Description

Eye drops container

The present invention relates to eye drops containers.

Conventionally, for example, a container described in Patent Document 1 is known as an eye drop container. The eye liquid container includes: a flat container body containing a chemical liquid; a nozzle attached to the container body; and a cover detachably attached to the container body so as to cover the nozzle. The method of use is as known. The cap is removed so that the tip of the nozzle faces downward, and the container body is gently pressed to drip the drug solution from the tip of the nozzle.

In the eye liquid container, the nozzle is embedded in a cylindrical mouth portion formed in the container body in a liquid-tight state. Further, when the cover is attached, the shaft-shaped projection formed on the cover is inserted into the injection port at the tip end of the nozzle, thereby blocking the injection port.

In the conventional eye liquid container described above, since the projection of the lid is inserted into the discharge port at the tip end of the nozzle, if there is an error in the size of the cap, the nozzle may be removed from the cartridge together with the cap. The neck of the mouth was pulled out. This problem can be eliminated by making the fitting of the nozzle and the tubular neck portion tighter. However, in this case, there is a problem in that it is difficult to assemble the nozzle to the container body, the assembly property of the eye drop container is deteriorated, and cracking (cracking) occurs in the tubular neck portion.

In addition, in the eye drop container, it is known that the nozzle and the tube are based From the viewpoint of the liquid tightness of the neck and the neck and the good assembly of the above, the container body is formed of a hard synthetic resin material (for example, polyethylene terephthalate), and the nozzle is made of a soft synthetic resin. A structure formed of a material such as polyethylene. However, a soft synthetic resin material may adsorb the components of the eye drops, and therefore, it is necessary to suppress the adsorption of the components, or the material of the nozzles to be selected may be limited. Therefore, there is a problem that it is difficult to achieve both the quality stability of the eye drops and the above-described liquid tightness and assemblability.

In addition, in recent years, it has been researched to be able to drop eye drops in a comfortable posture, or to improve the visibility of the nozzle position when dropping eye drops, and to meet a variety of eye drops containers for user needs. From the viewpoint of pursuing easy dropping of eye drops, for example, a structure in which a discharge port is formed on the side of the nozzle so that the eye liquid container is not directed downward can be used, or the nozzle position is from the center of the container. The structure in which the portion is deviated toward the outside. Since the eye drop container having the so-called shaped nozzle has a restriction on the orientation of the nozzle injection port of the container body, there is a problem that assembly failure is easily induced.

In addition, in recent years, for example, in order to prevent the makeup of the eyeliner or the like from being removed, it is required to reduce the diameter of the nozzle to make the eye drop container having a small amount of dripping. In the manufacturing process of the eye liquid container, in the nozzle storage device before the assembly and the nozzle supply device in the manufacturing process, the nozzles are fitted in a bead connection state, and the supply delay of the nozzle or the nozzle cannot be used. . The nozzle that becomes such a beaded connection state is usually discarded, and thus there is a problem that the yield is poor.

(First embodiment)

Fig. 1 (a) and (b) show the eye drop container of the present invention in a sectional view. As shown in Fig. 1 (a) and (b), the eye liquid container 1A (hereinafter simply referred to as the container 1A) is a so-called twist cap type container, and the container body 2 is detachably attached to the container 2 The lid 3 of the container body 2.

As shown in Fig. 2(a), the container body 2 is provided with a container body 10 With the cover member 16.

The container body 10 has a substantially rectangular parallelepiped liquid accommodating portion 11 which is slightly elongated and flat in the vertical direction, a shoulder portion 12 connected to the upper end portion of the liquid accommodating portion 11, and a center portion of the shoulder portion 12 and The tubular neck portion 13 having a circular cross section, the liquid accommodating portion 11, the shoulder portion 12, and the cylindrical mouth portion 13 are integrally formed of a transparent or translucent resin material. In this example, the container body 10 is made of, for example, a polyester resin such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, or polybutylene naphthalate, or poly A synthetic resin material such as aromatic ester, polypropylene or polystyrene is molded.

The cover member 16 is molded in such a manner that the nozzle portion 16a and the holding portion 16b (corresponding to other portions of the present invention) are integrally molded from a different resin material (for example, two-color molding). Specifically, the nozzle portion 16a is molded, for example, of low-density polyethylene, and the holding portion 16b is molded of, for example, polypropylene. In addition to the low-density polyethylene, a soft synthetic resin such as a linear low-density polyethylene, a high-density polyethylene, or an elastomer can be used as the material of the nozzle portion 16a, and the material of the holding portion 16b is other than polypropylene. It can be applied to synthetic resins such as low density polyethylene, linear low density polyethylene, high density polyethylene, and polystyrene.

