Description

  In this device, an annular elastic locking body having a large radial width with respect to the thickness is attached to the outer peripheral side surface of the lid, and this annular elastic locking body is crimped while being elastically deformed to the inner peripheral side surface of the opening portion of the drinking container. In particular, it relates to a drinking container with a lid so that the lid is not easily removed from the drinking container, and in particular, the inner peripheral side surface of the opening part of the drinking container to which the annular elastic locking body of the lid is crimped is directed obliquely upward. The present invention relates to a drinking container with a lid which is formed so as to be inclined to prevent the lid from being easily removed due to the elastic return of an annular elastic locking body.

An annular elastic locking body having a large radial width with respect to the thickness is attached to the outer peripheral side surface of the lid, and the annular elastic locking body is crimped while being elastically deformed to the inner peripheral side surface of the opening portion of the drinking container. 2. Description of the Related Art A lidded drinking container that is not easily removed from a drinking container is known.
This drinking container with a lid is attached even if the drinking container with a lid is tilted or tilted by an annular elastic locking body attached to the outer circumferential side surface of the lid being crimped to the inner circumferential side surface of the drinking container while being elastically deformed. The lid is not easily removed, and the liquid in the drinking container is prevented from leaking or overflowing.
When the lid is attached to the opening of the drinking container, the annular elastic locking body having a large radial width with respect to the thickness attached to the outer peripheral side surface of the lid has an outer peripheral edge on the inside of the opening part of the drinking container. Crimping is performed in contact with the peripheral side surface and elastically deforming obliquely upward.
On the other hand, the inner peripheral side surface of the opening part of the drinking container to which the lid is attached is inclined or rounded toward the outer peripheral side toward the upper surface. That is, the inner diameter of the inner peripheral side surface of the opening portion of the drinking container has a structure that slightly expands upward.
In addition, in a drinking container with a lid, if you drink the liquid inside without closing the lid, the lid that closes the opening of the drinking container makes it difficult to cool if the liquid inside is hot, On the contrary, when the internal liquid is cold, there are advantages such as being difficult to warm and preventing the internal liquid from overflowing from the opening. For this reason, it is conceivable that a spout is formed in a part of the lid, and a straw is inserted into the spout so that the liquid inside can be drunk while the lid is attached.

However, as shown in FIG. 8, the annular elastic locking body 104a of the lid 103a that is crimped to the inner peripheral side surface 102 of the opening portion of the drinking container 101 has a force to elastically return to the original state. Always acts, and this elastic restoring force acts to push the annular elastic locking body upward. Further, the inner peripheral side surface 102 of the opening portion of the conventional drinking container 101 to which the lid is attached as described above is inclined or rounded toward the outer peripheral side toward the upper side, and the inner diameter slightly increases toward the upper side. It has a structure that opens.
Therefore, when the inner peripheral side surface 102 of the drinking container 101 is moistened by the liquid contained in the container, the annular elastic engagement between the inner peripheral side surface 102 of the opening portion of the drinking container 101 and the lid 103a that is crimped to the inner peripheral side surface 102 is provided. The frictional resistance of the contact surface with the stop body 104a becomes small and it becomes easy to slide, and the annular elastic locking body 104b is moved upward by the upward force always acting on the annular elastic locking body, and the annular movement is moved upward. The elastic latching body 104b pushes up the lid 103b on which the annular elastic latching body 104b is mounted, and the annular elastic latching body 104c of the lid 103c that has been crimped to the inner peripheral side surface 102 of the opening portion of the drinking container 101 is crimped. The state is released.
As a result, when the drinking container tilts or falls, the lid that closed the opening of the drinking container is easily removed, and the liquid inside leaks or overflows, causing the surroundings to become dirty. .
In addition, if the inside of the drinking container is closed with a lid and the inside liquid is directly put into the spout without using a straw, the nose hits the surface of the lid and it is difficult to drink. .

  The present invention has been devised in view of the problems as described above, and has been devised in order to solve the problems. The object of the present invention is to provide an inside of the opening portion of the drinking container to which the annular elastic locking body of the lid is crimped. An object of the present invention is to provide a drinking container that is formed by tilting the peripheral side surface obliquely upward toward the inner side and preventing the lid from being easily removed due to the elastic return of the annular elastic locking body. Another object is to use a drinking container that keeps the opening of the drinking container closed with a lid and makes it easy to drink without drinking the nose against the surface of the lid. It is to provide.

