June 17,1958 R. GUYER WAXED PAPER HOLDER Filed May 18, 1955 INVENT OR United States Patent WAXED PAPER HOLDER Reynolds Guyer, White Bear, Minn., assignor to Waldorf Paper Products Company, St. Paul, Minn, a corporation of Minnesota Application May 18, 1955, Serial No. 509,145
6 Claims. (Cl. 242-555) This invention relates to a simple and effective holder for waxed paper or a similar product mounted upon a hollow cylinder core.
Waxed paper is usually rolled upon a hollow cylindrical core which is then placed within a rectangular carton having a foldably connected top. By swinging the top of the carton open, a portion of the paper may be withdrawn from the carton. The paper may be torn off at the proper length by suitable means such as by a cutting edge secured to the edge of the carton over which the sheet is drawn or by use of a cutting edge on the carton cover.
While such structures are widely and successively used, they have certain disadvantages. In the first place, it is necessary to open the cover of the carton before the contents may be unrolled, Secondly, it is some times difiicult to hold the roll within the carton from rotation while tearing the paper due to the rectangular formation of the carton. Furthermore, the usual carton adds materially to the cost of the product.
An object of the present invention resides in the provision of a support for waxed paper or the like which is not possessed of the difficulty mentioned. The support comprises merely a rectangular frame having an open top and bottom and supporting the roll of wax paper between its ends. As a result, the paper is readily accessible for grasping and the end of the paper may be grasped and withdrawn and cut off at any suitable point.
A feature of the present invention resides in the fact that no difiiculty is experienced in holding the roll stationary during the paper tearing process. As the carton is not possessed with top or bottom panels, it is possible for the side wall panels to flex in if necessary to engage the roll. Furthermore, a flap is provided on the upper edge of the carton and a corresponding finger notch is cut in the lower edge of the same wall. By grasping the carton between the thumb and fingers, the fingers may engage the bottom of the roll while the flap may be pressed against the top of the roll to firmly hold the roll from rotation during the tearing operation.
A feature of the present invention resides in the provision of simple means for supporting the roll of paper. Spaced slots are provided in the ends of the carton and generally U'shaped strips of paperboard may be forced through these slots and into the roll of paper to rotatably support the same. As a result, the roll will rotate readily and the wei ht of the roll will not at all times be upon the surface of the roll. The means rotatably supporting the roll may also act to lock the carton closed, if desired. An added feature of the present invention resides in the low cost of the structure. The carton comprises merely an elongated strip of paperboard folded into rectangular relation. The flap which is provided along the upper edge of the carton may be cut from the lower edge of the next adjoining carton so as to economize on the amount of paperboard used. The
2,839,255 Patented June 17, 1958 ice means for supporting the tape roll are small and can be made at low cost. While a cutting edge may be applied to the carton if desired, such an edge is not necessary as the paper folds effectively over the edge of the carton and may be accurately torn along this edge.
These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.
In the drawings forming a part of the specification:
Figure 1 is a perspective view of the carton in readiness for use.
Figure 2 is a cross sectional view through the assembled structure.
Figure 3 is a diagrammatical View of the carton in blank form.
Figure 4 is a diagrammatical view of one of the roll supporting elements. 7
In order to understand the construction of the apparatus, attention is first directed to Figure 3 of the drawings. This figure shows the blank of the carton which comprises an elongated strip of paperboard which includes an end panel 10, a side wall panel 11 and end Wall panel 12, a side wall panel 13 and an end wall panel 14. These panels are connected along parallel fold lines 15, 16, 17 and 19.
In the assembled form of the carton, the two end panels 10 and 14 are folded into superimposed relation to form a generally rectangular sleeve. In order to hold the sleeve closed, the roll support 20, illustrated in Figure 4, is provided.
The roll support 20 includes a central portion 21 which is foldably connected to tabs 24 and 25 along parallel fold lines 22 and 23. These tabs are preferably provided with tapered ends 26 and 27 for simplifying the insertion of the tabs into the roll. A pair of notches 29 are provided at opposite ends of the fold line 22 and similar notches 30 are provided at opposite ends of the fold line 23. These notches are designed for locking the roll supports in assembled position in a manner which will be later described.
The carton wall 13 is provided with an elongated flap 31 foldably connected thereto along a fold line 32. The flap may be folded against the roll to assist in holding the roll from rotation during the tearing operation. A finger accommodating notch 33 is provided in the edge of the panel 13 opposite that to which the flap 31 is attached. In actual construction the sheet of paperboard is cut with the flap 31 of one carton extending into the notch 33 of the next adjoining carton so as to conserve paperboard. The notch 33 permits the fingers to engage the undersurface of the roll while the flap 31 is pressed against the upper surface thereof. The panel 18 is provided with an elongated slot 34 which is parallel to the fold line 15 and spaced therefrom. The extremity of the panel 19 is notched as indicated at 35. The other end panel 14 is similarly provided with an elongated slot 36 parallel to the fold line 19 and the extremity of the panel is notched as shown at 37.
The other end panel 12. is provided with spaced elongated slots 39. These slots are usually parallel to the fold lines 16 and 17.
The carton is designed to accommodate a roll of waxed paper or the like which is mounted upon a hollow cylindrical core 40 usually of paperboard. The waxed paper 41 is wrapped spirally about the core 40 in the usual manner.
If desired, a strip 42 having a cutting edge 43 may be riveted or otherwise attached to an edge of the carton which in the form illustrated in Figure 3 would comprise the upper edge of the panel 11. The carton is assembled in the following manner. A roll support 20 3 is folded so that the tabs 24 and 25 thereof are in parallel relation. These parallel tabs are inserted through the slots 39 of the end panel 12. By holding the roll of waxed paper 41 against the inner surface of the panel 12, the tabs 24 and 25 may be inserted into the cor-e40 to rotatably support one end of the same. The side walls 11 and 13 are folded into right angular relation with the panel 12 and the end panels and 14 are folded at right angles to the side walls to which they are attached. These panels 10 and 14 are overlapped so that the slot 34 of the panel 10 coincides with the notch 37 of the panel 14 and the slot 36 of the panel 14 coincides with the notch 35 of panel 10. The roll support is then inserted, the tabs 24 and 25 thereof extending into the hollow core 40 and rotatably supporting the same.
The tabs 24 and 25 are equal in length to, or slightly greater in length than the slots into which they extend. Therefore, when they are fully extended into the slots, the notches 29 and 30 engage in the slots and the width of the tabs helps to resist the removal of the tabs from the slots. Thus the carton remains assembled and the waxed paper roll remains rotatably supported.
In accordance with the patent statutes, I have described 7 the principles of construction and operation of my the supported roll.
