DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper can package suitable for packaging processed food products for souvenirs.

[0002]

2. Description of the Related Art Conventionally, a small box made of polystyrene foam is generally used as a package for pickling souvenir products such as pickled Nozawana and kimchi, which is relatively heavy and contains watery and soft contents. The opening is closed with a Styrofoam box lid and tied up with a Styro rope.
A handle hanging from a rope is hung on the opposite side of the opening of the small box.

[0003] However, since such a styrofoam package is made of styrene, due to the inconvenience of waste treatment and the like and the concern of environmental pollution, a recyclable or perishable material has recently been adopted. That is especially shouted.

[0004] Metal materials such as aluminum and spoilable special biomaterials are costly. However, since they have relatively strong shape-retaining power as a package, they have recently been used in cup noodles and cup miso soup. The inventor paid attention to using a cylindrical paper can (paper cup) with a bottom. Actually, a paper layer of cup noodles or cup miso soup has a resin layer laminated on the inner surface of the cup because of the necessity of pouring hot water, so that water resistance and heat resistance can be ensured. However, in the case of a paper can-type package (container), which only stores and stores processed foodstuffs in plastic bags as contents, there is no need to laminate a special resin layer on the inner surface of the cup. Corresponds to forms that are rich in spoilage.

[0005]

A paper can package containing light contents, such as cup noodles, can be easily grasped with one hand even if it has a relatively large diameter, but is relatively heavy. Hold a heavy (high specific gravity) content (300 g or more) and have a relatively bulky (about 10 cm or more in diameter and 8 cm or more in height) paper can-shaped package, even an adult can pick it up with one hand Are difficult to lift or carry. In order to ensure this convenience, the paper can-shaped package may be tied up with a rope and attached to a hanging handle. However, unlike a rectangular parallelepiped box, a bottomed cylindrical paper can is hard to be tied up with a rope, and the tied rope is easily biased while being carried, so that the carrying durability is poor.

In view of the above problems, an object of the present invention is to provide a paper can-shaped package having relatively heavy contents and a relatively bulky size, which can be easily lifted or carried, and can be carried easily. An object of the present invention is to provide an excellent paper can-shaped package.

[0007]

Means for Solving the Problems To solve the above-mentioned problems, a means taken by the present invention is to provide a suspending cord in the center hole of a paper-made disc-shaped cover for closing the opening of a bottomed cylindrical paper can. Through
The disk-shaped cover and the bottomed cylindrical paper can are wrapped in a heat-shrinkable resin film wrapping material. That is, the present invention
In a paper can-shaped package having a bottomed cylindrical paper can for storing the contents and a paper disc-shaped cover for closing the opening of the bottomed cylindrical paper can, the disc-shaped cover is It has a flexible hanging string that has a retaining member on its back side and penetrates the center hole, along the circumference of the lower end of the bottomed cylindrical paper can and the circumference of the disc-shaped cover. A heat-shrinkable resin film wrapped around the circumference of the bottomed cylindrical paper can by bending and forming the inner peripheral flange-shaped overhang belts at the lower end and the upper end projecting to the center of the lower end surface and the upper end surface. It is characterized by having a material.

[0008] In such a configuration, by lifting the suspension string, the paper can-shaped package can be lifted without any problem. Here, the string refers to a flexible linear material including a rope and the like. When the hanging string is lifted, the bottomed cylindrical paper can is lifted up at the circumference of the disc-shaped covering lid via the upper inner peripheral flange-shaped overhanging band of the heat-shrinkable resin film wrapping material, Since the load is dispersed around the inner peripheral flange-shaped overhanging band, even a heavy content can lift the bottomed cylindrical paper can (content) without breaking the film. Even a bulky content with a bottomed cylindrical paper can having a large diameter or height can be easily lifted with a hanging string. Since the hanging string passes through the center hole of the disc-shaped cover, the bottomed cylindrical paper can can always be lifted in a balanced posture, so that even contents that are easily collapsed can be carried easily without collapse.

