Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic packaging, in particular to a container quantitative structure. Background Art

[0002] Cosmetics have gone through hundreds of years of development, from the initial simple natural ingredient preparations to today's complex products with various high-tech ingredients and formulas. The development of cosmetics continues to promote innovation and progress in various industries. For example, the bottling industry. Nowadays, there are many types of packaging bottles on the market, with various materials, shapes and functions. In terms of shape, traditional cylindrical packaging bottles are no longer the only choice. Various novel designs continue to emerge, including square, spiral, heart-shaped, animal-shaped and other forms, which not only improve the beauty of the packaging bottles, but also increase the attractiveness and recognition of the products. In terms of function, in addition to the basic storage function, modern packaging bottles also have a variety of functions such as heat preservation, quantitative, and sun protection to meet people's demand for the functionality of packaging bottles.

[0003] Among them, the quantitative packaging bottle has quite important practical value, for example:

[0004] CN220997507U discloses an inverted quantitative cup container, comprising: a bottle body, one end of which is open, and the other end is sealed and has a hemispherical structure; a quantitative cup, which is detachably arranged at the open end of the bottle body, and one side of the quantitative cup is provided with a through groove communicating with the inner cavity of the bottle body; a discharge pipe, which is arranged at the opening of the quantitative cup; and a sealing cover, which is threadedly connected to the discharge pipe. The quantitative cup of the container is built-in, and the liquid is transferred between the bottle body and the quantitative cup through the through groove, and the liquid is quantified by the volume of the quantitative cup itself; the sealed end of the bottle body is a hemispherical structure, so that the bottle body is in an inverted state, which can ensure that the liquid fully enters the inside of the quantitative cup. However, when the container is actually used, it is necessary to avoid the quantitative cup from tilting to the side of the through groove, otherwise the liquid will be poured into the bottle body again, causing the problem of inaccurate quantification.

[0005] CN105616165A discloses a quantitative drug dispensing device for bottled drugs, wherein the inner wall of the connecting cover is provided with an internal thread C, a transparent drug dispensing tube is provided in the middle of the upper surface of the connecting cover, a scale is provided on the transparent drug dispensing tube, an external thread A is provided on the outer edge surface of the sleeve ring of the transparent drug dispensing tube, a sealing ring provided on the outer edge surface of the piston is interference fit with the inner wall of the transparent drug dispensing tube, the ball is in an inverted conical hole, the external thread B on the outer edge surface of the retaining ring is connected to the internal thread B of the piston, the upper and lower ends of the spring are respectively pressed on the opposite surfaces of the retaining ring and the ball, and an oblong hole is provided in the middle of the retaining ring. The quantitative drug dispensing device uses a spring to make the ball block the inverted conical hole to prevent the liquid in the drug dispensing tube from flowing back into the medicine bottle, thereby achieving the purpose of quantitative dispensing. However, in actual application, the drug dispensing device needs to avoid the problem of blocking failure caused by the movement of the ball, which requires that each time it is used, it is best to disassemble the drug dispensing device separately to avoid the liquid in the medicine bottle from rushing out of the ball when pouring and causing blocking failure. In addition, this structure is difficult to apply to emulsion fluids.

[0006] Based on this, the technical problem solved in this case is: how to solve the problem of complex structure of the quantitative structure of the container of the quantitative bottle and the limited angle and usage during use. Utility Model Content

[0019] In the above-mentioned quantitative container structure, the ratio of the capacity of the upper liquid storage chamber to the capacity of the lower liquid storage chamber is 1.5-2.0, including but not limited to 1.5, 1.6, 1.7, 1.8, 1.9, and 2.0.

[0020] In the above-mentioned container quantitative structure, the tube body is a structure that is narrow at the top and wide at the bottom; the outer diameter of the quantitative tube matches the inner diameter of the narrow end of the tube body;

[0021] When the quantitative tube is pushed out of the tube body by the elastic element, the liquid inlet and outlet of the quantitative tube are sealed and matched with the side wall of the tube body.

[0024] In the above-mentioned container quantitative structure, a limiting portion is provided on the outer periphery of the quantitative tube; the limiting portion cooperates with the wide end of the tube body and is used to prevent the axis of the quantitative tube from shifting and / or one end of the elastic element is connected to the limiting portion and the other end of the elastic element is connected to the tube body.

