Description

  The present invention relates to a beverage container with a cover provided with a container cover that fits in a state in which a container body exposes an upper end opening / closing part.

This type of beverage container with a cover prevents the temperature change of the beverage by adopting a container body having a heat insulating part between the inner cylinder and the outer cylinder, and the container cover is provided for the purpose of improving the portability and protection of the container body. It is provided.
The container body having the heat insulating portion is provided with a container opening / closing structure at the upper end. Since it is troublesome to open the container cover every time a drink is taken, a container cover that is opened so that the upper end opening / closing portion of the container body is exposed is used. When this type of container cover is employed, the container body is usually carried or tilted while holding the container cover. At this time, it is necessary to prevent the container body from coming out of the container cover. In particular, even when the container body is tilted in the full state, it should not be pulled out upward (referred to above and below the container body; the same applies hereinafter). Is essential. When this happens, the drinking mouth hits the mouth or the container mouth hits the cup.

Conventionally, as a container cover in consideration of upward slipping, it has a bottom cover part on which the container body is placed and a peripheral cover part that wraps the container body from the outer diameter side, with the notch of this peripheral cover part as a boundary The thing which fastened the circumferential direction both sides with the locking tool is utilized.
If this container cover is adopted, when the container body is put into the container cover, the locking member is released or loosened, and the peripheral cover part is opened from the cut part or the opening of the container cover is widened. Can easily put the container body. The dropout of the container body to the lower side is received by the bottom cover part and can be reliably eliminated. By fastening the peripheral side cover portion with a locking tool, the peripheral side of the container body can be tightened to prevent the container body from coming off to the upper side. Even if the peripheral side of the container body is tightened with the peripheral side cover part, the peripheral side of the container body has the rigidity necessary to secure the heat insulating space because it has a heat insulating part between the inner cylinder and the outer cylinder. The tightening does not cause the peripheral side of the container body to escape, and the inner diameter contraction portion can be pressed firmly.

  In order to more reliably prevent the container body from being pulled out upward, the inner diameter of the anti-slip material is positioned higher than the lower end of the cut portion of the peripheral cover portion on the peripheral side or peripheral cover portion of the container body. A beverage container with a cover is provided, wherein a reduced portion is attached, and the inner diameter reduced portion is pressed against the container body by tightening the peripheral cover portion by fastening the locking device, thereby increasing the frictional force between them. It has been proposed (Patent Document 1).

JP 2006-176170 A

However, in the beverage container with a cover as described in the above-mentioned Patent Document 1, the tightening of the peripheral cover portion may be loosened or lost unexpectedly for some reason. For example, when a thing which can adjust the fastening position in the circumferential direction by the locking tool, such as a hook-and-loop fastener or a string, is used, it is possible that the tightening of the circumferential cover portion becomes loose.
Since the inner diameter reduction part of the above-mentioned Patent Document 1 is at the upper part of the peripheral cover part, close to the opening and far from the bottom cover part, it is on the easily deformable side of the peripheral cover part, and the above-mentioned tightening looseness occurs. The inner diameter reduced portion tends to float from the container body. Since the container body of Patent Document 1 described above has a gently downwardly extending peripheral side, for example, even if the inner diameter reduced part floats somewhat from the container body and the container body moves upward, the inner diameter reduced part eventually becomes smaller. Although it can be caught by the lower outer diameter of the container body, until then, the container body may come out upward and hit the mouth or the like.

  In view of the above circumstances, an object of the present invention is to make it difficult for the inner diameter reduced portion of the container cover to float from the container body, and to reduce the amount of the container body that protrudes upward when the container is lifted.

This invention which solves the above-mentioned subject is provided with a container body which has a heat insulation part between an inner cylinder and an outer cylinder, and a container cover which this container body fits in the state where the upper end opening-and-closing part was exposed, and this container cover is said container A bottom cover portion on which the body is placed, and a circumferential cover portion that wraps the container body from the outer diameter side, and the circumferential both sides of the circumferential cover portion are fastened together with a locking tool And a cover-equipped beverage container provided with an inner diameter reduced portion that is pressed against the container body by fastening the locking member on the peripheral cover portion.
As described above, release or loosen the locking tool to easily put the container body, securely remove the bottom of the container body with the bottom cover part, tighten the peripheral side of the container body with the peripheral cover part, This is to prevent the container body from being pulled upward by pressing the reduced portion.

