Description

  The present invention relates to a bellows-type telescopic straw attached to a pack container filled with beverages such as juice and milk and used for drinking.

  This type of bellows-type telescopic straw has a pair of inner and outer straws with different diameters slidably pulled out, and the insertion tip of the inner small diameter straw is disposed so as to protrude from the outer large diameter straw. The bellows bent portion is arranged in the middle in the longitudinal direction of the straw, and generally, the bellows bent portion is adhesively fixed to the wall surface of the pack container in the state of individual film packaging. Therefore, the customer removes it from the pack container, takes out the straw from the individual packaging film, slides the inner small diameter straw from the outer large diameter straw, expands the whole, and then attaches it to the seal portion of the pack container. The insertion tip of the inner narrow straw is inserted and used to suck and drink the filled beverage in the pack container.

  In this case, the bellows type telescopic straw can be compactly attached to the pack container in a contracted state due to its stretchability, and since the bellows bend is attached, the straw is bent with respect to the pack container. In general, the straw attached to the pack container in a film-packed state has a length of about 5 to 10 cm, for example. Since the insertion tip is protruded by about 0.5 to 1.5 cm, for example, the longitudinal direction of the outer thick-axis straw When trying to slide the handle by holding both ends, the bellows bent portion at the middle in the longitudinal direction of the outer thick shaft straw is stretched in response to the pulling force, so that the inner narrow stroke is extended. Chromatography is then retracted to the outside of the thick shaft in straw, the whole according to this and straw slide drawer extension becomes difficult and liable straw trouble that straw pack container attached unusable.

  The present invention has been made in view of such circumstances, and the problem to be solved is to be able to prevent the straw trouble that the inner small-diameter straw immerses into the outer large-diameter straw when pulling out the slides. To provide a bellows type telescopic straw.

In accordance with the above-mentioned problems, the present invention can easily and reliably identify at a low cost as much as possible the fact that the bellows-type telescopic straw is configured by inserting a pair of inner and outer straws having two different diameters. As described above, the identification line is arranged on one of the straws on the inside and outside so that the consumer can recognize that the other straw is inserted into the one straw with the end position of the identification line as a boundary. Thus, the above-mentioned outer diameter straw can be held and prevented from being stretched to prevent the trouble of the straw. an insertion tip of the small diameter straw inside a outer large diameter protruding disposed from straw and the outer side of the large diameter straw longitudinally intermediate the straw arranged bellows folded portion with interpolation, the large-diameter Was transparent locations Torrox and by placing the identification line colored longitudinally series to said large diameter straw, and characterized in that as lifting identify small diameter straw inside of different diameters pair as slides lead This is a bellows type expansion / contraction straw.

In addition to the above, the invention according to claim 2 is capable of always recognizing the identification line when holding a straw, and more reliably eliminating the straw trouble caused by oversight of the identification line. As described above, the bellows-type telescopic straw according to claim 1, wherein a plurality of the identification lines are arranged in parallel to the outer circumferential direction of the large-diameter straw .

  The present invention uses these as the gist of the present invention and as means for solving the above problems.

  In the present invention, the term “transparent” for the straw is used to mean a semi-transparent material by measures such as roughening or adding a matting agent.

Since the present invention is configured as described above, the invention described in claim 1 is as low as possible that the bellows-type telescopic straw is configured by inserting a pair of inner and outer straws having two different diameters. The identification line is arranged on the outer large-diameter straw so that it can be identified easily and at a glance, depending on the cost, and the inner diameter of the outer large-diameter straw is set with the end position of the identification line as a boundary. In order to prevent the trouble that the customer can recognize that the straw is inserted, the straw that is extended by holding the outer large-diameter straw by hand is extended. A bellows-type telescopic straw can be provided.

  In addition to the above, the invention according to claim 2 is capable of always recognizing the identification line when holding a straw, and more reliably eliminating the straw trouble caused by oversight of the identification line. It can be.

It is a front view of a bellows type expansion-contraction straw. It is a front view of the state which extended the bellows type expansion-contraction straw. It is a front view of an inside small diameter straw. It is a front view of an outer diameter straw. It is a front view which shows the state of a straw trouble. It is a perspective view of the pack container which attached the bellows type expansion-contraction straw.

  Hereinafter, the present invention will be described in more detail with reference to the examples of the drawings. For example, A is attached to a pack container filled with a beverage such as juice or milk, and used for drinking. For example, it is a bellows type expansion / contraction straw made of polypropylene resin, and the straw A has a pair of inner and outer straws with different diameters slidably pulled out, and the insertion tip 12 of the inner narrow straw 1 is formed on the outer thick side. The bellows bent portion 23 is disposed so as to protrude from the diameter straw 2 and in the middle in the longitudinal direction of the outer diameter large diameter straw 2, and at this time, the straw A has a transparent ground on the inside and outside of the pair of different diameters. It is possible to discriminate the inner narrow straw 1 for slide drawing out of a pair of different diameters by arranging a series of identification lines 3 which are colored with respect to or colored differently with respect to the colored background. There as was.

