6 Claims, 10 Drawing Figures ADHESIVE TAPE DISPENSER This is a division of application Ser. No. 218,930 filed Jan. 19, 1972, now abandoned.

BACKGROUND OF THE INVENTION This invention relates to adhesive tape dispensers.

Adhesive tape dispensers are generally one of two different types. One type is a hand-held dispenser which has to be grasped in one hand while tape is removed with the other hand and the other type is a selfsupporting dispenser which can rest on a table-top and from which tape can be withdrawn with one hand only.

It is an object of this invention to provide a border for a hand-held dispenser which can be used to convert a hand-held dispenser into a self-supporting dispenser and thus obviate the necessity of having two separate dispensers.

SUMMARY According to the present invention, there is provided a self-supporting holder for a hand-held adhesive tape dispenser, which comprises a seat for the dispenser and means for preventing displacement of the dispenser during withdrawal of tape therefrom, the holder being adapted to release the dispenser when desired and being so weighted or being adapted to be so secured that it will remain stationary on a support surface during withdrawal of tape from the dispenser.

With the holder of this invention it is only necessary to have one manually held applicator and a holder. Adhesive tape can be removed as required from the dispenser when located in the holder placed on a table. If, however adhesive tape is required at any other place the applicator can be removed from the holder by a simple manipulation.

According to one embodiment of the invention, the bottom surface of the holder may be covered with an adhesive tape sticky on both sides to secure the holder to a flat surface and a chamber may be provided for holding reserve adhesive tape either in rolled or elonated form.

Whilst in most known dispensers the adhesive tape has to be pulled out by hand, hand-held dispensers with a double function are known. The adhesive tape is either pulled out by hand or is directly applied by moving the dispenser over the surface to be taped. Such dispensers have a manually operated member for changing the direction of the tape, this member being usually in the form of a sliding part. If this member is in its lower position, the adhesive tape being unwound runs lower than the cutting knife, so that a cutting action is avoided. When the member is in its upper position, the adhesive tape runs higher and the tape comes into contact with the knife and is severed thereby.

For use in conjunction with this kind of dispenser, a further embodiment of the invention incorporates a resilient member by the action of which the member for changing the direction of the tape is forced towards the band exit opening when the dispenser is positioned in the holder.

DESCRIPTION OF THE [PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, the holder A which is in the form of a casing adapted to receive a tape dispenser, has a trapezoidal vertical cross-section. Two broad side walls 2 are in the shape of a parallelogram so that the front wall 3 is inclined at an acute angle to the bottom plate 1. On the side opposed to the insertion opening 4, the upper wall 5 is provided with a forwardly inclined recess or opening 6. Two longitudinal ribs 7a, 7b of different lengths are formed on the inside of each side wall 2 and a longitudinal groove 8 open towards the rear is formed therebetween to receive a spring 10 which is E-shaped in plan and which with its outer limbs is in clamping engagement with side walls 2. The central limb 10a of the spring is downwardly bent.

A hand-held dispenser B shown in broken lines is formed so that adhesive tape can be manually withdrawn as well as applied directly. The dispenser B comprises in addition to a rotatably supported adhesive tape roll 11, a knife 12 and a slidable member 13 for changing the direction of the tape, the slidable member carrying a rotatable roller 14 at the end next to the knife 12. When it is not inserted in the holder, adhesive tape can be manually removed in the usual manner from the dispenser B. For directly applying adhesive tape, the dispenser is grasped in one hand and is inverted in respect to the position. shown in the drawing and is passed over the article to be taped, the sliding member 13 being depressed during this movement by the index finger. In this manner the adhesive tape 11a is pressed by the roller 14 against the supporting surface. As soon as the sliding member 13 is released, the adhesive tape lla comes into contact with the knife 12 and is severed thereby.

