Description

[Technical field]

[0001] The present invention relates to a dispensing member. [Background technology]

[0002] a mounting tube portion to be mounted on the mouth of a refillable container that contains the contents to be refilled into the main container; A pouring member including a cylindrical attachment portion and a cylindrical pouring portion extending upwardly from the cylindrical attachment portion is known. Generally, in order to efficiently perform the refilling operation of transferring the contents of a refill container into the main container, the pouring posture of the refill container is made different depending on whether or not contents remain in the refill container after the refilling operation (for example, when the content volume of the refill container is greater than the content volume of the main container) and whether or not contents remain. In the former case, the contents of the refillable container are poured into the main container with the outer surface of the pouring tube not inserted into the mouth of the main container, but with the outer surface of the pouring tube placed on the upper opening edge of the mouth of the main container; in the latter case, the body of the refillable container is squeezed and deformed, etc., with the pouring tube inserted into the mouth of the main container, to forcibly eject the contents.

[0003] [Patent Document 1] JP 2010-126220 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the former case, depending on the force of the contents poured out of the pouring tube, there is a risk that the contents may overflow from the mouth of the main container, particularly if, for example, the content volume of the refill container is greater than the content volume of the main container. In the latter case, a liquid film may form between the outer peripheral surface of the pouring tube and the inner peripheral surface of the mouth of the main container, which may turn into bubbles and overflow from the mouth of the main container.

[0005] The present invention provides a pouring member that can pour the contents into the refillable container without causing the contents to overflow from the opening, regardless of the pouring position of the refillable container. [Means for solving the problem]

[0006] The pouring member according to one embodiment of the present invention comprises an attachment tubular portion that is attached to the mouth of a refillable container that contains the contents to be refilled into the container, and an ejection tubular portion that extends upward from the attachment tubular portion. The ejection tubular portion comprises a convex peripheral wall and a concave peripheral wall that are curved or bent so as to protrude in one radial direction when viewed from above and below, and a pair of end peripheral walls that connect the circumferential ends of the convex peripheral wall and the concave peripheral wall, and is generally C-shaped when viewed from above and below, opening in the other radial direction that is opposite to the one radial direction.

[0007] Since the pouring tube portion has an approximately C-shape that opens in the other direction when viewed from the top and bottom, it is easy to ensure the flow path cross-sectional area of ​​the contents while keeping the size of the pouring tube portion in the other direction small. In this way, because the size of the pouring tube portion in other directions is kept small, it is possible to ensure a wide gap between the outer surface of the concave peripheral wall and the inner surface of the mouth of the container when the pouring tube portion is inserted into the mouth of the container and the outer surface of the convex peripheral wall is abutting or close to the inner surface of the mouth of the container.When the contents are poured out of the pouring tube portion in this state, not only is it difficult for a liquid film to form and space for air replacement within the container can be secured, but it is also possible to prevent the contents from dripping from the upper opening of the pouring tube portion. Furthermore, as mentioned above, since it becomes easier to ensure the cross-sectional flow path area of ​​the contents in the pouring tube portion, clogging of the contents is suppressed and the pressing force applied to the squeezeable body portion of the refillable container can be easily adjusted. When the outer peripheral surface of the convex peripheral wall is placed on the upper opening edge of the mouth portion of the main container and the body portion is squeezed and deformed to inject the contents in the refillable container into the main container, it is possible to prevent the contents poured out of the pouring tube portion from overflowing from the mouth portion of the main container. As a result, regardless of the pouring position of the refill container, the contents can be poured into the main container without overflowing from the opening.

[0008] A circumferential center portion of the recessed peripheral wall may be located at a radial distance from a central axis of the mounting tubular portion in one direction, or at the same radial position.

[0009] Since the circumferential center of the concave peripheral wall is located radially away from the central axis of the mounting tubular portion in one direction or at the same radial position, when the pouring tubular portion is inserted into the mouth of the container and the outer surface of the convex peripheral wall abuts or is close to the inner surface of the mouth of the container, a wide gap can be reliably secured between the outer surface of the concave peripheral wall and the inner surface of the mouth of the container.

