a vacuum container and a system which includes a complementary base, including a three-part airway, a sealing lid, and a lid release button. The three-part airway features an internal air chamber, an extraction airway, and a one-way check-valve preventing ambient air from penetrating the internal air chamber through the extraction airway when vacuum sealed. The extraction airway extends between the top and the bottom of the container and includes an internal air extraction outlet, disposed at the top of and within the internal air chamber, and an external air extraction outlet outside the container, disposed at the bottom of the container, and configured to be coupled to an external air pump. A complementary method is also provided.

A lid for a liquid material storage container solves problems of uplift and breakage of the lid, and ensures high efficiency in attachment and detachment operations. The lid includes an upper plate portion covering a flange and a large-diameter opening of a storage cylinder; a plug portion extending downward from a central region of the upper plate portion and plugging the large-diameter opening of the storage cylinder; a pair of first lateral portions coming into contact with lateral surfaces of a pair of short sides of the flange when the lid is closed; a pair of claw portions extending from the pair of first lateral portions toward the plug portion and coming into contact with lower surfaces of the pair of short sides of the flange when the lid is closed; and a push-up operating portion formed in at least one of the pair of first lateral portions.

A cap includes a cap body including a disk-shaped top plate portion and a cylindrical skirt portion provided at a peripheral edge portion of the top plate portion; and a disk-shaped sealing member including a sliding layer and a seal in layer, the sliding layer disposed on the top plate portion side and having a thin portion thinner than at least a center side provided on an outer peripheral edge side, and the sealing layer provided on a main surface opposite to the top plate portion side of the sliding layer and sealing a mouth portion of a can container.

A closure (100) comprising a top wall portion (102), a thread support member (108) extending from said top wall portion disposed with a thread (124), and at least one discrete recess (112) provided on said thread support member. The discrete recess may extend below a surface of and through said thread support member so as to form a fenestration, wherein said fenestration is configured for passage of flowable matter. The thread support member may be provided with a subregion limited by ends of said thread wherein said at least one discrete recess is provided at least partially within said subregion. The discrete recess may be formed as a three dimensional marking.

A cap includes a cap includes a cap body including a disk-shaped top plate portion and a cylindrical skirt portion provided at a peripheral edge portion of the top plate portion; a sealing member provided separately from the cap body in the cap body so as to face the top plate portion, the sealing member having an outer diameter smaller than an inner diameter of the skirt portion; a bead portion provided in the skirt portion, restricting movement of the sealing member in a direction away from the top plate portion, supporting the sealing member, and protruding annularly inward in a radial direction of the skirt portion; and a slit portion provided in the bead portion.

The present invention discloses a thermal cup, which includes a cup body with an opening and a cover, a promoter, a sealing ring and a driver. The cover is covered to the opening. The driver is installed on the top face of the cover, the promoter is installed on the bottom face of the cover, when the cover covers at the opening, the promoter is inside the opening, and a gap is formed among the opening, the top wall of the cover and the promoter, the sealing ring is accommodated in the gap. When close the cover, the driver is rotated to bring the promoter to move upwards, the gap is reduced and the sealing ring seals the gap; when open the cover, the driver is rotated to bring the promoter to move downwards, the sealing ring resets to break the sealed connection of the opening and the cover.

A closure for a container. The closure comprises an end panel, a sidewall depending from the end panel and having an inwardly directed curl, and a sealing compound extending down the inner surface of the sidewall. A plurality of ribs are formed in the sealing compound, spaced apart around the circumference of the sidewall, each rib extending down the sidewall and projecting radially inwardly.

A cap includes a cap body including a top plate portion and a skirt portion; a sealing member that is a separate member from the cap body and is provided in the cap body, the sealing member having an outer diameter smaller than an inner diameter of the skirt portion; a plurality of locking portions provided in a circumferential direction of the skirt portion, and configured to regulate a movement of the sealing member in a direction away from the top plate portion and support the sealing member; and a plurality of regulating portions provided in the circumferential direction of the skirt portion, protruding inward in a radial direction than an inner peripheral surface of the skirt portion, and configured to regulate a radial movement of the sealing member.

A metallic can end having a reclosable opening, a microgap or weakening line provided in the metallic end surface and peripheral about the opening, a sealing frame connected to the end surface and surrounding the opening region, a closure unit connected to the upwardly pivotable metal end region disposed within the microgap or weakening line, that is pivotably attached to the end surface via a pivot bearing. The sealing frame and the closure unit are composed of plastic material and cooperate in a sealing manner with one another via sealing and latching ribs that form sealing edges with associated reception grooves. The metallic can region disposed within the peripheral microgap or weakening line is received and held in the opening region of the end. The sealing edges are configured such that the radially innermost sealing edge still seals when the radially outer sealing edges have just been released.

A food jar is described that may be used to store and transport food items. The food jar includes a container, a lid, and a vent. As the lid is unscrewed from the container, the vent opens to equilibrate air pressure within the container with the atmosphere. The vent relieves high and low pressure within the container. The food jar may also include stopper with a vent. The stopper may include an upper and a lower stopper that form the vent.
