( Reference Example 1)
Hereinafter, reference examples will be described first with reference to the drawings. FIG. 1 is a front cross-sectional view illustrating a beverage bottle equipped with a beverage bottle opening attachment according to a reference example . 2 is a perspective view showing a first example of an opening attachment for a beverage bottle according to a reference example , FIG. 3A is a plan view thereof, FIG. 3B is a front view thereof, and FIG. 4 is a cross-sectional view taken along line AA in FIG. 5 is an enlarged cross-sectional view of a part of FIG. A beverage bottle opening attachment (hereinafter also simply referred to as an attachment) 10 shown in FIG. 1 is detachably attached to an opening cylindrical portion N formed as an opening in an upper portion of a plastic bottle B (beverage bottle). Specifically, the attachment 10 includes a female threaded cylindrical portion 1, a main body portion 3, and an opening forming cylindrical portion 4.

  As shown in FIGS. 2 to 4, the internal thread of the female threaded cylindrical part 1 is internally threaded with a male thread BS (see FIG. 1) formed on the outer peripheral surface of the open cylindrical part N of the plastic bottle B. Part 2 is formed. The main body 3 has an outer peripheral surface located on the inner side of the open cylindrical portion N in a state where the female screw portion 2 of the female threaded cylindrical portion 1 is screwed into the male screw portion BS of the open cylindrical portion N, and the female threaded cylindrical portion 1. From the inside to the inside of the plastic bottle B, it extends concentrically and integrally with the internally threaded cylindrical portion 1 (see FIG. 1). The main body 3 prevents water (liquid) from entering between the inside and the outside while preventing the passage of a solid (for example, tea TL) having a certain size or more (see FIG. 7). The opening forming cylindrical portion 4 projects from the internally threaded cylindrical portion 1 concentrically and integrally with the cylindrical portion 1 opposite to the main body portion 3. On the outer peripheral surface of the opening forming cylindrical portion 4, a male screw portion 5 that is screwed with a female screw portion CS (see FIG. 1) formed on the inner peripheral surface of the bottle cap C of the plastic bottle B is formed.

  The original form of the plastic bottle B is such that a female screw portion CS formed on the inner peripheral surface of the bottle cap C is screwed into a male screw portion BS formed on the outer peripheral surface of the opening cylindrical portion N (not shown). On the other hand, in the attachment form using the attachment 10, the female screw part 2 of the attachment 10 is screwed to the male screw part BS of the plastic bottle B, and the female screw part CS of the bottle cap C is screwed to the male screw part 5 of the attachment 10 ( (See FIG. 1). Thus, the sharing efficiency of the bottle cap C increases the utilization efficiency of the original form and the attachment form in the plastic bottle B. Of course, you may use the cap only for an attachment form.

The part is configured as a mesh part formed of a mesh (for example, a wire mesh). The mesh portion 32 has a size (for example, 0.5 mm or less) that prevents a solid (for example, tea husk TL; see FIG. 7) from passing through while allowing water (liquid) to enter between the inside and the outside. ).

  A female screw portion 311 (first screw portion) is formed on the inner peripheral surface of the lower end portion of the porous portion 31, and a male screw portion 321 (second screw portion) is formed on the outer peripheral surface of the upper end portion of the mesh portion 32, respectively. 32 is detachably screw-coupled by screwing both screw portions 311 and 321 together. In this screw coupling portion, the maximum outer diameter of the porous portion 31 and the maximum outer diameter of the mesh portion 32 are formed to be the same diameter (level). The male screw portion 321 is a cylindrical body made of synthetic resin, for example, and also serves as a holding portion for the upper end edge of the mesh portion 32.

The unit 34 is configured. The mesh portion 34 has a size (for example, 0.5 mm or less, for example) that prevents a solid (for example, tea husk TL; see FIG. 7) from passing through while allowing water (liquid) to enter between the inside and the outside. ).

