Description

Technical Field

[0001] This application relates to the technical field of cosmetic containers, and particularly to a hidden pump head and a cosmetic container. Background Art

[0002] Liquid cosmetics are usually contained in spray bottles or atomizer bottles. When in use, by pressing the pump at the cap position of the spray bottle or atomizer bottle, the liquid is drawn from the bottle by the pump and then ejected from the nozzle for use.

[0003] Since the pressing end of the pump of a conventional spray bottle or atomizer bottle is located outside and can be directly pressed, when placed in a bag, it is easy to be accidentally touched, causing the liquid in the bottle to spray out and polluting the environment inside the bag, which is not conducive to carrying when going out.

[0004] At the same time, in families with children, spray bottles and atomizer bottles placed indoors are also likely to be used as toys by children, resulting in waste of cosmetics, and the ejected liquid may also cause harm to children. Summary of the Invention

[0005] In order to solve the problem that the pump of a traditional spray bottle or atomizer bottle is exposed outside and is easily accidentally touched, this application provides a hidden pump head and a cosmetic container.

The base is arranged vertically. The lifting seat is rotatably installed on the base in a vertical direction by a screw. The pressing pump is arranged on the lifting seat. The protective shell is rotatably installed on the base. The protective shell and the lifting seat are slidably connected in a vertical direction. When the lifting seat is at the bottom of the base, the pressing pump is located inside the protective shell. When the lifting seat rotates to the top of the base, the pressing pump extends out of the protective shell. The base is provided with a locking member for preventing the lifting seat from reversing when the lifting seat rotates to the upper end of the base. The outer bottle is connected to the base, the inner bottle is connected to the lifting seat, and the feeding end of the pressing pump passes through the lifting seat and is located in the inner bottle.

[0007] Through the above technical solution, when not in use, rotate the protective shell to drive the lifting seat to move to the lower end of the base, so that the pressing pump is located inside the protective shell, making it not easy to be accidentally pressed. When in need of use, rotate the protective shell, and through the protective shell, push the lifting seat and the pressing pump to rotate and extend out. After locking the lifting seat with the locking member, the pressing pump can be used to draw the liquid in the inner bottle. The overall structure is relatively simple, easy to use, and has a very low learning cost.

Detailed implementation manners

[0025] The following further elaborates on this application Figures 1-5 in further detail with reference to the appended drawings.

[0026] In a first aspect, an embodiment of the present application discloses a concealed pump head. Referring to Figure 1 、 Figure 2 and Figure 3 , it includes a square fixing seat 6, a square base 1, and a square protective shell 4.

[0027] Referring to Figure 1 、 Figure 2 and Figure 3 , the fixing seat 6 is used for fixedly inserting into an outer bottle. The base 1 is coaxially and rotatably mounted on the fixing seat 6, and the protective shell 4 is coaxially and rotatably mounted on the base 1. The base 1 can be rotated until its side wall is flush with the side wall of the fixing seat 6, and the protective shell 4 can be rotated until its side wall is flush with the side wall of the base 1.

[0028] Referring to Figure 2 and Figure 3 , the base 1 includes a square connecting plate 11 and a circular mounting cylinder 12 coaxially and integrally provided on the connecting plate 11. The inner hole of the mounting cylinder 12 penetrates through the connecting plate 11. A helical chute 121 is formed on the inner wall of the mounting cylinder 12. A lifting seat 2 is slidably mounted in the mounting cylinder 12 in a matching manner. A pressing pump 3 is coaxially and fixedly mounted in the lifting seat 2. The inner bottle is threadedly mounted on the lifting seat 2. The feeding end of the pressing pump 3 passes through the lifting seat 2 and is located in the inner bottle. The liquid in the inner bottle is pumped and ejected by pressing the pressing pump 3.

[0029] Referring to Figure 2 and Figure 3, there are two sliding grooves 121, and the two sliding grooves 121 are axially symmetrically distributed with the axis of the base 1 as the center. The sliding grooves 121 penetrate through the side wall of the mounting cylinder 12. A slider 13 is slidably mounted in the sliding groove 121. One end of the slider 13 is integrally connected to the lifting seat 2, and the other end of the slider 13 passes through the sliding groove 121 and is slidably connected to the protective shell 4.

