Description

  The present invention relates to a liquid container provided with a liquid injection port for pouring out the stored liquid while a space capable of storing the liquid is formed inside.

  2. Description of the Related Art Conventionally, containers that store liquid seasonings and the like that can dispense several drops of liquid so as to appropriately adjust the total amount of liquid to be dispensed have been studied.

  For example, Patent Document 1 discloses a container that includes a container body that is open upward and a space in which liquid can be stored is formed inside, and a cap that closes the opening of the container body. In addition, a liquid injection hole for discharging liquid is formed, and the cap is provided with a blocking portion for blocking a part of the liquid flowing through the passage from the opening of the container body to the liquid injection hole. Have been disclosed.

JP 2009-89913 A

  However, in the container of Patent Document 1, the amount of liquid toward the liquid injection hole changes without being blocked by the damming portion according to the amount of liquid stored in the container body and the inclination of the container body. Therefore, it is necessary to adjust the inclination of the container body in accordance with the amount of liquid, and there is a problem that the operability is not sufficiently high. Specifically, when the amount of liquid stored in the container main body is small, even if the container main body is tilted greatly, the amount of liquid that goes over the blocking portion and goes to the liquid injection hole can be suppressed to a small amount. When the amount of liquid stored in the main body is large, if the container main body is tilted greatly, a large amount of liquid passes over the damming portion and is poured out toward the liquid injection hole.

  An object of the present invention is to provide a liquid container capable of appropriately pouring a small amount of liquid and having high operability.

  In order to solve the above-mentioned problems, the present invention is a liquid container having a liquid-storing port for pouring out the stored liquid while a space capable of storing the liquid is formed inside. Provided on the outer wall of the liquid container and provided with a pressing portion that can be elastically deformed toward the inside of the liquid container to change the volume of the inner space of the liquid container, and the pressing portion is at the center thereof. A first pressing portion provided; and a second pressing portion surrounding the first pressing portion. The second pressing portion has a thickness larger than the thickness of the first pressing portion, and has an inner circumference. There is provided a liquid container characterized in that the side portion has a shape that is thicker than the outer peripheral portion.

  According to this liquid container, the volume of the inner space of the liquid container can be changed by an amount corresponding to the amount of deformation of the pressing part by pressing the pressing part to deform it. Therefore, only the liquid corresponding to the volume change of the liquid container corresponding to the deformation amount of the pressing portion can be poured out regardless of the amount of liquid stored in the container body or the inclination of the container. Accordingly, by a simple operation of pressing the pressing portion, the liquid can be appropriately poured out by a fixed amount and by a small amount.

  And in this liquid container, the 1st press part is provided in the center of a press part, Furthermore, the 2nd press part which has a thickness larger than the thickness of a 1st press part is provided in the circumference | surroundings, A press part There are provided portions where the pressing forces required for deformation are different from each other. Therefore, by adjusting the pressing force applied to the pressing portion according to the application or the like, the amount of liquid dispensed can be easily changed step by step, and the convenience can be further enhanced.

  Specifically, according to this liquid container, only the first pressing portion having a small thickness can be first deformed by pressing the center of the pressing portion, that is, the first pressing portion with a relatively weak force. Therefore, in this case, only the amount of liquid corresponding to the deformation amount of the first pressing portion can be poured out. On the other hand, by pressing the first pressing portion with a relatively strong force, the second pressing portion having a large thickness can be deformed in addition to the first pressing portion. In this case, A relatively large amount of liquid corresponding to the total deformation amount with the second pressing portion can be poured out.

  In particular, in this liquid container, the thickness on the outer peripheral side of the second pressing portion is set to be relatively small. Therefore, the deformation of the second pressing portion can be promoted by the outer peripheral portion. Accordingly, even when both the first pressing portion and the second pressing portion are deformed, the operability can be more reliably improved without requiring excessive force.

  The said structure WHEREIN: The said 2nd press part is provided in the inner peripheral side, the 1st thick part by which the whole thickness was made substantially constant, and the whole thickness provided in the outer peripheral side of the said 1st thick part. It is preferable to include a second thick portion that is smaller than the thickness of the first thick portion and substantially constant.

  According to this configuration, the second pressing portion can be deformed while being bent at the boundary portion between the first thick portion and the second thick portion, and the thickness of the second pressing portion is increased to facilitate the deformation thereof. be able to.

  The said structure WHEREIN: It is preferable that the width | variety of the said 2nd thick part is set smaller than the width | variety of the said 1st thick part.

  If it does in this way, a deformation | transformation of only the 1st press part can be more reliably implement | achieved by suppressing a deformation | transformation of the part which is located in an inner peripheral side among thick parts, and supports a 1st press part.

