[0001] Endless fire protection strips for a fire barrier and fire barrier
[0002] The invention relates to an endless fire protection strip for a fire barrier and a fire barrier.
[0003] Fire barriers must be installed around external thermal insulation to prevent fire from spreading from a window to the next floor. Vertical fire barriers typically align with the ventilated facade. In contrast, horizontal fire barriers allow air circulation by providing a gap to the facade. Especially when ventilated facades are installed, the gap required for ventilation must be sealed in the event of a fire to prevent fire spread for a sufficient period. For this purpose, fire barriers have a base section filled with insulating material and a sealing section filled with intumescent material that expands in the event of a fire, thus closing the gap.
[0004] Fire barriers are generally available in a wide range of thicknesses, depending on the distance between the facade cladding elements and the substrate. Due to the diversity of facades used and the multitude of different insulation thicknesses, manufacturers must therefore maintain a large number of differently dimensioned fire barriers, which results in significant manufacturing and storage costs.
[0005] An additional complication arises when the distance between the facade and the substrate varies somewhat more significantly. This variation in distance means that a single nominal thickness (relative to the distance between the substrate and the facade) is insufficient to keep the gap sufficiently small to comply with fire safety regulations.
[0006] The product can usually be adjusted to a smaller gap. However, if the gap is larger than planned, a new product must be reordered. This slows down the timeline for such facade work. The problem is exacerbated by architecturally appealing, unusual (sloped) facades. In these cases, the adjustment requires a significant amount of manual labor or frequent reordering.
[0007] The invention is therefore based on the object of providing a continuous fire protection strip and a fire barrier that can eliminate or at least reduce the disadvantages of known fire barriers. In particular, the respective fire protection regulations should be reliably met. Furthermore, the requirements of a multitude of different manufacturing geometries and the high storage costs should preferably be avoided as much as possible. Furthermore, the installation effort of the fire barrier should preferably be low for the user or installer.
[0008] The problem is solved by the subject matter of the independent patent claims. Advantageous embodiments are specified in the dependent patent claims and the following description, each of which, individually or in (sub)combination, may represent aspects of the invention.
[0009] According to one aspect, a continuous fire protection strip for a fire barrier is provided. The continuous fire protection strip comprises a sealing section that at least partially comprises an intumescent material. The continuous fire protection strip also comprises at least one first fastening section laterally adjacent to the sealing section. The continuous fire protection strip can be fixed to a base strip of the fire barrier, at least by means of the first fastening section.
[0010] The continuous fire protection strip thus constructed advantageously allows for separation from the sealing material (base strip of the fire barrier) used to insulate the façade. This allows the continuous fire protection strip to be produced and used independently of the sealing material. This eliminates the need to accommodate the multitude of different production geometries required for different applications due to varying distances between the façade cladding elements and the substrate. A continuous fire protection strip with uniform dimensions can be produced, regardless of the application (at least regardless of the distance). Furthermore, storage costs for the continuous fire protection strip are reduced. Since it is produced independently of the respective insulation material, its dimensions are smaller, thus advantageously reducing the space required.
[0011] Independence from the insulation material also has advantages for the end user or installer. If the insulation material forms a composite with the fire protection strip, in the event of an individual mismatch (error in cutting), the usability of the entire unit, i.e. the insulation material and the fire protection strip, is prevented. This results in high costs, even though the error is usually due to a mismatch of the inexpensive insulation component of the overall unit and not the cost-intensive fire protection strip itself. However, since the invention uses both components separately, an incorrect cutting results in only the less expensive insulation material having to be re-cut. The endless fire protection strip according to the invention can nevertheless also be used with the newly adapted component of the insulation material, at least provided the error is detected before the two are irreversibly coupled.
[0012] Furthermore, incorrect cutting does not cause any delays in the facade work. Because the continuous fire protection strip is separated from the insulation material, a mismatch does not require a new unit to be ordered from the manufacturer. Rather, only a new unit of insulation material needs to be adjusted, which is typically always available on site for such work. Obtaining a new fire barrier (i.e., the combination of insulation material and fire protection strip), which is known to lead to delays in the work, can be advantageously avoided.
[0013] The sealing section refers to the section of the continuous fire protection strip containing the intumescent material. The intumescent material expands in the event of a fire, sealing the gap intended for rear ventilation. This prevents the flames from spreading between different areas in opposite directions of the gap.
