Description

  The present invention relates to a liquid leakage prevention clip for a paper pack, which is prepared by appropriately drinking the stored drinking water as desired, sealing the opening, and preparing for subsequent drinking.

Conventionally, for example, the following Patent Document 1 exists to seal the opening portion of the seed paper pack.
In other words, according to this Patent Document 1, the cap with opening handle is screwed into the cap after opening, and is thus molded and integrated with a synthetic resin different from the paper pack.
Therefore, the manufacturing is troublesome, and it is also disposed of separately from the paper pack.
Similarly, in Patent Document 2, a chuck formed of a synthetic resin different from the paper pack is integrated, which is not preferable in manufacturing.
In view of these problems, it cannot be denied that Patent Document 3 exists.
That is, the opening portion of the paper pack is sandwiched between the two-pronged clips formed of synthetic resin.
However, this Patent Document 3 discloses a cap part that simply covers the entire opening of a paper pack that is opened and seals it, and a handle and a paper pack that are formed by hanging from the base end of the cap part at a right angle. The cylindrical main body (holder) to be mounted is integrally formed so as to be detachably coupled to the body portion of the body, and naturally there are problems in manufacturing due to the complicated structure.
In particular, since the opening is covered over the entire length of the cap portion, for example, the cap portion cannot be covered with a drinking straw inserted into the opening portion, which is inconvenient when taking a walk in a sightseeing spot or the like.

  After opening the paper pack, with the trouble of manufacturing by screwing the cap to be temporarily sealed, the problem of discarding separately from the paper pack, and the opening is covered with the cap part over the entire length The cap part cannot be covered with the drinking straw inserted in the opening, which is inconvenient when taking a walk in sightseeing spots.

The present invention sandwiches the left and right opening edge pieces with the opening portion of the paper pack open, and sandwiches the left and right opening edge pieces of the paper pack in the liquid leakage prevention clip of the closing paper pack. The clip main body composed of the left and right clamping pieces and the hand holding piece that connects and integrates the upper end edges of the left and right clamping pieces is integrally formed of synthetic resin.
Furthermore, the present invention is characterized in that the right and left clamping pieces are integrally formed with protrusions that are in pressure contact with each other on the inner side surfaces and over the entire edge of the opening edge piece of the paper pack.
Further, the present invention is characterized in that the protrusions of the opening edge piece are a plurality of protrusions independent in the same direction.
Further, the present invention is characterized in that the holding piece of the hand is used as a space for attaching a display sheet such as a name, a memo, and an advertisement.

(1) According to claim 1, after drinking the drinking water as needed, the opening edge piece is sandwiched between the left and right clamping pieces of the clip body, thereby preventing the liquid leakage of the paper pack, and The pinch is held at a certain distance (interval) from the opening by picking the holding piece with the hand, so that the hand does not touch the drinking water adhering to the vicinity of the opening and the hand becomes dirty. There is nothing.
Further, there is no need for a threaded opening formed with a synthetic resin different from that of the paper pack, and further a chuck or the like.
In addition, after opening the paper pack, the left and right clamping pieces of the clip body can be slid in the horizontal direction, so the opening width of the paper pack can be adjusted arbitrarily, and the drinking straw is inserted into the opening more than necessary. There is no opening and no foreign matter is mixed.

(2) According to the second aspect, since the opening edge piece of the paper pack is locally pressed by the protrusion over the entire edge, it is held by the elasticity having the gentle pressure action of the entire left and right holding pieces. Compared to the above, the sealing property is rich.

(3) According to claim 4, it can be used as an advertisement display sheet particularly in a sightseeing spot or a drinking water manufacturer, and is linked to the PR effect of the sightseeing spot.
In addition, the owner can be identified by displaying the name, can be distinguished from others, and can be used as a memo when a phone call is made while walking, which is extremely effective.
