Description

  The present invention relates to an eyewash container used when an eye is washed with an eyewash.

  Conventionally, as an eyewash container, what is disclosed by patent document 1, for example is known. As shown in FIG. 13 (a), the eye wash container includes a substantially oval pyramid container main body 31 for storing the eye wash and leg portions 32 for allowing the eye wash container 30 to stand independently. It is integrally formed of a material such as an elastomer. In order to wash the eyes using the eyewash container 30, first, an appropriate amount of eyewash solution is stored in the container main body 31, and the eyewash container 30 is pressed against the face so that the face is faced downward. In this state, the tapered squeezed portion 31a formed at the bottom of the container body 31 is pinched and repeatedly squeezed so that the eye surface is immersed in the eyewash while stirring the eyewash in the container body 31. To.

  In the eyewash container 30 that cleans the eyes with the face facing down in this way, the bottom of the container main body 31 has a tapered shape as described above in order to efficiently and appropriately stir an appropriate amount of eyewash. It is indispensable to provide the pressing part 31a. In view of this point, the eye wash container 30 of Patent Document 1 improves the convenience of the eye wash container 30 by providing the leg portion 32. In other words, according to this configuration, even when the eye wash can be performed, it is possible to keep the eye wash liquid in the container main body 31 until the eye wash liquid is accommodated. Since it can be stored in the state of being put in place, there is also an advantage that a place for placement is not selected.

Japanese Patent No. 4432075

  Although the conventional eye wash container 30 disclosed in Patent Document 1 has the advantage of being able to stand on its own, it has the following drawbacks. In other words, the eye wash container 30 is provided with leg portions 32 at positions on both sides of the squeezing portion 31a, specifically, at the positions on the eyes and the corners of the eye with the squeezing portion 31a interposed therebetween. Therefore, at the time of washing the face, it is necessary to squeeze the squeezing part 31a with the fingertips inevitably and squeeze the squeezing part 31a with the fingertips facing the face as shown in FIG. 13 (b). In this case, the arm holding the eyewash container 30 is pulled toward the trunk, the side is tightened, and the squeezing operation is performed with the elbow placed in front of the chest. Is not good. In particular, when the eyewash container 30 is held in the dominant hand and the eye on the side different from the dominant hand is washed, or when the eyewash container 30 is washed with a hand different from the dominant hand, the operation becomes more difficult. . In addition, it is not only difficult for female users who have extended nails to pick the compressed portion 31a in a stable manner, but sometimes the operability is improved, for example, the hand slips when the hand is wet. There was room.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an eye container that is easier to use and excellent in stability while maintaining a self-supporting configuration.

In order to solve the above problems, an eyewash container according to the present invention includes a bottomed cylindrical container body, a leg for allowing the eyewash container to stand independently in a posture in which the container body opens upward, and A connecting portion that connects the leg portion and the container body portion, the container body portion forming an eyewash portion having an elliptical cross section including the opening, a bottom portion of the container body portion, and the washing body. A pressure part that is deformed by receiving a pressing operation force along the short axis direction of the eye part and stirs the eyewash contained in the container body part, and the leg part is the pressure part in the short axis direction. The side surface of the leg portion and the side surface of the pressing portion are connected via the connecting portion that is provided on both sides of the portion so as to be separated from the pressing portion and is elastically deformable and extends in the short axis direction. And the squeezing from the outside of the leg part through the connecting part. In which is provided to be input to the squeezing operation force.

  In the eye wash using this eye wash container, for example, using the thumb and forefinger, the leg is picked from the outside at positions on both sides in the short axis direction of the eye wash and pressure (squeezing operation force) is applied to the leg. Then, the said pressing part is squeezed (squeezed) through the said leg part and a connection part. According to this configuration, instead of directly pinching the squeezed part with a fingertip as in a conventional eyewash container, as described above, the leg part is picked and the squeezed part is squeezed via the leg part and the connecting part. There is no longer any restriction on the legs with respect to the position and width (area) when picking the container. In other words, the degree of freedom of how to hold the eyewash container is improved. Therefore, it is easier to use while allowing the eyewash container to stand on its own, as compared to the conventional eyewash container that always needs to pick the eyewash container only with the fingertip and perform the squeezing operation with the fingertip facing the face. . In addition, since the eyewash container can be picked without directing the fingertip toward the face, more stable eyewashing is possible.

  In the eyewash container, it is preferable that the container main body, the leg, and the connecting portion are integrally formed of the same material that can be elastically deformed.

