  FIG. 1 is a perspective view showing a measuring container 1 according to the first embodiment of the present invention. The measuring container 1 is a medical beaker used for measuring liquids such as medicines and physiological saline. As shown in FIG. 2, a set of a plurality of disposable medical supplies prepared in accordance with the contents of medical treatment. Are included in the disposable medical supplies set 6. A disposable medical product set 6 shown in FIG. 2 includes a measuring container 1, a syringe 62, a drape 63, and a tray 61 having a substantially rectangular shape in plan view that accommodates these components. It is packed by. The disposable medical product set 6 may include other various medical products in place of the syringe 62 and the drape 63 shown in FIG. 2 or in addition to the syringe 62 and the like.

  As shown in FIG. 1, the measuring container 1 closes a substantially cylindrical side wall portion 11 centering on a predetermined central axis J <b> 1 and the lower end of the side wall portion 11 (that is, the lower end portion in FIG. 1). The spout 13 formed in the opening edge 113 which is the disk-shaped bottom part 12 and the upper end of the side wall part 11 is provided. The inner diameter and outer diameter of the side wall portion 11 are substantially constant in the direction of the central axis J1, and are slightly larger in the vicinity of the opening edge 113 of the side wall portion 11. The side wall portion 11 includes a rough surface portion 111 whose outer peripheral surface is a textured rough surface having minute unevenness, and a smooth surface portion 112 whose outer peripheral surface is a smooth surface. In FIG. 1, in order to facilitate understanding of the drawing, the rough surface portion 111 of the side wall portion 11 is shown with parallel oblique lines, and the boundary between the rough surface portion 111 and the smooth surface portion 112 is indicated by a two-dot chain line. Show.

  The side wall part 11, the bottom part 12 and the spout 13 of the measuring container 1 are made of a thermoplastic resin having high chemical resistance, and the minute irregularities formed on the outer peripheral surface of the rough surface part 111 of the side wall part 11 are At the time of forming the side wall part 11, the bottom part 12 and the spout 13 by injection molding of a plastic resin, it is formed by transferring minute irregularities formed on the mold. Polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), or the like is used as the thermoplastic resin forming the side wall portion 11, the bottom portion 12, and the spout 13, and in this embodiment, polypropylene is used. Thus, the side wall part 11, the bottom part 12 and the spout 13 are formed.

  In the measuring container 1, the entire inner peripheral surface of the side wall portion 11 and the entire upper surface of the bottom portion 12 (that is, the inner bottom surface of the measuring container 1) are smooth surfaces like the inner peripheral surface of the smooth surface portion 112. The smooth surface portion 112 is a transparent portion whose outer peripheral surface and inner peripheral surface are smooth surfaces. As shown in FIG. 1, since the volumetric scale is provided in the smooth surface part 112 of the side wall part 11, the smooth surface part 112 is called "scale part 112" in the following description. The scale portion 112 is provided in the vicinity of the spout 13 with respect to the circumferential direction centering on the central axis J1 in a plan view, and preferably provided within a range of 55 ° on each side of the circumferential direction from the spout 13. It is done. In the present embodiment, the scale portion 112 is provided within a range of 55 ° counterclockwise from the spout 13 when viewed from above along the central axis J1, and the maximum value of the volume scale of the scale portion 112. Is 500 ml (milliliter).

  In the measuring container 1, since the protruding portion that protrudes to the side and assists the holding of the measuring container is not provided on the side wall portion 11 such as a handle, the user holds the measuring container 1 from the spout 13 to the inside. When the liquid is poured into another container or the like, the portions of the side wall portion 11 that are 90 ° apart from the spout 13 on both sides in the circumferential direction around the central axis J1 (more precisely, this portion is included at least). Usually, the measuring container 1 is held while the finger of the hand is brought into contact with the outer peripheral surface of the part) via a glove. In the side wall portion 11 of the measuring container 1, portions that are 90 ° apart from the spout 13 on both sides in the circumferential direction are included in the rough surface portion 111, and when the measuring container 1 is gripped, the outer periphery of the rough surface portion 111 is Since the surface always comes into contact with the user's hand, the rough surface portion 111 is referred to as a “gripping portion 111” in the following description.

