Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package capable of immediately forming a processed rice food with laver from a package in which laver and processed rice food are separated and packaged, and in particular, the opening of the package is extremely smooth. Also, the present invention relates to a package of processed rice food that can easily form a processed rice food with seaweed, and an improvement of a packaged food product of processed rice using the package.

[0002]

2. Description of the Related Art Conventionally, as a package for processed rice food as described above, for example, as shown in FIG. 11, an outer film having a cut tape 35 for opening at a substantially central portion 33 in the width direction is provided.
31 and a pair of interior films that are heat-sealed integrally with the peripheral portion 32 of the outer film 31 and are polymerized so as to be separable at the position of the cut tape 35, and a laver 34 is stored between the two films. And a film for storing rice for triangular onigiri with the film, and symmetrically positioned with respect to the cut tape 35 at seal portions at both ends of one end (upper side) of the two films. A pair of cutouts 42, 42 are provided in which a portion surrounded by the oblique line 40 and the parallel line 41 is cutout.

[0003] That is, the packaging film has a pair of notches 42, 42 provided symmetrically with respect to the cut tape 35.

Accordingly, as shown in FIG. 12, rice for wrapping a triangular rice ball is wrapped in the film, and then the outer film 31 is wrapped.
Notches 42, 42 at both ends of both films, even if label 39 is applied over the overlapped portion of the film at both ends of one end (upper side) to seal the package. Thereby, polymerization at both ends of the film can be suppressed within a small range.

Therefore, even when the package is opened via the cut tape 35, the film can be prevented from hindering the opening by the cut tape 35 as much as possible.

[0006]

However, in the case where the rice for triangular rice balls is wrapped with the packaging film having the above structure, the label 39 is stuck to the overlapping portion of the film on both sides. In addition, both ends of the film, which are polymerized and fixed to the outer film 31 in the cross state in the movement-prevented state by the label 39, not only obstruct the path of the cut tape 35 but also make the tearing of the outer film 31 extremely difficult. The problem had arisen.

[0007] The present invention has been made in view of the above-mentioned conventional problems. In a package that can be packaged by separating seaweed and processed rice food, for example, labels are provided at both ends of the film. A package of cooked rice food and a cooked rice food product using the package, in which the unpacking (opening) of the package is extremely smooth and easy even when attached to the polymerization site side. It is an object to provide a packaging device.

[0008]

The present invention has the following technical means to solve the above-mentioned problems.

That is, the package of processed rice food according to the present invention comprises a rectangular outer film 1 whose substantially central portion 3 in the width direction can be cut into a substantially band shape by cutting means, and a substantially peripheral portion of the outer film 1. 2 and a pair of separable inner films 4 polymerized at a substantially central portion 3 in the width direction, and laver is stored between the films 1 and 4 so that the rice 1 and 4 In a package capable of packaging processed food, a substantially saw-toothed or substantially wavy cutout 12 is provided at both ends along the longitudinal direction of the films 1 and 4.

Therefore, when the package is sealed, even if the label 19 is affixed to the overlapping portion side of the film on both sides, the outer film is cut into a substantially band shape through the cutting means. The cut portion 1 is guided into the tapered cut 12a of any of the substantially saw-toothed or substantially wavy cutouts 12 provided on both side ends of the films 1 and 4.

Thereafter, the cut portions of the outer film 1 cut into a substantially strip shape guided into the tapered cuts 12a are formed by polymerization of the two films 1, 4 using the tapered cuts 12a as cleavage starting points.
Will be cut off at both ends.

At this time, since both end portions of both films 1 and 4 are fixed to the outer film 1 in a crossed state by a label 19 in a movement-preventing state, the both films 1 and 4 are cut at the time of cutting. Not only can floating at both end portions be reliably prevented, but also more reliable cutting can be performed.

Therefore, when the package is sealed as described above,
Even when the label 19 is stuck to the overlapping portion side of the film on both side ends, there is an advantage that the opening operation of the package can be performed extremely smoothly and easily.

Furthermore, a substantially saw-like or substantially wavy cutout 12 is provided.
When the outer film 1 is cut into a substantially band shape through cutting means,
The rear opening of the tapered cut 12a of the notch 12
12b can face each other.

