Description

Technical Field

[0001] This invention relates to cream jars, and more particularly to a press-type cream jar. Background Technology

[0002] In Chinese invention patent application CN103373544A, the inventor disclosed a paste dispensing packaging, which includes a paste dispensing component, a container, and a top cap. The top cap is detachably connected to the container opening. The paste dispensing component includes a rotating cap that can adhere to the paste. The rotating cap has a lower surface that can adhere to the paste, an upper surface opposite to it, and an outer peripheral surface connecting the upper and lower surfaces. A dispensing opening is formed through the upper and lower surfaces, and a spatula is located below the dispensing opening. The spatula is integrally formed with the rotating cap. The spatula has a spatula surface facing the rotating cap and used to guide the paste into the dispensing opening. The dispensing opening has a first opening edge and a second opening edge, which are arranged facing each other. The spatula is fixed to one side of the first opening edge of the rotating cap and extends to one side of the second opening edge. The first opening edge and the second opening edge are arranged sequentially along the rotation direction of the rotating cap. The front end of the spatula surface is lower than the lower surface of one side of the second opening edge. When dispensing, the rotating cap rotates against the paste, and the paste enters the dispensing opening along the spatula surface and continues to enter the upper surface of the rotating cap. In existing paste dispensing packaging, it is required to hold the handle with one hand and rotate the rotating cap with the other hand to dispense the paste. The operation is cumbersome and cannot be operated with one hand, thus its applicability is limited. Furthermore, the amount of ointment dispensed is related to the rotation angle of the rotating cap. The smaller the rotation angle, the smaller the amount of ointment dispensed, and the larger the rotation angle, the larger the amount of ointment dispensed. However, the ointment dispensing packaging does not have a structure to control the rotation angle of the rotating cap, which makes it impossible for users to dispense a fixed amount of ointment, easily leading to waste or insufficient use of the ointment.

[0062] Refer to the accompanying drawings of the specification of this invention. Figures 1 to 12 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the press-type cream jar includes a bottom shell 10, a track forming part 20, a cap assembly 30, a reset element 40, and a bottle body assembly 50.

[0063] Specifically, the track forming portion 20 has a post hole 21 and a track groove 22, the track groove 22 having at least one recess 221 and at least one protrusion 222. In embodiments where the track forming portion 20 has two or more recesses 221 and two or more protrusions 222, these recesses 221 and protrusions 222 of the track forming portion 20 are arranged alternately, as shown in the attached figure. Figure 7 The track forming part 20 is disposed on the bottom shell 10.

[0064] The headgear assembly 30 is movably mounted on the bottom shell 10. The bottom of the reset element 40 abuts against the bottom shell 10, and the top of the reset element 40 abuts against the bottom of the headgear assembly 30. When the headgear assembly 30 is pressed downward, the headgear assembly 30 compresses the reset element 40 towards the bottom shell 10, causing the reset element 40 to be compressed and deformed, accumulating elastic potential energy. When the headgear assembly 30 is released, the reset element 40 pushes the headgear assembly 30 upward during the process of returning to its initial state. In this invention, the reset element 40 is a compression spring, such as, but not limited to, a compression spring made of metal. In other examples, the reset element 40 may also be a plastic spring. The headgear assembly 30 has a headgear cavity 31, at least one top balm outlet 32, and a bottom channel 33, the top balm outlet 32 ​​and the bottom channel 33 respectively communicating with the headgear cavity 31.

[0065] The bottle assembly 50 includes a bottle body 51, a piston 52, and a threaded post 53. The bottle body 51 includes an inner bottle 511 and a driven post 512.

The driven post 512 has at least one protrusion 5121, at least one thread 5122, and a column channel 5123. The driven post 512 extends downward from the inner bottle 511. The column channel 5123 of the driven post 512 communicates with the cavity 5111 of the inner bottle 511. The thread 5122 is disposed on the inner wall of the driven post 512, causing the thread 5122 to protrude into the column channel 5123. Preferably, the inner bottle 511 and the driven post 512 are integral, with the driven post 512 extending downward from the bottom of the inner bottle 511. Optionally, the top of the driven column 512 is fixedly mounted to the inner bottle 511.

[0066] The piston 52 is movably mounted vertically in the cavity 5111 of the inner bottle 511, and the piston 52 is used to support the paste 100. The top of the threaded post 53 is rotatably mounted on the piston 52, the bottom of the threaded post 53 extends into the column channel 5123 of the driven post 512, and the thread 5122 of the driven post 512 extends into the thread groove 531 of the threaded post 53.

[0067] In this invention, the inner bottle 511 has at least one first guide post 5113 extending along the height direction. The piston 52 has at least one first guide groove 521 on its periphery. The first guide post 5113 of the inner bottle 511 protrudes into the first guide groove 521 of the piston 52. The first guide post 5113 of the inner bottle 511 and the first guide groove 521 of the piston 52 cooperate to ensure that the piston 52 can only move relative to the inner bottle 511 in the height direction, and will not rotate relative to the inner bottle 511. Preferably, the number of first guide posts 5113 of the inner bottle 511 and the number of first guide grooves 521 of the piston 52 are both two. Preferably, the bottom of the piston 52 has a piston groove 522, and the top of the threaded post 53 extends into the piston groove 522 of the piston 52.

[0068] The inner bottle 511 of the bottle body 51 is rotatably mounted in the cap cavity 31 of the cap assembly 30. The cap assembly 30 closes the bottle opening 5112 of the inner bottle 511. The top outlet 32 ​​of the cap assembly 30 connects the bottle cavity 5111 of the inner bottle 511 with the external environment. The bottom of the driven column 512 extends into the column hole 21 of the track forming part 20 after passing through the bottom channel 33 of the cap assembly 30. The column protrusion 5121 of the driven column 512 protrudes into the track groove 22 of the track forming part 20. The threaded column 53 is movably mounted on the track forming part 20.

[0069] When the user presses the cap assembly 30, the cap assembly 30 and the bottle assembly 50 move downward synchronously. During this process, on the one hand, the reset element 40 is compressed and deformed to accumulate elastic potential energy. On the other hand, as the column protrusion 5121 of the driven column 512 of the bottle 51 slides from the protrusion 222 to the recess 221 in the track groove 22 of the track forming part 20, the bottle 51 and the piston 52 rotate relative to the cap assembly 30. At the same time, as the thread 5122 of the driven column 512 slides in the thread groove 531 of the threaded column 53, the threaded column 53 moves upward and pushes the piston 52 to move upward synchronously. Thus, the ointment 100 supported by the piston 52 is taken out through the top ointment outlet 32 ​​of the cap assembly 30. When the user releases the cap assembly 30, the reset element 40 pushes the cap assembly 30 and the bottle assembly 50 upward synchronously during the process of restoring the initial state. During this process, as the protrusion 5121 of the driven post 512 of the bottle 51 slides from the recess 221 to the protrusion 222 in the track groove 22 of the track forming part 20, the bottle 51 and the piston 52 rotate relative to the cap assembly 30. At the same time, as the thread 5122 of the driven post 512 slides in the thread groove 531 of the threaded post 53, the threaded post 53 moves upward and pushes the piston 52 upward synchronously. Thus, the ointment 100 supported by the piston 52 is taken out through the top ointment outlet 32 ​​of the cap assembly 30.

