Description

[Technical Field]

[0001] The present invention relates to a measuring jig that is detachably attached to a paper container and a package having the measuring jig. [Background technology]

[0002] Dedicated dispensing containers, such as plastic bottles, are used to store liquids such as liquid detergents and fabric softeners. Many of these dispensing containers are designed to be reused when the contents run out. In other words, refill pouches filled with the contents are distributed separately, and the refill pouches are opened and the contents stored in the refill pouches are refilled into dedicated extraction containers. This makes it possible to reuse dedicated extraction containers (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-33067 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described configuration, the contents are poured from a pouring outlet. The contents are prone to leaking during refilling, which can stain the user's body or clothes. Therefore, in Patent Document 1, a female thread is formed that can be threaded with a male thread on the pouring outlet of the dedicated extraction container, and the female thread is threaded onto the male thread when refilling, thereby preventing leakage.

[0005] However, because the refill pouch must be turned upside down to attach the screw, it is difficult to operate. Furthermore, the refill pouch must be provided with a female screw, which requires time and effort for manufacturing. Furthermore, because the refill pouch is made of resin, disposing of the refill pouch after refilling places a heavy burden on the environment.

[0006] The present invention aims to provide a weighing tool and a package that can reduce the burden on the environment and save the user time and effort. [Means for solving the problem]

[0007] To achieve the above object, the present invention provides a weighing jig that is detachably attached to one of a pair of sloped roof sections located at the front and rear of the upper part of the tubular section of a paper container and is capable of weighing the contents contained in the paper container. The weighing jig includes a cylindrical protrusion with a through hole at its bottom, a main body section that extends outward from the outer surface of the protrusion and is positioned to cover the sloped roof section, a cap section that is detachably attached to the tip of the protrusion and can weigh the contents, and a pair of retaining sections that secure both left and right ends of the main body section to one of the sloped roof sections. The pair of retaining sections includes an upper plate section, a lower plate section that is arranged next to the upper plate section and spaced apart vertically, and a connecting section that connects the upper plate section to the lower plate section. The retaining sections hold the main body section and one of the sloped roof sections together by the upper plate section contacting the main body section and the lower plate section contacting one of the sloped roof sections.

[0008] In the measuring jig having the above configuration, the protrusion has an inlet portion that is cylindrical and surrounds the through-hole and communicates with the inside of the paper container, and a discharge portion that communicates with the inlet portion to discharge the contents and is covered by the cap portion attached to the protrusion. The inlet portion comes into contact with the inner surface of a spout that is provided on the sloped roof portion of the paper container and is used to pour the contents, and engages with the spout.

[0009] In the measuring jig having the above configuration, the inlet portion has a packing. The packing has a cylindrical portion extending in the direction of extension of the inlet portion and a flange portion expanding radially outward from one opening of the cylindrical portion. The cylindrical portion contacts the inner surface of the spout, and the flange portion contacts the tip of the spout in the protruding direction and the surface of the inlet portion facing the tip of the spout in the protruding direction.

[0010] In the measuring jig having the above configuration, the discharge portion has a nozzle extending from the bottom of the protrusion, and the inner circumferential surface of the protrusion is tapered toward a portion where the nozzle is connected to the bottom.

[0011] In the measuring jig having the above configuration, the holding portion is arranged to be slidable in the left-right direction relative to the main body portion. The holding portion has a pin that protrudes upward from the top surface of the main body portion. The upper plate portion of the holding portion has a guide hole through which the pin passes, and the guide hole is an elongated hole extending in the left-right direction. When the holding portion moves inward in the left-right direction, the lower plate portion is positioned below one of the sloping roof portions, and when the holding portion moves outward, the lower plate portion is positioned outward in the left-right direction from the left-right ends of one of the sloping roof portions.

[0012] In the measuring jig having the above-described configuration, the guide hole has a narrower width at the center in the longitudinal direction than at both end portions.

[0013] In the measuring jig having the above-described configuration, the pin has a hook portion that widens from the tip portion toward the body portion, and the guide hole has only one end portion through which the hook portion can pass.

