Description

Technical Field

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

Background Art

[0002] Containers for liquids such as liquid detergents and fabric softeners use dedicated dispensing containers, for example, plastic bottles. Many of these dispensing containers can be reused when the contents are emptied. That is, a refill pouch filled with the contents is distributed separately, the refill pouch is opened, and the contents contained in the refill pouch are refilled into a dedicated extraction container. This makes it possible to reuse the dedicated extraction container (see, for example, Patent Document 1).

[0003] By forming a female screw that can be screwed with the male screw of the pouring outlet of the dedicated extraction container and screwing the female screw onto the male screw for refilling, leakage is suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above-described configuration, since the refill pouch is turned upside down to attach the screw, the operation is difficult. In addition, it is necessary to form a female screw in the refill pouch, which takes time and effort in manufacturing. Further, since the refill pouch is formed of resin, when the refill pouch after refilling is discarded, the environmental load increases.

[0006] An object of the present invention is to provide a weighing jig and a package that can save the user's labor while suppressing the environmental load. [Means for solving the problem]

[0007] To achieve the above objective, the weighing jig according to the present invention is detachably positioned on one of a pair of inclined roof sections located at the front and rear of the upper part of the cylindrical section of a paper container, and is capable of weighing the contents contained in the paper container. The weighing jig has a bottomed cylindrical projection with a flow hole formed at the bottom and penetrating in the thickness direction, a main body that extends outward from the outer surface of the projection and is positioned to cover the inclined roof section, a cap that is detachably attached to the tip of the projection and capable of weighing the contents, a pair of holding parts that fix both the left and right ends of the main body to one of the inclined roof sections, and a guide part that guides the movement of each of the holding parts. The main body has a storage section that opens at both the left and right ends, and each of the holding parts is housed in such a way that it can be independently inserted into and removed from the opening. The pair of holding parts has an upper plate section housed in the storage section, a lower plate section that is positioned side by side with a vertical gap between it and the upper plate section, and a connecting part that connects the upper plate section and the lower plate section. The guide portion restricts the movement of the holding portion when it is housed in the housing and when it is fully extended from the housing. When the holding portion is in the housed state, the lower plate portion contacts the lower surface of one of the inclined roof portions, thereby holding the main body portion to one of the inclined roof portions.

[0008] The packaging according to the present invention comprises the above-described weighing jig and the paper container having the sloping roof portion to which the weighing jig can be attached and detached. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a weighing jig and packaging that can reduce the burden on the environment while saving the user effort. [Brief explanation of the drawing]

[0011] A package A according to one embodiment of the present invention will be described with reference to the drawings. Figure 1 is a perspective view from the front and above of an example of a package A according to the present invention. Figure 2 is a perspective view of package A with the cap portion 44 removed. In this embodiment, the directions of package A, such as "front," "back," "top," "bottom," "right," and "left," are based on package A as shown in Figure 1.

[0012] <Package A> As shown in FIG. 1, the package A according to the present invention includes a paper container 100 and a metering jig 200 attached to the paper container 100. The contents contained in the paper container 100 can include, for example, liquids such as liquid laundry detergent, fabric softener, bleach, etc., which are used by measuring. In addition to these, as the contents, liquids such as alcoholic beverages (sake, wine, shochu, etc.), beverages (coffee, milk beverages, juice, tea, etc.), seasonings (soy sauce, dressing, etc.) and sanitary products (shampoo, body soap, etc.) can also be widely adopted in the paper container 100.

[0013] <paper container 100> FIG. 3 is a perspective view seen from above the front side of the paper container 100. As shown in FIG. 3, the paper container 100 is a gable-top type container. The paper container 100 is formed by bending a single waterproofed paper (blank board) and heating a part of the inner surface of the paper container to melt and bond the inner surface films together. The paper container 100 has a cylindrical portion 10, a gable roof portion 20, and a bottom portion 30. In the paper container 100, the upper end of the cylindrical portion 10 is closed by the gable roof portion 20. Also, the lower end of the cylindrical portion 10 is closed by the bottom portion 30.

