Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above conventional discharge container, in order to prevent the content from leaking when the container body is in an inverted posture, it is conceivable to provide a slit valve in the discharge cap.

[0005] However, since the pressure inside the container body when discharging the content decreases as the remaining amount of the content stored inside the container body decreases, there is a problem that when the remaining amount of the content decreases, it becomes difficult to apply pressure to the slit valve and the discharge amount of the content decreases.

[0006] An object of the present invention is to solve such problems, and an object thereof is to provide a discharge container capable of discharging the content quantitatively regardless of the remaining amount of the content.

Mode for Carrying Out the Invention

[0013] Hereinafter, the discharge container 1 according to an embodiment of the present invention will be more specifically illustrated and described with reference to the drawings.

[0014] In the present specification and claims, the vertical direction means the upper and lower directions in a state where the discharge container 1 is in an upright posture as shown in FIG. 1. Further, the radial direction means a direction along a straight line passing through the axis O of the discharge container 1 and perpendicular to the axis O. Furthermore, the circumferential direction means the circumferential direction centered on the axis O.

[0015] The discharge container 1 according to an embodiment of the present invention is used, for example, for storing a liquid seasoning such as soy sauce as the content.

[0016] The discharge container 1 has a container body 10 and a discharge cap 20.

[0017] The container body 10 is, for example, a blow-molded bottle made of a synthetic resin such as PET (polyethylene terephthalate resin), PP (polypropylene resin), or PE (polyethylene resin). The container body 10 includes a cylindrical mouth portion 11, a body portion 12 connected to the lower end of the mouth portion 11, and a bottom portion 13 closing the lower end of the body portion 12, and can store the content therein.

[0018] In the present embodiment, the mouth portion 11 has a cylindrical shape centered on the axis O, and a male screw 11a is integrally provided on the outer peripheral surface thereof.

[0019] Note that the mouth part 11 may be configured such that an annular protrusion is provided on its outer peripheral surface instead of the male thread 11a. In this case, the mouth part 11 may be a tubular shape other than a cylindrical shape such as a square tubular shape or an elliptical tubular shape.

[0020] In this embodiment, the body part 12 includes a shoulder-shaped part 12a integrally connected to the lower end of the mouth part 11, a cylindrical squeeze part 12b integrally connected to the lower end of the shoulder-shaped part 12a, and a drum-shaped lower body part 12c integrally connected to the lower end of the squeeze part 12b. An annular concave rib 12d extending in the circumferential direction centered on the axis O is provided between the squeeze part 12b and the lower body part 12c.

[0021] The squeeze part 12b is elastically deformable inward in the radial direction by being pressed inward in the radial direction, that is, along the radial direction toward the inside of the container.

[0022] The bottom part 13 is integrally connected to the lower end of the body part 12 (the lower end of the lower body part 12c) and closes the lower end of the body part 12.

[0023] As shown in FIGS. 1 and 2, a plurality of vertical ribs 14 are provided on the squeeze part 12b at intervals in the circumferential direction. The plurality of vertical ribs 14 are parallel to each other and each extends parallel to the axis O. In this embodiment, the plurality of vertical ribs 14 are each a concave rib that is concave inward in the radial direction.

[0024] Also, a plurality of columnar parts 15 are provided on the squeeze part 12b in sections formed between a pair of adjacent vertical ribs 14. Each of the plurality of columnar parts 15 has an arc-shaped cross section perpendicular to the axis O.

[0025] In this way, on the squeeze part 12b, the plurality of vertical ribs 14 and the plurality of columnar parts 15 are alternately provided in the circumferential direction.

[0026] In this embodiment, the number of the vertical ribs 14 and the columnar parts 15 provided on the squeeze part 12b is 14 each, but these numbers can be changed as appropriate.

[0027] Here, the plurality of columnar portions 15 provided in the squeeze portion 12b have a plurality of types with different circumferential widths from each other. In the present embodiment, the squeeze portion 12b is provided with 11 first columnar portions 15a, a second columnar portion 15b having a circumferential width wider than that of the first columnar portion 15a, a third columnar portion 15c having a circumferential width wider than that of the second columnar portion 15b, and a fourth columnar portion 15d having a circumferential width wider than that of the third columnar portion 15c, and four types of columnar portions 15 with different circumferential widths from each other are provided.

