Problems solved by technology

Therefore, there is a problem that the container tends to drop from the neck clamp inserted between the flange portion 113 and the pawl 114 during transportation in the manufacturing process.
In addition, after the cap is opened, the ring of the cap tends to go over the pawl 114 and fall off from the mouth 111.

Abstract

To provide a preform that does not fall during transportation in a manufacturing process and that has a ring that does not easily come off from the mouth after opening. A preform (10) has a mouth (11), a preform body (12), and a flange (13) formed between the mouth (11) and the preform body (12). A male screw part (14) engaged with a female screw part (25) on the inner surface of the cap (20) is formed on the outer periphery of the mouth part (11). On the position between the male thread part (14) and the flange part (13) in the outer periphery of the mouth part (11), a plurality of pawls (15) are provided at predetermined intervals along the circumferential direction, and the pawls ( 15) Engage with the protrusion (28) on the inner surface of the ring (22) of the cap (20) in the circumferential direction to separate the ring (22) from the cap main body (21). Between the ratchet (15) and the flange part (13) in the outer periphery of the mouth (11), there is a groove that is recessed inward than the area between the ratchets (15) throughout the entire circumference of the mouth (11). Circumferential groove (17).

Description

technical field [0001] The present invention relates to a preform having a mouth, a preform main body, and a flange formed between the mouth and the preform main body, and a container made from such a preform, particularly when the cap is opened. A preform and a container that can separate the cap body and the ring at a small rotation angle. Background technique [0002] Conventionally, plastic bottle containers made of PET or the like have been produced by biaxially stretching blow molding preforms (preforms) produced by injection molding. As such preforms, for example, conventionally used Figure 17 A structure as shown (conventional example 1). exist Figure 17 Among them, the preform 100 has a mouth 101 , a preform body 102 and a flange 103 . exist Figure 17 In this case, an annular protrusion (connection portion) 104 is formed over the entire circumference of the mouth portion 101 above the flange portion 103 . [0003] Figure 17 In the illustrated preform 100 (con...
