However, just because a product is stored in a container does not mean that the product does not move at all. Depending on the content and quantity of the product, the product moves when the film or container is moved during transportation, which impairs the aesthetics of the package. There is a problem.
For example, as shown in FIG. 4 of Patent Document 1, the film covering the upper surface of the container and the product are in close contact, and the product stored in the container is a lunch box made from rice or side dishes, a raw vegetable salad, a potato In the case of a salad or the like, when the product moves, adhesion marks that are generated due to the product slipping remain on the inner surface of the film that is in close contact with the product. Even if a certain amount of gap is provided between the film covering the upper surface of the container and the product, it is inevitable that the product will come into contact with the inner surface of the film when the product moves, and only the adhesion mark of the product remains on the film. On the other hand, the aesthetics of the package will be damaged.

  This invention is made | formed in view of the said situation, and it aims at maintaining the beauty | look of the package in the package formed by packaging a container with a film.

  The packaging body of the present invention is a packaging body in which a container having an opening at the top is pillow-wrapped with an exterior film, and the container is on the front and back side surfaces in the flow direction in which the exterior film is supplied during pillow packaging. It has the notch part which opposes, The inner film longer than the distance of the said notch part is spanned across the notch part inside the exterior film, It is characterized by the above-mentioned.

  According to the package of the present invention, the adhesion mark of the contents stored in the container hardly remains on the film, and the aesthetic appearance of the package can be maintained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this embodiment is for demonstrating the summary of this invention, and this invention is not limited to this.
Moreover, in FIGS. 1-4, the same code | symbol is attached | subjected to the same component and the description may be abbreviate | omitted.

FIG. 1 is a perspective view of an embodiment of a package according to the present invention. As shown in FIG. 1, the package 10 of the present invention is such that a container 13 in which an inner film 12 is stretched over a notch 14 a and a notch 14 b is pillow-wrapped with an exterior film 11. .
Here, pillow packaging refers to the packaging form described below.
The strip-shaped exterior film is heat-sealed by combining two long sides along the direction in which the strip-shaped exterior film is guided (hereinafter referred to as “flow direction”) to form a tubular shape. Next, the article to be packaged is supplied from the opening of the tubular exterior film, and the openings at both ends of the tubular exterior film are closed.

A container 13 used in the package 10 of the present invention is separately shown in FIG.
The shape of the container 13 is not particularly limited as long as it has an opening 17 in the upper part.
For example, as the bottom surface 18, various shapes such as a circle, an ellipse, a square, a rectangle, a hexagon, and a polygon can be considered. Furthermore, the shape of the opening 17 may be the same as or different from the bottom surface 18.
Moreover, the height of the container 13 should just select an appropriate height with the content accommodated in an inside, and is not specifically limited.

  Examples of the material of the container 13 include resins such as polyethylene, polypropylene, polyester, and polystyrene, and paper.

As shown in FIG. 3, the container 13 includes a notch portion 14 a and a notch portion 14 b that are opposed to each other on the front and rear side surfaces in the flow direction through which the exterior film 11 is guided during pillow packaging.
As shown in FIG. 1, the cutout portion 14a and the cutout portion 14b are provided for the purpose of bridging the inner film 12.
The length W of the notch 14a and the notch 14b in a direction substantially perpendicular to the flow direction (hereinafter referred to as “width direction”) shown in FIG. 3 is not more than the length of the container 13 in the width direction. There is no particular limitation as long as it has a width that allows the inner film to be bridged. However, when the length W in the width direction of the notch portion 14a and the notch portion 14b is longer than the length in the width direction of the inner film, it is preferable that the movement in the width direction of the inner film is not easily restricted.

In the package of the present invention, when the depth D of the cutout portion 14a and the cutout portion 14b is long, as shown in the cross-sectional view of the package of the present invention in FIG. Tend to come into contact. However, if the depth D is too long, the contents 15 cannot be stored inside the container 13, and the contents 15 overflow from the container 13. Therefore, it is preferable to determine the depth D of the cutout portion 14a and the cutout portion 14b in consideration of the storage amount of the content 15 and the degree of contact between the content 15 and the inner film 12.
In addition, there is no restriction | limiting in particular in the number of the notch parts which are installed in the container 13, and a notch part can be installed according to arrangement | positioning of the content and the number of inner films.