[0028] The circumferential width of each of the first columnar portions 15a is approximately the same as the circumferential width of the vertical ribs 14. The portion where the plurality of vertical ribs 14 and the 11 first columnar portions 15a of the squeeze portion 12b are provided cannot be easily elastically deformed radially inward even when pressed (squeezed) radially inward by the user.

[0029] On the other hand, the squeeze portion 12b can be elastically deformed more easily radially inward in the portion where the second columnar portion 15b having a circumferential width wider than that of the first columnar portion 15a is provided than in the portion where the plurality of vertical ribs 14 and the 11 first columnar portions 15a are provided. That is, when the second columnar portion 15b is pressed (squeezed) radially inward by the user, it can elastically deform radially inward by a predetermined amount of deformation between the pair of vertical ribs 14.

[0030] Further, the squeeze portion 12b can be elastically deformed more easily radially inward in the portion where the third columnar portion 15c having a circumferential width wider than that of the second columnar portion 15b is provided than in the portion where the second columnar portion 15b is provided. That is, when the third columnar portion 15c is pressed (squeezed) radially inward by the user, it can elastically deform radially inward between the pair of vertical ribs 14 by a larger amount of deformation than the second columnar portion 15b.

[0031] Furthermore, in the portion where the squeezing portion 12b is provided with the fourth columnar portion 15d having a circumferential width wider than that of the third columnar portion 15c, it can be elastically deformed more easily radially inward than in the portion where the third columnar portion 15c is provided. That is, when the fourth columnar portion 15d is pressed (squeezed) radially inward by the user, it can elastically deform radially inward between the pair of vertical ribs 14 with a larger deformation amount than the third columnar portion 15c.

[0032] Thus, the plurality of types of columnar portions 15 having different circumferential widths are configured such that the amount of elastic deformation radially inward increases as the circumferential width increases. That is, the discharge container 1 can adjust the discharge amount of the content by selectively pressing (squeezing) any one of the plurality of types of columnar portions 15 having different circumferential widths. In the present embodiment, by pressing the second columnar portion 15b, a predetermined amount of the content can be discharged from the discharge cap 20, and by pressing the third columnar portion 15c, a larger predetermined amount of the content can be discharged from the discharge cap 20 than when the second columnar portion 15b is pressed, and by pressing the fourth columnar portion 15d, a larger predetermined amount of the content can be discharged from the discharge cap 20 than when the third columnar portion 15c is pressed.

[0033] On the outer surfaces of the second columnar portion 15b, the third columnar portion 15c, and the fourth columnar portion 15d, a display 16 indicating the amount of elastic deformation, that is, the magnitude of the discharge amount of the content, may be displayed by unevenness or the like. For example, the display 16 can be displayed by bars having different numbers and lengths according to the magnitude of the discharge amount of the content.

[0034] As shown in FIG. 1, the discharge cap 20 includes a discharge cylinder 21 for discharging the content and is attached to the mouth portion 11 of the container body 10. The discharge cap 20 also has a slit valve 22 attached to the discharge cylinder 21 to open and close the flow path 21a inside the discharge cylinder 21, and a baffle plate 23 disposed below the lower end opening 21b of the discharge cylinder 21 at an interval from the lower end opening 21b.

[0035] More specifically, the discharge cap 20 includes a capped cylindrical cap body 24, and the cap body 24 is screwed onto the male thread 11a to be attached to the mouth portion 11.

[0036] The discharge tube 21 has a main body tube portion 21c integrally provided on the top wall 24a of the cap body 24, and the main body tube portion 21c protrudes upward from the top wall 24a. Further, a flange body 25 is fitted and fixed inside the discharge tube 21, and an inner cylindrical portion 21d that forms a part of the discharge tube 21 is integrally provided on the flange body 25. The inner cylindrical portion 21d is cylindrical and forms a part of the flow path 21a and the lower end opening 21b of the discharge tube 21.

[0037] As shown in FIGS. 1 and 3, the slit valve 22 is formed of an elastic body such as synthetic rubber, and has a valve main body portion 22a and a support portion 22b that supports the valve main body portion 22a. The valve main body portion 22a is in the shape of a thin disk, and is disposed inside the main body tube portion 21c above the inner cylindrical portion 21d to block the flow path 21a. A slit-like slit 22c that penetrates the valve main body portion 22a vertically is provided in the valve main body portion 22a. In the natural state, the slit valve 22 closes the flow path 21a with the valve main body portion 22a, and when the pressure inside the container body 10 increases, the slit 22c elastically deforms to open the flow path 21a.

