Description




FIELD OF THE INVENTION




This present invention relates to a shipping container and, more particularly, to a shipping container whereby pharmaceuticals or the like can be shipped with temperature protection.




BACKGROUND OF THE INVENTION




There exist numerous temperature controlled containers that include various types of refrigeration systems, for example, ice in a portable food storage chest. The need has existed, for some time, to store and ship foods, confections, drugs and the like at lower than ambient temperatures to prevent spoilage or other forms of degradation prior to actual use of the product. It is noted that temperature controlled shipping containers are generally designed for a specific use.




In particular, if drugs or pharmaceutical items are to be shipped it may be critical that a certain predetermined temperature range or level be maintained. On the other hand, if biological degradation is to be slowed in the shipment of, for example, sterile penicillin, another temperature and another type of container must be used. Likewise, standard containers such as Styrofoam chests or other types of refrigeration means, such as ice, have been well known in the prior art and each is adapted to a specific use. However, in the storage and transportation of pharmaceutical substances, serum, vaccines and the like, measures must be taken to insure that the object to be shipped or stored can be constantly kept within a predetermined temperature range. To date this type of storage container is expensive because it is specifically constructed to a particular need.




One such temperature protected container is an assembly that includes a plurality of retention members and a temperature control means. The container includes both an outer protective layer and an inner insulating layer. The outer protective layer and the insulating layer define a shipping cavity containing the liquid retention members and the temperature control means. However, the container is expensive to construct and the cooling means are ice blocks, which must be kept refrigerated prior to use in a waterproof bag or container. The use of ice is both time consuming and irritating, wherein the ice requires an exterior refrigeration system for them to work and does not evenly absorb heat from the object being kept cool. The use of this container with ice packs is not convenient as the ice melts and the remaining liquid must be disposed of prior to using the container again. Finally, this container is difficult to pack and cumbersome to carry.




What is needed is a temperature protected container that is inexpensively constructed, disposable, and carries two off the shelf bottles of penicillin, and the like, that are used on livestock. What is further needed is a temperature-protected container with a cooling means that is simple to use and reusable. Finally, what is also needed is a temperature-protected container that is easy to assemble.




SUMMARY OF THE INVENTION




It is an aspect of this invention to provide a thermally protected container that is inexpensively constructed, disposable, and carries two of the shelf bottles of penicillin, and the like, that are used on livestock.




It is another aspect of this invention to provide a thermally protected container that includes a cooling means that is simple to use and reusable.




It is yet another aspect of this invention to provide a thermally protected container that is easy to assemble.




To accomplish these and other aspects of this invention, a shipping apparatus includes a container with a closeable top for carrying pharmaceuticals and a cooling means for keeping the pharmaceuticals temperature protected. The apparatus further includes a retention means within the container for positioning and securing the pharmaceuticals and cooling means, and a gripping means for transporting the container.




A method of using a shipping apparatus includes the steps of assembling a container with a closeable top for carrying pharmaceuticals, activating, and inserting a cooling means into a retention means of the container for keeping said pharmaceuticals temperature protected. The steps further include inserting the pharmaceuticals into the retention means within the container for positioning and securing the pharmaceuticals, closing the top of the container and engaging a gripping means for transporting the container.

12


and a second closeable top


13


. The container is typically, in the preferred embodiment of the invention, rectangular in shape carrying a first pharmaceutical


14


and a second pharmaceutical


15


that are normally an off-the-self-size. The pharmaceutical industry standard for the first pharmaceutical


14


and the second pharmaceutical


15


are bottles of about 500 mL in size. Typically, the container


11


that carries two 500 mL bottles has an overall dimension of about 3.50 inches deep by 6.50 inches high by 7.00 inches long. However, the container


11


rectangular shape is substitutable for a square shape, a circular shape, an oval shape or any polyhedron shape that is desired. The container


11


volume depends on the size of the first pharmaceutical


14


and the size of the second pharmaceutical


15


. In another embodiment of the invention the first and second pharmaceuticals are added to and include three and four, or more, pharmaceuticals wherein the container has an increase in volume to carry the additional pharmaceuticals. The larger in size the pharmaceuticals and the larger in number the pharmaceuticals the greater the volume of container


11


. Likewise it is comprehensible that container


11


would carry only one pharmaceutical wherein the volume of container


11


would be smaller than the preferred embodiment of the invention.




The first pharmaceutical


14


is positioned into a first retention means


43


that includes a first inner wall


17


, a second inner wall


18


, a third inner wall

35


and third retention structure


31


secures the first pharmaceutical


14


, inside the first cavity


43




a


, preventing the first pharmaceutical from spilling. As is understood by the practitioner in the art the first cavity


43




a


varies in size depending on the size of the first pharmaceutical


14


which in the preferred embodiment of the invention is a 500 mL bottle of liquid medicine or the like. The first pharmaceutical


14


is substitutable by other packages, for example, solid chemicals that will also vary in size. This will also vary the size of the first cavity


43




a.






