Abstract: A phone-on-file opt-in method is described. A phone-on-file opt-in request is received at the billing server including a msisdn and a merchant supplied unique consumer identifier. The billing server confirms the phone-on-file opt-in with a consumer device and records a phone-on-file opt-in status as active if the first phone-on-file is confirmed. A charge method includes receiving, at the billing server, a charge API call from a merchant server including at least one identifier and an amount, determining a phone-on-file opt-in status corresponding to the identifier at the billing server and transmitting a request to charge a user account to a carrier server if the phone-on-file opt-in status is active, but not if the phone-on-file opt-in status is inactive, the request including an amount corresponding to the amount received in the charge API call.

Abstract: The billing gateway charge method and system are disclosed. A charge is processed by receiving a charge API call from a merchant server, detecting a select carrier server from a plurality of servers, transmitting a charge request to the select carrier server, and returning a charge result callback notification to the merchant server. If the charge request fails, the merchant server can submit a new request and an indication of acceptance and failure of the charge request is returned to the merchant server based on the new requests provided that the new request has a new request-id. A continue method allows for managing consumer opt-in in order to complete a transaction. Once the transaction is completed, a refund request from the merchant server can be processed by transmission to the carrier server.

Abstract: A system and method is described for managing subscriptions between a consumer mobile phone, merchant server, billing server and carrier server. A charge-info method is used for the merchant server to retrieve charge elements from the billing server for constructing a user interface for the consumer mobile phone. An opt-in method is used to confirm a consumer's opt-in for a subscription. A remind-charge method is used to remind the consumer of an upcoming charge on the subscription. A charge method allows the merchant server to charge a user account on a carrier server via the billing server. A cancel method is used for the consumer to cancel the subscription.

Abstract: A transaction is authorized by receiving an authorize API call from a merchant server, detecting a select carrier server, and transmitting an authorize request to the select carrier server. The carrier server will then reserve an amount of funds based on the authorization request. The authorized transaction is then recorded based on the authorize request. The consumer may then request to cancel the transaction. If a capture request is received, a determination is made whether the cancel request has been received and whether the authorized transaction has been cancelled. If the transaction has not been cancelled, a billing request is transmitted to the carrier server so that the carrier server charges for the transaction.

Abstract: A sealing structure is provided by an O-ring disposed on a tank, suitable for use in a sprayer, and closed by a cap adapted to carry a pump actuated by a handle which extends into the tank when the cap closes the tank. The O-ring is maintained in a notch between a rim around an open end of a neck of the tank and a shelf extending outwardly from the rim. The cap has a shoulder forming an exterior angle approximately the same as the interior angle between the rim and the shelf on the neck. The shoulder has a chamfered surface which truncates the exterior angle of the shoulder. When the cap is connected to the tank by external threads around the neck and internal threads below the shoulder, the O-ring is compressed in two directions against the rim and against the shelf on the neck of the tank thereby providing an effective compression seal between the cap and the tank.
