The shape of the connecting ring 46 and the transition ring 47 after cooperation is similar to that at the center of the piston 3, which can maximize the stroke of the piston 3 upward and maximize the guarantee that there is no residual liquid above the piston 3 after use.

[0040] The outer bottle 1 is connected with an outer bottle shoulder 5 at the upper end, the outer bottle shoulder 5 comprises an integral outer bottle shoulder base ring 52, an outer bottle shoulder convex ring 51 and an outer bottle shoulder upper edge part 53, referring to Figure 7 , the outer wall of the outer bottle shoulder convex ring 51 is circumferentially provided with a tab 54, the tab 54 is divided into two parts arranged in an upper and lower interval, each part forms a ring shape, and adjacent two tab 54s forming a ring shape leave a gap, the tab 54 is in interference fit with the inner wall of the upper part of the outer bottle 1, the outer bottle shoulder 5 and the outer bottle 1 are adhered together by applying glue outside the outer bottle shoulder convex ring 51, the gap between adjacent tab 54s can accommodate glue, so that the outer bottle shoulder 5 and the outer bottle 1 are firmly bonded.

[0041] Referring to Figure 11 , Figure 12The shoulder sleeve 6 comprises a shoulder sleeve base plate 61, an upper shoulder sleeve convex ring 62 and a lower shoulder sleeve convex ring 64, the upper shoulder sleeve convex ring 62 is connected to the outer edge of the upper end of the shoulder sleeve base plate 61, the inner edge of the shoulder sleeve base plate 61 is connected with a mounting seat 63, the upper end of the mounting seat 63 exceeds the upper end of the shoulder sleeve base plate 61, the lower end of the mounting seat 63 exceeds the lower end of the shoulder sleeve base plate 61, the outer diameter of the lower shoulder sleeve convex ring 64 is smaller than the outer diameter of the shoulder sleeve base plate 61, the upper part of the inner wall of the outer bottle shoulder convex ring 51 is provided with a connecting part three 55, the connecting part three 55 is a groove, the outer wall of the lower shoulder sleeve convex ring 64 is provided with a connecting part four 641, the connecting part four 641 is a convex, and the connecting part four 641 is connected with the connecting part three 55 through buckling. The shoulder sleeve 6 can be connected with the outer bottle shoulder 5 through concentric rotation.

[0042] Referring to Figure 5 The inner wall of the upper convex part 41 is circumferentially provided with a plurality of convex bodies one 42, and the outer wall of the upper convex part 41 is circumferentially provided with a plurality of convex bodies two 43, the convex bodies one 42 and the convex bodies two 43 are circumferentially distributed, and the number of the convex bodies one 42 and the convex bodies two 43 is four. The convex bodies one 42 comprise convex body one arc heads 421 at the upper end and convex body one side parts 422 at both sides, and the convex bodies one 42 except the convex body one arc heads 421 are approximately cuboids. The inner wall of the upper convex part 41 is provided with an inner convex ring 49, and the lower end of the convex bodies one 42 is connected to the upper end surface of the inner convex ring 49. The inner convex ring 49 plays the role of a reinforcing rib.

[0043] Referring to Figure 5 The convex bodies two 43 are approximately triangular, and the top angle of the triangle is transitioned through a circular arc, that is, the convex bodies two 43 comprise convex body two arc heads 431 at the top end. The two bottom angles of the triangle are transitioned through vertical straight planes, that is, the convex bodies two 43 comprise two vertical transition parts 433. The triangle comprises two side edges, that is, the convex bodies two 43 comprise convex body two side parts 432 between the convex body two arc heads 431 and the transition parts 433, and the number of the convex body two side parts 432 is two and symmetrically distributed. The triangle comprises one bottom edge, that is, the convex bodies two 43 comprise convex body two bottom parts 434 at the bottom surface.

