The disclosure relates to the field of luggage, such as suitcases, comprising at least one moulded shell.
One advantage of luggage that comprises at least one moulded shell is that the moulded shell provides more protection to contents of the luggage than a fabric alternative. Furthermore, by contrast with fabric, a moulded shell retains its shape without the need for other structure-defining elements.
In fabric luggage, fabric panels may be fastened together in order to achieve a three-dimensional form. Such fastening is generally straightforward, for example by stitching. By contrast, it is more complex to fasten single piece moulded portions to other elements and, in any case, it is not necessary to do so in order to obtain a three-dimensional form since the moulded portion itself provides the three-dimensional form.
GB 2580666, in common ownership with the present disclosure, discloses a moulded luggage shell with an exterior fabric panel. However, the protective advantages of the moulded shell do not provide protection to the contents of the pocket since the exterior surface of the pocket is fabric.
Against this background there is provided an article of luggage comprising:
In this way, advantages of a moulded portion for protection of suitcase contents can be exploited in the context of pockets accessible from an exterior of the article of luggage without having to open the lid of the article of luggage. Furthermore, the interior surface of the second stepped portion provides a moulded surface at a lower edge of the upper pocket which enables use of the moulded lid shell for protection of contents at the lower edge of the upper pocket.
Optionally, the upper and lower stepped portions are substantially perpendicular to the lid opening plane. Optionally, the lower stepped portion may comprise the first aperture. In this way, the first aperture may be less obvious, less accessible for swift access by a third party, and more protected from damage.
The moulded concave shell may further comprise a first recessed portion between the upper and lower stepped portions and set back from the upper and lower protruded portions.
The concave moulded shell may further comprise a second recessed portion that is set back from the upper protruded portion and substantially perpendicular to the lid opening plane, and a top stepped portion on an opposite side of the upper protruded portion from the upper stepped portion, wherein the second aperture is located in the top stepped portion. In this way, the second aperture may be less obvious, less accessible for swift access by a third party, and more protected from damage.
The lower pocket may comprises a first fabric receptacle having a first receptacle opening, the first receptacle opening having a first side and a second side, wherein the first side of the first receptacle opening is fastened to the moulded shell on a first side of the first aperture and the second side of the first receptacle opening is fastened to the moulded shell on a second side of the first aperture. In this way, the fabric receptacle may prevent significant movement of contents of the pocket within the moulded shell.
The first receptacle opening may be closable by a first pocket zipper having a first zipper tape on the first side of the first receptacle opening and a second zipper tape on the second side of the first receptacle opening, such that both the first aperture and the fabric receptacle are openable and closable by the first pocket zipper.
The first zipper tape may be fastened to the moulded shell by stitching and the second zipper tape is fastened to the moulded shell by stitching. In this way, one zipper provides the functionality to close the aperture and the pocket.

The second receptacle opening may be closable by an upper pocket zipper having a primary zipper tape on the first side of the second receptacle opening and a secondary zipper tape on the second side of the second receptacle opening, such that both the second aperture and the second fabric receptacle are openable and closable by the second pocket zipper. In this way, one zipper provides the functionality to close the aperture and the pocket.
The article of luggage may further comprise a lid liner fastened to the second moulded portion within and proximate the lid opening such that the first fabric receptacle and, where present, the second receptacle are located between the lid liner and the moulded portion. In this way, further restriction of movement of pocket contents may be provided.
The article of luggage may further comprise a body liner fastened to the body within and proximate the body opening.
Optionally, in the closed position in which the body and the lid openings cooperate such that the body and lid containment portions are enclosed, cooperation is provided by a primary zipper comprising a first tape fastened to the first moulded portion proximate the base opening and a second tape fastened to the second moulded portion proximate the lid opening.
The article of luggage may further comprise a plurality of protruding wheel systems, each comprising at least one wheel, wherein each protruding wheel system is fastened to an exterior of the first moulded portion.
Each wheel system may comprise a connection element and a wheel unit, wherein the wheel unit is rotatable relative to the connection element about a generally vertical axis that sits outside a footprint of the base.
Optionally, the article of luggage may be is in the form of a suitcase.

The lower pocket 162 comprises a first fabric receptacle having a first receptacle opening, the first receptacle opening having a first side and a second side. The first side is fastened to the moulded shell on a first side of the first aperture towards a front of the first recessed portion 165 and the second side of the first receptacle opening is fastened to the moulded shell on a second side of the first aperture towards a rear of the first recessed portion 165.
