Description

The present invention relates to a carton for accommodating an article and a wrap film product using the carton.

Wrappers such as plastic wrap, aluminum foil, and parchment paper are usually housed in a rectangular parallelepiped carton in a rolled state. This carton has a rectangular parallelepiped container body having an open upper surface for accommodating articles, and a lid portion covering the opening on the upper surface of the container body. Before opening the carton, the lid is sealed with a strip-shaped opening piece along the longitudinal direction located on the front surface of the container body with the opening on the upper surface of the container body closed. Then, at the start of use, the carton is opened by cutting off the opened piece.

The above-mentioned carton needs to have an opening piece that seals the lid sufficiently adhered to the container body so that the carton will not be opened without permission at the distribution stage until it reaches the consumer. On the other hand, it is required that the opened piece can be easily cut off at the start of use so that the opened piece can be easily opened. As such a carton, for example, in Patent Document 1, when at least one of the adhesive portions for adhering the opening piece and the container body has a curved line at the rear end, the width at the rear end is the diameter of the circle of curvature at the rear end. As a result, a carton that has sufficient adhesion at the distribution stage and suppresses adhesive residue after opening is disclosed.

Japanese Unexamined Patent Publication No. 2014-12060

By the way, since the opened piece is cut off at the time of opening, it is suitable as a part for providing an application ticket, a bell mark (registered trademark), and the like. When an application ticket, a bell mark, etc. are provided on the opened piece, it is desirable that the section including these can be easily cut off from the opened piece. On the other hand, it is necessary to ensure the adhesive stability of the opened piece so that the unopened state of the carton at the distribution stage is maintained even when the application ticket, the bell mark, and the like are provided.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a carton in which an open piece provided with a cuttable section and a container body have stable adhesiveness.

In order to solve the above problems, the carton according to the present invention is connected to a container body having an open top surface for accommodating articles, a lid portion covering the opening of the container body, and the lid portion in an unopened state. However, it is provided with an opening piece that is adhered to the front plate of the container body and is separated from the lid portion at the time of opening, and the opening pieces are provided in a row along the separation direction. The portion is adhered to the front plate, and the opening piece is provided with a section that can be cut off from the opening piece by a cut line provided in the opening piece in a portion where the adhesive portion does not exist. , The section has a structure provided on the center side of the adhesive portion located at the end of the row.

According to the above configuration, before use, the unopened state of the carton is maintained because the opened piece connected to the lid portion is adhered to the front plate of the container body. The opened piece is provided with a section that can be cut off by a cut line, and can be used by cutting from the opened piece. The cuttable section is provided in a portion where the adhesive portion does not exist. Therefore, it is possible to prevent the section from being cut internally due to cutting in the middle of separating the opened piece, which may occur due to the presence of the adhesive portion. Further, since the section is provided on the central side of the adhesive portions located at the ends of the plurality of adhesive portions existing in a row, the adhesive portion at the end can be brought closer to the end of the opened piece. .. As a result, the adhesive stability of the opened piece is sufficiently ensured, and unintended opening of the carton can be prevented more reliably.

Further, in the carton according to the present invention, it is preferable that a cut line is provided between the opening piece and the lid portion, and the cut line intersects the cut line.

According to the above configuration, the end of the cut line extends to the end of the separated opening piece. Therefore, the cuttable section can be more easily cut from the opened piece.

Further, in the carton according to the present invention, the distance between the adhesive portion located at the rearmost position in the opening direction of the opening piece and the rear end portion of the opening piece in the separation direction is along the separation direction of the opening piece. It is preferably 6% or less of the length of the side.

According to the above configuration, since the adhesive portion located at one end is located closer to the end portion of the opened piece, the adhesive stability of the opened piece is further improved.

Further, in the carton according to the present invention, the area of the adhesive portion located at the end of the row is preferably 30% or more larger than the area of the adhesive portion other than the adhesive portion located at the end of the row.

According to the above configuration, the size of the adhesive portion located at one end is larger, so that the adhesive stability of the opened piece is more excellent.

