Description

Syringe transport set, syringe transport method, packaging material, and method of using packaging material

[0001] The present invention relates to a syringe transport set, a syringe transport method, a packaging member, and a method of using the packaging member.

[0002] There are various types of viscous materials, including, for example, one-component curing resins and two-component curing resins, etc. Among these, some one-component curing resins harden even at room temperature, and some need to be kept at temperatures below 0°C during the manufacturing, transportation, storage, etc.

[0003] One technique for maintaining the temperature of one-component curing resins at or below 0°C during transport, etc., is to place dry ice inside a container made of insulating material (see Patent Document 1). Another technique for keeping contents warm (cold) is to provide an inner box, an outer box, and a vacuum insulating material placed between the inner and outer boxes and covered with a film, with the outer box and the vacuum insulating material tightly secured together via a flexible member with double-sided adhesive between them (see Patent Document 2). Here, vacuum insulating material refers to insulating material surrounded by a vacuum.

[0004] Patent No. 4503457 Specification No. 01-20631

[0005] The present inventors have conducted extensive research, focusing on the fact that when a viscous material is transported in a container filled with dry ice as in Patent Document 1, the viscous material becomes supercooled, which affects product performance. Specifically, there is a risk that the viscous material will crystallize due to supercooling, or that separation or sedimentation will occur when the supercooled viscous material is thawed. Furthermore, the present inventors are concerned that when a vacuum insulation material is used in a container for transport as in Patent Document 2, the weight of the transport container will be relatively heavy, resulting in a relatively small amount of viscous material that can be transported at one time.

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

[0007] A syringe transport set according to one aspect of the present invention, which solves the above-mentioned problems, includes an enclosing member and a refrigerant. The enclosing member is installed in the storage space of the packaging container and encloses a syringe equipped with a material storage container that contains a viscous material, and includes a buffer member that absorbs external forces applied to the syringe during transportation. The refrigerant can be installed between the syringe and the enclosing member in the storage space and includes a content that keeps the syringe cool and a content storage container that stores the content. The buffer member has a thermal conductivity of 0.022 W / m·K or less, and the content has a melting point of -30°C or less.

[0008] A syringe transport method according to one aspect of the present invention includes placing a syringe in the storage space of the packaging container, placing a refrigerant in the storage space so as to surround the syringe, and placing a surrounding member in the storage space so as to surround the syringe via the refrigerant.

[0009] Another aspect of the present invention is a packaging member for holding the syringe, and a method for using the packaging member.

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments shown here are merely examples for embodying the technical concept of the present invention and are not intended to limit the present invention. Furthermore, all other embodiments, 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 within the scope and spirit of the present invention, as well as within the scope of the claims and their equivalents.

[0012] Furthermore, for the convenience of illustration and ease of understanding, the drawings attached to this specification may be represented schematically with the scale, aspect ratio, shape, etc. appropriately changed from the actual product, 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, but unless otherwise specified, these are used for convenience and do not stipulate any particular order.

[0014] In the following, a coordinate system is used in the drawings and explanations. X and Y are planar directions in which the packaging material 210, the buffer material 250, and the refrigerant 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 packaging container 100 and the packaging material 210, and is referred to as the height direction Z.

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

[0016] The material storage container 510 is configured to have a semi-closed space Sc for containing the viscous material. The material storage container 510 has an opening 511 that can discharge the viscous material from the semi-closed space Sc, as shown in Fig. 6. The material storage container 510 can have a plunger 530 at its middle in the height direction Z, as shown in Fig. 6.

[0017] The plunger 530 is movable in the height direction Z, and thus can move the viscous material filled in the semi-closed space Sc in a sealed state toward the opening 511. In this embodiment, the plunger 530 is provided at the center of the material storage container 510 in the height direction Z, 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 shape at the tip of the substantially cylindrical shape in the height direction Z. However, the specific shape is not limited to the above as long as it can form a semi-closed space for storing the viscous material.

