Summary of the Invention
Problems to be Solved by the Invention
[0004] However, if the size of the bottle containing the drug is increased to increase the drug's capacity, or if the size and shape of the bottle into which the drug disperser is inserted is changed, arranging the two bottles inside the blister pack so that their axes are aligned would require a change in the size of the blister pack. This would necessitate a change in the box containing the blister pack, increasing the cost of packaging the drug disperser. Furthermore, a larger box would reduce transportation efficiency and increase transportation costs. Additionally, retail shelves have height limitations, and increasing the box height would make it impossible to display the product in stores. Therefore, in reality, it is impossible to significantly increase the box height. The present invention was devised in view of the above circumstances, and aims to provide a blister pack housing structure for two bottles that can be distributed to the market without changing the rectangular box, even when the size or shape of the bottle into which the volatile substance is inserted is changed, or when the bottle containing the drug is enlarged in order to increase the amount of drug. [Means for solving the problem]
[0005] To achieve the above objective, one embodiment of the present invention provides a two-bottle storage structure using a blister pack that stores a first bottle and a second bottle, each having a body and a neck, in a separated state, wherein the blister pack is provided with a first storage section for storing the first bottle and a second storage section for storing the second bottle, and when viewed from above with the first bottle and the second bottle respectively stored in the first and second storage sections, the axial direction of at least one of the first bottle and the second bottle is inclined with respect to the length direction of the blister pack, and when viewed from the width direction perpendicular to the length direction of the blister pack, the neck of one of the first bottle and the bottom portion of the body of the other bottle overlap in the middle of the length direction of the blister pack. Furthermore, in one embodiment of the present invention, a cap is attached to the neck portion of the first bottle, and when the first bottle and the second bottle are housed in the first and second storage portions, respectively, and viewed from above, the axial directions of the first bottle and the second bottle are inclined in substantially the same direction with respect to the length direction of the blister pack, and when viewed from the width direction perpendicular to the length direction of the blister pack, the cap of the first bottle and the portion of the body of the second bottle near the bottom overlap in the middle of the length direction of the blister pack. Furthermore, in one embodiment of the present invention, a shoulder portion is interposed at the boundary between the neck portion and the body portion of the first bottle and the second bottle, and when viewed from the width direction perpendicular to the length direction of the blister pack, the shoulder portion of the first bottle and the bottom portion of the body portion of the second bottle are separated in the middle of the length direction of the blister pack. Furthermore, one embodiment of the present invention is characterized in that, when the first bottle is housed in the first storage section, the axial direction of the first bottle is inclined vertically with respect to the longitudinal direction of the blister pack such that the neck portion is positioned above the body portion. Furthermore, in one embodiment of the present invention, the body of the second bottle has a thickness and a width greater than the thickness, the surface located in one of the two directions in the thickness direction of the body of the second bottle is the front of the second bottle, and when the second bottle is housed in the second storage section, the width direction of the body of the second bottle is inclined with respect to the width direction of the blister pack to such an extent that the front can be seen from above the blister pack, and the front is oriented diagonally upward. Furthermore, in one embodiment of the present invention, the width of the body of the second bottle is formed to gradually decrease from the upper end to the bottom of the body, and the thickness of the body is formed to be greatest in the center in the width direction and gradually decreases as it moves away from the center in the width direction, and when the second bottle is housed in the second storage section, the axial direction of the second bottle is inclined vertically with respect to the length direction of the blister pack such that the neck is located above the body, and in a plan view, the cap portion of the second bottle near the body and the portion of the second bottle near the cap and closer to the bottom of the body overlap. Furthermore, in one embodiment of the present invention, the blister pack has a rectangular shape in plan view, and the blister pack has an upper end wall extending along the four sides of the rectangle in plan view, a side wall extending downward from the upper end wall, and an intermediate wall extending inward from the side wall at the midpoint of the height of the blister pack, the first storage section is configured to include a first body recess, a first shoulder recess, and a cap recess provided in the intermediate wall for accommodating the body, shoulder, and cap of the first bottle, and the second storage section is configured to include a second body recess, a second shoulder recess, and a neck recess provided in the intermediate wall for accommodating the body, shoulder, and neck of the second bottle. Furthermore, in one embodiment of the present invention, the first shoulder recess has a first shoulder wall that abuts against the shoulder of the first bottle and whose upper end is connected to the intermediate wall, and the second body recess has a second bottom wall that abuts against the bottom of the body of the second bottle and whose upper end is connected to the intermediate wall, and a convex portion is provided on the neck side of the first bottle when viewed from above, formed by the portion of the intermediate wall to which the first shoulder wall is connected and the portion of the intermediate wall to which the second bottom wall is connected, which are located on the inside in the width direction of the blister pack, and a convex portion is provided on the convex portion and the convex portion is formed as a first reinforcing wall portion with increased rigidity. Furthermore, in one embodiment of the present invention, with the first bottle housed in the first storage section, the cap is positioned toward one of the side walls located on both sides of the blister pack in the width direction, the portion of the one side wall facing the cap constitutes the portion of the cap recess on one side of the blister pack in the width direction, the portion of the one side wall facing the cap has irregularities, and the portion of the one side wall facing the cap is formed as a second reinforcing wall portion with increased rigidity. [Effects of the Invention]
