Like Fig. 1 and shown in Figure 2, doleiform container 10 mainly by the roughly rectangular main part 12 of oral area 11, the transversal surface of filling liquid such as beverage, link oral area 11 and main part 12 shoulders 13, constitute in the bottom 14 of the opposition side sealing main part 12 of oral area 11.And, though can bottle cap be installed on the oral area 11,, omitted diagram to bottle cap for the purpose of simplifying.

Fig. 3 is the upward view of doleiform container shown in Figure 1.In the bottom 14, around the line of centers C0 of doleiform container 10, be formed with circular pit 18.And a plurality of base channel 14a are with the radial outer peripheral face (please with reference to Fig. 2) that extends to doleiform container 10 from circular pit 18.These circular pit 18 are brought into play the effect of the bottom 14 of strengthening doleiform container 10 with base channel 14a.

Like Fig. 1 and shown in Figure 2,, be formed with all upwardly extending waist 15 at main part 12 in the longitudinal center position of main part 12.As shown in Figure 2; Waist 15 is the flute profile attitude of wider width, by constituting from the last lateral incline 15a of main part upper section 40 extensions, the following lateral incline 15b that part 45 is extended from the main part below, the groove bottom 15c that links above-mentioned lateral incline 15a of going up and following lateral incline 15b.Through such waist 15 main part 12 is divided into main part upper section 40 and main part below part 45.

Fig. 4 is the sectional elevation of observing along the B-B line of doleiform container shown in Figure 2.As shown in Figure 4, comprise that the transverse shape in zone of groove bottom 15c of waist 15 is also roughly rectangular.

Fig. 5 is the partial enlarged drawing of the doleiform container that relates to of this embodiment.Can know that from Fig. 5 the above-mentioned lateral incline 15a of going up extends respectively with upper limb and the lower edge of following lateral incline 15b in the horizontal direction.In addition, the groove bottom 15c of waist 15 is perpendicular to the bottom surface of doleiform container 10.

Waist 15 single-pieces highly are 41.9mm vertically, and only vertical height of the groove bottom 15c of waist 15 is 7mm.Therefore, can people's thumb, relative with thumb 4 for example be pointed the position between forefinger, middle finger, the third finger, little finger of toe and these finger roots and the palm portion that is associated is closely attached on waist 15.In addition, as shown in the figure, the following lateral incline 15b of waist 15 compares quite big with last lateral incline 15a, and in addition, following lateral incline 15b is made up of convex curved surface towards the outside.

And, can know from Fig. 5, in the face side of doleiform container 10, be formed with recess 20 in waist 15 zones.Can know from Fig. 4,, also relatively be formed with recess 20 each other in the rear side of doleiform container 10.And, also can make recess 20 be adjacent to waist 15 and above or below being formed on.

In Fig. 5, the part of the top and bottom of recess 20 respectively doleiform container 10 vertically on cross groove bottom 15c and lateral incline 15a and following lateral incline 15b on extending to.In addition, the edge portion of recess 20 by be formed on rising wood 21 on the lateral incline 15a, be formed on down lower edge 23 on the lateral incline 15b, the middle edge portion 22 that on the whole span of groove bottom 15c, vertically forms constitutes.

And as shown in Figure 5, recess 20 has smooth recess bottom surface 26.Recess bottom surface 26 by the oblong of horizontal expansion, have and the isosceles trapezoid of falling of the upper base that the long limit of this rectangular downside is common constitutes.Can know that from Fig. 5 the isosceles trapezoid of recess bottom surface 26 partly gets into groove bottom 15c zone.And recess bottom surface 26 also can be to be different from shape shown in Figure 5, but preferably can fully accommodate the size in the 1st joint of finger.

In Fig. 5, the lower edge of recess 20 23 bends to convex towards the below.And, can know that from Fig. 5 lower edge 23 is compared quite big with rising wood 21, its result, the radius of curvature of lower edge 23 is compared quite little with the radius of curvature of rising wood 21.Because lower edge 23 is above-mentioned shape, so finger easily is contained in the recess 20 through lower edge 23 from the outside of main part 12.

