Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an improvement in a bag-in-box type container with a spout.

0002

[Conventional technology]

An inner bag made of resin film, etc. on an outer container such as a cardboard box or cardboard box. A so-called bag-in-box type container with a built-in container is used for alcohol, juice, and wine. It is widely used as a container for filling beverages such as milk, mineral water, etc. Recently, they have also been attracting attention as containers for filling liquid detergents and powders.

0003 This means that although the container is light, it can be filled with a relatively large amount of liquid or powder. This is because the container itself can be stored and transported in a folded state. Therefore, it is less bulky than glass bottles or metal cans, making it easier to use. This is because the benefits are great.

0004 On the other hand, it is well known that garbage countermeasures have become an urgent urban issue. Even for bag-in-box type containers, the outer container is made of paper such as cardboard and resin film. The inner bag made of film is separated, the paper of the outer container is recycled and reused, and the resin of the spout and inner bag are recycled and reused. Trying to reduce the amount of garbage by treating only film as plastic waste There is momentum. For this reason, the inner bag and outer container are partially connected so that they can be separated and disposed of easily. A method of keeping them together is used.

[0005] For example, in the mounting structure of the spout 3, as shown in Fig. 5, the outer container 1 and the inner bag 2 are A spout mounting hole 15 is drilled where the spout 3 is partially joined, and the spout barrel of the spout 3 is inserted here. 31 protrudes from the inside to the outside, and the flange 32 is heat-sealed to the inner surface of the inner bag 2. The outer container 1 made of cardboard or the like is bonded to the inner bag 2 made of resin film. A device has been devised so that the and resin plug 3 can be easily separated.

[0006]

[Problem that the idea aims to solve]

However, in the container with the spout stopper of the above configuration, the spout 3 is sealed. The cap 4 must be screwed onto the projecting tube 31 with a rotational torque of a certain level or more. , since the outer container 1 and the inner bag 2 are only partially connected, the spout itself may not rotate. The spout attachment part of the inner bag 2 may be twisted and peeled off from the inner surface of the outer container 1, or There was a problem in that the pouring tube 31 could not be reliably screwed together and sealed. In addition, to prevent the spout from rotating when capping, the base of the spout has an uneven surface. There are ideas to fix it with a holder that matches this unevenness, but it requires a special jig to fix it. There are problems such as poor usability, such as having to be fixed easily and reliably. There was a strong desire to devise a container with a stopper that could be sealed tightly.

[0007]

[Means to solve the problem]

This invention was devised to solve the problems of the prior art described above, and the inner bag is In a bag-in-box type container with a built-in spout, the spout The spout forming the spout connects the spout barrel and the fixing flange, which can be sealed by screwing the cap. the spout tube protrudes from the outer surface of the outer container, and the flange end is in the direction in which the cap is screwed. contacting at least a portion of the boundary between the spout fixing surface and the adjacent surface of the outer container in an unrotatable manner. The present invention provides a container with a pouring spout, which is fixed with a spout.

[0008]

[Effect]

The rotational torque that is applied to the dispensing barrel of the spout when the cap is screwed together is applied to the spout fixing surface and the adjacent surface. It is securely received by the flange end which is fixed in contact with the boundary between the The spout itself does not rotate due to the rotational torque during capping. others Otherwise, the spout attachment part of the inner bag may become twisted and peeled off from the inner surface of the outer container, or the spout The problems of the prior art, such as the inability to reliably seal the stopper, are solved.

[0009]

【Example】

To explain one embodiment based on FIGS. 1 and 2, the outer container 1 is light and has a low rigidity ratio. It is made of a relatively large material, such as cardboard, and has a built-in The inner bag 2 is made of polyethylene and can be filled with liquid and can be heat-sealed. It is made of polyolefin resin such as resin. Outer container 1 and inner bag 2 are as appropriate. For example, the four locations on the circumferential side indicated by the symbol S and the plug fixing flat where the plug 3 is attached. It is bonded to the surface portion 11 at two locations, making it easier for the inner bag 2 to fit therein.

0010 The spout 3 can also be heat-sealed with the inner bag 2 using polyolefin such as polyethylene resin. The spouting tube 31 is made of resin and is inserted into the spout installation hole 15 of the container from the inside to the outside. The upper surface of the flange 32 is heat-sealed to the inner surface of the inner bag 2 to secure it. It is. The pouring tube 31 has a structure in which the cap 4 is screwed together and sealed, and the flange 3 2 is formed into a straight line on three sides of the outer periphery, and this straight part 33 is where the spout attachment hole 15 is formed. Boundary 121 between the cut-out spout fixing plane part 11 and the adjacent plane part 12, and the adjacent plane part 13 and the boundary 141 with the adjacent plane part 14, respectively. has been done.

[0011] Therefore, the rotational torque when screwing the cap 4 onto the spout barrel 31 of the spout 3 is as follows: Straight line portion of flange 32 fixed in contact with three boundaries 121, 131, 141 33, so the spout 3 itself will not rotate during capping. It does not rotate due to torque. Therefore, the inner bag 2 is twisted from the inner surface of the outer container 1. The cap 4 can be rotated sufficiently on the spout tube 31 to prevent it from peeling off. Since the capping is performed with torque, the sealing of the spout 3 is ensured.