[0006] According to one embodiment of the present invention, when viewed from above, the axial directions of the first bottle and the second bottle are inclined in approximately the same direction with respect to the length direction of the blister pack. When viewed from the width direction of the blister pack, the cap of the first bottle and the bottom part of the body of the second bottle overlap in the middle of the length direction of the blister pack. Therefore, even if the axial length of the first bottle is increased, the first and second bottles can be housed in the blister pack while separated from each other without changing the width, length, or height of the blister pack. As a result, it can be used without changing the size of the blister pack or the shape and size of the box that houses the blister pack, which is advantageous in reducing the cost increase for packaging the drug disperser, as well as in reducing the cost increase for transportation and is also advantageous for display in stores. Furthermore, since the shoulder of the first bottle and the bottom of the body of the second bottle are separated, it is advantageous to house the first and second bottles separately in the blister pack without changing the size of the blister pack. Furthermore, the axial direction of the first bottle is inclined vertically with respect to the length direction of the blister pack so that the neck is positioned above the body. This is advantageous in storing the bottles with a greater distance between the cap of the first bottle and the bottom of the body of the second bottle, which helps prevent collision between the cap of the first bottle and the bottom of the body of the second bottle in the event of an impact, thus preventing damage to the cap. Furthermore, when the second bottle is housed in the second storage section, the width of the body of the second bottle is inclined relative to the width of the blister pack to such an extent that the front is visible from above the blister pack, and the front is angled upwards. Therefore, even if the width of the body of the second bottle is increased, the second bottle can be housed without changing the size of the blister pack or box, which is advantageous in suppressing cost increases for the packaging of the chemical disperser. Furthermore, this arrangement is advantageous in that the cap of the first bottle and the bottom of the body of the second bottle are housed further apart, preventing collision between the cap of the first bottle and the bottom of the body of the second bottle in the event of an impact, and thus preventing damage to the cap. Furthermore, when the second bottle is housed in the second housing, the axial direction of the second bottle is inclined vertically with respect to the length of the blister pack such that the neck is positioned above the body. This is advantageous in housing the bottles with a greater distance between the cap of the first bottle and the bottom of the body of the second bottle, which helps prevent collision between the cap of the first bottle and the bottom of the body of the second bottle in the event of an impact, thus preventing damage to the cap. Furthermore, when viewed from above, the cap area of the second bottle near the second body overlaps with the area near the cap near the bottom of the second bottle's body. This is advantageous for enlarging both the first and second bottles without changing the shape or size of the box, and is beneficial for keeping costs down regarding the packaging of the chemical disperser. Furthermore, according to this embodiment, a blister pack storage structure can be obtained that can store the first bottle and the second bottle separately by a simple configuration in which the blister pack is composed of an upper end wall, a side wall and an intermediate wall, and the intermediate wall is provided with a first storage section consisting of a first body recess, a first shoulder recess and a cap recess, and a second storage section consisting of a second body recess, a second shoulder recess and a neck recess. Furthermore, according to this embodiment, a convex portion is provided on the neck side of the first bottle when viewed from above, formed by the portion of the intermediate wall to which the upper end of the first shoulder wall, located inward in the width direction of the blister pack from the cap recess, is connected, and the portion of the intermediate wall to which the second bottom wall is connected. This convex portion is formed as a first reinforcing wall portion with increased rigidity of the intermediate wall. Therefore, when the blister pack containing the first and second bottles is placed in a box, it is possible to prevent the blister pack from twisting due to impact when dropped with the side of the box facing downwards on the side where the cap is located. Therefore, the blister pack twists, which is advantageous in preventing damage to the cap caused by the bottom of the second bottle's body colliding with it. Furthermore, according to this embodiment, the portion of the side wall facing the cap on the side where the cap recess is located is formed as a second reinforcing portion with increased rigidity of the side wall. Therefore, when the blister pack containing the first and second bottles is placed in a box, if the box is dropped with the side of the box facing downwards, the second reinforcing portion functions as a cushioning material to mitigate the impact. This is advantageous in preventing damage to the cap caused by the corner between the tip and outer surface of the cap hitting the floor. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0008] Next, a blister pack 10 according to an embodiment of the present invention will be described. First, let's explain the chemical disperser housed in the blister pack 10. The chemical disperser comprises a bottle that airtightly and liquid-tightly houses liquid chemicals such as volatile fragrances, insect repellents, and insecticides, multiple rod-shaped chemical dispersers 14, and a bottle into which the chemical is injected and into which the multiple rod-shaped chemical dispersers are inserted. In the following explanation, the bottle that contains the drug in an airtight and liquid-tight manner will be referred to as the first bottle 12 (see Figure 25), and the bottle into which the multiple rod-shaped drug volatilizers 14, shown by dashed lines in Figure 26(A), are inserted will be referred to as the second bottle 16 (see Figure 26). The first bottle 12 and the second bottle 16 are housed in a blister pack 10, which, along with several rod-shaped chemical volatilizers 14, are housed in a rectangular box 18 (see Figures 15, 17, and 19) and distributed to the market. Purchasers of the chemical volatilizer remove the blister pack 10 and the several rod-shaped chemical volatilizers 14 from the box 18, remove the first bottle 12 and the second bottle 16 from the blister pack 10, pour the chemical from the first bottle 12 into the second bottle 16, insert the several rod-shaped chemical volatilizers 14 into the second bottle 16, and use the device by volatilizing the chemical from the parts of the several rod-shaped chemical volatilizers 14 that protrude upward from the second bottle 16. The multiple rod-shaped chemical volatilizers 14 are made of wood, rattan, bamboo, resin, paper, etc. The first bottle 12 and the second bottle 16 are made of glass or synthetic resin and are transparent, translucent, or opaque.
