DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in this application are only a part of the embodiments of the present application, rather than all the embodiments.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0035] Embodiment 1: As shown in Figures 1-3, a press-type pump head includes a press member 10, an inner cover assembly, a pump assembly 40 and a suction pipe 50. The inner cover assembly includes an inner cover 20 and an inner ring 30 fixedly installed in the inner cover 20. The inner cover 20 and the inner ring 30 can be fixed by snapping, gluing, plugging, etc. A nozzle 12 is provided on the press member 10. The press member 10 is axially movable and circumferentially fixedly installed in the inner ring 30. The pump assembly 40 is fixedly installed in the inner ring 30. The press member 10 is installed in the pump assembly 40. The first end of the suction pipe 50 is fixedly installed in the pump assembly 40. The second end of the suction pipe 50 is a free end, and the second end of the suction pipe 50 is provided with a suction nozzle 51. The nozzle 12 and the suction nozzle 51 are located on the same side of the pump head.

[0036] As shown in Figures 1-5, the so-called pressing member 10 is axially movable and circumferentially fixedly installed in the inner ring 30 means that the pressing member 10 can run axially along the inner ring 30, but cannot rotate circumferentially relative to the inner ring 30, that is, when the inner cover assembly rotates, the inner cover assembly can drive the pressing member to rotate at the same time, and similarly, when the pressing member rotates, it can also drive the inner cover assembly to rotate at the same time; the so-called nozzle 12 and the suction nozzle 51 are arranged toward the same side of the pump head, which means: the section passing through the central axis of the inner cover assembly is defined as a longitudinal section, assuming that there is a first longitudinal section and a second longitudinal section, the first longitudinal section passes through the nozzle 12, and the second longitudinal section is perpendicular to the first longitudinal section, and the second longitudinal section divides the pump head into two parts, namely the first side and the second side of the pump head, then the nozzle 12 and the suction nozzle 51 are both located on the first side of the pump head; or, the nozzle 12 and the suction nozzle 51 are both located on the second side of the pump head.

[0037] During assembly, the pump assembly 40 is installed in the inner ring 30 of the inner cover assembly, the pressing piece 10 is installed in the inner ring 30 of the inner cover assembly, and the lower end of the pressing piece 10 is inserted into the pump assembly 40 to ensure that pressing down the pressing piece 10 can start the pump assembly 40. Because the pressing member 10 is installed in the inner cover assembly in a circumferentially non-rotatable manner, the position of the nozzle 12 of the pressing member 10 is fixed relative to the inner cover assembly. The straw 50 is then fixedly installed on the pump assembly 40, and it is ensured that the suction nozzle 51 of the suction nozzle 50 is on the same side as the nozzle 12 of the pressing member 10. Therefore, during use, the nozzle 12 of the pressing member and the suction nozzle 51 of the suction nozzle 50 are always on the same side of the pump head. When in use, the pump head is installed in the bottle assembly. When the user lifts the pump head and tilts the pump head to align the nozzle 12 with the user, the bottom of the bottle assembly on the same side as the nozzle is at a low position, and the suction nozzle 51 of the suction nozzle 50 is also at a low bottom of the bottle. Therefore, the suction nozzle 51 can suck the material in the bottle assembly clean, reducing waste of resources. In traditional pump heads, since the pressing part can rotate relative to the inner cover assembly, the position of the nozzle on the pressing part and the position of the suction nozzle of the straw are random, and there is no guarantee that the nozzle and the suction nozzle are on the same side of the pump head. When the nozzle and the suction nozzle are on different sides of the pump head, when there is still a small amount of material in the bottle assembly, that is, the material height is lower than the suction nozzle position, the suction nozzle cannot suck out the material, so some material remains in the bottle assembly, resulting in a waste of resources. For high-value-added cosmetic materials, it also greatly increases the user's usage cost.

[0038] The inner cap assembly is detachably mounted on the bottle assembly, and the bottle assembly includes a bottle bottom. The center point of the bottle bottom is defined as point A, the center point of the orthographic projection of the nozzle 12 on the bottle bottom is defined as point B, and the center point of the orthographic projection of the suction nozzle 51 on the bottle bottom is defined as point C. Then, the angle between the straight line AB and the straight line AC is ≤90°. Optionally, the angle between the straight line AB and the straight line AC is ≤30°. Optionally, the straight line AB and the straight line AC overlap with each other, that is, the nozzle 12 and the suction nozzle 51 are arranged in the same radial direction of the bottle assembly. This ensures that when in use, the suction nozzle 51 of the straw 50 is located at the lowest point of the bottle bottom, ensuring that the cosmetic material in the bottle assembly can be used up, that is, no cosmetic material remains, thereby reducing the user's usage cost and reducing resource waste.

