Abstract
ABSTRACT
The following operations are performed: a single mattress is inserted in a flexible and waterproof wrapper;
compression by squeezing is performed with compressing means to reduce the thickness of the mattress within limits compatible with the elastic structure of the actual mattress, driving out the air from inside the wrapper; the wrapper is made seal-tight by welding;
the squeezed whole thus obtained is rolled up and given a stable shape; the finished item is placed in a container or case suitable for offering the item for sale.

Description
130z86o DESCRIPTION
The inv~ntion relates to a system for p~ckaging sin~le ma~tresse~ in such a ~ay as to ensure ease o`f transport in small overall size also, and above all, for the final purchaser so that he may be relieved from the difficulties o~ carrying the mattre s home. This brings about considerable SAving6~ to which there i8 added the further saving deri~ing ~rom small volume storage.
Methods are known for the packi~g of spring mattresses or other modern type mattresses made with synt~ctic resin foam and other materials, providing for the reduction of thickness of the ~attreRs and fixing the squeezed shape of the mattress for the simultaneous despatch of a plu-rality of mattresses. In the majority of cases a stack of msttresses is compressed to reduce height and secure the mattresse~ - in the squeezed shape they have thus been given - with mechanical means such as straps or re-~istant wrappers; it is thus possible, within restricted space, rOr e~ample in a container, to despatch a plurality Or mattresses to the point Or ~ale, while the final user i8 supplied ~ith a mattress that has again expanded.
There exist a number of syYtems for the reduction Or the volume Or pillows and the like by suction and low vacuu~ in a container containing a single pillow or eushion. A system of this kind cannot be adapted to the single mattress, because of teehnical and economic diffieulties.
According to the invention the problem is solved in economie and technically satisfactory fashion to provide the redueed overall-size paeking of an individually wrapped mattress.
According to one broad aspect of the present in-vention, there is provided a method of individually packaging a mattress comprising the steps of: inserting the mattress into a flexible and sealable wrapper; eompressing the wrapped mattress by squeezing eompression means to reduee the thickness of the mattress within limits eompatible with the elastie strueture of the mattress, and to remove air from the inside of the wrapper;
sealing the wrapper; rolling up the squeezed and sealed mattress;
applying means to retain the rolled, wrapped mattress in the rolled up shape; and placing the rolled mattress in a eontainer therefor.
Aeeording to another broad aspeet of the present invention, there is provided a paekage for an individual mattress eomprising an outer eontainer, a mattress, a wrapper enelosing said mattress and sealingly holding said mattress in a compressed condition with at least a partial vacuum within said wrapper, and retaining means holding said mattress and wrapper in a rolled up configuration, said retained, rolled and wrapped mattress being received in said outer container.
In practice, for reducing the thickness of the mattress, it is possible to proceed with compression ` ~30Z860 with tbe compression means to effect squeezing~ and to the subsequent removal of air by suction with a suction or vacuum pump, to rari~y the air which was not expelled as a result of the compressi~n. In some cases, welding !
i8 effected even without re~oval of air by s~ction~ ¦
expulsion with the press being ~ufficient. '1 The wrapper shall be air_tight~ and it may be of ~f double type~ i.e. there being two wrappers one inside the other~ welded separately or together ffDr sealing.
The welding of the wrapper may be effected after the removal of air by suctio~, or in two stage~, effecting a ;
partial closure and allowing passage for the suction operations~ which pa~sage is subsequently sealed.
The stabilization of the rolled-up shape ~ay be obtained with tapes with closing rings surrounding the rolled-up mattress, or also with adhesive tape which may be disposed around the rolled-up ~attress or, simply, as strips facing the ~utside edge ~hich extends lonfgitu-dinally in the r~lled-up mattress.
The method of packi~g according to the invention may be adopted for ~any types of mattresses, and particularly for those which have an intermediate thickness of rubber or other synthetic elastic foam resin and, possibly, outer layers of artificial or natural fibres along the surfaces ensur-ing the comfort of the user. A mattress of this type can resume its normal expanded, smooth shape after tearing off the wrapper which has kept it in a low vacuum within the space of a few hours.
By way of illustration but not limitation, embodiments of the invention will be hereinafter described with reference to the drawings, in which:
Figs. 1 and 2 show the mattress inserted in its wrapper, in perspective and partial section;
Fig. 3 shows an intermediate stage of compression;
Fig. 4 shows an air removal stage after compression;
Fig. 5 shows a partial cross-section of the squeezed product subjected to vacuum;
Fig. 6 shows a stage of rolling up of the flattened item;
Fig. 7 shows the flattened item rolled up, Fig. 8 shows the rolled-up item packed in its individual packing.
As illustrated on the attached drawing, 1 denotes `` 1302860 the s ttress in its normal presentation and 3 a wrapper intended to house it, said wrapper being mostly a film o~ synthetic air-proof, ~eldable material~ with a consis-tency adequate to withdtand the stresses it will be ex-pected to undergo. This wrapper may al60 constitute a sh0ath forstoring the re-expanded mattress in the h~me.
The wrapper may also be a do~ble one. The mattress 1 with its sheath 3 is placed in a press 5A, 5B which is able to compress it from the normal size denoted by 1 through a si~e lN to the squeezed size denoted by lS, squeezing being effected by mechanical action between the two parts 5A~ 5B of the pre~s; with the pressing operation - the ~rapper 3 being still at lea~t partly open - the greater part of the air contained in the wrapper 3 is squeezed out.
Immediately after pressing, and before the action of the press has been stopped and, anyhow, before a re-expan~ion of the mattress~ with a suction pump or a ~acuum pump, the remaining air may be rarefied from the wrapper 3 to a degree of ~acuum kept within the reasonable limits for the purposes mentioned.
At the end o~ the squeezing and the desired suction the wrapper 3 is sealed, and then the mattress u~it " 1302~60 remains squeezed inside the wrapper without any po-~sibi_ lity of re-expansion.
The mattress thus squeezed and secured inside the wrapper is relatiYely tightly rolled up as ~hown at 7, until the shape sh~wn at 9 is reached, a ~hape which is stabilized with the application of means ~or holding the outside edge 9A of the mattress and its wrapper; theoe retaining means may be represented by two or more pieces 10 of relatively strong adh~si~e tape, applied transver-sally and facing the edge 9A.
In the pre~entation sho~n at 9 the squeezed mattress assumes ~ very limited and compact overall size and may th~refore be inserted in a container 12 which may be cylindrical or parallelepipedic. Thi~ container is not intended to withstand a thrust from the outside towards the inside of the ~queezed and rolled-up mattress which is stabilized by retaining means such as means 10. The container ~ay be of cardboard or synthetic resin, as a box, a cube or other shape, to be opened at the end or longitudinally, all these containers being equivalent one with the otber. A container of this type msy be advan-tageously fittod with a grip 14 for eace of transport in a horizontal position.
_ 8 -Arter having been rolled up, the mattres6 held by the retaining ~eans ~ay be in such a condition as to no longer require the low vacuum conditions.
The ~attress re~oved from the container may be re-leased from the means 10 and stretched out, and the wrapper 3 may be opened in ~uch a manner as to allow the entry of air and thus permit the re-expansion of the mattress which, more or less speedily, re6umes the thick-ness intended for use.
Mattresses packed as indicated above may be stored for shipment ~nd warehousing in relatively very economic man~er, and are ~aleable individually al50 in the packed presentation, as a result of which the final uscr ~an conveniently carry the mattress purchased with the mean~
at his own disposal, without:diffiCulty or extra expense.
The drawing ~ho~8 only one example of the invention which ~ay vary as to shapes and arrangements.