According to the present invention, based on the premise, an outer diameter enlargement portion having a maximum outer diameter larger than the inner diameter reduction portion of the container cover is provided on the lower peripheral side of the container body, and the inner diameter reduction portion is provided below the peripheral cover portion. And the inner diameter reduced portion is located on the upper side of the maximum outer diameter of the outer diameter enlarged portion in a state where the locking tool is fastened.
According to this configuration, the inner diameter reduced portion of the peripheral cover portion is located below the peripheral cover portion, which is the hard to deform side, close to the bottom cover portion of the container cover. The part is difficult to float from the container.
In a state where the container body is placed on the bottom cover portion of the container cover, the vertical positional relationship of the container body with respect to the container cover is determined. When the locking tool is fastened, the inner diameter reduced part at the lower part of the peripheral cover part and the maximum outer diameter of the outer diameter enlarged part at the lower peripheral part of the container body are on the same side in the vertical direction. The reduced portion is pressed close to the upper side of the maximum outer diameter of the outer diameter enlarged portion. For this reason, even if the inner diameter reduced portion is lifted, the amount of the container body that is pulled out is reduced.

  If the heat insulating part of the container body is a vacuum heat insulating layer, that is, if the container body is a vacuum double container, the peripheral upper end of the inner cylinder and the outer cylinder are welded, and the peripheral lower end of the outer cylinder And the bottom plate will be welded. Conventionally, in order to ensure a heat insulation clearance between the outer cylinder, the inner cylinder, and the bottom plate after the lower side welding (welding to the bottom plate) of the outer cylinder, a bulge is formed on the upper side of the lower welded part of the outer cylinder. Is done as appropriate. If the bulging portion is an outer diameter enlarged portion, it is not necessary to add a molded part of the container body or attach another member.

  In the container body, in order to protect the heat insulating portion from below, a bottom member is fitted to the lower end portion of the outer peripheral diameter of the outer cylinder. If the outer diameter portion of the bottom member is the outer diameter enlarged portion, it is not necessary to add a molded part of the container body or attach another member.

The inner diameter reduction part of the container cover can be constituted by another member fixed to the inner surface of the peripheral cover part or another member inserted between the outer and inner linings of the peripheral cover part. Above all, it is preferable to use a separate member inserted between the outer cover and the inner lining of the peripheral cover portion, since it is difficult to visually observe the presence of the inner diameter reduced portion when the locking member is released or loosened to widen the peripheral cover portion. .
Here, if the cushioning material inserted between the outer cover and the inner cover of the peripheral cover portion is adopted as the separate member, the inner diameter reduced portion can be made into a common member or can be commonly assembled.

  By the way, in the design of the container cover, even if the configuration of the present invention is satisfied, the production error is unavoidable, and when mass-produced, there may be a slight variation in the pressing state of the inner diameter reduced portion between products. This variation becomes a problem particularly when the pressing state occurs on the loose side, and it is preferable that the variation can be corrected before the container cover is used.

The inner diameter reduced portion of the container cover is formed of an adjustment member having one circumferential end fixed to the circumferential cover portion and the other circumferential end is detachable, and the other circumferential end of the inner diameter reduced portion is the circumferential end. By adopting a configuration in which the circumferential fixing position to be attached to the side cover portion can be adjusted in a direction away from one end in the circumferential direction with the locking member removed, the variation on the side where the pressing condition is loosened is corrected. Is possible.
That is, the circumferential length of the circumferential cover portion can be maintained in a reduced state if the circumferentially fixed position where the other circumferential end of the inner diameter reduction portion is attached to the circumferential cover portion is moved away from the one end side. If the circumferential length of the circumferential cover portion is shortened, as a result, the position of the inner diameter reduced portion in the state of being fastened by the locking tool can be brought closer to the inner diameter side, and the variation can be corrected. When the variation is within the specified range, the peripheral cover portion can have a natural appearance.

  Further, as a means different from the adjusting member, if the inner diameter reducing portion of the container cover is constituted by an elastic contracting member attached to the circumferential cover portion along the circumferential direction, the contracting force in the circumferential direction of the inner diameter reducing portion As a result, the shrinkage in the circumferential direction is elastically given to the peripheral cover portion, and as a result, the position of the inner diameter reduction portion in the state of being fastened by the locking tool is closer to the inner diameter side, and the variation is corrected. Can do.

