Abstract
Description
- 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.
- Heretofore, as 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.
- Particularly, a so-called twist cap-type liquid container having a lockable arm 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 arm onto a locking protrusion formed on the container body, and then the cap is detached by releasing the locked state of the lockable arm through an operation of twisting the cap with respect to the container body, as described in the following
Patent Document 1. - Meanwhile, the container for an eye drop or the like is often taken along a user, and thereby it is necessary to reliably prevent liquid leakage from the nozzle. Therefore, the container of the
Patent Document 1 is designed to prevent liquid leakage in such a manner as to provide a plug protrusion (sealing portion) on an inner top region of the cap and allow the plug protrusion to be inserted into a nozzle hole, and to allow the plug protrusion to be smoothly inserted into the nozzle hole during the cap attaching operation in such a manner as to provide a guide portion around the plug protrusion to adjust respective positions of the nozzle and the plug protrusion. - However, in the container described in the
Patent Document 1, during the cap attaching operation, a nozzle portion is guided while being brought into contact along a guide portion provided on the cap, so that repetition of the cap attaching/detaching operations would be likely to cause deformation or the like in the nozzle, which poses a problem for droplet formation. Particularly, in a container (for example, the following Patent Document 2) where a ring-shaped protrusion is formed on an outer periphery of a nozzle to prevent dripping (dribbling) from the nozzle and adequately form a droplet irrespective of a posture (instillation angle) of a container body to improve instillation performance, a distal end of the ring-shaped protrusion is guided along a guide portion of a cap, so that repetition of cap attaching/detaching operations would be likely to cause deformation or the like in the ring-shaped protrusion, which harms the anti-dripping function and the droplet-forming function. Moreover, only the distal end of the ring-shaped protrusion is brought into contact along the guide portion of the cap in the above manner, so that there is another problem of difficulty in stably guiding the nozzle along the guide portion during the cap attaching operation. Thus, it is expected to improve these problems based on a rational structure. - Patent Document 1:
JP 10-329855A - Patent Document 2:
JP 2004-196417A - The present invention has been made in view of the above circumstances, and an object thereof is to allow a cap to be adequately guided and attached to a container body, while preventing a disadvantage such as deformation of a nozzle.
- In order to achieve this object, the present invention provides a liquid container which comprises: a container body having a tubular neck portion and a nozzle portion integrally provided on a top end of the tubular neck portion; and a top-closed tubular cap having a sealing portion to seal a nozzle hole of the nozzle portion, said cap being attachable to the container body to cover the nozzle portion and the tubular neck portion. In the liquid container, the container body is configured such that the tubular neck portion is formed to have an outer diameter dimension greater than a maximum diameter dimension of the nozzle portion, and a protrusion for locking the cap is provided on an outer peripheral surface of the tubular neck portion, 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, wherein 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 the locking protrusion is inserted into a pair of locking concave portions formed in respective opposing surfaces of the lockable pieces, wherein the lockable pieces have respective guide surfaces which are adapted, during the operation of attaching the cap to the container body, to come into contact with the outer peripheral surface of the tubular neck portion to guide the cap along the tubular neck portion so as to allow the nozzle hole and the sealing portion to become opposed to each other.
- In this liquid container, when the cap is attached along the axial direction of the tubular neck portion of the container body, the nozzle portion and the tubular neck portion are inserted between the pair of lockable pieces provided on the inner top region of the cap, and the respective guide surfaces of the lockable pieces come into contact with the outer peripheral surface of the tubular neck portion to guide the cap along the axial direction of the tubular neck portion. The cap is guided along the guide surfaces of the lockable pieces in the above manner, so that the nozzle hole is aligned with the sealing portion. Then, when the cap is pushed along the axial direction of the tubular neck portion to a given dead end position, the locking protrusion of the tubular neck portion is inserted into the locking concave portions formed in the opposing surfaces of the lockable pieces, and thereby the cap is locked with respect to the container body. Thus, this liquid container is free of guiding the nozzle portion while bringing it into contact along a guide portion provided on the cap as in the conventional container, so that it becomes possible to prevent deformation or the like in the nozzle due to the contact. In addition, the guide surfaces for the tubular neck portion are integrally provided on the lockable pieces for locking the cap to the container body, so that the aforementioned effects can be obtained with a rational structure.
