Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a top cap that is used by fitting and fixing it to the upper shoulder of the spray container, which is separated into a lid part and a fitting part, and the lid part can be used as a top cap when necessary. The fitting part relates to an improved top cap that can be used as a saucer for a spray container.

In particular, when the body of the spray container is made of metal, the bottom surface is easily scratched, which can easily cause rust and stain the mounting surface, causing various disadvantages and discomfort. □You may need to avoid placing the product on a hot surface and be careful.
There is the inconvenience of having to consider the mounting surface in advance.
In view of the above-mentioned circumstances, the present invention makes it possible to separate the annular fitting part on the lower outer periphery of the top cap from the lid part, and fixes the annular fitting part to the bottom of the body of the spray container so that it can be used as a bottom cap. A top cap that protects the bottom of the 5-pack spray container from damage, provides the convenience of being placed anywhere without considering the placement surface, and is simple and convenient to use. The purpose is to provide Hereinafter, the drawings showing the embodiments of the present invention will be explained. Figure 1 shows a packaging spray container and a top cap fitted with the lower opening of the cap fitted and fixed to the upper shoulder of the body. The top cap and the push button are shown in cross-section in a schematic side view, and Figure 2 shows a package in which the separated lid part is used as the top cap as in the past, and the fitting annular part is used as the bottom cap. The top cap is shown in cross section in a schematic side view of the spray container, and FIG. 3 is a longitudinal cross sectional view of the top cap showing the structure of another embodiment.

The top cap A is composed of a lid-like cylinder part 1, an annular fitting cylinder part 2, and a thin joint part 3 that integrally connects these two parts.

The annular fitting cylindrical portion 2 has a fitting opening 4 on the lower side.
Subsequently, a fitting recess 5 is provided in an annular shape on the inner circumferential surface of the internal cylindrical portion so that the fitting recess 5 can be forcibly fitted onto the upper shoulder 6 of the body B of the spray container and can be detachably fixed.

The thin connecting part 3 connects the inner edge of the upper end of the annular fitting cylinder part 2 and the outer periphery of the lower end of the lid-shaped cylinder part 1. They may be dispersed and connected on a ray that crosses the area.

The strength of this thin joint 3 is sufficient to prevent it from being easily separated when the top cap A is placed on the spray container during the manufacturing process or when the top cap A is used integrally without being separated. The lid-shaped cylinder part 1 closes the top surface 1a, and has a sufficient height to accommodate the push button 7 in the internal space 1b even if it becomes lower by this height when the annular fitting cylinder part 2 is separated. , as shown in FIG. 2, so that it can be used as a top cap a even after being separated.

The illustrated lid-like cylindrical portion 1 has a smaller diameter than the body B so that its lower end can be received inside the upper shoulder 6 of the body B, but the present invention is not limited to this. Further, the lid-like cylinder part 1 is not necessarily required to be used as the top cap a after being separated, and may be disposed of. When used as a top cap, the lid-shaped cylinder part 1 is provided with a locking part 8 in order to more effectively prevent it from coming off freely. As mentioned above, when the separated lid-shaped cylinder part 1 enters the groove inside the upper shoulder part 6, a certain fitting force is generated, so that it can be used as a top cap a without providing any kind of locking part 8 on the outside. Although it can be used to some extent, a locking portion 8 is provided to stabilize the attachment of the cap.

That is, as shown in FIGS. 1 and 2, the locking part 8 protrudes into the inner space 1b of the lid-shaped cylinder part 1 in a rib shape, and the push button 7 is inserted into the recess surrounded by the inner end surface 8a of the locking part. The inner end surface 8a of the locking portion is brought into contact with the outer peripheral surface of the push button 7, and this fitting force prevents the button from coming off freely. As shown in FIG. 3, a similar locking portion 9 is provided in a protruding manner on the inner periphery of the opening of the inner cylinder 10 hanging from the top surface 1a, and is fixed by engaging with the curled portion 11 at the end of the valve structure. Sometimes I do.

As shown in FIG. 2, the separated annular fitting tube 2 has a fitting opening 4
It is used by opening upward and fitting and fixing the bottom outer circumferential edge 12 of the body part B into the fitting recess 5.

Since the diameters of the upper shoulder 6 and the bottom outer peripheral edge 12 of the spray container are the same, the annular fitting tube 2 can be detachably fixed in the same manner as the top cap A in FIG. As described above, the top cap of the present invention has a thin wall that allows the annular fitting cylinder part 2, which is removably fitted and fixed to the upper shoulder part of the body of the packaging spray container, and the lid-shaped cylinder part 1, which houses the push button, to be separated. Since the joint part 3 is integrally formed, by fitting and fixing the separated annular fitting cylinder part 3 to the bottom outer peripheral edge 12 having the same shape as the upper shoulder part 6, the bottom surface of the spray container can be safely protected from damage and rust.
Moreover, it has a simple structure, can be extremely easily protected, and can be conveniently handled without any consideration for the mounting surface.
