Description

The present invention relates to a gripping container and a gripping piece, and more particularly to a gripping container and a gripping piece thereof suitable for packaging foods heated in a microwave oven, an oven, or the like.

Patent Document 1 discloses a heat insulating container in which a paper cup body and a paper cylinder are combined. The tubular body is formed with a grip piece partitioned by a fold line and a U-shaped cut line. By folding along the fold line, the grip piece is raised from the tubular body and protrudes outward from the tubular body. By holding the grip piece that spreads outwards with your hands, you can carry the heat-insulated container without your hands touching the heat-insulated container and feeling the heat.

Patent Document 2 discloses a cup-shaped container including a container body and a cloak covering the outer peripheral portion of the body wall of the container body. Most of the cloak can be used as a handle, leaving the circumferential band and the vertical band. By holding the handle, you can hold the container without feeling the heat.

Japanese Patent No. 4360708 Japanese Patent No. 4226565

The grip piece connected to the tubular body in the fold line is liable to tear (tear) from both ends of the fold line. In the heat insulating container described in Patent Document 1, since the cut line is U-shaped, the direction toward the end point (end) of the cut line at both ends of the folded line is upward (the top of the cut line is located at the upper end of the grip piece). do). The force applied to the grip piece when the heat insulating container is lifted by holding the grip piece by hand is also upward. For this reason, when the grip piece is grasped and the heat insulating container is lifted, a tear (tear) in the direction of extending the upward cut line is formed at both ends of the folding line (base of the grip piece) connecting the grip piece to the tubular body. It tends to occur in the shape. If the fold line (the base of the grip piece) tears even slightly at both ends of the fold line or at either end, the tear spreads from there and the grip piece is likely to be torn off.

Although the cup-shaped container described in Patent Document 2 has a high handle strength, since most of the mantle is used for the handle, the heat insulating performance is greatly deteriorated.

It is an object of the present invention to provide a gripping surface portion which is less likely to be torn (tear).

Another object of the present invention is to make it possible to form a gripping surface portion that is less likely to be torn (tear) without significantly deteriorating the heat insulating performance.

The gripping container according to the present invention includes a bottomed container body and a paper outer cylinder that is covered and fixed to the outside of the body of the container body, and is located at two opposite locations of the outer cylinder. ， A gripping surface portion that can be folded outward along the fold ruled line is formed by separating the fold line separated by a fold ruled line having a predetermined length and a break line connecting both ends of the fold ruled line. The break line is formed in an inverted U shape above the fold ruled line.

The inverted U-shape means a shape in which the U-shape is turned upside down, and means a shape in which a line extending upward from each of two lower ends (end points and end points) located at intervals is connected upward. The area surrounded by the folded ruled line and the inverted U-shaped breaking line is the gripping surface portion. The gripping surface portion (inverted U-shape) may be, for example, semi-circular or semi-elliptical. It may be a rectangle (quadrangle) with both corners rounded.

According to the present invention, since the breaking line forming the gripping surface portion formed on the outer cylinder is an inverted U-shape, the direction toward the end point (end point) of the breaking line is downward at both ends of the folded ruled line (of the breaking line). The top is located at the bottom of the grip surface). On the other hand, when the gripping surface is held by hand and the container is lifted, the force applied to the gripping surface is upward, so when the gripping piece is gripped and the container is lifted, the folding ruled line connecting the gripping surface to the outer cylinder (the base of the gripping surface). ), The outer cylinder is difficult to tear in the direction of extending the downward break line, and therefore the gripping surface portion can be difficult to tear. Further, since the gripping surface portion is formed at two opposite locations of the outer cylinder, the range excluding the range of the gripping surface portion can be continuously covered by the outer cylinder, and the heat insulating performance is not significantly deteriorated.

Preferably, curved cuts are connected to each of both ends of the folded ruled line. It is possible to prevent or reduce the tearing of the outer cylinder at both ends of the folded ruled line when the gripping surface portion is folded.