  In order to achieve the above object, the invention of claim 1 is provided with an annular elastic locking body having a large radial width with respect to the thickness attached to the outer peripheral side surface of the lid, and the annular elastic locking body is used for a drinking container. In a drinking container with a lid that is crimped while elastically deforming to the inner peripheral side surface of the opening part so that the lid is not easily detached from the drinking container, the inner circumference of the opening part of the drinking container to which the annular elastic locking body of the lid is crimped It is composed of means formed by tilting the side surface obliquely upward toward the inner side.

  Further, in the invention of claim 2, an annular elastic locking body having a large radial width with respect to the thickness is attached to the outer peripheral side surface of the lid, and this annular elastic locking body is attached to the inner peripheral side surface of the opening portion of the drinking container. In a drinking container with a lid that is crimped while being elastically deformed so that the lid is not easily detached from the drinking container, the inner peripheral side surface of the opening part of the drinking container to which the annular elastic locking body of the lid is crimped is directed toward the inside. It is formed by slanting upward and forming a means in which the surface side of the lid is formed into a concave curved surface, and a spout is formed in a part of the peripheral side of the concave curved surface of the lid surface.

  Further, in the invention of claim 3, an annular elastic locking body having a large radial width with respect to the thickness is attached to the outer peripheral side surface of the lid, and this annular elastic locking body is attached to the inner peripheral side surface of the opening portion of the drinking container. In a drinking container with a lid that is crimped while being elastically deformed so that the lid is not easily detached from the drinking container, the inner peripheral side surface of the opening part of the drinking container to which the annular elastic locking body of the lid is crimped is directed toward the inside. Inclined upward and formed, the lid surface side is formed into a concave curved surface, a spout is formed at a part of the peripheral surface side of the concave surface of the lid surface, on the outer peripheral side surface of the intermediate portion in the height direction of the lid A flange that protrudes over the entire circumference protrudes, a mounting groove for mounting the annular elastic locking body is formed over the entire circumference on the outer circumferential surface of the lid below the collar, and the upper outer circumferential surface of the lid above the collar Is formed in a concave curved surface shape whose diameter decreases toward the upper side, and the outer peripheral side of the drinking container Those made of means provided with a handle on.

  As is clear from the above description, according to the drinking container with a lid according to the invention of claims 1 to 3, the inner peripheral side surface of the drinking container is dampened by being wetted by the liquid contained in the container. The frictional resistance of the contact surface between the inner peripheral side surface of the opening portion of the container and the annular elastic locking body of the lid that is pressure-bonded to the inner peripheral side surface becomes small and slippery, and the inner peripheral side surface of the opening portion of the drinking container It acts to push up the annular elastic locking body upwards by the elastic restoring force that tries to elastically return to the original state that always acts on the annular elastic locking body of the lid that is crimped between them. An inner peripheral side surface formed by inclining upwardly the force to push up the annular elastic locking body by forming the inner peripheral side surface of the opening part of the drinking container to which the body is crimped inclined obliquely upward toward the inner side Can be prevented. Thereby, it is possible to prevent the lid from easily coming off naturally due to the elastic return of the annular elastic locking body, and even if the drinking container is tilted or falls, the lid that has blocked the opening of the drinking container can be easily obtained. The liquid inside does not leak and overflow, and the surrounding area is not contaminated with the liquid that leaks or overflows.

