Description

Technical Field

[0001] This utility model relates to a container for holding pastes, and more particularly to a paste bottle. Background Technology

[0002] Cream-based cosmetics, such as body balms, are a common type of cosmetic and are packaged in cream bottles. For example, in Chinese utility model patent CN208064735U, the inventor disclosed a paste bottle, which includes a bottle body and a threaded shaft screwed to the bottle body. The bottle body has a receiving hole for receiving paste from the outside. One end of the threaded shaft protrudes into the receiving hole. The paste bottle also includes an end cap, a sleeve, and a top cap. The end cap is detachably connected to the other end of the threaded shaft and is used to seal one end of the receiving hole. The top cap is detachably connected to the upper end of the bottle body. The sleeve is fixedly embedded inside the top cap and is used to seal the other end of the receiving hole. The bottle body has a main body and a reduced diameter part connected to the main body. The reduced diameter part is located inside the main body and its outer diameter is smaller than that of the main body. The end cap has a blind hole, and the reduced diameter part is received in the blind hole. The other end of the threaded shaft is connected to a fixed plate. The end cap and the fixed plate are detachably connected. A sealing ring is sleeved on the outside of the fixed plate to abut against the inner wall of the reduced diameter part. The sealing ring is used to seal the gap between the fixed plate and the reduced diameter part. The fixed plate is equipped with a stop block and a slot. The stop block abuts against the end face of the free end of the reduced diameter section, and the end cap is equipped with a retaining rib for protruding into the slot. The receiving hole of the main body contains a support plate for abutting against the reduced diameter section, and the threaded shaft is screwed to the support plate. The support plate has a guide groove, and the main body has a guide strip protruding into the receiving hole, which is housed within the guide groove. A deficiency in existing ointment bottles is the unreasonable design of the connection structure between the bottom of the threaded shaft and the fixed plate. Because the bottom of the threaded shaft is relatively thin, and the connection point between the bottom of the threaded shaft and the fixed plate is a stress concentration area, during the rotation of the threaded shaft driven by the fixed plate, when the support plate descends to its lowest position while the fixed plate is still rotating, the support plate will apply a circumferential reaction force to the threaded shaft. This causes stress to continuously concentrate at the connection point between the bottom of the threaded shaft and the fixed plate, leading to deformation or even breakage of the bottom of the threaded shaft. This affects the product's lifespan and safety, resulting in a poor user experience and impacting the product's market competitiveness. Therefore, the inventors of this utility model aim to provide an ointment bottle with a more reliable structure. Utility Model Content

[0003] One objective of this invention is to provide a paste bottle in which a reinforcing post is arranged between the base and the threaded post of the rotor. The outer diameter of the reinforcing post is larger than that of the threaded post. When the rotor is rotated by the end cap, the reaction force applied to the rotor in the circumferential direction by the support plate is less likely to cause the rotor to break. Therefore, compared with the prior art, the paste bottle of this invention has a more reliable structure.

[0004] One objective of this utility model is to provide a paste bottle, wherein the rotor is provided with a first anti-rotation part on the reinforcing column and the support tray is provided with a second anti-rotation part. During the process of the rotor driving the support tray to move downward by rotating the end cap in the opposite direction, after the support tray moves downward to the lowest position, the first anti-rotation part and the second anti-rotation part cooperate with each other to prevent the end cap from continuing to rotate, avoid the support tray from slipping and spinning freely, thereby ensuring the rotation feel of the end cap.

[0005] One objective of this invention is to provide a paste bottle, wherein the first stop surface of the first anti-rotation part extends vertically upward from the end face of the top of the reinforcing column, and the second stop surface of the second anti-rotation part extends vertically downward from the end face of the bottom of the support tray. During the process of the rotor driving the support tray to move downward by rotating the end cap in the opposite direction, after the support tray moves downward to the lowest position, the first stop surface of the first anti-rotation part and the second stop surface of the second anti-rotation part fit together, preventing the second anti-rotation part from crossing the first anti-rotation part, thereby reducing the circumferential force on the rotor and ensuring the reliability of the paste bottle.

[0006] One objective of this invention is to provide a paste bottle, wherein a first anti-rotation part connects the threaded post and the reinforcing post, so as to reinforce the connection between the threaded post and the reinforcing post by the first anti-rotation part, thereby improving the reliability of the paste bottle.

[0026] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0027] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0028] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0029] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 9 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the ointment bottle includes a bottle body 10, a rotor 20, a support tray 30, an end cap 40 and a top cap 50.