Can know that from Fig. 4 and Fig. 5 the 1st and the 2nd C word shape curved

surface

33,34 through adjoining each other is attached at recess 20 lower edge 23 on the recess bottom surface 26.The both ends of the 1st the C word shape curved surface 33 that extends from lower edge 23 are attached on the dip plane 32 edge portions 22 and recess bottom surfaces 26 in the middle of dip plane 32 links.The 2nd the C word shape curved surface 34 that is adjacent to recess bottom surface 26 is not attached on the dip plane 32.In addition, the 2nd C word shape curved surface 34 has 2 reinforced

ribs

35,36 that on horizontal part, extend.Can strengthen the recess 20 of doleiform container 10 through above-mentioned

reinforced rib

35,36 in the horizontal.In addition, above-mentioned

reinforced rib

35,36 is also brought into play for the skidproof effect of people's finger.

Through top 31 recess 20 rising woods 21 are attached on the recess bottom surface 26.In Fig. 5, the rising wood 21 of recess 20 bends to convex with top 31 towards the top.Rising wood 21, above 31 be roughly parallel to waist 15 and under the situation of extending, when picking up doleiform container 10, people's finger might snap in rising wood 21 or top 31.To this, rising wood 21 with above 31 towards above bend among the present invention of convex, people's finger can not snap in rising wood 21 and top 31.And, can know that from Fig. 5 the lateral center portion of recess 20 bends to convex towards the top.Though the recess 20 among Fig. 5 be depicted as with after circular-arc as chord length of the transverse distance D3 of the recess stated, if the lateral center portion of doleiform container 10 is in the top, then the position except this central portion also can comprise the linearly position of shape.

Fig. 6 is the longitudinal section of observing along the A-A line of doleiform container shown in Figure 2, and Fig. 7 is the longitudinal section of the recess among Fig. 6.Especially can know from Fig. 7, near recess bottom surface 26, above 31 inside bend towards doleiform container 10 become convex.Above 31 can form by 1 curved surface at least, perhaps, also can form by a plurality of tabular surfaces.

Because recess 20 becomes above-mentioned shape and size, if therefore doleiform container 10 is held and picked up to people's handgrip, the finger top that then is housed in recess 20 hang over top 31 and recess bottom surface 26 between sweep.Thereby, even at doleiform container 10 because of being filled with under the heavier situation of beverage, the finger top can easily not skid off from recess 20 yet.Therefore, in the present invention, can pick up doleiform container 10 simply.

In addition, because a pair of recess 20 forms each other relatively, therefore can be for example in thumb and the middle finger insertion recess 20 separately with different fingers.Thereby, in this embodiment, can be easily and positively control doleiform container 10.

And in this embodiment, the degree of depth of recess 20 (being equivalent to the distance perpendicular to recess bottom surface 26 between waist 15 and the recess bottom surface 26) is deep.The depth D separately 1 of recess 20 is 5mm to 7mm, preferred 6mm.If depth D 1 less than 5mm, then point the top become be difficult to hang over top 31 and recess bottom surface 26 between sweep.On the other hand, if depth D 1 greater than 7mm, then point the top become be difficult to arrive top 31 and recess bottom surface 26 between sweep.In addition, the transverse distance D3 of recess 20 is 54mm to 62mm, preferred 58mm.

Because recess 20 becomes above-mentioned size, therefore when controlling doleiform container 10, at least 1 the 1st joint in the middle of people's thumb or the middle finger fully is contained in recess 20.And if the recess bottom surface 26 of pushing recess 20 respectively through people's thumb and middle finger, then at least 1 central axis in the middle of thumb or the middle finger is in recess 20 with main part 12 outsides and compares the position near the inboard.Its result can make thumb or middle finger positively hang over top 31 of recess 20.

