Description

  The present invention relates to a bag-in-box and a bag-in-box member in which a bag is stored in a box.

  The bag-in-box is composed of a bag for storing liquid and the like and a box for storing the bag (for example, Patent Document 1). And the spout of a bag is taken out from the spout taking-out hole formed in one side of the box.

  FIG. 9 is a view showing a surface on which a spout take-out hole 50 having a conventional shape is formed. On this surface, a circular spout take-out hole 50 for passing a spout and a plurality of slits 51 extending radially from the outer periphery of the spout take-out hole 50 are formed.

  In order to take out the spout from the box, first, the tongue 52 is bent to the outside of the box and the spout take-out hole 50 is expanded. Then, the spout is taken out from the spout take-out hole 50 through the finger into the box. Thereafter, the tongue 52 is returned to the original position to fix the spout.

  However, the bag with the spout take-out hole 50 having such a shape has the following problems. Since the box is required to have high pressure strength, the box is often thick and hard, and it is difficult to bend the tongue 52 to the outside. Further, since the bent tongue 52 is naturally restored to the original position, it may be difficult to take out the spout by inserting a finger from the spout takeout hole 50. Furthermore, since the spout take-out hole 50 and the spout are approximately the same size, it is difficult to visually check the remaining amount of contents in the bag. As described above, the conventional bag-in-box is not always easy to use.

  The present invention has been made in view of such problems, and the object of the present invention is to solve at least a part of the above-described problems and to provide a user-friendly bag-in-box and such a bag-in-box. It is to provide a member.

  Embodiments according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a perspective view schematically showing a bag-in-box in use. The bag-in-box is composed of a bag 1 for storing liquid and the box 2 for storing the bag 1. The spout 11 of the bag 1 is taken out from the spout take-out hole 3 formed in the box 2. One of the features of this embodiment is the shape of the spout take-out hole 3, which will be described in detail later.

  FIG. 2 is a side view schematically showing the bag 1, and enlarges the vicinity of the spout 11. The bag 1 has a cap 10, a spout 11 for taking in and out the contents, and a pouch 12 filled with the contents.

  The spout 11 includes a bank part 111 and a groove part 112. The inside of the bank portion 111 and the groove portion 112 is hollow, and the contents can be taken in and out by removing the cap 10. The cross section of the groove portion 112 is substantially circular, and the diameter d0 thereof is, for example, 48 mm, which is smaller than the bank portion 111 and the pouch 12. The thickness 112 of the groove 112 (that is, the distance between the bank portion 111 and the pouch 12) t0 is, for example, 9 mm.

  The pouch 12 may be solid. Further, the pouch 12 may be formed of a deformable flexible material such as vinyl, and swells when the contents are inserted, and may be deflated as the contents decrease. A hole is formed in a part of the pouch 12 and is connected to the cavity of the groove 112 in the spout 11.

  FIG. 3 is a side view schematically showing the box 2. The box 2 is also called a carton and is made of cardboard, for example. In order to achieve high compressive strength, the thickness of the box 2 is desirably about 5 to 8 mm. The box 2 has four side surfaces 21a to 21d (only the front side surfaces 21a and 21b are visible in the figure), a lower surface (not shown in FIG. 3), and upper surfaces 22a to 22d extending from the side surfaces 21a to 21d. 22d.

  The upper surfaces 22a and 22c are approximately half the size of the lower surface, and substantially semicircular openings 23a and 23c are formed in portions of the upper surfaces 22a and 22c so as to face each other. Therefore, when the upper surfaces 22a and 22c are closed, a substantially circular opening 23 is formed. After the upper surfaces 22a and 22c are closed, portions other than the opening 23 may be bonded to each other with a tape.

The upper surfaces 22b and 22d are also approximately half the size of the lower surface, and a spout take-out hole 3 is formed in the upper surface 22b. The thickness t1 of the upper surface 22b is, for example, 8 mm, which is slightly smaller than the thickness t0 of the groove 112 of the spout 11. After the upper surfaces 22a and 22c are closed, the upper surfaces 22b and 22d are closed so as to overlap them. Again, after the upper surfaces 22b and 22d are closed, they may be bonded together with a tape.
By closing the upper surfaces 22a to 22d in this way, the box 2 has a substantially rectangular parallelepiped shape.

