Definitions

  • the present invention refers to a container for packaging that is particularly indicated for containing medicines, substances, products or foods that need to be protected and insulated from the surrounding environment and maintained within a constant temperature range for a certain number of hours during their transport.
  • temperature changes can, together with humidity, through the condensation which is formed, corrode the protective film of drugs, powdered products can congeal, damaging the product, while liquid formulations undergo separation of the components with the formation of precipitates, so they must be disposed of with subsequent disposal costs and waste of material.
  • drugs must also be protected from the light and impacts from the external environment so that the packaging and preparations are not damaged or altered, as their preparation is very expensive and also their disposal would be particularly onerous, as they are highly-polluting products.
  • the first one uses a polystyrene container that has a second contanier above it, in turn closed with a lid, inside which dry ice is placed.
  • a polystyrene container that has a second contanier above it, in turn closed with a lid, inside which dry ice is placed.
  • inside the container with the dry ice there are some indentations that, during use while the drugs are being placed in the boxes, are manually pierced by an operator to allow the cold air to pass through to the underlying container with the drugs inside.
  • the described container also has some disadvantages.
  • Another system for the transport and conservation of drugs involves another polystyrene container inside which the drug packs, together with 'gel ice packs' to maintain them at the right temperature, are placed.
  • the 'gel ice packs' are containers with chemical substances inside that can release the cold air gradually allowing the environment inside the container to be more or less maintained constant for a small amount of time and with temperatures no lower than 8°-10° C.
  • the container In the containers, above the drug packs, there are small air cushions to fill the remaining space and keep the packs themselves still.
  • the container is then closed with a lid and sealed using adhesive tape that closes the slit between the container and the lid.
  • the first disadvantage emerges from the fact that the 'gel ice packs' require a place where they can be refrigerated before use, with the need for spacious freezers that at least 12 hours before are filled with the 'gel ice packs' that will then be used for the preparation of the containers with considerable encumbrance in accommodating the freezers and consumption of electricity for them to function, besides the fact that the 'gel ice packs' then have a temperature of only a few degrees below zero, so are therefore not sufficient to maintain the drugs in the temperature range required for their correct conservation.
  • a second disadvantage found with the 'gel ice packs' is that, inside the container, they occupy a fair amount of space that could otherwise be used to contain other drug packs and they are also quite heavy.
  • a further disadvantage emerges from the fact that the operator must inflate the air cushions using special equipment and then place them in the containers to fill the remaining space with longer preparation time of the container and further costs for materials besides the further materials that must then be disposed of.
  • the container possesses a chamber intended to be able to contain products to be transported in a refrigerated manner.
  • the chamber is closed by a wall on which a chilling charge is located.
  • the charge consists of carbon dioxide in the form of snow or ice and it is incorporated in a permeable envelope.
  • the container comprises a cover to close it.
  • the aforesaid container does not allow the products contained therein to be held firmly in place during transport.
  • the chilling charge requires a place in which it can undergo preparation and refrigeration prior to its use.
  • the chilling charge does not allow the temperature inside the container to be monitored and controlled since it is able to provide some refrigeration for the products but it is not possible to calculate for how long and what temperature and, above all, if the temperature obtained remains constant over time and for how long.
  • the container is not hermetically sealed, which means it is easily opened and therefore there is no guarantee for the end user that the product contained therein will reach destination intact and correctly preserved.
  • the containers are, in the first case, voluminous and cumbersome and, in the second, with a reduced capacity due to the 'gel ice packs' inside, there is a considerable waste of space during transport and a greater use of materials with subsequent production costs, besides the fact that they have encountered numerous problems, above all concerning the maintenance of the necessary temperature for the conservation of the drugs for at least 36 hours.
  • the aim of the present invention is substantially to solve the problems posed by the known techniques, overcoming the difficulties described above by realising a container for packaging that is able to maintain a pre-established temperature for long periods of time inside it, without the presence of pollutants and encumbrance and with low final volumetric dimensions and reduced weight.
  • a second aim of the present invention is to realise a container for packaging that is able to properly hold the products contained inside so that, during transport, they cannot move and become damaged, along with the products contained in them.
