The container body 10 is formed using, for example, a paper material as a base material. For example, a base paper having a basis weight of 200 g / m ² or more is used for the container body 10. Specifically, in the container body 10, a film formed by a resin layer or the like formed of a resin material such as a polyolefin resin such as polyethylene or a polyester resin is coated on the surface of the paper base material. The container body 10 is bottomed and is formed in a truncated cone-shaped cup shape. Specifically, the container body 10 is formed by gradually increasing the diameter from the bottom portion toward the end portion that opens.

The container sleeve 11 has the same axis as the container body 10 and is formed in a cylindrical shape that is inclined at the same inclination angle as the outer peripheral surface of the container body 10. The container sleeve 11 includes a trunk portion 21, a pair of handles 22 provided on the trunk portion 21, and a hinge portion 23 that couples the trunk portion 21 and the handle 22. The container sleeve 11 is, for example, a paper material in which a water repellent having a water-resistant action is applied to a paper base material, a resin layer formed of a resin material such as a polyolefin resin such as polyethylene, or a polyester resin. Is formed by a paper material coated with a laminate. The fiber orientation of the paper base of the container sleeve 11 preferably extends along the axis of the container sleeve 11. The paper base material is preferably a base paper having a basis weight of 100 g / m ^{2 to} 400 g / m ² and a thickness of 120 μm to 500 μm. Further, the water absorption of the cup defined in JIS P8140 of the sleeve 11 for containers is preferably 40 g / m ² or less, more preferably 30 g / m ² or less at a contact time of 30 seconds on both the front surface and the back surface, more preferably 25 g / m ^2. More preferably, it is m ² or less.

  The body portion 21 is formed in a cylindrical shape with the same inclination angle as the outer peripheral surface of the container body 10 by a paper base material. The body portion 21 is integrally formed with a pair of grips 22 on a part of the outer peripheral surface thereof. The trunk | drum 21 is equipped with the 1st bead 24 provided with two or more on the outer peripheral surface along the inclination direction and spaced apart from the handle 22 in the circumferential direction. The body portion 21 includes a punched portion 25 that is opened by being cut out at a part adjacent to the handle 22.

  The first bead 24 is provided along the axial center of the trunk portion 21, and is formed by a part of the outer surface of the trunk portion 21 being recessed in a linear shape. The first bead 24 is spaced apart from the handle 22 between the pair of grips 22. A plurality are arranged. The plurality of first beads 24 are, for example, indentations formed by being pressed from the outer surface of the body portion 21. The first bead 24 protrudes from the inner surface of the trunk portion 21. Thereby, when the trunk | drum 21 is assembled integrally with the container body 10, the 1st bead 24 spaces apart the inner surface of the trunk | drum 21 between the adjacent 1st beads 24, and the outer surface of the container body 10, and a container body. A gap is formed between 10 and the body 21. The direction in which the first bead 24 extends is not particularly limited, but is preferably inclined in the range of 0 ° to 45 ° with respect to the axis of the barrel portion 21. More preferably, it is provided along the axis of 21.

  A pair of grips 22 are provided at symmetrical positions on the outer surface of the body portion 21. The handle 22 is formed in a tongue shape having a semicircular tip by cutting a part of the body portion 21 into a U shape. The handle 22 is formed such that its axis extends along the axis of the trunk portion 21. The handle 22 is formed to be rotatable with respect to the container body 10 around the hinge portion 23. The handle 22 protrudes from the outer peripheral surface of the trunk portion 21 by rotating around the hinge portion 23 in a direction away from the container body 10. The handle 22 includes a plurality of second beads 27 that are concave and convex portions extending from the hinge portion 23 toward the tip thereof.

  When the handle 22 is in a position where the handle 22 contacts the container body 10, in other words, when the outer surface of the handle 22 is flush with the outer surface of the body portion 21, the extending direction of the second bead 27 is the same as that of the first bead 24. It is formed along the surface direction of the body portion 21 in the same direction as the extending direction. The second bead 27 is provided along the axial center of the trunk portion 21 and is formed by a part of the outer surface of the trunk portion 21 being recessed in a linear shape. The second bead 27 protrudes from the inner surface of the trunk portion 21. The second bead 27 is an indentation formed by being pressed from the outer surface of the trunk portion 21. A plurality of second beads 27 are provided in the handle 22, in the present embodiment, three. The second bead 27 is formed such that one end adjacent to the hinge part 23 is separated from the hinge part 23. The direction in which the second bead 27 extends is not particularly limited, but is preferably inclined in the range of 0 ° to 45 ° with respect to the axial center of the trunk portion 21. More preferably, it is provided along the axis of 21.