[0009] As shown in Figure 25, the first bottle 12 comprises a first body portion 1202, a first neck portion 1204 that rises from the first body portion 1202, and a cylindrical cap 1206 that is detachably attached to the first neck portion 1204. The first neck portion 1204 and the first body portion 1202 are both cylindrical in shape. The bottom portion 1208 of the first body portion 1202, which is located opposite the first neck portion 1204, is circular. The portion of the first body portion 1202 closer to the first neck portion 1204 forms a first shoulder portion 1210, whose cross-sectional area gradually decreases as it approaches the first neck portion 1204. The shoulder portion of the bottle refers to the boundary between the neck portion and the body portion, and the shoulder portion may be formed by a plane perpendicular to the axis of the body portion, and its shape is arbitrary.
[0010] As shown in Figures 26(A) to (D), the second bottle 16 comprises a second body portion 1602 and a second neck portion 1604 that rises from the second body portion 1602. As shown in Figure 26(B), the second body portion 1602 has a thickness T1 and a width W1 that is greater than the thickness T1, and when viewed from above, it has an elongated shape. One side of the second body section 1602, located in the direction of thickness T1, is the front 1602A, and the other side is the back 1602B. Stickers printed with patterns, characters, product names, manufacturer names, etc., are affixed to the front 1602A and back 1602B, respectively. As shown in Figure 26(A), when the second body section 1602 is viewed from the front, the width W1 of the second body section 1602 gradually decreases as it approaches the bottom section 1608 from the top end. As shown in Figure 26(B), the thickness T1 of the second body 1602 is formed such that it is largest in the center in the width W1 direction and gradually decreases as it moves away from the center in the width W1 direction. The portion of the second torso 1602 closer to the second neck 1604 is the second shoulder 1610, in which the cross-sectional area gradually decreases as it approaches the second neck 1604. As shown in Figure 26(D), the bottom 1608 of the second body portion 1602, which is located opposite the second neck portion 1604, is circular in shape. As shown in Figure 26(A), the second neck portion 1604 is cylindrical in shape, with a thick-walled annular portion 1604A formed at its tip, and the inside of the thick-walled annular portion 1604A is an opening 1604B into which a rod-shaped chemical volatilizer 14 is inserted.
[0011] Next, we will describe the blister pack 10 that contains the first bottle 12, the second bottle 16, and the multiple rod-shaped drug volatile particles 14. Various conventionally known synthetic resin materials can be used as the materials that make up the blister pack 10. As shown in Figures 1 and 3, the blister pack 10 has a horizontal width W2, a length L2, and a vertical height H2, is rectangular in plan view, and is sized to be able to be inserted into and removed from the inside of a rectangular box 18 (see Figures 15, 17, and 19) used during distribution, from the longitudinal direction of the box 18. Various conventionally known materials such as cardboard and synthetic resin can be used for the box 18. As shown in Figures 15, 17, and 19, the box 18 has an upper surface 1802 and a lower surface 1804 that are opposite each other in the vertical direction, a pair of end surfaces 1806 that are opposite each other in the longitudinal direction of the box 18, and a left side surface 1808 and a right side surface 1810 that are opposite each other in a direction perpendicular to the longitudinal direction of the box 18, and these surfaces are rectangular in shape. The blister pack 10 is housed inside the box 18 and is formed with a shape and dimensions that allow it to fit snugly within the rectangular contour of the box 18 without rattling, with parts of the blister pack 10 in contact with or in close proximity to each of the six sides of the rectangular box 18's interior. As shown in Figure 1, the blister pack 10 is provided with a first storage section 20 that is open at the top and accommodates the first bottle 12, and a second storage section 22 that is open at the top and accommodates the second bottle 16, arranged in the direction of the length L2 of the blister pack 10. As shown in Figure 15, the first bottle 12 and the second bottle 16 are placed in the first storage section 20 and the second storage section 22 with their axial directions approximately aligned with the length direction of the blister pack 10, and laid flat.