By inserting the hand-held dispenser B in the holder A, the device is converted into a self-supporting dispenser which can be used on a table. In the longitudinal direction, the front wall 3 forms the necessary abutment whilst the upper wall 5 secures the dispenser vertically in position in relation to the bottom plate 1. Durby the knife 12. For removing a strip of adhesive tape, the adhesive tape 11a is first of all pulled upwardly at a steep angle. By dipping the tape so that it makes a flatter angle, the sliding member 13 is pushed downwardly as a result of the tensile force set up by pulling and is pushed downwardly against the action of the spring limb a so that the desired cutting contact is made between the adhesive tape llla and the cutting edge of the knife 12. The tape is severed and the sliding member 13 is again forced upwardly by the action of the spring limb 10a. By virtue of the rear portion of the dispenser B being freely accessible, the dispenser can easily be removed from the holder A in which it is inserted and can also be inserted therein just as easily.

In an area located above its lower forward corner, holder A is provided with a chamber 15 which houses a length of tape 16a which is adhesive on both sides and which is wound up as a roll 16. The bottom of this corner area is also formed with a slot 17 through which the adhesive tape 16a can be removed. A portion of tape corresponding in length to the bottom plate 1 is withdrawn and pressed against the bottom underside. After that, the protective cover 16b is peeled off and severed in the area of the slot 17. The holder can now be secured by virtue of being self-adhesive on any surface such as a table, cupboard surface, window or the like. When the adhesive action has been lost by repeated removal of the holder, the used-up section of tape is detached from the bottom and a new section is drawn out as above described. The used-up section is torn off.

It is obvious that there may be arranged between the bottom plate 1 and the dispenser B an oblong tape chamber for the reception of adhesive tape which is sticky on both sides. In this event the space for the dispenser B would be separated from said oblong chamber by a partition or lateral ribs.

In the embodiment shown in FIG. 3, the holder is in the form of an upwardly open socket A 1. When sliding in the handheld dispenser B 1 having a member 23 for changing the direction of the tape, small ribs 21 arranged on the broad sides of the dispenser engage in grooves in the socket. By this engagement between ribs and grooves and by virtue of the abutment of dispenser B 1 against the front wall 22 of the socket A l, the desired retention of the dispenser for removal of the adhesive tape is achieved. The socket A 1 can be secured on any desired surface by means of an adhesive tape which is sticky on both sides. The socket can also be secured in position by screw means or it may be of sufficient weight to resist movement.

- In the embodiment shown in FIG. 4, the holder is in the form of a plate or rail A 2 and is provided with a springy snap fastening means. This fastening means consist of two springy ears 31 laterally formed on the rail. The ears are formed with holes 32 or recessed portions adapted to receive projections 33 arranged in suitable positions on the hand-held dispenser B 2. An integrally formed resilient tongue 34 cooperates with a member 35 for changing the direction of the tape in the same manner as has been described in connection with the embodiment of FIGS. 1 and 2. The interengaging means 31, 32 and 33 prevent horizontal movement of the dispenser and also secure it in position against vertical movement.

An adhesive tape which is sticky on both sides and which is used for securing the rail 30 on any flat surface is designated by reference 36.

In the embodiment of FIGS. 5 and 6, a holder A3 is in the form of a rail 40 having a U-shaped cross section. The two short limbs of the U form two grooves 42 on the sides facing each other. A hand-held dispenser B 3 shown in broken lines has two ribs 43 formed on its two broad side walls which engage in the grooves 42. The dispenser B3 is simply secured by sliding it on rail 40.

It would be possible to make the rail U-shaped only in that area in which the ribs 43 are located on the dispenser B3. An equivalent arrangement for holding the dispenser and holder together comprises grooves on the dispenser and corresponding ribs or other projections on the rail 40.

At its forward end, the rail 40 is provided with a bridge piece 44 which is springy at its upper portion. This cooperates in the manner already described with a member 45 on the applicator B3 for changing the direction of the tape. The end of the bridge piece 44 can also be formed by a metal spring.

For its protection and for aesthetic reasons, the bridge piece 44, which in addition to its function as spring also serves as an abutment stop for the dispenser B3, may be surrounded by wall portions 46 and 47. By omitting the front wall 47, the moulding is simplified and the rail 40 can be forwardly extended up to the end of the holder.