[0070] Unlike existing technologies, in the press-type cream jar of this embodiment, firstly, the user can take the cream 100 contained in the bottle cavity 5111 of the inner bottle 511 and supported by the piston 52 by pressing the cap assembly 30 with one hand, making the press-type cream jar of the present invention more convenient to operate and more widely applicable; secondly, since the track groove 22 of the track forming part 20 is preset, the distance the piston 52 moves upward is fixed each time the user presses and releases the cap assembly 30, and the user can quantitatively take the cream 100 by controlling the number of times the cap assembly 30 is pressed and released.

[0071] Further, see attached document. Figure 5The headgear assembly 30 has a top ointment outlet 32 ​​having a first opening edge 321, a second opening edge 322, and an ointment dispensing channel 323. The first opening edge 321 and the second opening edge 322 correspond to each other to form the ointment dispensing channel 323 between the first opening edge 321 and the second opening edge 322. The headgear assembly 30 also has at least one spatula 34, which is provided to extend from the first opening edge 321 toward the second opening edge 322, and the height of the side of the spatula 34 adjacent to the first opening edge 321 is lower than the height of the second opening edge 322. When the user presses and releases the cap assembly 30, as the bottle 51 and the piston 52 rotate, the spatula 34 can scoop up the cream 100. The scooped-up cream 100 enters the cream outlet 323 of the top cream outlet 32 ​​along the spatula 34, and is discharged to the top surface of the cap assembly 30 through the cream outlet 323 for the user to use.

[0072] In the appendix Figures 1 to 12 In this specific example of the press-type cream jar of the present invention shown, the number of the top dispensing nozzles 32 and the number of spatulas 34 of the cap assembly 30 are both two.

[0073] In this embodiment, refer to the appendix Figure 2 , Figure 3 and Figure 7 The bottom shell 10 has a bottom shell cavity 11 and a cavity opening 12 communicating with the bottom shell cavity 11. The track forming part 20 is disposed at the bottom of the bottom shell cavity 11 of the bottom shell 10. The reset element 40 is located in the bottom shell cavity 11 of the bottom shell 10. The bottom of the headgear assembly 30 extends into the bottom shell cavity 11 of the bottom shell 10 through the cavity opening 12 of the bottom shell 10. In this way, the track forming part 20 and the reset element 40 are hidden between the bottom shell 10 and the headgear assembly 30.

[0074] Furthermore, the headgear assembly 30 includes a headgear 35 and a bottom cover 36. The bottom cover 36 is installed at the bottom of the headgear 35 to form the headgear cavity 31 of the headgear assembly 30 between the headgear 35 and the bottom cover 36. The top ointment outlet 32 ​​and the spatula 34 of the headgear assembly 30 are disposed on the headgear 35. The bottom channel 33 of the headgear assembly 30 is formed in the bottom cover 36.

[0075] Specifically, the cap 35 has a cap plate 351 and a cap wall 352, the cap wall 352 extending downward from the cap plate 351 to form a cap cavity 353 between the cap plate 351 and the cap wall 352. The top ointment outlet 32 ​​and the spatula 34 of the cap assembly 30 are disposed on the cap plate 351 of the cap 35. The bottom cover 36 includes a bottom cover plate 361 and a bottom cover wall 362 extending downward from the bottom cover plate 361 to form a bottom cover cavity 363 between the bottom cover plate 361 and the bottom cover wall 362. The bottom channel 33 of the cap assembly 30 is disposed on the bottom cover plate 361. The inner diameter of the head cap cavity 353 of the head cap 35 is the same as the outer diameter of the bottom cover wall 362 of the bottom cover 36. Thus, when the top of the bottom cover 36 extends into the head cap cavity 353 of the head cap 35, the outer wall of the bottom cover wall 362 of the bottom cover 36 fits against the inner wall of the cap wall 352 of the head cap 35. The bottom cover 36 is thus installed on the head cap 35, and the head cap cavity 353 of the head cap 35 forms the head cap cavity 31 of the head cap assembly 30.

[0076] To prevent the cap 35 and the bottom cover 36 from rotating relative to each other, in this embodiment, refer to the attached... Figures 3 to 5 The bottom of the inner wall of the cap 352 of the cap 35 is provided with at least one first retaining rib 3521, and the top of the bottom cover wall 362 of the bottom cover 36 is provided with at least one first retaining groove 3621. After the top of the bottom cover 36 extends into the cap cavity 353 of the cap 35, the first retaining rib 3521 of the cap 352 of the cap 35 is engaged with the first retaining groove 3621 of the bottom cover wall 362 of the bottom cover 36.

[0077] Additionally, please refer to the appendix. Figure 2 and Figure 3 The bottom cover 36 has a retaining ring 3622 on its bottom cover wall 362. When the top of the bottom cover 36 is inserted into the head cap cavity 353 of the head cap 35, the bottom of the head cap wall 352 of the head cap 35 can abut against the retaining ring 3622 of the bottom cover wall 36 of the bottom cover 36, so as to control the depth at which the bottom cover 36 is installed in the head cap 35.

[0078] Continue to refer to the appendix Figures 2 to 5The inner bottle 511 has an annular second retaining rib 5114, and the cap wall 352 of the cap 35 is provided with an annular second retaining groove 3522. The second retaining rib 5114 of the inner bottle 511 is engaged with the second retaining groove 3522 of the cap wall 352. In this way, on the one hand, when the user presses the cap assembly 30, the inner bottle 511 can rotate relative to the cap 35, and on the other hand, the cap 35 and the inner bottle 511 will not have relative displacement in the height direction.

[0079] Furthermore, the bottom cover 36 has at least one second guide post 364 extending along the height direction, and the bottom shell 10 has at least one second guide groove 13 extending along the height direction. The second guide post 364 of the bottom cover 36 protrudes into the second guide groove 13 of the bottom shell 10, thereby allowing the headgear assembly 30 to be movably mounted on the bottom shell 10. When the user presses and releases the headgear assembly 30, the second guide post 364 of the bottom cover 36 and the second guide groove 13 of the bottom shell 10 cooperate to ensure that the headgear assembly 30 can only move relative to the bottom shell 10 along the height direction, and will not rotate relative to the bottom shell 10. Optionally, in other examples, the second guide post 364 may be provided on the bottom shell 10, and the second guide groove 13 may be provided on the bottom cover 36. The second guide post 364 of the bottom shell 10 protrudes into the second guide groove 13 of the bottom cover 36. When the user presses and releases the headgear assembly 30, the second guide post 364 of the bottom shell 10 and the second guide groove 13 of the bottom cover 36 cooperate with each other, so that the headgear assembly 30 can only move relative to the bottom shell 10 in the height direction, and will not rotate relative to the bottom shell 10.

