Abstract

<P>PROBLEM TO BE SOLVED: To provide an easy-to-separate removable cap designed so that when the cap is separated and detached from a container by a separation handle, force can easily be applied to the cap without rotating the cap, and an over-cap can be fitted over the cap. <P>SOLUTION: The cap of a cap striking system includes: a discharging opening extending upright from the top plate of a cap body and covered by a lid; a ring formed on the internal face of a circumferential wall so as to engage with the container. In the cap, a separation- handle locking projection is formed on a specific part of the outer face of the circumferential wall. The separation handle the locking hole of which locks on the separation-handle locking projection is detachably connected to the lower end of the outer face of the circumferential wall and below the locking projection via a hinge. Two opposite thin weak lines are formed toward the upper end of the circumferential wall from both left and right end positions of the hinge on the outer peripheral face of the circumferential wall so as to separate farther from each other upward. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  TECHNICAL FIELD The present invention relates to a cap that can be easily separated and removed from a container after it is attached to a mouth of a container by a stopper method and used.

Conventionally, a large number of cap-type caps have been used at the mouth of containers in a wide range of fields such as food because of the ease of high-speed filling and sealing. After using these caps, they were collected separately from the container for resource reuse or disposal. For this reason, many caps that can be easily separated and collected from the container have been invented and devised. For example, a cap-type one-piece cap whose lid is connected to the cap body via a hinge. A circumferential separation knob is projected from the upper end portion adjacent to the hinge of the peripheral wall of the cap body. A linear thin fragile portion in the circumferential direction is provided for a predetermined length from the position near the front upper end to the upper end portion of the peripheral wall, and a linear thin fragile portion is provided with a forward inclination from the front lower end position of the sorting knob to the lower end on the peripheral wall. After use, when separating the cap from the container, the separation knob is pulled forward in the circumferential direction to break the two linear thin fragile portions and further pull the broken portion upward. Then, the cap was detached from the container (see, for example, Patent Document 1).
JP-A-9-58716

  However, the above-described conventional stopper-type separation / detachment cap has a circumferential separation knob protruding from the upper end portion adjacent to the hinge of the peripheral wall of the cap body. It was not suitable as a cap that protrudes from the overall silhouette and wears an overcap. In addition, when the separation knob is pulled forward in the circumferential direction to break the two linear thin fragile portions, the cap may rotate and force may be difficult to enter.

  The present invention solves the problems of the above-described conventional stoppering type separation and removal cap, and when the separation and separation of the cap from the container with the separation knob, the cap does not rotate and force is easily applied, In addition, the present invention provides a cap that can be easily separated and separated, over which an overcap can be worn.

  That is, the first invention of the present invention is a cap-type cap that has a spout portion to be attached to the lid portion on the top plate of the cap body and has an occlusal ring with the container on the inner peripheral surface of the peripheral wall. A separation knob locking projection protruding from a predetermined position on the outer peripheral surface of the peripheral wall, and a separation knob that removably locks the locking hole in the separation knob locking protrusion. Two linear thin-walled weaknesses that are connected to the lower outer peripheral surface lower end of the sorting knob locking projection of the first through a hinge portion and reach the upper end of the peripheral wall from the left and right end positions of the hinge portion of the peripheral wall outer peripheral surface The separation knob is provided to be opposed to each other by opening upward, and the separation knob is normally locked to the separation knob locking projection, and when the cap is separated from the container, the separation knob is connected to the separation knob engagement. Removed from the stop protrusion and pulled upward, provided on the peripheral wall Serial by breaking the linear thin fragile portion of the two, it is readily separated removable cap, characterized by leaving the cap from the container.

Next, according to a second aspect of the present invention, the shape of the sorting knob is U-shaped and has a locking hole at a central position, and the left and right upper ends of the U-shaped sorting knob are connected to the peripheral wall. 2. The easily separable cap according to claim 1, wherein the cap is connected to a lower end of a lower outer peripheral surface of the separation knob locking projection via a hinge portion. 3.

  And the 3rd invention of the present invention is a cap-type cap having a spout portion to be installed on the top of the cap body and having an occlusal ring with the container on the inner peripheral surface of the peripheral wall. The separation annular knob is attached to the outside of the lower end portion of the peripheral wall, and a pair of non-breakable connecting portions at a predetermined position and a plurality of easily breakable small connecting portions are radially bridged at other positions, Two linear thin fragile portions that reach the upper end of the peripheral wall from the left and right end positions of the pair of non-breakable connections connected to the peripheral wall are provided to face each other by opening upward, and when the cap is separated from the container, The opposing side of the pair of non-breakable connecting portions of the separation annular knob is pulled upward to break the plurality of easily breakable small connecting portions, and further, the two linear thin-walled weak portions provided on the peripheral wall Break the cap and remove the cap from the container It is readily separated removable cap which is characterized.

  The caps that can be easily separated and separated according to the first and second aspects of the present invention are the two caps provided on the peripheral wall when the caps are separated from the container, and the separating knobs are removed from the separating knob engaging projections and pulled upward. The caps are separated and removed from the container by breaking the linear thin-walled fragile portion of the cap, and the detachment operation pulls upwards, making it easy to apply force and rotating the cap without applying force in the circumferential direction. Therefore, the force can be used effectively, and as a result, the cap is easily detached from the container.

  Further, the easily separable cap according to the third aspect of the present invention is configured such that when separating the cap from the container, the opposing sides of the pair of non-breakable connecting portions of the separation annular knob are lifted upward to form a plurality of easily breakable small caps. Breaking the connecting part, further breaking the two linear thin fragile parts provided on the peripheral wall, separating and separating the cap from the container, the detaching operation is to lift upward and easy to apply force, Further, since no force is applied in the circumferential direction and the cap does not rotate, the force can be used effectively. As a result, the cap is easily detached from the container.

  Further, the easily separable cap separating knob of the first or second invention and the easily separable cap separating annular knob of the third invention are attached compactly with a sense of unity in the cap body. Therefore, it is easy to attach the overcap to the cap attached to the mouth and neck of the container.