The present invention also provides a grip. The grip piece according to the present invention is made of paper fixed to the outside of the body of the bottomed container body, and is formed by a fold ruled line having a predetermined length and a break line connecting both ends of the fold ruled line. By separating the partitioned break line, a gripping surface portion that can be folded outward is formed along the folded ruled line, and the broken line is formed in an inverted U shape above the folded ruled line. It is a feature.

The grip piece according to the present invention is used by being fixed to the outside of the body of the container body. Since the break line that divides the grip surface portion formed on the grip piece is an inverted U shape, the direction toward the end point (end point) of the break line is downward at both ends of the folded ruled line, while holding the grip surface portion by hand. Since the force applied to the gripping surface when the container is lifted is upward, when the gripping piece is gripped and the container is lifted, the gripping surface is connected to the gripping piece at both ends of the fold ruled line (base of the gripping surface) facing downward. The grip piece is difficult to tear in the direction of extending the break line, and therefore the grip surface portion can be difficult to tear.

It is a developed view of the outer cylinder which constitutes the heat insulating paper container of 1st Example. It is a perspective view of the heat insulating paper container with the gripping surface raised. It is an enlarged plan view of the grip piece constituting the paper container of 2nd Example. It is a perspective view of the paper container of 2nd Example.

Hereinafter, the gripping paper container according to the present invention will be described in detail with reference to the first to second embodiments.

1 to 4 show the heat insulating paper container of the first embodiment. 1 is a perspective view of the heat insulating paper container, FIG. 2 is a partial vertical sectional view of the heat insulating paper container along the line II-II of FIG. 1, FIG. 3 is a developed view of the outer cylinder (blank view), and FIG. 4 is a gripping surface portion. It is a perspective view of a heat insulating paper container in a state where is folded outward.

The heat insulating paper container 1 is composed of a lid material 10, a body portion 12, a bottom portion 13, and an outer cylinder 14.

The body portion 12 has a cylindrical shape with a slightly larger diameter at the upper part and a smaller diameter toward the lower part, and the upper surface to be opened is closed by the lid material 10. The upper peripheral peripheral portion of the body portion 12 is wound outward to form a so-called curl portion 11. The bottom portion 13 is circular, and the peripheral portion thereof is bent downward (bending portion 13a). The bottom portion 13 fits snugly into the lower opening of the body portion 12, the lower end portion of the body portion 12 is folded inward (folded portion 12a), and the folded portion 12a sandwiches the bent portion 13a of the bottom portion 13. Both the inner and outer surfaces of the bent portion 13a of the bottom portion 13 and the inner surface of the lower end portion of the body portion 12 sandwiching the bent portion 13a are bonded or welded. For the body 12 and the bottom 13, for example, a paper base material and a laminated structure in which a polyolefin resin is laminated on the inner surface thereof are used. The body 12 and the bottom 13 have a low density polyethylene resin, a medium density polyethylene resin, and a high density polyethylene resin having a thickness of 5 to 100 μm, preferably 20 to 80 μm, on the inner surface of a paperboard material having a basis weight of about 190 to 450 g / m ² . It is also possible to use a high-density polyethylene resin or a linear low-density polyethylene resin formed by an extruded coating. This prevents the contents from penetrating into the paperboard, improves the suitability for protecting the contents, raises the cup molding suitability at the bottom 13, curl portion 11, and the body sticking portion of the body 12, and heat seals the curl portion 11 of the lid material 10. It also has the effect of improving the sealing performance. The bottom 12 and the bottom 13 form a bottomed paper cup body (container body). The container body may be a paper base material laminated with a polystyrene layer, a polyethylene layer, a polyethylene terephthalate layer, a polypropylene layer, or the like, or may be made of a resin such as polypropylene, polystyrene, or polyethylene terephthalate.

The outer cylinder 14 is formed by adhering the side portions of a slightly arcuate blank material (FIG. 3) to each other to form a cylindrical shape, and then folding the lower end portion inward and adhering the outer cylinder 14. The folded portion is indicated by reference numeral 14a in FIG. The adhesive portion 14b used for adhering the side portions is shown by hatching in FIG.

