COVER LOCK OR SHRDUD 'FOR BOOK MATCH FOLDERS I Filed June 10, 1966 3 Sheets-Sheet 5 Theodore wu/ BY inn/W35 INVENTOR United States Patent Oflfice 3,373,866 Patented Mar. 19, 1968 3,373,866 7 COVER LOCK R SHROUD FOR BOOK MATCH FOLDERS Theodore Will, Syosset, N.Y., assignor to Fund Del Inc., Syosset, N.Y., a corporation of New York Filed June 10, 1966, Ser. No. 556,687 Claims. (Cl. 206-29) This invention concerns an improved cover lock or shroud for a matchbook and particularly concerns improvements upon the cover locks of the type shown and described in my prior United States Patent No. 2,996,- 174.

Cover locks heretofore known for matchbooks or the like have had a number of deficiencies which precluded their general use. They have been fragile in construction so that they tore easily. They were difficult to manipulate for removing and inserting matchbooks. They did not cover the matchbooks so that the striking panels and matches themselves were exposed to moisture. They were notadapted to be manufactured by mass production methods so that they could be manufactured at low cost. They could not be shipped and stored in interconnected, flattened condition to be set up later for insertion of matchbooks. They were not reusable for different make matchbooks because of the varied width of the top narrow cover panels of these matchbooks and because they fell apart by the time one book of watches was used up. They did not hold the Wedge-shaped matchbooks securely enough so that the matchbooks slipped out of the cover locks, or could not even be inserted because of the narrow top open width of the cover locks.

The present invention is directed at overcoming the above difficulties and disadvantages of prior cover locks for matchbooks, and has as a principal object provision of a durable reusable cover lock for a matchbook. The cover lockcan be made of flexible sheet material such as metal, plastic, fiberboard, cardboard, plastic and the like or of molded plastic. The cover lock is tubular in form and wedge shaped in construction, open at the topand open at the bottom. It substantially covers a matchbook for its entire length on front, back and sides. It has a reinforced back for greater strength. Corners of the cover lock are slit to facilitate insertion and removal of the matchbook and to define flexible, expandable springy flaps which securely engage the front, back and sides of the matchbook by compressing for a pressurized grip upon the matchbook and to compensate for any varying thicknesses of the top narrow cover panel of the matchbooks. One panel has a thumb notch to facilitate dislodging the matchbook gripped in the cover lock.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.

Referring first to FIGS. 1-6, there is shown a cover lock 10 embodying the invention. This device is made of a relatively thin flexible sheet of metal, plastic, laminated paper or metal foil, cardboard, fiberboard or other suitable material. The cover lock 10 has a rectangular back panel P1 joined to a narrow tapered side panel P2 by a vertical fold line F1. Fold line F1 terminates a short distance from the upper horizontal edge E1 of panel P1 to define a first short slit S1. The lower edge E2 of panel P2 is narrower than the upper edge E3 of panel P2. Joined to side panel P2 by a vertical fold line F2 is rectangular front panel P3. The lower horizontal edge E4 of panel P3 is equal in length to the upper horizontal edge E5. Fold line F2 terminates short of the upper edges of panels P2 and P3 to define a short slit S2, these slits forming flexible, expandable and springy relief portions at the top of each panel.

Joined to front panel P3 by a vertical fold line F3 is a narrow tapered panel P4 defining the opposite side of the cover lock. Fold line F3 terminates short of the upper edges E5 and E6 of panels P3, P4 to define a short slit S3. The bottom edge E7 of panel P4 is narrower than its upper edge E6. Joined to the panel P4 by a vertical fold line F4 is an inner back panel P5. Panel P5 has a cut off bottom corner C1. The fold line F4 terminates short of the upper edges E6 and E8 of panels P4, P5 to define a short slit S4. These slits S1, S2, S3 and S4 form flexible, expandable and springy relief portions at the top of each panel that permit the insertion of varied size match packages and will securely grip and lock the matchbooks into the cover lock. The outer or rear side 22 of panel P5 abuts the inner or forward side 24 of panel P1. 'An adhesive layer 25 between the two panels P1 and P5 secures the two panels together. Panel P5 is narrower than panel P1, but is sufficiently wide to effect a secure seal to panel P1 and to stiffen a section of this panel at the rear of the cover lock 10. An arcuate notch 26 is formed in the bottom edge E1 of panel P1. The cutoff corner C1 of panel P5 is located just above one end of this notch.

The setup, assembled cover lock 10 is tubular in form, open at the top and open at the bottom with closed front and back walls, and with closed opposite side walls. The cover lock is rectangular in cross section as shown in FIG. 3. The cover lock is wedge shaped and defines a wedge shaped open ended compartment 30. The upper open end of the compartment is equal in horizontal width to the lower open end of the compartment, taken transversely 3 across the cover lock from between side panels P2 and P4. The compartment 30 is wider at the open top than at the open bottom. The panel P projects by its thickness into compartment 30 for its full length and width to create a double thickness with back panel P1.

The slits S1-S4 define narrow flexible expandable springy flap-like portions FL1FL5 at the upper ends of panels Pl-PS. The overlapped flap-like portions FLl and FLS at the back of the cover lock have less flexibility due to their overlapped condition and double thickness to further assist in locking the matchbook in the cover lock.