[0010] In the convex peripheral wall, the outer peripheral surface of the upper part is located radially inward from the outer peripheral surface of the lower part, and an upwardly facing step is formed at the connecting portion between the upper part and the lower part of the outer peripheral surface of the convex peripheral wall, and the step may be engaged with a locking portion provided on the main container when the refillable container is in a pouring position with the mouth facing downward.

[0011] A step is formed on the outer peripheral surface of the convex peripheral wall, which engages with a locking portion provided on the main container when the refillable container is in the pouring position, thereby stabilizing the pouring position of the refillable container. Effect of the Invention

[0012] According to one aspect of the present invention, regardless of the pouring position of the refillable container, the contents can be poured into the main container without overflowing from the mouth. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, a pouring member according to one embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, the pouring member 1 according to this embodiment includes an attachment tube part 13 attached to a mouth part 12 of a refill container 11 that contains the contents to be refilled into the main container 20 (see Figs. 3 and 4), and a pouring tube part 14 standing up from the attachment tube part 13. The body part of the refill container 11 is formed so as to be elastically deformable in the radial direction.

[0015] Hereinafter, the tip side of the pouring / dispensing tube portion 14 along the central axis O of the mounting tube portion 13 will be referred to as the upper side, the opposite side will be referred to as the lower side, the direction along the central axis O will be referred to as the up-down direction, the direction that intersects the central axis O when viewed from the up-down direction will be referred to as the radial direction, and the direction that rotates around the central axis O will be referred to as the circumferential direction.

[0016] The mounting tube portion 13 is formed in a topped tube shape having an annular top wall. A female thread portion that screws into the mouth portion 12 is formed on the inner peripheral surface of the peripheral wall of the mounting tube portion 13. A connecting tube portion 15 that extends upward is formed on the inner peripheral edge of the top wall of the mounting tube portion 13. The pouring / discharging tube portion 14 extends upward from the connecting tube portion 15 .

[0017] The injection / discharge tube portion 14 includes a convex peripheral wall 21 and a concave peripheral wall 22 that are curved or bent so as to protrude toward one radial direction (hereinafter, referred to as one direction X) when viewed from the top-bottom direction, and a pair of end peripheral walls 23 that connect the circumferential ends of the convex peripheral wall 21 and the concave peripheral wall 22, and has a substantially C-shape that opens toward the other radial direction (hereinafter, referred to as the other direction Y) opposite to the one radial direction X when viewed from the top-bottom direction. As shown in Fig. 2, the convex peripheral wall 21 and the concave peripheral wall 22 are curved so as to protrude toward the one radial direction X when viewed from the top-bottom direction.

[0018] The outer circumferential surface of the convex peripheral wall 21 is formed as a curved surface protruding in the one direction X, and the outer circumferential surface of the concave peripheral wall 22 is formed as a curved surface recessed in the one direction X. The size of the upper end opening of the pouring / discharging tube portion 14 in the one direction X decreases with increasing distance from the circumferential center in the circumferential direction.

[0019] The convex peripheral wall 21 and the concave peripheral wall 22 are arranged side by side in one direction X. The circumferential center portions of the convex peripheral wall 21 and the concave peripheral wall 22 are spaced apart in the one direction X from the central axis O. The central axis O may be located at the circumferential center portion of the concave peripheral wall 22. The pair of end peripheral walls 23 have a curved shape that protrudes in the other direction Y when viewed from the top-bottom direction. The apex of the end peripheral walls 23 in the other direction Y is separated in the other direction Y from the central axis O. The pair of end peripheral walls 23 protrude in the other direction Y from the central axis O. Note that the pair of end peripheral walls 23 may be separated in one direction X or the other direction Y from the central axis O.

[0020] In the convex peripheral wall 21, the outer peripheral surface of the upper part is located radially inward from the outer peripheral surface of the lower part. In the outer peripheral surface of the convex peripheral wall 21, an upwardly facing step 21a is formed at the connecting portion between the upper part and the lower part. When the refillable container 11 is in the pouring position such that the mouth 12 of the refillable container 11 faces downward, the step 21a is engaged with a connecting wall 20d (engagement portion) or a protrusion 20a (engagement portion) provided on the main container 20, which will be described later.

