Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a spout forming an entrance and an exit of a wrapper made of a soft synthetic resin for accommodating a liquid or viscous filler. External spout directly bonded to

2. Description of the Related Art A spout is a discharge port for taking out a liquid or a viscous material contained in a soft synthetic resin wrapper, as shown in FIG. Is made of a hard synthetic resin spout 21,
The spout 21 is usually attached to the top or abdomen of FIG. 3 and cuts the spout seal as required to take out the filler from the discharge port 24.
3, a hole 25 was made at a desired location, the spout 21 was inserted from the inside of the wrapper 23, and the edge 25 and the wrapper 23 were heat-sealed to perform the attachment.

The packing bag 23 with the spout 21 is filled with the filling material. However, since the spout 21 must be attached to the packing bag 23 before filling, the spout 21 protrudes, which makes the filling operation difficult. Often accompanied,
Further, there is a problem that it is difficult to assemble the wrappers 23 when they are assembled. The function required for the wrapper 23 is that it be folded into a flat plate when it is not filled, that storage, transportation, display, etc. be easy after filling is completed, and that the packing be easily opened to take out the filling. In addition, after taking out the filling material, it is desired that the space is not taken up even when it is folded into a flat plate and discarded.

[Problems to be Solved by the Invention] Conventionally, spouts are inserted and welded from the inside of the wrapper, and there is no other wrapper with a spout. In addition, if the filling is a sanitary material such as beverages, foodstuffs, or pharmaceuticals, the sanitary cleanliness of the wrapper is required in particular, and it may be contaminated at least by various bacteria. Although it must be done, there is always a danger of being eroded by various germs because it must go through a process such as punching and attaching a spout before completing the wrapper, and there is a need to improve this problem from a sanitary point of view. Was.

[Means for Solving the Problems] A body having a discharge port, a thread provided on an inner surface or an outer surface near a top thereof, and a thin disk-shaped edge provided on a bottom. Using a synthetic resin spout, the spout is heat-sealed to a desired location of a package made by combining a sheet of soft synthetic resin of the same type as the spout with a seal head, and a blade is attached to the package. This was achieved by using a screw or the like to cut the wrapper with the provided lid or stopper so as to make a round hole and take out the filler. An outlet tube was attached to the lid or stopper so that the filler could be taken out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a perspective view illustrating the shape of the external spout according to the embodiment of the present invention. FIG. 2 is a cross-sectional view of the external spout according to the embodiment of the present invention when the spout is attached to a wrapper.
FIG. 3 is a diagram showing a usage example of the external spout according to the embodiment of the present invention.

The external spout 1 of the present invention is a spout 1 made of a hard synthetic resin such as polyethylene (PE) which is integrally molded, and has a thin disk-shaped edge 2 of about 100 μm at its bottom. And the packing 1
The body 3 having a discharge port 9 for discharging 0 is self-standing. The body 3 has a thread 7 provided on the outer surface or the inner surface of the body a so that the thread 7 is engaged with the thread 4 of the lid 5 or the plug 6 so that the lid 5 or the plug 6 is attached to the spout 1. I'm sorry.

The lid 5 or the stopper 6 is not always attached to the spout 1, but is used to take out the filler 10 by cutting the envelope 11 when removing the filler 10 from the envelope 11. The spout 5 or the plug 6 is made of a hard synthetic resin of the same quality as the spout 1 and has a sharpened blade-shaped blade 8 or a metal blade 8 at the tip.

The wrapping bag 11 is formed into a bag shape by heat-sealing both ends and side surfaces of a three-sheet combination sandwiching a nylon sheet 14 between two polyethylene sheets 13 made of a soft synthetic resin. The spout 1 has a bag 11 filled with the filler 10 and an abdomen 2 attached to the abdomen by a heat seal 12.

