Description

Forming rod and device for manufacturing package and package

Technical Field

Embodiments of the present disclosure relate to a shaped rod for use in manufacturing a package, an apparatus method including the shaped rod, and a package.

Background

One type of package includes an outer shell and a flow directing member. The housing may be, for example, cardboard, plastic, etc. The outer shell of the package is formed by overlapping two seam ends of the outer shell material with each other to form a closed polygonal material and then closing the two longitudinal ends. This type of package is particularly suitable for containing liquid food products such as orange juice, milk, yoghurt, soup and the like. One of the two longitudinal ends may be formed by folding and pressing into a shape in which the cross section gradually decreases in the longitudinal direction toward the free end (e.g., a truncated pyramid shape). In this way, the liquid content can easily flow out of the package. And the longitudinal end may also be closed by attachment to the flow guide member. For example, the flow directing member is made of a thermoplastic polymer material. For example, the flow directing member is pressed together with the housing by applying heat and pressure.

In such a package, the seam area is formed by the overlapping of the shell material with each other at the two seam ends. The shell has a variation in thickness at the seam region, and the variation in thickness may not be a smooth transition. Thus, when the baffle member and the housing are pressed together, there may be air-containing voids between the baffle member and the housing at the seam area, which would compromise the seal of the package, leading to the ingress and growth of bacteria and the like.

SUMMERY OF THE UTILITY MODEL

At least one embodiment of the present disclosure provides a shaped bar for manufacturing a package for cooperating with a mating assembly to press an outer shell of the package to a flow directing feature of the package. The profile rod includes a rod-shaped main body for housing the outer shell thereon and a mounting end portion connected to an end portion of the main body for mounting the deflector. The mounting end includes a plurality of contoured side walls against which the flange portion of the flow directing component is configured to press when pressed. At least one of the plurality of contoured side walls has an outwardly offset abutment surface having an abutment centerline parallel to an extension direction along which the body extends, and the contoured side wall has a wall centerline parallel to the extension direction that is offset from the corresponding wall centerline in a transverse direction perpendicular to the extension direction.

For example, in some embodiments, the abutment centerline of the abutment surface is offset from the corresponding wall centerline by a first distance in the range of 10-25% of the width of the corresponding profiled sidewall in the transverse direction.

For example, in some embodiments, the abutment centerline of the abutment surface is offset from the corresponding wall centerline by a first distance in the range of 2.8-7 mm.

For example, in some embodiments, the abutment surface is offset outwardly from the contoured sidewall parallel to the contoured sidewall by a second distance in the range of 0.4-0.6 mm.

For example, in some embodiments, the abutment surfaces are inclined outwardly from the profiled side wall by a first angle to be offset outwardly from the corresponding profiled side wall, the first angle being in the range 6 ° -20 °.

For example, in some embodiments, the width of the abutment surface in the transverse direction is in the range of 4-8 mm.

For example, in some embodiments, at least one of the profiled side walls has an outwardly projecting snap-in portion for securing the flow directing component to the mounting end, the snap-in portion having a projecting surface facing away from the profiled side wall, the projecting surface serving as an abutment surface.

For example, in some embodiments, the mounting end further comprises an end surface connected to a plurality of shaped sidewalls, the plurality of shaped sidewalls being four shaped sidewalls that enclose the end surface into a square, each shaped sidewall having a snap-in portion, the snap-in portions on the plurality of shaped sidewalls being axisymmetric with respect to a diagonal of the square.

For example, in some embodiments, at least one of the profiled side walls has an outwardly projecting snap-in portion for securing the flow directing component to the mounting end and an outwardly projecting abutment portion different from the snap-in portion, the abutment portion having an abutment surface.

For example, in some embodiments, the clamping portion has a clamping centerline parallel to the direction of extension, the clamping centerline coinciding with the wall centerline.

