Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the embodiment of the present utility model provides a bottle neck structure for facilitating opening, comprising an end cap 1 and a screw neck 2 screw-coupled to the end cap 1, wherein the end cap 1 is divided into an inner end surface and an outer end surface, the end cap 1 is provided with an internal screw thread, and the end cap 1 is screw-coupled to the screw neck 2 through the internal screw thread. The outer end face is provided with a caliper structure 12. The screw neck 2 is provided with sealing plate 21 in the upper end, and sealing plate 21 is used for sealing screw neck 2, is provided with protruding structure 22 on the sealing plate 21, and protruding structure 22 is located sealing plate 21 towards the one side of end cover 1, and calliper structure 12 is used for the joint on protruding structure 22.

In this embodiment, the caliper structure 12 is snapped onto the boss structure 22 for opening purposes by pulling upward to tear the closure flap 21. The sealing piece 21 can avoid the influence of hot pressing fastness on the sealing degree, so that the sealing property is ensured, and the requirement of a processing technology is reduced.

The boss structure 22 is provided at the center of the sealing plate 21, and the caliper structure 12 is provided at the center of the end cap 1.

In some embodiments of the utility model, the flap 21 is arcuate, the flap 21 is recessed toward the end remote from the end cap 1, and the edge of the flap 21 is lower than the upper end of the threaded neck 2. In this embodiment, the sealing plate 21 is arc-shaped, and the sealing plate 21 has a certain height difference from the upper end of the threaded neck 2, so that the caliper structure 12 uses the lever principle to pry the protruding structure 22 with the side wall of the threaded neck 2 as a fulcrum, and thus the sealing plate 21 is torn from one end with a small force. The lower end closure 21 than the thread neck 2 also ensures the integrity of the top end of the thread neck 2 during tearing.

Preferably, the thickness of the sealing sheet 21 is gradually reduced from the center to the edge so as to weaken the connection strength of the sealing sheet and the threaded neck 2 at the connection position, and avoid that the connection strength of the sealing sheet and the threaded neck is too high to tear the sealing sheet 21.

In some embodiments of the utility model, the connection between the sealing piece 21 and the threaded neck 2 is preset with a score line, when the sealing piece 21 is stressed, the sealing piece 21 is opened along the preset score line, so that the sealing piece 21 is prevented from being broken in the opening process, and the sealing piece 21 cannot be completely torn off.

In some embodiments of the utility model, the protruding structure 22 is integrally in a T-shaped rotation shape, and the protruding structure 22 includes a connection portion and a clamping portion, the connection portion is disposed at the center of the sealing sheet 21, and the clamping portion is disposed on the connection portion. The caliper structure 12 is provided with a receiving groove 121 and a passage communicating with the receiving groove 121, and the receiving groove 121 is the same shape as the protrusion structure 22. The protruding structure 22 slides into the accommodating groove 121 from the side surface of the caliper structure 12, so that the protruding structure 22 is clamped with the caliper structure 12.

In some embodiments of the utility model, the junction of the engagement portion and the connection portion is chamfered. The outer surface of the caliper structure 12 is rounded to form an outer contour with the same curvature as the arc-shaped sealing plate 21, so that the caliper structure 12 is prevented from piercing the sealing plate 21 in the lever motion process.

In some embodiments of the utility model, the lateral outer edges of the end cap 1 are provided with anti-skid patterns 13.

In some embodiments of the present utility model, the sealing plate 21 and the threaded neck 2 are integrally formed, and both the sealing plate 21 and the threaded neck 2 are made of PP material. The PP material has certain hardness and strength, avoids the fracture of the sealing plate 21 in the stress process, has good compatibility with the material body, and avoids polluting the dye body.

As shown in fig. 4, the present application further provides a container, which further includes a bottle body 3 outside the bottle neck structure, wherein the threaded neck 2 is mounted on the bottle body 3, and the material in the bottle body 3 flows out through the threaded neck 2.

In some embodiments of the utility model, the body 3 may be made of a flexible material, such as a hose; but also hard materials such as hard plastics.

While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
