Patent Application
20100044335
This invention relates to a drinking vessel that is also adapted to function as a closure for a drinks container, and to a drinks packaging product incorporating the drinking vessel.
The applicant of the present invention is also the applicant of the New Zealand patent application numbers 527195 and 538172, and has been involved in the development of packaging systems for single serve drinks for a number of years. The present invention relates to developments over the systems described in the above patent applications which address on going problems that have been experienced during the research and development process.
The problem has been to devise a tamper evident seal for use with a drink packaging product which includes both a bottle and a drinking vessel. Early attempts to solve this problem have involved the use of a paper or plastic wrap fitted over the join between the mouth of the drinking vessel and the body of the bottle.
However this type of seal has a number of problems. It involves the use of an additional item of material, and this additional item must be fitted by adding another step to the production line used to fill and seal the drink packages. This additional material and production step adds to the cost of producing each packaged drink.
Also, a tamper evident seal which is removed from the packaged drink when the package is opened is a problem. The person opening the drink has one hand to hold the bottle and one to hold the drinking vessel, and another item can be a nuisance and is likely to become a litter hazard. This problem can be significant in an airline situation where seated passengers are provided with drinks, and where a tear off seal is yet another object to handle and one that will often end up on the floor or under seat cushions etc.
In New Zealand patent application number 538172 a tamper evident seal was developed which was situated within the drinking vessel and which engaged with the neck of the bottle. However, it was found to be difficult to obtain a water tight seal at the join of the two part drinking vessel of that earlier design. At present it is also considered that the design could be improved upon to simplify manufacture or reduce manufacturing costs.
It is therefore an object of the present invention to provide a drinking vessel or a drinks packaging product which will at least go some way towards overcoming the above mentioned problems, or at least provide the public with a useful choice.

Further aspects of the present invention will become apparent from the following description which is given by way of example only and with reference to the accompanying drawings in which:
With reference to
Formed as an integral part of the base part (11) is a threaded bottle cap (17) which also includes a frangibly linked tamper evident ring (19). When assembled, the drinking vessel (10) forms a drinking vessel that can also be used as a closure of a drinks container, for example a drink bottle. The drinking vessel (10) can be screwed onto a bottle to close the bottle, and when removed from the bottle can be used as a drinking vessel.
In this example, the lower part (25) of the main vessel part (13) of the drinking vessel (10) is tapered to form a stem feature immediately above the base. The diameter of the stem feature is determined primarily by the outside diameter of the cap (17).
The sealing ring (15) can be formed as part of the base part (11) or the main vessel part (13), but from a material having different physical characteristics, for example from a material having a greater elasticity. The sealing ring (15) can be formed by an overmolding process, for example by overmolding the sealing ring (15) onto the surface of the base part (11) or into a groove about the circumference of the base part (11).
A suitable material for the sealing ring (15) is a thermoplastic elastomer (TPE) material.
The base part (11) and the main vessel part (13) can be joined using glue or welding, for example, ultrasonic welding. However in this example the base part (11) and the main vessel part (13) are joined by a mechanical, or interlocking, joint. Lugs (21) on the interior of the main vessel part (13) are configured to mate and lock into corresponding recesses (23) provided on the exterior of the base part (11). The use of a mechanical joint eliminates the need for an additional welding step during manufacture.
With reference to
Each of the three parts, the base part (31), the main vessel part (33) and the threaded cap part (35) can be made from a material selected to suit the function of that part. For example a suitable material for the main vessel part (33) is a rigid clear plastics material, for example a styrene plastics material, which provides a somewhat glass like appearance and feel. A softer and more elastic plastics material, e.g. polypropylene or polyethylene, can be used for the cap part (35) to facilitate the incorporation of a tamper evident seal (36) in the cap part (35). The tamper evident seal (36) must stretch over a mating ring about the neck of a bottle and shrink back toward their original size so that the seal will stay with the bottle when the cap part (35) is removed.
Preferably a mechanical joint is provided between the cap part (35) and the base part (31) and/or the main vessel part (33). In this example, a ridge (37) extends about the circumference of the cap part (35) and this ridge can be captured between an internal shoulder (39) on the main vessel part (33) and a rim (41) on the base part (31) when the two parts (31) and (33) are assembled together. In this way, the ridge (37) substantially prevents the cap part (35) from exiting the interior of the drinking vessel (30).
Preferably the mechanical joint between the cap part (35) and the base part (31) and/or the main vessel part (33) is configured to substantially prevent relative rotation between the cap part (35) and the base part (31) and/or the main vessel part (33). In this example, the cap part (35) is provided with a series or recesses (43) about the periphery of its lower surface (45) which are configured to mate with a series of protrusions (47) situated on the base part (31). When the drinking vessel (30) is assembled the protrusions (47) engage with the recesses (43) to substantially prevent relative rotation between the cap part (35) and the base part (31).
The base part (31) can be connected to the main vessel part (33) using glue,or by welding, for example using ultrasonic welding. The mating surfaces of the base part (31) and/or the main vessel part (33), where they can be connected, can be shaped to facilitate a weld, for example by making the lower surface (49) of the lower lip of the main vessel part (33) “V” shaped as shown.