  The hinge part 23 is formed by recessing a part adjacent to the handle 22 on the outer surface of the body part 21. When the container sleeve 11 is provided on the container body 10, the hinge part 23 is arranged on the end side where the container body 10 opens. The hinge part 23 is an indentation formed on the outer surface of the body part 21. The hinge portion 23 is formed in an arc shape. More specifically, the hinge portion 23 is formed in an arc shape having a radius of curvature equal to or close to the radius of curvature formed by the outer peripheral surface of the container body 10. It is preferable that the hinge part 23 is spaced apart from an intermediate point of the hinge part 23 with respect to a straight line connecting both ends of the hinge part 23. In other words, it is preferable that both end portions of the hinge portion 23 are located above the central portion. The vertical distance from the straight line connecting both ends of the hinge part 23 to the intermediate point of the hinge part 23 is preferably in the range of 1 mm to 10 mm, and more preferably in the range of 3 mm to 8 mm.

  Next, the blank 11A of the container sleeve 11 configured as described above will be described with reference to FIGS. In FIG. 5, the chain line indicates the indentation of the blank 11 </ b> A, and the solid line indicates the cut portion. The indentation is formed by being pressed from the outer surface of the blank 11A. Moreover, a cutting | disconnection part is the site | part cut | disconnected at the time of formation of blank 11A called what is called a cutting edge.

  As shown in FIG. 5, the sleeve 11 for containers is comprised by the blank 11A. The blank 11A is configured by forming a paper material into a predetermined shape by punching.

  The blank 11A is formed by cutting a paper material into a shape in which the container sleeve 11 is developed and having an adhesive margin at an end thereof by punching.

  The blank 11 </ b> A includes a band-shaped portion 31 that forms the body portion 21 by bonding both ends, and a U-shaped first cutting portion 32 that is provided in the band-shaped portion 31 and that forms a pair of grips 22. I have. Further, the blank 11 </ b> A includes a plurality of first indentations 34 constituting the first bead 24 provided in the belt-like portion 31, a notch portion 35 constituting a punching portion 25 provided in the belt-like portion 31, and the belt-like portion 31. And a plurality of second indentations 37 formed in the first cutting portion 32. The blank 11 </ b> A includes a third indentation 38 that constitutes the hinge portion 23, which is continuous between the end portions of the first cutting portion 32, and an adhesive margin portion 39 provided at one end portion of the belt-like portion 31. Yes.

  For example, a plurality of non-continuous portions 32 a are formed in a part of the first cutting portion 32. The non-continuous portion 32 a is a non-cut portion that is intermittently disposed at a part of the first cut portion 32, and makes the outer and inner belt-like portions 31 of the first cut portion 32 continuous. The first indentation 34 constitutes the first bead 24. For example, the plurality of first indentations 34 are a part of the first indentations 34, more specifically, a part of the first indentations 34 located substantially in the center of the belt-shaped portion 31 and the first margin adjacent to the adhesive margin 39. The indentation 34 is provided with a second cutting portion 40 intermittently, in other words, a plurality of discontinuous portions formed in part. The second cutting portion 40 is a so-called lead that guides a portion of the container sleeve 11 that is formed by bonding the adhesive margin portion 39 to the end portion of the strip portion 31 to be bent. The second indentation 37 is formed to be separated from the third indentation 38 and constitutes the second bead 27. The third indentation 38 is formed in an arc shape with a predetermined curvature and constitutes the hinge portion 23.

  The blank 11 </ b> A configured in this way constitutes the container sleeve 11 by adhering the margin portion 39 to the end of the band-shaped portion 31. The container sleeve 11 is inserted into the container body 10 as a cylindrical shape, for example, and the container sleeve 11 is bonded to the container body 10 with an adhesive. Thus, the container 1 including the container body 10 and the container sleeve 11 is configured. Further, the container sleeve 11 can be folded into a strip shape by folding the first indentation 34 provided with the second cutting portion 40.

Next, for the first evaluation test to the fourth evaluation test in which the example of the container 1 using the container sleeve 11 as the container body 10 according to the present embodiment is compared with each comparative example, and the container 1 is evaluated. This will be described below. The base paper used for the sleeve had a basis weight of 310 g / m ² and a thickness of 380 μm, and the fiber orientation of the base paper was the same as the axial direction of the sleeve 11 for containers. Further, Cobb water absorption of the container sleeve 11 surface 21g / ^{m 2,} and a rear surface 23 g / ^{m 2.} The axial length of the container sleeve 11 was 72 mm, the radius of curvature of the hinge portion 23 was 75 mm, and the outer peripheral radius of curvature of the container body 10 was 65.1 mm.