[0021] Here, as shown in Fig. 3 and Fig. 4, a double-tube ring member 20c is attached to the mouth 20b of the container 20. The double-tube ring member 20c has an inner wall covering the inner surface of the mouth 20b, an outer wall covering the outer surface of the mouth 20b, and a connecting wall 20d connecting the upper ends of the inner wall and the outer wall and covering the upper opening edge of the mouth 20b. A protrusion 20a extending all around is formed on the inner surface of the inner wall of the ring member 20c. The ring member 20c may be formed integrally with the mouth 20b.

[0022] As shown in Figure 3, when the outer peripheral surface of the pouring tube portion 14 is placed on the upper opening edge of the upper end of the mouth portion 20b of this container 20 via the ring member 20c, the step portion 21a of the convex peripheral wall 21 engages with the upper surface of the connecting wall 20d of the ring member 20c when the contents of the refillable container 11 are injected into this container 20. In addition, as shown in Figure 4, when the pouring tube portion 14 is inserted into the mouth portion 20b of the main container 20 and the outer surface of the convex peripheral wall 21 is abutted against or brought close to the inner surface of the inner wall of the ring member 20c, the step portion 21a of the convex peripheral wall 21 engages with the upper surface of the protrusion portion 20a of the ring member 20c when the contents of the refillable container 11 are injected into the main container 20.

[0023] As described above, according to the dispensing member 1 of this embodiment, the dispensing tube portion 14 has an approximately C-shape opening toward the other direction Y when viewed from the top-bottom direction, so that it is easy to ensure the flow path cross-sectional area of ​​the contents while keeping the size of the dispensing tube portion 14 in the other direction Y small. In this way, since the size of the pouring tube portion 14 in the other direction Y is kept small, as shown in Figure 4, when the pouring tube portion 14 is inserted into the mouth portion 20b of the container 20 and the outer peripheral surface of the convex peripheral wall 21 is abutted against or close to the inner peripheral surface of the inner peripheral wall of the ring member 20c, it is possible to ensure a wide gap between the outer peripheral surface of the concave peripheral wall 22 and the inner peripheral surface of the mouth portion 20b of the container 20.In this state, when the contents are poured out from the pouring tube portion 14, not only is it possible to make it difficult for a liquid film to form and to ensure space for air replacement within the container 20, but it is also possible to prevent the contents from dripping from the upper end opening of the pouring tube portion 14. Furthermore, as mentioned above, since it becomes easier to ensure the flow path cross-sectional area of ​​the contents in the pouring tube portion 14, clogging of the contents is suppressed and the pressing force applied to the squeezeable body portion of the refillable container 11 can be easily adjusted. As shown in Figure 3, when the outer surface of the convex peripheral wall 21 is placed on the upper opening edge of the mouth portion 20b of the main container 20 via the ring member 20c, the body is squeezed and deformed, and the contents in the refillable container 11 are injected into the main container 20, it is possible to prevent the contents poured out from the pouring tube portion 14 from overflowing from the mouth portion 20b of the main container 20. As a result, regardless of the pouring position of the refill container 11, the contents can be poured into the main container 20 without overflowing from the opening 20b.

[0024] Since the circumferential center of the concave peripheral wall 22 is located away from the central axis O in one direction X or at the same radial position, when the pouring tube portion 14 is inserted into the mouth portion 20b of the container 20 and the outer peripheral surface of the convex peripheral wall 21 is abutted against or close to the inner peripheral surface of the inner wall of the ring member 20c, a wide gap can be reliably secured between the outer peripheral surface of the concave peripheral wall 22 and the inner peripheral surface of the mouth portion 20b of the container 20.

[0025] A step portion 21a is formed on the outer peripheral surface of the convex peripheral wall 21, which engages with the connecting wall 20d or the protrusion portion 20a provided on the main container 20 when the refillable container 11 is in the pouring position, thereby stabilizing the pouring position of the refillable container 11.

[0026] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0027] For example, the step portion 21a does not need to be formed on the outer circumferential surface of the protruding peripheral wall 21. The circumferential center of the recessed peripheral wall 22 may be located away from the central axis O in the other direction Y.

[0028] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described embodiments and the above-described variations may be combined as appropriate. [Explanation of symbols]
