Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a controllable quantity paste container that is not easily contaminated. Background Technology

[0002] Current balm container products, such as lipstick jars, mostly employ a rotating design that moves the contents upwards to expose the balm at the bottle opening for easy use. However, direct use with the entire contents exposed at the bottle opening can easily contaminate unused contents; moreover, the amount used is based solely on personal feeling, making it difficult to control the amount used. This application addresses these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a controllable quantity paste container that is not easily contaminated, in order to solve the problems of easy contamination and inability to control the quantity of existing paste containers.

[0004] To address the aforementioned problems, this utility model provides a controllable quantity ointment container that is not easily contaminated, comprising an upper cap, an inner cap, a bottle body, a piston, a screw, a screw sleeve, and a bottom cap. The inner cap has an extrusion hole and is fastened to the bottle body and connected to the screw sleeve. The inner cap and the screw sleeve can rotate synchronously. The piston is installed in the bottle body, and the bottle body, inner cap, and piston form a receiving cavity for containing the contents. The screw is connected to the piston and threadedly connected to the screw sleeve. When the screw sleeve is rotated, the screw can generate axial displacement, driving the piston to discharge the contents through the extrusion hole. The bottom cap is installed outside the screw sleeve, and the upper cap can be fastened to the outside of the inner cap and connected to the bottom cap. The screw sleeve has several positioning notches on its outer side, and the bottom cap has several positioning ribs on its inner wall. The positioning ribs can extend into the positioning notches, and the bottom cap and the screw sleeve can rotate relative to each other. When the positioning ribs move from one positioning notch to another, a tactile sensation and sound are generated to indicate to the user that the measured amount has been reached.

[0005] The bottom cover, the screw, the bottle body, and the piston are locked together by fastening or limiting, preventing relative rotation; the inner cover and the screw sleeve are also locked together, preventing relative rotation.

[0006] The rotation of the inner cover causes the vertical wall of the inner top surface of the inner cover to scrape off the contents of the ointment, which are then extruded through the elongated hole onto the outer top surface of the inner cover. The user can directly use the extruded ointment without having to touch the ointment in the container cavity, thus reducing the probability of contamination.

[0007] As shown in the figure, a well-sealed cavity C is formed between the bottle body, the inner cap, and the piston, and the contents of the ointment in the cavity C are not easily contaminated.

[0008] According to one embodiment of the present invention, the bottom cover has a protrusion on its outer side, and the upper cover has a mating groove on its inner wall. When the upper cover is closed, the protrusion enters the mating groove to achieve a locking effect.

[0009] According to one embodiment of the present invention, the outer surface of the bottle body is provided with an annular rib, and the inner wall of the inner cap is provided with a limiting rib. The annular rib is used to cooperate with the limiting rib to prevent the inner cap from detaching from the bottle body.

[0010] According to one embodiment of the present invention, the bottle body is provided with an annular groove on the outside; the screw sleeve is provided with an annular rib II on the outside, and the annular groove is used to cooperate with the annular rib II to realize the joint installation of the bottle body and the screw sleeve.

[0011] According to one embodiment of the present invention, the inner wall of the inner cover is provided with a plurality of anti-rotation ribs I distributed in a ring, and the outer wall of the threaded sleeve is provided with a plurality of anti-rotation ribs II distributed in a ring. The anti-rotation ribs I and II cooperate to enable the threaded sleeve and the inner cover to rotate synchronously.

[0012] According to one embodiment of the present invention, the central part of the bottle body is provided with several vertical grooves, and the screw is provided with several guide ribs. The guide ribs can be inserted into the vertical grooves and can move along the vertical grooves, thereby guiding the movement of the screw.

[0013] According to one embodiment of the present utility model, four guide ribs are provided at the center of the bottom cover, and the upper end of the guide ribs can be inserted into the vertical groove so that the bottle body and the bottom cover cannot rotate relative to each other.

[0014] According to one embodiment of the present invention, the screw has several guide notches inside, and the guide ribs can be inserted into the guide notches so that the screw moves along the guide ribs when it moves.

[0015] According to one embodiment of the present invention, the extrusion orifice includes a plurality of elongated orifices, the lower end of which extends into the receiving cavity and is provided with a vertical wall for scraping off the contents of the paste.

