Description

MOISTURE-ABSORBING DEVICE
TECHNICAL FIELD
The present invention relates to a moisture-absorbing device comprising a lower chamber for collection of liquid and an upper chamber containing a moisture-absorbing agent, the upper chamber displaying a liquid-permeable device for draining liquid absorbed by the moisture- absorbing agent to the lower chamber.
The present invention also relates to a method of producing a moisture-absorbing device comprising the steps that a first hose of liquid-tight, flexible plastic material is produced, and that the hose is cut into predetermined lengths that are sealed in one end.
BACKGROUND ART
A common problem during the colder seasons of the year in, for example, uninhabited recreation and leisure buildings, basements, caravans, freight containers, boats, garages, storage premises, bathrooms or other spaces that are sensitive to damp and moisture is that moisture that creates a stale smell may, in the worst case scenario, lead to fungal attack.
In order to alleviate this problem, a moisture-absorbing device was developed which is disclosed in SE 9801866-6. This moisture-absorbing device includes an elongate tube of flexible plastic which extends along the entire length of the moisture-absorbing device. This tube is closed at its lower end. The elongate tube has an upper chamber and a lower chamber. The upper chamber and the lower chamber are separated off by a grid arrangement. Inside the upper chamber, a moisture-absorbing material is accommodated in a filter hose consisting of an air- and liquid-permeable material. The lower chamber serves the function of a liquid- collecting device. The tube has an opening flush with the upper chamber, the filter hose with the moisture-absorbing material being placed in register with this opening. The moisture- absorbing material is calcium chloride and absorbs moisture through the opening of the tube and leads the moisture down to the liquid-collecting device. In one embodiment, the tube displays a whole rear surface in order that the moisture-absorbing device will be able to be suspended against a wall without giving rise to damp attack on wallpaper or the like, or even corrosion attack if the device is, for example, suspended in a freight container. In a further development of the above-described moisture-absorbing device, the elongate tube has round through-going foraminations or perforations on both the front and rear sides of the upper chamber.
The above-outlined device is an acceptable solution from the point of view of production engineering but suffers from the drawback that' it cannot be suspended against a wall, since the device then transfers absorbed moisture as a saline solution direct to the wall, with damp attack and damage as a result. If the device is suspended in a corrosion-sensitive space, the saline solution will corrode the wall.
The drawbacks inherent in the above-described embodiments are further that the air exchange in the space involved will not be optimal, since the elongate tube adheres to the filter hose and by such means reduces the moisture absorbing area, in which event the air exchange with the ambient air is limited to the area of the opening/openings of the elongate tube.
PROBLEM STRUCTURE
The presn4et invention has for its object to design the moisture-absorbing device intimated by way of introduction so that it obviates the drawbacks inherent in prior art methods and devices* In particular, the present invention has for its object to design the moisture-absorbing device in such a manner that it may be adapted in size in a very simple manner so that, in terms of construction, it will be simpler, and may also be manufactured with less material consumption.
SOLUTION
The objects forming the basis of the present invention will be attained if the moisture- absorbing device described by way of introduction is characterised in that the upper chamber is in the form of a bag which at least partly consists of a material which is permeable to air and liquid, and a lower portion of the bag is disposed interiorly in an upper mouth portion of the lower chamber and is secured there for interconnection of the chambers.
The objects forming the basis of the present invention will be attained in respect of the method if the method disclosed by way of introduction is characterised in that that a second hose is produced, the second hose being formed from a first and second material, where the first material is liquid-tight and the second material is air- and liquid-permeable, and the materials extend throughout the entire length of the second hose, that the second hose is cut into predetermined lengths which are sealed at one end so that a bag is formed, that the bag with the closed end is passed into and fixed in an open end or mouth region of one length of the first hose and the bag is filled with a moisture-absorbing agent.

DESCRIPTION OF PREFERRED EMBODIMENT
In the description given below, directional and positional indications will be employed such as upper, lower, front and rear. These relate to a situation which is normal for the use of the device according to the present invention, for example in the suspension of the device ^according to the present invention in a space.
Fig. 1 shows a moisture-absorbing device which has a lower chamber 1 and an upper chamber 2. The lower chamber 1 acts as a liquid-collector and the upper chamber 2 contains a moisture-absorbing agent 3, for absorbing moisture and condensation which is to be found in the air in a damp space. The upper chamber 2, which is shown in cross section in Fig. 2, has a liquid-permeable device 4 for draining the liquid absorbed by the moisture-absorbing agent 3 to the lower chamber 1.
