Description
The present invention relates to easily open at the end, more specifically but be not unique, relate to suchly easily open at the bottom of the metal can, it is used for being connected with a metal can, and a usefulness one plate osed top distribution openings is arranged, a pulling-on piece or ring are fixed at the end, when with the pulling-on piece pull-up, indenture is broken, open this plate with activation and can obtain goods in the jar.
Jar like this is known an end, and for example in GB-A-1540229, wherein, after opening, plate remains adhered on the jar, makes by the pull-up pulling-on piece that pulling-on piece is anterior to be engaged with plate, and opens easily at the bottom of plate is made along the indenture thread breakage jar.
The degree of depth of GB-A1540229 and other known jar end indenture lines is variable, and typically, there are a hard spot or " breakpoint " the jar end of prior art at the indenture line, so that jar can divide two stages to open.This breakpoint reaches by gradually changing of the indenture line degree of depth.F/s allows to tear and ventilate along a dark indenture line, and it has low indenture remnants, and the pressure in making jar equates with external pressure, the indenture line becomes more shallow then, have bigger indenture remnants, opening is not opened at F/s, but must be opened in a subordinate phase.
The jar end with a breakpoint or hard spot, produced many problems in making and using, the goods of variable depth indenture line require to have the instrument of tight tolerances, and life tools have been shortened, in addition, when by along the indenture line than the metal of deep branch-will tear at this place less-when tearing the indenture line and making jar ventilation, according in the jar being malleation or negative pressure, goods may spray, and maybe dirt may be sucked.
When using a pulling-on piece to apply a pressure on the plate of easily opening the end, this pressure makes it open along indenture, and a problem is to control opening of the end satisfactorily.Find that when being a malleation in the jar, when both being a superpressure, just having the end may be suddenly and sometimes the danger that fierce mode bursts open from jar with one.On the contrary, be under a negative pressure and the situation, for example partly or entirely under the vacuum condition, in a moment that is the worse for wear the end of at, just there is the danger that the end may be recessed into or implode suddenly.Under each situation, all may bring problem to the customer, for example, the loss of goods is splashed, even the danger of injury is arranged.
According to FR-B-1590786, under handle, be shaped on one the ventilation indenture, be in handle be fixed in the end rivet near, this system is such design-calculated in theory; When a people made progress draw ring, the ventilation indenture was opened prior to main indenture, allows to ventilate in jar before jar is opened fully.Particularly, for opening of the indenture of realizing ventilating, ring be in main indenture near, this has caused main indenture to be opened prior to the ventilation indenture under a large amount of situations, and total system was lost efficacy.Undoubtedly, one of reason of this design-calculated high failure rate is the resistance of restive ventilation cut channel, and this is because cut channel is the edge shaping at the ring attachment point, and at this place, when rivet was shaped, the metallic character that is subjected to stress was uncertain.
So, the purpose of this invention is to provide a kind of improved jar of end, wherein, even the pressure in the osed top jar is different with external atmosphere pressure, but it opens also Be Controlled, the convenience that stays open simultaneously, this can realize with a for example shape of a hoof ring pulling-on piece.
According to the present invention, provide a kind of and easily opened at the end, comprise a mainboard, it is formed with a distribution openings that is limited by one first indenture line; One closing panel is used for the enclose distributor mouth, and it is connected in mainboard by the first indenture wire-wound, one main portion and by a bendable zone around a remainder; With a pulling-on piece, it is connected in mainboard, and has an extension and that covers closing panel to be used for rear portion with pulling-on piece pull-up from the mainboard.Wherein, comprise a projection on each of closing panel or pulling-on piece or two, be used for engaging with another, and closing panel has second an indenture line relevant with projection, thus, the pull-up pulling-on piece will make the second indenture line break at first.
Best, second or ventilation indenture line below small part is positioned at the pulling-on piece extension, the second indenture line can with first or main indenture line depart from, tear preventing, and guarantee that the ventilation indenture can not expand to main indenture.So, breaking and make in the container and the atmosphere ventilation equates pressure at first taken place under pulling-on piece.So, prevented that goods spill container or suck dirt in the container, because can use constant indenture residual thickness, and avoided low indenture remnants, institute is so that the also increase greatly of the internal pressure of closing panel explosion is higher than the container fracture pressure.
