The invention concerns a plastic closure part (10) which can be fixed to a container or a further closure part to be fixed to the container, comprising a tubular discharge portion (3) whose cross-section is closed by a membrane (7) which has a tear line (8) extending peripherally over more than 180° along its outer edge and a corresponding method for the production of such a closure. In order to develop a closure part having the features set forth in the opening part of this specification and a method for the production thereof to the effect that the problems occurring upon injection moulding due to narrow flow passages are eliminated it is provided according to the invention that the tear line (8) is formed by a cut introduced into the material of the membrane (7) with a cutting or punching tool.

The present invention provides a liquid replenishment container that replenishes a liquid tank including a liquid supply portion protruding in a first direction with a liquid. The container includes: a container main body capable of storing a liquid; a liquid replenishment nozzle including a first side wall and mountable on the liquid supply portion, the first side wall defining an internal space communicating with the container main body; and a valve body provided in the internal space and causing the liquid supply portion to communicate with the internal space when the liquid replenishment nozzle is mounted. The internal space has a first liquid replenishment flow path formed between the valve body and the first side wall and being constant in cross-section in the first direction, and a second liquid replenishment flow path formed inside the first liquid replenishment flow path and being continuous in the first direction.

A chemical dispensing system can include a docking stating that receives a reservoir containing chemical to be dispensed. The reservoir may have one or more retention tabs which are movable from a first position in which each tab extends radially across at least a portion of the bore to a second position in which each tab is offset relative to the bore. A user can engage the reservoir with the docking station, causing the one or more retention tabs on the reservoir to engage with one or more corresponding retention tab receiving regions. This can cause each retention tab to move from the first position to the second position, thereby dispensing chemical from the bore through a discharge aperture of the docking station. In this way, the contents of the reservoir may be dispensed without the user coming into physical content with the chemical in the reservoir.

Provided is a liquid storage bottle that can ensure sufficient sealing performance when a liquid tank is replenished with a liquid. A liquid storage bottle stores a liquid with which a liquid tank is replenished, has a bottle body and a discharge port that discharges a liquid stored in the bottle body, and has a discharge nozzle in which a liquid injection tube of the liquid tank can be inserted via the discharge port and an annular fixed seal member that is provided to the discharge port and seals a part between the discharge port and the liquid injection tube inserted in the discharge port. The fixed seal member has a plurality of annular seal portions that are arranged apart from each other in the axis direction of a discharge nozzle and are individually in contact with the liquid injection tube inserted in the discharge port.

The internal space has a first liquid replenishment flow path formed between the valve body and the first side wall and being constant in cross-section in the first direction, and a second liquid replenishment flow path formed inside the first liquid replenishment flow path and being continuous in the first direction.

A container cap assembly provides a tamper-evident component for detecting cap integrity on a container includes one or more elongate bridges connecting a tamper-evident ring to a cap. The cap assembly also provides radially-extending links on the cap and the tamper-evident ring to help protect the integrity of the bridges as the cap assembly is applied to a container.

The present invention is an integrated wide-mouth bottle cap with a disposable and breakable inner plug comprising a lower cover, an upper cover and an inner plug. The lower cover comprises an opening. The upper cover extends integrally from one side of the lower cover, and the upper cover rotates relatively to the lower cover to fasten the lower cover and seals the opening. The inner plug integrally extends from the lower cover adjacent to the periphery of opening and seals the opening. The inner plug comprises a tearing zone between the inner plug and the lower cover, the inner plug comprises a tearing member for a user to pull in order to drive the inner plug displacement relative to the lower cover, so as to disengage the inner plug from the lower cover and expose the opening by tearing off the tearing zone.

To provide a spout-equipped container that is excellent in hermetical-sealing performance. The spout-equipped container includes a container and a spout. The spout includes a spout base, an opening element accommodated in a cylinder of the spout base, an activating body which moves the opening element, and a heat sealed sheet which covers an inner opening which fronts an accommodating part in the spout base. The opening element is formed so as not to be get out of the spout base, is formed so as to move toward the heat sealed sheet, and has its center where a spout through hole is formed. The heat sealed sheet is formed so as to be partially torn by the opening element to make the accommodating part of the container and an outer opening of the spout base communicate with outside via the spout through hole of the opening element, and is formed so that an accommodated substance is poured outside.
