Definitions
- the present invention relates to a filling and filling material packaging as well as the process and the machine for its manufacture.
- the present invention relates to a material for protecting objects enclosed in a package, the said material having a wedging action and / or filling of free spaces and / or shock absorption and resistance to pressure.
- the main material used consists of polymeric foams or expanded synthetic materials. These materials are useful in that they fill the irregular cavities formed between the packaged object and the packaging container. But the main disadvantages of these materials are that they have to be produced by specialized companies, and to demand large volumes of transport and storage.
- US Patent 3,244,347 describes a packaging wedging and filling system, but limited to the corners of the packaging. The system is not suitable for filling irregular cavities between the wrapped object and the packaging container.
- shock absorption systems forming mattresses or packing materials, but these systems are not suitable for filling of irregular cavities between the wrapped object and the packaging container.
- US Patent 5,173,352 has proposed accordion pleated strips, but the properties of these materials in terms of cushioning and resistance to the crushing is poor due to the fact that the strips more or less overlap into each other.
- German patent application 4018173 proposed protective materials cushioning (or padding) and filling consisting of hollow bodies in the form of cylinders or prisms derived from precut strips, the two ends of which are glued together or stuck together. But these materials have resistance to poor crushing and flatten too easily.
- the use of sheet elements of paper is recognized as making it possible to avoid expanded polystyrene.
- Patent US 5595811 of priority January 31, 1992 base for the preamble of claim 1 proposed such elements of bowl-shaped paper with more or less accentuated pleating of the paper, the various folds starting all from the bottom of the bowl.
- US-A-2,685,827 also describes elements of paper in the form of bowl with pleating; furthermore a crushing of these elements is described ( Figure 5), but the crushing disappears the shape of bowl or bucket of the elements of paper.
- European patent application 667304 describes a padding material consisting of hollow bodies derived from strips similar to those of the application German 4018173; but these hollow bodies can also either be provided with folds longitudinal, or have a steep bottom giving them a general pot shape. In in this case the folds extend parallel to each other from (or towards) the bottom of the pot.
- Lining or padding or filling materials having these forms of bowl according to these last three documents usually have resistance poor crushing, especially due to transverse steering forces to the side walls, and they flatten out easily.
- An object of the present invention is to provide a cushioning material and packing filling, avoiding as much as possible the disadvantages of the materials known.
- Another object of the present invention is to provide a cushioning material and economical filling, inexpensive, and easy to produce by non- specialized.

- Another object of the present invention is to provide cushioning materials likely to be prepared from rolls of paper, and more particularly from rolls of high resistance paper, and more particularly rolls of plain paper.
- Another object of the present invention is to provide cushioning materials and a process for their manufacture such that this process can be implemented by the user or near the place of use of the cushioning material.
- Another object of the present invention is to provide a cushioning material and / or filling suitable for advertising.
- the word bucket or bowl is used to indicate that there is a bottom like in a container although the folded walls do not resemble not those of a usual plain-walled bucket.
- the bottom of the bucket is not pleated, but its walls are not plain, and more precisely pleated in an irregular zigzag configuration; this this irregular zigzag configuration is as obtainable (or as obtained) by crushing a sheet of paper along its length, in other words transversely to the thickness of this sheet, towards the bottom of the bucket.
- the folds of the wall of the bucket are a plurality of plies, generally more than 10, preferably more than 25 plies.
- the majority of folds do not not extend from (or to) the bottom (b2) of the bucket, and, advantageously, they intersect each other, or form angles or intersections between them.
- a large part of the folds (more than 20% of them), generally more than 40% of them (but less than 95%), have a approximate general orientation parallel to the plane representing the bottom (b2) of the bucket.
- This orientation parallel to the bottom of the bucket expresses, as will be seen more far about the method of making the buckets, that the thick walls came from crushing of the sheets of paper in a direction substantially perpendicular to the bottom of the bucket.
- These approximately parallel folds can form angles up to 45 °, on one side or the other, with the bottom of the bucket.
- the buckets according to the invention advantageously have a smooth surface, of preferably the bottom, flat or rounded allowing to inscribe readable advertising conveniently.
- Their overall (average) outside diameter is between 1 and 15 cm, preferably between 2.6 and 10 cm.
- the walls of the buckets, from a overwrite, are not united and hardly allow a readable advertisement conveniently.
- the ratio (or ratio) of the volume of the wedging piece on the surface of the paper used is in a range from 0.01 to 5 cm 3 / cm 2 , preferably from 0.05 to 1 cm 3 / cm 2 , and more preferably from 0.1 to 1 cm 3 / cm 2
- the ratio (or ratio) of the volume of the cushioning material according to the invention by compared to the initial volume of paper necessary for its production is generally between 10 and 300, preferably between 40 and 200, and more preferably still between 50 and 100.
