Abstract

A bag comprises a portable container, comprising an envelope with at least one opening, where at least part of the container is arranged to form a bottom and a back support. In this bag, the back support is hingedly provided in the container relative to the bottom, and the back support is arranged to be fixated relative to the bottom. In the bag, no external parts are provided at the outside of the bag. The back support may be a rigid rectangular plate-shaped member, hingedly connected at or near a short edge of the member to the bottom provided in the envelope. The plate-shaped member may be provided as part of the envelope or within the envelope as a distinct member. This applies to the bottom as well, noted that the bottom is not necessarily a rigid member; it may also be a part of an optionally highly flexible envelope.

Description

TECHNICAL FIELD

The various aspects of the invention relate to a container with a back support.

BACKGROUND

Back supports are often used when e.g. going to the beach or when having a picnic in the park to provide a more comfortable seating or lying position compared to sitting or lying in the sand or on grass supported by one's arms.
Portable back supports may be foldable to increase portability, but are still relatively large and require one full hand for carrying. The present invention comprises a combination of a foldable back support with a carrying container for e.g. food and/or drinks. In known combinations of a back support and carrying container, the back support is provided on the outside of the container with a large rigid frame.

SUMMARY

It is preferred to provide a more handy portable back support. An aspect provides a bag with foldable back support. The bag comprises a portable container, comprising an envelope with at least one opening, where at least part of the container is arranged to form a base, a bottom of the container in particular, and a back support. In this bag, the back support is hingedly provided in the container relative to the base, and the back support is arranged to be fixated relative to the base.
By providing the back support in the bag, no external parts are provided at the outside of the bag. The back support may be a rigid rectangular plate-shaped member, hingedly connected at or near a short edge of the member to the bottom provided in the envelope. The plate-shaped member - or other type of back support may be provided as part of the envelope or within the envelope as a distinct member. This applies to the bottom as well, noted that the bottom is not necessarily a rigid member; it may also be a part of an optionally highly flexible envelope.
An embodiment of the bag comprises an additional support. In this embodiment, the additional support is hingedly provided in the container relative to the bottom; and at least a part of the back support, at least a part of the additional support, and at least a part of bottom are arranged to form a closed shape.
In this embodiment, the bottom may be a flexible part of the envelope, for example the bottom of the bag. The back support and the back support may be provided in sidewalls of the envelope. Alternatively, either one of the supports or both are provided as distinct, preferably rigid and preferably rectangular plate-shaped members that are at or near their short edges hingedly connected at or near short edges of the bottom of the bag. Having said that, alternative implementations may also be possible for more specific implementation of this embodiment. An advantage of this embodiment is that with the supports folded down or otherwise folded away, preferably flush against the envelope, almost the full space within the envelope may be used for carrying goods and no external members are required. On the other hand, the back support may be conveniently set up for providing a back rest.
In another embodiment, the back support comprises one or more abutments, where the additional support is arranged to abut to for forming the closed shape. This embodiment allows to adapt the back rest to the desires of the user.
In a further embodiment, the back support is bendable such that the back support may form a curved shape such that the back support may be fixated relative to the bottom. Depending on the material used, an advantage of this embodiment may be that the back support may provide certain resilience which may be experienced as enhanced comfort.
Again another embodiment of the bag comprises a first compartment where at least part of the back support may be placed in and withdrawn from. A first advantage is that this allows to put the bag in the washing machine. Another advantage is that this allows the bag to be folded away in a very small package, without an optionally rigid back support member.

To provide a smooth surface on the back support 112, the top of the back support, opposite to the hinging connection, may be connected to the top of the bag 112, at this inside of the bag. The connection may be provided by means of a hooks-and-loops fastener or equivalent, by providing an envelope at the inside of the bag for receiving the top of the back support 112. The additional support may be connected to the inside of the bag in a similar way, at the opposite inside of the bag.
Figure 5 also shows a sheet 116 which may be used to form a lounge bed in combination with the bag 100 with foldable back support 112, where the sheet 116 is sufficiently large to provide cover from the ground for the person using the lounge bed.
Figure 6 shows the bag 100 with foldable back support 112 comprising an additional bag 117, which may be placed inside the container 110 and may be taken out of the container 110 following the direction of the arrows. The additional bag 117 may comprise an insulating material, as it may function as a cooler bag for insulating the contents of the additional bag 117, e.g. food and drinks, from the ambient temperature. The measurements of the additional bag 117 are preferably smaller then the measurements of the bag 100 to ensure that the additional bag 117 fits completely in the bag 100.
Figure 7 shows the bag 100 with foldable back support 112, comprising a first compartment 118 which may hold at least part of the back support 112 and is hingedly attached to the inside of the container 110, preferably to the bottom 113, a second compartment 119 which may hold at least part of the additional support 114 and is hingedly attached to the inside of the container 110, preferably to the bottom 113, and one or multiple abutments 115, preferably placed on the back support 112.
The first compartment 118 may comprise a first flap 120 which may be used to hold the back support 112 inside the first compartment 118, whereas the second compartment 119 may comprise a second flap 121 which may be used to hold the additional support 114 inside the second compartment 119. The flaps may be secured for closing the compartment by means of button-and-hole connections, hooks-and-loops fasteners or equivalent, zippers, other, or a combination thereof.
The first compartment 118 may provide the hinging functionality for the back support 112 with respect to the inside of the container 110, and the second compartment 119 may provide the hinging functionality for the additional support 114 with respect to the inside of the container 110.
Another embodiment of the bag with foldable back support is presented where the back support and/or the additional support comprise a material with high thermal capacity. When cooled to a temperature below ambient temperature, the back support and/or additional support may provide cooling capacity for the contents of the bag, which may be e.g. food or drinks.
Another embodiment of the bag with foldable back support comprises the container with a triangular shaped base, preferably a triangular based bottom, the back support with a triangular shape, and optionally one or more triangular shaped additional supports. The back support, part of the container, preferably the bottom, and optionally one or more additional supports may be locked with respect to each other such to place and hold the back support at an angle with respect to the bottom inside the container. Instead of being triangular shaped, the container base, back support and one or more additional supports may also be shaped as any other polygon.
In the embodiments discussed so far, the back support and the additional support have been discussed as being distinct from an envelope of the bag as a container. In other embodiments that may comprise any feature discussed above, at least one of the back support and the additional support are incorporated, either fixed or releasably, in a part of the envelope of the bag. Such part may be all or part of the bottom of the bag or a side part of the envelope of the bag.