( Reference Example 4)
FIG. 30 is a front sectional view showing a fourth example of the beverage bottle opening attachment according to the reference example . The main body 3 of the beverage bottle opening attachment (hereinafter also simply referred to as attachment) 40 shown in FIG. 30 is the upper end of the female threaded cylindrical portion 1 (corresponding to the main body opening 3a of FIG. 4 ( Reference Example 1)). A plurality of through holes 43a are formed in the upper wall portion 43 that is closed in a planar shape. These through-holes 43a have a size (for example, a diameter 1 to 1) that prevents the passage of solid (for example, tea husk TL; see FIG. 32) having a certain size or larger while allowing water (liquid) to enter between the inside and the outside. 2 mm).

After a predetermined time (for example, 10 to 30 minutes), when the female screw part 2 of the attachment 40 is screwed into the male screw part BS of the plastic bottle B and the plastic bottle B is tilted, the tea (extracted liquid) in the plastic bottle B penetrates. It flows out of the opening forming cylindrical portion 4 through the hole 43a. However, the tea husk TL (residue) in the plastic bottle B is captured by the through-hole 43a and is prevented from flowing out (see FIG. 32). Therefore, the tea extracted from the tea leaves T is drunk from the opening forming cylindrical portion 4 of the attachment 40, and the tea husk TL remains in the plastic bottle B and does not flow out. In addition, when the input tea leaves T are extracted in a short time in a floating state, the taste and aroma of the extract (tea) are good.

( Example )
FIG. 33 is a front half sectional view showing an embodiment of the beverage bottle opening attachment according to the present invention, FIG. 34 is a DD sectional enlarged view thereof, and FIG. 35 is an enlarged sectional view showing an essential part of FIG. . The same reference numerals as in FIGS. 1 to 32 are attached to the same members or parts as those in the preceding reference drawings in FIGS. 33 to 37, and the description based on those drawings will be diverted, and duplicate descriptions will be omitted. To do. The body part 3 of the beverage bottle opening attachment (hereinafter also simply referred to as attachment) 50 shown in FIG. 33 has a cylindrical (for example, cylindrical) peripheral wall portion and a distal end that closes in a dome shape (for example, a hemispherical shape) at its lower end. The (lower end) part is integrally molded, and is configured as a porous part 53 in which a large number of through holes 53a and 53b are formed in the peripheral wall part and the tip part, respectively.

As shown in FIG. 34, the peripheral wall through-holes 53a are arranged in a certain direction (in the drawing, for example, four) within a quarter circumference (90 °) when viewed per row in the peripheral wall portion of the porous portion 53. (Inclination 45 ° direction) is formed in parallel, and a plurality of rows (for example, 30 rows) are arranged in the longitudinal direction as a set. On the other hand, the tip through-holes 53b are arranged in a large number (for example, 28 in total) in a plurality of rows (for example, three rows) concentrically at the tip of the porous portion 53, and each is formed radially. These through-holes 53a and 53b have a size (for example, a diameter) that prevents passage of a solid (for example, tea husk TL; see FIG. 7) of a certain size or more while allowing water (liquid) to enter between the inside and the outside. 1-2 mm). In addition, since the porous part 53 does not have the filtration part 312 of FIG. 5 ( reference example 1), the whole inside becomes an accommodation space.

  As shown in FIG. 35, the internally threaded cylindrical portion 1 and the opening forming cylindrical portion 4 are integrally formed of a synthetic resin material. The porous portion 53 (main body portion 3) made of a synthetic resin material is detachable (separable) by friction fitting of the engaging portions 54 and 6 with respect to the integrally formed cylindrical portion 1 with an internal thread and the opening forming cylindrical portion 4. In such a form, they are integrally formed.

