[0059] like Figures 1 to 13 As shown, the adjustable discharge packaging bottle of this embodiment includes: an outer bottle 1, an inner bottle assembly 2, and a bottom cap 3.

[0060] The outer bottle 1 has a discharge nozzle 11 at one end (bottom end) and two symmetrically arranged stop grooves 12 on the inner circumference of the other end (top end) of the outer bottle 1. The stop grooves 12 have notches 101 formed on the inner wall of the end face of the outer bottle 1.

[0061] The inner bottle assembly 2 includes: inner bottle 21, cap 22, piston 23, pump cover 24, and pump core 25.

[0062] A pump cap 24 is mounted on the opening of the inner bottle 21, forming a detachable fixed connection between the pump cap 24 and the inner bottle 21. A pump core 25 is fixedly mounted on the pump cap 24, with one end (top) of the pump core 25 extending into the inner bottle 21 and the other end (bottom) extending out of the opening of the inner bottle 21. The pump cap 24 and pump core 25 seal the opening of the inner bottle 21, storing the cosmetic material inside the inner bottle 21.

[0063] The piston 23 is slidably disposed inside the inner bottle 21, and the outer circumferential wall of the piston 23 forms a sealed connection with the inner wall of the inner bottle 21.

[0064] The cap 22 is connected to the bottom of the inner bottle 21, and the cap 22 and the inner bottle 21 are detachably connected.

[0065] The outer circumference of the inner bottle 21 is symmetrically provided with two gear control ribs 211.

[0066] The inner bottle 21 is slidably fitted onto the inner circumference of the outer bottle 1. The bottom end of the pump core 25 is detachably connected to the outlet 11 of the outer bottle 1, and the outlet channel of the pump core 25 is connected to the outlet channel of the outlet 11 of the outer bottle 1. The two position control ribs 211 of the inner bottle 21 are inserted into the two position slots 12 of the outer bottle 1 from the notch 101 of the outer bottle 1, respectively. The position control ribs 211 can slide axially up and down in the position slots 12, and the position slots 12 can adjust the up and down sliding stroke of the position control ribs 211.

[0067] The bottom cap 3 is detachably attached to the outer bottle 1 to cover and close the discharge nozzle 11 of the outer bottle 1.

[0068] In this embodiment, when the cap is pressed under external force, it causes the inner bottle's position control rib to slide downwards within the outer bottle's position groove. Simultaneously, the cap causes the inner bottle to slide downwards, which in turn causes the pump cap and pump core to move downwards, compressing the spring within the pump core. When the cap is released, the inner bottle and pump core move upwards to reset under the action of the spring within the pump core. Continuously pressing the cap causes the pump core to move up and down, thereby pumping out the cosmetic material from the inner bottle. The pumped cosmetic material flows out from the outlet of the outer bottle.

[0069] The adjustable slot of the outer bottle controls the downward stroke of the control rib, which controls the pressing stroke of the pump core (cap), thereby controlling the discharge amount of the material.

[0070] The inner bottle components are assembled to form a replacement pack. After the cosmetic product in the inner bottle is used up, the inner bottle component is removed from the outer bottle, and then a new inner bottle component is assembled onto the outer bottle, thus completing the replacement of the inner bottle component (replacement pack).

[0071] As can be seen from the above, the adjustable discharge packaging bottle of this embodiment is provided with an outer bottle, an inner bottle assembly, and a bottom cap. The outer bottle is provided with a discharge nozzle and a stop groove. The inner bottle assembly includes an inner bottle, a pressure cap, a piston, a pump cover, and a pump core. The pump cover is located at the mouth of the inner bottle, the pump core passes through the pump cover, the piston is located inside the inner bottle, the pressure cap is connected to the inner bottle, the inner bottle is provided with a stop control rib, the inner bottle is slidably fitted inside the outer bottle, the pump core is detachably connected to the discharge nozzle, and the stop control rib of the inner bottle is slidably embedded in the stop groove of the outer bottle. In this embodiment, the adjustable-discharge packaging bottle features a cap that, when pressed, allows the inner bottle's adjustable rib to slide up and down within the outer bottle's adjustable groove. Simultaneously, the inner bottle drives the pump core to move up and down, pumping out the cosmetic material from the inner bottle. The adjustable groove on the outer bottle controls the downward stroke of the adjustable rib, thus controlling the pump core's pressing stroke and controlling the discharge amount. This allows consumers to choose the amount of material dispensed, enhancing their consumer experience. The inner bottle assembly is replaceable, reducing packaging material waste and lowering costs.