Projection is usually along the common longitudinal of pulling-on piece and plate location, but then also can with axis bias, perhaps, if having more than a projection, they can be located symmetrically with respect to axis.
Pulling-on piece can be connected in the mainboard approximate centre, and opening therefrom mind-set mainboard outer rim extends.So extend at the rear portion therefrom corresponding point in mind-set mainboard edge.Best, pulling-on piece extends through the bendable zone.
Best, the degree of depth of the first indenture line is uniformly, but the degree of depth is also transformable, the convenience of the closing panel that pulls off with improvement.
In general, a first aspect of the present invention preferably beverage is easily opened at the end, and it can comprise a ring handle as pulling-on piece.
According to a second aspect of the invention, provide one easily to open at the end, comprised a mainboard, be used to seal a distribution openings, and passed through one first indenture wire joint in the outside at the end; One is connected in the pulling-on piece of mainboard, and it has an extension, covers a part and a rear portion of mainboard projection at least, is used for handle is lifted away from mainboard and makes extension and protrusion engagement; The first second indenture line relevant with projection, thus, along the initial collapse of the second indenture line generation mainboard.
Best, second or ventilation indenture line partly be positioned under the pulling-on piece.First or the main indenture line even degree of depth normally, this embodiment is preferably especially for food pot.Pulling-on piece for example can be a draw ring.
In another embodiment, can there be two projections to be positioned under the pulling-on piece extension.Each projection has a relevant indenture line, and it can be undulatoryly to tear preventing.
In the present invention on the other hand, provide a kind of and easily opened at the end, comprised that one is used to seal the mainboard of a distribution openings, it passes through one first indenture wire joint in the outside at the end; One is connected in the pulling-on piece of mainboard, and the front end and a rear portion of the second indenture line on the covering mainboard arranged, and is used for pulling-on piece is lifted away from mainboard, and front end is engaged with mainboard near the first indenture line, so that the first indenture line breaks; Wherein, the part that pulling-on piece and/or mainboard to small part is positioned under the pulling-on piece is formed, so that the contiguous first indenture line of front end has one first distance from mainboard, and the part of the contiguous second indenture line of pulling-on piece is nearer from mainboard than front end, thus, take place to break at first along the second indenture line mainboard.
Best, this profile pulling-on piece or mainboard one or both on comprise a projection, this projection can adopt any form.This is furnished with such advantage; Power by the pulling-on piece transmission is applied to the second earlier, or on the ventilation indenture line, or in its vicinity, so, before front end begins to act on the mainboard near the first main indenture line, guarantee that ventilation indenture line opens.So this layout guarantees that before main indenture began to break, the pressure in the container was back to bar pressure.
With reference to the accompanying drawings, mode is described the most preferred embodiment of easily opening the end by way of example.

In Fig. 1, one easily opens at the end, at the bottom of the beverage can, has one by outside 20 mainboards that center on 10 typically.One distribution openings can be operated closing panel 30 sealing by one, closing panel by bendable zone 40 link to each other with mainboard with a main indenture line 50, a pulling-on piece that is illustrated by the broken lines 60 is connected on the mainboard part of an extension 65 covering closing panels 30 of pulling-on piece 60 at 70 places.
One projection 80 is arranged on the closing panel 30, its part is positioned at below the pulling-on piece 60, its relevant ventilation indenture line 90 is all topped by extension 65, the position that is in projection 80 under the pulling-on piece 60 ventilation indenture 90 relevant with it clearly is shown in Fig. 2, in a beverage can, beverage may pressurize, thus pressure be applied to jar at the bottom of on, as shown by arrows.
Fig. 3 has shown that pulling-on piece is in its ventilation position, and the sponson 65 of pulling-on piece 60 rests on the projection 80.Breaking along ventilation indenture 90 in the jar end, allows the vents 95 of gas below extension 65 to discharge from jar.Further lift pulling-on piece, make it be in as shown in Figure 4 open position.Be applied to exceed on the closing panel 30 and make jar the required power of ventilation that main indenture line 50 is broken gradually,, only be connected on the mainboard 10 by bendable zone 40 until closing panel 30 as among the figure shown in 55.So, can from jar, distribute beverage or other goods by the opening that forms.
