Description

  The present invention includes liquid beverages such as milk, juice, coffee, and tea, liquid foods such as soy sauce, sauce, and vinegar, and other liquids such as enteral nutrients (hereinafter collectively referred to as “fluid”). In connection with a straw that is detachably inserted into a press-deformable container (hereinafter also referred to as “container”) such as a paper pack in which the fluid is stored, and used to pour the fluid out of the container, in particular, The present invention relates to a straw that can easily pour out the fluid in the container up to the last drop and can easily pump and pour out the fluid to a desired place by connecting a straw outlet to another transfer pipe.

    Conventionally, a straw is detachably inserted into a straw insertion hole of a container such as a paper pack or an aluminum pouch having a straw insertion hole, and a liquid beverage is taken into the oral cavity through the straw. In this way, when the liquid beverage contained in the paper pack is transferred to another container such as a plate or cup, the straw may fall out of the paper pack during pouring, or the liquid beverage in the container It was necessary to adjust the length of the inserted straw in the paper pack, and it was difficult to pour out the last drop of liquid beverage as it was.

  Therefore, as a technique for solving these problems, a locking portion for preventing the dropout from the paper pack is provided along the outer periphery of the straw, and the liquid beverage in the paper pack is provided on the straw body in the vicinity of the locking portion. Patent Documents 1 and 2 propose a straw having a through hole through which the water can flow into the straw.

  However, the straw described in the above-mentioned patent document follows the shape in which the tip of the straw enters deeply into the paper pack like a conventional straw, and has a shape in which a through hole is added in the vicinity of the locking portion of the straw. For this reason, depending on the material of the straw, the thickness of the tube wall, and the like, when inserting into the straw insertion hole of the paper pack, the portion of the straw body that has the through hole may be bent, making insertion difficult.

  In addition, when the fluid is poured out by pressing the paper pack, the fluid remains in the body of the straw inserted deeply into the paper pack, and it is difficult to perform the dispensing operation by completely removing the fluid. there were. Furthermore, there is a problem that the straw body in the inner side of the paper pack having a longer length and having a through hole in the body portion has a high material cost and takes time and effort.

  By the way, in recent years, along with advances in medical and nursing care technology, liquid medicines and liquid foods of pharmaceuticals have been administered directly to the nasal cavity and gastrointestinal tract of the sick and elderly from the outside. Since administration has been performed not only in hospitals but also at homes and nursing homes, development of simple and accurate administration methods that can be performed even by amateurs is desired.

  The present invention has been made in view of the above-described various problems and demands. When the straw is inserted into the straw insertion hole of the paper pack, the straw is difficult to bend and the fluid in the paper pack is poured out. In some cases, it is an object of the present invention to provide a straw that has a shape in which no fluid remains in the straw body, and that has reduced material costs and processing costs.

That is, the straw of the present invention is
A straw that can be pressed and deformed and has a straw insertion hole, and is detachably inserted into the straw insertion hole of a container that can store a fluid, and the straw is inserted into the straw insertion hole after the straw is inserted into the straw insertion hole. In the straw in which an annular band is provided along the outer periphery of the straw as an engaging part for preventing the pulling, the container inner part in the immediate vicinity of the annular band of the straw is separated from one side of the straw circumference. It cuts substantially diagonally to the side, and is formed as a flat-tip-shaped opening having a tip on the other side of the body circumference, and the opening serves as a suction port for the fluid.
By adopting such a structure, the fluid contained in the press-deformable container is all sucked from the pointed opening of the straw inserted into the container and pushed out of the container by pressing the container.

  That is, since there is no portion corresponding to the body part of the conventional straw in the container, the fluid does not remain in the body part. At this time, if the cross section cut obliquely is made into at least two or more oblique cross sections formed with different cut angles, the suction port can be formed widely and the straw tip is strong against the straw insertion hole of the container. It becomes difficult to bend and can be inserted smoothly.

  Also, the end of the straw outside the container after being inserted into the straw insertion hole serves as a spout for the fluid formed by tapering the body of the straw toward the tip side. When pouring out to a desired position separated from the tube, this can be easily achieved by inserting and connecting to the other end of the conduit having one end disposed at the separated position. At this time, a part of the body portion of the straw outside the container extending in the longitudinal direction has a bendable bellows structure, so that the work of inserting and connecting can be further facilitated.

  The straw of the present invention is provided with an engaging portion on the outer periphery of the straw so that the straw does not fall out from the straw insertion hole of the container as described above, and the straw body portion inside the container in the immediate vicinity of the engaging portion is inclined. Since it has a structure in which it is cut and opened, and the opening is used as a fluid suction port, that is, there is no body portion in which the fluid remains like a conventional straw inside the container, so that it can be pressed and deformed. All the fluid contained in the container can be poured out of the container from the outlet of the straw through the suction port of the straw by pressing the container.

