Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The disclosed technology relates to a structure of a soft packaging container which fills and stores products such as snacks such as potato chips and other light and bulky foods, and packs as much as possible in a sealed state. Belongs to the technical field.

[0002]

2. Description of the Related Art As is well known, various products have been traded in a variety of forms in the secondary market with the improvement of citizens' lives. Even maintaining hygiene and quality,
While there has been a strong demand for improvements in processing efficiency and the like, similar strictness is also required in the handling of commodities in the distribution stage from production to sale.

[0003] By the way, in the distribution stage, it is difficult to handle the product as it is exposed due to the above sanitary condition,
From the viewpoint that it is not preferable from the viewpoint of maintaining quality and the like, a mode in which the container is packaged in a predetermined container and handled and processed is generally used.

[0004] Incidentally, in the packaging of products such as foods of snack confectionery such as the potato chips, the products themselves such as the snack confections such as the potato chips are generally light in weight and low in strength and rigidity. In the course of handling, or in the middle of shipping to stores, etc., the packing containers are filled with each other as densely as possible because they are easily damaged. It is also necessary to fill the air together, so in order to maintain the shape retention of the filled state, a so-called soft packaging mode is generally used.For example, when manufacturing a container using a sheet made of a laminate film or the like as a material, In addition, a mode of automatically filling the product is adopted.

[0005] By the way, such a flexible packaging container has a shape and structure as shown in FIG. 16, and a pillow type 1 of (A) is used as a three-dimensional container for filling and packaging a predetermined amount of commodities.
And the gusset type 2 of (b) and the standing pouch type 3 of (c). The pillow-type flexible packaging container 1 of (a) in view of ease of production and convenience in handling. The gusset (b) is used because it has many advantages, such as good seating, good appearance and design, luxury feeling for the user, and easy arrangement on display shelves in stores. Flexible packaging containers 2 of the type are also quite widely used and have the advantages of both (c).
The standing pouch type flexible packaging container 3 is also used quite a lot depending on the types of products handled.

The pillow type 1 of the soft packaging container (a) and the gusset type 2 of (b) shown in FIG.
Also, in each of the embodiments of the standing pouch type 3 of (c), there is a certain space volume, and a considerable dead space is required between the boxes when packing cardboard boxes or cases. In the case of products that are hard to break in size or hard to break, for example, snacks such as peanuts and rice crackers, the so-called three-side seal packaging container 4 shown in FIG. 6D and the four-side seal soft packaging shown in FIG. Container 5
Is used, the content is relatively small, but the surface area is widened so that the volume can be seen large, use good packaging materials, give a sense of luxury, do not look expensive
It is used in such a form that it can be easily packed in a box such as a cardboard box or a case at a later stage.

[0007]

However, in the case of such a soft packaging mode, as described above, a predetermined amount of air may be optionally filled in a cushion-like manner in order to avoid damage to goods during transportation. Flexible packaging container (a),
In (b), (c), etc., when packing boxes such as cardboard boxes and cases, extra voids are made as close as possible to zero, but a considerable volume of dead space is generated between them. The bulk capacity is remarkably large in proportion to the weight, and there is a disadvantage that the transportation cost, the efficiency of packing the case and the packing of the corrugated cardboard are poor.

[0008] In addition, in the present day when pollution problems and environmental harmony problems are highlighted on a global scale, the material of packaging containers is reduced as much as possible, the volume of waste is reduced, and the handling efficiency is improved. In addition, it is necessary to add cost reduction, resource saving, and the like, and even in the distribution stage, there is a strong demand for improvement of the filling efficiency from this viewpoint.

In order to perform flexible packaging, printed sheets of advertisements or sheets made of a laminated film or the like are used in terms of airtightness, etc., but in terms of maintaining the shape of the flexible packaging container as a product. The stronger the rigidity (so-called waist) of the film sheet, the better the shape retention performance, and it is possible to use a case such as an automatic caser to efficiently perform work such as packing into a case or a cardboard box in an integrated state. However, the poor filling efficiency when the case or the cardboard is filled with the auto caser or the like is due to the above-mentioned conventional soft packaging containers (a), (b), and (c). Is unavoidable, and there is a bottleneck that cannot be addressed despite the increasing demands for immediate resolution due to recent environmental harmonization issues.

