Description

  The present invention relates to a holder that is stacked on the outer periphery of a container.

  Paper or resin disposable containers that contain hot liquids such as coffee and cold liquids such as beer are well known. In order to avoid taking up space during storage, this type of container has a trunk portion that gradually increases in diameter upward and can be stacked.

If the container is kept holding a high-temperature liquid in the container, the heat of the liquid is transferred to the hand through the container body and cannot be held for a long time.
On the other hand, if the container is kept holding a low-temperature liquid in the container, the heat of the hand is transferred to the liquid through the container body. In addition, water droplets condensed on the container body wets the hands.
In order to prevent the above inconvenience, various heat-insulating holders that are stacked on the outer periphery of the body of the container have been proposed.

  The simplest holder is a paper tube. The diameter of the holder gradually increases upward, and the inclination with respect to the central axis is substantially equal to the inclination of the container body. However, such a paper holder has an insufficient heat insulation effect.

In order to improve the heat insulation performance of the holder, Patent Document 1 proposes a holder using corrugated paper. However, the use of corrugated paper increases the manufacturing cost.
Patent Document 2 proposes a holder in which a plurality of tongue pieces are provided on the inner peripheral surface at intervals in the circumferential direction in order to stably hold the container (see FIG. 4). This tongue also appears to serve as a spacer for forming a heat insulating space between the holder and the container. However, since this holder attaches a plurality of tongue pieces, the manufacturing cost increases.

Patent Document 3 proposes a belt-like holder formed by molding a resin sheet. This holder has a constant width and extends in an arc shape, a convex portion for connection is formed at one end, and a hole for connection is formed at the other end. Further, the holder is formed with a large number of supporting convex portions at intervals in the direction in which the band extends. These support convex portions extend linearly perpendicular to the direction in which the belt extends.
The belt-shaped holder has a cylindrical shape whose diameter gradually expands upward by fitting a convex portion at one end into a hole at the other end and connecting both ends, as in the first and second patent documents. It is attached to the container body. In this mounted state, when the support convex part hits the outer peripheral surface of the container body part, a heat insulating space is formed between the holder and the container body part.

JP 2004-168345 A JP 2007-37869 A JP 2007-145342 A

  Since the holder of Patent Document 3 is obtained by molding a resin sheet, the manufacturing cost can be reduced as compared with the paper holders of Patent Documents 1 and 2, but both ends of the belt are connected when being attached to a container. Work was necessary and the mounting work was complicated.

The present invention was made to solve the above problems, and in a container holder that is stacked on a cylindrical container body whose diameter gradually increases upward,
Molded resin sheet,
A cylindrical main body portion whose diameter gradually increases toward the upper side, and an annular reinforcing portion that continues to the entire circumference of the upper end edge of the main body portion and projects radially outward from the upper end edge,
The main body portion has a plurality of support convex portions that are formed at intervals in the circumferential direction and project radially inward, and the support convex portions abut on the container body portion, whereby the main body portion and the A heat insulating space having an open upper end is formed between the container body and the container body.

According to the said structure, since a container holder is obtained by shape | molding a resin sheet, manufacturing cost can be reduced.
Since the main body has a cylindrical shape, preparation work for attachment to the container body is not necessary, and the attachment work can be facilitated.
Since the cylindrical shape of the main body can be held by the annular reinforcing portion protruding radially outward, the container holder can be stably stacked, and the mounting operation to the container can be performed more smoothly. .
Since the heat insulation space is formed between a main-body part and the said container trunk | drum by the several support convex part which left | separated in the circumferential direction contact | wins a container trunk | drum, heat insulation performance is securable. Furthermore, since the upper end of this heat insulation space is opened, when the contents of the container are hot, the heat can be released.
Further, since the container holder is formed by molding a resin sheet, it can be elastically deformed, and a soft feeling and a fit feeling can be obtained when it is held by hand.

Preferably, the support convex portion extends in the vertical direction to reach the lower end of the main body portion, and a bridging portion is formed between the lower ends of the adjacent support convex portions, and the bridging portion is a lower end of the adjacent support convex portion. It is connected with the lower end edge of the wall part of the said main-body part located between an edge and these support convex parts.
According to this structure, since the adjacent support convex parts are connected by the bridging part, the support convex parts can be prevented from being crushed so as to spread each other, and the heat insulating space can be favorably maintained.

Preferably, the inner peripheral edge of the bridging portion forms an arc and is disposed along an inscribed circle at the lower end of the support convex portion.
According to this configuration, when the contents in the container are cold, the water droplets condensed on the container body can be received by the bridging portion, and the water droplets can be prevented from falling from the container.