As can be seen in FIG. 5, the bridge piece 44 can also be used for holding the dispenser B3 in locked engagement. For this purpose, the rear corner portion of the rail is formed with a hook which is springy towards front or rear. The hooked-shaped extension 49 of the rail is shown in dotted lines and engages a lug 50 on the dispenser. On the opposite end, the dispenser is formed with a rounded protrusion 51 which is located in a corresponding recess 52 in the bridge piece 44. The dispenser is held first in an inclined position so that the lug 50 and the hook-shaped extension come into engagement. It is then turned down until the protrusion 51 is locked in position by virtue of the springyness of the bridge piece 44 or the hook-shaped part 49. The elasticity required for this connection can also be obtained by forming the recess 52 in the bridge piece 44 for the reception of protrusion 51 in a springy piece held in a U-shaped slot in the bridge piece 44.

FIG. 7 shows in cross-section a holder A4 which is in the form of a rail 60. The rail 60 is provided with a keyhole slot61 which can be seen in the plan view of the rail shown in FIG. 8. A dispenser B4 is formed on its underside with an undercut projection 62 which can be readily engaged in the keyhole slot 61. By moving the dispenser lengthwise, the projection 62 is moved into the narrower part of the keyhole slot and the parts are in this way securely held in position. The end 64 of the keyhole slot acts as abutment.

The holder A5 shown in FIGS. 9 and 10 serves to hold a hand-held dispenser B5 which is provided with a handle portion 71. The upper casing wall 72 is forwardly inclined from the opening 73 for sliding in the handle and at some distance from this opening has a recess 74. The dispenser B5 with its handle in an inclined position is inserted into the opening 73 from above and is then rotated clockwise and brought into an horizontal position. In this way the protrusion 75 on the handle is engaged in the recess 74 and secures the dispenser in position. In order that the dispenser is prevented from being swung upwardly, a sliding member 77 located on the inside of the casing side wall 76 is pulled out so that its forward end 78 projects over a projection 79 on the applicator. For limiting the extent to which the handle can be inserted, a projection 80 on the underside of the handle engages in a recess 81 in the casing bottom 82. An adhesive tape roll 85 is located in a chamber 84 formed between the free end of the handle and the front inclined wall 83 of the holder A5. An adhesive tape 86 which is sticky on both sides can be pulled out through a slit 87 and can be stuck against the outside of the casing bottom 82. The special handling of the adhesive tape has already been described above.

The holder A5 can, for example, be securei to the edge of a work table so that the adhesive tape roll 89 is located outside the table surface. The holder AS can also be screwed onto a surface and for this purpose the bottom of the casing 82 is provided with holes 96.

Normally with this dispenser the adhesive tape is applied directly. For this purpose the handle of the applicator when not been mounted in the holder is seized and the dispenser is moved over the surface to be taped. The adhesive tape 92 is forced against the surface by rollers 90 and 91. The roller 91 forms the lower end of a member 93 used for changing the direction of the tape and is capable of being moved into two positions. During the direction application of the adhesive tape it is locked in the position shown so that the path of the tape is located lower than a knife 94. When the tape is to be severed, the lever 95 is operated to unlock a locking mechanism (not shown) of member 93 so that the latter is displaced towards the roll 89 by virtue of the tension present in the tape 92. In this way the adhesive tape comes into contact with knife 94 and is cut thereby. As soon as lever 95 is released, a spring (not shown) forces the member 93 again into the position shown in the drawing. When secured in the holder A5, adhesive tape can be manually removed without difficulty from the dispenser B5. It is only necessary to seize the end of the adhesive tape 92 and pull out the desired length and then operate the lever 95.

It has also been determined that a small package can be taped much better when the dispenser B5 is fixed in its holder. The package is seized with both hands and placed on both rollers 90, 91 whereby contact is made with the end of the adhesive tape 92. The package is then slid over the rollers until the first side has been taped and is then turned through 90 and taped on the second side in the same manner until the tape runs completely round the package. The adhesive tape is then severed by actuating the lever 95. This manner of working is more efficient than manipulating with one hand a dispenser which is not held in a holder and holding the package in the other hand and having to turn it around.

Naturally the connection between the handle of the applicator and the holder can be realised in any other manner or by means different to those shown.