[0072] Optional, such as Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, the adjustable discharge volume packaging bottle has an outer bottle 1 with a slot 12 including a vertical slot 121 and a horizontal slot 122.

[0073] The vertical groove 121 extends along the axial direction of the outer bottle 1. There are multiple vertical grooves 121, which are spaced apart on the inner wall of the outer bottle 1. The tops of two adjacent vertical grooves 121 are connected by a horizontal groove 122.

[0074] The lengths of the multiple vertical grooves 121 in the axial direction are all different. The lengths of the multiple vertical grooves 121 in the axial direction are arranged to decrease (or increase) in sequence. The longest vertical groove 121 extends upward and penetrates the end face of the outer bottle 1, forming a notch 101 on the end face of the outer bottle 1. The notch 101 allows the position control rib 211 of the inner bottle 21 to be inserted, so that the position control rib 211 enters the position groove 12 of the outer bottle 1.

[0075] In this embodiment, the slots of the outer bottle include multiple vertical slots of different lengths, such as two vertical slots, long (large) and short (small), in this embodiment; or three vertical slots, long (large), medium (medium) and short (small); or four vertical slots, etc.

[0076] When the inner bottle assembly is inserted into the outer bottle, the inner bottle's positioning control rib inserts into the outer bottle's positioning groove through the longest vertical slot. Rotating the cap allows the positioning control rib to be positioned in vertical slots of different lengths within the positioning groove, resulting in varying descent strokes of the cap and pump core. When the positioning control rib is in the longest vertical slot (larger setting), the cap and pump core descent stroke is greater, resulting in a larger output per pump cycle. Conversely, when the positioning control rib is in the shortest vertical slot (smaller setting), the cap and pump core descent stroke is shorter, resulting in a smaller output per pump cycle, thus controlling the pump core's output.

[0077] Furthermore, in this embodiment, the adjustable discharge volume packaging bottle, the outer bottle 1's slot 12 also includes a locking slot 123.

[0078] The locking groove 123 is located close to the shortest vertical groove 121. The locking groove 123 is connected to the shortest vertical groove 121 through the horizontal groove 122. The height of the locking groove 123 corresponds to the height of the gear control rib 211 of the inner bottle 21. It is used to allow the gear control rib 211 to be embedded and to prevent the gear control rib 211 from sliding in the axial direction of the outer bottle 1.

[0079] It should be noted that the locking groove 123 can also be set close to the longest vertical groove 121 and connected to the longest vertical groove 121 through the horizontal groove 122.

[0080] In this embodiment, the locking groove and the vertical groove of the position groove are connected by a horizontal groove. When the cap is rotated, and the position control rib of the inner bottle enters the locking groove from the position groove, the movement of the cap (position control rib) in the axial direction of the outer bottle is stopped. At this time, the pump core is locked to prevent the cap from being accidentally pressed, which would cause the cosmetic material to be pumped out and wasted.

[0081] Furthermore, in this embodiment, the packaging bottle with adjustable discharge volume has an arc-shaped stop 124 at the horizontal groove 122 connecting two adjacent vertical grooves 121 and at the horizontal groove 122 connecting the locking groove 123 and the shortest vertical groove 121.

[0082] In this embodiment, when the pressure cap is rotated and the inner bottle's gear control rib enters the vertical groove of different gears, there will be a jolt, achieving precise adjustment of different gears; and the arc-shaped stop block blocks the gear control rib, preventing the gear control rib from automatically sliding out of the vertical groove of the gear being used.

[0083] Furthermore, in this embodiment, the packaging bottle with adjustable discharge volume has an indicator mark 13, such as a LOGO, on the outer wall of the outer bottle 1.

[0084] The pressure cap 22 has multiple position markings 221 and a lock marking 222 on the outer circumference of the end face. The position markings 221 correspond to the discharge volume.

[0085] Rotating the cap 22 causes the inner bottle 21 to rotate. When the position mark 221 or lock mark 222 of the cap 22 aligns with the indicator mark 13 (LOGO) of the outer bottle 1, the position mark 221 or lock mark 222 indicates the position of the position control rib 121: if the large position mark of the cap aligns with the indicator mark, the position control rib is in the long vertical groove of the position groove; if the small position mark of the cap aligns with the indicator mark, the position control rib is in the short vertical groove of the position groove; if the lock mark of the cap aligns with the indicator mark, the position control rib is in the locking groove of the position groove.