  Examples of the exterior film 11 include a polyester film, a polypropylene film, and a nylon film. Examples of the resin forming the polyester film include PET. Examples of the resin forming the polypropylene film include biaxially oriented polypropylene (OPP). Furthermore, you may provide gas barrier property to the package 10 using the film which has gas barrier property for the exterior film 11, as needed. As the film having gas barrier properties, a film made of polyvinyl alcohol resin (PVA), a film made of ethylene / vinyl alcohol copolymer (EVOH), a film made of polyvinylidene chloride (PVDC), and these films were included. A multilayer structure film etc. are mentioned. In addition, a vapor deposition film obtained by depositing aluminum, silica or the like on an unstretched polypropylene film, an aluminum foil laminate film, or the like can also be used. Further, the exterior film 11 may be a film having a multilayer structure in which a plurality of the above-described resins are multilayered.

The length in the flow direction and the length in the width direction of the exterior film 11 used for one container may be any length as long as the container 13 packaged with the exterior film 11 can be tightly pillow-wrapped so as not to move within the package. Although not particularly limited, it is particularly preferable that the outer film 11 covering the opening portion of the container 13 has such a length that it can be stretched so as not to bend even if an object is stacked thereon.
Moreover, although the thickness of the exterior film 11 is not specifically limited, 15-40 micrometers is preferable.

The inner film 12 is preferably supplied by being stacked inside the exterior film in the pillow packaging described above.
The inner film 12 is bridged so as to pass through the notch portion 14a and the notch portion 14b of the container, so that the inner film 12 comes into contact with the contents 15 stored in the container and maintains the aesthetic appearance of the package of the present invention. The purpose is that.

Examples of the inner film 12 include a transparent film such as a polypropylene film.
In addition, although the thickness of the inner film 12 is not specifically limited, 15-40 micrometers is preferable.

The length in the width direction of the inner film 12 is equal to or less than the length W in the width direction of the cutout portion 14a and the cutout portion 14b, and is a length that achieves the object of the present invention to maintain the aesthetic appearance of the package. If there is no restriction in particular.
When the length in the width direction of the inner film 12 exceeds the length W in the width direction of the cutout portion 14a and the cutout portion 14b, the inner film passes through the cutout portion 14a and the cutout portion 14b of the container. In other words, it cannot be put over and the aesthetics of the package cannot be maintained.

The length of the inner film 12 used in one container in the flow direction is longer than the distance between the notch portion 14a and the notch portion 14b facing each other through the inner film 12.
As shown in FIG. 1, by making the length of the flow direction of the inner film 12 longer than the linear distance between the notch portion 14a and the notch portion 14b facing each other, the inner film 12 is notched with the notch portion 14a. It will be in the state loosened between the parts 14b.
In this invention, the beauty | look of the package 10 can be maintained by loosening the inner film 12 in this way.

Further, the length of the inner film 12 used in one container in the flow direction is preferably the same as the length of the outer film 11 used in one container in the flow direction. The container 13 includes a notch portion 14a and a notch portion 14b.
When a container without a notch is used, if the lengths in the flow direction of the inner film and the outer film are made equal, the inner film only covers the outside of the container in the same manner as the outer film. However, the container 13 according to the package 10 of the present invention includes a notch portion 14 a and a notch portion 14 b for bridging the inner film 12. Therefore, when the length in the flow direction of the inner film 12 and the length in the flow direction of the exterior film 11 are made equal, the length is approximately equal to the total length of the depths D of the cutout portion 14a and the cutout portion 14b. Therefore, the length of the inner film can be increased and the inner film 12 can be loosened.
Such a package of the present invention can be manufactured by supplying the inner film 11 and the outer film 12 at the same time, which is preferable in manufacturing.

