Description

[Technical Field]

[0001] This invention relates to a protective pack for liquid medicine containers, which is optimal for protecting liquid medicine containers such as ampoules and vials containing liquid medicine when they are transported within a medical institution or when they are transported from a medical institution to the outside. [Background technology]

[0002] Generally, medical drugs handled in medical institutions and dispensing pharmacies are packaged in packaging materials or packaging boxes with cushioning properties to protect the drugs.

[0003] For example, ampoules and vials containing medicinal liquids are generally made of glass and are easily broken. When these ampoules and vials are packaged in a packaging box or bag for transport, they may be damaged by external impact. Ampoules are particularly susceptible to breakage. Therefore, when packaging ampoules and vials (hereinafter referred to as ampoules, etc.) in a box or bag, a cushioning material called a rondlation 6, as shown in FIG. 6, is used. The rondlation 6 is typically made of paper and formed into a corrugated shape with multiple recesses 60. Multiple ampoules A0, etc., are placed in each recess 60 and sandwiched between the protrusions 61 on both sides of each recess 60. This type of rondlation 6 is known from Patent Documents 1 and 2, etc. Ampoule A0, etc., are housed in such a rondlation 6, which is then sealed in a packaging box or bag. In this way, the ampoules and the like in the box or bag can be protected from impacts from outside the box or bag. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-116548 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-249034 Summary of the Invention [Problem to be solved by the invention]

[0005] Although ampoules and other liquid medicine containers are thus packaged in boxes or bags via rondlation and protected from external impacts, this protection is mainly limited to protection during transport of the ampoules and other liquid medicine containers from the manufacturer of the liquid medicine to the medical institution or dispensing pharmacy. In other words, when the liquid medicine container is removed from the box or bag to use the liquid medicine contained in the ampoules and other liquid medicine containers within the medical institution or other location, the liquid medicine container is usually not protected during subsequent transport within the medical institution or during transport from the medical institution to an external location.

[0006] For example, in university hospitals, medications dispensed for hospitalized patients are generally placed in a medicine bag for each patient, and these medicine bags are then placed together in baskets or trays for transport within the hospital and distribution to each patient. In this case, medications are dispensed in various dosage forms, but injections in particular are contained in ampoules. Because ampoules are made of glass and are vulnerable to impacts, simply placing the medication in a medicine bag poses a risk of being dropped and broken during transport within the hospital or during handling during that process.

[0007] To address this issue, some university hospitals and other facilities have adopted the following approach: cut the rondulation 6 at the center of each protrusion 61, as shown by the dashed lines in Figure 6, and use the resulting pieces as cushioning for each individual ampoule.

[0008] However, in large medical institutions such as university hospitals, the amount of medicinal liquid contained in medicinal liquid containers such as ampoules (hereinafter simply referred to as ampoules) used is large, and the reuse of rondulations as described above poses the problem that the work of cutting off the rondulations is very time-consuming and cumbersome.

[0009] The present invention aims to solve the above-mentioned problems of the prior art by providing a protective pack for a liquid medicine container that can be easily assembled and can easily protect the ampoules, etc. from external forces when they are used in a medical institution or when they are transported from the medical institution to the outside, and that can be provided relatively inexpensively. [Means for solving the problem]

[0010] In order to achieve the above object, the present invention A protective pack for a liquid medicine container that easily packages a liquid medicine container containing an ampoule during transportation and protects it from external forces, a main body that accommodates the liquid medicine container and is formed so as to be able to surround the liquid medicine container by contacting its peripheral surface and be able to be assembled from its original planar shape into a triangular prism shape; an opening formed across two of the three faces of the triangular prism shape of the main body, for exposing to the outside of the main body various information relating to the liquid medicine applied to the peripheral surface of the liquid medicine container, and a holding portion formed so as to be bendable from both side edges of the opening toward the inner surface of the triangular prism shape of the main body inwardly in a V-shaped cross section, for inserting and holding the liquid medicine container; a top surface side and a bottom surface side pressing portion formed on both ends of the main body so as to be foldable toward the inner surface side of the triangular prism shape of the main body and pressing the top surface and the bottom surface of a drug solution container to be stored in the main body; Equipped with The main body surrounds the liquid medicine container at three corners of the triangular prism shape of the main body via buffer spaces, the holding parts hold the liquid medicine container at four corners of a holding space defined in a quadrangle in a plan view between the holding parts and the two faces of the main body via buffer spaces, and the top and bottom pressing parts press and fix the top and bottom surfaces of the liquid medicine container inside the main body. The gist of this is as follows.

