DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described with reference to the drawings. 1 is a plan view of a container body of an instant food container, FIG. 2 is a sectional view taken along line AA in FIG. 1, FIG. 3 is a sectional view taken along line BB in FIG. 1, and FIG. FIG. 5 is a cross-sectional view, FIG. 5 is a plan view of a hot water cutting section, and FIG. 6 is a cross-sectional view showing a hot water cutting state.
[0008]
As shown in FIGS. 1 and 2, the instant food container according to the present invention includes an upper open container body 1 and a sheet-like lid 2. The container body 1 is formed by molding a foamed resin material such as foamed polystyrene, a non-foamed resin material, or a paper material. In the illustrated embodiment, the container body 1 is molded into a flat rectangular bowl shape. The container body 1 in the illustrated example is formed in a flat rectangular bowl shape having a rectangular bottom wall 3 and a peripheral wall 5 that is raised upward from the entire circumference of the bottom wall 3. A flange 6 is integrally formed to project outward from the entire periphery of the upper edge 5a of the opening of the peripheral wall 5 of the container body 1.
[0009]
Of the four sides of the flange 6, the two adjacent sides 6a and 6a are formed as wide flanges having a wide upper surface, while the other two adjacent sides 6b and 6b are the majority of the two sides. The width of the upper surface of the wide flange is narrower than the width of the upper surface of the wide flange, and the upper surfaces of the remaining portions of the two sides 6b, 6b are formed in a wide flange continuous with the wide flange. For example, the upper surface width of the wide portion of the flange 6 is about 14 mm, and the upper surface width of the narrow portion is about 10 mm. The narrow portion of the flange 6 is a place where a hot water pouring spout is created by the cooperative action with the lid 2.
[0010]
The corner portion where the two sides 6a and 6a of the flange 6 intersect is projected outward from the upper edge 5a of the opening. The width of the upper surface of the corner portion is narrow, and in this corner portion, the flange 6 On the inside, a hot water cutout 8 is formed. As shown in FIGS. 1 to 4, the hot water cut portion 8 includes a ridge portion 9 having the same height as the upper surface of the flange 6, and hot water cut grooves 10 and 10 located on both sides of the ridge portion 9. The hot water slicing grooves 10 and 10 are formed in the inner and outer directions of the container body 1. The inner end portion of the hot water cut groove 10 is formed so as to communicate with the inside of the container body 1, and the outer end portion is formed so as to be blocked inside the upper surface of the flange 6 and bonded to the upper surface of the flange 6. The lid 2 is hermetically sealed.
[0011]
As shown in FIGS. 1 and 3, two locations of the outer peripheral edge portion 61 (61 a) of the flange 6 where the hot water cut-out portion 8 is formed are inner than the outer peripheral edge portion 61 b of the other portion of the flange 6. It is biased to go in. In the two biased portions 61a and 61a, projecting pieces 62 projecting outward from a position lower than the upper surface of the flange 6 to a position aligned with the outer peripheral edge 61b of the other portion of the flange 6 are stepped. Is provided. In this embodiment, the above-described two biased portions 61 a and 61 a are formed at two locations spaced on both sides of the peak portion 9.
[0012]
In this way, the overhanging piece 62 is extended from the lower position of each of the lower portions of the biased portions 61a and 61a of the flange 6, and the outer peripheral edge of the protruding piece 62 is aligned with the outer peripheral edge of the other portion 61b. Thus, when a large number of container main bodies 1 are formed and separated into individual containers, the container main body 1 can be cut straight without any irregularities on the outermost peripheral edge of the flange 6 of the container main body 1, so that the separation work is Easy to do. However, the protruding piece 62 is not necessarily required, and the protruding piece 62 may be cut off after molding. Alternatively, the projecting piece 62 can be formed from the beginning without a shape.
[0013]
On the other hand, as shown in FIG. 2, the lid 2 has a printed layer 14 formed on the surface of a base 13 made of paper or synthetic resin, and a waterproof layer 15 made of aluminum foil or silica vapor deposition on the back of the base 13. The heat-sealable resin layer 16 is made of a laminated sheet having flexibility. The lid 2 is cut into a rectangular shape having a size substantially the same as the size around the outermost peripheral edge of the flat rectangular flange 6 of the container body 1.
[0014]
The container body 1 configured as described above contains, for example, fried noodles as the instant food 17, and a bag of fried noodle sauce, a bag sprinkle 18 and the like are attached to the instant food 17. Thereafter, the lid 2 is horizontally placed on the entire upper surface of the flange 6 of the container body 1, and a portion corresponding to the upper portion of the flange of the lid 2 is heated and pressed against the flange 6 by a heating press. As a result, the lid 2 is heat-sealed over the entire circumference of the upper surface of the flange 6 through the heat-sealable resin layer 16 so that the lid 2 can be peeled off again, and the upper opening of the container body 1 is sealed in a sealed manner.
