This application is a National Stage application of International Patent Application No. PCT/IB2020/057892, filed Aug. 24, 2020, the disclosure of which is incorporated herein by reference in its entirety.
The present invention pertains to a plastic container having a lid for the transport and storage of goods, where the lid comprises two parts each attached by a hinge to opposite upper rims of the container. Furthermore, it pertains to containers of this kind that are stackable when closed and stackable or nestable when opened.
Such containers are commonly used and well known. For example, a container as disclosed in WO2015/104521 comprises a bottom, four side walls extending upwardly from the bottom, and two lid halves arranged by means of a hinge on the upper rim of opposite sidewalls. The lid halves may be pivotably rotated about the hinge from an open position, where they hang along the outside of the sidewalls, to a closed position. In the open position such containers may be stacked and nested within each other. In the closed position the free ends of the two lid halves each having corresponding contours interlace with each other forming a continuous, level surface over the open end of the container. As such, closed containers may be stacked.
A container with similar lids for closing is disclosed in CA 02863692.
It is the object of the present invention to provide a stackable container of the afore-described type, which allows the placement of flexible receptacles such as sacks or bags to sub-divide the interior volume of the container.
According to the invention a plastic container is provided having a bottom and four sidewalls extending upwardly from the bottom to an open end of the container and a lid comprising two lid halves each attached to the upper rim of sidewalls opposite from each other by means of a hinge. The two lid halves are pivotably rotatable about the hinge from an open position to a closed position, where in the closed position the two lid halves form a level and continuous surface over the open end of the container.
The two lid halves having an inner surface, which face the interior of the container when they are in their closed position, each comprise one hook on said inner surface and arranged adjacent to the hinge of a lid half, or two or more hooks arranged in a row adjacent to and along the hinge of a lid half. Each hook comprises a hook body extending essentially parallel to and spaced apart from the inner surface of the lid half.
In a preferred embodiment of the invention, the hook body of each hook comprises a recess having an opening on a side of the hook body, which faces away from the hinge of the lid half and toward the distal end of said lid half. The recess features in particular a two-sided undercut.
In a particular embodiment of the invention, the angle of the undercuts relative to the lateral sides of the lid halves may range from 45° to 90°. In the case of an angle of 90° the recess comprises a shape of rectangle. In the case of an angle of approximately 45° the recess comprises a shape approximating a triangle.
The recess with undercuts of each hook body provide a hook function and allow the placement of a strap or handle of a bag or sack having two such straps or handles inside a container with open lid halves. The open lid halves can hang approximately alongside the outer side of the container's side walls either vertically or at some angle to the sidewalls. A first strap of the bag is anchored in a pair of hooks of a first lid half, and a second strap of the bag is anchored in a pair of hooks on the second lid half opposite the first lid half. The straps can thus be anchored on opposite sides of the container such that the sack or bag is held open and items may easily be placed inside.
Preferably, three or more hooks are arranged adjacent and along the hinge of each lid half. Thus, several sacks or bags may be arranged next to one another inside the container, where each bag is fully extended and its upper end held open. A first bag may be placed in the container using a first pair of hooks on each lid half. A second bag may be placed using a second pair of hooks. The second pair of hooks may consist of one of the hooks of the first pair of hooks and a further adjacent hook. Thus, bags may be placed immediately next to one another without any gap between each other. In this configuration, a given hook holds a strap of one bag in one of its undercuts and a strap of a second adjacent bag in the other of its two undercuts.
In a further embodiment of the invention, each hook body has no recess but a rectangular shape extending from the hinge towards the free or distal end of the lid half where said hook is arranged.
In a further embodiment of the invention, each hook body has a width, when measured parallel to the hinge of the lid half, which increases with distance from the hinge. For example, such hook has a shape approximating a triangle.
In a further embodiment of the invention, the hook body has the shape of a T, where the bottom, narrow end of the T is adjacent to the hinge and the top, wide end of the T is at the free end of the hook body.
When the hooks of the plastic container have hook bodies of rectangular shape, T-shape or a shape increasingly broad towards its free end, straps of bags or sacks may be placed by looping the straps about the hook bodies from either side.
A container according to the invention with bags arranged in any manner described above may be closed by pivotably rotating both lid halves about their hinges into their closed position. Due to the two-sided undercut of the recesses in the hook bodies, the straps held by pairs of hooks remain attached when the lid halves are pivoted closed as well as when they are again opened.
The container according to the invention may be used by shoppers intending a large shopping requiring multiple bags or similar receptacles. In order to easily and simultaneously fill several bags with different items, a container according to the invention may first be placed on a shopping push cart or preferably shopping push platform where bags or sacks are arranged in the above-described manner using the said pairs of hooks on the lid halves. Shopping items are placed in the several bags and the lid halves are then closed to form a level surface on the container top. A further container according to the invention may be placed on top of the first container and again provided with several bags using the hooks to latch the straps around such that the bags are open and may filled with further shopping items. By this manner, several containers, each with neatly arranged bags with shopping items may be filled, where the bags always remain neatly attached, independently of whether the container is closed or open. When done with the shopping, the customer opens the containers by rotating the lid halves into their open position where the straps are still in place and the bags neatly arranged. The customer can then remove the bags for further transport home.
In an embodiment of the invention all hooks in the row of hooks have a body with a recess with a two-sided undercut. Such row of hooks can have three or more hooks.
In a further embodiment of the invention the hooks at either end of a row of hooks and adjacent to a lateral side of a lid half have a body with a recess with just a one-sided undercut. These hooks require only a one-sided undercut as they need to only hold the strap of one bag or sack.
In a further embodiment of the invention, each lid half additionally comprises one or more openings arranged at the position in the lid half, where the one or more hook bodies are arranged, where said one or more openings are of the size and shape of the hook bodies and positioned immediately below the hook bodies.
The invention will be described in greater detail, by way of example, with reference to figures as follows.
The container 1 has a rectangular bottom 2, short sidewalls 3 and long sidewall 4a and 4b extending upwardly toward an open end of the container 1 and a lid for closing the container having a first lid half 5a attached to a first sidewall 4a and a second lid half 5b attached to the second sidewall 4b opposite the first sidewall 4a. The two lid halves 5a and 5b are each attached to the upper rim of the longer sidewalls 4a and 4b by a hinge 6a and 6b respectively. The
According to the invention, each lid half 5a and 5b comprises two or more hooks 7 arranged on the inner surface 5c, which faces outwardly when the lid half is open (as shown) and would face toward the interior of the container 1 when the lid half is in its closed position. In
The lid half 5b further comprises an opening 13 approximately of the extent and shape of the hook body 7′ and at the location of a hook body 7′ such that the hook body 7′ is visible through the lid half. This opening 13 is provided in connection with the production of container 1 and does not pertain to the function of the hook of holding bag handles.
