Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container in which a spout of an inner bag (also used as a spout, also referred to as a spout) is attached through an inner flap, such as a cardboard box in which the inner bag is stored in advance. The present invention relates to an assembly container having a cap-attached spout of an inner bag, the upper surface of which is assembled flat so that the cap does not interfere with the stacking of the upper container.
[0002]
[Prior art]
Since it is extremely difficult to pack the contents in the inner bag and then put it in the container, conventionally, in the bagging corrugated cardboard box of the fluid, one in which the inner bag is set in advance is used. According to this, the contents are injected and poured out from the spout while the outer flap is protruded through the inner flap and the outer flap is opened.
[0003]
[Problems to be solved by the invention]
However, in this type of container, since the spout and the cap protrude above the inner flap, the outer flap cannot be closed flatly by supporting it, so that the upper container cannot be stably stacked. There was a problem.
[0004]
Conventionally, in order to solve the above-mentioned problem, the spout is formed so that the inner side surrounded by the peripheral edge is low as a concave portion in which the cap is accommodated, and a cylindrical opening for screwing the cap into the central portion of the concave portion is protruded. It was configured to be fitted low in order to fit in. However, according to this, since the spout is lowered, it is difficult to sprinkle other containers when the contents are poured out, and there is a problem that dripping occurs because the discharge momentum cannot be obtained. When viewed from the inside, the concave portion of the spout is convex, which obstructs the dispensing of the contents, which makes it easy for the contents to be left behind at the end. There was a problem with it.
[0005]
In view of the above situation, the present invention is designed so that the cap does not hinder the stacking of the upper container even if the spout is formed so as to protrude from the inner flap so that the contents can be easily poured out. An object of the present invention is to provide an assembly container provided with a cap spout with an inner bag, the upper surface of which is flush and the contents can be taken out and the cap can be easily attached and removed.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention comprises an assembly container of a type whose upper end is closed by overlapping an outer flap on an inner flap, and an inner bag having a cap outlet with a cap protruding from the upper end. A spout is attached through the inner flap, and a cut is provided in the inner flap or both the inner flap and the face wall on which the inner flap is protruded so that the inner flap is folded below the ruled line. In the assembly container formed as a horizontal drop piece that is lowered at a distance from the outer flap by forming a fold line of the drop piece on the outer flap, the following (a), (b), (c ) Configured either.
[0007]
(A) The incision is vertically formed over both the inner flap and the face wall, and two folding lines are provided so that a part of the dropping piece is formed obliquely, and the dropping piece of the attachment portion of the spout is horizontal. An assembly container provided with a spout with a cap of an inner bag, wherein at least one folding line is formed below a ruled line on which an inner flap is folded so as to be folded. (Claim 1)
(B) The vertical cut is one or two strips reaching the tip of the inner flap, and at the tip of the drop piece, a horizontal mountain fold line connected to the tip of the cut and a width from the base end to it. An assembly container having a cap spout with an inner bag characterized in that a falling piece is formed as a support piece that forms an L shape from the inner flap between the two folding lines. . (Claim 2)
(C) While forming a vertical score line on the inner flap and the face wall closer to one side than the width center portion, a cutout is provided in the outer flap and the side wall adjacent to this, and the vertical score line An assembly container provided with a spout with a cap of an inner bag, characterized in that a drop line is formed at one end by providing a folding line from the lower end to the notch. (Claim 3)
[0008]
According to the above configuration, if the drop piece is lowered to about the protruding height of the cap by cutting, the cap becomes lower so that it does not become an obstacle as a convex to stack the upper container, As a result, the spout can be formed in a protruding form without dripping. Moreover, since the drop piece comes out by manual operation or due to internal pressure at the time of pouring (becomes a restored state, a further protruding state, or a state close to the restored state depending on the form), the convexity inside the container is Since the state is eliminated, the contents are not left behind. In addition, the cap can be easily attached and removed as with an ordinary cap.
[0009]
When the drop piece is formed only by the cut line (see the first embodiment), the restoration is easy, but when the fold line is added ( see other embodiments ), the drop piece is conveniently and aesthetically pleasing. Can be leveled. In particular, according to the second aspect, the falling piece is held in a horizontal state by the support piece.
[0010]
According to the fourth aspect of the present invention, since the reinforcing plate acts to open the inner bag toward the spout, it is easy to inject it when the contents are put.
