DETAILED DESCRIPTION
The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.
One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details. Additionally, features depicted in the drawings with like shading, cross-hatching, and/or coloring can comprise shared compositions and/or materials.
Vacuum bags can be used to facilitate operation of various types of vacuum cleaners. For example, vacuum bags can be installed within the inner circumference of a collection container of the vacuum cleaner. During operation of the vacuum cleaner, the vacuum bags can collect debris, dirt, dust, and/or the like. Depending on the application of the vacuum cleaners, the vacuum bags may be expected to collect large amounts (e.g., hundreds of pounds) of debris. Additionally, some vacuum cleaners can utilize an inlet that protrudes into the vacuum bags to establish fluid communication between the cleaner and bag; thereby inhibiting removal of the bag without damaging the walls of the bag.
Various embodiments described herein regard vacuum bags that can exhibit enhanced strength and/or durability characteristics (e.g., as compared to existing vacuum bags) to accommodate a variety of vacuum cleaner applications. One or more embodiments described herein can include a vacuum bag with one or more SMS liners adjacent to one or more carrier layers comprised of a non-woven material (e.g., one or more paper layers). In various embodiments, the one or more SMS liners can be formed from an integral SMS material, where the meltblown material is integrated within, and/or between, the fibers of the spunbond material (e.g., rather than positioned as a respective layer between layers of spunbond material). The one or more SMS liners can provide the vacuum bag with strength and/or durability advantages. For example, a benchmark strength test for vacuum bags can include filling a hanging vacuum bag with 150 pounds of weight. The vacuum bag can pass the strength test by hanging for 30 minutes without breaking. Various embodiments described herein can regard vacuum bags that can hang with 275 pounds of weight for at least 8 hours without breaking. Further, the one or more carrier layers can provide filtration advantages. Moreover, the one or more SMS liners can be positioned on the one or more carrier layers such that seams of the one or more vacuum bags can be formed via one or more adhesive layers. Thereby, the one or more vacuum bags can be manufactured without the need for sonic welding techniques that are typically employed with SMS materials.
FIG. 1 illustrates a diagram of an example, non-limiting vacuum bag 100 with one or more inlets 102 positioned on a front side 104 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In various embodiments, the one or more inlets 102 can enable one or more vacuum cleaners to establish a fluid communication with the interior of the one or more vacuum bags 100. While FIG. 1 depicts the one or more inlets 102 with a circular shape, the architecture of the one or more inlets 102 is not so limited. For example, inlets 102 having a polygonal shape are also envisaged.
Further, the vacuum bag 100 can comprise one or more carrier layers 106 and/or one or more SMS liner layers 108. In various embodiments, the one or more inlets 102 can be one or more holes formed in a portion of the one or more carrier layers 106 and/or SMS liner layers 108 comprising the front side 104 of the vacuum bag 100. For instance, FIG. 1 depicts the one or more inlets 102 as a hole formed in a portion of the one or more carrier layers 106 and/or SMS liner layers 108, whereupon the portion of the SMS liner layers 108 positioned within the interior of the vacuum bag 100 is visible. Additionally, the one or more inlets 102 can be at least partially surrounded by one or more collars 110. For instance, the one or more collars 110 can comprise a rigid material (e.g., cardboard, plastic, ceramic, metal, resign, a combination thereof, and/or the like) to provide structural support to portions of the one or more carrier layers 106 and/or SMS liner layers 108 surrounding the one or more inlets 102.
FIG. 1 depicts the vacuum bag 100 in a collapsed state. During operation, an airflow entering the vacuum bag 100 via the one or more inlets 102 can expand the vacuum bag 100 to a greater volume. The volume capacity of the vacuum bag 100 can vary depending on application. For instance, the vacuum bag 100 can have a volume capacity of up to, for example, 25 gallons. While FIG. 1 depicts the vacuum bag 100 with a rectangular shape, the architecture of the vacuum bag 100 is not so limited. For example, additional shapes (e.g. circular or polygonal) can be employed based on one or more dimensions of the types of vacuum cleaner that will employ the vacuum bag 100. As shown in FIG. 1, the “Y” axis can depict a longitudinal direction of the vacuum bag 100, and the “X” axis can depict a lateral direction of the vacuum bag 100. In various embodiments, the vacuum bag 100 can have a width along the longitudinal direction ranging from, for example, greater than or equal to 2 inches and less than or equal to 72 inches (e.g., 58.5 inches). Additionally, the vacuum bag 100 can have a length along the lateral direction ranging from, for example, greater than or equal to 2 inches and less than or equal to 72 inches (e.g., 46 inches).
