Definitions

  • the present solution relates to a spout for a food package.
  • the present solution relates to a spout, according to the preamble of claim 1, having a membrane sealing an end of said spout; and to a spout, according to the preamble of claim 6, provided with a cut surface after separating a membrane.
  • 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, including 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.
  • a cap assembly and a method for capping the same is disclosed.
  • a mechanism is disclosed where a cap is put over a mouth of a bottle during capping and where part of an inner stopper can be removed through unscrewing the cap in the closing direction thus breaking a junction section. Further unscrewing the cap in the opening direction will lift the lid section the inner stopper together with the cap from the bottle while holding the lid section in the cap.
  • the solution is provided by a spout forming part of a neck of a package according to claim 1.
  • the spout comprises a membrane and a tubular member having a main body and an end portion extending axially from the main body where the tubular member is releasably attached to the membrane and wherein the end portion is arranged radially inwards of the main body and where the end portion has an inner surface, the main body has an inner surface as well and where the inner surface of the end portion is arranged radially inwards of the inner surface of the main body.
  • a spout forming part of a neck of a package according to claim 6.
  • This spout comprises a tubular member having a main body provided with a cut surface after separating a membrane from the neck.
  • the spout includes a tubular end portion initially extending axially from the main body from the tubular member where the cut surface extends radially inwards and downwards from an upper free end of the main body and the cut surface is arranged ata distance from a position where the upper free end connects with the outer surface of the main body.
  • the solution is provided a package for containing liquid foodstuffs therein comprising a neck assembly with a spout according one of the embodiments above, where the package further comprises a cap which is configured to close the spout.
  • the cap comprises at least one cutting element configured to separate the membrane from the tubular member of the spout (100).
  • 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 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, which may be moulded on top of the tubular body.
  • the shoulder section 13 is thus arranged to connect the sleeve, which forms the 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 through moulding, or as two separate pieces which are moulded together.
  • the sleeve is filled with food content.
  • this is done after the top portion 12 has been moulded onto the sleeve and the package is orientated upside down, such that the remaining open end of the sleeve is facing upwards.
  • After filling 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 spout 100, as well as for retaining the cut-off membrane 150.
  • cutting elements 50 are arranged following the threads 32 cutting elements 50.
  • the purpose of the cutting elements or knives 50 is to penetrate a section of the spout 100, immediately below the membrane 150, and to separate that membrane 150 from the rest of the spout 100.
  • 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 technical reason is that the membrane 150 serves an important purpose when resealing the closure.
  • the 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, 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. So, 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 spout 100.
  • 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 spout 100.
  • 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 application of the cap 30 or when 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.
  • the region 54 is the cutting region of the cutting element 50, and in this region the thickness of the cutting element 50 is reduced to form a cutting edge 54.
  • the cutting edge 54 may be rectilinear, as in the present embodiment.
  • the free end 56 remote to the hinged attachment may preferably be blunt, and may preferably be 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 spout 100 when it is not supposed to. This may e.g. be important when the cap 30 is arranged on the spout 100 for the first time.
  • the cap 30 is 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 (i.e. in a direction towards the contents of the package 10 in Fig. 1 ) when the cap 30 is unscrewed from the neck 20, whereby the cutting elements 50 will be urged inwards (i.e. in the direction toward the neck) and thus cut off the membrane 150 from the neck 20.
  • the cutting elements 50 are subject 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 extends 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.
  • FIGs. 4-6 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.
  • the cap 30 has been screwed back onto the neck 20.
  • the cutting elements 50 will however be disengaged from the membrane 150 when the membrane 150 is reaching the open spout 100 of the neck 20.
  • the membrane 150 will rest on the spout 100 while the cap 30 moves down the neck 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.
  • 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 spout 100.
  • Figs. 7a-c details of the spout 100 will be described.
  • the spout 100 is defined as the upper part of the neck 20 through which the package content is discharged. Prior to opening of the package the spout 100 thus comprises the membrane 150. However, once opened, the membrane 150 is separated from the spout 100.
  • the spout 100 is shown prior to opening of the package, i.e. the membrane 150 forms part of the spout 100.
  • the spout 100 forms the upper part of the neck 20, approximately starting from the shoulder 24 and extending upwards.
  • the spout 100 is formed by a tubular member 110 extending from the shoulder 24 of the neck and upwards.
  • the tubular member 110 has a main body 112 and an upper end portion 114 which forms the connection to the membrane 150.
  • the cutting elements 50 of the cap 30 will cut through the upper end portion 114 of the spout 100 such that the membrane 150 is separated from the main body 112 of the tubular member 110, as will be further explained with reference to Fig. 7c .
  • the membrane 150 forming a circular closure of the spout 100, 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 a, and the membrane flange 170 is connected to the outer annular disc member 154 at an angle ⁇ .
  • These angles facilitate 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.
  • the sealing lip 160 Upon such increase of the membrane's 150 diameter, the sealing lip 160, initially projecting downwards, will be urged towards the inner sidewalls of the main body 112 of the tubular member 110.
  • Fig. 7b the connection between the tubular member 110 and the membrane 150 is shown in further detail.
  • the membrane flange 170 is formed by two adjoining parts; an outer portion 172 which extends radially outside the end portion 114 of the tubular member 110, and an inner portion 174.
  • the end portion 114 of the tubular member 110 is attached to the interface between the inner and outer portions 172, 174 of the membrane flange 170.
  • the end portion 114 of the tubular member 110 thus extends from the upper end of the main body 112 to the interface between the inner and outer portions 172, 174 of the membrane flange 170.
  • the axial length of the end portion 114 may e.g. be in the range of 0.1-0.4 mm.
  • the position of the end portion 114 is radially offset the main body 112. More particularly the end portion 114 has a first thickness, or radial width, while the main body 112 has a second thickness, or radial width. These widths may or may not be the same.
  • the end portion 114 has an outer surface 114a which is connected to the main body 112 at a position being arranged radially inwards of the outer end 112a of the main body 112.
  • An inner surface 114b of the end portion 114 is not flush with an inner surface 112b of the main body 112 but instead the inner surface 114b of the end portion 114 is arranged radially inwards of the inner surface 112b of the main body 112.
  • the dashed line 115 indicates the cutting line when the membrane 150 is separated from the spout 100 for the first time.
  • the cutting action caused by the cutting elements 50 will be directed downwards and inwards, such that the cutting elements 50 will cut from the position where the outer surface 114a of the end portion 114 meets with the main body 112 to the position where the inner surface 112b of the main body 112 meets with the end portion 114.
  • the distance required to cut through is actually the shortest possible such that the cutting action is performed on a minimum material thickness.
  • Fig. 7c The separation of the membrane 150 from the spout 100 is shown in Fig. 7c .
  • the end portion 114 which now is cut loose from the main body 112, is left with a cut surface 114c.
  • This surface 114c may be provided with a certain roughness but since it is connected to the membrane 150 rather than to the spout 100 the potentially rough surface 114c will not risk coming into contact with the lips of a consumer.
  • the main body 112 is also provided with a cut surface 112c. Also this surface 112c may be rough to some extent. However, this surface 112c will now mainly be arranged at the inner surface 112b of the main body 112 which normally not will come into contact with the lips of the consumer. After separating the membrane 150 the spout will thereby have a main body 112 of which the upper free end 112d will be provided with a cut surface 112c extending radially inwards and downwards. Preferably, the cut surface 112c does not extend radially outwards to a position where the upper free end 112d connects with the outer surface 112a of the main body 112.