In addition, a hook fastener, a string, a slide fastener, a snap button, or the like can be used as the locking tool.
If the fastener is adjustable such as the hook-and-loop fastener in the circumferential direction of the circumferential cover portion, the variation can be achieved by adjusting the fastening position of the fastener. Can be corrected.
In addition to the configuration related to the adjustment member and the elastic contraction member, if the locking member having a constant circumferential fastening position such as the slide fastener is employed, the result of the variation correction is stabilized every time. This is preferable in terms of preventing omission.

  As described above, according to the present invention, an outer diameter enlargement portion having a maximum outer diameter larger than the inner diameter reduction portion of the container cover is provided on the lower peripheral side of the container body, and the inner diameter reduction is provided at a lower portion of the peripheral cover portion. The inner diameter reduced portion of the container cover is removed from the container body by adopting a configuration in which the inner diameter reduced portion is located on the upper side of the maximum outer diameter of the outer diameter enlarged portion in a state where the locking member is fastened. It is difficult to float, and the amount of the container body that is lifted upward can be reduced.

Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.
Drawing 1 (a) shows from the front in the state where a front lower part of a container for drinks with a cover concerning a 1st embodiment was partially notched. FIG.1 (b) shows the enlarged view of the notch part of said (a).
As shown in FIG. 1, the beverage container with a cover according to the first embodiment has a container body 10 having a heat insulating portion 13 between an inner cylinder 11 and an outer cylinder 12, and the container body 10 exposes an upper end opening / closing portion 14. And a container cover 20 that fits in the above state.

  The container body 10 is a vacuum double container in which the heat insulating portion 13 is a vacuum double layer. The upper ends of the inner cylinder 11 and the outer cylinder 12 are welded, and the lower ends of the outer cylinder 12 and the bottom plate 15 are welded. A bulging portion 16 is formed on the upper side of the lower welded portion of the outer cylinder 12, and a heat insulating clearance among the outer cylinder 12, the inner cylinder 11, and the bottom plate 15 is secured after the outer cylinder 12 and the bottom plate 15 are welded. A bottom member 17 is fitted on the outer periphery of the lower welded portion of the outer cylinder 12.

  The upper end opening / closing part 14 of the container body 10 is a lid structure part that is retrofitted to open and close the container mouth. In the container body 10, a shoulder cover member fitted to the outer diameter of the shoulder part of the outer cylinder 12, It consists of a lid set such as a lid and a stopper for opening and closing the container opening opened to the shoulder cover member. The mouth is exposed when the lid is opened. The container body 10 is a portable one that can be lifted by hand in the full state and can be attached to the drinking mouth. By tilting the container body 10, the internal beverage flows out from the drinking mouth. ing.

  A portion higher than the bulging portion 16 of the outer cylinder 12 does not exceed the maximum outer diameter of the bulging portion 16 and is formed in a cylindrical shape between the upper end opening and closing portion 14 and the shoulder cover member. During this time, it can also be formed in a downwardly expanding shape.

  The container cover 20 includes a bottom cover portion 21 on which the container body 10 is placed and a peripheral cover portion 22 that wraps the container body 10 from the outer diameter side, and the peripheral cover with the notch 23 of the peripheral cover portion 22 as a boundary. Both sides in the direction are fastened by the locking tools 24 and 25. This container cover 20 is formed by connecting each part by sewing.

  The bottom cover portion 21 is configured such that a difference in elastic deformation amount between when the container body 10 is placed in a full state and when the remaining amount of beverage is reduced falls within a certain range.

  FIG. 2 shows the state in which the locking members 24 and 25 are released, the peripheral cover portion 22 of the container cover 20 is opened, and the container body 10 is placed on the container cover 20 from above. FIG. 3 shows a state in which the peripheral cover portion 22 is fastened with the locking tool 24 from the state of FIG. FIG. 4 shows a state in which the peripheral cover portion 22 is fastened with the locking tool 25 from the state of FIG.

