JP6106966B2 - Easy-to-use bag-in-box - Google Patents

Description

  The present invention relates to an outer box of a bag-in-box in which an inner bag with a spout filled with a liquid is contained in the outer box, and in particular, an opening is provided in the top panel of the outer box. The present invention relates to a bag-in-box that can be easily charged with a coolant.

  Conventionally, plastic containers (bottles) such as polypropylene resin (PP), polyethylene terephthalate resin (PET), or polyvinyl chloride resin (PVC) have been widely used as containers for storing various beverages, seasonings or liquid detergents. It was.

  However, the increase in waste in recent years has become a major social problem, and as a result, it has become a global environmental problem along with the problem of resource protection, energy saving and resource saving. It has come to be desired.

  In view of the above problems, environmentally-friendly liquid containers, particularly as a business-use liquid container having a large internal capacity (about 2 to 30 liters), a cardboard outer box and soy sauce inside Combining containers (hereinafter referred to as bag-in-box) containing plastic film-filled bags with spouts that are filled with liquids, such as soy sauce, edible oil, liquor and other foods and detergents, development It has become widespread as a business liquid container for storing liquids and the like.

  However, in the case of the conventional bag-in-box, when it is necessary to adjust the temperature of the contents in a relatively short time, it is difficult to easily perform the contents with the contents in the interior bag. One example is the cold preservation of wine. Bag-in-boxes that store wine are often used outdoors.

  For example, when drinking outdoors such as in a barbecue or camping, there are many cases where the refrigerator or other cooling device is not fully equipped. For this reason, the wine itself is subdivided into other small-capacity bottles in advance. Although it is conceivable to put it in a large container containing it and deliver it from a bottle that has been subdivided just before drinking with a glass, etc., this method is not only complicated, but it also causes a problem that the flavor deteriorates due to loss of air during transportation. I am confused.

  Therefore, it would be convenient if the contents could be easily cooled with a cooling agent without taking out the contents from the bag-in-box. However, a normal bag-in-box exterior box is made rugged to protect the contents at the time of transportation, so it is not possible to easily inject a cooling agent or the like from outside the box without breaking the box.

  In addition, when an ice-packed ice pack is inserted into the outer box, the shape of the cryogen is apt to collapse and it takes a large volume to make contact with the contents over a wide area. It is a problem that you have to put in the cooler.

  With respect to the latter problem, in Patent Document 1, there is little decrease in the effective internal volume due to the placement of the cryogen, and the outer box is used as a bag-in-box type transport container that can easily cool the inner bag from the side. There has been proposed a transport container in which a cryogen frozen by absorbing water in a sheet containing a water-absorbing plastic is disposed in a gap between interior bags.

  According to this method, it is possible to effectively cool the contents with a small volume of the cold-retaining agent. However, the cold-reserving agent itself is charged before the outer box is sealed or before the contents are used. Therefore, it is difficult to simply put the cooling agent at a relatively short time before use.

  When the cooling agent is charged before the outer box is sealed, it is often difficult to use the contents during the period in which the effect of the cooling agent is continued. Further, if the outer box is opened at a predetermined time before the contents are used, the outer box is destroyed, so that it is difficult to hold and carry the contents thereafter.

  Patent Document 2 is superior in terms of cost and resource saving, and can stably carry even a 5 to 10 L beverage, and can smoothly and completely pour out the content liquid from the packaging container. As a bag-in-carton made using cardboard sheets made of inexpensive waste paper and also capable of cosmetic printing, an exterior carton formed from cardboard sheets and an interior with a spout arranged in the exterior carton In a bag in carton comprising a bag, an easy to carry bag in carton is proposed, characterized in that the top panel of the outer carton has two openings and a band-shaped handle between these openings. ing.

  Here, two openings are opened in the top panel to form a strip-shaped handle, and it is not impossible to put a small cooling agent from here, but these openings can be operated with fingers at best. Since the strength of the handle or the top panel after punching the handle becomes unstable if the size is increased, it is difficult to add a coolant having a certain size or more from here.

  From the above circumstances, there has been a demand for a bag-in-box having a simple structure in which a cooling agent can be easily introduced from the outer box before or during use of the contents.

Japanese Patent Laid-Open No. 3-256865 JP 2003-128138 A

  As shown in FIGS. 1 to 3, the outer box (100) of the bag-in-box according to claim 1 of the present invention has a bottom panel (1) and a pair of side panels (2) connected to both ends thereof. ), (3), the top panel (4) connected to the side panel (2), and the bonding part (5) provided on the top panel (4) are bonded together to form the body part. A bag-in-box comprising an outer packaging box (100) and a spout-equipped inner bag (30) arranged in the trunk, the bonded top panel (4) having a substantially central portion An opening region (16) surrounded by a ruled line (16a) and a cut or perforation (16b) is provided in at least a part of the width including a part of the flap, and a cut or perforation is formed at the end of the opening region. And a finger hole (18) surrounded by An in-box.

As the material of the outer box used for the bag-in-box of the present invention, a cardboard sheet is usually used, but paper may be used for a small capacity.
FIG. 3 shows only the inner bag (30), the outer box (100), and the spout (31) constituting the bag-in-box.

