Abstract

PROBLEM TO BE SOLVED: To prevent the liquid in a container from contacting with a metal member and, prevent the contents-liquid from deteriorating. SOLUTION: The head of a container is formed from an aluminum laminate plate 4, and a score 5 is formed on the outside of the container-opening part 49 of the aluminum laminate plate 4. A push piece 2 is arranged in a discharging cylinder 50a, and consists of a horizontal part 2a which is parallel to the aluminum laminate plate 4 and a vertical part 2b which is connected with one end of the horizontal part 2a and perpendicular to the aluminum laminate plate 4. By pushing the push piece 2 toward the inside of the container, the contact part 2d of the push piece 2 presses the aluminum laminate plate 4, so that break goes forward with the score 5 near the contact part 2d as a start point and the container is opened. Because the break does not reach the score opposite the contact part 2d, a broken piece which occurs due to the break is not separated from the opening part. Thus, the broken piece does not fall into the container.

2. Description of the Related Art FIG. 6 is a perspective view showing a conventional general rectangular container 40 with a spout. The container 40 is constructed by folding a single sheet material and assembling it.
A bottom portion 42, a bottom sealing portion 43 for sealing a mating portion of the bottom portion 42, a side wall sealing portion 44 for sealing a mating portion of the side wall 41, a shoulder portion 46 of the head, and a folded portion 45 of the head. , A sealing portion 47 of the head, an opening 49 provided on the shoulder 46 of the head, and an opening plug (cap) 48 for sealing the opening 49. The opening plug 48 is of a screw type, and when the opening plug 48 is turned to be removed, the opening portion 49 is opened and the content liquid can be poured out. In addition, the thin plate material is usually formed of a multilayer plate having 6 or 7 layers. For example, in the case of a 6-layer plate, a polyethylene (PE) layer, a paper layer,
A layer, an aluminum foil, a PET (polyethylene terephthalate) layer, and a PE layer are sequentially laminated and formed.

FIG. 7A is a cross-sectional view showing a first prior art pouring device 50 attached to a container opening portion 49.
(B) is sectional drawing which expands and shows the junction part of the pouring tool 50. FIG. As shown in FIG. 7A, an annular pipe mounting surface 50b is formed below the cylindrical pipe 50a, and the axis of the pipe 50a and the axis of the pipe mounting face 50b are coaxial. Present on. A male screw 52 is formed on the outer surface of the injection tube 50a, and an opening plug 48 shown in FIG. 6 is screwed thereto. A sealing sheet 53 is provided on the lower surface of the cylinder mounting surface 50b.
Is heat-sealed to form a first heat-sealed portion 54a, which prevents the liquid in the container from entering the injection tube 50a. The upper surface of the injection tube mounting surface 50b and the lower surface of the shoulder portion 46 of the head are joined by heat sealing,
A second heat seal portion 54b is formed. This prevents the content liquid from leaking out of the container from the gap between the spouting tool 50 and the container opening portion 49, and prevents outside air from entering the container from this gap.

[0004] When opening the pouring device 50 constructed as described above, first, an opening plug (not shown, shown in FIG. 6) fitted to the pouring tube 50a is loosened and removed. Next, the sheet 53 is broken manually or by a predetermined member. As a result, the spout 50 is opened, and the liquid in the container passes through the inside of the spout 50a and then flows out.

In recent years, there has been proposed an opening plug which is not removed by turning it with a screw, but is designed to be easily opened. FIG. 8 is a cross-sectional view showing a second prior art dispenser attached to a container opening portion (Japanese Patent Application Laid-Open No. 57-77455). As shown in FIG. 8, a bent portion 23b is formed in the opening 28 of the container 23, and the tip 23a of the opening 28 faces the inside of the container. The tip 23a is engaged with the spout 20 so that the spout 20 is fixed to the opening 28. The pouring tool 20 is made of a synthetic resin, and roughly includes a tubular body 22 and a plug-like body 21.

