Abstract: The invention comprises a blank for an envelope including a front panel, a rear panel and a closure panel, the closure panel being connectable in use to the front panel, the blank having two gluing areas by which the closure panel may be connected to the front panel in use. A removable strip is provided between the gluing areas, the removable strip being of sufficient dimensions to receive indicia associated with a first mailing thereon, at least some of which indicia are removed when the envelope is opened by removing the removable strip after the first mailing. The envelope may also have a second removable area. The removable strip may be wide enough to reveal a response indicia imprinted on the first panel.

Abstract: A multi-station dispensing apparatus which affords an automatic flow rate for the product to be dispensed. It also provides a single control knob which can select from several different chemical concentrates to be diluted and dispensed. In addition, a bottle can be filled by single-handed operation as well as a bucket without the need to reset the control knob.

Abstract: A mailing envelope comprising a sleeve with an opening at open end and a closed end, a closure associated with the opening at the open end, an envelope fold line intermediate the open end and the closed end when the envelope is in a flat configuration and one or more adhesive areas for at least partially maintaining the envelope in a folded configuration. Also, a method for packaging one or more sheets and/or components in the envelope.

Abstract: Audio or sound envelopes contain or are combined with a sound module for generating and playing prerecorded sound tracks upon the opening of the envelope or removal of its contents. Operation of the sound module may be activated by the opening of the envelope flap, or by removal of the envelope contents. The flap is configured with a removable strip which protects the sound module from damage before and after opening. The sound module can be replayed by repeated operation of the flap. Alternate embodiments of the audio envelopes have other structural or operational features which work in concert with the sound module.

Abstract: A combination closure tape and tear strip, an object comprising the combination closure tape and tear strip, and a method of sealing and later opening said object utilizing the combination closure tape and tear strip are disclosed.

Abstract: An envelope pull opener includes a pair of pull tabs and a tearing filament. A single pull tab is attached to each end of the tearing filament. A peel-off adhesive surface is applied to one side of the pull tab. Preferably, the other side of the pull tab is structured to have a logo, picture, or other graphical representation applied thereto. The pull tab is preferably round, but could be any other shape such as square or triangular. In a second embodiment, the pull tab opener has a single pull tab on each end and an anchor tab attached in substantially the middle of the tearing filament. A third embodiment includes, a rigid envelope pull opener includes a first arm, a second arm, a pivotal connector, and a pair of pull tabs. A single pull tab is attached to an end of each arm. The other end of each arm is pivotal constrained by the pivotal connector.

Abstract: A tear string envelope with the envelope made of an integral blank of sheet material and formed such that the front and rear portion of the envelope is interconnected by side flaps folded inwardly so that side edges and a lower and an upper folding edge are formed under leaving an upper insertion opening which can be closed by a gummed closing flap. The tear string extends at the inner side of an edge, with the tear string adhered at an edge different from that of the closing flap.

Abstract: An envelope blank, die cut from a sheet of flat paper stock, has a quadrilateral panel, a sealing flap, side flaps and a closure flap, with one of the side flaps having a slot formed therein to define a surmounting tab. A length of string is adhered to a fold obtaining between the panel and one of the side flaps, and lengthwise of the fold, and has a terminal end of the string adhered to the tab. With the tab externalized, the blank-formed envelope can be quickly and efficiently opened by pulling the tab away, and drawing the confined string out of the fold, whereby an end of the envelope is opened.
