Description

[Detailed description of the invention] This invention consists of a storage container with an exterior made of paper;
In particular, a soft plastic inner bag equipped with a spout portion having a spout is housed inside the outer case, and
This invention relates to a storage container that is attached to an exterior body with a spout portion of an inner bag taken out from the exterior body.

For example, as an inner bag storage container with spout,
The one described in Publication No. -82379 is known.
In this storage container, first of all, in order to attach the spout part to the exterior body, a caulking ring is screwed to the spout part. As a result, the appearance deteriorates and the following drawbacks are pointed out.

That is, the cap is also screwed to the spout, and the cap and the caulking ring are disposed adjacent to each other. For this reason, it has been pointed out that the operator may think that the caulking ring is part of the cap and unscrew it. Due to such an erroneous operation, the outer body is partially disassembled, and the operator must therefore put the caulking ring back into place. In this way, even if it is the operator's own fault, there is a risk that the operator will feel uncomfortable, resulting in poor operability.

Furthermore, it is impossible to attach the caulking ring to the spout unless the caulking ring is rotationally driven. Regarding this point, by appropriately selecting the amount of rotation of the caulking ring, the spout can be more firmly attached to the exterior body, but on the other hand, when automating assembly, this rotational drive complicates automatic assembly equipment. As a result, it takes time to assemble, and thus the assemblability is poor. Furthermore, such complicated assembly equipment is expensive, and as a result, it is an obstacle to reducing the cost of storage containers.

This invention was made in view of the above-mentioned circumstances, and the purpose of this invention is to provide a storage container that has excellent operability and ease of assembly, and can reduce costs.

Hereinafter, one embodiment of the storage container according to the invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, an embodiment of a storage container 10
The exterior body 12 is assembled into a box shape from a piece of cardboard, for example, corrugated paper, and the exterior body 12 is housed with a spout portion 14 taken out to the outside, and is made of soft plastic. An inner bag 16 (shown in FIG. 2), a cap 20 that releasably closes the spout 18 of the spout 14, and a caulking ring 22 for fixing the spout 14 to the exterior body 12. .

First, the exterior body 12 will be explained with reference to FIG. 3.

This exterior body 12 has a shape in which the front upper edge of a square prism is cut out with an inclined surface of approximately 45° over the entire surface, and is made from a single corrugated cardboard exterior substrate 23 shown in FIG. 3A. As shown in FIG. 3B, it is assembled into an intermediate body 24 with an open top.
Therefore, the upper opening of this intermediate body 24 is located at the front edge 12.

Ld′ and the total length (Lb ₁ +Lb ₂ ). This rear flap 26b has a fold line 12g at a length Lb ₂ from the rear edge 12b.
Further, a circular insertion hole 30 into which the spout portion 14 is inserted is formed in the center of the rear flap 26b.

On the other hand, the left and right side walls 24 of the intermediate body 24 are
c, 24d have left and right side flaps 26c, 2
6d are attached to each other in a bendable manner. In addition, the left and right inclined side edges 12e, 12
Left and right inclined flaps 26e and 26f are integrally attached to left and right side walls 24c and 24d of the intermediate body 24 so as to be bendable, respectively, with f as a bending line. Left and right side flaps 26
c and 26d have lengths Lc and Ld that are equal to the width W12 of the exterior body 12, respectively.

Here, the above-mentioned recess 28 has a width W28 sufficient for its both side edges to hold both sides of the spout part 14 when the spout part 14 is inserted therein. Therefore, the left and right upper edges of the front flap 26a separated by the recess 28 have a width corresponding to (W12-W28)÷2.
Will have W26a. Further, each of the left and right inclined flaps 26e and 26f has a width W26e that is the same as this width W26a. Therefore, when the intermediate body 24 is assembled into the exterior body 12, the respective side edges of the left and right inclined flaps 26e are aligned with the front flap 26.
This corresponds to both side edges defined by the recess 28 of a. In other words, when assembled, the left and right inclined flaps 26e, 26f are
The front flap 26a is designed to fully support the portions on both sides of the recess 28 from behind.

In addition, locking flaps 26g, 26h are provided at the center of the front edges of the left and right side flaps 26c, 26d.
are attached to each other so that they can be bent. Both locking flaps 26g and 26h are arranged so as to overlap each other and close the entrance of the recess 28 when assembled. That is, each locking flap 26g, 26h has a width W26g, W26h, which is the same as the width W28 of the recess 28, respectively.
Furthermore, each of the locking flaps 26g, 26h has a length sufficient to lock the spout portion 14 inserted into the recess 28 when assembled. Since both the locking flaps 26g and 26h are provided in this way, the spout portion 1 inserted into the recess 28
4 is locked from all sides, and as shown in FIG. 4, the spout portion 14 is fixed at the inserted position.