  Specifically, one of the inner peripheral surface of the lower end portion of the opening forming cylindrical portion 4 and the outer peripheral surface of the upper end portion of the porous portion 53 (for example, the inner peripheral surface on the opening forming cylindrical portion 4 side) An engagement recess 54 (engagement portion) that fits the engagement projection 6 is formed on the other (for example, the outer peripheral surface on the porous portion 53 side) over the entire circumference. In addition, on the upper side (front side in the insertion direction) of the engagement recess 54, the diameter of the engagement recess 54 is increased toward the lower side in order to guide the engagement projection 6 and fit the engagement recess 54. An enlarged diameter portion 55 connected to the engagement recess 54 with a slightly larger diameter is formed over the entire circumference. Further, in order to seat the engaging convex portion 6 in the fitted state with the engaging concave portion 54 below the engaging concave portion 54 (on the rear side in the insertion direction), from the engaging concave portion 54 and the enlarged diameter portion 55. Also, a large-diameter seating portion 56 is formed to protrude over the entire circumference.

  When the porous portion 53 (main body portion 3) is inserted from the axial direction (upward) inside the opening forming cylindrical portion 4, the enlarged diameter portion 55 of the porous portion 53 rides on the engaging convex portion 6 of the opening forming cylindrical portion 4. Then, the opening forming cylindrical portion 4 elastically deforms the enlarged diameter portion 55 (porous portion 53) inward in the radial direction. Further, when the porous portion 53 is inserted and the enlarged-diameter portion 55 gets over the engaging convex portion 6, the engaging concave portion 54 (porous portion 53) is elastically restored and fits into the engaging convex portion 6 and fixed in an interference fit state. At the same time, the engaging convex portion 6 is seated on the seating portion 56, whereby the porous portion 53 is integrated with the opening forming cylindrical portion 4. Further, when the porous portion 53 is pulled out in the direction opposite to the insertion direction (downward), the enlarged diameter portion 55 is elastically deformed and elastically restored, and the engagement convex portion 6 is overcome in the opposite direction to the above. Since the fitting between the part 6 and the engaging recess 54 is released and the porous part 53 is separated from the opening forming cylindrical part 4 (the female threaded cylindrical part 1), it can be stored and managed separately.

In this embodiment,
(1) Even if the engaging convex portion 6 and the engaging concave portion 54 are not provided on the entire circumference, a plurality of protrusions and depressions are formed at predetermined angular intervals (for example, a total of four at 90 ° intervals) in the circumferential direction. Also good.
(2) The porous portion 53 (main body portion 3) is detachable (separable) by screw fitting instead of friction fitting with respect to the integrally formed female threaded cylindrical portion 1 and the opening forming cylindrical portion 4. And may be integrally formed.

  The usage mode of the attachment 50 configured as described above will be described with reference to FIGS.

  The tea leaves T (food for extraction) are put into the porous part 53 inserted and integrated into the opening forming cylindrical part 4 (cylindrical part 1 with female thread), and the female thread part 2 of the attachment 50 is attached to the male thread part BS of the plastic bottle B. And are immersed in water (or hot water) (see FIG. 36). At this time, if the female screw part CS of the bottle cap C is further screwed into the male screw part 5 of the opening forming cylindrical part 4, the plastic bottle B can be carried. When a predetermined time (for example, 10 to 30 minutes) elapses, the screwing of the male screw part BS and the female screw part 2 is released, the attachment 50 (and the bottle cap C) is removed from the plastic bottle B, and the plastic bottle B is tilted. The tea in the bottle B flows out from the open cylindrical portion N (see FIG. 37). Therefore, the tea extracted from the tea leaves T is drunk from the open cylindrical part N of the plastic bottle B.

  Then, the engagement convex portion 6 and the engagement concave portion 54 are disengaged (see FIG. 35), and the opening forming cylindrical portion 4 (cylindrical portion 1 with a female thread) of the attachment 50 removed from the plastic bottle B is used as the porous portion 53 ( By separating the main body portion 3), the tea husk TL (residue) adhering to the inside of the porous portion 53 can be washed away with tap water or removed with a washing brush (see FIG. 37).

