Description

Technical Field

[0001] The present application relates to the technical field of plastic packaging, and in particular to a fully plastic cosmetic dropper. Background Art

[0002] Press droppers are widely used in cosmetics. In order to ensure sealing and prevent volatilization of cosmetics, the inner sleeve in the press dropper is usually threadedly connected to the container of the cosmetic liquid. When taking out the dropper, the inner sleeve is driven by the outer sleeve to screw the dropper out of the cosmetic container.

[0003] The length of the existing dropper is often required to be smaller than the length of the cosmetic bottle. If the dropper is longer, the bottom of the dropper will act on the bottom surface of the cosmetic bottle during installation, thereby hindering the normal storage of the dropper. However, the problem caused by the dropper being shorter than the length of the cosmetic bottle is that when the contents of the cosmetic bottle are at the bottom, it is difficult to take liquid out of the dropper, so the last bit of liquid in the cosmetic bottle is difficult to be fully utilized. Summary of the invention

[0004] The purpose of the present application is to provide an all-plastic cosmetic dropper that is easy to use.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: an all-plastic cosmetic dropper, comprising a dropper body, which is used to take liquid from a cosmetic bottle, and the dropper body comprises a dropper head, a first tube body, a folded portion and a second tube body in sequence, the first tube body and the second tube body are respectively connected to the folded portion and form an adsorption channel for liquid flow, the folded portion is completely located inside the first tube body, and the top portion of the second tube body is located inside the folded portion, and arc portions are formed at the connections between the first tube body and the folded portion, and between the second tube body and the folded portion, and when the bottom of the second tube body abuts against the bottom surface of the cosmetic bottle, the arc portion is suitable for deformation to shorten the overall toughness deformation formed by the first tube body, the folded portion and the second tube body.

[0006] Preferably, the folding portion is arched toward one side of the first tube body or the second tube body so that the folding portion forms an arc structure; when the first tube body abuts against the bottom surface of the cosmetic bottle, the arc structure is suitable for forming elastic deformation.

[0007] As a preference, the bottom of the second tube body is a liquid outlet, and a throttling portion is provided above the liquid outlet, and the throttling portion narrows the adsorption channel at that location.

[0008] Preferably, a slow flow chamber is formed below the throttling portion and between the liquid outlet, and the slow flow chamber includes an upper half connected to the throttling portion and a lower half connected to the liquid outlet, and the upper half and the lower half form a chamber structure with a large middle radius and small radii at both ends.

[0009] As a preference, a through groove is formed at the bottom of the liquid outlet, and the through groove penetrates the bottom side wall of the second tube body and enables the inner cavity of the cosmetic bottle to communicate with the inner cavity of the second tube body.

[0010] As a preferred embodiment, the through groove is a cross-shaped groove, and four notches are formed at the bottom of the second tube body.

[0011] As a preference, the cosmetic bottle comprises a bottle mouth, an outer bottle body and an inner bottle body, and the bottom of the inner bottle body becomes smaller from both sides toward the middle to form a tapered structure.

[0012] Preferably, the bottle mouth is provided with an external thread, a fixing portion is formed in the middle and upper part of the dropper body, a cover body is fixedly mounted on the fixing portion, an internal thread is provided on the inner wall of the cover body, and the cover body and the bottle mouth form a threaded fit.

[0013] Preferably, the top of the inner bottle body is sealedly connected to the inner side of the top wall of the outer bottle body, the bottom of the inner bottle body is fixedly connected to the bottom of the outer bottle body, and a sealed partition space is formed between the outer bottle body and the inner bottle body.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] The dropper body which is slightly longer than the cosmetic bottle can be installed in the cosmetic bottle. Due to the setting of the folding part, this can be achieved by deformation of the connection between the first tube body, the second tube body and the folding part. Therefore, when the cosmetic bottle is almost used up, the dropper can be easily taken out. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example:

[0027] Reference Figure 1-5The present embodiment provides an all-plastic cosmetic dropper, comprising a dropper body 1, the dropper body 1 is used to take liquid from a cosmetic bottle 3, the dropper body 1 comprises a dropper head 4, a first tube body 6, a folded portion 11 and a second tube body 10 in sequence, the first tube body 6 and the second tube body 10 are respectively connected to the folded portion 11 and form an adsorption channel for liquid flow, the folded portion 11 is completely located inside the first tube body 6, and the top portion of the second tube body 10 is located inside the folded portion 11, and arc portions are formed at the connection between the first tube body 6 and the folded portion 11, and the second tube body 10 and the folded portion 11. When the bottom of the second tube body 10 abuts against the bottom surface of the cosmetic bottle 3, the arc portion is suitable for deformation to shorten the overall tough deformation formed by the first tube body 6, the folded portion 11 and the second tube body 10. Obviously, when the second tube body 10 leaves the bottom surface of the cosmetic bottle 3, the above-mentioned tough deformation will be restored to return to its original state. In this embodiment, the entire material of the dropper body 1 is plastic. Of course, other suitable materials can be selected according to needs, for example, rubber is used at the dropper head 4 of the dropper body 1; plastic has certain toughness and elasticity, so if an arc portion is provided at the folding portion 11 and the first tube body 6 and the second tube body 10 for transition, the whole formed by the first tube body 6, the second tube body 10 and the folding portion 11 can change in length to a certain extent.