[0014] <cylindrical portion 10> The cylindrical portion 10 is a cylinder with a rectangular (here, square) horizontal cross-section. The cylindrical portion 10 has a rear panel 11, a pair of side panels 12, and a front panel 13. The front panel 13 and the rear panel 11 are arranged opposite to each other front and back. The pair of side panels 12 connect the left and right ends of the rear panel 11 and the front panel 13 respectively. The upper end portion of the cylindrical portion 10 is closed by the gable roof portion 20. Also, the lower end portion of the cylindrical portion 10 is closed by the bottom portion 30.

[0015] <gable roof portion 20> As shown in Figure 3, the gable roof section 20 has a rear-sloping roof section 21, a side top plate section 22, a front-sloping roof section 23, and a apex section 24. The rear-sloping roof section 21 is connected to the upper end of the rear panel 11 and slopes forward upwards. The front-sloping roof section 23 is connected to the upper end of the front panel 13 and slopes backwards upwards. The upper ends of the rear-sloping roof section 21 and the front-sloping roof section 23 are joined together to form the apex section 24. The apex section 24 is a flat plate that extends left and right and up and down.

[0016] The pair of side top panels 22 are positioned on both the left and right sides and are connected to the upper ends of the pair of side panels 12. The side top panels 22 are isosceles triangular in shape, with their upper ends sloping inward in the left-right direction. The side top panels 22 are positioned between the rear-sloping roof section 21 and the front-sloping roof section 23. The two side top panels 22 are positioned opposite each other in the left-right direction.

[0017] The front sloping roof section 23 has a discharge hole 231. The front sloping roof section 23 also has a spout 25. The spout 25 is cylindrical (see Figure 3), penetrates the discharge hole 231, and is fixed to the front sloping roof section 23. In other words, the spout 25 communicates the inside and outside of the paper container 100. The paper container 100 can dispense its contents to the outside through the spout 25. The spout 25 is tightly fitted to the discharge hole 231 to the extent that leakage of the contents is suppressed. Furthermore, the spout 25 has a flange (not shown), which is fixed by bonding the flange to the inner surface of the front sloping roof section 23. This suppresses leakage of the contents from the gap between the outer surface of the spout 25 and the inner surface of the discharge hole 231. The spout 25 is formed of resin, but is not limited to resin.

[0018] <Bottom 30> The bottom portion 30 is formed by folding and bonding the lower end of the cylindrical portion 10. This prevents leakage of the contents to the outside. While bonding is generally done by heating and bonding the inner film of the paper container 100, adhesive bonding or hot melt bonding may also be used. For example, when filling the paper container 100 with liquid, a bonding method that can form the bottom portion 30 tightly enough to prevent leakage of the liquid can be widely adopted.

[0019] <Weighing jig 200> Details of the weighing jig 200 will be described with reference to the drawings. Figure 4 is a front view of the weighing jig 200 with the cap portion 44 removed, with the holding portion 43 moved to the stowed position P1. Figure 5 is a front view of the weighing jig 200 with the cap portion 44 removed, with the holding portion 43 moved to the extended position P2. Figure 6 is a rear view of the weighing jig 200 with the cap portion 44 removed, with the holding portion 43 moved to the stowed position P1. Figure 7 is a rear view of the weighing jig 200 with the cap portion 44 removed, with the holding portion 43 moved to the extended position P2. Figure 8 is a side cross-sectional view of the weighing jig 200 with the cap portion 44 removed. Figure 9 is a perspective view of the cap portion 44. Figure 10 is a perspective view of the weighing jig from the bottom side. Figure 11 is an exploded perspective view of the packaging A. Figure 12 is a partially enlarged view showing the state of the main body portion 42 before attachment to the front sloping roof portion 23. Figure 13 is a magnified view of the main body 42 in contact with the forward-sloping roof section 23. Figure 14 is a magnified view of the weighing jig 200 fixed by the holding section 43.