[0039] Optionally, a limit assembly is provided between the pressing member 10 and the inner ring 30, and the pressing member 10 is installed in the inner ring 30 axially movable and circumferentially fixed through the limit assembly. The limit assembly includes a first sub-limit assembly and a second sub-limit assembly. The first sub-limit assembly is provided in the pressing member 10, and the second sub-limit assembly is provided in the inner ring 30.

[0040] As shown in Figures 1 and 4, a discharge tube 11 is provided within the pressing member 10, which is connected to the nozzle 12. A first sub-limiting assembly is provided on the inner sidewall of the pressing member 10, and the discharge tube 11 is inserted into the pump assembly 40. During use, the pressing member 10 drives the pump assembly 40 downward under the action of an external force. When the external force disappears, the pressing member 10 returns to its original position under the action of a spring within the pump assembly 40. Simultaneously, the pump assembly 40 draws cosmetic material from the bottle assembly, which is then sprayed out through the discharge tube 11 and nozzle 12 for the user to use. Designing the first sub-limiting assembly on the inner sidewall of the pressing member 10, compared to conventional pressing members with a limiter provided on the outer sidewall, allows the first sub-limiting assembly to be concealed within the pressing member 10, whether the pressing member 10 is in its natural state or in a pressed state. This avoids the risk of the first sub-limiting assembly being exposed, affecting the overall aesthetics of the pump head, and preventing it from being damaged by bumps.

[0041] As shown in Figure 5, the inner ring 30 includes a first barrel 31, which extends radially inward to form a boss 32. The boss 32 extends axially upward to form a second barrel 34. A second sub-limiting assembly is provided on the second barrel 34. An internal thread 33 is provided on the inner sidewall of the first barrel 31 below the boss 32. The boss 32 is located in the middle of the first barrel 31 in the axial direction. A gap is provided between the first barrel 31 and the second barrel 34. The pressing member 10 is inserted into the gap, and the first sub-limiting assembly is engaged with the second sub-limiting assembly. The internal thread 33 on the inner ring 30 is used to screw the bottle assembly.

[0042] The inner sidewall of the pressing member 10 is provided with N first sub-limiting assemblies, and the second cylindrical body 34 is provided with N second sub-limiting assemblies. The first sub-limiting assemblies correspond to the second sub-limiting assemblies one-to-one, where N ≥ 2 and N is an integer. The distance between two adjacent first sub-limiting assemblies can be equal or unequal.

[0043] Optionally, the inner wall of the pressing member 10 is provided with three first sub-limiting components, which are respectively defined as the first sub-limiting component A, the first sub-limiting component B and the first sub-limiting component C. The first sub-limiting component B and the nozzle 12 are located on the same longitudinal section of the pressing member 10, wherein the longitudinal section passes through the central axis of the pressing member 10, that is, the first sub-limiting component B and the nozzle 12 are in the same radial position of the pressing member 10. In this way, during assembly, the position of the limiting component can be judged according to the position of the nozzle 12, so that the pressing member 10 can be quickly installed into the inner cover assembly. As shown in Figure 9, the angle between the first sub-limiting component A and the first sub-limiting component B is α, the angle between the first sub-limiting component C and the first sub-limiting component B is β, and the angle between the first sub-limiting component A and the first sub-limiting component C is γ, wherein α=β, γ≤α. That is, the first sub-limiting assembly A and the first sub-limiting assembly C are symmetrically arranged relative to the nozzle 12. In one possible embodiment, the angle between the first sub-limiting assembly A and the first sub-limiting assembly B is 135°, the angle between the first sub-limiting assembly C and the first sub-limiting assembly B is 135°, and the angle between the first sub-limiting assembly A and the first sub-limiting assembly C is 90°. As shown in FIG4 , the first sub-limiting assembly B and the nozzle 12 are in the same radial direction as the pressing member 10. In the figure, the first sub-limiting assembly is a rib 13, which facilitates rapid positioning during assembly of the pressing member 10. After all the first sub-limiting assemblies are engaged with all the second sub-limiting assemblies one by one, the pressing member 10 is fully assembled. The symmetrical arrangement of the first sub-limiting assembly A and the first sub-limiting assembly C along the nozzle 12 can improve the operational stability of the pressing member 10.

[0044] In a first possible embodiment, the first sub-stop assembly includes a first protrusion, and the second sub-stop assembly includes a second protrusion. The first protrusion is axially provided on the inner sidewall of the pressing member 10, and the second protrusion is axially provided on the inner ring 30. When the pressing member 10 is installed in the inner cover assembly, the first and second protrusions engage with each other. The inner sidewall of the pressing member 10 is axially provided with a plurality of first protrusions in the shape of strips, and the outer sidewall of the inner cover assembly is axially provided with a plurality of second protrusions in the shape of strips.

