Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging, and more specifically, to a packaging bottle. Background Technology

[0002] Some existing cosmetic packaging bottles already have the function of reusing the inner bottle after replacement, which saves costs and is also more environmentally friendly. There are many ways to replace the inner bottle, such as taking it out from the top or the bottom, but overall they are not reliable or convenient enough. Some may be accidentally touched or misoperated, causing the inner bottle to fall out. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a packaging bottle that can be replaced by pressing the pressing block upward against the rotating ring and rotating it to remove it from the bottom of the replacement part. A certain amount of force is required to rotate the ring more than 30 degrees. The operation is convenient and reliable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A packaging bottle includes an outer bottle, a base, a pressing block, a positioning block, a replacement part, a fastening device, and a rotating ring. The replacement part is housed inside the outer bottle. The lower inner wall of the outer bottle has an outer bottle groove. The fastening device is slidably disposed above the positioning block. The fastening device includes a fastening seat protrusion that matches the outer bottle groove. The fastening seat protrusion is fastened to the outer bottle groove to keep the replacement part above the positioning block. The base is connected to the positioning block. The pressing block is connected to the base and is axially movable. The pressing block includes a push post located at the top. The rotating ring is vertically opposite to the push post. When the pressing block moves toward the rotating ring, the push post abuts against the rotating ring and drives the rotating ring to rotate, causing the fastening seat protrusion to disengage from the outer bottle groove. When the fastening seat protrusion is disengaged from the outer bottle groove, the base, pressing block, positioning block, replacement part, fastening device, and rotating ring can detach from the bottom of the outer bottle.

[0006] As a further configuration, the positioning block includes a support, and the fastening device includes a fastening seat, a plug, and a second spring. The fastening seat protrusion is located on the outer side wall of the fastening seat. The fastening seat includes an insert ring and a fastening seat shaft located on its inner side. The rotating ring is fitted with the fastening seat shaft with a clearance fit. The plug is fixedly installed on the inner end of the fastening seat shaft. The second spring is sleeved around the outer side of the fastening seat shaft. The two ends of the second spring respectively abut against the rotating ring and the plug. The end of the rotating ring near the second spring abuts against the end face of the support. The insert ring includes a first recessed area and a second recessed area distributed circumferentially. The first recessed area includes a first trough, and the second recessed area includes a second trough. The depth of the first trough is greater than the depth of the second trough. The rotating ring includes a tooth that matches the insert ring. When the tooth abuts against the second trough, the fastening seat protrusion is fastened to the outer bottle groove. When the tooth abuts against the first trough, the fastening seat protrusion is disengaged from the outer bottle groove.

[0007] As a further configuration, when the insert tooth abuts at the junction of the first and second recessed areas, the distance between the outer end face of the buckle protrusion and the outer bottle groove is closest, and the distance between the end face of the plug near the second spring and the support is closest. When the insert tooth moves in the second recessed area, the distance between the outer end face of the buckle protrusion and the outer bottle groove gradually decreases. When the insert tooth moves in the first recessed area, the distance between the outer end face of the buckle protrusion and the outer bottle groove gradually increases. When the insert tooth abuts at the first trough, the distance between the outer end face of the buckle protrusion and the outer bottle groove reaches its maximum.

[0008] As a further feature, the rotating ring includes circumferentially distributed rotating teeth, the push post and the rotating teeth at least partially overlap in the vertical plane, the base includes a limiting plate, the pressing block includes a pressing edge, the push post moves upward until the pressing edge abuts against the limiting plate, and the push post abuts the rotating teeth. During the movement, the insert teeth gradually enter the first recessed area from the location of the second trough (81521) or gradually enter the second recessed area from the location of the first trough.

[0009] As a further feature, a first spring is also included. The base includes a top base plate, a peripheral base sidewall, and a spring seat. The upper and lower ends of the first spring abut against the bottom surfaces of the spring seat and the pressing block, respectively. The top base plate has a notch and a downwardly extending buckle. The buckle includes an outwardly extending buckle portion. The push post is located between the base sidewall and the buckle. The pressing block includes a side strip protrusion extending inward. The side strip protrusion abuts against the upper end of the buckle portion. The push post can move through the top plate notch toward the rotating ring.

