However, the configurations, numerical values, etc. described in the following embodiments are merely examples, and modifications and changes are free, and the technical scope of the present invention is not limited to the following descriptions.

An outer container as a preferred embodiment of the present invention will be described with reference to FIGS. 1A to 7. FIG. First, with reference to FIG. 1A, the usage method of the packaging box 1 using the exterior container which concerns on this embodiment is demonstrated. The packaging box 1 includes an outer container 10 and an inner container 20 housed inside the outer container 10 . The user 100 holds and lifts the left and right side portions of the outer container 10 (the packaging box 1) in which the inner container 20 is accommodated, and tilts the packaging box 1 in a predetermined direction to fill the inner container 20. Pour out the contents. Here, the packaging box 1 is also called a pouch-in box or the like because the packaging box 1 contains an inner container 20 such as a pouch inside the outer container 10 .

By using such a packaging box 1, the user 100 can pour out the contents from the packaging box 1 into the refillable bottle 110, as shown in FIG. 1A(a), for example. Also, the user 100 can pour the contents from the packaging box 1 into the measuring cap 120 as shown in FIG. 1A(b). Furthermore, as shown in FIG. 1A(c), the user 100 can pour out the content liquid from the packaging box 1 into the detergent tank of the washing machine 130 having an automatic detergent injection function. As described above, when the packaging box 1 is used, the contents filled in the inner container 20 can be transferred to a smaller container than the inner container 20, and the inner container 20 can be used as it is without subdividing. and the usability is improved. The external container 10 is a container made of paper, for example, a container made of cardboard or cardboard.

Next, with reference to FIGS. 1B(a) to 1B(f), a procedure for assembling the exterior container 10 (packaging box 1) and making it ready for use will be described. These figures are perspective views of the exterior container 10 (packaging box 1) as viewed obliquely from the upper right. As shown in FIG. 1B(a), the exterior container 10 (packaging box 1) is a rectangular parallelepiped box in the initial state. As shown in the schematic cross-sectional view of FIG. 1B(a1), before the packaging box 1 is used, the inner container 20 and the attachment 30 are housed inside the outer container 10 . That is, the packaging box 1 is sold in a state in which the inner container 20 is housed inside the outer container 10 . In addition, the outer container 10 and the inner container 20 may be sold separately. There is a need to.

Next, as shown in FIG. 1B(b), the user 100 opens the top surface portion 12 of the outer container 10, takes out the attachment 30 accommodated inside the outer container 10, and further removes the cut piece. 18 is separated (see FIG. 1B(a1)).

Then, as shown in FIGS. 1B(c) and (d), the user 100 attaches the removed attachment 30 to a predetermined position on the upper side of the front portion 11 of the exterior container 10 . Then, the user 100 bends the portion of the front portion 11 to which the attachment 30 is attached toward the top surface portion 12, and the corner portion between the front portion 11 and the top surface portion 12 is chamfered. A portion 11a is formed.

After forming the inclined portion 11a, as shown in FIGS. 21 is pulled out and inserted. Finally, the user 100 hooks the pulled-out pouring spout part 21 to the attachment 30 so as to engage and lock it.

Next, as shown in FIG. 1B(e), the user 100 forms a grip portion 19 for gripping the packaging box 1. As shown in FIG. The grip portion 19 is formed near the center of the outer container 10 in the height direction. The grip portion 19 is used when the user 100 lifts the packaging box 1 to pour out the contents filled in the inner container 20 or carries and moves the packaging box 1 .

The grip part 19 is formed by the user 100 bending part of the pair of side parts (13, 14) and part of the back part (15, 16) of the outer container 10 toward the inside of the outer container 10 to form a concave shape. It is formed by In addition, as shown in the top view of FIG. 1B(f), the packaging box 1 (outer container 10) after the formation of the grip portion 19 is close to the rear portions (15, 16) of the side portions (13, 14). It becomes the part which became dented toward the inside of the outer container 10 among the parts.