[0030] Specifically, the bottle body 10 has a cavity 11, which has a top opening 111 and a bottom opening 112. Preferably, the bottle body 10 is cylindrical. Optionally, in other examples of this utility model, the bottle body 10 is rectangular.

[0031] The rotor 20 includes a base 21, a reinforcing post 22, and a threaded post 23. The reinforcing post 22 extends upward from the base 21, and the threaded post 23 extends upward from the reinforcing post 22; that is, the reinforcing post 22 connects the base 21 and the threaded post 23. The outer diameter of the reinforcing post 22 is larger than that of the threaded post 23, making the reinforcing post 22 more robust and less prone to breakage. In this invention, the base 21, reinforcing post 22, and threaded post 23 of the rotor 20 are integrally formed, and the plastic material can be used to form the base 21, reinforcing post 22, and threaded post 23 as a single unit.

[0032] The base 21 of the rotor 20 is rotatably mounted at the bottom cavity 112 of the bottle cavity 11 of the bottle body 10. The reinforcing post 22 and the threaded post 23 are located in the bottle cavity 11 of the bottle body 10, wherein the reinforcing post 22 and the threaded post 23 rotate as the base 21 rotates.

[0033] The support tray 30 has a threaded hole 31 through which the threaded post 23 of the rotor 20 passes. That is, the support tray 30 is screwed onto the threaded post 23 of the rotor 20. The support tray 30 is configured to move up and down within the bottle cavity 11 along the height direction of the bottle body 10 when the rotor 20 rotates. In other words, the rotor 20 can drive the support tray 30, and the direction of movement of the support tray 30 is restricted to the height direction, preventing rotation relative to the bottle body 10 in the circumferential direction. The support tray 30 is used to support the paste 100.

[0034] In order to ensure that the support tray 30 can only move up and down along the height direction when the rotor 20 rotates, in this invention, the peripheral wall of the support tray 30 is provided with at least one guide groove 32, and the inner wall of the bottle body 10 has at least one guide strip 12 arranged along the height direction. The guide strip 12 of the bottle body 10 protrudes into the guide groove 32 of the support tray 30. Thus, when the rotor 20 rotates, the guide groove 32 of the support tray 30 and the guide strip 12 of the bottle body 10 cooperate with each other, so that when the rotor 20 rotates, it drives the support tray 30 to move up and down within the bottle cavity 11 along the height direction of the bottle body 10. (See attached...) Figures 1 to 9In this specific example of the ointment bottle of the present invention, the number of guide grooves 32 of the support tray 30 is multiple, for example, three, and the three guide grooves 32 are evenly arranged. Correspondingly, the number of guide strips 12 of the bottle body 10 is multiple, for example, three, and the three guide strips 12 are evenly arranged. Each guide strip 12 of the bottle body 10 protrudes into each guide groove 32 of the support tray 30. In this way, when the rotor 20 is rotated, multiple positions of the support tray 30 can be limited by the guide strips 12 at different positions of the bottle body 10, avoiding the problem of uneven force on the support tray 30 in the circumferential direction.

[0035] Optionally, in other examples of the ointment bottle of this utility model, the guide groove 32 may be provided on the inner wall of the bottle body 10, and correspondingly, the guide strip 12 is provided on the peripheral wall of the support tray 30. The guide strip 12 of the support tray 30 protrudes into the guide groove 32 of the bottle body 10, so that when the rotor 20 rotates, the guide strip 12 of the support tray 30 and the guide groove 32 of the bottle body 10 cooperate with each other, so that when the rotor 20 rotates, it drives the support tray 30 to move up and down in the bottle cavity 11 only along the height direction of the bottle body 10.

[0036] The end cap 40 is rotatably mounted on the bottom of the bottle body 10, and the base 21 of the rotor 20 is fixedly mounted on the end cap 40. When the user rotates the end cap 40, the end cap 40 drives the rotor 20 to rotate relative to the bottle body 10, thereby driving the support tray 30 to move up and down in the bottle cavity 11 along the height direction of the bottle body 10.

[0037] The top cover 50 is detachably mounted on the top of the bottle body 10. When the top cover 50 is mounted on the top of the bottle body 10, the top cover 50 closes the top opening 111 of the bottle cavity 11 of the bottle body 10. After the top cover 50 is removed from the top of the bottle body 10, the top cover 50 opens the top opening 111 of the bottle cavity 11 of the bottle body 10.

