Detailed description of the invention

Packaging is produced by closing appliance 2, and as shown in Figure 1, described closing appliance 2 is fitted to the open top of container body 4.Closing appliance comprises the base portion 6 being connected to hinged lid 8.Base portion has the skirt section 10 of pendency and smooth horizontal flanges 12, and described skirt section 10 overlays on the neck formation part of container body 4, and described smooth horizontal flanges 12 is seated at the top at the edge of container body and is defined for the opening of access container body matter thing.

Closing appliance is sealed to the edge of container body by induction heat sealed foil 14, the compatible plastic material coating that described induction heat sealed foil has an each surface adhering to paper tinsel the mode described by the patent documentation 0003:EP1656306A in Israel and Palestine encapsulation research Co., Ltd of general section on May 17th, 2006 can be soldered to the edge of container body and the base portion of closing appliance to make described paper tinsel.

Removable portion 16 surrounds opening and is connected to horizontal flanges 12 by frangible region 18.Removable portion is also sealed to induction heat sealed foil 14.The draw ring 20 being lifted to paper tinsel surface is provided to removable portion can be removed by user.

Skirt section 10 is thin-walled and stops with flat edge 22 and at least will leave mark without any inside outshot to make any leverage in described skirt section and be easy to tear skirt section.Each being molded in the corner part 24 in skirt section 10 makes wall cross section reduce in this region.Have further wall cross section reduce rib 26 be molded into these corner parts.Preferably, the outside face of corner part is smooth to make the fragility of corner part not be exposed to user.The region 28 that other wall cross sections reduce can be arranged on the center of the sidewall in skirt section.The region that these wall cross sections reduce is formed paired rib.In order to the formation part 30 engaged with the locking 32 on lid 8 is arranged on the front side wall center in skirt section.

Skirt section 10 is preferably formed make skirt section by plastic deformation relatively low stress and can not return to its original-shape by the polypropylene with low-yield, thus provides the packaging stolen clear evidence opened.Skirt section is relatively dark, and preferred 8mm or the darker impact being still subject to Cost Problems can reach 20mm deeply.But the degree of depth can be restricted to needs by the molded restriction for used concrete plastics can shift out unbroken moulding part from mould, and wherein said plastics must flow into all parts of mould in rational time scale.

Skirt section can have 0.8mm, be preferably less than 0.5mm maximum ga(u)ge and reduce wall cross section can be that 0.2mm is thick, it is thick that described wall cross section is reduced to 0.1mm at rib 26,28 place.Polypropylene be very easily subject to stress cracking impact and when painted material be stretched exceed its yield point time, described material will show permanent white marking.Polypropylene has the yield strength of 12-43MPa and for the application, the material with the yield strength within the scope of 12-20MPa is preferred.The polypropylene being filled with chalk can be used to the skirt section providing relative flimsiness bad.But if draw ring and removable portion want function normal, draw ring and removable portion should be not frangible inadequately.To understand, co-injection molding can be used to be molded to benefit from the most suitable characteristic of the plastics used in the various parts of described parts by the material being different from closing appliance remainder to make skirt section.

If skirt section is pried open by prizing below edge by the sharp instruments of any pattern by attempt, maintenance deflects and will occur variable color by thin wall section.If excessive power is applied to thin wall section, then the easy either side at instrument splits and upwards peels off by described thin wall section.The end of splitting of thin wall section prevents removing and destroy closing appliance and can not re-use to make closing appliance.Carry out if prize attempt at corner part place, then the further fragility produced by reduction cross section rib 26 means that skirt section will be more prone to split and upwards peel off.Ultra-thin rib is as the frangible tie-beam torn being convenient to wall.The area of reduced thickness 28 of entreating in the sidewall may be considered to the most easily open and not show that the part damaged is as target.

