Abstract

A safe transportation case with retractable handle, consisting of a compact box with a - generally - rectangular parallelepiped shape, whose upper side (top) is open where a handle is mounted, which is moved depending on whether the case is suspended from the handle or not. The handle from the middle of the open side of the case where it protrudes comes to rest in the inner part of the case, either adjoining to the rear side of the case, or converting to a section of a parallel divider, where it does not protrude. The base of the case has, perimetrically or in between as well, identical to one another cut-outs (30) which correspond to the also identical to one another tabs (31) which the sides and any vertical dividers have at their tops, in order that the tabs of the top of an upright case fit into a number of cut-outs of the base of another identical and also upright case. This fit is achieved with the front side of the upper case being flush with the front side, or the rear side, or any side, or any vertical or parallel divider of the lower identical case.

Description

SAFE TRANSPORTATION CASE WITH RETRACTABLE HANDLE
The invention pertains to a compact case with a handle, intended for the safe - handy transportation, attractive packaging and storage of various products.
Certain articles - such as fragile glass bottles containing alcoholic beverages - require packaging specifications which ensure their safe transportation from the place of production, occupying the least possible space. The appearance of their content at the retail sales outlet, their handy holding by the buyer, their attractive appearance so that they can be offered as gifts and the practicality if they are to be stored in cellars for a long time. In spite of the good appearance, the use of modern materials and the elaborate ways of manufacture of the types of packaging known to this day, none of them fulfils all the required specifications and conse- quently a large number of bottles are dressed in different and composite types of packaging which, however, burden the cost of the product they contain. Moreover, they also burden the environment with the non-ecological materials which are used for their manufacture, such as plastic, over-varnished paper, etc.
The safe transportation case with retractable handle according to the present invention is appropriate to be made entirely of processed natural wood in the form of plywood. It consists of a compact case with a -generally- rectangular parallelepiped shape, whose upper side (top) is open where a handle is mounted. When the case is carried individually suspended from the handle, then the handle protrudes from the middle of the top of the case across it and when the case is placed in an upright or horizontal position, then the handle shifts to such a position as not to protrude from the top of the case and not to obstruct its filling or emptying with the product. The base of the case has, perimetrically or in between as well, identical to one another cut-outs which correspond to the also identical to one another tabs which the sides and any vertical dividers have at their tops, in order that the tabs of the top of an upright case fit into a number of cut-outs of the base of another identical and also upright case. This fit is achieved with the front side of the upper case being flush with the front side, or the rear side, or any side, or any vertical or parallel divider of the lower identical case. The retractable handle and the connection possibilities between the tops and bases of the cases allow the interlocking of a number of cases together which are thus safeguarded from an individual or collective shift or even fall when these are displayed or carried on a pallet.
An advantage of the safe transportation case with retractable handle according to the present invention is that it meets all the aforesaid packaging specifications for many products, such as those for fragile goods, because the connections and fittings of the case in combination with the qualities, the strength and the smooth surface of wood, make the case: (a) Functional, as its surfaces can have openings for aesthetic or for functional purposes, such as direct visual contact with the colour or label of the product it contains, (b) Ideal to render a complete aesthetic result, as it can be coloured or have deco- rative elements or advertising messages printed on all parts of its surface and with the use of all known methods such as silk-screen printing, pyrography, thermo- print, etc.
(c) Handy and friendly both to man and the environment and hence attractive to the consumer.
(d) Safe when individually transported or used for the product it contains, because it is highly impact resistant.
(e) Economical in terms of bulk transportation costs, since it takes up minimum space and -due to its durability- does not require additional protection (extra cases).
(f) Safe when transported in bulk on pallets, too, since it can sustain strong pressure and the cases as a whole can be connected and interlock one to another in such a way that any individual detachment is impossible, except for the cases of the top row which must be held together because they become detached if lifted or pushed from their top to the outer side of the pallet.
(g) Practical, because if the rear side of a number of cases is used as a base for the cases to be placed (horizontally) one on top of another, then access to each individual product (e.g. bottle) which these cases contain is easy.
