The cover cap is obtained from a lower cover cap section (3), which is integrated with an output-side passage part (4) and is fixed to the container body (1), and an upper cover cap section (5), which is integrated with an operation section (6) and is rotatable with respect to the lower cover cap section (3). The output-side passage part (4) is provided with: multiple individual passage sections (4c+4g, 4d+4h), which are formed on the downstream-side that is continuous with the external space and are for setting different content release modes (for example, release patterns); and a common upstream-side vertical passage (4b) that is continuous with the stem (2). By a rotating operation between the lower cover cap section (3) and the upper cover cap section (5), an individual passage section that is in communication with the common vertical passage (4b) is selected from among the multiple individual passage sections. When the top plate surface portion (6c) is pressed downward in said configuration, the contents are sprayed into the external space from the selected individual passage section.

CONTENT RELEASE-LOCKING MECHANISM, AND AEROSOL PRODUCT AND PUMP PRODUCT PROVIDED WITH CONTENT RELEASE-LOCKING MECHANISM
The present invention is designed to reliably prevent unintentional operation of a depress-and-rotate-type content release operating part and to stabilize and improve sliding operation of said operating part to select a locked mode or an unlocked mode and depressing operation for releasing the contents. A guide member (2a) is provided with guides (2k, 2n) for guiding the sliding operation of the operating part (1). The operating part (1) is provided with guided parts (1g, 1j), which are respectively guided and held by the guides, and a content passage (3)-driving part (1f). In the locked mode in which the operating part (1) is in a forward position, the guided parts (1g, 1j) are respectively held by the guides (2k, 2n) and content-releasing operation of the operating part is inhibited. In the unlocked mode shown in which the operating part (1) is moved backward, said held sate is cancelled. As a result of a depressing operation of the operating part (1), the operating part rotates centered on the guided part (1g), the driving part (1f) presses a driven part (3d) downward, and the content passage (3) and the stem (4) assume a content-releasing configuration.

ACTUATOR FIXED-QUANTITY INJECTION MECHANISM, AND AEROSOL PRODUCT PROVIDED WITH ACTUATOR FIXED-QUANTITY INJECTION MECHANISM
The present invention is a fixed-quantity injection mechanism that uses an actuator comprising a stem connection member (5) an intermediate mobile member (6), and a fixed-quantity-chamber adjustment member (7). On the basis of an injection operation, by means of first the output valve of the actuator closing and the inflow valve of the stem (4) becoming open, vessel body contents flow into a fixed-quantity chamber (A) from the inflow valve to the output valve, and then the stem (4) returns to a still mode position, closing the inflow valve, and the contents of the fixed-quantity chamber (A) are injected to an outside space through the opened output valve by means of the action of liquefied gas or the like. The capacity of the fixed-quantity chamber (A) changes by means of a rotation operation of the fixed-quantity-chamber adjustment member (7) that is screw-coupled to the intermediate mobile member (6). The inflow valve comprises a stem gasket and a horizontal hole section (4b) of the stem (4), and the output valve comprises a frustroconical section (5a) of the stem connection member (5) and an annular protrusion section (6c) of the intermediate mobile member (6).

CONTAINER COVER AND AEROSOL TYPE PRODUCT PROVIDED WITH CONTAINER COVER
Provided is a container cover for an aerosol type product and a pump type product wherein a content injection port is covered and protected by an operation member in a stationary mode, so that a malfunction of the operation member can be prevented, and the effect of protecting the content injection port, etc. can be assured. The operation member (7) for covering and protecting the content injection port (6c) in the stationary mode is a sliding type, and upon releasing a sliding operation, the operation member automatically and certainly returns to the stationary mode by elastic action of a leaf spring (8). Further, in the stationary mode, the shape of the entirety of the container cover outer surface including the operation member has a single dome shaped appearance. When the operation member is slid toward the right in the drawing, the content injection port is exposed to the external space, and thereafter, a pressing action portion (7g) is pressed on an inclined portion (6d) of a content injection unit (6). By this pressing action, a stem (3) integrated with the content injection unit is moved downward to transfer to an operation mode, and the contents in the container pass through an injection path (6b) and is discharged from the content injection port.