- As a specific structure, the guide surface of each of the lockable pieces may have a shape which corresponds to a cross-sectional shape of the outer peripheral surface of the tubular neck portion so as to allow the guide surface to come into contact with the outer peripheral surface continuously in a circumferential direction thereof, or may be formed to come into contact with the outer peripheral surface of the tubular neck portion intermittently in the circumferential direction thereof.
- The above structure is useful particularly in a liquid container where the nozzle portion has a ring-shaped protrusion formed on an outer periphery thereof as a portion having the maximum diameter dimension.
- Specifically, the ring-shaped protrusion is formed on the outer periphery of the nozzle portion to prevent dripping from the nozzle portion and allow a droplet to be adequately formed irrespective of a posture (instillation angle) of the container body to improve instillation performance. The above structure is free of guiding the nozzle portion while bringing it into contact along a guide portion provided on the cap, during the cap attaching operation, so that it becomes possible to prevent deformation or the like in the ring-shaped protrusion and thus adequately maintain the aforementioned functions on a long-term basis.

FIGS. 1 and2 illustrate a substantial part of a liquid container according to the present invention. - The liquid container (hereinafter abbreviated as "container") illustrated in
FIGS. 1 and2 is a so-called twist cap-type container. In this embodiment, this container is an eye drop container which comprises acontainer body 1 having anozzle portion 14, and acap 2 detachably attachable to thecontainer body 1 to cover thenozzle portion 14, wherein it is designed, during instillation, to allow a medical solution contained in thecontainer body 1 to be instilled from a tip end of the nozzle portion through an operation of gently pressing thecontainer body 1 while orienting the tip end of the nozzle portion downwardly under a condition that thecap 2 is detached. - As shown in
FIG. 1(b) , thecontainer body 1 is formed in a flat shape in a forward-rearward direction (upward-downward direction inFIG. 1(b) ). Thecontainer body 1 is configured such that a circulartubular neck portion 12 having a cross-sectionally circular shape is provided in a central position of an upper portion thereof through ashoulder portion 10, and thenozzle portion 14 is provided on a top of the circulartubular neck portion 12, wherein a portion other than thenozzle portion 14 is integrally molded using a synthetic resin, such as polypropylene, polyethylene or polyethylene terephthalate. - The
nozzle portion 14 is integrally provided in thecontainer body 1 by press-fitting a shaft-shaped nozzle body formed separately from the circulartubular neck portion 12 and others, into the circulartubular neck portion 12. Thenozzle portion 14 is molded using a soft synthetic resin, such as low-density polyethylene, linear low-density polyethylene, high-density polyethylene or polypropylene. - As shown in
FIGS. 1 and2 , thenozzle portion 14 has a ring-shaped protrusion 15 provided on an outer periphery thereof, and a constricted region provided on the side of a base end (on a lower side) thereof with respect to the ring-shaped protrusion 15. In other words, it is configured to prevent dripping from thenozzle portion 14 by the ring-shaped protrusion 15, while allowing a droplet to be adequately formed in a region of the ring-shaped protrusion 15 during instillation, irrespective of a posture (instillation angle) of thecontainer body 1. - An outer diameter dimension of the circular
tubular neck portion 12 is set to be greater than a maximum diameter dimension of the nozzle portion 14 (in this embodiment, an outer diameter of the ring-shaped protrusion 15), so that, in a state after thecap 2 is attached to the container body 1 (hereinafter referred to simply as "cap-attached state"), a gap is defined between an after-mentionedlockable arm 24 and thenozzle portion 14 to allow thecap 2 and the ring-shaped protrusion 15 to be maintained in non-contact relation. - As shown in
FIG. 1 (inFIG. 1(b) , only a part of thecap 2 is illustrated by the solid line for the sake of simplicity) andFIG. 2 , thecap 2 is formed in a top-closed tubular shape to cover a region above theshoulder portion 10. Further, it is configured such that, in the state after being attached to thecontainer body 2, a lateral surface of thecontainer body 1 and a lateral surface of thecap 2 form a continuous smooth contour line in an upward-downward direction, as shown inFIGS. 1 and2 . While thecap 2 is made from a synthetic resin, such as polypropylene, polyethylene or polystyrene, as with thecontainer body 1, it is formed in a slightly harder structure than thecontainer body 1. - The
