Description

[Detailed description of the invention] Industrial application field This invention is applicable to medical liquids such as distilled water and physiological saline,
It also relates to plastic containers for foods such as liquid seasonings and other liquid substances.

Conventional technology A plastic container for medical fluids such as distilled water or physiological saline has a small diameter opening for local cleaning of an affected area, and is used for cleaning surgical instruments, cleaning the affected area, diluting injection solutions, etc. A structure that allows opening with a large diameter when a large amount of liquid is used at one time is already known, for example, as described in Japanese Utility Model Application Publication No. 159550/1983.

Problems to be solved by the invention By the way, the conventional device described in the above publication has a structure in which both the small-diameter opening and the large-diameter opening are cut open and sealed by screws. The edge becomes an irregular uneven edge, and when the container is tilted to pour out liquid from a large-diameter opening, the liquid that flows out waves and scatters around. When discharging physiological saline to the affected area, the problem was that it did not come out straight.

In addition, the large diameter opening does not have a part to hang your fingers on when twisting it, and when opening the large diameter opening, the sealed part must be screwed off with quite strong force. Not only was it not easy to open the container because it had to be turned left and right repeatedly, but the problem was that the container would shake and the liquid would overflow when the container was opened.

Furthermore, when screwing on the lid, the above conventional method not only has the disadvantage that if the lid is tightened excessively, the large-diameter opening may be opened by mistake, and once the large-diameter opening is opened, it will no longer be possible to re-open the lid. It has the disadvantage that it cannot be sealed.

In view of this problem, the present invention allows the spout at the upper end to be opened to both a small diameter and a large diameter, and when opening the large diameter, simply hook your finger on the protrusion and twist it. The opening operation is extremely easy, and not only does the liquid not overflow, but there are no irregularities on the edge of the large diameter opening, which allows the liquid to flow out smoothly when the container is tilted to pour out the liquid. The liquid does not scatter when pouring out, and a small diameter opening is formed at the top of the ridge on the top wall to concentrate the liquid when pouring a small amount, making it easy and reliable to pour into small diameter containers, etc. In particular, by forming protrusions that can be twisted by hooking fingers on opposite positions of the slope of the conical ceiling wall, when opening a large-diameter opening, the conical ceiling wall can be twisted easily. You can place your hand along the slope and hang your fingers on the protrusion, apply twisting force efficiently and evenly to the thin annular part, and easily open a large diameter opening. The object of the present invention is to provide a plastic container in which the liquid is stored in the virtual cylindrical space of the pouring spout portion of the conical top wall so that the spout portion does not get in the way.

Means for Solving the Problems In order to achieve the above object, the present invention is constructed as follows.

In other words, the structure is a sealed plastic container for liquids that has a spout at the top end, and a part of the top wall that seals the spout at the top is raised upward in a conical shape. A thin annular part is formed around the top wall that surrounds most of the rim of the spout, and at opposite positions on the slope of the conical top wall, protrusions on which fingers can be hung and twisted are formed, as well as raised ridges. The plastic container is characterized in that a small-diameter thin-walled part is formed at the apex of the part, and a lift-up ring is connected to the upper side of the small-diameter thin-walled part.

Function As described above, the plastic container according to the present invention has a part of the top wall that seals the spout at the upper end that is raised, and a thin annular part that surrounds most of the inside of the rim of the spout. In addition, since a finger-hanging protrusion is formed on the top wall, by simply placing a finger on this protrusion and twisting, the part surrounded by the annular thin-walled part presents an orderly cut and can be easily removed. , the spout has a large diameter opening. Therefore, the edge of the large-diameter opening is not uneven but has a smooth end surface, so that the liquid to be poured out flows out without undulating or scattering. In addition, since the large-diameter opening requires only twisting and cutting the part surrounded by the thin wall, the container can be opened with a small amount of force without shaking, and there is no risk of overflowing the liquid. .

Furthermore, since the small-diameter opening is formed at the apex of the protrusion, it is convenient to concentrate the liquid and pour it into a small-diameter container or the like when dispensing a small amount.

Further, since this small-diameter opening is formed by pulling and removing the small-diameter thin wall portion using a lift-up ring, the opening is easy and beautiful, and liquid such as physiological saline can be straightly discharged.