[0038] Specifically, after the user removes the top cap 50 from the top of the bottle body 10 to open the top cavity 111 of the bottle cavity 11 of the bottle body 10, the user can hold the bottle body 10 with one hand and rotate the end cap 40 in one direction with the other hand. The end cap 40 drives the rotor 20 to rotate, which is equivalent to the bottle body 10. The guide strip 12 of the bottle body 10 and the guide groove 32 of the support tray 30 cooperate with each other, so that the rotor 20 drives the support tray 30 to move upward, thereby exposing the top of the ointment 100 to the top cavity 111 of the bottle cavity 11 of the bottle body 10 for the user to use the ointment 100. After use, rotate the end cap 40 in the opposite direction. The rotor 20 drives the tray 30 to move downward, causing the top of the ointment 100 to retract into the top opening 111 of the bottle cavity 11 of the bottle body 10. Then, the top cap 50 is installed on the top of the bottle body 10 to close the top opening 111 of the bottle cavity 11 of the bottle body 10. During the process of the rotor 20 driving the tray 30 downward by rotating the end cap 40 in the opposite direction, after the tray 30 moves to the lowest position, if the end cap 40 continues to rotate, since the rotor 20 has a tendency to rotate relative to the tray 30 in the circumferential direction, the tray 30 will apply a circumferential reaction force to the rotor 20. In this utility model, since the rotor 20 is provided with a reinforcing post 22 that is thicker than the threaded post 23 between the base 21 and the threaded shaft 23, the rotor 20 is less likely to break after the tray 30 applies a circumferential reaction force to the rotor 20. Compared with the prior art, the ointment bottle of this utility model has a more reliable structure.

[0039] The ointment bottle of this utility model adopts a bottom-filling method to fill the ointment 100. Specifically, the base 21 of the rotor 20 has at least one filling channel 211, and the tray 30 has at least one disc channel 33. Before filling, the tray 30 is in the lowest position (i.e., the distance between the tray 30 and the base 21 is the smallest). The filling channel 211 of the base 21 and the disc channel 33 of the tray 30 are directly opposite each other, and the opening of the filling channel 211 of the base 21 faces upward. The fluid paste 100 is allowed to be poured into the bottle cavity 11 of the bottle 10 through the filling channel 211 of the base 21 and the disc channel 33 of the tray 30. After solidification, the paste 100 and the tray 30 are combined into a whole, so that the paste 100 rises and falls with the rise and fall of the tray 30. After filling, the end cap 40 is installed on the bottle 10 and the base 21 of the rotor 20.

[0040] During the filling process, because the paste bottle is inverted, the top cap 50 is located at the bottom. To prevent the fluid paste 100 from leaking through the top opening 111 of the bottle cavity 11 of the bottle body 10, in this invention, the paste bottle further includes a sealing cap 60. The sealing cap 60 has an insertion ring 61 and an overlapping ring 62 on its edge. The outer diameter of the insertion ring 61 is the same as the inner diameter of the top opening 111 of the bottle cavity 11 of the bottle body 10, and the outer diameter of the overlapping ring 62 is the same as the outer diameter of the top opening 111 of the bottle cavity 11 of the bottle body 10. The sealing cap 60 is inserted into the top opening 111 of the bottle body 10 by the insertion ring 61. The top opening 111 of the bottle cavity 11 and the overlapping ring 62 are mounted on the top of the bottle body 10 such that they abut against the top edge of the bottle cavity 11 of the bottle body 10 to seal the top opening 111 of the bottle cavity 11. After the top cap 50 is screwed onto the top of the bottle body 10, the top cap 50 presses against the overlapping ring 62 of the sealing cap 60 to ensure that the sealing cap 60 seals the top opening 111 of the bottle cavity 11 of the bottle body 10. Thus, during filling, the sealing cap 60 is used to prevent the fluid paste 100 being filled into the bottle cavity 11 of the bottle body 10 from leaking from the top opening 111 of the bottle cavity 11 of the bottle body 10. In addition, the shape of the top of the cured paste 100 is related to the surface shape of the inner wall of the sealing cap 60. For example, in this invention, the surface shape of the inner wall of the sealing cap 60 is concave, and correspondingly, the shape of the top of the paste 100 is convex. Therefore, the shape of the top of the paste 100 can be adjusted by changing the surface shape of the inner wall of the sealing cap 60.

[0041] In this invention, the base 21 of the rotor 20 includes a ring body 212 and at least two connecting arms 213. The outer ends of each connecting arm 213 are respectively connected to the ring body 212, and the inner walls of each connecting arm 213 are respectively connected to the bottom of the reinforcing column 22. The base 21 forms the filling channel 211 between two adjacent connecting arms 213.

