Cavanagh, North Attleboro, Mass, assignor to F. H. Buifinton Co., Inc-., Providence, R.I., a corporation of Rhode Island Filed Aug. 21, 1962, Ser. No. 218,263 2 Claims. (Cl. 22031) The present invention relates to a box construction. More particularly, the present invention relates to a box construction having hinged top and bottom sections, the top and bottom sections being formed essentially of nonmetallic materials and being hingedly connected together by a novel hinge assembly.

Display boxes for use in the packaging of small articles, such as jewelry and the like, have normally been fabricated of metal materials. The metal display box has been preferred because of the economies of construction thereof as compared with the wooden box construction that normally requires considerable hand labor and is therefore uneconomical. The metal display box known heretofore also had the advantage of being able to receive the hinge elements that interconnected the top and bottom sections of the display box. However, even the metal display boxes were relatively expensive, and some difficulty has been experienced heretofore with the connection of the hinge elements to the top and bottom sections of the boxes. tofore to fabricate cardboard boxes for use in the display of jewelry items and the like with simplified hinge assemblies, but these prior known box constructions have not been entirely satisfactory since they were difficult to assemble, and the use of some metal materials therein prohibitively increased the cost thereof.

The present invention represents a departure from the prior known box construction and provides an assembly that includes only cardboard and wood materials together with the metal hinges and thereby provides a relatively inexpensive construction that is easy to assembly and durable in use. In carrying out the concept of the present invention, the top and bottom sections are hingedly interconnected together, both the top and bottom sections including an outer shell and an inner shell. The inner shell is confined within the outer shell, but the wall thereof that is adjacent and parallel to the hinge axis of the box construction is spaced from the adjacent wall of the outer shell. An insert member is disposed in the space between the inner and outer shells and is adapted to receive the hinge members therein. The hinge members located in the inserts of both top and bottom sections hingedly interconnect the top and bottom sections which may be provided with an ornamental covering on the outer surface thereof and with interior puffs for completing the assembly of the box.

It is therefore an object of the present invention to provide a box construction that is essentially formed of cardboard and Wood and that is relatively inexpensive and simple to manufacture and assemble.

Another object of the invention is to provide a box construction that includes interconnected top and bottom sections, both of which include inner and outer shells, inserts being located within the inner and outer shells of the sections for hingedly connecting the sections together.

Still another object is to provide a unique hinge assembly for use in a box construction that includes an insert that is disposed between spaced walls of the sections and that has hinge members joined thereto.

Other objects, features and advantages of the invention will become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.

Some etforts have been made here- In the drawings which illustrate the best mode presently contemplated for carrying out the present invention:

Referring now to the drawings, and particularly FIGS. 1 through 5, the box construction embodied herein is generally indicated at 10 and includes a bottom section generally indicated at 12 and a top section generally indicated at 14. The box construction 10 is designed for use primarily as a display box for small articles such as jewelry or the like. However, it is understood that the concept of the invention embodied herein may be utilized in box constructions that are employed for various other purposes.

As will be described, the bottom section 12 and top section 14 will normally include a layer of decorative cloth or paper material indicated at 16. The decorative layer of material 16 covers the outer surfaces of the top and bottom sections Hand 14 and may include any ornamental design or configuration therein as desired.

Referring now particularly to FIGS. 2 and 5, reference will now be made to the construction of the bottom section 12, it being understood that the top section 14 is identically formed. As will be described hereinafter, the top and bottom sections are adapted to be connected together in hinged relation so as to form the complete box construction. As shown more clearly in FIG. 5, the bottom section 12 includes an outer shell 18 that is defined by a bottom wall 20, side walls 22, 24, front wall 26, and rear wall 28. The outer shell 18 is preferably formed of a nonmetallic material, such as cardboard, the outer shell being folded from blank form to the position illustrated in FIG. 3, and the side, front and rear walls being secured in the upright positions thereof by any suitable means. In the upright position of the walls of the outer shell 18, they are located substantially perpendicular with respect to the bottom wall 20.

As will be apparent from the description hereinafter, the outer shell 18 of the bottom section 12 defines the outer case of the bottom section and receives the decorative layer of material 16 directly thereon.

