Container cover

Technical field

The present invention relates to for example to seal the lid of the opening of the container as beverage bottle, more particularly, relate to and have the improvement that shows the container cover of opening bolt resume indication mechanism of opening the bolt resume.

Background technology

Generally, container cover requires to wait and show out bolt by open state failure by rupture before the bolt from lid, opens the bolt resume with proof.This bolt resume indication mechanism of opening is made of the endless belt on the lower edge that is connected on the crown lid main body on the mouth that is screwed together in container via bridging usually, and a plurality of access flap cards that extend from the inboard of this endless belt end on fastener below the container neck.

Open bolt if will cover main body, then endless belt hang over container neck below bridge is disconnected under the state on the fastener, will cover main body and pull down from container, so only endless belt is retained in the below of container neck, is showing and opening the bolt resume.

For example, if be example explanation, then in order to guarantee to cover and the leak tightness that screws togather of the neck thread of container, open-close lid smoothly, lid and the resin manufacture of container by different hardness with the beverage bottle that constitutes by resinous container and resinous lid.But, as described above, remain on the neck of container if after opening bolt, open the endless belt that the bolt resume show usefulness, then endless belt must be removed from bottle during recycling, so become the obstacle of container recycling reclaiming beverage bottle.

Therefore, proposed can be with the lid (with reference to Patent Document 1) that the bolt resume show the endless belt removal of usefulness of opening that remains on the bottle in the past.This covers and be provided with the slit on endless belt, and after Jiang Gai opened bolt, the enough fingers of energy pinched the slit that remains in the endless belt on the container neck and endless belt is removed.But this endless belt is owing to being prerequisite so that endless belt is stayed, so the shortcoming of removing operation, can not carry out the recirculation operation effectively that need carry out endless belt when the recirculation of container is arranged.

On the other hand, the applicant had before proposed not stay endless belt when opening bolt and with the lid (with reference to Patent Document 2) that takes off from container of lid main body.

This lid is provided with otch by the below and constitutes in crown lid main body that upwards has the separate a plurality of shirt rims sheet that forms week and the endless belt that constitutes from a plurality of banded section that each shirt rim sheet of this lid main body extends integratedly, adjacent band shape section is mutually by the bridge combination, each banded section has from its inboard upwardly extending access flap, and this access flap card ends on the raised line ring-type fastener of being located at below the outside face of container neck.

The lid of this structure is because in order to open out bolt and the rotatable cover main body with container, the lid main body rises, when screwing togather of main body and container body covered in releasing, the access flap of each banded section becomes horizontality along the displacement of raised line ring-type fastener, so the banded section of each of ring-type bag is devices spaced apart ground expansion in a circumferential direction mutually, therefore, the bridge that the band shape section is together with each other ruptures, the lid main body further rises, access flap is crossed fastener and sagging downwards, the banded section of each of endless belt with the lid main body be that the state of one takes off from container.

The lid of this structure is owing to take off endless belt from container with the lid main body, thus the operation that does not need to remove endless belt when utilizing again in returnable, so can carry out the recirculation operation effectively.

But, this covers the raised line ring-type fastener of crossing container after opening bolt and the access flap that leaves container hangs down and becomes free state at the peristome of lid main body, internal diameter direction to the lid main body stretches out, so when using this to cover once more closed container, this access flap becomes obstacle and lid can not be screwed on the neck of container.Therefore, on one side must be on one side press inside face be screwed on the neck of container corresponding to the band shape section of access flap with hand push, so the become shortcoming of trouble of the operation of closing cap is arranged.

In addition, the lid of this structure is same with the endless belt of the lid of staying the prior art on the neck of container, has formed a plurality of banded sections like that owing to form endless belt along the complete cycle of the lower edge of lid main body, so need to use wide variety of materials, has lid to become expensive shortcoming.