This design allows the main vessel part (33) and the base part (31) to be manufactured from the same material, for example from a styrene plastics material, since neither part includes the tamper evident seal (36). And since both the main vessel part (33) and the base part (31) can be manufactured from the same material, they can be welded together.
Optionally the base part (31) can be connected to the main vessel part (33) by a suitable mechanical joint.
As with the previous example, in this example also, the lower part (51) of the main vessel part (33) of the drinking vessel (30) is tapered to form a stem feature immediately above the base. The diameter of the stem feature is determined primarily by the outside diameter of the cap (35).
With reference to
The sealing cap (63) includes an internal thread (65) and is configured to be a suitable closure device for a bottle having a mating thread about its opening. The sealing cap (63) can be provided with a tamper evident seal (66) to indicate whether the bottle has been opened after the cap (63) was initially installed. Preferably the main body (61) of the drinking vessel (60) is made of a clear material so that the state of the tamper evident seal can be viewed prior to removal of the drinking vessel (60) from the bottle.
A softer and more elastic plastics material, e.g. polypropylene or polyethylene, can be used for the sealing cap (63) since it includes the tamper evident seal (66). The tamper evident seal (66) must stretch over a mating ring about the neck of a bottle and shrink back toward its original size so that the seal will stay with the bottle when the cap (63) is removed.
The main body (61) of the drinking vessel (60) is configured to fit at least partially over the bottle to which it is fitted. Preferably the drinking vessel (60) is sized such that at least half of the contents of the drinks packaging product or bottle can be accommodated in the drinking vessel (60).
The main body (61) is adapted to receive and to retain the sealing cap (63) within, or adjacent to, a base portion (67) of the main body (61). A protruding lip (71) which can extend part way or all the way about the circumference of the cap (63), or similar protrusions, can be configured to mate with a corresponding groove (73) or recesses in the interior of the main body (61) to prevent the cap (63) exiting the main body (61) once installed. When the cap (63) is pushed into the inside of the main body (61) the lip (71) can engage with the groove (73) to substantially prevent the cap (63) exiting the main body (61). The cap (63) can be made from a plastics material and the elasticity of the material will allow it to compress slightly during installation. Preferably the protruding lip (71) is provided with a lead-in taper, as shown, to facilitate installation of the sealing cap (63) into the main body (61).
The cap (63) can also be provided with protrusions or recesses that are configured to mate with corresponding recesses or protrusions in the inside diameter of the main body (61) to prevent the cap (63) from rotating within the main body (61). This is important to enable the drinking vessel (60) to be removed from a bottle or other drinks packaging product. In this example the main body (61) is provided with a relatively fine internal spline form (75) which is configured to mate with a corresponding external spline form (77) about the outside diameter of the cap (63). When the cap (63) and the main body (61) are assembled the engaged spline forms substantially prevent relative rotation between the cap (63) and the main body (61). The use of fine spline forms is advantageous in that they are easily engaged when the cap (63) is inserted into the main body (61) without the need for careful alignment.
The base portion (67) of the drinking vessel (60) can be provided with a suitably configured and sized foot (69) upon which the drinking vessel (60) can stand upright in a stable manner. Preferably the diameter or width of the footprint of the foot (69) is similar to the diameter or width of the main body (61) of the drinking vessel (60).
The drinking vessel (60) can be a stemmed drinking vessel as shown, however in an alternative embodiment, the drinking vessel (60) can be a flat bottomed tumbler style drinking vessel having a short tubular shaped protruding portion connected to the interior of the base of the drinking vessel which is adapted to receive the sealing cap (63).
With reference to
The cap (83) comprises an internally threaded cylinder (87) which connects to a base (89) of the main body (81). The cap (83) formed by combining the cylinder (87) and a section of the base (89) can be used as a closure for a drinks packaging product or bottle. The tamper evident seal (85) is connected by a frangible link (86) to the other end of the threaded cylinder (87).
In this example, the drinking vessel (80) is a flat bottomed tumbler style of drinking vessel. However, it is envisaged that the drinking vessel (80) could also be a stemmed style of drinking vessel as shown and described herein in examples one to three and example five. An advantage of the flat bottomed tumbler style of drinking vessel is the space about the cap (83) which can be useful to facilitate the operation of a plastics injection molding tool if required to form the shapes of the frangible link (86).
Preferably at least the main body (81) of the drinking vessel (80) is made of a clear material to allow the state of the tamper evident seal to be inspected prior to removal of the drinking vessel (80) from a drinks packaging product or bottle. Since the drinking vessel (80) is a one piece vessel, and it includes a tamper evident seal (85), it would be preferable to make the vessel (80) from a plastics material having sufficient memory so that the seal (85) will shrink back to, or near, its original size after it is fitted over a protruding ring on the neck of a bottle. A suitable plastics material would be a polypropylene or a polyethylene plastics material.
Preferably the drinking vessel (80) is adapted to fit at least partially over a bottle, and preferably the drinking vessel (80) is sized such that at least half of the contents of the drinks packaging product or bottle can be accommodated in the drinking vessel (80).
