Description

Technical Field

[0001] This utility model relates to a dropper ball press bottle. Background Technology

[0002] The variety of cosmetics on the market is becoming increasingly diverse, including creams, powders, and liquids. They are produced to meet the different usage situations and needs of users. Liquid cosmetics are applied to the skin. The usual way to use liquid cosmetics is to pour the liquid into the palm of your hand and then apply it to the appropriate area. However, it is difficult to use the liquid in a measured way by pouring it out. Therefore, some manufacturers use straws to draw a certain amount of liquid for storage and then squeeze out the liquid as needed. This type of straw cosmetic still requires massaging with your hands after pressing the liquid to drip out, which is a cumbersome process. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a dropper rollerball press bottle. Liquid cosmetics are drawn into the straw through the elastic suction head, and then the rollerball at the bottom of the straw is rolled on the area to be coated by slight squeezing or direct application. The rolling action of the rollerball can apply the cosmetics more evenly and is easy to operate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dropper-type push-button bottle includes an elastic suction head, a straw, a ball bearing, an outer bottle, and an outer cap. The straw is a tubular structure extending vertically, with a storage cavity inside. The lower end of the straw has a circular groove communicating with the storage cavity. The elastic suction head is detachably connected to the upper opening of the straw. The ball bearing is embedded in and rotatably connected to the circular groove. The straw extends from top to bottom into the outer bottle. The diameter of the bottle opening of the outer bottle is 13-23 mm. The inner cavity of the outer cap has a downwardly extending tubular screw-in part. The inner side wall of the screw-in part has an internal thread. The outer side wall of the bottle opening of the outer bottle has an external thread that mates with the internal thread. The upper end face of the screw-in part has a through hole penetrating the outer cap. The elastic suction head is detachably connected to the through hole.

[0005] It also includes a sealing element made of elastic material, which is nested at the mouth of the outer bottle. The center of the sealing element has a receiving cavity for the straw to pass through. The receiving cavity has a downwardly inclined annular scraping part, the end of which abuts against the outer wall of the straw. The lower opening of the receiving cavity has an outwardly extending snap-fit ​​part that abuts against the lower end face of the mouth of the outer bottle.

[0006] The straw has an outwardly extending extension on its outer wall, and an upwardly extending fitting part on the edge of the extension. The fitting part abuts against the upper end face of the screw joint. The upper end face of the screw joint has a downward-opening fitting groove that mates with the fitting part.

[0007] It also includes a sealing ring, which fits onto the outer wall of the straw and abuts against the lower end of the extension, with the lower end of the sealing ring abutting against the upper opening of the receiving cavity.

[0008] This dropper-roller press bottle features an outer bottle for holding liquid cosmetics. To draw the liquid into the straw, a flexible tip is located at the top. Pressing the flexible tip creates a vacuum in the straw's storage chamber. Releasing the flexible tip draws the liquid into the storage chamber from the bottom of the straw. To allow the rolling ball to carry the liquid out and apply it to the skin, a circular groove connecting the storage chamber is located at the bottom of the straw. The rolling ball is embedded in this groove, with its diameter slightly smaller than the groove's diameter, allowing it to roll and continuously draw the liquid out of the storage chamber for application. The rolling ball ensures even and stable liquid delivery, preventing waste from excessive liquid squeezing out and allowing for precise and uniform application. To replenish the storage chamber, similar to using a regular straw, insert the straw into the outer bottle and press the flexible tip to draw the liquid into the storage chamber through the gap between the rolling ball and the groove.

[0009] The outer bottle has an opening diameter of 13-23mm, which can accommodate the insertion of a straw and ensures that the storage cavity inside the straw has sufficient space to hold the liquid, maintaining a suitable capacity. Since the straw is inserted into the outer bottle to absorb liquid and then removed for use, and the outer bottle needs to be transported or carried, it is easy to spill if not sealed. Therefore, a sealing element is installed at the bottle opening. The sealing element is nested at the bottle opening and has a receiving cavity for the straw to pass through. A downward-sloping annular scraper is set in the receiving cavity. Therefore, when the straw is pulled upward in the outer bottle, the liquid absorbed on the straw can be scraped off as it passes through the scraper, preventing the outer wall of the straw from being sticky and constantly dripping liquid during use. The elastic material of the sealing element can effectively deform, so that the straw remains in a soft connection state during insertion or removal, reducing resistance.

