INTEGRAL INNER RIM FOR INJECTION MOULDED HARD-SIDED LUGGAGE CASES
A luggage case including at least one injection moulded shell having an interior region and including a sidewall defining at least in part an integrally formed outer rim and an integrally formed inner rim positioned interior of the outer rim. The inner rim extends along at least a portion of the length of the outer rim, and the inner rim extends at an acute angle away from the sidewall. Support features extend between the outer rim and the inner rim.
1 . A luggage case comprising:
at least one injection moulded shell including a major face panel and at least one sidewall together defining an interior storage volume, the sidewall defining at least in part an integrally formed outer rim and an integrally formed inner rim positioned interior of the outer rim; and
wherein the inner rim extends along at least a portion of a length of the outer rim, and the inner rim extends at an acute angle away from the sidewall.
2 . The luggage case as defined in claim 1 , wherein:
the sidewall extends from along at least a portion of a periphery of the major face panel, the sidewall including at least one corner region and the outer rim defined to at least partially extend along the sidewall and the at least one corner region; and
the inner rim extends along at least a portion of sidewall and along the at least one corner region.
3 . The luggage case as defined in claim 1 , wherein:
the inner rim extends around approximately 50-90 percent of the length of the outer rim.
4 . The luggage case as defined in claim 1 , wherein:
the inner rim extends continuously along a majority of a length of the sidewall.
5 . The luggage case as defined in claim 1 , wherein:
the inner rim extends around an entirety of the length of the outer rim.
6 . The luggage case as defined in claim 1 , wherein:
support features extend between the outer rim and the inner rim.
7 . The luggage case as defined in claim 1 , wherein the outer rim is flush with an exterior surface of at least one sidewall.
8 . The luggage case as defined in claim 1 , wherein:
at least part of the sidewall extends substantially orthogonally from the major face panel.
9 . The luggage case as defined in claim 2 , wherein:
the sidewall includes a top panel and an opposing bottom panel; and
the bottom panel extends from the major face panel at an angle between and including approximately 90 to 98 degrees.
10 . The luggage case as defined in claim 1 , wherein the acute angle between the inner rim and the sidewall is approximately between and including 1 and 14 degrees, or is approximately between and including 4 and 6 degrees.
11 . The luggage as defined in claim 1 , wherein the inner rim is at an angle of approximately between and including 80 and 94 degrees relative to the major face panel.
12 . The luggage case as defined in claim 1 , wherein the at least one shell comprises:
a first portion of the sidewall oriented orthogonal relative to the major face panel and a second portion of the sidewall oriented at an outward angle to the major face panel greater than the first sidewall.
13 . The luggage case as defined in claim 1 , wherein:
the inner rim forms an angled surface for sliding contact with a mould core during removal of the shell from a mould.
14 . The luggage case as defined in claim 1 , wherein:
the inner rim deflects outwardly upon release from a mould core, or the inner rim and outer rim deflect outwardly upon release from the mould core.
15 . The luggage case as defined in claim 1 , further comprising:
at least one wheel mounted on a corner region of a bottom panel of the injection moulded shell; and
a tow handle mounted on a rear main face panel of the luggage shell.