[0044] The convex bodies two 43 are separated from the limiting area and are bounced downward under the elastic force of the block bodies two 582 to make the inner bottle 2, the piston 3 and the inner bottle shoulder 4 bounce out together, and the lower end surface of the inner bottle 2 exceeds the lower end port of the outer bottle 1 after bouncing out.

[0045] Referring to Figure 6 The outer bottle shoulder 5 comprises a plurality of block bodies 58 circumferentially distributed and having elasticity, the number of the block bodies 58 is twice the number of the convex bodies two 43, and the number of the block bodies 58 is eight and is circumferentially distributed. The block bodies 58 are circumferentially distributed on the inner edge of the outer bottle shoulder base ring 52.

[0046] The block bodies 58 comprise block bodies one 581 and block bodies two 582, the block bodies one 581 are connected to the inner edge of the outer bottle shoulder base ring 52, and the block bodies two 582 are connected to the outer wall of the outer bottle shoulder convex ring 52.Figure 9 The block one 581 is connected to the upper end surface of the outer bottle shoulder base ring 52 and connected to the circumferential inner wall of the outer bottle shoulder base ring 52, so that the block one 581 has strong connection firmness and reliability.

[0047] The block two 582 includes a block inclined part 5821 and a block head part 5822, and the block one 581 and the block head part 5822 are connected through the block inclined part 5821. In each block 58, the block one 581 and the block head part 5822 are respectively located at two ends, the height of the block head part 5822 is higher than the height of the block one 581, and the block inclined part 5821 located on one side of the block head part 5822 is higher than the block inclined part 5821 located on one side of the block one 581. The lower end surface of the block inclined part 5821 is an inclined surface, and the block inclined part 5821 is approximately a cuboid, that is, the upper end of the block inclined part 5821 is also an inclined surface. The block two 582 has good elastic deformation capacity, especially the block inclined part 5821.

[0048] With reference to Figure 9 The upper end of the block one 581 is provided with a stepped gap, the stepped gap is located on one side of the block head part 5822 close to the adjacent block 58, and the stepped gap includes a stepped surface one 5811 and a stepped surface two 5812. The stepped gap is a right-angle stepped gap, the stepped surface one 5811 is a vertical plane, and the stepped surface two 5812 is a horizontal plane. By providing the stepped gap, the thickness of the upper end of the block one 581 and one side of the block head part 5822 of the adjacent block 58 is small, and the upper end of the block one 581 also has elastic deformation capacity.

[0049] With reference to Figure 15 The upper end of the block one 581 and the block head part 5822 of the adjacent two blocks 58 close to each other form a limiting area, and the convex body two 43 is buckled into the limiting area between the corresponding adjacent two blocks 58. Specifically, the stepped gap and the block head part 5822 of the adjacent two blocks 58 close to each other form a limiting area.

[0050] The eight blocks 58 can be divided into four groups, and two blocks 58 in each group are matched with one convex body two 43. Each convex body two 43 corresponds to the limiting area between the two blocks 58 in each group. That is, between the two blocks 58 in each group, the upper end of the block one 581 of one of the two blocks 58 and the block head part 5822 of the other block 58 form a limiting area, and the upper end of the block one 581 and the block head part 5822 are close to each other. Specifically, with reference to Figure 15In any one limiting area, the transition part 433 on one side (the transition part 433 on the left side) at least partially abuts against the step surface one 5811, the convex body two bottom part 434 at least partially abuts against the step surface two 5812, and the convex body two side part 432 on the other side (which can be referred to as the convex body two side part 432 away from the left side transition part 433 or the convex body two side part 432 on the right side) at least partially abuts against the block body two 582. Specifically, the convex body two side part 432 on the other side at least partially abuts against the junction of the block body inclined part 5821 and the block body head part 5822, which is the junction of the step gap of the other block body 58 (i.e. the left junction, not the right junction). Figure 15