[0010] There are two structural forms of the seal. One is that its upper end extends outward and downward, completely covering the bottle mouth. At its downward extension, there is also a raised ring that is inserted into the groove of the bottle mouth for locking and fixing. The lower end of the seal extends outward into the outer bottle and gradually narrows to form a ring-shaped scraper that abuts against the outer wall of the straw. The other is that its upper end extends slightly outward to form a limiting part, and its lower end also extends outward to form a snap-fit ​​part. It is fitted into the bottle mouth of the outer bottle in a nested manner, and the scraper is set in the receiving cavity inside.

[0011] To facilitate securing the straw, an outer cap is provided. The outer cap is screwed onto the external thread at the bottle opening via an internal screw-in part, thus securing the outer cap to the bottle. The flexible straw tip is located on the through hole, so when the outer cap is unscrewed and moved upwards, the straw connected to the lower end of the flexible straw tip is lifted along with it. The outer cap is also designed for easy handling. Since the upper end of the straw is embedded in the flexible straw tip, in actual use, because the storage chamber also contains liquid, the weight of the straw can easily cause it to fall off the flexible straw tip during use. Therefore, an extension and a fitting part are provided on the straw. During the assembly of the flexible straw tip, the fitting part is inserted into the fitting groove on the upper end face of the screw-in part to secure it, ensuring a stable connection of the straw.

[0012] Although the scraper can prevent the liquid inside the outer bottle from overflowing from the receiving cavity, the seal is made of elastic material, so it is inevitable that it will overflow from the deformation of its gaps during carrying. Therefore, a sealing ring is fitted on the straw at the lower end of the extension. When the outer cap is screwed into the outer bottle, the sealing ring gradually seals the upper opening of the receiving cavity, thereby achieving a double seal and preventing the liquid from leaking out.

[0013] Furthermore, it also includes a pressing assembly, which includes a pressing seat and a pressing head. The pressing seat is nested on the outer side wall of the outer cover, and the upper end face of the pressing seat is provided with a pressing hole. The outer side wall of the pressing head is fitted on the inner side wall of the pressing seat, and the pressing part at the upper end of the pressing head passes through the pressing hole and extends out of the pressing seat.

[0014] Compared with the prior art, the advantages of this utility model are as follows: By setting a circular groove at the lower end of the straw for the ball bearing to be inserted, the rolling of the ball bearing can achieve uniform and stable liquid delivery, avoiding waste caused by excessive liquid squeezing out, and enabling quantitative and uniform application. The design of the scraping part can scrape off the liquid adsorbed on the straw when it is pulled upward in the outer bottle, avoiding the sticky outer wall of the straw and the continuous dripping of liquid during use. The two types of sealing elements can be fitted at the bottle mouth, and can be selected for different situations. The sealing ring can achieve double sealing in the receiving cavity to prevent liquid leakage. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The specific embodiments of this utility model will now be described with reference to the accompanying drawings: Example 1, such as Figure 1-5 As shown, a dropper-ball press bottle includes an elastic suction head 1, a straw 2, a ball 3, an outer bottle 4, and an outer cap 6. The straw 2 is a tubular structure extending vertically, with a storage cavity 21 inside. The lower end of the straw 2 has a circular groove 22 communicating with the storage cavity 21. The elastic suction head 1 is detachably connected to the upper opening of the straw 2. The ball 3 is embedded in and rotatably connected to the circular groove 22. The straw 2 extends from top to bottom into the outer bottle 4. The diameter of the bottle opening of the outer bottle 4 is 13-23 mm. The inner cavity of the outer cap 6 has a downwardly extending tubular screw-in part 61. The inner side wall of the screw-in part 61 has an internal thread 62. The outer side wall of the bottle opening of the outer bottle 4 has an external thread 41 that mates with the internal thread 62. The upper end face of the screw-in part 61 has a through hole 63 penetrating the outer cap 6. The elastic suction head 1 is detachably connected to the through hole 63.

