Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container for instant foods such as fried noodles, spaghetti, etc. that need to be quickly drained after a predetermined time (time for making instant foods edible) after pouring hot water during eating. In more detail, the sealing of the container with the container, the safety and quickness when draining the hot water, the ease of forming the drainage (easy opening), and the lid of the instant food container having easy disposal, especially The present invention relates to a lid for an instant noodle container having a hot water discharge function.
[0002]
[Prior art]
Conventionally, as a cup container for instant foods that require pouring hot water during eating, such as fried noodles, spaghetti, etc., and after a certain period of time, it is generally volatile such as butane and pentane on polystyrene resin particles A foam resin bead cup container body formed by foaming expandable resin particles (beads) containing a foaming agent, and a plastic resin lid material having a drain outlet on the outer periphery produced by sheet molding. Covered ones are widely used.
[0003]
On the other hand, an example of using a paper lid is disclosed in Japanese Utility Model Publication No. 61-3810. The lid material disclosed in this official gazette is cut into a blank sheet having the same outer shape as the opening of the container main body, which is made of paper as a base material and is formed with a hot water outlet that can be peeled off by a knob portion. There was an instant food container sealed at the opening.
[0004]
[Problems to be solved by the invention]
However, many of the conventional plastic resin lid materials are simply put on the cup container body made of foam beads as described above, and provided on the flange portion on the outer periphery of the plastic resin lid material. Most of them are engaged by a groove having a protrusion for engagement, and there is a problem that there is no sealing performance.
[0005]
Further, as shown in FIG. 5A, the conventional plastic resin lid member is provided with claw portions for forming hot water outlets at several locations by cutting into opposite positions, and the claw portions are raised. Thus, a hot water outlet is formed. However, since the claw portion can only be formed on a part of the flange, it is not possible to form a large number of hot water outlets, requiring a lot of time for hot water to be discharged, and the hot water outlet is blocked by the contents. In this case, there is a problem that more time is required for draining hot water. Further, when the claw portion is erected to form the hot water outlet, there is a possibility that foreign matter may be mixed in the cup container, for example, the claw portion is broken.
[0006]
Furthermore, since most of the conventional plastic resin lids are sheet-molded products, they are bulky during transportation or storage and appear bulky even when covered with a cup container body for instant foods, which is poor in appearance. The problem has arisen.
[0007]
In addition, since the conventional plastic resin lid and cup container are engaged only by a groove portion having an engaging protrusion provided on the flange portion on the outer periphery of the lid material, if the oil is cut off, During hot water, the contents and the weight of the hot water may cause the engagement to disengage, causing the contents to pop out and burn your hands, etc. at that time. I had to hot water.
[0008]
In addition, since most of the conventional plastic resin lids are sheet-molded products, there is a possibility that there will be a problem in terms of disposal in connection with recent environmental problems.
[0009]
On the other hand, the lid material disclosed in the aforementioned Japanese Utility Model Publication No. 61-3810 is a lid material made of a laminate in which polyethylene, aluminum foil, etc. are laminated with paper as a base material, as shown in FIG. 5 (B). Then, in an instant food container in which the lid is sealed to the container body, a half-cut for peeling connecting the base ends of the knob is obtained by pinching the knob provided on the lid and pulling it upward. As a trigger, a hot water outlet is formed by peeling off a part of the lid. As described above, the cover material based on paper has a sealing property as compared with the one made of plastic resin as described above, is not bulky during transportation or storage, is easy to manufacture, and is disposed of by disposal. It is also excellent in terms of ecology. However, when the peeling half cut is provided in such a manner as to connect the both ends of the base of the knob, the lid member seals the container body when the knob is pulled upward to open the hot water outlet. For this reason, there is a possibility that the knob portion is broken by the use of the peeling half-cut portion, which makes it difficult to open the hot water outlet.
[0010]
Further, as shown in FIG. 5 (B), the hot water outlet opening knob is provided at a position facing the opening knob, that is, near the center of the outer periphery of the peeling region. It is necessary to open the drainage port by peeling it while applying force so that it spreads in many directions centering on the knob for opening the drainage port provided at the center. In some cases, there was a risk of breakage from the knob or the like in the middle of the opening.
[0011]
By the way, the object of the present invention, in particular, fried noodles, spaghetti, and the like is to pour hot water at the time of eating, and after a predetermined time has passed, in the lid of a container for instant food that requires drainage work, sealing with the container, Safety food and safety when draining hot water, ease of forming hot water outlet (easy opening), and easy food container lid, especially instant noodle container lid with drainage function Is to provide.