[0030] Refer to Figure 2 and Figure 3 , place the base 1 and the mounting cylinder 12 vertically. The sliding connection between the slider 13 and the protective shell 4 is vertical, and the axis of the sliding groove 121 is vertical, so that by rotating the protective shell 4, the slider 13 and the lifting seat 2 can be driven to rotate up or down.

[0031] A through outlet is coaxially opened on the top wall of the protective shell 4. When the lifting seat 2 rises, the pressing cover of the pressing pump 3 is pressed out from the through outlet.

[0032] When the slider 13 is located at the bottom of the sliding groove 121, the pressing pump 3 is located in the protective shell 4, and the top wall of the pressing pump 3 is flush with the top wall of the protective shell 4.

[0033] Refer to Figure 2 and Figure 3 , a first locking groove 14 is opened on the side wall of the mounting cylinder 12 at the upper end of the sliding groove 121. The first locking groove 14 is horizontal and is connected to the sliding groove 121.

[0034] Both the first locking groove 14 and the second locking groove 15 are slidably matched with the slider 13. In the initial state, the side wall of the protective shell 4 is flush with the side wall of the connecting plate 11. At this time, the sliding groove 121 is located in the second locking groove 15. When the protective shell 4 rotates from the initial state to its side wall is flush with the side wall of the connecting plate 11 again, the slider 13 is located in the first locking groove 14, and the vertical displacement of the slider 13 is restricted by the locking groove.

[0035] At the same time, two locking members 5 are provided on the mounting cylinder 12, and the two locking members 5 are respectively located at the two sliding grooves 121. When the slider 13 is located in the first locking groove 14, the locking member 5 is used to limit the slider 13 from sliding back into the sliding groove 121.

[0036] Refer to Figure 2 and Figure 3 , the locking member 5 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 is made of plastic. The first clamping block 51 is located at the entrance end of the first locking groove 14 and is integrally connected to the side wall of the mounting cylinder 12.

[0037] The second clamping block 52 is made of plastic. The second clamping block 52 is opposite to the first clamping block 51 and is also integrally connected to the side wall of the mounting cylinder 12.

[0038] The first locking groove 14 penetrates through the top wall of the mounting cylinder 12, and the two second clamping blocks 52 respectively form the side walls on one side where the first locking groove 14 penetrates through the top wall of the mounting cylinder 12.

[0039] The slider 13 is circular. When the slider 13 slides to the entrance end of the first locking groove 14, by continuing to rotate the protective shell 4, the protective shell 4 drives the slider 13 to continue sliding towards the first locking groove 14. The slider 13 pushes the second clamping block 52 to deform and bend upwards to widen the sliding width of the first locking groove 14 at the first clamping block 51, so that the slider 13 can slide into the first locking groove 14.

[0040] Refer to Figure 2 and Figure 3 When the slider 13 slides into the first locking groove 14, the second clamping block 52 rebounds to its original position. At this time, the side wall of the slider 13 fits and abuts against one end side wall of the first locking groove 14, and the first clamping block 51 abuts against the side wall of the slider 13. The cooperation between the first clamping block 51 and the second clamping block 52 restricts the slider 13 from sliding out of the first locking groove 14, so that when using the pressing pump 3, the protective shell 4 is not prone to rotation, resulting in the failure of using the pressing pump 3.

[0041] And when the slider 13 enters the first locking groove 14, the side wall of the protective shell 4 is flush with the side wall of the connecting plate 11.

[0042] A second locking groove 15 is formed in the side wall of the mounting cylinder 12 at the lower end of the chute 121. The second locking groove 15 is horizontal and is connected to the chute 121.