  Moreover, according to the drinking container with a lid which concerns on the device of Claims 2-3, in addition to the said effect, the surface side of a lid is formed in a concave curved surface, and a spout is formed in a part of the peripheral side of the lid surface As a result, the lid side is formed with a concave curved surface when the liquid inside is directly covered with the mouth attached to the spout while the opening of the drinking container is closed with the lid. Can be prevented from hitting the surface of the lid, the disadvantage that it becomes difficult to drink by opening the mouth to the spout by hitting the nose hits the lid surface, the advantage of drinking by closing the opening of the drinking container with the lid In other words, it is difficult to cool when the internal liquid is hot, and conversely, when the internal liquid is cold, it is difficult to warm, and the internal liquid is less likely to overflow from the opening. You can enjoy the advantages of being difficult to enter. Moreover, even if the drinking container is tilted vigorously, the liquid inside does not overflow and enter the nose. In addition, when the mouth is directly attached to the spout, the upper lip and the surface side of the lid are also formed with a concave curved surface, which makes it easier to press, making it easier to drink and eliminating the gap between the upper lip when drinking It can be made difficult to overflow from there. Because of these advantages, it is suitable for use by sick people. That is, the liquid in the drinking container cannot be drunk at a time like a sick person, and it is suitable for a person who drinks little by little over time because it has good heat retention and is less likely to contain dust.

  Further, according to the drinking container with a lid according to the invention of claim 3, in addition to the above-described effect, by forming a protruding piece protruding over the entire circumference on the outer peripheral side surface of the intermediate portion in the height direction of the lid, The hook piece functions as a stopper, and the lid can be prevented from being pushed into the drinking container more than necessary. In addition, since the mounting groove for mounting the annular elastic locking body is formed on the outer peripheral side surface of the lid below the flange piece over the entire circumference, the annular elastic locking body can be securely mounted on the outer peripheral side surface of the lid. . In addition, the upper lip of the lid on the upper side of the collar piece is formed in a concave curved surface shape whose diameter decreases toward the upper side, so that the lower lip is the upper portion of the concave curved surface when the mouth is directly attached to the spout. It becomes easy to press against the outer peripheral side surface, and it becomes easy to drink and at the time of drinking, there is no gap between the lower lip and it is difficult to overflow from there. Furthermore, by providing a handle on the outer peripheral side of the drinking container, it is possible to easily drink by grasping the handle with one hand. You won't get burned or accidentally drop the drinking container by releasing your hand because it was too hot. In addition, when the opening of the drinking container is closed with a lid, there is an extremely practical and beneficial effect such that the liquid inside does not overflow even if the drinking container is tilted vigorously by grasping the handle with one hand. It is.

Hereinafter, the present invention will be described more specifically based on the best mode for carrying out the invention described in the drawings.
1 is a perspective view of a drinking container with a lid, FIG. 2 is a side view of the drinking container with a lid, FIG. 3 is a plan view of the drinking container with a lid, FIG. 4 is a perspective view of an annular elastic locking body, FIG. Is a cross-sectional view taken along the line AA of FIG. 3, FIG. 6 is a partially enlarged cross-sectional view of the main part, and FIG. 7 is a cross-sectional view during drinking.

  In the figure, a drinking container 1 with a lid is composed of a lid 2 and a drinking container 3 fitted with an annular elastic locking body 21, and the lid 2 is easily detached from the drinking container 3 due to the elastic return of the annular elastic locking body 21. Can be prevented. The lid 2 and the drinking container 3 are made of, for example, ceramic, but other materials such as plastic are not particularly problematic.

  The lid 2 closes the opening of the drinking container 3, and an annular elastic locking body 21 is attached to the outer peripheral side surface of the lid 2. A concave curved surface 22 is formed on the surface side of the lid 2, a spout 23 is formed on a part of the peripheral side of the concave curved surface 22, a collar piece 24 is formed on the outer peripheral side surface of the lid 2, and a lower side thereof. A mounting groove 25 in which the annular elastic locking body 21 is mounted is formed.

  The lid 2 has, for example, a circular outer shape when viewed from the plane, and has a certain height. The inner side is a cavity, the surface side and the side peripheral surface on which the concave curved surface 22 excluding the spout 23 is formed are closed, and the lower surface side is opened to communicate with the inner cavity. Yes.

  The ring-shaped elastic locking body 21 functions to prevent the lid 2 from being easily removed by pressure bonding to the inner peripheral side surface 31a of the opening part 31 of the drinking container 3. The annular elastic locking member 21 is a circular annular plate having a large radial width with respect to the thickness. The diameter of the outer peripheral side of the annular elastic locking body 21 is larger than the diameter of the inner peripheral side surface 31 a of the opening part 31 of the drinking container 3. The material of the annular elastic locking body 21 is made of an elastic material, and for example, silicon rubber is used.

