Description

[Detailed explanation of the invention] ``Purpose of the invention'' This invention relates to a wide-mouthed container lid that can accommodate sake, etc.
It is sold sealed and used repeatedly as a replacement lid with a beautiful name plate for drinking or use, and the large area of the wide-mouthed lid is used to achieve an effective advertising effect. To provide a wide-mouth container lid that can be replaced with a replacement lid and is easy to manufacture.

(Industrial application field) A wide-mouth container lid used for cup-shaped containers, etc.

(Prior Art) Cup-shaped containers are widely used for beverages such as sake and seasonings, and have recently been used for furikake foods, dried seaweed, and the like. In other words, the container itself is cup-shaped, which is suitable for drinking, so it is suitable for drinking after opening, and because it has a wide mouth, it cannot be taken out from a container with a narrow opening like seaweed cut into strips. It has the advantage that even such stored items can be easily taken out, and is becoming widely used in various fields.

By the way, such a wide-mouth container lid is made by (a) forming a packing by pouring vinyl chloride foam into the joint of the bottle mouth bead of a molded body made of a thin metal plate such as aluminum, and then forming a packing at the skirt part for breaking and opening. Formed with score lines and pinch pieces, (b)
(c) A bottle made of synthetic resin, in which an outlet is formed in a part of a top plate made of a thin metal plate and a sealing part for the rim of the bottle is formed on the circumferential side, and a sealing piece is glued to the outlet. Using an inner lid that also wraps around the rim of the bottle and an outer lid made of a thin metal plate, score lines and grips are attached to the tightening part for the rim of the bottle, which is formed on the circumferential side of the outer lid, in the same manner as in (a) above. There are some that are formed into pieces.

In addition, as a replacement lid after opening, in the cases of (a) and (b) above, attach a synthetic resin lid to the outside of the thin metal plate lid, remove this synthetic resin lid, and close the seaming part. After breaking or peeling off the seal piece and opening, in case (a), remove the thin metal lid, and in case (b), attach and remove the synthetic resin lid as an inner lid while still attached to the bottle mouth. . In the case of (c), the thin metal plate outer cover is opened and removed, and the synthetic resin inner cover is left behind to be used as a replacement cover.

(Problems to be solved by the invention) In the above (a) and (c), the thin metal plate lid has a trademark or other printing and functions as a nameplate. Since it is removed and discarded when the package is opened, the function as a beautified nameplate cannot be used at all when drinking or using the package after opening, resulting in repeated advertising or recognition effects when drinking or using the package. I can't expect that.

In the case of item (b), the thin metal plate lid remains attached to the mouth of the bottle even after opening, so the advertising or recognition effect as a nameplate printed on the thin metal plate lid remains unchanged even after opening. It can be repeated and gained. However, this effect cannot be obtained unless the synthetic resin replacement lid is removed. Moreover, it requires a process of drilling an outlet in the thin metal plate lid and a special process of separately preparing a sealing piece and gluing and sealing it to the outlet, which increases manufacturing costs and requires covering and sealing the outlet. The seal piece for this purpose requires a knob to peel off and remove it, and it also needs to be wide enough to completely seal the circumference of the outlet, so in some cases it is at least twice as wide as the outlet. As a result, approximately four times as much area will be covered by the seal piece, and the brand effect of the printed decoration will be inhibited in the area covered by the seal piece. In other words, this seal piece covering generally crosses the center of the thin metal plate lid and reaches more than half the area of the top plate, so it is divided into both sides of the top plate, each with a small display area as a nameplate. Therefore, even if there is a large display area for the lid of a wide-mouthed container, the area that can actually be used as a display area is extremely limited, and the display effect is inevitably poor. .

In order to avoid such disadvantages, it is possible to decorate the top plate surface of the synthetic resin lid that is used as a replacement lid, but in this case, the printing beautification is applied to both the thin metal plate lid and the synthetic resin lid. In particular, printing on synthetic resin lids is done using a hot printing method, which means that the price is expensive. Therefore, it cannot be used for products sold in cup-shaped containers of this kind. In other words, there is a limit to the allowable cost for packaging materials such as lids, for example, 10% or less of the product price.
Adopting the duplicative and expensive printing described above within these limits means that the amount of products that can be stored in the wide-mouthed container (because it is wide-mouthed, the amount that can be stored in a container with a narrowed mouth) fraction of a fraction
(or 1/10 or less), it is virtually impossible (the lid member itself is vast, whether made of thin metal sheet material or synthetic resin material, and the printing cost for this vast area is also high). ) That is clear.