Therefore, the outer film 1 cut into a substantially strip shape
There is an advantage that the guide to the tapered cut 12a side of the cut portion can be easily performed.

Further, when the cutting means is a plurality of cut tapes 5 provided at a distance, the outer film 1 is cleaved into a substantially strip shape with a width substantially equal to the distance between the cut tapes 5. There is an advantage that it becomes possible.

Accordingly, there is an advantage that it is possible to very easily and quickly take out the processed rice cooked food from the cleaved package with a width substantially equal to the distance between the cut tapes 5.

At least one end of each of the films 1 and 4 is provided with two heat seals 13 crossing each of the plurality of cut tapes 5 in the width direction of the films 1 and 4. In one portion of the outer film 1 located between the seals, a cut cut across the cut tape 5
An opening knob 15 formed through the opening 14 is provided.

Therefore, the opening knob 15 formed through the cut 14 can be easily and reliably raised from one portion of the outer film 1 vertically fixed through the two heat seals 13 and made to appear. Not only can be made, but also can be used as the starting point of cleavage of the package.

Therefore, by pulling the opening knob 15, the package can be torn while peeling the cut tape 5 from the outer film 1 together with the opening knob 15.

Thus, by pulling the opening knob 15, one portion of the outer film 1 can be easily and instantly split into a strip having a width substantially equal to the distance between the plurality of cut tapes 5.

Accordingly, there is an advantage that it is possible to take out the cooked rice product from the cleaved package with substantially the same width as the separation between the cut tapes 5 very easily and quickly.

Further, the packaged rice cooked food product using the packaged rice cooked food product of the present invention has a substantially rectangular outer film 1 whose substantially central portion 3 in the width direction can be cut into a substantially band shape by cutting means.
And a pair of separable inner films 4 adhered to a substantially peripheral portion 2 of the outer film 1 and superposed at a substantially central portion 3 in the width direction.
A package is formed from the first and fourth films, and the laver is stored between the two films 1 and 4 and the cooked rice food placed on the inner film 4 is wrapped by folding the package into two. An outer film 1 which can be packaged by polymerizing both side ends along the longitudinal direction, and which is cut into a substantially band-like shape via cutting means when opening the packaging tool.
The outer film 1 in which a tapered notch 12 for guiding a cutting portion of the above and dividing the both side end portions is cut through cutting means.
In the position opposed to the cutting part of the above.

Thus, according to the cooked food product for cooked rice, the outer film 1 cut into a substantially band shape through the cutting means.
The rear opening of the tapered cut 12a of the notch 12
12b can face each other.

Therefore, the outer film 1 cut into a substantially strip shape
The guide to the tapered notch 12a side of the cut portion of the film is easily smoothed, and even if the label 19 is stuck to the overlapped portion side of the film on both side edges when sealing the package, it is surely attached. In addition, there is an advantage that the opening operation of the package can be performed extremely smoothly and easily by dividing both side ends through the cut portion.

[0026]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

First, as shown in FIGS. 1 to 5, the main body A of the packaged rice cooked food product according to the present invention has a substantially rectangular outer film 1 adapted to be covered with a substantially triangular onigiri B. The inner film 4 is composed of a pair of films 4a and 4b which are heat-sealed integrally at the peripheral edge portion 2 and are superimposable and separable at a substantially central portion 3 in the width direction. This is a substantially bag-shaped package that can store the sheet laver C between the films 4.

When eating the rice balls B stored in the package having the above structure, first, the outer film 1 is cut by cutting means described later, and a pair of films 4a, 4a, By separating (separating) 4b, only the package can be removed, and the rice laver B can be easily covered with the sheet laver C.

As shown in FIG. 1, the outer film 1 has an opening cut tape 5 used as a cutting means attached to the back side of the substantially central portion 3 in the width direction.
At one end (upper side) 6 of the package body A to which the cut tape 5 is attached, an outer film 1 made of the cut tape 5 is attached.
In order to facilitate cleavage, two notches 7, 7 serving as cleavage starting points are provided along both sides of the cut tape 5.