FIG. 2 illustrates a diagram of an example, non-limiting vacuum bag 100 with one or more seams positioned on a back side 202 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In various embodiments, the back side 202 of the vacuum bag 100 can comprise one or more longitudinal seams 204 and/or lateral seams 206. While FIG. 2 depicts the one or more longitudinal seams 204 and/or lateral seams 206 on the back side 202 of the vacuum bag 100, the architecture of the vacuum bag 100 is not so limited. For example, embodiments in which the front side 104 of vacuum bag 100 comprises the one or more longitudinal seams 204 and/or lateral seams 206 are also envisaged. For example, the one or more longitudinal seams 204 can extend along the longitudinal direction (e.g., “Y” axis shown in FIG. 2) of the vacuum bag 100 from a first end (e.g., a top end) to a second end (e.g., a bottom end). Also, the one or more lateral seams 206 can extend along the lateral direction (e.g., “X” axis shown in FIG. 2) of the vacuum bag 100 from third end (e.g., a left end) to a fourth end (e.g., a right end).
As show in FIG. 2, the one or more position of the one or more longitudinal seams 204 and/or lateral seams 206 are delineated with dotted lines. In various embodiments, the one or more longitudinal seams 204 and/or lateral seams 206 can be formed by folding and gluing portions of the carrier layer 106. Further, portions of the one or more longitudinal seams 204 and/or lateral seams 206 can overlap each other. The one or more longitudinal seams 204 can have a width (e.g., along the “X” axis shown in FIG. 2) ranging from, for example, greater than or equal to 2 centimeters and less than or equal to 1 foot. Additionally, the one or more lateral seams 206 can have width (e.g., long the “Y” axis shown in FIG. 2) ranging from, for example, greater than or equal to 2 centimeters and less than or equal to 1 foot. FIG. 2 depicts the vacuum bag 100 comprising a single longitudinal seam 204; however, embodiments in which the vacuum bag 100 comprises multiple longitudinal seams 204 are also envisaged. In various embodiments, the vacuum bag 100 can comprise a lateral seam 206 at the top and bottom ends of the vacuum bag 100 (e.g., as shown in FIG. 2).
FIG. 3 illustrates a diagram of an example, non-limiting exploded cross-sectional view of the vacuum bag 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. As shown in FIG. 3, the “Z” axis can depict a thickness direction of the vacuum bag 100. During operation, airflow between the front side 104 and the back side 202 of the vacuum bag 100 can cause the vacuum bag 100 to expand along the thickness direction.
In various embodiments, the walls of the vacuum bag 100 (e.g. the front side 104, the back side 202 and/or one or more intermediary sides connecting the front side 104 and/or the back side 202) can comprise the carrier layer 106, the one or more SMS liner layers 108, and/or one or more adhesive layers 302. In various embodiments, the one or more carrier layers 106 can be comprised of one or more non-woven materials. Example materials comprised in the one or more carrier layers 106 can include, but are not limited to: paper, wood paper, hemp paper, filter paper, a non-woven material comprising cellulose fibers, a combination thereof, and/or the like. For example, the one or more carrier layers 106 can comprise paper having a weight ranging from, for example, greater than or equal to 25 grams per square meter (g/m2) and less than or equal to 60 g/m2 (e.g., less than 50 g/m2).
In various embodiments, the one or more SMS liner layers 108 can comprise a SMS material having spunbond and meltblown polymer (e.g., polypropylene). For instance, the SMS material can have a structure in which the spunbond polymer and the meltblown polymer are integrated together to form a single layer of SMS material. Rather than a composition of a respective meltblown layer between respective spunbond layers, the SMS material comprised within the one or more SMS liner layers 108 can include meltblown polymer positioned between spunbond polymer fibers within the same layer of SMS material. In other words, the one or more SMS liner layers 108 can comprise a single layer of meltblown polymer integrated between fibers of spunbond polymer. In various embodiments, the one or more SMS liner layers 108 can have a weight ranging from, for example, greater than or equal to 20 g/m2 and less than 40 g/m2 (e.g., 30-40 g/m2).
In various embodiments, the one or more adhesive layers 302 can be positioned between the one or more carrier layers 106 and SMS liner layers 108. For example, the one or more adhesive layers 302 can adhere the one or more SMS liner layers 108 to the one or more carrier layers 106. Example types of adhesives that can comprised in the one or more adhesive layers 302 can include, but are not limited to: a hotmelt adhesive, a cold glue adhesive, a dry-bond adhesive, a thermoplastic polymer adhesive, a combination thereof, and/or the like.
