The present invention involves a shipping container in which the container's contents are under vacuum. By employing this invention, the bulk volume of a shipping container can be reduced resulting in significant cost savings.
It has become increasingly apparent that as time goes on, manufacturing has shifted to remote locations where labor costs are less than those in this country. This is particularly true as it pertains to the manufacture of non-technical or relatively low end products which rely upon various unskilled but labor intensive operations. However, as manufacturing has shifted to off shore locations, shipping costs have become an increasingly more significant factor in establishing product pricing.
Typically, manufactured goods produced in Asia are imported into the United States on containerized vessels. These goods are not only manufactured but packaged at Asian factories and multiple units placed within cardboard containers or otherwise bundled in groups for placement within cargo containers which are, in turn, stacked atop appropriately configured vessels. The shipping cost per item is dictated by the number of such items which can be placed within such shipping containers as the cost per transoceanic passage substantially remains fixed.
Certain items, such as televisions, stereos, computers and semiconductor chips are configured with hard outer casings and there is little that a shipper can do to reduce shipping costs. In these instances, one would only try to maximize stacking efficiencies in order to take full advantage of shipping container volumes. However, the situation is considerably different for products such as pillows, blankets, bedding and plush novelty items which possess large volumes of air or otherwise compressible space. In those instances, shipping costs could be significantly reduced if the volumes of such products were reduced in order to enable a shipper to incorporate more unit items per container.
Vacuum packing has been available to a multitude of users varying from home consumers who wish to preserve food products to those wishing to store soft goods for long periods of time. In each instance, a plastic membrane is placed about an object and vacuum drawn in order to reduce internal volume by collapsing the plastic membrane onto its contents.
Although vacuum sealing in the creation of packaging for manufactured goods may have been contemplated by others, in each instance, these plastic enclosures have not been fabricated to act as their own shipping containers. Invariably, plastic enclosures, be they vacuum sealed or otherwise, are housed in outer protective enclosures, such as printed cardboard boxes in order to protect the inner plastic wrap from anticipated abuse incurred during shipping. This anticipated shipping damage is particularly of concern when dealing with vacuum sealed enclosures for a single puncture or abuse-induced breakage can cause a loss of internal vacuum resulting in potentially catastrophic consequences. A loss of internal vacuum could compromise the integrity of perishable goods while bulk items whose volumes have been reduced as a result of the application of suitable vacuum pressures could expand during shipping resulting in damage to the containerized vessel and adjacent packaged goods.
In addition to the above concerns, it is quite apparent that “double packaging” in terms of providing a vacuum creating shroud about an object which is then encased in an outer abuse-resistant shipping package adds yet a further cost which must be absorbed by the ultimate consumer.
It is thus an object of the present invention to provide vacuum packaging in order to reduce shipping volume and thus cost of a wide range of manufactured goods.
It is a further object of the present invention to provide vacuum packaging which can act both as a vacuum induced volume reducing shroud but also as a shipping container without the need for any external outer protective expedience.
These and other objects will be more readily appreciated when considering the following disclosure and appended claims.
The present invention is directed to a shipping container for shipping bulky, compressible contents under vacuum and at a reduced volume. The shipping container comprises a plastic body sized to receive and envelop its contents. The plastic body, itself, comprises a top, a bottom, each of which having a periphery, and side walls, the latter of which are compressible. A stem is provided through the plastic body for the passage of air and for selective sealing after air has passed therethrough. The top, bottom and side walls are of a sufficient thickness and durability as to enable the shipping container to be shipped between remote locations without any protective packaging being applied thereto while substantially resisting damage to the shipping container and its contents.
a and 5b show alternative embodiments of the present invention taken along cross-section 5-5 of
As noted previously, the present invention is directed to a shipping container for shipping bulky, compressible contents under vacuum while substantially resisting damage to the shipping container and its contents. In this regard, reference is made to
Turning to
As a further preferred embodiment, it is contemplated that at least a portion of shipping container 20, and preferably its top 5 be substantially transparent. As noted by reference to
As previously noted, it has been determined that a reduction in shipping container volume, in passing between the iterations shown in
To further make the present invention more resistant to shipping damage, it is proposed, as a preferred embodiment, reinforcement be applied to strategic portions of shipping container 20. For example, strands 26 can be molded at the peripheries 31 of top 5 and bottom 6 as shown in various cross-sectional views as well as in the respective view of
As a further expedient which can be used in conjunction with strands 26 or as an alternative thereto, it is contemplated that container 20 be provided with reinforced corner portions 35 as it is anticipated that, during shipment, the abuse inflicted upon shipping container 20 is likely to be manifested at the corners where top 5 and bottom 6 join side walls 7 and 8.
It is recognized that when subjected to extreme abuse, any shipping container, including container 20 could be ruptured thus compromising the vacuum created therein resulting in an expanded volume imposed upon shipping container 20 by pillow 10. As a further expedient, it is proposed that shipping container 20, once placed under vacuum in its reduced volumetric state as shown in
Once the shipping process has been completed and a consumer wishes to access the interior of shipping container 20 in order to remove pillow 10, several alternative expedients can be employed. In referring to
Various embodiments and iterations of the shipping container have been described above. Other modifications and embodiments will suggest themselves to those of ordinary skill in the art. Thus, it is intended that this invention be limited solely by the scope of the allowed claims.
