Description

  TECHNICAL FIELD The present invention relates to a lid material with a hot water cut hole used for a container for pouring hot water after pouring hot water into noodles and leaving it for a certain period of time like instant foods such as cupped fried noodles and spaghetti.

  Traditionally, instant foods such as cupped fried noodles are stored in containers made of polypropylene, expanded polystyrene, etc., and covered with a plastic molded lid with cuts to form hot water cut holes, and the whole is made of shrink film Shrink-wrapped packaging, or fried soba noodles in a container made of expanded polystyrene, etc., and a cover made of a laminate of paper and plastic film or a laminate of paper and aluminum foil with means for forming a hot water hole Are widely known in the form of a package in which the container is thermally bonded to a container and the whole is shrink-wrapped with a shrink film. As the latter cover material, for example, as shown in the cross-sectional view of FIG. 7A and the cross-sectional view of the method of using the cover in FIG. , 107 projecting from the lower surface of the outer lid 110, the knob 102 and a portion of the lid material 101 with a hot water cutout continuous therewith, the portion facing the tip of the knob 102 and the hot water cutout 109. A partially formed release layer 112 is provided, leaving the non-peeling portion 105 provided on the surface, an adhesive resin layer 130 on the surface of the outer lid 110 where the release layer 112 is formed, and an aluminum foil as an intermediate substrate A layer 122 and a heat-adhesive resin layer 121 are sequentially laminated, and a hot-water cut hole forming cut line 103 that crosses the knob 102 and a hot-water cut hole 104 along a line corresponding to the hot-water cut hole 109 are thermally bonded. Partly formed from the conductive resin layer 121 7B, as shown in FIG. 7 (b), the knob portion 102 of the lid member 101 with a hot water hole that seals the container 140 is raised, and the outer lid 110 is partially separated from the inner lid 120. A configuration is known in which hot water cutting holes 109 can be formed by peeling to perform hot water cutting (see, for example, Patent Document 1).

  However, in the structure of the conventional lid member 101 with a hot water cut hole, as shown in FIGS. 7A and 7B, the hot water cut hole 104 and a partly formed release layer 112 are formed. In the positional relationship with the non-peeling portion 105 that does not provide the non-peeling portion 105, it overlaps with the release layer 112 partially formed as an outer periphery larger than the outer periphery of the non-peeling portion 105 so that the hot water cut hole 104 does not overlap the non-peeling portion 105 Is set to Further, in the manufacturing process of the lid member 101 with the hot water cut hole, it was partially formed to form the position where the hot water cut hole 104 is to be formed and the non-peeling portion 105 at the time of forming the partially formed release layer. Since high accuracy is required for registration with the mold release layer 112, it takes time, and the formation position of the hot water cut hole 104 and the partial formation of the non-peeling portion 105 are performed during the half cut process of forming the hot water cut hole cut. Since it takes time to register with the mold release layer 112 formed in the above, the preparation time of each process becomes long, and the hot water cut hole 104 overlaps with the non-peeling portion 105 due to misregistration, and the hot water cut hole 109 is formed. There has been a problem that defects that cannot be formed well sometimes occur and the yield rate decreases.

  Therefore, the outer periphery of the non-peeling portion 105 is reduced to increase the allowable range of registration between the position where the hot water cut hole 104 is formed and the partially formed release layer 112 that forms the non-peeling portion 105. It was. However, when the allowable range is increased, the knob 102 is caused, and when the outer lid 110 is partially peeled from the inner lid 120 and the hot water cut hole 109 is formed, the portion surrounded by the hot water cut hole 104 is cut off. The hole forming piece 108 must be bonded to the outer lid 110, but the hot water hole forming piece 108 is peeled off from the outer lid 110 and dropped from the hot water hole 109 into the container 140. In some cases, foreign matter is mixed into the contents, which may result in poor quality.

