[0043] like Figures 1 to 4 As shown, an embodiment of this utility model provides a cosmetic packaging bottle with a replaceable vacuum bag, including an outer cup 1, a pressing part 2, a connecting part 3, a pressing vacuum pump 4, and a replacement liner 5; the replacement liner 5 includes an inner cup 51, an outer liner 52, and a bag-type inner liner 53 located inside the outer liner 52, the bottle mouth of the bag-type inner liner 53 passes through the bottle mouth of the outer liner 52 and is snapped into the bottle mouth of the outer liner 52, the outer liner 52 is placed inside the inner cup 51; the replacement liner 5 can be placed inside the outer cup 1 and snapped into the outer cup 1; The connecting part 3 is threadedly connected to the bottle mouth of the outer liner 52 and covers the bottle mouth of the outer cup 1; the press-type vacuum pump 4 extends through the connecting part 3 into the bottle mouth of the bag-type inner liner 53 and is press-fitted with the bottle mouth of the bag-type inner liner 53; the press-type vacuum pump 4 is snapped into the connecting part 3; the press-type vacuum pump 4 has a flow channel 401 communicating with the bag-type inner liner 53; the pressing part 2 is located at the end of the press-type vacuum pump 4 away from the replacement liner 5; the pressing part 2 has a liquid outlet channel 201 communicating with the flow channel 401.
[0044] In this embodiment, the pouch-type inner liner 53 is a blow-blown bottle with a certain degree of elasticity. The press-type vacuum pump 4 passes through the connecting part 3 and is snapped into place. During the threaded connection between the connecting part 3 and the outer liner 52, the press-type vacuum pump 4 is inserted into the bottle mouth of the pouch-type inner liner 53 and forms an interference fit with the bottle mouth of the pouch-type inner liner 53 to achieve an elastic seal between the press-type vacuum pump 4 and the bottle mouth of the pouch-type inner liner 53. This improves the feel of the press-type vacuum pump 4 being screwed into the bottle mouth of the pouch-type inner liner 53 and provides good sealing. Pressing the press-type vacuum pump 4 in this embodiment allows the cosmetics inside the pouch-type inner liner 53 to flow out through the flow channel 401 and the liquid outlet channel 201 under vacuum.
[0045] like Figure 5 As shown, this embodiment also includes a cap 6, which is threadedly connected to the outer liner 52 of the replacement liner 5. The cap 6 and the replacement liner 5 constitute a replacement package for the cosmetic packaging bottle with a replaceable vacuum bag in this embodiment. When replacement is needed, the cap 6 is unscrewed, so that the outer liner 52 of the replacement liner 5 is threadedly connected to the connecting part 3.
[0046] The cosmetic packaging bottle with replaceable vacuum bags of this embodiment is suitable for creams and other materials with similar physical states. The vacuum bag in this embodiment refers to a bag that is in a vacuum state during use.
[0047] Furthermore, such as Figure 4 and Figure 6 As shown, the push-button vacuum pump 4 includes a pump body 41, a pump core 42, a spring 43, a first limiting part 44, and a second limiting part 45. The pump body 41 has a cavity with an open upper end. A first through hole is provided at the center of the bottom wall of the cavity. The lower end of the pump core 42 is engaged in the pump body 41 and can move along the axis of the pump body 41. A second through hole communicating with the first through hole is provided through the axis of the pump core 42. The second through hole communicates with the liquid outlet channel 201. The first through hole and the second through hole form a flow channel 401. The pump body 41 passes through the connecting part 3 and is inserted into the bag-type inner... The inner liner 53 is inserted into the bottle mouth and is press-fitted with the bottle mouth of the bag-type inner liner 53. The first limiting part 44 is engaged with the upper end of the pump body 41 and extends to protrude from the outer periphery of the pump body 41. The first limiting part 44 is located at the upper end of the connecting part 3. The second limiting part 45 is engaged with the pump core 42. The pressing part 2 is engaged with the second limiting part 45. The second limiting part 45 and the pump core 42 can move up and down relative to the pump body 41 and the first limiting part 44. The lower end of the spring 43 abuts against the first limiting part 44, and the upper end of the spring 43 abuts against the second limiting part 45.
[0048] In this embodiment, the pump body 41 passes through the connecting part 3 and is inserted into the bottle opening of the bag-type inner liner 53. The pump body 41 and the bottle opening of the bag-type inner liner 53 are rigidly fitted together, thereby achieving an elastic sealing connection. When the pressing part 2 is pressed down, the pressing part 2 pushes the pump core 42 to move towards the bottom wall of the cavity of the pump body 41 against the force of the spring 43; when the pressing part 2 is released, the spring 43 returns to its original position, and the pump core 42 moves upward under the action of the spring 43.
[0049] For example, the lower end of the pump body 41 has a conical structure, that is, the diameter of its lower end is smaller than the diameter of the sealing connection area between the pump body 41 and the bottle mouth of the bag-type inner liner 53. This structural design can reduce the difficulty of interference fit between the pump body 41 and the bottle mouth of the bag-type inner liner 53 and improve assembly efficiency.