[0012] As shown in Figure 15, the first storage section 20 holds the first bottle 12 so that it cannot move in the axial direction and in directions perpendicular to the axial direction, with its cap 1206 facing one direction in the length L2 direction of the blister pack 10 and the bottom 1208 of the first body 1202 facing the other direction in the length L2 direction of the blister pack 10, and also stores it so that it can be removed from above. The second storage section 22 holds the second bottle 16 so that it cannot move in the axial direction and in directions perpendicular to the axial direction, with its second neck portion 1604 facing one direction in the length L2 direction of the blister pack 10 and the bottom portion 1608 of the second body portion 1602 facing the other direction in the length L2 direction of the blister pack 10, and stores it so that it can be removed from above. With the first bottle 12 and the second bottle 16 housed in the first storage section 20 and the second storage section 22 respectively, all parts of the first bottle 12 and the second bottle 16 are separated with a gap between them and not in contact. In a plan view, as shown in Figure 15, the axial directions of the first bottle 12 and the second bottle 16 are inclined in the same direction as the width W2 of the blister pack 10 with respect to the length L2 direction of the blister pack 10, and the cap 1206 of the first bottle 12 and the bottom 1608 of the second body 1602 of the second bottle 16 are located in the middle of the length L2 direction of the blister pack 10. As shown in Figures 17 and 18, when viewed from the width W2 direction of the blister pack 10, the cap 1206 of the first bottle 12 and the part of the second body 1602 of the second bottle 16 near the bottom 1608 overlap, while the first shoulder 1210 of the first bottle 12 and the bottom 1608 of the second body 1602 of the second bottle 16 are separated. As shown in Figures 15 and 17, in order to prevent damage during distribution, the first bottle 12 and the second bottle 16 are housed in the first storage section 20 and the second storage section 22, respectively, and the first bottle 12 and the second bottle 16 are located at separate points inside the inner contour of the rectangular box 18, or in other words, on the six inner surfaces of the box 18.
[0013] To explain in detail, when viewed from above, the blister pack 10 has a rectangular shape. As shown in Figures 7 to 10, the upper ends of the four sides of the rectangle have upward-facing upper end walls 24. As shown in Figures 11 to 14, a folded-over wall 26 is formed on the outer edge of the upper end wall 24, which is folded downward. Furthermore, as shown in Figures 1 and 7, an outwardly bent flange wall 2602 is provided at the lower end of the folded-over wall 26. In addition, a downward-folded side wall 28 is formed on the inner edge of the upper end wall 24. Thus, the upper ends of all four sides of the blister pack 10 have a rib shape that enhances strength and rigidity. When viewed from above, the portions of the upper end walls 24 located at the four corners of the blister pack 10, and the portions of the upper end walls 24 located on the four sides of the rectangle that follow those upper end walls 24, are provided so as to be able to abut against the top surface 1802 of the rectangular box 18 used in market distribution. The flange walls 2602 on both sides of the blister pack 10 in the width direction W2 are provided so as to be able to abut against or be close to the left side 1808 and the right side 1810 on both sides of the box 18 in the width direction. The flange walls 2602 on both sides of the blister pack 10 in the length direction L2 are provided so as to be able to abut against or be close to the end faces 1806 on both sides of the box 18 in the length direction. Therefore, within the box 18, the upper wall 24 and the folded wall 26 prevent the blister pack 10 from rattling in the width W2 direction and length L2 direction.
[0014] The lower end of the side wall 28, which extends downward from the upper wall 24, is located at a height of approximately 4 / 5 to 1 / 2 of the height H2 of the blister pack 10, depending on the location, as shown in Figures 3 and 4. As shown in Figures 7 to 10, an intermediate wall 30 is provided extending from the lower end of the side wall 28 into the contour of the blister pack 10. As shown in Figures 11 to 14, stacking ribs 32 are provided at the intermediate walls 30 located at the four corners of the blister pack 10 when viewed from above. These ribs bulge outwards from the rectangular outline of the blister pack 10, and the lower surface of the stacking ribs 32 allows for smooth stacking of the blister packs 10 without expanding them.
[0015] As shown in Figure 1, the first storage section 20 is provided in one half of the blister pack 10 in the direction of its length L2, and is open above the intermediate wall 30. As shown in Figures 17 and 18, when the first bottle 12 is laid down and stored in the first storage section 20, the axial direction of the first bottle 12 is inclined vertically with respect to the length L2 direction of the blister pack 10 such that the first neck portion 1202 and the cap 1206 are positioned above the first body portion 1204. As shown in Figure 1, the first housing section 20 is composed of a first torso recess 20A that is recessed downward from the intermediate wall 30 and accommodates approximately the lower half of the first torso section 1204, a first shoulder recess 20B that is in communication with the first torso recess 20A and accommodates approximately the lower half of the first shoulder section 1210, and a cap recess 20C that accommodates the cap 1206 (first neck section 1204).