[0011] The present invention preferably further comprises the following features: The main body, the holding part, and the top and bottom pressing parts are formed from a single blank sheet of paperboard. The blank sheet is a two-sided main body portion having two surfaces for forming two of the three surfaces of the triangular prism shape of the main body; a single-surface main body portion having two surfaces connected to both sides of the two-surface main body portion and forming the remaining one of the three surfaces of the triangular prism shape of the main body; Two pressing portion shaped portions that are convexly connected to both end edges of the two surfaces of the main body two-surface shaped portion and form part of the pressing portions on the top surface side and the bottom surface side; Equipped with a central fold line and fold lines on both sides extending between the two faces of the two-face main body portion and between the two faces of the two-face main body portion and the two faces of the one-face main body portion, respectively, so that the two-face main body portion and the one-face main body portion can be assembled into a triangular prism shape; two notches formed on both end sides of the two-surface main body portion, respectively, in the vicinity of the fold line between the two faces of the two-surface main body portion and extending diagonally from a position inside the two-surface main body portion relative to both end edges of the two-surface main body portion toward the boundaries between the two faces of the two-surface main body portion and the two faces of the one-surface main body portion, in a V-shape as a whole, and arranged so that both end sides of the two-surface main body portion can be folded toward the inner surface of the two-surface main body portion as remaining portions of the pressing portions on the top and bottom faces; a pair of notches provided on the two-surface main body portion in parallel on both sides across the central fold line between the two faces of the two-surface main body portion so as to be able to form one pair of opening edge portions of the opening; a pair of notches extending discontinuously between both side ends of the one pair of notches so as to be able to form the other pair of opening edge portions of the opening and to be able to form a holding portion between the other pair of opening edge portions; and a central notch extending in the center between the other pair of notches in parallel to the other pair of notches so as to be able to fold the holding portion into a V-shaped cross section; The present invention is configured as follows.

[0012] In this case, the two pressing portions are each assembled into a triangular prism shape by a two-sided main body portion and a one-sided main body portion, and then the adjacent edges are butted together and folded into the triangular prism shape, forming a triangle so that both ends of the triangular prism shape can be closed.

[0013] In this case, the two surfaces of the one-surface main body portion are each formed to a size that allows them to overlap with each other when assembled together with the two-surface main body portion into a triangular prism shape, and the two surfaces of the one-surface main body portion are overlapped and fixed.

[0014] In this case, a locking portion protrudes from one of the two surfaces of the main body one-surface shaped portion on the side opposite the main body two-surface shaped portion, and a notch is provided between the other of the two surfaces of the main body one-surface shaped portion and the main body two-surface shaped portion so that the locking portion can engage with it, and the two surfaces of the one-surface shaped portion are fixed by engagement between the locking portion and the notch. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, an embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 show one embodiment of the present invention. Figure 1 shows the overall structure of a protective pack for a liquid medicine container when in use, and Figures 2 to 4 show the overall structure of the protective pack for a liquid medicine container in its original state before use.

[0018] As shown in FIG. 1, a protective pack P for a liquid medicine container (hereinafter referred to as this pack P) is designed to simply package a liquid medicine container including an ampoule containing the liquid medicine and protect it from external forces when the liquid medicine container is transported. Here, a pack used to package and protect an ampoule (hereinafter referred to as ampoule A0) for packaging an injection is particularly shown as an example. Here again, as previously mentioned, the injection contained in ampoule A0 will be simply referred to as an ampoule (hereinafter referred to as ampoule A).

[0019] Referring now to FIG. 6, the ampoule A0 is made of glass and comprises a body A01 containing a liquid medicine and a head A03 formed at the tip of the body A01 via a neck A02 and sealed by welding after the injection is placed inside the body A01. The body A01 is cylindrical with a large diameter, and the head A03 is cylindrical with a small diameter. A cut line A021 is provided on the neck A02. Various information L relating to the liquid medicine, such as the name, ingredients, and expiration date of the liquid medicine, is printed on the periphery of the body A01. In this case, a label L1 bearing the various information L relating to the liquid medicine may be affixed to the periphery of the body A01 of the ampoule A0, or the label L1 may be printed directly on the periphery of the body A01. The former is used here. When using the injection medicine in this ampoule A0, the head A03 is folded along the cut line A021 in the neck A02 from the body A01 to open the body A01. Then, the needle of a syringe is inserted into the body A01 and the injection medicine is drawn into the syringe.

[0020] As shown in Figure 1, this pack P is composed of a main body 1 that stores an ampoule A0, an opening 10 provided in the main body 1 that exposes various information L about the medicinal liquid that is applied to the peripheral surface of the ampoule A0 stored in the main body 1 to the outside of the main body 1, a holding portion 2 that inserts and holds the ampoule A0 within the main body 1, and top and bottom pressing portions 3U and 3D that press the top and bottom of the ampoule A0 within the main body 1.

