Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package in which triangular sandwiches are tightly wrapped.

[0002]

2. Description of the Related Art Conventionally, a triangular sandwich in which contents such as meat and vegetables are sandwiched between stacked breads has been sold in a state of being wrapped with a transparent film. This sandwich is obtained by cutting the bread along a diagonal line while sandwiching the contents in a rectangular bread, and the contents are most visible on the cut surface.

As a packaging form of the sandwich, for example, as disclosed in Japanese Utility Model Publication No. 1-18525, a front surface sheet and a back surface sheet formed in a flat trapezoidal shape are welded at their base end sides and both side edges. Then, a bag-shaped one is proposed. When packaging a triangular sandwich with this packaging bag, insert the sandwich from the insertion opening provided at the position facing the base side with the base side aligned with the thickness direction of the sandwich in parallel. To do. Then, by folding the open end of each sheet to close the insertion port, and by sticking and sealing at an appropriate position by an adhesive means such as an adhesive tape, a package in which the contents can be visually recognized from the cut surface of the sandwich is obtained. can get.

[0004]

In the above-mentioned conventional packaging bag, in order to insert the sandwich through the insertion opening,
A bag is used which has an inner dimension with a margin with respect to the outer diameter dimension of the sandwich. For this reason, when the sandwich is packaged in the packaging bag, a gap is generated between the sandwich and the packaging bag (causing bluntness),
There was a drawback that the product value decreased. In addition, it is pointed out that the packaging material is wasted and the cost is increased. Further, the sandwich is usually packaged and sold in a state in which a plurality of sandwiches (two breads sandwiching contents) are stacked. That is, since the total thickness dimension varies depending on the number of stacked sandwiches, it is necessary to manufacture a packaging bag having dimensions according to each specification, and it is pointed out that inventory management becomes complicated. Furthermore, when the sandwich is inserted into a packaging bag, the contents of the sandwich may rub against the inner surface of the packaging bag and stain the bag, which may make the bag unattractive and reduce the commercial value.

As a means for coping with the above-mentioned various problems, there is the invention "sandwich package" (Japanese Patent Application Laid-Open No. 6-24466) according to the applicant's earlier application. The package according to the present invention wraps a film in a thickness direction in a triangular sandwich, and folds the film along the inclined surface of the sandwich. Therefore, even if the thickness of the sandwich changes, the film There is no need to change the width dimension of the sandwich, and it is possible to wrap the film with the sandwich in close contact. In addition, the contents of the sandwich do not adhere to the film during packaging, the appearance is not deteriorated and the commercial value is not lowered, and it can be highly evaluated as such.

However, in the above-mentioned package, there is no portion extending outward from each side of the sandwich, and the package body is gripped when the package is handled at a store or the like. There is a drawback that the product may be projected to the outside, which requires careful handling. Further, when opening the package, the film folded along the inclined surface of the sandwich is pulled by fingers, but it is also pointed out that the opening is complicated because a plurality of films are overlapped on the inclined surface.

[0007]

[0012]

[First Embodiment] FIG. 1 is a perspective view of a package according to the first embodiment, in which a triangular sandwich 14 is tightly wrapped with a transparent film 12. Formed. The sandwich 14 packaged in the packaging body 10 has an isosceles triangular shape having one long side 14a and two short sides 14b, 14b on the side surface. The sandwich 14 is a stack of a plurality of sets of sandwiches, and has a required thickness dimension.

