Problems solved by technology

In thick-walled containers, etc., heat conduction takes time, reducing productivity
Therefore, the wall thickness is restricted, and there is a problem that the degree of freedom of the shape of the container and the formed cap is low
In addition, it takes a predetermined time until the heat-sealed part is cooled and completely sealed

Embodiment Construction

[0035] (formed cover)

[0036] The shaped cap according to the present invention will be explained using the drawings.

[0037] refer to figure 1 and figure 2 The forming cover 1 of the present invention is roughly composed of a flange portion 2, an outer side wall portion 3 hanging down from the inner peripheral edge of the flange portion 2, an annular portion 4 extending horizontally inward from the lower end of the outer side wall portion 3, and a ring portion 4 extending from the ring. The inner side wall portion 5 extending upward from the inner peripheral edge of the shape portion 4 and the top plate 6 located horizontally inward from the upper end of the inner side wall portion 5 . A grip portion 8 wider than other portions of the flange portion 2 is formed in a part of the flange portion 2 . The forming cover 1 can be opened by holding the grip portion 8 and pulling the grip portion 8 upward.

[0038] In the above-mentioned basic structure of the forming cap accor...

Abstract

The present invention is a drop-lid-type molded lid that can be fitted to a container having a flange, wherein the molded lid comprises a flange, and first and second tapered sections having fitting sections extending below the flange, guide parts being formed on the lower part of the fitting sections, the inner diameter of each of the guide parts being reduced moving downward, the taper angle [Beta] of the second tapered section being larger than the taper angle [Alpha] of the first tapered section, and the second tapered section being formed in an arc shape that is smaller than the range in which the first tapered section is formed, whereby it is possible to supply a molded lid having exceptional suppliability and fitting properties in relation to the container in the conveyance state.

Description

technical field [0001] The present invention relates to a molded cap capable of fitting to a container having a flange portion and a fitting method for fitting the molded cap to the container. More specifically, the present invention relates to a shaped cap that can be reliably supplied to and fitted to a container even under high-speed conditions, that has good productivity and is capable of sealing. Background technique [0002] A droplid-shaped shaped lid is known as a shaped lid capable of fitting into a cup-shaped container having a flange, and the shaped lid generally includes a side wall hanging downward from the inner edge of the flange and a A top plate formed at the lower end of the side wall. [0003] For the combination of the molded cap and the cup-shaped container, generally, the container conveyed by a conveyor or the like goes through a process including a filling process of the contents, a supply process of the molded cap, a fitting process of the molded ca...