[0020] The weighing jig 200 is made of a resin such as polypropylene, polyethylene terephthalate, or ABS resin. However, the weighing jig 200 is not limited to resin and may be made of a metal material such as aluminum or an aluminum alloy. It may also 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 constructed so as not to deform or break even if the contents adhere to it.

[0021] The weighing jig 200 has a protruding portion 41, a main body portion 42, a pair of holding portions 43, a cap portion 44, and a guide portion 50.

[0022] <Protrusion 41> The projection 41 has a bottom portion 411 and a cylindrical portion 412. The bottom portion 411 is circular when viewed from the axial direction. The cylindrical portion 412 is cylindrical and extends axially from the outer edge of the bottom portion 411. The projection 41 has a flow hole 413 formed in the bottom portion 411 that penetrates axially (see Figure 7, etc.).

[0023] The inner circumferential surface of the cylindrical portion 412 is tapered. More specifically, when the packaging body A is placed on a horizontal surface such as the floor, the inner circumferential surface is formed such that a gradient is created in which liquid flows toward the flow hole 413. With this configuration, when the packaging body A is placed on a horizontal surface, the contents inside the cylindrical portion 412 flow toward the flow hole 413 and into the inside of the paper container 100. Also, 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 inside of the paper container 100 via the flow hole 413.

[0024] This prevents the contents from accumulating in the protruding portion 41 and from spilling out when the packaging A is in use. In addition, the contents that accumulate in the cap portion 44 can be reused, eliminating waste of the contents.

[0025] The protruding portion 41 has an inlet portion 414 and a discharge portion 415. The inlet portion 414 is located on the opposite side of the cylindrical portion 412 of the bottom portion 411. The inlet portion 414 is cylindrical and surrounds the flow hole 413 of the bottom portion 411. The inlet portion 414 engages with the spout 25 located on the forward sloping roof portion 23 of the paper container 100. More specifically, the inlet portion 414 is located inside the spout 25 via a packing 60, which will be described later. This ensures that the inlet portion 414 is attached so as not to separate from the spout 25. The presence of the packing 60 between the inlet portion 414 and the spout 25 suppresses leakage when the contents flow from the spout 25 to the inlet portion 414.

[0026] As shown in Figures 6, 7, and 9, the packing 60 has a cylindrical portion 61 and a flange portion 62. The cylindrical portion 61 is cylindrical in shape. The flange portion 62 is annular in shape and extends outward from the outer surface of the axial end of the cylindrical portion 61. The bottom portion 411 has a plurality (for example, four) of ribs 416 on its rear side.

[0027] The inner circumferential surface of the cylindrical portion 61 of the packing 60 is positioned in contact with the inlet portion 414. Also, the flange portion 62 is positioned in contact with the rib 416 of the bottom portion 411. 、For example, by providing a recess in the rib 416 and allowing the flange portion 62 of the packing 60 to fit into the recess, the packing can be fixed more firmly. As a result, the packing 60 is fixed by the rib 416. This prevents the packing 60 from coming out of the inlet 414 when attaching or detaching the measuring jig 200. Also, when the inlet 414 is inserted into the spout 25, the outer surface of the cylindrical portion 61 comes into contact with the inner surface of the spout 25. Furthermore, the tip of the spout 25 comes into contact with the flange portion 62. Therefore, the effect of suppressing leakage of the contents to the outside can be enhanced.

[0028] The discharge section 415 has a nozzle that protrudes from the vicinity of the flow hole 413 in the bottom section 411. The top of the discharge section 415 is open. The discharge section 415 is in communication with the inlet section 414. As a result, the contents flow from the inlet section 414 to the discharge section 415 via the flow hole 413. The tip of the discharge section 415 is positioned outward in the axial direction from the axial tip of the cylindrical section 412.