B05B 11/00 - Single-unit hand-held apparatus in which flow of contents is produced by the muscular force of the operator at the moment of use
A content discharge mechanism for a container with a pump has a discharge outlet that is fixed in position. The device has an operation button and a cylindrical piston that move as one, as well as a ball valve that rests on a seat. The ball valve opens as the cylindrical piston retracts after an actuation to allow more fluid into the upstream passage chamber. A downstream passage with a valve for dispensation fluidly communicates with the upstream passage through a hole. As the cylindrical piston and its seal slide over the hole, the discharge from the downstream passage stops.
A pump mechanism for discharging contents has a receiving space region inside a cylinder, and the ratio of pressure reduction in the receiving space region when a piston is returned after content discharge operation is set greater. As a result, force of sucking contents into the receiving space region is increased, and outside inflow operation, a section from which the contents flows into the receiving space region is reliably closed. A multi-function columnar member (8) is provided in the receiving space region (B) of the cylinder (6), and the columnar member (8) is made up of a circular columnar section (8a) for reducing the volume of the receiving space region and of a tubular section (8d) for pressing a lower ball valve (7). The tubular section (8d) has an elastic section (8g) for pressing the ball valve (7) from the above, an inner peripheral surface (8h) for limiting the movement of the lower ball valve in the left-right directions, a vertical groove (8f) for allowing the contents to pass through between inner surfaces, and other element sections. In the state shown in the figure, when an operation button is pressed, an upper valve (5) is separated from a circular conical section (4b) of a lower piston (4), allowing the contents in the receiving space region (B) to flow in the direction of the arrow to discharge the contents to an external space.
A content discharge mechanism for a pump-type container, in which the position of a content discharge opening does not move with discharge operation. In the mechanism, the structure is simplified, the flow of the content is smoother, and the start and completion of content discharge are made in more proper manner. The content discharge mechanism has an operation button (1); a sheath-like piston (2) moving in association with the operation button (1); a suction valve (annular receiving surface (3c) and spherical body (5)) operating with the movement of the sheath-like piston (2); an upstream channel (A) formed between the sheath-like piston (2) and the suction valve; a downstream channel (B) formed as a separate member (lateral nozzle (3e)) from the operation button (1), connecting the upstream channel (A) and a discharge opening (8b), and formed not to move; and a pressure accumulation-type discharge valve (annular edge (8a) and annular tapered surface (9a)) provided in the downstream channel (B). In a discharge completion mode, the downstream channel (B) is communicated through a hole (3f) with a space region (E) outside the channel, and this reduces content pressure acting on the discharge valve, setting the discharge valve in a closed state.
Assembly of a tip-stop mechanism is raised in efficiency and is simplified. An opening is provided in the rear side of a spout (1) attached to a stem of a pump/aerosol container, and a needle valve (2) is installed from the opening into a path region (1f) lying in the front-rear direction. Then a peripheral wall rear cover (3) is attached from the rear to the spout (1). In this process, a leg (3a) is engaged with and held in a recess (1c) of the spout (1), and a sheet spring (3b) comes into contact with a tapered surface (2c) of the needle valve (2). A circular conical section (2a) of the needle valve (2) closes a discharge hole (1h) by an effect of the sheet spring. An operation lever (4) is supported at its rotating shaft (4a) by a recess (1b) of the spout (1). In a stationary mode, a section (4b) of the lever (4) lies on a reception section (2e) of the needle valve (2). When the operation lever (4) is operated, the reception section (2e) receives force from the section (4b), which causes the needle valve (2) to recede to open the discharge hole (1h). After that the operation lever (4) comes into contact with an upper surface (1g) of the spout (1) to move down together with the spout and the stem, shifted into an operation mode.

TIP-STOP MECHANISM, PUMP-TYPE PRODUCT WITH TIP-STOP MECHANISM, AND AEROSOL-TYPE PRODUCT WITH TIP-STOP MECHANISM
A tip-stop mechanism that can be efficiently and easily assembled. The rear side of a spout (1) fitted to the stem of a pump/aerosol container is opened and a needle valve (2) is placed from the opening side into a passage area (1f) formed in the front-rear direction. Next, a peripheral-wall rear cover (3) is fitted to the spout (1) from the rear. As a result, leg parts (3a) are latched and held in recesses (lc) of the spout (1), plate springs (3b) engage the tapered surfaces (2c) of the needle valve (2), and, by the action of the plate springs, the conical portion (2a) of the needle valve (2) closes a discharge hole (lh). When an operation lever (4) that is supported at its pivot shafts (4a) by recesses (lb) of the spout (1) and is in a stationary mode is pivoted, a receiving section (2e) of the needle valve (2) receives force from a portion (4b) of the lever to cause the needle valve (2) to move backward, setting the discharge hole (1h) to an open state. After that, the operation lever (4) engages the upper surface (lg) of the spout (1) and moves downward together with the spout and the stem, thereby the lever (4) is shifted to an operation mode. A tip-stop mechanism in which a vertical motion-type operation button is used is also disclosed.

FLOW RATE REGULATOR UNIT AND AEROSOL-TYPE PRODUCT WITH THE SAME
A flow rate regulation mechanism of a unit structure, in which the mechanism keeps constant the amount of injection of the contents in an aerosol container independent of a variation in pressure of gas for content ejection. A flow rate regulator unit has an outer sheath member (15), an inner sheath member (16), piston members (17, 18), a coil spring (25), and an ejection piece (19). The contents are ejected in substantially the following route: 旜hole (15a) - annular space region (21) for outer path - hole (16a) - annular space region (22) for inner path - holes (17b, 18b) - inside path (18c) - valve action region (20) - penetration section (16d) - groove-like sections (16f, 19a) - ejection hole (19c). ”An annular skirt section (17a) moves in the left-right direction based on a magnitude relation between force in the right direction caused by ejection gas pressure and acting on the piston members (17, 18) and urging force to the left direction caused by the coil spring (25), and this changes an inflow cross-sectional area from the hole (16a) for flow rate adjustment to the annular space region (22) for inner path.
