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 container formed in a cylindrical shape by a film, and more particularly, to a cylindrical film package in which a consumer tears the film and is easily opened. .

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

In this kind of film package, as shown in the cross-sectional view of FIG. 10, both film frame members 1a and 1b of the film 1, such as vinylidene chloride, are overlapped, and thus the film frame member 1a is overlapped. And 1b are welded by a high frequency welding means, an ultrasonic welding means, etc., and the welding line S is formed, and the cylindrical packaging cylinder 5 is formed by this.

In the case of sausage, processed meat is filled in the cylindrical packaging container 5, and in the case of stick cheese, the process cheese is filled in the cylindrical packaging container 5.

And both ends of the longitudinal direction of the packaging container 5 are tightened, and this clamped part is tightened and blocked by the clip 2 formed of metal, such as aluminum.

For example, in the case of sausage, after processing meat is filled in the packaging container 5, it goes to the boil process.

In this boy process, since the internal pressure of the packaging container 5 increases, tension acts on the film 1. This tension acts on the welding line S. However, as shown in FIG. 10, when the film rim members 1a and 1b overlap each other in a substantially planar state and are welded together, the welding line ( Even if the force indicated by (F) with respect to S) acts, the welding strength of the welding line S with respect to the tooth force F is comparatively high.

Therefore, the packaging container 5 is hardly broken in the part of welding line S in a voile process.

However, as shown in FIG. 11, in the cylindrical film packaging body in which the film frame members 1a and 1b are overlapped and welded in a planar state, the film frame member 1a is located on the outer surface of the packaging container 5. Since the protrusion amount Z from the welding line S of () is short, it becomes impossible to hold | maintain this film frame member 1a with a finger reliably, Moreover, the welding line S other than the film frame member 1a is prevented. Since there is no part which becomes a pod for tearing off, it is very difficult to tear open the film 1.

Therefore, in order for a consumer to tear and open the film 1, for example, she cuts the film 1 by a knife etc., opens the film 1 by making a pod into this cut | disconnected place, and opens the film 1 in the contents. I'm tearing it off.

Therefore, when there is no knife etc. around, it is very difficult to remove the film 1 from the contents.

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

However, since this kind of open tape is expensive, the conventional package using this long dimension is expensive and inefficient.

Moreover, it is common that the tear tape is affixed to the longitudinal length of a package body conventionally, and the both ends are fastened together with the film 1 by the clip 2.

Therefore, when the tear tape is peeled off from the packaging container 5, both ends of the tear tape pull the clips 2 at both ends of the package body and bend in the bow shape of the whole package body, thereby deforming the contents. There are also drawbacks.

In addition, as shown in FIG. 11, the film rim members 1a and 1b of the film 1 forming the packaging container 5 are put together in a joined state in which surfaces continuous from the inner surface of the packaging container 5 are joined to each other. The package body which joins and welds the base parts of film frame member 1a and (b) with each other by welding line S can also be considered.

In the package shown in FIG. 11, since both of the film frame members 1a and 1b protrude from the packaging container 1, the notches are formed on both of the film frame members 1a and 1b. Cut portions), the cut portions are podted to tear the film rim members 1a and 1b together, and the film 1 can be peeled off from the contents relatively easily.

However, in the structure in which the film frame members 1a and 1b are joined and welded together in the assembled state as shown in Fig. 11, when the internal pressure increases in the voile process or the like, and the tension in the circumferential direction occurs in the film 1, This tension force F acts to pull the film frame members 1a and 1b apart from each other.

In addition, the force in the direction in which the film edge members 1a and 1b are pulled and peeled from each other acts as a force for breaking the welding line S. FIG.

Thus, in the structure shown in FIG. 11, the intensity | strength of the part adhered by the welding line S becomes very weak, the internal pressure becomes high in the boiling process, etc. in the case of sausage, and a film packaging container is easily broken from the welding line S part. do.

The present invention is to solve the above-mentioned conventional problems, it is easy to tear open the film forming the packaging container, it is easy to peel off the film from the contents, moreover, it is possible to sufficiently increase the welding strength of the film frame member It is an object of the present invention to provide a cylindrical film package that can sufficiently withstand an increase in the internal pressure in a boil process in the case of sausage.

In the film package filled with the processed food according to the present invention, a cylindrical packaging container is formed by a film, and the processed food is filled in the packaging container, and the film package body is blocked at both ends in the longitudinal direction of the packaging container. In this case, one side of the film frame member of the film formed in a cylindrical shape is superimposed on the outside of the other film frame member so that both film frame members are welded by the first welding line and at the same time the film frame member overlaps outward. The film which forms the packaging container and the film | membrane which the two sheets which were folded back and folded and this back folded and the packaging container were welded together by the 2nd welding line.