[0050] Furthermore, the first limiting part 44 has a first limiting groove with its opening facing upwards, and the second limiting part 45 has a second limiting groove with its opening facing downwards. Both ends of the spring 43 abut against the bottom of the first and second limiting grooves, respectively. This limiting groove structure design improves the installation stability of the spring 43 and prevents its misalignment from affecting the pressing and dispensing effect of the press-type vacuum pump 4. The first limiting part 44 has a snap-fit hole on its axis that communicates with the second through hole, and this snap-fit hole engages with the pressing part 2.
[0051] The press-type vacuum pump 4 also includes a snap-fit structure 46 surrounding the inner wall of the pump body 41. The snap-fit structure 46 has a slot on each of its upper and lower sides. The bottom of the pump core 42 has a first hook that folds outward and extends upward. This snap-fit structure 46 allows the pump core 42 to press against the snap-fit structure 46 from the upper opening of the pump body 41 and move downward until it is engaged with the lower end of the snap-fit structure 46. Specifically, the first hook engages with the slot on the lower side of the snap-fit structure 46, preventing the pump core 42 from separating from the pump body 41. The outer periphery of the pump core 42 also has a second hook, which engages with the slot on the upper side of the snap-fit structure 46, thus engaging the pump core 42 with the snap-fit structure 46. By pressing the pressing part 2, the pump core 42 can be driven to slide the snap-fit structure 46 relative to the pump body 41.
[0052] Furthermore, such as Figure 7 As shown, the bottle mouth end of the pouch-type inner liner 53 has a stop portion 531 extending radially outward along the bottle mouth. When the pouch-type inner liner 53 is located inside the outer liner 52, the stop portion 531 is located outside the bottle mouth of the outer liner 52 and contacts the end face of the bottle mouth of the outer liner 52. When the pump body 41 is inserted into the bottle mouth of the pouch-type inner liner 53, it can prevent the pump body 41 from squeezing and deforming the bottle mouth of the pouch-type inner liner 53 and shrinking it into the outer liner 52.
[0053] Furthermore, such as Figure 4 As shown, the connecting part 3 includes a connecting part body 31, an internal threaded component 32, a first snap-fit ring 33, and a second snap-fit ring 34. The connecting part body 31 has a through hole through which the pump body 41 passes. The internal threaded component 32 is located at the lower end of the connecting part body 31 and is coaxial with the through hole. The internal threaded component 32 is screwed into the bottle neck of the outer liner 52. The upper end of the connecting part body 31 is provided with a first snap-fit ring 33 and a second snap-fit ring 34. The first snap-fit ring 33 and the second snap-fit ring 34 are coaxial. The outer diameter of the first snap-fit ring 33 is smaller than the outer diameter of the second snap-fit ring 34. The inner wall of the first snap-fit ring 33 is engaged with the first limiting part 44. The outer edge of the pressing part 2 extends into the gap between the first snap-fit ring 33 and the second snap-fit ring 34.
[0054] Specifically, the inner circumference of the first locking ring 33 is provided with a protrusion, the lower end of the first limiting part 44 abuts against the upper end face of the connecting part 3, and the outer circumference of the first limiting part 44 is locked on the lower side of the protrusion. This locking structure 46 is used to improve the installation stability of the pump core 42.
[0055] like Figure 8As shown, the pressing part 2 includes a pressing cover 21, a connecting pipe 22, and a liquid outlet pipe 23. The connecting pipe 22 is fixed inside the outer cover 7 and located at the bottom of the outer cover 7. The liquid outlet pipe 23 is arranged laterally and extends to protrude from the outer side of the pressing cover 21. The pressing cover 21 has a channel communicating with the liquid outlet pipe 23 and the connecting pipe 22, thereby forming a liquid outlet channel 201. The outer periphery of the connecting pipe 22 is provided with a protrusion, and a corresponding annular groove is provided on the inner wall of the second through hole of the pump core 42. The annular groove is adjacent to the upper end of the pump core 42. The connecting pipe 22 is inserted into the second through hole, and the connection between the connecting pipe 22 and the pump core 42 is achieved by the cooperation of the protrusion and the annular groove.
[0056] In addition, the pressing part 2 also includes a plurality of reinforcing ribs 24, all of which are distributed along the circumference of the connecting tube 22. The reinforcing ribs 24 are respectively connected to the bottom of the pressing cover 21 and the outer periphery of the connecting tube 22, thereby improving the structural stability of the connecting tube 22.
[0057] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the cosmetic packaging bottle with replaceable vacuum bag in this embodiment also includes an outer cover 7, which covers the upper end of the pressing part 2 and abuts against the outer wall of the second snap ring 34.
[0058] The outer cover 7 is installed on the upper end of the pressing part 2 to keep the outlet of the liquid outlet pipe 23 of the pressing part 2 clean. The outer cover 7 abuts against the outer wall of the second snap ring 34, making it easy to remove and fasten the outer cover 7.
