The specific embodiment
With reference to figure 1 and Fig. 2, plastics closure 10 is depicted as has circumferential collar 11, is used for around the dispense aperture of container, being attached to the fluid container (not shown).For example, attachedly can pass through screw thread 12 (see figure 3)s, bayonet fitting (not shown) or other known attachments.
A plurality of leaf 13 are positioned at the top of the collar 11, and are attached on the collar 11 by integral hinge 14 (seeing Fig. 5 especially).Though show eight this leaf 13, quantity obviously can change.In the make position of closure member 10, leaf 13 is in the horizontal surface of substantially flat, to extend adjacent to each other shown in 3,4 and 5 at Fig. 1.Each leaf 13 has similar leg-of-mutton shape, and it has two long sides 15 on the direction away from the hinge 14 relevant with specific leaf 13, assembling.The long side 15 of each leaf 13 is adjacent at the long side of the make position of closure member 10 and adjacent leaf 13.
A plurality of thin, soft, integrally be attached on the leaf 13 for folding 16, and between leaf 13, extend, each is extending sheet 16 between the long side 15 of two adjacent leaf 13 and is being attached on the long side 15 of two adjacent leaf 13.Sheet 16 can have the thickness of 0.005 inch order of magnitude, and leaf 13 can have the thickness of 0.040 inch order of magnitude, and it is as just example.In the make position of closure member 10, each sheet 16 be folded in adjacent double-type leaf 13 below, and long leaf side 15 is adjacent one another are.When closure member was opened, long leaf side 15 was with each interval.
For example, closure member 10 will be attached on the squeezable fluid container usually.When the manual compression container, the pressure of fluid to be allocated force leaf 13 from Fig. 1 position of their substantially flat to Fig. 2 position, in Fig. 2 position each leaf around its hinge 14 upwards pivot and with it adjacent leaf at interval.Sheet 16 launches between leaf 13 now and stretches.Therefore, on closure member 10, form dispense aperture 17, to allow the distribution of fluid product.Less Manual pressure on the container will produce less opening 17, and bigger Manual pressure will produce bigger opening.This opening of closure member 10 is shown in Fig. 2, in 6 and 7, for clearly explanation, except a sheet 16, all sheets 16 is not shown in Fig. 6.
When required product volume distributes through closure member 10 and discharges squeeze pressure; Leaf 13 will pivot downwards around their hinge 14 and occupy the make position of closure member in Fig. 1 once more, wherein sheet 16 once more between adjacent leaf 13 with below fold up.At squeeze receptacle no longer, get back to this downward pivot that suction in the container helps leaf 13 with product after the allocated product.