  The said structure WHEREIN: It is preferable that a said 1st press part has a shape which bulges toward the outer side of the said liquid container.

  If it does in this way, a user can recognize easily the central part of the press part which is the 1st press part and should be pressed. Moreover, this can be easily deformed by crushing the first pressing portion.

  The said structure WHEREIN: The said 2nd press part has a shape which bulges toward the outer side of the said liquid container, and the said 1st press part is further outside the said liquid container rather than the outer surface of the said 2nd press part. It preferably has a shape that bulges toward the surface.

  If it does in this way, the whole 1st press part and the 2nd press part can be changed more easily.

  The said structure WHEREIN: It is preferable that the said 1st press part has a circular shape seeing from the direction orthogonal to the said outer side wall in which the said 1st press part is provided.

  If it does in this way, the pressing force applied to the 1st press part can be uniformly given to the 1st press part and the whole press part, and these can be changed appropriately. For this reason, it is possible to suppress the change in the amount of liquid dispensed by changing the position of the pressing portion where the pressing operation is performed.

  In the above configuration, a container body having a storage chamber that opens upward to store liquid and formed inside, and a lid that is detachably attached to the container body and closes the opening of the container body. The pressing part is preferably provided on the upper surface of the lid.

  If it does in this way, a liquid can be easily inject | poured in a container main body by removing a cover body. Further, since the pressing portion is formed on the upper surface of the lid, the pressing portion can be easily operated when the liquid container is gripped and the liquid is poured out while being tilted, and the operability can be improved. .

  According to the present invention, a small amount of liquid can be appropriately poured out and the operability can be improved.

The lid 20 has a ceiling-like substantially cylindrical shape having a top plate portion 21 extending in a substantially horizontal direction, and a space 20a that opens downward is formed inside thereof. As shown in FIG. 3, the inner space 20 a of the lid body 20 and the storage chamber 10 c of the container body 10 communicate with each other when the lid body 20 is attached to the container body 10. In the present embodiment, the entire lid 20 is integrally formed of the same material, and is made of, for example, a synthetic resin such as silicone having a predetermined hardness (for example, 50 degrees) between 40 and 70 degrees. Become. In the following description of the lid 20, the radial direction of the lid 20 is simply referred to as the radial direction.

  A part of the outer peripheral wall 24 of the lid 20 protrudes radially outward at an upper portion thereof, and a flange 22 that protrudes radially outward is formed at an upper portion of the lid 20. As shown in FIG. 4, the flange portion 22 has a substantially triangular shape in a plan view, and as shown in FIG. 3, is inclined upward toward the radially outer side.

  As shown in FIG. 3, a liquid injection passage 22a extending in the radial direction is formed inside the collar portion 22, and the inner space 20a of the lid 20 communicates with the liquid injection passage 22a. The main chamber 21a is located below the top plate 21. The liquid injection passage 22a is opened at the outer end surface 22b in the radial direction of the flange 22, and a liquid injection port 22c for pouring out the liquid stored inside the liquid container 1 to the outside is provided on the end surface 22b. Is formed. That is, the liquid stored in the storage chamber 10c of the container body 10 is poured out from the liquid injection port 22c through the main chamber 21a and the liquid injection passage 22a. The liquid injection passage 22a is inclined upward toward the radially outer side.

  In the present embodiment, a protruding portion 23 that protrudes outward in the radial direction is provided at the radially outer end of the flange portion 22, and a liquid injection port 22 c is formed on the end surface 22 b of the protruding portion 23. . This protrusion 23 has a cylindrical shape with a very small diameter, and in this embodiment, when such a protrusion 23 is provided, liquid is poured out from the liquid injection port 22c. Further, the occurrence of dripping around the liquid injection port 22c is suppressed. In the present embodiment, the flow passage area of the liquid injection passage 22a is reduced in the vicinity of the liquid injection port 22c.

  The upper wall of the lid 20, that is, the portion of the top plate portion 21 that constitutes the outer wall of the liquid container 1 has a circular shape in the center (as viewed from the direction orthogonal to the top plate portion 21). And the dome-shaped press part 30 which bulges upwards is provided. The pressing portion 30 is thinner than the other portions of the top plate portion 21 and constitutes the top surface of the main chamber 21a. That is, the outer peripheral wall 24 extends downward from the outer peripheral portion of the top plate portion 21 with respect to the pressing portion 30, and the main chamber 21 a is defined by the lower surface of the pressing portion 30 and the inner peripheral surface of the outer peripheral wall 24. ing. In the present embodiment, a portion of the top plate portion 21 near the outer peripheral edge of the pressing portion 30 also bulges upward.

