A liquid ejection head includes: a casing, which is hollow, and has an opening at one end; a lid member, which is fixed to an end portion of the opening of the casing; and a member arranged inside the casing. The lid member has a liquid supply port. The member has a first liquid guide groove, and the casing has a second liquid guide groove. The second liquid guide groove extends from the end portion of the opening to a side opposite to the opening in the side wall inner surface of the casing, the first liquid guide groove extends to a side surface of the member which is in contact with or close to the side wall inner surface of the casing, and the first liquid guide groove and the second liquid guide groove are located so as to allow fluid communication therebetween.

Liquid ejection head and liquid ejection apparatus

Provided is a method for manufacturing a container including a casing configured to contain a content, the casing including an inner layer having an inner layer opening and an outer layer having an air communication port communicating between a space between the outer layer and the inner layer and the outside. The method includes preparing a casing in which at least part of the inner layer and at least part of the outer layer are in contact with each other, inserting a support column inside the inner layer through the inner layer opening of the prepared casing, and separating the inner layer from the outer layer by supplying air into the space through the air communication port to bring part of the separated inner layer into contact with the support column. The support column includes a columnar portion and an extending portion extending from the columnar portion.

Ink tank for printer

A liquid ejection head includes a housing having a first outer surface; a liquid ejection substrate disposed at a first portion of the first outer surface and having ejection ports for ejecting liquid; and a wiring member disposed on a second portion of the first outer surface so as to be next to the liquid ejection substrate and electrically connected to the liquid ejection substrate. The ejection ports are covered by a cap that is in contact with the wiring member and a portion, except the second portion, of the first outer surface around the liquid ejection substrate; and the second portion is recessed relative to the portion, except the second portion, of the first outer surface around the liquid ejection substrate.

Liquid ejection head and recording apparatus including the same

An inkjet print head is provided with a plurality of electrode terminals connected to a plurality of connecting terminals extending from electrical wiring members transmitting drive signals of elements generating energy for ejecting ink, and an insulating portion for insulating the extending portion of the connecting terminal to the connecting portion where the connecting terminal is connected to the electrode terminal from the print element substrate, the connecting portion being sealed by a sealant spreading due to a capillary force between the plurality of the connecting terminals. In order to prevent occurrence of the non-existence region of the sealant due to the blocking of the sealant by the insulating portion, the insulating portion is constructed of a plurality of separated convex portions in contact with the plurality of the connecting terminals respectively to form a groove between the convex portions for allowing the passing of the sealant.
