The inner bottle is configured to pop out of the outer bottle 60 by pressing the second button.

The shape of the cosmetic bottle is not limited herein, and can be square, round, or various special shapes. The cosmetic bottle is suitable for various liquid cosmetics. From the outside, the cosmetic bottle includes an upper part being the cover 10, and a lower part being the outer bottle 60. The first inner connecting member is fixedly connected into the cover 10. The first inner connecting member and the cover can be fixedly connected by glue. The first button is placed on the upper opening end of the first inner connecting member and is limited in the cover 10. The brush rod 40 is located below the first button. The first button and the brush rod are in contact with each other. The first button can move up and down along the first inner connecting member. When the first button is pressed, the brush rod 40 moves downward as a whole and protrudes from the cover 10. The brush rod 40 is pulled out from the cover by holding the protruding part of the brush rod. The inner bottle 50 is used for storing cosmetic materials. The clamping ring 70 is sleeved on the outer side of the lower connecting portion 53 at the lower end of the inner bottle. The clamping ring and the lower connecting portion are fixedly connected by glue. The second inner connecting member is placed at the lower opening end of the outer bottle 60. The second inner connecting member is placed head down at the lower end of the outer bottle. The second inner connecting member and the outer bottle are fixedly connected by glue. The second button is arranged at the opening end of the second inner connecting member. The second button is stopped in the outer bottle. The inner bottle 50 is loaded into the outer bottle 60, and the clamping ring 70 is inserted into the second inner connecting member and is in contact with the second button. When the second button is pressed, the second button pushes the inner bottle 50 to move upward to protrude from the outer bottle 60, and the inner bottle is taken out from the outer bottle by holding the protruding part of the inner bottle. Therefore, in the present invention, the internal components in contact with the materials, that is, the brush rod and the inner bottle, can be replaced. If the cosmetic materials in the old and new inner bottles are the same, it is only necessary to replace the inner bottle, and other components can be used repeatedly. If the brush rod is damaged, it is only necessary to replace the brush rod. If the cosmetic materials used are different, the brush rod and the inner bottle can be both replaced, so the present invention can meet various use needs, and has stronger practicability and wider application range.

As shown in FIG. 2 and FIG. 3, both an upper end and a lower end of the cover 10 are opening ends, the upper opening end of the cover 10 extends radially inward to form a stop ring, and the stop ring extends downward to form a first stop rod 11. The first stop rod 11 is parallel to the cover, a certain gap is formed therebetween, and the upper end of the first inner connecting member is inserted into the gap. The button 20 includes a stop portion 21 and an extrusion portion 22, and an inner side of the extrusion portion 22 is an inclined surface. Under normal conditions, the stop portion 21 on the first button abuts against the inner side of the first stop rod 11 on the cover, and the first button is restrained in the cover. The upper end of the cover is an opening end, so the first button can be directly pressed from the upper end of the cover.

As shown in FIG. 4 to FIG. 6, the inner connecting member 30 is a hollow member with openings at both ends, an inner side of the inner connecting member 30 extends radially inward to form a boss 31 and a clamping rib 32, and the boss 31 is located above the clamping rib 32. A gap is formed between the head 41 and the rod body 44 of the brush rod, an internal thread 42 is formed in an inner side of the head, two symmetrical first elastic members 43 are arranged on an upper end of the head 41, first hooks 46 are respectively arranged at heads of the first elastic members 43, a gap is formed between the two first hooks 46, and an outer side of each of the first hooks 46 is an inclined surface. The boss on the first inner connecting member is used to limit the first hook on the first elastic member of the brush rod. Under normal conditions, the first hook 46 on the first elastic member is stopped by the boss, the first hook is placed in the first button, and its inclined surface abuts against the inclined surface of the extrusion portion of the first button. When the first button is pressed, the inclined surface of the first button applies pressure to the inclined surface of the first hook, such that the two first hooks move inward, then the first hooks slide out of the boss, and the brush rod 40 can move downward. When moving to the clamping rib 32, the first hook is blocked by the clamping rib, the head of the brush rod has protruded from the lower opening end of the cover, and the brush rod is directly pulled out, so the clamping rib here acts as a buffer to prevent the brush rod from directly popping out of the cover under the action of the button. After the old brush rod is taken out, a new one is loaded so as to complete the replacement of the brush rod. The specific principle of extruding the brush rod by the first button is as follows: a gap is formed between the first hook on the first elastic member 43 and the inner wall of the first inner connecting member, the first button is inserted into the gap, and the inclined surface of the first button fits the inclined surface of the first hook 46. Therefore, when the first button is pressed downward, the two inclined surfaces are pressed together to apply horizontal component force to the first hook, such that the two first hooks are compressed inward and slide over the boss 31 of the first inner connecting member.

