Description

  The present invention relates to a heat-resistant beverage dispensing container having a screw-type lid.

  Beverage pour-out containers such as cold water bottles that can store beverages such as tea and water and pour the drinks into hot drinks are often equipped with screw-type lids that can be removed and injected easily. Has been. Such a beverage dispensing container generally has a structure that opens and closes the sealing port of the beverage storage section on the main body side by rotating the lid. When storing beverages with a relatively low temperature, such as normal temperature beverages or cold water, the screw-type lid is separated from the main body, poured into the beverage, and then stored in the refrigerator, so the lid can be sealed immediately. .

  FIG. 7 is a view showing the entire conventional beverage dispensing container. The beverage dispensing container 100 shown in FIG. 7 is configured such that a lid 130 can be separated into an inner lid 160 and an upper lid 140. A handle 160 a and a spout 160 b are formed in the inner lid 160 and attached to the liquid storage unit 120. The upper lid 140 has a screw-type stopper 140a, and the stopper 140a is attached to the sealing port 160c of the inner lid 160 by screwing.

  On the other hand, recently, the use of packed tea leaves has increased, and many heat-resistant materials have been used. However, even if the structure or material is resistant to heat, if the lid 130 is sealed immediately after pouring hot water, a large load is applied to the container due to a change in internal pressure accompanying a temperature change.

  Specifically, when the temperature of the hot water decreases after the lid 130 is sealed and the internal pressure decreases, stress is generated in the container body, particularly the liquid storage unit 120, and it is impossible to fix the lid 130 to the sealing port 160c. If it is attempted to open it, there is a risk that deformation will occur in the fixed part or the handle 160a. In particular, when stored in a refrigerator or the like, the internal pressure change further increases. As described above, when the screw-type lid with high hermeticity is closed in a state where the temperature is not sufficiently lowered, the fatigue life of the container is shortened, and in some cases, there is a risk of causing fatigue failure such as a crack.

  Therefore, in order to improve the fatigue resistance of containers, the strength of materials and structures has been conventionally improved, and it is necessary to call the user's attention with a note to seal the lid after the temperature drops. there were.

  The configuration of the screw-type sealed chilled water cylinder as described above is described in Patent Document 1, for example.

JP 2004-224354 A

  However, if ribs are frequently used to improve the strength, the aesthetic appearance is impaired, and molding during production and maintenance during use becomes difficult. Further, when strengthening by increasing the wall thickness, the weight increases, so that the usability deteriorates. Further, when a transparent member is used, it is difficult to realize the intended transparency.

  The effects of instruction manuals and labels provided for alerting depend on the user's interpretation and attention, and it is difficult to obtain a certain effect for all users. is there. In other words, it is predicted that the product may be used without noticing the notice, or used in an unintended state by the manufacturer due to excessive trust in the product, and it is difficult to obtain a sufficient effect.

  Then, in order to solve the said problem, in this invention, it aims at providing the drink extraction container which is hard to produce misuse irrespective of the temperature of the drink to accommodate.

  In order to achieve the above object, the beverage dispensing container of the present invention is a beverage dispensing container in which the sealing port between the spout and the beverage container can be sealed with a screw-type upper lid. And a shelf-like projection formed so as to protrude in the diameter-reducing direction, and an annular body that is formed to have substantially the same diameter as the shelf-like projection and is interposed between the upper lid and the shelf-like projection, A spacer capable of maintaining a predetermined distance between the shelf-like protrusion and the annular body is provided on one of the shelf-like protrusion and the annular body, and a fitting portion in which this spacer can be buried is formed on the other, Of the first mounting state of the annular body in which the spacer is buried in the fitting portion and the second mounting state in which the spacer holds the height of the annular body with respect to the shelf-like protruding portion at a predetermined distance, The position of the receiving part on the annular body side that receives the contact part in the first placement state is higher than the position of the contact part when fully closed. The position of the receiving portion in the second placement state is located above the position of the abutting portion when fully closed, and the edge of the fitting portion protrudes toward the spacer placement side. A protruding edge portion is formed.

  With this configuration, in the first placement state, the receiving portion on the annular body side with respect to the upper lid is positioned below the height of the contact portion on the upper lid side when fully closed due to the spacer being buried in the fitting portion. Since it moves backward, the upper lid can be fully closed. Further, in the second mounting state, the interval between the shelf-like protruding portion and the annular body is held at a predetermined distance by the spacer, and the receiving portion on the annular body side that contacts the upper lid is the abutting portion on the upper lid side when fully closed Therefore, the upper lid is restricted from rotating in the closing direction. Further, since the protruding edge portion is formed so as to protrude toward the spacer arrangement side at the periphery of the fitting portion, it slides toward the fitting portion along the circumferential direction with respect to the shelf-like protruding portion or the annular body. The tip of the spacer that has been moved is prevented from sliding at the protruding edge.