[0051] Referring to Figure 12 , the shoulder sleeve 6 includes circumferentially distributed teeth 631 at the lower end, the number of the teeth 631 is twice the number of the convex body one 42, i.e. the number of the teeth 631 is 8, two teeth 631 in each group are matched with one convex body one 42, and each convex body one 42 corresponds to the area between the two teeth 631 in each group, and the convex body one arc head 421 can be guided into or out of the teeth 631 along the tooth surface 6311. The teeth 631 are circumferentially distributed on the lower end surface of the mounting seat 63, and the teeth 631 include tooth surfaces 6311, each tooth 631 includes two tooth surfaces 6311, and the adjacent two teeth 631 are transitioned by a circular arc.

[0052] The convex body one 42 can be guided out of the teeth 631 along the tooth surface 6311 to make the convex body two 43 disengage from the limiting area and be bounced down under the elastic force of the block body two 582. Referring to Figure 14 When in the normal use state, the convex body one arc head 421 of the convex body one 42 is almost at the top of the space between the adjacent two teeth 631 in each group, i.e. the convex body one arc head 421 is almost at the top end position of the tooth surface 6311. Referring to Figure 15 When in the normal use state, the convex body two 43 extrudes the block body one 581 and the block body head part 5822 on its two sides, and the block body one 581 and the block body head part 5822 are both deformed to a certain extent, and the block body head part 5822 is bent upward to a greater extent.

[0053] ​During operation, one hand holds the outer bottle 1, while the other hand rotates the shoulder sleeve 6. The rotation of the shoulder sleeve 6 causes the teeth 631 to rotate as well. The tooth surface 6311 presses against the convex arc head 421 of the convex one 42, causing the convex arc head 421 to descend along the tooth surface 6311. As the convex arc head 421 descends, it also causes the convex two 43 to descend. Once the convex two 43 leaves the limiting area, both the block one 581 and the block head 5822 need to return to their initial positions. In particular, the block head 5822, which has a larger elastic deformation range, will move downwards to return to its initial position, thereby pushing the convex two 43 downwards. This causes the lower end of the inner bottle 2 to extend beyond the lower end of the outer bottle 1. In this way, the inner bottle 2 can be removed by hand for replacement with new packaging. The new packaging includes a new inner bottle 2, piston 3, and inner bottle shoulder 4. The inner bottle shoulder 4 of the new packaging also has a sealing cap, which can be removed before installation.

[0054] The lower outer wall of the inner bottle 2 is provided with circumferentially distributed fastening parts 21. The fastening parts 21 are interference-fitted with the inner wall of the outer bottle 1. Due to the setting of the fastening parts 21, the inner bottle 2 will not fall off directly when it pops out of the lower end of the outer bottle 1. Instead, it will continue to be supported inside the outer bottle 1 by the fastening parts 21. Thus, the inner bottle 2 needs to be removed by hand.

[0055] Reference Figure 6 , Figure 10 The outer bottle shoulder 5 includes a lower notch 57 located around the block 58. There are two lower notches 57. The lower notches 57 include a third notch 571 and a fourth notch 572 that are connected. The third notch 571 is located on the lower inner wall of the outer bottle shoulder protrusion ring 51. The fourth notch 572 is located on the outer edge of the outer bottle shoulder base ring 52. The third notch 571 and the fourth notch 572 are corresponding to each other and have the same circumference. The upper end of the third notch 571 extends beyond the upper end of the outer bottle shoulder base ring 52.

[0056] Reference Figure 12 The shoulder sleeve 6 includes two connecting pieces 65 located around the tooth 631. The lower convex ring 64 of the shoulder sleeve is separated by the connecting pieces 65, and there is a gap between the connecting pieces 65 and the lower convex ring 64 of the shoulder sleeve. The lower end of the connecting piece 65 is provided with an outwardly protruding connecting head 651. The outer edge of the shoulder sleeve base plate 61 is provided with a base plate notch 611. The upper end of the connecting piece 65 is located at the base plate notch 611. This arrangement gives the connecting piece 65 good elastic deformation ability.