As described above, the packaging body 10 of the present invention has the container 13 provided with the notch 14a and the notch 14b facing each other and the inner film 12 passing through the notch inside the exterior film 11. Yes.
Then, as described above, the length of the inner film 12 is longer than the distance between the notch portion 14a and the notch portion 14b, and the inner film 12 is loosened, so that as shown in FIG. When the content 15 is stored, the content 15 covered by the inner film 12 and the inner film 12 can be brought into contact with each other.
At this time, the inner film 12 is a portion where the contents 15 and the inner film 12 are not in contact with each other by the distance (A) from the contact end a between the inner film 12 and the contents 15 to the container notch lower end portion 13a. Occurs. And in this non-contact part, the length of the inner film 12 has a space. Further, the inner film 12 has a portion where the contents 15 and the inner film 12 are not in contact with each other by a distance (B) from the contact end b between the inner film 12 and the contents 15 to the container notch lower end portion 13b. Arise. And in this non-contact part, the length of the inner film 12 has a space.
Therefore, for example, when the contents 15 approach the container notch lower end portion 13a, the clearance (A) can be reduced and the distance (B) can be increased by these clearances. That is, the contact surface of the inner film 12 and the content 15 can be moved toward the container notch lower end portion 13 a in accordance with the movement of the content 15. Moreover, when the content 15 approaches the container notch lower end part 13b, distance (A) can be enlarged and distance (B) can be made small by these clearances. That is, the contact surface of the inner film 12 and the content 15 can be moved toward the container notch lower end portion 13 b in accordance with the movement of the content 15.
In such a package 10 of the present invention, the contact surface between the inner film 12 and the content 15 is fixed regardless of the movement of the content 15, and the content is difficult to adhere to other than the contact surface. Therefore, it is difficult for the contents to adhere to the contact surface of the film.
Moreover, since the content 15 is covered with the inner film 12, even if the content is moved, it is difficult for the content to adhere to the exterior film.
That is, the packaging body 10 of the present invention can maintain the aesthetic appearance of the packaging body 10 even if the contents 15 are moved by holding or moving the exterior film 11.
Furthermore, in the present invention, since the package body can be manufactured by making the exterior film 11 and the inner film 12 into the same length, the packaging with the exterior film 11 can be made tighter, and the opening of the container 13 can be made. It is possible to give the covering film 11 to be covered a tension that does not bend even if an object is stacked thereon.

Next, an example of a method for manufacturing the package 10 according to the embodiment of the present invention will be described.
In FIG. 4, the schematic diagram which is an example of the shaping | molding apparatus of the package of this invention is shown.
As shown in FIG. 4, the strip-shaped outer film 11 and the strip-shaped inner film 12 are respectively guided to the roller 43a by the outer-film roll 41 and the inner-film roll 42. Next, the guided outer film 11 and inner film 12 are overlapped by a roller 43a and guided to the bag making device 44 through the rollers 43b and 43c. Thereafter, the two long sides of the strip-shaped exterior film 11 along the flow direction are put together and heat-sealed by the heat sealer 45 to form a heat seal portion 16c to form a cylinder.
Moreover, the container 13 which is an article to be packaged is supplied from the openings on the rear side in the flow direction among the openings on both ends of the cylindrical outer film 11. At this time, as shown in FIG. 1 later, the container 13 is supplied to a position where the inner film 12 can be bridged over the notch 14a and the notch 14b of the container 13.
Thus, after covering the container 13 with the cylindrical exterior film 11, the front and rear in the flow direction of the container 13 are heat-sealed with the heat sealer 46 to form the heat seal portions 16a and 16b. The package 10 is obtained.
In this manufacturing method, since the exterior film 11 and the inner film 12 are guided simultaneously, the lengths in the flow direction are the same. However, as shown in FIG. 1, the container is provided with a notch portion 14a and a notch portion 14b, and the inner film 12 is loosened by being spanned over the notch portion 14a and the notch portion 14b. It becomes a state. When the product is stored in such a package, the inner film 11 and the product are in contact with each other, and the contact surface is in a state of being difficult to move as described above, so that the beauty of the package 10 can be maintained. Become.

It is a perspective view which shows the state which stored the content in the package of the example of 1 embodiment of this invention. It is sectional drawing which cut | disconnected the package of the example of embodiment of FIG. It is a perspective view of the container inside the package of the embodiment example of FIG. It is a schematic diagram which shows an example of the shaping | molding apparatus of the package of this invention.
