A bottle cap mechanism comprising a bottle cap body and a label ring that is locked inside the bottle cap body, wherein the bottle cap body includes an outer wall layer and an inner wall layer inside the outer wall layer, wherein the label ring card fits into the inner space formed by the outer wall layer and the inner wall layer; at least one label hole for exposing label information is provided on the outer wall layer.

A resealable cap having a valve-type plug incorporated therein, and a device for manipulating the valve-type plug into a closed, sealed, position to maintain a decreased pressure in a container.

A container and a container engaging member. The container engaging member may include a sample holder or reservoir, a filtration element and collar. In the assembled condition, the sample holder or reservoir is upstream of the filtration element, the container is downstream of the filtration element, and the sample holder or reservoir is attached to the container. The container engagement member is engageable and disengageable from the bottle or container in a quick attach, quick release manner, such as with only a 90 degree, ¼ turn. A tactile and/or audible indication that the engagement is complete is provided.

Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.

A screw cap (14, 502) configured to be removably attachable to a bottle (12) includes a base (40) and an annular skirt (42, 508) extending downwardly therefrom. One or more threads (32) extend radially inwardly from an interior surface of the skirt (42, 508). A retention feature (509) extends radially inwardly from the interior surface of the skirt (42, 508). The retention feature (509) is configured to produce at least one of an audible response or a tactile response when the cap (14, 502) is rotated with respect to a bottle (12).

A resealable cap having a valve-type plug incorporated therein, and a device for manipulating the valve-type plug into a closed, sealed, position to maintain a decreased pressure in a container.

Examples herein relate generally to reservoirs for use in water distribution systems within an appliance. The reservoir herein allows for the combination of various components prepared by separate manufacturing processes and for reducing waste of those manufacturing components. Specifically, the reservoir herein provides a stopper separable from and for use with a container and a cap.

A delaminatable container excellent in productivity is provided. According to an exemplary aspect, a delaminatable container, includes a container body having an outer shell and an inner bag, the inner bag delaminating from the outer shell and being shrunk with a decrease in contents, wherein the container body includes a bottom seal protrusion protruding from a bottom surface of a storage portion to store the contents, and the bottom seal protrusion is a sealing portion of, in blow molding using a cylindrical laminated parison provided with an outer layer constituting the outer shell and an inner layer constituting the inner bag, the laminated parison and is bent.

A cap for engagement with a beverage container allows an extractor needle or other conduit to pass through a portion of the cap such that beverage can be removed from the container without removing the cap. The cap may include a septum that is radially and/or axially compressed and a barrier layer arranged to engage with the container to form a seal.

The present application relates to a bottle comprising a reservoir, a first opening on a first end of the bottle providing access to the reservoir, a second opening on a second end of the bottle providing access to the reservoir; and a removable base covering the second opening.
