16 Claims.

This invention deals with an improved and serviceable tape dispenser of the type comprising a container having tubular means for supporting a roll of tape and embodying a serrated jaw spaced from the tubular means to permit an unwound free end of the roll of tape to be temporarily secured thereto or severed thereby. One of the objects of the invention resides in the pro-- vision of a container in the form of a hollow cylindrical shell having one closed side integral with an annular rim interrupted by an appreciable gap adapted to be open or shut by the jaw or closure which is pivoted on the lower part of the rim. Another object is realized in the provision of means for removably locking the swingable closure or jaw in its fully open or shut relation with the interrupted rim. More speciiically another object resides in the provision of a cover removably associated with the rim and swingable closure to maintain the roll of tape within the shell. Another important object resides in the provision of a substantially disc shaped cover having a concentrically arranged tubular nipple embodying resilient and flexible but spaced diametrically disposed arms including radially and laterally extending lips adapted to be actuated by the wall of the bore of the tubular means of the shell for automatically shifting or flexing the spaced arms towards each other when urged through the bore by the operator actuating the cover and subsequently when the lips become free of the tubular means, the spaced arms automatically shift outwardly or radially due to resilient retraction of the spaced arms for removably engaging the closed side of the shell to preclude lateral displacement of the cover away from the rim of the shell. Another object is to utilize the cover to removably lock the swingable jaw or closure to the interrupted annular rim. A iurther object is to preclude rotationof the cover relative to the rim pursuant tc locking of the swingable closure by the cover. Another object is to provide a novel sensitive pressure tape dispenser preferably of a suitable plastic and adapted to be conveniently carried in a closed and locked relation in a pocket of the operator and after removal from the pocket, the swingable closure may be readily shifted to its open position by linger pressure on the part of the operator. Ancther salient object is concerned with a demountable tape dispenser wherein both the swingable tape supporting closure or jaw and the locking cover may be readily and completely disconnected from or subsequently assembled with the shell.

Other salient objects and 2 functional structural features and advantages of the invention will appear from the following detailed speciiications considered in the light oi the accompanying drawings wherein:

Fig. 9 is an exploded perspective view of the dispenser.

`Illustrative of the embodiment disclosed, the tape dispenser TD comprises a one piece shell or container S characterized by an annular rim R. integrally merged with the disc shaped annular side wall Ill embodying the concentrically arranged inwardly overhanging tubular portion Il constituting a support for the tubular core C of a roll of pressure sensitive tape TP.

Appreciably interrupting rim R is the cutaway portion or gap CA (Fig. 9) adapted to be opened and closed by the swingable one piece unwound tape supporting member TS which embodies a front arcuate wall l2 substantially complementary to rim R. Speciiically the tape supporting member TS may be considered as a conveniently accessible closure or jaw wherein the lower part of the arcuate front wall i2 is integrally merged with the cylindrical pin or pintle P provided with laterally extending and reduced outer ends i3 and I4.

Extending laterally of rim R at the lower part ofV gap CA is the arcuate bearing B which serves to rotatably support pintle P having its cylindrical reduced end i4 removably receivable in opening l5 of ear E integrally merged with rim R and side wall` I!) of shell S.

Forming a part of closure or jaw TS and extending substantially normal to and rearwardly of its iront arcuate wall I2 is the wing W which is movable against the outside surface of wall I and has arcuate slot I6 removably receiving the outwardly extending guide pin or projection 'Il' merged with and projecting from wall I.

Of interest, it should be observed that the lower part of the arcuate closure wall l2 is slightly cutaway to provide the relief and positioning notch iii (Fig. 9) for removably receiving ear E to permit the lower side face portion I9 of wall I 2 to be arranged flush with the outer surface of wall I0 of shell S when shoulder 23 of pintle P and the alined vertical face 2| of notch I3 meet ear E after reduced portion i4 is located in opening or perforation I5 of ear E.