However, when the three-dimensional soft packaging containers (a), (b), and (c) are used as soft packaging containers (d) and (e) which are almost flat, filling and packaging of snack confectionery such as potato chips is not possible. There is a limitation that there is a limit, and the product is easily damaged during handling.

Therefore, in each of the conventional soft packaging containers, it is essential that low-strength, rigid, and light-weight products such as potato chips and other snacks are filled with sufficient shape retention. Although it is possible, it is easy to handle, work efficiency is increased, cost can be reduced,
There was a downside that it could not fully meet the demand for the emergence of environmentally friendly flexible packaging containers.

In the embodiment (b) of the gusset type flexible packaging container 2, since the upper lid is a two-flow type, the near side of the upper lid has a corrugated cardboard case or a box for the case. There is a problem that a considerable dead space is unavoidably generated even when the packing is performed.

To cope with this, for example, Japanese Utility Model Publication No. 50-1
As disclosed in the invention of Japanese Patent Publication No. 0291, there can be considered a mode in which the lid is formed with a flat bottom on both the top and bottom. However, not only folding at the time of manufacturing the container but also the work of the sealing portion is extremely difficult. For example, there is also a mode using an inner bag or a hot melt in a container for filling and packaging coffee beans, but there is a difficulty that it is difficult to handle in the case of manufacturing with a sheet or the like using a laminated film as a material, snack confectionery etc. In the case of wrapping, there is a bottleneck that increases the cost.

In such a container form, it is necessary to pack a highly airtight product in a container and pack it in a carton (paper container), which can be used only for high-end products. is there.

[0015]

The purpose of the invention of the present application is to reduce the strength and rigidity based on the above-mentioned prior art, to be easily damaged, etc., to require sufficient care in handling, and to meet the demand for good filling efficiency. It is better to use a special packaging machine as a technical issue to solve the problem of flexible packaging containers for products,
Since the equipment cost will be high, make use of the function of the current pillow type packaging machine manufacturing equipment as much as possible, add only the missing parts,
The function can be fulfilled, and it can be packed in a case or cardboard box with good filling efficiency, it has good appearance, it is easy to handle, and it has a good sitting position at the end of the store and is effective It is an object of the present invention to provide an excellent flexible packaging structure which can perform the above operations and improve the display effect of the advertisement text, thereby improving the application field of product handling technology in the distribution industry.

[0016]

Means for Solving the Problems According to the above-mentioned object, the constitution of the invention of the present application, which is based on the claims of the above-mentioned utility model registration, is designed to solve the above-mentioned problems by providing various kinds of snacks such as snacks, etc. For soft packaging of low-damage and easily breakable products, it is used in a bag-filling and filling device for pillow-type packaging containers and the like in the conventional mode through a single sheet valley line or mountain fold line such as a laminate film. A suitable attachment is added and bent in a foldable manner to form a rectangular cross section and the lower lid is formed in a flat bottom, and the upper lid is formed into a single-flow type after filling the product in a predetermined manner after the flat bottom is formed. When the soft-packaged containers are arranged in a one-to-one facing position, the single-flow type upper lids come into close contact with each other so that the containers complement each other in a rectangular parallelepiped shape or the like. Both the flat bottom and the top lid are sealed and sealed, and when packed into a case or cardboard, the tops of the soft packaging containers are in close contact with each other, and the containers complement each other in an orderly manner via an auto caser. In this way, the filling efficiency of the case or cardboard is significantly improved, and the product itself is prevented from being damaged through a cushioning action by a predetermined amount of air that is additionally filled without causing rattling of the product in the handling and transport process. It is also easy to take out at the delivery destination, etc.
The arrangement on the display shelf of the store is also comfortable, and the letters and patterns of advertisements and explanations displayed on the surface of the store have a large area so that they can be seen easily, so that the value of the product does not decline and the cost is reduced. It is cheaper, saves resources, uses as little waste as possible, has no pollution, and takes technical measures to ensure good environmental harmony.

You.

As shown in FIG. 6, in the case of a sheet made of a laminated film made of a material, the upper cover 9 'is provided with a sheet as shown in FIGS.
As shown in FIGS. 3 and 11, a smooth plane can be formed.