[0015]
When the lid 2 is heat-sealed, the heating press pressurizes the entire outer peripheral area of the upper surface of the lid 2 with a uniform pressure from above, so that the width of the upper surface of the wide portion of the flange 6 is wide and the bonding area is widened. It is stronger than the upper surface of the narrow part, and there is a difference in adhesive strength between the adhesive strength in the wide part and the adhesive strength in the narrow part, and strongly adheres in the former wide part. Adhesive strength is weaker than that in narrow areas.
[0016]
Further, the lid 2 formed in a square shape having a size substantially the same as the size around the outermost peripheral edge of the flange 6 has a portion 2a corresponding to the upper side of the biased portion 61a of the flange 6 as shown in FIGS. Thus, it adhere | attaches in the state which protrudes outward from the upper direction of the bias location 61a. A part 2a of the outer peripheral edge of the lid 2 is aligned with the end of the other portion 2b, but protrudes outward from above the biased portion 61a. It becomes easy. In the case where the overhanging piece 62 is formed, a gap is formed between the overhanging piece 62 and the outer peripheral edge part 2a of the lid 2 as shown in FIG. Since the fingertip that pinches the portion 2a can be inserted, there is no problem in pinching the outer peripheral edge part 2a of the lid 2.
Further, as shown in FIG. 5, the corner portion of the lid 2 corresponding to the upper portion of the hot water cut portion 8 is preliminarily provided with a separation line 20 by a perforation or the like. It adheres so that it may be located over the other bias location 61a via the peak part 9 from the bias location 61a.
[0017]
The instant food container configured as described above has a narrow portion of the two sides 6b and 6b of the flange 6 prior to pouring hot water for unpacking the instant food 17 into the container body 1 during cooking before meals. The hot water pouring spout is opened by picking a part of the outer peripheral edge of the lid 2 corresponding to the upper part of the lid 2 and pulling it off as a starting point. At this time, since the adhesive force to the lid 2 is strong at the wide portion of the flange 6, in order to peel off the lid 2 at the wide portion of the flange 6, a force stronger than the previous peeling force is required. Become. For this reason, it is suppressed that the lid | cover 2 opens beyond the boundary part of the narrow part and the wide part of the flange 6, and it can prevent opening a hot water spout excessively more than necessary.
[0018]
From the hot water pouring spout thus opened, a bag of fried noodles and a bag sprinkle 18 are taken out, and then hot water is poured.
After pouring hot water, the hot water spout is temporarily closed with the lid 2 until the instant food 17 is unwound, but at this time, the lid 2 is opened by a predetermined opening amount without being opened too much, The hot water spout can be easily and sufficiently closed.
[0019]
After unpacking the instant food 17, drain the hot water. At the time of this hot water cutting, the outer peripheral edge part 2a of the lid 2 protruding outward from the biased portion 61a of the outer peripheral edge portion 61 of the flange 6 in the hot water cutting part 8 is pinched and peeled along the cutting line 20 in FIG. As shown, the hot water outlet 19 is opened. At this time, since the outer peripheral edge part 2a of the lid 2 protrudes outward from above the biased portion 61a of the flange 6, it can be easily pinched, and a tongue piece is formed on the outer peripheral edge part of the lid 2. The lid 2 can be easily peeled off even if the tab portion is not projecting. At that time, the hot water cut opening 19 opened by peeling the lid 2 along the separation line 20 is opened and opened by a predetermined opening amount that opens the outer end portion of the hot water cut groove 10 and covers the upper end of the inner end portion. The instant food 17 can be prevented from flowing together with hot water from the hot water groove 10 when the hot water is cut.
Note that the lid 2 can be folded in a valley fold at the parting line 20 without being separated along the parting line 20.
[0020]
In the above-described embodiment, a part in the circumferential direction of the outer peripheral edge 61 of the flange 6 of the hot water cutting section 8 is biased inwardly from the other flange outer peripheral edge 61b, and outward from above the biased portion 61a. The outer peripheral edge part 2a of the protruding lid 2 is configured to be easily pinched, but instead of this, as shown in FIG. A biased portion 61a that is biased inwardly may be formed. In such a case, the outer peripheral edge of the corner portion of the lid 2 protrudes outward from above the biased portion 61a so that it can be easily pinched. You can also Also in this case, a protruding piece 62 that protrudes outward from a position lower than the upper surface of the flange 6 to a position aligned with the outer peripheral edge 61 of the flange 6 located on both sides of the biased position 61a is provided in the biased position 61a. The overhanging piece 62 can be left or cut off.
[0021]
Moreover, in the said Example, in order to produce the adhesive strength difference with respect to the flange 6 of the lid | cover 2, although the wide part and the narrow part were provided in the flange 6, this invention is the same width | variety over the perimeter of this. The present invention can be similarly applied to the case where it is formed.
The container body 1 is not limited to the one formed into a planar rectangle, but can be similarly applied to one formed into a planar square or other polygons, or one formed into a circle or an ellipse. As an adhesive means for the lid 2, it is possible to use an adhesive having food safety instead of the heat fusion of the above embodiment.
[0022]
【The invention's effect】
According to the present invention, at the time of hot water cutting, the hot water cutting opening can be easily opened by an appropriate opening amount for hot water cutting by peeling off a part of the outer peripheral edge of the lid along the separation line.
