  By the way, as for the thing of patent documents 1-3, when all remove | eliminate a cover body from the mouth member or plug member attached to the heat insulation container, the tanning container attached to these mouth members or the plug member is the mouth. Since it is opened upward via the member or the plug member, as disclosed in Patent Document 1, hot water is poured from above into the extract material such as herb tea or green tea contained in the brewing container, Extraction is possible. However, the most decoction can be performed.

  On the other hand, in recent times, while these heat retaining bottles with a scouring container are carried and used repeatedly as my bottles, especially for herbal teas that take time to extract, the extractant is immersed in the content liquid. It is convenient to carry and use as it is, and herb tea does not cause excessive bitterness like green tea even if it is immersed all the time, so it can be used until it is disassembled and washed. It has increased.

  In addition, there is also a demand for a large capacity that can be used for work, school, and other activities after leaving the house and continuing to use it until returning home.

  However, all of the tanning containers described in Patent Documents 1 to 3 have a shape that is shallower than their opening diameter with respect to the depth of the heat insulating container. Cannot be immersed in the content liquid and cannot meet the recent demand for long-time immersion. Further, in order to increase the capacity without impairing the portability, the ratio of the depth to the body diameter is increased, but in this case, the ratio of the immersion time to the total capacity becomes increasingly shorter.

  Further, like the one disclosed in Patent Document 1, a mouth member or a plug such as those disclosed in Patent Documents 1 to 3 is used as a drinking mouth as an upper end opening of a metal vacuum double container as a heat insulating container. If the member is screwed to the inner periphery of the upper end opening, the threaded portion may disturb the flow to the drinking mouth, making it difficult to swallow, and the content liquid may be leaked sideways to transfer it to others. Japanese Patent Application Laid-Open No. H10-228688 responds to this by eliminating the screw in a specific range in the circumferential direction, but in that case, the drinking position and the outflow position are adjusted to that even though the entire drinking mouth is open. It is necessary and difficult to use.

  An object of the present invention is to provide a heat retaining bottle with a strainer that is suitable for the recent demand for long-time immersion and increase in capacity, and can be easily taken as needed.

A stopper that closes the mouth, and a tanning container that is attached to the lower part of the mouth member of the stopper so that the upper end opening can be attached and detached, enters the heat insulating container, and is immersed in the content liquid, One feature of the tanning container is that it satisfies the relationship of upper end opening diameter <depth, and reaches the middle depth region of the heat insulating container.

In such a configuration, the heat insulating container, the plug body, and the tanning container can be disassembled and washed in one by a detachable mounting portion, and the contents liquid can be closed when the plug body is mounted on the heat insulating container. It is possible to store liquids or carry them while keeping them cold or warm due to the heat insulating properties of the heat insulating container while preventing leakage. At the same time, the lower part of the mouth member of the plug body having a mouth member attached to the heat insulating container with the first screw fitting portion and a lid attached to the upper end opening of the mouth member with the second screw fitting portion. in a strained extraction member that accommodates therein when mounting the container,漉 to satisfy the relationship of the upper end opening diameter <depth of the container, a long time immersed in liquid contents by the new form reaches the middle depth range of the heat insulating container It is easy to make it so that it can be used at any time by removing the extraction material by opening it by removing the container, etc. In addition, since the stopper is attached to the outer periphery of the upper end opening of the heat insulating container, there is no effect on the inner periphery, and the screw is obstructive or the screw is used in the circumferential direction even when the upper end opening of the heat insulating container is used as a drinking mouth. The drinking position or the like is not limited to a specific position in the circumferential direction without the part. In addition, the lid is simultaneously opened at the upper end of the mouth member on the condition that the lead angle of the screw fitting portion with the mouth member is larger than that of the first screw fitting portion between the mouth member and the heat insulating container mouth portion. The tanning container can be opened and closed.

  Hereinafter, embodiments of the heat retaining bottle with a strainer of the present invention will be described with reference to the drawings. However, the following description is a specific example of the present invention and does not limit the description of the scope of claims.

