The first fitting portion 41 is inserted into the second fitting portion 42, and at that time, the side surface of the bulging portion 41a is pressed against the inner surface of the second fitting portion 42, whereby the second fitting portion 42 is second. The first fitting portion 41 is fitted to the fitting portion 42 so that it can be coupled to each other. That is, the second fitting portion 42 has a shape in which the first fitting portion 41 can be fitted inside and bonded to each other.

As shown in FIGS. 6 and 7, in the container 1, the first handle piece portion 21 and the second handle piece portion 22 are bent upward from the opening 6 starting from the crease 45, and the first fitting portion 41 and the first fitting portion 41 and the second handle portion 22 are bent. The two fitting portions 42 can be fitted and joined to each other. In this state, the first handle piece 21 and the second handle piece 22 are united to form one arch-shaped handle 23 on the upper side of the opening 6.

When the handle 23 is formed, as shown in the enlarged view shown in FIG. 7, the rib portion 50 of the first handle piece portion 21 and the rib portion 50 of the second handle piece portion 22 have the handle pieces 21 and 22 facing each other. It protrudes to the opposite side (outside) from the side (inside). As shown in FIG. 4, this is composed of a bent portion 51 in which the rib portion 50 bends downward while the first handle piece portion 21 and the second handle piece portion 22 are substantially parallel to the first flange portion 10. Because it is.

The rib portion 50 is provided between both ends of the handle 23, and the handle piece is also provided in the central portion of the handle 23 above the first fitting portion 41 and the second fitting portion 42 in the same manner as the other portions. The portions 21 and 22 project to the opposite side (outside) from the side facing each other.

Next, the configuration of the lid 2 will be described. As shown in FIG. 2, the lid 2 is arranged inside the first slit portion 31 and the second slit portion 32 to close the opening 6, and the plan view is along the edge 6a of the opening 6 of the container 1. It is formed in a rectangular shape. As shown in FIG. 4, the lid 2 is provided on a flat plate-shaped lid main body 61, a groove-shaped fitting portion 62 formed along the outer peripheral edge of the lid main body 61, and an outer peripheral edge of the fitting portion 62. A flange portion 63 formed along the line is provided.

The fitting portion 62 is detachably fitted to the upper side wall portion 8b of the container main body portion 5. The fitting portion 62 has an inner wall portion 62a formed by bending downward at a substantially right angle from the outer peripheral edge of the lid main body portion 61, and an outer wall formed substantially parallel to the inner wall portion 62a on the outside of the inner wall portion 62a. It has a portion 62b and a bottom portion 62c that connects the lower ends of the inner wall portion 62a and the outer wall portion 62b. The outer wall portion 62b is formed so as to slightly expand outward as it goes downward. The flange portion 63 is formed so as to be bent at a substantially right angle from the upper end of the outer wall portion 62b and project outward.

As shown in FIG. 4, when the lid 2 is inserted into the opening 6 of the container 1 of the fitting portion 62, the outer wall portion 62b elastically contacts the inner surface of the upper side wall portion 8b, and the bottom portion 62c has a stepped surface 8d. The flange portion 63 abuts on the upper surface 10a of the first flange portion 10. The outer wall portion 62b elastically contacts the inner surface of the upper side wall portion 8b, so that the lid 2 is detachably fitted inside the opening 6 of the container 1. As described above, both the outer wall portion 62b and the upper side wall portion 8b are formed so as to slightly expand outward as they go downward. Therefore, the outer wall portion 62b is appropriately caught on the upper side wall portion 8b, and the lid 2 is in a state of being difficult to come off from the opening 6.

In the container 1, the food as described above is stored in the food storage section 9, and the container 1 is supplied to the user in a state where the opening 6 is closed by the lid 2 and the food is sealed. As shown in FIGS. 6 and 7, the user is formed by fitting the first fitting portion 41 of the first handle piece portion 21 and the second fitting portion 42 of the second handle piece portion 22 to each other. The handle 23 can be grasped and the food can be carried together with the container 1.

The above is the configuration of the container 1 and the lid 2 according to the present embodiment, and then an example of the manufacturing method of the container 1 will be described. Here, an example of the method for manufacturing the container 1 will be described with reference to FIGS. 8 and 9, but the method can also be applied to the lid 2.