[0080] Specifically, see the attached document. Figure 2 , Figure 3 and Figure 7The bottom shell 10 includes a bottom shell plate 14, a bottom shell wall 15, and a bottom shell ring 16. The bottom shell wall 15 extends upward from the periphery of the bottom shell plate 14 to form the bottom shell cavity 11 between the bottom shell plate 14 and the bottom shell wall 15, and the bottom shell wall 15 defines the cavity opening 12 of the bottom shell 10. The bottom shell ring 16 extends upward from the middle of the bottom shell plate 14, and the bottom shell wall 15 surrounds the bottom shell ring 16. The second guide groove 13 of the bottom shell 10 is provided in the bottom shell ring 16. The second guide post 364 of the bottom cover 36 is disposed on the bottom cover wall 362 and protrudes into the bottom cover cavity 363. The outer diameter of the bottom shell ring 16 is the same as the inner diameter of the bottom cover cavity 363 of the bottom cover 36. The bottom shell ring 16 extends into the bottom cover cavity 363 of the bottom cover 36 so that the second guide post 364 of the bottom cover 36 protrudes into the second guide groove 13 of the bottom shell 10 and prevents the bottom shell 10 and the bottom cover 36 from shaking, thereby allowing the headgear assembly 30 to be movably mounted on the bottom shell 10.

[0081] In the appendix Figures 1 to 12 In this specific example of the press-type cream jar of the present invention shown, the number of the second guide posts 364 of the bottom cover 36 is multiple, and correspondingly, the number of the second guide grooves 13 of the bottom shell 10 is multiple, with each of the second guide posts 364 of the bottom cover 36 protruding into each of the second guide grooves 13 of the bottom shell 10.

[0082] In this invention, reference is made to the appendix. Figure 4 and Figure 6 The bottom of the driven post 512 of the bottle body 51 has at least one elastic arm 5124, and the column protrusion 5121 is located on the outer wall of the elastic arm 5124. When assembling the press-type cream jar, firstly, the column protrusion 5121 of the driven post 512 of the bottle body 51 is allowed to rest against the edge of the top opening of the column hole 21 of the track forming part 20. Secondly, when the bottle body 51 is pressed down, the end of the column protrusion 5121 is squeezed, causing the elastic arm 5124 to deform, so as to allow the column protrusion 5121 to slide into the column hole 21 of the track forming part 20. When the column protrusion 5121 slides down to the position corresponding to the track groove 22, the elastic arm 5124 pushes the column protrusion 5121 outward during the process of returning to the initial state, so that the column protrusion 5121 protrudes into the track groove 22 of the track forming part 20.

[0083] Preferably, the top opening of the column hole 21 of the track forming part 20 is provided with an inclined guide surface 23 for guiding the column protrusion 5121 of the driven column 512 to slide into the column hole 21.

[0084] Preferably, the bottom of the driven post 512 of the bottle body 51 has two elastic arms 5124 and two column protrusions 5121. The two elastic arms 5124 are symmetrical to each other, and the two column protrusions 5121 are symmetrical to each other. In this way, when the cap assembly 30 is pressed, the driven post 512 of the bottle body 51 can be subjected to force evenly and avoid tilting.

[0085] Further, see attached document. Figures 2 to 4 , Figure 7 The track forming part 20 includes a base ring 24 and a top cover ring 25. The base ring 24 is disposed on the bottom shell 10, and the base ring 24 and the top cover ring 25 are mounted to each other to form the track groove 22 between the base ring 24 and the top cover ring 25. A portion of the post hole 21 of the track forming part 20 is formed in the top cover ring 25, and another portion is formed in the base ring 24.

[0086] Preferably, the track forming part 20 further includes an insertion post 26, the base ring 24 surrounds the insertion post 26, the insertion post 26 has at least one third guide post 261, the third guide post 261 extends along the height direction, the threaded post 53 has a column hole 532 and at least one third guide groove 533, the third guide groove 533 is provided on the inner wall of the threaded post 53 for defining the column hole 532 and extends along the height direction, wherein the insertion post 26 is inserted into the column hole 532 of the threaded post 53, and the third guide post 261 of the insertion post 26 protrudes into the third guide groove 533 of the threaded post 53, so that the threaded post 53 is movably mounted on the track forming part 20, and the threaded post 53 is prevented from rotating when the head cap assembly 30 is pressed. Optionally, in other examples of the present invention, the third guide post 261 may be provided on the threaded post 53 and protrude into the post hole 532 of the threaded post 53. Correspondingly, the third guide groove 533 may be provided on the insertion post 26. The insertion post 26 is inserted into the post hole 532 of the threaded post 53, and the third guide post 261 of the threaded post 53 protrudes into the third guide groove 533 of the insertion post 26, so that the threaded post 53 is movably mounted on the track forming part 20, and the threaded post 53 is prevented from rotating when the head cap assembly 30 is pressed.

[0087] In the appendix Figures 1 to 12In this specific example of the press-type cream jar of the present invention shown, the number of the third guide posts 261 of the insertion post 26 of the track forming part 20 is multiple, the number of the third guide grooves 533 of the threaded post 53 is multiple, and each of the third guide posts 261 of the insertion post 26 protrudes into each of the third guide grooves 533 of the threaded post 53.

[0088] Preferably, in this invention, the base ring 24, the insertion post 26, and the bottom shell 10 are integrally formed. For example, the bottom shell 10, the base ring 24, and the insertion post 26 can be integrally formed from plastic material by means of injection molding process, so as to simplify the structure of the press-type cream jar.

[0089] In this embodiment, refer to the appendix Figure 3 , Figure 4 and Figure 7 The base ring 24 has a plurality of first protrusions 241 and a plurality of first grooves 242 on its top. These first protrusions 241 and first grooves 242 are arranged alternately, that is, there is one first groove 242 between two adjacent first protrusions 241 and one first protrusion 241 between two adjacent first grooves 242. The top cover ring 25 includes a cover ring body 251 and a track ring 252 disposed on the top of the inner wall of the cover ring body 251. The bottom of the track ring 252 has a plurality of second protrusions 2521 and a plurality of second grooves 2522. These first protrusions 2521 and second grooves 2522 are arranged alternately, that is, there is one second groove 2522 between two adjacent second protrusions 2521 and one second protrusion 2521 between two adjacent second grooves 2522. After the top cap ring 25 is installed on the base ring 24, the top of the base ring 24 is located below the bottom of the track ring 252. One of the second protrusions 2521 and the adjacent second groove 2522 of the track ring 252 correspond to different positions of the first groove 242 of the base ring 24. In this way, when the cap assembly 30 is pressed and released, the bottle 51 can only rotate in one direction to ensure that the user can take a measured amount of the ointment 100.