With reference to
Preferably the drinking vessel further includes a sealing member (105) which is adapted to aid in sealing the opening of a drinks container to which the drinking vessel (100) can be fitted. The sealing member (105) can be a typical laminated seal, for example a laminated plastics and aluminium seal as is used in the drinks packaging industry.
An advantage of this design is that the sealing member (105) can be fitted prior to the threaded sleeve (103), making it simpler to install the sealing member (105) which will typically have an outside diameter that is greater than the inside diameter of the threads (107) of the threaded sleeve (103).
Preferably the threaded sleeve (103) further includes a frangibly linked tamper evident seal (108).
The main body (101) is adapted to receive and to retain the threaded sleeve (103) within, or adjacent to, a base portion (109) of the main body (101). A protruding lip (111) which can extend part way or all the way about the circumference of the threaded sleeve (103), or similar protrusions, can be configured to mate with a corresponding groove (113) or recesses in the interior of the main body (101) to prevent the threaded sleeve (103) exiting the main body (101) once installed. When the threaded sleeve (103) is pushed into the inside of the main body (101) the lip (111) can engage with the groove (113) to substantially prevent the threaded sleeve (103) exiting the main body (101). The threaded sleeve (103) can be made from a plastics material and the elasticity of the material will allow it to compress slightly during installation. Preferably the protruding lip (111) is provided with a lead-in taper to facilitate installation of the threaded sleeve (103) into the main body (101).
The threaded sleeve (103) can also be provided with protrusions or recesses that are configured to mate with corresponding recesses or protrusions in the inside diameter of the main body (101) to prevent the threaded sleeve (103) from rotating within the main body (101). This is important to enable the drinking vessel (100) to be removed from a bottle or other drinks packaging product. In this example the main body (101) is provided with a relatively fine internal spline form (115) which is configured to mate with a corresponding external spline form (117) about the outside diameter of the threaded sleeve (103). When the threaded sleeve (103) and the main body (101) are assembled the engaged spline forms substantially prevent relative rotation between the threaded sleeve (103) and the main body (101). The use of fine spline forms is advantageous in that they are easily engaged when the threaded sleeve (103) is inserted into the main body (101) without the need for careful alignment.
Preferably the drinking vessel (100) is adapted to fit at least partially over, and to provide a closure for, a bottle.
The main body (101) of the drinking vessel (100) can be made of a clear material and the threaded sleeve (103) can be made of an at least partially flexible material. Suitable materials are a clear styrene plastics material for the main body (101) and polypropylene or polyethylene plastics material for the threaded sleeve (103). A clear material is also advantageous for the main body (101) of the drinking vessel (100) since it allows the condition of the tamper evident seal (108) to be inspected.
A softer and more elastic plastics material, e.g. polypropylene or polyethylene, can be used for the threaded sleeve (103) since it includes the tamper evident seal (108). The tamper evident seal (108) must stretch over a mating ring about the neck of a bottle and shrink back toward their original size so that the seal (108) will stay with the bottle when the drinking vessel (100) complete with sleeve (103) is removed.
Preferably the drinking vessel (100) is sized such that at least half of the contents of the drinks packaging product or bottle can be accommodated in the drinking vessel (I 00). The base portion (107) of the drinking vessel (100) can be provided with a suitably configured and sized foot (119) upon which the drinking vessel (100) can stand upright in a stable manner. Preferably the diameter or width of the footprint of the foot (119) is similar to the diameter or width of the main body (101) of the drinking vessel (100).
The drinking vessel (100) can be a stemmed drinking vessel as shown, however in an alternative embodiment, the drinking vessel (100) can be a flat bottomed tumbler style drinking vessel having a short tubular shaped protruding portion connected to the interior of the base of the drinking vessel which is adapted to receive the threaded sleeve (103).
General
With reference to
A raised ring (132) is provided about the neck (133) of the bottle (131). This ring (132) is adapted to engage with the tamper evident seal (19), (36), (66), (85) or (108) (not shown) of the drinking vessel (10), (30), (60), (80) or (100) when it is fitted onto the bottle (131), and to prevent the tamper evident seal (19), (36), (66), (85) or (108) departing from the bottle (131) when the drinking vessel (10), (30), (60), (80) or (100) is later removed.
In
A bottle seal (105) is shown and described with reference to
It can be seen from these figures that the drinking vessel (10), (30), (60), (80) or (100) fits over the bottle (131). The upper part (135) of the bottle (131) has a smaller diameter than the lower part (137) of the bottle (131). A shoulder (139) separates the two parts of the bottle (131). The rim of the drinking vessel (141) can butt against the shoulder (139) to at least partially seal the interior of the drinking vessel (10), (30), (60), (80) or (100) during transportation and storage of the assembled drinks package (130).
Preferably the drinking vessel (10), (30), (60), (80) or (100) is sized such that at least half of the contents of the bottle (131) can be accommodated in the drinking vessel (10), (30), (60), (80) or (100).
The drinking vessel (60) described in example three above allows an alternative method of packaging a drink into a drinks package which includes a drink container and a drinking vessel, the method including the steps of,
