Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a spreadable emulsion bottle. Background Technology

[0002] Currently, most cosmetics are in the form of lotions or emulsions, such as lotions, serums, toners, makeup removers, and foundations. These cosmetics are packaged in glass or plastic bottles. To use them, pour the liquid out or squeeze it into your palm, then apply it evenly to your skin.

[0003] When pouring or squeezing, some of the lotion will adhere to the palm and be absorbed, easily causing waste. Subsequently, a Chinese utility model patent, such as CN2829444Y (authorization announcement number CN2829444Y) dated October 25, 2006, disclosed a device for packaging cosmetics, including a container and a container cap. The container includes a container opening with a cavity inside. The cavity is shaped like a spherical surface with a crown removed from both the top and bottom ends. A ball bearing is installed inside the cavity of the container opening, and the size of the ball bearing matches the cavity of the container opening. In use, simply rub the ball bearing against the area to be applied and gently squeeze the container wall to evenly apply the cosmetic.

[0004] Existing cosmetic packaging devices can evenly apply lotion to the skin using rollers. However, the roller movement alone cannot ensure that the lotion is smoothly discharged. If the squeezing force is high, too much liquid will be wasted, while if the squeezing force is low, the liquid will be insufficient. It is difficult to accurately control the squeezing force and the amount of liquid discharged. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing cosmetic packaging bottles only have ball bearing movement, which cannot smoothly discharge water and lotion. If the squeezing force is large, more liquid is discharged, which is easy to waste. Conversely, if the squeezing force is small, the liquid discharge is insufficient, and it is difficult to accurately control the squeezing force and the amount of liquid discharged.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a spreadable lotion bottle:

[0007] The emulsion bottle includes a bottle body, a fixing sleeve, a ball bearing, and a pump structure. The bottle body has a liquid storage chamber inside and a liquid outlet at one end. The fixing sleeve is connected to one end of the bottle body, and the ball bearing is installed in the fixing sleeve. The ball bearing and the liquid outlet are spaced apart along the length of the bottle body.

[0008] The pump structure includes a compressible container, a liquid storage tank, and an elastic element. The compressible container is installed between the liquid outlet and the ball bearing. The compressible container is provided with a first interface and a second interface. The first interface is connected to a suction tube that passes through the liquid outlet to the liquid storage chamber. The second interface is arranged opposite to the ball bearing.

[0009] The liquid storage tank is installed on the side of the compressible container facing the ball bearing. The liquid storage tank is connected to the second interface. The elastic element is disposed between the liquid storage tank and the bottle body. The first interface is equipped with a first one-way valve, and the second interface is equipped with a second one-way valve.

[0010] Furthermore, the first check valve is directed from the liquid storage chamber to the compressible container, and the second check valve is directed from the compressible container to the liquid storage tank.

[0011] Furthermore, the first one-way valve includes a conical valve body and a gravity valve ball. The conical valve body has a conical flared opening that is wider at the top and narrower at the bottom, and the gravity valve ball is floatingly installed in the conical flared opening.

[0012] Furthermore, the second one-way valve is an elastic diaphragm, which is used to tilt up when squeezing out liquid to allow the water emulsion to enter the storage tank, and to close the second port when releasing the suction to keep the water emulsion in the storage tank.

[0013] Furthermore, the compressible container is any one of a spherical bladder, a cylindrical bladder, or a corrugated bladder, and the elastic element is a cylindrical compression spring, which is sleeved on the outside of the compressible container.

[0014] Furthermore, along the length of the bottle body, the projected outline of the liquid storage tank is larger than the outer outline of the compressible container, and the edge of the liquid storage tank is engaged with the elastic element.

[0015] Furthermore, the liquid storage tank has an inner flange inside, which protrudes upward relative to the bottom surface of the liquid storage tank. The inner flange is arranged in a spiral shape around the second interface, and the ball bearing is pressed against the inner flange.

[0016] Furthermore, the edge of the liquid storage tank is also provided with a protective cover, which has a flared opening that gradually widens from the liquid storage tank to the ball bearing.

[0017] Furthermore, an annular sponge ring is installed on the inner wall of the fixing sleeve. The annular sponge ring is arranged around the outside of the ball and the liquid storage tank, and the ball and the annular sponge ring are in clearance fit.

[0018] Furthermore, the fixing sleeve and the bottle body are an integral structure.

[0019] Compared with existing technologies, the advantages of this applicator-type lotion bottle are as follows: The bottle adopts a design consisting of a bottle body, a fixing sleeve, a ball bearing, and a pump structure. The bottle body has an internal storage chamber. The fixing sleeve is connected to one end of the bottle body corresponding to the liquid outlet. The ball bearing is installed in the fixing sleeve, spaced apart from the liquid outlet. The compressible container of the pump structure is installed between the liquid outlet and the ball bearing. The storage chamber stores the lotion / lotion. The pump structure draws the lotion / lotion into the compressible container. Pressing the ball bearing squeezes the compressible container, discharging the lotion / lotion into the storage tank and contacting the lower surface of the ball bearing, thereby achieving the purpose of spraying a measured amount of lotion / lotion onto the ball bearing.

