Squeeze container

A squeeze container, comprising:

• a concave storage portion in which a content is stored;
• a sheet-shaped elastic body which is arranged on the storage portion;
• a pressurizer which swells the elastic body to a storage portion side with gas pressure;
• and
• a delivery passage which provides communication between the inside and outside of the storage portion and which delivers the content squeezed by the elastic body to the outside,
• wherein the pressurizer includes a squeeze deformation portion which is deformed by squeezing with a hand and which is returned into an original state by releasing of the squeezing and is structured to be capable of swelling the elastic body by squeezing and deforming the squeeze deformation portion, and
• the squeeze deformation portion has a curved convex face toward the outside of the container and includes a linear reinforcement portion which traverses an apex portion of the squeeze deformation portion, and a linear thin-walled portion which is formed in a direction along a circumferential edge of the squeeze deformation portion.

A squeeze container, comprising:

• a concave storage portion in which a content is stored,
• a sheet-shaped elastic body arranged on the storage portion,
• a pressurizer which swells the elastic body to a storage portion side with air pressure, and
• a delivery passage which provides communication between the inside and outside of the storage portion and which delivers the content squeezed by the elastic body to the outside,
• wherein the pressurizer includes a squeeze deformation portion which is deformed by squeezing with a hand and which is returned into an original state by releasing of the squeezing, and a check valve which opens an intake passage to suck outer air when the squeezing is released, and is structured to be capable of gradually swelling the elastic body by feeding air into an inflation chamber of which part is structured by the elastic body by repeating squeezing and releasing of the squeeze deformation portion,
• an air-bleeding device which discharges air in the inflation chamber to the outside is provided to the container,
• the air-bleeding device includes an elastic member, a plug member and a communication passage which provides communication between the inflation chamber and the outside of the container via a storage portion of the elastic member,
• the plug member closes the communication passage as being urged by the elastic member and opens the communication passage when the plug member is pressurized, and
• the intake passage which is opened and closed by the check valve surrounds a periphery of the air-bleeding device.

A squeeze container, comprising:

• a storage portion in which a content is stored, the storage portion having a delivery passage which provides communication between the inside and outside of the storage portion,
• an inflation chamber, and
• a pressurizer,
• wherein volume of the inflation chamber is increased owing to that the pressurizer fills gas into the inflation chamber and the content in the storage portion is delivered to the outside of the storage portion via the delivery passage owing to increase of the volume of the inflation chamber,
• at least a part of the inflation chamber is structured with an elastic body and the volume of the inflation chamber is increased with deformation of the elastic body while gas is filled into the inflation chamber by the pressurizer,
• an inflation absorbing portion which decreases the volume of the inflation chamber at the time when gas-filling into the inflation chamber by the pressurizer is completed,
• the storage portion is concave and has an opening at an upper face,
• the inflation chamber is structured with a partition wall and the elastic body which is arranged to cover an entirety of the opening,
• the pressurizer includes a pressurization chamber which is structured with the partition wall and a squeeze deformation portion, a first check valve which allows only ventilation toward the inflation chamber from the pressurization chamber, and a second check valve which allows only inflow of outer air into the pressurization chamber, and
• the inflation absorbing portion includes a displacement portion, formed at the partition wall, which is displaced toward a side opposite to the elastic body when squeezing of the squeeze deformation portion is released.

A container adapted to be filled with liquid by an aerosol container, comprising a liquid storage portion with which an amount of the filled liquid is visible from the outside,

• wherein a discharge passage capable of discharging air in the liquid storage portion at the time of filling liquid is arranged at the liquid storage portion,
• the discharge passage is formed to increase air pressure in the liquid storage portion owing to filling of the liquid and to maintain a positive pressure state during filling of the liquid while preventing the liquid in the liquid storage portion from leaking to the outside,
• the liquid storage portion is formed by screwing a container body and a cover body, and
• the discharge passage provides communication between the inside of the liquid storage portion and the outside of the container via a minute gap which is formed between the container body and the cover body by the screwing.