In the welding structure of this film, the welding by the 1st welding line is substantially the same as the conventional welding line S shown in FIG. 10, and it is made with respect to the tension F which acts on a film by the increase of internal pressure. The welding line of 1 can exhibit sufficient welding strength.

That is, in the vowel process in which the contents are sausage, when the tension of the film is significant, the force due to the tension is not a direction in which the film is peeled off directly with respect to the first weld line, but the film edge members with respect to the weld line. It acts in the shifted direction (shear direction to the welding line) so as not to overlap each other.

The welding line can exert sufficient strength against the force in the shear direction, and furthermore, the frictional force between the films overlapping the welding portion is also received by sharing a part of the force due to the tension, so as to prevent breakage of the welding line. It will work.

Therefore, this 1st welding line can fully bear the increase of the film tension in a visible process etc ..

When the film of the cylindrical film package is peeled from the contents, a finger is placed on the intermittent portion (the portion where the second welding line is not formed) formed in the second welding line (the second welding line is not formed) and the film edge member folded and folded. And pull this part.

For this reason, a film frame member is peeled off from a 2nd welding line, and the film which forms the packaging container from a 2nd welding line at this time is torn.

In addition, in this case, the film which forms the packaging container is also torn at the 1st welding line part.

Therefore, the film rim member folded back into two sheets exhibits almost the same function as the opening tape formed in a conventional film packaging container. By pulling away from the tang, the pods forming the packaging can be torn and opened.

Further, preferably, when the notch (cutting part) is put in the film rim member in the intermittent part of the second welding line, the film rim member can be separated from the cut part, and the film rim member is easily pulled off.

EXAMPLE

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

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

In this first embodiment, the film 1 such as vinylidene chloride-based or the like is wound in a cylindrical shape to form a packaging container 10.

In the film 1 constituting the packaging container 10, the film edge members 1a and 1b are welded by high frequency welding means or ultrasonic welding means, but two welding lines S are formed by the welding means. ₁ ) and (S ₂ ) are formed.

2 is an enlarged cross-sectional view of a packaging container showing a step of forming a _first welding line S ₁ .

3 is an enlarged cross-sectional view of a packaging container showing a step of forming a _second welding line S ₂ .

First, as shown in FIG. 2, the film rim members 1a and 1b of both sides of the film 1 forming the cylindrical packaging container 10 overlap each other along the curved surface of the packaging container 10 as they are. The packaging container 10 is welded over the entire length of the longitudinal direction by the _1st welding line S1.

Further, after the first welding line S ₁ is formed, as shown in FIG. 3, the film rim member 1a protruding toward the outer surface of the packaging box 10 is folded back and folded to be folded. A second welding line S ₂ is formed slightly inside of (4).

For chakseon of the second (S ₂₎ in which two sheets of folded kkeokyeoseo form a stacked film frame member (1a) and the packing tube (10) being loaded with (1) are welded together three sheets.

As shown in FIG. 1, the film rim member 1a folded and folded in two pieces and welded by the _second welding line S ₂ is folded and folded at both ends of the packaging container 10 as it is. It is clamped by the clip 2.

Therefore, the film edge member 1a is in the state which the cross section is folded and bent as shown in FIG. 3 over the full length of the packaging container 10. As shown in FIG.

Also chakseon (S ₂₎ for the second, as shown in FIG. 1 has the middle of the intermittent portion (ℓ).

This intermittent portion (l) is a portion where the second welding line S ₂ is not formed, and when the second welding line S ₂ is continuously formed by the high frequency welding means, the ultrasonic welding means, or the like for a predetermined short time, This intermittent portion 1 is formed by stopping supply of current to the welding means.

In addition, in the Example of FIG. 1, the notch (cutting part) 3 is formed in the film frame member 1a in the part of this intermittent part l.

When the contents of the film package body are sausages, processed meat is filled in the packaging container 10 formed in a cylindrical shape with the _first welding line S ₁ and the second welding line S _{2 as} described above. .

In the case of stick cheese, the process cheese is filled in the cylindrical packaging container 10 formed as described above.

After the contents are filled, both longitudinal ends of the cylindrical packaging container 10 are tightened and clamped by a clip 2 formed of metal such as aluminum.

The cylindrical packaging cylinder 10 produced with the structure shown in FIG. 1 has a very high welding strength between the film rim members 1a and 1b.

First, in the first welding line S ₁ , the packaging container 10 is formed, and the film frame members 1a and 1b of the film 1 overlap each other in a state along the curved surface of the packaging container 10. It has been cut and welded.

