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 remains between the fuselage body and the lid body for the engagement of a lever.
  • the lid body can be pried open, and a method for producing a hermetically sealed lid closure for a pressure lid can.
  • Such a pressure lid can is known, for example, from lacquer cans, the push-in lid of which has a radially protruding edge under which a lever, e.g. a screwdriver can be attached, which opens the lid lock in connection with the upper edge of the fuselage body.
  • a lever e.g. a screwdriver
  • Such a pressure lid can is not suitable for perishable foods that have to be sterilized, since a high internal pressure arises during sterilization, which this closure cannot withstand.
  • a sterilizable folding lid box is known (EP-OS 0 377 788), the lid of which is fastened to the fuselage body with a double fold closure.
  • the cover In its edge area, the cover has an annular groove-like depression, which serves as a lever gap around one Use a lever, e.g. a spoon, to open the lid.
  • the sheet thickness in the bottom of the annular groove-like depression in the manner of tear-open covers is weakened with a score, so that the cover opens in the manner of tear-open closures when a lever is attached, without a pull tab having to be attached to the cover.
  • the disadvantage of this sterilizable folding lid box is the risk of injury to the sharp tear-open edge of the closure remaining on the fuselage body.
  • the invention has for its object to provide a Druck ⁇ lid box with openable lid closure, which on the one hand has a high level of tightness and on the other hand is easy to open and the closure of which can be manufactured more easily and cost-effectively.
  • the lid body has a circumferential, resilient engagement lip which engages in a closing bead of the fuselage element from the inside under pretension.
  • the invention advantageously enables a resilient engagement of the cover body in the closure bead of the fuselage element, so that the closure is held under prestress in the closure bead plane by pressing the engagement lip with spring force into the closure bead.
  • the approach of the lever in the lever gap has the effect that, on the one hand, the engagement lip is pulled radially inwards, while the fuselage element is pressed outwards.
  • the engagement lip in the region of the lever disengages from the sealing bead, so that when the lever is pivoted further, the cover can be completely levered out.
  • the cross-sectional shape of the sealing bead is adapted to the shape of the engagement lip, thereby ensuring a secure fit of the closure and a high sealing effect.
  • the engagement lip When the pressure lid can is closed, the engagement lip is first pushed back radially inwards by deforming the circumferential resilient leg of the upper part, in order then to snap into the fuselage bead under prestress.
  • the resilient design of the engagement lip itself also supports the sealing effect in the fuselage.
  • the main advantage of such a closure is that such a pressure lid can can be opened in a simple and non-destructive manner without special tools, particularly with regard to the lid. Because the closure interlocks with high spring tension, an extremely good seal can be achieved. Another major advantage is the resealability of the pressure lid can, which opens up multiple uses. In addition, it is also possible to use the pressure lid can as a reusable packaging.
  • the engagement lip is preferably connected to a resilient leg of the top part of the lid, as seen in cross section, so that when the lever is pressed against the resilient leg, it is possible to push the engagement lip radially inward slightly.
  • the engagement lip is arranged at the outer end of an essentially horizontal annular flange of the cover body.
  • the essentially horizontal ring flange with an engagement lip enables a high sealing force due to the spring force acting radially outwards against the sealing bead.
  • the ring flange can protrude from the resilient leg of the lid upper part and thus transmit the force of the resilient leg to the engagement lip and, at the same time, depending on its inclination relative to the body of the body, determine the direction of the spring force on the closure bead.
  • the sealing bead is preferably embossed to the outside.
  • the engagement lip can snap elastically into such a sealing bead after a radial contraction when the cover body is pressed on.
  • An inwardly embossed lower fuselage bead can be arranged below the closing bead.
  • the lower one Inwardly embossed fuselage allows the cover body to be supported on the side opposite the lever application point when the cover is opened.
  • a second inwardly embossed upper fuselage bead can be arranged above the buckle bead, with which the seal of the buckle can be increased.
  • a sealing means is provided between the fuselage bead and the engagement lip.
  • the sealant makes it possible to hermetically seal the pressure-lid can, the contents of the can being sterilizable when the pressure-lid can is closed.
  • the lid closure according to the invention is particularly advantageous during sterilization because the internal pressure supports the seal to the extent that the internal pressure acts on the resilient leg and thus increases the contact force of the engagement lip against the sealing bead during the sterilization process.
  • This sealing of the lid closure which improves even further with internal pressure, advantageously also enables sterilization without counterpressure.
  • there is a further advantage in cooling due to the contraction of the fuselage since the reduction in the diameter of the fuselage improves the seal when cooling.
  • the fuselage element is integral with the fuselage body.
  • This has the advantage that the V ⁇ . Closing elements on the fuselage can be produced inexpensively simply by producing the beads in the fuselage body.
  • the fuselage element is connected as a separate part to the end of the fuselage body on the lock side by means of a double-fold lock.
  • Such a fuselage element can be prefabricated together with the lid body and then connected to the fuselage body by a filling company in a conventional manner, namely by means of a double rebate closure. This is particularly advantageous for one-piece fuselages.
