Description

This application claims priority to U.S. Provisional Application No. 62/273,143 filed Dec. 30, 2015. Said application is incorporated by reference herein.

FIELD OF THE DISCLOSURE

The present invention relates to innerspring mattresses and more particularly to a packaged mattress assembly including an innerspring mattress.

BACKGROUND OF THE INVENTION

Mattresses are bulky items that are expensive to ship. Upon sale and delivery to retail customers, the mattresses must be aesthetically perfect, undamaged and clean. Mattresses typically have a fabric covering that can retain dirt, dust and debris. Such soiling is unacceptable prior to delivery to the end consumer and thus mattresses need to be protected during shipment. Mattresses may be manufactured at remote locations, for example overseas, and shipped by cargo container in ships or by truck to a destination country. At such destination country, the mattresses are shipped, typically by truck, to distributors, warehouses, retailers, and ultimately end users. It is advantageous to bag, compress, and seal mattresses at their site of manufacture prior to overseas or other distant shipment due to the reduced volume and corresponding savings in the shipment. For commodity items such as mattresses, margins can be low and any savings, in shipping, packaging, handling can be significant.

SUMMARY OF THE INVENTION

In embodiments, a mattress is bagged, compressed, and sealed at a first geographic location. A bag utilized for the bagging has an openable and closeable vent. The bagged, compressed, and sealed mattress is shipped to a destination, second geographic location. It may be warehoused in the bagged, compressed, and sealed state, and may also be further transported to distributors or retailers. At a desired point, the bagged, compressed, and sealed mattress is vented before the final end use. Such may occur before delivery to the retailer or retail customer. The vent is reclosed and the bagged uncompressed and sealed mattress is then delivered to the retailer or end user.
In embodiments, the bag is a rectilinear prism shaped form fitting bag sized to standard sized mattresses and has a closed, openable, and recloseable vent thereon before the bagging. In other embodiments, a recloseable vent is added during the process of compressing, bagging, and sealing the bagged mattress.
A feature and advantage of embodiments of the invention is that the bag in which the mattress is bagged, compressed, sealed, and shipped, from a first location to a second location is maintained on the mattress after the mattress is vented and allowed to expand to its normal size. Said bag may be resealed to keep dirt, debris, out of the packaged mattress.
A feature and advantage of embodiments is that the mattress can be vented, allowing the bagged compressed mattress to return to it original size manually without any hand tools. In embodiments the vent can be reclosed after venting without any hand tools and without adding any further materials or things.

