2 Claims. 1

This invention relates to improvements in dis- 1 pensers for label strips wherein labels equipped with pressure sensitive adhesive are mounted on backing tapes. It may be regarded as an improvement over the disclosures made in my copending application, Serial No. 349,892, issued as United States Letters Patents 2,373,092, on April 10, 1945, filed August 2, 1940, and the disclosures made in United States Letters Patents Nos. 2,276,- 296 and 2,276,297, issued March 17, 1942, to C. A. Flood.

It is old in the art to which this invention relates to dispense labels equipped with pressure sensitive adhesive and attached to backing tapes by drawing the backing tape over a relatively sharp peeling edge that effectively separates the backing tape from the label by a peeling action. Heretofore, dispensers of various tapes have been provided employing this principle such as are illustrated in the above-numbered patents and application. An objection to the dispensers h'eretofore provided resides in the fact that their constructions are such that the tape must be threaded through structures adjacent the peeling edge that will cause the backing tape to be drawn rather sharply around the peeling edge to efiect separation of the backing from th labels. Although s'uch threading may be readily performed by the designers of these devices and by mechanics skilled in the art, dispensers of this character are usually supplied to and are used by persons possessing little mechanical ability and who fall in the category of unskilled labor.

An object of the present invention is to provide an improved dispenser which is so constructed that a supply roll of backing tape having the pressure sensitive labels mounted there- On can be deposited in a suitable receptacle or other holder and the free end of the tape mere-' 1y drawn adjacent the peeling edge. Thereafter, a combined drag-applying means and bridge are moved relatively to the peeling edge and are caused to assume a proper relationship with respect to the peeling edge so that the backing tape will be effectively. guided and dragged thereby to cause a proper peeling action to take place and the labels to be consecutively deposited on the bridge from which they may be readily removed. By means of the improved construction which is highly simplified threadingof the backing tape through one or more thin passages is eliminated. The user of the device need merely deposit the supply roll in the dispenser and on closing the dispenser the backing tape will be automatically caused to assume a threaded posi- 2 tion with relation to the peeling edge. With this type of construction a user possessing -no mechanical ability can readily replenish the supply roll from time to time as occasion may require and will cause it to assume a position wh'erein the backing tape may be properly drawn about v the peeling edge and the labels separated therefrom and deposited on the bridge.

Another object of the invention is to provide a dispenser which is in the form of an openable receptacle adapted to receive the supply roll and presenting on one of its walls a peeling edge over which the end of the backing tape may be drawn and to'provide a closure for the receptacle which, when moved to closed position, provides and positions a guiding means or drag that will hold the label strip adjacent one side of the peeling edge-providing means as it appreaches, the peeling edge and also a bridge which is caused to assume a position closely adjacent the other side of the peeling edge-providing means, the bridge being so positioned that the labels that are peeled from the backing tape will be deposited thereon and will be kept from following the backing tape around the peeling edge and reattaching themselves to the backing tape.

With the'foregoing and other objects in view,

which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings illustrating only preferred embodiments of the invention, wherein:

Figure 1 is a sectional view through one form of dispenser embodying the present invention;

Fig. 2 is a transverse section taken substantially upon the line 2-2 upon Fig. 1;

Fig. 3. is a. vertical section similar to-Fig. 1, but illustrating the dispenser in open position;

Fig. 4 is an enlarged sectional view of a portion of the dispenser shown in Figs. 1 to 3, inclusive, and illustrating the manner in which the labels are detached from their backing tape and are deposited upon the bridge;

Fig. 5 is a sectional view of an alternative form of construction embodying the present invention;

and

Fig. 6 is a partial view in section illustrating still another alternative form embodying the present invention.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the dispenser illustrated in Figs. 1 to 4, inclusive, consists of a suitable body or base I II which may be formed of any suita backing tape I! on which are mounted paper labels IS. The paper labels are equipped with a pressure sensitive adhesive indicated at l9, although other adhesives that are normally tacky maybe employed. The backing may be formed of any suitable flexible material, such as glassine,-

Holland cloth, Cellophane, Pliofilm or the like.

In drawing the tape or backing strip II around the relatively sharp edge 14 so that the backing tape is nearly reversed upon itself the labels l8 will be effectively separated or peeled therefrom. as indicated by dotted lines on Fig. 4. A cover 20 is provided which is preferably somewhat semicylindrical in form having spaced side walls 2| and 22 mounted for rotation on the side walls II and I2 such as by rivets or the equivalent indicated at 23. These rivets or pivots are so located with respect to the cavity II that the cover may swing about a center that is coaxial with the center of curvature of the recess I l. Preferably. the side walls 2| and 22 engage the side walls 12 and I3 with sufiicient frictional engagement to maintain the cover in closed position when' once moved to this position. In lieu thereof, any suitable detent may be employed for holding the cover in closed position once that it has assumed the same. A portion of the cover indicated at 24 projects or extends inwardly beneath the peeling edge-providing structure 25 so as to be in close proximity thereto, but affording a suitable passage through which the label strip may extend up to peeling edge. This portion and structure 25 serve to guide the label strip as it approaches the peeling edge and to impose a frictional drag on the label strip so that as the free end of the backing tape I! is drawn from the peeling edge, as indicated at 26, the strip will pull smoothly and the backing will effectively peel itself from the paper labels.

