Note that the main part is the part as seen from the ZZ direction in Figure 4(B). [Figure 5] 5A and 5B show the state immediately after the measuring cup is attached to the cap body of the measuring cap shown in FIG. 1, where FIG. 5A is a cross-sectional view seen from the side (ZZ direction in FIG. 5B), and FIG. 5B is a cross-sectional view seen from the YY direction in FIG. 5A. BEST MODE FOR CARRYING OUT THE INVENTION
[0016] 1 to 5 show a measuring cap 1 for attachment to a container body according to an embodiment of the present invention. The measuring cap 1 comprises a cap body 2 and a measuring cup 40 . Each of these members can be made of, for example, synthetic resin. In the illustrated example shown in Figure 2, the container body 100 has a mouth / neck portion 104 standing up from a shoulder portion 102, and a receiving portion 106 for engaging with an anti-rotation locking piece 6 between the shoulder portion and the mouth / neck portion. For convenience of explanation, the basic structure of the measuring cap 1 will be explained first.
[0017] In this embodiment, as shown in FIG. 1(A), the cap body 2 has an inner peripheral wall 14 extending downward from the upper end of the mounting tube 4 for fitting into the mouth / neck portion 104 via an inward flange-shaped top wall 10, and a pouring portion 34 extending upward from a bottom wall 30 attached to the lower end of this inner peripheral wall 14.
[0018] In the illustrated example, the attachment tube 4 has an upper tubular portion 4b that stands up from a lower tubular portion 4a via a reduced diameter portion, and a threaded portion 8 is formed on the inner surface of the upper tubular portion 4b for screwing onto the mouth / neck portion 104. Further, a locking piece 6 for preventing rotation is attached to the inner surface of the lower cylindrical portion 4a for locking onto the receiving portion 106. However, these structures can be modified as appropriate.
[0019] The flange-shaped top wall 10 projects horizontally inward from the upper end of the mounting tube 4. The upper end surface of the mouth / neck portion 104 abuts against the lower surface of the flange-shaped top wall 10, as shown in FIG. In the illustrated example, a cylindrical seal portion 12 that adheres tightly to the inner surface of the mouth / neck portion 104 is provided downward from the flange-shaped top wall 10 .
[0020] The inner peripheral wall 14 is provided so as to extend downward from the inner peripheral side of the flange-shaped top wall 10 into the mouth / neck portion 104 . In this embodiment, the inner peripheral wall 14 is made up of an upper wall portion 16, an intermediate wall portion 18, and a lower wall portion 28, as shown in FIG. The upper wall portion 16 is a cylindrical peripheral wall that hangs down from the inner peripheral end of the flange-shaped top wall 10, and its inner surface is formed with a fitting hole 17 for fitting a cup cylindrical wall 44 described below. The intermediate wall portion 18 is a holding peripheral wall into which a cup barrel wall 44, which will be described later, is fitted. The retaining peripheral wall 18 is formed cylindrically so as to enable the operation described below of rotating the cylindrical wall about the cylindrical axis O when the cylindrical cup wall 44 is inserted. The peripheral holding wall 18 is suspended directly downward from the upper wall portion 16, and in this embodiment is formed to be thicker than the upper wall portion 16 and the lower wall portion 28. This thick peripheral holding wall 18 is formed with grooves 20, which will be described later. The lower wall portion 28 is formed in a tapered shape with a smaller diameter on the lower side. In the illustrated example, as shown in FIG. 1(A), a horizontal first upward step surface DU1 is formed between the inner peripheral surface of the upper wall portion 16 and the inner peripheral surface of the retaining peripheral wall 18, and a horizontal second upward step surface DU2 is formed between the inner peripheral surface of the retaining peripheral wall 18 and the inner peripheral surface of the lower wall portion 28. Furthermore, a horizontal downward step surface DL is formed between the outer peripheral surface of the peripheral holding wall 18 and the outer peripheral surface of the lower wall portion 28. On the other hand, the outer peripheral surface of the upper wall portion 16 and the outer peripheral surface of the peripheral holding wall 18 are flush with each other. However, these structures can be modified as appropriate.