[0010] As a further feature, the system also includes a guide post and a top plate. The guide post is rotatably connected to the positioning block and is concentrically arranged with the positioning block. The lower end of the top plate is rotatably connected to the upper end of the guide post and is concentrically arranged with the top plate. The base is rotatably connected to the positioning block and can rotate the guide post by rotating the base around the positioning block. The top plate includes a side protrusion. The replacement part includes an inner bottle. The outer wall of the inner bottle is provided in an inner bottle groove that is adapted to the side protrusion. The side protrusion is fastened to the inner bottle groove.

[0011] As a further configuration, there are three of each of the first and second recessed areas, arranged alternately in a circumferential direction. Each first and second recessed area occupies 60 degrees of a circumference. The first trough of each first recessed area occupies 30 degrees of a circumference on both sides, and the second trough of each second recessed area occupies 30 degrees of a circumference on both sides. The pusher pushes the rotating teeth against the moving process so that the rotation angle of the insert teeth is greater than 30 degrees and less than 60 degrees.

[0012] As a further feature, the positioning block includes an extension channel, and the fastening device includes a guide post that is slidably disposed in the extension channel.

[0013] As a further feature, the positioning block includes a disc body through hole, the disc body through hole and the push post are vertically opposite each other, the projection of the rotating ring on the positioning block is located in the area where the disc body through hole is located, and the rotating ring and the push post are located above and below the disc body through hole, respectively.

[0014] As a further configuration, the buckle shaft includes a first buckle shaft and a second buckle shaft, the outer diameter of the first buckle shaft is larger than the outer diameter of the second buckle shaft, the swivel ring is fitted with the first buckle shaft with clearance, and the plug is fixedly installed at the end of the second buckle shaft.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By pressing the pressing block upwards to push the rotating ring to rotate, the insert tooth rotates from the second trough into the wall of the first recessed area and then retracts the pressing block. This operation can be judged by pressing the edge against the limiting plate. At this time, the pressing block can no longer rise. After the pressing block retracts, the insert tooth automatically slides until the insert tooth abuts against the first trough. Only then is the process of disengaging the buckle protrusion from the outer bottle groove realized, and the replacement part can be removed for use.

[0017] Second, pressing the pressing block requires overcoming the force of the first spring, and during the rotation of the ring, it requires overcoming the force of the second spring. This ensures that there will be no malfunctions and that the operation is convenient and reliable. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 1-22 As shown, this embodiment discloses a packaging bottle, including an outer bottle 1, a base 2, a pressing block 3, a positioning block 4, a guide post 5, a top plate 6, a replacement part 7, a fastening device 8, a rotating ring 9, and a first spring 35. (Refer to...) Figure 2 The replacement part 7 is housed inside the outer bottle 1. Under normal conditions (when not in use), the upper and lower ends of the replacement part 7 do not extend beyond the upper and lower ends of the outer bottle 1.

[0043] Reference Figure 4 The replacement part 7 includes an inner bottle 71, an inner bottle bottom plate 72 located at the bottom, a piston 73, a pump 74, a shoulder sleeve 75, and a nozzle 76. The piston 73 is located inside the inner bottle 71 and its outer edge is press-fitted with the inner wall of the inner bottle 71. The inner bottle bottom plate 72 is fastened to the bottom of the inner bottle 71. The pump 74 is installed at the upper end of the inner bottle 71 and is pressed by the shoulder sleeve 75. The shoulder sleeve 75 is threaded to the upper end of the inner bottle 71. The nozzle 76 is inserted into the upper end of the pump 74. These are all existing technologies.

[0044] Reference Figure 17 The inner bottle 71 includes an elliptical inner bottle end face 713 and a neck 712 located at the upper end of the inner bottle end face 713. The upper outer wall of the neck 712 is provided with an external thread 7121, and the lower outer wall of the neck 712 extends outward to form two symmetrical positioning blocks 711. The lower outer wall of the inner bottle 71 is provided with an inner bottle groove 714, and the inner bottle groove 714 is also provided with a groove protrusion 7141.

