Definitions

  • the present disclosure relates generally to closures for containers, such as plastic disposable containers and the like. More particularly, the present disclosure relates generally to closures for containers adapted to be press-fit to a container and configured to be subsequently threadably removed therefrom.
  • infant nutritionals, adult and medical nutritionals, sport nutritionals, energy drinks, soft drinks, and the like often times are provided in plastic bottles or other disposable containers.
  • the bottles are typically sealed after being filled with a product to prevent product degradation and/or contamination of the product.
  • Foil seals may be particularly desirable for products that are aseptically processed.
  • Sealing film such as foil or plastic film, commonly referred to as "seals," is generally considered the most robust form of a sealing closure for plastic bottles.
  • Screw caps are also used for sealing containers.
  • screw caps are difficult to install onto containers during the manufacturing process, as compared to foil seals.
  • removal of a screw cap may entail application of removal torque sufficient to break a tamper evident seal, overcome the frictional forces of the threads, and also the force required to break the seal of the container.
  • screw caps may be difficult for elderly or arthritic individuals due to requiring a high removal torque, such as more than 1.69 Nm (15 in lbs), with many containers requiring 2.26 Nm (20 in lbs) of removal torque to open.
  • Other screw caps may also include a shrink band that covers the cap for tamper evidence. However, such tamper evident shrink bands may also be difficult for individuals to remove, and require the additional step of removing and discarding the shrink band before unscrewing the cap.
  • a closure for a glass container the glass container having an opening through which contents of the container are dispensed and an annular groove for cooperating with the closure to retain the closure on the container.
  • the closure comprises a cap configured to close the container opening, the cap including a radial bead engagable with the annular groove of the glass container to retain the cap in engagement with the container.
  • the closure also comprises an overcap.
  • the overcap has a top and a sidewall depending from the top. The sidewall includes threads for attachment to the glass container, the overcap being rotatable relative to both the cap and the glass container.
  • a container having a body with a cylindrical neck forming an opening and a cover with a base and cylindrical edge.
  • An engagement system with a threaded action is provided on the neck and cylindrical edge.
  • a seal is provided separately between the cover and the edge of the opening.
  • the seal has a rigid edge which co-operates with an abutment provided in the cover in an axial direction after the thread has been disengaged.
  • the seal has a circular groove which contains a gasket and the groove also has a base which is directed towards the base of the cover and forms a contact surface in contact with the contact face of the cover. One of the contact faces is curved and the other is flat.
  • the present disclosure is directed to closures for various types of containers, including plastic, metal, composite and glass containers.
  • the closures described herein are capable of being snap-fit (also interchangeably referred to herein as "press-fit") to a container using a downward force, yet removed by unscrewing the cap from the container.
  • the described closures are two piece closures including a sealing member that is snap-fit to the container independently of the cap member, such that the cap member is capable of rotating independently of the sealing member.
  • a method of applying a closure to a container comprising: press-fitting a sealing member onto the container over the container opening such that a retention member of the sealing member engages a holding member of the container, an axial force resulting from said press-fitting retaining the sealing member in sealing engagement with the container to sealingly close the container opening; and applying a cap member to the container at the sealed container opening, the cap member including a top rim and a sidewall depending therefrom, the sidewall including an attachment member for engagement with the container, and an engagement member coupling the sealing member to the cap member upon application of the cap member to the container, the cap member being rotatable relative to both the container and the sealing member, wherein the step of applying the cap member to the container is performed after the step of press-fitting the sealing member onto the container and wherein the step of press-fitting the sealing member onto the container occurs in a sterile area of a capping
  • the present disclosure describes closures for various types of bottles and containers.
  • the closures described herein substantially provide a hermetic seal for aseptically filled containers by using a press-on sealing member and twist-off cap.
  • the present disclosure provides a solution to the longstanding problem of removing a cap and seal of a container in a single step without a high removal torque.
  • the closures described herein accomplish this by, for example, a pressed on sealing member that hermetically seals the container, and a cap member that is twisted on/off and which removes the sealing member when twisted off.
  • Articles "a” and “an” are used herein to refer to one or to more than one (i.e. at least one) of the grammatical object of the article.
  • an element means at least one element and can include more than one element.
