Technical Field

[0001] This invention relates to the field of cosmetic packaging, and more specifically, to a replaceable packaging bottle and a method for replacing it. 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. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a replaceable packaging bottle and its replacement method. The replacement bottle can be removed from the bottom and replaced by pressing the pressing block upward to open the positioning block. The operation is convenient and reliable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a replaceable packaging bottle, comprising an outer bottle, a base, a pressing block, a positioning block, and a replacement part, wherein the replacement part is housed inside the outer bottle, and the lower inner wall of the outer bottle is provided with an outer bottle groove, the positioning block includes a spring piece, the spring piece including a spring piece protrusion that matches the outer bottle groove, the spring piece protrusion being fastened to the outer bottle groove to keep the replacement part above the positioning block, the base being connected to the positioning block, the pressing block being connected to the base and being axially movable, the pressing block moving toward the location of the spring piece to abut the spring piece and disengage the spring piece protrusion from the outer bottle groove, and in the state where the spring piece protrusion is disengaged from the outer bottle groove, the base, pressing block, positioning block, and replacement part can be detached from the bottom of the outer bottle.

[0005] As a further feature, the base includes a top base plate and an outer base sidewall. The top base plate has symmetrically distributed top plate notches and a downwardly extending fastener. The fastener includes an outwardly extending fastening portion. The upper end of the pressing block is located between the base sidewall and the fastener. The pressing block includes a side strip protrusion extending inward. The side strip protrusion abuts against the upper end of the fastening portion. The pressing block can move through the top plate notch toward the location of the spring clip.

[0006] As a further feature, the base has an inwardly extending protruding buckle at its center, and the positioning block includes a buckle groove that matches the protruding buckle, with the protruding buckle and the buckle groove being fastened together.

[0007] As a further feature, a top plate is also included, through which the positioning block supports the replacement part, and the top plate abuts against the upper end of the positioning block.

[0008] As a further feature, a guide post is also included. The positioning block includes a guide channel penetrating its outer wall. The guide channel includes a first channel located at a lower position and a third channel located at a higher position. The guide post includes a guide head that can move along the guide channel. When the guide head is located in the first channel, the upper end of the guide post does not contact the top plate. When the guide head is located in the third channel, the upper end of the guide post abuts against the top plate and the top plate is disengaged from the positioning block.

[0009] As a further feature, the base is provided with a central hole, and the base includes at least a pair of clamping bodies, with a base channel formed between the pair of clamping bodies. The base channel communicates with the central hole, and the guide head passes through the guide channel and extends into the base channel.

[0010] As a further feature, a spring is also included. The pressing block includes a central convex post with a central convex post step. The guide post includes an inner convex ring. The upper and lower ends of the spring abut against the inner convex ring and the central convex post step, respectively.

[0011] As a further feature, when the guide head is located in the first channel, the spring protrusion is restricted by the top plate and cannot disengage from the outer bottle groove. When the guide head is located in the third channel, the pressing block moves toward the location of the spring to abut against the spring and cause the spring protrusion to disengage from the outer bottle groove.

[0012] As a further configuration, a top plate and guide pillars are also included. The base includes a top base plate and peripheral base sidewalls. The base sidewalls are elliptical. The top base plate has downwardly extending fasteners, each fastener including an outwardly extending fastening portion. A base protrusion extends downward from the center of the top base plate, defining a central hole in the base. The positioning block includes a positioning disc body and a columnar portion located below the positioning disc body. The columnar portion extends into the central hole in the base. A protruding fastening portion is provided on the inner edge of the top base plate. A fastening groove is provided on the outer wall of the columnar portion, and the protruding fastening portion is fastened to the fastening groove. An inner protrusion and an outer protrusion are provided on the upper surface of the positioning disc body. The inner protrusion is located inside the outer protrusion, and the upper end of the inner protrusion is lower than the upper end of the outer protrusion. The top plate includes a plate body, a top plate protrusion located below the plate body, and an insert block located above the plate body. The lower end face of the plate body abuts against the upper end of the outer protrusion. The outer edge of the top plate protrusion has an outwardly protruding protrusion ring. The replacement part includes an inner bottle bottom plate located at the bottom. The inner bottle bottom plate has a bottom plate hole that matches the insert block. The insert block passes through the bottom plate hole. The outer edge of the pressing block is elliptical. The pressing block is adapted to the base and is located inside the base. The pressing block includes a pressing block bottom and a side strip. The inner wall of the side strip has a side strip protrusion. The side strip protrusion abuts against the buckle. At the upper end of the outer bottle, the bottom end of the outer bottle is provided with an outer bottle step. The outer edge of the positioning disc body forms a disc flange that extends into the outer bottle step. The upper end of the positioning disc body is provided with a vertical plate located inside the disc flange. The vertical plate body is clearance-fitted with the inner wall of the outer bottle. The columnar part is provided with a guide channel. The guide channel includes a first channel located at a lower position, a third channel located at a higher position, and a second channel connecting the first channel and the third channel. The first channel is provided with a first channel protrusion, and the third channel is provided with a second channel protrusion. The guide post includes a column body and a guide post ring located at the top of the column body. The guide post ring is located above the inner protrusion, and the outer contour of the guide post ring extends beyond the outer edge of the inner protrusion. The outline of the column includes a protruding guide head on its outer wall, which extends into a guide channel. When the guide head is at the end of the first channel, it is constrained by a protrusion in the second channel. When the guide head is at the end of the third channel, it is constrained by a protrusion in the second channel. The rotation angle of the guide head from the end of the first channel to the end of the third channel is 180 degrees. The upper end of the column and the positioning disc together form a disc notch, which connects to the guide channel. The disc notch includes a notch protrusion extending inward. The inner wall of the column is provided with a guide post inner protrusion ring, which is located above the protrusion ring and has an inner diameter smaller than the outer diameter of the protrusion ring.