[0016] As shown in Figures 2 and 11 to 14, the first body recess 20A comprises a cylindrical first body wall 2002 that abuts against approximately the lower half of the first body 1202 when it is laid down, a first bottom wall 2004 that can abut against the portion of the bottom 1208 of the first body 1202 excluding the upper end, and a first lower bulge wall 2006. As shown in Figures 17 and 18, the wall 2002 for the first fuselage extends to a point above approximately the lower half of the first fuselage 1202 on both sides in the width direction of the first fuselage 1202 when it is laid down. The wall 2002 for the first body comes into contact with approximately the lower half of the first body 1202 when it is laid down, thereby holding the first bottle 12 in a position relative to the blister pack 10 in a width direction perpendicular to the axial direction of the first bottle 12.
[0017] As shown in Figures 7 and 8, on both opposing sides of the upper end where the first body wall 2002 connects to the intermediate wall 30, two first body locking walls 2008 are provided at intervals along the length of the first body recess 20A, which can lock onto the first body 1202 of the contained first bottle 12 from above on both sides in the width W2 direction of the blister pack 10. As shown in Figures 15 and 21, these first body locking walls 2008 lock onto the first body 1202 of the first bottle 12, thereby maintaining the state in which the first bottle 12 is contained in the first storage section 20. Furthermore, the upper edges of all four sides of the blister pack 10 have a rib shape that enhances strength and rigidity. In addition, as shown in Figure 1, wide upper walls 24A and 24B and wide intermediate walls 30A and 30B are provided at the upper end walls 24 on both sides in the width direction of the blister pack 10 where the first body locking wall 2008 is located. This ensures that the locking force of the first body locking wall 2008 to the first body 1202, preventing the first bottle 12 from falling out of the first storage section 20 when the box 18 is dropped with its upper surface 1802 facing downwards.
[0018] As shown in Figures 2 and 11 to 14, the recess 20B for the first shoulder portion includes a wall 2010 for the first shoulder portion that can abut against approximately the lower half of the reclined first shoulder portion 1210 and is connected to the intermediate wall 30.
[0019] As shown in Figure 9, the portion of the intermediate wall 30 to which the upper end of the first shoulder wall 2010 located on the inside of the width W2 direction of the blister pack 10 is connected, and the portion of the intermediate wall 30 to which the second bottom wall 2204 (described later) is connected, form a convex portion on the first neck portion 1204 side of the first bottle 12 when viewed from above, and this convex portion is formed as the first reinforcing wall portion 2012. Specifically, a bottom wall 2012A is provided at the base of the convex portion, recessing downward from the intermediate wall 30, and an upper wall 2012B is provided at the tip of the convex portion, rising from the bottom wall 2012A to the same height as the intermediate wall 30. By providing such a convex and concave portion, as shown in Figure 21, a first reinforcing wall portion 2012 is formed in which the rigidity of the intermediate wall 30 located between the first shoulder portion 1210 of the first bottle 12 and the bottom portion 1608 of the second bottle 16 is increased. Furthermore, as shown in Figure 7, a wide intermediate wall 30C and a wide upper end wall 24C are provided at the intermediate wall 30 where the first reinforcing wall portion 2012 is provided, thereby ensuring the rigidity of the intermediate portion of the blister pack 10 in the length L2 direction, and preventing twisting of the blister pack 10 when subjected to impact.
[0020] The axial direction of the first bottle 12 is positioned by the bottom 1208 of the first body 1202 of the first bottle 12 contacting the first bottom wall 2004 shown in Figures 11 and 12, and the first shoulder 1210 of the first bottle 12 contacting the first shoulder wall 2010 shown in Figures 11 and 14. As shown in Figures 11 and 12, the first lower bulge wall 2006 is provided projecting downward at the bottom of the first body recess 20A, in the center of the first body recess 20A in both the width and length directions. The first lower bulging wall 2006 is provided so as to be able to abut against the lower surface of the rectangular box 18 used in market distribution.
[0021] As shown in Figures 1 and 7, the cap recess 20C is located in the middle of the blister pack 10 in the length L2 direction, and is positioned close to one of the side walls 28 located on both sides in the width W2 direction of the blister pack 10 (the part closer to the left side 1808 of the box 18). As shown in Figures 2 and 13, the cap recess 20C comprises a cylindrical cap wall 2014 that faces the outer circumferential surface of the laid-down cap 1206 from below, and a flat cap tip wall 2016 that rises from the tip of the cap wall 2014 and faces the tip surface of the cap 1206.