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

[0020] Specific examples of the viscous material transported by the syringe transport device set 1 according to this embodiment include adhesives, sealants, coating agents, conductive adhesives, thermally conductive resins, and flame-retardant resins. Among these, adhesives, sealants, conductive adhesives, and thermally conductive resins are preferred because they can further suppress temperature fluctuations of the viscous material in response to temperature fluctuations in the outside air, and adhesives and conductive adhesives are particularly preferred.

[0021] The components of the viscous material are not particularly limited, but examples thereof include urethane resin, epoxy resin, oxetane resin, (meth)acrylic resin, silicone resin, etc. Among these, epoxy resin, oxetane resin, and (meth)acrylic resin are preferred, and epoxy resin is particularly preferred. By using more preferred components, temperature fluctuations of the viscous material due to temperature fluctuations in the outside air can be further suppressed.

[0022] The viscosity of the viscous material is not particularly limited, but is preferably in the range of 0.1 to 150 Pa·s, more preferably 1 to 75 Pa·s, and particularly preferably 5 to 30 Pa·s. By keeping the viscosity within the above range, temperature fluctuations of the viscous material due to fluctuations in the ambient temperature can be further suppressed. The viscosity measurement in the present invention is not particularly limited, but for example, after stirring with a polytetrafluoroethylene rod, 2.0 mL of the viscous material is measured, and the viscosity is measured using a Brookfield (model number: DV-2+Pro) with the temperature set to 25°C using a temperature controller. The measurement conditions were a CPE-41 (3° x R2.4) cone rotor, a rotation speed of 10 rpm, and the viscosity after 3 minutes was recorded as "viscosity (Pa·s)."

[0023] (Syringe Transport Set) As shown in Fig. 1, the syringe transport set 1 includes a packaging container 100, an enclosing member 200, and a refrigerant 300. The syringe 500 to be transported by the syringe transport set 1 can be placed in the packaging member 210 with the lid 520 attached to the material storage container 510. This will be explained below.

[0024] (Packaging Container) The packaging container 100 shown in Fig. 1 can be made of known cardboard or the like. The packaging container 100 can be made by joining materials such as waste paper or pulp with glue or the like. The packaging container 100 can form a closed space for storing a viscous material by keeping flaps f, which are provided continuously on both the top and bottom of the side surface w in the height direction Z, closed with adhesive tape or the like.

[0025] 1 and 2 , surrounding member 200 is placed in storage space Sp of packaging container 100 and surrounds syringe 500. In this embodiment, the surrounding member includes packaging member 210 that can package at least a portion of syringe 500, and buffer member 250 that buffers external forces applied to syringe 500 during transportation of syringe 500.

[0026] (Packaging Member) The packaging member 210 is used to hold the syringe 500. The packaging member 210 includes an insert portion 220 and a solid portion 230, as shown in FIG.

[0027] Insertion portion 220 is provided in solid portion 230 and is configured so that syringe 500 can be inserted in an upright position. Insertion portion 220 has a cross section perpendicular to the longitudinal direction (height direction Z) that is a perfect circle to match the shape of syringe 500. However, the shape of the insertion portion is not limited to this as long as it can hold syringe 500, and it may be configured as a circle other than a perfect circle, such as an ellipse, or a polygon.

[0028] The solid portion 230 is provided around the insertion portion 220 and is configured to form the insertion portion 220. The solid portion 230 is configured to be formed from a first end 231 where the insertion portion 220 is located to a second end 232 opposite the first end 231 in the direction in which the viscous material is inserted, as shown in FIG.

[0029] The solid portion 230 is configured to contain non-crosslinked foamed polyethylene. The linear expansion coefficient of the non-crosslinked foamed polyethylene that constitutes the solid portion 230 is 0.1 to 10×10 －４ cm / cm °C, preferably 1 to 7 × 10 －４ It can be expressed as cm / cm·°C.

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

[0031] As shown in FIG. 6, the solid portion 230 is configured so that the second end 232 is a flat surface so that the packaging member 210 can be easily placed thereon.

