The present invention relates to bottles, and more particularly to a bottle with a reinforcing structure for the sidewall around its bottle lip.
In use, many of the aforementioned bottles may be stacked vertically with contents contained in the bottle bodies 91 thereof. However, it is found in practice that such a conventional bottle is somehow disadvantageous because its bottle body 91 is structurally weak at the shoulder 92. Particularly, the rounded connecting parts 95 can sink when the bottle receives heavy downward load at its top, leading to deformation at the shoulder 92. Hence, there is a need for improvement in the prior art.
The primary objective of the present invention is to address the foregoing problem by providing a reinforcing structure for a sidewall around a bottle lip. The bottle has its bottle body atop provided with a plurality of lateral faces and slopes that form a sidewall with better structural strength, so as to prevent the bottle from sinking and deformation when it receives a heavy downward load.
For achieving the foregoing objective, the present invention provides a reinforcing structure for a sidewall around a bottle lip. The sidewall is a shoulder in an upper part of a bottle body that has the bottle lip atop the shoulder. The reinforcing structure is such formed that the shoulder is a chamfered rectangular structure in a direction parallel to a width of the bottle body, and four vertical lateral faces support the bottle lip from below. A slope is formed at a corner between any two adjacent lateral faces and has a downward-narrowed facade. All of the lateral faces and the slopes are plane and flat in geometry. Each of the lateral faces has a downward-widened facade defined by the slopes flanking it from two sides, while each of the lateral faces has an upper edge thereof locationally close to the base of the bottle lip.
Therein, each said lateral face is angularly jointed to the slopes at the two sides thereof by round corners.
Therein, the bottle body has a part below the shoulder formed as a chamfered rectangular structure conforming to the shoulder.
Referring to
In the present invention, a reinforcing structure for a sidewall around a bottle lip, as in one preferred embodiment shown in
As shown in
With the disclosed reinforcing structure, the bottle body 1 has the shoulder 2 is roughly a chamfered rectangular structure in the direction parallel to the width of the bottle, and there are four vertical lateral faces 21 supporting the bottle lip 3 from below, with the slope 22 formed at the corner between any two adjacent lateral faces 21. Since the lateral faces 21 and the slopes 22 are plane and flat in geometry while each said slope 22 has a downward-narrowed facade so that each said lateral face 21 has a downward-widened facade defined by the slopes 22 flanking it from two sides, and each of the lateral faces 21 has its upper edge 211 locationally close to the base 31 of the bottle lip 3, the disclosed structure effectively reinforces the shoulder 2. As compared to the conventional bottle, when the same load in applied downward at the bottle lip 3, the sidewall of the bottle lip of the present invention is much stronger and much less likely to sink thanks to the reinforcing structure, thereby protecting the vertically stacked bottle bodies from deformation.
