Embodiment Construction
[0031] Hereinafter, specific embodiments of the cap for containers according to the present invention will be described with reference to the drawings.
[0032] Such as figure 1 As shown, the cap 1 includes: an inner plug 2 fitted to a mouth portion 50a of a container body 50 which is a bottle; The cap 1 and the container main body 50 form a covered container 100 for containing and storing liquid.
[0033] Such as Figure 2a ~ Figure 2c As shown, the inner plug 2 is an integrally molded product made of resin, and includes a separation part 4 , a fitting part 5 and a main body side cylindrical part 6 . Here, the fitting part 5 and the main body side cylindrical part 6 constitute the main body part 20 of the inner plug 2 .
[0034] The separation part 4 of the inner plug 2 is as Figure 2b As shown, there is provided a separating portion side cylindrical portion 4 a that is displaced radially inwardly from the main body side cylindrical portion 6 by the wall thickness of the...

Provided is a container cap capable of reliably avoiding separation between a separation portion of an inner plug and a main body portion even when a shock acts on an upper cap. The cap (1) for the container has an inner plug (2) and an upper cover (3); the holding part (3h) for holding the separation part (4) provided on the inner plug (2) has an annular protrusion ( 8), the annular protrusion (8) extends downward from the lower surface of the upper end wall (3b) of the upper cover (3), and after the separation part (4) is separated from the inner plug (2), the separation part The upper part (4u) of (4) is retained from the periphery; the inner plug (2) has a main body part (20) which is arranged in connection with the separation part (4) at the opening part (OP) and is connected to the container The main body (50) is locked; the separation part (4) has a plurality of protrusions (4p), and the plurality of protrusions (4p) are arranged along the outer periphery of the upper part (4u) and protrude sideways respectively; the protrusions (4p ) is a thin plate in the axial (AX) direction and has flexibility to deform in the axial (AX) direction.
Description
technical field [0001] The present invention relates to a cap for a container provided at the mouth of a bottle-shaped container. Background technique [0002] As a known cap used in a container with a cap, there is a structure (refer to Patent Documents 1 and 2): an inner plug and an upper cap are provided; the inner plug is provided with a body-side cylinder fitted into the opening of the bottle. The shape part and the separation part connected to the upper end through the notch; the upper cover is provided with an annular protruding part capable of holding the periphery of the flange of the separation part by engagement. In the cap of Patent Document 1, the ring-shaped protruding portion is divided into a plurality of protruding elements by slits, and the deformation of the protruding portion or the protruding elements is facilitated, thereby suppressing the impact caused by dropping or the like from above. The cap is transferred to the detachment via the protrusion, pre...
