Summary of the Invention

[0005] The inventors of the present invention have focused on the fact that when viscous materials are transported in a transport container containing dry ice, as described in Patent Document 1, supercooling occurs, affecting product performance, and have been diligently investigating this issue. Specifically, there is a risk that the viscous material may crystallize due to supercooling, or that separation and sedimentation may occur when the viscous material is thawed after supercooling. Furthermore, the inventors of the present invention are concerned that when a vacuum insulating material is used in the transport container, as described in Patent Document 2, the weight of the transport container becomes relatively heavy, and the amount of viscous material that can be transported at one time becomes relatively small.

[0006] Therefore, the present invention has been made to achieve the above-mentioned problems, and aims to provide a syringe transport device set, a syringe transport method, a packaging member, and a method of using the packaging member that can suppress temperature fluctuations of a viscous material in response to temperature fluctuations of the outside air using a configuration other than a vacuum insulation material, and that can prevent or suppress supercooling of the viscous material.

[0007] A syringe transport device set according to one aspect of the present invention, which solves the above problems, comprises a surrounding member and a cooling agent. The surrounding member is installed in the containment space of the packaging container, surrounds a syringe equipped with a material storage container for containing a viscous material, and includes a cushioning member to mitigate external forces applied to the syringe during transport. The cooling agent is installable between the syringe and the surrounding member in the containment space, and comprises a contents for keeping the syringe cool and a contents storage container for containing the contents. The enclosing member comprises a packaging member capable of packaging at least a portion of the syringe. The packaging member has an insertion portion into which the syringe can be inserted in an upright position, and a solid portion provided around the insertion portion and forming the insertion portion. The solid portion is formed from a first end on the side where the insertion portion is located to a second end on the opposite side of the first end in the direction in which the viscous material is inserted into the insertion portion, and contains non-crosslinked foamed polyethylene. The buffer material has a thermal conductivity of 0.022 W / m·K or less, and the contents are composed of materials with a melting point of -30 degrees Celsius or lower.

[0008] Furthermore, in one aspect of the present invention, a syringe transport method involves placing the syringe in the storage space of the above-mentioned packaging container. Then, a cooling agent is placed in the storage space so as to surround the syringe. Then, a surrounding member is placed in the storage space so as to surround the syringe via the cooling agent.

[0009] Furthermore, one aspect of the present invention is a packaging member for holding the syringe, and a method for using the packaging member. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. The embodiments shown herein are illustrative examples for embodying the technical idea of ​​the present invention and do not limit the present invention. Furthermore, all other implementable forms, examples, and operational techniques that can be conceived by those skilled in the art without departing from the spirit of the present invention are included in the scope and spirit of the present invention, as well as in the claims and their equivalents.

[0012] Furthermore, the drawings attached to this specification may be schematically represented with changes to scale, aspect ratio, shape, etc., from the actual object for the sake of illustration and ease of understanding, but these are merely examples and do not limit the interpretation of the present invention.

[0013] In the following description, ordinal numbers such as "first" and "second" are used for convenience of explanation and do not define any order unless otherwise specified.

[0014] In the following, a coordinate system is used in the drawings and their descriptions. X and Y are the planar directions in which the packaging member 210, the buffer member 250, and the cold storage agent 300 are placed, and are referred to as the first direction X, the second direction Y, or the planar direction XY. Z corresponds to the height direction of the packing container 100 and the packaging member 210, and is referred to as the height direction Z.

[0015] (Syringe) The syringe 500 is used by setting a viscous material in an application device such as a dispenser. The syringe 500 includes a material storage container 510 and a lid portion 520 as shown in FIG. 5. The syringe 500 can be installed in the storage space Sp (see FIG. 1) of the packing container 100.

[0016] The material storage container 510 is configured to provide a semi-closed space Sc for storing the viscous material. The material storage container 510 has an opening 511 through which the viscous material can be discharged from the semi-closed space Sc as shown in FIG. 6. The material storage container 510 can be provided with a plunger 530 at an intermediate portion in the height direction Z as shown in FIG. 6.

