Description

Technical Field

[0001] The utility model belongs to the field of cosmetic containers, in particular to a rotary pump-type cosmetic bottle with the bottom being removable and replaceable. Background Art

[0002] At present, most cosmetic bottles adopt disposable or replaceable liner types. When the cream or other cosmetics in the cosmetic bottle are used up, if it is a disposable cosmetic bottle, the cosmetic bottle is usually discarded directly, which will cause packaging waste, especially the pump-type disposable cosmetic bottles. The cost of this type of cosmetic bottle will be higher, and for the replaceable liner type, due to the complex structure, most of them cannot achieve the combination of pump-type and replaceable. In the existing scheme of combining pump-type and replaceable, the pump cover is directly connected to the bottle body. Before switching the pressing state of the pump cover, it is necessary to hold the pump cover and the bottle body, and rotate them to the corresponding working position to complete pumping or limit to prevent accidental pumping. This method requires both hands to hold the bottle body and the irregular pump cover respectively, which is inconvenient to operate. In addition, cream residue is likely to remain on the pump cover, causing cream to be stained on the hands, which is inconvenient to operate. Summary of the Invention

[0003] The utility model aims to provide a screw-up pump-type cosmetic bottle with a bottom that can be taken out and replaced, which is more convenient for the operation of switching the state of the pump cover.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a screw-up pump-type cosmetic bottle that can be taken out and replaced at the bottom, which includes a bottle body, a bottle cap sleeved on the bottle body, a pump cap connected to the upper end of the bottle body, an inner liner penetrated into the bottle body and fixedly connected to the pump cap at the upper end, the pump cap includes a pump seat, a pump core provided on the pump seat, a guide rod extending along its radial direction is provided on the outer circumference of the pump seat, a first guide groove penetrating and extending obliquely is provided on the side wall of the bottle body, a second guide groove extending in a direction parallel to the axis of the bottle cap is provided on the inner side wall of the bottle cap, the guide rod is penetrated in the first guide groove and at least partially located in the second guide groove, The guide rod has a first working position and a second working position in the first guide groove, and the bottle cap is rotatably connected to the bottle body, and when the bottle cap rotates, the second guide groove pushes the guide rod to move in the first guide groove, thereby driving the pump cover to switch between the first working position and the second working position. When the guide rod is in the first working position, the upper end of the pump cover extends above the bottle cap, and the pump core will pump out the cream or cosmetic liquid in the cosmetic bottle after being pressed. When the bottle cap is rotated, the second guide groove pushes the guide rod to rotate downward along the first guide groove to the second working position, and the pump cover moves downward and is at least partially retracted into the bottle body and the bottle cap, and the liner at least partially extends out of the bottle body.

[0005] In another embodiment, an introduction groove connected to the first guide groove is opened on the side wall of the upper end of the bottle body, and when the pump cover is installed, the guide rod enters the first guide groove from the introduction groove.

[0006] In another embodiment, the first guide groove includes an oblique section extending spirally along the circumference of the bottle body, an upper transverse section and a lower transverse section extending along the circumference of the bottle body and along the circumference of the bottle body, the upper transverse section is connected to the upper end of the oblique section, and the lower transverse section is connected to the lower end of the oblique section. When the guide rod is in the upper transverse section, it is in a first working position, and when the guide rod is in the lower transverse section, it is in a second working position.

[0007] In another embodiment, a circumferentially extending limiting ring is provided on the circumferential surface of the upper end portion of the bottle body, and a circumferentially extending limiting groove is provided on the inner side wall of the lower end portion of the bottle cap. The limiting ring is clamped in the limiting groove, so that the bottle cap only has rotational freedom relative to the bottle body, while the freedom of axial movement relative to the bottle body and along the bottle body is limited.

[0008] In another embodiment, a fixing ring is formed on the inner side wall of the pump seat, a thread is provided in the fixing ring, and the inner liner is threadedly connected to the fixing ring.

[0009] In another embodiment, an annular limiting boss is formed on the inner wall of the bottle cap above the first guide groove. When the guide rod is in the first working state, the lower end of the limiting boss is pressed on the pump seat. When the guide rod is in the second working state, the upper end of the pump core is pressed on the limiting boss to prevent cream or cosmetic liquid from being pumped out when the pump core is pressed accidentally.

[0010] In another embodiment, when the first guide groove is in the second working position, the pump cover is completely retracted into the bottle body and the bottle cover, and the lower end of the inner liner extends out of the bottle body.

