Description

  The present invention relates to a cap with a gas venting function of a spray container for draining residual gas at the time of disposal after consuming the contents of the spray container. More specifically, the opening / closing door attached to the cap body is pushed inward. The present invention relates to a cap with a degassing function for a spray container that can easily open a valve and perform degassing by simply placing the spray container on the spray container.

The spray container is filled with contents such as paints, insecticides, cosmetics, and high-pressure gas for injecting them. The spray container after the contents are consumed is discarded, but the remaining contents and high-pressure gas are required to be completely removed. This is because the contents and high-pressure gas may be flammable, and further explode during disposal. Therefore, a cap that covers and protects the spray portion at the head of the spray container is provided with a gas venting function, and residual gas and contents in the spray container are completely extracted by the cap at the time of disposal.
The following are known as such caps with a gas venting function.
Japanese Patent Laid-Open No. 11-70986 JP 2002-173185 A

  As shown in FIG. 13, the cap with a gas venting function of Patent Document 1 is provided with a reverse locking plate c on the side wall b of the cap body a, and when the gas is vented, the reverse locking plate c is reversed inside. When the cap body a is put on the head of the spray container d, the reverse locking plate c pushes down the opening / closing stem e to open the valve, and the residual gas and contents in the spray container d are completely removed from the spray nozzle f. Can be sprayed outside.

  Further, as shown in FIG. 14, the cap with a gas venting function of Patent Document 2 is placed on the top plate g of the cap body a that covers and protects the head of the spray container d without contacting the stem e that opens and closes the valve. And a plurality of valve opening plates h that can be tilted toward the central portion, forming a cross connecting portion that maintains a tilted crossing state on the base end side of the plurality of valve opening plates h, and cross-connecting valves When the cap body a is put on the head of the spray container d, the intersection i of the open plate h is formed at a position that holds the valve open, and the cap body a is provided with a gas vent hole j. It will be.

  Then, when a plurality of valve opening plates h are tilted and intersected to form an intersection portion i by the intersection connecting portion, and the cap body a in this state is put on the head of the spray container d, the intersection portion i pushes down the stem e and the valve The residual gas and the contents in the spray container d can be completely injected into the cap body a from the spray nozzle f, and the residual gas is discharged to the outside through the gas vent hole j. If the content is liquid or powder, it is left in the cap body a.

  Since the cap with the gas venting function of Patent Document 1 has the reverse locking plate c on the side wall b, the reverse locking plate c is reversed regardless of whether or not the spray container d is put on the side wall b. If it is positioned by this reversal and directly covered on the spray container d, the contents are injected from the spray nozzle f together with the high-pressure gas. If the width of the reverse locking plate c is reduced in order to prevent the erroneous operation described above, it is difficult for the fingers to hit the side wall b when the reverse locking plate c is pushed during disposal.

  Moreover, although the cap with a gas venting function of patent document 2 does not have a misinjection like said patent document 1, the some valve | bulb open plate h protrudes in the inside, and the design of the spray nozzle f which is an injection button is carried out. It will be constrained. Moreover, it is difficult to apply to a cap having a small diameter, and it is difficult to form the valve opening plate h, and the amount of material used increases, resulting in an increase in cost.

  Therefore, the object of the present invention is that there is no erroneous operation regardless of whether or not the container is put on the container, the effort for venting is easy, and the structure is simple and the degree of freedom of design is sufficient. An object of the present invention is to provide a cap with a degassing function for a spray container that is excellent in performance.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, the cap body is mounted on the top of the spray container, and the opening / closing door that opens inward via a hinge is provided on the side wall of the cap body via a fragile portion that can be broken. ,
The opening / closing door is provided with a rib at the tip thereof, and at the upper end thereof, a reinforcing plate is formed in connection with the rib,
The open / close door is formed so as to be located on an operation member for opening and closing the valve of the spray container by breaking the fragile portion and opening the inside .
In addition, the cap body is provided with a stopper for opening / closing positioning of the valve with respect to the opening / closing door,
A cap with a degassing function for a spray container is provided.

  According to the present invention, there is provided a cap with a gas venting function for a spray container, wherein a plurality of the opening and closing doors are provided in the cap body.

  Moreover, according to this invention, the cap with a gas venting function of the spray container which provided the convex part which prevents the return of an opening / closing door when the said opening / closing door was opened inside is provided in the said cap main body.

  When the cap with a gas venting function of the spray container of the present invention is applied to the opening and closing door of the cap body and pressed to break the fragile portion, the opening and closing door opens inward via the hinge portion, When the cap main body is put on the spray container, the opening / closing door opened inside operates the operation member to perform the opening operation of the valve, and the residual gas in the spray container comes out and vents. Therefore, the effort for degassing is easy, and in addition, since the structure is simple, it is easy to make a mold and the like, and the productivity is excellent, and the degree of freedom in design is increased.

  Further, by providing a plurality of open / close doors, the open / close door and the operating member are more reliably engaged with each other, so that the valve can be opened more reliably. Moreover, if it forms in the position which a cap opposes, the effect will become still more reliable.