[0046] In a third possible embodiment, a retaining groove is provided axially on the inner sidewall of the pressing member 10, and a retaining rib is provided axially on the inner ring 30. The pressing member 10 has a plurality of strip-shaped retaining grooves axially provided on the inner sidewall, and the inner ring 30 has a plurality of strip-shaped retaining ribs axially provided on the outer sidewall. The retaining grooves and retaining ribs are engaged in a one-to-one correspondence.

[0047] In a fourth possible embodiment, as shown in Figures 4 and 5, the first sub-limiting assembly includes a rib 13 or a notch 35, and the second sub-limiting assembly includes a notch 35 or a rib 13. When the pressing member 10 is installed on the inner cover assembly, the rib 13 is inserted into the notch 35. The inner side wall of the pressing member 10 is provided with a rib 13 along the axial direction, and the inner ring 30 is provided with a notch 35 along the axial direction. In this embodiment, the inner side wall of the pressing member 10 is provided with three ribs 13, which are defined as the first rib, the second rib and the third rib respectively. The second rib is in the same radial position as the nozzle, the angle between the first rib and the second rib is 135°, the angle between the third rib and the second rib is 135°, and the angle between the first rib and the third rib is 90°. Correspondingly, three notches 35 are provided on the second cylinder 34. The notches 35 are opened along the axial direction of the second cylinder 34. During assembly, the ribs are inserted into the notches.

[0048] In a fifth possible embodiment, the inner sidewall of the pressing member 10 is provided with an axial notch 35, and the inner ring 30 is provided with an axial rib 13. The inner sidewall of the pressing member 10 is provided with a plurality of axially shaped notches 35, and the inner ring 30 is provided with a plurality of axially shaped ribs 13. The ribs 13 engage with the notches 35 in a one-to-one correspondence.

[0049] As shown in FIG. 1 , the straw 50 is an integrally formed part and is curved; the second end of the straw 50 is inclined toward the nozzle.

[0050] Example 2: As shown in FIG6 , the structure of the suction pipe 50 in this embodiment differs from that of the suction pipe 50 in Example 1. The suction pipe 50 includes a first sub-suction pipe 52 and a second sub-suction pipe 53. The first end of the first sub-suction pipe 52 is fixedly connected to the pump assembly 40, and the second end of the first sub-suction pipe 52 is fixedly mounted to the first end of the second sub-suction pipe 53. The second end of the second sub-suction pipe 53 is free, and the second end of the second sub-suction pipe 53 is provided with a suction nozzle 51. The first sub-suction pipe 52 and the second sub-suction pipe 53 are arranged non-coaxially. Alternatively, the first sub-suction pipe 52 is arranged coaxially with the pump assembly 40, and the second sub-suction pipe 53 is arranged obliquely to the first sub-suction pipe 52, with the second end of the second sub-suction pipe 53 tilted toward the nozzle 12.

[0051] As shown in Figures 7-11, a cosmetic container includes a pump head, a bottle assembly, and an outer cap 80. The inner cap assembly is detachably mounted on the bottle assembly, the straw 50 is positioned within the bottle assembly, and the outer cap 80 is sleeved within the inner cap assembly. The bottle assembly includes an outer bottle 70 and an inner bottle 60 positioned within the outer bottle 70. The outer bottle 70 is formed in one step by blow molding, and the inner bottle 60 is blow molded directly within the outer bottle 70. The pump head of Example 1 used in this embodiment has an inner ring 30 in the inner cap assembly and an inner bottle 60 in the bottle assembly that are detachably assembled together by means of screw connection, snap-fit, interference fit, or the like. The bottle assembly is used to hold cosmetic materials, and the suction nozzle 51 of the straw 50 abuts against the edge of the bottle assembly. In one possible embodiment, the inner ring 30 is provided with an internal thread 33, and the inner bottle 60 is provided with an external thread. The pump head and bottle assembly are detachably assembled together by means of the internal and external threads. The inner bottle 60 and the outer bottle 70 are both made by a blow molding process, so that the inner bottle 60 and the outer bottle 70 can have a large thickness.

[0052] During production, the outer bottle 70 is blow-molded first, and then the inner bottle 60 is blow-molded directly into the outer bottle 70. Therefore, the two are tightly combined and no additional assembly steps are required, simplifying the assembly process. During use, when a user generally has a small amount of cosmetic material left in the bottle assembly or needs to spray the face, the user tilts the cosmetic container so that the nozzle 12 is aimed at the user, and activates the pump assembly 40 by pressing the pressing member 10 to spray the cosmetic material in the bottle assembly through the nozzle 12. In view of the above-mentioned usage habits of the user, the present application always keeps the arrangement direction of the suction nozzle 51 of the straw consistent with the nozzle 12 of the pressing member 10. Therefore, when the cosmetic container is tilted and the nozzle is aimed at the user, the suction nozzle 51 of the straw is always located at the lowest point of the bottle assembly, so that the cosmetic material in the bottle assembly can be completely used up.

[0053] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