[0014] In this case, the base strip of the fire barrier can be understood as a base component comprising an insulating material, which is arranged between the substrate (building part) and the facade elements. The base strip of the fire barrier thus spans a partial distance between the substrate and the facade elements in the direction perpendicular to the respective facade element. A further partial distance is spanned by the sealing section adjoining the base strip of the fire barrier in the direction perpendicular to the respective facade element. A remaining partial distance remains along the direction perpendicular to the facade element, which corresponds to the gap provided for rear ventilation.
[0015] In the present context, "latterly adjacent" can be understood as a positioning that extends in a direction that, in the application, is essentially parallel to the respective facade element. This means that "latterly adjacent" does not refer to a direction that is perpendicular to the respective facade element. However, the fastening section does not necessarily have to extend along this direction, but merely border the sealing section along this direction. Therefore, "latter adjacent" should not be understood to mean that the fastening section cannot extend essentially along the direction perpendicular to the respective facade element in the application situation.
[0016] The continuous fire protection strip preferably has a second fastening section. The first and second fastening sections can be laterally adjacent to the sealing section on opposite sides. In other words, the first and second fastening sections border the sealing section in opposite directions within a plane that is oriented substantially parallel to the respective facade element. The plurality of fastening sections can improve the fixation to the base strip of the fire barrier.
[0017] Optionally, at least the first fastening section has a first surface and a second surface opposite the first surface. At least one of the two surfaces is coated with a fastening agent. The use of a fastening agent enables easy handling yet reliable fixation to the base strip of the fire barrier.
[0018] The fastening means preferably comprises an adhesive. In a particular embodiment, the sealing section further comprises, at least in part, an elastic sealing material into which the intumescent material is embedded. For some applications, gaps between the substrate and the respective facade element must be avoided. In this case, the elastic sealing material, within the scope of the elasticity of the sealing material, ensures flexibility during installation between the substrate, or the base strip of the fire barrier, and the facade element. In other words, the elasticity of the sealing material provides a certain amount of play regarding the distance, thus facilitating installation.
[0019] In particular, the elastic sealing material can also be compressible. This makes the sealing section even easier to install.
[0020] The sealing material preferably comprises a foam. The foam can be open-cell or closed-cell. Foams are well suited to providing elasticity and compressibility.
[0021] The sealing material is optionally available as a fire-retardant or non-combustible material, which can improve safety in the event of a fire.
[0022] In a special embodiment, the outer surfaces of the sealing section are laminated with a film, at least along the longitudinal direction of the continuous fire protection strip. The film lamination ensures durability during installation. This prevents the sealing section or its material from being damaged during manufacturing or installation. Furthermore, the film protects against condensation, thus providing permanent protection for the sealing material.
[0023] In the present case, “along the longitudinal direction of extension” can be understood as an extension which encompasses at least the end faces of the sealing section along the longitudinal direction of extension, both in relation to the surface which lies opposite the respective facade element and in relation to the surface which lies opposite the base strip of the fire barrier.
[0024] Optionally, the continuous fire protection strip is also available along its lateral
[0025] Expansion is covered with the film. This means that the end faces, which are essentially parallel to the respective facade element during installation, are covered with the film both along the length and across the width of the fire protection strip. Furthermore, outer surfaces of the sealing section, which are essentially perpendicular to the respective facade element, can also be covered with the film.
[0026] The film preferably has a lattice structure. More preferably, the lattice structure comprises a rectangular lattice structure or a diamond lattice structure. Lattice structures exhibit increased strength along the sections that define the lattice. Therefore, lattice structures can further improve the film's resistance to external influences.
[0027] In one embodiment, an underside of the sealing section has a first outer surface. An upper side, opposite the underside and arranged parallel, has a second outer surface opposite the first. The height of the sealing section (DAH) between the underside and the upper side can then be between at least 4 mm and a maximum of 50 mm, preferably between at least 15 mm and a maximum of 30 mm, more preferably essentially 20 mm. In use, the underside and the upper side of the sealing section are oriented essentially parallel to the respective facade element. This means that the sealing section has a height (DAH) along the direction perpendicular to the respective facade element. The amount of intumescent material can vary depending on the height. The height can depend on the application.In this way, different gap sizes can be closed as needed in the event of a fire based on the varying amount of intumescent material.
