Referring to Fig. 1, cap envelope 10 of the present invention is preferably with low density polyethylene (LDPE) or polypropylene, but also available high density polyethylene (HDPE) injection moulding is made.Cap envelope 10 comprises taking over a business 9, and its diameter enough covers the top of the neck and the oral area of container (not shown), and the design of cap envelope comes airtight container.Circular first skirt enclose 12 by take over a business 9 peripheral sagging.First skirt encloses the position that 12 length that have depend on the first outer locking edge edge of neck face.As shown in the figure, first skirt encloses first or the upper circular lock-in edge engagement that 12 length enough makes first locking member 15 and container neck surface layer.Sloped sidewall 16 by first skirt enclose 12 tilt sagging.The diameter of the bottom 17 of sidewall 16 is large enough to hold the bottom that cap seals the neck surface layer of the bottle that will be mated.Preferably, sidewall 16 angle of eccentricity between 30 ° and 60 °, preferably about 45 °.
As shown in Figure 3, by first skirt enclose 12 and the intersection of sidewall 16 extend one first locking member 15 inwards.First locking member 15 preferably has the limit 14 that limits groove 20, and groove 20 is located on the radially upwardly extending round flange 19.Round flange 19 and/or groove 20 are preferably continuous, but also can be discontinuous.As shown in Figure 3, limit 14 and groove 20 have " hook-type ", can with the last lock-in edge engagement of the outside of neck, the radius at this edge is identical with groove 20 in fact.Therefore, the shape of groove 20 and radius be advantageously selected to can with the edge engagement of the last blocking device of container neck.Because groove 20 is undercutting, must use core, separablely before from mould, taking out the cap envelope go out or allow to shift out undercutting.For the known various technology of these professional personnel, comprise the core cover of use activity, it can isolate bottom cutting portion from mould.In addition, the undercutting inside of groove 20 can be used as the secondary seal of cap envelope 10, as long as its surface that is shaped forms the space between the outside (not shown) of groove 20 and container neck, reaches the possibility that reduces by limit 14 leak of liquid thereby be used to collect liquid.It is 6 sagging by the bottom 17 of sidewall 16 that second circle skirt encloses, and it comprises second locking member 5.As shown in Figure 1, second locking member 5 has continuous in fact circular inner edge, is fit to second or lock-in edge engagement down with the neck surface layer.Though shown in second locking member be continuous, it also can be made into discontinuous or has one group of bevelled edge slightly.The scheme that replaces is that blocking device is a groove, accepts down lock-in edge with it.But this is not optimal selection, because it can not provide good filling evidence protection.
The bottom 17 of sidewall 16 and second skirt enclose the interface that forms between 6 the top and define first tear line 4.The characteristics of first tear line 4 are that make in the zone of the minimizing material known of those skilled in the art.The zone of this minimizing material has guaranteed that second skirt encloses 6 and is easy to tear off the possibility of sidewall 16, but has prevented from not tear the disengaging that second skirt encloses 6 caps envelope 10.Enclose at first tear line 4 and second skirt between 6 the base 2 and be provided with second tear line 3.
Referring to Fig. 4, at the contiguous place of second tear line 3 and installed outside and torn pulling-on piece 35, it comprises a pair of easily broken element 36 and 37, so that maintenance pulling-on piece 35 and second skirt enclose 6 contact tearing before.When second skirt by cap envelope element body enclosed 6 places and tears pulling-on piece 35, the destroyed and skirt of easily broken element 36 and 37 encloses element to begin to break away from along second tear line 3 and first tear line 4.When first tear line, 4 peripheries are torn fully, second skirt encloses 6 and throws off with cap envelope 10.
Referring to Fig. 1 and Fig. 2, be provided with circular valve 1, it is coiled 9 sagging by the cap envelope.Valve 1 preferably encloses 12 concentric spacing certain distances with first skirt, and this distance equals the distance between neck finish and the outside face in fact.Space between them typically equals the inwardly protruded upper flange of neck.As shown in Figure 1, valve 1 wishes to have at least one preferably a plurality of circular seal edge 54, sagging by its outside face, they compress the inside face of container neck so that form sealing when cap envelope 10 is fastened on the container neck, to improve the sealed engagement between valve 1 and the container neck inwall (not shown) compatible portion.In addition, sagging circle skirt encloses 12 inside face also can be made and have one or more circular seal edge 55, with improve circular skirt enclose 12 and the compatible portion of container neck outer wall between sealed engagement.