[0038] In the present embodiment, the slit valve 22 is configured to have a cross-shaped slit 22c with the intersection coinciding with the center of the valve main body portion 22a. However, as long as it has a slit, for example, it may have a single linear slit passing through the center of the valve main body portion 22a.

[0039] The support portion 22b is annular and is integrally connected to the valve main body portion 22a by a cylindrical connecting wall 22d. The slit valve 22 is fixed to the discharge tube 21 by the support portion 22b being sandwiched between the main body tube portion 21c and the inner cylindrical portion 21d.

[0040] As shown in FIGS. 1 and 4, the baffle plate 23 is in the shape of a disc having the same diameter as the circular lower end opening 21b of the discharge cylinder 21. On the lower surface of the top wall 24a, a plurality (six) of legs 27 are integrally provided, which extend parallel to the axis O and are arranged at equal intervals in the circumferential direction. The baffle plate 23 is integrally connected to the lower ends of these legs 27, and is disposed below the lower end opening 21b at a distance from the lower end opening 21b. The lower end opening 21b communicates with the inside of the container body 10 through the space between a pair of adjacent legs 27.

[0041] The discharge cap 20 can also be configured to include an overcap 30 that covers the discharge cylinder 21. In the present embodiment, the overcap 30 is configured to be detachably attached to the cap body 24 by screw connection.

[0042] Next, the procedure for discharging the contents from the discharge container 1 according to the present embodiment will be described.

[0043] First, as shown in FIG. 5, with the overcap 30 removed from the cap body 24, the discharge container 1 is placed in an inverted posture so that the container body 10 is positioned above the discharge cap 20. Then, in this state, the squeeze portion 12b provided on the body portion 12 of the container body 10 is pressed (squeezed) inward in the radial direction.

[0044] When the squeeze portion 12b is pressed (squeezed) inward in the radial direction, the pressure inside the container body 10 increases, whereby the slit valve 22 opens and the contents stored inside the container body 10 are discharged to the outside from the tip of the discharge cylinder 21 through the flow path 21a.

[0045] At this time, in the discharge container 1 according to the present embodiment, as shown in FIG. 6, by selectively pressing (squeezing) any one of the plurality of types of columnar portions 15 provided on the squeeze portion 12b and having different circumferential widths, the contents can be easily discharged quantitatively with a desired discharge amount.

[0046] For example, by pressing (squeezing) the second columnar portion 15b provided in the squeeze portion 12b, a desired amount (for example, an amount less than one tablespoon) of the content can be easily discharged quantitatively in a droplet form. Also, by pressing (squeezing) the third columnar portion 15c provided in the squeeze portion 12b, an amount of the content larger than that when the second columnar portion 15b is pressed (for example, one tablespoon) can be easily discharged quantitatively. Further, by pressing (squeezing) the fourth columnar portion 15d provided in the squeeze portion 12b, an amount of the content larger than that when the third columnar portion 15c is pressed (for example, one large tablespoon) can be easily discharged quantitatively. The selection of the discharge amount of the content can be easily performed by checking the indication 16 described on each columnar portion 15.

[0047] Also, in the discharge container 1 according to the present embodiment, since the baffle plate 23 is disposed below the lower end opening 21b of the discharge cylinder 21 with a space from the lower end opening 21b, when the squeeze portion 12b is pressed (squeezed) inward in the radial direction and the content is discharged, the content inside the container body 10 flows into the flow path 21a of the discharge cylinder 21 from the lower end opening 21b so as to go around the baffle plate 23. Therefore, the content flows into the flow path 21a of the discharge cylinder 21 from the lower end opening 21b at a higher pressure than when the baffle plate 23 is not provided. Accordingly, according to the discharge container 1 according to the present embodiment, even when the remaining amount of the content stored inside the container body 10 decreases and the pressure applied to the content when the squeeze portion 12b is squeezed decreases, the content flows into the flow path 21a from the lower end opening 21b at an appropriate pressure so that the slit valve 22 surely opens at that pressure, and it is possible to suppress the slit valve 22 from unexpectedly closing and the discharge amount from decreasing. In particular, when the baffle plate 23 is supported by a plurality of leg portions 27, the resistance of the content flowing from the lower end opening 21b into the flow path 21a of the discharge cylinder 21 is increased by the basket-shaped portion formed by the baffle plate 23 and the plurality of leg portions 27, so that the slit valve 22 can be more surely opened.

