Description

Technical Field

[0001] The present application relates to the technical field of containers, and in particular to a multi-nested structure for facilitating liquid collection. Background Art

[0002] A container refers to a basic device mainly composed of a shell for holding materials. Various containers are often used in daily life to hold different kinds of items. In the packaging of medicines, food, and daily chemical products, the packaging for liquids is mostly a plastic bottle and a pump head.

[0003] The liquid in the plastic bottle is pumped out through the pump head. When the amount of liquid is reduced to a certain amount, the remaining liquid is difficult to pump out. At this time, it is often necessary to remove the pump head and then tilt the plastic bottle to pour out the remaining liquid in the plastic bottle.

[0004] When the amount of liquid is reduced to a level that is difficult to pump out, the user needs to disassemble the pump head to take out the remaining liquid, which is troublesome to operate and inconvenient to use. Summary of the Invention

[0005] For user convenience, the present application provides a multi-nested structure that is convenient for taking liquid.

[0006] The present application provides a multi-nested structure for facilitating liquid collection using the following technical solutions:

[0007] A multi-nested structure for facilitating liquid collection comprises an outer shell, an inner wall of the top of the outer shell is provided with a mounting platform in an annular manner, a mounting seat is provided on the surface of the mounting platform, an outer wall of the mounting seat is fixedly connected to the connecting seat, an end face at the opening of the outer shell is provided with a connecting groove which is plugged and adapted to the connecting seat, the connecting groove and the mounting platform are communicated, an inner sleeve is provided in the outer shell, the inner sleeve is made of soft material, an end portion of the inner sleeve is fixedly connected to a mounting plate, the mounting plate is provided between the mounting seat and the mounting platform, and a mounting assembly for fixing the mounting plate and the outer shell is provided on the top of the outer shell.

[0008] The above technical solution, with its dual-layer design of outer shell and inner sleeve, and the inner sleeve made of soft material, creates negative pressure inside the inner sleeve as the amount of liquid inside decreases, causing it to deform and shrink. This structure allows the remaining liquid inside to be removed without disassembling the pump head, making it easier for users to use.

[0009] Optionally, the mounting assembly includes a transmission rod, a limit rod and a linkage rod, a first cavity is provided in the connecting seat, a first slide groove connecting the first cavity with the outside world is provided on the connecting seat, the transmission rod is arranged in the first slide groove, one end of the transmission rod extends into the first cavity, a second slide groove connecting the second cavity with the outside world is provided in the mounting seat, the limit rod is arranged in the second slide groove, one end of the limit rod extends into the second cavity, the other end of the limit rod is used to fix the mounting plate, an elastic component for resetting the limit rod is provided in the second cavity, and a first through groove and a second through groove are respectively provided on the opposite surfaces of the connecting seat and the mounting seat, the first through groove and the second through groove connect the first cavity and the second cavity, the linkage rod passes through the first through groove and the second through groove, and a trigger component for driving the transmission rod to move is provided in the shell.

[0010] By adopting the above technical solution, the transmission rod is squeezed against the linkage rod through the trigger component, and the linkage rod is squeezed against the limit rod, so that the limit rod presses the mounting plate and the outer shell tightly, thereby fixing the end of the inner sleeve to the outer shell, which is convenient and quick to install.

[0011] Optionally, the elastic component includes a reset plate and a reset spring, the reset plate is sleeved on the limit rod and the two are fixedly connected, one end of the reset spring is fixedly connected to the reset plate, and the other end of the reset spring is connected to the mounting seat.

[0012] By adopting the above technical solution, when the limit rod is squeezed, the limit rod compresses the reset spring through the reset plate; when the limit rod is not squeezed, the reset spring releases the elastic force to move the limit rod away from the mounting plate through the reset plate, thereby removing the inner sleeve from the outer shell, achieving the effect of convenient replacement of the inner sleeve.