[0025] In the above-mentioned container quantitative structure, the lower end of the tube body is provided with a mounting groove; a bottom plate is provided in the mounting groove; one end of the elastic element is connected to the quantitative tube, and the other end of the elastic element is connected to the bottom plate;

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Example 1

[0043] refer to Figures 1 to 6 A container quantitative structure comprises a tube body 1, a quantitative tube 2, an elastic element 3, and a cover body 4, wherein the upper and lower ends of the tube body 1 are both open; the quantitative tube 2 is located in the tube body 1; the upper end of the quantitative tube 2 is an open side, and the lower end is a closed side, and the side wall of the quantitative tube 2 is provided with a liquid inlet and outlet 101; the upper end of the elastic element 3 is connected to the quantitative tube 2, and the lower end of the elastic element 3 is connected to the tube body 1; in this embodiment, the quantitative tube 2 is installed on an external narrow-mouth bottle, and the cover body 4 is a bottle cap of the narrow-mouth bottle (hereinafter, the container after the quantitative structure is installed on the narrow-mouth bottle is referred to as a quantitative bottle);

[0044] When the cover body 4 is covered on the upper end of the tube body 1, the quantitative tube 2 is held between the elastic element 3 and the cover body 4 by the elastic element 3 and the liquid inlet and outlet 101 is opened;

[0045] When the cover body 4 is away from the upper end of the tube body 1 , the quantitative tube 2 is pushed out from the tube body 1 by the elastic element 3 and closes the liquid inlet and outlet 101 .

[0046] The liquid inlet and outlet 101 is arranged on the side wall of the quantitative tube 2, and the quantitative tube 2 forms an upper liquid storage chamber a and a lower liquid storage chamber b.

[0047] It should be noted that the quantitative structure of this embodiment needs to be used in conjunction with a container, including but not limited to bottles, bags, barrels, etc.; it needs to be connected to the bottleneck of the bottle, the mouth of the bag, the mouth of the barrel, etc. For more specific connection methods, please refer to Example 2 and Example 3;

[0048] The method of using this embodiment is as follows: In the initial state (such as Figure 3 ), that is, when the cover body 4 covers the upper end of the tube body 1, the user turns the entire quantitative bottle upside down (such as Figure 4 ), so that the liquid in the quantitative bottle enters the quantitative tube 2 through the liquid inlet and outlet 101, at which time the liquid is concentrated in the upper liquid storage chamber a, and then the user restores the quantitative bottle to the upright position (such as Figure 5 ), at this time, part of the liquid in the upper liquid storage chamber a will flow back into the narrow-mouth bottle through the liquid inlet and outlet 101, and the other part will flow into the lower liquid storage chamber b to complete the quantitative measurement. Finally, the user opens the cover body 4 and makes the cover body 4 away from the upper end of the tube body 1. At this time, the elastic element 3 will bounce the quantitative tube 2 and block the liquid inlet and outlet 101 (such as Figure 6 ), thereby ensuring that the quantitative amount remains unchanged, and at the same time enabling the user to pour out the quantitative liquid in the quantitative tube 2 at all angles.

[0049] Compared with CN220997507U, the advantage of this embodiment is that by setting the elastic element 3, the cover body 4, and the liquid inlet and outlet 101 to be sealed when the quantitative tube 2 is pushed out, the liquid inlet and outlet 101 can be automatically closed to prevent the liquid from flowing back into the container from the liquid inlet and outlet 101 when pouring the liquid.

[0050] At the same time, the closed liquid inlet and outlet 101 can also prevent the liquid in the container from flowing out from the liquid inlet and outlet 101 to the outside when the liquid in the container is relatively full.

[0051] The above design significantly improves the quantitative accuracy of the quantitative structure.

[0052] In addition, the design of the automatic ejection metering tube 2 of the present embodiment can maintain the sealing of the liquid in the container, avoid its continuous contact with the atmosphere, and reduce the risk of contamination and oxidation of the liquid in the bottle; especially when the liquid is essential oil, essential oil is particularly susceptible to oxidation. In the design of the present embodiment, this risk can be significantly reduced.

[0053] Preferably, the liquid inlet and outlet 101 is arranged at the lower half of the quantitative tube 2 to form an upper liquid storage chamber a and a lower liquid storage chamber b.

[0054] In practical applications, the ratio of the capacity of the upper liquid storage chamber a to the capacity of the lower liquid storage chamber b is not less than 1.2. The above design can ensure that the lower liquid storage chamber b can obtain enough liquid to fill its volume.

