Description

  The present invention relates to a measuring cap, and more particularly, to a measuring cap that is detachably attached to a main body cap having a liquid recovery concave portion attached to a mouth portion of a container main body.

  For example, containers containing liquid detergent or the like as content liquids may be used while measuring these content liquids, and it is cumbersome to use a measuring cup or the like separately. 2. Description of the Related Art A measuring cap having a function attached to a mouth part of a synthetic resin bottle container or the like is known. The measuring cap is provided with a scale or the like so that an appropriate amount can be easily measured in accordance with the type and amount of liquid used. In addition, when the metered cap is again attached to the mouth after pouring out the weighed content, the spout of the metering cap is placed upward so that the remaining liquid can be collected. It is known that a body cap having a recess for collecting liquid that can be inserted from is attached to the neck, and a measuring cap is attached to the body cap while a spout is inserted into the recess for collecting liquid ( For example, see Patent Document 1).

Further, in the container described in Patent Document 1, the measuring cap has a skirt-shaped liquid receiving portion on the outer peripheral portion of the measuring cylinder portion, and is tilted when the measured content liquid is poured out by inclining the measuring cap. When the liquid is returned to the state and stopped from pouring, the liquid that spills outside the spout can be received by the skirt-shaped liquid receiver, effectively preventing the area around the measuring cap from becoming dirty. (For example, refer to Patent Document 1).
JP 2000-128207 A

  In the measuring cap described in Patent Document 1, a female screw is formed on the inner side surface of the skirt-shaped liquid receiving portion. By screwing this female screw into a male screw formed on the male screw wall of the main body cap, The skirt-shaped liquid receiving part is fitted to the main body cap by external fitting, and the content liquid received by the skirt-shaped liquid receiving part is stored together with the remaining content liquid in the measuring cylinder part through the liquid recovery recess. However, when the measured inner solution is poured out, the skirt-shaped liquid receiving part may sometimes get in the way. That is, for example, in recent years, with the spread of automatic washing machines, it may be necessary to pour content liquids such as measured liquid detergent into a small liquid inlet, and the measuring cap is directed toward such a small liquid inlet. If the content liquid is to be poured while the point is tilted, the skirt-shaped liquid receiving part that protrudes greatly from the outer peripheral part of the measuring cylinder part is obstructed, and it is difficult to pour out accurately to a specific part.

  In addition, the internal solution received by the skirt-shaped liquid receiving portion directly touches and adheres to the female screw formed on the inner surface of the skirt-shaped liquid receiving portion, and the measuring cap is attached to the main body cap. Then, the content liquid adhering to the female screw is sandwiched and held between the male screw wall. For this reason, the retained internal solution is solidified, causing powder falling when the measuring cap is attached or detached, or the content liquid on the outer peripheral surface of the male screw wall that is easily touched by the hand or fingers when the measuring cap is removed. May adhere to the hands and fingers touching the outer peripheral surface. From these facts, further improvement of the measuring cap is desired.

  The present invention makes it possible to easily pour out the content liquid from the spout by setting a point while tilting the measuring cap, and to prevent the internal solution from adhering to the screwed portion between the skirt-shaped liquid receiving portion and the main body cap.

The pouring nozzle 28 communicates with an outflow opening 30 formed in the bottom plate 26 at the base end portion thereof, and through a tip pouring port 31 whose sectional shape is smaller than the pouring port 14 of the measuring cap 10. The content liquid can be smoothly poured into the measuring cap 10.

  In the present embodiment, the measuring cap 10 detachably attached to the main body cap 13 is composed of two members, that is, a lower member 23 and an upper member 24 formed by injection molding of a transparent synthetic resin, for example, as described above. It is configured. Each of the lower member 23 and the upper member 24 has a shape designed so that the mold can be easily pulled out at the time of injection molding. The lower member 23 and the upper member 24 are joined and integrated via an annular joint 32 after molding, thereby a liquid return cylinder portion 21 inserted and disposed in the liquid recovery recess 20 of the main body cap 13 at the time of mounting, and a liquid return The measuring cap 10 including the liquid reservoir bulging portion 22 that is connected to the cylindrical portion 21 and disposed above the main body cap 13 is formed.

  The lower member 23 has a liquid return cylinder portion 21 that is a hollow, substantially truncated cone-shaped portion whose inner diameter gradually increases from the inner diameter D2 of the spout 14 toward the liquid reservoir bulging portion 22, and the liquid return cylinder. It has the tight junction cylinder part 33 extended in a cylindrical shape from the base end part of the part 21. FIG. On the lower member 23, a scale for measurement is appropriately drawn on the outer peripheral surface or the inner peripheral surface.