As shown in FIG. 7 and FIG. 8, the upper connecting portion 51 and the lower connecting portion 53 are arranged at the upper end and the lower end of the inner bottle 50 respectively, and an external thread 52 is formed in an outer side of the upper connecting portion 51. During assembly, the upper connecting portion of the inner bottle is inserted into the gap between the head and the rod body of the brush rod, and is screwed with the internal thread on the brush rod through the external thread, and the inner bottle is used for filling cosmetic materials. An inner plug 54 is nested at an inner side of an opening of the upper connecting portion 51, and the inner plug is fixed to the upper connecting portion by a snap ring. A circular snap ring is arranged on the outer side of the inner plug, and a circular groove is formed in the inner side of the inner bottle. When the inner plug is nested in the inner bottle, the snap ring is snapped into the groove to seal the inner bottle and the inner plug.

As shown in FIG. 11, the clamping ring 70 includes a mounting portion 71 and a second elastic member 72, the mounting portion 71 is sleeved on and fixedly connected to the lower connecting portion 53 of the inner bottle, two symmetrical second elastic members 72 are arranged on a lower end of the mounting portion 71, second hooks 73 are respectively arranged at heads of the second elastic members 72, a gap is formed between the two second hooks 73, and an outer side of each of the second hooks 73 is an inclined surface. Specifically, the mounting portion is fixedly connected to the lower connecting portion by glue, and the boss 31 on the second inner connecting member is used to limit the second hook 73 on the second elastic member of the clamping ring. Under normal conditions, the second hook is stopped by the boss, the second hook is placed in the second button, and its inclined surface abuts against the inclined surface of the extrusion portion of the second button. When the second button is pressed, the inclined surface of the second button applies pressure to the inclined surface of the second hook, such that the two second hooks move inward, then the second hooks slide out of the boss, and the inner bottle 50 can move upward. When moving to the clamping rib 32, the second hook is blocked by the clamping rib, the upper connecting portion of the inner bottle has protruded from the upper opening end of the outer bottle, and the inner bottle is directly pulled out, so the clamping rib here acts as a buffer to prevent the inner bottle from directly popping out of the outer bottle under the action of the second button. After the old inner bottle is taken out, a new one is loaded, so as to complete the replacement of the inner bottle. The specific principle of extruding the clamping ring by the second button is as follows: a gap is formed between the second hook 73 and the inner wall of the second inner connecting member, the second button is inserted into the gap, and the inclined surface of the second button fits the inclined surface of the second hook 73. Therefore, when the second button is pressed upward, the two inclined surfaces are pressed together to apply horizontal component force to the second hook, such that the two second hooks are compressed inward and slide over the boss 31 of the second inner connecting member.

As shown in FIG. 10, both an upper end and a lower end of the outer bottle 60 are opening ends, the lower opening end of the outer bottle 60 extends radially inward to form a second stop ring, and the second stop ring extends upward to form a second stop rod 61. The second stop rod 61 is parallel to the outer bottle, a certain gap is formed therebetween, and the upper end of the second inner connecting member is inserted into the gap. Under normal conditions, the stop portion 21 on the second button abuts against the inner side of the second stop rod 61 on the outer bottle, and the second button is restrained in the outer bottle. The lower end of the outer bottle is an opening end, so the second button can be directly pressed from the lower end of the outer bottle.

As shown in FIG. 5 and FIG. 12 to FIG. 15, a mounting groove 45 is formed in the other end of the rod body 44 of the brush rod, the brush head 80 is fixedly arranged in the mounting groove 45, and the brush head is a plastic brush head 81, an iron wire brush head 82, a cotton brush head 83, or an eyeliner brush head 84. Therefore, the cosmetic bottle can be applied to water-based liquid cosmetics such as essence and eyeliner, or oily liquid cosmetics such as essential oil and lip oil, and is widely used.
