Definitions

  • the present invention relates to containers, and particularly to containers for supplying beverages to consumers.
  • the invention has particular utility for the storage and supply of carbonated and other sparkling drinks, but is also suitable for use with non-carbonated drinks and other types of beverage or other materials.
  • a well known drink container comprises a glass bottle with a crown cap formed of metal.
  • the cap is pressed over a lip around the opening of the bottle and held in place by being crimped beneath the lip. Whilst very successful, this form of closure has the disadvantage that it requires a tool, e.g. a bottle opener, to prize the cap off the bottle.
  • container comprise a plastic bottle with a plastic screw cap.
  • these caps can be installed by pressing onto the bottle (rather than being screwed on) but their removal requires the cap to be unscrewed, often requiring rotation of the cap through 360 degrees or more.
  • This type of closure also requires the provision of thread forms on the exterior of the bottle neck.
  • the present invention seeks to provide an alternative to this prior art.
  • a container comprising a container body with an opening defining an axis passing therethrough and a cap having an upper portion and a skirt portion depending therefrom for closing the opening, the container body having an outwardly projecting lip around the opening, the cap having a plurality of spaced apart inwardly projecting members around an inner circumference of the skirt portion and the lip having a plurality of spaced apart recesses in a lower part thereof for receiving said members when the cap is press fitted to the container, the cap being arranged such that the circumference thereof is distorted into a substantially polygonal shape as portions thereof carrying said members are flexed outwards when the cap is initially pressed over the lip until the members snap fit into respective recesses in the lip, the members and recesses being shaped such that subsequent rotation of the cap relative to the container body tightens the cap against the lip.
  • a container comprising a container body with an opening defining an axis passing therethrough and a cap having an upper portion and a skirt portion depending therefrom for closing the opening, the container body having an outwardly projecting lip around the opening, the cap having a plurality of spaced apart inwardly projecting members around an inner circumference of the skirt portion and the lip having a plurality of spaced apart recesses in a lower part thereof for receiving said members when the cap is press fitted to the container body, the cap and recesses being shaped such that upon subsequent rotation of the cap relative to the container body in a loosening direction the circumference of the skirt portion is flexed into a substantially polygonal shape as the members are driven out of the respective recesses onto an external surface of the lip until the cap is free to be moved to an open position.
  • a container body for use in providing such a container and a cap for use in providing such a container.
  • One of the aims of the invention is to provide a container which has the aesthetics of a crown cap and the convenience of a screw cap.
  • Another aim is to provide a plastics cap which uses less material and hence is lighter than a conventional plastics screw cap.
  • FIGS. 1A and 1B show side views of a container according to a first embodiment of the invention with a cap shown fitted to a container body and shown detached from the container body;
  • FIG. 2 is an enlarged view of part of FIG. 1A ;
  • FIG. 3 is a perspective view of the container shown in FIG. 2 ;
  • FIGS. 4 to 7 show perspective views of a second embodiment of a container according to the present invention:
  • FIG. 4 shows a cap and container body prior to the cap being fitted thereto
  • FIG. 5 illustrates how the cap is fitted to the container body
  • FIGS. 6 and 7 illustrate how the cap is removed from the container body
  • FIG. 8 shows a cap and container body following removal of the cap from the container body.
  • FIGS. 9-13 show perspective views of a third embodiment of a container according to the present invention:
  • FIG. 9 shows a cap and container body prior to the cap being fitted thereto
  • FIG. 10 shows an underside view of the cap
  • FIG. 11 illustrates how the cap is fitted to the container body
  • FIG. 12 illustrates how the cap is opened
  • FIG. 13 illustrates how the cap may be re-fitted to the container body
  • FIGS. 14-18 show perspective views of a fourth embodiment of a container according to the present invention.
  • FIG. 14 shows a cap and container body prior to the cap being fitted thereof
  • FIG. 15 shows the cap when fitted to the container body
  • FIG. 16 shows the cap at a first stage of removal from the container body
  • FIG. 17 shows the cap at a second stage of removal from the container body
  • FIG. 18 shows the cap following removal from the container body.
  • FIGS. 19-21 show perspective views of a fifth embodiment of a container according to the present invention.
  • FIG. 19 shows a cap and container body prior to the cap being fitted thereof
  • FIG. 20 shows the cap when fitted to the container body
  • FIG. 21 shows the cap following removal from the container body.
  • FIGS. 1A and 1B show a container in the form of a bottle comprising a container body 1 and a cap 2 for closing an opening 3 at the upper end of the container body.
  • the opening may, typically, have a diameter of around 28 mm.
  • FIG. 2 shows an enlarged view of the neck portion of the container body 1 and of the closure cap 2 for fitting to the container body 1 .
