Description

[Detailed explanation of the idea] This case concerns a liquid dispenser.

Recently, biaxially stretched bottles have come into widespread use for reasons such as improving strength and gas barrier properties, and reducing weight by making them thinner, but with conventional shapes,
In particular, since the biaxial stretching of the bottom wall of the bottle is insufficient, the bottom wall is formed into a convex spherical shape that bulges downward.

This project relates to a liquid dispenser using a biaxially stretched bottle as described above, which can be transported with the biaxially stretched bottle attached, and can dispense liquid as is by changing the cap. It was made possible to do so.

Describing the drawings below, reference numeral 1 indicates the main member. The main member has a peripheral wall 2 whose upper surface is closed by an upper wall 3 whose lower surface is a concave spherical surface. The lower surface of the peripheral wall is open, and a lower part of the peripheral wall is cut out to form a tip insertion opening 4. The peripheral wall is formed into a rectangular plane, and the insertion opening is cut out across the entire lower part of the peripheral wall plate forming one side of the rectangle and a part of the peripheral wall plate adjacent to that side. Laterally elongated through holes 5, 5 are bored in the lower part of the partially cut out peripheral wall plate, and the portions of the peripheral wall plate below the through holes are formed into handles 6, 6. In addition, there are fitting holes 7 on both the left and right sides of the peripheral wall plate immediately above the horizontally long through holes.
... are bored, and the fitting holes are also bored in the peripheral wall plate portion where the above-mentioned notch is not provided, and in the peripheral wall plate portion where the entire lower part is notched.

A support member 8 is fitted into the main member. The support member has a horizontal wall 9 that divides the inside of the main member into upper and lower parts. The horizontal wall has an upper surface formed into a concave spherical surface, and has a through hole 10 in its center. Side wall 9
is a second peripheral wall 11 fitted into the peripheral wall 2 of the main member.
It is preferable to provide a protrusion 1 to be attached to the upper surface of the second peripheral wall, and a protrusion 1 to be fitted into the aforementioned fitting hole on the outer surface of the second peripheral wall.
2... is attached.

A biaxially stretched bottle 13 is placed between the side wall 9 and the top wall 3 mentioned above.
Insert the body part 14 of. The bottle has a bottom portion 14a and a shoulder portion 14b formed into convex spherical surfaces, and a neck portion 15 that is inverted and protrudes from the shoulder portion 14b.
It is made to protrude downward from a through hole 10 bored in the center of the aforementioned side wall. The bottom portion and the shoulder portion are provided to match the concave spherical surfaces of the top wall 3 and the side wall 9, and the shoulder portion is supported by the top surface of the side wall. An outward flange 16 is attached to the base of the mouth and neck, and a cap 17 is fitted to the mouth and neck.

A top wall 18 of the cap 17 is provided with means 19 for pouring out the liquid in the bottle and means 20 for introducing outside air into the bottle. The liquid spouting means includes a spouting tube 21 vertically disposed from the periphery of a liquid spouting hole bored in the top wall, a spouting pipe 22 fitted into the spouting tube, and a spouting stopper attached to the tip of the spouting pipe. 23 are fitted, and when the push button 24 is pressed, the spout valve 25 opens to enable pouring. The spout is fixed to the peripheral wall above the spout. 26 is a tip. Outside air supply means 20
is formed by fitting an outside air inlet pipe 28 with its upper end close to the bottom wall of the bottle into a fitting tube 27 that stands up inside the bottle from the periphery of an outside air inlet hole bored in the top wall 18. There is. The cap is detachable from the neck of the bottle, and can be used in place of the cap 29 for transportation when used as a liquid dispenser.

When the push button 24 is pressed in the state shown in FIG. 1, the pouring valve 25 opens and the liquid in the bottle is poured out, and at the same time, outside air flows into the bottle through the outside air inlet pipe 28 to replace the poured liquid. do.

The above-mentioned liquid dispenser shall be placed in a state in which the tip insertion port is located at the bottom only when dispensing liquid, and in a state in which the insertion port is located at the top during transportation, etc., as shown in FIG. 4. In this case, the mouth of the bottle may be sealed with an ordinary cap 29 having no liquid pouring means or the like.

The present invention has the above-mentioned configuration, and since the bottle used in the liquid dispenser is a biaxially stretched bottle, it is lightweight and has excellent gas barrier properties and strength. The lower surface of the upper wall of the main member and the upper surface of the side wall of the supporting member are formed into a concave spherical surface that matches the bottom and shoulder of the bottle. Since they are pressed together, the biaxially stretched bottle will not wobble, and since the body of the biaxially stretched bottle is housed within the space formed by the main member and the support member, other objects will not come into direct contact with the bottle wall. Therefore, there is no problem even if the bottle wall is made extremely thin, since the cap is equipped with a liquid pouring means and an outside air feeding means, and a bottom part of the peripheral wall of the main member is cut out to provide a cap insertion opening. , liquid can be easily dispensed.
