Description

Technical Field

[0001] The utility model relates to the technical field of bottle mouths of liquid containers, in particular to a large-diameter bottle mouth. Background Art

[0002] Plastic liquid containers (such as drinking water bottles and barrels) are generally made by injection molding and blow molding. However, the existing drinking water bottles have a small mouth, which leads to a lot of material accumulation in the neck when blowing the bottle, resulting in a too thick neck, resulting in a waste of raw materials and an increase in the weight of the bottle.

[0006] The outer diameter of the bottle mouth body is greater than 59 mm.

[0007] Furthermore, the connecting component includes a clamping platform coaxially arranged outside the bottle mouth body, and the bottle cap is clamped and fixed to the clamping platform.

[0008] Furthermore, the clamping platform includes an arc-shaped guiding portion and a flat clamping portion.

[0009] Furthermore, the top of the inner wall of the bottle mouth body is an S-shaped structure.

[0010] Furthermore, the top of the outer wall of the bottle mouth body is convex.

[0011] Furthermore, the connecting member includes an external thread arranged outside the bottle mouth body.

[0012] Furthermore, a safety platform is provided between the external thread and the support platform, and the outer diameter of the safety platform is larger than the outer diameter of the external thread.

[0013] Furthermore, the cross section of the support platform is trapezoidal.

[0014] The beneficial effects of the utility model are:

[0015] The bottle mouth of the utility model has a large diameter. When the bottle mouth and the bottle body are integrally formed, the material used for the bottle mouth is increased, thereby reducing the accumulation of raw materials at the bottleneck. The bottle mouth has good extensibility and can be better blown. At the same time, the bottle mouth wall thickness is thinned, and the bottle cap and the bottle mouth are snap-fitted to achieve a light and thin bottle mouth. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] Embodiment 1:

[0025] like Figure 1-3 As shown, a large-diameter bottle mouth comprises a bottle mouth body 1, wherein the bottle mouth body 1 is provided with a connecting member and a supporting platform 2 in sequence from top to bottom, wherein the connecting member is used to fix the bottle cap, and an installation groove 3 for installing an anti-theft ring is formed between the connecting member and the supporting platform 2;

[0026] The outer diameter of the bottle mouth body 1 is 60 mm±0.15 mm.

[0027] The wall thickness of the bottle mouth body 1 is 2 mm, which is thinner than the conventional bottle mouth with a wall thickness of 3 mm.

[0028] The connecting member comprises a clamping platform 4 coaxially arranged outside the bottle mouth body 1 , and the bottle cap is clamped and fixed to the clamping platform 4 .

[0029] The clamping platform 4 includes an arc-shaped guide portion and a flat clamping portion. The guide portion is used to guide the bottle cap downward when the bottle cap is buckled, so as to facilitate the cooperation between the buckling portion inside the bottle cap and the clamping portion. The bottle cap and the bottle mouth are designed to be buckled, and only the material of the clamping platform 4 needs to be considered during molding, which reduces the material of multiple turns of thread.

[0030] The top of the inner wall of the bottle mouth body 1 is an S-shaped structure. The top of the inner wall of the bottle mouth body 1 is arranged in this way to facilitate the inner seal of the bottle cap to enter the bottle mouth and form a seal with the bottle mouth when the bottle cap is assembled; at the same time, the arrangement of this structure can form at least two layers of seal between the inner wall of the bottle mouth and the top of the bottle mouth, thereby improving the sealing effect at the bottle mouth.

[0031] like Figure 3 As shown, the top of the outer wall of the bottle mouth body 1 is convex. The purpose of such a setting is to adapt (follow the shape) the S-shaped structure of the top of the inner wall of the bottle mouth body 1 so that the bottle mouth maintains a uniform wall thickness.

[0032] The bottle mouth of the utility model has a large diameter. When the bottle mouth and the bottle body are integrally formed, the material used for the bottle mouth is increased, thereby reducing the accumulation of raw materials at the bottleneck. The bottle mouth has good extensibility and can be better blown. At the same time, the bottle mouth wall thickness is thinned, and the bottle cap and the bottle mouth are snap-fitted to achieve a light and thin bottle mouth.

[0033] Embodiment 2:

[0034] like Figure 4 and Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the connecting member includes an external thread 5 arranged outside the bottle mouth body 1.

[0035] A safety platform 6 is provided between the external thread 5 and the support platform 2 , and the outer diameter of the safety platform 6 is greater than the outer diameter of the external thread 5 .

[0036] The cross section of the support platform 2 is trapezoidal.

[0037] In this embodiment, the bottle cap is threadedly matched with the bottle mouth.

[0038] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