[0021] The main body 1 is formed so that it can be assembled from its original planar shape into a triangular prism shape so that it can surround the periphery of the ampoule A0. In this case, the original shape of the main body 1 is formed as a rectangular flat plate (planar shape) having a length and width sufficient to surround the entire periphery of the head A03, neck A02, and body A01 of the ampoule A, with the body A01 of the ampoule A inscribed between two of the three faces 11, 12, and 13 forming the triangular prism, and folds 101, 102, and 103 are formed in this flat plate so that it can be assembled into a triangular prism shape with an equilateral triangular cross section. In this case, of the three faces 11, 12, and 13 forming the triangular prism shape, two faces 11 and 12 are elongated rectangles of the same size, and the remaining face 13 is a rectangle whose length is the same as the long sides of the rectangles of the two faces 11 and 12 and whose width is the same as the short sides of these rectangles. When these three surfaces 11, 12, and 13 are assembled, the body A01 of the ampoule A0 is inscribed between two of the surfaces 11 and 12, and the remaining surface 13 is slightly spaced from the body A01 of the ampoule A0. Furthermore, fixing portions 4 (see FIG. 2) are provided on both sides of this flat plate forming the original shape to secure the main body 1 after assembly into a triangular prism shape. The fixing portions 4 may be fixed in any manner that secures the main body 1 into a triangular prism shape, such as by engaging a locking recess with a locking protrusion, by engaging a locking claw with a locking hole, or by bonding a fixing portion with a fixed portion. Here, the fixing portions 4 are formed by engaging a locking portion 41 with a notch 40. In this case, the locking portion 41 is formed on one of the connecting ends of the three surfaces 11, 12, and 13 of the main body 1, and a notch 40 is formed on the other, and the main body 1 is secured by the engagement of the locking portion 41 with the notch 40. In this manner, the main body 1 is formed so as to be able to be assembled into a triangular prism shape. Of the three faces 11, 12, and 13 of the main body, two faces 11 and 12 are provided with holding portions 3U and 3D at the top and bottom ends, respectively, as will be described later, so that the overall shape is a slightly irregular rectangle.

[0022] Opening 10 of main body 1 is formed across two of three faces 11, 12, and 13 of main body 1. In this case, opening 10 is formed between two consecutive faces 11 and 12 of the three faces 11, 12, and 13, at a lower side at a height corresponding to body portion A01 of ampoule A0, with opening 10 spanning the top between two faces 11 and 12 as its center, in a size and shape that allows for display of some or all of the various information L about the liquid medicine attached to body portion A01 of ampoule A0. Here, opening 10 is formed as a rectangle that is long in the width direction of two faces 11 and 12 of main body 1 and is large enough to display at least the name of the liquid medicine, expiration date, etc. printed on label L1.

[0023] The holding portion 2 is formed so as to be bendable from both side edges of the opening 10 of the main body 1 toward the inner surface of the triangular prism shape of the main body 1 into a V-shaped cross section. In this case, the holding portion 2 is formed so as to be continuous between both side edges of the opening 10 of the main body 1 and bendable toward the remaining surface 13 of the main body 1 facing the opening 10 into a V-shaped cross section so as to inscribe the body A01 of the ampoule A.

[0024] The top and bottom pressing portions 3U and 3D are formed at both ends of the main body 1 so as to be foldable toward the inner surface that is the inside of the triangular prism shape of the main body 1. In this case, each pressing portion 3U and 3D has M-shaped convex portions 31 and 32 formed continuously at both end edges (positions that will become both end edges) of the two faces 11 and 12 of the main body 1, and also has folds 104 and 105 formed obliquely in a V-shape overall, formed inside (inside) both end edges of these two faces 11 and 12 from near the apex (fold 101) between the two faces 11 and 12 toward the intersection of both end edges of the two faces 11 and 12 and the apex (folds 102 and 103) between the two faces 11 and 12 and the remaining face 13. That is, convex portions 31, 32 are formed in a predetermined triangle on both end edges of each of the two faces 11, 12, and folds 104, 105 are formed at both ends of each of the two faces 11, 12, slightly inward from the both end edges and near the apex (fold 101) between the two faces 11, 12, toward the apex (folds 102, 103) opposite the apex (fold 101) between the two faces 11, 12, on both end edges of each of the two faces 11, 12. Thus, each of the top and bottom pressing portions 3U, 3D is provided in each portion defined by the outer edges of each triangular convex portion 31, 32 on both ends of the two faces 11, 12 and each of the folds 104, 105. In this way, two pressing portions 31, 32 are formed on both ends of each of the two faces 11, 12, and these pressing portions 31, 32 are each folded toward the inner surface of the main body 1 via each crease 104, 105, so that the adjacent edges 311, 321 (see Figure 2) of each pressing portion 31, 32 are butted together and folded into a convex V-shape toward the inside of the main body 1.