According to the above configuration, the adhesive stability of the opened piece becomes more excellent.

Further, a wrap film product in which the article is a wrap film wound body and the article is housed in the carton is also included in the category of the present invention.

According to the carton of the present invention, even if the opened piece is provided with a cut-out section, the adhesiveness between the opened piece and the front plate of the container body can be stabilized.

It is a perspective view which shows an example of the carton which concerns on this embodiment, and shows the sealed state. It is a figure which shows an example of an opening piece, (a) shows the form which the cut line and the cut line do not intersect, and (b) shows the form which intersects.

Hereinafter, one embodiment of the present invention will be described in detail, but the present invention is not construed as being limited to these descriptions. The embodiments may be variously modified as long as the effects of the present invention are exhibited.

FIG. 1 is a perspective view showing one aspect of the carton according to the present embodiment, and shows the carton in a sealed state. As shown in FIG. 1, the carton 1 according to the present embodiment includes a container body 10 having an open upper surface for accommodating articles, a lid portion 11 covering the open upper surface of the container body 10, and a front plate 13 of the lid portion. It is provided with an opening piece 14 which is connected to. A cutting line 19 for separating the front plate 13 of the lid portion 11 and the opening piece 14 is formed. Before opening, the opening piece 14 is adhered to the front plate of the container body 10. The carton 1 can be opened by peeling the opening piece 14 from the front plate of the container body 10 and separating it from the lid portion 11. Before opening the carton 1, the front plate of the container body 10 is covered with the front plate 13 of the lid 11 and the opening piece 14, so that the front plate does not appear in the appearance. The opening piece 14 is provided with a cutting section 16.

[Opening piece]
The opening piece 14 is a portion connected to the front plate 13 of the lid portion 11 in order to fix the lid portion 11 before opening the carton 1. Since the opening piece 14 connected to the front plate 13 of the lid 11 is adhered to the front plate of the container body 10, the lid 11 is fixed so as not to open. The opening piece 14 is placed in a container from one end 18 (b) of the opening piece 14 to the other end 18 (a) (hereinafter, this direction is referred to as a disconnection direction), which corresponds to the short side of the opening piece 14. By peeling it off from the main body 10 and separating it from the lid portion 11, the lid portion 11 is released and the carton 1 can be opened.

A cut line 19 is formed between the front plate 13 of the lid portion 11 and the opening piece 14. Thereby, the opening piece 14 can be easily separated from the lid portion 11. The details of the cut line 19 will be described later.

The opening piece 14 is adhered to the front plate of the container body 10 via a plurality of adhesive portions 15. Here, the adhesion between the opening piece 14 and the front plate of the container body 10 will be described. On the surface of the opening piece 14 facing the front plate of the container body 10 (hereinafter, also referred to as the back surface of the opening piece 14), an adhesive is applied in a strip shape along the separation direction (direction of arrow A in FIG. 1). It has been applied. On the other hand, the front plate of the container body 10 is coated with a transparent release varnish for preventing adhesion in a region other than the portion to be the adhesive portion 15. After applying the adhesive, the opening piece 14 is superposed on the front plate of the container body 10 at a predetermined position and pressed with a predetermined pressure. As a result, the opening piece 14 and the front plate of the container body 10 are not adhered to each other in the portion where the release varnish is applied, and the opening piece 14 and the container are formed in the adhesive portion 15 where the release varnish is not applied. The front plate of the main body 10 will be adhered. The plurality of adhesive portions 15 are provided in a row. The details of the adhesive portion 15 will be described later.

(Cut section)
The opening piece 14 is provided with a cutting section 16 for cutting and using. Cutting and using is intended to use the cut part as an application ticket or as a bell mark.

In order to facilitate cutting of the cutting section 16, a cut line 17 is provided at a portion of the opening piece 14 that is a side of the cutting section 16 in the direction intersecting the cutting direction A. In other words, the cutout section 16 is defined by the two cut lines 17. In the present embodiment, the cut line 17 extends in a direction perpendicular to the cutting direction A.

