TECHNICAL FIELD
[0001] The present invention relates to a secure transport container and, related thereto,
               a system and methods.
 
            BACKGROUND AND RELATED ART
[0002] There are several challenges in providing a secure container for transporting sensitive
               items by postal, courier, or similar delivery. Such items may include test tubes,
               made of glass or plastic, for holding samples of materials, substances, or fluids
               of organic and/or non-organic origins.
 
            [0003] During field conditions, collection and packing for transportation of such samples
               may be cumbersome for a number of reasons, such as the following. The sample and any
               carrier of the sample need to be kept uncontaminated. A test tube, which contains
               the sample and any carrier thereof, needs to be held securely in the container and
               needs to be sealed off such that any leakage from the test tubes is prevented from
               reaching the outside of the container. The test tubes may also need to be protected
               from contamination like moisture and dust reaching them from the outside. The test
               tubes and samples need to be protected from from impact during transportation. Easy
               handling of sample, any carrier, test tube, and the container is desirable. As is
               the easy provision of a sealing-off arrangement and impact protection of the test
               tube. Environmental aspects need to be addressed, too.
 
            SUMMARY OF THE INVENTION
[0004] The present invention aims to eliminate or at least alleviate problems or shortcomings
               in the prior art and to generally facilitate handling in relation a secure transport
               container. For these purposes, a secure transport container, system, and related methods
               are provided.
 
            [0005] Specifically, the present invention provides a secure transport container comprising:
               a front panel and a back panel joined to the front panel; a closable cavity formed
               between the front panel and the back panel and configured to hold a sealable bag;
               a first cavity closure portion attached to the front panel and a first bag sealing
               bar attached to the first cavity closure portion; a second cavity closure portion
               attached to the back panel and a second bag sealing bar attached to the second cavity
               closure portion and matable with the first bag sealing bar; wherein the first cavity
               closure portion is movable in relation to the second cavity closure portion between
               an open cavity state and a closed cavity state; wherein the first and second bag sealing
               bar are configured to be non-mated with each other in the open cavity state; wherein
               the first and second bag sealing bars are configured to be mated with each other in
               the closed cavity state and to provide between them a sealing of the sealable bag
               to be held in the closable cavity.
 
            [0006] This container has the advantage of achieving, in an uncomplicated single action,
               closure of the container's cavity and sealing of the bag in the cavity. Likewise,
               a reverse single action will open both the cavity and unseal (open) the bag.
 
            [0007] Optionally, in the secure transport container, the first and second bag-sealing bar
               are configured to provide the sealing of the sealable bag entirely inside the closable
               cavity.
 
            [0008] Providing bag sealing in this way will enable dual protection of any items, such
               as test tubes, to be located in the bag, through the sealed bag and through being
               inside the closed cavity.
 
            [0009] The secure transport container may further comprise a first locking mechanism configured
               to lock the first cavity closure portion in relation to the second cavity closure
               portion in the closed cavity state.
 
            [0010] Provision of the locking mechanism means that the container can be transported, for
               instance by mail or courier, while its contents are securely kept inside the cavity
               of the container. Preferably, the locking mechanism allows locking and unlocking a
               large number of times, which will allow re-use of the container and thus lower environmental
               impact.
 
            [0011] Optionally, in the invention, the first locking mechanism, when locked, is configured
               to hold the first bag-sealing bar mated with the second bag-sealing bar. This is a
               preferable way of arranging the locking mechanism for secure transport.
 
            [0012] The secure transport container may further comprise a second locking mechanism in
               the first and second bag sealing bars, wherein the second locking mechanism is configured
               to lock to each other the first and second bag sealing bars when mated in the closed
               cavity state. This provides additional security and assists in maintaining closure
               and sealing during transport. Typically, the second locking mechanism would operate
               entirely inside the cavity. Possibly, the second locking mechanism could be the only
               locking mechanism of the container.
 
            [0013] Optionally, in the secure transport container, the first cavity closure portion is
               formed by at least a part of the front panel. This is preferable as it allows reduction
               of design complexity.
 
            [0014] Optionally, in the secure transport container, the second cavity closure portion
               is formed by at least a part of the back panel. This is preferable as it allows reduction
               of design complexity.
 
            [0015] The secure transport container may further comprise at least one side wall joining
               the front panel and the back panel. One or more side walls contribute to form a well-defined
               cavity and a dimensionally stable cavity and container.
 
