The specific embodiment

Below in conjunction with accompanying drawing the utility model is made and to be further specified.

In conjunction with illustrated in figures 1 and 2, Wrapping case 1 of the present utility model comprises an accommodation tube of taking in freshness-retaining film roll 82, two end cap 4 and slip cutters 6 that are used to cut preservative film 7 that seal the axial two ends 3 of accommodation tube respectively.

Wherein, accommodation tube 2 comprises a barrel 13, and this barrel 13 upwards is non-closed form in week, and is limited with the space S of holding ccontaining freshness-retaining film roll 8.This accommodation tube 2 also comprises the first bending part 13a and the second bending part 13b that bends inwards respectively from the circumferential two ends of barrel 13, the first bending part 13a and the second bending part 13b are oppositely arranged, has a slit 11 that supplies the preservative film 7 on the freshness-retaining film roll 8 to stretch out between the opposite face of the first bending part 13a and the second bending part 13b, as shown in Figure 2, a part of preservative film 7 stretches out from this slit 11.Preferably, the first bending part 13a is an arc surface with respect to the opposite face of the second bending part 13b, and the second bending part 13b is the inclined-plane with respect to the opposite face of the first bending part 13a.The upper wall of barrel 13 also is provided with deep-slotted chip breaker 16 that caves inward and the chute 17 that caves inward.Deep-slotted chip breaker 16 is between the second bending part 13b and chute 17, and the user can pinch thumb in this deep-slotted chip breaker 16 when arresting Wrapping case of the present utility model, make be affectedly bashful convenient and stable.The peristome of chute 17 is narrower than the bottom of chute 17, and slip cutter 6 is embedded in this chute 17 and can get loose, and can move back and forth in this chute 17.The inwall upper edge of barrel 13 circumferentially is interval with many strengthening ribs 36, each strengthening rib 36 extending axially along accommodation tube 2.The bulk strength that strengthening rib 36 has strengthened accommodation tube 2 is set.

End cap 4 have one with the suitable perisporium 19 of cross-sectional profile of accommodation tube 2, on the inwall of end cap 4, be provided with an axially extended support sector 22 and a fitting portion 21 to accommodation tube, fitting portion 21 is arranged between perisporium 19 and the support sector 22, and the inner peripheral surface of fitting portion 21 is located at support sector 22 polylith floor 26 on every side with the outer peripheral face of support sector 22 by ring and links to each other.Prop up respectively in the support sector 22 that is held in these two end caps rotationally at the two ends of freshness-retaining film roll 8, floor 26 is the inclined-plane towards the end face of freshness-retaining film roll one side, can prop up the end of freshness-retaining film roll 8, stop freshness-retaining film roll 8 to move vertically, the perisporium 19 of end cap 4 is enclosed within outside the accommodation tube 2.

Fig. 3 A and Fig. 3 B at length show the structure of slip cutter of the present utility model.Slip cutter 6 comprises knife rest 27 and blade 28.Wherein, knife rest 27 is made up of the first support 33A and the second support 33B, and the structure of this first support 33A and the second support 33B is identical, is to adopt a mold moulding to make, thereby can plays the effect that reduces manufacturing cost.In the drawings, the first support 33A and the second support 33B are that benchmark is symmetrical arranged with division plane M, are entrenched togather by many groups fitting portion 34, there is shown three pairs of fitting portions 34 on the second support 33B, and every pair of fitting portion 34 is the benchmark balanced configuration with line of centers C.Every pair of fitting portion 34 is a concavity in the side of line of centers C, is convex at the opposite side of line of centers C, makes win support 33A and the second support 33B can realize concavo-convex chimeric.Blade 28 is fixed on a pair of fitting portion 34 by a pair of through hole 28b that is arranged on this blade, this blade 28 be shaped as V-arrangement, the blade 28a of blade 28 protrudes from outside the knife rest 27.The lower end of knife rest 27 forms a fitting portion 29, and this knife rest 27 is entrenched in the chute 17 by this fitting portion 29.

Accommodation tube of the present utility model adopts PPT synthetic resin extrusion forming, and its integral body can elastic deformation, makes the gap width of winning between the bending part 13a and the second bending part 13b can realize among a small circle adjustment.When needs extract preservative film 7 from Wrapping case 1,, can pull out preservative film 7 very smoothly because the second bending part 13b is the inclined-plane with respect to the opposite face of the first bending part 13a.And when needs cut off preservative film, user's a hand is normally held accommodation tube 2, thereby can apply a subtend squeezing pressure to the first bending part 13a and the second bending part 13b very naturally, make the opposite face of win the bending part 13a and the second bending part 13b closer to each other, the width in slit 11 diminishes, and then compress preservative film 7, be beneficial to cut off.