Towards the upper end of the tape support TS is the ledge L rabbeted as shown and having the toothed face TF slightly below the upper surface 22 which together with the lower face 23 of the upper part of annular rim R form a relatively narrow slot SL (Fig. 7A) to permit the unwound end UE of the roll of tape TP to pass through and into and through throat T defined by the outwardly extending lip or guard LP merged with annular rim R and the rabbeted ledge L of the swingable closure or free end tape support TS, which in Figs. 1 and '7 is shown in a shut relation, that is, with the front arcuate wall I2 across and closing cutaway portion CA and substantially complementary to rim R at which time faces 22 and 23 are just slightly spaced apart (Fig. 7A).

Swingable closure or jaw TS is held shut by post or posterior stop 24 cooperating with the curved end wall 25 of the arcuate slot I6 in wing W which has its lower beveled end or relief cutaway portion 26 spaced from and above ear E to allow tilting of wing W relative to ear E when arranging cylindrical reduced end I4 of pin P in opening or perforation I5 of ear E in assembly of closure TS and shell S.

With reduced end I4 within opening I5, wing W can be tilted outwardly away from wall I0 of shell S and thereafter swung to permit both anterior projection I'I and posterior post or stud 24 to be received within and at the ends of slot I 6 in wing W as shown in Fig. 1, anterior projection I1 cooperating with curved end 26 to limit inward displacement of the swingable tape support or jaw TS at which time also corner CR (Figs. 1 and 9) thereof is arranged within relief notch N and the tape support or closure TS is fully shut and as previously stated held in such position and against accidental outward displacement by the rear post 24 acting as a stop against end 25 of slot I6 while front end 23 of slot IE cooperates with projection I 'I to limit outward displacement of closure or tape support TS when the latter is unlocked from stop 24 and moved to a fully opened position.

Annular rim R has one side closed by wall I0 and the side 30 of the rim opposite to wall I2 is open as shown in Fig. 9 but is adapted to be closed by the disc shaped cover 3| having the circumferential ange F closely but removably tting over annular rim R.

Flange F is interrupted by gap GP (Fig. 4) having upper and

lower faces

32 and 33 closely but removably straddling lip or guard LP and bearing B projecting from rim R, thus serving to prevent rotation of cover 3| relative to the shell S. However before mounting cover 3| on rim R, the free end tape supporting member or swingable closure TS is journalled on the rim R as previously pointed out.

According to the invention cover 3| is a one 4 piece member preferably, as in the case of both shell or container S and the swingable closure TS, of a suitable plastic material, and embodies the annular boss 34 (Figs. 5 and 8) from which extends the annular bushing or nipple 35 integrally merged with the diametrically spaced and resilient and exible arms 36 each having a laterally or radially extending lip or lug 3'I adapted -to snap over and yieldingly engage side I0 of shell S (Fig. 1), thus automatically locking cover 3| against transverse displacement when on the shell at which time core C (Figs. 5 and 7) of the roll of tape TP is rotatable on tubular portion II and is conned between boss 34 of cover 3| and boss 38 of side wall Ill (Fig. 5).

In the assembled relation of the container or shell S, tubular portion I| also closely but removably telescopes over nipple 35 of cover 3|. The swingable closure TS has spaced ribs 40 on the inside surface of wall I2 thereof to resist sticking of loop 39 ofthe unwound part of the tape against this surface. Loop 39 provides desirable and adequate slack to permit easy opening of closure TS from its shut position (Fig. 7).

Brieiy recapitulating, with the tape dispenser TD unassembled as illustrated in Fig. 9, the roll tape TP can be readily positioned on the tubular support II, before or after swingable closure or free end tape support TS is journalled to the shell S. Of course in assembled relation, arcuate wall I2 and its merged wing W straddle side wall ID of the shell if it is taken in consideration that ear E is a part of side wall II. The free end UE may now be grasped and unrolled from the roll of tape and placed against the uninterrupted face 22 and toothed face TF of closure TS, leaving the front margin thereof extending outwardly beyond this toothed face as indicated in Fig. '7, allowing quick access thereto. Closure or jaw TS is now swung shut, forming the loop 39. Thereafter, closure disc 3| is mounted on shell S. This is accomplished by inserting locking lugs 3l' into the bore BR of the tubular tape roll support This can be effected in that after one of the lugs 37 is inserted into this bore, it is utilized to cooperate with the wall of the latter to iiex its resilient arm inwardly, thus permitting the other lug to be received within bore BR. Subsequently cover 3| is moved towards side wall I0 and if necessary rotated relative to rim R until opening or perforation 4I of ear or lobe 42 which is integral with cover 3| lines up with reduced cylindrical portion I3 of the fulcrum pin P at which time lips or lugs 31 snap against the outer surface of side wall I0 (Fig. 1), consequently locking cover 3| to shell S, and against rotation relative to the latter in view of ear 42 interlocking with pin P and

