Description

Technical Field

[0001] The utility model relates to an integrated PET roll-on bottle, belonging to the technical field of daily necessities. Background Art

[0002] A roll-on bottle is a common packaging bottle and is widely used in the cosmetics field. The existing roll-on bottle includes a bottle body, a bottle cap, a ball holder and a roll-on ball. The bottle body and the ball holder are two independently formed parts. When in use, the ball holder needs to be installed at the opening at the upper end of the bottle body, and then the roll-on ball is assembled into the ball holder. The liquid in the bottle body is brought out by the rolling of the ball. In addition, the bottle body, bottle cap, ball holder and roll-on ball are usually made of different materials. For example, because it is necessary to observe the condition of the liquid in the bottle body, the bottle body is made of glass material, and the bottle cap, ball holder and roll-on ball are made of different plastic materials. This requires the components to be disassembled for recycling, which is very inconvenient and not in line with the concept of environmental protection. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an integrated PET roll-on bottle, which is easy to assemble and recycle, and can solve the shortcomings of the prior art.

[0004] The technical solution of the utility model is: an integrated PET roller ball bottle, comprising a bottle body, a bottle cap, and a roller ball, the bottle cap can be covered on the bottle body, the bottle body is a transparent bottle body, the bottle body, the bottle cap, and the roller ball are all made of PET material, the neck of the bottle body has an arc-shaped supporting portion extending inwardly and integrally formed therewith, a cavity is formed between the arc-shaped supporting portion and the opening at the top of the bottle body for placing and rolling the roller ball, and a liquid outlet is provided at the center of the arc-shaped supporting portion.

[0005] Furthermore, the ball is a hollow ball.

[0006] Furthermore, the ball bearing is composed of two hollow hemispheres welded together.

[0007] Furthermore, the outer surface of the ball bearing is a frosted surface.

[0008] Furthermore, the bottle cap has a resisting portion cooperating with the ball. When the bottle cap is closed on the bottle body, the resisting portion presses the ball tightly so that the ball blocks the liquid outlet.

[0009] Furthermore, the outer wall of the bottle cap has an anti-slip concave-convex structure.

[0010] By implementing the utility model, all parts of the roller ball bottle (bottle body, bottle cap, roller ball) are made of PET material, and do not need to be disassembled during recycling, which is convenient and environmentally friendly. The bottle body has good light transmittance, which can facilitate observation of the use of the liquid in the bottle body; the bottle body has a cavity for placing and rolling the roller ball, which reduces the parts of the ball holder, reduces the mold cost and assembly steps, and can save costs and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 This is a schematic diagram of the bottle cap of the utility model in an open state.

[0013] As shown in the figure: bottle body 1; bottle cap 2; ball bearing 3; arc-shaped supporting part 4; liquid outlet 5; concave-convex pattern 6; and resisting part 7. DETAILED DESCRIPTION

[0014] Embodiments of the present utility model: Figure 1 to Figure 2 As shown, an integrated PET roller ball bottle comprises a bottle body 1, a bottle cap 2, and a roller ball 3. The bottle cap 2 can be covered on the bottle body 1. The bottle body 1 of the present application is a transparent bottle body. The bottle body 1, the bottle cap 2, and the roller ball 3 are all made of PET materials. They do not need to be disassembled during recycling, which is convenient and environmentally friendly. The bottle body 1 is made by injection blowing technology. The neck of the bottle body 1 has an arc-shaped supporting portion 4 extending inwardly and integrally formed with it. A cavity for placing and rolling the roller ball 3 is formed between the arc-shaped supporting portion 4 and the opening at the top of the bottle body. A liquid outlet hole 5 is provided at the center of the arc-shaped supporting portion. The roller ball 3 is directly installed in the cavity of the bottle body 1. The liquid in the bottle body 1 enters the cavity through the liquid outlet hole 5 and is rolled on the skin by the roller ball 3, thereby reducing the parts of the traditional ball holder, reducing the mold cost and assembly steps, and saving costs and improving production efficiency.

[0015] As a preferred embodiment, the ball 3 is a hollow ball, which is composed of two hollow hemispheres welded together to reduce the amount of material used. After the two hollow hemispheres are welded together, the weld line is removed by grinding and the outer surface of the ball is made frosted, which increases the surface friction of the ball 3 and makes the outer surface have good flatness.

[0016] As a preferred embodiment, the bottle cap 2 has a resisting portion 7 that cooperates with the ball 3. When the bottle cap 2 is closed on the bottle body 1 by snapping or threading, the resisting portion 7 presses the ball 3 so that the ball 3 blocks the liquid outlet 5, so that when the bottle cap 2 is closed on the bottle body 1, the liquid in the bottle body 1 is prevented from flowing into the cavity, and the bottle cap 2 has good sealing performance.

[0017] As a preferred embodiment, the outer wall of the bottle cap 2 has anti-slip concave-convex patterns 6, which are the concave-convex structures mentioned above, which increase the friction of the outer wall of the bottle cap 2 and facilitate the opening and closing operation.
