A push type cock according to the present invention will be explained with reference to the drawings. Note that the present invention is not limited to the contents described in the embodiments below, and includes other embodiments and usage examples that can be considered within the scope of the matters described in the claims. Further, various changes and combinations of the above embodiments may be made without departing from the gist of the present invention.

[Push type cock]
As shown in FIGS. 1 to 4, the push cock 10 according to the present invention includes an attachment part 1 for attaching to the mouth of a container, a spouting part 2 for dispensing liquid contained in the container, and an attachment part 1 for dispensing the liquid contained in the container. It has at least a liquid guide part 3 that connects the part 1 and the pouring part 2. The spouting part 2 includes a push button 21 provided at the top, a spout 22 provided at the bottom, and a rear side A of the spouting part 2 provided between the push button 21 and the spout 22. and a protrusion 23 extending toward the front side B.

This push-type cock 10 has a protruding part 23 on the spouting part 2 that extends in the front-rear direction Y on the back side A and the front side B between the push button 21 and the spout 22, so that it can be moved forward and backward. The lower surfaces 24a, 24b of the extending protrusions 23 (23a, 23b) are supported with the index and middle fingers, and the push button 21 can be pressed with the thumb. Since the protruding parts 23 are provided on the front and back, it can be operated without bending the wrist, reducing the burden on the wrist when pouring, and even when the spouting part 2 is above the shoulder, the button can be pressed. It's easy to put pressure on your fingers when pushing down. As a result, the dispensing operation can be easily performed regardless of the position of the dispensing part 2 (below the shoulder, at the same position as the shoulder, above the shoulder).

Each configuration will be explained below. Although the opening to which the push-type cock is attached and the container equipped with the opening are not shown, examples of the container include a plastic tank, a bag-in-box, and the like. In the case of a bag-in-box, an example is one that is usually fixed to an outer box (not shown) that houses the bag, and all of these are well known. In FIG. 1, symbol X is the left-right direction, symbol Y is the front-back direction, and symbol Z is the vertical direction.

The attachment part 1 is a part for attaching to the mouth of a container, as shown in FIG. 1 and the like. The shape of the attachment part 1 is not particularly limited as long as it can be attached to the mouth of the container. The attachment part 1 usually has a female screw structure so that it can be screwed into a mouth formed on a male screw, but the opposite may be used.

The liquid guide part 3 is a part that connects the attachment part 1 and the spouting part 2, and has a through hole (not shown) through which the liquid in the container can be guided to the spouting part 2.

The pouring section 2 is a portion that pours out the liquid contained in the container. In the present invention, the spouting part 2 is provided with a push button 21 provided at the top, a spout 22 provided at the bottom, and between the push button 21 and the spout 22. It is characterized by having a protrusion 23 extending to the back side A and the front side B.

The push button 21 is a part that is provided at the upper part of the spouting part 2 and acts to open and close the spout 22 when pressed. The distance L2 from the top 21a of the push button 21 to the lower surfaces 24a, 24b of the protrusion 23 is not particularly limited, but is preferably within a range of 10 to 50 mm. By doing this, the distance L2 operated by the reaction force of the fingers is within the above range, so it is easier to apply grip force and the operation can be performed more easily than when the distance is shorter than that. In particular, regardless of the position of the spouting part 2 (below the shoulder, at the same position as the shoulder, above the shoulder), grip force can be easily applied even when operating from above the shoulder.

The spout 22 is the tip of the spout 2 that spouts out the liquid contained in the container. The liquid poured out from the spout 22 is normally supplied to an optionally attached measuring cup or the like.

As shown in FIGS. 1 to 4, the protrusion 23 is provided between the push button 21 and the spout 22 and extends to the back side A and the front side B of the spout 2. It is preferable that the portion 23a extending toward the back side and the portion 23b extending toward the front side of the protruding portion 23 have a length L1 that allows a finger to be placed over the projection portion 23 from below. Such length L1 is preferably within a range of about 10 to 20 mm. By doing this, you can put your index finger on the part 23a extending toward the back, your middle finger on the part 23b extending toward the front, and then put your thumb on the push button 21, and push the push button 21 with the reaction force. Liquid can be easily poured out from the spout 22.

The lower surfaces 24a and 24b of the protrusion 23 are preferably flat, or curved or substantially curved along the finger shape. As can be seen from the side views of FIGS. 2 and 3, for example, by making the tip of the portion 23b extending toward the front slightly thicker downward, the lower surface 24b on the tip side can be made into a gently curved shape. By doing so, it is easy to put fingers on the lower surfaces 24a and 24b of the protrusion 23. Note that, of course, it may be a flat surface.

The example in FIG. 3 shows a case where the position of the portion 23b extending toward the front side of the protrusion portion 23 is provided below the position of the portion 23a extending toward the rear side in the vertical direction Z. By doing this, it is easy to put the index finger on the part 23a extending toward the back, the middle finger is easy to put on the part 23b extending toward the front, and it is easy to put the thumb on the push button 21 and press it. The difference L3 between the position of the lower surface 24a of the portion 23a extending toward the back and the lower surface 24b of the portion 23b extending toward the front is not particularly limited, but may be within a range of 5 to 30 mm, for example.

In the example of FIG. 3, the portion 23a extending toward the back of the protrusion 23 also serves as the liquid guiding portion 3, but such a structure may be used.

As explained above, in the present invention, since the protruding parts 23 are provided at the front and rear, it is possible to operate without bending the wrist, there is less burden on the wrist when dispensing, and the dispensing is performed above the shoulder. Even if part 2 is present, force is likely to be applied to the fingers when pushing the button down. As a result, the dispensing operation can be easily performed regardless of the position of the dispensing part 2 (below the shoulder, at the same position as the shoulder, above the shoulder).