FIG. 4 illustrates a diagram of an example, non-limiting cross-sectional view of the vacuum bag 100 along a plane that includes the one or more inlets 102 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. As shown in FIG. 4, the one or more inlets 102 can extend through one or more portions of the one or more carrier layers 106 and/or SMS liner layers 108 that define the front side 104 of the vacuum bag 100. Further, portions of the one or more carrier layers 106 can overlap each other (e.g., at the back side 202) to form the one or more longitudinal seams 204.
In various embodiments, the one or more adhesive layers 302 can be employed to adhere the one or more collars 110 to the one or more carrier layers 106 (e.g., on the front side 104 of the vacuum bag 100) adjacent to the one or more inlets 102. For example, the one or more adhesive layers 302 can be positioned between the one or more collar 110 and the one or more carrier layers 106 (e.g., as shown in FIG. 4). Thus, in various embodiments, the one or more adhesive layers 302 can adhere: the one or more collars 110 to the one or more carrier layers 106, the one or more SMS liner layers 108 to the one or more carrier layers 106, and/or respective portions of the one or more carrier layers 106 to each other to form the one or more longitudinal seams 204.
In one or more embodiments, the vacuum bag 100 can be manufacturing from a sheet of the one or more carrier layers 106 with the one or more SMS liner layers 108 adhered thereto. To form the structure of the vacuum bag 100, the sheet can be wrapped to a defined shape, where a portion of the carrier layer 106 located at one end can overlap another portion of the carrier layer 106 located at the opposite end. For example, one or more adhesive layers 302 can be positioned on the carrier layer 106 without being covered by the one or more SMS liner layers 108, thereby facilitating adhesion between the portions of carrier layer 106 overlapping each other at the longitudinal seam 204. As such, the one or more longitudinal seams 204 can comprise a first portion of carrier layer 106 overlapping a second portion of carrier layer 106, with one or more adhesive layers 302 adhering the first and second portions together (e.g., as shown in FIG. 4). At least because the one or more SMS liner layers 108 are not located between the overlapping portions of carrier layer 106, the longitudinal seam 204 can be formed via adhesion established by the one or more adhesive layers 302 directly in contact with the overlapping portions of carrier layer 106.
For example, the longitudinal seam 204 exemplified in FIG. 4 can be formed from a sheet 500 of carrier layer 106 having one or more adhesive layers 302 and SMS liner layers 108 in accordance with the positioning shown in FIG. 5. As shown in FIG. 5, the one or more carrier layers 106 can be covered by the one or more adhesive layers 302. Further, the one or more SMS liner layers 108 can be adhered to the one or more carrier layers 106 (e.g., via the one or more adhesive layers 302).
In one or more embodiments, the one or more SMS liner layers 108 can be absent from one or more margins (e.g., having a width ranging from, for example, 0.25 inches to 12 inches) of the sheet 500. For instance, the exemplary sheet 500 shown in FIG. 5 includes one or more SMS liner layers 108 absent from at least a side margin (e.g., left margin) adjacent to a first end 500a (e.g., left end) of the sheet 500. During manufacturing of the vacuum bag 100, the first end 500a of the sheet 500 can be bent and/or folded along the first rotation direction “R1”. Likewise, the second end 500b (e.g., right end) of the sheet 500 can be bent and/or folded along the second rotation direction “R2”. Thereby, the first and second ends 500a, 500b (left and/or right ends) of the sheet 500 can be bent and/or folded towards each other until the first edge 108a (e.g., left edge) of the SMS liner layer 108 and the second edge 108b (e.g., right edge) of the SMS liner layer 108 meet each other, whereupon the portion of carrier layer 106 comprising the left margin can overlap the second end 500b (e.g., right end) of the sheet 500. Further, the overlapped portion of carrier layer 106 can be pressed onto the underlying portion of carrier layer 106 to facilitate adhesion between the two portions (e.g., via the one or more adhesive layers 302) and establish the structure shown in FIG. 4.
FIG. 6 illustrates another diagram of an example, non-limiting cross-sectional view of the vacuum bag 100 along a plane that includes the one or more inlets 102 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. For example, FIG. 6 depicts another example structure that can be embodied by the one or more longitudinal seams 204. In one or more embodiments, portions of the one or more carrier layers 106 can be bent and pressed together to form the longitudinal seam 204 structure shown in FIG. 6.
