Description

Technical Field

[0001] This invention relates to the field of cosmetic container technology, specifically to a recyclable, single-material, environmentally friendly self-priming dropper container. Background Technology

[0002] Essential oils have a long history, primarily extracted from the roots, stems, and leaves of plants. They contain active ingredients and possess significant application value. Plant essential oils, also known as volatile oils or fragrance oils, are aromatic, oily liquids widely used in the manufacture of perfumes, facial cleansers, skincare products, and other cosmetics, offering antioxidant and skin-nourishing benefits. However, existing essential oil dropper containers often leave residue at the bottom, preventing complete use and resulting in waste. These dropper containers are generally used for essential oils. Conventional droppers typically consist of multiple materials, including a soft rubber tip, a glass dropper, and a plastic cap, leading to low recycling rates. Furthermore, existing self-priming dropper containers have complex structures and metal springs, sometimes resulting in inaccurate dispensing and even spraying when pressed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a recyclable, single-material, environmentally friendly self-priming dropper container, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a recyclable, single-material, environmentally friendly self-priming dropper container, comprising a bottle body, a notch at the top of the bottle body, a shoulder sleeve installed on the outer side of the notch, an inner plug installed in the middle of the notch, an inner cap threadedly connected to the outer side of the notch, an outer cap fixedly connected to the outer side of the inner cap, a rubber cap installed on the top of the outer cap, the bottom end of the rubber cap extending into the interior of the inner cap and fitted with a retaining ring, a fixing ring installed on the outer side of the bottom end of the retaining ring, a limiting support rod installed inside the bottom end of the retaining ring, a piston sleeved on the outer side of the limiting support rod, a dropper body installed on the outer side of the fixing ring and the piston, the bottom end of the limiting support rod located inside the dropper body, the bottom end of the dropper body passing through the inner plug and extending into the interior of the bottle body, a second latching part provided on the outer side of the dropper body, and a first latching part provided on the inner side of the inner plug at a position corresponding to the second latching part.

[0005] Optionally, a bottom plate is provided at the bottom of the bottle.

[0006] Optionally, the bottom of the inner cavity of the bottle is provided with a groove, and the bottom of the inner cavity of the bottle is inclined towards the groove.

[0007] Optionally, the first latching part and the second latching part cooperate to form a latching structure.

[0008] Optionally, the shape and size of the dropper head are adapted to the shape and size of the groove cavity.

[0009] Optionally, the limiting support rod is connected to the inside of the rubber cap, and a vent hole is provided on the outside of the limiting support rod, which is connected to the inside of the dropper body through the vent hole.

[0010] This invention provides a recyclable, single-material, environmentally friendly self-priming dropper container, which has the following beneficial effects: 1. This recyclable, single-material, environmentally friendly self-priming dropper container features a limiting support rod, piston, and dropper body. When the user twists the outer cap, the second and first locking parts form a locking structure that keeps the dropper body and inner stopper stationary. The outer cap moves the retaining ring, fixing ring, piston, and limiting support rod upwards, causing the piston to shift relative to the dropper body. This draws the liquid from inside the bottle into the dropper body, achieving self-priming. The dropper body can then be completely pulled out of the bottle, and the user only needs to squeeze the cap to dispense a measured amount of liquid.