[0090] In this embodiment, the outer wall of the base ring 24 has at least one first positioning strip 243 and at least one second positioning strip 244. The first positioning strip 243 extends along the circumferential direction, and the second positioning strip 244 extends along the height direction. Correspondingly, the inner wall of the cover ring body 251 of the top cover ring 25 has at least one first positioning groove 2511 and at least one second positioning groove 2512. The first positioning groove 2511 extends along the circumferential direction, and the second positioning groove 2512 extends along the height direction. After the top of the base ring 24 is inserted into the interior of the cover ring body 251, the first positioning strip 243 and the second positioning strip 244 of the base ring 24 protrude into the first positioning groove 2511 and the second positioning groove 2512 of the cover ring body 251, respectively, to reliably install the top cover ring 25 and the base ring 24. At this time, the base ring 24 and the top cover ring 25 are fixedly installed, and neither will rotate relative to the other nor will they have relative displacement in the height direction.

[0091] Specifically, the top of the base ring 24 has multiple inclined first support surfaces 245 and multiple inclined second support surfaces 246. Each of the opposite ends of any one of the first support surfaces 245 is connected to a second support surface 246, and each of the opposite ends of any one of the second support surfaces 246 is connected to a first support surface 245. A first protrusion 241 is formed between one of the first support surfaces 245 and an adjacent second support surface 246, and a first groove 242 is formed between another adjacent second support surface 246. The angle between the first support surface 245 and the horizontal plane is smaller than the angle between the second support surface 246 and the horizontal plane. The bottom of the track ring 252 of the top cover ring 25 has a plurality of inclined first abutment surfaces 2523 and a plurality of inclined second abutment surfaces 2524. Each of the opposite ends of any one of the first abutment surfaces 2523 is connected to a second abutment surface 2524, and each of the opposite ends of any one of the second abutment surfaces 2524 is connected to a first abutment surface 2523. A second protrusion 2521 is formed between one of the first abutment surfaces 2523 and an adjacent second abutment surface 2524, and a second groove 2522 is formed between another adjacent second abutment surface 2524. The included angle between the first abutment surface 2523 and the horizontal plane is smaller than the included angle between the second abutment surface 2524 and the horizontal plane. The projection of the second abutment surface 2524 of the track ring 252 of the top cap ring 25 onto the horizontal plane is included within the projection of the first support surface 245 of the base ring 24 onto the horizontal plane. In this way, one of the second protrusions 2521 and the adjacent second groove 2522 of the track ring 252 correspond to different positions of the first groove 242 of the base ring 24. Therefore, when the cap assembly 30 is pressed and released, the bottle 51 can only rotate in one direction, ensuring that the user can dispense a measured amount of the cream 100. That is, one of the second protrusions 2521 and the adjacent second groove 2522 of the track ring 252 of the top cap ring 25 are located above the first support surface 245 of the base ring 24, so that when the user presses and releases the cap assembly 30, the bottle 51 can only rotate in one direction, ensuring that the user can dispense a measured amount of the cream 100.

[0092] Further, see attached document. Figures 2 to 4The press-type cream jar includes a shoulder sleeve 60, which is fitted onto the outside of the cap 35 and fixedly installed on the bottom shell 10. The shoulder sleeve 60 reduces the gap between the bottom shell 10 and the cap 35, thereby improving the aesthetics of the press-type cream jar. Preferably, the shoulder sleeve 60 has at least one second retaining rib 61, and the bottom shell wall 15 of the bottom shell 10 has at least one second retaining groove 151. The second retaining rib 61 of the shoulder sleeve 60 is engaged with the second retaining groove 151 of the bottom shell wall 15 of the bottom shell 10 to securely install the shoulder sleeve 60 onto the bottom shell 10. Preferably, the shoulder sleeve 60 has an abutment ring 62, which is fitted onto the top edge of the bottom shell wall 151 of the bottom shell 10.

[0093] Continue to refer to the appendix Figures 1 to 4 The press-type cream jar further includes a lid 70, which is detachably mounted on the shoulder sleeve 60. When the lid 70 is mounted on the shoulder sleeve 60, it covers the head cap 35. After the lid 70 is removed from the shoulder sleeve 60, the head cap 35 is exposed. Preferably, the shoulder sleeve 60 has at least one third retaining rib 63, and the lid 70 has at least one third retaining groove 71. When the lid 70 is mounted on the shoulder sleeve 60, the third retaining rib 63 of the shoulder sleeve 60 is engaged with the third retaining groove 71 of the lid 70, preventing the lid 70 from automatically detaching from the shoulder sleeve 60.

[0094] Appendix Figures 8 to 12The use of the press-type cream jar is illustrated. Specifically, when the cap assembly 30 is not pressed, under the action of the reset element 40, the protrusion 5121 of the driven post 512 of the bottle body 51 is held in the second groove 2522 of the cap ring body 251 of the top cap ring 25. When the user presses the cap assembly 30, the cap assembly 30 and the bottle assembly 50 move downwards synchronously. During this process, on the one hand, the reset element 40 is compressed and deformed to accumulate elastic potential energy. On the other hand, the protrusion 5121 of the driven post 512 slides along the first support surface 245 of the base ring 24 towards the first groove 242 of the base ring 24. The bottle 51 and the piston 52 rotate counterclockwise relative to the cap assembly 30. At the same time, as the thread 5122 of the driven post 512 slides in the thread groove 531 of the threaded post 53, the threaded post 53 moves upward and pushes the piston 52 to move upwards synchronously. Thus, the ointment 100 supported by the piston 52 is scooped up by the spatula 34 and discharged through the top ointment outlet 32 ​​of the cap assembly 30. When the user releases the cap assembly 30, the reset element 40 pushes the cap assembly 30 and the bottle assembly 50 upward synchronously during the process of restoring the initial state. During this process, the protrusion 5121 of the driven post 512 slides along the first abutting surface 2523 of the track ring 252 of the top cover ring 25 towards the second groove 2522 of the track ring 252. The bottle 51 and the piston 52 rotate counterclockwise relative to the cap assembly 30. At the same time, as the thread 5122 of the driven post 512 slides in the thread groove 531 of the threaded post 53, the threaded post 53 moves upward and pushes the piston 52 upward synchronously. Thus, the ointment 100 supported by the piston 52 is scooped up by the spatula 34 and discharged through the top ointment outlet 32 ​​of the cap assembly 30. It is understood that the specific arrangement of the base ring 24 and the top cap ring 25 ensures that each time the user presses and releases the cap assembly 30, the bottle body 51 and the piston 52 will only rotate in a counterclockwise direction. Therefore, the amount of cream 100 discharged each time the user presses and releases the cap assembly 30 is fixed, thereby achieving quantitative dispensing of the cream 100.

