| 220203110 | Flexible, resilient vent closing member | 11 |
| 20120292319 | PRESSURE RELIEF VALVE FOR A PACKAGING CONTAINER - The invention relates to a pressure relief valve ( | 11-22-2012 |
| 20120298661 | BUNGHOLE COVER - Embodiments of a bunghole cover are disclosed. The bunghole cover may have a main body with a lower portion, and the lower portion may be configured to engage a bunghole of a storage drum. The bunghole cover may also have a sealing portion configured to substantially conform around one or more tubes inserted within the bunghole The bunghole cover may also have at least one connection mechanism configured to connect a first portion of the main body to a second portion of the main body. | 11-29-2012 |
| 20130119059 | PACKAGING FOR A CONSUMER PRODUCT - A consumer product comprises a container for packaging a composition having a scent. A removable cap is fitted to the container, with the cap and the container defining a cavity therebetween. The cap has an orifice, for communicating between the cavity and an exterior of the cap, and a manually deformable part which is adapted to be displaceable thereby to displace air from an internal location within the cavity outwardly through the orifice. | 05-16-2013 |
| 20140263315 | Variable Volume Container - A variable volume container comprises a sidewall, a base having a ribbed region, and a diaphragm. The ribbed region has a plurality of concentric ribs extending from the diaphragm, and flexure zones between each rib. The flexure zones allow for accordion-like movement of the diaphragm in response to the internal pressure of the container. The ribs are characterized has having a uniformly arced interior curved surface and a distorted arced exterior curved surface. The ribs are four to eight times the width of the flexure zones, and the flexure zones have an exterior surface shorter than its bottom surface. During vacuum sealing, these features allow the diaphragm to retract upward to reduce the volume of the container while maintaining shape and structural stability of the container. This is especially useful for food packaging operations where containers need to be able to withstand conditions such as high pressure, heat, and/or vacuums. | 09-18-2014 |
| 220203120 | Flexible, ringlike vent closing member (e.g., O-ring) | 1 |
| 20140034642 | SEALING STRUCTURE - The object of the present invention is to provide a sealing structure which enables an insertion member to be removed easily from an inserted member. The sealing structure includes valve body, a mouth ring, an O-ring that is accommodated in an accommodation region formed by an inner peripheral surface of the mouth ring and an outer peripheral surface of the valve body, and prevents the fluid from leaking, and backup rings which are accommodated on both sides of the O-ring in the accommodation region, and restrict a movement of the O-ring. The valve body and the mouth ring are formed with screw parts to be fitted or screwed to each other when they are assembled, and first pressure release grooves are formed in the axial direction so as to extend at least on the inner peripheral surface of the mouth ring between the screw parts and the accommodation region. | 02-06-2014 |
| 220203160 | Resilient sheetlike member closes vent opening | 6 |
| 20130048636 | FLEXIBLE, SELF-VENTING RETORTABLE CONTAINER - Containers are disclosed, as well as multilayer films used in such containers, which advantageously maintain a high seal strength even after being subjected to retort conditions for sterilization. These retortable containers and multilayer films are also beneficially self-venting upon exposure to microwave heating, when the internal container pressure exceeds a threshold value. The self-venting nature of these containers arises from particular sealing characteristics, in which the seal width differs in defined, self-venting seal regions, relative to non-venting seal regions of a given peripheral seal. Particular structural features and geometries of the self-venting seal regions can be used to improve the location of venting and control of the vented gases. | 02-28-2013 |
| 20130284738 | SHEET MATERIAL WITH INTEGRALLY FORMED ONE-WAY VALVE - A sheet material for use in packaging having at least a first layer and at lease a second layer, wherein the first layer and the second layer are bonded together to fabricate the sheet material such that an area between the first layer and the second layer is unbonded so as to create a passageway having at least one opening on a first side of the sheet material and at least one opening on a second side of the sheet material, the passageway being a one-way valve integrally formed by bonding together the first and second layers to form the sheet material. | 10-31-2013 |
| 20130284739 | VENTED STORAGE CONTAINER - The present invention provides methods and systems for a vented storage container that includes a container that has an upper mouth-defining structure, a base, and a plurality of walls extending from the base, forming a cavity therein. The lid is fixable to the upper mouth-defining structure, wherein the lid has a top surface and a bottom surface, and at least one hole formed within the lid. A valve is engaged to the lid and covering the at least one hole. | 10-31-2013 |
| 220203170 | Self-closing aperture in member | 1 |
| 20080302793 | Drinking Container Vent System and Method - The present invention relates to a drinking apparatus including a vent system that removably connects to a drinking container. The vent system is used to form a variety of leak free and essentially vacuum-free drinking containers. The vent system, includes a closure member and a valve, and may be used with an anti-bubble tube. The closure member may be a single member or may be formed of two portions. The valve may be coupled thereto or integrally formed therewith. The anti-bubble tube and valve function as a diving bell to generally prevent liquid from entering the anti-bubble tube. | 12-11-2008 |
| 220203180 | Diaphragm-type member | 2 |
| 20100294764 | LEAK RESISTANT DRINKING CUP - A leak resistant drinking cup has a container with an open top and a lid assembly for removable attachment to the container for selectively closing the open top. The lid assembly includes a liquid discharge member for allowing liquid in the container to exit the cup. A closure member is adapted for placement adjacent the open top of the container when the lid assembly is attached to the container. A flexible diaphragm is moveable between a sealed position and an unsealed position. The diaphragm is moveable from the sealed position to the unsealed portion by a vacuum being applied to the diaphragm by a user sucking on the liquid discharge member. The vacuum causes the diaphragm to flex toward the container and at least in part away from the closure member and thereby move the diaphragm from the sealed position to the unsealed position. | 11-25-2010 |
| 20100294765 | LEAK RESISTANT DRINKING CUP - A leak resistant drinking cup has a container for holding liquid and a lid assembly selectively attachable to the container. A diaphragm of the cup includes a liquid discharge member and a sealing member adapted for movement between a sealed position in which the sealing member blocks the flow of liquid from the container to the liquid discharge member, and an unsealed position in which liquid is permitted to flow from the container to the liquid discharge member. The liquid discharge member and sealing member are formed as one-piece. | 11-25-2010 |
