Description

  The present invention relates to a squeeze coating container for coating various coating liquids such as a water repellent, an antifogging agent, and a cleaning agent on the body of a car, a window glass, and the like.

  Conventionally, if the car body, window glass, etc. become dirty due to signs of rain on the car body, window glass, etc., or dirt, etc., the driver, etc., has applied a coating container containing a cleaning agent, etc. A cleaning agent or the like is applied to the vehicle body, window glass, etc. by using a wiping cloth to wipe off traces of rain, dust, etc. adhering to the vehicle body, window glass, etc., with a wet cloth. In addition, for drivers who prefer to keep the appearance of the car clean and clean at all times, periodically apply the cleaning agent etc. to the main body of the car or window glass with a coating container and adhere to the car body etc. It is done to wipe off the dust and the like with a wet cloth.

  As such an application container, for example, a squeeze application container as shown in FIG. 7 is used. In this squeeze-type application container, when used, the body part 31a of the container body 31 is strongly grasped with fingers, and the application liquid 30 in the body part 31a is discharged upward from the nozzle 34 of the lid body 32 (see the arrow in FIG. 7). The container body 31 in which the mouth and neck part 31b stands from the upper surface opening of the body part 31a that can be elastically squeezed, and the lid body 32 that is screwed to the mouth and neck part 31b of the container body 31 And a pipe 33 disposed in the body portion 31a. In addition, a through hole 32a is formed in the center of the lid 32, and a nozzle 34 projects from the upper surface of the lid 32 so as to surround the through hole 32a. The upper end portion of the pipe 33 is inserted through the through hole 32a, and the lower end portion is positioned at the bottom portion of the trunk portion 31a.

  In use, the body 31a is strongly gripped with fingers with the nozzle 34 facing upward or sideward (slightly upward), thereby increasing the internal pressure of the body 31a and applying the coating liquid 30 in the body 31a. After flowing into the pipe 33 from the liquid inlet (lower end opening) to raise the pipe 33 and the nozzle 34, the liquid is discharged from the tip opening of the nozzle 34. On the other hand, when the finger is released from the body part 31a after discharge, outside air flows into the body part 31a through the pipe 33, and the body part 31a returns to its original shape by its own restoring force.

  In addition, when applying the coating liquid 30 to a car body or the like of an automobile, there are times when it is desired not only to spray the coating liquid 30 vigorously upward and laterally but also to drop it downward. However, in the above-described squeeze-type coating container, the container body 31 is turned upside down (the nozzle 34 is directed downward) after the coating liquid 30 in the body portion 31a is reduced after a little use (or from the beginning of use). ), The liquid inlet of the pipe 33 is positioned higher than the liquid surface of the coating liquid 30, and the coating liquid 30 is allowed to flow from the liquid inlet of the pipe 33 and drop downward from the tip opening of the nozzle 34. Can not.

  Accordingly, a container with a liquid storage chamber as shown in FIG. 8 has been proposed. The container includes a container body 35 (same structure as the container body 31), a mounting cylinder 36 screwed to the mouth-and-neck part 35b of the container body 35, and the mouth-and-neck part of the container body 35 by the mounting cylinder 36. A liquid outflow cylinder 37 placed and fixed on the upper end surface of 35b, a pressing head 38 fixed to the upper end of the liquid outflow cylinder 37, and a liquid reservoir chamber with a lid plate 39a formed in the pressing head 38 39. And the upper end part of the pipe 40 arrange | positioned in the said trunk | drum 35a is penetrated by the said liquid outflow cylinder 37, and the lower end part is positioned by the bottom part of the said trunk | drum 35a.

