Accommodation device for a freezing target

Description

61 ACCOMMODATION DEVICE FOR A FREEZING TARGET Field

[001] The present invention relates to an accommodation apparatus for a freezing target. Fundamentals

[002] Some medicines, specimens, various samples and the like are stored and transported in a frozen state (hereinafter, “freezing target”). For example, a freezing container is used to store and transport the freezing target.

[003] A freezing container is a thermally insulated container that includes a storage space for storing a freezing target and a refrigerant chamber for storing a refrigerant, such as liquid nitrogen. For example, the storage space extends downward from an opening provided at the upper end of the freezing container, and the refrigerant chamber is provided around the storage space. In the freezing container, it is necessary to ensure sufficient refrigerant chamber volume, and therefore the volume of the storage space must be less than the apparent size of the freezing container.

[004] In view of these circumstances, a device was proposed to store a large number of freezing targets in a limited volume storage space.

[005] For example, a sample storage support (an accommodation apparatus) described in Patent Literature 1 includes an accommodation unit consisting of a metal box for accommodating a sample or similar object, and a suspension element (an axle element) consisting of a substantially L-shaped metal axle whose lower end is attached to the accommodation unit and having a Petition 870260082298, dated 08 / 14 / 2026, page 11 / 140 / 61 hook provided at the upper end.

[006] In Patent Literature 1, four types of sample storage supports are prepared having different lengths of suspension elements. Using the four types of sample storage supports, four accommodation units can be stored in a storage space at intervals along the vertical direction. In addition, a plurality of sets of the four accommodation units can be stored at intervals along the circumferential direction. Furthermore, a storage unit selected from a plurality of storage units stored in the storage space can be removed while the other storage units are stored.

[007] An accommodation apparatus described in the Patent Literature includes a metal receptacle (an accommodation unit for accommodating a sample or the like) having a cylindrical shape with an open top end, and a suspension hook (an axle element) consisting of a metal shaft whose lower end portion is joined to the outer peripheral surface of the receptacle and having a hook provided at the upper end.

[008] In Patent Literature 2, two types of accommodation apparatuses having different lengths of suspension hooks are prepared. Using the two types of accommodation apparatuses, two receptacles can be stored in a storage space at intervals along the vertical direction. Furthermore, a plurality of sets of the two receptacles can be stored at intervals along the circumferential direction. In addition, a receptacle selected from among the receptacles stored in the storage space can be removed while the other receptacles are stored.

[009] In the accommodation devices described in the Literature of Petition 870260082298, dated 08 / 14 / 2026, page 12 / 140 / 61 Patents 1 and 2, since the accommodation units can be stored in the storage space to be spaced from each other in the vertical direction, a large number of freezing targets can be stored in the storage space.

[0010] However, in order to remove a specific accommodation unit from among the accommodation units, it was necessary to ensure a passage for removal in such a way that the other accommodation units left in the storage space did not obstruct the removal of the specific accommodation unit.

[0011] Specifically, to remove a lower accommodation unit, the lower accommodation unit is moved laterally once and then pulled upwards. Therefore, it was necessary to ensure a passage (a space or a dead space) for such movement in advance. Consequently, a problem arose that, as a dead space corresponding to such a passage is formed in the storage space, a space to store the freezing target is reduced. Citation List Patent Literature

[0046] The embodiments of the present invention will be described below in detail with reference to the drawings. The constituent elements, types, combinations, shapes and relative arrangements described in the embodiments are merely illustrative examples and are not intended to limit the scope of the present invention to them alone, unless otherwise specified.<Esboço da primeira modalidade>

[0047] Figure 1 is a front view of an accommodation device. Petition 870260082298, dated 08 / 14 / 2026, p. 17 / 140 / 61 100A according to a first embodiment and a freezing container 300. First, the sketch of the accommodation apparatus 100A according to the first embodiment is described with reference to Figure 1.

[0048] Accommodation apparatus 100A includes a group of accommodation units 1 including accommodation units 10 to 40 respectively accommodating freezing targets 91 to 94 constituting a freezing target group 90 such that freezing targets 91 to 94 can be freely removed. For example, the group of accommodation units 1 includes the first accommodation unit 10 placed on a pedestal 200, the second accommodation unit 20 arranged above the first accommodation unit 10, the third accommodation unit 30 arranged above the second accommodation unit 20, and the fourth accommodation unit 40 arranged above the third accommodation unit 30. Here, “arranged above” means that accommodation units 10 to 40 are arranged in a state where they can be pulled upwards collectively.Therefore, “arranged above” includes a state in which the upper accommodation unit 20, 30 or 40 is placed directly above the lower accommodation unit 10, 20 or 30, and a state in which the upper and lower accommodation units are arranged to be spaced from each other in the vertical direction (for example, a state in which another element, such as a damping element, is interposed between the upper and lower accommodation units).

[0049] Accommodation units 10 to 40 accommodate freezing targets 91 to 94, respectively, and are stored in a storage space SP323 provided within freezing container 300. In the present embodiment, freezing targets 91 to 94 are a plurality of vials, each stored in a box, for example, but are not limited to this.

[0050] The 100A accommodation device includes a shaft element. Petition 870260082298, dated 08 / 14 / 2026, page 18 / 140 / 61 80A to be coupled to each of the accommodation units 10 to 40 individually and in a removable manner. In the accommodation units 10 to 40 (in this example, at the lower front ends), female screw elements (coupled portions) 16a to 46a are provided, respectively, to which a male screw portion 82 (a coupling portion) provided in the shaft element 80A (in this example, the lower end) must be coupled.

[0051] Specifically, the first female screw element 16a is provided at the lower front end of the first housing unit 10, and the second female screw element 26a is provided at the lower front end of the second housing unit 20. Similarly, the third female screw element 36a is provided at the lower front end of the third housing unit 30, and the fourth female screw element 46a is provided at the lower front end of the fourth housing unit 40.

[0052] Female screw elements 16a to 46a are provided at predetermined intervals along the right-left direction (circumferential direction) as seen from above.

[0053] Each of the female screw elements 16a to 46a is configured in such a way that their positions in the right-left direction and in the circumferential direction do not coincide (interfere) with each other. Therefore, even in a state where the accommodation units 10 to 40 are stacked, as illustrated in Figure 1, each of the female screw elements 16a to 46a can be coupled to the male screw portion 82 of the shaft element 80A individually and selectively. Therefore, an insertion opening (described later) through which the shaft element 80A is inserted and pulled upwards is provided above each of the female screw elements 16a to 46a in each of the accommodation units 10 to 40.

[0054] In a case of withdrawal of each of the units of Petition 870260082298, dated 08 / 14 / 2026, page 19 / 140 / 61 accommodation 10 to 40 (each of the freezing targets 91 to 94) stored in storage space SP323, the male screw portion 82 of shaft element 80A is coupled to the female screw element 16a, 26a, 36a or 46a of the accommodation unit 10, 20, 30 or 40 to be removed and, after that, shaft element 80A is moved upwards. With the upward movement of shaft element 80A, the corresponding accommodation unit 10, 20, 30 or 40 is moved upwards and removed from storage space SP323.

