on the inner liner 20, when the inner liner 20 needs to be replaced, the double-layer container facilitates the user to apply force to the inner liner 20 through the ear 24 to rotate the inner liner 20 relative to the outer shell 10.

[0060] Preferably, the shell 10 is provided with at least one groove 16 at the position of the top edge 15 of the shell, the depth dimension of the groove 16 is not less than the thickness dimension of the ear portion 24 of the inner liner 20, and the length dimension of the groove 16 in the circumferential direction is greater than the length dimension of the ear portion 24 of the inner liner 20 in the circumferential direction, wherein the ear portion 24 of the inner liner 20 is located in the groove 16 of the shell 10, and when the inner liner 20 is rotated, the ear portion 24 of the inner liner 20 can move in the groove 16 of the shell 10, so that the double-layer container can prevent the ear portion 24 of the inner liner 20 from protruding from the outer surface of the shell 10, so as to facilitate the installation of the cover body 30 on the shell 10. That is, by allowing the ear portion 24 of the inner liner 20 to be located in the groove 16 of the shell 10, it can be prevented that the ear portion 24 of the inner liner 20 interferes with the installation of the cover body 30.

[0061] Preferably, the number of the ears 24 of the inner liner 20 may be two, and the two ears 24 are symmetrical to each other. Correspondingly, the number of the grooves 16 of the outer shell 10 is also two, and the two grooves 16 are symmetrical to each other.

[0062] Reference Figure 2 The inner wall of the outer shell 10 for defining the guide groove 13 is a slope 131, and the height of the end of the slope 131 close to the slide groove 12 is higher than the height of the end close to the lock groove 14. In this way, when the new inner liner 20 is embedded in the outer shell 10, when the inner liner 20 is rotated, the locking protrusion 22 of the inner liner 20 can smoothly slide from the slide groove 12 into the lock groove 14 through the guide groove 13 of the outer shell 10.

[0063] Reference Figure 4 , the distance D1 between the top of the locking groove 14 of the shell 10 and the top edge 15 of the shell is smaller than the distance D2 between the locking protrusion 22 of the liner 20 and the top edge 23 of the liner, so that after the cover 30 is separated from the shell 10, the repulsive unit 40 can push the liner 20 upward, so that the liner 20 is suspended in the shell 10, so as to enhance the visual experience of the double-layer container and improve the use experience of the double-layer container. It can be understood that, since the locking groove 14 of the shell 10 does not extend to the top edge 15 of the shell 10, the shell 10 can limit the distance that the liner 20 moves upward to prevent the liner 20 from falling from the shell 10.

[0064] That is to say, the inner liner 20 of the utility model has a separation position and a suspension position, and the inner liner 20 can be switched between the separation position and the suspension position by rotating the inner liner 20, wherein when the inner liner 20 is in the separation position, the locking protrusion 22 of the inner liner 20 is located in the slide groove 12 of the outer shell 10, and the inner liner 20 is allowed to be separated from the outer shell 10, and correspondingly, when the inner liner 20 is in the suspension position, the locking protrusion 22 of the inner liner 20 is located in the locking groove 14 of the outer shell 10, and the inner liner 20 is prevented from being separated from the outer shell 10. When the inner liner 20 is rotated in one direction, the locking protrusion 22 of the inner liner 20 can slide from the slide groove 12 to the locking groove 14 through the guide groove 13 of the outer shell 10, so that the inner liner 20 switches from the separation position to the suspended position. When the inner liner 20 is rotated in the opposite direction, the locking protrusion 22 of the inner liner 20 can slide from the lock groove 14 to the slide groove 12 through the guide groove 13 of the outer shell 10, so that the inner liner 20 switches from the suspended position to the separation position.

[0065] Continue to attach Figure 2 The shell 10 has at least one pair of blocking blocks 17, in the circumferential direction, one of the blocking blocks 17 is located on one side of the slide groove 12, and the other is located on one side of the locking groove 14, and from a side view, the slide groove 12, the guide groove 13 and the locking groove 14 are located between the pair of blocking blocks 17, wherein the distance between the bottom of the blocking block 17 and the top edge 15 of the shell 10 is greater than the distance between the locking protrusion 22 of the liner 20 and the top edge 23 of the liner 20, when the liner 20 is rotated, the pair of blocking blocks 17 blocks the locking protrusion 22 of the liner 20 in two directions, so that the locking protrusion 22 of the liner 20 can only slide from the slide groove 12 into the locking groove 14 through the guide groove 13 of the shell 10 or slide from the locking groove 14 into the slide groove 12 through the guide groove 13.
