In particular, the present invention relates to a bottle with a handle that allows a handle to be reliably and easily attached to a large-capacity bottle, is easy to hold, and is easy to pour contents.

[Problems to be Solved by Prior Art and Invention]

Biaxially stretched blow molded bottles made of saturated polyester resin typified by polyethylene terephthalate have excellent transparency and surface gloss, and are beautiful, gas barrier, water impermeability, content resistance and storage. It has excellent properties. In addition, it does not generate toxic gas in additives such as plasticizers and stabilizers, generates little heat during combustion, and does not damage the furnace. Therefore, it is widely used in various drinking water, seasonings, bottles for alcoholic beverages and other foods.

In addition, since this type of bottle is lightweight and has high mechanical strength, it is suitable for use as a large-sized bottle, and recently, it has been put into practical use as a large-sized bottle having an inner volume far exceeding 1. There is.

However, when the contents such as beverages are filled into such a large bottle, the weight becomes considerable, and it is inconvenient to hold the bottle when trying to take out the contents little by little on the table. There is.

Therefore, it is conceivable to attach a handle to the bottle to make it easier to hold, but it is extremely difficult to integrally form the handle in the above-mentioned biaxially stretch blow-molded bottle.

Therefore, a method in which a handle manufactured in a separate process is attached to a blow-molded bottle body to form a bottle with a handle is generally adopted, and various bottles with a handle have been proposed so far.

For example, there is a bottle in which the handle is attached to the neck of the bottle by screwing, but this is troublesome to attach the handle,
In addition, the mounting position of the handle on the bottle is not constant due to the strength of tightening. Further, the handle once attached may be relatively easily detached, which is not preferable.

Further, various bottles have been proposed in which fitting parts such as protrusions and recesses are provided on the bottle body and the handle, and thereby the handle is mechanically attached.

However, the size of bottles is increasing,
Large-scale bottles with contents of 1 or 2 liters or more are being put into practical use, and even in such large-sized bottles, firm attachment can be maintained, and a handle can be easily attached to the bottle body during bottle production. A bottle with a handle that can be used is desired.

Therefore, an object of the present invention is to provide a bottle with a handle, which has a sufficient strength even for a large-sized bottle and which is surely and easily attached.

[Means for Solving the Problems]

As a result of earnest research in view of the above-mentioned object, the present inventor has found that the bottle body has a support ring having a plurality of radially expanded portions and an expanded portion below the support ring, which is engaged with the bottle body. As the handle member, a handle member having a ring portion that is an engaging portion and a handle integrally formed, and provided with a protrusion having a recess on the upper surface on the inner wall surface of the ring portion is used, and the ring portion is a bottle. By mounting the mouthpiece on the main body and then rotating it, the tip of the radially expanded portion is fitted into the recess of the ridge, and it projects into the gap between the radially expanded portion of the support ring and the expanded portion. The present invention was discovered by discovering that the handle member can be firmly fixed to the bottle main body if the striations are engaged with each other, and the present invention has been made.

That is, in the bottle with a handle of the present invention, (a) a bottle body in which an enlarged diameter portion is formed below a support ring having at least two radially enlarged portions, (b) a ring portion, and the ring. And a handle integrally formed with the handle, wherein the inner wall portion of the ring portion has circumferentially formed protrusions in the same number as the number of radially expanded portions of the support ring. The upper surface of the protruding portion has a recess and gradually rises on at least one side of the recess, and the thickness of the protruding portion in the recess is equal to that of the support ring of the bottle body. The handle member is attached to the mouth of the bottle body and then rotated, so that the tip end portion of the radially expanded portion of the support ring has the protrusion. Article Of fitted in the recess, said handle member having characterized by comprising been firmly secured to the bottle body.

[Examples and functions]

The present invention will be described in detail below based on embodiments with reference to the accompanying drawings.

FIG. 1 is a partially exploded perspective view of a bottle with a handle according to an embodiment of the present invention.

The bottle is a bottle body 1 manufactured by biaxial stretch blow molding.
And a handle member 5 manufactured by another process such as injection molding
Consists of.

The bottle body 1 is composed of a mouth portion 2, a shoulder portion 3 and a body portion 4, and has a support ring 21 having two radially expanded portions at a lower portion of the mouth portion 2. In this embodiment, since the support ring 21 is provided with the two expanded diameter portions, the cross section of the support ring 21 is substantially elliptical or oval. Further, at the lower part of the support ring 21, a cylindrical expanded diameter portion 22 is formed extending to the upper end of the shoulder portion. The cylindrical expanded portion 22 is a portion integrally formed when the bottle body 1 is stretch blow-molded, and is formed coaxially with the bottle body 1. In addition, a concave portion 31 having a flat surface and a smooth curved surface is provided on one side surface of the shoulder portion of the bottle body 1, and when the handle member is attached to the bottle body, the handle is positioned in the concave portion 31 to grip the handle. It is easy to do.

Next, the handle member 5 includes a handle 51 and a cylindrical ring portion 52. The inner diameter of the ring portion 52 is slightly larger than that of the enlarged diameter portion 22 provided on the bottle body 1. At the upper part of the inner wall surface of the ring portion 52, a pair of ridges are provided at opposite positions.
53, 53 are provided. Each protruding portion 53, 53 is a ring portion 52.
Has a recess 53b that receives the tip of the support ring 21 at approximately the center of its upper surface. In this embodiment, both side portions 53a, 53a of the recess 53b of the protrusion 53 have an upper surface that gradually rises toward the recess 53b, but only one side may have an upper surface that rises. . In that case, the other side may have a shape that is short in the circumferential direction.