[0017] The plunger 530 can move in the height direction Z to move the viscous material filled in a sealed state in the semi-closed space Sc toward the opening 511. The plunger 530 is provided at the center in the height direction Z of the material storage container 510 in the present embodiment, but the position of the plunger is not limited to the center in the height direction Z as long as the viscous material can be stored in the semi-closed space Sc.

[0018] The material storage container 510 is configured to have a pointed or curved surface shape at the tip in the height direction Z of a substantially cylindrical shape. However, the specific shape is not limited to the above as long as a semi-closed space for storing the viscous material can be formed.

[0019] The lid portion 520 is attached near the end opposite to the opening 511 in the height direction Z in a state where the viscous material is stored in the semi-closed space Sc of the material storage container 510. The syringe 500 stores the viscous material in the semi-closed space Sc of the material storage container 510, and the material storage container 510 can be installed in a dispenser or a coating device in a state where the lid portion 520 is removed from the material storage container 510.

[0020] Specific examples of the viscous material transported by the syringe transport tool set 1 according to the present embodiment include, for example, adhesives, sealants, coating agents, conductive adhesives, thermally conductive resins, flame-retardant resins, etc. Among them, adhesives, sealants, conductive adhesives, and thermally conductive resins are preferred because the temperature fluctuation of the viscous material with respect to the temperature fluctuation of the outside air can be further suppressed. Particularly preferred are adhesives and conductive adhesives.

[0021] The components of the viscous material are not particularly limited, and examples include urethane resins, epoxy resins, oxetane resins, (meth)acrylic resins, silicone resins, etc. Among them, epoxy resins, oxetane resins, and (meth)acrylic resins are preferred, and particularly preferred is an epoxy resin. By using more preferable components, the temperature fluctuation of the viscous material with respect to the temperature fluctuation of the outside air can be further suppressed.

[0022] The viscosity of the viscous material is not particularly limited, but a range of 0.1 to 150 Pa·s is preferred, more preferably 1 to 75 Pa·s, and particularly preferably 5 to 30 Pa·s. By being within the above range, the temperature fluctuation of the viscous material with respect to the temperature fluctuation of the outside air can be further suppressed. The measurement of the viscosity in the present invention is not particularly limited. For example, after stirring the viscous material with a rod made of polytetrafluoroethylene, 2.0 mL of the viscous material is measured, and the viscosity is measured using a Brookfield (model number: DV-2+Pro) in a state where the temperature is set to 25°C by a temperature control device. As the measurement conditions, CPE-41 (3°×R2.4) is used for the cone rotor, the rotation speed is 10 rpm, and the viscosity after 3 minutes is taken as the "viscosity (Pa·s)".

[0023] (Syringe transport set) As shown in Figure 1, the syringe transport equipment set 1 includes a packaging container 100, a surrounding member 200, and a cooling agent 300. The syringe 500 to be transported by the syringe transport equipment set 1 can be placed in the packaging member 210 with the lid 520 attached to the material storage container 510. The details will be explained below.

[0024] (packaging container) The packaging container 100 shown in Figure 1 can be made of known corrugated cardboard or the like. The packaging container 100 can be constructed by joining materials such as recycled paper or pulp with glue or the like. Furthermore, the packaging container 100 can form a closed space for storing viscous materials by keeping the flaps f, which are provided in a continuous manner on both the upper and lower sides in the height direction Z of the side w, closed with adhesive tape or the like.

[0025] (Enclosing member) As shown in Figures 1 and 2, the surrounding member 200 is installed in the containment space Sp of the packaging container 100 and surrounds the syringe 500. In this embodiment, the surrounding member comprises a packaging member 210 capable of packaging at least a portion of the syringe 500, and a cushioning member 250 that mitigates external forces applied to the syringe 500 during transport.

[0026] (Packaging material) The packaging member 210 is used to hold the syringe 500. As shown in Figure 5, the packaging member 210 comprises an insertion portion 220 and a solid portion 230.