            [0016] Optionally, in the secure transport container, the first cavity closure portion is
               movably attached to the front panel the by a first hinge. This enables a well-defined
               closing and bag sealing action.
 
            [0017] Optionally, in the secure transport container, the second cavity closure portion
               is movably attached to the back panel the by a second hinge. This enables a well-defined
               closing and bag sealing action as well as a wider opening of the cavity for easy access
               for the bag to be held in the container and for items to be inserted in or removed
               from the bag.
 
            [0018] Optionally, in the secure transport container, the front panel, the back panel and,
               as applicable, the at least one side wall are made of corrugated paper, cardboard,
               corrugated plastic, sheet plastic, and/or molded plastic. These are particularly suitable
               materials. The most preferred material is corrugated paper since it has excellent
               properties for forming a box of the type described in further detail below and inherently
               provides impact protection for the box's contents. It is also well suited for postal
               or courier transport.
 
            [0019] The invention further provides a secure transport container system comprising, in
               any of its guises, the secure transport container and a sealable bag fixed inside
               the closable cavity. This system provides easy handling when inserting or removing
               items and does not require a user do handle the bag separately. It also enables fixedly
               locating the bag in a position so as to get maximum protection within the panels and
               any walls of the container. A fixed location in a center of the container should be
               preferable from this perspective.
 
            [0020] The secure transport container system may further comprise an item holder fixed inside
               the sealable bag. This will efficiently keep items, such as test tubes, in place in
               the bag. The item holder will also provide additional protection and isolate the items
               from each other in case several items are to be held.
 
            [0021] The invention further provides a method of packing items for secure transportation
               in the secure transport container system according, in any of its guises, wherein
               the method comprises the method steps of: holding the secure transport container,
               wherein the first and second cavity closure portions are in closed cavity state; unlocking
               the first locking mechanism; moving the first cavity closure portion to the open cavity
               state, by which method step the sealing of the sealable bag is removed through un-mating
               of the first and second bag sealing bars; inserting a first item in the sealable bag;
               moving the first cavity closure portion to the closed cavity state, by which method
               step the sealable bag is sealed through mating of the first and second bag sealing
               bars; locking the first locking mechanism. This is a typical field-use situation,
               wherein an item is inserted in the bag, the cavity of the container is closed and
               the bag sealed in a single action, and the container is prepared for postal, courier,
               or similar transport. This method could also comprise the removal of the first item
               from the bag prior to inserting the same first item again, for instance, after having
               used it for taking a sample in the field use situation.
 
            [0022] The invention further provides a method of packing items for secure transportation
               in the secure transport container system according, in any of its guises, wherein
               the method comprises the method steps of: unlocking the first locking mechanism; moving
               the first cavity closure portion to the open cavity state, by which method step the
               sealing of the sealable bag is removed through un-mating of the first and second bag
               sealing bars; removing the first item from the sealable bag; inserting a second item
               in the sealable bag; moving the first cavity closure portion to the closed cavity
               state, by which method step the sealable bag is sealed through mating of the first
               and second bag sealing bars; locking the first locking mechanism. This method is typically
               performed at a receiver side, such as in a laboratory or other non-field-situation.
               The removal of the first item could be made at a first instance, after which the container
               could be closed and, possibly elsewhere, be re-opened at a second instance to load
               again with a second item. This would be part of a re-use cycle for the container and,
               possibly, the bag and item holder.

            DETAILED EMBODIMENT DESCRIPTION
[0024] The drawings show details of a secure transport container, a secure transport container
               system, and methods related thereto, which will be further discussed and explained
               below. Reference numerals in the drawings are all three-digit numerals, wherein the
               first digit, being 1 through 6, indicates to which one of fig. 1 through fig. 6, respectively,
               a certain numeral pertains. The same parts are indicated with the same last two digits
               (plus a letter as the case may be) in fig. 1 and figs. 3-6. Any exception to this
               convention would be pointed of explicitly below.
 
            [0025] Fig. 1 shows a secure transport container 101, which has a front panel 102 and a
               back panel 103. The back panel 103 is joined to the front panel 102 by side walls.
               The panels 102, 103 and walls 111a, 111b, 112, 112b are made of corrugated paper.
               Further, there is a closable cavity 104 formed between the front panel 102, the back
               panel 103, and the side walls 111a, 111b, 112, 112b. The secure transport container
               101 forms a secure transport container system when combined with a sealable bag 105a,
               here made of plastic, and an item holder 105b, here made of cardboard or corrugated
               paper. The cavity 104 contains the sealable bag 105a, which is fixed by glue to the
               back panel 103. In the sealable bag 105a, the item holder 105b is glued in place and
               holds first and second test tubes 105c and 105d, here made of plastic with and each
               having a threaded lid, and being held with a loose-fit between test tube and item
               holder for easy removal and insertion. Alternatively, test tubes or other items could
               be retained by moderate friction between item and item holder.
 
