Description

The present invention relates to a cover of a cup containing urine, and relates to preventing urine from leaking from the cup during transportation. The present invention also relates to a method for attaching a cup cover.

  In hospitals, medical institutions, inspection institutions, etc., cups containing urine are transported. For this purpose, a cover (lid) for preventing leakage from the cup is required, and the inventors have proposed fixing the lid to the cup with an elastic ring (Patent Document 1: Japanese Patent Laid-Open No. 2009-23836). In Patent Document 1, the lid includes a groove that engages with the edge of the cup, and the cross section of the lid protrudes upward in an inverted U shape at the groove portion. Then, the lid is put on the cup, and the protruding portion of the lid is sandwiched between the elastic rings to eliminate the gap between the edge of the cup and the protruding portion of the lid. However, it has been found that this method requires a long time to attach and detach the elastic ring and has a problem in operability.

JP2009-23836

  An object of the present invention is to make it easier to attach and detach a cup cover.

This invention is a circular and elastic cup cover to be a lid of a cup containing urine,
It consists of a circular upper layer sheet, a circular lower layer sheet that adheres concentrically to the upper layer sheet on the lower surface of the upper layer sheet and projects downward from the upper layer sheet,
The upper layer sheet and the lower layer sheet are both made of foamed synthetic resin with closed pores,
The lower sheet is smaller in diameter and thicker than the upper sheet,
The portion of the upper layer sheet that is not covered by the lower layer sheet constitutes a flange that covers the edge of the cup opening,
The side surface of the lower layer sheet is a cylindrical surface , and constitutes a contact portion in contact with the inner surface of the opening of the cup,
The flange is pressed against the edge of the cup opening with the contact portion facing downward, and the contact portion is pushed into the cup, whereby the cup cover is curved downward and the contact portion is compressed in the radial direction. It is configured to be attached to a cup.

The present invention is also a method of attaching a circular and elastic cup cover to a cup containing urine,
The cup cover is composed of a circular upper layer sheet, and a circular lower layer sheet that adheres concentrically to the upper layer sheet on the lower surface of the upper layer sheet and protrudes downward from the upper layer sheet. Both the upper layer sheet and the lower layer sheet are foamed with closed pores. Made of synthetic resin, the lower layer sheet is smaller in diameter and thicker than the upper layer sheet, and the portion not covered by the lower layer sheet on the lower surface of the upper layer sheet constitutes a flange portion that covers the edge of the cup opening, The side surface is a cylindrical surface , and constitutes a contact portion in contact with the inner surface of the cup opening,
The flange of the cup cover is pressed against the edge of the cup opening with the contact portion facing downward, and the contact portion is pushed into the cup, thereby curving the cup cover downward and making the contact portion in the radial direction. And a cup cover is attached to the cup.

  In the present invention, when the flange portion of the cup cover is pressed against the edge of the cup, the cup cover is bent downward and the contact portion is compressed in the radial direction. Since the cup cover is bent downward and the contact portion is compressed, the contact portion is in close contact with the inner surface of the cup and cannot be detached from the cup. In this way, the cup cover can be attached to the cup simply by pressing the cup cover against the cup with a palm or the like.

The cup cover is made of a foamed synthetic resin having closed pores, and the cup cover is elastic and water-repellent, so that the contact portion is in close contact with the inner surface of the cup and urine does not leak from between the cup and the contact portion.

The cup cover is composed of a circular upper layer sheet and a circular lower layer sheet that is bonded to the lower surface of the upper layer sheet concentrically with the upper layer sheet. Both the upper layer sheet and the lower layer sheet are made of foamed synthetic resin having closed pores, and the lower layer sheet is smaller in diameter and thicker than the upper layer sheet. A portion of the lower surface of the upper layer sheet that is not covered with the lower layer sheet constitutes the flange portion, and a cylindrical surface on the side surface of the lower layer sheet constitutes the contact portion. If the cup cover is foamed with a mold or the like, a mold release agent is required. The mold release agent dissolves the surface of the foamed synthetic resin, the bubbles on the surface are crushed, and the elasticity is lowered and the water repellency is also lowered. Therefore, if the upper layer sheet and the lower layer sheet are bonded to the same core instead of using a mold, the water repellency inherent to the foamed resin is not lost, and the bubbles near the surface are not crushed.

To make a cup cover,
Cutting out a circular upper layer sheet from the first sheet of foamed synthetic resin,
Cut out a lower layer sheet having a diameter smaller than that of the upper layer sheet from the second sheet that is made of foamed synthetic resin and is thicker than the first sheet,
The upper layer sheet and the lower layer sheet are bonded concentrically.

  In the following, an optimum embodiment for carrying out the present invention will be shown. The examples do not limit the scope of the present invention, and can be freely changed within the scope of the known art.

  FIGS. 1-6 shows the cup cover 2 of an Example and its usage. As shown in FIG. 1 and FIG. 2, the cup cover 2 of the embodiment has two layers of a circular upper layer sheet 6 that is concentric with a circular lower layer sheet 4 and has no holes in a plan view. The flange portion 7 on the outer periphery of the upper layer sheet 6 covers the upper edge 16 of the paper cup 10 in FIG. 3, and the lower layer sheet 4 protrudes vertically downward from the inner peripheral surface of the flange portion 7. Is in liquid-tight contact with the inner surface 14 of the paper cup 10 (FIG. 3). 9 is a center part inside the contact part 8, the lower layer sheet | seat 4 and the upper layer sheet | seat 6 are adhere | attached, it is circular and there is no hole. A part of the central portion 9 may be made of an elastic material such as paper or a synthetic resin film. In this specification, directions such as up and down are defined based on the use of the cover 2. The paper cup 10 is for urinalysis, and may be a cup made of another material such as a synthetic resin film or a foamed synthetic resin.