[0014] A packaging body according to the present invention includes the above-described weighing jig and the paper container having the sloped roof portion to which the weighing jig can be attached and detached. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide a weighing tool and a package that can reduce the burden on the environment and save the user time and effort. [Brief explanation of the drawings]

[0017] A packaging body A according to one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of an example of packaging body A according to the present invention as seen from above the front side. Fig. 2 is a perspective view of packaging body A with cap portion 44 removed. In this embodiment, the directions of packaging body A, such as "front," "rear," "upper," "lower," "right," and "left," are based on packaging body A shown in Fig. 1.

[0018] <Package A> As shown in Fig. 1, a package A according to the present invention comprises a paper container 100 and a measuring jig 200 attached to the paper container 100. Examples of contents contained in the paper container 100 include liquids that are measured for use, such as liquid laundry detergent, fabric softener, and bleach. In addition to these, a wide range of liquids that can be provided in the paper container 100 can be used as contents, including alcoholic beverages (sake, wine, shochu, etc.), beverages (coffee, dairy drinks, juice, tea, etc.), seasonings (soy sauce, dressing, etc.), and hygiene products (shampoo, body soap, etc.).

[0019] <Paper container 100> FIG. 3 is a perspective view of the paper container 100 as seen from above the front. As shown in FIG. 3, the paper container 100 is a Gabel-top type container. The paper container 100 is formed by folding a single waterproofed sheet of paper (blank sheet) and heating part of the inner surface of the paper container to melt and bond the inner film together. The paper container 100 has a tubular portion 10, a gable roof portion 20, and a bottom portion 30. In the paper container 100, the upper end of the tubular portion 10 is closed by the gable roof portion 20. The lower end of the tubular portion 10 is closed by the bottom portion 30.

[0020] <Cylindrical portion 10> The cylindrical portion 10 has a cylindrical shape with a rectangular (here, square) horizontal cross section. The cylindrical portion 10 has a rear panel 11, a right side panel 12, a front panel 13, and a left side panel 14. The front panel 13 and the rear panel 11 are arranged facing each other in the front-to-rear direction. The right side panel 12 connects the right ends of the rear panel 11 and the front panel 13. The left side panel 14 connects the left ends of the rear panel 11 and the front panel 13. The upper end of the cylindrical portion 10 is closed by a gable roof portion 20. The lower end of the cylindrical portion 10 is closed by a bottom portion 30.

[0021] <Gable roof section 20> As shown in Figure 3, the gable roof section 20 has a rear-sloping roof section 21, a right-side top panel section 22, a front-sloping roof section 23, a left-side top panel section 24, and an apex 25. The rear-sloping roof section 21 is connected to the upper end of the rear panel 11 and slopes forward at its top. The front-sloping roof section 23 is connected to the upper end of the front panel 13 and slopes backward at its top. The upper ends of the rear-sloping roof section 21 and the front-sloping roof section 23 are glued together to form the apex 25. The apex 25 is a flat plate that extends left and right and up and down.

[0022] The right side top panel portion 22 is connected to the upper end of the right side panel 12. The right side top panel portion 22 is shaped like an isosceles triangle, with the upper portion sloping inward in the left-right direction. The right side top panel portion 22 is disposed between the rear sloping roof portion 21 and the front sloping roof portion 23.

[0023] The left side top panel portion 24 is connected to the upper end of the left side panel 14. The left side top panel portion 24 is shaped like an isosceles triangle, with the upper portion sloping inward in the left-right direction. The left side top panel portion 24 is disposed between the rear sloping roof portion 21 and the front sloping roof portion 23. The right side top panel portion 22 and the left side top panel portion 24 are disposed opposite each other in the left-right direction.