That is, the bottom surface of the sandwich 14
The width dimension (dimension in the direction parallel to the long side 14a of the sandwich 14) m is set to be larger than the dimension m ₁ of the long side 14a of the sandwich 14 (on the cut surface where the contents are most visible) and on both side surfaces. The transparent film 12 thus formed is wrapped around and formed into a tubular shape, and a seal is applied at its longitudinally overlapping portion (see FIG. 3). The "seal" is used in the sense of including fusing, welding, or adhering, and in the examples, the film 12 is provided with a fusing seal. Further, in the examples, as one of the most preferable examples for carrying out the present invention, the position of the fusing seal line 15 of the tubular film is located at one of the substantially central positions in the width direction of the sandwich facing the inclined surface of the sandwich 14. The seal line 15 is formed so as to prevent the contents of the sandwich 14 from being exposed to the most visible bottom surface (cutting surface when a triangular sandwich is manufactured) to make the sandwich 14 unattractive. . However, the position where the fusing seal line 15 is formed is not limited to this, and the fusing seal may be provided at two positions on the outer circumference of the tubular film. In addition, when sealing is applied to a plurality of portions of the film 12, it is also possible to use fusing, welding, adhesion or the like together.

As shown in FIG. 4, the portion of the film 12 wound around the sandwich 14 facing each inclined surface is folded along the inclined surface with the side 14d where the inclined surfaces contact each other as a reference. The laterally extending portions 16 and 16 of the film 12 extending outward from the left and right short sides 14b and 14b of each inclined surface of the sandwich 14 are shown in FIG.
As shown in FIG. 7, the short sides 14b, 14b are bent along the inclined surface with reference to them. Further, the downward extending portion 19 of the film 12 extending outward from the side 14c where one of the inclined surfaces of the sandwich 14 and the bottom surface are in contact with each other is bent along the inclined surface with the side 14c as a reference. It is superposed on the laterally extending portions 16, 16. And the downward extending portion 19 and the lateral extending portions 16, 16 are
It is attached with an adhesive tape, a welding seal, an adhesive, or the like.

In the downward extending portion 18 of the film 12 extending outward from the side 14c where the other inclined surface of the sandwich 14 contacts the bottom surface, the lateral extending portions 16, 16 are provided.
A point-shaped seal 30 having a required width is provided in the thickness direction of the sandwich 14 at a portion near the side 14c in the overlapping portion. In addition, a seal 32 parallel to the dot-shaped seal 30 is provided at a portion of the lower extension 18 that is separated from the position where the dot-shaped seal 30 is formed by a predetermined distance to the outside.
6 and 18 are designed not to be separated. This seal 3
As 2, a welding seal or a dot seal can be appropriately selected. Furthermore, both seals 30 and 3 in the downward extension portion 18
A V-shaped opening notch 34 is formed at a position facing between the two. The V-shape is most preferable as the cut 34, but other shapes such as a U-shape, a semi-circle, a trapezoid or a U-shape can be adopted. As shown in FIG. 2, on the bottom surface side of the sandwich 14 in the downward extending portion 18,
Display 3 for indicating the opening direction by the opening notch 34
It is recommended to print 6.

Thus, the package 10 is the sandwich 1
Since the downward extending portion 18 extends outward from the side 14c of 4, the extending portion 18 can be gripped and handled, the sandwich 14 is not crushed, and the opening notch 34 can be easily used. It can be opened.

[0017]

[Operation of the First Embodiment] In the case of manufacturing the package according to the first embodiment, a film drawn from a roll body in which a strip-shaped film having a width dimension m larger than the length of the long side 14a of the sandwich 14 is wound. 12 by sandwich 14
Is cylindrically surrounded so that its long side 14a is located at a substantially central portion of the film width m, and then the film 12 is fusion-sealed along the width direction. As a result, the bottom surface and both side surfaces of the triangular sandwich 14 are surrounded by the tubular film 12 that is fusion-sealed, as shown in FIG. The film 12 in which the sandwich 14 is packaged in a tubular shape may be welded or adhered in the width direction, and then the film 12 may be cut.

Next, as shown in FIG.
The film 12 facing each of the inclined surfaces is bent along the inclined surfaces with reference to the side 14d where the inclined surfaces contact each other. Further, a V-shaped opening notch 34 is formed in the downward extending portion 18 of the film 12 that extends outward from the side 14c where the bottom surface of the sandwich 14 and one inclined surface are in contact with each other. Then, the side extending portion 16 that extends outward in contact with the one short side 14b located on each inclined surface is provided in FIGS.
As shown in FIG. 7, after bending along the inclined surface with the short side 14b as a reference, as shown in FIG. 7, a side extending portion 16 that extends outward in contact with the other short side 14b is formed on the inclined surface. Fold along.