The first receptacle opening is closable by a first pocket zipper having a first zipper tape on the first side of the first receptacle opening and a second zipper tape on the second side of the first receptacle opening, such that both the first aperture 161 and the first fabric receptacle are openable and closable by the first pocket zipper.
The first zipper tape may be fastened to the moulded shell by stitching and the second zipper tape may be fastened to the moulded shell by stitching.
In this way the stitching of the first zipper tape and the second zipper tape to the moulded shell not only provides the functionality of opening and closing the lower pocket 162 via the first pocket zipper but also provides the functionality of retaining the first fabric receptacle in position.
It may be that the first fabric receptacle is not otherwise fastened to the first moulded shell. This reduces manufacturing steps and costs.
The lid containment volume may be provided with a fabric lining such that the first fabric receptacle may be located between the moulded lid and the fabric lining so as to provide some restriction of movement of the first fabric receptacle beyond the stitching around the zipper tapes.
By providing the first aperture 161 in the lower stepped portion 160, it more discrete than would be the case if it were in the front face and also the stitching and zipper is less vulnerable to damage from handling such as in airport luggage handling areas. Furthermore, the lower pocket 162 lends itself well to receiving and accommodating the kinds of items, like laptop computers and tablets, that travelers like to be accessible in an exterior pocket rather than in the main body of the luggage.
The body containment volume may also be provided with a fabric lining to complement the fabric lining of the lid containment volume.
The lid 120 comprises a second recessed portion 185 between the upper protruded portion 170 and a top edge of the lid 120. The lid 120 also comprises a top stepped portion 180 that is substantially perpendicular to the lid opening plane 125. The second recessed portion 185 extends out from the lid opening plane 125 to a lesser degree than the lower protruded portion 150 and the upper protruded portion 170.
A second aperture 181 is located in the top stepped portion 180. With reference to
The upper pocket 182 comprises a second fabric receptacle having a second receptacle opening, the second receptacle opening having a first side and a second side. The first side is fastened to the moulded shell on a first side of the second aperture 181 towards a front of the second recessed portion 185 and the second side of the second receptacle opening is fastened to the moulded shell on a second side of the second aperture 181 towards a rear of the second recessed portion 185.
The second receptacle opening is closable by a second pocket zipper having a primary zipper tape on the first side of the second receptacle opening and a secondary zipper tape on the second side of the second receptacle opening, such that both the second aperture and the second fabric receptacle are openable and closable by the second pocket zipper.
The primary zipper tape may be fastened to the moulded shell by stitching and the secondary zipper tape may be fastened to the moulded shell by stitching.
In this way the stitching of the primary zipper tape and the secondary zipper tape to the moulded shell not only provides the functionality of opening and closing the upper pocket via the second pocket zipper but also provides the functionality of retaining the second fabric receptacle in position.
The second fabric receptacle may be not otherwise fastened to the first moulded shell. This reduces manufacturing steps and costs. If the lid containment volume is provided with a fabric lining then the second fabric receptacle may be located between the moulded lid and the fabric lining so as to provide some restriction of movement of the second fabric receptacle beyond the stitching around the zipper tapes.
By providing the second aperture 181 in the top stepped portion 180, it more discrete than would be the case if it were in the front face and also the stitching and zipper is less vulnerable to damage from handling such as in airport luggage handling areas.
Furthermore, the upper pocket 182 lends itself well to receiving and accommodating the kinds of items, like laptop computers and tablets, that travelers like to be accessible in an exterior pocket rather than in the main body of the luggage.
The lid 120 may further comprise a plurality of strengthening ribs 121, 122, 123 in the form of shallow linear indentations in a front surface of the lid. In the first embodiment of the suitcase 100 according to the disclosure, the strengthening ribs 121, 122, and 123 are all perpendicular to the sides of the suitcase.
In alternative arrangements, the first aperture 161 and/or the second aperture 181 are located elsewhere on the moulded lid portion.
In alternative arrangements, closure of the lower pocket 162 and the upper pocket 182 may be provided other than by zippers. For example, closure may be provided by one or more of the following: a magnetic clasp, a button tab, a snap fastener, or any other suitable closure.
