Description

  The present invention relates to a nozzle safety device for a spray container in which a fluid is stored together with a high-pressure gas in a container body, and the nozzle provided on the upper part of the container body is pushed down with a fingertip to eject the internal fluid.

  Spray containers that inject internal fluid from nozzles are generally widely distributed as aerosol products such as insecticides, paints, pharmaceutical liquids, cosmetic liquids, and liquids for self-protection, but in such spray containers, no injection is required. In order to prevent the nozzle from being pushed down accidentally, a nozzle safety device is provided at the top of the container body.

  As a conventional nozzle safety device, generally, a cap that covers the nozzle is detachably attached to the upper part of the container body, and the nozzle cannot be pushed down unless the cap is removed (for example, patent document). 1).

  However, since the removable cap cannot push the nozzle until it is removed, not only can one-touch injection be performed, but the removed cap must be stored separately, and there is a risk of loss.

  In order to eliminate the problem associated with such a separate cap, a cylindrical base part lower than the upper surface of the nozzle is rotatably attached to the upper part of the container body so as to surround the nozzle, and the upper end part of the base part is provided. A cap is provided on the outer periphery via a hinge, and this cap is placed on the base so that the nozzle cannot be covered and pushed. By removing the cap from the base and exposing the nozzle, injection can be performed by pushing down the nozzle. A safety device has been proposed (see, for example, Patent Document 2).

Japanese Utility Model Publication No. 6-64747 JP-A-6-13457

  By the way, the safety device having the structure in which the cap is provided on the cylindrical base portion through the hinge has an advantage that the cap is not lost, but the base portion and the cap are rotatable with respect to the container body. Therefore, there is no relationship between the opening direction of the cap and the injection direction of the nozzle, and it is necessary to check the injection direction by looking at the nozzle direction with the cap open, and the opened cap may interfere with the injection. There is a problem that the direction of injection is not fixed when it is desired to use it in a hurry.

  In addition, the base part is a cylindrical shape that fits over the body part of the container body, and the cap is structured so as to cover it from above. There is a problem in that the cost is high.

  Furthermore, when the cap is opened, the upper end of the nozzle protrudes above the upper end of the base, so there is nothing to suggest or regulate the nozzle injection direction, and the injection direction is not fixed. When the cap is opened, the nozzle can be pushed immediately, so there is a high possibility that erroneous injection occurs and the function as a safety device is low.

  Therefore, an object of the present invention is to provide a spray container that is small in size, low in production cost, easy to check the injection direction, can be injected with a single touch, and can improve the function as a safety device by reducing the occurrence of erroneous injection. It is to provide a nozzle safety device.

  In order to solve the above-described problems, the present invention is directed to an upper end portion of a container main body, a nozzle that injects fluid in the container main body by being pushed down, and a cylindrical shape that surrounds the periphery of the nozzle. A protective cylinder having a height higher than the above is provided, and the protective cylinder has a window hole at a position corresponding to the nozzle injection hole at a part of the peripheral wall, and the opposite side of the peripheral wall from the upper end of the protective cylinder. The opening part for operation in which the fingertip for pushing down the nozzle is fitted is provided in the part, and the opening part of the operation opening part is provided at the upper end of the protective cylinder so that the nozzle cannot be pushed down with the cover closed. A lid member that opens the upper part of the opening part for operation is provided to be able to move up and down so that the nozzle can be pushed down in an open state where the upper part is covered. Provided with a pair of engaging portions that elastically hold the closed state of the lid member A.

  The lid member is formed in a circular shape having substantially the same diameter as the outer diameter of the protective cylinder, and the lid member and the protective cylinder are made of synthetic resin and integrated with a hinge that can be bent at the upper position of the window hole in the protective cylinder. The pair of engaging portions are formed on the upper surface of the protective cylinder along the inner periphery of the opening portion for operation, and on the lower surface of the lid member. Thus, it is possible to have a structure formed of a cylindrical portion that is elastically fitted to the inside of the ridge.

  Here, the protective cylinder has a cylindrical shape in which the inner diameter is just fitted to the head of the nozzle that can be pushed down on the upper part of the container body, and the operation opening portion has an insole from the upper end of the protective cylinder. It has a depth that reaches the middle part of the upper and lower dimensions. At the upper end of the protective cylinder, it becomes a flat U shape with a width that fits the fingertip, and the peripheral wall opens from both ends of the U shape to reach the insole, and this opening for operation By inserting a finger into the part, the nozzle can be pushed down with a head protruding above the insole.

  When the lid member is in the closed state where it is tilted to the upper part of the protective cylinder, the upper surface of the opening part for operation is closed, and the opening part of the peripheral wall of the opening part for operation becomes narrow, so that the nozzle head can be pushed from the outside. It will be covered so that there is no.