  In the present embodiment, the entire region of the outer peripheral surface of the side wall portion 11 excluding the outer peripheral surface of the scale portion 112 is a rough surface having minute irregularities. That is, all parts except the scale part 112 of the side wall part 11 become the grip part 111, and the grip part 111 becomes a translucent part or an opaque part that scatters light due to minute unevenness formed on the outer peripheral surface. Yes. The arithmetic average roughness Ra of the outer peripheral surface of the grip portion 111 is set to 2 μm (micrometer) or more and 4 μm or less, and in this embodiment, about 2.8 μm.

  As described above, in the measuring container 1, the substantially cylindrical side wall portion 11 is a rough surface having fine irregularities on the outer peripheral surface, and when the measuring container 1 is gripped by the user, the rough surface And a grip portion 111 that is in contact with the user's hand. In this way, by increasing the frictional resistance between the weighing container 1 and the user's hand using the outer peripheral surface of the gripper 111 as a rough surface, the weighing container 1 is prevented from slipping from the user's hand. The weighing container 1 can be reliably and easily gripped. In addition, the side wall 11 is provided with a transparent scale portion 112 having a smooth outer peripheral surface and a volume scale so that the liquid inside the measuring container 1 can be easily and clearly visually recognized through the scale portion 112. Therefore, when measuring while pouring liquid into the measuring container 1 or when pouring a predetermined amount of liquid from the measuring container 1 to another container while measuring the liquid, the accuracy of measurement is maintained. can do. Moreover, the color of the liquid in the measuring container 1 can also be visually recognized correctly.

  Since the measuring container 1 can easily hold the measuring container 1 by gripping the side wall portion 11 as described above, the structure of the measuring container 1 projects sideways like a handle or the like. It is particularly suitable for relatively small measuring containers that do not have a protruding part that assists the holding on the side wall, and is preferably applied to measuring containers having a maximum volume scale of 1000 ml or less (more preferably 750 ml or less). Is done. In addition, the structure of the measuring container 1 is particularly suitable for a measuring container used for medical purposes that is often held in a state where moisture such as blood or physiological saline is attached to the outer surface of the user's hand or side wall. ing. Thus, since the measuring container 1 can be preferably used as a relatively small measuring container for medical use, it is particularly suitable for a measuring container included in a disposable medical product set.

  In the measuring container 1, since the scale part 112 is provided in the vicinity of the spout 13 in the circumferential direction centering on the central axis J1, the scale part 112 is hidden by the user's hand in a state where the measuring container 1 is gripped. Is prevented. As a result, it is possible to accurately measure the liquid even when the measuring container 1 is held. Moreover, the scale part 112 is provided within a range of 55 ° from the spout 13 to both sides in the circumferential direction (that is, the scale part 112 is provided within a range of 110 ° centered on the spout 13 in the circumferential direction). In other words, the scale portion 112 is more reliably prevented from being hidden by the user's hand holding the measuring container 1, and the liquid is measured more accurately while the measuring container 1 is held.

  In the side wall part 11, all parts except the scale part 112 are gripping parts 111 (that is, parts where the outer peripheral surface is roughened), and a region that generates a relatively large frictional resistance with the user's hand. Is provided in a wide range on the outer peripheral surface of the side wall 11. For this reason, the freedom degree of how to hold the measuring container 1 can be improved.

  In the measuring container 1, the side wall part 11 and the bottom part 12 are formed of a thermoplastic resin, so that the measuring container 1 is compared with the case where the side wall part 11 and the bottom part 12 are formed of a material having a relatively large specific gravity such as glass. Is lighter. Thereby, the weighing container 1 can be further easily held. Moreover, the measuring container 1 which has high chemical resistance can be easily manufactured with a thermoplastic resin. Furthermore, by forming minute irregularities on the outer peripheral surface of the gripping part 111 by transferring the irregularities of the mold during the injection molding of the thermoplastic resin, the manufacturing of the measuring container 1 can be further simplified.

  In the side wall part 11, since the arithmetic average roughness Ra of the outer peripheral surface of the grip part 111 is 2 μm or more, the frictional resistance between the grip part 111 and the user's hand is sufficiently increased. 1 can be gripped more reliably. In addition, since the arithmetic average roughness Ra of the outer peripheral surface of the grip portion 111 is 4 μm or less, the side wall portion 11 and the bottom portion 12 can be easily released from the mold during injection molding, and the measuring container 1 can be manufactured. Further simplification can be achieved.