In the manufacturing method of the container 1, first, as shown in FIG. 8, a molding step of press-molding a sheet S made of a thermoplastic resin such as polypropylene into the shape of the container 1 by a mold 100 is performed. The mold 100 includes a male upper mold 101 that forms the upper surface of the container 1 and a female lower mold 102 that forms the lower surface of the container 1. A sheet S softened by heating to about 300 ° C. is placed between the upper die 101 and the lower die 102, and the sheet S is press-molded by the upper die 101 and the lower die 102 at a predetermined pressure. After press molding, the sheet S is cooled and cured while maintaining the pressed state by the die 100.

In the present embodiment, vacuum compressed air molding, which is a method of press molding, is preferably adopted. In the vacuum pressure air forming, the air between the mold 100 and the sheet S is sucked and the sheet S is adsorbed on the upper mold 101 and the lower mold 102, and at the same time, compressed air is sent to make the upper mold 101 and the lower mold 102 the sheet S. The sheet S is press-molded by pressing against.

After the molding step, as shown in FIG. 9, the outermost peripheral edge of the container 1, that is, the first one, is formed by the cutting member 200 made of a Thomson blade type on the sheet S having a shape similar to that of the container 1 that has been press-molded and cooled. A cutting step of forming the outer peripheral edge of the flange portion 10 and the first slit portion 31 and the second slit portion 32 is performed. The cutting member 200 is a pair of an annular first blade portion 201 for punching the outer peripheral portion of the sheet S and a pair of the first slit portion 31 and the second slit portion 32 for punching a predetermined portion of the sheet S on the lower surface of the board 205. The second blade portion 202 having a semicircular arc shape is provided.

As shown in FIG. 9, in the cutting step, the cutting member 200 is moved back and forth with respect to the sheet S from the state where the portion corresponding to the second flange portion 20 of the sheet S is received by the lower plate 206, and the first blade portion 201 and the first blade portion 201 and the first. The sheet S is punched out by the two-blade portion 202. As a result, the outer peripheral edge of the first flange portion 10 and the first slit portion 31 and the second slit portion 32 are formed to obtain the container 1.

In the above manufacturing method, a large number of containers 1 can be continuously mass-produced by sequentially performing a molding step and a cutting step on a manufacturing line.

The above is the configuration and manufacturing method of the container 1 according to the embodiment, and the effects produced by the container 1 will be described below.

The container 1 according to the present embodiment is formed on the outer side of the container main body portion 5 having an opening 6 that opens upward, the first flange portion 10 formed on the outside of the opening 6, and the first flange portion 10. The container body between the second flange portion 20, the first slit portion 31 formed between the first flange portion 10 and the second flange portion 20, and the first flange portion 10 and the second flange portion 20. A second slit portion 32 formed at a position opposite to the first slit portion 31 with the portion 5 interposed therebetween is provided, and the second flange portion 20 has a rib portion 50 projecting downward on the outer peripheral edge thereof. ..

In the container 1, the second flange portion 20 is separated into a first slit portion 31 side and a second slit portion 32 side to form a first handle piece portion 21 and a second handle piece portion 22, and these handle piece portions are formed. When the 21 and 22 are combined above the opening 6 of the container body 5, the handle 23 is formed. Since the rib portion 50 is formed on the outer peripheral edge of the second flange portion 20 constituting the handle 23 in this way, the rib effect that the rigidity of the handle 23 is improved can be obtained. Therefore, the handle 23 is prevented from being bent and deformed, and the container 1 can be stably carried when the handle 23 is grasped and carried. Further, when the first handle piece portion 21 and the second handle piece portion 22 are used as the handle 23, the rib portions 50 of the handle piece portions 21 and 22 project outward as shown in FIG. Fingers hang on the portion 50 to prevent slipping, making it easy to grip. Therefore, the possibility of inadvertently dropping the container 1 is reduced. As a result, even when relatively heavy food such as oden is stored, when the handle 23 is grasped and the container 1 is carried, the handle 23 is not easily deformed and the container 1 is easily carried. As a result, the food can be stably carried without putting the container 1 in a bag or placing it on a tray. According to the container 1 according to the present embodiment, the function of the handle 23 is sufficiently fulfilled, and food can be carried without using a carrier such as a bag.