[0020] The compressible container has a first interface and a second interface. The first interface is connected to a pipette that extends into the liquid storage chamber, and the second interface is arranged opposite to the ball bearing. A liquid storage tank is installed on the side of the compressible container facing the ball bearing and is connected to the second interface. An elastic element is disposed between the liquid storage tank and the bottle body. A first one-way valve is installed on the first interface, and a second one-way valve is installed on the second interface. The pumping structure is a manually operated pump. The compressible container is connected to the liquid storage chamber through the first interface and the pipette, and is also connected to the liquid storage tank through the second interface. The compressible container forms a metering pumping space between the liquid storage chamber and the liquid storage tank.

[0021] In use, first press the ball bearing. The ball bearing overcomes the elastic force of the elastic element and squeezes the compressible container. At this time, the first one-way valve closes and the second one-way valve opens, allowing air or water emulsion in the compressible container to be discharged upwards from the second interface. This then sprays a measured amount of water emulsion from the compressible container onto the lower surface of the ball bearing. Finally, the ball bearing rolls to ensure even application. Releasing the ball bearing causes the elastic element to expand and extend the compressible container. At this time, the first one-way valve opens and the second one-way valve closes. The water emulsion in the storage chamber can be drawn into the compressible container through the suction tube, while preventing the water emulsion in the storage tank from flowing back into the compressible container, ensuring that the water emulsion in the storage tank can be fully adhered and utilized. A single press can pump out a measured amount of water emulsion. Compared with existing cosmetic packaging bottles, this avoids the difficulty in controlling the liquid volume by squeezing the bottle body, improving the accuracy of the application amount.

[0031] like Figures 1 to 4As shown, an embodiment of the present invention provides a topical emulsion bottle, comprising a bottle body 1, a fixing sleeve 2, a ball bearing 3, and a pumping structure 4. The bottle body 1 has a liquid storage chamber 10 inside, and a liquid outlet 11 is provided at one end of the bottle body 1. The fixing sleeve 2 is connected to one end of the bottle body 1, and the ball bearing 3 is installed in the fixing sleeve 2. The ball bearing 3 and the liquid outlet 11 are spaced apart along the length of the bottle body 1. The pumping structure 4 includes a compressible container 40, a liquid storage tank 41, and an elastic element 42. The compressible container 40 is installed between the liquid outlet 11 and the ball bearing 3.

[0032] The compressible container 40 is provided with a first interface 44 and a second interface 45. The first interface 44 is connected to a pipette 46 that passes through the liquid outlet 11 to the liquid storage chamber 10. The second interface 45 is arranged opposite to the ball bearing 3. The liquid storage tank 41 is installed on the side of the compressible container 40 facing the ball bearing 3. The liquid storage tank 41 is connected to the second interface 45. An elastic element 42 is disposed between the liquid storage tank 41 and the bottle body 1. The first interface 44 is equipped with a first one-way valve 47, and the second interface 45 is equipped with a second one-way valve 48.

[0033] This applicator lotion / emulsion bottle features a bottle body 1, a retaining sleeve 2, a roller ball 3, and a pump structure 4. The bottle body 1 has a storage chamber 10 inside. The retaining sleeve 2 is connected to one end of the bottle body 1 corresponding to the outlet 11. The roller ball 3 is installed in the retaining sleeve 2, spaced apart from the outlet 11. The compressible container 40 of the pump structure 4 is installed between the outlet 11 and the roller ball 3. The storage chamber 10 stores the lotion / emulsion. The pump structure 4 draws the lotion / emulsion into the compressible container 40. Pressing the roller ball 3 squeezes the compressible container 40, discharging the lotion / emulsion into the storage tank 41, where it contacts the lower surface of the roller ball 3, thus achieving the purpose of spraying a measured amount of lotion / emulsion onto the roller ball 3.

[0034] The compressible container 40 is provided with a first interface 44 and a second interface 45. The first interface 44 is connected to a pipette 46 that extends through to the liquid storage chamber 10, and the second interface 45 is arranged opposite to the ball bearing 3. A liquid storage tank 41 is installed on the side of the compressible container 40 facing the ball bearing 3, and the liquid storage tank 41 is connected to the second interface 45. An elastic element 42 is disposed between the liquid storage tank 41 and the bottle body 1. A first one-way valve 47 is installed on the first interface 44, and a second one-way valve 48 is installed on the second interface 45. The pumping structure 4 is a manually operated pump. The compressible container 40 is connected to the liquid storage chamber 10 through the first interface 44 and the pipette 46, and is also connected to the liquid storage tank 41 through the second interface 45. The compressible container 40 forms a metering pumping space between the liquid storage chamber 10 and the liquid storage tank 41.