The material of the cup cover 2 will be described. The lower layer sheet 4 and the upper layer sheet 6 are both made of foamed plastic with closed pores, and the lower layer sheet 4 and the upper layer sheet 6 may be made of the same material or different materials, for example, made of foamed polyethylene, foamed polyurethane, etc. For example, it is about 0.02 to 0.04 g / cm ³ . The lower layer sheet 4 is thicker and smaller in diameter than the upper layer sheet 6, and is bonded to the upper layer sheet 6 with an adhesive (not shown) concentrically. No adhesive or pressure-sensitive adhesive is applied to the surface of the cover 2, and the foamed synthetic resin of the fabric is rough exposed on the surface.

  An example of the size of the cover 2 will be described. For example, the outer diameter of the target paper cup 10 is 80 mm, the outer diameter of the cover 2 (the outer diameter of the upper layer sheet 6) is approximately 80 mm, and the outer diameter of the lower layer sheet 4 is, for example, 70 to 72 mm. The outer diameter of the lower layer sheet 4 is the same as or slightly larger than the outer diameter of the opening 11 (FIG. 3) of the paper cup 10. The thicknesses of the sheets 4 and 6 are, for example, 1 to 3 mm for the upper sheet 6 and 2 mm here, and 3 to 10 mm for the lower sheet 4 and 5 mm here. These sizes are examples, and can be changed as appropriate according to the size of the cup 10 and the elasticity of the lower layer sheet 4.

  FIG. 3 shows the attachment of the cover 2 to the paper cup 10 containing the urine 12. Reference numeral 12 denotes urine, which is a test sample, 11 is an opening of the cup, 14 is an inner surface of the cup 10, and 16 is an upper ring-shaped edge. The cup 10 is laminated with a synthetic resin film on the inner side surface 14 or the like, or is provided with a hydrophobic layer.

  When the cup cover 2 is pressed against the paper cup 10 with a palm or the like with the lower layer sheet 4 facing down, the flange portion 7 hits the edge 16 of the cup 10 and the lower sheet 4 is pushed into the cup 10. At this time, as shown by the broken line in FIG. 3, the cup cover 2 is slightly curved downward, and the contact portion 8 is pushed into the paper cup and compressed in the radial direction. For this reason, the contact portion 8 of the cup cover 2 is pushed into and closely adhered to the inner side surface 14, whereby the cup cover 2 is attached to the cup 10. Further, since both the inner side surface 14 and the contact portion 8 of the cup 10 are hydrophobic or water repellent, liquid leakage does not occur.

  When the transport of the cup is completed and the cover 2 is removed, it is preferable to insert a finger or the like into the gap 18 between the edge 16 and the flange portion 7. In addition, you may attach a tab etc. to the upper sheet | seat 6 in the range which does not prevent closing the cover 24 of case 22 (FIG. 4, FIG. 5) mentioned later. Further, in this specification, the term “circular” includes not only a perfect circle but also a tab or the like attached to it, or a part that is slightly out of the perfect circle and close to an ellipse. The cover 2 of the embodiment does not contaminate the urine 12 because there is no layer such as a release agent or an adhesive on the surface. Further, since it is water repellent, urine does not penetrate into the cover 2 and can be reused by ultrasonic cleaning in water.

  4 and 5 show an example in which the cup 10 covered with the cover 2 is accommodated in the inner case 20 of the pneumatic carrier (not shown). 22 is an individual case, 24 is a lid, and an elastic sheet 26 is provided on the inner surface. Reference numeral 28 denotes a recess, and reference numeral 30 denotes a protrusion. The cup 10 is set as shown in FIG. 5, the lid 24 is closed, and the protrusion 30 is locked by the recess 28. When the direction of the air carrier changes during conveyance, for example, when it is turned upside down, the cover 2 is supported by the elastic sheet 26. When transported by an air feed, there are cases where the top and bottom are reversed during the transport, lie down, and move vertically up and down. At this time, the elastic sheet 26 supported the cover 2 and it was found by experiment that no liquid leakage occurred.

  The transport of the cup 10 is not limited to the pneumatic carrier, and a case 60 shown in FIG. 6 can be used. 62 is a lower case, 64 is an upper case, 65 is an elastic sheet, and the cup 10 is accommodated in the hole 66. The upper case 64 and the lower case 62 are closed. Then, the case 60 is conveyed by a pneumatically operated automatic guided vehicle or the like.

  In order to manufacture the cup cover 2, a thin first sheet made of a closed-pore foamed resin and a thick second sheet made of a closed-pore foamed resin are prepared, and the upper layer is formed by punching, cutting or the like. 6 and lower layer 4 are cut out. Here, the lower layer 4 has a smaller diameter than the upper layer 6. An adhesive is applied to the lower layer 4, and the upper layer 6 and the same core are overlapped and bonded. No other pressure-sensitive adhesive or adhesive is used for the cup cover 2. In this way, the cup cover 2 can be manufactured without a release agent.

In the example and the modification, the following effects can be obtained.
1) By simply pressing the flange portion 7 against the edge 16 of the cup 10, the cover 2 can be attached and leakage can be prevented.
2) The cover 2 can be removed from the gap 18 between the flange portion 7 and the edge 16.
3) Since the cover 2 is water-repellent, it is not contaminated with urine and can be reused.
4) Cups can be automatically transported by air-feeder without urine leaking.