At the position of the recess 53b, the protruding portion 53 has a thickness substantially equal to the distance between the tip end portion of the enlarged diameter portion of the support ring 21 and the cylindrical enlarged diameter portion 22 described above. Therefore, as will be described later, the tip of the support ring 21 has a recess 53 of the protrusion 53.
When fitted into b, the recess 53b of the protrusion 53 is firmly held by the lower surface of the support ring 21 and the upper surface of the expanded diameter portion 22.

The handle 5 is attached to the bottle body 1 described above as follows. First, as shown in FIG. 1, the outer peripheral portion of the support ring 21 in the longitudinal direction and the ridges 53, 53 of the ring portion 52.
Attach the ring part 52 from above the mouth part 2 so that
The lower surfaces of the pair of protrusions 53, 53 are brought into contact with the upper surface of the expanded diameter portion 22.

Next, move the handle member 5 around the center axis of the bottle body 1
° rotate. When the handle member 5 starts to rotate, the end portion 53a of the protrusion 53 enters the gap between the tip end portion of the radially expanded portion of the support ring 21 and the expanded portion 22. As described above, the end portion 53a has a shape in which the upper surface gradually rises toward the recess 53b (thickens gradually), so that the rotation of the handle member 5 is restricted before reaching the recess 53b. . However, since the support ring 21 is elastically deformable, the support ring 21
21 gets over the end 53a. Finally, the tip end portion of the radially expanded portion is fitted into the recess 53b of the protrusion 53. At the same time, the protrusion 53 fits into the gap between the radially expanded portion of the support ring 21 and the radially expanded portion 22.

FIG. 2 is a plan view showing a state where the bottle body 1 and the handle member 5 shown in FIG. 1 are engaged with each other. The two distal end portions of the radially expanded portion of the support ring 21 are respectively in contact with the upper surfaces of the projecting ridge portions 53, 53 (hatched portions in the drawing) provided on the ring portion 52 and facing each other. The tip end portion of the radially expanded portion is fitted between the end portions 53a, 53a. That is, the support ring 21 is laterally fixed by the four ends.

FIG. 3 is a partial sectional view taken along the line AA of FIG. As can be seen from the figure, the protruding portion 53 is fitted in the gap formed by the support ring 21 and the enlarged diameter portion 22. Further, a portion of the inner wall surface of the ring portion 52 below the protruding portion 53 substantially abuts the side surface of the enlarged diameter portion 22. Further, the lower end surface of the ring portion 52 is in contact with the circumferential portion 23 formed around the lower end portion of the expanded diameter portion 22.

FIG. 4 is a partial cross-sectional view of the bottle shown in FIG. 3 as seen from the direction B in FIG. The lower portion of the inner wall surface of the ring portion 52 substantially abuts the side surface of the enlarged diameter portion 22, and the lower end surface of the ring portion 52 contacts the circumferential portion 23 formed around the lower end portion of the enlarged diameter portion 22. Touching.

With the handle attaching structure as described above, the attaching operation of the handle member 5 to the bottle body 1 becomes easy, and the handle member 5 once attached is not detached, so that the handle is surely attached. You can get a bottle. For example, when the bottle is lifted while carrying the handle 51, the weight of the bottle is received by the upper surfaces of the protrusions 53, 53 that are in contact with the lower surface of the radially expanded portion of the support ring 21. Another handle
Even if the bottle is tilted while gripping 51, the engaging portions between the protrusions 53, 53 and the gap formed by the support ring 21 and the enlarged diameter portion 22 and the side surface of the enlarged diameter portion 22 and the inner wall surface of the ring portion 52. Since the load is applied at the joint surface with, the bottle will not wobble. Further, since the tip end portion of the radially expanded portion of the support ring 21 is held by the end portions 53a, 53a from both sides, the handle member 5 does not rotate with respect to the bottle body 1. Even if a downward force is applied to the handle member 5, the contact surface between the lower end surface of the ring portion 52 and the circumferential portion 23 of the bottle body 1, the lower surface of the protruding portions 53, 53, and the upper surface of the expanded diameter portion 22. There is no problem because it is received at the contact surface.

Although the present invention has been described above with reference to the accompanying drawings with respect to a bottle having a support ring having two radially expanded portions, the present invention is not limited to this and is within the spirit of the present invention. Various changes can be made.

For example, the number of radially expanded portions of the support ring is not limited to two and may be three or more. When the number of radially expanded portions of the support ring is 3, it is possible to use a support ring 60 having a shape as viewed from above, for example, a shape schematically shown in FIG. At this time, three protrusions 62, 62, 62 are provided on the inner wall surface of the ring portion 61 of the handle member so as to correspond to the tips of the three radially expanded portions of the support ring 60. It should be noted that both ends of each protruding portion 62 are end portions 63 having the same shape as the above-described embodiment. Then, as shown in FIG. 5, the ring portion 61 is attached to the mouth of the bottle body, and then the ring portion 61 is rotated to attach the tip portions 60a, 60a, 60a of the three radially expanded portions to the respective ridges. It is fitted between both ends of 62 to engage the bottle body and the handle member.

As described above, in the present invention, the support ring having the three radially expanded portions can be provided, but the structure may be such that the number of radially expanded portions of the support ring is increased.

Further, not only the shape of the support ring, but also the shape of the handle or the shape of the concave portion of the bottle body shoulder can be appropriately changed.

[Effect of device]

As described above in detail, according to the present invention, the handle can be attached to the bottle extremely easily and securely,
Once attached, the handle does not come off from the bottle body.

The bottle with a handle of the present invention can easily pour the contents by simply grasping the handle, and even a large bottle is sufficiently durable to grasp and lift or tilt the handle only. It is a structure to get. Therefore, the bottle of the present invention can be applied to a large capacity PET bottle or the like.
