Description

The present invention relates to a cover cap used in an aerosol container having an ejection button, and an aerosol container using the same.

Various aerosol products are sold that are configured to eject contents from an ejection port by pressing down on an ejection button. This type of aerosol product is constructed by filling an aerosol container with contents (for example, cosmetics or hair styling products) together with a propellant such as LPG gas. Then, when the user presses down the injection button, the contents filled in the aerosol container are energized by the propellant and are injected to the outside from the injection port.

Many of these aerosol containers are equipped with a cover cap to prevent malfunction when not in use. This kind of cover cap has walls that are higher than (or the same height as) the top surface of the injection button on the left and right sides of the injection button, and the presence of these walls prevents malfunction ( For example, Patent Document 1). In other words, when carrying an aerosol product in a bag, etc., the wall of the cover cap prevents the ejection button from accidentally hitting even if it receives an external shock or comes into contact with other items inside the bag. This prevents the contents from squirting out due to being pushed down.

Japanese Patent Application Publication No. 2011-105342

In a cover cap for preventing malfunction, if a wall is formed all around the injection button, it becomes difficult to push down the injection button when using an aerosol product. For this reason, the cover cap is provided with an operation recess for making it easier for the user to place his/her finger on the injection button.

In the conventional cover cap, such an operation recess is formed at a position opposite to the injection port (at a position of 180° when the position of the injection port is 0° in plan view). This is because when a user uses an aerosol product, it is assumed that the user places his or her finger on the injection button from the side opposite to the injection port. Further, the angular range in which the operation recess is formed in the cover cap is not very wide, and is approximately 120° to 240° at most.

However, in an aerosol product (such as a deodorant spray) in which the user faces the nozzle toward himself or herself, the user presses the ejection button while twisting the wrist in a configuration in which the operation recess is provided at a position opposite to the nozzle. Need to press. This puts a strain on the user's wrist.

The present invention has been made in view of the above-mentioned problems, and provides an aerosol container that allows the user to press the ejection button without putting strain on the user's wrist in an aerosol product in which the ejection port is directed toward the user himself/herself. The purpose is to provide cover caps and aerosol containers.

In order to solve the above problems, a cover cap for an aerosol container, which is a first aspect of the present invention, is used for an aerosol container having an injection button and is disposed at the top of the container body. has a central hole formed to surround the periphery of the ejection button and expose it so as to be movable up and down; and around the central hole, there is a portion of the ejection button that has not been pressed down. A wall portion having a top that is higher than the top surface, and an operation recess provided as a recess for a user to place a finger on the injection button are provided, and the operation recess is provided in a clockwise direction in a plan view. When indicating the angular position and assuming that the position where the injection port of the injection button exists is a reference position at an angle of 0°, the operating recess is formed to include at least one of angular positions of 270° and 90°. It is characterized by the presence of

According to the above configuration, when the above aerosol container is used in an aerosol product in which the injection nozzle is directed toward the user himself/herself, the user can press the injection button from an angular position of 270° or 90° via the operating recess. You can press the injection button without putting strain on your wrist.

Further, in the cover cap of the aerosol container, the operating recess may be formed in a configuration in which the angle range includes a range of 90° to 270°, or in three positions of 90°, 180°, and 270°. The configuration may be formed in an angular position.

According to the above configuration, the user can press down the injection button from three directions: opposite to the injection port, right side, and left side.

Furthermore, in order to solve the above problems, an aerosol container according to a second aspect of the present invention is characterized by being equipped with the cover cap described above.

The aerosol container cover cap and aerosol container of the present invention are an aerosol product that is used with the injection nozzle facing the user himself/herself, and the user can place his or her finger on the injection button through the operation recess from an angular position of 270° or 90°. This has the effect that the user can press the ejection button without putting any strain on the user's wrist.

[Embodiment 1]
Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of an aerosol container 10 according to the present embodiment.

As shown in FIG. 1, the aerosol container 10 includes a container body 11 in which contents are stored, an injection button 12 attached to a stem (not shown) of the container body 11, and an injection button 12 that is fitted onto the top of the container body 11. The cover cap 20 is configured to include a cover cap 20. The injection button 12 is provided with an injection port 121. For convenience of explanation, the side where the injection port 121 is present in the aerosol container 10 will be referred to as the front side.