cap 2 has a plug protrusion 22 (which is equivalent to "sealing portion" of the present invention) provided on a central region of aninner top surface 20 thereof to protrude downwardly, so that, in the cap-attached state, theplug protrusion 22 is inserted in anozzle hole 14a of thenozzle portion 14 in close contact relation with an inner peripheral surface of thenozzle hole 14a, and thereby thenozzle hole 14a is sealed. - The
cap 2 also has a pair of lockable arms 24 (which is equivalent to "lockable pieces" of the present invention) integrally formed on theinner top surface 20 at respective positions on both sides of theplug protrusion 22. - The
lockable arms 24 are provided to extend along an axial direction of the circulartubular neck portion 12, and formed with a pair of lockingconcave portions 28 in respective distal end regions ofopposing surfaces 26 thereof, so that, in the cap-attached state, thenozzle portion 14 and the circulartubular neck portion 12 are inserted between thelockable arms 24, and alocking protrusion 12a formed on a base end of the circulartubular neck portion 12 is inserted in the lockingconcave portions 28, whereby thecap 2 is locked to thecontainer body 1 through thelockable arms 24, as shown inFIG. 1(a) . - Each of the
opposing surfaces 26 of thelockable arms 24 is formed in a cross-sectionally arc shape corresponding to a shape of an outer peripheral surface of the circulartubular neck portion 12, over the entire region thereof in a longitudinal direction of the lockable arm, and a distance between thelockable arms 24 is set to allow theopposing surfaces 26 to come into contact with the outer peripheral surface of the circulartubular neck portion 12 from laterally opposite sides. Based on this structure, during a cap attaching operation, theplug protrusion 22 and thenozzle hole 14a are aligned with each other, as described later. Thus, in this embodiment, theopposing surfaces 26 are equivalent to "guide surfaces" of the present invention. Each of theopposing surfaces 26 of thelockable arms 24 has a distal end formed in arounded taper 29 to allow thenozzle portion 14 to be smoothly inserted between thelockable arms 24 during the cap attaching operation. - In the container configured as described above, during instillation, the
cap 2 is detached from thecontainer body 1 through an operation of turning thecap 1 from the cap-attached state illustrated inFIG. 1(a) , about the circulartubular neck portion 12 by about 90°. Specifically, when thecap 2 is turned, thecap 2 is brought into riding contact with theshoulder portion 10 of thecontainer body 1, and, along with the riding contact, thecap 2 is pushed upwardly, so that the locked state between the circulartubular neck portion 12 and each of thelockable arms 24 is released. Thus, subsequently, thecap 2 can be detached from thecontainer body 1 along the circulartubular neck portion 12 to perform instillation. - Then, after use, the
cap 2 is attached along the circulartubular neck portion 12 of thecontainer body 1. In this operation, when thecap 2 is manually attached along the circulartubular neck portion 12, thenozzle portion 14 and the circulartubular neck portion 12 are inserted between thelockable arms 24, and theopposing surfaces 26 of thelockable arms 24 come into contact with the outer peripheral surface of the circulartubular neck portion 12 to allow thecap 2 to be guided along the circulartubular neck portion 12, as shown inFIG. 3 . Based on guiding thecap 2 along theopposing surfaces 26 of thelockable arms 24, thenozzle hole 14a is aligned with theplug protrusion 22, so that theplug protrusion 22 is adequately inserted into thenozzle hole 14a. During this operation, each of thelockable arms 24 never comes into contact with the ring-shaped protrusion 15, because the outer diameter dimension of the circulartubular neck portion 12 is set to be greater than the maximum diameter dimension of the nozzle portion 14 (outer diameter dimension of the ring-shaped protrusion 15). - Then, when the
cap 2 is pushed along the circulartubular neck portion 12 to a given dead end position, each of thelockable arms 24 is elastically displaced moderately, so that thelocking protrusion 12a of the circulartubular neck portion 12 is inserted into the lockingconcave portions 28 of thelockable arms 24, and thereby thecap 2 is locked to thecontainer body 1. - As just described, the above container is designed such that, during the cap attaching operation, the
