The present invention relates to an elongated package for a windscreen wiper device of the flat blade type.
The present invention also relates to a system comprising such an elongated package according to the invention, as well as two windscreen wiper devices of the flat blade type packaged therein.
A windscreen Wiper device of the flat blade type comprises an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, wherein ends of the wiper blade and/or of the longitudinal strip may be connected with a respective connecting piece, the carrier element biasing the wiper blade in a curved position, which windscreen wiper device comprises a connecting device for pivot ally connecting an oscillating wiper arm thereto near one end thereof. The longitudinal strip is usually referred to as a flexor, whereas the connecting piece is usually indicated as an end cap. The connecting device in practice is referred to as a connector. the wiper blade is preferably made by extrusion. Hence, the present windscreen wiper device is designed as a so-called “yokeless” wiper device, wherein use is no longer made of several yokes pivotally connected to each other, but wherein the wiper blade is biased by the carrier element, as a result of which it exhibits a specific curvature.
It is noted that the present invention is not restricted to the use of only one longitudinal strip forming the elastic carrier that is particularly located in a central longitudinal groove of the wiper blade. Instead, the carrier may also comprise two longitudinal strips, wherein the strips are disposed in opposite longitudinal grooves of the wiper blade, the groove(s) may be closed at one outer end.
Further, it is noted that in practice use is made of a mounting head fixed for rotation to a shaft, wherein the shaft is rotatable alternately in a clockwise and in a counter-clockwise sense carrying the mounting head into rotation. Thus, in turn the mounting head draws the connecting device into rotation and thereby moves the wiper blade. In the alternative, the mounting head is fixed for translation to a carriage, wherein the carriage can be translated alternately in a one linear direction and in another counter linear direction carrying the mounting head into translation. The present windscreen wiper device can therefore he used circular or linear movement of the mounting head.
Such an elongated package is generally known.
One drawback of this known package is the fact that due its specific curvature the windscreen Wiper device thereof cannot be inserted easily in the package, whereas once the windscreen wiper device is taken out the package it cannot be handled easily, for example in an outlet for display purposes. A further disadvantage is that it is expensive and cumbersome to make use of two packages for packaging two windscreen wiper devices with wiper blades having different lengths for a car.
The object of the invention is to overcome the drawbacks of the prior art as mentioned above, in particular to make it possible that the windscreen wiper device can be efficiently held during transport, storage and display.
In order to accomplish that objective, an elongated package of the kind referred to in the introduction is characterized according to the invention in that the package comprises two sleeves being interconnected along their length, wherein each sleeve is arranged to hold a windscreen wiper device of the flat blade type, wherein walls of each sleeve enclose an acute angle, the angle is preferably smaller than or equal to 45°. Thus, the sleeves are each shaped such that a windscreen wiper device of the flat blade packed therein is supported along its connecting device and/or its longitudinal strips and/or its connecting pieces, while a wiping lip thereof rests free inside towards a vertex of the respective sleeve (i.e. is not engaged by the walls of the respective sleeve). Thus, the present invention avoids that the wiping lip is in contact with its corresponding sleeve. The present package allows packaging two windscreen wiper devices in the sleeves, so that particularly two windscreen wiper devices with wiper blades having different lengths for one car can be efficiently transported, stored and displayed in one package. Further, as the sleeves each have walls enclosing an acute angle preferably smaller than or equal to 45°, the windscreen wiper devices are supported inside the chambers at the location of their connecting devices and/or the connecting pieces, for example, without damaging a longitudinal wiping lip of the wiper blade thereof. Thus, the wiping lip is not engaged by the package and rests free inside the package. Wiping properties are therefore not negatively affected h using the package for transport, storage and display.
Particularly, the sleeves are interconnected along their entire length.
The package is preferably made from one blank.
It is noted that the present elongated package enveloping the two windscreen wiper devices is used without any further packages, so that the present package solely acts as holder during transport, storage and/or display.
In one preferred embodiment of an elongated package in accordance with the invention the walls enclosing the acute angle are facing towards the interconnection of the sleeves. In the alternative, the walls enclosing the acute angle are facing away from the interconnection of the sleeves.
In another preferred embodiment of an elongated package according to the invention the package is mirror symmetrical relative to a vertical median plane thereof. Hence, in both sleeves the walls enclosing the acute angle are facing towards the interconnection of the sleeves or facing away from the interconnection of the sleeves. In the alternative, the package is non-mirror symmetrical relative to a vertical median plane thereof. Thus, in one sleeve the walls enclosing the acute angle are facing towards the interconnection of the sleeves, whereas in the other sleeve the walls enclosing the acute angle are facing away from the interconnection or the sleeves.
In another preferred embodiment of an elongated package in accordance with the invention the walls enclose an acute angle smaller than 40°, preferably smaller than more preferably smaller than 30°.
In another preferred embodiment of an elongated package according to the invention the package comprises a weakening line at the location of the interconnection of the sleeves, the sleeves can thus be easily separated from each other by hand.
In another preferred embodiment of an elongated package in accordance with the invention the sleeves are bend towards each other, wherein the sleeves are interconnected along walls thereof. A more compact package is thus obtained for efficient transport,
The package according, to the invention particularly comprises a suspension hole to enable storing the package in vertical (suspended/banging) position, the sleeves are preferably printed or labelled in order to indicate applications of the packaged wiper blades and/or to contain advertising.
As indicated, the present invention also refers to a system comprising an elongated package according, to the present invention, as well as two windscreen wiper devices of the flat blade type, wherein one windscreen wiper device thereof is held by one of the sleeves, and wherein the other windscreen wiper device thereof is held by the other of the sleeves. Particularly, a wiping lip of each windscreen wiper device of the flat blade type is facing towards the acute angle.
The invention will now be explained in more detail with reference to Figures illustrated in a drawing, wherein:

With reference to
Hence, the windscreen wiper devices 15,16 are supported inside their corresponding sleeves 13,14 at the location of its connecting device 7 and/or its connecting pieces 6, and so that a wiping lip 21 of the wiper blade 2 thereof is not engaged at all. The wiping lip 21 rests thus free inside the sleeves 13, 14 and cannot he damaged during transport, for example. As shown, the package 12 is mirror symmetrical relative to a vertical median plane perpendicular to the interconnection region 17 thereof. This is also the case in another preferred embodiment (not shown), wherein the walls 19,20 enclosing the acute angle a face away from the interconnection region 17 of the sleeves 13,14, i.e. at the location 22, the package 12 is non-mirror symmetrical relative to the vertical median plane thereof in case one of the sleeves 13 has the acute angle α towards the interconnection region 17 and the other of the sleeves 14 has the acute angle α away from the interconnection region 17, that is at the location 22.