  • a third aim of the present invention is to realise a container for packaging that has an optimal hermetically sealed lid and allows the final user to have the certainty that the container has not been opened during transport.
  • Another aim of the present invention is to realise a container for packaging and procedure therefor that makes the packaging stages quick and simple and that is able to perfectly accommodate any type of product without losing its characteristics of practicality, sealing and safety.
  • Another aim of the present invention is to make available a simple and practical container for packaging that does not place the packs contained inside in contact with the refrigerating components.
  • a further aim of the present invention derives from the fact that the container for packaging and its components can be completely re-used or recycled.
  • the last but not least important aim of the present invention is to realise a container for packaging and procedure therefor that is simple to manufacture and that functions well.
  • FIG. 1 With reference to the said figures, and in particular figure 1 , with 1 a container for packaging has been indicated overall, according to the present invention that can be used to achieve the packaging process in question and contain drug packs that must be transported maintaining them at a constant temperature for at least 48 hours.

  • each lateral projection 63 has a bevelling 63a near the rear edge to allow better entry and sliding inside the respective groove 41. Furthermore, also the projection 62 has slightly bevelled corners by means of bevelling 62a.
  • the closing element 6 on the closing wall 61 is endowed with at least one indentation 64 designed to allow an easy grip of the element itself to allow its movement and sliding for the opening and closing of the lid.
  • the indentation 64 may be present in the front portion 60.
  • the covering wall 61 of the closing element 6 there are instructions, which are engraved or printed, that indicate the necessary operations to be carried out for the opening and the opening direction of the covering wall.
  • each lateral groove 41 there is a plurality of teeth 45 that serves to couple and bind with the corresponding second teeth 66 located on the upper edge of the projection 63 as shown in figure 4 .
  • each lateral groove 41 there is a plurality of projecting parts 45 that serves to couple and bind with the corresponding slots 66 located on the upper side of the projection 63.
  • the projecting parts and the slots stop the lid from sliding and therefore the container can be opened.
  • a variation has saw teeth to keep the lid equally effective.
  • the front wall 5 is internally provided with a niche 51, designed to accommodate a plate 7 that in section is a T-shape so that it can be inserted into the niche 51 from top to bottom and cannot come out inside the container.
  • a coupling element 8 is attached irremovably, which is designed to block a valve 9, in turn, designed to block an inflatable element 10.
  • the valve 9 is essentially composed of a body 90, which is hollow, with a small opening 91 at one end and binding means 92 at the other end designed to connect to a terminal section 93 of the body 90.
  • the binding means 92 are composed of a thread or notch coupling.
  • closing means 94 designed to rest against the terminal wall of the body in order to obstruct the small opening 91.
  • a small rubber ring 94a for a better seal.
  • a thin rope 95 which protrudes from a hole present in the terminal section 93 and is designed to insert into a slit 70 to be held in an eyelet 71 present in the plate 7.
  • a spring 96 designed to rest against the closing means 94 with one end, and against the terminal section 93 with the other end, in order to keep the closing means against the opening 91, closing it.
  • the inflatable element 10 to the body 90 of the valve is attached the inflatable element 10 by means of a joint 97 being of an L-shape in order to be perpendicular to the valve itself, so that the inflatable element 10 may expand easily inside the container in the space to be filled.
  • the joint 97 is attached to the valve 9 by means of rapid coupling, for example, bayonet type with a rubber blocking and sealing ring 98 and also the coupling is of a forced type so that the joint is positioned horizontally for the correct expansion of the inflatable element.
  • rapid coupling for example, bayonet type with a rubber blocking and sealing ring 98 and also the coupling is of a forced type so that the joint is positioned horizontally for the correct expansion of the inflatable element.
  • the inflatable element 10 is composed of a small balloon in expandable material, such as latex or a bag made of plastic. Furthermore, the inflatable element 10 is designed to contain a pre-determined quantity of dry ice 11, as shown in figure 3 .
