Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging materials, in particular to a packaging bottle for emulsion and a pressure pump thereof. Background Art

[0002] A cosmetic bottle is divided into two parts, with two independent chambers for different cosmetics. This is a common cosmetic bottle design. Separate bottle packaging can ensure the storage effect of different ingredients and avoid the loss of sensitive ingredients. For this type of packaging, the pumps used on the market are either double-tube pumps that share one pump, so that two cosmetics can be pumped out of one pump at the same time, or double-head pumps. The use mode of double-head pumps is more flexible, allowing users to freely choose to use two cosmetics together or use one cosmetic alone. Most manufacturers design double-head pumps that are integrated together, which is not convenient to replace. Some double-head pumps are designed as independent pumps. Although they can be replaced in the conventional threaded manner, it is troublesome to replace them twice. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0032] like Figure 1-7 As shown, a double-head pressure pump comprises a detachable mounting cap assembly 1 and two sets of pump assemblies 2;

[0033] The two sets of pump assemblies 2 include two pressure pump head assemblies 21 and two pressure pump action assemblies 22 respectively installed under the two pressure pump head assemblies 21;

[0034] The detachable mounting cap assembly 1 includes a cover assembly 11 and a nut 12, the cover assembly 11 is provided with a mounting hole for mounting the pressure pump head assembly 21, the top of the nut 12 is provided with a hollow position 121 for the pressure pump head assembly 21 to pass through and a clamping portion 122 located around the hollow position 121, the inner side wall of the nut 12 is provided with an internal thread 123 threadedly connected to the lotion bottle mouth 32, and the cover assembly 11 is installed between the lotion bottle mouth 32 and the clamping portion 122.

[0035] The cover plate assembly 11 includes a cover plate 111 and a sealing gasket 112 located under the cover plate 111 .

[0036] A stopper 124 matching the cover assembly 11 is also provided on the inner side of the nut 12 .

[0037] The outer side of the nut 12 is also connected to two adjusting members 13 that can be raised and lowered on the outer side of the nut 12;

[0038] The two adjusting members 13 correspond to two pump head assemblies 21 respectively. The cross-sections of the two adjusting members 13 are arc-shaped, and the arc thereof matches the nut 12. The sum of the arc lengths of the two adjusting members 13 is smaller than the circumference of the nut 12, and the two adjusting members 13 do not contact each other.

[0039] The outer side of the nut 12 is provided with a plurality of adjustment rails.

[0040] Each set of adjustment rails is provided with a plurality of gears 125 of different heights, and the inlet and outlet of the upper part of each gear 125 are connected to a horizontal rail 126, and the inlet and outlet of each horizontal rail 126 are connected to the same vertical rail 127;

[0041] The lower part of the inner wall of the adjusting member 13 is provided with a positioning portion 131 which slides on the gear position 125 , the horizontal track 126 and the vertical track 127 .

[0042] When the positioning portion 131 is at the highest position 125, the top of the adjusting member 13 abuts against the bottom of the pump head assembly 21; when the positioning portion 131 is at the lowest position 125, the top of the adjusting member 13 is flush with the top of the nut 13;

[0043] The inlet and outlet of the vertical track 127 extend to the top of the adjusting member 13 .

[0044] The pressure pump head assembly 21 includes a pressure pump head housing 211, an arc-shaped liquid outlet pipe 212 and an elastic liquid outlet part 213. The arc-shaped liquid outlet pipe 212 and the elastic liquid outlet part 213 are installed in the pressure pump head housing 211. The lower end of the arc-shaped liquid outlet pipe 212 is connected to the liquid outlet of the pressure pump action assembly 22, and the liquid inlet end of the elastic liquid outlet part 213 is connected to the upper end of the arc-shaped liquid outlet pipe 212.

[0045] The liquid outlet of the elastic liquid outlet member 213 is provided with a plurality of elastic petals 2131 along the circumferential direction; when no liquid is discharged, the plurality of elastic petals 2131 are closed toward the center of the liquid outlet to close the liquid outlet; when liquid is discharged, the plurality of elastic petals 2131 are opened to the surroundings to ensure that the liquid outlet has a sufficient opening degree for smooth liquid discharge.

[0046] The present invention also provides a lotion bottle 3 using the double-head pressure pump, wherein a partition 31 is provided in the lotion bottle 3, and the top of the partition 31 extends to be flush with the lotion bottle mouth 32, dividing the lotion bottle 3 into two independent chambers, and the two pressure pump action components 22 are respectively located in the two independent chambers.

[0047] The outer wall of the lotion bottle mouth 32 is provided with an outer thread 321 matching the inner thread 123 of the nut 12 .

[0048] When the present invention is used, the height of the adjusting member 13 can be adjusted according to the needs of use. If the amount to be discharged at one time is not too much, the adjusting member 13 can be slightly lifted upward to make the positioning portion 131 slide from the lowest gear position 125 to its inlet and outlet, and then the adjusting member 13 can be rotated to make the positioning portion 131 slide into the vertical track 127 along the horizontal track 126, and the adjusting member 13 can be lifted upward to the required horizontal track 126, slid into the horizontal track 136 and then slid to the inlet and outlet of the corresponding gear position 125, and the adjusting member 13 can be slightly pressed downward to make the positioning portion 131 enter the required gear position 125. There is no need to deliberately control the force each time the pump head is pressed. A simple press can discharge liquid according to the liquid discharge amount set by the adjusting member 13, avoiding waste caused by pressing too much at one time. Those skilled in the art can design the height of each gear position 125 according to different liquid discharge amounts.

[0049] When the pump head assembly 21 is pressed, the pump action assembly 22 pumps out the cosmetics in the bottle, and the cosmetics enter the arc-shaped liquid outlet tube 212 and the elastic liquid outlet member 213. The multiple elastic flaps in the closed state are opened by the impact of the cosmetics. When no liquid is discharged, the multiple elastic flaps are reset to seal the elastic liquid outlet member.

[0050] When the cosmetics are taken out of the house, the adjusting member 13 can be adjusted to the highest gear position 125, and the adjusting member 13 can press against the bottom of the pump head assembly 21 to prevent the liquid from being accidentally discharged. When the cosmetics in the bottle are used up, the pump assembly 2 can be replaced with another bottle for use. It is not necessary to configure a pump assembly 2 for each bottle of product, which saves costs and resources and supports environmental protection.

[0051] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