[0048] As described above, according to the discharge container 1 according to this embodiment, regardless of the remaining amount of the content, the content can be easily discharged quantitatively one by one in a desired discharge amount. In particular, when the content stored in the container body 10 is a seasoning that requires measurement during use, such as soy sauce, the content can be easily quantified and discharged in a desired discharge amount without using another measuring instrument such as a measuring spoon. Therefore, it is suitable for the use purpose of the discharge container 1.

[0049] Furthermore, in the discharge container 1 according to this embodiment, when the remaining amount of the content stored inside the container body 10 is large, the content can be prevented from flowing into the flow path 21a of the discharge cylinder 21 from the lower end opening 21b by flowing around the baffle plate 23. Thereby, it is possible to prevent the content from flowing into the flow path 21a at an excessively high pressure. As a result, it is possible to prevent the slit valve 22 from opening vigorously due to the excessively high pressure of the content and the content from splashing out of the discharge cylinder 21.

[0050] The discharge container 1 shown in FIGS. 1 to 6 is of a single-side deformation type in which, when discharging the content, any one of the second columnar portion 15b, the third columnar portion 15c, and the fourth columnar portion 15d is selectively pressed on one side with respect to the axis O of the squeeze portion 12b.

[0051] On the other hand, as schematically shown in FIG. 7 as a modification, a plurality of columnar portions 15 provided on the squeeze portion 12b are arranged symmetrically with respect to each other across the axis O, and a pair of second columnar portions 15b arranged symmetrically with respect to each other across the axis O, and a pair of third columnar portions 15c arranged symmetrically with respect to each other across the axis O and adjacent to each second columnar portion 15b with a vertical rib 14 interposed therebetween, and a pair of fourth columnar portions 15d arranged symmetrically with respect to each other across the axis O and adjacent to each third columnar portion 15c with a vertical rib 14 interposed therebetween. By adopting such a configuration, when discharging the content, it is also possible to adopt a double-side deformation type in which any one pair of the pair of second columnar portions 15b, the pair of third columnar portions 15c, and the pair of fourth columnar portions 15d is selectively pressed on both sides with respect to the axis O of the squeeze portion 12b.

[0052] According to such a double-sided deformation type, since a pair of columnar portions 15 having the same circumferential width can be pressed from both sides sandwiching the axis O by the hand holding the squeezing portion 12b, the operability when discharging the content can be enhanced.

[0053] FIG. 8 is a front view showing a cross section of a part of a discharge container 100 according to another embodiment of the present invention, FIG. 9 is a cross-sectional view taken along line C-C in FIG. 8, FIG. 10 is an explanatory view showing a state where the content of the discharge container shown in FIG. 8 is being discharged, and FIG. 11 is an explanatory view schematically showing the relationship of the deformation amounts of a plurality of types of columnar portions in the discharge container shown in FIG. 8. In FIGS. 8 to 11, the above-described members are denoted by the same reference numerals, and repeated explanations are appropriately omitted.

[0054] The discharge cap 20 of the discharge container 100 shown in FIG. 8 has the same basic configuration as the discharge cap 20 of the discharge container 1 shown in FIG. 1, but is different in that the overcap 30 is connected to the cap body 24 by a hinge 31 so as to be openable and closable.

[0055] On the other hand, in the discharge container 100 shown in FIG. 8, the container body 10 has a configuration in which the body portion 12 has a first squeezing portion 12e and a second squeezing portion 12f. More specifically, the first squeezing portion 12e is cylindrical and is integrally connected to the lower end of the shoulder portion 12a. The second squeezing portion 12f is cylindrical with a larger diameter than the first squeezing portion 12e, and is integrally connected to the lower end of the first squeezing portion 12e via an overhanging portion 12g. Note that a body lower portion 12c is integrally connected to the lower end of the second squeezing portion 12f via an overhanging portion 12h.

[0056] As shown in FIGS. 8 and 9, a plurality of vertical ribs 14 are provided at intervals in the circumferential direction on the first squeezing portion 12e. Further, a plurality of columnar portions 15 partitioned between a pair of vertical ribs 14 are provided on the first squeezing portion 12e. In the present embodiment, the number of the vertical ribs 14 and the columnar portions 15 provided on the first squeezing portion 12e is 10 each, but these numbers can be appropriately changed.

