Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a lid material for a container used for hermetically packaging instant foods such as raw noodles (hereinafter, simply referred to as instant foods in the present invention), especially for softening and loosening instant foods. The present invention relates to a lid member with a hot water drainage opening provided with a hot water drainage opening for discharging the hot water.

[0002]

2. Description of the Related Art Immediate foods are made by sealing raw noodles, sauces, soups, ingredients, etc., which are hermetically packaged in a cup container (made of expanded polystyrene, styrene, polypropylene, etc.) and hermetically sealed in the container. ing. In eating this instant food, first, the lid material is peeled off from the container opening, and all raw noodles and the like are taken out from the container. Next, the raw noodles are taken out from the pouch, returned to the container, poured with hot water, and the raw noodles are lightly loosened. Next, the hot water in the container is discharged, sauce, soup, ingredients, etc. are added as appropriate, and the hot water is poured again.

By the way, in the conventional case such as instant noodles (cup noodles), a part of the lid material is peeled from the opening of the container, and the soup (sauce) and the pouch containing the ingredients are taken out of the container. However, the dried noodles are kept in the container as they are, the soup (sauce), and the ingredients are added here, then hot water is poured, and the lid is closed again.
The noodles are steamed for a minute, and then the lid material is completely peeled off. For yakisoba, spaghetti, etc., after pouring hot water, the noodles are unraveled, the hot water is discharged, and then the lid material is all peeled off.

The conventional lid material with a hot-water drainage opening, which is mainly composed of this kind of dry noodles, basically adopts a form in which hot water is poured while the noodles are kept in the container. In other words, what was once taken out from the container was soup (sauce), and relatively small volume such as ingredients. In addition, it is desirable that the opening amount of the lid material is as small as possible in order to distort noodles and the like.

In addition, in the lid material for yakisoba and spaghetti, after the partial opening for pouring hot water, it is necessary to open the hot water spout and further to open all the lid material for eating.

[0006]

However, in the instant food targeted by the present invention, it is necessary to take out the noodles having the largest capacity from the container once. For the time being, I tried diverting the conventional container lid material for dry noodles, but I found that the noodles were very difficult to remove unless the lid material was completely peeled off. Moreover, it has been found that there is a drawback in loosening instant food that is very difficult to loosen. It has been found that the reason is that the container lid material for dry noodles basically reduces the opening area of the lid material, so that the opening area of the lid material is necessarily insufficient.

Therefore, the present invention is based on this point of view.
It was developed with the task of obtaining the optimum lid material for the specifications of instant foods. Therefore, a first object of the present invention is to make the opening area of the lid material as large as possible and to enable quick opening. Secondly, it is an object to reduce the number of opening operations of the lid material as much as possible.

[0008]

In order to solve the above technical problems, a lid member with a hot water spout according to claim 1 of the present invention is provided with pull tabs at two different peripheral portions, and a surface sheet and The base material is laminated via an adhesive resin layer, and the adhesive resin layer has a release area coated with a release agent,
The non-peeling area arranged in the peeling area and the other non-peeling area arranged adjacent to the peeling area,
One of the pull tabs on the peeling area side, and the other pull tab on the other non-peeling area side, respectively, a half cut for forming a hot water outlet in the non-peeling area in the peeling area, A half-cut for peeling is formed on the boundary line between the peeling region and another non-peeling region adjacent to the peeling region in a range from the base material, which is on the inner surface side, to the inside of the surface sheet beyond the adhesive resin layer. Further, a portion corresponding to the sealing portion of the container opening of the peeling half-cut is provided with a convex portion projecting to the other pull tab side at a portion immediately before facing the other pull tab on the other non-peeling area side. Further, it is formed substantially in a V shape extending to the peripheral portion.

