Description

Description Liquid container Technical field

The present invention relates to a liquid container, and more particularly to a liquid container such as a cleaning liquid container for storing a cleaning liquid used in medical institutions such as hospitals and health centers. & Scenic fe

Conventionally, in medical institutions such as hospitals and health centers, cleaning solutions such as saline, water for injection, distilled water, and disinfectant have been used for cleaning surgical instruments and affected areas of patients. Such a cleaning liquid is enclosed in a bag-type / bottle-type cleaning liquid container, and two types of liquids are usually used, one for small-diameter opening and one for large-diameter opening.

Of these two types, small-diameter openings are used for fine cleaning such as cleaning small wounds of patients and partial cleaning of wounds, or partial cleaning of medical instruments, and require strong spraying. Suitable for the case.

The large-diameter opening is suitable when a large amount of cleaning liquid needs to be supplied at one time, for example, for cleaning the entire wound of a patient or the entire medical device.

However, such conventional cleaning liquid containers have to store two types of liquids depending on the application, which not only requires a large storage space but also requires individual inventory management, which is troublesome. .

On the other hand, a cap for sealing the mouth of the container body is connected to a sealing part via a large-diameter cutting part. A washing container has been proposed which is provided with a threaded portion which is provided with a threaded portion and which can form a threaded small-diameter opening by screwing a knob portion in the sealing portion (see Utility Model No. 30). (See Japanese Patent Publication No. 0 9864).

In the cap of this washing container, the torsion of the knob can select either the small diameter opening or the large diameter opening by pulling the pull ring to form the opening. As a result, the storage space can be reduced and inventory management becomes easier.

However, since the size of the pull ring (pull ring) through which the finger passes (the inner diameter of the ring) is constant, it is very difficult for those who do not match the size of the finger. The operability is poor because it is necessary to pull up from a narrow space or to hook a finger. In addition, both the pull ring and the knob have an undercut in molding, making it difficult to remove the mold, and therefore, molding cannot be said to be easy.

Therefore, one of the main objects of the present invention is to provide a liquid container that has a thimble structure, is easy to mold, and is easy to form an opening.

Another main object of the present invention is to provide a liquid container that is easy to select and form a small-diameter opening and a large-diameter opening. Disclosure of the invention

The present invention comprises a container body having a mouth and containing a liquid, and a cap for sealing the mouth of the container body.

The cap can be attached to the periphery of the mouth of the container body, and has a first opening, a main body, a body, and a lower peripheral part of the body at the first opening of the main body. It consists of a flange that is integrally connected via a connecting part, and the first connecting part of the bracket is weakened so that it can be separated by the force applied to the trunk. Provided is a liquid container characterized by the following.

That is, in the liquid container according to the present invention, the first connecting portion is weakened so as to be separable by the force applied to the body, so that the first opening is formed with a very simple configuration and with a simple operation. Can be formed. Specifically, for example, the cap is obtained by injection molding at a time with three molds consisting of a pair of outer molds symmetrical to the left and right and one inner mold pressed down from the bottom, so there is no undercut. Die cutting becomes easy. In addition, the opening (first opening) can be formed by applying a force to the body, for example, by laying down instead of pulling, so that the operation is simple.

Further, according to the present invention, the trunk and the flange are provided near a first connecting portion (a weakened portion) between the part of the lower peripheral surface of the trunk and the main part of the cap along the upper surface of the flange. If the ribs are provided integrally to assist in separating the first connecting part by the side-down operation, even if the diameter of the first opening is large, the force to tilt the body sideways This is preferable because it is transmitted along the rib to the corresponding portion of the first connecting portion and the first opening can be easily opened.