[0021] The bottom wall 30 is formed as an inclined wall portion that becomes lower from one side (the left side in the figure) to the opposite side (the right side in the figure) in the horizontal direction L shown in FIG. 1(A). In this embodiment, at least in the lowest part of the bottom wall 30, a liquid collection port P2 is opened, through which liquid that has passed through a plurality of liquid guide grooves 20B, which will be described later, collects. The illustrated liquid collection port P2 opens from the lowest part of the bottom wall 30 to the adjacent part of the lower wall portion 28. However, this opening position can be changed as appropriate. A liquid passage port 32 is opened on the higher side than the liquid collection port P2, and a discharge portion 34 is provided upright along the edge of this liquid passage port 32. In this specification, the term "low" means "low position" and the term "high" means "high position". In the illustrated example, the liquid passage port 32 is continuous with the liquid collection port P2. To distinguish between these two ports, the boundary line b between the liquid passage port 32 and the liquid collection port P2 is drawn with a dashed line in Figures 1(A) and 1(B). Note that the liquid passage port 32 and the liquid collection port P2 may be formed separately. In this specification, the term "inclined wall portion" means that the wall portion is inclined to a degree that allows liquid to be guided from the lower end side of the plurality of liquid guide grooves 20B to the liquid collection port P2, and it is not necessary for the entire bottom wall 30 to be inclined. The outlet portion 34 has a role of guiding the liquid in the container body 100 so that it is poured out from the tip 36 side via the liquid passage port 32, and may have any structure as long as it fulfills this role. The pouring part 34 in the illustrated example is generally cylindrical overall, and has a slit-shaped air replacement gap 35 formed on one side (the left side in the drawing) in the horizontal direction L to facilitate pouring of liquid from the opposite side (the right side in the drawing). However, the gap 35 may be omitted and the pouring tube may be used.
[0022] As shown in FIG. 1(A), the measuring cup 40 is configured by vertically extending a cup cylindrical wall 44 from the peripheral edge side of a top plate 42, the cup cylindrical wall 44 having an opening 45 at its lower end (tip e). The cup barrel wall is mounted within the retaining peripheral wall 18. The cup cylindrical wall 44 in the illustrated example consists of an upper cylindrical portion 44a which is tapered with a small diameter on the upper side and a lower cylindrical portion 44b which is straight, and from the middle position in the vertical direction, a locking flange portion 46 for locking onto the upper surface of the flange-shaped top wall 10 protrudes outward in the cylindrical diameter direction. The upper cylindrical portion 44a is a gripping cylindrical portion that allows a user to hold the measuring cup 40 in an upside-down state, and the lower cylindrical portion 44b is a fitting cylindrical portion that is fitted (attached) within the holding peripheral wall 18. An annular abutment rib 48 is provided around the upper end of the outer circumferential surface of the lower cylindrical portion 44b, continuing from the inner circumferential portion of the locking flange portion 46. This abutment rib 48 is fitted into the fitting hole 17 in a liquid-tight manner. When the cup barrel wall 44 is attached to the peripheral holding wall 18, the tip end e thereof is in pressure contact with the second upward stepped surface DU2, except for the portion where a communication passage i, which will be described later, is formed.
[0023] In the present invention, a scraping means S for scraping off deposits on the cup barrel wall 44 is formed between the holding peripheral wall 18 and the cup barrel wall 44 . As shown in Fig. 1(A), the scraping means S is formed as at least one groove 20 provided vertically in the peripheral holding wall 18. The groove 20 shown in the figure has a pair of corner edges 26 on both sides in the width direction. In this embodiment, the groove portion 20 has a vertical slit-like portion (liquid-guiding slit 20A) that appears on the right side of the retaining peripheral wall 18, and a vertical groove-like portion (liquid-guiding groove 20B) that appears on the left side of the retaining peripheral wall 18, as shown in the cross-sectional view of Figure 1(A). In either case, the groove portion 20 is arranged facing the outer peripheral surface of the cup barrel wall 44, as shown in Figure 3(B), and the widthwise corner edge portion 26 of the groove portion 20 is arranged so as to be in close contact with the outer peripheral surface. The two types of groove portions 20 are formed so that, by rotating the measuring cup 40 relative to the cap body 2, at least the corner edge portion 26 on the rotation direction side can scrape off any adhesions A on the outer peripheral surface of the cup barrel wall 44, as shown by the arrows in the same figure. The corner edge 26 is an example of a scraping portion, and although not shown, scraping projections protruding from appropriate positions on the inner surface of the grooved rib portion may be pressed against the outer peripheral surface of the cup barrel wall 44. The scraped liquid flows down inside the grooves 20. As shown in Figure 5(A), this liquid is collected into the container body through a collection port P (in the illustrated example, an opening end P1 and a liquid collection port P2, which will be described later) provided at an appropriate position on the cap body. In this specification, "almost intimate contact" means contact (including pressure contact) so as to be able to scrape off any deposits on the cup barrel wall. "Scrape off" refers to removing foreign matter by sliding it against the outer circumferential surface of the cup barrel wall.