[0032] (Buffering Member) The buffering member 250 buffers external forces applied to the syringe 500 during transportation. The buffering member 250 is configured to have a thermal conductivity of 0.022 W / m·K or less (JIS A9521). The thermal conductivity is a value conforming to JIS A9521. The buffering member 250 can be made of a construction insulation material, such as polystyrene containing bubbles. In this embodiment, the buffering member 250 is configured in a substantially rectangular parallelepiped shape. 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 buffering member 250 is, for example, 318 mm x 415 mm x 330 mm.

[0033] By configuring the buffer member 250 as described above, it can be made lighter than vacuum insulation material, which can contribute to increasing the amount of viscous material that can be transported at one time. The weight of the buffer member 250 can be made approximately 4 kg, compared to approximately 13 kg for a vacuum insulation material of the same volume. As an example, the weight of each buffer member 250 can be made approximately 760 g. The above-mentioned vacuum insulation material can be configured, for example, by wrapping a glass wool core material in a gas barrier film and creating a vacuum to seal it.

[0034] (Cooling agent) The cooling agent 300 cools the syringe 500 contained in the packaging container 100. As shown in Figures 3 and 4, the cooling agent 300 includes a content storage container 310, a cap 320, and a content 330. The weight of each cooling agent 300 can be, for example, approximately 1,300 g.

[0035] The content storage container 310 is configured so as to be able to be placed between the syringe 500 and the buffer member 250 in the storage space Sp of the packaging container 100. The content storage container 310 has a storage space capable of storing the content 330.

[0036] The content storage container 310 is configured in a shape such as a rectangular parallelepiped, for example, so that it can be stored in the packaging container 100 in various positions. In other words, surfaces 311 to 316 of the content storage container 310 are configured as flat surfaces. However, the shape of the content storage container 310 is only an example, and the specific shape is not limited to a rectangular parallelepiped as long as it can be stored in various positions.

[0037] Content storage container 310 is configured to have recesses 317 on faces 311 and 316, which have relatively large areas among the six faces 311 to 316 shown in Figure 4. Furthermore, content storage container 310 is configured to have recesses 318 on part of the hexahedron so that cap 320, which covers content 330, a refrigerant, is less likely to protrude from content storage container 310 when the content storage container 310 contains content 330, which is a refrigerant, in the storage space. However, recesses 317 and 318 do not have to be provided in the material storage container as long as the viscous material to be transported can be maintained at a predetermined temperature.

[0038] The material constituting the content storage container 310 is not particularly limited as long as it does not deform so much that the volume changes significantly during transportation or is difficult to deform, and examples include polyethylene, polypropylene, polyethylene terephthalate, etc. The content storage container 310 may be either a bag type that is relatively easily deformed when an external force is applied, or a hard type that is relatively difficult to deform even when an external force is applied and is easy to maintain a predetermined shape, but it is preferable to use a hard type from the viewpoint of the above-mentioned difficulty to deform.

[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. There is no particular limitation on the lower limit of the melting point of the contents 330, but it is preferably −50° C. The contents 330 can be configured to contain an aqueous solution of an inorganic salt or the like.

[0040] (Syringe Transporting Method) Next, a method for transporting the syringe 500 using the syringe transporting tool set according to this embodiment will be described.

[0041] First, a packing container 100 such as a cardboard box is prepared, and one of the flap portions of the packing container 100 (the lower side of the side w) is held closed by sticking adhesive tape such as packing tape.

[0042] Next, the buffer member 250 is placed inside the side surface w of the packaging container 100. The buffer member 250 can be installed close to the side surface w to the extent that it can surround the sides of the syringe 500 and the packaging member 210 to be housed therein.

[0043] After buffer member 250 is placed on the side of the internal space of packaging container 100, syringe 500 and packaging member 210, which are the contents, are placed approximately in the center in the planar direction XY of packaging container 100. Syringe 500 and packaging member 210 can be placed with a gap formed between them and buffer member 250 in the first direction X or the second direction Y.

