Description

  The present invention relates to a hot water lid member used as a package for instant food to be cooked by hot water after pouring, such as instant fried noodles and spaghetti.

  Conventionally, as a hot water lid material, a base material is constituted by a laminated film, and a surface material covering the base material is a paper layer having a surface coat layer mainly composed of kaolin, calcium carbonate, latex, and casein. The base material and the surface material are laminated so as to be peelable with an adhesive resin such as polyethylene by interposing the surface coat layer as a release layer, and the peeling material provided on the outer edge is pulled to base the surface material. It is known that when peeled off from the material, the inner part of the hot-cut hole forming half cut formed from the substrate side is removed along with the surface material so that the hot-water cut hole appears ( For example, see Patent Document 1).

JP 2002-96879 A

  By the way, the above-mentioned conventional hot water lid member is not a big problem when the shape of the hot water cut hole defined by the half cut for hot water cut hole formation is circular, but when the hot water cut hole has an elongated shape, When the material is peeled off, the inner portion of the hot water cut hole forming half cut may not be accompanied by the surface material and may remain on the base material side, making it impossible to open the hot water cut hole. Also, if the inner part of the hot-cut hole forming half cut does not accompany the surface material and remains on the base material side, the part falls into the container with a slight force and mixes with the contents. This is not preferable for hygiene purposes, and there is a problem that the design of the hot water hole is limited.

  The present invention has been made in view of the above problems, and even when the shape of the hot water cut hole defined by the hot cut hole forming half cut is an elongated shape, the hot water cut hole forming half is formed when the surface material is peeled off. The purpose is to ensure that the inner part of the cut can be removed along with the surface material so that the hot water hole can be exposed, and the degree of freedom in designing the hot water hole can be increased. .

  In the present invention, when the shape of the hot water cut hole defined by the hot water cut hole forming half cut is an elongated shape, when the surface material is peeled in the length direction of the hot water cut hole, the inner portion of the hot water cut hole forming half cut is While it will be separated from the base material side while being greatly bent, it will be peeled off from the surface material by the elastic repulsive force and will remain on the base material side, whereas if the surface material is peeled in the width direction of the hot water cutting hole, This is achieved by finding that the inner part of the cut hole forming half cut can be reliably removed by being separated from the base material side without being greatly bent.

  That is, the present invention pulls the peeling tab provided on the outer edge, and peels the surface material covering the base material from the base material, so that the inner side of the half cut for hot water cut hole formation formed from the base material side. In the hot water lid member that reveals the hot water hole by removing the part along with the surface material, the shape of the hot water hole defined by the hot water hole forming half-cut is an elongated shape, and the peeling tab However, the present invention provides a hot water lid member characterized by being provided at the outer edge in the width direction of the hot water hole defined by the half cut for hot water hole formation.

Further, the present invention is characterized in that the cutting half-cut that allows the surface material covering the base material in the region where the hot-cut hole forming half-cut is formed to be separated from the surface material in the other region can be peeled across the surface material. The hot water cut hole forming half-cut is formed so that the length direction of the hot water cut hole defined by the hot water cut hole forming half cut is directed in a direction crossing the separating half cut. The peeling tab is provided adjacent to one end of the cutting half-cut,
A half-cut for cutting is formed across the surface material so that the surface material covering the base material in the region where the half-cut hole forming half-cut is formed can be separated from the surface material in other regions. The cut hole forming half cut is formed with the length direction of the hot water cut hole defined by the hot water cut hole forming half cut being substantially parallel to the cutting half cut, and the peeling tab is formed with the hot water cut hole. It is provided at a position facing the separation half-cut across the hole-forming half-cut,
A half-cut for cutting is formed by separating the surface material into a tongue-like shape that separates the surface material covering the base material in the region where the hot-cut hole forming half-cut is formed from the surface material in the other region. And a stripping tab is provided on the outer edge of the tongue-shaped segmental area, and the half-cut forming half-cut peels off the width direction of the cut-off hole defined by the half-cut forming half-cut Being formed towards the tab for

Is included as a preferred embodiment thereof.

  According to the present invention, even if the shape of the hot water cut hole defined by the hot water cut hole forming half cut is an elongated shape, the inner portion of the hot water cut hole forming half cut is reliably used as the surface material when the surface material is peeled off. Since it is possible to remove the hot water cut hole along with it, it is possible to adopt an elongated shape other than a circle as the shape of the hot water cut hole and to increase the degree of freedom in designing the hot water cut hole It is.

  First, the 1st example of the hot water lid material of this invention is demonstrated based on FIGS. 1-3.

  FIG. 1 is a plan view of an example of an instant food package using a hot water lid according to a first example of the present invention, FIG. 2 is a side view of the instant food package shown in FIG. 1, and FIG. 3 is shown in FIG. It is a top view in the middle stage which exfoliates a part of surface material of the hot water lid member and makes a hot water hole appear.

