Cover device and container for covering built-in valve mounting passage opening in composite type midsize bulk container

Abstract

The invention discloses a cover device and a container for covering a built-in valve mounting passage opening in a composite type midsize bulk container. The container comprises side plates, a base and a passage positioned in the base and used for mounting a built-in valve, the cover device comprises a cover door and a structure or a component used for detachably connecting the cover door with the side plate above the passage, the cover door can be mounted at a position, adjacent to the side plates, on the base, and can rotate along a rotation axis on the cover door to open or cover the passage opening, and the cover door can also be provided with a locking hole and the base can be provided with a lock groove to lock the cover door on the base through a disposable lock. The cover device for covering the built-in valve mounting passage opening in the composite type midsize bulk container is simple in structure and convenient to operate and can well realize dust prevention and / or burgled opening prevention.

Description

Technical field [0001] The invention relates to a container, in particular to the dustproof and anti-tampering of a built-in valve installation passage opening in a composite medium-sized bulk container. Background technique [0002] In the existing composite intermediate bulk container (IBC), the mouth of the valve installation channel for installing the valve at the bottom of the container is generally provided with a cover door. These cover doors can achieve a certain degree of dustproof effect. However, because some existing cover doors fail to cover the entire valve installation passage opening, the dustproof effect is not good. Moreover, the cover door of the passage opening is not connected with other components after being turned over, and the operator needs to operate the valve while supporting the cover door, which is not user-friendly. After the valve operation is completed, the operator needs to manually put the cover door back to the channel opening, which reduces t...

AI Technical Summary

Problems solved by technology

When opening the valve, the operator first tears the middle part of the plastic cover door, and then disengages the buckle from the valve installation channel from both sides, which is extremely inconvenient to operate

Moreover, common tools can be used to disengage the buckles of the plastic cover door from both sides. Due to the plasticity of the plastic itself, the middle part will not be damaged or torn, and the cover door will be removed intact. Plastic cover doors are not very tamper-resistant

Simultaneously, this cover door just cannot be reused, has improved use cost thus

In addition, tearing the plastic cover door may damage the assembly part at the opening of the valve installation channel
