Description

  The present invention relates to a storage container for a puncture repair agent, and more particularly to a storage container for a puncture repair agent in which the puncture repair agent is pushed out of the container by pressing the container.

  In recent years, puncture repair kits have been widely used in which when a tire is punctured, a puncture repair agent is injected into the tire to quickly close the puncture hole, and then the pressure of the tire is increased to a prescribed air pressure. With this puncture repair kit, a punctured tire can be repaired without replacing the tire. Conventionally, various techniques have been proposed for such a puncture repair kit (see, for example, Patent Document 1).

  The tire sealing / pump-up device described in Patent Document 1 includes an elastically deformable liquid agent bottle. This liquid bottle contains a sealing agent (puncture repair agent). When repairing a punctured tire, the liquid agent bottle is pressed and compressed to push the sealing agent out of the liquid agent bottle and injected into the tire through the supply pipe.

  FIG. 12 is a diagram showing a basic configuration of the liquid bottle of Patent Document 1. As shown in FIG. As shown in FIGS. 12A and 12B, in the liquid bottle 100, the cross section of the body 101 is formed in an elliptical shape, thereby reducing the pressing force required to push out the sealing agent 102. Is planned. That is, since the user can press the large-diameter curved portion 103 which is a wide surface of the body portion 101, the body portion 101 can be easily deformed as compared with the case where the cross section of the body portion is circular. it can.

  Patent Document 2 discloses a storage container for a puncture sealing agent in which an annular expansion / contraction portion is formed on the side wall surface of the storage container, and a flat surface is formed in a region surrounded by the expansion / contraction portion. . In this container, the flat part is expanded or contracted outward by elastic deformation of the expansion / contraction part, so that the change in the internal pressure can be alleviated even when the puncture sealant changes over time and the internal pressure increases or decreases. Yes. Further, Patent Document 2 describes a technique for increasing the rigidity of the flat surface by setting the thickness of the flat surface to 120 to 150% of the thickness of the expansion / contraction part.

  Further, Patent Document 3 discloses a container for storing and injecting a sealing agent in which a volume reducing portion having a bellows structure capable of compressive deformation is provided in a container body. In this injection container, the workability of injecting the sealing agent is enhanced by the volume reducing portion of the bellows structure, thereby suppressing the deterioration of the workability of the injection even in a low temperature environment.

  Patent Document 4 discloses a container for containing a puncture sealing agent, which is made of at least two types of thermoplastic resins and has a body portion of a container body formed by a three-layer laminate including an inner layer, an intermediate layer, and an outer layer. It is disclosed. In this container, the gas barrier property of the container is enhanced by using a gas barrier resin as the middle layer.

  By the way, from the viewpoint of improving workability of puncture repair, a technique capable of more easily injecting the puncture repair agent into the tire is required, and as a countermeasure, a storage container capable of more easily extruding the puncture repair agent is required. . In order to further enhance the extrusion performance of the container, better handling properties, squeeze properties, and recoverability are required.

  However, the liquid bottle 100 of Patent Document 1 has a configuration in which the body portion 101 is simply formed in an elliptical shape, and there is a limit to further improvement in performance in any of handling property, squeeze property, and restoration property.

  Moreover, in the storage container disclosed in Patent Document 2, the thickness of the flat surface is set to 120 to 150% of the thickness of the expansion / contraction part, thereby increasing the rigidity of the flat surface and improving the extrusion performance of the storage container. Since the expansion / contraction part and the flat surface body part are essential constituent elements, the body part shape is complicated. For this reason, there exists a problem that a shaping die becomes complicated. Therefore, a simple body shape that does not complicate the molding die is required.

  In the sealing agent storage / injection container disclosed in Patent Document 3, the container is easily crushed by the volume-reduced portion of the bellows structure, but the deformed container is difficult to return because of the bellows structure. For this reason, there exists a problem that the restoring property of a container is bad and time is required for extrusion of a sealing agent.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

  As shown in FIG. 1, a storage container 10 for a puncture repair agent according to an embodiment (hereinafter referred to as “storage container 10”) is a self-supporting bottomed cylindrical container body 20 and an upper end of the container body 20. A mouth portion 11 provided on the mouth portion 11, a sealing material (lid material) 12 for sealing the mouth portion 11, and a protective cap 13 attached to the mouth portion 11. The container body 20 and the mouth portion 11 are integrally formed of a synthetic resin. For example, injection / blow molding in which a preform molded by injection molding is heated and softened to expand, or a molten cylindrical shape It is manufactured by direct blow molding that inflates the parison.