[0057] Reference Figure 15 , Figure 16The circumferential length of the connecting head 651 is less than that of the lower notch 57. The connecting head 651 extends into the lower notch 57, i.e. the connecting head 651 moves within the range between the circumferential ends of the lower notch 57. When the connecting head 651 rotates clockwise or counterclockwise, it will stop at the boundary of the third notch 571, i.e. the connecting head 651 can move within the range of the lower notch 57. The fourth notch 572 serves as a clearance groove, making it more convenient for the connecting head 651 to be buckled into the third notch 571.

[0058] The movement of the connecting head 651 drives the tooth surface 6311 to push the convex body one 42 away (i.e. the convex body one 42 descends) to make the convex body two 43 disengage from the limiting area and pop out downward under the elastic force of the block body two 582. The arrangement of the lower notch 57 limits the rotation range of the shoulder sleeve 6 and facilitates positioning and installation.

[0059] When the new package is installed, the outer bottle 1 is directly inserted from the bottom up. The convex body one arc head 421 of the convex body one 42 rises along the corresponding tooth surface 6311, and the convex body two arc head 431 can be guided into the limiting area along the lower end surface of the block body inclined part 5821. During the insertion of the convex body one arc head 421, if the connecting head 651 is not at the right end of the lower notch 57 (with the only visible lower notch 57 as a reference), the convex body one 42 will first rotate the shoulder sleeve 6, so that the connecting head 651 abuts against the right end of the lower notch 57. After that, the convex body one 42 will rise along the tooth surface 6311 until the convex body two 43 is buckled into the limiting area. When the connecting head 651 rotates from the right end to the left end of the lower notch 57, the inner bottle 2 is ejected from the lower end of the outer bottle 1. Figure 6

[0060] Referring to Figure 2 The lower end of the mounting seat 63 is inserted into the upper convex part 41, and the outer diameter of the lower end of the mounting seat 63 is less than the inner diameter of the upper end of the upper convex part 41.

[0061] Referring to Figure 6 , Figure 9 The inner wall of the outer bottle shoulder convex ring 51 is provided with an upper notch 56. The number of the upper notch 56 is the same as that of the connecting piece 65. The upper notch 56 is opposite to the lower notch 57. The circumferential length of the upper notch 56 is greater than that of the connecting piece 65. The circumferential length of the upper notch 56 can be equal to that of the lower notch 57. The connecting part three 55 is separated by the upper notch 56. The inner wall of the connecting part three 55 and the inner wall of the upper notch 56 are located on the same ring surface, i.e. the connecting part three 55 is still a complete ring in fact. When installing, the connecting head 651 is assembled into the lower notch 57 along the upper notch 56.

[0062] Referring to Figure 2 ​The lower end surface of the lower convex ring 64 of the shoulder sleeve abuts against the upper end surface of the outer bottle shoulder base ring 52. The mounting seat 63 is provided with a pump 7. The lower end of the pump 7 is fitted into the outer wall of the inner ring cylinder 48. The upper end of the pump 7 is provided with a pressing head 8. One side of the pressing head 8 is provided with a nozzle 81 which is communicated with the pump 7. The nozzle 81 penetrates through the gap two 622. The pressing head 8 extends into the upper convex ring 62 of the shoulder sleeve. A gap is left between the outer wall of the pressing head 8 and the inner wall of the upper convex ring 62 of the shoulder sleeve.

[0063] With reference to Figure 11 The upper end surface of the upper convex ring 62 of the shoulder sleeve is provided with a gap one 621 and a gap two 622. The lower ends of the gap one 621 and the gap two 622 are arc-shaped. The nozzle 81 can move along the gap two 622. When the finger presses the pressing head 8, the finger can extend into the gap one 621.

[0064] The above description is only the preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