As described above, in the attachment 50, the porous portion 53 (main body portion 3) is detachable (separable) from the opening forming cylindrical portion 4 (cylindrical portion 1 with a female thread) by friction fitting (or screw fitting). As a result, the handleability when cleaning the inside of the porous portion 53 is improved, and the porous portion 53 is easily stored and managed. The attachment 50 may be used in a mode in which the tea leaves T (food for extraction) are put into the plastic bottle B, as in the first mode of use shown in Reference Example 1 (see FIGS. 6 and 7). .

(Modification)
The modification of the main-body part 3 in FIG. 33 is shown in FIG. 38, FIG. In the attachment 50 shown in FIG. 38, an annular flange portion 57 is integrally projected and formed at the upper end of the porous portion 53 (main body portion 3) from the main body opening 3a toward the radially outer side (for example, integrally molded). Yes. The flange portion 57 is placed and held on the upper end surface of the open cylindrical portion N when the porous portion 53 is inserted into the plastic bottle B. The flange portion 57 is connected to the upper end surface of the opening cylindrical portion N of the plastic bottle B and the female threaded cylindrical portion 1 of the attachment 50 by screwing the female screw portion 2 of the female screw cylindrical portion 1 and the male screw portion BS of the plastic bottle B. It is clamped and fixed between the lower end surfaces. As described above, the internal threaded cylindrical portion 1 and the opening forming cylindrical portion 4 and the porous portion 53 (main body portion 3) are separately formed in a divided form, but the porous portion 53 is formed by sandwiching the flange portion 57. It is formed integrally with the female threaded cylindrical portion 1 and the opening forming cylindrical portion 4.

In the attachment 50 shown in FIG. 39, an annular flange portion 57 is integrally projected and formed at the upper end of the porous portion 53 (main body portion 3) from the main body opening 3a outward in the radial direction (for example, integrally molded). Further, a cylindrical wall portion 58 rising upward from a midway portion of the flange portion 57 is formed so as to protrude concentrically (for example, integrally formed) with the internally threaded cylindrical portion 1 and the opening forming cylindrical portion 4. This wall 58 is inserted into the inside of the plastic bottle B, and when the female screw 2 of the female threaded cylindrical part 1 and the male screw BS of the plastic bottle B are screwed together, the wall 58 is formed in the opening forming cylindrical part 4. Since it is located on the inner side, it has a function of positioning (centering) the porous portion 53 in the radial direction with respect to the internally threaded cylindrical portion 1 and the opening forming cylindrical portion 4 (and thus the plastic bottle B).

Therefore, in the usage mode of the attachment 50 shown in FIG. 38 or 39, the integration of the porous portion 53 with the internally threaded cylindrical portion 1 and the opening forming cylindrical portion 4 is achieved by sandwiching the flange portion 57 instead of friction fitting. Other than the above, this is the same as the embodiment (see FIGS. 36 and 37). In addition, the attachment 50 shown in FIG. 38 or FIG. 39 throws the tea leaves T (food for extraction) into the plastic bottle B as in the first mode of use shown in Reference Example 1 (see FIGS. 6 and 7). It is the same as that of an Example also about the point which can be used in an aspect.

  As described above, in the attachment 50 shown in FIG. 38 or 39, the porous portion 53 configured in a separate form with respect to the opening forming cylindrical portion 4 (cylindrical portion 1 with a female thread) by sandwiching the flange portion 57. Since the (main body part 3) can be integrated, the handleability when cleaning the inside of the porous part 53 is improved, and the storage and management of the porous part 53 are also facilitated. In addition, in the attachment 50 shown in FIG. 39, the wall portion 58 makes it easy to position the porous portion 53 in the radial direction (centering) with respect to the internally threaded cylindrical portion 1 and the opening forming cylindrical portion 4 (and thus the plastic bottle B). is there.