[0095] Appendix Figures 13 to 23 A press-type cream jar according to another preferred embodiment of the present invention is shown. The press-type cream jar includes a bottom shell 10A, a track forming part 20A, a cap assembly 30A, a reset element 40A, and a bottle body assembly 50A.

[0096] Specifically, the track forming portion 20A has a post hole 21A and a track groove 22A, the track groove 22A having at least one recess 221A and at least one protrusion 222A. In embodiments where the track forming portion 20A has two or more recesses 221A and two or more protrusions 222A, these recesses 221A and protrusions 222A are arranged alternately. The track forming portion 20A is disposed on the bottom shell 10A.

[0097] The headgear assembly 30A is movably mounted on the bottom shell 10A. The bottom of the reset element 40A abuts against the bottom shell 10A, and the top of the reset element 40A abuts against the bottom of the headgear assembly 30A. When the headgear assembly 30A is pressed downward, it compresses the reset element 40A towards the bottom shell 10A, causing the reset element 40A to be compressed and deformed, accumulating elastic potential energy. When the headgear assembly 30A is released, the reset element 40A pushes the headgear assembly 30A upward as it returns to its initial state. In this invention, the reset element 40A is a compression spring, such as, but not limited to, a metal compression spring. In other examples, the reset element 40A may also be a plastic spring. The headgear assembly 30A has a headgear cavity 31A, at least one top balm outlet 32A, and a bottom channel 33A, wherein the top balm outlet 32A and the bottom channel 33A are respectively connected to the headgear cavity 31A.

[0098] The bottle assembly 50A includes a bottle body 51A, which includes an inner bottle 511A and a driven column 512A. The inner bottle 511A has a cavity 5111A and a bottle opening 5112A communicating with the cavity 5111A. The driven column 512A has at least one column protrusion 5121A and a column channel 5123A. The driven column 512A extends downward from the inner bottle 511A, and the column channel 5123A of the driven column 512A communicates with the cavity 5111A of the inner bottle 511A. Preferably, the inner bottle 511A and the driven column 512A are integral, and the driven column 512A extends downward from the bottom of the inner bottle 511A. Optionally, the top of the driven column 5121A is fixedly mounted to the bottom of the inner bottle 511A.

[0099] The bottle assembly 50A includes a drive sleeve 54A, which has a sleeve channel 541A and at least one thread 542A. The thread 542A protrudes into the sleeve channel 541A. The drive sleeve 54A is rotatably mounted to the column channel 5123A of the driven column 512A, allowing the drive sleeve 54A and the bottle 51A to rotate relative to each other. The drive sleeve 54A is also movably mounted to the track forming portion 20A, allowing the drive sleeve 54A and the track forming portion 20A to move relative to each other in the height direction. Preferably, the drive sleeve 54A has three threads 542A.

[0100] The bottle assembly 50A includes a piston 52A and a threaded post 53A. The piston 52A is movably mounted vertically in the bottle cavity 5111A of the inner bottle 511A, and the piston 52A supports the ointment 100A. The top of the threaded post 53A is fixedly disposed on the piston 52A, the bottom of the threaded post 53A extends into the sleeve channel 541A of the drive sleeve 54A, and the threads 542A of the drive sleeve 54A extend into the threaded groove 531A of the threaded post 53A. (See attached...) Figures 13 to 23 In the example shown, the threaded post 53A and the piston 52A are integral, such that the top of the threaded post 53A is fixedly disposed on the piston 52A. Alternatively, in other examples, the top of the threaded post 53A is fixedly mounted on the piston 52A.

[0101] In this invention, the inner bottle 511A has at least one first guide post 5113A, which extends along the height direction. The piston 52A has at least one first guide groove 521A on its periphery. The first guide post 5113A of the inner bottle 511A protrudes into the first guide groove 521A of the piston 52A. The first guide post 5113A of the inner bottle 511A and the first guide groove 521A of the piston 52A cooperate to ensure that the piston 52A can only move relative to the inner bottle 511A in the height direction, and will not rotate relative to the inner bottle 511A. Preferably, the number of first guide posts 5113A of the inner bottle 511A and the number of first guide grooves 521A of the piston 52A are both two.

[0102] The inner bottle 511A of the bottle body 51A is rotatably mounted in the cap cavity 31A of the cap assembly 30A. The cap assembly 30A closes the bottle opening 5112A of the inner bottle 511A. The top outlet 32A of the cap assembly 30A connects the bottle cavity 5111A of the inner bottle 511A with the external environment. The bottom of the driven column 512A extends into the column hole 21A of the track forming part 20A after passing through the bottom channel 33A of the cap assembly 30A. The column protrusion 5121A of the driven column 512A protrudes into the track groove 22A of the track forming part 20A.

[0103] When the user presses the cap assembly 30A, the cap assembly 30A and the bottle assembly 50A move downwards synchronously. During this process, on the one hand, the reset element 40A is compressed and deformed to accumulate elastic potential energy. On the other hand, as the protrusion 5121A of the driven post 512A of the bottle body 51A slides from the protrusion 222A to the recess 221A in the track groove 22A of the track forming part 20A, the bottle body 51A and the piston 52A rotate relative to the cap assembly 30A. At the same time, as the thread 542A of the drive sleeve 54A slides in the thread groove 531A of the threaded post 53A, the threaded post 53A moves upward and pushes the piston 52A to move upwards synchronously. Thus, the ointment 100A supported by the piston 52A is taken out through the top ointment outlet 32A of the cap assembly 30A. When the user releases the cap assembly 30A, the reset element 40A pushes the cap assembly 30A and the bottle assembly 50A upward synchronously during the process of restoring the initial state. During this process, as the protrusion 5121A of the driven post 512A of the bottle 51A slides from the recess 221A to the protrusion 222A in the track groove 22A of the track forming part 20A, the bottle 51A and the piston 52A rotate relative to the cap assembly 30A. At the same time, as the thread 542A of the drive sleeve 54A slides in the thread groove 531A of the threaded post 53A, the threaded post 53A moves upward and pushes the piston 52A upward synchronously. Thus, the ointment 100A supported by the piston 52A is taken out through the top ointment outlet 32A of the cap assembly 30A.