At least one embodiment of the present disclosure provides an apparatus for manufacturing a package, comprising a shaped rod as described above and a mating component. The mounting end of the shaped rod and the mating assembly are configured to sandwich the wrapped housing and the wrapped baffle member therebetween to press the housing to the baffle component.

For example, in some embodiments, a mating member of a mating component that mates with at least one contoured sidewall having an abutment surface includes a rigid portion and a resilient portion overlying the rigid portion, the resilient portion being more resilient than the rigid portion.

At least one embodiment of the present disclosure provides a package comprising an outer shell comprising an end region and a flow directing component comprising a flow directing nozzle and a flange portion comprising a plurality of flange sidewalls, at least one of the plurality of flange sidewalls having a protrusion located at a seam region of the outer shell and integral with the corresponding flange sidewall.

For example, in some embodiments, the flange sidewall has a flange centerline extending parallel to a central axis of the flange portion, and the tab extends parallel to and is offset from the flange centerline.

For example, in some embodiments, the housing includes a thermoplastic polymer layer, the flange portion includes a thermoplastic polymer portion, and the thermoplastic polymer layer of the housing and the thermoplastic polymer portion of the flange portion fuse and form the tab.

For example, in some embodiments, the housing includes a first seam end and a second seam end, the first seam end overlapping the second seam end at a seam region such that the first seam end is located inboard of the second seam end, the projection filling a transition region between a terminal end of the first seam end and the second seam end.

For example, in some embodiments, the shell comprises a shell material layer, and the first seam end is folded to form a folded portion having two shell material layers, the folded portion terminating at the first seam end.

For example, in some embodiments, a portion of the shell material layer of the folded portion is removed such that the thickness of the end of the folded portion is reduced.

At least one embodiment of the present disclosure provides a method of manufacturing a package, comprising: securing a wrapped deflector member to a mounting end of a forming rod, the deflector member including a deflector lip and a flange portion, the flange portion including a plurality of flange sidewalls; sleeving the wrapped outer shell on the rod-shaped body of the forming rod so that the end region of the outer shell is positioned around the flange part of the flow guide part; and positioning the end region and the flange portion between the mating component and the mounting end, pressing the mounting end with the mating component to press the end region of the housing to the flange portion of the flow guide member. The profiled rod is as described above. At the time of pressing, the abutment surface abuts at least a part of the seam region of the housing via the flange side wall, so that a projection is formed on the flange side wall of the flow guide member, the projection being located at a position where the flange side wall abuts the abutment surface.

Molded rods and mating assemblies are typically used to press the outer shell to the flow directing component. Fig. 1 illustrates a perspective view of a portion of a contoured rod 100 according to an embodiment of the present disclosure. Fig. 7 shows a perspective view of the housing 300, the air guide member 400, and the mounting end 120 of the shaped rod 100 shown in fig. 1, mounted on the shaped rod 100 after pressing the housing 300 to the air guide member 400. Fig. 17 illustrates a perspective view of a flow directing feature 400 of a package after pressing, and fig. 18 illustrates a perspective view of a mating assembly 200, according to an embodiment of the disclosure.

As shown in fig. 7, the housing 300 comprises an end region 310 and a seam region 320, the end region 310 being in the shape of a truncated pyramid with four housing side walls and having a quadrangular cross section tapering towards the ends. The housing 300 may be attached to the flow guide 400 by its end region 310.

As shown in fig. 17, the flow guide member 400 includes a flow guide nozzle 420 and a flange portion 410. The guide nozzle 420 is cylindrical, and the flange portion 410 is connected to one end of the guide nozzle 420 and protrudes radially outward. Similar to the end region 310, the flange portion 410 has a truncated pyramid shape with four flange sidewalls 411 and a quadrangular cross section gradually decreasing toward one side of the blast nozzle 420.