[0028] Optionally, a first width of the underside transverse to the longitudinal direction of the continuous fire protection strip is greater than a second width of the top side transverse to the longitudinal direction of the continuous fire protection strip. This means that the underside and the top side of the sealing section in this embodiment have different surface dimensions per unit length. This results in a trapezoidal cross-sectional area of the sealing section, in which the underside and the top side are oriented parallel to one another. The side surfaces connecting the underside and the top side, however, are beveled and oriented such that they do not form a right angle to at least one of the top sides and the underside (not an isosceles trapezoid). This geometry also makes the continuous fire protection strip usable for other applications, for example to line corresponding fire protection joints in wall or ceiling sections.The continuous fire protection strip can then be adapted to the respective joint geometry as required.
[0029] Preferably, transition sections extending along the longitudinal direction of the continuous fire protection strip between the underside and the top side of the sealing section are designed with chamfers and / or rounded edges and / or bevels. This avoids sharp edges between the transition sections and the underside or top side, thus reducing the risk of damage.
[0030] Optionally, a first bent edge extending in the longitudinal direction of the continuous fire protection strip is arranged between the sealing section and the fastening section. The bent edge defines the boundary between the sealing section and the fastening section. The bent edge allows, in use, only the sealing section to adjoin the base strip of the fire barrier along the direction perpendicular to the facade element. The fastening section, however, can be bent over so that it is oriented along this direction. This ultimately enables the sealing section to have a strip width that corresponds to the strip width of the base strip of the fire barrier.However, the fastening to the base strip is then carried out by coupling, for example by gluing, the fastening section of the continuous fire protection strip to the side surfaces of the base strip of the fire barrier (i.e. those surfaces that extend in the direction perpendicular to the facade element).
[0031] Preferably, the sealing section has at least one second bent edge extending in the longitudinal direction of the continuous fire protection strip between opposite lateral ends of the sealing section. The second bent edge is provided for the second fastening section and has the same function as the first bent edge.
[0032] Preferably, the sealing section of the endless fire protection strip can also have a carrier layer. The carrier layer can be oriented substantially parallel to a bottom and a top side of the sealing section, the surface normals of which are oriented substantially perpendicular to the respective facade element in use. The intumescent material can then be arranged on both sides of the carrier layer, between the carrier layer and the bottom side, and between the carrier layer and the top side of the sealing section. As a result, in the event of a fire, the endless fire protection strip expands in opposite directions from the carrier layer, which can be advantageous for some applications. For example, this is advantageous if the endless fire protection strip is fixed to the base strip in such a way that the sealing section is arranged at a distance from an end face of the base strip.
[0033] According to a further aspect, a fire barrier with a base strip is provided. The base strip at least partially comprises a thermally insulating material. The fire barrier further comprises an endless fire protection strip as described above. The base strip has an end face whose surface normal is oriented substantially along the direction perpendicular to the respective facade element. The endless fire protection strip is fixed to the base strip by means of the fastening section such that the sealing section is arranged flush with the end face of the base strip.
[0034] In this case, "aligned" means that the sealing section is aligned with the end face along the direction perpendicular to the respective facade element. In other words, the sealing section of the continuous fire protection strip is arranged between the end face of the base strip and the respective facade element along the direction perpendicular to the respective facade element.
[0035] The fire barrier thus constructed combines the advantages of individual insulation components and fire protection strips. The fire barrier can be adapted to the respective geometry as needed using the base strip, while still reliably sealing the remaining gap for rear ventilation in the event of a fire using the continuous fire protection strip. Advantageously, incorrect cutting of the base strip does not immediately render the costly fire protection component unusable. Optionally, the sealing section is arranged laterally spaced and flush with the end face of the base strip.
[0036] Alternatively, the sealing section can also be in direct contact with the end face of the base strip. The contact can be formed in a planar manner. This means that the underside of the sealing section can be adjacent to the end face of the base strip. A surface normal of the underside of the sealing section is then oriented perpendicular to the respective facade element.
[0037] Here, “besides” means that the distance extends essentially along the surface normal of the front surface.
[0038] In a particular embodiment, the continuous fire protection strip has two fastening sections on opposite sides of the sealing strip. The first fastening section and the second fastening section can then be fixed to opposite sides of the base strip. The opposite sides of the base strip, to which the fastening sections are fixed, can extend substantially in a direction perpendicular to the respective facade element. This improves the fixation of the continuous fire protection strip to the base strip.
