The present technology relates to a container for containing tire repair fluid, and in particular to a container for containing tire repair fluid that, while not requiring a protective cap provided with a hole perforation member for perforating a sealing film, is capable of ensuring reliable protection effect of the sealing film during storage and allows perforating of the sealing film during tire repair.
BACKGROUNDIn recent years, when a tire mounted on a vehicle has a puncture, a tire repair fluid is injected into the tire via a tire valve to temporarily repair the puncture, and the tire is simultaneously filled with air.
Tire repair fluid injector devices (for example, see Japanese Unexamined Patent Application Publication Nos. H09-118779, 2000-108215 and 2010-69847) comprise a container for containing tire repair fluid, an air compressor, and hoses for connecting the container and the air compressor to a tire valve.
Tire repair fluid injector devices of this type are provided in vehicles in preparation for punctures. To prevent deterioration or leakage of the tire repair fluid during extended storage, a sealing film made of a material with a low gas permeability, such as an aluminum film, is adhered to an opening of the container for containing the tire repair fluid, and the container is sealed by the sealing film. Since there is a risk that the sealing film will be broken upon contact with a sharp protrusion, a protective cap is fitted to the opening of the container to protect the sealing film. Further, a perforating member for perforating the sealing film is provided at a top portion of the protective cap, and is used to perform a perforating operation of the sealing film during tire repair.
However, the protective cap provided with the perforating member has a complex form and is expensive, and reduction of the cost of the protective cap therefore is required. Also, since the protective cap provided with the hole perforating member increases the overall height of the container, reduction of this dimension is required. Note that while the above-described requirements can be met by eliminating the protective cap provided with the perforating member, if this cap is eliminated, it is not possible to ensure that protection effect of the sealing film during storage, and to perforate the sealing film during tire repair.
SUMMARYThe present technology provides a container for containing tire repair fluid that, without requiring a protective cap with a perforating member for perforating a sealing film, is capable of ensuring protection effect of the sealing film during storage and allows perforating of the sealing film during tire repair.
The present technology is a container for a tire repair fluid including a liquid containing portion for containing a tire repair fluid, an opening connected to the liquid containing portion, and a sealing film that seals the opening, the container including a plate-like protective member larger in size than an internal diameter of the opening and held in a layered state on the sealing film, wherein the protective member, upon being folded, functions as a perforating tool for perforating the sealing film.
In the present technology, the container for containing the tire repair fluid includes a plate-like protective member larger in size than an internal diameter of the opening and held in a layered state on the sealing film, wherein the protective member, upon being folded, functions as a perforating tool for perforating the sealing film. Hence, even after eliminating the protective cap provided with the hole perforating member for perforating the sealing film, the plate-like protective member makes it possible to ensure that the protection effect of the sealing film during storage. In addition, during tire repair, the user can fold the protective member and use it as a perforating tool to perforate the sealing film.
In the present technology, it is preferable that at least one folding groove extending along a surface direction of the protective member is provided in the protective member. With such an arrangement, the user can easily fold the protective member along the folding groove when using the protective member as a perforating tool. In addition, the user can easily tear the sealing film because the folded portion becomes sharp.
Further, it is preferable that at least one notch connected to the folding groove is provided in the protective member. With such an arrangement, when the protective member is folded along the folding groove, a partitioned sharp corner portion created by the notch is protruded and the sealing film can be easily broken using the corner portion.
It is preferable that the protective member is fixed to the sealing film by a shrink film that integrally covers the protective member and the opening, or that the protective member is fixed to the sealing film by an adhesive adhered to a portion of the sealing film. In such cases, the protective film can be fixed to the sealing film without adding more than necessary to the height of the container for containing tire repair fluid.
Detailed descriptions will be given below of a configuration of the present technology with reference to the accompanying drawings.
The container 1 for containing tire repair fluid includes a plate-like protective member 5 larger in size than an internal diameter of the opening 3 and held in a layered state on the sealing film 4. More specifically, the protective member 5 is fixed to the sealing film 4 by a shrink film 6 that integrally covers the protective member 5 and the opening 3. Hence, the protective member 5 is separated from the sealing film 4 by peeling the shrink film 6 from the opening 3.
The above-described protective member 5 is preferably constructed from a cardboard or resin sheet and preferably has a thickness of 1 mm to 2 mm to ensure a certain degree of stiffness. If a cardboard is used, the cardboard may have a surface coating to prevent disintegration when it is folded. The protective member 5 may, if necessary, be constructed from a metal plate. A plan view shape of the protective member 5 is not particularly limited and can, for example, be circular or polygonal shape. Since the protective member 5 has a high level of stiffness and forms a corner portion in a folded state, the protective member 5 functions effectively as a perforating tool for perforating a hole in the sealing film 4.
The above-described container 1 for containing tire repair fluid includes a plate-like protective member 5 held in a layered state on the sealing film 4.
Upon being folded, the protective member 5 functions as a perforating tool for perforating the sealing film 4. Hence, even when the protective cap provided with a perforating member of the prior art is eliminated, the plate-like protective member 5 makes it possible to ensure the protection effect of the sealing film 4 during storage. In addition, during a tire repair, a user can fold the protective member 5 and use it as a perforating tool to perforate the sealing film 4.
Here, it is necessary that the protective member 5 is larger in size than an internal diameter of the opening 3. If the protective member 5 is smaller than the internal diameter of the opening 3, there is a risk that the protective member 5 layered on the sealing film 4 will drop into the opening 3 and break the sealing film 4. Note also that in order to hold the protective member 5 in a layered state on the sealing film 4 using the shrink film 6 or the adhesive 7, the size of the protective member 5 is preferably smaller than an outer diameter of an edge surface of the opening 3.
The protective member 5 can be appropriately folded even without including the folding grooves 5a. However, the provision of at least one folding groove 5a extending along the surface direction of the protective member 5 results in a simpler folding process and a sharp folded portion, thereby allowing the sealing film 4 to be broken easily. In particular, in the case of a cardboard, it is possible to prevent a loss of shape in the paper.

When repairing a tire, a hole is first opened in the sealing film 4 that seals the opening 3 of the container 1 using the protective member 5 and the injection cap 21 is then fitted to the opening 3 in the container 1. Next, the hose 41 is connected between the outlet 22 of the cap 21 and the tire valve 13, while the hose 42 is connected between the inlet 23 of the cap 21 and the air compressor 31. A plug 32 of the air compressor 31 is then connected to a power source and the air compressor 31 is operated, thereby injecting the tire repair fluid R in the container 1 into a pneumatic tire 11 using the pressure of compressed air, and the interior of the pneumatic tire 11 remains filled with compressed air after injection is complete.
Note that while the case has been described in which the injection of the tire repair fluid R is performed with the container 1 arranged so that the opening faces upward, the arrangement of the container 1 during the injection operation can be appropriately selected in accordance with the configuration of the injection cap.