[0043] Refer to Figure 2 and Figure 3 At the entrance ends of the two second locking grooves 15, a third clamping block 17 is provided respectively. Two avoidance grooves 16 are formed in the side wall of the mounting cylinder 12, and the two avoidance grooves 16 are respectively connected to the two second locking grooves 15. One ends of the two third clamping blocks 17 are integrally connected to the side walls of the two second locking grooves 15 respectively.

[0044] The third clamping block 17 reduces the sliding width of the second locking groove 15, and the third clamping block 17 can bend into the avoidance groove 16 under the action of an external force, so that the sliding width of the second locking groove 15 is restored.

[0045] When the slider 13 slides to the second locking groove 15, continue to rotate the protective shell 4. The protective shell 4 drives the slider 13 to continue sliding. After the slider 13 pushes the third clamping block 17 into the avoidance groove 16, it smoothly slides into the second locking groove 15. When the slider 13 slides until its side wall fits and abuts against one end side wall of the second locking groove 15, the third clamping block 17 resumes its position and abuts against the side wall of the slider 13, restricting the sliding of the slider 13. This ensures that when the pressing pump 3 is retracted, the protective shell 4 is not prone to rotation. When it is placed together with other objects during daily carrying, the protective shell 4 is not likely to rotate due to collision with other objects, causing the pressing pump 3 to extend and resulting in accidental pressing of the pressing pump 3 to discharge liquid and cause contamination.

[0046] Refer to Figure 2 and Figure 3 , a limiting block 171 is integrally provided on the side of the third clamping block 17 facing away from the second locking groove 15. When the slider 13 slides to the third clamping block 17, the slider 13 pushes the third clamping block 17 into the avoidance groove 16, and the limiting block 171 abuts against the side wall of the avoidance groove 16, preventing the third clamping block 17 from being overly bent and causing cracks at the connection with the side wall of the mounting cylinder 12.

[0047] Refer to Figure 2 and Figure 3 , a nozzle 31 is integrally provided on the side wall of the pressing cover of the pressing pump 3. The liquid extracted by the pressing pump 3 is ejected from the nozzle 31, so that when the pressing pump 3 ejects liquid, the liquid is not likely to remain on the side wall of the pressing cover of the pressing pump 3.

[0048] A receiving groove 42 is formed on the top wall of the protective shell 4. The area of the receiving groove 42 is larger than the area of its bottom. When the pressing pump 3 is retracted into the protective shell 4, the nozzle 31 is fitted and embedded in the receiving groove 42, and the bottom wall of the nozzle 31 fits against the bottom of the receiving groove 42.

[0049] Through the above design, when the nozzle 31 and the pressing pump 3 are in the retracted state, when pressing the pressing pump 3, due to the blocking of the nozzle 31, the pressing pump 3 cannot be pressed down, so that the pressing pump 3 cannot be pressed to discharge liquid in the retracted state, and the pressing pump 3 will not still be able to be pressed to discharge liquid after being retracted.

[0050] Refer to Figure 2 , Figure 4 and Figure 5 , the fixing base 6 is provided with two first fixing holes 61 and two second fixing holes 62. The first fixing holes 61 and the second fixing holes 62 are respectively located at the four top corners of the fixing base 6, and the first fixing holes 61 and the second fixing holes 62 are arranged alternately.

[0051] Refer to Figure 2 and Figure 5, the depth of the first fixing hole 61 is greater than that of the second fixing hole 62, and magnets 71 are fixedly installed at the bottoms of both the first fixing hole 61 and the second fixing hole 62.

[0052] A vertical fixing pin 7 is slidably installed at one of the top corners of the connecting plate 11, and the fixing pin 7 is slidably engaged with both the first fixing hole 61 and the second fixing hole 62.

[0053] The fixing pin 7 is made of magnetic metal. In the initial state when the connecting plate 11 is flush with the side wall of the fixing base 6, the lower end of the fixing pin 7 is slidably inserted into the first fixing hole 61, and the lower end of the fixing pin 7 is attached and adsorbed to the magnet 71.

[0054] The fixing pin 7 is fixed in the first fixing hole 61 by the magnet 71, thereby forming a fixation between the fixing base 6 and the connecting plate 11.

