(effect)
The airtight container with resealability that present embodiment relates in order to ensure usability again, is shaped container body and lid together with the PET resin.When utilizing the PET resin to form the lid of revolving type in order to ensure resealability,, therefore need carry out chemical modification herein, to the PET resin because of leak tightness is broken inadequately fully easily by injection moulding.Thereby, in order to come compatibility to guarantee leak tightness and prevent to break as prerequisite, make container body, especially its oral area hardening to use general-duty PET resin, make in addition and cover deliquescing.And then make that lid becomes inserted type rather than revolving type.By making the oral area hardening, can prevent to cover deliquescing by making owing to distortion destroys leak tightness, can reduce breaking of lid.Make under the situation of covering deliquescing, be difficult to be made into the lid of revolving type, therefore adopting the lid of inserted type.In order to make the oral area hardening, can consider to strengthen the method for the wall thickness of oral area, but the oral area hardness that can improve by this method is limited herein.Therefore, make container body have as follows structure and suppress the oral area distortion, that is: when stress during, be limited in the body by distortion, thereby suppress the oral area distortion body at body.
Below embodiment will be shown, the present invention is described in detail, but the invention is not restricted to the annotation that these records are done.At first, with reference to Fig. 1～Fig. 7, the airtight container with resealability that present embodiment is related to describes.In addition, same parts, same position are marked with same label.
The signal longitudinal diagram of a mode of the airtight container with resealability that present embodiment relates to has been shown among Fig. 1.Airtight container 100 shown in Figure 1 comprises: container body 1, and it has the oral area 3 of tubular; With lid 2, it forms the tubular of band end face 5, the chimeric next airtight oral area 3 from the outside of oral area 3, and container body 1 is shaped by pet resin and forms, and container body 1 has following structure: when when body 4 effects have stress, be limited to the distortion that suppresses oral area 3 in the body 4 by distortion with body 4, oral area 3 has on drum outer wall along circumferential ring-shaped continuous protuberance 6, lid 2 has on drum outer wall along the ring-shaped continuous recess 7 of circumferential chimeric annular convex 6 usefulness, and, be 1.320～1.340g/cm by density
3The noncrystalline pet resin be shaped and form, wall thickness is more than or equal to 80 μ m and less than 390 μ m.
The content that is filled in the container body 1 mainly is various beverages such as beer, sparkling wine, soda, belly wash, also can be flavoring, cooking oil or food.The airtight container that present embodiment relates to has resealability, promptly has comformability to filling content, requirement just can obtain the characteristic of degree leak tightness as described below: when adding a cover once more, grasping container or be placed under the situation of the inside of bag etc. carrying, act on container when using under the situation that load is arranged, water can not spill at least.Therefore, has the comformability that can be used as the large-rolume container more than 1 liter.
On oral area 3, be provided with circumferential ring-shaped continuous protuberance 6 in the drum outer wall upper edge.In the airtight container with resealability 100 shown in Figure 1, as annular convex 6, show the annular convex 6a that is provided with a front side and this two the situation of annular convex 6b that is located at its below, but annular convex 6 can only be provided with one, perhaps also can be provided with more than three.The number of annular convex 6 is many more, and the power that is adjacent to of lid 2 is high more, so will suitably determine according to desired compressive resistance.In addition, this number is subjected to the restriction of the tube length of oral area 3.
It is 1.320～1.340g/cm that lid 2 uses density
3The noncrystalline pet resin be shaped.Lid 2 has light transmission, thereby also can confirm content by covering 2.As the noncrystalline pet resin, the noncrystalline pet resin that is called as A-PET and is called as PETG is generally arranged, contain the material that hinders crystallization in the PET resin or the material that will hinder crystallization is aggregated to as the part in the structure in the crystalline texture of PET by making, realize noncrystallineization thus.Use this resin to make wall thickness be configured as more than or equal to 80 μ m and less than 390 μ m, be preferably shaped to 150～300 μ m, be imbued with flexibility, can not break and lid that adaptation is good thereby become.Because have the flexibility of appropriateness, so will cover 2 when being installed on the oral area 3 of container body 1 once more, cover 2 distortion in the scope of plastic deformation, thereby obtain resealability when can guarantee leak tightness.When lid 2 wall thickness during,,, in being the situation etc. of soda, content under the pressure condition with higher, breaks sometimes because wall thickness is thinner though also have flexibility less than 80 μ m; In addition, when wall thickness more than or equal to 390 μ m the time, the shortage that becomes flexibility is broken sometimes.In addition, because amount of resin increases, so economy can descend.
Because lid 2 is configured as wall thickness more than or equal to 80 μ m and less than 390 μ m, therefore preferably forms by pressing empty method or vacuum method to be shaped.Can be formed in the above-mentioned wall thickness scope by the lid of pressing empty method or vacuum method to be shaped, and cheap.Fig. 2 represents to use the process of pressing empty method to become female cap 2, and (a) the display plate heating period, (b) empty shaping stage is pressed in expression, (c) the expression ejection phase.For example, prepare thickness for being 1.320～1.340g/cm more than or equal to 80 μ m and less than 390 μ m, density
3The plate 23 of noncrystalline pet resin system, heat (with reference to Fig. 2 (a) by heating plate 21.)。Then, plate 23 is clipped between metal paattern 22 and the heating plate 21, goes out pressurized air 24 from the top blast of heating plate 21, thus to the inside face stripper plate 23 of metal paattern 22 (with reference to Fig. 2 (b).)。Plate 23 be deformed into cover 2 shape after, from metal paattern 22, take out and cover 2 (with reference to Fig. 2 (c).)。Owing to a plurality of lids 2 that can be shaped with a plate 23, therefore will cover 2 cuts and separates (not shown) singly.