[0025] In addition, the main body 1, holding portion 2, and top and bottom pressing portions 3U, 3D of this pack P are integrally formed from a single blank sheet S made of so-called paperboard, as shown in Figures 2 to 4.

[0026] The blank sheet S comprises a two-sided main body portion S11-S12 consisting of two surfaces S11 and S12 for forming two of the three surfaces 11, 12, 13 of the triangular prism shape of the main body 1, a one-sided main body portion S13 consisting of two surfaces S13L and S13R connected to both sides of the two-sided main body portion S11-S12 and for forming the remaining surface 13 of the three surfaces 11, 12, 13 of the triangular prism shape of the main body 1, and two pressing portion shaped portions S3U and S3D connected in a convex manner to both end edges (shown as (upper edge) and (lower edge) in Figure 2) of the two-sided main body portion S11-S12, respectively, for forming part of the top and bottom pressing portions 3U and 3D. Between the two surfaces S11 and S12 of the two-surface main body portion S11-S12 and between the two surfaces S11 and S12 of the two-surface main body portion S11-S12 and the two surfaces S13L and S13R of the one-surface main body portion S13, respectively, there are provided a central fold line F101 forming a central fold line 101 and side fold lines F102 and F103 forming side fold lines 102 and 103, which are provided to allow the two-surface main body portion S11-S12 and the one-surface main body portion S13 to be assembled into a triangular prism shape. The two-surface main body portion S11-S12 has a fold line F101 between its two faces S11 and S12, and extends obliquely from a predetermined position inside the two-surface main body portion S11-S12 relative to both ends (upper and lower edges) of the two-surface main body portion S11-S12 toward the boundaries between the two faces S11 and S12 of the two-surface main body portion S11-S12 and the two faces S13L and S13R of the one-surface main body portion S13 on both ends (upper and lower edges) of the two-surface main body portion S11-S12, forming an overall V-shape, with both ends (upper and lower edges) of the two-surface main body portion S11-S12 being the remainders of the top and bottom pressing portions 3U and 3D (shown as (remaining portion) in FIG. 2).) as two slits C104, C105 forming two folds 104, 105 that are provided so as to be able to fold together with a part of each pressing portion S3U, S3D toward the inner surface of the two-surface main body portion S11-S12, and one pair of upper and lower slits C106 that are provided in the two-surface main body portion S11-S12 so as to be able to form one pair of upper and lower opening edge portions of the opening 10 in parallel on both sides of the fold line F101 in the center between the two surfaces S11, S12 of the two-surface main body portion S11-S12. The other pair of notches C107 extend discontinuously between the left and right side ends of the one pair of notches C106 and form folds 107 that are arranged so that the other pair of opening edges on the left and right of the opening 10 can be formed and so that the holding portion 2 can be formed between the other pair of opening edges, and a central notch C108 extends in the center between the other pair of notches C107 in parallel to the other pair of notches C107 and forms folds 108 that are arranged so that the holding portion 2 can be folded into a V-shaped cross section.

[0027] In this case, the two-sided main body portion S11-S12 has two sides separated by a central fold line F101, and each of the two sides S11, S12 has a basic shape of a vertically long rectangle with a width greater than the outer diameter of the body portion A01 of the ampoule A0 and a height greater than the height of the entire ampoule A0. Note that, since parts of the two presser portion shaped portions S3U, S3D are formed at both end edges of the two-sided main body portion S11-S12 (strictly speaking, at the positions that become both end edges (upper end edge, lower end edge) (positions indicated by virtual lines (two-dotted chain lines) in Figure 2)), each of the two sides S11, S12 forms a slightly irregular rectangle as a whole. In addition, the central fold line F101 of the main body two-sided shaped portion S11-S12 is formed concavely from the outer surface to the inner surface of the main body two-sided shaped portion S11-S12 between a pair of V-shaped notches C104, C105, and is formed as a series of notches between each notch C104, C105 and both end edges of the main body two-sided shaped portion S11-S12.

[0028] In this case, the two surfaces S13L, S13R of the single-surface main body portion S13 are each formed into a rectangle of the same size as the two surfaces S11, S12 of the two-surface main body portions S11-S12. Similarly to the central fold line F101, the fold lines F102, F103 on both sides between the two-surface main body portions S11-S12 and each of the single-surface main body portions S13 are each formed into a concave shape from the outer surface toward the inner surface of the single-surface main body portion S13. In this way, the two surfaces S13L, S13R of the single-surface main body portion S13 are each formed to a size that allows them to overlap with each other when assembled together with the two-surface main body portions S11-S12 into a triangular prism shape, and the two surfaces S13L, S13R of the single-surface main body portion S13 are overlapped and fixed.