As shown in fig. 1, the profiled bar 100 includes a main body 110 and a mounting end 120 connected to an end of the main body 110. The body 110 may be an elongated rod shape extending in an extending direction and having a longitudinal axis. Similar to the end region 310 and the flange portion 410, the mounting end 120 has the shape of a truncated pyramid with four profiled side walls 121 and with a quadrangular cross section which decreases gradually in a direction away from the body 110.

It is to be noted that the end region 310, the flange portion 410 and the mounting end 120 are not limited to being of a truncated pyramid shape, for example, they may also be of a truncated cone shape, and the end region 310, the flange portion 410 and the mounting end 120 are not limited to having a quadrangular cross section, but may also have a cross section of a triangular, pentagonal, circular, elliptical or the like shape.

The plurality of shaped rods 100 may be mounted to a rotatable axle, wherein the plurality of shaped rods 100 are positioned such that their longitudinal axes intersect the rotational centerline of the axle and are parallel to the radial direction of the axle. By rotating the axles, the shaped rods 100 may be positioned to various stations to complete the attachment of the flow directing member 400 to the housing 300. At one station, the flow directing member 400 may be mounted to the mounting end 120. At another station, the housing 300 may be sleeved onto the body 110. For example, the housing 300 may be sleeved onto the body 110 such that the end region 310 of the housing 300 is located around the flange portion 410 of the flow guide member 400. At yet another station, heat may be applied to the flow directing features 400 and the housing 300. For example, the flow guide member 400 may be made of a thermoplastic polymer such as Polyethylene (PE). For example, the housing 300 may include cardboard or aluminum foil, and a thermoplastic polymer such as polyethylene is coated on a surface of the housing 300. By applying heat, the thermoplastic polymer of the flow guide 400 and the outer shell 300 may be melted (i.e., activated). At yet another station, mating assembly 200 applies pressure to flange portion 410 of flow guide 400 and end region 310 of outer housing 300, wherein flange portion 410 of flow guide 400 and end region 310 of outer housing 300 are sandwiched between mounting end 120 and mating assembly 200. As shown in fig. 18, mating assembly 200 includes four mating members 210, 220. The end region 310 of the outer shell 300 is first pressed by two opposing first counter members 210 of the four counter members 210, 220 to fold and partially press the end region 310 to the flow guide means 400 so that the flow guide means 400 is fused with the thermoplastic polymer of the outer shell 300, and the end region 310 of the outer shell 300 is then pressed by two opposing second counter members 220 of the other four counter members 210, 220 to fold and fully press the end region 310 to the flow guide means 400 so that the flow guide means 400 is fused with the thermoplastic polymer of the outer shell 300. As such, the molding rod 100 presses the outer shell 300 of the package to the guide member 400 by cooperating with the counterpart member 200.

The housing 300 has a variation in thickness at the seam region 320 and the variation in thickness may not be a smooth transition. Therefore, when the baffle member 400 and the housing 300 are pressed together, there may be air-containing voids between the baffle member 400 and the housing 300 at the seam area 320, which would compromise the sealability of the package, resulting in the ingress and growth of bacteria and the like.

The present disclosure relates to a profiled rod 100. To avoid the formation of a gap between the deflector member 400 and the housing 300, the mounting end 120 of the profiled rod 100 is provided with an abutment surface 1231 offset outwardly from the profiled sidewall 121. Due to the provision of the abutment surface 1231, when pressing the outer shell 300 of the package to the deflector 400, the flange side wall 411 of the flange portion 410 of the deflector 400 can be abutted with the abutment surface 1231 at the seam area 320 of the outer shell 300. At the time of pressing, at least the material of the flow guide member 400 will fill in between the end region 310 of the outer shell 300 and the flange side wall 411 of the flow guide member 400 at the seam region 320 of the outer shell 300 due to the crimping force from the abutment surface 1231 and the mating members 210, 220, thereby avoiding the formation of a gap between the end region 310 of the outer shell 300 and the flange side wall 411 of the flow guide member 400 due to the seam region 320 at the time of pressing. Therefore, it can be ensured that the housing 300 is reliably pressed to the flow guide member 400.