Referring to Fig. 1 a, 5,6 and 7, the tip circle dish 9 of cap envelope 10 can randomly be made the shape at center with holes 8, can be moving with the liquid in the Bedpan by the orifice flow of position plug-type pouring nozzle assembly 11 thereon, this assembly can be with high density polyethylene (HDPE) or polypropylene manufacturing, but the most handy low density polyethylene (LDPE) manufacturing.Referring to Fig. 5, hole 8 preferably is formed in the center and and upright cylindrical pouring nozzle main body 7 position alignment of cap envelope dish 9.The upper end of pouring nozzle main body 7 comprises secondary header field 21, and it has hole 22.Cap envelope plunger 23 is located on the secondary header field 21 by one group of upwardly extending support 24 of inclination that distributes along peripheral intervals, separates with hole 22.Referring to Figure 11, this plunger 23 is made up of circular cap envelope dish 41, it have Unitarily molded circle skirt enclose 42 from coil 41 peripheral sagging.Skirt encloses 42 side wall dimensions and should enough approach, so that sidewall can be to internal strain when contact with the centre hole surface 27 of nozzle cap 25, and the while should be enough thick, so that guarantee that plunger 23 can not destroy when repeated usage.Skirt encloses 42 and plunger 23 is connected to tilt supports 24, thereby defines plunger in-to-in cavity 43.
Pouring nozzle assembly 11 also has plug-type cap 25, it is positioned on the upright cylindrical pouring nozzle main body 7 and has the end face 26 of band centre hole 27, it is designed to aim at plunger 23 so that as shown in Figure 6, forms secondary cap envelope when cap 25 rests on the secondary top 21 of upright cylindrical pouring nozzle main body 7 in off position.Inside face at centre hole 27 is provided with at least one, best a pair of circle, be preferably the flange 33 of arc, radially protrude in the centre hole 27.Shown in Fig. 5 a, solid die is made a pair of round flange 33a and 33b on the inside face of centre hole 27.Pair of flanges 33a and 33b are particularly suitable for the sealing of the such liquid of water.But for full-bodied liquid (for example fruit juice), single flange is just enough.The flange 33 that radially protrudes encloses 42 engagements with sagging plunger skirt, so that form the leakproof seal of nozzle 7.Skirt enclose 42 with dish 41 peripheries be connected the configuration flexibility that has increased plunger 23, thereby it is 42 crooked and to internal strain with flange 33 engagements of radially protruding the time to force the plunger skirt to enclose.The form fit that this distortion causes has been promoted secondary cap envelope leak free tight ness rating, compares with other designs with technology now, and this leakproof scheme has great preceence.
Best plug-type cap 25 has sagging cylinder-shaped body element 28, and has the easily broken element 29 of one group of circumferentially-spaced, and the following peripheral of element 29 is filled demonstration with secondary and is with 30 to be connected.Cylinder-shaped body element 28 have that a pair of perpendicular separation distributes in turn over round flange 31, the outside face sliding engaged of they and upright cylindrical pouring nozzle 7.Fill to show and to be with 30 also to have interior round flange 32, the outside face sliding engaged of it and upright cylindrical pouring nozzle 7.Upright cylindrical pouring nozzle 7 has two corresponding outward extending round flange 34a and 34b on its outer surface.Interior round flange 32 is arranged on the opposite of secondary top cover 21 and outward extending flange 34a, this outward extending flange 34a be positioned at cap envelope 10 cap envelope dish 9 above, and with cylindrical hull elements 28 on round flange 31 and secondary fill show be with 30 relative.As shown in Figure 8, secondary fill to show the bridge portion 29a that can have a rise with 30, is extended and/or is extended between them by easily broken element 29.The bridge portion 29a of first rise fills demonstration for secondary and is with 30 to provide support in the cap envelope process of bottleneck, show with 30 excessive vertical deformation and displacements facing to the sagging cylinder-shaped body element 28 of the matrix of plug-type cap envelope 25 to prevent that secondary from filling.Will not destroy easily broken element 29 prematurely if do not do it like this, because the bridge portion 29a that rises plays the effect facing to the hill holder of sagging cylinder-shaped body element 28.In the molding process of cap envelope, fill and show that with 30 identical protective effect also clearly at this moment easily broken element 29 is easy to destruction when extract from mould.Easily broken element 29 is connected to secondary fill shows that the purpose with the bridge portion of 30 rise is to prevent that when container neck assemble the cap envelope from suffering torsion and secondary is filled to show with the 30 axial mismatches with respect to 28 generations of sagging cylinder-shaped body element.
