Definitions

  • This invention concerns the appliances to create a vacuum in containers for the preservation of vacuum-packed products, containers which can be flexible such as bags or rigid such as vessels or canisters, and to seal the containers when they are flexible.
  • apparatus that basically comprise: a body; a cover or lever movable as regards to the body between an open and closed position; a suction chamber between the body and the cover to receive the mouth of a bag; a suction pressure device pneumatically connected to said chamber to suck the air out of the bag to create a vacuum when the cover or lever is in the closed position; and a heat sealing bar to seal the mouth of the bag to preserve the vacuum condition.
  • the body of such appliances also acts as a base and encloses the suction pressure device
  • the cover or lever is hinged to the body, moving above the latter, and can be equipped with means to block it when closed and has a front area with control means and display of the vacuum, a discharge valve and possibly a connection in communication with the suction pressure device to connect a suction tube to it to create a vacuum in rigid containers equipped with an appropriate cover.
  • An appliance to create a vacuum in containers and seal them for the preservation of vacuum- packed foodstuffs was also proposed, which is made up basically of a base plate or tray forming at least a part of a suction chamber, and of a body, that forms a remaining part of said chamber and that encloses a suction group and comprises a heat sealing bar and command means of the functions of the appliance.
  • Such body is associated with the base plate or tray and movable above the latter between an open and a closed position of the suction chamber and the upper body is also removable from the plate or tray to allow the latter, that is the plate or tray, to be washed without involving the body enclosing the suction pressure device and on the whole the electric components.
  • the object of this invention is to provide an appliance for creating a vacuum of the type with a plate or tray base separable from the above upper body that holds a suction unit, a heat- sealing bar and the device's function commands, but without a basin and equipped with means to simplify its construction and ensure its functionality and reliability.
  • the base plate or tray no longer has a basin in line or coincident with the suction chamber but, if present, the basin is moved parallel away from said chamber, to the rear of the plate or tray, and as regards to said chamber there are other functional means for the positioning and preventing the loss of liquid from the mouth of the bag during the suction phase.
  • the apparatus for creating a vacuum proposed herein comprises a base plate or tray 21 and an upper body 22.
  • the plate or tray 21 is provided with a pair of lugs 23 each having a saddle type seat 24 accessible from the top to bottom by means of an opening 25.
  • the upper body 22 has two pins from two opposite sides, - not shown- designed to connect through the openings 25, with the saddle type seats 24 of the lugs of the base plate or tray 21 so that said body can turn between a lowered closed position on the plate or tray and a raised open position and that, furthermore, it can be separated from the plate or tray itself.
  • the plate or tray 21 on its top face, near the front side, the plate or tray 21 has a groove 26 housing a profiled seal 27 and in parallel, on the back of the same, a transversal ledge 28, around all of which is assembled a first seal 29.
  • the ledge 28 can extend upwards from the bottom of a groove or from the top surface of the plate or tray until it exceeds in height the plane of the seal 29 that surrounds
  • the plate or tray 21 can in addition be equipped with lateral recesses 30 acting as gripper handles and/or a front grip.
  • a heat-sealing bar 31 On the lower face of the body 22, parallel to its front side are mounted a heat-sealing bar 31 and, on the back of this, a second seal 32 specular with regards to the first seal 29 held by the plate or tray 21.
  • the upper body 22 is also configured to enclose the usual functional components of the device generically indicated by 33 in Fig. 5 , such as a suction pump operated by a motor, the electric feed and control components of the functions of the device, plus the suction ducts starting from a facing suction opening 34 positioned inside an opening formed by the second seal 32.
  • the second seal 32 rests against and match with the first seal 29, forming between them a suction chamber 35 - Fig. 5 - that communicates with the vacuum pump by means of the suction opening 34.
  • the transversal reference ledge 28 then extends in said chamber 35, while the heat-sealing bar 31 matches with the profiled seal 27 on the base plane or tray 21.
  • the apparatus can be used in the usual way by placing the mouth of a bag containing the product to be preserved against the reference ledge 28 in the suction chamber 35 between the plate and tray base and upper body and by starting the suction and heat-sealing functions once the upper body is closed on the plate or tray base.
  • the base plate or tray and the upper body for example, means to enable the start of the suction cycle of the device only when it is closed and to start the heat-sealing function after the vacuum has been created in the bag can be provided.
  • a profiled seal 27 and a reference ledge 28 parallel between them are provided, with the addition of a linear seal 36 positioned parallel between those two elements 27, 28.
  • a basin 37 is provided to collect any potential substances released by the product during the packing phase and which can then be removed when the plate or tray are washed.
  • the ledge 28 acts as a reference for the positioning of the mouth of a bag that contains the product to be preserved, and when the device is closed the linear seals 32 on the upper body 22 interact both with the linear seal 36 and with the upper surface of the plate or tray base as shown in Fig. 10 , forming as suction chamber 35 to remove the air from the mouth of the bag to create a vacuum in the latter.
  • the base plate or tray 21 has, in its upper part, parallel from the front towards the rear, a profiled seal 27, a potential gripper rib 38 to hold the mouth of the bag, and a transversal rib 39 acting as a locator or guide of the mouth of said container or bag and having some interruptions or openings 40 for a downflow of any liquids from the upper plane of the to the rear collection basin 37.
  • the seal 32 supported by the upper body 22 rests directly on the upper surface of the plate or tray base 21 forming the suction chamber 35, while the transversal rib 39 is within the range of said chamber, as shown in Fig. 12 .
  • the base plate or tray 21 is like the one in Figs. 6 - 10 with the exception of the linear seal 36, which in this case is lacking, so it has a profiled seal 27, a reference rib 28 and a rear basin 37.