[0029] The dispensing section 415 has a smaller cross-section than the cylindrical section 412, making it less likely for the contents to spill when pouring them into the cap section 44. In addition, the contents may flow along the outer surface of the dispensing section 415 after being poured. The dispensing section 415 is located inside the bottom 411 of the protruding section 41 and the cylindrical section 412. Therefore, the contents that flow along the outer surface of the dispensing section 415 flow downward along the tapered inner circumferential surface, pass through the flow hole 413, and return to the inside of the paper container 100. This makes it less likely for the outer surface of the measuring jig 200 to get dirty and less likely for the user's hands to get dirty. It also helps to reduce waste of the contents.

[0030] <Main body 42> As shown in Figures 2 and 11, the main body portion 42 is plate-shaped and extends outward from the outer surface of the protruding portion 41. The main body portion 42 is positioned to cover the forward sloping roof portion 23 of the gable roof portion 20 of the paper container 100. The main body portion 42 has an upper contact portion 421, a lower contact portion 422, and a storage portion 423.

[0031] As shown in Figures 5 and 6, the upper contact portion 421 is positioned on the upper part of the main body portion 42. When the main body portion 42 is positioned to cover the front sloping roof portion 23, the upper contact portion 421 contacts the front surface of the top portion 24.

[0032] The lower contact portion 422 is positioned at the bottom of the main body portion 42. The lower contact portion 422 contacts the front plate 13 when the main body portion 42 is positioned to cover the front sloping roof portion 23. In other words, the upper contact portion 421 contacts the top portion 24 and the lower contact portion 422 contacts the front plate 13, thereby positioning the main body portion 42 to cover the front sloping roof portion 23. At this time, the inlet portion 414 engages with the inside of the spout 25 via the packing 60.

[0033] As shown in Figures 2 and 4, stepped portions 424, which are thinner than the central portion, are formed at both the left and right ends of the main body portion 42. Furthermore, as shown in Figures 6, 7 and 10, a housing portion 423 is formed on the lower side of the central portion of the main body portion 42. The housing portions 423 are arranged symmetrically on the left and right sides, with the protruding portion 41 in between.

[0034] The left end of the left-side housing section 423 has an opening 425 facing the left-side stepped section 424. The upper plate section 431 of the holding section 43, described later, can be inserted through the opening 425 and housed inside the housing section 423. Similarly, the right end of the right-side housing section 423 has an opening 425 facing the right-side stepped section 424. The upper plate section 431 of the holding section 43 can be inserted through the opening 425 and housed inside the housing section 423.

[0035] The upper plate portion 431 of the holding portion 43 is slidable from side to side inside the housing portion 423. A guide portion 50 is positioned in the housing portion 423. The guide portion 50 guides the sliding of the upper plate portion 431 of the holding portion 43. Details of the guide portion 50 will be described later.

[0036] <Holding part 43> The pair of holding parts 43 are housed in the storage part 423 so that they can be inserted into and removed from the left and right openings 425. When the weighing jig 200 is attached to the paper container 100, the pair of holding parts 43 engage with the front sloping roof part 23 to hold the weighing jig 200 so that it does not fall off the paper container 100. The pair of holding parts 43 are positioned opposite each other at both ends of the main body part 42 in the left-right direction, with the protruding part 41 in between. In other words, the pair of holding parts 43 are mirror images of each other with the protruding part 41 in between. Therefore, the following explanation will refer to the holding part 43 located to the left of the protruding part 41 as a representative of the pair of holding parts 43.

[0037] As shown in Figures 4, 5, and 6, the holding portion 43 has an upper plate portion 431, a lower plate portion 432, a connecting portion 433, and a gripping portion 434. The upper plate portion 431 is rectangular in shape. The upper plate portion 431 is positioned so as to be pullable out from and insertable into the opening 425. The upper plate portion 431 is movable in a direction along a pair of parallel side surfaces 435. In other words, the holding portion 43 is reciprocally movable between a position in which the upper plate portion 431 is housed in the housing portion 423 (hereinafter sometimes referred to as the housing state P1) and a position in which the upper plate portion 431 is pulled out to its furthest extent (hereinafter sometimes referred to as the pulled-out state P2).