In Fig. 5 a, the degree of depth of main indenture line 50 is uniform.Actual grade will change according to material therefor, but for generally being about 0.11mm(4.5thou at the bottom of the thick aluminium pot of for example 0.245mm).In at the bottom of the former aluminium pot, remaining indentures (R among Fig. 5 b) are from the 0.11mm(4.5thou of A) be changed to the about 0.15mm(6thou that is used to ventilate at the B place) a breakpoint, to 0.095mm(3.75thon) at the C place, because from the distance of the fulcrum that formed by the extension 65 that acts on closing panel 50, the power that is used at the C place indenture is broken is bigger.The distribution graph of the present invention and prior art diapire residual depth has been shown among Fig. 5 c.
Be surprisingly found out that it is a constant depth that the ventilation indenture line 90 that uses indenture remnants to be less than the separation of main indenture line 50 can make indenture line 50.This has just significantly reduced the instrument cost, and has avoided requiring an indenture line to change the breakpoint of the degree of depth.So, require to allow wideer production tolerance's scope.
Find that also the indenture line 50 of a constant depth can reduce indenture remnants, this has just alleviated the unlatching load.Yet the indenture remnants of main indenture line 50 are greater than the indenture remnants of ventilation indenture line 90, and this point is important, to enable the gas that works along ventilation indenture line 90 advanced persons.
Referring now to Fig. 6 to 8,, wherein shown " standard-sized sheet mouth " end 100 of an easy opening type food cans.In this embodiment, main indenture line 150 cross-over connection jar bottom perimeters.The edge at the end-here be circle-a seam crimping 110 is arranged, be used for the end is fixed to tank body.Tank body is not shown, but it have corresponding shape and size here.Open easily in order to make it not lean on the help of other instruments, the jar end, comprise a main indenture line 150 around bottom perimeter, it is circle and concentric with crimping near crimping 110, also comprise a ring pulling-on piece 160, in this embodiment, obviously do not have the bendable zone as at the bottom of the beverage can among top Fig. 1 to 4, but main indenture 150 can be opened jar fully.
Pulling-on piece 160-is a known common form-have a front end 165, and pulling-on piece is fixed in the mainboard 130 at the end by a rivet.Pulling-on piece in this way is fixed, so that front end 165 can act near the main indenture 150 on the mainboard 130, to carry out the initial unlatching of indenture.Blanked part 171 by mainboard 130 forms a rivet head 170.Blanked part engages and forms a stake with hole 162 on the pulling-on piece.Pulling-on piece 160 also comprises a water chestnut part 161, and it does 90 ° of rotations in a known way around rivet head so that leave mainboard at the draw ring of opening in a moment.Another indenture line 190 or ventilation indenture are formed on the mainboard and are positioned under the pulling-on piece.
The pulling-on piece 160 and/or the mainboard 130 at the end are formed, so that front end 165 is facing to indenture 150, have one to be positioned apart from e from mainboard.Pulling-on piece, and even can contact with mainboard than the more close mainboard of its front end near ventilation another part the indenture 190.As shown in Figure 8, this structure can be realized by the shape of the projection 180 that almost can contact the draw ring medial surface on the mainboard 130.
In the example of Fig. 6 to 8,, there is a single ventilation indenture 190 at a jar end, and it is with respect to pulling-on piece axis of symmetry lateral arrangement (consistent with Fig. 8 cross section).The ventilation indenture had been a preset distance from blanked part 171 both from the pulling-on piece attachment point.By the ventilation indenture being provided one from more remote from cold forging rivet 170 of blanked part-also be, can make the ventilation indenture remain on such position, make its metal indeformable when rivet is shaped.So this position has guaranteed that the characteristic of ventilation indenture when fixing pulling-on piece does not change.
Be formed at projection 180 on the mainboard 130 and be positioned on the plate face and be roughly circle, and a circular contour is arranged.On the other hand, the ventilation indenture is from an arch section, and it approaches raised edges (seeing Fig. 7).Do not interfere with each other with lug boss for draw ring can be fixed, pulling-on piece has the disk of two different depths, and it is concentric with pulling-on piece is fixed in point on the mainboard, both has been concentric with the hole 162 that forms rivet.Projection 180 is positioned at more shallow outer dish 163 times, and rivet is contained in darker inner disc 164 centers.