Below, the relation between the annular recessed portion 7 of the annular convex 6 of container body 1 and lid 2 is described.As shown in Figure 1, in the elevation profile of container, the shape of annular convex 6 is preferably semi-round protuberance.Perhaps, the shape of annular convex 6 also can be half elliptic.When the surface of annular convex 6 is extended into when square, can't successfully open lid and closing cap sometimes.In order to improve leak tightness, the shape of annular convex 6 is preferably with the shape of annular recessed portion 7 has corresponding relation, and it is chimeric to be convenient to annular recessed portion 7.In airtight container shown in Figure 1 100, annular convex 6a has the shape with the corresponding relation of annular recessed portion 7a, and annular convex 6b has the shape with the corresponding relation of annular recessed portion 7b.Thereby annular convex 6a is entrenched among the annular recessed portion 7a, and annular convex 6b is entrenched among the annular recessed portion 7b.
In the airtight container with resealability of present embodiment, drawing upward and covering 2 end face is more than the 9.8N up to the be opened power of being adjacent to of the lid that sealing is measured to of lid 2, is preferably more than the 20N.Thereby, reduced the unlatching of content, and utilized and to open covering when guaranteeing leak tightness and can easily seal again after the sealing.The degree of depth of the height of annular convex 6 and cooresponding therewith annular recessed portion 7 is big more, the power that is adjacent to of lid is just big more, and the surface of annular convex 6 and annular recessed portion 7 is extended into square more, and the power that is adjacent to of lid is just big more, and the group number of annular convex 6 and annular recessed portion 7 is many more, and the power that is adjacent to of lid is just big more.In addition, the power that is adjacent to of lid is big more, and power required when sealing again is just big more, and therefore the power that is adjacent to of lid is preferably below 50N.
The mensuration of the power that is adjacent to of lid is performed such: the container body that will add the airtight container of loam cake is fixed, end face jointing metal system anchor clamps at lid, utilize the traction test machine with the speed drawing metallic anchor clamps that 50mm/ divides, any part that is determined at annular recessed portion 7 breaks away from annular convex 6 stress constantly.
In the airtight container with resealability that present embodiment relates to, preferably, when effect had predetermined load on the peripheral part of lid 2 and oral area 3 overlapping areas, the deflection of oral area 3 was less than the deflection of lid 2.2 harder by making oral area 3 than covering, can guarantee to cover 2 leak tightness, there is not the leakage of content substantially.By making the wall thickening or making oral area 3 crystallizations, can improve the hardness of oral area 3.
In addition, as shown in Figure 1, lid 2 forms, and when annular convex 6 and annular recessed portion 7 were chimeric, the end face on the tube top of oral area 3 was adjacent to the inside face of lid 2, thereby can further improve the leak tightness of content.
Shown in the airtight container 100 as shown in Figure 1 like that, in the airtight container that present embodiment relates to resealability, preferably, to be stuck on the neck ring 14 in the hook portion 18 of an end setting of flange 16, and will be stuck at the handgrip 15 of the other end setting of flange 16 on the ring 13, cover 2 opener thereby be provided with.
Below, variety of way is shown in Fig. 1, Fig. 3 and Fig. 4 particularly, and to suppressing oral area 3 deformed configurations in the body 4 and describe when when body 4 effect has stress, being limited to by the distortion with body 4.
Fig. 3 is the scheme drawing of graphic representation situation of the distortion during imposed stress on the airtight container shown in Fig. 1 100, (a) state before the expression distortion, (b) state after the expression distortion.As shown in Figure 3, the so-called deformed configurations that suppresses oral area 3, be structure as described below specifically: when on the arbitrary position at the body 4 of container body 1 during imposed stress 10 (Fig. 3 (a)), generate depression part 11 even on body 4, be out of shape, depression part 11 also can be blocked by shoulder 8 and can not be delivered to oral area 3 places (Fig. 3 (b)), thereby is difficult for generating distortion at oral area 3.
Suppress oral area 3 deformed configurations in order to become, at first first, structure as shown in Figure 1 is such, preferred container body 1 has following structure: in the part of leaving more than the oral area 330mm, have the maximum or roughly maximum body 4 of container body diameter, and between body 4 and oral area 3, have shoulder 8 as grip part.Container body 1 becomes so-called doleiform, and then becomes the structure that oral area 3 and body 4 are separated.By grip part is set, imposed stress easily on as the body 4 of grip part only.This is because collision is on the position of container body diameter maximum mostly.And then, even body stress and being out of shape, by the transmission that shoulder 8 also can block distortion is set.Oral area 3 and body 4 overstepping the bounds of propriety from, to distortion transmit to block effect big more.Therefore, the interval between oral area 3 and the body 4 is good more than 30mm.By adopting this structure can prevent oral area 3 distortion, therefore consequently, the content that is filled in the container body 1 is difficult for leaking.
Fig. 4 is the signal longitudinal diagram of the another way of the airtight container with resealability that relates to of expression present embodiment, (a) be situation in 3 the scope from body 4 to oral area with shoulder 8 shapes that ratio that diameter is dwindled changes, (b) be situation about having by compare the shoulder 8 that the thicker wall of wall thickness forms with body 4, (c) being the situation with shoulder 8 of crystallization, (d) is the situation that is circumferentially with rib shape ring stiffener in the outer wall upper edge of oral area 3 or shoulder 8.Herein, in Fig. 4 (a)～(c), owing to axis X symmetry with respect to container, the therefore description of having omitted left half.And in Fig. 4 (d), illustrated the oral area 3 that covers at 2 o'clock has not been installed.