  The pressing portion 30 is thin as described above, and can be easily deformed downward by pressing the upper surface 30a by the user. The pressing portion 30 is elastically restored by releasing the pressing operation, and can be elastically deformed downward, that is, toward the inside of the liquid container 1.

  The pressing portion 30 includes a first pressing portion 32 that is located in the center and has a circular shape in plan view, and a ring-shaped second pressing portion 34 that surrounds the entire circumference of the first pressing portion 32. In the present embodiment, the first pressing portion 32 bulges further upward from the second pressing portion 34.

  As shown in FIG. 5 etc., the thickness of the first pressing portion 32 is a constant value t1 throughout.

  On the other hand, the thickness of the 2nd press part 34 is set so that it may become so small that the radial direction outer side. In this embodiment, the thickness of the 2nd press part 34 is set to two steps, and the 2nd press part 34 is located in the inner peripheral side, the 1st thick part 34a with large thickness, and the outer peripheral side. It consists of the 2nd thick part 34b which is located and has thickness smaller than the 1st compact part 34a.

  Specifically, a step portion 34c is formed on the lower surface of the second pressing portion 34 such that the radially outer portion is positioned higher than the radially inner portion, and the diameter of the step portion 34c is larger than that of the step portion 34c. The thickness of the inner portion in the direction is set to a constant value t2 to form the first thick portion 34a, and the thickness of the outer portion in the radial direction from the step portion 34c is set to a constant value t3 smaller than the value t2. Thus, the second thick part 34b is formed.

  As shown in FIG. 4, the first thick part 34 a and the second thick part 34 b extend over the entire circumference of the second pressing part 34. In the present embodiment, the width dimension L1 of the first thick part 34a is set larger than the dimension L2 in the width direction of the second thick part 34b. In addition, the width | variety, ie, radial dimension, of these 1st thick parts 34a and 2nd thick parts 34b is constant over the perimeter.

  Here, the thickness t2 of the first thick part 34a and the thickness t3 of the second thick part 34b are both set larger than the thickness t1 of the first pressing part 32, and the thickness of the second pressing part 34 is It is larger than the thickness of the first pressing part 32. And the thickness of the press part 30 is the thinnest in the 1st press part 32 located in the center, is the thickest in the 1st thick part 34a of the 2nd press part 34 located in the outer peripheral side, and also on the outer peripheral side. The second thick portion 34b of the second pressing portion 34 that is positioned is set to have an intermediate value.

  The thicknesses t1, t2, and t3 of the portions 32, 34a, and 34b may be set as appropriate according to the type of material that constitutes the parts. For example, t1, t2, and t3 are 1: 3.5: 1.8. Set to degree. Further, the radius r of the first pressing portion 32 and the radial dimensions L1 and L2 of the thick portions 34a and 34b may be appropriately set according to the type of material constituting these. However, t1, t2, and t3 are set to about 0.4 to 1.4 mm, about 2.7 to 3.7 mm, and about 1.1 to 2.1 mm, respectively, and r, L1, and L2 are set to 5. If it is set to about 5 to 6.5 mm, about 4 to 6 mm, or about 2 to 3 mm, when pressing the pressing portion 30 to pour out the liquid and changing the extraction amount as described later, It has been found that good operability can be obtained and is preferably set to these values.

  At the lower end of the lid 20, that is, at the lower end of the outer peripheral wall 24 of the lid 20, a concave portion 24 a that is recessed radially outward is formed on the inner peripheral surface thereof. The concave portion 24 a is formed over the entire circumference of the outer peripheral wall 24 of the lid portion 20.

  The recess 24a is a portion that engages with the locking projection 17 of the container body 10, and as shown in FIG. 3, the lid 20 is inserted into the recess 20a by inserting the locking projection 17 into the recess 24a. It is locked to.

  In the present embodiment, a groove 24b that is recessed upward is formed at a position above the recess 24a in the outer peripheral wall 24, and the inner peripheral wall of the groove 24b is configured with the lid 20 attached to the container body 10. A portion 24 c to be inserted is inserted into the opening 10 a of the container body 10. In addition, the outer peripheral wall 24 of the lid portion 20 is placed on the upper surface of the step portion 13 of the container body 10 in a state where the lid body 20 is mounted on the container body 10, and the outer surface of the lid portion 20 and the container body 10. The outer surface of the surface is continuous with the surface.

(2) Liquid pouring procedure The liquid container 1 configured as described above is tilted and is the center portion of the pressing portion 30, that is, the center portion of the first pressing portion 32, and swells upward most. By pressing the part, the liquid is poured out from the liquid injection port 22c. And according to the pressing force applied to the 1st press part 32, the extraction amount of this liquid is changed in steps.