  In addition, when the weak part is broken by pressing the open / close door provided on the side wall of the cap body with your fingers, the open / close door opens toward the inner axis of the cap body and opens until it hits the stopper. When the cap body is put on the spray container, the open / close door opens the valve, and the residual gas in the spray container comes out and vents. Therefore, in addition to the above effect, there is an effect that the labor for degassing becomes extremely easy.

In addition, if the rib at the front end of the door and the reinforcing plate at the upper end are combined to increase the strength of the door , and the cap body is covered with a spray container, the strong door and rib will open the valve. The operation is performed, and the residual gas in the spray container can be extracted. Thereby, in addition to the above-described effects, there is an effect that there is no possibility that the distal end portion of the open / close door is deformed and the gas venting operation becomes impossible or the operation member does not hit and does not operate.

  Further, the opening / closing door can be opened inward and applied to the projecting portion, and the opening / closing door can be deformed to get over the projecting portion, and then the return of the opening / closing door can be regulated by the projecting portion. Thereby, in addition to the above-described effect, there is an effect that there is no possibility that the degassing operation due to the return of the front end portion of the open / close door becomes impossible.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

1 is a side view showing a cap with a gas venting function of a spray container of the present invention, FIG. 2 is a plan view showing a cap with a gas venting function of a spray container of the present invention, and FIG. 3 is a gas venting function of the spray container of the present invention. 4 is a sectional view taken along line IV-IV in FIG. 3, and FIG. 5 is a longitudinal sectional view showing an operating state of the cap with a gas venting function of the spray container shown in the first embodiment.
In the figure, a cap with a gas venting function (hereinafter simply referred to as “cap with a gas venting function”) 1 of a spray container is provided via a weakened portion 5 that can break an opening / closing door 3 that opens inside the cap body 4. The opening / closing door 3 is formed so as to be positioned on the operation member 6 that opens and closes the valve of the spray container 2 when the weakened portion 5 is broken and opened inside to cover the spray container 2. The container 2 is covered with a cap body 4 with the open / close door 3 open, and the operation member 6 is actuated to open the valve and remove residual gas.

  The spray container 2 has a cylindrical shape, and an upper part thereof is formed in a dome shape 10. A mountain cup 11 is provided at the center of the dome 10, and a part of a valve is formed at the center of the mountain cup 11. There is an operating member 6 for opening and closing the door. The operation member 6 is specifically a stem (not shown), and a push button 14 having an injection nozzle 13 is attached to the stem. Therefore, when the push button 14 or the stem is pushed, the valve is opened, and the contents filled with the high pressure gas in the spray container 2 are sprayed from the injection nozzle 13 by the pressure of the high pressure gas. In FIG. 4, reference numeral 15 denotes a slip stopper.

  The cap body 4 has a cylindrical shape and includes a top plate 20 and a cylinder 21 connected to the periphery of the top plate 20. The push button 14 and the operation member 6 are covered by covering the dome 10 of the spray container 2 with the lower end of the cylinder 21. The push button 14 or the operation member 6 is inadvertently pressed so that the valve is not opened and the contents are not sprayed to the outside. Two opening / closing doors 3 are provided on the side wall 22 of the cylinder 21 with an angle of 180 degrees, and these opening / closing doors 3 are positioned inside the top plate 20 and the thickness of the cylinder 21. Is provided. By forming in this way, it becomes possible to mold only with the upper and lower molds, and as in the case where the side wall b of Document 1 described above is cut into the reverse locking plate c, There is no need to split left and right.

  The base end side of the open / close door 3 is thin to form a hinge portion 23 so that the open / close door 3 can be easily opened and closed. The pressing position of the opening / closing door can correspond to various shapes depending on the shape of the push button, but in this embodiment, the form of pushing the shoulder portion of the push button is shown. When pressing the shoulder of the push button, a sufficient response is possible even when the door is pressed at a small angle. On the front end side of the open / close door 3, a bent rib 24 is formed at a substantially right angle, and on the upper end side of the open / close door 3, a reinforcing plate 12 is formed. Together, the ribs 24 and the reinforcing plate 12 increase the strength of the front end side of the door 3.

  The rib 24 serves to facilitate the position of the front end side of the opening / closing door 3 above the push button 14 or the operation member 6, and the rib 24 is sized along the outer diameter of the push button 14 or the operation member 6. In this embodiment (in this embodiment, the rib 24 is sized along the outer diameter of the operation member 6), the door 3 is pushed inward when the spray container 2 is covered with the cap 1 with the gas venting function. The possibility of erroneous operation such as accidental injection is eliminated. On the other hand, since the reinforcing plate 12 is provided, a part of the top plate 20 of the cap body 4 is cut away, so that when the open / close door 3 is pushed by fingers to break the fragile portion 5, the top plate 20. It is easy to break without hitting. The number of the open / close doors 3 may be one or three or more, and the number is not limited, but two are most convenient in terms of structure and residual gas venting function.