[0055] As accommodation units 10 to 40 are arranged to be stacked, only the topmost accommodation unit 40 can be removed on its own. However, accommodation units 10, 20 and 30 located below cannot be removed on their own.

[0056] For example, as indicated by the solid line in Figure 1, when the male screw portion 82 of the shaft element 80A is coupled to the first female screw element 16a and then the shaft element 80A is pulled up, the four accommodation units 10 to 40 can be removed collectively. As indicated by the dashed line in Figure 1, when the male screw portion 82 is coupled to the second female screw element 26a and then the shaft element 80A is pulled up, the three accommodation units 20 to 40 can be removed collectively while the first accommodation unit 10 is left in the storage space SP323.As indicated by the long and short dashed line in Figure 1, when the male screw portion 82 is coupled to the third female screw element 36a and then the shaft element 80A is pulled upwards, the two accommodation units 30 and 40 can be removed while the two accommodation units 10 and 20 are left in the storage space SP323. As indicated by the long and double short dashed line in Figure 1, when the male screw portion 82 is coupled to the fourth female screw element 46a and then the element... Petition 870260082298, dated 08 / 14 / 2026, page 20 / 140 / 61 of shaft 80A is pulled up, only the fourth accommodation unit 40 can be removed, while the three accommodation units 10 to 30 are left in storage space SP323.

[0057] As described above, by selecting the female screw element 16a, 26a, 36a or 46a to which the male screw portion 82 of the shaft element 80A is coupled, it is possible to select the accommodation unit 10, 20, 30 or 40 to be removed from the storage space SP323.

[0058] In the accommodation apparatus 100A according to the first embodiment, since the accommodation units 20 to 40 above the selected accommodation units 10 to 30 can also be pulled up collectively, it is not necessary to provide a passage to allow the selected accommodation units 10 to 30 to pass through them above the selected accommodation units 10 to 30. Consequently, the size of each of the accommodation units 10 to 40 stored in the storage space SP323 can be maximized according to the size of the storage space SP323 or similar, so that the quantity of freezing targets 91 to 94 that can be stored can be increased compared with a use case of the conventional accommodation apparatus described in Patent Literature 1 or 2. <Recipiente de congelamento 300>

[0059] Before the description of the accommodation apparatus 100A according to the first embodiment, the freezing container 300 in which the group of accommodation units 1 of the accommodation apparatus 100A is accommodated is described.

[0060] As illustrated in Figure 1, the freezing container 300 includes a container body 310 having the storage space SP323 within it. The container body 310 has a bottle shape with Petition 870260082298, dated 08 / 14 / 2026, page 21 / 140 / 61 a circular cross-section and a diameter of an upper end part smaller than the diameter of other parts. The container body 310 has a double-walled structure, including an outer perimeter wall 311 and an inner perimeter wall 312. The space between the outer perimeter wall 311 and the inner perimeter wall 312 is sealed and forms a sealed space SP321.

[0061] The sealed space SP321 is decompressed and forms a thermal insulation structure with low heat transfer between the outer perimeter wall 311 and the inner perimeter wall 312.

[0062] An internal space is formed within the inner perimeter wall 312. A partition wall 313 having a square cylindrical shape is provided in the lower half of the internal space. The partition wall 313 divides the lower half of the internal space in a liquid-tight manner into a refrigerant chamber SP322 on the outer perimeter side of the partition wall 313 and the storage space SP323 on the inner perimeter side of the partition wall 313.

[0063] Partition wall 313 is made of a high heat transfer material that can be used even at extremely low temperatures. Although partition wall 313 is formed from a stainless steel plate in the present embodiment, it can be made of another material.

[0064] The SP322 refrigerant chamber is a space in which an LQN refrigerant, such as liquid nitrogen, is stored. A wave dissipating plate 314 extending laterally from the partition wall 313 is provided on the outer peripheral surface of the partition wall 313. The wave dissipating plate 314 is an element to reduce the ripple of the LQN refrigerant during the movement of the freezing container 300 and is provided in multiple stages (e.g., three stages) at intervals along the vertical direction. Petition 870260082298, dated 08 / 14 / 2026, page 22 / 140 / 61

[0065] A refrigerant supply tube 315 for supplying LQN refrigerant from outside the container body 310 is arranged in the refrigerant chamber SP322. The upper part of the refrigerant supply tube 315 is bent to the side, and the distal end of the refrigerant supply tube 315 projects out of an opening portion 316 provided in the upper end part of the container body 310. The protruding part of the refrigerant supply tube 315 is provided with a coupling fitting 315a for coupling to a tube of a refrigerant supply portion (not shown) when LQN refrigerant is supplied to the refrigerant chamber SP322.

[0066] In addition, in refrigerant chamber SP322, a detector 317a of a liquid level gauge 317 is arranged which detects the height of the refrigerant liquid level LQN (a storage quantity of refrigerant LQN) in refrigerant chamber SP322.

[0067] Storage space SP323 is a space in which accommodation unit group 1 is to be stored and is cooled to an extremely low temperature by refrigerant LQN stored in refrigerant chamber SP322. An upper space SP324 is provided between storage space SP323 and the opening portion 316 of freezing container 300. Upper space SP324 is a space into which a lid (not shown) included with freezing container 300 is to fit.

[0068] In storage space SP323, in addition to accommodation unit group 1, pedestal 200 and an SPG liquid absorbent are also stored. Pedestal 200 is an element to prevent contact between each of the accommodation units 10, 20, 30 and 40 and the LQA liquid air and includes a support plate 201 on which the first accommodation unit 10 must be placed. Pedestal 200 will be described later. The SPG liquid absorbent is formed by a porous body that absorbs the LQA liquid air in the SP322 refrigerant chamber. By causing the Petition 870260082298, dated 08 / 14 / 2026, page 23 / 140 / 61 liquid absorbent SPG absorbs liquid air LQA, accommodation unit group 1 is less likely to come into contact with liquid air LQA. <Grupo de unidades de acomodação 1>

[0069] Next, the accommodation unit group 1 (accommodation units 10, 20, 30 and 40) included in the accommodation apparatus 100A is described. Figure 2 is a perspective view of the first accommodation unit 10 located in the first stage (lowest stage), Figure 3 is a perspective view of the second accommodation unit 20 located in the second stage (intermediate stage), Figure 4 is a perspective view of the third accommodation unit 30 located in the third stage (intermediate stage), Figure 5 is a perspective view of the fourth accommodation unit 40 located in the fourth stage (topmost stage), and Figure 6 is a perspective view illustrating the stacked state of the accommodation unit group 1.