[0038] The movement of the upper plate portion 431 described above is carried out by being guided by the guide portion 50. Details of the configuration and operation of the guide portion 50 will be described later.

[0039] The lower plate portion 432 is positioned below the upper plate portion 431, facing it vertically. In the weighing jig 200 of this embodiment, the length of the lower plate portion 432 in the left-right direction is shorter than that of the upper plate portion 431. To further explain, when the holding portion 43 is moved to the extended state P2 (see Figures 5, 7, etc.), the lower plate portion 432 is located outside the main body portion 42.

[0040] As shown in Figures 10 to 14, the connecting portion 433 connects the left-right outer end of the upper plate portion 431 to the left-right outer end of the lower plate portion 432. The connecting portion 433 is integrally formed 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 together as a single unit.

[0041] The gripping portion 434 is plate-shaped and extends upward from the outer end of the upper plate portion 431. In other words, the gripping portion 434 is positioned on the opposite side of the upper plate portion 431 from the lower plate portion 432. The gripping portion 434 is used as a handle when moving the holding portion 43 from the retracted state P1 to the extended state P2. Also, when the gripping portion 434 is pushed inward, the holding portion 43 moves from the extended state P2 to the retracted state P1. Furthermore, the gripping portion 434 acts as a reinforcing rib, suppressing warping of the upper plate portion 431. As a result, the upper plate portion 431 is less likely to come into contact with the opening 425, and the holding portion 43 can be moved smoothly over a long period of time.

[0042] <Guide section 50> The guide portion 50 guides the smooth movement of the retaining portion 43 between the stowed state P1 and the extended state P2. The guide portion 50 has a side support portion 51, an engaging recess 52, and a bottom support portion 53.

[0043] As shown in Figures 6, 7, and 10, the side support portion 51 is positioned inside the housing portion 423. More specifically, the side support portion 51 is integrally formed with the lower surface of the main body portion 42. The side support portion 51 is positioned to be in contact with the side surface 435 of the upper plate portion 431. The side support portion 51 has a convex surface 511 that protrudes toward the side surface 435 of the upper plate portion 431. The convex surface 511 is a curved surface in plan view, and is such that the center of the holding portion 43 in the direction of movement is closest to the upper plate portion 431. The shape of the convex surface 511 in plan view may be a circular arc or an elliptical arc. In addition, it may be a geometric curve such as a cycloid or trochoid. A smooth curved shape can be widely adopted.

[0044] The engaging recess 52 is a concave surface formed on the side surface 435 of the upper plate portion 431. The engaging recess 52 has a first concave surface 521 and a second concave surface 522. The first concave surface 521 and the second concave surface 522 are arranged side by side in the direction of movement of the holding portion 43.

[0045] With respect to the opening 425, the second concave surface 522 is positioned further back than the first concave surface 521. The first concave surface 521 is a concave curved surface and appears as a curve in plan view. The first concave surface 521 has a curved shape that the convex surface 511 can contact. The convex surface 511 can contact the first concave surface 521 along its entire length. The contact between the first concave surface 521 and the convex surface 511 restricts the lateral movement of the holding portion 43. As shown in Figure 6, on the side surface 435 of the upper plate portion 431, the first concave surface 521 is formed at a position where the convex surface 511 contacts the holding portion 43 when it is in the accommodated state P1. In other words, the holding portion 43 enters the accommodated state P1 when the convex surface 511 contacts the first concave surface 521.

[0046] Here, "restricted movement" means a state in which movement does not occur even when a force smaller than a certain force is applied. In other words, the holding part 43 will not move on its own with the force applied when the weighing jig 200 is shaken or moved.

