Shaped caps and containers
First Claim
1. In a container having a non-circular container body and a non-circular cap and guide means for ensuring repeatable helical movement of the cap about an axis of rotation and relative to the container body during sealing of an outlet of the container by the cap, the improvement comprising abutment means on the container and stop means on the cap, the abutment means and stop means comprising respective faces repeatably cooperating to define a predetermined orientation of the cap relative to the body of the container at the termination of the said helical sealing movement and said cap being a two-part cap having an inner and an outer part, the inner part engaging with the container by said guide means and the outer part being separate from the inner part, driving means for interengaging the inner and outer parts and for permitting relative slippage between the same, said driving means comprising a first portion on said outer part and a second portion on said inner part, said outer part bearing said stop means and said inner part including sealing means for sealing the outlet.

Abstract
An abutment face is provided in or adjacent the shoulder of a bottle or other container onto the neck of which a cap is screwed to seal the bottle. The cap has two parts--an inner part which screw-threadedly engages the neck and resiliently seals with it; and an outer part which is in driving engagement with the inner part. In order to ensure proper orientation of the outer part with the body of the bottle (if for example a flat surface on the outer part is to be aligned with a flat surface on the body of the bottle) while still ensuring a seal between the inner part and the bottle, a stop face is provided inside the outer part and, when the inner part has already sealed, abuts with the abutment face to cause such orientation. Upon initial capping of the bottle, the inner part is screwed tight onto the neck and the outer part is then forced over the inner part in a proper orientation until engagement between them is established.

- 1. In a container having a non-circular container body and a non-circular cap and guide means for ensuring repeatable helical movement of the cap about an axis of rotation and relative to the container body during sealing of an outlet of the container by the cap, the improvement comprising abutment means on the container and stop means on the cap, the abutment means and stop means comprising respective faces repeatably cooperating to define a predetermined orientation of the cap relative to the body of the container at the termination of the said helical sealing movement and said cap being a two-part cap having an inner and an outer part, the inner part engaging with the container by said guide means and the outer part being separate from the inner part, driving means for interengaging the inner and outer parts and for permitting relative slippage between the same, said driving means comprising a first portion on said outer part and a second portion on said inner part, said outer part bearing said stop means and said inner part including sealing means for sealing the outlet.
- 6. A container comprising a container body, a hollow cylindrical neck extending from the body, screw-threading externally of the neck, a cap engaged on the neck by said screw-threading, an outlet from the container at the end of the neck remote from the body, the cap having an inner part and a separate outer part, the cap inner part being internally screw-threaded to cooperate with the said screw-threading of the neck to induce movement of said cap along a helical path about said neck when the cap is rotated and the cap inner part also comprising yieldable means for sealing the outlet, the cap outer part comprising means for drivingly engaging the cap inner part for rotation of the two cap parts together in their helical path and also comprising a stop face projecting radially toward the neck and at an end portion of the cap outer part adjacent the body of the container, and an abutment face projecting radially outwardly from the neck of the container into the helical path of the stop face in a final revolution only of the latter, whereby to block revolution of the cap in a repeatable predetermined orientation of the latter relative to the body of the container when said cap inner part sealing means are sealing the outlet, said means for drivingly engaging comprises axially aligned splines on said inner part and said outer part, which cooperatively interact for rotation of the two cap parts and permit relative slippage between the same.