Preferably, the support convex portion extends linearly over the entire axial length of the main body portion.
According to this structure, the heat insulation space formed between support convex parts also becomes linear, and the hot air collected in the heat insulation space can be escaped smoothly. In addition, the region where the support convex portion comes into contact with the container body portion can be ensured to the maximum, and the heat insulating space can be stably maintained even under pressure from the hand.

Preferably, the reinforcing part is thicker than the main body part.
According to this configuration, the cylindrical shape of the main body can be maintained more stably.

Preferably, the reinforcing portion includes a first flange portion protruding radially outward from an upper end edge of the main body portion, a cylindrical upright portion rising from an outer peripheral edge of the first flange portion, and a A second flange projecting radially outward from the upper edge.
According to this configuration, the reinforcing portion has two flange portions, and the cross-sectional shape thereof is a bent shape through the upright portion, so that the strength of the reinforcing portion can be increased, and consequently the cylindrical shape of the main body portion. Can be maintained more stably.

Preferably, the inner diameter of the second collar part is smaller than the outer diameter of the first collar part.
According to this configuration, the container holder can be stacked at intervals corresponding to the height of the upright portion, and the container holder can be easily taken out from the stacked state.

  Since the container holder of the present invention is inexpensive, has high heat insulation performance, and can maintain a good cylindrical shape, it can be stably stacked and can be smoothly attached to the container.

  Hereinafter, the container holder concerning this invention is demonstrated, referring drawings. The container holder which concerns on this invention is obtained by shape | molding the sheet | seat which consists of thermoplastic resins by pressure forming, vacuum forming, etc. The resin material is HIPS (high impact styrene), PP (polypropylene), A-PET (polyethylene terephthalate), PPF (with polypropylene talc), or the like.

1 to 9 show a container holder 1 according to a first embodiment of the present invention.
As shown in FIGS. 1 and 2, the container holder 1 is formed in a cylindrical shape and has a main body portion 10 having an upper end opening and a lower end opening, and is connected over the entire circumference of the upper end edge of the main body portion 10. And an annular reinforcing portion 20 protruding outward.

The main body 10 has a so-called trumpet shape (truncated cone shape), and the diameter gradually increases from the lower end to the upper end so as to be inclined at a constant angle with respect to the central axis L.
As shown in FIGS. 2 and 3, the main body 10 has a plurality of support protrusions 11 that are formed at intervals in the circumferential direction and protrude in the radially inward direction. In the present embodiment, these support convex portions 11 have a triangular cross section and extend linearly over the entire axial length of the main body portion 10.
In the main body 10, the wall 12 positioned between the support protrusions 11 forms a cross-sectional arc.

The linear ridge line part 11a (radial inner end) of the support convex part 11 serves as a contact part to the container 50 as described later. The wall portion 12 is a portion that comes into contact with the hand when the user grips it with the hand. In the present embodiment, the ridge line part 11 a and the wall part 12 are inclined at the same angle with respect to the central axis L.
The virtual cylinder surface inscribed in the plurality of ridge line portions 11a gradually increases in diameter toward the upper side, and coincides with the outer peripheral surface of the trunk portion 51 of the container 50 described later.

  As shown in FIG. 4 and FIG. 5, the annular reinforcing portion 20 includes an annular first flange portion 21 that extends over the entire circumference of the upper end edge of the main body portion 10 and protrudes radially outward. An upright portion 22 having a short cylindrical shape that continues to the outer peripheral edge of the portion 21, a second flange portion 23 that protrudes radially outward from the upper end edge of the upright portion 22, and an obliquely downward direction from the outer peripheral edge of the second flange portion 23 And a drooping portion 24 protruding from the bottom. In the present embodiment, the first flange portion 21 and the second flange portion 23 are perpendicular to the central axis L and are horizontal.

Contrary to the main body 10, the upright portion 22 gradually decreases in diameter from the lower end to the upper end, and the upper end diameter is smaller than the lower end diameter. In other words, the inner diameter of the second flange 23 is smaller than the outer diameter of the first flange 21.
The container holder 1 is stacked as shown in FIG. 4 in a state in which the support protrusions 11 are aligned. In this stacked state, the first brim part 21 of the upper container holder 1 (shown by a solid line) is placed on the second brim part 23 of the lower container holder 1 (shown by an imaginary line). It is separated in the axial direction by the height of the portion 22.

As shown in FIGS. 2 and 6, the container holder 1 of the present embodiment has a horizontal bridging portion 30 between the lower ends of adjacent support convex portions 11. The bridging portion 30 is continuous with the lower end edge of the adjacent support convex portion 11 and the lower end edge of the wall portion 12 located between the support convex portions 11.
The inner peripheral edge 30 a of the bridging portion 30 forms an arc and is disposed along the inscribed circle of the ridge line portion 11 a of the support convex portion 11. More specifically, the inner peripheral edge 30a of the bridge portion 30 is on the inscribed circle. That is, these inner peripheral edges 30a have the same diameter as the inscribed circle. In addition, the diameter of these inner peripheral edges 30a may be smaller than the diameter of the inscribed circle.