[0047] The second concave surface 522 has the same curved surface as half of the first concave surface 521. More specifically, in the direction of movement of the holding portion 43, the second concave surface 522 has the same curved surface as the outer half of the first concave surface 521. The rear end of the second concave surface 522 has a plane parallel to the direction of movement of the holding portion 43. When the convex surface 511 contacts the second concave surface 522, the holding portion 43 enters the extended state P2. The extended state P2 is achieved when the lower plate portion 432 is outside the main body portion 42, and the holding portion 43 only needs to be pulled out to at least the extended state P2. Therefore, the second concave surface 522 only needs to be able to contact the convex surface 511 and restrict the movement of the holding portion 43 toward the rear. For this reason, the second concave surface 522 has the same curved surface as half of the first concave surface 521, only on the outside in the direction of movement of the holding portion 43.

[0048] The second concave surface 522 may have the same shape as the first concave surface 521. By forming it in this way, when the convex surface 511 contacts the second concave surface 522, the holding part 43 is held in the extended state P2. For example, when the holding part 43 transports the weighing jig 200 in the extended state P2, the holding part 43 is less likely to vibrate, and abnormal noise and wear can be suppressed.

[0049] Furthermore, in the engaging recess 52 of this embodiment, the first concave surface 521 and the second concave surface 522 are arranged adjacent to each other, but this is not limited to this. For example, the first concave surface 521 and the second concave surface 522 may be formed at a certain distance apart.

[0050] Furthermore, the upper plate portion 431 has an elastic hole portion 523 that penetrates in the thickness direction near the engagement recess 52. The elastic hole portion 523 is positioned close to the first concave surface 521 and the second concave surface 522. Therefore, the engagement recess 52 is formed in a thin rod shape and is elastically deformable. When the convex surface 511 moves between the first concave surface 521 and the second concave surface 522, the boundary portion between the first concave surface 521 and the second concave surface 522 elastically deforms so that it moves into the elastic hole portion 523.

[0051] As a result, a tactile sensation (e.g., a click) is generated when the holding part 43 moves from the retracted state P1 to the extended state P2 or vice versa. Consequently, when attaching the weighing jig 200 to the front sloping roof section 23, the holding part 43 can be reliably moved to the retracted state P1, and the weighing jig 200 can be accurately and securely attached to the paper container 100.

[0052] In this embodiment, the engagement recess 52 is shown to be formed to be elastically deformable, but the embodiment is not limited to this. The side support portion 51 may also be elastically deformable. If the side support portion 51 is elastically deformable, the elastic hole portion 523 may be omitted.

[0053] The lower support portion 53 is positioned to pass through a through hole 430 formed in the center of the upper plate portion 431. The through hole 430 has at least a pair of inner surfaces 436 extending along the direction of movement of the holding portion 43. In the holding portion 43 according to this embodiment, the through hole 430 is rectangular, but is not limited to this. A configuration having a pair of inner surfaces 436 extending along the direction of movement can be widely adopted. The lower support portions 53 are arranged in pairs side by side, front to back.

[0054] The lower support portion 53 has a column portion 531 and an engaging portion 532. The column portion 531 is rectangular in shape and extends downward from the lower surface of the main body portion 42. The column portion 531 can be elastically deflected in a direction perpendicular to the direction of movement of the holding portion 43. The column portion 531 is formed integrally with the main body portion 42, but is not limited to this, and may be a separate component attached to the main body portion 42.

[0055] The engaging portion 532 extends from the tip of the column portion 531 in a direction perpendicular to the engaging portion 532. The engaging portion 532 has a contact surface 533 and an inclined surface 534. The contact surface 533 is positioned away from the tip of the column portion 531 and extends in a direction perpendicular to the column portion 531. The contact surface 533 faces the lower surface of the main body portion 42. The inclined surface 534 is inclined from the contact surface 533 toward the tip of the column portion 531 so as to approach the column portion 531.

