A pouring adapter insert for bottles containing liquid products, allowing quick delivery of the desired quantity of liquid without spurting or glugging.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a new and improved insertable dispensing device for use in a container for liquid products, and more particularly to The present invention relates to a dispenser that makes it possible to perform controlled dispensing for containers with a vertical outlet neck, without causing blowouts or blockages.

[Prior art and problems]

Containers for dispensing and retrieving liquids are often equipped with a spout placed within the neck of the container to control the flow rate of the liquid and prevent "spills and drips" of the liquid contents. Such a spout is usually placed over the neck end of the container and provides a means for the outflow of liquid and the inflow of air, and is often a ring-shaped spout. Turn right at Yoyabe.

U.S. 14th edition 3,980,211 specification-1 is? We accept orders for a vent and lid (to control the flow of water and prevent gushing and blockage). However, with this structure of Φ, it is difficult to control the flow W to be fully 1 for a liquid whose viscosity is within the range iIu.

US ILJ Special S'r3. ', 693.8/I 75 S Specification iJ: indicates a dark blue combination of the bi/υ key I7 knob and the spout, which is placed on the inside of the neck of the bi/υ. Even with this, the ejector may not work equally well for liquids of different viscosities.

Additionally, all current insertable dispensers dispense the desired amount of liquid (in a sufficiently short period of time without gushing or clogging) when the liquid reaches a certain viscosity. This dispensing of the desired amount of liquid within 11.1 minutes is desirable, for example, for constant dispensing of liquid cleaning agents or softeners.

[Objectives and Effects of the Invention] The object of the present invention is to provide a container for liquid products having a wide range of viscosities, which controls the flow rate of the liquid and prevents the gushing from clogging. i: Provides an insertable dispensing device.

Another object of the present invention is to produce a desired amount of fluid, squirt or blockage! 'f, within a limited plane), it is possible to make one output J.

Other objects and advantages of the present invention are as follows.

If the liquid flow is appropriately controlled to avoid spouting or blockage, at 1111, in order to pour out the desired amount of liquid within a certain time, it is necessary to provide means for liquid outflow J3 and air inflow. It has been discovered that simply taking the necessary steps is not enough. More specifically, what is extremely important is that the air
The air m is the amount of liquid to be poured out, J3, and the speed at which the desired amount of liquid is poured out is J. It is influenced by the viscosity of the liquid product being used.

[Summary of the invention]

Fruit according to the present invention! The insert and outlet for liquid product containers having a generally vertical outlet neck are generally cup-shaped and have an open upper end and a closed lower end.

The dispenser further includes a peripheral wall connecting the open upper end and the closed lower end, and one or more vertical slots (elongated holes) are formed in the peripheral wall, and the peripheral wall has the following features: Closely adheres to the inner surface of the vertical exit neck. The top of each strike 1- is placed close to the inner surface of the neck 1'', and the remainder of the slot
, extending downward into the body of the container.

The dispenser may further include other means known in the art, such as a drip-free dispensing trough;
A disc-shaped bottom wall is installed to control the wave motion of the product (liquid).

[Embodiments of the invention]

Hereinafter, an embodiment of Mizumoto (11) is shown in the drawings and will be explained.

As shown in Figure J3, the insertable dispenser 1 according to the invention is designed to be easily inserted into the container neck, and then placed stably therein to cover the sea urchin. , preferably made from a resilient flexible material.

As shown in FIG. The open chain lower end 6 is conical in the illustrated embodiment J3, but may have other shapes, e.g.
A disk shape (i.e., a planar shape) is also used in the same way. At the top of the dispenser, there is a ring-shaped dispensing lip that prevents dripping to minimize the amount of spillage during dispensing operations. This pouring trough 8
Slightly below is provided an annular horizontal flange 7 for placing the spout on the upper end of the container neck 2. The diameter of the spout is such that the vertical part 3 of the circumferential wall frictionally engages the inner surface of the container neck. One or more slots 5 are made in the tapered portion 4 of the peripheral wall.

