BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package in which processed foods such as sausage and cheese are filled in a cylindrical film, and more particularly, to a cylindrical film package in which a consumer easily opens a film.

11 shows a conventional example of a cylindrical film package filled with processed food such as sausage.

In this kind of package, as shown in the cross-sectional view of FIG. 12, both edge portions 1a and 1b of the film 1, such as vinylidene chloride, are overlapped, and the combined portion is a high frequency welding or The welding line S is formed by welding by ultrasonic welding means, etc., and the cylindrical packaging cylinder 10a is formed by this.

In the case of sausage, processed meat is filled in this cylindrical packaging container 10a, and in the case of stick cheese, the process tooth is filled in the cylindrical packaging container 10a.

And both ends of the longitudinal direction of the packaging container 10a are sleepy, and the sleepy part is tightened and closed by the metal claw 2, such as aluminum.

For example, in the case of sausage, after processing meat is filled in the packaging container 10a, it transfers to a boiler process.

In this boiler process, since the internal pressure of the packaging cylinder 10a rises, tension | tensile_strength arises in the film 1, and this tension is shown by the arrow F in FIG. 12 with respect to the welding line S. FIG. It acts in the direction shown.

However, in this conventional example, as shown in FIG. 12, the film edge parts 1a and 1b overlap each other in substantially planar state, and are welded.

Therefore, even if the force indicated by (F) with respect to the welding line S acts by the film tension, the welding strength of the welding line S with respect to this force F is high enough, and a packaging container is used in a voile process. Destruction of (10a) is less likely to occur.

However, in the cylindrical film package described above, in the case where the film 1 is to be opened and opened, the welding line S is applied except that the film edge 1a protruding outward from the welding line S is held by a finger. There is no pod to tear off.

However, since the film magnetic field part 1a which protrudes outward of the packaging container 10a is very short, it is difficult to reliably give this film edge part 1a with a finger.

Therefore, it is impossible to open | release the film 1 from the part of the film edge part 1a.

Therefore, when a consumer wants to open the film 1, it is necessary to cut out the film 1, for example, by a knife etc., and to tear open the film by using this cut as a pod, and to peel off the film from the contents.

As described above, when there is no knife or the like nearby, peeling off the film 1 from the contents is very difficult.

In the case of a relatively small cylindrical film package such as a stick cheese or the like, an opening tape colored in red or the like is attached, and the film 1 is torn by pulling the opening tape.

However, since the opening tape is more expensive than other packaging films and the like, the conventional packaging body which uses this with a long dimension has a high cost and is not economical.

In addition, the tear tape used in conventional stick cheese or the like is attached over the entire length of the cylindrical film package in the longitudinal direction, and its ends are fastened together with the film 1 by the clip 2. It is common.

Therefore, when the tear tape is pulled away from the packaging container 10a, both ends thereof pull the clip 2, and the entire packaging container 10a bends in a bow shape, and there is a drawback in that the contents are deformed.

The present invention has been made to solve the above-mentioned conventional problems, and it is possible to easily open and tear the film without providing an opening tape, and furthermore, the welding strength between the films can be sufficiently increased, and in the boiling process in the case of sausage, etc. It is an object of the present invention to provide a cylindrical film package (the contents of which are filled in a packaging container and both ends thereof are tightened by clips) to withstand the increase in internal pressure.

The present invention is a film packaging body in which the edges of the film are welded to each other to form a cylindrical packaging container, the processed food is filled in the cylindrical packaging container, and both ends in the longitudinal direction of the packaging container are blocked. The edges of the film are joined to the inner surface of the packaging container in a bonded state so as to be in contact with each other, so that the welded portion is welded by the first welding line, and further extends outward from the first welding line. The two film edges together are joined together to the outer surface of the packaging container, and the two film edge portions and the film forming the packaging container are welded together by a second welding line. The welding line is formed with an intermittent portion.

In addition, in said description, the notch (cutout part) is formed in the film edge part in the 2nd weldable intermittent part.

In this cylindrical film packaging body, the film edge is held by a finger at the intermittent part of the second welding line (the part without welding by the second welding line), and the part is pulled off and peeled off, thereby removing the outside of the packaging container. The two film edges bonded to the surface are peeled off from the second welding line, and in some cases, the two film edges are peeled off from the first welding line, thereby forming a packaging container of this part. It can tear off the film.

