Description

BONGE SHUTTER

  The present invention relates to a device for

  closure or shutter of metal or material drain

  re plastic with means for fixing accessories, in particular for fixing a tap or

  weeper or barrel cinnamon or barrel.

  This type of plug closure system is mainly used when the potential user is not supposed to have the necessary accessories for the metered sampling of the liquid content of a barrel or

  barrel. For example, a small consumer (normal household

  bad), or even a large consumer working in difficult organizational conditions, are not supposed to have at all times and immediately a tap or a cinnamon or chantepleur intact and adapted to the

  barrel or barrel in question. The corresponding accessories

  for the opening of the barrel and for the sampling

  dried liquid product, including cinnamon or sing

  are crying, have so far been supplied either separately or in a plastic bag and attached to the drain closure by a string. However, it turned out that this accessory fixed in this way during transport was easily lost or was frequently stolen. In addition, in particular

  in the case of toxic chemicals, it is

  particularly important to provide cinnamon or chan-

  tepleure adapted to liquid products and working perfectly. We know, for example, closure or closure systems for plugs for filling bungs.

  large diameter, in principle 50 mm on which we screw

  is directly a cinnamon for the bung of sampling or piercing of a diameter in principle of 19 mm and which for transport are assembled in such a way that the cinnamon protrudes inside the barrel or barrel and -2-

  therefore cannot be lost or stolen.

  The user must then open the shutter system

  50 mm bung before detaching the cinnamon from the system

  closing valve and mount it in the drain. These overflow closure devices

  rant the intact arrival of cinnamon at home

reader.

  However, a major drawback of this com-.

  binaison constituted by cinnamon back-screwed and the bung closure device resides in that the cinnamon is each time wetted by the liquid contained in the barrel and can during the installation of the cinnamon due to contamination sometimes give rise to otherwise dangerous manipulations, always

unpleasant.

  An object of the present invention therefore consists in developing an accessory or device making it possible to transport the accessory or closing device jointly with the barrel and preventing it from being

  contaminated with the content of the latter.

  An object of the present invention consists in particular of

  protect the accessory from the risk of loss and damage. This object is achieved according to the invention thanks to a

  drain closure device which is characterized er.

  what it presents a part in the form of bag or cou-

  shovel protruding inside the barrel or barrel,

  and forms a sufficiently large recess to

  see receive totally and safely access-

evening inside.

  Thanks to the plug closure device according to

  the invention, it will be possible without particular expenses

  give in to a shipment that guarantees cleanliness and without risk

  loss and deterioration of the accessory of '

  barrel plug closure fixed on the latter and no-

  greatly simplify assembly or disassembly, and this in - 3 -

cleanliness conditions.

  In a first preferred embodiment, this part has structures making it possible to fix the accessory inside and in particular on retaining elements. These retaining elements prevent the loss or simply theft of the accessory during the transport of the barrel. These fixing elements notably prevent deterioration of the accessory during transport. In a second preferred embodiment, the depression or recess has a cover. In this way, the accessory is protected from the outside against

  risks of loss and contamination.

  In a further variant of this preferred embodiment, there is also provided on the cover

  inside the recess or depression of the structures

  res for fixing the accessory.

  In a preferred additional variant, the

  fastening structures have elastic elements

  ques facilitating the withdrawal when opening the lid. Among the preferred features of the closure system according to the invention, the following may be indicated:

  - the part shaped in the form of a pre-

  feel structures which are formed by deformed

  mations, special configurations or related elements

  worn, making it possible in particular to secure the accessory, - the structures form a threaded, pluggable or flangable attachment, - the shaped part is provided with a cover,

  - the part shaped like a bag is presented

te in the form of a sheet,

  - the cover is of the tearable type, folded down

  ble, screw or bowl and it consists of a sheet, -4- - the shaped part of the bowl are

  moreover provided with elastic elements facilitating the ex-

  traction of the accessory, - the covering has deformations or added elements, making it possible in particular to keep the device in place,