Further, in the present invention, the body has a second opening having a diameter smaller than the first opening of the cap main portion at an upper portion, and a lower end peripheral portion is provided with a first opening portion of the cap main portion via a flange portion. The main body is integrally connected to the main body, and the top is integrally connected to the second opening through the second connecting part.The second connecting part is weakened so as to be separable by the force applied to the top. When the first connecting part is weakened so that it can be divided by at least the force applied to the torso main part, that is, the simultaneous force applied to the torso main part and the top part, or by the force applied only to the torso main part, the small diameter The opening (second opening) can be selectively formed by applying force to the top, and the large-diameter opening (first opening) can be selectively formed by applying force to the main body. This is easy because molding is possible by an injection molding method without difficult die cutting. Here, the phrase that the first connecting portion is weakened to be separable by the force applied to the torso means that the first connecting portion is broken by the relative force applied to the torso while holding the cap main portion. In order to form an opening having a desired diameter, the first connecting portion is made thinner, or a V-shaped groove, a perforated cut line, or the like is attached to the other portion to form an opening having a desired diameter. It means that the mechanical strength is weakened. Also, the fact that the second connecting portion is weakened so as to be separable by the force applied to the top portion means that the second connecting portion holds the cap main portion and the torso main portion while holding the cap main portion and the trunk main portion relative to the top portion. It means that the mechanical strength is weakened as in the above case, so that the application force is divided by, for example, an operation of applying a rotational force around the axis, thereby forming an opening having a desired diameter. As a top portion suitable for applying a rotational force about the axis in this manner, there is a knob portion having a butterfly wing shape in which the opening direction of the butterfly wing is perpendicular to the sideways direction of the trunk. . Preferably, the thickness of the second connecting portion is the same as or smaller than that of the first connecting portion. Of course, in both the first connection part and the second connection part, the liquid container is subjected to pressure, collision, or contact during normal handling (during normal proper production, holding, delivery, etc.). , Etc.) requires mechanical strength that is not divided by the force received. In addition, when loading or transporting trucks or other vehicles, it is speculated that unexpected force may be applied to the cap, resulting in unexpected formation of openings. However, the cap cover will not affect the internal cab.

The cap main part is attached to the periphery of the mouth of the container body. Specifically, the lower end peripheral surface of the cap main part is welded or bonded to the upper end peripheral surface of the mouth part of the container main body. If the mouth of the container body projects cylindrically, The cap main part can be easily attached to the mouth of the container main body by fitting the main part of the cap to the outside or inside of the mouth, that is, by fitting, welding or bonding.

According to another aspect of the present invention, there is provided a container body having an opening, a liquid contained in the container body, and a cap for closing the opening of the container body. A cap main part which can be attached to the periphery of the mouth and has a first opening, a trunk, and a lower end peripheral part of the trunk integrated with the first opening of the cap main part via a first connecting portion; It is possible to provide a liquid container comprising a connected flange portion, wherein the first connection portion of the bracket is weakened so as to be separable by the force applied to the body portion.

According to yet another aspect of the present invention, there is provided a liquid container cap for sealing a mouth portion of a liquid container body, the cap main portion being attachable to a periphery of the mouth portion of the container body, and having a first opening. A trunk portion, and a flange portion integrally connecting a lower end peripheral portion of the trunk portion to a first opening portion of the cap main portion via a first coupling portion, wherein the first connection portion of the bracket is a trunk portion. Caps for liquid containers characterized by being weakened so that they can be separated by the force applied to the container, can be sealed to the mouth of the container body of various specifications (for example, those with different capacities). Can be used as a common cap. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, the present invention will be described in detail based on each embodiment shown in the drawings. Note that the present invention is not limited to this.

FIG. 1 is a front view showing an embodiment of the liquid container according to the present invention, FIG. 2 is an enlarged cross-sectional view of a main part of FIG. 1, FIG. 3 is an enlarged cross-sectional view of a main part in a cross section different from FIG. Is a perspective view of the main part without the cap cover, FIG. 5 is a view as seen from the direction of arrow A in FIG. 4, FIG. 6 is a plan view of FIG. 5, and FIG. 7 is a front view of the cap cover of FIG. It is.

First, in FIGS. 1 to 3, a cleaning liquid bottle 1 as a liquid container is fixed to a bottle body 2 containing a physiological saline or water for injection (not shown) as a cleaning liquid and a mouth 3 of the bottle body. It mainly comprises a cap 4 for sealing the part 3 and a separate cap cover 5 detachably engaged with the cap.

The bottle body 2 is a box-shaped bottle (container) obtained by a lip-opening molding method of polypropylene resin, and after pouring saline or water for injection (about 100 m 1) from the mouth 3 thereof. A cap 4, which will be described later, is sealed to the upper peripheral surface of the mouth 3 by integrally welding the lower peripheral surface, that is, the lower flange portion 6.

