Description

Technical Field

[0001] The utility model belongs to the field of cosmetic bottles, and in particular relates to a multi-layered bottle mouth cover structure without a shoulder sleeve. Background Art

[0002] With the rapid development of cosmetics, the competition in the cosmetics industry has become increasingly fierce. When people buy cosmetics, in addition to paying attention to the functions and effects of cosmetics, the bottles that hold cosmetics have also become a factor that affects people's purchases.

[0003] A cosmetic bottle usually includes a bottle body, a bottle cap and a pump body. Among them, the bottle cap needs to be convenient for users to open and close, and at the same time, it must ensure that the bottle can be tightly sealed to prevent product leakage or external contaminants from entering. The design of the bottle cap needs to be coordinated with the bottle body and the overall packaging style to enhance the overall aesthetics of the product. Existing cosmetic bottles can be provided with shoulder covers on the bottle body, so that the bottle cap, shoulder cover, and bottle body are made of different materials, colors, and textures to increase the layering and attractiveness of the cosmetic bottle, making it more personalized and fashionable, and increasing customers' desire to buy. However, the setting of the shoulder cover requires the configuration of corresponding fasteners and bayonet on the bottle body, and the production cost of the bottle body is high. The economic benefits of opening an additional mold just to improve the layering of the cosmetic bottle are poor. In addition, the existing vacuum pump cosmetic bottles are usually provided with a protective cover to prevent the vacuum pump from being damaged when the cosmetic bottle falls, causing the vacuum pump to fail, but most protective covers are single-layer protective covers, which have weak impact resistance, are easily damaged, and have a short service life.

[0004] Therefore, a shoulder-free multi-layer bottle mouth cover structure is urgently needed to solve the above problems. Summary of the invention

[0005] In response to the problems in the prior art, the utility model proposes a shoulder-less multi-layered bottle mouth cover structure. The protective cover composed of a protective outer cover and a protective inner cover improves the impact resistance of the protective cover, thereby increasing the service life of the protective cover; at the same time, the aesthetics of the cosmetic bottle is improved through the exposed abutment portion.

[0006] The utility model is implemented as follows: a shoulder-less multi-layer bottle mouth cover structure, comprising a pump head, the pump head is installed on the top of a cosmetic bottle, the cosmetic bottle comprises a bottle body, the top of the bottle body is provided with a bottle mouth, the pump head is clamped with the bottle mouth, the pump head comprises a vacuum pump body, a clamping cover inner cover and a clamping cover outer cover which are arranged in sequence from the inside to the outside, the clamping cover inner cover is clamped with the bottle mouth and presses the vacuum pump body against the bottle mouth; the clamping cover outer cover is clamped with the clamping cover inner cover;

[0007] It also includes a protective cover covering the pump head, the protective cover includes a protective outer cover and a protective inner cover made of the same material or different materials, the protective inner cover is sleeved on the inner wall of the protective outer cover; the bottom of the protective inner cover extends downward to the bottle shoulder, and extends outward along its circumference to form an abutment portion, the top of the abutment portion abuts against the lower edge of the card cover outer cover, and the outer peripheral surface of the abutment portion is exposed. The protective cover is formed by the card connection of the protective outer cover and the protective inner cover, and the outer peripheral surface of the abutment portion is exposed, so that the color and texture of the protective cover are richer, and the aesthetics of the cosmetic bottle is improved; at the same time, the protective cover forms a double-layer structure, which improves the impact resistance of the protective cover and prolongs the service life of the protective cover.

[0008] Preferably, the outer periphery of the protective inner cover is provided with a first flange and a first clamping groove arranged adjacent to each other in the upper and lower parts, and the inner wall of the protective outer cover is provided with a second clamping groove adapted to the first flange and a second flange adapted to the first clamping groove, and when the protective outer cover is clamped with the protective inner cover, the first flange and the second flange are clamped in the second clamping groove and the first clamping groove respectively. The protective outer cover and the protective inner cover are clamped with each other, which improves the clamping force between the two and makes the clamping between the protective outer cover and the protective inner cover more reliable.

[0009] Specifically, the top of the first flange is provided with a first transition portion that gradually decreases from bottom to top, and the bottom of the first flange is provided with a first blocking surface that is horizontally arranged. The first transition portion is used to reduce the resistance when the first flange is engaged with the second slot, making it easier for the first flange to be engaged with the second slot, thereby improving the convenience of the first flange when engaged. Since the first flange and the first slot are arranged adjacent to each other up and down, the bottom of the first flange forms a side wall of the first slot, and the first blocking surface is used to prevent the second flange from falling out of the first slot, thereby improving the reliability of the engagement between the two.

[0010] Preferably, the card cover outer cover is evenly provided with a plurality of arc-shaped anti-dropping bosses in the circumference, and the inner wall of the protective inner cover is provided with anti-dropping grooves adapted to the anti-dropping bosses. After the protective cover is installed, the anti-dropping bosses are snapped into the anti-dropping grooves. The anti-dropping bosses and the anti-dropping grooves increase the clamping force between the protective inner cover and the card cover outer cover, and are used to prevent the protective cover from being too loose, thereby causing the protective cover to fall off easily and be lost easily.