[0024] First, the arrangement and number of the grooves 20 in two modes will be described. In this embodiment, the liquid guide grooves 20B are arranged mainly in one half 18a of the peripheral holding wall 18 shown in FIG. 1(B), and the liquid guide slits 20A are arranged in the other half 18b. The half portion 18a is a portion that continues to the higher half portion of the bottom wall 30, which becomes lower from one side to the other in the horizontal direction, and is the portion that becomes the lower side when the container body is tilted to perform the pouring operation. On the other hand, the other half portion 18b is a portion that is continuous with the lower half portion of the bottom wall 30, and is the portion that becomes the upper side when the container body is tilted to perform the pouring operation. In FIG. 1(B), a center line C that is the boundary between the one half portion 18a and the other half portion 18b is drawn by an imaginary line. In the preferred illustrated example, five liquid guide grooves 20B are arranged in the vicinity of the one half portion 18a and the center line C, and three liquid guide slits 20A are arranged in the remaining part of the other half portion 18b. These grooves 20 are equiangularly arranged. However, the arrangement and number of these grooves can be changed as appropriate.
[0025] Next, two types of structures of the groove portion 20 will be described. The liquid guide slit 20A is an elongated hole (through hole) cut through the entire thickness of the peripheral holding wall 18 as shown on the right side of FIG. 3(A), and has a pair of inner surfaces 21a, 21b facing each other. The corner edge 26 is formed between one inner surface 21a (the closing direction side indicated by the arrow in FIG. 3(A)) and the inner peripheral surface of the cup barrel wall 44. Liquid scraped from the liquid guide slit 20A having this corner edge 26 flows down along the one inner surface 21a to reach the opening end P1 described below. This allows the flowing liquid to be guided smoothly toward the container body 100. Although not shown, a scraping protrusion (preferably a vertically long scraping protrusion) may be provided to protrude from one of the pair of inner surfaces 21a, 21b, with the tip of the protrusion coming into contact with the outer circumferential surface of the cup barrel wall 44. For example, deposits may be scraped off at two locations: the tip of the scraping protrusion and the corner edge 26. The lower end of the liquid guide slit 20A is an opening end P1 that serves as the recovery port P and opens into a part of the downward step surface DL. The liquid guide groove 20B is a vertical groove provided vertically on the inner peripheral surface of the peripheral holding wall 18, and in the illustrated example, is defined by a pair of groove side surfaces (lateral side surfaces) 22 and a groove bottom surface (lateral bottom surface) 23. A groove lower surface 24 is formed at the lower end of the liquid guide groove 20B. Therefore, the lower end is closed downward, but is inwardly connected to the liquid collection port P2 via a communication passage i formed between the lower end of the cup barrel wall 44 and the bottom wall 30, as shown in Figure 5(A). In order to form the communication passage i, the second upward step surface DU2 is formed lower in the vicinity of the groove lower surface 24 than other portions. In the configuration of the liquid guide groove 20B, for example, the tip of a scraping ridge protruding from the groove bottom surface 23 may be abutted against the outer surface of the cup barrel wall 44, and the tip of the scraping ridge may be used together with (or instead of) the corner edge portion 26 to scrape off any deposits. The structure of the grooves 20 common to the liquid guide slits 20A and the liquid guide grooves 20B will now be described. 3(A), the cross section of each groove 20 is rectangular, and the corner edges 26 of each groove 20 are right-angled. However, these shapes can be changed as needed. Each groove 20 is formed over the entire vertical length of the peripheral holding wall 18. However, this structure can be modified as appropriate, and for example, the grooves 20 may be formed only in the lower half of the peripheral holding wall 18.
[0026] In the present invention, the cup barrel wall 44 is arranged so as to be rotated relative to the holding peripheral wall 18 by a rotation mechanism R, which will be described later, when the cup barrel wall 44 is inserted into or removed from the holding peripheral wall 18. This rotational movement allows the scraping means S to scrape off the deposits A on the outer peripheral surface of the cup barrel wall 44. The rotation mechanism R is a mechanism for rotating the cup barrel wall 44 relative to the holding peripheral wall 18 . By providing the rotation mechanism R described above, each time the measuring cup 40 is reassembled to the cap body 2 after dispensing liquid, the cup barrel wall 44 is always rotated when the cup barrel wall 44 is inserted into the retaining peripheral wall 18, and any deposits are removed from the cup barrel wall 44. Therefore, unlike in the case where the user manually rotates the cup barrel wall, the user will not forget to perform the rotation operation, and the measuring cup can always be used in a clean state. The rotation mechanism R of this embodiment is a screw mechanism made up of a female screw 19 provided on the inner peripheral surface of the peripheral holding wall 18 and a male screw 50 provided on the outer peripheral surface of the cup cylindrical wall 44 .
