  Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings.

Example 1 (FIGS. 1 to 5)
The measuring cap 100 according to the first embodiment shown in FIGS. 1 to 3 is detachably attached to the mouthpiece 11 of a container body 10 made of a synthetic resin bottle containing a liquid detergent as a content liquid, for example. The measuring cap 100 has a scale drawn on the outer peripheral surface or the inner peripheral surface, and can measure an appropriate amount of liquid detergent poured out from the container body 10 and put it into a washing machine or the like.

  In the present specification, in a state where the measuring cap 100 is attached to the neck portion 11 of the container main body 10, the container main body 10 side is set to the “lower” side, and the measuring cap 100 side is set to the “upper” side. .

  In the present embodiment, a main body cap 20 is attached to the neck portion 11 of the container body 10, and the measuring cap 100 is screwed to the main body cap 20 and attached to the mouth portion 11 of the container body 10.

  The main body cap 20 is a well-known one having substantially the same configuration as the main body cap described in, for example, Japanese Patent Application Laid-Open No. 2001-139049, and a spout 32 provided in a liquid return cylinder portion 31 described later of the measuring cap 100 is provided above A recess 21 for liquid recovery that can be inserted and disposed inside.

  As shown in FIG. 4, the main body cap 20 protrudes upward from the ceiling portion 23 of the skirt wall portion 22 that covers the mouth portion 11 of the container main body 10 and is smaller than the skirt wall portion 22. A male screw wall portion 24 that is concentrically arranged in diameter and has a male screw portion 25 formed on the outer peripheral surface thereof, and extends downward from the lower end portion of the male screw wall portion 24 along the inner peripheral surface of the mouth 11. In addition, it has a bowl-shaped saucer portion 27 having a bottom opening plate 26 inclined obliquely. Further, as shown in FIG. 1, when the measuring cap 100 provided so as to protrude upward from the central portion of the tray portion 27 and in which the liquid return cylindrical portion 31 is inserted and disposed in the liquid recovery concave portion 21, the liquid return cylindrical portion is attached. 31 has a dispensing nozzle 28 disposed inside.

  The skirt wall portion 22 has an engaging uneven portion 29 on the inner peripheral surface of the lower end portion. The main body cap 20 is pushed into the mouth 11 of the container body 10, and the engaging uneven portion 29 is formed on the base of the mouth portion 11. The main body cap 20 is attached and fixed to the mouth 11 of the container main body 10 by being engaged with the engaged irregularities 12 formed on the outer peripheral surface of the end. Further, a female screw portion 35 formed on a skirt-like annular wall 34 of the measuring cap 100 described later is screwed into the male screw portion 25 of the male screw wall portion 24, and the male screw wall portion 24, together with the saucer portion 27, A recess 21 for liquid recovery is formed on the substrate.

  The saucer portion 27 is a bowl-shaped portion that is inserted and arranged inside the mouth neck portion 11 of the container body 10, and the bottom opening plate 26 that is inclined obliquely is positioned at the lowest portion thereof and is a liquid return opening. 26K is formed. When the measuring cap 100 is remounted, the excess liquid recovered from the measuring cap 100 to the liquid recovery recess 21 can be returned to the inside of the container body 10 through the liquid return opening 26K. Yes. In addition, a pouring nozzle 28 is provided at a central portion away from the peripheral portion of the bottom opening plate 26 so as to protrude from the bottom opening plate 26 to above the male screw wall portion 24. The pouring nozzle 28 has substantially the same form as the pouring cylinder described in, for example, Japanese Patent Application Laid-Open No. 2001-139049, and communicates with an outflow opening 28K formed in the bottom opening plate 26 at the base end portion thereof. The liquid detergent can be smoothly poured out into the measuring cap 100 through the tip spout 28L whose sectional shape is smaller than the spout 32 of the measuring cap 100.

