An air pump, when the press cover is squeezed and moved downward, the air pump will inflate the space between the upper end of the piston in the bottle body and the lower end surface of the rear cover to push the piston to slide downward, so that the liquid in the bottle will flow out from the outlet. When the liquid head flows out, under the action of the spring, when the pressing cap moves upward, a partial Vacuum, under atmospheric pressure, air flows into the first cylinder part or the second cylinder part from the air vent until the cover is pressed and reset.

According to different skin care products, the manufacturer can install the rubber ring in different positions to achieve different extrusion volumes, which can simplify the skin care product packaging bottles of different specifications, and only need to change the position of the rubber ring once. Pressing the amount of skin care products extruded can reduce the use of molds for packaging bottles and changes in factory filling production technology, which is convenient for manufacturers to reduce production costs and improve work efficiency.

In daily use, the user can fine-tune the liquid output of the present invention. The user can drive the rotating adjustment sleeve to rotate by twisting the convex teeth, and at the same time observe the cooperation between the fixed indicator part and the movable indicator part, so that the position of the pressing cover can be changed. The sliding stroke in the back cover changes the amount of skin care products flowing out of the bottle. When the limit protrusion is engaged at the highest point of the limit slope groove, the pressing cover cannot slide down, and at the same time, the movable indicator points to a fixed position. The tail of the indicating part reminds the user that the present invention has been locked, and the skin care products in the bottle will not overflow accidentally.

According to Fig. 1 to Fig. 9, a skin care product packaging bottle described in this embodiment includes a hard bottle body 1, a piston part 2 slidably connected in the bottle body 1, and a rear end fixedly connected to the upper end of the bottle body 1. Cover 4, a rotary adjustment sleeve 6 installed on the inner periphery of the upper end of the rear cover 4 and rotatably connected with the rear cover 4, a pressing cover 5 installed on the upper end of the rear cover and located at the inner circumference of the rotating adjustment sleeve, and a seal installed in the middle of the upper end of the pressing cover 5 The cap 7, the liquid outlet head 8 fixedly connected to the lower end of the bottle body, and the bottle cap 3 threadedly connected to the lower end of the bottle body.

The upper end of the back cover 4 is formed with a back cover 41; the back cover 4 is fixedly connected with the upper end of the bottle body 1 through the back cover 41; the lower end of the back cover 41 is formed with a first tube portion 44 The lower end of the first cylindrical portion 44 is formed with a second cylindrical portion 45; the lower end of the second cylindrical portion 45 is formed with a first vent hole 451; the lower end of the second cylindrical portion 45 is interference-connected with a first one-way valve sheet 40; the first one-way valve sheet 40 completely blocks the first vent hole 451; the space where the lower end of the rear cover 41 is located on the outer periphery of the first cylindrical portion 44 is uniformly formed with two or more holes along the circumferential direction. Limit rod groove 43;

The back cover is plugged into the bottle body, the lower end of the second tube part of the lower part of the back cover is provided with a first vent hole and the lower end of the second tube part is connected with a first one-way valve plate, so the first The one-way valve plate and the second cylinder part form a one-way valve leading from the second cylinder part to the inside of the bottle body.

The pressing cover 5 is slidingly connected with the rear cover 4; the upper end of the pressing cover 5 is formed with a pressing upper end cover 51; the lower end of the pressing upper end cover 51 is formed with a first piston part 55; the outer wall of the first piston part 55 The upper part is formed with a vent 54; the lower end of the first piston part 55 is formed with a second piston part 56; the lower end of the second piston part 56 is formed with a second vent hole 561, and the lower end of the second piston part 56 is connected with interference There is a second one-way valve plate 50; the second one-way valve plate 50 completely blocks the second vent hole 561; the lower part of the outer wall of the first piston part 55 or the lower part of the outer wall of the second piston part 56 is equipped with a rubber ring 57 ;

The second vent hole and the second one-way valve plate form a one-way valve leading from the second piston part to the direction of the rear cover. When the lower part of the outer wall of the first piston part is sleeved with a rubber ring, the first piston part A pump structure is formed with the first cylinder part, so that when the pressing cap is pressed down, the air in the first piston part and the first cylinder part is pressed into the bottle at the upper end of the piston, thereby pushing the piston down to make a certain amount of air in the bottle When the cosmetics flow out, when the rubber ring is sleeved on the lower part of the outer wall of the second piston part, the second piston part and the second cylinder part form an air pump structure, and the air in the second piston part and the second cylinder part is pressed into the bottle body at the upper end of the piston , thus pushing the piston down to make a certain amount of cosmetics in the bottle flow out. The transverse cross-sectional area of the first piston part is 1.5-2 times the transverse cross-sectional area of the second piston part. Depending on the position, the liquid output will be different.

The lower end of the pressing upper end cover 51 is located at the space of the outer periphery of the first piston part 55 and is evenly formed with limit rods 53 equal in number to the limit rod grooves 43 along the circumferential direction; the limit rods 53 and the limit rods The groove 43 is slidingly connected; a spring 9 for resetting the pressing cover is installed between the upper end of the first cylinder part 44 and the lower end of the pressing upper end cover 51; the outer periphery of the upper end of the rotating adjusting sleeve 6 is formed with an adjusting sleeve outer edge 61; The outer wall of the rotation adjustment sleeve is formed with a positioning chuck 62 along the circumferential direction; the side wall of the rear cover is formed with a limit groove 42 that limits the rotation range of the positioning chuck; the side wall of the rotation adjustment sleeve is formed along the circumferential direction. Positioning slope groove 63; said pressing upper end cover is uniformly formed in the peripheral direction with a number of limiting protrusions 52 equal to the limiting slope groove; There is an installation opening 631 for facilitating the installation of the limiting protrusion into the limiting slope groove.

When the pressing cover moves down, the spring is squeezed, and when the downward force on the pressing cover disappears, the spring moves the pressing cover upwards, so that the pressing cover is reset to facilitate the next pressing. The positioning chuck is limited in the limiting groove, and as shown in Figure 4 to Figure 8, when the limiting rod is inserted into the limiting groove, the circumferential movement of the pressing cover is restricted, It can only slide up and down relative to the rear cover. When the positioning chuck is located at the rightmost end of the limit slot in Figure 5, the limit protrusion in Figure 5 is located at the highest point of the slope groove. At this time, the limit protrusion is locked on the At the highest point of the limit groove, when the rotating adjustment sleeve is turned clockwise, the stroke of the limit protrusion in the height direction in the limit groove becomes larger and larger until the limit protrusion moves to the top of the installation port. At this time, the positioning The chuck is limited to the far left of the limit slot in Figure 5. In order to limit the rotation of the rotating adjusting sleeve when the pressing cover is moved down, the slope of the slope groove is not more than 20 degrees.