By the way, the cap 4 is integrally formed by a blow molding method of polypropylene resin (for example, the wall thickness: about 1.0 mm on average). In particular, in FIGS. Cap main part 7 to be A main body 8 formed on the main part of the cap, and a lower peripheral edge of the main body, and a flange 9 integrally connected to the first opening 19 of the main part 7 of the cap. Further, the trunk portion 8 has a second opening portion 20 having a diameter smaller than the first opening portion 19 of the cap main portion 7 at an upper portion, and has a lower end peripheral portion via the collar portion 9. 7 comprises a torso main portion 8a integrally connected to the first opening portion 19, and a top portion 8b formed on the torso main portion and above the second opening portion 20. The inner peripheral surface of the cap cover 5 is provided with an engaging ridge 17, and the outer peripheral surface of the cap main part 7 is provided with a groove 18 as an engaging concave portion engaging with the engaging ridge 17. Has formed.

The flange 9 has a thin neck portion 10 for forming a large-diameter opening as a first connecting portion in the first opening portion 19 of the cap main portion 7 (for example, a V-shaped groove-shaped bottom portion having a thickness of about 0.1 mm). 4 mm), and the ribs 8 and 9 extend radially from a part of the lower peripheral surface of the trunk 8 to the vicinity of the thin neck 10 along the upper surface of the flange 9. The thin neck portion 10 can be cut only when the body portion 8 is pressed, that is, when the body portion 8 is turned sideways (the thin neck portion 10 cannot be cut even by twisting the knob portion 13 described later). Thus, a large opening (diameter: about 18 mm) can be formed.

The top portion 8b is provided with a small-diameter opening-forming thin-walled neck portion 12 as a second connecting portion (for example, a V-shaped groove having a bottom portion thickness of about 0. 4 mm) and a butterfly wing-shaped knob 13 on the thin neck. If this knob 13 is pressed, that is, twisted, only the thin neck 12 is twisted off. (Without twisting the thin neck 10), thereby forming a small diameter opening (diameter: about 6 mm).

As described above, the cleaning liquid bottle 1 can easily form only the large-diameter opening by operating the body 8 sideways, and the cleaning liquid flows out from the large-diameter opening at a stretch. Therefore, it can be used for cleaning the whole wound of the patient or the whole medical device. On the other hand, if the knob 13 is twisted, only the small-diameter opening can be formed, and the washing solution can be gradually discharged from the small-diameter opening, and thereby the small wound part or a part of the wound part of the patient can be formed. Can be provided for cleaning.

In short, the cleaning liquid bottle 1 can selectively form a small-diameter opening and a large-diameter opening so that one bottle with one dimensional specification can be used for two cleaning purposes, and one type of liquid container can be stored. And storage space can be reduced, and inventory management becomes easier.

Further, the cleaning liquid bottle 1 is particularly easy to mold because the cap 4 can be molded (molded) by an injection molding method. Specifically, for example, the cap 4 is difficult to obtain because the cap is obtained by injection molding at a time with three molds including a pair of outer molds symmetrical left and right and one inner mold pressed down from the bottom. It is easy to mold without removing the mold, and is also used as a common cap for the mouth of other specification container body (for example, volume of 200 ml, 500 ml, 100 m1) it can. Further, the cleaning liquid bottle 1 is configured such that the first and second connecting portions (thin neck portions 10 and 12) are integrally formed by different operation methods for the body portion 8 (main body portion 8 a) and the knob portion 13 of the cap 4. The operation is easy to understand because it can be divided and a small diameter opening and a large diameter opening can be selectively formed.

Note that, unlike the above embodiment, the container body of the liquid container may be a liquid bag (bag) formed of a flexible sheet. Also, as in the embodiment, the cap cover has a convex portion or a concave portion on the inner peripheral surface of the cap cover, and can be detachably attached to the convex or concave portion of the cap cover on the outer peripheral surface of the main portion of the cap. May have an engaging concave portion or an engaging convex portion to engage with, but is detachably engaged with the mouth of the container body or in the vicinity of the mouth. May be. The cap cover may be fitted or screwed to the container body or the cap main part in a liquid-tight manner. For example, a thread may be formed on the inner peripheral surface of the cap cover, and a thread may be formed on the outer peripheral surface of the cap main part to be screwed with the thread of the cap cover. The liquid stored in the liquid container may be a cleaning liquid such as distilled water or a disinfecting liquid (eg, ethanol for disinfecting), or may be neutral water or a cleaning liquid for contact lenses. Further, the number of ribs provided over the body and the flange is not limited to one, and may be two or more. Further, when these ribs are provided in different directions, the openings can be formed by the force from each direction. For example, if ribs are provided in one direction (0-degree direction) and the direction located at 90 degrees (90-degree direction) around the torso, the force (operation ), The opening can be formed, and the opening can be formed even when the force (operation) is applied from the 90-degree direction.
