Description

  The present invention relates to glass bottles, synthetic resin bottles, metal bottles and the like, and more particularly to stackable bottles that can be stacked.

  Stackable bottles have the merits of being able to stack and sell and display multiple bottles that store different contents, the space to be displayed can be three-dimensional, and the design is interesting, for example, disclosed in the following patent document Has been.

In order to obtain stability when stacking bottles, stackable bottles like this are formed by forming a recess in the center of the bottom of the bottle and fitting the top of the bottle (mouth or shoulder) into the recess. Has been done.
For example, when displaying such bottles stacked in a storefront, there is a problem that labels are difficult to arrange in a certain direction and tend to be arranged separately, which reduces the appeal to consumers. In order to arrange the labels in different directions in a certain direction, it is necessary to stack the bottles and then rotate them to position them, which requires labor. In addition, there is a drawback that the direction gradually shifts even if it is correctly positioned once.

In order to solve such a problem, the following Patent Documents 1 and 2 disclose a detent mechanism that prevents the stacked bottles from rotating.
This is because a step such as a polygonal shape or a crescent-shaped protrusion is formed on the shoulder of the bottle, and the step or protrusion is inserted into the recess at the center of the bottom of the bottle, so that the upper bottle is against the lower bottle. This prevents rotation.

The conventional anti-rotation mechanism has a problem in that design restrictions are large because it is indispensable to form a step or a protrusion on the most prominent bottle shoulder.
It is an object of the present invention to eliminate the design step of the bottle shoulder and release design restrictions, and to provide an automatic alignment function as well as a simple detent mechanism.

[Claim 1]
The present invention has a concave portion at the center of the bottom of the bottle, has a bottom arch that has a bow shape that changes in height along the circumferential direction at the outer periphery of the bottom of the bottle, A shoulder portion having a bow-like front shape corresponding to the bottom arcuate portion on a shoulder portion whose diameter is reduced toward the upper mouth portion, and when the bottles are stacked, A stackable bottle characterized in that the bottom arcuate part is placed and positioned on a convex part.

Since the bottom arcuate part is placed on the shoulder arcuate part in a state where the concave and convex portions are fitted, the shoulder arcuate part and the bottom arcuate part are settled at a predetermined position to prevent rotation.
In addition, even if the bottles are stacked at slightly different positions (slightly rotated from the normal position), the bottom arcuate part slides on the slope of the shoulder arcuate part and rotates to the position where the unevenness is in place. Is rotated so as to be in a predetermined position, so that alignment is performed almost automatically.

[Claim 2]
Moreover, the present invention is the stackable bottle according to claim 1, wherein a difference in height in the circumferential direction between the bottom arcuate portion and the shoulder arcuate portion is 0.3 to 3 mm.

  If the height difference Δh in the circumferential direction between the bottom arcuate part and the shoulder arcuate part is less than 0.3 mm, the bottle detent function and the automatic alignment function are insufficient. The difference in height in the circumferential direction between the bottom arcuate part and the shoulder arcuate part is 0.3 to 3 mm, and if it is 3 mm or less, it is hardly noticeable that the front shape of the bottom part and the shoulder part is an arcuate shape. The impact is reduced.

[Claim 3]
Further, the present invention has a concave portion in the central portion of the outer surface of the bottom of the bottle, and has a bottom wavy portion formed in a corrugated shape whose height changes along the circumferential direction on the outer periphery of the bottom of the bottle. There is a shoulder corrugated portion having a corrugated shape corresponding to the bottom corrugated portion on the shoulder that is reduced in diameter toward the upper mouth portion, and when the bottles are stacked, the bottom corrugated portion is placed on the shoulder corrugated portion. Is a stackable bottle characterized by being placed and positioned.

  Even if the shape of the bottle bottom and shoulder is formed in a wave shape, the same effect as in the case of the first aspect can be obtained. The bottom corrugated portion and the shoulder corrugated portion may be on the entire circumference of the bottom portion or the shoulder portion, or may be a part thereof.

[Claim 4]
Further, the present invention provides the stackable bottle according to claim 3, wherein a difference in height in the circumferential direction between the bottom corrugated portion and the shoulder corrugated portion is 0.3 to 3 mm.

  If the difference in height in the circumferential direction between the bottom corrugated portion and the shoulder corrugated portion is less than 0.3 mm, the bottle detent function and the automatic alignment function are insufficient. The difference in height in the circumferential direction between the bottom corrugated portion and the shoulder corrugated portion is sufficient to be 0.3 to 3 mm, and if it is 3 mm or less, it is hardly noticeable that the front shape of the bottom portion and the shoulder portion is corrugated, which has an influence on the design. Get smaller.

  Since the stackable bottle of the present invention does not require a step or a protrusion on the shoulder, there is no such design restriction, and the degree of freedom in design is greatly increased. The anti-rotation mechanism in the present invention is not limited to a simple anti-rotation mechanism, and even if the bottles are stacked in a state slightly rotated from the normal position, the bottom arch is formed on the slope of the shoulder arch (or the shoulder undulation). Since the shape portion (or the bottom wave shape portion) slides and rotates so that the upper bottle is in a predetermined position, alignment is performed almost automatically.