Disposed within the outer shell 18 and completely confined therein is an inner shell 30 that is substantially similar in appearance and construction to the outer shell 18. The inner shell 30 includes a bottom wall 32, side walls 34, 36, front wall 38, and rear Wall 40. The inner shell 30 is formed of a cardboard material similar to that from which the outer shell 18 is formed, and the side walls 34, 36, front wall 38 and rear wall 40 are all disposed in perpendicular relation with respect to the bottom wall 32. The longitudinal dimensions of the front wall 38 and rear wall 40 of the inner shell 30 are slightly less than those of the front and rear walls 26, 28, of the outer shell 18. However, the dimensions of the side walls 34, 36 of the inner shell 30 are somewhat less than the dimensions of the side walls 22, 24 of the outer shell 18. Thus, as illustrated in FIG. 5, when the inner shell 30 is disposed within the outer shell 18, the front walls 26 and 38, the side walls 22, 34 and 24, 36 are all disposed in substantially face-to-face relation. It is, of course, understood that when the inner shell 30 is confined within the outer shell 18, the bottom walls and 32 are located in face-to face engaging relation. Since the lateral dimension of the inner shell as represented by the dimensions of the side walls 34, 36 is somewhat less than the lateral dimension of the outer shell 18, a space is defined by the rear walls 28 and 40 of the outer and inner shells 18, 30, respectively. As will be described below, the space formed by the rear walls 28 and 40 receives an insert member generally indicated at 42.

Referring now to FIGS. 5 and 6, the insert member 42 as shown is defined by an elongated body 44 that has a substantially rectangular cross section and that is preferably formed of a wooden material. The longitudinal dimension of the body 44 is formed such that the insert member 42 will be snugly received between the side walls 22, 24 of the outer shell 18. The lateral dimension of the body 44 is substantially that of the space defined by the rear walls 28 and 40, whereby the insert member 42 is snugly received within the space located between the inner and outer shells.

Formed in the body portion 44 of the insert member 42 and extending through the top wall thereof are slots 46 and 48 that are located in spaced relation with respect to each other. The slots 46 and 48 are preferably formed by a circular saw, the innermost edge of the slots being rounded or arcuate in shape as indicated at 50 in FIG. 6. Formed in the top wall of the body portion 44 and located between the outer limits of the slots 46 and 48 are grooves 52 and 54 that are defined by cutting out a portion of the top wall. The grooves 52 and 54 are stepped with respect to the upper surface of the body portion 44 and are adapted to accommodate a portion of the leaves of a hinge to be described hereinafter. Formed intermediate the grooves 52 and 54 and extending through the slots 46 and 48 are vertical slots 56 and 58. The vertical slots 56, 58 also extend through the front wall of the body portion 44 thereby exposing the interior of the slots. The slots 56, 58 are provided for receiving a spring of the hinge member to be described.

In the assembly of the box construction, the insert member 42 is placed between the walls 28 and 40 of the outer and inner shells prior to the assembly of the hinge member. It will be apparent that both the top and bottom sections are both assembled in the manner just described with the insert members located in their respective assembled positions, and it is in this position that the spring members are secured to the top and bottom sections to hingedly connect these sections together.

Referring now to FIGS. 7, 8 and 9, one of the hinge members is illustrated and is generally indicated at 60. The hinge member 60 is conventional in the manner of use thereof but is somewhat different in configuration so as to be accommodated by the slots 46 and 48 of the insert member 42. The hinge member 60 includes opposed leaves 62 and 64, the outermost edges of which are formed with a generally arcuate configuration. As mentioned above, the arcuate configuration of the leaves 62, 64 is necessary in order for the spring member to be received within the slots 46, 48. The leaf 62 is formed with an inturned inner edge 66 on which are formed hinge knuckles 68. The leaf 64 is similarly formed with an inturned edge 70 on which are formed hinge knuckles 72. A hinge pin 74 extends through the hinge knuckles 68 and 72 and is secured to an endmost hinge knuckle 68 in the well-known manner. Thus, the hinge leaves 62 and 64 are hingedly mounted on the hinge pin 74 so as to be movable relative to each other.