The container holder 1 is obtained by molding a resin sheet as described above. After molding, the central part is punched out into a circular shape to form the inner peripheral edge 30a of the bridging part 30, and the outer peripheral edge of the hanging part 24 is cut to separate the container holder 1 from the resin sheet.
Although not clearly shown in the figure, the reinforcing portion 20 is twice or more thicker than the main body portion 10 and the bridging portion 30. For example, a resin sheet having a thickness of 0.3 to 0.7 mm is used, the thickness of the reinforcing portion 20 is 0.2 to 0.6 mm, and the thickness of the main body portion 10 and the bridging portion 30 is 0.1 to 0. 3 mm. The difference in thickness is inevitably obtained by pressure forming or vacuum forming of a resin sheet.

  The container holders 1 having the above configuration are taken out one by one from the stacked state shown in FIG. 4 and mounted so as to overlap the outer periphery of the paper or resin container 50 as shown in FIGS. The A high-temperature liquid such as coffee is poured into the container 50 in tandem with the mounting of the container holder 1.

  In the stacked state of the container holders 1, the container holders 1 can be maintained in the axially separated state by the height of the upright portion 22, so that the container holders 1 are not tightly fitted to each other, and the removal operation is performed smoothly. It is.

  The reinforcing portion 20 protrudes in the radial direction from the upper end edge of the main body portion 10 and has an annular shape, is thicker than the main body portion 10, has two flange portions 21 and 23, and has an overall cross-sectional shape. By forming the bent shape, the annular state can be stably maintained, and as a result, even when the main body 10 is formed thin, it can be stably maintained in a cylindrical shape. Therefore, the stacked state can be stably maintained, and the work of taking out from the stacked state and mounting it on the container 50 can be performed smoothly.

As shown in FIGS. 7 and 8, the container 50 includes a body portion 51, a bottom portion 52 that closes the lower end of the body portion 51, and an opening edge portion 53 that is a rounded upper end edge of the body portion 51. ing.
The diameter of the body 51 gradually increases from the lower end toward the upper end. The inclination angle of the body portion 10 of the container holder 1 is substantially equal to the inclination angle of the body portion 51. More specifically, the virtual cylindrical surface inscribed in the ridge line portion 11 a of the support convex portion 11 of the container holder 1 substantially coincides with the outer peripheral surface of the trunk portion 51. Thereby, in the mounting state of the container holder 1, the ridge line part 11 a of the support convex part 11 of the container holder 1 is in a state where the outer peripheral surface of the body part 50 is in contact with the entire length. Therefore, the container 50 can be stably held via the container holder 1.

  As described above, since the support convex portion 11 of the container holder 1 hits the outer peripheral surface of the barrel portion 51 of the container 50, the heat insulating space 15 is interposed between the adjacent support convex portion 11, the wall portion 12, and the barrel portion 51 of the container 50. The heat of the liquid in the container 50 can be prevented from being transmitted to the hand holding the container holder 1 in a short time, and can be carried without feeling pain. Moreover, since these heat insulation spaces 15 are linear in the vertical direction and their upper ends are open, hot air can be released well, and heat transfer to the hand can also be delayed from this point.

  When the bridging part 30 of the said container holder 1 connects the adjacent support convex part 11, the distance between the lower ends of the adjacent support convex part 11 can be maintained substantially constant. Therefore, in the mounting state of the container holder 1 on the container 50, the adjacent support convex portions 11 can be prevented from being crushed so as to widen the interval, and the heat insulating space 15 can be secured.

  The container 50 may contain a liquid such as cold beer or ice cream. In this case, by superimposing the container holder 1 on the container 50, it is possible to prevent the heat of the hand from being transmitted to the stored item, and to prevent water droplets condensed on the outer peripheral surface of the body 51 of the container 50 from getting on the hand. it can.

  When the container holder 1 is mounted on the container 50, the inner peripheral edge 30 a of the bridging portion 30 of the container holder 1 is in contact with the outer peripheral surface of the trunk portion 51 and closes the lower end of the heat insulating space 15. Therefore, as described above, when the contents in the container 50 are low temperature, even if water droplets condensed on the outer peripheral surface of the body 51 of the container 50 move downward along the body 51, the water is received by the bridge 30. The water droplets can be prevented from falling from the container 50.

