Description

[Technical field]

[0001] The present invention relates to a pouring container having a pouring tool fitted into a container body. [Background technology]

[0002] Conventionally, there is a pouring container in which a pouring tool is fitted into a container body. In this pouring container, the pouring tool with a cap attached is positioned on the outer circumferential surface of the mouth of the container body while contents such as liquid detergent or liquid fabric softener are contained in the container body, and the container body and the pouring tool are fitted together by tapping. Usually, a user pours the contents in the container body into the cap through the pouring tool, and measures the contents using a scale or the like attached to the cap.

[0003] In order to tilt the container body to pour out the contents, the pouring container needs to attach the pouring tool to a predetermined circumferential position on the mouth of the container body. Therefore, the pouring container has a positioning recess on the outer circumferential surface of the mouth of the container body and a positioning protrusion on the inner circumferential surface of the pouring tool, and the positioning protrusion is guided and inserted into the positioning recess to fit the pouring tool to the outer circumferential surface of the mouth of the container body (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2013-252885 A Summary of the Invention [Problem to be solved by the invention]

[0005] A plurality of recess-forming ribs are provided at intervals on the outer peripheral surface of the mouth of the container body, forming positioning recesses between the recess-forming ribs. The recess-forming ribs have protrusions that protrude relatively far outward in the radial direction to prevent the spouting tool from rattling when fitted into the container body.

[0006] However, when the contents are placed in the container body and the capped spout is attached to the container body by plugging, there is a possibility that the container body and the spout may be fitted together with the positioning protrusion on the protruding part due to an inappropriate relative position between the container body and the spout (hereinafter, such fitting is also called "mountain fitting"). In this case, the force of the spout to remove from the mouth of the container body is greatly reduced, and the spout can easily come out of the container body.

[0007] However, when plugging, if the relative positions of the container body and the spout are not correct, it is difficult to correct the relative positions.

[0008] The present invention aims to deal with such a situation. That is, the present invention aims to provide a pouring container in which the container body and the pouring tool are stably fitted together without a significant decrease in the uncorking force, even if the container body and the pouring tool are fitted together (mountain-to-mountain fit) in a state in which the positioning protrusion formed on the inner surface of the pouring tool rides on the protrusion formed on the outer circumferential surface of the mouth of the container body. [Means for solving the problem]

[0009] In order to solve such problems, the pouring container according to the present invention has the following configuration. A pouring container comprising at least a container body in which contents are contained, and a pouring tool which is positioned on the outer peripheral surface of the mouth of the container body and fitted by stoppering, wherein a plurality of positioning recesses are formed by providing a plurality of recess-forming ribs at intervals on the outer peripheral surface of the mouth of the container body, the positioning recesses having a guide slope which gradually widens toward the upper end of the mouth and a position fixing side surface which is located below the guide slope, and a positioning protrusion which is inserted into the positioning recess when the stopper is struck is formed on the inner peripheral surface of the pouring tool, and the recess-forming ribs are A pouring container having an upper rib portion that gradually narrows toward the upper end of the mouth and forms the guide slope, and a lower rib portion located below the upper rib portion and forming the position fixing side surface, wherein the lower rib portion has a first protrusion that protrudes radially outwardly by the same or approximately the same amount as that of the upper rib portion, and a second protrusion that is located below the first protrusion and protrudes radially outwardly by a greater amount than the first protrusion, and wherein when the container body and the pouring tool are engaged, the height position of the lower end of the positioning protrusion is higher than the height position of the upper end of the second protrusion. Effect of the Invention

[0010] According to the present invention having such characteristics, even if the container body and the spouting tool are engaged in a state in which the positioning protrusion formed on the inner surface of the spouting tool rides on the protrusion formed on the outer peripheral surface of the mouth of the container body, a spouting container can be provided in which the removal force is not significantly reduced and a stable engagement state between the container body and the spouting tool is maintained.

[Figure 10] 3 is a perspective view of a mouth portion of a container body provided with a recess-forming rib of a different example from that in FIG. 2. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention (the present embodiment) will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same function, and duplicated descriptions in each drawing will be omitted as appropriate.

