Patent Application
20070063051
The subject of this invention relates to a storage unit with identifying markings, consisting of a receptacle that encloses a storage area that receives the material to be stored, an opening in the receptacle leading to the storage area, and a closure member that may be secured temporarily over the opening.
In recent times, as packaging technology has developed, it has become increasingly common to associate the purchase of products packaged in storage units for distribution, such as beverages, with a contest for prizes. The essence of the competition is that a particular marking is placed at quite an inaccessible place on the storage unit, such as on the inside of the closure cap, so that it becomes visible only once the packaging has been opened. The purchaser can check whether he or she, has won a prize by examining the component of the packaging, such as the closure cap that bears the marking.
Other applications of identifying markings include those where data regarding the date of manufacture or other information relating to the packaging or content of the storage unit is indicated. Today, purchasers generally check this data by visual inspection, as in the previous example.
Two disadvantages of such solutions are that the examination of markings requires the expenditure of a significant amount of human work, and that there is a high probability of a mistake's being made in reading the markings, which may result in considerable loss or damage.
Another disadvantage is that the identifying markings must be located in various places depending on the particular objective. Thus, it is a good idea for prize identifiers associated with advertising objectives to be placed in a location that is difficult to access, while information used to identify goods must be placed so that is easy to detect. These different requirements demand different technologies, which increase manufacturing and packaging costs, and thus, indirectly, the price of the product to the consumer.
An example of the marking versions used at present is shown in U.S. Pat. No. 6,059,133, which involves the use of a certain marking system on the container cap of the bottle that forms a part of the overall storage unit, and the fixing of an accessory piece on the cap. This accessory element is a rotatable part-unit with a window, so that when the assembly is rotated, only a detail of the marking system is visible in the window at any particular point.
The basic disadvantages of this construction are that it is a complicated mechanism and that the fixing of the moving part in a particular place needs further steps in terms of manufacturing technology. Also any damage to the container cap will render the markings completely unidentifiable.
A further disadvantage is that it is difficult to recognise the markings appearing within the window because of the size of the container cap and the design of the marking system. In order for a machine to recognise the markings, the component that carries the markings must be turned in a particular direction, which makes reliable reading of the identifying marks even more problematic.
The patent specifications registered under U.S. Pat. Nos. 4,372,457 and 4,151,924 describe solutions that may be used for individual identification, but which are based on different fundamental principles. With these inventions the identifying marking is carried by a liner made from a material different from that of the closure cap, affixed to the interior of the same. The drawback to this solution is that the production of a separate liner to carry the identifying marking and the securing of this liner to the closure cap increases the manufacturing costs, as well as the number of steps employed, which in turn increases the overall production costs associated with the product.
Another disadvantage is that for caps that can be redeemed for prizes, the removable insert may be forged, raising numerous additional concerns related to illegal gains.
A further general drawback that applies to all identifying marks applied using known methods in or onto the components used to close or seal storage units is that in designing markings for protected places so that they cannot be accessed without damaging the, product packaging, many issues related to hygiene in regard of food industry products must be taken into account, a circumstance that further complicates the process of implementing an acceptable solution.
With the current invention, the objective was to create a storage unit with identifying markings that eliminates the deficiencies inherent in other solutions, is easy to manufacture and assemble, does not require alteration of the procedures and equipment used in conventional packaging technology and provides a method for creating appropriately protected identifying markings that cannot be forged and that can be machine-checked without any particular difficulty.
The present invention is based on the recognition that if we include particles of a marking material in or on the material of the storage unit whose random distribution produces a unique and irreproducible electromagnetic radiation image or response radiation image in the space surrounding the storage unit that is specific to the storage unit or a component of the same, then each particular radiation image may be used to identify a particular storage unit, and thus solves the task.
In accordance with the stated objective, the storage unit with identifying markings according to this invention, which is composed of a receptacle that encloses the storage area receiving the material to be stored, an opening in the receptacle leading to the storage area, and a closure member that may be temporarily fixed over the opening, and which is constructed so that the identifying markings are formed by a group of particles of a marking material which creates a unique electromagnetic radiation image or unique electromagnetic response image arranged in a random distribution over the surface of the closure member and/or within the material of the closure member and/or on the surface of the receptacle and/or within the material of the receptacle.
A further criterion that might be applied to the storage unit is that the wavelength of the electromagnetic radiation or the electromagnetic response radiation of the particles of the marking material used falls within a range of 0.71 nm to 3812 nm.
In one possible embodiment of the storage unit the state at least some of the particles of the marking material are solid and/or at least some of the particles of the marking material are not solid, e.g. liquid or an amorphous solution.
In another embodiment of the invention, the closure member includes a front portion, which seals the opening in the receptacle, and a contiguous body portion equipped with a joining surface that extends from the front portion, the identifying markings are applied to the front portion and/or to the contiguous body portion.
Another aspect of the present invention, the closure member is formed as a coverplate and the identifying markings are applied to the coverplate.
In yet another embodiment of the storage unit, the receptacle has a covering that forms a surface corresponding to a solid of revolution or has a covering that forms a prismatic surface whose base is a polygon.
