ATTORNEYS Patented July 27, 1937 BOX William Kaufman, Newark, N. J assignor to Jiife Container Box Company, Newark, N. J., a corporation of New Jersey Application August 15, 1935, Serial No. 36,248
3 Claims. (01. 229-44.)
This invention relates to boxes, containers and the like and refers more particularly to a cardboard box which may be made of a single blank.
An object of the present invention is the provision of a box which is preferably made of a single piece of material, such as a cardboard blank, and which is provided with at least two lids or covers which are conveniently disposed in relation to the main body of the container.
Another object is the provision of a container, the contents and/or the interior of which may be conveniently inspected and which is provided for that purpose, in addition to the usual top cover,
with a front lid which may be opened or closed independently of the top cover.
1 The above and. other objects of the invention -rnay be realized through the provision of a container or box comprising a top cover which can loeyraised or lowered in relation to the main body .of; tho container and an edge of which is in abutment with an edge of a movable front wall while the container is closed. The movable front wall isyconnected to the bottom of the container and may be opened or close-d independently of said- .cover. 1 The invention will appear more clearly from the following detailed description when taken in connejction with the accompanying drawings .showing by .Way of example a preferred embodimentof the inventive idea.
In the drawings:
. Figure 1 is a perspective view of the closed bOX. L
Figure 2 is a perspective view of the box with its side wall'open,
Figure 3 is a perspective view of the box with its coverl'ope'n.q.
Fig. 4 is a perspective View showing the box with both its front Wall and its cover open.
Fig. 5 illustrates the blank which when folded forms; the box shown on Figures 1 to 4 of the drawings.
Fig. 6 is a section along the line 6-6 of Figure 3 on a larger scale.
The box illustrated in the drawings comprises a bottom II], a side wall II, a rear wall I2 and a side wall I3.
As is apparent from Figure 5 of the drawings, the walls II, I2 and I3 are bent at right angles to bottom III while the box is being manufactured.
The edge I4 of the rear wall I I is glued or connected in some other suitable manner to the edge I5 of the rear wall I2. The edge I6 of the rear wall I2 is connected in the same manner to the" edge I! of the side Wall I 3.
The cover I8 of the box forms a continuation of the side wall II. The cover I8 may be connected by hinges with the wall II, or if the box is made of a single cardboard blank, the
cover I8 may be folded along the line in relation to the side wall II.
A strip I9 consisting of a paper or textile material may be pasted over the edge 20 to prevent tearing. Similar strengthening strip-s 2| may be pasted over the abutting edges I6 and H as well as the abutting edges I4 and I5.
The cover I5 comprises two downturned flanges 22 and 23 which extend at right angles to the surface of the cover i8 and which comprise the edges and 25, respectively, (Fig. 5). These edges 24 and 25 are brought in contact with one another when the flanges 22 and 23 are bent at right angles to the cover I8, and are joined by gluing or the like.
As shown more clearly in Figures 1 and 2 of the drawings, the width of the flanges 22 and 23 is substantially equal to or only somewhat less than the height of the walls l 2 and I3. When the box is closed, the flange Z3 overlaps the wall l3 and covers the major portion of this wall. Similarly, the flange 22 covers the major portion of the rear wall I2.
In a box manufactured in accordance with the present invention, the front wall 26 is made movnected by hingesto the bottom II] or it may be made of the same blank as the bottom It] and folded along the line 21, (Figure 5). A strengthening strip 28 consisting of paper or a fabric may be pasted over the edge 21, as shown in Figures 2 and 4.
While the upper edge 28 of the side wall I3 forms a right angle with the side edge ll of this wall, the edge 29 of the wall I3 forms an obtuse angle with the edge 28. Similarly, the second side edge 39 of the side wall I I forms preferably the same obtuse angle with the folding line 29. Due to this arrangement, the edges 30 and '29 form slanting lines when the box is completed.
The movable front wall 26 comprises two triangular side flanges 3! and 32 and a top flange 33. It will be apparent from Figure 5 of the drawings, that when the side flanges 3| and 32 and the top flange 33 are bent at right angles to the surface of the front wall 26, the edge 34 of the side flange 3| is brought adjacent to the edge 35 of the top flange 33. Similarly the edge 38 of the side flange 32 is brought in contact with the edge 31 of the top flange 33.
