Description

Title: Method for the air-tight, water-tight and/or gas-tight sealing of an end of a tube Description The present invention relates to a method for air-tight, water-tight and/or gas-tight sealing of an end of a tube.
The present invention further relates to a seal suitable for use in the method of the present invention as well as to a tube provided with a seal obtainable by the method of the present invention.
The sealing of the ends of tubes is a well-known technique in the art.
However, the sealing of the ends of tubes in an air-tight, water-tight and/or gas-tight manner is often a cumbersome and complex process.
In order to improve such process the present invention provides hereto, in a first aspect of the invention, a method for the air-tight, water-tight and/or gas-tight sealing of an end of a tube, the method comprising the steps of: 3) providing a tube with an open end; b) providing a seal configured for placement in the open end of the tube provided in step a); and Cc) placing the seal in the open end of the tube, wherein the seal comprises an insert with an outer perimeter selected such that the insert is receivable in the open end of the tube, and wherein one of the ends of the insert is connected to a closing element for closing the one end of the insert, and wherein the closing element has a perimeter that is at least equal to the inner perimeter of the tube.
The insert is further provided on the outside with a circumferential recess for forming a gap between the inner wall of the tube and the seal placed in the tube, such that the method of the present invention enables the further step of: d) after placing the seal in step c), feeding a sealing material into the gap formed by the recess.
It was found that by providing the method of the present invention, an air-tight, water-tight and/or gas-tight sealing of an end of a tube can be provided in an simple and reliable manner.
It is noted that the tube may be a cylindrical tube.
In case a cylindrical tube is provided, the insert of the invention is cylindrical as well.
It is further noted that the term ‘perimeter’ may be replaced by ‘diameter’ in case of a cylindrical tube and corresponding insert. Alternatively, the tube may have a cross-section that is in the form of a square or rectangle. However, other forms are possible as well.
The feeding of a sealing material into the gap formed by the recess of the insert may be carried out by injecting the sealing material into the gap formed by the recess. In order to facilitate the injection of the sealing material into the gap formed by the recess, the closing element and insert may be provided with a through- opening debouching in the gap formed by the recess of the insert. Alternatively the sealing material may be injected into the gap formed by the recess using an injection tool for piercing the closing element and insert or that part of the tube whereof the inner wall is part of the gap formed by the recess.
The sealing material may be a curable material, e.g. a thermoplastic material or adhesive. In an embodiment of the present invention, the sealing material may be a two-component adhesive wherein both components come into contact with each other when fed to the gap (e.g. by injecting both components simultaneously).
However, other suitable curable materials may be used as well. For example, the sealing material may be selected from the group consisting of expansion resins, such as, for example, a poly urethane mixture commercially available under the name Tangit M 3000 (Henkel).
In a second aspect of the present invention, the present invention relates to a seal suitable for use in the method of the present invention. The seal may comprise a insert being a hollow insert. By providing a hollow insert, the seal of the present invention can be placed into the open end of a tube in a simple and reliable manner. Further, a hollow insert provides some flexibility to the insert further improving the easiness to place the seal into the open end of a tube. However, alternatively, the insert may also be made of a solid insert.
The insert may be made of a flexible material, preferably a flexible plastic material. The closing element may be made of a more rigid material, preferably a rigid plastic material. However, the closing element and insert forming the seal of the present invention may also be made of the same material, e.g. a flexible material.
The outer perimeter of the insert may be chosen such that the insert is configured for clampingly receiving the insert in the tube. Preferably, the outer perimeter of the insert is equal or slightly smaller than the inner perimeter of the tube in which the seal of the present invention is to be placed. In case the insert is made of a flexible material, the outer perimeter of the insert may be even slightly larger than the inner perimeter of the tube in which such seal is to be placed. By clampingly receiving the insert in the tube, a preliminary pre-sealing of the open end of the tube is obtained before improving the sealing provided by the seal of the present invention by feeding the sealing material into the gap formed by the recess of the seal.
Although the circumferential recess of the seal of the present invention may have different dimensions and may be arranged somewhere in the outer surface of the insert of the seal, the circumferential recess may be a centred circumferential recess relative to the width of the insert.
The circumferential recess may further have a width that is between is between 50% and 90% of the width of the insert. Preferably the width of the circumferential recess is between 60% and 80% of the width of the insert. More preferably, the circumferential recess is about 70% of the width of the insert. By providing a circumferential recess having a width that is relatively high compared to the total width of the insert, an insert is provided wherein the ends of the insert are provided with outwardly projecting flanges. Given the thickness of the flanges and given the material used for making the insert, the dimensions of the circumferential recess may be selected such that the outwardly projecting flanges have a certain flexibility and a certain sturdiness suitable for the intended use.
Besides varying the width of the circumferential recess, for example in order to design an insert having a certain flexibility and certain sturdiness, also varying the depth of the circumferential recess may play an important role in facilitating placement of the seal of the present invention into an open end of a tube. The depth of the circumferential recess in for example a cylindrical insert may be between 2% and 12% of the outer diameter of the cylindrical insert. Preferably the circumferential recess may be between 4% and 10% of the outer diameter of the cylindrical insert or between 6% and 8% of the outer diameter of the cylindrical insert. More preferably the circumferential recess may be about 7% of the outer diameter of the cylindrical insert. Analogously, the same depth of the circumferential recess may be applied to other forms of the insert as well, other than a cylindrical insert.
In a third aspect, the present invention relates to a tube wherein at least one end is provided with a seal obtainable by the method of the present invention. Preferably, the tube may have two open ends, wherein not only one end is provided with a seal according to the method of the present invention, but also the second end of the tube is provided with a seal obtainable by the method of the present invention.
The present invention herewith provides an air-tight, water-tight and/or gas-tight sealed tube.
The invention will now be explained in more detail with reference to an exemplary embodiment shown in the appended figures, in which: Figure 1 shows a perspective view of a seal of the present invention; and Figure 2 shows a cross-section of a sealed tube using the seal and the method of the present invention.
Figure 1 shows a perspective view of a seal 1 of the present invention.
The seal 1 is made of a cylindrical insert 2 wherein a circumferential recess 3 is arranged.
The circumferential recess 3 may be dimensioned such that a sort of outwardly projecting flange 4 is provided.
Further a closing element 5 is provided on one end of the cylindrical insert 2. The closing element 5 shown in figure 1 has a diameter which is slightly larger than the diameter of the cylindrical insert 2. However, it is noted that the closing element 5 may have an identical diameter as the cylindrical insert 2. Figure 2 shows a cross-sectional view of a sealed tube 10 using the seal 1 of the present invention.
The seal 1 is retained in the tube 10 by the cylindrical insert 2 having an outer diameter which is equal to the inner diameter of the tube 10. The circumferential recess 3 formed in the outer surface of the cylindrical insert 2 is dimensioned such that on both ends of the cylindrical insert 2 outwardly projecting flanges 4 are formed.
Further, the dimensions of the closing element 5 are chosen such that the diameter of the closing element 5 coincides with the outer diameter of the tube 10. Further, figure 2 shows a gap 6 formed by the circumferential recess 3 and the inner surface of the tube 10. In order to provide an air-tight, water-tight and/or gas-tight sealing, the gap 6 is filled with a sealing material injected into the gap 6 via aperture or through-opening 7. In figure 2, the through-opening 7 passes through the closing element 5 and a part of the cylindrical insert 2 (i.e. the outwardly projecting flange 4 in figure 2) in order to debouches in the gap 6 formed by the circumferential recess 3.
