Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap having an opening/closing lid pivotally attached to the top of the cap main body and having a stopper inserted into a spout hole in the top.

"Prior art" According to this type of cap, when dispensing the liquid content,
Since it is not necessary to remove the cap from the container each time, it is widely used for squeeze-shaped shampoo containers.

In conventional caps of this kind, the opening/closing lid with a stopper must be able to maintain an open state when the cap is opened, and for this reason, the cap is pivoted using a well-known three-point hinge, a snap hinge, or the like.

``Problems to be solved by the invention'' If the hinge is a three-point hinge or a snap hinge, the cap body, hinge, and opening/closing lid are integrated, so the mold becomes complicated when molding synthetic resin materials, and it is difficult to use these hinges. In this case, in order to obtain the hinge effect that allows the lid to remain open, it is necessary to manually open the lid to an almost upright position. It's difficult.

The purpose of this invention is to provide a convenient cap that can simplify the mold and can be operated with one hand.

"Means for Solving the Problems" The cap of the present invention has a spout hole 5 in the top wall 4, an external peripheral wall 7 around the mounting peripheral wall 6, and a part of the front side of the external peripheral wall 7. A cap body 1 is recessed, a push-in plate 9 is set upright in the recessed part 8, and an engaging protrusion 10 of one side of the stopper is protruded from the upper part of the front side.
A protrusion-shaped stopper 11 that is inserted into the spout hole 5 from the back side is provided vertically, and the rear end is pivotally connected with a hinge 12 and is disposed on the top surface of the cap main body 1, and the push-in plate 9 The opening/closing lid 2 has a front lower surface in contact with the upper end formed into an engaging slope A diagonally backward and downward, and has the other engaging protrusion 13 of the stopper provided on the front part thereof, and the opening/closing lid 2 is mounted on the hinge 12. and a drive spring 3 that always biases the opening/closing lid 2 in the opening direction.

"Function" In the above, normally, as shown in FIG. 13 is engaged, the stopper is locked, and the opening/closing lid 2 is kept in the closed state.

If you want to open the cap or lid from this state, please use the container body 1.
4, hold the body 15 with one hand, place the thumb of this hand, for example, on the front surface of the push plate 9, and push the push plate 9. Then, the upper part of the push-in plate 9 slides along the engagement slope A, and this slide opens the opening/closing lid 2.
As the front part is pushed up, the clasp is unlocked and the stopper 1
1 is removed from the pouring hole 5, and therefore, after this, the drive spring 3 opens the opening/closing lid 2 rearward. That is, the opening/closing lid 2 is opened with one touch by pushing the push-in plate 9 a short distance.

``Embodiment'' The cap of the present invention includes a cap main body 1 that is attached to the mouth and neck of a container body 14, an opening/closing lid 2 that is pivotally attached to the upper surface of the main body 1 with a hinge 12 and locked with a clasp, and The drive spring 3 is mounted on the hinge 12 and always biases the opening/closing lid 2 in the opening direction.

The cap body 1 has a mounting peripheral wall 6 shaped like a round tube,
The external peripheral wall 7 is formed into a rectangular cylindrical shape to match the shape of the container body 14, and is attached by pushing the mounting peripheral wall 6 into the mouth and neck of the container body 14. At this time, the vertical ring 16 provided inside the peripheral wall 6 is attached to the mouth and neck. The rear top portion of the outer circumferential wall 7 is concave and serves as a hinge 12 mounting portion. Further, the rear surface of the upper end of the pushing plate 9 is cut diagonally, and engagement protrusions 10, 10 for locking metals are provided at the corners of the front upper surface on both sides of the pushing plate 9.

The opening/closing lid 2 has a shallow rectangular dish-like shape, and the engagement slope A is formed on the lower surface of the front hanging wall 17, and the other engagement plate of the stopper is formed on the back of the corner of the hanging wall 17 on both sides of the engagement slope I. Coupling protrusions 13, 13 are provided. The hinge 12 is
The structure is such that the hinge boss 12a is fitted into the concave portion, and the hinge boss 12a is pivoted to a fixed portion on the cap body 1 side with a pin 12b.

As the drive spring 3, a well-known spring with mustaches is used. That is, a coiled spring body 3a is mounted on a hinge pin 12b, and one of the hairs 3b of the other part is applied to the fixed side and the other hair 3c is applied to the movable side, so that the spring force is always applied to the movable side, that is, the opening/closing lid 2. It is installed so that it acts as a force for opening the lid.

Each of the above parts, except for the drive spring 3, is made of synthetic resin material.

"Effect of the invention" As mentioned above, according to the invention, the cap body 1
Since the opening/closing lid 2 and the opening/closing lid 2 are made as separate members, there are only two simple molding molds, which simplifies the processing. Further, a drive spring 3 for opening and closing is provided on the hinge 12 of the opening and closing lid 2, and a stopper for locking the opening and closing cover 2 is provided on the front part, and when this stopper is unlocked by pushing the push plate 9, the drive spring 3 opens the cover. This makes it possible to open the bottle and lid with one hand while holding the bottle, making it convenient for use. Furthermore, since the pushing plate 9 is pushed in through the engagement slope A, the operation is light and smooth.