( Reference Example 5 )
FIG. 40 is a front half sectional view showing a fifth example of the beverage bottle opening attachment according to the reference example . The beverage bottle opening attachment (hereinafter, also simply referred to as attachment) 60 shown in FIG. 40 is formed by replacing the main body 3 shown in FIG. 38 with a cylindrical (for example, cylindrical) peripheral wall porous portion 631 (first divided main body; one The divided main body portion is divided into a dome-shaped (for example, hemispherical) closed end porous portion 632 (second divided main body portion; other divided main body portion) at the lower end thereof, and both porous portions 631 and 632 are concentric. And detachably connected. As in FIG. 38, a large number of peripheral wall through holes 53a are formed in the peripheral wall of the peripheral wall porous portion 631 located at the upper side, and a large number of front end through holes 53b are formed in the lower end porous portion 632 positioned at the lower side. Yes.

  The lower end portion of the peripheral wall porous portion 631 and the upper end portion of the distal end porous portion 632 are on one side (for example, the inner peripheral surface of the lower end portion of the peripheral wall porous portion 631) on the female screw portion 631a (first screw portion) and on the other side (for example, the front end porous portion 632). Male threaded portion 632a (second threaded portion) is formed on the outer peripheral surface of the upper end portion of the outer peripheral portion of the outer peripheral surface of the outer peripheral surface. )

  Note that the lower end portion of the peripheral wall porous portion 631 and the upper end portion of the tip porous portion 632 may be connected by friction fitting instead of screw coupling. In this case, among the lower end portion of the peripheral wall porous portion 631 and the upper end portion of the distal end porous portion 632, a large diameter portion is formed on one side (for example, the peripheral wall porous portion 631 side), and a small diameter portion is formed on the other side. The small diameter part is fitted and fixed in the axial direction. If the small diameter portion is elastically deformed inward in the radial direction and is elastically restored when fitted, both can be fixed in an interference fit (see FIGS. 40 and 20).

  A usage mode of the attachment 60 configured as described above will be described with reference to FIGS. 41 and 42.

  The tea leaves T (food for extraction) are introduced into the main body 3 in which the peripheral wall porous portion 631 and the tip porous portion 632 are connected, and the main body portion 3 is inserted into the plastic bottle B to open the flange portion 57. It is placed and held on the upper end surface of the cylindrical portion N. Next, the female screw part CS of the bottle cap C is screwed into the male screw part BS of the plastic bottle B, and immersed in water (or hot water) (see FIG. 41). At this time, the plastic bottle B can be carried. After a predetermined time (for example, 10 to 30 minutes), when the male screw part BS and the female screw part CS are unscrewed, the main body part 3 is removed from the plastic bottle B, and the plastic bottle B is tilted, the tea in the plastic bottle B Flows out from the open cylindrical portion N (see FIG. 42). Therefore, the tea extracted from the tea leaves T is drunk from the open cylindrical part N of the plastic bottle B.

  Then, the peripheral wall porous portion 631 and the tip porous portion 632 are separated from the main body portion 3 removed from the plastic bottle B by releasing the fitting (screw connection) between the peripheral wall porous portion 631 and the tip porous portion 632 (see FIG. 40). Tea TL (residue) adhering to the inside of 632 can be easily washed away with tap water or removed with a washing brush (see FIG. 42).

  Thus, tea can be extracted more easily using the main body 3 having the flange portion 57, the plastic bottle B, and the bottle cap C. Further, since the peripheral wall porous portion 631 and the tip porous portion 632 can be separated, it is easy to remove the tea husk TL (residue) attached to the inside of the peripheral wall porous portion 631 and the tip porous portion 632. In addition, in the attachment 50 shown in FIG.33 and FIG.39, also when the main-body part 3 is separable into a surrounding wall porous part and a front-end | tip porous part, removal of the tea-shell TL (residue) becomes easy.