[0059] In order to reduce the production cost of molds, this embodiment adopts a split structure design for the outer cover 7, that is, the outer cover 7 includes an outer cover body 71 located in the circumferential direction and a cover 72 located on the top of the outer cover body 71, and the cover 72 is snapped into the outer cover body 71.
[0060] Furthermore, the pouch-type inner liner 53 can be detachably installed inside the outer liner 52. Through the detachable structural design, the pouch-type inner liner 53 can be quickly installed into the outer liner 52.
[0061] For example, such as Figure 2 , Figures 9 to 11 As shown, the outer liner 52 includes two circumferentially distributed sub-liners 521, which are detachably connected. Specifically, the cross-sections of the two sub-liners 521 are semi-circular. After they are connected, the external threads of the bottle openings of the sub-liners 521 can match the internal threads of the connecting part 3 without affecting the screw-on connection.
[0062] Furthermore, the two sub-blanks 521 are snap-fitted together between two sets of opposite sides along the circumference of the outer blank 52, and one set of sides is rotatably connected by a rotating part 522, the rotation axis of the rotating part 522 extending in the vertical direction.
[0063] It is understandable that when the latch between the two sub-blades 521 is released, a set of sides of the two sub-blades 521 are still connected by the rotating part 522. After the pouch-type inner liner 53 is placed tightly against one of the sub-blades 521, the other sub-blades 521 is rotated to latch with it, thus completing the assembly of the inner liner. In this embodiment, the outer liner 52 adopts this rotating and latching structure, which can improve the assembly efficiency of the inner liner.
[0064] Specifically, the two sub-blanks 521 are engaged on two opposing sets of sides along the circumference of the outer blank 52 using a locking rod 523 and a locking groove 524, the details of which will not be elaborated further. The locking rod 523 and the locking groove 524 are located on the inner side of the top wall of the sub-blank 521.
[0065] Furthermore, along the circumference of the outer liner 52, there is a gap 525 between the two sub-liners 521, which extends to the lower end of the outer liner 52. The inner wall of the inner cup 51 is provided with a snap-fit strip 511 that corresponds one-to-one with the gap 525. The length of the snap-fit strip 511 extends in the vertical direction, and the snap-fit strip 511 snaps into the gap 525.
[0066] This embodiment makes full use of the gap 525 between the inner cups 521 and engages the gap 525 with the snap-fit strip 511 protruding from the inner wall of the inner cup 51 to prevent the inner cups 521 from shaking with the inner cup 51.
[0067] Furthermore, the bottom of the outer liner 52 is open, and two mounting notches 526 are spaced apart at the lower end of the outer liner 52. The top wall of each mounting notch 526 is connected to a first snap-fit part 527, which protrudes from the inner wall of the outer liner 52. The inner wall of the inner cup 51 is provided with a second snap-fit part 512 that corresponds one-to-one with the first snap-fit part 527. The second snap-fit part 512 is adjacent to the bottom wall of the inner cup 51. The bottom wall of the inner cup 51 is provided with a first clearance hole 513 that corresponds one-to-one with the second snap-fit part 512. The first snap-fit part 527 and the second snap-fit part 512 engage in a snap-fit cooperation.
[0068] After the outer liner 52 is inserted into the inner cup 51, in addition to the gap 525 between the inner liner 521 engaging with the snap-fit strip 511 on the inner wall of the inner cup 51, the first snap-fit part 527 is pressed down, causing the first snap-fit part 527 to extend into the first clearance hole 513 and engage with the second snap-fit part 512, thereby achieving a connection and further improving the assembly stability between the inner liner 521 and the inner cup 51.
[0069] Furthermore, the inner cup 51 has a folded portion 514 that folds outward and extends downward, and a groove is formed between the folded portion 514 and the side wall of the inner cup 51, so that the mouth of the outer cup 1 can be engaged in the groove. The outer periphery of the connecting portion 3 has a downward extending outer edge, which is adjacent to the outer periphery of the folded portion 514.
[0070] In this embodiment, the folding part 514 covers the mouth of the outer cup 1, making the cosmetic packaging bottle with replaceable vacuum bag more aesthetically pleasing; the mouth of the outer cup 1 is engaged with the groove, making disassembly and assembly convenient.
[0071] The groove bottom is provided with a second clearance hole 515, the folded part 514 is provided with a third locking part 516 protruding on the side opposite to the inner cup 51 side wall, the second clearance hole 515 and the third locking part 516 are positioned correspondingly, and the outer cup 1 is provided with a fourth locking part 11 protruding on the outer periphery of the cup mouth. Figure 2 During assembly, first offset the fourth locking part 11 from the third locking part 516, insert the inner cup 51 into the outer cup 1 until the mouth of the outer cup 1 is inserted into the groove, and then rotate the outer cup 1 so that the fourth locking part 11 and the third locking part 516 are locked together, thereby realizing the locking and fixing between the outer cup 1 and the inner cup 51.
[0072] The size of the cosmetic packaging bottle with replaceable vacuum pouch in this embodiment can be designed according to actual needs. For example, it can be designed with a capacity of 55±3mL, which is small, exquisite, easy to carry, and easy to use (finger-press).