            [0026] The container 101 has a first cavity closure portion 106 attached to the front panel
               102 and a first bag sealing bar 107 attached to the first cavity closure portion 106.
               Generally opposite to the first cavity closure portion 106, the container 101 has
               a second cavity closure portion 108 attached to the back panel 103 and a second bag
               sealing bar attached to the second cavity closure portion 108. As disclosed elsewhere
               in this patent application, the first and second cavity closure portions 106, 108
               define (when closed) part of the cavity 104. The first bag sealing bar 107 and the
               second bag sealing bar 109 are matable with each other in a fashion somewhat similar
               to that of a closed plastic bag clip of the type commonly used in households. However,
               the plastic bag used in the inventive system is typically thicker than household versions
               and the sealing is typically made so as to avoid creases of folds at an opening end
               of the plastic bag 105a when sealed. Moreover, the first and second bag sealing bars
               107, 109 are not attached to each other when un-mated, in an open cavity state, which
               is the state shown in fig 1. Typically, the sealable bag is generally rectangular
               with one open edge. The sealable bag 105a does not need any zipper or other type sealing
               arrangement. Rather, a bag with a sealing function of its own would probably complicate
               handling.
 
            [0027] More specifically, the first cavity closure portion 106 and second cavity closure
               portion 108 are both rotatable at respective parallel hinges 113, 114 between the
               open cavity state and a closed cavity state.
 
            [0028] As can be seen in fig. 1, the first and second bag sealing bars 107, 109 are configured
               to be non-mated with each other in the open cavity state. Further, the first and second
               bag sealing bars 107, 109 are configured to be mated with each other in the closed
               cavity state and to provide between them a sealing of the sealable bag 105a held in
               the closable cavity 103.
 
            [0029] The first and second bag sealing bars 107, 109 are configured to provide the sealing
               of the sealable bag 105a entirely inside the closable cavity 104 for protecting bag
               contents well and for protecting the surroundings from the bag contents.
 
            [0030] The container 101 has first locking mechanism 110a, 110b configured to lock the first
               cavity closure portion 106 in relation to the second cavity closure portion 108 in
               the closed cavity state. The first locking mechanism is of a dual-side-tabs-and-slots-type,
               but could alternatively be formed by centrally located locking tabs and slots. The
               first locking mechanism, when locked, is designed to hold the first bag sealing bar
               107 mated with the second bag sealing bar 109.
 
            [0031] Further, the system has a second locking mechanism 610c, 610d, 610e, 610f (in fig.
               6) in the first and second bag sealing bars 107, 109, wherein the second locking mechanism
               610c, 610d, 610e, 610f is configured to lock to each other the first and second bag
               sealing bars 107, 109 when mated in the closed cavity state. The second locking mechanism
               is essentially a spring clip and knob type of mechanism, wherein the spring clips
               and knobs are attached to respective ends of the first and second bag sealing bars
               107, 109. This locking is enhanced by friction between spring clip and knob. Further,
               it will open as the first locking mechanism 110a, 110b is released and the first cavity
               closure portion 106 and the second cavity closure portion 108 are pulled apart, which
               means entering the open cavity state.
 
            [0032] For an efficient design of the container 101, the first cavity closure portion 106
               is formed by a part of the front panel 102 and the second cavity closure portion 108
               is formed by at least a part of the back panel 103. As indicated above, the first
               cavity closure portion 106 is movably attached to the front panel the by a first hinge
               113 and the second cavity closure portion 108 is movably attached to the back panel
               the by a second hinge 114.
 
            [0033] Corrugated paper is the preferred main construction material of the container 101,
               that is, for the front panel 102, the back panel 103, the first cavity closure portion
               106, the second cavity closure portion 108 and the side walls 111a, 111b, 112. Alternatively,
               these parts can made of corrugated paper, cardboard, corrugated plastic, sheet plastic,
               or molded plastic or a combination thereof.
 