  As shown in FIG. 2, the mouth portion 11 is formed in a substantially cylindrical shape, and a male screw portion 11 a is provided on the outer peripheral surface of the mouth portion 11. The sealing material 12 is formed in a substantially circular shape, is made of an aluminum foil or an aluminum vapor deposition film, and has a high gas barrier property. The sealing material 12 is welded to the top surface of the mouth portion 11 and seals the mouth portion 11. For welding the sealing material 12, it is desirable to use a high-frequency welding method that does not affect the portions other than the top surface of the mouth portion 11 and that can seal the sealing material 12 in a short time. When the high frequency welding method is used, the sealing material 12 is pressed against the top surface of the mouth portion 11 in a pressurized state, and the sealing surface between the mouth portion 11 and the sealing material 12 is internally heated at a high frequency for welding.

  The protective cap 13 is formed of a synthetic resin by injection molding or the like, and has an internal thread portion 13a on the inner peripheral surface. The female screw portion 13 a is screwed into the male screw portion 11 a of the mouth portion 11. The protective cap 13 is attached to the mouth portion 11 from above the sealing material 12 to protect the sealing material 12 and the mouth portion 11 when the storage container 10 is stored in a luggage compartment or the like of the vehicle. On the other hand, when repairing a punctured tire, the protective cap 13 is removed from the mouth portion 11, and a lead-out means (described later) for leading the puncture repair agent 14 from the container body portion 20 is attached to the mouth portion 11. The

The container main body 20 is filled and stored with a puncture repair agent 14 in an amount (for example, about 450 cm ³ ) determined according to the type of tire. The puncture repairing agent 14 is an optional sealing agent, and is, for example, a highly viscous liquid material having a viscosity of around 40 cps (20 ° C.) mainly composed of rubber latex.

  The container body 20 includes a shoulder portion 21, a trunk portion 22, and a bottom portion 23. The shoulder portion 21 is connected to the lower end of the mouth portion 11 and is formed so as to expand in diameter downward. The inclination angle θ of the shoulder portion 21 with respect to the direction perpendicular to the axis of the storage container 10 (the horizontal direction of the upright storage container 10) takes into account the buckling strength required for the container body 20 and the formability of the container body 20 and the like. And is arbitrarily set.

  The trunk portion 22 is continuous with the lower end of the shoulder portion 21, and is formed in a flat shape as shown in FIG. Here, the BB cross section of the trunk portion 22 is formed in a substantially rectangular shape with rounded corners. Thereby, the trunk | drum 22 is comprised by a pair of narrow part 25 which opposes a major axis direction, and a pair of wide part 26 which opposes a minor axis direction. Specifically, the narrow portion 25, the wide portion 26, and the boundary portion thereof are configured by curves having different curvatures. The dimensional ratio (D2 / D1) between the major axis D1 and the minor axis D2 in the trunk part 22 is arbitrarily set according to the gripping property of the trunk part 22, the size of the stretching ratio of the trunk part 22, and the like.

  Returning to FIG. As shown in FIG. 2, the AA longitudinal section of the body portion 22 is a basic rectangular shape, and a pressing recess 27 is provided in each of the pair of wide portions 26. The pressing concave portion 27 is formed in a concave curved surface shape when viewed from the side of the container, and is formed so as to be deepest in the vicinity of the center of the wide portion 26. The upper end position P1 of the pressing recess 27 reaches the vicinity of the lower end of the shoulder 21, and the lower end position P2 of the pressing recess 27 reaches the vicinity of the upper end of the bottom 23. As described above, the pressing recess 27 is formed to be wide over substantially the entire surface of the wide portion 26. Further, the vicinity of the pressing concave portion 27 of the shoulder portion 21 and the bottom portion 23 has a chamfered curved shape. When pressed by the user, the pressing recess 27 has a function of greatly compressing and deforming the body portion 22 while largely bending the entire wide portion 26 inward.

  Note that the radius of curvature R of the pressing recess 27 is set to an arbitrary size according to the extrusion performance required for the container body 20, the formability of the container body 20, and the like. Further, the pressing recess 27 may be configured by a curved surface formed by combining a plurality of curvature radii in addition to a curved surface formed by one curvature radius R. In this example, the cross section of the body portion 22 has a substantially rectangular shape. However, in the pressing recess according to the present invention, for example, the body portion is flattened by making the cross section of the body portion approximately elliptical. You may form and provide in the curved part of the large diameter side which opposes.

