Abstract

A cushioning pad, for use in the cushioning of articles during transportation and storage, comprises an envelope, and a cushioning material within the envelope. To provide an additional protective function to the article whilst being transported and/or stored, an additional component is provided within the pad, to effect such additional protective function. The additional protective function may be (for example) the absorption of undesired gas or liquid produced internally or externally, or the creation of a gas to produce a beneficient effect on the article. Examples of the secondary protective effect include the absorption of ethylene generated by ripening fruit, the absorption of water for the protection of electronic components or engraved tools during transportation, and the generation of sulphur-dioxide gas to reduce the tendency of (e.g.) grapes to rot.

Description

METHOD AND DEVICE FOR PROTECTING ARTICLES DURING TRANSPORTATION AND STORAGE
Description of Invention
This invention is concerned with improvements relating to the transportation and storage of articles, in particular the protection of articles by cushioning means.
In the transportation of fruit and vegetables it is common practice to utilise moulded trays to locate produce during transport, such trays being conveniently of compressed paper pulp ("egg box" material), polystyrene foam or the like. Alternatively or in addition pads may be used to protect the produce against braising. Thus a moulded tray may be placed on the base of a container (conventionally in the form of a wooden box of open construction) and the produce is placed on the tray, a pad being placed over the layer of produce, either for a further layer to be placed thereon, or to cushion the produce against the weight of a further container placed thereon.
However certain produce on ripening produce ethylene gas. and/or the ripening of which is accelerated by the presence of ethylene gas. Such produce includes fruit, such as apples, apricot, avocado, banana, kiwifruit, mango, nectarine, papaya, passion fruit, peach, pear, plum, quince and melon, vegetables such as broccoli, brussei sprouts, cabbage, cauliflower, chicory, cucumbers, lettuce, parsley, spinach, tomatoes, turnip and watercress, and nursery stock (flowers) including carnation, chrysanthemum, gladioli, roses, including potted plants, cuttings, transplants, bulbs, corms, rhizomes and tubers.
Thus, should one ripen, and produce ethylene gas, it will quickly cause other items in the immediate vicinity to ripen also, frequently causing spoilage of an entire container.
Conventionally this problem is reduced by the use of one or more sachets containing an ethylene absorbent material, which are included within each box. Such an ethylene absorbent material is that sold by Stay-Fresh Limited under the trade name "Ethysorb", the material being in the form of small balls of activated alumina impregnated with potassium permanganate. In this way ethylene gas emitted during ripening of fruit, and which is active to cause or accelerate ripening, may be absorbed, reducing early maturation of fresh fruit, and hence reduces spoilage and extends the shelf life.
Problems are however encountered, since the disposition of the sachets within the boxes of produce is determined more or less randomly, and problems are also encountered in disposal of the sachets subsequent to removal of the produce from the containers. In particular difficulty is encountered in providing an incentive to collection of the sachets for return and disposal, and there is thus a problem that children might pick up a sachet from a box of produce.
It is also at times desirable to protect articles against liquid ingress, whether internally or externally produced. For example electronic components or machine tools may need, in addition to protection against shock encountered during transportation, protection against water, oil or other liquids. Additionally, when transporting animals, it is also desirable to provide protection against jarring during travel, but also desirable to absorb urine produced by the animals.
It is further desirable that the various protective functions be effected with minimum of expense and difficulty, and that they may be carried out in as ecologically sound a manner as possible.
It is further desirable that such functions may be carried out by a means which minimises the possibility of the wrong protective means being utilised.
According to this invention there is provided a method of protecting articles during transportation or storage, involving the use of a cushioned pad which comprises an envelope of fluid permeable material, a cushioning material within the envelope, and a fluid absorbent material disposed within the pad.
By the term "fluid absorbent material" as used herein, we mean material having an absorbency significantly greater than that of the cushioning material.
The fluid absorbent material may be disposed separately within the envelope, for example in the form of discrete particles of material disposed generally randomly within the envelope. Alternatively or in addition, the fluid absorbent material may be in the form of a coating on the cushioning material or envelope, whereby the absorbent material may be distributed generally uniformly over the surface of the cushioning material or envelope.
Advantageously the cushioning material comprises paper, preferably shredded, macerated or pulverised paper, conveniently re-cycled paper, and advantageously the paper is in the form of a batt. Advantageously the envelope also comprises paper, preferably comprising primarily wholly paper.
By the use of paper, disposal of the pad may be effected in an ecologically advantageous manner.
The fluid absorbent material may be adapted to absorb a single category of fluid, but if desired more than one fluid absorbent material may be incorporated in the pad.
The fluid absorbent material may be effective to absorb one or more of the following fluids: a) ethylene gas b) water c) oil d) other liquids.
In the transportation or storage of other categories of article, additional problems encountered during transportation cannot be solved by the utilisation of a fluid absorbent material, and in accordance with this invention there is also provided a method of protecting articles during transportation, involving the use of a cushioning pad comprising an envelope of gas-permeable material, a cushioning material within the envelope, and a material disposed within the pad which releases a gas having a beneficial effect on the article during their transportation.