  The tightly bonded tubular portion 33 is closely fitted so as to be fitted along the inner peripheral surface of the height region of the substantially half of the opening side of the peripheral wall of the liquid bulging portion 22 by the upper member 24, and the inner peripheral surface At the same time, a strong annular joint 32 is formed. An annular rib 34 that is continuous in the circumferential direction is provided on the outer peripheral surface of the boundary portion between the liquid return cylinder portion 21 and the tightly bonded cylinder portion 33 so as to protrude outward. Furthermore, in this embodiment, the opening peripheral part of the spout 14 of the liquid return cylinder part 21 is provided with the trumpet mouth shape which curves so that it may fold outward. Since the opening peripheral portion of the spout 14 has a trumpet shape, liquid drainage at the peripheral portion of the opening after pouring the content liquid from the measuring cap 10 is surely and easily performed. It becomes possible to avoid the wraparound of the liquid more effectively. Moreover, the operation | work which concentrates the content liquid on the part which adhered dirt etc. becomes easy.

  The upper member 24 is connected to a liquid reservoir bulging portion 22 having a substantially bottomed cylindrical shape and an opening-side end portion of the liquid reservoir bulging portion 16 via a step connection portion 35. And a cylindrical skirt-shaped liquid receiving portion 16 that is slightly larger than the inner diameter D3.

  The liquid pool bulging portion 22 is fitted along the inner peripheral surface of the liquid reservoir bulging portion 22 until the tightly bonded cylindrical portion 33 of the lower member 23 makes the annular rib 34 contact the opening end surface of the liquid pool bulging portion 22. The metering cylinder part 15 is formed together with the liquid return cylinder part 21 in connection with the liquid return cylinder part 21. The liquid reservoir bulging portion 22 is a portion that mainly stores the inner solution to be weighed, and the inner diameter D3 thereof is the inner diameter D2 of the spout 14 of the liquid return cylinder portion 21 and the inner diameter of the neck 11 of the container body 12. It is larger than D1 and is formed so as to have an outer diameter large enough to fit within a region surrounded by the skirt wall portion 25 and the female screw wall 18 of the main body cap 13 when viewed from above.

  When the upper member 24 is joined and integrated with the lower member 23, the skirt-shaped liquid receiving portion 16 is concentrically spaced from the base end side of the liquid return cylinder portion 21 to the outside of a substantially half height portion. A liquid receiving recess 36 that is arranged and is annularly continuous with the outer peripheral surface of the liquid return cylinder portion 21 is formed. The skirt-shaped liquid receiving portion 16 is formed with a male screw 17 that is screwed into the female screw wall 18 of the main body cap 13 on the outer surface thereof, and is similar to the female screw wall 18, for example, about 5.0 to 20 mm. The height H3 is provided.

  In the present embodiment, the projecting end portion 16a of the skirt-shaped liquid receiving portion 16 is brought into contact with the ceiling portion 25a of the skirt wall portion 25 of the main body cap 13, and the upper end of the female screw wall portion 18 is set to the step of the measuring cap 10. When the skirt-shaped liquid receiving portion 16 is screwed into the female screw wall 18 until it is brought into contact with the outer overhanging portion of the connecting portion 35, the opening peripheral portion of the spout 14 is the lower inner peripheral surface of the tray portion 27 of the main body cap 13. The liquid return cylinder portion 21 is formed so as to have a height H <b> 2 that comes into close contact with the contact step portion 37 formed on the surface. As a result, the sealing function for preventing the contained content liquid from flowing into the clearance between the liquid recovery recess 20 outside the liquid return cylinder portion 21 is effectively exhibited.

  Here, the height from the step connection portion 35, which is a joint portion of the skirt-shaped liquid receiving portion 16, to the spout 14 by the liquid return cylindrical portion 21 of the measuring tube portion 15 (the measuring tube portion 15 and the skirt-shaped liquid receiving portion 16. The height H2 from the boundary portion to the end of the spout 14 is preferably 1.5 times or more the height H3 of the skirt-shaped liquid receiving portion 16. Since the height H2 from the joint portion of the skirt-shaped liquid receiving portion 16 to the lower end portion of the spout 14 is 1.5 times or more the height H3 of the skirt-shaped liquid receiving portion, the skirt-shaped liquid receiving portion The distance between the lower end of 16 and the lower end of the spout 14 can be designed to be wide enough to recover the liquid, and the pouring ability to the inlet of an automatic washing machine is improved. Is done. That is, when the space between the lower end of the skirt-shaped liquid receiving portion 16 and the lower end of the spout 14 is narrow, the liquid is held between both ends by the viscosity or surface tension of the liquid, and the skirt Although it is difficult for the liquid to be collected in the liquid receiver 16, the liquid dripped from the spout 14 can be removed by providing a distance between the end of the skirt-shaped liquid receiver 16 and the end of the spout 14 as described above. While easily flowing into the liquid receiving recess 36 along the outer peripheral surface of the liquid return cylinder portion 21, the skirt-like liquid return portion 16 is less protruded in the circumferential direction and has good pouring properties to the inlet of an automatic washing machine or the like. Can be.

  According to the measuring cap 10 of the present embodiment having the above-described configuration, it is possible to determine the point while tilting the measuring cap 10 and to easily pour out the content liquid from the spout 14, and to use the skirt-shaped liquid receiving portion 16. It is possible to prevent the internal solution from adhering to the screwed portion between the main body cap 13 and the main body cap 13.

