Abstract

THE INVENTION RELATES TO A SEALED CONTAINER FOR MULTIPLE PURPOSES, PARTICULARLY FOR THE TRANSPORT UNDER AN INERATED OR CONTROLLED ATMOSPHERE OF PERISHABLE MATERIALS, IN WHICH THE GAS CONTAINING AND EXTINGUISHING SYSTEMS OF THE CONTAINER ARE PROVIDED; THIS LATEST INCLUDES A DEVICE FOR INert GAS DELIVERY INSIDE THE CONTAINER, CONSTITUTED BY A GAS SUPPLY SYSTEM, ADVANTABLY CONSTITUTED BY THE TUBULAR FRAME 2 OF CONTAINER 1, THIS SYSTEM BEING CONNECTED TO A PLURALITY OF LATERAL CONDUITS 3 CONNECTED TO REMOVABLE BROADCASTS 4, ARRANGED IN A CENTRAL AREA OF CONTAINER FLOOR 5 AT AN APPROPRIATE DISTANCE FROM THE WALLS OF THE LATTER, IN ORDER TO AVOID THE FORMATION OF PREFERENTIAL PASSAGE AREAS AT THE SAME OF THE CONTAINER WALLS.

Description

The invention is in the field of airtight containers.

  multiple uses. More specifically, it targets

  containers for transportation under atmospheric

  inert or controlled sphere of perishable material, for example-

  full of bulky or bulk powdery products, such as

  agricultural food products.

  In patent FR 2,446,240, descriptions are given of

  This type of waterproofing allows multi-use

  ples, in particular transport under an inert or controlled atmosphere

  controlled by perishable products, said containers having at the end an opening of dimension close to that of the corresponding cross section as well as a door allowing

  sealing said opening. In the con-

  contents of this type, the introduction of an inert gas to an ex-

  end of the container and its outlet at the other end, after ba-

  layering of the ambient gaseous medium, is not carried out

  satisfactory lesson from the fact that zones of passage form

  preferential sage, especially in the vicinity of the walls,

  said zones not allowing to carry out a ri-

  happy with the internal atmosphere of the container. It follows that air which may cause harmful effects on the products to be transported may remain inside

of the container.

  An object of the invention is to obviate this inconvenience.

  deny prior art containers, in reality

  a waterproof container with a diffusion device

  inert gas pre-conditioned inside

  a mass of powdered product loaded in said container

  neur, thereby subtracting the products transported to the ef-

  pernicious effects of ambient air, certain constituents of which, such as oxygen and water vapor, are most often responsible for the degradation of stored products

in the container.

  Another object of the invention is to provide a sealed container provided with the device for diffusing

  aforementioned gases, in which a new conception of the plan-

  expensive container allows the installation of the diffusion device, while eliminating the difficulties of installing a

2 Z 2558 141

  device, difficulties resulting from the presence of passages

  forks which must equip the bottom of the containers

nors.

  The subject of the present invention is therefore a story

  waterproof for multiple uses, especially for transporting perishable materials under an inert or controlled atmosphere,

  which may be in the form of heavy or powdered products

  slow / such agricultural food products, container

  in which admissions systems are provided respectively

  gas and expelling the container, the latter comprises

  both as an inert gas diffusion device inside the container, constituted by a peripheral gas supply system, which is advantageously constituted by the tubular framework of the container, this system being further connected to a plurality of conduits side connected to

  diffusion ramps, wholly or in part, available

  laid in a central area of the container floor at a

  appropriate distance from the walls thereof, so as to avoid

  ter the formation of preferential gas passage zones

  at said walls of the container.

  In a particular embodiment of 1'-

  invention, the side conduits are connected to the right of

  framework tubes and arranged on both sides of the

  kings of the container, each conduit being connected to at least one diffusion ramp. On each ramp are provided a plurality of holes or diffusing bores made in the

upper area of the ramp.