In this manner, the two film edge portions can exhibit substantially the same function as the opening tape provided separately from the film constituting the packaging container in the prior art, and the film of the packaging container can be peeled off by pulling off the film edge portion. This makes it possible to create a pod that can strip the film from the contents.

Preferably, when the notch (cutout) is placed in the film edge portion at the intermittent portion of the second welding line, the film edge portion can be divided at this portion, and the film edge portion is easily peeled off from the packaging container.

In addition, the film edges are bonded and welded together in a bonded state where the inner surfaces are joined to each other by the first welding line, but again, the film edge portion extending outwardly from the welding line is formed on the outer surface of the packaging container. Since it is welded by the welding line of 2, the welding strength of a film becomes very high.

Therefore, as in the case of sausage, even if the inner pressure of the packaging container rises in a boil process or the like and tension is generated in the film, the welded portion can withstand the tension sufficiently.

Best Mode for Carrying Out the Invention Embodiments of the present invention will now be described with reference to the drawings of FIGS. 1 to 10.

1 is a front view showing a cylindrical film package according to a first embodiment of the present invention.

In this embodiment, the film 1, such as a vinylidene chloride system, is wound in a cylindrical shape, and the packaging container 10 is formed.

As shown in Fig. 2, first, the edge portions 1a and 1b of the first film 1 are bonded together in a bonded state so that the inner surfaces of the packaging container 10 and the surfaces continuous with each other are joined together. The encapsulation portion is fin sealed by the _first welding line S ₁ .

Moreover, as shown in FIG. 3, the edges 1a and 1b of the film which protrude outward from the _1st welding line S1 are bent to either side, and the outer side of the packaging container 10 is carried out. The film ₁ , which is joined to the surface and constitutes the edge portions 1a and 1b of the film and the packaging container 10 in the welding line S ₂ , is made of three pieces together and is formed by high frequency or ultrasonic waves. Welded.

As shown in FIG. 1, the welding line S2 of FIG. ₂ has the intermittent part 1 (part in which 2nd welding is not performed) in the middle.

And the notch (cutout part) 3 is provided in the part of this intermittent part 1.

In the case of sausage, processed meat is filled in the cylindrical packaging container 10 mentioned above, and in the case of stick cheese, the process cheese is filled in the packaging container 10 inside.

And both ends of the longitudinal direction of the packaging container 10 are tightened, for example, it is clamped by the metal clip 2 etc. by aluminum etc., and is blocked.

4 shows an example of an apparatus for forming the packaging container 10.

Reference numeral 11 denotes a stepper nozzle, in which processed meat and the like are charged by the stepper nozzle 11.

On the outer circumference of the stepper nozzle 11, a film forming member 12 is provided.

The strip-shaped film 1 is supplied through the supply rollers 13 and 14 and is molded into a cylindrical shape by the film forming member 12.

The molding member 12 is provided with a pair of guide members 12a and 12b facing each other at intervals, and the guide members 12a and 12b are provided with the edge portions 1a of the film 1. (1b) is merged into the enclosed state.

The high frequency electrodes 15 and 16 face each other below the forming member 12. (15 is a positive electrode and 16 is a negative electrode).

After the edge portions 1a and 1b of the endless-cylinder package 10 formed into a cylindrical shape are joined in the assembled state by the guide members 12a and 12b, the high frequency electrodes 15 and 16 ), Magnetic field portions 1a and 1b of the film are linearly welded to form a first welding line S ₁ as shown in FIG.

Furthermore, further high frequency electrodes 17 and 18 are provided below (17 is a positive electrode and 18 is a negative electrode).

One high frequency electrode 17 faces the outside of the film 1 to be sent out, and the other high frequency electrode 18 faces the inside of the film 1 to be sent.

The film edge portions 1a and 1b after the _first welding line S ₁ is formed by the high frequency electrodes 15 and 16 located above are joined to the outer surface of the packaging container 10. Bend to either side.

And the edge parts 1a, 1b, and the packaging container 10 of this film are formed by the high frequency electrodes 17 and 18, and 3 sheets of the film 1 are welded together in a linear state, Figure 3 is a second chakseon (S ₂₎ for forming shown in.

Reference numerals 19 and 20 denote transfer rollers, and the packaging cylinder 10 is continuously discharged downward by the transfer rollers 19 and 20.