[0055] Refer to Figure 2 and Figure 5 , a third fixing hole 41 is formed in the bottom wall of the protective shell 4, and the third fixing hole 41 is slidably engaged with the fixing pin 7. When the protective shell 4 rotates until the slider 13 is located in the second locking groove 15, the third fixing hole 41 is aligned with the fixing pin 7, and the connecting plate 11 is provided with a pushing mechanism 8 for pulling out the fixing pin 7 from the first fixing hole 61.

[0056] During normal use, it is only necessary to keep the fixing pin 7 inserted into the first fixing hole 61. When it is necessary to prevent children from playing with it as a toy and the sprayed cosmetics may cause harm to children, first pull out the fixing pin 7 from the first fixing hole 61 through the pushing mechanism 8. At this time, the upper end of the fixing pin 7 is slidably inserted into the third fixing hole 41, the connection between the connecting plate 11 and the fixing base 6 is unlocked, and a fixation is formed between the connecting plate 11 and the protective shell 4.

[0057] Rotate the protective shell 4 and the connecting plate 11 until the connecting plate 11 is misaligned with the fixing base 6, then release the pushing mechanism 8, and continue to rotate the protective shell 4 until the side walls of the protective shell 4 and the connecting plate 11 are flush with the side wall of the fixing base 6 again. At this time, under the action of gravity, the lower end of the fixing pin 7 is slidably inserted into the second fixing hole 62 and is attached and adsorbed to the magnet 71 in the second fixing hole 62 to form a fixation. At the same time, the upper end of the fixing pin 7 is still located in the third fixing hole 41. The fixing base 6, the connecting plate 11 and the protective shell 4 are fixed by the fixing pin 7, and the protective shell 4 is locked to prevent children from playing with the cosmetics as a toy and causing harm to themselves when playing.

[0058] Refer to Figure 2 and Figure 5, the pushing mechanism 8 includes a push rod 81 and a push block 82. One of the corner side walls of the connecting plate 11 is provided with a mounting hole 111, and the push rod 81 is slidably mounted in the mounting hole 111. The push block 82 is integrally provided on the side wall of the fixing pin 7. The installation space of the fixing pin 7 communicates with the mounting hole 111, and one end of the push block 82 extends into the mounting hole 111.

[0059] On the opposite surfaces of the push rod 81 and the push block 82, a first guiding surface 811 and a second guiding surface 821 are respectively provided. Both the first guiding surface 811 and the second guiding surface 821 are inclined surfaces and are mutually attached. When the fixing pin 7 is inserted into the first fixing hole 61, the push rod 81 is pushed towards the inside of the mounting hole 111, so that one end of the push block 82 slides along the first guiding surface 811, thereby driving the push block 82 to rise and pulling out the fixing pin 7 from the first fixing hole 61. The process of pulling out the fixing pin 7 from the second fixing hole 62 is the same as the above process.

[0060] Refer to Figure 2 and Figure 5 , a spring 83 is sleeved on the push rod 81. One end of the spring 83 abuts against the side wall of the connecting plate 11. The push rod 81 is integrally provided with a retaining ring, and the other end of the spring 83 abuts against the retaining ring. The spring 83 is used to reset the push rod 81. A protective cover 18 is inserted into the connecting plate 11. One end of the push rod 81 is located in the protective cover 18. By blocking the push rod 81 with the protective cover 18, the push rod 81 is not easily accidentally touched during daily use.

[0061] When the protective cover 18 is installed on the connecting plate 11, an integral body is formed between the protective cover 18 and the connecting plate 11. One end of the protective cover 18 is provided with a groove 181 for lifting the protective cover 18.

[0062] In the second aspect, refer to Figure 1 and Figure 2 , this embodiment discloses a cosmetic container, including: A protective bottle 9 with a rectangular bottle mouth; A solution bottle 10, which is arranged inside the protective bottle 9 and is connected to the lifting seat 2 described above; The bottle mouth of the protective bottle 9 is inserted and fixed in the above-mentioned fixing seat 6.

[0063] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