The edges 3 and 35 are joined one to the other by gluing or the like. The edges 38 and 3'! are joined one to the other in the same manner.
The angles formed between the edges 38 and 39 of the side flanges 3i and 32 on the one hand, and the folding lines it] and H on the other hand, are complementary to the angles formed between the edges 29 and 39 on one hand and the folding lines 42 and 43 on the other hand. Due to this arrangement the edges 38 and 39 coincide exactly with the edges 3% and 29 when the front wall 26 is closed, as shown in Figures 1 and 3 of the drawings.
The top flange 33 of the movable front wall 26 forms a continuation of the cover 18. When the box is closed, the edge 45 of the top flange 33 coincides exactly with the edge 15 of the cover l8.
Resilient means are preferably used for maintaining the edges 4 38 and 39 of the movable front wall 26 in contact with the edges 45, 3t] and 29 or" the box.
While a number of different means may be used to accomplish the same result, in the example illustrated, such means comprise a pair of rubber bands 46 and 41. The rubber band 46 is passed around the knob 48 carried by the side flange 32 of the movable wall 25 and the knob 49 carried by the side wall I3.
As shown in Figure 6, the knob 49 may be screwed upon a suitable nut 50 passing through an opening formed in the side wall E3.
The side wall I l carries a similar knob 50. The rubber band 47 passes around the knob 50 and a knob i which is carried by the side flange 31 of the movable front wall 26.
The box illustrated in the drawings may be used for a number of different purposes. Due to the provision of a movable front wall 26, the contents of the box may be conveniently inspected and removed without opening the cover l8. This arrangement is particularly advantageous in the case of narrow and long boxes containing a number of objects placed side by side, such as papers, plates and the like.
An important feature of my improved construction resides in the arrangement or relation of the parts with respect to each other so that the elastic means d6, ll has a dead-center position and operates when on one side thereof to hold the movable wall closed against the two adjacent walls H and [3, as shown in Figs. 1 and 3. Further, it will be seen that the elastic means 46, 41 is movable to the other side of the dead-center position upon movement of the movable wall 26 through an angle greater than ninety degrees from its closed position, as shown in Figs. 1 and 3, to its open position, as shown in Figs. 2 and 4, in which case the elastic means operates to hold the movable wall in its open position.
Many different changes may be made in the described construction without departing from the spirit of the present invention. For instance, the box may be made of several separate pieces and out of any suitable material.
What is claimed is:
1. A box and the like, comprising a bottom, three walls firmly connected with said bottom, a cover rotatably connected with one of said walls, said cover comprising two flanges adapted to overlap the other two of said walls when the box is closed, and a fourth wall rotatably connected with said bottom, said fourth wall comprising a top flange having an edge adapted to coincide with an edge of said cover when said box is closed.
2. A box and the like, comprising a bottom, three walls firmly connected with said bottom, a cover rotatably connected with one of said walls, said cover comprising two flanges adapted to overlap the other two of said walls when the box is closed, a fourth wall rotatably connected with said bottom, said fourth wall comprising a top flange having an edge adapted to coincide with an edge of said cover when said box is closed, and side flanges having edges adapted to coincide with edges of two of the other walls when said box is closed; and resilient closing means connected with two of the walls and said side flanges and adapted to maintain said fourth wall in a closed position.
3. A box comprising a bottom and walls, one of said walls being connected to said bottom for pivotal movement with respect thereto from a closed position through an angle greater than ninety degrees to an open position, the respective complementary edges of the movable wall and the two walls adjacent to the movable wall being cut on a bias, said movable wall being provided with a flange forming part of a cover for the box when said movable wall is in its closed position,
elastic means having a dead-center position and operable when on one side thereof to hold the movable wall closed against said two adjacent walls, said elastic means being movable to the other side of said position upon pivotal movement of the movable wall through said angle and operd able thereat to hold the movable Wall in its open position, and a cover for closing said box and having an edge which coincides with the adjacent edge of said movable wall when the cover is in position to close the box.