The invention is described below with the aid of examples of its fitting in cases with a capacity of 5 different numbers of bottles and with reference to the attached drawings, where:

The safe transportation case with retractable handle according to the present invention consists of a compact box with a -generally- rectangular parallelepiped shape, whose upper side is open. The open part of the case is defined as the top and the side that is opposite to it is defined as the base. The one side of the case is defined as the front side and the side that is opposite to it is defined as the rear side, while the other two panels that are opposite to each other are defined as the sides. The distance between the top and base ends determines the height of the case, the distance between the two sides determines the length of the case, and the distance between the front side and the rear side determines the width of the case.
A divider or dividers may be placed in the case between and in parallel to the sides and these, like the sides, are vertical and adjoining to the front side, the rear side and the base of the case. These dividers are defined as vertical dividers (18). One divider or dividers may also be placed in the case between and in parallel to the front side and the rear side and these are adjoining to the dividers or to the sides of the case as well. These dividers are defined as parallel dividers (19).
The safe transportation case with retractable handle according to the present inven- tion has two main features:
1. The handle of the case (20), which consists of a single solid element and has a movable base, as its position changes depending on whether it is being used or not. At the lower part of the front side of the handle, at two horizontally opposite parts of it, it includes one parallelogram portion at either part which is defined as the guide of the handle (21). The two guides of the handle are identical to each other. Each guide has a length which depends on the thickness of the sides or of the dividers of the case where it is mounted and a height depending on the forces acting on the handle. The case is suspended from the surface of the top of each guide of the handle and in the middle of this surface a point is defined as "a" and the theoretical straight line which joins the two "a's" of each handle is defined as straight line "aa".
Each guide is an integral part of a portion or portions of the handle which have surfaces vertical to straight line "aa" (22). The distance between these vertical surfaces of a handle depends on the distance between the sides or the vertical dividers of the case which include the slotted paths of the guides of the handle. The guides of the handle work in two slotted paths, also identical to each other, which are either on the two sides of the case or on two of its vertical dividers, and which are at equal distances from the middle of its length.
When the case is carried suspended from the handle, then the latter protrudes from the top of the case with the straight line "aa" being near the top, across the middle of the width of the case and in parallel to the base of the case. This position of the handle is defined as the in-use position.
When the case is not suspended from the handle then: a) if the case does not include a parallel divider, its handle is adjoining to the rear side of the case, from the top of which the handle does not protrude. b) if the case includes one or more parallel divider(s), the handle becomes a section of the upper part of that divider which is in the middle or closer to the middle of the width of the case, from.the top of which the handle does not protrude either. From the upper part of the parallel divider against which the handle comes to rest, a portion is cut away approximately corresponding to the external perimeter of the handle which takes it up.
The above positions of the handle are defined as at-rest positions where the straight line "aa" of the guides is now nearer the base of the case and in parallel to the position where it was when the handle was in the in-use position.
The slotted paths start from the middle of the width of the case - near its top - from where: a) In cases with no parallel divider the slotted path follows a sloping descending course and along the width ends at the internal surface of the rear side of the case. b) In cases which include one or more parallel divider(s) which, however, are at a distance from the middle of the width of the case, the slotted path also follows a sloping descending course and along the width ends as an extension of the upper part of the parallel divider which is closer to the middle of the width of the case. The above slotted paths are defined as sloping paths (23). c) In cases which include a parallel divider which is in the middle of the width of the case, the slotted path follows a descending course and also ends at the middle of the width of the case, nearer to its base. The above slotted path is defined as vertical path (24), whose axis of symmetry is vertical to the base of the case, in the middle of its width. In cases with sloping or vertical paths which have at least one vertical divider along the length of their handle, the latter may have an additional slotted path (25) with a width depending on the thickness of the vertical divider of the case. This additional path is at the lower part of the front side of the handle, between two vertical parts of the handle and perpendicular to straight line "aa". In a case with a vertical slotted path for the guide of the handle which has an addi- tional slotted path (25), the vertical divider of the case in the middle of its width includes another vertical slotted path (32) which starts from the top of the vertical divider and has a width which depends on the thickness of the handle. The additional slotted path of the handle works together with the vertical path of the vertical divider of the case when the handle shifts from the in-use position to the at-rest position and vice versa.