[0013] As shown in FIG. 1, the pouring container 1 of this embodiment includes a container body 2 in which the contents are stored, and a pouring tool 3 for pouring out the contents. The pouring container 1 also includes a cap 4 for measuring the poured contents. In this pouring container 1, the pouring tool 3 with the cap 4 attached is positioned on the outer peripheral surface 22 of the mouth portion 21 of the container body 2 in a state in which the contents are stored in the container body 2, and is fitted by plugging. When plugging, the pouring tool 3 is plugged while being pushed outward against the mouth portion 21 of the container body 2, so that the container body 2 and the pouring tool 3 are fixed in a fitted state in which the undercut 33a of the pouring tool 3 is located below the undercut 21a of the mouth portion 21.

[0014] The contents contained in the container body 2 are not particularly limited, but may be, for example, liquid contents, such as liquid detergent, liquid fabric softener, liquid bleach, and the like.

[0015] The pouring tool 3 has a pouring tube 31 for pouring out the contents, and a detachable portion 32 is formed by this pouring tube 31. As a result, when a user tilts the container body 2 to pour out the contents in the container body 2, the contents in the container body 2 can be easily poured into the cap 4 through the pouring tube 31. In addition, when a user returns the contents remaining in the cap 4 after measuring into the container body 2, the contents can be returned into the container body 2 through the detachable portion 32.

[0016] In the pouring container 1, as a configuration for mounting the pouring tool 3 having such a pouring tube 31 at a predetermined circumferential position on the mouth 21 of the container body 2, a plurality of positioning recesses 23 are formed on the outer peripheral surface 22 of the mouth 21 of the container body 2 as shown in Figs. 2 to 5, and a plurality of positioning protrusions 34 are formed on the inner peripheral surface 33 of the pouring tool 3 as shown in Figs. 6 and 7. When the pouring tool 3 is plugged into the mouth 21 of the container body 2 with the contents contained in the container body 2, the positioning protrusions 34 are inserted into the positioning recesses 23, and the undercut 33a of the pouring tool 3 is positioned below the undercut 21a of the mouth 21, so that the pouring tool 3 is fitted into the mouth 21 of the container body 2. As a result, the pouring container 1 is mounted with the pouring tool 3 at a predetermined circumferential position on the mouth 21 of the container body 2.

[0017] As shown in Figs. 2 and 3, the positioning recess 23 has a guide inclined surface 23a and a position fixing side surface 23b located below the guide inclined surface 23a. The guide inclined surface 23a has a shape that gradually widens toward the upper end side of the mouth portion 21. The guide inclined surface 23a having such a shape guides the positioning protrusion 34 toward the position fixing side surface 23b, so that the positioning protrusion 34 can be smoothly inserted into the positioning recess 23. The position fixing side surface 23b is a side surface that extends approximately parallel to the central axis O of the pouring container 1 (or the container body 2). The pouring container 1 is configured to fix the positioning protrusion 34 in the positioning recess 23, particularly between the position fixing side surfaces 23b.

[0018] In order to form a plurality of such positioning recesses 23 on the outer peripheral surface 22 of the mouth portion 21, a plurality of recess-forming ribs 24 are provided at intervals (at a constant pitch) on the outer peripheral surface 22. The interval between the recess-forming ribs 24 corresponds to the width of the positioning recesses 23, and therefore may be slightly larger than the width (circumferential length) of the positioning protrusions 34 so that the positioning protrusions 34 fitted into the positioning recesses 23 do not move in the circumferential direction.

[0019] The recess forming rib 24 has an upper rib portion 24a for forming a guide slope 23a in the positioning recess 23, and a lower rib portion 24b located below the upper rib portion 24a and for forming a position fixing side surface 23b in the positioning recess 23, as shown in Figure 3, for example.

[0020] The upper rib portion 24a has a mountain shape that protrudes radially outward and gradually narrows toward the upper end side of the mouth portion 21. Such upper rib portion 24a forms a guide slope 23a that gradually widens toward the upper end side of the mouth portion 21.

[0021] The lower rib portion 24b has a shape that protrudes radially outward and extends approximately parallel to the central axis O of the pouring container 1. The position fixing side surface 23b is formed by the lower rib portion 24b. The lower rib portion 24b has a first protrusion 24c and a second protrusion 24d located below the first protrusion 24c. The first protrusion 24c protrudes radially outward by the same or approximately the same amount as the upper rib portion 24a. The height of the lower rib portion 24b may be, for example, about 1 / 2 the height of the recess forming rib 24, but is not limited thereto.