  The first embodiment of the lid member with a hot water hole according to the present invention is as shown in FIG. Fig.1 (a) is the bottom view which permeate | transmitted the principal part of the lid | cover material with a hot water hole of this invention, Comprising: The enlarged view of the non-peeling part 5 is shown in a circle. FIG.1 (b) shows the XX sectional view. The first embodiment of the lid member 1 with a hot water cut hole according to the present invention includes knobs 2 and 7 that project outward at a pair of opposing corners of, for example, a rectangular outer periphery as shown in FIG. The outer lid 10 and the inner lid 20 are partitioned into an easily peelable region P in which a release layer is formed in a substantially triangular region and a non-peelable region N disposed adjacent to the easily peelable region P, In the easy peeling region P, the outer lid 10 and the inner lid 20 are laminated so as to be peelable. As shown in FIG. 1, the inner lid 20 in the easy-peeling region P is formed with a cut hole forming cut line 3 inside the knob portion 2 and closed inside the cut hole forming cut line 3. A shaped hot water cut hole cut 4 is formed. On the inner surface of the outer lid 10, a release layer 12 is formed in the easy-peeling region P, and in the region facing the region surrounded by the hot water cut hole cut 4 of the inner lid 20 in the easy-peeling region P. A non-peeling portion 5 is formed. As shown in the circle of FIG. 1A, the non-peeling portion 5 has, for example, a plurality of corner portions 5a protruding outward, and the hot water cut hole notches 4 at which the sharp ends of the corner portions 5a face each other. It is formed so as to extend from the enclosed area to the outside of the area surrounded by the hot water cut hole cut 4. Further, a strongly bonded portion 5b is formed in which a colored anchor agent is applied in a region where the non-peeling portion 5 is formed. By providing the corner 5 a in the non-peeling portion 5, the area of the non-peeling portion 5 can be widened, and when the outer lid 10 is peeled from the knob portion 2 and a hot water cut hole is formed in the inner lid 20, It is possible to prevent the cut hole forming piece from peeling from the outer lid 10. Moreover, even if the corner portion 5a is formed slightly outside the region surrounded by the hot water cut hole cut 4 by using the corner portion 5a, the corner portion 5a protruding outside the region surrounded by the hot water cut hole cut 4 is formed. Is small, and can easily be formed without hindering the formation of the hot water cut hole 9 (see FIG. 3). Although the strong adhesion part 5b does not necessarily need to be formed, it is more preferable to provide it from the meaning of the present invention. Further, it is preferable to color the anchor agent with a colorant such as a pigment or a dye because the registration work between the release layer 12 on which the non-peeling portion 5 is formed and the strong adhesion portion 5b becomes easy.

  The laminated structure of the lid material 1 with a hot water cut hole of 1st embodiment is as showing in FIG.1 (b). A release layer 12 is formed in the easily peelable region P on the inner surface of the paper layer 11 except for the non-peeled portion 5, and a release layer arranged adjacently via the boundary B of the easily peelable region P is not formed. The outer lid 10 partitioned into the non-peeled region N and the inner lid 20 in which the aluminum foil layer 22 and the heat-adhesive resin layer 21 are laminated form the release layer 12 of the outer lid 10 by the adhesive resin layer 30. The laminated side surface and the aluminum foil layer 22 surface of the inner lid 20 are bonded to each other, and can be peeled between the release layer 12 and the adhesive resin layer 30 of the outer lid 10. The inner lid 20 is formed with a cut hole forming cut line 3 and a plurality of cut hole cut lines 4, and the cut hole forming cut line 3 and the cut hole cut line 4 are formed on the inner lid 20 and the adhesive resin layer 30. It is formed in a state of penetrating through. In addition, the aluminum foil used for the inner lid 20 can be a biaxially stretched polyethylene terephthalate (PET) subjected to light-shielding printing, or a vapor deposited PET on which a metal such as aluminum, silicon oxide, or an inorganic substance such as aluminum oxide is deposited, In this case, a metal detector can be used. As the light-shielding printing, white ink mainly containing titanium oxide or the like, black ink mainly containing carbon black or the like, gray ink mainly containing aluminum paste, or a mixed ink thereof is used.

Further, the hot water cut hole cut 4 having a closed shape according to the present invention is exemplified by a long hole shape in which the width of the hole is narrowed from the knob portion 7 side toward the knob portion 2 side. Any shape can be used as long as it prevents the outflow of water and the redundancy of hot water draining time. Further, the number, size, shape and position of the hot water cut hole 4 for forming the hot water cut hole 9 are arbitrary and may be any one suitable for hot water cutting.
Moreover, although the hot water cut hole notches 4 are arranged radially with the knob portion 2 as the center point, this is a preferred embodiment because it is possible to prevent the noodles from flowing out and shorten the hot water cutting time.

  FIG. 2 is a cross-sectional view showing a state in which the first embodiment of the lid member with a hot water hole according to the present invention is thermally bonded to a container and closed. As shown in FIG. 2, the lid material 1 with a hot water cut hole of the present invention has a surface of the inner lid 20 on a flange portion 41 of a plastic or paper container 40 containing, for example, an instant food having a rectangular opening. An instant food packaging container is formed by covering the opening of the container 40 and heat-sealing the peripheral edge for hermetically sealing.