The flexible packaging container 6 has a flat inclination angle of, for example, 45.degree. In the plane of the upper lid 9 ', and the sealing portion 12' has a flat surface along the shape parallel to the rear surface 8 '. As shown in FIG. 9, when the pair of flexible packaging containers 6 and 6 are packed in their respective upper lids 9 'and 9', as shown in FIG.
9 and 10, the upper lids 9 ', 9' complement each other to form a rectangular cross section, and the end faces are more integrated with the lower lids 9, 9, as shown in FIGS. It can be made into a rectangular parallelepiped block, so that both flexible packaging containers 6,6
No dead space or the like is formed at the end in the opposite arrangement posture.

For this reason, as shown in FIG. 10, for example, when filling a rectangular case or corrugated cardboard 16 with a filling box through an auto caser or the like, the soft packaging containers 6 complement each other and almost dead space. It can be packed in a box with high filling efficiency, and filling and unloading through an auto caser can also be performed very efficiently and quickly with high efficiency.

Incidentally, reference numeral 11 denotes a back stick, and 13 denotes a cut notch.

[0029] In the above configuration, because conceived of this application relates to a soft capsule <br/> instrumentation container structure is omitted detailed disclosure description of the manufacturing process or the process is made a predetermined laminated film material One sheet is folded in a process as shown in FIGS. 4 to 8 through a mountain fold line 10 and a valley fold line 10 'which are formed in advance, including so-called bent seal forming (hem forming), and potato chips. A predetermined amount of snack confectionery such as is charged and filled by a set amount at the same time. At this time, a predetermined amount of cushion air is also enclosed, and the folded state of the upper lid 9 ′, the folded portion 14, 14 ′, and the sealing portion 12 ′ are sealed by heat sealing. The flexible packaging container 6 shown in FIG.

Thus, since the automatic filling and packaging is performed by the automatic bag making apparatus, the front surface 8, the rear surface 8 ', and
The bottom cover 9 and the top cover 9 'are formed of almost smooth planes except for the sealing portions 12', 12 '(partially valley broken lines 10' and the like on the side surface 9 '' form slightly unevenness). ,
Also, depending on the design, there is a mode in which the backing 11 is formed on the front surface 8, the rear surface 8 ', the bottom cover 9, and the top cover 9'), but the smoothest possible plane is as shown in FIG. , Top lid 9 ′ or front 8 ′
Even if patterns 15, 15 'such as advertising texts and picture patterns are displayed, if a packaging material having a "waist" according to the contents is selected and used, wrinkles and distortions are extremely small and are displayed visually. The area can be large so that it does not detract from the appearance.

Then, the soft wrapping containers 6, 6... In which air as a cushion is enclosed in the snack confectionery as these products are packed in a case or a corrugated cardboard 16 in a predetermined amount as much as possible. 9 can be used more easily than the pillow-type flexible packaging container 1 even when packed in a box with a good filling efficiency, even if it is manually packed or packed into a case using an auto caser to save labor. , As shown in FIG.
Can be filled with a higher filling efficiency than the pillow-type packaging container 1 shown in FIG. Needless to say, compared to the gusset type flexible packaging container 2 shown in FIG. 16B or the standing pouch type flexible packaging container 3 shown in FIG. Can be transported and handled in a predetermined number of flexible packaging containers 6, 6, ... without any backlash during transportation in the distribution process, so that snacks such as potato chips as commodities can be produced. Even if it is bulky, it can be transported and handled without deteriorating the value of the product, and it can be taken out and displayed even at the destination store. In addition, even in the vertical type display mode shown in FIG. 11, not only can the gusset type flexible packaging container 2 and the like be displayed comfortably, but also the advertisement and the pattern 15 on the top lid 9 'can be displayed. , 15 ′, etc., have a large display area and are most visible to the consumer, and when viewing the front surface 8, the slope of the upper lid 9 ′ is also fully visible, as well as the appeal effect is large. Because of the single-flow type, a wider slope area than the upper lid of the gusset type packaging container 2 can exhibit a large advertising effect.

Then, in the upper lid 9 ', the sealing portion 1
Heat sealing to the folded portion 14 at the upper part of the 2 'and the side surface 9'', or double or quadruple overlapping sealing by hot melt etc.
The rigidity can be maintained sufficiently.