[0013] Optionally, the end of the limiting rod extending out of the second cavity is fixedly connected to a spike, and the housing is provided with a socket on the surface of the mounting platform that is plugged into and adapted to the spike.

[0014] By adopting the above technical solution, when the limit rod is squeezed, the limit rod passes through the mounting plate through the spike, thereby inserting the spike into the socket, thereby preventing relative sliding between the mounting plate and the outer shell, thereby achieving the effect of improving the stability of the inner sleeve installation.

[0015] Optionally, a spiral groove is spirally opened on the inner wall of the mounting seat at the second slide groove, and a trigger block that is slidably adapted to the spiral groove is fixed on the outer wall of the limiting rod; a turntable is provided in the second cavity, the turntable is rotatably connected to the mounting seat, and the turntable is fixedly connected to the second reset spring.

[0016] By adopting the above technical solution, when the limit rod is squeezed, the limit rod moves toward the mounting plate, so that the limit rod causes the trigger block to slide along the spiral groove, and then the limit rod rotates in the first sliding groove. The rotation of the limit rod causes the spike to rotate; when the spike contacts the mounting plate, the spike can rotate more easily through the mounting plate.

[0017] Optionally, a guide block is fixedly connected to the side of the turntable facing away from the reset spring, and a guide groove that is slidingly adapted to the guide block is opened on the inner wall of the mounting seat at the second cavity, and a ball bearing that is rolling adapted to the guide groove is ball-hinged on the side wall of the guide block.

[0018] By adopting the above technical solution, when the limit rod rotates, the reset spring generates torque, and the turntable rotates through the torque generated by the reset spring. At the same time, the sliding friction between the turntable and the guide rod is replaced by rolling friction, reducing the friction between the guide block and the mounting seat, so that the turntable rotates smoothly, thereby playing the role of buffering the torque generated by the reset spring.

[0019] Optionally, the housing is fixedly connected to a positioning rod on the surface of the connecting groove, and the connecting seat is provided with a positioning hole that is plugged and adapted to the positioning rod.

[0020] By adopting the above technical solution, the position of the limit rod is established by plugging and adapting the positioning rod and the positioning hole, so that the spike is aligned with the hole; the positioning rod makes it difficult for the connecting seat to slide relative to the shell, thereby improving the connection stability between the connecting seat and the shell.

[0021] Optionally, the trigger assembly includes a connecting ring, a trigger groove is provided in a ring shape on the end face of the shell opening, the trigger groove is connected to the connecting groove, the connecting ring is arranged in the trigger groove, the connecting ring is threadedly connected to the shell, and the connecting ring is used to squeeze the transmission rod.

[0022] Using the above technical solution, the connecting ring is screwed into the trigger groove. During the screwing process, the connecting ring squeezes the transmission rod. At the same time, the connecting ring and the outer shell are threadedly connected. The threaded connection has self-locking properties, so that the connecting ring and the outer shell can maintain stability.

[0023] Optionally, a connecting plate is provided in the first cavity, the connecting plate is sleeved on the transmission rod and the two are fixedly connected, and a connecting spring is provided in the first cavity, and both ends of the connecting spring are fixedly connected to the connecting seat and the connecting plate respectively.

[0024] With this technical solution, when the transmission rod is squeezed, the transmission rod stretches the connecting spring through the connecting plate; when the transmission rod is unsqueezed, the connecting spring releases its elastic force through the connecting plate, causing the transmission rod to return to its original position. This structure prevents the transmission rod from easily detaching from the connecting seat.

[0025] Optionally, the inner wall of the mounting seat at the second through groove is fixedly connected to a limiting block, and the outer wall of the linkage rod is provided with a limiting groove that is slidably adapted to the limiting block.