  Next, a method for forming a hot water hole in a packaging container in which the lid 1 with a hot water hole of the first embodiment is thermally bonded to the opening of the container 40 will be described with reference to FIGS. First, from the state shown in FIG. 2, when the knob part 2 is picked with a finger and the lid material is peeled off, the mold release formed on the inner surface of the paper layer 11 of the outer lid 10 at the portion of the cut hole forming cut line 3. Only the outer lid 10 is peeled off by peeling between the layer 12 and the adhesive resin layer 30. When the peeling further proceeds and reaches the hot water cut hole cut 4 passing through the inner lid 20 and the adhesive resin layer 30, the portion of the inner lid 20 in the region surrounded by the hot water cut hole cut 4 becomes the hot water cut hole forming piece 8. As shown in FIG. 3, the inner lid 20 is formed with a hot water hole 9 formed in the outer lid 10 and is peeled off when reaching the boundary B. A hot water cutting hole 9 is formed in the inner lid 20 which is thermally bonded to the opening. Further, the outer lid 10 is bent toward the knob 7 (in the direction of the arrow in FIG. 3). In addition, it is good also as a structure which provides a cut line in the boundary B of the outer cover 10, and cuts off the part of the outer cover 10 peeled from the inner cover 20. FIG.

  FIG. 4 is a plan view showing another pattern of the non-peeled portion of the lid member with a hot water hole according to the present invention. As shown in FIG. 4, the non-peeling part 5 should just be the structure which has the some corner | angular part protruded outward. (A) is a triangle having three corners 5a, (B) is a rhombus having four corners 5a, (C) is a shuriken shape having four corners 5a, (D) is a circle and 5 A shape in which the corner portions 5a are combined, (e) is a star shape having six corner portions 5a, and (f) is a shape in which an ellipse shape and eight corner portions 5a are combined. The curve circumscribing the non-peeling portion 5 indicates the hot water cut hole cut 4. The shape of the non-peeling portion 5 is not limited as long as it has a corner portion without departing from the spirit of the present invention. In FIG. 4, the hot water cut hole cut 4 is exemplified by circumscribing the non-peeling portion 5, but the corner portion is in a region surrounded by the hot water cut hole cut or in a region surrounded by the hot cut hole cut. Needless to say, it may be formed slightly outside.

  In addition, as an anchor agent for forming the strong adhesion portion 5b, an anchor coating agent such as isocyanate, polyethyleneimine, organic titanate, or butadiene can be used, and the release layer 12 is obtained by gravure printing or flexographic printing. If it is formed in an in-line process, a high registration accuracy can be obtained, which is a preferable method.

  Examples of the adhesive resin layer 30 for bonding the outer lid 10 and the inner lid 20 include heat such as polyethylene, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / methacrylic acid copolymer, ionomer, and polypropylene. A plastic resin can be used, these are hot-melt extruded, and the outer lid 10 and the inner lid 20 are laminated by extrusion lamination. In addition to this, an emulsion resin or dry laminating adhesive can be used to form the adhesive resin layer 30 by roll coating, gravure coating, kiss coating or the like, and lamination can be performed by wet lamination or dry lamination, but an extrusion lamination method with high productivity is preferable. .

  The heat-adhesive resin layer 21 on which the innermost layer of the inner lid 20 is laminated is mainly composed of an ethylene / acrylic acid copolymer or an ethylene-methacrylic acid copolymer that can be melted by heat and extruded. Resins can be preferably used. The thermoadhesive resin layer 21 may be laminated directly on the aluminum foil surface by extrusion lamination, or may be laminated via an extruded polyethylene layer. The heat-adhesive resin layer 21 may be made of polyethylene, an ethylene / vinyl acetate copolymer, or a resin obtained by mixing polystyrene, polybutene, or the like with the above resin. These resins are easily peelable from the container 40 and are appropriately selected depending on the material of the container.

Specific examples of the structure of the outer lid include biaxially stretched polyethylene terephthalate 12 μm / urethane adhesive / printing layer / paper 60 / m ² / partially formed release layer, biaxially stretched polyethylene terephthalate 12 μm / polyethylene 20 μm / Print layer / paper 60 / m ² / partially formed release layer, print layer / paper 80 / m ² / partially formed release layer, and the like.
Specific examples of the structure of the inner lid include polyethylene 20 μm / aluminum foil 7 to 15 μm / thermal adhesive resin 25 μm, polyethylene 20 μm / aluminum foil 7 to 15 μm / polyethylene 20 μm / thermoadhesive resin 20 μm, and the like. The underlined polyethylene indicates a layer corresponding to the adhesive resin layer 30. In the present invention, the outer lid and the inner lid are peeled between the release layer and the adhesive resin layer. It should be included in the lid layer.

  In 1st embodiment, although the shape of the cover material 1 with a hot water cut hole was demonstrated as a square shape, a shape is arbitrary and may be circular shape, elliptical shape, etc. The cut line 3 for forming the hot water cut hole and the cut line 4 for the hot water cut hole are the inner lid 10 in which the release layer 12 is formed on the paper layer 11, the aluminum foil layer 22, and the thermoadhesive resin layer 21. After the lid 20 is laminated through the adhesive resin layer 30 to produce a laminate for the lid material, the lid 20 is formed by half-cutting from the surface of the thermal adhesive resin layer 21 of the inner lid 20. .