[0009]

In the lid member with a drainage port having the above structure, first, the other pull tab on the side of the other non-peeling area is pinched and pulled up. As a result, the lid member is peeled off from the opening flange of the container. At this time, the lid material is pulled up so as to be entirely peeled off, which is completely different from the conventional peeling. By the way, the immediately preceding portion corresponding to the sealing portion of the container opening of the peeling half cut has a convex portion protruding to the other pull tab side of the other non-peeling region side, and continues to have a substantially V-shape extending to the peripheral edge portion. Has been formed. Therefore, the force for pulling the other pull tab upward acts almost at the same time as pulling the other pull tab, and concentrates on the tip (point) of the convex portion. As a result, the reason why the topsheet can be separated from the base material is precisely given in this convex portion, and the subsequent separation of the topsheet and the base material can be performed smoothly and lightly. Then, in the other non-peeling area, the lid material is peeled off from the opening flange of the container by pulling up the base material together with the topsheet. Further, on the peeling region side with the peeling half cut interposed, only the topsheet is separated from the base material and peeled off. Subsequently, the lid material is continuously peeled off, and the base material in the portion surrounded by the half-cuts for forming the hot water spout in the non-peeling area in the peeling area is peeled together with the surface sheet in a state of being adhered to the surface sheet. As a result, in the opening of the container, only the base material portion in the peeling region where the hot water spout is formed remains in a state of being bonded to the opening flange of the container. Then, from this state, the instant food, soup (sauce), ingredients, and the like contained in the container are taken out from the opening cut out from the base material. Next, after only the instant food is put in a container and poured with hot water to distort it, the hot water is drained from the hot water removal port of the base material adhered to the container. Next, the other pull tab is picked up and pulled upward, and the base material portion having the hot water spout adhering to the opening portion of the container is peeled off and then removed. Then, put the ingredients or soup in the container and heat it in a microwave or pour hot water to make instant food in a cup.

[0010]

Therefore, the lid member with a hot water spout according to claim 1 of the present invention has the following effects. The other pull tab on the side of the other non-peeling area is pulled upward to peel the lid material from the flange of the opening of the container. As a result, the part surrounded by the half cut for forming the hot water spout is removed together with being bonded to the other non-peeling area. Therefore,
There is an advantage that the hot water spout can be reliably formed, and the opening of the container and the formation of the hot water spout can be easily performed in one operation.

Further, the pulling force of the other pull tab upward acts almost at the same time as pulling up the other pull tab, and concentrates on the tip (point) of this convex portion. Therefore, an opportunity to separate the topsheet from the base material is accurately given in this convex portion, and the subsequent separation of the both can be performed quickly, smoothly and lightly. Moreover, the peeling force applied to the lid member via the other pull tab acts almost at the same time as pulling up the other pull tab, and concentrates on the tip (point) of this convex portion. Therefore, the lid material is swiftly provided with an opportunity to separate the topsheet from the base material, which enables quick opening.

Further, since the lid material is removed entirely by only partially leaving the base material on which the hot water spout is formed, the opening amount can be greatly widened. As a result, there is an advantage that the instant food stored in the pouch from the container can be taken out and the instant food taken out from the pouch can be stored in the container much more easily. At the same time, there is an advantage that it is very easy to loosen the stored instant food.

Further, in the lid member with a drainage opening according to the present invention, as described in claim 2, a half cut is formed on the surface sheet along the base of one pull tab provided on the peeling region side. Is desirable. The strength of one pull tab can be maintained as expected without reducing its thickness. As a result, when peeling the base material portion where the hot water spout is formed, an upward pulling force is firmly applied to the base material portion, and the peeling of the base material portion is significantly facilitated.

Further, according to the lid member with hot water spout according to the present invention, as described in claim 3, at least along the boundary line between the other non-peeling area and the peeling area between the topsheet and the base material. It is desirable that a peeling varnish is coated on both sides of the peeling half cut provided. This is because the separation of the other non-peeling area from the peeling area can be performed reliably and easily.

Further, in the lid member with a hot water spout according to the present invention, the peeling half cut is formed in a straight line shape or is formed so as to be convex toward the peeling region side as described in claim 4. It is desirable to be. In particular, in the case of making it convex on the peeling area side, the opening of the container can be made wider, which makes it very easy to put in and take out the instant food stored in the container and also makes it easy to loosen the instant food. .

