[0003] For existing cosmetic lotion bottles, generally, people need to turn the bottle body over to pour out the cosmetics. When in use, when it is almost used up, a large amount of lotion often adheres to the inner wall and bottom, and it cannot be poured out, resulting in great waste. And the single glass material will collide with the ground or other hard objects during use, and it is easy to cause the glass bottle to break or leak. Summary of the Invention

[0004] The purpose of the present invention is to provide a glass bottle and its spraying process to solve the above-mentioned defects in the prior art.

[0005] A glass bottle includes a bottle body, an outer cover body and an inner cover body. A gasket is attached to the bottom end of the bottle body. A closing mechanism is arranged directly above the bottle body. The closing mechanism seals and protects the top end of the bottle body, and at the same time flexibly wraps a part of the bottle body to reduce the impact force generated by the collision of the bottle body with hard objects. A scraping mechanism is arranged inside the bottle body. The scraping mechanism scrapes the remaining cosmetics inside the bottle body, and at the same time facilitates the secondary filling of bagged cosmetics into the bottle body. An inner cover body is arranged directly above the bottle body, and a discharge through hole is penetrated and opened at the top end of the inner cover body.

[0006] Preferably, the closing mechanism includes an outer cover body, a corrugated rubber sleeve, an inner tooth disc body, an annular rubber ring and an outer tooth sleeve body. A corrugated rubber sleeve is attached to the outside of the outer cover body. An outer tooth sleeve body is arranged inside the outer cover body. An annular rubber ring is attached to the inner end of the outer cover body. The outer tooth sleeve body is arranged directly above the bottle body. The inner end of the corrugated rubber sleeve is attached to the bottle body. The inner tooth disc body is arranged inside the outer cover body, and the outer cover body is arranged directly above the bottle body.

[0007] Preferably, the outer cover body is attached to the top end of the discharge through hole through the annular rubber ring arranged inside.

[0008] Preferably, the outer cover body is connected to the outside of the inner tooth disc body through the outer tooth sleeve body arranged inside.

[0009] Preferably, the scraping mechanism includes a mixing shaft, an inner cover body, a positioning disc body, a ratchet wheel, an externally meshing disc and a scraping blade. The top end of the mixing shaft is provided at the bottom end of an internal tooth disc body. The bottom end of the mixing shaft is connected with a scraping blade, and the scraping blade is arranged inside the bottle body. The positioning disc body is arranged inside the inner cover body, an externally meshing disc is arranged inside the positioning disc body, and the outer end of the mixing shaft is connected through a ratchet wheel.

[0010] Preferably, the mixing shaft is connected to the outside of the externally meshing disc through a ratchet wheel connected by an outer key.

[0011] Preferably, the width of the externally meshing disc is half of the width of the positioning disc body.

[0012] Preferably, for the spraying process of the glass bottle described above, the steps are as follows: Pretreatment of the glass bottle: Place the glass bottle to be sprayed in an ultrasonic cleaning device, add a cleaning agent containing a surfactant, clean at a temperature of 40 - 60 °C for 10 - 15 minutes to remove oil stains and impurities on the bottle body surface; after cleaning, conduct high-pressure flushing with deionized water, and then place it in a drying oven at 80 - 100 °C for drying for 20 - 30 minutes to make the glass bottle surface clean and dry;

[0013] Surface activation treatment: Put the dried glass bottle into a plasma treatment device, under the condition of a vacuum degree of 10 - 50 Pa, introduce argon gas, and treat it at a power of 100 - 200 W for 3 - 5 minutes to improve the surface activity of the glass bottle and enhance the coating adhesion;

[0014] Spraying primer: Pour the prepared primer into the storage tank of an automatic spraying device, adjust the spray gun pressure to 0.3 - 0.5 MPa, keep the spraying distance at 15 - 25 cm, and spray the primer on the glass bottle at a uniform speed, with the coating thickness controlled within 10 - 15 μm; after spraying, send the glass bottle into a curing furnace and cure it at a temperature of 120 - 150 °C for 15 - 20 minutes;

Qualified products are packaged, and unqualified products are reworked or scrapped.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The design of this mechanism adopts the intermittent motion principle of the ratchet mechanism to realize the switching between the positioning and scraping functions. In the positioning stage, the downward pressing operation makes the ratchet pawl of the ratchet wheel embed into the ratchet teeth of the outer meshing wheel disc, and the axial fixed stop pawl cooperates through the tooth surface engagement to prevent reverse displacement and ensure positioning stability; in the scraping stage, the pawl-ratchet engagement is released by the upward action, releasing the axial degree of freedom, and the shaft can drive the scraper to realize a 360° rotation scraping operation. This structure is particularly suitable for the scraping process of cosmetic bottles, and the risk of electrical component contamination can be avoided through mechanical positioning.