The tubular body 22 is a cylindrical member. To fix the spout 20 in the opening 28, a claw 22a is formed on the lower outer surface, and an annular flange 22b is formed on the upper outer surface. Is formed. While this claw part 22a is in contact with the tip part 23a of the opening part 28 described above,
The aforementioned bent portion 23b is in contact with the lower surface of the flange 22b. For this reason, the claw 22a and the tip 23 of the opening 28
a, and between the lower surface of the flange 22b and the bent portion 23b, the tubular body 22 is fixed to the opening 28. In addition, a concave portion 22c is formed on the inner surface of the lower end of the claw portion 22a, and a disk described later is disposed in the concave portion.

A columnar body 21 is arranged inside the tubular body 22 so as to be coaxial with the tubular body 22. Column 2
Reference numeral 1 denotes a tub-shaped member, the bottom surface of which is closed by a base 21c. At the lower part of the peripheral portion of the base 21c, a convex portion 2 is provided.
1a is provided, and the projection 21a protrudes downward. The convex portion 21a is a member for breaking a disk described later. An annular flange 21 is provided on the upper part of the columnar body 21.
b is formed. Outer diameter of flange 21b and tubular body 2
The outer diameters of the flanges 22b are substantially the same.
A part of the periphery of 1b and a part of the periphery of the flange 22b are fixed to form a fulcrum 29. Flange 21b
The gripping member 25 is located on the side of the
Is attached. Further, a groove 27 is formed on the upper surface of the flange 21b as a starting point of the deformation of the columnar body 21 when the plug is opened. The lower surface of the flange 21b of the columnar body 21 and the upper inner surface of the tubular body 22 are joined to each other to form a ring-shaped joint 26. Thereby, the gripping member 25
When the column is lifted, the columnar body 21 rises around the fulcrum 29, the joint 26 is cut, and the columnar body 21 is
It is designed to be separated from. Further, since the groove 27 is formed, when the gripping member 25 is lifted, the columnar body 21 is deformed with the groove 27 as a starting point, and the convex portion 2 of the columnar body 21 is deformed.
1a is designed to press and break a disc described later.

As described above, the concave portion 22c is formed in the claw portion 22a of the tubular body 22, and the circular plate 24 having substantially the same radius as the inner surface radius of the concave portion 22c is disposed in the concave portion 22c. Further, the vertical depth of the concave portion 22c and the disk 24
Are approximately the same thickness. For this reason, the disk 24
It does not protrude in any of the horizontal direction and the vertical direction, and is fitted into the concave portion 22c. The disk 24 is formed by coating a synthetic resin film 24b on both surfaces of an aluminum foil 24a, and the disk 24 is formed by heating the synthetic resin film 24b by high frequency induction heating.
And the concave portion 22c of the tubular body 22. The plastic film 3 is formed so as to cover both the lower peripheral edge of the disk 24 and the claw 22a of the tubular body 22.
1 are arranged, and the film 31
4 and the claw portion 22a are joined. This prevents the disk 24 from being separated from the claw 22a when the disk 24 is pressed against the protrusion 21a of the columnar body 21.

[0009] The pouring device thus configured is opened as follows. First, grasp the gripping member 25,
Lift up. Then, the columnar body 21 bends around the groove 27 and the columnar body 21
A tensile force acts between and the tubular body 22. Due to this tensile force, the joint portion 26 is broken, and the columnar body 21 becomes rotatable about the fulcrum 29 as a support shaft. At the same time, the convex part 2
1a presses the disk 24, and the disk 24 is broken. Thus, if the columnar body 21 is pivoted up about the fulcrum 29 as a support shaft, the liquid in the container flows out through the broken portion of the disk 24 and the inside of the tubular body 22 to the outside. In addition, the columnar body 21
Although the joint between the tubular body 22 and the columnar body 21 is broken,
Is still joined to the tubular body 22 via the fulcrum 29, so that the columnar body 21 can be fitted to the tubular body 22 again by rotating the columnar body 21 about the fulcrum 29 as a pivot. . Thereby, the deterioration of the content liquid in the container during storage can be prevented.