Next, the spout portion 14 and the caulking ring 22 will be explained with reference to FIGS. 5 and 6.

The spout part 14 is connected to a base 32 whose plane is oval-shaped.
, an insertion section 34 having a square planar shape erected at the center of the surface of this base 32 , and a first cylindrical body 36 erected at the center of the surface of this insertion section 34 .
A second cylindrical body 3 is provided coaxially with the upper surface of the first cylindrical body 36 and has a smaller diameter than the first cylindrical body 36.
8. base 32, insertion part 34,
A through hole 40 is formed penetrating the first and second cylindrical bodies 36 and 38, respectively. This through hole 4
0 is defined as the above-mentioned spout 18. A male thread is provided on the outer peripheral surface of the second cylindrical body 38, and the cap 20 is screwed thereto.
When the cap 20 is not attached, the internal space of the inner bag 16 is communicated with the outside through the spout 18, and the liquid inside the inner bag 16 is poured out to the outside through the spout 18. . Further, by screwing the cap 20 onto the second cylindrical body 38, the spout 18 is closed and the inner bag 16 is sealed.

On the other hand, the insertion portion 34 is inserted into the recess 2 of the intermediate body 24.
8, and has the same length on each side as the width W28 mentioned above.
a, and a thin plate portion 34b having a length on each side longer than the width W28. The prismatic portion 34a has a height equivalent to two sheets of cardboard forming the exterior body 12.
In this way, the lower surface of the thin plate portion 34b and the base 32
A front flap 26a defining both sides of the recess 28 and left and right inclined flaps 26e, 2 are provided between the upper surface and the front flap 26a.
The overlapped portion with 6f is now held. Further, around the upper part of the outer circumferential surface of the first cylinder 36, three locking pieces 42a, 42b, 42c, which serve as one engaging part, are arranged at equal intervals along the circumferential direction in the radial direction. It is attached so that it protrudes along the side. The upper surface of each locking piece 42a, 42b, 42c is tapered downward.

The caulking ring 22 also includes a cylindrical main body 22a having an insertion hole through which the first and second cylindrical bodies 36 and 38 of the spout portion 14 can be inserted, and this main body 22a.
It integrally includes a skirt portion 22b that is gently curved diagonally downward from the upper edge, and a flange portion 22c as the other engaging portion that protrudes radially inward from the lower edge of the inner peripheral surface of the main body 22a. There is. Here, the lower edge of the skirt portion 22b is located at the same level as the lower edge of the main body 22a. Further, the inner circumferential surface of the main body 22a has a diameter slightly larger than the diameter of the circle connecting the tips of the locking pieces 42a, 42b, and 42c, and the circle formed by the tips of the flange portion 22c is , 42b, 42c. Therefore, when the caulking ring 22 is inserted so that the spout portion 14 enters therein, the flange portion 22c of the caulking ring 22 is aligned with the taper of the locking pieces 42a, 42b, 42c, as shown in FIG. It is once pushed radially outward along the surface by its elasticity, returns to its original state when it enters below the locking pieces 42a, 42b, 42c, and the locking pieces 42a, 42
The upright surfaces defined as the lower surfaces of b and 42c and the upright upper surface of the flange portion 22c engage with each other, and removal of the caulking ring 22 from the spout portion 14 is prohibited.

Note that the distance H1 between the lower surface of the thin plate portion 34b of the insertion portion 34 and the lower surface of each of the locking pieces 42a, 42b, and 42c is the
height H2 and the thickness of the cardboard forming the exterior body 12
This value is slightly shorter than the sum of H3 and H3. By setting each height in this way,
A caulking ring 22 is attached to the spout portion 14,
With the flange portion 22c of the caulking ring 22 engaged with each locking piece 42a, 42b, 42c, the front flap 26a inserted into the insertion portion 34 and the left and right inclined flaps 26e, 26f are stacked one on top of the other. The rear flap 26b is firmly held between the cardboard and the skirt portion 22b of the caulking ring 22.

The assembly operation of the storage container 10 configured as described above will be explained.

First, the inner bag 16 is inserted into the intermediate body 24 shown in FIG. 3B through the upper opening with the spout portion 14 taken out to the outside. After insertion, the left and right inclined flaps 26e and 26f are each folded inward, and then the front flap 26a is folded onto the left and right inclined flaps 26e and 26f. In this way, both sides of the recess 28 are covered with two pieces of cardboard, namely the front flap 26a and the left and right inclined flaps 26e, 26.
f are overlapped. Spout part 1 with cap 20 removed in this state
4 insertion portions 34 are inserted into the recesses 28.
Here, since the two sheets of cardboard are held in the insertion portion 34, the exterior body 12 can exhibit sufficient strength even without reinforcing both sides of the recess 28 with other reinforcing members. Therefore, even if an unreasonable force is applied to the spout portion 14, the spout portion 14 will not be removed from the exterior body 12.

