Definitions
- the present invention relates to a cap and neck assembly for a food package.
- the present invention relates to a cap and neck assembly, of which the neck has a membrane sealing an open end of said neck.
- Food packages are generally provided with an opening device in order to facilitate discharging of the enclosed food product.
- the opening device may either be an irreversible opening, i.e. once the package is opened it may not be closed, or a recloseable opening device. In order to extend the shelf-life and quality of the food product the latter is often desired.
- a common way of providing a recloseable opening device is to arrange a threaded neck including a pouring spout on the upper part of the package.
- the threaded neck is designed such that it may receive a cap, having internal threads such that the cap is capable of being unscrewed from the neck. Since the cap covers the open spout of the neck, the enclosed food product is protected from the outer environment and the quality of the product may thus be preserved during some time.
- WO2011144569 a solution is described in which the spout is provided with a membrane.
- the membrane which initially is connected to the spout leaving the spout perfectly closed, is cut from the spout during an opening action, i.e. when the cap is unscrewed from the neck.
- WO2013072475 describes a cap and neck assembly having a membrane for sealing the food package.
- the membrane is shaped such that it is angled at an outer end towards the inner sidewalls of the spout thereby allowing for improved re-sealing of the food package when the cap is screwed onto the neck.
- the invention is based on the provision of a tubular member, at one end connected to the membrane at a position radially inwards of the sidewalls of the neck, which tubular member is used to seal against the sidewalls of the neck.
- the free end of the tubular member has an angled surface for sliding the membrane on the inner walls of the neck when sealing and/or re-sealing.
- the solution is provided by a cap and neck assembly for closing an upper end of a package,
- the assembly comprises a neck forming part of an upper end of a package, the neck comprising a tubular member being provided with external threads, and an upper tubular portion extending from the tubular member and being releasably attached to a membrane closing an upper end of said upper portion, the membrane having a membrane flange protruding radially outside the tubular member.
- the assembly also comprises a cap in the form of a tubular body having a lower portion being provided with internal threads for engagement with the threads of the neck, and an upper portion forming a closed upper end, the upper portion being provided with at least one cutting element configured to separate the membrane from said tubular member of the neck.
- the cap is threaded onto the neck to its axial end position for the first time prior to separating the membrane from the neck, the axial distance between a cutting edge of the cutting element and the membrane flange is between 0,5mm and 1mm.
- the solution is provided by a package comprising a cap and neck assembly mentioned earlier as the first aspect of the solution.
- the food package 10 has a shape of a bottle formed by a body portion 11, which may preferably be made of a carton-based laminate and a top portion 12, which may preferably be made of plastic.
- the top portion 12 is provided with a neck 20 forming the upper part of the plastic top portion 12.
- the neck 20 may be integrally formed with the top portion 12, such that the entire top portion 12, including the neck 20, may be manufactured as a single piece.
- a cap 30 is arranged onto the neck for sealing a spout 100 (see e.g. Fig. 2b ) forming the upper end of the neck 20.
- the cap 30 may optionally be provided with a tamper ring 40 as is well known in the art.
- the cap 30 and neck 20 together forms a cap and neck assembly.
- the package 10 may be manufactured by first forming a sleeve of the carton-based laminate, i.e. a tubular body extending between two open ends.
- the plastic top portion 12 is manufactured by molding.
- the plastic top portion 12 may, as is shown in Fig. 1 , comprise a shoulder section 13 arranged below the neck 20 and to which the tubular body is later attached.
- the shoulder section 13 is thus arranged to connect the sleeve, which forms basis for the body portion 11, to the neck 20.
- the neck 20 is preferably provided with threads for engaging with corresponding threads of the cap 30 including the tamper ring 40.
- the neck 20 and the shoulder section 13 may be provided as one piece, or as two separate pieces which are molded together.
- the sleeve is filled with food content.
- this is done by turning the sleeve and the top portion 12 assembly upside down, such that the remaining open end of the sleeve is facing upwards.
- the open end of the sleeve may be sealed and folded to a flat bottom as illustrated in Fig. 1 .
- the cap 30 is screwed onto the top portion 12 after the package 10 is filled. This may e.g. be the case if the neck 20 is provided with a membrane 150 (see Fig. 2b and onward) sealing the spout 100 of the neck 20, which will be described in more detail below.
- the cap 30 including the tamper ring 40, is shown in Fig. 2a .
- the cap 30 has a lower portion 31 being provided with internal threads 32.
- the threads 32 are configured to engage with corresponding threads 22 of the neck 20 (see e.g. Fig. 2b ).
- the lower portion 31 extends into an upper portion 33 which forms the closed upper end of the cap 30.
- the interior of the upper portion 33 is provided with means for separating the membrane 150 from the neck 20, as well as for retaining the cut-off membrane 150.
- cutting elements 50 are arranged following the threads 32 .
- the purpose of the cutting elements or knives 50 is to penetrate a section of the neck 20, immediately below the membrane 150, and to separate the membrane 150 from the rest of the neck 20.