  According to this configuration, it is possible to efficiently produce an eyewash container using one kind of material, and thus there is an advantage that productivity is improved.

  Moreover, in this eyewash container, the said leg part is the cylinder shape which surrounds the said pressing part, and is connected with the side surface of the said pressing part via the said connection part in the position of the both sides of the said pressing part in the said short axis direction. It is suitable.

  According to this configuration, it is possible to more stably place the device in a self-supporting posture on a flat surface such as a table. Moreover, the restoring force of the leg part elastically deformed by pressing operation becomes larger. For this reason, the return force acts on the squeezing part via the connecting part, so that the squeezing part deformed with the squeezing operation can be returned more quickly. Therefore, it becomes possible to wash the eye while efficiently stirring the eye wash by the pressing operation. There is also an advantage that the degree of freedom of the material forming the eyewash container is improved. That is, it becomes possible to return the squeezed portion in the compressed state only by the restoring force of the leg by increasing the restoring force of the leg. For example, it is conceivable that the wall thickness of the compressed portion is formed very thin, and the compressed portion in the compressed state is mainly restored only by the restoring force of the leg portion. In this case, as long as the leg portion can be elastically deformed, the compressed portion itself does not necessarily have elasticity. For this reason, it is possible to form an eyewash container by widely using a resin material such as polyethylene as well as an elastomer having excellent elasticity and flexibility.

  Further, in the eyewash container, the leg portion is formed in a skirt shape whose outer surface is continuous with the outer surface of the eyewash portion, and is the position of the connecting portion in the circumferential direction of the leg portion. And it is suitable to provide the opening part in the position of the said eyewash part side rather than the said connection part.

  According to this configuration, since the entire side surface of the eyewash container is substantially continuous, the eyewash container can be easily held and used more easily. Moreover, since the opening is provided at the position of the connecting portion in the circumferential direction of the leg portion and at the position on the eye wash portion side, the squeezing operation is performed while the leg portion is formed in the skirt shape as described above. The eyewash part is restrained from being deformed by being pulled outward in the short axis direction at the time (pressurization). Therefore, during the eyewash, the eyewash is prevented from leaking from between the face and the eyewash container due to the deformation.

  In addition, although the said connection part should just be a shape which can transmit appropriately the operation force at the time of pressing operation from a leg part to a pressing part, for example, the said connection part is toward the said pressing part side from the said leg part side. More preferably, it is tapered.

  According to this configuration, it is possible to efficiently transmit the squeezing operation force applied to the leg portion from the leg portion to the squeezing portion, thereby deforming the squeezing portion.

  As described above, according to the eyewash container of the present invention, the degree of freedom in how to hold the eyewash container can be increased. Therefore, it is easier to use and more stable while allowing the eyewash container to be self-supporting, compared to conventional eyewash containers that always require the fingertips to be picked and the fingertips to face the face. Can be washed.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  1 to 7 show an eyewash container 1A according to the first embodiment. FIG. 1 is a perspective view, FIG. 2 is a plan view, FIG. 3 is a front view, and FIG. 4 is a side view. 5 is a bottom view, and FIGS. 6 and 7 are cross-sectional views, each showing an eyewash container 1A.

  As shown in these drawings, an eyewash container 1A includes a bottomed cylindrical container main body 10 that stores an eyewash liquid, and a leg 20 for self-supporting in an attitude in which the opening of the container main body 10 faces upward. And a connecting portion 25 that connects the leg portion 20 and the container body portion 10, and the container body portion 10, the leg portion 20, and the connecting portion 25 are integrally formed of a flexible material that can be elastically deformed. is there. The material forming the eyewash container 1A will be described later.

  As shown in FIGS. 6 and 7, the container main body 10 forms an eyewash part 11 including an opening of the container main body part 10 and a bottom part of the container main body part 10 connected to the eyewash part 11. It is comprised from the taper-shaped pressing part 12 to do. The eye wash unit 11 is a part for immersing the eye surface in an eye wash to wash the eye, and the squeezing unit 12 performs a squeeze operation by the user to stir the eye wash in the eye wash unit 11. Part.

  The eye wash part 11 has an elliptic frustum shape that is narrowed downward. Specifically, the eye wash section 11 has an oval face contact portion 11a capable of enclosing the eye, and an elliptical cross-section peripheral wall portion 11b extending downward from the face contact portion 11a in a funnel shape. And a shelf-like portion 11c extending inward from the lower end portion of the peripheral wall portion. And the said pressing part 12 is connected inside this shelf-shaped part 11c. The pressing part 12 has a tapered shape toward the lower side. The pressing part 12 has a pair of flat side wall parts 14 that are elongated in the major axis direction of the eyewash part 11 and correspond to each other in the minor axis direction of the eyewash part 11.