The edge 2 of the spout 1 is thin, about 100 μm, and is made of polyethylene. The surface sheet 13 of the wrapper 11 is also made of the same polyethylene sheet 13 even if there is a difference between soft and hard. So it is easy to be familiar, fortunately polyethylene has a hard heat deformation temperature of 61-72 ° C,
Since it is soft and has a low temperature of 50 to 58 ° C. as compared with other synthetic resins, heat generated by the seal head can be easily welded to the polyethylene sheet 13 of the wrapper 11 through the edge portion 2. Therefore, the thickness of the edge 2 is desirably as thin as possible. However, if the edge 2 is too thin, the strength of the spout 1 becomes difficult, so that about 100 μm is convenient. A sealing head (not shown) is attached to the wrapping bag 11 thus filled and filled.
Then, the edge 2 of the spout 1 is pressed against the polyethylene sheet 13 and welded, so that the chance of invasion of various bacteria into the filler 10 is reduced accordingly.

The wrapper 11 may be manufactured and filled by a conventionally known vertical pillow bag-filling method.
In this case, the filling material 10 is filled while the wrapping bag 11 is manufactured from three sheets, instead of making a hole in the inner surface of the wrapper 1 and inserting the spout 1 and performing heat sealing to fill the wrapping bag. In addition, since there is no projection of the spout 1, there is an advantage that bag making and filling can be easily performed. In addition, since the prior steps of drilling, inserting a spout, and welding a spout can be omitted when filling and filling the bag, the chances of being infected by various bacteria are reduced accordingly, which is sanitary.

A case where the filler 10 is taken out of the wrapper 11 containing the filler 10 will be described. When the blade 8 of the lid 5 is inserted into the discharge port 4 of the spout 1 and screwed while engaging the thread 7 of the body 3 with the thread 4 of the lid 6, the tip of the blade 8 rotates and the wrapper 11 rotates. The polyethylene sheet 13 and the nylon sheet 14 are cut by the blade 8 and the spout 1
A round hole 16 is formed in the inner zipper 11. If the lid 5 is completely screwed in and its rotation has stopped, the lid 5 is returned and the discharge port 4 is opened, so that the filling 10 can be taken out from the hole 16 formed by the blade 8 through the discharge port 4. At this time, if the extraction pipe 15 is attached to the lid 5 and the spout 1 and the lid 5 and the lid 5 and the extraction pipe 15 are made watertight so as not to leak, if the lid 5 is screwed and stopped, the extraction pipe 15 is passed through the extraction pipe 15. This is advantageous because the filling can be removed.

The external spout described above is not limited to the present embodiment, and various modifications can be made. Although the blade 8 for cutting the zipper is described as being attached to the lid 5 or the stopper 6, the blade 8 may be an integral structure with the lid or stopper 6, or the blade 8 may be attached to the tip of a cylindrical cylinder. The blade portion may be formed in a saw shape. Although the zipper and spout are described as being made of polyethylene, they may be made of another synthetic resin having a low heat distortion temperature, such as nylon, polypropylene, polychlorinated biphenyl and the like.

[Effect of the Invention] Aseptic filling at the time when there is no external spout, as described above, is performed after punching a hole in the wrapper, inserting the spout, and welding the spout by heat sealing. After making the bag and sterilizing it by gamma irradiation, heat sterilization or other sterilization methods on this wrapper, the work such as having to perform aseptic filling was complicated, but using the external spout of the present invention Aseptic filling of the bag can be performed by aseptic filling of the sterilized wrapper, and the wrapper does not have a spout even when the wrapper is filled. The bag filling machine can be simplified. Further, since the packing bag to be filled can be folded into a flat plate, there is an advantage that the storage is easy without requiring a space.

[0015] Sterilization of spouts during aseptic filling involves difficulties, but the other bag-making, filling, and sterilizing operations are simplified, so that they are about 20 to 30 times more than conventional bag-making and filling methods. Cost reduction of about% is expected. Conventionally, it has been used for general foods and beverages as applications, but the use of the external spout of the present invention has many advantages such as expanding to application fields such as medicines, infusions, and medical foods and beverages. .