[0016] According to one embodiment of the present invention, the outer top surface of the inner cover is provided with an indicator structure for indicating the direction of rotation. The indicator structure may be a printed indicator arrow or a raised indicator arrow structure.

[0017] The beneficial effects of this utility model are as follows: In this solution, a well-sealed receiving cavity is formed between the bottle body, inner cap, and piston, making the contents of the ointment within the receiving cavity less susceptible to contamination. Furthermore, during use, the ointment is squeezed out through the elongated hole onto the outer top surface of the inner cap, allowing the user to directly use the squeezed-out ointment without contacting the ointment within the receiving cavity, thus reducing the probability of contamination. During use, the bottom cap and screw sleeve rotate relative to each other. When the positioning rib moves from one positioning notch to another, a tactile sensation and sound are produced, indicating to the user that a measured amount has been used. This allows for precise control of the amount of ointment used, providing the user with greater convenience and comfort. Attached Figure Description

[0029] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0030] A non-contamination, controllable volume paste container, such as Figures 1-10 It includes an upper cover 1, an inner cover 2, a bottle body 3, a piston 4, a screw 5, a screw sleeve 6, and a bottom cover 7.

[0031] The inner cover 2 is provided with an extrusion hole, which includes an elongated hole 21 and an elongated hole 22. The lower end of the elongated hole extends into the receiving cavity and is provided with vertical walls 211 and 221 that can scrape off the contents of the paste. When the inner cover 2 rotates, the vertical walls can scrape the surface of the contents in the receiving cavity, assisting the contents to be discharged from the extrusion hole. The outer top surface of the inner cover 2 is provided with a rotation indicator arrow 25.

[0032] The bottle body 3 has an annular rib 31 on the outside, and the inner wall of the inner cap 2 has four limiting ribs 23. The annular rib 31 is used to cooperate with the limiting ribs 23 to restrict the inner cap 2 from detaching from the bottle body 3. The bottle body 3 and the inner cap 2 can rotate relative to each other.

[0033] The bottle body 3 has an annular groove 33 on its outside; the screw sleeve 6 has an annular rib 64 on its outside, and the annular groove 33 is used to cooperate with the annular rib 64.

[0034] The bottle body 3 has a vertical groove 32 at its center. Preferably, there are eight sets of vertical grooves 32. The screw 5 has four guide ribs 52 on its outside. The guide ribs 52 can be inserted into the vertical grooves 32 and can move along the vertical grooves 32, which can guide the movement of the screw 5. The bottom cover 7 has four guide vertical ribs 72 at its center. The upper end of the guide vertical ribs 72 can be inserted into the vertical grooves 32, so that the bottle body 3 and the bottom cover 7 cannot rotate relative to each other.

[0035] A receiving cavity C is formed between the bottle body 3, the inner cap 2, and the piston 4. The receiving cavity C is used to hold the contents of the paste.

[0036] The inner wall of the inner cover 2 is provided with a number of anti-rotation ribs 24 arranged in a ring, and the outer wall of the threaded sleeve 6 is provided with a number of anti-rotation ribs 61 arranged in a ring. The anti-rotation ribs 24 and the anti-rotation ribs 61 cooperate to enable the threaded sleeve 6 and the inner cover 2 to rotate synchronously.

[0037] Piston 4 is installed in the receiving cavity of bottle body 3. Piston 4 has a cylindrical part at its center and an annular rib 42 on the outside of the cylindrical part. The inner wall of the central hole of screw 5 has an annular rib 54. Piston 4 and screw 5 are fastened and fixed by annular ribs 42 and 54. When screw 5 moves upward, the top of screw 5 pushes piston 4 upward. When screw 5 moves downward, annular ribs 54 of screw 5 pull piston 4 downward synchronously.

[0038] The screw 5 has a threaded structure 51 on its outside. The screw 5 has a cylindrical structure, and four guide ribs 52 are set on the outer surface of the cylindrical structure and extend along the axial direction of the cylindrical structure.