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of a lid member with a hot water spout according to the present invention will be described below with reference to the description of FIGS. This lid member 1 with a hot water spout has an outer shape that is substantially the same as the opening 3 of the container 2 in the opening 3 of the container 2 (see FIG.
), Pull tabs 5 and 6 are provided at two different locations on the peripheral portion 4. As shown in FIG. 4, in the lid member 1, a base material 7 and a surface sheet 8 covering the base material 7 are laminated so as to be partly peelable via an adhesive resin layer 9. In particular,
As shown in FIG. 3, between the base material 7 and the surface sheet 8, a peeling area A coated with a release agent 10, a non-peeling area B formed in the peeling area A, and It is partitioned into another non-peeling area C formed adjacent to the peeling area A. Further, as shown in FIG. 4, in the non-peeling area B in the peeling area A, a half-cut 11 for forming a hot water cut is formed over the adhesive resin layer 9 from the base material 7 on the inner surface side. Is formed in a range up to the top sheet 8. One of the pull tabs 5 and 6 has the peeling area A.
Side, and the other pull tab 6 is provided on the other non-peeling area C side, respectively. Further, at the boundary line between the peeling area A and the other non-peeling area C adjacent thereto, a peeling half-cut 12 is formed from the base material 7 on the inner surface side, beyond the adhesive resin layer 9, and the surface sheet 8. Is formed in the range. The lid 1 is subjected to ordinary printing on its surface, and is produced as a lid with a hot water spout having a diameter of 190 mm and a function of discharging hot water by a punching process using an ordinary punching die.

Further, as shown in FIGS. 1 to 3, the portion corresponding to the seal portion 13 of the opening 3 of the container 1 of the peeling half cut 12 is the other pull tab 6 of the other non-peeling area C. In the immediately preceding portion facing each other, a convex portion 14 that projects to the side of the other pull tab 6 is provided, and is formed in a substantially V shape that continues to the peripheral edge portion 4. Intersection 1 with edge 4
2A extends from the convex portion 14 to the peeling area A side in a substantially straight line, and intersects with the peripheral edge portion 4. Therefore, the other pull tab 6
Is pulled up slightly toward the peeling area A side,
First of all, the positional relationship in which the pulling force acts on the convex portion 14 is set first.

Further, as shown in FIG. 5, the lid member 1 is
The instant food container is obtained by sealing the seal portion 15 provided on the flange 2 </ b> A of the opening 3 of the container 2. The seal width of the seal portion 15 is 3 mm to 10 mm.
mm is common.

Here, as shown in FIG. 4, the base material 7 is an EVA having a low temperature adhesive property that facilitates peeling from the container 2 which is molded in advance with a resin such as styrofoam, styrene or polypropylene. A sealant 16 composed of an olefin resin such as (ethylene vinyl acetate copolymer) or a heat-seal varnish is used for 15 to 6
Aluminum foil 17 with a thickness of 0 μm (thickness 7 to 20 μm
It is possible to use the one prepared by laminating or coating the back surface of m) by extrusion.

This sealant agent 16 is, in addition to the above,
For example, the following materials are adopted. For example, E
MAA and ester, polystyrene and polyethylene, polypropylene and polyethylene, and a mixture of polyethylene and polybutene.

In the present invention, the aluminum foil 17 as the metal foil layer is not always necessary. Also,
In providing the metal foil layer, a polyester film deposited with a metal oxide such as silicon oxide or aluminum oxide may be used instead of the aluminum foil.

The topsheet 8 has a thickness of 79.1 g.
It is possible to use the paper 18 within the range of / m ^{2 to} 130 g / m ² , specifically, art paper or coated paper. A printing layer 19 made of ink is provided on the front surface side by the same process as the front and back sides by the gravure printing method. A plastic film is laminated on the print layer 19 of the surface sheet 8 to cover the cover layer 2
4 may be formed. This is for protecting the print layer 19 and the topsheet 8. In addition, examples of the adopted plastic film include PET, OPP, and ON.

On the back side, an edible surfactant such as lecithin, a mixture of digested cotton-based resin with wax or silicon or amide, and a release agent 10 composed of a peeling varnish are similarly gravure. It is formed by printing by a printing method or the like. Further, the release agent 10 is applied.
Before the release agent 10 is applied, it is desirable to apply a sealing varnish on the back surface of the topsheet 8. This is because the peeling performance between the base material 7 and the topsheet 8 is significantly improved.