  A heat retaining bottle 1 with a strainer of the present embodiment shown in FIG. 1 is mounted so as to be detachable from the inner periphery or outer periphery of the heat insulating container 2 and the upper end drinking mouth 3 part of the heat insulating container 2, and the upper end of the heat insulating container 2 is attached. A stopper 4 that closes the drinking mouth 3, and a squeeze container 6 that is attached to the lower part of the stopper 4 so that the upper end opening 5 can be attached and detached, enters the heat insulating container 2, and is immersed in the content liquid. In particular, the tanning container 6 satisfies the relationship of upper end opening diameter <depth. The heat insulating container 2 has an outer surface exposed as a stainless steel metal vacuum double container in which the inner and outer cylinders 2a and 2b are made into a vacuum heat insulating space 2c, and has a joining edge formed by welding between the upper ends of the inner and outer cylinders 2a and 2b. It has a thin and circular drinking mouth 3, and has a smooth finished surface that is deburred and buffed. Moreover, the plug body 4 is made of a synthetic resin, so that moldability is ensured in addition to weight reduction and cost reduction. Further, the tanning container 6 is formed by pressing a metal plate which is corrosion-resistant and harmless on food such as stainless steel, aluminum, copper and tin, and is provided with a punching hole. However, the vacuum double container can be structured to be accommodated in the outer case, or other heat insulating structure can be adopted or combined. The tanning container 6 can be replaced by a press-molded net made of the metal material or connected to the upper end opening 5 made of a metal plate or metal rod.

  In the heat retaining bottle 1 with a strainer as described above, the heat insulating container 2, the plug body 4, and the scooping container 6 can be disassembled and washed in their entirety as shown in FIG. . Further, when the plug 4 is attached to the heat insulating container 2 as shown in FIG. 1, it can be closed, so that the liquid can be stored or carried by keeping the heat insulated or insulated by the heat insulating property of the heat insulating container 2 while preventing leakage of the content liquid. it can. At the same time, when the strainer 6 is attached to the stopper 4 attached to the heat insulating container 2, the extractant contained therein satisfies the relationship of the upper end opening diameter <depth of the tea strainer 6 as shown in FIG. It is easy to immerse in the content liquid 9 for a long time depending on the new form, and it can be dealt with at any time by removing the extraction material by opening the container 6 by removing the squeeze container 6 or the like.

  As a result, the heat insulating container 2, the plug body 4 and the tanning container 6 are each disassembled and washed in a round and easy to keep the details clean. In addition, the stopper 4 is attached to the heat-insulating container 2 so that the liquid can be stored or carried while being kept cold or warm while preventing liquid leakage. When the lid 4 is attached to the heat insulating container 2, the scum container 6 supported by the lid 4 is immersed in the content liquid 9, and the extraction material placed in the scum container 6 is squeezed until the container 6 is removed. In particular, it is suitable for the extraction of herbal tea because it is easy to immerse in the content liquid 9 for a long time by the new form satisfying the relationship of the upper end opening diameter <depth of the tea strainer 6 and is suitable for the extraction of herbal tea and not suitable for long-time soaking. The extraction object can be dealt with at any time by opening it by removing the container 6 and discharging the extraction material, and this does not cause a problem.

  In addition, as in the present embodiment, the plug body 4 is mounted so as to be detachable from the outer periphery of the upper end opening 3 portion of the heat insulating container 2, so that the inner periphery of the upper end opening 3 has an influence on the detachable structure. There is nothing, but the upper end opening of the heat insulating container 2 is used as the drinking mouth 3, so that the screw gets in the way, or the drinking position is restricted to a specific position in the circumferential direction by eliminating a part of the circumferential direction of the screw. There is nothing. That is, it is not necessary to consider the conventional method of partially removing the inner peripheral screw, and the drinking position is not limited to a specific position in the circumferential direction.