At the time of forming the above-mentioned second welding line S ₂ , by intermittently stopping the current supplied to the high frequency electrode 17 (both electrodes), the intermittent portion 1 shown in FIG. It is possible to form a portion where welding is not performed.

In addition, the fourth, but it is also omitted from the high-frequency electrode 15, 16 and to install a guide plate provided between the high frequency electrode 17, 18, chakseon for of claim 1 (S ₁₎ is formed, When the magnetic field parts 1a and 1b of the film later are folded and bent to one side by this guide plate and folded to the outside surface of the film 1, the high frequency electrodes 17 and 18 cause the second to be folded. It is easy to form the welding line S _{2 of} .

Looking at this relationship with reference to FIGS. 13 and 14, the film 1 is supplied in a guided state by the feed roller 14 so that the film 1 is formed through the inner inner surface of the upper edge of the molding member 12. It is reversed and can be pulled out downward through the inner surface of the molding member 12. At this time, the inverted portion of the cylindrical portion of the intermediate forming member 12 of the film 1 inverted by the upper edge of the forming member 12 becomes a cylindrical packaging box 10 to move downward.

In addition, the molding member 12 and the guide pieces 12a and 12b extend in an equilibrium, and the film 1 inverted by the respective upper edges of the guide pieces 12a and 12b is in the assembled state. The edges 1a and 1b of the film 1 put into the enclosed state are sealed by the high frequency electrodes 15 and 16 to form a first welding line S ₁ . Done.

The magnetic field portions 1a and 1b of the film 1 bonded by the _first welding line S ₁ reach the surface of the package 10 and are separated by the high frequency electrodes 17 and 18. The film 1 constituting the edge portions 1a and 1b of the film 1 and the packaging container 10 is narrowed, and three films are welded by the high frequency electrodes 17 and 18. the first seal is formed in two line (S ₂₎ as possible.

Then, the contents are supplied from the stepper nozzle 11 to the packaging container 10 formed in a cylindrical shape, and the metal clip 2 is provided by a clipping device installed further down the transfer rollers 19 and 20. It is carried out, and it cuts off and cut | disconnects for each packaging container, and the cylindrical film package as shown in FIG. 1 is formed.

In addition, although the notch 3 shown in FIG. 1 can be provided after a package is fully manufactured, the apparatus shown in FIG. 4 is equipped with the apparatus which forms a notch, and the 1st welding line S _{1 is} provided. It is also possible to automatically form the notch 3 between this formation and the formation of the second welding line S ₂ .

Next, an example of an operation for peeling off the film 1 from the contents will be described in the cylindrical film packaging body shown in FIG. 1 (where the contents are filled in the packaging container 10 and both ends thereof are clipped). do. First, a finger is put in the intermittent part 1 of the _2nd welding line S2, and it cut | disconnects to the edge parts 1a and 1b of a film from the notch 3 part.

Then, as shown in Fig. 5, when the edges 1a and 1b of the film are pulled along the welding lines S ₁ and S ₂ , the edges 1a and 1b of the film are drawn. The tape is tape-shaped and separated from the film 1 to be peeled off.

Thereby, the film 1 of the packaging container 10 is torn off.

To explain this in more detail, first, the part shown by (A) in FIG. 3 is torn by pulling edges 1a and 1b of the film.

That is, since the packaging container 10 side is one film with respect to the edge parts 1a and 1b of the two films pulled by a finger, it wraps by pulling the film edge parts 1a and 1b. It is torn at the portion of chakseon (S ₂₎ for one piece of the film (1) on the shellside.

Subsequently, the edge portions 1a and 1b of the film are pulled so that the edge portions 1a and 1b of the film are also wrapped in the weld line S ₁ shown in FIG. 3 in FIG. It is separated from the film 1 of the barrel 10.

Thus, as shown in Fig. 5, the edge portions 1a and 1b of the film are pulled off in the tape shape.

In some cases, the film 1 constituting the packaging container 10 is torn not only in the A portion but also in the B portion.

Therefore, as the edge portions 1a and 1b of the film are pulled off and peeled off in a tape shape, the tearing of the film 1 constituting the packaging container 10 is enlarged, and the contents are exposed.

Moreover, the method shown in FIG. 6 is also effective in peeling off the film 1 in this cylindrical film package.

This method first divides the film edge portions 1a and 1b from the portion of the notch 3 with a finger.