The holding portion 16b includes a top wall portion 20 having a contour substantially equal to the contour of the liquid containing portion 11 of the container body 10, an outer wall portion 22 hanging from the outer peripheral portion of the top wall portion 20, and the top wall A pair of locking pieces 24 (the locking portions of the present invention) in which the central portion of the portion 20 is suspended from the lower surface thereof.

Further, as shown in FIGS. 1(a) and 1(b), the cover member 16 is locked to the container body 10 such that the holding portion 16b covers the tubular mouth portion 13.

In detail, the pair of locking pieces 24 of the holding portion 16b are located radially outward of the cylindrical mouth portion 13 of the container body 10, and extend in the axial direction of the cylindrical mouth portion 13. The opposing faces of the locking pieces 24 have a circular arc shape corresponding to the outer peripheral surface of the tubular neck portion 13 as a whole, and a locking groove 24a is formed in each of the distal end portions (lower end portions). On the other hand, the cylindrical neck portion 13 has an annular projection 13a (corresponding to the locking projection of the present invention) which protrudes outward in the radial direction on the outer peripheral surface of the tubular neck portion 13 and the base portion. That is, as shown in Fig. 1(a), the cylindrical neck portion 13 of the container body 10 is inserted between the respective locking pieces 24, and the projections 13a of the cylindrical mouth portion 13 are engaged with the respective locking portions. The locking groove 24a of the piece 24, whereby the cover member 16 is locked to the container body 10.

As described above, in the state in which the cover member 16 is locked to the container body 10, as shown in Fig. 1(a), the lower end portion of the outer wall portion 22 of the holding portion 16b is fitted to the step portion formed along the outer edge of the shoulder portion 12. 12a. Thereby, the outer surface of the cover member 16 (holding portion 16b) is substantially flush with the outer surface of the liquid containing portion 11 of the container body 10, and the outer shape of the container body 2 which is substantially continuous in the vertical direction is formed.

The nozzle portion 16a has a cylindrical insertion portion 17a extending downward from the top wall portion 20, a flange portion 17b connected to the upper end of the insertion portion 17a, and an upper surface from the upper surface of the top wall portion 20. A protruding nozzle body 17c. The eye drops are dripped from the tip of the nozzle body 17c.

In a state where the cover member 16 is locked to the container body 10, as shown in Fig. 1(a), the insertion portion 17a of the nozzle portion 16a is fitted into the cylindrical neck portion 13 of the container body 10, and the flange The portion 17b abuts against the upper end portion of the tubular mouth portion 13. Thereby, the nozzle portion 16a is attached to the cylindrical neck portion in a liquid-tight state. 13.

Further, the nozzle portion 16a and the holding portion 16b are integrally molded in a state where the flange portion 17b of the nozzle portion 16a is covered by the top wall portion 20 of the holding portion 16b from the outside (the nozzle body 17c side). According to this configuration, the strength of the extraction of the cover member 16 by the nozzle portion 16a (the upward pulling strength) can be improved.

The cover 3 is formed in a dome shape having a cover portion 30 and a peripheral wall portion 32 formed along the outer circumference of the cover portion 30, and is attached to the container body 2 so as to cover the upper portion of the cover member 16.

In the lid 3, a cylindrical plug portion 34 is protruded from the lower surface of the covering portion 30, and when the lid 3 is attached to the container body 2, the plug portion 34 is fitted into the nozzle portion 16a (the nozzle body 17c). The outlet is opened, whereby the outlet is closed. Further, when the lid 3 is attached to the container body 2 as described above, the hook portion 32a formed on the inner side surface (the inner side surface of the peripheral wall portion 32) of the lid 3 is engaged with the container body 2 as shown in Fig. 1(b). The locking protrusion 23 is formed on the outer side of the cover member 16 (holding portion 16b), whereby the cover 3 is locked to the container body 10.