[0056] When the holding part 43 is housed in the housing part 423, the column portion 531 of the lower support part 53 penetrates the through hole 430 of the upper plate part 431. At this time, a part of the column portion 531 is positioned in contact with the inner surface 436 of the through hole 430. The contact surface 533 also contacts the lower surface of the upper plate part 431. With the column portion 531 in contact with the inner surface 436 and the contact surface 533 in contact with the lower surface of the upper plate part 431, the holding part 43 moves. As a result, the holding part 43 moves guided by the guide part 50.

[0057] In the storage section 423, when the holding section 43 moves, the lower surface of the main body section 42 comes into contact with the upper plate section 431. In other words, the upper plate section 431 slides against the lower surface of the main body section 42. Therefore, when the holding section 43 moves to the extended state P2, the lower surface of the main body section 42 pushes against the upper surface of the upper plate section 431, thus preventing the outer side of the holding section 43 from tilting downward. In addition, the pair of column sections 531 come into contact with the opposing inner surfaces 436 of the through hole 430. This prevents the holding section 43 from tilting forward or backward when it moves between the stored state P1 and the extended state P2. In this way, the guide section 50 guides the upper plate section 431 of the holding section 43, allowing the holding section 43 to move smoothly and reliably between the stored state P1 and the extended state P2.

[0058] <Cap part 44> As shown in Figure 9, the cap portion 44 is a bottomed cylindrical shape with an opening 441 at one end in the axial direction. The cap portion 44 has an internal female thread (not shown) on its inner surface. The cap portion 44 is fixed to the protruding portion 41 by screwing the internal thread onto a male thread 417 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 dispensing portion 415. This prevents the contents contained in the paper container 100 from leaking to the outside via the measuring jig 200.

[0059] Furthermore, as shown in Figure 9, the inner circumferential surface of the cap portion 44 is provided with a scale 440. When dispensing the contents from the dispensing portion 415, the amount of contents dispensed can be measured by using the scale 440 as a guide. This makes it possible to dispense a sufficient amount of contents from the paper container 100. As a result, it is possible to use the contents without excess or deficiency. The paper container 100 and the measuring jig 200 have the configuration described above.

[0060] <Assembly of weighing jig 200> In the weighing jig 200, the holding part 43 is detachable from the main body 42. Here, the method for attaching the holding part 43 to the main body 42 and the method for removing the holding part 43 from the main body 42 will be described.

[0061] The retaining part 43 inserts the upper plate part 431 through the opening 425. At this time, it is inserted at an angle so that the rear side of the upper plate part 431 is facing downwards. Then, with the retaining part 43 inserted to a certain extent, the rear side of the upper plate part 431 is rotated upwards. As a result, the through hole 430 of the upper plate part 431 comes into contact with the inclined surface 534, and as the upper plate part 431 is moved further upwards, the inclined surface 534 is pushed by the inner surface 436. As a result, the column part 531 bends, and the engaging part 532 passes through the through hole 430. Then, the column part 531 returns to its original shape, and the contact surface 533 comes into contact with the lower surface of the upper plate part 431. In this way, the retaining part 43 is housed in the housing part 423.

[0062] Furthermore, the lower support portion 53 moves the engaging portion 532 inward relative to the inner surface 436 as the column portion 531 flexes. This separates the upper plate portion 431 from the lower support portion 53. At this time, the holding portion 43 is inclined so that its rear side is downward. In this state, the holding portion 43 can be pulled out from the opening 425 by moving it outward.

[0063] In this way, by separating the holding part 43 from the main body part 42, the part between the holding part 43 and the main body part 42 can be cleaned as needed, allowing for hygienic use.

[0064] <Attaching the weighing jig 200 to the paper container 100> Next, the procedure for attaching the weighing jig 200 to the front sloping roof portion 23 of the paper container 100 will be described with reference to the drawings. The pair of holding portions 43 of the weighing jig 200 are each set to the extended position P2 (see Figure 12). In this way, the inner ends of the lower plate portions 432 of the holding portions 43 are positioned outward in the left-right direction from the front sloping roof portion 23 of the paper container 100. In the weighing jig 200, the convex surface 511 of the side support portion 51 engages with the second concave surface 522. As a result, the holding portion 43 is stably held in the extended position P2.

