[Technical field to which the invention belongs]
The present invention relates to a shrink wrapping body and a shrink wrapping apparatus.
[0002]
BACKGROUND OF THE INVENTION
There is a packaging form in which the periphery of a packaging box containing a packaged object is further surrounded by a shrink film. In such a packaging form, the heat-shrinked shrink film is in close contact with the periphery of the packaging box, making it difficult to open the packaging box without damaging the shrink film.
[0003]
Therefore, by looking at the state of the shrink film, it is possible to confirm the presence or absence of fraud, falsification, foreign matter, etc. with respect to the packaged object stored in the packaging box, more specifically the packaging box. In other words, if there is no abnormality in the shrink film, the safety of the packaged item is ensured.
[0004]
In the case of the shrink package in which the packaging box is surrounded by the above-described shrink film, the safety is guaranteed, so that the consumer can purchase the product with peace of mind. On the other hand, considering the consumer's opening work after purchase, the shrink film is first cut and opened to take out the packaging box. Next, the packaged package is taken out by opening the packaging box. As described above, two opening processes are required, which is complicated.
[0005]
The present invention has been made in view of the above-described background, and the object of the present invention is to easily confirm the presence or absence of mischief such as fraud and tampering, to ensure safety, and to perform unsealing processing. An object of the present invention is to provide a shrink wrapping body and a shrink wrapping apparatus that can be easily performed.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, the shrink wrapping body according to the present invention is a shrink wrapping body in which the periphery of the packaging box body is surrounded by a shrink film, and the front surface side around the upper surface of the packaging box body and A first cut line is formed along three sides of both side edges connected to the first cut line, and the lid is formed to be openable by tearing the first cut line. A second opening for opening is provided at a predetermined position of the shrink film. A cut line is formed, and the second cut line is cut along with the opening of the lid part so that the shrink film is also opened. The upper center portion of the front surface of the packaging box body has the lid on the upper side. And a claw hook portion formed with a cut line on the other side is formed, and the second cut line is formed along the first cut line formed on the both side edges. And side edges score line elements, and to have a front cut elements chevron located outside of the claw hooking portion.
[0007]
As a more specific configuration, for example, the second cut line may be formed at a position corresponding to the formation position of the first cut line. In this case, for example, when the second cut line is projected onto the first cut line, the corresponding position may coincide with the first cut line or be located outside. Of course, even if the second cut line is located inside the first cut line, the second cut line is cut along with the opening of the lid, and both the lid (packaging box) and the shrink film are opened. It only has to be adapted.
[0008]
If it does in this way, if it energizes in the direction which opens the cover part of a packaging box body from on a shrink film, the 1st cut line and 2nd cut line which were formed in the packaging box body will be cut | disconnected. And if a cover part is pulled in the direction which pulls away from a packaging box body, a 1st cut line will be cut | disconnected further and a 2nd cut line will be further cut | disconnected with the movement of a cover part in connection with it. Thereby, a packaging box body and a shrink film are opened simultaneously. Therefore, the opening process can be easily performed.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a preferred embodiment of a shrink package according to the present invention. As shown in the drawing, in the present embodiment, the periphery of the packaging box 10 is surrounded by a heat-shrinked shrink film 20 to form a shrink package.
[0011]
And the packaging part 10 has the cover part 11 formed in the upper surface. That is, the first cut lines 12 are formed along the three opposite sides around the upper surface 10a. By tearing the first cut lines 12, the lid portion 11 is lifted upward to open the packaging box body 10. The stored packaged object can be taken out.
[0012]
Furthermore, in this embodiment, a rectangular nail hook 14 is formed at the upper central portion of the front surface 10b of the packaging box 10. The claw hook 14 is connected to the lid 11 on the upper side 14a side. In other words, no cut line is provided on the upper side 14a of the claw-hanging portion 14, which is a connecting portion between the two. A cut line is formed along the lower side 14b and the side 14c of the claw hook portion 14.
[0013]
As a result, when the nail hooking portion 14 is urged to be pushed into the inside of the packaging box body 10, the cut lines formed on the three sides around the nail hooking portion 14 are broken, and the nail hooking portion 14 becomes the packaging box body. The portion where the nail hooking portion 14 was pushed into the inside 10 becomes a rectangular opening. A finger or the like can be inserted into the packaging box 10 from the opening. Therefore, by inserting a finger into the opening, placing the finger against the back side of the lid 11 and pulling it upward, the first cut line 12 formed around the lid 11 is broken, and the lid 11 (Packaging box 10) can be opened.
[0014]
On the other hand, the shrink film 20 surrounding the packaging box body 10 forms a second cut line (perforation) 21 at a position corresponding to the lid portion 11. That is, since the shrink film 20 is in close contact with the packaging box body 10, the shrink film 20 has substantially the same shape as the outer shape of the packaging box body 10.
[0015]
And when projecting from the upper surface, the second score line 21 is located at the same position as the first score lines 12 formed on both side edges of the lid portion 11, that is, at a portion contacting the pair of side edges on the top surface of the packaging box 10. Side edge score line elements 22 are formed. Further, a front cut line element 23 connected to the front end of the both side edge cut line elements 22 is formed in a film portion facing the front surface of the packaging box 10. The front cut line element 23 is arranged in an inclined shape descending toward the intermediate position, and its lowermost position 23a is positioned below the lower end of the claw hook portion 14, and further, its front cut line The claw hook 14 is positioned in the upper region R partitioned by the element 23.