  In addition, the said eyewash part 11 is the dimension from the center position of the pressing part 12 to the edge part (right end of FIG. 2) of the one side in the said major axis direction to the edge part (left edge of FIG. 2) of the other side. It is formed longer than the dimension. That is, at the time of eye washing, the eye is placed in the state where the pressing part 12 is placed at the center of the eye by touching the eye wash container 1A so that the end on one side is located on the outer corner of the eye and the other side is located on the front of the eye. It can be covered properly.

  As shown in FIG. 5, the leg portion 20 is formed in a substantially cylindrical shape that continuously surrounds the compressed portion 12 over its entire circumference, and as shown in FIG. 6, The outer side surface is formed in a skirt shape connected to the lower end portion of the peripheral wall portion 11 b so that the outer surface is continuous with the outer surface of the peripheral wall portion 11 b of the eye wash portion 11. The lower end surface of the leg portion 20 is flush with the bottom portion of the pressing portion 12 or protrudes downward from the bottom portion. Thereby, 1 A of eyewash containers can stand by making the lower end surface of the leg part 20 ground (FIGS. 6 and 7).

  The leg portion 20 is connected to the pressing portion 12 of the container main body portion 10 through the two connecting portions 25. Specifically, as shown in FIG. 5, the connecting portion 25 is interposed between the inner side surface of the leg portion 20 and the side wall portion 14 of the squeezing portion 12, thereby shortening the eye wash portion 11. In the axial direction, the compressed portion 12 and the leg portion 20 are connected to each other at positions on both sides of the compressed portion 12.

  The connecting portion 25 has a T-shaped cross section including a first plate-like portion 26a extending along the circumferential direction of the leg portion 20 and a second plate-like portion 26b extending downward from the center thereof. The first plate-like portion 26a is set so that its width dimension gradually decreases from the leg portion 20 side toward the pressing portion 12 side, whereby the connecting portion 25 has a tapered shape as a whole. (See FIG. 5).

  An opening 22 is formed at a position above each connecting portion 25 in the leg portion 20, whereby the leg portion 20 is located at the position of the connecting portion 25 in the circumferential direction of the leg portion 20. It is separated from the eye wash part 11.

  1, 2, 6, and 7, reference numeral 16 denotes a locking portion for locking the eye wash container 1 </ b> A to an unillustrated bottle that stores the eye wash solution. That is, the bottle in which the cleaning liquid before use is accommodated includes a bottle body having a spout at the top and a cap that closes the spout, and the eye wash so that the cap is interposed inside the container body 10. When the container 1A is put on the cap, the locking portion 16 engages with the locked portion of the cap, and the eyewash container 1A is held on the top of the bottle.

  Next, a procedure for performing eyewash using the above-described eyewash container 1A will be described.

  When performing eyewash using the eyewash container 1A, first, an appropriate amount of eyewash is stored in the container body 10 from the bottle. At this time, the eye wash container 1A may be held with one hand, and the eye wash may be poured into the eye wash container 1A while holding the bottle with the other hand, but the eye wash container 1A is self-supporting by grounding the leg portion 20 as described above. Therefore, by placing the eyewash container 1A on the table and pouring the eyewash liquid, an appropriate amount of eyewash liquid can be stably and accurately accommodated in the eyewash container 1A. In addition, although illustration is abbreviate | omitted, the scale which shows the appropriate amount of eyewash is formed in the surrounding wall part 11b of the said eyewash part 11 of the container main-body part 10, Therefore, a user uses this scale as a standard. An appropriate amount of eyewash can be stored in the eyewash container 1A.

  After the eyewash is stored in the eyewash container 1A, the face is turned downward, the eyewash container 1A is oriented so that the major axis direction of the eyewash part 11 and the left-right direction of the face coincide with each other, and the eyewash part 11 The eyewash container 1A is pressed against the face so as to cover it. In this case, for example, as shown in FIG. 8, the eyewash container 1 </ b> A is pressed against the face in a state where the leg portion 20 is picked along the thumb and the index finger in a direction parallel to the long axis direction of the eyewash portion 11. And in this state, it presses so that the leg part 20 may be repeatedly crushed with a thumb and an index finger, and, thereby, the said pressing part 12 is squeezed through the leg part 20 and the connection part 25 (squeeze). When the squeezing part 12 is squeezed in this way, the eyewash in the squeezing part 12 is pushed out to the eyewashing part 11 and the eyewash is stirred. Therefore, the eye is washed by immersing the eye surface in this eyewash. be able to.