[0022] As shown in Figure 9, the cap wall 2014 is located to the side of the second body portion 1602 of the second bottle 16, which is housed in the second body portion recess 22A of the second storage section 22, near the bottom portion 1608. The portion of the cap wall 2014 located on the side of the second body portion recess 22A is provided with a curved wall 2018 that rises as it approaches the second body portion recess 22A. The upper end of this curved wall 2018 is folded downward and connected to the upper end of the second fuselage wall 2202 of the second fuselage recess 22A, and is folded downward as the second fuselage wall 2202. In other words, the upper part of the curved wall 2018 and the upper part of the second body wall 2202 form an upwardly convex first rib 2020 consisting of two wall sections. Furthermore, the end of the first rib 2020 on the side of the first shoulder recess 20B is connected to the first reinforcing wall 2012, and the end of the first rib 2020 that is separated from the first shoulder recess 20B is connected to the corner where the cap tip wall 2016 and the second body locking wall 2208 (described later) intersect. This increases the rigidity of the cap recess 20C and also prevents collision between the bottom 1608 of the second body 1602 of the second bottle 16 and the cap 1206 when subjected to impact.
[0023] Furthermore, as shown in Figure 7, the portion of one side wall 28 facing the cap 1206 where the cap recess 20C is located constitutes a cap wall 2014. This portion of the side wall 28 that constitutes the cap wall 2014 is provided with an uneven surface, and this portion of the side wall 28 that constitutes the cap wall 2014 is configured as a second reinforcing portion 2022. In other words, a second reinforcing wall section 2022 is provided at this side wall 28, consisting of a first outer wall 2022A that faces the cap 1206 from the outside in the width W2 direction of the blister pack 10, and a second outer wall 2022B that is located inward in the width W2 direction of the blister pack 10 compared to the first outer wall 2022A, thereby increasing the rigidity of this side wall 28. With the cap 1206 housed in the cap recess 20C, the corner between the tip surface and the outer surface of the cap 1206 faces the second outer wall 2022B at a point away from the second outer wall 2022B, and the outer surface of the cap 1206 is separated from the first outer wall 2022A. For example, if the left side 1808 of the box 18 falls downwards, the second reinforcing wall 2022 prevents damage to the cap 1206 from the corner between the tip surface and the outer surface of the cap 1206 colliding with the floor.
[0024] As shown in Figure 1, the second storage section 22 for accommodating the second bottle 16 is provided in the other half of the blister pack 10 in the direction of length L2, and is open above the intermediate wall 30. As shown in Figures 21 and 22, when the second bottle 16 is laid down and placed in the second storage section 22, the width W1 direction of the second body 1602 of the second bottle 16 is inclined with respect to the width W2 direction of the blister pack 10 to such an extent that the front 1602A is visible from above the second bottle 16, and the front 1602A is facing diagonally upward. Here, an inclination that allows for visibility is between 30 and 60 degrees, and in this embodiment, it is inclined at 45 degrees. As shown in Figures 17 and 18, in this embodiment, with the second bottle 16 housed in the second storage section 22, the axial direction of the second bottle 16 is slightly inclined vertically with respect to the length L2 direction of the blister pack 10 such that the second neck portion 1604 is positioned above the second body portion 1602. As shown in Figure 1, the second housing section 22 includes a second torso recess 22A that accommodates the lower half of the second torso 1602, which is recessed downward from the intermediate wall 30 and tilted in the direction of width W1; a second shoulder recess 22B that communicates with the second torso recess 22A and accommodates the lower half of the second shoulder 1610; and a neck recess 22C that accommodates the lower half of the second neck 1604.
[0025] As shown in Figure 2, the recess 22A for the second fuselage comprises a curved wall 2202 for the second fuselage that abuts against approximately the lower half of the second fuselage 1602 when it is lying down, a second bottom wall 2204 that abuts against the portion of the bottom 1608 of the second fuselage 1602 excluding the upper end, with its upper end connected to the intermediate wall 30, and a second lower bulge wall 2206. As the blister pack 10 is laid down with its width W1 direction tilted relative to its width W2 direction, in one width direction of the recess 22A for the second body, as shown in Figure 24, the upper end of the wall 2202 for the second body is located at the boundary between the front 1602A and the back 1602B of the second body. In the other width direction of the recess 22A for the second body, as shown in Figure 21, the upper end of the wall 2202 for the second body is located at approximately one-third of the width W1 direction of the front 1602A of the second body.
[0026] As shown in Figures 1 and 15, at the upper, opposing locations of the second body wall 2202, there are second body locking walls 2208 that can be locked from above on both sides in the width W2 direction of the blister pack 10 to the second body 1602 of the housed second bottle 16. By locking these pair of second body locking walls 2208 to the second body 1602 of the second bottle 16, the state in which the second bottle 16 is housed in the second housing section 22 is maintained. Furthermore, the upper edges of all four sides of the blister pack 10 have a rib shape that enhances strength and rigidity, as shown in Figure 9, a wide intermediate wall 30D is provided on the intermediate wall 30 where the second body locking wall 2208 is provided in one direction of the width W2 of the blister pack 10, and in one direction of the width W2 of the blister pack 10 the second body locking wall 2208 intersects with the cap tip wall 2016 and forms a corner, thus increasing the rigidity of the intermediate wall 30C where the pair of second body locking walls 2208 are provided. Therefore, the locking force of the second body locking wall 2208 to the second body 1602 is ensured, preventing the second bottle 16 from coming out of the second storage section 22 when the box 18 falls with its upper surface 1802 facing downwards.