  As shown in FIG. 1 and FIG. 2, the circumferential cover portion 22 is formed with a cut portion 23 that is linearly continuous from the upper end to the lower portion at one place in the circumferential direction. Both sides in the circumferential direction with the notch 23 as a boundary can be widened outward so that the opening is larger than the maximum outer diameter of the bulging portion 16 of the container body 10. As shown in FIG. 3, the locking tool 24 is a slide fastener and can be fastened on both sides in the circumferential direction with the notch 23 as a boundary. In a state in which the locking tool 24 is fastened, the peripheral cover portion 22 has a rigidity that the inner surface closely follows the upper peripheral side of the container body 10, and the inner diameter thereof is the maximum outer diameter of the bulging portion 16. Is set to a negative radial dimension. For this reason, when the locking tool 24 is fastened, the inner surface of the circumferential cover portion 22 is pressed against the bulging portion 16 of the container body 10.

  The locking tool 25 is a hook-and-loop fastener and can fasten both sides in the circumferential direction at the upper part of the circumferential cover portion 22 as shown in FIG. The locking tool 25 enhances the tightening performance of the upper part of the peripheral cover part 22 and, in particular, considers that a suspension belt is attached to the upper part of the peripheral cover part 22, and the slider of the locking tool 24 is fixed. It is intended to prevent it from moving freely and can be omitted.

  In addition, an inner diameter reduction portion 26 that is pressed against the container body 10 by fastening the locking member 24 is provided on the circumferential cover portion 22. The inner diameter reduction part 26 is fixed on the lower inner surface of the circumferential cover part 22, and spans both sides of the locking tool 24 at the same height in the circumferential direction. The height of the inner diameter reduction portion 26 is a height that is pressed against a position higher than the maximum outer diameter of the bulging portion 16 regardless of the beverage remaining amount in the container body 10 and is higher than the lower end of the cut portion 23. Is set to a position. The radial thickness of the inner diameter reduction part 26 reduces the inner diameter of the peripheral cover part 22 at the bulging part 16 of the container body 10. The bulging portion 16 on the lower peripheral side of the container body 10 becomes an outer diameter enlarged portion whose maximum outer diameter is larger than the inner diameter at the inner diameter reducing portion 26.

  The bulging portion 16 of the container body 10 extends over the entire circumference of the outer cylinder 12. For this reason, when the locking tool 24 is fastened, the inner diameter reduction part 26 is positioned above the maximum outer diameter of the bulging part 16 regardless of the relative positional relationship between the container body 10 and the container cover 20 in the circumferential direction. As described above, since the original inner diameter of the inner surface fabric of the peripheral cover portion 22 is set to be pressed against the bulging portion 16, the inner diameter reducing portion 26 is inclined when the locking tool 24 is fastened. Pressed firmly against the part.

  In addition, when the container body 10 is put in the container cover 20, the inner diameter reduction part 26 and the maximum outer diameter of the container body 10 may be in the above relationship. In this first embodiment, since the relative positional relationship in the circumferential direction when the container body 10 is put into the container cover 20 is not determined, either the inner diameter reducing portion 26 or the maximum outer diameter of the container body 10 is the total length in the circumferential direction. As long as the above relationship is satisfied, the maximum outer diameter of the inner diameter reduction portion 26 and the container body 10 are intermittently provided in the circumferential direction, or only the inner diameter reduction portion 26 is provided around the circumference of the circumferential cover portion 22. It can also be provided over the entire length in the direction. In the first embodiment, both the inner diameter reduced portion 26 and the maximum outer diameter of the container body 10 are extended over the entire length in the circumferential direction, and the entire length is utilized to prevent the removal.

  Further, another member constituting the inner diameter reduction part 26 is a material that can be deformed following the shape of the container body 10 such as rubber, silicon, etc., and has a larger friction coefficient than the inner surface fabric of the circumferential cover part 22. Thus, the anti-slip performance is improved. When the inner diameter reduction part 26 having such a large friction coefficient is located at a position lower than the lower end of the notch part 23 of the circumferential cover part 22, there is a concern that the container part 10 may be caught by the bulging part 16 when being put in and out. In this 1st Embodiment, since it exists in a position higher than the lower end of the notch part 23, there is no worry.

