molding material and which are provided with partitions and hinge portions formed integral with the receptacle parts during the molding thereof.

In the drawing which shows a container or receptacle constructed in accordance with this invention, and which illustrates but one of the many forms this invention may take,

Fig. 1 is a perspective view of a receptacle or container with the lid or cover in raised position;

Fig. 2 is a central vertical longitudinal section of the container of Fig. 1 with the lid in closed position;

Fig. 3 is a partial vertical longitudinal section .of the container of Fig. 1 with the lid closed, the section being taken at the hinge and drawn to a larger scale;

Fig. 4 is a view similar to Fig. 3 showing a hinge of modified construction; and

Figs. 5 and 6 are partial views in rear and side elevation, respectively, showing a further modification of the hinge structure.

As shown in the drawing a receptacle or container constructed in accordance with this invention comprises a lower or'base portion I-and an upper or cover portion 2, each molded as a unit of a suitable thermal setting plastic molding material. The base portion I comprises-a bottom 3 having a continuous peripheral flange 4 forming the sides and ends of the base portion and partitions 6 extending parallel to both the sides and ends so as to divide the base portion into a plurality of rectangular compartments,

the flange 4 and the partitions 6 being formed integral with the bottom 3 during the molding of the base portion I. At directly opposite points the flange 4 is formed during the molding thereof with outwardly opening recesses 8 which form part of the hinges joining the cover 2 and base I.

The cover 2 comprises a top Ill having a continuous peripheral flange I2 forming sides and ends thereof which overlap the sides and ends of the base I and at points on the flange l2 corresponding to the recesses 8 in the flange 4, the flange I2 is extended to form ears or hingeportions I! having inwardly projecting bosses or abutments I6 which interlock with the recesses 8 and together therewith form hinges which secure the base I and cover 2'together.

The projection'of the bosses or abutments I8 is small and the elasticity of the parts sufllclent to permit of the parts being separately formed and snapped together after the parts have fully set. While the recesses 8 and abutments I6 cause the receptacle parts to interlock with the molds, the elasticity of the material is sufllcient to permit of the parts being readily removed from the molds.

In the structure shown in Fig. 4 the peripheral flange 20 of the base section I is partly cut away on one side of the base section and adjacent each end of that side. At the cut-away portions the flange 28 is thickened forming abutments 2| which extend from the bottom to the top of the flange and reinforce the flange. The abutments 20 and the adjacent portions of the flange form,

the sides of openings which receive the'hlnge lugs 24 formed integral with the peripheral flange 26 on the cover section 2. The hinge lugs 24 are provided with hinge abutments 28 formed integral therewith which engage in recesses 30 formed in the flange 20 of the base section i but .the abutments 28 and recesses 30 may be interextending along one side of the base section I which portion is of substantially semi-cylindrical shape and projectsoutwardly beyond the remainder of the flange on that side of the base section. The ends of the semi-cylindrical portion 32 are flat and are recessed to receive abutments 33 on downwardly extending lugs or ears 34 formed integral with fiat sections 35 which close the ends of a corresponding substantially semi-cylindrical portion 36 of the peripheral flange 38 of the cover section 2. cylindrical portion 36 is of suflicient radius to pass outside of-the portion 32 of the flange 3| when the box or container is opened and is so positioned as to overlie the portion 32 when the box. is closed. I

The base sections I of the receptacles shown in Figs. .4, 5 and 6 will be provided with partitions formed integral therewith during the molding of the sections and the partitions may be arranged as shown in Fig. v1 or in any other manner most; suitable for the purpose'to which the receptacle is to be put.

A container or receptacle constructed in accordance with this invention can be readily made in ornamental colors and shaped or arranged for various uses or to receive various commodities and while particular shapes and arrangements have been shown it is to be understood the in- The semi- 15 a tom, a peripheral flange thereon, a projection of having end walls provided with hinge abutments' adapted to enter the recesses in the ends of the projection on the base section.

2. In a container, a base section having a botsubstantially semi-cylindrical transverse Tcrosssection extending from said peripheral flange with the axis of said projection extending substantially parallel to said flange, said projection having flat end portions provided with recesses to receive hinge abutments;- and a cover section having a top, a peripheral flange thereon, and a resilient projection extending from the peripheral flange of the cover section, said projection having a hollow portion overlying the substantially. semicylindrical projection on the base section and having end walls provided with hinge abutments adapted to enter the recesses in the ends of the projection on the base section.