The cut-out section 16 is closer to the center of the container body 10 than the adhesive portion 15 (a) located at one end of the row of the adhesive portions 15 and is the container body rather than the adhesive portion 15 (b) located at the other end. It is provided on the center side of 10. By providing the cut-out section 16 on the center side of the container body 10 with respect to the adhesive portion 15 (a) and the adhesive portion 15 (b) at the ends of the row, the cut-out section 16 is provided on the adhesive portion 15 (a) or the adhesive portion 15. The position where the adhesive portion 15 (a) and the adhesive portion 15 (b) are closer to the end portion 18 (a) or the end portion 18 (b) of the opening piece 14 than in the case where the adhesive portion 15 (a) and the adhesive portion 15 (b) are provided on the outer side of the container body 10 than in (b). Can be provided in. Therefore, the adhesive stability between the opened piece 14 and the front plate of the container body 10 before opening can be more sufficiently ensured. In the present specification, the state in which the adhesive stability is ensured means that the opening piece 14 does not float from the front plate of the container body 10 when the front plate of the container body 10 and the opening piece 14 are adhered to each other. It is intended for a condition and a condition where the degree of floating is very small. If the adhesive stability is insufficient, a part of other adjacent cartons or the like is likely to be caught in the gap between the front plate of the container body 10 and the opening piece 14, so it is intended at the distribution stage before the start of use. There is a risk that the lid portion 11 will open. If the adhesive stability is sufficient, it is possible to prevent the lid portion 11 from being caught and the lid portion 11 from being opened at the distribution stage before the start of use.

The cut-out section 16 is provided in the opened piece 14 at a place where the adhesive portion 15 is not provided. When the opening piece 14 is adhered to the container body 10 by a plurality of adhesive portions 15 separated from each other, if the cutting section 16 exists at the place where the adhesive portion 15 is provided, the opening piece 14 is attached to the container body. When peeling from the front plate of 10, the opening piece 14 may be cut at the portion where the adhesive portion 15 is provided. However, in the present embodiment, since the cut-out section 16 is provided in a place where the adhesive portion 15 is not provided, the adhesive portion 15 does not exist on the back surface of the cut-out section 16 in the opened piece 14. Therefore, it is possible to prevent the opening piece 14 from being cut in the middle of the cutting section 16 at the time of opening. Further, since a part of the adhesive portion 15 after opening does not remain in the cut-out section 16 after cutting, the appearance is not impaired.

The width L3 of the cut-out section 16 is not particularly limited as long as it is equal to or less than the distance between the adjacent adhesive portions 15, but for example, when the length of the long side of the container body 10 is 220 to 320 mm, the width L3 is It can be 10 to 30 mm and even 15 to 25 mm. The width of the cutting section 16 is intended to be a length along the cutting direction A.

(Cut line)
FIG. 2 is a diagram showing a part of the opening piece 14 and the front plate 13 of the lid portion 11, and is a diagram showing the positional relationship between the cut line 17 and the cutting line 19 provided on the opening piece 14. FIG. 2A shows a form in which the cut line 17 and the cut line 19 do not intersect, and FIG. 2B shows a form in which the cut line 17 and the cut line 19 intersect. Here, the state in which the cut line 17 and the cut line 19 intersect is a state in which the cut line 17 passes through the line of the cut line 19 and extends to the front plate 13 of the lid portion 11, or the state of the cut line 17. It refers to a state in which the tip reaches the line of the cut line 19 but does not extend to the front plate 13 of the lid portion 11. Further, the line of the cut line 19 is intended to be a virtual line connecting the cut line 19 which is a notch and the portion between the adjacent cut lines 19 (the connecting portion of the cut lines 19). Therefore, the state where the cut line 17 and the cut line 19 intersect is not limited to the case where the tip of the cut line 17 is on the cut line 19 as shown in FIG. 2 (b), and the state of the cut line 17 The case where the tip is at the connecting portion of the cutting lines 19 between the adjacent cutting lines 19 is also included.