- the cutting elements 50 serve the purpose of securing the membrane 150 in an axial position (i.e. along the A-axis in Fig. 2A ) between the cutting elements 50 and the interior of the top part of the upper portion 33. This will reduce the amount of litter generated, yet the main technical reason is that the membrane 150 serves an important purpose when resealing the closure.
- the exact number of cutting elements 50 will depend on several factors, yet one important factor is the rising of the threads 32.
- the cutting action is effected when unscrewing the cap 30 for the first time, and the cutting elements 50 will follow the rotational motion of the cap 30 as well as the axial movement thereof, all relative to the neck 20. This implies that the cutting action, or "removal action" to be more general, have to be finalized within a certain turning angle since otherwise the axial movement will move the cutting element 50 out of reach from the area to be cut. Hence, the steeper the rising of the threads, the more cutting elements 50 are needed.
- each cutting element 50 will generate a torque resistance when the cap 30 is unscrewed the first time, and in order to reduce the opening torque to acceptable levels it is not wise to have too many cutting elements 50.
- five cutting elements 50 have been used, yet it is up to the skilled person to deduce a suitable number.
- one cutting element 50 is sufficient to perform the cutting action in order to separate the membrane 150 from the neck 20.
- at least three cutting elements 50 are necessary to perform the cutting and the membrane 150 retaining action, after the membrane 150 has been cut off from the neck 20.
- stop elements 60 are arranged at about the same axial position as the cutting elements 50 stop elements 60 are arranged.
- the stop elements 60 are realized by stop ledges, i.e. flanges extending from the top part of the upper portion 33 down to a specific axial position, and a small distance radially inwards. It should be noted that within the context of this specification, all references to "axial” or “radial” should be interpreted as shown by the dashed arrows in Fig. 2a . The axial direction is indicated by the letter “A”, while the radial direction is indicated by the letter "R".
- stop elements 60 there are a total of five stop ledges 60 and they are dimensioned so as to allow for the membrane 150 to fit between them.
- the purpose of the stop elements 60 is to prevent the cap 30 from being screwed too far down (i.e. in a closing direction) onto the neck 20, and thus to prevent damage to the membrane 150 during resealing the closure after initial opening.
- the stop elements 60 of the cap 30 cooperate with a counter element 24 of the neck 20 (see Fig. 2b ).
- the counter element 24 is represented as a shoulder extending radially outwards.
- FIG. 2c An example of a cutting element 50 is shown in further details in Fig. 2c .
- the cutting element 50 is shown from above.
- the cutting element 50 is attached to the inner perimeter of the cap 30, at an axial position indicated in Fig. 2a .
- the cutting element 50 is allowed to pivot by means of a hinge connection with the inner perimeter of the cap 30.
- the hinge connection is in this embodiment realized by a reduced thickness at an area 52 immediately adjacent to the inner perimeter of the cap 30.
- Each cutting element 50 may be provided with a cutting edge 54 and a free end 56.
- the free end 56 is located remote to the hinged attachment 52 and it may preferably be blunt, and less sharp than the cutting region 54. The result is the benefit that the free end 56 is not prone to damage the connection region between the membrane 150 and the rest of the neck 20 when it is not supposed to. This may e.g. be important when the cap 30 is arranged on the neck 20 for the first time.
- the cap 30 is assumed to be screwed onto the neck 20 for the first time, i.e. when the membrane 150 is attached to the neck 20.
- the cutting elements 50 will bend downwards when the cap 30 is unscrewed from the neck 20, whereby the cutting elements 50 will be urged inwards and thus cut off the membrane 150 from the neck 20 once the cap is unscrewed from the neck 20.
- the cutting elements 50 are biased to an idle position in which they protrude over a radially outer part of the membrane 150, more specifically a free end of the cutting elements 50 extend past a circumferential edge of the membrane 150. Hence, the cutting elements 50 will retain the membrane 150 within the cap 30 after the cap 30 has been completely unscrewed from the neck 20.
- a closing sequence of a cap and neck assembly is shown. Prior to such sequence, it is assumed that the cap 30 has once been unscrewed from the neck 20 such that the membrane 150 has been separated from the neck 20, while still being retained at the inner upper portion of the cap 30 by means of the cutting elements 50.
- the cap 30 has been screwed onto the neck 20.
- the cutting elements 50 will however be disengaged from the membrane 150 when the membrane 150 is reaching the open end of the neck 20.
- the membrane 150 will rest on the open end of the neck 20 while the cap 30 moves down the neck 20 due to the provision of the threads, converting a rotational movement to a vertical movement.
- the membrane 150 is on its upper side in contact with the closed end of the cap 30, while it rests on the open spout 100 of the neck 20 on its lower side.
- the closed end of the cap 30 will interact with the membrane 150 thus pressing it downwards.
