Abstract
Description
MACHINE-OPENABLE PAPER MAILERS AND ASSOCIATED MACHINESSPECIFICATIONBACKGROUND
[0001] The present disclosure is in the technical field of paper mailers and machines for handling paper mailers. More particularly, the present disclosure is directed to paper mailers that can be reliably opened by an automated machine and to automated machines for opening such paper mailers.
[0002] A wide variety of products — including documents, books, consumer products, fragile items, and other items — are transported in various t pes of cushioned mailing envelopes generally called ‘"mailers”.
[0003] One type of a commercial mailer is an envelope with a front and rear wall, sealed at its two lateral and bottom edges, with a flap integrally formed from and extending from the rear wall. The flap extends beyond the upper end of the front wall when the envelope is open. The flap includes on one side a pressure sensitive adhesive that is covered by a release tape. After the envelope is filled with an article to be mailed, the release tape is removed from the flap, and the flap is folded over and adhered to the exterior surface of the front wall, thus sealing the envelope.
[0004] The walls of this type of commercial envelope comprise a multilayer outer ply, and an air cellular material forming an inner ply. The air cellular material is typically a material such as BUBBLE WRAP™ air cellular material sold by Sealed Air Corporation. Over many years, all-plastic mailers became more popular. These all plastic mailers typically have an outer ply that comprises an outer layer of a high density polyethylene (HDPE). and an inner layer comprising a low density' polyethylene (LDPE). The outer layer thus forms the outermost layer of the envelope. The inner layer is in adhering contact with the air cellular material of the inner ply.
[0005] However, all-plastic mailers nevertheless have some disadvantages. In particular, all-plastic are typically very difficult for consumers to recycle. All-plastic mailers typically include types of films that are not accepted in the most convenient recycling locations. In particular, all-plastic mailers are not accepted in most curbside recycling bins. It may be possible for consumers find drop-off recycling locations that will accept all-plastic mailers. However, it is typically inconvenient for consumers to take used all-plastic mailers to such drop-off recycling locations and many all-plastic mailers end up being thrown away and ending up in landfill or other solid waste disposal facilities (e.g., landfills).SUMMARY

[0036] The present disclosure describes embodiments of mailers formed from a web. The web is arranged to form two panels. The panels are bordered by two sides, a bottom, and a top of the mailer. The web includes a paper skin layer and a paper cushioning layer. The paper skin layer is on an outer side of each of the two panels and the paper cushioning layer is on an inner side of each of the two panels. The paper skin layer of one panel extends a first distance from the bottom and the paper skin layer of the other panel extends a second distance from the bottom. The first distance is greater than the second distance such that an offset exists between the tops of the paper skin layers of the two panels. The embodiment of mailers with offset tops disclosed herein can be opened reliably by a machine that blows a stream of gas at the top to cause the offset top to open.
[0037] Figs. 1A and IB depict front and cross-sectional views, respectively, of an embodiment of a mailer 100. The mailer 100 is formed from a w eb that includes a paper skin layer 102 and a paper cushioning layer 104. In some embodiments, the paper skin layer 102 is formed from kraft paper, such as 50# kraft paper. In some embodiments, the paper skin layer 102 can be uncoated paper. In some embodiments, the paper skin layer 102 can be paper coated — either fully coated or partially coated — in a polymer to enable the paper skin layer 102 to be connected to the paper cushioning layer 104 and / or to itself. In some embodiments, it may be desirable to minimize the amount of any coating on the paper of the paper skin layer 102 so that the mailer 100 is recyclable and / or repulpable.
[0038] The paper cushioning layer 104 is a paper layer having a nonplanar form. In some embodiments, the paper cushioning layer 104 is formed into a nonplanar layer by pressing orembossing the paper of the paper cushioning layer 104. In some embodiments, the paper of the paper cushioning layer is an extensible paper having a stretch to failure of at least 4% in any direction. In the depicted embodiment, the paper cushioning layer 104 has embossed protrusions in the form of hemispheres (or “bubbles”). In other embodiment, the paper cushioning layer 104 can have any shape of protrusions or any other pattern or design that causes the paper cushioning layer 104 to be nonplanar. Other examples of paper cushioning layers are shown in International Application No. PCT / US2023 / 013616, in U.S. Patent Application No. 63 / 533,927, and in U.S. Patent Application No. 63 / 536,732, the contents of each of which are hereby incorporated by reference in their entirety.