[0013] A method for replacing a replaceable packaging bottle includes the following steps:

[0014] a. Rotate the base 180 degrees. At this time, the pressing block rotates 180 degrees synchronously with the base. During the rotation, the guide head of the guide post moves from the first channel of the positioning block to the third channel. The guide post is lifted and pushes the replacement part upward against the top plate, so that the top plate moves away from the positioning block.

[0015] b. Push the pressing block upwards. The pressing block passes through the notch on the top plate of the base and abuts against the spring piece. The spring piece deforms inwards so that the spring piece protrudes and disengages from the groove in the outer bottle.

[0016] c. Disconnect the base, pressing block, and positioning block from the bottom of the outer bottle, and also disconnect the replacement part from the bottom of the outer bottle.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The replacement part can be removed from the bottom and replaced by pressing the pressing block upwards to open the positioning block. The operation is convenient and reliable.

[0019] Second, the top plate constrains the positioning block, ensuring that even if the pressing block is accidentally touched during packaging and transportation, the positioning block cannot be dislodged, thus preventing malfunctions. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figures 1-17 As shown, this embodiment discloses a replaceable 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, and a spring 8. (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.

[0040] 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 inner bottle bottom plate 72 is provided with a bottom plate hole 721. The piston 73 is located inside the inner bottle 71 and the outer edge of the piston 73 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.

[0041] Reference Figure 14 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.

[0042] Reference Figure 4 , Figure 15 , Figure 16The 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. The inner wall of the second shoulder collar 752 is provided with an internal thread 7521 that matches the external thread 7121. The outer wall of the second shoulder collar 752 is provided with an outwardly protruding positioning piece 754. There are two sets of positioning pieces 754, each set including two spaced positioning pieces 754. There is a height difference between the lower ends of the two positioning pieces 754 in each set. This height difference means that the distance between the lower ends of the two positioning pieces 754 in the same set and the end face 713 of the inner bottle is different. Specifically, along the direction of screwing the shoulder collar 75 into the inner bottle 71, the positioning piece 754 with the higher lower end first passes the positioning block 711, and then the positioning piece 754 with the lower lower end is restricted by the positioning block 711 and cannot pass. That is, the shoulder collar 75 is assembled in place and the positioning block 711 is located between the two positioning pieces 754 in the same set.

[0043] Reference Figure 17 The nozzle 76 includes a downwardly extending nozzle ring 761. The inner wall of the nozzle ring 761 has two symmetrically distributed nozzle protrusions 762. The nozzle ring 761 is vertically opposite to the receiving groove 755. 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 without external force, the nozzle protrusions 762 will not cross the first protrusion 7512. At this time, the nozzle 76... When the nozzle 76 is locked and cannot be pressed down, rotate the nozzle 76 so that the nozzle protrusion 762 passes over the first protrusion 7512 and then over the second protrusion 7513 and comes above 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.

[0044] Reference Figure 6The 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. The avoidance notch 11 and outer bottle groove 12 are directly opposite each other, located at the two ends of the major axis of the ellipse, while the outer bottle step 13 is located at the two ends of the minor axis of the ellipse. (Refer to...) Figure 2 , Figure 5 The upper end of the outer bottle 1 is provided with an outer bottle middle hole 14. When not in use, the nozzle 76 does not extend beyond the outer bottle middle hole 14. When normal use is required, the nozzle 76 extends out of the outer bottle middle hole 14.