For example in the transportation or storage of grapes, problems are encountered with Botritus Fungal rot, which may quickly cause a large consignment of grapes to be unsaleable. In accordance with this invention, this problem may be alleviated by utilising, within the envelope, a material which releases sulphur-dioxide in a slow but continuous manner, hindering the growth of the rot.
According to this invention there is also provided a cushioned pad for use in carrying out one or other of the methods set out above.
Thus, in accordance with this invention there is provided a cushioned pad comprising an envelope of a fluid-permeable (i.e. gas or liquid permeable) material, a cushioning material within the envelope, and a material within the pad operative to effect one or more of the following functions: a) absorption of ethylene; b) absorption of water; c) absorption of oil; d) absorption of other liquid materials; e) the generation and release of a gas which during transportation effects a protective function.
Conveniently ihe pad has a length which lies within the range 20mm to 20m, having a width which lies within the range 20mm to 2m, being of a thickness appropriate to function, but conveniently lying within the range 3mm to 100mm.
The invention the subject of this application will become clear from the following examples, which have been selected as being illustrative of the invention.
Example 1
Twenty-four cushioning pads as illustrated in the accompanying drawing were produced, each having a size of 50 cm x 25 cm, each comprising an envelope of Kraft paper constructed and arranged to be permeable to ethylene gas and containing, as cushio n i ng material, a batt of shredded/macerated/pulverised paper compressed to a thickness of about 1 cm. Twenty grammes of "Ethysorb" were sprinkled over twelve of the cushioning pads (twenty grammes each) prior to sealing of the batt within an envelope of Kraft. Broccoli and asparagus were packed in equal amounts onto trays and sealed with clingfilm. Half the trays were packed with the produce sitting on the impregnated pads, and half were packed with a produce sitting on unimpregnated pads. The trays were left in simulated supermarket display environments, and readings to ascertain the levels of ethylene gas were taken periodically, over a period of four days. It was found that the ethylene content of the impregnated pads was at the low level of 0.33ppm.
The significant reduction in ethylene content by the use of impregnated pads allows a considerable increase in transportation/shelf life of the produce. Further it allows fruit produce to be picked at a later stage in its ripening process, after which it has absorbed more water, and is in consequence heavier, without any reduction in transportation/shelf life, when compared with the use of sachets containing ethylene absorbent material. Thus, the use of the impregnated pads provides the following advantages:- a) an increase in the value of the produce picked; b) a reduction in spoilage of the produce when packed; c) an increase in the period over which the produce may be displayed for sale, increasing the rate of sale.
Additionally by using impregnated pads, it can be ensured that the produce packed is not detrimentally failed to be provided with protection, such as by the inadvertent omission of sachets, or a sufficient number of sachets.
Whilst the pads have been described in relation to its advantages in the transportation of produce, in relation to consumable produce, the pads may be utilised as shelf liners in (e.g.) a supermarket, to provide protection against bruising, extending the shelf life and improving the appearance of the displayed produce. The pads may be printed in plain colours to further enhance the display area, or simply carry logos or advertising material.
Additionally within the home impregnated pads may be utilised in (e.g.) the salad box of a refrigerator, increasing the time over which produce may be stored in the home prior to being utilised. Additionally where the cushioning material comprises macerated paper, the ethylene absorbent material may be retained within the envelope when presented for re-maceration, pulverisation or other disposal allowing the ethylene absorbent material to be incorporated in the cushioning material for subsequent use, thus obviating the problems of disposal.
Conveniently the ethylene absorbent material is provided in the form of powder or granules to be mixed with the cushioning material, or by spraying or impregnating the cushioning material prior to introduction into the envelope, or by spraying or impregnating the envelope.
Example 2
Cushioning pads similar in size and construction to those of Example 1, but containing as fluid absorbent material a desiccant such as calcium chloride, phosphorous pentoxide, silica gel or molecular sieves, were used to protect electronic components or engraved metal articles during transportation. A significant reduction in deterioration due to the action of moisture was noted.
Example 3
A super-absorbent pad was produced by incorporating into the envelope a liquid absorption material such as cellulose ethers "(e.g. carboxymethyl cellulose and its associated salts) or other cellulose derivatives. Such pads were used in the transportation of whole fresh salmon and bulk fresh meats, and effected the absorption of liquids produced by the articles during transportation. Alternatively or in addition salts of cross-linked polyacrylic acid may be used, including cross-linked sodium polyacrylate. Alternatively or in addition, naturally occurring and modified clay compounds could be used, such as Fullers Earth.
Example 4
Pads similar to those described in Example 3, were utilised on the floor of a cat basket during transportation of the cat and effected the absorption of urine produced during transportation. On conclusion of use, the pad was removed for disposal without encountered the normal problems. If desired, the envelope may comprise a paper material of lower density than Kraft or imitation Kraft, such as compressed tissue material, or Kraft or imitation Kraft material modified to aid fluid permeation.
Example 5
Pads similar to those described in Example 1, but containing sodium metabisulphate in place of the potassium permanganate, were utilised to protect grapes during transportation against infestation by Botritus Fungal rot. The solidum metabisulphate crystals slowly released sulphur-dioxide during transit, and protected the grapes against spread of rot.
In all of the examples given above, the pads were printed clearly with the protection which they were offering, reducing tendency for the wrong category of pad to be used in any particular circumstance. Apart from the active chemical ingredient, the pads may be made of 100% paper and paper fibres, may be 100% re-cyclable or re-usable or biodegradable, available in single pad or roll format, and are capable of being printed whilst in single pad or roll format.
