Abstract

A device for dispensing adhesive tape directly onto a surface includes a housing comprising a pair of spaced tear-drop shaped panels and a wall joining the peripheral edges thereof. A spool extending between the panels supports a roll of adhesive tape in rotatable fashion, with the free end thereof extending to a slot opening in the apex of the housing. A post extends between the panels medially of the roll and the slot opening. A spring member is secured to the post, one end thereof having a serrated cutting edge and anvil disposed in the slot opening, the other end impinging resiliently on the supply roll to act as a brake thereon.

Claims

1. A device for dispensing a tape web from a supply roll onto a surface, comprising;

a housing including a pair of rigid, tear drop shaped panels disposed in parallel, spaced apart relationship;

spool means extending between said panels for supporting said supply roll in rotatable fashion;

said housing including a side wall joining the peripheral edges of said panels,

a slot opening in said side wall adjacent to the apices of said panels, said tape web extending from said supply roll through said slot opening;

a post extending between said panels and disposed intermediate of said supply roll and said slot opening; and

a leaf spring member secured to said post, one end of said leaf spring member resiliently impinging on said supply roll, the other end extending into said slot opening and resiliently impinging on said tape web.

2. The device of claim 1, wherein said other end of said leaf spring member includes a serrated cutting edge at the distal end thereof.

3. The device of claim 2, wherein said leaf spring member includes an anvil portion for urging said tape web smoothly onto a surface, said anvil portion being integrally formed in said leaf spring member adjacent to said serrated cutting edge.

4. The device of claim 1, wherein said leaf spring member includes a medial concave portion extending partially about and engaging said post.

5. The device of claim 4, wherein said resilient impingement of said leaf spring member on said supply roll and on said tape web are substantially equal and opposite in moment, said post being a pivot for said leaf spring member.

6. The device of claim 2, wherein said slot opening includes a front edge adjacent to said apices, and a rear edge spaced from said front edge and said apices, said other end of said leaf spring member pinching said tape web against said rear edge.

7. The device of claim 6, wherein tension in said tape web applies a counter-moment to said other end of said leaf spring member to urge said other end in flexural movement toward said front edge and relieve said pinching of said tape web.

8. The device of claim 7, wherein said housing is rotatable about said apices to cause said tape web to traverse said cutting edge and be severed.

9. The device of claim 7, wherein release of tension in said tape web relieves said counter-moment in said leaf spring, said other end thereof returning to pinch said tape web against said rear edge of said slot opening.
