Description

Technical Field

[0001] This utility model belongs to the field of cosmetics technology, specifically relating to a double-ended dropper bottle structure. Background Technology

[0002] With the popularization of cosmetic knowledge and the aggravation of environmental pollution, people's requirements for cosmetics are also getting higher and higher. Many women try to avoid products containing preservatives when choosing products. Therefore, dropper bottles, which are used to hold small amounts of liquid cosmetics and skin care products, have emerged and become an important form of cosmetic packaging. The existence of dropper bottles allows women to carry a certain amount of cosmetics or skin care products when traveling for business or leisure.

[0003] Traditional dropper bottles have only one storage space inside, meaning that a single dropper bottle can only carry one type of liquid. If you want to carry different liquids, you need to carry different dropper bottles, which results in multiple dropper bottles taking up a lot of space and making them inconvenient to carry. Utility Model Content

[0004] The purpose of this invention is to provide a double-ended dropper bottle structure that can carry two different cosmetic and skincare liquids within a certain space, reducing the space required when carrying different cosmetic and skincare liquids, making it easier to carry multiple cosmetic and skincare liquids, and reducing the difficulty of carrying them.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-4 As shown, a double-ended dropper bottle structure includes a connecting sleeve 1. An upper inner bottle 2 and a lower inner bottle 5 are disposed inside the connecting sleeve 1, symmetrically arranged with their opposite ends extending to the outside of the connecting sleeve 1. An upper dropper 3 is disposed inside the upper inner bottle 2, with one end extending to the outside of the upper inner bottle 2. A fourth sealing cap 9 is disposed on the outer wall of the upper dropper 3, and the upper dropper 3 is fixed to the upper inner bottle 2 by the fourth sealing cap 9. A lower dropper 6 is disposed inside the lower inner bottle 5, with one end extending to the outside of the lower inner bottle 5. A second sealing cap 7 is disposed on the outer wall of the lower dropper 6, and the lower dropper 6 is fixed to the lower inner bottle 5 by the fourth sealing cap 9. The connecting sleeve... The top of the connecting sleeve 1 is fitted with a first sealing cap 4, and the bottom of the connecting sleeve 1 is fitted with a third sealing cap 8. The outer wall of the upper inner bottle 2 is provided with a first retaining ring 14, and the outer wall of the lower inner bottle 5 is provided with a second retaining ring 15. The diameters of the first retaining ring 14 and the second retaining ring 15 are both larger than the outer diameter of the connecting sleeve 1. Since the connecting sleeve 1 is provided with two inner bottles, the upper inner bottle 2 and the lower inner bottle 5, for holding different liquids, different cosmetic liquids can be carried through one dropper bottle structure during business trips and travels. It is possible to carry two different cosmetic liquids in a certain space, reducing the space required when carrying different cosmetic liquids, making it more convenient to carry multiple cosmetic liquids, and reducing the difficulty of carrying them.

[0026] See attached document Figure 3The upper dropper 3 has multiple first protrusions 10 on the top of its outer wall, and the lower dropper 6 has a single second protrusion 11 on the bottom of its outer wall. This makes it easier to distinguish the upper dropper 3 from the lower dropper 6 by touch, reducing the probability of incorrect insertion of the upper dropper 3 and the lower dropper 6 during liquid dispensing. It also reduces the probability of liquid mixing between the upper inner bottle 2 and the lower inner bottle 5 to a certain extent, ensuring the normal use of the liquid inside the upper inner bottle 2 and the lower inner bottle 5.

[0027] See attached document Figure 1 The upper inner bottle 2 and the lower inner bottle 5 are different colors, and the second raised strip 11 and the second sealing cap 7 are the same color as the lower inner bottle 5. The first raised strip 10 and the fourth sealing cap 9 are the same color as the upper inner bottle 2. The connecting sleeve 1, the first sealing cap 4 and the third sealing cap 8 are all made of transparent material, which can visually distinguish the correct insertion position of the upper dropper 3 and the lower dropper 6, further reducing the probability of incorrect insertion of the upper dropper 3 and the lower dropper 6 during the liquid dispensing process. To a certain extent, it reduces the probability of the liquid inside the upper inner bottle 2 and the lower inner bottle 5 mixing with each other, ensuring the normal use of the liquid inside the upper inner bottle 2 and the lower inner bottle 5.

[0028] See attached document Figure 3 The outer wall of the upper inner bottle 2 is provided with multiple third protrusions 12. The number of third protrusions 12 is equal to that of the first protrusions 10, and the color of the third protrusions 12 is the same as that of the first protrusions 10. By observing the relationship between the number and color of the third protrusions 12 and the first protrusions 10, it can be seen that the upper inner bottle 2 and the upper dropper 3 are matched, thereby further reducing the probability of incorrect insertion of the upper dropper 3 and the lower dropper 6 during the liquid dispensing process. To a certain extent, it reduces the probability of the liquid inside the upper inner bottle 2 and the lower inner bottle 5 mixing with each other, ensuring the normal use of the liquid inside the upper inner bottle 2 and the lower inner bottle 5.

[0029] See attached document Figure 3 The outer wall of the lower inner bottle 5 is provided with a single fourth protrusion strip 13. The color of the fourth protrusion strip 13 is the same as the color of the second protrusion strip 11. By observing the relationship between the number and color of the fourth protrusion strip 13 and the second protrusion strip 11, it can be seen that the lower inner bottle 5 and the lower dropper 6 are matched. This further reduces the probability of incorrect insertion of the upper dropper 3 and the lower dropper 6 during the liquid dispensing process. To a certain extent, it reduces the probability of the liquid inside the upper inner bottle 2 and the lower inner bottle 5 mixing with each other, ensuring the normal use of the liquid inside the upper inner bottle 2 and the lower inner bottle 5.

[0030] See attached document Figure 2 and attached Figure 3The inner wall of the fourth sealing cap 9 and the outer wall of the upper inner bottle 2, and the inner wall of the second sealing cap 7 and the outer wall of the lower inner bottle 5 are all provided with matching spiral threads. The fourth sealing cap 9 and the upper inner bottle 2, and the second sealing cap 7 and the lower inner bottle 5 are connected by spiral threads, so that the fourth sealing cap 9 is more firmly connected at the top of the upper inner bottle 2 and the third sealing cap 8 is at the bottom of the lower inner bottle 5, thereby improving the sealing performance of the upper inner bottle 2 and the lower inner bottle 5.

[0031] See attached document Figure 1 A double-ended dropper bottle structure, characterized in that: the connecting sleeve 1 is provided with two material bottles, the connecting sleeve 1 and the upper inner material bottle 2, which can hold and carry two different liquids, so that the same dropper bottle can hold different liquids.

[0032] The working principle of this utility model is as follows: The connecting sleeve 1 is equipped with two inner bottles, an upper inner bottle 2 and a lower inner bottle 5, for holding different liquids. During business trips and travels, different cosmetic and skincare liquids can be carried through this dropper bottle structure. At the same time, since the first protrusion 10 on the upper dropper 3 and the third protrusion 12 on the upper inner bottle 2 are the same color and number, and the second protrusion 11 on the lower dropper 6 and the fourth protrusion 13 on the lower inner bottle 5 are the same color and number, the probability of incorrect insertion of the upper dropper 3 and the lower dropper 6 during the liquid dispensing process is reduced. To a certain extent, the probability of the liquids inside the upper inner bottle 2 and the lower inner bottle 5 mixing is reduced, ensuring the normal use of the liquids inside the upper inner bottle 2 and the lower inner bottle 5.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