The suitcase 200 of the second embodiment differs from the suitcase 100 of the first embodiment in a number of ways. The description that follow focuses on the differences relative to the suitcase 100 of the first embodiment.
The suitcase 200 comprises a first protruded portion 250 and a second protruded portion 270 both of which extend substantially out from the lid opening plane. Whereas for the suitcase 100 of the first embodiment the first aperture 161 is located on the lower stepped portion 160, in the suitcase 200 of the second embodiment the first aperture 261 is located on a front face of the first protruded portion 250. Similarly, the second aperture 281 of the suitcase 200 is located on a front face of the second protruded portion 270 rather than on the top stepped portion 180.
Secondly, the lower stepped portion 260, the upper stepped portion 275 and the top stepped portion 280 protrude from the lid opening plane at a gentle acute angle, whereas the equivalent stepped portions in the suitcase 100 project at an angle that is approximately perpendicular to the lid opening plane.
Furthermore, there is no distinct change in radius between the lower stepped portion 260 and a front face of the first protruded portion 250. Rather, the radius is fairly continuous. Similarly, there is no distinct change in radius between the upper stepped portion 275 and the front face of the second protruded portion 270 or between the top stepped portion 280 and the front face of the second protruded portion 270.
Also, relative to the suitcase 100 of the first embodiment, there is a larger radius between the lower edge 255 of the first protruded portion 250 and the front face of the first protruded portion 250.
In this way, the overall profile of the font face when viewed from the side avoids the appearance of corners between the first protruded portion 250, the first recess 265 and the second protruded portion 270.
Finally, the suitcase 200 comprises a larger number of strengthening ribs 222 than the suitcase 100 of the first embodiment. Moreover, the strengthening ribs 222 are curved. In addition, the first aperture 261 and the second aperture 281 are parallel to the curves of the strengthening ribs 222.
Alternative strengthening rib configurations and aperture configurations fall within the scope of the disclosure. For example, the apertures and/or the strengthening ribs may be inverted relative to what is shown in
Also falling within the scope of the disclosure are embodiments having more than two protruded portions thus providing more than two pockets.
In addition, the moulded concave shell may comprise embossing for either or both of structural and aesthetic reasons.

The method comprises moulding the lid 120 comprising a concave shell to include a lower protruded portion 150 which protrudes from the lid opening plane 125 via a lower stepped portion 160 and an upper protruded portion 170 which protrudes from the lid opening plane 125 via an upper stepped portion 175 that faces the lower stepped portion 160.
The method further comprises making an incision to provide a first aperture in the moulded concave shell that provides access to the lower pocket within the lid containment volume behind the lower protruded portion. The method further comprises making an incision to provide a second aperture in the moulded concave shell that provides access to an upper pocket within the lid containment volume behind the upper protruded portion, wherein the upper pocket is in part bounded by an interior surface of the upper stepped portion.
The method further comprises fastening a hinge between the body and the lid to enable movement of the lid relative to the body between: an open position in which the body and lid containment volumes are accessible through the body and lid openings; and a closed position in which the body and the lid openings cooperate such that the body and lid containment portions are enclosed.
In some embodiments, the upper and lower stepped portions are substantially perpendicular to the lid opening plane.
In some embodiments, the moulded concave shell further comprises a first recessed portion between the upper and lower stepped portions and set back from the upper and lower protruded portions.
In some embodiments, the concave moulded shell further comprises a second recessed portion that is set back from the upper protruded portion and substantially perpendicular to the lid opening plane, and a top stepped portion on an opposite side of the upper protruded portion from the upper stepped portion, wherein the second aperture is located in the top stepped portion.
In some embodiments, the method also comprises providing a first fabric receptacle having a first receptacle opening the first receptacle opening having a first side and a second side, then fastening the first side of the first receptacle to the moulded shell on a first side of the first aperture and fastening the second side of the first receptacle to the moulded shell on a second side of the first aperture.
The method may further comprise: fastening a first pocket zipper having a first zipper tape and a second zipper tape to the lid. In particular, the first zipper tape may be fastened on the first side of the first receptacle opening and the second zipper tape may be fastened on the second side of the first receptacle opening, such that both the first aperture and the fabric receptacle are openable and closable by the first pocket zipper.
In some embodiments, any one or more of the fastening steps may comprise stitching.
