ITRM20140119U1 - PALLETIZED CONTAINER WITH FORCED DELIVERY SYSTEM OF CONTENT STORED IN A BAG MADE IN SEALABLE PLASTIC MATERIAL STORED INSIDE THE SAME CONTAINER - Google Patents

Description

DESCRIPTION

"Palletized container with forced dispensing system of the contents stored in a bag made of sealable plastic material housed inside the container itself"

SUMMARY:

The container object of the present application is aimed at preserving and autonomously dispensing pasty fluids, high viscosity liquids or even fine powders and making them available to the user in the absence of additional dispensing equipment or systems. It has the shape of a square parallelepiped with a pyramidal bottom, equipped with a load-bearing and palletized structure and made of stainless steel and carbon steel.

The container is equipped with an autonomous pneumatic or electric piston pump, directly connected to the drain.

Inside there is a plastic bag also in the shape of a rectangular parallelepiped whose inlet neck can be sealed in order to keep the content in an artificial atmosphere (for example inert gas) and / or to be emptied of the air for the vacuum preservation of the contents.

The container can be reused for the same product several times or, with limited and quick maintenance, it will be clean and usable for a different product.

Unlike existing containers on the market in the sector of paints, inks, adhesives and pastes in general, this container delivers the content autonomously and at the same time preserves the content in a pre-ordered atmosphere (for example inert gas or even vacuum), the latter being inside the sealed bag and which collapses as the contents are dispensed.

In the state of the art, the containers used in the aforementioned sectors, which also have autonomous dispensing equipment, do not have the possibility of keeping the contents in an artificial atmosphere or under vacuum; on the contrary, those used that can also boast preservation systems from contact with the air of the contents are not equipped with a system for forced and autonomous dispensing by means of a piston pump.

The pump is made up of two distinct parts that can be separated without the use of tools (the motor is screwed / coupled to the piston pumping body), it allows the use of a single motor on various containers, considerably reducing the cost of multiple containers intended for same user.

The user can in fact disassemble the motor from the emptied container and install it on the new container, quickly, independently and without tools.

DESCRIPTION

The container object of this application is made up of the following elements / parts (as highlighted in the Main Drawing):

1) Supporting structure in carbon steel that makes the container palletized, stackable with others of the same type and size.

2) Stainless steel container made of stainless steel and composed of:

to. Interlocking lid with closing hook

b. Body in the shape of a square or rectangle parallelepiped

c. Inverted pyramid shaped bottom

d. Flange welded on top of! bottom

3) Second internal container made of plastic material (also referred to below as: "bag") and made by:

to. Top fill neck

b. Body in the shape of a square or rectangle parallelepiped

c. Loops on the upper and lower sides for housing the frame d. Plastic flange on the lower outlet hole

4) Removable frame made up of steel tubes connected together by means of quick pressure couplings.

5) Elastic (or spring) hooks for retaining the frame

6) Piston pump

7) Pneumatic (or electric) motor with quick coupling

8) Counter-flange with three-way outlet fitting installed on

The container, thus created, is aimed at achieving many purposes described below at the same time:

- Reduce the economic burden of packaging polluting materials in general to the producer / packager of the product and which must be stored in an artificial atmosphere, otherwise the desired characteristics will decay (for example due to oxidation with air / oxygen etc.)

- Reduce the environmental impact in general and economically by reusing the same container several times which, for this purpose, returns to the manufacturer / packer to be eventually filled with the same product.

Allowing the use of the container for different products through fast and economical maintenance, i.e. by changing the bag and replacing and cleaning up the outlet fitting and the pumping part.

- Provide the user with a single container, to be returned to the supplier at the end of the emptying, thus eliminating the burden of expensive disposal of the usual smaller containers.

- Carry out the dispensing of the product independently, ie without specific equipment and / or systems, specifically when tapping by simple gravity is not sufficient or suited to the needs of the user.

- Obtain the delivery of the content even at several meters away from the container, in the place of actual application of the product also placed at a different height.

- Preserve the contents from contact with the air even during the emptying of the contents, especially if partial and interrupted and then resumed.