[0020] It also includes a sealing element 5, which is made of elastic material. The sealing element 5 is nested at the mouth of the outer bottle 4. The center of the sealing element 5 is provided with a receiving cavity 51 through which the straw 2 passes. The receiving cavity 51 is provided with a downwardly inclined annular scraping part 52. The end of the scraping part 52 abuts against the outer side wall of the straw 2. The lower opening of the receiving cavity 51 is provided with an outwardly extending snap-fit ​​part 53, which abuts against the lower end face of the mouth of the outer bottle 4.

[0021] The outer wall of the straw 2 is provided with an outwardly extending extension 23, and the edge of the extension 23 is provided with an upwardly extending fitting part 24, which abuts against the upper end surface of the screwing part 61; the upper end surface of the screwing part 61 is provided with a downwardly opening fitting groove 64, which cooperates with the fitting part 24.

[0022] It also includes a sealing ring 7, which fits onto the outer wall of the straw 2 and abuts against the lower end of the extension 23, with the lower end of the sealing ring 7 abutting against the upper opening of the receiving cavity 51.

[0023] Description of the working principle of this utility model: The dropper bottle with this structure has an outer bottle 4 for holding liquid cosmetics. To allow the liquid to be drawn into the straw 2, an elastic suction head 1 is provided at the upper end of the straw 2. Pressing the elastic suction head 1 creates a vacuum negative pressure in the storage cavity 21 inside the straw 2. Releasing the elastic suction head 1 allows the liquid to be drawn into the storage cavity 21 from the lower end of the straw 2. To allow the liquid to be carried out and applied to the body by the rolling ball 3 at the end of the straw 2, a circular groove 22 connecting to the storage cavity 21 is provided at the lower end of the straw 2. The rolling ball 3 is embedded in the circular groove 22. The diameter of bead 3 is slightly smaller than the diameter of the circular groove 22, so bead 3 can roll inside the circular groove 22. The rolling of bead 3 continuously carries out the liquid in the storage chamber 21, thereby achieving application on the human body. The rolling of bead 3 can achieve uniform and stable liquid delivery, avoiding waste caused by excessive liquid squeezing out. It can achieve quantitative and uniform application. When it is necessary to replenish the liquid in the storage chamber 21, just like sucking liquid with a regular straw 2, insert straw 2 into the outer bottle 4 and press the elastic suction head 1 to suck the liquid into the storage chamber 21 from the gap between bead 3 and circular groove 22.

[0024] The outer bottle 4 has a bottle opening diameter of 13-23mm, which can accommodate the insertion of the straw 2. This ensures that the storage cavity 21 inside the straw 2 has sufficient space to hold the liquid and maintain a suitable capacity. Since the straw 2 is inserted into the outer bottle 4 to absorb liquid and is then removed for use, and the outer bottle 4 needs to be transported or carried, it is easy to spill if it is not sealed. Therefore, a sealing element 5 is provided at the bottle opening. The sealing element 5 is nested at the bottle opening and has a receiving cavity 51 through which the straw 2 passes. A downwardly inclined annular scraping part 52 is provided in the receiving cavity 51. Therefore, when the straw 2 is pulled upward in the outer bottle 4, the liquid absorbed on the straw 2 can be scraped off as it passes through the scraping part 52, preventing the outer wall of the straw 2 from being sticky and constantly dripping liquid during use. The elastic material of the sealing element 5 can effectively deform, so that the straw 2 is always in a soft connection state during insertion or removal, reducing resistance.

