Description

  The present invention relates to a technique for improving the usability of a fluid extrusion container.

  Examples of containers for dropping liquids and other fluids include the eye drop containers disclosed in Patent Document 1 below, but the caps must be removed each time they are used, and they may be said to be relatively small members. There was also the possibility of contamination.

  In addition, a cap-integrated container is also introduced, and a container that can squeeze the container portion without dropping the cap by a simple series of operations and take out the fluid is also employed (for example, Patent Document 2 below). reference.).

JP 2004-89609 A JP 2008-230624 A

However, the container described in Patent Document 2 has the following problems.
That is, the edge portion of the container is relatively hard from the viewpoint of maintaining the shape retaining property, and in order to cause deformation of the container with a light force, the upper edge of the lid is formed into a shape protruding in an arc shape, or It must be molded into a shape that facilitates pressurization such that the height or depth of the lid is longer than the thickness of the cap body.

At that time, if the thickness of the cap body is reduced, sufficient mounting strength cannot be obtained due to insufficient covering thickness, and the housing is a more flexible portion than the end when pressing the housing. The cap may not be able to contact the center of the body.
Conversely, as shown in FIG. 6 of Patent Document 2, when the thickness of the cap is increased, the cap can be brought into contact with the vicinity of the center of the container, which is a more flexible portion than the end portion. In this case, even a slight distortion of the hinge part is amplified by the distance and transmitted to the top of the cap.

  The present invention has been made in view of the above circumstances, and has a simple configuration capable of dropping a fluid without dropping a cap that has been removed by a simple series of operations, and a sealing failure occurs. The object is to provide a container for fluid extrusion that is difficult.

  A fluid extruding container according to the present invention, which has been made to solve the above problems, comprises a hollow container having an injection port and a cap attached to the injection port, and the cap has the injection port. A cap body having a spout that is mounted on and protruded, a cover that is less than the thickness of one finger that covers the upper end of the cap body, a corner that reaches the flexible part of the container at an open limit angle, and a sealed state The lid portion having a stopper that fits into the spout and the hinge portion that connects the lid portion and the cap main body so as to be openable and closable are integrally formed, and the container does not interfere with the lid body. It is characterized in that it has a flexible part that is deformed so that the volume is reduced by an opening operation exceeding the generated opening limit angle, and the deformation is recovered by returning the lid part to an opening limit angle. To do.

  As long as the object of the present invention can be achieved, the shape and size of the corner portion are not limited, but the shape is particularly inclined toward the hinge portion when viewed from the center of the cap. A corner portion (hereinafter sometimes referred to as a “corner portion in the forward direction”), or conversely, a corner portion having a shape inclined toward the opposite side of the hinge portion as viewed from the center of the cap ( Hereinafter, it may be referred to as “a corner portion in the opposite direction”).

  When the corner portion in the positive direction is provided, the corner portion can easily reach the flexible portion of the container, and it can be prevented from being accidentally opened by becoming a smooth shape toward the opening direction. An effect is obtained. On the other hand, when the opposite corner is provided, it is difficult for the corner to reach the flexible part of the container, but it is easy to open the cap by putting a finger on the corner. The effect that the cap can be easily opened is obtained without providing the protruding piece separately.

  Regardless of which installation direction is employed, there are advantages, respectively. Therefore, it is preferable to properly use them depending on the size of the container, the assumed user, the usage scene, and the like. Further, if necessary, for example, as shown in FIGS. 9E and 9F, both the forward and reverse corners may be provided at the same time.

  As for the size of the corner, it is usually about 0.3 to 10 times, preferably about 0.5 to 5 times, more preferably 0.8 to 3 times the height of the cover (5a). Degree. In addition, the corner portion needs to have a thickness or thickness that can secure a strength enough to withstand a pressing operation.