The beverage container with a cover according to the first embodiment has the above-described configuration, and the latches 24 and 25 are released to open the peripheral cover portion 22 of the container cover 20 so that the container body 10 can be easily opened. Put on the bottom cover portion 21 and securely remove the bottom of the container body 10 with the bottom cover portion 21, tighten the peripheral side of the container body 10 with the peripheral side cover portion 22, and press the inner diameter reduction portion 26. Therefore, it is possible to prevent the container body 10 from being pulled out upward.
Since the inner diameter reduction part 26 is at the lower part of the peripheral cover part 22 and is located on the difficult deformation side close to the bottom cover part 21, when the fastening tools 24, 25 are tightened or loosened, the inner diameter reduction part 26 becomes the container. It is difficult to float from the body 10.
When the container body 10 is placed on the bottom cover portion 21, the vertical position relationship of the container body 10 with respect to the container cover 20 is determined by the bottom cover portion 21. When the locking tools 24 and 25 are fastened together, the inner diameter reduction part 26 at the lower part of the peripheral cover part 22 and the bulging part 16 on the lower peripheral side of the container body 10, that is, the maximum outer diameter of the outer diameter expansion part The inner diameter reduction part 26 is pressed to a position near the upper side of the maximum outer diameter of the bulging part 16. For this reason, even if the inner diameter reduced portion 26 is lifted, the amount of the container body 10 that is pulled out is reduced.
Since the bulging portion 16 of the outer cylinder 12 is an outer diameter enlarged portion, there is no need to add a molding part of the container body 10 or attach another member only for the purpose of obtaining the outer diameter enlarged portion.

Next, a second embodiment of the present invention will be described with reference to FIG. In the following, differences from the first embodiment will be mainly described, and description of the same configuration will be omitted.
As shown in FIG. 5, the peripheral cover portion 30 of the container cover according to the second embodiment has an outer layer 31, an inner layer 32, and a cushion material 33 put between the outer layer 31 and the inner layer 32. ing. The cushion material 33 is formed by stacking a belt-like thickness increasing sheet on a planar main body sheet, and is fixed between the outer lining 31 and the lining 32. As a result, the lining 32 bulges toward the inner diameter side by the cushion material 33, and an inner diameter reduction portion that is pressed against the bulging portion 16 of the container body 10 by the lining 32 and the cushion material 33 is formed. That is, in the second embodiment, the inner diameter reduced portion and the cushion material 33 can be formed into a common member or can be assembled.

Next, a third embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 6, the third embodiment is such that the outer diameter portion of the bottom member 41 fitted to the lower end portion of the outer diameter of the outer cylinder 12 of the container body 40 has an outer diameter larger than that of the outer cylinder 12. The diameter is enlarged. For this reason, this 3rd Embodiment does not add the formation part of the container body 40, or attach another member only for the purpose of obtaining an outer diameter expansion part.

Next, a fourth embodiment of the present invention will be described with reference to FIG.

Between the cut portions 53 of the peripheral cover portion 52, belt loops 54 are formed by slitting at a plurality of locations in the circumferential direction of the lining of the peripheral cover portion 52. The inner diameter reduction portion 55 is configured by a belt-shaped adjustment member that is fixed to the circumferential cover portion 52 at one end in the circumferential direction and that can be attached and detached with a locking tool 56 at the other circumferential end. The locking tool 56 is adjustable in a direction in which the circumferential fixing position where the other circumferential end of the inner diameter reducing portion 55 is attached to the circumferential cover portion 52 is away from the circumferential one end. In the fourth embodiment, It is said to be a hook fastener. In FIG. 7A, a solid line indicates a state where the inner diameter reduction portion 55 is in a natural state, and a state where the circumferential fixing position of the locking tool 56 is away from one end side in the circumferential direction is indicated by a two-dot chain line. With the slide fastener of the notch 53 removed, as shown by a vector line in the drawing, the other end in the circumferential direction of the inner diameter reducing portion 55 is pulled to one end, and the peripheral cover portion 52 is attached by the locking tool 56. If the circumferential fixing position is farther from the circumferential end than the natural state, the circumferential length of the circumferential cover 52 is shortened and wrinkles are shifted, and the state can be maintained. As a result, the position of the inner diameter reducing portion 55 is brought closer to the inner diameter side in a state where the circumferential cover portion 52 is fastened by the slide fasteners on both sides of the cut portion 53. This fourth embodiment can eliminate the variation in the circumferential length associated with the sewing of the container cover by utilizing this, and when the variation is within the specified range, the circumferential cover 52 is naturally free of wrinkles. Appearance can be made.

Next, a fifth embodiment of the present invention will be described with reference to FIG.