  Since the main body 10 of the container holder 1 is formed of a resin sheet and can be elastically deformed, a fit and soft feeling that stick to the finger when held are obtained. In particular, in this embodiment, since it is thin, it is possible to further enhance the fit and soft feeling. The inventor considered the conditions for obtaining the fit and the soft feeling while securing the heat insulating space 15.

(Condition 1)
In order to obtain a fit and sufficiently secure the heat insulating space 15, it is preferable that the width b of the wall portion 12 in direct contact with the finger is equal to or greater than the width a of the support convex portion 11 in which the finger does not contact.
b ≧ a (1)

  As shown in FIGS. 10A and 10B, when the person grasps the container holder 1 attached to the container 50, the most force is applied to the thumb and the fingertip of the index finger and / or middle finger. This pressure application region R is between the position retracted 5 mm from the tip of the finger and the vicinity of the first joint. Since the length of the pressure application region R includes the difference between the thumb, forefinger, middle finger, and individual differences, the maximum value is Lmax and the minimum value is Lmin.

(Condition 2)
If the width b of the wall portion 12 is too wide, the pressure applying region R applies pressure only to one wall portion 12, and the heat insulating space 15 may be crushed. Therefore, when the pressure application region R is in contact with only one wall portion 12, it is preferable that a part of at least one adjacent wall portion 12 touches the finger when the wall portion 12 is elastically deformed to some extent. This condition can be satisfied even when the length of the pressure application region R is at the minimum value Lmin. This is expressed by the following formula.
Lmin ≧ 2a + b (2)

(Condition 3)
On the other hand, as the number of wall portions 12 with which the pressure application region R is in contact increases, the pressure is dispersed, and the elastic deformation of the wall portions 12 becomes insufficient, and a feeling of fit and softness cannot be sufficiently obtained. Therefore, when the pressure application region R is in contact with the entire width of the two wall portions 12, when these two wall portions 12 are elastically deformed, the two wall portions 12 adjacent to the left and right are not simultaneously in contact with each other. Is preferred. This condition can be satisfied even when the length of the pressure application region R is at the maximum value Lmax. This is expressed by the following formula.
Lmax ≦ 3a + 2b (3)

  The above conditions (2) and (3) ensure that the pressure applying region R always applies pressure to the two or three wall portions 12, and the heat insulating space 15 is increased by appropriate elastic deformation of the wall portions 12. A feeling of fit and softness can be obtained without being crushed.

  The maximum length Lmax of the pressure application region R is set to 24 mm and the minimum length Lmin is set to 20 mm, and the width a of the support convex portion 11 and the wall portion 12 are set so as to satisfy the above conditions (1) to (3). Width b is determined.

In the present embodiment, the width a of the support convex portion 11 of the container holder 1 is 5 mm over the entire length, and the width b of the wall portion 12 is gradually increased upward to have a lower end of 5 mm and an upper end of 7 mm. Therefore, the said conditions (1)-(3) are satisfied over the full length of the main-body part 10. FIG.
When the container holder 1 is held with the container holder 1 mounted on the container 50, it is generally held in an intermediate region excluding the vicinity of the upper end and the vicinity of the lower end of the main body 10. The above conditions (1) to (3) may be satisfied only by this gripping region.

Next, another embodiment of the present invention will be described. In these embodiments, constituent parts corresponding to those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
In the second embodiment shown in FIG. 11, the support convex portion 11 does not extend to the upper end of the main body portion 10. Therefore, an annular heat insulating space 16 is formed between the upper end portion of the wall portion 12 of the main body portion 10 and the trunk portion 51 of the container 50. In this embodiment, the upper end of the heat insulating space 15 extending linearly is connected to the heat insulating space 16 and the lower end is opened.

  In 3rd Embodiment shown in FIG. 12, instead of each support convex part 11 extended continuously over the full length of the main-body part 10 like 1st Embodiment, several support convex part 111 formed in the up-down direction was formed. have. The virtual cylinder surface inscribed in the upper end corner portion 111a (container contact portion) of the support convex portion 111 is equal to that in the first embodiment. Between the rows of support convex portions 111 adjacent in the circumferential direction, a heat insulating space 115 linearly extending in the vertical direction is formed. The upper end and the lower end of the heat insulation space 115 are open.

The present invention is not limited to the above embodiment, and various aspects can be adopted.
In the first and second embodiments, the support protrusion 11 has a triangular cross-sectional shape, but may have a semicircular arc shape, a trapezoidal shape, or the like.
In 1st, 2nd embodiment, although the cross-sectional shape of the wall part 12 located between the support convex parts 11 has comprised the circular arc, it may be linear form.

  The present invention can be applied to a holder of a container that contains a hot or cold liquid or the like.
