GB2462485A - Drying system comprising a bag with a permeable layer - Google Patents

Abstract

A drying system in the form of an item of hand luggage for transporting wet gear wet suits, fishing gear, sports gear, sailing gear, washing, clothes, camping gear, tents, wet fabrics or the like without allowing moisture into a carrying vehicle comprises a first, at least selectively permeable, bag located within a second, impermeable, bag such that items to be dried are placed into the first bag and moisture moves form the first bag into the second bag. Preferably, the inner bag comprises a semi-permeable membrane 30,130 and/or a breathable fabric that in use passes water in a single direction from the inner bag to the outer bag. The outer bag may comprise a reservoir 40 that stored moisture removed from the inner. In use, the drying system can dry wet gear of all sorts indoors or out of doors, including out of doors in the rain.

Description

The Wet and Dry Bag This invention provides a solution to the prolalem of carryrng wet gear (wet suits, fishing gear, sports gear, sailing gear, washing. domes, camping gear, tents, etc.) wnhout allowtng moisture into a carrying vehicle or dry other area hut whilst actively drying the gear ta quesnon inside the Wet and Dry Bag or similar drying systent Tn another application the punciple can be applied to diTing items out of doors inside a suitable hag or system, regardless of weather conditions. This is a very real problem in wet climates such as for example the UK, Europe and the USA and for those who practise water related sports such as surfing, sailing, fishing etc. The principle consists of using a semi-permeable membrane material such as Gore-Tex (RTM or material of similar properties which allows water to pass in one direction only as a scparator between the wet gear compartment and another compartment(s) and/or a breathable material such as Tyvek (RTM or material of similar properties asas eparator between compartments or compartments arid the 0) outsrde atmosphere.

0 fri one apphcation the senii-pemeable membrane separates two compartirients 0 within a cwate11root hag or drying s stern Figure 1. The wet gear is placed iii the r upper compartment, whjeh has wails of breathable fabric such as Tyvek çR'TTh/ or matehai of similar properties and: the water collects selectively in the lower waterproof compartment by passing through the semi-permeable membrane, Thus wet gear can be placed in the upper bag, and the whole hag then transported for example by car, without moisture passing out to the vehicle whilst the contents are actively dried lay passing water into the lower compartment by way of the semi-permeable membrane. Water can then be drained off as rec1ired via the valve. The bag or system can also he hung outside to dry the contents, via the l:aeathable nature of the Tyvek (RTM. Bags or systems can be soft or rpld, or indeed the membrane system can be incorporated into a rigid box structure to give stackable units for transport of multiple separate items and gear, Figure 2 and Figure 3.

fri another application a hag or drying system cart be constructed as a single compartment using a breathable fabric such as Tvyek (RTM or material of sitnilar properties such that moisture can pass out of the bag without eotiderising itiside. Thus wet gear can be placed in the hag and the bag then hung out of doors to dry the gear, regardless ot the weather condruons. Even in falling rain the interior contents of the bag will be effectively dried, Figure 4.

Other appilcation of this principle for the drying of wet gear and articles of all types using jtems and containers constructed from similar materials will he obvious for anyone involved jn similar activities and to those skilled in the art and construction of similar items, and in particular, to those in sporms, garments, storage and baggage related indu stnes. 0*) r r

Claims (6)

1. Claims The following claims are examples of the Wet and Dry Bag principle and utilisation is not limited to these specific claims, Other applications of the wet and dry hag principle to drying systems will he obvious to others and in particular to those in sports, garments, storage and baggage related industries.1. The use of a semi-permeable membrane such as Gore-Tex (RT]\'l or material of similar propemnes which allows water to pass in one direction only as a separator between the wet gear and. another compartment(s, tn a drying bag or drying system, Figure 1.
2. 2. The use of a breathable material such as Tyvck (RTMi or material of similar properties as a separator between compartments or between cotrttartmnents and the outside atmosphere in a drying hag or drying system Figure 2, 3 arid 0) 0
3. 3. The construction of a drying bag or dryfng system as iii Figure 1, to allow r / the transport of wet gear (wet suits, fishing gear, sports gear, sailing gear, washing, clothes, camping gear, tents, wet fabrics or machinen etc.) without allowing motsture into a carrying vehicle or other dry area hut whdst actively drying the gear in question nsde the hag or drying system by passage of water into a scaled compartment.
4. 4. Construction of a drying laag or drying system as in Figure 4 to allow the dryityg of wet gear of all types, especially out of doors, regardless cf the weather conditions.
5. 5. The use of drying bag or drying system as in Claim 3 for the drying and storage arid transportation of wet items, thr example but not limited to: wet suits, fishing gear, sports gear, sailing gear, washing, clothes. camping gear, tents, wet fabrics or machitiery, etc.
