[Prior Art] Previously, as a container for eye drops or the like, there is generally known a container which includes a container body having a nozzle and a cover attachable to and detachable from the container body, The drug solution is dripped from the tip of the nozzle by removing the cap with the tip of the nozzle facing down and gently squeezing the container body. In particular, the so-called twist-capped liquid container as described in Patent Document 1 has been widely used as a container for eye drops, etc. 'The twist-capped liquid container has a fastening arm on the inner circumferential surface of the cover. 'The cover is attached to the container body by engaging the fastening arm with the fastening protrusion formed on the container body, and on the other hand, the Φ buckle of the fastening arm is released by twisting the cover relative to the container body. In the assembled state, remove the cover. Further, since containers such as eye drops are carried in a large amount, it is necessary to reliably prevent liquid from leaking from the nozzle. To this end, in the container of Patent Document 1, a plug protrusion (sealing portion) is provided at the top of the lid, and the inspection protrusion is inserted into the nozzle opening to prevent liquid leakage, and a guide portion is provided around the plug protrusion. The nozzle and the plug projection are positioned so that the plug projection can be smoothly inserted into the nozzle opening during the mounting operation of the cover. However, in the container described in Patent Document 1, when the lid is attached, the nozzle portion is brought into contact with the guide portion provided on the lid to guide the lead 2014-10413-PF 3 200951032. During the loading and unloading operation, the nozzle will be deformed, etc., and the formation of droplets will be affected. In particular, the container is formed such that an annular projection is formed on the outer circumference of the nozzle to prevent liquid from leaking from the nozzle and the liquid droplet operability is improved regardless of the posture (dropping angle) of the container body. For example, in Patent Document 2), since the tip end portion of the annular projection is guided along the guide portion of the cover, if the cover is repeatedly attached or detached, the annular projection is deformed and the liquid leakage prevention function and the droplet formation function are provided. Caused obstacles. Further, since only the tip end portion of the annular projection comes into contact therewith along the guide portion of the cover, there is a problem that it is difficult to stably guide the nozzle along the guide portion when the cover mounting operation is performed. Therefore, it is necessary to improve the above problems with a reasonable composition. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-196417. When the cover is well guided, it is attached to the container body, and on the other hand, problems such as deformation of the nozzle can be prevented. The container for liquid of the present invention comprises: a container body having a cylindrical neck portion and having a nozzle portion integral with the tip end of the cylindrical neck portion; and a topped cylindrical cover having a seal for sealing the nozzle opening And the outer diameter of the cylindrical body of the container body is larger than the above-mentioned 2014-10413-PF 4 200951032 喷嘴 nozzle part, so as to cover the nozzle part and the cylindrical neck portion The maximum diameter dimension is also provided on the outer peripheral surface of the cylindrical neck portion and the hooking projection for the cover, and the lid is provided on the inner top portion along the neck portion. a pair of engaging pieces extending in the diametrical direction of the cylindrical mouth-and-neck portion, and the cylindrical mouth portion is attached to the bar body in the axial direction of the cylindrical neck portion Inserted into each of the fastening pieces, the above-mentioned fastening projections are inserted into the recesses formed on the opposing faces of the fastening pieces to fasten the cover to the container body, and the fastening surfaces of the fastening pieces are slid The guide surface is in contact with the outer peripheral surface of the tubular neck portion when the cover is attached to the container body, thereby guiding the nozzle port along the tubular neck portion so that the nozzle port corresponds to the seal portion The above cover. According to the liquid container, when the female cover is attached along the axial direction of the cylindrical neck portion of the container body, the nozzle and the cylindrical mouth neck are inserted between a pair of fastening pieces provided at the inner top of the cover, and The guide is placed in contact with the outer peripheral surface of the cylindrical π neck portion based on the guide of each of the engaging pieces, and the cover is guided in the axial direction of the cylindrical neck portion. The nozzle opening is positioned relative to the sealing portion by guiding the cover along the guiding faces of the respective fastening tabs. Then, when the cover is inserted into the predetermined end position in the axial direction of the tubular neck portion, the engaging projections of the tubular neck portion are inserted into the engaging recesses formed on the opposing faces of the respective engaging pieces. As a result, the lid is engaged with the container body. In other words, according to the liquid container, the nozzle portion is not guided by the guide portion provided on the cover as described above, so that the deformation of the nozzle caused by the contact can be prevented. . Further, since the guide surface of the tubular neck portion is integrally provided on the engaging piece for engaging the lid to the container body, the above-described action can be obtained with a reasonable configuration. ^ As a specific configuration, the guide surface of each of the engaging pieces may be shaped to correspond to the cross-sectional shape of the outer peripheral surface in such a manner as to continuously contact the peripheral surface of the cylindrical neck and neck material in the circumferential direction of the outer peripheral surface & may be formed so as to intermittently contact the outer peripheral surface of the cylindrical neck portion in the circumferential direction of the outer circumference (four). Further, the above-described configuration is particularly useful for a liquid container in which an annular projection as the maximum diameter portion is formed on the outer circumference of the nozzle portion. In other words, by forming an annular projection on the outer circumference of the nozzle portion, it is possible to prevent liquid from leaking from the nozzle portion, and it is possible to form droplets well regardless of the posture of the container body (dropping angle), thereby improving dripping operation. According to the configuration described above, since the nozzle portion is not in contact with the guide portion provided on the cover when the cover is attached, the deformation of the annular projection is prevented. As a result, J has a negative period and maintains the above functions well. [Embodiment] Fig. 1 and Fig. 2 show a main part of a container for a liquid according to the present invention. The liquid container (hereinafter simply referred to as a six-piece) shown in Figs. 1 and 2 is a so-called twist-capped container.