Further, as the adhesive resin layer 9, an adhesive excellent in thermal adhesiveness to the surface of the printed paper 18 on which the release agent 10 is applied, specifically, HDPE (high density polyethylene). , EMAA (ethylene-methacrylic acid), and LDPE (low density polyethylene). The aluminum foil 17 having a thickness of 10 to 25 μm
A product produced by laminating or coating by extrusion on a (thickness 7 to 20 μm) surface can be used.

The half cut 11 for forming the hot water spout and the half cut 12 for peeling are formed on the inner surface side of the base material 7 over the adhesive resin layer 9 to the surface sheet 8, and approximately 1/4 of the thickness thereof. It is formed in a range up to 3/4.

As shown in FIGS. 1 to 3, the peeling half-cut 12 is formed in a curved shape so as to be convex toward the peeling region A side in a substantially central portion of the lid member 1. .

In the illustrated example, the curved line is formed in this manner, but if necessary, a straight line that crosses the central portion of the lid member 1 may be used as shown by an imaginary line in FIG. To be done. In addition to this, depending on the capacity of the instant food, for example,
1/3 of the lid material 1 or 1 /
A structure provided at four positions is also adopted. In short, it is necessary to strike a balance between obtaining an opening amount that allows instant food to be taken in and out as much as possible and obtaining a remaining amount of the base material 7 that can be safely drained.

A portion of the peeling half cut 12 corresponding to the sealing portion 13 of the opening 3 of the container 1 is formed with a convex portion 14 protruding in a mountain shape on the other pull tab 6 side. . The convex shape is not limited to the chevron shape shown in FIGS. 1 to 3, and an appropriate shape such as a trapezoid or a triangle is adopted. In short, the lid member 1 is attached to the opening 3 of the container 2.
At the time of peeling from the convex portion 14, the upward pulling force first acts intensively at the tip (point) of the convex portion 14, and as a result, the reason why the topsheet 8 can be separated from the substrate 7 is the convex portion 14 It is important that the shape is such that it can be separated smoothly and smoothly after that.

The release agent 10 is printed in the same step on the front and back sides, and the adhesive strength thereof can be appropriately changed depending on the type of each resin used or the dot area ratio. Moreover, as shown in FIG.
In both side portions D of 2, the printing with a solid printing plate is desirable in order to further enhance the releasability between the base material 7 and the surface sheet 8 by the release agent 10. Also, especially in this part,
If necessary, solid printing and halftone dot printing can be used together.

As shown in FIG. 2, the shape of the hot water spout 20 is a circle of 6 to 8 mmφ. However, the shape does not necessarily have to be circular, and various shapes such as an ellipse, a star shape, a triangle, and a quadrangle can be adopted as long as they have the same opening amount.

One of the pull tabs 5, that is, the pull tab 5 provided on the peeling region A side, has a surface sheet along its base, that is, along the peripheral edge of the lid member 1, as shown in FIGS. A half cut 21 is formed from the 8 side. The depth is set from the front side of the topsheet 8 to ⅔ of its thickness to the entire length. The reason why the surface sheet 8 is left on the one pull tab 5 portion together with the base material 7 is to make it easier to grasp the trigger of peeling of the base material portion 7A having the hot water spout 20.

Further, as shown in FIG. 2, the one pull tab 5 is located on the left or right side of the peripheral edge 4 of the lid member 1 with respect to the middle point of the peripheral edge Aa of the peeling area A. It is desirable to be provided at (on the left side in the illustrated example). In particular,
A right or left end of the peeled area A, that is, a portion serving as an opening edge is preferable. The reason is that the pull tab 5 on one side is picked up and the base material portion 7A is attached to the flange 2A of the container 2.
This is because a peeling force can be applied from one end side of the base material portion 7A when peeling from the base material. That is, when the pull tab 5 is present at the midpoint of the peripheral edge Aa of the peeling area A, the peeling force acting on the base material portion 7A from the pull tab 5 is
Evenly distributed on the left and right. As a result, the peeling force becomes weaker, and a larger peeling force is required. Further, by doing so, the one pull tab 5 is present at a position offset from the discharge path of the hot water to be drained. Therefore, even after the hot water is drained, there is no possibility that hot water drops or the like will adhere to the pull tab 5 or the pull tab 5 will be hot, and there is no risk of accidental burns.