[0027] The insertion portion 220 is provided in the solid portion 230 and is configured to allow insertion of the syringe 500 in an upright position. The insertion portion 220 is oriented in the longitudinal direction (height) to match the shape of the syringe 500. The cross-section perpendicular to direction Z) is constructed to be a perfect circle. However, the shape of the insertion part is that of a syringe. As long as it can maintain a value of 500, it is not limited to this and may be composed of other circles or polygons other than perfect circles, such as ellipses.

[0028] The solid portion 230 is provided around the insertion portion 220 and is configured to form the insertion portion 220. As shown in Figure 6, the solid portion 230 is configured to extend from the first end 231 where the insertion portion 220 is located to the second end 232 on the opposite side of the first end 231 in the direction in which the viscous material is inserted.

[0029] The solid section 230 is constructed to include uncrosslinked foamed polyethylene. The coefficient of linear expansion of the uncrosslinked foamed polyethylene constituting the solid section 230 is 0.1 to 10 × 10 -4 The temperature is cm / cm·℃, preferably 1 to 7 × 10 -4 It can be expressed as cm / cm·℃.

[0030] In this embodiment, the solid portion 230 is configured in layers such that, as shown in Figure 5, a first layer 233, a second layer 234, and a third layer 235 are provided in order in the insertion direction (height direction Z) for inserting the syringe 500. However, the number of layers is not limited to this, and a single layer may be used as long as an insertion portion can be formed.

[0031] As shown in Figure 6, the solid portion 230 is configured such that the second end portion 232 has a flat surface to facilitate the installation of the packaging member 210.

[0032] (cushioning material) The buffer member 250 mitigates the external force applied to the syringe 500 during transport. The buffer member 250 is configured to have a thermal conductivity of 0.022 W / m·K or less (JIS A9521). Note that the thermal conductivity is a value in accordance with JIS A9521. The buffer member 250 can be made of building insulation material containing polystyrene containing air bubbles. In this embodiment, the buffer member 250 is configured in a shape similar to a rectangular parallelepiped. However, the specific shape is not limited to a rectangular parallelepiped as long as it is easy to maintain the temperature of the viscous material. The internal volume of the buffer member 250 is, for example, 318 mm × 415 mm × 330 mm.

[0033] By configuring the buffer member 250 as described above, it can be made lighter than the vacuum insulation material, which can contribute to transporting more viscous material in one go. The weight of the buffer member 250 can be about 4 kg, compared to about 13 kg for the same volume of vacuum insulation material. The weight of one buffer member 250 can be set to approximately 760 g, for example. The vacuum insulation material described above can be constructed, for example, by wrapping a glass wool core material with a gas barrier film and sealing it in a vacuum.

[0034] (Cooling agent) The cold pack 300 cools the syringe 500 housed in the packaging container 100. As shown in Figures 3 and 4, the cold pack 300 comprises a contents storage container 310, a cap 320, and contents 330. The weight of one cold pack 300 can be approximately 1300g, for example.

[0035] The contents storage container 310 is configured to be installed between the syringe 500 and the cushioning member 250 in the storage space Sp of the packaging container 100. The contents storage container 310 has a storage space capable of accommodating the contents 330.

[0036] The contents storage container 310 is configured in a shape such as a rectangular parallelepiped, for example, so that it can be accommodated in the packaging container 100 in various orientations. That is, the surfaces 311 to 316 of the contents storage container 310 are configured as flat surfaces. However, the shape of the contents storage container 310 is just an example, and the specific shape is not limited to a rectangular parallelepiped as long as it can be accommodated in various orientations.

[0037] The contents storage container 310 is configured such that recesses 317 are provided on the relatively large surfaces 311 and 316 among the six surfaces 311 to 316 shown in Figure 4. Furthermore, the contents storage container 310 is configured such that recesses 318 are provided on a part of the hexahedron so that the cap 320 that closes the lid when the contents 330, which is a refrigerant, are contained in the storage space does not easily protrude from the contents storage container 310. However, if the viscous material to be transported can be maintained at a predetermined temperature, the material storage container does not need to have recesses 317 and 318.