  Also, when the lid member is pushed open from the part opened by the peripheral wall of the opening part for operation, the upper surface of the opening part for operation is opened, and the nozzle can be pushed down by the head. Since the positional relationship between the nozzle and the nozzle injection hole is constant, the nozzle injection direction can be known by placing a finger along the front-rear direction of the opening portion for operation.

  According to this invention, the protective cylinder surrounding the nozzle includes the opening part for operation in which the fingertip for pushing down the nozzle fits, and the lid member for opening the upper part of the opening part for operation is raised and lowered at the upper end part of the protective cylinder Since it is provided so as to be movable, the upper part of the nozzle is covered with a lid member so that the fingertip cannot be inserted into the opening for operation, the nozzle can be prevented from being pushed down by mistake, and the occurrence of erroneous injection is reduced. Thus, the function as a safety device can be enhanced, and if the lid member is pushed up with the fingertip, it is possible to promptly eject with one touch.

  In addition, since the lid member is located higher than the nozzle, it does not obstruct the injection, and the direction of the fingertip of the opening part for operation formed in the protective cylinder and the direction of the injection hole of the nozzle are constant. It is easy to check the injection direction, and there is no mistake in the injection direction.

  Furthermore, since it is comprised by the protection cylinder surrounding a nozzle, and the cover member provided in the upper part, size reduction of a safety device is attained and manufacturing cost can be made cheap by reduction of the material to be used.

A protective cylinder 5 having a height higher than that of the nozzle 4 is provided, and the head 4a of the nozzle 4 is pushed down so that the internal pressure fluid to which the gas pressure is applied is injected from the injection hole. .

  As shown in FIG. 4, the protective cylinder 5 has a cylindrical shape that is externally fitted to the head 4 a of the nozzle 4, and a window hole 6 at a position corresponding to the injection hole 4 b of the nozzle 4 at a part of the peripheral wall 5 a, An opening portion 7 for operation in which a fingertip for pushing down the nozzle 4 is fitted to a portion of the peripheral wall 5a opposite to the window hole 6 from the upper end of the protective cylinder 5 is provided, and the upper end is slightly higher than the upper surface of the head 4a. Has a height dimension.

  At the upper end of the peripheral wall 5a of the protective cylinder 5, a lid member 8 that opens and closes the upper part of the opening portion 7 for operation is provided so as to be able to move up and down, and the lid that is laid down on the upper surface of the lid member 8 and the protective cylinder 5 A pair of engaging portions 9 that elastically hold the closed state of the member 8 are provided.

  The opening part 7 for operation formed in the protection cylinder 5 has the depth from which the insole 5b reaches the substantially intermediate part of an up-down dimension from the upper end of the protection cylinder 5, and the plane U of the width | variety which a fingertip fits in the upper end of the protection cylinder 5 In the peripheral wall 5a, an opening is made so as to reach the insole 5b from both ends of the U-shape, and by inserting a finger into the opening portion 7 for operation, the nozzle 4 is projected by the head 4a protruding above the insole 5b. Can be pushed down.

  The relationship between the opening portion for operation 7 and the nozzle 4 is such that the injection hole 4b of the nozzle 4 faces forward with respect to the front-rear direction of the opening portion for operation 7.

  The lid member 8 is formed in a circular shape having substantially the same diameter as the outer diameter of the peripheral wall 5a of the protective cylinder 5, and the lid member 8 and the protective cylinder 5 are made of synthetic resin and are positioned above the window hole 6 in the protective cylinder 5. The cover member 8 is integrally formed via a bendable hinge 10 at the top of the opening portion 7 for operation so that the nozzle 4 cannot be pushed down in the closed state as shown by the solid line in FIG. The upper part of the opening part 7 for operation is open | released so that the nozzle 4 can be pushed down in the open lid | cover state like the dashed-dotted line in the figure.

  The pair of engaging portions 9 are provided on the upper surface of the peripheral wall 5a of the protective cylinder 5 along the inner surface of the opening portion 7 for operation, and on the lower surface of the lid member 8. The lid member 8 is formed with a cylindrical portion 9b that is elastically fitted to the inside of the protrusion 9a when the lid member 8 is closed, and the lid member 8 in the closed state is positioned at the position of the opening portion 7 for operation. If you flip it up with your fingertips, you can easily make the lid open.

  As described above, by forming the protective cylinder 5 in a cylindrical shape surrounding the outside of the nozzle 4, the overall outer shape can be reduced, the material used can be reduced, and the protective cylinder 5 is made of synthetic resin. By integrally molding the lid member 8, the structure can be simplified, and a cost-effective safety device is obtained.

  Examples of aerosol products using the spray container 1 include insecticides, paints, pharmaceutical liquids, beauty liquids, liquids for self-protection, etc. The portable small size that can be stored can be selected according to the product.

  The spray container nozzle safety device of the present invention is configured as described above, and when the spray container 1 is not used, the lid member 8 is turned down toward the protective cylinder 5 as shown in FIGS.