- Be manageable, safe and economical for transport and storage purposes, even outdoors., Thanks to the possibility of stacking multiple containers.

The sector of application for which the container appears to be the optimal response to all the aforementioned needs is that of supplying products and which, by their nature and / or by modifications induced in the production process, react with the air, irreversibly changing the their state and chemical / physical characteristics in the time of contact with the environment.

Among these it is enough to mention the inks and varnishes for offset and letterpress printing, conventional and UV, paints in general, plaster pastes and adhesives used in the construction sector, cold glues in general, resins and, last but not least, many food raw materials (honey, jams, vegetable fats etc. etc.).

In practice, the container is intended for all materials which react to contact with air and which are used in significant daily quantities.

In practice, the products that, in the absence of large containers (i.e.> 200 KG) that can guarantee autonomous delivery and simultaneous correct storage during transport / storage / use, are traded in cans, in buckets to be handled and dosed / empty / spatulate manually and which after use become waste destined for expensive disposal.

Similarly, the products now supplied in non-returnable drums (i.e. 200 KG) which are sometimes used with external pumping systems and which therefore see the investment by the user relegated to that specific product / raw material.

Some containers are also returnable for subsequent reuse, however they are not equipped with an autonomous and forced dispensing device.

Or, those equipped with a forced delivery system do not keep the content in a specific atmosphere (or vacuum).

Those that have a similar storage system, i.e. a sealable bag, are not equipped with an integrated piston pump and the plastic inner bag has no sides held taut and the others fold like a gusset as it is in this container. Therefore, in the case of viscous and adhesive products, they do not allow correct emptying; in fact, the “unguided” bags usually collapse and are therefore dragged by the contents themselves until they obstruct the outlet hole, preventing complete emptying.

In this container, the purpose of avoiding the above, the inner bag of this container is made with several measures:

a) It is made of plastic material with a relatively high thickness, i.e.> 0.25 mm and has the shape of a rectangular parallelepiped (or square depending on the volume of the container)

b) The upper and lower sides equipped with special "loops" welded externally on which it is easy to assemble the removable metal frame

c) The vertical sides are pre-formed to be able to fold "bellows" and then collapse without obstructing the outlet hole and thus favoring the approach of only the horizontal sides held taut by the frame.

A further precaution used in this container, aimed at maximum emptying in the presence of viscous fluids and with adhesiveness, is to be able to keep the upper frame of the bag connected to the upper edge of the metal container using hooks equipped with elastic (or springs).

This expedient is useful in cases of emptying very viscous pastes in a relatively short time; in fact it helps to retain and keep two sides raised (upper and lower) intended to mate while the vertical sides take the correct form of "bellows" folding

The force exerted by the springs (or elastic bands) is variable on the basis of the “fluidity” characteristics of the content and also depending on the desired emptying speed.

The holding force is minimal and sufficient to be overcome by the depression created by emptying the contents.

This type of container can be made in various volumes, from a few tens to several hundred liters, to adapt to the various commercial standards already in use.

The container is made of metal and is equipped with a metal flange fixed on the bottom in the shape of an inverted pyramid.

This flange will house the plastic flange, integral with the bag and which is also the outlet hole of the bag itself.

The metal counter-flange that houses the three-way fitting, since it is coupled to the flange of the container, crushes the plastic flange thus creating the sealing gasket to isolate the contents of the bag from the metal container.

The outlet fitting has three independent ways (see main drawing)

• Straight sleeve with end thread with female plug.

• Horizontal threaded sleeve, for coupling the pumping body

• Horizontal threaded sleeve, for tap / ball valve

The vertical sleeve is useful for cleaning the sleeve itself or for rapid emptying by gravity.

The horizontal sleeves are intended for the pump and any tap.

The presence of a tap also allows the connection of different pumping equipment.

This is particularly useful to the content provider; in fact, if the first filling by the manufacturer can be done directly from above (through the upper "neck" of the bag), the subsequent ones to keep the bag sealed are made by pumping the product from the outlet fitting that will swell the bag up to the volume necessary. This practice, however, in addition to reducing human intervention, would allow the residual content to continue to remain in optimal conditions (eg vacuum) even for the time necessary for the new filling phase.