[0010]

However, the above-mentioned prior art has the following problems. That is, in the first prior art shown in FIG. 7, the sheet 53 needs to be heat-sealed to the lower surface of the cylinder mounting surface 50b.
In the second prior art shown in (1), since the disk 24 needs to be heat-sealed below the tubular body 22 and below the columnar body 21, there is a problem that the process is complicated. In addition, since it is necessary to improve the sealing property before opening and to easily break at the time of opening, the sheet 53 and the disk 24
Has a special structure and has a disadvantage of high cost.

In the first prior art, the cylinder mounting surface 50
If the heat seal between the second heat seal portion 5b and the shoulder portion 46 of the head is insufficient, as shown in FIG.
Outside air enters from 4b, and the content liquid is apt to deteriorate,
There is a problem that the content liquid easily leaks through the second heat seal portion 54b.

In order to avoid this problem, when heat sealing is performed, it is conceivable that the heating time is lengthened and the injection pipe mounting surface 50b and the shoulder 46 of the head are further firmly joined. Can be However, long-time heating causes a decrease in productivity, and also has a disadvantage that the PE layer on the inner surface of the rectangular cylindrical container is deteriorated and odor is generated.

Further, since the first and second heat seal portions come into contact with the content liquid, there is a disadvantage that the odor of each heat seal portion is transferred to the content liquid, particularly when stored for a long time.

Further, there is a drawback that the sheet 53 broken at the time of opening easily falls into the container.

On the other hand, in the second prior art, the tubular body 2
Although the inner surface radius of the concave portion 22c of the second claw portion is substantially the same as the radius of the disk 24, the radius of the disk 24 is slightly larger than the inner surface radius of the concave portion 22c in order to fit the disk 24 into the concave portion 22c. It is getting smaller. Therefore, a gap 32 exists between the concave portion 22c and the disk 24. Although the gap 32 is covered with the plastic film 31, if the bonding between the film 31 and the lower surface of the disk 24 and the claw portion 22a is insufficient, the content liquid comes into contact with the aluminum foil 24a, and There is a problem that the liquid is deteriorated.

The present invention has been made in view of the above problems, and provides a liquid container with a spout which can prevent the contents liquid in the container from contacting the metal member and preventing the contents liquid from deteriorating. The purpose is to do.

[0017]

According to the present invention, there is provided a liquid container with a spout according to the present invention, comprising: a container body formed into a rectangular tube shape having a head and a bottom by a metal plate sandwiched between synthetic resin layers; Opening portion having a score formed by scoring on the head of the container, a cylinder provided on the outer surface of the container body at the opening portion, and a pusher provided in the cylinder and connected to the cylinder. And the push piece is pushed in to break open the opening portion and open.

It is preferable that the score is formed on the outer surface of the container at the opening.

The score extends in an annular shape, and its cross-sectional shape is a concave shape having a bottom portion and side portions provided at both ends of the bottom portion. The sides are inclined so as to be longer than the width of the bottom, and the angle between the sides is 40 to 80 °,
The width of the bottom is preferably 20 to 50 μm, and the distance from the bottom to the inner surface of the container of the stopper is preferably 70 to 120 μm.

It is preferable that the abutting portion of the pushing piece with respect to the opening portion is within a region of 2 mm from the upper end of the inner side of the score.