[0042] Furthermore, the seat ring 212 has an annular groove 2121 with a circumferential opening, and the inner wall of the bottle body 10 is provided with a protruding ring 13 near the bottom cavity 112 of the bottle cavity 11. The protruding ring 13 of the bottle body 10 protrudes into the annular groove 2121 of the seat ring 212 to rotatably mount the seat body 21 to the bottom cavity 112 of the bottle cavity 11 of the bottle body 10. The protruding ring 13 of the bottle body 10 and the annular groove 2121 of the seat ring 212 cooperate with each other to prevent the rotor 20 from falling off the bottle body 10.

[0043] In this invention, the outer peripheral wall of the seat ring 212 has a first annular boss 2122 and a second annular boss 2123. The first annular boss 2122 and the second annular boss 2123 are arranged at intervals, and the second annular boss 2123 is located below the first annular boss 2122 to form the annular groove 2121 between the first annular boss 2122 and the second annular boss 2123. The lower surface of the second annular boss 2123 has an inclined guide slope 21231. The seat ring 212 further has two or more notches 2124, which extend from the bottom of the seat ring 212 through the second annular boss 2123 to the middle of the annular groove 2121, so that the second annular boss 2123 can deform inward when compressed. When assembling the rotor 20 and the bottle body 10, firstly, the rotor 20 is placed in the bottle cavity 11 of the bottle body 10 through the top cavity 111. At this time, the guide slope 21231 of the second annular boss 2123 of the seat ring 212 contacts the convex ring 13 of the bottle body 10. Secondly, the rotor 20 is pressed down. As the rotor 20 moves downward, the convex ring 13 of the bottle body 10 compresses the second annular boss 2123. This causes the second annular protrusion 2123 to be squeezed and deformed inward. After the second annular protrusion 2123 passes through the protruding ring 13 of the bottle body 10, the second annular protrusion 2123 deforms outward, causing the protruding ring 13 of the bottle body 10 to be inserted into the annular groove 2121 of the seat ring body 212. This allows the seat body 21 of the rotor 20 to be rotatably mounted at the bottom cavity 112 of the bottle cavity 11 of the bottle body 10, preventing the rotor 20 from falling off the bottle body 10.

[0044] Furthermore, the seat ring 212 has an insertion groove 2125, and the end cap 40 has an insertion arm 41 and an outer ring arm 42. After filling, when the insertion arm 41 of the end cap 40 is inserted into the insertion groove 2125 of the seat ring 212 to install the end cap 40 and the seat 21, the outer ring arm 42 of the end cap 40 surrounds the bottom cavity opening 112 of the bottle cavity 11 of the bottle body 10, preventing the seat 21 from being exposed. Preferably, the outer wall of the outer ring arm 42 of the end cap 40 is flush with the outer wall of the bottle body 10, making the ointment bottle more aesthetically pleasing.

[0045] Further, see Appendix Figure 2 , Figure 3 , Figures 5 to 8The rotor 20 further includes at least one first anti-rotation portion 24, which is disposed on the reinforcing post 22. The support tray 30 includes a disc body 34 and at least one second anti-rotation portion 35. The threaded hole 31, the guide groove 32, and the disc body channel 33 of the support tray 30 are all formed in the disc body 34, and the second anti-rotation portion 35 is disposed in the disc body 34. It is worth noting that in embodiments where the guide groove 32 is not required in the support tray 30, the disc body 34 also does not need to have the guide groove 32. Similarly, in embodiments where the disc body channel 33 is not required in the support tray 30, the disc body 34 also does not need to have the disc body channel 33. During the process of rotating the end cover 40 in the opposite direction and driving the support tray 30 downward, after the support tray 30 has moved to the lowest position, if the end cover 40 continues to be rotated, the first anti-rotation part 24 blocks the second anti-rotation part 35 in the circumferential direction to avoid the rotor 20 slipping. In this way, when the user rotates the end cover 40, as long as he feels resistance with his hand, he can confirm that the support tray 30 has moved to the lowest position.

[0046] In the appendix Figures 1 to 8 In this specific example of the ointment bottle of the present invention, the first anti-rotation part 24 is disposed at the top of the reinforcing post 22, and the first anti-rotation part 24 is connected to the bottom of the threaded post 23. Thus, the first anti-rotation part 24 can strengthen the connection strength at the joint between the reinforcing post 22 and the threaded post 23. The second anti-rotation part 35 is disposed at the bottom of the disc body 34. In this way, on the one hand, the first anti-rotation part 24 can prevent the second anti-rotation part 35 from rotating in the circumferential direction; on the other hand, the arrangement of the first anti-rotation part 24 and the second anti-rotation part 35 does not occupy space in the circumferential direction, which is beneficial to the miniaturization of the ointment bottle.