  • the front wall 5 is endowed with an opening 52 located near the terminal part of the valve designed to accommodate the thin rope 95 inside, with a possible gripping element such as, for example, a small ring.
  • a possible gripping element such as, for example, a small ring.
  • a variation of the container in question does not have the niche 51 or the plate 7 but the coupling element 8 is directly attached to the inside of the front wall.
  • a second variation includes a pair of coupling points on the body 90 of the valve that is designed to insert into the front wall 5.
  • the container 1 has the base wall 2 that is endowed with a plurality of very small pyramids, as shown in figure 6 , or other projections with different conformations, to create a corrugated floor in order to be able to reduce to a minimum the contact surface of the packs on the floor of the container and keep the packs themselves slightly raised, so allowing good circulation of cold air and allowing the deposition of any condensation on the bottom without it damaging the packs.
  • the lateral and rear walls have a plurality of vertical ribs having the same aim as described for the pyramids. In this way the product or the packs do not come into contact the walls of the container as they only touch the points.

  • the body 90 with the inflatable element 10 is inserted irremovably into the opening of the recess 51 of the container.
  • the body 90 is endowed with a rubber ring that seals it to the container and functions as a barrier against any release of cold air from the container through the opening.
  • the body 90 of the valve has a configuration in sectors with at least three cylindrical portions 90a, 90b and 90c, each of which are endowed with a diameter that is smaller than the previous one.
  • the valve 9 has, inside the body 90, an internal unit 92 that serves as an insulating chamber and is basically composed of a first cylindrical section 92a and a second section 92b which is also cylindrical but with a smaller diameter. Between the first 92a and the second section 92b the unit 92 is composed of a rubber sealing ring 93 designed to rest against the upper edge of the second cylindrical portion 90b in order to remove any possibility of contact between the body 90 and the internal unit 92 so making the valve hermetic.
  • the internal unit 92 is hollow and functions as an air chamber that insulates, so as not to let cold air pass out of the container or warm air inside.
  • the internal unit 92 at the top has a small groove 94 and two overhangs 94a diametrically opposed to each other that are designed to insert respectively into the housings 96 and attach to the body 90 the internal unit 92.
  • the internal unit 92 at the bottom has a first projection 92c in the centre of which is a second projection 92d. Each projection is designed to attach to a corresponding spring: 21 and 22 respectively.

  • the inflatable element 10 is designed to hold a pre-determined quantity of dry ice 11 that is pre-measured depending on the dimensions of the container and the desired refrigeration time.
  • the container 1 includes a diaphragm 12 that is basically composed of a plate 12a endowed with a lateral edge 12b that has corners cut to 45° so that the edge portions can be slightly widened towards the outside, as shown in figure 8 .
  • the external lateral surfaces of both the upper wall 12a and the lateral edge 12b may have an undulated profile so as to create a plurality of small vertical canals while the upper surface of the wall 12a has at least one indentation 12c to be able to move the diaphragm inside the container and extract it from the well 8.
  • the diaphragm 12 is designed to close the well 8 inside which the inflatable element 10 is housed.
  • the thickness of the upper wall 12a depends on the refrigeration time that is desired, in fact, the greater the thickness the longer the container maintains the desired refrigeration temperature. In more detail, with a greater thickness better insulation of the well is achieved so the dry ice contained in the inflatable element 10 sublimates more slowly and, as a result, the source of cold air lasts longer.
  • the second shutter 98 is joined to the internal unit 92 by the spring 22 which is set at a pre-established pressure that allows the balloon to inflate and the diaphragm 12 to lift up before allowing the second shutter 98 to lift up and let the gas produced by the sublimation of the dry ice to escape reducing the pressure inside the balloon.
  • the first shutter 97 can move in turn and let the gas from the balloon escape but in this case the spring 21 is set to a higher pressure compared to the spring 22 so if the second shutter does not work the first one intervenes.
  • the gas that is released from the balloon escapes from the valve through the holes 95 of which there are four in the present embodiment.
  • any gas that escapes from the balloon and then from the valve stays inside the well 8 and is not released outside the container.