[0011] 2. This recyclable, single-material, environmentally friendly self-priming dropper container features a groove and a dropper body. The bottom of the bottle's inner cavity slopes towards the groove, creating a shape that is high around the edges and low in the middle. This allows the cosmetic material inside the bottle to concentrate in the groove for the dropper body to draw it in, achieving zero residue inside the bottle and fully utilizing the material. This container only requires controlling the wall thickness of the environmentally friendly material; as long as it can be extruded, all other components can be made from the same environmentally friendly material, thus achieving 100% recyclability of a single material.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] Please see Figures 1 to 7 This invention provides a technical solution: a recyclable, single-material, environmentally friendly self-priming dropper container, comprising a bottle body 1, a notch 2 at the top of the bottle body 1, a shoulder sleeve 3 installed on the outer side of the notch 2, an inner plug 4 installed in the middle of the notch 2, an inner cap 7 threadedly connected to the outer side of the notch 2, an outer cap 5 fixedly connected to the outer side of the inner cap 7, a rubber cap 6 installed on the top of the outer cap 5, the bottom end of the rubber cap 6 extending into the interior of the inner cap 7 and fitted with a retaining ring 8, a fixing ring 9 installed on the outer side of the bottom end of the retaining ring 8, a limiting support rod 11 installed inside the bottom end of the retaining ring 8, and a piston 10 sleeved on the outer side of the limiting support rod 11. The dropper body 12 is installed on the outside of the fixing ring 9 and the piston 10. The bottom end of the limiting support rod 11 is located inside the dropper body 12. The bottom end of the dropper body 12 passes through the inner plug 4 and extends into the inside of the bottle body 1. A second latching part 15 is provided on the outside of the dropper body 12. A first latching part 14 is provided on the inside of the inner plug 4 and at the position corresponding to the second latching part 15. The wall thickness is controlled by various environmentally friendly materials. As long as the material can be squeezed out, all other parts can use the same material to achieve 100% recyclability of a single material. The materials can be selected from environmentally friendly materials such as HDPE, LDPE, and PP.

[0016] The bottom of the bottle body 1 is provided with a base plate 13.

[0017] The bottom of the inner cavity of the bottle body 1 is provided with a groove 16. The bottom of the inner cavity of the bottle body 1 is inclined towards the groove 16, so that the cosmetic material inside the bottle body 1 is concentrated inside the groove 16, so that the dropper body 12 can draw it up, thereby enabling the container to achieve zero residue of the material inside the bottle body 1.

[0018] The first latching part 14 and the second latching part 15 cooperate to form a latching structure. Through the latching structure formed by the user, when the user twists the outer cover 5, the latching structure formed by the second latching part 15 and the first latching part 14 keeps the dropper body 12 and the inner stopper 4 stationary. The outer cover 5 drives the retaining ring 8, the fixing ring 9, the piston 10 and the limiting support rod 11 to move upward, so that the piston 10 is displaced a certain distance relative to the dropper body 12, sucking the material inside the bottle 1 into the dropper body 12, realizing the self-suction function. Then, the outer cover 5 is twisted to pull the dropper body 12 out from the bottle 1, and the material inside the dropper body 12 is taken out. By adjusting the distance of the piston 10 relative to the dropper body 12 and the size of the cavity between the dropper body 12 and the piston 10, different specifications of liquid output can be achieved.

[0019] The shape and size of the dropper body 12 head end are adapted to the shape and size of the groove 16 inner cavity, so that the head end of the dropper body 12 can be inserted into the groove 16 to draw up the material collected in the groove 16 from the inner cavity of the bottle body 1.

[0020] The limiting support rod 11 is connected to the inside of the cap 6. A vent hole 17 is provided on the outside of the limiting support rod 11. The limiting support rod 11 is connected to the inside of the dropper body 12 through the vent hole 17. When the container is in the locked state, the bottom end of the limiting support rod 11 is inserted into the pipe of the dropper body 12 to seal the vent hole 17.

[0021] In summary, this recyclable, single-material, environmentally friendly self-priming dropper container allows the user to manually unscrew the outer cap 5. The second snap-fit ​​part 15 and the first snap-fit ​​part 14, forming a snap-fit ​​structure, keep the dropper body 12 and the inner stopper 4 stationary. The outer cap 5 then moves the retaining ring 8, the fixing ring 9, the piston 10, and the limiting rod 11 upwards, causing the piston 10 to shift 3.8mm relative to the dropper body 12, drawing the material from inside the bottle 1 into the dropper body 12. Further unscrewing of the outer cap 5 disengages the second snap-fit ​​part 15 from the first snap-fit ​​part 14. The outer cap 5 then moves the retaining ring 8, the fixing ring 9, the piston 10, the limiting rod 11, and the dropper body 12 upwards, completely pulling the dropper body 12 out of the bottle 1. The user then gently squeezes the cap 6, allowing the gas inside the cap 6 to enter the dropper body 12 through the limiting rod 11 and the vent 17, squeezing out the material and achieving quantitative liquid dispensing.

[0022] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