Fig. 2 shows a perspective view of the mounting end 120 of the shaped bar 100 shown in fig. 1, fig. 3 shows a plan view of the mounting end 120 of the shaped bar 100 shown in fig. 1, and fig. 4 shows a side view of a portion of the mounting end 120 of the shaped bar 100 shown in fig. 1.

As shown in fig. 1-4, in the present embodiment, the mounting end 120 includes four contoured sidewalls 121 and a quadrilateral end surface 124 connected to the contoured sidewalls 121. Each profiled sidewall 121 is inclined outwardly with respect to the extension direction along which the body 110 extends. Each of the molding side walls 121 has a snap-in portion 122 protruding outward for fixing the flow guide member 400 to the mounting end portion 120. The snap-in portion 122 has a protruding surface 1221 away from the profiled side wall 121. The molding side wall 121 has a wall surface center line 1211 parallel to the extending direction, which is located in the middle of two outermost points of the molding side wall 121 in a lateral direction perpendicular to the extending direction. The catching portion 122 has a catching center line parallel to the extending direction, which is located at the middle of two outermost points of the protruding surface 1221 in the lateral direction perpendicular to the extending direction. Here, the clamping center line coincides with the wall surface center line 1211. The protruding surface 1221 protrudes from the shaped sidewall 121 in an inclined manner such that an upper side of the protruding surface 1221 away from the body 110 is continuously connected with the shaped sidewall 121, and the protruding surface 1221 is inclined outward from the shaped sidewall 121 by a first angle θ. For example, the first angle θ is in the range of 6-20, such as 12.52.

Furthermore, one of the four molding side walls 121 has an outwardly projecting abutment 123 different from the snap-in portion 122, the abutment 123 having an outwardly facing abutment surface 1231. The abutment surface 1231 projects outwardly from the molding sidewall 121 parallel to the molding sidewall 121 by a second distance d2. For example, the second distance d2 is in the range of 0.4-0.6 mm. It should be noted that the abutment surfaces 1231 may be offset outwardly from the contoured sidewall 121 in any suitable manner, in a parallel manner or in an inclined manner.

The abutment surface 1231 has an abutment centerline 1232 parallel to the extending direction, which is located midway between the outermost two points of the abutment surface 1231 in the lateral direction perpendicular to the extending direction. Due to relevant standards regarding packaging, for example, it is desirable to position the seam area 320 of the outer shell 300 of the package offset from the centerline of the respective side wall of the outer shell. Therefore, in order to abut against the seam region 320, the abutment center line 1232 of the abutment surface 1231 is offset from the corresponding wall surface center line 1211 by the first distance d1 in the lateral direction. For example, the first distance d1 is in the range of 10-25%, such as 10% or 17.4%, etc., of the width of the corresponding shaped sidewall 121 in the transverse direction. For example, the first distance d1 is in the range of 2.8-7 mm.

Here, the surfaces of the molding side wall 121, the projecting surface 1221, and the abutment surface 1231 are substantially flat surfaces. It is noted that a substantially flat surface is meant to not exclude that the surface has slots and not to exclude that there are transition sections between the surface and the adjacent surface. For example, the outermost two points refer to the outermost two points of the flat extension of the respective surface, irrespective of the transition section.

The seam region 320 may span a width range in the transverse direction perpendicular to the direction of extension, and there may be an error in the relative position of the seam region 320 and the abutment surface 1231. Thus, to ensure that the seam region 320 can adequately abut the abutment surface 1231, the width of the abutment surface 1231 can be in the range of 4-8 mm.

In the present embodiment, the click portion 122 is provided separately from the abutment surface 1231, and the click portion 122 is located on the wall surface center line 1211 while the abutment surface 1231 is offset from the wall surface center line 1211. The unbalance of the pressing force caused by the deviation of the clamping portion 122 to one side is avoided, and the sealing performance between the housing 300 and the flow guide part 400 can be damaged by the unbalanced pressing force.

