Description

Technical Field

[0001] The invention relates to the technical field of bottle caps, and in particular to a pump-type bottle cap that is convenient for transportation and use. Background Art

[0002] At present, the lotion bottles for daily chemical products commonly seen in the market, such as shampoo bottles, shower gel bottles, detergent bottles, etc., are mostly in the form of pump heads for the convenience of users. The contents in the bottle are pumped out by pressing the pump head, which is convenient to use.

[0003] When existing lotion bottles are shipped from manufacturers, they are wrapped with a layer of plastic film on the surface to prove that the product has not been opened. Due to the design of the pump head, a curved spout protrudes from the bottle cap for the lotion to flow out after squeezing. However, since the curved spout is exposed on the outside of the bottle cap and has a relatively small diameter, it is easy to be bumped during transportation and transfer. When a bump occurs, the curved spout is easily damaged, affecting the appearance and continued use. Summary of the invention

[0032] like Figure 1-Figure 13 As shown, a pump bottle cap convenient for transportation and use comprises a cap body 1 and a pressure cap 4. A liquid delivery tube 2 is inserted inside the cap body 1 for delivering lotion. A first spring 3 is nested on the outer wall of the liquid delivery tube 2. A pressure seat 8 nested on the outer wall of the liquid delivery tube 2 is arranged above the first spring 3. The pressure cap 4 is fixed to the top of the pressure seat 8 by a buckle. When the pressure cap 4 is pressed, the pressure seat 8 can be driven to move downward, thereby squeezing air into the bottle body. A fixed plate 5 is integrally formed on the top of the pressure cap 4. A retractable liquid discharge gun 6 is fixed by a buckle on the fixed plate 5. The upper end of the liquid delivery tube 2 is connected to the retractable liquid discharge gun 6 through a connecting hose 9. The retractable liquid discharge gun 6 comprises a liquid discharge tube 61 and a liquid inlet pipe joint 62 formed together at 90 degrees. The liquid discharge tube 61 and the liquid inlet pipe joint 62 are formed with a connection to The infusion channel 64 is convenient for the outflow of emulsion. A fixed column 63 is formed at the tail of the liquid outlet tube 61. A second spring 7 is nested on the outer wall of the fixed column 63. A movable wedge block 65 is inserted at the outer end of the fixed column 63. A wedge-shaped limiting column 17 that fits together with the movable wedge block 65 is formed inside the cover body 1. When the gland 4 moves downward, the movable wedge block 65 moves downward along the inclined surface of the wedge-shaped limiting column 17, which can push the retractable liquid outlet gun 6 to move horizontally, so that the liquid outlet tube 61 gradually extends to the outside of the gland 4. When the gland 4 is released, the first spring 3 drives the gland 4 back to its original position. At this time, the movable wedge block 65 is pushed to move horizontally in the opposite direction during the upward movement by the force of the second spring 7, thereby driving the liquid outlet tube 61 to retract into the gland 1.

[0033] In this embodiment, the cover body 1 includes a lower ring body 11 and an upper ring body 12 which are integrally formed. A threaded groove connected to the lotion bottle body is formed on the inner wall of the lower ring body 11, a fixing tube 14 is formed in the center of the lower ring body 11, and a circular ring rib 15 is formed inside the lower end of the fixing tube 14. An upper mounting groove 13 is formed in the center of the upper ring body 12, and a wedge-shaped limiting column 17 is formed on the edge of the upper mounting groove 13. A ventilation groove 16 is formed on the inner wall of one end of the fixing tube 14 close to the upper mounting groove 13. The upper mounting groove 13 is concentric with the cover body 1, and the diameter of the upper mounting groove 13 is larger than the inner diameter of the fixing tube 14.

[0034] In this embodiment, a straw connector 22 is formed at one end of the liquid delivery tube 2, and a hose connector 23 is formed at the other end of the liquid delivery tube 2. A fixing flange 21 is integrally formed on the outer wall of one end of the liquid delivery tube 2 close to the hose connector 23. The fixing flange 21 is installed in cooperation with the upper mounting groove 13. The fixing flange 21 is fixed by hot melt or detachably fixed in the upper mounting groove 13. Two arc-shaped limiting grooves 24 are symmetrically formed on the fixing flange 21, and the straw connector 22 passes through the center of the circular retaining edge 15.

[0035] In this embodiment, the gland 4 is slidably mounted in the upper ring body 12 , a mounting hole 41 is formed on the outer wall of the gland 4 , and the liquid outlet pipe 61 is inserted into the mounting hole 41 .

[0036] In this embodiment, a circular arc holder 52 is formed on the lower surface of the fixing plate 5 , and arc grooves 51 are symmetrically formed on both sides of the circular arc holder 52 . The circular arc holder 52 is buckled on the fixing column 63 , and the fixing column 63 can move laterally in the circular arc holder 52 .

[0037] In this embodiment, the pressure seat 8 includes a lower pressure ring 81, which is slidably mounted on the outer wall of the liquid delivery tube 2. The height of the lower pressure ring 81 is lower than the height of the air permeable groove 16. The inner diameter of the lower pressure ring 81 is the same as the outer diameter of the liquid delivery tube 2. The outer diameter of the lower pressure ring 81 is the same as the inner diameter of the fixed tube 14. The pressure seat 8 will close the space during the downward movement to reduce air loss and ensure that the pressure in the bottle body will gradually increase, thereby facilitating the pumping out of the lotion in the bottle body. Two arc-shaped connecting columns 82 are symmetrically formed on the upper surface of the lower pressure ring 81. The arc-shaped connecting columns 82 match the position and size of the limiting groove 24. The arc-shaped connecting columns 82 pass through the limiting groove 24 to ensure that the pressure seat 5 can move up and down normally. The arc-shaped connecting columns 82 are tightly fitted and inserted into the arc-shaped card groove 51.

[0038] The working principle of the present invention is as follows: when in use, the straw is installed on the straw joint 22 and then the cover body 1 is installed on the lotion bottle. Initially, the retractable liquid discharge gun 6 is retracted inside the pressure cover 4, and the pressure cover 4 is located at the uppermost end under the action of the first spring 3. At this time, the inner cavity of the upper ring body 12 is connected with the inner cavity of the fixed tube 14, and the air can be exchanged. When in use, the pressure cover 4 is pressed downward, and the pressure cover 4 drives the pressure seat 8 to move downward. The first spring 3 is compressed, and the lower pressure ring 81 moves downward to squeeze the air from the lower end of the fixed tube 14 into the lotion bottle, so that the lotion in the lotion bottle enters the straw and then enters the liquid delivery tube 2. After multiple presses, the air in the top of the lotion bottle increases, and the lotion is gradually squeezed out from the infusion channel 64 and then flows out. During the squeezing process, the movable wedge block 65 moves downward along the inclined surface of the wedge-shaped limiting column 17 and gradually moves horizontally. At this time, the second spring 7 is compressed, and the liquid outlet pipe 61 passes through the mounting hole 41 and extends to the outside of the gland 4. The farther the gland 4 moves downward, the longer the liquid outlet pipe 61 extends from the gland 4. When the pressure on the gland 4 becomes smaller, the first spring 3 rebounds to make the gland 4 move upward. At this time, the second spring 7 also gradually rebounds, so that the liquid outlet pipe 61 is retracted into the gland 4.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