[0104] Unlike existing technologies, in the press-type cream jar of this embodiment, firstly, the user can take the cream 100A contained in the bottle cavity 5111A of the inner bottle 511A and supported by the piston 52A by pressing the cap assembly 30A with one hand, making the press-type cream jar of the present invention more convenient to operate and more widely applicable; secondly, since the track groove 22A of the track forming part 20A is preset, the distance that the piston 52A moves upward is fixed each time the user presses and releases the cap assembly 30A, and the user can quantitatively take the cream 100A by controlling the number of times the cap assembly 30A is pressed and released.

[0105] Preferably, the top of the drive sleeve 54A has an abutment ring 543A, the middle part of the drive sleeve 54A has a first hook ring 544A, the middle part of the driven column 512A has a second hook ring 5124A, the second hook ring 5124A protrudes into the column channel 5123A, the abutment ring 543A of the drive sleeve 54A is abutted against the bottom of the inner bottle 511A, the first hook ring 544A of the drive sleeve 54A is located below the second hook ring 5124A of the driven column 512A, and the first hook ring 544A of the drive sleeve 54A and the second hook ring 5124A of the driven column 512A hook each other, so that the drive sleeve 54A and the inner bottle 511A can only rotate relative to each other, and will not be displaced in the height direction.

[0106] Further, see attached document. Figure 16 The headgear assembly 30A has a top cream dispensing port 32A with a first opening edge 321A, a second opening edge 322A, and a cream dispensing channel 323A. The first opening edge 321A and the second opening edge 322A correspond to each other to form the cream dispensing channel 323A between the first opening edge 321A and the second opening edge 322A. The headgear assembly 30A also has at least one spatula 34A, which is provided to extend from the first opening edge 321A toward the second opening edge 322A, and the height of the side of the spatula 34A adjacent to the first opening edge 321A is lower than the height of the second opening edge 322A. When the user presses and releases the cap assembly 30A, as the bottle body 51A and the piston 52A rotate, the spatula 34A can scoop up the cream 100A. The scooped-up cream 100A enters the cream outlet 323A through the spatula 34A into the cream outlet channel 323A at the top, and is discharged through the cream outlet channel 323A to the top surface of the cap assembly 30A for the user to use.

[0107] In the appendix Figures 13 to 23In this specific example of the press-type cream jar of the present invention shown, the number of the top dispensing port 32A of the cap assembly 30A and the number of the spatula 34A are both two.

[0108] In this embodiment, refer to the appendix Figure 13 , Figure 14 and Figure 18 The bottom shell 10A has a bottom shell cavity 11A and a cavity opening 12A communicating with the bottom shell cavity 11A. The track forming part 20A is disposed at the bottom of the bottom shell cavity 11A of the bottom shell 10A. The reset element 40A is located in the bottom shell cavity 11A of the bottom shell 10A. The bottom of the headgear assembly 30A extends into the bottom shell cavity 11A of the bottom shell 10A through the cavity opening 12A of the bottom shell 10A. In this way, the track forming part 20A and the reset element 40A are hidden between the bottom shell 10A and the headgear assembly 30A.

[0109] Furthermore, the cap assembly 30A includes a cap 35A and a bottom cover 36A. The bottom cover 36A is installed at the bottom of the cap 35A to form the cap cavity 31A of the cap assembly 30A between the cap 35A and the bottom cover 36A. The top ointment outlet 32A and the spatula 34A of the cap assembly 30A are disposed on the cap 35A. The bottom channel 33A of the cap assembly 30A is formed in the bottom cover 36A.

[0110] Specifically, the cap 35A has a cap plate 351A and a cap wall 352A. The cap wall 352A extends downward from the cap plate 351A to form a cap cavity 353A between the cap plate 351A and the cap wall 352A. The top ointment outlet 32A and the spatula 34A of the cap assembly 30A are disposed on the cap plate 351A of the cap 35A. The bottom cover 36A includes a bottom cover plate 361A and a bottom cover wall 362A extending downward from the bottom cover plate 361A to form a bottom cover cavity 363A between the bottom cover plate 361A and the bottom cover wall 362A. The bottom channel 33A of the cap assembly 30A is disposed on the bottom cover plate 361A. The inner diameter of the head cap cavity 353A of the head cap 35A is the same as the outer diameter of the bottom cover wall 362A of the bottom cover 36A. Thus, when the top of the bottom cover 36A extends into the head cap cavity 353A of the head cap 35A, the outer wall of the bottom cover wall 362A of the bottom cover 36A fits against the inner wall of the cap wall 352A of the head cap 35A. The bottom cover 36A is thus installed on the head cap 35A, and the head cap cavity 353A of the head cap 35A forms the head cap cavity 31A of the head cap assembly 30A.

[0111] To prevent the head cap 35A and the bottom cover 36A from rotating relative to each other, in this embodiment, refer to the attached... Figures 13 to 15 The bottom of the inner wall of the cap 35A of the head cap 35A is provided with at least one first retaining rib 3521A, and the top of the bottom cover wall 362A of the bottom cover 36A is provided with at least one first retaining groove 3621A. After the top of the bottom cover 36A extends into the head cap cavity 353A of the head cap 35A, the first retaining rib 3521A of the cap 35A of the cap 35A is engaged with the first retaining groove 3621A of the bottom cover wall 362A of the bottom cover 36A.

[0112] Additionally, please refer to the appendix. Figures 13 to 15 The bottom cover 36A has a retaining ring 3622A on its bottom cover wall 362A. When the top of the bottom cover 36A is inserted into the head cap cavity 353A of the head cap 35A, the bottom of the head cap wall 352A of the head cap 35A can abut against the retaining ring 3622A of the bottom cover wall 362A of the bottom cover 36A to control the depth at which the bottom cover 36A is installed in the head cap 35A.

[0113] Continue to refer to the appendix Figures 13 to 16 The inner bottle 511A has an annular second retaining rib 5114A, and the cap wall 352A of the cap 35A is provided with an annular second retaining groove 3522A. The second retaining rib 5114A of the inner bottle 511A is engaged with the second retaining groove 3522A of the cap wall 352A. In this way, on the one hand, when the user presses the cap assembly 30A, the inner bottle 511A can rotate relative to the cap 35A. On the other hand, the cap 35A and the inner bottle 511A will not have relative displacement in the height direction.