[0039] The web can be formed by connecting the paper skin layer 102 to the paper cushioning layer 104. In some embodiments, one or both of the paper skin layer 102 and the paper cushioning layer 104 is coated with a polymer that can be heated to cause the polymer coating to bond the paper skin layer 102 to the paper cushioning layer 104. In other embodiments, an adhesive is applied to one or both of the paper skin layer 102 and the paper cushioning layer 104 and then the paper skin layer 102 and the paper cushioning layer 104 are pressed together to adhere the layers together.
[0040] The web of the paper skin layer 102 and the paper cushioning layer 104 are arranged to form two panels of the mailer 100. For example, in the depicted embodiment, the web of the paper skin layer 102 and the paper cushioning layer 104 are arranged to form a first panel 106 and a second panel 108 of the mailer. When the mailer 100 is viewed as shown in Fig. 1A, the first panel 106 forms a back of the mailer 100 and the second panel 108 forms a front of the mailer 100. The web is arranged such that the paper skin layer 102 is on an outer side of each of the first and second panels 106 and 108 of the mailer 100 and the paper cushioning layer 104 is on an inner side of each of the first and second panels 106 and 108 of the mailer 100.
[0041] The mailer 100 has a bottom 1 10 and a top 112. The first and second panels 106 and 108 extend from the bottom 110 of the mailer 100 to the top 112 of the mailer 100. In the depicted embodiment, the web is one piece of the web material that has been folded such that the fold forms the bottom 110 of the mailer 100. In other embodiments, the web can be two pieces of the web material that are connected together (e.g.. adhered, sealed, etc.) to form thebottom 110 of the mailer 100. The first and second panels 106 and 108 extend upward from the bottom 110 toward the top 112. The mailer 100 also has sides 114 and 116. In some embodiments, the sides 114 and 116 are formed by connected the sides of the first and second panels 106 and 1 8 together. In some embodiments, the sides 1 14 and 1 16 can be formed by sealing, adhering, or gluing the sides of the first and second panels 106 and 108 together. In other embodiments, the sides 114 and 116 can be formed by connecting the first and second panels 106 and 108 together in any other manner.
[0042] The first panel 106 has a top 118 and the second panel 108 has a top 120. Fig. 1C depicts a detail view of a portion of the mailer 100 that includes the tops 118 and 120 of the first and second panels 106 and 108. As can be seen in Figs. 1 A and 1 C, the first panel 106 extends a first distance from the bottom 110 and the second panel 108 extends a first distance from the bottom 110, where the first distance is greater than the second distance. As can be seen in Fig. 1C, this difference in the distances that the first and second panels 106 and 108 extend upward from the bottom 110 of the mailer 100 results in an offset 122 between the tops 118 and 120 of the first and second panels 106 and 108. In some embodiments, the offset 122 between the tops 118 and 120 of the first and second panels 106 and 108 is in a range between 0.039 in (1.0 mm) and 0.197 in (5.0 mm). In some embodiments, the offset 122 between the tops 118 and 120 of the first and second panels 106 and 108 is in a range between 0.079 in (2.0 mm) and 0.157 in (4.0 mm). In some embodiments, the offset 122 between the tops 118 and 120 of the first and second panels 106 and 108 is about 0.118 in (3.0 mm). In some embodiments, the offset 122 between the tops 118 and 120 of the first and second panels 106 and 108 is less than or equal to about 0.25 in (6.35 mm). This offset between the tops 1 18 and 120 of the first and second panels 106 and 108 aid in opening the mailer 100, as discussed in greater detail below.
[0043] As can be seen in Figs. 1 A and IB, the paper skin layer 102 of the first and second panels 106 and 108 extend from the bottom 110 of the mailer 100 to the tops 118 and 120 at the top 112 of the mailer 100. However, the paper cushioning layer 104 does not extend to the tops 118 and 120. In the depicted embodiment, the paper cushioning layer 104 in each of the first and second panels 106 and 108 extends from the bottom 110 of the mailer 100 to tops 124 of the paper cushioning layer 104. The tops 124 of the paper cushioning layer 104 are closer to the bottom 110 of the mailer 100 than the tops 118 and 120 of the paper skinlayer 102. In the depicted embodiment, the tops 124 of the paper cushioning layer 104 each extend to the same distance from the bottom 110 of the mailer 100. In other embodiments, the tops 124 of the paper cushioning layer 104 extend different distances from the bottom 110 of the mailer 100. Because the tops 124 of the paper cushioning layer 104 are closer to the bottom 110 of the mailer 100 than the tops 118 and 120 of the paper skin layer 102, a gap 126 exists between the tops 124 of the paper cushioning layer 104 and the tops 118 and 120 of the paper skin layer 102.