plug protrusion 22 is inserted into thenozzle hole 14a while guiding thecap 2 by causing thelockable arms 24 to come into contact with the circulartubular neck portion 12, so that it is free of the risk of deformation or the like in the nozzle portion due to the cap attaching/detaching operations as in the conventional container designed to guide the nozzle portion along a guide surface provided on the cap while bringing it into contact with the guide surface. Thus, it becomes possible to prevent a disadvantage of deterioration in medical-solution instillation performance due to deformation or the like in thenozzle portion 14. - Particularly, in the above container, the
nozzle portion 14 is provided with theplug protrusion 22 to prevent dripping from thenozzle portion 14 by theplug protrusion 22, and to allow a droplet to be adequately formed in a region of the ring-shaped protrusion 15 during instillation, irrespective of a posture (dripping angle) of thecontainer body 1, to improve the instillation performance, and this instillation performance can be adequately maintained on a long-term basis, because this container can prevent deformation or the like in the nozzle portion 14 (particularly, in the ring-shaped protrusion 15) due to attachment/detachment of thecap 2, as mentioned above. - In addition, the
cap 2 is guided along the circulartubular neck portion 12 under the condition that the opposingsurfaces 26 each having an arc shape corresponding to the circulartubular neck portion 12 is in wide contact with the outer peripheral surface of the circulartubular neck portion 12, so that, during the cap attaching operation, theplug protrusion 22 can be inserted into thenozzle hole 14a while stably guiding thecap 2 along the circulartubular neck portion 12. - Further, with a focus on the
lockable arms 24 as an element unique to the twist cap-type container, the above container is designed to guide thecap 2 along the circulartubular neck portion 12 by using the opposingsurfaces 26 of thelockable arms 24 as a guided surface, which also provides an advantage of being able to obtain the above functions/effects with a rational structure. - Additionally, the above container has an advantage of being able to share the
cap 2 with a container which is different only in shape of thenozzle portion 14. Specifically, in the conventional container designed to guide the nozzle portion by bringing it into contact along a guide surface provided on the cap, it is necessary to provide a guide surface on the side of the cap correspondingly to a shape of the nozzle portion, and thereby a specially-designed cap is required for each of a plurality of types of container bodies each different in outer diameter dimension of the nozzle portion. In contrast, in a structure designed to guide thecap 2 along the circulartubular neck portion 12 as in the container according to the above embodiment, as long as the maximum diameter dimension of thenozzle portion 14 is less than the outer diameter dimension of the circulartubular neck portion 12, thecap 2 can be adequately guided along the circulartubular neck portion 12, irrespective of a specific shape of the nozzle portion. Specifically, thecap 2 can be sharingly used for acontainer body 1 having anozzle portion 14 tapered toward a tip end thereof, as shown inFIG. 4 , or acontainer body 1 having a circulartubular nozzle portion 14 with an approximately constant outer diameter dimension in an axial direction thereof, as shown inFIG. 5 , to obtain the same functions/effects as those in the above embodiment. Particularly, in thecontainer body 1 illustrated inFIG. 4 , thenozzle portion 14 is formed in a shape tapered toward the tip end thereof (taper shape) to reduce a droplet amount and facilitate setting an instillation target. Thus, in the conventional container designed to guide the nozzle portion while bringing it into contact along a guide portion provided on the cap, it is difficult to stably guide the nozzle portion, so that a sufficient guiding effect cannot be obtained, and the intended functions are likely to deteriorate due to deformation or the like in the nozzle portion caused by cap attaching/detaching operations. The container according to the above embodiment can prevent such a disadvantage. Thus, it becomes possible to share thecap 2 between a plurality of types ofcontainer bodies 1 each different only in shape of thenozzle portion 14. This provides an advantage of being able to rationally perform container production, and reduce the burden of stock control. - The aforementioned container is one example of a preferred embodiment of the liquid container according to the present invention, and a specific structure thereof may be appropriately changed without departing from the spirits and scope of the present invention.