In a product using the aerosol container 10 (hereinafter referred to as the present aerosol product), when the user presses down the injection button 12 with his or her fingertip to lower it, the stem resists the urging force of an elastic member (not shown) inside the container body 11. and is pushed down. As a result, the contents inside the container body 11 are injected from the injection port 121. When the user releases the depression of the injection button 12, the stem returns to the upper limit position by the urging force of the elastic member, and the injection of the contents of the container body 11 is completed.

FIG. 2 is a perspective view of the cover cap 20. FIG. 3 is a plan view of the cover cap 20. As shown in FIGS. 2 and 3, the cover cap 20 has a substantially cylindrical shape with a central hole 21 formed to surround the injection button 12 and expose it so as to be vertically movable. The outer diameter of the lower end of the cover cap 20 is, for example, the same dimension as the outer diameter of the container body 11.

In the cover cap 20, the center hole 21 is surrounded by an injection recess 22, an operation recess 23, and a wall 24. The injection recess 22 is a recess formed on the front side of the cover cap 20, exposes the injection port 121, and is provided so that the cover cap 20 does not interfere with injection. The operation recess 23 is a recess formed on the rear side of the cover cap 20, and is provided to make it easier for the user to place his or her finger on the injection button 12 when using this aerosol product.

The wall portion 24 is provided to protrude upward in the circumferential direction of the cover cap 20 between the injection recess 22 and the operation recess 23 (that is, at two locations on the left and right). The wall portion 24 is formed such that its top portion is higher than the top surface of the injection button 12 that is not pressed down. As a result, when this aerosol product is carried in a bag or the like, the wall portion 24 prevents the injection button 12 from being damaged even if it receives an external shock or comes into contact with other items inside the bag. This prevents the contents from spewing out due to being pushed down too easily.

FIG. 4 is a plan view of the aerosol container 10. In this embodiment, the angular position is shown in a clockwise direction when viewed from above, and the position where the injection port 121 of the aerosol container 10 is located is defined as the reference position (angle 0°).

The aerosol container 10 is characterized in that the angular range in which the operation recess 23 is formed in the cover cap 20 is made wider than before, thereby improving usability for the user. That is, as shown in FIG. 4, the operating recess 23 is formed so that the angular range includes the range of 90° to 270° (preferably wider than the range of 90° to 270°). has been done.

By widening the angular range of the operation recess 23 in this way, this aerosol product allows the user to use the product by placing his/her finger on the injection button 12 from the side opposite to the injection port 121 (see FIG. 5(a)). In addition, when the user uses the injection port 121 toward himself/herself, the user can also use it by placing his or her finger on the injection button 12 from the side of the injection port 121 (see FIG. 5(b)). . Thereby, in an aerosol product that is used with the injection nozzle 121 facing the user himself/herself, the user can press the injection button 12 without putting strain on the user's wrist. Note that FIG. 5(b) shows a state where the finger is placed on the injection button 12 from the right side (270° position) when facing the aerosol container 10, but this is a usage method suitable for a right-handed user. It is. A left-handed user may also place his/her finger on the ejection button 12 from the left side (90° position) when facing the aerosol container 10 .

[Embodiment 2]
The operation recess 23 in the cover cap 20 is not limited to the shape described in the first embodiment, and various other modifications are possible. In the second embodiment, some modifications of the operation recess 23 in the cover cap 20 will be described with reference to FIG. 6.

In the cover cap 20 according to the first embodiment, the angular range in which the operation recess 23 is formed includes a range of 90° to 270°. This is so that the user can put his finger on the injection button 12 from either the right side (270° position) or the left side (90° position) when facing the aerosol container 10.

However, the present invention is not limited thereto, and may be configured such that the user can put his or her finger on the injection button 12 from either the right side or the left side when facing the aerosol container 10. For example, the cover cap 20 shown in FIG. 6(a) is configured such that the angle range in which the operation recess 23 is formed includes a range of 180° to 270° (wider than the range of 180° to 270°). )are doing. In this case, the user can use the ejection button 12 not only by placing a finger on the ejection button 12 from the side opposite to the ejection port 121, but also by placing a finger on the ejection button 12 from the right side facing the injection port 121. Moreover, if the angular range in which the operation recess 23 is formed includes the range of 90° to 180° (wider than the range of 90° to 180°), it is possible to It can also be used by placing a finger on the ejection button 12 from the left side.