[0070] In the following embodiment, the second accommodation unit 20 is placed on the first accommodation unit 10, the third accommodation unit 30 is placed on the second accommodation unit 20, and the fourth accommodation unit 40 is placed on the third accommodation unit 30. However, their configuration is not limited to this configuration. It is sufficient that the accommodation units 10 to 40 are arranged in a state where they can be pulled upwards collectively. Therefore, the accommodation units 10 to 40 can be spaced from each other in the vertical direction with another element, such as a sheet-type damping material, interposed between the accommodation units 10 to 40 located above and below. <Primeira unidade de acomodação 10>

[0071] The first accommodation unit 10 illustrated in Figure 2 is a box-shaped element having a bottom plate 11, a plate of Petition 870260082298, dated 08 / 14 / 2026, page 24 / 140 / 61 top 12, a front plate 13, a rear plate 14 and a right side plate 15. The internal space of the first accommodation unit 10 is a first accommodation space SP10 that accommodates the first freezing target 91 in it (see Figure 1). An opening on the left side is an inlet / outlet OP1 for the first freezing target 91. For each of the plates 11, 12, 13, 14 and 15 that constitute the first accommodation unit 10, a material having resistance to extremely low temperatures is used, for example, a stainless steel plate.

[0072] The front plate 13 has a front plate body 13a provided through the bottom plate 11 and the top plate 12, a lower end portion 13b projecting forward from the lower end edge of the front plate body 13a, and an upper end portion 13c projecting forward from the upper end edge of the front plate body 13a.

[0073] A front end portion 11a of the bottom plate 11 and a front end portion 12a of the top plate 12 project forward from the body of the front plate 13a. The front end portion 11a of the bottom plate 11 and the bottom end portion 13b of the front plate 13 are joined together to form a lower protruding piece 16, and the front end portion 12a of the top plate 12 and the top end portion 13c of the front plate 13 are joined together to form an upper protruding piece 17.

[0074] The first female screw element 16a is provided on the upper surface of the lower protruding part 16 in a position on the right side when viewed from the front.

[0075] The first female screw element 16a is an element having a female screw formed on its inner periphery, the female screw being able to be coupled to the male screw of the shaft element 80A (the male screw portion 82). Petition 870260082298, dated 08 / 14 / 2026, p. 25 / 140 / 61

[0076] The first female screw element 16a of the present embodiment is a nut made of stainless steel and is fixed to the upper surface of the lower protruding part 16 by welding. The method of fixing the first female screw element 16a is not limited to welding, provided that the fixed state can be maintained at extremely low temperatures.

[0077] A first upper insertion opening 17a is provided in the upper protruding part 17 in a position directly above the first female screw element 16a. The first upper insertion opening 17a is provided to have a size that allows a shaft body 81 (the male screw portion 82) of the shaft element 80A to be inserted through it. Therefore, the male screw portion 82 of the shaft body 81 can be coupled to the first female screw element 16a through the first upper insertion opening 17a.

[0078] A pair of first positioning protrusions 17b are provided on the upper surface of the upper protruding part 17 on the left and right sides. The first positioning protrusions 17b are provided to restrict the position of the second accommodation unit 20. As described later, a pair of second positioning voids 26c are provided on a lower protruding part 26 of the second accommodation unit 20, into which the pair of first positioning protrusions 17b fits (see Figure 3).

[0079] The first positioning protrusions 17b are each formed by a stainless steel plate bent into an arc shape (inverted U shape), for example, and are fixed to the upper surface of the upper protruding part 17 by welding. The method of fixing the first positioning protrusions 17b is not limited to welding, provided that the fixed state can be maintained at extremely low temperatures.

[0080] A front notch 13d is provided at the left end of the front plate body 13a, and a rear notch 14a is provided on Petition 870260082298, dated 08 / 14 / 2026, page 26 / 140 / 61 left end of back plate 14. These notches 13d and 14a are provided for the purpose of, for example, making it possible to visually recognize whether the first freezing target 91 is accommodated in the first accommodation space SP10 from the outside or to facilitate the removal of the first freezing target 91 from the first accommodation space SP10.

[0081] Fall prevention protrusions 11b are provided on the left lateral edge of the bottom plate 11 (the lower end edge of the entrance / exit OP1). The fall prevention protrusions 11b are provided for the purpose of preventing falls of the first freeze target 91 accommodated in the first accommodation space SP10. Even if the first accommodation unit 10 is obliquely inclined downwards on the left side, the first freeze target 91 is locked onto the fall prevention protrusions 11b and remains in the first accommodation space SP10. <Segunda unidade de acomodação 20>

[0082] The second accommodation unit 20 illustrated in Figure 3 has a basic configuration in common with the first accommodation unit 10 mentioned previously. That is, the second accommodation unit 20 is also a box-shaped element having a bottom plate 21, a top plate 22, a front plate 23, a back plate 24 and a right side plate 25 and having an opening OP2 on the left side. The internal space of the second accommodation unit 20 is a second accommodation space SP20 that accommodates the second freezing target 92 (see Figure 1). A front notch 23d and a rear notch 24a are provided at the left end of a body of the front plate 23a and at the left end of the back plate 24, respectively, and fall prevention protrusions 21b are provided on the left side edge of the bottom plate 21. Each part of the second accommodation unit 20 is also formed by a Petition 870260082298, dated 08 / 14 / 2026, page 27 / 140 / 61 element that is not damaged (e.g., corroded) even at extremely low temperatures, for example, a stainless steel material.

[0083] A front end portion 21a of the bottom plate 21 and a bottom end portion 23b of the front plate 23 form the lower protruding piece 26, and a front end portion 22a of the top plate 22 and a top end portion 23c of the front plate 23 form an upper protruding piece 27. The pair of second positioning gaps 26c are provided on the left and right parts of the lower protruding piece 26. The second positioning gaps 26c are formed, for example, by cutting the lower protruding piece 26 into a square shape, and the first positioning protrusions 17b of the first accommodation unit 10 fit into it when the second accommodation unit 20 is placed on the first accommodation unit 10.

[0084] A second lower insertion opening 26b is provided on the right side of the lower protruding part 26 on the left side of the second right positioning void 26c. The second lower insertion opening 26b is a through hole having a size that allows the shaft body 81 to be inserted through it.

[00105] Figure 7 is an explanatory diagram of the 80A shaft element. As illustrated in Figure 7, the 80A shaft element includes the body. Petition 870260082298, dated 08 / 14 / 2026, page 35 / 140 / 61 of shaft 81 in the form of a bar, the male screw portion 82 provided at the distal end of the shaft body 81 and a handle 83 provided at the proximal end of the shaft body 81.

[00106] In the present embodiment, the shaft body 81 consists of a round bar made of stainless steel and having rigidity capable of collectively lifting the four accommodation units 10, 20, 30 and 40 that accommodate the freezing targets 91, 92, 93 and 94 respectively. A male screw capable of being coupled to each of the female screw elements 16a, 26a, 36a and 46a described above is formed on the outer peripheral surface of the male screw portion 82. The handle 83 is a portion to be gripped when the shaft body 81 is rotated around the center of the shaft and when the group of accommodation units 1 that accommodates the freezing target group 90 is placed in and removed from the storage space SP323. The handle 83 of the present embodiment is a so-called T-shaped handle and is provided by attaching a bar-shaped element to the proximal end of the shaft body 81 in a direction perpendicular to the axial direction of the shaft body 81 by welding or similar means. <Pedestal 200>

[00107] Figure 8A is a front view of pedestal 200, Figure 8B is a left side view of pedestal 200, Figure 8C is a plan view of pedestal 200, and Figure 8D is a perspective view of pedestal 200.

