Description

Improved Article of Luggage
The present invention relates to an improved article of luggage for use by travellers, and a method of manufacture of such a case.
Generally suitcases, or other articles of luggage, can be divided into 'hard' and 'soft' constructions. Broadly, hard cases are those in which the top, bottom and sides cannot be pierced by a blade or needle (or at least substantially resist this) and those that are not of 'hard' construction are considered to be of 'soft' construction.
Hard cases are generally formed from a moulded plastics material. Such a material needs to be sufficiently robust to withstand the various environments to which the article of luggage will be subjected.
For example articles of luggage used in air travel will be manhandled at various stages, by a user when transporting the article of luggage to an airport, by staff in conveying the article of luggage onto and off an aircraft and then to a baggage reclaim area, and again by a user when retrieving the article of luggage and transporting of the article of luggage to the intended destination. During this process, the article of luggage in addition to being subject to various impacts and abrasions will also be subject to direct sunlight, fluids such as rainwater, and other environmental conditions. The article of luggage needs to be resistant to such exposures and not stain or otherwise become discoloured as a result. It will be appreciated that an article of luggage may also encounter temperature changes, for example when transported from a milder climate to a warmer one, or vice versa. Such temperature changes may affect the durability of the moulded plastics material, and may also affect the contents of the article of luggage.
An article of luggage will need to maintain its intended robustness during the intended life of the article, even if, for example subject to direct sunlight when being stored. An article of luggage that is subject to fading when exposed for prolonged periods to direct sunlight will not meet with a favourable response from a user.
In addition, since airlines impose weight limits on the luggage of a passenger, consumers seek out articles of luggage that are perceived not to contribute unnecessarily to this weight allowance. As such manufacturers look to manufacture articles of luggage that are as light as possible in relation to the intended internal storage volume of the article of luggage.
Currently the shells of most hard cases are injection moulded using polypropylene or vacuum formed using polypropylene, acrylonitrile butadiene styrene (ABS) or ABS/polycarbonate composites. In either method, the shells may be moulded from a single sheet of plastics material or multiple solid layers. There is a need for a lighter hard shell case than is currently possible with known techniques and materials, while still retaining desirable characteristics of robustness, colour durability and the like.
According to a first aspect of the present invention, a method of moulding a shell for an article of luggage comprises the steps of
providing a plastics sheet comprising an upper layer and a lower layer, the upper layer and the lower layer being connected to one another by a plurality of intermediate strips;
heating the plastics sheet;
introducing a mould to the heated plastics sheet;
vacuum moulding the heated plastics sheet to the mould to form a plastics shell;
withdrawing mould from the formed plastics shell; and
trimming the formed plastics shell form the heated plastics sheet.
Preferably the plastics sheet is polycarbonate.
Preferably the plastics sheet is formed by extrusion.
Preferably the intermediate strips are provided substantially normal to the upper layer and the lower layer of the plastics sheet.
Preferably the step of heating the plastics sheet comprises the steps of i) performing a first heating step,
ii) allowing the plastics sheet to cool during an interval; and iii) performing a second heating step.
Preferably the first heating step is performed for between 30 and 50 seconds, more preferably around 40 seconds.
Preferably, the interval is between 15 and 25 seconds, more preferably around 20 seconds.
Preferably, the second heating step is performed for between 25 and 35 seconds, more preferably around 30 seconds.
According to a second aspect of the present invention an article of luggage comprises a first shell and a second shell, one or both of the shells being produced according to the first aspect of the invention, a zip arrangement hingedly connecting the first shell and the second shell, a plurality of wheel assemblies connected to one or both of the first shell and the second shell and a towing handle assembly secured to one of the first shell and the second shell.
The invention has as an advantage that the shells formed according to the first aspect of the invention use less plastic than a conventional moulded sheet or sheets. The shells formed in this way also have more flexibility and more impact resistance than known injection moulded or vacuumed formed shells. It is a further advantage that air pockets formed in the shell produced by the method of the present invention can serve to insulate the contents of the article of luggage against temperature changes.