  Further, since the suction port of the straw has an oblique cross section formed with different cutting angles, the pointed end of the straw is strong and difficult to bend, and the insertion into the container can be performed more smoothly. In addition, the straw outlet is tapered and part of the body is foldable, making it easier to fit and connect the straw to a conduit, etc. Can be transported.

  Hereinafter, the straw of the present invention will be described with reference to the embodiments shown in the drawings.

  FIG. 1 is a perspective explanatory view showing one embodiment of a state in which a straw of the present invention is accommodated in a transparent bag attached to an outer surface of a container containing a fluid, and FIG. 2 is a perspective view of the straw of the present invention. It is plane explanatory drawing which shows one Example of the state inserted even to the latching | locking part of the straw in the insertion hole of the container. FIG. 3 is a cross-sectional view showing an embodiment of a state in which a straw is inserted into the insertion hole of the container and is prevented from falling out of the container by the locking portion of the straw, and FIG. 4 is a view of the vicinity of the suction port according to the present invention. The principal part expanded side sectional view which shows one Example, FIG. 5: is the principal part enlarged side sectional view which shows the other Example of suction port vicinity similarly.

  As shown in FIG. 2, the straw 3 of the present embodiment has a hollow elongated cylindrical shape with a total length of 60 mm and a body diameter of 6 mm, and has a channel extending in the longitudinal direction in the same manner as a normal straw, The part is opened and formed as a suction port 5 and a spout 6, respectively. The end on the suction port 5 side is cut obliquely and sharp, and the spout 6 is formed as an opening formed with the barrel 7 tapering 10.

  In addition, an annular band is projected along the outer periphery of the straw 3 in the immediate vicinity of the suction port 5, and the outer diameter of this portion is a large diameter of about 7 mm. Further, a predetermined area substantially in the middle of the straw 3 is formed as a bellows structure 8, and the spout 6 can be directed in an arbitrary direction while the straw 3 is inserted into the container 2.

  The straw 3 of this embodiment is made of soft polyethylene, but is not limited to this, and may be made of other resin. The straw 3 manufactured as described above is, for example, a container (paper pack) capable of being deformed by pressing and containing a fluid (A) such as milk and juice and having a straw insertion hole 2 as shown in FIGS. 1 is used by being inserted into the straw insertion hole 2. At this time, the straw 3 is accommodated in a transparent straw storage bag 9 and attached to the outer wall of the container 1 for use with the container 1.

  Such a container 1 with a straw is generally used because the inside of the straw insertion hole 2 is covered with a synthetic resin film 11 and the outside is sealed with an aluminum foil (not shown) or the like. At that time, the straw 3 is inserted into the container 1 by peeling or breaking through the aluminum foil. The same container is used in this embodiment.

Next, the operation of this embodiment will be described.
First, an aluminum foil (not shown) that seals the outside of the straw insertion hole 2 of the container (paper pack) 1 is peeled off or is broken through as it is, and is made of a synthetic resin that covers the inside of the straw insertion hole 2. The sharply formed end portion 12 of the suction port 5 of the straw 3 is pressed against the film (sheet) 11 (see FIGS. 4 and 5) to cleave the synthetic resin film 11 and the engaging portion 4 of the straw 3 is the container. The straw 3 is inserted into the container 1 until it is inserted into the container 1.

  Thus, after inserting the straw 3 in the straw insertion hole 2, as shown in FIG. 3, the paper pack 1 is inverted and the spout 6 of the straw 3 is faced downward. At this time, the outer peripheral wall of the straw 3 in the vicinity of the straw insertion hole 2 is surrounded by the inner peripheral wall of the straw insertion hole 2 and the synthetic resin 11 and is held liquid-tight. In addition to this, the straw 3 does not fall out of the straw insertion hole 2 due to the locking action of the locking portion 4.

This is because the fluid A in the paper pack 1 is poured out from the spout 6 through the suction port 5 of the straw 3 by its own weight, or both sides of the paper pack 1 are pressed with fingertips, and the paper pack 1 is deformed. In the case where the fluid is poured by pressing or crushing, the same action is performed, and the straw 3 does not fall off. Moreover, since the straw 3 of the present embodiment has the spout 6 formed in a tapered shape, and the middle of the body on the spout 6 side has a bellows structure, the spout of the straw 3 is connected to another conduit (not shown). The fluid A in the paper pack 1 can be pumped to a desired place by being inserted and connected.
In addition, in the straw of this invention, you may provide one latching | locking part and may provide another place across the material of the container. By doing so, excessive piercing can be prevented.

  Needless to say that it can be used as a straw for pouring out of paper packs containing liquid drinks such as milk and juice, as well as paper packs containing medicines, enteral nutrients, etc. By using the straw and conduit of the present invention to the caregiver's nasal cavity, gastrointestinal tract, and the like, it is possible to supply directly by direct pumping.