All thickness is reduced by the inside face of moulded skirt 10 and provides, if see at Fig. 3.Necessary ridge and rib can be formed in the steel surface of the molded core for generation of closing appliance.The relative size of each several part in skirt section is determined by the density of plastics and melt flow index (MFI) that are used for these parts molded.Because the more low-density plastics with high MFI can flow through the narrow gap between molded core, these plastics will be used to form best details by allowing.The risk that most thin section is damaged when molded core is removed limits the skirt section general thickness of about 0.4mm roughly, although this thickness may utilize the plastics of renewal and molding technique to reduce.Except locking, the outside face in skirt section is perfectly smooth and stops making the main body of the outer wall surface in skirt section 10 and container glossily and the minimum clearance merging continuously and only stay between main body and closing appliance dropping in the thin thin edges adjacent with step 44.The degree of depth of locking only needs about 5mm dark, and therefore the outside face in skirt section can be completely smooth under described height.The outside lines of maintenance packaging are smooth makes more difficult discovery introducing instrument to pry open the inlet point of described closing appliance.

If the horizontal flanges that the groove 34 that wall cross section reduces also is formed in base portion is interior to make to apply lever below skirt section, skirt section can away from the remainder of base portion.This groove 34 is used as linkwork to make any power of levering up being applied to skirt section cause the destruction in skirt section and to make base portion still be in the state being attached to container body edge.

Skirt section is relatively dark, and preferred 8mm or 15mm to 20mm is dark.Because skirt section does not have as sealed package or the structure function supporting content, therefore described skirt section can be formed darker than the closing appliance of routine.Than in as described packaging, skirt section can decline certain point in packaging, and at this some place, recess is provided to allow container body to be grasped.Because lever length increases along with the degree of depth increase in skirt section, skirt section is longer/darker, then more easily guarantee will to rupture at rib or groove 34 place and destroy in skirt section.The degree of depth in skirt section returns the impression of the overall impregnability of user.

Base portion 12 is included in the region 36 in a corner part, and the carrying of described region 36 is designed for and receives and the formation part 38 of holder 40 for storing after removable portion 16 is separated at utensil 40.

The base portion that makes of base portion can describe in the patent documentation 0004:WO99/61337A in the 2 days December in 1999 of aforesaid SPRECKELSENMCGEOUGH Co., Ltd and other prior art patent applications of Bapco Closures Res Ltd. with covering other features be sealed together, and these patent applications merge in this article by reference.

Container 4 has recessed neck formation part 42, and described neck formation part 42 provides the horizontal stand 44 around container body 4, and the lower edge in the skirt section of base portion stops at described place 44 to provide the smooth of packaging and continuous print outside face.The upper limb of neck formation part limits the edge 46 of inwardly upset, and as shown in Figure 4, the edge 46 of described inside upset is sensed is heat sealed to paper tinsel 14.If to make warning message visible for user on the recessed vertical wall that warning message could be stamped or be printed onto neck formation part, user will know that this packaging is not as manufactured and probably stolenly to open.Neck formation part becomes step further backward at second step 48 place.This step preferred angled is so that molded.This provides the exceptional space inside the base portion of closing appliance, and the oral area of described exceptional space and container body is adjacent to receive the formation part 30 inwardly given prominence to from the inside face in skirt section.But this produces another step 48 in neck formation part not can be used in and the depending portion of replacing base portion locking.The recessed vertical portion 50,52 of the neck formation part in use hidden by closing appliance can carry information warning.

Preferably, except any recessed or convex printed text word, neck formation part is smooth vertical wall and not provide around main body any continuously recessed, describedly recessedly continuously can be used to and seal by mechanical device instead of paper tinsel the closing appliance remaining on certain position and engage.

Because container body is sealed by sealed foil 14, container body can be filled until edge 46.Therefore, the degree of depth of closing appliance does not affect for the capacity packed.

The relative size of the thin-walled in skirt section and the degree of depth in skirt section no doubt need to depend on the overall dimension of packaging and are selected.

With reference to skirt section, not there is inside outshot and be intended to refer to the part that the profile that limits from the thick by wall cross section, skirt section inwardly gives prominence to.To understand, but the reduction wall cross section of be easy to plastic deformation in raising skirt section, destroying or peeling off exists does not extend to the whole vertical height part in skirt section, and the wall cross section that lower edge can reduce than these is thicker.But the ridge 60 as occurred at corner part place is not outstanding in the whole profile in skirt section.There is a need to above the edge in skirt section, produce recessed formation part 30 to provide the joint with locking 32.