[0044] After syringe 500 and packaging member 210 are placed in the internal space (storage space) of packaging container 100, refrigerant 300 is accommodated between buffer member 250 and syringe 500 / packaging member 210. By arranging buffer member 250 and refrigerant 300 between syringe 500, which is the content, and packaging member 210, syringe 500 can be transported in a cooled state that is not supercooled.

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

[0046] (Method of Using the Packaging Member) Next, a 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 the container is thawed from −40° C. to room temperature with the syringe 500 inserted into the insertion portion 220. 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 tool set 1 according to this embodiment includes the surrounding member 200 and the refrigerant 300. The surrounding member 200 is placed in the storage space Sp of the packaging container 100 and surrounds the syringe 500 equipped with the material storage container 510 that stores the viscous material. The surrounding member 200 includes a buffer member 250 that absorbs external forces applied to the syringe 500 during transportation.

[0048] The ice storage agent 300 can be placed between the syringe 500 and the buffer member 250 in the storage space Sp, and includes a content 330 that keeps the syringe 500 cool, and a content storage container 310 that stores the content 330. The buffer member 250 has a thermal conductivity of 0.022 W / m·K or less, and the content 330 has a melting point of −30° C. or less.

[0049] As described above, if dry ice is placed in the transport container to transport a viscous material, the viscous material will be supercooled. On the other hand, if vacuum insulation is used in the transport container, the weight will be relatively heavy, and the amount of viscous material that can be transported at one time will be relatively small. In contrast, by using the above-described configuration, it is possible to prevent or suppress supercooling of the viscous material using a material other than vacuum insulation. Furthermore, by transporting the viscous material using the syringe transport device set 1, it is possible to suppress temperature fluctuations of the viscous material due to fluctuations in the outside air temperature.

[0050] Furthermore, content storage container 310 is configured so that surfaces 311 to 316 are flat. Therefore, ice storage agent 300 can be placed in various positions relative to packaging container 100, and restrictions imposed by placing ice storage agent 300 in packaging container 100 are reduced, making it easier to transport syringe 500.

[0051] In addition, in the transportation method using syringe transportation tool set 1, syringe 500 is placed in storage space Sp of packaging container 100, and refrigerant 300 is placed in storage space Sp so as to surround syringe 500. Then, buffer member 250 is placed in storage space Sp so as to surround syringe 500 via refrigerant 300.

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

[0053] Packaging member 210 also includes insertion portion 220 and solid portion 230. Insertion portion 220 is configured to allow syringe 500 to be inserted in an upright position. Solid portion 230 is provided around insertion portion 220 and is configured to form insertion portion 220.

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

[0055] This configuration can prevent a sudden rise in temperature of the viscous material when thawing the viscous material contained in the syringe 500. It also prevents air bubbles from entering the interface between the syringe 500 and the viscous material, and can mitigate shocks during transportation.

[0056] Furthermore, solid portion 230 is configured in layers in the direction in which syringe 500 is inserted into insertion portion 220. This allows the packaging member to be shaped to fit any size of container, eliminating the need for a mold, and improving or enhancing the manufacturability of packaging member 210.

[0057] Furthermore, the solid portion 230 is configured to have a flat surface at the second end 232. By configuring it in this manner, the viscous material can be transported while the packaging member 210 is stably placed on a placement surface during transportation.

[0058] Furthermore, packaging member 210 is configured so that syringe 500 is thawed from −40° C. to room temperature while syringe 500 is inserted into insertion portion 220 of packaging member 210. This configuration prevents a sudden increase in temperature of the viscous material contained in syringe 500, and can prevent or suppress the intrusion of air bubbles at the interface between syringe 500 and the resin.

[0059] (Experiment 1) An experiment on the transportation of a viscous material was conducted as follows: Fig. 7 is a graph showing the temperature change of the viscous material over time when syringes containing the viscous material were transported using the transportation equipment sets according to the example and the comparative example in Experiment 1.