  Thereby, when putting a drink with a comparatively low temperature which can make an upper lid into a fully-closed state immediately, if an annular body is set to the 1st loading state, it can be fully closed.

  In addition, when it is not preferable to immediately close the upper lid as in the case of immediately after the hot water is charged, the annular body is set to the second placement state, and the closing direction is set before the upper lid is fully closed. Therefore, it is possible to prevent full closure.

  Further, in the second mounting state, the contact portion of the rotating upper lid and the receiving portion of the annular body are in sliding contact, and the spacer is fitted even if the annular body is driven (rotated) by the rotation of the upper lid. Since the sliding is restrained at the protruding edge before reaching the joint part, the spacer can be prevented from being buried in the fitting part, and the distance between the annular body and the shelf-like protruding part is kept at a predetermined distance. can do. That is, it is possible to prevent the rotation from the second placement state to the first placement state due to the rotation of the upper lid.

  Moreover, in addition to the structure described in claim 1, the beverage dispensing container of the present invention is characterized in that the annular body is integrally formed with a tea strainer portion that extends inward of the beverage storage portion.

As described above, according to the present invention, the annular body interposed between the stopper lid (upper lid) and the sealing opening, and the shelf-like protrusion formed on the inner peripheral edge of the sealing opening, the spacer and Since the configuration comprising the combination with the fitting portion is provided, the first mounting state in which the annular body can be fully closed and the rotation in the closing direction are regulated immediately before the annular body is fully closed. The second placement state can be selected. This makes it possible to use two different mounting states for a relatively low temperature beverage that can be fully closed immediately and for hot water that cannot be fully closed immediately. it can. Therefore, even when a high temperature beverage is drastically changed due to a decrease in temperature, the stopper lid is sealed in a high temperature state and stress can be prevented from being generated in the container, so that it is possible to improve fatigue durability. .

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
First, a beverage dispensing container according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 shows the beverage dispensing container in a disassembled state.

  As shown in FIG. 1, a beverage dispensing container 1 according to the present embodiment is composed of a container main body 2, an inner lid 6, an upper lid 4, and a tea strainer 8 serving as a beverage container.

  A spout 6 a is formed in the inner lid 6 and is attached to the container body 2 by screwing.

  The tea strainer 8 has a flange 8a formed in the upper region formed in a cylindrical shape along the circumferential direction. In the lower part, a tea strainer is formed in which a mesh member 8d is stretched in an opening 8c formed by cutting a cylinder obliquely. Also, below the flange 8a, spacers 8b are formed at three locations at intervals that divide the circumferential direction into three equal parts. The tea strainer 8 is placed in a closed opening inside the inner lid 6. With such a configuration, tea leaves or packed tea leaves can be arranged in the tea strainer 8, and hot water can be poured from above and immersed in the container body 2 to exude the tea components.

  The upper lid 4 is a screw-type stopper lid, and is attached to the inner lid 6 by screwing so as to sandwich the tea strainer 8 dropped inside the inner lid 6.

  In this way, the tea strainer 8 interposed between the upper lid 4 and the inner lid 6 can be separated, and the used tea leaves can be removed together with the tea strainer 8, so that after the upper lid 4 is fastened to the inner lid 6, , It can be stored horizontally or vertically.

  Next, the structure of the inner lid 6 will be described with reference to FIG. FIG. 2 is an enlarged view showing the inside of the inner lid 6 of the beverage dispensing container 1 of FIG.

  On the inner side of the inner lid 6, a screw thread 6 f that is screwed with the upper lid 4 is formed in the vicinity of the upper opening end, and the inner diameter of the sealing port 6 b that seals the space for containing the beverage is reduced in the diameter reducing direction. A shelf-like protruding portion 6c protruding in the circumferential direction is formed. A notch 6d (fitting portion) is formed in the shelf-like protruding portion 6c at a position that divides the circumferential direction into three equal parts.

  Further, a protruding edge 6e protruding upward is formed at the periphery of the notch 6d.