And if will comprise distance between the minor face of transversal surface in zone of waist 15 groove bottom 15c as D2, then D2 is 67mm to 74mm, preferred 71mm.Sensation was picked up these article easily when the people generally controlled thing under the state of thumb that opens one's hand naturally and finger in addition.Therefore,, apply bigger power, therefore under the situation of the bottle cap that takes off doleiform container 10, the liquid in the doleiform container 10 is flowed out from oral area 11 through the finger top if distance B 2, feels then that narrow width is difficult to pick up less than 67mm.On the other hand, if distance B 2, feels then that wide being difficult to of width pick up greater than 74mm, the liquid in the doleiform container 10 are flowed out from oral area 11.And, for the total degree of depth (D1+D1) of 2 recesses of distance B 2 than being about 0.16, preferably should be than being 0.13 to 0.20.In the case, can more suitably control doleiform container 10.

But, can know that with reference to Fig. 4 the transversal surface of the main part below part 45 of doleiform container 10 is roughly rectangular, its 4 bights 19 are circular arc, and the transversal surface of main part upper section 40 is also identical.In the present invention, comprise that the transversal surface in zone of waist 15 groove bottom 15c is roughly rectangular similarly, its 4 bights 16 also are circular arc.

Fig. 8 is the lateral plan of the doleiform container of embodiment shown in Figure 1.In Fig. 8, when the people wanted to control doleiform container 10, two of people pointed for example thumb and middle finger insert waist 15 from the direction of the paper that runs through Fig. 8 mutual relative part.In this embodiment, the longitudinal size of waist 15 is 41.9mm, and is bigger, and waist 15 forms at the peripheral part of main part 12 on the whole in addition, and as aforesaid with reference to Fig. 5, waist 15 is the structure that comprises lateral incline 15a and following lateral incline 15b.Thereby last lateral incline 15a and following lateral incline 15b bring into play so-called directional tagging, 2 fingers of said people are directed to the periphery of groove bottom 15c.

In addition, in Fig. 4, show 2 long paracentral line A1 through main part 12 transversal surfaces.This line A1 is common line with the line that interconnects 2 relative recess 20 centers.2 some C1, C2 disposing on the online A1 are positioned at the circumferential extended line of groove bottom 15c and the intersection point of line A1.As shown in Figure 4, extend in addition from the part of extended line and the groove bottom 15c of 1 some C1 through groove bottom 15c that the circumferential distance D4 of 1 some C2 is 140mm to 165mm, preferred 150mm to 156mm.Be shorter than under the situation of 140mm at this circumferential distance D4, when the long people of finger controlled doleiform container 10, the finger top surpassed recess 20.In addition, be longer than at circumferential distance D4 under the situation of 165mm, when the short people of finger controlled doleiform container 10, the finger top can't arrive the curve of recess 20 top 31.Relative therewith, under the situation in circumferential distance D4 is in the scope of 140mm to 165mm,, also can both easily control doleiform container 10 even the long people of finger still points short people.

And if from thumb and forefinger side observer's hand, then people's hand roughly is the C word shape usually.The mode that does not need exceedingly to spread one's fingers with people's hand determines the size of distance B 2.Because doleiform container 10 waists 15 are bigger at the radius of curvature in 4 bights 16 at groove bottom 15c place, so doleiform container 10 suitably contacts the roughly people's of C word shape hand.Thereby, when controlling doleiform container 10, do not need exceedingly to open people's finger.And the radius of curvature of waist 15 in 4 bights 16 at groove bottom 15c place is 24mm to 34mm, preferred 28mm to 30mm.

If 2 of people fingers insert waists 15, then for example point the position between the thumb and middle finger, these finger roots and the palm portion that is associated just is suitable for waist 15 and last lateral incline 15a for the people's 2.Thus, people's finger top can arrive the curve of recess 20 top 31.Thereby if under this state, lift people's hand, then doleiform container 10 is for example pointed the position between thumb and middle finger, these finger roots by 2 of people and the palmar hand branch that is associated supports.Therefore, when picking up doleiform container 10, need not control doleiform container 10 with big power.So, can easily pick up doleiform container 10.

Therefore in addition, owing to need not apply big power with the top of finger, even under the situation that for example bottle cap of doleiform container 10 is removed, the liquid in the doleiform container 10 also can not flow out from oral area 11.Therefore, can stably pick up and carry doleiform container 10.