[0038] The material constituting the contents storage container 310 is not particularly limited as long as it does not deform to the point of significantly changing volume during transport, or is difficult to deform. Examples include polyethylene, polypropylene, polyethylene terephthalate, etc. The contents storage container 310 can be either a bag type that is relatively easy to deform when external force is applied, or a hard type that is relatively difficult to deform even when external force is applied and can easily maintain a predetermined shape. However, from the viewpoint of resistance to deformation as described above, it is preferable to adopt the hard type.

[0039] The contents 330 cool the syringe 500 contained in the packaging container 100. The contents 330 are configured to have a melting point of -30°C or lower. The lower limit of the melting point of the contents 330 is not particularly limited, but is preferably -50°C. The contents 330 may be configured to include an aqueous solution of an inorganic salt or the like.

[0040] (Method of transporting syringes) Next, a method for transporting syringe 500 using the syringe transport device set according to this embodiment will be described.

[0041] First, prepare a packaging container 100 such as a cardboard box, and secure one side of the flap of the packaging container 100 (the lower side w) by attaching adhesive tape such as packing tape.

[0042] Next, a cushioning member 250 is placed inside the side w of the packaging container 100. The cushioning member 250 can be placed close to the side w so as to surround the sides of the syringe 500 and the packaging member 210 to be contained.

[0043] Once the cushioning member 250 is placed laterally within the internal space of the packaging container 100, the contents, namely the syringe 500 and the packaging member 210, are positioned approximately in the center of the packaging container 100 in the planar directions X and Y. The syringe 500 and the packaging member 210 can be positioned with a gap formed between them and the cushioning member 250 in the first direction X or the second direction Y.

[0044] After placing the syringe 500 and packaging material 210 in the internal space (storage space) of the packaging container 100, the coolant 300 is placed between the buffer material 250 and the syringe 500 and packaging material 210. By placing the buffer material 250 and the coolant 300 between the contents, the syringe 500 and the packaging material 210, the syringe 500 can be transported while cooled to a degree that prevents supercooling.

[0045] Next, the flap f on the opposite side of the bottom of the packaging container 100 (the upper side of the side w) is closed with adhesive tape or the like, and the container is transported towards its destination.

[0046] (How to use packaging materials) Next, the method of using the packaging member 210 will be described. The packaging member 210 is removed from the internal space of the packaging container 100, and with the syringe 500 inserted into the insertion part 220, the container is thawed from -40°C to room temperature. This allows the temperature of the viscous material filled in the syringe 500 to change relatively slowly to room temperature, making the viscous material usable.

[0047] As described above, the syringe transport device set 1 according to this embodiment comprises a surrounding member 200 and a cold storage agent 300. The surrounding member 200 is installed in the containment space Sp of the packaging container 100 and surrounds the syringe 500 which is equipped with a material storage container 510 for containing a viscous material. The surrounding member 200 is equipped with a cushioning member 250 that mitigates external forces applied to the syringe 500 during transport.

[0048] The refrigerant 300 is installable between the syringe 500 and the buffer member 250 in the containment space Sp, and comprises a contents 330 for keeping the syringe 500 cool, and a contents storage container 310 for containing the contents 330. The buffer member 250 has a thermal conductivity of 0.022 W / m·K or less, and the contents 330 have a melting point of -30 degrees or less.

[0049] As described above, transporting viscous materials with dry ice in the transport container results in supercooling of the viscous material. On the other hand, using vacuum insulation material in the transport container makes it relatively heavy, reducing the amount of viscous material that can be transported at one time. In contrast, by configuring the system as described above, it is possible to prevent or suppress supercooling of the viscous material using materials other than vacuum insulation material. Furthermore, by transporting the viscous material using syringe transport equipment set 1, it is possible to suppress temperature fluctuations of the viscous material in response to temperature fluctuations of the outside air.

[0050] Furthermore, the contents storage container 310 is configured such that its surfaces 311 to 316 are flat. As a result, the cooling agent 300 can be placed in the packaging container 100 in various orientations, reducing the constraints imposed by placing the cooling agent 300 in the packaging container 100 and making it easier to transport the syringe 500.