Like the body 12, the outer cylinder 14 also has a cylindrical shape with a large diameter at the top and a smaller diameter toward the bottom. The body portion 12 having the bottom portion 13 is inserted (fitted) into the outer cylinder inner body 14 from above. The upper end of the outer cylinder 14 enters the gap inside the curl portion 11 on the peripheral edge of the upper end of the body portion 12, and the lower end portion follows (contacts) the outside of the lower end portion of the body portion 12. The outer cylinder 14 is fixed to the body portion 12 with an adhesive. For example, the folded-back portion 14a and the body portion 12 at the lower end portion of the outer cylinder 14, the upper end portion and the curl portion 11 of the outer cylinder 14, or both of them can be bonded. The lower end of the outer cylinder 14 should not protrude below the lower end (threading) of the body portion 12. However, it is also possible to project the lower end of the outer cylinder 14 below the lower end of the body portion 12 and support the entire heat insulating paper container 1 with the outer cylinder 14. Further, the lower end portion of the outer cylinder 14 may be extended straight as it is without being folded back. It is preferable to form a gap for heat insulation between the outer cylinder 14 and the body portion 12. However, the gap between the outer cylinder 14 and the body 12 is not always necessary.

The outer cylinder 14 is made of paper as the main strength material. The outer cylinder 14 may be composed of only a paper base material, or a polystyrene layer, a polyethylene layer, a polyethylene terephthalate layer, a polypropylene layer, or the like may be laminated on the outer layer. As the paper material of the outer cylinder 14, a card-based or coated ball-based paperboard having a basis weight of 230 to 450 g / m ² can be used.

The lid material 10 is a multi-layered stack of a sealant layer for adhering the lid material 10 on the upper surface of the curl portion 11, a paper layer for printing characters, figures, etc., and a protective layer for protecting the paper layer. Can be used. An aluminum layer for maintaining the shape may be laminated between the sealant layer and the paper layer. A base film such as nylon (NY) or polyethylene terephthalate (PET) dry-laminated with an easy peel layer may be used for the lid material 10.

With reference to FIGS. 1, 3 and 4, two gripping surface portions 20 are partitioned on the outer cylinder 14. Each of the gripping surface portions 20 is partitioned on substantially opposite sides of the cylindrical outer cylinder 14.

The gripping surface portion 20 is composed of a part of the outer cylinder 14, and is connected to the folded ruled line 21 formed on the outer cylinder 14 and both ends of the folded ruled line 21 in an inverted U shape so as to extend upward in an arc shape. It has a shape that protrudes upward, surrounded by a break line 22 formed on the outer cylinder 14. The fold ruled line 21 is preferably formed so as to be curved upward as shown in the figure, but the fold ruled line 21 may be formed in a straight line in the circumferential direction. Further, at each of both ends of the folded ruled line 21, a reverse cut line 23 protruding outward (downward) in an arc shape is inserted.

The break line 22 can be configured by a cut line penetrating the outer cylinder 14 except for a short connecting portion 14c provided in the middle thereof. However, the break line 22 may be formed by connecting a plurality of short cut lines with a plurality of short joints, or may be formed by a perforation connecting the cut lines intermittently. By the connecting portion 14c, the gripping surface portion 20 is joined to the outer cylinder 14 substantially flush with the outer cylinder 14 until it is cut off from the outer cylinder 14 as described below.

With reference to FIG. 4, the joint portion 14c is torn off and the grip surface portion 20 is folded outward at the fold ruled line 21 by putting a fingernail or a finger on the break line 22 and turning (raising) the grip surface portion 20 downward. Since the return cut lines 23 are formed at both ends of the fold ruled line 21, the outer cylinder 14 is not easily torn at both ends of the fold ruled line 21 when the gripping surface portion 20 is folded outward.

The gripping surface portion 20 is cut off from the outer cylinder 14 along the break line 22 in a state of being connected to the outer cylinder 14 at the folding ruled line 21, and protrudes outward. As described above, since the folding ruled line 21 connecting the gripping surface portion 20 to the outer cylinder 14 is slightly curved upward, the gripping surface portion 20 turned over from the outer cylinder 14 has a shape slightly curved upward when viewed from the side. Take on. After folding both gripping surfaces 20, the heat insulating paper container 1 is placed in, for example, a microwave oven, and the contents are heated.