  • a further advantage of a separate fuselage element is that the lower fuselage bead embossed inwards can protrude further radially inwards, so that the lid is better supported on the lower fuselage bead when opened.
  • the engagement lip is preferably formed by rolling the edge of the cover body. In this way, the engagement lip is manufactured in a simple manner in terms of production technology, with sufficient rigidity of the engagement lip being ensured. The curl can spring again and thus contribute to an improved seal in the fuselage.
  • a force application bead in the cover body which runs lower than the upper edge of the body, enables the defined application of a lever at an optimal force application point of the resilient leg.
  • the force application bead of the cover body preferably runs above the engagement lip in a cover upper part of the cover body.
  • the engagement lip is pulled radially inwards, which makes it easy to open the lid lock.
  • the gap width is reduced in at least part of the circumference and that a lever engagement area is provided compared to the area reduced in the gap width. The reduction in the gap width in at least part of the circumference enables the lid body to be supported on the upper edge of the pressure lid box when the lid body is opened, thereby preventing the lid from being immersed in the contents.
  • the respective pivot axis for the engagement lip is preferably located in the periphery of the upper edge of the lid upper part directly next to the lever gap. In this way, the engagement lip is out of engagement with the closure bead even with a slight lever movement.
  • the fuselage element is arranged in an inwardly tipped upper fuselage section.
  • the reduction in diameter in the upper region of the pressure cap can advantageously achieves stackability of the pressure cap cans without loading the lid body with the weight of the cans lying above it. Another advantage is that the cover diameter is reduced, which leads to a material saving that is not inconsiderable in mass production.

  • the engagement lip 8 engages in a locking bead 10 of the fuselage body 2, which is embossed radially outward in the embodiment of FIG. 1 and is more pronounced in comparison to the stability beads 3.
  • a particularly pronounced lower fuselage bead 18 can be provided below the locking bead 10, which is embossed radially inwards and on which the cover body 4 can be supported when pivoting.
  • an upper radially inwardly embossed fuselage bead 20 can be provided, which can also be deepened by subsequent pressing, that is to say after the cover body 4 has been joined to the fuselage body 2, depending on the pressure resistance required.
  • a sealing means 22 is provided between the engagement lip 8 and the closure bead 10, the cover body 4 and body body 2 preferably being provided with the sealant 22 still liquid be put together.
  • REPLACEMENT LEAF resistance interacts with the opening behavior. There is the possibility of individually determining different subsequent depressions of the body bead 20 for each filling material to be sterilized, in order to obtain an optimum between pressure resistance and opening behavior for each can diameter, each sheet thickness and / or for each filling material.
  • a lever 14 can be attached, which is supported with its free end against the resilient leg 11 of the upper lid part and uses the upper edge 16 of the fuselage body 2 as lever supports.
  • the lever 14 can push the resilient leg 11 radially inwards, while at the same time the fuselage body 2 is pressed slightly outwards. Due to the resilience of the resilient leg 11 of the top cover part, the essentially horizontal ring flange with the engagement lip in the lever engagement region 30 is also pushed back, whereby the cover body 4 initially disengages from the locking bead 10 and then completely with the continued lever movement from the Lock bead jumps out.
  • Another advantage is that the fuselage body 2 contracts when it cools down, causing the
  • REPLACEMENT SHEET Reduction in diameter also has a positive effect on the sealing effect.
  • the lid body 4 of the pressure lid box 1 can be reused to close the pressure lid box again.
  • Fig. 2 shows another embodiment of a lid with a lid body 4 ', the inner region of which is deep-drawn in such a way that the inner surface of the lid surface 7 extends in the plane of the ring flange 9.
  • the lid body 4 ' like the other embodiments of a lid body, can be provided with lid beads 19 in the lid base 7.
  • the upper edge 16 of the fuselage body 2 is rolled outwards, the curl being able to protrude beyond the fuselage diameter or radially inward by tucking in that the upper edge 16 has the same diameter as the fuselage diameter, or a slightly smaller one.

  • the upper edge 16 of the fuselage body 2 is rolled inwards without having a collision with the engagement lip 8 when opening.
  • the lid body 4 1 is designed so that the upper end of the resilient leg 11 when pivoting of the lid body 4 'to the handle portion 30 is supported against the Hebelein ⁇ in the region of the closure bead 10 ver ⁇ running pivot axis of the lid body 4 1 on the curled inwards upper edge 16 and DA prevented by immersing the lid body in the filling 17th
  • the design of the cover according to the exemplary embodiments in FIGS. 2 and 4 results in an increased elasticity of the engagement lip 8 in that, in addition to the swivel axis 32 in the peripheral region of the upper cover part 5, a further swivel axis 33 at the beginning of the deep-drawn region through the Deep drawing of the lid body 4 1 is formed.
  • FIG. 5 shows a plan view of a cover body with an eccentric embossed cover, in which the lever gap 26 has a variable gap width in the circumferential direction of the pressure cover box due to the eccentricity of the upper cover part 5 protruding from the ring flange 9.
  • the reduced gap width enables good support on the top edge of the lid 16 at the point of the smallest gap width, as already shown in principle in FIG. 4, when the lever 14 is applied at the point with the largest gap width.
