DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a container with a lid and a method of manufacturing the same according to the present invention will be described with reference to the drawings. A container with a lid for a cup noodle provided with a lid 2 for closing the portion will be described.

The container body 1 is formed by injection-molding a synthetic resin. For example, polypropylene, polyethylene, polystyrene, and their foamed resins are used. Unlike the conventional case, the upper end 1a of the container body 1 does not have a flange portion, and is located at a position lower than the upper end 1a by a predetermined amount at a substantially right angle (substantially outward) from the outer peripheral surface (side surface) of the container body 1. A (horizontally) projecting flange portion 3 is formed over the entire circumference. Here, the position below the upper end 1a by a predetermined amount refers to a range in which the lid 2 can be easily opened and closed, and a range in which the mouth does not feel uncomfortable when the mouth contacts the upper end 1a or a range in which the mouth does not contact the flange portion 3. The position is, for example, about 5 mm to 20 mm, preferably about 8 mm to 15 mm below the upper end 1a. The protrusion of the flange 3 is substantially uniform over the entire circumference. The lid 2 is adhered to the upper surface so as to be opened by heat sealing.

The lid 2 is formed by molding a plastic sheet into a sheet, and the back surface thereof is configured to be heat-fusible with the container body 1. Here, as the sheet forming, there are vacuum forming, pressure forming and the like. Also,
As the plastic sheet, a sheet of polypropylene, polyethylene, polystyrene, polyamide or the like can be adopted, and a sheet having a thickness of about 0.1 mm to 0.5 mm can be used. In addition to a single layer, a multi-layer sheet having an intermediate layer such as a gas barrier layer such as ethylene vinyl alcohol between both outer layers made of polypropylene or the like may be used. The back surface can be heat-fused with the container body 1. At this time, it is preferable to apply a sealant layer that can be easily peeled to the back surface as a heat-sealing layer. Further, the plastic sheet may be printed with a product name, a usage method, a design, and the like.

More specifically, the lid 2 includes a cover recess 4 that opens downward, and a flange portion 5 formed over the entire periphery at the lower end of the cover recess 4. Cover recess 4
Is configured to cover a region from the upper end portion 1a of the container body 1 to the flange portion 5 from outside. Specifically, the cover recess 4 is formed in a cylindrical shape with an upper end closed and a lower end opened, and has an inner diameter slightly larger than the outer diameter of the upper end 1 a of the container body 1.

The flange 5 of the lid 2 has a projection amount substantially equal to that of the flange 3 of the container body 1. When the lid 2 is put on the container body 1, the flange portion 3 of the container body 1 and the flange portion 5 of the lid 2 overlap each other. The flange portions 3 and 5 are bonded to each other by heat sealing.

A substantially entire surface of the flange portion 5 of the lid 2 is heat-sealed except for a portion near the base end. FIGS. 2 to 4 show the seal area S that has been heat-sealed, and FIGS. 3 and 4 show the seal area S by oblique lines and cross hatches. As will be described later, in the seal area S, a hatched portion is a portion to be opened, and a cross hatched portion is a portion that remains without being opened.

The container is opened by peeling off the flange 5 of the lid 2 bonded by heat sealing from the flange 3 of the container body 1 as described above. The idea is as follows.

That is, the lid 2 is formed with a separation line at the position near the boundary K between the cover recess 4 and the flange portion 5 when the cover is opened. Specifically, as shown in FIGS. 2 to 4, a perforation 6 as a separation line is provided at the base end of the flange portion 5.
Is engraved. The separating line is not limited to the perforated line 6 and may be any line that can be separated at the time of opening. If the perforated line 6 is not a through hole but a half cut, the container can be sealed tightly. Preferred.

The perforations 6 of the flange portion 5 are formed after the sheet is formed, for example, when cutting a plastic sheet into a predetermined shape. In addition, in more detail, in the present embodiment, it is a position near the inner edge portion S1 of the above-described seal region S, and is preferably slightly inside (the cover recess 4 side) of the seal region S. It is engraved at the position.