The second pharmaceutical


15


is positioned into a third retention means


45


that includes a fifth inner wall


23


, a sixth inner wall


24


, a seventh inner wall


25


, an eighth inner wall


26


and bottom


35


whereby forming a third cavity


45




a


. The second pharmaceutical


15


is further retained by a fourth retention structure


32


. The combination of the inner walls, the bottom and fourth retention structure


32


secures the second pharmaceutical


15


, inside the third cavity


45




a


, preventing the second pharmaceutical from spilling. As is understood by the practitioner in the art, the third cavity


45




a


varies in size depending on the size of the second pharmaceutical


15


which in the preferred embodiment of the invention is a 500 mL bottle of liquid medicine or the like. The second pharmaceutical


15


is substitutable by other packages, for example, solid chemicals that will also vary in size. This will also vary the size of the third cavity


45




a.






A cooling means


16


is positioned and secured in a second cavity


44




a


by a second retention means


44


. The cooling means


16


provides temperature protection to the first and second pharmaceuticals. This serves the dual function of providing direct transfer of cooling energy to the first pharmaceutical


14


and the second pharmaceutical


15


while at the same time making the most economical use of the cooling means


16


. The retention means


44


is formed by the bottom


35


, a first retention structure


21


with a ninth inner wall


21




a


and a second retention structure


22


with a tenth inner wall


22




a


. The first top


33


of the first retention structure


21


and the second top


34


of the second retention structure


22


form the gripping means


46


. As is understood by the practitioner of the art the second cavity


44




a


is a variety of sizes depending on the size of the cooling means


16


. The second cavity


44




a


is formed and separated from the first cavity


43




a


by the first retention structure


21


because cold spots my result in the first pharmaceutical


14


without this separation and consequently crystallize and freeze the first pharmaceutical. Likewise, the second retention structure also serves the purpose of eliminating cold spots in the second pharmaceutical


15


.




The cooling means


16


is typically a refrigerant gel pak. The gel pak is substitutable for refrigerant foam bricks or gel bottles. The gel paks, gel bottles and foam bricks stay frozen longer than ice due to a slow and even rate of heat absorption. The refrigerant gel paks and foam bricks vary in size, freezing points and gel structures depending on the application. For example, the variety of gel paks include a polymer gel encased in a 5 mil polyethylene pouch, a food safe non-toxic gel encased in a trilaminate foil, gel bottles and a suppressed temperature gel encased in a trilaminate foil. The suppressed temperature gel, for example, has a −10° F. freezing point. Furthermore, the purpose of this type of packaged refrigerant is to prevent contamination and moisture exchange as well as to prevent molten refrigerant from contaminating the goods being thermally shielded.




Another refrigerant that is usable is a foam brick. For example, sodium sulfate decahydrate or calcium chloride hexahydrate is absorbed into a block of open cell phenol-formaldehyde foam and contained in a polyethylene bag closed by heat sealing. Any chemical refrigerant selected should have a melting point about 3 to about 5° C. below the thermo-sensitive temperature of the first pharmaceutical


14


and second pharmaceutical


15


. Furthermore, the purpose of this type of packaged refrigerant is to prevent contamination and moisture exchange as well as to prevent molten refrigerant from contaminating the goods being thermally shielded.




The apparatus


10


, container


11


, in the preferred embodiment of the invention, is constructed as a corrugated box board from fibrous material such as liner board, box board, card board and the like. These materials include, but are not limited to, medium weight box board, heavy weight box board, light weight box board, structured foam, plastic, laminated plastic, and the like. The voids


47


that are formed between the outer and inner walls of container


11


, as is readily understood by the practitioner in the art, are typically formed by a corrugated box board construction. Furthermore, the voids


47


that are integral to the construction of corrugated box board are, in the preferred embodiment of the invention are filled with air. However, depending on the application the voids


47


are filled with insulating foam or other insulating materials. Consequently, this enhances the cooling means


16


by slowing the heat absorbed from outside container


11


that would be transferred to the first pharmaceutical


14


and the second pharmaceutical


15


. Alternately, if structured foam is used instead of just box board in the container


11


, the structured foam is used as an inner insulating layer while and outer layer still consists of the box board, plastic or laminated plastic.




The insulating foam that fills the voids


47


typically comprises a plastic type material. This is to keep container


11


as light weight as possible, yet dramatically enhance the thermal resistance of the walls of container


11


. Furthermore, it has been shown that polystyrenes, polyurethanes and other polymeric materials, such as insulating vinyl nitrile, have well known foaming characteristics. It can be stated that the better the thermal insulating properties that the foam material exhibits, the more utility it will have in another embodiment of the present invention.