  • the present disclosure describes closures for containers that may provide functionality to hermetically seal a container using a sealing membrane and provide removal of the closure using a low torque twist-off cap.
  • the containers may be generally any suitable packaging for containing substances including, without limitation, glass, metal or plastic bottles, plastic containers, bags or pouches constructed of films or other plastics, and other suitable packaging.
  • the containers disclosed herein may be suitable for use with nutritional substances.
  • the term “substance” may refer to a liquid product, a semiliquid product, or powder product.
  • liquid product means a product that is a flowable non-solid product including, for example but not limited to, aqueous solutions, solutions having a determinable viscosity, emulsions, colloids, pastes, gels, dispersions and other flowable non-solid products so as to exclude solid products such as bars and particulate products, such as powders.
  • Figs. 1-3 show a container and closure assembly 100.
  • Closure 105 is adapted to close container 110.
  • Container 110 comprises a body 120 and a neck 130.
  • neck 130 is generally cylindrical in shape, and container 110 is symmetric about longitudinal axis C. In other arrangements, container 110 may be non-symmetric, or symmetric about one or more axis.
  • Container 110 may be any shape that allows the closures to function as described herein.
  • Neck 130 includes a set of threads 135 on an outer surface 140 thereof. As used herein, the terms “inner” and “outer” may refer generally to a radial direction of container 110 and/or closure 105.
  • Set of threads 135 may include one or more threads that helically wrap at least partially around outer surface 140.
  • Neck 130 includes an inner surface 145 that connects to outer surface 140 at a rim 150, which defines container opening 155.
  • Container 110 may contain a substance, such as a liquid substance.
  • closure 105 is a single piece closure fitted to neck 130 of container 110 ( Fig. 1 ).
  • Closure 105 includes threads 160 that couple closure 105 to container 110 by threaded engagement with threads 135.

  • closure 105 includes a top 190 and a substantially cylindrical sidewall 195. In one arrangement, an annular lip 200 is provided on a lower surface of top 190.
  • closure 105 is first placed over opening 155 such that a center of closure 105 is substantially aligned with central axis C. Closure 105 is then press-fit onto neck 130 by applying a force to closure 105 in the longitudinal (i.e., axial) direction of container 110 ( Fig. 1 ) (e.g., the downward direction when the container and closure are in the upright position).
  • sidewall 195 is configured to flex radially outward such that ramps 180 pass over threads 135 and locking projection 185. Sidewall 195 also flexes to allow threads 160 to pass over threads 135.
  • the closure is pressed onto container 110 until a lower surface of top 190 contacts rim 150. At this point, closure 105 is considered to be "snap-fit" onto container 110.
  • the snap-fit may make a "snapping" noise or other audible indication as one or more elements of closure 105 pass over and engage with elements of container 110. However, even if no audible indication occurs, closure 105 is still considered to be snap-fit to container 110 when pressed thereon and sealed thereto.
  • closure 105 may be determined to be snap-fit to container 110 by sensing a force applied to closure 105 or the displacement of closure 105.
  • a sensor may measure and compare the applied force to closure 105 to a predetermined force, and when the applied force is within a certain range of the predetermined force, the closure is determined to be snap-fit.
  • closure 105 may be determined to be snap-fit to container 110 after the closure has moved longitudinally a predetermined distance along neck 130. The distance closure 105 moves along neck 130 is measured and compared to a predetermined distance, and if the measured distance is within a range of the predetermined distance, the closure 105 is determined to be snap-fit to container 110.
  • closure 105 In order to remove closure 105 from neck 130 of container 110 ( Fig. 1 ), a user applies a torque in an opening rotation direction to closure 105.
  • the torque in the opening direction causes closure 105 to threadably move in the longitudinal direction away from container 110, which breaks the sealing engagement of top 190 with rim 150.
  • the applied torque in the opening rotation direction causes frangible bridges 175 to break, indicating that the closure has been opened.
  • closure 105 is fabricated from plastic and may include a barrier layer 205 disposed on one or more of an outer surface or inner surface of top 190.
  • barrier layer 205 may be fabricated as a layer within closure 105.

  • barrier layer 205 may include a design or decorative label.