[0019] 2. Add a design of a sealing cover on the top of the cosmetic glass bottle. The specific advantages are as follows: the use of a double-layer cover structure such as an inner cover + an outer cover can reduce air infiltration. The outer cover blocks the discharge hole through the annular rubber ring set inside, thereby reducing the oxidation rate of the active ingredients in the cosmetics. The polypropylene bottle cap is designed with a corrugated rubber sleeve to protect part of the glass bottle, reduce the impact of hard objects on it, and effectively block the volatilization of moisture.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 5As shown in the figure, a glass bottle includes a bottle body 1, an outer cover body 3 and an inner cover body 8. A gasket 2 is attached to the bottom end of the bottle body 1. A sealing mechanism 4 is provided directly above the bottle body 1. The sealing mechanism 4 seals and protects the top end of the bottle body 1, and at the same time flexibly wraps a part of the bottle body 1 to reduce the impact force generated by the collision between the bottle body 1 and hard objects. A scraping mechanism 13 is provided inside the bottle body 1. The scraping mechanism 13 scrapes the remaining cosmetics inside the bottle body 1, and at the same time facilitates the secondary filling of bagged cosmetics into the bottle body 1. An inner cover body 8 is provided directly above the bottle body 1, and a discharge through hole 12 is formed through the top end of the inner cover body 8.

[0029] In this embodiment, the sealing mechanism 4 includes an outer cover body 3, a corrugated rubber sleeve 5, an internal gear disk body 7, an annular rubber ring 14 and an outer tooth sleeve body 15. A corrugated rubber sleeve 5 is attached to the outside of the outer cover body 3. An outer tooth sleeve body 15 is provided inside the outer cover body 3. An annular rubber ring 14 is attached to the inner end of the outer cover body 3. The outer tooth sleeve body 15 is provided directly above the bottle body 1. The inner end of the corrugated rubber sleeve 5 is attached to the bottle body 1. The internal gear disk body 7 is provided inside the outer cover body 3. The outer cover body 3 is provided directly above the bottle body 1.

[0030] In this embodiment, the outer cover body 3 is attached to the top end of the discharge through hole 12 through the annular rubber ring 14 provided inside, and the discharge through hole 12 is blocked by the annular rubber ring 14 to prevent external air from oxidizing the internal cosmetics.

[0031] In this embodiment, the outer cover body 3 is connected to the outside of the internal gear disk body 7 through the outer tooth sleeve body 15 provided inside. The outer cover body 3 is connected to the internal gear disk body 7 through the outer tooth sleeve body 15 provided inside the outer cover body 3, improving the connection stability of the outer cover body 3.

[0032] The scraping mechanism 13 includes a mixing shaft 6, an inner cover body 8, a positioning disk body 9, a ratchet wheel 10, an external meshing gear disk 11 and a scraping blade 16. The top end of the mixing shaft 6 is provided with the bottom end of the internal gear disk body 7. The bottom end of the mixing shaft 6 is connected to a scraping blade 16. The scraping blade 16 is provided inside the bottle body 1. The positioning disk body 9 is provided inside the inner cover body 8. An external meshing gear disk 11 is provided inside the positioning disk body 9. The outer end of the mixing shaft 6 is connected through a ratchet wheel 10.

[0033] In this embodiment, the mixing shaft 6 is connected to the outside of the external meshing gear disk 11 through the ratchet wheel 10 connected by a key on the outside. The external meshing gear disk 11 engages with the ratchet wheel 10 to prevent the internal gear disk body 7 provided at the top end of the mixing shaft 6 from rotating and affecting the connection between the internal gear disk body 7 and the outer tooth sleeve body 15.

[0034] In this embodiment, the width of the external engagement disk 11 is half of the width of the positioning disk body 9, facilitating the displacement separation between the external engagement disk 11 and the interior of the positioning disk body 9, and facilitating the rotation of the scraping blade 16 driven by the mixing shaft 6.