  The spout 11 of the bag 1 can be taken out through the opening 23 and the spout take-out hole 3. In the present embodiment, the spout take-out hole 3 has a shape through which a finger can pass so that the spout 11 can be easily taken out. Hereinafter, this point will be described in detail.

  3 and the following description show an example in which the spout take-out hole 3 is formed on one surface of the box 2, but a flap (plate) having a surface on which the spout take-out hole 3 is formed as a separate member from the box 2. ) May be used. The box 2 in which the spout take-out hole 3 is formed and the flap in which the spout take-out hole 3 is formed (separate from the box) are collectively referred to as a “bag-in-box member”.

  FIG. 4 is a top view of the upper surface 22b of the bag 1 in which the spout take-out hole 3 is formed. The spout extraction hole 3 is composed of one central opening (first opening) 31 and a plurality of peripheral openings (second openings) 32. A plurality of slits 33 are formed radially on the upper surface 22b from the central opening 31.

  The central opening 31 is an opening for allowing the spout 11 to pass therethrough, and is positioned substantially at the center of the spout extraction hole 3. The shape of the central opening 31 is a shape that matches the groove 112 of the spout 11, and when the cross section of the groove 112 is circular, the central opening 31 is also circular. The diameter d1 of the central opening 31 is slightly larger (for example, about 1 to 3 mm) than the diameter d0 of the groove portion 112 and smaller than the bank portion 111, for example 50 mm.

  The peripheral opening 32 is an opening through which a finger passes, and is positioned at substantially equal intervals around the central opening 31. FIG. 4 shows an example in which four peripheral openings 32 for passing the thumb, index finger, middle finger and ring finger are formed. Each of the peripheral openings 32 extends radially from a part of the outer periphery of the central opening 31 toward the edge of the upper surface 22b. As shown in the figure, the shape of the peripheral opening 32 includes two parallel sides that extend in the direction of 45 degrees obliquely from the outer periphery of the central opening 31 to the edge of the upper surface 22b, and one side that connects these two sides. The length a1 of each side may be equal, and it is desirable that the size is suitable for putting a finger, for example, 10 mm or more. However, the shape of the peripheral opening 32 is not particularly limited, and may be a curved shape, for example.

  The slit 33 is between the peripheral opening 32 and the peripheral opening 32, and extends radially from a part of the outer periphery of the central opening 31 toward the edge of the upper surface 22 b of the bag 1. In FIG. 4, one slit 33 is formed between the peripheral opening 32 and the peripheral opening 32, but the number is not particularly limited. A gap 34 is formed between the peripheral opening 32 and the slit 33. The length a2 of one side of the tongue portion 34, that is, the distance between the outermost point of the slit 33 and the corner of the peripheral opening 32 is preferably, for example, 5 mm or more so that the tongue portion 34 can be easily pinched and bent.

  It should be noted that when the bag-in-box is placed, the four peripheral openings 32 are set to “X” in the oblique 45-degree direction so that not the peripheral openings 32 but the tongues 34 or the slits 33 are arranged below the spout 11. It is desirable to provide it in a “shape”. This is because the spout 11 can support the spout 11 in the vertical direction from below, and the spout 11 is stabilized. Of course, depending on the application, the four peripheral openings 32 may be provided in a “+” shape vertically and horizontally.

  Next, a procedure for taking out the spout 11 of the bag 1 stored in the box 2 will be described. First, it is assumed that the entire bag 1 including the spout 11 is stored in the box 2.

  First, the tongue portion 34 is picked and bent to the outside of the box 2. In the present embodiment, since the peripheral opening 32 is provided, the tongue portion 34 can be easily picked even when the box 2 is thick and hard. Further, since the number of the tongue portions 34 is smaller than that of the structure shown in FIG. 9, the bending work can be reduced.

  Next, a finger is passed through each of the peripheral openings 32, and the spout 11 in the bag 1 is grasped by the finger. Then, the spout 11 is pulled out of the box 2 from the central opening 31 until the groove 112 of the spout 11 is located on the same plane as the central opening 31, and the finger is pulled out from the peripheral opening 32. In the present embodiment, since the finger can pass through the peripheral opening 32, the spout 11 can be easily pulled out.

