Description

[0001]
[Industrial application fields]
The present invention relates to a container with a dropper that takes out the content liquid stored in the container body with a dropper inserted into the container body, and is assembled inside the mouth tube portion of the container body, outside the suction pipe of the dropper inserted into the container body. The present invention relates to a squeeze plug that removes the content liquid adhering to the surface using a dropper in and out of the container body.
[0002]
[Prior art]
There is a known container with a dropper that uses the liquid stored in the container body with a dropper attached to the cap, but this container with a dropper is closed when the cap is in the closed position. As a result, the dropper is pulled out from the container with a large amount of content liquid adhering to the outer surface of the suction tube. In addition to the occurrence of dripping, there is a disadvantage in that it adheres to the mouth tube portion of the container body and causes dirt, and the opening and closing of the container body by the cap is defective.
[0003]
As a representative prior art for solving this inconvenience, the technology disclosed in Japanese Utility Model Publication No. 4-23819 discloses that the content liquid is placed in the inner periphery of the insertion opening of the container main body containing the content liquid. A ring-shaped contact ring is fixedly protruded through a formation interval that can be moved to the position, and a dropper suction tube can be inserted and removed through the contact ring.
[0004]
In the above-described prior art, the dropper is attached to the outer surface of the suction pipe by moving the dropper into and out of the container body while the inner peripheral surface of the contact ring is in contact with the outer surface of the suction pipe of the dropper. The content liquid is crushed by the contact ring, preventing the content liquid adhering to the outer surface of the suction tube from dropping and causing the content liquid to improperly adhere to the insertion port of the container body. The advantage is that it can be made difficult.
[0005]
[Problems to be solved by the invention]
However, in the above prior art, since the contact ring for removing the attached content liquid is based on a simple cylindrical structure, the content liquid that has been removed is substantially uniform throughout the lower end edge of the contact ring. For this reason, dripping and refluxing from the contact ring of the content liquid that has been squeezed into the container body is not achieved smoothly, and a large amount of the content liquid remains attached to the contact ring, resulting in a short period of time. In particular, there is a problem that the squealing ability by the contact ring is remarkably lowered.
[0006]
In addition, since the contact ring has a simple cylindrical structure as its basic structure, the squeezed content liquid tends to stay between the contact ring and the suction pipe of the dropper. There is a problem that the content liquid squeezing ability of the contact ring cannot be fully exhibited due to staying in between.
[0007]
Further, the contact ring is configured as a part of the inner plug that is tightly fitted into the insertion opening of the container body, and the inner plug integrally provided with the contact ring is injection-molded with a soft synthetic resin material or the like. In this case, the basic structure of the contact ring is a straight cylindrical shape having a certain height, so that it is difficult to smoothly release the inner plug, which is an injection molded product, from the mold. It was.
[0008]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and stably exhibits the high squeak ability of the content liquid and obtains a structurally smooth and stable release operation. Therefore, it is possible to obtain a safe and efficient molding operation while eliminating the inconvenient dripping of the contents liquid and the inadvertent adhesion to the mouth tube portion of the container body. With the goal.
[0009]
[Means for Solving the Problems]
The structural means of the present invention for solving the above problems is as follows.
It is a mushroom plug made of a soft material having elasticity, which is assembled into the mouth tube portion of the container body for inserting the dropper and taking out the content liquid,
A pair of squirrel pieces that elastically contact the projecting end edge with the outer peripheral surface of the dropper suction pipe are disposed opposite to the inner peripheral surface of the fitting cylindrical piece that is tightly fitted into the mouth tube portion of the container body,
Each of both sword pieces projecting in a spiral manner over a substantially half-circumferential region range,
Forming a slight separation gap along the circumferential direction between one lower edge and the other upper edge of both shigaki pieces;
It is in.
[0010]
It is preferable that the stalk piece has a cross-sectional shape that is inclined downward toward the protruding end.
[0011]
It is effective to set the spiral direction of the stalk piece to the reverse screw direction from the thread of the cap body assembled with the dropper.
[0012]
[Action]
When removing the cap with a dropper from the mouth tube of the container body and pulling out the suction pipe of the dropper from the container body, the content liquid adhering to the outer peripheral surface of this suction pipe is crushed by the crushed piece of the squeaker plug. Reflux into the container.
[0013]
When the dropper suction pipe is pulled out from the container body, the squeeze piece that squeezes off the content liquid adhering to the outer peripheral surface of the suction pipe has its protruding end elastically contacted with the outer peripheral surface of the suction pipe. It will be elastically contacted with the outer peripheral surface in a line contact state. Therefore, the elastic contact state with respect to the outer peripheral surface of the suction pipe is caused by a large amount of content liquid entering between the outer peripheral surface of the suction pipe and the protruding edge of the sledge The inconvenience of deterioration is less likely to occur.
[0014]
Since a pair of squirrel pieces spirally arranged over a substantially semi-circumferential region range are disposed opposite to each other, the squeeze pieces are elastic over substantially the entire outer peripheral surface of the dropper suction pipe except for the portion where the separation gap is opposed. As a result, the stagnation of the entire circumference of the suction pipe outer peripheral surface by both squirrel pieces is achieved, and each squirrel piece is provided in a spiral shape, that is, in a posture inclined along the circumferential direction. Therefore, the content liquid that has been removed and attached to the sword piece flows down to the lower end edge of the sword piece quickly according to the inclination, and is dropped and refluxed as it is from the lower end edge of the sword piece into the container body.
