- the manufacturing processes for this type of container usually include the stages of:
- Another disadvantage is the power needed for the punching head of the pressing station, since a number of layers have to be pressed together. Furthermore, the tolerance between the punching heads and the dies of the pressing station has to be quite large, since a plurality of layers of a certain thickness has to be pressed all together.

Abstract
Description
- The present invention relates to a process for the manufacturing of containers, to a machine for manufacturing the same and to a container obtained with this process, said containers being formed from a plurality of strips superposed and joined together and being especially suitable for containing foods.
- Known in the art are various containers for foods which are used for the sale or transportation thereof, these containers usually being for use once only.
- These containers are formed by a plurality of layers of sheet material, the number and the material of the layers depending upon the type of foods to be contained. The layers are normally of cardboard or expanded polystyrene, also including a layer of laminated material suitable for being in contact with foods.
- In some cases, and depending on the type of product to be contained, the containers can include an additional layer of absorbent material placed beneath the layer of material suitable for being in contact with foods.
- One major disadvantage of some of these containers lies in the use of expanded polystyrene, which is not a very ecological product since it is not very economically feasible to recycle it.
- Cardboard containers have the disadvantage of not being very strong and not retaining their shape, that is, they deform and do not recover their original shape. This is due to the fact that during the pressing stage to shape the container according to a predetermined design folds are formed at the pressed zones, and these folds can deform if pressure is applied on same.
- The manufacturing processes for this type of container usually include the stages of:
- gluing and joining of a plurality of strips;
- die-cutting of said plurality of strips already joined together; and
- pressing of said strips in order to shape the container according to a predetermined design.
- In the known processes the strips are first glued, joining them together, are die-cut and all the strips are then pressed together. This pressing of all the strips together is what leads to the formation of folds.
- Moreover, the known processes have the disadvantage that they are carried out by heat processes at very high temperatures and that the thickness of the strips is limited, which also leads to the containers not being very strong.
- Another disadvantage is the power needed for the punching head of the pressing station, since a number of layers have to be pressed together. Furthermore, the tolerance between the punching heads and the dies of the pressing station has to be quite large, since a plurality of layers of a certain thickness has to be pressed all together.
- US-A-2 116 362 discloses an apparatus for making cartons comprising an endless carrier having a step by step movement; a series of formers mounted on said carrier; means for feeding to each former a sheet of relatively thin flexible material; a series of means for folding the sheet about the respective former to provide a bag having its outer end closed and inner end open; means for advancing in step by step manner a continuous strip of carton body blanks; means for periodically severing a body blank from such strip, each carton body including a bottom panel and a side panel on opposite sides of the bottom panel and tabs projecting from the ends of such panels; a series of means for folding a carton body blank over the folded bag disposed on one side of said formers; means for feeding in limited relation to the movement of said carrier a continuous strip of end panels to the carrier in the path of movement of the formers; means for severing an end panel from each strip; and means for securing a severed end panel to the tabs on opposite ends of the folded carton body blank.
- US-A-2 776 608 discloses a method of making containers having a plurality of layers of material which comprises assembling a plurality of sheets of material, initially applying heat to a limited area and thereby adhering the sheets to each other to form a composite blank, simultaneously folding all the sheets of the blank into a tubular body portion in which the layers are superimposed, folding the elements at one end of the blank to close one end of the body portion, adhesively securing at least a portion of said end elements to retain the elements and container body portion in folded position, and subsequently securing said side seam, and welding the sheets of material to each other by applying heat throughout the entire area of said body portion to form a smooth, strong, multiple-layered container.
- The process of the invention resolves the aforesaid disadvantages, while providing other advantages which will be described below.
- According to a first aspect, the present invention relates to a process for the manufacture of containers, characterized in that it comprises the stages of:
- gluing of said plurality of strips from rolls of sheet material;
- die-cutting of said plurality of strips; and
- pressing and joining together of said strips in order to make up the container according to a design predetermined individually for each strip, by adding the other strips as they are pressed successively and individually to a first already-pressed strip.
- With the process of the invention containers are formed with the number of strips desired, thus achieving a suitable thickness, without limitation. A container of considerable strength is thus achieved, forming folds of very small dimensions, with high shape-retention, that is, if the container deforms it returns to its original shape.
- The pressing stage can be carried out using cold or hot process, achieving very high manufacturing speeds compared with the known processes.
- Moreover, little power is needed to press the strips, since only one strip is pressed at each of the stations, not all the strips together as has been done to date.
- Advantageously, the process of the invention also includes an additional stage of cutting away the edges of the container after pressing and joining together all the strips.
- Preferably, the container is made by taking up strips from at least three rolls of sheet materials, the first sheet material being suitable for being in contact with foods and, when all the strips have been pressed and joined together, the one left on the internal part of the container.
- Also preferably, at least one of said rolls is cardboard, the strip(s) which are die-cut from the roll(s) of cardboard being fitted between the first strip of material suitable for being in contact with foods and the strip applied on the outermost part when all the strips have been pressed and joined together.
- Where necessary, and depending on the product the container is to contain, at the die-cutting stage some slots or orifices can be made in the first strip of material suitable for being in contact with foods. Where such slots or orifices are made, a zone of the cardboard strip(s) corresponding to the slots or orifices of the first strip is treated for absorption at predetermined zones of the juices produced by the product to be packaged.
- Advantageously, during the stage of pressing and joining together of the strips, that latter are secured by means of vacuum absorption.