[0025] The sealing element 5 has two structural forms. One is that its upper end extends outward and downward to completely cover the bottle mouth. A protruding ring is provided at its downward extension. The protruding ring is inserted into the groove of the bottle mouth for locking and fixing. The lower end of the sealing element 5 extends into the outer bottle 4 and gradually narrows to form a ring-shaped scraping part 52, which abuts against the outer wall of the straw 2. The other is that its upper end extends slightly outward to form a limiting part, and its lower end also extends outward to form a snap-fit ​​part 53. It is fitted into the bottle mouth of the outer bottle 4 in a nested manner, and the scraping part 52 is set in the receiving cavity 51 inside it.

[0026] To facilitate securing the straw 2, an outer cover 6 is provided. The outer cover 6 is screwed onto the external thread 41 at the mouth of the outer bottle 4 via its internal screw-in part 61, thus securing the outer cover 6 and the outer bottle 4. The elastic suction head 1 is located on the through hole 63. Therefore, when the outer cover 6 is unscrewed and moved upwards, the straw 2 connected to the lower end of the elastic suction head 1 will be lifted together. The outer cover 6 is also convenient for hand handling. Since the upper end of the straw 2 is embedded in the elastic suction head 1, and liquid is also present in the storage cavity 21 during actual use, the weight of the straw 2 can easily cause it to fall off the elastic suction head 1. Therefore, an extension part 23 and a fitting part 24 are provided on the straw 2. During the assembly of the elastic suction head 1, the fitting part 24 is embedded into the fitting groove 64 on the upper end face of the screw-in part 61 to secure it, ensuring a stable connection of the straw 2.

[0027] Although the scraper 52 can prevent the liquid in the outer bottle 4 from overflowing from the receiving cavity 51, since the seal 5 is made of elastic material, it is inevitable that it will overflow from the deformation of its gaps during the carrying process. Therefore, a sealing ring 7 is fitted on the straw 2 at the lower end of the extension 23. When the outer cap 6 is screwed into the outer bottle 4, the sealing ring 7 gradually seals the upper opening of the receiving cavity 51, thereby achieving a double seal and preventing the liquid from leaking out.

[0028] Example 2, as Figure 6-10 As shown, it also includes a pressing assembly 8, which includes a pressing seat 81 and a pressing head 82. The pressing seat 81 is nested on the outer side wall of the outer cover 6. The upper end face of the pressing seat 81 is provided with a pressing hole 83. The outer side wall of the pressing head 82 is fitted on the inner side wall of the pressing seat 81. The pressing part 84 at the upper end of the pressing head 82 passes through the pressing hole 83 and extends out of the pressing seat 81.

[0029] Pressing the elastic suction head 1 causes it to deform, thus drawing liquid into the straw 2. Alternatively, a pressing assembly 8 can be provided on the outer cover 6, in which a pressing seat 81 is nested on the outer wall of the outer cover 6, and the outer wall of the pressing head 82 is fitted on the inner wall of the pressing seat 81. These two locations need to be sealed to ensure that the space enclosed by the pressing head 82, the pressing seat 81, the outer cover 6, and the elastic suction head 1 is relatively sealed. Therefore, when pressing the pressing head 82 downward, the elastic suction head 1 can be compressed during the air compression process, causing it to deform. To facilitate pressing, a pressing part 84 extending from the pressing hole 83 is provided at the upper end of the pressing head 82, making it convenient to apply downward force from the outside.

[0030] The beneficial effects of this utility model are as follows: By setting a circular groove 22 at the lower end of the straw 2 for the ball bearing 3 to be embedded, the rolling of the ball bearing 3 can achieve uniform and stable liquid delivery, avoiding waste caused by excessive liquid squeezing out, and achieving quantitative and uniform application. The setting of the scraping part 52 can scrape off the liquid adsorbed on the straw 2 when the straw 2 is pulled upward in the outer bottle 4, avoiding the sticky outer wall of the straw 2 and the continuous dripping of liquid during use. The two types of sealing parts 5 can be fitted at the bottle mouth, and can be selected for use in different situations. The sealing ring 7 can achieve double sealing at the receiving cavity 51 to prevent liquid leakage.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