  The measuring cap 100 includes two members, a lower member 30 and an upper member 40 that are divided into upper and lower parts. For example, the lower member 30 and the upper member 40 are both formed by injection molding of synthetic resin, and have a shape designed so that the mold can be easily removed during injection molding. The synthetic resin forming the lower member 30 and the upper member 40 is preferably transparent or translucent from the viewpoint of the visibility of the content liquid poured into the measuring cap 100.

  The lower member 30 has a liquid return cylinder portion 31 provided with a spout 32 on the lower end side. When the measuring cap 100 is attached to the main body cap 20, the spout 32 of the liquid return cylinder portion 31 is inserted into the inner side of the main body cap 20 (in this embodiment, the liquid recovery recess 21 of the main body cap 20) from above. .

  The upper member 40 has a dome-shaped liquid reservoir 41 that is attached to the liquid return cylinder 31 of the lower member 30. The liquid reservoir 41 has an inner diameter D2 that is larger than the inner diameter D1 of the liquid return cylinder 31 of the lower member 30 (FIG. 1). Thus, by comprising the measuring cap 100 with two members of the lower member 30 and the upper member 40, the diameter of the spout 32 provided in the lower member 30 is not limited by the die-cutting property when the measuring cap 100 is molded. The lower member 30 having a diameter reduced so that the upper member 40 can be inserted into the main body cap 20 can be formed, while the diameter of the liquid reservoir 41 formed by the upper member 40 is increased to increase the liquid reservoir capacity. Can be molded. Therefore, it is possible to secure a large liquid storage capacity in the liquid storage part 41 of the measuring cap 100 without increasing the diameter of the neck part 11 or the main body cap 20 of the container body 10.

  The lower member 30 and the upper member 40 constitute the measuring cap 100 by fitting and joining the upper member 40 to the outside of the upper outer peripheral surface of the lower member 30. The measuring cap 100 configured in this manner is provided integrally with the liquid return cylinder part 31 inserted into the liquid recovery recess 21 of the main body cap 20 and the liquid return cylinder part 31 when being attached to the main body cap 20. And a liquid reservoir 41 disposed above the main body cap 20. In addition, the outer peripheral surface of the measuring cap 100 is formed by the upper member 40 when attached to the main body cap 20.

  As shown in FIGS. 4 and 5, the lower member 30 includes a liquid return cylinder portion 31 that is a cylindrical portion, an annular rib 33 that protrudes outward from the upper end portion of the liquid return cylinder portion 31 when mounted, and an annular rib 33. The skirt-like annular wall 34 having a female threaded portion 35 on the inner peripheral surface is provided concentrically with the liquid return cylinder portion 31 and is suspended from the outer peripheral edge portion of the body cap 20. The measuring cap 100 is detachably attached to the mouthpiece 11 by being screwed into the male screw portion 25 of the male screw wall portion 24 in FIG. As will be described later, the annular wall 34 is inserted into the inner peripheral portion on the lower end side of the liquid reservoir 41 in the upper member 40.

  That is, in the present embodiment, the female screw portion 35 provided on the annular wall 34 of the lower member 30 is screwed to the male screw portion 25 provided on the main body cap 20. As a result, the female screw portion 35 of the lower member 30 is screwed into the male screw portion 25 outside the main body cap 20 apart from the liquid return cylinder portion 31, and the content liquid measured by the measuring cap 100 is poured. When the female screw part 35 of the lower member 30 is screwed onto the male screw part 25 of the main body cap 20 after the delivery, even if the liquid content leaks from the spout 32 of the lower member 30 to the outer peripheral surface of the liquid return cylinder part 31, It is possible to effectively avoid the content liquid from adhering to the female screw portion 35 and to avoid finger smearing when the measuring cap 100 is attached / detached. In addition, since the female screw portion 35 of the lower member 30 is provided on the annular wall 34 fitted inside the joining skirt portion 42 having no step on the outer periphery as will be described later, the metering provided with the female screw portion 35 is provided. The cap 100 is made compact without expanding the outer periphery, and the amount of synthetic resin is small.