  Next, a measuring container according to the second embodiment of the present invention will be described. FIG. 3 is a perspective view showing a measuring container 1a according to the second embodiment. The measuring container 1a is a medical beaker used for measuring liquids such as medicines and physiological saline, like the measuring container 1 according to the first embodiment, and the disposable medical article set 6 (see FIG. 2). Included. As shown in FIG. 3, in the measuring container 1 a, the roughened range on the outer peripheral surface of the side wall part 11 (that is, the shape of the gripping part 111 a shown with parallel oblique lines) is the same as that of the measuring container 1 shown in FIG. 1. Is different. The other structure of the measuring container 1a is the same as that of the measuring container 1 shown in FIG. 1, and attaches | subjects the same code | symbol in the following description. In FIG. 3, in order to facilitate understanding of the drawing, each boundary between the gripping portion 111a, the smooth surface portion 112, and a side wall portion upper portion 114 described later is indicated by a two-dot chain line.

  As shown in FIG. 3, in the side wall part 11 of the measuring container 1a, the upper end of the grip part 111a whose outer peripheral surface is a rough surface having minute irregularities is below the opening edge 113 of the side wall part 11 (that is, the bottom part). 12 and the substantially cylindrical portion 114 between the upper end of the grip portion 111a and the opening edge 113 of the side wall portion 11 has a smooth outer peripheral surface and inner peripheral surface (that is, outer peripheral surface and inner peripheral surface). It is a transparent part. In the following description, the upper portion 114 of the side wall portion 11 is referred to as a “side wall portion upper portion 114”, and the grip portion 111 a and the scale portion 112 below the side wall portion upper portion 114 are collectively referred to as a “side wall portion lower portion 115”.

  In the side wall portion 11 of the measuring container 1a, in the portion excluding the side wall portion upper portion 114 (that is, the side wall portion lower portion 115), the circumferential direction around the central axis J1 from the pouring spout 13 is the same as in the first embodiment. Parts that are 90 ° apart on both sides are included in the grip portion 111a, and when the weighing container 1a is gripped, the outer peripheral surface (that is, the rough surface) of the grip portion 111a comes into contact with the user's hand. Thereby, it is prevented that the measuring container 1a slips from a user's hand, and the measuring container 1a can be hold | gripped reliably and easily. Further, by providing a transparent scale portion 112 having a volumetric scale at the side wall portion lower portion 115, the liquid inside the measuring container 1 can be easily and clearly defined via the scale portion 112, as in the first embodiment. Since it can be visually recognized, the accuracy of weighing can be maintained.

  In the measuring container 1a, in particular, when the substantially cylindrical side wall portion upper portion 114 is a transparent portion, when a large amount of liquid is held in the measuring container 1a, the liquid level is changed via the side wall portion upper portion 114. It can be easily visually recognized. For this reason, when the measuring container 1a is moved, it is possible to grasp how the liquid in the measuring container 1a shakes, and it is possible to prevent the liquid from spilling beyond the opening edge 113 of the side wall portion 11.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

  For example, the inner diameter and the outer diameter of the side wall 11 of the weighing container according to the above-described embodiment do not necessarily have to be substantially constant with respect to the direction of the central axis J1. The outer diameter may be gradually increased.

  In the side wall part 11 of the measuring container, for example, as long as the grip part includes at least 90 ° parts on both sides in the circumferential direction from the spout 13, for example, the outer peripheral surface of the part near the bottom 12 of the side wall part 11. May be a smooth surface over the entire circumference, and the cylindrical portion may be a transparent portion. Even in this case, when the weighing container is gripped, the measuring container can be reliably and easily maintained while maintaining the accuracy of weighing by bringing the user's hand into contact with the outer peripheral surface of the gripping portion which is a rough surface. It can be gripped.

  In the measuring container, the side wall part 11, the bottom part 12, and the spout 13 need not be formed of a thermoplastic resin, and may be formed of a material having translucency such as glass, for example. In this case, the minute unevenness provided on the outer peripheral surface of the grip portion of the side wall portion 11 is formed by various methods suitable for the material, such as sandblasting.

  The above-described measuring container does not necessarily need to be included in the disposable medical supplies set, and may be prepared alone and used for medical purposes in a medical facility such as an operating room. Moreover, the structure of the above-mentioned measuring container may be applied to various medical measuring containers other than medical beakers, or measuring containers used for non-medical purposes. Furthermore, a measuring container having the above-described structure that is manufactured for use in applications other than medical treatment may be used as a medical component as a component of a disposable medical product set.

It is a perspective view of the measuring container which concerns on 1st Embodiment. It is a top view of a disposable medical supplies set. It is a perspective view of the measuring container which concerns on 2nd Embodiment.