In the above structure, the lid member 1 covers the opening 3 of the container 2 with the pull tabs 5 and 6 projecting outward of the container 2 as shown in FIG. 16 layers of the sealant agent and the flange 2A of the container 2 form the seal portion 1.
Heat bonded at 3.

Next, when using the container 2 to which the lid member 1 shown in FIG. 5 is attached, first, the other pull tab 6 is pinched and the lid member 1 is peeled off from the container 2. The lid member 1 is composed of 16 layers of the sealant on the inner surface and the flange 2 of the container 2.
The seal portion 13 with A comes off. Then, this peeling reaches the peeling half cut 12. However, in the region on one pull tab 5 side, that is, in the peeling region A, the base material 7 and the surface seal 8 are laminated via the release agent 10 that is partially coated, and the base material 7 and the surface seal 8 are stacked. Adhesion with 8 is not strong. Therefore, the base material 7 and the surface seal 8 are easily separated at the boundary between the adhesive resin layer 9 of the base material 7 and the release agent 10 layer of the surface sheet 8.

At this time, peeling of the base material 7 and the surface seal 8 is triggered by the convex portion 14. That is, the acting force of pinching the other pull tab 6 and pulling the lid member 1 upward to peel it off from the container 2 acts first on the convex portion 14. This convex part 14
Is convex in the direction opposite to the direction in which the lid 1 is peeled off,
In addition, when the pull tab 6 is placed immediately in front of the other pull tab 6, the upward pulling force is first concentrated on the tip (point) of the convex portion 14, and this portion is peeled prior to other portions. . As a result, the trigger for separating the base material 7 and the topsheet 8 is properly provided in the convex portion 14, and the subsequent separation can be performed smoothly and lightly. Subsequent to the separation of the base material 7 and the surface sheet 8 at the peeling half-cut 12 portion, when the peeling progresses to the hot water gate forming half cut 11, a portion surrounded by the hot water tap forming half cut 11 is formed. Base material 7 is surface seal 8
It is taken out in a state of being adhered to and the hot water spout 20 is formed. Since the back surface of the topsheet 8 with respect to the central portion of the hot water spout 20 is formed in the non-peeling area B where the release agent 10 is not printed (coated) (see FIG. 3). Therefore, the adhesive strength between the surface sheet 8 and the base material 7 in this portion is high, and the portion surrounded by the half-cuts 11 for forming the hot water spout can be easily pulled out to surely form the hot water spout 20.

After the lid member 1 is completely peeled from the container 2 by pinching the other pull tab 6, as shown in FIG. 6, the base material portion on the one pull tab 5 side of the peeling half cut 12 of the lid member 1. 7A, with the hot water spout 20 formed,
It remains adhered to the container 2 and the opening 3 of the container 2 covers approximately 1/2 to 1/2 to 1/4. In this state, take out the contents such as instant food, soup (sauce), and ingredients. Next, the instant food is taken out from the pouch, only the instant food is put in the container 2, and hot water is poured to distort or loosen the instant food for 1 to 2 minutes. Then, the container 2 is tilted to remove the hot water from the hot water tap 20 of the base material portion 7A (the base material 7 in the peeling area A where the hot water tap 20 is formed) adhered to the opening 3 of the container 2. Then
This base material portion 7A adhered to the opening 3 of the container 2 is removed by pinching one pull tab 5 and peeling it off. At this time, if the one pull tab 5 is provided toward the end of the peeling area A, the pulling force for the base material portion 7A can be concentratedly applied to one end of the base material portion 7A. Therefore, the peeling is possible as easily as possible. Then, the soup (sauce) and the ingredients are put in the container 2 and hot water is poured to complete the instant food in a cup such as ramen.