Thus, hangyeongwoo the film tension to increase the internal pressure of the packaging tube (10) increasing in such seem fair, and the force (F) by the film tension shear direction (film frame member (1a) with respect to for chakseon (S ₁₎ (1b) is shifted from each other), but the welding strength of the _first welding line S ₁ by high frequency or ultrasonic wave is strong against the force in the shear direction.

In addition, in the welding part by the _1st welding line S1, since the films overlap each other, the frictional force by the overlap of this film shares a part of said force F.

Therefore, the 1st welding line S ₁ can exhibit sufficient intensity | strength with respect to the increase of film tension.

That is, chakseon (S ₁₎ for the first is the liquid 10 is substantially the same as the conventional chakseon (S) for illustrating the (cross-sectional view of the film package on the conventional cylindrical), and second in this embodiment The strength of the weld line S ₁ of ₁ is equivalent to the conventional weld line shown in FIG.

Even in the conventional example of FIG. 10, since the welding strength in a vowel process etc. is sufficient, even if the internal pressure of the package of this Example rises in a voyage process etc., it is difficult to produce breakage from the weld line S ₁ part, etc. easily. Is the same.

On the other hand, in the case where the film frame members 1a and 1b are joined together and welded as in the conventional example shown in FIG. 11, the force F is to peel off the film from the welding line S. It acts and, therefore, welding strength is low.

With respect to the first welding line S ₁ in the above embodiment, the force F acts as a force in the shear direction, and the frictional force between the films is also exerted, so that the strength against the increase in the internal pressure of the package is determined. It becomes very high compared with the conventional example of 11 degrees.

Further, in this embodiment, since the first welding line S ₁ and the second welding line S ₂ are formed, the welding strength is higher than that in the case of one welding line as in the conventional example of FIG. It is high.

In this manner, the film package of the cylindrical as shown in FIG. 1, there is chakseon (S ₁₎ and the strength of welded portion due to a (S ₂₎ for the film (1) forming the packing tube (10) is very high.

In addition, in the cylindrical film packaging of this embodiment, the film 1 is more easily peeled from the contents than the conventional example shown in FIG.

4 and 5 are front views showing one example of a method of opening the cylindrical film package according to the first embodiment of the present invention.

In the cylindrical film package of the first embodiment shown in FIG. 1, an example of a method of opening and tearing the film 1 from the contents is to insert a finger into the intermittent portion ℓ of the _second welding line S ₂ . This is performed by cutting the film rim member 1a from the cut portion 3.

Pulling along the cut (3) After cutting the film frame member (1a) from a portion, chakseon (S ₁₎ for a film frame member (1a) as shown in FIG. 4 and (S _2), the film frame member ( 1a is tape-shaped and separated from the film 1 forming the packaging container 10, and peeled off.

As a result, the film 1 forming the packaging container 10 is torn.

In more detail, first, the film 1 which forms the packaging container 10 from the _2nd welding line S2 part is torn by pulling the film frame member 1a.

In the portion where the welding line S ₂ is formed, the film edge member 1a pulled by the finger is folded and folded, so that the film 1 of the packaging container 10 is one sheet because the two sheets are stacked. When the film frame member 1a is pulled, the film frame member 1a is not torn, and the single film 1 forming the packaging container 10 is torn.

Subsequently, the film frame member 1a is pulled to separate the film frame member 1a from the film 1 forming the packaging box 10 at the portion of the _first welding line S ₁ .

In the part in which the _1st welding line S ₁ is formed, the film 1 itself which forms the packaging container 10 further becomes easy to tear, without remaining in which the film frame member 1a is isolate | separated.

Thus, as shown in FIG. 4, the film edge member 1a is peeled off in tape form, and the film 1 which forms the packaging container 10 tears.

As the film frame member 1a is pulled off in a tape shape, the tearing of the film 1 enlarges.

Using this open tear as a pod, the film 1 can be easily peeled from the contents.

In addition, in order to peel off the film 1 from the content in the cylindrical film package in a 1st Example, the method shown in FIG. 5 is also effective.

In this method, first, the film rim member 1a is shared from the cut portion 3 by a finger.

When the part indicated by (D) of the film rim member 1a (part positioned at the end side of the package body) is pulled off and peeled off, the film 1 constituting the packaging container 10 as described above is used as a second solvent. It is torn from the land line S ₂ and also to be torn from the first weld line S ₁ .

After pulling out and peeling off the film rim member 1a of the part of (D), when the content is inflated by pressing the part in which the clip 2 of the end part of the film package is formed, it expands the content, and FIG. As shown, the torn portions of the film 1 enlarge.