[0039] Optionally, the end face of the base strip has a width (BSB) perpendicular to the longitudinal direction of the base strip. The width of the sealing section (DAB) perpendicular to the longitudinal direction of the continuous fire protection strip can then be equal to, smaller than, or larger than the width (BSB) of the base strip. Preferably, the width of the sealing section (DAB) is equal to or smaller than the width (BSB) of the base strip. This allows the dimensions of the base strip and the sealing section to be coordinated.
[0040] Typically, such fire barriers must be designed to last the lifetime of the façade, i.e., at least for many years. If the continuous fire protection strip is attached to the base strip using an adhesive, the adhesive may lose its adhesive strength over time due to temperature fluctuations and other external influences. Therefore, the continuous fire protection strip, and in particular the sealing section thereof, can preferably be designed to be coupled to the base strip by means of a clamping device in such a way that the positioning of the continuous fire protection strip relative to the base strip of the fire barrier is ensured.
[0041] Alternatively, the endless fire protection strip, and in particular the sealing section thereof, can also be coupled to the respective facade element by means of a spring device in such a way that the positioning of the endless fire protection strip relative to the base strip of the fire barrier is ensured.

[0043] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings.

[0050] Figure 1 shows a simplified schematic representation of an endless fire protection strip 10 according to one embodiment.
[0051] Coordinate system 12 illustrates the usual orientations of the continuous fire protection strip 10 in use with respect to the length L, which in this case lies in the plane of the drawing, the width B, and the height H. Coordinate system 12 is typically related to the facade element arranged opposite the continuous fire protection strip 10 in use, since a constant gap is generally to be achieved between the continuous fire protection strip 10 and the facade element. This means that the height H is essentially oriented along the surface normal with respect to the facade element.
[0052] The continuous fire protection strip 10 comprises a sealing section 14. The sealing section 14 comprises a bottom side 16 that extends along the width and length. The width of the sealing section 14 is designated DAB herein. The sealing section 14 also comprises an upper side 18 that is oriented parallel to the bottom side 16 and spaced apart from it. Due to the distance between the bottom side 16 and the top side 18, the sealing section 14 has a sealing section height DAH.
[0053] The bottom side 16 and the top side 18 are connected to each other by transition sections 20A, 20B. In the use situation, the transition sections 20A, 20B extend along the longitudinal direction of the continuous fire protection strip 10.
[0054] Due to the underside 16, the top side 18, and the transition sections 20A, 20B, the sealing section 14 has an internal volume 22 per unit length. An intumescent material 24 is arranged at least partially in the internal volume 22. Furthermore, an at least partially elastic sealing material 26 can be arranged in the internal volume 22. The sealing material 26 can also be compressible. In the present case, the sealing material 26 is also non-combustible. Alternatively, the sealing material can also be partially combustible. The flammability of the sealing material 26 is generally selected based on legal requirements.
[0055] In this case, the top side 18 has a shorter OSB width compared to the bottom side 16 and the corresponding bottom side width USB. This results in a trapezoidal cross-sectional area of the interior volume 22.
[0056] In the present case, the transition sections 20A, 20B have the same inclination relative to the underside 16. In other words, the angle enclosed with the underside 16 is the same for both transition sections 20A, 20B, so that according to this embodiment, the cross-sectional area of the interior volume 22 corresponds to an isosceles trapezoid. Optionally, however, the angles can also be different, resulting in a cross-sectional area corresponding to a non-isosceles trapezoid.
[0057] Here, the endless fire protection strip 10 is shown according to its manufacturing configuration. The fastening sections border laterally on the sealing section 14. In this case, they also extend along the width B. In this case, the fastening sections 28A, 28B border in particular on the underside 16 of the sealing section 14. Along the longitudinal direction of the endless fire protection strip 10, and therefore in the plane of the drawing, the endless fire protection strip 10 has a first folding edge 30A and a second folding edge 30B. The respective fastening sections 28A, 28B can be pivoted about the first and second folding edges 30A, 30B, so that they no longer need to extend along the width B. In the use situation, the fastening sections 28A, 28B can therefore be at least partially oriented along the height H.
[0058] Furthermore, the fastening sections 28A, 28B have a fastening means 32 on at least one surface, or an adhesive is present. Optionally, the underside 16 and / or the top side 18 and / or the transition sections 20A, 20B and / or the fastening sections 28A, 28B can be laminated with a film 34, at least on their outer surfaces. The film 34 can have a grid structure 36. This improves the strength and resistance of the sections extending along the longitudinal direction of the continuous fire protection strip 10, thus reducing the risk of damage during manufacture or installation.