As shown in FIGS. 2 to 4, the inner film 4 composed of the pair of films 4a and 4b is polymerized at a position overlapping the cut tape 5 at a substantially central portion 3 in the width direction. The separated portion 9 is located along the cut tape 5 so as to be separated (separable).

The heat seal is not applied to the one end 6 and the other end (lower side) 6 'where the cut tape 5 is located, and the outer film 1 is opened (cut) by the cut tape 5. Is easy.

Further, the main body A of the package is provided with the components shown in FIGS.
As shown in the figure, with respect to the substantially central portion 3 in the width direction of the outer film 1 and the inner film 4, the seal portions at both end portions on the one end (upper side) 6 side are substantially downwardly centered in the width direction. A substantially saw blade-shaped notch portion 12 cut out in a substantially arc shape so as to be separated from the portion 3 extends at a symmetrical position via the cut tape 5 with a predetermined length.

As a material of the outer film 1, for example, polypropylene or the like is used, and a display or decoration print or the like is applied to the surface as necessary.

Further, it is preferable that a directional film is used as the outer film 1. In this case, the outer film 1 is formed so that its tearing direction (stretching direction) substantially matches the longitudinal direction of the cut tape 5. There is an advantage that the tearing of the outer film 1 is extremely easy, but it goes without saying that the use of the directional film is not limited as long as the cut tape 5 is attached.

As a material of the inner film 4, the inner film 4 is interposed between the rice ball B and the laver C until it is eaten, and is pulled out between the rice ball B and the laver C when eating. Therefore, for example, it is optimal to use polyethylene or the like that is excellent in water resistance and chemical resistance and does not allow water vapor, air, etc. to pass through, but the material is not limited.

Next, the case where the onigiri B is actually packaged using the package containing the laver C will be described.

First, as shown in FIGS. 3 and 4, when the above-described substantially triangular rice ball B is wrapped,
Is placed along a substantially central portion 16 intersecting with the longitudinal direction of the inner film 4 side, and is attached to the package body A on the other end (lower side) 6 ′ side divided by the substantially central portion 16. To surround one side of the triangular rice ball B.

Next, as shown in FIG.
A substantially saw blade-shaped notch 12 is extended at a fixed length with respect to the substantially central portion 3 in the width direction 4 of each of the package bodies A at both ends on the one end (upper side) 6 side. Then, it is bent along the peripheral side surface of the triangular rice ball B to surround the other surface of the rice ball B.

Thereafter, both side edges are superposed in a crossed state so that the substantially saw-shaped notch portion 12 faces downward, and then both sides of the both ends are sealed and used for sealing and display. Label 19
, The both ends are polymerized and fixed to the surface of the outer film 1 in a state where movement is inhibited, and the packaging of the rice ball B by the package body A is completed.

Before attaching the label 19,
For example, there is an advantage that it is possible to increase the sealing performance by point-sealing (not shown) either one of the bent both end portions to the outer film 1, but it is needless to say that it is not an essential requirement. No.

Therefore, as shown in FIG. 5, when eating the wrapped triangular rice ball B, a substantially saw-shaped notch is formed at both ends of the films 1, 4 with respect to the substantially central portion 3 in the width direction. 12 is extended by a certain length.

Therefore, when the package is sealed, even if the label 19 is affixed to the overlapping portion side of the film on both sides, the label 19 is cut into a substantially band shape through the cut tape 5. The cut part of the film 1 is the film 1, 4
The guide is guided into one of the tapered cuts 12a of the substantially saw-shaped cutouts 12 provided at both side end portions.

Accordingly, the cut portions of the outer film 1 cut into a substantially strip shape guided into the tapered cut 12a are formed by polymerization of the two films 1, 4 using the tapered cut 12a as a cleavage starting point.
Will be cut off at both ends.

Since both ends of the films 1 and 4 are fixed to the outer film 1 in a crossed state by the label 19 in a state where movement is prevented, the both ends of the films 1 and 4 are cut. Not only can be reliably prevented, but also more reliable cutting (not shown) can be performed.