- the membrane 150 will flex such that its diameter increases, whereby a sealing lip 160 of the membrane 150 moves towards the interior side of the upper end of the neck 20.
- Figs. 7a-b details of the neck 20 will be described.
- the neck 20 Prior to opening of the package the neck 20 comprises the membrane 150, however once opened the membrane 150 is separated from the neck 20.
- the neck 20 is shown prior to opening of the package, i.e. the membrane 150 forms part of the neck 20.
- the neck 20 extends from the shoulder section 12 and upwards.
- the neck 20 is formed by a tubular member 110 extending from the shoulder 24 of the neck and upwards.
- the tubular member 110 is provided with the threads 22, and its axial end position is defined as coinciding with counter element 24. From here, the neck 20 extends further upwards by means of an upper portion 120 forming a main body 122 and an upper end portion 124.
- the upper end portion 124 forms the connection to the membrane 150. During opening, the cutting elements 50 of the cap 30 will cut through the upper end portion 124 such that the membrane 150 is separated from the upper portion 120.
- the membrane 150 forming a circular closure of the neck 20, comprises a central circular disc member 152 and an outer annular disc member 154.
- the outer annular disc member is arranged radially in between the central circular disc member 152 and a membrane flange 170.
- the outer annular disc member 154 is connected to the central circular disc member 152 at an angle ⁇
- the membrane flange 170 is connected to the outer annular disc member 154 at an angle ⁇ .
- These angles facilitates the flexing of the membrane 150 during re-sealing, such that the entire diameter of the membrane 150 may increase as the angles ⁇ , ⁇ increases due to a downward pressing action at the centre of the membrane 150.
- a sealing lip 160 Upon such increase of the membrane's 150 diameter, a sealing lip 160 will be urged towards the inner sidewalls of the upper portion 120. In an idle position where no downward force is applied to the membrane 150 the sealing lip 160 is projecting downwards.
- Fig. 7b showing an enlarged portion of the neck 20, the connection between the upper portion 120 and the membrane 150 is shown in further detail, as well as details of the upper portion 120 of the neck 20.
- the membrane flange 170 is formed by two adjoining parts; an outer portion 172 which extends radially outside the upper end portion 124 of the upper portion 120, and an inner portion 174.
- the upper end portion 124 of the upper portion 120 is attached to the interface between the inner and outer portions 172, 174 of the membrane flange 170.
- the upper portion 120 has a certain axial length L1.
- the axial length L1 is preferably defined as the distance between the counter element 24 and the membrane flange 170. In a preferred embodiment, the axial length L1 is between 5mm and 5,5mm.
- the axial length L1 determines the position of the cutting elements 50 relative the membrane 150 when the cap 30 is initially screwed onto the neck 20.
- the axial length L1 determines the position of the cutting elements 50 relative the membrane 150 when the cap 30 is initially screwed onto the neck 20.
- Fig. 8 the relationship between the cutting elements 50 and the membrane 150 is shown in further detail.
- the position of the cap 30 corresponds to a fully capped position, i.e. the tamper ring 40 prevents further downward rotation of the cap 30.
- the cutting elements 50 are positioned below the membrane flange 170, such that the axial distance D1 between the cutting edge 54 of the cutting elements 50 and the membrane flange is below 1mm.
- the axial distance D1 is approximately 0,7mm.
- the threads 22, 32 are preferably configured such that the axial end position of the cap 30, for the first time prior to separating the membrane 150 from the neck 20, is reached after rotating the cap 30 between 300° and 315°.
- the axial length D2 of the upper portion 33 of the cap 30 measured from the inside surface of the recessed portion 34 of the cap 30 until the end 62 of the stop elements 60 is for this purpose selected to be between 5mm and 6mm, such that the neck 20 fits within the cap 30.
- D2 should be chosen such that the force exerted by the cap 30 onto the membrane 150 should not be too high, since this may cause the membrane to arch in the direction of the interior of the package thus moving the membrane flange 170 and the sealing lip 160 away from neck portion 100 of the container. Such a movement may result in a local loss of sealing between the sealing lip 160 and the neck portion 100.
- axial length D3 between the inner surface of protruding portion 35 of the cap 30 and the inner surface of the recessed portion 34 of the cap.
- D3 should be chosen such that the membrane flange 170 has sufficient space to move during re-sealing of the cap 30, when the membrane 150 arches towards the inside of the container.
- the cutting elements 50 are provided at the lower end of the upper portion 33.
- Fig. 9 the opening action is shown from a position at which the cap 30 is screwed onto the neck 20 for the very first time, i.e. when the membrane 150 is formed integral with the neck 20. Initially a rather high torque is required for breaking the tamper ring 40 from the neck 20.
- the torque then decreases until the cap 30 has been rotated approximately 50-60°, corresponding to an axial movement sufficient to allow the cutting elements 50 to engage with the neck/membrane interface. Once this occurs the torque again increases until the membrane 150 is separated from the neck 20. This is effected approximately 200-220° from the initial position.