The container 1A is used in the same manner as the conventional eye drop container. In other words, when the eye drops are dropped, the lid 3 is rotated by about 90° around the nozzle body 17c from the lid mounting state indicated by the two-dot chain line in Fig. 1(a), whereby the lid 3 is removed from the container. Body 2 is removed. In other words, when the cover 3 is rotated, the cover 3 jumps up onto the top wall portion 20 of the cover member 16 (holding portion 16b), and with the jump-up operation, the cover 3 is pushed up, and the hook portions 32a and The locked state between the locking projections 23 is released. Therefore, after the cover 3 is detached from the container body 2, the eye drops can be dripped. When the eye drops are dropped, the tip end of the nozzle portion 16a faces downward, and the container body 10 is lightly pressed to drip the eye drops from the nozzle portion 16a. use Thereafter, the lid 3 is placed on the container body 2, and the lid 3 is pressed toward the liquid storage portion 11 to engage the hook portion 32a with the locking projection 23, thereby maintaining the mounting state with respect to the lid 3 of the container body 2. . Therefore, the container 1A can be stored in this state.

According to the container 1A as described above, there are the following advantages.

First, according to the container 1A, the nozzle portion 16a and the holding portion 16b are integrally molded (two-color molding). Therefore, even when an external force acts on the nozzle portion 16a when the cover 3 is removed, the nozzle portion 16a can be prevented from the container body 10 ( The tubular mouth neck 13) is pulled out. In other words, in the case where the nozzle body 17c is tightly fitted to the plug portion 34 due to the dimensional error of the plug portion 34 of the cover 3 or the nozzle portion 16a (the nozzle body 17c), a strong external force in the pull-out direction acts on The nozzle portion 16a. However, even in this case, according to the container 1A, the nozzle portion 16a and the holding portion 16b are integrally molded, and the cover member 16 (the holding portion 16b) is locked to the container body 10 by the locking piece 24 (the cylindrical opening) The neck portion 13) can also prevent the nozzle portion 16a from being pulled out from the container body 10. In particular, the flange portion 17b of the nozzle portion 16a is integrally molded with the holding portion 16b in a state of being covered by the holding portion 16b (the top wall portion 20), whereby the pulling strength is improved. Thereby, the nozzle portion 16a can be prevented from being pulled out from the cover member 16 alone. Further, according to the container 1A, since the pulling force (external force) acts on the locking piece 24 as described above, in order to prevent the nozzle portion 16a from being pulled out, it is not necessary to strictly require the tube with respect to the cylindrical neck portion 13 The fitting tolerance of the mouth portion 16a (insertion portion 17a) can set the fitting tolerance as loosely as possible within a range in which liquid tightness is ensured. Therefore, according to the container 1A, the nozzle portion 16a can be prevented from being inadvertently pulled out from the tubular neck portion 13 of the container body 10, and the operation of assembling the cover member 16 to the container body 10 can be easily performed. That is, the nozzle portion 16a (insertion portion 17a) is inserted into the tubular neck portion 13 industry.

Further, according to the container 1A, for example, as shown in FIG. 2(b), the cover member 16 can mold the nozzle portion 16a and the holding portion 16b using a resin material of a different color. Therefore, according to the container 1A in which the nozzle portion 16a and the holding portion 16b are different in color as described above, it is possible to improve the visibility of the injection port when dropping the eye liquid, and it is advantageous in use.

(Second embodiment)

(a) and (b) are the cross-sectional views of the eye liquid container 1B (hereinafter simply referred to as the container 1B) according to the second embodiment. The container 1B of the second embodiment is a modification of the container 1A of the first embodiment. Therefore, the same portions as those of the container 1A are denoted by the same reference numerals and will not be described. The main description of the container 1A of the first embodiment will be described below. difference.

The container 1B is most different from the container 1A of the first embodiment in that a cylindrical seal portion 21 projecting downward from the lower surface of the top wall portion 20 is formed in the holding portion 16b of the cover member 16. The sealing portion 21 surrounds the nozzle portion 16a at a position between the locking piece 24 and the nozzle portion 16a. The sealing portion 21 is in close contact with the outer circumferential surface of the cylindrical mouth portion 13 of the container body 10, whereby the holding portion 16b (the cover member 16) and the cylindrical mouth portion 13 (the container body 10) are sealed.