[0059] Figure 2 shows a simplified schematic representation of a fire barrier 40 with an endless fire protection strip 10 according to one embodiment.
[0060] The fire barrier 40 comprises a base strip 42, which extends from a substructure 44 of the respective building along the height H toward the opposite facade element 46. The base strip 42 has a width BSB and a height BSH.
[0061] The height distance D2 between the substrate 44 and the facade element 46 is thereby at least partially bridged by the base strip 42 and its height BSH, so that a residual height distance D1 results.
[0062] The base strip 42 typically comprises an insulating material 48 intended for thermal building insulation.
[0063] Optionally, the insulation material 48 can be fire-retardant or non-combustible.
[0064] An end face 50 of the base strip 42 of the fire barrier 40 is arranged opposite the respective facade element 46. In this case, the end face 50 is oriented parallel to the facade element 46.
[0065] The continuous fire protection strip 10 is generally arranged between the base strip 42 of the fire barrier 40 and the respective facade element 46. In particular, the continuous fire protection strip 10 is arranged, with respect to its sealing section 14, flush with the end face 50 along the height direction H relative to the opposite facade element 46.
[0066] Due to the height DAH of the sealing section 14 of the continuous fire protection strip 10, the remaining height distance D1 between the base strip 42 and the respective facade element 46 is partially spanned by the sealing section 14. This results in a gap height SH along the height direction between the sealing section 14 and the facade element 46. The gap height SH serves to provide rear ventilation for the facade.
[0067] For special applications, it may also be necessary to have no gap for rear ventilation.
[0068] According to this embodiment, the sealing section 14, with its underside 16, directly adjoins the end face 50 of the base strip 42. The underside 16 is thus in direct contact with the end face 50. The fastening sections 28A, 28B are pivoted about the respective folded edges 30A, 30B so that they extend along the height direction H, and are coupled to side surfaces 52A, 52B of the base strip 42. The fastening means 32, in this case the adhesive, are used for coupling.
[0069] In the event of a fire, the intumescent material 24 expands, causing the sealing section 14 to expand toward the facade element 46. Ultimately, the gap height SH can be closed by the expanding intumescent material 24. This prevents the fire from spreading from one side of the base strip 42 to the opposite side of the base strip 42.
[0070] Because the continuous fire protection strip 10 is generally separate from the base strip 42 of the fire barrier 40, in complex façade geometries, the base strip 42 can first be adapted to the façade geometry and then the continuous fire protection strip 10 can be arranged on it. Should a misalignment of the base strip 42 occur, the separation of the continuous fire protection strip 10 from the base strip 42 ensures that only the relatively inexpensive base strip 42 needs to be replaced or adapted. This prevents the cost-intensive component of the continuous fire protection strip 10 from becoming unusable due to an incorrect height dimension (BSH) of the base strip 42.
[0071] According to this embodiment, the fire barrier 40 further comprises a spring device 54, by means of which the positioning of the continuous fire protection strip 10 relative to the base strip 42 is ensured. The spring device 54 extends at least partially through the sealing section 14 of the continuous fire protection strip 10 and has two spring arms 56, which support the spring device 54 on the opposite facade element 46. This ensures the positioning of the continuous fire protection strip 10 relative to the base strip 42 even in the event that the adhesive used according to this embodiment to attach the fastening sections 28A, 28B to the side surfaces 52A, 52B of the base strip 42 loses its adhesive strength over time.
[0072] Figure 3 shows a simplified schematic representation of a continuous fire protection strip 10 according to another embodiment. Only the differences from the previous embodiment will be discussed here.
[0073] According to this embodiment, the sealing section 14 of the continuous fire protection strip 10 now has two partial volumes 22A, 22B of the inner volume 22. The inner volume 22 is interrupted by a carrier layer 58. Starting from the carrier layer 58, the partial volumes 22A, 22B extend toward the bottom side 16 and the top side 18.
[0074] Optionally, the carrier layer 58 can also be laminated with a film 34. This ensures sufficient mechanical stability of the carrier layer 58.
[0075] The height DAH of the sealing section 14 then extends over the carrier layer 58.