[0024] The front sloped roof portion 23 has a through hole 231. The front sloped roof portion 23 also has a spout 26. The spout 26 is cylindrical (see FIG. 3), passes through the through hole 231, and is fixed to the front sloped roof portion 23. In other words, the spout 26 connects the inside and outside of the paper container 100. The contents of the paper container 100 can be poured to the outside through the spout 26. The spout 26 is in close contact with the through hole 231 to an extent that leakage of the contents is suppressed. The spout 26 also has a flange portion (not shown), which is fixed by bonding to the inner surface of the front sloped roof portion 23. This prevents leakage of the contents from the gap between the outer surface of the spout 26 and the inner surface of the through hole 231. The spout 26 is made of, but is not limited to, resin.

[0025] <Bottom 30> The bottom 30 is formed by folding and gluing the lower end of the cylindrical tubular portion 10. This prevents leakage of the contents to the outside. The adhesion may be performed using an adhesive or a hot melt. For example, when filling the paper container 100 with liquid, a wide variety of adhesion methods can be used that can form the bottom 30 tightly enough to prevent liquid leakage.

[0026] <Measuring Jig 200> The details of the measuring jig 200 will be described with reference to the drawings. FIG. 4 is a front view of the measuring jig 200 with the holding portion 43 moved to the holding position P1 and the cap portion 44 removed. FIG. 5 is a front view of the measuring jig 200 with the holding portion 43 moved to the open position P2 and the cap portion 44 removed. FIG. 6 is a rear view of the measuring jig 200. FIG. 7 is a side cross-sectional view of the measuring jig 200 with the cap portion 44 removed. FIG. 8 is a perspective view of the cap portion 44. FIG. 9 is an exploded perspective view of the package A. FIG. 10 is a partial enlarged view of the main body portion 42 immediately before the holding portion 43 is attached. FIG. 11 is a partial enlarged view of the main body portion 42 with the holding portion 43 attached. FIG. 12 is a partial enlarged view of the measuring jig 200 attached to the front sloped roof portion 23. FIG. 13 is a partial enlarged view of the measuring jig 200 fixed by the holding portion 43.

[0027] The measuring jig 200 is formed of a resin such as polypropylene, polyethylene terephthalate, ABS resin, etc. Note that the measuring jig 200 is not limited to resin, and may be formed of a metal material such as aluminum or an aluminum alloy. Furthermore, the measuring jig 200 may be made of paper as long as it has the rigidity to prevent it from falling off when attached to the paper container 100 and is not deformed or damaged even when the contents are attached to it.

[0028] The measuring jig 200 has a protruding portion 41, a main body portion 42, a pair of holding portions 43, a cap portion 44, an upper hook portion 451, and a lower hook portion 452. The protruding portion 41 has a bottom portion 411 and a tubular portion 412. The bottom portion 411 has a circular shape when viewed in the axial direction. The tubular portion 412 has a cylindrical shape extending in the axial direction from the outer edge of the bottom portion 411. A through-hole 413 is provided in the bottom portion 411 (see FIG. 7, etc.).

[0029] The inner circumferential surface 410 of the tubular portion 412 is tapered. More specifically, when the packaging body A is placed on a horizontal surface such as a floor, the inner circumferential surface 410 is formed so as to form a gradient that causes liquid to flow toward the through-hole 413. With this configuration, when the packaging body A is placed on a horizontal surface, the contents inside the tubular portion 412 flow toward the through-hole 413 and into the paper container 100. Furthermore, when the cap portion 44 is attached to the protruding portion 41, the contents accumulated in the cap portion 44 flow into the protruding portion 41 and into the paper container 100 via the through-hole 413.

[0030] This prevents the contents from accumulating in the protruding portion 41 and from dripping to the outside when the package A is in use. Also, the contents accumulated in the cap portion 44 can be reused, eliminating waste of the contents.

[0031] The protruding portion 41 has an inlet portion 414 and an outlet portion 415. The inlet portion 414 is located on the opposite side of the bottom portion 411 from the tubular portion 412. The inlet portion 414 is tubular and surrounds the through-hole 413 in the bottom portion 411. The inlet portion 414 engages with the spout 26 located on the front sloped roof portion 23 of the paper container 100. More specifically, the inlet portion 414 is located inside the spout 26 via a gasket 5, which will be described later. This allows the inlet portion 414 to be attached so that it does not separate from the spout 26. The presence of the gasket 5 between the inlet portion 414 and the spout 26 prevents leakage when the contents flow from the spout 26 to the inlet portion 414.

