Composite medium-sized bulk container anti-theft device and its sliding anti-theft cover

Abstract

The invention relates to a composite intermediate bulk container antitheft device and a slipping-type antitheft cover thereof. The slipping-type antitheft cover comprises an annular shell. The annular shell is provided with a large end and a small end. Fastening hooks extend from the large end of the annular shell. The annular shell is provided with a tearing handle. The tearing handle fills the opening of the annular shell and is connected with at least one side of the opening of the annular shell through a tearing line. The slipping-type antitheft cover disclosed by the invention has the advantages that the antitheft cover is convenient to operate, the intentional calibration is not required, the blind operation can be realized, the cover can be easily fastened on a valve cover, the working efficiency is improved, the antitheft cover is convenient to open, the falling of excessive parts does not exist, the environment is not affected, the antitheft cover cannot be restored after theantitheft cover is damaged, the antitheft effect is good and the valve cover can be repetitively used.

Description

technical field [0001] The present invention relates to an anti-theft device for a composite intermediate bulk container (IBC), in particular to an anti-theft cover, which is installed on the valve cover of a composite intermediate bulk container (IBC) to prevent the valve cover from being opened, thereby preventing the contents of the container from being opened. stolen. Background technique [0002] Composite intermediate bulk container (IBC) is a kind of packaging turnover container widely used in food, biochemical, pharmaceutical, chemical and other industries in the world. Since the IBC container can be reused many times, it has obvious advantages in filling, storage and transportation, and compared with the round drum, the IBC container can save 35% of the storage space, and the size meets the ISO standard. It is not only suitable for aseptic canning, but also has a compact box body, which is convenient for safe and efficient storage of large quantities, so it is wide...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a DN50 butterfly valve in the European market that is widely used as the IBC discharge valve. Its structural features are shown in the patent WO 2007 / 030052A1. Or there are corresponding binding holes on the valve body, and then use a binding strip to pass through the hole on the valve cover and the valve body or the handle and bind the two to achieve the purpose of locking the valve cover and preventing the cover from being unscrewed. The disadvantage is that compared to such a bulky container of IBC (such as the plastic folding IBC mentioned in PCT patent WO 01 / 47780A1), the operator tries to pass the anti-theft strapping strip through the valve cover and the corresponding handle or valve in such a narrow bottom valve recess The binding holes on the body are very difficult to operate, the efficiency is very low, and it is not humanized. If you try to untie the binding, you need to use tools, which brings inconvenience to the operator.

[0004] Some valves are equipped with anti-theft strips in addition, such as a kind of plastic anti-theft cover announced on the Chinese patent (authorized publication number is CN2640951Y), which includes anti-theft strips and screw caps, and the screw caps are provided with a protrusion on the container mouth. Interlocking meshing protrusions, the inner side of the anti-theft strip is densely covered with tooth pieces, and the tooth pieces are stuck on the bottle mouth. The anti-theft strip is connected with the screw cap through small plastic pieces evenly distributed around the anti-theft strip. The outer side of the cover is flat, and the small plastic sheet is located in the narrow gap between the upper screw cap and the lower anti-theft strip. The disadvantage of the above technology is that when the container is sealed by the screw cap with the anti-theft strip, tools or larger tools are required. Only by destroying the anti-theft strip with a lot of strength can the locked state be released; the above-mentioned anti-theft cover is relatively weak due to the combination of the cover body and the anti-theft strip. Before it is installed on the valve, the anti-theft cover is easily damaged due to accidental bumps, which increases the scrap rate. ;The valve cover with this structure is added, which puts forward higher requirements on the manufacturing process and production cost; the cover and the anti-theft strip are integrated, and the cover cannot be used again after tearing the anti-theft strip and separating it from the cover ;This design not only leads to waste of materials, but also makes it difficult to clean the working environment because the anti-theft strip is easy to fall on the ground after it is detached from the cover