Further, in the cover cap 20 according to the first embodiment, the operation recess 23 is formed as one operation recess having a wide angular range. However, the present invention is not limited to this, and a plurality of operation recesses 23 may be formed. For example, the cover cap 20 shown in FIG. 6(b) has three operating recesses 23, namely, an operating recess 23a formed at an angular position of 270°, and an operating recess 23a formed at an angular position of 90°. 23b, and an operating recess 23c formed at an angle of 180°. In this case, the wall portion 24 is also provided between the operation recess 23a and the operation recess 23c, and between the operation recess 23b and the operation recess 23c.

In the cover cap 20 shown in FIG. 6(b), the user can use the injection button 12 by inserting his/her finger into the operation recess 23a or 23b and then applying the finger to the injection button 12 from the side toward the injection port 121. can. Furthermore, by inserting a finger into the operation recess 23c, the user can use the injection button 12 by placing the finger on the injection button 12 from the opposite side to the injection port 121.

When a plurality of operation recesses 23 are formed in the cover cap 20, the number of operation recesses 23 is not limited to three as shown in FIG. 6(b). For example, the operation recesses 23 may be formed at any two of the three locations shown in FIG. 6(b).

In addition, in view of the purpose of making it possible to press the injection button without putting strain on the user's wrist in an aerosol product that is used with the injection nozzle facing the user himself/herself, the operation recess 23a shown in FIG. The scope of the present invention also includes a cover cap 20 in which only one of 23b and 23b is formed.

In Embodiments 1 and 2 above, the aerosol container 10 has a two-part specification, in which two parts, namely the injection button 12 and the cover cap 20, are attached to the container body 11. However, the present invention is not limited to such a two-part aerosol container 10.

For example, in order to provide an aerosol container with a locking mechanism for the injection button, the injection button is attached to the stem of the container body, the shoulder cover is fitted directly to the top of the container body, and the shoulder cover is fitted onto the top of the shoulder cover. There are also three-part aerosol containers that include a cover cap and three parts. In a three-part aerosol container, the injection button can be locked/unlocked by relative movement (for example, rotational movement) of the cover cap with respect to the shoulder cover. The present invention is also applicable to such a three-part aerosol container.

Further, in the first and second embodiments described above, a configuration in which the injection recess 22 is provided on the front side of the cover cap 20 is illustrated, but the present invention is not limited to this. For example, as shown in FIGS. 7(a) and 7(b), the front side of the cover cap 20 is also formed into a wall portion 24, and the front side of the cover cap 20 is provided with an injection window 25 (penetrating in the front-rear direction) for exposing the injection port 121. It may also be possible to form an opening in the wall portion 24. In this way, in the cover cap 20 in which the injection window 25 is provided instead of the injection recess 22, the wall portion 24 is also present on the front side of the cover cap 20, which strengthens the prevention of malfunction when the aerosol product is not in use. can do. Furthermore, the wall portion 24 located above the injection window 25 can prevent the tip of the user's finger from reaching the injection port 121 when the user presses down the injection button 12.

In addition, in the cover cap 20, when the angular range of the operation recess 23 is formed wide so as to include a plurality of operation positions, as shown in FIGS. A plurality of guide recesses 231 (three in FIG. 7) may be formed for the fingers to be placed along. In this manner, by providing the guide recess 231 within the operation recess 23, the user's finger is supported by the guide recess 231 when the user presses down the injection button 12. This makes it difficult for the finger that presses down the ejection button 12 to shift, making it easier for the user to press the ejection button 12.

As described above, the aerosol container 10 according to the present embodiment allows the operation recess 23 of the cover cap 20 to eject water without putting strain on the user's wrist in an aerosol product that is used with the ejection port directed toward the user. It is shaped so that you can press the button. That is, the operation recess 23 is formed to include at least one angular position of 270° and 90°. In other words, the operation recess 23 allows the user to use the injection button 12 by placing a finger on the injection button 12 from the right side (270° position) or the left side (90° position) when facing the injection port 121 of the aerosol container 10. It is designed so that it is possible.

The embodiment disclosed this time is an illustrative example in all respects, and is not a basis for restrictive interpretation. Therefore, the technical scope of the present invention should not be interpreted only by the above-described embodiments, but should be defined based on the claims. Furthermore, all changes within the meaning and scope of the claims are included.
