Definitions

  • the present invention relates to a liquid container useful as a container for an eye drop (ophthalmic solution), a nose drop (nasal solution), a contact-lens cleaning solution or the like.
  • a container for an eye drop or the like there has been commonly known a type which comprises a container body having a nozzle, and a cap detachably attachable to the container body, wherein it is designed to allow a medical solution to be instilled (dropped) from a tip end of the nozzle through an operation of gently pressing the container body while orienting the tip end of the nozzle downwardly under a condition that the cap is detached.
  • a so-called twist cap-type liquid container having a pair of lockable arms provided on an inner peripheral surface of a cap is widely used as the container for an eye drop or the like, wherein it is designed such that the cap is attached to a container body by locking the lockable arms onto a locking protrusion of the container body, and then the cap is detached by releasing the locked state between the container body and each of the lockable arms through an operation of twisting the cap to bring the cap into riding contact with a shoulder portion (a portion between a liquid storage portion and a tubular neck portion holding a nozzle) of the container body, as described in JP 10-329855.
  • twist cap-type liquid container is capable of obtaining a stronger clicking feeling when the lockable arms are engaged with the locking protrusion, to allow a user to check an attached state of the cap based on the clicking feeling
  • a sub-type designed to obtain stronger clicking feelings is also widely used, which has a protrusion provided on the container body, e.g., on a top end of the shoulder portion, in addition to the aforementioned locking protrusion, and a corresponding protrusion provided on an inner surface of the cap, wherein a clicking feeling is obtained when the protrusion of the cap is moved to cross over the protrusion of the container body during a cap attaching operation.
  • liquid container As a production method for this sub-type of liquid container (container body), there have been commonly known a direct blow molding process designed to receive a resin material in a die to form the resin material directly into a final product shape by blow molding, and an injection blow molding process designed to form a pre-molded product by injection molding and further subject the pre-molded product to blow molding to obtain a final product.
  • the liquid container has been produced by the direct blow molding process so far. This is primarily because the direct blow molding process is advantageous in view of equipment, such as a smaller number of dies, i.e., low cost, and a capability to make dies in a short period.
  • the present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid container capable of obtaining a strong clicking feeling during a cap attaching operation and responding to production based on an injection blow molding process.
  • a liquid container comprises: a container body which has a tubular neck portion, a shoulder portion continuous with the tubular neck portion, a liquid storage portion, and a nozzle held by the tubular neck portion; and a top-closed tubular cap attachable to the container body to cover a region from the nozzle to the shoulder portion.
  • the tubular neck portion of the container body has an outer peripheral surface provided with a protrusion for locking the cap, and the cap has a pair of lockable pieces provided on an inner top region thereof to extend along the tubular neck portion and arranged in a diametral direction of the tubular neck portion.
  • the cap is adapted to be locked with respect to the container body, in such a manner that, during an operation of attaching the cap to the container body along an axial direction of the tubular neck portion, the tubular neck portion is inserted between the lockable pieces, and a pair of engagement portions formed on respective opposing surfaces of the lockable pieces are engaged with the locking protrusion.
  • the cap internally has a pair of first reinforcing ribs each formed along a surface on an opposite side of a respective one of the opposing surfaces of the lockable pieces and adapted to restrict a flexural displacement of a respective one of the lockable pieces in the arrangement direction of the lockable pieces, and a pair of second reinforcing ribs each connecting a respective one of the lockable pieces and an inner surface of the cap in a direction perpendicular to the arrangement direction of the lockable pieces.
  • the nozzle and the tubular neck portion are inserted between the pair of lockable pieces provided on the inner top region of the cap. Then, when the cap is pushed to a position where an edge of an opening of the cap comes into contact with the container body, the respective engagement portions of the lockable pieces are engaged with the locking protrusion, and thereby the cap is locked with respect to the container body.
  • the lockable pieces are bent (elastically deformed) and then elastically returned to allow a clicking feeling to be obtained.
  • the second reinforcing ribs each connecting a respective one of the lockable pieces and an inner surface of the cap are provided. This makes it possible to efficiently increase the rigidity of each of the lockable pieces by utilizing a narrow internal space of the cap.
  • each of the engagement portions is provided in a distal end region of a corresponding one of the lockable pieces, and each of the first reinforcing ribs is formed over a region from a base end approximately to a distal end of a corresponding one of the lockable pieces, wherein a width of the first reinforcing rib in a direction perpendicular to a thicknesswise direction of the first reinforcing rib decreases in a direction from the base end to the distal end.
  • each of the second reinforcing rib is provided in a vicinity of the base end of a corresponding one of the lockable pieces.
  • This structure makes it possible to adequate permit a flexural (bending) deformation in the distal end region (portion provided with the engagement portion) of each of the lockable pieces while increasing the rigidity of the entire lockable piece, so that the lockable piece can be adequately locked to the locking protrusion while being elastically deformed along with pushing of the cap, and a clicking feeling to be produced during the locking can be effectively enhanced.