  The annular elastic locking body 21 attached to the outer peripheral side surface of the lid 2 is pressure-bonded to the inner peripheral side surface 31a of the opening portion 31 of the drinking container 3 with the outer peripheral side having the largest diameter being reduced and inclined obliquely upward. For this reason, the annular elastic locking body 21 mounted on the outer peripheral side surface of the lid 2 always has a force to elastically return to the original wide diameter state on the outer peripheral side whose diameter is reduced, An upward force for pushing up the lid 2 is generated.

  The surface side of the lid 2 is formed as a concave curved surface 22. The concave curved surface 22 is formed, for example, from a partial shape of a concave spherical surface corresponding to the spherical surface. The concave curved surface 22 is formed to prevent the nose from hitting the surface of the lid 2 when the drinking container 3 is covered with the lid 2 and a mouth is placed on the spout 23. Further, the upper lip is easily pressed because the surface side of the lid 2 is recessed.

  A spout 23 is formed in part of the peripheral side of the concave curved surface 22 on the upper surface side of the lid 2. The spout 23 is for allowing the liquid inside to be drinkable with the lid 2 on the drinking container 3, and is sized so that at least a straw can be inserted. In use, the user can drink by inserting a straw, or by directly pressing the mouth against the spout 23 and tilting the drinking container 3 to drink the liquid inside.

  On the outer peripheral side surface of the intermediate portion in the height direction of the lid 2, a flange piece 24 is formed so as to protrude over the entire circumference. The diameter of the protruding piece 24 is larger than the inner diameter of the opening of the drinking container 3. The bottom surface of the collar piece 24 is formed in a horizontal plane. When the lid 2 is attached to the opening of the drinking container 3, the horizontal lower surface of the bowl piece 24 abuts on the upper edge of the periphery of the opening to serve as a stopper, and the lid 2 is more than necessary inside the drinking container 3. To prevent being pushed into.

  A mounting groove 25 for mounting the annular elastic locking body 21 is formed over the entire circumference on the outer peripheral side surface of the lid 2 below the flange piece 24. The groove width of the mounting groove 25 is formed slightly larger than the thickness of the annular elastic locking body 21, and the diameter of the mounting groove 25 is slightly smaller than the inner diameter of the elastic annular elastic locking body 21. Thus, the elastic annular elastic locking body 21 is attached in a slightly extended state and does not easily come off.

  The upper outer peripheral side surface 26 of the lid 2 above the flange 24 has a concave curved surface and its diameter decreases toward the upper side. When the mouth is directly attached to the spout 23, the lower lip has the concave curved surface. The shape is such that it can be easily pressed against the upper outer peripheral side surface 26.

  The drinking container 3 is formed such that the inner peripheral side surface 31 a of the opening part 31 of the container 3 to which the annular elastic locking body 21 of the lid 2 is crimped is inclined obliquely upward toward the inner side of the opening part 31. That is, the inner diameter of the upper end 31 b of the inner peripheral side surface 31 a of the opening part 31 is smaller than the inner diameter of the lower end 31 c of the inner peripheral side face 31 a of the opening part 31. Further, the inner peripheral side surface 31a of the opening portion 31 is formed to be inclined obliquely upward so as to slightly protrude toward the inner side over the entire circumference. The inclination of the inner peripheral side surface 31a includes a linear inclination and a curved inclination.

  Since the inner peripheral side surface 31a of the opening part 31 is inclined obliquely upward so as to protrude toward the inner side, the inner peripheral side surface 31a is moistened by the liquid inside, and the frictional resistance of the surface becomes small, making it easy to slip. However, it is possible to prevent the annular elastic locking body 21 from moving upward due to the inclination of the inner peripheral side surface 31a against the upward force due to the elastic restoring force acting on the annular elastic locking body 21. .

  A handle 32 is provided on the outer peripheral side surface of the drinking container 3 as necessary. When the handle 32 is provided, the user can grab the handle 32 with one hand and drink it easily. When the liquid in the drinking container 3 is hot, the hand is burned by directly holding the outer peripheral side of the drinking container 3. And the drinking container 3 is not dropped accidentally by releasing the hand that has been grasped because the drinking container 3 is too hot. When the handle 32 is provided, the lidded drinking container 1 is used as a so-called mug.