Here, the thickness distribution in the container body 20 will be described.
In order to further improve the squeeze property and the restoring property of the body portion 22, the thickness t1 (see FIG. 3) of the central portion of the wide portion 26 is made larger than the thickness t2 (see FIG. 3) of both ends in the major axis direction of the wide portion 26. It is desirable that the thickness t1 (see FIG. 2) at the center is set larger than the thickness t3 (see FIG. 2) at both ends in the height direction of the wide portion 26.

  The present inventors have advanced various research and development in order to obtain a more suitable thickness distribution. As a result, judging comprehensively including the moldability and quality of the container main body 20, in order to obtain high squeeze and restoration, the thickness t1 at the center is 1.2 of the thickness t2 at both ends in the major axis direction. It is preferable to set the size to ˜1.6 times and to set the wall thickness t1 at the center to 1.2 to 1.6 times the wall thickness t3 at both ends in the height direction. I found out. The effect of setting the wall thickness distribution will be described later.

Hereinafter, an example of a suitable thickness distribution will be described in detail based on the measurement result of the container body 20 (blow molded product). As an example of the specification of the blow molded product, the mass is 31.87 g, and the full capacity is about 483.6 cm ³ .

The thickness measurement location in the container body 20 will be described with reference to FIG.
As shown in FIG. 4 (a), the position where the thickness distribution in the height direction is measured ranges from a height of 10 mm from the bottom surface of the bottom 23 to the shoulder 21 in a total of 12 positions (measurement positions). A1-A12) were set. Further, as shown in FIG. 4 (b), the direction in which the thickness in the circumferential direction is measured is a range of 360 ° clockwise from one side (direction B1) of the parting line PL that is a dividing position of the molding die. In total, 12 directions (measurement directions B1 to B12) were set at an angle pitch of 30 °. A digital micrometer was used for measuring the wall thickness. Further, the thickness distribution in the circumferential direction was measured at a height of 60 mm (measurement position A6) from the bottom surface.

  Table 1 shows the measurement results of the wall thickness distribution in the circumferential direction, and FIG. 5 shows a graph of the measurement results of Table 1. In FIG. 5, the horizontal axis is the measurement direction (B1 to B12), and the vertical axis is the wall thickness (mm).

  As shown in Table 1 and FIG. 5, in the vicinity of the central portion of the wide portion 26 (measurement directions B4 and B10), the thickness is about 1.0 to 1.1 mm, and both ends in the major axis direction (measurement directions B2 and B6). , B8, B12) has a thickness of about 0.7 to 0.8 mm. As described above, in the thickness distribution in the circumferential direction, the thickness t1 (see FIG. 3) in the central portion is larger than the thickness t2 (see FIG. 3) at both ends in the major axis direction, and a suitable size (major axis direction). It can be seen that the thickness is 1.2 to 1.6 times the wall thickness of both ends t2.

  Next, the measurement result of the thickness distribution in the height direction is shown in Table 2, and a graph of the measurement result in Table 2 is shown in FIG. In FIG. 6, the horizontal axis is the thickness (mm), and the vertical axis is the measurement position (A1 to A12).

  As shown in Table 2 and FIG. 6, in the vicinity of the central portion of the wide portion 26 (measurement positions A6 to A8 in the measurement directions B4 and B10), the thickness is around 1 mm, and both end portions in the height direction (measurement directions A2 and A11). ), The wall thickness is around 0.8 mm. Thus, in the thickness distribution in the height direction, the thickness t1 (see FIG. 3) at the center is larger than the thickness t3 (see FIG. 2) at both ends in the height direction, and a suitable size ( It can be seen that the thickness is 1.2 to 1.6 times the wall thickness t3 at both ends in the height direction.

Next, the material and layer structure of the container body 20 will be described.
The container body 20 is made of any synthetic resin material. However, when the puncture repair agent 14 is stored for a long period (for example, five years), the puncture repair agent 14 is prevented from being deteriorated, altered, or corroded by oxygen, or reduced in water vapor, ammonia, etc. in the puncture repair agent 14. In order to suppress this, it is necessary to impart high storage performance to the container body 20. In order to impart high storage performance to the container body 20, it is effective to configure the container body 20 with a multilayer structure including a material having a high gas barrier property and to keep the gas permeability of the container body 20 low.