  According to the second evaluation test, the container 1 could be stably held by the low-temperature handle 22 even when the contents were cooked at a high temperature by cooking with a microwave oven. Moreover, from the result of the comparative example 3, it was possible to improve heat insulation even by heating the contents by heat cooking by providing a plurality of first beads 24 in the body portion 21. Note that both Comparative Example 3 and Comparative Example 4 were high in temperature, and it was difficult to hold them with bare hands.

(Third evaluation test)
As a third evaluation test, each container of Example 3 and Comparative Example 5 shown below, in which 170 g of frozen udon, 50 g of ingredients, and 275 g of water were put into the container body 10, was frozen and then 600 W in a microwave oven. Cook for 6 minutes. Immediately after cooking, the handle 22 of Example 3 and Comparative Example 5 is taken out of the microwave oven and compared sensuously.

(Example 3)
A container 1 is used in which a container sleeve 11 formed of a paper material having a water repellent coated on the outer surface is assembled into a container body 10. The width of the handle 22 of the container sleeve 11 is 50 mm.

(Comparative Example 5)
A container 1 is used in which a container sleeve 11 formed only of a paper base material having no water resistance is assembled in a container body 10. The width of the handle 22 of the container sleeve 11 is 50 mm.

(Result of third evaluation test)
As a result of the third evaluation test, the container 1 of Example 3 has the handle 22 of Example 1 in which the strength (rigidity) of the handle 22 is not cooked by the above-described microwave oven even when cooked by the microwave oven. The strength equivalent to 22 was maintained, and the handle 22 was able to stably support the strength.

  On the other hand, although the container 1 of Comparative Example 5 was able to be stably supported by the handle 22, compared with the container 1 of Example 3, the paper base material absorbs water during freezing, and the strength of the handle 22 is increased. Declined.

(Fourth evaluation test)
As a fourth evaluation test, 170 g of frozen udon and 275 g of water were put into the container body 10, and the ease of holding and the ease of holding the handle 22 of each container 1 of Examples 4 to 6 shown below was sensed. Compare.

(Example 6)
A container 1 in which a container sleeve 11 is assembled to a container body 10 is used. The width of the handle 22 of the container sleeve 11 is 50 mm.

(Result of 4th evaluation test)
As a result of the fourth evaluation test, the containers 1 of Examples 4 to 6 were both supported stably by the handle 22. It should be noted that the ease with which the handle 22 is caused and the ease with which the handle 22 is raised are easier to cause and can be supported more stably as the width of the handle 22 is wider.

  According to the container 1 configured as described above, when a high-temperature food or the like is put in the container body 10 as the contents, or when the contents in the container body 10 are cooked, the user can remove the portion 25. The handle 22 exposed to is held, and the handle 22 is rotated so as to be separated from the container body 10. Thereby, the discontinuous part 32 a of the first cutting part 32 is broken, and the handle 22 is separated from the body part 21. At this time, the bending of the hinge portion 23 is guided by the third indentation 38 and constitutes the rotation axis of the arc-shaped handle 22.

  The user can hold the container body 10 by holding the handle 22. In addition, since the container body 10 and the container sleeve 11 are formed in a cylindrical shape whose outer peripheral surfaces are inclined, the container body 10 and the container body 10 are accommodated when the user supports the handle 22. Depending on the weight of the contents, force is applied in the direction in which the container body 10 and the container sleeve 11 are fitted. Therefore, the container body 10 and the container sleeve 11 are peeled off by heat, or the container sleeve 11 is simply inserted into the container body 10 without bonding the container body 10 and the container sleeve 11 with an adhesive. Even if it exists, when the handle 22 is supported, the container body 10 and the container sleeve 11 are fitted, and the container body 10 can be stably supported.