[0032] 6, 7, and 9, the packing 5 has a tubular portion 51 and a flange portion 52. The tubular portion 51 is cylindrical. The flange portion 52 is annular and extends outward from the outer surface of the axial end of the tubular portion 51. The back surface of the bottom portion 411 has a plurality of (for example, four) ribs 416.

[0033] The inner peripheral surface of the tubular portion 51 of the packing 5 is placed in contact with the inlet portion 414. Furthermore, the flange portion 52 is placed in contact with the rib 416 of the bottom portion 411, and is more firmly fixed by, for example, providing a recess in the rib 416 and fitting the flange portion 52 of the packing 52 into the recess. As a result, the packing 5 is fixed by the rib 416. This prevents the packing 5 from coming off the inlet portion 414 when the measuring jig 200 is attached or detached. Furthermore, when the inlet portion 414 is inserted into the spout 26, the outer surface of the tubular portion 51 comes into contact with the inner surface of the spout 26. Furthermore, the tip of the spout 26 comes into contact with the flange portion 52. This enhances the effect of preventing the contents from leaking to the outside.

[0034] Discharge portion 415 has a nozzle protruding from near through-hole 413 of bottom portion 411. Discharge portion 415 is open at the top. Discharge portion 415 communicates with inlet portion 414. This allows the contents to flow from inlet portion 414 through through-hole 413 into discharge portion 415. The tip of discharge portion 415 is positioned outward in the axial direction from the axial tip of tubular portion 412.

[0035] The discharge part 415 has a smaller cross section than the tubular part 412, so that the contents are less likely to spill when poured into the cap part 44. In addition, after the contents are poured, they may flow along the outer surface of the discharge part 415. The discharge part 415 is disposed inside the bottom part 411 of the protrusion 41 and the tubular part 412. Therefore, the contents that flow along the outer surface of the discharge part 415 flow downward along the tapered inner circumferential surface 410, pass through the through-hole 413, and return to the inside of the paper container 100. This prevents the outer surface of the measuring jig 200 from getting dirty, and prevents the user's hands from getting dirty. In addition, waste of the contents can be reduced.

[0036] As shown in FIGS. 5 and 6 , the upper hook portion 451 is disposed on the upper portion of the weighing jig 200. More specifically, the upper hook portion 451 is disposed on the outer surface of the protruding portion 41. The upper hook portion 451 engages with the apex portion 25 when the weighing jig 200 is attached to the front sloping roof portion 23. The lower hook portion 452 is disposed on the lower portion of the weighing jig 200. More specifically, the lower hook portion 452 is disposed on the lower portion of the main body portion 42. The lower hook portion 452 contacts the front panel 13 when the weighing jig 200 is attached to the front sloping roof portion 23. The engagement of the upper hook portion 451 with the apex portion 25 and the contact of the lower hook portion 452 with the front panel 13 ensures that the weighing jig 200 is stably attached to the front sloping roof portion 23. At this time, the inlet portion 414 engages with the inside of the spout 26 via the gasket 5.

[0037] The pair of holding parts 43 hold the measuring jig 200 so that it does not fall off the paper container 100 when the measuring jig 200 is attached to the paper container 100. The pair of holding parts 43 are arranged at both left and right ends of the main body 42, facing each other with the protrusion 41 in between. In other words, the pair of holding parts 43 are in a mirror image relationship with the protrusion 41 in between. Therefore, the following description will be given with reference to the holding part 43 arranged on the left side of the protrusion 41 as a representative of the pair of holding parts 43.

