Description
7 7~i The present invention relates to an elon~ated blow-molded thin-wall bottle formed from synthetic resin, and especially to an elongated biaxial stretch blow-molded thin-wall bottle formed from polyethylenetere-phthalate resin.
Recently, a number of tall or elongated blow-molded thin-wall bottles formed from svnthetic resin have been used, particularly for storing liquids.
This is because such bottles themselves are of light weight, simple to mold, have a good appearance, are low in production cost, etc. Because of the molding operation in the molding process called blowing or blow molding, the wall thickness of the side wall of the bottle inevitably becomes thin.
Particularly in the case where the bottles are molded from polyethyleneterephthalate resin, which has content resisting property, chemi-cals resisting property, acid resisting property, mechanical durability, and various other properties, the articles must be subjected to sufficient biaxial stretch molding. For this reason, the thickness of the side wall, to which the greatest biaxial stretch molding is applied, becomes relatively thin.
This gives rise to a problem in that the side wall is then less resistant to internal pressure and to longitudinally applied pressure.
In particular, the pressure against the side wall tends to act mainly on a portion mid-way of the height of the side wall. Thus, in the event that an even pressure is exerted on the entire side wall, it acts mainly on a specific limited portion thereby resulting in inconveniences such as deformation and even damage.
In the past, therefore, the thickness of the entire side wall has been made such that the side wall can withstand the pressure a ~ing thereon 11S7~7~5 in order to compensate for lack of mechanical strength of the side wall portion. As a consequence, the quantity of synthetic resin material used to mold one bottle considerably increases as compared to the theoretical quantity of synthetic resin material required for a bottle to serve as a container, and this is extremely uneconomical.
Further, if the thickness of the side wall is increased as described above, the pressure of the fluid (mainly, pressurized air) required for blow lding increases. Accordingly, it is necessary to increase the pressure resisting value ofa pressurized fluid flow passage system and to increase the ld-fastening strength of the mold as well as the capacity of the compressor.
Furthermore, in the event that polyethyleneterephthalate resin is used, it is necessary that a piece of material as a primary molding article is lded and cooled, after which the pie~e is evenly reheated up to a temperature capable of achieving blow molding for biaxial stretch blow molding. In reheat-ing the piece up to a temperature capable of achieving the biaxial stretch blow molding, however, the whole piece of increased wall thickness must be reheated to a uniform predetermined temperature, and thus, it takes a long period of time for such reheating, which results in a lowering of molding rate.
The increase in thickness of the side wall for the purpose of compensating for lack of mechanical strength thereof as described above gives rise to various inconveniences in respect of economy, equipment, capacity of molding apparatus and molding rate. Thus, the emergence of means to overcome these difficulties has been desired earnestly.
According to the present invention there is provided a longitudinally extending thin-walled bottle formed from synthetic resin and having an annular groove substantially midway along the height of the bottle, wherein the bottom of the groove has a single outwardly curved protrusion which does not project above the depth of the groove.
~, ,7r7~5 In the accompanying drawings:-Figure 1 is a front view showing the external appearance of oneembodiment of the present invention; and Figure 2 is an enlarged longitudinal sectional view of a portion marked by a circle in Figure 1.
As mentioned above, the present invention is directed to an elongated blow-molded thin-wall bottle formed from synthetic resin, and more particularly to an elongated biaxial stretch blow-molded thin-wall bottle formed from polyethyleneterephthalate resin. In a portion mid-way of the height of a fully biaxial-stretched thin-wall side wall 2 of an elongated molded bottle 1, a constricted part 3 arcuately depressed over the entire periphery of said portion is molded in the form of a peripheral groove, and a bottom portion of the constriction 3 is arcuately deformed oppositely to form a peripheral protrusion 4.
When the bottle 1 is filled with liquid, the relatively largely depressed constriction 3 serves to disperse internal pressure acting on the middle portion both upwardly and downwardly so that the internal pressure does not act mainly on the middle portion but more evenly over the whole side wall 2.