  This will be specifically described with reference to FIGS. FIG. 6 shows a state when the first pressing portion 32 is pressed with a relatively weak force. FIG. 7 shows a state when the first pressing portion 32 is pressed with a relatively strong force.

  As shown in FIG. 6, when the first pressing portion 32 is pressed with a relatively weak force, the second pressing portion 34 is not deformed, and only the first pressing portion 32 is in the main chamber 21 a of the lid body 20. It deforms toward the inside of the liquid container 1. That is, as described above, the first pressing portion is thin and easy to deform, while the second pressing portion 34 is thick and relatively difficult to deform. Therefore, when the force applied to the pressing part 30 is as small as less than a predetermined value, the second pressing part 34 is not deformed, and only the first pressing part 32 is deformed. Specifically, as shown in FIG. 6, the first pressing portion 32 enters the inside of the main chamber 21 a of the lid body 20 with the second pressing portion 34 as a fulcrum, and bulges toward the inside. It deforms as follows.

  As described above, when the first pressing portion 32 is deformed so as to enter the inside of the liquid container 1, the volume of the inner space of the liquid container 1 decreases. Accordingly, an amount of liquid corresponding to the volume reduction amount is poured out. That is, in this case, since the volume of the liquid container 1 is reduced by an amount corresponding to the deformation amount of the first pressing portion 32, only the amount of liquid corresponding to the deformation amount of the first pressing portion 32 is poured out to the outside. It is.

  On the other hand, when the first pressing portion 32 is further pressed and a relatively strong force of a predetermined value or more is applied to the pressing portion 30, the second pressing portion 34 also moves together with the first pressing portion 32 as shown in FIG. 7. Deform. Specifically, the entire pressing portions 32, 34, that is, the entire pressing portion 30, enter the inside of the main chamber 21a and deform so as to bulge out toward the inside. At this time, the second pressing portion 34 is deformed so as to be bent at a boundary portion between the first thick portion 34a and the second thick portion 34b, and the first thick portion 34a is below the second thick portion 34b. It is deformed so as to retract.

  Accordingly, the volume of the inner space of the liquid container 1 is reduced by the deformation amount of the second pressing portion 34 in addition to the deformation amount of the first pressing portion 32. Therefore, in this case, a larger amount of liquid is poured out than when only the first pressing portion 32 is deformed.

  As described above, in the present embodiment, the liquid can be poured out little by little by a simple operation of pressing the first pressing portion 32 and the pressing force applied to the first pressing portion 32 can be changed. In the procedure, the amount of liquid dispensed can be changed, and the amount of liquid dispensed can be easily changed in accordance with the application.

(3) Operation, etc. As described above, in the liquid container 1 according to the present embodiment, the first pressing portion 32 is pressed and deformed, so that the amount of liquid corresponding to the deformation amount of the pressing portion 30 is increased. Can be poured out. Therefore, it is possible to appropriately pour out liquid by a certain amount and by a small amount with a simple operation.

  Moreover, in the liquid container 1, the thin first pressing portion 32 is provided at the center of the pressing portion 30, and the relatively thick second pressing portion 34 is provided around the first pressing portion 32. Thus, as described above, a simple operation of changing the pressing force applied to the first pressing portion 32 deforms only the first pressing portion 32 and dispenses a smaller amount of liquid, and the first pressing portion. In addition to 32, it can switch to the case where the 2nd press part 34 is deformed and a comparatively large amount of liquid is poured out. Therefore, convenience can be further enhanced.

  In particular, in the liquid container 1, the first thick portion 34 a having a large thickness is provided on the inner peripheral side of the second pressing portion 34, and the second thick portion 34 b having a small thickness is provided on the outer peripheral side. Therefore, the first thick portion 34a can suppress the deformation of the second pressing portion 34 to realize the deformation of only the first pressing portion 32, and the first thick portion 34a can be replaced with the second thick portion 34b. The second thick portion 34b and thus the second pressing portion 34 can be relatively easily deformed by bending at the boundary portion. Accordingly, even when both the first pressing portion 32 and the second pressing portion 34 are deformed, the operability can be more reliably improved without requiring excessive force.

  Moreover, in the said embodiment, the width | variety of the 1st thick part 34a is set smaller than the width | variety of the 2nd thick part 34b.

  Therefore, the rigidity of the 1st thick part 34a can be improved, and it can suppress that the 2nd press part 34 deform | transforms too easily. Further, for example, the second pressing portion 34 can be bent as described above as compared with the case where the thickness of the second pressing portion 34 is set so as to be gradually reduced toward the outer side in the radial direction. The deformation of the portion 34 can be promoted.