FIG. 1 is an isometric view showing a mattress 104 in accordance with the present detailed description. In the exemplary embodiment of FIG. 1, the mattress 104 comprises an innerspring assembly including a plurality of springs. A quilted cover of the mattress 104 can be seen covering the innerspring assembly in FIG. 1. In the embodiment of FIG. 1, no external forces are acting on the mattress 104 and the mattress is free to assume a uncompressed state. With reference to FIG. 1, it will be appreciated that the mattress 104 has a thickness T1 when the mattress 104 is in the uncompressed state. With continuing reference to FIG. 1, it will be appreciated that the mattress 104 has a length L and a width W defined by a top side surface 136 and a bottom side surface 138 of the mattress 104 in the embodiment of FIG. 1.
FIG. 2 is an exploded isometric view showing a packaged mattress assembly 100 in accordance with the present detailed description. The packaged mattress assembly 100 of FIG. 2 includes a bag 102 having a bag wall 122. The bag wall 122 has an interior surface 124 and an exterior surface 126. The interior surface 124 of the bag wall 122 defines a cavity 128 that is dimensioned to receive a mattress 104. The packaged mattress assembly 100 of FIG. 2 includes a vent 130 that may be selectively opened and closed. The vent 130 comprises an adhesive strip 132 overlaying a slit 134 in the bag wall 122 in the embodiment of FIG. 2. In the embodiment of FIG. 2, the vent 130 is in a closed state with the adhesive strip 132 positioned to cover and close the slit 134 in the bag wall 122.
In the embodiment of FIG. 2, no external forces are acting on the mattress 104 and the mattress 104 is free to assume an uncompressed state. With reference to FIG. 2, it will be appreciated that the mattress 104 has a thickness T1 when the mattress 104 is in the uncompressed state. In the embodiment of FIG. 2, the cavity 128 defined by the interior surface 124 of the bag wall 122 is dimensioned to receive the mattress while the mattress is in the uncompressed state shown in FIG. 2.
Referring to FIG. 2A, in some useful embodiments, the bag 102′ is configured such that when the packaged mattress assembly 100 is in the uncompressed non evacuated state, the bag 102′ is form fit to the mattress 104. The term “form fit” may be taken to mean that the bag wall 122 of the bag 102′ generally conforms to the shape of the mattress 104 in the noncompressed state. FIG. 2B illustrates a mattress in the form fitting bag and FIG. 2C illustrates the bagged, compressed, and sealed mattress in the form fitting bag.
The form fitting bags may be about the size of standard size mattresses with extra material on one end. Examples of mattress sizes include king, queen, full, twin and crib. A king size mattress may have a width of about 76 inches and a length of about 80 inches. A queen size mattress may have a width of about 60 inches and a length of about 80 inches. A full size mattress may have a width of about 53 inches and a length of about 75 inches. A twin size mattress may have a width of about 38 inches and a length of about 75 inches. A crib size mattress may have a width of about 28 inches and a length of about 52 inches. So the mattresses are corresponding sized with some extra room for easy insertion and with extra material on an open end of the bag for sealing, see FIG. 2B. Thus the bag sizes may be, for example, as follows:


King (inches)	Queen (inches)	Full (inches)	Twin (inches)	Crib (inches)

76 to 79 width	60 to 63 width	53 to 55 width	38 to 40 width	28 to 30 width
80 to 84 length	80 to 84 length	75 to 78 length	75 to 78 length	52 to 54 length

80 to 84 length	80 to 84 length	75 to 78 length	75 to 78 length	52 to 54 length
10 to 12 depth	10 to 12 depth	10 to 12 depth	10 to 12 depth	5 to 7 depth
76 to 79 width	60 to 63 width	53 to 55 width	38 to 40 width
80 to 84 length	80 to 84 length	75 to 78 length	75 to 78 length
14 to 16 depth	14 to 16 depth	14 to 16 depth	14 to 16 depth

