Description

Aerosol container with cap Technical field

TECHNICAL FIELD The present invention relates to an aerosol container with a cap, and particularly to an aerosol container having a cap that can be used to safely and easily extract pressurized gas for injection housed in the aerosol container. . Background art

Conventionally used aerosol containers are generally widely used for spraying paints, cleaning agents, hair styling agents, fragrances, insecticides, and other chemicals. Along with the active ingredients such as, a pressurized gas for easily spraying these ingredients out of the container in the form of a mist and a solvent that easily vaporizes are stored as contents. When the above-mentioned aerosol container is used or discarded when it is no longer needed, the pressurized gas for spraying or the vaporized solvent remains inside the container, and the container is incinerated as it is. May cause an explosion accident, and the remaining active ingredients may not always be harmless. Therefore, it is desired to be discarded.

Therefore, when a used or unused aerosol container is discarded, as a means for extracting gas and active ingredients remaining in the container, conventionally, a nail wall or a drill is used to manually remove the body wall of the aerosol container. There is a method of piercing and extracting gas, or a method of preparing a special piercing device and ejecting gas and active ingredients to extract. However, the former method has a problem in terms of safety and hygiene because the contents such as gas ejected to the person performing the drilling work fall down, and furthermore, the contents such as paints and the like are removed together with the gas. It may erupt and pollute nearby people and places. In the latter case, special drilling equipment must be installed. The installation site and installation cost were expensive, and it was not suitable for ordinary households or individuals.

In order to solve the above problems, an aerosol container with a cap having the following degassing means has been proposed.

(1) As shown in FIG. 18A, a fitting recess 105 is formed on the top wall of the cap 101, which substantially matches the contour from the mounting cup 104 of the container body 103 to the rod-shaped injection head 102, and as shown in FIG. When the cap is turned over and the periphery of the fitting recess 105 is fitted to the outer periphery of the mounting cup, the rod-shaped ejection head 102 abuts against the inner surface of the fitting recess and is pushed down, and a part of the fitting recess is formed. A gas is exhausted from the gas vent hole 106 formed in the above (refer to Japanese Patent Application Laid-Open No. Hei 10-53289).

(2) As shown in Fig. 19, a part of the inclined cap top wall is cut off, leaving one lower side, and the other side is cut off to form a pressing piece 110 having one lower side as an elastic bent portion 110a. A device provided so as to push down the ejection head 111 through a piece (see Japanese Utility Model Publication No. 3056237).

③ In a tilt-type aerosol container that ejects the contents by tilting the injection head rising from the container body forward, part of the rear wall of the cap fitted to the upper part of the container body is cut off on the upper and lower sides. The elastic strip is capable of reversing the elasticity inward into the cap, and is provided so that the jet head is pushed forward and tilted forward by the inward reversal of the elastic strip (Japanese Patent Application Laid-Open No. -70986).

中心 The center portion of the cap top wall is formed as a convex (plated-down) elastic plate portion, and the pressing protrusion protrudes downward from the lower surface of the flexible plate portion, and the elastic plate portion is elastically inverted downward to thereby form the pressing protrusion. Provided so as to push down the ejection head (see JP-A-2001-019067).

However, the container (1) tends to be contaminated by dust adhering to the fitting recess during use, the container (2) cannot be vented unless the pressing piece is kept pressed, and the container (3) is a tilt type. There is a disadvantage of being limited. Further, in case (2), the evacuation may be suddenly started or stopped because the elastic plate portion is elastically inverted or elastically restored by contact with another object during normal use or degassing operation.

As a container that solves these problems, the present applicant has already A part of the peripheral wall is formed as a bent plate toward the inside of the cap. The bending opens an opening for degassing, and the bent plate is fixed inside the cap. We have proposed an aerosol container with a cap provided to keep the pressure down (JP-A-2000-191062).

In the present invention, this container is further improved or changed to further improve the usability. Disclosure of the invention

A first object of the present invention is to open a gas vent opening by bending a part of a top wall or a peripheral wall of a cap inwardly of a cap, and a method of bending a bent plate bent inwardly into a cap. An object of the present invention is to provide an aerosol container with a cap that can be continuously used with the same finger to perform the operation of locking it to the inner stopper. In order to achieve this object, a container body for erecting a jet head and a cap fitted on the upper part of the container body are provided. A part of the peripheral wall or top wall of the cap is formed by a bending line and a breaking line. A bent plate that can be enclosed and bent inward by breaking the break line is provided, and a stopper that locks the bent plate in a bent state is provided, and the ejection head is pushed down to release gas from the container body. In the aerosol container with a cap, the bent plate locked to the stopper comes into contact with the top surface of the injection head to maintain the pressed state.

The opening formed by the inward refraction of the above-mentioned bent plate is made into a large finger insertion hole and gas vent hole through which the user's finger can be inserted, and the bent plate is pushed in to break the breaking line. An aerosol container has been proposed in which a finger is further inserted into the opening so that the bent plate can be engaged with the stopper.

