BAG HOLDER 2 Sheets-Sheet 2 Filed Jan. 8, 1962 730 W 1h. 9 FIGS? INVENTOR. JACK W. HOBBS ATTORNEYS United States Patent 3,091,422 BAG HQLDER Jack W. Hobbs, 3371 Waterside Drive, Akron 19, Gino Filed Jan. 8, 1962, Ser. No. 164316 Ciaims. (Cl. 243-101) The present invention relates to an apparatus or device for holding disposable litter bags. A device or bag holder constructed according to the invention may be semipermanently attached to or mounted on a surface such as a cabinet door, an automobile dashboard, a wall surface, etc., presenting a disposable bag for easy filling.
There are disclosed and shown herein two forms of a bag holder constructed according to the invention.
In the drawings:
FIG. 1 shows a preferred form of bag holder, mounted on a Wall surface;
FIG. 2 is a perspective view of the device of FIG. 1 in the open or bag removal position;
FIG. 3 is an enlarged cross-section taken substantially as indicated on line 33 of FIG. 1;
FIG. 4 is a top view of the device of FIG. 1 in the closed or bag holding condition;
FIG. 5 is a side view, of the device of FIG. 1, particularly intended to show removal of the release paper protecting a pressure sensitive layer on the base of a device prior to mounting on a wall surface, as in FIG. 1.
FIG. 6 is an end view of the device, of FIG. 1, particularly intended to show an inherent concavity built into the base webs of the device, to facilitate mounting;
FIG. 7 is a perspective view of an alternative form of bag holder in the open position;
FIG. 8 is a top view of the device of FIG. 7 in the closed condition;
FIG. 9 is a side view of the device of FIG. 1, particularly intended to show removal of the backing material protecting the contact-adhesive layer on the base of a device; and
FIG. 10 is an end view of the device of FIG. 7.
The preferred form of device or bag holder is indicated generally by the numeral 10. A device 10 has an elongated rib 12 extending laterally away from the medial portion of a generally rectangular base member 14. The rib 12 is frictionally engaged by an over-fitting clasp bar 15 hingedly attached as by a rivet 16 to one end of the rib. The rib 12 preferably has tapered sides converging away from the base 14 at a slight angle, for example, 1, for better frictional engagement with correspondingly tapered sides of the clasp bar 15.
The rib 12 and base 14 are preferably fabricated as an integral or one-piece T-shaped extrusion of a polyvinyl homopolymer of high molecular weight, suitably compounded in what is usually referred to as a type I formulation, and then out to the desired length. The clasp bar 15 is preferably die stamped or formed from an aluminum alloy and has a rounded point 17 for piercing of the litter bag, as shown in FIG. 1. To provide the optimum frictional engagement between the plastic of the rib and the metal of the clasp bar, either side of the rib 12 may be provided with a series of longitudinally extending halfround beads 18.
Referring to FIG. 1, a device 10 is mounted on a suitable surface such as a cabinet wall 20 to hold a refuse, waste or litter bag 21 in a ready-to-use condition. The device 10 may be attached to the surface 20 by several screws or other mechanical fastening means. However, as an item of manufacture for commercial sale, it is preferred that the base 14 of the bag holder be coated with a double-faced adhesive layer 24, protected until use by a release paper 25. Any properly formulated pressure- 3,091,422 Patented. May 28, 1963 "ice sensitive adhesive, resistant to conventional solvents and household cleaning agents, may be used to form the layer 24. By way of example, the adhesive comprising layer 24 could have a butadiene-styrene rubber base tackified with rosin derivaties or coumarone resins, with filler and antioxidants, and preferably partially vulcanized to establish high internal strength and reduce cold flow.
Referring to FIG. 6, the lateral web portions 26 of the base may be finned or tapered and moderately curved away from the rib 12 to provide a slight curvature or concavity for the base 14 and adhesive layer 24. It has been found that adherence of the device 10 to metal surfaces, such as an automobile dashboard, will be improved by the inherent tension or bias provided by the concave base and adhesive layer indicated at 27.
Referring to FIGS. 710, an alternative form of device or bag holder is indicated generally by the numeral 30. The device 39 is generally of more rugged construction than the device 10 and could be used in commercial estabishments such as restaurants or cafeterias. The device 30 has an elongated rib 32 extending laterally from one side of a generally rectangular base member 34. The rib 3 2 is frictionally engaged by an overfitting clasp bar 35 hingedly attached as by a rivet 16 to one end of the rib.
The device 30 may be attached to a mounting surface by several screws or other mechanical fastening means. Or, the base 34 may be coated with an adhesive layer 24 (as described above), protected until use by a release paper 25.
What is claimed is:
l. A device for holding bags, comprising, a generally rectangular base, an elongated rib extending laterally from said base, and a clasp bar hingedly attached to one end of said rib and overfitting said rib in frictional engagement therewith.
2. A device for holding bags, comprising a generally rectangular base, an elongated rib extending laterally away from the medial portion of said base, a series of longitudinally extending half-round beads on either side of said rib, and a clasp bar hingedly attached to one end of said rib and overfitting said rib in frictional engagement with said rib heads.
3. A device for holding bags, comprising a generally rectangular base, an elongated rib extending laterally from said base and having tapered sides converging away from said base, and a clasp bar hingedly attached to one end of said rib and overfitting said rib in frictional engagement with said tapered rib sides.
4. A bag holder for attachment to a mounting surface, comprising, a generally rectangular base, a pressure sensitive adhesive layer on said base for adherence to said surface, an elongated rib extending laterially from said base and said adhesive layer, and a clasp bar hingedly attached to one end of said rib and overfitting said rib in frictional engagement therewith.
5. A device for holding bags, comprising, an extruded rigid vinyl T-shaped member having a base and elongated rib, said base having finned webs slightly curved away from said rib, said rib having tapered sides converging away from said base, said rib sides each having a series of longitudinally extending half-round beads, and a clasp bar hingedly attached to one end of said rib and overigttirdig said rib in frictional engagement with said rib side ea s.