Furthermore, the inventors separately stated in (c) above,
The thin metal plate outer lid is separated into a top plate, a lip ring, and a skirt, and an adhesive is formed between the top plate and the inner lid, so that the lid can be opened along the score line. The proposal is to remove only the lip ring and leave the top plate of the outer lid glued to the inner lid. To make it possible to use the complete entire area as a display surface as a nameplate even when used as a replacement lid. However, in this case, a process is required in which the inner lid is separated into a top plate portion and a lip ring portion, and both separated parts are molded separately to function as an integral outer lid. It is necessary to mold each part in this manner, and then attach and adhere them to the inner lid to form the desired container lid, and then mold the separated parts in a manner similar to that of an integral member. It is not always easy to produce a lid with a finished look.

``Structure of the invention'' (Means for solving the problem) It consists of an inner lid made of synthetic resin and an outer lid made of thin metal plate. It has a gripping piece for tearing and opening, and a score line connected to the gripping piece and formed to substantially divide the lip receiving part,
The inner lid is provided with a lip portion that receives the container mouth portion, and an inner cylinder portion formed inside the lip groove and an outer cylinder portion that is connected to and positioned on the inner surface of the skirt portion are integrally formed. A wide-mouth container lid, characterized in that an adhesive portion is formed between the inner lid and the top plate portion of the outer lid.

(Function) The lip groove of the inner lid fits into the bead on the circumferential side of the container opening, and the inner cylinder part hangs down inside and the outer lid hangs down outside.
The outer cover covers the outer surface of such an inner cover, and its skirt portion is wrapped and sealed around the bead.

The lip receiving portion of the outer lid can be divided and opened using the gripping piece and score lines, and even if this lip receiving portion is divided and part or substantially the entirety is removed, the top plate portion of the outer lid or the top plate portion and the remaining lip receiving portion portion maintain an integral relationship because the top plate portion of the outer lid is adhered to the inner lid.

The division of the lip receiving portion by the score line may be performed either on the outside of the lip receiving portion or on the inside thereof.

As mentioned above, the inner lid whose top plate is glued and maintains an integral relationship even after opening can be used as a replacement lid, but when used as a replacement lid, the name plate printed on the ceiling is displayed. It is repeatedly recognized and has a highly recognizable advertising effect.

If the lip receiving portion is divided by the score line on the outside of the lip receiving portion, this lip receiving portion is divided into the lip grooves along with the top plate of the outer lid made of a thin metal plate and the top plate surface of the synthetic resin inner lid. It also covers and reinforces these parts. That is, the durability as a replacement lid is increased, and the thickness of the constituent members can be reduced.

(Example) To explain the specific embodiment of the above-mentioned device according to the present invention as shown in the attached drawings, the device according to the present invention has an inner lid 2 made of synthetic resin and an outer lid 1 made of thin metal plate such as aluminum. The adoption is similar to the conventional method (c) described above.

That is, as shown in FIGS. 1A and 1B, an outer cover 1 made of a thin metal plate such as aluminum is combined with an inner cover 2 made of synthetic resin. 7, a gripping piece 9 for tearing and opening, and a score line 8 are formed, and the inner lid 2 made of synthetic resin has a bead edge 1 of the cup-shaped container 10.
6, an inner cylindrical portion 4 that fits into the inner surface of the bottle mouth, and an outer cylindrical portion 5 that is joined to the inside of the skirt portion 6 of the outer lid 1. In the present invention, the score line 8 on the outer lid 1 is formed to substantially divide the lip receiving part 7, and an adhesive part 18 is formed between the top plate part 12 and the synthetic resin inner lid 2. It was formed.

The division of the lip receiving part 7 of the outer lid 1 along the score line 8 described above can be performed on the outside or inside of the lip receiving part 7, but the division according to the score line on the top surface of the lip receiving part 7,
Making an amputation is not a good thing to do. In other words, the part cut by such a score line is usually sharp, and the fact that the part cut by such a score line remains on the top surface of the lip receiving part 7 is difficult to handle when used as a replacement lid after opening. This is because the cut portion may come into contact with fingertips and cause damage. On the other hand, when the cut portion is formed on the side surface of the lip receiving portion 7, the cut portion is located along the side surface of the synthetic resin lip groove, and the possibility of contact with such fingers is extremely low. . Especially when it is formed on the inside, there is no possibility of it coming into contact with fingers, while the lip receiving part 7
When the gripping piece 9 is formed on the outside of the gripping piece 9, cutting using the score line gripping the gripping piece 9 can be performed in exactly the same manner as in the conventional method. In the case of the inside, the cutting line will be introduced inside beyond the top surface of the lip receiving part 7 to the position shown as 8a in Fig. 3, so the cutting line will be slightly longer, but the cutting will be done in almost the same way. It is possible.