According to the container 1B of the second embodiment as described above, in addition to the advantages of the container 1A of the first embodiment, it is possible to use polyethylene terephthalate (PET) having a low adsorption property of the preparation component, and a pair of polyethylene. The polyester resin such as butyl phthalate (PBT) constitutes the nozzle portion 16a, and has an advantage of contributing to improvement in quality stability of the chemical liquid (eye drops). In other words, from the viewpoint of quality stability, the nozzle portion 16a and the container book which are in contact with the chemical liquid in the container body 10 Similarly to the body 10, it is preferably composed of a polyester resin such as PET having a low adsorption property of the formulation component. However, polyester resins such as PET have low elasticity. Therefore, from the viewpoint of preventing liquid leakage prevention, a nozzle portion is formed by using a relatively flexible polyethylene (PE) or polypropylene (PP) to ensure a nozzle portion. Sealing property with the container body (cylindrical neck). On the other hand, according to the container 1B of the second embodiment, as described above, the holding portion 16b and the container body 10 are sealed by the sealing portion 21 formed in the holding portion 16b (the lid main portion 40) (the tubular neck portion) 13) to prevent liquid leakage. Therefore, for example, the nozzle portion 16a is formed of a polyester resin such as PET similar to the container body 10 by molding the holding portion 16b in the cover member 16 with PE or PP, and has the advantage that liquid leakage can be prevented and liquid leakage can be prevented. The formulation component is prevented from being adsorbed to the nozzle portion 16a to improve the quality stability of the chemical solution.

(Third embodiment)

(a) and (b) are the cross-sectional views of the eye liquid container 1C (hereinafter simply referred to as the container 1C) according to the third embodiment. The container 1C of the third embodiment is a modification of the container 1B of the second embodiment. Therefore, the same portions as those of the container 1B are denoted by the same reference numerals, and the description thereof will be omitted. The main description of the container 1B of the second embodiment will be described below. difference.

The container 1C is roughly configured to change the container structure of the container 1B of the second embodiment from the twisted lid type to the hinge lid type. Specifically, the container 1C is provided with a hinge cover 15 instead of the lid 3 of the container 1B and the cover member 16.

The hinge cover 15 has a cover body portion 40 (corresponding to the cover member of the present invention) including a nozzle portion 16a and a holding portion 16b and fixed to an upper end portion of the container body 10; and an injection port for opening and closing the nozzle portion 16a. Cover 18 (corresponding to the cover of the present invention); and a hinge connecting the cover 18 to the cover body 40 Part 19. In other words, the cover body portion 40 corresponds to the cover member 16 of the container 1B, and the cover 18 corresponds to the cover 3 of the container 1B.

The hinge cover 15 is formed by integrally forming (i.e., two-color molding) the nozzle portion 16a and other portions from a different resin material. Specifically, the nozzle portion 16a is molded, for example, of low-density polyethylene, and the other portions (the holding portion 16b, the cover 18, and the hinge portion 19) are molded of, for example, polypropylene. In addition to the low-density polyethylene, a soft synthetic resin such as a linear low-density polyethylene, a high-density polyethylene, a polypropylene, or an elastomer can be used as the material of the nozzle portion 16a as the other portion (holding portion). The material of the 16b, the cover 18, and the hinge portion 19) may be a synthetic resin such as polystyrene other than polypropylene.

The cover 18 is connected to the holding portion 16b by the hinge portion 19 so as to be able to be in the closed position (the position indicated by the two-dot chain line in Fig. 4(a)) and the open position (the solid line of Fig. 4(a) The rocking displacement is performed between the positions shown therein, wherein the closed position is a position overlapping the top wall portion 20 of the cover body portion 40 (holding portion 16b) to cover the nozzle portion 16a, and the open position is from the position The closed position is deployed to the side of the lid body portion 40 to open the position of the nozzle outlet of the nozzle portion 16a. Further, when the cover 18 is closed (disposed in the closed position), the plug portion 34 of the cover 18 is fitted into the injection port of the nozzle portion 16a (the nozzle body 17c), whereby the injection port is closed. Further, the hook portion 32a provided in the cover 18 is engaged with the locking protrusion 23 (not shown) provided in the holding portion 16a, whereby the cover 18 is held at the closed position.

Although not shown in detail in the drawings, the hinge portion 19 is composed of two types of hinge portions having different shapes, and the cover portion is formed at an acute angle with respect to the angle between the top wall portion 20 and the cover 18 of the holding portion 16b. 18 force it to the closed position, In a state in which the angle formed by the top wall portion 20 and the cover 18 is an obtuse angle, the cover 18 is biased to be in an open position. According to this configuration, the cover 18 can be held at the open position when the eye drops are dropped.

According to the container 1C of the third embodiment as described above, since the container body 10 and the hinge cover 15 are configured as two members, the number of components can be reduced as compared with the container 1B of the second embodiment. This has the advantage of being able to improve assembly and reduce cost. Further, as described above, the container 1C of the third embodiment is configured to change the container structure of the container 1B of the second embodiment from a twisted lid type to a hinge lid type, and the other configuration is the same as that of the container 1B of the second embodiment. Therefore, in the container 1C of the third embodiment, the same effects as those of the container 1B of the second embodiment can be obtained.

