Description

  The present invention relates to a one-push open hinge cap in which the lid does not open due to an unexpected external impact during distribution or storage, and when used, the lid opens with a one-push opening and a pouring hole is opened. is there.

  Conventionally, a so-called hinge cap, in which a lid is connected via a hinge to the back of the peripheral wall of the cap body, is connected to the mouth and neck of a plastic bottle or glass bottle that contains liquid contents. It was installed by. As the hinge, a general hinge and a snap hinge (when the lid is not fully opened or closed, the lid is automatically opened or closed automatically from that position) were used.

  However, the above-mentioned hinge caps may float or open due to unexpected external shocks during the distribution process or storage, and dust may adhere to the inside of the lid of the cap body, or the contents may leak. There was also. Further, when used, since the opening / closing knob protruding from the lower end of the front portion of the peripheral wall of the lid must be picked with a finger to open the lid, workability and handling are sometimes poor.

  The present invention solves the problems of the conventional hinge cap described above, and the lid does not open due to an unexpected external impact during the distribution process or storage. And a one-push open hinge cap that can be integrally formed.

That is, according to the first aspect of the present invention, the lid is opened and closed via a snap hinge portion comprising a central elastic bent plate having hinges at both ends and hinges on both right and left sides above the rear surface of the peripheral wall of the cap body. In the hinge cap that can be connected, the top plate of the cap body is provided with a stepped portion to which the lid is engaged, and a slide plate housing sliding contact recess groove is provided at the center of the stepped portion and the top plate so as to come out from the front to the rear. In addition, a pouring nozzle is erected substantially at the center position of the slide plate housing slide contact concave groove, and one or more pairs of slide plate lifting prevention slide contact protrusions are provided at opposite upper end positions on the left and right side surfaces. Under the front surface, the tip of the lower plate refracted to the peripheral wall side at a right angle of the L-shaped refracting push plate having an L-shaped cross section is connected, and the slide plate housing sliding contact groove of the refracting push plate for opening is substantially extended. At the upper edge of the front plate at the height above the line, Connects a slide plate that is refracted almost perpendicularly to the cap body side through the screw and is slidably received in the slide plate housing sliding contact concave groove of the cap body, and the tip reaches the elastic bending plate in the center of the snap hinge Then, at the center position of this slide plate, a flat guide hole is provided that can be slid by projecting the pouring nozzle of the cap body, and a lid push-up protrusion having a triangular cross-sectional shape is provided on the upper surface of the front position. A lock plate with a protrusion for unlocking at the tip is connected to the lower end of the vertical front plate of the refraction push plate for opening via a tearable hinge, and is opposed to the left and right sides of this lock plate. A locking plate with a locking claw on the inner surface is projected, a sealing projection is provided at a position corresponding to the cap nozzle on the bottom surface of the lid, and the cap is closed and sealed. When locking the cap, Bent vertically upward at the position of the hinge where the plate can be torn off, and lock the two locking claws projecting on both sides of the locking plate to the inner surface of the front plate of the opening push plate to open the cap Sometimes, the unlocking protrusion on the upper end of the lock plate is pulled forward to unlock the opening refraction push plate, the lock plate is torn off from the tearable hinge, and the opening refraction push plate is pushed. The slide plate is slid rearward, the lid is lifted by the lid push-up projection of the slide plate, and the elastic bending plate at the center of the snap hinge part is pushed backward by the tip of the sliding plate by the elastic force of the elastic bending plate. It is a one-push open hinge cap characterized in that after the lid is flipped up to open the lid and used, the lid is closed to the original state to seal the cap.

  A second invention of the present invention is the one-push open hinge cap according to the first invention, wherein the cap is integrally molded by an injection molding method.

  When using the one-push open hinge cap of the present invention for the first time, first put a finger on the unlocking protrusion on the upper end of the lock plate that locks the cap, pull the lock plate forward, and bend it for opening. Unlock the push plate, grab the lock plate with your fingers, twist and tear the lock plate from the tearable hinge, and push the opening refraction push plate backward with your finger. The slide plate to be connected slides backward, the lid is lifted by the lid push-up projection of the slide plate, and the tip of the slide plate pushes the elastic bending plate at the center of the snap hinge portion backward, The lid is flipped up and opened by the elastic force, and the pouring hole is opened. After use, press the top surface of the lid top with your finger and close the lid halfway forward. The lid closes to its original state by the elastic force of the elastic bending plate at the center of the snap hinge, and the spout hole Is sealed. When it is used again, the lid is opened and the dispensing hole is opened simply by pushing the opening refraction push plate backward with a finger. For this reason, workability and handleability when used are good.

  In addition, the one-push open hinge cap of the present invention is a cap that closes the lid on the cap body and seals it during distribution and storage, and the position of the hinge to which the lock plate connected to the lower end of the opening refraction push plate can be torn. Because the two lock claws that are bent vertically upward at the front and project at right angles to both sides of this lock plate are locked to the inner surface of the front plate of the unfolding push plate, the unfolding push plate is It is firmly fixed with a lock plate, and the lid will not open even if there is an unexpected external impact.

  In addition, the one-push open hinge cap of the present invention is a state in which the lid is opened horizontally with respect to the cap body in injection molding, and the open / close refracting plate, the slide plate, and the lock plate are in the vertical state. When molded with, there are few undercut parts and integral molding is possible. Since integral molding is possible, the number of molding steps is one, the cost for producing the mold is small, and the manufacturing cost is low.