In the container 1 according to the present embodiment, the second flange portion 20 is the first handle piece portion 21 of the outer portion of the first slit portion 31 and the outer portion of the second slit portion 32 of the second flange portion 20. 2 Handle piece portion 22 and the rib portion 50, the first handle piece portion 21 and the root portion of the second handle piece portion 22 are included, and the first handle piece portion 21 and the second handle piece 22 are formed. At the base of the portion 22, a crease 45 extending in a direction intersecting the outer peripheral edge and allowing the first handle piece portion 21 and the second handle piece portion 22 to bend upward of the opening 6 is provided. Each is formed.

As a result, the first handle piece portion 21 and the second handle piece portion 22 can be easily bent at the crease 45 even if the rib portion 50 is formed on the outer peripheral edge.

The container 1 according to the present embodiment is provided in the central portion of the first fitting portion 41 provided in the central portion of the first handle piece portion 21 and the central portion of the second handle piece portion 22, and is fitted in the first fitting portion 41. A second fitting portion 42 having a shape that allows fitting is further provided, and in a state where the second fitting portion 42 is fitted to the first fitting portion 41, the first handle piece portion 21 and the second handle piece portion 22 are provided. Form a handle 23 located on the upper side of the opening 6 in a state of facing each other, and at least in the central portion of the handle 23, the rib portion 50 of the first handle piece portion 21 and the rib portion of the second handle piece portion 21. The portion 50 projects to the side (outside) opposite to the side where the first handle piece portion 21 and the second handle piece portion 22 face each other.

As a result, the first fitting portion 41 and the second fitting portion 42 are fitted, and the first handle piece portion 21 and the second handle piece portion 22 are not separated, and the handle 23 is held.

The food in the container 1 may be eaten by heating the whole container 1 with a cooking utensil such as a microwave oven. At that time, the container 1 is also heated, but the first handle piece portion 21 and the second handle piece portion 22 are separated from the first flange portion 10 by the first slit portion 31 and the second slit portion 32, respectively. Therefore, the heat of the food is not easily transferred to the first handle piece 21 and the second handle piece 22, and the food is easy to grip. Therefore, when heating the container 1, by heating the handle 23 as it is from the formed state, it is possible to easily carry the container 1 by grasping the handle 23 which has not been heated to a high temperature after heating.

Normally, when the handle 23 is gripped and the container 1 is carried, the central portion of the handle 23 is gripped. In the present embodiment, since the rib portion 50 is provided at the central portion of the handle 23, the rib portion 50 can be reliably carried by hanging a finger on the rib portion 50. Further, since the first fitting portion 41 and the second fitting portion 42 are arranged below the rib portion 50 in the central portion, the first fitting portion 41 and the second fitting portion 41 and the second fitting portion 42 are fitted together with the rib portion 50. Hook a finger on the portion 42 to grab the handle 23. By hooking the fingers on the first fitting portion 41 and the second fitting portion 42 together with the rib portion 50, the effect of suppressing the fall is increased.

In the container 1 according to the present embodiment, the upper and lower surfaces (upper surface 10a and lower surface 10b) of the first flange portion 10 and the upper and lower surfaces (upper surface 20a and lower surface 20b) of the second flange portion 20 are formed on the same plane. Then, the lid 2 that closes the opening 6 is detachably fitted inside the opening 6 of the container body 5.

As a result, there is no step between the first flange portion 10 and the second flange portion 20, so that when the container 1 is integrally molded using the mold 100 as described above, the mold 100 has a simple structure. It is possible to reduce the cost. Further, if there is no step between the first flange portion 10 and the second flange portion 20 and the second flange portion 20 is continuously flat, it is difficult to attach and detach the lid that closes the opening 6. However, in the present embodiment, since the lid 2 is detachably fitted inside the opening 6, there is no step between the first flange portion 10 and the second flange portion 20, and the lid 2 is flat and continuous. However, the opening 6 can be reliably closed by the lid 2, and the lid 2 can be detachably attached to the opening 6. Further, the container 1 can hygienically store food by closing the opening 6 with the lid 2.