The cut line 17 preferably intersects the cut line 19 as shown in FIG. 2 (b). When the cut line 17 intersects the cut line 19, the ease of cutting is improved when the cut section 16 is cut from the opened piece 14.

In the present embodiment, the adhesive portion 15 does not exist in the region of the cutout section 16. Therefore, it is possible to cut out only the cutting section 16 without peeling off the opening piece 14. Considering this point, it is preferable that the intersection of the cut line 17 and the cut line 19 is not on the connecting portion of the cut line 19, but on the cut line 19 where the cut line is actually cut. By intersecting on the cutting line 19 instead of the connecting portion of the cutting line 19, that is, at the notch portion, the cutting section 16 can be easily cut even before the opening piece 14 is separated from the lid portion 11.

The shape of the cut line 17 is not particularly limited as long as the cut section 16 can be easily cut from the opened piece 14, and examples thereof include perforations and intermittent cuts.

Of the ends of the cut line 17, the side located opposite to the cut line 19 may or may not reach the long side of the opening piece 14. However, in terms of being able to cut out the cut-out section 16 more easily, it is preferable that the cut-out section 16 reaches the long side of the opened piece 14.

(Cut line)
As described above, a cutting line 19 for separating the opening piece 14 from the opening piece 11 is formed between the front plate 13 of the lid portion 11 and the opening piece 14. The cut line 19 in the present embodiment is a plurality of notches formed intermittently from the opening side end 18 (b) of the opening piece 14 to the opening end side end 18 (a).

When the opening piece 14 is pulled in the separating direction A at the time of opening, the adhesive portion 15 is peeled off and the connecting portion between the cutting lines 19 is broken. As a result, the lid portion 11 is not fixed to the container body 10 by the opening piece 14, and the lid portion 11 can be opened and closed.

The shape of the cut line 19 is not particularly limited, and examples thereof include perforations and intermittent notches. In the present embodiment, one straight line notch is provided intermittently. Further, the cut line 19 is not limited to the case where it consists of only one straight cut, but is a substantially T-shaped cut line having a short cut orthogonal to the cut line, or a part of the cut is broken or bent. It may be a substantially J-shaped cut line.

(Adhesive part)
As described above, the back surface of the opened piece 14 is coated with an adhesive in a band shape. Further, the front plate of the container body 10 is coated with a transparent release varnish for preventing adhesion in a region excluding a plurality of adhesive portions 15. As a result, the front plate of the container body 10 and the opening piece 14 are bonded only to the plurality of adhesive portions 15 provided on the front plate of the container body 10. A plurality of adhesive portions 15 are provided in a row along the separation direction of the opening piece 14. In this embodiment, a plurality of adhesive portions 15 are provided on the same line.

The number of the adhesive portions 15 is not particularly limited as long as the opening piece 14 does not unintentionally open before use and can be easily opened at the time of use. For example, when the length of the long side of the opened piece 14 is 220 to 320 mm, the number may be 5 to 10.

It is preferable that the size of the adhesive portion 15 is such that the opening piece 14 does not unintentionally open before use and can be easily opened at the time of use. Specifically, the diameter of the adhesive portion 15 is preferably 2 mm or more, and more preferably 3 mm or more. Further, the upper limit is preferably 10 mm or less, and more preferably 8 mm or less in terms of ease of opening and maintaining the aesthetic appearance of the opening mark. When the shape of the adhesive portion 15 is other than circular, the maximum diameter may be in the above range. The plurality of adhesive portions 15 may all have the same size, or may have different sizes from each other. For example, among the plurality of adhesive portions 15, the adhesive portion 15 (a) and the adhesive portion 15 (b) located at the end of the row may be larger than the other adhesive portions 15. For example, the areas of the adhesive portion 15 (a) and the adhesive portion 15 (b) may be 30% or more larger than the area of the other adhesive portions 15, and may be 50% or more larger. By making the size of the adhesive portion at the end of the row larger than that of the other adhesive portions, the adhesive stability can be more sufficiently ensured.

