Description

Technical Field

[0001] This utility model relates to the field of machinery, specifically to a novel capping device. Background Technology

[0002] How the cap works:

[0003] Threaded seal: The bottle cap and bottle mouth usually have matching threads. When the bottle cap is tightened, the threads interlock tightly, causing the bottle mouth to gradually penetrate into the bottle cap, generating contact pressure, thereby ensuring that the bottle mouth and the sealing gasket fit tightly, preventing leakage of the contents of the bottle and the entry of outside air and bacteria.

[0004] Rotation opening: By applying external force, the bottle cap rotates in the opposite direction to the bottle opening, overcoming the friction between the threads, thereby causing the bottle cap to come off the bottle opening. The process of unscrewing the bottle cap can be seen as an application of the wheel and axle principle. Think of the bottle cap as the wheel and the bottle body as the axle. Turn your hands in opposite directions and the bottle cap will be unscrewed.

[0005] Anti-theft design: The bottle cap and the anti-theft ring are connected by a connecting bridge. When the bottle cap is opened, the connecting bridge will break, thus determining whether the bottle has been opened. This also increases the steps and difficulty of opening the bottle to some extent.

[0006] Currently, most blow-molded bottles on the market use screw caps, which need to be opened by rotating. The traditional opening method has the following problems: 1. It is difficult to open by hand, especially for children or people with weak hand strength; 2. The outer wall of the oil bottle cap is mostly angular, and it is not friendly to the hands to twist the cap repeatedly. Summary of the Invention

[0007] In order to solve the technical problems of existing screw caps being difficult to open and bad for the hands, this application proposes a new type of capping device that solves the above-mentioned technical problems.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] This utility model provides a novel capping device, including an assisting ring sleeve that can be fitted onto the outer ring of a bottle cap. The assisting ring sleeve includes two openable and closeable assisting semi-rings. One end of each assisting semi-ring is a hinged end, and the other end is a movable end. The hinged ends of the two assisting semi-rings are rotatably connected. The inner wall surface of each assisting semi-ring has an anti-slip pattern that matches the outer ring of the bottle cap, and the outer wall surface of each assisting semi-ring has multiple arc-shaped protrusions for increasing friction.

[0010] Furthermore, it also includes an assist arm connected to the assist semi-ring.

[0011] Furthermore, a circumferential groove is provided on the ring body of the assisting half ring, and one end of the assisting arm is rotatably connected to the circumferential groove so that the assisting arm can be rotated and retracted into the circumferential groove.

[0012] Furthermore, the connection point between the assist arm and the assist half-ring is located near the hinge point of the two assist half-rings.

[0013] Furthermore, a round pin is fixed inside the container groove, and correspondingly, a pin hole that mates with the round pin is opened at one end of the assist arm.

[0014] Furthermore, a pivot is provided on the hinge end of one of the assisting half-rings, and a cylindrical protrusion is formed on the hinge end of the other assisting half-ring, wherein an insertion hole is provided on the cylindrical protrusion to cooperate with the pivot.

[0015] Furthermore, an arc-shaped block for assisting rotation is formed on the hinge end of the assisting half-ring with the rotating shaft, and the rotating shaft and the arc-shaped block are arranged concentrically.

[0016] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0017] This novel capping device assists in opening bottle caps by first opening two assisting semi-rings and placing them on the outer ring of the cap. Then, the two semi-rings are closed, ensuring a perfect fit. The anti-slip pattern on the inner wall of the semi-rings engages with the sharp triangular anti-slip pattern on the outer ring of the cap. A rotational force is then applied to the multiple arc-shaped protrusions on the outer wall of the semi-rings to increase friction. Because the diameter of the assisting ring is larger than the diameter of the cap, the torque is increased, allowing the cap to be opened with less effort. Furthermore, the arc-shaped protrusions on the outer wall of the semi-rings are much smoother than the sharp triangular anti-slip pattern on the cap, making them more hand-friendly.

[0018] The novel capping device of this utility model is also equipped with an assist arm to further increase the torque, making the capping process more labor-saving.

[0019] The novel capping device of this utility model has an assisting arm that can be stored and folded into the corresponding container slot. After folding, the device is more compact and convenient to carry. Attached Figure Description