  Further, since the user supports the handle 22 that is separated from the container body 10, the user can support the container body 10 even when the contents or the container body 10 itself is at a high temperature. Further, the handle 22 has a plurality of second beads 27 therein. Moreover, since the hinge part 23 is formed in circular arc shape, it will curve only by rotating the handle 22 in the direction away from the container body 10. FIG. As a result, the handle 22 has improved rigidity and can reliably support the container body 10 containing the contents. In addition, since the rigidity of the handle 22 is improved by the second bead 27, the container body 10 can be held even if the temperature of the handle 22 is increased or the strength is reduced due to the moisture absorption of the paper base material. It becomes possible. Further, since the handle 22 rotates around the hinge portion 23 formed in an arc shape, it is possible to prevent the rotation of the handle 22 from being hindered even if the body portion 21 is formed in a cylindrical shape. Become.

  Furthermore, since the second bead 27 is provided along the axial center of the body portion, even if the tensile elongation strength of the handle 22 is reduced due to formation of the indentation, the handle 22 can be prevented from being broken and rigid. Can be improved sufficiently. Specifically, as a general paper base material property, when the second bead 27 is formed by an indentation, the fiber constituting the paper base material is cut due to molding damage, so that the tensile elongation strength of the portion is lowered. To do. In the present invention, by providing the second bead 27 along the axial center of the trunk, it is possible to prevent the load when the container body 10 is supported by the handle 22 from being concentrated on the second bead 27. The breakage of the handle 22 starting from the bead 27 can be prevented.

  Moreover, the sleeve 11 for containers improves heat insulation by providing the 1st bead 24 in the trunk | drum 21, and separating the inner surface of the trunk | drum 21 between the adjacent 1st beads 24 from the container body 10. FIG. In addition, the container sleeve 11 is configured such that the first bead 24 is not provided in the body portion 21 around the handle 22, thereby preventing the strength of the paper base material itself from being lowered, and the handle 22 is disposed in the container body. It is possible to warp in a direction away from the outer peripheral surface of the ten.

  Specifically, since the first bead 24 is constituted by the first indentation 34 in the blank 11A, the fibers constituting the paper base material are cut by the formation of the indentation, whereby the paper base material itself is stretched and stretched. Strength decreases. Further, when the handle 22 rotates, the weight of the contents concentrates on the end of the handle 22. For this reason, when the container 1 is supported by the handle 22, if the first bead 24 extending in the direction of gravity is provided on the end side of the handle 22, the first bead 24 may be broken as a starting point.

  However, the container sleeve 11 used in the container 1 is configured not to provide the first bead 24 on the body around the handle 22, thereby preventing a decrease in strength around the handle 22, and the container sleeve 11. Can be prevented. Furthermore, since the sleeve 11 for containers is comprised by making the planar blank 11A cylindrical, the site | part of the said trunk | drum 21 is made flat by setting it as the structure which does not provide the 1st bead 24 in the periphery of the handle 22. As a result, the grip 22 that is continuous with the body portion 21 at the discontinuous portion 32a is restored in a direction in which the portion located at the first cutting portion 32 becomes flat. Further, since the second bead 27 is formed on the handle 22, a gap is formed between the inner surface of the handle 22 and the outer surface of the container body 10 by the second bead 27. For this reason, when the handle 22 is slightly separated from the container body 10 and the user rotates the handle 22 from the extraction portion 25, the handle 22 can be easily detached and the usability can be improved.

  Further, the second bead 27 provided on the handle 22 is disposed away from the hinge portion 23, thereby making it possible to prevent breakage in the vicinity of the hinge portion 23 due to a decrease in strength of the paper base material due to formation of indentations. . Specifically, in the second bead 27 and the hinge part 23, the fibers constituting the paper base material are cut by the formation of the indentation, so that the tensile elongation strength of the paper base material itself at that portion is lowered. If the second bead portion 27 and the hinge portion 23 are connected to each other, the elongation strength of the connection portion is particularly lowered. Therefore, when the handle 22 is pulled in this state, the breakage occurs starting from the connection portion. May be easier.

  Furthermore, the container sleeve 11 is configured to have water resistance by adopting a paper material in which a water repellent is applied to the paper base material or a resin layer provided on the paper base material. Thereby, even if the container sleeve 11 is cooked by using a microwave oven or hot water, or when the contents are frozen and refrigerated while being put in the container 1, the paper base material absorbs water. Can be prevented. Thereby, the sleeve 11 for containers can prevent that the rigidity (strength) of the handle 22 falls. Furthermore, since the container sleeve 11 is configured to use a paper base material, the container sleeve 11 is excellent in discardability. Further, since the container body 10 can be transported by the handle 22, it is not necessary to directly touch the container body 10, and the contents can be transported hygienically.