[0029] In this case, each of the two pressing portion shapes S3U, S3D has M-shaped convex portions 31, 32 formed continuously at both end edges of the two-sided main body portion S11-S12 (strictly speaking, at positions that will become both end edges (upper end edge, lower end edge) (positions shown by imaginary lines (two-dotted chain lines) in FIG. 2)), and a predetermined triangle is formed at both end edges of each of the two faces S11, S12 of the two-sided main body portion S11-S12. Here, the predetermined triangle is formed by bending each of the pressing portion shapes S3U, S3D toward the inner surface of the main body 1 via each pair of notches C104, C105, so that each of the pressing portion shapes S3U, S3D has its adjacent edges 311, 321 abutting or approaching each other, forming a triangle that can be folded into a convex V-shape toward the interior of the two-sided main body portion S11-S12. Each pair of notches C104, C105 is formed on both ends of the two-sided main body portion S11-S12, starting from a predetermined position within the plane (inner) of the two-sided main body portion S11-S12 near the apex between the two faces S11, S12 of the two-sided main body portion S11-S12, further inward than the two end edges (strictly speaking, the positions indicated by the imaginary lines (dashed two-dotted lines) in Figure 2) of these two faces S11, S12, and extending diagonally toward the intersection of the two end edges (upper and lower edges) of the two-sided main body portion S11-S12 and the apex between the two faces S13L, S13R of the one-sided main body portion S13, forming a series of notches in a V-shape overall. In this way, each pair of slits C104, C105 is provided so that both end sides of the two-surface main body portion S11-S12 can be folded together with a part of each pressing portion S3U, S3D as the remaining part of each pressing portion S3U, S3D toward the inner surface of the main body 1. Thus, with the two pressing portion portions S3U, S3D each folded and assembled into a triangular prism shape by the two-surface main body portion S11-S12 and the one-surface main body portion S13, their adjacent edges are butted together and folded toward the inside of the triangular prism, forming a triangle so that both ends of the triangular prism can be closed.

[0030] In this case, the opening 10 of the two-faced main body portion S11-S12 is provided on the lower side of the two-faced main body portion S11-S12, corresponding to the various information L, i.e., the label L1, to be affixed to the body portion A01 of the ampoule A0. One pair of upper and lower slits C106 and the other pair of left and right slits C107 for forming this opening 10 are each formed as a series of linear slits. In this manner, the holder-shaped portion S2 is cut out within this opening 10, and both the left and right sides are left connected to the two-faced main body portions S11-S12. Then, in the center between the left and right sides of this holder-shaped portion S2, i.e., in the center between the other pair of slits C107, a central slit C108 is formed as a perforated line parallel to the other pair of slits C107, so that this holder-shaped portion S2 can be folded into a V-shaped cross section.

[0031] In this case, a locking portion-shaped portion S41 protrudes from one (in this case, S13R) of the two surfaces S13L, S13R of the single-surface main body portion S13 on the side opposite the two-surface main body portions S11-S12, and a notch S40 is provided between the other (in this case, S13L) of the two surfaces S13L, S3R of the single-surface main body portion S13 and the two-surface main body portions S11-S12 so that the locking portion-shaped portion S41 can engage with the locking portion-shaped portion S41. The locking portion-shaped portion S41 protrudes in a trapezoidal shape from the center of the side of one (S13R) of the single-surface main body portion S13. A fold line F109 is provided between this locking portion-shaped portion S41 and one (S13R) of the single-surface main body portion S13. The fold line F109 is formed across the width of the locking portion-shaped portion S41, concave from the outer surface of the locking portion-shaped portion S41 toward the inner surface. The slit S40 is formed by cutting in the shape of a square bracket in the center of the fold line F102 between the other side (S13L) of the main body one-surface portion S13 and the main body two-surface portion S11-S12. In this way, the two surfaces S13L and S13R of the main body one-surface portion S13 are fixed by the engagement between the locking portion-shaped portion S41 and the slit S40. As a result, the locking portion-shaped portion S41 forms the locking portion 41 as the fixing portion 4, and the slit S40 forms the slit 40 as the fixing portion 4.

[0032] In this way, the blank sheet S is composed of these shaped portions, fold lines, and cuts.

[0033] In this way, this pack P surrounds the ampoule A0 by the main body 1 at the three corners of the triangular prism shape of the main body 1 via a buffer space 100, and holds the ampoule A0 by the holding part 2 at the four corners of the holding space 20, which is defined as a rectangle in a plan view between the holding part 2 and the two faces 11 and 12 of the main body 1, via a buffer space 200, and fixes the ampoule A0 inside the main body 1 with a pressing part 3U on the top side and a pressing part 3D on the bottom side.