  In the lower member 30, when the measuring cap 100 is screwed into the liquid return cylinder portion 31 until the lower surface of the annular rib 33 comes into contact with the upper end of the male screw wall portion 24 of the body cap 20, It is provided with a length arranged near the bottom opening plate 26 of the portion 27. Further, when the measuring cap 100 is screwed and attached to the main body cap 20, the lip 32 </ b> A formed in an annular shape at the opening peripheral portion of the spout 32 is a contact step formed on the inner peripheral surface of the tray portion 27. This prevents the liquid detergent contained from coming into the gap between the liquid recovery recess 21 on the outside of the liquid return cylinder part 31 and improves the sealing performance. It is improving. The lip 32A of the spout 32 improves the above-mentioned adhesion to the contact step portion 27A of the tray portion 27, improves the liquid drainability when the content liquid is poured out from the measuring cap 100, and prevents liquid dripping. There is also an effect.

  Further, the spout 32 of the liquid return cylinder portion 31 protrudes in a straight shape toward the inside of the main body cap 20. Accordingly, when the female screw portion 35 of the lower member 30 is screwed into the male screw portion 25 of the main body cap 20, the spout 32 of the liquid return cylinder portion 31 of the lower member 30 starts to be inserted into the inner side of the main body cap 20. The spout 32 that protrudes in a shape is guided by the inner surface of the main body cap 20, and the measuring cap 100 is coaxial with the central axis of the main body cap 20, so that the slanting is avoided and the screwing is easy and reliable. Can be achieved.

  In the lower member 30, the annular rib 33 is an annular band plate portion that connects the upper end portion of the liquid return cylinder portion 31 and the upper end portion of the annular wall 34, and a contact ring 36 projects downward on the lower surface thereof. Is provided. The measuring cap 100 is attached to the main body cap 20 while the contact ring 36 is in pressure contact with the upper end surface of the male screw wall portion 24 of the main body cap 20. Thereby, when the measurement cap 100 is attached to the neck part 11, the liquid sealing property of the content liquid of the container body 10 with respect to the outside can be secured.

  The lower member 30 has a cylindrical wall 37 that is provided at the upper end portion of the liquid return cylinder portion 31 and rises upward from an intermediate portion of the strip width along the radial direction of the annular strip portion of the annular rib 33. As will be described later, the cylindrical wall 37 is inserted into the inner peripheral portion of the upper end side of the liquid reservoir 41 in the upper member 40. Therefore, in this embodiment, the cylindrical wall 37 forms the inner peripheral surface of the liquid reservoir 41.

  As shown in FIG. 5, the upper member 40 includes a celestial cylindrical liquid reservoir portion 41, and a joining skirt portion 42 that is slightly expanded in inner diameter from the lower end portion of the liquid reservoir portion 41 and extends downward. Consists of.

  The outer peripheral portions of the cylindrical wall 37 and the annular wall 34 of the lower member 30 are inserted into the inner peripheral portions of the liquid reservoir portion 41 and the joining skirt portion 42 of the upper member 40.

  At this time, a knurl-like locking portion 38 is provided in the entire region (or a plurality of locations) in the circumferential direction of the outer peripheral portion of the lower end of the cylindrical wall 37 in the lower member 30, and the inner periphery of the lower end of the liquid reservoir portion 41 in the upper member 40. A knurled locking portion 43 is provided in the entire area (or a plurality of locations) in the circumferential direction of the portion (FIG. 5B). When the upper member 40 is fitted and joined to the outside of the upper outer peripheral surface of the lower member 30, the knurled locking portion 43 of the upper member 40 is fitted into the knurled locking portion 38 of the lower member 30 while being locked, The lower member 30 and the upper member 40 are locked in the circumferential direction. Thereby, the lower member 30 and the upper member 40 have a structure that is difficult to rotate, and are joined so as to be able to be prevented from rotating, and the joining strength in the circumferential direction of the lower member 30 and the upper member 40 in the measuring cup 100 can be ensured.