[0057] More specifically, the plurality of columnar portions 15 provided in the first squeezing portion 12e include a plurality of first columnar portions 15e and a second columnar portion 15f having a wider circumferential width than the first columnar portion 15e. In the present embodiment, the first squeezing portion 12e is provided with eight first columnar portions 15e and two second columnar portions 15f that are symmetric with each other across the axis O.

[0058] Similarly, in the second squeezing portion 12f, a plurality of vertical ribs 14 are provided side by side at intervals in the circumferential direction. Further, in the second squeezing portion 12f, a plurality of columnar portions 15 partitioned between a pair of vertical ribs 14 are provided. In the present embodiment, the number of the vertical ribs 14 and the columnar portions 15 provided in the second squeezing portion 12f is six each, but these numbers can be changed as appropriate.

[0059] More specifically, the plurality of columnar portions 15 provided in the second squeezing portion 12f include a plurality of third columnar portions 15g and a fourth columnar portion 15h having a wider circumferential width than the third columnar portion 15g. In the present embodiment, the second squeezing portion 12f is provided with four third columnar portions 15g and two fourth columnar portions 15h that are symmetric with each other across the axis O.

[0060] Also in the discharge container 100, on the outer surfaces of the second columnar portion 15f and the fourth columnar portion 15h, a display 16 indicating the elastic deformation amount, that is, the magnitude of the discharge amount of the content, may be displayed by unevenness or the like. For example, the display 16 can be displayed by bars having different circumferential lengths according to the magnitude of the discharge amount of the content.

[0061] Even in the discharge container 100 having the above-described configuration, as shown in FIG. 10, with the overcap 30 open, the discharge container 1 is placed in an inverted posture such that the container body 10 is positioned above the discharge cap 20. In this state, by selectively pressing (squeezing) either the first squeezing portion 12e or the second squeezing portion 12f provided on the body portion 12 of the container body 10 radially inward, the content can be discharged from the discharge tube 21 of the discharge cap 20. At this time, as shown in FIGS. 10 and 11, by selectively pressing (squeezing) either one of the second columnar portion 15f provided on the first squeezing portion 12e and the fourth columnar portion 15h provided on the second squeezing portion 12f, the content can be easily discharged quantitatively with a desired discharge amount.

[0062] For example, by pressing (squeezing) the second columnar portion 15f provided on the first squeezing portion 12e, a desired amount of the content can be easily discharged quantitatively. On the other hand, by pressing (squeezing) the fourth columnar portion 15h provided on the second squeezing portion 12f, a larger amount of the content can be easily discharged quantitatively than when the second columnar portion 15f provided on the first squeezing portion 12e is pressed. The selection of the discharge amount of the content can be easily performed by checking the indication 16 described on each columnar portion 15.

[0063] In this way, in the discharge container 100, since the first squeezing portion 12e and the second squeezing portion 12f are arranged offset in the direction of the axis O and their outer diameters are different from each other, it is possible to easily select the discharge amount of the content.

[0064] Also, in the discharge container 100, since the same discharge cap 20 as that of the discharge container 1 shown in FIGS. 1 to 7 is attached, by pressing (squeezing) the second columnar portion 15f provided on the first squeezing portion 12e or the fourth columnar portion 15h provided on the second squeezing portion 12f, the content can be discharged quantitatively regardless of the remaining amount of the content.

[0065] In the case shown in FIGS. 8 to 11, the discharge container 100 is provided with a pair of second columnar portions 15f on both sides of the first squeezing portion 12e with the axis O therebetween, and a pair of fourth columnar portions 15h on both sides of the second squeezing portion 12f with the axis O therebetween, which is a type of both-side deformation. However, it may be a type of one-side deformation in which only one second columnar portion 15f is provided in the first squeezing portion 12e and only one fourth columnar portion 15h is provided in the second squeezing portion 12f.

[0066] Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof.

[0067] For example, the discharge containers 1 and 100 can also be used for applications that store contents other than liquid seasonings such as soy sauce.

[0068] In the above-described embodiment, the plurality of vertical ribs 14 are concave ribs that are recessed toward the radially inner side (inside the container), but they may be convex ribs that protrude toward the radially outer side (outside the container).