[0038] As shown in Figures 4, 5, 6, etc., the holding portion 43 has an upper plate portion 431, a lower plate portion 432, a connecting portion 433, and a pin 434. The upper plate portion 431 is disposed above the main body portion 42. The inner side of the upper plate portion 431 in the left-right direction has a concave curved shape. More specifically, the inner side in the left-right direction has a shape that fits along the protrusion 41. At that time, when the holding portion 43 moves to the innermost position in the left-right direction (hereinafter referred to as holding position P1) (see Figures 4 and 13), the holding portion 43 does not interfere with the protrusion 41.

[0039] The lower plate portion 432 is disposed below the upper plate portion 431 and vertically opposed to the upper plate portion 431. The length in the left-right direction of the lower plate portion 432 is shorter than that of the upper plate portion 431. To explain further, when the holding portion 43 moves to the outermost position in the left-right direction (hereinafter referred to as the open position P2) (see FIG. 12), the lower plate portion 432 is positioned outer than the front sloping roof portion 23 and the main body portion 42.

[0040] 10 to 13, etc., the connecting portion 433 connects the outer left-right end of the upper plate portion 431 to the outer left-right end of the lower plate portion 432. The connecting portion 433 is formed integrally with the upper plate portion 431 and the lower plate portion 432. This allows the upper plate portion 431 and the lower plate portion 432 to move integrally.

[0041] The pins 434 protrude upward from the upper surface of the main body 42. The pins 434 are arranged side by side in the front and rear of the main body 42. As shown in FIG. 10, each pin 434 is formed by dividing it into two parts, one for the front and one for the rear. The pins 434 have a pillar portion 4341 and a hook portion 4342. The pillar portion 4341 protrudes upward from the main body 42 and is arranged side by side in the front and rear. The two pillar portions 4341 are configured to have a slit in the center in the front-to-rear direction.

[0042] The hook portion 4342 has a portion that extends outward beyond the pillar portion 4341, and has an inclination that extends upward and toward the center. The pair of pillar portions 4341 of the pin 434 are formed so that they can elastically deform in directions toward and away from each other. When the pillar portions 4341 elastically deform, the outermost portions of the hook portion 4342 move inward. This allows the hook portion 4342 to pass through a hole that is smaller than the shape of its outermost portion.

[0043] The pin 434 passes through a guide hole 435 formed in the upper plate portion 431. The guide hole 435 is an elongated hole that extends in the direction in which the holding portion 43 moves, in this case, the left-right direction. The guide hole 435 has a first hole portion 436, a second hole portion 437, and a third hole portion 438.

[0044] The first hole 436, the second hole 437, and the third hole 438 are in communication with each other and are arranged side by side from the inside to the outside when the holder 43 is attached to the main body. The first hole 436 is rectangular in plan view (see FIGS. 4, 5, and 10 to 13). The first hole 436 has a rectangular shape that allows the column 4341 to be inscribed therein, and has a smaller outer diameter in the axial direction than the largest part of the hook 4342, which is the part farthest from the tip. This configuration prevents the pin 434 from slipping out of the guide hole 435.

[0045] In this embodiment, since the shape of the hook portion 4342 is rectangular when viewed from the axial direction, the first hole portion 436 is also rectangular to match that shape, but is not limited to this. As will be described in detail later, the post portion 4341 elastically deforms to allow the hook portion 4342 to pass through, and a wide variety of shapes and sizes can be adopted so that the hook portion 4342 can be caught after passing through.

[0046] The third hole 438 has a circular shape. The third hole 438 has a shape inscribed with the column portion 4341. In other words, the diameter of the third hole 438 is smaller than the outer diameter in the axial direction of the largest portion of the hook portion 4342, which is the portion farthest from the tip. This configuration prevents the pin 434 from slipping out of the guide hole 435.

[0047] The second hole portion 437 connects the first hole portion 436 and the third hole portion 438. The width of the second hole portion 437 in the direction perpendicular to the longitudinal direction of the guide hole 435 is narrower than the first hole portion 436 and the third hole portion 438.

[0048] The two guide holes 435 are arranged in parallel. Furthermore, the guide holes 435 have the same shape, and the first hole portions 436, the second hole portions 437, and the third hole portions 438 are aligned in the left-right direction. By configuring the two guide holes 435 in this way, the holding portion 43 can slide in the left-right direction with the two pins 434 passing through the guide holes 435, respectively.