  • the opening 3 at the upper end of the container body defines an axis A passing therethrough.
  • the container body 1 has an externally projecting lip 4 around the opening 3 .
  • a plurality (four in the illustrated embodiment) of spaced apart recesses 5 are provided in a lower part of the lip 4 .
  • Each of these recesses 5 is defined by an upper surface 5 A and two end surfaces 5 B and 5 C.
  • the upper part 4 A of the lip 4 has a smooth, curved profile such that its external diameter decreases at position towards an upper surface 4 B of the lip 4 .
  • the cap 2 comprises an upper portion 6 which a substantially circular skirt portion 7 depending therefrom.
  • a plurality (four in the illustrated embodiment) of spaced apart inwardly projecting members 8 are provided around the inner circumference of the skirt portion 7 . As will be described below, the members 8 engage with respective recesses 5 when the cap 2 is fitted to the container body 1 .
  • the cap 2 In order to install the cap 2 onto the container body 1 , it is pressed onto the lip 4 so that the members 8 engage the upper surface 4 B or curved surface 4 A thereof. As the cap 2 is pressed downwards, the members 8 slide over the curved surface 4 A and are thus driven radially outwards to ride over this surface until they reach the lower part of the lip and snap-fit into the respective recesses 5 .
  • the cap 2 is distorted into a substantially polygonal shape (a four-sided shape with rounded corners in the illustrated embodiment). This is possible due to the length of the circumferential spaces between adjacent members 8 and the resilient nature of the skirt portion 7 .
  • the inner surface of the skirt portion 7 in the areas between the members 8 is inclined outwardly towards the open end of the cap 2 so that the diameter of the opening in the cap increases towards the open end thereof. This also reduces the wall thickness of the skirt portion 7 towards the open end of the cap 2 so increasing the resilient flexibility of the cap in this region. Inclination of the inner surface also helps ensure a snug fit between the inner surface of the skirt portion 7 and the inwardly tapering external surface of the upper part 4 A of the lip when the cap 2 has been fitted to the container body 1 .
  • the spacing between the members 8 helps the skirt portion 7 of the cap to be capable of being flexed into a polygonal shape.
  • the length of each member 8 in the circumferential direction is less than the circumferential spacing between adjacent members.
  • the cap has an internal diameter of around 28 mm
  • each member 8 has a circumferential length of around 7-8 mm (at their largest dimension) and the circumferential spacing between adjacent members is around 13-14 mm.
  • the depth of the skirt portion 7 is typically 5-6 mm (compared to around 10 mm for a conventional 28 mm diameter screw cap).
  • Each of the members 8 has an upper surface 8 A, a lower surface 8 B, end surfaces 8 C and 8 D and an inwardly facing surface 8 E.
  • the lower surface 8 B is inclined upwardly in a radial direction, i.e. it slopes upwardly towards the axis of the cap, so that when the lid is pressed onto the container body the lower surface 8 B engages the curved surface 4 A of the lip whereby the members 8 are pushed radially outwards as they ride over the surface 4 A towards the lower portion of the lip 4 .
  • the lower surface 8 B is substantially horizontal.
  • the members 8 are able to ride over the external surface of the lip 4 as the skirt portion is flexed into a substantially polygonal shape until they reach the recesses 5 .
  • the members 8 then snap-fit into the recesses 5 as the resilience of skirt portion 7 brings it back to a substantially circular shape and the members 8 move radially inwards beneath the upper surfaces 5 A of the recesses 5 .
  • the upper surface 8 A of the members are then in engagement with the upper surfaces 5 A of the recesses.
  • the upper surface 5 A of the recesses is inclined in the circumferential direction so that if the cap 2 is then rotated in a tightening direction (clockwise when viewed from above in the illustrated embodiment) relative to the container body 1 , the cap 2 is tightened onto the container body 1 .
  • This causes the inner surface of the upper portion 6 of the cap and/or the inner surface of the skirt portion 7 thereof to be brought into sealing engagement with the surfaces 4 A and/or 4 B of the lip 4 .
  • the upper surfaces 8 A of the members 8 B are substantially horizontal in the radial direction but are inclined in the circumferential direction to add to the above tightening.
  • the end surfaces 5 B of the recesses 5 provide a stop to prevent the cap 2 being over-tightened. Engagement of the end surface 8 D of each projection with the end surface 5 B of the respective recess prevents further movement of the cap 2 in the tightening direction relative to the container body 1 .
  • the end surfaces 8 D and 5 B are both substantially vertical and both extend substantially radially towards the axis A.
