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'' With this type of cap, there is no need to remove the cap from the container each time when dispensing the contents.
Widely used in squeeze-shaped shampoo containers, etc.

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 the need for these hinges increases. In this case, in order to obtain the hinge effect that keeps the lid open, it is necessary to manually open the lid to an almost upright position, and it is difficult to open the lid with one hand while holding the container with the other hand. .

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 is provided with an external peripheral wall 6 around the mounting peripheral wall 5, and a straddle seat 8 is recessed in the front part of the top wall 7. A cap body 1 with a spout hole 9 in the inner top wall 7, and a ladder-shaped piece 10 from the top.
An actuator 2 is installed vertically on the straddle seat 8 so as to be slidable in the left and right direction, and a bar stopper 11 that is inserted into the spout hole 9 from the back side is installed vertically.
an engagement plate which is pivotally mounted on the upper surface of the cap main body 1, has a ladder-shaped notch 13 corresponding to the piece 10 of the actuator 2 cut out from the back side of the front side, and engages with this piece 10 from the upper surface; Opening/closing lid 3 with 14 installed vertically
and a normally open/close lid 3 mounted on the hinge 12.
Push the bar plug 11 in the opening direction and slide the actuator 2.
It is comprised of a drive spring 4 that opens the opening/closing lid 3 rearward when it leaves the pouring hole 9. .

"Function" In the above, normally the opening/closing lid 3 is in the closed state as shown in FIGS. Straddle 8
The piece 10 engages with the engagement plate 14 on the opening/closing lid 3 side, and the slopes A and B are in contact with each other. The rod stopper 11 is firmly inserted into the pouring hole 9, so that the frictional force therebetween exceeds the opening force of the drive spring 4, and the opening/closing lid 3 remains closed.

If you want to open the cap or lid from this state, please use the container body 1.
5, and place the thumb of this hand, for example, on the front surface of the actuator 2, and use this thumb to slide the actuator to the left or right. Then, the moving piece 10 pushes up the engagement plate 14, that is, the opening/closing lid 3, through the contacting slopes A and B, so that the rod stopper 1
1 is removed from the spout hole 9. Therefore, after this, the drive spring 4 opens the opening/closing lid 3 rearward. That is, the opening/closing lid 3 can be opened with one touch by sliding the actuator 2 a small distance.

``Embodiment'' The cap of the present invention includes a cap main body 1 that is attached to the mouth and neck part 17 of a container body 15, an actuator 2 that is provided on the front part of the top wall 7 of this main body 1 so as to be slidable in the left and right direction.
An opening/closing lid 3 is pivotally provided on the upper surface of the cap body 1 by a hinge 12 and is engaged with an actuator 2, and a driving spring 4 is mounted on the hinge 12 and always biases the opening/closing lid 3 in the opening direction. Consisting of

In the cap body 1, the mounting peripheral wall 5 has a round cylindrical shape, and the external peripheral wall 6 has a rectangular cylindrical shape that matches the shape of the container body 15.
The mouth and neck part 1 of the container body 15 are screwed into the mounting peripheral wall 5.
7 will be installed. The straddle seat 8 has a downward U-shaped cross section, and the rear end of the top wall 7 is recessed so that the hinge 1
There are 2 mounting parts. Reference numeral 18 denotes a ring stopper hanging from the back surface of the top wall, and is fitted inside the mouth and neck part 17.

As shown in FIG. 2, the actuator 2 has a downward U-shaped cross section and is mounted to straddle the straddle seat 8. A non-slip member 19 is provided on the front surface of the front plate, and a lateral engaging member is provided on the rear surface of the rear plate. A mating protrusion 20 is provided, and this rear plate is engaged with a groove behind the straddle seat 8, and the engaging protrusion 20 is engaged with an engagement groove on the corresponding surface of this groove to prevent it from coming off. .

The hinge 12 of the opening/closing lid 3 has a hinge boss 12a that engages with a concave portion at the rear end of the cap body 1, and this boss 12a is pivoted to a fixed portion on the body 1 side with a hinge pin 12b. A rod stopper 11 is firmly inserted into the pouring hole 9.

As the drive spring 4, a well-known spring with mustaches is used. That is, a coiled spring body 4a is mounted on the hinge pin 12b, one end of the bead 4b is applied to the fixed side, and the other end of the end bead 4c is applied to the movable side, so that the spring force is always applied to the movable side, that is, the opening/closing lid 3. It is installed so that it acts as a force to open the lid.

Note that 21 is a protrusion or protrusion that presses against the mounting peripheral wall 5 of the cap body 1 and prevents it from rotating. Each part except the drive spring 4 is molded and manufactured from synthetic resin material.

"Effects of the Invention" As described above, according to the present invention, since the cap body 1, the actuator 2, and the opening/closing lid 3 are made into separate members, the molding molds are also of three simple shapes, which simplifies the processing.
Further, a drive spring 4 is provided on the hinge 12 of the opening/closing lid 3, so that when the slide opening/closing lid 3 of the operator 2 at the upper front is pushed up and the bar stopper 11 is disengaged from the spout hole 9, it automatically opens rearward. This makes it convenient to use as you can open the bottle and lid with one hand. In addition, since the actuator 2 passes through slopes A and B, the operation is light and smooth.
