Description

  The present invention relates to a lid.

  A lid provided with a cylindrical portion for drinking is proposed (Japanese Patent Laid-Open No. 2006-160366, Japanese Patent Publication No. 2013-530888). For example, a lid for a beverage cup shown in FIGS. 6 to 9 has been proposed. 6 to 9, reference numeral 31 denotes a lid. 32 is a cylinder part (sucking part). The cylinder part 32 stands on the lid surface. 33 is an opening. The opening 33 is formed at the tip of the cylindrical portion 32. Reference numeral 34 denotes an arm portion. 35 is a stopper. The plug 35 is provided at the end of the arm portion 34. Reference numeral 36 denotes a recess.

  In the case where the lid having the above structure is attached to the container main body, the opening 33 is closed by the plug 35 even if the container is shaken. Therefore, the liquid in the container body does not leak outside.

  However, it has been found that various problems remain in the proposed lid.

  The lid 31 is obtained by punching the molded body along a solid line after a molded body (see FIG. 7 (plan view)) whose outer shape is indicated by a one-dot chain line is obtained. At this time, the material in the region between the solid line and the alternate long and short dash line is discarded. Many materials are wasted. Disposal cost is high. That is, the production cost is high.

  When drinking, the stopper 35 is located in the recess 36. Therefore, in patent document 1, it is said that the arm part 34 does not become obstructive at the time of drinking. However, the arm portion 34 is bent in a substantially C shape. The arm portion 34 is greatly curved on the upper surface of the lid. And the arm part 34 exists in the vicinity of the cylinder part 32 (refer FIG. 8). Therefore, the arm portion 34 is still an obstacle when drinking.

  When not drinking, the plug 35 is positioned in the opening 33 (see FIG. 9). As can be seen from the comparison between FIG. 9 and FIG. 8, the arm portion 34 is twisted by changing the angle greatly. As a result of the angle being greatly changed and twisted, there is a high possibility that the arm portion 34 is damaged.

  Furthermore, it takes time and effort to convert the state of FIG. 8 to the state of FIG. 9 and conversely to convert the state of FIG. 9 to the state of FIG. That is, handling (operability) is poor. In particular, those who are handicapped are difficult to handle.

  Therefore, the problem to be solved by the present invention is to solve the above problems. That is, it is to provide a lid that is low in cost, easy to handle, and highly durable.

  The first aspect of the present invention is a lid. A preferred embodiment of the lid is as follows. The lid includes a lid surface portion. The lid includes a cylindrical portion. The cylinder portion is erected on the lid surface portion. The cylinder part has an opening. The opening is provided at the tip of the cylindrical portion. The lid includes an arm portion. The lid includes a stopper. The plug portion is provided on the arm portion. The plug portion serves as a lid for the opening. One end of the arm portion is coupled to the peripheral edge A of the lid. The other end of the arm portion is coupled to the peripheral edge B of the lid. The peripheral edge A and the peripheral edge B are different positions.

  Preferably, the arm portion is configured such that the arm portion is latched to the peripheral edge portion when a pressing force that presses the arm portion downward from the peripheral edge portion is released.

  The arm portion is configured by forming a slit in the flange. For example, a flange is provided on the peripheral edge. A slit along a predetermined line is formed in the flange. Thereby, for example, an arc-shaped (bow-shaped) arm portion is formed. The slit is basically a line. The slit may have a slight width. Of course, the width may be very narrow. The width is generally 5 mm or less. For example, it is 2 mm or less. Preferably, it is 1 mm or less. The lower limit value of the width may be a value that enables slit formation. The slit can be formed by press working. The arm portion exists along a part of the peripheral edge of the lid. In forming the arm portion, a low ratio is wasted.

  The arm portion includes a wave shape portion, for example. The corrugated portion is preferably formed on the end side of the arm portion. Even if the deformation force acts on the arm portion, the strain acting on the arm portion is relieved by the presence of the wave shape portion. Accordingly, the durability of the arm portion is improved.

  The arm portion preferably has a spring function. The spring function is exhibited by the constituent material (for example, resin) of the arm portion and the shape (for example, arc shape (bow shape)) of the arm portion. By the spring function, the arm portion is effectively hooked on the peripheral edge portion. The hooked state is hard to come off naturally.

  The length of the arm part is preferably longer than the length of the half circumference of the lid peripheral part. When the lid is circular in plan view, a line connecting the center (position O) of the circle and one end (position A) of the arm portion, the center (position O) of the circle and the arm portion The crossing angle with the line connecting the other end (position B) is greater than 180 °. The angle formed by the line OA and the line OB is preferably more than 180 °. Accordingly, the arm portion is effectively hooked on the peripheral edge portion.