As described herein, the vacuum bag 100 can be manufacturing from a sheet 500 of the one or more carrier layers 106 with the one or more SMS liner layers 108 adhered thereto. As shown in FIG. 7, in one or more embodiments, the one or more SMS liner layers 108 can further be absent from a right margin adjacent to the second end 500b (e.g., right end) of the sheet 500. The first and/or second ends 500a, 500b (e.g., left and/or right ends) of the sheet 500 can be bent and/or folded towards each other along the first rotation direction R1 and the second rotation direction R2. Further, portions of the carrier layer 106 comprising the side margins (e.g., left and right margins) can be bent to enable the first edge 108a (e.g., left edge) and the second edge 108b (e.g., right edge) of the one or more SMS liner layers 108 to meet. Once the first edge 108a (e.g., left edge) and the second edge 108b (e.g., right edge) of the one or more SMS liner layers 108 meet, the left and right margins of the sheet 500 can be pressed together to facilitate an adhesion (e.g., via the one or more adhesive layers 302) that can establish the longitudinal seam 204 structure shown in FIG. 6.
FIG. 8 illustrates another diagram of an example, non-limiting cross-sectional view of the vacuum bag 100 along a plane that includes the one or more inlets 102 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. For example, FIG. 8 depicts a third example structure that can be embodied by the one or more longitudinal seams 204. In the third example longitudinal seam 204 structure, the bent portions of carrier layer 106 shown in FIG. 6 can be further folded onto the surface of the surrounding carrier layer 106 (e.g., folded onto the back side 202 of the vacuum bag 100). As shown in FIG. 8, the one or more adhesive layers 302 can be further positioned on one or more sides of the bent portions of carrier layer 106 such that folding the bent portions can further adhere the bent portions to the surround surface of carrier layer 106.
FIG. 9 illustrates a diagram of an example, non-limiting cross-sectional view of the vacuum bag 100 comprising a one or more lateral seams 206 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In one or more embodiments, the vacuum bag 100 can comprise a plurality of lateral seams 206 (e.g., a top lateral seam 206 and/or a bottom lateral seam 206). As shown in FIG. 9, the one or more lateral seams 206 can comprise respective portions of the one or more carrier layers 106 adhered together via the one or more adhesive layers 302.
As described herein, the vacuum bag 100 can be formed from a sheet 500 of one or more carrier layers 106, adhesive layers 302, and/or SMS liner layers 108. As shown in FIGS. 5 and/or 7, the sheet 500 can include a top margin and a bottom margin, which can lack SMS liner layers 108. As the first end 500a (e.g., left end) of the sheet is bent/folded in the first rotation direction R1 and the second end 500b (e.g., right end) of the sheet is bent/folded in the second rotation direction R2, the top and/or bottom margins of the sheet 500 can be folded onto themselves. As shown in FIG. 9, overlapping the top margin upon itself can form a top lateral seam 206, and overlapping the bottom margin upon itself can form a bottom lateral seam 206. Thereby, a lateral seam 206 structure can be formed in which a portion of the carrier layer 106 constituting the front side 104 of the vacuum bag 100 can be directly adhered to (e.g., via the one or more adhesive layers 302) another portion of the carrier layer 106 constituting the back side 202 of the vacuum bag 100. At least because the one or more SMS liner layers 108 can be absent from the top and/or bottom margins of the sheet 500, the one or more lateral seams 206 can comprise a direct adhesion of respective portions of the one or more carrier layers 106, which can be facilitated by the one or more adhesive layers 302 without the need for welding techniques (e.g., sonic welding).
FIG. 10 illustrates a diagram of an example, non-limiting cross-sectional view of the vacuum bag 100 comprising a one or more lateral seams 206 with an additional example structure in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In various embodiments, the lateral seam 206 structure depicted in FIG. 9 can be further modified to achieve the example lateral seam 206 structure shown in FIG. 10. For example, the adhered portions of the one or more carrier layers 106 can be folded onto a side (e.g., back side 202) of the vacuum bag 100. Further, one or more adhesive layers 302 can be applied to the surface of the adhered portions of the one or more carrier layers 106 such that folding the adhered portions onto the side (e.g., back side 202) of the vacuum bag 100 can further adhere the portions to the side (e.g., back side 202) of the vacuum bag 100. For instance, the lateral seam 206 structure shown in FIG. 9 can be formed, one or more adhesive layers 302 can be applied to the back side 202 of the vacuum bag 100 adjacent to the overlapped top and/or bottom margins, and/or the overlapped top and/or bottom margins can be folded onto the back side 202 of the vacuum bag 100 to form the one or more lateral seam 206 structures shown in FIG. 10.