  • closure 105 includes gasket material 210 disposed on a lower or inner surface of top 190.
  • Gasket material 210 is disposed annularly around a perimeter of top 190 such that it contacts rim 150.
  • Gasket material 210 may be fabricated from a single or multi-layer film, plastisol, rubber, thermoplastic elastomer, foil, paper, plastic, laminate, other suitable sealing material or combinations thereof that is used to seal a substance within a container.
  • the gasket material 210 may be used to hermetically or aseptically seal container 110.
  • gasket material 210 is an adhesive or sealing compound, which may be activated/cured by one or more of temperature, light or the like.
  • the closure 105 may also include a hole 215, for example as illustrated in Fig. 2 . In other arrangements, closure 105 does not include a hole 215. Hole 215 may be used for cleaning, rinsing, drying or inspection of threads 135 and 160 after filling of container 110 ( Fig. 1 ) and hermetic sealing has been created with closure 105, so as to help ensure threads 135 and 160 are clean when the container is later opened and consumed by the end user.

  • sealing member 220 in order to seal container 110, sealing member 220 is first placed over opening 155 such that the center of sealing member 220 substantially aligns with the center of opening 155. Sealing member 220 is then press-fit down onto neck 130 by applying a force to sealing member 220 in the longitudinal (i.e., axial) direction of container 110. As sealing member 220 is pressed onto neck 130, outer wall 227 of sealing member 220 presses tightly (e.g., snap-fit) against outer rim edge 232 to hold sealing member 220 in sealing engagement with rim 150. In accordance with one embodiment of the present invention, sealing member 220 is press-fit onto container 110 in a sterile zone of a capping operation after container 110 has been aseptically filled with a substance.

  • cap member 225 is capable of rotating independently of sealing member 220.
  • independent rotation refers to the sealing member and the cap member being configured such that the cap member may rotate, at least for a partial turn, without causing rotation of the sealing member.
  • Cap member 225 is rotated in the closing direction until ledge 230 is firmly pressed against upper edge 240 of sealing member 220.
  • An engagement member 245 passes over upper edge 240 of sealing member 220, and is positioned below and apart from sealing member 220 when cap member 220 is fully seated (i.e., press-fit) on container 110.
  • cap member 225 includes a tamper band 170. Cap member 225 thus substantially ensures that sealing member 220 remains sealed on container 110 until desired opening of the container.
  • a user applies a torque in an opening rotation direction to cap member 225.
  • the torque in the opening rotation direction causes closure cap member 225 to rotate in the opening rotation direction independently of sealing member 220 and threadably move in the longitudinal direction away from container 110.
  • an engagement member 245 presses against lower part 250 of outer wall 227 (i.e., in a longitudinal direction away from the center of container 110) which breaks the sealing engagement of sealing member 220 with rim 150.
  • the engagement member 245 also functions to couple sealing member 220 to cap member 225 so that cap member 225 and sealing member 220 may be removed conjointly in a single operation.
  • the applied torque in the opening rotation direction causes frangible bridges 175 to break, indicating that the closure has been opened.
  • the removal torque necessary to remove closure 105 may be reduced as compared to conventional closures. For example, upon initiating removal of closure 105, a user need only impart a torque necessary to overcome the frictional forces of threads 160 sliding against threads 135, which in one arrangement may be approximately 0.56Nm (5 in lbs). In arrangements where cap member 225 includes tamper band 170, a user must also initially impart enough torque to break frangible bridges 175, which may be an additional approximately 0.56 Nm (5 in lbs). Thus, for example, if tamper band 170 is included, a user would need to only impart approximately 1.13 Nm (10 in lbs) of torque to cap member 225 in the opening rotation direction to initiate removal of closure 105.
  • the user no longer is required to impart the torque necessary to break bridges 175, thus reducing the torque back down to approximately 0.56 Nm (5 in lbs).
  • a user may encounter a slight increase in torque needed to unseat sealing member 220 from rim 150. Due to the helical shape of the threads 160 and 135, the sealing member 220 is unseated in a helical manner (rather than all at once), which reduces the torque necessary to unseat sealing member 220 from rim 150.
  • the torque necessary to unseat sealing member 220 from rim 150 is approximately 0.56 Nm (5 in lbs).
