Patent Application
20150217890
The present invention relates to the sealing of packages, cartons or parcels, and more particularly to a hand-held handle dispenser for forming a handle for carrying these packages.
Current hand-held adhesive tape dispensers commonly used for parcel wrapping and closure, do not provide the ability to the user to add a handle to the parcel being closed. To add a handle to the parcel, a user has to place an “external” pre-manufactured handle, or some other “external” ad-hoc handle.
Such a solution requires different pre-manufactured handle models to fit with different parcel sizes. This creates logistics and storage difficulties, in addition to is the second separate step in affixing the pre-manufactured handle following on the wrapping and closing of the parcel.
Another solution is to use a specific box with prepositioned holes made as handles. Such a solution suffers drawbacks. Indeed, customers often prefer to avoid holes in the package to secure the integrity of the content and so that the interior of the parcel cannot be seen. Moreover, the creation of these holes is an additional cost and may be the cause of a deterioration of the parcel.
The object of the invention consists therefore in overcoming the above drawbacks. Another object is to give the user the ability to make handles of various lengths depending on the parcel size and shape.
These objects are achieved by providing a handle distributor incorporated in a hand-held adhesive tape dispenser to constitute a hand-held handle dispenser for affixing both the tapes and the handles.
By locating the handle distributor on the hand-held adhesive tape dispenser, there is no need to search for and choose an “external” handle from a selection of “external” pre-manufactured handles of different sizes. The handle is added to a fully closed parcel without the need for holes/openings in the parcel and it reduces significantly the cost of using such external pre-manufactured handle. Moreover, the user can place the handle(s) where it is most appropriate with regards to the parcel and its contents.
According to a feature of the invention, the cartridge is arranged to store pre-cut insert strips and in that said transport and affixing means comprises transport/selection rollers for conveying one by one the pre-cut insert strips from the cartridge to said application roller and a trigger for controlling said transport/selection rollers and initiating the affixing of a first pre-cut insert strip.
Preferably, in order to create a long strip corresponding to a particular handle length, a second and further pre-cut insert strips are dispensed just after the first one.
According to another feature of the invention, the cartridge is arranged to store pre-cut insert strips and in that said transport and affixing means comprises a pusher button actionable by a user to slide the cartridge horizontally relative to the main frame in order to bring the uppermost pre-cut insert strip against the adhesive tape and a spring to slide back the cartridge to its rest position when the user releases the pusher button, thus separating the uppermost pre-cut insert strip from the other remaining in the cartridge.
Advantageously, a pre-cut insert strip is formed by a thin strip of paper approximately 45 mm×205 mm with a non-printed side coated by a thin film of plastic of same dimensions.
According to yet another feature of the invention, the cartridge is arranged to store an insert strip roll, and said transport and affixing means comprise a trigger acting against a spring mechanism for initiating the affixing of the insert strip and for stopping the dispensing from said insert strip roll by cutting the insert strip.
Preferably, the cutting of an insert strip of determined length is performed via a presser acting on a knife for stopping the dispensing from said insert strip roll.
In an alternative embodiment, the insert strip roll includes perforated separating lines, which are regularly spaced along the insert strip of the roll at a distance that is equal or slightly less than the distance between the blocking point for the dispensing from the insert strip roll and the point of contact of said insert strip roll with the adhesive tape.
Preferably, the cutting of an insert strip of determined length is performed via a presser blocking the dispensing of said insert strip roll.
The invention also concerns a method for dispensing a handle with the above hand-held handle dispenser comprising the following steps:
When the cartridge is arranged to store an insert strip roll, stopping the affixing of said at least one first insert strip dispensed by said insert strip roll is made by cutting said insert strip roll via a presser blocking or acting on a knife for stopping the dispensing of said insert strip roll.
Advantageously, the affixing of the second adhesive tape on the parcel is made onto a determined length of the first adhesive tape already used for closing the parcel.
