Description

Partially open chemical container insert, in

  The present invention relates to the field of the packaging of chemicals, dangerous or not, in partially open containers, in particular in drums or cakes, and relates to an insert intended for such containers. Packaging of chemicals in

  jerricans or drums causes a number of problems

  my, namely corrosion, cleaning and recycling.

  Indeed, the conditioning of acids can not be

  in metal packaging, requiring the use of

  packaging of plastics or plastics

  In addition, such packagings containing chemicals may not, if they have small openings, be cleaned, as some products harden on their walls. This is particularly the case

  for containers containing isocyanates used

  for the manufacture of polyurethanes.

  In addition, the cleaning of the internal walls of the drums or cans is relatively complicated and expensive, which has a negative impact on the price

cost of the packaged product.

  Finally, in the case where the packaging of

  synthetic or metallic resins can not be

  they can not be recycled and require storage on special landfills, with the risks

  that entails for the environment.

  It has been proposed to obviate these disadvantages by the use of packaging in the form of cans or drums with total opening. In such packages, it is

  possible to use inserts or envelopes made of

  synthetic material, which are placed inside the

  then are filled with product and closed by means of a link or by welding, the packaging being then

  closed by placing a lid.

  However, the full opening drums are very expensive. In addition, this inserter setting technique is not suitable for narrow-necked packages, for example 1 inch or

4 inches.

  The present invention aims to overcome these

disadvantages.

  Its object is indeed an insert for containers for partially open-ended chemicals, in particular for cans or cakes, characterized in that it consists essentially of an envelope

  in the form of a bag of synthetic material, the di-

  are at least equal to those of the container cor-

  respondent, said bag being provided with a sleeve with

the neck of the container.

  The invention will be better understood, thanks to the

  description below, which relates to a method of

  preferred embodiment, given by way of non-limiting example, and explained with reference to the appended schematic drawing, in which: Figure 1 is a side elevational view in section of an insert according to the invention; Figures 2 and 3 are views similar to that of Figure 1 of the insert being placed in a container; FIG. 4 is a view similar to that of

  Figures 1 to 3 showing a container assembly and

  served surmounted by a stopper; FIG. 5 is a partial sectional view,

  larger scale, representing a closure of

  per cap, and FIG. 6 is a view similar to that of the

Figure 5 of a bung closure.

  According to the invention, and as the

  in particular, by way of example, the figures

  1 to 4 of the accompanying drawings, the insert 1 for containers

  2 partially opened chemical products, particularly

  The container for cans or caries is essentially constituted by an envelope 1 in the form of a bag made of synthetic material, the dimensions of which are at least equal to those of the corresponding container 2, said bag being

  provided with a sleeve 3 to the dimensions of the neck 4 of the con-

content 2.

  The plastic bag forming the enve-

  lopper 1 advantageously has a wall thickness

  between 50 mic-rons and 200 microns and is

  killed, preferably in polyethylene or PVC or

polyamide.

  The location of the sleeve 3 on the casing 1 is a function of the location of the neck or orifice

  filling 4 of the carboy or can forming the con-

content 2.

  The preferential use of a polyethylene as constituent material of the casing 1 is due to the flexibility of the polyethylene and the ease of depollution

of the last.

  The container 2 can advantageously be provided

  a second orifice 5, preferably in its upper part

  upper, intended for evacuation of the air from the container

  2 during the placement of the envelope 1.

  According to another characteristic of the invention, the sleeve 3 is returned to the end of the neck or the filling orifice 4 and optionally retracted on the latter or provided with a welded washer 9

  resting on the neck or orifice 4 (Figure 2).

  The closure of the orifice 4 is ensured by a plug 6 screwed onto the end of the orifice 4 (FIG. 5)

  or by a plug 7 screwed into the orifice 4 (Figure 6).

  It is also possible, following another

  characteristic of the invention, to provide the

  of the orifice or neck 4, after insertion and

  possible retraction of the sleeve 3, a lozenge of

  8, the plug 6 is then screwed onto the said orifice 4. In the case of use of a casing 1 with a washer 9, a retraction of the sleeve 3 is not necessary, the screwing of the plug 6 ensuring the sealing

of the envelope 1.

  The insert according to the invention is placed in

  This is as follows: The envelope 1 (FIG. 1) is introduced into the container 2 through its largest orifice 4, then it

  is inflated with air, preferably with hot air.

  The casing 1 is then pressed against the inner walls of the container 2 and the air enclosed by the latter between the casing 1 and its walls is evacuated through the orifice

  4 or by its second orifice 5 forming vent.

  After complete application of the envelope 1 against the inner walls of the container 2, the sleeve 3 protruding outside the orifice 4 is returned to

  the latter and is optionally fixed by thermal retraction or applied by the washer 9 on the neck 4.

  After filling the assembly envelope 1 - container 2 thus obtained, it is possible to provide the original

  fice 4 of a warranty pad 8 before closing by means of a plug 6 (Figure 5). In the case of using a bung 7 for the

  closing the envelope 1 container 2 assembly, the sleeve 3 can also be returned to the upper part

  4 of the orifice 4 is then screwed into the orifice 4.35 Thanks to the invention, it is possible to make packings provided with an insert that can be pulled out. pk after draining the contents and possibly pressurized in order to recover the remainder of product remaining there and which can

  be cleansed by incineration or storage.

  Such an insert requires for its manufacture only a very small weight of synthetic raw material, so that it is of a very low cost and its storage for the purpose of depollution can also

  be done under a very small volume.

  In addition, in the case of

  cineration, the release of harmful products to be treated -is insignificant compared to the clearance obtained in the context of an identical treatment of containers traditionally used. Of course, the invention is not limited to

  embodiment described and shown in the drawings

  nexés Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of equivalent techniques, without leaving

  for all that the field of protection of the invention.