  Here, both the notch 6d and the spacer 8b are formed at positions that divide the circumferential direction into three equal parts, so that the positions of the tea strainers 8 can be overlapped with each other in a plan view. . Since the width of the notch 6d is formed to be wider than the width of the spacer 8b, the spacer 8b can be fitted between the notches 6d. As described above, the tea strainer 8 abuts the placement state (first placement state) in which the spacer 8b is inserted into the notch 6d and the lower end of the spacer 8b at any position on the upper surface of the shelf-like protruding portion 6c. It is possible to select and place two placement states, that is, a placement state (second placement state) to be performed.

  Subsequently, these two placement states will be described with reference to FIGS. 3 and 4. FIG. 3 is a cross-sectional view showing a state (first placement state) in which the tea strainer 8 is placed so that the spacer 8b is fitted into the notch 6d of the inner lid 6. FIG. 3A is an enlarged view of the range including the upper lid 4 from the upper end of the container body 2, and FIG. 3B shows the lower end 4 b of the upper lid 4 and the periphery of the flange 8 a of the tea strainer 8. Is further enlarged.

  FIG. 4 is a cross-sectional view showing a state (second placement state) in which the tea strainer 8 is placed such that the lower end of the spacer 8b comes into contact with the upper surface of the shelf-like protrusion 6c of the inner lid 6. is there. Here, as in FIG. 3, FIG. 4A shows an enlarged range including the upper lid 4 from the upper end of the container body 2, and FIG. 4B shows the lower end 4 b of the upper lid 4 and the tea strainer 8. The periphery of the flange 8a is further enlarged.

  As described above, when the arrangement angle of the tea strainer 8 is set so that the arrangement of the notch 6d and the spacer 8b overlaps in plan view, each spacer 8b can be buried between the notches 6d. 3 (a) and 3 (b), in this state, the packing 7 of the upper lid 4 that has come down by the rotation in the closing direction and the inner peripheral surface of the sealing port 6b of the inner lid 6 can come into contact with each other. The moment of becoming fully closed.

  Then, the position of the lower end 4b of the upper lid 4 at the moment when the packing 7 is in contact with the sealing port 6b is the position of the contact portion (lower end 4b) of the upper lid 4 when fully closed, and in FIG. This is shown as a closed position 4a. In addition, the "contact part" said here means that the lower end 4b of the upper cover 4 contacts the flange 8a (receiving part) of the raised tea strainer 8 in the second placement state described below. It is a contact part in.

  Thus, when the spacer 8b is disposed so as to be buried in the notch 6d, the position of the upper surface of the flange 8a as the receiving portion for receiving the lower end 4b is equal to or lower than the height position of the lower end 4b when fully closed, that is, the fully closed state. Since it descends to a height below the position 4a, the upper lid 4 can be fully closed.

In addition, as shown in FIGS. 4A and 4B, in the arrangement where the spacer 8b is not buried in the notch 6d, that is, in the state where the lower end of the spacer 8b is in contact with the upper surface of the shelf-like protruding portion 6c, the spacer 8b The flange 8a of the tea strainer 8 is lifted by the height of (a predetermined distance). Thereby, the upper surface (receiving part on the annular body side) of the flange 8a that comes into contact with the lower end 4b (contact part) of the upper lid 4 is arranged at a position higher than the fully closed position 4a shown in FIG. The sealing port 6b cannot be closed.

  Therefore, as shown using FIG. 3 and FIG. 4, in the beverage dispensing container 1 in the present embodiment, by selecting the arrangement angle of the tea strainer 8, the upper lid 4 can be placed in a fully closed state (first ) And an arrangement in which the upper lid 4 cannot be fully closed (second placement state) can be used in accordance with the state of the beverage to be charged.

  For example, when the upper lid 4 is immediately closed and stored, the tea strainer 8 may be disposed in a state where the spacer 8b is fitted into the notch 6d as shown in FIG. With this arrangement, there is no restriction on the closing direction of the upper lid 4, and the fully closed state can be achieved. For this reason, the top lid 4 can be closed and stored in a refrigerator or the like in a state in which packed tea leaves that can be drained are put into the tea strainer 8.

  However, when the upper lid 4 is immediately sealed, such as when brewing hot water and brewing tea in the beverage dispensing container 1, there is a possibility that stress may be generated in the container due to a change in internal pressure accompanying a temperature drop. As shown in FIG. 4, the arrangement angle of the tea strainer 8 may be set so that the lower end of the spacer 8b comes into contact with the shelf-like protrusion 6c. With this arrangement, before the upper lid 4 is fully closed, the lower end 4b abuts against the upper surface of the flange 8a raised by the height of the spacer 8b, and the rotation in the closing direction is restricted. Thus, it is possible to prevent the upper lid 4 from being closed in a high temperature state.

