Fig. 6 shows a specific structure of a cross-sectional view of a connection between the receiving portion 10 and the lid 20.

Hereinafter, the thin wall portion 113 will be described by taking an example in which the plastic container 1 is formed by integral molding.

As shown in fig. 5 and 6, in some examples, the plastic container 1 may have a thin-walled region 113. The cap 20 and the opening 111 of the neck 11 may be connected to each other by a thin-walled region 113. In other words, the thin-walled region 113 defines the bottom edge 20b of the cap body 20 and the top edge 11b of the neck 11.

In some examples, the thin-walled region 113 may be a region of lesser wall thickness on the plastic container 1. In other words, the wall thickness of the thin-walled region 113 may be thinner than the wall thickness of the cap body 20 and the neck portion 11. In this case, the thin-walled region 113 is a weak region on the plastic container 1, whereby the plastic container 1 is easily broken at the thin-walled region 113. In other examples, the thin-walled area 113 may also be a perforation or score line formed on the plastic container 1. In other examples, the thin-walled area 113 may also be a crease formed by pre-folding the plastic container 1 at a desired location. In other examples, the thin-walled region 113 may also be another method of damaging the integrity of the plastic container 1 at the location of the thin-walled region 113 by at least one of chemical, thermal, or mechanical energy. It should be noted that the method of obtaining the thin-walled region 113 described above does not produce openings in the plastic container 1 that could allow the fluid product contained in the containment space 13 to leak out.

In some examples, the wall thickness of the thin-walled region 113 may be no greater than 0.3 mm. For example, the wall thickness of the thin-walled region 113 may be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, or 0.3 mm. In some examples, the cross-sectional area of thin-walled region 113 may be no greater than 5mm ² For example, the cross-sectional area of the thin-walled region 113 may be 1mm ² 、1.5mm ² 、2mm ² 、2.5mm ² 、3mm ² 、3.5mm ² 、4mm ² 、4.5mm ² Or 5mm ² 。

In the present embodiment, the operating portion 22 of the lid body 20 is biased so that the operating portion 22 swings relative to the plastic container 1 in a space defined by an angle β between the wall surface 20a of the lid body 20 and the wall surface 11a of the neck portion 11. In other words, the cap 20 swings with respect to the neck 11. In addition, the cap 20 may be rotated with respect to the neck 11. In other words, the cap body 20 is screwed. In this case, the plastic container 1 can be broken at the weakened, thin-walled region 113, and the cap body 20 is disconnected from the neck portion 11. In other words, the cover 20 can be disconnected from the container 10. Since the cap 20 does not need to be screwed excessively, the opened bottle mouth (i.e., the opening 111) can be kept relatively regular, so that the plastic container 1 can form a thin cylindrical flow column after being pressed.

According to the utility model discloses, can provide one kind and easily open and the bottleneck can keep regular plastic container 1 relatively after opening.

While the present invention has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the invention in any way. The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
