Container of puncture repair agent

1. A container of a puncture repair agent, comprising:

a bottomed cylindrical container body to store the puncture repair agent; and

a mouth portion provided on the container body, from which the puncture repair agent is pushed out by pressing the container body,

wherein the container body is hollow molded into a flat shape and comprises a shoulder portion connected to a lower end of the mouth portion, a barrel portion connected to a lower end of the shoulder portion, and a bottom portion closing a lower end of the barrel portion,

wherein the barrel portion comprises a pair of narrow portions facing each other in a major axis direction, and a pair of wide portions facing each other in a minor axis direction,

wherein each wide portion of the pair of wide portions is provided with a pressing recessed portion having a concave curved surface shape in a side view, the pressing recessed portion capable of being elastically deformed and further recessed in a concave curved surface shape toward inside of the barrel portion,

wherein each wide portion of the pair of wide portions is set such that a wall thickness at a central portion of each wide portion of the pair of wide portions is larger than a wall thickness at both ends within the pressing recessed portion of each wide portion of the pair of wide portions in a circumferential direction orthogonal to a height direction,

wherein the wall thickness of the barrel portion gradually increases in thickness from the ends to the central portion of each of the pressing recessed portions along the circumferential direction orthogonal to the height direction, and

wherein each wide portion of the pair of wide portions is set such that the wall thickness at the central portion of each wide portion of the pair of wide portions is larger than a wall thickness at both ends within the pressing recessed portion of each wide portion of the pair of wide portions in the height direction.

2. The container according to claim 1 , wherein each wide portion of the pair of wide portions is set such that the wall thickness at the central portion of each wide portion of the pair of wide portions is 1.2 to 1.6 times of the wall thickness at both ends in the circumferential direction orthogonal to the height direction of each wide portion of the pair of wide portions.

3. The container according to claim 1 , wherein each wide portion of the pair of wide portions is set such that the wall thickness at the central portion of each wide portion of the pair of wide portions is 1.2 to 1.6 times of the wall thickness at both ends in the height direction of each wide portion of the pair of wide portions.

4. The container according to claim 1 , wherein the container body has a multi-layered structure of at least three layers comprising an inner layer, an intermediate layer and an outer layer, the intermediate layer comprising a gas barrier resin.

5. The container according to claim 4 , wherein the gas barrier resin is an ethylene-vinyl alcohol resin.

6. The container according to claim 1 , further comprising:

a seal member bonded to a top surface of the mouth portion to seal the mouth portion; and

a lead cap fitted to the mouth portion, the lead cap provided with an outlet pipe capable of leading out the puncture repair agent from the container body by breaking the sealing member when the lead cap is fitted to the mouth portion.

7. The container according to claim 1 , further comprising:

a seal member bonded to a top surface of the mouth portion to seal the mouth portion;

a protective plate detachably superposed to the seal member to protect the seal member;

a shrink film made from a heat-shrinkable synthetic resin film to cover at least the mouth portion and hold the protective plate by heat shrinking; and

a lead cap fitted to the mouth portion in a state that the shrink film is peeled off and the protective plate is removed, the lead cap provided with an outlet pipe capable of leading out the puncture repair agent from the container body by breaking the sealing member when the lead cap is fitted to the mouth portion.

8. The container according to claim 7 , wherein the shrink film is a shrink label covering an outer peripheral surface of the mouth portion and an outer peripheral surface of the container body.

9. The container according to claim 7 , wherein the shrink film is colored over a range of at least 80% or more of a back surface thereof, and has an ultraviolet transmittance less than 50%.

10. The container according to claim 1 , wherein the wall thickness of the barrel portion gradually increases in thickness from the ends to the central portion of that pressing recessed portion along the height direction within one of the pressing recessed portions in the height direction.