Further, it is preferable that the adhesive portion 15 (b) located at the frontmost position in the separating direction of the opening piece 14 is smaller than the adhesive portion 15 (a) located at the rearmost position. As a result, the adhesive at the start portion of the opening piece 14 to be separated becomes weaker than that on the opposite side, and the opening piece 14 can be easily peeled off.

The shape of the adhesive portion 15 is not particularly limited, and examples thereof include a circular shape, a teardrop shape, a rectangular shape, and an elliptical shape.

In the present embodiment, the distance L1 between the adhesive portion 15 (a) and the end portion 18 (a) on the rear side in the separating direction of the opening piece 14 is 6% or less of the length of the side along the separating direction of the opening piece 14. It can be, and even less than 5%. Here, the distance L1 is the distance from the end 18 (a) on the end side of the opening piece 14 to the boundary portion of the adhesive portion 15 (a) closest to the end 18 (a). As the distance L1 is smaller, the gap between the opening piece 14 and the front plate of the container body 10 is less likely to occur, so that the adhesive stability can be ensured.

In the present embodiment, the distance L2 between the adhesive portion 15 (b) and the end portion 18 (b) may be the same as the distance L1 or may be a different distance. The distance L2 is preferably longer than the distance L1 because it can be opened more easily during use. The length of the distance L2 can be 6% to 12% of the length of the side of the opening piece 14 along the cutting direction, and further can be 7% to 10%. By setting the distance L2 to this range, it is possible to secure a sufficient portion to hang a finger at the time of opening, and the carton can be easily opened. The distance L2 is the distance from the end 18 (b) on the separation start side of the opening piece 14 to the boundary portion of the adhesive portion 15 (b) closest to the end 18 (b).

〔carton〕
As shown in FIG. 1, the carton 1 in the present embodiment has a horizontally long substantially rectangular parallelepiped box shape. However, the shape of the carton 1 is not limited to this. The material of the carton 1 includes, for example, cardboard, paperboard, and the like, but is not particularly limited. The thickness of the plate material forming the carton 1 is generally preferably 0.35 to 0.80 mm from the viewpoint of ease of processing. Further, the surface of the plate material may be embossed, printed, or laminated using polyethylene or the like.

The container body 10 has a box shape and can accommodate an article (not shown) inside. The articles to be accommodated are not particularly limited, and examples thereof include aluminum foil, aluminum foil having a coating layer, wrap films such as polyvinylidene chloride film and polyethylene film, and paper sheets for cooking. Therefore, as a product using the carton 1, there is a wrap film product in which the wrap film winding body is housed in the carton 1.

As shown in FIG. 1, the lid portion 11 extends from the rear surface of the container body 10 to the front surface and covers the opening of the container body 10. The lid portion 11 is provided with a front plate 13 of the lid portion 11 that covers a part of the front plate of the container body 10. The lid portion 11 can be opened and closed after the opening piece 14 is separated.

The carton 1 may be provided with a cutting means for cutting the article to be accommodated (not shown). The cutting means is, for example, a sawtooth-shaped cutting blade, and is arranged on the back surface of the front plate 13 of the lid 11 with the cutting edge protruding from the lower end side of the front plate 13 of the lid 11. The shape of the cutting means is not particularly limited, and examples thereof include a V-shape, a linear shape, and a substantially U-shape. The material of the cutting means is not particularly limited, and is, for example, thick paper, plastic, metal, or the like.

(Example 1)
The carton was made of thick paper (UF coat, manufactured by Oji Paper Co., Ltd.), and was a substantially rectangular parallelepiped having a width of 315 mm, a depth of 44 mm, and a height of 44 mm. The opened piece in this carton is adhered to the carton body by eight adhesive portions provided along the separating direction of the opened piece. In addition, two cut lines were formed between the two adhesive portions so that the cut-out section was arranged between the second adhesive portion and the third adhesive portion from the rear in the separation direction of the opened piece. The cut line intersected the cut line that separates the front plate of the lid and the opening piece. More specifically, it intersected the cut line, that is, the portion that was not the connecting portion of the cut line.