  • a user may not be required to impart more than approximately 1.13 Nm (10 in lbs) for closure removal.

  • This design is substantially similar to the embodiment illustrated in Fig. 14 , but does not include additional gasket material forming a hook retention member.
  • lower edge 250 is curled radially outwardly such that it does not substantially cover positive retention bead 355.
  • sealing member 220 is press-fit onto container 110 and forms a hermetic seal with container 110 in a sterile zone of a capping operation, after container 110 has been aseptically filled with a substance.
  • the threads 135 and optionally other portions of container 110 may be cleaned, rinsed and/or dried to ensure the threads 135, and other portions of container 110, are clean before the bottle is opened.
  • cap member 225 is fit over sealing member 220 and threadably coupled to container 110, outside of the sterile zone.
  • the use of the two piece closures described herein thus may reduce the complexity of the sterile zone of a filling and capping operation because the threaded cap member 225 may be applied outside of the sterile zone, which may improve efficiency, downtime and maintenance, and thereby reduce cost.
  • the closure 105 may be fitted onto container 110 in a container filling and fitting system utilizing one or more sterilization processes such as, for example, heating, retort processing, hot filling and high acid hot or cold filling of container 110.
  • sterilization processes such as, for example, heating, retort processing, hot filling and high acid hot or cold filling of container 110.
  • sealing member 220 is press-fit onto container 110 using a typical foil lid sealing system or snap cap sealing system using the compression portion of the sealing system to press-fit the sealing member 220.
  • Such sealing system may press-fit sealing member 220 onto container 110 with or without a partial heat, conduction or induction heating function turned on to allow for softening of gasket material 210 to assist with press-fitting and sealing of sealing member 220 onto container 110.
  • sealing member 220 may be adhered to container 110 using a contact adhesive layer or a heat sealable layer in conjunction with, or as an alternative to gasket material 210.
  • the term heat sealable layer refers to a material capable of forming a seal with container 110 upon application of sufficient heat.
  • Heat applied to sealing member 220 may soften gasket material 210 such that gasket material 210 and or the adhesive layer at least partially melts to adhere the sealing member 220 to container 110.
  • the additional adhesive layer is strong enough to adhere sealing member 220 to the container 110, yet does not provide significant additional resistance when a user desires to remove the sealing member 220 by applying a torque in an opening rotation direction to cap member 225.
  • one or more elements of closure 105 and container 110 may be fabricated from plastic, such as a substantially transparent plastic material allowing a user to view the threads before opening to ensure cleanliness.
  • one or more elements of closure 105 or container 110 are fabricated from substantially opaque materials, thus preventing light from entering container 110, and possibly degrading a substance contained therein.
  • One or more elements of closure 105 and container 110 may be made from a suitable plastic, such as high density polyethylene, polypropylene, polyethylene terephthalate or other suitable plastics, or may be made from other materials such as metal, paper, various resiliently flexible laminates and other suitable resiliently flexible materials.
  • High density polyethylene for example, can be formed to be suitably resiliently flexible and to allow for generally resilient deformation when a pressure is applied in a longitudinal direction.
  • Container 110 can be molded, such as by blow molding, injection molding or formed in other ways.
  • container 110 may be generally resiliently deformable when a pressure is applied in a radially inward direction (i.e., toward the axis C). By being resiliently deformable, the container 110 resists denting and other physical defects which may occur during shipping and storage. Moreover, a user may more readily “squeeze” the container 110 with his or her hand, causing the container to resiliently deform.
  • the resiliency of the container facilitates easier removal of the substance contained therein from the container upon squeezing of container 110. Providing such resiliency of the container 110 may also enhance the user's grip on the container. When the user releases the container 110, the sidewall thereof will substantially rebound to its original shape, without denting, creasing, or other permanent and readily visible deformation.
  • sealing member 220 is fabricated from metal, which allows for heating of the sealing member 220 for sterilization, which may eliminate the need for secondary sterilants, such as hydrogen peroxide, peracetic acid or electron beam sterilization.
  • the above described closure 105 may reduce the amount of a liquid sterilant required to sterilize a container and closure assembly as compared to a traditional screw cap due to a reduced size, surface area and complexity of the closures described herein.