The thickness of the synthetic resin layer is 20 to 60 μm
It is preferred that

In the liquid container with a spout according to the present invention, the pushing piece is pushed toward the inside of the container body. Then, since the pushing piece presses the opening portion, a crack is generated in the opening portion along the score, starting from the score near the pushing piece, and the breakage proceeds. When the pushing piece is further pushed in, the breakage proceeds further and is opened. The progress of the break depends on the pressing amount and the pressing position of the pushing piece, but usually does not reach the score of the far end of the pushing piece. For this reason, a part of the fragment formed by the break remains connected to the plug opening part, so that the fragment does not fall into the internal solution. When the opening portion is opened in this manner, the content liquid is poured out of the container via the injection tube.

In the present invention, since the injection cylinder is provided on the outer surface of the container main body, the container main body is completely sealed. To
The liquid content does not leak to the outside or the outside air enters the container. For this reason, the content liquid does not deteriorate due to the mixture of outside air. Further, since it is not necessary to form a through hole in the container body as in the prior art and then join a sealing material to this through hole to provide an opening portion, the number of manufacturing steps can be reduced.

Further, since the inner surface of the container body is covered with the synthetic resin layer, the content liquid does not contact the metal plate before opening, but is in contact with the synthetic resin layer. Similarly, the content liquid does not come into contact with the joint between the injection cylinder and the container body before opening. For this reason, the odor and the like of the joint and the metal plate are not transferred to the content liquid, and the flavor and the like are not impaired, and the deterioration of the content liquid can be prevented.

Further, when the score is broken by the indented piece to form a fragment, the fragment does not fall into the content liquid, so that deterioration of the content liquid due to the fragment can be prevented. Further, unlike the sealing material of the related art, the score is broken, so that once opened, it is difficult to return to the original state, and unauthorized opening can be easily found. For this reason, shrink wrapping or the like that wraps the entire liquid container with a sheet is not required.

The above-mentioned score may be provided on either the inner surface and / or the outer surface of the stopper. However, when scoring is performed on the inner surface, the synthetic resin layer on the inner surface side is broken, the metal plate is exposed, and there is a possibility that the metal liquid is deteriorated due to contact with the metal plate. Therefore, it is preferable that the score is provided on the outer surface side of the opening portion.

The score may be, for example, an annular extension on the surface of the opening portion, but is not limited to this. There is no particular limitation on the radius of the ring, for example,
What is necessary is just to set so that it may become smaller than the inside diameter of a injection pipe. On the other hand, the cross-sectional shape of the score is also not particularly limited, and may be various. For example, the cross-sectional shape may be concave, and the distance between the upper ends of the concave portions may be longer than the width of the bottom. In this case, the angle formed by the concave side portions is preferably 40 to 80 °. If the angle between the concave side portions is less than 40 °, the score may break before opening due to the internal pressure of the content liquid, and the content liquid may leak to the injection cylinder side. On the other hand, this angle is 80 °
When it exceeds, the opening property of the plug opening part deteriorates.

The width of the above-mentioned concave bottom is preferably 20 to 50 μm, and the distance (remaining thickness) from this bottom to the inner surface of the container of the opening portion is preferably 70 to 120 μm. When the width of the bottom is less than 20 μm or the remaining thickness is less than 70 μm, the score may be broken due to the internal pressure of the content liquid, and the content liquid may leak to the injection cylinder side. on the other hand,
When the width of the bottom exceeds 50 μm or the remaining thickness is 120 μm
In the case of exceeding, the opening property of the plug opening part is deteriorated.

In order to open the opening portion with as little pressing force as possible, the contact portion of the pushing piece with the opening portion is set within a region 2 mm inward from the upper end of the inner side of the score. Is preferred. Then, the pressing force concentrates on the score closest to the contact portion, and does not disperse throughout the score. As a result, the break starts from one point of the score, and the break proceeds along the score.
The stopper can be opened with a relatively small pressing force.

The thickness of the synthetic resin layer is preferably 20 to 60 μm. If the thickness of the synthetic resin layer is less than 20 μm, there is a possibility that the content liquid comes into contact with the metal plate. On the other hand, when the thickness of the synthetic resin layer exceeds 60 μm, a large score shearing load is required, and the opening property of the plug opening part is deteriorated.