[0049] FIG. 8 is a perspective view of the cap portion 44 as seen from the opening 441 side. As shown in FIG. 8, the cap portion 44 is a cylindrical bottomed portion having the opening 441 at one axial end. The cap portion 44 has a female thread (not shown) on its inner surface. The cap portion 44 is fixed to the protruding portion 41 by screwing the female thread into a male thread 417 (see FIGS. 5, 7, etc.) provided on the outer circumferential surface of the cylindrical portion 412 of the protruding portion 41. In this way, the cap portion 44 covers the protruding portion 41 and the discharge portion 415. This makes it possible to prevent the contents contained in the paper container 100 from leaking to the outside via the measuring jig 200.

[0050] 8, a scale 440 is provided on the inner peripheral surface of the cap portion 44. When discharging the contents from the discharge portion 415, the amount of the contents to be discharged can be measured using the scale 440 as a guide. This makes it possible to discharge a necessary and sufficient amount of the contents from the paper container 100. As a result, the contents can be used without excess or shortage.

[0051] 10, in the measuring jig 200, the main body 42 and the holding part 43 are separable. The following describes how to attach the holding part 43 to the main body 42. The holding part 43 is placed above the main body 42. At this time, the holding part 43 is placed so that the pin 434 and the first hole part 436 of the guide hole 435 overlap one another vertically.

[0052] In this state, the holding portion 43 is moved toward the main body portion 42. As a result, the peripheral portion of the first hole portion 436 comes into contact with the hook portion 4342 of the pin 434. Then, as the holding portion 43 moves, the inner periphery of the first hole portion 436 presses the inclined surface of the hook portion 4342, causing the pillar portion 4341 to elastically deform inward. By further moving the holding portion 43 toward the main body portion 42, the holding portion 43 penetrates the first hole portion 436. As a result, the force acting on the hook portion 4342 from the first hole portion 436 is released, and the pillar portion 4341 returns to its original shape.

[0053] This causes the hook portion 4342 to engage with the peripheral portion of the first hole portion 436 of the holding portion 43. As a result, the holding portion 43 is prevented from falling off from the main body portion 42. When the pin 434 penetrates the first hole portion 436, the curved surface portion of the pillar portion 4341 is inscribed in the first hole portion 436. Furthermore, the inner circumferential surface of the third hole portion 438 has approximately the same inner diameter as the pillar portion 4341. Therefore, when the pillar portion 4341 is in the third hole portion 438, the pin 434 does not come out.

[0054] The width of the guide hole 435 in the second hole portion 437 in the short direction is narrower than that of the first hole portion 436 and the third hole portion 438. Therefore, when the pin 434 is in the first hole portion 436 or the third hole portion 438, the pillar portion 4341 bends and moves to the second hole portion 437 only when a force acting to move the holding portion 43 in the left-right direction is applied. In other words, when the pin 434 is in the first hole portion 436 or the third hole portion 438, the movement of the holding portion 43 is restricted. When the pillar portion 4341 is in the first hole portion 436, the holding portion 43 is in the open position P2. When the pillar portion 4341 is in the third hole portion 438, the holding portion 43 is in the holding position P1.

[0055] With the pin 434 passing through the first hole 436, the holder 43 is in the open position P2. As shown in FIG. 11, when the holder 43 is in the open position P2, the lower plate 432 of the holder 43 is positioned outward from the main body 42. Then, with the holder 43 in the open position P2, the measuring jig 200b is positioned so as to cover the front sloping roof 23 of the paper container 100. At this time, the lower plate 432 is positioned below and outward from the front sloping roof 23 in a plan view, that is, the holder 43 is in the open position P2 (see FIG. 12). At this time, the inlet 414 is positioned inside the spout 26 via the gasket 5.