At this, if with reference to Fig. 1, Fig. 2 and Fig. 6, then be formed with a plurality of grooves 41 of circumferential extension at the main part upper section 40 of main part 12, part 45 is formed with a plurality of grooves 46 of circumferential extension below main part.When doleiform container 10 was applied longitudinal force, these

groove

41,46 performances made the main part 12 of doleiform container 10 that the effect of elastic deformation take place in the vertical.

Owing to paste Commercial goods labels (not shown) at main part upper section 40 usually; Therefore in order to see Commercial goods labels (not shown) well; In the groove 41 of main part upper section 40, be provided with under the situation of waling etc., just make the main part below part 45 of main part 12 that elastic deformations take place.

In addition, as shown in Figure 6, between shoulder 13 and main part 12, be formed with circular-arc regional X1, below groove that is formed on part 45 below the main part 46 and the main part between the part 45, be formed with circular-arc regional X3 similarly.And, in Fig. 6, though below main part the regional X3 of representative and illustrate and be positioned at the 2nd groove 46 from top to bottom in the part 45, other grooves 46 below main part in the part 45 are also identical.And, as can knowing with reference to Fig. 5 once more, also be formed with circular-arc regional X2 between the part 45 below the following lateral incline 15b of waist 15 and the main part.

Can know from Fig. 6, in regional X1,, compare littler with the radius of curvature of shoulder 13 self though it is bigger to observe the radius of curvature R 1 of doleiform container 10 from the side.Equally, can know from Fig. 2, also bigger from the radius of curvature R 1 ' of top view doleiform container 10 in regional X1, but compare littler with the radius of curvature of shoulder 13.And radius of curvature R 1 is following, compares greatlyyer with the radius of curvature R 3 among the regional X3, compares littler with the radius of curvature R 2 among the regional X2.And, can know that with Fig. 6 the radius of curvature R 2 in regional X2 is greater than the radius of curvature R in regional X3 3 like comparison diagram 5.In addition, the radius of curvature R 1 of observing from the side is R10 to R28, preferred R16 to R20.From the radius of curvature R 1 ' of top view is R10 to R26, preferred R14 to R18.Under these radius of curvature R 1, the situation of R1 ' greater than aforesaid value, when doleiform container 10 was applied longitudinal force, plastic deformation took place in the shoulder 13 of doleiform container 10 easily.

As previously mentioned, when carrying, doleiform container 10 is put into corrugated sheet carton (not shown), and a plurality of corrugated sheet cartons are piled up in order.At this moment, apply sizable longitudinal force on each doleiform container 10.

In this embodiment, radius of curvature R 1, R1 ' be greater than radius of curvature R 2, R3, but compare quite for a short time with the radius of curvature of shoulder 13 self, therefore that is to say the state that on the axis direction of doleiform container 10, erects near shoulder 13.That is, in this embodiment, because radius of curvature R 1, R1 ' be less than the radius of curvature of shoulder 13, therefore the angle for the shoulder 13 of horizontal surface becomes big.Thereby even doleiform container 10 is being applied under the situation of sizable longitudinal force, the shoulder 13 and the waist 15 of doleiform container 10 also deform hardly, and the power that major part applies is delivered to main part below part 45 as the crow flies.Therefore, in this embodiment, if the longitudinal force of applying, then sedimentation takes place in the part approximate equality ground that is positioned at waist 15 tops of doleiform container 10, the main part below part 45 main elastic deformations that take place.That is, in this embodiment, even doleiform container 10 is being applied under the situation of longitudinal force, shoulder 13 and waist 15 can in an inclined direction not bend yet.Thereby, can prevent that these from destroying because of plastic deformation.

And as especially waiting and can know from Fig. 1, the shoulder 13 of doleiform container 10 is level and smooth on its circumferential single-piece span, is not formed with protrusion etc.Thereby, even doleiform container 10 is being applied under the situation of longitudinal force, can be in such protrusion concentrated stress yet, thereby, there is not such protrusion generation plastic deformation yet.Therefore, in this embodiment, can prevent that the shoulder 13 of doleiform container 10 from plastic deformation taking place.

And in this embodiment, though the doleiform container 10 that is formed by synthetic resin is illustrated, doleiform container 10 also can be formed by other materials, is for example formed by glass.