  For example, the container main body 20 is composed of a multilayer structure including at least three layers including an inner layer, an intermediate layer, and an outer layer, and the intermediate layer is composed of a gas barrier resin. As this gas barrier resin, an ethylene / vinyl alcohol resin (EVOH) that can obtain a high gas barrier property even if it is thin is suitable. The material of the inner layer and the outer layer that sandwich the intermediate layer can be selected from any synthetic resin such as polyethylene, polypropylene, and polyester. The container body 20 having such a multilayer structure can be obtained by, for example, blow molding using a multilayer parison.

An example of the multilayer structure of the container body 20 will be described with reference to FIG.
As shown in FIG. 7, this multi-layer structure is a laminate of 4 types and 6 layers composed of 6 layers and consisting of 4 types of materials. Here, from the inner side (the puncture repair agent 14 side), a first layer 20a made of low-density polyethylene, a second layer 20b made of an adhesive layer, a third layer 20c made of EVOH, a fourth layer 20d made of an adhesive layer, recycled A fifth layer 20e made of a material and a sixth layer 20f made of low-density polyethylene are sequentially laminated. Note that an unnecessary portion (so-called burr) cut out from the molded product can be used as the recycled material of the fifth layer 20e.

  Table 3 shows an example of the thickness and the composition ratio of each layer having such a multilayer structure. In the table, the parentheses indicate the composition ratio of each layer.

  As shown in Table 3, by forming the first and sixth layers made of low-density polyethylene and the fifth layer made of recycled material thick, the moldability and rigidity of the container body 20 (see FIG. 2) are secured. . On the other hand, the third layer is formed thin by using EVOH which is excellent in gas barrier property even if it is thin. As a result, a high gas barrier property is imparted to the container body 20 to prevent the puncture repair agent 14 from being deteriorated, altered, or corroded, and to suppress a decrease in water vapor, ammonia, or the like in the puncture repair agent 14, and the third layer. By forming a thin film, the mass and material cost of the container body 20 can be kept low. Further, by using a recycled material for the fifth layer, it is possible to reduce the environmental load and further reduce the cost.

  In the embodiment, the gas permeability of the container body 20 is kept low by the multilayer structure including the gas barrier resin, but in addition to this, the surface (for example, the inner surface) of the container body 20 has aluminum or an aluminum alloy, It is also effective to evaporate a thin film layer made of alumina, silica, or the like and enhance the gas barrier property of the container body 20 by using the deposited film.

  A method for repairing a punctured tire using the storage container 10 described above will be described with reference to FIGS. As shown in FIG. 8A, the derivation means 32 is used for repairing a puncture. The derivation means 32 includes a fitting portion 33 that can be fitted into the mouth portion 11, and a lead-out pipe 35 that penetrates the center of the fitting portion 33. The fitting portion 33 has a female screw portion 33 a that is screwed into the male screw portion 11 a of the mouth portion 11. An injection hose 36 is connected to the downstream end of the outlet pipe 35.

  First, the user removes the protective cap 13 from the mouth portion 11, and instead screwes the fitting portion 33 into the mouth portion 11 and attaches the derivation means 32 to the container body portion 20. At this time, the sealing material 12 is broken by the tip of the outlet pipe 35 inserted into the mouth portion 11 as shown in FIG. Thereby, the inside and the outside of the container main body 20 communicate with each other through the outlet pipe 35. Further, since the top surface of the mouth portion 11 is sealed by the fitting portion 33, there is no fear that the puncture repair agent leaks in the vicinity of the mouth portion 11.

  Next, as shown in FIG. 9 (a), after connecting the downstream end of the injection hose 36 to the valve 31a of the punctured tire 31, the container body 20 is inverted and a pair of pressings is applied. The recess 27 is gripped. And as shown in FIG.9 (b), a pair of press recessed part 27 is pressed so that the container main-body part 20 may be compressed. Then, as shown in FIG.9 (c), a pair of wide part 26 will be elastically deformed so that it may mutually approach, and the container main-body part 20 is compressed. As a result, an amount of the puncture repair agent 14 corresponding to the volume change of the container body 20 to be compressed is pushed out from the outlet pipe 35. The extruded puncture repair agent 14 is injected into the tire 31 via the injection hose 36.

  When the user loosens his / her hand, the pair of wide portions 26 which are greatly elastically deformed are released from the pressing force and quickly restored to the original form. In this way, the amount of decrease in the internal volume is large, and the puncture repair agent 14 can be injected into the tire 31 in a short time by performing the pumping operation of the container main body 20 to be quickly restored a plurality of times.

