Description

  The present invention relates to an aerosol container that facilitates discharge of residual gas and removal work at the time of disposal.

  The aerosol container accommodates the contents and the gas for injection inside, and when the injection button assembled on the upper part is pressed, the contents are injected from the injection port using the pressure of the gas. Usually, such aerosol containers are injected with more gas so that the gas for injection remains inside even after the contents are poured out. Need to be released.

  Conventionally, as a method for dissipating residual gas to the outside, there have been known inventions such as making a hole directly in a container or attaching a valve button for pressing a valve to the container to open the valve.

  In addition, the aerosol container may be devised such as providing a shoulder cover on the outer periphery of the upper part, protecting fingers from exposed metal end faces, improving the appearance, or making the overcap assembly comfortable. is there.

  However, since the aerosol can containing the gas for injection is usually made of metal, it takes time and effort to make a hole such as driving a sharp tool into the aerosol can. In addition, the residual gas remaining in the can at the moment when the hole was pierced, and there was a risk that the hand would become unstable and the chips when it was evacuated would fly to the face and eyes. Moreover, when attaching a valve button to a container and releasing residual gas, it was necessary to attach a valve button to all the containers separately, and it was expensive.

  When disposing, it is necessary to separate the metal aerosol can from the resin shoulder cover and spray button. However, it is difficult to grasp the shoulder cover because it is originally formed so that it is less likely to get caught, and in addition, it is not easy to remove the shoulder cover from the aerosol can because it is assembled relatively firmly so that it does not come out accidentally. It was.

  Further, in the case of an aerosol container with a shoulder cover assembled, the number of components to be constructed has increased, and the manufacturing of the components and the assembly process of the components have become troublesome, leading to an increase in cost.

  It is an object of the present invention to provide an aerosol container with a shoulder cover that can easily and easily dissipate residual gas, easily separate resin components for disposal, have a small number of parts, and can be easily assembled. To do.

  1. An aerosol can in which the contents are stored together with a gas for injection, an injection button for pressing the extraction pipe to eject the contents, and an upper portion of the aerosol can. In an aerosol container consisting of a shoulder cover and an overcap that can be detachably attached to the shoulder cover, the overcap can be assembled to the upper outer periphery of the aerosol can, and when the overcap is assembled to the upper outer periphery of the aerosol can, It was formed so as to be pushed down to the position where the contents were ejected.

  The assembling force when the overcap is directly assembled to the upper outer periphery of the aerosol can is an assembling force sufficient to continuously inject residual gas by pressing the injection button. The overcap is not only pressed by directly contacting the inner surface of the top wall of the overcap, but also formed in advance on the inner surface of the top wall of the overcap, etc. so that the injection button can be depressed. Good.

  In the aerosol container described in 2 or 1, the overcap can be assembled to the upper outer periphery of the aerosol can with a larger assembly force when the overcap is assembled to the shoulder cover. The assembling force is changed, for example, by changing the outer diameters of the shoulder cover and the upper portion of the aerosol can or changing the assembling shape. In addition, you may provide the hole etc. for discharging | emitting residual gas out of an overcap in an overcap.

  In the aerosol container according to 3, 1 or 2, the shoulder cover is composed of an outer ring body assembled to the outer periphery of the upper portion of the aerosol can, and an inner ring body provided with a knob piece inside the outer ring body, Consists of a hinge that detachably connects the outer ring and inner ring at positions facing the knob pieces, and a first connecting piece that detachably connects the outer ring and inner rings around the knob piece. did.

  The 1st connection piece is formed in the intensity | strength broken by the operation | movement which pulls up a knob piece. The hinge is formed with sufficient strength to pull out the outer ring from the aerosol can when the outer ring is pulled up by holding the knob piece or the inner ring. The hinge and the knob piece are preferably provided at positions facing each other across the center of the shoulder cover, but each may be provided at a position shifted from the facing position.

  4. The aerosol container according to any one of claims 1 to 3, wherein the shoulder cover and the spray button are separable and integrally connected to each other by a second connecting piece having a breaking strength lower than that of the first connecting piece. When assembled to the can, the injection button was assembled to the dispensing tube and the second connecting piece was broken so that the shoulder cover and the injection button were separated.

  In this case, it is preferable that the spray button and the shoulder cover are integrally formed so that the spray button can be directly assembled to the dispensing pipe by assembling the shoulder cover to the aerosol can, and after the spray button is assembled to the dispensing pipe. It is more preferable that the shoulder cover is further pulled down so that the second connecting piece is broken and the shoulder cover is assembled to the aerosol can.

  The second connecting piece is formed so as to be broken before the first connecting piece. The second connecting piece only needs to be formed at least one place between the shoulder cover and the injection button, but it is preferable that the second connecting piece be in a symmetrical position from the viewpoint of assembling the shoulder cover. Furthermore, the 2nd connection piece may be formed over the perimeter of the injection button.

  Further, the second connecting piece may be broken not only by the operation of assembling the shoulder cover to the upper outer periphery of the aerosol can, but also by the operation of pressing the spray button after the shoulder cover is assembled. .

  The aerosol container of the present invention has the following effects.

  Since the shoulder cover is provided, the overcap can be attached and removed with an appropriate operational feeling.

  By assembling the overcap directly on the top of the aerosol can from which the shoulder cover has been removed, the residual gas can be easily and completely dissipated from the aerosol can without requiring a separate part by pressing the spray button.

  By strengthening the assembling force between the aerosol can and the overcap, it can be used as an overcap with good operability during normal use, and when the residual gas is released, it is firmly attached to the aerosol can to reliably release the residual gas. Can be made.

  By lifting the handle piece of the shoulder cover, the inner ring body can be first lifted obliquely, and subsequently, the outer ring body can be pulled out from the aerosol can, and the shoulder cover can be easily removed from the aerosol can.

  Since the injection button and the shoulder cover are molded as one part, the manufacturing cost can be reduced. By attaching the shoulder cover to the top of the aerosol can, the spray button can be assembled to the dispensing pipe, and the shoulder cover and spray button can be separated, providing an aerosol container with a shoulder cover in a simplified assembly process it can.