The bag wall (such as, for example, bag wall 122) may comprise various materials without deviating from the spirit and scope of this detailed description. In some useful embodiments, the bag wall comprises polymeric film. Polymeric film materials that may be suitable in some applications include: polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE), high density polyethylene (HDPE), low density polyethylene (LDPE) and biaxially oriented polypropylene (BOPP). The bag wall (such as, for example, bag wall 122) may have various thickness values without deviating from the spirit and scope of this detailed description. In an embodiment, the bag wall of a bag of a packaged mattress assembly has a thickness between about 10 mil and about 0.5 mil. In an embodiment, the bag wall of a bag of a packaged mattress assembly has a thickness between about 6 mil and about 1.0 mil. In an embodiment, the bag wall of a bag of a packaged mattress assembly has a thickness between about 4 mil and about 1.5 mil. In an embodiment, the bag wall of a bag of a packaged mattress assembly has a thickness of about 3 mil. In all cases, the thickness is sufficient to not allow the compressed sealed mattress bag to deform or rip to allow unintended venting of the bag.
FIG. 3 is an isometric view showing a packaged mattress assembly 100 in accordance with the present detailed description. The packaged mattress assembly 100 of FIG. 3 comprises a mattress 104 and a bag 102 having a bag wall 122. In the embodiment of FIG. 3, the mattress 104 is located inside a cavity 128 defined by an interior surface of the bag wall 122. In the embodiment of FIG. 3, the packaged mattress assembly 100 is in a compressed evacuated state.
With reference to FIG. 3, it will be appreciated that an internal pressure PI is present inside cavity 128. An external pressure PE is applied to the exterior surface 126 of the bag wall 122 by the surrounding atmosphere ATM. The internal pressure PI present inside the cavity 128 is less than the external pressure PE while the packaged mattress assembly 100 is in the compressed evacuated state shown in FIG. 3. The external pressure PE of the surrounding atmosphere is applying compressive forces on the mattress 104 due to the pressure differential between the internal pressure PI and the external pressure PE.
The packaged mattress assembly 100 of FIG. 3 includes a vent 130 that may be selectively opened and closed. The vent 130 comprises an adhesive strip 132 overlaying a slit 134 in the bag wall 122 in the embodiment of FIG. 3. In the embodiment of FIG. 3, the vent 130 is in a closed state with the adhesive strip 132 positioned to cover and close the slit 134 in the bag wall 122. When this is the case, the adhesive strip 132 may prevent de-evacuation of the packaged mattress assembly 100 so that the packaged mattress assembly 100 remains in the compressed evacuated state.
The adhesive strip 132 may be partially or completely removed from the bag wall 122 to release the packaged mattress assembly 100 from the compressed evacuated state. The packaged mattress assembly 100 may transition to the uncompressed non evacuated state when the adhesive strip is partially or completely removed to open the vent 130. Once the packaged mattress assembly 100 is in the uncompressed non evacuated state, the adhesive strip 132 may be replaced on the slit 134 to reseal the bag 102.
With reference to FIG. 3, it will be appreciated that the mattress 104 has a thickness T2 when the mattress 104 is in the compressed evacuated state. Thickness T2 is smaller than thickness T1 shown in FIG. 2. In some useful embodiments, the mattress has a reduced thickness when the packaged mattress assembly is in the compressed evacuated state and has an expanded normal thickness when the packaged mattress assembly is in the uncompressed non evacuated state.
With continuing reference to FIG. 3, it will be appreciated that the mattress 104 has a length L and a width W. In some useful embodiments, the mattress has a length and a width defined by a top side surface and a bottom side surface of the mattress and the length and width are substantially the same when the packaged mattress assembly is in the compressed evacuated state and when the packaged mattress assembly is in the uncompressed non evacuated state. The phrase “substantially the same” may be defined as within 15%, or where the mattress and structure therein is within the same footprint, but the side wall material/fabric of the mattress may upon compression may extend outwardly no more than one half the thickness of the mattress.
Various methods may be used to assemble the packaged mattress assembly 100 and to place the packaged mattress assembly in the compressed evacuated state without deviating from the present detailed description. Examples of such methods are disclosed in the following United States Patents, which patents are hereby incorporated by reference in their entirety: U.S. Pat. No. 3,611,524, U.S. Pat.