  Further, the plug body 4 is mounted so as to cover the upper end drinking mouth 3 from above so that it can be attached to and detached from the upper end drinking mouth 3 of the heat insulating container 2 by the mounting section 7, and the mounting section 8 is attached to its lower end portion. An annular mouth member 41 that opens the inside of the tanning container 6 so that it can be attached and detached, and an mouth member 41 that is attached to the upper end opening 11 of the mouth member 41 so that it can be attached and detached at the attachment portion 12. And a lid 42 for closing the upper end opening 11. Here, the mounting portions 7 and 12 are screw fitting portions, and the mounting portions 8 are detachable mounting portions 7, 8, and 12 as helicoid engaging portions. Thus, since the mouth member 41 covers the upper end drinking mouth of the heat insulating container 2, as shown in FIG. 3 and 4 can be opened as shown in FIGS. 3 and 4, since the lid member 42 is removed so that the tanning container 6 supported at the lower end can be opened. The extraction material accommodated in the can be discharged. In this case, by removing the mouth member 41 from the heat insulating container 2, the container 6 can be discharged together with the mouth member 41 upside down. Therefore, the mouth member 41 covers the upper end drinking mouth 3 of the heat insulating container 2 and is supported at the lower end by removing the lid body 4 while protecting from dirt and external force during carrying, handling, etc. other than during round washing and direct drinking. The tanning container 6 can be opened and the extraction material can be easily taken out and discharged. If the mouth member 41 is removed from the heat insulating container 2, it can be inverted and discharged more easily and washed off.

Further, as shown in FIGS. 1 and 3, the lid body 42 is fitted on the back side with the bottom portion 6 a of the tanning container 6 as shown in FIGS. 3 and 4, and the mouth member on which the rinsing container 6 is mounted. It is assumed that it has a dent that is held together with 41 in a standing posture. As a result, the lid 42 is removed from the mouth member 41 and placed upside down, the back side recess 42a is directed upward, the mouth member 41 is removed from the heat insulating container 2 with the container 6, and the bottom 6a of the container 6 is removed. Is fitted in the recess 42a of the lid 42 facing upward and held in an upright state, and the heat insulating container 2 alone can be directly drunk. Therefore, the mouth member 41 with the tanning container 6 is removed from the heat insulating container 2, and the bottom portion 6a of the tanning container 6 is fitted into the recess 42a that faces upward from the lid 42 that is removed from the mouth member 41 and placed upside down. The mouth member 41 with the tanning container 6 can be held in an upright state, and the exudation liquid from the tanning container 6 can be stored in the recess 42a. Without wetting, the heat insulating container 2 alone can be directly consumed, which is convenient. Here, the recess 42a, by having a size which can accommodate the amount of liquid seeps from straining container 6, exudation liquid leaks outside the cover 42, such as wetting around the lid 42 This can be prevented.

  Further, as shown in FIGS. 1, 2, and 3, the tanning container 6 is configured such that the bottom portion 6 a side of the body portion 6 b that fits into the recess 42 a is smaller than the body portion diameter. As a result, even if the bottle 6 is advantageous in terms of capacity to be mounted on the lower end portion of the mouth member 41 as much as possible, it fits in the recess 42a of the lid 42 on the bottom 6a side smaller than the body diameter. Therefore, even if the lid member 42 is large enough to cover and cover the inner periphery of the mouth member 41 attached to the heat insulating container 2 like the mounting portion 12 in the illustrated example. It can be fitted and held in a recess 42a provided in a narrow range inside the screw fitting space to the inner periphery of the material. Therefore, when the tanning container 6 is to be attached to the lower end portion of the mouth member 41 with a diameter as large as possible, the mouth member is fitted into the recess 42a of the lid 42 on the bottom portion 6a side smaller than the body diameter. The cover body 42 having the minimum necessary size can be fitted into and held in a narrow area inside the screw fitting space, and can be held. It is possible to avoid inconvenience for carrying a bulk by making the diameter larger than necessary.