  As shown in FIGS. 1 and 2, the hot water lid 1 is heat-sealed around the periphery of the opening of the container 2 to seal the inside of the container 2 containing instant food (not shown). Moreover, the hot water lid material 1 is comprised with the laminated body which covered the base material 3 and laminated | stacked the surface material 4 so that peeling was possible, as FIG. 2 shows.

  One edge of the hot water lid member 1 extends outward from the container 2 to form an opening tab 5. The unsealing tab 5 is for partially peeling the hot water lid member 1 from the container 1 in order to pour hot water into the container 1, and the base material 3 and the surface material constituting the hot water lid member 1. It is formed by projecting a part of the outer edge of 4 outward from the outer edge of the container 1.

  A hot water cut hole forming half cut 6 is formed in a region offset from the edge on the side opposite to the opening tab 5. The hot water cut hole forming half cut 6 defines the hot water cut hole 7 (see FIG. 3) which appears by removing the inner portion thereof, and the base material 1 from the base material 1 side shown in FIG. Is formed.

  The hot water cut hole forming half cut 6 shown in the figure defines an oval hot water cut hole 7 (see FIG. 3) having parallel sides and arcuate ends. As long as the shape of the hot water cutting hole 7 defined by the hole forming half-cut 6 is an elongated shape, it may be rectangular or elliptical. However, the oval shape is preferable because the inner portion of the hot-cut hole forming half-cut 6 is easily pulled out from the base material 3 side when the surface material 4 is peeled off.

  Between the surface material 4 that covers the base material 3 in the region where the half-cutting hole forming half-cut 6 is formed and the surface material 4 in other regions, the surface material 4 is crossed, for example, perforations. A half-cut 8 for separation such as intermittent slits and continuous slits is formed. This separation half cut 8 is for separating the surface material 4 covering the base material 3 in the region where the hot water cut hole forming half cut 6 is formed from the surface material 4 in the other region so as to be peeled off. , Formed from the surface material 4 side. The separating half cut 8 is not essential, and may be omitted, and the surface material 4 may be peeled over the entire region to reveal the hot water cut hole 7 (see FIG. 3). . However, if the separation half-cut 8 is provided, the peeling region of the surface material 4 for exposing the hot-water cutting hole 7 can be minimized, and the peeling work is facilitated and applied to the surface. This is preferable because the printed display can be left.

  A peeling tab 9 is formed adjacent to one end of the separating half cut 8. The peeling tab 9 is provided as a clue when peeling the surface material 4, and the peeling tab 9 in this example is adjacent to one end of the separating half cut 8, It is provided by forming the notch 10 in the outer edge. Further, the hot water cut hole forming half cut 6 has a direction in which the length direction of the hot water cut hole 7 (see FIG. 3) defined by the hot water cut hole forming half cut 6 intersects with the cutting half cut 8 (this book). In the example, the peeling tab 9 is formed at the outer edge in the width direction of the hot water cut hole 7 defined by the hot water cut hole forming half cut 6. is doing.

  Next, the procedure for using the instant food package of this example will be described with reference to FIG.

  There are two usage procedures. The first is to pull the opening tab 5, partially peel off the hot water lid 1 from the container 2, open the mouth, and pour hot water into the container 2. After placing, the surface material 4 on the half cut 6 for hot water cut hole formation is peeled off from the peeling tab 9 so that the hot water cut hole 7 appears. Second, in the same manner as described above, the hot water lid 1 is partially peeled off from the container 2 to open the mouth, and after the hot water hole 7 is exposed, the hot water is poured into the container 2 and required. It is a procedure that takes time. In particular, the latter is a procedure in which the surface material 4 is peeled off before the hot water is poured into the container 2, so that the hot water is not easily spilled when the surface material 4 is peeled off.

  In any of the above procedures, after a lapse of a predetermined time, the container 2 is tilted toward the hot water cut-out hole 7 side to discharge hot water in the container 2, and then the hot water cover material 1 is completely removed for eating. It is what is done.

  The peeling of the surface material 4 in this example is performed by causing the surface material 4 of the peeling tab 9 portion to be pulled from the cutout portion 10 side. Since the peeling tab 9 that is the starting point of the peeling is provided at the outer edge in the width direction of the hot water cut hole 7 defined by the hot water cut hole forming half cut 6, the peeling of the surface material 4 is performed in the hot water cut hole. The forming half cut 6 is performed from the width direction of the hot water cut hole 7, and the inner portion of the hot water cut hole forming half cut 6 is separated from the base material 3 side without being greatly bent, so The cut hole 7 can be revealed. In particular, in this example, the separation half-cut 8 is provided, and the peeling tab 9 is provided adjacent thereto, so that a part of the peeled surface material 4 is along the separation half-cut 8. Therefore, the force that pulls the surface material 4 of the peeling tab 9 portion that is caused is easily guided in a direction parallel to the separation half-cut 8, and the hot water defined by the half-cut-hole forming half-cut 6 Separation from the width direction of the cut hole 7 is more easily performed.

