Description

  The present invention relates to an outer box for storing an inner bag for a bag-in-box, and a bag-in box in which an inner bag for a bag-in box is stored inside the outer box, and in particular, reduces unpoured liquid in the bag. The structure of the exterior box provided with the function is the main part.

  A flexible packaging bag filled with a beverage liquid such as wine and having a spout is used as a primary container (inner bag), and this primary container (inner bag) is stored to retain its outer shape. A product (for example, a flanger: 3L type) made of a container (also referred to as a “bag-in-box”) having an exterior box provided for this purpose already exists on the market.

  Such products are cheaper than candy products, can be stored neatly in a refrigerator as a box, and are easy to pour because there is a spout. By combining with the inner bag functionality, there is an excellent merit that the freshness after opening can be maintained over a long period of time.

An example of such a conventional product (bag in box) is shown in FIG. 8 and FIG.
FIG. 8 is a perspective view showing a schematic form (exterior box form) as it is distributed in the market, and FIG. 9 is a perspective view showing a schematic form in which a spout 290 is attached to the external box 200. is there.

  An example of a procedure for attaching the spout 290 to the outer box 200 will be briefly described below. First, the entire perforation 210a having a circular shape indicated by reference numeral 210 in FIG. 8 is strongly pressed with a finger to form a cut cavity. Thereafter, the perforation 220a having the form of the reference numeral 220 is cut out with the hollow portion as the base point, and the opening flap piece of the reference numeral 220 is turned forward with the folding line 221 as the base line. Next, the spout 290 attached to the bag housed in the outer box 200 is pulled out of the outer box with its root, and is fitted into the portion of the reference numeral 210 cut out in a circle. Thereafter, the opening flap piece denoted by reference numeral 220 is returned to its original position, and the spout 290 is sandwiched from above and below and completely fixed (state of FIG. 9). After fixing the spout 290, by preparing a glass or the like under the spout 290 and turning the turning plug (knob) 291, the liquid content can be poured out from the lower portion 295 of the spout 290. .

  Such a series of operations is described in detail in the outer packaging box of a product as a procedure of a method for opening a product already on the market.

  However, it has been confirmed that when a product having such a structure is used as it is without any ingenuity, a considerable amount of unpoured residue (about 23% of the internal volume) can be generated. For this reason, research reports have been obtained that the user is working to pour out the remaining portion by a unique method such as tilting the box body toward the spout side by holding the box body. In addition, it is known from survey reports that there are overwhelmingly many forms that are poured out from the inside of ordinary refrigerators.

  The exterior box of the present invention is an exterior box for storing a bag-in-box inner bag having a spout, and an example of a specific embodiment of the exterior box will be described below with reference to the drawings.

  FIG. 1 shows an example of a developed view of an exterior box 1 of the present invention, and FIG. 2 is a schematic perspective view of the assembled original cardboard of FIG. 1 assembled as an exterior box.

  The form of the exterior box 1 of the present invention can be understood from the development shown in FIG. 1 and the schematic assembly completion diagram of FIG.

  As shown in FIG. 1, the exterior box 1 of the present invention forms a front plate 11, a rear plate 15, and a belt-like body portion formed with side plates 21 and 25 that connect them, and an upper lid. A pair of upper flaps 31 and 35 and upper lid outer flaps 41 and 45, respectively, and a pair of bottom flap inner flaps 32 and 36 and bottom lid outer flaps 42 and 46, respectively. It has.

  In the exterior box 1 of the present invention, as shown in FIG. 1, a cut-out corner (on the side of the front plate 11) on the front side of the pair of side plates 21, 25 and on the bottom lid side (see FIG. 1 and a sloped surface on the bottom lid side of the front plate 11 with a bent connecting piece 38 interposed between the front plate 11 and the bottom flap inner flap 32 on the bottom lid side. 38 (the bent connecting piece 38 forms an inclined surface).

  The presence of the inclined surface 38 makes it extremely easy to incline the entire box toward the front side (front plate 11 side) (see FIG. 2).

  The glue margin piece 9 shown on the right side of FIG. 1 is for integrally fixing the belt-like body portion in a cylindrical shape, thereby forming the cylindrical body portion. In addition, the assembly procedure of the exterior box 1 is not particularly limited, and the following procedure is a preferable example, and by showing this, it is possible to easily understand the box form after the assembly is completed from the developed view. it can.

  After the cylindrical body is formed as described above, the upper lid and the lower lid are formed. That is, the pair of inner flaps 31 and 35 for the upper lid are folded inward from the crease lines 61 and 81 shown in FIG. Next, the upper lid is formed by folding the pair of outer flaps 41 and 45 for the upper lid inward from the crease lines 71 and 91 and partially bonding them.

  Further, the bottom cover inner flap 36 is folded inward from the crease line 82 shown in FIG. 1, and the bent connecting piece 38 (substantially rectangular shape) is folded inward from the crease line 62, and further from the crease line 63 to the bottom cover. The inner flap 32 is folded inside. Next, a pair of bottom lid outer flaps 42, 46 are folded inward from the crease lines 72, 92 and partially adhered to form a bottom lid.