[0044] The opening of the mailer 100 at the top 112 of the mailer 100 can be closed using the area in the gap 126 between the tops 124 of the paper cushioning layer 104 and the tops 118 and 120 of the paper skin layer 102. In the depicted embodiment, the mailer 100 includes a seal area 128 that can be sealed to close the top 112 of the mailer 100. In some embodiments, the inner sides of the paper skin layer 102 in each of the first and second panels 106 and 108 includes a sealing material. In one example, the inner sides of the paper skin layer 102 in each of the first and second panels 106 and 108 can have a polymer coating in the seal area 128, where the polymer coating will be sealed together upon application of heat to the seal area. In another example, the inner side of the paper skin layer 102 in the first panel 106 can have a first coating and the inner side of the paper skin layer 102 in the second panel 108 can have a second coating, where the first and second coatings will be adhered together upon application of pressure to the seal area. In another example, the inner side of the paper skin layer 102 of one of the first and second panels 106 and 108 can have a pressure sensitive adhesive which will adhere the first and second panels 106 and 108 together upon application of pressure to the seal area. In the depicted embodiment, the seal area 128 has a height 130 that is entirely within the gap 126. In some embodiments, the sealing material is located entirely within the gap 126. In other embodiments, the sealing material can be applied to the seal area 128 and to areas of the first and second panels 106 and 108 outside of the seal area 128. For example, where the sealing material is a polymer coating, the entirety of the inner sides of the paper skin layer of both of the first and second panels 106 and 108 can be coated with the polymer coating.
[0045] It will be noted that the offset 122 is sufficiently small that the mailer 100 does not have a typical closure flap. Typical mailers and envelopes have closure flaps that are sized to be manually folded over to close the mailer. For example, typical mailers and envelopeshave closure flaps that are at least 0.25 in (6.35 mm) wide. These closure flaps can have pressure sensitive adhesives, a wetting adhesive (e.g., gum arabic adhesive), or other adhesives that can be activated to close the envelope. The mailer 100 in the depicted embodiment does not have a closure flap because the offset 122 betw een the tops 118 and 120 of the first and second panels 106 and 108 is too small (e.g., less than or equal to about 0.25 in (6.35 mm)) for the top of the first panel 106 to be considered a closure flap.
[0046] In practice, the mailer 100 can be used to package and ship an item. The opening at the top of the mailer 100 can be opened sufficiently for a person to place the item inside of the mailer 100 and then the mailer 100 can be closed by sealing the top 112 of the mailer 100 in the seal area 128. If this process can be done entirely manually. However, performing the process completely manually can limit the number of mailers that a single person can fill in any given time period. In some instances, it w ould be advantageous for a machine to automate at least some of the process of opening, filling, and closing the mailer 100 in order to increase the throughput of a single operator.
[0047] Fig. 2 depicts an example of a machine 200 aiding in the opening of the mailer 100. In particular, the machine 200 is holding the sides 1 14 and 116 of the mailer 100 such that the top 112 of the mailer 100 is held open. The machine 200 can hold the mailer 100 in this orientation while a user inserts one or more objects into the mailer 100 through the top 112. Once all of the one or more objects to be shipped are located in the mailer 100. the machine 200 can hold the mailer 100 so that the top 112 is closed and then seal the top 112 of the mailer 100 so that the one or more objects cannot be removed from the mailer 100 without destroying some aspect of the mailer 100. These functions of the machine 200 are discussed in greater detail below.
[0048] Fig. 3 depicts a perspective view of the machine 200. The machine 200 includes a mailer conveyance device 202. In the depicted embodiment, the mailer conveyance device 202 is configured to advance discrete mailers, such as the mailer 100 described above. In some embodiments, the machine 200 holds a supply of discrete mailers, such as a supply of multiple discrete mailers that are similar to the mailer 100 described above, and the mailer conveyance device 202 is arranged to advance the discrete mailers individually from that supply. In the depicted embodiment, the mailer conveyance device 202 includes a pluralityof conveyor belts. In other embodiments, the mailer conveyance device 202 can include a single conveyor belt, driven rollers, or any other conveyance devices. In the depicted embodiment, the machine 200 further includes a mailer guide 204 that is configured to direct the mailers to a filling and sealing position. As described in greater detail below, the mailer guide 204 is configured to direct the discrete mailers from a substantially horizontal orientation, such as when the mailers are stored substantially horizontally in a supply in the machine 200, to a substantially vertical orientation for filling and sealing.
