Description

Bottle blank with leakage-proof structure on bottle mouth

Technical Field

The utility model relates to a bottle base technical field specifically is a bottle base that bottleneck has antiseep structure.

Background

The PET plastic has the characteristics of light weight, high transparency, impact resistance, difficult fragmentation and the like, is widely applied to the fields of articles for daily use, daily chemical packaging and the like, and is particularly applied to the aspect of bottled mineral water packaging. The structure of bottle base plays important influence to the shaping quality of bottle, and current bottleneck outer wall is straight column, has certain lack in the aspect of the leakproofness, is changing bottleneck outer wall into the bottleneck outer wall of slope alpha angle (as shown in figure 1), but because the shrink degree of bottleneck outer wall is different and forms certain sunken, this for a moment makes between bottleneck outer wall and the bottle lid because of the thickness inconsistent and make the seepage problem between the two.

Therefore, it is desirable to develop a leak-proof bottle neck structure to solve this problem.

Disclosure of Invention

An object of the utility model is to provide a bottleneck has bottle base of prevention of seepage leak structure adds certain arc structure at the bottleneck outer wall and is used for compensating shrink, reduces the bottleneck wall thickness simultaneously, guarantees the structural performance of bottleneck through increasing the strengthening rib in bottleneck department to solve the problem that proposes in the above-mentioned background art.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

the bottle blank with the bottle opening provided with the anti-leakage structure comprises a blank opening, a blank neck, a blank body and a blank bottom, wherein the outer wall of the blank opening and the central axis of the bottle blank form an alpha included angle, the outer wall of the blank opening is in the shape of a micro arc, the wall thickness of the blank neck is smaller than that of the outer end face of the blank opening, and a plurality of reinforcing ribs parallel to the central axis of the bottle blank are arranged on the outer wall of the blank neck.

Furthermore, the included angle alpha between the outer wall of the blank opening and the central axis of the bottle blank is 8-15 degrees.

Furthermore, the radius R of the slight arc shape of the blank mouth outer wall is 55mm-60 mm.

Furthermore, a plurality of reinforcing ribs arranged on the outer wall of the billet neck are symmetrically arranged, and the number of the reinforcing ribs is 4-8.

The utility model has the advantages that:

the utility model discloses an add certain little convex structure at the bottleneck outer wall and be used for compensating the shrink, can reduce the seepage problem that the combination is not tight and leads to between bottle lid and the bottleneck outer wall by a wide margin, increased the closure, simultaneously, the weight of bottle base does not increase because of the slope design of bottleneck outer wall for guaranteeing, has consequently reduced the bottleneck wall thickness to guarantee the structural performance of bottleneck through increasing the strengthening rib in bottleneck department.