  More specifically, in order to eliminate the liquid leakage by attaching the stopper 4 to the upper end drinking mouth 3 of the heat insulating container 2, as shown in FIG. On the other hand, the gap between the inner wall 41a supporting the container 6 and the throttle step portion 21 provided at the back of the upper end drinking mouth 3 is sealed by a seal member 22 sandwiched with vertical and horizontal pressure contact allowances. In addition, between the lower end portion of the inner wall 42a of the lid 42 attached to the inner periphery of the opening 11 portion of the mouth member 41 by the attachment portion 12 and the step portion 23 at the back of the attachment portion 12 of the inner wall 41a of the mouth member 41. Are sealed by a sealing member 24 sandwiched between them with a pressure contact margin in the horizontal and vertical directions. The seal member 22 is elastically fitted and held in the groove 41b on the outer periphery of the lower end portion of the inner wall 41a, and the seal member 24 is elastically fitted and held in the groove 42c on the outer periphery of the lower end portion of the inner wall 42b of the lid body 42. doing. However, it is not limited to this.

  The mouth member 41 is a combination of the outer wall 41e that supports the seal member 22 and is ultrasonically welded by applying a downward stepped portion 41d from above onto an outward flange 41c at the upper end of the inner wall 41a having the stepped portion 23. In addition to forming the upper end opening 11 and the mounting parts 7 and 12 in the outer wall 41d, the inner wall 41a is between the inner periphery of the upper end drinking mouth 3 part of the heat insulating container 2 and the vacuum heat insulating space 2c of that part. A heat insulating space 25 having a width equal to or larger than the width of the heat insulating space 25 is formed. Further, the lid 4 has a combination structure with the outer wall 42e attached with the sealing member 24 and ultrasonically welded to the outward flange 42d at the upper end of the inner wall 42b where the mounting portion 12 and the recess 42a are formed. A heat insulating material 26 is accommodated in a hollow portion formed between the inner and outer walls 42b and 42e to suppress heat escape to the upper portion together with the heat insulating space 25. On the outer periphery of the outer wall 42e, a cover wall 42f that covers and covers the shoulder 41e between the upper end opening 11 forming portion of the mouth member 41 and the mounting portion 7 forming portion is integrally formed. The cover wall 42f is formed to have a continuous surface with substantially the same diameter as the mounting portion 7 forming portion of the outer wall 41d of the mouth member 41.

  In the case where the stopper member 4 is left attached to the heat insulating container 2 and only the lid member 42 is to be removed, the stopper member 4 is in a state where the attaching portion 7 forming portion exposing the mouth member 41 is held with one hand. If the lid 42 is gripped with the other hand and rotated independently in the screw unwinding direction, it can be easily achieved regardless of whether the pressure contact resistance by the seal members 22 and 23 is equal or there is a magnitude relationship, When the mouth member 41 and the lid 42 are integrated, that is, when it is desired to remove the entire plug body 4 from the heat insulating container 2, the mouth member 41 is exposed with the other hand while the heat insulating container 2 is held with one hand. This can be easily achieved by gripping the mounting portion 7 forming portion and rotating it alone in the screw-back direction.

Finally, as shown in FIGS. 1 and 5, the mounting portion 8 serving as a helicoid engaging portion includes protrusions 8a1 and 8a2 provided at two positions in the circumferential direction of the upper end opening 5 of the scooping container 6, and the protrusions 8a1 and 8a2. Is received from the two upper and lower attaching / detaching ports 8b1 and 8b2 shown in FIG. 5 from above in the axial direction, and is then constituted by helicoids 8c1 and 8c2 which are engaged with them by the subsequent rotation of the tanning container 6 and are prevented from coming off. Yes. In particular, the helicoids 8c1 and 8c2 are provided with outward flanges 5a around the upper end opening 5 of the scooping container 6 from the attachment / detachment ports 8b1 and 8b2 toward the engagement regulating end 8c3 shown in FIG. The outer flange 5a is pressed against the upper surface of the helicoids 8c1 and 8c2 with a predetermined force at a position where the protrusions 8a1 and 8a2 reach the engagement restricting end 8c3. Then, the support state to the mouth member 41 is stabilized by the pressure friction. Therefore, in order to remove the crimping container 6 from the mouth member 41, it is necessary to overcome the pressure contact force and rotate the twisting container 6 with respect to the mouth member 41 in the opposite anti-engagement direction.