  The eyewash container 1A as described above does not directly squeeze and squeeze the squeezing part with a fingertip as in the conventional eyewashing container, but as described above, the leg part 20 is picked and the leg part 20 and the connecting part 25 are interposed. The squeezing unit 12 is squeezed. According to such a configuration, the position and width (area) of picking up the eyewash container 1A are not restricted by the legs as in the conventional eyewash container. That is, the degree of freedom in how to hold the eyewash container 1A is high. Therefore, as shown in FIG. 8, the leg part 20 can be picked along the thumb and the index finger in a direction parallel to the major axis direction of the eyewash part 11, and the leg part 20 can be squeezed in this state. . According to such a method of picking the legs 20, the eye wash container 1 </ b> A can be picked using not only the fingertip but also a wide range such as the abdomen and joint of the finger. In addition, the arm holding the eyewash container 1A can be squeezed in an easy posture with its elbows stretched and wide open. In addition, the female user can reliably perform the squeezing operation by picking the eyewash container 1A without worrying about the length of the nails. In addition, since the eyewash container can be picked without directing the fingertip toward the face, more stable eyewashing is possible.

  Therefore, according to the eyewash container 1A, the eyewash container is always picked only by the fingertip, and further, the pressing operation is performed with the fingertip facing the face. However, it is easier to use and can wash the eyes stably.

  In particular, the eyewash container 1A has a substantially cylindrical shape in which the leg portion 20 continuously surrounds the entire leg portion 20 as shown in FIG. It is possible to make it. Therefore, the eyewash container 1A can be made to stand more stably.

  Moreover, according to such a substantially cylindrical leg part 20, the restoring force of the leg part 20 elastically deformed by the squeezing operation becomes relatively large. Therefore, when this return force acts on the squeezing part 12 via the connection part 25, it becomes possible to return the squeezing part 12 which deform | transformed with squeezing operation more rapidly. Therefore, there is also an advantage that the eye wash can be performed while efficiently stirring the eye wash by the pressing operation. Furthermore, there is an advantage that the degree of freedom of the material forming the eyewash container is improved. That is, by increasing the return force of the leg portion 20, the compressed portion 12 in the compressed state can be returned only by the return force of the leg portion 20. For example, it is conceivable that the wall thickness of the compressed portion 12 is formed to be very thin, and the compressed portion 12 in the compressed state is returned only by the restoring force of the leg portion 20. In such a case, if the leg part 20 can be elastically deformed, the pressing part 12 itself does not necessarily need to have elasticity. Therefore, it is possible to form an eyewash container by widely using a resin material such as polyethylene as well as a material excellent in elastic force and flexibility such as an elastomer described later.

  Moreover, since the leg part 20 is formed in the skirt shape connected with the lower end part of the said surrounding wall part 11b so that the outer side surface may continue to the outer side surface of the said surrounding wall part 11b of the eye washing part 11, an eyewash container There is almost no unevenness on the side surface of 1A. According to such a configuration, ease of holding is not affected by the size of the finger or the like, and it is easy to use regardless of gender.

  In addition, the opening portion 22 is formed above the connecting portion 25 in the leg portion 20, and the eye wash portion 11 and the leg portion 20 are separated at a position above the connecting portion 25. Can be prevented from leaking from the eyewash container 1A at the time of eyewashing. That is, when the opening 22 is not present, the eyewash part 11 is pulled during the squeezing operation (pressurization) and the eyewash part 11 (face contact part 11a) is deformed so as to open in the minor axis direction. As a result, a gap may be formed between the face and the eyewash container 1A, causing liquid leakage. However, according to the configuration of the eyewash container 1A in which the opening portion 22 is formed in the leg portion 20, the eyewashing portion 11 and the leg portion 20 are separated from each other at a position above the connecting portion 25. The eyewash part 11 is hardly pulled at the time (pressurization), and the deformation of the eyewash part 11 (face contact part 11a) as described above is suppressed. Therefore, the liquid leakage from the eyewash container 1A due to the deformation of the eyewash part 11 can be effectively suppressed.