  As described above, when the female screw portion 35 provided on the lower member 30 is screwed to the male screw portion 25 provided on the main body cap 20, the knurl-like locking portion 38 of the lower member 30 and the knurl of the upper member 40. The locking structure in the circumferential direction with the shaped locking portion 43 ensures transmission of the screw operation force applied to the upper member 40 held by the user's fingers to the lower member 30.

  Further, a convex engaging portion 39 that is continuous in the circumferential direction is provided on the outer peripheral portion of the lower end of the annular wall 34 in the lower member 30, and is continuous in the circumferential direction on the inner peripheral portion of the lower end of the joining skirt portion 42 in the upper member 40. A concave engaging portion 44 is provided. When the upper member 40 is fitted and joined to the outside of the upper outer peripheral surface of the lower member 30, the concave engagement portion 44 of the upper member 40 is moved through elastic deformation of the lower end opening of the joining skirt portion 42 of the upper member 40. The lower member 30 is engaged with the convex engaging portion 39 of the lower member 30, and the lower member 30 and the upper member 40 are engaged in the vertical direction. As a result, the lower member 30 and the upper member 40 are structured to be difficult to come off, and are joined so as to be prevented from coming off, and the joining strength in the vertical direction of the lower member 30 and the upper member 40 in the measuring cap 100 can be secured.

  In the measuring cap 100, when the lower member 30 and the upper member 40 are joined and integrated, the inner peripheral surface of the lower member 30, the inner peripheral surface and the top surface inside of the upper member 40 become a part for storing the liquid detergent, A scale for measurement is appropriately drawn on the inner peripheral surface or outer peripheral surface of the liquid return cylindrical portion 31 and the cylindrical wall 37 of the lower member 30 or the inner peripheral surface or outer peripheral surface of the liquid reservoir 41 of the upper member 40.

  Further, when the lower member 30 and the upper member 40 are joined and integrated, the standing tip 37K of the cylindrical wall 37 raised from the upper end portion of the liquid return cylindrical portion 31 of the lower member 30 is the liquid reservoir 41 of the upper member 40. Is inserted into an annular seal groove 45K provided on the top surface of the liquid and sealed in a liquid-tight manner. The annular seal groove 45 </ b> K is formed by forming an annular gap between the annular rib 46 projecting from the inner surface of the liquid reservoir 41 and the inner peripheral portion on the upper end side of the liquid reservoir 41. In the present embodiment, the inner peripheral surface of the standing tip 37K of the cylindrical wall 37 in the lower member 30 is in pressure contact with the outer peripheral surface of the annular rib 46 provided on the top surface of the liquid reservoir 41 in the upper member 40 to be liquid-tight. Sealed. Thereby, when the measuring cap 100 is attached to the main body cap 20, the liquid sealability of the content liquid in the container main body 10 to the outside can be secured. Moreover, when the content liquid poured out from the container main body 10 is measured to the measurement cap 100 removed from the container main body 10, the liquid sealing property with respect to the outside of the content liquid measured by the measurement cap 100 is securable.

  However, the upper member 40 constituting the measuring cap 100 has an outer peripheral surface as a continuous surface 47 continuous over the entire length in the vertical direction. In the present embodiment, the outer peripheral surface of the upper member 40 has a reduced diameter that continuously forms a small taper from the lower end side toward the upper end side so that the mold can be easily removed during injection molding. When the measuring cap 100 is attached to the main body cap 20, the lower end portion (joining skirt portion 42) of the outer peripheral surface of the upper member 40 is opposed to the ceiling portion 23 of the skirt wall portion 22 of the main body cap 20 through a small gap in the vertical direction. The joint skirt portion 42 and the ceiling portion 23 that face each other and face each other are set to have substantially the same outer diameter (FIG. 4). Thereby, the joining skirt part 42 and the ceiling part 23 form a continuous shape in the vertical direction.

