An object is to provide a cap that can be flexibly designed, such as a cap that can be prevented or reduced from being increased in volume when the lid member has been attached to the cap body, while at the same time providing a capability to increase the distance between the lid member and the cap body when the elastic member has been restored, as well as providing a container equipped with the cap. Provided is a cap and a container with a cap, which includes a cap body (), a lid member (), an elastic member () that couples the lid member () to the cap body (), and a coupling member () that couples the lid member () to the cap body (), in which: the elastic member (), which has been elastically deformed, is restored during at least part of the movement of the lid member () away from the cap body (), thereby enabling the lid member () to be held away from the cap body (); and the coupling member () is connected to the cap body () via a first hinge mechanism () and connected to the lid member () via a second hinge mechanism () that has an axis parallel to an axis of the first hinge mechanism ().

Cap and container with cap

A coating material includes a first aqueous dispersion (A) and a second aqueous dispersion (B) wherein a dispersoid of the first aqueous dispersion (A) has an average particle diameter of 1 to 20 &#x3bc;m and a dispersoid of the second aqueous dispersion (B) has an average particle diameter 1/100 to &#x2155; of that of the dispersoid of the first aqueous dispersion (A), and the mass ratio (the aqueous dispersion (A)/the aqueous dispersion (B)) of the dispersoid of the first aqueous dispersion (A) to the dispersoid of the second aqueous dispersion (B) is 2/1 to 100/1. Also provided is a container, which is coated with the coating material and has excellent properties.

A particularly small eyedropper or the like is provided, which has a construction such that, when a body thereof is squeezed, an introduction hole thereof can be easily closed to compress air in a space between an inner layer and an outer layer thereof even in the absence of a check valve in the introduction hole, and defectiveness of the introduction hole can be easily checked. To this end, a test hole () communicating with an introduction hole () via a space between an outer layer bottle. () and an inner layer bag () is provided in an outer layer mouth portion (). The test hole () is closed by the inner layer bag () and an inside plug () fitted in the mouth portion (). Further, the introduction hole () is provided in a middle portion of a body which is pressed by a finger when the bottle is squeezed. The introduction hole () is closed by the finger.

Production method for a delaminatable laminated bottle

A container cap locking a plug member to a mouth by a locking member and capable of being removed from the mouth together with the plug member by repositioning a holder member. The locking member is covered on the container mouth so as to hold the plug and the holder member is fitted to the outer peripheral sides of a plurality of locking pieces of the locking member. In each locking piece, an upper side part is connected to a lower side part through a thin-walled bending part. The upper side part is locked to the rubber plug from the lower side with the holder member on the outer peripheral side thereof. The lower side part is locked to the container mouth from the lower side by the holder member. Locking projected parts prevent the lower end of the holder member from coming out of the upper side part.

Container cap

An infusion vessel has a vessel body having an internal cavity to serve as an infusion medium space, a cylindrical discharge mouth continuing from a lower portion of the vessel body, a medicine chamber disposed in the discharge mouth and kept airtight against ambient air, and a separator intervening between the infusion medium space and the medicine chamber so as to keep the space in a liquid-tight state against the holder. The separator is subject to displacement, rotation or deformation such as to bring the infusion medium space into communication with the medicine chamber, so that the infusion vessel can be made ready for use by conducting a simple operation to mix the medicine with the infusion medium that have been separated from each other within the vessel during its normal state before use.

Infusion vessel

The present invention provides an infusion vessel, which is capable of separately containing a drug and a infusion liquid in a sterile manner and mixing the drug with the infusion liquid in a sterile manner by a simple operation for use, while ensuring the sterility of a connector thereof. The infusion vessel according to the present invention comprises a bag () for containing a infusion liquid, a two-mouth vial () for containing a drug, and a joint () connecting the bag and the vial. A lower mouth portion () of the vial () is sealed with a rubber plug (). The joint () is air-tightly connected to a liquid outlet port () provided in a bottom portion of the bag (), and extends downward. The joint () has an opening () for communication between the inside and the outside thereof. An O-ring () and an intermediate rubber plug () are respectively attached to the joint () above and below the opening (), and fitted in the upper mouth portion () of the vial () in an axially movable manner.

Discharging container with a filter and a bottle stopper for use in the container

A closing member is equipped with a dispensing valve and a filter The valve is deformed resiliently to shift its valve head downstream with its orifice remaining closed if pressure less than a first predetermined pressure and more than a second predetermined pressure is acted on the inner surface of the valve head The valve returns to its original shape to shift the valve head upstream with its orifice remaining closed if the pressure is removed, thereby sucking fluid remaining within the passage back to the upstream side of the filter The closing member has a supporter that prevents the orifice of the valve head from opening when a negative pressure is generated in the bottle.

Closing structure of a dispensing container

The present invention provides a method of making laminated bottles each having an outer layer and an inner layer capable of delaminating from the former layer. The method consists of the step of injection molding an outer preform from a molten first resin, and the next step of injection molding an inner preform inside the outer preform, using a molten second resin. The method further has the final step of blow molding a parison composed of the outer and inner preforms so as to form each laminated bottle. The second resin has a melting point lower than that of the first resin, nevertheless and contrarily to the prior art, precise parisons affording satisfactory lamination can now be prepared by the injection molding steps. In addition, ventilation holes are formed in the outer layer readily and surely without damaging the inner layer.

Method of producing laminated bottles having peelable inner layer

A pumping container including a laminated bottle having a delaminatable layer with an inner layer portion serving as a valve for closing ventilation holes. The laminated bottle has the inner layer delaminated from an outer layer and formed on its inner surface. A ventilation hole formed in the outer layer allows ambient air to flow in between the outer and inner layers. The ventilation hole in the outer layer is temporarily closed with a closing portion of the inner layer from inside such that this closing portion will be deformed inwards due to atmospheric pressure so as to open the ventilation hole in response to a negative pressure appearing between the layers.