[0016]
Furthermore, as shown in an enlarged view in the figure, at the position where the direction changes, such as the lowermost position 23a of the front cut line element 23, the cut portion (the cut portion of the film) continues (in the example shown, V-shaped). In this way, the film is cut along the direction in which the score line elements are formed, and the film is prevented from being cut in different directions. Since the traveling direction of the connecting portion between the front cut line element 23 and the side edge cut line element 22 is also bent (the angle formed is other than 180 degrees), the cut portions are made continuous as in the lowermost position 23a. That is, in the bent part of the cut line, the shape of the cut part is also bent along the curve.
[0017]
In order to open the shrink wrapping body configured as described above, first, the portion of the nail hooking portion 14 is urged inward from the top of the shrink film 20. Then, the force accompanying the said urging is applied also to the front cut line element 23 of the second cut line 21 formed in the shrink film 20 existing around the claw hooking portion 14 and breaks. Therefore, the second cut line 21 near the lowermost position 23a and the perforation (first cut line 12) around the nail hook 14 are broken together, and the region R of the shrink film 20 and the nail hook 14 are separated. It is pushed into the packaging box 10.
[0018]
Next, when a finger is inserted from the portion K opened by pushing the nail hook portion 14 and the finger is pushed upward (hanged) together with the lid portion 11, the first cut line 12 is broken as shown in FIG. The upward movement of the lid 11 is allowed. And if the cover part 11 is moved upwards, the film part of the shrink film 20 which opposes the cover part 11 will also be pushed up, and the 2nd folding line 21 will also be fractured | ruptured. Thus, the shrink film 20 and the packaging box body 10 can be opened together by a single process by one opening operation.
[0019]
In the example shown in the figure, the shape of each notch portion constituting each score line element is a straight line ("-"), but the present invention is not limited to this, for example, as shown in FIG. In addition to a V-shape (see FIG. 1A), a U-shape (see FIG. 1A), a + -shape (see FIG. 1A), various shapes can be employed.
[0020]
Next, an embodiment of a shrink wrapping apparatus for manufacturing the above shrink wrapping body will be described. FIG. 4 shows an example of the overall configuration of the shrink wrapping apparatus. As shown in the figure, a supply conveyor device 31 is provided on the upstream side, and the packaging box body 10 is transported by the supply conveyor device 31 and supplied to the packaging device body 32 at the next stage at a predetermined interval. Yes.
[0021]
In addition, the packaging box body 10 supplied to this supply conveyor apparatus 31 is boxed in the previous process, and is in a state in which the first cut lines are formed at predetermined positions as described above. And it conveys so that a cover part may turn up. In addition, the supply process to the supply conveyor device 31 may be performed manually or automatically using a predetermined supply device.
[0022]
Further, the supply conveyor device 31 conveys the packaging box body at predetermined intervals throughout the device like a finger conveyor, and sequentially supplies the packaging box body 32 to the packaging device main body 32 at that interval, or independently before and after. A plurality of belt conveyors that are rotationally driven are provided, at least the carry-out side (downstream side) belt conveyor is intermittently driven, and the carry-out side belt conveyor is rotated in accordance with the operation state on the packaging device main body 32 side at predetermined intervals. Various configurations can be adopted in addition to sequentially supplying the packaging box body to the packaging apparatus main body 32 every time.
[0023]
A packaging device main body 32 is installed on the downstream side of the supply conveyor device 31. The packaging box body 10 sequentially supplied from the supply conveyor device 31 is surrounded by a shrink film, and the film polymerization end is sealed and sealed. Then, it cut | disconnects and it is made to isolate | separate into each intermediate | middle package body (The thing of the state which has not shrunk the shrink film). And the shrink tunnel 33 is arrange | positioned in the further downstream side of this packaging apparatus main body 32, and it heat-shrinks with respect to each separated intermediate | middle package (before heat processing).
[0024]
Moreover, the packaging apparatus main body 32 is provided with the original fabric roll 36 which wound up the strip | belt-shaped shrink film 35, and the shrink film 35 pulled out continuously from the original fabric roll 36 has several roller 37 (feed roller, tension roller). , Idle roller, etc.) and is guided to the bag making machine 38. When the shrink film 35 passes through the bag making machine 38, the bag is made into a cylindrical shape.
[0025]
On the other hand, the packaging box 10 is supplied into the bag making machine 38 at predetermined intervals. Thereby, the packaging box body 10 is supplied into the shrink film 35 formed in a cylindrical shape, and thereafter, the shrink film 35 and the packaging box body 10 are integrally conveyed.
[0026]
Further, although not shown in the drawing, the packaging device main body 32 is provided with a center seal device and an end seal device along a conveyance path on the downstream side of the bag making device 38, and a predetermined position of the shrink film 35 formed into a cylindrical shape. Are sealed and cut to produce individual intermediate packages. In addition, since the structure of each apparatus mentioned above is the same as that of the conventional shrink wrapping apparatus, the detailed description is abbreviate | omitted.
[0027]
Here, in this invention, the die roll cutter apparatus 40 for forming a 2nd cut line is provided on the drawer | drawing-out path | route of the strip | belt-shaped shrink film 35 from the fabric roll 36 to the bag making machine 38.