Fig. 5 shows a schematic view of the housing 300, the air guide member 400, and the mounting portion of the shaped rod 100 shown in fig. 1 mounted on the shaped rod 100 before pressing the housing 300 to the air guide member 400; fig. 6 shows a schematic view of the housing 300, the air guide member 400, and the mounting portion of the molding rod 100 shown in fig. 1, mounted on the molding rod 100 after pressing the housing 300 to the air guide member 400.

As shown in fig. 5 and 6, the outer shell 300 includes a first seam end 311 and a second seam end 312, the two seam ends 311, 312 overlapping each other at a seam area 320 such that the first seam end 311 is located inside the second seam end 312. The first seam end 311 of the shell 300 is folded to form a folded portion having two layers of shell material. Although in the present embodiment, a portion of the shell material layer of the folded portion is removed (e.g., by cutting or grinding) such that the thickness of the end of the folded portion (i.e., the end of the first seam end 311) is reduced, the shell 300 still has a greater thickness at the seam region 320 than elsewhere, and may not have a smooth transition. According to an embodiment of the present disclosure, the abutment 123 is provided at a position corresponding to the seam area 320 of the outer shell 300, such that when the outer shell 300 is pressed to the flow guiding member 400, the outer shell 300 abuts against the abutment surface 1231 of the abutment 123 at the seam area 320 (in particular at a transition area between the tip of the first seam end 311 and the second seam end 312), and the flow guiding member 400 is between the abutment surface 1231 and the outer shell 300. Accordingly, formation of a void containing air between the outer shell 300 and the flow guide member 400 is avoided, and the thermoplastic polymer materials of the outer shell 300 and the flow guide member 400 in a melted state flow into the void that may otherwise be formed due to the pressing of the abutment surface 1231 and the mating members 210, 220. As shown in fig. 6 and 17, a protrusion 412 is formed on a flange sidewall 411 of the flange portion 410 of the guide member 400. The projection 412 fills in the transition region between the end of the first joint end 311 and the second joint end 312. Note that the arrangement of the seam area 320 of the housing 300 of the present disclosure is not limited to such a configuration. For example, the first seam end 311 may not have a folded portion. For example, a portion of the folded portion of the first seam end 311 may not be removed.

For the sake of brevity, the same or similar parts as those of the embodiment described with reference to fig. 1 to 7 will be briefly described or omitted.

As shown in fig. 8-11, the mounting end 120 includes four contoured sidewalls 121 and a quadrilateral end surface 124 connected to the contoured sidewalls 121. Each profiled sidewall 121 is inclined outwardly with respect to the extension direction along which the body 110 extends. In contrast to the exemplary embodiment described with reference to fig. 1 to 7, the four profile side walls 121 are each provided with an outwardly projecting clip-on portion 122 for fixing the air guide element 400 to the mounting end 120, which clip-on portion has a projecting surface 1221 facing away from the profile side walls 121, which projecting surface 1221 serves as an abutment surface 1231.

In the present embodiment, the snaps 122 project outwardly from the contoured sidewall 121 in an inclined manner such that an upper side of the projecting surface 1221 (i.e., the abutment surface) remote from the main body 110 is continuously connected with the contoured sidewall 121 and the abutment surface 1231 is inclined outwardly from the contoured sidewall 121 by the first angle θ. For example, the first angle θ is in the range of 6-20 °, such as 12.52 °. Four profiled side walls 121 enclose the end surfaces 124 in a square shape. In order to apply a more uniform and balanced crimping force, the four snaps 122 on the contoured sidewall 121 are axisymmetric with respect to the diagonal of the square. Further, to ensure that the seam region 320 can adequately abut the abutment surface 1231, the width of the abutment surface 1231 may be in the range of 4-8 mm.