[0051] Furthermore, in the transport method using the syringe transport equipment set 1, the syringe 500 is placed in the storage space Sp of the packaging container 100, and the cooling agent 300 is placed in the storage space Sp so as to surround the syringe 500. Then, the cushioning member 250 is placed in the storage space Sp so as to surround the syringe 500 via the cooling agent 300.

[0052] By configuring it in this way, it is possible to prevent or suppress changes in the product performance of the viscous material contained in syringe 500 due to supercooling during transport, and to prevent crystallization, separation, and sedimentation of the viscous material due to supercooling.

[0053] Furthermore, the packaging member 210 includes an insertion portion 220 and a solid portion 230. The insertion portion 220 is configured to allow insertion of the syringe 500 in an upright position. The solid portion 230 is provided around the insertion portion 220 and is configured to form the insertion portion 220.

[0054] The solid portion 230 is formed from a first end 231 on the side where the insertion portion 220 is located to a second end 232 on the opposite side of the first end 231, in the direction in which the viscous material is inserted into the insertion portion 220. The solid portion 230 is configured to contain non-crosslinked foamed polyethylene.

[0055] This configuration prevents a rapid temperature rise in the viscous material when thawing the viscous material contained in the syringe 500. Furthermore, it suppresses the formation of air bubbles at the interface between the syringe 500 and the viscous material, and mitigates shocks during transport.

[0056] Furthermore, the solid portion 230 is constructed in layers in the direction in which the syringe 500 is inserted into the insertion portion 220. As a result, the packaging material can be made into a shape suitable for any size container, eliminating the need for a mold, and thus improving or making the manufacturability of the packaging material 210 better.

[0057] Furthermore, the solid portion 230 is configured to have a flat surface at the second end portion 232. This configuration allows the viscous material to be transported while the packaging member 210 is stably placed on the loading surface during transport.

[0058] Furthermore, when using the packaging member 210, the syringe 500 is configured to thaw from -40°C to room temperature while inserted into the insertion portion 220 of the packaging member 210. This configuration prevents a rapid temperature rise of the viscous material contained in the syringe 500 and prevents or suppresses the formation of air bubbles at the interface between the syringe 500 and the resin.

[0059] (Experiment 1) The following describes an experiment conducted on the transport of viscous materials. Figure 7 is a graph showing the temperature change of the viscous material in response to the change in ambient temperature over time when a syringe containing the viscous material was transported using the transport equipment sets described in the Examples and Comparative Examples in Experiment 1.

[0060] In Experiment 1, as a comparative example, polystyrene foam, dry ice, and a viscous material contained in a syringe (the object to be transported) were placed in a cardboard packaging container. This packaging container was then placed in a constant temperature bath for 140 hours, with the ambient temperature set according to the program as shown in Figure 7. The melting point of dry ice is -56.6°C. One polystyrene foam unit with external dimensions of 370mm x 496mm x 437mm and a thermal conductivity of 0.04 W / m·K was used. Fourteen pieces of dry ice, each weighing 500g, were used. The syringe used was a polypropylene syringe manufactured by Musashi Engineering Co., Ltd., with a capacity of 70cc, a total length of 223.7mm, an outer diameter of φ26.5mm, and a flange outer diameter of 45 x 30mm.

[0061] Furthermore, the transport equipment set according to the embodiment includes expanded polystyrene (corresponding to a cushioning material, with good heat conductivity). The ratio is 0.022 W / m·K, and the refrigerant and the viscous material contained in the syringe to be transported. The coolant was placed in a cardboard packaging container, and the container was placed in a constant temperature bath for 140 hours. The melting point of the contents of the coolant is -30°C. The viscous material used was epoxy resin.

[0062] The viscous material contained in the syringe was placed in a constant temperature bath for 140 hours, and its temperature was measured to confirm whether the measured temperature affected the properties of the viscous material or whether it could be maintained within the range of -40°C to -20°C, which is difficult to achieve. The experimental results for the examples and comparative examples are shown in Figure 7.