  A schematic perspective view of the outer packaging box 1 after assembly is shown in FIG.

  Note that an inner bag for a bag-in-box having a spout is accommodated in the outer box 1, and the timing (timing) and the storage port for storing the inner bag may be appropriately selected.

  Moreover, a well-known various thing can be used for the inner bag for bag-in-boxes provided with a spout. Generally, the inner bag is composed of a flexible packaging bag that can be easily deformed, and the spout is formed of a rigid injection molded member or the like. The spout and the inner bag are joined by, for example, fusion.

  The main parts (1) to (3) of the exterior box 1 of the present invention will be described below.

(1) Forming an inclined surface for inclining the outer packaging box 1 to the lower outlet side in order to reduce the unpoured liquid in the bag. There is a feature point different from the configuration of the prior art in that an inclined surface for inclining toward the spout side below the face plate 11 is provided.

  That is, at the location where the bottom cover side of the front plate 11 and the bottom flap inner flap 32 are connected, the bent connecting piece 38 is interposed, and the inclined surface 38 (the bent connecting piece 38 is inclined) on the bottom cover side of the front plate 11. Forming the surface).

  Due to the presence of the inclined surface 38, an unprecedented effect that the operation of inclining the entire box toward the front side (front plate 11 side) becomes extremely easy (see FIG. 2).

  Furthermore, it is preferable that the exterior box 1 of the present invention is configured to have the following function for maintaining an inclined state.

  FIG. 3 shows a state in which the top and bottom of the outer box 1 are reversed so that the bottom cover of the outer box 1 faces upward. In this state, an operation for maintaining the inclined state is performed.

  As described above, the pair of bottom cover outer flaps 42 and 46 are sequentially folded to form the bottom cover. As shown in FIGS. 1 and 3, in the stacking order, the bottom cover outer flap 46 is formed such that the corner 46 'on the rear plate 15 side can be bent in a triangular shape, For this purpose, a fold line 93 is formed in the bottom lid outer flap 46 (FIG. 1). On the other hand, as shown in FIGS. 1 and 3, the bottom lid outer flap 42 located on the lower side in the stacking order is a bent triangular corner portion of the bottom lid outer flap 46 located on the upper side. It has a slit 42a for inserting the top portion 46a of 46 '(FIG. 1).

  In order to insert the apex portion 46a of the triangular corner portion 46 'bent from the fold line 93 into the slit 42a, as shown in FIG. 3 and FIG. It is necessary to bend the corner 46 'again at an appropriate position. In FIG. 3 and FIG. 4, a line 95 which is arbitrarily folded once is indicated by reference numeral 95. Since the box itself has cardboard specifications and is close to the triangular top 46a, the folding line 95 can be easily formed on the user side. Although not shown in the present embodiment, the folding line 95 may be formed in advance at the product specification stage. By inserting the top portion 46a into the slit 42a, the folding line 95 forms a convex body.

  3 and 4, an operation for maintaining the inclined state is performed, and when the operation is completed, the outer case 1 is turned upside down so as to return to the original state. Then, the bent line 95 of the convex body becomes a grounding line and acts to lift the rear part of the exterior box 1. Thereby, since the whole box maintains the form still inclined to the front side (front plate 11 side) in which the spout was provided, the function which reduces the pouring residue of the liquid in a bag can be exhibited. The folding line 95 is preferably configured so that the line 95 itself, which is a grounding line, is horizontal in the width direction when the entire box is tilted to the front side.

(2) Specifications for installing the spout at a lower position to reduce the remaining amount The exterior box 1 of the present invention has a bag-in-box inner portion at a position straddling both the front plate 11 and the bent connecting piece 38. A spout fixing member 100 is formed so as to have an opening 101 for projecting the spout of the bag (FIG. 1).

  As shown in FIG. 1, the spout fixing member 100 includes an opening 101 that has a perforation and is formed in a substantially circular shape so that the spout of the inner bag for a bag-in-box is projected. It has an opening flap piece 105 for securing a work space for connecting and extending upward and pulling the spout of the bag-in-box inner bag to the outside and fixing the spout after the pull-out. Yes. In such a spout fixing member 100, in the present invention, the position of the spout can be further lowered, and the opening 101 is located across both the front plate 11 and the bent connecting piece 38, That is, it is formed at a position where the fold line 62 is cut and divided.

  The procedure for attaching the spout to the outer box 1 is substantially the same as that described in the section of the prior art. A brief description will be given below.

  First, the entire perforation 101a having a circular shape indicated by reference numeral 101 in FIG. Thereafter, the perforation 105a in the form of the opening flap piece 105 is cut off, and the opening flap piece 105 is turned up toward the front with the folding line 105b as the base line. Thereby, the work space for pulling out the spout of the inner bag for bag-in-boxes is secured. Subsequently, the base of the spout 160 (see FIG. 5) of the inner bag stored in the outer box 1 is pulled out of the box. A circular fitting groove (not shown) is formed in the base portion of the spout 160, and this groove is fitted to a circular portion 101. Thereafter, the opening flap piece of reference numeral 105 that has been turned up is returned to its original position, and a substantially semicircular portion at the bottom of the opening flap piece 105 is fitted into a fitting groove at the base of the spout 160, and the spout 160 Is fixed by sandwiching from above and below. It is not necessary to fix the pinch completely, and it is possible to use a fixing method with some play. This is because the spout 160 can be directed further downward.