[0034] Figure 5 shows an example of how to use the pack P. Before use, the pack P remains in the form of a blank sheet S, i.e., in sheet form, and is not bulky, so even a large number of packs P can be stored compactly in a drawer or on a shelf in a hospital pharmacy, etc. By storing them in this way, the pack P can be easily removed from the storage location and used to package ampoules A each time it is used.

[0035] As shown in Figure 5(1), first, in order to assemble the main pack P from the blank sheet S of the main pack P, folds 101-109 are made in the blank sheet S. In this case, first, the two-sided main body portion S11-S12 of the blank sheet S is folded around the central fold line F101, and the inner faces of the two sides S11 and S12 of the two-sided main body portion S11-S12 are aligned, and a fold line 101 is made along the central fold line C101. Furthermore, as the two-face main body portion S11-S12 is folded, a holding portion 2 is formed from between one pair of upper and lower notches C106 formed between the two faces S11, S12 of the two-face main body portion S11-S12 to the other pair of left and right notches C107, and this holding portion 2 protrudes inward in a V-shape between the two faces S11, S12 of the two-face main body portion S11-S12 via the central notch C108 and is folded. As a result, folds 107, 108 are made along the other pair of left and right notches C107 and the central notch C108.

[0036] Next, the inner surfaces of the second surfaces S13L, S13R of the first main surface portion S13 are folded toward the inner surfaces of the second main surface portions S11-S12 around fold lines F102, F103 on both sides between the second main surface portion S11-S12 and the first main surface portion S13 of the blank sheet S, and the inner surfaces are brought together to form creases 102, 103 on the fold lines F102, F103 on both sides. Then, the locking portion portion S41 is folded inward around fold line F107 between one side of the first main surface portion S13 (S13R) and the locking portion portion S47, and the inner surfaces of the one side of the first main surface portion S13 (S13R) and the locking portion portion S41 are brought together to form fold line F109 between the first main surface portion S13 and the locking portion portion S41.

[0037] In this way, the entire blank sheet S is folded and pressurized, and creases are firmly made along each fold line. After folding the blank sheet S in this way, when the pressure is released, the restoring force of the paperboard causes the blank sheet S to unfold with creases made along each fold line, as shown in Figure 5 (2), and the two sides 11 and 12 of the main body 1 are formed from the two-side main body shaping portions S11-S12, and the holding portion 2 is formed from the holding portion shaping portion S2 between the inner surfaces of the two sides 11 and 12 of the main body 1, and two sides S13L and S13R for forming the remaining side 13 of the main body 1 are extended outward from the one-side main body shaping portion S13 on both sides of the two sides 11 and 12 of the main body 1.

[0038] Next, as shown in Figure 5 (2), the pressing portion shaped portion S3D on the bottom side of the main body 1 is raised to raise the bottom. In this case, the inner surface of the bottom side pressing portion S3D is bent toward the inner surface of the main body 1 via the notches C104 and C105 on the lower end side of the main body 1, and the bottom side pressing portion S3D is raised into a convex V-shape facing inward of the main body 1 between the two surfaces 11 and 12 of the main body 1. This forms the bottom side pressing portion 3D at the lower part of the inner surfaces of the two surfaces 11 and 12 of the main body 1. In this way, the two surfaces 11 and 12 of the main body 1 are assembled into the two surfaces 11 and 12 of a triangular prism shape, the holding portion 2 has a V-shape in planar cross section, and the bottom side pressing portion 3D has an inverted V-shape in side cross section.

[0039] In this state, ampoule A is packaged as shown in FIG. 5(3). First, ampoule A is inserted from the top side into the holder 2 between the two surfaces 11 and 12 of the main body 1, and the bottom of ampoule A is placed on and abutted against the bottom-side retainer 3D. When holding ampoule A in the holder 2, the label L1 on the periphery of ampoule A, particularly the name of the liquid medicine and expiration date, is oriented toward the opening 10 of the main body 1. Next, the top-side retainer S3U of the main body 1 is raised toward the bottom-side retainer 3D. In this case, the top-side retainer S3U is folded toward the inner surface of the main body 1 via a pair of notches C104 and C105 at the top end of the main body 1, and the top-side retainer S3U is folded toward the inside of the main body 1 between the two surfaces 11 and 12 of the main body 1, forming a convex V-shape toward the inside of the main body 1. As a result, a top-side pressing portion 3U having a V-shaped cross section is formed on the upper inner surfaces of the two faces 11 and 12 of the main body 1. The top of the ampoule A is pressed down from above by this top-side pressing portion 3U.