[0026] With the above technical solution, when the linkage rod slides, the limiting block slides along the limiting groove, thereby making it difficult for the linkage rod to escape from the first through groove and the second through groove.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the double-layer design of the outer shell and inner sleeve, as the amount of liquid inside continues to decrease, negative pressure will be formed inside the inner sleeve, causing it to deform and shrink, making it easier for users to use;

[0029] 2. Screw the connecting ring into the connecting groove. At this time, the transmission rod squeezes the limit rod through the linkage rod, so that the limit rod moves toward the mounting plate. The spike then passes through the mounting plate and is inserted into the socket, making it easy to install and fix the inner sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

The outer wall of the top of the outer shell 1 is provided with a thread for connecting to the pump head. The pump head is designed to exhaust air but not intake air. The outer shell 1 is connected to the pump head. An inner sleeve 13 is arranged in the vertical direction inside the outer shell 1. The inner sleeve 13 is made of a soft material. In the embodiment of the present application, the inner sleeve 13 is made of soft plastic. The top of the inner sleeve 13 is connected to the inner wall of the top of the outer shell 1.

[0039] Place the inner sleeve 13 inside the outer shell 1, then secure the interior of the inner sleeve 13 to the top of the outer shell 1. Pour the liquid to be stored into the inner sleeve 13, and then connect the pump head to the top of the outer shell 1 to complete the assembly. After assembly, the user presses the pump head to remove the liquid from the inner sleeve 13. As the liquid decreases, negative pressure is generated inside the inner sleeve 13, causing the inner sleeve 13 to deform and contract, facilitating the removal of the liquid from the inner sleeve 13.

[0040] refer to Figure 2 A trigger groove 15 is provided in an annular shape on the end face of the opening of the shell 1. A trigger assembly 6 is provided on the top of the shell 1.

[0041] refer to Figure 2 and Figure 3 A mounting platform 11 is provided in an annular manner on the inner wall at the top of the shell 1, and a mounting seat 2 is provided on the surface of the mounting platform 11. A connecting seat 3 is fixedly connected to the outer wall of the mounting seat 2. The connecting seat 3 is stepped, and there are four connecting seats 3. The four connecting seats 3 are evenly spaced around the central axis of the shell 1.

[0044] Place the mounting base 2 on the surface of the mounting table 11, and put the connecting base 3 into the connecting groove 12. At this time, the positioning rod 8 is plugged into the positioning hole 34, and then the connecting ring 61 is screwed into the trigger groove 15. The connecting ring 61 squeezes the transmission rod 41. The transmission rod 41 is squeezed and stretches the connecting spring 412 through the connecting plate 411, thereby fixing the mounting base 2 and the connecting base 3 to the outer shell 1; when the connecting ring 61 is screwed out of the trigger groove 15, the transmission rod 41 is not squeezed at this time, and the link spring releases the elastic force to reset the transmission rod 41 through the connecting plate 411, thereby removing the mounting base 2 and the connecting base 3 from the outer shell 1.

[0045] refer to Figure 3 and Figure 4 A second cavity 21 is provided in the mounting seat 2, and a first through groove 33 and a second through groove 23 are respectively provided on the opposite surfaces of the connecting seat 3 and the mounting seat 2. The first through groove 33 and the second through groove 23 are both provided in the horizontal direction. The first through groove 33 and the second through groove 23 connect the first cavity 31 and the second cavity 21. The mounting assembly 4 also includes a linkage rod 42, which passes through the first through groove 33 and the second through groove 23. The inner wall of the mounting seat 2 at the second through groove 23 is fixedly connected to the limiting block 9, and the outer wall of the linkage rod 42 is provided with a limiting groove 421 that is slidably adapted to the limiting block 9.

[0046] refer to Figure 3 and Figure 5 The bottom wall of the mounting base 2 is provided with a second slide groove 22 connecting the second cavity 21 with the outside world. The second slide groove 22 is opened in the vertical direction. The mounting assembly 4 also includes a limit rod 43. The limit rod 43 is arranged in the second slide groove 22 in the vertical direction. The top end of the limit rod 43 extends into the second cavity 21. The bottom end of the limit rod 43 is fixedly connected with a spike 431. The surface of the shell 1 at the mounting platform 11 is provided with a socket 14 that is plugged into the spike 431, and the socket 14 is aligned one by one with the positioning rod 8.