FIG. 11 illustrates a flow diagram of an example, non-limiting method 1100 that can facilitate manufacturing one or more longitudinal seams 204 of the vacuum bags 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity.
At 1102, the method 1100 can comprise providing one or more sheets of carrier layer 106 (e.g., comprising paper). In one or more embodiments, the one or more sheets can be provided with predefined dimensions. In some embodiments, the one or more sheets can be provided from one or more rolls of the carrier layer 106 and cut at defined intervals through the manufacturing of the vacuum bags 100.
At 1104, the method 1100 can comprise depositing one or more adhesive layers 302 onto the carrier layer 106. For example, the one or more adhesive layers 302 can be provided onto a surface of the sheet of carrier layer 106 that will define an interior circumference of the vacuum bag 100. In various embodiments, the one or more adhesive layers 302 can be deposited continuous across the sheet of carrier layer 106. In some embodiments, the one or more adhesive layers 302 can be deposited in accordance with one or more patterns onto the sheet of carrier layer 106. For instance, the one or more adhesive layers 302 can be deposited in a series of rows and/or columns across the sheet of carrier layer 106. Additionally, in one or more embodiments, the one or more adhesive layers 302 can be deposited onto the sheet of carrier layer 106 up to the edges of the sheet.
At 1106, the method 1100 can comprise depositing one or more SMS liner layers 108 onto the one or more adhesive layers 302 and absent a top, bottom, and/or side margin of the sheet of carrier layer 106. For example, the one or more SMS liner layers 108 can be deposited onto the one or more adhesive layers 302 in accordance with FIGS. 5 and/or 7. In various embodiments, the depositing the one or more SMS liner layers 108 can form the sheet 500 exemplified in FIGS. 5 and/or 7. For instance, the top, bottom, and/or side margin of the sheet 500 can comprise carrier layer 106 and adhesive layer 302 absent SMS liner layer 108. In one or more embodiments, the one or more SMS liner layers 108 can further be absent from both side margins of the sheet 500, as shown in FIG. 7. In various embodiments, the one or more SMS liner layers 108 can be fed from one or more rolls of SMS material, where the SMS material feed can be cut at defined lengths to facilitate the depositing at 1106.
At 1108, the method 1100 can comprise forcing a first side 500a and/or a second end 500b of the sheet 500 towards a center of the sheet 500 until a first edge 108a of the one or more SMS liner layers 108 meets a second edge 108b of the one or more SMS liner layers 108. For example, the first end 500a and/or second end 500b of the sheet 500 can be bent and/or folded along rotation direction R1 and/or R2 to facilitate the forcing at 1108. In various embodiments, the forcing at 1108 can form the sheet 500 manufactured at 1102-1106 into a tube shape. For instance, the sheet 500 can be wrapped around a mold to facilitate the forcing at 1108.
At 1110, the method 1100 can comprise overlapping the side margin of the sheet 500 onto the one or more carrier layers 106 located at the second end 500b of the sheet 500. For example, the sheet 500 can have a structure exemplified in FIG. 5, where the left side margin located at the first side 500a of the sheet 500 can overlap the second end 500b of the sheet 500 as a result of the forcing at 1108. At 1112, the method 1100 can comprise pressing the side margin of the sheet 500 and the underlying carrier layer 106 together to form one or more longitudinal seams 204. For example, the portion of adhesive layer 302 located in the side margin of the sheet 500 can be positioned between the overlapping carrier layer 106 portion and underlying carrier layer 106 portion as a result of the forcing at 1108 and the overlapping at 1110. Thus, the pressing at 1112 can force the overlapping portion of carrier layer 106 and underlying portion of carrier layer 106 into direct contact with the adhesive layer 302; thereby, adhering the carrier layer 106 portions together. For example, the forcing at 1108, overlapping at 1110, and pressing at 1112 can achieve the longitudinal seam 204 structure exemplified in FIG. 5. In various embodiments, manufacturing of the vacuum bag 100 can proceed with method 1200 to form the one or more inlets 102.
