Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a liquid pouring cap made of synthetic resin.

[Prior Art] As shown in FIGS. 7 and 8, a peripheral wall 3 to be screwed to the container body neck portion 2 is vertically provided from the lower surface of the top plate 4 having a larger outer diameter than the peripheral wall. The lower surface of the top plate above the container body opening 5 formed by the upper inner surface of the neck is defined as a first concave portion 6 having a lower surface opening, and the left and right portions of the top plate between the left and right inner wall surfaces of the first concave portion and the left and right surfaces of the outer periphery of the top plate. The upper surface of the top plate 4 is provided with a nozzle opening 7, and the upper surface of the upper surface of the top plate 4 is surrounded by a central upper surface as a second recess 10 having an upper surface opening, and an embedding plate 11 is fixed in the second recess. Liquid dispensing cap.

The cap has the advantage that the nozzle is hidden in the top plate and the external appearance can be improved as compared with the liquid ejection cap that projects the nozzle from the upper left and right portions of the cap peripheral wall. If the wall is made of synthetic resin due to its large thickness, dimensional errors are likely to occur due to generation of sink marks and the like. Therefore, the second concave portion is provided to reduce the thickness of the central portion of the top plate, and the embedding plates of different colors are fixed in the second concave portion to enhance the decorative effect of the cap.

[Problem to be Solved by the Invention] The liquid discharging cap, in which a nozzle hole is formed in the top plate so that the nozzle does not protrude outside the peripheral wall of the cap, the nozzle hole is formed in the top plate portion below the second recess. Therefore, the thickness of the outer surface portion 15 above the outer end of the nozzle hole between the upper edge of the outer end of the nozzle hole and the outer edge of the upper surface of the top plate above the upper edge becomes large. Then, as shown in FIG. 3, when the liquid inside the container body 1 is reduced, the liquid to be discharged flows out by touching the outer surface portion 15 when the liquid flows out while the bottom side is higher than the mouth of the container body. Therefore, even if the container body is returned to the upright state, the adhered liquid often remains on the outer surface portion 15 as it is, and then dust or the like adheres to the liquid, making it unsanitary, and the appearance is also dirty and unsightly. There were drawbacks.

In the present invention, the upper edge of the outer end of the nozzle hole is located above the bottom wall extension surface of the second recess formed in the upper surface of the top plate,
The thickness of the outer surface portion 15 above the outer end of the nozzle hole is reduced without impairing the overall shape of the cap, thereby preventing liquid from adhering to the outer peripheral portion of the top plate above the outer end of the nozzle hole, thereby preventing contamination of the portion. It was made possible.

[Means for Solving the Problems] A container in which a peripheral wall 3 to be screwed to a container body neck portion 2 is vertically suspended from the lower surface of a top plate 4 having a larger outer diameter than the peripheral wall, and an upper inner surface of the mouth neck portion is formed. The lower surface portion of the top plate above the body opening 5 is defined as a first concave portion 6 having a lower surface opening, and nozzle holes 7, 7 are provided in both left and right portions of the top plate between the left and right inner wall surfaces of the first concave portion and the left and right surfaces of the outer periphery of the top plate.
And a liquid injection cap made of synthetic resin, in which a central upper surface portion of the top plate surrounded by an outer surface portion of the upper surface of the top plate 4 is defined as a second concave portion 10 having an upper surface opening and an embedding plate 11 is fixed in the second concave portion. The outer end of the nozzle hole was widened upward such that the outer edge upper edge portion 17a of the nozzle hole 7, 7 was located above the extension surface of the bottom wall 10a of the second recess.

[Operation] The outer ends of the nozzle holes 7, 7 have been widened upward so that the upper edge 17a thereof is located above the extension surface of the bottom wall 10a of the second recess 10, so that the outer ends of the nozzle holes 7, 7 are located above the outer ends of the nozzle holes. The thickness of the outer surface portion 15 can be reduced, and as shown in FIG. 3, the liquid is poured out by lowering the mouth of the container body from the bottom portion thereof, and the portion 15 , And the attached liquid easily returns to the inside of the nozzle hole 7 via the outer end widening portion.

"Example" 1 is a container body for liquid storage, and a peripheral wall 3 of a cap of the present invention is screwed to a mouth and neck portion 2 thereof. The peripheral wall is vertically suspended from the lower surface of the top plate 4 having a larger outer diameter than the peripheral wall, and the lower surface of the top plate above the mouth 5 formed by the upper inner surface of the mouth and neck portion 2 is a first concave portion 6 having a lower surface opening. Nozzle holes 7, 7 are formed in both left and right portions between the inner peripheral wall surface of the first recess and the outer peripheral surface of the top plate. The nozzle hole 7 is an inclined hole that rises slightly from the inside to the outside, and a groove 7a is formed in the bottom side along the hole direction. Numeral 8 denotes a packing 9 fitting recess, which is provided on the lower surface of the top plate portion between the lower end of the first recess and the inner surface of the upper end of the peripheral wall 3.

The upper surface of the upper surface of the top plate 4 is surrounded by a second recess 10 at the center upper surface of the top plate which is surrounded by the outer peripheral portion.
Is fitted.

The above is the same as the conventional example. In the invention of the present application, the outer ends of the nozzle holes 7, 7 described above have their upper edges 17 a formed on the bottom wall 10 of the second recess 10.
The width was widened upward so as to be located above the extension surface of a. To do this, as FIGS. 4A and 4B show,
In the upper surface of the outer side of the nozzle hole 7, a lower surface opening groove 12 which rises outward from the inner side of the nozzle hole may be formed.
As shown in FIG. 6, the upper half of the outer side of the nozzle hole may be provided so as to be enlarged 13 so that the outer side expands, and further, as shown in FIGS. 6A and 6B, on the outer surface portion of the outer end of the nozzle hole. A semicircular third concave portion 14 may be formed in a half.

"Effects of the Invention" The present invention has the configuration described above, and a peripheral wall originally screwed to the neck portion of the container body is vertically suspended from a top plate having a larger outer diameter than the peripheral wall, and the top plate above the mouth portion of the container body. The lower surface portion is a first concave portion,
A liquid pouring cap in which nozzle holes are drilled in both left and right portions of the top plate between the left and right inner wall surfaces and the left and right surfaces of the top plate outer periphery, and the top plate upper surface center portion is a second recess and the embedding plate is fixed in the recess. However, the thickness of the outer peripheral portion 15 above the outer end of the nozzle hole becomes large, so that when the container body is tilted and tilted greatly and the liquid is poured out, the liquid easily adheres to the outer surface portion 15, and therefore, the liquid adheres to the outer surface portion 15. There was a disadvantage that the outer peripheral portion of the outer end of the nozzle hole was easily contaminated due to dust adhesion or the like, but in the present invention, the outer end of the nozzle hole is positioned such that the outer edge upper edge 17a is higher than the extension surface of the second concave bottom wall 10a. As it is located so as to be located upward, the thickness of the outer surface portion 15 above the outer end of the nozzle hole can be reduced, and liquid adhesion to the portion can be reduced, and the adhering liquid can be spread through the outer end widening portion. Prevent dirt on the outer peripheral surface of the nozzle hole because it easily returns to the inside of the nozzle hole Can.