  The thickness of the tip portion of the cylindrical portion is preferably thinner than the thickness of the flat surface portion of the lid surface portion. As a result, the tip of the cylindrical portion becomes soft. That is, the tip portion of the cylindrical portion is so thin that it is soft. Therefore, the touch when the cylinder part is included in the mouth is good. The lid surface is thick. Therefore, the mechanical strength of the lid surface portion is high.

  The cylindrical portion is preferably a cylindrical portion having a multi-stage structure. For example, a two-stage cylinder. Alternatively, it is a three-stage cylinder. As a result, it is not necessary to unnecessarily lengthen the thin part (the part that is included in the mouth (the part that holds in the mouth)). Therefore, when the liquid (fluid: high-viscosity material) in the container is put into the mouth via the cylindrical portion, it is easy to drink. This is because it is easy to swallow a high-viscosity product (for example, a jelly-like product) through a soft and long straw because the straw collapses and cannot be swallowed. I understand. It is very easy to use when used by people with weak mouth muscles. For example, it is suitable for patients who have difficulty in swallowing and have primary diseases such as aging, cerebral infarction and Alzheimer. However, it is not limited to these patients.

  The cylindrical portion is preferably located at a position away from the lid center position.

  A recess is preferably formed in the lid surface portion. When the tube portion is used as a mouth, the tip of the nose is difficult to hit the lid due to the presence of the recess. In other words, when the cylindrical portion is used as a mouth, the concave portion is formed at a place where the nose is likely to hit the lid surface in order to avoid the nose. Because it is designed to avoid the nose, it is only necessary to tilt the cup without tilting the neck.

  The second present invention is a container. The container includes a container body. The container includes the lid. The opening of the container body is covered by the lid.

  Hereinafter, the present invention will be described with specific embodiments. However, the present invention is not limited to the following specific embodiments. Various modifications and applications are also included as long as the features of the present invention are not impaired.

  1-5 is explanatory drawing of the lid | cover used as one Embodiment of this invention. 1 is a perspective view of a container in a closed state, FIG. 2 is a perspective view of a container in a natural state after opening, FIG. 3 is a perspective view of the container in a drinking state (opened state), and FIG. 4 is a natural view after manufacturing. FIG. 5 is a sectional view of the lid in the state.

  In each figure, 1 is a container main body. The container body 1 is cylindrical. However, it may be a rectangular tube shape. An elliptic cylinder may be sufficient. Any shape is possible. There may be a scale on the inner surface where the volume can be confirmed. Hereinafter, the case of a typical cylindrical shape will be described. Since the container body has a cylindrical shape, the outer shape of the lid is substantially circular even in the following lid. The outer shape of the lid varies depending on the shape of the container body. Reference numeral 2 denotes an annular rib formed at the upper end of the container body 1. Any material can be used for the container body 1. For example, paper, resin, metal, etc. are mentioned. The resin may be opaque or translucent.

  3 is a lid. The lid 3 is for closing the upper end opening of the container body 1 (see FIG. 5). The material of the lid 3 is generally a resin. For example, olefinic resins such as polyethylene and polypropylene are listed. A soft resin is preferable to a hard resin. Olefin resins are preferred. When making it translucent, for example, a resin containing talc or the like is used. The resin may be opaque or translucent. The lid 3 can be obtained by molding the soft resin film (or sheet). An appropriate method can be adopted as the molding method.

  Reference numeral 4 denotes a lid surface portion (top surface portion). 5 is a cylinder part. The cylinder portion 5 is erected on the lid surface portion 4. Reference numeral 6 denotes an opening (hole). The opening (hole) 6 is formed at the upper end of the cylindrical portion 5. Reference numeral 7 denotes a peripheral side surface portion. Reference numeral 8 denotes a groove (fitting portion). The groove portion (fitting portion) 8 is formed at a boundary portion between the lid surface portion 4 and the peripheral side surface portion 7. When the lid 3 is attached to the container main body 1, the annular rib 2 of the container main body 1 is fitted into the groove portion (fitting portion) 8. As a result, the lid 3 is firmly held. Since these structures are also known from Patent Documents 1 and 2, detailed description thereof is omitted.