In addition, there are protrusions on the opposite sides of the slope of the conical top wall that you can hang your fingers on and twist. You can hang your finger on the protrusion at the same time.
A large-diameter opening can be easily opened by applying twisting force efficiently and uniformly to the annular thin wall portion. Furthermore, the protrusion on which the finger is placed fits in the virtual cylindrical space of the spout portion of the conical top wall, so that the protrusion does not get in the way.

Example Embodiments of the present invention will be described with reference to the drawings.

In the drawings, reference numeral 1 denotes a main body of a plastic container, at the upper end of which a spout 2 is formed in a protruding manner, and the spout 2 is sealed with a top wall 3. A male thread 4 is formed on the outer peripheral surface of the spout portion 2, and a lid body 6 having a female thread 5 formed on the inner surface is removably attached. The top wall 3 of the spout part 2 is raised upward in a conical shape with its central part as the apex, and the spout part 2 is surrounded by the raised top wall 3.
A thin plate-shaped annular thin portion 7 is formed along the edge of the mouth, and two plate-shaped protrusions 8 are formed on the raised surface at symmetrical positions with respect to the apex portion. These two protrusions 8 are used to twist and cut the portion of the ceiling wall 3 surrounded by the annular thin wall portion 7 by placing one's fingers on the two protrusions 8 and twisting them.

Further, a small-diameter thin wall portion 9 is formed at the apex portion of the central portion, and a lift-up ring 10 is connected to the outside of this small-diameter thin wall portion 9. The center part of the lift-up ring 10 is connected to the small diameter thin part 9, and the periphery is shaped like a finger ring.

In the plastic container configured as above, when the spout 2 is a small diameter opening,
When the lift-up ring 10 is pulled up as shown in FIG. 3, the small-diameter thin wall portion 9 is torn off, and that portion becomes a small-diameter opening. In addition, in order to make the spout part 2 a large-diameter opening, by hooking your fingers on the two protrusions 8 and twisting them, the part surrounded by the annular thin wall part 7 of the raised top wall 3 can be opened as shown in FIG. Twisted as shown,
The entire spout section 2 becomes a large-diameter opening. In this way, the large-diameter opening is formed by twisting and cutting the annular thin-walled part 7 in the form of a thin plate, so the edges are smooth without being uneven, and the liquid to be poured out is smooth. It flows out smoothly and does not scatter, especially when a large amount of liquid is poured out at once. Furthermore, since the small-diameter opening is located at the apex of the protrusion of the top wall 3, there is no scattering of the liquid when dispensing a small amount, making it convenient for pouring the liquid into small-diameter containers and the like.

In addition, since projections 8 on which the fingers can be twisted are formed at opposite positions of the slope of the conical top wall 3, when opening the large-diameter opening, the slope of the conical top wall 3 is The finger can be placed along the protrusion 8 along the hand, and the twisting force can be efficiently and evenly applied to the annular thin wall portion 7 to easily open the large diameter opening. Moreover, the protrusion 8 on which the finger is placed fits in the virtual cylindrical space of the spout portion of the conical top wall 3, and does not get in the way.

Further, according to the above embodiment, since the spout portion 2 has the top wall 3, even if the spout portion 2 is opened to a large diameter, it can be closed again with the lid 6, and the lid 6 can be prevented from being screwed on too much. Even if you open it by mistake, you will not be able to open it by mistake.

In addition to being configured as described above, the annular thin wall portion 7 may have a V-shaped groove formed inside the top wall 3.

Effects of the invention According to the invention, the spout at the upper end can be opened to either a small diameter or a large diameter, and when opening a large diameter, the spout can be opened by simply twisting the spout by hooking the finger on the protrusion. The opening operation is extremely easy,
Not only does the liquid not overflow, there are no irregularities on the large-diameter edge, and when the container is tilted to pour out the liquid, it can flow out smoothly, and the liquid does not scatter when pouring. A small-diameter opening is formed at the top of the bulge on the top wall, so that when dispensing a small amount, the liquid can be concentrated and easily and reliably poured into a small-diameter container or the like.

Furthermore, according to the present invention, by forming protrusions that can be twisted by hooking fingers on opposite positions of the slope of the conical top wall, when opening a large diameter opening, the slope of the conical top wall can be twisted. You can place your finger along the protrusion, apply twisting force efficiently and evenly to the thin annular part, and easily open a large diameter opening. By placing the liquid in the virtual cylindrical space of the pouring spout part of the top wall of the shape, an effect can be obtained in that that part does not get in the way.