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

[0061] The transportation set according to the example was made by placing polystyrene foam (corresponding to a buffer material, with a thermal conductivity of 0.022 W / m·K), a refrigerant, and a syringe containing a viscous material to be transported in a cardboard packaging container, and then placing the packaging container in a constant temperature bath for 140 hours. The melting point of the contents of the refrigerant was -30°C. The viscous material used was epoxy resin.

[0062] The viscous material contained in the syringe was placed in a thermostatic chamber for 140 hours, and the temperature was measured to confirm whether the measured temperature was maintained within the range of -40°C to -20°C, which does not affect the properties of the viscous material or is unlikely to do so. The experimental results of the example and comparative example are shown in Figure 7.

[0063] 7, the first line from the top at a temperature of 140°C corresponds to outside air (warm), the second line from the top corresponds to the comparative example, and the third line from the top corresponds to the example. As can be seen from the graph, in the comparative example, the temperature fell below -40°C within 60 hours from the start, which is known as supercooling, and it was confirmed that the temperature rose above -20°C after 120 hours.

[0064] In contrast, it was confirmed that the specifications according to the examples were able to maintain a temperature between -20°C and -40°C throughout. In other words, it was confirmed that the specifications according to the comparative examples were likely to affect the product performance of the viscous material during transportation, while the specifications according to the examples were likely to allow transportation without affecting the product performance of the viscous material. Note that, because the buffer material according to the examples can prevent supercooling even in vacuum insulation materials, its thermal conductivity is thought to be effective even at 0.002 (more preferably 0.01) W / m·K or more, which is approximately the same as the thermal conductivity of vacuum insulation materials.

[0065] (Experiment 2) Next, the temperature change during thawing of a viscous material using a packaging material was confirmed and will be explained.

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

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

[0068] In Experiment 2, ten syringes were set in the packaging materials according to the Comparative Example and the Example, and the temperature change of the viscous material was confirmed 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 thermostatic chamber set at 20°C, with a thermocouple attached to the center of the syringe height. In this experiment, the viscous material was thawed in the packaging materials according to the Example and the Comparative Example, and it was confirmed whether the bead formed by the viscous material when applied from the dispenser was continuous. This is because it is thought that if air bubbles are generated during thawing, a continuous bead cannot be applied when applied from the dispenser.

[0069] The experimental results were obtained by confirming the temperature change of the comparative example and the example as described above, and visually checking whether air bubbles had formed in the viscous material in the syringe or other containers containing the viscous material. Furthermore, the viscous material thawed using the packaging materials of the example and comparative example was applied using a dispenser with a needle (30G) tip, and visually inspected to see if the formed bead shape was broken. This test, also known as a discharge test, involves blowing air directly into the syringe to discharge the entire amount of viscous material, thereby checking for air bubbles inside the viscous material that cannot be detected visually by external inspection. Figure 8 shows a graph of temperature change when syringes containing viscous material in the packaging materials of the comparative example and the example were thawed from -40°C to room temperature. The data at the top of Figure 8 correspond to the comparative example, and the data at the bottom correspond to the example.

[0070] It was confirmed that the paper packaging member according to the comparative example had a more rapid temperature change from -40°C to room temperature than the packaging member according to the example. Furthermore, air bubbles were visually confirmed inside the syringe in the packaging member according to the comparative example during the discharge test, whereas no air bubbles were confirmed inside the syringe in the packaging member according to the example.

[0071] Furthermore, when applying the viscous material from the dispenser, the specifications for the comparative example caused the bead of viscous material to break off, whereas the specifications for the example did not cause the viscous material to break off and the bead was continuous. From the above, it was confirmed that the thawed viscous material according to the specifications for the example can be attached to a dispenser or the like and maintained in a usable (dischargeable) state.

[0072] This application is based on Japanese Patent Application No. 2021-069242 filed on April 15, 2021, the disclosure of which is incorporated by reference in its entirety.