  That is, in the measuring cap 100, the outer peripheral surface of the liquid reservoir portion 41 of the upper member 40 and the outer peripheral surface of the joining skirt portion 42 are fitted and joined to the outside of the upper outer peripheral surface of the lower member 30 without any step in the vertical direction. The outer circumferential surface of the upper member 40 forms a continuous surface 47 that extends over the entire length in the vertical direction, and does not form a stepped portion. Therefore, when the user grasps the measuring cap 100, the user holds the upper member 40 by placing his / her finger on the continuous surface 47 having no step portion over the entire length of the upper member 40 in the vertical direction. Compared with the case where a finger is placed on the stepped portion on the outer periphery of the measuring cap 100 and grasped, it becomes easier to grasp and the measuring workability by the user can be improved.

  In addition, since the outer peripheral surface of the upper member 40 is a continuous surface 47 having no stepped portion, the simultaneous printing workability of the measurement scales at a plurality of locations including the upper end side to the lower end side of the liquid reservoir portion 41 of the upper member 40 is achieved. Will improve. That is, it becomes easy to give scales to various portions of the measuring cap 100 in a wide range from the upper end side to the lower end side of the liquid reservoir 41, and the measuring workability by the user can be improved.

  Further, when the measuring cap 100 is screwed to the main body cap 20, the joining skirt portion 42 provided at the lower portion of the upper member 40 of the measuring cap 100 and the main body cap 20 are set to have substantially the same outer diameter. Thus, the presence of the continuous surface 47 having no step portion on the outer peripheral surface of the upper member 40 enhances the sense of unity between the measuring cap 100 and the main body cap 20.

  The upper member 40 is provided with knurls 48 at a plurality of locations (three locations in FIG. 3) on the outer peripheral surface thereof, and the measuring cap 100 is screwed onto the male screw portion 25 of the male screw wall portion 24 of the main body cap 20. The user can easily apply the screwing operation force to the outer peripheral surface of the upper member 40.

Due to the structure that engages with the annular engagement groove portion 52, the structure is made difficult to come off and is joined so as to be prevented from coming off. The annular engagement portion 51 of the lower member 30 and the annular engagement groove portion 52 of the upper member 40 are fitted and engaged through elastic deformation of the opening of the joining skirt portion 42 in the upper member 40. Thereby, the joining strength of the up-down direction of the lower member 30 and the upper member 40 in the measurement cap 300 is securable.

  Further, the measuring cap 300 and the main body cap 20 are provided with a female screw portion 53 provided on the inner peripheral surface of the joining skirt portion 42 extending from the lower end portion of the liquid reservoir portion 41 of the upper member 40 in the main body cap 20. It is assumed that it is screwed to the male screw part 25. Thereby, after the content liquid weighed by the measuring cap 300 is poured out, when the female screw part 53 of the upper member 40 is screwed to the male screw part 25 of the main body cap 20, the liquid return cylinder part 31 from the spout 32 of the lower member 30. Even when the content liquid spills on the outer peripheral surface, it is possible to effectively avoid the content liquid from adhering to the female threaded portion 53 and to prevent the finger from becoming dirty when the measuring cap 300 is attached or detached.

  The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the lower member and the upper member of the measuring cap do not necessarily have a cylindrical shape, and do not necessarily need to be screwed and attached to the mouthpiece or the body cap via the male screw portion or the female screw portion. Further, the measuring cap may be directly attached to the mouth without interposing the main body cap, and it is not always necessary that the pouring nozzle is provided in the main body cap. Further, in the second embodiment, the annular wall 34 and the internal thread portion 35 are removed as in the third embodiment, and the lower member 30 and the upper member 40 are formed on the outer peripheral edge portion of the annular rib 33 in the lower member 30. The joining portion 51 and the annular engagement groove portion 52 provided on the inner peripheral portion of the upper end of the joining skirt portion 42 in the upper member 40 may be joined so as to be prevented from coming off.

  Further, the content liquid stored in the container body is not particularly limited, and may be various other liquid products that require metering such as a softener and a bleaching agent in addition to the liquid detergent.

  According to the present invention, it is possible to improve the metering workability by the user in the measuring cap formed by joining the lower member having the liquid return cylinder portion and the upper member having the liquid reservoir portion. .