[0055] In this embodiment, preferably, the ratio of the capacity of the upper liquid storage chamber a to the capacity of the lower liquid storage chamber b is 1.5. This design is based on the overall preference of this embodiment. Specifically, when the quantitative bottle is restored, it is inevitable that part of the liquid in the quantitative tube 2 will return to the narrow-mouth bottle. Under this design, the capacity of the upper liquid storage chamber a is significantly greater than the capacity of the lower liquid storage chamber b, which makes the liquid in the upper liquid storage chamber a completely emptied during the restoration process, but it needs to stay for a period of time before it is emptied to achieve the purpose of precise quantitative measurement. Of course, the ratio of the capacity of the upper liquid storage chamber a to the capacity of the lower liquid storage chamber b can also be preferably 1.6, 1.7, 1.8, 1.9, 2.0. In actual use, the larger the multiple, the more the user needs to increase the upright time of the quantitative bottle after restoration to avoid the liquid in the upper liquid storage chamber a not being completely discharged back to the narrow-mouth bottle from the liquid inlet and outlet 101.

[0056] Specifically, the tube body 1 is a structure that is narrow at the top and wide at the bottom; the outer diameter of the quantitative tube 2 matches the inner diameter of the narrow end of the tube body 1; when the quantitative tube 2 is pushed out of the tube body 1 by the elastic element 3, the liquid inlet and outlet 101 of the quantitative tube 2 and the side wall of the tube body 1 are sealed and matched.

[0057] In this embodiment, the tube body 1 is composed of an inner tube body 11 and an outer tube body 12. The outer tube body 12 is a hard tube body and is used to be fixedly connected to an external container; the inner tube body 11 is fixed in the outer tube body 12, and the inner tube body 11 is a flexible tube body. Preferably, the inner tube body 11 of this embodiment itself is a complete sealing ring. Under this design, the tube body 1 of this embodiment can be directly mounted on a narrow-mouth bottle for direct use.

[0058] In this embodiment, the elastic element 3 is a spring.

[0059] As a preferred embodiment of the present invention, a limiting portion 110 is provided on the outer periphery of the quantitative tube 2; the limiting portion 110 cooperates with the wide end of the tube body 1 and is used to prevent the axis of the quantitative tube 2 from deviating. Under this preferred embodiment, on the one hand, the limiting portion 110 has the function of limiting the moving distance of the quantitative tube 2, and on the other hand, the limiting portion 110 ensures that the quantitative tube 2 remains vertical in the accommodating cavity and also remains vertical during the moving process, further ensuring the accuracy of quantitative determination.

[0060] As a further preferred embodiment of the present invention, a mounting groove 102 is disposed at the lower end of the tube body 1 ; a bottom film 103 is disposed in the mounting groove 102 .

[0061] In the above-mentioned preferred and further preferred embodiments, one end of the spring is connected to the limiting portion 110, and the other end of the spring is connected to the bottom plate 103. This design simply realizes the structural requirements for installing the spring.

[0062] In this embodiment, the liquid inlet and outlet 101 are two strip-shaped holes symmetrically arranged on both sides of the quantitative tube 2. The advantage of this design is that it can be applied to quantitative emulsions and other liquids with poor fluidity. Of course, in other embodiments, the liquid inlet and outlet 101 can be a round hole, etc., and when designing, it is only necessary to pay attention to the lowest liquid inlet and outlet 101 as the quantitative standard.

[0063] In this embodiment, in order to further enhance the sealing performance and prevent the liquid from flowing out of the quantitative tube 2 and the tube body 1 during the inversion process, the upper end of the tube body 1 overlaps the bottle mouth of the narrow-mouth bottle and is flush with its outer circumference; the tube body 1 is provided with a groove 104; and the cover body 4 is provided with a convex portion 105 that can enter the groove 104. The above design also provides support for the spring.

[0064] Specifically, the outer periphery of the lower end of the tube body 1 abuts against the inner periphery of the mouth of the narrow-mouth bottle. The above design is a common technical means used by those skilled in the art, so no additional description is given in this embodiment.

[0065] In this embodiment, the cover body 4 is connected to the bottle mouth of the narrow-mouth bottle by a thread. Of course, in this embodiment, the connection of the cover body 4 is not limited to the threaded connection. In some embodiments, other methods can also be used to connect the cover body 4, such as snap-fit ​​and other technical means commonly used by technicians in the field.