[0086] Optional, such as Figure 11 and Figure 12 As shown, in this embodiment, the adjustable discharge packaging bottle has a first limiting groove 212, a first fastening groove 213 and a vent hole 214 on the inner wall of the top circumference of the inner bottle 21. The first limiting groove 212 is arranged along the axial direction of the inner bottle 21, and the first vent hole 214 is located below the gear control rib 211.

[0087] The outer circumferential wall of the pressure cover 22 is provided with a first limiting rib 223 and a first fastening block 224, and multiple first fastening blocks 224 are evenly distributed along the circumferential direction of the pressure cover 22.

[0088] When the cap 22 is connected to the inner bottle 21, the first limiting rib 223 of the cap 22 is inserted into the first limiting groove 212 of the inner bottle 21, and the first fastening block 224 of the cap 22 is fastened into the first fastening groove 213 of the inner bottle 21, so that the cap 22 and the inner bottle 21 form a detachable fastening connection.

[0089] The vent 214 of the inner bottle 21 connects the piston 23 inside the inner bottle 21 with the atmosphere. As the amount of material inside the inner bottle 21 decreases, the piston 23 slides downward under the action of the atmosphere, pushing the material inside the inner bottle 21 toward the bottle opening, so that the cosmetic material is pumped out more thoroughly and waste is reduced.

[0090] Optionally, in this embodiment, the inner bottle assembly 2 of the packaging bottle with adjustable discharge volume further includes a sealing gasket 26.

[0091] The sealing gasket 26 is fitted onto the pump core 25. When the pump cover 24 is connected to the inner bottle 21, the sealing gasket 26 abuts against the bottle mouth end face of the inner bottle 21, making the inner bottle 21 more sealed.

[0092] Optionally, in this embodiment, the packaging bottle with adjustable discharge volume has a second groove 241 on the inner circumferential wall of the pump cover 24.

[0093] The inner bottle 21 has a second buckle 215 at its mouth.

[0094] When the pump cover 24 is connected to the inner bottle 21, the second buckle 215 of the inner bottle 21 engages with the second buckle groove 241 of the pump cover 24, so that the inner bottle 21 and the pump cover 24 form a detachable buckle connection.

[0095] Optionally, in this embodiment, the adjustable discharge packaging bottle has a third groove 251 provided in the pump core 25.

[0096] The outer bottle 1 has a connecting post 111 at the discharge nozzle 11, and the outer circumferential wall of the connecting post 111 has a third buckle 112.

[0097] When the outer bottle 1 is connected to the pump core 25, the connecting post 111 of the outer bottle 1 is inserted into the pump core 25, so that the third buckle 112 on the connecting post 111 is engaged with the third buckle groove 251 of the pump core 25, and the outer bottle 1 and the pump core 25 form a detachable buckle connection.

[0098] Furthermore, in this embodiment, the packaging bottle with adjustable discharge volume has multiple arc-shaped protrusions 14 on the outer wall of the outer bottle 1 at the discharge nozzle 11, and the multiple arc-shaped protrusions 14 are evenly distributed along the circumference of the outer bottle 1.

[0099] The inner wall of the bottom cover 3 is provided with a fourth groove 31, and the bottom cover 3 is provided with a sealing head 32.

[0100] When the bottom cap 3 is closed, the arc-shaped protrusion 14 of the outer bottle 1 is embedded in the fourth snap groove 31 of the bottom cap 3, and the outer bottle 1 and the bottom cap 3 form a detachable snap connection. At the same time, the sealing head 32 of the bottom cap 3 is inserted into the discharge channel of the discharge nozzle 11 of the outer bottle 1, making the discharge channel of the discharge nozzle 11 more sealed.

[0101] When the adjustable discharge bottle of this utility model is in the closed state and not in use, the cap is in the locking position (the position control rib of the inner bottle is located in the locking groove of the position groove), and the pump core is locked.

[0102] When using, remove the bottom cap, rotate the cap to select the large or small setting, and then press the cap to dispense the material from the outlet of the outer bottle. After use, rotate the cap back to the locked position.

[0103] Once all the cosmetic material in the inner bottle has been used up, rotate the cap to the highest setting, pull the cap off forcefully, remove the inner bottle assembly from the outer bottle, and then install the new inner bottle assembly (replacement pack) to complete the replacement of the inner bottle assembly.