FIG. 12 illustrates a flow diagram of an example, non-limiting method 1200 that can facilitate manufacturing one or more inlets 102 of the vacuum bags 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In various embodiments, method 1200 can be performed prior to formation of the longitudinal seam 204 in method 1100 (e.g., prior to steps 1108-1112), concurrently with one or more steps of method 1100 (e.g., concurrently with steps 1108-1112), or subsequent to method 1100.
At 1202, the method 1200 can comprise cutting one or more inlets 102 into a surface of the one or more carrier layers 106. For example, the cutting at 1202 can extend through a carrier layer 106, an adhesive layer 302, and a SMS liner layer 108. In various embodiments, a die and punch can be employed to cut the one or more inlets 102 at 1202. In one or more embodiments, forming the longitudinal seam 204 via method 1100 can form a front side 104 and back side 202 of the vacuum bag 100. For example, the surface of the carrier layer 106 comprising the one or more longitudinal seams 204 can be the back side 202 of the vacuum bag 100 and the opposite surface of the carrier layer 106 can be the front side 104 of the vacuum bag 100. In one or more embodiments, the cutting at 1202 can be performed into the front side 104 of the vacuum bag 100.
At 1204, the method 1200 can comprise depositing one or more adhesive layers 302 onto one or more collars 110. As shown in FIGS. 1, 4, 6, and/or 8, the one or more collars 110 can have a hole complementary to the one or more inlets 102. The one or more adhesive layers 302 can be deposited onto the one or more collars 110 adjacent to the complementary hole. At 1206, the method 1200 can comprise positioning the one or more collars 110 adjacent to the one or more inlets 102 such that the one or more adhesive layers 302 on the one or more collars 110 face the carrier layer 106. In various embodiments, the one or more collars 110 can be fed from a stack of collars 110 and positioned adjacent to the one or more inlets 102 via a conveyor system. At 1208, the method 1200 can comprise pressing the one or more collars 110 onto the carrier layer 106. For example, the pressing at 1208 can adhere the one or more collars 110 to the carrier layer 106 via the one or more adhesive layers 302 such that the one or more collars 110 at least partially surround the one or more inlets 102.
FIG. 13 illustrates a flow diagram of an example, non-limiting method 1300 that can facilitate manufacturing one or more lateral seams 206 of the vacuum bags 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for the sake of brevity. In various embodiments, method 1200 can be performed subsequent to and/or concurrently with method 1100. Also, method 1300 can be performed prior to, subsequent to, or concurrently with method 1200.
At 1302, the method 1300 can comprise pressing together overlapping portions of the top margin of the sheet 500 to form a top lateral seam 206. For example, the forcing at 1108 can cause the top margin of the sheet 500 to overlap itself. For instance, forcing the sides of the sheet 500 in the first rotation direction R1 and/or second rotation direction R2 can result in the top margin overlapping itself across the width of the vacuum bag 100. At 1304, the method 1300 can comprise pressing together overlapping portions of the bottom margin of the sheet 500 to form a bottom lateral seam 206. For example, the forcing at 1108 can cause the bottom margin of the sheet 500 to overlap itself. For instance, forcing the sides of the sheet 500 in the first rotation direction R1 and/or second rotation direction R2 can result in the bottom margin overlapping itself across the width of the vacuum bag 100. In various embodiments, the pressing at 1302 and 1304 can be performed concurrently, simultaneously, or subsequently. In one or more embodiments, the pressing at 1302 and 1304 can result in the lateral seam 206 structure exemplified in FIG. 9.
At 1306, the method 1300 can comprise depositing one or more adhesive layers 302 onto the carrier layer 106 adjacent to the top and bottom lateral seams 206 formed at 1302 and 1304. For example, the one or more adhesive layers 302 can be deposited on portions of the back side 202 of the vacuum bag 100 adject to the lateral seams 206. At 1308, the method 1300 can comprise folding the top and/or bottom lateral seams 206 onto the adjacent adhesive layers 302 (e.g., deposited at 1306) to adhere the top and/or bottom lateral seams 206 to the surface of the carrier layer 106 (e.g., back side 202 of the vacuum bag 100). In various embodiments, the folding at 1308 can result in the lateral seam 206 structure exemplified in FIG. 10.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. As used herein, the terms “example” and/or “exemplary” are utilized to mean serving as an example, instance, or illustration. For the avoidance of doubt, the subject matter disclosed herein is not limited by such examples. In addition, any aspect or design described herein as an “example” and/or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs, nor is it meant to preclude equivalent exemplary structures and techniques known to those of ordinary skill in the art.
