JPS5815313Y2 - Container with cap for liquid dispensing - Google Patents

Description

[Detailed explanation of the idea] This proposal relates to a container with a cap for dispensing liquid.

Conventional liquid pouring caps have usually been fitted to the neck of a container dedicated to liquid pouring, but not to the container body for transporting liquids.

This is because the cap has a liquid spout hole and is therefore unsuitable for sealing the mouth of the container body.

The present invention can be used to seal the container during liquid transportation, and can also be used for pouring out liquid.The first embodiment shown in FIGS. 1 to 3 will be explained below. It is a storage container body, and a cap screw 2 is attached to the outer surface of the neck part 1a.

A peripheral wall of an inner stopper 7 is fitted in a watertight manner into the neck of the container, and an outward flange 1 attached to the upper end of the peripheral wall.
1 is engaged with the top surface of the container.

An inward flange 8 is provided around the inner periphery of the lower end of the inner plug circumferential wall, and the inward flange is provided with notches 16 at approximately equal intervals, with the non-cut portions being cut out. is the engaging protrusion 9
It forms...

In other words, the lower end surface of the inner plug peripheral wall is the flange hole 1 of the inward flange.
It opens at the 0 part and the notch 16 part.

The inner diameter of the upper part of the circumferential wall of the inner plug is a small inner diameter part, and a suitable number of vertical grooves 15 are vertically provided in the small inner diameter part.

Further, the inner circumferential portion of the upper surface of the outward flange is formed lower than the outer circumferential portion 11a.

The inner circumferential edge of the inner circumferential portion and the upper end edge of the vertical groove are continuous at an arcuate surface 14.

A sealing plug 20 having a peripheral wall erected from the peripheral edge of the bottom wall is fitted into the peripheral wall of the inner plug in a watertight manner.

The sealing stopper circumferential wall has an outer diameter larger than the upper inner diameter of the inner stopper circumferential wall, and is removably attached to the lower half of the inner stopper circumferential wall by elastically deforming the sealing stopper.

The bottom of the sealing peripheral frame is supported by the aforementioned engaging protrusions 9 to prevent the plug from being pulled out downward, and the upper end of the peripheral wall is in contact with the small inner diameter part of the inner plug peripheral wall soil. Upward withdrawal of the stopper is prevented.

An elastically deformable knob 21 projects from a portion of the upper end of the circumferential wall of the plug toward the center of the circumferential wall.

The cap 3 is fitted by pressing the inner surface of the peripheral edge of the top wall against the upper surface of the outward flange of the inner stopper described above, and by screwing the peripheral wall hanging down from the peripheral edge of the top wall into the neck of the container body.

The cap has a recess 4 with a bottom opening formed on the inner surface of the central part of the top wall, and a through hole 17, 17 for dispensing liquid and inhaling outside air from the upper end of the recess to the outer peripheral surface of the top wall. be.

The inner diameter of the recess is the same as the inner diameter of the mouth and neck of the container body, and the remaining inner surface of the top wall between the recess and the inner surface of the peripheral wall forms a downward step 5, and the inner circumference of the downward step 5 is located above the inner peripheral part of the upper surface of the outward flange 11, and forms an annular groove 13 between it and the inner peripheral part.

Further, grooves 18 and 19 are bored in the bottom surface of the through hole 17 and 17 and in the concave forming wall surface below the inner end of the through hole. A groove communicating with the groove 13 is formed.

The annular groove 13 can also be formed as in the second embodiment shown in FIGS. 4 and 5.

That is, in the second embodiment, the annular protrusion 11a projects upward from the inner circumferential edge of the upper end of the peripheral wall of the inner plug 7, and the annular groove 13 is formed between the outer surface of the annular protrusion and the lower part of the recess forming wall. is formed.

The lower outer surface of the annular projection is formed into a curved surface 22.

The upper surface of the outward flange 11 is formed horizontally, and the vertical groove 15 is formed horizontally.
The upper annular protrusion portion is a notch.

In the second embodiment, the knob 21 of the sealing stopper is erected upward.

The present invention has the above-mentioned structure, and after filling the container with liquid, each member is fitted as described above and transported, etc., and the consumer uses the sealing stopper 20 with the cap removed.
The device is forcibly pulled upwards to remove it, then capped again to dispense liquid.

The present invention has the above-mentioned structure, and the sealing stopper 20 is fitted into the inner stopper fitted into the neck of the container, and the cap for pouring liquid is fitted onto the outer surface of the neck of the container. There is no leakage even if the cap is transported while the cap is fitted, and the sealing stopper has an engaging protrusion 9 whose bottom protrudes from the inner surface of the lower end of the circumferential wall of the inner stopper. Since the upper part of the inner stopper circumferential wall has a smaller diameter than the outer diameter of the sealing stopper circumferential wall, the sealing stopper will not come off in both the vertical direction and the sealing stopper can be elastically deformed. Even though the outer diameter of the outer circumferential wall of the inner plug is larger than the inner diameter of the inner diameter of the surrounding wall of the inner plug, its elastic deformation allows it to be attached to and removed from the lower part of the surrounding wall of the inner plug, and the engaging protrusion acts as a flow rate control piece when liquid flows out. Also, an annular groove 13 is formed between the outward flange of the inner plug and the inner surface of the outer circumference of the top wall of the cap above the outward flange.
At the same time, grooves 18 and 19 communicating with the annular groove 13 from the outer edge of the through hole are bored in the bottom wall portions of the through holes 17, 17 and the wall surface forming the recess, and Since the vertical groove 15 is formed in the small inner diameter portion 23 of the container, when the container body is returned to the upright position after pouring out the liquid, the liquid adhering to the through hole serving as the spouting hole passes through the groove 18 and 19. The suction force causes the liquid to be pulled back into the annular groove 13 and returned to the container body through the vertical grooves 15, so that the liquid adhering to the inner surface of the hole remains dry. There is no white basis.