Other aspects, features and advantages of the present teachings will become clearer to those ordinary skilled in the art upon review of the following description of a specific preferred embodiment of the invention in conjunction with the accompanying drawings where:
The hand-held handle dispenser according to the invention not only operates as a hand held adhesive tape dispenser commonly used for parcel wrapping and closure, but also provides the ability for the user to add a handle to the parcel being closed. To this end, it is proposed to create, in a standard adhesive tape, which is regularly used for closing parcels and provided by a hand held adhesive tape dispenser, a non-adhesive zone within the length of this adhesive tape by attaching on the adhesive part of the tape an insert strip provided from a handle distributor incorporated in this hand-held adhesive tape dispenser.
So, the handle is constituted of three parts:
As a standard hand-held adhesive tape dispenser, the hand-held handle dispenser 10 of the invention essentially comprises a main frame 12 having a handle 14, an adhesive tape roll 16 provided at a rear side of the main frame, an application roller 18 provided at the front side of the main frame and a cutting blade 20. According to the invention, such dispenser further comprises an insert strip cartridge 22 for storing pre-cut insert strips 24, transport/selection rollers 26 for conveying one by one the pre-cut insert strips from the cartridge to the application roller 18 and a trigger 28 for controlling the transport/selection rollers and initiating the affixing of a first pre-cut insert strip. If the length of the first pre-cut insert strip is too short for the handle wanted by the user, then the user can trigger a second pre-cut insert strip to be dispensed just after the previous, and so on to create a very long strip (strap like). This results in the possibility of having different handle lengths (the length however will be a multiple of pre-cut insert strips only) close and tight to the parcel so as not to be torn off (small loop (hand bag) style). Moreover, it can be noted that this solution is less expensive and easier to print advertising.
Preferably, the insert strips can be a thin strip of paper approximately 45 mm×205 mm. The side of the strip, which adheres to the tape, can be printed with some advertising information. This advertising information could be seen through the tape when this one is transparent or partially transparent. Advantageously, the non-printed side of the strip can be coated with a thin film of plastic of same dimensions measuring approximately 45 mm wide so as to improve adhesion to the transport/selection rollers. Another possibility is to use thin films of plastic measuring approximately 45 mm×205 mm instead of paper strips.
The distribution of the insert strips operates as follows. Firstly, the activation of the trigger 28 turns the transport/selection rollers 26 thus advancing an insert strip 24 towards the adhesive surface of the adhesive tape. More particularly, the transport/selection rollers preselect the undermost insert strip from the insert strip cartridge 22, and advance it against the adhesive surface of the adhesive tape. The action of advancing an insert strip towards the adhesive tape results in adhering the insert strip to the adhesive tape and therefore in creating on the adhesive tape of a zone whereby the adhesive tape is no longer capable of is adhering to the parcel, thus creating a zone free of adhesive to be used as a “handle”. This non-adherent zone also means that the “handle” does not adhere to the user's hand while carrying the parcel.
The user can repeat the process so as to have the insert strips coming one behind the other. This will increase the length of the non-adherent zone thus increasing the “handle” length too. The user can obtain different handle lengths at will.
Indeed, rather than triggering an automatic bringing of the pre-cut insert strip in contact with the adhesive surface of the tape, the overall insert strip cartridge can be brought in contact with the adhesive surface of the tape via a sliding action and a spring mechanism. The dispenser 30 comprises as previously a main frame 12 having a handle 14, an adhesive tape roll 16, an application roller 18, a cutting blade 20 and an insert strip cartridge 22 for storing pre-cut insert strips 24. However, neither transport/selection rollers 26 nor trigger 28 are present in this configuration for affixing of a first pre-cut insert strip.
The overall insert strip cartridge 22 can be slid horizontally relative to the main frame (comprising the rest of the dispenser elements). A pusher button 32 allows the user to slide horizontally the insert strip cartridge and thus bring the pre-cut insert strip into contact with the adhesive surface of the adhesive tape. This action brings only the uppermost pre-cut insert strip 24 against the adhesive surface of the adhesive tape, resulting in immediately adhering an insert strip to the adhesive tape.