As shown in fig. 12 and 13, one snap-in portion 122 is provided at a position corresponding to the seam area 320 of the outer case 300, so that when the outer case 300 is pressed to the flow guide member 400, the outer case 300 abuts against one protruding surface 1221 of the snap-in portion 122 serving as an abutment surface at the seam area 320 (particularly at a transition area between the tip of the first seam end 311 and the second seam end 312), and the flow guide member 400 is between the protruding surface 1221 and the outer case 300. Accordingly, formation of a void containing air between the outer shell 300 and the flow guide member 400 is avoided, but the thermoplastic polymer material of the outer shell 300 and the flow guide member 400 in a melted state flows into the void that may otherwise be formed due to the pressing of the abutment surface 1231 and the mating members 210, 220. As shown in fig. 13 and 17, a protrusion 412 is formed on a flange sidewall 411 of the flange portion 410 of the guide member 400. The projection 412 fills in the transition region between the end of the first joint end 311 and the second joint end 312.

In the present embodiment, the projecting surface 1221 of the snap-in portion 122 is used as an abutment surface, and an abutment portion is not provided separately, which simplifies the structure of the mounting end portion.

It is to be noted that the number and positions of the abutting portions 123 and/or the snap portions 122 may be modified and varied as needed. FIG. 14 depicts a perspective view of the mounting end 120 of the profiled rod 100 according to another embodiment of the present disclosure; FIG. 15 depicts a perspective view of the mounting end 20 of the profiled rod 100 according to yet another embodiment of the present disclosure; fig. 16 depicts a perspective view of the mounting end 120 of the profiled rod 100 according to yet another embodiment of the present disclosure.

For the sake of brevity, the same or similar parts as those of the embodiments described with reference to fig. 1-7 and 8-13 will be briefly described or omitted.

As shown in fig. 14, the mounting end portion 120 according to this embodiment has four shaped sidewalls 121 and a square end surface 124 connected to the shaped sidewalls 121. In contrast to the exemplary embodiments described above, the four profiled side walls 121 are each provided with two outwardly projecting snap-in portions 122 for fixing the flow-guiding part 400 to the mounting end 120, which have a projecting surface 1221 facing away from the profiled side walls 121, which projecting surface 1221 serves as an abutment surface. The snaps 122 project outwardly from the profiled side wall 121 in an inclined manner such that an upper side of the projecting surface 1221 (i.e., the abutment surface) remote from the main body 110 is continuously connected with the profiled side wall 121 and the abutment surface 1231 is inclined outwardly from the profiled side wall 121. The clamping centerlines of the projecting surfaces 1221 are all offset the same distance from the corresponding wall centerline 1211.

As shown in fig. 15, the mounting end portion 120 according to this embodiment has four shaped sidewalls 121 and a quadrangular end surface 124 connected to the shaped sidewalls 121. In contrast to the above-described embodiment, two outwardly projecting snap-in parts 122 for fixing the air guide member 400 to the mounting end 120 are provided on each of the opposing pairs of profiled side walls 121 on the four profiled side walls 121, which have projecting surfaces 1221 facing away from the profiled side walls 121, which projecting surfaces 1221 serve as abutment surfaces; and each of the other pair of the shaped sidewalls 121 of the four shaped sidewalls 121 is provided with one of the snapping portions 122 protruding outward for fixing the flow guide member 400 to the mounting end 120, which has a protruding surface 1221 facing away from the shaped sidewall 121. The click center line (i.e., the click center line 1232) of the protruding surfaces 1221 of the two click portions 122 serving as abutment surfaces is offset from the corresponding wall surface center line 1211. The center line of the other engaging portion 122 coincides with the wall surface center line 1211.