During use, the body 35a is firmly held with fingers, and the liquid (not shown) in the body 35a is stored in the liquid storage chamber 39 via the pipe 40, the liquid outlet cylinder 37, and the spout 38a of the pressing head 38, After the reservoir, the lid plate 39a is opened and the container body 31 is directed downward so that the liquid stored in the reservoir chamber 39 is dropped downward (for example, see Patent Document 1).
JP 2005-162225 A

  However, in the container with a liquid storage chamber, since the liquid storage chamber 39 is provided above the container body 35, the height of the container with the liquid storage chamber is increased and the size is increased. Moreover, since the liquid reservoir chamber 39 is located outside the container body 35, a lid plate 39a for covering the upper surface opening of the liquid reservoir chamber 39 must be provided, which increases the manufacturing cost and complicates the structure. . In addition, since the liquid in the container body 35 is stored in the liquid storage chamber 39, the liquid cannot be directly discharged upward from the pipe 40.

  The present invention has been made in view of such circumstances, and is small in size, low in manufacturing cost, simple in structure, and directly discharges liquid or drops it downward. An object of the present invention is to provide a squeeze-type coating container.

  In order to achieve the above object, a squeeze coating container according to the present invention includes a bottomed cylindrical container body having squeeze characteristics, and a lid that covers the opening of the container body. Providing an outlet for the coating liquid to be accommodated in the container body, providing a coating liquid storage chamber in communication with the outlet in the upper space in the container body, and providing a through-hole in the bottom wall of the coating liquid storage chamber; A pipe body having an upper end opened to the coating liquid storage chamber and a lower end opened to the lower space in the container body is inserted into the through hole in a liquid-tight manner, and the upper end of the pipe body is connected to the outlet. In the tilted state of the container body, the coating liquid stored in the coating liquid storage chamber is passed through the gap between the upper end of the tubular body and the outlet and is discharged from the outlet. It is configured so that it can be dropped.

  That is, the squeeze coating container of the present invention is provided with a coating liquid storage chamber in the upper space in the container body having squeezing properties (which can be elastically squeezed), and in the through hole provided in the bottom wall of the coating liquid storage chamber, A tube body whose upper end opens into the coating liquid storage chamber and whose lower end opens into the lower space in the container body is inserted in a liquid-tight manner. Further, the upper end of the tube body is positioned at a position where a predetermined gap is formed between the upper end of the tube body (which covers the opening of the container body) and the outlet of the lid body. Therefore, in the squeezed state (the state in which the container body is strongly gripped with fingers), the pressure in the container body increases, and the coating liquid in the container body flows in from the lower end opening of the tube body, rises inside, and flows out from the upper end opening. Although most of the outflowing coating liquid is fed into the outlet of the lid and discharged from the outlet (or from the liquid passage after passing through the liquid passage extending from the outlet), a part of the coating liquid is It jumps out from the gap to the surroundings and accumulates in the coating liquid storage chamber. When the coating liquid stored in the coating liquid storage chamber is tilted downward, the coating liquid flows out from the coating liquid storage chamber, flows into the outlet through the gap, and then from the outlet (or from the outlet). After passing through the extending liquid passage, it is dropped downward (from this liquid passage).

  As described above, in the squeeze coating container of the present invention, since the coating liquid storage chamber is provided in the upper space in the container body, the space in the container body can be used effectively, and the entire container is enlarged. do not do. Moreover, since the coating liquid storage chamber is provided in the upper space in the container main body, the lid that covers the opening of the container main body can also be used as the lid of the coating liquid storage chamber, and the manufacturing cost is low. In addition, the structure becomes simple. And in a squeeze state, the coating liquid in the lower space of a container main body can be discharged from an outflow port via the said pipe body.

  Further, the axial center of the upper end opening of the tube body is positioned at a position shifted laterally with respect to the axial center of the outlet port of the lid body, so that the outlet port is positioned above the upper end opening of the tube body. A part of the coating liquid that has flowed out from the upper end opening of the pipe body in the squeezed state is collided with a part of the outlet and scattered around, and this is received and stored in the coating liquid storage chamber. When configured in this way, a part of the coating liquid that has flowed out from the upper end opening of the tubular body can be stored in the coating liquid storage chamber with a simple structure.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

Has been. The inner wall 11 includes an upper large-diameter portion 14 and a lower small-diameter portion 15, and the upper large-diameter portion 14 is fitted in the mouth portion 4. The lower small-diameter portion 15 has a circular through hole 15b formed in the bottom wall 15a. The center of the through hole 15b is slightly lateral to the center of the bottom wall 15a (see FIG. 1 and FIG. In FIG. 2, it is positioned at a position shifted to the right). A cylindrical portion 16 is suspended from the bottom surface of the bottom wall 15a so as to surround the through hole 15b.