As described above, the higher the film hardness (so-called stiffness) is, the better the function of maintaining the shape of the flexible packaging container 6 is, as described above. Due to the heat-sealing of the triple-folded portion, sufficient strength and rigidity are exhibited, and the shape retention of the soft packaging container 6 is sufficiently obtained. Sufficient shape retention can be exhibited even against vibration and the like.

As shown in FIG. 11, a cut notch 13 is slightly formed at the end of the sealing portion 12 'of the upper lid 9' so that a lateral orientation is revealed by heat sealing. By doing so, opening at the time of use is performed extremely smoothly as in the conventional mode.

Further, since the inside of the soft packaging container 6 is completely sealed, there is no invasion of germs or the like from the outside, the sanitary condition is sufficiently ensured, and there is no generation of acid rot.

In addition, there is no deterioration due to invasion of moisture, quality assurance is maintained, and a reduction in commercial value is completely prevented.

As shown in FIG. 11, the arrangement of the display shelves in the store is different from that of the gusset type flexible packaging container 2, and the orientation of the arrangement is uniquely determined. The packaging containers 6, 6,... Are arranged in a random manner, the volume is emphasized, the appearance is well aligned, and the work efficiency can be improved.

By the way, the flexible packaging container of the present invention has good packing and taking-out properties in a case or a corrugated cardboard through an auto caser or the like. The upper lids 9 ′ and 9 ′ are complementary to each other, that is, the pair of flexible packaging containers 6 and 6 are arranged adjacent to each other with the front and rear directions reversed. Since the technical concept is based on the fact that the filling efficiency is good, if the development that can be manufactured technically is performed, the upper lid 9 'will be described with reference to FIG.
2 to 15 can be designed in various forms of opposed and complementary top lids 9 ", 9"".

Needless to say, there is a wide range of choices and adoption from the viewpoint of the difficulty of the manufacturing process or the cost.

The flexible sheet as the material is not limited to the one made of a laminate film, and is not limited to only one sheet. Other sheets made of paper or cloth, and furthermore, a net-like sheet may be used. Obviously you get it.

And, as a matter of course, the merchandise to be filled has the above-mentioned merits even if potato chips or the like are other than snacks.

[0042]

As described above, according to the invention of this application, basically, a snack confectionery such as potato chips is filled with a predetermined amount of low-strength, low-rigidity, light-weight food products or the like, and a sealed bag-shaped bag is produced. In the soft packaging container, the cross section is square, and it is a soft packaging container that can be filled into a case or corrugated cardboard through an auto caser, etc. In display, etc., the seating is good, the box is easy to pack, the volume feeling is emphasized, and in the arrangement of the flexible packaging containers, the upper lids are mutually adjacent so that the upper lid opposite to the lower lid is adjacent to the lower lid. Since the products can be brought into close contact with each other so as to complement each other, even if the product to be filled in the flexible packaging container is filled with cushion air, peanuts, rice crackers, etc. If the product is hard to break, this soft packaging The use of the air conditioner reduces the amount of enclosed air and increases the filling rate in the packaging bag, and when packed in a case or cardboard box, the dead space is as small as possible, the filling efficiency is increased, the weight of the product is light and bulky. If the same quantity is used for transportation, it is extremely excellent that the volume is reduced so that rattling does not occur, there is no decrease in quality value, delivery efficiency is increased, and distribution costs can be reduced. The effect is achieved.

Further, since the mutual arrangement at the time of box packing or the like is closely and closely adjacent to each other, handling or
Even if rocking or vibration occurs during the transportation, the vibration generated during the transportation also has the effect of adjusting the filling form of the packaging container, and the behavior of the filled products is small, leading to damage and the like. There is also an effect that the product value is hardly reduced.

In addition, the upper lid has a novel appearance compared to conventional gusset-type or standing pouch flexible packaging containers such as a one-flow type, and is excellent in design, and displays advertisements and patterns displayed in a good design. Because the area is easy to see and wide, and the sense of volume is emphasized, there is also an appealing effect to consumers, and the display work can be organized at the time of display, which can increase the product value from this point. This has the effect of being able to do so.