  Further, since the opening 22 is formed, for example, as shown in FIG. 8, when the eye wash container 1 </ b> A is picked, a part of the surface of the finger enters the opening 22, and The engagement becomes better. That is, an anti-slip effect can be obtained. Therefore, according to the eyewash container 1A, there is an advantage that the eyewash container 1A can be picked and washed more stably.

  9 to 12 show an eyewash container 1B according to the second embodiment. FIG. 9 is a front view, FIG. 10 is a side view, and FIGS. 11 and 12 are cross-sectional views. Show. The plan view and the bottom view of the eyewash container 1B according to the second embodiment are the same as those of the first embodiment (FIGS. 2 and 5).

  As shown in the figure, the eyewash container 1B of the second embodiment is different from the eyewash container 1A of the first embodiment in that the upper end of the leg 20 is completely separated from the eyewash part 11. To do. That is, in the eyewash container 1B, the leg part 20 is connected to the container body part 10 only by the connecting part 25.

  According to this configuration, since the leg part 20 is separated from the eyewash part 11, there is no possibility that the eyewash part 11 is pulled by the squeezing operation and the eyewash part 11 (face contact part 11a) is deformed. No. Therefore, there is an advantage that liquid leakage from the eyewash container 1A due to the deformation of the eyewash part 11 (face contact part 11a) with the pressing operation can be reliably prevented.

  The elastically deformable flexible material for forming the above-described eyewash containers 1A and 1B is not particularly limited as long as it is a material having elastic force and flexibility, but has moldability, chemical resistance, and heat resistance. It is preferable that it has no odor. Moreover, you may provide antibacterial activity as needed. Furthermore, in consideration of safety, it is preferable that it conforms to the 2011 Ministry of Health, Labor and Welfare Notification No. 65 and the 16th revised Japanese Pharmacopoeia General Test Law.

  Specific examples include thermoplastic resins, silicone resins, thermoplastic elastomers, natural rubber, urethane rubber, and the like, or combinations thereof. In the case of a thermoplastic resin, for example, in the case of an olefin resin, it is known that moldability is improved by combining a thermoplastic elastomer or a hydrogenated styrene thermoplastic elastomer.

  As thermoplastic elastomer, moldability, chemical resistance, stain resistance, environment, cost, etc., as appropriate from styrene, olefin, urethane, polyester, polyamide, fluorine, vinyl chloride, etc. However, styrene type and olefin type are preferable. These may be used alone, or may be used by combining a plurality, for example, by laminating.

  Specifically, Tuftec (registered trademark) series H1052 and H1053 manufactured by Asahi Kasei Co., Ltd. Septon (registered trademark) series CJ001, CJ002, CJ101, CJ102 manufactured by Kuraray Co., Ltd. Sirlink (registered trademark) series 3140, 3160, 4155, 4165 (olefin type) and the like manufactured by the company are included.

  The hardness is 50 to 80 as measured by JIS K6253 (durometer type A), and the tensile strength and elongation are 5 to 20 MPa and 300% tensile stress as measured by JIS K6253 (No. 3 dumbbell tensile speed 500 mm / min). The standard is a range of about 1.5 to 5 MPa.

  As mentioned above, although embodiment of the eyewash container of this invention was described, the eyewash containers 1A and 1B mentioned above are the illustrations of the eyewash container of this invention, Comprising: The specific structure is the range which does not deviate from the summary of this invention. It can be changed as appropriate. For example, the following configuration may be employed.

  In the said embodiment, although the leg part 20 is formed in the cylindrical shape so that the pressing part 12 may be surrounded continuously, the leg part 20 of the pressing part 12 is at least in the short-axis direction of the eyewash part 11. What is necessary is just to be provided in both sides. Therefore, the leg part 20 may be divided at a plurality of positions in the circumferential direction so as to intermittently surround the compressed part 12.

  Moreover, in the said embodiment, although the connection part 25 has a T-shaped cross section, it is not restricted to this, A cross-shaped cross-section, a cross-section U-shape, and a cross-section cylinder shape may be sufficient. In short, any shape that can transmit the squeezing operation force to the squeezing portion 12 without deformation as much as possible when the squeezing operation force is applied to the leg portion 20 may be used. Therefore, as long as the squeezing operation force applied to the leg part 20 can be appropriately transmitted to the squeezing part 12, it may be a solid shaft or plate.

  Further, the eyewash containers 1A and 1B may be ones in which anti-slip is formed on the surface of the leg portion 20 by embossing or the like. According to this configuration, the eye wash containers 1A and 1B can be picked more stably, and the eye wash containers 1A and 1B can be used more easily.