  In this example, the bellows type expansion / contraction straw A has an extension length of 10 cm. For example, the outer large diameter straw 2 of the pair of different diameters has a length of 8 cm, an outer diameter of about 0.6 cm, and an inner side. The outer diameter straw 1 has a length of a little less than 10 cm and an outer diameter of about 0.5 cm. The bellows bent portion 23 having a multi-stage, for example, about eight stages, with a length of about 1 cm and an extension length of about 2 cm is disposed.

  The inner small diameter straw 1 has a large diameter preventing portion 11 at the rear end thereof and a distal end insertion portion 12 formed by obliquely cutting the distal end so as to have an acute angle of about 50 °, for example. The outer large-diameter straw 2 has a slightly-width retaining stopper 21 bent radially inward at its rear end, a retaining rib (not shown) projecting inward in the vicinity of the tip, In accordance with the outer shape of the inner narrow straw 1 at the tip, the inner narrow straw 1 is prevented from swinging, and the slide drawer of the inner narrow straw 1 is guided in a straight line and the inner narrow straw 1 is A small-diameter guide 22 that also serves as a stopper for the large-diameter portion 11 is arranged. At this time, before forming the retainer 21 at the rear end of the outer thick straw 2, the inner thin straw 1 is inserted into the outer thick straw 2 so that the inner thick straw 2 is inserted into the inner thick straw 2. The small-diameter straw 1 is slid out to extend the whole, and the tip insertion portion 12 is inserted into the insertion port of the pack container B, and the hermetic seal is broken to suck the beverage filled in the pack container B. It is meant to be used.

  In this example, the bellows type expansion / contraction straw A has a color tone different from that of the inside and outside, for example, the inner thin straw 1 is white and the outer thick straw 2 is transparent. The tip insertion portion 12 of the small diameter straw 1 is equivalent to the reduced length of the bellows bent portion 23 of the outer large diameter straw 2, for example, about 1 cm or less from the front end of the outer large diameter straw 2. Thus, the protruding length of the tip protruding portion 12 is equal to or relatively short with respect to the extended length of the bellows bent portion 23. In this example, It is relatively short.

  At this time, in the present example, the identification line 3 is disposed on the outer large-diameter straw 2 which is a transparent ground in the present example, out of the pair of different diameters. The arrangement of the outer large-diameter straw 2 is arranged in a series including the bellows bent portion 23 in the middle in the longitudinal direction so as to extend over the entire length in the longitudinal direction by, for example, forming two-color molding of the outer large-diameter straw 2. According to the arrangement of the identification line 3, the bellows type expansion / contraction straw A has a two-member structure by inserting a pair of inner and outer straws 1, 2 having different diameters. The consumer can identify the target part at a glance. The identification line 3 has a conspicuous form suitable for identification as a design element, for example, in a color tone such as blue or red, with respect to the transparent ground.

  The width of the identification line 3 is not limited as long as it can be identified. In this example, the width is, for example, 0. A relatively narrow width of about several mm to 2 mm, in this example about 1 mm or less.

  In this example, the identification line 3 is a plurality of strips, for example, two strips arranged in parallel to the outer circumferential direction of the outer thick straw 2. At this time, the identification line 3 of the present example is arranged such that the two strips are arranged at intervals of 1/2 circle on the front and back in the outer circumferential direction, whereby the identification line 3 is placed on the pack container B with a transparent film. Thus, it is possible to make sure that the above-mentioned identification can be surely made possible by always touching the consumer's eyes, including the state of being individually attached and the state of being held by hand to pull out the slide.

  Accordingly, the protrusion of the distal end insertion portion 12 is set to a length of a little less than 1 cm, while the bellows bent portion 23 having a relative length relationship exceeding the extension length is formed on the outer large-diameter straw 2. By providing the both ends of the outer large-diameter straw 2 and carrying out a slide pulling operation, the possibility that the inner small-diameter straw 1 is immersed in the outer large-diameter straw 2 is indicated by the identification line 3, in particular It is possible to prevent the customer's straw trouble as much as possible by preventing it by arranging a plurality of identification lines as much as possible. In addition, since the identification line 3 is arranged by using a two-color molding method when the outer large-diameter straw 2 is extruded, the production cost is prevented as much as possible. The cost can be as low as possible.

  Although the illustrated example is as described above, the identification line is disposed on the inner narrow straw among the pair of different diameters, the identification line is formed by the pair of thin lines, and the identification line is arranged in the outer circumferential direction. When the multiple strips are arranged in parallel with each other, the number of strips and the interval are appropriately set so that the strips are three strips at equal intervals of 1/3 circle in the circumferential direction, and four strips at regular intervals of 1/4 circle. Each specific shape of the inner narrow straw, its insertion tip, the outer thick straw, the bellows bent portion, the ground color of these straws, the identification line, the color tone, etc. The structure, material, dimensions, relationship between these, addition to these, and the like can be in various forms as long as they do not contradict the gist of the invention.