[0056] With the measuring jig 200 placed on the upper surface of the front sloping roof portion 23, the holding portion 43 is moved inward in the left-right direction toward the protruding portion 41. At this time, the outer peripheral surfaces of the pair of pillars 4341 are pressed by the second hole portions 437. The pair of pillars 4341 then bend toward each other. As a result, the pair of pillars 4341 have a width that allows them to pass through the second hole portions 437.

[0057] By further moving the holding portion 43, the lower plate portion 432 moves to the holding position P1 where it comes into contact with the lower surface of the front sloped roof portion 23 (see FIG. 13). At this time, when the pair of pillars 4341 pass through the second hole portion 437 and reach the third hole portion 438, the pair of pillars 4341 return to their original shape. This limits the movement of the holding portion 43 from the holding position P1 to the open position P2.

[0058] When the holding part 43 is in holding position P1, the upper plate part 431 contacts the upper surface of the main body part 42, and the lower plate part contacts the underside of the front sloping roof part 23. The weighing jig 200 has holding parts 43 on both the left and right sides. By moving both of the left and right holding parts 43 to holding position P1, the left and right sides of the main body part 42 are firmly fixed to the front sloping roof part 23. This holds the weighing jig 200 so that it does not come off the front sloping roof part 23.

[0059] In this embodiment, for ease of understanding, the first hole portion 436 and the hook portion 4342 are rectangular in shape as viewed in the axial direction, but this is not limiting. The first hole portion and the hook portion can have any shape as viewed in the axial direction that allows the hook portion to pass through the first hole portion and prevents the hook portion from slipping out after passing through. The post portion 4341 also has a split pin shape with a slit in the center, but this is not limiting. As described above, any configuration can be used that allows the pin 434 to pass through the guide hole 435 and allows the hook portion 4342 to engage with the peripheral portion of the guide hole 435.

[0060] Furthermore, when the contents contained in the paper container 100 have been used up, the user moves both the left and right holding parts 43 from the holding position P1 to the open position P2 (see FIG. 12). This allows the measuring jig 200 to move upward from the front sloping roof part 23. Then, by moving the measuring jig 200 upward, the measuring jig 200 is separated from the front sloping roof part 23 (see FIG. 11). At this time, the inlet part 414 inserted into the spout 26 is pulled out to the outside. This separates the paper container 100 and the measuring jig 200. Then, the paper container 100 with the contents used up can be replaced with a paper container 100 containing the contents, and the measuring jig 200 can be attached to the paper container 100 using the same procedure as described above.

[0061] In the package A according to the present invention, the paper container 100 that provides the contents is used as the container, so it is possible to further reduce the amount of synthetic resin used and the amount of waste, thereby reducing the environmental burden.

[0062] Furthermore, in the packaging A according to the present invention, after the contents are used up, the contents are replenished by replacing the paper container 100. In other words, when the contents are replenished, the paper container 100 that is discarded is made of paper. On the other hand, when transferring contents from a storage bag made of resin film to a conventional container made of resin, the storage bag made of resin film is discarded. Therefore, by using the packaging A according to the present invention, the amount of resin waste can be reduced, and the environmental burden can be further suppressed.

[0063] Furthermore, because the paper container 100 containing the contents is used as the container for the package A, the contents of the contents and the contents displayed by printing on the outside of the container can always be the same, which makes it possible to prevent misuse by users.

[0064] Furthermore, the inner diameter of the spout 26 may differ depending on the paper container 100. By replacing the gasket 5 with a different inner diameter, it is possible to provide a measuring jig 200 that can accommodate spouts 26 with different inner diameters. Multiple gaskets 5 may be distributed by themselves, together with the package A, or together with the measuring jig 200.

[0065] Furthermore, when the holding portion 43 is in the open position P2, the hook portion 4342 of the pin 434 is pinched with fingers or the like to deform the post portions 4341 so that they approach each other. This allows the hook portion 4342 to pass through the first hole portion 436. As a result, the holding portion 43 can be separated from the main body portion 42. By separating the holding portion 43 from the main body portion 42 in this manner, the area between the holding portion 43 and the main body portion 42 can be cleaned, allowing for use in a hygienic state. Furthermore, by tilting the inner ends of the lower plate portion 432 in the left-right direction so that they approach the upper plate portion 431, the holding force of the holding portion 43 can be increased.