When draw ring is lifted,, projection 180 at first acted on owing to making ventilation indenture 190.On the other hand,, do not bear any pressure to indenture, so this structure has guaranteed that the ventilation indenture breaks prior to main indenture, so that before main indenture broke, a jar internal pressure was to be in bar pressure because front end leaves mainboard and have one apart from e.
In Fig. 9 to 12, give same numeral with parts identical among Fig. 6 to 8, and no longer be described.In the present embodiment, protrusion-shaped is formed on the ring pulling-on piece 160.As mentioned above, pulling-on piece comprises two concentric discs 163,164 that the two different degree of depth are arranged, and protrusion-shaped is formed on the more shallow outer dish.Projection 181 almost contacts the mainboard 130 at the end near ventilation indenture 190.
In this embodiment, on the outer dish of ring pulling-on piece 160, be formed with two other projections 182.181 one-tenth 120 ℃ of layouts of these two projections and projection can make pulling-on piece be fitted against mainboard better, so, be convenient to rivet and on mainboard, be shaped.
Figure 13 and 14 shows another embodiment of ring pulling-on piece, and wherein pulling-on piece only has a single disk 165, and lug boss is one to be parallel to the bar 166 that the pulling-on piece axis of symmetry extends.Little bar is limited by single disk 165 bottoms usually, and two disk segments 167 are arranged, and it becomes 90 ° sections to extend in bar 165 both sides.When pulling-on piece is fixed in when easily opening on the end mainboard, pulling-on piece pastes onboard by all parts that disk bottom is not depressed, and contacts with wall on the whole radial distance of bar 166 extension between plate and ventilation indenture 190.
In the embodiment of Figure 15 to 17, easily open have on the end mainboard two projections with two on relevant ventilation indenture.Two projections are positioned at ring pulling-on piece axis of symmetry both sides, facing to the outer crimping (seeing Figure 15) of pulling-on piece.As in the previous embodiments, the mainboard of the front end end of from has a distance, when with pulling-on piece when mainboard lifts, two ventilation indentures break prior to main cut channel, when the Rolldown hem of pulling-on piece contacts two projections, the lifting of pulling-on piece applies a downward power on two projections, as embodiment among Fig. 7, each indenture of ventilating has an arch section near its associated tab.
In this embodiment, only there is the single disk of a fixing rivet at the pulling-on piece center.
Figure 18 to 20 comprises an embodiment similar to Figure 15 to 17, and wherein, the present invention is applied to the end of a standard-sized sheet mouth, for example is generally used for sealing at edible jar the end.In this embodiment, as the full open bottom of other embodiment of Fig. 6 to 17, whole mainboard forms closure 130, and indenture line 150 is continuously around by outside 120 closure that center on.So container bottom is opened fully, be the standard-sized sheet mouth that outside, the end 120 is easily opened in a cross-over connection.Food pot is often filled the food with heat, and is closed, so that forms a big vacuum when cooling, and this can cause that the end is to implosive when ventilation.In the embodiment of Fig. 6 to 20, before opening, opens the main indenture of standard-sized sheet mouth one or more ventilation indenture, just overcome this problem.
In Figure 18 to 20, two projections 180 are positioned at below pulling-on piece or draw ring 160 edges from 150 indentations of indenture line.Pulling-on piece is connected in closure 130 by a rivet at 170 places usually.Usually use two projections to come balance to open desired power.Wavy indenture line 190 is positioned partially under the draw ring 160, and departs from indenture 150, is torn or extends to indenture 150 to prevent it.Its position is compared not too important with beverage can, this is because a vacuum arranged in food pot, and it can cause the dust of exterior materials-for example-enter in the jar, and food is gushed out.So its ventilation under pulling-on piece does not resemble the beverage can important, beverage can such as stuffiness, beverage will the splash user.Obviously, the position of ventilation indenture under pulling-on piece is best, yet, can be any dangerous position of malleation (being overvoltage) that in jar, has, this all may exist for beverage can and food cans.
Above being appreciated that only the mode by embodiment the present invention is described, but can change and not break away from the scope of the present invention that the back claim is limited.