[0022] The second protrusion 24d is greater in radial outward projection than the first protrusion 24c and is the most radially outward projection in the recess forming rib 24. Such first protrusion 24c and second protrusion 24d are provided via a step. The height of the second protrusion 24d may be, for example, 1 / 4 to 1 / 2 the height of the lower rib 24b, but is not limited thereto. In addition, in the fitted state between the container body 2 and the spouting tool 3, the radial outward projection of the second protrusion 24d may be such that it does not protrude beyond the undercut 21a provided in the mouth 21 of the container body 2, and the outer diameter of the second protrusion 24d is the same or approximately the same dimension as the inner diameter of the inner circumferential surface 33 of the spouting tool 3, so that the second protrusion 24d is in close contact with the inner circumferential surface 33 of the spouting tool 3 after stoppering. The second protruding portion 24d having such a protruding amount prevents rattling between the mouth portion 21 of the container body 2 and the dispensing tool 3 in a state in which the container body 2 and the dispensing tool 3 are fitted together after stoppering.

[0023] In the pouring container 1 of this embodiment, two sets of five recess-forming ribs 24 spaced apart (at a fixed pitch) are provided on the outer peripheral surface 22 of the mouth 21 of the container body 2, as shown in Figures 2 and 5 (i.e., a total of ten recess-forming ribs 24 are provided on the outer peripheral surface 22). As shown in Figure 5, on the outer peripheral surface 22, the two sets of five recess-forming ribs 24 are provided such that the recess-forming ribs 24 are axially symmetrical to each other about the central axis O.

[0024] In addition, a plurality of fixing ribs 25 are provided on the outer peripheral surface 22 of the mouth portion 21 as a configuration for fixing the spout 3 together with the recess-forming ribs 24. In this embodiment, two fixing ribs 25 are provided in positions on the outer peripheral surface 22 where the recess-forming ribs 24 are not provided, so as to be symmetrical with respect to the central axis O. As a result, in this embodiment, a total of eight positioning recesses 23 into which positioning protrusions 34 are inserted are formed on the outer peripheral surface 22 of the mouth portion 21 between adjacent recess-forming ribs 24 and between the recess-forming ribs 24 and the fixing ribs 25.

[0025] The height of the fixing rib 25 is not particularly limited, but may be the same or approximately the same as the height of the lower rib portion 24b of the recess-forming rib 24, as shown in FIG. 3, for example. The width (circumferential length) of the fixing rib 25 may be longer than the width (circumferential length) of the recess-forming rib 24, as shown in FIG. 4 and FIG. 5, for example. The radial outward projection amount of the fixing rib 25 may be the same or approximately the same as the projection amount of the second projection portion 24d. As a result, when the container is capped, the fixing rib 25 and the recess-forming rib 24 come into close contact with the inner peripheral surface 33 of the dispensing tool 3, so that rattling between the mouth portion 21 of the container body 2 and the dispensing tool 3 after capping is further prevented.

[0026] The number and arrangement of recess-forming ribs 24 and the number and arrangement of fixing ribs 25 on outer peripheral surface 22 of mouth portion 21 are not limited to the above. The number of recess-forming ribs 24 formed on outer peripheral surface 22 may be any number as long as there is more than one, and the arrangement may also be other. The number of fixing ribs 25 formed on outer peripheral surface 22 may be any number, and the arrangement may also be other.

[0027] The positioning protrusions 34, which are inserted into the positioning recesses 23 through the guide slopes 23a when stoppering, are provided on the inner peripheral surface 33 of the spout 3, as shown in Figs. 6 and 7, for example, and have an elongated shape extending along the central axis O of the spouting container 1 (spout 3). In this embodiment, two sets of four positioning protrusions 34 are provided at regular intervals on the inner peripheral surface 33 of the spout 3 (i.e., a total of eight positioning protrusions 34 are provided on the inner peripheral surface 33). On this inner peripheral surface 33, the two sets of four positioning protrusions 34 are provided so that the positioning protrusions 34 are axially symmetrical to each other about the central axis O.

[0028] In such a pouring container 1, the pouring tool 3 is fitted to the outer peripheral surface 22 of the mouth part 21 of the container body 2 by fitting the positioning protrusions 34 formed on the inner peripheral surface 33 of the pouring tool 3 into the positioning recesses 23 formed on the outer peripheral surface 22 of the mouth part 21. For example, four adjacent positioning protrusions 34 formed on the inner peripheral surface 33 of the pouring tool 3 are fitted into four positioning recesses 23 between adjacent recess forming ribs 24 in the assembly of five recess forming ribs 24 formed on the outer peripheral surface 22 of the mouth part 21.