[0066] In the measuring jig 200 of this embodiment, the holding portion 43 is supported by the pin 434 to prevent it from falling off, but this is not limited to this. A configuration in which the holding portion 43, which is provided separately, is attached after the main body portion 42 is placed on the front sloped roof portion 23, may also be adopted. In other words, the measuring jig 200 may be configured such that the protrusion 41 and the main body portion 42, and the holding portion 43 are separated from each other. Furthermore, in this embodiment, the pin 434 is configured to be able to pass through the first hole portion 436, but may also be able to pass through the third hole portion 438.

[0067] <Modification> Fig. 14 is a partially enlarged view of packaging body B before a modified measuring jig 200b is attached to the paper container 100. Fig. 15 is a partially enlarged view of packaging body B in a state where a modified measuring jig 200b is attached to the paper container 100. In packaging body B shown in Figs. 14 and 15, a holding portion 46 of the measuring jig 200b is different from the holding portion 43 of the measuring jig 200 of packaging body A. In other respects, packaging body B has the same configuration as packaging body A. Therefore, parts of packaging body B that are substantially the same as those of packaging body A are given the same reference numerals, and detailed descriptions of the same parts will be omitted.

[0068] 14 and 15, in a modified measuring jig 200b, recesses 421 are formed on both the left and right ends of a main body 42b, and a holding portion 46 is disposed in the recesses 421. The holding portion 46 may be integral with the main body 42b or may be attached to the main body 42b.

[0069] In the measuring jig 200b of this modified example, the holding portion 46 is formed integrally with the main body portion 42b. The holding portion 46 has an upper plate portion 461, a lower plate portion 462, and a connecting portion 463. The inner shape of the upper plate portion 461 in the left-right direction is linear, and the upper plate portion 461 is connected integrally with the main body portion 42b. In other respects, it differs from the upper plate portion 431 of the holding portion 43. Furthermore, the lower plate portion 462 and the connecting portion 463 have the same configuration as the lower plate portion 432 and the connecting portion 433 of the holding portion 43. Therefore, detailed description thereof will be omitted.

[0070] The left-right inner side of the upper plate portion 431 is a hinge portion 460 that connects to the main body portion 42 and allows the holding portion 46 to rotate up and down. The hinge portion 460 is formed thinner than other portions so that the holding portion 46 can move. However, this is not limited to this, and the hinge portion may have a shape that allows rotation using an axis. The hinge portion may also be configured with a plurality of slits formed by through-holes.

[0071] Typically, the holding portion 46 is positioned so that the upper plate portion 461 is flush with the main body portion 42 (see FIG. 15). Then, the holding portion 46 is pulled upward (see FIG. 14). At this time, the hinge portion 460 may deform, or the upper plate portion 461 may be bent and deformed. In this state, the measuring jig 200b is attached to the upper surface of the front inclined roof portion 23. Then, by returning the holding portion 46 to its original shape, the lower plate portion 462 moves to the lower surface of the front inclined roof portion 23. As a result, the upper plate portion 461 comes into contact with the upper surface of the front inclined roof portion 23, and the lower plate portion 462 comes into contact with the lower surface of the front inclined roof portion 23, respectively. As a result, the holding portion 46 holds the front inclined roof portion 23, and the measuring jig 200b is attached to the front inclined roof portion 23.

[0072] Note that attachment and detachment can be facilitated by forming the lower plate portion 462 and the connecting portion 463 to be elastically deformable. Furthermore, by inclining the inner end portions in the left-right direction of the lower plate portion 462 so that they approach the upper plate portion 461, the holding force of the holding portion 46 can be increased.

[0073] The present invention is not limited to the above-described configuration, and various modifications are possible. Configurations obtained by appropriately combining the technical means disclosed in different configurations are also included in the technical scope of the present invention.
