Abstract: A hole plug has a head portion, a leg portion protruding from the head portion, and a flange portion protruding on an upper circumference of the leg portion. The leg portion includes an inner wall having an approximately cylindrical shape and connected to the head portion; and an outer wall extending along the inner wall with a gap among the inner wall from a folded portion provided in an end portion of the inner wall, and forming a bendable thin-walled portion. The thin-walled portion is elastically bent by an external force to be capable of transitioning from a first usage aspect in which the outer wall is locked in the hole with the thin-walled portion being in a non-bending state to a second usage aspect in which a force larger than the first usage aspect is provided to pressure contact relative to the hole.

Abstract: A stopper includes a hollow casing with a resilient, ribbed sleeve that forms a valve seat. An interior plunger has a tip configured to mesh with the valve seat when in its down position and to open the valve when in its up position. An upper flange in the plunger provides an additional seal and is visible through a transparent wall in the casing. A vacuum in the bottle draws the plunger downward increasing the pressure with which the plunger presses against the seat, thus securing a long-lasting seal that maintains the vacuum in the bottle. When the vacuum is released, the resilience of the seat structure pushes the plunger upward, rendering it visible as an indicator of vacuum through the transparent wall. An opening in the casing allows connection to a pump to create the vacuum in the bottle.

Abstract: A segmented collapsible container for containing a liquid and collapsing when no liquid is present. The container is segmented into a first portion, a second portion, and a third portion. The three segmented portions form a uniform annular sidewall, with each separate portion of the sidewall having a different thickness or material than the other portions. The middle second portion includes a relatively thinner break point in the sidewall to facilitate collapsing. It is this variation in rigidity and integrity of the sidewalls that allows the segmented collapsible container to collapse. The segmented collapsible container includes an airtight seal formed in the first portion that restricts fluids, such as but not limited to, air from entering or leaving the segmented collapsible container. The segmented collapsible container may more easily return to its original shape after collapsing. This facilitates cleaning and reusability of the container.

Abstract: The invention relates to a closure cap for a bottle or like containers, having an internally-threaded cylindrical part for screwing onto an externally threaded bottleneck, and with a sealing member, separate from the cylindrical part and connected to the cylindrical part, being provided with an annular sealing surface to abut upon the mouth of the bottleneck. The sealing member pivots around a rotational axis which is located in a plane perpendicular to the axis of the cylindrical part, and located radially inwards of the annular sealing surface. By unscrewing the screw-type closure cap, the disc-like sealing member tilts, thus allowing the contents of the bottle to be poured out without the screw-type closure cap being completely screwed off. Thus, the cap is prevented from falling down and being soiled, or from getting lost. By opening the screw-type closure cap to different extent, it is, moreover, possible to adjust the cross-section for the outflow and, thus, to control the quantity delivered.

Valve means cooperates with valve seat for closing off the passageway when the first annular member is in a closed position.

Abstract: A closure for a teat cup with a resilient inner liner in the shape of a small disk with a centrally located bulge. A farmer who has to milk fewer than four teats on any cow because of injury to or disease in one of them can utilize the closure to adapt an automatic milking machine of the conventional type to harvest her milk. The disk is large enough to cover the opening in the teat cup liner otherwise provided for the reception of a teat so that the flow of air therethrough can be cut off when a vacuum is applied to the passageway which terminates in this opening. The bulge with its gently sloping, raised surface increases the area of contact between the disk and the lip of the liner to aid in sealing the disk to the cup under vacuum conditions and prevents the disk from slipping sideways. A magnet secured to the back side of the closure, opposite the bulge, facilitates storage.