[0011]
Further, since the container can be folded back and forth symmetrically when configured as in claim 5 , even if the inner bag is adhered to the front and rear surfaces or each surface of the inner periphery of the container, the inner bag adapts to folding and assembly. Because it opens and closes without hindrance, it is easy to inject the contents.
[0012]
Moreover, when comprised like Claim 6 , the form which an up-and-down hook pinches | interposes the edge of an attachment hole is obtained, and the firm attachment state of a spout is obtained.
[0013]

[0020]
【Example】
Next, some typical embodiments of the present invention will be described with reference to the drawings.
[0021]
In any of the embodiments, the assembly body 1 includes an assembly box 1 as a container body and an inner bag 2 accommodated therein, and a spout 3 with a cap 4 is integrally attached to the inner bag 2. The assembly box 1 is particularly preferably an A-type cardboard box, but is not limited thereto. In this assembly box 1, front and rear wall surfaces 7, 7 and left and right side walls 8, 8 alternate, inner flaps 9, 9 at the upper ends of front and rear surface walls 7, 7, and outer flaps 10, 10 at the upper ends of left and right side walls 8, 8. Each projectes. Reference numerals 9a and 10a denote the respective folding ruled lines. In addition, it has the inner flaps 11 and 11 and the outer flaps 12 and 12 similarly at a lower end (refer FIG. 4, FIG. 7). And the spout 3 is penetrated by the inner flap 9 of a piece of upper end, protrudes on the upper surface, The attachment part is formed as the drop piece 5. FIG.
[0022]
FIG. 1 and FIG. 2 show the first embodiment. In one piece of the inner flap 9, two vertical cuts 13 and 13 are formed so as to divide it into three pieces, and the central piece is dropped. As 5, a spout 3 was attached thereto. In this case, when the outer flaps 10, 10 are folded on the inner flaps 9, 9 as a lid tightening, the cap 4 is pressed and is pushed under the outer flap 10 with the elastic deformation of the falling piece 5 being bent.
[0023]
In the case of the figure, mountain fold folding lines 17, 17 bent outward are formed at the center of the width between the left and right side walls 8, 8 and the outer flaps 10 at both upper and lower ends so that the assembly box 1 can be folded symmetrically. The inner bag 2 is formed and is easily attached to the folding, and is adhered to the front and rear walls 7 and 7.
[0024]
FIGS. 3 to 5 show a second embodiment. In this case, two vertical cuts 13 and 13 are provided in the central portion of the width of the inner flap 9 from the vicinity of the upper end, and the face wall 7 is formed. The cuts 13 and 13 are formed so as to extend to the upper end and to be shorter than the ruled line 9a. Further, a separate horizontal cut 14 is provided to connect the upper ends of both cuts 13 and 13, and a fold line 15 is provided to connect the lower ends. A piece bent by 15 is a drop piece 5. Therefore, the drop piece 5 can be horizontal at the height of the folding line 15 (FIG. 5).
[0025]
Further, the ruled line 9a is left at the base end portion of the drop piece 5, and the drop piece 5 is easily restored due to the remaining ruled line 9b. Further, the outer flaps 10 and 10 are formed with perforated cut lines 18 and 18 for cutting the contact of the cap 4. This prevents unauthorized opening in the distribution process and facilitates opening.
[0026]
The spout 3 has upper and lower flanges 3a and 3b that obstruct the penetration of the mounting hole 6 between the edges of the mounting hole 6. Therefore, the mounting of the spout 3 from the circular portion of the mounting hole 6 to a pair of tangential grooves 6a and 6a A temporary folding line 6b connecting the ends is formed in the drop piece 5 so that a portion surrounded by them can be opened once.
[0027]
FIGS. 6 to 8 show a third embodiment. In this case, a single longitudinal cut line 13 is formed on the inner flap 9 and the face wall 7 closer to one side than the width center. A notch 19 is provided in the outer flap 10 and the side wall 8 adjacent to each other, and a folding line 15 is provided from the lower end of the vertical notch 13 to the notch 19 so that a drop piece 5 is formed at one end.
[0028]
Therefore, in the case of this embodiment, the spout 3 of the inner bag 2 is attached to the corner, and the cap 4 is housed in the notch 19. The notch 19 is expanded in a circular shape so that the cap 4 can be removed while the outer flaps 10 and 10 are sealed. Moreover, the side edge 5a of the drop piece 5 is hooked on the lower end edge 8a of the notch 19, so that the drop piece 5 is not lowered.