[00108] When the SP323 storage space of the 300 freezing container is cooled to an extremely low temperature by the refrigerant LQN, such as liquid nitrogen, the air in the SP323 storage space is liquefied to become liquid air LQA, which accumulates in the SP323 storage space. The pedestal 200 illustrated in Figures 8A to 8D is an element to prevent contact of the accommodation unit group 1 (accommodation units 10, 20, 30 and 40) with the liquid air LQA and is used for the purpose of arranging the accommodation unit group 1 above the Petition 870260082298, dated 08 / 14 / 2026, page 36 / 140 / 61 background surface of storage space SP323.

[00109] As illustrated in Figures 8A to 8D, the pedestal 200 includes the support plate 201 having a quadrangular shape in plan view, a pair of legs 202 (a first leg 202a and a second leg 202b) respectively extending downwards from one side edge (e.g., the left side edge in Figure 8A) of the support plate 201 and from the other side edge (e.g., the right side edge in Figures 8A to 8D) opposite a side edge, and a guide portion 203 extending upwards from the other side edge of the support plate 201. The pedestal 200 is made of a material having resistance to extremely low temperatures, for example, it is formed from a stainless steel plate.

[00110] The support plate 201 is a plate-shaped element on which the group of accommodation units 1 (the first accommodation unit 10 located at the bottom in the example in Figure 6) is placed and has a circular opening 201a provided in the center. When the pedestal 200 is moved, an operator's finger or a hook provided at the distal end of an operating rod (not shown) is inserted into the opening 201a.

[00111] The first leg 202a provided on one side edge of the support plate 201 consists of a plate-shaped element having a quadrangular shape. In the present embodiment, the first leg 202a is integrally provided with the support plate 201 by folding a stainless steel plate. The second leg 202b provided on the other side edge of the support plate 201 consists of a plate-shaped element having a folded piece 202b1 folded to the right on each of the front and rear side edges thereof. When the pedestal 200 is inserted into the storage space SP323, the lower ends of the first leg 202a and the second leg 202b touch the bottom surface of the storage space SP323. Consequently, the support plate 201 is arranged higher than the bottom surface of the space. Petition 870260082298, dated 08 / 14 / 2026, page 37 / 140 / 61 storage SP323 by the height of the first leg 202a or the second leg 202b.

[00112] The guide portion 203 is an element for guiding each of the accommodation units 10, 20, 30 and 40 when the group of accommodation units 1 is placed in and removed from the storage space SP323, and has a guide surface 203a with which the right-hand side surface of each accommodation unit 10, 20, 30 or 40 comes into contact.

[00113] The guide surface 203a extends upwards from the other side edge (e.g., the right side edge in Figure 8A) of the support plate 201. When the right-side surface of each accommodation unit 10, 20, 30, or 40 is forced to slide along the guide surface 203a, the group of accommodation units 1 can be placed in and removed from the storage space SP323 without difficulty.

[00114] In addition, a right-bent piece 203b is provided on each of the front side edge and the rear side edge of the guide portion 203. In the present embodiment, the guide portion 203 is integrally provided with the second leg 202b bending a stainless steel plate. <Elemento de guia>

[00115] Figure 9A is a plan view of a guide element 400, Figure 9B is a front view of the guide element 400, and Figure 10 is a plan view of the freezing container 300 with the guide element 400 connected to it.

[00116] Because the SP323 storage space of the 300 freezing container is cooled to an extremely low temperature, the upper SP324 space of the 300 freezing container may become clouded by air humidity, and it may be difficult to visually distinguish the SP323 storage space. The 400 guide element is an element that guides the distal end (lower end) of the 80A shaft element. Petition 870260082298, dated 08 / 14 / 2026, p. 38 / 140 / 61 for each of the female screw elements 16a, 26a, 36a and 46a, respectively included in the accommodation units 10, 20, 30 and 40, even in a situation where it is difficult to visually recognize the SP323 storage space.

[00117] As illustrated in Figure 9A and Figure 9B, the guide element 400 includes a guide body 401 having a substantially trapezoidal shape in plan view and a pair of left and right handles 402 provided on the upper surface of the guide body 401. Four guide grooves 411, 412, 413 and 414 are provided in a central portion of the guide body 401 in the right-to-left direction, extending forward from the rear end edge.

[00118] The width of each of the guide grooves 411 to 414 is aligned with the width of the shaft body 81, and the gap in the right-left direction between the guide grooves 411 to 414 is aligned with the pitch of the four upper insertion openings 47a1 to 47a4 described above (see Figure 10). All guide grooves 411 to 414 have the same length.

[00119] A pair of positioning holes 403 are formed at the left and right ends of the guide body 401. As illustrated in Figure 10, the guide element 400 is fixed to the opening portion 316 of the freezing container 300. For example, by aligning the positions of the positioning holes 403 of the guide body 401 with fixing screws 318 provided on the upper surface of the opening portion 316 and fitting the fixing screws 318 into the positioning holes 403, respectively, the guide element 400 is fixed to a predetermined position of the opening portion 316.

[00120] When the guide element 400 is fixed to the opening portion 316, the front ends of the four guide grooves 411 to 414 are positioned directly above the fourth upper insertion openings. Petition 870260082298, dated 08 / 14 / 2026, page 39 / 140 / 61 corresponding 47a1 to 47a4, respectively. Therefore, by inserting the shaft body 81 into one of the desired guide grooves 411 to 414, moving the shaft body 81 to the front end of one of the guide grooves 411 to 414, and then moving the shaft body 81 downwards, it is possible to easily insert the distal end of the shaft body 81 into the fourth upper insertion opening corresponding 47a1 to 47a4.

[00121] Furthermore, in a state where the shaft body 81 is inserted into the corresponding fourth upper insertion opening 47a1 to 47a4, when the shaft body 81 is pressed against the front end of one of the guide grooves 411 to 414, the angle of the shaft body 81 is fixed. When the shaft element 80A is moved downwards with the angle of the shaft body 81 fixed, the male screw portion 82 can be guided to the corresponding female screw element 16a to 46a.

[00122] When the male screw portion 82 is coupled to the corresponding female screw element 16a to 46a, the guide element 400 is removed from the opening portion 316. <Método de uso do aparelho de acomodação 100A>

[00123] The following describes a method of using the 100A accommodation device according to the first embodiment.