[0015]
Since a slight separation gap is formed along the circumferential direction between the upper and lower end edges of both shigoki pieces, the inner circumferential surface of the fitting cylinder piece is in the direction along its central axis, i.e. A separation gap is formed along the mold opening direction of the mold for molding the gap that can be passed through without being disturbed by the squirrel piece. It is easy to easily achieve die removal from the molding die.
[0016]
By making the squeeze piece into a cross-sectional shape that is inclined downward toward the protruding end, the content liquid that has been squeezed away quickly flows and separates without staying in the vicinity of the elastic contact portion between the suction pipe and the squeeze piece. Become.
[0017]
By setting the spiral direction of the mushroom piece in a direction opposite to the screw thread of the cap with a dropper that is screwed into the mouth tube portion of the container body, the cap body is pulled up while being rotated in the screwing direction. Each sword piece is opposed to the outer peripheral surface of the suction pipe of the dropper which is rotated while relatively rotating, with a circumferential length larger than the actual circumferential length, thereby the outer circumference of the suction pipe. The protruding edge of the sword piece is elastically contacted in the entire circumferential direction of the surface.
[0018]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
FIG. 1 is a front view of a main part half-cut in a closed state of a container with a dropper assembled with a squirrel inner stopper 1 according to the present invention. The part 6 is closely fitted and assembled.
[0019]
A cap 7 with a dropper is detachably screwed to the mouth tube portion 6 of the container body 5 to which the shigoki plug 1 is assembled. The cap 7 with a dropper has a thread on the inner peripheral surface of the peripheral wall. A dropper 9 composed of a suction pipe 10 and a suction head 11 made of a soft elastic material assembled to the upper end of the suction pipe 10 is sucked into a cap body 8 having a cylindrical shape with a carved shape. The head 11 is assembled and protruded from the top wall of the cap body 8.
[0020]
An inner peripheral surface of a cylindrical fitting tube piece 3 having a cylindrical shape that is tightly fitted into a mouth tube portion 6 of a container body 5 is a shigoki inner plug 1 formed of an elastic soft material such as LLDPE (low pressure low density polyethylene). A pair of squirrel pieces 2 are provided so as to protrude from the upper end of the fitting tube piece 3, and an outer collar-like upper collar piece 4 for setting a fitting assembly limit with respect to the mouth tube part 6 of the squirrel inner plug 1 is provided around It is configured.
[0021]
Both squirrel pieces 2 are spirally provided over a substantially half-circumferential region of the inner peripheral surface of the fitting tube piece 3, and the spiral direction is a reverse screw direction with respect to the thread of the cap body 8.
[0022]
A slight separation gap S (see FIG. 3) is formed between the upper end edge of one squirrel piece 2 and the lower end edge of the other squeeze piece 2 so as to enable die cutting along the circumferential direction.
[0023]
In addition, the inner peripheral surface of the fitting cylinder piece 3 around which the squirrel piece 2 is provided is divided into an upper part and a lower part with the squirrel piece 2 as a boundary, and each is provided with a slight punching taper.
[0024]
FIG. 4 shows another embodiment of the present invention, in which the squirrel piece 2 is configured to have a cross-sectional shape inclined downward toward the protruding end, and the squirrel piece 2 elastically contacting the outer peripheral surface of the suction pipe 10. Since the lower side, which is the side of the squeal, becomes an obtuse posture with respect to the outer peripheral surface of the suction tube 10, the squeezed content liquid is less likely to adhere and stay on the bottom side of the squeeze piece 2, and quickly flows down.
[0025]
For this reason, a large amount of content liquid accumulates in the vicinity of the protruding end of the squirrel piece 2 that is in elastic contact with the outer peripheral surface of the suction pipe 10, and this accumulated content liquid enters between the suction pipe 10 and the squirrel piece 2, It is possible to reliably prevent the occurrence of inconvenience that the squeaking ability of the squealing piece 2 is reduced.
[0026]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
Since the squirrel pieces that squeeze the content liquid adhering to the outer surface of the dropper are spirally arranged in the circumferential direction, the squeezed content liquid is guided to the squeeze pieces inclined in the circumferential direction and quickly Since it flows down and concentrates at the lower end of the squirrel piece and then drops and refluxs into the container body, dropping and refluxing of the squeezed content liquid into the container body is achieved smoothly, promptly and reliably.
[0027]
A pair of mushroom pieces projecting on the inner peripheral surface of the cylindrical fitting cylinder piece is provided with a slight separation gap along the circumferential direction between the upper edge and the lower edge of each other, and the die cutting direction Therefore, it is possible to obtain a smooth and stable die-cutting, thereby enabling the molding of the scab stopper to be performed safely and efficiently.
[0028]
The squirrel piece has its protruding end elastically contacted with the outer surface of the dropper, and the squirrel piece itself has a cross-sectional shape that is inclined downward toward the protruding end, so that the squirrel piece is squeezed from the outer surface of the dropper The liquid does not stay in the vicinity of the elastic contact between the squirrel pieces and the outer surface of the dropper. It can be demonstrated reliably.
[0029]
By setting the spiral direction of both stalk pieces to the reverse screw direction with respect to the thread of the cap, it becomes possible to substantially increase the length along the circumferential direction in elastic contact with the outer surface of the dropper. Despite the provision of the separation gap, the stalk piece can be elastically brought into contact with the entire circumference of the dropper outer surface, and a more complete squeeze removal of the content liquid adhering to the dropper outer surface can be obtained.
