Abstract

A container comprises a containment receptable (11) of yielding plastic material which is inserted in a generally box-like rigid supporting shell (12) to project above it with a portion (20) thereof comprising a pouring neck (13). The side wall of said receptable displays projections (14, 15) received in corresponding openings (16, 17) in the shell and preventing withdrawal.

Claims

1. A bottle (10, 110) comprising in combination, an elongate containment receptacle (11, 11'"'"', 111) made of a yielding plastic material and a generally box-like rigid supporting shell (12, 12'"'"', 112), said receptacle having a lower portion thereof inserted in said shell, and an upper portion (20, 20'"'"') comprising a pouring neck (13) projecting above said shell, and characterized in that said lower portion of said receptacle has a generally rectangular configuration thus to form two pairs of spaced, confronting side walls of a different breadth, whereby one of the said pairs of walls is narrower than the other pair thereof, and the narrower side wall pair of said receptacle (11, 11'"'"', 111) having thereon projection (14, 15, 22, 114) received in corresponding registering openings (16, 16'"'"', 17, 116) formed in said shell (12, 12'"'"', 112).

2. Bottle in accordance with claim 1 characterezed in that each of said other pair of said walls of the receptacle have therein spaced, transverse grooves (19, 110) which form thereon spaced, parallel ribs for stiffening said other pair of side walls against deformation forces acting normally on the narrower pair of side walls.

3. Bottle in accordance with claim 2 characterized in that the transverse grooves (19, 119) also constitute means to facilitate folding of the receptacle (11, 11'"'"', 111) longitudinally.

4. Bottle in accordance with claim 1 characterized in that the shell (12, 12'"'"', 112) is provided in the form of a cardboard box.

5. Bottle in accordance with claim 1 characterized in that the upper portion (20, 20'"'"') of the receptacle projecting above said shell (12, 12'"'"', 112) is less yielding than said lower portion thereof (21) that is received in said shell.

6. Bottle in accordance with claim 1 characterized in that the engagement projections have a configuration with widened mushroom head (22) to engage with the edges of the openings (16'"'"') of the shell.

7. Bottle in accordance with claim 1 characterized in that the engagement projections (14, 15) have a form tapered in the direction of insertion of the receptacle (11) in the shell (12) to form a facilitation for introduction of the receptacle (11) in the shell (12) and have thereon a stop against withdrawal of the receptacle (11) from the shell (12).

8. Bottle in accordance with claim 1 characterized in that the receptacle (11, 11'"'"', 111) includes a peripheral stop edge (18, 18'"'"', 118) engageable with the upper edge of the shell (12, 12'"'"', 112) at least on two opposite sides thereof.

9. Bottle in accordance with claim 1 characterized in that the receptacle (11, 11'"'"', 111) has a tapered bottom.

10. Bottle in accordance with claim 1 characterized in that said projections (114) extend longitudinally along the respective walls of said one pair thereof and have lateral undercuts forming grooves (124) for engagement with corresponding lateral edges of the registering openings in said shell.

11. Bottle in accordance with claim 10 characterized in that the openings (116) in said shell are generally in the shape of the letter T to form in the upper transverse part of the T-shaped opening (125) points of facilitation for insertion of the lateral edges of the openings (116) into said grooves (124) in said projections upon insertion of the receptacle (111) into the shell (112).

12. Bottle in accordance with claim 11 characterized in that the projections (114) also are generally in the form of the letter T and each has thereon an upper transverse part (126) disposed to project into and to form an engagement stop in the upper transverse part (125) of the registering opening in said shell.