[0011] Due to the application of the above technical solution, the utility model has the following advantages compared with the existing technology: the state of the pump cover is switched by holding the bottle body and the bottle cap and rotating the two relative to each other, without directly holding the pump cover. The regular and annular bottle cap is easier to operate and can prevent the residual cream on the pump cover from sticking to the hands. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] like Figure 1-5 As shown, the bottom-removable and replaceable screw-up pump-type cosmetic bottle includes a bottle body 1, a bottle cap 2 that is sleeved on the bottle body 1 and is generally annular, a pump cover 3 connected to the upper end of the bottle body 1, an inner liner 4 that is passed through the bottle body 1 and the upper end of which is fixedly connected to the pump cover 3, and the pump cover 3 includes a pump seat 5 and a pump core 6 provided on the pump seat 5 (the pump core 6 is prior art, not the focus of the present utility model, and will not be described here).

[0019] A guide rod 7 extending radially thereof is provided on the outer circumferential surface of the pump base 5, a first guide groove 8 penetrating and extending obliquely is provided on the side wall of the bottle body 1, and a second guide groove 9 extending parallel to the axial direction of the bottle cap 2 is provided on the inner side wall of the bottle cap 2. The guide rod 7 is inserted into the first guide groove 8 and at least partially located in the second guide groove 9. The guide rod 7 has a first working position and a second working position in the first guide groove 8. The bottle cap 2 is rotatably connected to the bottle body 1, and when the bottle cap 2 rotates, the second guide groove 9 pushes the guide rod 7 to move in the first guide groove 8, thereby driving the pump cover 3 to switch between the first working position and the second working position. When the guide rod 7 is in the first working position, the upper end of the pump cover 3 extends above the bottle cap 2, and the pump core 6 will pump out the cosmetic liquid or cream in the cosmetic bottle when pressed. When the bottle cap 2 is rotated, the second guide groove 9 pushes the guide rod 7 to rotate downward along the first guide groove 8 to the second working position, the pump cover 3 moves downward and at least partially retracts into the bottle body 1 and the bottle cap 2, and the inner liner 4 at least partially extends out of the bottle body 1. In this embodiment, when the first guide groove 8 is in the second working position, the pump cover 3 is completely retracted into the bottle body 1 and the bottle cover 2 , and the lower end of the liner 4 extends out of the bottle body 1 .

[0020] An introduction groove 10 is formed on the side wall of the upper end of the bottle body 1 and is connected to the first guide groove 8. When the pump cover 3 is installed, the guide rod 7 enters the first guide groove 8 from the introduction groove 10. The first guide groove 8 includes an oblique section 11 extending spirally along the circumference of the bottle body 1, an upper transverse section 12 and a lower transverse section 13 extending along the circumference of the bottle body 1 and in the circumferential direction of the bottle body 1. The upper transverse section 12 is connected to the upper end of the oblique section 11, and the lower transverse section 13 is connected to the lower end of the oblique section 11. When the guide rod 7 is in the upper transverse section 12, it is in the first working position, as shown in FIG. Figure 1 As shown, the cosmetic bottle is in the unlocked state, that is, the guide rod 7 is in the first working position, at this time the button is pressed normally and the liquid is discharged normally; when the guide rod 7 is in the lower transverse section 13, it is in the second working position, as shown Figure 3 As shown, the cosmetic bottle is in a locked state, that is, the guide rod 7 is in the second working position, which can prevent the button from being accidentally touched to cause liquid to discharge, and the inner liner 4 can be replaced by holding the bottle body 1 and the inner liner 4 and rotating them.

[0021] A circumferentially extending retaining ring 14 is provided on the circumferential surface of the upper end of the bottle body 1. A circumferentially extending retaining groove 15 is provided on the inner sidewall of the lower end of the bottle cap 2. The retaining ring 14 is retained within the retaining groove 15, allowing the bottle cap 2 only rotational freedom relative to the bottle body 1, while limiting its axial freedom relative to and along the bottle body 1. A retaining ring 16 is formed on the inner sidewall of the pump base 5. The retaining ring 16 is threadedly connected to the inner liner 4. An annular retaining boss 17 is formed on the inner sidewall of the bottle cap 2 above the first guide groove 8. When the guide rod 7 is in the first operating position, the lower end of the retaining boss 17 presses against the pump base 5, further securing the connection between the pump base 5 and the bottle body 1. When the guide rod 7 is in the second operating position, the cosmetic bottle is locked, with the upper end of the pump core 6 pressing against the retaining boss 17, preventing accidental pumping of cream or lotion.
