The present invention relates to a tidy box suitable for keeping small items, for example office requisites such as pencils, pens, rubbers, and pocket calculators, small samples and small toilet and dress requisites. In preferred embodiments the box is especially designed to be fitted inside and to be secured to the back of the lid of a rigid type of case, such as an attache case, generally used for carrying documents.
Although there already exist boxes which can be used for this purpose, the present invention provides an improved form of tidy box which permits simple manufacture and which can have a high strength in use.
A tidy box in accordance with the invention, suitable for keeping small items, for example office requisites such as pencils, pens, rubbers, and pocket calculators, small samples and small toilet and dress requisites, is made entirely of polypropylene and consists only of two parts fitted together after moulding, one part, a lower part, forming the base of the box together with a lid having a catch or fastening lug on one side and a pull handle on the other side, the lid and the base being integrally connected by a polypropylene hinge so that the whole of said lower part constitutes only a single element, and the other part, an upper part, forms side portions, a top, back and front portion, the latter forming a fixed frame for the lid without any bottom cross-member, and the top having a notch and retaining edge, the whole of said upper part again constituting only a single element.
In preferred embodiments, as the tidy box will generally extend across the whole width of the lid of a case with which it is used, provision is usually made for dividing it up into several compartments with partitions formed simultaneously with the upper part, and the lower part then has several lids, one per compartment.
To provide a clearer understanding of the invention a description is given below with reference to the accompanying drawings illustrating, by way of non-limitative example only, a tidy box made in accordance with the invention and having three compartments.
In said drawings,
FIG. 1 is a general diagrammatic view of the tidy box;
FIG. 2 is a fragmentary view, on an enlarged scale, at hinge level with the box open;
FIG. 3 is a view similar to FIG. 2 but with the box closed;
FIG. 4 is an enlarged side view in vertical section of the box fitted in the lid of a case, the section being taken at the level of a fixing point;
FIG. 5 is a top plan view of the lower part of the box, with the lids thereof open;
FIG. 6 is a top plan view of the upper part of the box;
FIG. 7 is an enlarged side view in section taken on the line I--I of FIG. 6;
FIG. 8 is an enlarged side view in section taken on the line II--II of FIG. 6;
FIG. 9 is a further, fragmentary, top plan view of the lower first part;
FIG. 10 is a fragmentary underside plan view of the upper second part;
FIG. 11 is a fragmentary enlarged side elevational view from the end of FIG. 9;
FIG. 12 is a fragmentary enlarged side view in section taken on the line III--III of FIG. 9; and
FIG. 13 is an enlarged side elevational view from the end of FIG. 10.
Referring to the various FIGS. of the drawings, the upper part of the box structure illustrated therein is indicated generally by the reference numeral 1 and the lower part of the box structure, which includes a number of lids 3 for different compartments, is indicated generally by the reference numeral 2.
The upper part 1 incorporates a top portion 1a, a front portion 1b, a rear portion 1c and end portions or sides 1d. The lower part 2, which provides the base of the box in addition to the lids 3, incorporates a front base portion 2a, end or side base portions 2b, a rear base portion 2c, and a base surface or bottom portion 2d, these portions together forming a trough-like container.
In the case of a box with three compartments as illustrated, the lower part 2 is further provided with internal base portions 2e so that there are in effect three trough-like containers, and the upper part 1 has internal partitions 1e.
Referring more particularly to FIGS. 2 and 3, it will be seen that connecting hinges 4 between each lid 3 and the front base portion 2a of the lower part 2 are formed simply by an integral bridging section of polypropylene having a reduced thickness and bent round at the front permitting each lid to swing open through at least 90° (see FIG. 2). The lids 3 also each have a catch or fastening lug 5 and a finger pull handle part 6, and for engaging with the catch or fastening lug 5 the front portion 1b of the upper part 1 has a notch 7 in an upper retaining edge.
By referring to FIG. 4, the precise cross-sectional profile of the catch 5, pull handle 6 and notch 7 is seen, and the longitudinal shape of these elements is seen by reference to FIGS. 5 and 6. Thus, as shown, each catch 5 extends over only the centre section of the respective lid 3 and each notch 7 extends over only the centre section of the front portion 1b associated with each respective compartment, but on the other hand the pull handles 6 each extend along the whole length of their respective lids 3. From other structural details shown in FIGS. 4 to 8, it will be seen that the base or lower part 2, of which the front portion 2a is curved and inclined outwards, projects forwards beyond the front edge of the top portion 1a of the upper part 1 so that each lid 3, when closed, is inclined inwardly.
At each of at least two fixing points 8, as shown in FIG. 4, a hole 9 is provided in the base bottom portion 2d, extending inwards from the outside, for receiving a "Parker" screw 10 to fix the box to an attache case by passing the screw 10 through a side wall 11 of the lid of the case. The case is only partially illustrated, by this side wall 11 of the lid and by another wall 12.
In order to seat the box perfectly in the top of the case, abutment cross-members 13 are provided on the underside of the base bottom portion 2d and, on the upper part 1, feet 14 are provided at the bottom of the sides 1d together with an abutment cross-member on the rear portion 1c (see FIGS. 7 and 8).
As seen in FIG. 4, there is also a cross-member 16 behind the notch 7 forming an abutment or stop which prevents the lid 3 from being pushed in too far within the box. As is also seen in FIG. 4, the hinge 4 is formed with a portion which is sufficiently thin as to leave an open space or gap 17 between the lower edge 3a of the lid and the free edge of the front base portion 2a so as to permit lowering of the lid in the direction of the arrow 23 thereby to release the catch 5 from the notch 7.
Due to the upwards inclination of the pull handle 6, which arises partly from the opposite inclination of the lid 3 (in the closed position), when a pull is exerted to open the lid a lowering of the lid in the direction of the arrow 23 tends to be produced quite naturally.
Referring now to FIGS. 9 to 13, it is seen that in a preferred form the lower part 2, in the base side portions 2b and dividing portions 2e, includes openings 18 extending through or associated with feet 14 and forming mortise apertures which may act as sockets. Also, there are two support points 19 positioned at and rising above the outer wall, on the inside thereof, of the rear base portion 2c and a support member 20 positioned at and rising above the outer wall, on the outside thereof, of the rear base portion 2c (FIG. 11).
In this example, only two support points 19 are provided since there is also a support surface 21 provided by the fixing parts or portions 8 also positioned at and rising above the outer wall, on the inside thereof, of the rear base portion 2c.
In the upper part 1, each of the side portions 1d and interior partition portions 1e are provided with tenons 22 designed to be introduced into the mortice apertures 18.
Consequently, on the one hand the two parts 1 and 2 are fitted together by the arrangement of the tenons 22 and mortise apertures 18 and, on the other hand, the rear portion 1c of the upper part is held and supported between one side of the support member 20 and the other side of the support points 19 and the part 21 of the fixing points 8.
As the box is made in polypropylene, the two parts 1 and 2 can be positively joined together in a known manner by welding in fixing the tenons 22 in the feet 14 which, as indicated in FIGS. 11 and 12, will thereby be flattened.
The invention is not of course limited to the embodiment described and illustrated and it would not be outside the scope of the invention to make detail modifications in presentation and form, for example, in the covering of the box or in its interior fittings, a characteristic feature being that the box is made of only two parts each moulded all in one piece without using any mechanical accessories such as screws, fastenings, hinges, springs, rubber bands, etc.