[0063] In Figure 7, the top line at a temperature of 140°C represents ambient air (warm), the second line represents the comparative example, and the third line represents the example. As can be seen from the graph, in the comparative example, the temperature remained below -40°C for 60 hours from the start, a phenomenon known as supercooling, and after 120 hours, the temperature rose above -20°C.

[0064] In contrast, it was confirmed that the temperature could be maintained between -20°C and -40°C throughout the process under the specifications of the example. In other words, while the specifications of the comparative example are likely to affect the product performance of the viscous material during transport, it was confirmed that the specifications of the example are likely to allow transport without affecting the product performance of the viscous material. Furthermore, since the cushioning material in the example can prevent supercooling even with a vacuum insulation material, it is considered that its thermal conductivity can preferably be 0.002 (more preferably 0.01) W / m·K or higher, which is similar to the thermal conductivity of the vacuum insulation material.

[0065] (Experiment 2) Next, we will explain the temperature changes observed during the thawing of viscous materials using packaging materials.

[0066] In Experiment 2, we investigated the temperature change of a viscous material when it was thawed using two types of packaging materials. The viscous material used in the experiment was epoxy resin, and the syringe specifications were as follows: Musashi Engineering Co., Ltd., capacity 70cc, total length 223.7mm, outer diameter φ26.5mm, and outer dimensions of the insertion part 45mm x 30mm.

[0067] The packaging material used in the comparative example is configured as shown in Figure 5, with dimensions of 120mm x 220mm x 220mm (length x width x height), capable of holding 10 syringes, and is a hollow paper packaging material. On the other hand, the packaging material used in the example has dimensions of 120mm x 220mm x 220mm (length x width x height), can hold 10 syringes, and is a solid packaging material formed by stacking non-crosslinked polyethylene (Suntech Foam Q35) with three layers formed in the height direction.

[0068] In Experiment 2, ten syringes were attached to the packaging materials of the comparative example and the example, and the temperature change of the viscous material was observed when the ambient temperature was changed from -40°C to 20°C, which corresponds to room temperature. The temperature was measured using a data logger in a constant temperature bath set to 20°C, with a thermocouple attached to the center of the syringe in the height direction. In this experiment, the viscous material was thawed in the packaging materials of the example and comparative example, and it was checked whether the bead formed by the applied viscous material when applied from a dispenser was continuous. This is because if air bubbles are generated during thawing, it is thought that the bead cannot be applied continuously when applied from a dispenser.

[0069] The experimental results confirmed the temperature changes in the comparative example and the example as described above, and visually checked whether air bubbles were generated in the viscous material such as syringes while the viscous material was contained in the syringes. In addition, the thawed viscous material was applied using the packaging materials of the example and comparative example, and the presence or absence of a broken bead shape was visually checked. The above test is also called a discharge test, and by blowing air directly into the syringe to discharge the entire amount of viscous material, air bubbles inside the viscous material that cannot be seen by visual inspection of the external appearance were checked. Below, Figure 8 shows graphs of the temperature changes when syringes containing viscous material in the packaging materials of the comparative example and the example were thawed from -40°C to room temperature. In Figure 8, the data located at the top corresponds to the comparative example, and the data located at the bottom corresponds to the example.

[0070] It was confirmed that the paper packaging material in the comparative example exhibited a more rapid temperature change from -40°C to room temperature compared to the packaging material in the example. Furthermore, while air bubbles were visually observed inside the syringe during the dispensing test for the packaging material in the comparative example, no air bubbles were observed inside the syringe for the packaging material in the example.

[0071] Furthermore, when applying the viscous material from a dispenser, the specifications of the comparative example resulted in breaks in the application of the viscous material bead, whereas the specifications of the example did not result in breaks in the application of the viscous material, and it was confirmed that the bead was continuous. From the above, it was confirmed that the specifications of the example allowed the thawed viscous material to be attached to a dispenser and maintained in a state where it could be used (dispensed).

[0072] This application is based on Japanese Patent Application No. 2021-069242, filed on April 15, 2021, and its disclosures are incorporated as a whole by reference. [Explanation of Symbols]