[0040] The two surfaces 11, 12 of the main body 1 are then closed and fixed with the remaining surface 13. In this case, the two surfaces on either side of the two surfaces 11, 12 of the main body 1, i.e., the two surfaces S13L, S13R of the main body surface shaped portion S13 of the blank sheet S, are overlapped with one surface S13L that does not have the locking portion shaped portion S41 on the inside and the other surface S13R that has the locking portion shaped portion S41 on the outside, to close the two surfaces 11, 12 of the main body 1. Then, as shown in Figures 5(4-1) and (4-2), the locking portion 41 of the other surface S13R that forms the remaining surface 13 is inserted into the slit 40 between one of the two surfaces 11, 12 of the main body 1 and the surface S13L that forms the remaining surface 13, and the remaining surface 13 is fixed between the two surfaces 11, 12 of the main body 1. In this way, the pack P is assembled into a triangular prism shape, as shown in FIG. 5(5), and the ampoule A is housed inside the pack P.

[0041] When using this pack P in this way, all that is required is to assemble the blank sheet S of the pack P into a triangular prism shape along the fold lines and slits, insert the ampule A into the holder 2 inside the main pack P, press the ampule A with the top and bottom presser sections 3U and 3D, and secure the pack P by engaging the locking section 41 with the slit 40, thereby easily packaging the ampule A in the pack P. The ampule A is then embraced and surrounded by the three surfaces 11, 12, and 13 of the triangular prism shape of the main body 1 of the pack P and the double structure of the two V-shaped surfaces of the holder 2, and is secured by the presser sections 3U and 3D on the top and bottom, so that the ampule A can be securely held within the main pack P. In this way, the ampoule A in this pack P is held via a buffer space 100 formed at the three corners of the triangular prism shape of the main body 1, and further via a buffer space 200 formed at the four corners of a holding space 20 that is rectangular in plan view and defined within the main body 1 between the two faces 11, 12 of the main body 1 and the holding part 2, thereby ensuring that the ampoule A is protected from external impacts.

[0042] Therefore, this pack P is extremely useful in situations where, for example, at a university hospital, ampoules A dispensed for hospitalized patients are placed in a medicine bag for each patient, and these medicine bags are then collectively placed in a basket or tray, transported within the hospital, and distributed to each patient. That is, ampoules A can be easily packaged in this pack P. By packaging ampoules A in this pack P, ampoules A can be reliably protected, and therefore ampoules A can be prevented from being damaged even if they are subjected to a strong impact, such as being dropped during transportation or handling during transportation.

[0043] After use, the pack P is already unfolded when the ampoule A is removed from the pack P, so it can be simply unfolded and stretched out, and even if there are many packs P, they do not become bulky and can be easily disposed of.

[0044] As described above, this main pack P includes a main body 1 assembled into a triangular prism shape and containing an ampoule A, a holding section 2 inserted into the main body 1 to hold the ampoule A contained within the main body 1, and top and bottom pressing sections 3 for pressing the top and bottom of the ampoule A contained within the main body 1. In this way, the ampoule A is embraced and surrounded by the double structure of the three faces 11, 12, and 13 of the triangular prism shape of the main body 1 of this pack P and the two V-shaped faces of the holding section 2, and is pressed and fixed by the top and bottom pressing sections 3U and 3D, so that the main body 1 surrounds the ampoule A at the three corners of the triangular prism shape of the main body 1 via buffer spaces 100, and the holding section 2 holds the ampoule A at the four corners of a holding space 20 that is rectangular in plan view and defined between the holding section 2 and the two faces 11 and 12 having the opening 10 of the main body 1 via buffer spaces 200.

[0045] Therefore, when using ampoules A at a medical institution, the ampoules A can be packaged in this pack P with a simple assembly process and easily protected from external forces when transporting the ampoules A within the medical institution or from the medical institution to an external location. In particular, the triangular prism shape of this pack P allows the pack P to firmly hold and protect the ampoules A, as described above. Furthermore, the triangular prism shape of this pack P allows for compact storage without adding bulk when placed in a medicine bag, making it ideal for transporting and handling the ampoules A during transport. Furthermore, the pack P has an opening 10 in the main body 1, and the label L1 of the ampoules A faces this opening 10, allowing various information L regarding the medicinal liquid to be displayed. Therefore, various information L regarding the medicinal liquid in the ampoules A can be checked at any time. Furthermore, because the pack P can be easily made using only paper materials such as cardboard without the need for glue, the pack P can be provided relatively inexpensively. Furthermore, before use, the pack P is in sheet form, so even if there are many of them, they do not take up much space, and can be stored in a space-saving manner at the place where the pack P is used. After use, the pack P can be unfolded into a sheet form, so in this case too, it does not take up much space and can be easily disposed of.