FIG. 3 shows a spout 31 in close contact with the inner surface of the vertical neck 2 of the container, with the flange 7 resting on the upper end 9 of the neck 2.

In order for the air to be properly guided into the container so that the liquid can be dispensed without spouts or blockages,
It has been found that it is desirable that the upper one-third of the slot 5 be placed near the bottom of the vertical neck 2 and the lower two-thirds of the slot 5 be in the body 10 of the container. The part of the vertical throats 1 to 5 near the neck of the container can be varied depending on the viscosity of the product to be dispensed, but to ensure a smooth inflow of air into the container during sweating, it is necessary to y5 that at least the top of 1-5 is placed near the vertical neck.
It has been discovered that the viscosity of the N product is 50 to 100.
cps range, the upper 1/2 of throwers 1 to 5
3 is placed near the bottom of the container neck, and the remaining two-thirds of the slot 5 extends from the neck to +h into the container body.

At this time, the incoming air is inside the spout 1)'1)
Then, it is guided from the upper part of the throwers 1 to 5 to the inner surface of the neck 2', and from there to the inner surface of the container body. This smooth guidance of the air inflow ensures even ventilation and thus makes it possible to dispense the product evenly without blockages or squirts. The method and number of L1-5 to be made are determined by the amount of liquid to be dispensed, viscosity, A3J, and desired dispensing speed. It has been found that if the number of slots 5 is at least 51, then b.) the problem of the position of the knife for inserting the ejector into the neck of the container is not the same if the container is non-cylindrical.

Testing of the dispenser described above was conducted for dispensing liquids having viscosities in the range of approximately 50-100 cps.

Desired item number, within 2 seconds, pour 37 cc of liquid into f without any "squirt or 1" blockage and using a measuring device.
That was the case. Number 1: This is absolutely impossible without using a pourer. This is because if there is no control means, the flow will depend on the user.

U.S. Pat. No. 3.693.847 or 3.98, cited above.
0,211, the =J method is adapted to the viscosity of the liquid to be dispensed, and the desired level is adjusted to It takes more than 2 seconds to pour out, and if you try to pour it out as quickly as possible,
+ A blockage occurred. Tests using transparent container necks have clearly shown that occlusion occurs due to the encounter between incoming air and exiting liquid.

Similar tests were then conducted on the d-small device of the present invention. An oval bottle with a vertical cylindrical neck of 15 mm in height is filled with water and a spout is inserted into the circumferential wall, which has a height of 30 am below the annular flange 7. It is placed on the upper end of the 531 part and frictionally engaged in the neck, and the earth part 3 of the said peripheral wall is 10 mm in length and has a vertical shape. The tapered lower part 4 of the peripheral wall is at an angle of approximately 5° to the inner surface of the vertical neck of the container;
What are the five slots 1 to 5, and each slot (~ is 20mm
The vertical length and width of the pipe are 2.5 mm, and the inner diameter of the spout is 18 m at the open upper end and 15 mm at the lower end.

It was found that 37 cc of fluid was expelled in 1.7 seconds without any spurt or blockage.

Although the lower part 4 of the circumferential wall of a similar dispenser was made vertical without a 7-bar, the fact is that it was an extension of part 3, and the test was repeated with the same strip A'1. . The lower part of the peripheral wall similarly has five throwers 1-1, and the upper part of each thrower 1-
/3 was placed near the top of the vertical neck of the container. Even in this case, 37 cc of fluid was sweated out in 1.7 seconds without any gushing or blockage.

Variations in the shape and shape of the throat 1~ of the retaining means are possible within the scope of the present invention, and also include the outside of the bottle (container) neck, the spout positioning and retaining means J3, and the dispensing lip. The shape of the part is bilυ! It can be changed by the observation of the rose that is planted in the temple.
