Definitions
- This invention relates to containers and resealable closures. More particularly although not exclusively an improved plastic container and radial seal closure is disclosed.
- the invention discloses a resealable closure for plastic containers of a type having a mouth formed with an inner circular neck bore and spaced apart neck stubs arranged around the outside thereof, said closure in one position of use having a top panel, a peripheral downwardly extending skirt with inwardly directed locking lugs and an inner spigot seal dimensioned for an interference fit into said neck bore whereby said closure is adapted to removably seal said container by push fitting the spigot seal into engagement with said neck bore and subsequently locking the closure by rotation to a position where the lugs align under said neck stubs.
- the container and closure are moulded from a resiliently deformable plastic.
- neck stubs and locking lugs are dimensioned and positioned to cause distortion upon locking the closure whereby frictional resistance holds said closure at the locked position.
- the underside faces of said neck stubs are substantially flat to evenly engage the locking lugs.
- outside surfaces of the container and closure are shaped, textured or otherwise marked in a manner to provide a visual or tactile indication of a locked or unlocked configuration of said closure.
- said closure is adapted to move in either rotational direction between the locked and unlocked positions.
- figure 1 is an elevation view of a resealable closure in accordance with a first embodiment of said invention
- figure 2 is a cross-sectional view along the lines A-A of figure 1
- figure 3 is a vertical cross-sectional view through the centre of the closure of figure 1
- figure 4 is an elevation view of a container according to said invention
- figure 5 is a plan view of the container neck
- figure 6 is a horizontal cross-sectional view through the container and fitted closure when in the unlocked position
- figure 7 is a vertical elevation view of the closure when fitted to the container in the locked position
- figure 8 is a view similar to figure 6 but with the closure in the locked position
- figure 9 is an elevation view of the closure fitted to the container in the locked position
- figure 10 is a plan view of a resealable closure in accordance with a second embodiment of the invention
- figure 1 1 is a cross-sectional elevation view of the resealable closure of figure 10
- figure 12 is a cross-sectional elevation view
- the closure may comprise a flat upper panel 1 with side panels 2 which are formed into a hexagonal Iy shaped skirt. As best shown in figure 2 the inside walls of the side panels have inwardly protruding locking lugs 3. The inside surface of the upper panel 1 is also formed with a central spigot seal 4. This seal is shaped and dimensioned for an interference sealing fit with a container 5 as discussed in more detail hereunder.
- the container as shown in figures 4 and 5 may also be hexagonally shaped with outer wall panels 6 to match the profile of the closure.
- the upper end of the container is formed into a neck 7 with an annular inner bore 8.
- the neck is formed around the outside with stubs 9 which have underside locating flats 10. These stubs are positioned for locking engagement with the aforementioned lugs 3 in the closure.
- the closure In use the closure is fitted to the container by placing it over the neck with the locking lugs 3 and neck stubs 9 initially offset to clear each other as shown in figure 6. The spigot seal is then pushed into the neck bore 8 to the position shown in figure 7. To complete the assembly the closure is subsequently locked in place by rotating it on the container so that the locking lugs engage under the locating flats of the neck stubs 9 as shown in figure 8. The relative locations of these lugs and stubs are such that the closure panels are distorted during this engagement. This provides a degree of frictional resistance to releasably retain the closure at the locked position.
- the position of the lugs and stubs are preferably also arranged so that when engaged the outer surfaces of the panels 2 align with the container panels 6 as shown in figure 9 to provide a visual or tactile indication of the locked closure.
- Undercuts 10 may also be formed across the aligned panels 2 and 6 for labels or the like.
- the closure may comprise a flat upper panel 1 1 A with side panels 12 which are formed into a rectangular skirt.
- the inside walls have inwardly protruding locking lugs in the form of catch plates 13.
- the inside of die upper panel 1 1 is also formed with a central spigot seal 14. This seal is shaped and dimensioned for an interference sealing fit with the container 15 A as described in more detail hereunder.
- the container as shown in figures 12 to 14 is rectangular in shape to preferably match the profile of the closure.
- the upper end of the container is formed into a neck 16 with an annular inner bore 17.
- the neck is formed around the outside with protruding cam shaped stubs 18 which have underside engagement surfaces 19. These stubs 18 are positioned for locking engagement with the aforementioned catch plates 13 on the closure.
- Located under the lugs 18 is a square locating plate 20.
- closure of this second embodiment is fitted to the container 1 5A by placing it over the neck 16 with the catch plates 13 and cam lugs 18 initially offset to clear each other as shown in figure 1 5.
- the spigot seal 14 is then pushed into the neck bore 17 and the closure locked in place by rotating it to be in register with the container.
- the catch plates 13 engage under respective cam lugs 18 as shown in figure 16.
- the matching rectangular profiles of the closure and container preferably align at this position to show that they are in locking engagement.
- the shape and configuration of the closure, spigot seal and container may be changed from the designs shown.
- the closures may even be circular when used on paint drums for example.
- the invention is also not limited to any specific material for the closure or container although a readily mouldable and low cost plastic such as P.E.T. is currently preferred. This would provide good 02 resistance and with light tightening there would be no threads to bind up if the container is hot filled.