A first fitting portion 41 is formed in the central portion of the first handle piece portion 21, and a second fitting portion 42 having a shape in which the first fitting portion 41 is fitted in the central portion of the first handle piece portion 21. Is formed.

As shown in FIG. 11, a rib portion 50 that bends downward is formed on the outer peripheral edge of the second flange portion 20 over the entire circumference. The rib portion 50 includes a bent portion 51 that bends downward on the outer peripheral edge of the second flange portion 20.

The container 3 according to the first modification shown in FIGS. 10 and 11 has the same effect as the container 1 of the above embodiment. Further, according to the container 3, various circular foods can be efficiently stored in the food storage portion 9 having a circular plan view without taking up wasted space.

(Second modification)
FIG. 12 shows a second modification in which a part of the container 1 of the above embodiment is deformed. In the container 1 of the second modification, the rib portion 50 is formed by excluding at least the root portion of the first handle piece portion 21 and the second handle piece portion 22 from the outer peripheral edge of the second flange portion 20. At the same time, no crease 45 is formed at the root portion thereof. In the second modification, the rib portion 50 is formed only on the outer peripheral edge of the first handle piece portion 21 and the second handle piece portion 22 on the long side 5b side, and is formed on the outer peripheral edge on the short side 5a side. Not. The second modification differs from the container 1 of the above embodiment only in these points, and is the same in other configurations.

In the container 1 of the second modification, since the rib portion 50 is not formed at the root portion of the first handle piece portion 21 and the second handle piece portion 22, the root portion thereof can be easily curved upward. Can be done. Therefore, even if the crease 45 is not formed, the first handle piece 21 and the second handle piece 22 are curved above the opening 6 of the container 1 so that the central portions are brought close to each other so that the first fitting is first fitted. The joint portion 41 and the second fitting portion 42 can be fitted to each other to form the handle 23 of the above embodiment.

In the container 1 according to the second modification, the rib portion 50 is formed by excluding at least the root portion of the first handle piece portion 21 and the second handle piece portion 22 from the outer peripheral edge of the second flange portion 20. At the same time, the crease 45 is not formed at the root portion thereof.

As a result, the first handle piece 21 and the second handle piece 22 are curved above the opening 6 to fit the first fitting portion 41 and the second fitting portion 42 to each other, thereby fitting the handle 23. Can be formed. Further, when the state of the handle 23 is released, the first handle piece portion 21 and the second handle piece portion 22 are quickly separated and move so as to elastically return to their original positions. This is because there are no creases 45 at the roots of the first handle piece 21 and the second handle piece 22, and it is difficult for creases to form even when curved. Therefore, when the food is taken out from the food storage part 9, the state of the handle 23 is released so that the first handle piece 21 and the second handle piece 22 can smoothly take out the food without getting in the way. ..

Further, since the first handle piece portion 21 and the second handle piece portion 22 have the rib portion 50 on the long side 5b side, the rigidity is ensured. Therefore, as in the above embodiment, when the handle 23 is grasped and the container 1 is carried, the effect that the container 1 can be carried stably is obtained.

The present invention is not limited to the embodiment of the above embodiment, and can be appropriately modified. For example, the rib portion 50 has a configuration including a bent portion 51 that bends downward, and also has a form that protrudes downward from the outer peripheral edge of the second flange portion 20 and has a certain width (from the thickness of the second flange portion 20). The cross-sectional shape having a large width) may be composed of ridges such as an anti-arc shape or a rectangular shape.

The first fitting portion 41 and the second fitting portion 42 formed on the first handle piece portion 21 and the second handle piece portion 22, respectively, may be omitted. In that case, by grasping the first handle piece 21 and the second handle piece 22 bent upward of the opening 6, the handle 23 by the first handle piece 21 and the second handle piece 22 is formed. ..

As the lid 2, in addition to the one made of elastic resin, a film called an easy peel film made of polyethylene, polypropylene or the like applied to wrapping or the like of a packaging material may be used. The lid made of this kind of film is detachably attached to the upper surface 10a of the first flange portion 10, for example, by a method such as welding or adhesion.
