Definitions

  • the invention relates to a container lid comprising a rim portion for connecting the lid to the container and a middle portion lying inside said rim portion and being movable in the axial direction relative to the rim portion.
  • a lid of this type is known in various forms.
  • the middle portion of the lid is joined to the rim portion via an intermediate portion having a plurality of concentric ridges and grooves.
  • the middle portion may be forced downwardly in order to press air out of the container. The air can escape from the container by passing between the rim portion of the lid and the container. After the downward force on the middle portion is released a partial vacuum is created in the container and the lid is sealed in place.
  • the packing For some products, such as foodstuffs, it is often necessary for products in the packing to be subjected to heat treatment, such as sterilization. If in such cases the packing consists of a container closed by a lid, the lid is usually of metal or sometimes of glass or other material and is for example fitted on the container by a screw connection. In order to obtain hermetically sealed packing after the heat treatment, a sealing ring of rubber or rubber-like material is placed between the lid and the container.
  • the container it is necessary for the container to be non-deformable in view of the fact that after the heat treatment a considerable negative pressure will be produced in the packing through the contraction of the contents and the condensation of the water vapour which drove the air out of the container during the heat treatment.
  • the packing must be able to withstand this negative pressure without being deformed, since a deformed packing has an unattractive appearance and therefore is difficult or impossible to sell.
  • the containers are therefore often made of glass or metal. This means that the packing is relatively expensive and in addition fairly heavy.
  • the packing may be provided with means for varying its inside volume.
  • a lid of the above-mentioned type could be used.
  • this type of lid is still relatively rigid and the distance over which the middle portion of the lid may be moved is relatively small. Consequently, the possible variation of the inside volume of a container closed by such a lid is relatively small. This means that during heat treatment a certian portion of the expanding gases in the packing have to escape from the packing by passing between the rim portion of the lid and the container.
  • a container closed by a lid of the abovementioned type presents almost the same disadvantages as a container closed by a screw cap. Also in this case the container must be made of a rigid material such as glass or metal.
  • the invention now seeks to provide a lid of such a type that the container can be made of a modern packing material of slight wall thickness and a relatively low modulus of elasticity, which on the one hand has a relatively low resistance to deformation but on the other hand is light and easily worked, while its price is advantageous.
  • a lid of the type defined above which is characterized in that the middle portion is joined to the rim portion via a bellows-shaped intermediale portion extending substantially in axial direction.
  • the heating of the contents of a container closed by the lid causes the bellows to expand, whereby the inside volume of a packing is increased, while on subsequent cooling the bellows is redeformed in the opposite direction through the contraction of the contents of the packing.
  • the average diameter of the bellows-like intermediate portion advantageously decreases from the rim portion in the direction of the middle portion, so that on the one hand the lids can easily be stacked without their unstacking in the packing machine causing any disturbance, while on the other hand the stacking of filled packings is also easily possible.
  • the bellows-shaped intermediale portion may have helical ridges and grooved in order to make it more easily deformable in axial direction.
  • the middle portion may have substantially the shape of a cone having an obtuse apex angle or of a truncated cone.
  • the lid may have a certain signal action.
  • the rim portion may be at least partly provided, on the side which comes into contact with the container, with a layer which can adhere to the material of the container, this layer preferably consisting of a plactics composition meltable through the action of heat and/or pressure.
  • the invention likewise relates to a packing consisting of a container and lid according to the invention.
  • the lid is preferably joined to the container by welding or be means of an intermediate layer applied to the rim portion of the lid and adhering to the material of the container, such as a plastics composition meltable through the action of heat and/or pressure.
  • the packing may be provided with a closable opening, which is preferably provided in the lid, for the purpose of allowing the escape of any larger amounts of gas formed during the heat treatment of the packing.
  • This opening is advantageously adapted to be closed by means of a drop of a meltable plastics composition.
  • the lid according to the invention will have a certain signal action. As the expanding gases and gases formed in the packing during the heat treatment will escape through the opening the pressure inside and outside the packing will remain the same during the heat treatment.
  • the embodiment of the lid 1 according to the invention which is shown in Figures 1 and 2, comprises a rim portion 2 and a middle portion 3.
  • the rim portion 2 is intended for joining to a container.
  • the middle portion 3 is joined to the rim portion 2 via a bellows-like intermediate portion 4.