- the shaped wedging pieces general hollow cylinder with thick side walls have a ratio (or ratio) of average outside diameter of the cylinder over the height of the cylinder advantageously between 0.2 and 8, preferably between 0.9 and 6, more preferably between 0.9 and 3.
- the ratio (or ratio) of the outside diameter of the cylinder to the average thickness of the side wall is advantageously between 2.1 and 8, preferably between 2.2 and 6.
- the wedging and / or padding and / or packing filling element is also called “chocking piece” in the present text.
- the invention also relates to a cushioning and / or filling material.
- packaging characterized in that it contains a plurality of wedging elements according to the invention, generally more than 10, advantageously more than 20.
- This plurality can include up to ten or several dozen supporting parts, or even hundreds, but this is not an essential feature of the invention.
- An advantage of the invention is that the wedging pieces are very resistant mechanically, in particular resistant to crushing or to deforming forces various, the deformations being all the more to be avoided as they could cause loss the stalling nature of said pieces.
- the cushioning material has a cushioning effect excellent, and a very good occupancy rate of empty volumes in packaging.
- Another advantage of the wedging and filling elements according to the invention is that they don't tend to or have the ability to nest into each other.
- rigid or even very rigid paper is recommended in the invention because it favors obtaining wedging parts which are more resistant to crushing.
- the paper known as Kraft paper is particularly advantageous to obtain this result.
- the paper used in the invention can be multilayer, but it is preferred generally, especially for reasons of efficiency and economy, use single layer paper.
- the invention also relates to a method for manufacturing setting material as well as a machine intended to implement this process.
- the crushing being operated while the stamping means remains, after stamping, in the hollow channel of the matrix, and defines in this position, with the inner wall of the hollow channel, a tubular space able to accommodate the side walls of the preliminary basins and to receive the crushing means.
- Feeding the first stage using paper in the form of (large) flat sheet is advantageously produced by unwinding a roll of paper.
- the hollow channels are preferably cylindrical in shape, which can be in particular in the form of a cylinder with a round or polygonal base, regular or irregular; this shape can be serrated or grooved or grooved.
- the small sheets of paper have, as indicated above, a surface restraint.
- restricted surface is meant that the surface of the small leaves is more small than that of the initial large leaf, insofar as the large leaf has undergone a cutting, and even two cutting, one longitudinal, the other transverse.
- these small sheets of restricted surface often have a form of rectangle or square or circle, the dimension of the sides (or the diameter for a often being between 3 and 40 cm, preferably between 4 and 25 cm, more preferably between 5 and 20 cm.
- the invention also relates to a machine intended for setting up implements the method according to the invention.
- the elements of this machine are numbered in the following description using the numbers in FIGS. 1 to 5, it being understood as the following description of the said machine (and the corresponding claims) must be understood without the mention of these numbers, they are not part of the description of the machine itself and having only one role to facilitate the understanding of the text.
- the pushing or drawing means are also provided with means actuating this pushing or stamping.
- the hollow channels are preferably cylindrical.
- These hollow cylinders (15), as well as the other cylinders mentioned in the description of the invention, can be cylinders with a round base or polygonal, regular or irregular.
- the pushing or crushing means (6) can be in the form of cylinders, or discs (i.e. a thin cylinder) linked to one or more rods (or bars), these being used to connect the means actuating the movement and the discs exerting the pushing or crushing of the sheets of paper.
- These means of pushing can also have a piston shape.
- the pushing or crushing means (6) are capable of sliding in the hollow channels (or cylinder) (15).
- the pushing or stamping means (5) are advantageously cylinders, which can slide inside the pushing means (6). For some reasons of quality and safety, it is advantageous that these cylinders have a tip rounded, even spherical or ovoid.
- the means to avoid jamming of paper are advantageously grooves or serrations or grooves arranged on the interior walls or exterior of the cylinders, in particular hollow channels (or cylinders) (15), pushing means (6), and pushing means (5), in particular when these pushing means (5) and (6) are cylindrical.
- the size and shape of the grooves or grooves can vary widely without departing from the scope of the invention. Generally the size of these grooves or serrations or grooves are included between 1/2 mm and 1 cm, but sizes exceeding these limits can also be used without departing from the scope of the invention.
- Grooves or serrations or grooves are advantageously arranged on more than half of the surface of the cylinders (hollow channels and pushing means), preferably on more than 2/3 of these surfaces, and even more preferably on all of these surfaces.