  According to the present embodiment, the male screw 17 is formed on the outer peripheral surface 16 b of the skirt-shaped liquid receiving portion 16, and the male screw 17 is screwed into the female screw 19 formed on the female screw wall 18 of the main body cap 13. By doing so, the skirt-shaped liquid receiving part 16 is attached to the main body cap 13 by internal fitting. Since the annular wall (screw wall or the like) of the main body cap 13 is not inserted and arranged on the inner peripheral side of the skirt-shaped liquid receiving portion 16, the space between the inner peripheral surface of the skirt-shaped liquid receiving portion 16 and the outer peripheral surface of the measuring cylinder portion 15 is not provided. The distance can be short. Therefore, the amount of protrusion of the skirt-shaped liquid receiving portion 16 is larger than that of the conventional case where the female screw formed on the inner peripheral surface of the skirt-shaped liquid receiving portion is screwed to the male screw wall of the main body cap by external fitting. This makes it possible to bring the spout 14 closer to the point to be poured out when the content liquid is poured into the liquid inlet while the measuring cap 10 is tilted. Can be improved.

  Further, since the male screw 17 that is a screwed portion with the main body cap 13 is formed on the outer peripheral surface 16b of the skirt-like liquid receiving part 16, the content liquid received by the skirt-like liquid receiving part 16 is the male screw. This prevents the content liquid held in the screwed portion from solidifying and causing powder falling or the like, and prevents the liquid content from dripping from being provided in the main body cap 13. Since it does not adhere to the outer peripheral surface of the female screw wall 18, there is no possibility that the hand or finger touching the outer peripheral surface will be soiled.

  Further, in the present embodiment, the measuring cylinder 15 is inserted into the liquid recovery recess 20 of the main body cap 13 at the time of mounting, and the liquid return recess 21 connected to the liquid return cylinder 21 is connected. When it is formed with the liquid reservoir bulging portion 22 having an inner diameter D3 larger than the inner diameter D2 of the spout 14 disposed above, the protruding length of the measuring cylinder portion 15 from the neck 11 is excessively increased. It is possible to easily increase the capacity that can be measured by the measuring cap 10 by increasing the capacity of the liquid reservoir without increasing the size and without expanding the diameter of the neck 11 and the main body cap 13 in the transverse direction.

  In the present embodiment, the content liquid collected in the liquid receiving recess 36 between the outer peripheral surface of the liquid return cylinder part 21 and the skirt-like liquid receiving part 16 by liquid dripping to the outside of the spout 14 is measured by the measuring cap. When 10 is fitted to the main body cap 13, the liquid may be accumulated by being held on the upper surface of the ceiling portion 25 a of the skirt wall portion 25 due to the surface tension or viscosity of the content liquid. Therefore, as shown in FIG. 2, the upper surface of the ceiling portion 25a of the skirt wall portion 25 is obliquely upward from the inside (preferably from the upper end of the liquid recovery recess 20) toward the inner peripheral surface of the skirt-shaped liquid receiving portion 16. It is preferable that a thin spatula scraper 38 made of an elastic member that stands up is provided in an annular shape. The scraper spatula 38 is attached to the inner peripheral surface of the skirt-shaped liquid receiving portion 16 with the tip portion slidingly contacting the inner peripheral surface of the skirt-shaped liquid receiving portion 16 when the measuring cap 10 is fitted to the main body cap 13. Scrape off the liquid. The scraped content liquid easily flows from the inclined surface 38 a on the upper surface side of the scraper spatula 38 to the liquid recovery recess 20. Further, when the measuring cap 10 is screwed into the main body cap 13, the scraper 38 is brought into contact with the inner peripheral surface of the skirt-shaped liquid receiving portion 16 of the measuring cap 10 to obtain an appropriate click feeling. You can feel the last sensation.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the measuring cylinder part includes a liquid return cylinder part that is inserted and disposed in the liquid recovery recess part of the main body cap, and a liquid reservoir bulge part that is connected to the liquid return cylinder part and disposed above the liquid recovery recess part. It does not necessarily have to be, and it may be a bottomed cylindrical measuring tube portion that does not include a liquid reservoir bulge portion. Further, the content liquid contained in the container body and weighed may be a liquid detergent, a softener, a paste, and other various liquid products that require weighing. Furthermore, the measuring cap does not necessarily have to be formed by joining and integrating the lower member and the upper member formed by injection molding via the annular joint, and the annular joint is, for example, above the upper end of the lower member. The member may be screw-fitted.

It is sectional drawing of the mounting state to the mouth part of a container main body explaining the structure of the measurement cap which concerns on preferable one Embodiment of this invention. It is the A section enlarged view of FIG. 1 explaining the other preferable aspect in the ceiling part of the skirt wall part of the measurement cap which concerns on preferable one Embodiment of this invention.