During this phase when the user pushes on the pusher button to slide horizontally the insert strip cartridge, a spring 34 is compressed. When the user releases the pusher button, the insert strip cartridge slides back to its initial or is rest position due to the effect of the spring, thus separating the uppermost pre-cut insert strip, which adheres to the tape, from the others remaining in the insert strip cartridge.
In this configuration, the distribution of the insert strips operates as follows. Firstly, the activation of the trigger 28 by the user turns the transport/selection rollers 26 thus advancing the insert strip roll so as to adhere to the adherent surface of the adhesive tape. As the user continues to dispense the tape, the insert strip roll adheres onto the tape and creates a non-adherent zone “handle” equivalent in length to the distance unrolled by the user of the insert strip roll prior to cutting it.
When the adequate length of handle is obtained, the dispensing of insert strip roll needs to be stopped. A further and deliberate action by the user on the trigger 28 forces the presser 46 to rise. This lifts the insert strip roll towards the knife 48, thus resulting in cutting the insert strip roll. Once the insert strip roll is cut, the user can resume affixing the adhesive tape on the parcel to fasten the second side of the handle onto the parcel.
When the user releases the trigger, the trigger automatically returns to its rest position via the spring mechanism 50. During the returning of the trigger to its is rest position, the transport/selection rollers 26 are not rotated and the insert strip roll remains in its actual position. The presser returns to its rest down position via a spring mechanism too for example. Thus, the hand-held handle dispenser system is back in the initial stage and a new handle can be initiated by the user at his will.
In a variant of this second embodiment, the insert strip roll includes perforated separating lines. In this case, the cutting mechanism is replaced by a system enabling the tearing of the roll at the user's will. When the user decides to end the non-adhesive zone of the handle, he activates the blockage of dispensing of the insert strip roll. Once the insert strip roll is blocked, the perforated separating line situated between the blocking point and the point of contact with the adhesive tape will be torn by the pulling force resulting from the tape dispensing action.
Preferably, the distance between the perforated separating lines must be equal or slightly less than the distance between the blocking point of the insert strip roll and the point of contact with the adhesive tape with the insert strip roll. Thus, only one perforated separating line shall be positioned between the blocking point of the insert strip roll and the point of contact with the adhesive tape with the insert strip roll. The tearing of the insert trip shall take place in a controlled manner, resulting in a determined handle length.
Regardless of the embodiment, the operation for dispensing a handle with the hand-held handle dispenser of the invention can be summarized as follows with reference to
Depending on the embodiment, stopping the dispensing and affixing of the insert strip roll is made by tearing the insert strip roll via the presser 46 blocking the insert strip roll or by cutting the insert strip roll via acting on the knife 48.
It is recommended that the non-adhering part of the handle be preceded and terminated by a length of adhesive tape measuring at least 15 cm, and adhering to both opposite sides of the parcel. The non-adhering part of the handle should start on the top edge of the parcel and should reach the opposite edge of the parcel. Furthermore, for better resistance, it is recommended that the adhesive parts of the handle adhere onto the adhesive tape already used for closing the parcel.
Large parcels may require more than one handle. Two handles can be placed on either side of the parcel and perpendicular to the longest edge. This enables the parcel to be carried by one or two persons depending on its size and weight.
It must be noted that the different elements for dispensing the insert strip or insert strip roll can be provided as handle distributor kits for upgrading standard adhesive tape dispensers in the field or for producing brand new combo tape and handle dispensers, and benefiting from the experience curve and economies of scale of current adhesive tape dispenser. Alternatively, the handle distributor can be integrated onto adhesive tape dispenser currently distributed on the market place allowing the following possibilities such as integrating the handle distributor within the production line of adhesive tape dispenser.