Therefore, even if the label 19 is stuck to the overlapping portion of the film on both sides, the opening of the package can be performed very smoothly and easily.

Further, when the substantially saw blade-shaped notch portion 12 provided with a certain length is extended in a substantially arc shape, the outer portion cut into a substantially band shape through the cut tape 5 is provided. Film 1
The rear opening 12b of the tapered notch 12a of the notch guide 12 can be directed to the side of the cut portion.

Therefore, the outer film 1 cut into a substantially strip shape
There is an advantage that the guide to the tapered cut 12a side of the cut portion can be easily performed.

In the above-described embodiment, the substantially saw blade-shaped notch portion 12 extending at a certain length is formed in a substantially arc shape, but is not necessarily limited to a substantially arc shape. Instead, for example, as shown in FIG. 6A, the whole may be formed in a substantially U-shape (depending on the positions of the left and right sides in plan view, one of the sides may be formed into a substantially U-shape). Good.

Further, as shown in FIG. 3 (b), the substantially saw blade-shaped notch portion 12 is formed in a straight line shape, and the width thereof increases from one end 6 to the other end of the package. It may be formed to be inclined in the shape of a letter.

Further, as shown in FIG. 7C, the lower end diagonal line 17 and the parallel line 18 surround the seal portions at both end portions of the one end portion in a symmetrical position with respect to the cut tape 19. A pair of cutouts 20, 20 in which parts are cutout are provided,
Moreover, a configuration may be employed in which a substantially linear saw blade-shaped notch portion 12 is extended at a fixed length on both side edges below both end portions where the notches 20, 20 are provided.

Therefore, in any of the above cases, the cut portion of the outer film 1 to be cut into a substantially strip shape is formed by any of the tapered cuts of the substantially saw blade-shaped cutouts 12 provided at both end portions. 12
a, and consequently the tapered cut 12
It is possible to cut each of the two end portions of both films 1 and 4 formed by polymerization using a as a cleavage starting point.

In the above embodiment, one cutting tape 5 is used as the cutting means. For example, as shown in FIG. A configuration may be employed in which a plurality of cut tapes 5 and 5 are adhered to each other with a fixed separation dimension. In this case, the outer film has a width substantially equal to the separation dimension between the cut tapes 5 and 5. There is an advantage that it becomes possible to cleave 1 in a substantially strip shape.

Accordingly, the outer film 1 can be cut into a wide band with a width substantially equal to the distance between the cut tapes 5 by increasing the distance between the cut tapes 5, so that the cooked rice from the cut package can be processed. There is an advantage that food can be taken out very easily and quickly.

Further, when the cutting means has a plurality of cut tapes 5 and 5 as described above, the two films 1 and 4 are used.
At least at one end, two heat seals 13 intersecting with each of the plurality of cut tapes 5 are provided in the width direction of the films 1 and 4, that is, the heat-sealed peripheral portions 2 of the films 1 and 4.
The cut tape 5 is provided at one portion of the outer film 1 provided between the two heat seals.
Opening knob through cut 14 cut across
15 may be formed.

Therefore, the opening knob 15 formed through the cut 14 can be easily and surely raised from one portion of the outer film 1 vertically fixed through the two heat seals 13 so as to appear. In addition to this, there is an advantage that it can be used as the starting point of the cleavage of the package.

Therefore, by pulling the opening knob 15, the package can be torn while peeling the cut tape 5 from the outer film 1 together with the opening knob 15.

Thus, by pulling the opening knob 15, as shown in FIG. 8, one portion of the outer film 1 can be easily and instantly formed into a strip having a width substantially equal to the separation between the plurality of cut tapes 5. In addition to the advantage that the triangular rice ball B can be easily and quickly taken out from the package that has been cleaved at a width substantially equal to the separation dimension between the cut tapes 5, there is an advantage.

Further, as described above, two heat seals 13 may be provided at both ends of the films 1 and 4 so as to reach the heat-sealed peripheral portions 2 of the films 1 and 4, When a single heat seal 13 is provided at both ends of the films 1 and 4 as well as the heat seal 13, it is possible to seal the laver C stored between the films 1 and 4. Until the package is opened, there is an advantage that the seaweed C can be prevented from getting damp and the freshness can be prolonged.