Thus, since the gripping width of the gripping portion 19 is narrower than the lateral width of the outer container 10, the shape is such that the user 100 can easily grip it even if the grip strength is weak. The packaging box 1 can be possessed and used. Further, even when the grip portion 19 is formed, the inner container 20 housed inside the outer container 10 is sandwiched by part of the side portions (13, 14) that are bent inward. , does not contract.

Next, with reference to FIGS. 1C(a) to 1C(c), handling of the cap 21d attached to the dispensing spout portion 21 will be described.

The user 100 unscrews the cap 21d attached to the ejection portion 21a of the ejection spout portion 21 and removes the cap 21d (FIG. 1C(a)). Next, the user 100 selects a storage portion having a size corresponding to the size (diameter) of the cap 21d from the storage portions 12a, 12b, and 12c provided on the top surface portion 12 of the outer container 10 (FIG. 1C). (b)), the selected storage portion 12a is stored by fitting the cap 21d (FIG. 1C(c)). By providing the storage portions 12a, 12b, and 12c in this way, it is possible to prevent the cap from being lost.

In this state, the user 100 grips the grip portion 19 to lift the outer container 10 (packaging box 1) and pour out the contents from the pour portion 21a. When the pouring is finished, the user 100 removes the cap 21d stored in the storage part 12a from the storage part 12a, and attaches it by screwing it onto the spout part 21 in order to close the pouring part 21a again. The sizes (diameters) of the three storage portions 12a, 12b, and 12c are preferably different from each other as illustrated. Thus, if the sizes of the three storage portions 12a, 12b, and 12c are different from each other, it is possible to accommodate caps 21d of various shapes and sizes.

Here, the inner container 20 housed in the outer container 10 will be described with reference to FIG. 1D. The inner container 20 (pouch) is a bag-like container having a pair of front and rear front portions made of a sheet material. For example, a pouch is made by using a laminated film made of plastic as a sheet material, and cutting one or more sheet materials (film materials) into a predetermined shape that has been designed in advance. By performing cutting processing, it is formed as a bag-like container for containing the contents.

The inner container 20 (pouch) shown in FIG. 1D is, for example, a standing pouch, and is a self-supporting container. The inner container 20 is provided with an accommodating portion for accommodating contents between two sheet materials (front side sheet and back side sheet) that are superimposed, and each seal portion is formed at the edge of the front side sheet and the back side sheet. It has The seal portion has two opposed side seal portions 20a and 20b, and a top seal portion 20c that seal the front side sheet and the back side sheet. The seal portion further includes a bottom seal portion 20d that seals the gusseted portion 20e at the bottom of the front side sheet and the back side sheet.

In the inner container 20, the corner portion between one side seal portion 20a and the top seal portion 20c of the two side seal portions 20a and 20b is obliquely cut off to form the side seal portion 20a and the top seal portion 20c. An inclined seal portion 20f is formed to connect between the and. In the present embodiment, the inclined seal portion 20f is inclined at about 45° with respect to the side seal portion 20a (or the top surface seal portion 20c). 50° is more preferred.

A pouring spout part 21 for pouring out the contents contained in the inner container 20 is attached to the inclined seal part 20f. The extraction spout portion 21 is attached so as to be substantially orthogonal to the outer edge of the inclined seal portion 20f. One end of the spout portion 21 is arranged to be positioned outside the inner container 20, and the other end is arranged to be positioned at the inner edge of the inclined seal portion 20f.

Note that the cap 21d is, for example, a screw cap, and FIG. 1D shows a state where the cap 21d is screwed onto the dispensing spout portion 21 before opening. When the screwing of the cap 21d is released and the cap 21d is removed from the spout portion 21, the content liquid can be poured out.