The upper chamber 2 is in the form of a bag 5 which at least partly consists of a first material 6 which is permeable to air and liquid, and a second material 7 which is air- and liquid-tight, see Fig. 2. A lower portion 8 of the bag 5 is disposed interiorly in an upper mouth portion 9 of the lower chamber 1 and is secured there for interconnection of the upper chamber 2 to the lower chamber 1. The outer width dimension of the upper chamber 2 is slightly less than the inner width dimension of the lower chamber 1.
When the bag 5 is flattened and without the moisture-absorbing agent 3, it has a front side 10 and a rear side 1 l.The rear side 11 consists of the air- and liquid-tight material 7 for possible abutment against the surrounding surfaces 12 of a space, and the front side 10 consists of the air- and liquid-permeable material 6 through which the moisture-absorbing agent 3 may absorb moisture and condensation.
The moisture-absorbing agent 3 has a capacity to bond moisture in the air and is preferably a salt or a salt compound such as, for example, magnesium chloride, whereafter the absorbed liquid dissolves the magnesium chloride and forms a saline solution which runs down into the lower chamber 1.
The liquid-permeable device 4 includes a part of the air- and liquid-permeable material 6 of the bag located at the lower end portion 8 of the bag.
The air- and liquid-permeable material 6 is a flexible, perforated plastic material or a "non- woven" material which allows the passage of liquid both from the inside and outwards and from the outside and inwards. The air- and liquid-tight material 7 also consists of a flexible plastic material. The air- and liquid-permeable material 6 and the air- and liquid-tight material 7 are both weldable and manufactured from polypropylene.
The lower portion 8 of the bag 5 is interiorly secured in the upper mouth portion 9 of the lower chamber 1 by means of welds at the longitudinal opposing edges 15 of the chambers 1 and 2, respectively. The fixing of the bag 5 to the lower chamber 1 contributes to the formation of openings 16 on both the front side 10 and the rear side 11 from which excess saline solution may be emptied in order not to run the risk that this solution is unintentionally spilt on movement of the moisture-absorbing device.
In its upper end, the bag 5 has a suspension device 17 which is preferably in the form of a hook or a catch.
The moisture-absorbing device is produced by means of a process which comprises a number of steps, a first hose 18 being produced from an air- and liquid-tight, flexible plastic material
1. The hose 18 is unreeled from a magazine reel 22 and is cut into predetermined lengths L, as shown in Fig. 3, which are closed by welding in one end. The cutting and welding may preferably be put into effect in the same working cycle. The first hose 18 may also be formed from two liquid-tight band-shaped materials which are welded together, the welding joints or seams 20 which are shown in Fig. 4 being formed along the longitudinal sides and along the one end.
A second hose 19 is produced, this being formed from a first and second band-shaped material 6 and 7, respectively, which are welded together, welding joints or seams 21 which are shown in Fig. 4 being formed along the longitudinal sides and along the one end. The first material 6 is air- and liquid-permeable, while the second material 7 is air-and liquid-tight and the materials 6 and 7, respectively, extend throughout the entire length of the second hose 19. The second hose 19 is also cut into predetermined lengths L, which are closed by welding in one end so that a bag 5 is formed.
The bag 5 with the closed end is moved into and fixed in an open mouth or end portion 9 of a length of the first hose 18 which is shown in Figs. 4 and 5, the bag 5 and the first hose 18 overlapping. The first hose 18 and the bag 5 are secured together by means of welded seals 14 along opposing longitudinal sides 15, the open end portion 16 substantially remaining on the first hose 18.
In the next step, the bag 5 is given a filling of a moisture-absorbing agent 3 which is shown in Fig. 6, whereafter the open end 23 of the bag 5 is secured on a suspension device 17 as shown in Fig. 7, whereafter the entire moisture-absorbing device is packed in closed outer transport casing for avoiding the risk that the moisture-absorbing agent begin to absorb moisture before the moisture-absorbing device has been made operational.
The method according to the present invention makes it simple to manufacture the upper chamber 2 and the lower chamber 1 in the desired lengths regardless of whether the moisture- absorbing device is to be manufactured with small or large capacity.