  • the cap 2 To release the cap 2 it is rotated in the loosening direction (anticlockwise when viewed from above in the illustrated embodiment) relative to the container body. Initially, this moves each member 8 along the respective recesses from the end 5 B towards the end 5 C. Due to the inclination of the upper surface 5 A of the recess and/or of the upper surface 8 A of the member 8 , this permits the cap to move at least a short distance (e.g. 1-2 mm) in the direction of axis A away from the container body 2 . This releases the seal between the cap 2 and the container body and permits venting of the container body whereby excess pressure therein (for instance due to a carbonated beverage) may be released. The cap 2 is, however, still held captive on the container body 1 by the engagement of the members 8 in the recesses 5 so the cap 2 cannot fly off the container body 1 as this pressure is released.
  • a short distance e.g. 1-2 mm
  • each member Upon further rotation of the cap 2 in the loosening direction, the end surface 8 C of each member engages the end surface 5 C of the respective recess. These surfaces are both substantially vertical but are inclined so that as the cap 2 is rotated, the members 8 ride up the end surfaces 5 C whereby the members 8 are driven radially outwards (resulting in the skirt portion 7 again becoming substantially polygonal in shape) until they reach the external surface of the lip 4 in the region 4 C between adjacent recesses 5 .
  • the external surface of the lip 4 is inclined so that the diameter of the lip 4 reduces towards the open end of the container body 1 .
  • the skirt portion 7 of the cap tries to revert to a substantially circular shape so there is a tendency for the members 5 to slide upwards over the external surface of the lip 4 so they can move radially inwards in order for the skirt portion 7 to assume a more circular shape.
  • the cap 2 thus tends to ride up the lip 4 so it moves further in the direction of axis A away from the container body 1 . This also helps reduce the risk that the members 8 inadvertently slip back (clockwise) to re-engage the recess 5 or slip forwards (anticlockwise) to engage the next recess 5 .
  • each member 8 thus has a lower surface 8 B which is inclined upwardly in a radial direction but is substantially horizontal in a circumferential direction, an upper surface 8 A which is substantially horizontal in a radial direction but is inclined in a circumferential direction and two end surfaces 8 C, 8 D one of which is laterally inclined in a radial direction and both of which are substantially vertical in an axial direction.
  • These four surfaces define the perimeter of an inwardly facing surface 8 E which, as shown in FIG. 3 , is substantially triangular. In use, the surfaces 8 E lie adjacent the external surface of the container 1 within the recesses 5 .
  • FIGS. 4-8 illustrate a container according to a second embodiment of the invention. This is similar to the container shown in FIGS. 1-3 but also has a first type of tamper evident feature. Parts of the container of FIGS. 4-8 which correspond to those of the container of FIGS. 1-3 are given the same reference numeral but increased by 10.
  • the cap 12 is similar to the cap 2 but has a tamper band 10 depending from the skirt portion 17 thereof.
  • the tamper band 10 is connected to the skirt portion 17 by a plurality (sixteen in the illustrated example) of small, friable bridges 10 A and a plurality (four in the illustrated example) of tether bands 10 B.
  • a plurality (four in the illustrated example) of projections 10 C project radially inwards from the inner surface of the tamper band 10 .
  • the skirt portion 17 is flexed into a substantially polygonal shape as the members 18 ride over the lip 14 until they engage recesses 15 as in the first embodiment.
  • the projections 10 C ride over the lip 14 when the cap 12 is pressed onto the container body 11 and, once the cap 12 has been rotated in the direction D 2 shown in FIG. 5 , the projections 10 C are located beneath lower surfaces 14 D of the portions 14 C of the lip 14 between the recesses 15 .
  • the lower surfaces 14 D of the lip 14 are inclined in the circumferential direction so that when the cap 12 is rotated in the direction D 3 (the loosening direction) as shown in FIG. 6 , the projections 10 C are driven downwards as illustrated by arrow D 4 in FIG. 6 . As the remainder of the cap 12 is unable to move downwards (as it is engaged on the upper surface of the lip 14 ), this causes rupture of the friable bridges 10 A (as shown in FIGS. 6 and 7 ).
  • the projections 10 C are positioned on the band 10 so that once the members 18 have moved along the recesses 15 to engage the end surfaces 15 C thereof and ride up these onto the external surface of lip 14 (flexing the skirt portion 27 into a substantially polygonal shape), the projections 10 C have moved along the lower surfaces 14 D to the adjacent recess 15 .
  • the cap 12 is then free to be removed in the direction D 5 (with the tamper band 10 connected thereto by the tether bands 10 B) as shown in FIG. 7 and detached from the container body 11 as shown in FIG. 8 .