If the paper disc-shaped cover is thin and weak,
It is easy to bend when suspended, and there is a possibility that the circumferential edge of the disc-shaped cover may come off at the upper-end inner peripheral flange-shaped overhang band. In order to avoid this, a thick disc-shaped cover may be used, or the circumferential edge of the disc-shaped cover and the opening edge of the paper can-shaped package may be bound with a stapler binding needle. If the disc-shaped cover is made of a thick rigid plate, it is inconvenient to increase the cost and it is difficult to break the cover when cleaning it. When binding with a staple, it is difficult to open the disc-shaped cover at the time of opening, and since the staple is a metal needle, a feeling of strangeness remains particularly when the contents are food. Although it may be fixed with an adhesive tape or a double-sided adhesive tape, the number of steps of the bonding operation increases.

Therefore, a mode is adopted in which a reinforcing plate through which a hanging string penetrates is interposed between the disc-shaped cover and the retaining member. When the suspension string is suspended, the reinforcing plate overlaps and contacts the back surface of the disc-shaped cover by the retaining member, so the bending rigidity increases, the amount of deflection of the disc-shaped cover decreases, and the upper end inner peripheral flange-shaped extension band Of the disk-shaped cover can be effectively prevented from coming off. As such a reinforcing plate, a paper disk smaller in diameter than the disk-shaped cover can be adopted. In addition, when the disc-shaped cover is passed through with a string, it is only necessary to pass the reinforcing plate together, so that the number of working steps does not increase.

Further, in the structure in which the reinforcing material is wrapped around the hole edge of the center hole, breakage and expansion of the hole edge due to contact with the hanging string can be suppressed, and the hanging can be carried in a balanced posture forever.

Normally, the bottomed cylindrical paper can has a hill, but if the length of the hanging string is substantially equal to the radius of the hill, it is placed separately on the paper can-shaped package. By simply placing the paper can-shaped package, the hanging string can be stably stacked without being caught. At the time of display and storage of goods, the hanging string does not become an obstacle, and the loading operation can be speeded up.

The retaining member is preferably a knot of the hanging string itself. It is not necessary to use a separate part, and cost reduction can be realized.

However, when the contents having a considerable weight are stored, the entire load is applied to the peripheral edge of the disc-shaped cover, and there is a concern that the peripheral edge may come off.
In order to solve such a problem, the present invention employs a configuration in which the content itself is tied at the lower end of the hanging string, and the upper side of the hanging string is passed through the center hole of the disc-shaped cover. The entire load is applied directly to the suspension string itself and not to the disc-shaped cover. In addition, since the load of the contents is not applied to the bottom plate of the bottomed cylindrical paper can at the time of suspension, the bottomed cylindrical paper can can be prevented from being out of shape. As a result, the content hung by the hanging string is concealed by being covered by the bottomed cylindrical paper can and the disc-shaped cover. Therefore, regardless of the weight of the contents, hanging and carrying can be performed.

[0015] When the hanging string is a ring-shaped hanging string, a finger can be inserted and hooked, and the hanging string can be carried, so that a form excellent in lifting or carrying convenience can be realized.

The paper can-shaped package 10 of this embodiment has a closed cylindrical paper can 2 for storing contents 1 such as pickled Nozawana pickled in a plastic bag, and an opening 2 a of the closed cylindrical paper can 2. And a cardboard disc-shaped cover 3 to cover. Bottomed cylindrical paper can 2
Is a hill 2c protruding below the bottom plate 2b, and a circumferential edge of the opening 2a is a rounded edge 2d. The disc-shaped cover 3 has a center hole 3a, and a flexible hanging string 4 penetrates the center hole 3a.
The hanging string 4 is a ring-shaped hanging string, and the disc-shaped cover 3
A knot ball 4a as a retaining member is formed on the back surface side of. The circumferential side surface of the bottomed cylindrical paper can 2 is covered with a heat-shrinkable resin film wrapping material 5. At the lower end of the heat-shrinkable resin film wrapping material 5, the lower end inner peripheral flange-like overhanging band 5a that extends around the lower end circumference of the bottomed cylindrical paper can 2 and that projects toward the center of the lower end surface is bent. Is formed. At the upper end of the heat-shrinkable resin film wrapping material 5,
Along the circumference of the disc-shaped cover 3, an upper-end inner peripheral flange-like overhanging band 5 b projecting toward the center of the upper end surface is bent. Then, the heat-shrinkable resin film covering material 5
A peeling perforation 5c is formed in the vicinity of the rounded edge 2d of the bottomed cylindrical paper can 2.

