Injection nozzle

Abstract

To provide an injection nozzle capable of spraying a cooling agent to a sole while wearing a shoe.SOLUTION: An elongated hollow flexible tube is closed at one end, and is equipped with a flat-shaped guide portion that guides from a top edge to a space between an insole and a sole of a shoe. The hollow tube is released at the other end, and is connected to an injection port of a spray container. An injection nozzle is provided with a through-hole penetrating from an inner wall to the outer wall of the tube, near the one end of the hollow tube.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to an injection nozzle that can spray onto the sole while wearing shoes.

Background Art

[0002] It is known that performance is improved when a coolant or the like is sprayed during sports. Such a coolant is sprayed onto the sole after taking off the shoes. Therefore, there is a problem that it takes time to spray.

[0003] Devices have been developed that can send cold air to the feet while wearing shoes (see, for example, Patent Document 1). However, since this device is attached to the shoes, it has problems such as a complicated structure, inability to withstand hard use such as sports, restrictions on the weight and structure of the shoes, and the need to attach it to each shoe.

Summary of the Invention

Problems to be Solved by the Invention

[0005] An object of the present invention is to provide an injection nozzle that can spray a coolant or the like onto the sole while wearing shoes.

Means for Solving the Problems

[0006] The injection nozzle of the present invention is an elongated hollow flexible tube, one end of the hollow tube is closed, and a flat guide portion is provided at its tip to guide from the top edge of the shoe between the insole and the sole. The other end of the hollow tube is open and configured to be connected to the injection port of the spray container. Near one end of the hollow tube, a through hole penetrating from the inner wall to the outer wall of the tube is provided.

[0007] The injection nozzle of the present invention is provided with a flat guide portion that guides from the top edge of the shoe between the insole and the sole. As a result, while wearing the shoes, the flat guide portion can be guided to the sole, and the contents can be sprayed from the spray container.

[0008] Also, since the other end of the tube is open and configured to be connected to the injection port of the spray container, it can be used instead of the injection nozzle of a commercially available spray container containing a coolant or the like.

[0009] Also, it is preferable that the injection nozzle of the present invention has two or more through holes. If there are two or more, the coolant or the like can be sprayed before and after the sole, so the effect can be enhanced.

[0010] Also, it is preferable that the injection nozzle of the present invention is provided with two ribs symmetrically along the longitudinal direction of the outer wall of the tube. By providing the ribs, it is possible to prevent the tip of the injection nozzle from bending sideways and more reliably guide it from the top edge of the shoe between the insole and the sole.

Effect of the Invention

[0011] The injection nozzle of the present invention can guide the portion with the through hole to the sole while wearing the shoes, so the contents can be sprayed from the spray container.

Mode for Carrying Out the Invention

Examples

[0013] FIG. 1 is a plan view showing the injection nozzle of the present invention, and FIG. 2 is a side view showing the injection nozzle of the present invention. The injection nozzle 1 of the present invention includes an elongated hollow flexible tube 2 and a guide portion 3. The material of the guide portion 3 is also made of the same material as the tube 2 and is flexible.

[0014] One end 4 of the elongated hollow flexible tube 2 is closed, and a guide portion 3 is provided at its tip. The guide portion 3 guides the injection nozzle 1 of the present invention between the insole of the shoe and the sole of the foot. As shown in FIGS. 1 and 2, the guide portion 3 has a flat shape. If it has a flat shape, it is easy to insert it into the top edge of the shoe. When the tip of the guide portion 3 reaches the insole of the shoe, it can bend and proceed between the insole of the shoe and the sole of the foot. If the guide portion 3 has a flat shape, there is no particular limitation, but a shape without corners such as a substantially circular shape or a substantially elliptical shape is preferable because it does not hurt the foot.

[0015] The other end 5 of the tube 2 is open. It is configured to be connected to the injection port of the spray container through this opening.

[0016] Near one end 4 of the hollow tube 2, there is a through-hole 6 that penetrates from the inner wall to the outer wall of the tube 2. A coolant or the like is sprayed onto the sole through the through-hole. The through-hole 6 may be provided at a position where the coolant or the like can be sprayed before and after the sole between the insole and the sole. The number of the through-holes 6 is not particularly limited as long as the coolant or the like can be appropriately sprayed, but it is preferably two or more, and more preferably two. Further, the position of the through-hole is preferably provided opposite to the tube 2 and substantially parallel to the flat surface of the guide portion 3 as shown in FIG. 2.

[0017] The injection nozzle 1 of the present invention may be formed of a flexible material, particularly plastic. The degree of flexibility is required to be such that the injection nozzle 1 is not damaged when it is bent at an angle of about 90° when inserted between the top edge of the shoe and the insole and the sole. Further, when bent at an angle of about 90° and between the insole and the sole, a hardness is required such that the tube 2 is not crushed and the coolant or the like cannot pass through. Examples of such a flexible material include, but are not limited to, polypropylene.

Example

[0018] Further, as another form of the injection nozzle 1 of the present invention, as shown in FIG. 3, two ribs 7 are symmetrically provided along the longitudinal direction of the outer wall of the tube 2. By providing the ribs, the tube can be prevented from bending sideways.

[0019] The injection nozzle 1 of the present invention can be manufactured using a known method such as injection molding.

[0020] (Method of using the injection nozzle) The injection nozzle 1 of the present invention is applied to a spray container filled with a drug such as a coolant, an anti-inflammatory agent, and an analgesic. The injection nozzle 1 of the present invention is connected to the injection port of the spray container.

[0021] First, as shown in Fig. 4, insert the guide part 3 from the top edge of the sole side of the shoe. When continuously pushing the tube 2, the guide part 3 abuts against the insole. When continuously pushing the tube 2 further, the tube 2 and the guide part 3 bend, and the guide part 3 advances between the insole and the sole of the foot. For example, as shown in Fig. 5, when the guide part 3 exceeds the instep part, by pressing the injection port, the medicine is sprayed onto the sole of the foot. After spraying, pull the tube 2 and remove the injection nozzle 1. Remove the used injection nozzle 1 from the injection port of the spray container.