  In addition, the site | part to which the base part of the spout 160 is fixed, ie, the location which straddles both the front board 11 and the bending connection piece 38, is not a plane but a bending surface containing gentle corners. However, since the material is made of corrugated cardboard, the opening 101 for fixing can be easily deformed to some extent, so that it can be fixed to some extent.

  After fixing the spout 160, a glass or the like is prepared under the spout 160, and the content liquid can be injected by turning the rotary stopper (knob).

(3) Specification for reducing the remaining amount of the bag stored in the outer box 1 while pouring it to the upper part of the box The outer box 1 of the present invention has a front plate 11 and an upper lid connected to the front plate 11. A bag pull-out opening member 150 is formed so that an opening for pulling out the bag-in-box inner bag is formed at a location straddling both inner flaps 31 (FIGS. 1, 2, 5, and 5). 6).

  The bag drawer opening member 150 has an opening start portion 151 and an opening flap piece 155 that is connected to the portion 151 and extends upward to form a space for pulling out the bag-in-box inner bag itself. Configured.

  The opening flap piece 155 is provided at a location straddling both the front plate 11 and the upper lid inner flap 31 connected to the front plate 11 so that the bag-in-box inner bag is pulled upward as much as possible to leave the remaining in the bag. This is to reduce the amount.

  The opening start portion 151 is set mainly for the purpose of creating a base point of the opening by pressing with a finger. The opening flap piece 155 connected to the portion 151 is configured such that the perforation 155a forming the form is cut upward, and the opening flap piece 155 can be turned forward with the folding line 155b as a base line. This state is shown in FIG. By this operation, an opening for bag withdrawal is formed as shown in the figure, and the inner bag B for bag-in-box B is pulled out from the opening and lifted slightly upward so that it remains without being poured into the bag. The liquid can be quickly moved to the spout.

  Thereby, the remaining amount of liquid in the bag can be reduced.

  In order to provide such an opening for pulling out the inner bag for the bag-in-box, as shown in FIG. 1, the end on the front plate 11 side of the pair of outer flaps 41, 45 for the upper lid, Cutout portions 40 and 44 having substantially the same shape as the opening formed at the end portion of the upper lid inner flap 31 on the front plate 11 side are formed. Here, “substantially the same shape” can be regarded as visually the same shape, and specifically refers to those having a dimensional error range of ± 20%.

  By the way, as shown in FIG. 7, in the setting of the inclined surface of the exterior box 1 of the present invention, the width W1 of the bottom lid inner flap 32 connected to the bent connecting piece 38 is the entire width of the bent connecting piece 38. The engagement ribs 38a and 38a are formed in the width direction of the bent connecting piece 38 by being smaller than the width W2. As a result, when the outer box is assembled as shown in FIG. 7, after the band-shaped body is formed, when the bent connecting piece 38 and the bottom cover inner flap 32 are folded along the box shape, the locking ribs are The side plates 21 and 25 can be engaged with the thickness portion end surfaces 21h and 25h of the side plates 21 and 25 located at the cut-out corners (symbol H). With such a configuration, the substantial rigidity of the box itself is increased, the box is given a firm feeling, and foreign objects are difficult to enter. It can also lead to ease of automatic packaging.

  An inner bag for a bag-in-box having a spout is housed in the outer box of the present invention having specifications as shown in FIGS. 1 and 2, and a FRANZIA 3L (liter) type bag-in-box sample of the present invention Was made.

  As a comparative example sample, a bag-in-box inner bag having a spout is housed in a conventional outer packaging box as shown in FIGS. 8 and 9, and a FRANZIA 3L (liter) type bag-in-box comparison is made. Example samples were made. In both samples, the same bag as a commercially available inner bag for box-in-box was used.

  Using these samples, the amount of pouring (mL) and the pouring time per 100 mL (sec) were plotted, and the change in the pouring time was measured. With the number of samples N = 3, the remaining amount was determined as an average value.

  As a result, in the comparative sample, it was confirmed that the pouring time suddenly increased and the average remaining amount was about 22% when the pouring amount was around 2300 mL.

  On the other hand, in the present invention, the container is formed by effectively utilizing the inclined surface function for inclining the spout described in (1) and the function for installing the spout position low described in (2) above. When tilted, the average remaining amount was confirmed to be about 1.8%. Furthermore, when the function of pouring while pulling the bag described in the above (3) to the upper part of the box was added, it was confirmed that the average remaining amount was further reduced to about 0.7%.

  From the above results, the effects of the present invention are clear. That is, the present invention is an outer box for storing an inner bag for a bag-in-box provided with a spout, and the outer box includes a front plate, a rear plate, and a back plate that are configured so that a spout can be attached thereto.