Thereafter, the left and right side flaps 26c, 26d are each folded inward and overlapped. In this way, the upper opening of the intermediate body 24 is closed. In addition, these left and right side flaps 26c, 26
d are overlapped, both locking flaps 26
g and 26h are also overlapped and located in the center. Both of the locking flaps 26g and 26h are bent inward so that their tips end at the upper insertion portion 34 of the spout portion 14, as shown in FIG.
It is inserted into the part. In this way, the spout part 14 is surrounded on all sides, and even if force is applied to the spout part 14 from any direction, the spout part 14 maintains its position well and there is no fear of it shifting.

Thereafter, the rear flap 26b is folded inward, and the spout portion 14 is inserted into the insertion hole 30 and placed on the front flap 26a.

After this condition is achieved, the caulking ring 22 is attached to the spout portion 14. That is, the caulking ring 22 is simply inserted along the axial direction of the spout portion 14 . Along with this insertion, the flange portion 22c of the caulking ring 22 engages with each locking piece 42a, 42b, 42c of the spout portion 14, and is fixed to the spout portion 14, and at the same time, the flange portion 22c of the caulking ring 22 is fixed to the spout portion 14. The peripheral edge of the skirt portion 22b presses the rear flap 26b, and the assembly work of the exterior body 12 is completed.

Here, as can be easily understood from the above explanation, there is no need to rotate the caulking ring 22 when installing it, and it is sufficient to simply push it along the axial direction of the spout portion 14. Therefore, the assembly operation is simplified, and even if it is automated, there is no risk of complicating the automatic assembly device, and costs can be reduced. Furthermore, it is extremely difficult to remove the caulking ring 22 attached to the spout portion 14, and there is no risk that the inside of the exterior body 12 will be exposed.
are well protected. Furthermore, even if the operator accidentally rotates the caulking ring 22 thinking that it is part of the cap 20, the caulking ring 22 will simply rotate in that position and the flange portion 22c of the caulking ring 22 and the spout will Each locking piece 4 of part 14
2a, 42b, and 42c are not released, and the caulking ring 22 is not removed from the spout portion 14. In this way, good operability is achieved. The skirt portion 22b of the caulking ring 22 is formed with a smooth curve, and is aesthetically pleasing without causing any discomfort to the operator.

After the exterior body 12 has been assembled in this way, a desired liquid is injected into the inner bag 16 through the spout 18, and then the cap 20 is attached to the spout 14 and the spout 18 is opened. blocked,
A series of operations for assembling the storage container 10 is completed.

This invention is not limited to the configuration of the one embodiment described above, and can be modified in various ways without departing from the spirit of this invention.

For example, in one embodiment described above, the locking flap 2
6g, 26h on the left and right side flaps 26c, 26
I explained that they should be attached to each section. However, without being limited to such a configuration,
For example, the locking flaps 26g, 26h may be attached to the upper portions of the side edges of the left and right inclined flaps 26e, 26f.

Further, the number of locking pieces 42a, 42b, 42c is 3.
The locking piece is not limited to this, and any number of locking pieces may be used as long as it is plural, and the locking piece may be formed in an annular shape. Here, when the locking piece is formed in an annular shape, the member that can be engaged with this may be a flange portion, or a plurality of protrusions that can be engaged with the annular locking piece. It's okay. Further, the tapered surface does not need to be attached to the engagement piece, but may be attached to the flange (protrusion) on the caulking ring side, or may be attached to both.

Furthermore, during assembly, a desired liquid may be injected into the inner bag 16 in advance, and then sealed with the cap 20 and stored in the intermediate body 24. Further, the cap 20 is not limited to being screwed to the spout portion 14, but may be any mechanism capable of sealing the inner bag 16, such as a snap connection.

As described in detail above, the storage container according to the present invention includes an exterior body having a rear flap in which a through hole is formed and a front flap in which a recess is formed, and is housed within this exterior body, and the spout portion is It is equipped with an inner bag taken out to the outside through a recess and a through hole, and a caulking ring for fixing the spout part to the exterior body, and the spout part is inserted into the recess, and the inserted spout part By folding the rear flap so that it overlaps the front flap so that it is inserted into the through hole, and attaching the caulking ring to the spout part, the rear flap is fixed onto the front flap and the spout part is secured to the exterior body. In the storage container, the caulking ring has an insertion hole into which the spout is inserted, and an engaging portion that engages with each other is formed on an inner surface defining the insertion hole and an outer surface of the spout. Each of the engaging portions has at least one tapered surface that allows the caulking ring to be inserted into the spout along the axial direction of the spout, and an upright surface that maintains the engagement. The crimping rings are characterized in that in their mutually engaged state they press the rear flap onto the front flap. Therefore, according to this invention, there is provided a storage container that is excellent in operability and assemblability and can be manufactured at low cost.
