  • Patent number: 11014718
    Abstract: The present disclosure relates to a plastic valve and method for forming a plastic valve comprising an exterior base layer, an interior bubble layer and an exterior channel layer, wherein a flow channel is formed between the bubble layer and the channel layer. In a first aspect of the disclosure, a rigid or semi-rigid spherical ball travels between first and second ends of a channel molded into the bubble layer, thereby moving between a closed configuration and an open configuration. In a second aspect of the disclosure, a bubble is formed between the bubble layer and the base layer of plastic film, and includes a static planar footprint and a pre-tension height. The channel layer is applied to the bubble layer under tension to form a channel. Applying the channel layer decreases a height of the bubble from the pre-tension height to a post-tension height and increases an internal pressure of the bubble.

    Abstract: The present invention relates to a nozzle structure of a dispenser pump button. According to the present invention, the nozzle structure of the dispenser pump button is designed in such a way that an outer nozzle with a discharge hole forwardly moves by the pressure of the content, and the content is discharged through the discharge hole distanced from an inner nozzle, thereby preventing the deformation of the nozzle. Therefore, the inflow of air into a cosmetic container is blocked, and thus the deterioration of the content can be prevented.

    Abstract: A pump dispenser is intended for oral administration of medicines. A pump receives fluid product through a valved inlet from a container, preferably of the airless type with a follower piston. The dispenser may be a movable-nozzle or fixed-nozzle dispenser. The discharge outlet of the dispenser has a stub nozzle incorporating a closure valve. A spring urges the closure valve forward to close a discharge opening of the stub nozzle. The nozzle attachment is shaped for oral dosing and has an internal rearwardly-projecting actuating structure which, when the nozzle attachment is coupled onto the stub nozzle, pushes the closure valve open. When the nozzle attachment is removed the spring closes the outlet again. Child-resistant features are described for fitting the nozzle attachment to the stub nozzle.

  • Patent number: 7784653
    Abstract: By means of a fluid material discharge device of simple construction, a technique for fluid material discharge is provided which has few or no inadequate discharge, high productivity, and which enables easy modification and adjustment of the amount of fluid material discharge. The fluid material discharge device comprises a nozzle for discharge of fluid material and a filament-shape member inserted into the nozzle for use. The filament-shape member has a tip portion AA, which is exposed outside of the nozzle when no pressure is exerted on the tip of the filament-shape member, a portion BB which can be inserted into the nozzle, and a portion CC, on the side of the filament-shape member opposite the tip portion AA, and being bent from the portion BB. The spring structure of the filament-shape member is utilized to discharge fluid material.

  • Patent number: 7731067
    Abstract: A device for the dosed output of a medium from a container through an opening in an upper housing part. A valve piston tip is associated with said opening for the closing thereof. A piston surface, which is pressed against a spring, is adjacent to the valve piston tip and is used as part of a valve piston, which is sealingly guided in a piston chamber in the upper part of the housing and forms a filling chamber which is connected to the container, between the upper part of the housing and the opening.

  • Patent number: 7721918
    Abstract: The non-vented automatic dispensing cap is generally formed of a body and a retainer cap. The body is threadably secured to a squeezable tube or container. The retainer cap is attached to the body. A pressure chamber is formed between the body and retainer cap. A piston may also form a wall of the pressure chamber. A coil spring or resilient flange holds a valve seated within a dispensing hole extending through the cap. When the tube is squeezed, the product is forced into the pressure chamber expanding the pressure chamber and unseating the valve, thereby allowing product to exit the dispensing opening. Upright, inverted, vented and unvented versions are disclosed.

  • Publication number: 20100059552
    Abstract: A fluid-dispensing valve for dispensing pressurized fluid from a chamber employs a spring plate adjacent to the aperture. The spring plate includes a peripheral rim extending about the aperture, a sealing member abutting the aperture, and a plurality of springs extending from the peripheral rim to the sealing member. These springs bias the sealing member to close the aperture when the fluid pressure is less than a predetermined limit and allow the sealing member to open the aperture when the fluid pressure exceeds the limit.

    Abstract: A tube-type container having a check function is filled with liquid contents irrespective of the magnitude of viscosity, prevent air flowing inside the container when the liquid contents are used. The container includes a body, an extension tube, a discharge cap, a cover, wings, a fixing member, an operating member, and a spring. The wings are inwardly protrudently formed on the inner wall of the discharge cap and regularly spaced apart from each other, a space formed between the wings. The fixing member is fitted into the wings. The operating member is configured in such way that its upper end is inserted into the fixing member and its lower end forms a closing plate for closing the passage. The spring is placed between the operating member and the fixing member for allowing the operating member to elastically tightly close the passage.

  • Patent number: 7520408
    Abstract: A hot glue gun having a no-drip tip 20 comprised of a self-closing tip once the trigger 24 mechanism is disengaged which incorporates a mechanism for advancing 24 the glue cartridge 22 forward which opens the self-closing tip 30, a mechanism for retracting 44 the glue cartridge once the trigger is released and a mechanism for closing 46 the self-closing tip as the glue cartridge is retracted thereby preventing further glue 26 discharge. Apparatus 10 incorporates an interiorly disposed cone shaped tip 20 having a tensioning mechanism 46 keeping the tip halves 54 closed until a predetermined pressure is applied to the trigger 24 whereupon the glue cartridge 22 is advanced forcing the interior tip halves 54 to diverge allowing passage of the adhesive. Once pressure is removed from the trigger 24 a spring 44 abutting the glue canister cartridge 22 and the back end of the self-closing tip moves the cartridge to a tip disengaged position thereby providing for the tip tensioning members to close the no-drip tip 20.
