Benefits of technology

[0013]It has been found that this proportion of openings in the sleeve provides particular benefits regarding the kinetics of moisture absorption by the desiccant arrangement as required in a closed container. Containers are exposed to considerable environmental temperature changes, for example temperature changes caused during the day by considerable warming by sunlight during the day to much cooler temperature at night or temperature changes caused by transportation of the container from tropic subtropic climate zones to more arid climate zones. These considerable temperature changes are reflected by considerable changes in the relative humidity of the atmosphere in the container. The preferred proportion of openings in the sleeve surface allow an optimal and rapid access of the moisture to the desiccant in the desiccant arrangement in order to avoid the undesired condensation of water on the container wall or goods present in the container.
[0014]According to a further embodiment the openings are of round or rectangular shape and have a diameter of at least 0.5 cm, preferably at least 1.0 cm, more preferred at least 2 cm. Particularly preferred the diameter of the openings is selected within a range of 0.5 to 4 cm. By providing openings of large diameter an easy gas exchange between the interior of the sleeve and the surrounding is achieved. The transportation of humidity within e.g. a closed container is for the most based on diffusion processes and to a small amount on convection. Therefore it is preferred to provide an easy access of the humidity to the desiccant arrangement but at the same time to provide sufficient stability to the protective sleeve such that the desiccant container may be easily handled without a danger to rip or destroy the protective sleeve.
[0016]Preferably, the operatively front panel includes a plurality of spaced groups of openings. Optionally, an operatively rear panel may also include openings which may also be arranged in groups. The openings are preferably arranged in one or more groups or patterns spaced apart on the surface of the protective sleeve. More preferred, the groups of openings are in the shape of one or more regular patterns, in particular rectangular patterns, spaced from each other on the surface of the sleeve. By arranging the openings in groups, larger areas of solid material are obtained in the protective cover thereby increasing the stability of the protective sleeve.
[0018]According to a preferred embodiment side panels are arranged between front panel and rear panel to obtain a rectangular tube. Such arrangement in a box shape allows an increase in volume of the protective sleeve and therefore allows an increase in the amount of desiccant that may be placed inside the protective sleeve.

Problems solved by technology

When humidity is adsorbed by the desiccant arrangement, the desiccant will gain weight.

third embodiment

[0076]FIG. 5 shows a schematic, three dimensional view of a desiccant container 100, in accordance with the invention. Desiccant container 100 comprises a protective sleeve 101 of a box-like shape. Protective sleeve 101 is made of corrugated cardboard and comprises rear panel 102 and front panel 103 (not visible) arranged opposite to each other. Front panel 103 and rear panel 102 are connected by side panels 104 such that a tube having a rectangular cross-section is obtained. In front panel 103 as well as rear panel 102 are provided openings 105 which allow access of humidity to the interior of protective sleeve 101. Openings 105 are arranged in groups 106 which comprise three subgroups 107 formed of 6 openings 105 each. Further are provided in rear panel 102 two slots 108 to receive tabs 109 in an interlocking relation.

[0077]Along an edge 114 of front panel 103 are provided two separate flaps 110 in a side by side configuration defining a narrow slot 111 between them. Each of flaps...

first embodiment

[0087]In FIG. 7a, b is shown the hanger to be used with the desiccant container according to the invention. FIG. 7a displays a perspective view whereas FIG. 7b is a view onto one side of the hanger. The hanger generally designated as 135 comprises a bar 136 made of a stiff material, e.g. metal or reinforced plastic. Centrally on bar 136 is mounted a hook 117, e.g. by welding. Bar 136 is thereby divided into two shoulders 137a and 137b each having the same length. Hook 117 is oriented orthogonally towards bar 136. This can also be seen from FIG. 7(b) which is a view along the axis formed by bar 136. Hook 117 comprises a straight leg 138 extending from bar 136. Straight leg 138 is continued by a first arcuated section 139 which is bent in a direction towards straight leg 138. First arcuated section 139 is continued by a second arcuated section 140 having a curvature opposite to the curvature of first arcuated section 139. Thereby together with straight leg 138 is formed a bottleneck w...

second embodiment

[0088]FIG. 7(c) is a perspective view of a hanger to be used for the desiccant container according to the invention. Hanger 135 comprises a hook 117 having a similar shape as the hook explained with the embodiment of FIG. 7(b) above. Mounted to straight leg 138 of hook 117 is a bent bar 141 comprising a shoulder 142 which is continued after a turn 143 by a straight section 144. Hook 117 is situated at about the center of straight section 144 and is oriented orthogonally to shoulder 142 and straight section 144.

[0089]FIG. 8 (a, b) shows top views of desiccant arrangements 154 to be used with a desiccant container according to the invention.

[0090]FIG. 8 (a) shows an embodiment of a desiccant arrangement 154 that may be used e.g. together with a hanger as depicted in FIG. 7a. The desiccant arrangement comprises pouches 145 which accommodate a desiccant. Pouches 145 are arranged side-by-side in a longitudinal and transversal directions thereby forming a blanket. Adjacent pouches are joi...

Abstract

The invention is directed to a desiccant container which includes—a hanger element (12, 135) for suspension in a zone from which it is desired to remove moisture; a desiccant arrangement (14, 154) comprising at least one moisture permeable receptacle containing a supply of desiccant, the desiccant arrangement being—suspended from the hanger element (12, 135); and a flexible protective sleeve (18, 101), at least a part of which is moisture permeable, arranged about the desiccant arrangement (14, 154), wherein the sleeve is mounted on the hanger element (12, 135) independently from the desiccant arrangement.

Description

[0001]This invention relates, generally, to moisture removing devices and, more particularly, to a desiccant container for the removal of moisture from the environment. The invention has particular, but not necessarily exclusive, application in ISO transport containers.BACKGROUND TO THE INVENTION[0002]In the transportation of goods through different climatic zones, there is a danger of the goods being transported being spoiled as a result of the build up of moisture. This danger is especially pronounced in the case of ISO transport containers which may be shipped into and out of humid zones such as tropical areas.[0003]To counteract this problem, use is made of desiccant containing covers or linings used in the interior of the containers. Such covers or linings at least partially ameliorate the situation but are expensive and there is therefore a desire to re-use them. The Applicant is aware of a container which can be suspended from a wall of the ISO container. This container, howe...