[0114] Furthermore, the bottom cover 36A has at least one second guide post 364A extending along the height direction, and the bottom shell 10A has at least one second guide groove 13A extending along the height direction. The second guide post 364A of the bottom cover 36A protrudes into the second guide groove 13A of the bottom shell 10A, thereby allowing the headgear assembly 30A to be movably mounted on the bottom shell 10A. When the user presses and releases the headgear assembly 30A, the second guide post 364A of the bottom cover 36A and the second guide groove 13A of the bottom shell 10A cooperate with each other, allowing the headgear assembly 30A to move only along the height direction relative to the bottom shell 10A, without rotating relative to the bottom shell 10A. Preferably, in the attached... Figures 13 to 23In one embodiment, a pair of second guide posts 364A of the bottom cover 36A are located within the same second guide groove 13A of the bottom shell 10A. Optionally, in other examples, the second guide posts 364A may be provided on the bottom shell 10A, and the second guide groove 13A may be provided on the bottom cover 36A. The second guide posts 364A of the bottom shell 10A protrude into the second guide groove 13A of the bottom cover 36A. When the user presses and releases the headgear assembly 30A, the second guide posts 364A of the bottom shell 10A and the second guide groove 13A of the bottom cover 36A cooperate with each other, so that the headgear assembly 30A can only move relative to the bottom shell 10A along the height direction, and will not rotate relative to the bottom shell 10A.

[0115] Specifically, see the attached document. Figure 13 , Figure 14 and Figure 18 The bottom shell 10A includes a bottom shell plate 14A, a bottom shell wall 15A, and a bottom shell ring 16A. The bottom shell wall 15A extends upward from the periphery of the bottom shell plate 14A to form the bottom shell cavity 11A between the bottom shell plate 14A and the bottom shell wall 15A, and defines the cavity opening 12A of the bottom shell 10A by the bottom shell wall 15A. The bottom shell ring 16A extends upward from the middle of the bottom shell plate 14A, and the bottom shell wall 15A surrounds the bottom shell ring 16A. The second guide groove 13A of the bottom shell 10A is provided in the bottom shell ring 16A. The second guide post 364A of the bottom cover 36A is disposed on the bottom cover wall 362A and protrudes into the bottom cover cavity 363A. The outer diameter of the bottom shell ring 16A is the same as the inner diameter of the bottom cover cavity 363A of the bottom cover 36A. The bottom shell ring 16A extends into the bottom cover cavity 363A of the bottom cover 36A so that the second guide post 364A of the bottom cover 36A protrudes into the second guide groove 13A of the bottom shell 10A and prevents the bottom shell 10A and the bottom cover 36A from shaking, thereby allowing the headgear assembly 30A to be movably mounted on the bottom shell 10A.

[0116] In this invention, reference is made to the appendix. Figure 15 and Figure 17The bottom of the driven post 512A of the bottle body 51A has at least one elastic arm 5125A, and the column protrusion 5121A is located on the outer wall of the elastic arm 5125A. When assembling the press-type cream jar, firstly, the column protrusion 5121A of the driven post 512A of the bottle body 51A is allowed to rest against the edge of the top opening of the column hole 21A of the track forming part 20A. Secondly, when the bottle body 51A is pressed down, the column protrusion 5125A... The end of 121A is squeezed, causing the elastic arm 5125A to deform, so as to allow the protrusion 5121A to slide into the protrusion hole 21A of the track forming part 20A. When the protrusion 5121A slides down to the position corresponding to the track groove 22A, the elastic arm 5125A pushes the protrusion 5121A outward during the process of returning to the initial state, so that the protrusion 5121A protrudes into the track groove 22A of the track forming part 20A.

[0117] Preferably, the top opening of the column hole 21A of the track forming part 20A is provided with an inclined guide surface 23A for guiding the column protrusion 5121A of the driven column 512A to slide into the column hole 21A.

[0118] Preferably, the bottom of the driven post 512A of the bottle body 51A has four elastic arms 5125A and four column protrusions 5121A. In this way, when the cap assembly 30A is pressed, the driven post 512A of the bottle body 51A2 can be evenly stressed, avoiding tilting.

[0119] Further, see attached document. Figures 13 to 15 , Figure 18 The track forming part 20A includes a base ring 24A and a top cover ring 25A. The base ring 24A is disposed on the bottom shell 10A, and the base ring 24A and the top cover ring 25A are mounted to each other to form the track groove 22A between the base ring 24A and the top cover ring 25A. A portion of the post hole 21A of the track forming part 20A is formed in the top cover ring 25A, and another portion is formed in the base ring 24A.

[0120] Preferably, the track forming part 20A further includes an insertion post 26A, the base ring 24A surrounds the insertion post 26A, the insertion post 26A has at least one third guide post 261A and an insertion hole 262A, the third guide post 261A protrudes into the insertion hole 262A and extends along the height direction, the outer wall of the drive sleeve 54A has at least one third guide groove 545A, and the bottom of the drive sleeve 54A is movably mounted on the insertion post 26A such that the third guide post 261A protrudes into the third guide groove 545A, so that the drive sleeve 54A is movably mounted on the track forming part 20A, and the drive sleeve 54A is prevented from rotating when the headgear assembly 30A is pressed.

[0121] In the appendix Figures 13 to 23 In this specific example of the press-type cream jar of the present invention shown, the number of third guide posts 261A of the insertion post 26A of the track forming part 20A is multiple, the number of third guide grooves 545A of the drive sleeve 54A is multiple, and each of the third guide posts 261A of the insertion post 26A protrudes into each of the third guide grooves 545A of the drive sleeve 54A.

[0122] Preferably, in this invention, the base ring 24A, the insertion post 26A, and the bottom shell 10A are integrally formed. For example, the bottom shell 10A, the base ring 24A, and the insertion post 26A can be integrally formed from plastic material by means of injection molding process, so as to simplify the structure of the press-type cream jar.

[0123] In this embodiment, refer to the appendix Figures 13 to 15 , Figure 18The top of the base ring 24A has a plurality of first protrusions 241A and a plurality of first grooves 242A. These first protrusions 241A and first grooves 242A are arranged alternately, that is, there is one first groove 242A between two adjacent first protrusions 241A and one first protrusion 241A between two adjacent first grooves 242A. The top cover ring 25A includes a cover ring body 251A and a track ring 252A disposed on the top of the inner wall of the cover ring body 251A. The bottom of the track ring 252A has a plurality of second protrusions 2521A and a plurality of second grooves 2522A. These second protrusions 2521A and second grooves 2522A are arranged alternately, that is, there is one second groove 2522A between two adjacent second protrusions 2521A and one second protrusion 2521A between two adjacent second grooves 2522A. After the top cap ring 25A is installed on the base ring 24A, the top of the base ring 24A is located below the bottom of the track ring 252A. A second protrusion 2521A and an adjacent second groove 2522A of the track ring 252A correspond to different positions of the first groove 242A of the base ring 24A. In this way, when the cap assembly 30A is pressed and released, the bottle 51A can only rotate in one direction, so as to ensure that the user can take a measured amount of the ointment 100A.