[00124] Figure 11 is an explanatory diagram of a storage procedure for pedestal 200 in storage space SP323 of freezing container 300; Figure 12 is an explanatory diagram of a storage procedure for accommodation device 100A with freezing target group 90 accommodated in the same in storage space SP323 of freezing container 300; Figure 13 is an explanatory diagram of a procedure when freezing targets 93 and 94 are removed from freezing targets 91 to 94 stored in storage space SP323; and Figure 14 is an explanatory diagram of a procedure when all freezing targets 91 to 94 Petition 870260082298, dated 08 / 14 / 2026, page 40 / 140 / 61 stored in storage space SP323 are removed.

[00125] In the following description, freezing targets 91 to 94 are a plurality of vials, each stored in a box, for example, and Figures 12 to 14 illustrate the box that houses the vials contained therein.

[00126] As illustrated in Figure 11, the pedestal 200 is stored in storage space SP323 of the freezing container 300. The pedestal 200 is stored, for example, by hooking the distal end of a hook (not shown) of an operating rod or an operator's finger into the opening 201a (see Figure 8C) provided in the support plate 201 and inserting the operating rod or an operator's arm into storage space SP323. In the example shown, the liquid absorbent SPG is stored in storage space SP323 before the pedestal 200 is stored.

[00127] As illustrated in Figure 12, after pedestal 200 is stored, the accommodation unit group 1 (the freezing target group 90) is stored in storage space SP323. In the illustrated example, the second accommodation unit 20 with the second freezing target 92 accommodated in it is placed in the first accommodation unit 10 with the first freezing target 91 accommodated in it, the third accommodation unit 30 with the third freezing target 93 accommodated in it is placed in the second accommodation unit 20, and the fourth accommodation unit 40 with the fourth freezing target 94 accommodated in it is placed in the third accommodation unit 30. The male screw portion 82 of the shaft element 80A is coupled to the first female screw element 16a included in the first accommodation unit 10.

[00128] The operator grasps handle 83 of shaft element 80A and stores the group of accommodation units 1 in the storage space. Petition 870260082298, dated 08 / 14 / 2026, page 41 / 140 / 61 SP323. When accommodation unit group 1 is stored, accommodation unit group 1 is moved downwards with its right-hand side surface resting against the guide surface 203a of pedestal 200. Thus, accommodation unit group 1 can be stored in storage space SP323 without difficulty.

[00129] After the accommodation unit group 1 is placed on the support plate 201, the shaft element 80A is rotated in the reverse direction of the male screw portion 82 to release the coupling state between the shaft element 80A and the first female screw element 16a, and the shaft element 80A is pulled upwards. Thus, the storage of the accommodation unit group 1 in the storage space SP323 is completed.

[00130] In a case of removing each of the accommodation units 10 to 40 (each of the freezing targets 91 to 94) stored in storage space SP323, as described with reference to Figure 10, the guide element 400 is fixed to the opening portion 316 of the freezing container 300 before coupling the shaft element 80A.

[00131] In this case, the male screw portion 82 of the shaft element 80A is coupled to one of the female screw elements 16a to 46a that is included in one of the accommodation units 10 to 40 to be removed. In this case, by inserting the shaft body 81 into one of the desired guide grooves 411 to 414 (see Figure 10), moving the shaft body 81 to the front end of one of the desired guide grooves 411 to 414 and then moving the shaft body 81 downwards, it is possible to easily insert the shaft body 81 into the corresponding fourth upper insertion opening 47a1 to 47a4. As a result, one of the desired female screw elements 16a to 46a and the male screw portion 82 can be easily coupled to each other. Petition 870260082298, dated 08 / 14 / 2026, p. 42 / 140 / 61

[00132] After the male screw portion 82 is coupled to the corresponding female screw element 16a to 46a, the guide element 400 is removed from the opening portion 316.

[00133] As indicated by the solid line in Figure 13, when the shaft body 81 is inserted into the fourth upper insertion opening 47a3, which is the second from the left, so that the distal end (lower end) of the male screw portion 82 touches the third female screw element 36a, and then the shaft body 81 is rotated in the forward direction of the male screw, the male screw portion 82 and the third female screw element 36a are coupled to each other.When the shaft element 80A is pulled up with the male screw portion 82 coupled to the third female screw element 36a, the third accommodation unit 30 (the third freezing target 93) and the fourth accommodation unit 40 (the fourth freezing target 94) can be removed, while the first accommodation unit 10 (the first freezing target 91) and the second accommodation unit 20 (the second freezing target 92) are left in the storage space SP323 of the freezing container 300.

[00134] As indicated by the dotted line in Figure 13, by inserting the shaft body 81 into the fourth leftmost upper insertion opening 47a4 to couple the male screw portion 82 and the fourth female screw element 46a to each other, and then pulling up the shaft element 80A, only the fourth accommodation unit 40 (the fourth freezing target 94) can be removed from the storage space SP323 of the freezing container 300.

[00135] As illustrated in Figure 14, inserting the shaft body 81 into the fourth upper insertion opening 47a1 further to the right to couple the male screw portion 82 and the first female screw element 16a to each other, and then pulling up the shaft element 80A, the first to Petition 870260082298, dated 08 / 14 / 2026, page 43 / 140 / 61 fourth accommodation unit 10 to 40 (the first to fourth freezing target 91 to 94) can be collectively removed from storage space SP323 of freezing container 300.

[00136] As described above, when the 100A accommodation device according to the first embodiment is used, it is possible to remove a freeze target to be removed while leaving a freeze target not to be removed in the SP323 storage space, by selecting one of the 16a to 46a female screw elements to which the 80A shaft element must be coupled.

[00137] For example, when the shaft element 80A is coupled to the second female screw element 26a of the second accommodation unit 20 and then pulled up, the second accommodation unit 20 (the second freeze target 92), the third accommodation unit 30 (the third freeze target 93) and the fourth accommodation unit 40 (the fourth freeze target 94) can be removed while the first accommodation unit 10 (the first freeze target 91) is left in the storage space SP323.

[00138] In the accommodation apparatus 100A according to the present embodiment, it is not necessary to ensure a passage to allow a selected accommodation unit to pass over the selected accommodation unit. Therefore, the size of each of the accommodation units 10 to 40 stored in the SP323 storage space can be maximized according to the SP323 storage space, so that the quantity of freezing targets can be increased compared to a use case of a conventional accommodation apparatus. <Segunda modalidade>

[00139] Figure 15A is a perspective view of a first accommodation unit 10B in a first stage (lowest stage) Petition 870260082298, dated 08 / 14 / 2026, page 44 / 140 / 61 included in an accommodation device 100B according to a second embodiment, Figure 15B is a perspective view of a second accommodation unit 20B in a second stage (intermediate stage), Figure 15C is a cross-sectional view of each of the female screw elements 16B and 26B, and Figure 15D is a cross-sectional view to explain a state in which the male screw portion 82 of the shaft element 80A and the second female screw element 26B are screwed together.

[00140] In the accommodation apparatus 100A according to the first embodiment described above, the female screw elements 16a to 46a were made of nuts made of stainless steel and were fixed to the upper surfaces of the lower protruding parts 16 to 46 by welding, respectively. Therefore, the lower ends of the female screw elements 16a to 46a were closed by the lower protruding parts 16 to 46, respectively.