Further, the perforation 6 is formed along the boundary K in the remaining area except one area of the entire circumference of the flange portion 5. That is, the perforation 6 reaches the outer edge 5a of the flange 5 across the seal region S from the base end of the flange 5 outward at the start end 6a and the end 6b. In the flange portion 5 of the lid 2, an opening knob 7 for opening is extended outwardly, and a base end of the knob 7 has a starting end 6 a of a perforation 6.
Is provided. In addition, a region between the end 6b and the start 6a of the perforation 6 in the flange 5 is a region that is not separated by opening. The seal area S in this area is shown by a cross hatch in FIG. The cross-hatched seal area S remains in an adhered state even after opening.

The container with the lid 2 having the above-mentioned structure accommodates, for example, instant foods such as cup noodles and miso soup and confectionery, and is circulated after the lid 2 is heat-sealed. There is a possibility that dust or the like may adhere to the container due to the distribution process or display at the store, and the container may be stained.
Since it is covered with the cover concave portion 4 of the lid 2, there is no possibility that the drinking spout becomes dirty. As described above, since at least the region serving as the drinking mouth in the container body 1 is covered with the lid 2, the conventional shrink film that covers the entire container can be eliminated, and the manufacturing cost can be reduced. Further, usually, on the side surface of the container body 1, the design and display of the product are directly printed or attached by attaching a printed label, but these designs and display are covered with a shrink film. There is no adverse effect on appearance.

Further, the flange 3 of the container body 1 is not provided at the upper end 1a as in the prior art, but is provided at a position below the upper end 1a by a predetermined amount. The taste is also good.

Further, since the lid 2 is a molded lid formed by sheet molding, the lid 2 has a fixed shape, and therefore has the advantage that it can be recapped after opening. By recapping, when cooking using hot water such as instant cup noodles or miso soup, the hot water is less likely to be spilled, easy to carry, and the heat retention can be improved. However, as the lid 2, a flexible film lid made of a plastic film laminated with paper or aluminum foil or the like can be used by being bent from the upper end 1a of the container body 1 to the flange 3.

Further, the seal area S can be easily peeled off by picking up the knob portion 7 and pulling it upward. And
Since the perforation 6 is provided at the base end of the flange 5, the flange 5 can be cut off along the perforation 6 while pulling the knob piece 7, and can be easily opened.

Most of the flange portion 5 is cut off by this opening. However, since the perforation 6 is not formed on the seal region S but is formed inside the seal region S, the flange portion 5 is formed. The seal region S can be peeled over the entire width by the separation, and the vicinity of the inner edge portion S1 of the seal region S does not remain in a linear or band shape after opening.
In the present embodiment, the perforation 6 is formed on the flange 5 side in the vicinity of the boundary portion K between the cover concave portion 4 and the flange portion 5, but may be formed on the cover concave portion 4 side.
Further, in the case of being formed on the flange portion 5 side, the perforation 6 may slightly overlap the seal region S.

On the other hand, after opening, one area of the entire circumference of the flange portion 5 having a constant length in the circumferential direction (the area from the end 6b to the start 6a of the perforation 6) is adhered to the container body 1. Remains at. Therefore, as shown in FIG. 5, the cover recess 4 can be opened and closed up and down by using one area of the remaining flange portion 5 as a fulcrum, thereby further facilitating recapping and preventing the lid 2 from being lost. it can.

The cover recess 4 may be configured to be fitted to the container main body 1. With the fitted structure, the closed state of the lid 2 can be easily held during recapping, and the usability is further improved. .

In addition, the design of the container body 1 can be changed as appropriate, for example, the shape of the container body is also a square tube. For example, it is preferable that the outer edge portion 3a of the flange portion 3 of the container body 1 be bent downward as shown by a two-dot chain line in FIG. Further, the seal portion S may be configured so that there is no cross hatch portion, that is, the perforation 6 is provided over the entire circumference so that the lid 2 can be completely removed. Further, in the above embodiment, the container body 1 and the lid 2 are bonded by heat sealing. However, in addition to the heat sealing, bonding is performed using a peelable adhesive or bonding by ultrasonic welding. You may.

[0027]

As described above, the flange portion is lowered downward from the upper end of the container body by a predetermined amount, and the portion to be touched by the mouth after opening is covered with the lid from the outside to prevent the adhesion of dirt and dust in the region. Since the operation is performed with the lid, it is not necessary to cover the entire container with the shrink film as in the related art, so that the manufacturing cost can be reduced and the labor for opening the container can be reduced.