The nozzle portion 14 is molded by a soft synthetic resin such as low density polyethylene, linear low density polyethylene, high density polyethylene, or polypropylene. As shown in Fig. 1(b), the nozzle portion 14 is provided with an annular projection 15 on the outer circumference, and has a narrow narrow portion on the proximal end side (lower side) of the annular projection 15. That is, 'the annular protrusion 15 is used to prevent the liquid from leaking from the mouth portion 14, and in the case of the eye drop, the posture of the container body 1 (dropping angle) is good in the portion of the annular projection 15 A droplet is formed. Further, the outer diameter of the cylindrical neck portion 12 is set larger than the maximum diameter of the nozzle portion 14 (in the present embodiment, the outer diameter of the annular projection 15), whereby the cover 2 is attached to the container body. In the state of 1 (hereinafter simply referred to as the cover mounting state), a gap is formed between the fastening arm 24 and the nozzle portion 14 in the lid 2, and the lid 2 and the annular projection 15 are brought into a non-contact state. 2014-10413-PF 7 200951032 As shown in Fig. 1 (in the first figure (1), for convenience of explanation, only a part of the cover 2 is shown by a solid line), and as shown in Fig. 2, it is formed in a topped cylindrical shape to cover the shoulder. The upper portion of the portion 10 and the cover 2 are attached to the container body 1. As shown in the above figure, the side surface of the body i and the side surface of the cover 2 form a continuous and smooth outline in the vertical direction. The lid 2 is formed of, for example, polypropylene, a synthetic resin such as ethylene or polystyrene, and the texture of the lid 2 is slightly harder than that of the container body. A plug protrusion 22 (corresponding to the sealing portion of the present invention) that protrudes downward is provided at a central portion of the inner top surface 20 of the cover 2, and the plug projection 22 is inserted into the nozzle opening Ua of the nozzle portion 14 in a state where the cover is attached. The nozzle opening 14a is sealed in close contact with the inner peripheral surface of the nozzle opening i4a. On the inner top surface 20 of the cover 2, a fastening arm 24 (corresponding to the fastening piece of the present invention) is integrally formed, and the fastening arm 24 is located on the left and right sides of the plug protrusion 22 via the plug protrusion 22 . The fastening arms 24 extend in the axial direction of the cylindrical neck portion 12, and the engaging recesses 28' are formed on the opposing faces 26 of the front ends of the arms in the cap mounting state.

The body is removed. That is, after the lid 2 is rotated, the lid 2 rests on the shoulder 1 of the container body i, whereby the lid 2 is pushed upward, so that the fastening arms 24 and the cylindrical neck portion 12 are buckled. The state is released. Thereafter, the lid 2 is detached from the container body 1 along the cylindrical σ neck portion 12, whereby the eye can be made. Cylindrical opening of 1 On the other hand, after use, the cover 2 is attached to the neck portion 12 along the neck portion 12 of the container body and the opposing faces 26 of the cylindrical neck portion 24. At this time, if the operation is performed along the cylindrical casing 2, as shown in Fig. 3, the nozzle portion n portion 12 is inserted between the two fastening arms 24, and the fastening arm and the cylindrical neck portion are engaged. The outer peripheral surface of 12 is in contact, whereby the lid 2 is guided along the cylindrical neck portion. Thus, along the opposing direction of each of the fastening arms 24: the guide cover 2' positions the nozzle π 14a with respect to the plug projection 22 so that the inspection projection 22 is well inserted into the nozzle opening i4a. In this case, the container is set such that the outer diameter of the cylindrical neck portion 12 is larger than the maximum diameter of the nozzle portion (the outer diameter of the annular projection 15), so the fastening arm 24 does not The meeting 2014-10413-PF 9 200951032 is in contact with the annular protrusion 15. When the predetermined end is reached, the engagement of the cylindrical opening 24 is concave. If the position of the cover 2 is pressed along the cylindrical neck portion 2, the fastening arm 24 is elastically displaced moderately. The engaging projection 12a of the 12 is inserted into each of the fastening arm portions 28, whereby the cover 2 is engaged with the container body 1. Thus, in the above-described container, since the hooking arms 22 are brought into contact with the cylindrical neck portion 12 at the time of the cover, the lid 2 is guided while the cap 2 is inserted into the nozzle opening 14a. As in the prior art, the nozzle portion is brought into contact with the guide surface provided on the cover to enter the (four) guide container. "The nozzle portion may be deformed by the attachment and detachment of the cover." Therefore, for example, the problem of impairing the dripping performance of the drug due to deformation of the nozzle portion 14 t or the like can be prevented. In particular, the container is provided with an annular projection & in the nozzle portion 14, thereby preventing the liquid from leaking from the nozzle portion 14 by the annular projection 15, and regardless of the posture (dropping angle) of the container body 1 at the time of eye drop, The droplets are formed well in the portion of the annular projections 15, and the operability at the time of eyedrops is improved. Therefore, as described above, the container can prevent the deformation of the nozzle portion 14 (especially the annular projection 15) caused by the attachment and detachment of the cover 2, and the above-mentioned eye drop can be maintained for a long time because of A'. The operability of the time.