Since the breaking line 22 forming the gripping surface portion 20 formed on the outer cylinder 14 is inverted U-shaped, the direction toward the end point of the breaking line 22 at both ends of the folded ruled line 21 is downward (the top of the breaking line 22 is). Located at the lower end of the grip surface 20). On the other hand, when the gripping surface portion 20 is held by hand and the heat insulating paper container 1 is lifted, the force applied to the gripping surface portion 20 is upward. Therefore, when the heat insulating paper container 1 is lifted by grasping the two gripping surface portions 20, downward breaking lines 22 are formed at both ends of the folded ruled line 21 (the base of the gripping surface portion 20) connecting the gripping surface portion 20 to the outer cylinder 14. The outer cylinder 14 is difficult to tear in the direction in which it extends, and therefore the gripping surface portion 20 can be difficult to tear.

As described above, the gripping surface portion 20 needs to be raised by putting a fingernail or a finger on the breaking line 22 and turning it downward. A convex portion (embossed portion) or a concave portion (debossed portion) may be formed on the gripping surface portion 20 in order to make it easier to raise the gripping surface portion 20 (make it easier to put a fingernail or a finger on it). A notch is made in the tip of the gripping surface portion 20, a protruding portion that is continuous and slightly protrudes outward is formed in the outer cylinder 14, and the notch portion adjacent to the gripping surface portion 20 is removed. It may be formed in a cylinder 14. It becomes easier to put a fingernail or a finger on the gripping surface portion 20, and it becomes easier to raise the gripping surface portion 20.

5 and 6 show a second embodiment, FIG. 5 shows a plan view of the grip piece 30, and FIG. 6 shows a perspective view of the paper container 2 to which the grip piece 30 is attached.

In the first embodiment described above, the heat insulating paper container 1 is provided with an outer cylinder 14, and a gripping surface portion 20 is formed on a part of the outer cylinder 14. On the other hand, the paper container 2 of the second embodiment is different in that the outer cylinder is not provided and the body portion 12 is exposed.

The grip pieces 30 shown in FIG. 5 are mounted at two locations on opposite sides of the body portion 12. Like the outer cylinder 14 described above, the grip piece 30 is made of paper as the main strength material, has a rectangular outer shape, and is formed with the grip surface portion 20 of the first embodiment described above. .. The grip piece 30 may be fixed to the surface of the body portion 12 by adhesion or welding, or the upper edge portion of the grip piece 30 may be inserted into the curl portion 11 and fixed to the body portion 12 by adhering the lower portion. ..

It is the same as in the first embodiment that the gripping surface portion 20 is projected outward by putting a fingernail or a finger on the breaking line 22 to raise the gripping surface portion 20 and folding it outward. Further, as in the first embodiment, since the breaking line 22 for partitioning the gripping surface portion 20 formed on the gripping piece 30 is an inverted U shape, the direction of the breaking line 22 at both ends of the folded ruled line 21 is downward (). The top of the break line 22 is located at the lower end of the grip surface portion 20), which is the opposite of the upward force applied to the grip surface portion 20 when the grip surface portion 20 is held by hand and the paper container 2 is lifted. Therefore, when the gripping surface portion 20 is gripped and the paper container 2 is lifted, the downward breaking line 22 extends at both ends of the folding ruled line 21 (the base of the gripping surface portion 20) connecting the gripping surface portion 20 to the gripping piece 30. The grip piece 30 is difficult to tear, and therefore the grip surface portion 20 can be difficult to tear.

In the above-described embodiment, the heat insulating paper container 1 fixed by covering the outside of the paper cup body (paper body 12 and bottom 13) with the paper outer cylinder 14 and the paper grip piece 30 on the outside of the paper cup body 30. Although the paper container 2 to which the paper container 2 is fixed has been described, a resin cup body can be used instead of the paper cup body.