  Next, the 2nd example of the hot water lid material of this invention is demonstrated based on FIGS.

  FIG. 4 is a plan view of an example of an instant food package using a hot water lid according to the second example of the present invention, FIG. 5 is a side view of the instant food package shown in FIG. 4, and FIG. 6 is shown in FIG. 3 is a plan view in the middle of peeling off a part of the surface material of the hot water lid member to reveal the hot water hole, in which the same reference numerals as in FIGS. 1 to 3 indicate the same members or parts .

  As shown in FIGS. 4 and 5, the hot water cut hole forming half cut 6 of the present example is provided substantially in parallel with the separating half cut 8. Further, the peeling tab 9 is located at the outer edge in the width direction of the hot water cut hole 7 (see FIG. 6) defined by the hot water cut hole forming half cut 6. Specifically, as shown in FIGS. 1 and 2, the peeling tab 9 of the present example has a base material 3 at a position facing the separating half cut 8 with the hot water hole forming half cut 6 interposed therebetween. The surface material 4 is partially protruded outward from the outer edge of the container 1, while the peeling start half cut 11 is formed from the base material 3 side across the base of the protruding portion. ing. This peeling start half-cut 11 is for separating the base material 3 of the peeling tab 9 portion so that the surface material 4 can be peeled from the base material 3 by picking and pulling the whole peeling tab 9 portion. , Formed through the substrate 3.

  As shown in FIG. 6, the peeling of the surface material 4 in this example is performed from the peeling tab 9 toward the separating half cut 8, and thus the hot water cutting hole 7 defined by the hot water cutting hole forming half cut 6. Since the inner part of the half cut 6 for hot water cut hole formation is separated from the base material 3 side before it is greatly bent, this is surely removed and the hot water cut hole 7 is removed. Can appear. In particular, in the case of this example, it is easy to shorten the distance from the peeling tab 9 to the hot water cut hole forming half cut 6, and thus it is easy to prevent a deviation in the peeling direction.

  Furthermore, the 3rd example of the hot water lid material of this invention is demonstrated based on FIGS.

  7 is a plan view of an example of an instant food package using a hot water lid according to the third example of the present invention, FIG. 8 is a side view of the instant food package shown in FIG. 7, and FIG. 9 is shown in FIG. 3 is a plan view in the middle of peeling off a part of the surface material of the hot water lid member to reveal the hot water hole, in which the same reference numerals as in FIGS. 1 to 3 indicate the same members or parts .

  As shown in FIGS. 7 and 8, the separating half-cut 8 of this example is formed by partitioning the surface material 4 into a tongue piece shape, and the peeling tab 9 is formed in the tongue-like partition region. The peeling start half-cut 11 described in the second example is formed on the outer edge of the base. Moreover, the hot water cut hole forming half cut 6 is formed with the width direction of the hot water cut hole 7 (see FIG. 9) defined by the hot water cut hole forming half cut 6 facing the peeling tab 9. That is, the peeling tab 9 is located on the outer edge in the width direction of the hot water cut hole 7 defined by the hot water cut hole forming half cut 6. In addition, although the illustrated tongue-shaped partition region is U-shaped, it may be rectangular, triangular, W-shaped, or the like.

  As shown in FIG. 9, the surface material 4 in this example is peeled off on the tongue-shaped section area defined by the cutting half-cut 8, so it is only necessary to peel off the surface material 4 in a very narrow area. , Peeling work becomes easy. Further, since the tongue-shaped partition region is peeled off while being cut along the cutting half cuts 8 located on both sides of the peeling tab 9, the hot water cut hole forming half cut 6 defines the peeling direction. There is an advantage that it can be surely guided in the width direction of the hot water cutting hole 7.

  The present invention is particularly effective when the base material 3 and the surface material 4 are laminated so as to be peeled with a substantially uniform adhesive force over the entire region. As a laminated structure of such a hot water lid member 1, in addition to the laminated structure described as the conventional example, from the container 2 side, a sealant layer such as polyethylene / a metal layer such as an aluminum foil or an aluminum deposited film / polyethylene, etc. A base material 3 laminated in the order of adhesive resin layer / paper layer, and a surface layer single layer such as polyethylene terephthalate or a surface material 4 laminated with a polyolefin resin layer on the container 2 side, a polyolefin resin layer such as polyethylene or polypropylene. And the like, with the interface between the paper layer and the adhesive resin layer of the substrate 3 as the release surface.