  • the members 28 ride up the end surfaces 25 C of the recesses 25 (flexing the skirt portion 27 into a substantially polygonal shape) so the upper portion 26 and skirt portion 27 are able to move upwards as in the first embodiment but the tamper band 20 is prevented from doing so by the engagement of the edge 20 E of portion 20 D under the lower surfaces 24 D of the lip 24 .
  • This causes rupture of the friable bridges 20 A although the tamper band 20 remain connected to the remainder of the cap 22 by the tether band 20 B.

  • FIGS. 19-21 illustrate a container according to a fifth embodiment of the invention. This is similar to the container shown in FIGS. 1-3 but also has a fourth type of tamper evident feature. Parts of the container of FIGS. 19-21 which correspond to those of the containers of FIG. 1-3 are given the same reference numeral but increased by 40.
  • the cap 42 is similar to the cap 2 but has a tamper band 40 depending from the skirt portion 47 thereof.
  • the tamper band 20 is connected to the skirt portion 27 by a plurality (eight in the illustrated example) of small, friable bridges 40 A.
  • a plurality (four in the illustrated example) of projections 40 C project radially inwards from the inner surface of the tamper band 40 .
  • the container body 41 is similar to that of the first embodiment but in addition has a plurality (two in the illustrated example) of projections 41 A which project radially outward from the exterior wall of the body 41 at positions below and spaced from the outwardly projecting lip 44 (see FIGS. 19 and 21 ).
  • a groove 41 B is provided in the container wall for gripping by a blow moulding tool. This groove divides each projection 41 A into two parts.
  • the skirt portion 47 is flexed into a substantially polygonal shape as inwardly projecting members 48 (now shown) ride over the lip 44 until they engage recesses 45 as in the first embodiment.
  • the projections 40 C ride over the lip 44 when the cap 42 is pressed onto the container body 41 and, once the cap 42 has been rotated in the tightening direction, the projections 40 C are located at the level of the projections 41 A referred to above.
  • the projections 40 C on the cap 42 engage the projections 41 A on the container body 41 so as to halt rotation of the tamper band 40 relative to the container body 41 . Further rotation of the cap 42 in the loosening direction thus causes rupture of the friable bridges 40 A as well as moving members 48 (not shown) of the cap 42 out of the recesses 45 in the lip 44 of the container body 41 . The cap 42 is then free to be removed from the container body 41 .
  • the tamper band 40 is separated from the cap 42 upon rupture of the friable bridges 40 A and drops down the neck of the container 41 as shown in FIG. 21 to a position at which the external diameter of the container 41 is similar to the internal diameter of the band 40 .
  • the band 40 may be lifted off the neck of the container 41 separately from the cap 42 .
  • the cap may be formed of a plastics material, e.g. by injection moulding.
  • the container body may also be formed of a plastics material, e.g. by injection moulding and blow moulding.
  • the container body may, however, also be made of glass.
  • the diameter of the opening of the container body preferably lies in the range 25-30 mm, e.g. as typically used for bottles. However, the invention may also be used on containers with other size openings, including diameters up to 50 mm and wide mouth openings (which typically have a diameter in the range 50-80 mm).
  • the cap is provided with four internally projecting members for engaging four recesses in the lip of the container body.
  • Other embodiments may use more or less members and recesses.
  • Preferred embodiments have three, four or five members and recesses.
  • Four members (and recesses) may, for example, be used for a container opening with a diameter in the range 25-35 mm, five for a container with an opening in the range 35-45 mm and six for an opening in the range 45-55 mm. More members (and recesses) may be used for a given diameter but the greater the number the less flexible the skirt of the cap will be (although, with a large number of members each need project inwards by a smaller distance).
  • the container employs two separate camming actions to distort the skirt portion of the cap into a substantially polygonal shape, one when the cap is fitted to the container body and the other when the cap is removed therefrom.
  • the inwardly projecting members on the cap are forced radially outwards over the lip as the cap is press-fitted to the container body.
  • the members are forced radially outwards by ramps at the ends of recesses in the lip as the cap is rotated relative to the container body.
  • Containers having the features described above can thus be press-fitted to a container body and can be opened by a relatively small rotational movement (depending on the number of projecting members used). With four members, the cap need be rotated less than 90 degrees to release it from the container body. In addition, no external threads need be provided on the neck of the container body. The neck may therefore have a smooth aesthetically pleasing appearance, e.g. as on a conventional glass bottle neck.
  • the cap which is preferably formed of a plastic material, can thus be press-fitted to the container, the container need not have thread portions on the exterior of the neck and the cap can be removed by a relatively small rotational movement.
  • the cap may be arranged so it can be re-fitted by a user.
  • the cap thus combines the advantages of a conventional crown closure and a conventional screw-threaded cap and bottle neck. It also uses significantly less material than a conventional plastic screw cap so saves on material cost and weight.