No. 1,917,535, U.S. Pat. No. 2,859,932, U.S. Pat. No. 3,600,727, U.S. Pat. No. 5,632,291, U.S. Pat. No. 8,579,870, U.S. Pat. No. 4,924,899, U.S. Pat. No. 6,960,113, U.S. Pat. No. 3,141,261, and U.S. Pat. No. 4,758,198.
In the embodiment of FIG. 3, the adhesive strip 132 comprises a tab 140 configured to be grasped between a thumb and a finger of a hand. In some useful methods in accordance with this detailed description, the bag 102 may remain in position surrounding the mattress 104 while the mattress 104 is handled, stored and transported. When this is the case, the bag will serve to protect the mattress 104 from soiling, staining and abrasion while the mattress 104 is handled, stored and transported.
FIG. 4A through FIG. 4D are a series of stylized isometric views illustrating the operation of vent 130 shown in the previous figure. FIG. 4A through FIG. 4D may be collectively referred to as FIG. 4. Two portions of a bag 102 are shown in FIG. 4. Bag 102 of FIG. 4 comprises a bag wall 122 having an interior surface 124 defining a cavity 128. A vent 130 is also visible in FIG. 4. The vent 130 comprises an adhesive strip 132 and a slit 134 defined by the bag wall 122 in the embodiment of FIG. 4.
In FIG. 4A, the adhesive strip 132 of vent 130 can be seen overlaying the slit 134 in the bag wall 122. The adhesive strip 132 is positioned to cover and close the slit 134 in the bag wall 122 in the embodiment of FIG. 4A. With reference to FIG. 4A, it will be appreciated that an internal pressure PI is present inside cavity 128. An external pressure PE is applied to the exterior surface 126 of the bag wall 122 by the surrounding atmosphere ATM. In the embodiment of FIG. 4A, the internal pressure PI is less than the external pressure PE.
In some cases, the internal pressure PI present inside cavity 128 may be less than the external pressure PE while a mattress located inside the cavity 128 is in a compressed evacuated state. When this is the case, the adhesive strip 132 may prevent de-evacuation of the mattress 104 and the bag 102 may maintain the mattress 104 in the compressed evacuated state. In the embodiment of FIG. 4, the vent 130 may be selectively opened and closed. The vent 130 may be opened, as desired, for transitioning the packaged mattress assembly 100 from a compressed evacuated state to an uncompressed non evacuated state. Opening the vent 130 may allow the internal pressure PI to equalize with an external pressure PE of the surrounding atmosphere ATM.
In FIG. 4B, a tab 140 of the adhesive strip 132 can be seen being grasped between a thumb and a finger of a hand. In the embodiment of FIG. 4, the tab 140 is formed by folding a substrate 142 of the adhesive strip 132 so that a first portion 146 of the substrate 142 overlaps a second portion 148 of the substrate 142. An adhesive covering of the adhesive strip 132 may adhere the first portion 146 to the second portion 148. In FIG. 4B, a portion of the adhesive strip 132 has been peeled away from the bag wall 122 so that a small portion of the slit 134 is uncovered. However, most of the slit 134 remains covered by the adhesive strip 132 in the embodiment of FIG. 4B.
FIG. 4C is an additional isometric view showing adhesive strip 132 and slit 134 of vent 130. With reference to FIG. 4C, it will be appreciated that the adhesive strip 132 comprises an adhesive layer 144 overlaying a substrate 142. By comparing FIG. 4C with FIG. 4B, it will be appreciated that the tab 140 of adhesive strip 132 has been pulled further in a direction D in the embodiment of FIG. 4C relative to the embodiment of FIG. 4B. Pulling tab 140 in direction D has caused more of the slit 134 to be uncovered in the embodiment of FIG. 4C.
With continuing reference to FIG. 4C, it will be appreciated that the vent 130 has been opened by peeling the adhesive strip 132 away from a portion of the slit 134. In the embodiment of FIG. 4A, an internal pressure PI is present inside cavity 128 defined by an inner surface xx 124 the bag wall 122. An external pressure PE is applied to the exterior surface 126 of the bag wall 122 by the surrounding atmosphere ATM. Opening the vent 130 has allowed the internal pressure PI to equalize with the external pressure PE in the exemplary embodiment of FIG. 4C.
If desired, the adhesive strip 132 may be replaced over the slit 134 after the pressure has equalized thereby closing the vent 130. In some useful methods in accordance with this detailed description, the bag may remain in position surrounding the mattress while the mattress is handled, stored and transported. When this is the case, the bag may serve to protect the mattress from soiling, staining and abrasion while the mattress is handled, stored and transported.
FIG. 4D is an additional isometric view showing the slit 134 in the bag wall 122. In the embodiment of FIG. 4D, the adhesive strip has been completely separated from the exterior surface 126 of the bag wall 122. Accordingly, the slit 134 is completely unobstructed in the embodiment of FIG. 4D.