The torn part of the film 1 at this time is a pod, and the film 1 is easily peeled off from the contents.

4 and 5 show only one example of the opening method of the film in the cylindrical film package of the first embodiment, and can be opened by another method.

Even opening in any way, tear up for chakseon (S _2), an intermittent part (ℓ) film frame member (1a) from the cutting unit (3) formed on, and by pulling the film frame member (1a), At this time, the torn portions of the film 1 generated as pods can be easily peeled off from the contents.

6 and 7 show a second embodiment of the present invention, and FIG. 6 is a partial front view showing a cylindrical film package, and FIG. 7 is a partial front view showing its open state.

In this embodiment, the intermittent portion (l) of the second chakseon (S ₂₎ for the in a film frame member (1a), is not a shown in FIG. 1 by reference numeral 3, the cut (notch) is formed .

Further, the film frame member (1a) is one which becomes bent folded back two and chakseon for the first (S ₁₎ and a place where the second is chakseon (S ₂₎ is formed for, such as is shown in the first FIG. Same as the first embodiment.

Thus, even if the cutout part 3 is not formed in the film frame member 1a, the operation | work which peels the film 1 from the contents is easy.

As an example of the method, the film rim member 1a is held by a finger at the intermittent portion ℓ of the _second welding line S ₂ , and the film rim member 1a is held as shown in FIG. 7. Pull it off

As a result, the film 1 is torn from the portion of the welding line S ₂ , and the film 1 is easily torn from the portion of the _first welding line S ₁ , and the contents are exposed.

Even if the structure does not form the cut portion 3 in this way, it is possible to easily peel off the film (1) from the contents by pulling off the film frame member (1a).

8 is a third embodiment of the present invention. This figure is a partial cross section of the packaging container of a cylindrical film package.

In this third embodiment, the film frame member 1a and 1b of the film 1 forming the package box 10 overlap each other, and the film frame member protrudes to the outer side of the package box 10. (1a) is folded back outward from the broken line (4).

Then, the film rim member 1a, which is folded and overlapped with each other, and the film 1 forming the packaging container 10 are together due to the first welding line S ₁ and the second welding line S ₂ . It is welded.

That is, in the two places of the first chakseon (S ₁₎ and chakseon (S ₂₎ for the second for the, so that the three sheets of film is welded.

As shown in FIG. 1, in the first embodiment, two films are welded on the first welding line S ₁ , but the welding length of the film on the first welding line S ₁ is 1st. The embodiment differs from the third embodiment.

Also in this third embodiment, an intermittent portion (such as (l in FIG. 1)) is formed in the _second welding line S ₂ , and in some cases, an edge of the film at the intermittent portion. A member cut is formed.

In the third embodiment, it is the deposition thickness of the for chakseon (S ₁₎ thicker because the three sheets of film welded together according to claim 1 chakseon (S ₁₎ for a, the a in the first embodiment The welding strength is higher than the welding line of 1.

Also in this embodiment, as shown in FIG. 4, FIG. 5, or FIG. 7 by putting a finger from the intermittent part of the _2nd welding line S2, and pulling out the film rim member 1a, a packaging container is shown. The film 1 which comprises (10) can be easily torn off.

In particular, in this third embodiment, in both the first welding line S ₁ and the second welding line S ₂ , the film rim member 1a in which two sheets are stacked together is one film on the packaging side. It is welded together with (1).

Thus, when peeled off by pulling the film frame member (1a), in the for of both chakseon (S ₁₎ and (S _2), the two sheets superposed film frame member (1a) than the one sheet of film (1) side of the packaging tongjjok It becomes easy to tear.

Accordingly, when pulling the strip film frame member (1a), a tear is easily to occur in the film (1) In the same manner as part of chakseon (S ₂₎ for in chakseon (S ₁₎ for the parts.

Therefore, the second film (1) of the portion to be fitted to one for chakseon (S ₁₎ and (S _2), with the film frame member (1a) is being torn off easily by a tape state.

That is, the film 1 is more likely to be torn at the portion of the _first welding line S ₁ than in the first embodiment shown in FIG.

As described above, according to the present invention, the film rim member of both sides of the film forming the cylindrical packaging tube is overlapped and welded by the first welding line, and the outer film rim member is folded again and folded and folded. Two overlapping film frame members and a film forming a packaging container are welded together by a second welding line.

In the first welding line, since it has a high strength similarly to the conventional example shown in FIG. 10, even if the film tension is increased by the voile process in the case of sausage, it becomes difficult to break a packaging container from a dent line.

In addition, since the intermittent portion is formed in the second welding line, the film can be easily peeled from the contents by inserting a finger from the intermittent portion and pulling the film frame member.