  In the present invention, it is preferable that the cover (5a) is provided with a projecting piece that serves as a clue to release the sealing other than the corner portion, if necessary. The position of the projecting piece is not particularly limited as long as it can be easily opened by the user. In particular, the projecting piece is preferably provided at the end of the cap lid on the side opposite to the hinge. By providing the projecting piece at this position, for example, as shown in FIG. 4, the user can perform a series of operations from opening to extruding the fluid without changing the position of the finger at all. .

  The lid portion and the cap body are integrated with a hinge portion that can be freely opened and closed, and the container is small in volume by an opening operation that exceeds an open limit angle where interference with the lid body of the lid occurs. By the structure having a flexible portion that is deformed as described above, and the deformation is recovered by returning the lid portion to within the open limit angle, for example, during the extrusion operation, the tip portion of the lid portion is a force point, and the hinge The portion is a fulcrum, and the contact point between the corner and the container is the point of action, and the fluid can be dropped in one action by a series of operations on the lid.

  By providing a corner on the surface of the cover that reaches the flexible part of the container with the lid open, there is no need to incorporate various functional requirements such as an increase in the size of the cover into the design, and twisting or sealing of the hinge Defects can be prevented. Moreover, even if it is at the time of extrusion operation, it can apply a reliable press to a flexible part irrespective of the form of a cover. Furthermore, by providing a corner, depending on the direction, it can also be used as a part (pressing member) where a finger is applied at the time of opening, so the spout is contaminated by the finger touching through the gap between the cap and the cap body. Can be prevented.

  In addition, by making the cover that covers the upper end of the cap body less than the thickness of one finger, the cover becomes less bulky, resulting in poor sealing due to misopening, twisting of the hinge, etc. In addition, since the stopper is shortened, the facing position of the stopper and the spout is stabilized, and the operation at the time of sealing becomes easy.

  In particular, when a corner that has a slope that extends substantially uniformly from the hinge side to the projecting piece, such as a corner that rises upward from the projecting piece toward the hinge, is used. Therefore, it becomes a smooth shape in the opening direction, and erroneous opening due to a finger or other object caught on the corner can be prevented.

Hereinafter, embodiments of a fluid extrusion container according to the present invention will be described with reference to the drawings.
The fluid extruding container according to the present invention is configured by integrating a flexible container (container) 1 and a cap 3 attached to the injection port 2 by screwing or fitting. .

  The cap 3 includes a cap body 4 having a spout 4a that is attached to the inlet and protrudes from substantially the center, a lid 5 for covering the upper end of the cap body 4 and sealing the spout 4a, and the lid A hinge portion 6 that connects the portion 5 and the cap body 4 so as to be openable and closable with a substantially constant track is integrally formed of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), or the like. Become.

  The container 1 is formed of the same material as the cap 3 and is deformed so that the volume is reduced by an opening operation accompanied by an extrusion operation, and the deformation is restored and recovered by releasing the extrusion operation. Part 1a.

  The lid 5 includes a cover 5a that covers the upper end of the cap body 4, a corner 5b that presses the side of the container, a plug 5c that fits into the spout 4a, a partition wall 5d that surrounds the plug 5c in a cylindrical shape, and an open / close A protruding piece 5e that receives an operation from a finger is provided.

  The cover 5a of the lid 5 in this embodiment is formed in a circular dome shape and has a thickness that is less than the thickness of one finger. At the center of the back surface of the cover 5a, a stopper 5c for sealing the spout 4a is projected in the form of a bottomed cylinder, and the periphery of the stopper 5c is close to the spout 4a when closed. A cylindrical partition wall 5d is provided so as to surround the periphery (see FIGS. 1B and 1D).

  At the tip of the lid 5 (opposite to the hinge 6), a protruding piece 5e with which the user's finger is attached at the start of the opening operation and the extrusion operation is integrally provided. The projecting piece 5e may be oriented either horizontally or downward, and a portion that serves as a clue for the opening operation may be provided separately.

