JPS5916136Y2 - Synthetic resin handle for small manual sprayer - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a synthetic resin handle for a small manual sprayer.

Conventionally, small hand-operated sprayers have been provided with a handle for pushing down the spray head.

Generally, the handle has its base end pivoted to a support tube, etc., and the operating part on which the finger is placed protrudes outward from the support tube, etc., which makes it difficult to package or wrap. It was going to get bigger.

Furthermore, since the handle consists of a support tube and a printing part, complicated assembly work is essential, as it involves pivoting work.

Therefore, in the present invention, the handle is made of synthetic resin and is integrally molded with the holding cylinder and the hinge, and the approximately intermediate part between the pressing part and the operating part is formed into a hinge so that the operating part can only be folded upwards. The synthetic resin handle can be easily molded together with a holding cylinder in one step, and can be folded up when not in use, especially when being packed, for convenient and compact packaging.

The drawings showing the embodiments of the present invention will be explained below.
In FIG. 3, reference numeral 1 denotes a pressurized chamber configured by fitting a piston (not shown) into a cylinder 2 equipped with a check valve in the lower passage hole, and a nozzle hole 4 of a spray head 3 connected to a slider. By pushing down the spray head against the elastic force of the spring that pushes the spray head 3 upward, the suction liquid in the pressurized chamber is released from the nozzle hole into the sprayer, and when the above-mentioned depression is released, the spring is released. Container 6 is returned by pushing up the piston due to elastic force.
This is a spraying means that sucks the liquid inside into a pressurized chamber and prepares for the next spray.

Reference numeral 7 denotes a holding cylinder for supporting the spraying means, which is screwed into the container mouth neck 6a to hold the spraying means vertically within the container, and the front and rear walls 8 of the holding cylinder extend upwardly to form a valley in the middle. Protection part 10.10 of the spray nozzle formed in part 9
is formed on the same plane as the top wall of the spray nozzle, and the trough 9 has a space between which the spray nozzle 3 can be moved up and down, and where a handle, which will be described later, can be inserted between the front and rear protection parts 10 and 10. It is held and received through a through hole 12 formed in the bottom wall 11 thereof.

This holding cylinder 7 is integrally molded from thermoplastic synthetic resin.

Reference numeral 13 denotes a handle, which is curved as shown in the figure with a width that can be received in the valley part 9, and has a horizontally long window hole 14 into which the spray head 3 can be inserted, and its front and rear edges 15 and 15 are curved as shown in the figure. A pressing part 17 that engages the engaging protrusions 16, 16 protruding at the front and rear of the spray head in the pushing down direction, and a front end of the pressing part and a thin hinge 18 integrally move the operating part 19 forward. Protruding,
Further, the hinge 18 is formed so that the operating portion 19 can be bent only upwardly, overlapped and folded onto the upper surface of the pressing portion 17, and not bent downwardly.
The base end of the suppressing portion 17 is continuous with one side wall of the holding tube 7 through a thin hinge 20, and is integrally molded with the holding tube from a thermoplastic synthetic resin material.

Further, the holding cylinder 7 and the handle 13 may be integrally molded by injection molding with the handle expanded upward or backward from the hinge 20.

Therefore, in the above configuration, when not in use, especially when packing, the first
As shown in the figure, the operating part 19 can be bent upward from the hinge 18 to overlap the upper surface of the pressing part 17 and folded, and in this state, if the pressing part is made parallel to the upper surface of the protective part 10.10,
The operation part 19 closes the window hole 14 of the pressing part and closes the spray head 3.
As a result, the handle is folded compactly to the same width as the diameter of the holding cylinder so that it does not protrude outward, and the spray head is also protected from the outer cylinder. It is.

In addition, when in use, as shown in FIGS. 2 and 3 from the hinges 18 and 20, the pressing part 17 is slightly tilted forward to engage the engagement protrusion 16, and the operating part is further extended forward. The handle 13 is tilted forward so that it is easy to put the finger of the hand holding the container on it, and if you pull the operating part in this state, the engaging protrusion 16 will engage and the spray head 3 can be pushed down, allowing the liquid to flow out. Spraying operation becomes possible.

Furthermore, since the pressing portion 17 of the handle is curved with an appropriate curvature as shown in the figure, the curved surface slides on the engaging protrusion 16 while pivoting about the hinge 20 and presses the spray head. Therefore, the spray head is pushed down in the vertical direction and does not tilt.

As described above, since the resin handle of the present invention is constructed, it is necessary to lean forward when spraying liquid, and although it protrudes long and makes spraying operations easier, the handle is located almost in the middle. Since the operating part 19 can be bent from the hinge 13 and folded onto the upper surface of the pressing part 17, and does not protrude outward from the outer wall surface of the holding cylinder 7 for a long time, it is easy to pack it and can be packed compactly. Also, this allows the handle to be protected from the outer cylinder during transportation, thereby preventing breakage or the like.

Further, since the operation part 19 closes the window hole 14 of the pressing part 17 and folds to cover the spray head 3, the spray head can also be protected from the outer cylinder.

In addition, since the handle is integrally molded with the holding tube 7 from synthetic resin, it can be easily molded together with the holding tube in one step, and the process of assembling the handle can also be omitted, improving productivity and making it cheaper to manufacture. It has a number of excellent effects, such as the ability to do things you want to do.