[0065] As shown in Figure 13, the measuring jig 200, with its holding portion 43 in the extended position P2, is positioned to cover the front sloping roof portion 23 of the paper container 100. At this time, the inlet portion 414 is positioned inside the spout 25 via the packing 60.

[0066] As shown in Figure 14, with the weighing jig 200 positioned on the upper surface of the front sloping roof section 23, the gripping section 434 of the holding section 43 is pressed. More specifically, by pressing the gripping section 434 with a force greater than a certain amount, the convex surface 511 of the side support section 51 pushes the second concave surface 522 inward. As a result, the engaging recess 52 elastically deforms, and the convex surface 511 of the side support section 51 passes through the boundary between the first concave surface 521 and the second concave surface 522. As a result, the holding section 43 moves inward, and the portion of the upper plate section 431 that protrudes outward from the opening 425 is housed in the housing section 423. As the holding section 43 moves to the housing state P1, the lower plate section 432 moves to the underside of the front sloping roof section 23 and comes into contact with the lower surface of the front sloping roof section 23.

[0067] When the holding portion 43 is in the storable state P1, the convex surface 511 of the side support portion 51 engages with the first concave surface 521. As a result, the holding portion 43 is held by the side support portion 51. Also, when the lower plate portion 432 is positioned on the underside of the front sloping roof portion 23, it makes strong contact with the underside of the front sloping roof portion 23. As a result, the left and right sides of the main body portion 42 are firmly fixed to the front sloping roof portion 23. As a result, the weighing jig 200 is held in place by the front sloping roof portion 23 so as not to detach.

[0068] 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.

[0069] Furthermore, once the contents of the paper container 100 are used up, the user moves both the left and right holding parts 43 from the stored state P1 to the pulled-out state P2 (see Figure 13). This allows the measuring jig 200 to move upward from the front sloping roof section 23. By moving the measuring jig 200 upward, it is separated from the front sloping roof section 23 (see Figure 12). At this time, the inlet part 414 inserted into the spout 25 is pulled out to the outside. This separates the paper container 100 from the measuring jig 200. The used paper container 100 can then be replaced with a paper container 100 containing contents, and the measuring jig 200 can be attached to the paper container 100 using the same procedure as described above.

[0070] In the packaging A according to the present invention, a paper container 100 is used as the container. Therefore, compared to a configuration in which the contents are transferred from a refillable packaging to a container, the effort of transferring the contents can be reduced. In addition, since there is no refilling work, spillage or overflow of the contents during refilling can be suppressed.

[0071] Furthermore, in the packaging A according to the present invention, the paper container 100 is replaced after the contents have been used up. That is, in packaging A, the discarded paper container 100 is made of paper. Therefore, in packaging A according to the present invention, the amount of resin used and discarded can be reduced compared to when the contents are provided in a conventional resin container, and the environmental burden can be further reduced.

[0072] Furthermore, the paper container 100 in which the contents are provided is used as the container for packaging A. Therefore, the contents of the package and the contents indicated by printing on the outside of the container are always the same. This helps to prevent misuse by the user.

[0073] Furthermore, the inner diameter of the spout 25 may differ depending on the paper container 100. By replacing the packing 60 with one of a different inner diameter, a measuring jig 200 that can accommodate spouts 25 with different inner diameters can be provided. Multiple packings 60 may be distributed individually, together with the packaging A, or together with the measuring jig 200.

[0074] It should be noted that the present invention is not limited to the configuration described above, and various modifications are possible. Configurations obtained by appropriately combining the technical means disclosed for each different configuration are also included within the technical scope of the present invention. [Industrial applicability]

[0075] The packaging of the present invention can be used, for example, as a container for liquids that need to be measured before use, such as liquid detergents and fabric softeners. [Explanation of symbols]