[0029] When the container body 2 and the dispensing tool 3 are engaged in this manner, as shown in Figure 8, for example, the height position H2 of the lower end of the positioning protrusion 34 formed on the inner surface 33 of the dispensing tool 3 is above the height position H1 of the upper end of the second protrusion 24d, which has the greatest radial outward protrusion in the recess forming rib 24 formed on the outer surface 22 of the container body 2.

[0030] In the case where the container body 2 and the dispensing tool 3 are fitted together (mountain-to-mountain fit) with the positioning protrusion 34 riding on the recess-forming rib 24 (i.e., the positioning protrusion 34 is in contact with the radially outer side of the recess-forming rib 24) as shown in Fig. 9, the height position H2 of the lower end of the positioning protrusion 34 is located above the height position H1 of the upper end of the second protrusion 24d. In other words, in the dispensing container 1 in such a mountain-to-mountain fit state, even if the positioning protrusion 34 rides on the upper rib portion 24a and the first protrusion 24c of the recess-forming rib 24, it does not ride on the second protrusion 24d which has the largest radially outward protrusion.

[0031] Therefore, in the pouring container 1 in this mountain-fitting state, the clearance between the undercut 21a of the container body 2 and the inner peripheral surface 33 of the pouring tool 3 does not increase significantly. As a result, even in the pouring container 1 in this state, a significant decrease in the uncorking force is suppressed, and the pouring tool 3 and the cap 4 attached thereto are prevented from coming off the container body 2.

[0032] Furthermore, the recess-forming rib 24 of the container body 2 has, at the lower rib portion 24b, the second protrusion 24d which protrudes radially outward the greatest amount below the first protrusion 24c, so that even with the pouring container 1 in this mountain-to-mount fit state, rattling between the container body 2 and the pouring tool 3 is prevented and a stable fit state can be maintained.

[0033] Although the present embodiment has been described in detail with reference to the drawings, the specific configuration is not limited to the present embodiment, and the present invention includes design changes and the like that do not deviate from the gist of the present invention. In addition, the above-mentioned examples can be combined by utilizing each other's technologies as long as there are no particular contradictions or problems in the purpose, configuration, etc.

[0034] The container body 2 of the pouring container 1 may be provided with a recess-forming rib 24A as shown in Fig. 10 on the outer peripheral surface 22 of the spout 21 instead of the recess-forming rib 24 described above. In this recess-forming rib 24A, a lower rib portion 24B located below the upper rib portion 24a has a first protrusion 24c and a second protrusion 24d, as well as a third protrusion 24e above the second protrusion 24d, the amount of radial outward protrusion of which is the same or approximately the same as that of the second protrusion 24d.

[0035] In the example of Fig. 10, two third protrusions 24e are formed, one at each of the right and left ends of the upper side of the second protrusion 24d. The number of third protrusions 24e formed on the upper side of the second protrusion 24d is not limited to this, and may be one or more than two. The shape of the third protrusion 24e is not limited to the rectangle shown in the example of Fig. 10, and may be, for example, a square, a triangle, or a trapezoid.

[0036] By providing a recess-forming rib 24A having such a lower rib portion 24B on the outer peripheral surface of the mouth 21 of the container body 2, the pouring container 1 further prevents rattling between the mouth 21 of the container body 2 and the pouring tool 3 when the container body 2 and the pouring tool 3 are engaged after stoppering.

[0037] In the pouring container 1 having such a container body 2, even if the above-mentioned mountain-to-mount fit state occurs during plugging, when the positioning protrusion 34 rides on the first protrusion 24c so as to be sandwiched between the two third protrusions 24e of the recess forming rib 24A, the clearance does not increase significantly as described above, and a significant decrease in the plugging force is suppressed. As a result, the pouring tool 3 and the cap 4 attached thereto are prevented from coming off the container body 2.

[0038] 1 to 9, the recess-forming rib 24 provided on the mouth 21 of the container body 2 has the first protrusion 24c and the second protrusion 24d on the lower rib portion 24b provided with a step, but is not limited thereto. For example, the first protrusion 24c and the second protrusion 24d may be provided with a curved surface or an inclined surface instead of a step. [Explanation of symbols]
