Description

Technical Field

[0001] This utility model relates to the field of packaging bottle technology, specifically to a cosmetic packaging bottle and packaging container. Background Technology

[0002] Cosmetics are commonly used products in daily life, and as living standards improve, people's demand for cosmetics is also increasing. As daily necessities, cosmetics are often carried in bags, and many existing cosmetics, such as face creams and lotions, are dispensed via pump dispensers.

[0003] Specifically, cosmetic packaging bottles are sealed to the bottle body via a pump head assembly, and a long conduit extending to the bottom of the bottle is fixedly connected below the pump head. Its working principle is as follows: when the pump head is pressed, the piston assembly inside the pump head generates negative pressure, drawing the cosmetic liquid from the bottle into the pump head chamber through the long conduit, and then discharging it through the pump head's outlet, thus achieving quantitative dispensing. As consumers increasingly demand portability, simplified structure, and production cost control in cosmetic packaging, the shortcomings of the traditional long-tube pump head structure have become increasingly apparent: the long conduit not only increases the number of components in the packaging bottle, leading to cumbersome assembly processes, but also increases material waste and processing costs during production.

[0004] Therefore, there is an urgent need to develop a cosmetic packaging bottle and container to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cosmetic packaging bottle and container, eliminating the need for the long tubing required in traditional pump-type packaging bottles, simplifying the overall structure of the cosmetic packaging bottle, and reducing the complexity, processing costs, and manufacturing costs of the cosmetic packaging bottle assembly process. The implementation of this technical solution is as follows:

[0006] A cosmetic packaging bottle includes: a bottle body, a male valve assembly, and a cap. The bottle body has a receiving cavity for containing cosmetics and a bottle opening at its top. The male valve assembly is disposed within the bottle opening. By pressing the male valve assembly, a negative pressure is generated inside the bottle body, thereby causing the cosmetics to be squeezed out from the receiving cavity. The cap is disposed on the upper end of the male valve assembly to seal the male valve assembly, and the cap is provided with a valve outlet for inserting a valve stem.

[0007] The male valve assembly includes a valve stem, a valve core, and a valve body. The valve body is located at the bottle opening, the valve core is sleeved within the valve body, a spring is provided between the valve core and the valve body, and the valve stem is inserted into the valve core.

[0008] Preferably, the surface of the valve body is provided with a plurality of liquid inlet holes, which are evenly arranged at equal intervals along the axial direction of the valve body; the liquid inlet holes are used to press the valve stem to allow the liquid inside the bottle to flow into the valve body.

[0009] Preferably, the inner wall of the valve core is provided with a plurality of reinforcing ribs, which are evenly arranged at equal intervals along the axial direction of the valve core. The reinforcing ribs are used to guide the valve stem to move within the valve core, and a gap is formed between the valve core and the valve stem through the reinforcing ribs to allow the cosmetic liquid to flow.

[0010] Preferably, a support beam is provided at the inner bottom of the valve core, the support beam being used to abut against the valve stem to prevent the valve stem from abutting against the inner bottom of the valve core during movement.

[0011] Preferably, the sidewall of the bottle is provided with a plurality of recessed grooves, the direction of which is consistent with the discharge direction of the cosmetic, and the plurality of grooves are evenly distributed at equal intervals along the axial direction of the bottle.

[0012] Preferably, an inner sealing ring is provided between the cover and the valve body.

[0013] Preferably, the cap is made of aluminum.

[0014] This application also relates to a cosmetic packaging container, including an outer bottle and the aforementioned cosmetic packaging bottle, wherein the outer bottle is fitted over the outside of the bottle body and is connected by a connecting ring of the outer ring of the cap.

[0015] Preferably, an outer sealing ring is provided between the outer bottle and the connecting ring of the cap.

[0016] Compared with the prior art, this application has the following advantages:

[0017] This technical solution replaces the long tubing and independent pump body structure required by traditional pump-head packaging bottles with a modular combination of the valve stem, valve core, valve body, and spring of the male valve assembly. The reinforcing ribs on the inner wall of the valve core not only ensure stable guidance of the valve stem and prevent deviation from affecting liquid dispensing, but also form a flow gap with the valve stem. Together with the inner bottom support beam, it prevents the valve stem from blocking the channel. Combined with the liquid inlet of the valve body and the valve stem, it forms a complete air discharge and cosmetic guide channel. Negative pressure can be quickly formed and cosmetics can be dispensed by pressing without the need for a long tubing. This design not only greatly simplifies the overall structure of cosmetic packaging bottles, reduces the number of parts, and reduces the complexity of assembly processes, but also eliminates the processing and adaptation of long tubing, effectively reducing processing and manufacturing costs. At the same time, the compact assembly of the male valve assembly with the bottle body and cap, combined with the sealing effect of the inner sealing ring, ensures the stability of negative pressure dispensing, avoids cosmetic residue and leakage, and balances practicality and user experience.

[0034] Example 1

[0035] Embodiments of this application provide a cosmetic packaging bottle that achieves simplified assembly and reduced costs through a negative pressure liquid dispensing structure without long conduits; such as Figure 1-4 As shown, the device includes a bottle body 1, a male valve assembly 2, and a cap 3. The bottle body 1 has a cavity for containing cosmetics and a bottle opening 11 at its top. The side wall of the bottle body 1 is provided with several recessed grooves 12. The bottle body 1 can be contracted by external force to squeeze out the cosmetics. The male valve assembly 2 is disposed inside the bottle opening 11. By pressing the male valve assembly 2, a negative pressure is generated inside the bottle body 1, thereby squeezing out the cosmetics from the cavity. The cap 3 is disposed on the upper end of the male valve assembly 2 to seal the male valve assembly 2. The cap 3 is provided with a valve outlet 31 for the cosmetics to be squeezed out.