Before the side extending portions 16 and 16 are bent along the inclined surface, the film 12 already bent along the inclined surface and the bottom surface of the sandwich 14 as shown in FIG. Each side 14c in contact with each inclined surface
Temporary seals 26, 26 that are heat-welded may be provided on the overlapping portion with the film 12 that extends outward from the. In this case, it becomes possible to easily bend the side extending portions 16, 16 to the inclined surface. In addition, temporary seals 26, 26
Does not need to be applied over the entire length of the sandwich 14 in the thickness direction, and the desired purpose can be achieved by applying it near the end of the side 14c as shown in the figure.

After that, as shown in FIG. 1, a downward extending portion 19 extending outward from the side 14c where the bottom surface of the sandwich 14 and one of the inclined surfaces are in contact is formed along the inclined surface with the side 14c as a reference. Then, the extending portion 19 is attached to the side extending portions 16, 16 which are already folded. In addition, the bottom extension portion 18 extending outward from the side 14c where the bottom surface of the sandwich 14 and the other inclined surface are in contact with each other, and a position close to the side 14c in the overlapping portion with the side extension portions 16 and 16. Then, the point seal 30 is applied to the entire length of the sandwich 14 in the thickness direction. Further, the package 10 is obtained by providing a seal 32 parallel to the point seal 30 at a position spaced apart from the point seal 30 by a predetermined distance.

Further, as shown in FIG. 2, an indicator 36 oriented in the opening direction may be printed on the film 12 in which the opening notch 34 is formed. Thereby, the opening position and the direction can be easily visually recognized. It should be noted that one of the downward extending portions 19 that is bent along the inclined surface of the sandwich 14 has the lateral extending portions 16, 16 before the bending.
Alternatively, the overlapped portion may be welded and sealed over the entire length of the sandwich 14 in the thickness direction. Further, when performing the fusion-sealing, if a film having a double-sided sealing property such as a single film of biaxially oriented polypropylene is used as a packaging film, the lower extension portion 19 and the side extension portions 16 and 16 can be formed. The overlapped portion of is fixed to form a cohesive state, and the downward extending portion 19 can be easily bent to the inclined surface. Instead of performing the welding seal over the entire length of the sandwich 14 in the thickness direction, the overlapping portion between the downward extending portion 19 and the lateral extending portions 16 and 16 may be spot-sealed.

The package 10 manufactured in this way is
By the film 12 continuously drawn from the roll body,
Since the sandwich 14 can be packaged, automation can be facilitated and manufacturing efficiency can be significantly improved.
Further, as shown in FIG. 3, since the film 12 is wrapped around the sandwich 14 in the thickness direction, the width dimension m of the film 12 is not affected by the change in the thickness dimension due to the change in the number of sandwich 14 layers. This can be easily done by changing the cutting length of the film 12 without changing the length. Moreover, since the package 10 can be handled by grasping the downward extending portion 18 extending outward from the side 14c of the sandwich 14 without grasping the sandwich 14 itself, the sandwich 14 can be crushed or the contents can be exposed to the outside. It can be prevented from protruding. In addition, while holding the tip of the downward extension portion 18 with one finger, hold the opening notch 34 with the other finger, and pull in the direction indicated by the display 36, the packaging body 10 concerned can be obtained. It can be opened easily. Moreover, since the film 12 on the side that is torn by the opening notch 34 is one (the bottom surface side of the sandwich 14), it can be torn smoothly.

[0023]

[Second Embodiment] FIG. 8 shows a packaging body according to the second embodiment. The packaging body 10 basically has the same structure as the packaging body 10 shown in the first embodiment. Although it has, the film 12 of the packaging body 10 according to the second embodiment,