Due to the tapered or Wedge-shaped construction of the cover lock 10, the wedge shaped closed matchbook 40 Will fit snugly into compartment 30. The cover lock has a length substantially equal to that of the closed matchbook to be inserted therein. After insertion the top cover panel 47 of the matchbook 40 is exposed at the top open end of the cover lock and the bottom fold of the matchbook is exposed at the bottom open end of the cover lock. Thus the striking panel 41 of the matchbook is covered and protected at the front of the cover lock, or at the back if the matchbook is reversed in position, or if the striking coating 41 is located at the back of the match book. The side panels P2 and P4 substantially close the open sides of the matchbook and fully protect the otherwise exposed matches 44. The match layers 44 are held in the match folder panels by a staple fastener 45 in the usual manner providing the bottom fold of the matchbook 40.

When the matchbook is fully inserted into the cover lock as shown in FIG. 5, the flexible, expandable, springy flap-like portions FLl-FLS press against the front and back panels and the side edges of the matchbook to provide a pressurized grip upon the same to frictionally hold it in place in the cover lock. In addition, the inside panel P5 lies within the compartment and presses against the back panel 46 of the matchbook while the front panel P3 of the cover lock presses against the front panels 41 and 48 of the matchbook. The inside panel P5 adhered to back panel P1 provides a doubly stiffening thickness and narrowing compartment 30 to give added pressure against the matchbook. Narrow top cover panel 47 of the matchbook itself covers the assembly on top. The width of the top open end of the cover lock is slightly narrower than the top cover panel 47 of the book match folder. This will allow the cover lock to accommodate varying size matchbook folders by expanding the top flexible expandable springy flap-like portions FLl-FLS.

Since the cover lock or shroud 10 is substantially the length of the inner book match folder 40 full protection against crushing of the book match is afforded the front panel P3 of the cover lock extends below and covers the striking surface material S on the short front panel 41 of the matchbook so that it is protected from moisture and dirt. The front and rear panels of the cover lock 10 form with the matchbook panels a double thickness front and rear wall against the matches themselves.

The notch 26 exposes a lower portion of the inner matchbook for engagement by a thumb of a user as shown in FIG. 6 to facilitate removal of the matchbook from the cover lock. In addition, any one of springy flaplike portions FLl-FLS of the cover lock 10 provided by the slits S1-S4 can be bent inwardly or outwardly to facilitate getting a good grip on side ends of top panel 47 of the matchbook for removing it from the top open end of the cover lock. This thumb notch 26 is at the center bottom end of the rear outer cover panel to assist in pushing the matchbook from the bottom open end of the cover lock upwardly and outwardly for removal from the cover lock.

FIG. 7 shows a single cover lock 10 in blank form 10a. Parts corresponding to those of cover lock 10 already described are identically numbered. The fold lines F1-F4 are preformed and adhesive layer 25 is applied to the front side 22 of panel P5 to enable it to be secured to 4 the inner side 24 of back panel P1. The slits 81-84 are precut to form the flexible, expandable springy flap-like portions at the top of all the panels P1P5.

FIG. 10 shows an assembly 10b of interconnected separable cover locks 10 in flattened adhered form in which panel P2 is coplanar with panel P3, and panel P4 is coplanar with panel PS. and adhered thereto. Panel P5 is interposed between panels P1 and P3. The cover locks are joined by perforated score lines L1, L2 and L3, FIG. 8, so that the individual cover locks can easily be separated prior to insertion of the matchbook therein.

FIG. 8 shows an assembly 10b of separable, interconnected, flat unadhered blanks 10a. Parts of the cover locks corresponding to those of blank 10a and cover lock 10 are identically numbered.

FIG. 9 shows a step in a process for assembling the assembly 10b of FIG. 10 from the assembly 10b of interconnected blanks 10a of FIG. 8. The flat interconnected blanks are shown being passed between a folding plate 50 to form the fold F3 in a continuous straight line fold throughout the several blanks, whereas the tapered folds F1 are individually folded in a tapered fashion assisted by the slits S1. Some of the panels P1 and P5 of each blank are shown separated from corresponding panels of adjacent blanks only for illustrative purposes to show the ready separability of the several blanks to individual cover locks prior to insertion of the matchbooks.

A multiplicity of assemblies 10b shown in FIG. 10 can be stacked and shipped in compact form. The cover locks are then separated from each other and set up for individual insertion of matchbooks very rapidly and conveniently.

A multiplicity of unadhered blank assemblies 10b of FIG. 8 can also be stacked and shipped in compact form to a point of folding and assembly to form the set-up assemblies 10b. The assemblies 10b and 10b can have any desired length with any desired number of cover locks in each assembly.

FIGS. 11l3 show another cover lock 10c which is similar to cover lock 10 and corresponding parts are identically numbered. A die cut opening 52 can be formed in front panel P3 to expose advertising indicia 54 on the front panel of the matchbook. If desired a transparent window 56 can be applied over the opening 52 to close the front of the cover lock, FIG. 12. Besides offering protection to the matchbook, the window 56 serves as an additional thickness to grip the matchbook in the cover lock.

FIGS. 14 and 15 show a further cover lock 10d which is similar to cover lock 10 and corresponding parts are identically numbered. The front panel P3 is formed with an endless embossment 60 extending inwardly. The embossment serves as a supplementary gripping element to help hold the matchbook in the cover lock by providing added pressure upon the matchbook in addition to the overlapped areas of panels P1 and P5. Furthermore, the embossment can serve as an attractive frame for advertising indicia 62 on the front panel.

FIG. 16 shows a further cover lock 10a in the form of an endless band of sheet or molded plastic in which the top slits may or may not be provided.

In all forms of the assembled cover locks described, there is provided a device which can be reused repeatedly for a succession of matchbooks to keep them closed and protected from dust, moisture and accidental opening.

The cover locks can be made at very low cost by mass production paper, plastic or metal working machinery. They are durable in construction and will provide long useful service. They are inexpensive enough so that they can be given away complete with the matchbooks as advertising novelties or favors.