[0029]
FIG. 9 and FIG. 10 show the fourth embodiment, in which two vertical cut lines 13 and 13 are provided in the center portion between the inner flap 9 and the face wall 7 and are connected between the lower ends thereof. The tip 15 of the drop piece 5 is continuous with the inner flap 9 via the valley fold fold line 15a and the mountain fold fold line 15b. A space between the folding lines 15a and 15b is formed as a support wall 21 that keeps the tip of the drop piece 5 from being lowered. In that sense, it can be said that the second embodiment (FIGS. 3 to 5) is developed.
[0030]
Further, the inner bag 2 is made of a plastic film, and is bonded only to the front wall 7. In this state, the lower part of the spout 3 is blocked by the rear part of the inner bag 2 being in close contact with the front part of the bonding. Then, a cardboard reinforcing plate 22 is bonded to the rear part, and the folding line 15 is bent when the falling piece 5 is formed, so that both ends of the reinforcing plate 22 bonded so as to intersect the folding line 15 are respectively connected to the falling piece 5 and the face wall 7. In this case, the reinforcing plate 22 is pushed back inward by its rigidity, so that a triangular space is formed, so that the contents can be easily injected (see the two-dot chain line in FIG. 10). In this case, the cap 4 is sealed from the outer flaps 10 and 10 so that the cap 4 cannot be opened illegally, but has an opening 20 on the front surface.
[0031]
In addition, the spout 3 is attached in an L shape. Since it is L-shaped and the spout 3 is not cut off, the spout 3 is strong and can be pulled strongly or pushed down when it is poured out. Therefore, when pouring out / in, the pouring outlet 3 is used in a state where it is strongly pulled out, so that the contents can be easily poured out without being attached around the container.
[0032]
On the other hand, by pushing up and dropping the drop pieces 5 into the L shape, stacking becomes possible during transportation and storage. In addition, the L-shaped shape can be easily formed into an L-shaped shape by making the mountain-folded folding line 15a into a grooved ruled line and the valley-folded folding line 15b into a half-cut ruled line.
[0033]
In the fifth embodiment (FIGS. 11 and 12), ear pieces 23 and 23 for sealing the opening 20 are provided on one side end of the upper end portions of the outer flaps 10 and 10 through folding lines 25 and 25, respectively. As a result, the cap 4 is completely sealed without being visible, and if it is sealed with tape or the like, fraud in the distribution channel is completely prevented.
[0034]
FIGS. 13 and 14 show a sixth embodiment. In this case, the falling piece 5 is formed in a form similar to that of the second embodiment (FIGS. 3 to 5), but it is bent. A fold line 15 at the lower end is formed with a level difference m of the thickness of the corrugated cardboard, and the tip of the drop piece 5 is hooked as a claw portion 27 on the cut edge 29 of the inner flap 9 so as not to move upward.
[0035]
Further, notches 31, 31 are provided at the upper corners of the outer flaps 10, 10, so that the cap 4 is exposed from the combined opening of the notches 31, 31 (FIG. 14). Therefore, in this embodiment, the cap 4 can be opened and closed with the outer flaps 10 and 10 sealed. The upper end of the cap 4 is set to be almost the same height as the upper surface of the outer flap 10.
[0036]
Although not shown in the drawings, the seventh embodiment will be described with reference to FIG. 1 of the first embodiment. When the valley-folded folding line 18 is provided at the base end of the drop piece 5, the drop piece 5 is stepped and flattened. Can be made.
[0037]
15 and 16 show still another embodiment in which a folding line 15 at the lower end and a mountain folding line 15c near the circular mounting hole 6 are formed so that the base end portion 5a of the dropping piece 5 forms a slope. Yes. Thus, in this embodiment, the notch 13 is vertically formed over both the inner flap 9 and the face wall 7, and the two folding lines 15 and 15 c are provided so that a part of the drop piece 5 is formed obliquely. At least one of the fold lines forms a fold line 15 of the drop piece 5 below the ruled line 9a where the inner flap 9 is folded so that the drop piece 5 of the attachment portion of the spout 3 can be folded horizontally. It is.
[0038]
The container of this embodiment is conveniently used in the following cases. That is, in recent years, in-can color matching is performed in a container for transportation in order to cope with a small lot or a wide variety of products when the content is a paint or the like. In this method, a pigment is put into a can and the can itself is stirred. At this time, the corner portion of the container is difficult to mix, so it is desirable to make the corner easy to mix. This embodiment container is optimal for exactly the above purposes.