  The open / close door 3 is joined to the top plate 20 and the cylinder 21 by two upper joining bands 25 and a lower joining band 26 constituting the fragile portion 5. These upper and lower joining bands 25 and 26 are desirably strong enough to break even relatively weak children, women and the elderly. In addition, the weak part 5 does not depend on the upper and lower joining bands 25 and 26, but may be anything that can be broken even by a relatively weak person.

The top plate 20 of the cap body 4 is provided with a stopper 30 for performing opening / closing positioning of the valve with respect to the opening / closing door 3. The stopper 30 has a ring shape, but is not limited to this shape. The opening / closing door 3 is opened inward, that is, the opening / closing position of the valve, that is, the tip of the opening / closing door 3 is at least vertically above the operation member 6. Any shape can be used as long as the door 3 can be stopped at this position. Further, after the opening / closing door 3 is opened inward until it hits the stopper 30, the cap body 4 is provided with a return preventing projection 31 so that the opening / closing door 3 does not return from the opening / closing position of the valve. The convex portion 31 includes a main body side convex portion 31 a provided on the top plate 20 and a door side convex portion 31 b provided on the upper end of the open / close door 3, and the door side convex portion 31 b of the open / close door 3 is the main body side of the top plate 20. By getting over the convex portion 31a, the door 3 is prevented from returning.
The plurality of opening / closing doors 3 are provided on the side wall 22 of the cap body 4 by being rotated by, for example, 180 degrees, but needless to say, they may be provided arbitrarily.

Next, the usage method of the cap 1 with a gas venting function which becomes the said structure is demonstrated.
In FIGS. 1 to 4, the contents are stored in the spray container 2, and the cap 1 with a gas venting function is attached to the dome 10 of the spray container 2, and the contents in the spray container 2 are not inadvertently sprayed. This shows the state of protection. If the contents in the spray container 2 are consumed, the spray container 2 becomes unnecessary and is discarded. However, at the time of this disposal, the high-pressure gas for spraying the contents remains in the spray container 2 and is discarded. Then, since there is a risk of explosion in subsequent processing steps, it is necessary to vent the residual gas.

  First, remove the cap 1 with the gas venting function from the spray container 2, press the fingers against the open / close doors 3 and 3 and break the upper bonding band 25 and the lower bonding band 26 of the fragile portion 5 to open the inside. When the door-side convex portion 31b of the open / close door 3 gets over the main body-side convex portion 31a of the top plate 20 and further opens inward until the door 3 hits the stopper 30, even if the finger is released from the open / close door 3, the convex portion 31 The opening / closing door 3 does not return to its original position, and the opening / closing door 3 is positioned vertically above the opening / closing position of the valve. Thereafter, when the cap 1 with a gas venting function is put on the dome 10 of the spray container 2, the open / close door 3 hits the operation member 6 and pushes further downward, opens the valve, and from the injection nozzle 13 attached to the push button 14. Residual gas in the spray container 2 is sprayed and degassed for disposal.

  FIGS. 7 to 10 show a cap with a gas venting function of another spray container of the present invention. The difference between the cap with gas venting function 1a and the cap with gas venting function 1 in FIGS. When the height of the opening / closing door 3a is reduced and opened inside, the opening / closing door 3a can be opened to the valve opening / closing position, that is, the position above the push button 14 in the vertical direction. is there. That is, in this example, since the door is pushed by pushing the top of the push button, it is possible to cope even when the height of the door is low. Therefore, if the cap 1a with a gas venting function in a state where the opening / closing door 3a is opened on the inner side up to a position above the push button 14 is put on the dome 10 of the spray container 2, the opening / closing door 3a becomes the push button 14 When the valve is pushed further downward, the valve is opened, and the residual gas in the spray container 2 is sprayed from the spray nozzle 13 attached to the push button 14, and the gas is vented to be discarded. Since other configurations and operations are the same as those of the cap 1 with the gas venting function shown in FIGS. 1 to 6, the drawings are denoted by reference numerals and detailed description thereof is omitted.

11 and 12 show a cap with a gas venting function of another spray container according to the present invention. The difference between the cap with gas venting function 1b and the cap with gas venting function 1 in FIGS. The top plate 20 is provided with a stopper 30a that is a simple protrusion for positioning the valve from an endless ring shape, and a front end convex portion 31c that engages with the stopper 30a is provided at the front end portion of the open / close door 3. When the door is pushed in, the opening / closing door 3 can be stopped at a position where the tip is at least vertically above the operation member 6. In the case where the front end of the open / close door has a convex portion for preventing the return, when the door is pushed in, the opposing door may be engaged with the front end convex portion and positioned on the push button.
Other configurations and operations are the same as those of the cap 1 with a gas venting function shown in FIGS.

  As mentioned above, although Embodiment 1 thru | or 3 of this invention was demonstrated, it should be understood that a specific structure is not limited to this and the change in the range which does not deviate from the summary of this invention is possible suitably. .

  The present invention is highly applicable to cases where it is easy to vent the gas, but it is desired to completely prevent the occurrence of erroneous operation regardless of whether or not the container is covered. When it is desired to obtain a product with excellent properties, the applicability becomes extremely high.