[0035] When this glass bottle is actually applied, it includes the following working contents:

[0036] Step 1: During use, the top end of the bottle body 1 is sealed by the inner cover body 8. Subsequently, by pressing down the internal gear disk body 7, the internal gear disk body 7 drives the mixing shaft 6 and the ratchet 10 connected to the outside to move downward, so that the ratchet 10 is engaged with the outside of the external engagement disk 11. Furthermore, the mixing shaft 6 is positioned by using the ratchet 10 and the external engagement disk 11. At the same time, the rotation of the internal gear disk body 7 provided at the top end of the mixing shaft 6 is avoided, so that the internal gear disk body 7 is aligned with the internal external tooth sleeve body 15 of the outer cover body 3, and the external tooth sleeve body 15 is connected to the internal gear disk body 7, so that the outer cover body 3 seals the top end of the bottle body 1;

[0037] Step 2: At the same time, the outer cover body 3 moves vertically down to the bottle body 1, so that the annular rubber ring 14 provided on the outside of the outer cover body 3 presses down on the surface of the inner cover body 8, so that the discharge through hole 12 opened at the top end of the inner cover body 8 is attached to the annular rubber ring 14 to block and seal the discharge through hole 12. At the same time, a part of the corrugated rubber sleeve 5 provided on the outside of the outer cover body 3 is displaced to cover a part of the outside of the bottle body 1, increasing the friction of the outer cover body 3, and also facilitating the holding of the annular rubber ring 14 when the hand is wet, and driving the inner cover body 8 and the external tooth sleeve body 15 to rotate by using the annular rubber ring 14;

[0038] Step 3: During normal use, the operator rotates the outer cover body 3 in the reverse direction, so that the external tooth sleeve body 15 provided inside the outer cover body 3 is separated from the internal gear disk body 7. By tilting the bottle body 1, the cosmetics inside the outer cover body 3 are poured out through the opened discharge through hole 12. The gasket 2 provided at the bottom end of the bottle body 1 contacts the tabletop to increase the friction of the bottle body 1 and prevent the glass bottle from slipping due to being too smooth;

[0039] Step 4: When it is necessary to scrape the residual cosmetics inside the bottle body 1, the operator lifts the internal gear disk body 7, so that the mixing shaft 6 and the ratchet 10 provided at the bottom end of the internal gear disk body 7 are lifted. By the lifting action, the pawl outside the ratchet 10 is disengaged from the external engagement disk 11, releasing the axial degree of freedom. The mixing shaft 6 can drive the scraping blade 16 to achieve 360°, so that the scraping blade 16 scrapes and cleans the residual cosmetics inside the bottle body 1, and the residual cosmetics are discharged through the discharge through hole 12.

[0040] Spraying process for glass bottles, the steps are as follows: Pretreatment of glass bottles: Place the glass bottles to be sprayed in an ultrasonic cleaning device, add a cleaning agent containing a surfactant, clean at a temperature of 40 - 60 °C for 10 - 15 minutes to remove oil stains and impurities on the bottle surface; after cleaning, conduct high-pressure flushing with deionized water, and then place it in a drying oven at 80 - 100 °C for drying for 20 - 30 minutes to make the glass bottle surface clean and dry;

[0041] Surface activation treatment: Put the dried glass bottles into a plasma treatment device, under the condition of a vacuum degree of 10 - 50 Pa, introduce argon gas, and treat at a power of 100 - 200 W for 3 - 5 minutes to improve the surface activity of the glass bottles and enhance the coating adhesion;

[0042] Spraying primer: Pour the prepared primer into the storage tank of the automatic spraying device, adjust the spray gun pressure to 0.3 - 0.5 MPa, keep the spraying distance at 15 - 25 cm, and spray the primer on the glass bottles at a uniform speed, with the coating thickness controlled at 10 - 15 μm; after spraying, send the glass bottles into a curing furnace and cure at a temperature of 120 - 150 °C for 15 - 20 minutes;

[0043] Spraying topcoat: Replace the topcoat paint to the spraying device, adjust the spray gun parameters, keep the pressure at 0.3 - 0.5 MPa, and the spraying distance at 20 - 30 cm, and spray the topcoat evenly on the glass bottles, with the coating thickness controlled at 15 - 20 μm; after spraying, send the glass bottles into the curing furnace again and cure at a temperature of 150 - 180 °C for 20 - 30 minutes to form a wear-resistant and scratch-resistant protective layer;

[0044] Cooling and quality inspection: Naturally cool the cured glass bottles to room temperature, and use methods such as visual inspection, film thickness measurement, and adhesion test to inspect the appearance, thickness, adhesion and other indicators of the glass bottle coating. Qualified products are packaged, and unqualified products are reworked or scrapped.

[0045] Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