The top plate portion 12 of the above-mentioned outer lid 1 has a nameplate printed 14 such as a trademark or other nameplate.
The skirt portion 6 and the outer cylinder portion 5 are wrapped and sealed around the beaded portion of the cup-shaped container 10 as shown in FIG. Lip receiving part 7 and top plate part 12
It is preferable to form a locking side wall 11 at right angles to the top plate portion 12 and the lip receiving portion 7 between the top plate portion 12 and the lip receiving portion 7. There is an outer cylinder part 5 on the outside of the beaded part 15.
The bending angle is such that the tightening force is not substantially applied to the top plate portion 12 when the seal is tightened and sealed, and is preferably at least 80 degrees or more relative to the lip receiving portion 7. The bending angle is 85° or more and 90° or less. That is, this bending angle
If it is less than 80 degrees, the tightening force will act on the top plate 12 and cause the outer cover 1 and the inner cover 2 to be separated when tightening, and if it is greater than 90 degrees, the outer cover 1 will be bent and the inner cover 2 will be bent.
The removal of the mold after molding becomes extremely complicated, which is disadvantageous in terms of manufacturing and molding, but of course, when trying to obtain a precise integral relationship between the outer lid 1 and the inner lid 2,
A bending angle of 90° or more (90° or less for the top plate portion 12) can be adopted.

For the adhesive part 18 described above, adhesive is used,
Also, it is clear that this can be achieved by partial fusion to the synthetic resin inner lid 2, but as mentioned above, the temperature is 90° or more with respect to the lip horizontal part 7 (90° or less with respect to the top plate part 12). ), especially in cases where the bending angle is adopted, without adhesion or fusion,
Even if it is a simple joint, the top plate part 12 separated by the cut part along the score line 8 will not be affected by the tightening process or come off when used as a replacement lid, and from this point of view, it is practically The purpose of the present invention can be achieved. However, in order to obtain the reinforcing effect of integrating the top plate portion 12 with the inner lid, it is preferable to form the adhesive layer 18. Regarding the above-mentioned outer cylinder part 5, the part according to the present invention is a part that is remolded under the conditions of sealing and tightening with the skirt part 6 in the case of a sake container that is heated by pasteurization after filling with contents. , it fits tightly against the beaded portion and provides an effective sealing effect even when used as a replacement lid.

To explain a specific manufacturing example, the plate thickness is 0.2
A nameplate 14 is printed on the central part of the thin aluminum plate (up to about 0.5 mm can be adopted as appropriate), that is, the part corresponding to the top plate, and a gripping piece 9 is placed on the part located in the middle of the outer surface of the lip receiving part 7. After applying a score line 8 that is continuous with the base of the top plate, a resin primer that acts as a fusion agent is applied to the inner surface of the portion corresponding to the top plate, and then cut to a predetermined size. It was press-molded into a dish shape.

The synthetic resin inner lid 2 was injection molded from a known synthetic resin material to have a cross-sectional structure as shown in FIG.

The synthetic resin inner cover 2 obtained as described above is covered with the outer cover 1 made of thin metal plate, and the top plate portion having the nameplate printing 14 is superimposed on the central recessed part of the inner cover 2, and a heater is applied from above. The resin primer was melted by heating, and both members 1 and 2 were fused together to form a product.

It is clear that the opening of the container of the product obtained as described above can be accurately sealed in accordance with a conventional method using a sealing machine conventionally used for cup-shaped containers of this type. Under the condition that the lip groove of the inner lid encloses the container mouth, the container can be smoothly sealed. As mentioned above, the lip groove portion is reshaped by firing.

To open the container sealed as described above, the gripping piece 9 is raised and pulled along the score line 8 located in the middle of the outer surface of the lip receiving part of the outer lid, which easily breaks the outer lid and divides the lip receiving part 7 at the middle of its outer surface, i.e., the narrowed portion of the lip receiving part 7 that is attached to the bead of the opening can be removed in the form of a thin tape. In other words, the top plate 12 of the outer lid 1 with the nameplate print 14 and the inner surface portion including the top surface of the lip receiving part 7 remain bonded to the synthetic resin inner lid 2, and the inner lid 2 to which such an outer lid 1 is bonded can be used as a replacement lid. In other words, it is clear that the markings printed on the top plate 12 can be repeatedly recognized when used as a replacement lid.

"Effects of the device" As described above, the material costs, printing costs and manufacturing labor required for this device are almost the same as those of the conventional device, and the entire top surface of the outer lid can be used as an effective display area for the nameplate, so that even when virtually the entire lid of this type of wide-mouth container, which has a large area, is used as a replacement lid, it can be fully utilized as a preferred advertising medium, resulting in a repeated recognition effect.Furthermore, since the replacement lid is formed by bonding the metallic nameplate portion to the center of the inner lid 2, the strength of the replacement lid is increased and a replacement lid member with excellent durability is obtained.Furthermore, the outer lid 1 can be handled as a one-piece member and smoothly molded, and glued and sealed, which has the effect of facilitating its manufacture, sealing and other handling, making this a device that is highly effective in terms of practicality and manufacture.