By gripping and suspending the hanging string 4, the paper can-shaped package 10 can be lifted without any problem. When the hanging string 4 is lifted, the bottomed cylindrical paper can 2 is lifted up at the circumferential edge of the disc-shaped covering lid 3 via the upper inner peripheral flange-shaped overhanging band 5b of the heat-shrinkable resin film wrapping material 5. Since the load is distributed around the inner peripheral flange-shaped overhang band 5b, even the heavy contents 1 can be lifted without breaking the film.

Even if the bulky content 1 is large in diameter and height of the bottomed cylindrical paper can 2, it can be easily lifted by the hanging string 4. Since the hanging string 4 passes through the center hole 3a of the disc-shaped cover 3, the bottomed cylindrical paper can 10 can always be lifted in a balanced posture, and the contents 1 that are easily broken can be carried without being easily broken. Since the hanging string 4 is a ring-shaped hanging string, the hanging string can be carried with the finger inserted and hooked.

Although the bottomed cylindrical paper can 2 has a platform 2c, as shown in FIG. 5, in this embodiment, the length L of the hanging string 4 withdrawing upward is substantially equal to the radius R of the platform 2c. There is. If the upper exit length L is longer than the radius R, when another paper can-shaped package 10 is placed on the paper can-shaped package 10,
The hanging string 4 is easily pinched under the hill 2c, and it is difficult to stack the strings in a stable posture. However, if the length is not too long, the hanging string 4 can be stacked without tilting without placing the hanging string 4 simply by placing another paper can-shaped package 10 on the paper can-shaped package 10. At the time of display and storage of goods, the hanging string 4 does not become an obstacle, and the loading operation can be speeded up. In addition, if it is too short, it becomes difficult to suspend the suspension.

[Embodiment 2] FIG. 6 is a partially longitudinal front view showing the front of a paper can-shaped package of Embodiment 2.

The difference between the paper can-shaped package 20 of the present embodiment and the paper can-shaped package 10 according to the first embodiment is that a ball through which the hanging string 4 penetrates between the disc-shaped cover 3 and the knot ball 4a. A paper-made reinforcing disk 6 is sandwiched therebetween, and a reinforcing seal 7 is stuck to the back hole edge of the central hole 3a of the disk-shaped cover 3.

When the suspension string 4 is suspended, the reinforcing disc 6 is overlapped with and contacts the back surface of the disc-shaped cover 3 by the knot 4a of the retaining member, so that the bending rigidity is increased and the amount of deflection of the disc-shaped cover 3 is small. Thus, it is possible to effectively prevent the circumferential edge of the disc-shaped cover 3 from coming off at the upper end inner peripheral flange-shaped overhang band 5b. Therefore, even heavy contents can be hung. When the disc-shaped cover 3 is passed by the string 4, it is only necessary to pass the reinforcing disc 6 together, so that the number of working steps does not increase.

A reinforcing seal 7 is provided at the edge of the center hole 3a.
In this structure, breakage of the hole edge due to contact with the hanging string 4 and its expansion can be suppressed, and the hanging and carrying can be performed forever in a balanced posture.

[Embodiment 3] FIG. 7 is a partially longitudinal front view showing the front of a paper can-shaped package according to a third embodiment.

In the paper can-shaped package 30 of the present embodiment, the contents 1 themselves are bound at the lower end of the hanging string 4. The knot 4a of the hanging string 4 is placed and the upper side is passed through the center hole a of the disc-shaped cover 3. In such a configuration, the entire load is directly applied to the suspension string 4 itself, and is not applied to the disc-shaped cover 3. In addition, since the load of the contents 1 is not applied to the bottom plate 2b of the bottomed cylindrical paper can 2 at the time of suspension, the bottomed cylindrical paper can 2 can be prevented from being out of shape. Therefore, regardless of the weight of the contents 1, hanging and carrying becomes possible. The contents 1 may be placed on a receiving plate, and the receiving plate may be hung by the hanging string 4. Contents 1
May be hung using a hook or the like instead of being bound by the hanging string 4.