[00141] In a case where the effective screw length of the male screw portion 82 included in the shaft element 80A is greater than the female screw length of each of the female screw elements 16a to 46a, if the male screw portion 82 of the shaft element 80A is excessively fastened to each of the female screw elements 16a to 46a, the corresponding lower protruding part 16 to 46 is pushed down by the shaft element 80A. As a result, there is a risk that each of the female screw elements 16a to 46a may detach from the corresponding lower protruding part 16 to 46.

[00142] In view of these circumstances, in the accommodation apparatus 100B according to the second embodiment, as each female screw element (the first female screw element 16B and the second female screw element 26B are illustrated in Figures 15A to 15D), an element with a penetrating female screw in the axial direction formed in Petition 870260082298, dated 08 / 14 / 2026, page 45 / 140 / 61 internal peripheral surface thereof.

[00143] The accommodation apparatus 100B according to the second embodiment is described below and configurations identical to those of the accommodation apparatus 100A according to the first embodiment are denoted by similar reference signs and explanations thereof are omitted.

[00144] As illustrated in Figure 15A, the first accommodation unit 10B of the accommodation apparatus 100B according to the second embodiment also includes the bottom plate 11, the top plate 12, the front plate 13, the rear plate 14 and the right side plate 15, and has the inlet / outlet OP1 for the first freezing target 91 on the left side.

[00145] The front end part 11a of the bottom plate 11 and the bottom end part 13b of the front plate 13 are joined together to form the lower protruding part 16, and the front end part 12a of the top plate 12 and the top end part 13c of the front plate 13 are joined together to form the upper protruding part 17.

[00146] The first female screw element 16B is fixed to the lower protruding part 16.

[00147] As illustrated in Figure 15C, the first female screw element 16B includes a female screw body 161 having a hollow cylindrical shape, a female screw 162 provided on the inner peripheral surface of the female screw body 161 and a flange 163 extending from the lower end of the female screw body 161 outward in the radial direction.

[00148] The female screw body 161 is inserted from below into a mounting opening 16d provided in the lower protruding part 16, and the flange 163 rests against the lower surface of the lower protruding part 16. For example, an opening larger than the outside diameter of the flange 163 is provided. Petition 870260082298, dated 08 / 14 / 2026, page 46 / 140 / 61 on the front end part 11a of the bottom plate 11, and flange 163 is arranged in this opening.

[00149] In the present embodiment, the first female screw element 16B is fixed to the lower protruding part 16 by welding the female screw body 161 and the upper surface of the lower protruding part 16 together and welding the flange 163 and the lower surface of the lower protruding part 16 together. Although not illustrated in the drawings, the pedestal 200 of the present embodiment has a lateral insertion opening of the support plate, through which the male screw portion 82 of the shaft body 81 can be inserted into the support plate 201 directly below the first female screw element 16B.

[00150] Two first upper insertion openings 17a1 and 17a2 are provided in the upper protruding part 17. One first upper insertion opening 17a1 is provided in a position directly above the first female screw element 16B, and the other first upper insertion opening 17a2 is provided on the left side of the first upper insertion opening 17a1.

[00151] As illustrated in Figure 15B, the second accommodation unit 20B of the accommodation apparatus 100B according to the second embodiment also includes the bottom plate 21, the top plate 22, the front plate 23, the rear plate 24 and the right side plate 25, and has the inlet / outlet OP2 for the second freezing target 92 on the left side.

[00152] The second lower insertion opening 26b is provided in the lower protruding part 26 of the second accommodation unit 20B, and the second female screw element 26B is fixed on the left side of the second lower insertion opening 26b.

[00153] As illustrated in Figure 15C, the second female screw element 26B includes the female screw body 161, the female screw 162, and the flange 163, similarly to the first screw element. Petition 870260082298, dated 08 / 14 / 2026, page 47 / 140 / 61 female 16B. The female screw body 161 is inserted from below into the mounting opening 26d and fixed to the lower protruding part 26 by welding. When the second accommodation unit 20B is placed in the first accommodation unit 10B, the second female screw element 26B is arranged directly above the first upper insertion opening 17a2 of the first accommodation unit 10B.

[00154] Three second upper insertion openings 27a1, 27a2 and 27a3 are provided in the upper protruding part 27 at a regular interval along the right-to-left direction. The second right upper insertion opening 27a1 is provided in a position directly above the second lower insertion opening 26b, and the second central upper insertion opening 27a2 is provided in a position directly above the second female screw element 26B.

[00155] As illustrated in Figure 15D, when the second accommodation unit 20B is placed in the first accommodation unit 10B, the position of the lower end opening of the second female screw element 26B is aligned with the position of the first upper insertion opening 17a2 of the first accommodation unit 10B. Consequently, even if the shaft element 80A is excessively fastened to the second female screw element 26B, the male screw portion 82 of the shaft element 80A passes through the first upper insertion opening 17a2. Therefore, the inconvenience of the second female screw element 26B coming loose from the lower protruding part 26 of the second accommodation unit 20B is avoided.

[00156] Similarly, when the first accommodation unit 10B is placed on the support plate 201, the position of the lower end opening of the first female screw element 16B is aligned with the position of a side insertion opening of the support plate 201b (indicated by the dashed line in Figure 8C) provided on the support plate 201. Petition 870260082298, dated 08 / 14 / 2026, page 48 / 140 / 61 Consequently, even if the shaft element 80A is excessively fastened to the first female screw element 16B, the lower end of the shaft element 80A passes through the side insertion opening of the support plate 201b. Therefore, the inconvenience of the first female screw element 16B coming loose from the lower protruding part 16 of the first accommodation unit 10B is avoided.

[00157] In the accommodation apparatus 100B according to the second embodiment, although not illustrated in the drawings, the third accommodation unit and the fourth accommodation unit are also configured similarly to the first accommodation unit 10B and the second accommodation unit 20B. <Terceira modalidade>

[00158] Figure 16A is a perspective view of a 10C accommodation unit in a first stage (lowest stage) included in a 100C accommodation apparatus according to a third embodiment, Figure 16B is a perspective view of a 20C or 30C accommodation unit in a second or third stage (intermediate stage), Figure 16C is a perspective view of a 40C accommodation unit in a fourth stage (highest stage), and Figure 17 is an explanatory diagram of a method of using the 100C accommodation apparatus according to the third embodiment.

[00159] In each of the accommodation devices 100A and 100B of the first and second embodiments described above, the positions of the female screw elements 16a to 46a included in the respective accommodation units 10 to 40 or the positions of the female screw elements 16B and 26B included in the respective accommodation units 10B and 20B are provided to be offset from each other in the plan view. However, the configuration of the female screw elements is not limited to this.

