Definitions

• the invention relates to a pressure lid can with an at least one-piece fuselage body and a lid body which, together with a fuselage element arranged at the end of the fuselage body at the closure side, forms a tight closure in which a lever gap between the fuselage body and the lid body remains free for the engagement of a lever which the cover body can be pried open, the cover body having a circumferential, resilient engagement lip which engages from inside with a biasing bead of the fuselage element adapted to the shape of the engagement lip (according to patent application P 40 29 146.4).
• the known pressure lid can advantageously allows the lid body to snap into the locking bead of the fuselage element, so that the lid body is held under prestress in the locking bead plane by pressing the engagement lip with spring force into the locking bead.
• the main advantage of such a closure is that such a pressure lid can be opened without special tools in a non-destructive and simple manner by causing a lever in the lever gap to pull the engagement lip radially inwards while the fuselage element follows is pressed on the outside, whereby the engagement lip in the area of the lever disengages from the sealing bead. By “that the closure engages with a high spring tension, a very good seal can be achieved.
• a further important advantage consists in the resale of closing the pressure lid box, which opened a Mehrfachver ⁇ application, package, optionally in the form of a Mehrwegver ⁇ .
• the invention is based on the object of developing the known pressure lid can with a hinged lid closure in such a way that, while maintaining all the advantages listed, in particular the manufacture of the body of the body is simplified and the filling and sealing of the can is optimized.
• this object is achieved in that, instead of engaging in a separately produced closure bead, the engagement lip of the cover body resiliently engages under an inwardly rolled upper peripheral edge flange of the fuselage element.
• Flare (if it is rolled inwards) can be used directly as a sealing element for the new pressure lid can according to P 40 29 146.4, without having to stamp a separate sealing bead.
• the volume of the can body can be optimally used for filling in such a construction, since the engaging lip of the lid body snaps directly onto the upper peripheral edge of the body.
• the sealing process of the can can also be further optimized, as is shown in more detail below.
• an inwardly embossed fuselage bead is arranged below the peripheral edge flanging at a distance which essentially corresponds to the outside diameter of the engagement lip.
• the diameter of the fuselage body is reduced below the circumferential edge flanging at a distance which essentially corresponds to the outer diameter of the engagement lip so that there is a step offset into the interior of the fuselage body.
• This embodiment has the same effect as the previously described lower fuselage bead and is preferred if the fuselage body is a flatter container, for example in the form of a shell.
• a sealing compound is provided below the peripheral edge flanging in the area in which the engagement lip resiliently engages under it.
• the sealing compound makes the pressure cap can hermetic - -
• the sealant is bactericidal, e.g. by adding ascorbic acid to prevent penetration of the sealant by bacteria.
• the cover body consists of plastic.
• ultra-fine sheet metal would consist of solid material instead of a curl, and the material thickness could be greater.
• means for reducing an overpressure are preferably built into the can, which e.g. can consist of an integrated, semi-permeable pressure relief valve.
• peripheral edge flanging is designed so that it tapers in cross-section by sloping its inner peripheral surface towards its upper end. The aim of this is to make it easier for the lid body to be pressed in when the fuselage body is closed for the first time or repeatedly, since the engagement lip can be pushed outward without great effort by sliding the engagement lip down on the bevel of the peripheral edge flange.
• FIG. 1 shows a partial cross section through the closure area of a first embodiment of the pressure lid can according to the invention in the closed state
• FIG. 2 shows a partial cross section through the closure region of a second exemplary embodiment of the pressure lid can according to the invention in the closed state
• FIG. 3 shows a partial cross section through the closure region of the first exemplary embodiment of the pressure lid can according to the invention during the closure process
• FIG. 4 is a view similar to that of FIG. 3, showing a later stage of the closure process
• FIG. 5 shows a schematic cross-sectional view through a cover body according to the invention with a built-in pressure relief valve in the sealing state
• Fig. 6 is an illustration as in Fig. 5, showing the corresponding pressure relief valve during the escape of expanding gas from the inside of the can.
• the pressure cap can 1 consists of a cylindrical body 2, the upper end of which represents the body element 6.
• the pressure lid can 1 is closed in this part with a lid body 4, the engagement lip 8 of which resiliently engages in the space between the inwardly rolled upper peripheral edge flange 10 of the fuselage element 6 and the inwardly embossed fuselage bead 18.
• the distance between the fuselage corresponds to this - 6 -
• the engagement lip 8 of a cover body 4 ' can also be supported at the bottom on a step 20 which arises from the fact that the diameter of the body body 2 is at a distance which is also essentially corresponds to the outer diameter of the engagement lip, reduced.
• This embodiment is particularly preferred when such a can shape has already been specified, for example in the case of relatively flat shells.
• a sealing compound 22 is provided in both cases between the engagement lip 8 and the space between the peripheral edge flange 10 and the body bead 18 or step 20, the lid body 4 or 4 "and body body 2 preferably being joined together while the sealing compound is still liquid Bactericidal treatment of the sealing compound, for example with ascorbic acid, can effectively prevent the penetration of the seal by bacteria.
• the cover body 4 or 4 'can Regardless of whether a sealing compound 22 is used or not, the cover body 4 or 4 'can, however, be used again in any case in order to close the pressure cover box again.
• This also opens up the possibility of using the inventive pressure lid can (as well as the pressure lid can according to main patent application P 40 29 146.4) several times, possibly in the form of reusable packaging.
• 3 and 4 show the process of the first automated closing of the - 7th
• the cover body 4 is first inserted under prestress into the closure head 30 of a closing device. In this state, the diameter of the cover is reduced to such an extent that the engagement lip 8 is arranged on the entire peripheral edge of the cover body in the position shown in FIG. 3 at a slight distance from the upper end 13 of the peripheral edge flange 10.
• the closure head 30 moves deeper, the engagement lip and the chamfered inner peripheral surface 12 of the peripheral edge flange 10 collide with one another, in which case any excess filler material is squeezed out.
• the medicines ⁇ is edge flange 10 about an axis which lies approximately in the region of the hull bead 18, • pressed over its entire circumference to the outside, first the engagement lip 8 itself and subsequently by the relevant annular extension 32 of the closure head 30 (see Fig. 4). If the engagement lip 8 is located at the level of the space between the peripheral edge flange 10 and the fuselage bead 18, into which the sealing compound 22 has preferably been introduced while still in a liquid state, the closure head 30 moves by actuating the ejector 34, which is located on the upper end 13 the peripheral edge flange 10 supports, again upwards, the cover body 4 now resiliently engages the peripheral edge flange 10 in the manner shown in FIG. 1 and together with the plasticizing sealing compound 22 forms a hermetic seal of the pressure lid box.
• the dome space which is free of product, can be filled with steam by a lance at the moment of pressing in, with a corresponding lid shape.
• the condensation of the steam leads to a negative pressure in the container, which pulls the lid onto the area of the fuselage element 6 covered with sealing compound 22.
• a suitable pressure reduction can be built into the can during the sterilization in order to reduce an overpressure resulting from air or gas.
• Such an integrated, semi-permeable pressure relief valve (a so-called coffee valve) and its mode of operation are shown in FIGS. 5 and 6.
• the membrane 42 of the excess pressure valve 40 lies sealingly on the sealing surface 44 and thereby covers the openings 46 to the interior of the can (FIG. 5). If an overpressure arises in the can (for example during sterilization), the membrane 42 is lifted from the sealing surface 44 in the area of the openings 46, so that the expanding gas can flow out of the interior of the can through the openings 46 and 48 and thus the excess pressure created inside the can is reduced.