[0045] Reference Figure 4 , Figure 18 , Figure 19The shoulder sleeve 75 includes a first shoulder sleeve ring 751, a second shoulder sleeve ring 752, and a third shoulder sleeve ring 753, which are spaced apart from the inside to the outside. The first shoulder sleeve ring 751 and the second shoulder sleeve ring 752 are both circular rings, and the third shoulder sleeve ring 753 is an elliptical ring. A circular receiving groove 755 is formed between the first shoulder sleeve ring 751 and the second shoulder sleeve ring 752. Two annular channels 7511 are formed at the upper end of the first shoulder sleeve ring 751. A first protrusion 7512 and a second protrusion 7513 are formed at each annular channel 7511. The width of the annular channel 7511 at the location of the first protrusion 7512 and the second protrusion 7513 is smaller than the width of the annular channels 7511 in other parts. The first shoulder sleeve ring 751 is also provided with a vertical straight channel 7514. The upper end of the straight channel 7514 is connected to one end of the annular channel 7511. The entire straight channel 7514 is connected to the receiving groove 755. Two straight channels 7514, one large and one small, are designed for easy identification and positioning during assembly. The inner wall of the second shoulder collar 752 has an internal thread 7521 that matches the external thread 7121. The outer wall of the second shoulder collar 752 has outwardly protruding positioning pieces 754. There are two sets of positioning pieces 754, each set consisting of two spaced-apart positioning pieces 754. The lower ends of the two positioning pieces 754 in each set have a height difference. This height difference refers to the different distances between the lower ends of the two positioning pieces 754 in the same set and the end face 713 of the inner bottle. Specifically, along the direction in which the shoulder collar 75 is screwed into the inner bottle 71, the positioning piece 754 with the higher lower end passes over the positioning block 711 first, while the positioning piece 754 with the lower lower end is restricted by the positioning block 711 and cannot pass over it. That is, when the shoulder collar 75 is assembled in place, the positioning block 711 is located between the two positioning pieces 754 in the same set.

[0046] Reference Figure 20The nozzle 76 includes a downwardly extending nozzle ring 761. The inner wall of the nozzle ring 761 has two nozzle protrusions 762, one large and one small, corresponding one-to-one with the two straight channels 7514. Specifically, one nozzle protrusion 762 consists of two protrusions, making it wider overall, while the other is a single protrusion. The nozzle ring 761 and the receiving groove 755 are vertically aligned. In normal operation, when not in use, the nozzle protrusions 762 are located in the annular channel 7511, specifically at one end of the annular channel 7511 where the first protrusion 7512 is located. Thus, the nozzle protrusions 762 are constrained by the first protrusion 7512, and are positioned without external force. When in use, the nozzle protrusion 762 will not pass the first protrusion 7512, and the nozzle 76 is locked and cannot be pressed down. When it is necessary to press the nozzle 76 to use it, rotate the nozzle 76 so that the nozzle protrusion 762 passes the first protrusion 7512 and then the second protrusion 7513 and comes to the top of the straight channel 7514. At this time, press the nozzle 76, and the nozzle protrusion 762 can be inserted into the straight channel 7514, so that the packaging bottle can be used normally. The second protrusion 7513 plays a positioning role. During the rotation of the nozzle 76, the rotation stops after passing the second protrusion 7513, so that the nozzle protrusion 762 can be aligned with the straight channel 7514 below.

[0047] Reference Figure 6 The lower inner wall of the outer bottle 1 is provided with an outer bottle groove 12, and the lower inner wall of the outer bottle 1 is also provided with an avoidance notch 11 and an outer bottle step 13. There are two of each of the avoidance notch 11, outer bottle groove 12, and outer bottle step 13, and they are symmetrically distributed.

There are three first recessed areas 8151 and three second recessed areas 8152, which are arranged alternately in a circumferential direction. The first recessed area 8151 includes a first trough 81511, and the second recessed area 8152 includes a second trough 81521. The depth of the first trough 81511 is greater than the depth of the second trough 81521. The angle from a first trough 81511 to an adjacent second trough 81521 is 60 degrees. Each first depression region 8151 and each second depression region 8152 occupies 60 degrees of a circumference. The first trough 81511 of each first depression region 8151 occupies 30 degrees of a circumference on both sides, that is, the first trough 81511 is located at the center of the first depression region 8151. The second trough 81521 of each second depression region 8152 occupies 30 degrees of a circumference on both sides, that is, the second trough 81521 is located at the center of the second depression region 8152.

[0054] Reference Figure 15 The plug 82 includes a plug disc 821 and a plug post 822. The inner wall of the plug post 822 is provided with a plug post groove 8221. The plug post 822 is inserted into the second buckle shaft 814 to achieve the connection between the two. The plug post groove 8221 is adapted to the shaft protrusion 8141. The second spring 83 is sleeved around the buckle shaft 816. The outer diameter of the plug post 822 is basically equal to the outer diameter of the first buckle shaft 813, so that the second spring 83 will have a better performance.