The distance from the base of the end of each slotted path of the guide of the handle to the top of the case is the same as the length of the perpendicular from the middle of the straight line "aa" to the top of the handle plus the height of its guide. The upper part of each sloping and vertical path has a shape as that of the sides and small base of a trapezium (26). The small base of the shape is arced with a length depending on the thickness of the guide of the handle. The middle of the arc is nearer to the top of the case, it is at the middle of its width and coincides with point "a" of the guide of the handle when this is in the in-use position. The length of either or of both side(s) of the trapezium figure depends on the height of the guide of the handle. The above shape is provided in order that, at this part of the slotted path, the guide of the handle can tilt both ways and the case can swing in a flexi- ble manner in relation to its handle, even if stationary, when this is in the in-use position. The stationary axis of this movement coincides with straight line "aa" of the handle.
The slopes, curvatures and width of the remaining middle part of each slotted path, that is from the ends of the sides of the trapezium to the end of the slotted path of the guide, are intended for the smooth shifting of the handle from the in-use position to the at-rest position and vice versa. In the shifting of the guides of the handle, straight line "aa" moves parallel to itself.
In order that the handle - when in the at-rest position - be allowed to come to rest with its front side being perpendicular to the base of the case so that it does not obstruct the placement - removal of the products it contains, the following arrangements are made: a) When the case - across the body of the handle - does not include a vertical divider, then the slotted path of the guide of the handle at its end is vertical (27) to the base of the case. The width and height of this vertical part of the slotted path depend on the length and height of the guide of the handle. b) When the case - across the body of the handle - includes one or more vertical divider(s) then for each of these dividers one slotted path (28) is formed, which starts from their top in the direction of the base of the case. The length of the slot- ted path at its end depends on the thickness of the handle and is taken up by part of the handle when this is in the at-rest position.
In each case which does not include a parallel divider and its handle when in the at-rest position is adjoining to the rear side of the case, then at the rear side of the case a slotted path (29) is formed which starts from the central part of the length at its top in the direction of the base of the case. The distance from the end of this path to the top of the rear side of the case is bigger than the height of the central part of the grip of the handle in order that a gap be formed between the latter and the end of the path so as to facilitate the movement of the handle from the at-rest to the in-use position.
2. The bottom part of the case, which perimetrically or at intervals, too, has cut-outs (30), which are identical to one another, and correspond to the tabs (31), which are also identical to one another, which are at the tops of the sides and of any vertical dividers of the case, in order that the tabs on the top of an upright case fit into a number of cut-outs on the base of another identical and also upright case.
This fit is achieved with the front side of the upper case being flush with the front side, or the rear side, or any side, or any vertical or parallel divider of the lower identical case. The different ways of placing the bottom part of one case on the top of another identical case are provided because the width and length of the base of the cases is equal: a) either to the sides of a square which is defined as a square unit; b) or to the external outline formed by the sides of a number of identical square units which are in one or more row(s) and with sides which are adjoining to one another in such a way as to form a bigger square or a rectangle. The inner part of each side of all square units of the base of the cases has across it identical to one another cut-outs (30). Each of the four cut-outs included in each square unit has a width which corresponds to the thickness of each parallel and vertical, if any, divider (18) of the case, which are of equal thickness. In case bases consisting of two or more square units, the cut-outs of every two sides (of the square unit) which are adjoining are converted to one cut-out with the double width (32) in relation to the width of the cut-outs at the perimeter of the bases of the cases. The depth and length of the cut-outs of the base correspond to the height and length of the tabs (31) at the tops of the parallel and vertical, if any, dividers of the case.
The tabs of the case are identical to one another and are extensions of a section or sections of it at the top of the body of the sides and of the vertical dividers, if any - when these vertical dividers are across two adjoining sides of the square units of the case.
In this way if the base of one case consists of more than one square units, then each case can fit on and between the tops of a number of other cases (with equal square units) which are in a row and adjoining to one another in such a way that all together form a rectangular or triangular or pyramidal assembly.
The retractable handle and the different interlocking possibilities between the tops and bases of the cases ensure the rigidity and locking of a number of cases together which are thus safeguarded from any individual or collective shift or fall when the cases are carried on a pallet or displayed at the stores where they are sold.
