Abstract

PROBLEM TO BE SOLVED: To propose a pour-out cap having a lid 7 coupled with a cap body 6 via an inverting hinge mechanism A so that it can be opened/closed, wherein a lid can be simply opened by pushing in a pushbutton 8, the lid can be easily opened only by a single hand which holds a container, reliable opening of the lid can be done, and the pour-out cap is convenient to use. SOLUTION: The pour-out cap is constituted of the pushbutton 8 of a special structure mounted so that it can be pushed in below a top plate 9 of the cap body 6, wherein its stretehable portion C elastically contracts with the pushbutton pushed in and also the front of the lid is pushed up to cause a plug protrusion 8 of the lid to remove from a pour-out port 12 of a body. Thereafter, the stretchable portion expands to cause a pressing protrusion 28 at a rear end to press a rear face of the inverting hinge mechanism to open the lid at a stroke.

Description of the Related Art As a dispensing cap, a rear upper end of a cap body and a rear lower end of a lid are connected by a pair of hinges provided at a predetermined interval, and formed between the hinges, and the upper end is covered by a lid. An inverted L-shaped plate is connected to the center of the rear wall of the body via a hinge and the lower end of the cap is connected to the center of the rear wall of the cap via a hinge. And a so-called three-point hinge, which is connected to a so-called three-point hinge, is known. In addition, these caps are configured such that a plug projection vertically provided from the back surface of the lid body is detachably fitted to an ejection hole formed in the top wall of the cap body, and a finger hook projection provided on the front surface of the cap is provided. The lid is opened by pushing up.

In addition, since it can be formed at a low cost because it can be formed by integral molding of a synthetic resin, the plug projection is generally fitted tightly into the pouring hole in order to maintain good liquid tightness. Since it requires a force when the plug projection comes off from the pouring hole, in addition to the urging force in the closing direction of the elastic plate up to the inversion boundary position at the time of opening the lid,
A relatively large force is required initially when the lid is opened.

が比較的難しい。Generally, the finger-hung projection of this type of cap is used to improve the appearance of the cap.
Alternatively, it is configured to have a small protrusion width for the reason that a normal capper can be used at the time of liquid filling so that it can be placed on an existing filling line. Therefore, there are cases where it is difficult to open the lid because the finger is not easily hooked. In addition, in the case of this type of cap, the inversion hinge mechanism does not operate in the opening direction unless the lid is opened to a position where the opening angle is relatively wide at the time of opening, so that the lid is held only with one hand holding the container. Difficult to open body.

装着した後、閉蓋して装着することができる。FIGS. 13 and 14 show an example in which a cut-out plate 33 is provided on the push button 8. The cut-out plate 33 has an arch shape extending from both sides of the pressing plate 24 of the push button 8 to the lower part of the front surface of the lid. The inner rear edges of the two leg portions are connected to the front edges of both sides via a similar cutting portion 35 so as to be cuttable. Also in this case, for example, after the push button 8 is inserted and mounted from the opening 14 in the open state, the cover can be closed and mounted.

易な開蓋が可能となる。As described above, when the front surface of the push button 8 is pressed, the expansion / contraction portion C is elastically contracted and the push-up mechanism B pushes up the front portion of the lid 7 to push out the spout 12 according to the present invention.
At this time, the force required for opening the lid is reduced at once, so that the contracted elastic portion C which has been contracted in addition to the pressing by the pressing plate is extended, and the pressing protrusion 28 at the rear portion has the elasticity of the reversing hinge mechanism A. The lower part of the plate 23 is pressed to open the lid at a stretch. Therefore, immediately after the plug projection 18 is detached from the spout 12, even if the reversing hinge mechanism A is still applying a force in the closing direction, the pressing force of the push button is small, and the push button is located at the front of the cap body. Since it is only necessary to push the container further backward, the lid can be easily opened with only one hand holding the container.

液が漏出するような不都合を生じる虞はない。The pressing plate 24 at the front end of the push button 8 is fitted so as to be able to be pushed into the opening 14 at the front of the cap body. There is no risk of inconvenience such as leakage.

作を行えるものである。Also, since the push button 8 is provided so as to be able to be pushed under the top plate 9 of the cap body 6, even if there is liquid dripping from the spout at the time of liquid pouring, there is a high possibility that the push button 8 will stop on the top plate upper surface. The opening operation can be carried out smoothly with little risk of obstructing the operation of.

止するものである。Further, in the case where the flange portion 30 for preventing deformation is integrally protruded from the annular portion 27, unnecessary bending of the annular portion 27 can be prevented as much as possible. This prevents inconvenience such as incomplete opening of the cover due to insufficient pressing force on the back surface.