  Next, the operation of the lidded drinking container based on the configuration of the best mode for carrying out the above device will be described below.

  The lid 2 is attached to the opening of the drinking container 3 so as to prevent the liquid inside the drinking container 3 from cooling, warming, overflowing, or entering dust. When the lid 2 is attached to the opening of the drinking container 3, the annular elastic locking body 21 attached to the outer peripheral side surface of the lid 2 is annular because its outer diameter is larger than the inner diameter of the opening part 31 of the drinking container 3. The elastic locking body 21 is pressure-bonded to the inner peripheral side surface 31a of the opening portion 31 of the drinking container 3 in a state where the outer peripheral side is contracted and inclined obliquely upward.

  When the opening of the drinking container 3 is closed with the lid 2, the inside of the drinking container 3 is close to a substantially sealed state, and the inner peripheral side surface 31 a of the drinking container 3 is easily wetted by the liquid contained in the container 3. . And the friction of the contact surface of the inner peripheral side surface 31a of the opening part 31 of the drinking container 3 and the annular elastic locking body 21 of the lid 2 that is crimped to the inner peripheral side surface 31a of the drinking container 3 is obtained by wetting. The resistance becomes small and slippery.

  By the way, the annular elastic locking body 21 of the lid 2 crimped between the inner peripheral side surface 31a of the opening part 31 of the drinking container 3 is reduced in its outer peripheral side and is in an original state in a portion inclined obliquely upward. The force that tries to return elastically is always generated. The elastic restoring force that is to elastically return to the original state that is generated acts in a direction to push the annular elastic locking member 21 upward.

  On the other hand, the inner peripheral side surface 31a of the opening part 31 of the drinking container 3 to which the annular elastic locking body 21 of the lid 2 is crimped is inclined obliquely upward toward the inner side, and the inner diameter increases toward the upper side. Since it gradually decreases but gradually decreases, the inner peripheral side surface 31a formed by tilting the ring-shaped elastic locking body 21 of the lid 2 upward and tilting obliquely upward works.

  Thereby, it can prevent that the lid | cover 2 comes off easily by the elastic return of the annular elastic latching body 21, and even if the drinking container 3 inclines or falls down, the opening part of the drinking container 3 was blocked. The lid 2 is easily removed so that the liquid inside does not leak or overflow, and the surroundings are not soiled by the liquid that leaks or overflows.

  Subsequently, when the liquid inside the drinking container 3 is closed without using the straw while the opening of the drinking container 3 is closed, the mouth is directly pressed against the spout 23 and the handle 32 is grasped. By tilting 3, the liquid inside enters the mouth through the spout 23.

  At this time, since the surface side of the lid 2 is formed as the concave curved surface 22, even if the lips are pressed against the spout 23, the nose above the lips does not hit the surface of the lid 2. The disadvantage that the nose hits the surface side of the lid 2 makes it difficult to put a mouth on the spout 23 and makes it difficult to drink, and the advantage of drinking the lid by closing the opening of the drinking container 3 with the lid 2 is that the liquid inside When it is hot, it is difficult to cool, and conversely, when the internal liquid is cold, it is difficult to warm, and the internal liquid is less likely to overflow from the opening.

  Further, since the spout 23 is formed on the peripheral side of the concave curved surface 22 on the surface side of the lid 2, the upper lip hits the concave concave curved surface 22 and becomes easy to adhere. Further, since the upper outer peripheral side surface 26 of the lid 2 on which the lower lip hits is formed in a concave curved surface shape with a diameter decreasing upward and recessed, the upper peripheral side surface 26 of the concave curved surface shape with the lower lip recessed is also in close contact. It becomes easy.

  Thus, since both the upper lip and the lower lip are easy to adhere to the concave curved surface 22 and the upper outer peripheral side surface 26 on the surface side of the lid 2, it becomes easy to drink. In addition, there is no gap between the lip pressed against the spout 23 and even if the drinking container 3 is tilted greatly, part of the liquid does not leak out while drinking.

  The present invention is not limited to the best mode for carrying out the above-described invention, and various modifications can be made without departing from the spirit of the present invention.
