PURPOSE: To enable a consumer to easily recognize that a cover is not separated from a container by a method, wherein when a package is released, the cover is fixed to the container under a broken and separable durable connection.
CONSTITUTION: A container 10 is provided with a cover 20. The cover 20 sealingly closes a film 17, until the cover 20 is removed from a package and protects it. In order to make the package, the lower surface of an annular rim 12 of the container 10 is fixed to a collar 22 of a skirt 21 by a ultrasonic spot welding 37 and at first the skirt 21 is fixed to the container 10. After this operation, a lug 25 of the skirt 21 and a lug 33 of the cover 20 are fixed to each other by a supersonic spot welding 38. With such an arrangement, the plastic material partly melted and moved from one lug to the other lug, a particularly effective coupling is assured between the cover 20 and the skirt 21, resulting in that the package is not accidentally opened. A label is adhered to a paper location of the lug before the package is filled in a box under a state, in which the package is held by the lug at the predetermined location and about 60 pieces can be manufactured in one minute.
