Patent number: 11066221Abstract: A package and method for opening the package are disclosed. The package includes a first film and a second film forming an enclosure and at least one tab area and defining a package periphery, the enclosure defining an interior volume configured to receive a product. The package further includes first and second breachable bubbles formed within first and second tab portions of the at least one tab area. Upon application of pressure by a user, the first and second breachable bubbles breach. The package may be alternated between a first position, wherein the first tab portion and the second tab portion are substantially sealed from each other to facilitate breaching, and a second position, wherein the first tab portion and the second tab portion are in fluid communication with each other.Type: GrantFiled: January 11, 2019Date of Patent: July 20, 2021Assignee: PopPack LLCInventors: William S.

Patent number: 10836518Abstract: A rigid holding container has a flexible cover sheet extending over the holding area for sealing the contents. The container has a wide, flat perimeter lip which provides a firm base for the seal between the cover sheet and the container. A breaching bubble is formed in the seal, under the cover and over the perimeter lip. The consumer breaches the bubble by pressing the bubble against the lip between the thumb and forefinger. The pressure compresses the air in the bubble causing the bubble to expand laterally. The expanding bubble breaches along the perimeter of the lip, producing a peel flap of flexible cover material. The consumer pulls the peel flap while holding the rigid container down, to remove the cover sheet.Type: GrantFiled: January 31, 2019Date of Patent: November 17, 2020Assignee: PopPack, LLCInventors: William S. Perell, Leif B. Sorensen

Patent number: 9802745Abstract: A container for dispensing various compositions includes a pourable spout located within a breachable bubble. In one embodiment, for instance, the container can be made from flexible polymer films. The container can include a sealed perimeter that defines an opening where a pourable spout is located. A locking bubble can be located over the opening for preventing liquids from being dispensed from the container prior to opening the bubble. When it is desired to dispense the container, the bubble can be breached which therefore allows the contents of the container to be dispensed through the opening.Type: GrantFiled: September 2, 2008Date of Patent: October 31, 2017Assignee: Poppack LLCInventors: William S.

Publication number: 20100278462Abstract: An easy to open package is described. The package includes a sealed compartment having a tab region. The tab region is formed by connecting together a first panel to a second panel. Within the tab region, however, are a pair of opposing peel tabs. The peel tabs comprise an area within the tab region where the first panel is not sealed to the second panel. The peel tabs extend from the tab region to an edge of the package. In this manner, a user can peel apart the peel tabs to separate the first panel from the second panel and open the sealed compartment. In one embodiment, at least one of the peel tabs can be coated with a material to prevent the first panel from sealing to the second panel.Type: ApplicationFiled: May 1, 2009Publication date: November 4, 2010Applicant: POPPACK, LLCInventor: Leif B.

Patent number: 5895587Abstract: An improved food package comprises a cook-in film encasing an in situ aqueous medium cooked meat product. The film has a polymeric olefin containing inner surface in adhering relation to the cooked meat product. The film inner surface is treated by a cold plasma in a confined region which has been evacuated to a pressure less than atmospheric pressure and to which a selected process gas other than air and containing less than 30% nitrogen has been added which results in a gas plasma that reacts with a film surface during cold plasma treatment to increase the surface energy of the film to more than 44 dynes/cm and provide a film that is both heat sealable to the package with an acceptable bond strength for sealing the package, and capable of adhering in a uniform and well controlled manner to the cooked meat product during cook-in without purge.Type: GrantFiled: January 21, 1997Date of Patent: April 20, 1999Assignee: Cryovac, Inc.Inventor: Leif B.

Patent number: 5188461Abstract: A packing comprising first and second opposed surfaces in a closure area of the packing has profiled portions secured to and extending over each of the opposed surfaces, which profiled portions are adapted to be releasably interengaged to permit connection and disconnection of the opposed surfaces. The profiled portions are each formed integrally with an outer layer of a strip material secured to the associated one of the opposed surfaces. The outer layer of the strip material is formed of a material well suited for forming a peel seal weld with the other opposed surface of the packing, such as a portion of the outer layer of the opposing strip material. The outer layer of each strip material is secured to the one of the first and second opposed surfaces via a base layer of the strip material to which the outer layer is secured by means of a non-peel seal type connection. As a result, the sheete material of the packing, a bag for example, need not be formed of a peel seal weldable material.Type: GrantFiled: March 2, 1992Date of Patent: February 23, 1993Assignee: Schurpack, Inc.Inventor: Leif B.