  • the middle portion is thus movable in the axial direction relative to the rim portion 2.
  • the average diameter of the bellows-like intermediate portion 4 decreases from the rim portion 2 in the direction of the middle portion 3.
  • Figure 3 shows a filled container 5 which is closed by the lid 1 described above.
  • the rim portion 2 of the lid is completely joined to a top rim portion 6 of the container 5.
  • the lid 1 is fastened to the radially extending top rim 7 of the container 5 by welding or by means of an intermediate layer 8 adhering to the rim portion 2 of the lid and to the material of the container.
  • This intermediate layer 8 may consist of a plastics composition which is meltable through the action of heat and/or pressure, and which can be applied to the bottom face of the radially extending part of the rim portion 2 of the lid during the production of the latter.
  • the container 5 can be made of light material, such as plastics material.
  • the container 5 can be almost completely filled.
  • the lid may be provided with a closable opening 9. Closure can be effected with the aid of a drop 10 of a plastics composition meltable through the action of heat, this material being liquid during the heat treatment, so that gas can escape, and being solid at temperatures below the heat treatment temperature.
  • Figure 4 shows a lid in which the bellows-like intermediate portion 4a has helical ridged and grooves. This makes the intermediate portion more easily deformable in axial direction. It also facilitates the removal of the lid from the mould for forming the lid, particularly when the lid is formed by thermoforming. By rotating the lid it may be removed from the mould.
  • the lid of figure 4 is otherwise similar to the lid shown in Figure 1.
  • FIG. 5 shows a lid in which the average diameter of the bellows-like intermediate portion 11 is constant over practically the entire height. This lid is otherwise similar to the lid shown in Figure 1.
  • the lid shown in Figure 6 is provided with a middle portion 12 in the form of a cone having an obtuse apex angle. This middle portion 12 itself is likewise movable in the axial direction and has two stable positions.
  • the conical middle portion 12 is joined via a bellows-like intermediate portion 14 to the rim portion 2.
  • the lid shown in Figure 4 has a middle portion 13 in the form of a truncated cone, which also has two stable positions.
  • the middle portion 13 is joined via a bellows-like intermediate portion 14a to the rim portion 2.
  • the lids shown in Figures 6 and 7 may also be provided with a closable opening, which may be closed by a drop of a plastics composition meltable through the action of heat.
  • the conical or frustoconical middle portion 12 or 13 respectively thus has a signal action.
  • expanding gases and gases formed in the packing will escape through the opening 9, while the pressure inside and outside the packing will remain the same.
  • a negative pressure will be produced in the packing through the contraction of the contents of the packing and the condensation of water vapour which drove the air out of the packing during the heat treatment. If the packing is correctly closed, the portion 12 or 13 will be drawn inwards, after the heat treatment, because of the negative pressure produced in the packing. If the packing is not correctly closed, no negative pressure will be produced after the heat treatment, and the middle portion 12 or 13 will stay in its original position. In the event of inadequate heat treatment of the contents of the packing, the negative pressure in the packing will disappear through the action of bacteria, so that middle postion 12 or 13 will move outwards. Thus, practically all possible defects of the filled and closed packing will be signalized.
  • lids according to the invention with a flat middle portion and provided with a closable opening may have such a signal action.
  • the signal action of the lids of Figures 6 and 7 is better visible.
  • the upstanding part of the rim portion 2 may be provided with one or more annular ribs 15 fitting into corresponding grooves 16 in the wall of the container 5 when the lid is fitted to the latter.
  • a lid having a bellows-like intermediate portion according to the invention it is thus made impossible for large differences in pressure to occur in a packing consisting of a container closed by the lid according to the invention during the heat treatment of the packing.
  • the packing need be resistant only to low positive or negative pressures, so that the container and also the lid can be made of a modern packing material, such as a plastics material. This material is light and easily worked, and its price is favourable.
  • the packing with the lid according to the invention has another advantage, particularly when the lid is provided with a closable opening. After the heat treatment the space between the product in the packing and the lid will be very small because of the negative pressure in the packing. Consequently, it will be possible to obtain a stack of filled packings with very little empty space and the transportation and storage costs will be less than with common packings.
  • the lid according to the invention can obviously however also be used in combination with containers of rigid material, such as glass.