faces

32 and 33 of interrupted ange F straddling lip or guard LP and bearing B.

As previously stated, post 24 holds closure TS against accidental opening. Even in this relation, the protruding margin of the free end UE of the pressure section tape T may be grasped and pulled outwardly to unroll the length of tape desired to be subsequently severed by the teeth defining the toothed face TF. In the majority of instances, it is desirable to have swingable closures TS fully opened during unwinding or dispensing. Hence closure TS is shifted to the position illustrated in Fig. 3 from its closed position shown in Figs. l and 5 wherein posterior corner 43 of wing W extends across or overlaps a part of bore BR of shell S. This is achieved by applying thumb pressure under the curved corner 43, thus slightly ilexing and lifting wing W over post 24 and over the intermediate projection or stop 44 integral with side wall I@ whereby7 the wing W is removably interposed between the outer or front stop or projection i1 and the intermediate stop 44. Stop it serves to prevent accidental rearward shifting of the swingable closure TS when fully opened while projection i1 limits outward displacement of this closure. Stop 4t has the inclined cam face to automatically lift corner 43 to easily clear the front part of stop 44. In addition, projections I1 and 45 may be said to interlock and straddle a part of wing W to hold closure or jaw TS in a set open position.

After a length of tape is withdrawn and severed, the free end of the roll is then stuck against faces 22 and TF of ledge L. Rearwardly directed iinger pressure on the part of the operator against front wall i2 causes closure TS to swing to its shut position and concomitantly its wing W over and beyond the intermediate stop M and over and beyond the posterior stop or projection 2d. This action is possible in that the posterior inclined side E of ing W is rounded and beveled, and there is slight play in the hinged connection defined by caring B and fulcrum pin P and also due to the fact posterior stop 24 is also beveled as shown. With the closure TS shut, wing W has shifted to its fully retracted position as shown in l and 5 in which case posterior stop or projection 2li serves to preclude accidental opening of closure TS.

In the event the roll of tape is used up, and a fresh roll is to be substituted, the dispenser TP may be readily opened by urging lips or lugs 31 towards each other by ringer pressure. This operation correspondingly exes the spaced resilient and flexible arms 36 towards each other, and due to the outward thrust imparted by arms 3c against the wall of bore BR automatically arranging the spaced lugs or lips 3l within bore BR of roll support ii, and also automatically shifting the perforated ear or lobe 42 of cover 3l out of engagement with the reduced end i3 of pin P. The cover is now unlocked from shell S and its spaced arms 35 are withdrawn from support i i by the operator pulling outwardly on cover 3 i. Upon complete withdrawal from tubular support il, these arms 3G automatically retract. Also after such complete withdrawal, cover 3i is completely removed from the shell S. Hence access may be readily had to the interior of the shell and particularly te tubular support il thereof, for removing the exhausted roll of tape and substituting a fresh roll in its place, after which the cover Sil can again be ouiclrlv assembled to disengageably interlock with shell S.

Diverging from and integral with rim R are the spaced hns or legs el adapted to support the dispenser TD on a supporting surface SS, if desired during dispensing operations, although generally the dispenser is preferably held in one hand of the operator in such cases while the other hand is used to unwind the roll at a time when the closure TS is fully opened (Fig. 6).

By the arrangement disclosed, the dispenser when not in use may be desirably carried in a pocket of clothing or positioned on an appropriate supporting surface as SS.

Various changes may be made in the details of construction and arrangement of parts without departing from the scope of the invention or sacrificing any of the advantages thereof inherent therein and in the method hereinbefore set forth.