For this reason, the internal pressure per unit area of the side wall 2 is somewhat higher than the case wherein the constriction 3 is not molded, but t}le internal pressure per unit area acting on the constriction 3 is of a value much smaller than the case wherein the constriction 3 is not provided.
As a result of the internal pressure acting substantially evenly ~' ~1~7~7t~
on the whole area of the side wall 2 by the provision of the constriction 3, it is not necessary to increase the wall thickness of the whole side wall 2 in order to increase the strength of a limited portion of the side wall 2.
Thus, it is possible to permit the whole of the side wall 2 to have the thin-wall thickness that will withstand the above-mentioned substantially even internal pressure.
The construction of the bottle is such that the constriction 3 molded in an inwardly arcuately depressed manner is capable of easy elastic deformation in response to a force exerted axially on the bottle 1.
When such an axial force is received, constriction 3 readily deforms to absorb and bear the force before deformation detrimental to the side wall 2 occurs. It is a matter of course, however, that the capability for the constriction 3 to bear the force by elastic deformation is limited, and hence, as the force is permitted to be increased gradually to increase the amount of elastic deformation of the constriction 3, the deformation finally concentrates on the bottom of the constriction 3 to buckle and break the bottom of the constriction 3.
AccordinglyJ the peripheral protrusion 4 is molded in the bottom of the constriction 3 in order to increase the buckling strength of the constriction 3.
As is apparent from the entire construction of the constriction 3 and the peripheral protrusion 4, the peripheral protrusion 4 does not particularly take part in a certain degree of elastic deformation of the constriction 3 due to an axially applied force, but as the amount of elastic deformation incTeases, the peripheral protrusion 4 itself elastically deforms in a direction to impede the increase in elastic deformation.
That is, the elastic deformation of the constriction 3 as a whole proceeds to inwardly displace the bottom of the constriction 3, whereas the ~lS7785 deformation of the peripheral protrusion 4 itself proceeds in the direction of its outward protrusion. Consequently, the elastic defo mation of the constriction 3 cannot concentrate on the bottom or the peripheral protrusion 4, and the whole constriction 3 including the peripheral protrusion 4 is substantially evenly deformed.
As described above, since the constriction 3 including the periph-eral protrusion 4 is subjected to uniform elastic deformation as a whole against axially applied force without permitting the elastic deformation to be concentrated on the specific portion, it is possible to exhibit the extremely powerful buckling strength.
The powerful internal pressure acts on the portion of the peri-pheral protrusion 4, by the provision of the peripheral protrusion 4, as compared to the case where the peripheral protrusion 4, is not provided.
However, since most of internal pressures acting on the middle portion of the side wall 2 in which the constriction 3 is provided are dispersed in both upper and lower directions by the inclined side walls of the constric-tion 3, the amount of internal pressure acting thereupon is just a little.
To further increase the buckling strength of the side wall 2 as a whole against axial forc~, it is advantageous to provide a number of small peripheral recesses 5 over substantially the entire height of the side wall 2, as shown in the drawing.
However, these recesses 5 are not at all affected by axially applied force but merely perform their function to a degree that there is a possibility of preventing breakage of the bottle 1 when excessive force is applied.
The reason is that in the sta~e wherein the portion of the recess 5 need be subjected to elastic deformation, it is time for elastic deformation of the constriction 3 as a whole including ~he peripheral protrusion 4 to 11~7'7~
have already reached its limit.
Accordingly, to increase theh~c~ling strength of the peripheral body 2 is a secondary object of the recesses 5, and a primary object thereof is to provide ornamental effects achieved by giving variety to the external appearance of the bottle 1 as a whole.
Since the constriction 3 is molded in a middle portion of the wall 2, it is possible, in handling the bottle 1 by one hand, to put fingers on the constriction 3, whereby the bottle 1 may be handled safely without permitting the bottle to slip.