Struck out from the body of the hinge leaves 62 and 64 are projections 76 and 78, respectively, that are adapted to retain the hinge leaves within the slots 46 and 48 when the hinge leaves are inserted within these slots. The projections 76 and 78 are stuck out from the body of the hinge leaves 62, 64 such that a taper is formed, the most outwardly struck portion of each projection being located more closely to the hinge knuckles. When the hinge members are inserted into their respective slots 46, 48, the less tapered end of the projections which are located adjacent the curved outer edges of the hinge leaves are moved through the slots without exerting any appreciable resistance. However, once the hinge members 60 are fully inserted within their respective slots 46, 48, return movement thereof is prevented by the enlarged or most outwardly extending portion of the projections 76, 78. The interaction of the projections 76, 78 with respect to the slots into which they are inserted is shown more clearly in FIG. 7.

Formed intermediate the hinge leaves 62, 64 and in opposed relation are cutout portions 80 and 82. A bowed spring member 84 having inturned edges 86 and 88 interconnects the hinge leaves 62, 64 and is disposed in the cutout portions 80, 82, the inturned ends 86, 88 overlapping the inner edge of the cutout portions to anchor the spring member in position. It is apparent that the spring member 84 will provide for a positive opening or closing of the top section 14 with respect to the bottom section 12 when the top and bottom sections are hingedly connected together.

In the assembly of the box construction 10, the bottom and top sections 12 and 14 are assembled independently. Thus, the bottom section i assembled by placing the inner shell 30 within the outer shell 18 and then disposing the insert member 42 between the spaced walls 28 and 40. The top section 14 is similarly assembled, and the inner shell is located within the outer shell for receiving the lnsert member therebetween. With the top and bottom sections preassembled as indicated, the hinge members 60 are then inserted into the slots 46 and 48 of both the top and bottom sections. In order to carry out this assembly, the hinge leaf 64 of each hinge member 60 is thrust into the slots 46, 48 with the insert member 42 located in the bottom section 12. The hinge leaves 62 of the hinge member 60 are then inserted within the slots 46 and 48 of the top section 14. It is understood that once the hinge leaves 62 and 64 are fully thrust within the slots 46 and 48 of the top and bottom sections, the projections 76 and 78 will prevent the withdrawal thereof. Since the slots 46 and 48 are formed with an inner curved edge 50, the slots will accommodate the curved outer edges of the hinge leaves. The groove 52 acts to seat the edge 70 of the hinge member 60, while a corresponding groove formed in the insert member 42 of the top section 14 seats the edge 66 of the hinge member 60. The edges 66 and 70 of the other hinge member 60 are seated by the groove 54 of the insert member 42 and in a corresponding groove formed in the insert member of the top section 14. The slots 56 and 58 formed in the insert member 42 accommodate the spring members 84 of each hinge member 60. The hinge members 60 are thus positively located in position in the insert members 42, and since the insert members 42 are placed between the inner and outer shells of the top and bottom sections, the top and bottom sections 14 and 12 are located in hinged relation. After the assembly of the top and bottom sections as described above, the outer decorative layer 16 is applied thereto, the outer decorative layer 16 further acting to seal the insert members 42 within their respective sections. In this connection and as shown in FIG. 2, the decorative layer of each section overlaps the walls 28 and 40 of the outer and inner shells and the insert member 42, leaving only the hinge member 60 exposed. The outer decorative layer 16 may be of any suitable material, such as ornamental cloth or paper, and may be glued or otherwise applied to the surfaces of the top and bottom sections. It is also understood that once the top and bottom sections are assembled, interior puffs may be placed therein for completing the ornamental appearance thereof.

It is seen that the unique construction of the top and bottom sections that include the inner and outer shells, the insert members 42 and the hinge members 60 provides for a simple and inexpensive construction. The finished box construction ha all the characteristics of the prior known metal box and has the advantage of being light in weight, simple in construction and easy to fabricate.

While there is shown and described herein certain specific structure embodyu'ng the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
