Description

[Detailed description of the invention] <Field of industrial application> The present invention relates to an overcap for a dispenser, and in particular to an overcap designed to fix a nozzle to prevent liquid from spilling out during transportation. be.

<Prior Art> Recently, as shown in FIG.
A pressurized dispenser A has been developed which dispenses the liquid from the nozzle 1 by vertically moving a head 5 and a stem 6 connected to the nozzle 1.

<Problems to be Solved by the Invention> However, the above-mentioned pressurized dispenser has a drawback in that some external force is applied to the head or the like during transportation or the like, causing the liquid inside to spill out. For this reason, a method is usually used in which the dispenser and the container body are transported separately.

<Means for solving the problem> In view of the above points, the present invention provides an overcap that can be transported even with a dispenser attached. A pressurized type having a cap with a shaped knurl, a stem slidably held on the cap, and a nozzle connected to the stem, and distributing the liquid by moving the stem and nozzle up and down. The dispenser overcap consists of a top wall and a small cylindrical wall that house the head of the dispenser, and a large cylindrical wall connected below the small cylindrical wall via a step, and the inner surface of the large cylindrical wall. Several protrusions are provided in the vertical direction, and an engaging rib is provided at the lower end of the inner surface, and a guide hole is formed in the vertical direction from the lower end of a portion of the large cylindrical wall, and a horizontal line is formed from the upper part of the guide hole. This overcap for a dispenser is characterized by having a nozzle fixing hole formed in the direction.

<Function> The dispenser overcap according to the present invention is installed by passing the nozzle of the dispenser along the guide hole. Next, the overcap is rotated to accommodate the nozzle in the nozzle fixing hole. In this state, the overcap is fixed in the vertical direction with the stepped portion engaging the upper end of the outer periphery of the cap of the dispenser and the engaging rib engaging the lower end of the outer periphery of the cap. Also, the protrusions on the inner surface of the overcap engage with the knurls of the cap and are fixed in the rotational direction. Since the nozzle is fixed in the nozzle fixing hole, the nozzle does not move in the vertical direction.

<Examples> Hereinafter, the embodiments shown in the drawings will be described in detail. FIG. 2 is a front view of the overcap B of the present invention, in which the head 5 and stem 6 of the dispenser A attached to the mouth 2 of the container body 1 are housed downward from the periphery of the top wall 11. A small cylindrical wall 12 is provided vertically, and a large cylindrical wall 14 is provided vertically below the small cylindrical wall 12 with a stepped portion 13 interposed therebetween. Here, several protrusions 15 are provided in the vertical direction on the inner surface of the large cylindrical wall 14, and an engaging rib 1 is provided on the lower end of the inner surface.
6, the protrusion 15 has a height to engage with the knurling 7 provided on the outside of the cap 3 of the dispenser A, and the distance from the engagement rib 16 to the stepped portion 13 is the same as that described above. Match the height of cap 3.

Next, a guide hole 17 is provided in the vertical direction from a part of the lower end of the large cylindrical wall 14 to the small cylindrical wall 12, and a nozzle fixing hole 18 is provided in a row from the upper part of the guide hole 17 in the lateral direction. Nozzle fixing hole 18
is an arbitrary angle (30
~90° is preferable. ).

Next, the method of using the overcap B of the present invention will be explained with reference to FIG. Fit the attachment cap 3 of Spencer A between the stepped portion 13 and engagement rib 16 of overcap B. In this state, the protrusion 15 provided on the inner surface of the large cylindrical wall 14 is engaged with the recess of the knurling 7 of the cap 3, but by molding both of them from a material such as plastic, the overcap B When rotated, the convex part of the knurling 7 becomes the protrusion 1.
5 gets over and becomes rotatable, so guide hole 1
The nozzle 4 at the top of 7 is connected to the nozzle fixing hole 18
The nozzle 4 is rotated until the side of the nozzle 4 comes into contact with the side end of the nozzle fixing hole 18. Even in this state, the protrusions 16 on the inner surface of the large cylindrical wall 14 are
Since it engages with the recess of the knurl 7 of the cap 3, it is fixed to such an extent that it will not come off due to external force during transportation.

When removing overcap B, first rotate overcap B and insert nozzle 4 into guide hole 17.
The guide hole 17 is moved to the upper part so that the nozzle 4 can pass through the guide hole 17. Then, the overcap B may be moved upward while disengaging the engagement rib 16.

When overcap B is attached, head 5, stem 6, and cap 3 of dispenser A
etc. are protected from scratches, dust, etc., and since the overcap B is engaged with the dispenser A by the engaging rib 16 and does not move in the vertical direction, no external force is applied to the head 5. Even in this case, the head 5 can be prevented from moving in the vertical direction. Further, the nozzle 3 is prevented from moving in the vertical direction by the nozzle fixing hole 18. Furthermore, since the overcap B is fixed so as not to rotate by the protrusion 15, the overcap rotates when an external force is applied, and the nozzle 3 moves into the nozzle fixing hole 18.
This prevents it from coming off and moving toward the guide hole 17 side.

<Effects> The dispenser overcap according to the present invention has the above-mentioned structure, and even if an external force is applied while the dispenser is attached to the container body, the nozzle is prevented from moving in the vertical direction, making transportation easier. This can prevent the liquid content from spilling out at times.
