Abstract
Description
- The invention relates to sealable multicompartment containers and particularly to multicompartment food or drinks containers.
- Various products, including some food and drink products, are sold in packaged form with more than one component held in sealed isolated compartments prior to use and which are required to be mixed at the time of use. In the food and drink industry such products include various dairy products such as flavoured drinks or yoghurts. In other industries multiple chemical components may be held in sealed separate compartments up till use such as for example adhesive products where mixing is required prior to use.
- It is an object of the present invention to provide an improved multicompartment container which may be formed with more than one compartment which may store constituents in isolation when the container is sealed but which may be adapted by change of shape after opening in order to provide a single container in which the constituents are mixed.
- The invention provides a sealable multicompartment container having a first inner compartment surrounded by a second outer compartment each compartment having perimeter walls with upper edges of the walls of each compartment terminating in a closure plane with sealing regions on the upper edges for engaging with a closure lid to provide sealing of the container and isolation of each of the compartments, an outer perimeter wall of the first compartment and an inner perimeter wall of the outer compartment being formed by a folded wall member which is pliable to permit unfolding by pulling the inner compartment relative to the outer compartment, when the lid is removed, in a direction away from said upper edges so as to extend the container depth and cause the outer and inner compartments to merge into a single compartment.
- Preferably the second compartment forms an annular trough around the first compartment.
- Preferably the first and second compartments have perimeter walls which are circular and concentric with each other at their upper edges.
- Preferably the upper edges of the perimeter walls are formed with flat regions of sufficient area and rigidity to permit bonding in abutment with a sealable lid.
- Preferably the inner and outer compartments are of similar depth when the container is not extended.
- Preferably the inner perimeter wall of the outer compartment is formed of flexible corrugated sheet material.
- The container may conveniently comprise a food or drinks container in which the inner compartment comprises a tub for containing food or drink and the outer compartment provides a receptacle for other food or drink which is held separately in the container when the container is sealed but which mixes or merges with the food or drink in the inner compartment when the lid is removed and the container extended to merge the compartments.
- The container may be formed of plastics material.
- The invention includes a container as aforesaid in combination with a lid in sealed engagement with the upper edges of the perimeter walls to close the container and isolate said first and second compartments.
- The lid may comprise aluminium foil or a plastics film releasably bonded to the upper edges of the perimeter walls.
- The above container is conveniently made as a single unitary structure with the lid comprising a separate element.
- FIG. 1 is a side view in section of a multicompartment container in accordance with the present invention in a sealed condition,
- FIG. 2 is a plan view of the container with the lid removed, and
- FIG. 3 is a side view in section with the lid removed and the container extended in depth in order to provide a single tub cavity.
- The example shown in the drawings is particularly adapted for use in the food or drinks industry and may be conveniently used for products such as yoghurt or dessert products in which more than one constituent is held in isolation in the sealed condition but mixed on use.
- The example shown in FIG. 1 comprises a central tub or
pot 11 having an annularperipheral wall 12 formed integrally with aflat base 13. Thewall 12 tapers inwardly towards thebase 13 and is open mouthed at the top with a circular shape in plan as shown in FIG. 2. Thetub 11 forms an inner compartment which is surrounded by anannular trough 15 extending entirely around theinner tub 11 and forming an outer compartment. Thetrough 15 has an outerperipheral wall 16 which in this example is a substantially vertical wall. It also has an inclined innerperipheral wall 17 formed as a flexible corrugated sheet which forms part of a folded structure with the outerperipheral wall 12 of theinner tub 11. Theouter trough 15 is also open mouthed at its upper end and has the same depth as theinner tub 11. In this way thebase 13 of the inner tub and the bottom of thetrough 15 lie in the same plane and thereby rest in a stable manner when stacked or on a flat surface. Theperipheral walls outer trough 15 as well as theperipheral wall 12 of theinner tub 11 are formed as a single moulded sheet which has anoverhanging lip 19 around the entire container. - The
peripheral walls sealing surfaces 20 on which aflat lid 21 sits in sealing engagement. Each of thesealing surfaces 20 is sufficiently wide, as shown in FIG. 2, and sufficiently rigid for thelid 21 to be pressed into sealing engagement with the top of the container and bonded thereto so as to seal in an isolated manner contents in theouter trough 15 and contents in theinner tub 11. - In the sealed conditions shown in FIG. 1 the overall container has a depth indicated by that of the
inner tub 11. When thelid 11 is peeled away from the top of the container thereby breaking the seal with thesealing regions 20, the container may be pulled to a different shape in order to increase its depth and merge theouter trough 15 with theinner tub 11. Thewalls surface 20 at the upper part of thewall 12. When thetub 11 is pulled downwards relative to theouter walls 16 of thetrough 15, the folded wall structure may be progressively unfolded by the fold line progressively moving down the wall marked 17. That is thepliable wall 17 which in this example is corrugated in order to provide increased flexibility and flow around the fold line at the junction between theouter trough 15 and theinner tub 11. This movement may be continued until the position is reached shown in FIG. 3 in which thewalls inner compartment 11 and theouter trough 15. - It will be seen that the pot after extension in this way has a depth which is between two and three times the depth in the closed and sealed condition.
- It will be appreciated that when used as a food container, the
central tub 11 may be used for liquid or dry products. For example it could contain yoghurt or for example dry cereal. Theouter trough 15 may be used for liquid sauces or for milk. - When used for food or drinks products, the container may conveniently be made of plastics material such as for example polypropylene. Alternatively waxed board or waxed paper may be used. The lids may be made of various materials such as for example aluminium or polypropylene foil or alternatively paper lids may be sealed against the container.
- The material used for the container and the lid will be selected in accordance with the nature of the product to be held in the container.
- The nature of the material and thickness used to form the walls of the container will be such that the walls are flexible enough to allow ease of movement between the sealed and extended positions while the external wall will be rigid enough to provide support for the entire structure when extended. The materials used may be adapted to withstand chilling or microwave treatment.
- The invention is not limited to the details of the foregoing example. Although the particular example is shown where the two compartments are arranged concentrically one around the other, other designs may be used. The relative heights of the inner and outer compartments as well as their relative widths may be varied to suit the volume ratios required of the different constituents which are required in the container.
- In the example shown in the drawings, the upper edges of the
walls - The preferred example described in the drawings has a shape which allows the containers prior to filling and sealing to be stacked in a nested manner one extending inside another but other shapes may be used where necessary.
