Definitions

  • This invention relates to a container and, more particularly, to a container having two hinged portions which can lbe held in closed condition by the interengagement of locking walls associated with the portions.
  • One kind of container which is widely used is a cardboard box closed by means of an extension of a side or flap that is bent in such a way that it can be inserted into the box.
  • This method of closure is not perfect because the flap is held in position only by friction, which is not always suicient.
  • opening the box is made more diiiicult, and often it is necessary to use a knife-blade or ones fingernails to lift the flap; ultimately, it causes the container to deteriorate.
  • Another object of this invention is the provision of a container adapted to be formed in one piece of plastic material.
  • a further object of the present invention is the provision of a container having a closure construction that has no complex locking mechanism that is difficult to operate and readily deteriorates.
  • the invention relates to a container consisting of a rst portion and a second portion.
  • Each portion has a main wall and a locking Wall extending from the main wall.
  • the main walls are joined together along a hinge line which is a substantial distance from the locking walls.
  • Each locking wall has two parts that extend at an angle to one another, so that the rst portion and the second portion can be rotated about the hinge line until the locking walls nest together.
  • FIG. 1 is a perspective view in open condition of a container embodying the principles of the present invention
  • FIG. 2 is a perspective vieW of the container in closed condition
  • FIG. 3 is a perspective view of a modified form of the container in closed condition
  • FIG. 4 is an end view of the container of FIG. 1,
  • FIG. 5 is an end view of the container showing a form in which it is manufactured
  • FIG. 6 is an end view of the container showing another form in which it can be manufactured.
  • FIG. 7 is a vertical sectional view of mold used in making the container, showing the container in place in the cavity.
  • the container (which is shown as a box for eyeglasses) comprises two prismatic components or portions, open at one side, having main walls 6, 6. Each of these portions has side walls 2, 2 and 3, 3', and terminates in a longitudinal dihedral locking wall 1, 1.
  • the dihedron or locking wall 1 is formed by two parts 4 and 5 which form between them an angle u.
  • the dihedral locking wall 1 comprises parts 4 and 5', one inclined towards the other at the same angle a.
  • the surfaces 6 and 6 of the base, common for both prisms, are connected along a hinge line 7.
  • a boss 8 is provided to be used as a support for the bridge-piece connecting the two lenses of the spectacles.
  • the case may be designed in such a way thath the prismatic part 1, on the left, comes to encase the right-hand part 1', instead of being inserted into it, as indicated above.
  • the result of superimposing 4 on 5 is the same as 5 on 4'. For this, it is sufficient to have a small dimensional difference between the two prismatic parts.
  • FIG. 3 Another practical embodiment of the invention is shown in FIG. 3 wherein the same principle will be found, but the single hinge line 7 is replaced by a side 11 which is Wider and gives to the assembly a polygonal shape having an almost rectangular cross-section.
  • the side 1 may pivot around the hinge line 10 or 9, or around both, at the same time.
  • FIGS. 4 and 5 The end View shown in FIG. 4, which corresponds to the open container as shown in FIG. 1, could give the impression that molding is not possible because of recessed areas limited, respectively, by the inclined sides 5 and 5 of the dihedrons. But, according to this invention, this problem is solved by making the mold of such shape that the container at the time of molding is open to such a degree that the recessed areas are no longer present. To achieve this (as shown in FIG. 5), it is necessary for each of the dihedral sides 5' and 5 to make an angle which is not less than with a plane P connecting the extreme ridges of the sides 5, 5. It is understood that the angle is measured on the inside of the assembly, i.e., in relation to the imaginary plane P which closes the space 6-7-6.
  • FIG. 7 shows the cross-section of a mold designed according to this invention in Order tO produce the container shown in FIG. 1; the Opening angle during molding will be as shown in FIG. 5. It may be seen that, with this arrangement, the two parts of the mold 12 and 13 iit together perfectly, and they may be easily separated after molding. Withdrawal of the container 4-56- y-5-4 from the mold cavity may be carried out in the usual manner. The necessary condition for this is to ensure that sides 4 and 5 of the left-hand dihedron form an angle exceeding 90 with the parting surface 14 between two parts 12 and 134 of the mold. Also, parts 4 and 5 should be no Aless than 90 in relation to Ithe plane 14. This condition is equivalent to that condition according to which the angle (FIG. should be equal t0 90 or exceed 90.
  • the container be formed of a material such as plastic that will not easily break, i.e., is not brittle; on the other hand, the material should have a degree of resilience to permit the locking sides to snap together adequately.
  • the present invention satisfies the deficiencies of the prior art. It is a new system for closing boxes, cases, or shaped packings, without requiring another separate or additional component, or cutting Oli a part of a case.
  • the container made according to this invention can be closed by the simple pivoting of one of its parts in relation to the other, providing a fitting which gives excellent closure and which does not deteriorate.
  • the subject of this invention has the advantage of being extremely simple, and it can be manufactured in one single operation, if produced by a molding process.
  • the main advantage of this invention consists in the fact that the closure is excellent, and is obtained by the tension (pressure) which has to be applied to separate the two superimposed dihedrons.
  • tension pressure
  • to close or to open a case or box made according tO this invention it is necessary to pass the edge of one of the dihedral sides over the edge of the other dihedral side.
  • the dihedron of the two parts of the side is an obtuse angle; it may, according to requirements, vary between 100 and 170; its most generally used values are between 130 and 160.
  • the dihedral parts of the case may have their convex surfaces directed towards the inside of the case, or towards the outside.
  • the other parts of a container made according to this invention may have any shape as desired;- in fact, as a whole, the case may have the shape of a prism, a parallelepiped, a sphere, a hemisphere, an ellipsoid. It may also incorporate several parts having different shapes. Also, it may have embossings or other reliefs, raised parts, or cavities, of any sort, which might be provided in the sides of the walls, or even, should it be required, in the dihedral parts themselves. It is also Obvious that, when a case is produced by molding, the various shapes mentioned above are or may be such that ⁇ it is possible to withdraw them from the molds without difculty.
  • this invention may be most useful for the production of boxes or cases of a type to be completely closed, it may also be applied for packing purposes, by way of enclosing or enveloping only one part of the object; such packings may have the shape of strips or sleeves surrounding the object to be packed or wrapped, which may protrude at one or on two ends.
  • a container formed'of exible sheet material comprising (a) a first rectangular main wall,
  • a rst side wall joining and integrally formed with the other elongated edge 0f the irst main wall and with the sides opposite Vthe said apices of the two end walls associated with the rst main wall, the first side wall consisting of two rectangular portions integrally formed with and lying at an obtuse angle to each other, the apex of the angle extending parallel to the said other elongated edge of the first main wall with the interior of the angle facing away in a given direction relative to the said hinge, and
  • a second side wall joining and integrally formed with the other elongated edge of the second main wall and with the sides opposite the said apices of the t-wo end walls associated with the second main wall, the second side wall consisting of two rectangular portions integrally formed with and lying at an obtuse angle to each other, 'the apex of the angle extending parallel to the said other elongated edge of the second wall with the interior of the angle facing away from the said direction.
