This disclosure relates generally to portable insulated containers for objects, such as shipping containers for medical or scientific items.
It is often desirable to ship or store medical supplies, samples, specimens, scientific samples, and/or other items while keeping them within a specified or predetermined temperature range. Exposure, particularly to temperatures outside the predetermined temperature range, may render the items damaged or unusable. It may also be desirable to provide some degree of physical protection to the items being shipped.
Currently available shipping containers may suffer from one or more disadvantages, such as requiring large volumes of ice or other coolant(s) to maintain the temperature of the items within the predetermined range. Even during more moderate environmental temperatures, some items may not be shipped if the expected delivery time exceeds the capacity of the shipping container to maintain the predetermined temperature range. Medical items and specimens can be particularly sensitive to temperature changes. Lower quality or inexpensive containers often require more ice to ensure that the items are kept cool during the entire shipping process.
It is therefore desirable to be able to ship these types of items in a container providing improved temperature protection with a higher degree of insulation and protection to better maintain the temperature within the chamber within a predetermined temperature range.
Insulated shipping containers are used for a variety of purposes and in conjunction with a variety of activities. A container may be insulated to assist in keeping one or more items cool, cold, frozen, warm, or hot. The container may also be used to protect one or more items from damage, bumps, impact, light, and/or contaminants. While most of the examples discussed herein are discussed with respect to a container for keeping the contents cool, it should be understood that the techniques and features disclosed herein are applicable to other types of shipping, storage, or temperature control containers, including containers for keeping items warm or hot. The containers disclosed herein may have multiple components and may be configured in the form of a system or kit. The containers disclosed herein may be configured to be carried or transported in a plurality of manners or configurations.
In one example, an insulated shipping container system for transporting temperature sensitive specimens includes an insulated body, an insulated lid, and a stretchable strap. The insulated body has an internal cavity that is accessible through an opening or aperture and has a cross-sectional shape. The insulated lid is configured for selectively closing the opening to the internal cavity when the lid is in a closed position. The stretchable strap is removably attachable to each of the insulated body and the insulated lid. The stretchable strap is configured to stretch and attach to a lug on the insulated body to selectively hold the insulated lid in the closed position and further configured to retain the insulated lid to the insulated body when the lid is in an opened position. The insulated shipping container system may also include a freezable cold pack having a shape corresponding to the cross-sectional shape of the internal cavity. The insulated shipping container system may also optionally include a shipping case configured to cover the insulated body and the insulated lid when the insulated lid is in the closed position. The insulated shipping container system may also optionally include a spacer for reducing movement of items inside the container.
Other variations and embodiments are possible, including variations and embodiments which do not necessarily include all of the elements described above and/or variations and embodiments which may include additional elements.
The walls of insulated body 102 and/or insulated lid 101 include one or more forms of insulation for maintaining a preferred temperature or temperature range during shipping. In one specific example, insulated body 102 and/or insulated lid 101 may include inner and outer walls which are separated by an internal space between the walls which is evacuated to create a vacuum insulated wall structure. Vacuum insulated walls can provide high performance insulation characteristics. In some examples, body 102 and/or insulated lid 101 may be constructed of a metallic material, such as stainless steel. Shipping container 100 also includes removably strap 105.
Strap 105 includes one or more attachment features, such as aperture 113, configured to engage with one or more attachment features of insulated lid 101, such as cleat 109 and/or cleat 111, for removably attaching strap 105 to insulated lid 101. Strap 105 also includes one or more attachment features, such as aperture 114, configured to engage with one or more attachment features of insulated body 102, such as lug 107. When strap 105 is removably attached to insulated lid 101 and insulated body 102 it can be used to temporarily hold insulated lid 101 in the closed position illustrated in
The insulated shipping containers or shipping container kits or systems disclosed herein may be used for storing or shipping any item or items that must be controlled or kept within particular temperature ranges. In some examples, one or more medical items, materials, scientific samples, or specimens may be stored or stored or shipped in one of the of insulated shipping containers or shipping container kits or systems disclosed herein.
In some examples, the shipping container kit or system may include one or more spacers of various sizes. The spacer(s) may be configured to occupy any remaining space in the internal cavity after one or more specimen trays have been inserted. The spacers may be shaped to fit the internal cavity of the shipping container similar to cold pack 502. The spacers may take up remaining space and reduce or eliminate movement of the specimen trays during shipping and/or provide additional insulation.
Any of the techniques, improvements, features, functions, or processes described herein may be implemented in the form of a system or a kit. The system or kit may include any combination of the devices, components, elements, and/or modules disclosed herein.
The techniques, elements, components, methods, and steps described herein are meant to exemplify some types of possibilities. In no way should the aforementioned examples limit the scope of the invention, as they are only exemplary embodiments.
The phrases “in some embodiments,” “according to some embodiments,” “in the embodiments shown,” “in other embodiments,” “in some examples,” “on other examples,” “in some cases,” “in some situations,” “in one configuration,” “in another configuration,” and the like generally mean that the particular technique, feature, structure, or characteristic following the phrase is included in at least one embodiment of the present invention and/or may be included in more than one embodiment of the present invention. In addition, such phrases do not necessarily refer to the same embodiments or to different embodiments.
The foregoing disclosure is presented for purposes of illustration and description. Other modifications and variations may be possible in view of the above teachings. The embodiments described in the foregoing disclosure were chosen to explain the principles of the concept and its practical application to enable others skilled in the art to best utilize the invention. It is intended that the claims be construed to include other alternative embodiments of the invention except as limited by the prior art.
This application claims priority to U.S. Provisional Patent Application No. 63/236,792, filed Aug. 25, 2021, which is hereby incorporated by reference in its entirety.