In the present invention, since the container body is formed of a material in which a metal plate such as an aluminum plate is covered with a resin layer, the container can be recycled.

[0032]

Next, an embodiment of the present invention will be described.
This will be specifically described with reference to the accompanying drawings. FIG. 1 is a sectional view showing a liquid container with a spout according to an embodiment of the present invention. In FIG. 1, the same components as those in FIG. 7 are denoted by the same reference numerals, and detailed description thereof will be omitted. As shown in FIG. 1, the head of the container is formed of an aluminum laminated plate 4, and a score (cut portion) 5 is formed on the outer surface side of the container opening portion 49 of the aluminum laminated plate 4 by score processing. Have been. The score 5 extends along a circle whose axis is perpendicular to the aluminum laminate 4 and is coaxial with the circle.
A cylindrical spout 1 is arranged on the outer surface of the aluminum laminate 4. The pouring tool 1 is made of synthetic resin, and the inner diameter of the pouring tube 50a of the pouring tool 1 is larger than the outer diameter of the above-mentioned circle. The injection cylinder mounting surface 50b of the injection tool 1
And the aluminum laminate 4 is heat sealed,
A heat seal portion 7 is formed.

The pushing piece 2 is arranged in the injection tube 50 a, and the pushing piece 2 is a horizontal portion 2 parallel to the aluminum laminated plate 4.
a connected to one end of the horizontal portion 2a
And a vertical portion 2b perpendicular to the vertical axis. Horizontal part 2a
Is connected to the inner surface of the injection tube 50a so that the pushing piece 2 does not separate from the injection tube 50a when the stopper is opened.
A sharp portion 2c is formed at the lower end of the vertical portion 2b, and when the pushing piece 2 is pushed toward the inside of the container,
A high pressure is applied to the container opening part 49. Although the position of the abutting portion 2d of the sharp portion 2c with respect to the container opening portion 49 is not particularly limited, the abutting portion 2d is usually within a region 2 mm inward from the upper end 5a of the inner side of the score 5. That is, the distance L is set to be within 2 mm.

FIG. 2 is an enlarged sectional view showing the score 5 of the container opening portion 49. As shown in FIG. 2, the aluminum laminated plate 4 is formed of an aluminum alloy plate 4b and synthetic resin layers 4a and 4c joined to the inner and outer surfaces of the aluminum alloy plate 4b, respectively. The thickness of the synthetic resin layers 4a and 4b is set, for example, in the range of 20 to 60 μm. The cross-sectional shape of the score 5 in the plane including the axis is a trapezoidal concave shape, and the distance between the side upper end 5a and the side upper end 5f of the score 5 is different from that of the synthetic resin layer 4.
It is longer than the width of the bottom 5c on the c side. The intersection angle θ between the sides 5b of the score 5, the width W of the bottom 5c, and the bottom 5
Although the distance (remaining thickness) D between c and the synthetic resin layer 4b is not particularly limited, the intersection angle θ is 40 to 80 °, the bottom width W is 20 to 50 μm, and the distance D is 70 to 1
It is preferably 20 μm.

In the thus constructed liquid container with a spout, an opening plug (not shown, shown in FIG. 6) is firstly screwed into the external thread 52 of the injection tube 50a. After loosening the opening plug and removing it from the filling tube 50a, the pushing piece 2 is pushed into the inside of the container manually or by a predetermined member. Then, when the contact portion 2d of the pushing piece 2 presses the aluminum laminated plate 4, a crack is generated starting from the score 5 near the contact portion 2d. When the pushing piece 2 is further pushed in, the breaking progresses from the vicinity of the abutting portion 2d according to the score 5 by the principle of leverage, and a broken piece 6 is formed as shown in FIG. However, since the fracture starts to progress from the vicinity of the contact portion 2d, the farthest score 5e of the contact portion 2d (the contact portion 2d).
d). Therefore, the debris 6
Remains connected to the aluminum laminate through the distant score 5e and does not fall into the container. By forming the fragments 6, the container is opened, and the liquid in the container passes through the injection tube 50a and is discharged to the outside.