[0046] Furthermore, this pack P has the following advantages due to the following configuration.

[0047] The main body 1, the holding portion 2, and the top and bottom pressing portions 3U, 3D are formed from a single blank sheet S made of cardboard. As described above, this blank sheet S has two-sided main body portions S11-S12, a two-sided one-sided main body portion S13, and two pressing portion portions S3U, S3D. The blank sheet S has a central fold line F101 and fold lines F102, F103 on both sides between the two-sided main body portions S11-S12 and the two-sided main body portions S11-S12 and the one-sided main body portion S13, respectively. The two-sided main body portions S11-S12 have a pair of notches C104, C105 at the top and bottom ends, a pair of notches C106 at the top and bottom, a pair of notches C107 at the other left and right, and a central notch C108. The blank sheet S is made up of only this structure, and the pack P can be realized with a simple structure using paper material.

[0048] In this case, the two pressing portions S3U, S3D are folded and assembled into a triangular prism shape by the two-surface main body portion S11-S12 and the one-surface main body portion S13, and then the adjacent edges 311, 321 are butted together and folded into the triangular prism shape, forming a triangle so that both ends of the triangular prism shape can be closed.As a result, even with the simple structure of this pack P, the ampoule A can be more reliably held within this pack P and more reliably protected.

[0049] In this case, the two surfaces S13L and S13R of the main body single-surface shaped portion S13 are each formed to the same size as one surface on either side of the central fold line F101 of the main body two-surface shaped portion S11-S12, and the two surfaces S13L and S13R of the main body single-surface shaped portion S13 are overlapped and fixed, so that the main body 1 can be easily and reliably formed into a triangular prism shape, and even with the simple structure of this pack P, the ampule A can be more reliably held within this pack P and more reliably protected.

[0050] Furthermore, in this case, a locking portion shaped portion S2 protrudes from the side of one of the main body one-surface shaped portions S13 (here, S13R) opposite the main body two-surface shaped portion S11-12, and a notch S40 is provided between the other of the main body one-surface shaped portion S13 (here, S13L) and the main body two-surface shaped portion S11-12 so that the locking portion shaped portion S2 can engage with it, and one of the main body one-surface shaped portions S13 (S13R) and the other (S13L) are fixed by the engagement of the locking portion 41 with the notch 40, so that the main body 1 can be easily and reliably formed into a triangular prism shape and fixed, and even with the simple structure of this pack P, the ampoule A can be more reliably held within this pack P and more reliably protected.

[0051] In this embodiment, the main pack P and blank sheets S can be modified as follows.

[0052] In the main body pack P, the remaining one surface 13 of the triangular prism shape of the main body 1 is formed by connecting a single-surface main body portion S13 to each side of the two-surface main body portions S11-S12, as shown in the blank sheet in FIG. 2, to form the remaining one surface 13 of the triangular prism shape of the main body 1, and is composed of two surfaces S13L and S13R. However, a single-surface main body portion consisting of a single surface for forming the remaining one surface 13 of the triangular prism shape of the main body 1 may be connected to one side of the two-surface main body portions S11-S12. In this case, this single-surface main body portion is fixed to one of the two-surface main body portions connected to it. The fixing method may be any method, such as providing one or more locking protrusions on one of the connecting ends between the single-surface main body portion and one or more locking recesses on the other, and fixing the single-surface main body portion to one of the two-surface main body portions by engagement between the locking protrusions and the locking recesses, or the single-surface main body portion and one of the two-surface main body portions may be fixed via adhesive tape. Furthermore, similar to the above embodiment, one or more locking portions may be provided on one of the connection ends between the main body one-surface shaped portion and one of the main body two-surface shaped portions, and one or more notches may be provided on the other, and the two may be fixed by engagement between these locking portions and notches. This also provides the same effects as those of the above embodiment.

[0053] An opening 10 is provided between the two surfaces 11, 12 of the main body 1 of the pack P to expose information L about the medicinal liquid attached to the circumferential surface of the ampoule, but this opening 10 does not have to be provided. In this case, information about the medicinal liquid may be attached by label, printing, or handwriting to an appropriate position on the three surfaces 11, 12, and 13 of the pack P, if necessary. This also provides the same effects as those of the above embodiment.

[0054] In this embodiment, an ampoule containing an injection agent is used as an example of a medicinal liquid container for storing a medicinal liquid, but the present invention can also be applied to various ampoules and vials containing other medicinal liquids, and in this case, it goes without saying that the same effects as those of the above embodiment can be achieved.
