ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a combination vessel of a cap type sealing tool and a bottle portion having a specifically shaped external wall, and a combination vessel of a cap type sealing tool including a cap portion and a ring portion, and a bottle portion. More particularly, the present invention relates to a combination vessel of a cap type sealing tool in which a lower surface of the cap portion and an upper surface of the ring portion are coupled to each other through a plurality of bridge parts which can easily be broken, and a bottle portion having a specifically shaped external wall. Each bridge part couples the lower surface of the cap portion to the upper surface of the ring portion, and is broken via rotation of the cap portion in a cap portion opening (unsealing) direction. The ring portion is always slid downwardly while a sliding protrusion provided in a lower stage area of an internal wall contacts, by pressure, an upward spread zone formed on an external wall of a neck area of the bottle portion.
In addition, the present invention relates to a combination vessel of a cap type sealing tool and a bottle portion without any possibility that a contact lens dropped from holding structure by mistake might adhere to a bottom surface of a bottle area, because of formation of specific concavo-convex shapes on a bottom of an internal wall of the bottle portion. A suspending member extends from a bottom (back) surface of a top plate part of the cap portion, and a mutual relationship among vertical convexities to block an opening turn (e.g. non-return type vertical protrusions, non-return type vertical trenches, non-return type ratchet) is established to realize a “temporary mounting” state in order to prevent the holding structure, for maintaining the contact lens or the like, from being deformed. In addition, the “temporary mounting” state is very preferable when supplying the vessel to customers who are to supply contents at their end, wherein a vessel in the “temporary mounting” state means that the vessel can be opened without breakage of the bridge parts unless the cap portion is further rotated.
Furthermore, the present invention relates to a combination vessel of a cap type sealing tool and a bottle portion which can continuously achieve a cap portion closing state, from which the cap portion is capable of easily being opened while also maintaining airtightness of a filled solution when the cap type sealing tool is turned in a cap portion closing direction beyond the temporary mounting state.
2. Description of the Related Art
A distribution bottle portion (which is used on a distribution route) of an RGP contact lens to be used as a bottle portion constituting a combination vessel according to the present invention is a combination vessel mainly constituted by three members, namely, a cap portion, a suspending tool (holding member) extending from a lower surface of a top plate part of the cap portion, and a bottle portion.
A conventional coupling seal tool (virgin cap) of this kind is a structure obtained by coupling a cap portion, screwed to an outer periphery of a neck area of a bottle portion, and a ring portion through a plurality of thin bridges extended from a lower end surface of the cap portion. When the cap portion is usually turned in a closing direction during cap portion opening, the following non-return (check) function results. Specifically, a projection, to block an opening turn of the cap portion (downward projection), provided on the lower end surface of the cap portion is engaged with a projection, to block the opening turn of the cap portion (upward projection), provided on the upper surface of the ring portion to turn the ring portion. Also, a vertical projection, to block an opening turn of the cap portion (ratchet), provided on an internal wall surface of the ring portion is engaged with a vertical projection (ratchet) provided on an external wall surface of a neck area of the bottle portion to block rotation of the ring portion.
Consequently, in addition to the function to block the opening turn of the cap portion, the bridge is broken by a downward pressing force (push-down force) applied when the lower projection is positioned over the upper projection positioned on the right side thereof so that the ring portion is brought down and only the separated cap portion can be turned. There has been an advantage in that it is possible to determine whether a cap portion has already been opened or not by looking at the bridge and determining if it has been broken.
The foregoing proposals of this kind include the following examples. Japanese Laid-Open Utility Model Publication No. 7-21556 (1995):
This proposal relates to a “prevention against an incorrect opening of cap”
1
formed by a bottomed cylindrical cap body
2
and a ring
3
adjacent to a lower end surface thereof. A sawtooth type pressing projection
7
is provided extending downwardly at two portions on the lower end surface, while a sawtooth pressure receiving projection
10
is provided extending upwardly from an upper surface of the ring
3
. Next, the lower end surface of the cap body
2
is coupled to the upper surface of the ring
3
through several coupling pieces
4
.
Furthermore, the sawtooth type pressing projection
7
is engaged with a projection of the ring
3
when a screw, provided on an internal wall of the cap body
2
, is turned in a closing direction, and is not engaged with the projection of the ring
3
when the cap
2
is turned in an opening direction. In addition, eight vertical convexities
13
are provided extending inwardly from an inner periphery of a small diameter portion
3
a
of the ring
3
. The vertical convexities
13
are not engaged with a sawtooth type vertical projection
25
provided on an external wall of a bottle member
20
when the cap
2
is turned in a closing direction, and are engaged with the sawtooth type vertical projection
25
when the cap
2
is turned in an opening direction.
Accordingly, when the cap
2
is once turned slightly in the closing direction, it is stopped in such a stage that a vertical convexity
13
provided on the internal wall thereof is positioned over the vertical projection
25
provided on the external wall of the bottle member
20
, and is then turned in an opening direction such that the ring
3
positioned in a lower stage is turned together in the opening direction. As a result, the cap
1
can be removed from a neck portion of the bottle member
20
so that a bottle can be opened.
Referring to normal downward movement and predetermined position, fixation of ring portion
12
after opening of the bottle with such a structure so that the cap
1
, to be part of the combination vessel according to the present invention, is mounted on an upward spread zone of the bottle member
20
; however, a prevention system for preventing any incorrect opening of the cap
1
has been neither disclosed nor suggested. In other words, it is necessary to provide a press-interposing function through formation of a taper area (provision of a sliding protrusion
12
uc
or the like) in a lower stage of an internal wall of ring portion
12
, and to carry out cooperation thereof with an upward spread (downward taper) area provided on an external wall of a neck area
2
m
on the bottle portion side in order to achieve normal downward movement of the ring portion
12
after bridge part
13
is broken according to the present invention. However, this aspect has been neither disclosed nor suggested in Japanese Laid-Open Utility Model Publication No. 7-21556 (1195).
Japanese Laid-Open Patent Publication No. 9-58720 (1997):
This proposal provides an improvement in a bottle member (which will be referred to as a “bottle”)
1
. The bottle member
1
has a thread
2
protruded only in an upper stage portion of an external wall of a neck area thereof. A middle stage portion of the external wall is smooth, a lower stage portion of the external wall is provided with a plurality of sawtooth
