A venting cap liner has a bottom surface facing an annular bottle lip surrounding an open top end of a bottle neck, and a top surface facing an inner top wall of a closure cap, the liner being configured to provide a gas-permeable but liquid-impervious seal that is resistant to rupture when a downwardly directed torque is applied in a thickness direction of the liner body to compression seal the liner body between the annular bottle lip and the inner top wall of the cap. In one embodiment, a two-layer liner body includes a bottom layer of a mineral-filler based polyolefin (MFP) material that is substantially liquid-impervious while allowing release of gas evolving from a liquid product in the bottle, and a top layer comprising a polyolefin (PO) foam material having a grooved upper surface with channels facing the inner top wall of the cap, and a plurality of through-holes extending in a thickness direction, wherein the layers of the liner body allow gas, evolving from a product in the sealed bottle, to permeate out the open top end of the bottle neck, through the MFP material, the through-holes of the PO foam material and along the channels to flow out of an area between an exterior surface of the bottle neck and a peripheral cap flange.

A cap configured to be detachably attached to a mouth portion of a container body having a containment space for contents and close the mouth portion, includes: a transparent or semitransparent topped tubular outer lid portion; and a topped tubular inner lid portion located in close contact with an inner side of the outer lid portion so as to be relatively non-rotatable. A retaining protrusion having an inclined surface that is inclined inward in a downward direction and extends to a lower end of the outer lid portion is provided on an inner peripheral surface of the outer lid portion. The retaining protrusion engages with a retaining depression provided on an outer peripheral surface of the inner lid portion, to suppress separation between the outer lid portion and the inner lid portion.

A shaker top for dispensing products in a container, including a top unit having a peelable protective cover affixed upon a dispensing liner having at least one perforation, the top unit affixed to a mouth of a container. A method of manufacturing a shaker top with a peelable protective cover, including the steps of affixing a peelable protective cover upon a dispensing liner, assembling a top unit including the peelable protective cover and the dispensing liner, affixing the top unit to a mouth of a container, and covering the container with a cap. A shaker top with a peelable protective cover attached to a container, manufactured by the method of manufacture. A method of using a container having a shaker top with a freshness seal.

A cap configured to be detachably attached to a mouth portion of a container body having a containment space for contents and close the mouth portion, includes: a transparent or semitransparent topped tubular outer lid portion; and a topped tubular inner lid portion located in close contact with an inner side of the outer lid portion so as to be relatively non-rotatable. A retaining protrusion having an inclined surface that is inclined inward in a downward direction and extends to a lower end of the outer lid portion is provided on an inner peripheral surface of the outer lid portion. The retaining protrusion engages with a retaining depression provided on an outer peripheral surface of the inner lid portion, to suppress separation between the outer lid portion and the inner lid portion.

An airtight container including a container body having a neck with an opening at one end, a cap having inside a portion having a convex lower end side and attaches to the neck, and a packing. A vertical cross-section of a mouth of the opening forms an upwardly convex curve. The packing has a first concave portion formed on the outer rim of the upper surface, a second concave portion formed on the lower surface sharing a bottom with the first concave portion, and a bent portion radially outboard of the center of the packing and radially inboard of the first and second concave portions are formed, to generate stress that widens the first concave portion and narrows the second concave portion when the cap is attached and the inner surface of the second concave portion is contacted against the mouth of the opening of the neck.

The inventive disclosures described herein pertain to an improved tamper-resistant/tamper-evident (TE) seal for containers of consumer-product-containment vessels (such as, for example, prescription bottles, condiment bottles, etc.) that enables a user to better grip and/or exert force/leverage to more-easily and reliably open such containers. Specifically, it features an improved seal-removal assembly that provides a collapsible finger-receiving aperture that allows a user to insert at least one user finger (or an elongated tool, such as a writing utensil), and exert upward force to breach the container seal.

The invention relates to a cosmetics container, in particular a mascara container (400), whose components are a container part (401), a container cap (402), a wiper, which is inserted into a container neck disposed on a container part, and an applicator (403), which is connected to the container cap and passes through the wiper with a brush rod provided with an applicator brush on its free end. The wiper is made of a plastic material in contrast to at least one of the other previously mentioned components, material intersections, which are realised as detachable form-fit, detachable substance-to-substance or detachable force-fit connections, being formed least partially between the different materials for separation purposes.

A spout cap is a spout cap for closing a mouth portion of a spout main body, and includes a cylindrical body portion made of resin, and a sealing film joined to the body portion, in which the sealing film has a thermal bonding layer which is configured to join to a distal end surface of the mouth portion when the mouth portion is closed.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

A cap. The cap comprises an outer cover, an inner cover, an inner container, and a base. The outer cover comprises an outer cover top and an outer cover body protruding from the outer cover top, and the outer cover top and the outer cover body form an inner cavity. The inner cover is set in the inner cavity of said outer cover, and a first female thread is set on the inner circumference of the inner cover body; a first male thread is set on the outer circumference of the inner container body, the first male thread matching the first female thread. The base comprises a base top and a base body protruding from the base top, a second female thread is set on the inner circumference of the base body, and the base top is connected to the inner container bottom of the inner container.