As shown in fig. 16, the mounting end portion 120 according to this embodiment has four shaped sidewalls 121 and a quadrangular end surface 124 connected to the shaped sidewalls 121. Unlike the above-described embodiment, each of the four molding side walls 121 is provided with one click portion 122 and two abutting portions 123 on both sides of the click portion 122. The snaps 122 protrude outward from the molding side wall 121 in an inclined manner such that an upper side of the protruding surface 1221 away from the main body 110 is continuously connected with the molding side wall 121, and the protruding surface 1221 is inclined outward from the molding side wall 121. The abutment 123 projects outwardly from the forming sidewall 121 in a parallel manner such that the abutment surface 1231 is parallel with the forming sidewall 121. The engagement center line of the projecting surface 1221 of the engagement portion 122 coincides with the wall surface center line 1211 of the molding side wall 121, and the abutment surfaces 1231 of the two abutment portions 123 are offset from the wall surface center line 1211 by the same distance.

The present disclosure also relates to an apparatus for manufacturing a package comprising a shaped rod 100 and a mating assembly 200 as described above.

As shown in fig. 18, mating assembly 200 includes four mating members 210, 220. The counterpart member 210 for cooperating with the abutment surface 1231 of the molding rod 100 to press at the seam region 320 of the outer shell 300 and the counterpart member 210 opposite to the counterpart member 210 may be provided to have a rigid portion and an elastic portion having elasticity greater than that of the rigid portion, the elastic portion covering the rigid portion. For example, the rigid portion may comprise aluminum or an aluminum alloy. The resilient portion may comprise a silicone polymer. Due to the use of the elastic portion, the counterpart member 210 has a certain elasticity, which helps to compensate the shape of the housing 300 at the seam area 320, thereby avoiding the generation of voids.

It is noted that the shape, number and arrangement of the mating members 210, 220 may be modified and varied according to the shape, number and arrangement of the molding rods 100 to be mated therewith, and the present disclosure is not limited thereto.

The present disclosure also relates to a package. For example, the package may be manufactured using, for example, a molded rod 100 as described above or an apparatus for manufacturing packages as described above.

The flow guide member 400 includes a flow guide nozzle 420 and a flange portion 410. The flange portion 410 includes a plurality of flange side walls 411, at least one flange side wall 411 of the plurality of flange side walls 411 having a projection 412. The tabs 412 are located at the seam area 320 of the housing 300 and are integral with the corresponding flanged side wall 411.

Since the projections 412 are formed in the seam area 320 instead of the air-containing voids formed in the seam area 320, it is ensured that the housing 300 and the flow guide member 400 can be reliably pressed together. The flange side wall 411 has a flange centerline extending parallel to the central axis of the flange portion 410, and the projection 412 extends parallel to and is offset from the flange centerline. The housing 300 may include a thermoplastic polymer layer such as polyethylene, the flange portion 410 may include a thermoplastic polymer portion in the form of a coating, the thermoplastic polymer layer of the housing 300 and the thermoplastic polymer portion of the flange portion 410 fuse and form the protrusion 412.

The present disclosure also relates to a method of manufacturing a package. For example, the method may be performed using a shaped rod 100 as described above or an apparatus for manufacturing a package as described above. For example, a package as described above may be formed by this method.

The method of manufacturing a package comprises: securing the wrapped deflector member 400 to the mounting end 120 of the profiled rod 100; sleeving the packed housing 300 on the rod-shaped body 110 of the molding rod 100 such that the end region 310 of the housing 300 is located around the flange portion 410 of the guide member 400; and positioning the end region 310 and the flange portion 410 between the mating member 200 and the mounting end 120, pressing the mounting end 120 with the mating member 200 to press the end region 310 of the outer shell 300 to the flange portion 410 of the flow guide member 400. Upon pressing, the abutment surface 1231 abuts at least a portion of the seam area 320 of the housing 300 via the flange side wall 411 of the flange portion 410 of the flow guide member 400, so that a protrusion 412 is formed on the flange side wall 411 of the flow guide member 400, the protrusion 412 being located at a position where the flange side wall 411 abuts the abutment surface 1231.

The scope of the present disclosure is not defined by the above-described embodiments but is defined by the appended claims and equivalents thereof.