[0037]

Embodiments of the present invention will be described below. (Embodiment 1) This lid member 1 with a hot water spout is manufactured as follows. First, the sealant 16 (25 μm thick) that facilitates separation from the cup container 2 in advance is applied to the aluminum foil 17 (9 μm thick) (the polyethylene adhesive layer 22 may be interposed) to form the base material 7. Create. The sealant 16 is an olefin resin such as EVA having low temperature adhesiveness. At the same time, the roll-shaped paper 18 (coated paper: 84.9 g / m ² ) was subjected to the gravure printing method.
In the same step on the front and back sides, the printing layer 19 made of ink and its front surface side are covered with a polyester (12 μm thick) coating layer 24 by dry lamination through a polyethylene adhesive layer 23, and a silicone resin is used as an edible surfactant on the back surface side. A release agent 10 prepared by mixing the above is applied to produce a topsheet 8. Subsequently, LDPE (low density polyethylene: 15) having excellent adhesiveness to the surface of the surface sheet 8 to which the release agent 10 is applied.
A laminate is obtained by laminating the surface sheet 8 on the surface of the base material 7 using an extruder with the adhesive resin layer 9 having a thickness of (μm). The coating layer 24
May be adopted as needed.

Then, after the laminated wound-up laminated material is largely cut into a sheet shape, a half-cutting process is carried out (there is a case where the half-cutting process is carried out in a winding-up form), and the half-cutting process is completed. After that, the lid material 1 of the present invention is manufactured through a small cutting / punching process (the small cutting / punching process may be performed simultaneously with the half-cutting process).

Then, the lid member 1 is heat-sealed to the cup container 2 so that the sealing width of the sealing portion 13 is 4 mm.
At the same time, the convex portion 14 of the peeling half cut 12 is sealed so that the convex portion 14 overlaps the width of the sealing portion 13 to complete the instant food container having a hot water discharging function. The cup container 2 is formed in advance from, for example, styrofoam, styrene, polypropylene or the like.

In the half-cutting process, the half-cutting bath forming half-cut 11 is a circular linear half-cut, and the peeling half-cut 12 and the half-cut 21 along one pull tab 5 base are both linear. It is formed by half-cutting. In addition, each of these half cuts may be formed by perforation-shaped half cuts, if necessary.

Since the procedure of using the container to which the lid member 1 is attached in this Example 1 is the same as the procedure shown in the first embodiment, its detailed description will be omitted, and the description of the configuration will be omitted. Stay.

(Embodiment 2) Lid material 1 of embodiment 2 of the present invention
Since the basic configuration is the same as that of the lid member 1 of the first embodiment, the same components are designated by the same reference numerals and detailed description thereof will be omitted. The major difference between the second embodiment and the first embodiment is that the shape is a quadrangle.

The laminated material obtained by the same procedure as in Example 1 was cut into a large number of sheets, and then half-cutting was performed (there may be a case where winding is performed).
After the half-cut processing is completed, the lid material 1 of the present invention having a desired quadrangular shape is produced through the small cutting / punching processing (the cutting / punching processing may be performed simultaneously with the half-cut processing).

Then, the lid member 1 is heat-sealed to the cup container 2 so that the sealing width of the sealing portion 13 is 4 mm.
At the same time, the convex portion 14 of the peeling half cut 12 is sealed so that the convex portion 14 overlaps the width of the sealing portion 13 to complete the instant food container having a hot water discharging function. The cup container 2 is formed in advance from, for example, styrofoam, styrene, polypropylene or the like.

In the half-cutting process, the half-cutting bath forming half-cut 11 is a circular linear half-cut, and the peeling half-cut 12 and the half-cut 21 along one pull tab 5 base are both linear. It is formed by half-cutting. In addition, each of these half cuts may be formed by perforation-shaped half cuts, if necessary.

Since the procedure of using the container to which the lid member 1 is attached in this Example 2 is the same as the procedure shown in the second embodiment, its detailed description will be omitted and the description of the configuration will be omitted. Stay.

Two types of lid materials, circular and quadrangular, have been introduced, but the shape may be arbitrarily selected other than these and may be adapted to the shape of the opening of the container.