  Reference numeral 18 denotes a synthetic resin pipe (tubular body) that hangs down in the body portion 2. The lower end portion of the pipe is curved downward and the lower end opening is located near the bottom wall 2 a of the body portion 2. It is open. Further, the pipe 18 is inserted and fixed at its upper part (the part depending on the body part 2) through the through hole 15 b of the lower small diameter part 15 of the inner wall 11 and the central hole 16 a of the cylindrical part 16. Yes. Further, the upper end opening 18a of the pipe 18 opens into the coating liquid storage chamber 12, and a predetermined gap 19 (see FIGS. 5 and 6) is formed between the pipe 18 and a through hole 23 of the cap 21 described later. Positioned in the open position.

  Reference numeral 21 denotes a synthetic resin cap (cover), which is formed in a substantially cylindrical shape. As shown in FIG. 3, the cap 21 is provided with a second screw portion 22 that is screwed into the first screw portion 5 on the inner peripheral surface of the peripheral side wall 21 a. The cap 21 has a circular through hole (outlet) 23 formed at the center of the ceiling wall 21b, and surrounds the through hole 23 from the center of the upper surface of the ceiling wall 21b. A substantially cylindrical nozzle 24 (the central hole 24a serves as a liquid passage extending from the through hole 23) is projected. Further, the center of the through hole 23 (that is, the axial center of the through hole 23 and the central hole 24a) is positioned at the center of the ceiling wall 21b, whereby the center of the upper end opening 18a of the pipe 18 (that is, the center) The pipe 18 is slightly displaced laterally with respect to the axial center of the portion of the pipe 18 depending on the body 2 (see FIG. 4).

  Reference numeral 25 denotes an inner plug (see FIG. 1), which includes a disk part 25a and a convex part 25b that protrudes from the center part of the upper surface of the disk part 25a and fits in the through hole 23 and the center hole 24a in a liquid-tight manner. I have. In the inner plug 25, the coating liquid 6 in the container body 1 flows into the coating liquid storage chamber 12 from the upper surface opening 18 a of the pipe 18, and the coating liquid 6 accumulated in the coating liquid storage chamber 12 flows into the through hole 23. It works to prevent The inner plug 25 is used when the squeeze coating container of the present invention is transported or the like. However, after purchase, the purchaser may or may not attach it. Reference numeral 26 denotes an outer lid (see FIG. 1), which acts to cover the nozzle 24 of the cap 21.

  In the above configuration, in use, as shown in FIG. 5, the inner plug 25 and the outer plug 26 are removed and the nozzle 24 is directed upward or laterally (a little upward) to a desired portion. In this state, the body part 2 of the container body 1 is strongly gripped with fingers. As a result, the internal pressure of the container body 1 is increased, and the coating liquid 6 in the body portion 2 flows into the inside from the lower end opening of the pipe 18 and rises through the inside, and flows out from the upper end opening 18a. Then, the ink is fed into the through hole 23 of the cap 21, passes through the through hole 23 and the central hole 24 a of the nozzle 24, and is discharged from the tip opening of the nozzle 24 to the desired portion. Further, a part of the coating liquid 6 flowing out from the upper end opening 18a of the pipe 18 collides with a part of the outer peripheral portion of the through hole 23 (the right side portion in FIG. 5) and is scattered from the gap 19 to the periphery. The liquid is stored in the liquid storage chamber 12.

  On the other hand, when dripping the coating liquid 6 from the nozzle 24, as shown in FIG. 6, the container body 1 is tilted downward and the coating liquid 6 stored in the coating liquid storage chamber 12 is passed through the gap 19. It is dripped from the tip opening of the nozzle 24.