  As described above, the structure for restricting the rotation of the upper lid 4 in the closing direction is provided in the tea strainer 8 as the flange 8a and the spacer 8b. Therefore, when tea is brewed, the tea strainer must be used for restricting the rotation. The configuration will be arranged. Moreover, in the structure shown in this Embodiment, since the area | region occupied in the circumferential direction of the shelf-shaped protrusion part 6c is formed so that it may become larger than the area | region which the notch 6d occupies, the state shown in FIG. The probability of being placed in is high. Thus, the structure is easy to function in a safe direction without special consideration.

  Further, as shown in FIG. 2, a protruding edge 6e is formed to protrude upward at the periphery of the notch 6d. This is provided in order to more reliably function the above-described rotation restriction in the closing direction of the upper lid 4. That is, even when the tea strainer 8 is arranged so as to be in the state of FIG. 4, until the upper lid 4 rotates to some beat, or until the upper lid 4 reaches the above closed rotation restriction position. In addition, along with this rotation, the tea strainer 8 that is in sliding contact with the upper lid 4 may be driven. And the case where the spacer 8b rotated along the circumferential direction approaches the notch 6d can be considered. However, even in such a case, the rotation of the spacer 8b that has rotated in the circumferential direction is suppressed by the protruding edge 6e at the periphery of the notch 6d. Thereby, it is possible to prevent the spacer 8b from being inserted between the notches 6d in an unintended state.

(Second Embodiment)
Next, a beverage dispensing container according to the second embodiment of the present invention will be described with reference to FIGS.

  The beverage dispensing container 10 in the present embodiment shown in FIG. 5 is the same as the beverage dispensing container 1 shown in FIG. 1 in the first embodiment with respect to the container main body 2 and the upper lid 4 serving as a beverage container. However, the inner lid 16 and the tea strainer 18 are different in structure.

As apparent from FIG. 5, in the present embodiment, a notch 18 b is formed in the flange 18 a of the tea strainer 18. A projecting edge 18c is formed on the periphery of the notch 18b.

  Further, as apparent from FIG. 6, the shelf-like protrusion 16c formed in the vicinity of the sealing port 16b of the inner lid 16 along the circumferential direction has a notch 6d as in the inner lid 6 of FIG. Is not formed, and a spacer 16d is provided upward instead.

  As described above, in the present embodiment, the spacer 16d and the notch 18b are provided on the opposite sides with respect to the configuration of the flange and the shelf-like protrusion shown in the first embodiment. With such a configuration, when the tea strainer 18 is arranged so that the spacer 16d of the shelf-like protruding portion 16c is buried in the notch 18b of the flange 18a, the upper end of the tea strainer 18 is downward as in the state of FIG. By retracting, the upper lid 4 can be fully closed.

  In addition, when the tea strainer 18 is arranged in a state where the tip of the spacer 16d of the shelf-like protruding portion 16c is in contact with the lower surface of the flange 18a, the upper lid 4 is fully closed as in the state shown in FIG. Can be regulated.

  Further, since the protruding edge portion 18c is formed at the peripheral edge of the notch 18b of the flange 18a, the tea strainer 18 is driven as the upper lid 4 rotates, and the notch 18b rotates along the circumferential direction. However, when approaching the position of the tip of the spacer 16d, the rotation of the tea strainer 18 is suppressed, and the closed rotation restricted state of the upper lid 4 can be maintained.

  In each of the above embodiments, in order to restrict the rotation of the upper lid in the closing direction, the first embodiment includes a configuration including a tea strainer having a flange and a spacer as an example. In the embodiment, a configuration including a tea strainer having a flange and a notch is shown as an example. However, in order to restrict the rotation of the upper lid in the closing direction with respect to hot beverage input and to allow the cold beverage to be fully closed, the tea strainer function may not be provided. That is, the opening and mesh of the lower half of the tea strainer do not necessarily need to be included, and it is sufficient to have a cylindrical body (annular body) in which a flange having an upper half spacer or notch is formed.

  Further, in each of the above embodiments, the configuration in which the spacers and the notches are respectively formed at three locations has been shown as an example, but may be provided at a single location or a plurality of locations other than 3 locations. There is no need to have the same number of configurations.

  Further, in each of the above embodiments, the notch is given as an example of the configuration in which the spacer can be buried. However, if the configuration can change the contact position with the upper lid by inserting the spacer, the bottom has a bottom. A concave fitting part may be sufficient.