[0036] In this embodiment, initially, the cosmetics are contained within the bottle 1, which is in an expanded state. When the bottle 1 is subjected to negative pressure and contracts, the cosmetics are squeezed out. Specifically, pressing the male valve assembly 2 causes the air inside the bottle 1 to be expelled, thereby creating a pressure difference with the external atmospheric pressure and generating negative pressure. Due to the function of the groove 12, a textured surface is formed on the outside of the bottle 1. After pressing the male valve assembly 2, negative pressure can be quickly generated inside the bottle 1, and the cosmetics inside the bottle 1 can be quickly squeezed out.

[0037] Specifically, the bottle body 1 is made of transparent plastic, allowing the cosmetics inside to be clearly seen. The bottle body 1 and the bottle opening 11 are integrally molded, making assembly more convenient and faster, and improving production efficiency. In addition, the orientation of several grooves 12 is consistent with the discharge direction of the cosmetics. The grooves 12 are evenly spaced along the axis of the bottle body 1. On the one hand, the grooves 12 create a textured surface on the outside of the bottle body 1. When the male valve assembly 2 discharges air from the bottle body 1, the textured surface accelerates the contraction of the bottle body 1, helping to quickly create negative pressure inside the bottle body 1, pushing the cosmetics at the bottom towards the bottle opening 11 without the need for a long tube. On the other hand, the guiding effect of the grooves 12 makes the cosmetics squeeze out more smoothly, reducing residue on the inner wall of the bottle body 1, while optimizing the appearance of the bottle body 1, achieving a unity of function and aesthetics.

[0038] In some implementations, such as Figure 2-4 As shown, the male valve assembly 2 includes a valve stem 21, a valve core 22, and a valve body 24. The valve body 24 is located at the bottle mouth 11. The valve core 22 is sleeved inside the valve body 24. A spring 23 is provided between the valve core 22 and the valve body 24. The spring 23 provides a restoring force for the valve core 22. The valve stem 21 is inserted into the valve core 22.

[0039] In some implementations, such as Figure 6-7 As shown, the inner wall of the valve core 22 is provided with a plurality of reinforcing ribs 221, which are evenly spaced along the axial direction of the valve core 22. The reinforcing ribs 221 guide the valve stem 21 within the valve core 22 and prevent the valve stem 21 from shifting and affecting liquid dispensing. A gap is also formed between the valve core 22 and the valve stem 21 through the reinforcing ribs 221 to allow air or cosmetics to circulate. A support beam 222 is provided at the inner bottom of the valve core 22, which abuts against the bottom end of the valve stem 21 to prevent the valve stem 21 from blocking the flow channel during movement, ensuring smooth discharge of air or cosmetics. The surface of the valve body 24 is provided with a plurality of liquid inlet holes 241, which are evenly spaced along the axial direction of the valve body 24. The liquid inlet holes 241 are used to press the valve stem 21 to allow liquid from inside the bottle 1 to flow into the valve body 24.

[0040] It should be noted that the valve stem 21 is a through-type hollow stem, and the valve core 22 has a cavity for accommodating the valve stem 21 and cosmetics. The upper surface of the cavity has an opening for the valve stem 21 and cosmetics to enter the cavity. When it is necessary to squeeze out liquid, by repeatedly pressing the valve stem 21, the valve stem 21 drives the valve core 22 to move into the bottle body 1, so that the upper surface of the valve core 22 is lower than the top of the liquid inlet hole 241. Air or cosmetics enter the valve core 22 through the liquid inlet hole 241 of the valve body 24. Since the valve core 22 is provided with reinforcing ribs 221 and support beams 222, air or cosmetics flow in the gap between the valve core 22 and the valve stem 21, and finally exit from the valve stem 21, so that negative pressure is generated in the bottle body 1, and finally the cosmetics are squeezed out. The cosmetics can be pushed from the accommodating cavity to the valve stem 21 by using pressure difference without the need for a long tube.

[0041] In some implementations, such as Figure 5 As shown, an inner sealing ring 32 is provided between the cap 3 and the valve body 24. By providing the inner sealing ring 32, the infiltration of external air is prevented from affecting the negative pressure formation effect, while preventing cosmetic leakage and ensuring the stability of negative pressure liquid output.

[0042] Furthermore, the cover 3 is made of aluminum.

[0043] Example 2

[0044] like Figure 5 As shown, this embodiment discloses a cosmetic packaging container, including an outer bottle 4 and the cosmetic packaging bottle in Embodiment 1. The outer bottle 4 is fitted over the bottle body 1 and connected by a connecting ring on the outer ring of the cap 3. An outer sealing ring 33 is provided between the outer bottle 4 and the connecting ring of the cap 3 to improve the sealing performance between the outer bottle 4 and the bottle body 1. Specifically, the outer bottle 4 can be a rigid bottle such as a transparent glass bottle, providing stable support. Before use, gas is injected between the outer bottle 4 and the bottle body 1. In actual use, the bottle body 1 acts as an airbag-type bottle body 1. When the valve assembly 2 is pressed, the air inside the bottle body 1 is expelled, causing the pressure to decrease, while the pressure between the outer bottle 4 and the bottle body 1 remains unchanged, creating a pressure difference that squeezes the bottle body 1 to expel the cosmetic.

[0045] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