Therefore, there is also an advantage that a reasonable constitution can be utilized to obtain the above-described effects. Further, the use of the above container has the advantage that the lid 2 can be shared with other containers having only the shape of the nozzle portion 14. That is, in the previous container in which the nozzle portion is guided in contact with the guide surface provided on the cover, it is necessary to provide a guide surface corresponding to the shape of the nozzle portion on the cover side, and therefore, the outer portion of the nozzle portion For the container body with different diameters, a separate cover is required. On the other hand, when the lid 2 is guided along the cylindrical neck portion 12 as in the container of the above embodiment, the maximum diameter of the nozzle portion 14 is smaller than the outer diameter of the cylindrical neck portion 12. The size allows the cover 2 to be guided well along the tube-shaped neck portion 12 regardless of the specific shape of the nozzle portion 14. Specifically, the volume of the nozzle portion 14 having the tapered end shown in FIG. 4 or the nozzle portion having the outer diameter of the cylindrical portion in the axial direction is substantially constant. Since the lid 2 can be advantageously used for the container body 1 of 14, the same effects as those of the above embodiment can be obtained. In particular, in the container body i shown in Fig. 4, in order to control the amount of liquid droplets and to easily set the drop target, the nozzle portion is set to a tapered shape (tapered shape), and if the nozzle portion is used: the guide portion is used. In the previous container that was brought into contact with the guide, it is difficult to stably guide the nozzle portion, so that a sufficient guiding effect cannot be obtained, and the function of the nozzle portion due to the attachment and detachment of the cover causes the function to be '4 Å S Further, with the container of the above embodiment, it is possible to prevent a plurality of different shapes of 2014-1Ο413-ΡΓ 11 200951032 14 from having the following advantages: such a problem can be combined. Therefore, the cover 2 can be shared between the nozzle-only container bodies 1, and as a result, the containers can be manufactured rationally, and the burden of inventory management can be alleviated. Further, the above-described container is a preferred embodiment of the liquid container of the present invention, and the specific configuration thereof can be appropriately changed without departing from the spirit and scope of the invention. For example, as described above, the specific shape of the nozzle portion 14 may be a shape other than the shapes shown in the i-th, fourth, and fifth figures. Further, in the embodiment, the opposing surface 26 of the fastening arm 24 is formed in an arc shape corresponding to the shape of the outer circumferential surface of the cylindrical neck portion 12, whereby the guided surface of the cover 2 is formed in a circle The structure in which the tubular neck portion 12 is continuously contacted in the circumferential direction thereof. However, as shown in Fig. 6, for example, the guided surface of the lid 2 may be configured to be non-circular with the cylindrical neck portion 12 Structure that is in continuous contact. Specifically, the protrusions extending along the cylindrical π neck portion 81 may be protruded from the opposite faces 26 of the fastening arms 24, and the protrusions may also be combined with the cylindrical neck portion 12. The composition of the outer peripheral surface contact. In this case, the engaging recess 28 is formed in the middle portion of the ridge 26a. Further, in the embodiment, the cap 2 is provided with a plug projection 22 as a seal portion of the present invention, and the inspection projection 22 is inserted into the nozzle opening 14a of the nozzle portion 14, thereby 'sealing the nozzle opening 14a' but the above In addition to the shape in which the sealing portion is fully inserted into the nozzle opening, the sealing portion 22 may be pressed against the opening edge portion of the nozzle opening 14a to seal the nozzle opening 14a. Further, in the embodiment, the cover 2 is provided with a cylindrical neck portion.