When a plurality of cut tapes 5 are used as described above, for example, as shown in FIGS. 9 and 10, the distance between the respective cut tapes 5 (arrow E) toward the center of the package. Is formed so as to gradually expand from the interval (arrow F) between the cut tapes 5 at one end and the other end of the films 1 and 4, it is extremely easy to take out the triangular rice ball B from the cleaved package. There are advantages that can be done.

In other words, when the cut tape 5 is used, the lower oblique line 17 and the lower diagonal line 17 are positioned symmetrically with respect to the plurality of cut tapes 19 at both end portions of both ends of the films 1 and 4. A pair of cutouts 20, 20 are provided in which the portion surrounded by the parallel line 18 is cutout, and a substantially linear saw blade is formed on both side edges below both ends where the cutouts 20, 20 are provided. It is preferable to use a package in which the notch 12 is provided with a fixed length in order to secure a larger cleavage area.

Further, in the above embodiment, the outer film 1 uses the cut tape 5 as a cutting means capable of cutting the substantially central portion 3 in the width direction into a substantially strip shape, but the cut tape 5 is not necessarily required. .

Therefore, for example, a belt-like sheet member having a constant width and a constant length capable of cutting the outer film 1 into a substantially band shape may be attached to the substantially central portion 3 in the width direction of the outer film 1.

Accordingly, even in this case, there is an advantage that the substantially central portion 3 in the width direction of the outer film 1 can be cut into a substantially strip shape with a substantially width dimension of the sheet by pulling the sheet. It goes without saying that the specific structure, material, shape and number of the cutting means are not limited.

In addition, a substantially saw blade-shaped notch 12 is provided at both ends with respect to the substantially central portion 3 in the width direction of the films 1 and 4 at a fixed length. One portion of the outer film 1, which is cut into a substantially strip shape,
As long as each of the two end portions of each side 4 can be cutably guided, the substantially saw-shaped notch 12 does not necessarily have to have the tapered cut 12a. For example, the notch 12 has a substantially wavy shape. It may be provided.

In the case where the substantially saw-shaped notch portions 12 are extended by juxtaposition such as a substantially equilateral triangular shape or a substantially isosceles triangular shape, the presence or absence of the tapered cut 12a is not limited. No, but one part of outer film 1
Preferably, a tapered cut 12a is provided to guide each of the two side ends of the 4 so as to be cuttable.

Thus, the processed cooked rice food placed on the inner film 4 in the package of the cooked rice food according to the above embodiment is
According to the cooked rice food packaging device in which the package is wrapped by folding and the both ends along the longitudinal direction of the package are polymerized and packaged, the cut portion side of the outer film 1 cut into a substantially band shape. In addition, the rear opening 12b of the tapered cut 12a of the notch 12 can be opposed.

Therefore, the outer film 1 cut into a substantially strip shape
The guide to the tapered notch 12a side of the cut portion of the film is easily smoothed, and even if the label 19 is stuck to the overlapped portion side of the film on both side edges when sealing the package, it is surely attached. In addition, there is an advantage that the opening operation of the package can be performed extremely smoothly and easily by dividing both side ends through the cut portion.

The specific configuration of each part of the present invention can be freely changed in design within the range intended by the present invention.

[0069]

According to the package of the processed rice food according to the present invention, a substantially saw-toothed or substantially wavy cutout is provided at both ends of the both films with respect to the substantially central portion in the width direction. It is an extension.

Accordingly, the cut portion of the outer film cut into a substantially band shape by the cutting means is either the substantially saw blade-shaped or the notched portion provided in the both ends of the both films. The cut portion of the outer film guided into the tapered cut, and then guided into the tapered cut, uses the tapered cut as a starting point of cleavage, and cuts both side edges of both films formed by polymerization.

Accordingly, when the package is sealed, even if the label is stuck on the overlapping portion of the film on both sides, the opening (opening) of the package can be performed extremely smoothly. It has the special effect of being able to provide a package of cooked cooked rice food that can be easily made and a packaged rice cooked food product using the package.
