Description
Tray for storage, transport and/or display of products, such as fruit and vegetables, and a method therefor
The present invention relates to a tray for storage and transport of products, such as perishable products such as vegetable products and fruit products including apples, pears, kiwi's, tomatoes, melons, stone fruits, and avocados. Such trays are used for crate and box packaging, transportation and safe storage, and preferably enable retail display of fruits, for example.
Fruit trays are known from practice to carry fruits. Such fruit tray is disclosed in AU 2006101010, wherein a tray with cells for individual products is shown, with the cells being configured in a number of rows and columns.
Conventional fruit trays have to provide sufficient strength and enable effective handling of products, specifically fruit. Typically, fruits are very sensitive to product damage, storage and transport conditions. This may influence storage and shelf life of the products possibly resulting in product loss and spillage.
An object of the invention is to obviate or at least reduce some of the above problems and to enable effective storage, transport and/or display of products, specifically perishable products such as fruit and vegetables, and minimizing product damage and product loss or spillage.
This object is achieved with a tray for storage, transport and/or display of products, wherein the tray comprising:
- a number of pocket cells for individual products; and
an outer edge or ridge extending around substantially the entire circumference of the tray.
By providing an outer edge or ridge that extends around substantially the entire circumference and preferably around the entire circumference the strength and stability of the tray is improved. In addition, this enables providing a similar strength and stability for the tray requiring less material, thereby rendering the storage, transport and/or display of products more efficient.
In a preferred embodiment the outer edge or ridge extends with a height in the range of 0.5-5 mm from the tray. This contributes to the strength and stability of the tray. For example, the tray according to the invention has an improved flatness as compared to conventional trays. Also, the tray has tidier edges. This provides an improved visual appearance for a consumer and improves handling of the trays. In addition, in case of stacked trays of products, the tray according to a preferred embodiment of the invention improves apple locking between adjacent layers on corners of the tray. This also improves further handling of the trays.
In a presently preferred embodiment the circumference of the tray is provided with a radius at transitions and corners in the circumference of the tray.
By providing a radius at the corners and/or transitions in the circumference of the tray additional strength and stability are provided to the tray. Distribution of forces that act on the tray are better distributed. Furthermore, in a presently preferred embodiment of the tray, a weight reduction is achieved. This reduces costs of the tray and contributes to an effective and efficient handling of products.
Also, providing the radius in a tray according to the present invention improves the ease to fit the tray in a box. This renders the loading and unloading of the trays in a box more efficient. Furthermore, this contributes to preventing the products to be damaged during handling.
Furthermore, by preventing corners and sharp edges in the circumference of the tray in one of the presently preferred embodiments thereof an improved cooling performance is achieved. This results in perishable products, such as fruit and vegetables to be cooled faster to the desired temperature for storage, transport and/or display. This significantly improves shelf life of the products, and may contribute to a reduction in product loss or spillage.
Experiments have shown an improved air flow between layers of trays with products in a box in a substantial vertical direction, and an improved forced draft through the box in a substantial horizontal direction. Such improved air flow(s) improve product cooling. In fact, heat transfer from the products to the air by convection is significantly improved. This results in a faster cooling process for the products, thereby achieving a longer shelf -life.
In addition, providing corners of the tray with a radius results in a reduction in weight. This improves the cost efficiency of manufacturing the tray. Furthermore, this weight reduction also contributes to reducing transport costs.
In a presently preferred embodiment the products and pocket cells are provided in rows in the tray. Preferably, the rows have a centreline that extends in the longitudinal direction of the row and centrelines of adjacent rows are provided at a distance that is smaller than the average product size, such as the average product diameter. Therefore, products are alternately placed as seen in longitudinal direction of the rows. This increases the number of products that can be placed in the tray. Furthermore, this improves contact between the product and the gas flow, thereby improving conditioning possibilities. This contributes to achieving a longer shelf-life.
The tray according to the invention can be used for different purposes, as was mentioned before. The products that can be placed in or on the tray preferably are perishable products such as fruit and vegetables, including apples, pears, kiwi's, tomatoes, melons, stone fruits, and avocados.
In a presently preferred embodiment the single tray is capable of carrying about 4.8 kg of products, such as apples of different varieties. This may vary by fruit size.
In a presently preferred embodiment the tray is provided with a radius of at least 10 mm, preferably at least 20 mm, and most preferably at least 30 mm. Such radius provides a smooth circumference omitting corners, specifically sharp corners from the tray. This further enhances
weight reduction of the tray and/or cooling performance of a tray and a stack of tray with products, specifically perishable products.
In addition, providing a radius, especially an improved radius, improves the ease to fit the tray into a box or container.
The cooling performance is improved with a tray according to an embodiment of the present invention as more air is provided around the product thereby enabling faster cooling and/or requiring less cooling energy. For example, a reduction of energy required for cooling the products of about 4% was achieved.
Weight reduction reduces the amount of raw material that is required. This provides a cost effective tray. In addition, drying energy is reduced in the manufacturing process of the tray. This also contributes to providing a cost effective tray.
In a further preferred embodiment according to the invention so-called finger holes that are often provided in conventional trays are omitted from the tray. This improves cooling performance.
In a further preferred embodiment according to the invention ribs of conventional tray have been removed and are replaced with an NFnrB on the side of the tray. This contributes to improving the strength of the tray.
In a further preferred embodiment of the tray according to the present invention the configuration of the tray enables improved stacking. Especially the tray interlock allows for better transport efficiency.
In a presently preferred embodiment the tray is manufactured from a fibre material, preferably a moulded fibre material.
The tray according to the invention can be manufactured from numerous materials and mixtures thereof, including moulded fibre, cotton fibre, coconut fibre, wood pulp, and plant fibre including fibres originating from grasses, plastics, foam including foamed moulded fibre. In a presently preferred embodiment the tray is manufactured from a moulded fibre material that at least partly originates from recycled waste such as recycled paper. In another preferred
embodiment the tray comprises fibres originating from biological material, such as bamboo, grass and the like. Combinations of materials are also possible.
In a further preferred embodiment according to the invention the tray comprises holes configured for enabling a gas flow through the tray.
By providing holes a gas flow is enabled through the tray, i.e. in a substantially vertical direction from the bottom side to the top side of the tray. Preferably, the holes comprise a substantially horizontal opening configured for enabling a substantially vertical gas flow through the tray. This provides additional conditioning possibilities for the products in the tray. For example, product cooling can be performed faster. When transporting or storing perishable products this increases shelf life of these products. Preferably, the vertical gas flow through the
holes is used in combination with a substantial horizontal gas flow between stacked trays to improve product conditioning.
It will be understood that a combination of features that are described in this application is possible and are included in a presently preferred embodiment of the tray according to the invention.
The invention further relates to a method for storing, transporting and/or displaying products, such as fruits, comprising the step of providing a tray as described and/or shown in this application, and placing products in the pocket cells.
The same effects and advantages apply for the method for storing, transporting and/or displaying as described for the tray. More specifically, the method according to the invention provides a tray that is easier to load and unload, has a lower weight, and is more stable as compared to conventional trays. In addition, air flow paths for a stack of trays have been improved, resulting in an improved cooling performance, i.e. a faster cool downtime for the products.