The invention will now be described, by way of example only, in relation to the accompanying Figures, in which
Figure 1 shows a schematic perspective view of a section of a plastics sheet for use in accordance with the present invention;
Figure 2 shows a schematic view of a first step in the manufacturing process of the present invention;
Figure 3 shows a schematic view of a second step in the manufacturing process of the present invention;
Figure 4 shows a schematic view of a third step in the manufacturing process of the present invention;
Figure 5 shows a schematic view of the plastics sheet following a fourth step in the manufacturing process of the present invention; and
Figure 6 shows a schematic view of an article of luggage formed in accordance with the present invention.
Referring first to Figure 1, there can be seen a part of a plastics sheet 2 for use in the present invention . The plastics sheet 2 comprises an upper layer 4 and a lower layer 6, the upper layer 4 and the lower layer 6 being connected to one another by a plurality of intermediate strips 10. The intermediate strips 10 can be seen to be arranged substantially vertically with respect to the substantially horizontal upper and lower layers 4,6. The lower layer 6 can be seen to provide a lower surface of the plastics sheet 2. The sheet is formed of any suitable material, preferably polypropylene. More preferably, the sheet is formed from extruded polypropylene.
In the first stage of the manufacturing process of the present invention the plastics sheet 2 is heated. As seen in Figure 2 this is achieved by heating the plastics sheet both from above and below, for example by using upper and lower heating plates 14,16. Care is required in the heating of the plastics sheet 2 since the material is comparatively thin and if the sheet is heated continuously and for too long the heat will not be spread evenly potentially causing a failure of the plastics sheet during the subsequent manufacturing steps.
Accordingly, it has been found advantageous to heat the plastics sheet 2 in a number of stages. Preferably a first heating step is performed, heating is stopped for an interval and a second heating step is then performed. More preferably the first heating step is performed for between 30 and 50 seconds, more preferably around 40 seconds. More preferably, the interval is between 15 and 25 seconds, more preferably around 20 seconds. More preferably, the second heating step is performed for between 25 and 35 seconds, more preferably around 30 seconds.
The heating steps ensure that the plastics sheet 2 is sufficiently malleable throughout to enable the following steps to be performed. In particular, following the second heating step a mould 26 is introduced into the lower surface of the plastics sheet 2, causing the plastics sheet 2 to be deformed (Figure 3). The plastics sheet 2 is secured, preferably clamped, around its edges to prevent the mould from simply raising the plastics sheet 2. It may be noted that there is no blow moulding in the formation of the shell . This is to prevent the inside of the shell formed by the inventive method from losing its shape during the manufacturing process.
Once the mould 26 is in position, the plastics sheet 2 is vacuum moulded to the mould (Figure 4) by activating a suitably arranged vacuum pump (not shown). Once the plastics sheet 2 has cooled sufficiently to retain the moulded shape, the vacuum pump is turned off and the mould removed from the plastics sheet (Figure 5). Again, it will be understood that since the plastics sheet 2 is secured about is edges, this will keep the plastics sheet 2 in position while the mould 26 is lowered and withdrawn from the moulded plastics sheet 2.
The moulded plastics sheet 2 can then be trimmed to produce a shell suitable for use in the assembly of an article of luggage (Figure 6).
In particular, the heating steps have been found to improve the moulding process by addressing the problem of the plastics sheet 2 perhaps becoming wrinkled, or in some instances fraying, at the corners of the shell 52 formed by the moulding process. It will be understood that the appearance of wrinkles at the corners is undesirable as it detracts from the aesthetic appearance of the moulded shell and that fraying is particularly undesirable as it means the shell is unsuitable for use in an article of luggage.
The construction of the plastics sheet used in the present invention allows for the production of a shell incorporating less plastics material than a shell of a like volume produced by the injection moulding and vacuum forming methods acknowledged above, thereby contributing to the overall lightness of an article of luggage formed using shells produced in accordance with the present invention.
It has additionally been found that the shells produced in accordance with the present invention are more flexible and have greater impact resistance than plastics shells produced using the injection moulding and vacuum forming methods acknowledged above.
Figure 6 shows by way of example an article of luggage 50 made of two such shells 52,54. The shells being hingedly connected by way of a zip arrangement 56 and provided with a plurality of wheel assemblies 58 and a towing handle assembly 60.
