BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid with a spoon made of synthetic resin that is attached to the periphery of a closed container, and a method for manufacturing the lid.

0002

[Prior Art] Conventionally, a lid with a spoon has been known which includes an annular attachment part attached to the peripheral edge of a closed container and a spoon detachably attached to a part facing the annular attachment part. There is. Further, a fitting groove into which a printed paper for displaying contents is fitted is formed on the inner circumferential surface of the annular mounting portion, and the printed paper is fitted into and held in this fitting groove. On the other hand, a closed container is
For example, it is constructed by wrapping a metal lid around a synthetic resin container body.

0003

[Problems to be Solved by the Invention] As mentioned above, the conventional synthetic resin spoon lid has an annular attachment part, and the printed paper is inserted into the insertion groove formed on the inner peripheral surface of the annular attachment part. It is made up of. By the way, it is time-consuming and labor-intensive to fit the printing paper into the fitting groove on the inner surface of the annular mounting portion one by one. Further, although such a synthetic resin spoon-fitting lid is generally molded by injection molding, it is convenient if it can be molded by press molding, since productivity can be improved. The present invention has been made in consideration of these points, and provides a lid and a lid with a spoon made of synthetic resin that can easily fit the printing paper into the annular attachment part and securely lock the paper, and further improve productivity. The purpose is to provide a manufacturing method thereof.

0004

[Means for Solving the Problems] The present invention provides an annular mounting portion attached to the peripheral edge of a sealed container, an annular stepped portion continuous to the inside of the annular mounting portion, and an annular stepped portion facing each other. a spoon removably attached to a portion where the annular step is attached, and a printing paper is placed on the upper surface of the annular step in a state that it is fitted into the inner peripheral surface of the annular mounting portion, and the upper surface of the annular step is made uneven. A lid with a synthetic resin spoon, which is characterized by being formed into a shape.
and an annular mounting part attached to the peripheral edge of the sealed container, an annular step part continuous to the inside of the annular mounting part and having an uneven top surface, and a removable part attached to mutually opposing parts of the annular step part. The attached spoon is molded by press molding using a synthetic resin material, and then printed paper is placed on the uneven top surface of the annular stepped portion with the printing paper fitted into the inner peripheral surface of the annular mounting portion. This is a method for manufacturing a lid with a synthetic resin spoon, characterized by the following.

[0005]

[Operation] According to the present invention, since the upper surface of the annular step has an uneven shape, by pressing the printed paper against the upper surface, it is possible to easily and reliably prevent the printed paper from coming onto the upper surface of the annular step. This makes it possible to obtain a lid with a synthetic resin spoon that is highly productive.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 and 2 are views showing an embodiment of a lid with a spoon made of synthetic resin according to the present invention. In FIGS. 1 and 2, the lid 1 with a spoon is the peripheral edge 1 of the airtight container 10.
6, and an annular stepped portion 3 continuous to the inside of the annular mounting portion 2. Airtight container 1
0 is made up of, for example, a synthetic resin container body 14 having a flange portion (not shown) at the upper end opening, and a metal lid 11 that wraps around the flange portion of the container body 14. The contents are stored in the container body 14, and the container body 14
The flange portion and the seamed portion of the metal lid 11 form a peripheral edge portion 16 of the airtight container 10. Further, an annular stepped portion 3 is provided inside the annular mounting portion 2 and is slightly lower than the annular mounting portion 2, and spoons 4 are removably attached to mutually opposing portions of the annular stepped portion 3. There is. These annular attachment part 2, annular stepped part 3, and spoon 4 are made of synthetic resin. Further, on the upper surface of the annular stepped portion 3 and the inner peripheral surface of the annular mounting portion 2, a printed paper 5 on which a registered trademark or the like indicating the contents is printed is fitted. Furthermore, the annular step portion 3
The upper surface 7 has an uneven shape to prevent the printing paper 5 from slipping.

Next, a method of manufacturing the synthetic resin spoon-attached lid 1 having such a structure will be explained. First, a method for manufacturing the airtight container 10 will be described. A metal lid 11 is wrapped around the flange portion of a container body 14 in which contents are stored, thereby creating a sealed container 10. The seamed portion between the flange portion and the metal lid 11 becomes the peripheral edge portion 16 of the airtight container 10.

Next, a method for manufacturing a lid with a spoon will be described. First, a synthetic resin material is prepared, and this material is placed in a press molding die (not shown). After that, the annular mounting part 2 and the annular stepped part 3 are formed by pressing the press molding die.
, and spoon 4 are integrally molded. Next, on the upper surface 7 of the annular stepped portion 3 of the spoon lid 1, the annular mounting portion 2
The printing paper 5 is fitted into the inner circumferential surface of. In this case, since the inner peripheral surface of the annular mounting portion 2 has approximately the same dimensions as the outer periphery of the printing paper 5, by pressing the printing paper 5 against the uneven upper surface 7 of the annular stepped portion 3, the printing paper 5 can be held by the inner peripheral surface of the annular mounting portion 2, and the printing paper 5 can be reliably stopped on the uneven upper surface 7. In this way, a lid with a spoon 1 is obtained. Next, the annular attachment part 2 of the spoon-equipped lid 1 is attached to the peripheral edge 16 of the hermetic container 10, and the hermetic container 10 is covered with the spoon-equipped lid 1.

As explained above, according to the present invention, since the upper surface 7 of the annular stepped portion 3 has an uneven shape, the printing paper 5
By pressing against the upper surface 7, the printing paper 5 can be reliably secured to the upper surface 7. Further, since there is no need to provide a fitting groove for printing paper as in the conventional case, a highly productive spoon-equipped lid can be obtained by press molding.

0010

[Effects of the Invention] As explained above, according to the present invention,
By pressing the printed paper against the upper surface of the annular step from above, the printed paper can be reliably locked onto the upper surface of the annular step. In this way, the printing paper can be locked simply by pressing it, so it is easier and simpler than the conventional method of fitting the printing paper into the fitting groove of the annular attachment part. Printed paper can be inserted. Furthermore, press molding allows a lid with a spoon to be obtained with high productivity.