[0124] In this embodiment, the outer wall of the base ring 24A has at least one first positioning strip 243A and at least one second positioning strip 244A. The first positioning strip 243A extends along the circumferential direction, and the second positioning strip 244A extends along the height direction. Correspondingly, the inner wall of the cover ring body 251A of the top cover ring 25A has at least one first positioning groove 2511A and at least one second positioning groove 2512A. The first positioning groove 2511A extends along the circumferential direction, and the second positioning groove 2512A extends along the height direction. After the top of the base ring 24A is inserted into the interior of the cover ring body 251A, the first positioning strip 243A and the second positioning strip 244A of the base ring 24A protrude into the first positioning groove 2511A and the second positioning groove 2512A of the cover ring body 251A, respectively, to reliably install the top cover ring 25A and the base ring 24A.

[0125] Specifically, the top of the base ring 24A has multiple inclined first support surfaces 245A and multiple inclined second support surfaces 246A. Each of the opposite ends of any one of the first support surfaces 245A is connected to a second support surface 246A, and each of the opposite ends of any one of the second support surfaces 246A is connected to a first support surface 245A. A first protrusion 241A is formed between one of the first support surfaces 245A and an adjacent second support surface 246A, and a first groove 242A is formed between another adjacent second support surface 246A. The angle between the first support surface 245A and the horizontal plane is smaller than the angle between the second support surface 246A and the horizontal plane. The bottom of the track ring 252A of the top cover ring 25A has a plurality of inclined first abutment surfaces 2523A and a plurality of inclined second abutment surfaces 2524A. Each of the opposite ends of any one of the first abutment surfaces 2523A is connected to a second abutment surface 2524A. Each of the opposite ends of any one of the second abutment surfaces 2524A is connected to a first abutment surface 2523A. A second protrusion 2521A is formed between one of the first abutment surfaces 2523A and an adjacent second abutment surface 2524A, and a second groove 2522A is formed between the first abutment surface 2523A and the horizontal plane. The included angle between the first abutment surface 2523A and the horizontal plane is smaller than the included angle between the second abutment surface 2524A and the horizontal plane. The projection of the second abutment surface 2524A of the track ring 252A of the top cap ring 25A onto the horizontal plane is included within the projection of the first support surface 245A of the base ring 24A onto the horizontal plane. In this way, one of the second protrusions 2521A and the adjacent second groove 2522A of the track ring 252A correspond to different positions of the first groove 242A of the base ring 24A. Therefore, when the cap assembly 30A is pressed and released, the bottle body 51A can only rotate in one direction, ensuring that the user can dispense a measured amount of the ointment 100A. That is, one of the second protrusions 2521A and the adjacent second groove 2522A of the track ring 252A of the top cap ring 25A are located above the first support surface 245A of the base ring 24A, so that when the user presses and releases the cap assembly 30A, the bottle body 51A can only rotate in one direction, ensuring that the user can dispense a measured amount of the ointment 100A.

[0126] Further, see attached document. Figures 13 to 15The press-type cream jar includes a shoulder sleeve 60A, which is fitted onto the outside of the cap 35A and fixedly installed on the bottom shell 10A. The shoulder sleeve 60A reduces the gap between the bottom shell 10A and the cap 35A, thus improving the aesthetics of the press-type cream jar. Preferably, the shoulder sleeve 60A has at least one second retaining rib 61A, and the bottom shell wall 15A of the bottom shell 10A has at least one second retaining groove 151A. The second retaining rib 61A of the shoulder sleeve 60A is engaged with the second retaining groove 151A of the bottom shell wall 15A of the bottom shell 10A to securely install the shoulder sleeve 60A onto the bottom shell 10A. Preferably, the shoulder sleeve 60A has an abutment ring 62A, which is fitted onto the top edge of the bottom shell wall 15A1 of the bottom shell 10A.

[0127] Continue to refer to the appendix Figures 13 to 15 The press-type cream jar further includes a cover 70A, which is detachably mounted on the shoulder sleeve 60A. When the cover 70A is mounted on the shoulder sleeve 60A, the cover 70A covers the cap 35A. After the cover 70A is removed from the shoulder sleeve 60A, the cap 35A is exposed. Preferably, the shoulder sleeve 60A has at least one third retaining rib 63A, and the cover 70A has at least one third retaining groove 71A. When the cover 70A is mounted on the shoulder sleeve 60A, the third retaining rib 63A of the shoulder sleeve 60A is engaged with the third retaining groove 71A of the cover 70A, preventing the cover 70A from automatically detaching from the shoulder sleeve 60A.

[0128] Appendix Figures 19 to 23The use of the press-type cream jar is illustrated. Specifically, when the cap assembly 30A is not pressed, the protrusion 5121A of the driven post 512A of the bottle body 51A is held in the second groove 2522A of the cap ring body 251A of the top cap ring 25A. When the user presses the cap assembly 30A, the cap assembly 30A and the bottle assembly 50A move downwards synchronously. During this process, on the one hand, the reset element 40A is compressed and deformed to accumulate elastic potential energy; on the other hand, the column protrusion 5121A of the driven column 512A slides along the first support surface 245A of the base ring 24A toward the first groove 242A of the base ring 24A. The bottle 51A and the piston 52A rotate counterclockwise relative to the cap assembly 30A. At the same time, as the thread 542A of the drive sleeve 54A slides in the thread groove 531A of the threaded column 53A, the threaded column 53A moves upward and pushes the piston 52A to move upwards synchronously. Thus, the ointment 100A supported by the piston 52A is scooped up by the spatula 34A and taken out through the top ointment outlet 32A of the cap assembly 30A. When the user releases the cap assembly 30A, the reset element 40A pushes the cap assembly 30A and the bottle assembly 50A upward synchronously during the process of restoring the initial state. During this process, the protrusion 5121A of the driven post 512A slides along the first abutting surface 2523A of the track ring 252A of the top cover ring 25A towards the second groove 2522A of the track ring 252A. The bottle 51A and the piston 52A rotate counterclockwise relative to the cap assembly 30A. At the same time, as the thread 542A of the drive sleeve 54A slides in the thread groove 531A of the threaded post 53A, the threaded post 53A moves upward and pushes the piston 52A upward synchronously. Thus, the ointment 100A supported by the piston 52A is scooped up by the spatula 34A and taken out through the top ointment outlet 32A of the cap assembly 30A. It is understood that the specific arrangement of the base ring 24A and the top cap ring 25A ensures that each time the user presses and releases the cap assembly 30A, the bottle body 51A and the piston 52A will only rotate in a counterclockwise direction. Therefore, the amount of cream 100A discharged each time the user presses and releases the cap assembly 30A is fixed, thereby achieving quantitative dispensing of the cream 100A.
