が知られている(実開昭61−12726号公報)。(Prior Art) Conventionally, waterproof containers made of paper, plastic, glass, etc., filled with liquid beverages such as juice, have been widely produced and sold. As a lid for sealing the opening of such a container, a lid material is known in which a coating layer is adhered to one surface of a base material layer having a fluid outlet using an adhesive that is easily peeled off (in practical use). Publication No. 12726 (Sho 61-12726).

である。(Problems to be solved by the invention) (a) The lid is usually printed with characters explaining the contents, how to open it, the name of the manufacturer, etc., and other designs as necessary. In the lid material described in the above publication, it is preferable to use a film or sheet made of plastic with excellent mechanical strength and other physical properties as the base layer, and an aluminum foil with excellent gas barrier properties as the covering layer. It is said that it is advisable to further cover the upper surface of this coating layer with a protective layer made of plastic, if necessary. The above characters and designs are printed on the surface of the protective layer made of plastic.
In order to industrially advantageously produce such lids, a wide and long plastic film is used as the protective layer, on which letters etc. are printed in pitch in correspondence with the positions to be punched into each lid. The base material layer is a wide and long plastic film with holes that serve as fluid outflow ports punched into each lid at corresponding locations on the lid. A long length of aluminum foil is laminated and bonded in a predetermined order so that the printing on the protective layer and the fluid outlet on the base material layer are in the appropriate positions, and each laminated seal is made from the resulting laminated seal. Punch out the lid. However, it is extremely difficult to ensure that the fluid outlet of the base layer and the printed portion of the cover layer overlap in the proper position and maintain their relative position during long continuous operations. .

るおそれがある。(b) In the lidding material described in the above publication, the surface facing inside the container to be lidded is a base material layer made of plastic film or sheet as described above, and the top surface thereof is a coating layer made of aluminum foil. However, they are laminated and bonded using an adhesive that is relatively easy to peel off. Therefore, the inside of the container and the upper part of the lid are blocked by an aluminum foil with a high gas barrier property, but the fluid outlet provided in the base layer is separated by a peelable layer where the base layer and the coating layer are bonded. It comes into contact with the outside air through a layer of adhesive, and there is a risk that gas may flow through this route.

によつて達成された。(Means for Solving the Problems) The purpose of the present invention is to provide a lid material that solves the above-mentioned problems. The lower surface (i.e., the surface facing the inner surface of the container when the container is covered) is layered with aluminum foil that has a high gas barrier property to block out gas. By printing on the material layer itself, it is easy to align the fluid outlet and the applied printing, and the upper surface of the printed base layer is covered with a transparent coating layer, and the printing is applied to the base material layer. Printing was achieved by making it clearly visible from the outside.

This layer is made of a strong adhesive. Note that the adhesive strength must not be so weak that the coating layer 6 will peel off even if it is slightly rubbed during handling of the container product with the lid attached. Such adhesives are commercially available and can be selected from among them. Specifically, there are acrylic, polyester, and polyurethane adhesives. In order to make the adhesive relatively easy to peel off, an appropriate amount of a release agent such as silicone can be added to the adhesive component to reduce the adhesive strength to a desired degree.

仕上げる。 To illustrate the method of manufacturing the lid material of the present invention shown in FIG. 2, first, wide and long constituent layers are prepared. The base material layer 1 is pre-drilled with a large number of holes to serve as fluid outlet ports 8 at predetermined positions in the length direction and the width direction. Further, on the base material layer 1, explanations of the contents of the container, how to open the container, characters of the manufacturer's name, etc. are printed in advance. Further, as the adhesives indicated by numerals 4 and 7 in FIG. 2, film-like polyethylene heat-sensitive adhesives were used, and these were also prepared as wide and long belts with the same dimensions as the base material layer. do. Then, these are stacked as a whole or divided and stacked in the order shown in Fig. 2, and passed through a pressure roll.
Laminate by pressing under heat. To give an example of dividing, grouping, and laminating, a base material layer 1 and an easily peelable adhesive layer 5 are laminated, a covering layer 6 and an adhesive layer 7 are laminated, and the layer is pressed. The laminate is laminated by passing it through a roll, and then a laminate of a sealing layer 3, an aluminum foil layer 2, and an adhesive 4 is superimposed on this laminate, and being laminated by passing it through a pressure roll,
Finish.

刷を施してもよい。 As described above, explanatory text about the contents of the container and the like are directly printed on the base material layer 1. Since the fluid outlet 8 is perforated in the base material layer 1, the alignment of the fluid outlet 8 and the printed area such as letters is easily and accurately performed, and during the subsequent process until the completion of the lid material, There is no possibility of misalignment. Since the covering layer 6 is transparent, the printed content can be clearly seen from the outside.
Printing of characters, etc. on the base layer 1 can normally be done on the top surface of the base layer 1 (the side facing the outside of the lid), but if the base layer 1 is transparent, printing on the bottom surface thereof is sufficient. may be applied.

The knob piece 9 is provided with a notch 10 at its base that reaches the easily peelable adhesive layer 5, and by pulling the knob piece 9, the coating layer 6 is removed.
and the layer of adhesive 7 is peeled off. When this peeling reaches the location where the fluid outlet 8 is provided, the hole of the fluid outlet 8 is filled with adhesive, so this adhesive is absorbed into the aluminum foil layer below it. 2 and the sealing layer 3 upward;
Tear this part apart and lift it up. That is, the state is as shown in FIG. In FIG. 3, reference numeral 13 indicates the adhesive in the hole portion of the fluid outlet 8, and the aluminum foil layer 2 and sealing layer 3 that have been adhered thereto and torn.

は全く起らない。(Effects of the invention) (a) A base material layer made of polyethylene terephthalate with excellent mechanical strength is used, a fluid outlet is provided in advance, and an aluminum foil with excellent gas barrier properties is used on this base material layer. With conventional lid materials, which are laminated using an adhesive that is easy to peel off, when adding printing such as a description of the contents of the container,
A plastic film with such printing is laminated onto the aluminum foil. When the printed plastic film layer and the base material layer having the fluid outlet are separate from each other in this way, when the whole is laminated, the position of the printed part and the fluid outlet must be in an appropriate relationship. However, when laminating work is carried out in an efficient continuous operation, misalignment is likely to occur between the two. In the lidding material of the present invention, the fluid outlet is perforated in the base material layer and the printing is applied to this layer, so that no misalignment occurs during continuous production operations.

活用される。(b) With the lid material of the present invention, when a container is covered with this lid material, the layer of aluminum foil, which has excellent gas barrier properties, is located below the base material layer, that is, at the position closest to the container. Therefore, gas barrier properties are utilized.