[0011] Preferably, the bottle mouth is provided with a third flange and a third slot adjacent to each other, and the card cover inner cover is provided with a fourth slot corresponding to the third flange and a fourth flange corresponding to the third slot. When the card cover inner cover is engaged with the bottle mouth, the third flange and the fourth flange are engaged with the fourth slot and the third slot respectively. The bottle mouth and the card cover inner cover are engaged with each other, which increases the engagement force between the two, makes it difficult for the card cover inner cover to be separated from the bottle mouth, and improves the installation reliability of the card cover inner cover.

[0012] Specifically, the top of the third flange is provided with a second transition portion that gradually decreases from bottom to top, and the bottom of the third flange is provided with a horizontally arranged second blocking surface. Since the third flange and the third clamping slot are arranged adjacent to each other in upper and lower directions, the bottom of the third flange forms a side wall of the third clamping slot, and the second blocking surface is used to prevent the fourth flange from escaping from the third clamping slot, thereby improving the reliability of the clamping connection between the inner cover of the clamping cap and the bottle mouth, thereby preventing the airtightness of the cosmetic bottle from being damaged, resulting in failure of the vacuum pump body and oxidation of the cosmetics.

[0013] Preferably, the bottle mouth is provided with a first anti-rotation part, the inner wall and outer periphery of the card cover inner cover are respectively provided with a second anti-rotation part and a third anti-rotation part, and the inner wall of the card cover outer cover is provided with a fourth anti-rotation part; when the card cover inner cover is engaged with the bottle mouth, the first anti-rotation part is plugged into the second anti-rotation part, and when the card cover outer cover is engaged with the card cover inner cover, the third anti-rotation part is plugged into the fourth anti-rotation part. The first anti-rotation part and the second anti-rotation part are used to prevent the card cover inner cover from rotating relative to the bottle mouth, thereby preventing the card connection between the two from being worn due to rotation, thereby destroying the airtightness of the cosmetic bottle; similarly, the third anti-rotation part and the fourth anti-rotation part are used to prevent the card cover inner cover and the card cover outer cover from rotating, further preventing the airtightness of the cosmetic bottle from being destroyed.

[0014] Preferably, the pump head further comprises a sealing gasket, which is sandwiched between the bottle mouth and the vacuum pump body. The sealing gasket is used to prevent a gap between the bottle mouth and the vacuum pump body, which would damage the airtightness of the cosmetic bottle, thereby further improving the airtightness of the cosmetic bottle.

[0015] Preferably, the protective outer cover is made of an opaque material, and the outer peripheral surface of the abutting portion is sprayed with a first decorative coating, which improves the aesthetics of the cosmetic bottle and enhances the consumer's experience.

[0016] As an equivalent alternative, the protective outer cover is made of a transparent material, and the outer surface of the protective inner cover is sprayed with a second decorative coating.

When the card cover inner cover 22 is clamped with the bottle mouth 11, the third flange 111 and the fourth flange 221 are respectively clamped in the fourth clamping groove 222 and the third clamping groove 112. The bottle mouth 11 and the card cover inner cover 22 are clamped with each other, which improves the clamping force between the two, makes it difficult for the card cover inner cover 22 to be separated from the bottle mouth 11, and improves the installation reliability of the card cover inner cover 22.

[0030] Specifically, a second transition portion 1111 which gradually decreases from bottom to top is provided on the top of the third flange 111, and a second blocking surface 1112 which is horizontally provided is provided on the bottom of the third flange 111. Since the third flange 111 and the third clamping groove 112 are disposed adjacent to each other up and down, the bottom of the third flange 111 forms a side wall of the third clamping groove 112, and the second blocking surface 1112 is used to prevent the fourth flange 221 from escaping from the third clamping groove 112, thereby improving the reliability of the clamping connection between the inner cover 22 of the clamping cover and the bottle mouth 11, thereby preventing the airtightness of the cosmetic bottle from being damaged, resulting in failure of the vacuum pump body 21 and oxidation of the cosmetics.

[0031] In this embodiment, the bottle mouth 11 is provided with a first stop portion 113, the inner wall and outer periphery of the card cover inner cover 22 are respectively provided with a second stop portion 223 and a third stop portion 224, and the inner wall of the card cover outer cover 23 is provided with a fourth stop portion 232; when the card cover inner cover 22 is engaged with the bottle mouth 11, the first stop portion 113 is plugged into the second stop portion 223, and when the card cover outer cover 23 is engaged with the card cover inner cover 22, the third stop portion 224 is plugged into the fourth stop portion 232. The first stop portion 113 and the second stop portion 223 are used to prevent the card cover inner cover 22 from rotating relative to the bottle mouth 11, thereby preventing the card connection between the two from being worn due to rotation, thereby destroying the airtightness of the cosmetic bottle; similarly, the third stop portion 224 and the fourth stop portion 232 are used to prevent the card cover inner cover 22 and the card cover outer cover 23 from rotating, further preventing the airtightness of the cosmetic bottle from being destroyed.