[00160] In the accommodation apparatus 100C according to the third Petition 870260082298, dated 08 / 14 / 2026, p. 49 / 140 / 61 modality, the characteristic configuration is the position of the respective female screw elements 16C to 46C aligned with each other in the plan view, in a state where the respective accommodation units 10C to 40C are stacked.

[00161] The accommodation apparatus 100C according to the third embodiment is described below and configurations identical to those of the accommodation apparatus 100A and 100B according to the first and second embodiments are denoted by similar reference signs and explanations thereof are omitted.

[00162] As illustrated in Figure 16A, the first accommodation unit 10C of the accommodation apparatus 100C according to the third embodiment also includes the bottom plate 11, the top plate 12, the front plate 13, the rear plate 14 and the right side plate 15, and has the inlet / outlet OP1 for the first freezing target 91 on the left side.

[00163] The front end part 11a of the bottom plate 11 and the bottom end part 13b of the front plate 13 are joined together to form the lower protruding part 16, and the front end part 12a of the top plate 12 and the top end part 13c of the front plate 13 are joined together to form the upper protruding part 17.

[00164] The first female screw element 16C is a cylindrical element having a length corresponding to the distance between the lower protruding part 16 and the upper protruding part 17, and is provided with a female screw on its inner peripheral surface, the female screw being capable of being coupled to a male screw provided in a male screw portion 82C (see Figure 17) of a shaft element 80C. The first female screw element 16C is formed from a stainless steel material, for example, and is fixed to each of the lower protruding parts 16 and to the upper protruding parts 17 by welding or similar means. In the third embodiment, the first female screw element Petition 870260082298, dated 08 / 14 / 2026, page 50 / 140 / 61 16C is fixed in a substantially intermediate position in the right-to-left direction on each of the lower protruding part 16 and the upper protruding part 17.

[00165] A first lower insertion opening (not illustrated) is provided in the lower protruding part 16 directly below the first female screw element 16C (in more detail, directly below the female screw included in the first female screw element 16C), the first lower insertion opening having a size that allows the shaft body 81 to be inserted through it. Similarly, the first upper insertion opening 17a is provided in the upper protruding part 17 directly above the first female screw element 16C (in more detail, directly above the female screw included in the first female screw element 16C), the first upper insertion opening 17a having a size that allows the shaft body 81 to be inserted through it.Therefore, the male screw portion 82C of the shaft element 80C can cause its lower end to protrude from the lower protruding part 16 while it is coupled to the first female screw element 16C.

[00166] As illustrated in Figure 16B, the second accommodation unit 20C and the third accommodation unit 30C also include bottom plates 21 and 31, top plates 22 and 32, front plates 23 and 33, rear plates 24 and 34, and right side plates 25 and 35, and have inlet / outlet OP2 for the second freeze target 92 and inlet / outlet OP3 for the third freeze target 93 on their left sides.

[00167] The front end portion 21a of the bottom plate 21 and the bottom end portion 23b of the front plate 23 are joined together to form the lower protruding piece 26, and the front end portion 22a of the top plate 22 and the top end portion 23c of the front plate 23 are Petition 870260082298, dated 08 / 14 / 2026, page 51 / 140 / 61 joined together to form the upper protruding piece 27. Similarly, the front end part 31a of the bottom plate 31 and the lower end part 33b of the front plate 33 are joined together to form the lower protruding piece 36, and the front end part 32a of the top plate 32 and the upper end part 33c of the front plate 33 are joined together to form the upper protruding piece 37.

[00168] A second female screw element 26C and a third female screw element 36C have the same configuration as the first female screw element 16C described above and are each fixed to the lower protruding part 26 or 36 and the upper protruding part 27 or 37 by welding, for example. Each of the second female screw elements 26C and the third female screw element 36C is also fixed in a substantially intermediate position in the right-left direction on the lower protruding part 26 or 36 and the upper protruding part 27 or 37, similarly to the first female screw element 16C.Therefore, when the 10C, 20C, and 30C accommodation units are viewed from above in a state where the second 20C accommodation unit is placed in the first 10C accommodation unit and the third 30C accommodation unit is placed in the second 20C accommodation unit, the positions of the second 26C female screw element and the third 36C female screw element are aligned with the position of the first 16C female screw element.

[00169] A second lower insertion opening (not shown) is provided in the lower protruding part 26 directly below the second female screw element 26C, and a second upper insertion opening 27a is provided in the upper protruding part 27 directly above the second female screw element 26C. Similarly, a third lower insertion opening (not shown) is provided in the lower protruding part 26 directly below the third female screw element 36C, and Petition 870260082298, dated 08 / 14 / 2026, page 52 / 140 / 61 a third upper insertion opening 37a is provided in the upper protruding part 27 directly above the third female screw element 36C.

[00170] Therefore, the male screw portion 82C of the shaft element 80C can cause its lower end to protrude from the lower protruding part 26 or 36 while it is coupled to the second female screw element 26C or the third female screw element 36C.

[00171] As illustrated in Figure 16C, the fourth accommodation unit 40C also includes the bottom plate 41, the top plate 42, the front plate 43, the rear plate 44 and the right side plate 45, and has the inlet / outlet OP4 for the fourth freezing target 94 on the left side.

[00172] The front end part 41a of the bottom plate 41 and the bottom end part 43b of the front plate 43 are joined together to form the lower protruding part 46, and the front end part 42a of the top plate 42 and the top end part 43c of the front plate 43 are joined together to form the upper protruding part 47.

[00173] The fourth female screw element 46C also has the same configuration as the first female screw element 16C described above and is fixed in a substantially intermediate position in the right-left direction in each of the lower protruding part 46 and the upper protruding part 47 by welding, for example. Therefore, when the accommodation units 10C to 40C stacked on top of each other are viewed from above, the respective positions of the female screw elements 16C to 46C are aligned with each other.

[00174] In addition, a fourth lower insertion opening (not shown) is provided in the lower protruding part 46 directly below the fourth female screw element 46C, and a fourth upper insertion opening 47a is provided in the upper protruding part 47 directly above the fourth female screw element 46C. Therefore, the male screw portion 82C of the shaft element 80C can cause its end Petition 870260082298, dated 08 / 14 / 2026, page 53 / 140 / 61 lower part projects from the lower protruding piece 46 while it is coupled to the fourth female screw element 46C.

[00175] In the accommodation apparatus 100C according to the third embodiment, each of the female screw elements 16C to 46C is fixed to the corresponding lower protruding part 16 to 46 and to the corresponding upper protruding part 17 to 47 with the position of the female screw in the circumferential direction aligned with the male screw of the male screw portion 82C of the shaft element 80C.

[00176] As illustrated in Figure 17, when the shaft body 81 is rotated in the positive direction in a state where the accommodation units 10C to 40C are stacked one on top of the other, the distal end part of the male screw portion 82C is coupled first to the fourth female screw element 46C and then to the third female screw element 36C. When the shaft body 81 is rotated further in the positive direction, the distal end part of the male screw portion 82C is coupled to the second female screw element 26C and to the first female screw element 16C in that order.