[0027] In this embodiment, the groove portion 20 is provided so as to cross the female thread 19 of the peripheral holding wall 18. The contours of the male thread 50 and the female thread 19 are made to match each other when viewed in a cross section passing through the cylindrical axis O of the cup cylindrical wall 44, as shown in Figure 1(A). "Matched shapes" means that the cross-sectional shapes of the male and female threads are the same, and that there is no gap between them in the fitted (screwed) state that would allow the presence of adhesions. In this way, the liquid adhering to the thread groove of the male screw 50 can be finely removed by the corner edge portion located on the thread portion of the female screw, and the adhering matter can be scraped off sufficiently. However, this structure can be modified, and the grooves 20 and the rotation mechanism R may be provided in separate locations. For example, the grooves 20 may be provided in the lower half of the peripheral holding wall 18, and the rotation mechanism R may be provided in the upper half of the peripheral holding wall 18 and at corresponding locations on the cup barrel wall 44.
[0028] In the above configuration, when using the measuring cup 40, from the state shown in Figure 2, the measuring cup 40 is unscrewed from the retaining peripheral wall 18 of the cap body 2, and the measuring cup 40 is turned upside down so that the opening 45 of the measuring cup 40 faces upward. Next, the container body 100 is tilted to one side of the horizontal direction L (to the left side in the figure), and liquid is poured from the pouring portion 34 into the opening 45. At the end of this pouring operation, some of the liquid may flow down from the tip e of the measuring cup 40 along the outer surface of the cup barrel wall 44 and adhere to part of the outer surface of the cup barrel wall 44, mainly the part between the tip e and the locking flange 46 (the outer surface of the mating barrel portion 44b). Furthermore, since the flowing liquid stops at the male thread 50 and the locking flange 46 of the measuring cup 40, there is little chance that the liquid will get on the hands of a user who is holding the gripping tube portion 44a, which is located below the locking flange 46, in the inverted state.
[0029] After the dispensing operation is completed, the measuring cup 40 is turned upside down again, and the lower cylindrical portion 44 b of the cup cylindrical wall 44 is threaded down into the holding peripheral wall 18 . As shown in Figures 3(A) and 4(A), as the cup barrel wall 44 gradually descends, the groove portion 20 (mainly the corner edge portion 26 of the groove portion) gradually scrapes off the deposits A on the cup barrel wall 44, as shown in Figures 3(B) and 4(B). The scraped off deposit A is liquid, so it flows down inside the grooves 20 and is collected into the container body 100 via the two collection ports P shown in FIG. 2 in this embodiment. In the liquid guide slit 20A of the two modes of the recessed streak portion 20, the liquid that flows down the inner surface 21a thereof drips into the container body 100 through the open end P1, which is the lower end of the liquid guide slit 20A. On the other hand, in the liquid guide groove 20B, the liquid scraped off mainly by the corner edge portion 26 flows down along the inner surface of the groove, reaches the groove lower surface 24, and then flows through the communicating passage i onto the bottom wall 30 inclined from one side of the horizontal direction L to the other side. The liquid that has passed through the communication passages i of the plurality of liquid-guiding grooves 20B flows downward on the bottom wall 30, joins together in sequence, and is collected at the liquid collection port P2, from which it is recovered into the container body 100 side.
[0030] According to the above configuration and function, the cup barrel wall 44 of the measuring cup 40 is attached within the retaining peripheral wall 18 of the cap body 2, and in order to scrape off any deposits between the retaining peripheral wall 18 and the cup barrel wall 44, a liquid-guiding groove portion 20 facing the cup barrel wall 44 is vertically provided on the retaining peripheral wall 18.Therefore, the groove portion 20 (mainly the corner edge portion 26 of the groove portion) can be used to accurately remove any deposits A on the outer surface of the cup barrel wall 44. Furthermore, the cup barrel wall 44 is formed so as to be attached to the retaining peripheral wall 18 by inserting it into the retaining peripheral wall 18 and rotating it, so that any adhesions on the cup barrel wall 44 can be reliably scraped off and removed each time the cup barrel wall 44 is attached to the retaining peripheral wall 18. Furthermore, a screw mechanism consisting of a male screw 50 formed on the cup barrel wall 44 side and a female screw 19 formed on the holding peripheral wall 18 side is provided as a rotation mechanism R for rotating the cup barrel wall 44 relative to the holding peripheral wall 18, and the groove portion 20 is provided so as to run vertically through the female screw 19 of the holding peripheral wall 18, so that the contents can be removed accurately. Furthermore, as the groove portion 20, a liquid guide slit 20A is provided in at least a part of the retaining peripheral wall 18 by cutting the retaining peripheral wall 18 vertically, and in order to recover the liquid flowing down the liquid guide slit 20A to the container body 100 side, the lower end of the liquid guide slit 20A is made into an opening end P1 which is a recovery port for the liquid, so that the liquid can be smoothly recovered to the container body 100 side.