[0027] As shown in Figure 9, with the first bottle 12 and the second bottle 16 housed in the first housing section 20 and the second housing section 22 respectively, a gap is secured between the cap 1206 of the first bottle 12 and the part of the second body section 1602 of the second bottle 16 near the bottom 1608, because the first rib 2020, which consists of the upper part of the curved wall 2018 and the upper part of the second body section wall 2202, is interposed therein. Furthermore, as shown in Figure 15, when viewed from above, the cap 1206 on the body 1602 of the second bottle 16 overlaps with the part of the body 1602 near the cap 1206 and near the bottom 1608.
[0028] As shown in Figure 2, the second lower bulge wall 2206 is provided projecting downward from the center of the second body recess 22A in the width W2 direction of the blister pack 10. The second lower bulge wall 2206 is provided so as to be able to abut against or be close to the lower surface of the rectangular box 18 used in market distribution, and so as the upper end wall 24 abuts against or is close to the upper surface of the box 18, and the first lower bulge wall 2006 and the second lower bulge wall 2206 abut against or are close to the lower surface of the box 18, thereby preventing the blister pack 10 from rattling up and down inside the box 18. As shown in Figures 2 and 10, the second bottom wall 2204 is provided so as to be able to abut against the bottom 1608 of the second body 1602 of the second bottle 16. As shown in Figures 2 and 7, the recess 22B for the second shoulder portion includes a conical wall 2210 for the second shoulder portion that is opposite to approximately the lower half of the second shoulder portion 1610 of the second bottle 16. With the second bottle 16 housed in the second storage section 22, a gap is maintained between the second shoulder wall 2210 and the second shoulder portion 1610 of the second bottle 16.
[0029] As shown in Figure 7, the neck recess 22C comprises a neck tip wall 2212 that can abut against approximately the lower half of the tip surface of the thick annular portion 1604A of the second neck portion 1604, and a neck cylindrical wall 2214 that accommodates approximately the lower half of the second neck portion 1604 and can abut against approximately the lower half of the outer circumferential surface of the thick annular portion 1604A. The tip wall 2212 for the neck portion has a bulging opening locking wall 2216 that, when the second bottle 16 is housed in the second storage portion 22, penetrates into the lower part of the opening 1604B of the second neck portion 1604 and locks into the edge of the opening 1604B. Therefore, the second neck portion 1604 is positioned such that approximately the lower half of the tip surface of the thick-walled annular portion 1604A abuts against the neck tip wall 2212, and the portion located below the thick-walled annular portion 1604A is sandwiched between the neck cylindrical wall 2214 and the opening locking wall 2216, thereby positioning the second neck portion 1604 in the height H2, width W2, and length L2 directions of the blister pack 10. In other words, the tip of the second neck portion 1604 abuts against the neck tip wall 2212, and the bottom portion 1608 of the second body portion 1602 of the second bottle 16 abuts against the second bottom wall 2204 shown in Figure 10, thereby positioning the second bottle 16 in the axial direction.
[0030] According to this embodiment, the blister pack 10 is provided with a first storage section 20 for accommodating a first bottle 12 and a second storage section 22 for accommodating a second bottle 16. When viewed from above with the first bottle 12 and the second bottle 16 housed in the first storage section 20 and the second storage section 22, respectively, as shown in Figure 15, the axial directions of the first bottle 12 and the second bottle 16 are inclined in approximately the same direction with respect to the length L2 direction of the blister pack 10. When viewed from the width W2 direction of the blister pack 10, as shown in Figure 17, the cap 1206 (first neck portion 1204) of the first bottle 12 and the portion of the second body portion 1602 of the second bottle 16 near the bottom portion 1608 overlap in the middle of the blister pack 10 in the length L2 direction. Therefore, even if the axial length L2 of the first bottle 12 is increased to increase the amount of drug that can be contained, the first bottle 12 and the second bottle 16 can be contained in the blister pack 10 while remaining separated from each other without changing the width W2, length L2, and height H2 of the blister pack 10. Therefore, it can be used without changing the size of the blister pack 10 or the shape and size of the box 18 that houses the blister pack 10, which is advantageous in keeping costs down for packaging the chemical disperser, and also advantageous in keeping costs down for transportation. Furthermore, the drug disperser, which is housed in the box 18 via the blister pack 10, is displayed in stores with the length L2 direction of the blister pack 10 facing up and down, that is, with the longitudinal direction of the box 18 facing up and down. According to this embodiment, the length L2 of the blister pack 10 can be reduced, which in turn reduces the height of the box 18, making it advantageous for displaying the product on store shelves and the like. Furthermore, as shown in Figure 17, when viewed from the width W2 direction of the blister pack 10, the first shoulder portion 1210 of the first bottle 12 and the bottom portion 1608 of the second body portion 1602 of the second bottle 16 are separated in the middle of the length L2 direction of the blister pack 10. This is advantageous for housing the first bottle 12 and the second bottle 16 in the blister pack 10 while keeping them separated from each other without changing the width W2, length L2, and height H2 of the blister pack 10. Furthermore, when the first bottle 12 is housed in the first housing section 20, the axial direction of the first bottle 12 is inclined vertically with respect to the length L2 direction of the blister pack 10 such that the first neck portion 1204 is positioned above the first body portion 1202. This is advantageous in housing the bottle 12 with the cap 1206 of the first bottle 12 and the bottom portion 1608 of the second body portion 1602 of the second bottle 16 at a greater distance from each other. This is advantageous in preventing collision between the cap 1206 of the first bottle 12 and the bottom portion 1608 of the second body portion 1602 of the second bottle 16 when subjected to impact, thereby preventing damage to the cap 1206.