The storage unit according to this invention offers numerous advantages. The most significant one of these is that given the special nature of the marking material particles, a specific identifying mark can be created for each and every storage unit that is random, irreproducible, and displays a radiation image characteristic of one and only one storage unit.
A further advantage is that the marking material particles used to create the identifying markings can be mixed into the material of the storage unit or can be applied to the surface of the storage unit using known manufacturing processes, so that neither the technology used to manufacture the storage unit, nor the packaging processes, nor the packaging equipment need be changed in order to produce this method for unique identification.
The resulting advantage is that the product may be produced and packaged using conventional technologies and equipment without substantially increased production costs, while at the same time a product of added service value is created when the storage unit according to this invention is used, which can be applied both to promotional activities designed to encourage product purchase and to identifying the given product for other reasons.
Another advantage is that the storage unit according to this invention offers a method for implementing irreproducible and protected identifying markings, such that machine checking may be accomplished without any particular difficulty, using existing equipment known in itself. In this way, the checking of identifying markings through visual inspection can be significantly decreased, which results in reduced costs and minimises the number of possible errors.
Another property that must be considered advantageous is that the use of particles of a marking material to produce the identifying markings makes it impossible to determine from the packaging whether a product involved in a promotion designed to encourage purchase will yield a prize, and thus definitively eliminates instances of abuse.
Yet another further advantage is that the particles of the marking material may possess special additional properties, such as fluorescence or phosphorescence, thus producing a visual effect under certain conditions that may be used to enhance the commercial success of the product packaged in the storage unit according to this invention.
In the following section of this document, the storage unit according to the present invention is presented in greater detail through example embodiments and drawings. In the drawings,
In
The particles of the marking material 31 and 32 that create the identifying markings 30 are to be found here in the material 15 of the closure member 10 and on the covering surface 14 as well. The difference is that in this case, during the course of production, the particles of the marking material 31 and 32 are mixed as a liquid colouring agent into the plastic granules that constitute the raw material from which the closure member 10 is made. In essence, in the course of manufacture, the colouring agent and raw material together form a solution. After the closure member 10 has been completed, the dissolved colouring agent appears in random distribution in the form of particles of the marking material 31 and 32 within the closure member 10, creating the given identifying markings 30 that characterise the closure member 10.
The particles of the marking material 31 and 32 that create the identifying markings 30 can be of a material that displays an image that, when illuminated using light of a wavelength in the visible range, can be detected by the human eye, or they may even be of a material for which ultraviolet (UV) or infrared (IR) light is necessary to make the particles of the marking material 31 and 32 of the identifying marking 30 detectable. In fact, it is conceivable that a fluorescent or phosphorescent marking material may be used. Naturally, the properties of the particles of marking material 31 and 32 that create the identifying marking 30 determine which procedure may be used to check and identify the closure member 10. The wavelength of the electromagnetic radiation emitted by the test device or the wavelength of the electromagnetic radiation test range of the measuring instrument must be selected so that it corresponds to the wavelength of the electromagnetic response emitted by the identifying markings 30. In any case, it is expedient to select the material that provides the particles of the marking material 31 and 32 that create the identifying markings 30 such that the possible wavelengths of the electromagnetic radiation of the particles of the marking material 31 and 32 or response radiation fall between 0.71 nm and 3812 nm.
Here it must be noted that the particles of the marking material 31 and 32 forming the identifying markings 30 may differ from one another even within a single closure member 10, both in terms of their material and in terms of their matter state. In fact, it is possible to produce an embodiment for which the identifying markings 30 are applied exclusively on the covering surface 14 of the closure member 10, while for another embodiment, they are found only within the material 15 of the closure member 10, and in a third case (as was described earlier by means of examples), they appear both on the covering surface 14 of the closure member 10 and in its material 15.
It should also be emphasised, that the identifying markings 30 are not necessarily only carried specifically by the closure member 10 of the storage unit.
One of the identifying markings 30 is situated on the covering surface 14 of the closure member 10 as a tamper-proof foil sheet 16, while the other is formed of particles of the marking material 31 and 32 embedded in the material 24 of the receptacle 20 and is visible on the covering surface 23 of the receptacle 20. The particles of the marking material 31 and 32 may be identical to those discussed in conjunction with earlier specifications.
The receptacle 20 possesses a covering surface 23 that forms a prismatic shape, which delimits the storage area 21 of the storage unit. The closure member 10 is positioned in the covering surface 23 allowing the opening 22 to be closed.
The particles of the marking material 31 and 32 applied over the covering surface 23 and within the material 24 of the receptacle 20 correspond with those described in relation to the closure member 10 in terms of their effect mechanism. Here, the identifying markings 30 may again be used for altering environmental electromagnetic radiation, either actively, meaning by emitting electromagnetic radiation of their own, or passively, by inducing an electromagnetic response. The wavelength range of the electromagnetic radiation or response here also falls between 0.71 nm and 3812 nm.
The storage unit according to this invention may be used effectively in all cases where packaged goods must be supplied, for whatever reason, with identifying markings that are unique, irreproducible and may be used for the purposes of inspection without the expenditure of extra human work.