Moreover, the fiber orientation of the paper base material of the container sleeve 11 is configured to extend along the axis of the container sleeve 11 (body portion 21), thereby improving the rigidity and tensile strength of the handle. it can. Furthermore, when processing the first bead 24 and the second bead 27 provided along the axial center of the body portion 21, the paper base material is stretched in a direction perpendicular to the fiber orientation, so that breakage during processing occurs. Can be difficult. In addition, the paper base material can secure sufficient rigidity of the paper base material by using a base paper having a basis weight of 100 g / m ² or more and 400 g / m ² or less and a thickness of 120 μm or more and 500 μm or less.

  Further, the hinge part 23 rotates the handle 22 around the hinge 23 by keeping the intermediate point of the hinge part 23 away from the straight line connecting both ends of the hinge part 23, thereby holding the handle 22 horizontally. At this time, the handle 22 can be deformed so as to be curved. Thereby, the rigidity of the handle 22 can be improved. The vertical distance from the straight line connecting both ends of the hinge portion 23 to the intermediate point of the hinge portion 23 is in the range of 1 mm to 10 mm (more preferably in the range of 3 mm to 8 mm), so that the handle 22 is rotated. While making it easy to do, the rigidity of the handle 22 can be improved.

  As described above, according to the container 1 according to the embodiment of the present invention, the plurality of first beads 24 are provided apart from the handle 22 formed to be rotatable on the body portion 21 of the sleeve 11 for the container, By providing the second bead 27 in the handle 22, the strength of the handle 22 and the container sleeve 11 can be improved. Further, the container 1 can be supported by the handle 22 by preventing the strength from being lowered even when a high-temperature content is put in the container body 10 or the content is heated.

  The present invention is not limited to the above embodiment. In the above-described example, the configuration in which the hinge portion 23 is formed in an arc shape has been described, but the configuration is not limited thereto. The hinge part 23 may be linear. Specifically, as shown in FIG. 7 by the blank 11A, the configuration of the container sleeve 11 according to the modification of the present invention is set so that the midpoint of the hinge portion 23A (third indentation 38A) is below the both ends of the hinge portion 23A. And the intermediate point and both ends may be connected by straight lines.

  Thus, the handle 22 can be stretched by making the hinge portion 23 </ b> A linear with respect to the cylindrical container sleeve 11. Further, the intermediate point of the hinge part 23A is displaced downward from both end parts of the hinge part 23A, and the intermediate point and both end parts are formed so as to be connected with straight lines, so that the handle 22 can be easily formed with a crease. The rigidity of 22 can be improved.

  Moreover, the structure which connects the both ends of the hinge part 23 with a straight line may be sufficient. By forming the both ends of the hinge portion 23 so as to be connected with a straight line, the handle 22 can be stretched.

  Moreover, in the example mentioned above, although the hinge part 23 demonstrated the structure arrange | positioned above the trunk | drum 21, ie, the edge part side which the container body 10 opens, it is not limited to this, The bottom part of the container body 10 is demonstrated. The structure arrange | positioned at the side may be sufficient. However, when the hinge part 23 is disposed on the bottom side of the container body 10, when the container body 10 is held with the handle 22, the handle 22 is described in a direction close to the container body 10, and the user's finger is placed in the container body 10. Since there exists a possibility of touching the body 10, it is preferable that the hinge part 23 is arrange | positioned upwards.

  Moreover, although the container sleeve 11 demonstrated the structure which gives water resistance to a paper base material in the example mentioned above, it is not limited to this. For example, as in Comparative Example 5 described above, the container sleeve 11 formed of only a paper base material having no water resistance may be used. Although the container sleeve 11 having such a configuration may be reduced in strength due to water absorption, the rigidity of the handle 22 can be improved by providing the second bead 27 on the handle 22. The container body 10 can be held by 22. Further, in use where the possibility of water absorption is low, the manufacturing cost of the container sleeve 11 can be reduced.

  In addition, the container sleeve 11 has the first bead 24 in the body portion 21 and the second bead 27 in the handle 22. However, the configuration is not limited thereto, and the second bead 27 is provided only in the handle 22. It may be a configuration.

  Further, in the above-described example, the configuration in which the hinge portion 23 is formed by the third indentation 38 has been described. However, the present invention is not limited to this. For example, the hinge portion 23 may be formed by a cut portion formed intermittently. Good. Further, the uneven portion of the present invention may not be a bead that extends linearly, but may be an uneven portion that has been subjected to uneven forming for improving rigidity. In addition, various modifications can be made without departing from the scope of the present invention.