  The bottle 1 is made of glass and has a planar shape such as a rounded square. As shown in FIGS. 3 and 4, a concave portion 33 having a bottom surface greatly recessed inward is formed in the center portion of the bottom portion 3, and the height changes along the circumferential direction on the outer peripheral portion, and the front shape is a bow. Four bottom arcuate portions 31 are formed. In FIG. 3, a portion indicated by shading on the outer peripheral portion is a bottom arcuate portion 31. In the case of the present embodiment, the bottom arcuate portion 31 is a convex arcuate shape when viewed from the bottom at the center, but may be a concave arcuate shape when viewed from the opposite side. A knurling (small protrusion) 34 is formed on the entire outer periphery of the bottom 3. In FIG. 3, the knurling is schematically shown by three broken lines and is omitted in other drawings.

The peripheral wall 2 of the bottle 1 is substantially vertical at the body portion, and the upper portion is a tapered shoulder portion 4 whose diameter is reduced toward the mouth portion 5 at the upper end. A shoulder arch portion 41 having an arcuate front shape corresponding to the bottom arch portion 31 is formed on the shoulder portion 4. In FIG. 2, a portion indicated by shading is a shoulder arch portion 41. The shoulder arcuate portion 41 is a concave arcuate shape when viewed from above, and its shape is substantially the same as that of the bottom arcuate portion 31 (unless manufacturing errors are taken into consideration), and therefore, as shown in FIGS. When the bottles 1 are stacked, the bottom arcuate portion 31 is placed on the shoulder arcuate portion 41 and overlaps. In this embodiment, since the knurling 34 is formed on the bottom surface, the bottom arcuate portion 31 is placed on the shoulder arcuate portion 41 via the knurling. 41 and bottom arcuate part 31 are in direct contact.
A screw thread is formed on the outer periphery of the mouth of the upper end of the bottle 1 and the cap 6 is screwed, but the screw thread is omitted in the drawing.

  As shown in FIGS. 5 and 6, when the bottles 1 are stacked in a plurality of stages, the upper part of the bottle 1 (the part above the shoulder arch part 41) enters the recessed part 33 at the bottom, and A bottom arcuate portion 31 is placed on top and overlaps. At this time, since the shoulder arch-like portion 41 and the bottom arch-like portion 31 are in an uneven fit state, the rotation of the bottle is prevented (rotation prevention function).

  Further, even when the bottles are stacked in a state slightly rotated from the normal position, the bottom arch portion slides on the slope of the shoulder arch portion 41 so that the shoulder arch portion 41 and the bottom arch portion 31 overlap. Since the upper bottle rotates to a predetermined position, alignment is performed almost automatically (automatic alignment function).

  7 to 10 relate to the stackable bottle 1a of the embodiment. FIG. 7 is a front view, FIG. 8 is a plan view, FIG. 9 is a bottom view, and FIG.

  The bottle 1a is a glass bottle, and the planar shape is a round bottle. As shown in FIG. 9, a concave portion 33 is formed at the center of the bottom 3, and the outer peripheral portion is a bottom corrugated portion 32 whose height changes in a wave shape along the circumferential direction. In FIG. 9, a portion indicated by hatching on the outer peripheral portion is a bottom wave-like portion 32, and a sine wave shape wave is formed over the entire circumference as viewed from the front. The thin shaded part (reference numeral 32a) is a concave part when viewed from below, and the dark shaded part (reference numeral 32b) is a convex part when viewed from below. A knurling (small protrusion) 34 is formed on the entire outer periphery of the bottom 3. In FIG. 9, the knurling is schematically shown by three broken lines, and is omitted in other drawings.

The peripheral wall 2 of the bottle 1a is substantially vertical at the body portion, and the upper portion is a tapered shoulder portion 4 that is reduced in diameter toward the mouth portion 5 at the upper end. In the shoulder portion 4, a corrugated shoulder corrugated portion 42 corresponding to the bottom corrugated portion 32 is formed over the entire circumference. In FIG. 8, the shaded portion is a shoulder-like portion 42, the shape of which is substantially the same sine wave shape as the bottom wave upper portion 32, and the thin shaded portion (reference numeral 42a) is convex when viewed from above. The portion and the dark shaded portion (reference numeral 32b) are concave portions as viewed from above.
A screw thread is formed on the outer periphery of the mouth of the upper end of the bottle 1 and the cap 6 is screwed, but the screw thread is omitted in the drawing.

  As shown in FIG. 10, when the bottles 1 a are stacked in a plurality of stages, the upper part of the bottle 1 a (the part above the shoulder wave-shaped part 42) enters the bottom recessed part 33, and the bottom wave-like shape is formed on the shoulder wave-shaped part 42. The part 32 is placed and overlapped. At this time, since the shoulder corrugated portion 42 and the bottom corrugated portion 32 are in an uneven state, rotation of the bottle is prevented (rotation preventing function).

  Further, even if the bottles are stacked slightly rotated from the normal position, the upper bottle is so formed that the bottom corrugated portion 32 slides on the slope of the shoulder corrugated portion 42 and the shoulder corrugated portion 42 and the bottom corrugated portion 32 overlap. Is rotated to a predetermined position, so that alignment is performed almost automatically (automatic alignment function).