On the sides'of the cover there are a pair of arms 21 which are connected by a bridge 28 that overlies the peeling edge-providing means in close proximity to the peeling edge 14. This bridge provides a temporary support against which the labels may be consecutively swung. As the portion 26 of the backing is drawn over the peeling edge I4 in the course of the peeling action, the labels are first projected beyond the peeling edge into a position somewhat as indicated by the dotted lines 29 on Fig. 4. As the peeling action approaches completion on any label the label will tend to swing upwardly into a position, such as indicated at 30, and as'the trailing edge of each label reaches the peeling edge I 4 the labels will tend to swing about the peeling edge l4 as a center and tend to follow the peeled backing. The intervening bridge prevents such following movement as the labels are swung against it they are caused'to temporarily adhere thereto by the exposed pressure sensitive adhesive l9 that comes in contact with the bridge. A substantial portion of each label however projects upwardly above the bridge and may be readily grasped to detach the label from the bridge and applied to the article that is to be labelled. In this manner, by merely pulling on the portion 26 of the backin the label will be caused to be consecutively peeled or separated from the backing and deposited on the bridge. When the supply roll l has become exhausted the device can be readily opened bymerely turning the cover on its pivot 23, thus moving portion 24 and the bridge 28 to a position remote from the peeling edge l4. A new supply roll .may be dropped into the receptacle and the free end of the supply roll drawn over the peeling edge l4. Thereafter, the cover may be returned to'closed position which automatically returns the portion 24 and the bridge 28 to proper position with relation to the peeling edge toimpose the desired dragon the strip of labels as it approaches the peeling edge and to position the bridge 28 above the peeling edge. The arms 21 may be formed to engage the extreme ends of the peeling edge [4 .to limit closing movement of the cover.

In Fig. 5, a similar but alternative construction is disclosed consisting of a suitable body or receptacle 32 having a cover 33 rotable upon pivots 34.

This cover may have a spring 35 secured to its interior adapted to assume a position beneath the peeling edge-providing structure 38. This spring is designed to gently press the label strip 31 supplied from the supply roll 38 against the underside of the peeling edge-providing means as it approaches the peeling edge 39 to impose the desirable frictional drag. The cover also carries a pair of arms 40 which support a bridge 4| above and adjacent the peeling edge. This form of construction functions substantially the same as that previously described, with the exception that the cover by means of spring 35 imposes a resilient or yieldable pressure on the label strip.

The invention is not restricted in its embodiments to a receptacle having a rotary cover. In Fig. 6, an additional form of construction is disclosed wherein there is a receptacle 42 designed to receive a supply roll of labels and this receptacle has a hinged cover 43 which may carry a yieldable spring 44 which presses the label strip 45 against a wall of the receptacle 42 adjacent the peeling edge 46 provided thereon.

.The cover 43 has an opening 41 which exposes the peeling 'edge and carries arms 48 attached to the side edges of the cover 43 as shown which support the bridge 49 above the peeling edge. In this construction, whenever the supply roll becomes exhausted it is merely necessary to move the cover 43 to open position, deposit a supply roll in the receptacle 42, draw the free end of the label strip around the peeling edge 46 and close the cover. Application of the cover supplies the desired frictional drag on the label strip as it approaches the peeling edge and positions the bridge 49 adjacent the peeling edge so as toreceive the peeled labels and prevent their following the peeled backing around the peeling edge.

From the foregoing it i obvious that by means of my present invention, and this is embodied in .all forms disclosed herein, that it is only necessary to move the movable wall portion of-the container to a position uncovering the cavity, when it is desired to refill the same. This movable wall portion in Figs. 1 to 4, inclusive, is the I .5 that the same is led properly to the peeling edge and held in close proximity thereto against the peripheral surface of thecavity. At the same time the bridge member will be positioned over the tape at approximately the peeling edge so as to guide the tape over the outer surface of the fixed wall of the container. The bridge member is positioned to present a projecting surface at an angle to said outer surface to receive the labels as they are stripped or peeled from the tape.

Various changes may be made in the details of construction without departing fromv the spirit 7 and scope of the invention as defined by the appended claims.

I claim:

1. A dispenser of the character described comprising a container having a fixed encompassing wall partially circumscribing a cavity -to receive a roll of tape, which tape has separate but contiguous labels adhesively attached to the inner face thereof, a freely movablewall forming a part of the container and having an encompassing portion complemental to the fixed wall and capable'of being positioned relative to the same to complete the circumscribing of the cavity or uncover the same, one transverse edge of the fixed encompassing wall constituting a peeling edge whereby the tape may be led from the roll with its outer surface contacting the inner surface of the fixed wall and around said edge and over the outer surface of the fixed wall in a reverse direction, the movable encompassing wall having a portion to underlie at a spaced distance the fixed wall at the peeling edge 50 as to engage the inner surface of the tape and guide the same to the peeling edge when the movable wall is in the cavity enclosing position, and a transverse member fixed on the movable wall to overlie the peeling edge to engage the tape as it is led over the peeling edge and guide the same over the outer surface of the fixed wall when the movable wall is in the cavity enclos. ing position, said transverse member having a surface extending outwardly and substantially perpendicularly to the peeling edge in substantial alignment therewith to receive the labels a they are peeled from the tape.