  • the container for packaging according the present invention includes a foam septum 13 that is designed to be placed on top of the packs, as shown in figure 9 , in order to create a protective cushion for the packs that absorbs the pushing force from the diaphragm and absorbs any condensation formed inside the container so that the packs remain in perfect condition.
  • a variation of the container 1 involves the upper surface of the diaphragm 12 being provided with a plurality of very small pyramids or other projections with different conformations so as to create a corrugated base in order to be able to reduce to a minimum the contact surface of the packs on the surface of the diaphragm and keep them slightly raised so allowing good circulation of cold air and allowing the deposition of any condensation on the surface without being able to damage the packs.
  • the vertical walls have a plurality of vertical ribs that have the same aims as described for the pyramids. In this way the product or the packs do not come into contact with the walls of the container as they only touch the points.
  • the container 1 is preferably produced in polystyrene but can also be produced in polypropylene or in any case any other material with insulating properties.
  • the container has a valve sealing film near the recess 51 for which the container can be ensured to be safe as the final user has the guarantee that the container has not been opened or tampered with.
  • the container may be endowed with a label complete with a code with which all the movements of the container can be followed.
  • the containers can be stacked on top of each other thanks to feet 18 on the base and small depressions 19 on the closing element designed to accommodate the feet of another container in a way that is substantially known.

  • the base is produced in aluminium or any other material that meets the said requirement.
  • under the base there can be a foundation composed of a small air chamber that creates further insulation.
  • valve 9 is produced in plastic by means of moulding.
  • a further variation of the container in question involves the diaphragm being positioned above the drug packs that are placed at the bottom of the container after having positioned the foam septum.
  • the inflatable element on expanding exercises a pushing action on the diaphragm towards the bottom in this way holding the packs still and, at the same time, it pushes upwards and keeps the closing element blocked.

  • the container 1, according to the present invention is designed to be operated from when not in use when it is inactive, no products being accommodated in the container, to a first operative state in which the container, after the introduction of the packs on top of the diaphragm and the foam septum, is closed using the closing element, in the inflatable element, through the body of the valve, dry ice cylinders are inserted and in the body the internal unit 92 with the overhangs 94a are inserted, which slot together in the housings 96 and to a second operative state in which the dry ice sublimates enlarging the inflatable element that fills the remaining empty space inside the well, making the diaphragm lift up blocking the packs and the closing element.
  • a different embodiment could involve the use of another simpler valve structure, which may already be present on the market and would therefore probably be less expensive than the ones described.
  • the valve necessary for the container must be able to easily release the gas contained in the inflatable element.
  • An example: a uni-directional type valve or a "clagest" valve could be used which are substantially known.
  • a user When transporting products that need to be maintained at a certain temperature and for a certain number of hours such as, drugs for example, a user only has to take the container structure and place the drugs inside. When this has been carried out, the user must take a plate 7 to which a valve 9 is attached and apply an inflatable element 10 that contains a certain amount of dry ice depending on the temperature that must be obtained and the time for which the products must be maintained at such a temperature, and insert it in the corresponding niche, passing the thin rope through a slit located on the front wall 5, and inserting it into the opening 52.
  • the container is basically ready to be transported as the dry ice has already started to sublimate, transforming into gas that inflates the inflatable element which will then occupy all the spaces that are still empty inside the container, as shown in figure 3 .
  • the sublimation of the ice also serves to maintain inside the container a temperature range that allows the perfect conservation of the drugs contained in it for many hours.
  • the valve is activated releasing some of the gas produced from the inflatable element and letting it escape inside the container.
  • the pressure of the gas produced, present in the inflatable element overcomes the resistance of the spring making the closing elements move to open the small opening 91 and let the gas escape from the hole provided in the terminal section 93.
  • the container is supplied already provided with the valve attached to the internal front wall so the operator, after having placed the products inside the structure, only has to attach to the body of the valve the joint with the inflatable clement that has been previously prepared with the dry ice inside.
  • the inflatable element When the inflatable element is attached to the valve, the said inflatable element starts to expand, as the gas produced by the dry ice is no longer released into the environment.