In this state, the tongue part 34 is restored. At this time, the position of the spout 11 can be finely adjusted by passing the finger through the peripheral opening 32 so that the spout 11 is securely fixed by the tongue portion 34.
Thus, the spout 11 is taken out and the bag 1 is fixed to the box 2.

  FIG. 5 is a side view schematically showing the fixed spout 11. As illustrated, the tongue portion 34 is in contact with or close to the groove portion 112. Since the diameter d1 of the central opening 31 is slightly larger than the diameter d0 of the groove 112, the tongue 34 can be fixed with the groove 112 interposed therebetween. Further, since the thickness t1 of the tongue portion 34 (that is, one surface of the box 2) is slightly smaller than the thickness t0 of the groove portion 112, the tongue portion 34 is fixed between the bank portion 111 and the pouch 12.

In this way, the spout 11 is taken out from the spout take-out hole 3 and the bag 1 is fixed to the box 2. Thereby, the content filled in the pouch 12 can be taken out from the spout 11. In this state, the bag 1 can be seen from the peripheral opening 32, which is convenient for visually confirming the remaining amount of the contents.
Hereinafter, some modifications of FIG. 4 will be described focusing on differences from FIG.

  FIG. 6 is a top view of the upper surface 22a of the bag 1 in which the spout take-out hole 3 'according to the first modification is formed. The spout take-out hole 3 'includes a central opening 31 and two peripheral openings 32 arranged at equal intervals. Each peripheral opening 32 is for passing two fingers (for example, thumb and index finger). In FIG. 6, three slits 33 are formed at equal intervals between the peripheral opening 32 and the peripheral opening 32. In this case, not only between the peripheral opening 32 and the slit 33, but also between the slit 33 and the slit 33 becomes the tongue portion 34. According to this configuration, the number of fingers that can be passed is reduced as compared with FIG. 4, but since the area where the tongue portion 34 and the groove portion 112 of the spout 11 are in contact with each other is increased, the spout 11 can be fixed more stably.

  FIG. 7 is a top view of the upper surface 22a of the bag 1 in which the spout take-out hole 3 '' is formed as the second modified example. The spout take-out hole 3 is composed of a central opening 31 and three peripheral openings 32 arranged at equal intervals. Each peripheral opening 32 is for passing three fingers (for example, thumb, index finger and middle finger). In FIG. 7, one slit 33 is formed between the peripheral opening 32 and the peripheral opening 32. According to this configuration, the number of fingers that can be passed and the fixability of the spout 11 are approximately in the middle of the spout extraction hole 3 in FIG. 3 and the spout extraction hole 3 ′ in FIG. 7.

  3 and the like, the spout take-out hole 3 is formed in advance on one surface of the box 2, but as another embodiment, as shown in FIG. 8, a sewing machine for forming the spout take-out hole on one surface of the box 2 More specifically, a perforation 31a for forming the central opening and a perforation 32a for forming the peripheral opening may be provided. And when taking out the spout 11, you may make it cut the perforations 31a and 32a and form a spout taking-out hole. Alternatively, only the central opening 31 (or only the peripheral opening 32) may be formed in advance, and a perforation 32a (or 31a) for forming the peripheral opening (or central opening) may be provided. Similarly, the perforations for forming the slits may be provided instead of forming the slits 33 in advance. When the perforation is provided, it is desirable to form the perforation so that it can be cut with a pushing force or a pulling force of, for example, 50 N or less in consideration of the pinch force at the female finger tip.

  Thus, in this embodiment, not only the central opening 31 for passing the spout 11 but also the peripheral opening 32 for passing the finger is provided on the surface from which the spout 11 is taken out. For this reason, the spout 11 can be easily taken out, the remaining amount of the contents of the bag 1 can be confirmed, and the usability of the bag in box is improved.

  The embodiment described above is described for the purpose of enabling the person having ordinary knowledge in the technical field to which the present invention belongs to implement the present invention. Various modifications of the above embodiment can be naturally made by those skilled in the art, and the technical idea of the present invention can be applied to other embodiments. Therefore, the present invention should not be limited to the described embodiments, but should be the widest scope according to the technical idea defined by the claims.
