Abstract

A bottle cap assembly, comprising a main portion, and a lid. The main portion and lid are attached by a hinge. The main portion is selectively secured to the lid with a latch, the latch opposite the hinge. The main portion has a central bore, and the hinge has a plug which fits in the central bore when the cap is closed. The central bore has internal grooves, and the plug has protuberances which match the internal grooves to effect a tight seal between the central bore and plug. The main portion further has an upper groove, and the lid has a ring which fits in the upper groove. The ring is larger in diameter and concentric with the plug. At least one opening preventer attaches between the lid and main portion to prevent inadvertant opening of the bottle and for revealing tampering to the bottle, since the opening preventer can be opened once, and then cannot be restored.

Claims

1. A bottle cap, for attaching on a soda bottle having a bottle interior and providing selective access to said bottle interior, the bottle having a top, said top having an opening, comprising:

a main portion, said main portion having an attachment device for attaching over said top and forming a tight seal thereon, the main portion having a central bore in communication with the opening and the bottle interior, the main portion has an upper surface, said upper surface having an upper groove, said upper groove larger in diameter than the central bore and concentric therewith;

a lid, said lid attached to the main portion with a hinge, said lid having a plug which fits within the central bore, said lid has a ring, said ring equal in diameter to the upper groove, larger in diameter than the plug and concentric therewith;

a latch mechanism for securing the lid to the main portion at a point opposite the hinge;

a sealing mechanism between said lid and said main portion for providing a fluid and gaseous seal therebetween, the sealing has at least two circular grooves, concentric and vertically arranged along the central bore of the main portion, the plug has curved protuberances which match the grooves, the protuberances fit within the grooves to form a tight seal between the main portion and lid; and

an opening preventer, having a protection seal, said preventer sealing the lid to the main portion until the protection seal is broken, the protection seal easily breakable with force exerted by a human hand upon the lid, but having sufficient strength to withstand internal pressure from the bottle interior, said protection seal further having;

a transverse bar, said bar extending horizontally and tangentially to the outer circumference, said bar spaced a small distance from the outer circumference;

a tab attached to the lid, the tab extending between the transverse bar and outer circumference, the tab having a tab hook located on the tab opposite the lid, the tab hook preventing the lid from motion relative to the main portion until the protection seal is broken.

2. The bottle cap as recited in claim 1, wherein said latch mechanism comprises a latch, said latch having a latch hook located on the latch opposite the lid, the latch mechanism further having a latch recess and a finger recess in the main portion, a catch is located between the latch recess and finger recess, when securing the lid to the main portion, the latch extends in the latch recess, and the latch hook holds fast at the catch.

3. The bottle cap as recited in claim 2, wherein the main portion has an outer circumference, and wherein the latch is flush with the outer circumference when the latch extends in the latch recess.

4. The bottle cap as recited in claim 3, wherein the attachment mechanism further comprises a threaded neck on the bottle, and wherein the central bore threads onto the threaded neck.

5. The bottle cap as recited in claim 4, wherein the threaded neck comprises broken threads, and the central bore has matching broken threads, the broken threads of the bottle thread onto the matching broken threads of the central bore but do not allow the matching broken threads to be subsequently un-threaded from the bottle.

6. The bottle cap as recited in claim 5, wherein the upper groove has a mouth and wherein the upper groove has a cross sectional characteristic such that it is narrower at the mouth than within the groove, and the outer ring is wider opposite the lid to provide a locking fit when the outer ring is inserted into the upper groove.

7. The bottle cap as recited in claim 1, wherein the upper groove has a mouth and wherein the upper groove has a cross sectional characteristic such that it is narrower at the mouth than within the groove, and the outer ring is wider opposite the lid to provide a locking fit when the outer ring is inserted into the upper groove.