[0035] In use, first press the ball bearing 3. The ball bearing 3 overcomes the elastic force of the elastic element 42 and squeezes the compressible container 40. At this time, the first one-way valve 47 closes and the second one-way valve 48 opens, allowing air or water emulsion in the compressible container 40 to be discharged upwards from the second interface 45. This then quantitatively sprays the water emulsion from the compressible container 40 onto the lower surface of the ball bearing 3, and finally, the ball bearing 3 rolls to evenly coat the emulsion. Releasing the ball bearing 3 causes the elastic element 42 to expand the compressible container 40. At this time, the first one-way valve 47 opens and the second one-way valve 48 closes. The water emulsion in the storage chamber 10 can be drawn into the compressible container 40 through the suction tube 46, while preventing the water emulsion in the storage tank 41 from flowing back into the compressible container 40, ensuring that the water emulsion in the storage tank 41 can be fully adhered and utilized. A single press can quantitatively pump out the water emulsion, which, compared to existing cosmetic packaging bottles, avoids the difficulty in controlling the liquid volume by squeezing the bottle body, improving the accuracy of the application amount.

[0036] In this embodiment, the first one-way valve 47 is open from the liquid storage chamber 10 to the compressible container 40, and the second one-way valve 48 is open from the compressible container 40 to the liquid storage tank 41. When the ball bearing 3 is pressed, the second one-way valve 48 is open, allowing air or water emulsion in the liquid storage chamber 10 to enter the liquid storage tank 41; when the ball bearing 3 is released, the elastic element 42 causes the compressible container 40 to expand and reset, and the first one-way valve 47 is open, allowing the water emulsion in the liquid storage chamber 10 to be drawn into the compressible container 40. The metered pumping operation can be completed by pressing and releasing.

[0037] As a further preferred embodiment, the first one-way valve 47 includes a conical valve body 471 and a gravity valve ball 472. The conical valve body 471 has a conical flared opening that is wider at the top and narrower at the bottom, and the gravity valve ball 472 is floatingly installed in the conical flared opening. The density of the gravity valve ball 472 is greater than the density of the water emulsion. Specifically, the gravity valve ball 472 is a steel valve ball. The gravity valve ball 472 can automatically fall into the water emulsion and reliably seal the conical flared opening of the conical valve body 471, thereby achieving the functions of smooth liquid inflow and backflow prevention.

[0038] Correspondingly, the second one-way valve 48 is an elastic diaphragm. The elastic diaphragm is used to tilt upwards during squeezing to allow the water emulsion to enter the storage tank 41, and to close the second port 45 when the suction is released to keep the water emulsion in the storage tank 41. The structure of the elastic diaphragm is simpler. Under normal conditions, the elastic diaphragm is attached and closes the second port 45. When the compressible container 40 is subjected to squeezing force, the water emulsion in the compressible container 40 pushes open the elastic diaphragm through the second port 45, ensuring that the water emulsion flows smoothly into the storage tank 41.

[0039] It should be noted that the compressible container 40 can be any one of a spherical bladder, a cylindrical bladder, or a corrugated bladder, and the elastic element 42 is a cylindrical compression spring, which is sleeved on the outside of the compressible container 40. Furthermore, along the length of the bottle body 1, the projected contour of the liquid storage tank 41 is larger than the outer contour of the compressible container 40, and the edge of the liquid storage tank 41 engages with the elastic element 42. The elastic element 42 generates an elastic restoring force on the compressible container 40, while ensuring that the ball bearing 3 remains stably positioned away from the outlet 11 when released.

[0040] The liquid storage tank 41 has an inner flange 410 inside, which protrudes upward relative to the bottom surface of the liquid storage tank 41. The inner flange 410 is arranged in a spiral around the second interface 45, and the ball bearing 3 is press-fitted with the inner flange 410. It is precisely this spiral inner flange 410 design that forms a spiral liquid storage space inside the liquid storage tank 41, which can reliably buffer the pumped emulsion. At the same time, the edge of the liquid storage tank 41 is also provided with a protective cover 411. The protective cover 411 has a flared mouth that gradually widens from the liquid storage tank 41 to the ball bearing 3. The protective cover 411 can prevent the emulsion from splashing to the outside of the liquid storage tank 41, effectively avoiding the overflow and waste of the emulsion.

[0041] In addition, an annular sponge ring 5 is installed on the inner wall of the fixing sleeve 2. The annular sponge ring 5 is arranged around the outer side of the ball bearing 3 and the liquid storage tank 41, and the ball bearing 3 and the annular sponge ring 5 are in clearance fit. The fixing sleeve 2 and the bottle body 1 are an integral structure, which improves the production efficiency of the emulsion bottle. In order to meet different usage needs, a gravity ball can also be installed at the end of the straw 46. The gravity ball moves with the flow of the emulsion in the bottle, ensuring that the inlet of the straw 46 is always immersed in the emulsion, thereby improving the reliability of the emulsion intake.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