[0076] Figure 4 shows a simplified schematic representation of a fire barrier 40 with a continuous fire protection strip 10 according to another embodiment. Only the differences from the previous embodiment will be discussed here.
[0077] The continuous fire protection strip 10 now has a sealing section 14 with two partial volumes 22A, 22B of the inner volume 22. The inner volume 22 is interrupted with respect to the partial volumes 22A, 22B by the carrier layer 58.
[0078] According to this embodiment, the fastening sections 28A, 28B have larger dimensions. By means of the fastening sections 28A, 28B, the endless fire protection strip 10 is coupled to the side surfaces 52A, 52B of the base strip 42. The fastening sections 28A, 28B are configured in this case in particular such that the endless fire protection strip 10 is arranged flush with the end surface 50 of the base strip 42 along the height direction H, but spaced apart from the end surface 50. In other words, a first gap height SH1 exists along the height direction H between the facade element 46 and the top side 18 of the sealing section 14, and a second gap height SH2 exists between the bottom side 16 of the sealing section 14 and the end surface 50 of the base strip 42.The first gap height SH1 and the second gap height SH2 result in the total gap dimension which is not spanned by the endless fire protection strip 10 with respect to the residual height distance D1 between the base strip 42 and the facade element 46.
[0079] For some applications, the rear ventilation provided along the height direction H on both sides of the continuous fire protection strip 10 may be advantageous.
[0080] Figure 5 shows a simplified schematic representation of a fire barrier 40 with a continuous fire protection strip 10 according to another embodiment. Only the differences from the previous embodiments will be discussed here.
[0081] For certain applications, it may be desirable for the continuous fire protection strip 10 to at least partially rest against the oppositely arranged facade element 46.
[0082] In the present case, the continuous fire protection strip 10 rests against the facade element 46 in the region of the bent edges 30A, 30B. The underside 16 of the sealing section 14 extends between the bent edges 30A, 30B. Unlike in the previous embodiments, this underside is arranged opposite the facade element 46 and thus not opposite the end face 50 of the base strip 42. In contrast to the previous embodiments, the top side of the sealing section 14 is opposite the end face 50 of the base strip 42.
[0083] In addition, the underside 16 has a kink 60 around which a first partial section 62A of the underside 16 is pivoted relative to a second partial section 62B of the underside 16.
[0084] Furthermore, the sealing section 14 is divided into two sub-regions 14A, 14B. Each sub-region 14A, 14B is assigned to a sub-section 62A, 62B of the underside 16 of the sealing section 14. The sub-sections 14A, 14B are spaced apart from one another by the kink 60.
[0085] Alternatively, the sealing section 14 can also extend beyond the kink point 60.
[0086] The kink 60 prevents the sealing section 24 from being in direct surface contact with the facade element 46, which could lead to a delay in the expansion of the intumescent material 24 in the event of a fire.
[0087] The present embodiment can do without an additional spring device 54. Instead, the spring action can be ensured by the fastening sections 28A, 28B, which can optionally be reinforced for this purpose. To counteract aging of the fastening means 32, the fastening sections 28A, 28B can optionally be additionally secured in the region of the side surfaces 52A, 52B of the base strip 42 by suitable devices, for example, clamping devices.
[0088] Figure 6 shows a simplified schematic representation of a continuous fire protection strip 10 according to another embodiment. Only the differences from the previous embodiments will be discussed here.
[0089] The sealing section 14, in turn, has an internal volume 22, which is delimited by the bottom side 16, the top side 18, and the transition sections 20A, 20B. In contrast to the previous embodiments, chamfers 64 are arranged between the top side 18 and the transition sections 20A, 20B to prevent sharp edges in the contour of the sealing section 14. This can reduce the risk of damage to the sealing section 14 during manufacturing or installation.
[0090] As an alternative to the chamfers 64, corresponding roundings can also be provided.
[0091] Furthermore, the chamfers 64 or fillets may also be provided in other areas, for example, at the transitions between the transition sections 20A, 20B and the underside 16 of the sealing section 14. Quantities and numbers may be referred to in the present disclosure. Unless expressly stated, such quantities and numbers are not to be considered limiting, but rather as examples of the possible quantities or numbers in connection with the present disclosure. In this context, the term "plurality" may also be used in the present disclosure to refer to a quantity or number. In this context, the term "plurality" means any number greater than one, e.g., two, three, four, five, etc. The terms "about," "approximately," "near," etc., mean plus or minus 5% of the stated value.