[0039] The cylindrical structure of the screw 5 has four guide notches 53 inside, and the guide notches 53 and guide ribs 52 are staggered. The bottom cover 7 has four guide vertical ribs 72 at the center. The guide vertical ribs 72 can be inserted into the guide notches 53, so that the screw 5 moves along the guide vertical ribs 72 when it moves.

[0040] The center of the screw sleeve 6 is provided with a threaded hole 63, and the threaded structure 51 is used to engage with the threaded hole 63.

[0041] The outer side of the screw sleeve 6 is provided with four positioning notches 62, and the inner wall of the bottom cover 7 is provided with four positioning ribs 71. The positioning ribs 71 can extend into the positioning notches 62. The bottom cover 7 and the screw sleeve 6 can rotate relative to each other. When the positioning ribs 71 move from one positioning notch 62 to another positioning notch 62, a tactile sensation and sound will be generated to remind the user to achieve the effect of quantitative use.

[0042] The bottom cover 7 has a protrusion 73 on its exterior, and the upper cover 1 has a mating groove 11 on its inner wall. When the upper cover 1 is closed, the protrusion 73 enters the mating groove 11 to achieve a locking effect.

[0043] like Figure 1 As shown, this state indicates that the ointment container is stored or unused.

[0044] The bottle body 3 and the inner cap 2 are connected by an annular rib 31 and a limiting rib 23 to prevent the inner cap 2 from detaching from the bottle body 3, while the bottle body 3 and the inner cap 2 can rotate relative to each other.

[0045] The inner cover 2 and the screw sleeve 6 are connected by the outer anti-rotation rib 1 24 and the anti-rotation rib 2 61, so that the screw sleeve 6 and the inner cover 2 can rotate synchronously.

[0046] The screw 5 engages with the threaded sleeve 6, with the guide rib 52 engaging with the vertical groove 32, and with the guide notch 53 engaging with the guide vertical rib 72, thus guiding the movement of the screw 5.

[0047] The four vertical ribs 72 in the center of the bottom cover 7 can be inserted into the four guide notches 53 of the screw 5, and into the corresponding vertical grooves 34 on the central hole wall of the bottle body 3, thus achieving the connection effect between the bottom cover 7 and the bottle body 3.

[0048] The bottom cap 7, screw 5, bottle body 3, and piston 4 are connected by fastening or limiting, preventing relative rotation; the inner cap 2 and screw sleeve 6 are also connected by limiting, preventing relative rotation.

[0049] like Figure 10As shown, remove the top cover 1, hold the bottom cover 7, and rotate the inner cover 2 in the direction indicated by the rotation indicator arrow 25 on the top surface of the inner cover 2. The inner cover 2 drives the screw sleeve 6 to rotate synchronously. The screw sleeve 6 drives the screw 5 to move upward along the four vertical ribs 72 at the center of the bottom 7 through its threads, synchronously driving the piston 4 to move up and down in the receiving cavity C of the bottle body 3. The upward movement of the piston 4 causes the contents of the paste to move upward. The rotation of the inner cover 2 causes the vertical walls 211 and 221 on the inner top surface of the inner cover 2 to scrape away the contents of the paste, which are then squeezed out through the elongated holes 21 and 22 onto the outer top surface of the inner cover 2. The user can directly use the squeezed-out paste without touching the paste in the receiving cavity, reducing the probability of contamination.

[0050] As shown in the figure, a well-sealed cavity C is formed between the bottle body 3, the inner cap 2, and the piston 4, making the contents of the ointment in the cavity C less susceptible to contamination.

[0051] The annular groove 11 of the top cover 1 engages with the four protrusions 73 on the upper part of the bottom 7. The top cover 1 serves to isolate and protect, further preventing the interior from being contaminated.

[0052] When the screw sleeve 6 rotates, the bottom cover 7 and the screw sleeve 6 rotate relative to each other. When the positioning rib 71 moves from one positioning notch 62 to another positioning notch 62, it will produce a tactile sensation and sound, prompting the user to achieve the effect of quantitative use, and can more accurately control the amount of ointment contents used.

[0053] In this invention, the user can directly use the paste squeezed onto the outer top surface of the inner cap, avoiding contact with the contents of the paste in the container cavity and thus avoiding contamination; and the amount used is controllable, providing the user with good convenience and comfort.

[0054] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