[0047] refer to Figure 5 The inner wall of the mounting seat 2 at the second slide groove 22 is spirally opened with a spiral groove 24, and the outer wall of the limiting rod 43 is fixedly connected with a trigger block 432 that slides with the spiral groove 24, and the trigger block 432 is hemispherical.

[0048] refer to Figure 5The mounting seat 2 is provided with a turntable 7 at the inner bottom wall of the second cavity 21. The bottom wall of the turntable 7 is fixedly provided with a guide block 71 in an annular shape. The cross-section of the guide block 71 is T-shaped. The mounting seat 2 is provided with a guide groove 25 in an annular shape on the inner bottom wall of the second cavity 21 for slidingly matching the guide block 71. The side walls of the guide block 71 are spherically hinged with balls 711 that are rollingly matched with the guide groove 25.

[0049] refer to Figure 5 An elastic component 5 is provided in the second cavity 21. The elastic component 5 includes a reset plate 51 and a reset spring 52. The reset plate 51 is sleeved on the limit rod 43 and the two are fixedly connected. One end of the reset spring 52 is fixedly connected to the reset plate 51, and the other end of the reset spring 52 is fixedly connected to the turntable 7.

[0050] refer to Figure 3 The inner sleeve 13 is fixedly connected to a mounting plate 131, which is arranged between the surface of the mounting platform 11 and the mounting seat 2. The bottom wall of the mounting plate 131 abuts against the surface of the mounting platform 11, and the surface of the mounting plate 131 abuts against the bottom wall of the mounting seat 2.

[0051] When the transmission rod 41 is squeezed, the transmission rod 41 squeezes the limiting rod 43 through the linkage rod 42. The squeezed limiting rod 43 drives the spike 431 toward the mounting plate 131 until the spike 431 passes through the mounting plate 131 and is inserted into the insertion hole 14. At this time, the limiting rod 43 drives the reset plate 51 to compress the reset spring 52, thereby fixing the mounting plate 131 to the housing 1. When the transmission rod 41 is not squeezed, the reset spring 52 releases its elastic force and resets the limiting rod 43 through the reset plate 51, thereby driving the limiting rod 43 to disengage the spike 431 from the insertion hole 14, thereby allowing the mounting plate 131 to be removed from the housing 1. During the process of inserting the spike 431 into the insertion hole 14, the limiting rod 43 drives the trigger block 432 to slide along the spiral groove 24, causing the limiting rod 43 to rotate about its own central axis. As a result, the limiting rod 43 drives the spike 431 to rotate, facilitating the spike 431 to pass through the mounting plate 131. During the rotation of the limiting rod 43 , the limiting rod 43 drives the reset plate 51 to rotate. The reset plate 51 rotates the turntable 7 through the reset spring 52 . The turntable 7 drives the guide block 71 to slide along the guide groove 25 , so that the ball 711 rolls along the guide groove 25 .

[0052] The implementation principle of the multi-nested structure for facilitating liquid extraction in the embodiment of the present application is as follows: the inner sleeve 13 is placed inside the outer shell 1, and then the mounting plate 131 is placed on the surface of the mounting platform 11. The mounting plate 131 is then pressed by the fixing seat, and the connecting seat 3 is embedded in the connecting groove 12. The connecting ring 61 is then screwed into the trigger groove 15, thereby fixing the mounting plate 131 to the outer shell 1 through the mounting assembly 4. The liquid to be stored is then poured into the inner sleeve 13, and finally the pump head is connected to the top of the outer shell 1 to complete the assembly. After the assembly is completed, the user removes the liquid from the inner sleeve 13 by pressing the pump head. As the liquid decreases, a negative pressure is formed inside the inner sleeve 13, causing the inner sleeve 13 to deform and shrink. Through the above structure, it is convenient for the user to remove the liquid from the inner sleeve 13.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
