Description

Technical Field

[0001] The utility model relates to a liquid cosmetic packaging container, in particular to a press-type straw bottle. Background Art

[0002] The push-type straw bottle is also called a non-vacuum bottle. The working principle is to set a pump core assembly connected to the liquid in the bottle body, control the pump core to move up and down to squeeze the gas space in the pump core assembly, so that negative pressure is generated in the gas space, and the liquid in the bottle body is sucked into the gas space by the straw; the gas space is squeezed again, and the liquid is discharged from the liquid outlet of the non-vacuum bottle. Conventional push-type straw bottles are all direct-pressed, with the pressing part connected to the top of the pump core assembly, and the pressing part is pressed along the axis of the pump core to drive the pump core to move up and down to complete the suction process. However, the up and down pressing of fingers does not conform to the joint setting of the human body, which results in a poor experience for users when pressing the pump core. Utility Model Content

[0032] like Figure 1 to Figure 2 The push-type straw bottle shown includes a bottle body 3 for loading liquid cosmetics, a shoulder sleeve 1 installed on the upper opening of the bottle body 3, a cover body 2 covering the upper opening of the shoulder sleeve 1, and a pump core assembly 5 having an upper opening 51 and a lower opening 52; the principle of the pump core assembly 5 is the existing technology, by compressing the gas space 58 in the pump core assembly 5, the liquid is sucked from the lower opening 52 to the upper opening 51, and a liquid flow channel 57 is formed between the upper opening 51 and the lower opening 52.

[0033] Specifically, Figure 6 and Figure 7As shown, the pump core assembly 5 includes a straw 53 extending into the bottle body 3, a pump housing 54 connected to the end of the straw 53, and a pump core 55 disposed in the pump housing 54; the other end of the straw 53 is the lower opening 52 of the pump core assembly 5, and the upper part of the pump core 55 is the upper opening 51 of the pump core assembly 5. A one-way valve 59 is disposed at the connection between the pump housing 54 and the straw 53; the pump housing 54 is located in the shoulder sleeve 1, and the pump core 55 can move relatively downward along the side wall of the pump housing 54 driven by the pressing force, and the bottom of the pump core 55 squeezes the gas space 58 of the pump housing 54. A spring 56 arranged radially is connected between the pump core 55 and the pump housing 54. The spring 56 has a damping force that prevents the nozzle portion 4 from moving from the normal position to the compressed position, and provides the nozzle portion 4 with an upward reset ability after the pressing force disappears. The air pressure change in the pump housing 54 will produce an air pump effect, and the liquid will flow into the pump housing 54 from the lower opening 52 of the straw 53; the pump core 55 is squeezed downward again, and the liquid in the pump housing 54 will move along the liquid flow channel 57 to the upper opening 51.

[0034] Furthermore, the pump housing 54 is clamped between the bottle body 3 and the shoulder sleeve 1 , and a sealing ring 6 is provided at the connection between the pump housing 54 and the bottle body 3 to prevent liquid leakage.

[0035] like Figure 5 As shown, a nozzle portion 4 is further provided in the shoulder sleeve 1, one end of the nozzle portion 4 is connected to the upper opening 51 of the pump core assembly 5 and communicates with the liquid flow channel 57, and the other end of the nozzle portion 4 extends out of the shoulder sleeve 1 and has a liquid outlet 41 for liquid to flow out. The shoulder sleeve 1 is provided with a normal position and a compression position with an upper and lower position relationship. When no pressing force is applied, the nozzle portion 4 is located at Figure 8 When the pressing force is applied, the nozzle portion 4 moves up and down relative to the shoulder sleeve 1 from the normal position to Fig. 9 In the compression position shown, the pump core 55 of the pump core assembly 5 compresses the gas space 58 in the pump housing 54 .

[0036] like Figure 4 As shown, the rear end of the cover body 2 has a rotation center relative to the shoulder sleeve 1, and the front end of the cover body 2 has a pressing portion 21 that abuts against the nozzle portion 4 when the cover body 2 rotates, and the pressing portion 21 provides pressing force to the nozzle portion 4 when abutting against the nozzle portion 4.

[0037] like Figure 3 As shown, two groups of columns 11 are arranged side by side in the shoulder sleeve 1 and a fixed shaft 12 is arranged between the upper ends of the two groups of columns 11, and a rotating shaft buckle 22 which is clamped to the fixed shaft 12 is arranged at the rear end of the cover body 2 corresponding to the position of the fixed shaft 12; the central axis of the fixed shaft 12 forms the rotation center of the above-mentioned cover body 2.

[0038] In this embodiment, the pressing portion 21 is two pressing blocks arranged on the lower end surface of the cover body 2, and two pressure-bearing portions 42 are arranged at positions corresponding to the pressing blocks on the nozzle portion 4, and the pressing blocks abut against the pressure-bearing portions 42 when rotating. The pressure-bearing portion 42 is a cylindrical structure, and the pressing blocks will continuously contact the arc surface of the pressure-bearing portion 42 during the pressing process, thereby reducing the pressing pressure on the cover body 2.

[0039] Furthermore, the cover body 2 is provided with pressing lines 23 on the upper end surface corresponding to the pressing portion 21 to indicate the location pressed by the user. A pattern may also be designed or a product logo may be provided on the upper end of the cover body 2 according to customer needs.

[0040] Furthermore, an annular limiting groove 13 is provided on the end surface opposite to the cover body 2, and the limiting groove 13 has an inclined limiting surface 14. When the cover body 2 drives the nozzle part 4 to move to the compression position, the peripheral lower edge of the cover body 2 abuts against the inclined limiting surface 14, thereby limiting the position of the nozzle part 4 in the compression position.

[0041] Furthermore, a first clamping edge 15 is provided on the side opposite to the shoulder sleeve 1 and the cover body 2, and a second clamping edge 24 is provided on the cover body 2 at a position corresponding to the first clamping edge 15. When the nozzle portion 4 is in a normal position, the second clamping edge 24 is engaged with the lower end of the first clamping edge 15, thereby stabilizing the relative positions of the shoulder sleeve 1 and the cover body 2.

[0042] The working process in this embodiment is as follows: hold the bottle body 3 of the straw bottle, press the pressing pattern 23 of the cover body 2 with the index finger, and apply pressing force to the cover body 2; the rear end of the cover body 2 rotates around the fixed axis 12, and the front end of the cover body 2 applies downward pressure to the nozzle part 4, driving the nozzle part 4 to move to the compression position, so that the pump core 55 compresses the spring 56 relative to the pump housing 54, and the gas in the pump housing 54 is discharged from the liquid flow channel 57; after the pressing force is removed, the spring 56 returns to its normal position, driving the nozzle part 4 to move to the normal position, and negative pressure is generated in the pump housing 54, and the liquid is transferred from the bottle body 3 to the pump housing 54 through the straw 53 through the one-way valve 59; press the cover body 2 again, and the liquid in the pump housing 54 is squeezed and flows out from the upper opening 51 of the pump core 55 along the liquid flow channel 57.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