- For example, a specific shape of the
nozzle portion 14 may be any suitable shape other thanFIGS. 1 ,4 and5 , as mentioned above. Further, in the above embodiment, the guided surfaces of thecap 2 are adapted to come into contact with the circulartubular neck portion 12 continuously in a circumferential direction thereof, by forming each of the opposingsurfaces 26 of thelockable arms 24 in an arc shape corresponding to the outer peripheral surface of the circulartubular neck portion 12. Alternatively, as shown inFIG. 6 , each of the guided surfaces of thecap 2 may be adapted to come into contact with the circulartubular neck portion 12 intermittently in the circumferential direction thereof. Specifically, thelockable arms 24 may have respective opposingsurfaces 26 each provided with a line-shapedprotrusion 26a protruding therefrom and extending along the circulartubular neck portion 12, in such a manner that the line-shapedprotrusions 26a come into contact with the outer peripheral surface of the circulartubular neck portion 12. In this case, the lockingconcave portion 28 is formed in an intermediate position of each of the line-shapedprotrusions 26a. - In the above embodiment, the
plug protrusion 22 is provided on thecap 2 as the sealing portion of the present invention, wherein theplug protrusion 22 is adapted to be inserted into thenozzle hole 14a to seal thenozzle hole 14a. Alternatively, the sealing portion may be aplug protrusion 22 having a shape adapted to be brought into press contact with an edge region of an opening of thenozzle hole 14a to seal thenozzle hole 14a, instead of the above shape adapted to be fully inserted into thenozzle hole 14a. - In the above embodiment, the pair of
lockable arms 24 arranged in a diametral direction of the circulartubular neck portion 12 are provided on thecap 2 as "lockable pieces" of the present invention. Alternatively, an additional one of the pair oflockable arms 24 may be further provided, wherein the two pairs of, or total four,lockable arms 24, are locked to the circulartubular neck portion 12 from four directions. It is understood that three or more pairs of the lockable pieces (lockable arms 24) may be provided. - In the above embodiment, the circular
tubular neck portion 12 having a cross-sectionally circular shape is provided in thecontainer body 1 as "tubular neck portion" of the present invention. Alternatively, a shape of the tubular neck portion may be a polygonal shape, such as a cross-sectionally hexagonal or octagonal shape. - Although the above embodiment has been described based on an example where the liquid container of the present invention is used as an eye drop container, it is understood that the liquid container of the present invention is usable as a container for a liquid other than an eye drop, such as a container for a nose drop or a contact-lens cleaning solution. The molding materials for the
container body 1 and thecap 2, mentioned in the description of the above embodiment, are an example of a preferred material for an eye drop container, and a specific molding material for thecontainer body 1 or other element may be appropriately selected depending on an intended purpose of the container, etc. - As above, the liquid container according to the present invention is useful as a container for an eye drop, a nose drop, a contact-lens cleaning solution or the like, and suited to adequately maintaining attachability to a container body while preventing a disadvantage such as deformation in a nozzle.