[0049] In the depicted embodiment, the machine 200 further includes a heat sealer 206. The machine 200 is capable of sealing closed mailers that can be sealed by heating the opening of the mailers. The heat sealer 206 can be a heating wire or any other heating element that extends across the width of the mailer when the mailer is held in the filling and sealing position. In the depicted embodiment, the machine 200 further includes a seal backing bar 210. At the instance shown in Fig. 3, the seal backing bar 210 is spaced apart from the heat sealer 206. When the opening of a mailer is located between the heat sealer 206 and the seal backing bar 210, the seal backing bar 210 can be moved toward the heat sealer 206 so that the seal backing bar 210 applies pressure to the opening of the mailer as the heat sealer 206 heats the opening of the mailer.
[0050] The machine 200 further includes a blower 212 that is arranged to direct a stream of gas toward the top of the mailer when it is held in the filling and sealing position. As discussed in greater detail below, the combination of the stream of gas directed to the mailer by the blower 212 and the offset in the heights of the first and second panels of the mailer causes the first and second panels of the mailer to diverge and open the opening of the mailer. This results in a simple and reliable way for the machine 200 to automatically open mailers for filling by a user. In the depicted embodiment, the machine 200 further includes a suction device 218. In the depicted embodiment, the suction device 218 is a vacuum suction cup. The suction device 218 may optionally be included in the machine 200 to engage and hold one panel of the mailer when the mailer is opened by the stream of gas from the blower 212. Engaging and holding one panel of the mailer in this manner will help to hold the mailer open until is filled by a user.
[0051] The machine 200 further includes mailer engagement devices 214 and 216. The mailer engagement devices 214 and 216 are configured to engage the sides of the mailer, such as to hold the mailer, assist in opening the mailer, close the mailer, hold the mailer closed while the opening is sealed, and the like. In the depicted embodiment, the engagement devices 214 and 216 are in the form of grippers. The engagement devices 214 and 216 can take any number of forms, such as clamps, vices, pinchers, and the like. The engagement devices 214 and 216 are configured to selectively engage and hold the sides of the mailer.
[0052] Figs. 4A to 4F each depict an instance of an embodiment of a process of the machine 200 being used to aid in opening, loading, and sealing the mailer 100. In Fig. 4A, the mailer conveyance device 202 is advancing the mailer 100. In the depicted embodiment, the mailer 100 is advanced with the bottom 110 in the front of the direction of advancement. In the depicted embodiment, the mailer 100 is advanced in a substantially horizontal direction by the mailer conveyance device 202. In the depicted embodiment, the mailer guide 204 causes the mailer 100 to transition from the substantially horizontal direction advanced by the mailer conveyance device 202 to a substantially vertical direction with the bottom 110 of the mailer 100 facing downward. The mailer conveyance device 202 is in the proceed of advancing the mailer 100 to a filling and sealing position.
[0053] From the instance shown in Fig. 4A to the instance shown in Fig. 4B, the mailer conveyance device 202 has advanced the mailer 100 until the mailer 100 is in the filling and sealing position. At the instance shown in Fig. 4B, the engagement devices 214 and 216 are gripping the sides 114 and 116 of the mailer 100 to hold the mailer 100 at the filling and sealing position. In the depicted embodiment, when the mailer 100 is in the filling and sealing position, the mailer 100 is held with the seal area 128 of the mailer vertically aligned with the heat sealer 206 of the machine 200. When the engagement devices 214 and 216 initially grip the sides 114 and 116 of the mailer 100 in Fig. 4B, the top 112 of the mailer 100 remains flat and closed (though not sealed). In that position, the top 112 is not ready for a user to insert an object into the mailer 100.
[0054] At the instance shown in Fig. 4C, the blower 212 is directing a stream of gas downward toward the top 112 of the mailer 100. In some embodiments, the stream of gas can be described as a curtain of gas. a jet of gas. a puff of gas, or any other shape and / orduration of a stream of gas. The stream of gas directed at the top 112 has caused the first and second panels 106 and 108 of the mailer 100 at the top 112 to diverge. The offset 122 between the top 118 of the first panel 106 and the top 120 of the second panel 108 causes the divergence of the first and second panels 106 and 108 of the mailer 1 0 at the top 112 when the stream of gas is directed at the top 112. When the machine 200 was attempted to be used mailers that did not have an offset (i.e., with mailers where the tops of the two panels were the same distance from the bottom of the mailer), the tops of the two panels did not reliably diverge; in many instances, the panels would be directed in the same direction resulting in the top of the mailer remaining closed. However, in the case of the mailer 100 having the offset 122 between the tops 118 and 120 of the first and second panels 106 and 108, the first and second panels 106 and 108 reliably diverge from each other when the stream of gas is directed at the top 112 of the mailer 100 by the blower 212. In this way, directing the stream of gas from the blower 212 toward the top 112 of the mailer 100 opens the top 112 of the mailer 100.