  The cylinder part 5 is a two-stage type in this embodiment. The diameter of the lower stage side cylinder part 5a is large. The lower cylinder portion 5a is low in height. The height is about 1 cm. Of course, it is not limited to this. The thickness of the lower cylinder portion 5a and the thickness of the lid surface portion 4 are approximately the same. The diameter of the upper cylinder portion 5b is small. When the mouth is used, the size is such that it does not feel resistance. The height of the upper stage side cylinder part 5b is higher than the height of the lower stage side cylinder part 5a. The height is about 1-2 cm. Of course, it is not limited to this. It is a length that does not give a sense of resistance when used in the mouth. When the length of the upper cylinder portion 5b is too short, it is difficult to include in the mouth. If the upper cylinder portion 5b is too long, or if the upper cylinder portion 5b is sucked, the upper cylinder portion 5b may be crushed. In particular, the thickness of the upper stage side cylinder part 5b is thinner than the thickness of the lower stage side cylinder part 5a. For example, it is about 0.2 to 0.5 mm. Of course, it is not limited to this. However, if compared with the thickness of the lid surface portion 4, the thickness of the upper cylinder portion 5b is thin. Therefore, the strength of the upper stage side cylinder part 5b is weak. However, the upper cylindrical portion 5b is soft as much as the thickness is small. It feels good when used in the mouth. The reason for providing the lower side cylinder part 5a is also because the length of the upper stage side cylinder part 5b is not increased. By providing the lower stage side cylinder part 5a, the length of the cylinder part 5 (the length of the lower stage side cylinder part 5a + the length of the upper stage side cylinder part 5b) becomes longer. Then, when the upper stage side cylinder part 5b is included in the mouth, the nose is less likely to hit the lid surface part 4 as much. In addition, it is not necessary to increase the length of the thin upper cylinder portion 5b.

  9 is a recess. The concave portion 9 is provided at an appropriate location on the lid surface portion 4. In particular, when the upper tube portion 5b is included in the mouth, the recess 9 is formed at a location where the nose is likely to be located. The nose is hard to hit the lid surface by the recess 9.

  Reference numeral 10 denotes an arm portion. The arm portion 10 has a bow shape (arc shape). One end portion of the arm portion 10 is connected to the peripheral edge portion A (left side portion A) of the lid 3. The other end of the arm 10 is connected to the peripheral edge B (right side B) of the lid 3. The arm unit 10 is configured as follows, for example. At the time of molding the lid 3, a flange 11 indicated by a one-dot chain line in FIG. After forming, press working is performed. Unnecessary portions of the flange 11 (a region sandwiched between the solid line and the alternate long and short dash line in FIG. 4) are removed by pressing. The slit 12 is formed by the press working. The arm part 10 is comprised by this press work. Waveform portions 13a and 13b are formed at both ends of the arm portion 10 during the press working. The uneven height of the corrugated portions 13 a and 13 b is about twice the thickness of the arm portion 10. For example, corrugated portions 13a and 13b having a height of about 1 mm are formed.

  Reference numeral 14 denotes a knob. The knob 14 is formed at the left and right center of the arm 10. 15 is an unevenness for preventing slipping. The irregularities 15 are formed on the front and back surfaces of the knob 14.

  16 is a stopper. The plug 16 closes the opening (hole) 6. The stopper 16 is provided in the arm portion 10 (location near the knob portion 14).

  The state immediately after the manufacturing of the lid is shown in FIG. At this stage, the arm part 10 is planar.

  A state in which the lid 3 is attached to the container body 1 and the stopper 16 closes the opening (hole) 6 is shown in FIG. In this state, the arm portion 10 is warped in a substantially C shape. Since the inside of the container is a sealed space, the fluid (fluid) in the container does not leak out.

  A state in which the stopper 16 is opened is shown in FIG. At the time of closing, the arm part 10 is substantially C-shaped (see FIG. 1). Therefore, even after opening, the arm portion 10 is warped somewhat. The arm portion 10 is located above the lid surface portion 4 (see FIG. 2). The arm portion 10 is deformed from a two-dimensional shape immediately after manufacture to a three-dimensional shape. In this state, when the upper cylinder portion 5b is included in the mouth, the arm portion 10 becomes an obstacle.

  Therefore, a downward force is applied to the arm unit 10. Of course, the force is then released. Then, since the arm portion 10 is deformed (see FIG. 2), the arm portion 10 is caught by the peripheral edge portion of the lid 3 (see FIG. 3). Therefore, in the state of FIG. 3, when the upper stage side cylinder part 5b is included in the mouth, the arm part 10 does not get in the way. The operation (work) from opening the plug 16 to including the upper cylinder portion 5b in the mouth is very simple. Compared with the lid of Patent Document 1, it is much simpler. Even for those who are handicapped, the above series of operations is extremely simple. For example, even if the hand is inconvenient due to obstacles or paralysis, the above series of operations is very simple. However, the present invention is not limited to this.