  Moreover, in the said embodiment, the 1st press part 32 located in the center of the press part 30 has a shape which bulges upwards.

  Therefore, the user can easily recognize the central portion of the pressing portion 30 that performs the pressing operation, and the convenience can be improved. Specifically, the user can easily recognize the central portion of the pressing portion 30 to be pressed visually and tactilely because the first pressing portion 32 bulges upward. it can. Moreover, this can be easily deformed by crushing the first pressing portion 32.

  Moreover, in the said embodiment, the 2nd press part 34 also has a shape which bulges upwards, Furthermore, the shape which the 1st press part 32 bulges further further upwards rather than the 2nd press part 34. have. Therefore, the center part of the pressing part 30 to be subjected to the pressing operation can be easily recognized by the user, and the whole of the first pressing part 32 and the second pressing part 34 is crushed, thereby making the whole of these parts more It can be easily deformed.

  In the above embodiment, the first pressing portion 32 has a circular shape.

  Therefore, the pressing force applied to the first pressing portion 32 can be uniformly applied to the entire first pressing portion 32 and the pressing portion 30, and these can be appropriately deformed. Therefore, it is possible to suppress a change in the amount of liquid dispensed when the position where the pressing operation is performed in the first pressing portion 32 is different. Specifically, when the first pressing portion 32 is formed of a quadrangle or the like and a pressing force is applied near the corner portion, the force applied to the opposite corner portion is reduced, and the first pressing portion 32 is reduced. Or the press part 30 is hard to deform | transform uniformly. For this reason, the amount of deformation of the pressing portion 30 is greatly deviated between the case where the central portion of the pressing portion 30 is pressed and the amount of liquid dispensed varies. On the other hand, in the present embodiment, since the first pressing portion 32 has a circular shape, it is possible to make the distribution of the pressing force more uniform and deform them more uniformly.

  Further, in the present embodiment, the liquid container 10 is configured by the container body 10 and the lid 20 that is detachably attached to the container body 10, and the top plate portion 21 of the lid 20, that is, the pressing portion on the upper surface of the lid 20 30 is provided. Therefore, it is possible to easily inject the liquid into the container body 10 by removing the lid 20, and to easily operate the pressing unit 30 when the liquid container 1 is gripped and the liquid is poured out while being tilted. And operability can be improved.

(4) Modification Here, in the above-described embodiment, the case where the pressing unit 30 and the first pressing unit 32 bulge out of the liquid container 1 has been described, but the pressing unit 30 and the first pressing unit 32 are It does not have to bulge. However, if these are bulged as described above, convenience can be improved and these can be easily deformed.

  Moreover, although the said embodiment demonstrated the case where the perimeter of the 1st press part 32 was enclosed by the 2nd press part 34 with large thickness, a part of periphery of the 1st press part 32 of the 1st press part 32 was demonstrated. The thickness may be approximately the same as the thickness. However, if the entire circumference of the first pressing portion 32 is surrounded by the second pressing portion 34 having a large thickness, the deformation of the second pressing portion 34 can be suppressed and only the first pressing portion 32 can be more reliably deformed.

  Moreover, although the said embodiment demonstrated the case where the 2nd press part 34 was comprised by the 1st thick part 34a and the 2nd thick part 34b from which thickness differs mutually, the 2nd press part 34 is an outer periphery. It is good also as a shape where thickness becomes small as it goes to the side. However, as described above, if the second pressing portion 34 includes the first thick portion 34a and the second thick portion 34b having different thicknesses, the deformation of the second pressing portion 34 can be promoted.

  Moreover, although the said embodiment demonstrated the case where the press part 30 was provided in the upper surface of the cover body 20, the press part 30 may be provided in the outer peripheral surface etc. of the cover body 20. FIG. The pressing unit 30 may be provided on the container body 10.

  Moreover, although the case where the whole cover body 20 was integrally formed with the same material was demonstrated in the said embodiment, the cover body 20 is formed by a plurality of materials, or the lid body 20 is assembled by assembling a plurality of members. It may be formed. For example, only the pressing portion 30 of the lid 20 is formed of another synthetic resin or the like, and the other portion is formed of silicone, or only the pressing portion 30 is formed of silicone and the other portion is combined with another synthetic resin. You may form with resin etc.

  Further, the lid body 20 and the container body 10 may be formed as one member while separately providing an introduction port through which liquid can be introduced into the liquid container 1. However, as described above, if these are separated, they can be easily introduced into the liquid container body 1 and can be easily cleaned.
