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

The present invention provides a preformed product which does not fall in the conveying of manufacturing process and has a ring that does not easily fall off from an opening after being opened. The preformed product (10) is provided with the opening (11), a preformed product body (12) and a flange part (13) which is formed between the opening (11) and the preformed product body (12). The periphery of the opening (11) is formed with a male thread part (14) on a female thread part (25) clamped on the inner surface of a cap (20). A plurality of pawls (15) are installed with a preset interval along a circumferential direction on a position between the male thread part (14) and the flange part (13) in the periphery of the opening (11). The pawls (15) are clamped at a projection (28) on the inner surface of the ring (22) of the cap (20) thereby disconnecting the ring (22) from the cap body (21). A circumferential slot part (17) which dents inwards more than the area between the pawls (15) throughout the periphery of the opening (11) is installed between the pawls (15) and the flange part (13) in the periphery of the opening (11).

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...