[0045] Reference Figure 7 , Figure 8 The base 2 includes a top base plate 22 and peripheral base sidewalls 21. The base sidewalls 21 are elliptical. The top base plate 22 has symmetrically distributed top plate notches 221 located at both ends of the major axis of the ellipse. The top base plate 22 has two symmetrically arranged buckle pieces 25 extending downwards. Each buckle piece 25 includes a buckling portion 251 extending outwards. The center of the base 2 has a base central hole 222. The center of the top base plate 22 extends downwards to form a base protrusion 24, which defines the base central hole 222. The base 2 includes at least one pair of clamping bodies 23 connected to the ends of the base protrusion 24 and connected to the top base plate 22 and the base sidewalls 21. A vertical base channel 223 is formed between the pair of clamping bodies 23, which communicates with the base central hole 222. The inner edge of the top base plate 22 has a protruding buckling portion 224.

[0046] Reference Figure 9 The pressing block 3 includes a pressing block bottom 31, side strips 32 located on both sides of the pressing block bottom 31, and a central protrusion 33. The pressing block bottom 31 is elliptical. The pressing block 3 is adapted to the base 2 and is located inside the base 2. The side strips 32 are located at both ends of the major axis of the ellipse. The central protrusion 33 is located at the center of the upper end face of the pressing block bottom 31. The inner wall of the side strips 32 is provided with inwardly extending side strip protrusions 34. The side strip protrusions 34 include an inclined portion 341 and a stop portion 342, wherein the inclined portion 341 is located above the stop portion 342. The side strip protrusions 34 abut against the upper end of the buckle portion 251. The central protrusion 33 is provided with a central protrusion step 331. The upper end of the side strip 32 is located between the base side wall 21 and the buckle piece 25. The side strip 32 can move upward through the top plate notch 221, that is, the pressing block 3 can move axially.

[0047] Reference Figure 10 , Figure 11The positioning block 4 includes a positioning disc body 41 and a columnar part 42 located below the positioning disc body 41. The columnar part 42 extends into the central hole 222 of the base. The outer wall of the columnar part 42 is provided with a fastening groove 48. The protruding fastening part 224 is fastened to the fastening groove 48. The upper end face of the positioning disc body 41 is provided with an inner protrusion 47, an outer protrusion 46, and a spring piece 49. There are two of each of the inner protrusion 47, outer protrusion 46, and spring piece 49. The inner protrusion 47 is located inside the outer protrusion 46, and the upper end of the inner protrusion 47 is lower than the upper end of the outer protrusion 46. The outer edge of the positioning disc body 41 forms a disc flange 411 that extends into the outer bottle step 13. The disc flange 411 allows the positioning block 4 and the outer bottle 1 to be precisely positioned and installed. The upper end of the positioning disc body 41 is provided with a fastening groove 48 located below the central hole 222 of the base. The disc flange 411 has an inner plate 45, which is in clearance fit with the inner wall of the outer bottle 1. The columnar part 42 is provided with a guide channel 43 penetrating its outer wall. The guide channel 43 includes a first channel 431 located at a lower position, a third channel 433 located at a higher position, and a second channel 432 connecting the first channel 431 and the third channel 433. The first channel 431 and the third channel 433 are basically horizontally arranged, while the second channel 432 is obliquely arranged. The first channel 431 is provided with a first channel protrusion 4311, and the third channel 433 is provided with a second channel protrusion 4331. The outer wall of the columnar part 42 is provided with a columnar part protrusion 421, which is in cooperation with the inner wall of the base protrusion 24 to achieve a reliable connection between the two without shaking. The spring piece 49 includes a spring piece protrusion 491 that matches the outer bottle groove 12. The spring piece protrusion 491 is fastened to the outer bottle groove 12 to keep the replacement part 7 above the positioning block 4. During installation, the spring piece protrusion 491 moves upward, passes through the clearance notch 11, and then fastens into the outer bottle groove 12. The clearance notch 11 serves a positioning and guiding function. The upper end of the columnar part 42 and the positioning disc body 41 together form a disc body notch 44. The disc body notch 44 connects to the guide channel 43. The disc body notch 44 includes a notch protrusion 441 extending inward.

