Definitions

• the invention relates to a pressure lid can with an at least one-part body and a body which, together with the end of the body on the closure side, forms a tight seal.
• Such a pressure lid can is known, for example, from lacquer cans, the indentation lid of which has a radially protruding edge, under which a lever, for example a screwdriver, can be attached, which opens the lid lock with the upper edge of the fuselage body as the lever engagement point.
• a pressure lid can is not suitable for perishable foods that have to be sterilized, since a high internal pressure is generated during sterilization. stands, which this closure cannot withstand.
• a sterilizable folding lid box is known (EP-OS 0 377 588), the lid of which is fastened to the fuselage body with a double fold closure.
• the lid has an annular groove-like depression in its edge area, which serves as a lever gap in order to apply a lever, for example a spoon, and thereby lift the lid.
• the sheet thickness in the bottom of the annular groove-like depression is weakened in the manner of tear-open lids with a scratch
• the disadvantage of this hinged lid box consists in the risk of injury to the sharp tear-open edge remaining on the fuselage body.
• a generic pressure lid can is known in which the lid body has a circumferential, resilient engagement lip which is arranged in a sealing bead of a lip adapted to the engagement lip shape at the end of the fuselage body on the closure side Fuselage element engages under tension from the inside.
• the invention has for its object to provide a generic pressure lid box which on the one hand has a high level of tightness and on the other hand is easy to open, it should be simple and inexpensive to manufacture.
• this object is achieved in that the cover body has a circumferential folded edge which, in the closed state of the pressure cover box, engages around an upper, peripheral edge curl of the fuselage body which is rolled outwards.
• This new principle of a can closure ensures its secure fit and a high sealing effect, which also make it suitable for cans with contents to be sterilized.
• an opening is possible by simply bending the folded edge back into the horizontal, which can be done without irreversible deformation or damage to the lid body, so that the resealability is also ensured.
• the folded edge of the cover body is designed as a border curl rolled downward.
• the fold edge is preferably arranged at the outer end of an annular flange of the cover body which runs essentially horizontally in the unlocked state of the pressure cover can. This is bent when closing the pressure lid can around a substantially central axis by about 90 ° so that the folded edge encompasses the peripheral edge flanging of the fuselage body at its outer end and rests largely on the outside of the fuselage body.
• the annular flange preferably projects from a leg of the same which protrudes upward from the lid body and which bears against the entire surface of the inside of the fuselage body.
• the invention proposes that means are provided in the region of the folded edge, with the aid of which the folded edge can be disengaged from the peripheral edge flanging of the fuselage body without the use of tools when the pressure lid can is closed.
• a particularly simple opening of the can according to the invention (similar to the tear-open lids, but which have the disadvantages mentioned above) is possible, but at the same time it is ensured that a reclosing and reopening is ensured without the leakage ⁇ speed of the closure is impaired.
• the means for opening the pressure lid can is a tab attached to the folded edge of the lid body, with the aid of which the folded edge can be pulled upwards and outwards.
• the tab can be part of a sealing ring clamped between the folded edge of the cover body and the peripheral edge flanging of the fuselage body.
• the invention further proposes that the fuselage body is designed as a resilient leg in the closure area, which can be achieved in particular by the fact that the closure area of the fuselage body attaches to a protrusion of the fuselage body that bulges outward in the form of a loop. In this way it is possible to optimally fit the peripheral edge flanging of the fuselage body into the space between the folded edge and the upwardly projecting leg of the cover body, which makes the closing process simple and without complications.
• Fig. 1 shows a partial cross section through the upper
• Area of an embodiment of the pressure lid can according to the invention in the closed state
• FIG 2 shows the same view as in Figure 1, here the can is shown in the unlocked state, but with the lid body already in place;
• FIG 3 shows an overall view of the pressure lid box according to the invention, showing a possibility for the opening means, the left half of the lid body being omitted.
• a pressure lid can 1 which consists of an essentially cylindrical body body 2, the stability beads 3 has.
• the pressure lid box 1 is closed with a lid body 4, which is supported over its entire circumference with a leg region 11 over the entire area on the upper inner edge of the fuselage body.
• the annular flange 9 projecting from this leg region 11 is bent around a peripheral edge flange 10 at the upper peripheral end of the fuselage body in the illustrated closed state of the pressure lid can 1, so that the edge edging 8 arranged at its outer end engages under it and rests against the outer edge of the fuselage body.
• the closure area of the fuselage body attaches to a protuberance 7 which is bulged outward in the form of a loop, as a result of which it is designed as a resilient leg which, when the pressure cover can according to the invention is closed, easily fits into the space between the edge edging 8 and the leg area 11 of the lid body 4 fits.
• a tab 20 On the inside of the edging 8 of the lid body 4 there is a tab 20 which can form part of a sealing ring 22 between the " lid body and the body of the body " .
• the opening of the pressure lid can according to the invention takes place in a particularly simple manner in that the edge 20 of the lid body 4 of the lid body 4 is bent outwards and upwards with the aid of the tab 20 until the ring flange 9 runs essentially horizontally again, whereby the folded edge of the lid body disengages comes with the peripheral edge flanging of the fuselage body and by further lifting the lid body with the help of the tab 20 an opening of the pressure lid can according to the invention can be achieved.
• FIG 3 finally shows an overall view of a pressure lid can according to the invention in the closed state, the bent edge region of the lid body 4 with the tab 20 attached to it being visible in the right half, while the left side shows it the peripheral edge flanging 10 can be seen in the drawing at the upper edge of the fuselage body 2.