[0047] Furthermore, the first anti-rotation portion 24 of the rotor 20 has a first stop surface 241 and a first guide surface 242. The first stop surface 241 extends vertically upward from the end face of the top of the reinforcing column 22, and the first guide surface 242 extends obliquely between the top of the first stop surface 241 and the end face of the top of the reinforcing column 22. The second anti-rotation portion 35 of the support tray 30 has a second stop surface 351 and a second guide surface 352. The second stop surface 351 extends vertically downward from the end face of the bottom of the disc body 34, and the second guide surface 352 extends obliquely between the bottom of the second stop surface 351 and the end face of the bottom of the disc body 34. During the process of the rotor 20 driving the support tray 30 downward by rotating the end cap 40 in the reverse direction, after the support tray 30 moves to its lowest position, the first stop surface 241 of the first anti-rotation part 24 of the rotor 20 and the second stop surface 351 of the second anti-rotation part 35 of the support tray 30 are in surface contact, and the first guide surface 242 of the first anti-rotation part 24 and the second guide surface 352 of the second anti-rotation part 35 are in surface contact. In this way, during the process of the rotor 20 driving the support tray 30 downward by rotating the end cap 40 in the reverse direction, the support tray 30 is in surface contact. After the tray 30 moves downward to its lowest position, the first stop surface 241 of the first anti-rotation part 24 of the rotor 20 and the second stop surface 351 of the second anti-rotation part 35 of the tray 30 cooperate to prevent the user from continuing to rotate the end cap 40, thus avoiding slippage of the rotor 20. When rotating the end cap 40 in the forward direction, the first guide surface 242 of the first anti-rotation part 24 of the rotor 20 and the second guide surface 352 of the second anti-rotation part 35 of the tray 30 cooperate to allow the tray 30 to move upward along the height direction of the bottle body 10. Preferably, the first guide surface 242 of the first anti-rotation part 24 of the rotor 20 extends spirally between the top of the first stop surface 241 and the end face of the top of the reinforcing column 22, and the second guide surface 352 of the second anti-rotation part 35 of the tray 30 extends spirally between the bottom of the second stop surface 351 and the end face of the bottom of the disc body 34.

[0048] In this invention, since the first stop surface 241 of the first anti-rotation part 24 extends vertically upward from the top end face of the reinforcing column 22, and the second stop surface 351 of the second anti-rotation part 35 extends vertically downward from the bottom end face of the disc body 34, when the rotor 20 rotates to the position where the first stop surface 241 of the first anti-rotation part 24 and the second stop surface 351 of the second anti-rotation part 35 are in contact and the first anti-rotation part 24 blocks the second anti-rotation part 35, even if the user uses a slightly larger force to rotate the end cap 40, the first anti-rotation part 24 will not cross the second anti-rotation part 35 and cause the rotor 20 to continue rotating relative to the support tray 30. In this way, the circumferential reaction force applied by the support tray 30 to the rotor 20 is controlled within a reasonable range, avoiding the problem of rotor 20 breaking, thereby improving the reliability of the ointment bottle.

[0049] Optionally, in other embodiments of this invention, during the process of the rotor 20 driving the support tray 30 downward by rotating the end cap 40 in the opposite direction, after the support tray 30 moves downward to its lowest position, the first stop surface 241 of the first anti-rotation part 24 of the rotor 20 and the second stop surface 351 of the second anti-rotation part 35 of the support tray 30 are in face-to-face contact, and the first guide surface 242 of the first anti-rotation part 24 and the second guide surface 352 of the second anti-rotation part 35 are in a face-to-face state. In other words, there may be a gap between the first guide surface 242 of the first anti-rotation part 24 and the second guide surface 352 of the second anti-rotation part 35, and the two are not in direct contact.

[0050] In this invention, the rotor 20 includes two first anti-rotation portions 24. A first groove 25 is formed between the first stop surface 241 of one first anti-rotation portion 24 and the first guide surface 242 of the other first anti-rotation portion 24, meaning the rotor 20 has two first grooves 25. The support tray 30 includes two second anti-rotation portions 35. A second groove 36 is formed between the second stop surface 351 of one second anti-rotation portion 35 and the second guide surface 352 of the other second anti-rotation portion 35, meaning the support tray 30 has two second grooves 36. As the rotor 20 rotates, when each of the second anti-rotation portions 35 of the support tray 30 enters each of the first grooves 25 of the rotor 20, each of the first anti-rotation portions 24 of the rotor 20 enters each of the second grooves 36 of the support tray 30. In this way, the two first anti-rotation portions 24 of the rotor 20 can reliably block the two second anti-rotation portions 35 of the support tray 30, thereby preventing the rotor 20 from rotating relative to the support tray 30.