[0028] The significance of the connection between the first tube body 6, the folded portion 11 and the second tube body 10 is that, in the initial state, the overall length formed by the three can be slightly longer than the length of the cosmetic bottle 3, and in the following Figure 2 After the installation shown, it is only necessary to deform the entire interior to be normally stored, and normal storage or use is not affected. Obviously, the length of the cosmetic dropper of the traditional product is generally not longer than the length of the cosmetic bottle 3, because the general dropper body 1 is installed together with the cover body 2, and the cover body 2 is to be covered on the top of the cosmetic bottle 3 for fixed sealing after installation. At this time, if the length of the dropper body 1 is greater than the length of the cosmetic bottle 3, it is difficult to install it into the cosmetic bottle 3 because the existing straight dropper is difficult to deform. The current dropper generally has a certain gap between it and the ground of the cosmetic bottle 3 after installation. When the cosmetics are almost used up, it is difficult for the dropper to take the last part of the liquid because the length of the dropper cannot reach the bottom of the cosmetic bottle 3, which makes it difficult for the user to fully use the items in the cosmetic bottle 3. In this embodiment, the dropper body 1 slightly longer than the cosmetic bottle 3 can be installed in the cosmetic bottle 3. Due to the setting of the folding portion 11, it can be achieved by deformation of the connection between the first tube body 6, the second tube body 10 and the folding portion 11.

[0029] The folding portion 11 may be Figure 3 Generally, the whole body is in a straight line shape, and the overall length of the dropper body 1 is contracted mainly by the deformation of the two arc parts; Figure 4As shown, the folded portion 11 can also be configured to be arched toward one side of the first tube body 6 or the second tube body 10. Figure 4 It is arched toward one side of the first tube body 6 so that the folding portion 11 forms an arc structure; when the first tube body 6 abuts against the bottom surface of the cosmetic bottle 3, the arc structure is suitable for forming elastic deformation; obviously, the arc structure at the folding portion 11 forms a structure similar to a retaining spring, which enables the first tube body 6, the folding portion 11 and the second tube body 10 to better restore their original shape after deformation.

[0030] like Figure 2 , Figure 5 As shown, the bottom of the second tube body 10 is a liquid outlet 12, and a throttling portion 15 is provided above the liquid outlet 12. The throttling portion 15 narrows the adsorption channel there. When the channel is narrowed, the flow rate of the solution inside the dropper is originally slow when the dropper is used, and the narrowed channel can reduce the generation of bubbles or foams to a certain extent. Further, a slow flow chamber 14 is formed between the lower part of the throttling portion 15 and the liquid outlet 12. The slow flow chamber 14 includes an upper part connected to the throttling portion 15 and a lower part connected to the liquid outlet 12. The upper part and the lower part form a chamber structure with a large middle radius and small two-end radius. The throttling portion 15 is to reduce the generation of bubbles or foams, and the chamber structure with a large middle radius at the bottom and a small two-end radius is to enable a certain amount of storage in the slow flow chamber 14 when squeezing out the liquid inside the dropper, so as to prevent the liquid from increasing the flow rate due to the reduction of the flow diameter at the throttling portion 15, thereby causing the liquid to spray out.

[0031] like Figure 5 As shown, a through groove 13 is formed at the bottom of the liquid outlet 12, and the through groove 13 penetrates the bottom side wall of the second tube body 10, and makes the inner cavity of the cosmetic bottle 3 communicate with the inner cavity of the second tube body 10. The through groove 13 is preferably a cross-shaped groove, and four notches are formed at the bottom of the second tube body 10. When the items in the cosmetic bottle 3 are almost used up, the bottom of the dropper body 1 (actually the second tube body 10) will be inserted into the bottom of the cosmetic bottle 3 for suction. At this time, if the liquid outlet 12 at the bottom of the second tube body 10 is connected to the bottom surface of the cosmetic bottle 3, the channel space left between the liquid outlet 12 and the ground of the cosmetic bottle 3 may be very small, which will affect the dropper to absorb liquid. The through groove 13 allows the liquid to enter through the notch there, so as to facilitate the dropper to take the liquid at the bottom.

[0032] like Figure 2 As shown, the cosmetic bottle 3 includes a bottle mouth 7, an outer bottle body 8 and an inner bottle body 9. The bottom of the inner bottle body 9 becomes smaller from both sides toward the middle to form a tapered structure. In this way, when the liquid in the cosmetic bottle 3 reaches the bottom, the liquid in the bottle can be concentrated in the middle of the bottom of the bottle for easy access.

[0033] like Figure 2As shown, the bottle mouth 7 is provided with an external thread, a fixing portion 5 is formed in the middle and upper part of the dropper body 1, the fixing portion 5 is fixedly installed with a cover body 2, the inner wall of the cover body 2 is provided with an internal thread, and the cover body 2 and the bottle mouth 7 form a threaded fit to facilitate the installation of the cover body 2 and the dropper body 1.

[0034] The top of the inner bottle body 9 is sealed to the inner side of the top wall of the outer bottle body 8, and the bottom of the inner bottle body 9 is fixedly connected to the bottom of the outer bottle body 8. A sealed partition space is formed between the outer bottle body 8 and the inner bottle body 9, and the partition space can ensure that the cosmetic bottle 3 has a certain heat insulation and buffering capacity.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