[0055] From the instance shown in Fig. 4C to the instance shown in Fig. 4D, the engagement devices 214 and 216 have been moved toward each other to exert an inward force on the sides 114 and 116 of the mailer 100. In the depicted embodiment, the movement of the engagement devices 214 and 216 includes a movement of the each of the engagement devices 214 and 216 with respect to the rest of the machine 200. In this way, the mailer 100 can remain substantially centered with respect to the machine 200 while the engagement devices 214 and 216 move with respect to each other to exert the inward force. In other embodiments, the respective movement of the engagement devices 214 and 216 can include the engagement device 214 remaining fixed with respect to the rest of the machine 200 while the engagement device 216 moves toward the engagement device 214 (or vice versa). The respective inward movement of the engagement devices 214 and 216 to exert the inward force on the sides 114 and 116 of the mailer 100 causes the top 112 of the mailer 100 to open even further.
[0056] At either or both of the instances shown in Figs. 4C and 4D, the suction device 218 may optionally be operated to engage the first panel 106. For example, the suction device 218 can be a vacuum suction cup which can be activated to selectively apply a vacuum to thepaper skin layer 102 of the first panel 106. The engagement of the first panel 106 by the suction device 218 can further assist in holding the top 112 of the mailer 100 open.
[0057] With the top 112 of the mailer 100 open as shown in Fig. 4D, the mailer 100 has been automatically prepared for filling by a user. A user can insert one or more objects to be shipping in the mailer 100 through the top 112 of the mailer 100. The engagement device 214 and 216 are configured to grip the sides 1 14 and 116 of the mailer 100 sufficiently to prevent the mailer 100 from falling due to the force of the object(s) being inserted into the mailer 100 by the user and due to the force of the weight of the object(s) after being inserted into the mailer 100. Once the user fills the mailer 100 with the object(s). an indication can be sent to the machine 200 that the machine has been filled. The indication can come in the form of a signal from a button that is pushed by the user after the mailer 100 is filled, a foot pedal stepped on by the user after the mailer 100 is filled, an optical tracking system that senses when the user fills the mailer 100, a proximity sensor that detects the number of the object(s) inserted into the mailer, and the like.
[0058] In response to the system receiving the indication that the mailer 100 has been filled, the mailer engagement devices 214 and 216 can flatten the top 112 of the mailer 100. From the instance show n in Fig. 4D to the instance shown in Fig. 4E, the mailer engagement devices 214 and 216 have flattened the top 112 of the mailer 100. In the depicted embodiment, the mailer engagement devices 214 and 216 have flattened the top 112 of the mailer 100 by pulling the sides 114 and 116 of the mailer 100 away from each other. In some embodiments, the mailer engagement devices 214 and 216 flatten the top 112 of the mailer 100 by returning the locations where the mailer engagement devices 214 and 216 initially gripped the sides 114 and 116 of the mailer 100 (e.g., at the locations of the mailer engagement devices 214 and 216 in Fig. 4B) in order to flatten the top 112 of the mailer 100.
[0059] After the top 112 of the mailer 100 has been flattened, the machine 200 can close the top 1 12 of the mailer 100. In the depicted embodiment, the inner sides of the seal area 128 of the mailer 100 are coated with a material (e.g., a polymer coating) that will seal the top 112 of the mailer 100 when subjected to heat and pressure. As shown in Fig. 4F, the seal backing bar 210 has been moved toward the heat sealer 206 so that the top 112 of the mailer 100 with the seal area 128 is pinched between the heat sealer 206 and the seal backing bar 210. Theheat sealer 206 applies heat to the top 112 of the mailer 100 while the seal backing bar 210 applied pressure to the top 112 of the mailer 100 to cause the top 112 of the mailer to be sealed closed.
[0060] One of the benefits of the machine 200 is that the machine 200 is capable of being used with mailers of different widths. For example, because the mailer engagement devices 214 and 216 are capable of moving inward and outward, the mailer engagement devices 214 and 216 can be programed to grip the sides of mailers at different positions based on a size of the mailer. In another example, the mailer engagement devices 214 and 216 can be programed to exert a different inward force one the sides of the mailer based on the size of the mailer. In another example, the mailer engagement devices 214 and 216 can be programed to pull to any of a number of different outward distances based on the size of the mailer. In another example, the mailer engagement devices 214 and 216 can be programed to be positioned at certain distances away from the heat sealer 206 (e.g.. in the horizontal direction) when holding the sides 114 and 1 16 of the mailer 100 so that the machine 200 can accommodate mailers with a number of different sizes of openings.