Further, the inner container 20 (pouch) made of a sheet material can be used by accommodating a wide range of contents such as liquids, powders, granules, and other solids. In addition, in a pouch, for example, the cap or the like is removed from a state in which the contents are enclosed, the pouring part or the outlet is opened, the contents are poured out or taken out, and then the pouring part or the outlet is sealed again. The container is then closed and sealed so that the contents can be stored and repeatedly poured out and taken out.

In this embodiment, since the inner container 20 is housed in the outer container 10 and used, even if the remaining amount of the inner container 20 is low, the inner container 20 can stand on its own and can be easily poured out.

Next, the exterior container 10 will be described with reference to FIGS. 2A and 2B. 2A shows a state in which the outer container 10 is used as a transport box, that is, a box for moving the inner container 20 while the inner container 20 is accommodated in the outer container 10. FIG. 10 usage states, that is, the states in which the contents of the inner container 20 are poured out. It should be noted that illustration of the attachment 30 is omitted in FIG. 2B. Also, the capacities of the inner container 20 accommodated in the outer container 10 are, for example, approximately 1.8 [l], 1.4 [l], and 1.2 [l]. These can be changed according to the capacity of the inner container 20 . Furthermore, in this embodiment, the height×width×depth of the outer container 10 is approximately 309.0 mm×91.0 mm×209.0 mm.

The exterior container 10 is a box-shaped (rectangular parallelepiped) container. The exterior container 10 is provided with folding lines, cutting lines, and the like in advance in portions that become the inclined portion 11a and the gripping portion 19 in the state of use, and the user 100 can follow the folding lines and the like to fold the exterior container. By bending the container 10, the inclined portion 11a, the grip portion 19, and the like can be formed. Further, the inclination angle of the inclined portion 11a is preferably an angle corresponding to the inclination angle of the inclined seal portion 20f of the inner container 20 accommodated therein, for example, about 45°, preferably 30° to 60°, and 40°. ° to 50° is more preferred.

When viewed from the rear side (rear side) of the outer container 10 (see FIGS. 2A(e) and 2B(e), etc.), the grip portion 19 is formed near the center of the outer container 10 in the height direction. It has become. By providing the gripping portion 19 near the center in the height direction in this way, even when the weight of the inner container 20 accommodated inside the outer container 10 changes, the user 100 can hold the handle with little force. , the packaging box 1 can be gripped, lifted, and carried with good balance.

The gripping portion 19 has a shape in which a rectangular portion and a semi-elliptical portion (substantially trapezoidal portion) are combined as a whole. The rectangular portion serves as a handle portion for the user 100 to grip, and the semi-elliptical portion serves as a support portion for supporting the inner container 20 accommodated inside from both sides and the rear side (Fig. 2B (f), etc.). reference). Since the inner container 20 is supported by the semi-elliptical portion in this manner, the contents can be easily poured out. That is, when the outer container 10 is tilted, the inner container 20 accommodated in the outer container 10 may move or wobble inside the outer container 10, or the spout portion 21 may become loose and displaced. This makes it possible to prevent the contents from slipping, making it easier to pour out the contents. In addition, since the inner container 20 does not move inside the outer container 10 and the position of the inner container 20 is stable, the container is easy for the user 100 to hold.

The attachment 30 detachably attached to the inclined portion 11a of the outer container 10 will be described with reference to FIG. 3A. The attachment 30 is a thin plate-shaped member having a rectangular shape as a whole. The four corners of the attachment 30 are chamfered and rounded. An insertion portion 30a is provided with a notch extending from the vicinity of the center of the upper side of the attachment 30 toward the bottom side when viewed from the front (FIG. 3A(a)), and the insertion spout portion 21 of the inner container 20 is inserted through the insertion portion 30a. It's becoming

The insertion portion 30a has a shape in which the width of the notch gradually narrows from the top side of the attachment 30 toward the bottom side thereof, and the vicinity of the end portion of the notch is a spout inserted through the insertion portion 11c. It is an engaging portion 30b that engages with the portion 21, and the pouring spout portion 21 is locked. That is, the extraction spout part 21 is engaged with the attachment 30 by fitting the extraction spout part 21 into the engaging part 30b, and is fixed.