            [0034] With reference to fig. 2, the invention is also a method of packing items for secure
               transportation in the secure transport container system disclosed herein, said method
               comprising the method steps of:
               
               
holding 201 the secure transport container, wherein the first and second cavity closure
                  portions are in closed cavity state;
               unlocking 202 the first locking mechanism;
               moving 203 the first cavity closure portion to the open cavity state, by which method
                  step the sealing of the sealable bag is removed through un-mating of the first and
                  second bag sealing bars;
               inserting 204 a first item in the sealable bag;
               moving 205 the first cavity closure portion to the closed cavity state, by which method
                  step the sealable bag is sealed through mating of the first and second bag sealing
                  bars;
               locking 206 the first locking mechanism.
 
            [0035] The invention is further a method, optionally in combination with the above method
               steps, of unpacking and packing items for secure transportation in the secure transport
               container system disclosed herein, said method comprising the method steps of:
               
               
unlocking 207 the first locking mechanism;
               moving 208 the first cavity closure portion to the open cavity state, by which method
                  step the sealing of the sealable bag is removed through un-mating of the first and
                  second bag sealing bars;
               removing 209 a first item from the sealable bag;
               Inserting 210 a second item in the sealable bag;
               moving 211 the first cavity closure portion to the closed cavity state, by which method
                  step the sealable bag is sealed through mating of the first and second bag sealing
                  bars;
               locking 212 the first locking mechanism.
 
            [0036] The method aspects of this invention are related to use and re-use of the inventive
               secure transport container and secure transport container system for the purposes
               of ease-of-use and environmentally friendly re-use or re-cycling.
 
            [0037] Fig. 3 is a cross-section of the container 301 in an open cavity state showing inter
               alia the sealable bag 305a, the item holder 305b, and one test tube 305c. Further,
               some of the second locking mechanism 310c and 310d is visible at the far end of the
               bag sealing bars 307 and 309.
 
            [0038] Fig. 4 is a cross-section of the container 401 in a closed cavity state showing inter
               alia the sealable bag 405a, the item holder 405b, and one test tube 405c. Specifically,
               the sealing of the sealable bag 405a (here shown with a somewhat wider line width)
               between the first sealing bar 407 and the second sealing bar 409 is visible.
 
            [0039] Fig. 5 is an exploded view wherein the sealable bag 505a, to be located in the closable
               cavity 504, is here shown separated from the closable cavity 504 of the container
               501 in its open cavity state. Likewise the arrangement of the item holder 505b and
               two test tubes 505c and 505d, to be located in the sealable bag 505a inside the closable
               cavity 504, are here shown as a separated from the sealable bag 505a and the container
               501.
 
            [0040] Fig. 6 is the container 601 in its open cavity state, wherein the first and second
               cavity closure portions are widely opened so as to provide easy access to the test
               tubes 605c and 605d (or other items as the case may be) located in the sealable bag
               606a.
 
            [0041] Parts 610c, 610d, 610e of the second locking mechanism are visible. A fourth part
               610f thereof is located at a proximal end of the second bag sealing bar 609.
 
            [0042] The secure transport container system has a plurality of potential uses to which
               it can be adapted. For instance, outside the bag, the cavity could hold sample carriers,
               tools, napkins, cleaners, lights, spare items, instructions, stickers such as an address
               sticker, postal stamps, and (printed on inside) identification codes. The container
               could be equipped with break seal functions to indicate that any items therein are
               new, unused and/or not tampered with.
 
            [0043] As disclosed elsewhere in this patent application, a preferred feature of the inventive
               secure transport container comprises a cuboidal or similar outer shape formed by parallel
               front and back panels 102, 103 and, preferably, (when closed) parallel opposing side
               walls 111a, 111b and/or side walls 112, 112b.
 
            [0044] Another preferred feature is that the tab-and-slot-type of first locking mechanism
               (one or two tabs/slots are preferred) is locked by friction-locking between surfaces
               of a tab and inside surfaces of a slot. Cardboard material is particularly suitable
               for providing just the right amount of friction for allowing locking and unlocking
               of the first locking mechanism. Such non-destroying locking/unlocking and re-use of
               the inventive container is important for cost-efficiency and the environment. Cardboard
               material for the complete outer structure of the inventive container and the cuboidal
               shape are particularly suitable for attaining stability, low cost, efficient storage,
               and easy handling by a user, a courier or a robot.
 
            [0045] Further advantages could be attained through applying a third locking by an adhesive
               sticker, which could be of authenticity seal type, to be placed on the outside of
               the container across the first and second cavity closure portions 106, 108. Such a
               third locking would preferably be of single use type.