[0031] Furthermore, the second body portion 1602 of the second bottle 16 has a thickness T1 and a width W1 that is greater than the thickness T1. One of the two directions in the thickness T1 direction of the second body portion 1602 of the second bottle 16 is the front surface 1602A. When the second bottle 16 is housed in the second housing portion 22, the width W1 direction of the second body portion 1602 of the second bottle 16 is inclined with respect to the width W1 direction of the blister pack 10 to such an extent that the front surface 1602A is visible from above the blister pack 10, and the front surface 1602A is facing diagonally upward. Therefore, even if the width W1 of the second body portion 1602 of the second bottle 16 is increased, the second bottle 16 can be housed without changing the size of the blister pack 10 or the box 18, which is advantageous in suppressing cost increases for the packaging of the drug disperser. Furthermore, this arrangement is advantageous in that the cap 1206 of the first bottle 12 and the bottom 1608 of the second body 1602 of the second bottle 16 are housed further apart, preventing collision between the cap 1206 of the first bottle 12 and the bottom 1608 of the second body 1602 of the second bottle 16 when subjected to impact, thereby preventing damage to the cap 1206.
[0032] Furthermore, when the second bottle 16 is housed in the second housing section 22, the axial direction of the second bottle 16 is inclined vertically with respect to the length L2 direction of the blister pack 10 such that the second neck portion 1604 is positioned above the second body portion 1602. This is advantageous in housing the bottle 16 with a greater distance between the cap 1206 of the first bottle 12 and the bottom portion 1608 of the second body portion 1602 of the second bottle 16. This prevents collision between the cap 1206 of the first bottle 12 and the bottom portion 1608 of the second body portion 1602 of the second bottle 16 when subjected to impact, thus preventing damage to the cap 1206. Furthermore, when viewed from above, the cap 1206 of the second bottle 16 near the second body 1602 overlaps with the part of the second body 1602 near the cap 1206 and near the bottom 1608. This is advantageous for enlarging the first bottle 12 and the second bottle 16 without changing the shape or size of the box 18, and is advantageous for keeping costs down regarding the packaging of the chemical disperser.
[0033] Furthermore, according to this embodiment, a blister pack 10 can be constructed with an upper wall 24, a side wall 28, and an intermediate wall 30, and the intermediate wall 30 is provided with a first storage section 20 consisting of a first body recess 20A, a first shoulder recess 20B, and a cap recess 20C, and a second storage section 22 consisting of a second body recess 22A, a second shoulder recess 22B, and a neck recess 22C. This simple configuration makes it possible to obtain a blister pack 10 storage structure that can store the first bottle 12 and the second bottle 16 separately. Furthermore, according to this embodiment, when viewed from above, a convex portion is provided on the first neck portion 1204 side of the first bottle 12, formed by the portion of the intermediate wall 30 to which the upper end of the first shoulder wall 2010, located inward in the width W2 direction of the blister pack 10 from the cap recess 20C, is connected, and the portion of the intermediate wall 30 to which the second bottom wall 2204 is connected. This convex portion is formed as a first reinforcing wall portion 2012 with increased rigidity of the intermediate wall 30, thereby preventing twisting of the blister pack 10 due to impact when the box 18 is dropped with its left side 1808 facing downwards. Therefore, the blister pack 10 twists, which is advantageous in preventing damage to the cap 1206 caused by the second body portion 1602 of the second bottle 16 near the bottom portion 1608 colliding with the cap 1206. Furthermore, according to this embodiment, the portion of the side wall 28 facing the cap 1206 where the cap recess 20C is located is formed as a second reinforcing portion 2022 with increased rigidity of the side wall 28. Therefore, when the left side 1808 of the box 18 is dropped downwards, the second reinforcing portion 2022 functions as a cushioning material and mitigates the impact, which is advantageous in preventing damage to the cap 1206 caused by the corner between the tip surface and the outer surface of the cap 1206 hitting the floor.
[0034] In this embodiment, the case in which both the first bottle 12 and the second bottle 16 are tilted has been described. However, if the second bottle 16 is small, cylindrical, etc., the axis of the second bottle 16 may be aligned along the length L2 direction of the blister pack 10, and only the first bottle 12 may be tilted.