[0055] Reference Figure 16The rotating ring 9 has a rotating ring hole 93 at its center. The rotating ring 9 includes circumferentially distributed rotating teeth 91 and insert teeth 92 that mate with insert rings 815. The center lines of the multiple rotating teeth 91, the center lines of the multiple insert rings 815, and the buckle shaft 816 are coaxial. The rotating ring 9 is vertically opposite to the push post 33. The push post 33 and the rotating teeth 91 at least partially overlap in the vertical plane. Thus, when the push post 33 moves upward, it will inevitably hit the rotating teeth 91 and drive the entire rotating ring 9 to rotate. The projection of the rotating teeth 91 on the positioning block 4 is located in the area where the disc body through hole 411 is located.

[0056] Reference Figure 21 The rotating ring 9 is fitted with the first buckle shaft 813 with a clearance fit. The two ends of the second spring 83 abut against the end faces of the rotating ring 9 and the plug 821, respectively. The end of the rotating ring 9 near the second spring 83 abuts against the end face of the support 47.

[0057] Reference Figure 21 The pressing block 3 moves toward the rotating ring 9, causing the pusher 33 to abut against the rotating tooth 91 and rotate the rotating ring 9 so that the buckle protrusion 8111 disengages from the outer bottle groove 12. Specifically, in the initial state, refer to... Figure 21 In the first diagram, the insert 92 abuts against the second trough 81521, and the buckle protrusion 8111 is connected to the outer bottle groove 12. During the replacement operation, the pressing block 3 is pressed upwards, the rotating ring 9 rotates, the insert 92 moves away from the second trough 81521 and moves along the wall of the second recessed area 8152, at which time the fastening device 8 is pushed outwards (outwards i.e., the outer side). Figure 21 When the insertion tooth 92 reaches the junction of the first recessed area 8151 and the second recessed area 8152, the outer end face of the buckle protrusion 8111 is closest to the outer bottle groove 12, the end face of the plug 82 near the second spring 83 is closest to the support 47, and the buckle protrusion 8111 is most tightly engaged with the outer bottle groove 12 (the buckle protrusion 8111 is located on the far left). Figure 21 In the second diagram, the rotating ring 9 continues to rotate, the insert tooth 92 enters the wall of the first recessed area 8151, and the fastening device 8 gradually moves to the right. At this time, the push post 33 has moved upward to the pressing edge 36 and abuts against the limiting plate 27, and the push post 33 can no longer move upward (see reference). Figure 22 The process of the pusher 33 pressing against and moving the rotating tooth 91 causes the insertion tooth 92 to rotate at an angle greater than 30 degrees and less than 60 degrees. An angle exceeding 30 degrees allows the insertion tooth 92 to enter the wall of the first recessed area 8151 from the second trough 81521. Then, the pusher 33 moves downwards to reset, and the insertion tooth 92, already inside the wall of the first recessed area 8151, automatically slides until it abuts against the first trough 81511. At this point, the buckle protrusion 8111 disengages from the outer bottle groove 12. Figure 21 The state of the third image. The entire process involves rotating ring 9 by 60 degrees.

[0058] When the insert tooth 92 moves in the second recessed area 8152, the distance between the outer end face of the buckle protrusion 8111 and the outer bottle groove 12 gradually decreases. When the insert tooth 92 moves in the first recessed area 8151, the distance between the outer end face of the buckle protrusion 8111 and the outer bottle groove 12 gradually increases. When the insert tooth 92 reaches the first trough 81511, the distance between the outer end face of the buckle protrusion 8111 and the outer bottle groove 12 reaches its maximum.

[0059] With the buckle protrusion 8111 detached from the outer bottle groove 12, the base 2, pressing block 3, positioning block 4, guide post 5, top plate 6, replacement part 7, fastening device 8, and rotating ring 9 can be detached from the bottom of the outer bottle 1. After replacing the replacement part 7, it can be reinstalled for reuse. Only the replacement part 7 needs to be replaced each time. The installation process is also done by pressing the pressing block 3, which is the opposite of the disassembly process. At this time, the push post 33 presses the rotating tooth 91 against the moving tooth 92, which gradually enters the second recessed area 8152 from the first trough 81511. After the push post 33 moves down, the tooth 92 automatically slides from the second recessed area 8152 until the tooth 92 abuts the second trough 81521. At this time, the buckle protrusion 8111 and the outer bottle groove 12 are fastened and connected.