  Next, as shown in FIG. 10, the compressor 38 is connected to the valve 31a of the tire 31 via the pressure hose 37, and the power plug 41 of the compressor 38 is inserted into the power socket of the vehicle. Then, the compressor 38 is operated to increase the pressure of the tire 31. After the pressure of the tire 31 is increased to a prescribed air pressure, the pressure hose 37 and the compressor 38 are removed from the tire 31 and the vehicle is preliminarily traveled. When the preliminary traveling is finished, the air pressure of the tire 31 is measured, and if necessary, the pressure of the tire 31 is increased again to a prescribed air pressure by the compressor 38. Thus, the puncture repair of the tire 31 is completed.

The effect of the storage container 10 of the embodiment described above will be described.
In the present embodiment, the body portion 22 of the container body 20 is formed into a flat shape, and a pair of pressing recesses 27 are provided in the pair of wide portions 26 so that the user can grip and press the pressing recesses 27. I did it.

  In contrast, as shown in FIG. 11A, in the conventional liquid medicine bottle 100, the body portion 101 is formed in an elliptical shape, and the user presses the large-diameter curved portion 103. In this case, since the large-diameter curved portion 103 is a simple convex curved surface, handling properties are poor. Further, since the large-diameter curved portion 103 is convexly curved, as shown in FIG. 11B, the pressing force of the user locally acts on the large-diameter curved portion 103, and the liquid bottle The amount of decrease in the internal volume of 100 is small. That is, the squeeze property is poor and the liquid bottle 100 must be pumped many times in order to push out all the sealing agent 102. In addition, since the pressing force of the user acts locally, the large-diameter curved portion 103 is deformed so as to be depressed, and the recoverability is poor.

  In this respect, in the present embodiment, as shown in FIGS. 9A and 9B, the concave curved pressing concave portion 27 can be gripped and pressed, so that the user's hand is placed on the pressing concave portion 27. Fits well and handling becomes much better. In addition, since the pressing concave portion 27 has a concave curved surface shape and is formed to extend over substantially the entire surface of the wide portion 26, the pressing force acts on the entire wide portion 26. As a result, as shown in FIG. 9C, since the entire wide portion 26 is greatly elastically deformed, the amount of decrease in the internal volume of the container main body portion 20 is large. As a result, excellent squeeze properties can be obtained. In addition, since the entire wide portion 26 is greatly elastically deformed, the wide portion 26 is easy to return to its original form, and is excellent in resilience.

  In addition, in the wide portion 26, the thickness t1 (see FIG. 3) at the center is set larger than the thickness t2 (see FIG. 3) at both ends in the major axis direction, and the thickness t1 (see FIG. 3) at the center is set. Was set larger than the thickness t3 (see FIG. 2) at both ends in the height direction. As a result, the central portion of the pressing recess 27 becomes thicker and the corners around the pressing recess 27 become thinner. Since the rigidity of the central portion of the pressing recess 27 is increased by increasing the thickness of the central portion of the pressing recess 27, the user can easily press the pressing recess 27. On the other hand, in the corners around the pressing recess 27, the rigidity is lowered, so that it is easily deformed and restored. As a result, the squeeze property and the restoring property of the body portion 22 can be significantly improved.

  Therefore, according to this embodiment, it is excellent in handling property, squeeze property, and restoration property, and it is possible to more easily extrude the puncture repair agent 14 with a simple body shape that only forms the pressing recess 24. A container 10 is provided.

  Furthermore, in this embodiment, the sealing material 12 made of aluminum foil or an aluminum vapor deposition film is welded to the top surface of the mouth portion 11, and the sealing material 12 is broken by the lead-out pipe 35.

  On the other hand, conventionally, a lid structure is known in which an inner plug made of a synthetic resin is fitted into the mouth portion, and when the puncture is corrected, the bottom portion of the inner plug is broken by a lead-out pipe. In the case of such a lid structure, in addition to the high cost of the lid member (inner plug), it is necessary to break the hard bottom of the inner plug, so the workability is also poor.

  In this respect, in the present embodiment, since the mouth portion 11 is closed with the sealing material 12, the component cost of the lid material is reduced. Further, since the thin sealing material 12 can be easily broken by the outlet pipe 35, workability is also good.

  As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiments. Further, it is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
