摘要:
A resealable vacuum-tight closure mechanism comprises a first closure element that includes a first base and a second closure element that includes a second base. A first contact surface on a first interlocking profile depends from the first base and a second contact surface on a second interlocking profile depends from the second base. The first and second contact surfaces provide a maximum occlusion distance when the first and second interlocking profiles are in an occluded state. A first sealing member extends from the first base, has a first length, is spacedly disposed from the first interlocking profile, and has a first sealing surface disposed thereon. A second sealing member extends from the second base, has a second length, is spacedly disposed from the second interlocking profile, and has a second sealing surface disposed thereon that is complementary to the first sealing surface. A sealing reservoir protrusion is disposed between the first sealing member and the first interlocking profile and has a volume sufficient to form a first gastight seal in a first occluded space between the first and second closure elements and bounded by the first and second occluded sealing members and the first and second occluded interlocking profiles upon formation of an end-stomp at an end of the first and second closure elements. A sum of the first and second lengths of the respective first and second sealing members is greater than or about equal to a length necessary to maintain a second gastight seal between the first and second sealing surfaces when the first and second interlocking profiles are in the occluded state.

A cleaning implement is disclosed which is of the all-in-one type. It has a substrate that delivers impregnated cleaning liquid to the window being cleaned, a squeegee blade to drive used cleaning liquid off the window, and an absorbent region of the substrate to collect the used liquid. In some embodiments a single block of substrate can provide the applicator, scrubbing, and collecting functions, as well as filter and reprocess used cleaning liquid for further use. Refill structures are provided to permit insertion of the refill in varied directions, to facilitate insertion and removal of the refill, to increase the abrasive character of the refill, to minimize drooling, and to otherwise optimize cleaning properties of the refill.

A volatile material diffuser includes a housing and first and second containers holding first and second volatile materials and having first and second wicks, respectively, in contact with respective volatile materials and extending out of respective containers, wherein the containers are inserted into and detachably attached to the housing. The diffuser further includes first and second heaters disposed within the housing adjacent the first and second wicks, respectively, to vaporize the first and second volatile materials, respectively. A means for providing an air flow is disposed in the housing such that air from the means for providing an air flow transports vaporized volatile materials away from the housing. The heaters are energized in an alternating sequence such that, when a heater is deactivated, the means for providing an air flow cools a wick associated with the deactivated heater.

A dispersion device for dispersing volatile materials includes a housing and a plurality of receptacles containing volatile material therein. The device also includes a means for generating or permitting two or more airflows that exit the housing and a switch for adjusting the airflows with respect to speed or path. The plurality of receptacles is connected to the housing such that a portion of the volatile material can be placed into one or more airflows.

A replacement device for a light bulb includes a translucent shell and a base. The base supports a plurality of LEDs positioned so as to emit a light show through the shell. The base is configured to be received in a conventional light socket. The base also includes a compartment for receiving and securing a replaceable volatile active cartridge and a heater for enabling the device to effectively emit an active ingredient from the cartridge when the cartridge is secured in the compartment. A white light source is also provided in the shell as a source of illumination. The device can be used as a white light source, for displaying a colored light show and for volatile active emission. The volatile active may be emitted continuously when the device is used as either a white light source or for purposes of displaying a colored light show. Thus, a single device is used as a replacement for a conventional light bulb and is a combination white light source/colored light show source/volatile active source.

A method of producing an electrically charged film includes the steps of forming a molten thermoplastic material into a web, electrically charging the web while the web is at a temperature substantially at or above a solidification temperature thereof, cooling the web below the solidification temperature thereof after charging and winding the web into individual rolls immediately following the cooling step.
摘要:
A closure member for a reclosable thermoplastic bag having opposing rib and groove profiles wherein the rib profile has an longitudinally extending part interlockable and substantially free of interdigitation with the opposing groove profile and wherein the part is deformed defining indentions in the part to provide structural discontinuity along its length. When the rib and groove profiles are interlocked, an audible clicking sound and/or a vibratory or bumpy feel perceptible to the touch is imparted.

A process for providing microperforations in a zippered film useful for manufacturing reclosable zippered produce bags including the steps of(a) providing a web of thermoplastic film with zipper profile members on at least one side of the web, the zipper profile members spaced apart on the web forming a central web area between the profiles;(b) feeding the web between the nip of a cylinder having a plurality of heated pins and a pressure roller such that a plurality of microholes are formed in the central web area between the zipper profile members; and(c) maintaining the web in feeding alignment between the pin cylinder and the pressure roller such that uniform sized microholes are perforated in the web area between the profile members.
摘要:
A reclosable plastic bag including grip strips of a plurality of spaced apart ridges extending generally parallel to one another over the width of the bag on opposed lips of the bag, wherein the ridges are characterized in cross-section by a lower generally triangularly-shaped portion and by an upper bulbous portion defined generally at an apex of the lower generally triangularly-shaped portion.
摘要:
An apparatus and method for measuring the tactility of a zipper of a reclosable thermoplastic zippered bag of the type described in commonly-assigned U.S. Pat. No. 5,070,584, including an opposed pair of mechanical fingers defining a gap therebetween through which the zipper is made to pass, means associated with the opposed pair of mechanical fingers for continuously measuring the resistance of the male and female profiles to being interlocked by such fingers as the zipper passes through the gap defined between such fingers, and means for recording, graphing, displaying and/or analyzing these measurements.