  • a user only has to place the drug packs into a container, placing them on top of the diaphragm and, once this has been carried out, place the foam septum on top of the packs and close the container by positioning the closing element so that the lateral projections slide into the corresponding grooves until resting against the rear wall and the rear projection is housed in the relative groove 31.
  • the operator just has to take the container structure, position it with the front wall facing upwards and insert the dry ice, through the body of the valve, so that it enters the inflatable element.
  • the internal unit must be inserted into the body of the valve, the groove rotated until the overhangs on the unit insert into the housings of the valve body and pressing slightly downwards rotate the groove further until the overhangs cannot be moved.
  • the container is basically ready for transport as the dry ice has already started to sublimate, transforming into gas that inflates the inflatable element which then occupies all the space inside the well and, once this space has been occupied, starts to lift up the diaphragm, the edges of which enlarging under the pushing force from the inflatable element create friction against the vertical walls reducing the space available.
  • the sublimation of the dry ice serves, other than to make the diaphragm lift up, to keep the packs in position and maintain a basically constant temperature inside the container to allow a perfect conservation of the drugs contained for the necessary time.
  • the valve is activated releasing some of the gas produced from the inflatable element and letting it escape into the well.
  • the pressure of the gas produced, present in the inflatable element overcomes the resistance of the spring 22 making the second shutter move to open the passage between the first and the second shutter and let the gas escape from the holes 95 in the well.
  • the gas can still be released in the way provided for by the type of valve present.
  • the container is supplied already provided with the valve body attached to the internal front wall so the operator, after having placed the products inside the structure, only has to insert the dry ice and couple the internal unit with the valve body.
  • the present invention therefore achieves the proposed aims.
  • the container for packaging in question is able to maintain a constant and pre-established temperature range inside it for long periods.
  • the presence of the dry ice allows much lower temperatures to be obtained, compared to the use of the 'gel ice packs' of the commonly known systems or for much longer periods of safety with much higher safety margins (up to 48 hours with temperatures from 2° to 8° Centigrade).
  • the duration of the temperature depends solely on the quantity of dry ice inserted into the inflatable element.
  • the container has a low voluminous encumbrance and reduced weight compared to the commonly known containers.
  • the container according to the present invention using the inflatable element allows, through the expansion of the gas, to provide for three requirements at the same time: cooling to maintain a constant temperature range and for a certain time period such that to conserve the container contents in the optimal way, filling the remaining space inside the container in order to keep the products inside still and blocking the closing element thereby avoiding the need for the presence and use of adhesive tape.
  • the internal blocking of the closing element offers the final user the possibility to check that during transport operations the container has not been tampered with or opened with the risk of damage to the products contained inside or theft and that it has arrived at its destination in the same conditions in which it left, provided that the polystyrene membrane that closes the opening or the valve protective film is intact.
  • the fact that the polystyrene membrane on the front wall, near the opening, or that the valve protective film on the front wall, near the recess, are intact, during transport, is tantamount to having a safety guarantee seal as this guarantees that the container has not been opened.
  • the inflatable element may have writing or slogans on it to act as an advertising medium.
  • the container for packaging can be prepared by unskilled operators quickly and efficiently, unlike the commonly known techniques. Furthermore, with the packaging procedure according to the present invention it is possible to prepare the containers quickly and easily and without the necessity to prepare the coolants many hours beforehand, as for the 'gel ice packs', or have equipment available to fill the air cushions.
  • the container is very versatile and can be adapted perfectly to any type of product to be conserved and transported without losing its practical characteristics.
  • a further advantage of this container is due to the fact that it has low production costs and can be completely re-used or recycled with considerable savings in terms of disposal of pollutants, unlike with the commonly known containers.
  • the plate and valve can be completely re-used and the container can be retrieved and transformed so there are no materials to be disposed of with subsequent savings in management costs.
  • the container according to the present invention has smaller dimensions so it is less cumbersome and heavy, and so allows savings in transport costs, as a higher number of containers can be loaded onto a lorry.
  • the last but not least important advantage of the present invention is that it is extremely easy to use, simple to produce and functions well.
