Anti-through with retainer 182k because big from the overhang of the side 181k of protrusion 123k, fineness degree is also thick, rigidity is than constituting greatly; So with the situation of the locking plate 177k butt that cuts parts 107k under; Locking plate 177k can not cross retainer 182k yet, so that moving of cuts part 107k stopping with perforation 122k consistent location place.On the other hand; The anti-retainer 183k that reverses retainer structure 176k constitutes that overhang is also less, fineness degree is also thin, rigidity is less, the structure of elastic deflection takes place easily; So when the incision action of cutting parts 107k; When the locking plate 177k that cuts parts 107k with anti-when reversing with retainer 183k butt; Though can make retainer 183k elastic deflection, cross and anti-reverse retainer 176k and reach and perforation 122 consistent location; But because this moment, original state was arrived in the anti-retainer structure 176k elastic recovery of reversing, so retainer 176k that should restore and the locking plate 177k butt that cuts parts 107k, inhibition is cut the rollback of parts 107k and is extracted.

Shown in figure 42; If will cut the finger hook clamping part 126k of parts 107k boosts with finger according to sign 131k; Then finger hook clamping part 126k reaches with its cutting blade 124k for one and descends around hinge 110k rotation, and cutting blade 124k cuts flow export 128k opening with seal cover cap 5.If finger hook clamping part 126k is consistent with the height of perforation 122k, then finger hook clamping part 126k is perforated retainer 182k, the 183k constraint at the edge of 122k and keeps posture, the opening end of flow export 128k.If under this state, cup type container is tilted in the mouth, then content liquid flows out from flow export 128k, and the gap 142k between the edge through perforation 122k and the outer rim of finger hook clamping part 126 is outpoured, and can drink.

In this top cover 1k, also have the incision parts that seal cover cap is cut, but this incision parts are except also having the finger hook clamping part that is fixed on the blade spare the blade spare, so the operation of blade spare is easier to, and then the formation of drinking mouth, airport is easier to.Because cutting parts and top cover main body is one, so that the structure of top cover becomes is simple.Because top cover has the outflow guiding walls that erects to the top, so its nozzle member performance function when drinking, drinking of content is easy to.In addition, owing to be fixed on the angle tilt of finger hook clamping part to stipulate that cuts on the parts, so the user infers the direction that the finger hook clamping part is pushed in understanding easily, the incision of seal cover cap operation is easier to.

In addition, because the angle of falling down of finger hook clamping part is below 90 °, so the function of pushing over direction of performance indication finger hook clamping part and the front end of cutting blade can not touch seal cover cap 5, so the front end of cutting blade can not injure seal cover cap 5.

In addition, can visuognosis or touch the sign of identification owing on the finger hook clamping part, be provided with, so can more clearly understand the content of operation.In the case, because the finger hook clamping part self tilts at a certain angle, the side that is provided with the finger hook clamping part of sign can be clear that from the top, so the understanding of content of operation is certain failure-free.

And then the finger hook clamping part covers the cutting blade holding member, the finger hook clamping part only from can see, so can make the process simplification of the action that needs the operator is understood, can not bring uneasiness to the operator.

And; Because locking plate inwardly stretches out the side from the edge of boring a hole, interfere with the finger hook clamping part that has reached perforation, become the position of coplanar so guaranteed finger hook clamping part and perforation; The shape of the flow export of content becomes certain and stable status, so the stream that outpours of content is stablized.

And, be single wall construction owing to flow out guiding walls, so become good, the generation that the liquid in the time of can preventing to outpour in addition accumulates as the mouth contact of drinking mouth.

In addition, be in the outside owing to flow out the interior sidewall surface of guiding walls, so interior sidewall surface is the water guide tubulose, drinking of content is more smooth-going.

Figure 43 to Figure 45 representes top cover 1l, 1m, the 1n of the relevant the 12nd, the 13rd and the 14th embodiment.

In these top covers 1l, 1m, 1n the common barrel-contoured perisporium 115 that is characterised in that covering part 111 spread all over the whole girth around the line of centers 144 be etc. high this point and make from bore a hole 122 lateral margin inwardly the width of the locking plate 141 that stretches out of side become big, with reached bore a hole 122 finger

hook clamping part

126l, 126m, 126n and interfered, prevented that finger

hook clamping part

126l, 126m, 126n from passing function that perforation 122 the enters into cup type container 2 sides reliable this point that becomes.

Can know by above explanation; According to the invention of the 9th to the 14th embodiment, the formation that can access flow export or airport is easier to, constructs also simply, the buyer only just also can infer its method of operation, the top cover of understanding easily through the structure of seeing the incision parts.