Moreover, the corner | angular part 5b which reaches the flexible part 1a of the container 1 in the state which open | released the cover part 5 is integrally provided in the surface of the said cover 5a.
The corner 5b shown in FIG. 1 includes a slope having a substantially uniform width that rises upward from the vicinity of the hinge 6 toward the protruding piece 5e, and has a rising surface that extends from the upper end to the vicinity of the center of the cover 5a.
The width of the slope or rising surface can be designed to be wide or narrow depending on the design of the lid 5, and the cover 5 a and the corner 5 b are not limited to the shape consisting of the slope and the rising surface. It is also possible to design the character's head (see FIGS. 11 to 14) and various shapes as shown in FIG. Further, as shown in FIGS. 10E and 10F, even if a plurality of corners 5b are provided, the corners 5b where the fingers are missing when the cap is opened and the corners 5b that press the flexible part 1a are individually formed. good.

The upper end of the corner portion 5b is configured to facilitate extrusion of an amount of fluid according to the application by pressurizing the flexible portion 1a of the container 1.
Since the example is an eye dropper container, in the extrusion operation sufficient for the content extraction, the flexible portion 1a is not damaged (perforated, etc.) or excessively consumed every time the extrusion operation is performed. A form in which the amount of eye drops can be dispensed.

  Specifically, for example, a plate-shaped pressurizing strip 5ba having a volume substantially equal to the amount of eye drops applied once or a smooth upper edge is formed on the upper end of the corner portion 5b with respect to the flexible portion 1a. It shape | molds so that it may become parallel (refer FIG.1 and FIG.2 etc.), or spherical pressure ball 5bb is shape | molded on the upper end of the corner | angular part 5b (refer FIG.5, FIG.6 etc.). At this time, the diameter or width of the pressurizing strip 5ba, the diameter of the pressurizing ball 5bb, or the like may be made substantially equal to the depth and width of the press capable of realizing the one-time content extraction, for example.

  When the rising surface is used together with the protruding piece 5e as a clue to the opening operation, the rising surface faces the protruding piece 5e and is recessed into an arcuate shape so that the finger is easily engaged (for example, FIG. 1, FIG. 2, (See FIG. 5, FIG. 7, and FIG. 8.) On the other hand, when emphasizing prevention of accidental plugging, the rising surface faces the protruding piece 5e so that the slope that descends substantially uniformly from the hinge side to the protruding piece becomes the upper edge, and has a smooth bow shape. It is inflated so that the external force applied in the opening direction is easily released (see FIG. 6).

  The cap includes an engaging portion 5f having an unevenness on the inner peripheral edge of the cover 5a in the lid portion 5, and a notch portion 4b having an unevenness to fit the engaging portion 5f on the upper peripheral edge portion of the cap body 4. Prepare. The unevenness of the locking portion 5f and the unevenness formed in the cutout portion 4b of the cap body 4 are fitted and integrated with each other, whereby the sealed state of the lid portion 5 is maintained.

  In the above-described embodiment, the protrusion 5e of the lid 5 is a force point, the hinge 6 is a fulcrum, and the tip of the corner 5b of the lid 5 is an action point during the extrusion operation. The position and shape of the lid 5 are set.

  According to the fluid extrusion container, as shown in FIG. 1, the lid 5 can be opened and closed with one hand by swinging the lid 5 with the hinge 6 as a fulcrum. Moreover, the fluid can be pushed out from the spout 4a by one action by a series of extrusion operations (see FIG. 4) such as moving the thumb in the direction of the arrow in FIG. 1B. For example, for eye drops When used as a dripping (instillation) container, an appropriate amount of eye drop can be dripped quickly, and there is no possibility of dropping or losing the lid 5.

  Moreover, in the said embodiment, since the said hinge part 6 comprises the linear thin part 7 used as a crease | fold (refer FIG. 1), opening and closing of the said cover part 5 is possible. Since the swinging trajectory is stable without large lateral swing, the pushing operation and the opening / closing operation are not delayed due to the twist of the hinge portion 6 or the like.