(Fourth embodiment)

(a) and (b) are the cross-sectional views of the eye liquid container 1D (hereinafter simply referred to as the container 1D) according to the fourth embodiment. The container 1D of the fourth embodiment is a modification of the container 1B of the second embodiment. Therefore, the same portions as those of the container 1B are denoted by the same reference numerals, and the description thereof will be omitted. The main description of the container 1B of the second embodiment will be described below. difference.

In the container 1B (Fig. 3(a)) of the second embodiment, the sealing portion 21 projecting downward from the lower surface of the holding portion 16b (the top wall portion 20) is formed, and in the container 1D of the fourth embodiment. Such a sealing portion 21 is not provided. Instead, as shown in Fig. 5 (a) and (b), the center of the top wall portion 20 has a cylindrical shape extending upward, and a tube is disposed inside the cylindrical portion (referred to as the cylindrical portion 20a). The mouth portion 16a is provided with a locking piece 24 on the outer side of the cylindrical portion 20a. That is, in the container 1D, the cylindrical portion 20a of the top wall portion 20 is in close contact with the container body The outer peripheral surface of the cylindrical neck portion 13 of 10 is thereby sealed between the holding portion 16b (cover member 16) and the container body 10. In summary, in the container 1D, the cylindrical portion 20a corresponds to the sealing portion of the present invention.

Further, in the container 1D of the fourth embodiment, the nozzle opening of the nozzle portion 16a (the nozzle body 17c) is not provided on the top surface of the nozzle body 17c, but is provided on the substantially side surface in the lateral direction. In other words, the container 1D makes it possible to drop the eye drops in a convenient posture in which the container 1D is oriented in the lateral direction (the container 1D does not need to face directly below). In particular, in the container 1D, as shown in Fig. 6, the nozzle body 17c is disposed at a center (container center) from the insertion portion 17a in the short-side direction of the horizontal section of the container (the left-right direction in Fig. 6). The position of one side (left side in the figure). The nozzle outlet of the nozzle body 17c opens toward the outside (in the sixth drawing, leftward) on one side of the nozzle body 17c. Thereby, the container body 10 is caught by the both sides of the short side direction and inclined, so that the injection port can be as close as possible to the eye and the eye drops can be dripped.

Further, as shown in Fig. 6, the plug portion 34 of the lid 3 has a cylindrical shape, and when the lid 3 is attached to the container body 2, the tip end of the nozzle portion 16a (the nozzle body 17c) is fitted inside the plug portion 34. Thereby, the injection port of the nozzle portion 16a is closed. In particular, in the container 1D, since the nozzle body 17c is biased to one side from the center (container center) of the insertion portion 17a as described above, two plug portions 34 are arranged in the short-side direction of the cover 3. Thereby, the lid 3 is attached to the container body 2 so that the container body 2 and the lid 3 are aligned, and the lid 3 can be attached without paying attention to the position of the nozzle body 17c, and the usability is improved.

Further, a spherical portion 34a is formed inside the plug portion 34 of the cover 3, and when the cover 3 is attached to the container body 2, the nozzle portion 16a (nozzle body 17c) The top end is inserted inside the plug portion 34, and the spherical portion 34a is in close contact with the periphery of the injection port including the nozzle body 17c, whereby the injection port is closed.

According to the container 1D of the fourth embodiment, there is an advantage in that the assembly property of the eye drop container of the type which drops the eye drops in the lateral direction is improved. In other words, in the conventional eye liquid container of the type in which the eye drops are laterally dropped, it is necessary to attach the nozzle portion to the container body so that the injection port faces in a specific direction, and as a result, the direction restriction of the nozzle portion is required, and as a result, A special process is required, and there is a problem that the manufacturing process is complicated. However, according to the container 1D including the cover member 16 in which the nozzle portion 16a and the holding portion 16b are integrally molded (two-color molding), when the cover member 16 is assembled to the container body 10, the orientation of the nozzle portion 16a is naturally determined, and therefore, In the manufacturing process of the container 1D, a special process for restricting the direction of the nozzle portion 16a is not required. Therefore, according to the container 1D, in the eye drop container of the type which can drop the eye liquid in the lateral direction, it is possible to prevent the occurrence of assembly failure without paying special attention. Therefore, there is an advantage that the assembly property of the container 1D can be improved.
