Abstract: Cosmetic brush (11) is extensibly received in cosmetic container to pick up cosmetic (2) from lid (1) without being damaged. Lid (1) is engaged with and disengaged from body (10) without fail. Body (10) is constructed of: lift sleeve (14) holding the brush (11); intermediate sleeve (15) with neck (17) cooperating with lid (1) to realize threadable engagement therebetween; and outer sleeve (25) with spiral groove (26) which is a part of a telescopic mechanism for extending and retracting the brush (11) from intermediate sleeve (15). Threadable engagement is larger in frictional resistance than the telescopic mechanism to make it possible: to move first the brush (11) when the lid (1) is rotated; and, then to disengage the lid (1) from intermediate sleeve (15) after the brush (11) press-contacts with the cosmetic (2) and is prevented from moving upward.

Abstract: A liquid container has an automatic opening and closing mechanism preventing entry of air into the container, and is convenient for portable use. The liquid container comprises an upper shell and a lower bonded along their outer circumferential ends to define a flat liquid pool between them. At least one of the upper and lower shells is a thin skin member made of a flexible material to be deformable when depressed. The upper shell has formed a through hole communicating with the liquid pool, and a flexible film is bonded onto the upper shell to form the automatic opening and closing mechanism composed of a duct communicating with the through hole and an outlet communicating with the duct between the flexible film and the upper shell.

Abstract: The liquid-pumping container according to this invention comprises: a container consisting of a flexible bag for containing a liquid substance and an outlet block positioned at the top of the bag and provided with an outlet hole for outlet of the liquid substance, a cover block mounting portion, and a box fixing portion; a cover block which is liquid-tightly mounted on the cover block mounting portion of the outlet block; a pump mechanism provided on the cover block for pumping out the liquid substance from the bag; and a box consisting of a pair of box components which are connected to each other through hinge sections for containing the bag by fixing the outlet block on a support block of the box when the box components are closed. The liquid-pumping container has a structure which simplifies the replacement procedure of the bag containing the liquid substance and reduces the cost of manufacturing.

Abstract: A holder for containing an inner flexible container comprising side walls 15, a bottom wall 16 and a top wall 17 is disclosed. The side walls 15 comprises; a first side wall having a handle 18 projecting in an outer direction, a second side wall having an open window 19 provided in a lower position thereof, a third side wall which is opposite to the second side wall and the upper portion of which has an opening 20 opened to the top end thereof. The top wall 17 has a guide notch which is opened in the opening 20 above the third side wall. The flexible inner container is inserted into the holder in an inclined state through the upper opening 20 of the third side and then is stood in an erect posture, interfitting the mouth of the flexible container into the guide notch of the top wall 17. The contents is dispensed through the mouth by using a torque lowering the side wall which is positioned opposite to the ear 18.

Abstract: A method for manufacturing a three-layered container by injection molding, the method consecutively including steps of:(a) preparing an injection molding apparatus having:an inner injector element having a tubular inner body and a flow path communicating with the inner inlet nozzle and an inner injecting nozzle formed both ends of the body, respectively; andan outer injector element having a tubular outer body including an outer injection nozzle and an outer inlet nozzle, the outer injector element disposed to hold the inner injector element so that a tubular space is formed between the inner and the outer bodies, the inlet nozzle of the outer body communicating with a curved groove formed in the outer surface of the inner injector body; andthe inner surface of the outer body and the outer surface of the inner body are in a form so that the thickness of the tubular space therebetween is smaller at a portion compared to other portions;(b) injecting a first resin from the outer injection nozzle;(c) injecting a

Abstract: A case for a stick-type cosmetic, which includes: a tubular case body having an open end, the body having parallel planar opposite side faces constituting a part of the outer peripheral face thereof, each of the side faces having a through slot; a receptacle for receiving the proximal end of the cosmetic, the receptacle being slidably received in the tubular body; a pair of coaxial pivots connected to the receptacle, the pivots being slidably received respectively in the through slots; and a lid including a head portion and a pair of spaced parallel leg portions, each of the leg portions having outer and inner opposite faces, the leg portions being pivotally connected to the receptacle through the pivots, the lid being movable to a closed position. When the lid is in the closed position, the head portion of the lid closes the open end of the body, and the entire inner faces of the leg portions are mated respectively with the entire side faces of the body.

Abstract: There is disclosed a holder for a stick-type cosmetic case which has an end portion of which the transverse outer size is smaller than that of the other portion of the cosmetic case. The holder includes: a holder body; a cover member; and a slanting surface. The holder body includes bottom and a peripheral walls defining a hollow for receiving the cosmetic case. The peripheral wall includes front and rear portions. The cover member is pivotally connected to the rear portion of the peripheral wall so as to open and close the hollow. The slanting surface extends between the bottom wall and the rear portion of the peripheral wall. The slanting surface inclines in such a manner that its rear edge is positioned at a higher level than its front edge. The distance between the front edge of the slanting surface and the front portion of the peripheral wall is less than the length of the cosmetic case and not less than the length of the other portion of the cosmetic case.

Abstract: A compact costmetic case which includes: a case body; a lid of the case body pivotally connected to the case body and adapted to be unfastenably fastened to the front portion of the peripheral wall of the case body; and a disengaging mechanism for unfastening the lid from the case body. The front portion of the peripheral wall of the case body has a recess having an end surface on which a first engaging member is formed. The lid has a second engaging member adapted to be engaged with the first engaging member. When the lid is in its closed position, the second engaging member is engaged with the first engaging member so that the lid is fastened to the case body. The disengaging mechanism is received in the recess of the case body. The disengaging mechanism has a sliding plate movable between outer and inner positions toward and away from the end surface of the recess.

Abstract: Process and machine for multi-color injection molding of plastic products having three-dimensional appearance of continuous or discontinuous multi-color patterns according to a preset program through injection of various kinds and/or colors of resins into a cavity, the resins being injected from at least three injection units, merged into and blended together in a molten resin mixing manifold. The multi-color injection molding machine has more than three injection units established around the molten resin mixing manifold. The manifold internally holds an arranging chamber, which received a resin from each injection unit and forms a compounded or layered resin flow. For the purpose of presenting intricate multi-color patterns according to a preset program, the arranging chamber is detachably mounted in the molten resin mixing manifold.