When pulled out from the packaging container 10 indicated by (D) among the edge portions 1a and 1b of the film, the film 1 constituting the packaging container 10 as described above is at least FIG. It is torn into the part indicated by (A).

After that, when the end of the package is pressed with a finger to inflate the contents, as shown in FIG. 6, the torn portions of the film 1 are enlarged to expose the contents.

In addition, what was shown in FIG. 5 and FIG. 6 is only an example of the opening method of the package shown in FIG. 1, and can be opened by any other method.

That is, the film 1 of the packaging container 10 can be easily torn open by breaking the edges 1a and 1b of the film from the notch 3 with the intermittent part 1 of the welding line S ₂ . do.

7 and 8 show a second embodiment of the present invention.

In this embodiment, the notch shown by the code | symbol 3 in FIG. 1 is not provided in the intermittent part 1 of the _2nd welding line S2.

However, even if the notch 3 is not provided, the work of tearing off the film 1 is easy.

As an example of the method, the edges 1a and 1b of the film are held by fingers at the portion of the intermittent portion 1 of the _second welding line S ₂ , and the edge of the film as shown in FIG. 8. The parts 1a and 1b are pulled out and peeled off.

For this reason, the film 1 of the packaging container 10 is torn at the welding line S ₂ part and, in some cases, the welding line S ₁ part, and the contents are exposed.

Even in such a structure in which the notch 3 is not provided, the work that can tear open the film 1 is easy.

In the embodiment shown in FIGS. 1 to 8 described above, the magnetic field portions 1a and 1b of the film constituting the packaging container 10 are formed of the first welding line S ₁ and the second welding line. by for chakseon (S ₂₎ is welded in two places.

As shown in Fig. 2, in the case where only the edge portions 1a and 1b of the film are joined together and welded with one welding line S ₁ , the force in the direction indicated by (F) The strength of the welding line S ₁ is weak.

On the other hand, in the said Example, as shown in FIG. 3, since the _2nd welding line S2 is provided in addition to the _1st welding line S1, welding strength is high.

Therefore, as in the case of sausage, the process is shifted to the visible process after completion of packaging, and the internal pressure is increased to increase the film tension, so that the welded portion can exhibit sufficient strength even if the force in the (F) direction is applied to the welded portion.

That is, in the case of simply being brought together in the assembled state, the force F due to the film tension acts as a force to pull off the edge portions 1a and 1b of the film to each other, whereby The welding line S ₁ is easily broken.

However, in the case of the present invention in which the _second welding line S ₂ is formed, the edges 1a and 1b of the film and the film of the packaging box in the _second welding line S ₂ . Since the force (F) acts in the direction of sliding the films so as to be shifted from each other in a state of being in close contact with each other in the state of overlapping each other in 1), the second welding line (S ₂ ) by this force (F) alone. The break does not occur.

In addition, the strength of the welded portion becomes very high by both of the _second welded line S ₂ and the first welded line S ₁ .

In addition, when it is necessary to further increase the strength of the welded portion, as shown in FIG. 9, a weld line is interposed between the edge portions 1a and 1b of the film via the film tape 6 for reinforcement. In (S ₁ ) and (S ₂ ), it is also possible to weld the film tape 6 together.

As this film tape 6, it is also possible to use the sealing tape conventionally used as it is.

Thus, by providing the reinforcing film tape 6, the number of sheets welded at the weld line S ₁ and S ₂ part can be increased, and welding strength by a high frequency etc. can be improved.

Alternatively, the 10 degree as such, the addition of the film tape (6) of the reinforcement on the outside of the edge portion (1a) of the film, chakseon for the film tape 6 (S ₁₎ and (S ₂₎ shown in Fig. The welding strength can also be increased by welding at.

As described above, according to the present invention, the edges of the film forming the cylindrical packaging container are joined together and fused together, and at the same time, the edges of the film are further along the outer surface of the film of the packaging container. The second welding line is formed, and the intermittent part (defect part) is provided in the middle of the second welding line. Therefore, the edge of the film is held by the finger at the intermittent part of the second welding line. By pulling off, the film can be easily torn off and opened, and the film can be easily peeled off from the contents.

In addition, since two welding lines are formed, they are joined in a bonded state, whereby the strength of the welded portion can be increased as compared with the case where welding is desired.

Therefore, even if the internal pressure rises in the boiling process or the like in the case of sausage, the packaging container is not destroyed at the welded portion.
