Abstract

Cap unit provided with: cap body ( 7 ) having first-flow-channel ( 5 ) for feeding compressed air from compressor ( 3 ) into bottle container ( 4 ) and second-flow-channel ( 6 ) for sequentially providing puncture repair liquid (T) and compressed air from the bottle container; and first and second closing plugs ( 8 A, 8 B) independent from one another and closing both flow channels. Cap body ( 7 ) includes boss portion ( 11 ) on which is disposed first-closing-plug securing portion ( 11 A) permitting elastic fitting of first-closing-plug disposed. Upper opening portion ( 5 a ) of first-flow-channel opens further inward than the first-closing-plug securing portion, and the upper opening portion of second-flow-channel opens further outward than the first-closing-plug securing portion. Second-closing-plug can be moved by hand and opens second-flow-channel by means of said movement. This reduces precision requirements when fitting a cap unit while ensuring the opening and closing of a first and second path.

First claim

The invention claimed is:

1. A cap unit for puncture repair, the cap unit comprising:
a cap body attached to a mouth portion of a bottle container storing a puncture repair liquid, and comprising an inlet mouth portion configured to feed compressed air from a compressor into the bottle container through a first flow channel, and an outlet mouth portion configured to sequentially take out the puncture repair liquid and the compressed air from the bottle container through a second flow channel by a feed of the compressed air, wherein the second flow channel comprises a second vertical flow channel portion extending downward from the upper opening portion, and a second lateral flow channel portion communicating via an intersection portion P 2 with the second vertical flow channel portion, the second lateral flow channel portion extending from the intersection portion P 2 to a tip opening portion of the outlet mouth portion; and
closing means for closing the first flow channel and the second flow channel, wherein the closing means comprises a first closing plug configured to close the first flow channel, and a second closing plug defined independently of the first closing plug and configured to close the second flow channel, wherein the second closing plug is configured to be interposed in the second lateral flow channel portion so as to close the second lateral flow channel portion, and the second closing plug is configured to be manually moved along the second lateral flow channel portion so as to open the second lateral flow channel portion,
wherein the cap body comprises a mouth portion securing recess configured to allow the mouth portion of the bottle container to be inserted into and secured to the mouth portion securing recess, and a boss portion extending upward from a bottom surface of the mouth portion securing recess, and comprising a first closing plug securing portion permitting elastic fitting of the first closing plug to the first closing plug securing portion,
wherein an upper opening portion of the first flow channel opens further inward than the first closing plug securing portion of the boss portion, and an upper opening portion of the second flow channel opens further outward than the first closing plug securing portion,
wherein the first closing plug is configured to disengage from the first closing plug securing portion to open the first flow channel upon an increase in pressure of the first flow channel with the compressed air from the compressor, and the second closing plug is subjected to a manual movement so as to open the second flow channel by the movement, and
wherein a hose coupling cylinder is disposed on the outlet mouth portion, an inner end side of the hose coupling cylinder being slidably inserted into the second lateral flow channel portion, the hose coupling cylinder comprising a hose coupling portion defined on an outer end side of the hose coupling cylinder, and wherein, upon a push force applied when inserting the hose into the hose coupling portion, the second closing plug is configured to move inward together with the hose coupling cylinder so as to open the second lateral flow channel portion.

2. The cap unit for puncture repair according to claim 1 , wherein the upper opening portion of the first flow channel is located higher than a liquid surface of the puncture repair liquid stored in the bottle container in a mount state in which the bottle container is mounted on the cap unit.

3. The cap unit for puncture repair according to claim 1 , wherein the upper opening portion of the second flow channel communicates with the bottom surface of the mouth portion securing recess.