[0048] Reference Figure 12 The guide post 5 includes a post body 51 and a guide post ring 52 located at the top of the post body 51. The guide post ring 52 is located above the inner protrusion 47, and the outer contour of the guide post ring 52 extends beyond the outer contour of the inner protrusion 47. The outer wall of the post body 51 is provided with a protruding guide head 53. The guide head 53 extends into the guide channel 43 and can move along the guide channel 43. There are two guide heads 53 and two guide channels 43. When the guide head 53 is located at the end of the first channel 431, it is restricted by the second channel protrusion 4331. When the guide head 53 is located at the end of the third channel 433, it is restricted by the second channel protrusion 4331. The rotation angle of the guide head 53 from the end of the first channel 431 to the end of the third channel 433 is 180 degrees. Figure 3The inner wall of the column 51 is provided with a guide post inner protruding ring 54, and the guide head 53 passes through the guide channel 43 and extends into the base channel 223. Since a pair of clamping plates 23 clamp one guide head 53, rotating the base 2 can drive the guide head 53 to move along the guide channel 43. The upper and lower ends of the spring 8 abut against the guide post inner protruding ring 54 and the central protruding post step 331, respectively. Through the force of the spring 8, the side strip protrusion 34 can reliably abut against the buckle 251 downwards.

[0049] Reference Figure 13 The top plate 6 includes an elliptical plate body 62, a top plate protrusion 61 located below the plate body 62, and an insert block 63 located above the plate body 62. The lower end face of the plate body 62 abuts against the upper end of the outer protrusion 46. The outer edge of the top plate protrusion 61 is provided with an outwardly protruding protrusion ring 611. (Refer to...) Figure 3 The inner convex ring 54 of the guide post is located above the convex ring 611, and the inner diameter of the inner convex ring 54 is smaller than the outer diameter of the convex ring 611. When the top plate 6 is installed into the guide post 5, the inner convex ring 54 of the guide post is pressed by the convex ring 611 and passes through the inner convex ring 54 to achieve the installation and positioning of the two. The insert 63 passes through the bottom plate hole 721, and the insert 63 and the bottom plate hole 721 have a certain tight fit relationship, so that the replacement part 7 will not fall out when the entire packaging bottle is inverted.

[0050] Reference Figure 3 When the guide head 53 is located in the first channel 431, the upper end of the guide post 5 does not contact the top plate 6. The spring tab protrusion 491 is restricted by the top plate 6 and cannot disengage from the outer bottle groove 12. Specifically, the horizontal gap between the outer edge of the plate 62 and the location of the spring tab protrusion 491 is small. For the spring tab protrusion 491 to disengage from the outer bottle groove 12, it must deform horizontally inward. However, the small horizontal gap between the two prevents the spring tab protrusion 491 from disengaging from the outer bottle groove 12, thus forming a locked state. (Refer to...) Figure 5 When the guide head 53 is located in the third channel 433, the guide post ring 52 abuts against the plate 62 and the top plate 6 disengages from the positioning block 4. The pressing of the pressing block 3 causes the side strip 32 to move toward the location of the spring piece 49, which can abut against the spring piece 49 and cause the spring piece protrusion 491 to disengage from the outer bottle groove 12.

[0051] Reference Figure 3 The positioning block 4 supports the replacement part 7 via the top plate 6.

[0052] The pressing block 3 can move toward the location of the spring piece 49 to abut against the spring piece 49 and cause the spring piece protrusion 491 to disengage from the outer bottle groove 12. With the spring piece protrusion 491 disengaged from the outer bottle groove 12, the base 2, pressing block 3, positioning block 4 and replacement part 7 can be detached from the bottom of the outer bottle 1.

[0053] The method for replacing the packaging bottle includes the following steps:

[0054] a. Rotate the base 2 180 degrees. At this time, the pressing block 3 rotates 180 degrees synchronously with the base 2. During the rotation, the guide head 53 of the guide post 5 moves from the first channel 431 of the positioning block 4 to the third channel 433. The guide post 5 is lifted and pushes the replacement part 7 upward against the top plate 6, so that the top plate 6 moves away from the positioning block 4. At this time, the nozzle 76 is exposed in the middle hole 14 of the outer bottle. This process is to release the constraint of the top plate 6 on the positioning block 4.

[0055] b. Push the pressing block 3 upward, the side strip 32 passes through the top plate notch 221 of the base 2 and abuts against the spring piece 49, the spring piece 49 deforms inward so that the spring piece protrusion 491 disengages from the outer bottle groove 12;

[0056] c. Disconnect the base 2, pressing block 3, and positioning block 4 from the bottom of the outer bottle 1. At this time, the replacement part 7 also disconnects from the bottom of the outer bottle 1.

[0057] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