Since the spout 1 is installed on the outer surface of the container, even if the heat seal 7 between the lower surface of the spout mounting surface 50b of the spout 1 and the aluminum laminate 4 is incomplete,
Since the outside air does not enter the container before opening, there is no possibility that the content liquid is deteriorated due to the mixing of the outside air, and the content liquid does not leak outside. In addition, the content liquid does not come into contact with the heat seal portion 7 before opening, and does not come into contact with the aluminum alloy plate 4b of the aluminum laminate 4. For this reason, the odor of the heat seal portion 7 and the aluminum alloy plate 4b does not transfer to the content liquid, and the deterioration of the content liquid can be prevented. In addition, since the fragments 6 do not separate from the aluminum laminate 4, they do not fall into the content liquid, and it is possible to prevent the contents liquid from being deteriorated by the fragments 6.

When the distance L between the upper end 5a on the inner peripheral side of the score 5 and the contact portion 2d is set to be within 2 mm, the contact portion with the score 5 closest to the contact portion 2d is set. 2d
Therefore, the score 5 can be broken and opened with a relatively small pressing force due to the principle of leverage. In this case, the thickness of the synthetic resin layers 4a and 4c is set to 20
If the distance is set to 60 mm, the distant score 5e is protected by the synthetic resin layers 4a and 4c, and the fragments 6 can be prevented from falling into the content liquid. It should be noted that once the score 5 is broken, it is extremely difficult to restore it to its original state.
Tampering can be easily detected.

Further, since there is no need to provide a through-hole in the opening portion and attach a sealing material to this through-hole as in the prior art, the liquid container with a spout according to this embodiment can be easily manufactured. it can.

The above-mentioned aluminum alloy plate 4b of the aluminum laminated plate 4 has, for example, JIS 1100, 300
3, 3004 and 5052 can be used. The synthetic resin layers 4a and 4c are made of PE.
(Polyethylene), PET (polyethylene terephthalate) or PP (polypropylene).

Further, although there are no particular restrictions on the materials of the spout 1 and the push-in piece 2, the heat-sealing property of the injection-tube mounting surface 50b of the spout 1 is improved, and the spout 1 and the push-in piece 2 are opened after opening. In order to prevent the odor from being transferred to the content liquid, it is preferable that the odor is formed of a synthetic resin. In particular, pour tool 1
Is formed of a synthetic resin, it is possible to improve the bondability between the pipe mounting surface 50b and the synthetic resin layer 4a of the aluminum laminated plate 4.

Incidentally, as shown in FIG.
You may connect with the string 3 between and the injection cylinder 50a. Thereby, at the time of opening, the breakage progressed too much following the score 5,
Even when the fragments 6 shown in FIG. 3 are separated from the aluminum laminate 4, the fragments 6 can be prevented from falling into the content liquid.

Further, the score 5 can be formed on the synthetic resin layer 4c side. However, in this case, the synthetic resin layer 4c
It is preferable to process the score so as not to break. If the synthetic resin layer 4c is torn, the aluminum alloy plate 4b
Are exposed and the content liquid comes into contact with the aluminum alloy plate 4b, thereby deteriorating the content liquid.

Further, in the above-described embodiment, the shape of the score 5 is circular as shown in FIG. 6 (a).
As shown in (d) to (d), other shapes may be used. In particular, as shown in FIGS. 6C and 6D, the score is not an endless ring but has a tip 8a, and the contact point 8b of the contact portion 2d of the pushing piece 2 is substantially opposite to the tip 8a. If it exists on the side, since the progress of the break stops at the tip 8a, the possibility that the fragments 6 shown in FIG.