  According to a preferred embodiment of the in-

  vention, the side conduits are formed by drops

  thirds in the container floor and on the

  which are welded waterproof sections, while the diffusion ramps are formed by the extensions of the gutters of the lateral conduits, on which are

  removably mounted profiles pierced with a plura-

  diffusion holes or bores, a regular device

  reader / advantageously constituted by a tube extending

  in the diffusion ramp is provided in the con-

  nection between the lateral conduits and the diffusion ramps

sion, respectively.

  In addition, the respective valves of the systems

  my gas inlet and outlet containers are arranged in one place on a wall of said container, allowing joint sealing of the two valves at customs. Other advantages and features of the

  present invention will appear on reading the description

  following tion of a nonlimiting embodiment, with reference to the accompanying drawings in which:

  Fig. 1 shows in perspective a schematic view

  tick of the container provided with the device for diffusing

gas according to the invention.

  Fig. 2 shows a more detailed top view

  tail of part of the container floor in Figure 1.

  Fig. 3 is a partial sectional view of the plan-

  expensive in Figure 2 along line III-III.

  Fig. 4 is a large cross section

  scale of a diffusion ramp of the invention.

  Fig. 5 is a cross-sectional view at large

  scale of a side gas inlet duct.

  Fig. 6 is a view in longitudinal section through

  part of the connection area between a lateral duct

  and a diffusion ramp according to the invention.

  As shown in Figure 1, the container

  waterproof 1 according to the invention has a general shape pa-

  reelipipedic and its frame 2 consists of tubes

  in hollow profile. At least one long tubular profile

  nal 2a, 2b of the framework at floor level is connected

  thimble by lateral conduits 3 to removable ramps 4

  arranged in a central region of the story floor

  neur, at a certain distance from the walls of the latter,

pictured in Figures 1 and 2.

  In Figures 3, 4 and 5, we can clearly see

  that on the floor 5 of the container are formed drops-

  transverse faces 6. These gutters are covered

  over part of their length by a 6-dimensional profile-

  born so as to come to be embedded in said gutter and

  fix it tightly by welding, thus defining

  side conduits in direct communication with the

2558141q

  tubular yarns of the framework at floor level.

  The central part of the gutters 6 is re-

  covered with a profile of corresponding shape 8 coming there

  press-in detachably. In the upper side

  re of this profile 8, are formed a series of holes or a-

  diffusion injuries. 9 thus defining for each taste-

  face of the profile floor a central diffusion ramp

  if we. In Figure 6 is shown an advantageous connection solution between the lateral conduits 3 and the corresponding diffusion ramps 4. This connection solution consists of a plate 10 axially bored and welded at one end of each lateral conduit 3 and on which comes connect a tube extending

  substantially coaxially inside the diff ramp

corresponding merger 4.

  It will be noted more particularly in FIG. 2 that the gutters 6 are positioned on the floor of

  so as not to hinder them. fork passage areas 12.

  In Figure 1 are also shown in a corner area of a side wall of the container the

  13 inlet and 14 outlet valves of the container gas.

  Such an arrangement is made possible by the use of

  tion of the tubular profile frame 2 of the container

  the invention for the admission and evacuation of said gases.

  Such a provision makes it possible to have to use only one

  single sealing point for these two valves.

  Thus is resolved according to the present invention.

  tionthe problem posed by the existence of preferential passage zones at the level of the walls in the containers of the prior art, and this thanks to the use of tubular frames in hollow profile of the containers in cooperation with diffusion ramps located centrally on the

  container floor, due to a special arrangement

  bottom of the floor with a certain number of

  longitudinal sides which can be covered in their

  central area at a certain distance from the walls,

  corresponding removable yarns pierced with a number

2 2558141

  bores or gas diffusion holes. As a result it becomes easy, thanks to the elimination of passages

  preferential near the walls, to control effectively

  this the internal atmosphere of said containers.

  Although simple holes or bores have been provided in the diffusion ramps, it is clear that

  can also mount any dif-

  fusion in particular of the nozzle, nozzle or venturi type. By ail-

  their, although the waterproof container of the invention has been described with its internal diffusion device as

  having a parallelepiped shape, it is clearly

  tooth it can have any shape, for example cy-

lindrique.