Further, as described above, the engaging portion 30b has a tapered shape in which the width gradually narrows toward the bottom side of the attachment 30. It is determined according to the size of the pouring spout portion 21 . For example, the width of the inserting portion 30a near the entrance is about 16 mm, and the width of the engaging portion 30b is about 14.5 mm and about 0.72 mm in descending order. In this way, by using the attachment 30 in which the size of the engaging portion 30b changes, one attachment 30 can be prepared for a plurality of types, for example, pouring spout portions 21 of different sizes. becomes possible.

Furthermore, a protrusion 30c is provided on the rear side of the attachment 30 so as to extend substantially vertically upward with respect to the surface of the rear side (see, for example, FIG. 3A(b)). The protrusions 30 c are provided at the four corners of the attachment 30 . The height of the protrusion is about 5 mm, but is not limited to this. The projecting portion 30c is inserted into a receiving hole 11b, which is provided in the front portion 11 of the outer container 10 and will be described later.

The tip of the protrusion 30c is provided with a spherical portion having a diameter larger than that of the main body of the protrusion 30c and the receiving hole 11b, so that the protrusion 30c inserted into the receiving hole 11b does not come off easily. It has become. That is, the spherical portion provided at the tip of the protrusion 30c serves as a retaining structure for preventing the protrusion 30c from coming off, so that the protrusion 30c does not easily come off from the receiving hole 11b. The size of the spherical portion is determined according to the size of the receiving hole 11b and the like.

Incidentally, the attachment 30 as a whole has a size of about 46 mm×about 54 mm in length and width, and a thickness of about 2 mm. Also, the attachment 30 is made of a member such as plastic or resin, but is not limited to these sizes and materials.

Next, a modification of the attachment 31 will be described with reference to FIG. 3B. The attachment 31 shown in the figure differs from the attachment 30 shown in FIG. 3A in that the width from the insertion portion 31a to the engaging portion 31b is the same. Other than that, it has the same configuration as the attachment 30 shown in FIG. 3A.

The insertion portion 31a has a groove shape with the same width from the top side to the bottom side of the attachment 31, and an engaging portion 31b is provided near the end portion on the bottom side of the insertion portion 31a. The pouring spout portion 21 is inserted through the insertion portion 31a, and the pouring spout portion 21 is fitted into the engaging portion 31b, so that the pouring spout portion 21 is locked and fixed to the attachment 31. become.

Although the attachment 31 shown in FIG. 3B has two protrusions 31c, the number of protrusions 31c is not limited to this, and may be three or more. In addition, although two protrusions 31c are provided at the same height position from the bottom side of the attachment 31, for example, one is provided at the bottom side and the other is provided at the upper side (diagonal position). good too. Since the attachment 31 has a simple structure, mass production is easy. At least one attachment 30 , 31 may be attached to the exterior container 10 .

Next, with reference to FIG. 3C, the engagement relationship between the pouring spout portion 21 and the attachments 30, 31 will be described. First, the pouring spout part 21 has a pouring part 21a for pouring out the filled content and a spout part 21b. The pouring spout portion 21 is attached to the inner container 20 . The pouring portion 21a serves as a pouring port through which the content is poured, and is formed continuously and integrally with the spout portion 21b so as to be supported by the spout portion 21b. A flange portion 21c, which is a member projecting radially outward from the spout portion 21b, is provided on the outer peripheral surface of the spout portion 21b.

The flange portion 21c of the spout portion 21 is engaged with the attachments 30 and 31 so that the spout portion 21 is fitted to the attachments 30 and 31 and fixed. A cap 21d is screwed to the spout portion 21 for closing and opening the spout portion 21a.