The interior bag (30) includes a film type and a molded type. Although many are mainly made of polyethylene, it is possible to use a multilayer composite film in order to improve the barrier performance.
An example of a composite film is LLDPE / EVOH / LLDPE. The inner bag may be a double bag in consideration of the occurrence of pinholes.
A spout (31) provided with a screw lid in advance is formed at one end of the synthetic resin interior bag.

Next, an example of a specific form of the outer box (100) used in the bag-in-box of the present invention will be described.
As shown in FIG. 1, a blank forming an exterior box used in the bag-in-box of the present invention is formed by punching a corrugated cardboard sheet and bending each panel by a ruled line.
Note that cosmetic printing is performed on the surface of such a blank by direct printing, preprint printing, or the like.

In the blank of FIG. 1, a pair of side panels (2) and (3) are connected to both ends of the bottom panel (1) via ruled lines. Further, the top panel (4) is foldably connected to one end of the side panels (2) and (3). Furthermore, the pasting part (5) is continuously provided on the extension of the top panel 4 via a ruled line.
Further, folding flaps (7), (7a), (8), (8a) are connected to both ends of the bottom panel (1) and the top panel (4), respectively, and the side panels (2), (3 The lid flaps (9), (9a), (10), and (10a) are connected to both ends of the bracket.
The lid flaps (9), (9a), (10), (10a) are overlapped on the folding flaps (7), (7a), (8), (8a), and both end faces of the cylindrical body part Is closed and sealed.
The lid flap (9) and the folding flap (7) are provided with a cutout (32) for projecting the spout (31) of the inner bag (30) from the outer box.

Next, the structure of the opening part area | region provided in the top | upper part of an exterior box (100) is demonstrated.
In this embodiment of the present invention, the opening region for supplying the cooling agent is formed by a ruled line (16a) for folding along the longitudinal direction of the top panel (4) and a notch or perforation (16b) connecting both ends thereof. It is formed between the ruled line (16a), the top panel (4), and the ridgeline of the side panel (2).

The position and shape of the opening region provided in the top of the outer box (100) is not particularly limited as the opening for charging the cooling agent, but the content can be effectively reduced by reducing interference with the content. In order to cool the battery, it is usually set so that the cold insulating agent is introduced from a position near the end of the top panel. FIG. 2 (B) shows the state when the cooling agent is added.
Further, the folding ruled line (16a) may be cut or perforated considering only the introduction of the cooling agent, but it needs to be a ruled line that can be easily held and resealed in consideration of subsequent handling and storage.

By doing the above, it becomes possible to open to a predetermined area of the top panel, but if there is no part that triggers the opening, it may be difficult to open a hole in a sturdy outer box with bare hands is there.
For this purpose, the outer box used in the bag-in-box of the present invention has a finger hole (18) surrounded by notches or perforations that can be easily opened by pushing with a finger at the end of the opening area of the top panel.

  Furthermore, in the exterior box (101) used for the bag-in-box according to claim 2 of the present invention, as shown in FIG. 4, an opening region (16a) surrounded by a ruled line (16a) and a cut or perforation (16b) ( 16) A ruled line (17a) and a notch (17b) for forming a hole (17) to be a handle are provided inside.

Therefore, if it is necessary to carry the bag-in-box by hand after putting in the coolant, push this notch (17b) and fold it along the ruled line (17a) to open the hole (17) where the finger of the hand enters and open it. In addition to being able to handle and handle, it can also be used when pouring from a bag-in-box into individual containers such as cups and glasses. FIG. 4B shows a state in which the opening region (16) is erected and a cooling agent is put into the exterior box (101).

  Further, the folding ruled line (17a) may be cut or perforated if it is only grasped with a finger and carried around, but considering the subsequent handling and storage, it is the same as the folding ruled line (16a). The ruled line must be easy to hold and resealable.

In addition, the exterior box (102) used for the bag-in-box according to claim 3 of the present invention has an opening region (16a) surrounded by a ruled line (16a) and a cut or perforation (16b) (see FIG. 5). 16) and an opening area (16 ') surrounded by a ruled line (16a') and a notch or perforation (16b ') at symmetrical positions on the top panel (4), and inside each area Is provided with ruled lines (17a), (17a ') and cuts (17b), (17b') for forming holes (17), (17 ') to be handles, and cuts or sewing machines at the end of each region It is a bag-in-box that is easy to put in a cooling agent, and has finger holes (18) and (18 ') surrounded by eyes.
FIG. 5B shows a state in which the opening region (16) and the opening region (16 ′) are erected and the cooling agent is put on both sides of the inner bag (30) inside the outer box (102).

  Since the opening can be opened at two places, it becomes possible to cool more strongly by arranging the cold insulation agent from both sides of the interior bag in this way.

  In addition, since a pair of upright opening areas with holes to become handles can be formed on the upper surface of the outer box, it can be handled more stably by gripping and handling both after the introduction of the cryogen, and individual containers It is also convenient when you want to pour them over.

The bag-in-box in which the cooling agent can be easily charged according to the present invention can be easily assembled by an ordinary box making machine.
