Definitions

  • the invention relates to a preserve, especially for jams, fruit or vegetables, which is in the closed state under negative pressure, with a preferably formed of glass container and a screw cap, which is provided with an opening, the first time a pressure equalization between the interior of the preserve and the surrounding outer space of the preserve causes, wherein the opening is provided with a resealable, sealed closure means.
  • the utility model G 92 00 763.5 discloses to provide the screw cap with a hole-shaped opening which is covered with a tearable or pierceable foil. To open the packaging, the cover film is first torn off or pierced, so that a pressure equalization takes place and the packaging is easy to open.
  • said utility model deals with the formation of the opening in the screw cap.
  • the cut edges of the hole-shaped opening are bent outward so that they are directly facing the externally applied sealing film, and thus reliably covered in the application of the sealing film of this.
  • the closure means (screw or valve) must be lowered in the screw cap.
  • Opening containers that store food will shorten the shelf life. Similarly, opening the closure means has this effect.
  • a disadvantage of a resealable closure means lies in the lack of controllability of the first use.
  • the opening mechanism could be erroneously operated by mishandling during transport or sorting on the shelves of grocery stores, causing premature spoilage of the food. It is also conceivable that end consumers use the opening when shopping to smell the product. The possibility of malicious poisoning or manipulation of such canned food is given.
  • This object is achieved in that at least one feature of a seal is irreversibly changed when opening the closure means.
  • the seal is irreparably changed, so that this is the hallmark of a manipulated product. Of the Customer has the opportunity to immediately exchange the goods for a sealed product.
  • the closure means embodied, for example, as an adhesive strip preferably consists of a region permanently adhering to the screw cap and a region which can be removed therefrom.
  • the seal forms a unit with the closure means before opening, which when applied to the container has the advantage that it can be applied in one process step.
  • One possible embodiment of the seal is a perforation.
  • the perforation separates the two areas from each other, so that when lifting the removable part of the permanently adhesive area extends, for example, U-shaped around the opening.
  • the first use of the closure means ruptures the perforation and forms the mark for the already 'used' preserve.
  • seal and closure means form separate units. For example, this is done by placing a tab across the two areas (permanently attached and removably attached). The ends of the tab may be attached directly to the closure means or on the screw cap. By lifting the removable area the easily breakable tab is severed and forms the hallmark of the product used.
  • the identification by discoloration of the removable area may be coated with a substance which reacts with the oxygen in the air and thus causes discoloration. It is conceivable as well as the arrangement of a dye-filled strip, which expires when damaged and spreads the color.
  • a film resistant to temperatures of up to at least 98 degrees Celsius such as metallised plastic film, metal foil or a composite material made of plastic and / or or metal foil and / or paper.
  • the closure In addition to heat resistance, the closure must withstand a certain vacuum. Immediately after filling the food into the containers, the pressure difference between the container interior and the container environment is about 250 mbar. After the food has cooled, the pressure difference increases to about 400 mbar.
  • closure means must be made of a material that ensures airtightness or a gas impermeability between the container interior and container environment. Otherwise, there is a risk that the taste or smell of food stored next to it will falsify the original taste of the preserved food or vice versa.
  • the closure means thus creates a barrier between the interior and the environment.
  • the adhesive with which the adhesion of the closure means to the screw cap, retains its adhesive properties even with repeated use retains its adhesive properties even with repeated use.
  • a conserve 0 is shown as an example in section, which is filled with jam, fruit or vegetables 9. It consists of a container 1 made of glass, which is closed with a screw 2. This screw cap 2 is provided with an opening 3, which in turn is closed by a closure means 4.
  • the closure means 4 consists of a silver aluminum foil having a thickness of 40 microns and a basis weight of 105 g / m 2 .
  • the aluminum foil is applied with an adhesive 5 of permanently adhering acrylate adhesive.
  • an ear 8 which is advantageously made thicker and to which no adhesive is applied. Two finger gripping is greatly facilitated.
  • Figure 2 shows a first embodiment of the closure means 4 in plan view.
  • An adhesive region 10 is separated from the releasable region 11 by a perforation extending on both sides of the detachable region 11.
  • the end of the perforation at the rear of the closure means provides greater resistance to peeling, thereby causing a user to terminate the peeling operation.
  • the detachable region 11 of the film is still part of the closure means 4 and can be glued again after pressure equalization in the preserve 0.
  • a tab over the releasable portion 11 and the adhesive portion 10 is arranged.
  • the ends of the tab are attached directly to the closure means 4.
  • the tab is severed by lifting off the releasable portion 11.
  • the user is also caused to finish the peeling operation when the resistance to peeling in the rear portion of the sealing means becomes larger.
  • This is provided by two, similar to the perforation, introduced in advance cuts in the film, which are arranged between the releasable portion 11 and the adhesive portion 10. In the area of the incisions, the lifting of the film is smooth, whereas the end of the incision represents a resistance.