- Preferably, treatment of the cardboard strip(s) is carried out by spraying a material suitable for preventing porosity at certain zones of said strip(s).
- In the die-cutting stage of the invention the strips are cut out in advance and marks made for carrying out the subsequent pressing on each of the strips.
- Advantageously, at least one of said strips is of dimensions different from the other strips. A reinforcement or absorbent strip of smaller dimensions can thus be included between the other strips.
- According to a second aspect, the present invention also relates to a machine for manufacturing containers, as is claimed in claim 11.
- In this way, the tolerance between the die and the punching head increases as the thickness increases, thereby achieving very precise pressing.
- Advantageously, the machine of the invention also includes a cutting station at which the edges of the already-shaped container are cut after all the strips have been joined together.
- Where necessary, the machine can also include at least one additional station for treating a zone of at least one of said strips.
- Advantageously, the rolls of sheet material are positioned one beside the other, with the roll corresponding to the innermost strip of the already-formed container placed at one end and the roll corresponding to the outermost strip of the already-formed container at the other end.
- Also advantageously, the dies of the pressing stations are positioned one beside the other facing the outlet of sheet material from the rolls.
- According to a third aspect, the present invention also relates to a container manufactured according to the foregoing process and with the machine described.
- For a better understanding of all that has been set out herein, some drawings are attached which show, schematically and solely by way of non-restrictive example, a practical case of embodiment.
- Figure 1 is a schematic plan view of the machine of the invention; and
- Figure 2 is a schematic elevation view of the machine of the invention.
-
- As can be seen in Figure 1, which shows an embodiment of the machine of the invention, the machine comprises:
- four
gluing stations 2; - four die-
cutting stations 3 which die-cut a plurality of strips which come from four rolls ofsheet material - four
pressing stations 4, made up of a plurality ofpunch heads 5 and dies, the joining together of all the strips being carried out on these pressing stations; - means of
transfer 6, such as for example a conveyor belt, to take the already-pressed strip or strips from onepressing station 4 to the others, so that a first strip passes successively through all thepressing stations 4, individually adding one strip at each of said stations to said first strip until the final make-up of the container has been achieved; - two
stations 8 for treating some zones of two of said strips, at which a substance is sprayed onto said zones to prevent them being porous; and - a
cutting station 7 at which the edges of the already-formed container are cut away following the joining together of all the strips. - It should be noted that this machine is designed for the manufacturing of containers of four layers of sheet material, though containers of more or fewer layers can be manufactured by adding or removing the corresponding stations.
- Preferably, the innermost strip of the formed container is of a material suitable for being in contact with foods and can be printed on if wished. This strip can be made of a heat-fusible and impermeable material, depending on requirements.
- The outermost sheet of the formed container can be made of any suitable material, such as paper or others, and can be printed on.
- The intermediate strip or strips, two in the case of the container manufactured with the machine shown in the drawings, are preferably of cardboard.
- In order to manufacture the containers, the rolls of
sheet material - The machine of the invention will be synchronised in such a way that, when it comes into operation, the material is fed first from the first roll 1a, the roll on the left of the machine shown.
- The sheet material will pass first through the gluing
station 2, where one section of the material will be glued. Preferably, the glue used will be heat-fusible, being allowed to cool before pressing. - The sheet material is then die-cut and marked according to a predetermined design, with marks made for subsequent pressing thereof.
- The strip is then pressed, by either cold or hot process. If carried out by hot process, the temperature reached will not be very high, but only sufficient to heat the glue on the strip. The part of the pressing station which will be heated will always be the die, while the punching
head 5 will remain cold. - This already-pressed strip will pass on to the next
pressing station 4 by means of theconveyer belt 6, on which a second strip will be incorporated onto said first strip when it is pressed. Said second strip had passed through the same processes as the first strip. - This process for incorporating a strip will be carried out successively until the entire container has been formed.
- The machine of the invention will be synchronised in such a way that container manufacturing is carried out continuously.
- An additional operation of spraying onto a zone of the sheet material can be carried out on the intermediate sheet materials. This spraying is carried out in order to treat some zones, thereby preventing porosity at some zones of the strip or strips.
- It is important to stress that gluing of the first strip is not essential, and the gluing station corresponding to the first roll 1a can be removed.
- It should be noted that one of the strips making up the container can be of dimensions different from those of the other layers. For example, a reinforcement strip of smaller dimensions can be included between the other strips.
- Moreover, at least one of the rolls can be positioned to feed material in a different direction from the rest of the rolls, thereby allowing the fibres of the sheet material from this roll to cross over the fibres of the other sheet materials. The container is thus provided with greater shape stability, preventing deformations.
- Although reference has been made to one specific embodiment of the invention, it is obvious to an expert in the subject that both the process and the machine described can have many variations and modifications and that all the details mentioned can be replaced by others which are technically equivalent without departing from the scope of protection defined by the attached claims.
- Some of these modifications might consist, for example, in the arrangement of the gluing and die-cutting stations, with the gluing being carried out before the die-cutting, or vice versa.
- Another modification might relate to the means of transfer of the already-formed strips. In the embodiment shown, these means of transfer consist of a conveyor belt provided with the dies, the latter being attached onto the belt. The same die thus passes successively through all the pressing stations. It should be noted that the punching heads could be attached onto the conveyor belt, so that the punching heads would pass through all the pressing stations.