A second object of the present invention is to prevent a bent plate from being suddenly degassed or locked by locking the bent plate in the stopper with a finger inserted through the opening and locking the bent plate inside the cap. It is to prevent that.

In order to achieve this object, in the present application, in the above-mentioned aerosol container, a part of the top wall or the peripheral wall of the cap is formed as a bent plate capable of bending inward of the cap. A structure has been proposed in which a bent plate or a pressing plate portion protruding at a right angle from the bent plate as a part of the bent plate is engaged with a stopper which is vertically provided from the back surface of the cap top wall.

Further, as another structure capable of locking another bending plate, a pair of bending plates are provided on the top wall of the cap so as to face each other when the cap is bent inward, and on the lower surface of each of these bending plates. A device having first and second fitting means that can be fitted to each other when facing each other is proposed.

A third object of the present invention is to provide a bent plate bent from the top wall of the cap so as to forcibly climb over the corner of the ejection head to push down the ejection head and maintain the pushing down. While the cap is still attached to the container, forming an opening by bending the bent plate, pressing down the ejection head, and locking the bent plate in the pressed state as a series of operations. Is to be able to do it.

A fourth object of the present invention is to provide a chamfered portion for facilitating the bent plate to ride on the corner of the jet head at any of the corner of the jet head and the free end of the bent plate. It is to form.

Other objects of the present invention will be clarified in the following description. BRIEF DESCRIPTION OF THE FIGURES

In this specification, the concepts of “front and rear” and “left and right” are used as necessary to show the positional relationship between members.

The container body 2 has a jet head 3 with a nozzle 4 with a front opening opened upright through a stem (not shown) urged upward from an upper wall thereof. The ejection head according to the present embodiment is configured as an ejection head capable of ejecting a liquid by staking and pushing down the urging force. The upper wall of the container body is connected to the outer peripheral wall via a winding end 7 formed on the peripheral edge.

The cap 11 hangs down the peripheral wall 12 from the peripheral edge of the cap top wall 14. Reference numeral 13 denotes an engagement means (an engagement rib or the like) attached to the lower edge of the cap peripheral wall. The engagement means 13 is pressed against the ejection head in a state where the ejection head is pushed down by a cap, which will be described later. Provided so that engagement can be maintained. The cap is desirably formed of a flexible material such as a synthetic resin material.

A part of the cap top wall 14 was formed on a bent plate (or lid) 17 surrounded by a bending line 18 such as a thin hinge and a breaking line 19 as shown in FIG. 2, and the breaking line 19 was broken. Then, as shown in Fig. 4, the bent plate 17 is moved inward of the cap with the refraction line 18 as the center. The opening 15 is provided such that the opening 15 is formed inside the breaking line 19 and the bending line 18 by refraction. The opening has only to have a sufficient size as a gas vent hole and a hole for a user's finger, and its shape can be changed as appropriate. In the preferred embodiment, the refraction line 18 is linear and the break line is a certain distance from the periphery of the cap top wall 14? It is formed in an arc shape. The break line may be one obtained by connecting a suitable portion of the cut line at a break portion 19L as shown in the figure, or may be a thin break portion.

In the present embodiment, as shown in FIG. 2, the opening 15 is disposed at a position eccentric with respect to the center axis c of the ejection head 3 (in the illustrated example, behind the center axis), and A bending line 18 is provided between the front edge of the opening and the front end (or fixed end) 17a of the bent plate adjacent thereto. Further, the bent plate 17 has a wide pressing plate portion 20 extending in the left-right direction from the back surface thereof, and from the front half of the cap top wall 14, the bending line 18 and the injection are formed. The central axis c of the pad 3 is sandwiched between the push-down plate 20 and the plate-shaped stopper (or locking plate) 21 facing the push-down plate. As shown in FIG. 3, an engagement projection 22 is formed at one of the lower ends of the press-down plate portion 20 and the stopper 21, and a notch-shaped engagement recess 23 is formed at the other. When the bent plate 17 is bent toward the inside of the cap, the engagement projection 22 is fitted into the engagement recess 23 as shown in FIG. It is provided so that it can be locked and locked. According to the above configuration, the outer surface of the bent plate 17 is substantially flush with the outer surface of the cap top wall 14 in the initial position shown in FIGS. 1 and 3, and the opening 15 is formed as a part of the top wall.

When discarding the container, from the state shown in Fig. 1, first remove the cap from the upper part of the container body 2 and then push down on the upper surface of the bent plate # 7. Pivots about the refraction line 20 to the second position where it hangs inward of the cap, whereby the engaging projections 22 and the engaging recesses 23 engage, and the bent plate 17 Is locked by. When the cap is re-fitted to the container body 2 in this state, the press-down plate portion 20 presses down the upper surface 5 of the spray head 3 of the aerosol container and maintains the pressed state, so that gas is released. To It can be carried out. In this state, since the bent plate 17 is located inside the top wall 14 and the peripheral wall 12 of the cap and hardly comes into contact with other objects, the user temporarily discards the aerosol container in the middle of degassing in a trash box or the like. Even so, it is unlikely that the above-mentioned contact will release the pressed state of the injection head.
