Publication number: 20090314780Abstract: An all plastic container comprising the combination of injection molded pail and lid. The lid initially locks onto the container at upper and lower undercuts and seals thereto by virtue of an inverted U-shaped peripheral section. A tear line is formed in the lid skirt to facilitate removal of the lower lock. The upper lock is segmented so as to make removal of the lid easier once the lower lock is removed. Indicia on the lid shows where the gaps in the lock segments are located. The lower lock may also be segmented to provide drainage for overfill which comes out of the pail when the lid is first applied.Type: ApplicationFiled: September 2, 2009Publication date: December 24, 2009Applicant: LETICA CORPORATIONInventors: John Robert SELINA, Arthur HABITZ

Patent number: 7631776Abstract: A container clearly indicates that it has been opened after a store clerk loads food into the base of the container and closes a covering of the container onto the base. The covering (16) includes a peripheral cover portion (22) that becomes fixed to a peripheral base portion (32) when the clerk initially closes the container. To thereafter open the container, a person forcefully lifts a tab (30) on the covering to tear the covering along a long tear line (26) that separates the peripheral cover portion (22) from a lid (24) formed by a radially inner covering portion. The base (12) is fixed to the peripheral covering portion (22), and together they form a base device (40). After the lid has been torn free of the peripheral covering portion, the lid can be closed and latched to the base device and then can be easily opened again.Type: GrantFiled: June 5, 2006Date of Patent: December 15, 2009Assignee: PWP IndustriesInventors: Terry Vovan, Jose Enriquez

Patent number: 7628283Abstract: A tamper-indicating child-resistant package includes a container having a cylindrical finish with at least one external thread segment, a manually deflectable release element externally cantilevered from the finish, and a tear band frangibly connected to the finish and having an upstanding locking lug. A closure has a skirt with at least one internal thread segment for mating engagement with the external thread segment on the container finish, a first lock element on the skirt for engagement with the manually deflectable release element and second lock element on the skirt for engagement with the locking lug on the tear band. Engagement between the second lock element on the closure skirt and the locking lug on the tear band prevents unthreading of the closure from the container finish until the tear band is frangibly removed from the finish, whereupon deflection of the manually deflectable release element releases the closure for unthreading from the finish.Type: GrantFiled: January 16, 2007Date of Patent: December 8, 2009Assignee: Rexam Prescription Products Inc.Inventor: John M.

Publication number: 20090277861Abstract: The present invention relates generally to a closure for a container, such as a bottle or the like, and more particularly, to a resealable, tamper evident closure for a container. The closure consists of a top section connected to a lower skirt portion. The closure is structured such that it would be evident if one were to attempt to remove the closure or tamper with the closure and that the contents of the container should not be consumed due to the risk of possible contamination.Type: ApplicationFiled: May 8, 2008Publication date: November 12, 2009Inventor: CHARLES J. LONG, JR.

Publication number: 20090272745Abstract: A disposable substance dispensing apparatus comprises a plurality of disposable substance dispensing containers coupled together in the shape of a fruit. Each of the containers is in the shape of a slice of fruit and has a fillable chamber accessed by a port through one of the outer walls of the container. A packaging material extends around each of the containers to hold the dispensing apparatus in the shape of a fruit. Each of the containers may individually be removed from the apparatus. The port of each container may be accessed by a single use tear-off or twist-off impermeable cap.Type: ApplicationFiled: May 2, 2008Publication date: November 5, 2009Inventors: Ryan Dohse, Brian Taggart

Patent number: 7608032Abstract: A tamper evident and resistant container lid of the present invention includes a lid body configured to cover the opening of a base container having a top rim and a skirt extending from the lid. The skirt has an annular score line and an annular fold line extending therearound. An outer band of the skirt extends between the score line and the fold line, and an inner band folded inwardly to be in opposing relation to the outer band extends upwardly from the fold line to an upper free edge. When the container lid is sufficiently applied to the base container such that the second portion slides downwardly past a top rim of the base container, achieving a proper closure, an attempt to remove the lid will cause a plurality of sections of the inner band to engage the top rim and impede removal of the container lid from the base container.Type: GrantFiled: September 16, 2008Date of Patent: October 27, 2009Assignee: Huhtamaki Consumer Packaging, Inc.Inventors: Ronald Dean Robertson, George Edward Mac Ewen

Publication number: 20090230129Abstract: The invention relates to a tear-open seal packaging (10), with a packaging element (12) having an opening (30) and a tear-open film (14), which closes opening (30) and is connected along its outer edge portion (16) with the opening edge (32) of packaging element (12) by a sealing seam (18). Sealing seam (18) has at least one indentation (26,28) which extends inwards from the outer edge of sealing seam (18), and whose depth of extension is less than width (B) of sealing seam (18) at the point of the indentation (26,28).Type: ApplicationFiled: August 20, 2008Publication date: September 17, 2009Applicant: Rainer Naroska Engineering GmbHInventor: Rainer Naroska

Patent number: 7568585Abstract: A unitary capseal for a closure that is installed in a container includes an annular sidewall, a generally circular top panel joined to the sidewall, a snap-on annular rim formed adjacent a lower edge of the sidewall, and an annular sealing lip formed adjacent the annular rim. The cooperating closure includes a serrated flange, a closing plug for threaded receipt by the flange, and a sealing gasket positioned therewith. The container end is formed around the flange interlocking with the flange serrations and creating an outer annular channel that receives the annular rim for a snap-on assembly of the capseal to the container end that in turn positions the capseal over and around the closure. The sealing lip extends radially outwardly from the sidewall and includes a concave surface facing the container end for sealing off the interior portions of the closure from collecting debris.Type: GrantFiled: November 16, 2004Date of Patent: August 4, 2009Assignee: Rieke CorporationInventors: Gary M. Baughman, Robert D. Rohr

Patent number: 7537132Abstract: A plastic integrally molded single use sealing plug for permanently closing off the center fill opening in metal lids surrounded by an upstanding neck having an inward curl terminating in a free edge. The sealing plug has a circular top wall and a depending cylindrical sidewall which makes at tight friction fit with the neck free edge. A peripheral tamper evident ring is connected to the plug sidewall by a series of frangible connecting webs.Type: GrantFiled: August 20, 2004Date of Patent: May 26, 2009Assignee: American Flange & Mfg.

Publication number: 20090026203Abstract: An all plastic container comprising the combination of injection molded pail and lid. The lid initially locks onto the container at upper and lower locations and seals thereto by virtue of an inverted U-shaped peripheral section with a segmented upper lock and a relatively continuously lower lock at the bottom edge of the lid skirt. The bottom lock can be torn away by way of a circumferentially weakened area that forms the lower edge of the skirt into a tear band. A starter tab is provided. Once the tear band is removed the segmented upper locks securely hold the lid to the pail. However, by lifting and flexing the lid at discrete locations identified by indicia on the top deck of the lid, the lid is relatively easily removed.Type: ApplicationFiled: July 23, 2007Publication date: January 29, 2009Applicant: Letica CorporationInventors: John Robert Selina, Arthur Habitz