0012 Next, to explain an example of forming a container with a spout having the above configuration, the upper part is still open. Store the inner bag 2 in the open outer container 1 with the top open, and then open it at the appropriate location. The container 1 and the inner bag 2 are joined. In this case, the four locations on the circumferential side indicated by the symbol S and the mouth After joining the plug 3 with adhesive at two locations on the plug fixing plane part 11, A spout mounting hole 15 is drilled at a predetermined position in the spout fixing flat part 11, and the spout 3 is inserted into the hole. Insert from the inside to the outside so that the projecting tube 31 protrudes to the outside, and insert it from the three sides of the flange 32. The straight line portions 33 each have boundaries 121, 131, and the adjacent flat portions of the spout fixing flat portion 11, respectively. 141, and the upper surface of the flange 32 is heat-shielded on the inner surface of the inner bag 2. to fix the spout 3. Finally, screw the cap 4 onto the spout tube 31 and Seal it tightly.

[0013] Fill the inner bag 2 with the desired contents from the upper open end, and heat seal this open end. Seal by appropriate means such as. Then, align the opening of the outer container 1 with the predetermined lines. When the inner container is folded along the sides and sealed by heat sealing, pasting with glue, etc. A bag-in-box type container with a spout in which the bag 2 is built-in is completed. In addition, a container with an empty inner bag 2 built into the outer container 1 is completed, and it can be used when necessary. Remove the cap 4, fill the dispensing tube 31 with the desired contents, and cap it again. It is also possible to have a structure that is sealed.

[0014] FIG. 3 shows an example of a container in which a spout 3 is attached to the outer surface of the inner bag 2. this In this case, an inner bag 2 with a spout 3 on the outside is made first, and this inner bag 2 is attached with a spout. It is stored in the outer container 1 with a hole 15, and the spout tube 31 is removed from the spout attachment hole 15. The straight part 33 of the flange 32 is brought into contact with the boundary 121 and the straight part 33 of the flange 32 is brought into contact with the boundary 121 to The surface and the inner surface of the outer container 1 are fixed using adhesive or the like. Inner bag 2 and mouth plug The connection between the outer container 1 and the flange 32 is made such that the outer container 1 and the flange 32 can be easily separated from the outer container 1 after use. The garment is partially glued, not solid glue. This type of container also has a spout on inner bag 2. After filling the contents through an opening provided on the outside, this opening may be closed to seal the container. , a completed empty inner bag 2 built into the outer container 1, and a spout tube 31 with the cap 4 removed. It can also be filled from

[0015] The flange 32 of the spout 3 may have the shape shown in FIG. 4 or the like. In Figure 4 In (a), the four straight portions 33 of the rectangular flange 32 are fixed to the spout. The surface part is brought into contact with the boundary between the surface part and the surrounding flat part at four places, as shown in (b) and ( c) means that two straight parts 33 are brought into contact with two parts of the boundary, as shown in the figure. (d) shows the fixing part 34 extending in all directions at the part closest to the boundary and the plug mounting hole. It is formed so that it can come into contact at a part that is offset counterclockwise from the position. In addition , the spout 3 shown in (d) has a flange shape when the cap 4 is screwed onto the cap 4 with a right-hand screw. This indicates that when the cap 4 is screwed in with the left-hand screw, it will shift clockwise. An attachment portion 34 is provided so as to abut at the location where the attachment portion 34 is attached.

[0016] Note that the container with spout according to the present invention is not limited to the above embodiment. Appropriate changes can be made without departing from the gist of the claims for utility model registration. It is. For example, the materials of the outer container 1, inner bag 2, spout 3, and cap 4 may be changed as appropriate. Therefore, if the object to be stored is powder, the inner bag 2 may be made of paper or the like. good. Further, a sealing portion may be formed in the spout tube 31 of the spout 3 so that it can be opened. However, in the case of a container in which the spout 3 is attached to the outer surface of the inner container, the spout 31 is The part of the inner bag 2 is left unopened, and the opening means for the inner bag 2 is installed inside the spout tube 31. It is also possible to store it.

[0017]

[Effect of the idea]

As explained above, the container with spout of the present invention is a container with an inner bag built into the outer container. In a box-in-box type container with a spout, the spout that forms the spout is locked. It has a spout barrel and a fixing flange that can be sealed by screwing a cap, and the spout barrel is The flange end protrudes from the outer surface of the outer container, and the flange end cannot rotate in the screwing direction of the cap. It is fixed in contact with at least a part of the boundary between the spout fixing surface and the adjacent surface of the device. The outer container and inner bag are partially glued together to make it easier to separate the inner bag and spout from the outer bag after use. Even if you do this, the rotational torque when screwing the cap onto the dispensing tube is the same as the flat part fixing the spout. It is securely received by the flange end which is fixed in contact with the boundary with the adjacent plane part. It will be done. Therefore, the spout itself may rotate due to the rotational torque during capping. Since the inner bag does not have to be twisted and peeled off from the outer container, there is no need to remove the cap. The spout is screwed onto the spout tube with sufficient rotational torque, and the spout is reliably sealed.