In an embodiment, a packaged mattress comprises a mattress and a bag having a bag wall. The bag wall may carry an openable and closeable valve in fluid communication with a cavity defined by the bag wall for providing the necessary venting when the bagged, compressed, and sealed mattress is converted to the bagged uncompressed mattress. A packaged mattress assembly may include various valves without deviating from the spirit and scope of this detailed description. Examples of such valves are disclosed in the following United States Patents, which patents are hereby incorporated by reference in their entirety: U.S. Pat. No. 1,555,373, U.S. Pat. No. 1,917,535, U.S. Pat. No. 2,859,932, U.S. Pat. No. 3,600,727, U.S. Pat. No. 5,632,291, and U.S. Pat. No. 8,579,870. Generally these valves will be attached to the bags before the bags are provided for the bagging, compressing, and sealing the mattresses.
FIG. 5 is a flowchart illustrating an exemplary method in accordance with this detailed description. At block 150A of the flowchart, a packaged mattress is transported in a bag in a compressed evacuated state from a first geographic region to a second geographic region. In some useful embodiments, the first geographic region is proximate to a mattress manufacture location and the second geographic region includes locations in which the retail sale of mattresses is conducted. In some embodiments, the first geographic region and the second geographic region are more than 1,000 miles away from one another.
FIGS. 6-10 illustrate steps that may provide variations of the method illustrated in FIG. 5. Any or all of the steps of FIG. 5 may be replaced with any combination of the steps of FIGS. 6-10 in embodiments.
In some useful embodiments, the packaged mattress may be disposed inside an intermodal shipping container while the packaged mattress is transported from the first geographic region to the second geographic location. The intermodal shipping container may be transported using ocean going vessels, railroads, airplanes, and/or over-the-road vehicles. Intermodal shipping containers that may be suitable in some applications are disclosed in the following United States Patents, which patents are hereby incorporated by reference in their entirety: U.S. Pat. No. 2,853,968, U.S. Pat. No. 4,082,051, U.S. Pat. No. 7,827,738, and U.S. Pat. No. 9,004,832.
At block 150B, an openable and closeable vent on the bag is opened at the second geographic region to release the packaged mattress from the compressed evacuated state to an uncompressed non evacuated state. In some useful embodiments, the step of opening an openable and closeable vent on the bag at the second geographic region occurs at a warehouse of a retail distributor or a wholesale distributor. In other useful embodiments, the step of opening an openable and closeable vent on the bag at the second geographic region occurs in or proximate to a delivery vehicle that delivers the packaged mattress to an end user who has purchased the mattress.
At block 150C, the openable and closeable vent is closed at the second geographic region. In some useful methods in accordance with this detailed description, the vent may be resealed and the bag may remain in position surrounding the mattress while the mattress is handled, stored and transported. When this is the case, the bag may serve to protect the mattress from soiling, staining and abrasion while the mattress is handled, stored and transported.
At block 150D, the uncompressed non evacuated packaged mattress is delivered with the closed vent to an end user who has purchased the mattress.
Various methods may be used to assemble a packaged mattress assembly and to place the packaged mattress assembly in a compressed evacuated state without deviating from the present detailed description. Such methods may include the step of providing a plurality of suitably sized bags. Each bag may comprise a bag wall having an interior surface defining a cavity. Each bag may also include a vent configured to be selectively opened and closed. For example, the vent may comprises an adhesive strip overlaying a slit in the bag wall.
A mattress may be inserted into the cavity of each bag. The bag and the mattress may then be placed in a hydraulic press capable of compressing the mattress. The mattress may then be compressed using the hydraulic press. As the mattress is compressed, air will be expelled from the cavity of the bag. If desired, additional air may be removed from the cavity of the bag using one or more vacuum pumps. An opening of the bag may be sealed. In some cases, a heat sealing process may be used to seal the opening of the bag. For example, the bag wall me be squeezed between two heated bars covered with Teflon coated fiberglass causing the inner surface of the bag wall to be welded to itself along a heat seal line.
