The embodiment is a quick-opening pipette bottle for use in a liquid cosmetic package. Referring to fig. 1 and 2, the quick-opening straw bottle of the present solution comprises a bottle 1, an inner cap 2, an outer cap 3, a button 4, a spring 5 and a straw assembly, wherein the straw assembly comprises a rubber cap 91, a straw 92 and a straw seat 93. The upper end of the bottle 1 is a bottle mouth, and an annular bottle mouth positioning groove 11 extends along the circumferential direction on the outer side wall of the bottle mouth. The inner cap 2 covers outside the bottle mouth, the main body of the button 4 is normally positioned above the inner cap 2, and the outer cap 3 covers outside the inner cap 2 and the button 4. The rubber cap 91 is fixed with the inner cap 2, the suction tube 92 is connected with the rubber cap 91, the suction tube seat 93 is buckled at the bottle mouth, and the suction tube 92 penetrates through the opening on the suction tube seat 93 and extends into the bottle mouth.

As shown in fig. 3 and 5, the inner cap 2 is a cylindrical structure provided with an inner cap side wall 21 and an inner cap top wall 26. The circumferential surface of the inner cap side wall 21 is provided with 3 fitting notches 27 in the circumferential direction, each fitting notch 27 corresponds to a central angle of 60 °, and the central angle corresponding to the gap between two adjacent fitting notches 27 is also 60 °. The mating notches 27 extend upwardly to the inner lid top wall 26. An inner lid spring 22 is provided in each fitting recess 27. The inner cover spring 22 is made of an elastic sheet material, the lower end of the inner cover spring is connected with the bottom edge of the matching notch 27, and the upper side, the left side and the right side of the inner cover spring are free. In normal condition, the inner side surface of the inner cap spring sheet 22 and the inner side surface of the inner cap side wall 21 are on the same cylindrical surface. A raised elastic piece convex rib 23 is designed on the inner side surface of the inner cover elastic piece 22 along the circumferential direction, the shape, the size and the position of the elastic piece convex rib 23 correspond to the bottle mouth positioning groove 11 in a matching manner, and the three elastic piece convex ribs 23 are embedded into the bottle mouth positioning groove 11 under a normal state to form a locking relationship between the inner cover and the bottle mouth. Inner cover reinforcing ribs 24 are arranged at the positions, close to the inner cover elastic sheets 22 on the two sides, of the inner side surfaces of the inner cover side walls 21. The inner cover reinforcing ribs 24 extend in the axial direction and the radial direction, and the lower ends thereof are provided with guide arc surfaces. The size of a virtual circle formed by the top surfaces of the six inner cover reinforcing ribs 24 in a surrounding mode corresponds to the outer diameter of the bottle mouth. The lower part of the outer side surface of the inner cover side wall 21 is provided with a circle of outer gear ring surface 25, and a circle of inner cover assembly limiting ring 28 which protrudes outwards is arranged below the outer gear ring surface 25. A rubber cap mounting hole 261 is formed through the inner cap top wall 26 for fitting the rubber cap 91.

As shown in fig. 4 and 5, the button 4 is in the shape of a cylinder with a closed top wall, and button claws 41 are provided extending downward below the side wall of the button 4, and the shape, size, position and number of the button claws 41 correspond to the fitting notches 27. The button claw 41 is inserted into the matching notch 27 in an axially matched manner, so that the button 4 can only move axially relative to the inner cover 2 and can not move circumferentially. In this embodiment, a latch slope 411 with a low inside and a high outside is provided at the lower end of the button latch 41, and the latch slope 411 has a low inside and a high outside. When the button 4 moves downwards, the claw slope 411 touches the end of the inner cap elastic sheet 22, the inner cap elastic sheet 22 is spread outwards through the claw slope 411, the elastic sheet convex rib 23 is separated from the bottle mouth positioning groove 11, and the locking relation between the inner cap and the bottle mouth is released. The lower end surface of the sidewall of the button 4 forms a stopper surface for axial movement, and when the button 4 moves downward, the lower end surface of the sidewall of the button 4 will eventually touch the upper end surface of the inner cap top wall 26. The outer side wall of the button 4 is convexly provided with a circle of button limiting ring 42.

The rubber cap 91 is made of elastic material and is shaped like a spherical capsule, and is arranged at the rubber cap mounting hole 261 through a groove below the outer side wall, and the body is deep into the lower part of the top wall of the button 4. The upper end of the suction tube 92 is hermetically connected with the opening of the rubber cap 91, the lower end of the suction tube extends into the bottleneck, and the opening on the suction tube seat 93 forms a certain degree of sealing.

Returning to fig. 2, a hole (not shown) is formed through the top wall of the outer cover 3, a portion of the button retaining ring 42 of the button 4 extends upward from the hole, and the button retaining ring 42 is located inside the outer cover 3 and is axially retained by the hole formed in the top wall of the outer cover 3. A spring 5 is also abutted between the lower end face of the button retaining ring 42 and the inner lid top wall 26. An inner gear face 31 is arranged at the corresponding position of the lower part of the inner side wall of the outer cover 3, and the inner gear face 25 is tightly matched with the outer gear face 31 to fixedly assemble the inner cover 2 and the outer cover 3 together. The inside wall bottom of enclosing cover 3 is equipped with the enclosing cover assembly spacing groove 32 of round indent, and the position corresponds with inner cup assembly spacing collar 28, and both axial alignments when supplying inner cup 2 and enclosing cover 3 to assemble.

In the quick-opening straw bottle of the embodiment, when the quick-opening straw bottle is used, a user pinches the outer cover 3 by a thumb and a middle finger of one hand, the forefinger presses the button 4, and the claw inclined plane 411 pushes the inner cover elastic sheet 22 away after the button 4 descends, so that the elastic sheet convex rib 23 is separated from the bottle opening positioning groove 11, and the locking relation between the inner cover 2 and the bottle opening is released; at the same time, pressing the button 4 causes the rubber cap 91 to be compressed. After releasing the index finger, the rubber cap 91 is reset to suck the liquid in the bottle 1 into the straw 92, and the inner cap 2, the outer cap 3, the button 4 and the straw assembly are removed from the bottle as a whole to be used.