[00177] The shaft element 80C is formed by a round bar made of stainless steel, for example, and includes the shaft body 81 in the form of a bar, the male screw portion 82C provided on the distal end side from an intermediate position in the axial direction of the shaft body 81, a scale portion 84C provided on the proximal end side from an intermediate position in the axial direction of the shaft body 81, and the handle 83 provided on the proximal end of the shaft body 81.

[00178] A male screw capable of being coupled to the female screw of each of the 16C to 46C female screw elements is provided in the male screw portion 82C. The scale portion 84C indicates the insertion depth of the male screw portion 82C in each 16C, 26C, 36C or 46C female screw element and, in the example of Figure 17, includes four Petition 870260082298, dated 08 / 14 / 2026, p. 54 / 140 / 61 scales provided along the circumferential direction, the scales being organized in intervals along the axial direction.

[00179] A first scale 84a provided closest to handle 83 among the four scales corresponds to the first accommodation unit 10C. For example, when the shaft body 81 is forced into each of the female screw elements 16C to 46C until the first scale 84a reaches the height of the opening portion 316 of the freezing container 300, the distal end part of the male screw portion 82C is positioned on the first female screw element 16C. Therefore, when the shaft element 80C is pulled up in a state where the shaft body 81 is inserted until the first scale 84a is at the same height as the opening portion 316 of the freezing container 300, the four accommodation units 10C to 40C can be collectively removed from the freezing container 300.

[00180] A second scale 84b which is the second on the handle side 83 corresponds to the second accommodation unit 20C. For example, when the shaft body 81 is forced into each of the female screw elements 26C to 46C until the second scale 84b reaches the height of the opening portion 316 of the freezing container 300, the distal end part of the male screw portion 82C is positioned in the second female screw element 26C. Therefore, when the shaft element 80C is pulled up in a state where the shaft body 81 is inserted until the second scale 84b is at the same height as the opening portion 316 of the freezing container 300, the second accommodation unit 20C, the third accommodation unit 30C, and the fourth accommodation unit 40C can be collectively removed from the freezing container 300, while the first accommodation unit 10C is left in the freezing container 300.

[00181] A third scale 84c which is the third on the handle side 83 Petition 870260082298, dated 08 / 14 / 2026, p. 55 / 140 / 61 corresponds to the third accommodation unit 30C. For example, when the shaft body 81 is forced into the female screw elements 36C and 46C until the third scale 84c reaches the height of the opening portion 316 of the freezing container 300, the distal end part of the male screw portion 82C is positioned in the third female screw element 36C. Therefore, when the shaft element 80C is pulled up in a state where the shaft body 81 is inserted until the third scale 84c is at the same height as the opening portion 316 of the freezing container 300, the third accommodation unit 30C and the fourth accommodation unit 40C can be collectively removed from the freezing container 300 while the first accommodation unit 10C and the second accommodation unit 20C are left in the freezing container 300.

[00182] A fourth scale 84d closer to the male screw portion 82C corresponds to the fourth accommodation unit 40C. For example, when the shaft body 81 is forced into the fourth female screw element 46C until the fourth scale 84d reaches the height of the opening portion 316 of the freezing container 300, the distal end part of the male screw portion 82C does not reach the third female screw element 36C. Therefore, when the shaft element 80C is pulled up in a state where the shaft body 81 is inserted until the fourth scale 84d is at the same height as the opening portion 316 of the freezing container 300, only the fourth accommodation unit 40C can be removed from the freezing container 300, while the first accommodation unit 10C, the second accommodation unit 20C, and the third accommodation unit 30C are left in the freezing container 300.

[00183] In the 100C accommodation apparatus according to the third embodiment, a female screw element with a bottom that is closed at the lower end can be used as the first screw element. Petition 870260082298, dated 08 / 14 / 2026, page 56 / 140 / 61 female 16C. Furthermore, it is not necessary to provide the first lower insertion opening in the lower protruding part 16. <Outras modalidades>

[00184] In the accommodation device 100A according to the first embodiment, a coupled portion to be coupled to the shaft element 80C is constituted by each of the female screw elements 16a to 46a. However, the configuration of the coupled portion is not limited to this.

[00185] Figure 18 is an explanatory diagram of a 100D accommodation apparatus according to a fourth embodiment. In the 100D accommodation apparatus according to the fourth embodiment, the 10D, 20D, 30D and 40D accommodation units that constitute a group of 1D accommodation units include 16D, 26D, 36D and 46D male screw elements as coupled portions to be coupled to an 80D shaft element, respectively. Each of the 16D to 46D male screw elements includes a male screw portion having a male screw formed on its outer peripheral surface and is constituted by a hexagonal head screw, for example. Furthermore, the lower end is fixed to the corresponding lower protruding piece 16 to 46 with the male screw portion directed upwards.In connection with this configuration, at the lower end of the shaft body 81 of the shaft element 80D, a female screw portion 82D is provided which can be coupled to the male screw portion of each of the male screw elements 16D to 46D. The female screw portion 82D is a tubular element having a female screw on its inner peripheral surface.

[00186] Also in the accommodation apparatus 100D according to the fourth embodiment, operational effects identical to those of the accommodation apparatus 100A can be obtained according to the first embodiment.

[00187] In accommodation devices 100A, 100B, 100C and 100D according to the respective modalities described above, the axis elements Petition 870260082298, dated 08 / 14 / 2026, p. 57 / 140 / 61 80A, 80C, and 80D are configured to be removable from each of the accommodation units 10 to 40 or similar. However, the configuration of the shaft element is not limited to this. Figure 19 is an explanatory diagram of an accommodation device 100E according to a fifth embodiment.

[00188] The 100E accommodation device according to the fifth embodiment is characterized by integrally provided shaft portions 80E1, 80E2, 80E3 and 80E4, in place of the female screw elements (the coupled portions) 16a to 46a of the first embodiment. Therefore, the configuration of a group of 1E accommodation units (10E, 20E, 30E and 40E accommodation units) not illustrated in Figure 19 is the same as each of the accommodation units 10 to 40 of the first embodiment illustrated in Figures 2 to 5. Consequently, detailed descriptions are omitted.

[00189] As illustrated in Figure 19, the first shaft portion 80E1 provided in the first accommodation unit 10E is arranged with its upper end located above the top plate 42 of the fourth accommodation unit 40E through the second lower insertion opening 26b and the second upper insertion opening 27a1 of the second accommodation unit 20E, the third lower insertion opening 36b1 and the third upper insertion opening 37a1 of the third accommodation unit 30E, and the fourth lower insertion opening 46b1 and the fourth upper insertion opening 47a1 of the fourth accommodation unit 40E.

[00190] The second shaft portion 80E2 provided in the second housing unit 20E is arranged with its upper end located above the top plate 42 of the fourth housing unit 40E through the third lower insertion opening 36b2 and the third upper insertion opening 37a2 of the third housing unit 30E, and the fourth lower insertion opening 46b2 and the fourth upper insertion opening 47a2 of the fourth housing unit 40E.
